TY - JOUR T1 - Thermodynamic Properties of Complex Actinide Alloys AN - 1372611389; 18029221 AB - Nuclear fuels for fast spectrum nuclear reactors raise challenging questions on the role of minor actinides and fission products and gases on properties and performance. Hence, prediction of phase stability trends and phase diagrams of complex actinide-based alloys is undoubtedly required to be able to predict materials performance. CALPHAD, combined with first-principles electronic structure results, is a powerful tool to predict the thermodynamic properties of actinide-based multi-component alloys. After a brief review of the available knowledge on {Am,Np,Pu,U,Zr} that are the basis for candidate metallic fuels, we focus on two examples, Am-Pu and Mo-U, for which ab initio input provides useful guidance for well-chosen experiments that can lead to full validation and verification of the thermodynamic driving force that is critically needed for subsequent work on materials evolution and performance.

This holds true particularly for BCC and HCP metals. The extent of twinning under such conditions will be explored for the case of polycrystalline Ta, which has been deformed in compression at liquid nitrogen temperatures under strain rates ranging from quasi-static rates (10(-4)/s) to dynamic conditions without pressure (10(4)/s). Samples have also been tested at high rates (up to 10(8)/s) using laser-based shock compression drives. Postmortem analysis using ESBD and TEM has revealed the influence of the prior deformation substructure on the onset of twinning. The implication of these observations on a critical stress based criterion for the onset of twinning will be examined.

This is a problem when devising models particularly when experimental data are sparse or lacking. Many thermodynamical approaches are available but a recent proposal is a very efficient approach based on a self-consistent procedure to calculate temperature-dependent lattice dynamics from first-principles theory. In this presentation we combine highly accurate all-electron DFT calculations with the self consistent ab initio lattice dynamics (SCAILD) methodology to calculate thermodynamic properties of bcc uranium.

AN - 959111936; 2012-035897 AB - Quartz sand in the eastern Mediterranean coastal plain is supplied through an extended transport system, which includes the Nile River, east Mediterranean longshore currents, and inland eolian transport. While the concentrations of cosmogenic nuclides ( (super 26) Al and (super 10) Be), and their ratio, in modern sand deposited along the coast of the eastern Mediterranean reflect the combined effect of exposure and burial during transport, the concentrations of these nuclides in buried sands are the result of decay of this initial dosing. Samples of modern exposed sand (n = 3) collected from the coastal plain of Israel yield an average (super 26) Al/ (super 10) Be ratio of 4.8+ or -0.2, significantly lower than the expected ratio of 6.8 for exposed quartz grains at the surface. A similar ratio of 4.5+ or -0.3 was measured in a late Pleistocene sand sample, indicating similar exposure-burial histories during transport in spite of the difference in climatic conditions. The results imply a steady, preburial cosmogenic nuclide ratio related to the Nile River's ability, through storage and recycling, to buffer the effects of climatic and tectonic perturbations on cosmogenic nuclide concentrations in the transported quartz. All ancient and buried sand samples (n=11) fall on a decay path that originates from the concentrations and ratio of (super 26) Al and (super 10) Be in modern sand, suggesting steady preburial concentrations of cosmogenic nuclides in quartz sand over the past 2.5 m.y.

Analysis of observations and climate model results shows that previously rare (5th percentile) summertime average temperatures are presently occurring with greatly increased frequency in some regions of the 48 contiguous United States. Broad agreement between observations and a mean of results based upon 16 global climate models suggests that this result is more consistent with the consequences of increasing greenhouse gas concentrations than with the effects of natural climate variability. This conclusion is further supported by a statistical analysis based on resampling of observations and model output. The same climate models project that the prevalence of previously extreme summer temperatures will continue to increase, occurring in well over 50% of summers by mid-century.

AN - 919956466; 22302683 AB - In vertebrate cells, the five RAD51 paralogs (XRCC2/3 and RAD51B/C/D) enhance the efficiency of homologous recombination repair (HRR). Stalling and breakage of DNA replication forks is a common event, especially in the large genomes of higher eukaryotes. When cells are exposed to agents that arrest DNA replication, such as hydroxyurea or aphidicolin, fork breakage can lead to chromosomal aberrations and cell killing. We assessed the contribution of the HRR protein RAD51D in resistance to killing by replication-associated DSBs. In response to hydroxyurea, the isogenic rad51d null CHO mutant fails to show any indication of HRR initiation, as assessed by induction RAD51 foci, as expected. Surprisingly, these cells have normal resistance to killing by replication inhibition from either hydroxyurea or aphidicolin, but show the expected sensitivity to camptothecin, which also generates replication-dependent DSBs. In contrast, we confirm that the V79 xrcc2 mutant does show increased sensitivity to hydroxyurea under some conditions, which was correlated to its attenuated RAD51 focus response. In response to the PARP1 inhibitor KU58684, rad51d cells, like other HRR mutants, show exquisite sensitivity (>1000-fold), which is also associated with defective RAD51 focus formation. Thus, rad51d cells are broadly deficient in RAD51 focus formation in response to various agents, but this defect is not invariably associated with increased sensitivity. Our results indicate that RAD51 paralogs do not contribute equally to cellular resistance of inhibitors of DNAreplication, and that the RAD51 foci associated with replication inhibition may not be a reliable indicator of cellular resistance to such agents.

However, such changes must be viewed in a long-term (millennial-scale) context if we are to understand their significance for future stability of the Antarctic ice sheets. To address this, we present nine new cosmogenic (super 10) Be exposure ages from sites on NW Alexander Island and Rothschild Island (adjacent to the Wilkins Ice Shelf) that provide constraints on the timing of thinning of the Alexander Island ice cap since the last glacial maximum. All but one of the (super 10) Be ages are in the range 10.2-21.7 ka, showing a general trend of progressive ice-sheet thinning since at least 22 ka until 10 ka. The data also provide a minimum estimate (490 m) for ice-cap thickness on NW Alexander Island at the last glacial maximum. Cosmogenic (super 3) He ages from a rare occurrence of mantle xenoliths on Rothschild Island yield variable ages up to 46 ka, probably reflecting exhumation by periglacial processes.

However, laboratory-scale reaction rates may not necessarily reflect the reactive transport scenarios at the field scale. Thus, a major challenge for field-scale modeling is the determination of reaction kinetics and rates. The conventional inversion of reaction rates relies on optimization approaches that require expensive computation to obtain the gradient of objective functions. In this manuscript, we present a combined simulation-emulation approach for calibrating the first-order reaction rates at the field scale. A number of sample points are adaptively selected to represent the high-dimensional parametric space including dimensions of reaction rates. Correspondingly, reactive transport models are generated and executed for constructing response surfaces of objective functions. Taking the advantage of smooth response surfaces, optimization of reaction rates is efficiently performed. For several benchmark cases, the advantage of using global sensitivity analysis and uncertainty quantification of the objective functions in terms of uncertain reaction rates is demonstrated.

The model may be more generally applicable to multicomponent turbulent hydrodynamics and to subgrid turbulent transport of momentum, composition and energy. As in the case of the von Neumann artificial viscosity and many subgrid-scale models for large-eddy simulation, the turbulent diffusivity explicitly depends on the grid size and is not based on a quantitative model of the unresolved turbulence. In order to address the issue that it is often not known a priori when and where a flow will become turbulent, the turbulent diffusivity is set to zero when the flow is expected to be stable on the basis of a Richardson/Rayleigh-Taylor stability criterion, in analogy to setting the von Neumann artificial viscosity to zero in expanding flows. One-dimensional predictions of this model applied to a simple shear flow configuration are compared to those obtained using a K- member of model. The density and velocity profiles predicted by both models are shown to be very similar.

There have been numerous proposals for U.S.-Russian and NATO-Russian missile defense cooperation, but often they lack reciprocity and fail to significantly improve the security of all countries involved. This article's proposal for a joint NATO-Russian early-warning radar located in central Russia provides genuine security benefits for all countries, improves strategic stability, and involves potential industrial partnerships, which ought to be of interest to Russian semiconductor firms.

Relevant triggering mechanisms are complex and include reduction of capillary pressure due to increased saturation and frictional drag on the sediment induced by fluid flow. Physics-based continuum models utilizing modern computational tools are useful for understanding the mechanisms of deformation in partially saturated slopes; however, they do not provide a scalar indicator called 'factor of safety' that measures the potential of a given slope for mass movement. In the present work, we employ sequential calculations consisting of a physics-based finite element model that couples solid deformation with fluid flow to quantify the stress and deformation fields in a steep hillside slope subjected to rainfall infiltration. This is followed by a limit-equilibrium calculation based on the method of slices that evaluates the desired factor of safety. The field condition investigated is similar to the steep experimental catchment CB1 near Coos Bay, Oregon, which failed as a large debris flow from heavy rainfall.

Conditioning EPMs on available data reduces uncertainty and increases the reliability of model predictions. We present a rational and concise approach to investigate the impact of conditioning EPMs on data as a function of the location of the environmentally sensitive target receptor, data types and spacing between measurements. We illustrate how the concept of comparative information yield curves introduced in de Barros et al. [de Barros FPJ, Rubin Y, Maxwell R. The concept of comparative information yield curves and its application to risk-based site characterization. Water Resour Res 2009;45:W06401. doi:10.1029/2008WR007324] could be used to assess site characterization needs as a function of flow and transport dimensionality and EPMs. For a given EPM, we show how alternative uncertainty reduction metrics yield distinct gains of information from a variety of sampling schemes. Our results show that uncertainty reduction is EPM dependent (e.g., travel times) and does not necessarily indicate uncertainty reduction in an alternative EPM (e.g., human health risk). The results show how the position of the environmental target, flow dimensionality and the choice of the uncertainty reduction metric can be used to assist in field sampling campaigns.

AN - 1112672433; 2012-090076 AB - A south-north transect of Hudson River marsh sediment cores (Jamaica Bay, Staten I., Piermont, Croton, Iona, Constitution, Tivoli, Stockport) are analyzed for pollen, plant macrofossils, C and N isotopes, as well as bulk chemistry. Pollen stratigraphy in all of the cores show a striking shift with European impact, including the increase of ragweed and other weedy species from the uplands, along with a decline in tree pollen due to clearing of the landscape by the settlers. Subsequent reforestation in the twentieth century is sometimes seen with the resurgence of upland tree species, but typically the stratigraphy reveals a dramatic increase of first invasive Typha (cattail) and then Phragmites (common reed) throughout the marshes with the decline of native sedges such as Schoenplectus americanus (chairmaker's bulrush). Macrofossil analysis indicates the dominance of these invasive species throughout the marshes, and the loss of plant diversity, probably due to increased nitrogen and expansion of Phragmites throughout the estuary. Carbon and nitrogen isotopes are correlated with these major shifts. X-ray fluorescence (XRF) data reveal increases in upland input to the marshes due to European impact, as well as increases in heavy metals.

The high-resolution AMS-dated macrofossil stratigraphic record at Green Pond, NY, in Rockland County, reveals a sequence of first mosses, then cranefly remains followed by subarctic tundra fossils. As the climate warmed and gyttja formed in the lake, boreal forest colonized the region. To the north about 30 km, Sutherland Fen, NY records spruce and willow first in the inorganic clays, followed by spruce, fir, and jack pine. Westward at Uttertown Bog, NJ, shallow aquatics record the earliest plant life, followed by larch colonization and finally spruce. The chronological relationship of these events to lake records both northward, to the west, and in the southeastern part of the US will be discussed. The timing of these terrestrial paleoclimatic reconstructions will be compared with the timing of marine events in the North Atlantic and Gulf of Mexico, European pollen stratigraphy, and ice core stratigraphy.

When greatly differing decay rates exist in a reaction network, the stiffness of ordinary differential equations increases and requires additional effort to obtain solutions numerically. Although analytical solutions are preferred, they are limited to relatively simple reaction networks and small numbers of species. In this paper, we propose a methodology for formulating analytical solutions of ODEs for an unlimited number of species and more generalized reaction networks, including multidaughter branching and multiparent converging reactions. The derivation of analytical solutions for user-defined first-order reaction networks is implicitly implemented as a generalized computer code. Then, derived analytical solutions of the first-order reactions are coupled with numerical solutions for transport using an operator-splitting scheme. The solution method is then used to obtain analytical solutions of transport systems coupled by complex decay networks.

These gas-phase measurements, without the added convolution with evaporation times, were made possible by using an aerosol shock tube. The fuels studied include three large normal alkanes, n-decane, n-dodecane and n-hexadecane; one large methyl ester, methyl decanoate; and several diesel fuels, DF-2, with a range of cetane indices from 42 to 55. The reflected shock conditions of the experiments covered temperatures from 838 to 1381 K, pressures from 1.71 to 8.63 atm, oxygen concentrations from 1 to 21%, and equivalence ratios from 0.1 to 2. Ignition delay times were measured using sidewall pressure, IR laser absorption by fuel at 3.39 mu m, and CH* and OH* emission. Measurements are compared to previous studies using heated shock tubes and current models. Model simulations show similar trends to the current measurement except in the case of n-dodecane/21% O2/argon experiments. At higher temperatures, e.g. 1250 K, the measured ignition delay times for these mixtures are significantly longer in lean mixtures than in rich mixtures; current models predict the opposite trend. As well, the current measurements show significantly shorter ignition delay times for rich mixtures than the model predictions.

The introduction of X-ray free-electron lasers makes it possible to pump new atomic X-ray lasers with ultrashort pulse duration, extreme spectral brightness and full temporal coherence. Here we describe the implementation of an X-ray laser in the kiloelectronvolt energy regime, based on atomic population inversion and driven by rapid K-shell photo-ionization using pulses from an X-ray free-electron laser. We established a population inversion of the K alpha transition in singly ionized neon at 1.46 nanometres (corresponding to a photon energy of 849 electronvolts) in an elongated plasma column created by irradiation of a gas medium. We observed strong amplified spontaneous emission from the end of the excited plasma. This resulted in femtosecond-duration, high-intensity X-ray pulses of much shorter wavelength and greater brilliance than achieved with previous atomic X-ray lasers. Moreover, this scheme provides greatly increased wavelength stability, monochromaticity and improved temporal coherence by comparison with present-day X-ray free-electron lasers.

The evaporation is strongly governed by surface processes and intrinsic nature of the substance. A thorough knowledge of the atomistic evaporation mechanism is fundamental for better understanding reaction kinetics between gas and condensed materials in general. We have conducted a series of evaporation experiments of forsterite in vacuum for crystallographically oriented surfaces at 1500 to 1810 degrees C. The (100), (010), and (001) surfaces developed their own morphology characterized by evaporation pits and grooves originated from dislocation outcrops. Nominal overall evaporation rate (average retreat rate of a surface) shows significant anisotropy with the maximum difference by a factor of five below 1740 degrees C. The overall evaporation rates for individual surfaces are fitted with respective Arrhenius relationships, giving the highest activation energy for (100), intermediate for (001), and the lowest for (010). The anisotropy decreases to within 50% at approximately 1800 degrees C, which is caused by enhancement of evaporation from (010) owing to preferential evaporation around dislocation outcrops. "Intrinsic evaporation rates" estimated by subtracting contributions of initial roughness and the preferential evaporation around dislocations from the nominal overall evaporation rates show substantial anisotropy even at approximately 1800 degrees C. The "intrinsic evaporation rate" for (010) is adequately fitted by an Arrhenius relationship over the examined temperature range giving a single activation energy of 655 kJ/mol. The prevalence of steps with submicrometer to nanometer-scale height shows that forsterite evaporates mostly by layer-by-layer mechanism. The only exception is the (001) surface above approximately 1650 degrees C, on which such steps are absent except for surface-parallel minor facets which are rapidly diminishing with time. The (001) surface is inferred to evaporate by direct detachment mechanism at high temperatures. The change of evaporation mechanisms for (001) at around 1650 degrees C corresponds to a rough-smooth transition kinetically induced by an atomistic evaporation process.

Although feedbacks are integrated quantities, the processes from which they arise have rich spatial structures that alter the distribution of top of atmosphere (TOA) net radiation. Here, the authors investigate the implications of the structure of climate feedbacks for the change in poleward energy transport as the planet warms over the twenty-first century in a suite of GCMs. Using radiative kernels that describe the TOA radiative response to small perturbations in temperature, water vapor, and surface albedo, the change in poleward energy flux is partitioned into the individual feedbacks that cause it. This study finds that latitudinal gradients in the sum of climate feedbacks reinforce the preexisting latitudinal gradient in TOA net radiation, requiring that the climate system transport more energy to the poles on a warming planet. This is primarily due to structure of the water vapor and cloud feedbacks, which are strongly positive at low latitudes and decrease dramatically with increasing latitude. Using the change in surface fluxes, the authors partition the anomalous poleward energy flux between the atmosphere and ocean and find that reduced heat flux from the high-latitude ocean further amplifies the equator-to-pole gradient in atmospheric energy loss. This implied reduction in oceanic poleward energy flux requires the atmosphere to increase its share of the total poleward energy transport. As is the case for climate sensitivity, the largest source of intermodel spread in the change in poleward energy transport can be attributed to the shortwave cloud feedback.

Here, we conduct a series of idealized experiments with the Community Climate System Model to analyze the potential impact on boreal climate of a large-scale tundra-to-shrub conversion. The model responds to an increase in shrub abundance with substantial atmospheric heating arising from two seasonal land-atmosphere feedbacks: a decrease in surface albedo and an evapotranspiration-induced increase in atmospheric moisture content. We demonstrate that the strength and timing of these feedbacks are sensitive to shrub height and the time at which branches and leaves protrude above the snow. Taller and aerodynamically rougher shrubs lower the albedo earlier in the spring and transpire more efficiently than shorter shrubs. These mechanisms increase, in turn, the strength of the indirect sea-ice albedo and ocean evaporation feedbacks contributing to additional regional warming. Finally, we find that an invasion of tall shrubs tends to systematically warm the soil, deepen the active layer, and destabilize the permafrost (with increased formation of taliks under a future scenario) more substantially than an invasion of short shrubs.

The objective of this study was to assess the effects of future projected climate change on the hydrology and the leaching of heavy metals (i.e. Cd and Zn) in the catchment. The numerical, quasi-2D, unsaturated zone Soil Water Atmosphere Plant model was used with 100-year simulated daily time series of precipitation and potential evapotranspiration. The time series are representative of stationary climates for the periods 1961-1990 ("baseline") and 2071-2100 ("future"). The time series of future climate were obtained by downscaling the results of eight regional climate model (RCM) experiments, driven by the SRES A2 emissions scenario, using change factors for a series of climate statistics and applying them to stochastic weather generator models. The time series are characterized by increased precipitation in winter, less precipitation in summer, and higher air temperatures (between 2 degree C and 5 degree C) throughout the year. Future climate scenarios project higher evapotranspiration rates, more irrigation, less drainage, lower discharge rates and lower groundwater levels, due to increased evapotranspiration and a slowing down of the groundwater system. As a result, lower concentrations of Cd and Zn in surface water are projected. The reduced leaching of heavy metals, due to drying of the catchment, showed a positive impact on a limited aspect of surface water quality.

Here we performed high-resolution TEM using a fluid cell to directly observe attachment of iron oxyhydroxide nanoparticles. Images were recorded with lattice fringe-resolution, enabling us to track particle orientations throughout the experiments. We find that the primary particles undergo continuous rotation and interaction until they find a perfect lattice match. A sudden "jump to contact" then occurs over < 1nm, followed by lateral atom-by-atom addition initiated at the contact point. Interface elimination proceeds at a rate consistent with the curvature-dependence of the Gibbs free energy. From the measured translational and rotational accelerations we calculate the magnitude of the inter-particle forces. The results show that highly-direction-specific interactions drive crystal growth via OA, and are likely the result of electrostatic forces. The findings of this study provide a dynamic view of the process of OA and answer the essential question of whether co-alignment occurs prior to attachment or comes about afterwards. In the case of freely diffusing nanoparticles, either near-perfect crystallographic orientation or a specific twin orientation that ensures interfacial coherence is required for attachment to occur. The results also shed light on the magnitude and nature of the forces that drive OA.

Uranium- series disequilibria represent one of few methods of measuring absolute crystal ages in young volcanic systems, thereby placing chemical, textural, and/or isotopic data in a temporal framework. We present here a synthesis of our recent work [1-5] combining U-series crystal ages with other types of information, which provides new insights into magmatic processes. Intermediate magmas erupted at Volcan Quizapu, Chile, and Mt. Hood, USA, are the result of mixing of silicic and mafic magmas. We used U-series ages of plagioclase in combination with crystal size distributions, trace-element zoning, and diffusion modeling to constrain both the pre-mixing and post-mixing storage times of crystals [3-5]. Plagioclase in both systems have U-series ages of ka to tens of ka, representing the total average storage time of the crystals. In contrast, diffusion modeling permits a maximum of days to weeks of crystal storage in the host magmas post-mixing. These data suggest that crystals remain in the 'active' (i.e., eruptible) part of the reservoir for thousands of years yet eruption follows quickly on mixing. Studies of crystals in rhyolitic systems of different volumes may provide insights into processes that are common in silicic melt generation yet may be obscured in larger systems. We have analyzed zircon and plagioclase in three rhyolitic systems ranging from small (South Sister, USA [2]) to intermediate (Okataina Caldera Complex, New Zealand [1]) to large (Yellowstone, USA). Combinations of age data with trace-element and Hf isotopic compositions show the coeval presence of chemically-distinct magma or mush bodies in all three systems; only Yellowstone shows evidence for effective homogenization of the liquid fraction of the magma prior to eruption. If these results generally hold for other systems, it would imply that (only) the largest silicic eruptions are preceded by accumulation of a significant body of liquid that remains in the subsurface long enough to homogenize. Such bodies would likely be detectable by seismic imaging prior to eruption.

To avoid method-related artifacts that are associated with the common physical soil fractionation techniques, non-invasive high-resolution imaging techniques have been recently developed to simultaneously determine the molecular composition, source and fate of added OM, and location of OM within soil micro-aggregates. Simultaneous high-resolution chemical characterization and isotope tracing can be achieved by combining nano-scale imaging mass spectrometry (NanoSIMS) and spatially resolved spectroscopy (STXM/NEXAFS). These techniques allow precise, high-resolution, quantitative measurement of molecular and isotopic patterns in an undisturbed sample. In a series of recent experiments, we combined these techniques to map organic carbon distribution, and image associations of organics with specific metal-oxide minerals in soil. In these experiments, we used 15N- and 13C-organic matter incubations and NanoSIMS imaging to track the fate of specific microbial and plant polymers. This has allowed us to measure preferential OM associations with Fe and Mn oxides and clay particles. Using synchrotron-based scanning transmission X-ray microscopy (STXM) analysis of the same microstructures, we can then measure the molecular class of these particles, for example, thin amine N coatings covering Fe (hydr)oxides, and microbial lipids coating montmorillonite particles. These high-resolution imaging approaches are complementary to more traditional bulk analyses (14C dating, NMR, density fractionation) and can yield mechanistic explanations for processes which influence organic matter decomposition in soil. This work was performed under the auspices of the U.S. Department of Energy by Lawrence Livermore National Laboratory under Contract DE-AC52-07NA27344.

This microbial respiration requires organic carbon, and it is this source of organic carbon that is poorly constrained. It has been hypothesized that the carbon could be derived from: 1) young anthropogenic sources, 2) carbon deposited with the sediments, 3) carbon from organic rich peat lenses, or 4) older petroleum byproducts. However, no method is currently available to directly determine the source of organic carbon. In order to better constrain the source of organic carbon we developed a method to determine the radiocarbon signature of microbial DNA and phospholipids fatty acids (PLFAs) from groundwater samples. The radiocarbon signatures of the DNA and PLFA will reflect the source of organic carbon utilized by heterotrophic microbes. For DNA, the method includes filtering over 2,000 liters of groundwater onto a 0.2 mu m filter followed by DNA extraction and purification. For PLFAs the method includes filtering over 1,000 liters of groundwater onto a newly developed carbon free filter. The DNA method enables us to collect, extract, and purify over 150 mu g of DNA with an absorbance at 260/280>1.8 and an A260/230>2; indicating pure DNA. The new method was utilized at Site F in the Lashkardi Village, Araihazar, Bangladesh. The site represents an area where rapid recharge of anthropogenic carbon might occur. Results indicate that in the Holocene Aquifer the DNA is significantly older than groundwater ages and does not contain modern carbon but is younger than estimated sediment ages. We hypothesize that the carbon in the aquifer is recharged at the water table and is significantly retarded as it is tranported to depth. Further utilization of this novel method should help to better constrain the carbon sources driving arsenic release in the shallow aquifers of Southeast Asia.

Calcite, wollastonite II and monticellite were identified among other mineral inclusions of carbonatitic association in diamond from the Juina area, Mato Grosso State, Brazil. Two mineral associations were selected for this study: calcite + nyerereite + wollastonite II + CaZr-garnet (#1734) and calcite + monticellite + cuspidine (#1598). The analyses were carried out using the LLNL NanoSIMS 50. A 0.3 pA, 80 nm diameter, Cs (super +) beam rastered over a 4 X 4 mm (super 2) area produced quantitative secondary ion images. The external precision was < 4ppm for delta (super 18) O and < 9ppm for delta (super 13) C. The results are presented in the following table. Despite great error values (all at 1 sigma), the two samples demonstrate significant differences in their isotopic characteristics. Data for sample #1734 are close to average mantle characteristics, while data for sample #1598 demonstrate its possible origin from deeply-subducted oceanic crust. However, both data correspond to the terrestrial fractionation line, and isotope fractionation processes during the course of the origin of the analyzed minerals cannot be excluded.

One of the main driving forces in changing the chemical, biological, and physical properties of the rhizosphere is the exudation of low molecular weight (LMW) organic compounds by the root. LMW exudates represent a significant C flux into soil ecosystems; compounds such as simple sugars, organic acids, and phenols have also been shown to facilitate cycling of redox active metals (e.g., Fe and Mn). This phenomenon is not only observed in aquic and poorly drained soils, but seems to be common in any upland soil with moisture regimes other than aridic or xeric. In the research presented here we assumed that LMW exudates and microbial activity in the rhizosphere act together to create redox active microsites in soil. We further hypothesize that redox active microsites are short-lived and continuously recreated, thereby generating a steady supply of reactive manganese (Mn) species. This rhizosphere redox cycling may control the availability of reactive forms of Mn that have been mechanistically linked to the oxidative breakdown of complex organic substrates such as lignin. We tested our hypothesis by examining the effect of different LMW exudates (oxalate, glucose, acetate, and vanillin) on the Mn dynamics of two different soil types in rhizosphere microcosms. Artificial roots allowed for the release of LMW exudates into structurally intact soil at realistic rates. Results from O (sub 2) microsensor measurements as well as bulk and spectroscopic analyses show how root exudates vary in their ability to (i) induce reducing conditions, (ii) influence the activity of lignolytic enzymes, and (iii) affect the abundance and speciation of reactive Mn species in the rhizosphere. Our results indicate that Mn redox cycling in the rhizosphere may be plant-driven. If confirmed for natural soil environments, the exudates-induced formation of reactive Mn species may have important implications for the turnover of complex biopolymers such as lignin in the rhizosphere.

In these watersheds, the predicted climate change impacts on snowmelt will likely alter the amount and timing of groundwater recharge, which may lead to reduced groundwater production, declining water tables, and reduced baseflow to streams. We apply dissolved noble gas tracers to answer questions about recharge location and aquifer residence times in two catchments of differing size in the northern Sierra Nevada. The Olympic Valley near Lake Tahoe is a 22 km (super 2) alpine catchment while the Upper Merced catchment has an area of 465 km (super 2) and drains through Yosemite Valley. In both valleys, deep, high capacity production wells located in the upper portion of the valley draw groundwater from over much of the sediment thickness. These wells were sampled for tritium and dissolved noble gases in order to determine recharge temperatures (used to estimate to recharge elevation), and tritium-helium groundwater ages. Noble gas recharge temperatures point to the lower slopes of the mountains, just above the valley floor, as important recharge areas for both catchments. Tritium-helium aquifer residence times are somewhat greater in Yosemite Valley wells (10-28 years) than in Olympic Valley wells (<1-23 years), but in both areas the results indicate relatively rapid turnover of groundwater in the coarse alluvium of the upper valley reaches. The much larger Upper Merced catchment thus supplies only somewhat greater buffering to perturbations in recharge and runoff that would be expected due to warmer temperatures. Using the information gathered from these tracers, differing scenarios characterized by earlier snowpack melting and a higher proportion of precipitation as rain are evaluated with regard to potential impacts to recharge.

More than two decades ago, geochemical analyses of deep-sea sediments in the Atlantic Ocean revealed that the distribution of water masses and their characteristics were significantly different at the LGM and other times in the past when compared to modern observations. Although some of the paleodata have been reproduced and shown to be robust, there has been continued debate about the implications of these results for the dynamics of the large-scale circulation and the consequences for the storage and transport of heat, freshwater, nutrients and carbon in the past. There is also no consensus on the variations in water mass and dynamics that occurred between the LGM and the establishment of the modern Atlantic circulation despite the development of time series and maps of more than a half dozen paleo proxies for various aspects of the circulation. Here we present a discussion of new and previously published Pa/Th, delta (super 13) C, SS, epsilon Nd, Delta (super 14) C, Cd/Ca, B/Ca, Zn/Ca and other data. We consider which aspects of past circulation during the LGM and deglaciation are robustly established and which remain open to competing interpretations. These results combine to confirm that the Atlantic circulation was different both in terms of water masses and their fluxes. The LGM Atlantic was characterized by rapidly overturning intermediate waters, consisting of more than one water mass, most likely of northern origin, and southern-sourced deeper waters with a longer residence time in the basin. Early in the deglaciation, during the H1 iceberg discharge and ensuing stadial, the boundary between intermediate and deep water masses shoaled, although a shallower overturning cell persisted throughout. We seek to reconcile apparently conflicting new and existing proxy evidence regarding any substantial change in the rate of deep water production and residence time during H1. Shortly after 15 ka, nearly all proxies indicate a rejuvenation of deep overturning, followed by a reduction during the Younger Dryas event (12.7-11.5 ka), and the subsequent development of the modern Atlantic circulation in the Holocene.

Information on the history and on the potential origin of intercepted nuclear material can be obtained through nuclear forensic analysis. Using commonly available techniques of mass spectrometry, microscopy and X-ray diffraction, we have gained insight into the processing and origin of a suite of uranium ore concentrate (UOC) samples. The 33 UOC samples are in the form of ammonum di-uranate (ADU). The sample suite is thought to represent a time series collected at the same location over a number of years. The rare earth element (REE) patterns match the REE patterns for phosphorites reported in, implying that the samples are derived from a phosphorite deposit (Figure 1). The REE patterns are fairly consistent throughout the series, although absolute concentrations of REEs decrease through the time sequence (Figure 1) suggesting improvements in metallurgy with time. The U purification process appears to be OPPA solvent extraction based on the form of the UOC (as ADU). The first few samples in the time series have higher concentrations of almost all impurity elements, and lower concentrations of U, than subsequent samples. Some of the later samples have on up to 40% higher concentrations of alkali earths and alkali metals, indicating slight variations in feedstock. The consistency in trace element patterns, however, suggests the samples are derived from geologically related ore bodies. This study illustrates one way in which nuclear forensic analysis can provide insight into the ore geology and production and purification methods used to produce UOC.

A calibration was constructed utilizing Sr/Ca (sub coral) ratios and previously published Pacific Sr/Ca (sub sw) data (R (super 2) = 0.53, n = 12, p < 0.01): Sr/Ca (sub coral) (mmol/mol) = 4.62*Sr/Ca (sub sw) (mmol/mol) - 36.64. Sr/Ca (sub sw) is ultimately governed by the remineralization of Sr-containing shells of surface water-derived marine organisms (e.g., Acantharia) at intermediate water depths. California margin Sr/Ca (sub coral) records from 792 and 1295 m document fluctuations in Sr/Ca (sub sw) that appear decadal-scale. These results suggest that Sr/Ca (sub sw) may not be as stable as previously assumed and may be influenced by surface productivity on short timescales.

"plumes") on the present-day surface dynamics of the Earth. This dynamical impact can be seen in a wide range of global surface tectonic and geological observables, including plate tectonic motions, surface topography, free-air gravity or geoid anomalies Our ability to understand how the dynamics deep inside the Earth controls these surface observables has made rapid progress over the past decade. This has been achieved thanks to advances in seismic tomographic imaging of the 3-D structure in the Earth's interior and in the models that relate this structure to the process of thermal convection in the mantle. Our most recent tomography-based mantle flow simulations provide an improved understanding on how heat and mass is transported across the mantle, from the core-mantle boundary to the surface. We find values for heat flux at the core-mantle boundary (CMB) that is at least 3 to 5 time greater than traditionally estimated on the basis of surface hotspot modelling. These high amounts of heating at the bottom of the mantle are the reason for the strong upwellings in the mantle that are readily mapped out using the new joint seismic-geodynamic global tomography models. We will show how these hot upwellings. originating at the base of the mantle, not only transport large amounts of heat, but also play a crucial role in determining the spatial and temporal evolution of surface topography on our planet.

If one assumes a correlation between mantle seismic velocity anomalies and density anomalies one can test mantle dynamics hypotheses by comparing model predictions to the observed gravity field, topography, and plate motions of Earth (geodynamic data). Due to non-uniqueness in the seismic models, hypothesis testing should be done by joint inversions of the seismic data along with the geodynamic data under the assumptions of the hypothesis being tested. We have run a number of joint inversions testing mantle layering hypotheses as well as the importance of thermal versus chemical heterogeneity. Our results show that whole mantle flow is preferred to models that have strict layering within the mantle including at 660 km depth. In these inversions we test various viscosity models that are consistent with postglacial rebound data. We have also run joint inversions assuming that seismic heterogeneity is due to thermal variations using mineral physics results for the scaling of seismic to density anomalies. The results do not provide good fits to data but allowing chemically distinct cratons to 200 km depth (intrinsically buoyant) greatly improves the fit. The result of these inversions is a global three dimensional density model most consistent with thermal structure dominant in the mantle that can be tested in the future with independent observations.

The model provides a new image of Earth's interior, but the underlying practical purpose of the model is to provide enhanced seismic event location capabilities. The LLNL-G3Dv3 model is based on approximately 2.8 million P and Pn arrivals that are re-processed using our global multiple-event locator called Bayesloc. We construct LLNL-G3Dv3 within a spherical tessellation based framework, allowing for explicit representation of undulating and discontinuous layers including the crust and transition zone layers. Using a multiscale inversion technique, regional trends as well as fine details are captured where the data allow. LLNL-G3Dv3 exhibits large-scale structures including cratons and superplumes as well numerous complex details in the upper mantle including within the transition zone. Particularly, the model reveals new details of a vast network of subducted slabs trapped within the transition beneath much of Eurasia, including beneath the Tibetan Plateau. We demonstrate the impact of Bayesloc multiple-event location on the resulting tomographic images through comparison with images produced without the benefit of multiple-event constraints (single-event locations). We find that the multiple-event locations allow for better reconciliation of the large set of direct P phases recorded at 0-97 degrees distance and yield a smoother and more continuous image relative to the single-event locations. Travel times predicted from a 3-D model are also found to be strongly influenced by the initial locations of the input data, even when an iterative inversion/relocation technique is employed.

Detrital Hadean zircons (>3.8 Gyr) from the Jack Hills metasedimentary belt of Western Australia record extremely enriched Hf-isotope signals suggesting early extraction of a continental crust (>4.5 Gyr) but fail to identify a prevalent complementary depleted mantle reservoir, suggesting that crust formation processes in the early Earth were fundamentally distinct from today. However, this conclusion assumes that the Hf-isotope composition of bulk chondrite meteorites can be used to estimate the composition of Earth prior to its differentiation into major silicate reservoirs, namely the bulk silicate Earth (BSE). We report a (super 176) Lu- (super 176) Hf internal mineral isochron age of 4869 + or - 34 Myr for the pristine SAH99555 angrite meteorite. This age is approximately 300 Myr older than the age of the Solar System, confirming the existence of an energetic process yielding excess (super 176) Hf in affected early formed Solar System objects through the production of the (super 176) Lu isomer (t (sub 1/2) approximately 3.9 hours). Thus, chondrite meteorites contain excess (super 176) Hf and their present-day composition cannot be used to infer the Lu-Hf parameters of BSE. Using a revised BSE estimate based on the SAH99555 isochron, we show that Earth's oldest zircons preserve a record of coexisting enriched and depleted hafnium reservoirs as early as approximately 4.3 Gyr in Earth's history, with little evidence for the existence of continental crust prior to approximately 4.4 Gyr. This new view suggests continuous juvenile crustal growth and recycling throughout the Hadean and Archean eras, perhaps analogous to modern plate tectonics.

The capability to model, monitor, and measure the resulting fracture network is essential for optimal production. Using a sample dataset recorded from a set of surface sensors, we demonstrate the use of empirical matched filters to first detect low threshold events and then apply Bayesian-based location methods to yield locations along with robust error estimates. The error estimation is useful in relating the observed seismicity distribution to geologic models and distinguishing between features reflecting actual geologic structure as opposed to artifacts caused by sensor geometry and other sources of error. The velocity model is estimated using all available data and refined using Green's function derived from ambient noise. Next, we explore the use of full waveform modeling using adjoint methods to define the micro-seismic focal mechanism, which distinguishes between tensile and shear mechanisms in the underlying fractures. The results (locations and focal mechanisms) are compared with the known geology (such as lithologic changes and fracture orientations) of the site and with standard techniques (P/S amplitude ratio and first-motion focal mechanisms) to evaluate the validity of these methods.

The composition implies a mass-radius relation which relies heavily on equations of state calculated from electronic structure theory and measured experimentally on Earth. We lay out a method for deriving and testing equations of state, and deduce mass-radius and mass-pressure relations for key, relevant materials whose equation of state (EOS) is reasonably well established, and for differentiated Fe/rock. We find that variations in the EOS, such as may arise when extrapolating from low-pressure data, can have significant effects on predicted mass-radius relations and on planetary pressure profiles. The relations are compared with the observed masses and radii of planets and exoplanets, broadly supporting recent inferences about exoplanet structures. Kepler-10b is apparently "Earth-like," likely with a proportionately larger core than Earth's, nominally 2/3 of the mass of the planet. CoRoT-7b is consistent with a rocky mantle over an Fe-based core which is likely to be proportionately smaller than Earth's. GJ 1214b lies between the mass-radius curves for H (sub 2) O and CH (sub 4) , suggesting an "icy" composition with a relatively large core or a relatively large proportion of H (sub 2) O. CoRoT-2b is less dense than the hydrogen relation, which could be explained by an anomalously high degree of heating or by higher than assumed atmospheric opacity. HAT-P-2b is slightly denser than the mass-radius relation for hydrogen, suggesting the presence of a significant amount of matter of higher atomic number. CoRoT-3b lies close to the hydrogen relation. The pressure at the center of Kepler-10b is 1.5 (super +1.2) (sub -1.0) TPa. The central pressure in CoRoT-7b is probably close to 0.8 TPa, though may be up to 2 TPa. These pressures are accessible by planar shock and ramp-loading experiments at large laser facilities. The center of HAT-P-2b is probably around 210 TPa, in the range of planned National Ignition Facility experiments, and that of CoRoT-3b around 1900 TPa. Copyright (Copyright) 2012.

Cleanup entailed removal and collection of similar to 545 GBq of contaminated topsoil, vegetation, and debris (concrete and metal) that was subsequently entombed within an unlined crater produced by an 18 kT surface test and capped with a concrete dome. The site is now known as the Runit Dome. Currently, the US Department of Energy conducts comprehensive radiological monitoring of people living on Enewetak Atoll, but characterisation of exposure risks posed by Runit Dome have been limited to catastrophic release scenarios and periodic atoll-wide environmental surveys. Furthermore, evidence indicates open hydraulic communication between waste and intruding ocean water, with migration pathways leading to local groundwater and circulating lagoon waters. Radionuclide migration is likely facilitated by colloids and dissolution-complexation reactions under low-pH anoxic conditions.

Recently, the necessity to expand the current range of constraint-based methods to incorporate high-throughput experimental data has been acknowledged by the proposal of several methods. However, these methods have rarely been used to address cellular metabolic responses to some relevant perturbations such as antimicrobial or temperature-induced stress. Here, we present a new method for combining gene-expression data with FBA (GX-FBA) that allows modeling of genome-level metabolic response to a broad range of environmental perturbations within a constraint-based framework. The method uses mRNA expression data to guide hierarchical regulation of cellular metabolism subject to the interconnectivity of the metabolic network. Results: We applied GX-FBA to a genome-scale model of metabolism in the gram negative bacterium Yersinia pestis and analyzed its metabolic response to (i) variations in temperature known to induce virulence, and (ii) antibiotic stress. Without imposition of any a priori behavioral constraints, our results show strong agreement with reported phenotypes. Our analyses also lead to novel insights into how Y. pestis uses metabolic adjustments to counter different forms of stress. Conclusions: Comparisons of GX-FBA predicted metabolic states with fluxomic measurements and different reported post-stress phenotypes suggest that mass conservation constraints and network connectivity can be an effective representative of metabolic flux regulation in constraint-based models. We believe that our approach will be of aid in the in silico evaluation of cellular goals under different conditions and can be used for a variety of analyses such as identification of potential drug targets and their action.

Tracks have been classified into three broad types (A, B, and C), based on relative dimensions of the elongate "stylus" (in Type A "carrots") and broad "bulb" regions (Types B and C), with occurrence of smaller "styli" in Type B. From our experiments, using a diverse suite of projectile particles shot under Stardust cometary encounter conditions onto similar aerogel targets, we describe differences in impactor behavior and aerogel response resulting in the observed range of Stardust track shapes. We compare tracks made by mineral grains, natural and artificial aggregates of differing subgrain sizes, and diverse organic materials. Impacts of glasses and robust mineral grains generate elongate, narrow Type A tracks (as expected), but with differing levels of abrasion and lateral branch creation. Aggregate particles, both natural and artificial, of a wide range of compositions and volatile contents produce diverse Type B or C shapes. Creation of bulbous tracks is dependent upon impactor internal structure, grain size distribution, and strength, rather than overall grain density or content of volatile components. Nevertheless, pure organic particles do create Type C, or squat Type A* tracks, with length to width ratios dependent upon both specific organic composition and impactor grain size. From comparison with the published shape data for Stardust aerogel tracks, we conclude that the abundant larger Type B tracks on the Stardust collector represent impacts by particles similar to our carbonaceous chondrite meteorite powders.

The terraces are defined based upon morphology, elevation and dating, together with fieldwork and high-resolution satellite analysis. The majority of the CRN model ages fall within narrow ranges (<2 ka) on the four main terraces (T1, T2, T3 and T3'), and allow a detailed terrace chronology. Bounds on the terrace ages and offsets of 5 independent terraces yield consistent slip-rate estimates. The long-term slip-rate of 13.9 + or - 1.1 mm/yr is defined at the 95% confidence level, as the joint rate probability distribution of the rate derived from each independent terrace. It falls within the bounds of all the rates defined on the central Altyn Tagh Fault between the Cherchen He (86.4 degrees E) and Akato Tagh ( approximately 88 degrees E) sites. This rate is approximately 10 mm/yr less than the upper rate determined near Tura at approximately 87 degrees E, in keeping with the inference of an eastward decreasing rate due to progressive loss of slip to thrusts branching off the fault southwards but it is greater than the 9 + or - 4 mm/yr rate determined at approximately 90 degrees E by GPS surveys and other geodetic short-term rates defined elsewhere along the ATF. Whether such disparate rates will ultimately be reconciled by a better understanding of fault mechanics, resolved transient deformations during the seismic cycle or by more accurate measurements made with either approach remains an important issue.

However, the grains were captured via impact at approximately 6.1 km s (super -1) and have experienced pressures and temperatures that caused alteration. To ensure correct interpretations of comet 81P/Wild 2 mineralogy, and therefore preaccretional or parent body processes, an understanding of the effects of capture is required. Using a two-stage light-gas gun, we recreated Stardust encounter conditions and generated a series of impact analogs for a range of minerals of cometary relevance into flight spare Al foils. Through analyses of both preimpact projectiles and postimpact analogs by transmission electron microscopy, we explore the impact processes occurring during capture and distinguish between those materials inherent to the impactor and those that are the product of capture. We review existing and present additional data on olivine, diopside, pyrrhotite, and pentlandite. We find that surviving crystalline material is observed in most single grain impactor residues. However, none is found in that of a relatively monodisperse aggregate. A variety of impact-generated components are observed in all samples. Al incorporation into melt-derived phases allows differentiation between melt and shock-induced phases. In single grain impactor residues, impact-generated phases largely retain original (nonvolatile) major element ratios. We conclude that both surviving and impact-generated phases in residues of single grain impactors provide valuable information regarding the mineralogy of the impacting grain whilst further studies are required to fully understand aggregate impacts and the role of subgrain interactions during impact.

We used Ansys' AUTODYN to model impacts of micrometer-scale, and smaller projectiles onto Stardust foil (100 mu m thick Al-1100) at velocities up to 300 km s (super -1) . It is thought that impacts onto the interstellar dust collector foils may have been made by a combination of interstellar dust particles (ISP), interplanetary dust particles (IDP) on comet, and asteroid derived orbits, beta micrometeoroids, nanometer dust in the solar wind, and spacecraft derived secondary ejecta. The characteristic velocity of the potential impactors thus ranges from <<1 to a few km s (super -1) (secondary ejecta), approximately 4-25 km s (super -1) for ISP and IDP, up to hundreds of km s (super -1) for the nanoscale dust reported by Meyer-Vernet et al. (2009). There are currently no extensive experimental calibrations for the higher velocity conditions, and the main focus of this work was therefore to use hydrocode models to investigate the morphometry of impact craters, as a means to determine an approximate impactor speed, and thus origin. The model was validated against existing experimental data for impact speeds up to approximately 30 km s (super -1) for particles ranging in density from 2.4 kg m (super -3) (glass) to 7.8 kg m (super -3) (iron). Interpolation equations are given to predict the crater depth and diameter for a solid impactor with any diameter between 100 nm and 4 mu m and density between 2.4 and 7.8 kg m (super -3) .

AN - 1287378467; 2013-017969 AB - Samples returned by the Stardust mission from comet 81P/Wild 2 provide an unequaled opportunity to investigate cometary formation and evolution. Crystalline silicates have been identified in impact craters in Stardust Al foil, yet their origin is ambiguous. They may be original cometary components, or they may have grown from melt generated by impact. We have now studied experimental impacts of the calcium silicate mineral wollastonite, using scanning and transmission electron microscopy to document the relationship between impact feature shape and crystal lattice orientation in impact residue. Wollastonite can have a characteristic acicular habit, forming crater shapes that indicate crystal orientation upon impact. From extracted impact residue, we determined the lattice orientation of crystalline material for comparison with the whole particle orientation. We assume that crystallization from melt, without surviving seed nuclei, should result in randomly oriented crystallite growth, with no preferred direction for individual crystals. However, we find that the majority of crystalline material in the residue retains b-axis orientation parallel to the long axis of the crater form. This, together with impact parameter calculations and lack of Al incorporation by the residue (suggesting melting did not occur), indicates that these crystals and, by analogy, the majority of Al-free crystalline silicates in Stardust foil, are surviving remnants of the impactor. Furthermore, amorphous wollastonite residue probably did not form via melting and subsequent quenching, but instead by high-pressure amorphization or degradation of unquenchable phases. Finally, one crystal studied appears to be a new high-pressure/temperature polymorph of CaSiO (sub 3) , indicating that such polymorphs may be observed in Stardust residues in craters.

Our presentation will discuss the impacts of regulations required by the State of California Construction General Permit (CGP) for storm water runoff associated with oil and gas exploration and production activities that may cause storm water runoff and effluent discharges into surface waters. As of July 1, 2010, these regulations apply to all construction projects that disturb soil greater than one acre associated with exploration and production, including drill site preparation, the movement and placement of drilling equipment, including access roads and pipeline installation. CGP storm water monitoring requirements are based on Risk Levels (1, 2, & 3) for traditional sites such as drill pads and roads, and Type Levels (1, 2 & 3) for Linear Underground/Above Ground (LUP's) pipelines and overhead utilities. Monitoring may include field pH and turbidity measurements, suspended sediment, concentration, and non-visual pollutants three times per day during rain events. Numeric Action Levels and Numeric Effluent Limits have been set for pH and turbidity. Required Best Management Practices (BMP's) and good housekeeping practices at drill sites will be discussed that could aid in maintaining the runoff from pre-to post construction condition. As of September 1, 2011, new professional certifications are required to prepare the construction project Storm Water Pollution Prevention Plan (SWPPP) and associated activities. The SWPPP writer must be a trained Qualified SWPPP Developer (QSD) and site inspections must be conducted by a Qualified SWPPP Practitioner (QSP). These requirements and strategies for successful oil and gas operations necessary to limit soil erosion and storm water runoff will be discussed.

The model consists of the Los Alamos National Laboratory Parallel Ocean Program (POP) and sea ice model (CICE). The fidelity of the simulated mean climatological state and variability of key variables such as ice concentration, total ice area, ice thickness and drift were compared to observational data sets from satellite and ice drift buoy measurements. Basin-scale changes in the lower atmosphere/surface ocean/sea-ice in the simulated Arctic and Nordic Seas before and after the North Atlantic Oscillation (NAO) phase switch in 1995 were examined using winter composite analyses over the period 1990-1999. Ice cover changes between the two NAO phases were consistent with observations in that reduced concentrations were found in the Nordic and Barents Seas and increased values occurred in the Labrador Sea. Next we regionally evaluated the relative importance of winter anomalies of upper-ocean mixed layer net heat fluxes and of ocean temperature advection on marginal ice zone variability in the Irminger, Greenland, and Barents Seas for this ten-year period. We found that the net heat flux winter anomaly was at least four times more important than the winter anomaly of ocean temperature advection in the Greenland and Barents Seas, while it was twice as important in the Irminger Sea. The Ekman ocean temperature advection component generally dominated the geostrophic component in all three regions.

Toward this end, cytokine profiles in human blood were investigated using a human whole blood ex vivo exposure model, called WEEM. Results: Samples of whole blood from healthy volunteers were incubated with seven pathogens including Yersinia pseudotuberculosis, Yersinia enterocolitica, Bacillus anthracis, and multiple strains of Yersinia pestis, and multiplexed protein expression profiling was conducted on supernatants of these cultures with an antibody array to detect 30 cytokines simultaneously. Levels of 8 cytokines, IL-1[alpha], IL-1[beta], IL-6, IL-8, IL-10, IP-10, MCP-1 and TNF[alpha], were significantly up-regulated in plasma after bacterial exposures of 4 hours. Statistical clustering was applied to group the pathogens based on the host response protein expression profiles. The nearest phylogenetic neighbors clustered more closely than the more distant pathogens, and all seven pathogens were clearly differentiated from the unexposed control. In addition, the Y. pestis and Yersinia near neighbors were differentiated from the B. anthracis strains. Conclusions: Cluster analysis, based on host response cytokine profiles, indicates that distinct patterns of immunomodulatory proteins are induced by the different pathogen exposures and these patterns may enable further development into biomarkers for diagnosing pathogen exposure.

Two non-lethal, hemispherical blast waves, each of which corresponds to the detonation of a high explosive charge, are considered for configurations in which the body is facing either towards or away from the explosive charge. The shock wave interactions that arise when the blast wave impinges upon the head are characterized and correlated with the resulting transient surface pressures, forces, and moments on the head. The transient forces and moments are compared to those of an analytical model based upon the work of Zaslavskii et al. [J Appl Mech Tech Phys 2001; 42(3):533-7], who derived expressions for the drag force on an arbitrary-shaped body due to the interaction with a weak to moderate strength shock wave. The results of this study indicate that Zaslavskii et al.'s model provides a straightforward means of estimating the transient loads on the head during a non-lethal blast wave interaction.

Improving the combustion of these fuels in practical applications requires a fundamental understanding of large hydrocarbon combustion chemistry. This research project presents a detailed and reduced chemical kinetic mechanism for singly methylated iso-alkanes (i.e., 2-methylalkanes) ranging from C7 to C20. The mechanism also includes an updated version of our previously published C8-C16n-alkanes model. The complete detailed mechanism contains approximately 7200 species 31400 reactions. The proposed model is validated against new experimental data from a variety of fundamental combustion devices including premixed and non-premixed flames, perfectly stirred reactors and shock tubes. This new model is used to show how the presence of a methyl branch affects important combustion properties such as laminar flame propagation, ignition, and species formation.

We combined lithologic field data from the High Plains Aquifer, numerical simulations, and uncertainty quantification analysis to assess the role of aquifer heterogeneity and physical transport on the extent of CO2 impacted plume over a 100-year period. The High Plains aquifer is a major aquifer over much of the central United States where CO2 may be sequestered in depleted oil and gas reservoirs or deep saline formations. Input parameters considered included, aquifer heterogeneity, permeability, porosity, regional groundwater flow, CO2 and TDS leakage rates over time, and the number of leakage source points. Sensitivity analysis suggest that variations in sand and clay permeability, correlation lengths, van Genuchten parameters, and CO2 leakage rate have the greatest impact on impacted volume or maximum distance from the leak source. A key finding is that relative sensitivity of the parameters changes over the 100-year period. Reduced order models developed from regression of the numerical simulations show that volume of the CO2-impacted aquifer increases over time with 2 order of magnitude variance.

Clathrates are stable under high pressure and low temperatures. Recent estimates suggest that about 1600-2000 GtC of clathrates are present in oceans and 400 GtC in Arctic permafrost (Archer et al.2009) which is about 4000 times that of current annual emissions. In a warming climate, increase in ocean temperatures could alter the geothermal gradient, which in turn could lead to dissociation of the clathrates and release of methane into the ocean and subsequently into the atmosphere as well. This could be of particular importance in the shallow part of the Arctic Ocean where the clathrates are found in depths of only 300 m. In this presentation, we shall show results from our ongoing simulation of a scenario of large scale methane outgassing from clathrate dissociation due to warming ocean temperatures in the Arctic based on ocean sediment modeling. To that end we use the CESM (Community Earth System Model) version 1 with fully active coupled atmosphere-ocean-land model together with fast atmospheric chemistry module to simulate the response to increasing methane emissions in the Barents Sea, Canadian Archipelago and the Sea of Okhotsk. The simulation shows the effect these methane emissions could have on global surface methane, surface ozone, surface air temperature and other related indices.

Ground and aerial-based methods of CO2 leak detection tend to be expensive and/or site-specific. Using satellites for leak detection would allow global coverage with low long-term maintenance costs. Two satellite-based sensors for measuring atmospheric CO2 concentration are currently in orbit, namely SCIAMACHY and GOSAT. Within the next decade additional sensors are expected to be available, including OCO-2 and CarbonSat. Using the terrestrial footprint size of each instrument we estimated the minimum CO2 leak rate each instrument would be capable of detecting. The higher spatial resolutions anticipated for OCO-2 and CarbonSat should allow these sensors to detect leaks 1-2 orders of magnitude smaller than those detectable using SCIAMACHY or GOSAT, which were designed to examine large-scale patterns of CO2 distribution. The sparse spatial coverage by GOSAT makes it unviable for monitoring sequestration sites. We have developed several geospatial analytical techniques for leak/plume detection using SCIAMACHY data in the vicinity of large, isolated CO2 sources such as Jim Bridger Coal Plant, Wyoming (43 ktons/day). Techniques used include 1) comparing CO2 mixing ratio (xCO2) in subregions relative to the point source's location, 2) charting of xCO2 as a function of distance from the source and wind direction, 3) regional plume detection using linear transects perpendicular to wind direction, and 4) aggregation of CO2 data by prevailing wind direction. While these techniques failed to positively identify increased CO2 concentration from the Jim Bridger Coal Plant using SCIAMACHY data, we believe these techniques could be successfully applied to data with higher spatial resolution.

We have investigated acid leachable Li, along with other leachable ions including Mg, Ca and Sr, as geochemical proxies of salinity in lake sediments in the Mono Basin, California. All the elements in the acid leachable suite show a strong correlation with paleo-lake level estimates based on physical and stratigraphic evidence. The CaCO (sub 3) content of lake sediments, which has been shown to be a reliable proxy for lake level changes in the Mono basin and the adjoining Owens Lake basin, corresponds well with our acid-leachable proxy data.

We present a frequency-dependent multichannel Wiener filtering (MCWF) technique, which employs an adaptive least-squares method to remove coherent noise in seismic array data. The noise records on a number of reference channels are used to predict the noise on a primary channel, which can then be subtracted from the observed data. A sequence of aftershocks caused by the M (sub w) 6.1 21 February 2008 mainshock in Spitsbergen was recorded by the ARCES array in northern Norway. This aftershock sequence was filtered using the multichannel Wiener filters in both triggered and continuous modes. The Spitsbergen (SPITS) array, at a much closer distance to the source region, provides reliable reference information on the true number of detectable aftershocks. The conventional delay-and-sum beamforming combined with a band-pass filter could detect only 513 aftershocks with 181 false alarms, using a series of constraints comprised of signal-to-noise ratio, back azimuth, and slowness; the multichannel Wiener filtered results found 577 aftershocks with 165 false alarms using the same constraints. A complete automatic multichannel Wiener procedure is developed for event detection on continuous data. An appropriate signal-to-noise ratio threshold for aftershock detection of 2.7 is suggested. Compared to the beamforming method, the MCWF also reduces false alarms when detecting the same number of aftershocks.

Hence, scaling relation of these parameters can play an important role in assessing the seismic hazard for regions in which records of ground motions from potentially damaging earthquakes are not available. On February 21, 2008 at 14:16 (UTC), a magnitude 6 earthquake occurred near Wells, Nevada, where characterized by low rate of seismicity. For their aftershocks, a marked discrepancy between the observed and predicted ground motions from empirical ground motion prediction equation was reported (Petersen et al., 2011). To evaluate and understand these observed ground motions, we investigate the dynamic source parameters and their scaling relation for this earthquake sequence. We estimate the source parameters of the earthquakes using the coda spectral ratio method (Mayeda et al., 2007) and examine the estimates with the observed spectral accelerations at higher frequencies. From the derived source parameters and scaling relation, we compute synthetic ground motions of the earthquakes using fractal composite source model (e.g., Zeng et al., 1994) and compare these synthetic ground motions with the observed ground motions and synthetic ground motions obtained from self-similar source scaling relation. In our preliminary results, we find the stress drops of the aftershocks are systematically 2-5 times lower than a stress drop of the mainshock. This agrees well with systematic overestimation of the predicted ground motions for the aftershocks. The simulated ground motions from the coda-derived scaling relation better explains the observed both weak and strong ground motions than that of from the size independent stress drop scaling relation. Assuming that the scale dependent stress drop is real, at least in some specific regions, considering the differences in the stress drop between the small and large earthquake might help to enhance the prediction capability of the ground motion for the region.

From this one would assume that the oceanic ridges will move over the mantle in response to the geodynamics of the diverging plates, and do not remain fixed spatially over any protracted period of time. An analysis of the kinematics of ridge motions in the Indo-Atlantic hotspot frame of reference since 83 Ma generally supports this view, with the notable exception of the East Pacific Rise (EPR). The Pacific-Nazca/Farallon segment of the EPR north of Easter Island (27 degrees S) is oriented essentially N-S, and has produced more than 9500 km of E-W spreading in the past 80 Ma, making it the dominant ridge in the world's plate system over this interval of time. Yet despite the large amount of E-W divergence, the spreading center has maintained its longitudinal position to within <+ or -250 km of the current ridge axis. Global mantle convective flow modeling indicates that the EPR, unlike any other extensive segment of the mid-oceanic ridge system, is underlain by an active upwelling system extending from the core-mantle boundary to the surface. We suggest that the lack of E-W motion of the EPR apparent from the kinematics is a consequence of these mantle dynamics; this ridge is thus not behaving as a passive plate boundary, but is actively and directly linked to, and controlled by, whole mantle upwelling. This observation overturns the notion that ridges are always entirely passive features of the plate system. Subduction of the northern EPR beneath western North America has thus resulted in the overriding of an active upwelling system that has contributed significantly to the evolution of Basin and Range kinematics and superimposed dynamics, including significant contributions from dynamic topography.

The Genoa Fault is experiencing some of the highest strain rates and fastest Holocene slip rates in the western Great Basin. This fault was the site of at least two Holocene M approximately 7 earthquakes, including a pre-historic, but less than approximately 600 yr BP event with co-seismic displacement of 4-6 m and a penultimate event at approximately 2000-2500 yr BP (Ramelli et al., 1999). Its long-term slip rate history is only well-studied at one site on the southern segment: 0.4 +0.3/-0.1 mm/yr over both approximately 20 ky and approximately 150 ky time scales along the West Fork of the Carson River at Woodfords, CA (Rood et al, 2011). Over 10- to 200-ky time scales, our geomorphic approach is to quantify fault displacements of multiple geomorphic features, including 2 glacial outwash terraces and 2 alluvial fans. We use dGPS and ground-based LiDAR topographic data to model fault slip at the Woodfords, Mott Canyon, and Corsser Creek sites. We determine the age of offset features using Be-10 surface exposure dating techniques, including approximately 50 new Be-10 analyses. Paired surface boulders and depth profiles for each landform allow more accurate, high-resolution chronologies to be developed. By comparing offsets of different ages along individual fault segments and modeling their slip rates and uncertainties, we define how the locus, magnitude, and rate of fault slip changes through time. Paleoseismic trench studies reduce uncertainty concerning how these geomorphic offsets are produced by fault rupture. New trench data from the Fay Canyon site permits comparison of rupture patterns on the neighboring central and southern fault segments, where differences in the timing of earthquake events, displacement magnitude/event, and geometry of underlying faults are compared to the slip-rates calculated from offset geomorphic features. By integrating geologic and paleoseismic datasets, we investigate what frequency and magnitudes of earthquake rupture were required to build observed geomorphic offsets, and, specifically, whether the last and penultimate events ruptured across an ostensibly important fault-segment boundary.

Total steric change is 35mm or 0.7 mm yr-1 (27 mm, 0.55 mm yr (super -1) ) integrated to a depth of 1800 m (700 m). These are consistent with the current best steric estimates accounting for around half of total 20th century observed sea-level rise, with the remainder attributed to mass contributions from the cryosphere and changes to terrestrial storage. Of this 6 mm or 20% (3 mm or 10%) is due to globally integrated halosteric effects. The global halosteric average is comprised of a very small halosteric sea-level rise due to terrestrial ice melt (freshening) but must be dominated by errors in the globally integrated number due to the sparse data coverage and precision of salinity observations. In parts of the regional ocean such as the South Pacific, South Indian and North Atlantic basins, depth-integrated halosteric changes can account for around 50% of the long-term total steric signal. In the Atlantic, halosteric contraction strongly counteracts thermosteric expansion. Expansion in the Pacific and Southern Oceans is associated with Mode Water freshening. Regional patterns of steric change show highs along the axis of the Antarctic Circumpolar Current and in the North Pacific and Atlantic subtropical gyres. Reduced steric sea-level is found around northern Australia, the eastern Indian Ocean and the subpolar North-western Pacific. These regional patterns will be qualitatively compared to the spatial patterns provided by the ensemble mean from the Coupled Model Intercomparison Project 3 (CMIP3) 20th century (20C3M) simulations. Depth-integrated halosteric changes are the leading steric change for 34% of the area-weighted global ocean. These patterns of halosteric change reflect strengthened inter-basin salinity contrasts, consistent with an amplification of the climatological mean salinity pattern and an intensified global water cycle.

These enigmatic surface features have long suggested that the African continent is shaped by significant dynamic forcing originating in the underlying mantle. Herein we explore this dynamic forcing over the last 30 Ma by carrying out detailed backward-in-time convection simulations driven by mantle density anomalies inferred from high-resolution joint seismic-geodynamic inversions (Simmons et al., 2009). We show that the current high topography of the East African Rift system is due to the southward propagation of a topographic swell that encompassed the western margin of Arabia and the Afar region prior to 30 Ma. This rapid rise of topography dominates all other topographic changes and we find that the adjacent Congo Basin has gradually subsided over the same time period, partially in response to convective draw-down, suggesting that the basin may have been at a higher elevation than today. Lastly, we quantify the uncertainties in our simulations due to different models of mantle rheology, seismically inferred heterogeneity and surface boundary conditions.

In addition, recent diamond-cell x-ray diffraction experiments provide evidence for a phase transition from garnet to double-perovskite structures around 1 Mbar [2]. We present the results of laser-driven shock experiments on gadolinium gallium garnet (GGG) at pressures of 3 to more than 20 Mbar, obtained at the Omega-LLE and Jupiter-LLNL facilities, and compare these with the results of ab-initio molecular dynamic simulations. Velocimetry (VISAR) and pyrometry (SOP) diagnostics, and an impedance match analysis with quartz standards, provide data on the equation of state, temperature and optical reflectivity at 532 nm. No obvious phase transition is detected in the explored pressure range, but the data indicate that GGG remains surprisingly stiff up to more than 20 Mbar. We observe metallic-like reflectivity in the ultra-high pressure (possibly liquid) regime. This study could be relevant for planetary interior modeling, as many Earth and super-Earth minerals adopt the garnet and perovskite structures, and may exhibit transition to metallic and highly incompressible behavior.

Delivery rates vary by latitude due to the influence of geomagnetic field intensity and solar activity and locally due to differences in precipitation and rates of dustfall accumulation, which are responsible for depositing primary and recycled meteoric (super 10) Be to geomorphic surfaces, respectively. Because influences on delivery rate vary in space and time, recent studies emphasize the use of inventory sites where the total concentration of meteoric (super 10) Be is measured on stable landforms of known age to determine site-specific, long-term delivery rates. To date, measured long-term delivery rates typically have fallen within the range of expected rates for the site's latitude and modern annual rate of precipitation, including minor contributions of dust to the total inventory of meteoric (super 10) Be. Here, we present the results of a meteoric (super 10) Be inventory measured on a Pinedale ( approximately 15 ka) moraine within the Boulder Creek Critical Zone Observatory, Front Range, Colorado. We report a long-term delivery rate of meteoric (super 10) Be for this site of 4.2 to 4.6 X 10 (super 6) atoms/cm (super 2) /yr, significantly higher than the expected delivery rate (1 to 1.3 X 10 (super 6) atoms/cm (super 2) /yr) for its latitude (40 degrees) and annual precipitation rate (85-95 cm/yr). A detailed analysis of soils in the Front Range (of various ages) indicate that long-term dust accumulation rates are less than approximately 0.1 grams/cm (super 2) /kyr and therefore do not significantly influence the total amount of meteoric (super 10) Be delivered to geomorphic surfaces. When applied to measured concentrations of meteoric (super 10) Be in soils within the Gordon Gulch CZO catchment, our high, inventory-based delivery rate suggests that hillslopes are 10 to 40 ka younger (all post-LGM) than suggested by published precipitation based delivery rates. Furthermore, this result, combined with a long-term delivery rate calibrated nearby on the High Plains (1200 m lower in elevation and half the modern precipitation), indicates a different scaling between meteoric (super 10) Be and precipitation than recent studies would suggest.

The SSHO is located in the presently temperate climate zone of central Pennsylvania; however, sustained periglacial climate during the time of maximal extent of the Laurentide ice sheet ( approximately 19-21 ka) and deforestation during mid-19th Century charcoal production may have exerted significant influence on regolith production. Here, we quantify soil residence times and corresponding rates of regolith production and erosion on the north- and south-facing slopes at SSHO, using meteoric (super 10) Be in samples of regolith collected at 25 locations along each hillslope from ridge top to toe slope. Hillslopes within the SSHO are relatively planar, but exhibit a pronounced asymmetry; north-facing slopes are steeper ( approximately 20 degrees ) than south-facing slopes ( approximately 15 degrees ). Meteoric (super 10) Be concentrations decrease systematically with depth at all 6 profile sites. Meteoric (super 10) Be inventories are similar at the north and south ridgetop sites (1.89 + or - 0.55 at/cm (super 2) and 1.63 + or - 0.41 at/cm (super 2) , respectively) and generally increase with position downslope. Assuming that the delivery of meteoric (super 10) Be to regolith is balanced by its removal via erosion, the total meteoric (super 10) Be inventories at the north and south ridgetops are consistent with soil (super 10) Be residence times of 10.5 + or - 3 ky and 9.1 + or - 2 ky, and with steady lowering rates of approximately 16 m/My and approximately 19 m/My, respectively. Increases in meteoric (super 10) Be inventories downslope are consistent with relatively slow creep, with transport velocities of 0.45 cm/y and 0.38 cm/y for the north and south hillslopes, respectively. Comparison of our results with previously-published estimates of regolith production rates inferred from U-series disequilibrium reveals that estimates of steady-state erosion calculated using meteoric (super 10) Be are considerably slower than regolith production rates. We are currently exploring whether this result implies non-steady erosion in the SSHO, or whether it results from differences inherent in the different isotopic techniques. Overall, the meteoric (super 10) Be results suggest that most of the regolith on hillslopes within the SSHO watershed formed during the Holocene since the time of periglacial influence. In turn, estimated erosion rates on the ridgetops may reflect average lowering since that time.

Because the arrival time of seismic phases is a powerful indicator of phase type, we use Bayesloc to probabilistically determine the phase labels for the correlation picks during simultaneous multiple-event location. Bayesloc is a formulation of joint probability over event locations, travel time corrections, phase labels, and arrival-time measurement errors. The Bayesloc formulation is hierarchical with distinct statistical models for each component of the multiple-event system, including prior constraints for any of the parameters. Bayes' Theorem allows calculation of the joint probability for hypothesized configurations of Bayesloc parameters, which facilitates using the Markov-Chain Monte Carlo (MCMC) method to draw samples from the joint probability function. The marginal posteriori distribution for each parameter or covariance between parameters is inferred from MCMC samples. Correlation-based picks are integrated into the Bayesloc formulation by including a new category of arrival time measurement that is derived from correlation of empirical waveforms. Because relative picks are derived from correlation between two waveforms and absolute-time picks are made by analysis of a single waveform--typically an analyst--error processes for relative and absolute arrival time measurements are modeled independently. Relative pick precision is formulated as a function of correlation coefficient and the time-bandwidth product of the correlated waveforms, and absolute arrival times precision--as described in previous work--is formulated as a function phase type, the station, and the individual event. We adopt widely used methodologies for computing differential times based on waveform cross correlation. We first collect all waveforms for a given station and event cluster. A user-specified, phase-specific bandpass filter is applied to each waveform and the phase window is cut from the seismogram based on either analyst picks or a theoretical arrival time. We then compute and save the Fourier transform of each phase-windowed seismogram. Complex multiplication in the frequency domain is used to compute auto correlation and cross correlation spectra. Cross correlation spectra are inverse transformed and normalized based on the average of the autocorrelation amplitudes to produce a normalized, time-domain correlation function. The correlation coefficient is the peak of the correlation function and the time shift is the offset of the peak from the center of the correlation function. The time shift and the correlation coefficient are refined by fitting a parabolic function to the sample points in the neighborhood of the peak in the time-domain correlation function, which allows sub-sample precision for the correlation pick. The difference in time between the arrivals is computed by differencing the start time of the phase windows and adding the correlation-based time shift.

Oblique divergence between the Sierra and the western Cordillera results in an overall pattern of dextral shear and northwest-directed extension in the eastern California shear zone (ECSZ) and southern Walker Lane belt. Within the nominally rigid southern Sierra Nevada block, newly recognized active normal faulting, as well as seismicity, indicate primarily extensional deformation beneath the high topography of the southern range. Investigations of the northern Kern Canyon fault, the Little Lake fault, and the Sierra Nevada range-front faults in Rose Valley combine data from both aerial and ground-based laser scanning, paleoseismic trenching, geologic and geomorphic mapping, and surface exposure dating to define spatial and temporal patterns of fault slip. Taken together, these studies indicate that deformation kinematics along the southeastern Sierran escarpment undergo a pronounced shift at an approximate latitude of 36.5 degrees N. To the north in Owens Valley, range-front faults accommodate active extension and normal faulting, while the adjacent Owens Valley fault displays primarily dextral strike-slip motion. South of Lone Pine, however, a component of active normal faulting steps westward into the southern Sierra Nevada block to the Kern Canyon fault, while range-front faults in Rose Valley accommodate a significant component of oblique dextral extension. Focal mechanism inversion of earthquakes in the southern Sierra Nevada reveals a zone of horizontal extension and vertical crustal thinning coincident with this westward shift of normal faulting into the range. The zone of extension is directly east of the "Isabella Anomaly," a zone of anomalous high P-wave mantle velocities thought to reflect convectively downwelling or foundering lower Sierran lithosphere below the Central Valley. As such, we hypothesize that localized stresses associated with foundering lithosphere, and possibly upwelling asthenosphere, interact with far-field tectonic forces to control patterns of upper crustal faulting both within and along the eastern boundary of the southernmost Sierra Nevada.

Thermodynamic expressions used to constrain the metal-silicate partitioning behavior of siderophile elements are mainly established from large volume press experiments that do not cover the full range of potential P-T conditions for core-mantle equilibrium. The diamond anvil cell is the only static technique capable of achieving required P-T conditions but until now its capabilities to perform quantitative metal-silicate partitioning experiments at extreme conditions has been untapped. We use protocols that effectively link high P-T diamond anvil cell with analytical techniques such as focused ion beam device (FIB); NanoSIMS; electron microprobe; transmission electron microscopes; and in-situ synchrotron X-ray diffraction measurements allow us to obtain quantitative data on element partitioning at superliquidus conditions above 30 GPa and 3000 K. Here we present our advances in both experimental and analytical methods. We look at the partitioning of 6 siderophile elements (Ni, Co, Cr, V, Mn, and Nb) that have been extensively studied at lower P-T conditions and constrain the solubility of light elements (Si and O) at these extreme conditions. We then update expressions that describe the partitioning behavior of these elements to address the validity of proposed core formation models (i.e. single-stage core formation model and continuous core formation model).

Whereas conventional probabilistic seismic hazard and risk analysis (PSHA, PSRA) methods provide an overall framework, they require adaptation to address specific characteristics of induced earthquake occurrence and ground motion estimation, and the nature of the resulting risk. The first problem is to predict the earthquake frequency-magnitude distribution of induced events for PSHA required at the design and permitting stage before the start of injection, when an appropriate earthquake catalog clearly does not exist. Furthermore, observations and theory show that the occurrence of earthquakes induced by an evolving pore-pressure field is time-dependent, and hence does not conform to the assumption of Poissonian behavior in conventional PSHA. We present an approach to this problem based on generation of an induced seismicity catalog using numerical simulation of pressure-induced shear failure in a model of the geologic structure and stress regime in and surrounding the reservoir. The model is based on available measurements of site-specific in-situ properties as well as generic earthquake source parameters. We also discuss semi-empirical analysis to sequentially update hazard and risk estimates for input to management and mitigation strategies using earthquake data recorded during and after injection. The second important difference from conventional PSRA is that in addition to potentially damaging ground motions a significant risk associated with induce seismicity in general is the perceived nuisance caused in nearby communities by small, local felt earthquakes, which in general occur relatively frequently. Including these small, usually shallow earthquakes in the hazard analysis requires extending the ground motion frequency band considered to include the high-frequency, short-duration pulses that typically characterized these events. However, the empirical ground motion prediction equations used in conventional PSHA are poorly constrained at the short distances and smaller magnitudes needed to estimate both nuisance and damage risks from nearby shallow earthquakes. Therefore, we adopt a hybrid approach to estimating ground motions at a local, site-specific scale, in which high frequencies are calculated using a stochastic method or empirical Greens functions, if available, and lower frequencies using reflectivity. We also examine the feasibility of using 3D finite difference wave propagation modeling at local field scales. We will demonstrate the complete PSHA approach by presenting preliminary results of an application to a CO2 sequestration site.

Ramp compression is a developing technique that allows materials to be compressed along a quasi-isentropic path and provides the ability to study materials in the solid state to higher pressures than can be achieved with diamond anvil cell or shock wave methods. Iron and magnesium oxide are geologically important materials each representative of one of the two major interior regions (core and mantle) of terrestrial planets. An experimental platform for ramp loading of iron (Fe) and magnesium oxide (MgO), has been established and tested in experiments at the Omega Laser Facility, University of Rochester. Omega is a 60-beam ultraviolet (352 nm) neodymium glass laser which is capable of delivery kilojoules of energy in approximately 10 ns pulses onto targets of a few mm in dimension. In the current experiments, we used a composite ramped laser pulse involving typically 15 beams with total energy of 2.6-3.3 kJ. The laser beams were used to launch spatially planar ramp compression waves into Fe and MgO targets. Each target had four steps that were approximately 5-7 mu m thick. Detection of the ramp wave arrival and its velocity at the free surface of each step was made using a VISAR velocity interferometer. Through the use of Lagrangian analysis on the measured wave profiles, stress-density states in iron and magnesium oxide have been determined to pressures of 291 GPa and 260 GPa respectively. For Fe, the alpha -epsilon transition of iron is overdriven by an initial shock pulse of approximately 90.1 GPa followed by ramp compression to the peak pressure. The results will be compared with shock compression and diamond anvil cell data for both materials. We acknowledge the Omega staff at LLE for their assistance, Micro/Nano fabrication laboratory staff at Princeton University and the Target Engineering Team at LLNL for fabrication and metrology of the targets used in these experiments.

In our study, we focus on the Middle East, spanning a region from Turkey to the west and West India to the east. This area represents a complex geologic and tectonic setting with sparse seismic data coverage. This has lead to diverging interpretations of crustal and underlying upper-mantle structure by different research groups, complicating seismic monitoring of the Middle East at regional distances. We evaluated an initial 3D seismic model of this region by computing full waveforms for several regional earthquakes based on a spectral-element method. We measure traveltime and multitaper phase differences between observed broadband data and synthetic seismograms for distinct seismic phases within selected time windows using a recently developed automated measurement algorithm. Based on the remaining misfits, we setup an iterative inversion procedure for a fully numerical 3D seismic tomography approach. In order to improve the initial 3D seismic model, sensitivity to seismic structures of traveltime and multitaper phase measurements for all available seismic network recordings is computed. As this represents a computationally very intensive task, we take advantage of a fully numerical adjoint approach by using the efficient software package SPECFEM3D\ (sub GLOBE) on a dedicated cluster. We show examples of such sensitivity kernels for different seismic events. All these 'event kernels' are then summed, smoothed and further used in a preconditioned conjugate-gradient approach. Thus we iteratively update the 3D seismic model, starting at longer periods between 60s and up to 150s and moving towards shorter periods of 11s. We highlight various improvements in the initial seismic structure during the iterations in order to better fit regional seismic waveforms in the Middle East.

However, little is known for the spin state of iron in melts in the mantle. We have measured the Mossbauer spectra of (Mg (sub 0.8) Fe (sub 0.2) )(Si (sub 0.9) Al (sub 0.1) )O (sub 3) glass up to 93 GPa at 300 K in the diamond-anvil cell at Sector 3 of the APS. At ambient conditions, 64% of iron in the glass has a high quadrupole splitting value (QS=2.2 mm/s) consistent with high-spin Fe (super 2+) and 36% has a low QS value (=0.7 mm/s) consistent with high-spin Fe (super 3+) . The ratio of high QS to low QS populations is unchanged by 6 GPa. The population of the low QS site increases rapidly from 34% to 57% between 6 and 32 GPa, followed by a more gradual increase to 68% between 32 and 93 GPa, indicating that 50% of Fe (super 2+) changes from high QS to low QS in the pressure range. According to recent first-principles calculations, low- or intermediate-spin Fe (super 2+) has QS=0.5 approximately 1.5 approximately mm/s which overlaps with the QS of high-spin Fe (super 3+) . Therefore, the increase in the low QS site population can be related to a decrease in the spin moment of 50% of Fe (super 2+) between 6 and 93 GPa. If our findings are applicable for silicate melts, the spin transition in silicate melts may occur over a much wider depth range (200-2500 km) starting at a much shallow depth (200 km) than those in perovskite and ferropericlase in the mantle.

However, the seismic community is far from a consensus due to the inability of properly isolating out the relevant source parameters and varied results, even for the same datasets. Traditional approaches are nearly always hampered by insufficient knowledge of frequency-dependent path and site effects, which the recorded ground motions need to be corrected for in order to derive the source characteristics. To avoid these problems, Empirical Green's Functions (EGF) approaches are a commonly used alternative, which however restricts the useable events to approximately co-located large and small earthquakes with similar source mechanisms. The coda ratio methodology (Mayeda et al., 2007) allows for the inclusion of more events and relaxes the restriction on having the same focal mechanism and is significantly more stable. The current study focuses specifically on a number of selected moderate-sized Japan sequences using a direct wave inversion method (Oth, 2010) and the coda ratio technique. One of the primary goals of the study is to understand the sources of error and compare/contrast the results. Significant breaks in self-similarity are most commonly seen in such studies based on individual sequences, and whether these represent a more general behavior, i.e., also apply to small and large events not necessarily belonging to the same sequence, remains an unclear issue. Recently a country wide study showed no evidence of a scaling break, though the results indicated that individual earthquake sequences can show significant deviations from self-similarity, and that these deviations are closely related to the dominant faulting mechanism of the sequence.

Despite advances in techniques that quantify geologic processes, understanding these processes at a continental scale remains challenging. The South American Andes are an example of a long-lived, morphologically and tectonically segmented orogen. The Northern Peruvian Andes are characterized by flat slab subduction and a relatively narrow section of high topography, in contrast to the central Andes, which contain the broad Altiplano-Puna plateau and normal-angle subduction. Current models of Andean orogenesis suggest that most of the high topography evolved recently beginning about 10-20 Ma. Recent data from the Central Andes further suggest that this uplift occurred rapidly from nearly equal 6-10 Ma. However, as many of these data are from the central Andean region, they may not be directly applicable to the entire Andean chain. Therefore, it is critical to investigate areas outside of the central Andean region using similar techniques to test the applicability of these models elsewhere in the Andes. Here, we use low-temperature thermochronology to characterize the shallow crustal cooling history from four sites in the northern Peruvian Andes, across three degrees of latitude (5 degrees S to 8 degrees S). By using both apatite and zircon (U-Th)/He thermochronometers we are able to record rates of crustal exhumation as well as temporal and spatial accelerations and decelerations of exhumation. In contrast to previous studies based on stratigraphical, structural and sedimentological relationships, our preliminary results show no significant exhumation until the Miocene in the Eastern Cordillera of Northern Peru. In general, our results indicate slow exhumation (<0.01 mm/yr) during the Mesozoic and early Cenozoic and record an acceleration of exhumation in the late Miocene to the present, to rates of 0.2-0.5 mm/yr. This regional acceleration signal occurs in field sites in the north (5 degrees S) and the south (8 degrees S) along strike in the Eastern Cordillera. Samples from the Eastern Cordillera are from Paleozoic to Mesozoic metamorphic and plutonic rocks within fold-and-thrust belts that record significant deformation in the Mesozoic through Paleogene, and only minor activity in the late Cenozoic. However, zircon (U-Th)/He cooling ages range from late Paleozoic to Mesozoic, indicating this section of the fold-and-thrust belt remained in the shallow crust during the Mesozoic-to-mid-Cenozoic, until exhumation to the surface beginning in the late Miocene. Additionally, we also see an area of very rapid ( nearly equal 2-5 mm/yr), and perhaps more localized, exhumation since 3 Ma in the northern Cordillera Blanca region. It's likely this recent accelerated exhumation is related to active faults associated with the exhumation of the Cordillera Blanca Batholith as similar ages and rates are observed in this nearby region. In summary, we show two distinct pulses of exhumation occurring in the Northern Peruvian Andes during the Late Miocene-Pliocene; i) a regional acceleration of exhumation at nearly equal 8-10 Ma and ii) a localized acceleration of exhumation in the northern Cordillera Blanca region at nearly equal 3 Ma.

Previous studies indicate an evolution of the system from meteoric to seawater. The inclined 4-inch diameter RN-17B drill core was collected from 2798.5 m to 2808.5 m ( approximately 2555 m below surface) at in situ temperature of approximately 330 degrees C. Samples for this study were obtained from the Iceland Deep Drilling Project (IDDP). The core contains hydrothermally altered rocks of basaltic composition. Hydrothermal alteration ranges from upper greenschist to lower amphibolite grade, dependent on protolith size and composition. Veins in the core grade inward from radial epidote + acicular hornblende + titanite + pyrite, to clearer equant and compositionally zoned epidote vein centers. Felted amphibole replaces hyaloclastite and smaller crystalline clasts within the core, but is absent from the centers of crystalline pillow basalt fragments. Amphibole in vein selvages and vesicle fillings is green and acicular. Electron microprobe analyses of amphibole indicate it spans a compositional range of ferrohornblende through paragasite. The pistacite component (Xps) of vein epidote ranges from 16.5 to 36.7. The Xps component shows both normal and reverse zoning within single epidote crystals across this range, and follows no distinct pattern. Vein epidote adjacent to the wall rock has a higher aluminum concentration than vein centers. This may be due to mobilization of aluminum from plagioclase in the wall rock during albitization. Solutions flowing through open fractures may have lower Al-content and thus precipitate more Fe-rich epidote than those next to the fracture walls. Primary fluid inclusions in epidote range in size from <1 to 10 mu m in diameter. Secondary fluid inclusions are <1 mu m in diameter and not measurable. Calculated fluid inclusion salinities range from 0.5 to 7.6 weight percent NaCl, with lower salinities adjacent to the wall rock and higher salinities in the vein centers. Homogenization temperature (Th) measurements fall into 3 categories: 1) non-homogenizing adjacent to vein walls; 2) inwards of vein wall (Th = 383.6 to 401.5 degrees C); and 3) the vein center (Th = 344.9 to 378.3 degrees C). Laser ablation ICP-MS spot measurements of strontium isotope (87Sr/86Sr) ratios decrease from the vein edges (0.70500) to the vein centers (0.70400). 87Sr/86Sr isotope ratios are overall shifted away from oceanic basalt values towards seawater values. Lower 87Sr/86Sr ratios in the vein centers indicate an evolution of the system to lower water/rock ratios. If this conclusion is correct, lower water/rock ratio may be responsible for salinities greater than seawater in the vein centers following wall rock hydration.

One way to increase this sensitivity and precision is with more efficient ion sources. Thermal ionization mass spectrometry (TIMS), which yields some of the most sensitive and precise isotope ratio data, uses Re or Ta ribbon filaments as ion sources. These generally ionize material with 1kV), but wider cavities and higher extraction potentials increase the cavity's efficiency, while longer cavities do not. The most efficient CIS modeled had a length of nearly equal 3 cm and an inner radius nearly equal 5 mm. As such, a CIS can be fitted to a commercially available mass spectrometer with relative ease.

Most of these carbonate minerals form at low temperatures (0 to 30 degrees C) and consequently are unlikely to have precipitated from aqueous solutions at equilibrium. The non-equilibrium nature of the precipitation process is well illustrated by the experimentally demonstrated precipitation rate-dependence of parameters such as the Ca and O isotopic composition, and the Sr, Mg, and Mn concentrations of calcite. We have been focused on understanding how to predict the magnitude and controls on these kinetic effects using a general transition-state theory approach, as well as models of ion-by-ion growth, molecular dynamics simulations of the desolvation step required for addition of cations to a mineral surface, and further experiments that involve carefully controlled solution compositions and crystal growth rates. Although models have been proposed that invoke diffusion as the primary control on the non-equilibrium aspects of calcite precipitation, it is relatively easy to show that diffusion is not likely to be the primary controlling process. We have focused on understanding the kinetic effects operating at and near the mineral surface, which are undeniably present and important, and appear to be of the correct magnitude and direction to account for observations in both laboratory and natural calcites. The approach we are using is also applicable to higher temperature aqueous precipitation. There are indications from Ca isotopes that similar surface kinetic effects occur at temperatures of 300 to 400 degrees C. Kinetic isotope and trace element effects are critically dependent on molecular exchange rates between the mineral surface and the aqueous solution, and the ratio of these rates to the net crystal growth rate. The challenge is to predict and/or measure these rates, which are dependent in a complex fashion on solution saturation state, cation/anion ratios, ionic strength, and other aspects of solution composition. In effect, trace elements and isotopes can provide a measure of these rates, and the derived rates from available experimental data are broadly compatible with measured calcite dissolution and precipitation rates and their dependence on solution composition. Overall, it appears possible to develop a comprehensive framework for understanding kinetic trace element and isotopic fractionation effects during precipitation of minerals from aqueous solution, and to constrain the important controlling parameters using a combination of experiments and simulations.

A major issue to overcome when characterizing a fractured reservoir is that of data limitation due to accessibility and affordability. Moreover, the ability to map discontinuities in the rock with available geological and geophysical tools tends to decrease particularly as the scale of the discontinuity goes down. Data collected are often reduced to probability distribution functions for predictive modeling and simulation in a stochastic framework such as stochastic discrete fracture network. Stochastic discrete fracture network models enable probabilistic assessment of flow, transport and geomechanical phenomena that are not adequately captured using continuum models. Despite the fundamental uncertainties inherited within the probabilistic reduction of the sparse data collected, very little work has been conducted on quantifying uncertainty on the reduced probabilistic distribution functions. In the current study, we investigate the impact of parameter uncertainties of the distribution functions that characterize discrete fracture networks on the flow, heat and mass transport and geomechanics. Numerical results of first, second and third moments, normalized to a base case scenario, are presented and compared to theoretical results extended from percolation theory.

As an efficient intrusive uncertainty quantification technique, the KLME approach incorporates a Karhunen-Loeve decomposition of the random permeability field and a perturbative and polynomial expansion of the dependent variables (e.g. fluid pressure, contaminant concentration). The resulting model equations include a series of deterministic ADR equations, each of which is similar in form to the original ones. These equations can be solved using an efficient operator splitting method in which advection and dispersion components are computed numerically and the local reaction contributions are evaluated analytically. The mean values and higher spatial moments of the dependent variables (variance, covariance, and cross-variance) can then be calculated readily from the solutions obtained by this scheme, where the higher order moments serve as quantitative measures of uncertainty in the mean solution. As an example, a suite of two-dimensional numerical experiments in a hypothetical heterogeneous system was considered. The model equations included basic first-order reaction, sequential reaction, and parallel reaction terms, and were solved using both the proposed uncertainty quantification method and a conventional Monte Carlo approach as a means to demonstrate the efficiency and accuracy of newer method over the conventional technique.

In use commercially since the 1950's, the technique has been widely lauded, when combined with other techniques, for enabling the development of shale gas resources in the United States, providing a valuable and extensive source of domestic energy. However, the technique has also drawn a degree of notoriety from high-profile incidents involving contamination of drinking water associated with gas extraction operations in the Marcellus Shale region. This work highlights some of the insights on the behavior of subsurface hydraulic fracturing operations that have been derived from field and laboratory observations as well as from numerical simulations. The sensitivity of fracture extent and orientation to parameters such as matrix material heterogeneity, presence and distribution of discontinuities, and stress orientation is of particular interest, and we discuss this in the context of knowledge derived from both observation and simulation. The limitations of these studies will also be addressed in terms of resolution, uncertainty, and assumptions as well as the balance of fidelity to cost, both in computation time (for numerical studies) and equipment/operation cost (for observational studies). We also identify a number of current knowledge gaps and propose alternatives for addressing those gaps. We especially focus on the role of numerical studies for elucidating key concepts and system sensitivities. The problem is inherently multi-scale in both space and time as well as highly coupled hydromechanically, and, in several applications, thermally as well. We will summarize the developments to date in analyzing these systems and present an approach for advancing the capabilities of our models in the short- to long-term and how these advances can help provide solutions to reduce risk and improve efficiency of hydraulic fracturing operations.

One approach to mitigation is to implement farm-scale management plans that reduce nutrient loading to groundwater while sustaining crop yield. While the effect of different management practices on crop yield is easily measured, their effect on groundwater quality has only infrequently been evaluated. Documenting and predicting the impact of management on water quality requires a quantitative assessment of transport (including timescale and mixing) through the vadose and saturated zones. In this study, we measured tritium, helium isotopic composition, and noble gas concentrations in groundwater drawn from monitor wells on several dairies in the Lower San Joaquin Valley and Tulare Lake basin of California's Central Valley in order to predict the timescales on which changes in management may produce observable changes in groundwater quality. These dairies differ in age (from 100 years old), thickness of the vadose zone (from 50 years. Initial tritium (the sum of measured tritium and tritiogenic helium-3) is close to or slightly above precipitation in the calculated recharge year for young samples; and significantly above the precipitation curve for older samples. This pattern is consistent with the use of 20-30 year old groundwater recharged before 1980 for irrigation, and illustrates how irrigation with groundwater can complicate the use of tritium alone for age dating. The presence of radiogenic helium-4 in several samples with measurable tritium provides evidence of mixing between pre-modern and younger groundwater. Groundwater age-depth relationships are complicated, consistent with transient flow patterns in shallow agricultural groundwaters affected by irrigation pumping and recharge. For the multi-level installations in the southern dairies, both depth profiles and re-sampling after significant changes in groundwater elevation emphasize the need to sample groundwater within 3 meters of the water table to obtain "first-encounter" groundwater with a tritium/helium-3 age of less than 5 years, and to use age tracers to identify wells and groundwater conditions suitable for monitoring and assessment of best management practice impacts on underlying groundwater quality.

However, the relevance of colloid-facilitated metal transport is strongly dependent on the kinetics of metal sorption/desorption reactions on colloidal surfaces. Furthermore, in the natural environment, natural organic matter (NOM) is ubiquitous, and mineral surfaces are often not "bare" but naturally coated with NOM. At this point, it is not clear if and how NOM affects Pu interactions with mineral colloids. For instance, organic matter coatings could bind Pu thereby increasing the fraction of sorbed Pu onto colloids, or slowing down Pu desorption kinetics. This would further stabilize Pu associated with mineral particles, and enhance metal mobility. In addition, dissolved fractions of natural organic ligands may influence Pu sorption behavior based on two primary effects: (1) Pu-NOM solution complexation, and (2) NOM-driven control of Pu oxidation states. Both may indirectly affect metal-mineral interactions, as "free" metals, metal-ligand complexes, and various Pu redox species potentially show different metal sorption affinities and kinetics. The primary goal of this study was the experimental characterization of Pu sorption behavior onto goethite colloids in ternary Pu-NOM-mineral colloid systems. In these systems, fulvic acid (FA), is either present in form of organic matter surface coatings or as dissolved organic ligands. Lab-scale metal sorption/desorption experiments were set up under controlled, chemical conditions (2 g/L goethite, PuTot=1E-10 M, FA=0.5, 5, 50 mg/L TOC, pH=4, I=0.01 M NaCl) in order to evaluate Pu sorption/desorption kinetics in (1) the absence of fulvic acid; (2) the presence of pre-equilibrated Pu-FA solution complexes; and (3) the presence of FA coatings on goethite particles. Both, Pu and FA sorption reactions were monitored over time, which allows for a comparison of Pu and FA sorption kinetics, and provides insights into the underlying mechanisms of FA effects on Pu sorption behavior. First results for pre-complexed Pu-FA systems show an increase in the Pu fractions sorbed onto goethite in the presence of fulvic acid relative to binary Pu-goethite controls. Furthermore, in ternary systems the rates of overall metal sorption reactions appear to be faster and very similar to those for FA sorption. The latter suggests the potential formation of ternary Pu-FA surface complexes on goethite, either by direct sorption of Pu-FA solution complexes or after the rapid creation of an initial organic matter surface coating. In this presentation, results will be further compared to Pu sorption behavior in systems with initially FA-coated goethite.

The Delta (super 14) C of the interior ocean is known to vary due to the major reorganization of circulation and CO (sub 2) sequestration associated with glacial to interglacial climate changes. Using benthic and planktonic (super 14) C ages from deep-sea sediment cores from the southwest Pacific, east of New Zealand, we have constructed a composite depth profile of (super 14) C ages from the late glaciation through the early deglaciation. By using regionally widespread tepha layers as independent stratigraphic markers we can estimate atmosphere-ocean Delta (super 14) C differences. Relative to the atmosphere, our estimates of the Delta (super 14) C at intermediate depths (above 1600 m) are broadly consistent with ventilation similar to today. In contrast, the Delta (super 14) C of upper and mid-depth deep water ( approximately 2000-3800 m) at several points between the late glacial and early deglaciation (24-15 ka) indicate a deep water mass with significantly lower Delta (super 14) C than we would expect for a deep circulation similar to today's. The Delta (super 14) C depletions are range from 50-500ppm, with the gradient between deep and intermediate waters both shallower and steeper than today. Below 3800 m, deep water Delta (super 14) C appear less depleted. Benthic-planktonic Delta (super 14) C differences at all depths show greater relative differences than modern, with the largest differences in upper deep waters. The data from these deep Pacific cores may be susceptible to biases from dissolution and/or bioturbation. However, our consistently low Delta (super 14) C estimates of deep water during the late glacial support the hypothesis that there was a (super 14) C-depleted CO (sub 2) rich water mass in the deep Pacific Ocean during the Last Glacial Maximum that was released to the atmosphere through exchange in the Southern Ocean during the deglaciation.

Ventilation changes in the New Zealand region of the Southern Ocean were reconstructed using high-resolution, mono-specific (P. wuellerstorfi), benthic foraminiferal delta 13C from a 6 cores on the New Zealand Margin, spanning 663 to 3836 m water depth. Age models for these cores were determined using tephrastratigraphy and benthic foraminiferal delta 18O. At the Last Glacial Maximum (LGM), the delta 13C difference(Delta delta 13C) between 663 to 2541 m is approximately 1.7ppm. In the Holocene, the deep water delta 13C value is higher, and Delta delta 13C decreases to approximately 1.0ppm, implying that glacial deep waters were less ventilated. In the early deglaciation, during Heinrich Event 1, delta 13C at the site of modern-day Antarctic Intermediate Water (1165 m) was significantly higher suggesting a pulse of newly ventilated water emanated from the Southern Ocean. During the Antarctic Cold Reversal, the Delta delta 13C profile is similar to the LGM, indicating that ventilation slowed, with a return to glacial-like conditions. Enrichment of the water column in delta 13C from 1165 to 3836 m during the Younger Dryas suggests increasing ventilation of deeper water masses, whereas at 663 m, delta 13C decreases, implying reduced formation of Subantarctic Mode Water.

The water quality of a drinking water production well field is determined by the land use in the capture area, geochemistry of the aquifer and the travel time distributions of the production wells. The aim of our study was to project the water quality of the production well field Holten (The Netherlands) based solely on the travel time distributions of the production wells and water quality data from the monitoring network in the vicinity of the well field. The Holten production wells are located in the east of the Netherlands, in sandy ice-pushed ridges. The travel time distributions of 4 shallow production wells (15-45 m below surface) and 3 deep production wells (45-70 m below surface) have been determined by a combination of 85Kr, 3H/3He and 39Ar dating. Sampled groundwater from 9 monitoring wells (27 screens) has been dated with 3H/3He to relate the water quality data to the time of recharge. Water quality data from the monitoring network provided the regional aggregated trend in water quality parameters, related to the time of recharge. These trends generally show an increase in agricultural contamination up to the 1980s, but decreasing concentrations in younger water. The regional aggregated trend of nitrate shows complete denitrification in groundwater older than 15 years. Excess N2 coincides with elevated sulfate concentrations, demonstrating denitrification by pyrite oxidation. The regional aggregated trends from the monitoring wells provided the source input for the water quality prognosis based on the travel time distributions of the production wells. Shallow production wells with a large young component are projected to show water quality improvements in the near future, while production wells with intermediate age distributions respond slower. The three deep wells produce a mixture of groundwater containing both young and very old water. These are projected to show deterioration in water quality in the future, although nitrate concentrations in these wells are kept low by denitrification. To reproduce the historical time series of concentrations in individual pumping wells it appeared crucial to calculate the time-varying travel time distributions using a regional groundwater flow model. The temporal variations in travel time distributions were caused by mutual interference between the wells during expansion of the well field and changes in pumping regimes over the past 40 years. This showed that the 85Kr, 3H/3He and 39Ar age dating of the abstraction wells provided only a snapshot of these dynamic travel time distributions. This snapshot was used to calibrate the travel time distributions of a regional groundwater flow model at the time of age tracer sampling. We conclude that combining 3H/3He dating of the monitoring wells with dynamic travel time distributions from a calibrated groundwater flow model provides a robust water quality prognosis and well vulnerability assessment.

Irrigated row crops such as lettuce and strawberries dominate both land use and water use. Groundwater is the exclusive supply for both irrigation and drinking water. Some irrigation wells and most public water supply wells in the Salinas Valley are constructed to draw water from deep portions of the aquifer system, where contamination by nitrate is less likely than in the shallow portions of the aquifer system. However, a number of wells with top perforations greater than 75 m deep, screened below confining or semi-confining units, have nitrate concentrations greater than the Maximum Contaminant Limit (MCL) of 45 mg/L as NO3-. This study uses nitrate concentrations from several hundred irrigation, drinking water, and monitoring wells (Monterey County Water Resources Agency, 1997), along with tritium-helium groundwater ages acquired at Lawrence Livermore National Laboratory through the State of California Groundwater Monitoring and Assessment (GAMA) program (reported in Kulongoski et al., 2007 and in Moran et al., in press), to identify nitrate "hot spots" in the deep aquifer and to examine possible modes of nitrate transport to the deep aquifer. In addition, observed apparent groundwater ages are compared with the results of transport simulations that use particle tracking and a stochastic-geostatistical framework to incorporate aquifer heterogeneity to determine the distribution of travel times from the water table to each well (Fogg et al., 1999). The combined evidence from nitrate, tritium, tritiogenic 3He, and radiogenic 4He concentrations, reveals complex recharge and flow to the capture zone of the deep drinking water wells. Widespread groundwater pumping for irrigation accelerates vertical groundwater flow such that high nitrate groundwater reaches some deep drinking water wells. Deeper portions of the wells often draw in water that recharged before agricultural activity began in the valley, while some shallower intervals draw in recycled irrigation water which can have a low tritium concentration but high nitrate concentration. The irrigation return water may take a decade or more to reach the water table, given that the vadose zone in some affected areas is more than 30 m deep, but downward migration is likely enhanced by preferential flow paths, plowing, crop removal, and sprinkler irrigation in surrounding fields.

For California, the large database of tritium-helium, noble gas and stable isotope measurements acquired at Lawrence Livermore National Laboratory (LLNL) in support of the State of California Groundwater Ambient Monitoring and Assessment (GAMA) program provides a unique opportunity to assess pre-development groundwater quality. GAMA is administered by the State Water Resources Control Board with USGS and LLNL as technical leads. These data were acquired for the GAMA California Aquifer Susceptibility and Priority Basin projects (http://www.swrcb.ca.gov/gama/; Belitz, 2003, USGS WRIR 03-4166). Groundwater pumped from long-screened wells will have a mixed distribution of travel times since recharge. Model calculations of mixing between tritium-dead recharge water and younger recharge water assuming simple binary, exponential or dispersive age distributions show that, given the historical levels of tritium in precipitation in the pacific coastal region, a threshold of less than 1 pCi/L of tritium is required to ensure that less than 25% of the pumped groundwater recharged after 1950. The low detection limit is necessary because water recharged between 1980 and 1995 contains only 3-4 pCi/L of tritium at present. The use of groundwater for irrigation in agricultural areas can result in recent recharge of tritium-dead water and complicates the identification of pre-development groundwater. Additional parameters including radiogenic helium, stable isotopes, and recharge temperature were studied to confirm the absence of a modern component. Initial results show that pre-development groundwater reflects the various hydrogeochemical settings found in California, providing natural sources of contaminants in drinking water. For example, arsenic is predominantly found in pre- development groundwater, whereas pre-modern groundwater generally contains lower concentrations of uranium than modern groundwater (Jurgens, 2010, GW 6:913). While perchlorate is more often detected (above 0.5 mu g/L) in modern groundwater, it is also detected in pre-development groundwater in several aquifers (Fram, 2011, EST 45:1271). Nitrate in pre-modern groundwater is found at concentrations significantly above the typical background concentrations of 2 mg/L as N (Nolan, 2002, EST 36:2138) in many of the aquifers studied. We conclude that the uncertainties in contaminant source attribution studies of contaminant compounds with both natural and anthropogenic sources can be reduced through a detailed aquifer-scale study of ambient levels in tritium-dead drinking water wells.

This area contains many possible anthropogenic nitrate sources including current and historic agriculture, private septic systems, municipal waste water, and confined animal feeding operations (primarily dairies). In order to better understand the potential contributions of dairy manure derived nitrate to both shallow and deep groundwater, we used a combined chemical, stable isotope, and age-dating approach for water samples collected from a network of shallow groundwater monitoring wells located on seven different dairies, and from a survey of approximately 200 deeper domestic supply wells (used for drinking water and dairy operations). Groundwater from shallow monitoring wells and deep supply wells was collected in two geographic regions. In the northern region, the lower San Joaquin Valley, the water table is shallow (2- 5 m below surface) and therefore considered highly vulnerable to contamination, while in the southern region, the Tulare Lake Basin, the water table is much deeper (20 - 30 m). Mean delta (super 15) N of nitrate in dairy monitoring wells in both the north and south regions was significantly higher than the mean delta (super 15) N measured in the deeper supply wells, and also showed greater variability. Mean delta (super 15) N and delta (super 18) O values measured in the deep supply wells were not significantly different between the north and south regions. Mean nitrate concentrations, delta (super 15) N, and delta (super 18) O were significantly higher in the northern (lower San Joaquin Valley) monitoring wells in comparison to the southern (Tulare Lake Basin) monitoring wells. Nitrate isotope measurements indicated that many of the northern monitoring wells had consistently high contributions of manure-derived nitrate to the shallow groundwater during the 16 month study. Monitoring wells located in relatively new dairies in the south region showed little evidence of manure-derived nitrate, while those located in much older dairies in the south region showed a very wide range of nitrate isotope values, indicating significant nitrate contributions from multiple sources including manure and industrial fertilizer and biological processing effects. Combined nitrate concentration and isotopic data from all the monitoring wells showed very little evidence of significant saturated-zone denitrification. Monitoring well networks within individual dairies showed wide ranges of nitrate concentrations, nitrate isotopic compositions, and geochemical compositions, confirming the heterogeneity of the nitrate loading across dairy facilities and indicating that measurements from any single monitoring well may not be representative of general groundwater quality downgradient of an individual dairy.

The overall plan is to take the popular CRUST2.0 model--a global model of crustal structure with a relatively poor representation of the uppermost mantle--and improve its nominal resolution to 1 degree and extend the model to include lithospheric structure. The new model, LITHO1.0, will be constrained by many different datasets including extremely large new datasets of relatively short period group velocity data. Other data sets include (but are not limited to) compilations of receiver function constraints and active source studies. To date, we have completed the compilation of extremely large global datasets of group velocity for Rayleigh and Love waves from 10mHz to 40mHz using a cluster analysis technique. We have also extended the method to measure phase velocity and are complementing the group velocity with global data sets of longer period phase data that help to constrain deep lithosphere properties. To model these data, we require a starting model for the crust at a nominal resolution of 1 degree. This has been developed by constructing a map of crustal thickness using data from receiver function and active source experiments where available, and by using CRUST2.0 where other constraints are not available. Particular care has been taken to make sure that the locations of sharp changes in crustal thickness are accurately represented. This map is then used as a template to extend CRUST2.0 to 1 degree nominal resolution and to develop starting maps of all crustal properties. We are currently modeling the data using two techniques. The first is a linearized inversion about the 3D crustal starting model. Note that it is important to use local eigenfunctions to compute Frechet derivatives due to the extreme variations in crustal structure. Another technique uses a targeted grid search method. A preliminary model for the crustal part of the model will be presented.

One outstanding case of such major intraplate earthquakes is the 1811-1812 series of events in the New Madrid Seismic Zone (NMSZ). We contend that the origin of some of these enigmatic intraplate events is due to regional variations in the pattern of tectonic stress generated by mantle convective flow acting on the overlying lithosphere and crust. Mantle convection affects the entire surface of the planet, irrespective of the current configuration of surface plate boundaries. In addition, it must be appreciated that plate tectonics is not a 2-D process, because the convective flow that drives the observed horizontal motions of the tectonic plates also drives vertical displacements of the crust across distances as great as 2 to 3 km. This dynamic topography is directly correlated with convection-driven stress field variations in the crust and lithosphere and these stresses can be locally focussed if the mantle rheology below the lithosphere is characterized by sufficiently low viscosities. We have developed global models of convection-driven mantle flow [Forte et al. 2009, 2010] that are based on recent high-resolution 3-D tomography models derived from joint inversions of seismic, geodynamic and mineral physics data [Simmons et al. 2007, 2008, 2010]. These tomography-based mantle convection models also include a full suite of surface geodynamic (postglacial rebound and convection) constraints on the depth-dependent average viscosity of the mantle [Mitrovica & Forte 2004]. Our latest tomography-based and geodynamically-constrained convection calculations reveal that mantle flow under the Central US are driven by density anomalies within the lower mantle associated with the descent of the ancient Farallon Plate and shallow buoyant anomalies in the upper mantle under the eastern US coastal margin. The viscous coupling of this mantle flow to the overlying crust and lithosphere gives rise to a focussed, convergent stress pattern below the NMSZ which is favorably oriented with respect the local fault geometry. In summary, mantle-flow induced surface depression and associated bending stress may be an important and long-lived contributor to (clustered, migrating) seismic activity in the Mississippi Basin, extending from the Great Lakes to the Gulf of Mexico.

The aim of our work was to use detailed pre- and post-experimental x-ray computed tomography (XCMT) imaging, as well as geochemical data, to constrain reactive transport models that predict the evolution of pore space and permeability for geologic storage of CO (sub 2) in enhanced oil recovery (EOR) fields. A total of nine core-flooding experiments were completed, using three distinct rock types (tight limestone, porous dolostone, and evaporite caprock) to represent the range of natural reservoir physical and chemical heterogeneity. Experiments were conducted under 25 MPa confining pressure, 60 degrees C temperature, and elevated salinity conditions, with pCO (sub 2) levels from 0.5-3 MPa. The coupling of intensive characterization with pressure/permeability and solution chemistry measurements provided powerful tools for interpreting and correlating mineral reactions and stability with pre-existing features and heterogeneities. We observed increased carbonate mass transfer rates, stable dissolution fronts, and greater volumes of dissolved minerals for cores with relatively homogeneous pore networks. Samples with more heterogeneous pore size distributions responded with variable mass transfer rates and development of fast transport pathways in regions with preexisting fractures. We infer that the breakthrough of these preferential fluid pathways leads to reductions in available reactive surface area, allowing undersaturated fluids to be transported through the cores despite relatively fast carbonate dissolution kinetics.

Unfortunately, significant science gaps exist in our understanding of the behavior of CO2 storage reservoirs, leading to very large uncertainty bounds. In this work, we examine one key driver of risk: the potential for leakage out of a storage interval along a permeable fault zone. Two key factors complicate this assessment and must be addressed: (1) fault zones are known to exhibit very complicated multiphysics behavior, and (2) direct characterization of the constitutive properties of a fault zone is typically unavailable. In this work, we will present a computational model for the behavior of a leaking fault connecting a saline storage reservoir and a groundwater aquifer. The model includes both full compositional flow behavior, as well as hydromechanical changes leading to a strain-dependent permeability, addressing several key multiphysics couplings. This deterministic fault model is then used within a UQ sampling framework in order to rigorously quantify the sensitivity of the output response to the input model parameters -- that is, brine/CO2 leakage rates as a function of the input constitutive properties and boundary conditions. We will focus on the implications of these sensitivities for cost-effective characterization and monitoring campaigns, as well as for guiding site operations.

Thermal stratification in stream pools has been observed in various environments; stratification generally persists where the buoyancy forces created by a variation in water density, as a function of water temperature, are able to overcome turbulent forces resulting from stream flow. Because the density gradient creates a relatively weak buoyancy force, low flow conditions are generally required in order to overcome the turbulent forces. In some studies, a cold water source in to the pool bottoms can help to increase the density gradient and perpetuate thermal stratification. Our study took place in Long Meadow, Sequoia National Park, California. Long Meadow lies in the Wolverton Creek watershed and is part of the Southern Sierra Critical Zone Observatory. The 1-4 m diameter and 1-2 m deep pools in our study stratified thermally during the day and mixed completely at night. The low gradient of the meadow provided low stream flows. Piezometers in the meadow indicated groundwater discharge into the meadow in the months during which stratification was observed. Radon 222 activity measured in the pools also indicated groundwater influx to the pool bottoms. We used Fluent, a computational fluid dynamics equation solver, to construct a model of one of the observed pools. Initially we attempted to model the physical mechanisms controlling thermal stratification in the pool including stream flow, groundwater discharge, solar radiation, wind speed, and air, stream and ground water temperatures. Ultimately we found the model best agreed with our observed pool temperatures when we considered the light attenuation coefficients as a function of the dissolve organic carbon (DOC) concentration. Elevated DOC concentrations are expected in low stream flow regimes associated with highly organic soils such as a montane meadow. DOC concentrations measured in samples collected from the meadow stream, pools, and ground water wells ranged from 3.09 to 5.25 mg/L. We used a power equation taken from the literature to vary the visible light attenuation with DOC values measured in the meadow system. Light attenuation coefficients determined from measured DOC concentrations ranged from 0.507 m-1 to 0.899 m-1. The results from our modeling efforts indicate that in low flow streams and rivers elevated concentrations of DOC can increase the potential for thermal stratification in stream pools.

Uncertainties associated with aquifer characteristics, material properties, geochemical compositions, leakage rates and other system parameters coupled together in a numerical model can be quantified and reduced through a rigorous uncertainty quantification (UQ) analysis. UQ is defined as the science of quantitative characterization and reduction of uncertainty in applications. We demonstrate a methodology for UQ and risk assessment of the reactive transport system in which CO2 leakage occurs. The risk profile is defined and related to the plume propagation and pH value below the MCL (Maximum Contaminant Level) value. A global sensitivity analysis is conducted to select the most sensitive parameters to the risk profile. Subsequently, a high-resolution reduced order model is developed for the risk profile as a function of those most sensitive parameters.

The method entailed postulating a spatially-correlated mineral distribution, consisting of calcite, dolomite, anhydrite, and K-feldspar, with specified volume fractions and intrinsic dissolution rates, in contact with an ambient brine composition along a 1-D flow path. Multiple forward reactive transport simulations for the column were run (using PHREEQC for this particular application), with simulated changes in brine chemistry compared with controlled test problem output or real field data. A composite likelihood function was calculated for a set of geochemical parameters consisting of pH and the concentrations of Ca (super 2+) , Mg (super 2+) , and Si that serves as potential indicators of dissolution reactions along the flow path. New realizations were proposed by replacing a small contiguous section of the column with a new distribution of minerals, but one which was still spatially correlated with the remainder of the column. Proposed realizations were accepted when the ratio of the composite likelihood function value to that of the prior proposal was greater than that of a random number selected from a uniform distribution between 0 and 1 (the well-known Metropolis-Hastings acceptance criteria). If a proposal was accepted, the modified mineral distribution served as the basis for a new distribution, otherwise the modification was rejected as a non-improvement. Application of the inverse modeling approach to a synthetic problem demonstrated nearly complete recovery of a specified initial mineral distribution (i.e., "synthetic truth") along the flow path, provided that parameter data were utilized across the entire column. Partial recovery of the synthetic truth was still achievable as the amount of data available for inversion were reduced to just the column endpoint, mimicking the typical situation in the field. When applied to brine chemistry data from a 1-km X 1-km test area at the Weyburn-Midale reservoir, the inversion approach identified variations in the amounts of dolomite and calcite available for reaction along the flow path, given simplifying assumptions concerning permeability, pressure gradient, mineral specific surface, and the extent of mixing in the formation. These variations are qualitatively consistent with known compositional variability in mineralogy between the CO (sub 2) injector and monitoring well locations.

For industrial-scale CO (sub 2) injection in saline formations, pressure buildup can limit storage capacity and security. Active CO (sub 2) Reservoir Management (ACRM) combines brine production with CO (sub 2) injection to relieve pressure buildup, increase injectivity, manipulate CO (sub 2) migration, constrain brine leakage, and enable beneficial utilization of produced brine. Therefore, ACRM can be an enabler of carbon capture, utilization, and sequestration (CCUS). Useful products may include freshwater, cooling water, make-up water for pressure support in oil, gas, and geothermal reservoir operations, and geothermal energy production. Implementation barriers to industrial-scale CCS include concerns about (1) CO (sub 2) sequestration security and assurance, (2) pore-space competition with neighboring subsurface activities, (3) CO (sub 2) capture costs, and (4) water-use demands imposed by CCS operations, which is particularly important where water resources are already scarce. CCUS, enabled by ACRM, has the potential of addressing these barriers. Pressure relief from brine production can substantially reduce the driving force for potential CO (sub 2) and brine migration, as well as minimize interference with neighboring subsurface activities. Electricity generated from geothermal energy can offset a portion of the parasitic energy and financial costs of CCS. Produced brine can be used to generate freshwater by desalination technologies, such as RO, provide a source for saltwater cooling systems or be used as make-up water for oil, gas, or geothermal reservoir operations, reducing the consumption of valuable freshwater resources. We examine the impact of brine production on reducing CO (sub 2) and brine leakage. A volumetric balance between injected and produced fluids minimizes the spatial extent of the pressure perturbation, substantially reducing both the Area of Review (AoR) and interactions with neighboring subsurface activities. This will reduce pore-space competition between neighboring subsurface activities, allowing for independent planning, assessment, and permitting. Because post-injection pressure buildup is virtually eliminated, this could have a major impact on post-injection monitoring requirements. Reducing the volume of rock over which brine can migrate may significantly affect site characterization requirements, as well as the impact of parametric and conceptual model uncertainties, such as those related to abandoned wells. ACRM-CCUS has the potential of playing a beneficial role in site-characterization, permitting, and monitoring activities, and in gaining public acceptance.

ERT also shows potential for monitoring CO (sub 2) injections, despite deployment challenges in the deep subsurface. We present results from analog bench-scale experiments aimed at evaluating the ability of ERT to quantify the volume and spatial distribution of a gas injected into a brine-saturated porous medium. We injected measured volumes of gas into translucent chambers filled with quartz sand, lined with electrodes, and saturated with a low resistivity salt solution. Between injections, a CCD camera captured high-resolution images, and an ERT data acquisition system scanned the chamber. Using the CCD images, quantitative visualization techniques resulted in high-resolution measurements of the spatial distribution and saturation of the injected gas. Direct comparison to inverted resistivity fields then provided a quantitative measure of the ability of ERT to estimate the total volume of injected gas and its spatial distribution within the chamber. We present results from two experiments designed to represent different injection scenarios: (A) low injection rate and strong capillary barrier, and (B) high injection rate and weaker capillary barrier. Results show that ERT provides good estimates of the shape, size and location of the primary gas plume, but underestimates gas content and does not detect thin pathways of gas from the injection port or within the overlying capillary barrier. However, ERT measurements did detect a change in saturation within the primary plume caused by leakage through the capillary barrier in (B), demonstrating the potential utility of ERT as a leakage-monitoring tool. Repeated ERT scans during our experiments led to degradation in data quality that corresponded with an increase in measured contact resistance. Decreased data quality over time is clearly a concern for ERT implementation as a long-term monitoring strategy and deserves further study to quantify the mechanisms responsible for the loss of data quality.

It was therefore reasoned that encasing such an anode with base minerals would lead to enhanced mineral dissolution and hence increased hydroxide (base) generation at the cathode, formed in course of splitting water, generating H (sub 2) and OH (super -) . Subsequent exposue of the alkalized solution to CO (sub 2) (e.g., as in air) would lead to absorption of the CO (sub 2) and formation of stable dissolved or solid (bi)carbonates for carbon sequestration. Previously, it has been demonstrated that mineral carbonate encasement of a seawater electrolysis cell anode indeed generated basic solutions in excess of pH 9 that were subsequently neutralized via contact with air CO (sub 2) , increasing the carbon content of the initial seawater by 30% (Rau, G.H. 2008. Environ Sci. Techol. 42, 8935-). To test such a weathering/CO (sub 2) capture scheme using silicate minerals, either powdered wollastonite or ultramafic rock standard (UM-4) was encased around the anode of an electrolysis cell composed of graphite electrodes and a 0.25M Na (sub 2) SO (sub 4) electrolyte solution. After 0.5 to 1.5 hrs of electricity application (3.5Vdc, 5-10mA), the electrolyte pH rose to as much as 11.1 (initial and blank solution pH's <6.6). Subequent bubbling of these basic solutions with air lowered pH by at least 2 units and increased dissolve carbon content (primarily bicarbonate) by as much as 50X that of the blanks. While Ca (super 2+) and Mg (super 2+) concentrations were elevated, these were insufficient to balance the majority of the bicarbonate anions formed in solution. This suggests that in these experiments the silicate minerals acted as a neutralizer of the anolyte acid, H (sub 2) SO (sub 4) , forming mostly insoluble CaSO (sub 4) and MgSO (sub 4) at the anode. This then allowed NaOH normally produced at the cathode to accumulate in solution, in turn reacting with air CO (sub 2) to form NaHCO (sub 3) . Longer electrolysis times and/or alternative electrolyte solutions might allow formation and precipitation of Ca or Mg carbonates. Such electrochemistry might ultimately provide a safe, efficient way to harness the planet's: i) large, off-peak or off-grid renewable electricity potential, ii) abundant basic minerals, and iii) vast natural brine electrolytes for large-scale air CO (sub 2) mitigation and carbon-negative H (sub 2) production.

However, leakage of CO2 from any potential reservoir could seriously compromise the goal of long-term storage. Furthermore leakage of brine could potentially contaminate overlying aquifers. Therefore understanding the likelihood and rate of potential fluid leakage is a key step toward the feasibility of this technology. Faults and fractures are one of the main pathways for fluid (brine or CO2) migration outside of the storage interval. Several methodologies have been generally used to assess the sealing/leaking properties of faults, considering factors such as gauge formation processes, host rock permeability, clay content, diagenesis, in situ stress, etc.. However, it is well known that faults are extremely heterogeneous and their properties vary both spatially and temporally. Furthermore, little in-situ characterization of fault zones exists, leading to very high uncertainties on model input parameters. In this work, we applied a methodology to quantify leakage rates of CO2 or brine through faults from deep saline reservoirs. We combine hydromechanical simulations with uncertainty quantification of geological and geomechanical model parameters to understand the impact of these uncertainties on predicting the magnitude of potential fluid leakage.

Because of their uniqueness, such noble gas signatures can be confirmatory of the nuclear nature of an event while signatures from other important detection methods, such as anomalous seismicity, are generally not. As a result, noble gas detection at a suspected underground nuclear test site is considered to be the most important technique available to inspectors operating under the On-Site-Inspection protocol of the Comprehensive Nuclear Test Ban Treaty. A one-kiloton chemical underground explosion, the Non-Proliferation Experiment (NPE), was carried out at the Nevada Test Site in 1993 and represented the first On-Site-Inspection oriented test of subsurface gas transport with subsequent detection at the surface using soil gas sampling methods. A major conclusion of the experiment was that noble gases from underground nuclear tests have a good possibility of being detected even if the test is well contained. From this experiment and from computer simulations, we have also learned significant lessons about the modes of gas transport to the surface and the importance of careful subsurface sampling to optimize the detected noble gas signature. Understanding transport and sampling processes for a very wide range of geologic and testing scenarios presents significant challenges that we are currently addressing using sensitivity studies, which we attempt to verify using experiments such as the NPE and a new subsurface gas migration experiment that is now being undertaken at the National Center for Nuclear Security.

For the on site inspection monitoring protocol of the Comprehensive Nuclear Test Ban Treaty, the detection of Ar-37 above its background level is therefore an indicator of a nuclear test. However, Ar-37 is also produced in the subsurface due to cosmic-neutron activation of calcium by the (super 40) Ca(n,alpha ) (super 37) Ar reaction. The cosmic-neutron induced production rate of Ar-37 in the subsurface depends on many uncertain parameters, including the calcium content, the depth below ground surface, the geological structure, and other rock/soil properties. It is therefore important to distinguish the cosmic-neutron induced and test relevant Ar-37 transport in fractured rock and soil. The physical model is conceptualized as a deep dual permeability bedrock layer consisting of overlapping fracture and porous matrix continua overlain by a shallow layer of interconnected clay and sand alluvium. In this study supporting a subsurface gas tracer migration experiment at the National Center for Nuclear Security, we use numerical simulation of non-isothermal multi-phase and multi-component transport to investigate gas-component production, release, and transport in this combined fractured rock and clay-sand alluvium system. In addition to the spatial and temporal domain, we extend the modeling to a high-dimensional space including parameters characterized by a range of uncertainties using the PSUADE code, developed at Lawrence Livermore National Laboratory. Using PSUADE, we consider the dependence of the detectability on these uncertain parameters with the goal of understanding how to optimize the detection of an underground nuclear test.

This effort involves work along two thrusts: 1) we are coupling hydrodynamic (non-linear shock) and seismic (linear anelastic) wave propagation codes; and 2) we are investigating the effect of source emplacement conditions on ground motions in the near field due to nonlinearity and comparing with the empirical models. For both thrusts we are modeling explosion motions using GEODYN, a fully three-dimensional Eulerian hydrodynamic code developed at LLNL. This code incorporates many important features for modeling shock waves in geologic materials, including non-linear response (e.g. porosity, tensile failure, yielding), topography, gravity, 3D material heterogeneities and adaptive mesh refinement. The calculation accuracy is well validated with the analytical solutions to the Lamb's problem and to the finite dilatational volume source at depth in a linear elastic medium. In order to propagate full waveform solutions from hydrodynamic simulations to distances where seismic measurements are made we are coupling GEODYN to WPP (LLNL's anelastic finite difference code for seismic wave simulation). Complex motions computed by GEODYN for explosions are recorded on a dense grid spanning the ranges where motions become linear (elastic). These wavefield records are processed and embedded into the WPP domain where they are introduced as a boundary driving source and continue to propagate as elastic waves at much lower numerical cost than with nonlinear GEODYN. The coupling scheme is validated by comparing the analytical, direct GEODYN solutions and WPP solutions to the finite dilatational volume source at depth in a linear elastic medium, and also by comparing the direct GEODYN solutions and WPP solutions to a complex 1kt chemical explosion in nonlinear granite at stations beyond the elastic radius. The excellent agreement of these solutions demonstrates that the capability of the nonlinear GEODYN code, the coupling scheme and the linear elastic code WPP to accurately predict the full waveforms at any location due to underground explosions. Our second thrust of research involves parametric studies of normally buried (contained) explosions using different canonical geologic material models. The materials range from hard rock (granite) to porous rock (sandstone). The yields range from 0.5 to 5kt. The nonlinear code GEODYN is used to calculate the wavefields due to nuclear explosions and chemical explosion and include gravity and lithostatic pressure. The source spectra were derived from motions by calculating the reduced velocity potential beyond the elastic radius. The results show that for hard rock like granite, the source spectra are in good agreement with the Mueller-Murphy (1971) explosion source model but for a weak porous material such as sandstone, the source strengths are greatly reduced relative to the hard rock. The results also show that the chemical explosions are more efficient than nuclear explosions of the equivalent yield in energy transfer into porous rocks than into hard rocks.

The underlying goal of the model is to provide enhanced seismic event location capabilities. Previous versions of LLNL-G3D (versions 1 and 2) provide substantial improvements in event location accuracy via 3-D ray tracing. The latest models are based on approximately 2.7 million P and Pn arrivals that are re-processed using our global multi-event locator known as BayesLoc. Bayesloc is a formulation of the joint probability distribution across multiple-event location parameters, including hypocenters, travel time corrections, pick precision, and phase labels. Modeling the whole multiple-event system results in accurate locations and an internally consistent data set that is ideal for tomography. Our recently developed inversion approach (called Progressive Multi-level Tessellation Inversion or PMTI) captures regional trends and fine details where data warrant. Using PMTI, we model multiple heterogeneity scale lengths without defining parameter grids with variable densities based on some ad hoc criteria. LLNL-G3Dv3 (version 3) is produced with data generated with the BayesLoc procedure, recently modified to account for localized travel time trends via a multiple event clustering technique. We demonstrate the significance of BayesLoc processing, the impact on the resulting tomographic images, and the application of LLNL-G3D to seismic event location.

The near-source data from the first of the Source Physics Experiments (SPE) performed at the Nevada National Security Site showed significant shear wave generation and anisotropic wave propagation roughly corresponding to joint orientation. Common approaches to explain this behavior have relied on numerical calculations to reproduce experimental data by scaling or 'fitting' material models that derive from small samples of intact material with limited success. Here the joint density and orientation in the rock are well characterized and are used to explain the observed anisotropy of wave propagation. The mechanics of the joint response including friction and saturation together with the intact material model, calibrated for the laboratory-scale granite samples collected from the test site, generate waveforms very similar to those observed in the experiment. Incorporation of the discrete nature of the rock mass in the simulations is imperative to understand the experimental data and to build a predictive capability. Evaluation of the overall strength of geologic materials requires careful attention to the joints or cracks within the bulk material. Thus, we also investigate the shear behavior of single granite joints under different normal loads to simulate experiments typically used for rock characterization. The main goal of this investigation is to provide a meaningful set of parameters for multi-scale contact physics implemented in codes that can handle contact. Both dry and saturated joints are considered. Here we show that explicit incorporation of the joints the simulation of the experiments is imperative to reproduce the observed directional variations in the recorded data. The experimental records show that displacements are much higher than expected, which is attributed to water saturated joints determined from the two and three-dimensional simulations by decreasing the effective friction angle. Lowering the friction angle in the simulations also increased the resulting anisotropic wave motion that traveled more readily along paths of joint persistency. Simulation results will be compared to experimental measurements of both radial and non-radial motions from all available SPE experiments.

These events range from magnitude -1 (microseismicity) up to 3.5, for induced seismicity on pre-existing faults. In our approach, we are using seismic data collected at the Salton Sea geothermal field, to improve the current structural model (SCEC CVM4.0 including a 10m resolution topography) and to invert for the moment tensor and source location of the microseismic events. The key here is to refine the velocity model to then precisely invert for the location and mechanism (tensile or shear) of fracture openings. This information is crucial for geothermal reservoir assessment, especially in an unconventional setting where hydrofracturing is used to enhance productivity. The location of pre-existing and formed fractures as well as their type of openings are important elements for strategic decisions. Numerical simulations are performed using a spectral-element method, which contrary to finite-element methods (FEM), uses high degree Lagrange polynomials, allowing the technique to not only handle complex geometries, like the FEM, but also to retain the strength of exponential convergence and accuracy due to the use of high degree polynomials. Finite-frequency sensitivity kernels, used in the non-linear iterative inversions, are calculated based on an adjoint method.

(2009; 2009; 2010) have shown that regional full waveform moment tensor inversion can discriminate isotropic events due to nuclear explosions from other seismic sources such as earthquakes and mine collapses using regional distance data. However, the effect of vanishing traction at the free-surface is a complication that can bias seismic moment tensor inversions for shallow sources. In this study we address the issue of the effect of free-surface vanishing traction on recovering the seismic moment tensor, scalar seismic moment, and explosive yield. Our preliminary results indicate that the vertical dip-slip Green's functions associated with the M (sub xz) and M (sub yz) components are affected by the vanishing traction at the free-surface, and that this leads to biases in the recovered full moment tensor solutions. The amplitude of the Green's functions decrease systematically, but the waveforms look similar over the targeted depth range with little phase distortion. Initial synthetic testing shows a dependence on source depth and signal-to-noise ratio regarding the waveform moment tensor inversion's ability to recover the isotropic moment of a pure explosion source. However, noise and the free-surface has only minor effects on the isotropic moment recovery for a simple explosion model using a grid-search method. We will document the effects of vanishing traction on seismic moment tensor inversions considering differences in seismic velocity structure, particularly the shallow structure less than 1000 m, and investigate the development of a correctional term applied to isotropic scalar moment estimates from full moment tensor inversions, as well as an approach to damp the M (sub xz) and M (sub yz) terms in the inversion process to attempt to minimize the vanishing traction effect and improve the stability of the full moment tensor inversions for shallow sources.

To do this, we use information on subsurface heterogeneity from nuclear test sites to develop 3D models that have the characteristics of the emplacement media for actual nuclear tests. We then run calculations in these structures and compare results with near field, regional and teleseismic data. Since we will never have complete information on the subsurface structure, we do not expect exact matches of the data, but if the heterogeneous characteristics of the media are correct, we expect the characteristics of the calculated data and the variations in the calculated data to be similar to those of the observed data. We particularly want to understand why shear waves are generated by all underground nuclear explosions. We have developed a 3D nonlinear finite element code designed for calculation of explosions in 3D heterogeneous media with well-tested material models and including gravity; and implemented interface codes using the representation theorem that propagate the numerical solution from the source region to regional and teleseismic distances. We performed calculations in the presence of topography and lateral elastic and nonlinear heterogeneities in order to look at the effect these variations cause on explosion-generated seismic waves. Two sets of calculations were performed in these heterogeneous structures, the first with a yield of 0.2 kt, the second with yield of 5 kt, each detonated in a spherical cavity with a radius of 5 meters. Topography is implemented by gradually distributing offsets of the grid from top to bottom and heterogeneities are implemented by setting different material properties from the background properties in different areas. We propagated 3D calculations using the full waveform representation theorem at a local distance of 2.5km, and at a regional distance of 650 km. The results at the local distance show significant tangential motions for the heterogeneous models. For the topographic model the tangential motions are strongly direction dependent and diminish with distance. The surface wave motions are significantly modulated by the topography and lateral heterogeneities whereas the body waves are less affected by the inhomogeneities. We propagate a calculation of a 5 kt explosion at 402 m depth with variable strength across the source region to a distance of 650 km using the representation theorem. There is a strong SH component not present in a uniform strength calculation. The SH component is consistent with a horizontal dipole source, equivalent to a point force, and without a moment tensor representation. This type of source is not generally considered in explosion modeling, and while it must vanish in the long period limit, it can be significant at frequencies of importance to nuclear monitoring. We also perform a specific 3D nonlinear calculation of the Non-Proliferation Experiment (NPE). We previously modeled this event with a two-dimensional axisymmetric calculation. We ran the calculation with 3D topography, using the actual known topography of the site. The results show generation of an SH wave not present in the calculation without topography.

The goal of the SPE is to improve our physical understanding and ability to model explosively generated seismic waves, particularly S-waves. The first SPE explosion (SPE1) consisted of a 100 kg shot at a depth of 60 meters in granite (Climax Stock). The shot was well-recorded by an array of over 150 instruments, including both near-field wave motion measurements as well as far-field seismic measurements. This paper focuses on measurements and modeling of the near-field data, which included triaxial acceleration measurements at eighteen different locations azimuthally distributed around the explosive charge. Three triaxial accelerometers were embedded in each of six vertical boreholes, distributed in two concentric rings around the charge. The inner ring consisted of three equidistant boreholes at a radius of 10 m from the charge, and the outer ring consisted of another three equidistant boreholes at a radius of 20 m. In each borehole, the accelerometers were vertically distributed at depths of 60 m (shot horizon), 50 m and 15 m. Surface accelerations were also recorded along a radial line centered at surface ground zero. A review of the SPE1 data shows that the peak radial velocity as a function of scaled range is consistent with previous nuclear explosion data but exhibits greater variability. The scaled peak radial displacement also exhibits greater variability but the mean values are significantly higher than exhibited in previous nuclear explosion data. These higher displacements were also observed in calculations performed with a constitutive model based on nuclear explosion data in hard rock, but employed a JWL equation of state for the ANFO explosive used in SPE1. The reason for this behavior is believed to be the higher effective ratio of specific heats in the explosion products of the chemical explosive, leading to higher residual cavity pressure. Azimuthal scatter in the velocity data correspond to joint orientation, and as anticipated, the joints appear to be the principal source of observed shear wave generation in the near field. Preliminary modeling of the SPE1 data shows that continuum simulations that do not explicitly account for the effect of joints will not successfully reproduce the observed directional variations in the recorded data. However, 2D and 3D simulations that explicitly account for joints and pre-existing fractures show that a low friction angle, derived with water-filled joints, may account for the observed variation in peak velocity and displacement. Waves appear to propagate more readily in the direction of persistent joints, as opposed to staggered joints. Furthermore, the anisotropy associated with wave propagation seems to be more pronounced when the friction angle was lowered to account for the effect of saturation. Further modeling is being conducted with continued focus on the effect of the presence of joints and their properties on shear wave generation. Simulation results will be compared to experimental measurements of both radial and non-radial motions from the SPE1 event, as well as from planned future SPE explosions.

It is well known that air-blast and seismic amplitudes depend on explosive yield and range. However for explosions near the ground surface the excitation of air-blast overpressure in the atmosphere and seismic motions depends strongly on the height-of-burst (HOB) for above ground or depth-of-burial (DOB, negative HOB) for buried explosions. We report an algorithm for estimating yield and HOB from near-surface explosions by joint inversion of air-blast overpressure and seismic ground motion amplitudes. The HUMBLE REDWOOD series of chemical explosions conducted at Kirtland AFB were explicitly designed to investigate the effect of HOB on air-blast and seismic motions. Analysis of these data indicates that scaled-range and HOB effects separate and provide calibration data for signal behavior with yield, range and HOB. Variation of air-blast measurements with scaled range for above ground explosions is reasonably well fit by reported models. Dependence with scaled HOB is determined with residuals from above ground air-blast models fit to a parameterized curve. Resampling of the data allows estimates of model errors for both scaled range and scaled HOB and is also used to propagate model errors in the inversion. Similar analysis is performed for the dependence of seismic amplitudes with scaled range and scaled HOB. The inversion of air-blast and seismic amplitudes for yield and HOB uses either a grid search or Markov Chain Monte Carlo (MCMC) approach. The algorithm runs very quickly in either case because the forward calculations are algebraic and very efficient for this two-dimensional model space. We show that inversion results obtained with only one data type (air-blast or seismic) are strongly non-unique and often have large bias. However, joint inversion of air-blast and seismic data breaks the trade-offs between yield and HOB and leads to more accurate estimates. We find that uncertainty in the signal model for seismic amplitude variation with range is the strongest contributor to bias in inversion results. The transportability of the method to different geologic emplacement conditions remains to be determined. We have performed hydrodynamic simulations for a range of HOB in different materials (including non-linear behavior) and can report that seismic ground motions are strongly sensitive to material while air-blast amplitudes are relatively insensitive to the material for explosions near the surface. Simulations can predict air-blast time-series very well if atmospheric conditions are known, however seismic ground motions are more difficult to predict due to uncertainties in geologic material models and three-dimensional structure.

The probabilistic seismic hazard analysis (PSHA) framework that is in widespread use to estimate hazard from naturally occurring earthquakes cannot be applied to IS without adaptations to address the differences between induced and natural seismicity. In particular, the normal PSHA assumption of stationary Poissonian statistics to describe seismic event occurrence are often shown to be invalid in engineered systems, as evidenced both by field observations and by theoretical considerations of the time- and space-dependent pore pressure perturbation of the reservoir. Here we discuss a physics-based approach to adapt conventional PSHA to provide the basis for IS risk analysis before the start of injection and to enable risk estimates to be progressively updated as data are gathered during and after injection. For the pre-injection analysis, earthquake frequency-magnitude distributions are generated by a numerical model that explicitly represents the known geologic structure within the vicinity of the reservoir. To illustrate the approach, we focus our analysis on CO (sub 2) sequestration applications. Using a realistic fault geometry, a von Karman spatial distribution of the coefficient of friction is generated along the fault surface using a flexible, hierarchical (quad-tree) representation. The fault geometry is then meshed and a far-field, constant strain rate boundary condition is applied to mimic regional tectonic loading. Pore pressure perturbations are derived from multi-phase simulations of CO (sub 2) plume evolution in the reservoir and used as a source function. The fault geometry, boundary conditions and pore pressure source term are then used in an alternating event-driven, explicit numerical simulation framework to generate the seismic sources and to evolve the stress distribution over the fault plane. In such an approach, the highest observable frequency is limited by the mesh element size. We evaluate parameter sensitivity by sampling multiple model realizations in order to explore reduced order models that enable fast calculation of the system response. The framework as well as the preliminary illustration of its application will be presented along with commentary on the benefits and drawbacks of the approach.

Since the sole purpose of an OSI shall be to clarify whether a nuclear weapon test explosion or any other nuclear explosion has been carried out, inspection activities can be conducted and techniques used in order to collect facts to support findings provided in inspection reports. Passive seismological monitoring, realized by the seismic aftershock monitoring (SAMS) is one of the treaty allowed techniques during an OSI. Effective planning and deployment of SAMS during the early stages of an OSI is required due to the nature of possible events recorded and due to the treaty related constrains on size of inspection area, size of inspection team and length of an inspection. A method, which may help in planning the SAMS deployment is presented. An estimate of aftershock activity due to a theoretical underground nuclear explosion is produced using a simple aftershock rate model (Ford and Walter, 2010). The model is developed with data from the Nevada Test Site and Semipalatinsk Test Site, which we take to represent soft- and hard-rock testing environments, respectively. Estimates of expected magnitude and number of aftershocks are calculated using the models for different testing and inspection scenarios. These estimates can help to plan the SAMS deployment for an OSI by giving a probabilistic assessment of potential aftershocks in the Inspection Area (IA). The aftershock assessment combined with an estimate of the background seismicity in the IA and an empirically-derived map of threshold magnitude for the SAMS network could aid the OSI team in reporting. We tested the hard-rock model to a scenario similar to the 2008 Integrated Field Exercise 2008 deployment in Kazakhstan and produce an estimate of possible recorded aftershock activity.

The first SPE-N explosion (SPE1) consisted of a 100 chemical explosion at a depth of 180 ft (55 m) in granite at the Nevada National Security Site. The shot was well-recorded by a assortment of over 150 instruments, most of which were along 5 radially oriented lines emanating from the shot location. A variety of instruments were deployed, including high-frequency geophones, accelerometers, broadband seismometers, and rotational sensors. Data recovery from the first shot was over 95%. A review of the SPE1 waveforms shows variations with azimuth in both frequency content and amplitudes. Some of the variations correlated closely with known lateral changes in geology. Importantly, the nearest stations, all of which were located on granite, also showed significant variations presumably due to source or structural features imprinted in the wavefield very close to the source. Preliminary modeling of the SPE1 data using a 3D finite-difference code (WPP) and a 3D velocity model showed similarities in both arrival times and overall features at low frequencies. Further modeling will be conducted with emphasis on understanding the generation of shear waves and comparison of data with the synthetics.

Our study region includes the southwestern part of the Caspian basin, the Kura basin, the Lesser and Greater Caucasus mountains, and the East Anatolian and North Iranian plateaus. We used the data from the Eastern Turkey Seismic Experiment network (1999-2001) in addition to the data which was recorded by 26 permanent broadband stations located in eastern Turkey and Azerbaijan during January of 2006 - July of 2008 in order to develop a 3D S-wave velocity model of the regional uppermost mantle. We selected total of 62 teleseismic events with surface wave magnitudes larger than 5.8 and with good signal-to-noise ratio to determine the fundamental mode Rayleigh wave phase velocities at 13 periods between 20 and 143 seconds. The phase velocity maps show a broad low velocity zone beneath East Anatolian and North Iranian plateaus and three high velocity zones located under the eastern part of the Greater Caucasus, the Talesh and Pontides. Furthermore, the regional uppermost mantle appears to be relatively isotropic. We inverted the Rayleigh wave phase velocities to obtain the regional 3D S-wave velocity model (0-350 km). The low velocity zone is observed starting right at the moho down to 150 km, which suggests asthenospheric material underlying a very thin lithosphere of eastern Anatolia where widespread Late Miocene - Quaternary calc-alkaline volcanic products of mantle origin are reported. Eastern Arabia and Black Sea each have lithospheric roots reaching depths of 150 km. The high velocity body beneath the eastern Greater Caucasus and Kura Basin lies at depths below the moho down to 180 km, and apparently represents either a thick lithospheric mantle root or a shallow subducting slab associated with the South Caspian block. The high velocity bodies beneath the Talesh and Pontides are observed below 160 km. We believe that these high velocity bodies represent remnant Neo Tethys slabs that broke off after the initiation of continental collision between Arabia and Eurasia and could serve as an evidence of two subduction zones beneath Pontide and Bitlis arcs during the Neogene.

It has been demonstrated that increased steam production and fluid injection correlates positively with changes in earthquake activity, resulting in thousands of tiny earthquakes each year with events ranging in magnitude up to 4.5. We determine source parameters for the largest of these earthquakes using a regional distance moment tensor method. We invert three-component, complete waveform data from broadband stations of the Berkeley Digital Seismic Network, the Northern California Seismic Network and the USArray deployment (2005-2007) for the complete, six-element moment tensor. Some solutions depart substantially from a pure double-couple with some events having large volumetric components. Care is needed in the assessment of the significance of the non-double-couple terms. We have worked to develop a systematic procedure for the evaluation of aleatoric and epistemic solution uncertainty (e.g. Ford et al., 2009; Ford et al., 2010). We will present the solutions for The Geysers events together with estimates of random errors and systematic errors due to imperfect station coverage and knowledge of the velocity structure, which are needed to compute Green's functions for the inversion. Preliminary results indicate that some events have large isotropic components that appear to be stable and suggestive of fluid or gas involvement during the rupture processes. We are presently incorporating full moment tensor capability in the Berkeley Seismological Laboratory's automatic processing system and analyst interface. This upgrade will enable improved monitoring at The Geysers and volcanically active regions of California.

In conjunction with collaborators in Saudi Arabia, we have obtained new waveform data from stations in the region and have made thousands of additional surface wave dispersion measurements. These measurements are used to create updated Rayleigh and Love wave group velocity maps which have high-resolution over a wide period band. We have also recently completed the development of the Surface Wave Amplitude Processor (SWAP) tool for making high quality measurements of surface wave amplitudes. The amplitude measurements can be used in a tomography for surface wave attenuation. In general, surface wave amplitude measurements are more difficult to make than group velocity dispersion measurements because information about the source amplitude is needed, requiring a moment tensor solution. Having a focal mechanism is also needed to avoid making measurements at radiation nodes, where amplitudes can be contaminated by multi-pathing. Fortunately, dozens of moment tensor solutions have been determined using regional waveform methods, complementing the large number of Global CMT solutions in the region. We will be presenting preliminary surface wave attenuation maps based on the path measurements from stations in Saudi Arabia and nearby countries. The attenuation maps will be compared and contrasted with our dispersion maps and analyzed for information about the attenuation properties of the sediments, crystalline crust, and upper mantle of the Arabian Peninsula.

Mineral physics constraints are incorporated to link seismic velocities and wave speeds with an underlying hypothesis that temperature is the dominant cause of heterogeneities in the non-cratonic mantle. We begin the modeling procedure by defining the likely range of depth-dependent relative heterogeneity ratios from mineral physics compilations (commonly referred to as R values). Within this expected range, we determine the most appropriate set of 1-D R profiles with corrections for cratonic mass depletion and the temperature dependence of Q. A simulated annealing approach is employed to determine scaling factors and involves solving for 9 free parameters with full-scale joint seismic-geodynamic inversions with each step. In the final modeling stage, we solve for 3-D scaling relationships and mantle heterogeneity (P/S velocities and density) simultaneously through a non-linear inversion process revealing structure that cannot be readily attributed to temperature variations. Although compositional variations are necessary to explain the combined dataset, we argue that most of the mantle's "signal" may be attributed to variations in temperature.

Though no subsurface water mass forms there today, it has long been regarded as a location where intermediate or deep water may have formed in the past. During the last deglaciation, intermediate-depth sediments from around the North Pacific margin from Baja California to Japan are dysoxic or laminated, including in the Bering Sea. It is not clear what are the relative roles of several mechanisms that can could have contributed to the oxygen depletion: the intensification of local export production, reduced intermediate water ventilation rate, lower preformed oxygen concentration, or change in the source of intermediate water. With sediment cores that range from 1.0 to 2.2 km water depth, we investigate the ventilation history of the Bering Sea using stable oxygen and carbon isotope and radiocarbon measurements on planktonic and benthic foraminifera. During the Bolling warm period, water at intermediate depths in the Bering Sea were enriched in (super 14) C and (super 13) C. This well-ventilated water mass co-existed with a more intense and expanded oxygen minimum zone, implying that the intense surface ocean productivity that occurred in the subarctic Pacific at this time was responsible for the oxygen depletion. Therefore, dysoxia observed around the rest of the North Pacific margin at this time is associated with better intermediate water ventilation, and a decoupling of oxygen concentrations and ventilation rates.

Building on cores taken in 2003, a new 20-meter core (LEDC10-1) spanning 9ka to 30ka was acquired in 2010. Twenty-one AMS 14C dates, mostly on discrete organic material (e.g. seeds, charcoal), provide an initial age model. On average 1 cm equals 13 years of sedimentation making this new core the highest resolution, most complete glacial-age terrestrial archive yet obtained from CSWNA. We present initial multi-proxy results including magnetic susceptibility, organic and carbonate content, grain size, CN ratios, and delta D plant leaf waxes to infer past climate state and change. The deglacial sequence is characterized by large amplitude hydrologic change: from a very wet full glacial to a dry Holocene. A delta D shift of 100 per mil indicates a dramatic shift in either P:E ratio or changes in storm tracks/moisture sources. Sand % increases from the Holocene into the glacial, which is interpreted to indicate a wetter-than-present glacial climate in CSWNA. High amplitude sand variability at centennial-to-millennial scales also suggests a highly dynamic climate in CSWNA during the last glacial. Comparisons of the Elsinore record of abrupt hydrologic events to high latitude records show coherence with various climate intervals including Heinrich events 2 and 3. We also observe connections to local marine conditions in the Santa Barbara Basin. Future plans include additional dates, grain size, elemental data, compound specific isotope analyses, microfossil identification/counts, and palynology.

In the North Pacific, these events may have been influenced by the circulation of North Pacific Intermediate Water (NPIW), which could have formed in the Bering Sea in the past. To better understand the mechanisms by which these climate events are transmitted across the globe, we use Bering Sea sediment cores from IODP Exp. 323 site U1340 (1294m) on Bowers Ridge to construct high-resolution climate records of the last 70,000 years. We note 15 millennial-scale events at U1340 during MIS 3, identified by low sediment-density peaks. These low density intervals are characterized by better preservation of diatom frustules and several are laminated, similar to sediments in the Santa Barbara Basin and elsewhere in the North Pacific during past rapid climate events. Stable isotope records contain negative peaks in planktonic delta 18O, implying nearly equal 3-4 degrees C warming. This is confirmed by alkenone temperatures, which show nearly equal 5 degrees C warming and maximum temperatures of nearly equal 9 degrees C. Bulk delta 15N across laminations shows dramatic positive peaks with magnitudes of 1.2-2.3ppm, indicating higher nutrient utilization and/or an enhanced source of water with a denitrification signature. Other proxies show changes in productivity, nutrient content, and intermediate water ventilation. Comparison to other records is used to interpret our data in a global context. U1340 also provides one of the first high-resolution intermediate-depth records of subarctic Pacific MIS 3 climate, and provides evidence for increased formation of NPIW during this interval. Our stable isotope records show simultaneous striking changes indicative of a change in water mass characteristics, and confirm the presence of young intermediate water with higher-than-modern oxygen content in the Bering Sea beginning around 46 ka. Our data is compared to other regional records, several of which also imply changes in ventilation over this period. Finally, our record of the deglaciation and Bolling-Allerod (BA) provides high-resolution data of the expression of these events in the Bering Sea. The deglaciation is marked by a large shift in benthic and planktonic delta 18O interpreted as reorganization of regional circulation. The onset of the BA is characterized by rapid warming and an abrupt shift to laminated sediments. delta 15N rises sharply to a maximum of 8.24ppm; such high values cannot be explained by enhanced nutrient utilization alone, and must be indicative of local or regional denitrification. Paired benthic-planktonic radiocarbon dates also allow a discussion of changes in 14C content during this interval. Our data is compared to regional records to frame our understanding of climate change during this period.

To date, much of the work in seismic interferometry has used ambient noise correlation, which isolates the seismic energy between pairs of seismometers. This has resulted in sharp images of the crust and upper mantle, particularly in areas with dense seismic networks. Curtis et al. (2009) demonstrated that we can reverse the geometry of the problem to focus instead on the energy between pairs of earthquakes. The Virtual Seismometer method (VSM) involves correlating the coda of pairs of events recorded at individual stations and then stacking the results over all stations to obtain an estimate of the Green's function between the sources. By effectively replacing each earthquake with a "virtual station" recording all the others, VSM isolates the portion of the data that is sensitive to the source region and significantly improves our ability to see into tectonically active features. VSM is proving to be a powerful method for studying individual earthquakes and the source region. Using this technique, we are able to recover the expected Green's function between pairs of earthquakes, relocate the earthquakes in time and space, measure the source-time function and source magnitude, and finally image the structure along the path between them. Here we investigate the capability of seismic interferometry for geothermal studies. First, we apply ambient noise correlation to dozens of vertical component seismic stations in Southern California with a particular focus on the Salton Sea geothermal fields. We use these correlations to create a 3 dimensional model of the crust in the region. We then apply VSM to well located earthquakes and explosions in the region to determine the scalability of that technique to very small magnitude events recorded by nearby seismic networks. Of particular interest are the highest frequencies and smallest magnitudes the VSM can resolve.

The results of the study provide the first high resolution terrestrial climate record from Southern California that spans this interesting interval in Earth's climate history. The sedimentological observations and proxy results indicate that the depositional and climatic environments of Lake Elsinore changed significantly across the late-Glacial to Holocene transition. Interpretation of the results suggests that the lake was relatively deep during the last glacial period, but then became relatively shallow and less stable near the beginning of the Holocene interglacial. Interpretation of the results also suggests that the Lake Elsinore deglaciation sequence was characterized by two step-wise decreases in precipitation. Here, this two step drying trend is explained by changes in the extent of the North American ice sheet and variations in the intensity of the Atlantic Meridional Overturning Circulation. Together, the latter two forcings acted to modulate the average position of the circumpolar jet stream, the mean latitude of the Intertropical Convergence Zone, and their combined impacts on the Northern Hemisphere winter storm tracks, which determine the annual hydrologic budget of Southern California. A comparison of the Lake Elsinore deglaciation sequence with other regional paleoclimate records shows strong evidence for synchronous hydrologic change between study sites throughout southwestern North America. Additionally, a comparison of the Lake Elsinore record with the Greenland ice core record provides evidence for a coupling between changes in climate over the North Atlantic and Southern California during the late-Glacial to Holocene transition.

Glacial records provide a means to constrain the timing and magnitude of past climate change within the terrestrial realm and can be integrated with other paleoclimate proxies to help elucidate the dynamic interactions, feedbacks, and teleconnections within the climate system. Here we present glacial chronologies from a suite of high-altitude peaks that span the tropical-subtropical central Andes of South America and compare these results to paleoclimatic records derived from marine, lake, landslide, and ice-core archives. The central Andes lie at the transition between humid tropical climates in the north and arid subtropical climates to the south, making the region particularly sensitive to changing precipitation patterns. Previous studies have spurred debate as to whether glacier advance throughout the central Andes was regionally synchronous due to broad-scale climatic forcing or asynchronous due to localized climatic perturbations and whether or not tropical-subtropical glacial chronologies are in phase with Northern Hemisphere ice sheets. Here we show that glacial advance and retreat in the high central Andes was synchronous throughout the last glacial-interglacial transition and was predominantly driven by large-scale shifts in atmospheric circulation and changing patterns of precipitation. The timing of glacial advance coincides with periods of high lake levels on the Puna-Altiplano plateau, increased snow accumulation revealed by tropical ice-cores, and enhanced landslide activity. These data reveal an Early Glacial ice advance and regionally wet conditions prior to nearly equal 22-25 ka followed by a relatively dry period during the Northern Hemisphere glacial maximum ( nearly equal 21 ka). Subsequently, the central Andes experienced a pronounced increase in moisture and a substantial readvance of alpine glaciers from nearly equal 15-17 ka, coincident with Heinrich Event 1. Following this major readvance, glaciers retreated rapidly with a minor advance/standstill during the Younger Dryas/Antarctic cold reversal at nearly equal 11-14 ka. In the arid southern central Andes, glaciers vanished from the high peaks by nearly equal 8-9 ka, whereas in the northern regions, more humid conditions allow glaciers to persist to the present day. We further show that humid conditions and glacial advances in the central Andes are in phase with periods of reduced Atlantic thremohaline circulation and proposed southerly shifts in the mean position of the Inter Tropical Convergence Zone (ITCZ). Although large-scale shifts in the ITCZ may be the dominant source of hydroclimatic variability, we suggest that additional changes in the intensity of the El Nino Southern Oscillation and/or shifts in the annual timing of monsoonal moisture delivery may further amplify (or dampen) the regional impact of global climate change.

The timing of maximum late Holocene Greenland Ice Sheet extent is usually assigned to the Little Ice Age (LIA), although earlier more extensive Neoglacial advances may have occurred. Here we present new 10-Be surface exposure ages from erratic boulders on bedrock just outside of historical moraines deposited during the LIA near Kangerlussuaq, Paamiut and Narsarsuaq in southwest Greenland to date when ice was more extensive than during the LIA. A more extensive Neoglacial advance at nearly equal 2 ka was previously proposed near Kangerlussuaq. Our cosmogenic dates just outside the historical moraine at Kangerlussuaq indicate, however, that ice has been within its historical limit since 6.8+ or -0.1 ka (n=6, 1 std. error), which is similar to recently published age constraints further north in the Disko Bugt region of west Greenland. Near Narsarsuaq in south Greenland, cosmogenic boulder dates indicate that at 1.2+ or -0.2 ka (n=4, 1 std. error), the outlet glacier Kiagtut sermiat was nearly equal 200 m thicker than its historical limit. The timing of thicker ice near Narsarsuaq is likely concurrent with an nearly equal 8 km advance the same outlet glacier relative to the modern ice margin previously inferred from one minimum limiting radiocarbon date of 1.2+ or -0.1 ka (1sigma ). Cosmogenic dates from near Paamiut in southwest Greenland and additional Narsarsuaq dates are forthcoming. The timing of ice thinning and retreat near Narsarsuaq beginning at nearly equal 1.2 ka is concurrent with a switch from the dominance of Arctic- to Atlantic-sourced water masses within southern Greenland fjords, inferred from changes in fjord faunal assemblages. Modern switches in the source of fjord waters are related to variations in the North Atlantic Oscillation (NAO), with a switch from a positive to a negative phase causing the incursion of relatively warm Irminger Current waters around southern Greenland. We hypothesize that similar variations in North Atlantic atmospheric-oceanic circulation at centennial time-scales could have resulted in relatively cold southern Greenland fjord waters prior to nearly equal 1.2 ka during a positive NAO-like state, which forced a more extensive Neoglacial advance in southern Greenland than during the LIA. Conversely, during the LIA, warmer Atlantic waters may have dominated southern Greenland fjords, resulting in less extensive ice. The importance of this effect may have diminished northward up the coast, such that at Kangerlussuaq and further north, temperatures reached Holocene minima and the ice sheet margin its Holocene maximum extent during the LIA.

This lake is the natural, pre-dam lake where present day Big Bear Reservoir is located. A single drive, 4.8 m-long sediment core was extracted from Lower Bear Lake in 2005. We present a 9000 calendar years before present (cal yr BP) paleohydrologic reconstruction. This new multi-proxy record (LOI 550 degrees C, 950 degrees C; C:N ratios, microfossils counts, grain size) is well-dated (22 AMS 14C dates on discrete organic material) and is characterized by variable sedimentology. Our results indicate two major features: 1) a long-term Holocene drying trend as observed elsewhere in CSWNA with an abrupt shift from wetter to drier conditions about 6200; and, 2) nine centennial-to-multi-centennial pluvial events over the past 9000 cal yr BP superimposed on the long term drying trend. Of these nine inferred pluvial intervals, five are considered major based on their combined proxy interpretations: 9300?-8250, 7000-6400, 3350-3000, 850-700, and 500-? cal yr BP. To assess our results in terms of broader, regional paleoclimate records, we compare the timing of the major pluvial intervals at Lower Bear Lake to those identified previously at Lake Elsinore and Tulare Lake. This comparison reveals a similar timing between the three sites and the major pluvials. This temporally and spatially coherent signal indicates that a similar climate forcing acted to increase regional wetness at various times during the past 9000 cal yr BP. As a working hypothesis, we contend that small changes in the dominant patterns of Pacific SSTs modulated atmospheric circulation, thus favoring periods of enhanced atmospheric river storm activity across CSWNA.

Because hydrogen increases olivine-ringwoodite transformation rates, the existence of metastable olivine in the transition would require the subduction of very dry olivine. Our previous work has shown that for San Carlos olivine spheres, hydrated in a piston cylinder with 75 ppm H2O and 300 ppm D2O, ringwoodite-rim growth rates are greatly enhanced relative to anhydrous samples (Du Frane 2010 and Diedrich et al, 2009). In anhydrous samples, rim-growth rates decrease with time as elastic strain builds up in the system, eventually stopping the reaction. As strain increases, wadsleyite forms, rather than or in addition to ringwoodite. In hydrous samples, hydrogen partitions to the ringwoodite growth rim, hydrolytically weakening it, and preventing the build up of elastic strain energy. Eventually, elastic strain energy may build up in slightly hydrous samples if the hydrogen content of the rim decreases sufficiently. Here we investigate the transformation mechanisms in the same San Carlos olivine samples, hydrated to 75 and 300 ppm H2O and D2O and transformed at 18 GPa. A 75-ppm-H2O sample run at 1100 degrees C for 40 minutes shows a complex mixture of reaction textures. Optical microscopy and Raman spectroscopy show that the ringwoodite rims are nearly pure ringwoodite with minor amounts of wadsleyite. Scanning electron microscopy and transmission electron microscopy on a Focused Ion Beam slices of this sample show that the outermost rim is uniform, relatively course grained and defect free ringwoodite. This suggests limited nucleation at the sample-capsule interface and fairly rapid incoherent growth. The inner rim consists of a complex mixture of olivine and ringwoodite in which most of the ringwoodite has no crystallographic relationship to the host olivine and therefore represents incoherent nucleation and growth. Coherent ringwoodite lamellae are also present in the inner rim and the olivine core. These have the same crystallographic relation to olivine ([001]Ol Rg and (100)Ol {111}Rw) as seen in previous studies (Kershhofer et al 1996). In the core of the olivine spheres, backscatter electron images show thin ringwoodite lamellae and numerous ringwoodite inclusions that are presumably incoherent. Unlike anhydrous samples, which generally contain wadsleyite inclusions, our Raman data indicate that hydrous samples have little intra-crystalline wadsleyite. Some of the ringwoodite inclusions are grouped into linear arrays that suggest heterogeneous nucleation on pre-existing defects such as tilt boundaries. The presence of 75 ppm H2O appears to enhance heterogeneous nucleation and the growth rates of coherent lamellae and incoherent inclusions. These results imply that small amounts of H2O in olivine enhance the transition to ringwoodite by increasing intra-crystalline nucleation and growth rates as well as by increasing rim-growth rates.

To this end, a geochemical nutrient proxy from deep-sea bamboo corals would provide decadal to centennial scale records of deep and intermediate-water nutrient dynamics. Seawater barium (Ba (sub SW) ) has a nutrient-like distribution in the water-column (similar to silicate), so Ba/Ca records in foraminifera, shallow water surface corals, and other deep-sea corals have been used to trace refractory nutrients. Here we present the first calibration of a nutrient proxy from skeletal barium preserved in the calcitic internodes of deep-sea bamboo corals, collected from intermediate water depths. A calibration was calculated from a broadly distributed suite of Isidella and Keratoisis corals spanning a silicate and Ba (sub SW) gradient (n=33 corals; 300-2800 m):Ba/Ca (sub bamboocoral) mu mol/mol=(0.079+ or -0.008)*Ba (sub SW) (nmol/kg) +(4.205+ or -0.87)(r (super 2) =0.77;n=33). The strong linear correlation between Ba/Ca (sub bamboo coral) and Ba (sub SW) suggests that coral Ba/Ca is a reliable recorder of seawater barium (and, therefore, silicate). We find a distribution coefficient (D (sub Ba) ) for Ba/Ca (sub bamboo coral) of 1.3+ or -0.2, similar to that of other corals (surface and deep-sea dwelling) and inorganic calcium carbonate precipitation experiments (D (sub Ba) =1.2-1.5). This suggests that Ba incorporation is primarily driven by cationic substitution in bamboo corals and holds promise as a globally applicable refractory nutrient proxy. We find interannual-decadal scale variability in a Ba/Ca (sub bamboo coral) timeseries from a California Margin coral (San Juan Seamount; 1295 m). These data suggest that additional high-resolution Ba/Ca (sub bamboo coral) records may reveal a connection between regional-scale intermediate water biogeochemistry and low-latitude surface ocean/atmospheric climate.

Several recent studies have demonstrated a positive correlation between short range ordered soil Fe and Al concentrations and soil OM or radiocarbon based residence time. The positive correlation between poorly crystalline Fe and Al and (super 14) C-based residence times suggests that mineral associated OM persists over much longer time scales. Suggested mechanisms include encapsulation within iron oxide microaggregate structures or adsorption to highly reactive metal oxide mineral surfaces both of which have been shown to reduce the bioavailabilty of toxicant species in soil and aquatic environments. We utilized radiocarbon measurements coupled with selective chemical dissolution techniques to investigate the relationship between the concentration of short range order Fe and Al oxides and the stability of soil organic matter across four deciduous forest sites in the eastern U.S.comprising three different soil orders. Preliminary results indicate that SRO Fe and Al slow the turnover of SOM, with a significant linear relationship between computed radiocarbon turnover time and SRO Al and Fe overall (R (super 2) = 0.60,P=0.0001,CL=95%). Piecewise regression analysis on turnover time vs. metal oxide concentration for all four sites shows an apparent metal oxide threshold value at 5g kg (super -1) . Sites with SRO Al and Fe content below this value showed no statistically significant influence on SOM stability presumably because they are present in insufficient quantity to exert a measureable influence on the decomposability of organic inputs. Among individual sites, Harvard Forest had the highest extractable metal oxide concentrations and exhibited the strongest influence of SRO Fe and Al oxides on (super 14) C based turnover times (R (super 2) =0.91, P=0.0001,CL=95%); in this soil, poorly crystalline metal oxides are quantitatively important in stabilizing organic inputs against decomposition. Although more fundamental geochemical research will be necessary to obtain a truly mechanistic description of the specific processes responsible for organic matter stabilization in soil, an empirical approach consisting of selective chemical dissolution coupled with (super 14) C measurements does permit useful insights into the relationship between SOM stability and SRO metal oxide content for the soils under study which may in turn be used to inform model parameterizations.

We have developed a Markov Chain Monte Carlo (MCMC) approach to invert surface displacements measured by InSAR to map the pressure distribution associated with CO2 injection at the In Salah Krechba field, Algeria. The MCMC inversion entails sampling the solution space by proposing a series of trial 3D pressure-plume models. In the case of In Salah, the range of allowable models is constrained by prior information provided by well and geophysical data for the reservoir and possible fluid pathways in the overburden, and injection pressures and volumes. Each trial pressure distribution source is run through a (mathematical) forward model to calculate a set of synthetic surface deformation data. The likelihood that a particular proposal represents the true source is determined from the fit of the calculated data to the InSAR measurements, and those having higher likelihoods are passed to the posterior distribution. This procedure is repeated over typically approximately 104-105 trials until the posterior distribution converges to a stable solution. The solution to each stochastic inversion is in the form of Bayesian posterior probability density function (pdf) over the range of the alternative models that are consistent with the measured data and prior information. Therefore, the solution provides not only the highest likelihood model but also a realistic estimate of the solution uncertainty. Our InSalah work considered three flow model alternatives: 1) The first model assumed that the CO2 saturation and fluid pressure changes were confined to the reservoir; 2) the second model allowed the perturbations to occur also in a damage zone inferred in the lower caprock from 3D seismic surveys; and 3) the third model allowed fluid pressure changes anywhere within the reservoir and overburden. Alternative (2) yielded optimal fits to the data in inversions of InSAR data collected in 2007. The results indicate that pressure changes developed near the injection well and then penetrated into the lower caprock along the postulated damage zone. As in many geophysical inverse problems, inversion of surface displacement data for subsurface sources of deformation is inherently uncertain and non-unique. We will also discuss the approach used to characterize solution uncertainty.

This study focuses on the last deglaciation and reveals that during this period there were significant variations in the outflow, which implies large changes in moisture availability in the Amazon Basin. Aridity in the Amazon Basin seems to occur between 20.5 ka (calendar) to 17.0 ka and 13.6 ka to 11 ka. The second arid period correlates with the start of the Antarctic Cold Reversal and aridity continues throughout the Younger Dryas period. We find that the large-scale trends in Amazon River outflow are dissimilar to high-latitude variability in either hemisphere. Instead high-resolution variations correlate with the delta (super 18) O difference between Greenland and Antarctica ice core temperature records. This suggests a link between Hemispheric temperature gradients and moisture availability over the Amazon. Based on our results and previously published work we present a new testable 'dynamic boundary-monsoon intensity hypothesis', which suggests that tropical moisture is not a simple belt that moves north or south. Rather, the northern and southern boundaries of the South American Summer Monsoon (SASM) are independently dynamic and driven by temperature gradients within their individual hemispheres. The intensity of rainfall within the SASM, however, is driven by precessionally modulated insolation and the resultant convection strength. Combining these two influences produces the dynamic heterogenic changes in the moisture availability observed over tropical South America since the Last Glacial Maximum.

While previous work has focused on a single period of record, we select analysis timescales ranging from 10 to 32 years, and then compare all possible observed TLT trends on each timescale with corresponding multi-model distributions of forced and unforced trends. We use observed estimates of the signal component of TLT changes and model estimates of climate noise to calculate timescale-dependent signal-to-noise ratios (S/N). These ratios are small (less than 1) on the 10-year timescale, increasing to more than 3.9 for 32-year trends. This large change in S/N is primarily due to a decrease in the amplitude of internally generated variability with increasing trend length. Because of the pronounced effect of interannual noise on decadal trends, a multi-model ensemble of anthropogenically-forced simulations displays many 10-year periods with little warming. A single decade of observational TLT data is therefore inadequate for identifying a slowly evolving anthropogenic warming signal. Our results show that temperature records of at least 17 years in length are required for identifying human effects on global-mean tropospheric temperature. JF - Journal of Geophysical Research.

We reacted end member components of a heterolithic sandstone and shale unit that forms the upper section of the In Salah Gas Project carbon storage reservoir in Krechba, Algeria with supercritical CO2, brine, and with/without cement at reservoir conditions to develop experimentally constrained geochemical models for use in reactive transport simulations. : We observe marked changes in solution composition when CO2 reacted with cement, sandstone, and shale components at reservoir conditions. The geochemical model for the reaction of sandstone and shale with CO2 and brine is a simple one in which albite, chlorite, illite and carbonate minerals partially dissolve and boehmite, smectite, and amorphous silica precipitate. The geochemical model for the wellbore environment is also fairly simple, in which alkaline cements and rock react with CO2-rich brines to form an Fe containing calcite, amorphous silica, smectite and boehmite or amorphous Al(OH)3. Our research shows that relatively simple geochemical models can describe the dominant reactions that are likely to occur when CO2 is stored in deep saline aquifers sealed with overlying shale cap rocks, as well as the dominant reactions for cement carbonation at the wellbore interface.

Despite the limited availability of experimental data on this binary system, thermodynamic assessment has been performed and two phase diagrams are proposed that make distinction at high temperature between the relative stability of the bcc phase and the liquid state. Our investigation provides guidance and motivates further experimental studies.

We conducted two benchtop capillary barrier experiments, followed by interpretation and numerical modeling. The hydraulic parameters for two coarse materials were measured using standard methods, and we found that the materials had similar hydraulic properties despite being morphologically different (round vs. angular). The round sand provided a better functioning capillary barrier than the angular sand, but neither experiment could be characterized as a perfectly working capillary barrier. In both cases, >93% of the infiltrating water was successfully diverted from the lower layer; however, infiltration into the underlying layer was observed in both systems. Based on this work, we believe that noncontinuum processes such as vapor diffusion and film flow contribute to the observed phenomena and are important aspects to consider with respect to capillary barrier design as well as dry vadose zone processes in general. Using a theoretical film flow equation that incorporates the surface geometry of the porous material, we found that infiltration into the coarse underlying sand layer appeared to be dominated by water film flow. The NUFT (Nonisothermal Unsaturated-Saturated Flow and Transport) model was used for qualitative comparison simulations. We were able to reproduce the barrier breach observed in the experiments using targeted parameter adjustment, by which pseudo-film flow was successfully simulated.

We evaluate the relevance of these characteristics for neptunium(V) (Np(V)) sorption/desorption on goethite using a 34-day flow-cell experiment and kinetic modeling. Based on experimental results, the Np(V) desorption rate is much slower than the (ad)sorption rate, and appears to decrease over the course of the experiment. The best model fit with a minimum number of fitting parameters was achieved with a multi-reaction model including (1) an equilibrium Freundlich site (site 1), (2) a kinetically-controlled, consecutive, first-order site (site 2), and (3) a parameter psi (sub 2,de) , which characterizes the desorption rate on site 2 based on a concept related to transition state theory (TST). This approach allows us to link differences in adsorption and desorption kinetics to changes in overall reaction pathways, without assuming different adsorption and desorption affinities (hysteresis) or irreversible sorption behavior a priori. Using modeling as a heuristic tool, we determined that aging processes are relevant. However, hysteresis and irreversible sorption behavior can be neglected within the time-frame (desorption over 32 days) and chemical solution conditions evaluated in the flow-cell experiment. In this system, desorption reactions are very slow, but they are not irreversible. Hence, our data do not justify an assumption of irreversible Np(V) sorption to goethite in transport models, which effectively limits the relevance of colloid-facilitated Np(V) transport to near-field environments. However, slow Np(V) desorption behavior may also lead to a continuous contaminant source term when metals are sorbed to bulk mineral phases. Additional long-term experiments are recommended to definitely rule out irreversible Np(V) sorption behavior at very low surface loadings and environmentally-relevant time-scales.

Stochastic inversions, which do provide a sampling-based measure of uncertainty, are computationally expensive and not straightforward to implement for nonexperts (nonstatisticians). Our results include stochastic inversion for magnetotelluric and controlled source electromagnetic data. Two Markov Chain sampling algorithms (Metropolis-Hastings and Slice Sampler) can significantly decrease the computational expense compared to using either sampler alone. The statistics of the stochastic inversion allow for (1) variances that better reveal the measurement sensitivities of the two different electromagnetic techniques than traditional techniques and (2) models defined by the median and modes of parameter probability density functions, which produce amplitude and phase data that are consistent with the observed data. In general, parameter error estimates from the covariance matrix significantly underestimate the true parameter error, whereas the parameter variance derived from Markov chains accurately encompass the error.

X-ray emission spectroscopy and synchrotron Mossbauer spectroscopy reveal a rapid increase in the population of low-spin Fe (super 3+) in Fe (super 3+) , Al-bearing Pv over a narrow pressure range near 70 GPa, which is in sharp contrast with Al-free Fe (super 3+) -bearing Pv, where Fe (super 3+) undergoes a gradual spin transition, and with Al-free Fe (super 2+) -bearing Pv, where Fe (super 2+) does not become low spin. At low pressure, Fe (super 3+) and Al expand the perovskite lattice. However, near the pressure range of the abrupt increase in the low-spin population, the unit-cell volume of Fe (super 3+) , Al-bearing Pv becomes similar to that of Mg-endmember Pv, while those of Al-free Fe (super 3+) -bearing Pv and Al-free Fe (super 2+) -bearing Pv remain larger throughout the lower mantle. Consequently, Pv in Al-rich systems should have lower density in the shallow lower mantle but similar or greater density than Pv in pyrolite in the deep lower mantle, affecting the buoyancy and mechanical stability of heterogeneities. Although the Fe (super 3+) spin transition in Pv is unlikely to cause a seismic discontinuity at mantle temperatures, it may result in a large change in bulk sound speed at 1200-1800 km depth, such that a vertically extending structure with an elevated amount of Fe (super 3+) would generate slower and faster anomalies above and below the depth of the spin transition, respectively, relative to the surrounding mantle. This may have important implications for bulk sound speed anomalies observed at similar depths in seismic tomography studies.

The results from (super 27) Al single pulse magic angle spinning (SP/MAS) and (super 27) Al{ (super 1) H} rotational echo double resonance (REDOR) allow us to identify the reaction products and constrain their structure. In all cases, despite low Al and Si concentrations we observe the formation of metastable aluminosilicates. Results from low temperature experiments indicate that despite thermodynamic driving forces for the formation of gibbsite we observe the precipitation of separate octahedrally coordinated Al (Al (super [6]) ) and tetrahedrally coordinated Al (Al (super [4]) ) silicate phases. At higher temperatures the Al (super [4]) silicate phase dominates the speciation.

To remove any global warming signal present in the data, the traditional definition specifies that monthly-mean, global-average SST anomalies are subtracted from the local anomalies. Differences in the warming rates over the globe and the PDO region may therefore be aliased into the PDO index. Here, we examine the possibility of a human component in the PDO, considering three different definitions. The implications of these definitions are explored using SSTs from both observations and simulations of historical and future climate, all projected onto (definition-dependent) observed PDO patterns. In the twenty first century scenarios, a systematic anthropogenic component is found in all three PDO indices. Under the first definition-in which no warming signal is removed-this component is so large that it is also statistically detectable in the observed PDO. Using the second/traditional definition, this component is also large, and arises primarily from the differential warming rates predicted in the North Pacific and over global oceans. Removing the spatial average SST signal in the PDO region (in the third definition) partially solves this problem, but a human signal persists because the predicted pattern of SST response to human forcing projects strongly onto the PDO pattern. This illustrates the importance of separating internally-generated and externally-forced components in the PDO, and suggests that caution should be exercised in using PDO indices for statistical removal of "natural variability" effects from observational datasets.

Watershed area ranges between 22 km (super 2) and 2560 km (super 2) . Mean watershed elevation ranges from 151 m to 2267 m and mean basin slope was between 5 and 18 degrees. The watersheds stretch from east to west across the country and most include at least some of the mountainous spine of the isthmus. We measured the concentration of in situ produced (super 10) Be in quartz purified from the sand fraction of all samples (250-850 mu g); measured concentrations of (super 10) Be range between 7.61 X 10 (super 3) and 1.37 X 10 (super 5) atoms/g. Erosion rates derived from these concentrations range from approximately 20 m/My to almost 600 m/My, average about 200 m/Myr, and have a median of 100m/Myr. There seems to be no spatial pattern in the distribution of erosion rates along the spine of Panama nor is there any statistically significant relationship between erosion rates and average basin slope, mean basin elevation, or watershed area. To investigate the influence of landslides on the (super 10) Be concentration of stream sediments, we sampled sediment from an active landslide as well as from the river several hundred meters up and downstream of the slide. We split the samples into 7 different grain sizes and measured each grain size separately. The (super 10) Be concentration upstream averaged 2.15 X 10 (super 4) atoms/g; downstream it averaged 1.67 X 10 (super 4) atoms/g; the landslide sediment contained 1.17 X 10 (super 4) atoms/g. Assuming a two-component mixture, it appears that sediment from the landslide makes up about half (49%) of the sediment sampled downstream. We observed an inverse relationship between grain size and (super 10) Be concentration in all three of the samples for which we analyzed multiple grain sizes.

Incision rates of the Colorado River in Grand Canyon generally rely on dating geologic deposits such as lava flows, speleothems, and river gravels that represent the paleo-river elevation divided by the distance to the modern river. Thus, they often provide information about incision integrated over hundreds of thousands to millions of years and assume continual base level lowering. However, only a few studies have investigated the timescale of hillslope response in Grand Canyon tributary basins climatic perturbations and to the base level lowering and of the Colorado River. For example, Anders et al. (2005) found that while tributary drainages are well-linked to sediment sources, tributary basin response lagged Colorado River incision by up to several tens of millennia in eastern Grand Canyon. Using a different approach, we collected samples of fluvial sediment from tributary mouths throughout Grand Canyon. We separated quartz from the sand fraction and measured in situ produced cosmogenic (super 10) Be. The basin-scale data suggest strong correlation between tributary erosion rates and Colorado River incision rates. Basin-scale erosion in the eastern Grand Canyon averages 147 + or - 13 m/My (n=19), integrated over millennia. This rate corresponds with the multiple incision rate data that average approximately 150 m/My in this reach. Similarly, basin-wide erosion rates in western Grand Canyon downstream of the Hurricane and Toroweap faults average 61 + or - 18 m/My (n=4), compared with incision estimates that average approximately 70 m/My in this reach. Our data suggest that tributary hillslope response to Colorado River incision is rapid enough over the effective window of cosmogenic (super 10) Be that tributaries quickly adjust to incision by the Colorado River.

During the last glacial period the lake was much higher, and the physical stratigraphic evidence for lake level fluctuations (Lajoie, 1968, Berkeley Ph.D. thesis) has been linked to changes in carbonate flux in the late Pleistocene Wilson Creek Formation (Zimmerman et al., in press, GSA Bull.). In addition to changes in carbonate, the lake sediments show large variations in leachable Li, Mg, Sr and Ca that correspond to the variations in carbonate. Mono Lake has an unusual chemistry. It is highly alkaline and highly oversaturated with respect to calcite and Mg-smectite (the host mineral for Li), but the aqueous Ca and Mg concentrations are very low, leading to a situation where the amount of precipitation of calcite and Mg-smectite is related to the amount of input of fresh stream and/or spring water into the lake. In order to better understand the controls on precipitation of these authigenic phases, with the goal of developing a highly resolved record of paleo-hydroclimate for the Mono Basin, we are making simple models of the predicted lake chemistry changes based on evaporation and mixing of saline and fresh waters in proportions that approximate the changes in lake level through the last glacial cycle. We have used the PHREEQC model to calculate the stability of mineral phases precipitating out of Mono Lake waters, thus providing insight into the chemical evolution of Mono Lake through the last glacial cycle. The results support our observational evidence, initially counterintuitive, that glacial-age Mono Lake sediments have high carbonate and leachable Li concentrations when lake level is high.

Present chronologies of these changes have focused on large pluvial lakes (e.g., Bonneville, Lahontan, and Mono) within the context of lake level elevation, i.e., meters above sea level. However, assuming precipitation-evaporation is the dominant control on lake level changes, a more appropriate perspective may be through lake volume for the following reasons: 1) due to the intrinsic link between lake volume and basin geometry and 2) the extrinsic influence of basin geometry on evaporation potential. Volumes were calculated using a GIS approach from Mono Basin Digital Elevation Models at 1 m vertical resolution from the basin floor to the highest deglacial lake terrace. The contrast in magnitude between the estimates of lake elevation and volume changes can be demonstrated from Mono Lake, CA. Mono Lake's LGM lowstand to deglacial highstand fluctuation was an approximately 190% rise in elevation (relative to its LGM lowstand). On the other hand, the volumetric increase was approximately 650%. Furthermore, this deglacial high was followed by a dramatic drop in lake level ( approximately 50% in elevation and approximately 250% in volume) at approximately 14.6 ka. Although using elevation to scale lake level changes is simple and straightforward to understand, critical climatic information may be lost by not considering volume. We are working to quantify the volume changes during significant climate events in order to better interpret the implied hydrological changes.

Although different approaches have been applied to establishing the chronology of the Mono Lake sediments, the published radio-isotope results are complicated, and in general the stratigraphic constraints are not directly related to shorelines. We recently discovered a few visually clean, white, shiny, dense carbonate samples that represent a very small fraction of tufa deposits in the Mono Basin. Their very low thorium, but high uranium contents allow precise and reproducible U/Th age determinations. A highly resolved history of a minimum lake level through the last deglaciation can therefore be inferred based on sample locations and their ages. Calcite coating along vertical fractures at Black Point indicates that the lake level already rose to approximately 2098 m asl by approximately 16.8 kyr BP. It climbed to at least approximately 2120 m at approximately 15.4 kyr BP, evidenced by calcite cements on conglomerates from the northwestern slope of the Cowtrack Mountains. There may have been some lake level fluctuations after that, but the level was approximately 2114 m at approximately 14.9-14.6 kyr BP, supported by both tabular carbonate layers and calcite coatings along vertical fractures found at the top of Black Point. Calcite coating samples from thinolitic tufa mounds at different terraces in the northern basin, combined with an erosion surface at approximately 2020 m, indicate a rapid lake level drop from approximately 2114 m to approximately 2007 m in 600 years or less between 14.6 to 14.0 kyr BP. The lake level rose again to approximately 2030 m before 13.0 kyr BP and remained relatively stable through 12.0 kyr BP, followed by a final drop to Holocene conditions. Relative to the present lake level of approximately 1950 m, Mono Lake broadly stood high during Heinrich stadial 1 and Younger Dryas, when the climate was extremely cold over the North Atlantic, and Asian monsoon was much weakened. When the climate shifted from cold to warm during the transition between Heinrich stadial 1 and Bolling-Allerod interstadial, the lake level however dropped significantly by approximately 180 m/kyr. The U/Th ages on the tufa samples therefore not only establish a highly resolved chronology of hydroclimate history in the Mono Basin, but also put the lake level oscillations in a global context.

Geomorphic evidence for lake level changes over the last 2,000 years and during the last glacial period have been extensively described, but lake-level changes from the deglacial through middle Holocene are less well-known. We have recovered a 6.25 m-long core from approximately 3 m of water in the western embayment of Mono Lake, which is shown by initial radiocarbon dates to cover at least the last 10,000 years. Although no terrestrial material for radiocarbon dating was found in the lowermost 3 m of the core, we interpret the light gray, ostracode-bearing silt at the base as recording late glacial or early deglacial time. Black to dark-gray, fine-grained, finely-bedded silts above a disrupted, sand-bearing interval likely indicate a relatively deep lake persisting into the early Holocene, after the initial dramatic regression from late Pleistocene levels. Although further work is required to definitively identify the Holocene ashes, a radiocarbon age of 9905 + or - 215 cal yr BP near the base of the succeeding long sequence of finely-laminated olive-green mud suggests that this is the middle Holocene deep lake of previous cores (Davis, 1999 QR v52, 243-249 and Newton, 1994, SEPM Sp. Pub. 50, p. 143-157). The laminated interval grades into coarser and more colorful sediment, rich in carbonate, indicating a relatively shallower and more variable lake after approximately 5000 years ago. A short interval of olive-green, laminated fine sand/silt just above a radiocarbon date of 3870 + or - 360 cal yr BP may record the Dechambeau Ranch highstand of Stine (1990; PPP v. 78 p. 333-381) at approximately 3800 cal yr BP. This grades into a quite coarse reddish creamy unit, followed by a second finer, more massive interval and a short interval of laminated, organic-rich pea-green mud. A 6 cm-thick ash above the second finer interval is interpreted to be the 1200 year Mono Craters ash because of the coarse lapilli layer in the middle, while a 2 cm-thick ash with coarse lapilli at the base, some approximately 30 cm above the older ash, is likely the 600-year Mono Craters ash. The top of the core is quite coarse, possibly due to the proximity of the coring site to the 1982 A.D. lowstand of 1942 m.

We present here observations made from a field trip in 2007 by two of the authors (SRH and NGH). The towers found above 2030 meters all have abundant thinolite texture, indicating cold water (<6 degrees C) during precipitation of the parent mineral, ikaite, that lasted long enough (seasonally?) to allow replacement of this unstable phase by calcite. In addition to the thinolite texture, centimeter- to decimeter-scale dropstones are observed cemented within the towers, attesting to at least seasonally cold conditions. Previously published radiocarbon ages and elevations of tufa towers (Benson et al., 1990, PPP) found that the highest elevation tufas (above 2070 meters) had a limited range of apparent ages, between 11.8 and 14.1 C-14 kyr BP (six of eight are between 12.0 and 13.4 C-14 kyr BP). We find the relatively limited age range somewhat surprising, though promising. Based on radiocarbon dating of Holocene tufa at Mono Lake, it might be expected that there could be variations of 2000-5000 years in the reservoir (hard water) effect based on variations in the lake and spring waters and the mixtures between them. Additionally, the thinolite texture is quite porous so modern carbon contamination might be expected to be an issue, increasing the possible apparent age range. However, the observed range seems to imply that any complications with the radiocarbon system are limited to hundreds, not thousands, of years. New high precision U-Th ages on the cleanest coatings on tufa towers (Wang et al., this session) combined with radiocarbon measurements on sequentially dissolved tufa shows promise for revealing the variations in reservoir ages in the Pleistocene Mono Basin.

The unit cells of Ice VII and Au were determined by synchrotron X-ray diffraction, using Au as an in situ pressure gauge. All our samples were contained within and chemically insulated from the Re-gasket hole by a gold liner. Measurements of the sound velocity in liquid water have been extended to 8.0 GPa and 873K. We observed, generally, lower velocities (up to 10% at 723 K) than those given by previous studies [1, 2]. The melting of Ice VII was determined by monitoring the sound velocity drop and the disappearance of diffraction pattern of Ice VII upon melting. Our determination of the melting temperatures differ significantly from those given by previous studies [3, 4], with an observed discrepancy of 130 K at 8 GPa. Given the care taken in the present experiments to avoid potential contamination of the water sample due to reactions at high temperatures between the sample and the gaskets and/or pressure gauges, our new measurements likely represent the properties and phase diagram of pure water, which displays an extended stability field of the solid phase. Thus, our new measurements suggest that the melting curve of H (sub 2) O at high pressure needs to be reevaluated. [1] Abramson & Brown (2003) GCA 68, 1827-1835. [2] Decremps et al.

Core locations were targeted with the aid of high resolution CHIRP images collected throughout the lake. We present initial results that include stratigraphic correlation, a preliminary age model based on AMS radiocarbon ages, and some preliminary diatom analyses. Three strong seismic reflectors in CHIRP profiles can be tied to the cores and correlated throughout the southern sub-basin, representing the glacial outwash-post glacial boundary at approximately 10.4 14C kyr BP, the Tsoyowata ash (7950-7730 cal years BP) , and a turbidite representing the most recent seismic event along the West Tahoe-Dollar Point fault (>2484 14C kyr BP). These events, along with other turbidites, are also correlative based on their magnetic susceptibility (MS) peaks and visual identification. The glacial outwash interval shows high MS and is composed of approximately 1.5m of laminated gray-blue clay marking the most recent glacial retreat in the Glen Alpine Valley, southern end of the Tahoe Basin. Preliminary ages from AMS radiocarbon on plant macrofossils indicate that the Holocene-Pleistocene boundary occurs within a 1-3m laminated interval with generally low MS. The laminated interval grades into a discontinuously laminated olive to yellowish-green opaline clay, and is overlain by the 8ka Tsoyowata ash, which is a strong seismic reflector and occurs in all of the cores. The post Tsoyowata package is a 6-8m mottled to faintly laminated green opaline clay. Diatom assemblages are well preserved and dominated by phytoplankton, chiefly A. subarctica and cyclotelloids, with subordinate amounts of araphid pennates. Relative abundance of diatom species vary widely down core, with a large part of the variation attributed to % A. subarctica, and to % periphyton, and show potential for a producing a strong paleoclimate signal. These cores potentially provide a continuous Holocene record of paleolimnologic variations in the Tahoe Basin and paleoclimatic changes in the High Sierra at a decadal to multidecadal scale.

Because of low abundances and the volatility of the (lighter) noble gases, analysis involves specialized sampling in clamped copper tubes and laboratory separation of the noble gases from the abundant atmospheric gases present in groundwater, followed by mass spectrometry. Membrane Inlet Mass Spectrometry (MIMS) systems provide real-time dissolved gas analysis of water flowing across a membrane. The small size and portability of MIMS systems would offer great advantages for fieldwork involving in situ noble gas studies and long-term tracer monitoring. However, with the exception of argon, noble gases have not been measured at atmospheric equilibrium levels in groundwater on a MIMS system so far. We have developed a MIMS capable of measuring the concentrations of noble gases and noble gas isotopes in water samples. The NG-MIMS consists of a membrane inlet, a dry ice water trap, two getters, a turbo pump and a quadrupole mass spectrometer with an electron multiplier. All components are commercially available. The dimensions of the NG-MIMS are 100 X 60 X 40 cm and it weighs about 40 kg. The noble gases are measured at mass-over-charge (m/z) ratios 4 (helium), 22 (neon), 38 (argon), 84 (krypton) and 132 (xenon). The measurement precision of the MIMS at atmospheric equilibrium concentrations is below 2% for helium, argon and krypton and below 3% for neon and xenon. A measurement takes 5 minutes and requires 2.5 ml of water. Various methods of sampling and sample introduction have been studied. Glass vials appear to be sufficient for the containment of the heavier (argon, krypton and xenon) noble gases. Potential applications for the NG-MIMS include active tracer studies in groundwater, fast detection and detailed profiling of radiogenic helium, water column and down-well depth profiling, and the study of excess air formation and noble gas transport at high temporal resolution. In addition, the NG-MIMS provides a much less expensive and less complex alternative for noble gas studies where the high precision of traditional noble gas mass spectrometry systems is not needed. This work was performed under the auspices of the U.S. DOE by LLNL under Contract DE-AC52-07NA27344.

Nuclear power, also a contributor to CO (sub 2) reductions, requires safe and reliable radioactive waste management, which in turn requires sound thermal management of heat-generating waste. The Yucca Mountain Project supported major science and technology advances in unsaturated-zone thermal hydrology, including the development of flow and reactive transport codes, such as TOUGH2, FEHM, and NUFT, as well as modeling approaches, such as the Multiscale Thermohydrologic Model. Resulting validated models were used to support the design of the repository, based on thermal-management principles, as well as support the total system performance assessment. This work is currently being leveraged in science and technology development of geothermal and CCS systems. For industrial-scale CO (sub 2) injection in saline formations, pressure buildup can be the limiting factor in storage capacity and security, while geothermal energy production is often limited by pressure depletion. These two complementary systems can be integrated synergistically, with CO (sub 2) injection providing pressure support to maintain the productivity of geothermal wells, while brine production provides pressure relief and improved injectivity for CO (sub 2) injection wells. Active CO (sub 2) Reservoir Management (ACRM) combines brine production with CO (sub 2) injection to relieve pressure buildup, increase injectivity, manipulate CO (sub 2) migration, constrain brine leakage, and enable beneficial utilization of produced brine. Useful products include freshwater, cooling water, make-up water for oil, gas, and geothermal reservoir operations, and electricity generated from geothermal energy. In addition to reducing costs and risks associated with CO (sub 2) storage, ACRM minimizes interactions with neighboring subsurface activities, which reduces pore-space competition and allows independent assessment and permitting of neighboring subsurface operations. These benefits can help achieve public acceptance. This work performed under the auspices of the U.S. Department of Energy by Lawrence Livermore National Laboratory under Contract DE-AC52-07NA27344.

In order to constrain better the source and character of sediment in the lower meters of the 3053-m long GISP2 ice core (the "silty ice zone"), we measured the concentration of meteoric (super 10) Be, organic carbon, and nitrogen in sediment separated from 17 core samples. The samples represent a total of 3 m of ice including an 11 cm section directly above the bed. Meteoric (super 10) Be is a cosmogenic isotope formed in the atmosphere and delivered to Earth's surface by precipitation and dry fall. It is an excellent tracer of sediment exposed to pedogenic processes; high concentrations of meteoric (super 10) Be are indicative of soil and sediment originating within several meters of Earth's surface. Organic carbon and nitrogen are also markers of soil formation. Silt in the lowermost 6.5 m of the GISP2 ice core has high concentrations of meteoric (super 10) Be (0.6 to 3.8 X 10 (super 8) atoms/g), significant percentages of organic carbon (0.3 to 1.7%), and an average C/N ratio of approximately 10, all consistent with derivation from a well-developed, cold-region soil. The highest concentrations of meteoric (super 10) Be and TOC were measured in the bottom-most ice sample. The (super 10) Be concentration is consistent with a soil inventory > 10 (super 10) atoms/cm (super 2) implying a soil exposure time > 10 (super 5) years before the soil was covered by ice. As Pleistocene interglacial periods were all short (<10 (super 4) year) and few, if any, exposed the bed under GISP2, meteoric (super 10) Be data imply the preservation of soil formed during pre-Quaternary interglacial exposure. Concentrations of meteoric (super 10) Be and total organic carbon co-vary and decrease with distance from the bed, a trend consistent with other data suggesting that the underlying soil is mixed, by ice deformation, with rock flour derived from bedrock erosion elsewhere. The GISP2 core location has likely been ice covered, with the possible exception of a short (4-7 ky) exposure at MIS 11 (Nishiizumi et al., 2006), since 2.5 Mya (Larsen et al., 1994), providing a minimum limiting age for the paleosol underlying Summit, Greenland. The continued existence of this ancient soil indicates extremely low rates of sub-ice erosion at GISP2. Survival of the soil for several million years under the Greenland Ice Sheet is consistent with the ice at Summit having been frozen to the bed for most, if not all, of the Quaternary.

However, there remains a relative paucity of lithosequence studies that directly examine parent material control on pedogenic processes. We sampled a lithosequence of four parent materials (rhyolite, granite, basalt, dolostone/volcanic cinders) under Pinus ponderosa in mesic and ustic soil moisture and temperature regimes of central and southern Arizona, USA to quantify the contribution of parent material to chemical weathering and elemental mass flux. We quantified chemical weathering and mass flux using a combination of quantitative X-ray diffraction and elemental mass balance. Mass flux calculations were confounded by the addition of volcanic cinders in the dolostone soils and addition of eolian materials in both the basalt and dolostone soils. These variations in parent material were accounted for using a combination of refractory element indices and X-ray diffraction. Results indicated significant differences in profile characteristics and chemical weathering among parent materials. Chemical mass loss from the basalt and dolostone soils were balanced or exceeded by addition of eolian materials, leading to positive and highly variable mass fluxes of 14+ or -48 kg m (super -2) and -10+ or -22 kg m (super -2) , respectively. Rhyolite and granite soils exhibited large differences in chemical mass flux despite nearly identical elemental and mineralogical compositions of the respective parent materials. Total chemical mass flux from the granite soils averaged -173+ or -31 kg m (super -2) , whereas mass flux from the rhyolite soils was much larger, on the order of -930+ or -71 kg m (super -2) . These large differences result from the variation of parent material grain size and bulk density. The data demonstrate strong control of parent material on chemical weathering and mass flux in cool, semiarid forested ecosystems.

Groundwater is predominantly modern, or mixtures of modern water, with detectable NO (sub 3) and oxic redox conditions, but some zones have anoxic or mixed redox conditions. Anoxic conditions were associated with long residence times that occurred near the valley trough and in areas of historical groundwater discharge with shallow depth to water. Anoxic conditions also were associated with interactions of shallow, modern groundwater with soils. NO (sub 3) concentrations were significantly lower in anoxic than oxic or mixed redox groundwater, primarily because residence times of anoxic waters exceed the duration of increased pumping and fertilizer use associated with modern agriculture. Effects of redox reactions on NO (sub 3) concentrations were relatively minor. Dissolved N (sub 2) gas data indicated that denitrification has eliminated >5 mg/L NO (sub 3) -N in about 10% of 39 wells. Increasing NO (sub 3) concentrations over time were slightly less prevalent in anoxic than oxic or mixed redox groundwater. Spatial and temporal trends of NO (sub 3) are primarily controlled by water and NO (sub 3) fluxes of modern land use.

Al3509 consists of fine-grained ferroan olivine, ferroan Al-diopside, nepheline, sodalite, and andradite and is crosscut by numerous veins of nepheline, sodalite, and ferroan Al-diopside. Some poorly-characterized phases of fine-grained material are also present; these phases contain no significant H (sub 2) O. The minerals listed above are commonly found in Allende CAIs and chondrules and are attributed to late-stage iron-alkali-halogen metasomatic alteration of primary high-temperature minerals. Textural observations indicate that Al3509 is an igneous object. However, no residual crystals that might be relics of pre-existing CAI or chondrule minerals were identified. To establish the levels of (super 26) Al and (super 36) Cl originally present, (super 26) Al- (super 26) Mg and (super 36) Cl- (super 36) S isotopic systematics in sodalite were investigated. Al3509 shows no evidence of radiogenic (super 26) Mg*, establishing an upper limit of the initial (super 26) Al/ (super 27) Al ratio of 3 x 10 (super -6) . All sodalite grains measured show large but variable excesses of (super 36) S, which, however, do not correlate with the (super 35) Cl/ (super 34) S ratio. If these excesses are due to decay of (super 36) Cl, local redistribution of radiogenic (super 36) S* after (super 36) Cl had decayed is required. The oxygen-isotope pattern in Al3509 is the same as found in secondary minerals resulting from iron-alkali-halogen metasomatic alteration of Allende CAIs and chondrules and in melilite and anorthite of most CAIs in Allende. The oxygen-isotope data suggest that the secondary minerals precipitated from or equilibrated with a fluid of similar oxygen-isotope composition. These observations suggest that the formation of Al3509 and alteration products in CAIs and chondrules in Allende requires a very similar fluid phase, greatly enriched in volatiles (e.g., Na and Cl) and with Delta (super 17) O approximately -3 ppm. We infer that internal heating of planetesimals by (super 26) Al would efficiently transfer volatiles to their outer portions and enhance the formation of volatile-enriched minerals there. We conclude that the site for the production of Na- and Cl-rich fluids responsible for the formation of Al3509 and the alteration of the Allende CAIs and chondrules must have been on a protoplanetary body prior to incorporation into the Allende meteorite. Galactic cosmic rays cannot be the source of the inferred initial (super 36) Cl in Allende. The problem of (super 36) Cl production by solar energetic particle (SEP) bombardment and the possibility that (super 36) Cl and (super 41) Ca might be the product of neutron capture resulting from SEP bombardment of protoplanetary surfaces are discussed. This hypothesis can be tested comparing inferred "initial" (super 36) Cl with neutron fluencies measured on the same samples and on phases showing (super 36) S* by Sm and Gd isotopic measurements.

In order to avoid high costs for disposal, the brines should be processed into useful forms such as fresh and low-hardness water. We have carried out a cost analysis of treatment of typical subsurface saline waters found in sedimentary basins, compared with conventional seawater desalination. We have also accounted for some cost savings by utilization of potential well-head pressures at brine production wells, which may be present in some fields due to CO sub(2) injection, to drive desalination using reverse osmosis. Predicted desalination costs for brines having salinities equal to seawater are about half the cost of conventional seawater desalination when we assume the energy can be obtained from excess pressure at the well head. These costs range from 32 to 40 cents per m super(3) permeate produced. Without well-head energy recovery, the costs are from 60 to 80 cents per m super(3) permeate. These costs do not include the cost of any brine production or brine reinjection wells, or pipelines to the well field, or other site-dependent factors.

Modeling of such flows at micro and macro levels as well establishing relationships between these approaches are needed to understand properties of the particulate matter. We propose a computational technique based on the direct numerical simulation of the particulate flows. The numerical method is based on the distributed Lagrange multiplier technique following the ideas of Glowinski et al. [16] and Patankar [30]. Each particle is explicitly resolved on an Eulerian grid as a separate domain, using solid volume fractions. The fluid equations are solved through the entire computational domain, however, Lagrange multiplier constrains are applied inside the particle domain such that the fluid within any volume associated with a solid particle moves as an incompressible rigid body. Mutual forces for the fluid-particle interactions are internal to the system. Particles interact with the fluid via fluid dynamic equations, resulting in implicit fluid-rigid body coupling relations that produce realistic fluid flow around the particles (i.e., no-slip boundary conditions). The particle-particle interactions are implemented using explicit force-displacement interactions for frictional inelastic particles similar to the DEM method of Cundall et al. [10] with some modifications using a volume of an overlapping region as an input to the contact forces. The method is flexible enough to handle arbitrary particle shapes and size distributions. A parallel implementation of the method is based on the SAMRAI (Structured Adaptive Mesh Refinement Application Infrastructure) library, which allows handling of large amounts of rigid particles and enables local grid refinement. Accuracy and convergence of the presented method has been tested against known solutions for a falling particle as well as by examining fluid flows through stationary particle beds (periodic and cubic packing). To evaluate code performance and validate particle contact physics algorithm, we performed simulations of a representative experiment conducted at the U.C. Berkeley Thermal Hydraulic Lab for pebble flow through a narrow opening.

The method is illustrated on three model problems: a benchmark with known exact solution, groundwater seepage into a dry lysimeter box with time-dependent boundary conditions, and capillary barrier behavior under an intense infiltration. In the second part of the paper we present the weak formulation of the Richards equation for the Newton's and Picard's methods, give a brief overview of adaptive hp-FEM with emphasis on aspects that are usually not discussed in the literature, and we briefly introduce the open source adaptive hp-FEM library HERMES that was used to generate numerical results for this paper.

MPI for Python is a general-purpose Python package that provides bindings for the Message Passing Interface (MPI) standard using any back-end MPI implementation. Its facilities allow parallel Python programs to easily exploit multiple processors using the message passing paradigm. PETSc for Python provides access to the Portable, Extensible Toolkit for Scientific Computation (PETSc) libraries. Its facilities allow sequential and parallel Python applications to exploit state of the art algorithms and data structures readily available in PETSc for the solution of large-scale problems in science and engineering. MPI for Python and PETSc for Python are fully integrated to PETSc-FEM, an MPI and PETSc based parallel, multiphysics, finite elements code developed at CIMEC laboratory. This software infrastructure supports research activities related to simulation of fluid flows with applications ranging from the design of microfluidic devices for biochemical analysis to modeling of large-scale stream/aquifer interactions.

To more accurately capture the singularities in potentiometric head at the wells, the standard linear finite element basis is locally augmented with asymptotic analytical solutions which enable more accurate calculations of leakage rates between aquifers. Highly accurate flux estimates are obtained without the need for higher mesh resolution near wells. Simulations are carried out to test both the accuracy and convergence properties of the XFEM implementation, and the XFEM results are compared to those of a high-resolution standard finite element model. It is seen that for the type of singularity-driven problem posed here, the standard FEM is unable to resolve leakage rates without very fine discretization, but that the XFEM performs robustly with fewer degrees of freedom. The impact of aquifer geometric heterogeneity on leakage rates is assessed and seen to be an important factor in determining total leakage. It is demonstrated that the XFEM may be a valuable tool in many water resources applications where small-scale effects can impact global system behavior. Abstract Copyright (2011) Elsevier, B.V.

Our objective is to separate, as much as possible, subgrid effects induced by the media properties from those due to heterogeneous source terms. For this reason, enriched coarse spaces designed for high-contrast multiscale problems are used to represent the effects of heterogeneities of the media. Furthermore, rough source terms are captured via auxiliary correction equations that appear in the formulation of variational multiscale methods [23]. These auxiliary equations are localized and one can use additive or multiplicative constructions for the subgrid corrections as discussed in the current paper. Our preliminary numerical results show that one can capture the effects due to both spatial heterogeneities in the coefficients (such as permeability field) and source terms (e.g., due to singular well terms) in one iteration. We test the cases for both smooth source terms and rough source terms and show that with the multiplicative correction, the numerical approximations are more accurate compared to the additive correction.

The first approach is based on fundamental solutions in elliptical coordinates and results in products of Mathieu functions. The second approach is based on the integration of modified Bessel functions. Both approaches allow evaluation of the potential at any distance from the element. The computational approaches are applied to model transient flow with the Laplace transform analytic element method. The Laplace domain solution is computed using a combination of point elements and the presented line elements. The time domain solution is obtained through a numerical inversion. Two applications are presented to transient flow fields, which could not be modeled with the Laplace transform analytic element method prior to this work. The first application concerns transient single-aquifer flow to wells near impermeable walls modeled with line-doublets. The second application concerns transient two-aquifer flow to a well near a stream modeled with line-sinks. Abstract Copyright (2011) Elsevier, B.V.

Most numerical multiscale models, which seek to combine these two descriptions, require empirical closures and/or assumptions about the behavior of pore-scale quantities at the continuum (Darcy) scale. We present a general formulation of an iterative hybrid numerical method that links the pore and continuum scales without resorting to such approximations. The algorithm treats the fluxes exchanged at the internal boundaries between pore- and continuum-scale domains as unknown, and allows for iteratively determined boundary conditions to be applied at the pore-scale in order to guarantee flux continuity. While the algorithm proposed is general, we use it to model transport in a fracture with chemically reactive walls. Results demonstrate significant improvement upon standard continuum-scale formulations. Abstract Copyright (2011) Elsevier, B.V.

Our algorithm uses a new method to resample the large-scale (Gaussian-distributed) Fourier modes in a periodic N-body simulation box in a manner that properly accounts for the nonlinear mode coupling between large and small scales. We find that our method for adding new large-scale mode realizations recovers the nonlinear power spectrum to sub-percent accuracy on scales larger than about half the Nyquist frequency of the simulation box. Using 20 N-body simulations, we obtain a power spectrum covariance matrix estimate that matches the estimator from Takahashi et al. (from 5000 simulations) with <20% errors in all matrix elements. Comparing the rates of convergence, we determine that our algorithm requires ~8 times fewer simulations to achieve a given error tolerance in estimates of the power spectrum covariance matrix. The degree of success of our algorithm indicates that we understand the main physical processes that give rise to the correlations in the matter power spectrum. Namely, the large-scale Fourier modes modulate both the degree of structure growth through the variation in the effective local matter density and also the spatial frequency of small-scale perturbations through large-scale displacements. We expect our algorithm to be useful for noise modeling when constraining cosmological parameters from weak lensing (cosmic shear) and galaxy surveys, rescaling summary statistics of N-body simulations for new cosmological parameter values, and any applications where the influence of Fourier modes larger than the simulation size must be accounted for.

The mean-field rate theory (RT) approach has been and remains the standard method for calculations of the kinetics of damage accumulation under irradiation. Despite its many advantages, when using RT, very large numbers of ordinary differential equations (ODEs) need to be solved if one is interested in the kinetics of complex defect populations containing defect clusters made up of constituent defect species of different types, e.g. He, H, O, alloying impurities, etc. Here we present a stochastic variant of RT, which we term stochastic cluster dynamics (SCD), intended as an alternative to the standard ODE-based implementation. SCD obviates the need to solve the exceedingly large sets of ODEs and relies instead on sparse stochastic sampling from the underlying kinetic Master Equation. The new method evolves an integer-valued defect population in a finite material volume. In this paper we describe the general ideas behind the SCD method, give essential details of our numerical implementation and present SCD simulations that verify the new method against standard RT implementations on two well characterized material models. We then apply the method to simulate triple beam irradiation experiments of heavy Fe ions, He, and H on model ferritic alloys up to a dose of 1 dpa.

Validation of this mechanism requires experimental measurement of fission-gas bubble-size distributions at well-controlled gas concentrations and temperatures. There are advantages to carrying out such a study using ion implantation as the source of gas atoms compared with neutron irradiations. In spite of previous successes using ion implantation to study fission-gas behavior in oxide fuels, there is significant uncertainty about the efficacy of using ion beams for metallic fuel studies. To address the question of the applicability of ion beams in experiments designed to study fission-gas behavior in metallic fuels, we developed and applied an exact model for the redistribution of implanted ions under annealing conditions. The conclusion is that, given the assumptions, the results from implantations at 1 MeV or less may be overwhelmed by the surface effects at all relevant temperatures. Implanting at 10 or 80 MeV can significantly diminish the influence of the surfaces and the steep concentration gradients. At 80 MeV, the location of the peak concentration profile remains stable with annealing time. Thus, it appears that ion implantation can be an appropriate tool to study the size distribution of Xe bubbles in metallic fuels.

Increasingly available attenuation models can be used to refine the expected ground motions. First, some tests are performed to look at the effect of the variability in several parameters, such as crustal attenuation, upper mantle attenuation, and crustal thickness. A concrete example is then provided using the results of a recent crust and upper mantle attenuation model of the Middle East. Variations in 1 Hz spectral accelerations of 30%-40% are found simply from the same event recorded in different directions. Because overall regional variability is expected to be even higher, this effect seems significant enough to be accounted for in strong ground-motion estimates and seismic-hazard assessment. This has the potential to account for some of the smaller scale amplitude variations not considered using broadly applied 1D attenuation relationships.

Pg is widely used in source discrimination, but its attenuation behavior is not well understood. We investigate the functional form of the geometrical spreading of Pg for both uniform and more complex seismic velocity structures. We find that there is significant trade-off between attenuation and geometrical spreading of Pg, and we quantify this trade-off to interpret the observed Pg attenuation in the Middle East. The northern Middle East attenuation tomographic images show significant lateral Q (sub Pg) variations, which may be caused by lateral variations of crustal rheology if intrinsic attenuation dominates the seismic attenuation mechanism of this region. We observe very large variations in the Q (sub Pg) model, such as low Q (sub Pg) within the Anatolian plate and high Q (sub Pg) within much of the stable Arabian plate. The low Q (sub Pg) anomalies generally coincide with active fault systems or Quaternary volcanisms. In order to perform a systematic comparison with Lg propagation, we have also updated the Q (sub Lg) map of Zor et al. (2007). These two new maps provide estimates for crustal Q (sub alpha ) (Pg) and Q (sub beta ) (Lg) for the northern Middle East.

Lithospheric structure is obtained by jointly inverting receiver functions and Rayleigh wave group velocities derived from continental-scale surface wave tomography of Pasyanos. We observe relatively thick crust (40-48 km) within the ophiolite formed mountains in northern Oman. The crustal thickness is about 35 km within the passive continental margin of the southern Oman region. Uppermost (<5 km) crustal shear wave velocities are faster in the northern ophiolite regions compared to the southern Oman region, while shear velocities in the middle crust are faster in the Southern Oman region compared to the ophiolite region. This observation coincides well with cretaceous to Eocene marine platform sequences overlying Precambrian to Cambrian basement of the southern part. Joint inversion analysis shows that the Moho depth of Oman varies from 34 km in the southern region to 48 km in the northern part. Abstract Copyright (2011), RAS.

To study He effects in nuclear fusion conditions, He is co-implanted with damage ions to reproduce the correct He/dpa ratios in the desired or available depth range. However, the short-term fate of these He ions, i.e. over the time scales of their own collisional phase, has not been yet unequivocally established. Here we present a computational study of the short-term evolution of He implantation in an Fe substrate at 700 K to approximate the conditions encountered in dual ion-implantation studies in ferritic materials. Using a combination of SRIM, molecular dynamics and kinetic Monte Carlo (kMC), we calculate the fraction of He atoms that end up in substitutional sites shortly after implantation, i.e. before they contribute to long-term microstructural evolution. We find that fractions of at most 3% should be expected for most implantation studies. Additionally, to inform the kMC calculations, we carry out an exhaustive calculation of interstitial He migration energy barriers in the vicinity of matrix vacancies and find that they vary from approximately 20-60 meV depending on the separation and orientation of the He-vacancy pair.

We discuss how the heat of formation in both alloys correlates with the charge transfer between the alloy components, and how the specific behavior of the density of states in the vicinity of the Fermi level promotes the stabilization of the U sub(2)Mo compound. Our calculations suggest that, due to the existence of a single gamma -phase over the typical fuel operation temperatures, gamma -U-Mo alloys should indeed have much lower constituent redistribution than gamma -U-Zr alloys for which binodal decomposition causes a high degree of constituent redistribution.

FT fuels typically contain a high concentration of lightly methylated iso-alkanes, whereas petroleum derived jet and diesel fuels contain large fractions of n-alkanes, cycloalkanes, and aromatics plus some lightly methylated iso-alkanes. In order to better understand the combustion characteristics of FT and petroleum fuels, this study presents new experimental data for 2-methylheptane and n-octane in an opposed-flow diffusion flame. The high temperature oxidation of 2-methylheptane and n-octane has been modeled using an extended transport database and a reaction mechanism consisting of 3401 reactions involving 714 species. The proposed model shows good qualitative and quantitative agreement with the experimental data. The measured and predicted concentrations of 1-alkenes and ethylene are higher in the n-octane flame, while the concentrations of iso-alkenes (especially iso-butene) and propene are higher in the 2-methylheptane flame. The proposed chemical kinetic model is used to delineate the reactions pathways leading to these observed differences in product species concentrations. An uncertainty analysis was conducted to assess experimental and modeling uncertainties. The results indicate that the simulations are sensitive to the transport parameters used to calculate fuel diffusion.

In this scenario, CO (sub 2) -rich and (super 14) C-depleted subsurface Antarctic-sourced water, ventilates the thermocline where it is purged to the atmosphere in the equatorial regions, a view that has been met with conflicting results. Using a novel approach (paired surface and deep-dwelling planktonic foraminifer radiocarbon analyses), we document that the equatorial Atlantic thermocline did not see old, (super 14) C-depleted water, which would be characteristic of the proposed isolated deep ocean CO (sub 2) reservoir. Data from several studies concur that, during the deglaciation, Antarctic intermediate waters were contributing to Atlantic thermocline waters even more than today, therefore, our observations challenge the current purging hypothesis. Together with other studies, these results suggest that the mechanism responsible for the deglacial CO (sub 2) rise cannot invoke contemporary circulation modes and/or thermocline ventilation pathways.

Structural genomics is an overloaded term and requires some definition to bound the discussion; we give a brief description of public and private structural genomics endeavors, along with some of their objectives, their activities, their capabilities, and their limitations. We discuss how structural genomics might impact mutagen research in three different scenarios: at a structural genomics center, at a lab with modest resources that also conducts structural biology research, and at a lab that is conducting mutagen research without in-house experimental structural biology. Applications span functional annotation of single genes or SNP, to constructing gene networks and pathways, to an integrated systems biology approach. Structural genomics centers can take advantage of systems biology models to target high value targets for structure determination and in turn extend systems models to better understand systems biology diseases or phenomenon. Individual investigator run structural biology laboratories can collaborate with structural genomics centers, but can also take advantage of technical advances and tools developed by structural genomics centers and can employ a structural genomics approach to advancing biological understanding. Individual investigator-run non-structural biology laboratories can also collaborate with structural genomics centers, possibly influencing targeting decisions, but can also use structure based annotation tools enabled by the growing coverage of protein fold space provided by structural genomics. Better functional annotation can inform pathway and systems biology models.

Human lymphoblastoid (HL) cells from two unrelated individuals were exposed to graded doses of radiation spanning the range of 1-10cGy were analyzed by transcriptome profiling, qPCR and bioinformatics, in comparison to sham irradiated samples. A set of a arrow right 480 genes showed consistent responses in both cell lines; these genes were associated with homeostasis mechanisms (e.g., membrane signaling, molecule transport), subcellular locations (e.g., Golgi, and endoplasmic reticulum), and involved diverse signal transduction pathways. The majority of radiation-modulated genes had plateau-like responses across 1-10cGy, some with suggestive evidence that transcription was modulated at doses below 1cGy. MYC, FOS and TP53 were the major network nodes of the low-dose-response in HL cells. Comparison our low dose expression findings in HL cells with those of prior studies in mouse brain after whole body exposure, in human keratinocyte cultures, and in endothelial cells cultures, indicates that certain components of the low dose radiation response are broadly conserved across cell types and tissues, independent of proliferation status.

AN - 869582921; 21324614 AB - This paper describes hydrogen ((2)H/(1)H), nitrogen ((15)N/(14)N), and oxygen ((18)O/(16)O) isotopic characterization of ammonium metavanadate (NH(4)VO(3)), a toxic industrial chemical (TIC). We analyzed nineteen high purity compounds obtained from nine suppliers, which show large ranges in trivariate stable isotope compositions, nearly 100-fold greater than analytical uncertainty. Covariation between δ(2)H and δ(15)N values indicates these ratios can be used to trace ammonia compounds, which are critical for the industrial purification of vanadyl ions and precipitation of ammonium metavanadate crystals. δ(2)H and δ(18)O plot far from the Meteoric Water Line (MWL), and suggest materials and industrial processing may lead to decoupling of H and O isotopes. We show how stable isotope characterization is a valuable forensic tool that discriminates between NH(4)VO(3) samples due to differences in source materials, modes of production, and facility location.

Here, we describe a bacterium, strain GFAJ-1 of the Halomonadaceae, isolated from Mono Lake, California, that is able to substitute arsenic for phosphorus to sustain its growth. Our data show evidence for arsenate in macromolecules that normally contain phosphate, most notably nucleic acids and proteins. Exchange of one of the major bio-elements may have profound evolutionary and geochemical importance.

Although there is much evidence that favors a very hot and deep magma ocean for the major core formation event on Earth, many smaller planetesimals likely never became hot enough to generate the wide-scale melting required for such a scenario. Furthermore, there is evidence that planetesimal cores formed rapidly (within 3 My). An inefficient percolative flow mechanism has been suggested to be viable for systems that have a metallic melt fraction in excess of the percolation threshold (approximately 5 vol%), provided that the permeability of these connected melts is high enough to remove the majority of the core liquid from the silicate matrix in such a relatively short time span. More accurate knowledge of the permeability of core forming melts requires a detailed understanding of how the melt is connected in three dimensions, and the complex relationships between melt volume, connectedness and permeability. In this study, we calculated the permeability of core forming metallic liquids (Fe (sub 67) S (sub 33) ) within a silicate matrix by lattice-Boltzmann simulations of flow through digital volumes generated from three-dimensional, synchrotron-based X-ray tomographic images of experimental run samples synthesized at 1300 degrees C and 1 GPa. Electrical conductivity measurements were also conducted on the same pre-synthesized samples to independently determine the percolation (connectivity) threshold. The percolation threshold of these samples was determined to be higher than some earlier measurements (>6 vol%), and the calculated permeability is substantially lower than previously estimated. As a consequence, although percolation still appears viable for some planetesimal sized objects, it may be a secondary mechanism, acting in conjunction with flow induced through other processes such as deformation or more wide spread melting.

Meteoric (super 10) Be depth profiles were determined using measurements from 30 hillslope soil and bedrock core samples in an effort to constrain (super 10) Be inventories. The SSHO is located in the temperate climate zone of central Pennsylvania and comprises a first-order watershed developed entirely on a Fe-rich, organic-poor, Silurian-aged shale. Two major perturbations to the landscape have occurred at SSHO in the geologically recent past, including significant and sustained periglacial activity until after the retreat of the Laurentide ice sheet ( approximately 21 ka) and deforestation during early colonial land-use. Bulk soil samples (n=16) were collected at three locations along a planar hillslope on the southern ridge of the catchment, representing the ridge top, mid-slope and valley floor. Rock chip samples (n=14) were also collected from a 24m deep core drilled into the northern ridge top. All meteoric (super 10) Be concentration profiles show a declining trend with depth, with most of the (super 10) Be retained in the uppermost decimeters of the soil. Meteoric (super 10) Be inventories are higher at the mid-slope and valley floor sample sites, at 3.71+ or -0.02X10 (super 10) at/cm (super 2) and 3.69+ or -0.02X10 (super 10) at/cm (super 2) , than at the ridge top site (1.90+ or -0.01X10 (super 10) at/cm (super 2) ). The (super 10) Be inventory at the convex ridge top site implies a minimum residence time of approximately 10.6 ka, or if erosion is steady, an erosion rate of 19.4+ or -0.2 m/My.

Although isotope separation by diffusion is expected on theoretical grounds, the dependence on mass is highly variable for different elements and in different media. Silicate liquid diffusion experiments using simple liquid compositions were carried out to further probe the compositional dependence of diffusive isotopic discrimination and its relationship to liquid structure. Two diffusion couples consisting of the mineral constituents anorthite (CaAl (sub 2) Si (sub 2) O (sub 8) ; denoted AN), albite (NaAlSi (sub 3) O (sub 8) ; denoted AB), and diopside (CaMgSi (sub 2) O (sub 6) ; denoted DI) were held at 1450 degrees C for 2 h and then quenched to ambient pressure and temperature. Major-element as well as Ca and Mg isotope profiles were measured on the recovered quenched glasses. In both experiments, Ca diffuses rapidly with respect to Si. In the AB-AN experiment, D (sub Ca) /D (sub Si) nearly equal 20 and the efficiency of isotope separation for Ca is much greater than in natural liquid experiments where D (sub Ca) /D (sub Si) nearly equal 1. In the AB-DI experiment, D (sub Ca) /D (sub Si) nearly equal 6 and the efficiency of isotope separation is between that of the natural liquid experiments and the AB-AN experiment. In the AB-DI experiment, D (sub Mg) /D (sub Si) nearly equal 1 and the efficiency of isotope separation for Mg is smaller than it is for Ca yet similar to that observed for Mg in natural liquids. The results from the experiments reported here, in combination with results from natural volcanic liquids, show clearly that the efficiency of diffusive separation of Ca isotopes is systematically related to the solvent-normalized diffusivity - the ratio of the diffusivity of the cation (D (sub Ca) ) to the diffusivity of silicon (D (sub Si) ). The results on Ca isotopes are consistent with available data on Fe, Li, and Mg isotopes in silicate liquids, when considered in terms of the parameter D (sub cation) /D (sub Si) . Cations diffusing in aqueous solutions display a similar relationship between isotopic separation efficiency and D (sub cation) /D (sub H2O) , although the efficiencies are smaller than in silicate liquids. Our empirical relationship provides a tool for predicting the magnitude of diffusive isotopic effects in many geologic environments and a basis for a more comprehensive theory of isotope separation in liquid solutions. We present a conceptual model for the relationship between diffusivity and liquid structure that is consistent with available data.

In the last few years, experiments and modeling have been performed on higher molecular weight components of relevance to diesel fuel such as n-hexadecane (n-cetane) and 2,2,4,4,6,8,8-heptamethylnonane (iso-cetane). Chemical kinetic models have been developed for all the n-alkanes up to 16 carbon atoms. Also, there has been experimental and modeling work on lower molecular weight surrogate components such as n-decane and n-dodecane that are most relevant to jet fuel surrogates, but are also relevant to diesel surrogates where simulation of the full boiling point range is desired. For two-ring compounds, experimental work on decalin and tetralin recently has been published. For esters, kinetic mechanisms for compounds of lower molecular weights but similar to those found in typical biodiesel blendstocks also have been published. For multi-component surrogate fuel mixtures, recent work on modeling of these mixtures and comparisons to real diesel fuel is reviewed. Detailed chemical kinetic models for surrogate fuels are very large in size, so it is noteworthy that significant progress also has been made in improving the mechanism reduction tools that are needed to make these large models practicable in multi-dimensional reacting flow simulations of diesel combustion. Nevertheless, major research gaps remain. In the case of iso-alkanes, there are experiments and modeling work on only one of relevance to diesel: iso-cetane. Also, the iso-alkanes in diesel are lightly branched and no detailed chemical kinetic models or experimental investigations are available for such compounds. More components are needed to fill out the iso-alkane boiling point range. For the aromatic class of compounds, there has been little work for compounds in the boiling point range of diesel. Most of the new work has been on alkyl aromatics that are of the range C7-C9, below the C10-C20 range that is needed. For the chemical classes of cycloalkanes and esters, experiments and modeling on higher molecular weight components are warranted. Finally for multi-component surrogates needed to treat real diesel, the inclusion of higher molecular weight components is needed in models and experimental investigations.

For crystals grown from aqueous solution, there is no general theory that relates reaction rate to mass, but the contribution of isotope-specific reaction rates to the net isotope composition of a mineral must be related to processes occurring at the mineral-fluid interface. Laboratory experiments have shown that the Ca isotope composition (delta (super 44) Ca) of calcite precipitated from aqueous solution varies considerably (up to 1.5ppm) and correlates with the crystal growth rate (R). Generally, inorganic calcite precipitation experiments yield calcite crystals that are enriched in the light isotope of Ca relative to the parent solution. The degree of light isotope enrichment correlates with Sr/Ca in calcite. These observations indicate that variations in delta (super 44) Ca in calcite reflect a mass dependence on reaction rate coefficients (k) and that the physical process responsible for mass discrimination is also responsible for trace element discrimination. We postulate that dehydration/rehydration kinetics of Ca (super 2+) and Sr (super 2+) and/or the presence of impurities on the mineral surface are controlling the kinetic isotope and trace element effects. If true, the presence of other ions (e.g. NH (sub 4) (super +) ) in solution should perturb the stability of the hydration shell of Ca (super 2+) and Sr (super 2+) and also interfere with their incorporation into the mineral lattice. We present results from inorganic calcite precipitation experiments using two solutions that differ in ionic strength (I=0.095 vs. I=0.485 mol/l). In low ionic strength experiments, we observe correlations between delta (super 44) Ca, Sr/Ca and R that are in excellent agreement with results from a previous study that used a similar parent solution composition (Tang et al., GCA, 2008). In our initial experiments at high ionic strength, values of delta (super 44) Ca vs. R and Sr/Ca vs. R lie off the previous trends, but delta (super 44) Ca and Sr/Ca co-vary such that delta (super 44) Ca vs. Sr/Ca is relatively independent of solution composition. Additional experiments are underway and results will be discussed in the context of molecular-scale processes - and their liquid composition-dependence - controlling isotopic and trace element incorporation into minerals.

Exposure of silicate and especially carbonate minerals to elevated CO (sub 2) (e.g. flue gas) can effectively increase the reaction rates leading to CO (sub 2) capture and storage via bicarbonate and/or carbonate formation (1). However, the slow kinetics of the silicate/CO (sub 2) reactions appear to require additional chemical and/or physical treatment, especially in consuming more dilute CO (sub 2) such as found in air. Because of the sensitivity of carbonate and silicate mineral dissolution to acids, and given the ability of saline water electrolysis to generate strong acids, it has been previously shown that electrochemistry can be used to accelerate mineral weathering for purposes of air CO (sub 2) mitigation (2, 3). To explore this further, powdered wollastonite or ultramafic rock standard (UM-4) was encased around the acidic anode of a saline water electrolysis cell composed of graphite electrodes and a 0.25M Na (sub 2) SO (sub 4) electrolyte solution. After 0.5 to 1.5 hrs of electricity application (3.5V (sub dc) , 5-10mA), the electrolyte pH rose to as much as 11.1 (initial and blank pH's <6.6). Subsequent bubbling of these basic solutions with air lowered pH by at least 2 units and increased dissolve carbon content (primarily bicarbonate) by as much as 50X that of the blanks. While Ca (super 2+) and Mg (super 2+) concentrations were elevated, these were insufficient to balance the majority of the bicarbonate anions in solution. We suggest that in these experiments the silicate minerals acted as acid absorbers, forming mostly insoluble CaSO (sub 4) and MgSO (sub 4) at the anode, thus allowing NaOH formation at the cathode to accumulate in solution, in turn reacting with air CO (sub 2) to form NaHCO (sub 3) . Longer electrolysis times and/or alternative electrolyte solutions might allow formation and precipitation of Ca or Mg carbonates. Such electrochemistry might ultimately provide a safe, efficient way to harness the planet's: i) large, off-peak or off-grid renewable electricity potential, ii) abundant basic minerals, and iii) vast natural brine electrolytes for air CO (sub 2) mitigation and carbon-negative H (sub 2) production.

Despite their potential importance in soil nitrogen and carbon cycling, comparatively little is known about their dynamics in soils. Here we present the results of an investigation into the mineral interactions and micro-scale behavior of chitin in ectomycorrhizal mats - a system adapted to rapid cycling of amino sugars. The aim of this study was to follow the micro-scale dynamics of (super 13) C- and (super 15) N-labeled chitin during a 3-week incubation in mycorrhizal mat soil collected from a Oregon andic soil under Douglas-fir forest. Based upon previous findings, we hypothesized that the isotopic label would accumulate in bacterial cells associated with fungal hyphae due to their ability to rapidly process amino sugars. In contrast, nano-scale secondary ion mass-spectrometry (NanoSIMS) imaging of hyphae-associated soil organic matter, minerals, and bacteria revealed a preferential association of (super 15) N with Fe-rich particles at the end of the experiment. Synchrotron-based Scanning Transmission X-ray spectromicroscopy (STXM/NEXAFS) at the C, N and Fe K-edge suggests that these hyphae-associated microstructures consist of thin coatings of amine N on Fe (oxyhydr)oxides. Our results are consistent with recent observations of preferential binding of amine N to Fe-rich minerals and suggest a role of Fe (oxyhydr)oxide surfaces in N cycling of organic layers soils. No enrichment of (super 13) C was found at these locations, possibly due to the lower levels of overall (super 13) C abundance. We further discuss advantages and challenges (e.g. data representation, replication, appropriate controls) of the combined application of isotopic and spectroscopic imaging techniques for the investigation of soil C and N cycling.

We use these data to understand better the efficiency of glacial erosion and to infer the timing, pattern, and rate of ice loss after the last glaciation. In general, the ages of paired bedrock and boulder samples are in close agreement (r (super 2) =0.72). Eleven of the fourteen paired bedrock and boulder samples are indistinguishable at 1sigma ; this concordance indicates that subglacial erosion rates are sufficient to remove most or all (super 10) Be accumulated during previous periods of exposure, and that few, if any, nuclides are inherited from pre-Holocene interglaciations. The new data agree well with previously-published landscape chronologies from this area, and suggest that two chronologically-distinct land surfaces exist: one outside the Fjord Stade moraine complex ( approximately 10.3+ or -0.4 ka; n=7) and another inside ( approximately 8.0+ or -0.7 ka; n=21). Six (super 10) Be ages from directly outside the historic (Little Ice Age) moraine show that the ice margin first reached its present-day position approximately 7.6+ or -0.4 ka. Early Holocene ice margin retreat rates after the deposition of the Fjord Stade moraine complex were approximately 100-110 m yr (super -1) . Sikuijuitsoq Fjord is a tributary to the much larger Jakobshavn Isfjord and the deglaciation chronologies of these two fjords are similar. This synchronicity suggests that the ice stream in Jakobshavn Isfjord set the timing and pace of early Holocene deglaciation of the surrounding ice margin. Abstract Copyright (2011) Elsevier, B.V.

Herein, we present high-resolution, mono-specific (P. wuellerstorfi), benthic foraminiferal delta (super 13) C records from a depth transect of cores to reconstruct ventilation changes in the New Zealand region of the Southern Ocean. The cores span depths of; 600m (RR0503 87TC/87JPC), 1200m (RR0503 79JPC), 1600m (RR0503 83TC/83JPC), 2045m (H214;), 2500m (RR0503 125JPC), and 3800m (RR0503 41JPC). Age control is based on tephrostratigraphy, and additionally constrained by delta (super 18) O. During the last glacial period, the difference in delta (super 13) C values (Delta delta (super 13) C) between 600 and 3800m, is approximately 1.7ppm, significantly higher than during the Holocene ( approximately 0.7ppm), implying reduced glacial ventilation. In the early deglaciation, delta (super 13) C increased at deep sites, suggesting increasing ventilation. Glacial delta (super 13) C values at 1200m lie evenly between the values of the deeper sites (1600 - 3800m) and the shallowest core (600m), suggesting a distinct glacial intermediate water mass. During the ACR, delta (super 13) C at 1200m increased and converged with values at 600m, suggesting that a single water mass to bathed 600 - 1200m. Following the ACR, delta (super 13) C values at 1200m again become distinct from the shallow and deep sites and the delta (super 13) C in the deeper cores increases rapidly (by approximately 0.5ppm), reducing the Delta delta (super 13) C to approximately 1.0ppm post-ACR. These results indicate a step-wise change in stratification and ventilation across the ACR boundary, suggesting the ACR had both a short term and enduring impact on shallow interior ventilation in the Southern Pacific.

It has been proposed that the formation of a gamma ' intermediate phase may be responsible for the unusual double-C curve kinetics reported for this isothermal martensitic transformation. While a gamma ' intermediate phase was not observed at either -120 [deg]C or -155 [deg]C, an unexplained shoulder on the [delta] (1 1 1) peak was detected at -155 [deg]C. The isothermal kinetics of the [delta] --> alpha ' transformation appear to fit a Johnson-Mehl-Avrami-Kolmogorov equation, but the exponent is not described by existing JMAK theory. The double-C curve kinetics of the [delta] to alpha ' transformation remain unresolved in plutonium science, and understanding this behavior is key to predicting phase stability in aging Pu-Ga alloys.

We present a glacial chronology for the valley based on geomorphological mapping and cosmogenic nuclide ( (super 10) Be) exposure ages (n=10) of boulders on moraines and lake shorelines. There are five prominent moraine belts in the Lago San Martin Valley, associated with extensive sandar (glaciofluvial outwash plains) and former lake shorelines. Cosmogenic nuclide exposure ages for boulders on these moraines indicate that they formed at 14.3+ or -1.7 ka, 22.4+ or -2.3 ka, 34.4+ or -3.4 ka to 37.6+ or -3.4 ka (and possibly 60+ or -3.5 ka), and 99+ or -11 ka (1sigma ). These dated glacier advances differ from published chronologies from the Lago San Martin Valley based on (super 14) C age determinations from organic sediments and molluscs in meltwater channels directly in front of moraines or in kettleholes within end moraine ridges. The moraine boulder ages also point to possible pre-LGM glacial advances during the last glacial cycle and a key observation from our data is that the LGM glaciers were probably less extensive in the Lago San Martin Valley than previously thought.

The stability of carbon-hydrogen systems at depths greater than a few thousand meters is poorly understood and the extent of abiogenic HCs in the Earth mantle remains controversial. We report ab initio molecular dynamics simulations and free energy calculations aimed at investigating the formation of higher HCs from dissociation of pure methane, and in the presence of carbon surfaces and transition metals, for pressures of 2 to 30 GPa and temperatures of 800 to 4,000 K. We show that for T . 2,000 K and P . 4 GPa HCs higher than methane are energetically favored. Our results indicate that higher HCs become more stable between 1,000 and 2,000 K and P . 4 GPa. The interaction of methane with a transition metal facilitates the formation of these HCs in a range of temperature where otherwise pure methane would be metastable. Our results provide a unified interpretation of several recent experiments and a detailed microscopic model of methane dissociation and polymerization at high pressure and temperature.

We measured the (super 36) Cl- (super 36) S-isotope abundance in wadalite (<15 mu m), a secondary chlorine-bearing mineral found in calcium-aluminum-rich inclusions (CAIs) in the Allende CV chondrite, to decipher the origin of the SLR (super 36) Cl (tau (sub 1/2) approximately 3 X 10 (super 5) yr) in the early solar system. Its presence, initial abundance, and the noticeable decoupling from (super 26) Al raise serious questions about the origin of SLRs. The inferred initial (super 36) Cl abundance for wadalite, corresponding to a (super 36) Cl/ (super 35) Cl ratio of (1.81 + or - 0.13) X 10 (super -5) , is the highest (super 36) Cl abundance ever reported in any early solar system material. The high level of (super 36) Cl in wadalite and the absence of (super 26) Al ( (super 26) Al/ (super 27) Al < or = 3.9 X 10 (super -6) ) in co-existing grossular (1) unequivocally support the production of (super 36) Cl by late-stage solar energetic particle irradiation in the protoplanetary disk and (2) indicates that the production of (super 36) Cl, recorded by wadalite, is unrelated to the origin of (super 26) Al and other SLRs ( (super 10) Be, (super 53) Mn) recorded by primary minerals of CAIs and chondrules. We infer that (super 36) Cl was largely produced by irradiation of a volatile-rich reservoir in an optically thin protoplanetary disk adjacent to the region in which the CV chondrite parent asteroid accreted while the Sun was a weak T Tauri star. Subsequently, (super 36) Cl accreted into the Allende CV chondrite together with condensed water ices. Copyright (Copyright) 2011. The American Astronomical Society. All rights reserved.

Alternating phases of deposition and erosion lead to the formation of generations of talus flatirons in which ancient ones are located farther from the source cliff. The existing conceptual model of this systematic spatial distribution of talus flatirons is related to glacial-interglacial climatic cycles and to relatively high rates of cliff retreat. Three groups of talus flatirons were analyzed in the northeastern hyperarid Negev desert. The analyses include mapping, age determination using optically stimulated luminescence and cosmogenic nuclide exposure dating, electrical resistivity tomography and sedimentological and soil analyses. All talus flatirons contain gypsic-salic soil catena typical to hyperarid climate (<80 mm yr (super -1) ). No pedogenic indicators of past wetter environments such as buried calcic soil horizons, evidence of intense biogenic activity, or buried organic material were observed. (super 10) Be exposure ages of the talus flatirons suggest that they were deposited during the middle Pleistocene; approximately 610 ka and approximately 170 ka for the oldest and intermediate-aged talus flatiron groups, respectively. These ages, combined with the present location of the talus flatirons relative to the source cliff yield retreat rates of 6-12 and approximately 200 m Ma (super -1) for the bedrock cliff and talus flatiron apex, respectively, and in opposite directions. Our results show that (a) climatic changes at glacial-interglacial time scales are not the main controls over the formation of talus flatiron generation, and (b) that significant cliff retreat is not the main cause for the systematic spatial distribution of talus flatiron generations relative to the cliff. Our results indicate that the process of talus flatiron formation in the Negev desert must be associated with the balance between production, deposition, and removal of clasts under hyperarid conditions with only a minor cliff retreat.

We use the fact that many aftershocks are repetitive, producing similar waveforms. By clustering events based on correlation measures of waveform similarity, the number of independent event instances that must be examined in detail by analysts may be reduced. Our system processes array data and acquires waveform templates with a short-term average (STA)/long-term average (LTA) detector operating on a beam directed at the P phases of the aftershock sequence. The templates are used to create correlation-type (subspace) detectors that sweep the subsequent data stream for occurrences of the same waveform pattern. Events are clustered by association with a particular detector. Hundreds of subspace detectors can run in this framework a hundred times faster than in real time. Nonetheless, to check the growth in the number of detectors, the framework pauses periodically and reclusters detections to reduce the number of event groups. These groups define new subspace detectors that replace the older generation of detectors. Because low-magnitude occurrences of a particular signal template may be missed by the STA/LTA detector, we advocate restarting the framework from the beginning of the sequence periodically to reprocess the entire data stream with the existing detectors. We tested the framework on 10 days of data from the Nevada Seismic Array (NVAR) covering the 2003 San Simeon earthquake. One hundred eighty-four automatically generated detectors produced 676 detections resulting in a potential reduction in analyst workload of up to 73%.

Our assessment is that, assuming that grain boundary diffusion in metallic fuels is similar to that in other metals, it is reasonable to expect that lattice diffusion coefficients can be determined from short time gas release experiments and the product of the grain boundary diffusion coefficient, the segregation factor, and the boundary width can be extracted from gas release experiments at longer times.

These components, methyl stearate, methyl oleate, methyl linoleate, methyl linolenate, and methyl palmitate, are large methyl ester molecules, some with carbon[inline image]carbon double bonds, and kinetic mechanisms for them as a family of fuels have not previously been available. Of particular importance in these mechanisms are models for alkylperoxy radical isomerization reactions in which a C[inline image]C double bond is embedded in the transition state ring. The resulting kinetic model is validated through comparisons between predicted results and a relatively small experimental literature. The model is also used in simulations of biodiesel oxidation in jet-stirred reactor and intermediate shock tube ignition and oxidation conditions to demonstrate the capabilities and limitations of these mechanisms. Differences in combustion properties between the two biodiesel fuels, derived from soy and rapeseed oils, are traced to the differences in the relative amounts of the same five methyl ester components.

The material and its constituents were decomposed using standard thermal analysis techniques (DSC and TGA) and the decomposition kinetics are reported using different kinetic models. Pressed parts and prill were thermally damaged, i.e. heated to temperatures that resulted in material changes but did not result in significant decomposition or explosion, and analyzed. In general, the thermally damaged samples showed a significant increase in porosity and decrease in density and a small amount of weight loss. These PBXN-9 samples appear to sustain more thermal damage than similar HMX-Viton A formulations and the most likely reasons are the decomposition/evaporation of a volatile plasticizer and a polymorphic transition of the HMX from [beta] to [delta] phase.

To provide independent constrains on the effects of temperature, oxygen fugacity and silicate melt composition, isobaric (3 GPa) experiments were conducted in piston cylinder apparatus at temperature between 1600 and 2600 degrees C, relative oxygen fugacities of IW-1.5 to IW-3.5, and for silicate melt compositions ranging from basalt to peridotite. The effect of pressure was investigated through a combination of piston cylinder and multi-anvil isothermal experiments between 0.5 and 18 GPa at 1900 degrees C. Oxidation states of siderophile elements in the silicate melt as well as effect of carbon saturation on partitioning are also derived from these results. For some elements (e.g. Ga, Ge, W, V, Zn) the observed temperature dependence does not define trends parallel to those modeled using metal-metal oxide free energy data. We correct partitioning data for solute interactions in the metallic liquid and provide a parameterization utilized in extrapolating these results to the P-T-X conditions proposed by various core formation models. A single-stage core formation model reproduces the mantle abundances of several siderophile elements (Ni, Co, Cr, Mn, Mo, W, Zn) for core-mantle equilibration at pressures from 32 to 42 GPa along the solidus of a deep peridotitic magma ocean ( approximately 3000 K for this pressure range) and oxygen fugacities relevant to the FeO content of the present-day mantle. However, these P-T-fO (sub 2) conditions cannot produce the observed concentrations of Ga, Ge, V, Nb, As and P. For more reducing conditions, the P-T solution domain for single stage core formation occurs at subsolidus conditions and still cannot account for the abundances of Ge, Nb and P. Continuous core formation at the base of a magma ocean at P-T conditions constrained by the peridotite liquidus and fixed fO (sub 2) yields concentrations matching observed values for Ni, Co, Cr, Zn, Mn and W but underestimates the core/mantle partitioning observed for other elements, notably V, which can be reconciled if accretion began under reducing conditions with progressive oxidation to fO (sub 2) conditions consistent with the current concentration of FeO in the mantle as proposed by Wade and Wood (2005). However, neither oxygen fugacity path is capable of accounting for the depletions of Ga and Ge in the Earth's mantle. To better understand core formation, we need further tests integrating the currently poorly-known effects of light elements and more complex conditions of accretion and differentiation such as giant impacts and incomplete equilibration.

We designed and tested an integrated nucleic acid extraction and amplification device employing a loop-mediated isothermal amplification (LAMP) or reverse transcriptase-LAMP assay. Our system provides a screening tool with polymerase-chain-reaction-level sensitivity and specificity for outbreak detection, response, and recovery. Time to result is similar to 90 min. The device utilizes a swab that collects sample and then transfers it to a disc of cellulose-based nucleic acid binding paper. The disc is positioned within a disposable containment tube with a manual loading port. In order to test for the presence of target pathogens, LAMP reagents are loaded through the tube's port into contact with the sample containing cellulose disc. The reagents then are isothermally heated to 63 degree C for similar to 1 h to achieve sequence-specific target nucleic acid amplification. Due to the presence of a colorimetric dye, amplification induces visible color change in the reagents from purple to blue. As initial demonstrations, we detected methicillin resistant Staphylococcus aureus genomic DNA, as well as recombinant and live foot-and-mouth disease virus.

In naturally aged Pu specimens, those He atoms form into bubbles, He-filled vacancy clusters, with a characteristic size distribution centered near 1.4 nm. Upon annealing, the He bubbles are subject to temperature induced changes in the thermodynamic parameters governing their size, which results in a coarsening of the bubble distribution yielding a lower bubble density but larger average bubble sizes. Herein, we investigate, by means of transmission electron microscopy, the coarsening of He bubbles with several annealing treatments. Micrographs subsequent to the annealing treatments as well as in situ observations implicate migration and coalescence as the mechanism for He bubble coarsening with annealing.

Perched vadose zone water at Rainier Mesa has high levels of DOM as a result of microbial degradation of mining debris (diesel, wood, etc.). The Am and Pu sorption K (sub d) s were up to two orders of magnitude lower in water with high DOM (15-19 mg C/L) compared to the same water with DOM removed (<0.4 mg C/L) or in naturally low DOM (0.2 mg C/L) groundwater. In contrast, K (sub d) s of Np and U were less affected by DOM at these solution conditions. Uranium sorption decreased as a result of high dissolved inorganic C (DIC) resulting from microbial degradation of DOM. Thermodynamic model predictions, based on actinide-humic acid stability constants available in the literature, are in general agreement with measured K (sub d) data, correctly predicting the effects of DIC and DOM on actinide retardation. This agreement is encouraging to future modeling efforts and suggests that effects of DOM and DIC can be incorporated into reactive transport modeling predictions. The Am and Pu transport rates in Rainier Mesa tunnel waters will be substantially faster as a result of the elevated DOM levels. Low diffusion rates of actinide-DOM macromolecular complexes may focus Pu and Am transport into fractures and minimize retardation via matrix diffusion. The resulting transport behavior will affect actinide distribution patterns and associated risk estimates.

We have performed detailed simulations of the hydromechanical response in the vicinity of the KB-502 CO sub(2 injection well specifically because the morphology of the observed surface deformation differed from that above the other injectors at the field. We have simulated the mm-scale uplift of the overburden associated with the injection and compared the results with observed ground surface deformation measured by InSAR. By solely including conducting and bounding faults in the model we achieve better agreement with the magnitude of the observed net uplift at the ground surface, but not the shape of the uplift pattern. However, by further including flow into a hypothetical vertical extension of a fault, our simulations better match the morphology of the surface deformation. Our results indicate that the best fit is obtained through a combination of reservoir and fault pressurization, rather than either alone. However, our analysis required assumptions regarding the mechanical properties of the faults and the overburden. These results demonstrate that InSAR provides a powerful tool for gaining insight into the fate of fluid in the subsurface, but also highlight the need for detailed, accurate static geomodels.)

We present cosmogenic radionuclide (super 10) Be inventories at 17 sites in southern and western Tibet (32 crests, 249 samples) and infer the range of permissible emplacement ages based on these analyses. Individual large embedded rock and boulder samples were collected from the crests of moraine surfaces and analyzed for (super 10) Be abundance. We consider two scenarios to interpret the age of glacial recession leading to the moraine surface formation from these sample exposure ages: 1) Erosion of the moraine surface is insignificant and so the emplacement age of the moraines is reflected by the mean sample age; and 2) Erosion progressively exposes large boulders with little prior exposure, and so the oldest sample age records the minimum moraine emplacement age. We found that depending on the scenario chosen, the moraine emplacement age can vary by > 50% for approximately 100 ka-old samples. We consider two scaling models for estimating the production rates of (super 10) Be in Tibet, which has an important, although lesser, effect on inferred moraine ages. While the data presented herein effectively increase the database of sample exposure ages from Tibet by approximately 20%, we find that uncertainties related to the interpretation of the (super 10) Be abundance within individual samples in terms of moraine emplacement ages are sufficient to accommodate either a view in which glacial advances are associated with temperature minima or precipitation maxima that are recorded by independent paleoclimate proxies. A reanalysis of published data from moraines throughout Tibet shows that the variation we observe is not unique to our dataset but rather is a robust feature of the Tibetan moraine age database. Thus, when viewed in a similar way with other samples collected from this area, uncertainties within moraine exposure ages obscure attribution of Tibetan glacial advances to temperature minima or precipitation maxima. Our work suggests that more reliable chronologies of Tibetan glaciations will come from improvements in production rate models for this portion of the world, as well as a better understanding of the processes that form and modify these geomorphic surfaces.

This work examines near-surface-pressure tides in climate models that contributed to the Fourth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC); it compares them with tides both from observations and from the Whole Atmosphere Community Climate Model (WACCM), which extends from the earth's surface to the thermosphere. Surprising consistency is found among observations and all model simulations, despite variation of the altitudes of model upper boundaries from 32 to 76 km in the IPCC models and at 135 km for WACCM. These results are consistent with previous suggestions that placing a model's upper boundary at low altitude leads to partly compensating errors-such as reducing the forcing of the tides by ozone heating, but also introducing spurious waves at the upper boundary, which propagate to the surface.

15126963 AB - Crystal and interfacial structures of oxide nanoparticles and radiation damage in 16Cr-4.5Al-0.3Ti-2W-0.37 Y sub(2)O sub(3) ODS ferritic steel have been examined using high-resolution transmission electron microscopy (HRTEM) techniques. Oxide nanoparticles with a complex-oxide core and an amorphous shell were frequently observed. The crystal structure of complex-oxide core is identified to be mainly monoclinic Y sub(4)Al sub(2)O sub(9) (YAM) oxide compound. Orientation relationships between the oxide and the matrix are found to be dependent on the particle size. Large particles (20 nm) tend to be incoherent and have a spherical shape, whereas small particles (10 nm) tend to be coherent or semi-coherent and have a faceted interface. The observations of partially amorphous nanoparticles and multiple crystalline domains formed within a nanoparticle lead us to propose a three-stage mechanism to rationalize the formation of oxide nanoparticles containing core/shell structures in as-fabricated ODS steels. Effects of nanoparticle size and density on cavity formation induced by (Fe[super]8+ + He[super]+) dual-beam irradiation are briefly addressed.

Here we describe a Holocene paleoclimate record from sediment cores obtained from Lago Fagnano, a large lake in southern Tierra del Fuego at 55 degrees S, to investigate past changes in climate related to these two important features of the global climate system. We use an AMS radiocarbon chronology for the last 8000 yr based on pollen concentrates, thereby avoiding contamination from bedrock-derived lignite. Our chronology is consistent with a tephrochronologic age date for deposits from the middle Holocene Volcan Hudson eruption. Combining bulk organic isotopic (delta (super 13) C and delta (super 15) N) and elemental (C and N) parameters with physical sediment properties allows us to better understand sediment provenance and transport mechanisms and to interpret Holocene climate and tectonic change during the last 8000 yr. Co-variability and long-term trends in C/N ratio, carbon accumulation rate, and magnetic susceptibility reflect an overall Holocene increase in the delivery of terrestrial organic and lithogenic material to the deep eastern basin. We attribute this variability to westerly wind-derived precipitation. Increased wind strength and precipitation in the late Holocene drives the Nothofagus forest eastward and enhances run-off and terrigenous inputs to the lake. Superimposed on the long-term trend are a series of abrupt 9 negative departures in C/N ratio, which constrain the presence of seismically-driven mass flow events in the record. We identify an increase in bulk delta (super 13) C between 7000 and 5000 cal yr BP that we attribute to enhanced aquatic productivity driven by warmer summer temperatures. The Lago Fagnano delta (super 13) C record shows similarities with Holocene records of sea surface temperature from the mid-latitude Chilean continental shelf and Antarctic air temperatures from the Taylor Dome ice core record in East Antarctica. Mid-Holocene warming occurred simultaneously across the Antarctic Frontal Zone, and in particular, in locations currently influenced by the Antarctic Circumpolar Current.

New olivine compositional data from phase 2 of the Hawaii Scientific Drilling Project (HSDP2) show that higher Ni-in-olivine at the Hawaiian Islands is due to higher temperatures (T) of melt generation and processing (by c. 300 degrees C) related to the Hawaiian mantle plume. D (sub Ni) is low at high T, so parental Hawaiian basalts are enriched in NiO. When Hawaiian (picritic) parental magmas are transported to shallow depths, olivine precipitation occurs at lower temperatures, where D (sub Ni) is high, leading to high Ni-in-olivine. Similarly, variations in Mn and Fe/Mn ratios in olivines are explained by contrasts in the temperatures of magma processing. Using the most mafic rocks to delimit Siqueiros and Hawaiian Co and Ni contents in parental magmas and mantle source compositions also shows that both suites can be derived from natural peridotites, but are inconsistent with partial melting of natural pyroxenites. Whole-rock compositions at Hawaii and Siqueiros are also matched by partial melting experiments conducted on peridotite bulk compositions. Hawaiian whole-rocks have elevated FeO contents compared with Siqueiros, which can be explained if Hawaiian parental magmas are generated from peridotite at 4-5 GPa, in contrast to pressures of slightly greater than 1 GPa for melt generation at Siqueiros; these pressures are consistent with olivine thermometry, as described in an earlier paper. SiO (sub 2) -enriched Koolau compositions are reproduced if high-Fe Hawaiian parental magmas re-equilibrate at 1-1.5 GPa. Peridotite partial melts from experimental studies also reproduce the CaO and Al (sub 2) O (sub 3) contents of Hawaiian (and Siqueiros) whole-rocks. Hawaiian magmas have TiO (sub 2) contents, however, that are enriched compared with melts from natural peridotites and magmas derived from the Siqueiros depleted mantle, and consequently may require an enriched source. TiO (sub 2) is not the only element that is enriched relative to melts of natural peridotites. Moderately incompatible elements, such as Ti, Zr, Hf, Y, and Eu, and compatible elements, such as Yb and Lu, are all enriched at the Hawaiian Islands. Such enrichments can be explained by adding 5-10% mid-ocean ridge basalt (crust) to depleted mantle; when the major element composition of such a mixture is recast into mineral components, the result is a fertile peridotite mineralogy.

Unfortunately, such near-field observations at distances less than 100 m of fault rupture are few and incomplete. In this study a 3D finite-difference method is used to simulate strong ground motions for a hypothetical M (sub w) 6.5 earthquake at sites within a few tens of meters of the fault to document the nature of strong ground motion at pairs of sites across the fault as a first step toward providing ground-motion input for engineering design applications. We employ several distributed slip kinematic models to examine ground-motion variability. We also examine the ground motions for fault scenarios ranging from vertical strike-slip to low-angle thrust faulting. The results show that the motions have two primary components: (1) far-field waves that undergo focusing and amplification due to finite-source rupture directivity and (2) near-field waves that are sensitive to the tectonic rebound, or fling, of the closest section of the fault to the recording stations. Both the far-field and near-field controlled motions result in nonstationary pulse-like velocity waveforms that have many implications for the design of engineered structures located close to or spanning faults.

Two-dimensional attenuation (q or 1/Q) is derived from the path term, which is calculated via an iterative least-squares inversion that also solves for perturbations to the site and source terms. Source terms agree well with initial CISN M (sub L) s, and site terms agree well with a prior regression analysis; q ranges from low attenuation at 0.001 (Q=1000) to high attenuation at 0.015 (Q=66), with an average of 0.07 (Q=143). The average q is consistent with an amplitude decay function (logA (sub 0) ) for California when q is combined with a simple geometrical spreading rate. Attenuation in California is consistent with the tectonic structure of California, with low attenuation in the Sierra batholith and high attenuation at The Geysers, at Long Valley, and in the Salton trough possibly due to geothermal effects. Also, path terms are an order of magnitude smaller than site and source terms, suggesting that they are not as important in correcting for M (sub L) .

This significant short-term variability highlights the need for geologic records of preinstrumental GIS margin fluctuations in order to better predict future GIS response to climate change. Using (super 10) Be surface exposure ages and radiocarbon-dated lake sediments, we constructed a detailed chronology of ice-margin fluctuations over the past 10 k.y. for Jakobshavn Isbrae, Greenland's largest outlet glacier. In addition, we present new estimates of corresponding local temperature changes using a continuous record of insect (Chironomidae) remains preserved in lake sediments. We find that following an early Holocene advance just prior to 8 ka, Jakobshavn Isbrae retreated rapidly at a rate of approximately 100 m yr (super -1) , likely in response to increasing regional and local temperatures. Ice remained behind its present margin for approximately 7 k.y. during a warm period in the middle Holocene with sustained temperatures approximately 2 degrees C warmer than today, then the land-based margin advanced at least 2-4 km between A.D. 1500-1640 and A.D. 1850. The ice margin near Jakobshavn thus underwent large and rapid adjustments in response to relatively modest centennial-scale Holocene temperature changes, which may foreshadow GIS response to future warming.

Two samples were examined: a load-bearing framework-type texture, where the alloy phase (Fe-Ni-S) was present as isolated spherical inclusions, and an interconnected network-type texture, where the alloy phase was concentrated along the silicate grain boundaries and tended to form an interconnected network. The samples, both containing approximately 10 vol% alloy inclusions, were compressed to 6 GPa, followed by shear deformation at temperatures up to 800 K. Shear strains were introduced by twisting the samples at high pressure and high temperature. At each imposed shear strain, samples were cooled to ambient temperature and tomographic images collected. The three-dimensional tomographic images were analyzed for textural evolution. We found that in both samples, Fe-Ni-S, which is the weaker phase in the composite, underwent significant deformation. The resulting lens-shaped alloy phase is subparallel to the shear plane and has a laminated, highly anisotropic interconnected weak layer texture. Scanning electron microscopy showed that many alloy inclusions became film-like, with thicknesses <1 mu m, suggesting that Fe-Ni-S was highly mobile under nonhydrostatic stress, migrated into silicate grain boundaries, and propagated in a manner similar to melt inclusions in a deforming solid matrix. The grain size of the silicate matrix was significantly reduced under large strain deformation. The strong shape-preferred orientation thus developed can profoundly influence a composite's bulk elastic and rheological properties. High-pressure-high temperature tomography not only provides quantitative observations on textural evolution, but also can be compared with simulation results to derive more rigorous models of the mechanical properties of composite materials relevant to Earth's deep mantle.

Based on concentrations of the cosmogenic radionuclides (super 10) Be, (super 26) Al, (super 36) Cl, and (super 41) Ca in the metal and stone fraction of 16 QUE L5 or LL5 chondrites, we conclude that 13 meteorites belong to a single meteorite shower, QUE 90201, with a large preatmospheric size and a terrestrial age of 125 kyr. Members of this shower have properties typical of L (e.g., pyroxene composition) and LL chondrites (e.g., metal abundance and composition), as well as properties intermediate between the L and LL groups (e.g., olivine composition), and is thus best described as an L/LL5 chondrite. Based on comparison with model calculations, the measured radionuclide concentrations in the metal and stone fractions of QUE 90201 indicate irradiation in an object with a preatmospheric radius of approximately 150 cm, representing one of the largest chondrites known so far. Based on the abundance of small L5 and LL5 chondrites at QUE and their distinct mass distribution, we conclude that the QUE 90201 shower includes up to 2000 fragments with a total recovered mass of 60-70 kg, <% of the preatmospheric mass of approximately 50,000 kg. The mass distribution of the QUE 90201 shower suggests that the meteoroid experienced catastrophic atmospheric fragmentation(s), either because it was a fragile object or it had a high entry velocity.

Experiments were conducted to demonstrate that nucleation of hydriding is promoted by formation of Pu sub(2)O sub(3) sites in the oxide layer. The nucleation mechanism based on diffusion of hydrogen through the PuO sub(2) layer was evaluated and an alternative mechanism based on formation of catalytic Pu sub(2)O sub(3) sites via the Pu-PuO sub(2) reaction is proposed. The possibility of active participation of other impurities and inclusions in the dioxide is also discussed.

In contrast to this, the inversion employed here fits the data in a probabilistic sense and thus provides a quantitative measure of model uncertainty. Our probabilistic model is based on two sources of information: (1) prior information, which is independent from the data, and (2) different geophysical data sets, including thickness constraints, velocity profiles, gravity data, surface wave group velocities, and regional body wave traveltimes. We use a Markov chain Monte Carlo (MCMC) algorithm to sample models from the prior distribution, the set of plausible models, and test them against the data to generate the posterior distribution, the ensemble of models that fit the data with assigned uncertainties. While being computationally more expensive, such a probabilistic inversion provides a more complete picture of solution space and allows us to combine various data sets. The complex geology of the European Arctic, encompassing oceanic crust, continental shelf regions, rift basins and old cratonic crust, as well as the nonuniform coverage of the region by data with varying degrees of uncertainty, makes it a challenging setting for any imaging technique and, therefore, an ideal environment for demonstrating the practical advantages of a probabilistic approach. Maps of depth to basement and depth to Moho derived from the posterior distribution are in good agreement with previously published maps and interpretations of the regional tectonic setting. The predicted uncertainties, which are as important as the absolute values, correlate well with the variations in data coverage and quality in the region. A practical advantage of our probabilistic model is that it can provide estimates for the uncertainties of observables due to model uncertainties. We will demonstrate how this can be used for the formulation of earthquake location algorithms that take model uncertainties into account when estimating location uncertainties.

Despite the complexity of the region, little is known about the detailed lithospheric structure. Using data from 31 new, permanent broadband seismic stations along with results from a previous 29 temporary seismic stations and 3 existing global seismic stations in the region, a 3-D velocity model is developed using joint inversion of teleseismic receiver functions and surface waves. Both group and phase dispersion curves (Love and Rayleigh) were derived from regional and teleseismic events. Additional Rayleigh wave group dispersion curves were determined using ambient noise correlation. Receiver functions were calculated using P arrivals from 789 teleseismic (30 degrees -90 degrees ) earthquakes. The stacked receiver functions and surface wave dispersion curves were jointly inverted to yield the absolute shear wave velocity to a depth of 100 km at each station. The depths of major discontinuities (sediment-basement, crust-mantle, and lithosphere-asthenosphere) were inferred from the velocity-depth profiles at the location of each station. Distinct spatial variations in crustal and upper mantle shear velocities were observed. The Kura basin showed slow ( approximately 2.7-2.9 km/s) upper crustal (0-11 km) velocities but elevated ( approximately 3.8-3.9 km/s) velocities in the lower crust. The Anatolian plateau varied from approximately 3.1-3.2 in the upper crust to approximately 3.5-3.7 in the lower crust, while velocities in the Arabian plate (south of the Bitlis suture) were slightly faster (upper crust between 3.3 and 3.4 km/s and lower crust between 3.8 and 3.9 km/s). The depth of the Moho, which was estimated from the shear velocity profiles, was 35 km in the Arabian plate and increased northward to 54 km at the southern edge of the Greater Caucasus. Moho depths in the Kura and at the edge of the Caspian showed more spatial variability but ranged between 35 and 45 km. Upper mantle velocities were slow under the Anatolian plateau but increased to the south under the Arabian plate and to the east (4.3-4.4 km/s) under the Kura basin and Greater Caucasus. The areas of slow mantle coincided with the locations of Holocene volcanoes. Differences between Rayleigh and Love dispersions at long wavelengths reveal a pronounced variation in anisotropy between the Anatolian plateau and the Kura basin.

This study focuses on a suite of 10 bamboo corals collected from the Pacific and Atlantic basins (250-2136 m water depth) to investigate coral longevity, growth rates, and isotopic signatures. Calcite samples for stable isotopes and radiocarbon were collected from the base the corals, where the entire history of growth is recorded. In three of the coral specimens, samples were also taken from an upper branch for comparison. Radiocarbon and growth band width analyses indicate that the skeletal calcite precipitates from ambient dissolved inorganic carbon and that the corals live for 150-300 years, with extension rates of 9-128 mu m/yr. A linear relationship between coral calcite delta (super 18) O and delta (super 13) C indicates that the isotopic composition is influenced by vital effects (delta (super 18) O:delta (super 13) C slope of 0.17-0.47). As with scleractinian deep-sea corals, the intercept from a linear regression of delta (super 18) O versus delta (super 13) C is a function of temperature, such that a reliable paleotemperature proxy can be obtained, using the "lines method." Although the coral calcite delta (super 18) O:delta (super 13) C slope is maintained throughout the coral base ontogeny, the branches and central cores of the bases exhibit delta (super 18) O:delta (super 13) C values that are shifted far from equilibrium. We find that a reliable intercept value can be derived from the delta (super 18) O:delta (super 13) C regression of multiple samples distributed throughout one specimen or from multiple samples within individual growth bands.

Fully three-dimensional ray tracing is employed to achieve accurate travel time predictions of P and P (sub n) arrivals, requiring the characterization of irregular and discontinuous boundaries. Therefore, we explicitly represent undulating seismic discontinuities in the crust and upper mantle within a spherical tessellation modeling framework. The tessellation-based model architecture is hierarchical in that fine node sampling is achieved by recursively subdividing a base level tessellation. Determining the required node spacing to effectively model a given set of data is problematic, given the uneven sampling of seismic data and the differing wavelengths of actual seismic heterogeneity. To address this problem, we have developed an inversion process called Progressive Multilevel Tessellation Inversion (PMTI) that exploits the hierarchical nature of the tessellation-based design and allows the data to determine the level of model complexity. PMTI serves as an alternative to existing multiresolution approaches and robustly images regional trends while allowing localized details to emerge where resolution is sufficient. To demonstrate our complete modeling concept, we construct a velocity model based on teleseismic P travel time data for global events and regional P (sub n) travel time data for events occurring throughout the Middle East. Input data are a product of the statistical procedure called Bayesloc that simultaneously models all components of a multievent system including event locations, origin times, and arrival times (described in the Myers et al. (2011) companion paper). The initial tomographic image provides a new glimpse of the complex upper mantle velocity anomalies associated with the convergence of the Arabian and Indian plates with Eurasia. More important for event monitoring, the model accurately predicts both teleseismic and regional travel times for events occurring within the Middle East region.

Bayesloc is a formulation of the joint probability distribution spanning multiple-event location parameters, including hypocenters, travel time corrections, pick precision, and phase labels. Stochastic priors may be used to constrain any of the Bayesloc parameters. Markov Chain Monte Carlo sampling is used to draw samples from the joint probability distribution, and the posteriori samples are summarized to infer conventional location parameters such as the hypocenter. The first application of the broad area Bayesloc algorithm is to a data set consisting of all well-recorded events in the Middle East and the most well-recorded events with 5 degrees spatial sampling globally. This sampling strategy is designed to provide the ray coverage needed to determine lithospheric-scale P wave velocity structure in the Middle East using the complementary ray geometry provided by regional (subhorizontal) and teleseismic (subvertical) raypaths and to determine a consistent, albeit lower-resolution, image of global mantle structure. The data set consists of 5401 events and 878,535 P, P (sub n) , pP, sP, and PcP arrivals recorded at 4606 stations. Relocated epicenters are an average of 16 km from bulletin locations. The data set included events that are known to an accuracy of 1 km (a.k.a. GT1) based on nonseismic information. The average distance between GT1 epicenters and our relocated epicenters is 5.6 km. For arrivals labeled P, P (sub n) , and PcP, approximately 92%, approximately 90%, and 96% are properly labeled with probability >0.9, respectively. Incorrect phase labels are found to be erroneous at rates of 0.6%, 0.2%, 1.6%, and 2.5% for P, P (sub n) , PcP, and depth phases (pP and sP), respectively. Labels found to be incorrect, but not erroneous, were reassigned to another phase label. P and P (sub n) residual standard deviation with respect to ak135 travel times are dramatically reduced from 3.45 s to 1.01 s. The differences between travel time residuals for nearly reciprocal raypaths are significantly reduced from the input event locations, suggesting that Bayesloc relocation improves data set consistency. The reciprocity tests suggest that the dominant contribution to travel time residuals calculated from information provided in global bulletins is location and picks errors, not travel time prediction errors due to 3-D structure. Modeling the whole multiple-event system results in accurate locations and an internally consistent data set that is ideal for tomography and other travel time calibration studies. Simmons et al. (2011) (companion paper) use the Bayesloc-processed data set to develop a 3-D tomographic image, which further reduces residual standard deviation to 0.50 s.

The lake is connected to the Mekong River via the Tonle Sap River. Flow in the Tonle Sap River reverses seasonally, with water exiting the lake in the dry season and entering the lake during the summer monsoon. This flood pulse drives the lake's biological productivity. We used Sr, Nd, and Pb isotopes and elemental concentrations in lake sediment cores to track changes in the provenance of deposits in Tonle Sap Lake. We sought to determine when the lake first began to receive water and sediment input via the Mekong River, which initiated flood pulse processes. The transition from a non-pulsing lake to the Mekong-connected system is marked by shifts to values of (super 87) Sr/ (super 86) Sr, epsilon (sub Nd) , and (super 207) Pb/ (super 204) Pb that are characteristic of Mekong River sediments. In addition, magnetic susceptibility increased and sediment elemental composition changed. Elemental (P) measures point to enhanced phosphorus loading and C/N and isotope ratios of bulk organic matter indicate a shift to greater relative contribution of organic material from aquatic versus terrestrial environments, coinciding with the initiation of flood pulse processes. On the basis of radiocarbon dating in two cores, we estimate the initiation of the annual flood pulse occurred between approximately 4,450 and 3,910 cal year BP.

At each of four sites along the eastern Sierra Nevada frontal fault zone between 38 and 39 degrees N latitude, geomorphic markers, such as glacial moraines and outwash terraces, are displaced by a suite of range-front normal faults. Using geomorphic mapping, surveying, and (super 10) Be surface exposure dating, mean fault slip rates are defined, and by utilizing markers of different ages (generally, nearly equal 20 ka and nearly equal 150 ka), rates through time and interactions among multiple faults are examined over 10 (super 4) -10 (super 5) year timescales. At each site for which data are available for the last nearly equal 150 ky, mean slip rates across the Sierra Nevada frontal fault zone have probably not varied by more than a factor of two over time spans equal to half of the total time interval ( nearly equal 20 ky and nearly equal 150 ky timescales): 0.3 + or - 0.1 mm year (super -1) (mode and 95% CI) at both Buckeye Creek in the Bridgeport basin and Sonora Junction; and 0.4 +0.3/-0.1 mm year (super -1) along the West Fork of the Carson River at Woodfords. Data permit rates that are relatively constant over the time scales examined. In contrast, slip rates are highly variable in space over the last nearly equal 20 ky. Slip rates decrease by a factor of 3-5 northward over a distance of nearly equal 20 km between the northern Mono Basin (1.3 +0.6/-0.3 mm year (super -1) at Lundy Canyon site) to the Bridgeport Basin (0.3 + or - 0.1 mm year (super -1) ). The 3-fold decrease in the slip rate on the Sierra Nevada frontal fault zone northward from Mono Basin is indicative of a change in the character of faulting north of the Mina Deflection as extension is transferred eastward onto normal faults between the Sierra Nevada and Walker Lane belt. A compilation of regional deformation rates reveals that the spatial pattern of extension rates changes along strike of the Eastern California Shear Zone-Walker Lane belt. South of the Mina Deflection, extension is accommodated within a diffuse zone of normal and oblique faults, with extension rates increasing northward on the Fish Lake Valley fault. Where faults of the Eastern California Shear Zone terminate northward into the Mina Deflection, extension rates increase northward along the Sierra Nevada frontal fault zone to nearly equal 0.7 mm year (super -1) in northern Mono Basin. This spatial pattern suggests that extension is transferred from more easterly fault systems, e.g., Fish Lake Valley fault, and localized on the Sierra Nevada frontal fault zone as the Eastern California Shear Zone-Walker Lane belt faulting is transferred through the Mina Deflection.

AN - 857809685; 2011-028130 AB - Seismic discontinuities in Earth typically arise from structural, chemical, or temperature variations with increasing depth. The pressure-induced iron spin state transition in the lower mantle may influence seismic wave velocities by changing the elasticity of iron-bearing minerals, but no seismological evidence of an anomaly exists. Inelastic X-ray scattering measurements on (Mg (sub 0.83) Fe (sub 0.17) )O-ferropericlase at pressures across the spin transition show effects limited to the only shear moduli of the elastic tensor. This explains the absence of deviation in the aggregate seismic velocities and, thus, the lack of a one-dimensional seismic signature of the spin crossover. The spin state transition does, however, influence shear anisotropy of ferropericlase and should contribute to the seismic shear wave anisotropy of the lower mantle.

Both clinopyroxene- and olivine-fluid partitioning decrease with increasing temperature (T, K) by the relations: lnD (sub Li) (super cpx/fluid) =-7.3 + or - 0.5+7.0 + or - 0.7 * 1000/T and lnD (sub Li) (super ol/fluid) = -6 + or - 2+6 + or - 2* 1000/T. The lithium partition coefficients increase with pyroxene Al (sub 2) O (sub 3) content and olivine FeO content, and decrease with plagioclase An content. Isotopic fractionation between clinopyroxene and fluid, Delta Li (sub cpx-fluid) , between 900 and 1100 degrees C ranges from -0.3 to -3.5 ppm (+ or - 1.4 ppm). Quantitative modeling of the evolution of lithium concentration and isotopic composition in slab-derived fluids during transport to the arc melt source indicate that fluids migrating by porous flow rapidly exchange lithium with the mantle, effectively buffering the fluid composition close to ambient mantle values, and rapidly attenuating the slab lithium signature. Fluid transport mechanisms involving fracture flow would be required to propagate a slab-like lithium signature (both elemental and isotopic) from the slab to the melt source of island arc basalts.

This initial study considered a faulted aquifer bounded above and below by impermeable rock. We performed a parameter study of fault activation due to elevated pore pressures and addressed several combinations of injection scenarios and in situ stress orientations. The simulations were performed using iteratively coupled flow and geomechanical capabilities. For each scenario, multiple fluid injectors were simulated using a non-steady reservoir flow model while geomechanical analysis predicted the evolving potential for fault reactivation within the reservoir and concomitant permeability evolution. It is observed that the initially considered scenario leads to a loss of containment of fluid from the storage domain. However, alternative scenarios involving either different in situ stress conditions, or modified injection scenarios resulted in successful containment. The results highlight the importance of site selection, site characterization and in situ stress determination when pressure waves from multiple wells and multiple faults interact, and demonstrate the ability of existing tools to help resolve these issues. The results also emphasize that site-specific injection scenarios will be required to manage permitting, deployment, and operations in such a way as to avoid unintended negative consequences, such as large-scale fault activation, related to large-scale deployment.

The SG derived powder was consolidated using the high-pressure spark plasma sintering (HPSPS) technique at 300 and 400 C. The ignition temperatures were investigated under high heating rates (500-2000 C min super(-1)). Such heating rates were required in order to ignite the thermite composite. Samples consolidated at 300 C exhibit an abrupt change in temperature response prior to the main ignition temperature. This change in temperature response is attributed to the crystallization of the amorphous WO sub(3) in the SG derived Ta-WO sub(3) thermite composite and not to a pre-ignition reaction between the constituents. Ignition temperatures for the Ta-WO sub(3) thermite ranged from approximately 465 to 670 C. The activation energies of the SG derived Ta-WO sub(3) thermite composite consolidated at 300 and 400 C were determined to be 38 +/- 2 kJ mol super(-1) and 57 +/- 2 kJ mol super(-1), respectively.

Such models usually rely on simplifications of the geometry and dimensionality of the problem. Detailed three-dimensional flow and transport models, on the other hand, are used which often oversimplify the geochemical reactions. There is a clear need to identify which simplifications and assumptions are admissible. Here we present conceptual and numerical models of radionuclide diffusion and sorption around a HLW repository in clay according to the French reference concept. Models of increasing dimensionality have been performed for: (1) 1D transport perpendicular to the axes of the disposal cells; (2) 1D axisymmetric transport around disposal cells for bounded and unbounded domains; (3) 2D transport through vertical planes; and (4) 1D vertical transport from the disposal cells into the overlying Oxfordian formation. Model results are compared for simulation times up to 10 (super 6) years and for the following radionuclides and tracers: tritium, HTO, which is treated here as an ideal and conservative tracer, (super 36) Cl (super -) which experiences anion exclusion, (super 133) Cs (super +) which sorbs moderately and (super 238) U (IV) which shows a strong sorption capacity. Radionuclides are released into the disposal cell either at a fixed concentration or as an instantaneous unit pulse. Model results indicate that the 1D unbounded model is always acceptable for (super 238) U (IV) and is valid for (super 133) Cs (super +) for t<10 (super 4) years. It is valid for HTO and (super 36) Cl (super -) only for t<10 (super 3) years. These conclusions hold true for both release modes. Computed concentrations with the 1D parallel and the 1D axisymmetric models are significantly different. Inasmuch as solute diffusion in a radioactive waste repository is expected to show radial symmetry around the cells, the use of the axisymmetric model is strongly recommended for the long-term modeling of radionuclide migration from the repository. The 1D vertical model is valid only for conservative radionuclides released instantaneously and leads always to large errors for all radionuclides for a constant concentration.

The relationship between the divertor heat-flux profile and the midplane plasma temperature profile as determined from UEDGE is compared to commonly used predictions from 1D and "2-point" analytic relation. Results show that the parametric variation in lambda(q,div) with midplane separatrix values follows the conduction-limited 2-point model, though the actual value of q(//) on a given flux surface is much lower than implied by the midplane T(e,sep), and lambda(q,div) is - twice as wide as expected from these models. Poloidal variations in chi result in minimal change to radial profiles and probably can't be distinguished experimentally from cases with uniform chi having the same flux-surface average value.

Current can be driven between ends of the flux-tube by passive techniques that generate a thermo-electric potential by heating or cooling one side relative to the other through pumping or neutral gas injection. The induced thermo-electric potential depends on the total particle flux pumped relative to the total recycling flux. For the geometry considered, pumping efficiency is higher for pumping by the target plate or from the private flux zone than for pumping from the outer side of the plate. Neutral gas injection is not as effective at generating an asymmetry. An important constraint for these methods may be the additional heat flux delivered to the hotter target, but additional Ohmic heating is much smaller than that generated by electrical biasing.

Although there is clear indication for their potential role in lignin decomposition processes in soils [3, 4], few reports exist on mechanistic aspects such as substrate specificity, reaction kinetics and oxidizing power of Mn (III)-oxalate complexes reacting with structurally intact plant materials. This is of particular importance in the context of soil organic matter decomposition since lignin cannot be viewed as a single substance [5], but has to be seen as an integral component of ligno-carbohydrate complexes (LCC) in fresh plant cell walls (e.g. in litter, root and wood). Here we tested the hypothesis that Mn (III)-oxalate complexes may act as a 'pretreatment' for structurally intact LCC components in plant cell walls. The diffusible oxidizers are thought to be small enough to penetrate and react with composite LCC in cell walls, thereby increasing porosity which permits access to more efficient lignin- and cellulose-decomposing enzymes. This was investigated by reacting cell walls of single Zinnia elegans tracheary elements with Mn (III)-oxalate complexes in a continuous flow-through micro-reactor. The uniformity of these individual plant cells allowed us to examine Mn (III)-induced changes in cell wall chemistry and ultrastructure on the micro-scale using fluorescence and electron microscopy as well as IR and X-ray spectromicroscopy. This presentation will discuss the specificity of Mn (III)-complexes for certain cell wall functionalities, the impact of such reactions on cell integrity, and potential implications for soil C cycling.

Plutonium (Pu) is of particular concern do to its large worldwide production inventory, high toxicity to human health and long half-life. There is more than 2200 metric tons of Pu throughout the world (ISIS website). The long half-life of Pu ( (super 239) Pu approximately 2.4 X 10 (super 4) years) together with existing inventories guarantees that significant quantities will remain in our environment for a very long time. Effectively managing, controlling, and disposing of these materials in order to stop inadvertent release and transport through the geosphere is a serious scientific challenge. Currently, scientists cannot reliable predict how or how much Pu will move once deposited in the subsurface preventing accurate assessment of risk to human health. The behavior of Pu is complex because the reaction chemistry of Pu (i.e. aqueous speciation, solubility, sorptivity, redox chemistry, and affinity for colloidal particles, both abiotic and microbially-mediated) is particularly complicated. Its migration is known to be oxidation-state dependent and facilitated by transport on particulate matter (i.e. colloidal particles). Yet very little is known about how and under what geochemical conditions colloids facilitate the transport of Pu. Despite the gaps in our understanding, recent field and laboratory experiments are helping to shape our conceptual understanding. I will summarize our current understanding of the biogeochemical processes controlling Pu transport by discussing recent field and laboratory studies. Field studies include weapons facilities where contamination of large quantities of Pu have been deposited and migrated in the subsurface. These studies demonstrate that colloids can and do play an important role in the transport of low-solubility radionuclides; yet, colloids are not always responsible for transport. It is becoming clear that the depositional history of the contamination, as well as the site-specific hydrogeology is critical to assessing the dominant biogeochemical processes controlling the migration of Pu. In addition, the dominant biogeochemical processes controlling migration of Pu can change along the flow path from the source to the far-field environment.

Both types of chondrules show evidence of having been significantly or totally molten. However, these chondrules do not have large or systematic potassium isotopic fractionation of the sort found in the laboratory evaporation experiments. The experimental results reported here provide new data regarding the evaporation kinetics of sodium and potassium from a chondrule-like melt and the potassium isotopic fractionation of evaporation residues run under various conditions ranging from high vacuum to pressures of one bar of H (sub 2) +CO (sub 2) , or H (sub 2) , or helium. The lack of systematic isotopic fractionation of potassium in the type IIA and type IA chondrules compared with what is found in the vacuum and one-bar evaporation residues is interpreted as indicating that they evolved in a partially closed system where the residence time of the surrounding gas was sufficiently long for it to have become saturated in the evaporating species and for isotopic equilibration between the gas and the melt. A diffusion couple experiment juxtaposing chondrule-like melts with different potassium concentrations showed that the diffusivity of potassium is sufficiently fast at liquidus temperatures (DK > 2 X 10 (super -4) cm (super 2) s (super -1) at 1650 degrees C) that diffusion-limited evaporation cannot explain why, despite their having been molten, the type IIA and type IA chondrules show no systematic potassium isotopic fractionation.

Iron sulfides are a major constituent of cometary grains commonly identified within cometary interplanetary dust particles (IDPs) and Wild 2 samples. Chemical analyses indicate Wild 2 sulfides are fundamentally different from those in IDPs. However, as Wild 2 dust was collected via impact into capture media at approximately 6.1 km s (super -1) , it is unclear whether this is due to variation in preaccretional/parent body processes experienced by these materials or due to heating and alteration during collection. We investigated alteration in pyrrhotite and pentlandite impacted into Stardust flight spare Al foils under encounter conditions by comparing scanning and transmission electron microscope (SEM, TEM) analyses of preimpact and postimpact samples and calculating estimates of various impact parameters. SEM is the primary method of analysis during initial in situ examination of Stardust foils, and therefore, we also sought to evaluate the data obtained by SEM using insights provided by TEM. We find iron sulfides experience heating, melting, separation, and loss of S, and mixing with molten Al. These results are consistent with estimated peak pressures and temperatures experienced (approximately 85 GPa, approximately 2600 K) and relative melting temperatures. Unambiguous identification of preserved iron sulfides may be possible by TEM through the location of Al-free regions. In most cases, the Ni:Fe ratio is preserved in both SEM and TEM analyses and may therefore also be used to predict original chemistry and estimate mineralogy.

Shock experiments at 55 GPa were completed on one subsample, and a second subsample was heated in an evacuated quartz tube at 1000 degrees C for 170 h. A third subsample was maintained as a control. Samarium-neodymium, Rb-Sr, 238U-206Pb, and 206Pb-207Pb isotopic analyses were completed on mineral fractions (leached and unleached), leached whole rocks, and complementary acid leachates. Disturbance in the shocked and heated samples was evaluated through comparison of their isochron diagrams with those of the control sample. The Sm-Nd isotope system was the least disturbed, the Rb-Sr isotope system was more disturbed, and the 238U-206Pb and 206Pb-207Pb isotope systems were the most disturbed by shock and annealing. Samples that experienced extended heating demonstrated greater isotopic disturbances than shocked samples. In some cases, the true crystallization age was preserved, and in others, age information was degraded or destroyed. In no case did the experiments generate isochrons that maintained linearity while being rotated or completely reset. Although our results show that neither experimental shock nor thermal metamorphism alone can account for the discordant ages represented by different isotope systems in some Martian meteorites, we postulate that shock metamorphism may render a meteorite more susceptible than its unshocked counterpart to subsequent disturbance during extended impact-related heating or aqueous alteration. The combination of these processes may result in the disparate chronometric information preserved in some meteorites.

Details about diamond-to-graphite transition occurring during subsequent exhumation are not well understood. Because the structures of diamond and graphite are so dissimilar, it is unlikely that a direct phase transformation would occur in the graphitization process. Heating experiments at T=1500-1800 degrees C and ambient pressure showed that diamond is replaced by disordered graphite along planes with a high concentration of dislocations. In order to better understand the process of diamond-to-graphite transformation we measured C, and N isotopes in an inclusion, comprising graphite with a diamond core, in zircon from the Kokchetav massif, Kazakhstan. The inclusion is approximately 10 mm in diameter and consists of a approximately 3 mm diamond core that is surrounded by a graphite rim approximately 7 mm in thickness. The C and N isotopes were measured with a Cameca NanoSIMS-50. Diamond and graphite in the inclusion are isotopically indistinguishable (i.e. D (super 13) C (sub diamond-graphite) and D (super 15) N (sub diamond-graphite) nearly equal 0). The C and N isotopic composition for the entire inclusion is d (super 13) C = -30 + or - 1 ppm and d (super 15) N = +0.5 + or - 3 ppm respectively, which is in the range of carbon of organic origin. The distinctive geometry of the diamond-graphite inclusion - the diamond core mantled by graphite - suggests a retrogressive reaction that probably occurred due to decompression during the host rock's exhumation to the Earth's surface from depths > 120-150 km. The lack of intra-mineral isotope fractionation between diamond and graphite for both C and N isotopes suggests that the retrogressive diamond-to-graphite transformation occurred at temperatures above 500 degrees C and pressures less than 4 GPa. Raman spectroscopy studies of this diamond by Smith et al. (2011) show the presence of 1624 -1647 cm-1 bands which are close to those of disordered graphite. We thus hypothesize that during exhumation diamond was gradually replaced by graphite through an intermediate phase of disordered graphite.

Preliminary data from these studies indicate that soil samples collected along historical fallout plumes contain easily accessible information about key components of each test such as fuel isotopics and the elemental composition of structural components. The distribution of fuel, activation product and fission product signatures as a function of soil grain size and distance from ground zero has been found to be nearly uniform among larger grain sizes of fallout soil (>0.1 mm). Anthropogenic glasses extracted from the fallout soil samples constitute 50% of the total activity. Order of magnitude increases in the concentrations of actinides such as (super 235) U or (super 239) Pu are observed in the glass relative to the soil. By gamma spectroscopy (super 235) U concentrations are estimated to be >60 mg/g and (super 239) Pu concentrations >20 mg/g in glasses recovered from two different tests. Preliminary analysis of the U bearing glasses by ICP-MS indicates a fuel with a minimum enrichment of 84% (super 235) U. Analysis of the stable isotope signal from ICP-MS measurements shows that Be is present in the glass at concentrations 4 times higher then the bulk soil, and that Cr, Co and Mo are present in the U bearing glasses at 3-20 times the bulk soil concentration. These results demonstrate that fallout from low yield surface nuclear tests collected as surface deposits long after the detonation contains valuable information about device characteristics. This information is relevant to characterizing historical activities from surface based nuclear test programs and is applicable to nuclear forensics research.

A contemporary global background cycle is first constructed, within the framework of the Parallel Ocean Program. Input from organics in the upper thermocline is related to oxygen levels, and microbial consumption is parameterized from available rate measurements. Seepage into bottom layers is then superimposed, representing typical seabed fluid flow. The resulting CH (sub 4) distribution is validated against surface saturation ratios, vertical sections, and slope plume studies. Injections of clathrate-derived methane are explored by distributing a small number of point sources around the Arctic continental shelf, where stocks are extensive and susceptible to instability during the first few decades of global warming. Isolated bottom cells are assigned dissolved gas fluxes from porous-media simulation. Given the present bulk removal pattern, methane does not penetrate far from emission sites. Accumulated effects, however, spread to the regional scale following the modeled current system. Both hypoxification and acidification are documented. Sensitivity studies illustrate a potential for material restrictions to broaden the perturbations, since methanotrophic consumers require nutrients and trace metals. When such factors are considered, methane buildup within the Arctic basin is enhanced. However, freshened polar surface waters act as a barrier to atmospheric transfer, diverting products into the deep return flow. Uncertainties in the logic and calculations are enumerated including those inherent in high-latitude clathrate abundance, buoyant effluent rise through the column, representation of the general circulation, and bacterial growth kinetics.

The determination of PRs for extraterrestrial samples, on the other hand, utlizes samples that have achieved secular equilibrium during long exposure in a low erosion environment. Here we adopt this approach to derive terrestrial cosmogenic (super 10) Be and (super 26) Al production rates. Sets of paired (super 10) Be- (super 26) Al results were selected from our published and unpublished data (28 Antarctica, 45 Atacama Desert). All samples contain more than 4X10 (super 6) atoms (super 10) Be/g quartz, sea level at high latitude. The (super 10) Be concentrations were plotted against corresponding (super 26) Al/ (super 10) Be values, and a range of possible 'saturated' (super 10) Be production rates. A (super 10) Be production rate (P (sub 10) ) of 5.1-5.3 atom/yr g-quartz is the best fit to the measurements. This P (sub 10) is much higher than the recently proposed P (sub 10) of approximately 4.5. Known geologic processes cannot reconcile these two production rates. In fact, the P (sub 10) based on Atacama and Antarctic samples is a minimum production rate since: (1) samples must have experienced some erosion and even 5 cm/Myr erosion yields a 16 % P (sub 10) increase; (2) any soil, ash or snow cover would artificially depress our PR estimate; (3) saturation may not have been achieved, since for many samples (super 26) Al- (super 21) Ne exposure ages do not show more than 8 Myr exposure age (98% saturation for (super 10) Be); (4) uplift of the Transantarctic Mountains and Atacama Desert moves the samples into higher PR. The high P (sub 10) indicates that the long-term cosmic ray flux is higher than that of the last few tens of thousands of years, probably due to a higher GCR flux and lower geomagnetic field in the past.

Using an InSAR time-series analysis method, we show that an increase in absolute uplift with time is observed between 1997 and 1999. The signal is collocated with past underground nuclear tests. Due to the collocation in space with past underground tests we postulate a nuclear test-related hydrothermal source for the uplift signal. A possible mechanism is presented that can account for the observed transient uplift and is consistent with documented thermal regimes associated with underground nuclear tests conducted at the Nevada National Security Site (NNSS) (formerly the Nevada Test Site).

Many moraines have been dated although the number of samples on each moraine vary widely and may often be too small to assess the true geological scatter of the dated landform. Here we present cosmogenic age distributions for moraines of Tibet and present various explanations to explain the shape of the distributions for moraines dated with large numbers of samples. While it is true that the more samples are dated the more complexity may arise just by adding more information to the data set, it is also true that by targeting to few samples complex depositional or post-depositional processes may be completely overlooked. We focus on moraines deposited in comparable glacial setting from the last glacial maximum and before, and will show that similar geomorphologies are not necessarily correlated with age but most probably to similar glacier ice dynamics. Distributions of ages need to be explained by some independent assessment of depositional or post-depositional model, that can be further tested by the addition of observations, such as, for instance, the relative ages of inset moraines, or the amount of cummulated tectonic offset when available. True and independent moraine age assessments are preferable whenever possible, but it is noticeable that some patterns of ages can be recognized over large sets of data covering large areas of Tibet that argue for at least some synchronous glacial advances and moraine retreats, that with no surprise do correlate with global climate variations.

Concentrated in the central Ukrainian shield, these ore bodies ( approximately 1, 8 Ga, inferred from U-Pb analyses [1]), are associated with albitites in granites. Carbonates, iron oxides and Ca-Fe garnets are found genetically associated with uranium minerals, while albite and other alkali silicates formed during earlier stage metasomatic processes. Albite has been altered at the margins adjacent to the uranium minerals from low to high albite. We present preliminary work characterizing primary uranium ores in Ukraine, as part of a larger effort to develop a database of nuclear materials for Ukraine. We have studied uranium minerals from representative samples of the Severinskoje (I), Michurinskoje (II), and Vatutinskoje (III) deposits, as well as from the Adabash fracture zone mineralization (IV), using mineralogy and gamma spectrometry [2]. This study presents new X-ray diffraction (powder and single grains), SEM and TEM characterizations, and microprobe study of the principal U-minerals present: Uraninite (IV), a (sub 0) =0, 542 nm, forming cubic crystals up to 0, 5 mm. Average composition is Na (sub 2) O 5, 6%; SiO (sub 2) 0, 8%; CaO 1, 74%; PbO 23%; U (sub 3) O (sub 8) 72, 4%. U, Ca, Pb appear to be associated with the host crystal matrix, while Na, Si and trace elements are concentrated in solid inclusions (up to 0, 5 mm). Coffinite (I, II, III) forms elongated crystals up to 0, 1 mm. Average composition is Al (sub 2) O (sub 3) 0, 9%; SiO (sub 2) 15%; CaO 2, 5%; Fe (sub 2) O (sub 3) 1, 4%; U (sub 2) O (sub 3) 65%. Brannerite (II, III) forms elongated, needle-like crystals up to 0, 1 mm. Average composition is PbO 6, 17%; UO (sub 2) 39, 18%; CaO 3, 15%; SiO (sub 2) 2, 31%; TiO (sub 2) 24, 49%; FeO 2, 08%. This mineral occurs intergrown with an unknown silicate mineral (mixture) with composition approximately (Ca, Pb, U)(Ti, Fe) (sub 2) Si (sub 3) O (sub 11) . Ca-Uraninite (I) approximately CaU (sub 2) O (sub 6) , is cubic, a (sub 0) = 5, 37 nm. This is possibly a new mineral variety. It forms in thin veins ( approximately 20 um thick) and globules ( approximately 1 um). Ca-boltwoodite (I) occurs as thin veins of plate-like crystals up to 20 um in diameter. The boltwoodite powder XRD pattern suggests a disordered layered structure, possibly representing a new mineral variety. The relative composition is U:Si:(Na+K+Ca (sub 0, 5) ) approximately 1:1:1.

Of particular relevance is elucidating the Greenland Ice Sheet's response to decadal- and centennial-scale climate change. Here, we reconstruct the early Holocene history of Jakobshavn Isbrae, Greenland's largest outlet glacier, using (super 10) Be surface exposure ages and (super 14) C-dated lake sediments. Our chronology of ice-margin change demonstrates that Jakobshavn Isbrae advanced to deposit moraines in response to abrupt cooling recorded in central Greenland ice cores ca. 8,200 and 9,300 years ago. While the rapid, dynamically aided retreat of many Greenland outlet glaciers in response to warming is well documented, these results indicate that marine-terminating outlet glaciers are also able to respond quickly to cooling. We suggest that short lag times of high ice flux margins enable a greater magnitude response of marine-terminating outlets to abrupt climate change compared to their land-terminating counterparts.

This is problematic for highly insoluble species such as Pu(IV), where little direct information is available on its chemical behavior at environmental conditions. To this end, ab initio simulations are potentially useful for gaining insights into Pu complexes in aqueous environments. However, the electronic structure of actinide complexes poses difficulties. Accurate treatments of actinides often require sophisticated correlated wavefunction techniques whose cost grows rapidly with the number of electrons, and are only practical for small systems. Large-scale dynamical simulations of condensed phase phenomena typically rely on density functional theory (DFT); however, current DFT approximations for exchange-correlation (E (sub xc) ) can yield large errors for actinides due to the presence of localized 5f-electrons. We report benchmark studies for the monomeric Pu(OH) (sub 4) complex employing a range of ab initio techniques including single-reference approaches (unrestricted Hartree-Fock, UHF; second-order Moller-Plesset perturbation theory, MP2), multi-reference approaches (complete active space self-consistent field method, CASSCF; multi-reference perturbation theory, MRPT) and DFT. We find that single-reference methods such as MP2 provide a reasonable description of ground state geometries and energies, and an explicit inclusion of multi-reference effects involving the Pu 5f electrons is not essential. However, DFT with standard approximations for E (sub xc) performs poorly for Pu(OH) (sub 4) . We explore the use of DFT+U as a simple way to improve on the DFT description of on-site Pu 5f-electron correlations. Using small hydrated cluster models, Pu(OH) (sub 4) (H (sub 2) O) (sub n) , we determine an ab initio parameterization of DFT+U suitable for the aqueous phase simulation of Pu(OH) (sub 4) . With this DFT+U parameterization, we carry out periodic, ab initio molecular dynamics simulations of Pu(OH) (sub 4) in a bulk water environment, in order to determine the aqueous solvation structure around Pu(OH) (sub 4) .

For diffusion in liquids, there is no general theory that relates cation diffusivity to mass, but mass discrimination during diffusion must be affected by the nature of cation-solvent interactions. To investigate the relationship between liquid structure and cation diffusion, we measured Ca and Mg isotope diffusivities in silicate liquids using diffusion couples of natural and synthetic compositions. In all experiments, the initial isotopic composition is uniform and each isotope diffuses in the same direction down a substantial concentration gradient, enriching the Ca- or Mg-poor liquids in the lighter isotope by an amount dependent on: (1) the initial concentration contrast between liquids, (2) the relative chemical diffusivities of isotopes, and (3) the efficiency of isotopic exchange or self diffusion superimposed on chemical diffusion. Results from these experiments, in combination with results from natural volcanic liquids, show clearly that the efficiency of isotope separation (E) is systematically related to the solvent-normalized diffusivity - the ratio of the diffusivity of the cation (D (sub cation) ) to the diffusivity of silicon (D (sub Si) ). We present an idealized quantitative model to explain the relationship between E and D (sub cation) /D (sub Si) . The model views cation diffusion as a combination of two (or possibly more) distinct mechanisms of transport: "free" cations that site-hop among aluminosilicate structures, and "bound" cations that translate or rotate with aluminosilicate structures in the melt. We assume that the rate of exchange between free and bound cations is infinitely fast to maintain local equilibrium. In this model, the observed or net diffusivity and its mass dependence are determined by the relative abundance (K) of free versus bound cations in the liquid. This conceptualization provides a framework for describing mass discrimination in complex liquid systems and for understanding the role of diffusion in contributing to stable isotope variations in minerals.

Exercises have been conducted to increase our preparedness and response capabilities to chemical, biological, radiological, and nuclear (CBRN) terrorist attacks. However, incorporating forensic components into these exercises has been deficient. CBRN investigations rely on forensic results, so the need to integrate a forensic component and forensics experts into comprehensive exercises is paramount. This article provides guidance for planning and executing exercises at local, state, federal, and international levels that test the effectiveness of forensic capabilities for CBRN threats. The guidelines presented here apply both to situations where forensics is only a component of a more general exercise and where forensics is the primary focus of the exercise.

One composite was synthesized using a sol-gel (SG) derived method in which micrometric-scale tantalum is immobilized in a tungsten oxide three-dimensional nanostructured network structure. The second energetic composite was made from the mixing of micrometric-scale tantalum and commercially available (CA) nanometric tungsten oxide powders. The energetic composites were consolidated using the spark plasma sintering (SPS) technique under a 300 MPa pressure and at temperatures of 25, 400, and 500 C. For samples consolidated at 25 C, the density of the CA composite is 61.65 +/- 1.07% in comparison to 56.41 +/- 1.19% for the SG derived composite. In contrast, the resulting densities of the SG composite are higher than the CA composite for samples consolidated at 400 and 500 C. The theoretical maximum density for the SG composite consolidated to 400 and 500 C are 81.30 +/- 0.58% and 84.42 +/- 0.62%, respectively. The theoretical maximum density of the CA composite consolidated to 400 and 500 C are 74.54 +/- 0.80% and 77.90 +/- 0.79%, respectively. X-ray diffraction analyses showed an increase of pre-reaction of the constituents with an increase in the consolidation temperature. The increase in pre-reaction results in lower stored energy content for samples consolidated to 400 and 500 C in comparison to samples consolidated at 25 C.

Previous investigations of the Kern Canyon fault underscore its importance as a Late Cretaceous and Neogene shear zone in the tectonic development of the southern Sierra Nevada. Study of the late Quaternary history of activity, however, has been confounded by the remote nature of the Kern Canyon fault and deep along-strike exhumation within the northern Kern River drainage, driven by focused fluvial and glacial erosion. Recent acquisition of airborne lidar (light detection and ranging) topography along the approximately 140 km length of the Kern Canyon fault provides a comprehensive view of the active surface trace. High-resolution, lidar-derived digital elevation models (DEMs) for the northern Kern Canyon fault enable identification of previously unrecognized offsets of late Quaternary moraines near Soda Spring (36.345 degrees N, 118.408 degrees W). Predominately north-striking fault scarps developed on the Soda Spring moraines display west-side-up displacement and lack a significant sense of strike-slip separation, consistent with detailed mapping and trenching along the entire Kern Canyon fault. Scarp-normal topographic profiling derived from the lidar DEMs suggests normal displacement of at least 2.8 +0.6/-0.5 m of the Tioga terminal moraine crest. Cosmogenic (super 10) Be exposure dating of Tioga moraine boulders yields a tight age cluster centered around 18.1+ or -0.5 ka (n=6), indicating a minimum normal-sense fault slip rate of approximately 0.1-0.2 mm/yr over this period. Taken together, these results provide the first clear documentation of late Quaternary activity on the Kern Canyon fault and highlight its role in accommodating internal deformation of the southern Sierra Nevada.

The aquitard is characterized by fine-grained glacial till matrix with sand and gravel lenses, where the "drift gas" accumulates. Noble gas concentrations from the underlying aquifer indicate the groundwater has been degassed at some point. It is believed that as total dissolved gas pressure increases, due to actively occurring methanogenesis within organic rich, buried paleosols, hydrostatic pressure is exceeded and methane and other dissolved gases are exsolved from solution. It is hypothesized by using the NUFT code the model will be able to constrain the amount of groundwater infiltrating through the aquitard by simulating the production of these "drift gas" pockets. An atmospheric neon source component is included in the model in order to simulate the noble gas loss observed in underlying aquifer. The model output will be calibrated to known gas composition (methane, nitrogen, and all noble gases) in the drift gas and associated dissolved groundwater concentrations, and to hydraulic head values. Parameters to be varied include recharge rate, methane production rate, and hydraulic conductivities of the till matrix and sand and gravel features. A preliminary model has shown that the majority of methane produced in the paleosol zone is transported downwards in its dissolved phase until it reaches the sand/gravel lenses, where it is then released into free gas phase. This is in agreement with radiocarbon data on drift gas samples that suggests the source of the methane is younger than the depth at which it is found. The drift gas produced is about 70% methane with air and a small amount of neon comprising the rest. Drift gas composition varies, but the majority of samples contain between 70 to 90 percent methane. Preliminary findings show that dissolved methane transport and exsolution are very dependent on a sensitive relationship between recharge and methane production rates. In addition to constraining recharge through the aquitards, this model could quantitatively assess methane production rates and time scales for production of drift gas pockets.

In turn, a groundwater basin, or group of basins, can be characterized by evaluating classified age from a set of representative samples. If > or = 50% of the samples are in a single age class, the basin is defined strongly by that class. If the number of samples in one age class is larger than the others, but or = 0.2 TU) or pre-modern ( or = 97), young (97> pmc > or = 80), or old (pmc or = 3% of total (super 4) He). The thresholds were chosen to minimize classification conflict (because not all samples were analyzed for (super 14) C). Classified age then was assigned to a sample based on all 3 tracers, if available, or on 2, if not. Of the 1513 samples: 460 were modern, 575 were mixed, 449 were old, and 29 lacked sufficient data. Also, 7 study units were modern (1 strongly), 6 were mixed modern, 5 were mixed old, and 5 were old (2 strongly). Two study units were mixed but with equal numbers of modern and old samples. Study units characterized as modern or mixed modern were in areas where groundwater is broadly and intensively used for urban or agricultural supply. Study units characterized as old or mixed old were in areas where groundwater is not as extensively used, particularly in the desert. This study shows that age-dating of samples from long-screened production wells provides meaningful information at the basin scale; this information can be used for other purposes such as evaluation of groundwater quality.

Analyses of this extensive dataset provide a means to investigate the influence of geologic age, lithology, and tectonic structures on the spatial variability of (super 3) He/ (super 4) He in California groundwaters. Previous work identified mechanisms that introduce (super 3) He (magmatism, seismicity) and (super 4) He (erosion, in situ and deep crustal production). Preliminary data analyses show that (super 3) He/ (super 4) He, corrected for air-entrainment, ranged from 0.01 R (sub A) to 5.10 R (sub A) (R (sub A) is the (super 3) He/ (super 4) He of air 1.4 X 10 (super -6) ). To identify sources of (super 3) He and explain variations in the (super 3) He/ (super 4) He statewide, the geology mapped at the well and the well's proximity to faults were investigated. Nonparametric statistics were used to test for correlations between (super 3) He/ (super 4) He and potential explanatory factors. The correlation between (super 3) He/ (super 4) He and the categorical explanatory factors: rock type (sedimentary, plutonic, volcanic), geologic Era (Cenozoic, Mesozoic, pre-Mesozoic), Cenozoic age (Holocene, Pleistocene, Tertiary), and Cenozoic sediment type (alluvium, glacial, marine, non-marine, sand, volcanic) were evaluated with the Wilcoxon rank-sum test. The Spearman's method was used to establish correlation between the continuous variables (super 3) He/ (super 4) He and the distance of a well to the nearest fault. Statistical tests demonstrate that (super 3) He/ (super 4) He had a significant positive correlation to the proximity of a well to faults. There also are significant differences in (super 3) He/ (super 4) He between the following categorical factors: higher in volcanic than in plutonic rocks; higher in plutonic than in sedimentary rocks; higher in Cenozoic than Mesozoic rocks; and higher in pre-Mesozoic than Mesozoic rocks. These results, higher (super 3) He/ (super 4) He in wells located in volcanics and rocks of Cenozoic age, may be explained by mantle (super 3) He from relatively recent magmatic activity. The increase of (super 3) He/ (super 4) He near faults suggests seismic activity as a source of (super 3) He. Other statistical comparisons revealed no significant correlations. Identifying the factors that explain the spatial variations in (super 3) He/ (super 4) He is the first step towards characterizing groundwater affected by seismic activity, (super 3) He from tritium decay, long residence times, and crustal degassing.

The geological structure, as well as many physical and chemical properties, controls the concentration profile of gas components at and near ground surface. The detectability of gas components is characterized by (1) arrival time; (2) detection window width; and (3) detection window height (above the detection threshold). The arrival time is defined as the time when the concentration of a gas component reaches its detection threshold. The detection window width is the time duration between the arrival time and the time when the concentration drops below the threshold by radioactive decay. The detection window height is measured as the order of magnitude of the peak concentration higher than the threshold. The physical model is conceptualized as a dual permeability presentation of overlapping fracture and matrix continua. The fracture system is characterized by its frequency, aperture size, permeability, and orientation. In this study, we use numerical simulation of non-isothermal multi-phase and multi-component transport to investigate how gas components release and transport in fractured rock system. Taking those four fracture parameters as uncertain parameters in the model of gas transport, we describe the use of uncertainty quantification software called PSUADE to investigate the role of uncertain parameters in the detectability of gas components. As demonstrated in the applications, sensitivities of detectability characteristics in terms of fracture parameters are provided.

The South American Andes represent the classic orogenic setting of oceanic-continental collision, yet the most fundamental processes that control the generation of high topography are still poorly understood. Quantifying exhumation rates in orogenic settings is an important way to assess the nature of rock uplift and when combined with techniques that measure the degree of surface modification (i.e. in situ produced radionuclides) can be used to develop records of surface uplift. In this study, we present three new zircon and apatite (U-Th)/He age-elevation transects from the northern Peruvian Andes. By using both apatite and zircon we are able to constrain temporal changes in the rates of exhumation at three different locations spanning two degrees of latitude ( approximately 6.5 degrees S to approximately 8.5 degrees S). In the most northern field site, located on the Rio Maranon, our results indicate very slow exhumation from the Mesozoic to the Miocene. Since the mid-Miocene, exhumation has increased to a constant rate of approximately 0.3mm/yr. The southern location is within the Western Cordillera and our data show an exhumation rate of approximately 0.05mm/yr during the Miocene and a recent, rapid increase to approximately 2mm/yr since the Pliocene. This study presents the first data of this kind from this region and supports the notion of a significant acceleration in exhumation from Miocene time to the present. Prior studies in the central and northern Peruvian Andes have suggested a tectonic history consisting of five or more short, compressive pulses of activity separated by longer periods of quiescence or extensional stress (Megard et al., 1984; Noble et al., 1985, 1990; McKee and Noble, 1982; Wise et al., 2008). However, it is unclear if and/or how the most recent tectonic pulse ( approximately 8.7Ma; Wise et al., 2008) that has been identified is related to the increase in exhumation our data show. Instead, an increase in climate-driven erosion during the late Miocene-Pliocene may be responsible for the acceleration in exhumation rate we document here.

The WIPP (Waste Isolation Pilot Plant) geochemistry model (e.g., Xiong, 2005) is a Pitzer-based model built around the Harvie et al. (1984) model of the "sea salt" system. The WIPP model was developed for use with the FMT code (Babb and Novak, 1995). Recently it became desirable to port the model to EQ3/6 (e.g., Wolery and Jarek, 2003), which has been employed on the Yucca Mountain Project. The FMT thermodynamic database was translated into a format used by EQ3/6. Results from the two codes were then compared for a set of 14 test problems. Some expected differences resulted from the fact that FMT, unlike most geochemical codes, requires initial brines to be described in terms of elemental mole numbers (including contributions from the solvent, water). In contrast, EQ3/6 requires initial brines to be described in terms of parameters (usually molalities and pH) for a set of "basis" species. Differences can also result from different ways of adjusting for charge balance. Some unexpected differences were observed. These were traced to (1) the use in FMT of 0.39 as the value for the Debye-Huckel A (sub phi ) parameter instead of the correct 0.392, (2) the use in FMT of an older approximation (Pitzer, 1975) for the J(x) function instead of the later Harvie (1981) approximation, and (3) a difference in how the two codes handle missing values of the psi parameter for cc'a and aa'c ion triplets. EQ3/6 was modified to handle missing psi values in the more conventional manner used by FMT and to allow the use of the older J(x) approximation as an option (the WIPP density model was also added at this time). EQ3/6 can use the 0.39 value of A (sub psi ) by specifying that on the thermodynamic data file. By accounting for all of these factors, EQ3/6 and FMT produce essentially identical results, despite the fact that the codes use substantially different numerical methods. The effect on the WIPP geochemistry model of using the correct A (sub psi ) value and the Harvie (1981) approximation for J(x) was examined and found not to sensibly affect results of concern to WIPP performance assessment. This is due to the fact that the dominant radionuclide species have relatively low charge numbers.

Bedrock/boulder pairs were collected from six locations over a distance of 40 km, stretching from the sea to the present-day ice margin. These samples were taken at a variety of elevations at each location, ranging between 50 and 620 m a.s.l. This "dipstick" sampling method provides a three-dimensional perspective on the characteristics of ice retreat and erosion efficiency. In general, the ages of bedrock and boulder samples are in close agreement. Almost all sample pairs are indistinguishable at one-sigma, and the two populations are not separable. This indicates that subglacial erosion rates are sufficient to remove virtually all (super 10) Be from previous periods of exposure, suggesting that the ice in this area is warm-based and highly erosive during glacial periods. This pattern is seen at both low and high elevations, suggesting similar erosion rates regardless of ice thickness. This trend demonstrates that, as opposed to many other locations in the Arctic, most bedrock near Jakobshavn does not contain inherited (super 10) Be and should accurately record deglaciation age. Therefore, cosmogenic bedrock dating performed in this area by Briner and Young is robust. Only two bedrock samples from our dataset are appreciably older than their corresponding boulder samples, showing that small amounts (<1 ka worth) of inheritance may be present in isolated locations. There is a strong decreasing trend in age with decreased distance from the present-day ice margin. Samples from the coast indicate that deglaciation occurred approximately 9 ka BP, while samples from the margin indicate a significantly younger deglaciation age of approximately 6.5 to 7 ka BP. This pattern suggests that ice retreated slowly and regularly across the landscape, progressively exposing rock that had previously been shielded. Our data show that about 40 km of retreat occurred over a period of 2 to 2.5 ka, indicating retreat rates of 15-20 m yr (super -1) .

The injection continues 5 years and then stops. 5 years after the injection, the pH around the injection well drops to 3.9 (background pH is 5.6). 100 years after the CO<2) injection, the plume of gas phase CO<2) still maintain around the injection well. 500 years later, the plume of CO<2) extends and can spread to another plume of injection CO<2) . Because the decrease of pressure, the plume of pH almost maitains after 500 years, even though the plume of CO<2) moves.

The results of reactive transport modelling provide valuable insights for analyzing the behavious of injected CO<2) and assessing the storage sites.

The Antarctic Cold Reversal (ACR) in the southern polar hemisphere was contemporaneous with the Bolling-Allerod and ended during the peak of the Younger Dryas, but its causes remain obscure. Recent work has suggested the existence of hemispherical teleconnections and feedbacks between the northern ice sheets and the atmosphere-ocean system, affecting thermohaline circulation and planetary wind belts, as well as atmospheric CO2 concentrations and global deglacial climate. Determining if the ACR cooling was regional, hemispherical or global in extent is a prerequisite for understanding the causes behind it. Four main moraine belts (TDP I-IV, from outer to inner) expose geomorphological evidence for ice extent and fluctuations during the last glacial cycle in Torres del Paine National Park (TDP, 51 degrees S, southern Chile). We collected 38 boulders embedded in the inner three moraines (TDP II-IV moraines) for 10Be cosmogenic-exposure dating and thereby reconstructed local late Quaternary glacial and climate history. The 10Be exposure data show that the mean ages of these three moraines are statistically indistinguishable at 1sigma uncertainty; we infer that they were deposited during the same glacial episode, culminating at 14.0 ka BP (ka BP = 1,000 years before present). The late-glacial age of the TDPII-IV moraines has important implications. First, the glaciers in TDP region were far (>40 km) from the present-day ice margin at approximately 14.0 ka BP, during the ACR chronozone. Second, the approximately 14.0 ka BP glacial pulse was as nearly as extensive as the advance represented by the prominent TDP I moraine, thought to be early or pre-LGM. This extensive glacier pulse at approximately 14.0 ka BP suggests that the southern westerlies may have been centered at or very close to TDP (51 degrees S), which prompted enhanced snow accumulation during winter months and reduced incoming solar radiation during summer.

Potential benefits include a source of usable water and a reduced Area of Review. A necessary factor (examined here) is that is that the displaced brine must be treatable by desalination. Treatment becomes more difficult with increasing Total Dissolved Solids (TDS), which ranges from a lower (regulatory) limit of 10,000 mg/L up to about 400,000 mg/L. Specific brine composition matters, but is less significant. We calculated the result of removing water from various brine compositions, simulating reverse osmosis (RO), focusing on mineral precipitation and increasing osmotic pressure of the residual brine. The rise in the latter is more limiting on practical water extraction. Brines with TDS in the range 10,000-40,000 mg/L TDS are prime candidates for RO treatment, using a process much like that for seawater. Brines with TDS in the range 40,000-85,000 mg/L TDS may be treatable by RO alone, but with lower recovery. Above 85,000 mg/L, less conventional methods are necessary, such as NF (nanofiltration) + RO or multi-stage RO. Above 300,000 mg/L TDS, brines are probably untreatable. We used the U.S.G.S. Produced Waters Database (Breit, 2002) to look at the distribution of TDS and brine composition with depth over various geographic regions (mainly at the state level). A depth of 800 m (2625 ft.) or more is required to maintain CO2 in the supercritical state. Between that depth and about 11,000 ft., there is in general (at the national level) only a small tendency for TDS to increase with depth. In some locales, TDS decreases. Thus, injecting at greater depth does not generally lead to less treatable brine. Data for various western states (e.g., Colorado, Wyoming, California) show substantial fractions of brine in the 10,000-85,000 mg/L TDS range, indicating that active management is feasible, insofar as the brine composition is concerned. The situation is not so attractive in some other states (e.g., Mississippi, Illinois), where the brines are much saltier. Substantial opportunities remain to analyze subsurface brine data using the U.S.G.S. database and its larger cousin, the NATCARB database.

Although the FP ceased to exist on the surface, it continues to have a significant tectonic impact on North America. The subducted FP continues to drive a large-scale convective cell below the southern extent of North America, where downward flow in the east is driven by the deep dense Farallon slab and the upward return flow in the west is enhanced by a region of warm mantle beneath the southwestern US [Moucha et al., 2008; 2009]. Herein, we reconstruct the temporal evolution of this flow from a global backward-in-time mantle convection simulation starting with present-day heterogeneity derived from a high-resolution joint seismic-geodynamic global tomography model [Simmons et al., 2009]. A significant result of the joint seismic-geodynamic inversions is that the inferred seismic wave speed to density scalings vary in all three dimensions and thus contain the crucially important effects of intrinsic changes in mantle chemistry and possible partial melting on density. The final density model provides an excellent fit to present-day global geodynamic observables while preserving excellent fit to global seismic data. Additionally, the convection simulation incorporates Newtonian rheology with a viscosity profile that is constrained by global joint inversions of convection-related surface observables and data associated with the response of the Earth to ice-age surface mass loading [Mitrovica and Forte, 2004]. We quantify the effects of this reconstructed flow on the southwestern US tectonics, including the uplift of the Colorado Plateau (CP) and adjacent regions over the last 30 Ma, by presenting a time-dependent numerical model of topography that is supported by convectively maintained vertical stresses generated by the flow in the mantle, termed dynamic topography. We show that: (1) the extension and basaltic volcanism (post 25 Ma) in the central Basin & Range coincides with the arrival and eastward progression of mantle upwelling, and (2) dynamic uplift of the southern CP, totalling about 1 km, transpired in the last 20 Ma. Since 10 Ma, the center of uplift continued northeastward from the southwestern rim of the plateau consistent with a young Grand Canyon model and eastward sweep of magmatism in the CP.

Considerable recent interest has focused on the potential role of dynamic topography arising from buoyancy driven flows in the mantle and their potential effects on interpretations of long-term sea level. We focus on the Pliocene, specifically the various transgressive units that onlap unconformably across the coastal plain in VA, NC, SC, GA, and northern FL. In northern GA, across SC, and southern NC marine facies of the Duplin Fm extend westwards up to at least the Orangeburg Scarp where these strata attain elevations in excess of about 100 m, increasing towards the N. The northward continuation of the Orangeburg Scarp and the Duplin are erosionally truncated, making it impossible to trace the maximum heights farther north across northern NC and southern VA. Farther north in VA the Yorktown onlaps over the Fall Line and attains elevations in excess of 80 m at this southward facing erosional edge. Farther north the Yorktown zero edge swings east around MD and only younger Pliocene Beaverdam estuarine sediments are preserved in DE at low elevations (<30 m), and farther north in NJ marine Pliocene sediments are preserved only at very low elevations (<10 m) near Cape May. In all areas, this surface slopes toward the modern coast. The complex topography along the Pliocene flooding surface requires significant along strike and across strike differential vertical motions. Vertical motions arising from dynamic topography, flexural loading offshore, erosion-related flexural unloading onshore, together with glacial isostatic responses are incorporated in our analysis. We find considerable support for our recent dynamic topography models in which density contrasts in the upper mantle give rise to significant vertical motions, both uplift and subsidence along the eastern seaboard of the U.S. since the Pliocene, and directly contrary to other models that show only dynamic topographic subsidence.

Comparison of these data, derived from geologic, geomorphic, and paleoseismic records, with geodetic estimates of fault loading affords unparalleled opportunity to investigate the dynamics of earthquake processes and the evolution of an intracontinental plate boundary fault system. We focus here on the Little Lake fault, which occurs along the western margin of the ECSZ between the Sierra Nevada and the Coso Range in east-central California. The fault accommodates between 10-20% of the total dextral motion within the ECSZ at this latitude and a smaller fraction of the relative motion between the Pacific and North American Plates. Relatively high rates of decadal fault loading described for the Little Lake fault zone from GPS measurements and InSAR data suggest potential discrepancies with longer, late Quaternary records of geologic strain. To address this inconsistency, we targeted a series of fluvial terraces related to overtopping and outflow from pluvial Owens Lake that cross the fault and record dextral offset since late Pleistocene time. High-resolution topographic surveying using a tripod-mounted laser scanner suggests between 33 and 38 m of reconstructed right-lateral displacement of two individual terrace risers over this time period. Coupled with cosmogenic (super 10) Be dating of intact, meter-scale outwash boulders preserved on terrace treads bounding each riser, detailed characterization of these geomorphic features provides a robust geologic slip-rate estimate for the Little Lake fault zone at the approximately 10 (super 4) year timescale. Preliminary correlation of terrace surfaces with available exposure dating of fluvially scoured basalt upstream at Fossil Falls suggests a right-lateral displacement-rate on the order of approximately 2 mm/yr. Although more than double the previously reported rate estimate ( or = approximately 5 mm/yr) on the Little Lake fault zone are not sustained geologically over longer periods of time.

There is evidence the Mg content in biogenic ACC is regulated by carboxylated (acidic) proteins and other macromolecules, but the physical basis for such a process is not well understood. In vitro experiments recently found that ACC compositions express a systematic relationship to the chemistry of carboxyl-rich biomolecules [1]. Molecules with a strong affinity for binding Ca compared to Mg promote the formation of Mg-enriched ACC products that are compositionally equivalent to high Mg-calcites and dolomite. Measurements show Mg/Ca ratios are controlled by a predictable dependence upon the binding properties of the organic molecules. The dependence suggests a physical basis for reports that specific sequences calcification promoting biomolecules are critical in modulating mineralization and controlling elemental signatures in carbonate skeletons. Insights from this study raise the long-standing question of why some geological carbonates often contain much higher Mg signatures than are possible by classical crystal growth processes in the laboratory. By analogy to calcification processes in organisms, we hypothesize that high Mg carbonates are formed by a non-classical process involving the transformation of these amorphous phases to the final crystalline product.

They are also characterized by the absence of interchondrule fine-grained matrix. The only fine-grained material is present as lithic clasts, which experienced extensive aqueous alteration in contrast to the surrounding high-temperature components (chondrules, refractory inclusions, metal grains). Hence, the clasts are foreign objects that were incorporated at a late stage into the final parent body of Isheyevo. Their origin is poorly constrained. Based on mineralogy, petrography, and thermal processing of the aromatic carbonaceous component, different types of clasts have been previously identified in the CB/CH-like chondrite Isheyevo. Here, we focus on the rare lithic clasts characterized by the presence of anhydrous silicates (chondrules, chondrule fragments, and CAIs). Their mineralogy and oxygen isotopic compositions reveal them to be micro-chondrules, fragments of chondrules, and refractory inclusions related to those in the Isheyevo host, suggesting accretion in the same region. In contrast to previously studied IDPs or primitive chondritic matrices, the fine-grained material in the clasts we studied is highly and rather uniformly enriched in heavy nitrogen, with bulk delta (super 15) N values ranging between 1000 ppm and 1300 ppm. It is also characterized by the presence of numerous (super 15) N hotspots (delta (super 15) N ranging from 1400 ppm to 4000 ppm). No bulk (delta D <--240 ppm) or localized deuterium enrichments were observed. These clasts have the highest bulk enrichment in heavy nitrogen measured to date in a fine-grained material. They represent a unique material, of asteroidal or cometary origin, in our collection of cosmomaterials. We show that they were (super 15) N-enriched before their incorporation in the final parent body of Isheyevo. They experienced an extensive aqueous alteration that most likely played a role in redistributing (super 15) N over the whole fine-grained material and may have significantly modified its initial hydrogen isotopic composition. Based on a review of isotopic fractionation models, we conclude that the nitrogen isotopic fractionation process, its timing, and its location are still poorly constrained. The (super 15) N-rich clasts may represent the surviving original carrier of the (super 15) N anomaly in Isheyevo whole-rock.

The new models were evaluated against the WRF model's standard Smagorinsky and 1.5-order turbulence kinetic energy (TKE) linear eddy-viscosity SFS stress models in simulations of geostrophically forced, neutral boundary layer flow over both flat terrain and a shallow, symmetric transverse ridge. Comparisons of simulation results with similarity profiles indicate that the nonlinear models significantly improve agreement with the expected profiles near the surface, reducing the overprediction of near-surface stress characteristic of linear eddy-viscosity models with no near-wall damping. Comparisons of simulations conducted using different mesh sizes indicate that the nonlinear model simulations at coarser resolutions agree more closely with the higher-resolution results than corresponding lower-resolution simulations using the standard WRF SFS stress models. The nonlinear models produced flows featuring a broader range of eddy sizes, with less spectral power at lower frequencies and more spectral power at higher frequencies. In simulated flow over the transverse ridge, distributions of flow separation and reversal near the surface simulated at higher resolution were likewise better depicted in coarser-resolution simulations using the nonlinear models.

Here we study crustal structure beneath the CVL and adjacent regions in Cameroon using 1-D shear wave velocity models obtained from the joint inversion of Rayleigh wave group velocities and P-receiver functions for 32 broad-band seismic stations deployed between 2005 January and 2007 February. We find that (1) crustal thickness (35-39 km) and velocity structure is similar beneath the CVL and the Pan African Oubanguides Belt to the south of the CVL, (2) crust is thicker (43-48 km) under the northern margin of the Congo Craton and is characterized by shear wave velocities > or =4.0 km s (super -1) in its lower part and (3) crust is thinner (26-31 km) under the Garoua rift and the coastal plain. In addition, a fast velocity layer (Vs of 3.6-3.8 km s (super -1) ) in the upper crust is found beneath many of the seismic stations. Crustal structure beneath the CVL and the Oubanguides Belt is very similar to Pan African crustal structure in the Mozambique Belt, and therefore it appears not to have been modified significantly by the magmatic activity associated with the CVL. The crust beneath the coastal plain was probably thinned during the opening of the southern Atlantic Ocean, while the crust beneath the Garoua rift was likely thinned during the formation of the Benue Trough in the early Cretaceous. We suggest that the thickened crust and the thick mafic lower crustal layer beneath the northern margin of the Congo Craton may be relict features from a continent-continent collision along this margin during the formation of Gondwana.

Lobes provide shorter-term records of internal and external processes that are potentially obliterated in the main body of long-lived, composite batholiths. Zircon ages complemented by thermal modeling indicate that lobe-sized magma chambers were present between approximately 0.2 and 1 m.y., representing only a small fraction of the total duration of melt presence in the main body. During these shorter intervals, a concentric pattern of normal compositional zoning formed during inward crystallization and widespread zircon recycling in the lobes. Lobes largely evolved as individual magma bodies that did not interact significantly with the main, more complex magma chamber(s). Antecrystic zircons and the range of autocrysts, used to track the extent of interconnected melt, record only a limited range of ages and have contrasting zircon populations to those found in the same units in the main batholith. We consider lobes to either be single batches formed during continuous magma flow or multiple, quickly coalescing pulses that in either case formed separate magma chambers that failed to amalgamate with other compositionally distinct pulses such as those occurring in the central batholith. Zircon age comparisons between all four lobes and the main body imply that growth of the Tuolumne intrusion was not stationary, but that the locus of magmatism shifted both inward and northwestward.

Published sequential dissolution studies have shown that carbonate dates in the 25-40 ka range increase by as much as 6 ka in 2-3 dissolution steps, but conclude that without an age plateau radiocarbon ages must be treated solely as minimum constraints. Mono Lake, California provides the most complete and sensitive record of late Pleistocene climate change of all the Great Basin lakes, because it neither dried nor spilled during the last glacial-interglacial cycle. Lacustrine sediments of the Wilson Creek Formation provide stratigraphic evidence for lake fluctuations and can be correlated around the basin with good confidence due to the occurrence of multiple ash layers. Extra-basinal correlation of millennial-scale changes in late Pleistocene Mono Lake level remains impossible, however, due to the contamination of carbonate radiocarbon dates with young carbon from atmospheric CO (sub 2) . Application of a modified sequential dissolution technique to radiocarbon dating of those carbonates shows that bulk radiocarbon ages on ostracodes and thinolite crystals in the upper part of the Wilson Creek Formation are younger than the oldest dated material by 1,000 to 3,000 years, indicating 5-14% modern carbon contamination. Micro-cave calcite collected from near the base of the section yielded a U-series age of 49.6 + or - 0.2 ka, a minimum limit clearly demonstrating that the age of the base of the section is beyond the range of standard radiocarbon dating, despite apparently finite bulk radiocarbon ages on ostracodes from that interval. Apparently finite radiocarbon ages ranging from 34,450 + or - 130 to 40,210 + or - 140 (super 14) C yr BP have also been measured on gastropods from shoreline tufas in the overflow to the Owens Basin, despite evidence that Mono Lake has not spilled in at least the last glacial cycle. Here we apply sequential dissolution to the micro-cave calcite and the overflow gastropods to confirm that deposition of the Wilson Creek Formation began >50 ka, and that the basin was hydrologically isolated during all of that time.

These ages correlate with other dates from the Alaska Range and other regions in Alaska and suggest synchronicity across Beringia during pulses of late Pleistocene glaciation. The ages do not support the previous correlation of the Delta glaciations with MIS 6. Several sample types were collected: boulders, single clasts, and gravel samples (amalgamated small clasts) from around boulders as well as from surfaces devoid of boulders. Comparing (super 10) Be ages of these sample types reveals the influence of pre/post-depositional processes, including boulder erosion, boulder exhumation, and moraine surface lowering. These processes occur continuously but seem to accelerate during and immediately after successive glacial episodes. The result is a multi-peak age distribution indicating that once a moraine persists through subsequent glaciations the chronological significance of cosmogenic ages derived from samples collected on that moraine diminishes significantly. The absence of Holocene ages implies relatively minor exhumation and/or weathering since 12 ka.

Typically, when building a conceptual model for groundwater flow and solute transport in subsurface system, we assume that the aquifer heterogeneous structures are fixed and just perform uncertainty analysis on hydraulic parameters. In this study an uncertainty quantification method is presented for a coupled modeling of aquifer heterogeneous structures and pumping test data (or tracer test data) utilizing a response surface-based optimization technique. Borehole geological descriptions and geophysical log data are used to characterize the aquifer facies transition probability models. Structure inversion here is performed by estimating the aquifer-structure parameters of a transition probability model and updating the aquifer multi-scale facies distributions with the indicator cokriging simulator. The stochastic property of the structure parameters are demonstrated with the plots of response surfaces, which are used for determining the optimal structure parameters. The Bayesian inference theory is used to quantify the uncertainty of the identified aquifer structures. This methodology is illustrated by two synthetic data sets: a set of pumping test data and a set of tracer test data.

We consider how to actively manage that migration so that it is beneficial. We analyze the concept of Active CO (sub 2) Reservoir Management, which is engineered CO (sub 2) and brine migration via injection/extraction/reinjection strategies, and contrast it with the conventional CCS approach, which can be called Passive CO (sub 2) Reservoir Management. Combining brine extraction with CO (sub 2) injection causes "push-pull" manipulation of the CO (sub 2) plume, which can enable exposing less of the caprock seal to CO (sub 2) and more of the storage aquifer to CO (sub 2) , with a greater fraction of the aquifer utilized for trapping mechanisms. Because CO (sub 2) storage capacity is greatly increased and brine migration is minimized, the area required for securing mineral rights is reduced per unit of stored CO (sub 2) . If an extraction ratio of one is used, which is defined as the net extracted volume of brine divided by the injected CO (sub 2) volume, pressure buildup is minimized, which greatly reduces the Area of Review, as well as the risk of induced seismicity. Because the migration of CO (sub 2) and brine will be unaffected by neighboring CO (sub 2) operations, planning, assessing, and conducting each CO (sub 2) operation within a basin can be carried out independently. In addition, the extracted brine is available as a feedstock for desalination technologies, such as Reverse Osmosis (RO). Depending on the extraction ratio, Enhanced Water Recovery may also be possible. All of these benefits will be useful during the regulatory approval process and for gaining public acceptance.

Over one hundred basin-scale erosion rates have been estimated cosmogenically in this region (Reuter, 2005; Duxbury, 2008; Trodick, this meeting); however, only 17 outcrop erosion rates have been measured until now. Outcrop erosion rates in the Potomac River basin (n=46) range from 1.0 + or - 0.11 to 66 + or - 4.8 m/My, average 15 + or - 1 m/My, and have a median of 7.1 + or - 0.6 m/My; outcrop erosion rates in the Susquehanna River basin (n=26) range from 1.8 + or - 0.2 to 28 + or - 2 m/My, average 10 + or - 0.7 m/My, and have a median of 8.3 + or - 0.7 m/My. The average bedrock outcrop erosion rate for the region is 13 + or - 1 m/My which is greater than the few other erosion rates measured on bedrock outcrops in the region (4-7 m/My, Reuter, 2005, Hancock and Kirwin, 2007; Duxbury, 2008). Outcrop erosion rates are significantly indistinguishable from the average basin rate of 12 m/My for 62 Potomac River sites (Trodick, this meeting) and significantly lower than the average basin rate of 20 m/My for 79 Susquehanna River sites (Reuter, 2005). Similar rates of erosion for bedrock outcrops and drainage basins suggest that the Central Appalachians as a whole have reached a general state of equilibrium. This is in contrast to some studies which suggest an increase in relief near our study sites (Reuter, 2005; Hancock and Kirwin, 2007). We observe a weak, positive correlation between bedrock outcrop erosion rates and relief in meters within a 5km radius (R (super 2) =0.24; p<0.0001), and an even weaker positive correlation between bedrock outcrop erosion rates and elevation (R (super 2) =0.11; p=0.0042). A weak, negative correlation is observed between bedrock outcrop erosion rates and latitude (R (super 2) =0.14; p=0.0013). Bedrock outcrop erosion rates were analyzed against mean annual precipitation and temperature but no correlations were significant.

In situ, basin-scale, (super 10) Be erosion rates range from 3 to 39 m/my with a mean and median of 12 m/my. Basins in the Coastal Plain (n=8) have the lowest erosion rates, 4 to 39 m/my with a mean of 10 m/my and a median of 6 m/my. The highest erosion rates are in Appalachian Plateau and Blue Ridge basins (n=6, n=8), each with a range from 9 to 18 m/my and a mean and median of 13 m/my. 21 samples from the Piedmont have erosion rates that range from 3 to 21 m/my, a mean of 12 m/my and a median of 13 m/my. 17 samples from the Valley and Ridge have a range from 4 to 30 m/my, a mean of 11 m/my and median of 9 m/my. These erosion rates are similar to basin-scale erosion rates measured in and near the Appalachian Mountains (4-54 m/my). We interpret measured meteoric (super 10) Be concentrations as erosion rates assuming steady state and a (super 10) Be delivery rate of 1.75 * 10 (super 6) atoms/(cm (super 2) *yr). Calculated erosion rates range from 4 m/my to 186 m/my with a mean of 36 m/my (3x mean in situ rate) and a median of 21 m/my (less than 2x the median of the in situ rate). The higher erosion rates calculated from meteoric (super 10) Be measurements most likely reflect violation of the steady state assumption caused by soil stripping from colonial and post colonial agriculture and subsequent landuse changes. The difference between in situ and meteoric-based erosion rate estimates could also reflect more rapid erosion of non-quartz bearing rocks than quartz bearing rocks. USGS sediment load data (n=10) suggest that rates of sediment export are similar, but slightly higher, than rates of sediment generation (12 m/my) in the Potomac Basin. The up stream sediment loads, when converted to lowering rates, range from 5 to 26 m/my with a mean of 17 m/my and a median of 16 m/my (n=9). A site at the mouth of the Potomac has a sediment load equivalent to 24 m/my lowering, similar to rates of sediment generation estimated by meteoric (super 10) Be (25 m/my) and in situ (super 10) Be (19 m/my) for sand samples collected at the site.

Owing to the generally erosive nature of ice sheets, however, few archives contain evidence of glacial erosion patterns during earlier glaciations. We compile both new and previously-published TCN and geochemical data to decipher spatial patterns of basal thermal regimes across Baffin Island on million-year time scales and present a conceptual model of fiord and landscape evolution. Ice from the Foxe Dome of the Laurentide Ice Sheet (LIS) flowed across Baffin Island, through deep fiords in the Arctic Rim, terminating in calving margins along Baffin Bay. While highly erosive ice carved fiords and cold-based ice covered intervening highlands during the last glaciation, the broad interior plateaux were covered by a patchwork of cold- and warm-based ice. TCN concentrations in bedrock and till inland of major fiords, as well as in clasts in basal ice of the last remnant of the LIS, require >3 m of bedrock erosion during the last glaciation alone. Conversely, TCN concentrations in bedrock and till from fiord rims, interfluves between fiord onset zones, and upland surfaces suggest minimal or no erosion over the past ca. 1.5 Myr. This interpretation is supported by geomorphic features and till geochemical weathering indices. We suggest that the evolution of basal thermal regime patterns over million-year time scales was controlled by the early Quaternary development of major fiord systems that provided highly efficient conduits for ice discharge. This focusing of flow reduced the ice flux into adjacent fiords, resulting in an increase in the area of cold-based ice present farther inland. We also suggest that some small, cold-based ice caps mantled the plateau highlands during the earliest stages of ice-sheet inception, and that this ice remained frozen to the bed for most or all of the subsequent glaciation.

Proteogenomic and biochemical studies of pellicle biofilms from subsurface acid mine drainage streams have shown abundant cytochromes from the dominant organism, Leptospirillum Group II. These cytochromes are proposed to be key proteins in aerobic Fe(II) oxidation, the dominant mode of cellular energy generation by the biofilms. In this study, we determined that posttranslational modification and expression of amino-acid sequence variants change as a function of biofilm maturation. For Cytochrome sub(579) (Cyt sub(579)), the most abundant cytochrome in the biofilms, late developmental-stage biofilms differed from early-stage biofilms in N-terminal truncations and decreased redox potentials. Expression of sequence variants of two monoheme c-type cytochromes also depended on biofilm development. For Cyt sub(572), an abundant membrane-bound cytochrome, the expression of multiple sequence variants was observed in both early and late developmental-stage biofilms; however, redox potentials of Cyt sub(572) from these different sources did not vary significantly. These cytochrome analyses show a complex response of the Leptospirillum Group II electron transport chain to growth within a microbial community and illustrate the power of multiple proteomics techniques to define biochemistry in natural systems.

Previous field studies suggested a complicated tectonic framework, including the possibility of Precambrian basement. Mattinson demonstrated the presence of Precambrian zircons (Yellow Aster Complex) and lower Paleozoic (Turtleback Complex), Triassic (Dumbell-Marblemount), Jurassic-Cretaceous (Chelan Complex) and Cretaceous plutons. Almost forty years later, we continue to unravel this complex history with an integrated field-based approach and the application of Mattinson's chemical-abrasion technique. The Northern Cascade Mountains represent the southernmost part of the Coast plutonic complex that extends for >1500 km from Alaska to Washington, interpreted to be related to a Mid-Cretaceous continental arc. The North Cascades is divided into the Wenatchee and Chelan Blocks by the post-metamorphic, high-angle Entiat Fault. The two blocks preserve different magmatic and metamorphic histories; the Wenatchee Block records arc magmatism from ca. 96 to 88 Ma while the Chelan Block records magmatism as young as ca. 45 Ma and was affected by Eocene orogen-parallel stretching and exhumation. Contractional deformation accompanied by intrusion of granitoid plutons thickened the crust to >55 km by ca. 90 Ma. Arc magmatism from ca 90-70 Ma is characterized by sheeted plutonic complexes intruded over 1-3 Ma. In the Eocene, the orogen is marked by metamorphism, magmatism, and mid-Eocene exhumation of the deep crust (Swakane Gneiss and the Skagit Gneiss Complex (SGC)), coincident with subsidence and rapid deposition in nearby non-marine basins. Swakane paragneiss protoliths were deposited ca. 71 Ma, intruded by 68 Ma pegmatites and exhumed from 11-12 kilobars. The SGC comprises 76-45 Ma tonalitic orthogneiss with metamorphism, melt generation and crystallization occurring from approximately 71-47 Ma terminating with nearly isothermal decompression from 10 to <5 kilobars. South of the core, sediments were deposited in the ca. 51 Ma Swauk Basin, folded, and intruded by 47 Ma Teanaway basalt dikes. We have documented the temporal coincidence between: basin formation, rapid deposition, partial melting, ductile flow, and upright folding of the SGC and Swauk Formation.

If experimentally-determined K d values do not represent sorption equilibria, errors are introduced in contaminant transport models. These errors may be further propagated when K d values are used to compare contaminant mobility under different chemical solution conditions. Our theoretical analysis based on pseudo-first order sorption kinetics shows that, independent if two systems have the same or different sorption kinetics, relative comparisons of K d values and retardation factors are always affected by sorption times under non-equilibrium conditions. The time-frames required for attaining constant K d values are not only dependent on kinetic sorption characteristics, but also the equilibrium K d values approached. The type of kinetic errors introduced is affected by the specific differences in sorption kinetics and equilibrium K d values between the two systems. For systems with the same sorption kinetics, relative increases or decreases in contaminant velocities are always underestimated. In case of different kinetics, either an under- or overestimation of relative differences seems possible. Experimental sorption times should aim to equilibrate the system with the highest K d value for systems with comparable kinetics, and the system with the slowest sorption kinetics for different kinetics.

Our methodology includes full elastic anisotropy, time and temperature varying material properties, and multilayer capabilities. In order to achieve fast fluences up to 30 x 10 super(25) n m super(-2) (E > 0.18 MeV), judicious extrapolations across several orders of magnitude of existing material databases have been carried out. The results of our study indicate that failure of the pyrolytic carbon (PyC) layers occurs within the first 2 years of operation. The particles then behave as a single-SiC-layer particle and the SiC layer maintains reasonably-low tensile stresses until the end-of-life. It is also found that the PyC creep constant, K, has a striking influence on the fuel performance of TRISO-coated particles, whose stresses scale almost inversely proportional to K. Conversely, varying the geometry of the TRISO-coated fuel particles results in little differences in terms of fuel performance.

The parameters were as follows: (i) type of Bacillus spore surrogate (B. thuringiensis or B. atrophaeus), (ii) spore concentration in suspension (102 and 106 spores/ml), (iii) chemical characteristics of the decontaminant (sodium dichloro-S-triazinetrione dihydrate [Dichlor], hydrogen peroxide, potassium peroxymonosulfate [Oxone], sodium hypochlorite, and VirkonS), (iv) decontaminant concentration (0.01% to 5%), and (v) exposure time to decontaminant (10 min to 1 h). Results from 138 suspension tests with appropriate controls are reported. Hydrogen peroxide at a concentration of 5% and Dichlor or sodium hypochlorite at a concentration of 2% were highly effective at spore inactivation regardless of spore type tested, spore exposure time, or spore concentration evaluated. This is the first reported study of Dichlor as an effective decontaminant for B. anthracis spore surrogates. Dichlor's desirable characteristics of high oxidation potential, high level of free chlorine, and a more neutral pH than that of other oxidizers evaluated appear to make it an excellent alternative. All three oxidizers were effective against B. atrophaeus spores in meeting the EPA biocide standard of greater than a 6-log kill after a 10-min exposure time and at lower concentrations than typically reported for biocide use. Solutions of 5% VirkonS and Oxone were less effective as decontaminants than other options evaluated in this study and did not meet the EPA's efficacy standard for a biocide, although they were found to be as effective for concentrations of 102 spores/ml. Differences in methods and procedures reported by other investigators make quantitative comparisons among studies difficult.

A common preventative treatment for PE is the insertion of a metallic filter into the inferior vena cava that traps thrombi before they reach the lungs. The goal of this work is to use methods of mathematical modeling and design optimization to determine the configuration of trapped thrombi that minimizes the hemodynamic disruption. The resulting configuration has implications for constructing an optimally designed vena cava filter. Computational fluid dynamics is coupled with a nonlinear optimization algorithm to determine the optimal configuration of a trapped model thrombus in the inferior vena cava. The location and shape of the thrombus are parametrized, and an objective function, based on wall shear stresses, determines the worthiness of a given configuration. The methods are fully automated and demonstrate the capabilities of a design optimization framework that is broadly applicable. Changes to thrombus location and shape alter the velocity contours and wall shear stress profiles significantly. For vena cava filters that trap two thrombi simultaneously, the undesirable flow dynamics past one thrombus can be mitigated by leveraging the flow past the other thrombus. Streamlining the shape of the thrombus trapped along the cava wall reduces the disruption to the flow but increases the area exposed to low wall shear stress. Computer-based design optimization is a useful tool for developing vena cava filters. Characterizing and parametrizing the design requirements and constraints is essential for constructing devices that address clinical complications. In addition, formulating a well-defined objective function that quantifies clinical risks and benefits is needed for designing devices that are clinically viable.

ER - TY - JOUR T1 - California Wintertime Precipitation Bias in Regional and Global Climate Models AN - 807281319; 13839210 AB - In this paper, wintertime precipitation from a variety of observational datasets, regional climate models (RCMs), and general circulation models (GCMs) is averaged over the state of California and compared. Several averaging methodologies are considered and all are found to give similar values when the model grid spacing is less than 3. This suggests that California is a reasonable size for regional intercomparisons using modern GCMs. Results show that reanalysis-forced RCMs tend to significantly overpredict California precipitation. This appears to be due mainly to the overprediction of extreme events; RCM precipitation frequency is generally underpredicted. Overprediction is also reflected in wintertime precipitation variability, which tends to be too high for RCMs on both daily and interannual scales. Wintertime precipitation in most (but not all) GCMs is underestimated. This is in contrast to previous studies based on global blended gauge-satellite observations, which are shown here to underestimate precipitation relative to higher-resolution gauge-only datasets. Several GCMs provide reasonable daily precipitation distributions, a trait that does not seem to be tied to model resolution. The GCM daily and interannual variabilities are generally underpredicted.

In this paper, we introduce a new way of assessing confidence in the regional full moment-tensor inversion via the introduction of the network sensitivity solution (NSS). The NSS takes into account the unique station distribution, frequency band, and signal-to-noise ratio of a given event scenario. The NSS compares both a hypothetical pure source (for example, an explosion or an earthquake) and the actual data with several thousand sets of synthetic data from a uniform distribution of all possible sources. The comparison with a hypothetical pure source provides the theoretically best-constrained source-type distribution for a given set of stations; and with it, one can determine whether further analysis with the data is warranted. The NSS that employs the actual data gives a direct comparison of all other source types with the best-fit source. In this way, one can choose a threshold level of fit in which the solution is comfortably constrained. The method is tested for the well-recorded nuclear test, JUNCTION, at the Nevada Test Site. Sources that fit comparably well to a hypothetical pure explosion recorded with no noise at the JUNCTION data stations have a large volumetric component and are not described well by a double-couple (DC) source. The NSS using the real data from JUNCTION is even more tightly constrained to an explosion because the data contain some energy that precludes fitting with any type of deviatoric source. We also calculate the NSS for the October 2006 North Korea test and a nearby earthquake, where the station coverage is poor and the event magnitude is small. The earthquake solution is very well fit by a DC source, and the best-fit solution to the nuclear test (M (sub w) 4.1) is dominantly explosion.

The first method solves for source, site, and path attenuation. The second method uses a scaling relationship to set the initial source amplitude and interpret the source term after inversion. The third method implements a coda-derived source spectral correction. By comparing methods with slightly different assumptions we are able to make a more realistic assessment of the uncertainties in the resulting attenuation maps than is obtainable through formal error analysis alone. We compare the site, source and path-terms produced by each method and comment on attenuation, which correlates well with tectonic and topographic features in the region. Source terms correlate well with each other and with magnitude. Site terms are similar except for two stations that are located in a region that has the greatest difference in path term, which demonstrates the site/path trade-off. Another region of path term difference has the fewest crossing paths, where the tomography method employing the coda-derived spectral correction may perform more accurately since it is not as susceptible to the source/path trade-off. The Bohai Bay basin, an area of extension, is a region of high attenuation, and regions of low attenuation occur along topographic highs located in the Da-xin-an-ling and Changbai Mountains and Mount Taishan.

AN - 753999930; 20669912 AB - Understanding the role of surface chemistry in the stability of nanostructured noble-metal materials is important for many technological applications but experimentally difficult to access and thus little understood. To develop a fundamental understanding of the effect of surface chemistry on both the formation and stabilization of self-organized gold nanostructures, we performed a series of controlled-environment annealing experiments on nanoporous gold (np-Au) and ion-bombarded Au(111) single-crystal surfaces. The annealing experiments on np-Au in ambient ozone were carried out to study the effect of adsorbed oxygen under dynamic conditions, whereas the ion-bombarded Au single-crystal surfaces were used as a model system to obtain atomic-scale information. Our results show that adsorbed oxygen stabilizes nanoscale gold structures at low temperatures whereas oxygen-induced mobilization of Au surface atoms seems to accelerate the coarsening under dynamic equilibrium conditions at higher temperatures.

The baseline design uses a depleted uranium (DU) fission fuel blanket with a flowing molten salt coolant (flibe) that also breeds the tritium needed to sustain the fusion energy source. Indirect drive targets, similar to those that will be demonstrated on the National Ignition Facility (NIF), are ignited at [inline image]13 Hz providing a 500 MW fusion source. The du is in the form of a uranium oxycarbide kernel in modified TRISO-like fuel particles distributed in a carbon matrix forming 2-cm-diameter pebbles. The thermal power is held at 2000 MW by continuously varying the [super]6Li enrichment in the coolants. There are many options to be considered in the engine design including target yield, U-to-C ratio in the fuel, fission blanket thickness, etc. Here we report results of design variations and compare them in terms of various figures of merit such as time to reach a desired burnup, full-power years of operation, time and maximum burnup at power ramp-down and the overall balance of plant utilization.

Progressing downward from the soil zone overlying the cave, these processes include soil respiration, fluid-rock interaction in the host limestone, degassing of CO (sub 2) and precipitation of calcite upflow from the speleothem drip site, and calcite precipitation at the drip site. Here we develop a new approach to independently constrain the roles of water-rock interaction and soil processes in controlling stalagmite delta (super 13) C. This approach uses the dead carbon proportion (dcp) estimated from coupled (super 14) C and (super 230) Th/U measurements, in conjunction with Sr isotope analyses on stalagmite calcite from a central Sierra Nevada foothills cave in California, a region characterized by a highly seasonal Mediterranean-type climate, to determine the roles of water-rock interaction and soil processes in determining stalagmite delta (super 13) C. Increases in stalagmite dcp between 16.5 and 8.8 ka are coincident with decreased delta (super 13) C, indicating a varying yet substantial contribution from the soil organic matter (SOM) reservoir, likely due to significantly increased average age of SOM in the soil veneer above the cave during wet climatic intervals. We use geochemical and isotope mixing models to estimate the host-carbonate contribution throughout the delta (super 13) C time series and determine the degree of degassing and calcite precipitation that occurred prior to precipitation of stalagmite calcite. The degree of degassing and prior calcite precipitation we calculate varies systematically with other climate indicators, with less degassing and prior calcite precipitation occurring during wetter climatic intervals and more during drier intervals. Modeled delta (super 13) C values and degassing calculations suggest that some degree of prior calcite precipitation is necessary at all time intervals to explain measured stalagmite delta (super 13) C values, even during relatively wet intervals. These results illustrate the importance of constraining degassing and prior calcite precipitation in the interpretation of speleothem delta (super 13) C records, particularly those from caves that formed in seasonal semi-arid to arid environments.

To describe this effect, we use the term 'superresolution', a term widely used in the optics and signal processing literature to denote systems that break the diffraction limit. We illustrate superresolution with Pn signals recorded by the ARCES array in northern Norway, using them to identify the origins with 98.2 per cent accuracy of 549 explosions conducted by closely spaced mines in northwest Russia. The mines are observed at 340-410 km range and are separated by as little as 3 km. When viewed from ARCES many are separated by just tenths of a degree in azimuth. This classification performance results from an adaptation to transient seismic signals of techniques developed in underwater acoustics for localization of continuous sound sources. Matched field processing is a potential competitor to frequency-wavenumber (FK) and waveform correlation methods currently used for event detection, classification and location. It operates by capturing the spatial structure of wavefields incident from a particular source in a series of narrow frequency bands. In the rich seismic scattering environment, closely spaced sources far from the observing array nonetheless produce distinct wavefield amplitude and phase patterns across the small array aperture. With observations of repeating events, these patterns can be calibrated over a wide band of frequencies (e.g. 2.5-12.5 Hz) for use in a power estimation technique similar to frequency-wavenumber analysis. The calibrations enable coherent processing at high frequencies at which wavefields normally are considered incoherent under a plane-wave model. Abstract Copyright (2010), RAS.

We provide new estimates of the amount of fault offset of the T2 fan based on trench excavations and new cosmogenic (super 10) Be age determinations from the tops of 12 boulders on the fan surface. We present three alternative fan offset models: a minimum, a maximum, and a preferred offset of 660 m, 980 m, and 770 m, respectively. We assign an age of between 45 and 54 ka to the T2 fan from the (super 10) Be data, which is significantly older than previously reported but is consistent with both the degree of soil development associated with this surface, and with ages from U-series geochronology on pedogenic carbonate from T2, described in a companion paper by Fletcher et al. (this volume). These new constraints suggest a range of slip rates between approximately 12 and 22 mm/yr with a preferred estimate of approximately 14-17 mm/yr for the Mission Creek strand of the southern San Andreas fault. Previous studies suggested that the geologic and geodetic slip-rate estimates at Biskra Palms differed. We find, however, that considerable uncertainty affects both the geologic and geodetic slip-rate estimates, such that if a real discrepancy between these rates exists for the southern San Andreas fault at Biskra Palms, it cannot be demonstrated with available data.

We now describe a new experimental calibration program firing very small monodisperse silica projectiles (470 nm-10 mu m) at approximately 6 km s (super -1) . The results show an unexpected departure from linear relationship between 1 and 10 mu m. We collated crater measurement data and, where applicable, impactor residue data for 596 craters gathered during the postmission preliminary examination phase. Using the new calibration, we recalculate the size of the particle responsible for each crater and hence reinterpret the cometary dust size distribution. We find a greater flux of small particles than previously reported. From crater morphology and residue composition of a subset of craters, the internal structure and dimensions of the fine dust particles are inferred and a "maximum-size" distribution for the subgrains composing aggregate particles is obtained. The size distribution of the small particles derived directly from the measured craters peaks at approximately 175 nm, but if this is corrected to allow for aggregate grains, the peak in subgrain sizes is at <100 nm.

About 3600 wave trains with S and Love waves and 5700 Love-wave group velocity dispersion curves are jointly inverted for SH-velocity perturbations from a pre-existing, 3-D SV-velocity model. These perturbations are predominantly positive (SH faster than SV) and consistent with PREM, but our model also shows significant lateral variation in radial anisotropy that appears to be correlated with tectonic environment. SH waves travel faster than SV wave beneath backarc basins, oceans and orogenic belts such as the Tyrrhenian and Pannonian basins, the Ionian Sea, the Alps, the Apennines, the Dinarides and the Caucasus. The Algero-Provencal basin, however, is underlain by faster SV velocity. Faster SV velocity of radial anisotropy is also detected within cratons such as the East European platform and the Arabian shield. Beneath hotspots we detect a change in radial anisotropic polarity with depth, which may be caused by transition between the lattice-preferred orientation from horizontal deformation in the asthenosphere and the shape-preferred orientation from vertically oriented melt channels in the lithosphere. We also find significant portion of radial anisotropy within subducting slabs depends on the slab's dip angle. Abstract Copyright (2010), RAS.

Conceptually, this method uses an earthquake source model along with an attenuation model and geometrical spreading that accounts for the propagation to utilize regional phase amplitudes of any phase and frequency. Amplitudes are corrected to yield a source term from which one can estimate the seismic moment. Moment magnitudes can then be reliably determined with sets of observed phase amplitudes rather than predetermined ones and afterward averaged to robustly determine this parameter. We first examine in detail two events to demonstrate the methodology. We then look at various ensembles of phases and frequencies and compare results to existing regional methods. We find regional M (sub 0) to be a stable estimator of earthquake size that has several advantages over other methods. Because of its versatility, it is applicable to many more events, particularly smaller events. We make moment estimates for earthquakes ranging from magnitude 2 to as large as 7. Even with diverse input amplitude sources, we find magnitude estimates with this method to be more robust than typical magnitudes and existing regional methods, and the magnitude estimates might be tuned further to improve upon them. The method yields a more meaningful quantity of seismic moment, which can be recast as M (sub w) . Lastly, it is applied here to the Middle East region using an existing calibration model, but it would be easy to transport to any region with suitable attenuation calibration.

The sediment records from deep water consist mainly of alternating clay, gypsum and carbonate units and, in at least two drill sites, extend back >200 kyr. Most of the lithostratigraphic units are traceable throughout the basin along seismic reflections that serve as seismic stratigraphic boundaries and suggest that the lithostratigraphy can be used to infer regional palaeoenvironmental changes. A revised seismic stratigraphy was established on the basis of integrated lithological and seismic reflection data from the basin. From ca 200 to ca 85 ka, sediments are dominated by carbonate-clay silt, often interbedded with sandy turbidites, indicating a sediment regime dominated by detrital sedimentation in a relatively humid climate. At ca 85 ka, an exposure horizon consisting of gravels, coarse sand and terrestrial gastropods marks a lake lowstand or partial basin desiccation, indicating dry climate conditions. From ca 85 to ca 48 ka, transgressive carbonate-clay sediments, overlain by deep-water clays, suggest a lake level rise and subsequent stabilization at high stage. From ca 48 ka to present, the lithology is characterized by alternating clay and gypsum units. Gypsum deposition correlates with Heinrich Events (i.e. dry climate), whereas clay units coincide with more humid interstadials.

Sacramento-San Joaquin River basin, California AN - 886909854; 2011-074612 AB - We used radiocarbon measurements of dissolved organic carbon (DOC) to resolve sources of riverine carbon within agriculturally dominated landscapes in California. During 2003 and 2004, average Delta (super 14) C for DOC was -254 ppm in agricultural drains in the Sacramento-San Joaquin Delta, -218 ppm in the San Joaquin River, -175 ppm in the California State Water Project and -152 ppm in the Sacramento River. The age of bulk DOC transiting the rivers of California's Central Valley is the oldest reported for large rivers and suggests wide-spread loss of soil organic matter caused by agriculture and urbanization. Using DAX 8 adsorbent, we isolated and measured (super 14) C concentrations in hydrophobic acid fractions (HPOA); river samples showed evidence of bomb-pulse carbon with average Delta (super 14) C of 91 and 76 ppm for the San Joaquin and Sacramento Rivers, respectively, with older HPOA, -204 ppm, observed in agricultural drains. An operationally defined non-HPOA fraction of DOC was observed in the San Joaquin River with seasonally computed Delta (super 14) C values of between -275 and -687 ppm; the source of this aged material was hypothesized to be physically protected organic-matter in high clay-content soils and agrochemicals (i.e., radiocarbon-dead material) applied to farmlands. Mixing models suggest that the Sacramento River contributes about 50% of the DOC load in the California State Water Project, and agricultural drains contribute approximately one-third of the load. In contrast to studies showing stabilization of soil carbon pools within one or two decades following land conversion, sustained loss of soil organic matter, occurring many decades after the initial agricultural-land conversion, was observed in California's Central Valley.

We present a tomography-based model of mantle convection that provides an excellent match to fundamental surface geodynamic constraints on internal density heterogeneity that includes both compositional and thermal contributions, where the latter are constrained by mineral physics. The application of this thermochemical convection model to the problem of African mantle dynamics yields a reconciliation of both surface gravity and topography anomalies to deep-seated mantle flow under the African plate, over a wider range of wavelengths than has been possible to date. On the basis of these results, we predict flow in the African asthenosphere characterised by a clear pattern of focussed upwellings below the major centres of late Cenozoic volcanism, including the Kenya domes, Hoggar massif, Cameroon volcanicline, Cape Verde and Canary Islands. The flow predictions also reveal a deep-seated, large-scale, active hot upwelling below the western margin of Africa under the Cape Verde Islands that extends down to the core-mantle boundary. The scale and dynamical intensity of this 'West African Superplume' is comparable to the 'South African Superplume' that has long been assumed to dominate the large-scale flow dynamics in the deep-mantle under Africa. We evaluate the plausibility of the predicted asthenospheric flow patterns through a comparison with seismic azimuthal anisotropy derived from independent analyses of African shear wave splitting data.

The analyzed clasts belong to the "albitic lithology," the most abundant population of indigenous feldspathic materials in polymict ureilites, and are highly fractionated igneous assemblages of albitic plagioclase, Fe-rich pyroxenes, phosphates, ilmenite, silica, and Fe(Mn, K, P, Ti)-enriched glass. Glass in DaG 165 clast 19 has extremely high and variable (super 55) Mn/ (super 52) Cr ratios (500-58,000) and shows correlated (super 53) Cr excesses up to approximately 1500 ppm, clearly indicating the presence of live (super 53) Mn at the time of formation. The slope of the well-correlated isochron defined by glass and pyroxenes from this clast corresponds to ( (super 53) Mn/ (super 55) Mn)=(2.84+ or -0.10)X10 (super -6) (2sigma ). Data for less (super 55) Mn/ (super 52) Cr-enriched glasses from DaG 319 clast B1, as well as phosphates from several other clasts, are consistent with this isochron. The (super 53) Mn/ (super 55) Mn ratio obtained from the isochron implies that these clasts are 0.70+ or -0.18 Ma younger than the D'Orbigny angrite, corresponding to the absolute age of 4563.72+ or -0.22 Ma. Plagioclase in DaG 319 clast B1 has a fairly constant (super 27) Al/ (super 24) Mg ratio of approximately 900 and shows resolvable (super 26) Mg excesses of approximately 2 ppm. The slope of the isochron defined by pyroxene and plagioclase in this clast is (3.0+ or -1.1)X10 (super -7) (2sigma ), corresponding to a time difference of 5.4 (-0.3/+0.5) Ma after CAI (assuming the canonical initial (super 26) Al/ (super 27) Al ratio of 5X10 (super -5) ) and an age 0.5 (-0.3/+0.5) Ma younger than D'Orbigny. Its absolute age (relative to D'Orbigny) is 4563.9 (+0.4/-0.5) Ma, in agreement with the (super 53) Mn- (super 53) Cr age from clast 19. These data provide the first high-precision age date, approximately 5.4 Ma after CAI, for ureilites, giving a minimum estimate for the age of differentiation of their parent asteroid. Interpretation of this age for the thermal and physical history of that asteroid depends on a number of currently unknown or model-dependent parameters, including its size, bulk composition, and oxidation state, and the petrologic relationship between the feldspathic clasts and main group ureilites.

The modeling involves two-phase (liquid and gas) and two-component (water and air) transport in a fractured-rock system, which is conceptualized as a dual-permeability medium. Simulated hydrologic processes depend upon calibrated system parameters, such as the van Genuchten alpha and m, which quantify the capillary properties of the fractures and rock matrix. Typically, these parameters are not calibrated for strongly heat-driven conditions, i.e., conditions for which boiling and rock dryout occur. The objective of this study is to modify the relationship between capillary pressure and saturation, P (sub c) (S), for strongly heated conditions that drive saturation below the residual saturation (S-->0). We offer various extensions to the van Genuchten capillary-pressure function and compare results from a thermal-hydrologic model with data collected during the Drift-Scale Test, an in situ thermal test at Yucca Mountain, to investigate the suitability of these various P (sub c) extension methods. The study suggests that the use of extension methods and the imposition of a capillary-pressure cap (or maximum) improve the agreement between Drift-Scale Test data and model results for strongly heat-driven conditions. However, for thermal-hydrologic models of the Yucca Mountain nuclear waste repository, temperature and relative humidity are insensitive to the choice of extension method for the capillary-pressure function. Therefore, the choice of extension method applied to models of drift-scale thermal-hydrologic behavior at Yucca Mountain can be made on the basis of numerical performance.

A simulator package utilizing a model-to-satellite approach facilitates comparison of model simulations to observations, and a revised clustering method is used to sort the subgrid-scale patterns of clouds and precipitation into principal cloud regimes. Results from weather forecasts performed with CAM3 suggest that the model underestimates the horizontal extent of low-level and midlevel clouds in subsidence regions but overestimates that of high clouds in ascending regions. CAM3 strongly overestimates the frequency of occurrence of the deep convection with heavy precipitation regime but underestimates the horizontal extent of clouds and precipitation at low and middle levels when this regime occurs. This suggests that the model overestimates convective precipitation and underestimates stratiform precipitation consistent with a previous study that used only precipitation observations. Tropical cloud regimes are also evaluated in a different version of the model, CAM3.5, which uses a highly entraining plume in the parameterization of deep convection. While the frequency of occurrence of the deep convection with heavy precipitation regime from CAM3.5 forecasts decreases, the incidence of the low clouds with precipitation and congestus regimes increases. As a result, the parameterization change does not reduce the frequency of precipitating convection, which is far too high relative to observations. For both versions of CAM, clouds and precipitation are overly reflective at the frequency of the CloudSat radar and thin clouds that could be detected by the lidar only are underestimated.

Here, we present optical absorption data for lower mantle minerals to assess the effect of composition (including iron oxidation state), structure, and iron spin state on radiative heat transfer. We confirm that the presence of ferric iron in ferropericlase strongly affects the optical properties, while the effect of the spin-pairing transition may be more secondary. We also show that post-perovskite exhibits larger optical absorption in the near infrared and visible spectral ranges than perovskite which may have a profound effect on the dynamics the lowermost mantle. We present preliminary results from measurements of the phonon thermal conductivity of perovskite at 125 GPa using a pulsed laser heating technique. The available data suggest a larger value than what previously estimated, although the uncertainty is large.

Over the investigated pressure range the aggregate compressional sound velocity is approximately 9% higher than in pure iron at the same density. The measured aggregate compressional (V (sub P) ) and shear (V (sub S) ) sound velocities, extrapolated to core densities and corrected for anharmonic temperature effects, are compared with seismic profiles. Our results provide constraints on the silicon abundance in the core, suggesting a model that simultaneously matches the primary seismic observables, density, P-wave and S-wave velocities, for an inner core containing 4 to 5 wt.% of Ni and 1 to 2 wt. of Si.

ATP-dependent activity of a membrane ion pump, Na(+)/K(+)-ATPase, embedded in a lipid membrane covering the carbon nanotube, modulates the transistor output current by up to 40%. The ion pump gates the device by shifting the pH of the water layer between the lipid bilayer and nanotube surface. This transistor is a versatile bionanoelectronic platform that can incorporate other membrane proteins.

The ventilated volumes and ages in the upper wind driven layer are related to the wind stress curl and surface buoyancy fluxes at mid to high latitudes in the North Pacific. In contrast, the deeper thermohaline layers are more effectively ventilated by direct atmosphere-sea exchange during convective formation of Subantarctic Mode Waters (SAMW) and Antarctic Intermediate Waters (AAIW) in the Southern Ocean, the precursors of Pacific Intermediate Waters (PIW) in the North Pacific. Results reported here show a fundamental change in the carbon isotopic gradient between intermediate and deep waters during the LGM in the eastern North Pacific indicating a deepening of nutrient and carbon rich waters. These observations suggest changes in the source and nature of intermediate waters of Southern Ocean origin that feed PIW and enhanced ventilation processes in the North Pacific, further affecting paleoproductivity and export patters in this basin. Furthermore, oxygen isotopic results indicate these changes may have been accomplished in part by changes in circulation affecting the intermediate depths during the LGM.

Previous investigations of the KCF underscore its importance as a Late Cretaceous and Neogene shear zone in the tectonic development of the southern Sierra Nevada. Study of the late Quaternary history of activity, however, has been confounded by the remote nature of the KCF and deep along-strike exhumation within the northern Kern River drainage, driven by focused fluvial and glacial erosion. Recent acquisition of airborne LiDAR (light detection and ranging) topography along the approximately 140 km length of the KCF provides a comprehensive view of the active surface trace. High-resolution, LiDAR-derived digital elevation models (DEMs) for the northern KCF enable identification of previously unrecognized offsets of late Quaternary moraines near Soda Spring (36.345, -118.408). Predominately north-striking fault scarps developed on the Soda Spring moraines display west-side-up displacement and lack a significant sense of strike-slip separation, consistent with detailed mapping and trenching along the entire KCF. Scarp-normal topographic profiling derived from the LiDAR DEMs suggests normal displacement of at least 2.8 +0.6/-0.5 m of the Tioga terminal moraine crest. Cosmogenic (super 10) Be exposure dating of Tioga moraine boulders yields a tight age cluster centered around 18.1 + or - 0.5 ka (n = 6), indicating a minimum normal-sense fault slip-rate of approximately 0.1-0.2 mm/yr over this period. Taken together, these results provide clear documentation of late Quaternary activity on the KCF and highlight its role in accommodating extension and internal deformation of the southern Sierra Nevada Microplate.

At Mono Lake the final highstand is marked by the sequence of Ashes 1-2-3-4, readily-identifiable in deep lake sediments as high as 50-60 m above average late-Pleistocene levels. Carbonate (super 14) C dates and (super 40) Ar/ (super 39) Ar on rhyolitic ashes in the Wilson Creek Formation sediments both have complications, and for the high-precision and accuracy required to correlate global changes, improved chronological constraints are required. We have built on previous progressive leaching experiments to separate and radiocarbon date the oldest carbon in a sample, on the premise that all younger carbon is contamination added after the time of the original precipitation. After weighing carbonate into a sealed vial, the vial is evacuated, phosphoric acid is added, and the vial attached to the graphitization rig. Using variable concentrations of acid, sampling intervals, and amounts of heat, we have dated multiple steps on ostracodes, thinolite, and gastropods. The results show that surface area-to-volume ratio is the most important factor in separating multiple steps: thinolite crushed to >300 microns can be controlled easily, while ostracodes are quite thin and delicate, making the reaction much more difficult to control. Eleven steps on a thinolite fan from above Ash 1 show an increase of more than 2000 years from first to last step, and approximately 400 year increase over a lightly-leached bulk sample. A weighted mean of the final ages, 10,920 + or - 20 (super 14) C yrs BP, minus a 1000-year reservoir effect, calibrates to 11,300 + or - 70 cal yr BP, close to the end of the Younger Dryas interval recorded in Hulu cave (11,470 + or - 100 ka). Several sets of leaches on one ostracode sample yielded 4000- to 7000-year differences between first and last leach steps and 3500 years between the oldest leach and a bulk sample date. Calibration of the oldest leach age corresponds to 13,900 + or - 170 cal yr BP (with 1 ka reservoir correction). These results suggest that both the cold Younger Dryas and the warm Bolling-Allerod were extremely wet. Future work will increase the number of reliably-dated carbonates, and clarify the relation of the Mono Lake highstand to global climate changes.

These models were built from a previous methyl decanoate mechanism and were compared with rapeseed oil methyl esters oxidation experiments in a jet-stirred reactor. A comparative study of the reactivity of these three oxygenated compounds was performed and the differences in the distribution of the products of the reaction were highlighted showing the influence of the presence and the position of a double bond in the chain. Blend surrogates, containing methyl decanoate, methyl-5-decenoate, methyl-9-decenoate and n-alkanes, were tested against rapeseed oil methyl esters and methyl palmitate/n-decane experiments. These surrogate models are realistic kinetic tools allowing the study of the combustion of biodiesel fuels in diesel and homogeneous charge compression ignition engines.

The purpose of the study was to compare environmental swab processing methods for recovery, detection, and quantification of viable B. anthracis spores from surfaces. Results show that spore numbers provided by the MPN RV-PCR method were typically within 1-log of the values from a plate count method for all three levels of spores tested (3.1A-104, 400, and 40 spores sampled from surfaces with swabs) even in the presence of debris. The MPN method tended to overestimate the expected result, especially at lower spore levels. Blind negative samples were correctly identified using both methods showing a lack of cross contamination. In addition to detecting low levels of spores in environmental conditions, the MPN RV-PCR method is specific, and compatible with automated high-throughput sample processing and analysis protocols, enhancing its utility for characterization and clearance following a biothreat agent release.

Isotopic and elemental gradients in the B. thuringiensis subsp. israelensis spores show the permeation and incorporation of deuterium in deuterated water (D2O) and solvated ions throughout individual spores, including the spore core. Under hydrated conditions, incorporation into a spore occurs on a time scale of minutes, with subsequent uptake of the permeating species continuing over a period of days. The distribution of available adsorption sites is shown to vary with the permeating species. Adsorption sites for Li+, Cs+, and Cl- are more abundant within the spore outer structures (exosporium, coat, and cortex) relative to the core, while F- adsorption sites are more abundant in the core. The results presented here demonstrate that elemental abundance and distribution in dormant spores are influenced by the ambient environment. As such, this study highlights the importance of understanding how microbial elemental and isotopic signatures can be altered postproduction, including during sample preparation for analysis, and therefore, this study is immediately relevant to the use of elemental and isotopic markers in environmental microbiology and microbial forensics.

The EPS obtained from a mid-developmental-stage biofilm (DS1) and a mature biofilm (DS2) were qualitatively and quantitatively compared. More than twice as much EPS was derived from DS2 as from DS1 (approximately 340 and 150 mg of EPS per g [dry weight] for DS2 and DS1, respectively). Composition analyses indicated the presence of carbohydrates, metals, proteins, and minor quantities of DNA and lipids, although the relative concentrations of these components were different for the two EPS samples. EPS from DS2 contained higher concentrations of metals and carbohydrates than EPS from DS1. Fe was the most abundant metal in both samples, accounting for about 73% of the total metal content, followed by Al, Mg, and Zn. The relative concentration profile for these metals resembled that for the AMD solution in which the biofilms grew, except for Si, Mn, and Co. Glycosyl composition analysis indicated that both EPS samples were composed primarily of galactose, glucose, heptose, rhamnose, and mannose, while the relative amounts of individual sugars were substantially different in DS1 and DS2. Additionally, carbohydrate linkage analysis revealed multiply linked heptose, galactose, glucose, mannose, and rhamnose, with some of the glucose in a 4-linked form. These results indicate that the biochemical composition of the EPS from these acidic biofilms is dependent on maturity and is controlled by the microbial communities, as well as the local geochemical environment.

2013-044608 AB - We present a new analysis of the Jupiter+Saturn analog system, OGLE-2006-BLG-109Lb,c, which was the first double planet system discovered with the gravitational microlensing method. This is the only multi-planet system discovered by any method with measured masses for the star and both planets. In addition to the signatures of two planets, this event also exhibits a microlensing parallax signature and finite source effects that provide a direct measure of the masses of the star and planets, and the expected brightness of the host star is confirmed by Keck AO imaging, yielding masses of MM (sub *) =0.51 (super +0.05) (sub -0.04) M (sub sun) , M (sub b) =231+ or -19 M+, and M (sub c) =86+ or -7 M+. The Saturn-analog planet in this system had a planetary light-curve deviation that lasted for 11 days, and as a result, the effects of the orbital motion are visible in the microlensing light curve. We find that four of the six orbital parameters are tightly constrained and that a fifth parameter, the orbital acceleration, is weakly constrained. No orbital information is available for the Jupiter-analog planet, but its presence helps to constrain the orbital motion of the Saturn-analog planet. Assuming co-planar orbits, we find an orbital eccentricity of epsilon =0.15 (super +0.17) (sub -0.10) and an orbital inclination of i=64 degrees (super +4 degrees ) (sub -7 degrees ) . The 95% confidence level lower limit on the inclination of i>49 degrees implies that this planetary system can be detected and studied via radial velocity measurements using a telescope of > or = approximately 30 m aperture.

Unlike some current sequencing approaches, the genome of the unknown target remains intact in this method. The transposition reaction, DNA repair, and subsequent sequencing were performed entirely in vitro, without the need for transformation into bacteria, and resulted in sequence homology with the plasmid DNA target. This approach can reduce the time required for the assay by more than a day compared with standard techniques and reduces the number of required enzymatic steps. In addition, the in vitro method enables transposition to be carried out in automated microfluidic platforms without the need for significant sample manipulation. As a demonstration of incorporating transposition techniques into high-throughput technologies, single transposition reactions were carried out in picoliter-sized droplets generated on a microfluidic platform.

Living colonies of E. rostrata have been collected using the PISCES submersibles from three locations from 480 to 788 m water depth in the Line Islands ( nearly equal 160 degrees W) in the Equatorial Pacific. We have applied to these colonies a high sensitivity, low blank technique to determine U-series ages in small quantities (70 + or - 15 mg) of modern and near modern calcareous skeletons using MC-ICP-MS (Multi-collector Inductively Coupled Plasma Mass Spectrometer). The application of this method to living slow-growing colonies from a range of sites as well as the observations of axial growth patterns in thin sections of their skeletons offer the first expanded and well constrained data on longevity, growth pattern and mean growth rates in E. rostrata. Absolute dated specimens indicate life spans of colonies ranging from 209 + or - 8 yrs to 605 + or - 7 yrs with radial growth rates from 0.012 to 0.072 mm yr (super -1) and vertical extension rates from 0.6 to 1.9 mm yr (super -1) . The linear growth rates reported here are lower than those reported for other deep-sea scleractinian corals (Lophelia pertusa and Madrepora oculata). The U-series dating indicates that the growth ring patterns of E. rostrata are not consistent with annual periodicity emphasizing the importance of absolute radiometric dating methods to constrain growth rates. Slow accretion and extreme longevity make this species and its habitat especially vulnerable to disturbances and impacts from human activities. This dating method combined with observation of growth patterns opens up new perspectives in the field of deep-sea corals since it can provide quantitative estimates of growth rates and longevity of deep-sea corals in general.

The data show no evidence of radiogenic (super 26) Mg and define an upper limit to the abundance of (super 26) Al at the time of particle formation: (super 26) Al/ (super 27) Al 1.7 million years after the oldest solids in the solar system, calcium- and aluminum-rich inclusions (CAIs). The data suggest that high-temperature inner solar system material formed, was subsequently transferred to the Kuiper Belt, and was incorporated into comets several million years after CAI formation.

We report the results of electron microprobe, scanning electron microscopy, and transmission electron microscopy analyses of wadalite-bearing assemblages in the Allende CAIs and propose that wadalite formed by metamorphic reaction between akermanitic melilite and anorthite, likely mediated by chlorine-bearing fluids. Petrographic relationships support the likelihood of multistage alterations by fluids of different chemistries interspersed or coinciding with thermal metamorphic episodes on the Allende parent asteroid. Fluid involvement in metamorphism of Allende CAIs implies that these objects experienced open-system alteration after accretion into the CV chondrite parent asteroid, which may have resulted in disturbances of their oxygen- and magnesium-isotope systematics.

The hominins occur with a macrofauna assemblage that existed in Africa between 2.36 and 1.50 million years ago (Ma). The fossils are encased in water-laid, clastic sediments that were deposited along the lower parts of what is now a deeply eroded cave system, immediately above a flowstone layer with a U-Pb date of 2.026 + or - 0.021 Ma. The flowstone has a reversed paleomagnetic signature and the overlying hominin-bearing sediments are of normal polarity, indicating deposition during the 1.95- to 1.78-Ma Olduvai Subchron. The two hominin specimens were buried together in a single debris flow that lithified soon after deposition in a phreatic environment inaccessible to scavengers.

The model parameterization is a global tessellation of nodes with a velocity profile at each node. Interpolation of the velocity profiles generates a 3D crust and laterally variable upper-mantle velocity. The upper-mantle velocity profile at each node is represented as a linear velocity gradient, which enables travel-time computation in approximately 1 millisecond. This computational speed allows the model to be used in routine analyses in operational monitoring systems. We refine the model using a tomographic formulation that adjusts the average crustal velocity, mantle velocity at the Moho, and the mantle velocity gradient at each node. While the RSTT model is inherently global, our first RSTT tomographic effort covers Eurasia and North Africa, where we have compiled a data set of approximately 600,000 Pn arrivals. Ten percent of the data set is randomly selected and set aside for testing purposes. Travel-time residual variance for the validation data is reduced by 32%. Based on a geographically distributed set of validation events with epicenter accuracy of 5 km or better, epicenter error using 16 Pn arrivals is reduced by 46% from 17.3 km (ak135 model) to 9.3 km (RSTT model) after tomography. The median uncertainty ellipse area is reduced by 68% from 3070 km (super 2) (ak135) to 994 km (super 2) (RSTT), and the number of ellipses with area less than 1000 km (super 2) , which is the area allowed for onsite inspection under the Comprehensive Nuclear Test Ban Treaty, is increased from 0% (ak135) to 51% (RSTT).

Comparisons were made in terms of modeling phase arrival timing, peak ground-motion amplitudes, and the seismic waveforms. In the simulations we assumed the source parameters reported in the Berkeley Seismological Laboratory (BSL) Moment Tensor Catalog. Broadband seismic data from the Berkeley Digital Seismic Network (BDSN), and strong motion data from the USGS and the California Geological Survey (CGS) strong motion arrays were used in the analysis. The comparison of peak ground velocity (PGV) for both models reveals that both 3D models predict the observed PGV well over four orders of magnitude, and P- and S-wave timing and pseudospectral acceleration (PSA) are well modeled by the 3D structure. While the revised model (model 8.3.0) significantly improved the timing of the first arrival, and the waveform fit is generally good, there remain discrepancies in estimated amplitudes and durations that require improvements to the structure. Nevertheless, from our low-frequency (0.5 Hz) analysis we found that the 3D model is suitable for the simulation of PGV to assess the strong shaking hazard of future large earthquakes, because earthquakes larger than M 6 have PGV carried by waves of 1 to several seconds period.

Regional arrival-time observations of 74 Nevada Test Site explosions with known locations comprise the test data set. We investigate epicenter accuracy as a function of the number of events in the multiple-event system that are constrained at the known hypocenter (calibration), the effect of distance between calibration and unconstrained events, and the use of velocity models with varying travel-time prediction accuracy. Further, we test the utility of using a posteriori travel-time residuals to assess location and travel-time prediction accuracy. We find that constraining one event at the known hypocenter reduces epicenter error for all other events by 58% on average compared to locations produced without constraining events. The incremental improvement in epicenter accuracy rapidly diminishes as more hypocenters are constrained, and incremental location improvement is minimal when the number of constrained hypocenters exceeds 10. Events closest to a constrained event exhibit small location bias. Distinct epicenter bias occurs when the distance between the calibration event and the relocated event is greater than a few tens of kilometers. Last, we confirm that metrics based on a posteriori travel-time residuals are poor indicators of both epicenter accuracy and velocity model-based travel-time prediction accuracy.

2010-082293 AB - Palynological results from Julietta Lake currently provide the most direct evidence to support the existence of a glacial refugium for Pinus pumila in mountains of southwestern Beringia. Both percentages and accumulation rates indicate the evergreen shrub survived until at least approximately 19,000 (super 14) C yr BP in the Upper Kolyma region. Percentage data suggest numbers dwindled into the late glaciation, whereas pollen accumulation rates point towards a more rapid demise shortly after approximately 19,000 (super 14) C yr BP. Pinus pumila did not re-establish in any great numbers until approximately 8100 (super 14) C yr BP, despite the local presence approximately 9800 (super 14) C yr BP of Larixdahurica, which shares similar summer temperature requirements. The postglacial thermal maximum (in Beringia approximately 11,000-9000 (super 14) C yr BP) provided Pinus pumila shrubs with equally harsh albeit different conditions for survival than those present during the LGM. Regional records indicate that in this time of maximum warmth Pinus pumila likely sheltered in a second, lower-elevation refugium. Paleoclimatic models and modern ecology suggest that shifts in the nature of seasonal transitions and not only seasonal extremes have played important roles in the history of Pinus pumila over the last approximately 21,000 (super 14) C yr BP.

The concerns extend to the presence of Cr(VI) in many aquifers in California and elsewhere, where relatively high levels have been attributed to both industrial pollution and natural processes. The authors have, therefore, determined if natural redox processes contribute to the presence of high Cr(VI) concentrations (6-36 mu g L (super -1) ) in an aquifer in central California relative to non-detectable concentrations (<0.1 mu g L (super -1) ) in an adjacent aquifer. Specifically, the distribution and the redox speciation of dissolved (<0.45 mu m) Cr have been compared with those of particulate Mn and Fe oxy-hydroxides in sediments, using X-ray absorption spectroscopy at the Mn and Fe L-edges. The analyses show a correlation between the presence of dissolved Cr(VI) and Mn (hydr)oxide minerals, which are the only common, naturally occurring minerals known to oxidize Cr(III) in laboratory experiments. This covariance substantiates the results of those experiments and previous field studies that indicate natural oxidation mechanisms might account for the relatively high levels of Cr(VI) in the study site, as well as for elevated concentrations in other aquifers with similar biogeochemical conditions.

Natural variations in this ratio have been shown in previous studies. In this study, data obtained from uranium ore concentrates of mining facilities around the world show clear evidence that the depositional redox environment in which uranium is precipitated is the primary factor affecting (super 238) U/ (super 235) U fractionation. Low-temperature uranium deposits are, on average, isotopically nearly equal 0.4 ppm heavier than uranium deposited at high temperatures or by non-redox processes. (super 238) U/ (super 235) U ratios coupled with (super 235) U/ (super 234) U ratios in the same sample provide evidence that the redox transition (U (super VI) --> U (super IV) ) at low temperatures is the primary mechanism of (super 238) U/ (super 235) U fractionation and that aqueous alteration plays a very limited, if any, role in fractionation of the (super 238) U/ (super 235) U ratio. The isotopic variation of U is therefore a potential signature that can be used to trace the origin of uranium ore concentrate.

13545820 AB - The majority of carbon sinking out of surface waters is in the form of particles derived from phytoplankton cells (whether live or dead). The activity of hydrolytic enzymes from bacteria attached to those particles affects their sinking rates. Most abundant heterotrophic marine bacteria remain uncultivated, making it difficult to uncover their biogeochemical roles and to understand their interactions with other microbial organisms, including phytoplankton. Using a bead array hybridization assay, we examined the relative abundance of 12 bacterial taxa detectable from amplified 16S rDNA from particles collected during a dense dinoflagellate bloom. A total of 37 coastal surface water samples spanning 2 months were examined. Targeted taxa included 16S phylotypes belonging mostly to clades within the alpha Proteobacteria (especially Roseobacter) and Bacteroidetes groups. Using these data, we addressed two questions. First, did different bacterial taxa exhibit variation in their attachment to algal cells over time, suggesting different ecological roles? Second, did 16S phylogeny predict ecological role (i.e. did taxa closely related to one another display similar dynamics in attachment)? We found that bacterial taxa revealed distinct temporal dynamics of attachment, suggesting different ecological roles. Some taxa increased attachment following the end of the bloom, consistent with a saprophytic lifestyle. Other taxa increased their attachment during the early stage of the bloom, suggesting a mutualistic (or commensal) relationship with the algae. Yet other taxa increased their attachment at the peak of the bloom (and during bloom decline), suggesting either a response to unhealthy algal cell or a parasitic interaction. The types of interactions did not follow phylogeny, suggesting that similarity of 16S sequence among taxa may not always be useful to predict ecological role.

Demographic information and cigarette smoking data were obtained via questionnaire. There were 119 Caucasian Americans, 118 African Americans, and 2 Asian Americans. The average maternal age was 24.9Ac5.8 (meanAcS.D.) years. Thirty-nine percent of the Caucasian Americans and 45.4% of the African Americans self-reported that they were active smokers during the index pregnancy. The average number of cigarettes smoked per day was 2.65Ac5.75 and 1.37Ac3.17 for Caucasian and African American mothers, respectively. Peripheral blood lymphocytes from the mother and from the fetal side of the placenta were evaluated for chromosome aberrations by whole chromosome painting. Aliquots from the same blood samples were also used to assess genetic susceptibility with an in vitro bleomycin challenge assay. Spontaneous translocation frequencies in both maternal and newborn lymphocytes were not associated with cigarette smoking, socioeconomic status, or education. The absence of a smoking effect may be attributable to the low level of cigarette usage in these subjects. The average bleomycin-induced damage in the maternal and newborn populations was 0.37Ac0.27 and 0.15Ac0.14 breaks per cell, respectively, a difference that was highly significant (p <0.0001). In newborns there was a positive association between bleomycin sensitivity and the frequencies of aberrations as measured by chromosome painting: p a[control][curren]0.0007 for dicentrics and fragments, and p a[control][curren]0.002 for translocations. Caucasian American newborns demonstrated a significant association between dicentrics and fragments as measured by painting, and bleomycin sensitivity (p a[control][curren]0.0002), but no such association was observed for African American newborns. The results of this study indicate that while differences were observed between African Americans and Caucasian Americans, race does not appear to be a major contributor to chromosome damage in newborns or their mothers. However, peripheral lymphocytes in pregnant women are more susceptible to genetic damage than peripheral lymphocytes in newborns.

The GRA meteorites contain high abundances of sodic plagioclase, relatively Fe-rich pyroxenes and olivine, abundant phosphates, and low temperature alteration. They represent products of very early planetesimal melting (4565.9 + or - 0.3 Ma) of an unsampled geochemical reservoir from an asteroid that has characteristics similar to the brachinite parent body. The magmatism represented by these meteorites is contrary to the commonly held belief that the earliest stages of melting on all planetary bodies during the first 2-30 Ma of solar system history were fundamentally basaltic in nature. These sodic plagioclase-rich rocks represent a series of early asteroidal high-temperature processes: (stage 1) melting and partial extraction of a low-temperature Fe-Ni-S melt, (stage 2) small degrees of disequilibrium partial melting of a sodium- or alkali-rich chondritic parent body with additional incorporation of Fe-Ni-S melt that was not fully extracted during stage 1, (stage 3) volatile-enhanced rapid extraction and emplacement of the Na-rich, high-normative plagioclase melt, (stage 4) final emplacement and accumulation of plagioclase and phosphates, (stage 5) subsolidus reequilibration of lithology between 962 and 600 degrees C at an fO (sub 2) of IW to IW + 1.1, and (stage 6) replacement of merrillite and pyroxene by Cl-apatite resulting from the interaction between magmatic minerals and a Cl-rich fluid/residuum melt. The subsolidus events started as early as 4561.1 Ma and may have continued for upwards of 144 million years. The existence of assemblages similar to GRA on several other planetary bodies with different geochemical characteristics (ureilite, winonaites, IAB irons) implies that this type of early asteroidal melting was not rare. Whereas, eucrites and angrites represent extensive melting of a parent body with low concentrations of moderately-volatile elements, GRA represents low-degrees of melting of a parent body with chondritic abundances of moderately volatile elements. The interpretation of the low-temperature mineral assemblage is somewhat ambiguous. Textural features suggest multiple episodes of alteration. The earliest stage follows the interaction of magmatic assemblages with a Cl-rich fluid. The last episode of alteration appears to cross-cut the fusion crust and earlier stages of alteration. Stable isotopic measurements of the alteration can be interpreted as indicating that an extraterrestrial volatile component was preserved in GRA.

The aftershock model designed by Reasenberg and Jones (1989, 1994) allows for a probabilistic statement of earthquakelike aftershock behavior at any time after the mainshock. We use this model to define two types of aftershock discriminants. The first defines M (sub X) , or the minimum magnitude of an aftershock expected within a given duration after the mainshock with probability X. Of the 67 earthquakes with M>4 in the study region, 63 of them produce an aftershock greater than M (sub 99) within the first 7 days after a mainshock. This is contrasted with only six of 93 explosions with M>4 that produce an aftershock greater than M (sub 99) for the same period. If the aftershock magnitude threshold is lowered and the M (sub 90) criteria is used, then no explosions produce an aftershock greater than M (sub 90) for durations that end more than 17 days after the mainshock. The other discriminant defines N (sub X) , or the minimum cumulative number of aftershocks expected for a given time after the mainshock with probability X. Similar to the aftershock magnitude discriminant, five earthquakes do not produce more aftershocks than N (sub 99) within 7 days after the mainshock. However, within the same period, all but one of the explosions produce fewer aftershocks than N (sub 99) . One explosion is added if the duration is shortened to 2 days after the mainshock. The cumulative number aftershock discriminant is more reliable, especially at short durations, but requires a low magnitude of completeness for the given earthquake catalog. These results at NTS are quite promising and should be evaluated at other nuclear test sites to understand the effects of differences in the geologic setting and nuclear testing practices on its performance.

AN - 733713559; 19896956 AB - DNA double-strand breaks (DSB) are generally considered the most critical lesion induced by ionizing radiation (IR) and may initiate carcinogenesis and other disease. Using an immunofluorescence assay to simultaneously detect nuclear foci of the phosphorylated forms of histone H2AX and ATM kinase at sites of DSBs, we examined the response of 25 apparently normal and 10 DNA repair-deficient (ATM, ATR, NBN, LIG1, LIG4, and FANCG) primary fibroblast strains irradiated with low doses of (137)Cs gamma-rays. Quiescent G(0)/G(1)-phase cultures were exposed to 5, 10, and 25 cGy and allowed to repair for 24h. The maximum level of IR-induced foci (0.15 foci per cGy, at 10 or 30 min) in the normal strains showed much less inter-individual variation (CV approximately 0.2) than the level of spontaneous foci, which ranged from 0.2-2.6 foci/cell (CV approximately 0.6; mean+/-SD of 1.00+/-0.57). Significantly slower focus formation post-irradiation was observed in seven normal strains, similar to most mutant strains examined. There was variation in repair efficiency measured by the fraction of IR-induced foci remaining 24h post-irradiation, curiously with the strains having slower focus formation showing more efficient repair after 25 cGy. Interestingly, the ranges of spontaneous and residual induced foci levels at 24h in the normal strains were as least as large as those observed for the repair-defective mutant strains. The inter-individual variation in DSB foci parameters observed in cells exposed to low doses of ionizing radiation in this small survey of apparently normal people suggests that hypomorphic genetic variants in genomic maintenance and/or DNA damage signaling and repair genes may contribute to differential susceptibility to cancer induced by environmental mutagens.

Site-specific accumulation data, such as these, are prerequisite to the application of meteoric (super 10) Be in surface process studies. Our data begin the process of calibrating long-term meteoric (super 10) Be delivery rates across latitude and precipitation gradients. Our integrated rate is lower than contemporary meteoric (super 10) Be fluxes measured in New Zealand rainfall, suggesting that long-term average precipitation, dust flux, or both, at this site were less than modern values. With accurately calibrated long-term delivery rates, such as this, meteoric (super 10) Be will be a powerful tool for studying rates of landscape change in environments where other cosmogenic nuclides, such as in situ (super 10) Be, cannot be used.

In the applied finite difference framework and for a fixed problem size per processor, this results in a maximum number of approximately 8 X 10 (super 9) grid cells (unknowns). Detailed timing information shows that the applied simulation platform ParFlow exhibits excellent parallel efficiency. This study demonstrates that regional scale hydrologic simulations on the order of 10 (super 3) km (super 2) are feasible at hydrologic resolution ( approximately 10 (super 0) -10 (super 1) m laterally, 10 (super -2) -10 (super -1) m vertically) with reasonable computation times, which has been previously assumed to be an intractable computational problem.

The structures are characterized by magnetic field enhancements and rotations characteristic of magnetic flux ropes, and characteristic ionospheric electron energy distributions with angular distributions distinct from surrounding regions. These observations indicate that significant amounts of atmosphere are intermittently being carried away from Mars by a bulk removal process: the top portions of crustal field loops are stretched through interaction with the solar wind and detach via magnetic reconnection. This process occurs frequently and may account for as much as 10% of the total present-day ion escape from Mars.

The model is developed through simultaneous inversion of seismic body wave travel times (P and S) and geodynamic observations while using realistic mineral physics parameters linking wave speeds and density. Geodynamic observations include the global free air gravity field, divergence of the tectonic plates, dynamic topography of the free surface, and the flow-induced excess ellipticity of the core-mantle boundary. GyPSuM is built with the philosophy that heterogeneity that most closely resembles thermal variations is the simplest possible solution. Models of the density field from Earth's free oscillations have provided great insight into the density configuration of the mantle but are limited to very long wavelength solutions. Alternatively, scaling higher-resolution seismic images to obtain density anomalies generates density fields that do not satisfy geodynamic observations. The current study provides a 3-D density model for the mantle that directly satisfies geodynamic and seismic observations through a joint seismic-geodynamic inversion process. Notable density field observations include high-density piles at the base of superplume structures, supporting the general results of past normal mode studies. However, we find that these features are more localized and have lower amplitude than past studies would suggest. When we consider both fast and slow seismic anomalies in GyPSuM, we find that P and S wave speeds are strongly correlated throughout the mantle. However, we find a low correlation of fast S wave zones in the deep mantle (>1500 km depth) with the corresponding P wave anomalies, suggesting a systematic divergence from simplified thermal effects in ancient subducted slab anomalies. The cratonic lithosphere and D" regions are shown to have strong compositional signatures. However, we argue that temperature variations are the primary cause of P wave speed, S wave speed, and density anomalies throughout most of the mantle.

One of the principal Quaternary landscape features of the eastern Sierra El Mayor-Sierra Cucapa is a prominent surface that slopes approximately 1-2 degrees eastward towards the Colorado River Delta. Along the eastern side of the Sierra El Mayor and facing the Colorado River delta, but not along other piedmont mountain fronts that face the delta, this surface is terminated by a series of stepped terrace surfaces. The terrace surfaces are cut into fluvial-deltaic deposits from the Colorado River delta system and are capped by approximately 1 m thick gravels. Optically stimulated luminescence ages from interbedded coarse sands in the capping gravels of the upper surface and two of the inset terraces range from approximately 17 to 31 ka (average 24+ or -3 ka) but lack a systematic age trend from upper to lower surface. The underlying fluvial-deltaic deposits have older optically stimulated luminescence ages of 31 to 39 ka and suggest Colorado River delta deposition during the relatively stable interstadial of the Middle Wisconsinan substage (Marine Isotope Stage 3) when sea level was ca -60 to -80 m. Samples from depth-profiles in the capping gravels and from the top of the upper surface have a mean (super 10) Be terrestrial cosmogenic nuclide age of 59+ or -5 ka. When corrected for inheritance, an average age of approximately 21 ka is computed for exposure of the capping gravels on the upper surface and inset terraces, which is in the range of the optically stimulated luminescence burial ages. Both the upper surface and inset terraces formed 17-30 ka at a transition time from dry to relatively wet climate when increased aggradation caused alluvial fan development on the upper surface. Regionally, these surfaces correlate with the Q2c-Q3a age deposits of the southwestern North America alluvial fan and terrace deposits. Sea level was also falling rapidly at this time, which may have caused the Colorado River to become entrenched near the range front thus allowing rapid response and down-cutting to form the inset terraces on the east side of the Sierra El Mayor facing the delta. Assuming the 34 ka delta deposits graded to a base level that was -60 to -80 m during Marine Isotope Stage 3, the computed surface uplift rate for the eastern side of the Sierra El Mayor is approximately 2.1-2.7 mm/yr. This uplift may be accommodated on a fault or fault system that is a southward extension of the Mexicali spreading and seismic zone that is buried beneath the Colorado River delta east of the Sierra El Mayor. The uplift rates from this study are consistent with geologic and geodetic data for the Sierra El Mayor and Sierra Cucapa, and account for much of the missing extensional strain across the area.

Gas fluxes are taken from porous flow models of warming Arctic sediment. Plume spread parameters are then used to bracket the volume of dilution. Consumption stoichiometries for the marine methanotrophs are based on growth efficiency and elemental/enzyme composition data. The nutritional demand implied by extra CH (sub 4) removal is compared with supply in various high latitude water masses. For emissions sized to fit the shelf break, reaction potential begins at one hundred micromolar and falls to order ten a thousand kilometers downstream. Oxygen loss and carbon dioxide production are sufficient respectively to hypoxify and acidify poorly ventilated basins. Nitrogen and the monooxygenase transition metals may be depleted in some locations as well. Deprivation is implied relative to existing ecosystems, along with dispersal of the excess dissolved gas. Physical uncertainties are inherent in the clathrate abundance, patch size, outflow buoyancy and mixing rate. Microbial ecology is even less defined but may involve nutrient recycling and anaerobic oxidizers.

Interaction with rough topography causes significant P-to-Rg scattering along the surface with amplification of high-frequency (2-8 Hz) shear waves relative to the flat Earth case. Shear waves of different polarizations are coupled by topographic scattering. Rg precursors composed of P-to-Rg conversions traveling as surface waves have the spectral amplitudes comparable to the P wave, while the Rg phase has the low-frequency (0.5-3 Hz) spectral shape of the Rg from the flat case plus the high-frequency (3-8 Hz) P wave spectra. Motions at near-vertical takeoff angles corresponding to teleseismic propagation are increased or decreased indicating that waves are focused or defocused by topographic features above the source. Topographic roughness has a dramatic effect as short-wavelength features <2-5 km) are included. Higher frequencies are amplified by topography, including frequencies corresponding to wavelengths shorter than the shortest topographic scale length. Overall topography enhances energy propagating along the surface near the source, amplifies surface waves, and tends to balance SV- and SH-polarized motions, all of which impact shear wave observations used for nuclear explosion monitoring. Further simulation studies could elucidate how the wavefield emerging from a topographically rough area ultimately propagates to regional and/or teleseismic distances.

(super 10) Be cosmogenic radionuclide (CRN) dating of embedded cobbles is used to constrain the age of offset alluvial surfaces. At the first site a 48 + or - 7 m offset alluvial fan, for which (super 10) Be CRN model ages average 11.1 + or - 4.3 ka, yield a slip rate of 5.4 + or - 2.7 mm/a, with conservative bounds of 1.3-16.4 mm/a. At the second site the scattered distributions of the (super 10) Be CRN ages from an offset bajada attest to the complex processes involved in sediment transport and emplacement. There, two offsets were identified. The 160 + or - 8 m offset of an incised alluvial fan dated at 37 + or - 5 ka shows a slip rate of 4.5 + or - 0.9 mm/a, with a conservative minimum value of 3.2 mm/a. A larger offset, 626 + or - 37 m, is derived from a prominent channel incised into the bajada. Cobbles from the bajada surface have ages from 33 to 141 ka, with a mean of 87 + or - 26 ka. A slip rate of 8.1 + or - 2.9 mm/a is derived from the mean age, with conservative bounds of 3.8-22.1 mm/a. These results and other published slip rates along the linear WAF segment, from GPS to geological time scales, lack the resolution to fully resolve the question of temporal variations versus consistency of the fault slip rate of the WAF. Yet, given the uncertainties, they are not inconsistent with each other.

The joint inversion benefits from both better resolution and wider data coverage than when using only individual data sets. Resolution tests confirm that the joint inversion yields good resolution ranging from the Moho to a depth of 1400 km. The complementary and overlapping nature of the different data sets' resolving power has reduced disparities in resolving power that exist for individual data sets, for example between resolving power for crustal and lower-mantle structure. This increases the utility of the new tomographic model for explaining and predicting a variety of observations and dynamics. The new model derived from the joint inversion assembles a large number of mantle structures known from a wide variety of previous studies into one model and in some cases reconciles different local studies that previously seemed contradictory. Finally, the model shows that shallow low-velocity anomalies beneath the Pannonian basin and the Iranian plateau are connected to similar anomalies in the transition zone, the latter possibly related to a deep dehydration process in the subducted lithosphere of the Neo-Tethys Ocean. The model shows the Hellenic slab penetrating the lower mantle, the Calabrian slab extending flatly in the transition zone, and discontinuous slabs beneath the Apennines and the Zagros belt.

The Luzon ridge near the Batan islands is represented by an idealized ridge with a height of 2.6 km on a flat bottom. Model runs are performed for various ridge shapes and (a)symmetric tidal forcings. The model is in the mixed tidal lee wave regime. The barotropic tide over the ridge generates first-mode waves through the internal tide release mechanism. Westward-traveling solitons emerge from these first-mode waves through nonlinear steepening. In the internal tide release mechanism, asymmetric tides with strong eastward currents can generate strong westward solitons. The eastward current creates an elevation wave with a higher energy density west of the ridge, and as soon as the current slackens, the wave is released westward. On its backslope strong solitons develop. The energy density is further enhanced by nonlinearities, such as differences in phase speeds and energy fluxes related to lee waves. A modal and harmonic decomposition shows the generation of vertical modes and higher temporal harmonics and indicates significant wave-wave interaction (e.g., triads). In the mixed tidal lee wave regime, more energy is contained in the first mode compared to the higher modes. Hence, linear internal tide beams are less well defined and strong solitons develop.

The addition of 0.1 wt% ( approximately 0.16 vol%) C causes series-type grain boundary impedance in the samples that slightly decreases the bulk conductivity of the system. In contrast, the addition of 1.0 vol% sulfide results in conductivity much higher than plain olivine, but still lower than that of a fully interconnected sulfide phase. The sulfide is partially connected on the grain boundaries and edges and has reached the electrical percolation threshold. The effect adding sulfide is similar to the effect of adding 0.01%-0.1% H to olivine. It may not always be necessary to have hydrogen or connected melt or fluid to account for anomalously high conductivity in some parts of the mantle or crust.

A new procedure, exhaled breath vapor (EBV) collection, involving the active sampling and preconcentration of a breath sample with a SPME fiber fitted inside a modified commercial breath-collection device, the RTubeTM, is described. Immediately after sample collection, compounds are desorbed from the SPME fiber at 250 C in the GC-MS injector. Experiments were performed using EBV collected at -80 C and at room temperature, and the results compared to the traditional method of collecting exhaled breath condensate at -80 C followed by passive SPME sampling of the collected condensate. Methods are compared in terms of portability, ease-of-use, speed of analysis, and detection limits. The need for a clean air supply for the study subjects is demonstrated using several localized sources of VOC contaminants including nail polish, lemonade, and gasoline. Various simple methods to supply clean inhaled air to a subject are presented. Chemical exposures are used to demonstrate the importance of providing cleaned air (organic vapor respirator) or an external air source (tubing stretched to a separate room). These techniques allow for facile data interpretation by minimizing background contaminants. It is demonstrated herein that this active SPME breath-sampling device provides advantages in the forms of faster sample collection and data analysis, apparatus portability and avoidance of power or cooling requirements, and performance for sample collection in a contaminated environment.

We propose that across-arc differences in the geochemistry of Izu-Bonin arc basalts are controlled by the addition of aqueous slab fluids to the volcanic front and hydrous partial melt of the slab to the back arc. The volcanic front has the lowest concentrations of incompatible elements, the strongest relative enrichments of fluid-mobile elements, and the most radiogenic Sr, Nd, Hf, and Pb, suggesting the volcanic front is the result of high degrees of partial melting of a previously depleted mantle source caused by an aqueous fluid flux from the slab. Relative to the volcanic front, the back arc has higher concentrations of incompatible elements and elevated La/Yb and Nb/Zr, suggesting lower degrees of partial melting of a less depleted or even enriched mantle source. Positive linear correlations between fluid-immobile element concentrations and the estimated degree of mantle melting suggest the slab contribution added to the mantle wedge in the Izu back arc is a supercritical melt. Pb, Nd, and Hf isotopes and Th/La systematics of back-arc basalts are consistent with a slab melt composed of >90% altered oceanic crust and <10% sediment; that is, altered oceanic crust, not subducted sediment, dominates the slab contribution. High field strength element systematics require supercritical melts to be in equilibrium with residual rutile and zircon.

We tested the effects of two common forest management practices, fertilization and competing vegetation control using herbicides, on surface SOM distribution and stability characteristics in three ponderosa pine (Pinus ponderosa P. Lawson & C. Lawson) plantations of differing productivity, soil type, and parent material in northern California by using density fractionation and aerobic laboratory incubation of the surface soils. The treatment effects on pine productivity revealed responses dominated by moisture limitation at the less productive sites and by nutrient limitation at the most productive site. The stability of surface SOM increased with increasing site productivity. Fertilization increased N concentrations and decreased C/N ratios in whole soils and light fractions at the less productive sites, and the effects persisted for more than a decade. Furthermore, fertilization increased soil C mineralization from the intermediate-productivity site during incubation. In contrast, fertilization decreased C mineralization from the most productive site, suggesting that fertilization increased SOM stabilization at this site. Controlling understory vegetation with herbicides reduced N availability, as evidenced by reduced light-fraction N at the poorest site and decreased N mineralization during incubation. Our study demonstrates the importance of site characteristics and the use of a combination of indices in determining the effects of forest management practices on SOM characteristics and dynamics.

The knowledge of the crustal structure, lithosphere-asthenosphere boundary and mantle transition zone between two seismic discontinuities at depths "410" and "660" km, is one of the most important issues to understand the Earth's dynamics. To create a mantle model of the TESZ and surroundings we used different seismic data collected along the 950 km long POLONAISE'97 profile P4. Previous results of 2-D ray-tracing and P-wave travel time modelling and new results of P-wave travel time residuals methods and receiver function sections provide facts about the seismic structure from the surface down to 900 km depth. In the TESZ a large basin, about 125 km wide, is filled with sedimentary strata (Vp 7.0 km s (super -1) ) along most of the P4 profile. However, lower values to the southwest may indicate the termination of Baltica. High velocity ( nearly equal 8.35 km s (super -1) ) uppermost mantle lies beneath the Avalonia/Variscan terranes, and may be due to rifting and/or subduction. The seismic lithosphere thickness for the EEC is about 200 km, while it is only 90 km in the Palaeozoic platform (PP). The mantle transition zone is shallower and about 30 km thicker under the EEC, which could be due to thermal conditions (lower temperature) and/or the presence of water and FeO. The result of this paper is a new compiled and integrated seismic velocity model, available in digital form down to 900 km depth (http://www.igf.fuw.edu.pl/p4-mantle), which can be used as a preliminary model of the crust and upper mantle in the TESZ area in Central Europe.

These data, covering a vertical section of almost 65 km, are used in conjunction with surface heat flow to generate a detailed and comprehensive lithospheric thermal model that reflects the conditions of the Arabian Shield (AS) prior to the post-Oligocene onset of lithosphere thinning and voluminous basaltic volcanism. The pre-Miocene model geotherms, based on conductive surface heat flows of 55 and 60 mW m (super -2) , (a) meet the range of lithosphere-asthenosphere boundary depths of 110-160 km known from seismology, (b) conform to results of thermomechanical models on the origin of the Dead Sea basin that started in Miocene time, and (c) are consistent with typical xenolith-derived geotherms for terranes of similar age and lithospheric thickness. Moho temperatures (at depths between 35 and 40 km) of the AS in pre-Miocene times were most likely in the order of 530-650 degrees C, with mantle heat flows averaging between 24 and 29 mW m (super -2) . Results contradict former views of the late Proterozoic/early Cambrian-stabilized AS being an anomalously cold terrane. A "cold" thermal structure inferred from previously measured low surface heat flows (generally < or =45 mW m (super -2) ) is inconsistent with the thickness, composition, and petrophysical properties of the stable lithosphere of the shield.

The model is constrained by simultaneously inverting global seismic and mantle convection data sets and it includes an explicit treatment of the positive chemical buoyancy of the continental tectosphere. Moreover, it adopts a depth-dependent mantle viscosity structure which reconciles both glacial isostatic adjustment (GIA) and convection data. The flow model successfully reproduces plate velocities and observations of surface gravity and topography, including the continent-scale quasi-linear depression (after corrections for GIA and crustal heterogeneity) extending from northern Alaska to Venezuela. The predictions also match lithospheric flow and stress fields inferred from local and regional measurements of seismic anisotropy and surface deformation. We demonstrate that these signals are largely driven by viscous flow coupled to density anomalies in the deep portions of the upper mantle and within the lower mantle, where the latter may be associated with the descent of the ancient Kula-Farallon plate system and an active mantle upwelling below the Pacific margin of the North American plate. More importantly, the flow calculations elucidate how these large-scale heterogeneities give rise to regional-scale flow and stress patterns below the southwestern U.S. and below the central U.S. JF - Tectonophysics AU - Forte, A M AU - Moucha, R AU - Simmons, N A AU - Grand, S P AU - Mitrovica, Jerry X A2 - Pasyanos, M.

We have measured synchrotron Mossbauer spectroscopy (SMS), X-ray emission spectroscopy (XES), and X-ray diffraction (XRD) of Pv with all iron in Fe (super 3+) in the laser-heated diamond-anvil cell to over 100 GPa. Fe (super 3+) increases the anisotropy of the Pv unit cell, whereas Fe (super 2+) decreases it. In Pv synthesized above 50 GPa, Fe (super 3+) enters into both the dodecahedral (A) and octahedral (B) sites approximately equally, suggesting charge coupled substitution. Combining SMS and XES, we found that the LS population in the B site gradually increases with pressure up to 50-60 GPa where all Fe (super 3+) in the B site becomes LS, while Fe (super 3+) in the A site remains HS to at least 136 GPa. Fe (super 3+) makes Pv more compressible than Mg-endmember below 50 GPa because of the gradual spin transition in the B site together with lattice compression. The completion of the spin transition at 50-60 GPa increases bulk modulus with no associated change in density. This elasticity change can be a useful seismic probe for investigating compositional heterogeneities associated with Fe (super 3+) .

We here present a continent wide study of the Australian crust based on the exploitation of continuous data from extensive portable broad-band deployments across Australia and the permanent stations. Permanent stations play a valuable role in linking the information from different portable deployments. Over 2000 Rayleigh wave components of the Green's functions are extracted from the inter-station cross-correlations and provide a reasonably uniform sampling of the continent. Rayleigh wave group velocities are extracted for the period range from 5 s to 12.5 s. The group dispersion from the various paths are inverted to produce group wavespeed maps based on a 2 degrees x 2 degrees grid using a nonlinear-iterative 2-D tomographic scheme with updating of propagation paths using the fast marching method. The group wavespeed maps display prominent features with lowered wavespeeds. For the shortest periods these features are mostly associated with the regions of thick sedimentary sequences, such as the Amadeus and Officer basins in central Australia. At the longer periods reduced wavespeeds are most likely due to elevated temperatures and link well to estimates of crustal heat flow. The major cratonic blocks show faster group wavespeeds, and the Archaean cratons of Western Australia are particularly fast with some indication of internal structure linked to terrane boundaries. The transition from the Precambrian core of the continent, in the centre and west, to the Phanerozoic fold belts in the east is not marked by any single well-defined anomaly in the crust, even though distinctive contrasts have been mapped in the mantle lithosphere from surface wave tomography.

And modeling is substantiated via completely independent methods. In 1996-1997 our 130 seismographs constituted the largest seismic antenna ever in Europe. The Tor area was chosen along a well studied crustal profile of an earlier project, and the modeling efforts were concentrated on the deep lithosphere and asthenosphere differences to depths around 300 km. The Tor data have been subjected to P-wave travel time tomography, surface wave and receiver function analysis as well as anisotropy and scattering measurements. An important goal of the project was to make several independent inversions of the tomography data, and compare the results in an attempt to evaluate uniqueness, resolution and accuracy of these inversions. The comparisons of this paper involve more diversity in methods than any previous comparison. The geological outcome is a substantiation of earlier statements that: "The transition is interpreted to be sharp and steep in two places. It goes all through the lithosphere at the northern rim of the Tornquist Zone near the border between Sweden and Denmark, and here the lithosphere difference is large to depths more than 200 km. The other lithosphere difference, of smaller scale, is found near the southern edge of the Ringkobing-Fyn High near the border between Denmark and Germany. Also this transition is sharp and steep, and goes all through the lithosphere to depths around 120 km. These two sharp transitions divide the Tor region into 3 different lithosphere structures distinguishable in P-wave travel time tomography, surface wave dispersion, P- and S-wave anisotropy and partly in P-wave scattering". The mentioned broad-scale features are judged to be unambiguously determined, with well-described resolution and accuracy. Unfortunately a detail like the slope of the subcrustal lithosphere transition right under the Tornquist Zone cannot be constrained even if this is where the resolution is best, and the curiosity largest.

Geodynamic studies suggest that the rheological contrast between the deep continental and oceanic upper mantle is a key factor that controls the longevity of the continental roots. Current understanding of rheological properties of deep upper mantle is reviewed to examine how a large enough rheological contrast between the continental and oceanic upper mantle develops that leads to the longevity of the deep continental roots. Based on the microstructures of naturally deformed deep continental rocks as well as on the observations of seismic anisotropy, it is concluded that power-law dislocation creep dominates in most of the deep upper mantle. Deformation by power-law creep is sensitive to water content and therefore the removal of water by partial melting to form depleted continental roots is a likely mechanism to establish a large rheological contrast. The results of experimental studies on the influence of temperature, pressure and water content on plastic flow by power-law dislocation creep are reviewed. The degree of rheological contrast depends critically on the dependence of effective viscosity on water content under "wet" (water-rich) conditions but it is also sensitive to the effective viscosity under "dry" (water-free) conditions that depends critically on the influence of pressure on deformation. Based on the analysis of thermodynamics of defects and high-temperature creep, it is shown that a robust estimate of the influence of water and pressure can be made only by the combination of low-pressure (5 GPa) studies. A wide range of flow laws has been reported, leading to nearly 10 orders of magnitude differences in estimated viscosities under the deep upper mantle conditions. However, based on the examination of several criteria, it is concluded that relatively robust experimental data are now available for power-law dislocation creep in olivine both under "dry" (water-free) and "wet" (water-saturated) conditions. These data show that the influence of water is large (a change in viscosity up to nearly equal 4 orders of magnitude for a constant stress) at the depth of nearly equal 200-400 km. I conclude that the conditions for survival of a deep root for a few billions of years can be satisfied when "dry" olivine rheology with a relatively large activation volume (>(10-15) x 10 (super -6) m (super 3) /mol)) is used and the substantial water removal occurs to these depths. High degree of water removal requires a large degree of melting in the deep upper mantle that could have occurred in the Archean where geotherm was likely hotter than the current one by nearly equal 200 K presumably with the help of water.

The two-station method is used to compute 124 interstation path-averaged attenuation coefficients within the 15-120 s period range. An adaptation to attenuation coefficients of the Yanovskaya-Ditmar formulation, specifically devoted to path-averaged surface-wave dispersion data and body waves, permits to obtain the local attenuation coefficients and their uncertainties for all the period range, at every node of a grid covering the studied region. Maps of stretching, azimuths and mean radii of the resolution ellipses are also obtained for every period. All of these parameters are strongly related to the spatial path-coverage, data quality and data coherency. A local attenuation dispersion curve is defined then in each grid node and the stochastic inversion of these curves yields 1-D models of inverse shear-wave intrinsic quality factor (Q (sub beta ) (super -1) ). The shear-wave velocity models obtained for every grid node in an elastic tomography developed in a previous work for the same domain are taken as reference models for the inversion process. The kriging contouring algorithm is used to represent the resulting 3-D Q (sub beta ) (super -1) structure by means of horizontal and vertical cross-sections down to 160 km depth. The main patterns of this anelastic structure are mostly in agreement with the structural and tectonic features obtained in the reference shear-velocity tomography. The local attenuation maps manifest notable lateral changes for periods of 20 and 40 s, whereas more moderate spatial variation is observed for longer periods. The 3-D anelastic models show that, at shallow levels, the attenuation in the western Mediterranean is usually slightly higher than in the central-eastern part. The area from Corsica-Sardinia Islands to Italy presents high Q (sub beta ) (super -1) values of 40.0-70.0 x 10 (super -3) down to 75 km depth, whereas Q (sub beta ) (super -1) does not exceed 20.0 x 10 (super -3) in the rest of the Mediterranean basin, except for the south-eastern part, where slightly higher values are obtained (20.0-30.0 x 10 (super -3) ). Those high Q (sub beta ) (super -1) values suggest the presence of asthenospheric material at shallow levels, which would be related to distensive tectonic processes responsible for the recent opening of extensional basins, as the Tyrrhenian Sea and the Ligurian-Provencal basin. In the eastern Mediterranean, the vertical cross-sections at different latitudes and longitudes reveal at deep levels some structural patterns consistent with signs of subduction, which are linked to the convergence between the African and Eurasian plates.

Using recently published dispersion models, we invert surface wave group velocities for lithospheric structure, including lithospheric thickness, over much of the Eastern Hemisphere, encompassing Eurasia, Africa, and the Indian Ocean. Thicker lithospheres under Precambrian shields and platforms are clearly observed, not only under the large cratons (West Africa, Congo, Baltic, Russia, Siberia, India), but also under smaller blocks like the Tarim Basin and Yangtze craton. In contrast, it is found that remobilized Precambrian structures like the Saharan Shield and Sino-Korean Paraplatform do not have well-established lithospheric keels. The thinnest lithospheric thickness is found under oceanic and continental rifts, as well as along convergence zones. We compare our results to thermal models of continental lithosphere, lithospheric cooling models of oceanic lithosphere, lithosphere-asthenosphere boundary (LAB) estimates from S-wave receiver functions, and velocity variations of global tomography models. In addition to comparing results for the broad region, we examine in detail the regions of Central Africa, Siberia, and Tibet. While there are clear differences in the various estimates, overall the results are generally consistent. Inconsistencies between the estimates may be due to a variety of reasons including lateral and depth resolution differences and the comparison of what may be different lithospheric features.

This margin juxtaposes old oceanic lithosphere and a Precambrian continental domain. The model combines within an internally consistent framework data from petrology, mineral physics, and geophysical observables. The calculated mantle temperature and density distributions down to a depth of 400 km are consistent with available xenolith-derived data, and fit simultaneously the observed free-air anomaly, geoid height, surface heat flow, and elevation. The model also explains the anomalously thick oceanic crust and the depletion of the lithospheric mantle in the ocean-continent transition and in the Proterozoic continental domain. Seismic velocities predicted by the present model are in good agreement with values obtained from wide angle reflection/refraction and tomography experiments. The thermal lithospheric thickness is nearly equal 100 km in the oceanic domain, increasing gradually to nearly equal 125 km across the ocean-continent transition and then more sharply to nearly equal 175 km in the continental domain. The density distribution in the mantle differs significantly from current purely thermal approaches where density is assumed to be only temperature-dependent. Non-negligible compositional density differences are encountered between the oceanic, transitional, and continental domains. Results show that non-thermal effects such as composition and phase changes cannot be neglected in models of the upper mantle.

Previous investigations of mantle anisotropy in Central Europe have shown fast directions aligning smoothly with the craton's margin and various suggestions have been proposed to explain their origin such as asthenospheric flow or lithospheric frozen-in deformation. Here, we aim at investigating the continuation of this shear-wave splitting pattern further to the East, into the East European Craton. For the craton, the interpretation appears to be less ambiguous than for central Europe since several arguments support lithospheric anisotropy in this region: 1) The large-scale coherence within either of the four constituting blocks and the significant variations between the blocks on a small-scale, 2) the weak correlation with absolute plate motion vectors, and 3) the good correlation between anisotropy and crustal features, for which we use magnetic field alignments as a proxy. Rather good correlation of these magnetic features with seismic fast orientations strongly supports the idea of vertically coherent deformation throughout upper mantle and crust. The observed splitting orientations thus reflect the last tectonic events of each block, frozen-in into the lithosphere for hundreds of millions of years.

AN - 734170698; 19959945 AB - Radiation doses calculated for people resettling Bikini Island at Bikini Atoll, Enjebi Island at Enewetak Atoll, Rongelap Island at Rongelap Atoll, and Utrōk Island at Utrōk Atoll are presented. Residence is assumed to begin in 2010. In previous dose assessments it was shown that (137)Cs accounts for about 98% of the total dose for returning residents. About 85 to 90% (depending on the atoll) is via consumption of locally grown foods containing (137)Cs, and about 10 to 15% is due to external exposure from (137)Cs in the soil. These assessments were made using only the radiological half-life of (137)Cs (30.1 y). We have shown since that there is an environmental loss of (137)Cs from soil to groundwater that results in a more rapid loss of (137)Cs from the atoll ecosystem. The mean effective half-life of (137)Cs at the atolls is 8.5 y. Moreover, treatment of coconut trees with potassium (K) reduces (137)Cs concentration in drinking coconut meat at Bikini Atoll to about 5% of pretreatment concentrations. The magnitude of reduction is dependent on the concentration of (137)Cs in soil, and thereby in food crops, and is less for Enjebi and Rongelap Islands than for Bikini Island. Treatment of food crops and fruit trees with K and removal of the top 15 cm of soil around houses and community buildings prior to construction to reduce external exposure where people spend most of their time has been presented to the communities as a "Combined Option" remediation strategy. Doses presented here are calculated using the Combined Option, effective half-life of (137)Cs at the atolls, and a diet of both imported and local foods. The average natural background dose in the Marshall Islands, plus the anthropogenic nuclear test-related dose at Bikini, Enjebi, and Rongelap Islands, is less for each of the islands than the average background dose in the U.S. and Europe.

This article demonstrates the model's simplicity through an implementation within a heavily regulated research institution. The model utilizes control banding strategies with a stratification of four risk levels (RLs) for many commonly performed maintenance and support activities, characterizing risk consistently for comparable tasks. RLBMS creates an auditable tracking of activities, maximizes OSHH professional field time, and standardizes documentation and control commensurate to a given task's RL. Validation of RLs and their exposure control effectiveness is collected in a traditional quantitative collection regime for regulatory auditing. However, qualitative risk assessment methods are also used within this validation process. Participatory approaches are used throughout the RLBMS process. Workers are involved in all phases of building, maintaining, and improving this model. This worker participation also improves the implementation of established controls.

We report here on the longitudinal and individual variation in human plasma characterized by two-dimensional difference gel electrophoresis (2-D DIGE) using plasma samples from eleven healthy subjects collected three times over a two week period. Fixed-effects modeling was used to remove dye and gel variability. Mixed-effects modeling was then used to quantitate the sources of proteomic variation. The subject-to-subject variation represented the largest variance component, while the time-within-subject variation was comparable to the experimental variation found in a previous technical variability study where one human plasma sample was processed eight times in parallel and each was then analyzed by 2-D DIGE in triplicate. Here, 21 protein spots had larger than 50% CV, suggesting that these proteins may not be appropriate as biomarkers and should be carefully scrutinized in future studies. Seventy-eight protein spots showing differential protein levels between different individuals or individual collections were identified by mass spectrometry and further characterized using hierarchical clustering. The results present a first step toward understanding the complexity of longitudinal and individual variation in the human plasma proteome, and provide a baseline for improved biomarker discovery.

However, evidence for the presence of the Younger Dryas in the Gulf of Mexico (GOM) and the relationship between GOM sea surface temperature (SST) and high-latitude climate change is less clear. We present new Mg/Ca-SST records from two varieties of the planktonic foraminifer Globigerinoides ruber (white and pink) to assess northern GOM SST history from approximately 18.4-10.8 ka. Thirty-five accelerator mass spectrometry (AMS) (super 14) C dates from Orca Basin core MD02-2550 provide excellent age control and document high sedimentation rates ( approximately 40 cm/kyr). G. ruber (white and pink) Mg/Ca-SST data exhibit increases ( approximately 4.6 + or - 0.6 degrees C and approximately 2.2 + or - 0.5 degrees C, respectively) from at least 17.8-16.6 ka, with nearly decadal resolution that are early relative to the onset of the Bolling-Allerod interstadial. Moreover, G. ruber (white) SST decreases at 16.0-14.7 ka ( approximately 1.0 + or - 0.5 degrees C) and 12.8-11.6 ka ( approximately 2.4 + or - 0.6 degrees C) correlate to the Oldest and Younger Dryas in Greenland and Cariaco Basin. The G. ruber (pink) SST record, which reflects differences in seasonality and/or depth habitat, is often not in phase with G. ruber (white) and closely resembles Antarctic air temperature records. Overall, it appears that Orca Basin SST records follow Antarctic air temperature early in the deglacial sequence and exhibit enhanced seasonality during Greenland stadials.

Measures were taken to control and assess potential organic (and other) contaminants during the design, construction, and flight of the spacecraft, and during and after recovery of the sample return capsule. Studies of controls and the returned samples suggest that many of these potential sources did not contribute any significant material to the collectors. In particular, contamination from soils at the recovery site and materials associated with the ablation of the heatshield do not appear to be significant problems. The largest source of concern is associated with the C present in the original aerogel. The relative abundance of this carbon can vary between aerogel tiles and even within individual tiles. This C was fortunately not distributed among a complex mixture of organics, but was instead largely present in a few simple forms (mostly as Si-CH3 groups). In most cases, the signature of returned cometary organics can be readily distinguished from contaminants through their different compositions, nonterrestrial isotopic ratios, and/or association with other cometary materials.

The LLNL was established in 1952 at the height of the Cold War to meet urgent national security needs. As such, LLNL has a long history of carrying out research and development involving the use of the fissionable materials. Criticality safety (CS) was recognized very early as a key safety aspect in transporting, handling, and storage of fissionable materials. It should be noted, however, criticality safety was not a well-defined technical discipline in those early years. Thus, the development of criticality safety in general, and the evolution of the Criticality Safety Advisory Committee at LLNL, should be of historical and practical interests to the nuclear criticality safety community.

We identify three sources that contribute to groundwater flow: (1) seasonal groundwater recharge with short travel times, (2) water with elevated radiogenic (super 4) He that has experienced longer flow paths, and (3) upwelling of deep fluids that have "magmatic" helium and carbon isotope signatures. Results from our study illuminate two important aspects of the hydrological system that will have a direct impact on how this system responds to climate change: (1) recharge to the alluvial aquifer occurs primarily on the lower slopes of the catchment and is therefore sensitive to changes in snowline elevation and (2) deep groundwater in the western part of the aquifer is very young and provides very little buffering capacity. Although apparent groundwater ages indicate residence times range from less than a year to several decades, the water that recharges seasonally dominates the alluvial aquifer. Noble gas recharge temperatures are close to mean annual air temperature, and are 5 degrees -11 degrees higher than would be expected for direct influx of snowmelt. Excess air concentrations, indicating entrapment of air bubbles during recharge, are lower than would be expected for recharge through bedrock fractures. Instead, recharge likely occurs over vegetated areas on the lower slopes, as indicated by delta (super 13) C-dissolved inorganic carbon values that are consistent with incorporation of CO (sub 2) from soil respiration.

The seasonal context for such mean state changes is important for determining the mechanisms involved. We reconstructed surface ocean conditions in southwest Puerto Rico at approximately monthly resolution over eight 4-12 year periods during the last approximately 520 years to test if the seasonal cycles of temperature or salinity varied with mean state. We carried out paired analyses of Sr/Ca and delta (super 18) O for two coral cores. The delta (super 18) O data contained clear annual cycles and were significantly correlated to temperature during the 20th century calibration periods (1993-2004 and 1902-1912, r = 0.73). The Sr/Ca data contained high-frequency noise that obscured the seasonal cycles, although the centennial variability matched that of the coral delta (super 18) O, indicating a common forcing that is likely temperature. The seasonal coral delta (super 18) O amplitude averaged 0.60 + or - 0.17ppm, with none of the periods significantly different from the most recent. The simplest explanation is that the amplitudes of seasonal seawater delta (super 18) O and temperature variations were not different from today. Previous work in the southern Caribbean indicates that the Intertropical Convergence Zone was shifted southward or weaker during the Little Ice Age, and we speculate about how this could occur with no apparent affect on seasonality in the northern Caribbean.

The goals of these catheter-delivered devices include re-establishing blood flow in occluded arteries and preventing aneurysm rupture. Because these devices alter the hemodynamics and dissipate thermal energy during the therapeutic procedure, a first step in the device development process is to investigate fluid velocity and temperature changes following device deployment. A laser-heated SMP foam device was deployed in a simplified in vitro vascular model. Magnetic resonance imaging (MRI) techniques were used to assess the fluid dynamics and thermal changes associated with device deployment. Spatial maps of the steady-state fluid velocity and temperature change inside and outside the laser-heated SMP foam device were acquired. Though non-physiological conditions were used in this initial study, the utility of MRI in the development of a thermally-activated SMP foam device has been demonstrated.

Because U has separate production pathways than U, it can provide valuable information on the particular source of anthropogenic uranium in a sample. We demonstrated the utility of our improved capability by using U to distinguish separate sources of anthropogenic uranium in a set of samples collected from a contaminated site. In the future, we plan to apply our new capability to characterizing U in a wide range of uranium materials.

The primary source of contamination on Runit Island was the 1958 Quince safety test where a large quantity of device plutonium (Pu) was scattered over the area near the GZ. A second low-yield device was detonated on the same site 10 days later, further disturbing the soil and leaving behind a very heterogeneous pattern of contamination including milligram-size particles of plutonium. A limited cleanup of the Fig-Quince zone was carried out in 1979. During this period, the effectiveness of the cleanup operations was primarily evaluated on the basis of bulk soil concentration data with little consideration given to the heterogeneity and long-term material-, biological-, and environmental-specific impacts of residual high activity (hot) particle contamination. The aim of the present study was twofold; (i) to characterize the levels and distribution of residual contamination in the Fig-Quince zone, and (ii) to develop pertinent data on the frequency distribution, elemental and isotopic composition, and physico-chemical properties of hot particles isolated from surface soils from Fig-Quince with a view towards providing recommendations on the future management and possible cleanup of the site. Today, Runit Island remains under an administrative quarantine.

The detectors offer an energy resolution below 100 eV FWHM at 100 keV, and can therefore significantly increase the precision of NDA at low energies where line overlap affects the errors of the measurement when using germanium detectors. They also increase the peak-to-background ratio and thus improve the detection limits for weak gamma emissions from the fissile Pu and U isotopes at low energy in the presence of an intense Compton background from the fission products in spent fuel. Here we demonstrate high energy resolution and high peak-to-background ratio of our superconducting Gamma detectors, and discuss their relevance for measuring actinides in spent nuclear fuel.

The objective was to determine how differences in silicate liquid structure, such as the ratio of bridging to non-bridging oxygen atoms, as well as bulk transport properties such as viscosity, relate to isotope discrimination during diffusion. This information, in turn, may relate to the lifetimes and sizes of multi-atom structures in the liquid. Diffusion couples consisting of juxtaposed natural mafic and felsic liquids were held at T=1450 degrees C and P=1.0 GPa for durations of 12-24 h in a standard piston-cylinder assembly. Experiments were done using different mafic endmember compositions (two tholeiitic basalts and a ugandite) and a single rhyolite composition. Major-element diffusion profiles and Ca isotope profiles were measured on the recovered quenched glasses. The starting materials were isotopically indistinguishable, but (super 44) Ca/ (super 40) Ca variations of ca. 5 ppm arose due to a mass dependence of the Ca diffusion coefficients. Results indicate that the mass dependence of Ca diffusion coefficients varies with the magnitude and direction of aluminum gradients and the viscosity of the liquid. Some Ca fractionations result mainly from Al gradients. A simplified multicomponent diffusion model was used to model the experimental results. The model allows for diffusion of Ca in response to gradients in the concentrations of both CaO as well as Al (sub 2) O (sub 3) , and the model results are consistent with the inferred existence of at least two distinct species of Ca. The magnitude of isotopic discrimination during diffusion also appears to be stronger on the rhyolite versus the basalt/ugandite side of diffusion couples. The results can largely be accounted for by an adaptation of the model of Dingwell (1990), whereby in high silica liquids, Ca diffuses largely by site hopping through a quasi-stationary aluminosilicate matrix, producing strong isotopic effects because the Ca diffusion is not strongly correlated with the movement of the framework atoms. In low-silica liquids, Ca diffusion is correlated with the movement of the other components and there is less mass discrimination. Combining our Ca results with Ca, Mg, and Li data from previous studies, we show that this model can explain most of the cation- and composition-dependence of diffusive isotopic fractionations observed thus far. A key parameter controlling isotopic discrimination is the ratio of the elemental (Ca, Mg, Li) diffusivity to the Eyring (or Si) diffusivity. However, all experiments done so far also exhibit isotopic features that are not yet fully explained; some of these may relate to small temperature gradients in the capsules, or to more complex coupling effects that are not captured in simplified diffusion models.

The Quaternary sedimentary deposits of this basin are mainly endoreic lacustrine carbonate and alluvial deposits, developed in a semi-arid climate (Pleistocene-present). The basin is a NW-SE-elongated graben bounded by a major right-lateral oblique-fault, the Pozohondo Fault. This fault trends NW-SE, with an approximate trace of 55 km, and is composed of various segments which are identified by fault scarps. In order to establish the slip-rate of the most active segment of the Pozohondo Fault, called the Cordovilla segment, we carried out a detailed study of the affected Quaternary lacustrine deposits. We found that the lacustrine facies could be related to episodic moderate paleoearthquakes. The slip-rate is calculated to be 0.05 and 0.09 mm/yr, using radiometric dating for the vertical offsets of the lacustrine facies. A trenching study at the northern part of the Cordovilla segment revealed two events caused by paleoearthquakes, with the most recent expressed as an oblique-fault off-setting a poorly-developed soil. The magnitude of the last event was greater than 6, using various empirical relationships for the fault displacement and the surface-length rupture. We estimate episodic activity across the Cordovilla segment, to be characterized by moderate-sized paleoearthquakes (M6), which is in agreement with the tectonic context of an intraplate zone of the Iberian plate.

Wadati diagrams are plots of S-P vs P-wave travel-times and they are expected to lie along a straight line for a medium of constant velocity. Our procedure automatically searches for the largest subset of (P,S-P) travel-time pairs with regression coefficient above 0.9, which effectively removes travel-times associated with non-homogeneous ray-paths. Inaccuracies in travel-time picks due to clock drifts or complex arrivals and/or erroneous event associations are also identified and eliminated through this procedure. An application to P- and S-wave travel-times from 11,224 events recorded during 2007 on an in-mine network in Savuka mine near Carletonville (South Africa), reveals that a high correlation coefficient alone is not sufficient to ensure consistency. The histogram of v (sub p) /v (sub s) values inferred from the slopes of the Wadati diagrams peaks at values of 1.62 to 1.63, in agreement with the underlying geology, but a significant portion of the catalogued events show unrealistic v (sub p) /v (sub s) values. Adding realistic constraints on the slopes of the linear fits to the Wadati filter is critical to ensure the consistency of the travel-time picks. Event relocations obtained for the filtered data set assuming propagation at constant wave-speed do not deviate significantly from locations reported by the in-mine network operator.

Inti fassaite (Ca(Mg,Ti,Al)(Si,Al) (sub 2) O (sub 6) ) was found to have a Ti (super 3+) /Ti (super 4+) ratio of 2.0+ or -0.2, consistent with fassaite in other solar system CAIs. The oxygen fugacity (logf (sub O2) ) of formation estimated from this ratio, assuming equilibration among phases at 1509K, is -19.4+ or -1.3. This value is near the canonical solar nebula value (-18.1+ or -0.3) and in close agreement with that reported for fassaite-bearing Allende CAIs (-19.8+ or -0.9) by other researchers using the same assumptions. Nanocrystals of osbornite (Ti(V)N), 2-40nm in diameter, are embedded as inclusions within gehlenite, spinel and diopside in Inti. Vanadium is heterogeneously distributed within some osbornite crystals. Compositions range from pure TiN to Ti (sub 0.36) V (sub 0.64) N. The possible presence of oxide and carbide in solid solution with the osbornite was evaluated. The osbornite may contain O, but C is not present at detectable levels. The presence of osbornite, likely a refractory early condensate, together with the other refractory minerals in Inti, indicates that the parent comet contains solids that condensed closer to the proto-sun than the distance at which the parent comet itself accreted. The estimated oxygen fugacity and the reported isotopic and chemical compositions are consistent with Inti originating in the inner solar system like other meteoritic CAIs. These results provide insight for evaluating the validity of models of radial mass transport dynamics in the early solar system. The oxidation environments inferred for the Inti mineral assemblage are inconsistent with an X-wind formation scenario. In contrast, radial mixing models that allow accretion of components from different heliocentric distances can satisfy the observations from the cometary CAI Inti.

Differences in the geometrical spreading, source term, site term, and travel paths are accounted for, while event source parameters such as seismic moment are consistent among phases. In the process, we have developed the first comprehensive regional P-wave and S-wave attenuation model of the crust and upper mantle by simultaneously using the amplitudes of four regional phases. When applied to an area encompassing the Middle East, eastern Europe, western Asia, south Asia, and northeast Africa for the 1-2 Hz passband, we find large differences in the attenuation of the lithosphere across the region. The tectonic Tethys collision zone has high attenuation, while stable outlying regions have low attenuation. While crust and mantle Q variations are often consistent, we do find several notable areas where they differ considerably but are appropriate given the region's tectonic history. Lastly, the relative values of Qp and Qs indicate that scattering Q is likely the dominant source of attenuation in the crust at these frequencies.

Although F. tularensis has an extremely broad host range, the bacterial reservoir in nature has not been conclusively identified. In this study, the ability of virulent F. tularensis strains to survive and replicate in the amoeba Acanthamoeba castellanii was explored. We observe that A. castellanii trophozoites rapidly encyst in response to F. tularensis infection and that this rapid encystment phenotype is caused by factor(s) secreted by amoebae and/or F. tularensis into the coculture medium. Further, our results indicate that in contrast to the live vaccine strain LVS, virulent strains of F. tularensis can survive in A. castellanii cysts for at least 3 weeks postinfection and that the induction of rapid amoeba encystment is essential for survival. In addition, our data indicate that pathogenic F. tularensis strains block lysosomal fusion in A. castellanii. Taken together, these data suggest that interactions between F. tularensis strains and amoebae may play a role in the environmental persistence of F. tularensis.

This work is similar in nature to that of Campbell and Shashkov [1]; however, our approach is based on a finite element discretization that is fundamentally different from the mimetic finite difference framework. The finite element point of view leads to novel insights as well as improved numerical results. We begin with a generalized tensor version of the von Neumann-Richtmyer artificial viscosity, then convert it to a variational formulation and apply a Galerkin discretization process using high order Gaussian quadrature to obtain a generalized nodal force term and corresponding zonal heating (or shock entropy) term. This technique is modular and is therefore suitable for coupling to a traditional staggered grid discretization of the momentum and energy conservation laws; however, we motivate the use of such finite element approaches for discretizing each term in the Euler equations. We review the key properties that any artificial viscosity must possess and use these to formulate specific constraints on the total artificial viscosity force term as well as the artificial viscosity coefficient. We also show, that under certain simplifying assumptions, the two-dimensional scheme from [1] can be viewed as an under-integrated version of our finite element method. This equivalence holds on general distorted quadrilateral grids. Finally, we present computational results on some standard shock hydro test problems, as well as some more challenging problems, indicating the advantages of the new approach with respect to symmetry preservation for shock wave propagation over general grids.

Textures were measured both in situ and ex situ with neutron, synchrotron X-ray and electron backscatter diffraction. The trigonal-hexagonal phase transformation does not change the orientation of c- and a-axes, but positive and negative rhombs become equal in the hexagonal beta -phase. In naturally deformed quartzites measured by neutron diffraction a perfect texture memory was observed, i.e. crystals returned to the same trigonal orientation they started from, with no evidence of twin boundaries. Samples measured by electron back-scattered diffraction on surfaces show considerable twinning and memory loss after the phase transformation. In experimentally deformed quartz rocks, where twinning was induced mechanically before heating, the orientation memory is lost. A mechanical model can explain the memory loss but so far it does not account for the persistence of the memory in quartzites. Stresses imposed by neighboring grains remain a likely cause of texture memory in this mineral with a very high elastic anisotropy. If stresses are imposed experimentally the internal stresses are released during the phase transformation and the material returns to its original state prior to deformation. Similarly, on surfaces there are no tractions and thus texture memory is partially lost.

The range trends nearly north-south with modern glaciers confined to peaks >4800 m a.s.l. Geomorphology and geochronology in the nearby Cordillera Blanca and Junin Plain reveal that the Peruvian Andes preserve a detailed record of tropical glaciation. Here, we use ASTER imagery, aerial photographs, and GPS to map and date glacial features in both the western and eastern drainages of the Cordillera Huayhuash. We have used in situ produced cosmogenic (super 10) Be concentrations in quartz bearing erratics on moraine crests and ice-polished bedrock surfaces to develop an exposure age chronology for Pleistocene glaciation within the range. We have also collected sediment cores from moraine-dammed lakes and bogs to provide limiting (super 14) C ages for glacial deposits. In contrast to the ranges to the north and south, most glacial features within the Cordillera Huayhuash are Lateglacial in age, however we have identified features with ages that span approximately 0.2 to approximately 38 ka with moraine sets marking the onset of glacier retreat at approximately 0.3 ka, approximately 9-10 ka, approximately 13-14 ka, approximately 20-22 ka, and >26 ka. The range displays a pronounced east-west variation in maximum down-valley distance from the headwall of moraine crests with considerably longer paleoglaciers in the eastern drainages. Importantly, Lateglacial paleoglaciers reached a terminal elevation of approximately 4000 m a.s.l. on both sides of the Cordillera Huayhuash; suggesting that temperature may have been a dominant factor in controlling the maximum glacier extent. We suggest that valley morphology, specifically valley slope, strongly influences down-valley distance to the maximum glacier extent and potential for moraine preservation. While regionally there is an extensive record of older (>50 ka) advances to the north (Cordillera Blanca) and to the south (Junin region), the apparent lack of old moraines in this locality may be explained by the confined morphology of the Cordillera Huayhuash valleys that has inhibited the preservation of older glacial geomorphic features.

Miller (University of Wisconsin-Madison) Martin Schulz (Lawrence Livermore National Laboratory) Papers Session Sustainability and Reliability Thursday, 11:00AM - 11:30AM Room PB251 Abstract: We present a scalable temporal order analysis technique that supports debugging of large scale applications by classifying MPI tasks based on their logical program execution order. Our approach combines static analysis techniques with dynamic analysis to determine this temporal order scalably. It uses scalable stack trace analysis techniques to guide selection of critical program execution points in anomalous application runs.

15243929 AB - Raman and infrared (IR) spectroscopy are two complementary vibrational spectroscopic techniques that have experienced a tremendous growth in their use in biological and biomedical research. This is, in large part, due to their unique capability of providing label-free intrinsic chemical information of living biological samples at tissue, cellular, or sub-cellular resolutions. This article reviews recent developments in applying these techniques for the characterization of stem cells. A discussion of the potential for these methods to address some of the major challenges in stem cell research is presented, as well as the technological and scientific advancements that are needed to progress the knowledge in the field.

The soil samples were spiked with U and Pu tracers, dissolved in minerals acids, and U and Pu isotopes isolated and purified on commercially available ion-exchange columns. The ion-exchange technique employed a TEVA column coupled to a UTEVA column. U and Pu isotope fractions were then further isolated using separate elution schemes, and the purified fractions containing U and Pu isotopes analyzed sequentially using multi-collector inductively coupled plasma mass spectrometer (MCICP-MS). High precision measurements of U/U, U/U, U/U, and Pu/Pu in soil samples were attained using the described methodology and instrumentation, and provide a basis for conducting more detailed assessments of the behavior and transfer of uranium and plutonium in the environment.

Etna Volcano; characteristics, variability and causality, and implications for their sources AN - 742926420; 2010-045360 AB - Almost 50,000 long period (LP) events were recorded at Mt. Etna from November 2003 to May 2006. We analysed these events, as well as very long period (VLP) events which were associated with some of them. During some intervals the spectral and wavefield features of LP events remained steady, with significant changes occurring between the intervals. Based on the times of the changes, we distinguish five different sub-periods. In particular, during sub-period III (June-November 2005) the wavefield at the stations nearest to the summit area was composed of P waves. Locations for 150 LP events occurring in sub-period III, determined using radial semblance, changed, at the same time as the events' spectral features changed. It was during this sub-period that many of the LP events were associated with VLP events. Based on similarity of the waveforms, we distinguished two families of VLP events, with gradually evolving waveforms. The two families are located in slightly different places, but near the sources of the LP events. The change between the families occurred at the same time as the spectra of the LP events changed. Finally the source of the VLP events was investigated by performing complete waveform moment tensor inversion of stacks of the two families. Synthetic Green's functions for the full moment tensor were calculated for a homogeneous half-space. For both families, the source region with the highest variance reduction lies approximately beneath the active craters, at 500 m below the altitudes of the stations. The solutions for both families are very similar with sources that are between 60 and 70% isotropic. Attempts to determine deviatoric moment tensors produced consistently poorer fits. The remaining energy is poorly constrained and is likely to be noise. In conclusion, these results highlight changes in the LP and VLP events at Mt. Etna over time, and the causal relationship between them.

2011-060240 AB - The Nevada Test Site (NTS) in southern Nevada was the location of 828 underground nuclear tests conducted between 1951 and 1992. The Underground Testing Area (UGTA) program led by the U.S. Department of Energy (DOE) is currently undertaking studies to understand the extent of groundwater contamination caused by radionuclides introduced into the subsurface by these tests. As part of these studies, natural variations in groundwater chemical and isotopic compositions are being used along with groundwater modeling to interpret the groundwater flow patterns and velocities in each of the major testing areas at the NTS. The geochemical studies have allowed aspects of the NTS flow system to be identified that would not be apparent from hydraulic data alone. The geochemical studies rely on the concept that variations in the groundwater chemical and isotopic compositions are compatible with some flow system interpretations but not with others. The chemical and isotopic species considered in the analyses typically include the stable isotopes of water ( (super 2) H and (super 18) O), major cations and anions, carbon isotopes ( (super 13) C and (super 14) C), chlorine-36 ( (super 36) Cl) and strontium-87 ( (super 87) Sr). The geochemical studies conducted thus far for the major testing areas each use a combination of graphical and geochemical inverse modeling approaches to explain the downgradient changes in groundwater composition as a function of groundwater mixing and water/rock interaction. The flow system interpretations permitted by the geochemical studies are evaluated in the context of prevailing hydraulic gradients, the overall hydrogeologic setting, and the long-term climatic history of the area to further evaluate their likelihood.

Currently, the lake spills at 2196 m, and the highest level from the last glacial cycle is 2155 m (current level is 1945 m). Further evidence of high lake levels during the last glacial cycle comes from the distribution of tufa towers and of deep lake sediments from the Wilson Creek Formation (WCF). Based on the mapped distribution of the WCF (Lajoie, 1968, UC Berkeley Ph.D.), the highest lake level of the last glacial cycle was attained during the deposition of volcanic ash package A (rhyolitic ashes 1, 3 and 4, and basaltic ash 2). The high lake levels during package A follow an anomalous dry period observed in the WCF stratigraphy between Ash 4 and Ash 5 (23.1 + or - 1.2 ka; Chen et al. 1996, Science). (super 40) Ar/ (super 39) Ar measurements of sanidine crystals from Ash 4 yield a minimum age population of 16.6 + or - 0.7 ka, thus constraining the beginning of the lake level rise during Package A. Package A is capped by a layer of lacustrine silt containing fans of thinolite crystals, which are pseudomorphs from the metastable cold water mineral ikaite. Six new (super 14) C measurements on thinolite crystals from the top of the WCF yield ages of approximately 10.5-10.7 (super 14) C kyr BP. This result is consistent with the estimated thinolite (super 14) C age of approximately 9.5 (super 14) C kyr BP based on plant macrofossils from a core in the western embayment (Davis, 1999, Quat. Res.), if the reservoir age was approximately 1 kyr in the lake as it is today. If WCF thinolite can be correlated to the thinolite found in the core, an extensive thinolite-forming event occurred during the Younger Dryas (11.5-12.9 ka). In addition to the stratigraphic occurrence of thinolite, numerous tufa mounds with this texture have also been documented at different elevations. To test if all the thinolite formed in the Mono Basin occurred during the Younger Dryas, we measured (super 14) C ages from two thinolitic tufa mounds. One mound (2081 m) from the NE Mono Basin yielded an age of 12.8 (super 14) C kyr BP. A second mound (1955 m) just east of Black Point contains 19 layers, which yielded (super 14) C ages indicating a long interval of tufa formation during much of the last glacial interval. If all the outcrops of thinolite were coeval, the thinolite (super 14) C ages may indicate potential complications, which need further study.

Boulder/bedrock pairs from three locations near Upernavik (72 degrees N) were sampled in a transect stretching from the sea to the present-day ice margin. Two low-elevation ( approximately 25 m a.s.l.) erratic boulders located 35 km apart have exposure ages of 11.1 and 12.5 ka, providing an estimated deglaciation age for central-western Greenland. Adjacent bedrock samples are discordant, having modeled exposure ages of 13.3 and 16.7 ka, respectively. It appears that low-elevation ice was not erosive enough to completely remove rock containing (super 10) Be accumulated during previous interglacial periods. One high-elevation ( approximately 1000 m a.s.l.) erratic boulder (43 ka) and a corresponding bedrock sample (80 ka) indicate that high-elevation ice during the latest Pleistocene glaciation was even less erosive and failed to remove cosmogenic (super 10) Be inherited from previous periods of exposure. One possible scenario is that warm-based, erosive ice existed in the valleys, while cold-based, less-erosive ice existed in the highlands. It is also possible that the ice grew thinner after 40 ka BP, exposing the high-elevation boulder we sampled. Analytic uncertainties of exposure ages are 2-4%. To determine the amount of inherited (super 10) Be in clasts carried by the Greenland Ice Sheet, icebound rocks were removed from the glacier margin near Kangerlussuaq (67 degrees N), Ilulissat (69 degrees N), and Upernavik (72 degrees N). These clasts were sourced up-ice of the present-day ice margin. So far, two clasts from each site (n = 6) have been analyzed for cosmogenic (super 10) Be; only one (from Kangerlussuaq) yielded a (super 10) Be concentration robustly above blank level, indicative of about 1 ka of surface exposure. We hypothesize that the ice sheet retreated or thinned enough during a previous interglacial period to expose this clast or its source outcrop to cosmic radiation, suggesting that the ice sheet was at some point smaller than it is at present.

Silt and sand were isolated from each sample and delta (super 18) O and delta D were measured in the melted ice. Meteoric (super 10) Be, high values of which indicate exposure to the atmosphere, was extracted from the sediment. Although the delta (super 18) O and delta D values are largely consistent with values found in Pleistocene age ice from the Summit and Dye 3 ice cores, in many samples the deuterium excess is lower than ice core values. Also, some samples (mostly at the northern two sites) are enriched in delta (super 18) O above ice core Pleistocene values. These results are consistent with an open-system regelation mechanism for the entrainment of the sediment in most of the samples, as this mechanism both enriches delta (super 18) O and reduces deuterium excess. Meteoric (super 10) Be was measured in concentrations of up to 2.1 X 10 (super 8) atoms/gram (n= 13 samples). The highest values were found at the northernmost site, with lower maximum values of 6.4 X 10 (super 7) and 6.7 X 10 (super 6) measured at the central and southern sites, respectively. Concentrations of (super 10) Be at the northern two sites are consistent with those found elsewhere in well-developed Holocene and Pleistocene soils. The entrained soils must therefore have experienced thousands of years of exposure during interglacial periods or are the remains of erosion-resistant Tertiary regolith. Low (super 10) Be concentrations characteristic of the southern site are consistent with amounts typically found in weathered bedrock below soil profiles, suggesting deep erosion after prior exposure. This latitudinal variation in (super 10) Be concentration is best explained by slower rates of erosion and/or longer sediment transport times at the northern field sites. Higher abundance of surface-melt-derived basal water at southern latitudes could explain the difference in sub-ice erosion rates, as such water can both scour subglacial sediments and create conditions for open-system regelation. The two highest (super 10) Be concentration samples from the northernmost field site lack a regelation enrichment stable isotope signature, suggesting that these samples were entrained where open system regelation was not active.

However because modern climate and ocean circulation records are relatively short, it is unclear if AMV noted in the 20 (super th) century is a persistent feature of the Atlantic climate system, if it is connected to MOC, and if the tropical Atlantic plays an active or passive role in the process. Isotopic and elemental ratio data from two continuous coral cores that grew offshore from Puerto Rico are used to reconstruct climate variability in the Caribbean region since the beginning of the Little Ice Age. New data include annually-resolved coral Sr/Ca and delta (super 18) O records spanning the years 1469 to 1669. Spectral analysis of data from both cores indicate a persistent approximately 60 year period signal that appears to be primarily temperature-related in the earlier part of the record but is associated with a shift in the trade winds and the regional salinity gradient over the period of overlap with the instrumental record. We find that the northern Caribbean was relatively cool during most of the Little Ice Age, with a approximately 2 degrees warming trend since about 1750, broadly consistent with other temperature reconstructions of this region. Oxygen isotope data from core sections sampled at monthly resolution show no significant change in the seasonal cycle over the significant shift in mean temperature. These new data demonstrate that AMV is a persistent feature of the modern tropical Atlantic Ocean, at least over the last 540 years, paving the way for more process-oriented studies on its relationship to MOC and global climate processes.

Here we report the effects of Fe (super 3+) and Al (super 3+) on Mg-silicate perovskite at high pressure. Perovskites with 0.09Fe (sub 2) O (sub 3) . 0.91MgSiO (sub 3) and 0.05Fe (sub 2) O (sub 3) . 0.05Al (sub 2) O (sub 3) . 0.9MgSiO (sub 3) were synthesized above 50 GPa in the laser-heated diamond-cell. The spin state of Fe (super 3+) was determined by synchrotron Mossbauer spectroscopy and X-ray emission spectroscopy at high-pressure. The effect of trivalent cation substitution on the unit cell volume of perovskite was investigated using synchrotron X-ray diffraction. Above 50 GPa, Fe (super 3+) and Al (super 3+) enter the perovskite structure primarily by charge-coupled substitution. When Fe (super 3+) exists alone in perovskite, it enters both the dodecahedral and octahedral sites. With compression, Fe (super 3+) in the octahedral site undergoes a gradual change to the low spin state, while Fe (super 3+) in the dodecahedral site remains high spin to at least 136 GPa. The spin transition results in a low bulk modulus for perovskite below 60 GPa. When Fe3+ exists together with Al, at low pressure the majority of Fe (super 3+) sits in the dodecahedral site in the high spin state. However, we found a rapid increase in the low spin Fe (super 3+) fraction in the octahedral site of perovskite at approximately 70 GPa. Because low spin Fe (super 3+) is similar in size to Al (super 3+) , more Fe (super 3+) enters the octahedral site at higher pressure, while Al (super 3+) must enter into the dodecahedral site. Above 80 GPa, approximately half of the Fe (super 3+) exists in the octahedral site. As a result of the site mixing, the Al-bearing perovskite has a significantly smaller volume at lowermost mantle pressures.

We have reacted the end member components the heterolithic sandstone and shale unit that forms the upper section of the carbon storage reservoir at the Krechba Field, In Salah, Algeria with supercritical CO (sub 2) and class G cement in a synthetic brine. One-dimensional reactive transport simulations of cement in contact with shale and sandstone suggest that diffusive transport of CO (sub 2) in the cement is limited by the reaction of calcium silica hydrates and portlandite to aragonite and amorphous silica. These reactions effectively buffer the CO (sub 2) -rich brine and limit enhanced porosity to a localized area in lower reaches of a hypothetical cement-cap rock fracture. The experimental results are consistent with preliminary simulations, but suggest that illite in the shale may be more reactive. Analysis of the solution chemistry over time and the solid products at the experiment end show that the well bore environment is dominated by reactions between cement and CO (sub 2) -rich fluids. Anhydrous calcium silicate cement phases fully reacted to amorphous silica, calcite, and aragonite in experiments with and without sandstone or shale. Sandstone integrity is retained, because quartz solubility and dissolution are minimal at acid pH in the CO (sub 2) -rich brines. Reaction of the shale is distinct from the reaction of the sandstone when directly exposed to the CO (sub 2) -rich brine and the cement. Although both surfaces show an accumulation of CaCO (sub 3) precipitates, there was no mass precipitation of the amorphous silica phase as was observed for the sandstone. Instead we see dissolution etch pits as well as the formation of a fibrous precipitate at the illite surface. Additionally, the evidence of brine in the shale interlayers suggests that permeability between shale layers should be included to appropriately model well-bore integrity between the cement and shale-rich layers at the Krechba Field.

In the BP, (super 10) Be ages are approximately 14-15 ka on four ignimbrite boulders, approximately 26 and approximately 20 ka on two quartz boulders, and approximately 45 ka on ignimbrite bedrock below the trimline in the valley wall. In the Eastern Cordillera bordering Lake Junin, the most extensive glaciations are >150 ka, but end moraine loops farther upvalley date to the local last glacial maximum (LLGM; approximately 26-30 ka) and a late-glacial stillstand or readvance ( approximately 14-18 ka). In NJR, (super 10) Be ages indicate that the largest lateral moraines were deposited during similar intervals: the LLGM ( approximately 27-32 ka) and late-glacial ( approximately 13-18 ka). Avulsion of a glacial valley preserved an older, smaller pair of lateral moraines (ca. 56-65 ka) in NJR; correlative moraines were apparently not preserved in the Junin valleys. We have found no moraines in NJR that date to the global LGM ( approximately 19-24 ka), but see some evidence for an advance approximately 40-48 ka. Three cobbles provide a minimum age of approximately 50 ka for lodgement till that extends approximately 6 km across the Conococha Plain beyond the termini of the NJR moraines. The wide distribution of till suggests that at least one older glaciation was far more extensive than any of the late Quaternary NJR advances that we have dated by (super 10) Be (ages calculated using CRONUS-Earth Online Calculator v. 2.2, Lal/Stone time-dependent scaling, and zero erosion). The timing of glacial advances in the central Peruvian Andes since 70 ka suggests a correlation to Heinrich events and associated southward shifts of the Intertropical Convergence Zone (ITCZ) in the Atlantic Ocean. We propose that Peruvian glaciers typically expanded when southward migration of the ITCZ resulted in increased precipitation in the tropical Andes during colder intervals.

As measurement capabilities improve and more sophisticated applications are developed, an accurate production rate estimate is critical for interpreting (super 10) Be measurements in terrestrial materials. A recent study by Balco et al. (2009, Quat. Geochron. 4, 93) suggests differences on the order of 10% between (super 10) Be production rate estimates from New England and more commonly used global values. The CRONUS-Earth project has been working to better characterize production rate systematics for all commonly measured TCNs. As part of this effort, we sampled a well-dated wave-cut quartzite shoreline bench associated with the high stand of Pleistocene Lake Bonneville (Bonneville level) at Promontory Point, Utah. The Bonneville shoreline formed during a period of overflow into southern Idaho, and was abandoned essentially instantaneously during the catastrophic Bonneville flood. The timing of shoreline formation is constrained by over 20 (super 14) C ages to between ca. 18.3 and 17.4 cal ka. Field and GIS analyses suggest that the sampling locations were covered by ca. 25 m of water during overflow, and that approximately 80-100 m of overburden was removed during formation of the ca. 300-m-wide bedrock bench. We take 17.4 + or - 0.2 cal ka as the exposure age for our samples, as no evidence of prior occupation of this shoreline level has been recognized. Samples were thoroughly homogenized, and aliquots distributed to four laboratories for (super 10) Be processing. Aliquots from three labs were analyzed for (super 10) Be at LLNL-CAMS, while the fourth was analyzed at PRIME Lab. The mean (super 10) Be concentration at the site is (2.54 + or - 0.10) X 10 (super 5) at g (super -1) (07KNSTD, n=24), yielding a site production rate of approximately 14.7 + or - 0.6 (super 10) Be at g (super -1) a (super -1) . Corresponding sea level, high latitude (SLHL) production rates were calculated with a chi-squared minimization routine, using algorithms and assumptions from the CRONUS Online Calculator (Balco et al., 2008, Quat. Geochron. 3, 174). These SLHL values (4.2 to 4.7 at g (super -1) a (super -1) , depending on scaling model) are consistent with those of Balco et al. (2009) and the previous global estimates, but with lower scatter (< 4% 1sigma ).

In seismically active regions, PBRs effectively act as seismoscopes in residence for thousands of years, constraining the ground motions that have occurred during this time period (the PBR age). Thus, the age of PBRs and their rate of renewal through exhumation are important for validating seismic hazard models and understanding rates of soil formation and landscape evolution in tectonically active regions. Cosmogenic radionuclide (CRN) surface exposure dating can be applied to constrain the age of formation of PBRs, but to interpret nuclide abundance requires knowledge of the geomorphic history of the rock. Initial efforts by Bell et al. (1998) indicated that rocks were precariously balanced for greater than 10,000 years in southern California. In a pilot study, we collected 10 samples from 6 PBRs at four sites spanning a 110-km section of the San Andreas Fault for CRN exposure dating using (super 10) Be. Pedestal samples consistently yielded younger apparent ages than the associated PBR, indicating that exhumation history is important in developing exposure ages. Preliminary exposure times ("PBR ages") assuming a fast exhumation model and simplified shielding corrections range from 16 kyr to 23 kyr, suggesting that formation of PBRs in Southern California is linked to late Pleistocene pluvial conditions at the end of the last glacial, or climate change and exhumation by rapid erosion at the late Pleistocene/Holocene transition.

Our numerical approach includes a fluid mechanical model that is a combination of a compressible code (GEODYN) and a low Mach code (LMC). Early stages of nuclear explosions that are characterized by the blust wave propagation are simulated with an explicit code (GEODYN) that solves the compressible Navier-Stokes equations via a high-order Godunov scheme. As soon as the blust wave weakens (~10s) the subsequent cloud rise due to buoyancy forces can be effectively simulated by the LMC code. LMC is an implicit code based on a pressure projection technique, and derived from the compressible Navier-Stokes equations using an asymptotic analysis in Mach number. It analytically eliminates time step restrictions based on sound wave propagation and it is computationally efficient and accurate for simulations of cloud rise dynamics at later stages. We perform a series of cloud rise scenarios ranging from an idealized bubble rise problem to realistic air bursts. We analyze effects of compressible dynamics on cloud evolution at different stages. It is found that in a realistic configuration, interaction of the reflected shock wave from the ground with the fireball significantly affects cloud evolution, in contrast to the equivalent idealized bubble rise simulations. We validate the code predictions against available experimental data. It is demonstrated that, by providing the initial source from the compressible GEODYN code, late time flow evolution can be successfully simulated with the fast, efficient and accurate LMC code.

Despite their importance in paleoclimate research, few studies have investigated the relationship between NGT and actual recharge temperatures in field settings. This study presents dissolved noble gas data from a shallow unconfined aquifer heavily impacted by agriculture. Considering samples unaffected by degassing, NGT calculated from common physically based interpretive gas dissolution models that correct measured noble gas concentrations for "excess air" agreed with measured water table temperatures (WTT). The ability to fit data to multiple interpretive models indicates that model goodness-of-fit does not necessarily mean that the model reflects actual gas dissolution processes. Although NGT are useful in that they reflect WTT, caution is recommended when using these interpretive models. There was no measurable difference in excess air characteristics (amount and degree of fractionation) between two recharge regimes studied (higher flux recharge primarily during spring and summer vs. continuous, low flux recharge). Approximately 20% of samples had dissolved gas concentrations below equilibrium concentration with respect to atmospheric pressure, indicating degassing. Geochemical and dissolved gas data indicate that saturated zone denitrification caused degassing by gas stripping. Modeling indicates that minor degassing (<10% Delta Ne) may cause underestimation of ground water recharge temperature by up to 2 degrees C. Such errors are problematic because degassing may not be apparent and degassed samples may be fit by a model with a high degree of certainty.

Two additional CAIs were measured for oxygen isotopes only. Most CR2 CAIs are mineralogically pristine; only few contain secondary phyllosilicates, sodalite, and carbonates - most likely products of aqueous alteration on the CR2 chondrite parent asteroid. Spinel, hibonite, grossite, anorthite, and melilite in 18 CAIs have (super 16) O-rich (Delta (super 17) O=-23.3+ or -1.9 ppm, 2sigma error) compositions and show no evidence for postcrystallization isotopic exchange commonly observed in CAIs from metamorphosed CV carbonaceous chondrites. The inferred initial (super 26) Al/ (super 27) Al ratios, ( (super 26) Al/ (super 27) Al) (sub 0) , in 15 of 16 (super 16) O-rich CAIs measured are consistent with the canonical value of (4.5-5)X10 (super -5) and a short duration (-5 ppm) nebular gas. The low inferred ( (super 26) Al/ (super 27) Al) (sub 0) ratios of these CAIs (2My after crystallization of CAIs with the canonical ( (super 26) Al/ (super 27) Al) (sub 0) and suggest evolution of the oxygen-isotope composition of the inner solar nebula on a similar or a shorter timescale. Because CAIs in CR2 and CV chondrites appear to have originated in a similarly (super 16) O-rich reservoir and only a small number of CR2 and CV CAIs were affected by chondrule melting events in an (super 16) O-poor gaseous reservoir, the commonly observed oxygen-isotope heterogeneity in CAIs from metamorphosed CV chondrites is most likely due to fluid-solid isotope exchange on the CV asteroidal body rather than gas-melt exchange. This conclusion does not preclude that some CV CAIs experienced oxygen-isotope exchange during remelting, instead it implies that such remelting is unlikely to be the dominant process responsible for oxygen-isotope heterogeneity in CV CAIs. The mineralogy, oxygen and magnesium-isotope compositions of CAIs in CR2 chondrites are different from those in the metal-rich, CH and CB carbonaceous chondrites, providing no justification for grouping CR, CH and CB chondrites into the CR clan.

Data for seven additional chondrules from three CV and two CR chondrites show evidence suggestive of the presence of (super 26) Al but do not yield well defined values for ( (super 26) Al/ (super 27) Al) (sub 0) , while the remaining chondrules do not contain excess radiogenic (super 26) Mg and yield corresponding upper limits of (11-2)X10 (super -6) for ( (super 26) Al/ (super 27) Al) (sub 0) . The observed range of ( (super 26) Al/ (super 27) Al) (sub 0) in PRCs from CCs is similar to the range seen in chondrules from unequilibrated ordinary chondrites (UOCs) of low metamorphic grade (3.0-3.4). However, unlike the UOC chondrules, there is no clear trend between the ( (super 26) Al/ (super 27) Al) (sub 0) values in PRCs from CCs and the degree of thermal metamorphism experienced by the host meteorites. High and low values of ( (super 26) Al/ (super 27) Al) (sub 0) are found equally in PRCs from both CCs lacking evidence for thermal metamorphism (e.g., CRs) and CCs where such evidence is abundant (e.g., CVs). The lower ( (super 26) Al/ (super 27) Al) (sub 0) values in PRCs from CCs, relative to most CAIs, are consistent with a model in which (super 26) Al was distributed uniformly in the nebula when chondrule formation began, approximately a million years after the formation of the majority of CAIs. The observed range of ( (super 26) Al/ (super 27) Al) (sub 0) values in PRCs from CCs is most plausibly explained in terms of an extended duration of approximately 2-3 Ma for the formation of CC chondrules. This interval is in sharp contrast to most CAIs from CCs, whose formation appears to be restricted to a narrow time interval of less than 10 (super 5) years. The active solar nebula appears to have persisted for a period approaching 4 Ma, encompassing the formation of both CAIs and chondrules present in CCs, and raising important issues related to the storage, assimilation and mixing of chondrules and CAIs in the early solar system.

The data reviewed are consistent with an external, stellar origin for most short-lived radionuclides ( (super 7) Be, (super 10) Be, and (super 36) Cl are important exceptions) and a shock-wave model for chondrule formation, and provide a sound basis for early Solar System chronology. They are inconsistent with the x-wind model for the origin of chondritic components and a local, irradiation origin of (super 26) Al, (super 41) Ca, and (super 53) Mn. (super 10) Be is heterogeneously distributed among CAIs, indicating its formation by local irradiation and precluding its use for the early solar system chronology. (super 41) Ca- (super 41) K, and (super 60) Fe- (super 60) Ni systematics are important for understanding the astrophysical setting of Solar System formation and origin of short-lived radionuclides, but so far have limited implications for the chronology of chondritic components. The chronological significance of oxygen-isotope compositions of chondritic components is limited. The following general picture of formation of chondritic components is inferred. CAIs and AOAs were the first solids formed in the solar nebula approximately 4567-4568 Myr ago, possibly within a period of -10 ppm) and have ( (super 26) Al/ (super 27) Al) (sub 0) similar to those in chondrules (-5 ppm) nebular gas. The majority of chondrules within a chondrite group may have formed over a much shorter period of time (<0.5-1 Myr). Mineralogical and isotopic observations indicate that CAIs were present in the regions where chondrules formed and accreted (1-4 AU), indicating that CAIs were present in the disk as free-floating objects for at least 4 Myr. Many CAIs, however, were largely unaffected by chondrule melting, suggesting that chondrule-forming events experienced by a nebular region could have been small in scale and limited in number. Chondrules and metal grains in CB chondrites formed during a single-stage, highly-energetic event approximately 4563 Myr ago, possibly from a gas-melt plume produced by collision between planetary embryos.

The sites represent Douglas-fir forest ecosystems at two contrasting successional stages: old-growth (OG) and early seral (ES). Here we present eddy flux and meteorological data from two early seral stands and the Wind River AmeriFlux old-growth forest during the growing season (March-October) in 2006 and 2007. We show an alternative approach to the usual friction velocity (u sub(*)) method for determining periods of adequate atmospheric boundary layer mixing based on the ratio of mean horizontal (U) or vertical (w?) wind flow to a modified turbulent kinetic energy scale (u sub(T) sub(K) sub(E)). This new parameter in addition to footprint modeling showed that daytime CO sub(2) fluxes (F sub(N) sub(E) sub(E)) in small clear-cuts (<10ha) can be measured accurately with EC if micrometeorological conditions are carefully evaluated. Peak midday CO sub(2) fluxes (F sub(N) sub(E) sub(E)=-14.0 to -12.3kmolm super(-) super(2)s super(-) super(1)) at OG were measured in April in both 2006 and 2007 before bud break when air and soil temperatures and vapor pressure deficit were relatively low, and soil moisture and light levels were favorable for photosynthesis. At the early seral stands, peak midday CO sub(2) fluxes (F sub(N) sub(E) sub(E)=-11.0 to -8.7kmolm super(-) super(2)s super(-) super(1)) were measured in June and July while spring-time CO sub(2) fluxes were much smaller (F sub(N) sub(E) sub(E)=-3.8 to -3.6kmolm super(-) super(2)s super(-) super(1)). Overall, we measured lower evapotranspiration (OG=230mm, ES=297mm), higher midday F sub(N) sub(E) sub(E) (OG F sub(N) sub(E) sub(E)=-9.0kmolm super(-) super(2)s super(-) super(1), ES F sub(N) sub(E) sub(E)=-7.3kmolm super(-) super(2)s super(-) super(1)) and higher Bowen ratios (OG b=2.0, ES b=1.2) at the old-growth forest than at the ES sites during the summer months (May-August). Eddy covariance studies such as ours add critical land-atmosphere exchange data for an abundant, but rarely studied Douglas-fir age class.

Peat cores were collected in remnant and drained marshes in the Sacramento-San Joaquin Delta of California. Cubic smooth spline regression models were used to construct age-depth models and accretion histories for three remnant marshes. Estimated vertical accretion rates at these sites range from 0.03 to 0.49 cm year (super -1) . The mean contribution of organic matter to soil volume at the remnant marsh sites is generally stable (4.73% to 6.94%), whereas the mean contribution of inorganic matter to soil volume has greater temporal variability (1.40% to 7.92%). The hydrogeomorphic position of each marsh largely determines the inorganic content of peat.

The computed IR spectra and structure of the uranyl-protein complex facilitate interpretation of the observed spectra and confirm the primary binding sites of the transferrin protein with the uranyl ion. Our computed equilibrium geometry and the IR spectra of the uranyl-TF complex reveal that uranyl ion is bound to two tyrosines, one aspartate group, and one carbonate ion. Our IR spectra indicate that histidine is not involved in binding to uranyl with transferrin protein. Our computations reveal a short, strong hydrogen bond, which could play an important role in the stabilization and formation of the uranyl-TF complex. Computed Laplacian charge plots indicate high chemical reactivity on this complex as both an electrophile and a nucleophile, facilitating binding to different receptors and thus entry into a number of target organs and the blood-brain barrier. The Mulliken charge density plots and the three-dimensional charge density plots suggest a donor-acceptor mechanism in the complex formation.

In 1965, a unique, sixteen year pumping experiment designed to examine radionuclide migration away from the CAMBRIC nuclear test, conducted in the saturated zone beneath Frenchman Flat, Nevada, USA, gave rise to an unintended second experiment involving radionuclide infiltration through the vadose zone, as induced by seepage of pumping effluents beneath an unlined discharge trench. The combined experiments have been reanalyzed using a detailed, three-dimensional numerical model of transient, variably saturated flow and mass transport in a heterogeneous subsurface, tailored specifically for large-scale and efficient calculations. Simulations have been used to estimate tritium travel and residence times in various parts of the system for comparison with observations in wells. Model predictions of mass transport were able to clearly demonstrate radionuclide recycling behavior between the trench and pumping well previously suggested by isotopic age dating information; match travel time estimates for radionuclides moving between the trench, the water table, and monitoring and pumping wells; and provide more realistic ways in which to interpret the pumping well elution curves. Collectively, the results illustrate the utility of integrating detailed numerical modeling with diverse observational data in developing more accurate interpretations of contaminant migration processes.

Since 6000 cal yr B.P., sediment carbonate abundance has followed a decreasing trend while organic-carbon abundance has increased. The correlation between organic-carbon abundance and the sum of March-April-October-November insolation has an r (super 2) value of 0.58. We interpret these trends to represent a precession-driven lengthening of the Holocene growing season that has reduced calcite burial by enhancing net annual organic-matter production and associated calcite dissolution. Correlations with regional paleoclimate records suggest that changes in temperature and moisture balance have impacted the distribution of short-term oscillations in carbonate and organic-matter abundance superimposed on the precession-driven trends.

All IDPs have isotopic compositions tightly clustered around that of solar system planetary materials. Hydrated IDPs have mass-fractionated oxygen isotopic compositions similar to those of CI and CM carbonaceous chondrites, consistent with hydration of initially anhydrous protosolar dust. Anhydrous IDPs have small (super 16) O excesses and depletions similar to those of carbonaceous chondrites, the largest (super 16) O variations being hosted by the two GEMS-rich IDPs. Coarse-grained forsteritic olivine and enstatite in anhydrous IDPs are isotopically similar to their counterparts in comet Wild 2 and in chondrules suggesting a high temperature inner solar system origin. The small variations in the (super 16) O content of GEMS-rich IDPs suggest that most GEMS either do not preserve a record of interstellar processes or the initial interstellar dust is not (super 16) O-rich as expected by self-shielding models, although a larger dataset is required to verify these conclusions. Together with other chemical and mineralogical indicators, O isotopes show that the parent-bodies of carbonaceous chondrites, of chondritic IDPs, of most Antarctic micrometeorites, and comet Wild 2 belong to a single family of objects of carbonaceous chondrite chemical affinity as distinct from ordinary, enstatite, K- and R-chondrites.

Source identification is crucial to effective source mitigation; conversion of residential septic systems to sewer in a rural community will be ineffective if the primary source of nitrate contamination is agricultural operations. Determining the source of nitrate in an aquifer, however, can be difficult Nitrate occurs naturally and has a number of anthropogenic sources, including synthetic fertilizers, animal manure, septic systems, and municipal wastewater. More than one source may be present in a recharge area, and the sources may be diffuse, distributed, or localized. As a result, groundwater nitrate contamination is often widely distributed with limited concentration range, making traditional plume-tracking methods of placing wells upgradient and downgradient of a suspected source ineffective. Characterizing nitrate transport is also essential to effective management. Since nitrate travels without significant attenuation in oxygen-rich groundwaters, natural tracers of groundwater flow can help distinguish between ongoing and historic sources of nitrate, and can be used to identify appropriate wells for assessing the impact of land use or management changes on groundwater quality. The most significant process for degradation of nitrate in groundwater is denitrification, the microbial conversion of nitrate to nitrogen gas. Demonstrating that denitrification is occurring can lead to acceptance of monitored natural attenuation as a viable remediation plan, and can reconcile measured and modeled nitrate concentrations.

Geographical regions, latitude bands, and elevation classes where these trends are statistically significantly different from trends associated with natural climate variations are identified. Variables analyzed include late-winter and spring temperature, winter-total snowy days as a fraction of winter-total wet days, 1 April snow water equivalent (SWE) as a fraction of October-March (ONDJFM) precipitation total [precip(ONDJFM)], and seasonal [JFM] accumulated runoff as a fraction of water-year accumulated runoff. Observed changes were compared to natural internal climate variability simulated by an 850-yr control run of the finite volume version of the Community Climate System Model, version 3 (CCSM3-FV), statistically downscaled to a [imgchar=http://ams.allenpress.com/charent/iso_characters_mixed/lo w ercase/frac18.gif] grid using the method of constructed analogs. Both observed and downscaled model temperature and precipitation data were then used to drive the Variable Infiltration Capacity (VIC) hydrological model to obtain the hydrological variables analyzed in this study. Large trends (magnitudes found less than 5% of the time in the long control run) are common in the observations and occupy a substantial part (37%-42%) of the mountainous western United States. These trends are strongly related to the large-scale warming that appears over 89% of the domain. The strongest changes in the hydrologic variables, unlikely to be associated with natural variability alone, have occurred at medium elevations [750-2500 m for JFM runoff fractions and 500-3000 m for SWE/Precip(ONDJFM)] where warming has pushed temperatures from slightly below to slightly above freezing. Further analysis using the data on selected catchments indicates that hydroclimatic variables must have changed significantly (at 95% confidence level) over at least 45% of the total catchment area to achieve a detectable trend in measures accumulated to the catchment scale.

In-depth comparisons between modeled and observed regional-average precipitation, 2m temperature, and snowpack are performed. The regional model reproduces the spatial distribution of precipitation quite well, but substantially overestimates rainfall along windward slopes. This is due to strong overprediction of precipitation intensity; precipitation frequency is actually underpredicted by the model. Moisture fluxes impinging on the coast seem to be well-represented over California, implying that precipitation bias is caused by processes internal to WRF. Positive-definite moisture advection and use of the Grell cumulus parameterization result in some decrease in precipitation bias, but other sources are needed to explain the full bias magnitude. Surface temperature is well simulated in all seasons except summer, when overly-dry soil moisture results in a several degree warm bias in both CCSM3 and WRF. Additionally, coastal temperatures appear to be too warm due to a coastal sea surface temperature bias inherited from CCSM3. Modeled snowfall/snowmelt agrees quite well with observations, but snow water equivalent is found to be much too low due to monthly reinitialization of all regional model fields from CCSM3 values.

The transition occurs due to changes in the background plasma parameters. The Alfven speed eventually exceeds the shock speed; the shock does not run out of energy. At this velocity transition, the shock disassembles into two types of waves: the usual compressional Alfven wave and a left-hand polarized electromagnetic shear Alfven wave. This latter wave shows remarkable 3-D coherence, and preliminary analysis suggests that there are two possible sources of energy: one is coupling to the strong electromagnetic waves that exist within the collisionless shock and the other is the density and magnetic field gradients at the interface.

13713918 AB - The lunar meteorite Northwest Africa (NWA) 032 is a low-Ti basalt that has incompatible-element abundances and Th/Sm ratios characteristic of the involvement of late stage magma ocean crystallization products (urKREEP) in its petrogenesis. This sample is very fine-grained and contains terrestrial weather products. A progressive leaching procedure was therefore developed and applied to magnetic separates and whole rock fractions to obtain Rb-Sr and Sm-Nd ages. Although many of the leachates, as well as the unleached mineral and whole rock fractions contain terrestrial alteration products, selected residue fractions yield concordant Rb-Sr and Sm-Nd ages. Rubidium-Sr isotopic analyses yield an age of 2947 +/- 16 Ma with an initial super(87)Sr/ super(86)Sr of 0.700057 +/- 17. These characteristics indicate NWA 032 is derived from a source region with an super(87)Rb/ super(86)Sr ratio of 0.044 +/- 0.001. This value is higher than all but those determined for KREEP basalts, and suggests that NWA 032 is derived from a source region that has higher incompatible-element abundances than other low-Ti basalts. Samarium-neodymium isotopic analysis yield a concordant age of 2931 +/- 92 Ma and an initial e sub(Nd) of +9.71 +/- 0.74 corresponding to a source region with super(147)Sm/ super(144)Nd ratio of 0.246 +/- 0.004. The initial Nd isotopic composition stands in contrast to the initial Sr isotopic composition by requiring NWA 032 to be derived from a source with lower incompatible-element abundances than most low-Ti basalts. The source of NWA 032 is therefore unlike those of other lunar basalts. Modeling of magma ocean cumulate formation demonstrates that unlike other low-Ti basalt source regions the NWA 032 source is a mixture of olivine, pigeonite, and clinopyroxene bearing cumulates and only a small amount of urKREEP. Furthermore, unlike other mare basalt sources, the NWA 032 source does not contain appreciable quantities of plagioclase. Partial melting models demonstrate that the incompatible-element characteristics of the NWA 032 result from formation by smaller degrees of partial melting than other mare basalts. Thus, the incompatible-element geochemical signature that is observed in NWA 032 appears to reflect the combined effects of generation from an unusual plagioclase-free incompatible-element-depleted source region by very small degrees of partial melting. This study demonstrates that both the presence of urKREEP in the source region and small degrees of partial melting generate magmas with similar, but not identical, incompatible-element characteristics. In addition, it underscores the fact that there is significantly more geochemical diversity on the Moon than is represented by samples collected by the American and Soviet lunar missions.

Optical coherence tomography (OCT) is commonly used to image the 3D structure of the retina and while the added functionality of biochemical analysis afforded by Raman scattering could provide critical molecular signatures for clinicians and researchers, there are many technical challenges to combine these imaging modalities. We describe an OCT microscope for ex-vivo imaging combined with Raman spectroscopy capable of collecting morphological and molecular information about a sample simultaneously. We present our first results and discuss the challenges to further development of this dual-mode instrument and limitations for future in-vivo retinal imaging.

Commercial stents are generally made of stainless steel or other alloys. These alloys are too stiff and prevent most stent designs from being able to navigate small and tortuous vessels to reach intracranial lesions. A solid tubular model and a high flexibility laser etched model are presented. The stents were tested for collapse in a pressure chamber. At 37C, the full collapse pressure was comparable to that of commercially available stents, and higher than the estimated maximum pressure exerted by intracranial arteries. However, there is a potential for onset of collapse, which needs further study. The stents were crimped and expanded, the laser-etched stent showed full recovery with an expansion ratio of 2.7 and a 1% axial shortening.

10099356 AB - Large Type-I edge localized modes (ELMs) were suppressed by n = 3 resonant magnetic perturbations (RMPs) from a set of internal coils in plasmas with an ITER similar shape at the ITER pedestal collisionality, [MathML equation] and low edge safety factor (q sub(95) [asymptotic to] 3.6), with either a single toroidal row of the internal RMP coils or two poloidally separated rows of coils. ELM suppression with a single row of internal coils was achieved at approximately the same q sub(95) surface-averaged perturbation field as with two rows of coils, but required higher current per coil. Maintaining complete suppression of ELMs using n = 3 RMPs from a single toroidal row of internal coils was less robust to variations in input neutral beam injection torque than previous ELM suppression cases using both rows of internal coils. With either configuration of RMP coils, maximum ELM size is correlated with the width of the edge region having good overlap of the magnetic islands from vacuum field calculations.

At present, poloidally separated recycling and neutral pressure measurements are used to characterize recycling flux trends. The causes of monotonic density increases observed in initial phases of H-mode discharges at t[less-than-or-equals, slant]0.2-0.6 s appear to be the monotonically increasing source in the divertor, and particle containment time [MathML equation] long in comparison with discharge duration. The ratio of the wall flux to divertor flux is low throughout the density increase phase except in the initial segment, when N sub(e)/dt is highest and magnitudes of the wall and divertor fluxes are similar.

AN - 67220477; 19427512 AB - Elaborate processes act at the DNA replication fork to minimize the generation of chromatid discontinuity when lesions are encountered. To prevent collapse of stalled replication forks, mutagenic translesion synthesis (TLS) polymerases are recruited temporarily to bypass DNA lesions. When a replication-associated (one-ended) double-strand break occurs, homologous recombination repair (HRR) can restore chromatid continuity in what has traditionally been regarded as an "error-free" process. Our previous mutagenesis studies show an important role for HRR in preventing deletions and rearrangements that would otherwise result from error-prone nonhomologous end joining (NHEJ) after fork breakage. An analogous, but distinct, role in minimizing mutations is attributed to the proteins defective in the cancer predisposition disease Fanconi anemia (FA). Cells from FA patients and model systems show an increased proportion of gene-disrupting deletions at the hprt locus as well as decreased mutation rates in the hprt assay, suggesting a role for the FANC proteins in promoting TLS, HRR, and possibly also NHEJ. It remains unclear whether HRR, like the FANC pathway, impacts the rate of base substitution mutagenesis. Therefore, we measured, in isogenic rad51d and fancg CHO mutants, mutation rates at the Na(+)/K(+)-ATPase alpha-subunit (ATP1A1) locus using ouabain resistance, which specifically detects base substitution mutations. Surprisingly, we found that the spontaneous mutation rate was reduced approximately 2.5-fold in rad51d knockout cells, an even greater extent than observed in fancg cells, when compared with parental and isogenic gene-complemented control lines. A approximately 2-fold reduction in induced mutations in rad51d cells was seen after treatment with the DNA alkylating agent ethylnitrosurea while a lesser reduction occurred in fancg cells. Should the model ATP1A1 locus be representative of the genome, we conclude that at least 50% of base substitution mutations in this mammalian system arise through error-prone polymerase(s) acting during HRR-mediated restart of broken replication forks.

Absolute amplitude measurements are made on hand-selected and carefully windowed seismograms for tens of stations and thousands of crustal earthquakes resulting in excellent coverage of the region. A conjugate gradient method is used to tomographically invert the amplitude data set of over 8000 paths over a 45 degrees X 40 degrees region of the Middle East. We solve for Q variation, as well as site and source terms, for a wide range of frequencies ranging from 0.5 to 10 Hz. We have modified the standard attenuation tomography technique to more explicitly define the earthquake source expression in terms of the seismic moment. This facilitates the use of the model to predict the expected amplitudes of new events, an important consideration for earthquake hazard or explosion monitoring applications. The attenuation results have a strong correlation to tectonics. Shields have low attenuation, whereas tectonic regions have high attenuation, with the highest attenuation at 1 Hz found in eastern Turkey. The results also compare favourably to other studies in the region made using Lg propagation efficiency, Lg/Pg amplitude ratios and two-station methods. We tomographically invert the amplitude measurements for each frequency independently. In doing so, it appears the frequency dependence of attenuation in all regions is not compatible with the power-law representation of Q( f ), an assumption that is often made.

The most common approach is to link velocity and density through relative scaling or conversion factors: R (sub rho /s) =dlnrho /dlnV (sub S) . However, the range of possible R (sub rho /s) values remains large even when only considering thermal effects. We directly test the validity of several proposed depth-dependent conversion profiles developed from mineral physics studies for thermally-varying properties of mantle materials. The tests are conducted by simultaneously inverting shear wave traveltime data and a diverse suite of convection-related constraints interpreted with viscous-flow response functions of the mantle. These geodynamic constraints are represented by surface spherical harmonic basis functions (up to harmonic degree 16) and they consist of the global free-air gravity field, tectonic plate divergences, dynamic surface topography and the excess ellipticity of the core-mantle boundary (CMB). The tests yield an optimum 1-D thermal R (sub rho /s) profile that is generally compatible with all considered data, with the exception of the dynamic surface topography that is most sensitive to the shallow upper mantle. This result is not surprising given that cratonic roots are known to be compositionally-distinct from the surrounding ambient mantle. Moreover, it is expected that the temperature-dependence of the thermal R (sub rho /s) in the upper mantle is significant due to the temperature-dependence of seismic attenuation or Q. Therefore, a simple 1-D density-velocity relationship is insufficient. To address this problem, we obtained independent estimates of the first-order correction factors to the selected R (sub rho /s) profile within the cratonic roots and in the ambient (thermal) upper mantle. These correction factors, defined as theta R (sub rho /s) /theta lnV (sub S) , are highly negative within the cratons signifying considerable compositional buoyancy. This result confirms that the negative buoyancy associated with the low temperatures in the cratons is significantly counteracted by the composition-induced positive buoyancy resulting in near-neutral buoyancy of the cratonic roots. Within the ambient upper mantle, the correction factors are found to be positive which is consistent with the expected behaviour of the R (sub rho /s) relationship in thermally-varying upper-mantle material. We obtain a significantly greater reconciliation of the global gravity anomalies and dynamic surface topography when applying these laterally-varying corrections compared to a simple 1-D R (sub rho /s) relationship. Inversion for a fully 3-D R (sub rho /s) relationship reveals secondary effects including additional compositional variation within the cratonic roots and the deep-mantle superplume structures. We estimate the relative magnitude of the thermal and compositional (non-thermal) contributions to mantle density anomalies and conclude that thermal effects dominate shear wave and density heterogeneity throughout the non-cratonic mantle. We also demonstrate the potential pitfalls of scaling a purely seismically-derived model to obtain density rather than performing a true joint inversion to obtain velocity and density simultaneously.

Homology modeling of SpaK and SpaR yielded preliminary structural models based on a best template for SpaK comprising a dimer of a histidine kinase, and for SpaR a response regulator protein. Our LGA code was used to identify multi-domain proteins with structure homology to both modeled structures, yielding a set of domain-fusion templates then used to model a hypothetical SpaK/SpaR complex. The models were used to identify putative functional residues and residues at the protein-protein interface, and bioinformatics was used to compare functionally and structurally relevant residues in corresponding positions among proteins with structural homology to the templates. Models of the complex were evaluated in light of known properties of the functional residues within two-component systems involving His-Asp phosphorelays. Based on this analysis, a phosphotransferase complexed with a beryllofluoride was selected as the optimal template for modeling a SpaK/SpaR complex conformation. In vitro phosphorylation studies performed using wild type and site-directed SpaK mutant proteins validated the predictions derived from application of the structure-driven domain-fusion method: SpaK was phosphorylated in the presence of super(32)P-ATP and the phosphate moiety was subsequently transferred to SpaR, supporting the hypothesis that SpaK and SpaR function as sensor and response regulator, respectively, in a two-component signal transduction system, and furthermore suggesting that the structure-driven domain-fusion approach correctly predicted a physical interaction between SpaK and SpaR. Our domain-fusion algorithm leverages quantitative structure information and provides a tool for generation of hypotheses regarding protein function, which can then be tested using empirical methods. Author Summary Because proteins so frequently function in coordination with other proteins, identification and characterization of the interactions among proteins are essential for understanding how proteins work. Computational methods for identification of protein-protein interactions have been limited by the degree to which proteins are similar in sequence. However, methods that leverage structure information can overcome this limitation of sequence-based methods; the three-dimensional information provided by structure enables identification of related proteins even when their sequences are dissimilar. In this work we present a quantitative method for identification of protein interacting partners, and we demonstrate its use in modeling the structure of a hypothetical complex between two proteins that function in a bacterial signaling system. This quantitative approach comprises a tool for generation of hypotheses regarding protein function, which can then be tested using empirical methods, and provides a basis for high-throughput prediction of protein-protein interactions, which could be applied on a whole-genome scale.

The velocity dataset, which includes 230 measurements, is interpolated across the model using depth-dependent correlations of velocity with sediment type. The sediment-type database contains more than 1400 well and borehole logs. Sediment sequences reported in logs are assigned to one of four units. A characteristic shear-wave velocity profile is developed for each unit by analyzing closely-spaced pairs of velocity profiles and well or borehole logs. The resulting velocity model exhibits reasonable values and patterns, although it does not explicitly honor the measured shear-wave velocity profiles. Site response investigations that applied a preliminary version of the velocity model support a two-zone ground-shaking hazard model for the valley. Areas in which clay predominates in the upper 30 m are predicted to have stronger ground motions than the rest of the basin.

This modeling study, which considers both dense-gas turbulence suppression and deposition to environmental objects (e.g. buildings), demonstrates that dry deposition to environmental objects may play a significant role in reducing the distance at which adverse impacts occur-particularly under low-wind, stable atmospheric conditions which are often considered to be the worst-case scenario for these types of releases. The degree to which the released chemical sticks to (or reacts with) environmental surfaces is likely a key parameter controlling hazard extents. In all modeled cases, the deposition to vertical surfaces of environmental objects (e.g. building walls) was more efficient in reducing atmospheric chemical concentrations than deposition to the earth's surface. This study suggests that (1) hazard extents may vary widely by release environment (e.g. grasslands vs. suburbia) and release conditions (e.g. sunlight or humidity may change the rate at which chemicals react with a surface) and (2) greenbelts (or similar structures) may dramatically reduce the impacts of large-scale releases. While these results are demonstrated to be qualitatively consistent with the downwind extent of vegetation damage in two chlorine releases, critical knowledge gaps exist and this study provides recommendations for additional experimental studies.

AN - 851751394; 19358574 AB - Tetramethylenedisulfotetramine, commonly known as tetramine, is a highly neurotoxic rodenticide (human oral LD(50) = 0.1 mg/kg) used in hundreds of deliberate and accidental food poisoning events in China. This paper describes a method for the quantitation of tetramine spiked into beverages, including milk, juice, tea, cola, and water, with cleanup by C8 solid phase extraction and liquid-liquid extraction. Quantitation by high-performance liquid chromatography-tandem mass spectrometry (LC-MS/MS) was based upon fragmentation of m/z 347 to m/z 268. The method was validated by gas chromatography-mass spectrometry (GC-MS) operated in selected ion monitoring mode for ions m/z 212, 240, and 360. The limit of quantitation was 0.10 μg/mL by LC-MS/MS versus 0.15 μg/mL for GC-MS. Fortifications of the beverages at 2.5 and 0.25 μg/mL were recovered ranging from 73 to 128% by liquid-liquid extraction for GC-MS analysis, from 13 to 96% by SPE, and from 10 to 101% by liquid-liquid extraction for LC-MS/MS analysis.

2009-048497 AB - All exposed rocks on Earth's surface experience erosion; the fastest rates are documented in rapidly uplifted monsoonal mountain ranges, and the slowest occur in extreme cold or warm deserts--millennial submeter-scale erosion may be approached only in the latter. The oldest previously reported exposure ages are from boulders and clasts of resistant lithologies lying at the surface, and the slowest reported erosion rates are derived from bedrock outcrops or boulders that erode more slowly than their surroundings; thus, these oldest reported ages and slowest erosion rates relate to outstanding features in the landscape, while the surrounding landscape may erode faster and be younger. We present erosion rate and exposure age data from the Paran Plains, a typical environment in the Near East where vast abandoned alluvial surfaces (10 (super 2) -10 (super 4) km (super 2) ) are covered by well-developed desert pavements. These surfaces may experience erosion rates that are slower than those documented elsewhere on our planet and can retain their original geometry for more than 2 m.y. Major factors that reduce erosion converge in these regions: extreme hyperaridity, tectonic stability, flat and horizontal surfaces (i.e., no relief), and effective surface armoring by a clast mosaic of highly resistant lithology. The (super 10) Be concentrations in amalgamated desert pavement chert clasts collected from abandoned alluvial surfaces in the southern Negev, Israel (representing the Sahara-Arabia Deserts), indicate simple exposure ages of 1.5-1.8 Ma or correspond to maximum erosion rates of 0.25-0.3 m m.y. (super -1) . The (super 36) Cl in carbonate clasts, from the same pavement, weathers faster than the chert and yields simple exposure ages of 430-490 ka or maximum erosion rates of 0.7-0.8 m m.y. (super -1) . These ages and rates are exceptional because they represent an extensive landform. The (super 10) Be concentrations from samples collected at depth and optically stimulated luminescence (OSL) dating reveal a two-stage colluvial deposition history followed by eolian addition of 40 cm of silt during the past 170 k.y. Our results highlight the efficiency of desert pavement armor in protecting rocks from erosion and preserving such geomorphic surfaces for millions of years.

The first set examined the effect of P on solid metal/liquid metal partitioning behavior of 22 elements, while the other set explored the effect of the crystal structures of body-centered cubic (alpha )- and face-centered cubic (gamma )-solid Fe alloys on partitioning behavior. Overall, the effect of P on the partition coefficients for the majority of the elements was minimal. As, Au, Ga, Ge, Ir, Os, Pt, Re, and Sb showed slightly increasing partition coefficients with increasing P-content of the metallic liquid. Co, Cu, Pd, and Sn showed constant partition coefficients. Rh, Ru, W, and Mo showed phosphorophile (P-loving) tendencies. Parameterization models were applied to solid metal/liquid metal results for 12 elements. As, Au, Pt, and Re failed to match previous parameterization models, requiring the determination of separate parameters for the Fe-Ni-S and Fe-Ni-P systems. Experiments with coexisting alpha and gamma Fe alloy solids produced partitioning ratios close to unity, indicating that an alpha versus gamma Fe alloy crystal structure has only a minor influence on the partitioning behaviors of the trace element studied. A simple relationship between an element's natural crystal structure and its alpha /gamma partitioning ratio was not observed. If an iron meteorite crystallizes from a single metallic liquid that contains both S and P, the effect of P on the distribution of elements between the crystallizing solids and the residual liquid will be minor in comparison to the effect of S. This indicates that to a first order, fractional crystallization models of the Fe-Ni-S-P system that do not take into account P are appropriate for interpreting the evolution of iron meteorites if the effects of S are appropriately included in the effort.

Corrected amplitudes can be used in ratios to discriminate between earthquakes and explosions. However, source effects remain that cannot easily be determined and applied as amplitude corrections, such as those due to depth, focal mechanism, local material property, and apparent stress variability. We develop a mathematical model to capture these near-source effects as random (unknown), giving an error partition of three sources: model inadequacy, station noise, and amplitude correlation. This mathematical model is the basis for a general multistation regional discriminant formulation. The standard error of the discriminant includes the variances of model inadequacy and station noise, along with amplitude correlation in its formulation. The developed methods are demonstrated for a collection of Nevada test site (NTS) events observed at regional stations (see Fig. 1). Importantly, the proposed formulation includes all corrected amplitude information through the construction of multistation discriminants. In contrast, previous studies have only computed discriminants from single stations having both P and S amplitudes. The proposed multistation approach has similarities to the well-established m (sub b) versus M (sub s) discriminant and represents a new paradigm for the regional discrimination problem.

Prior information on any of the multiple-event parameters may be used. The phase-label model includes a null label that captures phases not belonging to the collection of phases under consideration. Using the Markov-Chain Monte Carlo method, samples are drawn from the multiple-event joint probability function to infer the posteriori distribution that is consistent with priors and the arrival-time data set. Using this approach phase-label error can be accessed and phase-label error is propagated to all other multiple-event parameters. We test the method using a ground-truth data set of nuclear explosions at the Nevada Test Site. We find that posteriori phase labels agree with the meticulously analysed data set in more than 97 per cent of instances and the results are robust even when the input phase-label information is discarded. Only when a large percentage of the arrival-time data are corrupted does prior phase label information improve resolution of multiple-event parameters. Simultaneous modelling of the entire multiple-event system results in accurate posteriori probability regions for each multiple-event parameter. Abstract Copyright (2009), RAS.

The Devil's Kitchen rhyolite from the Coso volcanic field in southeastern California (elev. nearly equal 1300 m) was chosen for this study due to its young age ( nearly equal 610 ka) and diverse mineral assemblage. Based on (super 10) Be, our two rhyolite samples have apparent exposure ages of nearly equal 49 and 93 ka, indicating substantial erosion after eruption. Combining data from the two samples, we estimate sea level high latitude (super 3) He spallation production rates of 145+ or -11, 141+ or -16, and 144+ or -30 at g (super -1) a (super -1) (2sigma ) for pyroxene, olivine and spessartine garnet, respectively. For zircon and apatite, we estimate apparent (super 3) He spallation production rates of 114+ or -8 and 149+ or -28 at g (super -1) a (super -1) (2sigma ), respectively. The rates for zircon and apatite are reported as apparent production rates because we do not explicitly address the redistribution of spallation produced (super 3) He from adjacent minerals. These estimates quantitatively account for production of (super 3) He from both cosmogenic and radiogenic neutron reactions on (super 6) Li within the analyzed phases and also implanted from nuclear reactions in neighboring minerals; the high U, Th and Li content of this rhyolite provides a particularly rigorous test of this correction. We estimate (super 21) Ne production rates of 17.7+ or -1.6 and 34.1+ or -3.2 at g (super -1) a (super -1) (2sigma ) in quartz and pyroxene (Fe/Mg=0.7 by mass), respectively.

The solar cosmic ray (SCR) produced (super 26) Al and (super 36) Cl in this rock are present in high concentrations, which in combination with the low observed erosion rate, <0.5mm/Myr, provide well defined depth profiles characterizing the SCR component of the cosmic rays. In conjunction with new experimentally determined excitation functions, the (super 36) Cl concentrations suggest a softer solar-proton spectral shape than that derived from most previous measurements. The fact that no SCR-produced (super 10) Be activity could be detected in 64455 is in good agreement with observations in 68815 and also indicates a softer SCR spectrum. Comparison of observed SCR profiles in 64455 with theoretical calculations indicates that the average solar-proton spectrum over the past 2 Myr (based on (super 26) Al) has an exponential rigidity parameter (R (sub 0) ) of about 90MV with a proton flux (J) of 73 protons/cm (super 2) /s.4pi above 10M eV. Over the last approximately 0.5 Myr (based on (super 36) Cl) R (sub 0) is about 70 MV with a flux of approximately 196 protons/cm (super 2) /s.4pi above 10M eV. These SCR fluxes are consistent with most previous work. Abstract Copyright (2009) Elsevier, B.V.

Permeability varies by several orders of magnitude among volcanic clasts and does not depend solely upon porosity. Electrical property measurements of saturated volcanic samples illustrate the influence of pathway tortuosity and pore shape on permeability. For equivalent eruption conditions, silicic samples show higher tortuosities, smaller vesicle sizes, and lower permeabilities than mafic samples. These differences are largely due to variations in vesiculation and crystallization history. Differences between explosive and effusive samples reflect the relative ability of bubbles to form and maintain connected pathways during bubble expansion and collapse. Isotropic samples (variably expanded breadcrust bombs and most pumice fall samples) have pore pathways that simplify with increasing porosity. Highly vesicular anisotropic samples (e.g., tube pumice) have high permeabilities and low tortuosities parallel to pore elongation and low permeabilities and high tortuosities perpendicular to elongation. These pathways simplify with increasing deformation (i.e., tortuosity decreases as porosity decreases), until pore geometries collapse sufficiently to form intersecting cracks. More generally, Archie's Law (power law) relationships between electrical conductivity formation factor (F) and porosity (phi ) have an Archie's exponent, m, between 1 and 4 (where F=phi (super -m) ) for low porosity volcanic clasts. However, samples with higher connected porosities (>20% for silicic samples and >50% for mafic samples) have m values that increase with increasing porosity, reaching up to 15. We also find that a single Archie's Law fit to a suite of samples is not appropriate either for sample suites with widely varying porosities or for anisotropic samples with a directional variation in measured properties. These measurements caution against simple application of cross-property relationships derived from sedimentary rocks to models of permeability in volcanic samples.

Leakage back to the atmosphere through abandoned wells and along faults would reduce the efficiency of carbon storage, possibly leading to health and ecological hazards at the ground surface, and possibly impacting water quality of near-surface dilute aquifers. We use static equilibrium and reactive transport simulations to test the hypothesis that perturbations in water chemistry associated with a CO2 gas leak into dilute groundwater are important measures for the potential release of CO2 to the atmosphere. Simulation parameters are constrained by groundwater chemistry, flow, and lithology from the High Plains aquifer. The High Plains aquifer is used to represent a typical sedimentary aquifer overlying a deep CO2 storage reservoir. Specifically, we address the relationships between CO2 flux, groundwater flow, detection time and distance. The CO2 flux ranges from 10 (super 3) to 2 x 10 (super 6) t/yr (0.63 to 1250 t/m (super 2) /yr) to assess chemical perturbations resulting from relatively small leaks that may compromise long-term storage, water quality, and surface ecology, and larger leaks characteristic of short-term well failure.

AN - 742774411; pmid-19275301 AB - A laser-based ultrasonic technique suitable for characterization of the microstructural state of metal foils is presented. The technique relies on the measurement of the intrinsic attenuation of laser-generated longitudinal waves at frequencies reaching 1 GHz resulting from ultrasonic interaction with the sample microstructure. In order to facilitate accurate measurement of the attenuation, a theoretical model-based signal analysis approach is used. The signal analysis approach isolates aspects of the measured attenuation that depend strictly on the microstructure from geometrical effects. Experimental results obtained in commercially cold worked tungsten foils show excellent agreement with theoretical predictions. Furthermore, the experimental results show that the longitudinal wave attenuation at gigahertz frequencies is strongly influenced by the dislocation content of the foils and may find potential application in the characterization of the microstructure of micron thick metal foils.

Remote sensing, geomorphic mapping, and (super 10) Be terrestrial cosmogenic nuclide (TCN) surface-exposure dating of boulders on the moraines and sediment in depth profiles show that glaciers advanced at least 12 times during at least the last two glacial cycles. Over this time, the style of glaciation changed progressively from one that produced ice caps to one that produced less extensive and more deeply entrenched valley glaciers. The timing of the two earliest glaciations is poorly defined, but they likely occurred prior to the penultimate glacial cycle (the Karasu glacial stage) and the early part of the last glacial cycle or during the penultimate glacial cycle (the Subaxh glacial stage). In contrast, the timing of later glacial advances (the Olimde glacial stage) is relatively well defined showing quasiperiodical oscillations on millennial time scales (17.1+ or -0.3 ka, 13.7+ or -0.5 ka, 11.2+ or -0.1 ka, 10.2+ or -0.3 ka, 8.4+ or -0.4 ka, 6.7+ or -0.2 ka, 4.2+ or -0.3 ka, 3.3+ or -0.6 ka, 1.4+ or -0.1 ka, and a few hundred years before the present). These data suggest that since the global Last Glacial Maximum (LGM), the glaciers in western Tibet likely responded to Northern Hemisphere climate oscillations (rapid climate changes), with minor influences from the south Asian monsoon. This study provides the first well-defined glacial geologic evidence to suggest that glaciers in western Tibet respond to rapid climate changes on millennial time scales throughout the Late Glacial and Holocene.

Lessons from the early to middle Holocene AN - 50477093; 2009-032323 AB - The coral Acropora cervicornis is considered a modern environmental indicator species, vulnerable to anthropogenic stress and rapidly disappearing throughout the Caribbean. Causes for its decline have been attributed to both natural and anthropogenic factors. Physical and geochemical data are used to explore conditions under which this species thrived in early to middle Holocene reef deposits (ca. 9.4-5.4 ka) of the Enriquillo Valley, southwestern Dominican Republic. This study shows that A. cervicornis flourished during a 4000 yr period spanning the Holocene Thermal Maximum, and high-resolution radiocarbon dating reveals continuous growth for at least 2000 yr. Holocene A. cervicornis survived large-scale climate and environmental changes that included high temperatures, variable salinity, hurricanes, and rapid sea-level rise with remarkable resilience. Our data suggest that the recent decline in A. cervicornis is anomalous and likely tied to ecosystem change beyond natural causes.

Deep-sea coral communities are hotspots of deep ocean biomass and biodiversity, providing critical habitat for fish and invertebrates. Newly applied radiocarbon age dates from the deep water proteinaceous corals Gerardia sp. and Leiopathes sp. show that radial growth rates are as low as 4 to 35 mu year (super -1) and that individual colony longevities are on the order of thousands of years. The longest-lived Gerardia sp. and Leiopathes sp. specimens were 2,742 years and 4,265 years, respectively. The management and conservation of deep-sea coral communities is challenged by their commercial harvest for the jewelry trade and damage caused by deep-water fishing practices. In light of their unusual longevity, a better understanding of deep-sea coral ecology and their interrelationships with associated benthic communities is needed to inform coherent international conservation strategies for these important deep-sea habitat-forming species.

Current methods to confirm the presence of a viable biothreat agent are limited by low sample throughput. We have developed a rapid-viability-polymerase chain reaction (RV-PCR) method to determine the presence of viable spores. The method combines high-throughput sample processing with 96-well PCR analysis, which measures a change in real-time, quantitative PCR response arising from increased target-cell populations during culturing. The method accurately detects 1 to 10 live spores in a high-dead spore background (10 super(6)). Field tests using approximately 1000 biological indicators, each containing 10 super(6) spores of the B. anthracis surrogate, Bacillus atrophaeus, exposed to seven lethal and sub-lethal chlorine dioxide levels showed no significant difference (p>0.05) between RV-PCR and standard culturing methods for detecting the percent survival of spores. RV-PCR results were obtained in <17 h compared to 7 days for the standard culturing method. High-throughput sample processing and RV-PCR protocols were also developed and tested for synthetic wipe samples containing reference dirt material. RV-PCR protocols allowed processing and accurate analysis of ~100 dirty wipe samples (2''x2'' synthetic) containing ~10 viable B. atrophaeus spores in <24 h. Quantitative RV-PCR protocols based on a Most-Probable-Number (MPN) statistical approach developed for B. anthracis Sterne resulted in more rapid turnaround times than those for traditional culturing and no significant difference in log colony-forming units compared to traditional viability analysis. Integration of RV-PCR assays with high-throughput protocols will allow the processing of 200 wipe samples per day per robot using commercially available automation.

However, the exact type of nanoparticle and the speciation of the associated radionuclides has remained unknown. We have investigated nanoparticles sampled from the far-field at the Nevada Test Site, Nevada, utilizing advanced electron microscopy techniques, including high-angle annular dark-field scanning TEM (HAADF-STEM). Fissiogenic elements: Cs, rare earth elements (REE), activation elements: Co; and actinides: U and Th, were detected. Cesium is associated with U-forming cesium uranate with a Cs/U atomic ratio of 0.12. Light REEs and Th are associated with phosphates, silicates, or apatite. Cobalt occurs as a metallic aggregate, associated with Cr, Fe, Ni, and c Mo. Uranyl minerals; Na-boltwoodite and oxide hydrates are also present as colloids. Because of these chemical associations with nanoscale particles, in the size range <100 nm, these particles may facilitate transport, and a variety of trace nanoscale phases may be responsible for the migration of fissiogenic and actinide elements in groundwater. To accurately model the transport of these contaminants, predictive transport models should include consideration of nanoparticle-facilitated transport.

2013-009797 AB - The properties of hydrogen-helium mixtures at Mbar pressures and intermediate temperatures (4000 to 10000 K) are calculated with first-principles molecular dynamics simulations. We determine the equation of state as a function of density, temperature, and composition and, using thermodynamic integration, we estimate the Gibbs free energy of mixing, thereby determining the temperature, at a given pressure, when helium becomes insoluble in dense metallic hydrogen. These results are directly relevant to models of the interior structure and evolution of Jovian planets. We find that the temperatures for the demixing of helium and hydrogen are sufficiently high to cross the planetary adiabat of Saturn at pressures approximately 5 Mbar; helium is partially miscible throughout a significant portion of the interior of Saturn, and to a lesser extent in Jupiter.

(2003) to earthquake data in and around the Nevada Test Site (NTS) using four regional broadband stations from the Lawrence Livermore National Laboratory (LLNL) seismic network. We applied the same path and site corrections to tamped nuclear explosion data and averaged the source spectra over the four stations. Narrowband coda amplitudes from the spectra were then regressed against inferred yield based on the regional m (sub b) (Pn) magnitude of Denny et al. (1987), along with the yield formulation of Vergino and Mensing (1990). We find the following: (1) the coda-derived spectra show a peak that is dependent upon emplacement depth, not event size; (2) source size estimates are stable for the coda and show a dependence upon the near-source strength and gas porosity; (3) for explosions with the same m (sub b) (Pn) or inferred yield, those in weaker material have lower coda amplitudes at 1-3 Hz.

A novel and potentially counteracting metabolic process, anaerobic, nitrate-dependent U(IV) oxidation, has recently been described in two bacterial species (Geobactermetallireducens and Thiobacillusdenitrificans), but the underlying biochemistry and genetics are completely unknown. We report here that two diheme, c-type cytochromes (putatively c sub(4) and c sub(5) cytochromes) play a major role in nitrate-dependent U(IV) oxidation by T.denitrificans. Insertion mutations in each of the two genes encoding these cytochromes resulted in a greater than 50% decrease in U(IV) oxidation activity, and complementation intrans restored activity to wild-type levels. Sucrose-density-gradient ultracentrifugation confirmed that both cytochromes are membrane-associated. Insertion mutations in genes encoding other membrane-associated, c-type cytochromes did not diminish U(IV) oxidation. This is the first report of proteins involved in anaerobic U(IV) oxidation.

Individual unfixed, paraformaldehyde-fixed, and methanol-fixed normal and transformed lymphocytes from three different cell lines were analyzed with LTRS. When compared to the spectra of unfixed cells, the fixed cell spectra show clear, reproducible changes in the intensity of specific Raman markers commonly assigned to DNA, RNA, protein, and lipid vibrations (e.g. 785, 1230, 1305, 1660 cm-1) in mammalian cells, many of which are important markers that have been used to discriminate between normal and cancer lymphocytes. Statistical analyses of the Raman data and classification using principal component analysis and linear discriminant analysis indicate that methanol fixation induces a greater change in the Raman spectra than paraformaldehyde. In addition, we demonstrate that the spectral changes as a result of the fixation process have an adverse effect on the accurate Raman discrimination of the normal and cancer cells. The spectral artifacts created by the use of fixatives indicate that the method of cell preparation is an important parameter to consider when applying Raman spectroscopy to characterize, image, or differentiate between different fixed cell samples to avoid potential misinterpretation of the data.

As a first step, we investigate reaction rates and mechanistic pathways for cement mineral growth in the absence of CO2 by coupling water chemistry with XRD and NMR spectroscopic data. We find that semi-crystalline calcium (alumino-)silicate hydrate (Al-CSH) forms as a precursor solid to the cement mineral tobermorite. Rate constants for tobermorite growth were found to be k = 0.6 (+ or - 0.1) X 10-5 s-1 for a solution:solid of 10:1 and 1.6 (+ or - 0.8) X 10-4 s-1 for a solution:solid of 5:1 (batch mode; T = 150 degrees C). This data indicates that reaction rates for tobermorite growth are faster when the solution volume is reduced by half, suggesting that rates are dependent on solution saturation and that the Gibbs free energy is the reaction driver. However, calculated solution saturation indexes for Al-CSH and tobermorite differ by less than one log unit, which is within the measured uncertainty. Based on this data, we consider both heterogeneous nucleation as the thermodynamic driver and internal restructuring as possible mechanistic pathways for growth. We also use NMR spectroscopy to characterize the site symmetry and bonding environment of Al and Si in a reacted tobermorite sample. We find two Al coordination structures at ? iso = 59.9 ppm and 66.3 ppm with quadrupolar product parameters (PQ) of 0.21 MHz and 0.10 MHz (+ or - 0.08) from 27Al 3Q-MAS NMR and speculate on the Al occupancy of framework sites by probing the protonation environment of Al metal centers using (super 27) Al {H}CP-MAS NMR.

An earthquake source is inconsistent with the data and the best-fit full seismic moment tensor is dominantly explosive ( approximately 60%) with a moment magnitude (M (sub W) ) of 4.5. A pure explosion solution yields a scalar seismic moment of 1.8X10 (super 22) dyne-cm (M (sub W) 4.1) and fits the data almost as well as the full solution. The difference between the full and explosion solutions is the predicted fit to observed tangential displacement, which requires some type of non-isotropic (non-explosive) radiation. Possible causes of the tangential displacement are additional tectonic sources, tensile failure at depth, and anisotropic wave propagation. Similar displacements may be hidden in the noise of the 2006 event. Future analyses of this type could be used to identify and characterize non-earthquake events such as explosions and mine collapses.

This plate-coupled mantle convection model incorporates a viscosity structure that reconciles both glacial isostatic adjustment and global convection-related data sets. The convection model successfully reproduces present-day plate velocities and global surface gravity and topography constraints. We predict time-dependent changes in mantle buoyancy that give rise to present-day decelerations of several major plates, in particular the fast-moving Pacific and Nazca plates. We verify the plausibility of these predicted plate decelerations using space geodetic and oceanic magnetic anomaly constraints on tectonic plate motions. These plate kinematic constraints are employed to determine a new global map of present-day plate decelerations that agree well with the mantle flow predictions.

For large parts of both Archaean and Proterozoic terrains, the velocity models obtained from the inversions show shear wave velocities > or =4.0 km/s below approximately 20-30 km depth, indicating a predominantly mafic lower crust. However, for much of the Kimberley terrain and adjacent parts of the Kheis Province and Witwatersrand terrain in South Africa, as well as for the western part of the Tokwe terrain in Zimbabwe, shear wave velocities of < or =3.9 km/s are found below approximately 20-30 km depth, indicating an intermediate-to-felsic lower crust. The areas of intermediate-to-felsic lower crust in South Africa coincide with regions where Ventersdorp rocks have been preserved, suggesting that the more evolved composition of the lower crust may have resulted from crustal reworking and extension during the Ventersdorp tectonomagmatic event at c. 2.7 Ga.

The onset and evolution of uplift in the central Basin and Range province and Colorado Plateau during this time is determined by tracking the topographic swell due to this mantle upwelling. We show that: (1) the extension and basaltic volcanism (post 25 Ma) in the central Basin and Range coincides with the arrival and eastward progression of this upwelling, and (2) dynamic uplift of the southern Colorado Plateau, totaling about 1 km, transpired in the last 20 Ma. Since 10 Ma, the center of uplift continued northeastward from the southwestern rim of the plateau consistent with a young Grand Canyon model and eastward sweep of magmatism in the western Colorado Plateau.

Using a simple mass balance, we show that even with Fm > 1, half of the planktonic foraminifera at the seafloor can be centuries old, because of bioturbation. This calculation, and data from four core sites in the western North Atlantic indicate that, first, during some part of the Little Ice Age (LIA) there may have been more Antarctic Bottom Water than today in the deep western North Atlantic. Alternatively, bioturbation may have introduced much older benthic foraminifera into surface sediments. Second, paleo-based warming of Sargasso Sea surface waters since the LIA must lag the actual warming because of bioturbation of older and colder foraminifera.

The prebomb surface water Delta (super 14) C average is -60.5 ppm, and individual samples range from -72 ppm to 134 ppm. The annual average postbomb maximum occurs in 1973 at 122 ppm. The timing of the postbomb maximum is consistent with a primary subtropical source for the surface waters in the Indonesian seas. During the postbomb period, the coral records regular seasonal cycles of 5 ppm to 20 ppm. Seasonal high Delta (super 14) C occur during March-May (warm, low salinity), and low Delta (super 14) C occur in September (cool, higher salinity). The Delta (super 14) C seasonality is coherent and in phase with the seasonal Delta (super 14) C cycle observed in Makassar Strait. We estimate the influence of high Delta (super 14) C Makassar Strait (North Pacific) water flowing through the Lombok Strait using a two end-member mixing model and the seasonal extremes observed at the two sites. The percentage of Makassar Strait water varies between 16% and 70%, and between 1955 and 1990, it averages at 40%. The rich Delta (super 14) C variability has a biennial component reflecting remote equatorial Indian Ocean forcing and a component in the ENSO band, which is interpreted to reflect Pacific forcing on the Delta (super 14) C signature in Lombok Strait.

While closely spaced events generally discriminate easily, the application of this technique to broad regions has been hampered by large variations in the amplitude of phases due to the attenuation of the crust and upper mantle. Making use of a recent P-wave and S-wave attenuation model of the lithosphere, we have found that correcting the events using our amplitude methodology significantly reduces the scattering in the earthquake population. We demonstrate an application of this technique to station NIL using broad-area earthquakes and the 1998 Indian nuclear explosion using the Pn/Lg discriminant in the 1-2 Hz passband. We find that the explosion, which is lost in the scatter of the earthquakes in the uncorrected discriminant, clearly separates by correcting for attenuation structure. We see a similar reduction in scatter and separation for the Pn/Sn and Pg/Lg discriminants.

AN - 66752549; 19064306 AB - Coconut trees growing on atolls of the Bikini Islands are on the margin of K deficiency because the concentration of exchangeable K in coral soil is very low, ranging from only 20 to 80mgkg(-1). When provided with additional K, coconut trees absorb large quantities of K and this uptake of K significantly alters the patterns of distribution of 137Cs within the plant. Following a single K fertilization event, mean total K in trunks of K-treated trees is 5.6 times greater than in trunks of control trees. In contrast, 137Cs concentration in trunks of K-treated and control trees is statistically the same while 137Cs is significantly lower in edible fruits of K-treated trees. Within one year after fertilization (one rainy season), K concentration in soil is back to naturally low concentrations. However, the tissue concentrations of K in treated trees stays very high internally in the trees for years while 137Cs concentration in treated trees remains very low in all tree compartments except for the trunk. Potassium fertilization did not change soil Cs availability. Mass balance calculations suggest that the fertilization event increased above ground plant K content by at least a factor of 5 (2.2kg). Potassium concentrations and content were higher in all organs of K-fertilized trees with the greatest increases seen in organs that receive a portion of tissue K through xylem transport (trunk, fronds and fruit husks) and lowest in organs supplied predominantly with K via the phloem (palm heart, spathe, coco meat and fluid). The 137Cesium concentrations and contents were dramatically lower in all organs of K-treated trees with greatest proportional reductions observed in organs supplied predominantly with K via the phloem (palm heart, spathe, coco meat and fluid). All trees remobilize both K and 137Cs from fronds as they proceed toward senescence. In control trees the reduction in concentration of K and 137Cs in fronds as they age is logarithmic, but K remobilization is linear in K-treated trees where K concentration is high. As a result of K treatment the 137Cs concentration in K-treated fronds is extremely low and constant with frond age. Fronds of K-treated trees contain a greater amount of K than control tree fronds. As they fall to the ground and decay they provide a small continuing pool of K that is about 3% of the natural K in soil under the tree canopy. Results of K and 137Cs concentration and distribution in control and K-treated coconut trees suggest that the application of K reduces 137Cs uptake both in the short term immediately following K fertilization and in the long term, after soil K levels have returned to normal but while plant K stores remain high. These results suggest that high internal K concentration and not high soil K is primarily responsible for long-term reduction of 137Cs in edible fruits, play a significant role in limiting further uptake of 137Cs by roots, and affects allocation of 137Cs to edible fruits for years. Coconut trees are capable of luxury K accumulation when provided with excess K and in this example the additional K can effectively provide the K requirements of the plant for in excess of 10y. The reduction of 137Cs uptake lasts for at least 10y after K is last applied and greatly reduces the estimated radiation dose to people consuming local tree foods. Effectiveness and duration of K treatment provide important assurances that reduction in 137Cs is long term and the radiation dose from consuming local plant foods will remain low.

AN - 66736408; 18930949 AB - Chromosomal mosaicism in human preimplantation embryos is a common cause of spontaneous abortions, however, our knowledge of its etiology is limited. We used multicolor fluorescence in situ hybridization painting to investigate whether paternally transmitted chromosomal aberrations result in mosaicism in mouse two-cell embryos. Paternal exposure to acrylamide, an important industrial chemical also found in tobacco smoke and generated during the cooking process of starchy foods, produced significant increases in chromosomally defective two-cell embryos, however, the effects were transient primarily affecting the postmeiotic stages of spermatogenesis. Comparisons with our previous study of zygotes demonstrated similar frequencies of chromosomally abnormal zygotes and two-cell embryos suggesting that there was no apparent selection against numerical or structural chromosomal aberrations. However, the majority of affected two-cell embryos were mosaics showing different chromosomal abnormalities in the two blastomeric metaphases. Analyses of chromosomal aberrations in zygotes and two-cell embryos showed a tendency for loss of acentric fragments during the first mitotic division of embryogenesis, whereas both dicentrics and translocations apparently underwent proper segregation. These results suggest that embryonic development can proceed up to the end of the second cell cycle of development in the presence of abnormal paternal chromosomes and that even dicentrics can persist through cell division. The high incidence of chromosomally mosaic two-cell embryos suggests that the first mitotic division of embryogenesis is prone to missegregation errors and that paternally transmitted chromosomal abnormalities increase the risk of missegregation leading to embryonic mosaicism.

To investigate the postseismic deformation after the 1984 M6.2 Morgan Hill earthquake, we identify RE sequences occurring on the central Calaveras fault between 1984 and 2005 using a combination of cross-correlation and spectral coherence techniques. Both the accelerated slip transients due to the earthquake as well as the return to interseismic background creep rates can be imaged from our dataset. A comparison between the regions of the fault that ruptured coseismically and the locations of the REs show that REs preferentially occur in areas adjacent to the coseismic rupture. Using calculated RE-derived subsurface slip distributions at 6 months and 18 months after the mainshock, we predict surface electronic distance meter (EDM) line length changes between stations near the Morgan Hill rupture area. The RE-derived slip model underpredicts a subset of the observed line-length changes. Inclusion of transient aseismic slip below the seismogenic zone is needed to better match the measured surface deformation.

In the Altos de Talinay area ( nearly equal 31 degrees S), we have identified a sequence of 5 wave-cut platforms. Using in situ produced (super 10) Be exposure ages we show that these platforms were formed during interglacial periods at 6, 122, 232, 321 and 690 ka. These ages correspond to marine isotopic stages (MIS) or substages (MISS) 1, 5e, 7e, 9c and 17. Shoreline angle elevations used in conjunction with our chronology of wave-cut platform formation, illustrate that surface uplift rates vary from 103 + or - 69 mm/ka between 122 and 6 ka, to 1158 + or - 416 mm/ka between 321 and 232 ka. The absence of preserved platforms related to the MIS 11, 13 and 15 highstands likely reflects slow uplift rates during these times. We suggest that since 700 ka, the Altos de Talinay area was predominantly uplifted during 2 short periods following MIS 17 and MISS 9c. This episodic uplift of the Chilean coast in the Pleistocene may result from subduction related processes, such as pulses of tectonic accretion at the base of the forearc wedge.

The Sm-Nd isotopic system yields a crystallization age for 78238 of 4334+ or -37Ma and an initial epsilon (sub Nd) (super 143) value of -0.27+ or -0.74. The age-initial epsilon (sub Nd) (super 143) (T-I) systematics of a variety of KREEP-rich samples, including 78238 and other Mg-suite rocks, KREEP basalts, and olivine cumulate NWA 773, suggest that lunar differentiation was completed by 4492+ or -61Ma assuming a Chondritic Uniform Reservoir bulk composition for the Moon. The Rb-Sr isotopic systematics of 78238 were disturbed by post-crystallization processes. Nevertheless, selected data points yield two Rb-Sr isochrons. One is concordant with the Sm-Nd crystallization age, 4366+ or -53Ma. The other is 4003+ or -95Ma and is concordant with an Ar-Ar age for 78236. The (super 207) Pb- (super 206) Pb age of 4333+ or -59Ma is concordant with the Sm-Nd age. The U-Pb isotopic systematics of 78238 yield linear arrays equivalent to younger ages than the Pb-Pb system, and may reflect fractionation of U and Pb during sample handling. Despite the disturbed nature of the U-Pb systems, a time-averaged mu ( (super 238) U/ (super 204) Pb) value of the source can be estimated at 27+ or -30 from the Pb-Pb isotopic systematics. Because KREEP-rich samples are likely to be derived from source regions with the highest U/Pb ratios, the relatively low mu value calculated for the 78238 source suggests the bulk Moon does not have an exceedingly high mu value.

Impressive valley fills and glacial landforms are present throughout the valleys. The dynamics of landscape evolution of the region are currently not well understood. Consequently, the landforms were mapped and assessed in the Skardu, Shigar, and Braldu valleys, to elucidate the spatio-temporal scale dependencies of surface processes active in the region. These valleys were examined using geomorphic field methods, remote sensing, geomorphometry, and terrestrial cosmogenic nuclides (TCNs) surface exposure dating. The glaciers in this region have oscillated considerably throughout the Late Quaternary, and four glacial stages have been recognized including at least six glacial advances. Surface processes readjusted after glacier retreat, and ubiquitous mass movements and catastrophic landsliding transported material from steep slopes to valley bottoms, while glaciofluvial meltwater and glacier outburst floods redistributed sediment down valley. Glacier geochronology and late Holocene ages of the outburst flood deposits indicate that landscape evolution has been dominated by glaciation and paraglaciation during the late Quaternary.

These massifs provide an excellent opportunity to test geomorphic concepts, such as the glacial buzz-saw model. Using remote sensing, digital elevation modeling, field mapping and terrestrial cosmogenic nuclide (TCN) methods, the massifs were examined to determine the relative importance of tectonics and geomorphic processes in shaping the regional landscape and to provide a framework for testing geomorphic models. The gneiss domes that underlie the peaks are the result of exhumation along the Kongur detachment fault that has unroofed the massifs at a rate of between 4-6 km/Ma over the last few million years. This has resulted in rapid uplift and active seismicity, which is exemplified by the numerous fresh fault scarps throughout the region and large historic earthquakes. The geomorphic system is dominated by glaciation and the region contains extensive successions of moraines and paraglacial landforms, including fans, terraces and landslides. Glaciers have oscillated considerably throughout the latter part of the Quaternary, and three major glacier stages are recognized (Karasu [oldest], Olimde and Subaxh [youngest] glacial stage) that include at least 10 smaller glacial advance. The style of glaciation has changed over time from expanded ice caps to piedmont glaciers to valley and cirque glaciers. This possibly reflects a change in climate and/or topographic constraints as the massifs grew and became incised. The topography and glaciers in the region vary across the massifs divided by a broadly N-S trending high ridge and watershed. The western portion, situated upwind (the stoss slopes) of the mid-latitude westerlies, that bring moisture to the region, has gentle high topography and small valley glaciers. In contrast, on the eastern leeward slopes, gradients are higher and long debris-covered valley glaciers are present. The hypsometry of the region indicate two peaks in the distribution frequency of elevation (3600-4100 m and 4400-4800 m asl). These two elevation zones are consistent in space with the former equilibrium-line altitudes during the Olimde and Subaxh glacial stages and suggest that glacial erosion (most effective at the ELA) has helped control topography. This observation supports the glacial buzz-saw hypothesis, which argues that glaciers determine hypsometry by means of rapid surface erosion. Based on TCN methods, basin-wide rates of erosion range from approximately 0.1 to 1.4 km/Ma and are five to ten times lower than the unroofing rate of both massifs. The discrepancy over different time scales suggests that initial unroofing was produced by abrupt tectonic uplift and that the unroofing of the massifs has continued at a slower pace during the Late Quaternary.

Each model received equal weight in the D&A analysis, despite large differences in the skill with which they simulate key aspects of observed climate. Here, we examine whether water vapor D&A results are sensitive to model quality. The `top 10- and `bottom 10- models are selected with three different sets of skill measures and two different ranking approaches. The entire D&A analysis is then repeated with each of these different sets of more or less skillful models. Our performance metrics include the ability to simulate the mean state, the annual cycle, and the variability associated with El Ni+/-o. We find that estimates of an anthropogenic water vapor fingerprint are insensitive to current model uncertainties, and are governed by basic physical processes that are well-represented in climate models. Because the fingerprint is both robust to current model uncertainties and dissimilar to the dominant noise patterns, our ability to identify an anthropogenic influence on observed multidecadal changes in water vapor is not affected by `screening- based on model quality.

Only a small percentage of the reservation is actively used for programmatic activities, often resulting in large areas remaining in a semi-natural state. In some cases this has benefited rare annual plant populations, as surroundings lands have been developed for residential or industrial use. However, land management activities (e.g., fire suppression) and natural disturbance can also work to the detriment of rare plant populations, at times requiring reintroduction efforts. A reintroduction/management regime that is beneficial to the rare plant populations of interest and is at best consistent with existing site programmatic activities, and at a minimum does not impact such activities, has the best potential for a positive outcome. At Lawrence Livermore National Laboratory's Site 300, reintroduction and management activities have focused on four rare annual plant populations (Amsinckia grandiflora, Blepharizonia plumosa, Eschscholzia rhombipetela and CA macrophylla). These natural and reintroduced populations are managed within the activities of this high-explosives test site, with varying degrees of success. When possible, site activities such as controlled burning and fire trail grading are conducted in a manner consistent with the biology of the species. Success is limited by the lack of complete understanding of each species' specific biology, habitat and disturbance requirements.

How these pools respond to management is poorly understood. We investigated effects of repeated applications of complete fertilizer and competing vegetation control with herbicides on C and N storage in forest-floor, fine-root, and mineral-soil C and N pools to 1-m depth at three Pinus ponderosa P. Lawson & C. Lawson var. ponderosa plantations across a site quality gradient in northern California. Belowground C pools without treatment were 66, 153, and 199 Mg C ha super(-1) for the low-, intermediate-, and high-quality sites, respectively, and N pools were 5.1, 6.7, and 6.5 Mg N ha super(-1), respectively. Treatments increased tree-bole volume at 20 yr as much as 400%, while changes in C and N pools belowground were less dramatic. Herbicide treatment increased forest- floor C pools 35% at the poorer quality site. Fertilization increased forest- floor C and N storage 46 to 106% at all sites. Fertilization decreased fine- root C pools at 0 to 0.3 m at the most productive site 43% and increased this N pool 43% at the least productive site, but did not influence fine-root pools to 1 m. Fertilization increased mineral-soil C pools on lower quality sites, resulting in 12 to 57% more belowground C storage. At the intermediate site, fertilization increased total belowground N storage 12%. Results of this study suggest that the major sequestration mechanism up to this point in stand development is through gains in tree biomass rather than storage in fine roots and soil belowground.

Radiat. Res. 171, 118-122 (2009). The first measurements of 63Ni produced by A-bomb fast neutrons (above similar to 1 MeV) in copper samples from Hiroshima encompassed distances from similar to 380 to 5062 m from the hypocenter (the point on the ground directly under the bomb). They included the region of interest to survivor studies ( similar to 900 to 1500 m) and provided the first direct validation of fast neutrons in that range. However, a significant measurement gap remained between the hypocenter and 380 m. Measurements close to the hypocenter are important as a high-value anchor for the slope of the curve for neutron activation as a function of distance. Here we report measurements of 63Ni in copper samples from the historic Hiroshima Atomic Bomb Dome, which is located similar to 150 m from the hypocenter. These measurements extend the range of our previously published data for 63Ni providing a more comprehensive and consistent A-bomb activation curve. The results are also in good agreement with calculations based on the current dosimetry system (DS02) and give further experimental support to the accuracy of this system that forms the basis for radiation risk estimates worldwide.

The two principal control parameters are Sc-region sea surface temperature (SST) and intertropical convergence zone (ITCZ) SST (which controls the temperature and mean subsidence profiles above the Sc). The direct effect of CO2 doubling (leaving all other parameters fixed) is tested and found to somewhat reduce liquid water path; discussion of this effect on the SST-change simulations is included. The presence of a cold boundary layer is found to significantly affect the temperature and subsidence rate just above cloud top by enhancing lower-tropospheric diabatic cooling in this region. A simple representation of this effect (easily generalizable to a more realistic boundary layer model) is developed. Steady-state solutions are analyzed as a function of local and ITCZ SST. Two climate change scenarios are considered. The first scenario is an equal increase of local and ITCZ SSTs. In this case, predicted boundary layer depth and cloud thickness increase. This is found in a simplified context to result from subsidence and entrainment decreases due to increased static stability in a warmer climate. In the second case, local SST change is diagnosed from a surface energy balance under the assumption that ocean heat transport remains unchanged. In this case, predicted boundary layer depth decreases. Cloud continues to thicken with rising ITCZ SST, but at a rate much reduced in comparison to the equal-warming scenario. This cloud shading feedback keeps SST in the Sc region nearly constant as the ITCZ SST increases. Model sensitivity to aerosol indirect effects is also considered by varying the assumed droplet concentration. The resulting change in liquid water path is small, suggesting a weaker dependence on second indirect effect than found in previous studies.

When provided with additional K, coconut trees absorb large quantities of K and this uptake of K significantly alters the patterns of distribution of 137Cs within the plant. Following a single K fertilization event, mean total K in trunks of K-treated trees is 5.6 times greater than in trunks of control trees. In contrast, 137Cs concentration in trunks of K-treated and control trees is statistically the same while 137Cs is significantly lower in edible fruits of K-treated trees. Within one year after fertilization (one rainy season), K concentration in soil is back to naturally low concentrations. However, the tissue concentrations of K in treated trees stays very high internally in the trees for years while 137Cs concentration in treated trees remains very low in all tree compartments except for the trunk. Potassium fertilization did not change soil Cs availability. Mass balance calculations suggest that the fertilization event increased above ground plant K content by at least a factor of 5 (2.2 kg). Potassium concentrations and content were higher in all organs of K-fertilized trees with the greatest increases seen in organs that receive a portion of tissue K through xylem transport (trunk, fronds and fruit husks) and lowest in organs supplied predominantly with K via the phloem (palm heart, spathe, coco meat and fluid). The 137Cesium concentrations and contents were dramatically lower in all organs of K-treated trees with greatest proportional reductions observed in organs supplied predominantly with K via the phloem (palm heart, spathe, coco meat and fluid). All trees remobilize both K and 137Cs from fronds as they proceed toward senescence. In control trees the reduction in concentration of K and 137Cs in fronds as they age is logarithmic, but K remobilization is linear in K-treated trees where K concentration is high. As a result of K treatment the 137Cs concentration in K-treated fronds is extremely low and constant with frond age. Fronds of K-treated trees contain a greater amount of K than control tree fronds. As they fall to the ground and decay they provide a small continuing pool of K that is about 3% of the natural K in soil under the tree canopy. Results of K and 137Cs concentration and distribution in control and K-treated coconut trees suggest that the application of K reduces 137Cs uptake both in the short term immediately following K fertilization and in the long term, after soil K levels have returned to normal but while plant K stores remain high. These results suggest that high internal K concentration and not high soil K is primarily responsible for long-term reduction of 137Cs in edible fruits, play a significant role in limiting further uptake of 137Cs by roots, and affects allocation of 137Cs to edible fruits for years. Coconut trees are capable of luxury K accumulation when provided with excess K and in this example the additional K can effectively provide the K requirements of the plant for in excess of 10 y. The reduction of 137Cs uptake lasts for at least 10 y after K is last applied and greatly reduces the estimated radiation dose to people consuming local tree foods. Effectiveness and duration of K treatment provide important assurances that reduction in 137Cs is long term and the radiation dose from consuming local plant foods will remain low.

The data all consistently point to a substantial degree of mixing of recharge water from surface ponds with ambient groundwater in a number of nearby wells screened at depths above 60 m below ground surface. Groundwater age data indicate that the wells near the recharge ponds sample recently recharged water, as delineated by stable O and C isotope data as well as total dissolved solids, in addition to much older groundwater in various mixing proportions. Where the recharge water signature is present, the specific geochemical interactions between the recharge water and the aquifer material appear to include ion exchange reactions (comparative enrichment of affected groundwater with Na and K at the expense of Ca and Mg) and the desorption of oxyanion-forming trace elements (As, V, and Mo), possibly in response to the elevated pH of the recharge water.

Out of six examined tracks, three show presence of volatile organic components possibly injected into the aerogel during particle impacts. When particle tracks contained volatile organic material, they were found to be -CH (sub 2) -rich, while the aerogel is dominated by the -CH (sub 3) -rich contaminant. It is clear that the population of cometary particles impacting the Stardust aerogel collectors also includes grains that contained little or none of this organic component. This observation is consistent with the highly heterogeneous nature of collected grains, as seen by a multitude of other analytical techniques.

Boundary clinopyroxenes decorating spinel surfaces have compositions similar to those of coarser clinopyroxenes from the same region of the inclusion, suggesting little movement after formation. Host melilite displays no anomalous compositions near the interface and late-stage minerals are not observed, suggesting that boundary pyroxenes did not form by crystallization of residual liquid. Allende spinels display either direct spinel-melilite contact or an intervening boundary clinopyroxene between the two phases. Spinel-melilite interfacial regions in a Leoville B1 are more complex, with boundary clinopyroxene, as observed in Allende, but also variable amounts of glass, secondary calcite, perovskite, and an Mg-, Al-, OH-rich and Ca-, Si-poor crystalline phase that may be a layered double hydrate. One possible scenario of formation for the glass veins is that open system alteration of melilite produced a porous, hydrated aggregate of Mg-carpholite or sudoite + aluminous diopside that was shock melted and quenched to a glass. The hydrated crystalline phase we observed may have been a shocked remnant of the precursor phase assemblage, but is more likely to have formed later by alteration of the glass. In the mantle, boundary clinopyroxenes may have been crystallized from Ti-rich liquids formed by the direct dissolution of perovskite and an associated Sc-Zr-rich phase or as a reaction product between dissolving perovskite and liquid. In the core, any perovskite and associated Ti-enriched liquids that may have originally been present disappeared before the growth of boundary clinopyroxene, and the observed boundary clinopyroxene may have nucleated and grown from the liquid, along with the larger core clinopyroxene.

The majority of large Stardust grains (i.e. those carrying most of the cometary dust mass) probably had density of 2.4 g cm-3 (similar to soda-lime glass used in earlier calibration experiments) or greater, and porosity of 25% or less, akin to consolidated carbonaceous chondrite meteorites, and much lower than the 80% suggested for fractal dust aggregates. Although better size calibration is required for interpretation of the very smallest impacting grains, we suggest that aggregates could have dense components dominated by mu m-scale and smaller sub-grains. If porosity of the Wild 2 nucleus is high, with similar bulk density to other comets, much of the pore space may be at a scale of tens of micrometers, between coarser, denser grains. Successful demonstration of aggregate projectile impacts in the laboratory now opens the possibility of experiments to further constrain the conditions for creation of bulbous (Type C) tracks in aerogel, which we have observed in recent shots. We are also using mixed mineral aggregates to document differential survival of pristine composition and crystalline structure in diverse finegrained components of aggregate cometary dust analogues, impacted onto both foil and aerogel under Stardust encounter conditions.

The improved technical capabilities enable analyses previously not possible. Mineral structures can be directly imaged and analyzed with single-atomic-column resolution, liquids, and implanted gases can be detected, and UV-VIS optical properties can be measured. Detection limits for minor/trace elements in thin (<100 nm thick) specimens are improved such that quantitative measurements of some extend to the sub-500 ppm level. Electron energy-loss spectroscopy (EELS) can be carried out with 0.10-0.20 eV energy resolution and atomic-scale spatial resolution such that variations in oxidation state from one atomic column to another can be detected. Petrographic mapping is extended down to the atomic scale using energy-dispersive X-ray spectroscopy (EDS) and energy-filtered transmission electron microscopy (EFTEM) imaging. Technical capabilities and examples of the applications of SuperSTEM to extraterrestrial materials are presented, including the UV spectral properties and organic carbon K-edge fine structure of carbonaceous matter in interplanetary dust particles (IDPs), X-ray elemental maps showing the nanometer-scale distribution of carbon within GEMS (glass with embedded metal and sulfides), the first detection and quantification of trace Ti in GEMS using EDS, and detection of molecular H2O in vesicles and implanted H2 and He in irradiated mineral and glass grains.

704087-1 AB - Laboratory batch sorption experiments were used to investigate variations in the retardation behavior of redox-sensitive radionuclides. Water-rock compositions were designed to simulate subsurface conditions at the Nevada Test Site (NTS), where a suite of radionuclides were deposited as a result of underground nuclear testing. Experimental redox conditions were controlled by varying the oxygen content inside an enclosed glove box and by adding reductants into the testing solutions. Under atmospheric (oxidizing) conditions, radionuclide distribution coefficients varied with the mineralogic composition of the sorbent and the water chemistry. Under reducing conditions, distribution coefficients showed marked increases for (super 99) Tc (from 1.22 at oxidizing to 378 mL/g at mildly reducing conditions) and (super 237) Np (an increase from 4.6 to 930 mL/g) in devitrified tuff, but much smaller variations in alluvium, carbonate rock, and zeolitic tuff. This effect was particularly important for (super 99) Tc, which tends to be mobile under oxidizing conditions. A review of the literature suggests that iodine sorption should decrease under reducing conditions when I- is the predominant species; this was not consistently observed in batch tests. Overall, sorption of U to alluvium, devitrified tuff, and zeolitic tuff under atmospheric conditions was less than in the glove-box tests. However, the mildly reducing conditions achieved here were not likely to result in substantial U(VI) reduction to U(IV). Sorption of Pu was not affected by the decreasing Eh conditions achieved in this study, as the predominant sorbed Pu species in all conditions was expected to be the low-solubility and strongly sorbing Pu(OH) (sub 4) . Depending on the aquifer lithology, the occurrence of reducing conditions along a groundwater flowpath could potentially contribute to the retardation of redox-sensitive radionuclides (super 99) Tc and (super 237) Np, which are commonly identified as long-term dose contributors in the risk assessment in various radionuclide environmental contamination scenarios. The implications for increased sorption of (super 99) Tc and (super 237) Np to devitrified tuff under reducing conditions are significant as the fractured devitrified tuff serves as important water flow path at the NTS and the horizon for a proposed repository to store high-level nuclear waste at Yucca Mountain.

AN - 66694859; 19007169 AB - Abrine is an alkaloid chemical marker and surrogate analyte of abrin, a group of highly toxic glycoproteins. These toxins can be easily isolated from the seed of the rosary pea plant and distributed in a variety of matrices, including food. A procedure for the cleanup of abrine from various beverages, including milk, cola, juice drink, tea, and water, by C18 Strata-X solid-phase extraction (SPE) cartridges is described with comparison to a previously developed liquid-liquid extraction protocol utilizing acetonitrile and water. Analysis was by liquid chromatography/tandem mass spectrometry. Abrine quantitation was based on fragmentation of m/z 219.2 to product ion m/z 188.2. The method detection limit was 0.025 microg/mL, and the quantitation limit was 0.05 microg/mL. Fortifications of the five beverages at 0.5 and 0.05 microg/mL were recovered ranging from 88 to 111% [relative standard deviation (RSD) < 16%] by SPE and from 48 to 101% (RSD < 19%) by liquid-liquid extraction.

Equilibrium line altitudes (ELAs) interpreted from lateglacial to Early Holocene moraines indicate summertime cooling between nearly equal 3.9 and 6.6 degrees C relative to today's value, much less than the extreme Younger Dryas cooling registered by Greenland ice cores (mean-annual temperatures of nearly equal 15 degrees C colder than today's value). This apparent discrepancy between paleotemperature records supports the contention that Younger Dryas cooling was primarily a wintertime phenomenon. (super 10) Be ages of lateglacial and Holocene moraines show that mountain glaciers during the Little Ice Age were more extensive than at any other time since the Early Holocene Epoch. In addition, (super 10) Be ages of lateglacial moraines show extensive reworking of boulders with cosmogenic nuclides inherited from prior periods of exposure, consistent with our geomorphic observations and cosmogenic-exposure dating studies in other Arctic regions.

Alluvial fan and terrace incision was controlled partially by a drop in base level during the Pliocene or early Pleistocene as the outlet channel, the Draa river, progressively cut through the Anti-Atlas to the south of the Ouarzazate foreland basin, the drainage of which started to become external after a long period of internal drained conditions. The alluvial fans and terrace surfaces have abandonment ages that date to at least the past four glacial cycles. Their formation was strongly modulated by climate on glacial-interglacial time scales as base level dropped. This demonstrates a strong climatic control on sediment transfer and landscape denudation during the Quaternary and provides a model for understanding sediment transfer in other intracontinental mountain belts. Furthermore, these data show that mean rates of fluvial incision in this region range between 0.3 and 1.0 mm a (super -1) for the latter part of the Quaternary. This study provides the first comprehensive TCN chronology for the Atlas Mountains, and it illustrates the applicability and limitations of TCN methods.

These include a reduction in the amount of precipitation arriving as snow, a decline in snowpack at low and midelevations, and a shift toward earlier arrival of both snowmelt and the centroid (center of mass) of streamflows. To project future water supply reliability, it is crucial to obtain a better understanding of the underlying cause or causes for these changes. A regional warming is often posited as the cause of these changes without formal testing of different competitive explanations for the warming. In this study, a rigorous detection and attribution analysis is performed to determine the causes of the late winter/early spring changes in hydrologically relevant temperature variables over mountain ranges of the western United States. Natural internal climate variability, as estimated from two long control climate model simulations, is insufficient to explain the rapid increase in daily minimum and maximum temperatures, the sharp decline in frost days, and the rise in degree-days above 0 degree C (a simple proxy for temperature-driven snowmelt). These observed changes are also inconsistent with the model-predicted responses to variability in solar irradiance and volcanic activity. The observations are consistent with climate simulations that include the combined effects of anthropogenic greenhouse gases and aerosols. It is found that, for each temperature variable considered, an anthropogenic signal is identifiable in observational fields. The results are robust to uncertainties in model-estimated fingerprints and natural variability noise, to the choice of statistical downscaling method, and to various processing options in the detection and attribution method.
