TY - JOUR T1 - Analysis of thermohydrologic behavior for above-boiling and below-boiling thermal-operating modes for a repository at Yucca Mountain. AN - 73229848; 12714304 AB - We report results from a multi-scale thermohydrologic modeling study for two alternative thermal-operating modes for the potential repository system recently analyzed by the Yucca Mountain Project. These include a Higher-Temperature Operating Mode (HTOM), which results in a localized boiling zone around each emplacement drift, and a Lower-Temperature Operating Mode (LTOM), which always maintains sub-boiling temperatures throughout the repository. The HTOM places all waste packages nearly end to end, making the lineal power density greater than in the LTOM. The lower lineal power density in the LTOM was achieved by placing some waste packages farther apart (which results in a larger repository footprint), and through an increased reliance on pre-closure ventilation to remove the waste-package-generated heat. We focus on temperature T and relative humidity RH at the waste-package and drift-wall surfaces, and on in-drift evaporation. In general, HTOM temperatures are greater than corresponding LTOM temperatures, exhibit similar spatial variability and have a stronger dependence on infiltration flux. The duration of RH reduction on waste packages is similar for the LTOM and HTOM. A major difference between the LTOM and HTOM is the lower waste-package temperature at any given value of waste-package RH for the LTOM. Waste-package temperatures in the LTOM, by design, remain below approximately 85 degrees C; the absence of RH reduction arising from host-rock dryout causes waste-package RH to remain above about 40%. The HTOM waste packages experience higher temperatures and correspondingly lower RH conditions as a result of RH reduction arising from host-rock dryout. For most of the repository area, the HTOM delays the potential onset of gravity-driven seepage compared to the LTOM (as indicated by the duration of boiling at the drift wall). Boiling conditions in the HTOM also delays the onset of capillary-driven seepage into the granular invert, causing the HTOM to have less evaporation in the invert during the first 800-1500 years than the LTOM; subsequent evaporation rates are higher in the HTOM, due to the higher power density.

The Holocene sequence indicates a greater variability in circulation than previously detected. During the early Holocene, ca. 9 ka, B-P (super 14) C apparent age differences fluctuated between 220 and 560 (super 14) C yr, similar to rapid variations seen during the Younger Dryas and the last glacial episode. During the relatively stable middle Holocene (8.5-2 ka), B-P (super 14) C apparent age differences averaged 440 (super 14) C yr. After 2 ka, the average B-P (super 14) C apparent age difference increased to 620 (super 14) C yr, which has persisted until the present. The shift in B-P (super 14) C apparent age differences likely represents a change in the strength or source of North Pacific Intermediate Water production and is concurrent with changes in regional climate patterns as well as with changes in temperature and accumulation rates measured in the Greenland Ice Sheet Project 2 ice core, suggesting large-scale changes in atmospheric circulation patterns.

We combine the resulting mixing model with existing cosmogenic radionuclide methods that quantify river inputs and terrace ages to determine the major components of the long-term littoral sediment budget of the Santa Cruz, California, coastline. Sediment derived from coastal basins eroding at 0.2 mm/yr has a much lower concentration than sediment derived from 60-84 ka terrace sands atop backwearing seacliffs. The complex pattern of cosmogenic radionuclide concentrations in littoral sands along >100 km of coastline can be explained by mixing sediment derived from seacliffs backwearing at 10 cm/yr with that delivered by rivers having widely different amounts of sediment discharge.

Whereas active faults are present along most of the west side of the SEM, no active faults have been mapped at the surface on the east side where the erosional and depositional effects of the Colorado River have sculpted the range front. A series of at least four stepped strath terraces and an upper pediment surface are present along much of the eastern range flank. The strath and pediment surfaces all dip 1-2 degrees away from the range, and the differences in height between each terrace typically are 1 to 3 m. The strath terraces are cut into fine-grained fluvial-deltaic deposits and are capped by gravel deposits ( approximately 1 m thick). The fluvial-deltaic deposits probably formed when the Colorado River delta graded to the 125 ka Sangamonian high sea level stand at 7 m above present sea level (Carter, 1977). Given that these deposits are now approximately 20 m above the present floodplain, it is likely that approximately 13 m of uplift has occurred in this region since their deposition. The capping pediment and terrace gravels were dated using optically stimulated luminescence (OSL) and (super 10) Be cosmogenic radionuclide (CRN) depth-profile methods. The OSL ages range from approximately 20 to 28 ka, whereas the CRN ages scatter from 45 to 128 ka. We interpret the CRN ages to reflect inheritance due to exposure prior to final deposition and the OSL ages to represent the time of deposition of the capping gravels. Therefore, the formation and capping of the pediment and strath surfaces occurred 20-28 ka at a time when sea level was falling during the last glacial cycle. At this time, the Colorado River may have been entrenched immediately east of the SEM causing local base level to be 10's of meters lower. Sequential strath incision is interpreted to have occurred during this base-level lowering, but may have been punctuated by tectonic uplift. Since the time of high sea level deltaic deposition 125 ka, the deltaic deposits have been uplifted with average surface uplift rates of approximately 0.1 mm/yr. However, this rate may be higher if some of the high-stand fluvial-deltaic deposits were removed by erosion prior to pediment formation and/or if the pediment and strath surfaces graded to an entrenched Colorado River located just east of the SEM at 20-28 ka.

This monitoring activity is intended to establish the extent to which predicted behavior matches the actual response of the geological system to waste emplacement. To accomplish this goal, field measurements must be made at a spatial resolution that will determine whether the changes in parameters that are monitored conform to predicted evolutionary patterns. From the perspective of thermohydrological and geochemical parameters, key measurements will consider pore water compositional evolution and changes in matrix and fracture saturation in the near vicinity of waste emplacement tunnels. A massively parallel high performance computational platform (a 1200 processor IBM SP-2) was used to conduct three-dimensional, high resolution simulations to ascertain the spatial variability to be expected during a monitoring period. The results show that spatial variability in certain chemical parameters below waste emplacement tunnels provides robust targets for monitoring, but will require sampling on the scale of 10 s of centimeters in some locations, in order to rigorously test models. Chemical variability induced by relatively small changes in waste package heat output suggests that designing a monitoring program that will rigorously test model predictions will likely require high resolution, three-dimensional simulations of the 'as-built' monitoring tunnels.

Recharge of groundwater takes place through the vadose zone, where complex interactions between thermal-hydrological-geochemical processes affect water quality. Monitoring processes in the vadose zone is an important means of evaluating the long-term health of aquifer systems, and has become an integral part of many subsurface engineering efforts. Monitoring such systems, however, may be affected by changes in climate that slowly propagate through vadose zone systems. We describe in this paper the use of NUFT-C, a reactive transport simulator designed to run on a high performance, massively parallel computer, to compare quantitatively the evolution of a deep vadose zone with changes expected from an engineered high-level nuclear waste repository. The results suggest that the impacts from waste emplacement are, in some instances, similar to those that would be observed as a result of climate change, whereas others are distinguishable from evolution of the natural system. Such simulations facilitate design of long-term monitoring programs that take account of these complex effects. The results emphasize the importance of developing long-term baseline measurements and control sites, in order to enhance confidence in interpretations of complexly evolving data sets that will be obtained from multidecade monitoring efforts.

The validation of such numerical codes can be accomplished by comparison of numerical simulations against appropriate analytical solutions. In this paper, we present analytical solutions for the reactive transport of N-member radionuclide chains (i.e. multiple species of radionuclides and their daughter species) through a discrete fracture in a porous rock matrix applying a system decomposition approach. We consider the transport of N-member radionuclide chains in a single-fracture-matrix system as a starting point to simulate more realistic and complex systems. The processes considered are advection along the fracture, lateral diffusion in the matrix, radioactive decay of multiple radionuclides, and adsorption in both the fracture and matrix. Different retardation factors can be specified for the fracture and matrix. However, all species are assumed to share the same retardation factors for the fracture and matrix, respectively. Although a daughter species may penetrate farther along the fracture than its parent species when a constant- concentration boundary condition is applied, our results indicate that all species retain the same transport speed in the fracture if a pulse of the first species is released into the fracture. This solution scheme provides a way to validate numerical computer codes of radionuclide transport in fractured rock, such as those being used to assess the performance of a potential nuclear-waste repository at Yucca Mountain.

The most straightforward approach is to account for the 3-D drift- and mountain-scale dimensionality all within a single monolithic thermohydrologic model. This approach is too computationally expensive to be a viable simulation tool capable of addressing all waste-package locations in the repository. The Multiscale Thermohydrologic Model (MSTHM) is a computationally efficient alternative to addressing these modeling issues. In this paper, we describe the principal calculation stages to predict temperature, relative humidity, and liquid- saturation, as well as other thermohydrologic variables, in the drifts and in the host rock. Using a three-drift repository example (which is a scaled-down version of the proposed repository), we demonstrate the validity of the MSTHM approach against a nested monolithic thermohydrologic model.

The pCO (sub 2) was decreased by increasing Antarctic sea ice in a seven-box model of the world ocean, and another model showed a similar response to Southern Ocean stratification. In box models the pCO (sub 2) of the atmosphere is controlled by the region of the surface ocean that fills the deep sea By severing the Southern Ocean link between the deep sea and the atmosphere; atmospheric pCO (sub 2) in these models is controlled elsewhere and typically declines, although the models range widely in their responses. "Continuum models," such as three-dimensional (3-D) and 2-D general circulation models, control pCO2 in a more distributed way and do not exhibit box model sensitivity to high-latitude sea ice or presumably stratification.

New cosmogenic isotope measurements from upland bedrock surfaces and erratics along the northeastern margin of the Laurentide Ice Sheet (LIS) shed light on this debate. (super 10) Be and (super 26) Al concentrations from three perched erratics, yielding cosmogenic exposure ages of 17-11 ka, are much lower than those measured in two unmodified, highly weathered tors upon which they lie, which yield cosmogenic exposure ages of >60 ka. These findings suggest that non-erosive ice covered weathered upland surfaces along the northeastern margin of the LIS during the last glacial maximum. These data challenge the use of relative weathering to define the margins of Pleistocene ice sheets. The juxtaposition of non-erosive ice over upland plateaus and erosive ice in adjacent fiords requires strong gradients in basal thermal regimes, suggestive of an ice-stream mode of glaciation.

The process has been used to print coils on a variety of materials, including glass and Teflon. The dimensions of these coils can be varied easily to allow any number of different coil designs, including solenoids and saddle coils. In our fabrication process, capillary tubes sputter-coated with a thin titanium-copper multilayer are plated with a positive electrodeposited photoresist. The resist is exposed with a computer-controlled laser-lathe apparatus consisting of an argon-ion laser, an acousto-optic modulator, a movable aperture, a lead screw stage and a spindle stage. After exposure and development, copper is electrolytically deposited through the resist mask. Following copper deposition the resist mask is removed and the sputtered copper and titanium are etched away, leaving a microcoil firmly adhered to the capillary. The resistivity of the laser-lathe copper windings is 7.6% higher than the resistivity of hand-wound coils (1.85 mu Omega -cm for laser-lathe copper compared with 1.72 mu Omega -cm for bulk annealed copper). For laser-lathe and hand-wound microcoils of similar size and geometry, the coil quality factor, Q, of the laser patterned coils would be 7.6% lower than the hand-wound coils.

This study presents data collected from several investigations and indicates that B. anthracis virulence is associated with the clonality and virulence of plasmids pXO1 and pXO2. Guinea pigs vaccinated with Anthrax Vaccine Adsorbed were challenged with 20 B. anthracis isolates representative of worldwide genetic diversity. These same isolates were characterized with respect to plasmid copy number by using a novel method of quantitative PCR developed for rapid and efficient detection of B. anthracis from environmental samples. We found that the copy numbers for both pXO1 and pXO2 differed from those in previously published reports. By combining the data on survival, plasmid copy numbers, and clonality, we developed a model predicting virulence. This model was validated by using a randomly chosen set of 12 additional B. anthracis isolates. Results from this study will be helpful in future efforts to elucidate the basis for variation in the virulence of this important pathogen.

AN - 73167472; 12675491 AB - Benzene is both an environmental pollutant and a component of cigarette smoke, gasoline, and automotive emissions. Although occupational exposure to benzene has been shown to cause blood disorders and cancer in humans, the potential health effects resulting from exposure to low levels of benzene are not known. The goals of this project were to determine how well benzene is metabolized and to assess its binding to macromolecules in rodents at doses more closely mimicking human environmental exposure. To determine whether genotoxic metabolites of benzene are produced at environmental exposure levels. various doses of 14C-benzene were given intraperitoneally to male B6C3F1 mice at doses from 5 ng/kg to 500 mg/kg body weight. Samples of urine, plasma, liver, and bone marrow were taken at selected times up to 48 hours after exposure. Individual benzene metabolites in the samples were measured by accelerator mass spectrometry (AMS*). Metabolites were quantified by determining the area under the curve (AUC) for 24 to 48 hours. The major metabolites found in urine were an unidentified radiolabeled metabolite. phenyl sulfate, phenyl glucuronide. and muconic acid (an indicator of muconaldehyde formation). The major metabolites found in plasma, liver, and bone marrow samples were muconic acid and hydroquinone. Only liver showed a dose response for hydroquinone and muconic acid. The kinetics of both DNA and protein adduct formation were assessed over 48 hours at a 14C-benzene dose of 5 microg/kg body weight. A dose-response study was then conducted using 14C-benzene doses from 5 ng/kg to 500 mg/kg body weight in B6C3F1 mice. Adduct levels were determined by AMS in liver and bone marrow. DNA and protein adducts in liver reached maximum levels 30 minutes after benzene administration, whereas those in bone marrow reached maximum levels after six hours. Both protein and DNA adduct AUCs were greater in bone marrow than in liver. Dose-response assessments at both 1 and 12 hours showed that DNA and protein adducts in liver and bone marrow were dose dependent over doses spanning eight orders of magnitude. Consistent with the benzene metabolism data, these data show that reactive forms of benzene were present in liver and bone marrow after exposure to human-relevant benzene levels. Thus, at low doses, benzene was absorbed and metabolized into reactive intermediates capable of binding to DNA and protein. The relation between benzene metabolism and macromolecular binding was examined by comparing benzene macromolecular adduct formation among strains of male mice (B6C3F1, DBA/2, and C57BL/6) and male rats. These animals have been reported to have different metabolic capacities for benzene and also different tumorigenic and cytotoxic responses to benzene exposure. We hypothesized that differences in the capacity to metabolize benzene affect macromolecular adduct formation and that the amount of macromolecular damage is related to benzene's ability to cause cancer and other blood disorders. 14C-benzene was administered intraperitoneally to all rodents (5 microg/kg body weight) and adduct levels were determined by AMS at selected time points up to 48 hours after exposure. AUCs for protein and DNA adducts in bone marrow, the primary target organ for benzene toxicity, decreased in the following order: B6C3F1, DBA/2, C57BL/6, and rats. Similarly, adduct AUCs in liver were greater in B6C3F1 mice than in rats although the trend was less clear for the DBA/2 and C57BL/6 mouse strains. The results of this work are consistent with previously published work showing that the ability to metabolize benzene follows a similar pattern with these animals and is consistent with the tumorigenicity of benzene in mice and rats. Thus, our data suggest that benzene toxicity is related to the ability to produce macromolecular adducts. Preliminary studies were conducted to assess adduct dosimetry after low-dose inhalation of benzene. Inhalation methods were developed to administer a nominal body burden of 5 microg benzene/kg body weight. Then, 14C-benzene was administered to B6C3F1 mice and rats by both intraperitoneal (IP) administration and by inhalation, and DNA and protein adducts in liver and bone marrow were analyzed by AMS. AUCs for adduct levels were greater after IP benzene administration than after inhalation of benzene. Adduct levels were greater in DNA from B6C3F1 mouse bone marrow than in DNA from liver regardless of exposure route. Collectively, these data show that the internally reactive dose was greater when benzene exposure was by IP administration. In summary, the results suggest that benzene is metabolized to reactive forms capable of binding both protein and DNA in target and nontarget organs of rats and mice at doses encountered by humans through environmental exposure. Macromolecular binding was dose-dependent at low doses of benzene and reflected benzene toxicity, based on its carcinogenicity and ability to cause other blood-related disorders. These data are consistent with macromolecular adducts being indicative of benzene exposure and benzene toxicity although much more research is needed to validate this point. Additionally, benzene metabolism varies among species and among strains within a species of rodent. Thus data are needed in humans to understand how to use the rodent data in risk assessment and ultimately to determine whether macromolecular adducts are a useful indicator of exposure and a useful predictor of risk.

Results suggest spatially homogeneous sediment generation (on the 10 (super 4) -10 (super 5) yr time scale and >100 km (super 2) spatial scale) at 73+ or -11 t km (super -2) yr (super -1) , equivalent to 27+ or -4 m/m.y. of bedrock erosion. This rate is consistent with rates derived from fission-track, long-term sediment budget, and sediment yield data, all of which indicate that the Great Smoky Mountains and the southern Appalachians eroded during the Mesozoic and Cenozoic at approximately 30 m/m.y. In contrast, unroofing rates during the Paleozoic orogenic events that formed the Appalachian Mountains were higher (> or =10 (super 2) m/m.y.). Erosion rates decreased after termination of tectonically driven uplift, enabling the survival of this ancient mountain belt with its deep crustal root as an isostatically maintained feature in the contemporary landscape.

By using multiple backhoe trenches and radiocarbon dating of wood and charcoal, we determined the history of five small fans (1900-14,850 m (super 3) ) that range in age from historic to > or =13,320 calibrated (cal.) (super 14) C yr B.P. Three fans located on river terraces have depositional records whose ages are limited by the age of the terrace on which they are situated. Two other fans, located in glacial valleys, preserve records that extend back nearly to deglaciation. The stratigraphy of all five fans contains evidence suggesting episodic activity, including scoured surfaces and layers of gravel and cobbles. Periods of little or no activity are indicated by development of now-buried soils. Dated sand and gravel strata in several fans suggest correlative periods of increased sediment yield and by inference, runoff, at ca. 9650-9340 and 6900-6020 cal. (super 14) C yr B.P. Soils preserved within at least two of the five fans suggest lower sediment yield at ca. 12,900, ca. 5500, ca. 4300, and ca. 3200 cal. (super 14) C yr B.P. At least three of the fans aggraded rapidly during the past several hundred years in response to land clearance and disturbance; however, many aggradation and scour events in the Holocene cannot be correlated definitively between fans because of the discontinuous nature of gravel beds and the lack of radiocarbon-datable material in the coarsest strata. Drainage-basin sediment yields implied by the fan volumes and integrated over the Holocene are quite low, > or =4-11X10 (super 3) kg.km (super -2) .yr (super -1) . Sediment yields since settlement by European and other immigrants are several to hundreds of times higher, demonstrating the connections among forest clearance, agriculture, and increased erosion rates of New England hillslopes.

The seismic reflections were excited by a drill bit moving along a horizontal well at a depth of 2800 m. The data were recorded by a receiver array on the surface. There were 609 twenty-second traces recorded at each of 10 three-component stations. After preprocessing, the traces were autocorrelated and migrated. Two imaging conditions were examined. The ghost-reflection imaging condition produced a reflectivity section that agreed with a nearby common-depth-point section. The migration section obtained with a primary-reflection imaging condition produced a reflectivity section inferior in quality to that of the ghost image. A possible explanation is that the drill-bit location was not precisely known, which can be shown to induce weak errors in the ghost-imaging condition but stronger errors in the primary-reflection imaging condition. Ghost migration images reflections not only below the drill bit, but also above the drill bit. This investigation is one of the first examples of successfully imaging the earth's reflectivity section from horizontal drill-bit data, and it offers a potentially useful method for seismic imaging from drill-bit data.

The results of applying this method yield source spectra that are more stable than any other direct-phase measure to date. The procedure accounts for all propagation, site, and S-to-coda transfer function effects. The resultant coda-derived moment-rate spectra are then used to provide traditional band-limited magnitudes (e.g., M (sub L) , m (sub b) ), as well as an unbiased, unsaturated magnitude (moment magnitude, M (sub w) ) that is tied to a physical measure of earthquake size (i.e., seismic moment). We validate our results by comparing our coda-derived moment estimates with those obtained from long-period waveform modeling. Most importantly, we demonstrate that the interstation magnitude scatter is significantly reduced when using long-window-length coda (i.e., M (sub w) (coda) and m (sub b) (coda)). However, when we use short-window coda measurements of 5 sec in length taken after twice the direct-wave travel time, the scatter remains large, comparable to direct waves. Once calibrated, the coda-derived source spectra provide stable, unbiased magnitude estimates for events that are too small either to be reliably waveform modeled or to be seen at far-regional and teleseismic distances. This property is ideal for sparse local or regional networks. We found that our source amplitude estimates were nearly insensitive to the expected source radiation pattern and exhibited roughly a factor of 3-5 less interstation scatter when compared against coda duration and conventional direct-phase measurements (e.g., P (sub g) , L (sub g) ). We also found that the coda stability, as measured by the interstation scatter for common events, reached a minimum value beyond a certain critical measurement window length. For example, at 6-8 Hz, the interstation standard deviation was less than 0.08 provided the coda measurement was at least approximately 80 sec in duration, whereas at 1.5-2.0 Hz, the critical window length was approximately 100 sec. For all frequency bands, as the coda window becomes shorter, the standard deviation increases, asymptotically approaching the direct-wave scatter. In this article we describe in detail the calibration methodology and address concerns related to choosing optimal measurement window lengths, estimating error, testing empirical path corrections, and tying coda amplitudes to an absolute scale. In order to demonstrate the usefulness and transportability of our method, we chose the Dead Sea Rift as our study area.

In source areas, located in the immediate vicinity of the contaminant releases, the contaminants are distributed in relatively high concentrations throughout the vadose zone and below the water table in both fine-grained and coarse-grained sediments. In distal portions of the plume, downgradient of the source areas, the contaminants: 1) are primarily limited to coarse-grained zones, 2) are usually orders of magnitude lower in concentration than in the source areas, and 3) have slightly diffused into the bordering aquitards but should not significantly affect the approach to or achievement of cleanup goals. The cleanup strategy for this distribution of contaminants calls for the hydraulic isolation of the source area followed by aggressive remediation of both the source and distal areas of the plume as needed to achieve remediation objectives most efficiently. In contrast to some of the currently perceived limitations of pump-and-treat remediation, our data and analyses indicate that distal portions of contaminant plumes can be expeditiously remediated, perhaps in less time than it took the contaminants to be transported to their preremediation locations.

Recently, the procedures used by the group at the Australian National University (ANU) for the hydro-isostatic component of the theory have been questioned (Quat. Sci. Rev. 21 (2002) 409) although the details of the ANU group's procedures have not been published because they are mainly computational in nature rather than representing significant conceptual advances. Because of this criticism, we set out here in detail the procedures that have been used for the treatment of the migration of shorelines as sea levels rise and fall, the effect of retreat and advancing grounded ice on shelves and shallow seas, and the transitions from grounded to floating ice (and vice versa). We conclude that there is no basis for the criticism, that these formulations and their implementation provide a high resolution and complete description of both sea-level change and of the estimates of volumes of ice exchanged with the oceans. The results from this formulation are confirmed by the entirely independent analyses of Milne et al. (Quat. Sci. Rev. 21 (2002) 361) and Mitrovica and Milne (Geophys. J. Int. (2002), submitted for publication) who conclude that our formulation is significantly more accurate than the procedure advocated by Peltier (Science 265 (1994) 195; Rev. Geophys. 36 (1998a) 603, Geophys. Res. Lett. 25 (1998b) 3955).

This process is notoriously difficult to model, given the complexity of the turbulent boundary layer and chemistry of the three-phase interface (air, liquid, solid) typically found at the land surface. Wind tunnel studies have demonstrated the importance of resuspension within a short time after deposition, but there exists no robust model for short-term resuspension. Numerical simulations of accidental or terrorist releases of hazardous materials need such a model to accurately predict fate and transport of the materials within hours to days after release. Many accepted conventional models were derived from resuspension data for aged sources, such as former weapons test sites; these data sets, and the associated models, may not be appropriate for short-time resuspension. The study described here reexamined historical wind tunnel data on short-term resuspension, with the goal of developing a model appropriate for numerical simulations. Empirical models are derived from these data using a suite of parameters (friction velocity, particle diameter, surface roughness, particle density, and time). These empirical models, and the wind tunnel data, are compared quantitatively with existing conventional models from the literature. The conventional models underpredict short-time resuspension, resulting in order-of-magnitude errors in predictions of resuspended mass. Only three models perform reasonably well: the empirical models derived from the data and an adaptation of the NCRP 129 model.

Our work will help to lower operating costs through improved scale prediction and add new revenue streams from sale of mineral byproducts extracted from geothermal fluids. Improving the economics and effectiveness of scale control programs and/or extraction systems in geothermal operations requires a coupled kinetic-thermodynamic model of silica behavior. Silica scale precipitation is a multi-step process, involving a nucleation-related induction period, aqueous polymerization, condensation of polymers to form colloids, and deposition onto a solid surface. Many chemical and physical variables influence the rates of these steps and their impacts must be quantified and predictable in order to optimally control silica behavior. To date, in laboratory studies, we have quantified the effects on silica polymerization of the following set of chemical variables: Na at 500 and 2000 ppm, pH values from 5 to 9, temperatures of 25 and 50 degrees C, and silica saturation values from 1.2 to 6 at initial dissolved silica concentrations of 600 ppm. Lowering pH both increases the induction time prior to polymerization and decreases the polymerization rate. We have successfully used a multiple regression model to predict polymerization rates from these variables. Geothermal fluids contain significant dissolved concentrations of potentially valuable mineral resources such as zinc, lithium, cesium and rubidium, but silica fouling interferes with traditional extraction methods. We are developing customized and new technologies to extract the silica as a commercial-grade commodity as well as the valuable metals. We are conducting field testing of some of these techniques at a Mammoth, CA geothermal plant using a reverse osmosis unit to concentrate the fluid, adding a commercial agglomerating agent to promote silica precipitation, and then removing the silica using a tangential flow ultrafilter. The particle size, surface area and trace impurities of the silica are characterized for comparison with commercial-grade silica products. We are also testing ion exchange resins and other functionalized materials to extract potentially economic concentrations of lithium, cesium, and rubidium that are enriched in the reverse osmosis concentrate.

Analysis of this data set reveal that several outcrops of these altered minerals exist in the area, and that one outcrop, roughly 1 square kilometer in area, shows abundant high temperature alteration. Structural analysis of the altered region using a Digital Elevation Model (DEM) suggests that this outcrop is bounded on all sides by a set of cross-cutting faults. This fault set lies within the Dixie Valley Fault system (Caskey et al. 1996). Both the intense alteration in this area and the presence of cross-cutting faults indicate a high probability of recent hot fluid escape.

In fractured samples, phase change (vaporization/condensation) can result in resistivity changes that are more than an order of magnitude greater than those measured in intact samples. These results suggest that electrical resistivity monitoring of geothermal reservoirs may provide a useful tool for remotely detecting the movement of water and steam within fractures, the development and evolution of fracture systems and the formation of steam caps. We measured the electrical resistivity of cores of welded tuff containing fractures of various geometries to investigate the resistivity contrast caused by active boiling and to determine the effects of variable fracture dimensions and surface area on water extraction from the matrix. We then used the Nonisothermal Unsaturated Flow and Transport model (NUFT) (Nitao, 1998) to simulate the propagation of boiling fronts through the samples. The simulated saturation profiles combined with previously reported measurements of resistivity-saturation curves allow us to estimate the evolution of the sample resistivity as the boiling front propagates into the rock matrix. These simulations provide qualitative agreement with experimental measurements suggesting that our modeling approach may be used to estimate resistivity changes induced by boiling in more complex systems.

S. Basin and Range with a focus on Dixie Meadows, Nevada AN - 881449919; 2011-065452 AB - This paper presents an overview of the work our collaboration is doing to increase the detailed mapped resource base for geothermal exploration in the Western US. We are imaging several large areas in the western US with high resolution airborne hyperspectral and satellite multispectral sensors. We have now entered the phase where the remote sensing techniques and tools we are developing are mature enough to be combined with other geothermal exploration techniques such as aeromagnetic, seismic, well logging and coring data. The imaging sensors and analysis techniques we have developed give us the ability to map visible faults, surface effluents, altered minerals, and subtle hidden faults. Large regions are being imaged at reasonable costs. The technique of geobotanical remote sensing for geothermal signatures is based on recent successes in mapping hidden faults, high temperature altered mineralization, clays, hot and cold springs and CO2 effluents the Long Valley Caldera and Mammoth Mountain in California. The areas that have been imaged include Mammoth Mountain and the Long Valley Caldera, Dixie Meadows NV, Fish Lake Valley NV, and Brady Hot Springs. Areas that are being imaged in the summer of 2003 are the south moat of the Long Valley Caldera, Mammoth Mountain western flanks, Mono Inyo chain north of Mammoth Mountain in CA, and the Humboldt Block in NV. This paper focuses on presenting the overview of the high-resolution airborne hyperspectral image acquisition that was done at Dixie Meadows NV in August 2002. This new imagery is currently being analyzed and combined with other field data by all of the authors on this paper. Results of their work up until June 23, 2003 are presented in other papers in the this volume, and their results up until the time of the conference will be presented in the remote sensing session on Tuesday morning.

AN - 72957025; 12526008 AB - The aim of this study was to determine the chemical structure of in vitro 2-amino-1-methyl-6-phenylimidazo[4,5-b]pyridine (PhIP)-modified oligodeoxynucleotides (ODNs) by exonuclease digestion and matrix-assisted laser desorption/ionization mass spectrometry. A single-stranded 11-mer ODN, 5'-d(CCATCGCTACC), was reacted with N-acetoxy-PhIP, resulting in the formation of one major and eight minor PhIP-ODN adducts. A 10 min treatment of the major and one minor PhIP-ODN adduct with a 3'-exonuclease, bovine intestinal mucosa phosphodiesterase (BIMP), and a 5'-exonuclease, bovine spleen phosphodiesterase, results in inhibition of the primary exonuclease activity at deoxyguanosine (dG) producing 5'-d(CCATCG(PhIP)) and 5'-d(G(PhIP)CTACC) product ions, respectively. Post-source decay (PSD) of these enzymatic end products identifies dG as the sole modification site in two 11-mer ODN-PhIP adducts. PSD of the minor PhIP-ODN adduct digestion end product, 5'-d(CCATCG(PhIP)), also reveals that the PhIP adducted guanine moiety is in an oxidized form. Prolonged treatment of the PhIP-ODN adducts at 37 degrees C with BIMP induces a non-specific, or endonuclease, enzymatic activity culminating in the formation of deoxyguanosine 5'-monophosphate-PhIP (5'-dGMP-PhIP). The PSD fragmentation pattern of the 5'-dGMP-PhIP [M + H](+) ion of the major adduct confirms PhIP binds to the C-8 position of dG. For the minor adduct, PSD results suggest that PhIP binds to the C-8 position of an oxidized guanine, supporting the hypothesis that this adduct arises from oxidative degradation, resulting in a spirobisguanidino structure.

AN - 72955845; 12517776 AB - The objective of this research was to determine whether Novantrone, Oncovin, Velban, and Prednisone (NOVP) combination chemotherapy for Hodgkin's disease increases the frequencies of the specific types of aneuploid sperm that might elevate the risk of fathering a child with one of the major clinical aneuploidy syndromes, i.e., Down (disomy 21 sperm), Edward (disomy 18 sperm), Turner (nullisomy sex sperm), XYY (disomy Y sperm), triple X (disomy X sperm), or Klinefelter (XY sperm). A four-chromosome multicolor sperm fluorescence in-situ hybridization assay that simultaneously evaluates chromosomes 18, 21, X, and Y was applied to semen provided by four healthy men and to repeated samples of eight Hodgkin's disease patients before treatment, 35-50 days after treatment to examine the effects of treatment on male meiotic cells, and 1-2 years after treatment to measure the persistence of damage. There were chromosome-specific variations in baseline frequencies and significant inductions of all of the detectable types of sperm aneuploidies: XY sperm (14-fold increase), disomy 18 (7-fold), nullisomy sex (3-fold), disomy 21 (3-fold), and disomy X and Y (approximately 2-fold each). Disomy 21 was about twice as frequent as disomy 18, and neither showed a preferential segregation with a sex chromosome. Extrapolating across the genome, approximately 18% of sperm carried a numerical abnormality after NOVP treatment of meiotic cells. Induced effects did not persist to 1-2 years after treatment, suggesting that persistent spermatogonial stem cells were not sensitive to NOVP. These findings establish the hypothesis that conception shortly after certain chemotherapies can transiently increase the risks of fathering aneuploid pregnancies that terminate during development or result in the birth of children with major human aneuploidy syndromes.

AN - 71475748; 14690798 AB - We conducted a study to evaluate dietary chemopreventive strategies to reduce genotoxic effects of the carcinogens 2-amino-1-methyl-6-phenyl-imidazo[4,5-b]pyridine (PhIP) and 2-amino-3-methylimidazo[4,5-f]quinoline (IQ). PhIP and IQ are heterocyclic amines (HCAs) that are found in cooked meat and may be risk factors for cancer. Typical chemoprevention studies have used carcinogen doses many thousand-fold higher than usual human daily intake. Therefore, we administered a low dose of [14C]PhIP and [3H]IQ and utilized accelerator mass spectrometry to quantify PhIP adducts in the liver, colon, prostate, and blood plasma and IQ adducts in the liver and blood plasma with high sensitivity. Diets supplemented with phenethylisothiocyanate (PEITC), genistein, chlorophyllin, or lycopene were evaluated for their ability to decrease adduct formation of [14C]PhIP and [3H]IQ in rats. We also examined the effect of treatments on the activity of the phase II detoxification enzymes glutathione S-transferase (GST), UDP-glucuronyltransferase (UGT), phenol sulfotransferase (SULT) and quinone reductase (QR). PEITC and chlorophyllin significantly decreased PhIP-DNA adduct levels in all tissues examined, which was reflected by similar changes in PhIP binding to albumin in the blood. In contrast, genistein and lycopene tended to increase PhIP adduct levels. The treatments did not significantly alter the level of IQ-DNA or -protein adducts in the liver. With the exception of lycopene, the treatments had some effect on the activity of one or more hepatic phase II detoxification enzymes. We conclude that PEITC and chlorophyllin are protective of PhIP-induced genotoxicity after a low exposure dose of carcinogen, possibly through modification of HCA metabolism.

Glass starting powders enriched in (super 18) O and (super 28) Si were mated to isotopically normal glass powders to form simple diffusion couples, and self-diffusion experiments were conducted in the piston cylinder device (1 and 2 GPa) and in the multianvil apparatus (3.5 and 4 GPa). Profiles of (super 18) O/ (super 16) O and (super 29,30) Si/ (super 28) Si were measured using secondary ion mass spectrometry. Self-diffusion coefficients for O (D(O)) are slightly greater than self-diffusion coefficients for Si (D(Si)) and are often the same within error. For example, D(O) = 4.20+ or -0.42X10 (super -11) m (super 2) /s and D(Si) = 3.65+ or -0.37X10 (super -11) m (super 2) /s at 1 GPa and 1662 degrees C. Activation energies for self-diffusion are 215+ or -13 kJ/mol for O and 227+ or -13 kJ/mol for Si. Activation volumes for self-diffusion are -2.1+ or -0.4 cm (super 3) /mol and -2.3+ or -0.4 cm (super 3) /mol for O and Si, respectively. The similar self-diffusion coefficients for Si and O, similar activation energies, and small, negative activation volumes are consistent with Si and O transport by a cooperative diffusion mechanism, most likely involving the formation and disassociation of a high-coordinated intermediate species. The small absolute magnitudes of the activation volumes imply that Di (sub 58) An (sub 42) liquid is close to a transition from negative to positive activation volume, and Adam-Gibbs theory suggests that this transition is linked to the existence of a critical fraction ( approximately 0.6) of bridging oxygen.

A comparison of (super 10) Be, (super 26) Al, and (super 41) Ca concentrations with calculated production rates from two different models indicates that the Gold Basin samples came from depths of about 10 cm to more than 150 cm in an object with a radius of 3-5 m. As was predicted by recent model calculations, the noble gases show a reversal of the (super 22) Ne/ (super 21) Ne ratio at very high shielding. The (super 21) Ne/ (super 10) Be and (super 21) Ne/ (super 26) Al ratios in most samples are constant and correspond to a 4pi exposure age of 18+ or -2 Myr. However, three Gold Basin samples show a 30-120% excess of (super 21) Ne implying that they were previously exposed close to the surface of the parent body, whereas the other samples were buried several meters deeper. Concentrations of neutron-capture (super 36) Ar in most samples are consistent with measured concentrations of neutron-capture (super 36) Cl and an exposure age of 18 Myr. Large excesses of neutron-capture (super 36) Ar were found in those samples with an excess of (super 21) Ne, providing additional evidence of a first-stage exposure on the parent body. The excess of spallation-produced (super 21) Ne and neutron-capture-produced (super 36) Ar in these samples indicate a first-stage exposure of 35-150 Myr on the parent body. The radiogenic (super 4) He and (super 40) Ar concentrations indicate a major impact on the parent body between 300 and 400 Myr ago, which must have preceded the impacts that brought the Gold Basin meteoroid to the surface of the parent body and then expelled it from the parent body 18 Myr ago.

The glacial geologic evidence and the CRN dating show that glaciers existed in this marginal region of Tibet during the latter part of the global Last Glacial Maximum and during the Lateglacial. These data suggest that temperatures were low enough and/or monsoon precipitation was sufficiently high to support one or more limited glacial advances between approximately 20 and 10 ka. Nevertheless glaciation was limited to glaciers of <10 km in length and the estimated ELA depression was approximately 800 m. These results confirm studies throughout other regions of Tibet and the Himalaya that show that glaciation was restricted during the latter part of the Last Glacial.

However both of these are topics of much debate, mainly due to the paucity of reliable, uninterrupted, regionally-representative proxy records back through the last glacial maximum (LGM). Reconstructions are often highly-localised and based on qualitative indicators of change. However material collected from the Amazon Fan allows us to examine an average signal of the whole of the Amazon Basin within a single sedimentary sequence. Here, we present data collected from ODP Site 942 and reveal that the Amazon Basin was forested yet relatively dry during the last glacial stage. Analysis of carbon isotopes on terrestrial biomarkers reveal that there has been relatively little shift in the C3:C4 ratio of the vegetation over the last 40 ka. Quantitative reconstructions of effective moisture based upon oxygen isotope analysis of planktonic foraminifera, suggest a significant reduction in the Amazon River outflow during both the LGM and last glacial-interglacial transition. We provide further evidence for glacial aridity through a quantified reconstruction of the fire history of the Amazon Basin, where fire-specific biomarkers are of coincident increased abundance throughout the more arid periods. We thereby refute the suggestion of encroaching savannah vegetation during glacial times, yet support the concept of a drier, cooler glacial Amazon Basin.

Pleistocene Lake levels are recorded in wave-cut terraces and lake-deposited tufas above the modern shoreline, but the Holocene climate record is preserved primarily in the sedimentary record. Pyramid Lake receives the majority of its input from the Truckee River, which heads in the Sierra Nevada. It is the only large closed-basin lake in the western Great Basin to have escaped desiccation during the Holocene. For this reason, it is an ideal site for reconstructing Holocene climate change. Three sediment cores spanning the last 7500 calendar years before present (cal yr BP) were analyzed for pollen at decadal to century-scale resolution. Dry periods were defined using the ratio of Chenopodiaceae (saltbush) pollen to Artemisia (sagebrush). This ratio suggests that the mid-Holocene (7500 - 6300 cal yr B.P.) was the warmest and driest portion of the record. Pyramid Lake was greatly reduced in size and the surface of Lake Tahoe was approximately 4 m below its modern elevation. Dry conditions persisted until approximately 5000 cal yr B.P. at which time there was a gradual but erratic increase in precipitation that continued as a generally wetter climate through 3500 cal yr B.P. A return to very dry conditions is seen between 2500 and 1800 years B.P. The last 1800 years have seen repeated wet-dry cycles, however none of the dry periods were as intense as those occurring during earlier periods. The record supports the evidence for prolonged droughts centered at approximately 800 and approximately 600 cal yr BP identified from submerged stumps at Mono Lake. The drought record reconstructed from fossil pollen correlates with the high-resolution record of multidecadal and multicentennial droughts identified in the oxygen isotope record from Pyramid Lake and compares favorably with other proxy records from the Great Basin. The timing of major shifts in climate also corresponds to the timing of rapid changes in drift-ice accumulation identified in the North Atlantic. These changes have been documented to coincide with changes in solar output. Our results imply that similar mechanisms may be responsible for Great Basin Holocene climate changes.

Precise Pliocene-Quaternary fan chronologies in arid regions are necessary for calculating strain rates and seismicity recurrence intervals. Soils geomorphology and cosmogenic 10Be in quartz on alluvium in the U.S. southwest (Providence Mtns., Fish Lake Valley, and Amargosa Valley) reveal that it is not always possible to attain high precision fan chronologies. Examination of alluvial fan sediments and surfaces from four lithologically distinct catchments in the Providence Mtns (eastern California) indicates that although fan aggradation is approximately synchronous around 75+ or -10 ka (QF3 fans), older and younger fans correlated along the same range front do not show this synchronicity. Instead of invoking geomorphological explanations of the exposure age disparities among correlative fans, we turned to the assumptions of the dating method. For the Mojave region, the 75-kyr aggradation event may be the most optimally suited for exposure dating. Older fans have significantly and variably disturbed surfaces (erosion, mixing, and burial also vary with elevation), so exposure ages (from surface boulders and subsurface and pavement pebbles) of correlated fans will vary. Large changes in bulk densities during pedogenesis also need to be considered. For younger fans, inheritance is the dominating control on the ages. In the Providence Mtns. and Amargosa Valley (western Nevada), modern wash sediment has as much as 70-kyr worth of inherited 10Be. Even with concentration-depth profiles using amalgamated pebble samples it is not possible to estimate this amount of inheritance with sufficient accuracy to correct a Holocene fan exposure age. The influence of inheritance diminishes with depositional age of a fan. Furthermore, when the option exists, we suggest choosing fans from rapidly eroding or previously glaciated catchments for dating, and correlating other fans along a range front with soils. Ages on a Holocene fan emanating from a glaciated catchment in Fish Lake Valley show lower standard deviations and are closer to radiocarbon ages than ages on a correlated radiocarbon-dated fan from a non-glaciated adjacent catchment.

Based on previous detailed dose assessments for Bikini, Enewetak, Rongelap, and Utirik Atolls over a period of 28 years, cesium-137 ( (super 137) Cs) at Bikini Atoll contributes about 85-89% of the total estimated dose through the terrestrial food chain as a result of uptake of (super 137) Cs by food crops. The estimated integral 30, 50, and 70-year doses were based on the radiological decay of (super 137) Cs (30-year half-life) and other radionuclides. However, there is a continuing inventory of (super 137) Cs and (super 90) Sr in the fresh water portion of the groundwater at all contaminated atolls even though the turnover rate of the fresh groundwater is about 5 years. This is evidence that a portion of the soluble fraction of (super 137) Cs and (super 90) Sr inventory in the soil is lost by transport to groundwater when rainfall is heavy enough to cause recharge of the lens, resulting in loss of (super 137) Cs from the soil column and root zone of the plants. This loss is in addition to that caused by radioactive decay. The effective rate of loss was determined by two methods: (1) indirectly, from time-dependent studies of the (super 137) Cs concentration in leaves of Pisonia grandis, Guettarda specosia, Tournefortia argentea (also called Messerschmidia), Scaevola taccada, and fruit from Pandanus and coconut trees (Cocos nucifera L.), and (2) more directly, by evaluating the (super 137) Cs/ (super 90) Sr ratios at Bikini Atoll. The mean (and its lower and upper 95% confidence limits) for effective half-life and for environmental-loss half-life (ELH) based on all the trees studied on Rongelap, Bikini, and Enewetak Atolls are 8.5 years (8.0 years, 9.8 years), and 12 years (11 years, 15 years), respectively. The ELH based on the (super 137) Cs/ (super 90) Sr ratios in soil in 1987 relative to the (super 137) Cs/ (super 90) Sr ratios at the time of deposition in 1954 is less than 17 years. The magnitude of the decrease below 17 years depends on the ELH for (super 90) Sr that is currently unknown, but some loss of (super 90) Sr does occur along with (super 137) Cs. If the 15-year upper 95% confidence limit on ELH (corresponding to an effective half-life of 9.8 years) is incorporated into dose calculations projected over periods of 30, 50, or 70 years, then corresponding integral doses are 58, 46 and 41%, respectively, of those previously calculated based solely on radiological decay of (super 137) Cs.

N1 - Date revised - 2004-01-01 N1 - Last updated - 2012-06-07 ER - TY - JOUR T1 - Early human remains from Bano Nuevo-1 Cave, central Patagonian Andes, Chile AN - 51826132; 2004-053868 AB - The notable sparseness of human skeletal remains is a characteristic trait of early American prehistory, and, therefore, this aspect of the archaeological record is seldom considered in its discussion. In this context, the finding of remains from five individuals dated to the 9th millenium BP on the re-excavations at Bano Nuevo Cave (Andean Central Patagonia, Chile) is particularly interesting. They may not appear excessively old, but several radiocarbon dates (two of them done through AMS directly on the bone of one of the individuals) place them among the very few well-dated early human skeletons throughout the Americas. The small sample size militates against any interpretation of biological affiliation (to say nothing of population movements) and we can only affirm that these people belonged to a generalized "mongoloid stock", different from historically known Patagonian populations. After a brief presentation of the skeletal evidence and the bone dating methods, we evaluate the relevance of this context with respect to the sparse osteological record of humans in the Americas on the Pleistocene/Holocene transition.

The study makes use of data recorded during nuclear explosions at the Nevada Test Site, at several stations across the Las Vegas basin. Data from two stations located near rock on opposite edges of the basin were deconvolved for use as input to project surface motions at two deep-basin sites. The soil models for the deep basin sites were constructed using relevant geotechnical borehole information and lithologic well logs. Shear wave velocity profiles for individual sites were developed from a combination of seismic test results including downhole, crosshole, SASW, ReMi and refraction. Small-strain damping and strain-dependent dynamic soil properties were inferred from published literature. Appropriate depth to halfspace was selected according to the criterion that projected peak ground acceleration should match the measured value. Site-specific amplification of the two soil sites, subjected to the two different base motions, was calculated. Comparisons of projected ground motions with measured motions showed that alluvial deposits are significant contributors to small-strain seismic response of the Las Vegas basin in the frequency band 0.8 to 15 Hz. The one-dimensional model captured important ground motion features such as peak ground acceleration and maximum spectral acceleration. Appropriate depth to model halfspace is considerably less than the depth to bedrock. High-velocity cemented inclusions should be explicitly accounted for in the soil profile.

The goal is to identify and locate rockfall events remotely using automated data collecting and processing techniques. We will install seismometers on the ground surface, generate seismic energy to simulate rockfall in underground space beneath the array, and interpret the surface response to discriminate and locate the event. Data will be analyzed using matched-field processing, a generalized beamforming method for localizing discrete signals. Software is being developed to facilitate the processing. To date, a three-component sub-array has been installed and successfully tested.

The targeted application for this research is ensuring the long-term stability of the underground openings of the proposed repository for high-level nuclear waste at Yucca Mountain. To this end, we are installing six seismometers on the ground surface above existing underground passages. The seismic array, including seismometers, data acquisition system, and preliminary data visualization and reduction, will be tested using simulated rockfall. Data acquired during the tests will be analyzed using concepts of matched-field waveform processing to explore the feasibility of the passive seismic monitoring concept to locate rockfall events. To date, a three-component sub-array has been installed and a preliminary test has been performed. In the preliminary test, seismic energy was supplied by hammering on rock bolts in the Yucca Mountain Exploratory Studies Facility (ESF) alcoves and train operation within the ESF. Data were acquired underground and with the surface sub-array. The results of the preliminary test indicate that the equipment is working properly and that seismic signals produced within the ESF can be recorded on the surface. Simulated rockfall tests, currently in preparation stages, will be performed using dropped weights.

Individual analyses ranged from 18,090-18,245 yr BP with reported errors between 30-50 yr. The weighted average fraction modern (FM) of these 28 measurements is 0.10378 + or - 0.00008 (which equates to 18,199 + or - 8 yr BP) and the measurements show a 1 standard deviation scatter of 0.00044 (+ or -35 yr). The fractional error of these results indicates reproducibility of individual measurements at the 4 per mil (1sigma ) level, which is consistent with the quoted counting-statistics-based errors. Laboratories engaged in the determination of (super 14) C results at reasonably high precision should consider taking advantage of the TIRI and FIRI sample materials in the role of process standards.

EQ3/6 was used to model alteration scenarios with available kinetic data. Calculation predictions were tested in four experiments to determine if carbonate minerals would form under specific laboratory conditions as predicted by calculation. Each experiment used Dickson-type rocking gold bag autoclaves running for 3 to 5 months with 75-100 Am-sized An (sub 60) plagioclase grains at 150 degrees C and pressures of 100 bars. Variables include initial CO (sub 2) fugacity (from 0.15 to 70 bars), supporting electrolyte, alkalinity and pH. Calculations suggest that enough alkalinity could be produced by reaction with plagioclase to reach saturation with respect to carbonate minerals; higher fCO (sub 2) conditions led to saturation with respect to dawsonite [NaAlCO (sub 3) (OH) (sub 2) ] at pH 3.6, and lower fCO (sub 2) conditions led to saturation with respect to calcite at pH 5.9 and at pH 6.9 (with and without 0.01 m starting alkalinity, respectively). The reacted plagioclase grains were analyzed by petrography, XRD, SEM/EDS, CO (sub 2) analysis, and AFM. Petrography and powder XRD did not reveal any carbonate precipitate. SEM and AFM images showed no evidence for secondary carbonate mineral precipitation, and analysis of the grains for CO (sub 2) exsolution after acidification revealed no carbonate source. The plagioclase dissolution rates were highest initially then progressively slowed as the solutions became more saturated with respect to the feldspar. Because of the complex initial aqueous conditions, dissolution congruency could not be precisely established. This work highlights the need for longer-term field and laboratory experiments to test geochemical aspects of CO (sub 2) sequestration, as well as for evolution of codes to better account for dissolution/growth inhibition, nucleation, and other processes.

AN - 51692715; 2005-052809 AB - Although CO (sub 2) reservoirs are commonly referenced as natural analogs to engineered geologic storage sites, there are important distinctions between these settings that may preclude their direct correlation. Most importantly, natural CO (sub 2) accumulations were established over geologic time frames, while CO (sub 2) injection at potential sequestration sites represents a dramatically telescoped and therefore very different thermal, hydrological, geochemical, and geomechanical perturbation of the reservoir/cap rock system. This distinction raises two intriguing possibilities that warrant quantitative investigation. First, the currently secure cap rock of a given natural CO (sub 2) accumulation may have evolved into such as a function of geochemical alteration that attended some degree of initial CO (sub 2) migration through it. Second, whether or not such evolution took place, this same cap rock may be incapable of providing an effective hydrodynamic seal in the context of an engineered injection. There are two corresponding fundamental questions. First, what is the evolution of cap-rock integrity during formation of natural CO (sub 2) reservoirs? Second, will such evolution be similar or appreciably different in engineered storage sites; i.e., what is its dependence on the rate, focality, and duration of CO (sub 2) influx? These questions--upon which strict validity of the natural-analog concept hinges--can be addressed using the reactive transport modeling approach. In this study, we will conduct and compare reactive transport simulations of a well-characterized CO (sub 2) reservoir under both natural and hypothetical anthropogenic "filling" modes. Our results will reveal the dependence of long-term cap-rock integrity on filling history, and thereby shed quantitative light on appropriateness of the natural-analog concept.

Absolute permeability is obtained from lattice-Boltzmann viscous flow simulation in the digital pore space, represented by zeros for the pores and ones for the mineral phase. The numerical results closely match measured permeability in the sample. We numerically alter the original digital sample by (a) depositing cement on the grain surface and (b) inserting small "silt" particles into the pore space. By calculating the permeability of the altered sandstone, we obtain permeability-porosity trends that differ depending on the diagenetic alteration process. We explore obtaining accurate permeability estimates from 2-D images. In this approach, the 3-D digital pore space realizations are generated from digitized 2-D images via statistical indicator simulation. We produce digital 2-D images from the original 3-D digital sample by slicing it in the computer. The 2-D porosity of the slices, on average, is the same as the measured 3-D porosity. However, the statistical spread around the average value is noticeable. It is remarkable that the calculated permeability of the statistically reconstructed 3-D realizations matches, on average, the calculated permeability of the original digital sample and also the measured permeability. Finally, we apply diagenetic alterations to 2-D slices, statistically reconstruct the corresponding 3-D samples, and calculate their permeability. The results indicate that in clastic sediments, absolute permeability can be accurately estimated from 2-D sections.

The results show that (super 10) Be concentrations in this area are mainly controlled by surface biological productivity, particle remineralization, and the degree of mixing with the Yangtze River and the Kuroshio waters. During the sampling periods (summer and autumn), the East China Sea was well stratified. Generally, the (super 10) Be water depth profiles can be divided into three layers: the surface mixed layer, the particulate (super 10) Be regeneration layer, and the bottom layer. Surface water (super 10) Be concentrations increase gradually towards the Kuroshio and increase sharply at the edge of the Kuroshio Current. Vertical distributions of (super 10) Be show that in the summer (super 10) Be is enriched in the bottom water near the Yangtze River estuary and the bottom water in the middle of the continental shelf. The two enriched areas are separated, probably by an intrusion of the Continental Coastal Water. In the autumn, (super 10) Be bottom enrichment only occurred in the western part of the East China Sea. This phenomenon is consistent with the seasonal circulation pattern change of currents induced by monsoon winds. The influence on (super 10) Be by the Kuroshio branch intrusion in the southern East China Sea northeast of Taiwan may be more significant than the Kuroshio main flow. Simple box model results indicate that (super 10) Be input from the Kuroshio Current is more important than Yangtze River input and atmospheric precipitation. About 81% of (super 10) Be input to the East China Sea is scavenged into the sediments and 19% of (super 10) Be flows out of the East China Sea by currents and water exchange. The (super 10) Be sedimentation flux in the East China Sea is nearly five times of the average global (super 10) Be production rate, suggesting that the East China Sea is an important sink for (super 10) Be.

(super 26) Al and (super 10) Be data acquired from numerous transects across distal, medial and proximal landscape positions suggest that sediment supplied to the Chemehuevi Mountain piedmont is mainly from the mountain source basins (4 X 10 (super 4) kg km (super -2) y (super -1) ) and the proximal bedrock pediment (3.3 X 10 (super 4) kg km (super -2) y (super -1) ). Relatively little of the sediment currently at the ground surface across the piedmont appears to be derived from erosion of incised alluvium and from the channel bed (0.2 X 10 (super 4) kg km (super -2) y (super -1) and 0.3 X 10 (super 4) kg km (super -2) y (super -1) , respectively). Nuclide activities of sediment collected from active channels increase steadily down the 12 km - long piedmont. Based on the sediment budget, the down piedmont increase in nuclide activity, and the thickness of sediment in active transport ( approximately 32 cm to approximately 17 cm from the rangefront to the distal piedmont, respectively) we modeled average sediment speeds of 8 to 39 cm y (super -1) . Nuclide analyses and soil development of two soil pits, located approximately 6 km and approximately 12 km from the rangefront, suggest complex histories of sediment deposition, surface erosion, and surface stability. Nuclide analyses of sediment from the pit 12 km from the rangefront suggests sediment deposition rates of 20 to 37 mm ky (super -1) until approximately 8,000 years ago when deposition was replaced by sediment transport. This interpretation is consistent with the observed soil characteristics that indicate that late Holocene sediments overlie early Holocene sediments at this pit. Soil development and nuclide analyses of sediment from the pit approximately 6 km from the rangefront suggests a complex history of sediment deposition (18 mm ky (super -1) ), surface erosion (truncated soil horizons), and surface stability (buried soils, as well as varnished pavement at the current ground surface) over the past approximately 70,000 years. By using cosmogenic nuclides we provide a new window into understanding the behavior of these enigmatic features over large spatial- and long temporal-scales.

Alluvial fans, pediment surfaces, shorelines and a thick succession of sediments within the basin coupled with moraines and associated landforms in the adjacent high mountains record a complex history of Late Quaternary paleoenvironmental change and landscape evolution. The Qaidam basin, one of the largest hyper-arid intermontane basins on Earth, is a natural laboratory to examine the nature of intermontane basin evolution within a continent-continent collision zone. Furthermore, it provides an opportunity to relate the timing of landscape evolution in a hyper-arid environment to climatic change and associated glacial and hydrological changes. Critical sites along the southern and northwestern margins of the Qaidam Basin provide evidence of a strong link between times of climatic amelioration, deglaciation, lake desiccation and alluvial fan sedimentation. From these observations we believe that the major landscape changes took place very rapidly over short intervals of time during periods of climatic instability. To test this hypothesis, we have undertaken remote sensing, field mapping, geomorphological and sedimentological analysis, and numerical dating of Late Quaternary landforms within the Qiadam basin. In particular, we have undertaken an extensive program of cosmogenic radionuclide (CRN) surface exposure dating to define the ages of Late Quaternary landforms. This is allowing us to test our hypothesis that the timing of formation of landforms is synchronous with times of climatic instability.

It is therefore essential to have a standard radiocarbon calibration datasets for such intercomparisons to be valid, rather than using an ad hoc mixture of (super 14) C datasets without proper consideration of potential errors in timescale or carbon reservoir corrections. The IntCal04 Radiocarbon calibration/Comparison Working Group has put together a set of criteria for assuring datasets are sufficiently robust in both the cal ages and the radiocarbon ages and that the uncertainties are quantified (Reimer et al., 2002). Refinements and additions to IntCal98 should result in a calibration dataset back to ca. 30 ka BP, which will be presented for ratification at the 19th International Radiocarbon Conference in Wellington, New Zealand. In addition, the IntCal04 Group is working towards a recommendation for comparing (super 14) C based chronologies beyond 30 ka BP where few absolutely dated records exist and there is wide discrepancy among them. We will highlight the differences between IntCal98 and the proposed IntCal04 dataset with example radiocarbon calibrations for some important climatic events.

Radiocarbon ages spanning the last 11,900 years are calibrated to calendar years by making radiocarbon age determinations on tree rings of a known age. Over this time interval, fluctuations in the atmospheric 14C were largely produced by changes in the solar magnetic field. For the age interval between 12,000 years and 50,000 yrs BP, radiocarbon ages are calibrated by less accurate methods, such as varved sediments, rapidly accumulating marine sediments, 230Th/234U/238U dating of spelothems, and 230Th/234U/238U dating of corals. In addition to solar contributions prevalent in the Holocene, carbon cycle variations contribute to atmospheric 14C fluctuations in the pre-Holocene. Combining published radiocarbon calibration data greater than 12,000 yrs. BP results in an unusable calibration data set because offsets and contradictions are the norm among these various data sets. Our contributions to the international radiocarbon calibration effort are the high precision 230Th/234U/238U and 14C analyses of a suite of unusually high quality coral samples cored from drowned reefs offshore several islands in the tropical Atlantic and Pacific oceans. We have overlapped and extended the tree-ring radiocarbon calibration from 11,000 to 50,000 yrs. BP in enough detail to be used as a stand-alone radiocarbon calibration of the highest quality. We have measured a radiocarbon anomaly produced during the Laschamp geomagnetic excursion that confirms the K/Ar date on the Laschamp flow at 47.4 + or - 1.9 kyrs BP reported by Hall and York (1978). This age is between 15% and 24% older than recent Laschamp age estimates based on ice core and marine core chronologies. The age offset between uncalibrated radiocarbon years and 230Th/234U/238U calendar years exceeds 9200 years during the Laschamp excursion. The radioactive decay of the Laschamp 14C anomaly, compounded by several smaller anomalies, results in the long-term convergence of radiocarbon and calendar years. Conveniently, the large 14C production anomaly produced during the Laschamp excursion "spiked" the carbon reservoirs with sufficient radiocarbon to effectively extend the useful range of radiocarbon dating to eight half-lives.

Glaciation in this region is controlled by two major climatic systems: the mid-latitude westerlies and the South Asian monsoon. In addition, significant interannual climatic variability in the region is associated with El Nino-Southern Oscillation. Furthermore, glaciation is strongly influenced by topographic constraints. Yet despite the regional and global importance of glaciation in High Asia, the dynamics, extent and timing of glaciation in this region are poorly understood and defined. To test the relative importance of the different climatic systems and topographic constraints on glaciation, as well as the associated hydrological changes, we have been systematically examining the glacial and associated geology throughout the region, and dating landforms and sediments using cosmogenic radionuclide (CRN) surface exposure and optically stimulated luminescence (OSL) techniques. To date, we have undertaken detailed studies in the following mountain regions: Chitral, Swat, Nanga Parbat, Hunza Valley, Lahul, Ladakh, Zanskar, Garhwal, Nanda Devi, Langtang, Khumbu, Gonga Shan, Gangdise, Nyainqentangulha, Tangula, Kunlun, Nianbaoyeze, Anyemaqen, La Ji and Qilian Shan. This work has included detailed mapping, together with nearly equal 1000 numerical dates on moraines and associated landforms that define the extent and timing of glaciation. These data indicate a strong monsoonal influence on glaciation, synchroneity of glaciation and topographic constraints on extent of glaciation throughout Tibet and the bordering mountains. Glacial oscillations are shown to correlate with changes in the hydrological system and sediment flux that, in turn, largely control landscape changes.

New evidence presented in this study is consistent with Holocene ages for these groundwaters. Isotopic, chemical, and hydrogeologic data suggest the Death Valley groundwaters are transported southward up to 300 km through regional carbonate aquifers of the Railroad Valley flow system. Groundwaters in the northern part of the flow system have delta (super 18) O values nearly identical to recharge derived from winter precipitation in central Nevada. Isotopic analyses of snow cores revealed kinetic isotope enrichments in the snowpack prior to melting may account for observed isotopic enrichments in groundwaters relative to the global meteoric water line. Geographically consistent trends in delta (super 18) O values, water chemistry, and carbon isotopes are observed along the entire 300 km regional flow path. Dissolved inorganic carbon quickly reacts with the carbonate aquifer due to elevated subsurface temperatures and cation exchange processes, yielding (super 14) C values <10 pmc within 30 km of the northernmost recharge area. Groundwater mixing along the flow path maintains uniformly low nonzero (super 14) C values. The complexities of the flow system preclude the application of (super 14) C age correction models. Hydrologic mass balance calculations imply turnover rates are too high to store significant amounts of pluvial recharge in the regional carbonate aquifer. Closed alluvial basins provide more favorable geologic environments for remnant accumulations of Pleistocene groundwater, as indicated by rare, isolated pockets of unusually low delta (super 18) O groundwater.

We describe an algorithm for simulating radiation diffusion on such a mesh, coupled to multi- fluid gasdynamics. Conservation laws are enforced by using locally conservative difference schemes along with explicit synchronization operations between different levels of refinement. In unsteady calculations each refinement level is advanced at its own optimal timestep. Particular attention is given to the appropriate coupling between the fluid energy and the radiation field, the behavior of the discretization at sharp interfaces, and the form of synchronization between levels required for energy conservation in the diffusion process. Two- and three-dimensional examples are presented, including parallel calculations performed on an IBM SP-2.

In the present study, we have made a matched repair-competent cell line by mutagenizing 5P3NAT2 cells with ethyl methanesulfonate and selecting for resistance to cytotoxicity by 2-amino-3-methylimidazo[4,5-f]quinoline (IQ). In the differential cytotoxicity (DC) assay, 4 out of 15 clones showed no cytotoxic effect with IQ at the highest dose (30 mu g/ml) tested, in contrast to repair-deficient 5P3NAT2 cells, which showed similar to 100% cytotoxicity at 0.3 mu g/ml. Subsequently, these IQ-resistant clones were examined for resistance to killing by UV irradiation. All four IQ-resistant clones, which show resistance to UV similar to that of repair-proficient AA8 cells, still express both the CYP1A2 and N-acetyltransferase genes. Sequence analysis of CXPD cDNA from the 5P3NAT2R9 clone revealed an A:T arrow right G:C reversion event at the site of the UV5 mutation. This base change results in reversion of the codon 116 tyrosine in UV5 cells back to the original cysteine in AA8 cells, thereby restoring wild-type CXPD activity and repair function. In contrast to 5P3NAT2 cells, the repair-proficient 5P3NAT2R9 revertant cell line shows little IQ-induced cell killing, and dramatically lower levels of induced mutation at the adenine phosphoribosyltransferase (Aprt) gene locus over the range of 2-40 mu g/ml IQ. This matched pair of repair-proficient/deficient cell lines can provide insight not only into the genotoxicity of heterocyclic amine dietary carcinogens such as IQ and PhIP, but also into the effects of nucleotide excision repair on the ultimate mutagenicity of these compounds.

Recently, the US Department of Energy approved the declassification of the NTS radionuclide inventory by principal geographic test centers. This permits unclassified publication of radionuclide totals for the Yucca Flat, Pahute Mesa- -Area 19, Pahute Mesa--Area 20, Frenchman Flat, and Rainier Mesa/Shoshone Mountain testing locations. Activities are reported as of September 23, 1992, the date of the last underground nuclear test conducted at the NTS, and September 23, 2492, after 500 years of radioactive decay. The availability of these data affords an opportunity for the analysis of the radiologic source term within the boundaries of local hydrogeologic units and provides insight to where radionuclides are sited relative to potential exposure pathways.

As the success of this emerging form of radiation therapy grows, accurate treatment planning and radiation dose simulations are likely to become increasingly important. To address this need, we have initiated the development of a new, Monte Carlo transport-based treatment planning system for molecular targeted radiation therapy as part of the MINERVA system. The goal of the MINERVA dose calculation system is to provide 3-D Monte Carlo simulation-based dosimetry for radiation therapy, focusing on experimental and emerging applications. For molecular targeted radionuclide therapy applications, MINERVA calculates patient-specific radiation dose estimates using computed tomography to describe the patient anatomy, combined with a user-defined 3-D radiation source. This paper describes the validation of the 3-D Monte Carlo transport methods to be used in MINERVA for molecular targeted radionuclide dosimetry. It reports comparisons of MINERVA dose simulations with published absorbed fraction data for distributed, monoenergetic photon and electron sources, and for radioisotope photon emission. MINERVA simulations are generally within 2% of EGS4 results and 10% of MCNP results, but differ by up to 40% from the recommendations given in MIRD Pamphlets 3 and 8 for identical medium composition and density. For several representative source and target organs in the abdomen and thorax, specific absorbed fractions calculated with the MINERVA system are generally within 5% of those published in the revised MIRD Pamphlet 5 for 100 keV photons. However, results differ by up to 23% for the adrenal glands, the smallest of our target organs. Finally, we show examples of Monte Carlo simulations in a patient-like geometry for a source of uniform activity located in the kidney.

AN - 72804704; 12505291 AB - 2-Amino-1-methyl-6-phenylimidazo [4,5-b] pyridine (PhIP), a mutagen/carcinogen belonging to the class of heterocyclic amines (HCAs) found in cooked meats, is a mammary gland carcinogen in rats and has been implicated in the etiology of certain human cancers including breast cancer. To gain insight into the genomic alterations associated with PhIP-induced mammary gland carcinogenesis, we used comparative genomic hybridization (CGH) to examine chromosomal abnormalities in rat mammary carcinomas induced by PhIP, and for comparison, by DMBA (7, 12-dimethylbenz[a]anthracene), a potent experimental mammary carcinogen. There was a consistent and characteristic pattern of chromosome-region loss in PhIP-induced carcinomas that clearly distinguished them from carcinomas induced by DMBA.

An in vitro transposition reaction is used to introduce a well-characterized replicon and selectable marker into purified plasmids, which are then used to transform E. coli. The approach was demonstrated using a small 3.4-kb archaeal plasmid and a large 60-kb uncharacterized plasmid from a Gram-negative bacterium. Replicon function in E. coli was tested for each plasmid, and direct sequencing of the large plasmid revealed similarity to restriction-modification systems.

AN - 72866669; 12634135 AB - Full toxicologic profiles of chemical mixtures, including dose-response extrapolations to realistic exposures, is a prohibitive analytical problem, even for a restricted class of chemicals. We present an approach to probing in vivo interactions of pesticide mixtures at relevant low doses using a monitor compound to report the response of biochemical pathways shared by mixture components. We use accelerator mass spectrometry (AMS) to quantify [14C]-diisopropylfluorophosphate as a tracer at attomole levels with 1-5% precision after coexposures to parathion (PTN), permethrin (PER), and pyridostigmine bromide separately and in conjunction. Pyridostigmine shows an overall protective effect against tracer binding in plasma, red blood cells, muscle, and brain that is not explained as competitive protein binding. PTN and PER induce a significant 25-30% increase in the amount of tracer reaching the brain with or without pyridostigmine. The sensitivity of AMS for isotope-labeled tracer compounds can be used to probe the physiologic responses of specific biochemical pathways to multiple compound exposures.

The contents of light noble gases (He, Ne, and Ar) and long-lived radionuclides ( (super 10) Be, (super 26) Al, (super 36) Cl, and (super 53) Mn), produced by nuclear reactions with cosmic rays, were measured in the separated metal and olivine phases from numerous samples representing a wide range of shielding conditions in the meteoroid. The distribution of cosmogenic nuclide concentrations in the metal follows patterns similar to that observed in large iron meteorites. Shielding effects were estimated from the relative proportions of low-and high-energy reaction products. The production rates varied, from surface to interior, by a factor of more than several hundred. The (super 36) Cl- (super 36) Ar cosmic-ray exposure age of Brenham is 156+ or -8 Myr. This determination is based on a multiple nuclide approach that utilizes cosmogenic nuclide pairs. This approach not only yields a "shielding independent" exposure age but also demonstrates that the production of cosmogenic nuclides occurred in a single stage. The depth profiles of (super 10) Be in the stone phase and (super 53) Mn in the metal phase are shown superimposed on corresponding profiles from the Apollo 15 long drill core. Surprisingly low abundances of lithophile elements, such as K, U, and Th, provided a unique opportunity to examine the production systematics of those nuclides whose inventories typically have significant contributions from non-cosmogenic sources, particularly radiogenic contributions. The U and Th contents of the olivine samples are extremely low, allowing detection of cosmogenic (super 4) He production from oxygen, magnesium, silicon, and iron.

The scatter in earthquake population discriminant measurements for fixed propagation paths is statistically analyzed to assess the spatial and frequency-dependent contributions from source radiation pattern and source depth variations along with variable near-source scattering. This is useful because procedures for reducing the variance caused by propagation effects must be constrained by knowledge of the intrinsic scatter resulting from independent source effects, for which corrections are not available without a priori knowledge of the source type and depth. Broadband waveforms for earthquakes near the Nevada Test Site (NTS) and in southern California recorded at stations of the Livermore NTS Network (LNN), the Caltech TERRA scope Network, and the Berkeley Digital Seismic Network (BDSN) are used to obtain Pg/Lg and Pn/Lg measurements and to assess source depth and mechanism contributions to measurement variance. Pn/Lg and Pg/Lg spectral amplitude ratios for several frequency bands between 0.5 and 10 Hz from vertical velocity waveforms are computed for a total of 18 tightly located clusters of earthquakes. For each cluster, we examine the correlations between observed Pn/Lg and Pg/Lg ratios and estimated source depths or predictions based on previously determined source mechanisms. Focal mechanism predictions do not match the observations well, likely due to strong near-source scattering and directivity effects that overwhelm the point-source radiation pattern. However, the data do show significant scatter even for sources only a few kilometers apart. Source depth produces some coherent trends, which can be emphasized by averaging results from multiple stations. These trends vary from region to region, presumably due to specific local crustal layering, but most of the variance is not deterministically predictable and appears to arise from strong variations in near-source scattering. Variance estimates for logarithmic amplitude ratios normalized by mean amplitude ratios vary from 0.01 to 0.05 for different phase pairs. Frequency-dependent variations of the mean, variance, minimum, and maximum amplitude ratio parameters show strong distance dependence out to about 300 km and then appear to become independent of event-station distance. These variance parameters appear to be suitable for use in spatial interpolations of observed P/S-type ratios for a specific unidentified event path, as needed for nuclear test monitoring.

Sea ice is the first variable to change during the last deglaciation, followed by nutrient proxies and sea surface temperature. The comparison of the marine records to Antarctic ice CO (sub 2) variation depends on the age model as (super 14) C determinations cannot be obtained for the time interval of 29.5-14.5 ka. Our diatom-based sea ice record is in phase with the sodium record of the Vostok ice core. If gas exchange played a major role in determining glacial to interglacial CO (sub 2) variations, the main cause of atmospheric pCO2 change must be sought elsewhere, rather than in the Southern Ocean.

We combined information on the molecular bonding of metals in solids from X-ray absorption spectroscopy (XAS) with thermodynamic and kinetic driving forces obtained from dissolved metal concentrations to deduce the dominant reactions under reduced and oxidized conditions. We evaluated the in situ geochemistry of metals (cadmium, chromium, iron, lead, manganese and zinc) as a function of sediment depth (to 100 cm) from a 60 year record of contamination at the Alameda Naval Air Station, California. Results from XAS and thermodynamic modeling of porewaters show that cadmium and most of the zinc form stable sulfide phases, and that lead and chromium are associated with stable carbonate, phosphate, phyllosilicate, or oxide minerals. Therefore, there is minimal risk associated with the release of these trace metals from the deeper sediments contaminated prior to the Clean Water Act (1975) as long as reducing conditions are maintained. Increased concentrations of dissolved metals with depth were indicative of the formation of metal HS super(-) complexes. The sediments also contain zinc, chromium, and manganese associated with detrital iron-rich phyllosilicates and/or oxides. These phases are recalcitrant at near-neutral pH and do not undergo reductive dissolution within the 60 year depositional history of sediments at this site. The fate of these metals during dredging was evaluated by comparing in situ geochemistry with that of sediments oxidized by seawater in laboratory experiments. Cadmium and zinc pose the greatest hazard from dredging because their sulfides were highly reactive in seawater. However, their dissolved concentrations under oxic conditions were limited eventually by sorption to or co-precipitation with an iron (oxy)hydroxide. About 50% of the reacted CdS and 80% of the reacted ZnS were bonded to an oxide-substrate at the end of the 90-day oxidation experiment. Lead and chromium pose a minimal hazard from dredging because they are bonded to relatively insoluble carbonate, phosphate, phyllosilicate, or oxide minerals that are stable in seawater. These results point out the specific chemical behavior of individual metals in estuarine sediments, and the need for direct confirmation of metal speciation in order to constrain predictive models that realistically assess the fate of metals in urban harbors and coastal sediments.

Polydimethylsiloxane (PDMS) is cast into an acrylic mold frame with suspended elements that are removed after curing to form chip cavities, inlet and outlet ports, microchannels, and reservoirs. The packaging approach enables the integration of off-the-shelf components such as pumps and valves with glass microfluidic devices, electronic chips, sample reservoirs, and flow channels. A particle pre-concentration module with a glass capture chip and integrated micropump is shown as an example. A pneumatically driven microfluidic pumping module is also shown. Custom microfluidic interconnects for interfacing to micro-scale fluidic systems are presented. The connectors are capable of withstanding more than 1000 psi and allow microdevices to be rapidly connected to macroscopic devices and systems, without the use of tools.

However, given the space limitations and the negative public perception of large volumes of waste, there is a growing international motivation to develop a fusion waste management system that maximizes the amount of material that can be cleared or recycled. In this work, we present an updated assessment of the waste management options for the HYLIFE-II inertial fusion energy (IFE) power plant, using the concept of clearance index (CI) for radioactive waste disposal. With that purpose, we have performed a detailed neutronics analysis of the HYLIFE-II design, using the TART and ACAB computer codes for neutron transport and activation, respectively. Whereas the traditional version of ACAB only provided the user with the gamma contact dose rate for recycling assessments and WDR as an index for waste disposal considerations, here we have modified the code to calculate CIs using the current international atomic energy agency (IAEA) clearance limits for radiological waste disposal. The results from the analysis are used to perform an assessment of the waste management options for the HYLIFE-II IFE design.

AN - 72681684; 12427531 AB - We review the genes and proteins related to the homologous recombinational repair (HRR) pathway that are implicated in cancer through either genetic disorders that predispose to cancer through chromosome instability or the occurrence of somatic mutations that contribute to carcinogenesis. Ataxia telangiectasia (AT), Nijmegen breakage syndrome (NBS), and an ataxia-like disorder (ATLD), are chromosome instability disorders that are defective in the ataxia telangiectasia mutated (ATM), NBS, and Mre11 genes, respectively. These genes are critical in maintaining cellular resistance to ionizing radiation (IR), which kills largely by the production of double-strand breaks (DSBs). Bloom syndrome involves a defect in the BLM helicase, which seems to play a role in restarting DNA replication forks that are blocked at lesions, thereby promoting chromosome stability. The Werner syndrome gene (WRN) helicase, another member of the RecQ family like BLM, has very recently been found to help mediate homologous recombination. Fanconi anemia (FA) is a genetically complex chromosomal instability disorder involving seven or more genes, one of which is BRCA2. FA may be at least partially caused by the aberrant production of reactive oxidative species. The breast cancer-associated BRCA1 and BRCA2 proteins are strongly implicated in HRR; BRCA2 associates with Rad51 and appears to regulate its activity. We discuss in detail the phenotypes of the various mutant cell lines and the signaling pathways mediated by the ATM kinase. ATM's phosphorylation targets can be grouped into oxidative stress-mediated transcriptional changes, cell cycle checkpoints, and recombinational repair. We present the DNA damage response pathways by using the DSB as the prototype lesion, whose incorrect repair can initiate and augment karyotypic abnormalities.

Another 10 age determinations from the younger Buzzards Bay moraine near Woods Hole, MA, indicate that this moraine complex was formed 18,800+ or -400 yr ago. These ages correlate approximately with the terminations of cooling cycles recorded in Greenland ice cores and coeval ice-rafting events, suggesting that the marginal position of this sector of the ice sheet was tightly coupled to North Atlantic climate during the last glacial maximum.

In this paper, we address the impact of these climate stabilization schemes on terrestrial biosphere using equilibrium simulations from a coupled atmosphere-terrestrial biosphere model. Climate stabilization would tend to limit changes in vegetation distribution brought on by climate change, but would not prevent CO sub(2)-induced changes in Net Primary Productivity (NPP) or biomass; indeed, if CO sub(2) fertilization is significant, then a climate-stabilized world could have higher NPP than our current world. Nevertheless, there are many reasons why geoengineering is not a preferred option for climate stabilization.

This study examined the application of time-domain reflectometry (TDR) to measure solute transport in hillslopes. Three different plot designs were used to examine the transport of a conservative tracer in the first 50 cm of a moderately sloping soil. In the first plot, which was designed to examine spatial variability in vertical transport in a 1 times 2 m super(2) plot, a single probe per meter was found to adequately characterize vertical solute travel times. In addition, a dye and excavation study in this plot revealed lateral preferential flow in small macropores and a transport pattern where solute is focused vertically into preferential flow pathways. The bypass flow delivers solute deeper in the soil, where lateral flow occurs. The second plot, designed to capture both vertical and lateral flow, provided additional evidence confirming the flow patterns identified in the excavation of the first plot. The third plot was designed to examine lateral flow and once again preferential flow of the tracer was observed. In one instance rapid solute transport in this plot was estimated to occur in as little as 3% of the available pore space. Finally, it was demonstrated that the soil anisotropy, although partially responsible for lateral subsurface transport, may also homogenize the transport response across the hillslope by decreasing vertical solute spreading.

AN - 85360015; pmid-12398458 AB - Analysis of array data from acoustic scattering in a random medium with a small number of isolated targets is performed in order to image and, thereby, localize the spatial position of each target. Because the host medium has random fluctuations in wave speed, the background medium is itself a source of scattered energy. It is assumed, however, that the targets are sufficiently larger and/or more reflective than the background fluctuations so that a clear distinction can be made between targets and background scatterers. In numerical simulations nonreflective boundary conditions are used so as to isolate the effects of the host randomness from those of the spatial boundaries, which can then be treated in a separate analysis. It is shown that the key to successful imaging is finding statistically stable functionals of the data whose extreme values provide estimates of scatterer locations. The best ones are related to the eigenfunctions and eigenvalues of the array response matrix, just as one might expect from prior work on array data processing in complex scattering media having homogeneous backgrounds. The specific imaging functionals studied include matched-field processing and linear subspace methods, such as MUSIC (MUtiple SIgnal Classification). But statistical stability is not characteristic of the frequency domain, which is often the province of these methods. By transforming back into the time domain after first diagonalizing the array data in the frequency domain, one can take advantage of both the time-domain stability and the frequency-domain orthogonality of the relevant eigenfunctions.

AN - 72194335; 12387617 AB - A combination of computational methods, electrospray ionization mass spectroscopy (ESI-MS), and NMR spectroscopy has been used to identify novel small molecules that bind to two adjacent sites on the surface of the C fragment of tetanus toxin (TetC). One of these sites, Site-1, binds gangliosides present on the surface of motor neurons, while Site-2 is a highly conserved deep cleft in the structures of the tetanus (TeNT) and botulinum (BoNT) neurotoxins. ESI-MS was used to experimentally determine which of the top 11 computationally predicted Site-2 candidates bind to TetC. Each of the six molecules that tested positive was further screened, individually and as mixtures, for binding to TetC in aqueous solutions by NMR. A trNOESY competition assay was developed that used doxorubicin as a marker for Site-1 to provide insight into whether the predicted Site-2 ligands bound to a different site. Of the six predicted Site-2 ligands tested, only four were observed to bind. Naphthofluorescein-di-beta-galactopyranoside was insoluble under conditions compatible with TetC. Sarcosine-Arg-Gly-Asp-Ser-Pro did not appear to bind, but its binding affinity may have been outside the range detectable by the trNOESY experiment. Of the remaining four, three [3-(N-maleimidopropionyl)biocytin, lavendustin A, and Try-Glu-Try] bind in the same site, presumably the predicted Site-2. The fourth ligand, Ser-Gln-Asn-Tyr-Pro-Ile-Val, binds in a third site that differs from Site-1 or predicted Site-2. The results provide a rational, cost- and time-effective strategy for the selection of an optimal set of Site-1 binders and predicted Site-2 binders for use in synthesizing novel bidendate antidotes or detection reagents for clostridial neurotoxins, such as TeNT and BoNT.

AN - 72105479; 12236810 AB - Three somatic mutation assays were evaluated in men exposed to low-dose, whole-body, ionizing radiation. Blood samples were obtained between 1992 and 1999 from 625 Russian Chernobyl cleanup workers and 182 Russian controls. The assays were chromosome translocations in lymphocytes detected by FISH, hypoxanthine phosphoribosyltransferase (HPRT) mutant frequency in lymphocytes by cloning, and flow cytometic assay for glycophorin A (GPA) variant frequency of both deletion (N/Ø) and recombination (N/N) events detected in erythrocytes. Over 30 exposure and lifestyle covariates were available from questionnaires. Among the covariates evaluated, some increased (e.g. age, smoking) and others decreased (e.g. date of sample) biomarker responses at a magnitude comparable to Chernobyl exposure. When adjusted for covariates, exposure at Chernobyl was a statistically significant factor for translocation frequency (increase of 30%, 95% CI of 10%-53%, P = 0.002) and HPRT mutant frequency (increase of 41%, 95% CI of 19%-66%, P < 0.001), but not for either GPA assay. The estimated average dose for the cleanup workers based on the average increase in translocations was 9.5 cGy. Translocation analysis is the preferred biomarker for low-dose radiation dosimetry given its sensitivity, relatively few covariates, and dose-response data. Based on this estimated dose, the risk of exposure-related cancer is expected to be low.

This kind of resolution provides a novel opportunity to follow the dynamic flow behavior on the pore scale and to verify new theoretical and numerical modeling approaches.

We illustrate how stratigraphic ordering, sedimentological, and historical data can be used quantitatively in the process of estimating earthquake ages. Calibrated radiocarbon age distributions are used directly from layer dating through recurrence intervals and recurrence probability estimation. The method does not eliminate subjective judgements in event dating, but it does provide a means of systematically and objectively approaching the dating process. Date distributions for the most recent 14 events at Wrightwood are based on sample and contextual evidence in Fumal et al. (2002) and site context and slip history in Weldon et al. (2002). Pallett Creek event and dating descriptions are from published sources. For the five most recent events at Wrightwood, our results are consistent with previously published estimates, with generally comparable or narrower uncertainties. For Pallett Creek, our earthquake date estimates generally overlap with previous results but typically have broader uncertainties. Some event date estimates are very sensitive to details of data interpretation. The historical earthquake in 1857 ruptured the ground at both sites but is not constrained by radiocarbon data. Radiocarbon ages, a peat accumulation rates, and historical constraints at Pallett Creek for event X yield a date estimate in the earliest 1800s and preclude a date in the late 1600s. This event is almost certainly the historical 1812 earthquake, as previously concluded by Sieh et al. (1989). This earthquake also produced ground deformation at Wrightwood. All events at Pallett Creek, except for event T, about A.D. 1360, and possibly event I, about A.D. 960, have corresponding events at Wrightwood with some overlap in age ranges. Event T falls during a period of low sedimentation at Wrightwood when conditions were not favorable for recording earthquake evidence. Previously proposed correlations of Pallett Creek X with Wrightwood W3 in the 1690s and Pallett Creek event V with W5 around 1480 (Fumal et al., 1993) appear unlikely after our dating reevaluation. Apparent internal inconsistencies among event, layer, and dating relationships around events R and V identify them as candidates for further investigation at the site. Conditional probabilities of earthquake recurrence were estimated using Poisson, lognormal, and empirical models. The presence of 12 or 13 events at Wrightwood during the same interval that 10 events are reported at Pallett Creek is reflected in mean recurrence intervals of 105 and 135 years, respectively. Average Poisson model 30-year conditional probabilities are about 20% at Pallett Creek and 25% at Wrightwood. The lognormal model conditional probabilities are somewhat higher, about 25% for Pallett Creek and 34% for Wrightwood. Lognormal variance sigma (sub ln) estimates of 0.76 and 0.70, respectively, imply only weak time predictability. Conditional probabilities of 29% and 46%, respectively, were estimated for an empirical distribution derived from the data alone. Conditional probability uncertainties are dominated by the brevity of the event series; dating uncertainty contributes only secondarily. Wrightwood and Pallett Creek event chronologies both suggest variations in recurrence interval with time, hinting that some form of recurrence rate modulation may be at work, but formal testing shows that neither series is more ordered than might be produced by a Poisson process.

Calendar age estimates for these earthquakes are based on a chronological model that incorporates radiocarbon dates from 18 in situ burn layers and stratigraphic ordering constraints. These five earthquakes occurred in about A.D. 825 (770-890) (mean, 95% range), A.D. 982 (840-1150), A.D. 1231 (1170-1290), A.D. 1502 (1450-1555), and after a date in the range of A.D. 1520-1680. The most recent surface-rupturing earthquake at Thousand Palms is likely the same as the A.D. 1676+ or -35 event at Indio reported by Sieh and Williams (1990). Each of the past five earthquakes recorded on the San Andreas fault in the Coachella Valley strongly overlaps in time with an event at the Wrightwood paleoseismic site, about 120 km northwest of Thousand Palms Oasis. Correlation of events between these two sites suggests that at least the southernmost 200 km of the San Andreas fault zone may have ruptured in each earthquake. The average repeat time for surface-rupturing earthquakes on the San Andreas fault in the Coachella Valley is 215+ or -25 years, whereas the elapsed time since the most recent event is 326+ or -35 years. This suggests the southernmost San Andreas fault zone likely is very near failure. The Thousand Palms Oasis site is underlain by a series of six channels cut and filled since about A.D. 800 that cross the fault at high angles. A channel margin about 900 years old is offset right laterally 2.0+ or -0.5 m, indicating a slip rate of 4+ or -2 mm/yr. This slip rate is low relative to geodetic and other geologic slip rate estimates (26+ or -2 mm/yr and about 23-35 mm/yr, respectively) on the southernmost San Andreas fault zone, possibly because (1) the site is located in a small step-over in the fault trace and so the rate is not be representative of the Mission Creek fault, (2) slip is partitioned northward from the San Andreas fault and into the eastern California shear zone, and/or (3) slip is partitioned onto the Banning strand of the San Andreas fault zone.

In a network of 38 trenches and creek-bank exposures, we have exposed a composite section of interbedded debris flow deposits and thin peat layers more than 24 m thick; fluvial deposits occur along the northern margin of the site. The site is a 150-m-wide zone of deformation bounded on the surface by a main fault zone along the northwest margin and a secondary fault zone to the southwest. Evidence for most of the 14 earthquakes occurs along structures within both zones. We identify paleoearthquake horizons using in filled fissures, scarps, multiple rupture terminations, and widespread folding and tilting of beds. Ages of stratigraphic units and earthquakes are constrained by historic data and 72 (super 14) C ages, mostly from samples of peat and some from plant fibers, wood, pine cones, and charcoal. Comparison of the long, well-resolved paleoseimic record at Wrightwood with records at other sites along the fault indicates that rupture lengths of past earthquakes were at least 100 km long. Paleoseismic records at sites in the Coachella Valley suggest that each of the past five large earthquakes recorded there ruptured the fault at least as far northwest as Wrightwood. Comparisons with event chronologies at Pallett Creek and sites to the northwest suggests that approximately the same part of the fault that ruptured in 1857 may also have failed in the early to mid-sixteenth century and several other times during the past 1200 years. Records at Pallett Creek and Pitman Canyon suggest that, in addition to the 14 earthquakes we document, one and possibly two other large earthquakes ruptured the part of the fault including Wrightwood since about A.D. 500. These observations and elapsed times that are significantly longer than mean recurrence intervals at Wrightwood and sites to the southeast suggest that at least the southernmost 200 km of the San Andreas fault is near failure.

We conducted a paleoseismic investigation to better understand the Hayward fault's past earthquake behavior. The site is near the south end of Tyson's Lagoon, a sag pond formed in a right step of the fault in Fremont. Because the Hayward fault creeps at the surface, we identified paleoseismic events using features that we judge to be unique to ground ruptures or the result of strong ground motion, such as the presence of fault-scarp colluvial deposits and liquefaction. We correlate the most recent event evidence (E1) to the historical 1868 M 6.9 earthquake that caused liquefaction in the pond and recognize three additional paleoruptures since A.D. 1470+ or -110 yr. Event ages were estimated by chronological modeling, which incorporated historical and stratigraphic information and radiocarbon and pollen data. Modeled, mean age and 95-percentile ranges of the three earlier events are A.D. 1730 (1650-1790) yr (E2), A.D. 1630 (1530-1740) yr (E3), and A.D. 1470 (1360-1580) (E4). The ages of these paleoearthquakes yield a mean recurrence of 130+ or -40 yr. Although the mean recurrence is well determined for the period A.D. 1470-1868, individual interval are less well determined: E1-E2, 140 +80/-70 yr; E2-E3, 100 +90/-100 yr; and E3-E4, 150 +130/-110 yr.

The PSHA results are being used both for developing the seismic design of preclosure facilities and for evaluating the postclosure performance of the repository. The PSHA inputs were provided by 6 teams of 3 experts each for seismic source and fault displacement characterization (SSC) and by 7 individual experts for ground motion (GM) characterization. Approximately 20 faults within approximately 20 km of the site and up to 36 regional faults (out to approximately 100 km) were included in the SSC experts' characterizations. The most significant local faults included the Bow Ridge, Paintbrush Canyon, Solitario Canyon, and Stagecoach Road faults, which bound major crustal blocks at Yucca Mountain. These faults are characterized by low slip rates of approximately 0.001-0.05 mm/yr and recurrence intervals of 10,000 to more than 100,000 years. The experts' maximum magnitudes (Mmax) ranged from M 5.7-6.8. The most significant regional faults were the Death Valley and Furnace Creek faults with slip rates of 2.5-8.0 mm/yr and Mmax of M 7.0-7.5. Areal source zones were also characterized to account for background seismicity not associated with known faults and faults not specifically characterized by the experts; their parameters were derived from the historical seismicity record. Mmax in the range of M 6.0-7.5 were assigned to these zones. These Mmax were reduced to M 5.0-6.6 in the site vicinity because of the detailed characterization of faulting The GM experts estimated ground motions and uncertainties for a matrix of magnitudes, source-to-site distances, and faulting styles based on empirical data and numerical ground motion modeling. Attenuation relationships were derived from regressing on these ground motions. Based on the experts' input, the probabilistic hazard for ground shaking was calculated. Several approaches to characterize fault displacement potential were also developed by the SSC experts based primarily on paleoseismic observations of faulting at the site. Based on the experts' input, the probabilistic hazard for fault displacement was calculated at several points near and within the repository footprint.

Widespread debris flows, triggered by extraordinarily heavy rains in 1995, were a dramatic reminder that these fans are active landforms. Debris flow events, particularly those large enough to transport the greater than car-size boulders we sampled, can be a significant geologic hazard to those living on the fans; thus, it is important to know the age and recurrence interval of boulder deposition. We measured 10-Be and 26-Al in samples collected from the top of 21 boulders on the General's Fan, a complex landform adjacent to Kinsey Run in western Madison County, VA. Model exposure ages (SL, >60 degrees , 10-Be PR = 5.17 atoms/g) for these samples range from about 7 to 140 ky. There is no relation between boulder size or boulder height and age; nor is there strong spatial patterning of boulder ages on the fan surface. We do not know the nuclide activity that the boulders contained when they were deposited; nor do we know how much they have eroded since deposition. Large inventories of meteoric 10-Be, measured in soil profiles underlying the boulders, suggest that the fan surfaces on which the boulders sit are old and stable, the oldest exceeding 500 ky. An exceedance probability plot of boulder ages shows a non-random distribution through the last 150 ka. Boulder ages cluster in times known to be cold (18, 30, 67, 105, and 140 ky), consistent with periglacial processes supplying more boulders at high elevation and/or more moisture effective conditions catalyzing increased debris flow activity and boulder transport.

Using cosmogenic dating ( (super 10) Be) of boulders on moraines in Alcacocha Valley (S 11 degrees 03', W 75 degrees 58', elev. approximately 4100-4800 m), we have identified deposits ranging in age from the last glaciation ( approximately 12-31 ka) to >1.0 Ma. Moraines of the last glacial maximum are farther upvalley and smaller than large outer moraines of older glaciations. Preservation of the older moraines and of polished surfaces on some old boulders argues for extremely low boulder erosion rates. We estimate a maximum erosion rate of approximately 0.3 m/Myr, which approaches published rates for Antarctica and suggests that aridity is important in slowing boulder erosion. Our findings are consistent with results from other Andean locations where moraines of the last glacial maximum are less extensive than those of older glaciations. The apparent decrease in glacial extent and ice volume in the Junin Plain during the Quaternary may have been controlled by tectonics, climate, or a combination of both. A late Tertiary pulse of tectonism may have resulted in an increase in high-elevation topography in the Junin region, allowing growth of large ice masses. The subsequent trend in decreasing ice volume could be a result of either a decrease in the area of high-elevation topography through glacial erosion or a decrease in the amplitude of climate variability. These hypotheses could be tested by analysis of the sediment record preserved in the Junin basin.

Was this incision driven by tectonic or climatic forcing? When did it occur? In order to infer the cause and understand the timing, spatial distribution, and rate of the bedrock incision in two such gorges, we collected >70 samples for 10-Be and 26-Al analysis from exposed, fluvially eroded outcrops of quartz-bearing schist along strath terraces of the Potomac and Susquehanna Rivers at the Piedmont/Coastal Plain transition. Here we report primarily on the Potomac gorge. The first 18 samples, collected from Mather Gorge below Great Falls on the Potomac River, indicate that the most prominent strath terrace, a several km-long bedrock feature 20 to 25 m above the current low water level, was abandoned rapidly as the Potomac River incised about 30 kya (SL, >60 degrees , 10-Be PR = 5.17 atoms/g). Nine samples, collected from water-polished rock surfaces down a cross-section from this terrace to just above the river, have decreasing nuclide activities consistent with a fluvial, bedrock incision rate of about 70 cm/ky and an effective 6 ky exposure age at water level. Four samples, collected from below the normal low-flow level during the 2000 drought, have activities equivalent to about 5 ky of exposure. Thus, to account for cosmic-ray dosing at and just below the water's surface, we have subtracted 6 ky of exposure from older terrace surface ages. The incision of Mather Gorge began about 30 ky coincident with a major drop (>50 m) in eustatic sea level, the result of glacial ice-volume increase. Incision is clearly coincident with cooling climate but we do not know if it was driven by base-level fall or by changes in discharge and sediment loading. However, the similarity of model exposure ages for samples collected from a km-long transect parallel to the river and within 2 km of the present-day knick point at Great Falls, suggests that retreat of the knick point which formed the gorge must have been rapid, lasting only a few thousand years.

AN - 51860277; 2004-033184 AB - If it becomes necessary to purposefully capture and sequester fossil-fuel-generated CO (sub 2) , a variety of ocean, land, and underground storage options are being considered. However, many of these approaches are expensive, have potentially serious environmental impacts, and/or may ultimately be ineffective in keeping CO (sub 2) from the atmosphere. As an alternative we propose that CO (sub 2) -rich power-plant gases be first hydrated with seawater to produce a carbonic acid solution that in turn is reacted on-site with limestone to form primaily Ca (super 2+) and HCO (sub 3) (super -) . This calcium bicarbonate solution is then released and diluted in the ocean where it would add minimally to the existing, large pool of these ions in the sea. Such a process simply speeds up natural, abiotic carbonate weathering and dissolution which will otherwise consume anthropogenic CO (sub 2) , but over many millennia. Using a model of ocean chemistry and transport we show that this process would increase ocean alkalinity, helping to neutralize CO (sub 2) acidity and isolating anthropogenic carbon from the atmosphere. Relative to atmospheric release or direct CO (sub 2) injection into the sea, this method would greatly expand the capacity of the ocean to store anthropogenic carbon while minimizing environmental impacts of this carbon storage on ocean biota. Our calculations indicate that releasing the carbonate-dissolution effluent to the oceans would be less damaging to the marine environment than releasing an equivalent amount of CO (sub 2) directly to the atmosphere. This sequestration method is also less energy intensive and less expensive than abiotic CO (sub 2) capture and direct ocean or geologic injection schemes. We calculate an energy penalty that may be $90/tonne CO (sub 2) and >>20% energy penalties estimated for direct, deep ocean or subterranean CO (sub 2) injection. Our initial benchtop-scale experimental simulation of this process indicates that carbonate dissolution could contribute significantly to mitigating adverse impacts of fossil-fuel burning.

These data provide new information on Holocene climatic changes in the mid-continent of North America. The SL chronology is based on 26 AMS (super 14) C dates of terrestrial plant macrofossils, and the LO chronology is established with 8 AMS (super 14) C dates of charcoal flakes. An abrupt transition to warm/dry climatic conditions of the middle Holocene occurred at 7.8 cal ka, as indicated by increases in delta (super 18) O (-9.8 per mil to -7.3 per mil, SL), quartz content (10% to 43%, SL), aragonite/calcite ratio (0.7 to 1.4, LO), and non-arboreal pollen abundance (34% to 56%, SL). This transition probably resulted from a major reorganization in global atmospheric circulation, but it appeared to postdate the 8.2 ka event. Within the middle Holocene, our isotopic, mineralogical, and biological data exhibit two distinct climatic periods with warmer/drier conditions between 7.8 and 5.8 cal ka than between 5.8 and 3.5 cal ka. Superimposed on this pattern are millennial-scale shifts in drought intensity and prairie vegetation, as evidenced by oscillations in aragonite/calcite ratio, % Poaceae pollen, charcoal abundance, and C (sub 4) -plant abundance. For example, the aragonite/calcite ratio of the LO sediments reaches peak values at 7.5 cal ka, 6.2 cal ka, and 5.0 cal ka, suggesting driest climatic conditions at these times, and minimal values at 6.8 cal ka and 5.5 cal ka, suggesting wetter phases of the middle Holocene. These oscillations have a approximately 1300-year pacing but do not appear to coincide with the ice-rafted-debris events in the North Atlantic.

Water from each of these sources have unique chemical and isotopic fingerprints as well as varying residence times within a watershed. Monitoring changes in stream water chemistry through time provides a basis for determining the influence of each water source on the chemical composition of streams. Sagehen basin is a high elevation watershed in the Sierra Nevada near Truckee, California. Recent studies in Sagehen Basin revealed a positive correlation between residence times of shallow groundwaters and their chemical compositions. This relationship between residence times chemical compositions provides a framework for interpreting chemical changes in Sagehen Creek. Chemical and isotope composition data collected weekly from Sagehen Creek suggests that the delta O-18 of Sagehen Creek during the snowmelt period responds rapidly to snowmelt pulses. The delta O-18 ratio of Sagehen Creek is more negative and similar to isotope ratios measured in the snowpack early in the snowmelt period during the peak discharge. The subsequent increase in the delta O-18 during the baseflow recession is concurrent with the decrease in discharge. Changes in major ion chemistry, including calcium, sodium, magnesium, silica, potassium, occur simultaneously, however, the response lags approximately two weeks behind changes in delta O-18. During late summer and fall, the chemical and isotope composition of Sagehen Creek reflect that of shallow groundwater with a residence time of approximately 20 years. The stoichiometery of solutes in Sagehen Creek is related to the primary weathering reactions occurring the glacial till, and is consistent throughout the year, suggesting that the composition of shallow groundwater and dilution by snowmelt are the primary controls on the solute chemistry and delta O-18 composition of Sagehen Creek. Additionally, Sagehen Creek is more concentrated, and thus being fed by groundwater with longer residence times during periods of baseflow than other similar Sierra Nevada streams, suggesting a substantial groundwater system is supporting this watershed.

EQ3/6 was used to model alteration scenarios with available kinetic data. Calculation predictions were tested in four experiments to determine if certain carbonate minerals would form under specific laboratory conditions. Each experiment used Dickson-type rocking gold bag autoclaves running for 3 to 5 months with 75-100 mu m-sized An (sub 60) plagioclase grains at 150 degrees C and pressures of 100 bars. Variables include initial CO (sub 2) fugacity (from 0.15 to 70 bars), supporting electrolyte, alkalinity and pH. Calculations suggest that enough alkalinity could be produced by reaction with plagioclase to reach saturation with respect to carbonate minerals; higher fCO (sub 2) conditions led to saturation with respect to dawsonite [NaAlCO (sub 3) (OH) (sub 2) ] at pH 3.6, and lower fCO (sub 2) conditions led to saturation with respect to calcite at pH 5.9 and at pH 6.9 (with and without 0.01 m starting alkalinity, respectively). The reacted plagioclase grains were analyzed by petrography, XRD, SEM/EDS, CO (sub 2) analysis, and AFM. Petrography and XRD did not reveal any carbonate precipitate. SEM and AFM images showed no evidence for secondary carbonate mineral precipitation, and analysis of the grains for CO (sub 2) exsolution after acidification revealed no carbonate source. The plagioclase dissolution rates were initially high but progressively slowed as the solutions became more saturated with respect to the feldspar. Because of the complex initial aqueous conditions, dissolution congruency could not be precisely established. This work highlights the need for longer-term field and laboratory experiments to test geochemical aspects of CO (sub 2) sequestration, as well as for evolution of codes to better account for dissolution/growth inhibition, nucleation, and other processes.

One approach is to sequester less-pure CO2 waste streams that are less expensive or require less energy to separate from flue gas, a coal gasification process, etc. The objective of this research is to evaluate the impacts of CO2 itself, as well as an impure CO2 waste stream, on geologic sequestration using reaction progress models, reactive transport simulators and analogous reactive transport experiments run in a plug flow reactor. We have investigated two generic reservoir rock scenarios: a feldspathic sandstone and a mixed calcite/dolomite carbonate. Models and experiments reacted these rocks with aqueous fluids that were initially equilibrated with respect to supercritical CO2 under anticipated disposal temperatures and pressures. The contaminant gases included H2S and SO2 and in our kinetic modeling we specifically accounted for acid catalysis of mineral dissolution reactions. Our modeling results with the sandstone reservoir rock suggested the possible formation of the mixed hydroxyl carbonate mineral dawsonite (NaAlCO3(OH)2). We are investigating this possibility by running closed system experiments in flexible gold bag reactors under conditions that should favor its formation. Our initial reactive transport experiments in the plug flow reactor will use sandstone from the Frio Fm (TX) and are designed to provide information useful in planning a CO2 geologic sequestration pilot field project.

In situ mollusks that are radiocarbon dead (>54,000 yr BP, Loken, 1966) led to the interpretation of the delta as an early Wisconsinan or pre-Wisconsinan ice-marginal feature. Hence, the delta became the cornerstone of the minimal model for Laurentide ice extent in the eastern Canadian Arctic during the Last Glacial Maximum (LGM). Large boulders resting on delta surfaces have been explained previously by 1) iceberg rafting, 2) surface reworking by sea-ice, or 3) mass wasting from glacier margins. We used cosmogenic nuclides to date four boulders lying on the surface of Cape Aston delta and one frost-rived block from a nearby bedrock knoll (125 m asl). Three of the four boulders exhibit LGM 10Be exposure ages (12.0+ or -0.5 ka, 17.6+ or -0.5 ka, 13.6+ or -0.4 ka; using 5.17 10Be PR), whereas the fourth boulder and the bedrock sample from the knoll have pre-LGM ages (96.2+ or -2.4 ka and 140.6+ or -3.5 ka, respectively). Because the highest dated LGM shoreline in the area lies at approximately 30 m asl, deposition of the boulders cannot be explained by 1) or 2) above. Mass wasting, 3) above, such as debris flows or slush avalanches, could explain deposition of some boulders, if the LGM ice margin were near the delta apex, but probably not the largest boulders, which are up to 10 m in diameter. Moreover, boulders are not found within sediments exposed by numerous deep meltwater channels that dissect the delta surface. We propose an alternative explanation, deposition of boulders by cold-based LGM ice. Thus, this foreland, and perhaps others along the NE Baffin Island coast, was glaciated by non-erosive cold-based ice during the LGM, leaving the underlying in situ shells and pre-LGM delta undisturbed. This scenario is compatible with recent exposure dating evidence for vigorous warm-based ice streams that occupied Baffin fiords during the LGM. Ongoing work involves analysis of dozens of additional samples collected from boulders on Cape Aston delta and from boulders and bedrock on the highest ground (up to 550 m) across the surrounding forelands to determine both lateral and vertical extent of LGM ice.

Successful implementation of this approach hinges on our ability to predict the relative effectiveness of subsurface CO (sub 2) migration and sequestration processes as a function of key reservoir and cap-rock properties, which will enable us to identify optimal target formations and evaluate their long-term isolation performance. Quantifying this functional relationship requires a modeling capability that explicitly couples multiphase flow and kinetically controlled geochemical processes. We have developed a unique computational package that meets these criteria by integrating a state-of-the-art reactive transport simulator (NUFT) and supporting geochemical software and databases (SUPCRT92 and GEMBOCHS). We have used this capability to model saline-aquifer disposal at Statoil's North-Sea Sleipner facility during both prograde (active-injection) and retrograde (post-injection) phases of the process. Simulation results suggest that in the near-field environment of Sleipner-like settings roughly 85% by mass of injected CO (sub 2) remains and migrates as an immiscible fluid phase (subject to hydrodynamic and structural trapping), about 15% dissolves into formation waters (solubility trapping), and <1% precipitates as carbonate minerals (mineral trapping). Although seemingly negligible, mineral trapping has enormous strategic significance. We have identified four distinct mechanisms: siderite-magnesite precipitates within inter-bedded and cap-rock shales, dawsonite cementation occurs throughout the intra-aquifer plume, and siderite-magnesite-calcite rind forms along both lateral and upper plume boundaries. Local porosity and permeability are reduced by each of these mechanisms; however, such reduction is most extreme in clay-rich shales, owing to their relatively large Fe and Mg concentrations. In our 20-year simulations, initial porosity and permeability of the basal cap-rock shale have been reduced by 8% and 22%, respectively. Hence, the strategic significance of mineral trapping: it continuously improves seal integrity and therefore containment of the voluminous immiscible plume and solubility-trapped CO (sub 2) .

We measured concentrations of cosmogenic nuclides in quartz extracted from stream sediment from 13 catchments to provide estimates of erosion rates at time scales from 10 (super 3) to 10 (super 5) yr. Preliminary analysis of 10Be activity from small (<50 km (super 2) ), upland catchments in Colorado and Wyoming indicates that the landscape is lowering at rates between 14 and 250 m/MY in this semiarid area. We sampled basins that: (1) have not been glaciated; (2) have only small volumes of sediment stored beneath terraces and in colluvium, and (3) display minimal evidence for anthropogenic disturbance. We measured the (super 10) Be content of the 250 to 710 mm sand fraction collected in cross-channel transects. Our initial data do not show strong influence of basin relief, average slope, drainage area, tectonic environment, or climate. However, the range of erosion rates from different lithologies suggests that relative rock resistance exerts strong control on landform evolution in the Rocky Mountain region. Catchments draining weathered Precambrian basement (granites and gneisses) typical of the northern Front, Laramie and Medicine Bow Ranges give erosion rates of 18 to 30 (24+ or -6; n = 9) m/MY. Weakly lithified Middle and Upper Cenozoic basin fill is eroding at rates of 45 to 250 m/MY at sites in southern Wyoming and northern Colorado. Precambrian quartzite exposed in the eastern Uinta Mountains gave a rate of 14 m/MY, the lowest we measured. Erosion rates measured in upland granitic and gneissic catchments in Colorado are comparable to those measured in other non-orogenic areas such as the southern Appalachians. If our initial measurements for erosion rates of weakly lithified basin fill are typical, most of the middle and late Cenozoic fill in the greater Wyoming area could have been stripped in the past 5 to 10 million years.

Dismukes et al. (2001) argued that bicarbonate preceded water as the preferred reductant for oxygenic photosynthesis, postulating a transition stage in the Archean when a bacterial photosynthetic precursor to cyanobacteria utilized bicarbonate, then with the drop of carbon dioxide level cyanobacteria emerged using water instead of bicarbonate. Thermodynamic calculations give a 5 to 10 fold drop in bicarbonate levels with the onset of a methane-dominated greenhouse assuming surface temperatures of about 60 degrees C and a drop in the level of atmospheric carbon dioxide from about 1 to <0.03 bars. Cyanobacterial emergence at 2.8 Gya coincides with the first evidence of atmospheric methane, the negative excursion in the organic carbon isotope record. We propose that the long-term buildup of atmospheric methane in the early Archean culminated with a methane-dominated greenhouse at about 2.8 Gya, with a concomitant reduction in atmospheric carbon dioxide levels. Surface temperatures were declining from about 80-85 to 60-70 degrees C from 3.8 to 2.8 Gya, with temperature the stronger driver of silicate weathering than atmospheric carbon dioxide level (Schwartzman, 1999). Far less methane is needed to maintain climatic temperatures than carbon dioxide. This scenario is also consistent with lower ambient temperatures for this transition. Thus, we propose the onset of the methane-dominated greenhouse triggered the emergence of cyanobacteria. The earlier emergence of phototrophy is consistent with its upper temperature limit of about 75 degrees C. The proposed drop in atmospheric carbon dioxide level had two consequences, the emergence of cyanobacterial oxygenic photosynthesis and its carbon dioxide-concentrating mechanism, an adaptation to declining carbon dioxide to oxygen ratios in the external environment since the Archean greenhouse transition.

The Dong Co conjugate fault system is centered along the E-trending Bangong-Nujiang suture zone. The conjugate fault system is comprised of the NE-striking left-slip Riganpei Co fault to the north and NW-striking right-slip Gyaring Co fault to the south. These structures accommodate a portion of Indo-Asian convergence and long term slip-rates determined along these faults indicate north-south contraction is occurring across Central Tibet at a rate of approximately 2 mm/yr. Preliminary interferograms were constructed using descending orbital tracks of the ERS 1 and ERS 2 European Space Agency satellites with a time-span of seven years. Surface displacement maps along the radar line of sight indicate a significant strain gradient from the NW to SE centered along the Riganpei Co fault, and is consistent with left-slip. Our preliminary InSAR results are consistent with geologic observations and suggest little variation in the near-field strain rate since about 7 ka.

These decisions typically require data interpretation by technical analysts who add their site-specific and professional knowledge to evaluate the significance of these data. For many large sites, simply handling the large database of ground water, chemical and geological data can prove a difficult and time-consuming task. Many sites have invested in geographic information systems (GIS) to address this problem. However, these applications still require input from technical analysts to integrate and interpret the wide range of data to produce results that are useful to decision makers. Therefore, computer algorithms are a cost-effective means to aid analysts in preparing the maps needed by managers to make timely project decisions. At Lawrence Livermore National Laboratory, the development of a consistent set of ground water elevation, plume, and geology maps that cover the entire project history was essential for implementing and managing the extensive remediation system. These maps were required for each hydrostratigraphic unit (HSU) defined in the site conceptual model. To accomplish this task, a rule-based computer algorithm was developed to create a consistent procedure that integrates multiple data sets both spatially and temporally based on a rigorous set of rules. The resulting maps were reviewed with respect to the site hydrogeological conceptual model to verify accuracy and consistency. Once the procedure was verified, the algorithm allowed for the rapid generation of thousands of dependable site maps covering the entire project history. The purpose of the algorithm is to support the technical analyst by allowing more time spent on data analysis rather than data compilation. By using this rule-based computer algorithm, LLNL has been able to maintain a strong data analysis support effort for decision-makers even as resources and staff have been re-directed to other aspects of the project. This work was performed under the auspices of the U.S. Department of Energy by the University of California, Lawrence Livermore National Laboratory under contract No. W 7405-Eng-48.

The DST is designed to investigate the coupled thermal - mechanical - hydrologic - chemical (TMHC) processes expected in a geological high-level nuclear waste repository. The heat source in the DST includes nine floor heaters in the 48-m long Heater Drift (HD), and 25 wing heaters that extend about 10 m outward from both sides of the HD. The parameters measured in the DST include heater power, temperature, moisture content, rock mass displacement, air permeability, thermal conductivity and thermal diffusivity, deformation in the concrete liner, and chemistry of gas and water samples. The heating phase of the DST was from December 3, 1997 to January 14, 2002. By October 2002 the DST will be in its ninth month of the planned 4-year natural cooling phase. The rock mass temperature in the DST is measured with resistance temperature devices (RTD) that are grouted in 28 holes. The measured temperatures provide good indications of the thermal-hydrologic processes during the test. The temperature-time history at each RTD shows that the dominant processes are heat conduction, and evaporation and boiling of pore water. Spatial variation of temperature shows the balancing of energy by thermal-hydrologic processes. The spatial distribution of the temperature-time curves shows that the boiling point of the pore water may vary with distance from the heat source, indicating the effect of the thermal-hydrologic-chemical process. The boiling point of the pore water may have been influenced by the variation of water chemistry caused by rock-water interactions.

Interestingly, extensive areas of the park were formerly occupied by military bases and only minimally developed. GGNRA is a wonderful field trip destination for adult education divisions of UC Berkeley and other Bay Area institutions because it highlights a wide variety of geologic subjects and processes. The adult education courses attract students from many different professions, although K-12 teachers primarily request credit for the classes. GGNRA includes rocks that formed at divergent, convergent, and transform plate boundaries and that record interactions of the North American, Pacific, and Farallon plates during the past 200 Ma. The Marin Headlands north of the Golden Gate Bridge include Mesozoic pillow basalts that formed on the Farallon plate at a divergent boundary, and the overlying radiolarian ribbon cherts record 100 Ma of starved sedimentation as the plate traveled across the Pacific Basin. The serpentine, sandstone/shale melange, and metamorphic blocks of the Franciscan complex near the south side of the Golden Gate Bridge record subduction processes and development of shear zones at a convergent plate boundary. The Franciscan subduction complex of the North American plate is separated from the granitic basement rocks of the Salinian terrane on the Pacific plate at Point Reyes National Seashore by the San Andreas transform fault. The Salinian terrane records significant lateral displacement from at least Southern California. The class discussions also focus on Quaternary climatic cycles and resulting sea level fluctuations as well as their influence on the evolution of San Francisco Bay and surrounding areas. Finally, the topic of man as an agent of geologic change in the Bay Area is related to historical events since the gold rush of 1849. Teaching adult education courses in GGNRA is extremely rewarding because of the students' genuine interest in geology and their desire to learn about the processes that shaped familiar landscapes through time and space.

A long-standing debate over the reconstruction of former ice sheets revolves around the use of relative weathering of landscapes, i.e., the assumption that highly-weathered landscapes have not been recently glaciated. New cosmogenic isotope measurements from northeastern Baffin Island shed light on this debate. Average (super 10) Be and (super 26) Al ages for two tors on a approximately 500 m upland adjacent to the mouth of Clyde Inlet, a 150-km-long fiord that penetrates interior Baffin Island, are >66.9+ or -5.1 ka and >62.1+ or -1.8 ka (SL, >60 Be PR = 5.1 atoms/g; Al PR = 31.1 atoms/g). The tors, on local summits approximately 100 m above the highest lateral moraines and other clear signs of actively-eroding ice, are deeply weathered, exhibiting large weathering pits, grus, and quartz veins and knobs that stand in relief. Three erratics perched directly on the ancient tors have average (super 10) Be and (super 26) Al ages of 16.7+ or -1.3 ka, 11.9+ or -0.6 ka, and 10.5+ or -0.8 ka. These results suggest that non-erosive ice overran highly-weathered upland surfaces along the northeastern margin of the LIS during the LGM. These data invalidate the use of relative weathering to define LIS margins in the eastern Canadian Arctic, and possibly elsewhere, especially where perched blocks have been described on weathered upland surfaces along the fringes of Northern Hemisphere Pleistocene ice sheets. The proximity of non-erosive plateau ice to erosive fiord ice requires strong gradients in basal thermal regimes, suggestive of an ice-stream mode of glaciation. We propose that this style of glaciation dominated the fiord coastline of northeastern Baffin Island where the topography and glacial geology is similar to the Clyde region. Ice-stream-dominated ice-sheet margins are dynamic and unstable, and consequently, the northeastern margin of the LIS was probably involved in abrupt climate changes, especially those including the coupling of ice sheets and oceans (e.g., Heinrich Events).

Vital to the operation of the canal is the large and consistent supply of water from the Rio Chagres basin mediated by Lake Alhajuela, the reservoir to the Panama Canal. In addition to water, the headwater basins supply sediment that reduces the storage potential of the reservoir. We chose the headwater basin of the Rio Chagres to investigate the background rates of sediment generation in a tropical montane environment. Development of the headwaters of the Rio Chagres is minimal and is mostly contained to the Rio Piedras tributary. We collected eight sediments from small tributaries to determine sediment generation on steep hillslopes using cosmogenic (super 10) Be. We collected nine sediment samples at major tributary junctions down the drainage network to determine the spatial distribution of sediment generation rates. A sediment sample taken from the mouth of the Rio Chagres, at Lake Alhajuela, provides an integrated sediment yield estimate from the entire basin. Since the slopes of the Rio Chagres basin are steep, sediment delivery from the hillslopes to the river is by a combination of landslides and diffusive hillslope processes. To understand better the sediment delivery processes we analyzed additional grain sizes for eight samples. Preliminary results from two samples collected from the Rio Chagres at the confluence of Rio Piedras and the confluence of the Rio Chagricito suggest basin wide erosion rates of 80+ or -11 and 70+ or -9 mm ky (super -1) , respectively. These values are similar to the suspended sediment yield data, which can be interpreted as an average basin erosion rate of 95 mm ky (super -1) . These preliminary results suggest that the mostly undisturbed tropical Rio Chagres basin is supplying sediment at similar rates as the long-term basin wide sediment generation. The network analysis of (super 10) Be provides natural rates of sediment yield with which to compare to long records of suspended sediment loads. Such analysis is particularly important in tropical basins that are ecologically fragile and are susceptible to human disturbance.

Our results document the existence of three chemical processes that probably occur in large icy satellites as a result of high pressure hydrothermal processing: (1) the formation of low-density hydrated silicates, (2) the alloying of iron and sulfur to form FeS-dominated cores, and (3) the instability of organic material relative to carbonates. We construct new internal models of the thermal and structural state of Ganymede, and infer that the magnetic field of this body arises from convection within a mostly iron sulfide core. Simple thermochemical calculations are conducted to further explore the likely effects of composition and oxygen fugacity on the high pressure chemistry undergone by organic material within icy satellites. Both experimental and calculated results show that primordial organics are likely to have been largely oxidized to carbonates through hydrothermal processing early in Ganymede"s history, potentially sterilizing Ganymede's H (sub 2) O layer.

As a result, two new local meteoric water lines were defined for the study area. Isotopic analyses of groundwater samples from over 200 springs and wells indicate that the main source of water to the Batinah coastal alluvial aquifer is high-altitude rainfall from the adjacent Jabal Akhdar Mountains, originating from a combination of northern and southern moisture sources. The groundwater recharged at high-altitude forms two plumes of water which is depleted in the heavy isotopes super(18)O and super(2)H and stretches from the mountains across the coastal plain to the sea, thereby retaining a chemical homogeneity horizontally and vertically down to a depth exceeding 300 m. In contrast, in areas adjacent to these two plumes the alluvial aquifer is geochemically stratified. Near the coast, saline intrusion results in abrupt changes in chloride concentrations and isotope values.

One reason for emphasis on the study of individual trace elements has been the difficulty of measuring their concentration against a background of more abundant dissolved sea salts. Now that many of these methodological problems have been addressed, we are discovering relationships between the oceanic distribution and concentration of trace elements and variations in biological productivity, geological activity, weather and climate, and other significant environmental effects. (Note: A number of trace elements have been considered as potential limiting nutrients controlling oceanic productivity.

AN - 72135994; 12351155 AB - We are working to understand possible human health effects from exposure to heterocyclic amines that are formed in meat during cooking. Laboratory-cooked beef, pork, and chicken are capable of producing tens of nanograms of MeIQx, IFP, and PhIP per gram of meat and smaller amounts of other heteroyclic amines. Well-done restaurant-cooked beef, pork, and chicken may contain PhIP and IFP at concentrations as high as tens of nanograms per gram and MeIQx at levels up to 3 ng/g. Although well-done chicken breast prepared in the laboratory may contain large amounts of PhIP, a survey of flame-grilled meat samples cooked in private homes showed PhIP levels in beef steak and chicken breast are not significantly different (P=0.36). The extremely high PhIP levels reported in some studies of grilled chicken are not seen in home-cooked samples.Many studies suggest individuals may have varying susceptibility to carcinogens and that diet may influence metabolism, thus affecting cancer susceptibility. To understand the human metabolism of PhIP, we examined urinary metabolites of PhIP in volunteers following a single well-done meat exposure. Using solid-phase extraction and LC/MS/MS, we quantified four major PhIP metabolites in human urine. In addition to investigating individual variation, we examined the interaction of PhIP with a potentially chemopreventive food. In a preliminary study of the effect of broccoli on PhIP metabolism, we fed chicken to six volunteers before and after eating steamed broccoli daily for 3 days. Preliminary results suggest that broccoli, which contains isothiocyanates shown to induce Phases I and II metabolism in vitro, may affect both the rate of metabolite excretion and the metabolic products of a dietary carcinogen. This newly developed methodology will allow us to assess prevention strategies that reduce the possible risks associated with PhIP exposure.

AN - 72133371; 12351150 AB - 2-Amino-1-methyl-6-phenylimidazo[4,5-b]pyridine (PhIP), a mutagen/carcinogen belonging to the class of heterocyclic amines (HCAs) found in cooked meats, is a known rat mammary gland carcinogen. To gain insight into the genomic alterations associated with PhIP-induced carcinogenesis, we used comparative genomic hybridization (CGH) to examine chromosomal abnormalities in rat mammary gland carcinomas induced by PhIP. The alterations were compared to those induced by 7,12-dimethylbenz[a]anthracene (DMBA), a potent and well-studied mammary carcinogen. All six PhIP-induced carcinomas examined by CGH showed losses in the same specific regions of chromosomes 2, 3, 11, 18, and X, whereas three carcinomas induced by DMBA showed no consistent patterns of chromosomal gain or loss. This indicates that PhIP has a recognizable cytogenetic signature in rat mammary gland carcinomas.

AN - 72132782; 12351147 AB - N-oxidation by cytochrome p450 enzymes is an initial step in the metabolic activation of aromatic amine compounds. Once metabolized, these compounds are converted to DNA-reactive species which can exhibit potent mutagenic and/or carcinogenic activity. The precise mechanism of p450 enzyme oxidation is not completely understood, although various theories, involving either one-electron transfer, two-electron transfer or addition-rearrangement, have been debated. In previous studies, selection of the most probable mechanism has been based on consideration of Hückel theory charge distribution calculations and experimentally-derived enzyme metabolism data. This approach can now be improved by incorporating contemporary, ab initio quantum chemical methods to accurately determine the chemical properties of p450 aromatic amine substrates. In this work, we have re-examined the feasibility of three proposed p450 oxidation mechanisms by comparing the experimental oxidation yields and rates of 1-naphthylamine (1-NA), 2-naphthylamine (2-NA) and 2-aminofluorene (2-AF). This data has then been analyzed with respect to ab initio-calculated charge distributions and energies of reactants, oxidation products and proposed intermediates. Our analysis of theoretical and experimental data indicates that the one-electron model is more consistent with oxidation rate data for 1-NA, 2-NA, and 2-AF. We therefore conclude, in contrast to earlier studies, that the one-electron mechanism is more likely to be the pathway for p450-catalyzed aromatic amine oxidation.

The target gene, bssA, codes for the alpha -subunit of benzylsuccinate synthase. The primer-probe set for real-time PCR was based on consensus regions of bssA from four denitrifying bacterial strains; bssA sequences for two of these strains were determined during this study. The method proved to be sensitive (detection limit ca. 5 gene copies) and had a linear range of >7 orders of magnitude. We used the method to investigate how gasohol releases from leaking underground storage tanks could affect indigenous toluene-degrading bacteria. Microcosms inoculated with aquifer sediments from four different sites were incubated anaerobically with BTEX (benzene, toluene, ethylbenzene, and xylenes) and nitrate in the presence and absence of ethanol. Overall, population trends were consistent with observed toluene degradation activity: the microcosms with the most rapid toluene degradation also had the largest numbers of bssA copies. In the microcosms with the most rapid toluene degradation, numbers of bssA copies increased 100- to 1000-fold over the first 4 days of incubation, during which time most of the toluene had been consumed. These results were supported by slot blot analyses with unamplified DNA and by cloning and sequencing of putative bssA amplicons, which confirmed the real-time PCR method's specificity for bssA. Use of a companion real-time PCR method for estimating total eubacterial populations (based on 16S rDNA) indicated that, in some cases, ethanol disproportionately supported the growth of bacteria that did not contain bssA. The real-time PCR method for bssA could be a powerful tool for monitored natural attenuation of BTEX in fuel-contaminated groundwater. To our knowledge, this is the first reported molecular method that targets anaerobic, hydrocarbon-degrading bacteria based on a catabolic gene.

This paper assesses the extent to which particulate organic carbon (POC) transport to the ocean's interior can be predicted from primary production or export flux. Relationships between POC flux and depth are generally described by a uniform power law or rational decrease with depth, scaled to new or total primary production of POC. These relationships are studied through a review of parameters derived from (super 14) C uptake experiments, regional remote sensing, (super 234) Th studies, nitrogen balances, and sediment trap records. Ocean regions considered include sites studied by the Joint Global Ocean Flux Study, Hawaii Ocean Time-series, and Bermuda Atlantic Time-series Study programs and the Southern Ocean and involve observed and radiochemically corrected flux to depth. The paper demonstrates regional variability in the efficiency of the biological pump to transport organic carbon from surface waters to the ocean's interior. (modified journ. abst.)

Those results may be due to (a) confounding unaddressable by any county-level ('ecological') study design, or (b) county-level factors such as Rn/smoking or age/radon correlations or exposure misclassifications from the use of disparate data sources. Possibilities (b) were addressed by comparing age-specific LCM rates for white women in 2821 U.S. counties who died in 1950-54 at age 40+ ( similar to 11% of whom ever smoked), or at age 60+ ( similar to 5% of whom ever smoked), to county Rn levels newly estimated from U.S. Rn, climatic and geological-survey data. Significant negative LCM v Rn trends were found for both age groups, after adjusting for age and subsets of 21 county-level socioeconomic, climatic and other factors. Negative trends were largest for counties with less than or equal to 100 Bq m super(-3) Rn (p less than or equal to 0.00087; 420 analyses). Adjusted relative risk (RR sub(adj)) for LCM was significantly elevated (1 150 Bq m super(-3) v 65-100 Bq m super(-3) Rn, most involving adjustment for climate- and education-related factors likely to have influenced exposure to indoor air contaminants such as Rn and cigarette smoke. Though inconclusive due to potential ecological-fallacy-related confounding that could not be controlled, results from this ecological study are most consistent with a U-shaped dose-response relationship between 1950-54 LCM risk and U.S. residential radon in white women who predominantly never smoked.

AN - 71977330; 12160888 AB - Adaptive response is a term used to describe the ability of a low, priming dose of ionizing radiation to modify the effects of a subsequent higher, challenge dose, but it has been observed to be highly variable in both presence and magnitude. To examine this variability, 10 human lymphoblastoid cell lines were screened for adaptability to 137Cs radiation by determining the frequency of micronuclei in binucleated cells. Of these, six adapted, three did not adapt and one was synergistic. The assay was then repeated on each of the cell lines to test for reproducibility. Five cell lines showed the same result both times; four of these adapted and one did not. To determine whether fluctuations in the cell cycle distribution in the irradiated population of cells could alter the adaptive response, and therefore explain some of the observed variability, two of the cell lines were tested for adaptation after enriching the population, by synchronization, for a given cell cycle stage. In both cell lines, the direction of the response was altered when the distribution of cells within the cell cycle was changed, suggesting that the adaptive response can be affected by cell cycle stage at the time of irradiation.

Above the eastern portion of the Wadati-Benioff zone however, there is a distinct lack of volcanism (the Denali volcanic gap). We observe high Poisson's ratio values (0.29-0.33) over the entire length of the Alaskan subduction zone mantle wedge based on regional variations of Pn and Sn velocities. High Poisson's ratios at this depth (40-70 km), adjacent to the subducting slab, are attributed to melting of mantle-wedge peridotites, caused by fluids liberated from the subducting oceanic crust and sediments. Observations of high values of Poisson's ratio, beneath the Denali volcanic gap suggest that the mantle wedge contains melted material that is unable to reach the surface. We suggest that its inability to migrate through the overlying crust is due to increased compression in the crust at the northern apex of the curved Denali fault.

AN - 71933780; 12137994 AB - A decontamination method has been developed using a single reagent that is effective both against chemical warfare (CW) and biological warfare (BW) agents. The new reagent, "L-Gel", consists of an aqueous solution of a mild commercial oxidizer, Oxone, together with a commercial fumed silica gelling agent, Cab-O-Sil EH-5. L-Gel is non-toxic, environmentally friendly, relatively non-corrosive, maximizes contact time because of its thixotropic nature, clings to walls and ceilings, and does not harm carpets or painted surfaces. The new reagent also addresses the most demanding requirements for decontamination in the civilian sector, including availability, low maintenance, ease of application and deployment by a variety of dispersal mechanisms, minimal training and acceptable expense. Experiments to test the effectiveness of L-Gel were conducted at Lawrence Livermore National Laboratory and independently at four other locations. L-Gel was tested against all classes of chemical warfare agents and against various biological warfare agent surrogates, including spore-forming bacteria and non-virulent strains of real biological agents. Testing showed that L-Gel is as effective against chemical agents and biological materials, including spores, as the best military decontaminants.

Scanning Electron Microscopy and Energy Dispersive X-ray spectroscopic analysis were performed to identify the morphology and the bulk chemical composition. Glow-Discharge Mass Spectrometry and X-ray Diffraction analyses were also used to characterize the bulk chemical composition and crystalline structure of the deposits. In addition, X-ray photoemission and X-ray photoabsorption spectra for the deposits were compared to a series of Mn compounds to model and aid quantification of the constituents. Results reveal a mixture of Ca-sulfate, Mn-phosphate and Mn-oxide in the bulk of the deposits and a mixture of Mn-sulfate, Mn-phosphate and Mn-oxide on the surface of the deposits.

AN - 85354629; pmid-12186021 AB - Recently, it was shown that the time-reversal operator for a single, small spherical scatterer could have up to four distinguishable eigenstates [Chambers and Gautesen, J. Acoust. Soc. Am. 109, 2616-2624 (2001)]. In this paper, that analysis is generalized for scatterers of arbitrary shape and larger size. It is shown that the time-reversal operator may have an indefinitely large number of distinguishable eigenstates, with the exact number depending on the nature of the scatterer and the geometry of the time-reversal mirror. In addition, the case of a multiple number of well-separated scatterers is investigated, with the result that the total spectrum is the direct combination of the eigenstates associated with each scatterer. As an example, the singular value spectrum of the time-reversal operator for a linear array is calculated explicitly for bubbles and hard rubber spheres of finite size. Both resonance peaks and apparent crossing points can be observed in the spectrum as the size of the scatterer increases.

The distribution and oxidation state of arsenic (As) and selenium (Se) were also determined. The soil used in this study was formed from pyritic shale parent materials on the east side of the California Coast Range. Synchrotron-based X-ray fluorescence microprobe (mu -XRF) was used to generate elemental distribution maps of soil thin sections. Using the elemental distribution maps and optical micrographs, distinct mineral aggregates of iron oxide and iron sulfate were identified throughout the top horizon of the soil. These aggregates range in size from 10 to 100 mu m in diameter and can be found only a few micrometers apart. The As and Se concentrations in the iron oxide aggregates were 5-10 times the concentrations in the iron sulfate aggregates and the weathered shale matrix. This suggests that the As and Se become preferentially associated with iron oxides during the weathering process. Using a focused micron-sized beam, Fe, As, and Se X-ray absorption spectroscopy (XAS) data were collected from the sub-millimeter soil aggregates. The micro-extended X-ray absorption fine structure (mu -EXAFS) spectrum collected from the iron oxide aggregate revealed that its mineralogy was a combination of ferrihydrite (>50%) and goethite. The mu -EXAFS spectra from the iron sulfate region suggest that these aggregates contain jarosite. Using micro-X-ray absorption near edge spectroscopy (mu -XANES), oxidation states of the As and Se were determined. Arsenic was present in the iron oxide aggregate as As(V). Selenium was present in the soil as both Se(IV) and Se(VI), with a higher percentage of Se(VI) in the jarosite aggregate than the iron oxide aggregate. These results provide direct evidence of the distribution, oxidation states, and speciation of As and Se in the solid phase of an unaltered native soil. Information on the weathering and geochemistry of the pyritic materials, and the associated arsenic and selenium is useful for predicting the pedogenic processes of acid sulfate soils and the long-term fate of newly exposed pyritic materials (e.g., mine tailings and drained wetlands).

These moraines, deposited during the Mount Waskey advance, are several kilometers beyond modern glacier termini, and approximately 80 km upvalley of the late Wisconsin Ahklun Mountains ice cap terminal moraine. Eleven cosmogenic (super 10) Be and (super 26) Al exposure ages on moraine boulders, combined with radiocarbon ages from a lake core upvalley of a moraine deposited during the Mount Waskey advance, suggest that the advance culminated between 12.4 and 11.0 ka, sometime during, or shortly following, the Younger Dryas event (ca. 12.9-11.6 ka). We believe that the Mount Waskey advance was a consequence of cooling during the Younger Dryas. These data further strengthen emerging evidence for Younger Dryas-age cooling of the North Pacific region.

While evaluating this system off the Pacific coast of Baja California, we discovered Ba depletion greater than 60% in surface waters over tens of kilometers. Observed Ba abundance is among the lowest reported in any ocean water. No corresponding depletion was seen in Sr, which strongly suggests that acantharians are not the primary source of biogenic Ba in these surface waters.

This paper addresses hydrogeological issues at the 241-SX tank farm, especially focusing on Tank SX-108, which is one of the highest heat load, supernate density and ionic strength tanks at Hanford and a known leaker. The behavior of contaminants in the unsaturated zone near SX-108 is determined by an interplay of multiphase fluid flow and heat transfer processes with reactive chemical transport in a complex geological setting. Numerical simulation studies were performed to obtain a better understanding of mass and energy transport in the unique hydrogeologic system created by the SX tank farm. Problem parameters are patterned after conditions at Tank SX-108, and measured data were used whenever possible. Borrowing from techniques developed in geothermal and petroleum reservoir engineering, our simulations feature a comprehensive description of multiphase processes, including boiling and condensation phenomena, and precipitation and dissolution of solids. We find that the thermal perturbation from the tank causes large-scale redistribution of moisture and alters water seepage patterns. During periods of high heat load, fluid and heat flow near the tank are dominated by vapor-liquid counterflow (heat pipe), which provides a much more efficient mechanism than heat conduction for dissipating tank heat. The heat pipe mechanism is also very effective in concentrating dissolved solids near the heat source, where salts may precipitate even if they were only present in small concentrations in ambient fluids. Tank leaks that released aqueous fluids of high ionic strength into the vadose zone were also modeled. The heat load causes formation dry-out beneath the tank, which is accompanied by precipitation of solutes. These may become remobilized at a later time when tank temperatures decline and previously dried out regions are rewetted. Simulated temperature and moisture distributions compare well with borehole measurements performed in 2000. The temperature maximum observed beneath Tank SX-108 can be explained from past thermal history of the tank; it is not necessary to invoke heat generation from leaked radioactive contaminants. A novel composite medium model is used to explore effects of moisture tension-dependent anisotropy, which is shown to have important impacts on fluid flow and solute transport in the Hanford sediments.

These connections may be nearing their fatigue limit and will require increased inspection and repair over the next 10-20 years. The Winchester Bridge on Interstate 5 in Roseburg, Ore., required the extensive replacement of connection details because of fatigue crack growth. This report describes the results of a study to assess the loading conditions for the connection details on the Winchester Bridge. Finite-element modeling methods were used to characterize the structure, on both a global and local level. The global model provided the boundary conditions for the local model of the connection details. The local model included the effects of rivet preload and friction. Finite-element analysis results were validated by hand calculation. The analysis showed significant variation in connection detail stress range, depending on the detail's longitudinal and lateral location.

Rivers with point sources for super(129)I in their watersheds are drastically affected, while all rivers sampled show evidence for atmospherically transported super(129)I from the world's major nuclear fuel reprocessing facilities. Varying mixtures of oceanic cyclic salt and soil-derived iodine account for the observed spatial variation in iodine concentrations. A comparison of super(129)I concentrations in river and rainwater reveals concentration effects due to evapotranspiration.

We performed direct CO sub(2) injection simulations in both one-dimensional box-diffusion and three-dimensional ocean general circulation models. The 1-D model results for ocean carbon retention accord with the 3-D model results, especially in the Pacific basin and at shallower depths. In the 1-D model, carbon retention in the ocean is directly related to both the injection depth and the Delta super(14)C of carbon at the injection location. However, in the 3-D model, depth, but not radiocarbon, provides a relatively good prediction of carbon retention. This suggests that the expected time for a water parcel to return to the surface is closely related to its depth and not in general to the time since last at the surface.

AN - 71896399; 12113762 AB - Studies of other transgenic assays have shown that time after treatment is a very important variable in the analysis of mutation frequencies but that eventually a plateau frequency is reached, indicating that the mutations are neutral. This neutrality is very important for the design of both experiments and testing protocols. Here we show that the phiX174 am3, cs70 transgene gives qualitatively similar results to the other transgenes studied after exposure of the mice to N-ethyl-N-nitrosourea. In the small intestine, the mutant frequency induced by an acute dose did not change significantly from 10 to 70 days post-treatment, indicating that the mutations induced are, indeed, neutral. Likewise, the mutant frequency increased linearly with duration of exposure to ENU at a constant rate. Mutant frequencies obtained were 10 times higher from the chronic exposure than produced by a nearly lethal acute dose. As in previous comparisons of a transgene and the endogenous Dlb-1 locus in the small intestine, the chronic exposure was much more effective at increasing the sensitivity of the transgene than of the endogenous gene. The Dlb-1 locus shows more complex kinetics in this strain, as in others, with mutations initially accumulating at a slower rate, indicating a differential repair of genetic damage.

These cosmogenic nuclides demonstrate that Australian granite, exposed and sampled at 10 sites along a transect from the Eyre Peninsula (33 degrees S) to the Kakadu area in the Northern Territory (14 degrees S), has in some places eroded only decimeters over the past million years. However, nuclide activities are not saturated in any of the 61 exposed samples we analyzed, mandating that the surfaces we sampled are losing mass, albeit slowly, over time. Such mass loss indicates that inselbergs are dynamic landforms, confounding the assignment of discreet ages to inselberg surfaces. Nevertheless, the differential between slow rates of erosion measured on the very stable uppermost parts of these landforms and the more rapid rates measured below their flanks and below the adjacent grus-covered planes suggests that the forms of many large inselbergs, which stand meters to tens of meters high, must be at least Tertiary in age and possibly much older. Activities of (super 10) Be and (super 26) Al in 61 exposed Australian samples range from 5.1+ or -0.1X10 (super 6) to 5.3+ or -0.6X10 (super 5) atoms.g (super -1) and 2.1+ or - 0.1X10 (super 7) to 3.4+ or -0.5X10 (super 6) atoms.g (super -1) , respectively (normalized to sea level, at latitudes of >60 degrees , using only neutron scaling). Activities of (super 10) Be and (super 26) Al in seven shielded samples (3.5-13 m below the surface) are much lower, ranging from 3.4 + or - 0.2X10 (super 4) to 7.0+ or -0.1X10 (super 4) atoms.g (super -1) and 1.6+ or -0.1 X 10 (super 5) to 2.8+ or - 0.2X10 (super 5) atoms.g (super -1) , respectively. (super 26) Al/ (super 10) Be ratios of exposed samples range from 3.89+ or -0.19 to 6.29 + or - 0.82. If 2sigma uncertainty ranges and a nominal sea-level, high-latitude (super 10) Be-production rate of 5.17 atoms.g (super -1) .yr (super -1) are considered, ratio data for all but one surface sample are consistent with continuous surface or near-surface exposure and/or erosion. Rock surfaces farther north in Australia, where the climate is more humid, have lower nuclide activities; thus, we infer that surface stability is inversely related to mean annual precipitation. From 61 exposed samples, we calculated maximum limiting, single-nuclide, model erosion rates of 0.3+ or -0.1 to 5.7+ or -1.0 m/m.y. and minimum limiting, single-nuclide, model exposure ages of 105+ or -16 to 1310+ or -190 ka (by assuming a sea-level, high-latitude (super 10) Be-production rate of 5.17 atoms.g (super -1) .yr (super -1) ). Seven shielded samples, in which the nuclide inventory is muon-generated, also have nuclide activities consistent with similarly low rates of erosion but over even longer time scales. It appears that the Eyre Peninsula inselbergs have been and are eroding so slowly that they may well be direct descendents of Cenozoic and perhaps even Mesozoic forms.

Results from Boulder Canyon show that terrace heights above the modern channel (grade) can be divided into: (1) Bull Lake (> or =100 ka; 20-15 m above grade); (2) Pinedale (32-10 ka; 15-4 m above grade); and (3) Holocene age (15 m above grade record Bull Lake deposition. Well-preserved terraces of Pinedale age suggest that the range of terrace height above grade reflects short-term fluctuations in the river profile during periods of rapidly changing stream load and power. Net river incision apparently occurred during transitions to interglacial periods. Soil development and stratigraphic position, along with limited cosmogenic and (super 14) C dating, suggest that approximately 130 ka terraces in Boulder Canyon correlate with the Louviers Alluvium, and that 32 to 10 ka fills in the canyon correlate with the Broadway Alluvium on the adjacent High Plains. Late Pleistocene incision rates ( approximately 0.15 m ka (super -1) ) along Boulder Canyon exceed pre-late Pleistocene incision rates, and are higher than middle to late Pleistocene incision rates ( approximately 0.04 m ka (super -1) ) on the High Plains. This study provides an example of how modern geochronologic techniques allow us to understand better rivers that drain glaciated catchments.

We conducted field and greenhouse experiments to compare the rare heterostyle with a cryptic self-incompatibility system (A. grandiflora) to a common, self-compatible, homostylous, sympatric congener (A. tessellata). Inter-species comparisons of adult plants suggested that in the greenhouse, A. grandiflora balances low floral seed set (seeds per flower) with increased floral output (flowers/plant) and a greater number of flowers per inflorescence. Seed set from active self-, intra- and inter-morph pollinations was high in A. grandiflora, indicating that the cryptic self-incompatibility system does not prevent seed set in the species. In the field, A. grandiflora floral output was only slightly greater than for A. tessellata, and did not fully balance lower floral seed set. Amsinckia tessellata average seed weight was lower than that of A. grandiflora, which, along with the lower number of flowers produced, indicated lower maternal investment per nutlet than for A. grandiflora. Under conditions of unlimited resources, it appears that A. grandiflora fitness is not intrinsically limited when compared to its weedy relative A. tessellata. The differences in nutlet output between A. grandiflora and A. tessellata under field conditions are more likely due to differential responses to extrinsic factors such as competition and pollinator availability.

The survey shows that surface water in the San Diego Bay is clearly enriched in Mn, Ni, Cu, Zn, Cd, and FDOM with respect to the coastal ocean. Trace element enrichment patterns were used to identify bay water as it enters the coastal ocean during tidal pumping. Quantifying the spatial distribution and temporal flux of pollutant trace elements are important steps in understanding coastal biogeochemical processes.

An effective means to survey differences across whole genomes would be highly advantageous for understanding this variation. Here we show that suppression subtractive hybridization (SSH) provides high, representative coverage of regions that differ between similar genomes. Using Helicobacter pylori strains 26695 and J99 as a model, SSH identified approximately 95% of the unique open reading frames in each strain, showing that the approach is effective. Furthermore, combining data from parallel SSH experiments using different restriction enzymes significantly increased coverage compared to using a single enzyme. These results suggest a powerful approach for assessing genome differences among closely related strains when one member of the group has been completely sequenced.

AN - 71940545; 12136519 AB - Molecular targeted radionuclide therapy promises to expand the usefulness of radiation to successfully treat widespread cancer. The unique properties of radioactive tags make it possible to plan treatments by predicting the radiation absorbed dose to both tumors and normal organs, using a pre-treatment test dose of radiopharmaceutical. This requires a combination of quantitative, high-resolution, radiation-detection hardware and computerized dose-estimation software, and would ideally include biological dose-response data in order to translate radiation absorbed dose into biological effects. Data derived from conventional (external beam) radiation therapy suggests that accurate assessment of the radiation absorbed dose in dose-limiting normal organs could substantially improve the observed clinical response for current agents used in a myeloablative regimen, enabling higher levels of tumor control at lower tumor-to-normal tissue therapeutic indices. Treatment planning based on current radiation detection and simulations technology is sufficient to impact on clinical response. The incorporation of new imaging methods, combined with patient-specific radiation transport simulations, promises to provide unprecedented levels of resolution and quantitative accuracy, which are likely to increase the impact of treatment planning in targeted radionuclide therapy.

AN - 71800255; 12055289 AB - Yersinia pestis, the causative agent of bubonic plague, emerged recently (<20000 years ago) as a clone of Yersinia pseudotuberculosis. There is scant evidence of genome diversity in Y. pestis, although it is possible to differentiate three biovars (antiqua, mediaevalis or orientalis) based on two biochemical tests. There are a few examples of restriction fragment length polymorphisms (RFLPs) within Y. pestis; however, their genetic basis is poorly understood. In this study, six difference regions (DFRs) were identified in Y. pestis, by using subtractive hybridization, which ranged from 4.6 to 19 kb in size. Four of the DFRs are flanked by insertion sequences, and their sequences show similarity to bacterial genes encoding proteins for flagellar synthesis, ABC transport, insect toxicity and bacteriophage functions. The presence or absence of these DFRs (termed the DFR profile) was demonstrated in 78 geographically diverse strains of Y. pestis. Significant genome plasticity was observed among these strains and suggests the acquisition and deletion of these DNA regions during the recent evolution of Y. pestis. Y. pestis biovar orientalis possesses DFR profiles that are different from antiqua and mediaevalis biovars, reflecting the recent origins of this biovar. Whereas some DFR profiles are specific for antiqua and mediaevalis, some DFR profiles are shared by both biovars. Furthermore, the progenitor of Y. pestis, Y. pseudotuberculosis (an enteric pathogen), possesses its own DFR profile. The DFR profiles detailed here demonstrate genome plasticity within Y. pestis, and they imply evolutionary relationships among the three biovars of Y. pestis, as well as between Y. pestis and Y. pseudotuberculosis.

Crustal detachment has unroofed the ca. 8 Ma Cordillera Blanca batholith, now the backbone of the highest mountain range in Peru. Large-magnitude slip along the fault was thermally enhanced by emplacement of the batholith, the penultimate magmatic event prior to flattening of the Nazca slab. However, extensional models based on arc magmatism and crustal thickening alone do not adequately explain the scale or structural asymmetry of a series of young, deep-seated, west-dipping normal faults across Peru. Here we show that the onset of detachment faulting coincided with subduction of the aseismic Nazca Ridge and consequent flattening of the Nazca slab. We propose that slab buoyancy from ridge subduction triggered extensional collapse of the prethickened continental crust, and that this buoyancy drove footwall uplift that exceeds basin subsidence. The west-dipping asymmetry of late Cenozoic extensional faults in Peru may be controlled by a preexisting crustal anisotropy (older thrusts), and/or formation of Riedel-like shears kinematically linked to the flat Nazca slab.

Cosmogenic nuclide-based models suggest that the Iron and Granite Mountains generate 0.11-0.13 and 0.082-0.097 m (super 3) of sediment per year per meter of rangefront, respectively. The sediment moves down the piedmont in an active transport layer (ATL), which is 20 to 30 cm thick (based on visual observations, measurements of depth to a buried B-horizon, cosmogenic nuclide data, and maximum ephemeral channel depths). Sediment in this layer is well-mixed vertically and horizontally on the 10 (super 2) year time scale, indicating that the small ephemeral channels, which dominate the piedmont surface migrate quickly. Interpretive models of increasing nuclide activities at depth in two pits suggest steady sediment deposition on the piedmont (at rates between 17-21 and 38-45 m Ma (super -1) ) until the late Pleistocene epoch, when a discontinuity to markedly lower nuclide activities in the isotopically well-mixed active transport layer suggests that deposition stopped, a significant change in piedmont behavior. Nuclide activities in 10 amalgamated surface samples, each collected along a different 4-km-long transect, increase steadily away from the mountain front. Thus, we infer that sediment is uniformly dosed by cosmic rays as it is transported down the Iron and Granite Mountain piedmonts. Interpretive models suggest that long-term average sediment speeds down the Iron and Granite Mountain piedmonts are a few decimeters to a meter per year.

From the measurements, we determine long-term, time-integrated rates of upland sediment generation (81+ or -5 g m (super -2) year (super -1) ) and bedrock equivalent lowering (30+ or -2 m Ma (super -1) ) consistent with other estimates for regions of similar climate, lithology, and topography. In a small ( approximately 8 km (super 2) ), upland sub-basin, differences in nuclide concentrations between bedrock outcrops and hillslope colluvium suggest weathering of bedrock beneath a colluvial cover is a more significant source of sediment (40X10 (super 4) kg year (super -1) ) than weathering of exposed bedrock surfaces (10X10 (super 4) kg year (super -1) ). Mixing models constructed from nuclide concentrations of sediment reservoirs identify important sediment source areas. Hillslope colluvium is the dominant sediment source to the upper reaches of the sub-basin channel; channel cutting of alluvial terraces is the dominant source in the lower reaches. Similarities in nuclide concentrations of various sediment reservoirs indicate short sediment storage times (<10 (super 3) years). Nuclide concentrations, measured in channel sediment from tributaries of Yuma Wash and in samples collected along the length of the Wash, were used to construct mixing models and determine sediment sources to the main stem channel. We find an exponential decrease in the channel nuclide concentrations with distance downstream, suggesting that as much as 40% of sediment discharged from Yuma Wash has been recycled from storage within basin fill alluvium. Sediment generation and denudation rates determined from the main stem are greater (25%) than rates determined from upland sub-basins suggesting that, currently, sediment may be exported from the basin more quickly than it is being generated in the uplands. Independence of nuclide concentration and sediment grain size indicates that channels transport sediment in discrete pulses before rapidly depositing poorly sorted material, suggesting that differences in transport times for different size materials are minimal.

We demonstrate the ability of an algebraic multigrid algorithm (AMG) to efficiently solve the large, sparse systems of equations that result from computational models of ground water flow and transport in large and complex domains. Unlike geometric multigrid methods, this algorithm is applicable to problems in complex flow geometries, such as those encountered in pore-scale modeling of two-phase flow and transport. We integrated AMG into MODFLOW 2000 to compare two- and three-dimensional flow simulations using AMG to simulations using PCG2, a preconditioned conjugate gradient solver that uses the modified incomplete Cholesky preconditioner and is included with MODFLOW 2000. CPU times required for convergence with AMG were up to 140 times faster than those for PCG2. The cost of this increased speed was up to a nine-fold increase in required random access memory (RAM) for the three-dimensional problems and up to a four-fold increase in required RAM for the two-dimensional problems. We also compared two-dimensional numerical simulations of steady-state transport using AMG and the generalized minimum residual method with an incomplete LU-decomposition preconditioner. For these transport simulations, AMG yielded increased speeds of up to 17 times with only a 20% increase in required RAM. The ability of AMG to solve flow and transport problems in large, complex flow systems and its ready availability make it an ideal solver for use in both field-scale and pore-scale modeling.

This study compares abstracted, homogeneous representations of porosity and permeability, mineral surface areas and distributions, to discrete distribution representation of these same properties. Discretization was accomplished by high-resolution (ca. 1 mu m super(2)) characterization of fractured tuffaceous rock from Yucca Mountain, Nevada, using optical microscopy and X-ray fluorescence spectroscopy. A sample area of 10 super(6) mu m super(2) was mapped in detail, and the resulting element and porosity maps were digitized. The domain was decomposed into 12,208 cells that were 8.77 x 10 super(-6) m on a side. Simulations were conducted in which a dilute fluid enters the discretized porous medium at modest flow rates. Simulation results using a discrete mineral distribution point to the conclusion that slow flow rates, in which fluid residence times are on the order of days, provide fluid composition results that are very similar to those obtained from the homogeneous mineral distribution representation. At higher flow rates, where fluid residence times are on the order of hours, contrasts in fluid composition persist throughout the flow domain. The results demonstrate that the fluid composition characteristics in the homogeneous and discrete mineral representations will be similar only when the bulk average contact times for the individual mineral phases along the flow paths are approximately equivalent (within a few percent) for the two cases.

A novel IS10-like element, IS1330, uncovered by this technique was found to be uniquely present in high copy numbers among the highly pathogenic Y. enterocolitica 1B strains, while a single copy of the element was found in the low pathogenic Ye biogroup 4 serotype O:3 strain. The 1321-bp repetitive element has 19-bp imperfect inverted terminal repeats and is bracketed by a 10-bp duplication of the target sequence. The predicted transposase shares high homology with the IS10 open reading frame of the large virulence plasmid pWR501, of Shigella flexneri, with IS10 transposase of Salmonella typhi, and with IS1999 (tnpA) of Pseudomonas aeruginosa. The IS1330 tnp gene is transcribed in vitro and in vivo in HeLa cells. At least one copy of IS1330 flanks the recently described chromosomal type III secretion cluster in Y. enterocolitica WA-314, O:8, and future studies should shed light on whether this novel transposase mediates transposition events in highly pathogenic Y. enterocolitica strains, thus enhancing the genetic plasticity of this species.

AN - 71972770; 12153019 AB - RDX (hexahydro-1,3,5-trinitro-1,3,5-triazine) is a nitramine explosive that has contaminated soil and groundwater at military installations throughout the US. Although anaerobic RDX metabolism has been reported, the process is not well understood, as past studies have typically involved complex, undefined media with multiple potential electron donors and acceptors. In this study, bacteria enriched from RDX-contaminated aquifer sediments consumed RDX in a defined, bicarbonate-buffered, anaerobic medium containing hydrogen as the sole electron donor and RDX as a potential electron acceptor and sole nitrogen source. RDX was not consumed in live controls that did not contain hydrogen. Transient formation of mononitroso- and dinitroso-RDX metabolites (hexahydro-1-nitroso-3,5-dinitro-1,3,5-triazine and hexahydro-1,3-dinitroso-5-nitro-1,3,5-triazine, respectively) was documented by liquid chromatography-mass spectrometry. However, studies with 14C-labeled RDX suggested that mineralization to carbon dioxide was negligible (<2%), which is consistent with cometabolic transformation. Several lines of evidence suggest that the RDX-transforming bacteria under study were homoacetogens, including correlations between RDX consumption and acetate production. Methanogens were unlikely to be responsible for RDX metabolism, as the presence of 2-bromoethanesulfonate, an inhibitor of methanogenesis, did not appear to affect RDX metabolism. The presence of nitrate reversibly halted RDX metabolism, whereas ammonium had no discernible effect, which implies that: (i) nitrate, which commonly occurs in RDX-contaminated groundwater, may inhibit in situ RDX metabolism, and (ii) although RDX may act as both a nitrogen source and cometabolic electron sink, the latter role predominates, as RDX reduction will proceed regardless of whether or not a more favorable nitrogen source is present.

AN - 71609059; 11955674 AB - Heterocylic amine (HA) compounds formed in the cooking of certain foods have been shown to be bacterial mutagens and animal carcinogens, and may be a risk factor for human cancer. To help explain the variation observed in HA formation under different cooking conditions, we have performed heat-flow simulations and experiments on the pan-frying of beef patties. The simulations involve modeling the heat flow within a meat patty using empirically derived thermal transport coefficients for the meat. The predicted temperature profiles are used to integrate the Arrhenius rate equation to estimate the concentration of HAs formed in the meat. We find that our simulations accurately model experimentally determined temperature profiles, cooking times, HA spatial distributions and total HA formation in patties that are flipped once during the pan-frying process. For patties flipped every 60 s, the simulations qualitatively agree with experiment in predicting reduced cooking times and HA formation relative to the singly-flipped patties. However, the simulations overestimate the effect of rapid flipping on cooking times and underestimate the effect of flipping on total HAs formed. These results suggest that the dramatic reductions in HA formation due to rapid flipping may be due to factors other than the heating process or that there is a critical feature of the flipping process that is not captured in our model.

During the late Quaternary, glaciers advanced at least eight times. By using (super 10) Be and (super 26) Al surface-exposure dating on moraine boulders and scoured bedrock, we determined the timing of glaciation for four of these glacial advances: ca. 54.7-43.2 ka (Borit Jheel glacial stage), ca. 25.7-21.8 ka (Ghulkin I glacial stage), ca. 18.4-15.3 ka (Ghulkin II glacial stage), and ca. 10.8-9.0 ka (Batura glacial stage). For two of the older advances, the Yunz and Shanoz glacial stages, our data set a limit of >60 ka. Although, at present, the uncertainties in dating make it impossible to describe unequivocally the climate processes controlling glaciations in the Hunza Valley, the results suggest that precipitation changes related to oscillations in the Southwest Asian monsoonal system combine with cooling that is broadly associated with Heinrich events to cause glacial advances in this region.

We used the Global Implicit Multicomponent Reactive Transport (GIMRT) code to model the processes occurring in the sediment column (diagenesis, sediment burial, fluid advection, and multicomponent diffusion) and to estimate net seafloor fluxes of solutes. Within the sediment section, the reactions controlling the concentrations of the solutes listed above are organic matter degradation via SO (sub 4) reduction, dissolution of amorphous silica, reductive dissolution of amorphous Fe(III)-(hydr)oxide, and precipitation of calcite, carbonate fluorapatite, and amorphous Fe(II)-sulfide. Rates of specific discharge estimated from pore-water Mg profiles are 2 to 3 mm/yr. At this site the basement hydrothermal system is a source of NH (sub 4) , SiO (sub 2(aq)) , and Ca, and a sink of SO (sub 4) , PO (sub 4) , and alkalinity. Reaction within the sediment column increases the hydrothermal sources of NH (sub 4) and SiO (sub 2(aq)) , increases the hydrothermal sinks of SO (sub 4) and PO (sub 4) , and decreases the hydrothermal source of Ca. Reaction within the sediment column has a spatially variable effect on the hydrothermal flux of alkalinity. Because the model we used was capable of simulating the observed pore-water chemistry by using mechanistic descriptions of the biogeochemical processes occurring in the sediment column, it could be used to examine the physical controls on hydrothermal fluxes of solutes in this setting. Two series of simulations in which we varied fluid flow rate (1 to 100 mm/yr) and sediment thickness (10 to 100 m) predict that given the reactions modeled in this study, the sediment section will contribute most significantly to fluxes of SO (sub 4) and NH (sub 4) at slow flow rates and intermediate sediment thickness and to fluxes of SiO (sub 2(aq)) at slow flow rates and large sediment thickness. Reaction within the sediment section could approximately double the hydrothermal sink of PO (sub 4) over a range of flow rates and sediment thickness, and could slightly decrease (by < or =10%) the size of the hydrothermal source of Ca.

The total water flow from all sampled cold springs was > or =1.8X10 (super 7) m (super 3) /yr draining an area that receives an estimated 2.5X10 (super 7) m (super 3) /yr of recharge, suggesting that sample coverage of the groundwater system was essentially complete. Some of the waters contain magmatic helium with (super 3) He/ (super 4) He ratios as high as 4.5 times the atmospheric ratio, and a magmatic component in the dissolved inorganic carbon (DIC) can be identified in virtually every feature sampled. Many waters have a (super 14) C of 0-5 pmC, a delta (super 13) C near -5 per mil, and contain high concentrations (20-50 mmol/l) of CO (sub 2(aq)) ; but are otherwise dilute (specific conductance = 100-300 mu S/cm) with low pH values between 5 and 6. Such waters have previously escaped notice at Mammoth Mountain, and possibly at many other volcanoes, because CO (sub 2) is rapidly lost to the air as the water flows away from the springs, leaving neutral pH waters containing only 1-3 mmol/l HCO (sub 3) (super -) . The total discharge of magmatic carbon in the cold groundwater system at Mammoth Mountain is approximately 20 000 t/yr (as CO (sub 2) ), ranging seasonally from about 30 to 90 t/day. Several types of evidence show that this high discharge of magmatic DIC arose in part because of shallow dike intrusion in 1989, but also demonstrate that a long-term discharge possibly half this magnitude ( approximately 10 000 t/yr) predated that intrusion. To sustain a 10 000 t/yr DIC discharge would require a magma intrusion rate of 0.057 km (super 3) per century, assuming complete degassing of magma with 0.65 wt% CO (sub 2) and a density of 2.7 t/m (super 3) . The geochemical data also identify a small (<1 t/day) discharge of magmatic DIC that can be traced to the Inyo Domes area north of Mammoth Mountain and outside the associated Long Valley caldera. This research, along with recent studies at Lassen Peak and other western USA volcanoes, suggests that the amount of magmatic carbon in cold groundwaters is important to constraining rates of intrusion and edifice weathering at individual volcanoes and may even represent a significant fraction of the global carbon discharge from volcanoes.

Three of our four trenches, trenches A, B, and C, were excavated across the 1999 Hector Mine rupture; a fourth trench, D, was excavated across a vegetation lineament that had only minor slip at its southern end in 1999. Trenches A-C exposed strata that are broken only by the 1999 rupture; trench D exposed horizontal bedding that is locally warped and offset by faults. Stratigraphic evidence for the timing of an earlier earthquake along the 1999 rupture across Lavic Lake playa was not exposed. Thus, an earlier event, if there was one along that rupture trace, predates the lowest stratigraphic level exposed in our trenches. Radiocarbon dating of strata near the bottom of trenches constrains a possible earlier event to some time earlier than about 4950 B.C. Buried faults revealed in trench D are below a vegetation lineament at the ground surface. A depositional contact about 80 cm below the ground surface acts as the upward termination of fault breaks in trench D. Thus, this contact may be the event horizon for a surface-rupturing earthquake prior to 1999-the penultimate earthquake on the Lavic Lake fault. Radiocarbon ages of detrital charcoal samples from immediately below the event horizon indicate that the earthquake associated with the faulting occurred later than A.D. 260. An approximately 1300-year age difference between two samples at about the same stratigraphic level below the event horizon suggests the potential for a long residence time of detrital charcoal in the area. Coupled with a lack of bioturbation that could introduce young organic material into the stratigraphic section, the charcoal ages provide only a maximum bounding age; thus, the recognized event may be younger. There is abundant, subtle evidence for pre-1999 activity of the Lavic Lake fault in the playa area, even though the fault was not mapped near the playa prior to the Hector Mine earthquake. The most notable indicators for long-term presence of the fault are pronounced, persistent vegetation lineaments and uplifted basalt exposures. Primary and secondary slip occurred in 1999 on two southern vegetation lineaments, and minor slip locally formed on a northern lineament; trench exposures across the northern vegetation lineament revealed the post-A.D. 260 earthquake, and a geomorphic trough extends northward into alluvial fan deposits in line with this lineament. The presence of two basalt exposures in Lavic Lake playa indicates the presence of persistent compressional steps and uplift along the fault. Fault-line scarps are additional geomorphic markers of repeated slip events in basalt exposures.

Hydrogel swelling in response to analyte concentration exerts contact pressure on a deformable conducting diaphragm, producing a capacitance change. Initial results are reported for testing device feasibility. Uncrosslinked PHEMA hydrogel was tested for swelling pressure in response to calcium nitrate tetrahydrate. Diaphragm deflection due to applied air pressure was measured on NiTi-based diaphragms and compared with hydrogel-actuated deflections of the same diaphragms to determine the pressure generating characteristics of the hydrogel. The PHEMA sample exhibited greatest sensitivity in the concentration range 0-0.5 M, generating an average of 110 mN/M/ mu l. The device was incorporated into a passive LC resonant circuit. Resonance frequency was measured as a function of applied air pressure, in the range of pressures generated by hydrogel swelling. Resonance frequency shifted from 66 MHz to 33 MHz over the pressure range 0-32 kPa, corresponding to an estimated average sensitivity of 66 Hz per mu mol of calcium nitrate tetrahydrate over the range 0-0.5 M.

This device provides a new treatment modality that could enable significant improvements in therapeutic stroke outcomes, ultimately improving mortality rates and decreasing morbidity, thereby reducing the cost of rehabilitation and improving the quality of life. Using differential scanning calorimetry (DSC) and dynamic mechanical thermal analysis (DMTA) to define the thermo-mechanical behavior of SMP, we provide useful information about the polymer structure, conditions for device actuation, and an estimate of the recovery forces the device is capable of delivering during the transition between it's straight and coiled shape. In addition, experimental determination of the maximum amount of pressure and force against which the microactuator coil can hold a clot is reported. The results of these tests establish that the device can successfully hold a clot against forces and pressures well above those expected in physiological systems for clot extraction, rendering it as an exciting new technology for treating ischemic stroke.

In vivo strong evidence of aneuploidy and polyploidy induction has been obtained in germ cells, especially in oocytes. More controversial are the data on the aneugenicity of griseofulvin in somatic cells. In this paper we provide evidence that GF induces non-disjunction and cell cycle delay in bone marrow cells of orally treated mice. Adult female mice were administered olive oil suspensions of 200, 666 or 2000 mg/kg GF by gavage and killed 18 or 24 h later. To minimize animal-to-animal variation in the absorption and distribution of GF, mice were fasted from the time of GF administration to the time of killing. Two hours before treatment the animals were s.c. implanted with a bromodeoxyuridine tablet to obtain differential chromatid staining and to determine the number of divisions after GF treatment for each metaphase. Mitostatic effects of GF were assessed by the relative proportions of first, second and third generation metaphases and the average generation time (AGT) method. A statistically significant increase with respect to the control AGT value was observed after treatment with 666 and 2000 mg/kg, suggesting that GF, as already shown in meiosis, interfered with cell cycle progression. Hyperploidy was scored in second generation metaphases. Eighteen hours after treatment, the frequencies of hyperploid cells were significantly (P < 0.05) higher in all GF-treated groups than in their matched control group. The effect was not dose-dependent. No further increase in aneuploidy was observed at 24 h, suggesting that cells overcoming mitotic arrest did not have a higher rate of non-disjunction. No induction of polyploidy was demonstrated. We conclude that GF induces mitotic delay and aneuploidy in mouse bone marrow and suggest that the protocol used to formulate the gavage suspensions and the after-treatment fasting of the animals enhanced the bioavailability of GF to bone marrow cells.

Some of the most promising applications of this approach are presently limited by the rate at which sequences can be analyzed. As a step toward overcoming this limitation, we have investigated the use of photolithography chip technology to perform sequence analyses on amplified small-subunit rRNA genes. The GeneChip (Affymetrix Corporation) contained 31,179 20-mer oligonucleotides that were complementary to a subalignment of sequences in the Ribosomal Database Project (RDP) (B. L. Maidak et al., Nucleic Acids Res. 29:173-174, 2001). The chip and standard Affymetrix software were able to correctly match small-subunit ribosomal DNA amplicons with the corresponding sequences in the RDP database for 15 of 17 bacterial species grown in pure culture. When bacteria collected from an air sample were tested, the method compared favorably with cloning and sequencing amplicons in determining the presence of phylogenetic groups. However, the method could not resolve the individual sequences comprising a complex mixed sample. Given these results and the potential for future enhancement of this technology, it may become widely useful.

This phenomenon might be explained by the co-occurrence of translocations in cells that also contain dicentrics, in which case translocations would be eliminated as a by-product of selection against dicentrics. Alternatively, a fraction of translocations may themselves be lethal. Here we describe our initial approaches to develop mathematical models to test whether the decline in translocation frequencies results from the first, the second, or a combination of these two possibilities. The models assumed that all chromosome exchanges were simple, i.e., were comprised of dicentrics as well as one-way and two-way translocations. Complex aberrations (three or more breaks in two or more chromosomes) were not modeled, nor were fragments or intrachromosomal exchanges (rings, inversions). We tested the models using Monte Carlo simulations, and then we fitted the models to data describing chromosome aberration frequencies induced by a single acute in vitro exposure to 137Cs g rays in human peripheral blood lymphocytes from two donors. Chromosome painting was used to enumerate translocations and dicentrics from 2 to 7 days after exposure. Our results indicate that in donor no. 2, the decline in translocation frequencies occurs as a by-product of selection against dicentrics. However, in donor no. 1, whose cells appeared more radiosensitive than cells from donor no. 2, up to 40% of the one-way translocations may themselves be lethal at high doses, although calculations indicate that two-way translocations do not cause lymphocyte mortality. Individual variation in the probability that translocations are lethal to cells appears to be important, and one-way translocations appear to be lethal more often than two-way translocations. Within the limits of these models, these findings indicate that both postulated mechanisms, i.e. inherent lethality and selection against dicentrics in the same cells, contribute to the loss of both one-way and two-way translocations.

I. Mechanistic insights. AN - 71582713; 11937636 AB - Base excision repair (BER) is a multistep process involving the sequential activity of several proteins that cope with spontaneous and environmentally induced mutagenic and cytotoxic DNA damage. Quantitative kinetic data on single proteins of BER have been used here to develop a mathematical model of the BER pathway. This model was then employed to evaluate mechanistic issues and to determine the sensitivity of pathway throughput to altered enzyme kinetics. Notably, the model predicts considerably less pathway throughput than observed in experimental in vitro assays. This finding, in combination with the effects of pathway cooperativity on model throughput, supports the hypothesis of cooperation during abasic site repair and between the apurinic/apyrimidinic (AP) endonuclease, Ape1, and the 8-oxoguanine DNA glycosylase, Ogg1. The quantitative model also predicts that for 8-oxoguanine and hydrolytic AP site damage, short-patch Polbeta-mediated BER dominates, with minimal switching to the long-patch subpathway. Sensitivity analysis of the model indicates that the Polbeta-catalyzed reactions have the most control over pathway throughput, although other BER reactions contribute to pathway efficiency as well.

AN - 71596596; 11944981 AB - In the course of large-scale mutagenesis studies, we discovered a mutant that provides a new mouse model for human autosomal recessive polycystic kidney disease. Animals homozygous for this mutation, T(2;10)67Gso, present evidence of grossly cystic renal and hepatic tissue at birth and a limited survival time of 3-4 days. The recessively expressed phenotype is associated with inheritance of a reciprocal translocation involving mouse chromosomes 2 and 10. Here we describe the pathology and phenotype of this new mutation. The mapping of the chromosomal breakpoint to the 1.0-cM critical region defined for another mouse autosomal recessive polycystic kidney disease model, juvenile congenital polycystic kidney disease (jcpk), led us to undertake the complementation testing that confirmed T(2;10)67Gso and jcpk are allelic. Because of the strong resemblance between the phenotype associated with these mouse mutations and early childhood polycystic kidney disease, and because of advantages offered by reciprocal translocations for gene mapping and cloning, T(2;10)67Gso should prove a valuable asset for studies concerning this fatal disease.

The maximum fault slip occurs along a pair of low-angle normal faults that have caused significant tectonic denudation of the Tethyan Sedimentary Sequence, resulting in juxtaposition of weakly metamorphosed Paleozoic rocks and Tertiary sedimentary rocks in the hanging wall over amphibolite-facies mylonitic schist, marble, gneisses, and variably deformed leucogranite bodies in the footwall. The footwall of the detachment fault system records a late Miocene intrusive event, in part contemporaneous with top-to-the-west ductile normal shearing. The consistency of the mean shear direction within the mylonitic footwall rocks and its correlation with structurally higher brittle normal faults suggest that they represent an evolving low-angle normal-fault system. (super 40) Ar/ (super 39) Ar data from muscovite and biotite from the footwall rocks indicate that it cooled below 400 degrees C by ca. 9 Ma. Consideration of the original depth and dip angle of the detachment fault prior to exhumation of the footwall yields total slip estimates between 66 and 35 km across the Gurla Mandhata detachment system. The slip estimates and timing constraints on the Gurla Mandhata detachment system are comparable to those estimated on the right-slip Karakoram fault system, to which it is interpreted to be kinematically linked. Moreover, the mean shear-sense direction on both the Karakoram Fault and the Gurla Mandhata detachment system overlap along the intersection line between the mean orientations of the faults, which further supports a kinematic association. If valid, this interpretation extends previous results that the Karakoram Fault extends to mid-crustal depths.

Interpretation of seismic velocities and amplitudes is based on theories of fluid-saturated and partially saturated rocks that have been available since the 1950s. Here we present a new synthesis of the same physical concepts that uses compressional-wave velocities together with shear-wave velocities in a scheme that is much simpler to understand and apply yet yields detailed information about porosity and fluid saturation magnitudes and spatial distribution. The key idea revolves around the fact that the density and the Lame elastic parameter lambda are the only two parameters determining seismic velocities that also contain information about fluid saturation. At low enough frequencies, Gassmann's well-known equations show that the shear modulus is independent of the fluid saturation level. We use these facts to construct saturation-proxy and data-sorting plots from seismic velocity data. The new method does not require reflectivity data, although it can use such information if available. The method can therefore be applied to a wide range of source receiver configurations, including seismic reflection profiling (surface to surface), vertical seismic profiling (well to surface), and cross-well seismic transmission tomography (well to well) since availability of reflection data is not a requirement.

Sediments were characterised using on-board visual description, smear-slides analyses, grain-size composition and magnetic susceptibility (MS) records. Five tephra marker layers, identified as Ko, TR, K2, K3 and K4, were distinguished using petrological, mineralogical and geochemical analyses. Age models were developed by comparing lithological units, tephra stratigraphy and MS records with oxygen isotope curves and with records of biogenic CaCO (sub 3) , opal content, and sediment grain-size composition in three AMS radiocarbon dated Okhotsk cores. This chronological framework allowed us to investigate climate control over the sedimentation regime and productivity, and to clarify the formation times of the lithological and tephra units. The data show that sediment MS variations in the south-eastern area of the glacial Okhotsk Sea arose primarily from volcanic material input. The sedimentation in all other parts of the sea was mainly controlled by the supply of terrigenous material. The cores show a tight correlation between MS, sediment grain size and climate change in the Okhotsk Sea: coarse sediments with a high MS were accumulated during the cold period-oxygen isotope stages (MIS) 2, 4, 6; fine sediments with a low ice-rafted debris (IRD) content and MS were formed in the warm isotope stages. According to the oxygen isotope stratigraphy and radiocarbon data, the Ko, TR, K2, K3 and K4 tephra were deposited at 7.7, 8.0, 26.0 kyr BP, in MIS 4 about 60-70 kyr ago, and near MIS 5.4, respectively. Comparison of tephra mineralogy, petrology, spatial distributions and ages with the history of Kurile-Kamchatka volcanism allows us to identify likely candidates for the tephra source eruptions. The combined use of MS records, tephrochronology and lithological unit sequences provides a detailed basis for Okhotsk Sea sediment stratigraphy.

The first -- oblique convergence between the Nazca and South American plates -- has produced a component of sinistral deformation in the Andean region. Examples include counterclockwise rotation of late Cenozoic intercordilleran basins (e.g., Ayacucho, ca. 9 to 7 Ma), sinistral transtension that partially facilitated emplacement of the Cordillera Blanca batholith (ca. 8 Ma), and oblique sinistral slip along large-scale, active normal faults (e.g., Cordillera Blanca detachment fault, Quiches fault). The second boundary condition involved flattening of the Nazca slab, which at the latitudes studied here (8-13 degrees S), was primarily caused by subduction of the aseismic (hotspot) Nazca Ridge. Plate reconstruction shows that the Nazca Ridge, the leading edge of the flat slab, subducted under the Cordillera Blanca region at ca. 5 Ma, a time coincident with both the cessation of arc magmatism and the onset of detachment faulting. We propose that lithospheric buoyancy from the subducted ridge triggered extensional collapse of pre-thickened continental crust. Detachment faulting nucleated in crust thermally weakened by emplacement of the Cordillera Blanca batholith, the penultimate magmatic event prior to slab flattening. The Andean region is thus dominated by transcurrent and extensional deformation, with contraction isolated to the trench and sub-Andean regions. Many questions remain, such as how slab flattening, and attendant plate coupling, might have affected the partitioning of oblique plate convergence in the overriding plate.

A significant component of this dextral shear is accommodated along the Owens Valley-White Mountains fault system. A recently published kinematic model for the ECSZ suggests that since approximately 1.7 Ma, 15-40% of Owens Valley fault slip was captured by the Deep Springs normal fault and transferred eastward to the Fish Lake Valley fault zone. Based on this model, 1.0-2.8 mm/yr of Owens Valley fault slip continues northward along the White Mountains fault zone (WMFZ) (Lee et al., 2001). New geologic mapping, geomorphic, and geochronologic investigations along the WMFZ shed light on its Quaternary dextral fault slip history and allow us to test this kinematic model. The WMFZ is composed of a network of NNW-striking right lateral strike-slip faults and NNE-striking, primarily W-dipping normal faults that bound the western side of the White Mountains. This fault zone cuts Quaternary coarse- to fine-grain alluvial fan deposits interbedded with tuffaceous sand, partially welded tuff, and Bishop ash. Based on alluvial fan surface morphology, such as terrace height, presence or absence of bar and swale morphology, degree of fan dissection, and degree of desert pavement development, we have identified three Quaternary alluvial fan surfaces of distinct ages. Tectonic geomorphic features such as linear fault scarps, closed depressions, ponded alluvium, offset alluvial fans, deflected drainages, and shutter ridges indicate that dextral faults cut these alluvial surfaces. Drainages and shutter ridges show offsets that range from 5 to 370 meters. 10Be cosmogenic radionuclide (CRN) dating methods used on in situ boulders demonstrate that the age of the oldest fan surface is approximately 200 ka. Maximum offset of this oldest fan surface is approximately 370 m, yielding a late Pleistocene slip rate of approximately 1.8 mm/yr. Therefore, the slip rate estimate determined in this study is consistent with the model proposed for the WMFZ.

During the 1906 San Francisco earthquake, the ground ruptured along the northeastern edge of the Vedanta marsh where historical offset measurements near the site were about 5 m. Five trenches were excavated across the fault during the 2001 field season. The main fault zone consists of a 2-m-wide zone of upward-branching fault splays within the marsh stratigraphy. A secondary fault zone located 5 m to the east juxtaposes older sediment (>25 ka) against colluvium in apparent normal separation. We exposed a 4 m section consisting of six major peat layers interbedded with fluvial gravel and marsh clay and silt that interfinger eastward with colluvial gravels. A clear, vertical transition from predominantly fine-grained marsh deposits to coarse clastic sediment occurs at a depth of approximately 1 m and is probably caused by historical logging and landuse changes in the watershed. AMS radiocarbon dating of more than 70 samples of peat, macrofossils, and charcoal collected throughout the section indicate that the base of the exposed section is about 2500 yr B.P. We recognize evidence for up to ten earthquakes using outward-splaying, upward fault terminations and fissure fills. The 1906 earthquake ruptures a portion of the upper gravel and a possible late 19th century road fill. Deformation within each of the laterally correlative, upper three peat layers deposited about 300, 700, and 1100 yr B.P. exposed in all the trenches provide age constraints on the timing of four pre-1906 earthquakes. Earlier events were exposed in the one deep excavation and are confined between the section dated to approximately 1200 to 2500 yr B.P. An offset channel traced to the west side of the fault and a buried tree are future targets of study, as they provide excellent piercing points to determine slip of paleoearthquakes. Extension and refinement of the record of earthquakes at this site is anticipated with additional field exploration and continued radiocarbon dating and analyses.

These previous studies failed to fully recognize the interplay of slope failure mechanisms because they lacked detailed field characterization of the cliff. Since construction, the cliff edge has retreated a total of 16 meters to within 6 meters of a building corner. The most recent and one of the largest retreats occurred in 1997-1998. The increased threat of this condition motivated our investigation. Our analysis of historical photographs and topographic maps shows that movement rates are episodic and not evenly distributed over time or location. The most recent failures have occurred in apparent association with large El Nino events: e.g. 2 years following the 1986-1987 El Nino and, again, during the very strong 1997-1998 event. These re-occurring periods of heavy rainfall and attendant higher levels of ground water facilitate slope instability. An innovation of our investigation was to use fixed-ropes to examine the geologic structures exposed in the near-vertical cliff face. Excavations along the base of the cliff previously indicated that the sedimentary rock was cut by a system of NE-trending faults and other associated joints and fractures. Large diameter borings located between the complex and cliff-edge failure zone further exposed a system of open fractures and clay seams trending beneath the buildings. We conclude that slope instability is due to: (1) block slides along gently seaward-dipping clay seams; (2) shallow slumping in the upper 17 meters of soils; (3) topple blocks and rock falls in the conglomerate middle cliffs along numerous near-vertical faults; and (4) wave erosion of the talus slope along the base of the cliff. The interaction of these different mechanisms, enhanced by infiltrating water from natural and other sources, controls the rate of landslides and bluff edge retreat. Previous investigations often concluded with a focus on average retreat rates, which, in light of the episodic retreat process, are very misleading. This investigation shows that the collection and examination of more detailed field data can greatly influence conclusions and lead to a more accurate slope-stability assessment.

AN - 71452748; 11847286 AB - Staphylococcal enterotoxins (SEs) are superantigenic protein toxins responsible for a number of life-threatening diseases. The X-ray structure of a staphylococcal enterotoxin A (SEA) triple-mutant (L48R, D70R, and Y92A) vaccine reveals a cascade of structural rearrangements located in three loop regions essential for binding the alpha subunit of major histocompatibility complex class II (MHC-II) molecules. A comparison of hypothetical model complexes between SEA and the SEA triple mutant with MHC-II HLA-DR1 clearly shows disruption of key ionic and hydrophobic interactions necessary for forming the complex. Extensive dislocation of the disulfide loop in particular interferes with MHC-IIalpha binding. The triple-mutant structure provides new insights into the loss of superantigenicity and toxicity of an engineered superantigen and provides a basis for further design of enterotoxin vaccines.

The two lava samples examined show distinctly different chemical signatures that are considered to represent the dominance of sediment melt (Agrigan) or fluid (Guguan) components derived from the subducting slab and transferred to the mantle wedge, and thus provide an opportunity to examine melt inclusions from both fluid- and sediment melt-dominated arc melting systems. Unhomogenized melt inclusions from both samples examined, as well as other lavas from the same islands, contain unusual subsilicic amphiboles as mineral inclusions within melt inclusions. Textural evidence, as well as the compositions of laboratory-melted inclusions, suggests that these amphiboles may have been present as an early-formed phenocryst phase and trapped alongside melt within inclusions. Major element compositions of homogenized melt inclusions vary substantially, and in part are attributable to "accumulative" amphibole contributions. Inclusions that appear to contain little or no amphibole component, however, typically have higher MgO and FeO (sub T) and lower CaO and Al (sub 2) O (sub 3) contents than their host and associated lavas. Melt inclusions also display a large range of incompatible element abundances. Although the relative abundances of incompatible elements are generally consistent with the composition of lavas from Agrigan and Guguan, melt inclusion compositions are also substantially more variable than lava compositions from these islands. Melt inclusions from the two samples analyzed have Ba/La and [La/Sm] (sub N) ratios (chemical indicators of addition of slab-fluid and slab-derived melt components, respectively) similar in magnitude to the entire field of Mariana lava compositions. In general inclusions from Agrigan have higher La/Nb, Th/Nb, U/Nb, [La/Sm] (sub N) , [La/Yb] (sub N) , K (sub 2) O/TiO (sub 2) and lower Cl/K (sub 2) O, Ba/La, Ba/Nb, Ba/Th and Ce/Ce* than Guguan melt inclusions. These signatures are consistent with addition of slab-sediment-derived melt and slab-derived fluid to the melting systems beneath Agrigan and Guguan, respectively. We suggest that the large variations apparent in melt inclusion compositions largely represent differences in the flux of slab-derived components to the mantle wedge beneath individual arc melting systems, although small-scale variations in the depletion of the mantle wedge could also play a role. Our data also indicates that the composition of the slab-derived sediment melt supplied to the mantle wedge beneath Agrigan may be compositionally heterogeneous, although a larger data set is required to examine this in further detail. The presence of melt inclusions of highly variable composition in relatively evolved olivine phenocrysts (Fo (sub 64) -Fo (sub 83) ) show that, regardless of the ultimate cause of the incompatible element variations in melt inclusions, discrete melts of distinctly different compositions persist without substantial intermixing within the magmatic plumbing systems beneath Agrigan and Guguan (and presumably other arc volcanoes) during long intervals of magmatic differentiation. This suggests a model of small batches of magma migrating and differentiating beneath arc volcanoes, with mixing occurring only at a very late and probably shallow stage.

The NMR data suggest that changes in surface speciation are driven by solution pH and to a lesser extent alkali concentrations, and not by reaction time or saturation state. The (super 29) Si cross-polarization NMR results show that the concentration of silanol surface complexes decreases with increasing pH, suggesting that silanol sites polymerize to form siloxane bonds with increasing pH. Increases in silica surface charge are offset by sorption of alkali cations to ionized sites with increasing pH. It is the increase in these ionized sites that appears to control silica polymorph dissolution rates as a function of pH. The (super 23) Na and (super 133) Cs NMR results show that the alkali cations form outersphere surface complexes and that the concentration of these complexes increases with increasing pH. Changes in surface chemistry cannot explain decreases in dissolution rates as amorphous silica saturation is approached. We find no evidence for repolymerization of the silanol surface complexes to siloxane complexes at longer reaction times and constant pH.

Recent advances in laboratory measurement techniques have provided high quality compressional velocity (Vp) and shear velocity (Vs) data for soils at low pressures that can be used to improve interpretation of field data. This paper presents a new approach for constraining interpretation of seismic velocity data in terms of subsurface soil distribution, intended for application to environmental and engineering problems. An inversion code has been developed to obtain the soil distribution in the shallow sub-surface from Vp and Vs data. The code minimizes the misfit between the observed (simulated field) Vp, Vs pairs of data in the region of interest and velocities for known soil composition as determined by second-order curve fits to laboratory velocity-pressure data for soils. The paper shows how laboratory data can be used to infer lithology from simulated field data for two near-surface examples. The laboratory data used for this purpose are ultrasonic velocity measurements from artificial soils made by combining various amounts of sand, clay, and peat moss. The availability of laboratory data for Vp and Vs at low pressures allows quantification of the improvement in resolution that may be possible if Vp and Vs seismic data are used together to image the shallow subsurface. It is shown that using the two datasets together provides better estimates of subsurface structure than either Vp or Vs alone can provide.

The fundamental goal of rock physics is to find precise physical relationships between different rock properties. In particular, relationships between measurable properties, such as wave velocity, and properties of great interest that are not easily measured, such as permeability, are the "holy grail" of rock physics. Our basic assumption is that the pore scale structure (geometry) of the mineral grains, the mineral composition of the grains, and the pore fluid together completely determine physical rock properties. We compute rock properties from digital rocks using a variety of numerical methods, each appropriate for the property to be computed. In all cases, we attempt to compute rock properties by simulating a laboratory measurement. In principle, as the digital representation of the rock geometry and composition becomes finer, the computed properties become more exact. We currently compute porosity, permeability, electrical conductivity, elastic moduli, and seismic wave velocities from digital rocks. Comparisons between computed rock properties and laboratory measurements for bead packs are presented to demonstrate the usefulness of our approach. Current research is focused on optimizing computational kernels to allow finer grid resolution to be used in our digital rock models and development of algorithms for rock diagenesis. The latter is particularly important because it will form the foundation of our attempt to find definitive rock physics relationships with rock composition and structure as the only free parameters.

Such integrity must span both the relatively brief prograde (active-injection) and indefinite retrograde (post-injection) phases of the sequestration process. Concomitant lateral containment of CO2 migration within the aquifer itself represents another significant component of successful isolation. Reactive transport modeling of CO2 sequestration in shale-capped saline aquifers has identified four distinct mineral-trapping mechanisms that continuously enhance cap-rock integrity and self-seal the intra-aquifer immiscible plume throughout the prograde and retrograde regimes. In each case, carbonate precipitation results from kinetically controlled mass transfer that involves ambient formation minerals, the aqueous wetting phase, and immiscible CO2, whose post-injection residual saturation catalyzes retrograde mineral trapping. Specifically, siderite-magnesite precipitates within the clay-rich shale cap rock while dawsonite precipitates throughout the intra-aquifer plume, whose lateral and upper margins are delimited by simultaneous, genetically distinct precipitation of siderite-magnesite-calcite rind. Although local porosity and permeability are reduced--and therefore CO2 migration is retarded--by each of these four mechanisms, such reduction is most extreme in the cap rock because of its relatively large Fe and Mg concentrations, which derive from a preponderance of clay minerals. During a 20-year (10-year prograde, 10-year retrograde) simulation, mineral trapping from these four processes sequesters less than one percent by mass of injected CO2. However, this seemingly negligible contribution has enormous strategic significance: by continuously enhancing cap rock integrity, it ensures isolation of the voluminous immiscible plume and solubility-trapped CO2.

Until recently, reliable measurements of such properties were hampered by technical problems, such as the difficulty of making pure materials. These difficulties have been largely overcome using methods developed over the last 5 years, including a simple method for making >99% pure sI and sII hydrates. Preservation of such material by cooling to 77 K has made possible accurate measurements of thermal diffusivity and the ductile rheology of compacted sI methane hydrate possible. By integrating hydraulic compaction and sensors into the synthesis vessel, reliable measurements of wavespeeds (Vp and Vs) and thermal conductivity (k) have been made on compacted sI and sII hydrates. Standout results include discovering hydrocarbon hydrate properties are generally very different from those of ice. For example, sI methane hydrate is 20 to 50 times stronger than ice and has a thermal conductivity less than 20% that of ice. While progress has been made in measuring physical properties of pure hydrates, these data have not been tested for internal consistency or sensitivity to hydrate composition. Although these data are now being used with rock-physics theories to evaluate the effects of hydrates on sediment properties, these theories are largely untested. Finally, the problem of retrieving naturally occurring hydrates without partial decomposition has not been solved, and this shortcoming has prevented comparison of naturally occurring hydrates with synthetic hydrates.

Only five wells have been drilled within the Upper Jurassic to Miocene sediments on the continental slope off Scotian Basin. None of these wells have discovered any hydrocarbons. At least eight source rock facies are identified or projected (from the DSDP/ODP wells) in sediments from the Middle Jurassic (Callovian) to Tertiary Banquereau formations. Organic-rich amorphous organic facies that have anoxic signatures are likely present in intervals within local "microbasins". These "microbasins" have developed, primarily, in association with major growth fault or salt diapirism. Maturity data indicates a decrease in heat flow from west to east and wide variability within various "microbasins". Numerical modeling documents at least three pulses of hydrocarbon expulsion and migration from the source rock units. Hydrocarbon migration follows the path of major growth faults and fractures caused by salt movement. The presence of pockmarks on the Scotian Slope indicates probable gas seepage, which supports the modeling.

We used a quadrupole ICP mass spectrometer at sea to acquire continuous trace element data during separate surveys of the Baja California coastal margin, and the San Diego Bay and coastal environment. There is evidence for extreme Ba depletion in surface waters off the Baja coast, which is the result of biological productivity and marine barite precipitation. The synoptic data are used to elucidate the biochemical mechanism of barium removal; to constrain the spatial and temporal boundaries over which the phenomenon occurs; and to quantify surface flux to sediments. Further systems application led to mapping of the distribution of a suite of biologically active trace metals (Mn, Ni, Zn, Cu, and Cd) in San Diego Bay, and the Bay signature was tracked in tidal plumes into the coastal ocean. The continuous data provided chemical gradients within the Bay, with which we estimate the contaminant metal flux that is discharged from the Bay into the coastal ocean during tidal pumping.

The ejected fluid comes from a fluid well that is externally compressed by a PZT bimorph that compresses a thin silicon membrane wall on the driven fluid well. This device design is amenable to arrays of dispensers although only one channel was fluid tested. It produced uniform droplets 150 mu m in diameter.

While many individual ETS components have been shown experimentally to induce lung tumors, ETS itself was only recently shown to induce lung tumors in a series of studies in which strain A/J mice were exposed to well-defined ETS atmospheres. Data from these studies indicate that ETS exposure clearly can increase combined malignant and benign lung tumors in multiple experiments involving male and female A/J mice, and thus provide convincing evidence that ETS is a positive mouse carcinogen. Tumorigenic potencies estimated from these A/J mouse bioassay data predict a corresponding range of increased human risk (0.2-0.5%) that overlaps that implied by case-control studies showing increased lung cancer risks in lifelong nonsmokers married to smokers. In A/J mice exposed to a significantly tumorigenic ETS concentration, lung tumors were found to be significantly smaller than those in corresponding control mice, and mice so exposed for 9 months had significantly fewer tumors/animal than mice exposed for 5 months followed by 4 months in filtered ETS-free air. These findings support hypotheses that ETS does not promote growth of spontaneous neoplastic foci in A/J mice, and that ETS-induced lung-tumor risk in A/J mice occurs predominantly by genotoxic effects that can be suppressed by reduced cell proliferation associated with chronic, high-level ETS exposure. The results obtained add to evidence that A/J mouse lung tumors induced by ETS provide a relevant biological model of ETS-induced human lung tumors.

The X-ray structure of a staphylococcal enterotoxin A (SEA) triple-mutant (L48R, D70R, and Y92A) vaccine reveals a cascade of structural rearrangements located in three loop regions essential for binding the alpha subunit of major histocompatibility complex class II (MHC-II) molecules. A comparison of hypothetical model complexes between SEA and the SEA triple mutant with MHC-II HLA-DR1 clearly shows disruption of key ionic and hydrophobic interactions necessary for forming the complex. Extensive dislocation of the disulfide loop in particular interferes with MHC-II alpha binding. The triple-mutant structure provides new insights into the loss of superantigenicity and toxicity of an engineered superantigen and provides a basis for further design of enterotoxin vaccines.

Methods and Results: Particulate matter was collected on a device designed to filter 1.4 x 10 super(6) litres of air in a 24 h period on a 1-lm pore size polyester membrane. Methods were optimized for extraction of genomic DNA from the air filter concentrate. Preparation times of 90 s with 0.5-0.05 mm diameter zirconia/silica beads yielded the highest concentration genomic DNA that was able to support PCR. A 24-h air sample was taken in Salt Lake City, Utah and the microbial composition was determined by the amplification and sequence analysis of 16S ribosomal DNA fragments. Conclusions: Sequence analysis revealed a large diversity in the type of microbial species present including clones matching the sequence of Clostridium botulinum . The primary components of the aerosol sample included many different spore-forming bacteria as well as more fragile members of the Proteobacteria division. Significance and Impact of the Study: The high-volume air collection and genomic DNA recovery system allows for the rapid detection of both cultivable as well as culture-resistant organisms in the environment.

AN - 71488243; 11866537 AB - Abasic sites and non-conventional 3'-ends, e.g. 3'-oxidized fragments (including 3'-phosphate groups) and 3'-mismatched nucleotides, arise at significant frequency in the genome due to spontaneous decay, oxidation or replication errors. To avert the potentially mutagenic or cytotoxic effects of these chromosome modifications/intermediates, organisms are equipped with apurinic/apyrimidinic (AP) endonucleases and 3'-nucleases that initiate repair. Ape1, which shares homology with Escherichia coli exonuclease III (ExoIII), is the major abasic endonuclease in mammals and an important, yet selective, contributor to 3'-end processing. Mammals also possess a second protein (Ape2) with sequence homology to ExoIII, but this protein exhibits comparatively weak AP site-specific and 3'-nuclease activities. Prompted by homology modeling studies, we found that substitutions in the hydrophobic pocket of Ape1 (comprised of F266, W280 and L282) reduce abasic incision potency about fourfold to 450,000-fold, while introduction of an ExoIII-like pocket into Ape2 enhances its AP endonuclease function. We demonstrate that mutations at F266 and W280 of Ape1 increase 3' to 5' DNA exonuclease activity. These results, coupled with prior comparative sequence analysis, indicate that this active-site hydrophobic pocket influences the substrate specificity of a diverse set of sequence-related proteins possessing the conserved four-layered alpha/beta-fold. Lastly, we report that wild-type Ape1 excises 3'-mismatched nucleotides at a rate up to 374-fold higher than correctly base-paired nucleotides, depending greatly on the structure and sequence of the DNA substrate, suggesting a novel, selective role for the human protein in 3'-mismatch repair.

AN - 71434950; 11827711 AB - This study was conducted to evaluate the ability of mutation in the hypoxanthine-phosphoribosyltransferase gene (HPRT) to detect radiation-induced mutation in lymphocytes of Russian Chernobyl Clean-up workers, particularly as a function of time after exposure. It is part of a multi-endpoint study comparing HPRT mutation with chromosome translocation and glycophorin A mutation [Radiat. Res. 148 (1997) 463], and extends an earlier report on HPRT [Mutat. Res. 431 (1999) 233] by including data from all 9 years of our study (versus the first 6 years) and analysis of deletion size. Blood samples were collected from 1991 to 1999. HPRT mutant frequency (MF) as determined by the cloning assay was elevated 16% in Clean-up workers (N=300, the entire group minus one outlier) compared to Russian Controls (N=124) when adjusted for age and smoking status (P=0.028). Since exposures occurred over a short relative to the long sampling period, the year of sampling corresponded roughly to the length of time since exposure (correlation coefficient=0.94). When date of blood sample was considered, Control MF was not time dependent. Clean-up worker MF was estimated to be 47% higher than Control MF in 1991 (P=0.004) and to decline 4.4% per year thereafter (P=0.03). A total of 1123 Control mutants and 2799 Clean-up worker mutants were analyzed for deletion type and size by PCR assay for retention of HPRT exons and flanking markers on the X chromosome. There was little difference between the overall deletion spectra of Clean-up workers and Controls. However, there was a decline in the average size of deletions of Clean-up workers as time after exposure at Chernobyl increased from 6 to 13 years (P< or =0.05). The results illustrate the sensitivity of HPRT somatic mutation as a biomarker for populations with low dose radiation exposure, and the dependence of this sensitivity on time elapsed since radiation exposure.

AN - 71457396; 11842105 AB - Human Exo1 is a member of the RAD2 nuclease family with roles in replication, repair and recombination. Despite sharing significant amino acid sequence homology, the RAD2 proteins exhibit disparate nuclease properties and biological functions. In order to identify elements that dictate substrate selectivity within the RAD2 family, we sought to identify residues key to Exo1 nuclease activity and to characterize the molecular details of the human Exo1-DNA interaction. Site-specific mutagenesis studies demonstrate that amino acids D78, D173 and D225 are critical for Exo1 nuclease function. In addition, we show that the chemical nature of the 5'-terminus has a major impact on Exo1 nuclease efficiency, with a 5'-phosphate group stimulating degradation 10-fold and a 5'-biotin inhibiting degradation 10-fold (relative to a 5'-hydroxyl moiety). An abasic lesion located within a substrate DNA strand impedes Exo1 nucleolytic degradation, and a 5'-terminal abasic residue reduces nuclease efficiency 2-fold. Hydroxyl radical footprinting indicates that Exo1 binds predominantly along the minor groove of flap DNA, downstream of the junction. As will be discussed, our results favor the notion that the single-stranded DNA structure is pinched by the helical arch of the protein and not threaded through this key recognition loop. Furthermore, our studies indicate that significant, presumably biologically relevant, differences exist between the active site dynamics of Exo1 and Fen1.

AN - 71495207; 11873525 AB - The analysis of chromosome translocations by fluorescence in situ hybridization ("whole chromosome painting") is the gold standard endpoint for radiation biological dosimetry. Translocation formation requires mis-repair of two or more DNA double-strand breaks, a critical class of damage that is efficiently induced by ionizing radiation in a dose-responsive manner. Translocations are widely used for radiation exposure assessment because they provide a sensitive detection system for low doses, show good specificity for radiation exposure, persist for decades, and are highly relevant to tumorigenesis. This paper provides a brief evaluation of the use of translocation analyses by chromosome painting for biological dosimetry following chronic or low-dose exposure to ionizing radiation.

From water recharged in 1960 to water recharged in 1990, a 1.2 ppm and 11 ppm increase occurs in delta (super 18) O and delta D, respectively. Historic temperature records from surrounding areas show a 1.3 degrees C increase in mean annual air temperature over the same time period. This temperature change alone is not great enough to explain the observed increase in delta (super 18) O. We suggest that changes in atmospheric circulation patterns, which have been documented in this region, account for the remaining increase in delta (super 18) O. The time scale of these climatic changes, recorded in both the historical and the hydrological records, is extremely short (decadal scale) and suggests that the delta (super 18) O of groundwater can be a useful tool for studying climatic and atmospheric circulation changes over very short time intervals.

The effects on the transmissivity of frequency, angle of incidence, layer thickness, permeability and elastic compliance of the rocks are all considered. Consistent with previous analytical work, it is found that the equilibration of fluid pressure between the fine layers of a sedimentary sequence can produce significant P-wave attenuation at low frequencies. For this attenuation mechanism to act within the surface-seismic band (say, 3-300 Hz), we find that there must be layering present at the scale of centimeters to tens of centimeters. If the layering is restricted to layers of roughly 1 m thickness or greater, then for typical sandstone formations, the attenuation caused by the interlayer flow occurs below the seismic band of interest. Such low-frequency interlayer flow is called Biot slow-wave diffusion in the context of Biot theory and is likely to be the dominant source of low-frequency attenuation in a sedimentary basin, even for relatively tight and stiff reservoir rock; however, the effect is enhanced in more compliant materials. At higher frequencies, the generation of slow-waves at interfaces is also shown to significantly affect the P-wave scattering so long as the layers are sufficiently thin and sufficiently compliant. This effect on the P-wave scattering is shown to increase with increasing angle of incidence. Our work is limited to performing numerical experiments, with care given to making realistic estimates of all the material properties required. No attempt is made here to define an equivalent viscoelastic solid that allows for such slow-wave effects.

Stable isotope and fluid inclusion studies establish a genetic relationship between vein formation and metamorphic-hydrothermal systems of the region. These extraordinary (super 87) Sr/ (super 86) Sr ratios require accumulation of radiogenic (super 87) Sr in a high Rb/Sr system over an extended period prior to incorporation of Sr into the hydrothermal veins. Evaluation of the age and composition of potential sources of highly radiogenic Sr indicates that the ore-bearing veins of the Coeur d'Alene district formed during the Cretaceous from components scavenged from rocks of the Belt Supergroup, the primary host rocks of the district. Proterozoic Pb isotope ratios observed in galena from many Coeur d'Alene veins were established when Pb separated from uranium during deposition or diagenesis of the Belt Supergroup at 1400 to 1500 Ma, possibly as disseminated syngenetic deposits. K-Ar and Rb-Sr apparent ages and delta (super 18) O values of Belt Supergroup rocks decrease from the Coeur d'Alene district toward the Idaho and Kaniksu batholiths, approximately normal to the trends of metamorphic isograds, fold axes, foliation, and the major reverse faults of the district. Isoclinal folding, thrust faulting, high-temperature metamorphism, granitic plutonism, and regional-scale metamorphic-hydrothermal activity is documented in the region between 140 and 45 Ma, representing the only such combination of events in the Coeur d'Alene region subsequent to about 1300 Ma. The Sr and oxygen results and geologic evidence favor formation of the ore-bearing carbonate veins by fluids related to a complex metamorphic-hydrothermal system during the Cretaceous. Pb with Proterozoic isotopic compositions was probably mobilized and incorporated like other metals into the hydrothermal veins during this event. The ore-bearing veins were sheared and displaced during early Tertiary northwest-trending dextral strike-slip faulting along the Osburn fault and related structures of the Lewis and Clark line.

The silica grains in the mesostases of the CV PRCs are typically replaced by hedenbergitic pyroxenes, whereas anorthitic plagioclase is replaced by feldspathoids (nepheline and minor sodalite). Some of the PRCs contain regions that are texturally and mineralogically similar to type I chondrules and consist of forsterite, low-Ca pyroxene and abundant FeNi-metal nodules. Several PRCs are surrounded by igneous rims or form independent compound objects. Twelve PRCs contain relic calcium-aluminum-rich inclusions (CAIs) composed of anorthite, spinel, high-Ca pyroxene, + or -forsterite, and + or -Al-rich low-Ca pyroxene. Anorthite of these CAIs is generally more heavily replaced by feldspathoids than anorthitic plagioclase of the host chondrules. This suggests that either the alteration predated formation of the PRCs or that anorthite of the relic CAIs was more susceptible to the alteration than anorthitic plagioclase of the host chondrules. These observations and the presence of igneous rims around PRCs and independent compound PRCs suggest that the CV PRCs may have had a complex, multistage formation history compared to a more simple formation history of the CR PRCs. Relatively high abundances of moderately-volatile elements such as Cr, Mn and Si in the PRCs suggests that these chondrules could not have been produced by volatilization of ferromagnesian chondrule precursors or by melting of refractory materials only. We infer instead that PRCs in carbonaceous chondrites formed by melting of the reduced chondrule precursors (magnesian olivine and pyroxene, FeNi-metal) mixed with refractory materials (relic CAIs) composed of anorthite, spinel, high-Ca pyroxene, and forsterite. The mineralogical, chemical and textural similarities of the PRCs in several carbonaceous chondrite groups (CV, CO, CH, CR) and common presence of relic CAIs in these chondrules suggest that PRCs may have formed in the region(s) intermediate between the regions where CAIs and ferromagnesian chondrules originated.

The records are not stationary; during the past 2740 yr, drought durations ranged from 20 to 100 yr and intervals between droughts ranged from 80 to 230 yr. Comparison of tree-ring-based reconstructions of climate change for the past 1200 yr from the Sierra Nevada and the El Malpais region of northwest New Mexico indicates that severe droughts associated with Anasazi withdrawal from Chaco Canyon at 820 cal yr BP (calendar years before present) and final abandonment of Chaco Canyon, Mesa Verde, and the Kayenta area at 650 cal yr BP may have impacted much of the western United States. During the middle Holocene (informally defined in this paper as extending from 8000 to 3000 cal yr BP), magnetic susceptibility values of sediments deposited in Pyramid Lake's deep basin were much larger than late-Holocene (3000-0 cal yr BP) values, indicating the presence of a shallow lake. In addition, the mean delta (super 18) O value of CaCO (sub 3) precipitated between 6500 and 3430 cal yr BP was 1.6 per mil less than the mean value of CaCO (sub 3) precipitated after 2740 cal yr BP. Numerical calculations indicate that the shift in the delta (super 18) O baseline probably resulted from a transition to a wetter (>30%) and cooler (3-5 degrees C) climate. The existence of a relatively dry and warm middle-Holocene climate in the Truckee River-Pyramid Lake system is generally consistent with archeological, sedimentological, chemical, physical, and biological records from various sites within the Great Basin of the western United States. Two high-resolution Holocene-climate records are now available from the Pyramid and Owens lake basins which suggest that the Holocene was characterized by five climatic intervals. TIC and delta (super 18) O records from Owens Lake indicate that the first interval in the early Holocene (11,600-10,000 cal yr BP) was characterized by a drying trend that was interrupted by a brief (200 yr) wet oscillation centered at 10,300 cal yr BP. This was followed by a second early-Holocene interval (10,000-8000 cal yr BP) during which relatively wet conditions prevailed. During the early part of the middle Holocene (8000-6500 cal yr BP), high-amplitude oscillations in TIC in Owens Lake and delta (super 18) O in Pyramid Lake indicate the presence of shallow lakes in both basins. During the latter part of the middle Holocene (6500-3800 cal yr BP), drought conditions dominated, Owens Lake desiccated, and Lake Tahoe ceased spilling to the Truckee River, causing Pyramid Lake to decline. At the beginning of the late Holocene ( approximately 3000 cal yr BP), Lake Tahoe rose to its sill level and Pyramid Lake increased in volume.

They do not deal with dose from emissions of tritiated hydrogen gas (HT) and conversion of HT to HTO in the environment, nor do they address the dose from ingesting tritium incorporated into organic compounds. A simple model (NEWTRIT) is proposed that accounts for all pathways to dose from atmospheric releases of HT and HTO. The model is formulated in terms of the tritium-to-hydrogen ratio in each environmental compartment. With each transfer, a small reduction in the ratio is introduced to reflect the dilution that occurs in nature. Conversion of HT to HTO in the environment is modeled using the latest experimental data. Concentrations of organically bound tritium are calculated in foodstuffs based on amounts of hydrogen in proteins, fats, and carbohydrates. Concentrations in foodstuffs and doses calculated by NEWTRIT are consistent with the predictions of existing regulatory models. In addition, the HTO component of NEWTRIT is tested using public bioassay data and the HT component is tested using results from a model intercomparison study for a hypothetical HT release. Although tritium doses probably have not been underestimated by regulatory models that account only for HTO (due to the high degree of conservatism built into these models), the explicit treatment of HT and organically bound tritium proposed here will make the dose assessments more comprehensive, defensible, and scientifically acceptable. Because NEWTRIT includes all pathways to dose and predicts conservative doses, it is a suitable model to replace the tritium models currently used for compliance.

This technique was demonstrated with Escherichia coli lac repressor, LacI. The consensus promoter binding sequence for LacI and a scrambled version of the same DNA sequence were prepared on two affinity chip surfaces. Total E. coli protein lysate was applied to the two surfaces. A 38.2 kDa protein, as detected by SELDI-MS, was captured on the chip surface containing the binding sequence for LacI but not on the surface containing the scrambled sequence. The protein was identified following one-step, small-scale affinity capture and peptide mapping. Subsequent database searches identified the 38.2 kDa protein as the lac repressor of E. coli. We discuss application of DNA chip affinity capture to characterize transcription factors and to screen for differences in cellular regulatory networks. [copy ]2002 Elsevier Science (USA).

Using sequences derived from the glycerol-negative biovar orientalis strain CO92, a set of 27 locus-specific primers was designed to amplify fragments between the end of IS100 and its neighboring gene. Geographically diverse members of the orientalis biovar formed a homogeneous group with identical genotype with the exception of strains isolated in Indochina. In contrast, strains belonging to the glycerol-positive biovar antiqua showed a variety of fingerprinting profiles. Moreover, strains of the biovar medievalis (also glycerol positive) clustered together with the antiqua isolates originated from Southeast Asia, suggesting their close phylogenetic relationships. Interestingly, a Manchurian biovar antiqua strain Nicholisk 51 displayed a genotyping pattern typical of biovar orientalis isolates. Analysis of the glycerol pathway in Y. pestis suggested that a 93-bp deletion within the glpD gene encoding aerobic glycerol-3-phosphate dehydrogenase might account for the glycerol-negative phenotype of the orientalis biovar. The glpD gene of strain Nicholisk 51 did not possess this deletion, although it contained two nucleotide substitutions characteristic of the glpD version found exclusively in biovar orientalis strains. To account for this close relationship between biovar orientalis strains and the antiqua Nicholisk 51 isolate, we postulate that the latter represents a variant of this biovar with restored ability to ferment glycerol. The fact that such a genetic lesion might be repaired as part of the natural evolutionary process suggests the existence of genetic exchange between different Yersinia strains in nature. The relevance of this observation on the emergence of epidemic Y. pestis strains is discussed.

AN - 71409567; 11812172 AB - BACKGROUNDPredicting and tailoring optimal cancer treatments presents a major challenge.METHODSA computational model (kinetically tailored treatment, or KITT model) is developed to predict drug combinations, doses, and schedules likely to be effective in reducing tumor size and prolonging patient life. Treatment strategies may be tailored to individuals based on tumor cell kinetics. The model incorporates intra-tumor heterogeneity and evolution of drug resistance, apoptotic rates, and cell division rates. Tumor growth may follow an exponential or a Gompertzian trajectory. Drug pharmacodynamic and pharmacokinetic models are used. Toxicity is modeled in several ways.RESULTSA key prediction of KITT is that including cytostatic drugs like tamoxifen and herceptin during treatment with cytotoxic drugs substantially increases the probability of cure and prolongs patient life. Results also suggest that altering drug scheduling may be more effective but not more toxic than dose escalation. CAF chemotherapy (cyclophosphamide, adriamycin, and 5-fluorouracil) is predicted to be more effective than CMF (cyclophosphamide, methotrexate, and 5-fluorouracil). KITT also suggests that tumors with a high proliferative index (PI) may respond better to drug combinations incorporating two cell-cycle phase-specific drugs than do tumors with a low PI. Tumors with a low PI, in contrast, are predicted to respond better to regimens involving two cell-cycle phase-non-specific drugs than do tumors with a high PI. These predictions are borne out by clinical trial results published in the literature, which are discussed. Simulated predictions of the model match well with results from a clinical trial by Silvestrini et al. (2000. Int. J. Cancer 87, 405). The results of simulating the growth of 26896 tumors are used to construct a decision tree for prognosis to identify the key tumor and treatment variables.CONCLUSIONAdditional tests of the model are needed in which physicians collect information on apoptotic and proliferative indices, cell-cycle times, and drug resistance from biopsies of each individual's tumor. Computational models may become important tools to help optimize and tailor cancer treatments.

To determine whether disruption of this gene affects chromosome segregation in male germ cells, we evaluated the frequencies of disomic and diploid sperm in CENP-B heterozygous and homozygous null mice using the mouse epididymal sperm aneuploidy (m-ESA) assay, a multicolor FISH method with probes for chromosomes X, Y and 8. The specificity and sensitivity of the m-ESA assay was demonstrated using Robertsonian (2.8) translocation heterozygotes as positive controls for sperm aneuploidy. Our results show that the frequencies of disomic and diploid sperm did not differ significantly between CENP-B heterozygous and homozygous null mice ( P greater than or equal to 0.5 ) or from 129/Swiss isogenic mice ( P greater than or equal to 0.5 ) and B6C3F1 mice ( P greater than or equal to 0.2 ).

AN - 72707812; 12449317 AB - In vitro assays demonstrated that toluene-grown cells of Geobacter metallireducens catalyzed the addition of toluene to fumarate to form benzylsuccinate under anaerobic conditions. The specific in vitro rate of benzylsuccinate formation was ca. 45% of the specific in vivo rate of toluene consumption. In addition, bssA and bssB, which code for the alpha and beta subunits of benzylsuccinate synthase (BSS), respectively, were found to have sequences in G. metallireducens similar to the only sequences heretofore available (for three denitrifying strains). This is the first report of the presence of BSS in a ferric iron-reducing bacterium; BSS activity has previously been reported in denitrifying, sulfate-reducing, and anoxygenic phototrophic toluene degraders, as well as in a highly enriched methanogenic, toluene-degrading culture.

AN - 71574302; 11921178 AB - Heterocyclic amines produced from overcooked foods are extremely mutagenic in numerous in vitro and in vivo test systems. One of these mutagens, 2-amino-1-methyl-6-phenylimidazo[4,5-b]pyridine (PhIP), induces breast tumors in rats and has been implicated in dietary epidemiology studies as raising the risk of breast cancer in humans. Efforts in our laboratory and others have centered on defining the exposure to PhIP and other dietary mutagens derived from cooked food. We accomplish this by analyzing the foods with a series of solid-phase extractions and HPLC. We have developed an LC/MS/MS method to analyze the four major human PhIP metabolites (sulfates and glucuronides) following a single meal containing 27 microg of cooking-produced PhIP in 200 g of grilled meat. Although the intake of PhIP was similar for each of eight women, the total amount excreted in the urine and the metabolite profiles differed among the subjects. It appears that adsorption (digestion) from the meat matrix, other foods in the diet, and genetic differences in metabolism may contribute to the variation. The four major metabolites that can be routinely assayed in the urine are N(2)-OH-PhIP-N(2)-glucuronide, PhIP-N(2)-glucuronide, 4'-PhIP-glucuronide, and N(2)-OH-PhIP-N3-glucuronide. This work is suited to investigate individual exposure and risk, especially for breast cancer, from these potent dietary mutagens.

Strata dated as 18-9 Ma record a significant counterclockwise rotation (-11 degrees + or - 5 degrees ), whereas unconformably overlying younger strata (7-6 Ma) are not rotated. The age of rotation thus is between 9 and 7 Ma, a period that coincides with the widespread Quechua 2 deformation phase. Moreover, eight independent studies on 107-9 Ma rocks from Peru between 9 degrees S and 15 degrees S reveal similar and significant rotations (-15 degrees + or -6 degrees ). This suggests that the region rotated during a 2 m.y. period of deformation ca. 8 Ma, when the Andes underwent rapid uplift and important deformation commenced in the Subandean zone.

The difference in matrix mass absorption at K and K fluorescence energies of a particular element can be exploited to yield information on the average depth-position of the element or account for heterogeneity effects. Using this technique, the heterogeneous distribution of Cu in a simple layered sample could be resolved to a 2X2X10 (x, y, z, where z is the depth coordinate) micrometer scale; a depth-resolution limit was determined for the first transition metal series and several other elements in calcite and iron oxide matrices. For complex heterogeneous systems, determination of average element depth may be computationally limited but the influence of heterogeneity on fluorescence data may still be assessed. We used this method to compare solid-state diffusion with sample heterogeneity across the Ni-serpentine/calcite boundary of a rock from Panoche Creek, California. We previously reported that Ni fluorescence data may indicate solid state diffusion; in fact, sample heterogeneity in the depth dimension can also explain the Ni fluorescence data. Depth heterogeneity in samples can lead to misinterpretation of synchrotron X-ray microprobe results unless care is taken to account for the influence of heterogeneity on fluorescence data.

The model is larger, includes larger offsets, lies in deeper water, includes surface streamer, multicomponent OBC and VSP acquisition, and contains more hydrocarbons than its predecessor. In addition to AVO analysis, we believe these data will be suitable for calibrating emerging technologies including converted wave tomography and vector seismic processing.

The models will be made available to the research community, along with the synthetic data that are being calculated from them. These shared models have been proposed or contributed by participants in a collaborative industry, national laboratory, and university research project. The purpose of the modeling is to provide synthetic data to better understand elastic wave propagation and the effects of structural and stratigraphic complexities. The 2-D models are easier to design and change and synthetic calculations can be run relatively quickly in them. It will be possible to alter their layer properties and calculate time-lapse data sets from them. Field data will be available to accompany many of the 2-D models. 3-D models are more realistic, but more difficult to design and change. They also require considerably more computing resources to calculate synthetic data from them. A new 3-D model is being designed, and will be used for computing synthetic elastic data.

The results show an average hemispheric offset over the 900 yr of measurement of 40+ or -13 yr. This value is not constant but varies with a periodicity of about 130 yr. The Northern Hemisphere measurements confirm the validity of the Pearson et al. (1986) calibration dataset.

Similarly, the prehistoric tree-ring record produced over 3 decades by the Aegean Dendrochronology Project is shown to provide robust, well-replicated data, contrary to a recent unfounded assertion. (super 14) C and dendrochronology provide an accurate and precise chronometric framework for the Mediterranean region.

Using the data presented in Hogg et al., we show that during the period AD 950-1850 the (super 14) C offset between the hemispheres is not constant, but varies periodically ( approximately 130 yr periodicity) with amplitudes varying between 1 and 10 per mil (i.e. 8-80 yr), with a consequent effect on the (super 14) C calibration of material from the Southern Hemisphere. A large increase in the offset occurs between AD 1245 and 1355. In this paper, we present a Southern Hemisphere high-precision calibration data set (SHCa102) that comprises measurements from New Zealand, Chile, and South Africa. This data, and a new value of 41+ or -14 yr for correction of the IntCal98 data for the period outside the range given here, is proposed for use in calibrating Southern Hemisphere (super 14) C dates.

Species variability in benthic foraminiferal and diatom assemblages provides additional palaeoceanographic evidence. AMS radiocarbon dating of the sediments and oxygen isotope stratigraphy serve as the basis for the age models of the cores for the last 20 (super 14) C kyr and for correlation between environmental variations in the Okhotsk Sea, and regional and global climate changes. Benthic foraminiferal assemblages in the two cores (depth 1590 and 1175 m) varied with time, so that we could recognise seven zones with different species composition. Changes in the benthic foraminiferal assemblages parallel major environmental and productivity variations. During the last glaciation, fluxes of organic matter to the sea floor showed strong seasonal variations, indicated by the presence of abundant A. weddellensis and infaunal Uvigerina spp. Benthic foraminiferal assemblages changed with warming at 12.5-11 and 10-8 (super 14) C kyr BP, when productivity blooms and high organic fluxes were coeval with global meltwater pulses 1A and 1B. Younger Dryas cooling caused a decline in productivity (11-10 kyr BP) affecting the benthic faunal community. Subsequent warming triggered intensive diatom production, opal accumulation and a strong oxygen deficiency, causing significant changes in benthic fauna assemblages from 5.26-4.4 kyr BP to present time.

We present and discuss applications of two inherently interface-sensitive techniques that are amenable to application in hydrothermal experimentation: optical second harmonic generation (SHG) and hydrothermal atomic force microscopy (HAFM). Results of experimental SHG from a corundum-water interface are presented, along with a model relating SHG signal in part to the structure of water in the electric double layer. Although the SHG signal is closely related to surface potential, direct extraction of surface potential over a wide range of pH and ionic strength will depend upon better understanding of water structure near oxide-water interfaces. We present applications of HAFM to dissolution and growth of barite, and in particular show that the velocity and spacing of kink sites along [010] and [120] steps can be extracted from the HAFM imagery using a simple step model. The model enables us to conclude that although steps may appear straight in AFM images, the atomic scale roughness can be large, giving rise to kinks at a large percentage of step sites. Both techniques are promising ways to extend our ability to probe and better understand the nature of mineral-water interface chemistry.

Within the last decade two new techniques have promised to remedy this situation. These techniques, optically stimulated luminescence and cosmogenic nuclide surface exposure dating, enable the age of many glacial features to be determined and have allowed us to study the extent and timing of Himalayan glaciation in the late Quaternary. New data show that the local Last Glacial Maximum (LGM) occurred during the early part of the last glacial cycle, in most areas during marine isotope stage 3 (MIS-3). MIS-3 was a time of increased insolation, when the South Asian summer monsoon strengthened and penetrated further north into the Himalaya. The concomitant increased precipitation, occurring as snow at high altitudes, produced positive glacier mass balances, thereby allowing glaciers to advance. On the other hand, during the global LGM, approximately 18-24 ka, Himalayan glaciation was very restricted in extent, generally extending <10 km from contemporary ice margins. Lower insolation at this time produced a weaker monsoon cycle, which in turn resulted in lower snowfall and snow accumulation at high altitudes.

Experiments were performed at confining pressures up to 100 bars and temperatures to 170 degrees C. Measurements presented are an important step toward using field electrical methods to quantitatively search for fractures, infer saturation, and track fluid migration in geothermal reservoirs. Fractured samples show a larger resistivity change at the onset of boiling than intact samples. Monitoring the resistivity of fractured samples as they equilibrate to imposed pressure and temperature conditions provides indication of fluid migration into and out of the matrix.

The tool was developed for deployment in high temperature geothermal wells under a joint program funded by the California Energy Commission, Electromagnetic Instruments (EMI) and the U.S. Department of Energy. The project was performed by EMI and Lawrence Livermore Laboratory (LLNL). Geo-BILT operates at frequencies from 2 to 42 kHz and features a series of three-component magnetic sensors offset at 2 and 5 meters from a three-component magnetic source. The combined package makes it possible to do 3D resistivity imaging, deep into the formation, from a single well. The manufacture and testing of the tool was completed in spring of 2001, and the initial deployment of Geo-BILT occurred in May 2001 at the Lost Hills oil field in southern California at leases operated by Chevron USA. This site was chosen for the initial field test because of the favorable geological conditions and the availability of a number of wells suitable for tool deployment. The second deployment occurred in April 2002 at the Dixie Valley geothermal field, operated by Caithness Power LLC, in central Nevada. This constituted the first test in a high temperature environment. The Chevron Lost Hills site features a fiberglass-cased observation well in the vicinity of a water injector. The injected water, which is used for pressure maintenance and for secondary sweep of the heavy oil formation, has a much lower resistivity than the oil bearing formation. This injection creates a 3D resistivity structure, which is visible from the nearby observation wellbore. Therefore, it is an excellent site for testing the 3D capability of the tool in a low risk environment. The Dixie Valley site offered an environment where the tool could locate near-well fractures associated with steam development. The Lost Hills field measurements yielded a data set suitable for 3D imaging. The Geo-BILT data corresponded to existing conventional logging data and showed clear indications, in several depth intervals, of near-well 3D structure. Subsequent 3D inversion of these data produced a model consistent with non-planar water flow in specific layers. The Dixie Valley measurements identified structures associated with dike intrusions and water inflow at particular depths. Preliminary analysis suggests these structures are steeply dipping, which is consistent with the geology.

Coupled radiocarbon and U-series dates allow (super 14) C to be used as a tracer of ocean circulation rate in the same manner as it is used in the modern ocean. Diagnetic alteration of coral skeletons on the seafloor requires a thorough cleaning of contaminating phases of carbon. In addition, 10% of the coral must be chemically leached prior to dissolution to remove adsorbed modern CO (sub 2) . A survey of modern samples from the full Delta (super 14) C gradient in the deep ocean demonstrates that the coralline CaCO (sub 3) records the radiocarbon value of the dissolved inorganic carbon.

The Salinas Valley has a relatively deep, confined "400-foot" aquifer, overlain by a "180-foot" aquifer and a shallower perched aquifer, all made up of alluvial sand, gravel and clay deposits. Groundwater from the aquifers have different (super 14) C ages: fossil ( (super 14) C = 21.3 percent modern carbon (pmc) for the 400-foot aquifer and modern ( (super 14) C = 72.2-98.2 pmc) for the 180-foot aquifer. Fresh groundwater in all aquifers is recharged naturally and artificially through the Salinas River. The two modes of recharge can be distinguished chemically. We identified several different saline components with distinguishable chemical and isotopic fingerprints. (1) Saltwater intrusion in the northern basin has C1 concentrations up to 1700 mg/L, a Na/Cl ratio less than seawater, a marine Br/Cl ratio, a Ca/Cl ratio greater than seawater, delta (super 11) B between +17 and +38 ppm and (super 87) Sr/ (super 86) Sr between 0.7088 and 0.7096. Excess dissolved Ca, relative to the expected concentration for simple dilution of seawater, correlates with (super 87) Sr/ (super 86) Sr ratios, suggesting base exchange reaction with clay materials. (2) Agriculture return flow is high in NO (sub 3) and SO (sub 4) , with a (super 87) Sr/ (super 86) Sr = 0.7082, delta (super 11) B = 19 ppm and delta (super 13) C between -23 and -17 ppm. The (super 3) H- (super 3) He ages (5-17 years) and (super 14) C data suggest vertical infiltration rates of irrigation water of 3-10 m/yr. (3) Nonmarine saline water in the southern part of the valley has high total dissolved solids up to 3800 mg/L, high SO (sub 4) , Na/Cl ratio >1, delta (super 11) B between +24 and +30 ppm, and (super 87) Sr/ (super 86) Sr = 0.70852. This groundwater may have acquired its geochemical signature from leaching of sedimentary rocks associated with the Coast Range marine deposits of Mesozoic to early Cenozoic age. The combination of different geochemical and isotopic fingerprints enables us to delineate the impact of salt sources in different areas of the valley and to reconstruct the origin of the SO (sub 4) -enriched NO (sub 3) -depleted saline plume that is located west of the city of Salinas. We suggest that the latter is derived from a mixture of different natural saline waters rather than from anthropogenic contamination.

AN - 18575209; 5295257 AB - delta super(18)O records from the GISP2 and GRIP ice cores are widely used as benchmark paleoclimate chronologies, but there are significant differences between the two time scales. The present study shows that offsets between the two chronologies over the past 14,500 yr do not accumulate gradually, but appear over two short intervals of 100-200 yr. An initial offset of 80 yr occurs close to 3300-3400 yr B.P., and another 100 yr of slip appears at the start of the Younger Dryas. Since these discrepancies are localized, resolving them may be far easier than if large sections of both cores required reexamination.

The National Toxicology Program (NTP) was established in 1978 to coordinate research and testing of potential human carcinogens and to publish the Report on Carcinogens, which lists human carcinogens. The results for over 500 chemicals tested in the NTP 2-year bioassays have been published in Technical Reports and include data for chemical, agent, or complex mixture exposures. The bioassays have identified 42 chemicals that induce tumors in the rodent mammary gland. The physical and chemical characteristics of the carcinogens vary, but epoxides (including chemicals metabolized to epoxides) and nitro-containing compounds are well represented. The 9th Report on Carcinogens, issued in 2000, lists 21 of the 42 chemicals as human carcinogens including benzene, ethylene oxide, 1,3-butadiene, isoprene, chloroprene, C.I. basic red 9, and C.I. acid red 114. Ethylene oxide was associated with increased breast cancer risk in an epidemiologic study, whereas other listed chemicals, for which human data are available, display different target organ specificity. Bioassays other than those conducted by the NTP also provide information about rodent mammary gland carcinogens. Several carcinogen exposures are associated with breast tumor induction in both humans and rodents including radiation, diethylstilbestrol, and estrogens. These studies demonstrate that route, timing and frequency of exposure, and genetic factors contribute to the overall susceptibility to breast cancer development. More information is needed on the effects of chemicals to which humans are exposed and the manner by which they influence breast cancer risks.

It can be inferred, on the basis of these observations and interpretations, that a climate change record is preserved in these vadose zone waters. In arid regions where thick (>100 m) vadose zones persist, it has been concluded that this record may extend back more than 100 000 yr. Consideration of the mechanisms that control reactive transport led to the conclusion that such climate-driven effects will also be evident as chemical reactions involving dissolution and/or precipitation of mineral phases along the flow pathway. As a result, there should also be variations in the concentrations of nonconservative chemical species that correspond to changes in the concentrations of the conservative tracers. Simulations of this reactive transport, in a regime typical of the arid U.S. Southwest, demonstrate that these changes can modify pore water chemistry by factors of up to 200%, but the changes take place slowly, requiring thousands of years to achieve steady-state conditions. This suggests that a very rich archive of climate change history is preserved in this type of setting. However, extracting that history is currently hampered by limitations in data and models (e.g., effective mineral reactive surface areas, fluid flow pathways, and quantified models of wetted fracture surface in unsaturated, fractured systems). This challenge may be overcome if coordinated efforts are undertaken that exploit the power of detailed studies of isotope systematics, microscale rock characterization, and high performance computing.

We describe the variation of this conservative isotope tracer with salinity and sediment load. REE data are used to differentiate marine and terrigenous source terrains for suspended material and dissolved fractions. We estimate that about 1-4 x 10 super(10) Bq of super(137)Cs migrates annually on suspended material through the North Bay. In addition, super(137)Cs concentrations were measured in surface waters off Baja California.

AN - 72301022; 11722940 AB - The potential for aerobic methyl tert-butyl ether (MTBE) degradation was investigated with microcosms containing aquifer sediment and groundwater from four MTBE-contaminated sites characterized by oxygen-limited in situ conditions. MTBE depletion was observed for sediments from two sites (e.g., 4.5 mg/liter degraded in 15 days after a 4-day lag period), whereas no consumption of MTBE was observed for sediments from the other sites after 75 days. For sediments in which MTBE was consumed, 43 to 54% of added [U-(14)C]MTBE was mineralized to (14)CO(2). Molecular phylogenetic analyses of these sediments indicated the enrichment of species closely related to a known MTBE-degrading bacterium, strain PM1. At only one site, the presence of water-soluble gasoline components significantly inhibited MTBE degradation and led to a more pronounced accumulation of the metabolite tert-butyl alcohol. Overall, these results suggest that the effects of oxygen and water-soluble gasoline components on in situ MTBE degradation will vary from site to site and that phylogenetic analysis may be a promising predictor of MTBE biodegradation potential.

The Black Mango fault displays evidence of two large surface rupture earthquakes during the past 650 years, subsequent to 1294 A.D. and 1423 A.D., and possibly another rupture at about 260 A.D. Displacement during the last two earthquakes was at minimum 4.6 meters and 2.4 to 4.0 meters, respectively, and possibly larger for the 260 A.D. event. Abandoned terraces of the adjacent Markanda River record uplift due to slip on the underlying HFT of 4.8+ or -0.9 millimeters per year or greater since the mid-Holocene. The uplift rate is equivalent to rates of fault slip and crustal shortening of 9.6 (sub -3.5) (super +7.0) millimeters per year and 8.4 (sub -3.6) (super +7.3) millimeters per year, respectively, when it is assumed that the HFT dips 30 degrees + or -10 degrees .

Intermediate-frequency (0.02-0.04 Hz) fundamental-mode Rayleigh waves propagating across the basin are severely attenuated, but apparent attenuation is significantly less for both low and high frequencies. We have modeled the response of surface waves in a simplified rendition of the South Caspian Basin model of Mangino and Priestly (1998) using a hybrid normal-mode/2D finite-difference approach. To gain insight into the features of the basin that cause the anomalous surface-wave propagation, we have varied parameters of the basin model and computed synthetic record sections to compare with the observed seismograms. We have varied the Moho depth beneath the basin, the shape of the basin boundaries, the thickness and shear-wave Q of the sediments and mantle, and the water depth. Of these parameters, the intermediate-frequency surface waves are most severely affected by the sediment thickness and shear-wave attenuation. All models fail to satisfy observations for frequencies of 0.05 Hz and above, and this failure is attributed to significant 3D wave propagation effects caused by focusing and scattering of surface waves by basin structures.

Late Cenozoic thrusting has folded and sliced Oligocene-Miocence red beds into an imbricate wedge, capped by warped and uplifted Quaternary terraces that form a 2- to 5-km-wide ledge, north of the steeply faceted range front. Seismic scarps 1.5 to 4.5 m high cut young fans along the outer thrusts. Carbon 14 dating of organic remains collected on strath terraces constrains the chronology of deposition and incision by the streams. Most of the fans and terraces in the southern part of the Subei basin appear to have been emplaced after the last glacial maximum, particularly during the early Holocene optimum (9-5 ka). Measurements of the shapes of the warped terraces constrain minimum and maximum throws on the outer thrusts. The minimum vertical throw of 34 + or - 2 m of a surface dated at 8411 + or - 530 years B.P. at one site provides a minimum vertical uplift rate of 4.1 + or - 0.5 mm/yr. The maximum possible uplift (115 + or - 15 m) of the oldest terrace surface, whose probable age is 15 to 18 ka, places an upper bound on the uplift rate of 7 + or - 2 mm/yr. The thrust geometry at depth and the cumulative shortening (10-20 km) deduced from balancing sections logged across the imbricate thrust wedge are consistent with a shortening rate of about 5 mm/yr and an onset of thrusting at about 4 + or - 2 Ma. Such a shortening rate implies a significant northward decrease in slip rate along the Altyn Tagh Fault. The recent growth of the western Qilian mountain ranges thus appears to be intimately coupled with sinistral motion on the Altyn Tagh Fault and the extrusion of Tibet.

Those exposed to precipitation accumulated several times more of this isotope than those shielded from precipitation. No significant difference in (super 7) Be accumulation was observed between a set which was UV irradiated (in an attempt to kill resident bacteria) and a set which received no UV irradiation. This experiment suggests that 62 + or - 10 percent of the beryllium accumulated on the varnish was supplied by precipitation and 38 + or - 10 percent by some combination of dew, dust, and aerosols. If bacteria are, as has been proposed, responsible for varnish growth, then either our UV irradiation was inadequate to squelch their activity or the (super 7) Be we measured had not yet been built into the varnish.

We estimate site response in the Athens area from recordings of aftershocks of the 7 September 1999, Mw=5.9 Athens earthquake at 22 stations. The highest damage from this earthquake was about 15 km from the epicenter. The sites studied are in and around the highest damage area and at about the same distance from the hypocenter, so that differences in site conditions may be the stronger factor in determining where damage occurred. We describe site response from weak motion recordings in two ways: 1) by an inversion to estimate site specific t* (sub g) , and 2) by calculating site response relative to reference sites by the spectral ratio method. We also assemble site specific information on geology of the recording sites and categorize it. We compare these results to estimated intensity at each site to evaluate whether these factors can provide an indicator of potential damage from local earthquakes. We conclude that the spectral ratio method is the best indicator of potential damage. The four sites that had the highest intensities showed the highest amplifications by the spectral ratio method, and most other sites showed relative amplifications consistent with intensity. t*g is a moderately effective method of identifying relative intensity, but did not identify the highest intensity area. Near-surface site geology showed very poor correlation with potential damage. Spectral ratios and t* (sub g) did not correlate with geology very well, but show significant correlation with each other. Microzonation mapping may be better served by mapping spectral ratios and t* (sub g) rather than surface geology to predict potential hazard.

YBI is a rock outcrop in San Francisco Bay, California, and is often used as a reference site in research and engineering studies. We identified 18 earthquakes in the area for which weak motion was recorded at the bottom and top of a 61-m borehole. Examining this data, we found that: (1) near-surface rock above the downhole site does not have a significant site response of its own; (2) there is a regional effect on seismic energy that severely attenuates frequencies above about 2 Hz. We suspect that this is due to propagation through the highly heterogeneous basement Franciscan formation. (3) Plots of the spectra for most of the recorded earthquakes show evidence for a spectral hole in the downhole recordings between 8 and 11 Hz as compared to the uphole recordings. We attribute this to interference between the up and downgoing waves. The downhole recordings would therefore cause a bias if used as a reference site without consideration of this interference. From these three observations, we conclude that at YBI the surface site provides the best recordings for reference rock sites or input into soils or engineering models. However, the effect of a regional site effect causing near-constant corner frequencies for recordings of M (sub 4.0) earthquakes means that there is no true reference site, flat in spectral amplifications, available in the region. In this paper, we also compare site response and transfer function calculations using an auto-regressive moving average (ARMA) transfer function, and the horizontal-average, cross-spectra, complex signal, and horizontal-to-vertical spectral ratio methods. We found that the complex signal spectral ratio and ARMA transfer function calculations were more stable as both site response calculations and as transfer functions. The horizontal-to-vertical method best revealed the lack of site response at YBI, and the calculation with just background noise gave as good results as that with seismic signal.

AN - 71223519; 11585917 AB - The UV-sensitive V-H1 cell line has a T46I substitution mutation in the Walker A box in both alleles of XPD and lacks DNA helicase activity. We characterized three partial revertants that curiously display intermediate UV cytotoxicity (2- to 2.5-fold) but normal levels of UV-induced hprt mutations. In revertant RH1-26, the efficient removal of pyrimidine (6-4) pyrimidone photoproducts from both strands of hprt suggests that global-genomic nucleotide excision repair is normal, but the pattern of cyclobutane pyrimidine dimer removal suggests that transcription-coupled repair (TCR) is impaired. To explain the intermediate UV survival and lack of RNA synthesis recovery in RH1-26 after 10 J of UV/m(2), we propose a defect in repair-transcription coupling, i.e., the inability of the cells to resume or reinitiate transcription after the first TCR event within a transcript. All three revertants carry an R658H suppressor mutation, in one allele of revertants RH1-26 and RH1-53 and in both alleles of revertant RH1-3. Remarkably, the R658H mutation produces the clinical phenotype of trichothiodystrophy (TTD) in several patients who display intermediate UV sensitivity. The XPD(R658H) TTD protein, like XPD(T46I/R658H), is codominant when overexpressed in V-H1 cells and partially complements their UV sensitivity. Thus, the suppressing R658H substitution must restore helicase activity to the inactive XPD(T46I) protein. Based on current knowledge of helicase structure, the intragenic reversion mutation may partially compensate for the T46I mutation by perturbing the XPD structure in a way that counteracts the effect of this mutation. These findings have implications for understanding the differences between xeroderma pigmentosum and TTD and illustrate the value of suppressor genetics for studying helicase structure-function relationships.

Last updated - 2017-02-22 ER - TY - JOUR T1 - Uranium-series and radiocarbon geochronology of deep-sea corals; implications for Southern Ocean ventilation rates and the oceanic carbon cycle AN - 52157139; 2002-008608 AB - We present new uranium-series and radiocarbon measurements for deep-sea corals from the Southern Ocean. These data are used to reconstruct ventilation ages, both at present and at the end of the last glacial period approximately 16500 years ago. We apply an improved two-component mixing approach to correct uranium-series dates for contaminant thorium and protactinium present in oxide coatings. Calculated seawater radiocarbon values for contemporary samples decrease with depth in the water column and agree with direct seawater radiocarbon measurements for this area. This indicates that deep-sea corals can accurately record seawater radiocarbon distributions. Two of three glacial samples experienced open-system uranium-series systematics, however, a third sample from the Drake Passage yields concordant thorium and protactinium dates as well as seawater values for initial (super 234) U/ (super 238) U. This coral yields a ventilation age that is approximately 20-40% greater than modern values for its location. This increase is consistent with published deep-sea coral and calibrated planktonic-benthic foraminifera radiocarbon data, suggesting that the glacial oceans as a whole may have been substantially less ventilated, presumably due to decreased formation of North Atlantic Deep Water. An overall decrease in oceanic mixing rates could have contributed to lower dissolved carbon in surface ocean water and lower atmospheric pCO (sub 2) during the past glacial period.

Our experiments indicate the evolution of high pH, Na-HCO (sub 3) -CO (sub 3) brines from the Na-HCO (sub 3) -CO (sub 3) water and the evolution of near-neutral pH brines from the Ca-Cl-SO (sub 4) -rich water. The minerals recovered after complete evaporation of the Na-HCO (sub 3) -CO (sub 3) experiments include amorphous silica, aragonite, calcite, halite, niter, thermonatrite and, possibly, gypsum, anhydrite and hectorite. Tachyhydrite and gypsum were observed to form in the experiments with the Ca-Cl-SO (sub 4) -rich water. Limitations in theory and data regarding chemical speciation in highly-concentrated saline solutions, which restrict the usefulness of conventional thermodynamic modeling studies as a tool to assess the evaporative evolution of these waters, will also be discussed.

Cosmogenic (super 10) Be and (super 26) Al exposure dates from tillstones exposed on moraines show the local "LGM" in the Karakax Valley (36 degrees N, 78 degrees E) of the Kunlun Shan occurred at least 65-70 ka. We find no evidence of large marine isotope stage (MIS) 2 glaciers in the Karakax, only Little Ice Age moraines (<1 ka) and active glaciers upvalley of the approximately 70 ka moraines. In contrast to the moraine record, exposure ages on adjoining alluvial fans in the Karakax Valley indicate that they formed during periods of maximum insolation ( approximately 6 ka and approximately 110 ka; Ryerson et al., 1999) rather than maximum glaciation. Moraines that date to MIS 2 or the late glacial in the Aksayqin Basin (35 degrees N, 80 degrees E) on the northwestern Tibetan Plateau are within 1 km of the modern glacier termini. An older, much larger, and more weathered set of moraines lie well outside of the MIS 2 moraines, and appear to be equivalent in age to the early Wisconsinan moraines below the Karakax glaciers. This pattern of large early-Wisconsinan glaciers also occurs in parts of the Tien Shan to the north: cosmogenic dates from several locations (e.g., Die Han Je Le Gou, 43 degrees N, 88 degrees E; Muzart He, 42 degrees N, 81 degrees E) suggest that glaciers there attained maxima during both the early part of the Wisconsinan ( approximately 40-75 ka), but also during MIS 2 (13-28 ka), with the former advance being slightly larger. The pattern suggested by these findings is that, in the hyperarid Kunlun Shan, during the LGM it may simply have been too dry to support large glaciers despite low temperatures. During somewhat warmer, less "glacial" climates (e.g., early Wisconsinan), the local glaciers throughout the region were able to grow because of increased delivery of precipitation. Thus, local glacial maxima were asynchronous with glacial maxima in Europe and western North America, and even in the Himalaya, such that the local LGM occurred early in the 10 (super 5) -year-long glacial cycle phase rather than near its end.

The extent and timing of Laurentide Ice Sheet advances throughout the eastern Canadian Arctic at the LGM have been poorly known largely due to a lack of LGM-age radiocarbon ages for glacial deposits. Recent approaches using lacustrine sediment cores and cosmogenic exposure dating have resulted in significant advances toward understanding Laurentide ice dynamics across southeastern Baffin Island (64 degrees to 67 degrees N, 62 degrees to 68 degrees W; Steig et al., 1998; Bierman et al., 1999; Miller et al., 1999; Marsella et al., 2000; Wolfe et al., 2000; Kaplan et al., 2001). However, unlike in southern Baffin Island where LGM ice left a limited moraine record, the wide coastal forelands of the Clyde region afford the opportunity to study a far more extensive LGM and pre-LGM moraine record. Our (super 10) Be and (super 26) Al ages range from 19 ka for a terminal moraine on the Clyde foreland, to 13 ka and 9 ka for morphostratigraphically younger foreland and fiord-wall lateral moraines and ice-sculpted bedrock islands within Clyde Inlet. This LGM ice limit is intermediate between earlier depictions of the LGM margin at the fiord head (>100 km inland; Miller and Dyke, 1974), and at the continental shelf break in Baffin Bay (80 km beyond; Hughes et al., 1977), and thus resolves a long-standing controversy. (super 10) Be ages from a higher fiord-wall lateral moraine of 32 ka, along with yet undated terminal moraines on the coastal foreland beyond the 19 ka terminal moraine, indicate that the Laurentide was more extensive during pre-LGM times than during the LGM. We infer that there was relatively extensive ice at high latitudes early in the last glacial cycle, during relatively wet times, versus more restricted ice during the arid LGM (e.g., Miller et al., 1977; Miller et al., 1992); ongoing research will further test this hypothesis.

Cosmogenic dating ( (super 10) Be) of four moraines in the Alcacocha Valley (S11 degrees 03', W75 degrees 58', elev. 4300 m, length approximately 14 km) indicates that the most extensive moraines are at least 400,000 years old. In contrast, the LGM is represented mainly by a low, broad terminal moraine located approximately 7 km up valley and 200-250 m higher than the limit of glaciation in the Alcacocha Valley. Within the LGM limit, a recessional moraine dams Laguna Alcacocha. The median (super 10) Be date on the recessional moraine is 17+ or -0.4 ka, which is consistent with an end to the LGM in the region at 21 k cal yr BP based on the sedimentary record in Lake Junin. Down valley of the LGM limit, larger lateral moraines date from approximately 240 to more than 400 (super 10) Be ka. An overall picture emerges of a relatively minor glaciation in the tropical Andes during the LGM, following at least three previous larger glaciations. The pattern is repeated in neighboring valleys. This relationship between the LGM moraines and older moraines is in contrast to the SPECMAP oxygen isotope record, which indicates that global ice buildup during the LGM was similar in magnitude to that of previous glacial periods. These findings invoke a mechanism for maintaining a relatively reduced ice extent in the tropics while allowing significant ice build-up in the high latitudes during the LGM. One possible mechanism might be the disruption of ocean circulation patterns such that the transfer of warmer ocean water from the tropics to the poles was impeded, preventing the tropics from cooling to the same extent as higher latitude regions.

Mapping and (super 10) Be and (super 26) Al cosmogenic dating are used to estimate the timing of the last and penultimate glacial periods, between ca. 25,000 and 15,000, and ca. 175,000 and 125,000 years ago, respectively, in middle latitude Argentina, 46.5 degrees S. Following a major advance during marine isotope stage 6, the next time glaciers reached a maximum extent was between ca. 25,000-20,000 years ago. During marine isotope stage 2 at least six glacial events occurred in less than ca. 10,000 years on the eastern side of the Andes, reflecting millennial scale climate change in Patagonia during this time. If a marine isotope stage 4 event occurred in Patagonia, it was the same extent or smaller than the last glacial maximum. In middle latitude Argentina, the timing of the last glaciation and deglaciation was broadly in phase with that in the Northern Hemisphere. Our findings are consistent with other glacial geologic (and ice core and pollen studies), which, collectively, suggest that glacial advances occurred throughout most of South America on millennial time scales during marine isotope stage 2. This major glaciation occurred despite a high in local insolation at ca. 20,000 years ago; exceptions, where ice did not advance, must reflect a local mechanism such as a severe lack of precipitation for glacial growth.

In the subpolar regions, these events are represented by glacier advances and increases in the concentration of ice-rafted lithic grains. Although large changes in surface ocean currents are implicated, to date there is little evidence for accompanying large changes in deep water circulation. How were these Holocene climate instabilities recorded at lower latitudes? To evaluate the timing and amplitudes of Holocene climate variability in the subtropics, we examined high accumulation rate sediment cores from the eastern subtropical Atlantic and from the Gulf of Aden. A detailed Holocene record of subtropical Atlantic sea-surface temperature (SST) variations was reconstructed from planktonic foraminiferal assemblages at ODP Site 658 off NW Africa. This detailed record reveals a series of large amplitude (2-4 degrees C) cooling events which are synchronous (within 14C chronologies) with the subpolar SST variations. Also, this record indicates that Holocene variability increased from ca. 5 ka BP toward the present, culminating in the largest amplitude variations associated with the Little Ice Age-Medieval Warm Period oscillation. The Red Sea is closed inland basin where strong surface evaporation and winter cooling in the north promotes the formation highly saline (40 psu), warm ( approximately 18-20 degrees C) intermediate waters ( approximately ca. 700-800 m) in the north which are exported southward into the Gulf of Aden. The subsurface export of RSOW is a monitor of regional climate variability and decadal at longer timescales due to the short residence time of these waters in the Red Sea (ca. 25 years). Preliminary benthic oxygen isotope and Mg/Ca data from high sedimentation rate box cores in the Gulf of Aden (western Indian Ocean) document coeval millennial-scale 1-2 degrees C cooling events recorded by RSOW. Collectively, these data argue for large and abrupt variations in subtropical climates which are in phase with high-latitude variability.

Sedimentation rates range from 35 to 100 cm/10 (super 3) yrs. Holocene sediments are finely laminated and composed of alternating layers of carbonate and organic-rich strata. Lithologic variations are expressed in sediment bulk density and magnetic susceptibility that were measured at 0.5 cm increments by a GEOTEK Multi-Sensor Core Logger and by color variations that were determined from digital images captured with a GEOSCAN color line scan camera. The lake was more saline than today throughout the early Holocene (9000 to 7300 cal yr B.P.) as evidenced by the presence of the euryhaline benthic foraminifer Ammonia beccarii. Low, but rising, sea level during this period depressed water levels in the phreatic karst aquifer of northern Yucatan relative to today. Sea level has been at or near present limits for the last 6,000 years and, consequently, lake level variations during the mid-to-late Holocene were controlled primarily by changes in evaporation/precipitation. During this interval, sediment color (red 650-750 nm) variations in the Punta Laguna core are remarkably similar to the %Ti record from the Cariaco Basin (Haug et al., in press), especially in the interval between approximately 3800 and 2500 cal yr B.P. where both records are marked by rapid sub-centennial oscillations. A distinct decrease in variability occurs at 2500 yrs BP in both records and is followed by a 1200-year long period of relative climate stability in which the Maya civilization developed, flourished, and ultimately collapsed in the 9th century A.D. The latter event is marked by a prolonged period of dry climate in both northern Yucatan and Venezuela. The tight coupling of climate variability between these regions is best explained by latitudinal variations in the position of the Atlantic Intertropical Convergence Zone.

Dramatic changes in climate have taken place in as little as 20-30 years during the Holocene, most notably near 7.6 ka when the Santa Barbara Basin experienced rapid cooling then warming to maximum Holocene temperatures. Since Santa Barbara Basin is affected by the Pacific Decadal Oscillation (PDO), periodicities of 20 to 60 years observed in our records are attributed to this phenomenon. Lower frequency variability ( approximately 1,500 year periodicity) appears to be related to changes in global ocean circulation or more likely to associated atmospheric climate effects. Based on six years of sediment trap and concurrent CTD data, we have constructed a two end-member hydrographic model for the Santa Barbara Basin. The "non-El Nino" end-member is equivalent to modern spring upwelling conditions when equatorward California Current flow is strong and productivity is high. This is represented in the sediment trap and in our down-core record by high concentrations of biogenic silica (a proxy for productivity) as well as a small difference between the oxygen isotope values of Globigerina bulloides (a surface dwelling foraminifer) and Neogloboquadrina pachyderma (a thermocline dwelling foraminifer). The "El Nino" end member is equivalent to late summer and fall thermal stratification of the upper water column when the poleward California Undercurrent rises to the surface of the basin and productivity is suppressed. This is represented in the data as low silica concentrations and a large foraminiferal delta (super 18) O difference. Our records suggest that upwelling and productivity are lowest in the Santa Barbara Basin between 5.2 and 3.8 ka, thus we conclude that El Nino was most intense and/or frequent during this mid-Holocene interval. This lies within the period of peak Holocene warmth and indicates that El Nino is strongest when the climate is warmest.

This solution, especially its energy and mass balances, is useful for the validation of numerical shallow water models under stratified, tidally forced conditions. The utility of the analytical solution for validation is demonstrated for a simple finite difference numerical model. The energy, mass, and their balances from the numerical model are shown to converge to the analytical solution with a power law dependence as spatial and temporal resolution are increased. The power law convergence of the numerical results to the analytical solution validates both the finite difference scheme and the open boundary conditions used for the tidal forcing. The open boundary conditions work well because they are consistent with the characteristics of the analytical solution. Copyright 2001 by the American Geophysical Union.

Infection in chickens is asymptomatic; therefore, simple, sensitive, and specific detection methods are crucial for efforts to limit human exposure. Suppression subtractive hybridization was used to isolate DNA restriction fragments present in Salmonella serovar Enteritidis but absent in other bacteria found in poultry environments. Oligonucleotide primers to candidate regions were used in polymerase chain reactions to test 73 non-Enteritidis S. enterica isolates comprising 34 different serovars, including Dublin and Pullorum, two very close relatives of Enteritidis. A primer pair to one Salmonella difference fragment (termed Sdf I) clearly distinguished serovar Enteritidis from all other serovars tested, while two other primer pairs only identified a few non-Enteritidis strains. These primer pairs were also useful for the detection of a diverse collection of clinical and environmental Salmonella serovar Enteritidis isolates. In addition, five bacterial genera commonly found with Salmonella serovar Enteritidis were not detected. By treating total DNA with an exonuclease that degrades sheared chromosomal DNA but not intact circular plasmid DNA, it was shown that Sdf I is located on the chromosome. The Sdf I primers were used to screen a Salmonella serovar Enteritidis genomic library and a unique 4,060-bp region was defined. These results provide a basis for developing a rapid, sensitive, and highly specific detection system for Salmonella serovar Enteritidis and provide sequence information that may be relevant to the unique characteristics of this serovar.

The sampler processed hundreds to thousands of liters of natural waters with variable suspended sediment and salinity loads at flow rates of 10-201/min. Extraction of most radionuclides in the water column was accomplished through the combination of physical filtration down to 0.1 mu m particle size and chemical separation of dissolved species on cellulose-based inorganic sorbent beds without recourse to complex, or hazardous chemistry. Performance and extraction efficiencies for suites of radioisotopes were determined in the laboratory and in the field with river and coastal ocean water samples. Extraction and recovery efficiencies are better than 90% for most fission and activation product radioisotopes. This methodology has broad application to the study of the distribution and fate of radioisotopes in coastal waterways.

Well-dated marine terraces record the timing of sea-level highstands and delimit both uplift and geomorphic rates. Cosmogenic radionuclides provide a new tool for dating previously undatable terraces. Because the five marine terraces north of Santa Cruz, California, are capped by well-developed soils formed in regressive marine sands, both predepositional cosmogenic radionuclide inheritance and bioturbation of the profile must be accounted for. We present a new cosmogenic radionuclide inventory method that uses the depth-integrated cosmogenic radionuclide concentration to determine the terrace age. This method yields terrace ages that correlate well with sea-level highstands of marine oxygen isotope stages 3, 5a, 5c, 5e, and 7.

The approach uses supervised learning and statistical classification algorithms along with advanced signal/image processing algorithms. No model assumption is made, such as hyperbolic moveout. We train a probabilistic neural network for voxel classification using event times, subsurface points, and offsets (ground truth information) picked manually by expert interpreters. The key to success is using effective features that capture the important behavior of the measured signals. We test a variety of features calculated in a local neighborhood about the voxel under analysis. Selection algorithms ensure that we use only the features that maximize class separability. This event-picking algorithm has the potential to reduce significantly the cycle time and cost of 3-D prestack depth migration while making the velocity model inversion more robust.

We performed present-day and preindustrial equilibrium climate simulations. The climate sensitivity is lower by similar to 20% in the equivalent CO sub(2) case compared to the control case in which the individual trace gases were treated explicitly. This is reflected in similar percentage differences in global- and annual-mean surface temperature, precipitation, precipitable water, and sea ice. The temperature changes are also different regionally in the tropical and subtropical troposphere and in the stratosphere. This difference in climate sensitivity originates from differences in the spatial pattern of radiative forcing. The equivalent CO sub(2) forcing pattern differs from the control case forcing pattern for several reasons, but the dependence on temperature of the Planck emission spectrum appears to be fundamentally most important. The primary absorption bands of CH sub(4) and N sub(2)O are found at wavelengths more sensitive to the temperature-related shift of the wavelength of maximum emission than the absorption bands of CO sub(2). This leads to stronger spatial variations in absorption by trace gases than by CO sub(2). We conclude that because of differences in the pattern of radiative forcing, the equilibrium response of global climate to increases in trace gases is larger than the response to an "equivalent" increase in CO sub(2), and the patterns of response are also different.

Geochemical tracer ages were determined with chlorofluorocarbons (CFCs) and tritium/ (super 3) He dating techniques. The spring water ages range from less than 5 years to almost 40 years. Mass balance calculations performed by NETPATH were combined with spring water ages to calculate chemical weathering rates observed throughout the basin, which range from 0.0116 to 0.0018 and from 0.0036 to 0.0006 mmol l (super -1) year (super -1) , for plagioclase and hornblende, respectively. Major cation concentrations, pH, and spring water conductivity were found to correlate positively (R (super 2) = 0.7) with spring water age. This suggests that shallow groundwater, as represented by the springs, is a chemically evolving system.

The disjointed concrete facing blocks are held together through interface friction and concrete keys or mechanical connectors. Because of the disjointed nature of the facing blocks, the design of the segmental wall must consider the available shear resistance between these blocks. Connection capacity must also be considered. Of concern also is the permanent deformation of the segmental wall face following an earthquake. This paper describes a finite-element analysis of a model segmental wall subjected to earthquakelike loading generated by a shake table. The finite-element analysis used the computer program DYNA3D. Results from DYNA3D, using a simple model--Ramberg-Osgood model--to simulate the nonlinear hysteretic behavior of soil, are consistent with observed results from laboratory shake table tests on segmental walls.

The first segmental wall uses concrete facing blocks with pins, and the second wall uses the same concrete blocks but without pins. The analysis provides some insight into the behavior of segmental walls, particularly the load transfer mechanism between the geosynthetic reinforcement and the segmental facing units during earthquake loading.

AN - 50881324; 2001-075296 AB - Antarctic surface waters were warm and ice free between 10,000 and 5000 cal yr B.P., as judged from ice-rafted debris and microfossils in a piston core at 53 degrees S in the South Atlantic. This evidence shows that about 5000 cal yr B.P., sea surface temperatures cooled, sea ice advanced, and the delivery of ice-rafted detritus (IRD) to the subantarctic South Atlantic increased abruptly. They coincide with an early Neoglacial advance of mountain glaciers in South America and New Zealand between 5400 and 4900 cal yr B.P., rapid middle Holocene climate changes inferred from the Taylor Dome Ice Core (Antarctica), cooling and increased IRD in the North Atlantic, and the end of the African humid period.

These integrations were performed using observed sea surface temperatures and from observed initial conditions. The experiments were designed by the Climate Variability and Predictability, Working Group on Seasonal to Interannual Prediction as part of the Seasonal Prediction Model Intercomparison Project. Integrations from the European Union Prediction of Climate Variations on Seasonal to Interannual Timescales experiment are also evaluated. The National Centers for Environmental Prediction-National Center for Atmospheric Research and European Centre for Medium-Range Weather Forecasts reanalyses and observed pentad rainfall form the baseline against which the hindcasts are judged. Pattern correlations and root-mean-square differences indicate errors in the simulation of the time mean low-level flow and the rainfall exceed observational uncertainty. Most models simulate the subseasonal EOFs that are associated with the dominant variations of the 850-hPa flow during the ASM, but not with the fidelity exhibited by the reanalyses as determined using pattern correlations. Pattern correlations indicate that the first EOF, associated with the tropical convergence zone being located over the continental landmass, is best simulated. The higher-order EOFs are less well simulated, and errors in the magnitude and location of their associated precipitation anomalies compromise dynamical seasonal predictability and are related to errors of the mean state. In most instances the models fail to properly project the subseasonal EOFs/principal components onto the interannual variability with the result that hindcasts of the 850-hPa flow and rainfall are poor. In cases where the observed EOFs are known to be related to the boundary forcing, the failure of the models to properly project the EOFs onto the interannual variability indicates that the models are not setting up observed teleconnection patterns.

As anticipated, a strong negative correlation was found between mean annual juvenile rockfish Delta super(14)C and the preceding 3-month average Bakun upwelling index for this region. The sensitivity of this isotopic response by juvenile rockfish to upwelling variations was similar to that previously observed in surface-water inorganic carbon in nearby Half Moon Bay (Robinson 1981). This indicates that the Delta super(14)C of surface-dwelling marine fish can be used as a measure of fish feeding in freshly upwelled super(14)C-depleted water. However, we found no correlation between this parameter and fish somatic condition as measured by deviations in the regressions of individual fish (1) weight on length, (2) otolith size on fish length, or (3) total lipid content on dry weight. This questions the role upwelling plays in affecting juvenile rockfish condition. Also unrelated to fish condition were fish delta super(13)C and delta super(15)N, implying that the condition of juvenile S. jordani is unaffected by variation in the consumption of specific, isotopically discernible food resources.

Garnet-bearing assemblages sampled along the Marysandi River and Darondi Khola in the Annapurna region of central Nepal show striking differences in garnet zoning of Mn, Ca, Mg, and Fe above and below the MCT. Thermobarometry of MCT footwall rocks yields apparent inverted temperature and pressure gradients of approximately 18 degrees C km (super -1) and approximately 0.06 km MPa (super -1) , respectively. Pressure-temperature (P-T) paths calculated for upper Lesser Himalaya samples that preserve prograde compositions show evidence of decompression during heating, whereas garnets from the structurally lower sequences grew during an increase in both pressure and temperature. In situ (i.e., analyzed in thin section) ion microprobe ages of monazites from rocks immediately beneath the Greater Himalayan Crystallines yield ages from 18 to 22 Ma, whereas late Miocene and Pliocene monazite ages characterize rocks within the apparent inverted metamorphic sequence. A Lesser Himalayan sample collected near the garnet isograd along the Marysandi River transect contains 3.3+ or -0.1 Ma monazite ages (P nearly equal 0.72 GPa, T nearly equal 535 degrees C). This remarkably young age suggests that this portion of the MCT shear zone accommodated a minimum of approximately 30 km of slip over the last 3 Ma (i.e., a slip rate of >10 mm yr (super -1) ) and thus could account for nearly half of the convergence across the Himalaya in this period. The distribution of ages and P-T histories reported here are consistent with a thermokinematic model in which the inverted metamorphic sequences underlying the MCT formed by the transposition of right-way-up metamorphic sequences during late Miocene-Pliocene shearing.

The purpose of these experiments was to demonstrate that an ICP-MS can be operated in a harsh environment with no degradation in performance, and that accurate trace element data can be acquired on rapid analytical time scales. Evaluation at sea involved performance testing, characterization and calibration of a real-time sea-water analytical methodology, and continuous sea-water profiling over an extended three day transect from the Gulf of California to San Diego. We show that mass spectrometers can rapidly, precisely and accurately determine trace element concentrations in sea-water, thus allowing high-resolution mapping of large areas of surface sea-water. This analytical capability represents a significant advance toward real-time observation and characterization of water mass chemistry in dynamic coastal environments. While evaluating the ICP-MS off the coast of Baja California, we discovered barium depletion of 65% in surface waters over tens of kilometres.

From 11 August through 25 August 2000, we visited several research institutes in Kazakhstan and consulted with numerous Kazakh researchers from academic disciplines ranging from radioecology to public health and medicine. We focused on reviewing data on the health and environmental impacts resulting from the testing. The health effects caused by the testing at STS have received a fair amount of study, and research using modern techniques such as fluorescence in situ hybridization and nuclear magnetic resonance will likely increase the reliability of dose reconstruction. However, the extent to which the STS is contaminated has not been adequately characterized, and the potential exposure to nomadic peoples and ecological receptors at the uncontrolled test site is not known. Additional research in these areas, and development of administrative controls for the site, appears warranted.

If this inconsistency is due to competing effects of induced cell killing vs. mutations in alpha-radiation exposed bronchial epithelium, then linear extrapolation from miner data may overestimate typical residential radon risks. To investigate the plausibility of this hypothesis, a biologically based "cytodynamic 2-stage" (CD2) cancer-risk model was fit to combined 1950 to 1954 age-specific person-year data on white females of age 40+ y in 2821 U.S. counties ( similar to 90% never-smokers), and on five cohorts of underground miners who never smoked, conditional on a realistic rate of alpha-radiation-induced killing of human lung cells, and on linear-no-threshold dose-response relations for both processes assumed to affect cancer risk (alpha-induced mutations and cell killing). As summarized previously, a good CD2 fit was obtained that involved biologically plausible parameter values and (without further optimization) also predicted inverse dose-rate effects observed in the nonsmoking miners. The present paper reports mathematical details of the CD2 model used, as well as additional modeling results involving the same combined data set. The results obtained are consistent with the hypotheses that low-level radon exposure is nonlinearly related to LCM risk, and that current linear no-threshold extrapolation models overestimate LCM risk associated with relatively low residential radon concentrations (< similar to 200 Bq m super(-3)). Testing this hypothesis would require more extensive individual-level epidemiological data relating residential radon exposures to LCM than are currently available.

AN - 71034087; 11438709 AB - The carcinogenic heterocyclic amine (HA) 2-amino-1-methyl-6-phenylimidazo[4,5-b]pyridine (PhIP) is formed during the cooking of various meats. To enable structure/activity studies aimed at understanding how DNA damaged by a member of the HA class of compounds can ultimately lead to cancer, we have determined the first solution structure of an 11-mer duplex containing the C8-dG adduct formed by reaction with N-acetoxy-PhIP. A slow conformational exchange is observed in which the PhIP ligand either intercalates into the DNA helix by denaturing and displacing the modified base pair (main form) or is located outside the helix in a minimally perturbed B-DNA duplex (minor form). In the main base-displaced intercalation structure, the minor groove is widened, and the major groove is compressed at the lesion site because of the location of the bulky PhIP-N-methyl and phenyl ring in the minor groove; this distortion causes significant bending of the helix. The PhIP phenyl ring interacts with the phosphodiester-sugar ring backbone of the complementary strand and its fast rotation with respect to the intercalated imidazopyridine ring causes substantial distortions at this site, such as unwinding and bulging-out of the strand. The glycosidic torsion angle of the [PhIP]dG residue is syn, and the displaced guanine base is directed toward the 3' end of the modified strand. This study contributes, to our knowledge, the first structural information on the biologically relevant HA class to a growing body of knowledge about how conformational similarities and differences for a variety of types of lesions can influence protein interactions and ultimately biological outcome.

AN - 71067253; 11488562 AB - PEREGRINE is a three-dimensional Monte Carlo dose calculation system written specifically for radiotherapy. This paper describes the implementation and overall dosimetric accuracy of PEREGRINE physics algorithms, beam model, and beam commissioning procedure. Particle-interaction data, tracking geometries, scoring, variance reduction, and statistical analysis are described. The BEAM code system is used to model the treatment-independent accelerator head, resulting in the identification of primary and scattered photon sources and an electron contaminant source. The magnitude of the electron source is increased to improve agreement with measurements in the buildup region in the largest fields. Published measurements provide an estimate of backscatter on monitor chamber response. Commissioning consists of selecting the electron beam energy, determining the scale factor that defines dose per monitor unit, and describing treatment-dependent beam modifiers. We compare calculations with measurements in a water phantom for open fields, wedges, blocks, and a multileaf collimator for 6 and 18 MV Varian Clinac 2100C photon beams. All calculations are reported as dose per monitor unit. Aside from backscatter estimates, no additional, field-specific normalization is included in comparisons with measurements. Maximum discrepancies were less than either 2% of the maximum dose or 1.2 mm in isodose position for all field sizes and beam modifiers.

The author considers a variety of reasons behind India's & Pakistan's decision to develop nuclear weapons programs, eg, internal & external security concerns & the enhancement of international status & leverage. Yet a number of nonproliferation tactics have proven effective: nonproliferation treaties; the high costs of producing & sustaining nuclear arsenals; controls on technological expertise; international inspections & subsequent diplomatic consequences should a clandestine nuclear program be discovered; & coerced (military) containment, such as the US exercised against Libya & Iraq. However, these safeguards may not be adequate to recent & continuing economic & technological developments in mid-sized states that are minimizing costs, delay, & risk factors. The author urges immediate attention to improving the detection & assessment of nuclear proliferation. 1 Table. K.

These long-term sediment yields are, on average, 17 times higher than stream sediment fluxes measured over 10-84 yr, but are consistent with 10 m.y. erosion rates measured by apatite fission tracks. Our results imply that conventional sediment-yield measurements--even those made over decades--can greatly underestimate long-term average rates of sediment delivery and thus overestimate the life spans of engineered reservoirs. Our observations also suggest that sediment delivery from mountainous terrain is extremely episodic, sporadically subjecting mountain stream ecosystems to extensive disturbance.

Garnets in the structurally lowest rocks grew with increasing T and P (loading), whereas garnets 1-3 km upsection grew with increasing T, but decreasing P (exhumation). Monazite grains in structurally lower rocks yield ion- microprobe Th-Pb ages of 8-9 Ma. Structurally higher monazite grains range from 10 to 22 Ma. The P-T-t paths confirm previous interpretations that footwall metamorphism in part resulted from thrust reactivation ca. 8 Ma, but also reflect thermal relaxation following older (20 Ma or older) thrust movement.

Studies to date have focused on very large volcanic edifices (e.g., Hawaiian Islands, Marquesas), but less attention has been paid to smaller islands, which are more common. Ascension Island, a 4-km high volcanic edifice with a basal diameter of 60 km, is located in the equatorial Atlantic (8 degrees S), 90 km west of the Mid-Atlantic Ridge on 7 Ma oceanic lithosphere. We present results of a wide-angle seismic profile crossing the island revealing a crustal thickness of 12-13 km, an overthickened layer 3 (7 km thick) and little evidence of lithospheric flexure. Together these results suggest Ascension Island may be older than previously assumed and may have begun forming at an on-axis position around 6-7 Ma. This hypothesis is further supported by the presence of a young 1.4-km high edifice directly adjacent to the Mid-Atlantic Ridge with a volume about 1/7 that of Ascension Island, possibly representing the earliest stages of seamount formation. Excess magmatism appears to be related to the tectonic setting at the ridge-fracture zone intersection.

Based on the (super 36) Cl- (super 36) Ar, (super 10) Be- (super 21) Ne and (super 26) Al- (super 21) Ne pairs in the metal fraction, we derive an average cosmic-ray exposure age of 66+ or -7 Ma. Chinguetti is now the third out of 20 mesosiderites with an exposure age between 60 and 70 Ma. This may be the first hint of a major impact on the parent body of the mesosiderites, which show ages ranging from 10 to 300 Ma (Terribilini et al., 2000). From the (super 14) C- (super 10) Be pair we derive a terrestrial age of 18+ or -1 ka, which seems too recent to be consistent with the original description of the main mass having a heavily wind-eroded base, overhung by the upper part of the meteorite. Finally, from the radionuclide concentrations in combination with Monte-Carlo based calculations, we conclude that our sample of Chinguetti was irradiated at a depth of approximately 15 cm in an object not larger than 80 cm in radius. This is the most compelling evidence against the reports that the Chinguetti mesosiderite is a small fragment of a mass 100 m long and 40 m high.

This issue is investigated using climate model simulations. By imposing observed coverage changes on simulated surface temperatures, estimates are obtained of twentieth-century temperature change for both full global coverage and for actual historical coverage. In 10 out of 16 simulations including human climate perturbations, the temperature change from the globally complete model output is significantly larger than that derived from the historically masked model output. The remaining six simulations show no significant difference between complete and masked model output. Thus, these results do not support the hypothesis that the increase in the earth's surface temperature has been overestimated because of incomplete observational data. Rather, if the simulations analyzed are realistic, the true temperature increase over the last century is slightly larger than that estimated from available observations. Eight simulations of natural internal climate variability, which omit human climate perturbations, were analyzed. In none of these simulations does the temperature change during 100 yr-whether obtained from globally complete or masked model output-come close to the observed twentieth-century temperature increase.

These solvers take advantage of the fast, robust convergence of globalized Newton methods as well as the parallel scalability of multigrid preconditioners. We compare two multigrid methods. The methods differ primarily in their handling of discontinuous and anisotropic permeability fields, with one method invoking a simple pointwise smoothing technique and the other a more expensive plane smoother. Computational results are presented to show the effectiveness of the entire nonlinear solution procedure, to demonstrate the effect of discontinuities and anisotropies, and to explore parallel efficiencies.

Recent studies have shown that in humans, UDP-glucuronosyltransferase (UGT)-mediated glucuronidation plays a critical role in the detoxification of food-borne carcinogenic heterocyclic amines. 2-Amino-1-methyl-6-phenylimidazo[4,5-b]pyridine (PhIP), the most abundant carcinogenic heterocyclic amine found in well-cooked meats, has been shown to be extensively glucuronidated in humans. To determine which UGT isozymes are involved in the biotransformation of PhIP and the cytochrome P4501A2-mediated reactive intermediate N-hydroxy-PhIP, microsomes expressing human UGT1A1, -1A4, -1A6 or -1A9 were incubated with PhIP and N-hydroxy-PhIP and the reaction products analyzed by HPLC and ESI-MS. Incubations containing N-hydroxy-PhIP and UGT1A1 expressing microsomes, with an apparent K sub(m) of 4.58 mu M and a V sub(max) of 4.18 pmol/min/mg protein, had the highest capacity to convert N-hydroxy-PhIP to N-hydroxy-PhIP-N super(2)-glucuronide. Microsomes expressing UGT1A9 produced N-hydroxy-PhIP-N3-glucuronide at the highest rate with an apparent K sub(m) and V sub(max) of 3.73 mu M and 4.07 pmol/min/mg, respectively. A third previously undefined glucuronide accounted for 31% of the total glucuronides formed from the UGT1A4 expressing microsomes. No glucuronide conjugates were detected from microsomes expressing UGT1A6. Incubations containing PhIP as substrate formed direct PhIP-glucuronides in microsomes expressing UGT1A1, UGT1A4 and UGT1A9 but at levels averaging 53-fold lower than when N-hydroxy-PhIP was used as the substrate. Knowing the glucuronidation capacity of the specific UGT isozymes involved in PhIP and N-hydroxy-PhIP glucuronidation should help in determining the individual susceptibility to the potential cancer risk from exposure to PhIP.

The first is represented by J13 well water, a dilute Na-HCO sub(3)-CO sub(3) water similar to saturated horizons in volcanic tuffs across the western United States. The second is represented by Ca-Cl-SO sub(4)-rich pore water that has a higher dissolved ion content, from the unsaturated zone above the repository horizon. Data include anion and cation analysis and qualitative mineral identification for a series of open system experiments, with and without crushed tuff present, conducted at sub-boiling temperatures (75-85 degree C). This work is motivated by a need to characterize the chemistry of concentrated aqueous films that might form on engineered components at the potential high-level, nuclear-waste repository at Yucca Mountain, Nevada and lead to electrochemical corrosion. The experiments indicate the evolution of high pH, Na-HCO sub(3)-CO sub(3) brines from J13-like waters and the evolution of near-neutral pH brines from the pore water compositions. The minerals recovered after complete evaporation of the J13 water alone experiments include amorphous silica, aragonite, calcite, halite, niter, thermonatrite and, possibly, gypsum, anhydrite and hectorite. Tachyhydrite and gypsum were observed to form in equivalent experiments with pore waters from the unsaturated zone.

ER - TY - JOUR T1 - The human interferon- and estrogen-regulated ISG20/HEM45 gene product degrades single-stranded RNA and DNA in vitro. AN - 70917667; 11401564 AB - The human ISG20/HEM45 gene was identified independently on the basis of its increased level of expression in response to either interferon or estrogen hormone. Notably, the encoded protein is homologous with members of the 3' to 5' exonuclease superfamily that includes RNases T and D, and the proofreading domain of Escherichia coli DNA polymerase I. We provide here direct biochemical evidence that Isg20 acts as a 3' to 5' exonuclease in vitro. This protein displays a pH optimum of approximately 7.0, prefers Mn2+ as a metal cofactor, and degrades RNA at a rate that is approximately 35-fold higher than its rate for single-stranded DNA. Along with RNase L, Isg20 is the second known RNase regulated by interferon. Previous data showed that Isg20 is located in promyelocytic leukemia (PML) nuclear bodies, known sites of hormone-dependent RNA polymerase II transcription and oncogenic DNA viral transcription and replication. The combined data suggest a potential role for Isg20 in degrading viral RNAs as part of the interferon-regulated antiviral response and/or cellular mRNAs as a regulatory component of interferon and estrogen signaling.

AN - 85346209; pmid-11425102 AB - We show that the time reversal operator for a planar time reversal mirror (TRM) can have up to four distinct eigenvalues with a small spherical acoustic scatterer. Each eigenstate represents a resonance between the TRM and an induced scattering moment of the sphere. Their amplitude distributions on the TRM are orthogonal superpositions of the radiation patterns from a monopole and up to three orthogonal dipoles. The induced monopole moment is associated with the compressibility contrast between the sphere and the medium, while the dipole moments are associated with density contrast. The number of eigenstates is related to the number of orthogonal orientations of each induced multipole. For hard spheres (glass, metals) the contribution of the monopole moment to the eigenvalues is much greater than that of the dipole moments, leading to a single dominant eigenvalue. The other eigenvalues are much smaller, making it unlikely multiple eigenvalues could have been observed in previous experiments using hard materials. However, for soft materials such as wood, plastic, or air bubbles the eigenvalues are comparable in magnitude and should be observable. The presence of multiple eigenstates breaks the one-to-one correspondence between eigenstates and distinguishable scatterers discussed previously by Prada and Fink [Wave Motion 20, 151-163 (1994)]. However, eigenfunctions from separate scatterers would have different phases for their eigenfunctions, potentially restoring the ability to distinguish separate scatterers. Since relative magnitudes of the eigenvalues for a single scatterer are governed by the ratio of the compressibility contrast to the density contrast, measurement of the eigenvalue spectrum would provide information on the composition of the scatterer.

Here we show that long-term chemical weathering rates can be measured by combining physical erosion rates, inferred from cosmogenic nuclides, with dissolution losses, inferred from the rock-to-soil enrichment of insoluble elements. We used this method to measure chemical weathering rates across 22 mountainous granitic catchments that span a wide range of erosion rates and climates. Chemical weathering rates correlate strongly with physical erosion rates but only weakly with climate, implying that, by regulating erosion rates, tectonic uplift may significantly accelerate chemical weathering rates in granitic landscapes.

Scientific viability of this approach hinges on the relative effectiveness of CO2 migration and sequestration processes in the subsurface; its successful implementation relies on our ability to predict sensitivity of this migration/sequestration balance to key physical and chemical characteristics of potential target reservoirs. Quantification of this sensitivity reveals geochemical, hydrologic, and structural constraints on maximizing sequestration performance that can be used to identify geologic formations most likely to provide optimal storage capacity and isolation security. We are integrating kinetically-controlled reactive-transport and multiphase-flow simulators (GIMRT, NUFT), supporting geochemical software and thermodynamic/kinetic databases (SUPCRT92, GEMBOCHS), and recent equation-of-state and viscosity formulations for CO2 (Span and Wagner, 1996; Fenghour et al., 1998) to develop a unique modeling capability for identifying optimal target formations in this manner. Initial benchmark modeling has focused on simulating CO2 injection at the unique Sleipner facility, where properties of the target aquifer and its bounding cap rock are well constrained and location of the migrating CO2 plume after three years of injection has been established. Preliminary results suggest that local permeability structure of the target formation controls CO2 movement by all migration processes (immiscible displacement, gravity segregation, and viscous fingering) and the potential effectiveness of all sequestration processes (structural, solubility, and mineral trapping). For typical sandstone aquifers, at least 90% of the injected CO2 migrates as an immiscible plume; hence, potential structural trapping represents the dominant sequestration mechanism. Intra-aquifer shales retard vertical and promote horizontal CO2 migration, thus expanding the volumetric extent of CO2-aquifer interaction, and thereby increasing the potential effectiveness of solubility and mineral trapping. Relative impermeability of clay-rich inter-bedded and cap-rock shales may be enhanced by carbonate precipitation at the CO2-shale interface, thus improving cap-rock integrity-the most important constraint on long-term isolation performance.

The simulators serve as numerical laboratories within which a series of experiments can be designed, carried out, and analyzed to quantify sensitivity of the overall injection/sequestration process to specific compositional, hydrologic, structural, thermodynamic, and kinetic parameters associated with the injection fluid and subsurface environment. The simulations begin with simple batch-type reactions that simulate titration of an equilibrated reservoir rock/water system with a gas phase that starts off pure CO (sub 2) and has SO (sub 2) incrementally added to it. We then construct a series of simulations in which the batch-type reactions are perturbed by periodically flushing out the aqueous phase and permitting the evolved reservoir rock system to re-equilibrate with the "fresh" aqueous phase. This is a "rock-centered", pseudo-flow-through simulation. Both of these initial types of simulations are pure thermodynamic calculations: no reaction kinetics are invoked. We then construct a series of simulations that are equivalent to the first batch-type (closed system) reactions, but this time including dissolution kinetics for all of the mineral phases present in the reservoir rock and assuming a composition and modal abundance appropriate for a feldspathic sandstone containing clay and carbonate with and without an Fe-bearing phase. Several approaches to dealing with setting fO2 are investigated. In these simulations reaction progress is allowed to proceed for a time period of 30 years, appropriate for a real CO (sub 2) sequestration process.

The present day dissolved concentrations and distribution of the stable and radioactive isotopes of Be and Al in ocean waters have revealed their short residence times and appreciable effects of exchange fluxes at the coastal and ocean-sediment interfaces. It follows that concentrations of these particle-active elements must have varied in the past with temporal changes in climate, biological productivity and aeolian flux of continental detritus to the oceans. We therefore investigated the feasibility of extending the measurements of Be and Al isotope concentrations in marine systems to the 10 (super 3) -10 (super 6) y BP time scale. We report here the discovery of significant amounts of intrinsic Be and Al in marine foraminiferal calcite and coral aragonite, and of Al in opal (radiolarians) and aragonite (coral), which makes it possible to determine (super 10) Be/Be and (super 26) Al/Al in oceans in the past. We also report measured (super 10) Be/ (super 9) Be in foraminiferal calcite in Pacific Ocean cores, which reveal that the concentrations and ratios of the stable and cosmogenic isotopes of Be and Al have varied significantly in the past 30 ky. The implications of these results are discussed.

The creep of polycrystalline ice I with average grain size of 0.25 mm and larger is consistent with previously published dislocation creep laws, which are now extended to strain rates as low as 2 X 10 (super -8) s (super -) 1. When ice I is reduced to very fine and uniform grain size by rapid pressure release from the ice II stability field, the rheology changes dramatically. At 200 and 220 K the rheology matches the grain-size-sensitive rheology measured by Goldsby and Kohlstedt [1997, this issue] at 1 atm. This finding dispels concerns that the Goldsby and Kohlstedt results were influenced by mechanisms such as microfracturing and cavitation, processes not expected to operate at elevated pressures in planetary interiors. At 233 K and above, grain growth causes the fine-grained ice to become more creep resistant. Scanning electron microscopy investigation of some of these deformed samples shows that grains have markedly coarsened and the strain hardening can be modeled by normal grain growth and the Goldsby and Kohlstedt rheology. Several samples also displayed very heterogeneous grain sizes and high aspect ratio grain shapes. Grain-size-sensitive creep and dislocation creep coincidentally contribute roughly equal amounts of strain rate at conditions of stress, temperature, and grain size that are typical of terrestrial and planetary settings, so modeling ice dynamics in these settings must include both mechanisms.

Although individual small mountainous rivers export trivial amounts of sediment and carbon to the ocean, as a group these rivers may export a major fraction (as much as 50%) of the total global river sediment flux [Milliman and Syvitski, 1992], making their geochemistry relevant the study of the ocean's carbon cycle. In addition, many small rivers export sediment in a few high flux events, causing massive, sporadic discharge of carbon onto coastal shelves, discharge conditions very different from those of large rivers. This class of rivers is an end-member of the river-ocean carbon exchange system,. opposite the Earth's largest river, the Amazon. The carbon mass and isotopic properties of the Santa Clara River are significantly different from previously studied large rivers. During the 1997-1998 winter, all Santa Clara carbon pools were old, with flux-weighted average Delta (super l4) C values of-428 + or - 76 per mil for particulate organic carbon, -73+ or - 31 per mil for dissolved organic carbon, and-644+ or -58 per mil for black carbon. The age of exported carbon is primarily due to the deep erosion of old soils and not to inclusion of fossil fuel carbon. Additionally, the delta (super 13) C signatures of exported carbon pools were high relative to terrestrial carbon, bearing a signature quite similar to marine carbon (average particulate organic carbon (POC) delta (super 13) C = -22.2 + or - 0.8 per mil). The Santa Clara's estuary is small and drains onto the narrow eastern Pacific coastal margin, exporting this old soil organic matter directly into the ocean. If the Santa Clara export patterns are representative of this class of rivers, they may be a significant source of refractory terrestrial carbon to the ocean.

To maximize the potential S & E attractiveness of the inertial fusion energy (IFE), analyses must be performed early in the designs so that lessons can be learned and intelligent decisions made. In this work we have introduced for the first time heat transfer and thermal-hydraulics calculations as part of a state-of-the-art set of codes and libraries in order to establish an updated methodology for IFE safety analysis. We have focused our efforts primarily on two IFE power plant conceptual designs: HYLIFE-II and SOMBRERO. To some degree, these designs represent the extremes in IFE power plant designs. Also, a preliminary safety assessment has been performed for a generic target fabrication facility producing various types of targets and using various production techniques. Although this study cannot address all issues and hazards posed by an IFE power plant, it advances our understanding of radiological safety of such facilities. This will enable better comparisons between IFE designs and competing technologies from the safety point of view.

AN - 18102791; 5202364 AB - The objective of this assessment is to determine what level of cleanup will be required to meet regulatory and stakeholder needs in the case of a chemical and/or biological incident at a civilian facility. A literature review for selected, potential chemical and biological warfare agents shows that dose information is often lacking or controversial. Environmental regulatory limits or other industrial health guidelines that could be used to help establish cleanup concentration levels for such agents are generally unavailable or not applicable for a public setting. Although dose information, cleanup criteria, and decontamination protocols all present challenges to effective planning, several decontamination approaches are available. Such approaches should be combined with risk-informed decision making to establish reasonable cleanup goals for protecting health, property, and resources. Key issues during a risk assessment are to determine exactly what constitutes a safety hazard and whether decontamination is necessary or not for a particular scenario. An important conclusion is that cleanup criteria are site dependent and stakeholder specific. The results of a modeling exercise for two outdoor scenarios are presented to reinforce this conclusion. Public perception of risk to health, public acceptance of recommendations based on scientific criteria, political support, time constraints, and economic concerns must all be addressed in the context of a specific scenario to yield effective and acceptable decontamination.

Participatory ergonomic intervention techniques have proven to be beneficial in the prevention of musculoskeletal disorders. The participatory approach to ergonomics has also been found to be a useful application within industrialized (developed) countries and industrially developing countries (IDCs). Grassroots ergonomics principles utilize expertise within a workforce that focuses on participatory ergonomics interpretations of quantitative and qualitative risk and exposure assessment information that in turn results in a peer-developed ergonomics training. Regardless of the intricacy of the exposure assessment tools, workers should fully assist in gathering and analyzing data, then in identifying and implementing solutions. A coordinated and multidisciplinary application of this approach within IDCs would succeed in the creation and sharing of job-specific ergonomics training information for high physical exposure professions, such as agriculture, fishing, forestry, mining, and small-scale enterprises, to initiate ergonomics programs regionally.

AN - 71057344; 11477514 AB - Heterocyclic amines (HAs) formed in fried, broiled or grilled meats are potent mutagens that increase rates of colon, mammary, prostate and other cancers in bioassay rodents. Studies of how human dietary HA exposures may affect cancer risks have so far relied on fairly crudely defined HA-exposure categories. Recently, an integrated, quantitative approach to HA-exposure assessment (HAEA) was developed to estimate compound-specific intakes for particular individuals based on corresponding HA-concentration estimates that reflect their meat-type, intake-rate, cooking-method and meat-doneness preferences. This method was applied in the present study to U.S. national Continuing Survey of Food Intakes by Individuals (CSFII) data on meats consumed and cooking methods used by >25,000 people, after adjusting for underreported energy intake and conditional on meat-doneness preferences estimated from additional survey data. The U.S. population average lifetime time-weighted average of total HAs consumed was estimated to be approximately 9 ng/kg/day, with 2-amino-1-methyl-6-phenylimidazo[4,5-b]pyridine (PhIP) estimated to comprise about two thirds of this intake. Pan-fried meats were the largest source of HA in the diet and chicken the largest source of HAs among different meat types. Estimated total HA intakes by male vs. female children were generally similar, with those by (0- to 15-year-old) children approximately 25% greater than those by (16+-year-old) adults. Race-, age- and sex-specific mean HA intakes were estimated to be greatest for African American males, who were estimated to consume approximately 2- and approximately 3-fold more PhIP than white males at ages <16 and 30+ years, respectively, after considering a relatively greater preference for more well-done items among African Americans based on national survey data. This difference in PhIP intakes may at least partly explain why prostate cancer (PC) kills approximately 2-fold more African American than white men, in view of experimental data indicating that PhIP mutates prostate DNA and causes prostate tumors in rats.

AN - 70867360; 11370940 AB - The Cardiff Atomic Weapons Establishment (AWE) plant, located in Cardiff, Wales, United Kingdom, used metallic beryllium in their beryllium facility during the years of operation 1961-1997. The beryllium production processes included melting and casting, powder production, pressing, machining, and heat and surface treatments. As part of Cardiff's industrial hygiene program, extensive area measurements and personal lapel measurements of airborne beryllium concentrations were collected for Cardiff workers over the 36-year period of operation. In addition to extensive air monitoring, the beryllium control program also utilized surface contamination controls, building design, engineering controls, worker controls, material controls, and medical surveillance. The electronic database includes 367,757 area sampling records at 101 locations and 217,681 personal lapel sampling records collected from 194 employees over the period 1981-1997. Similar workplace samples were collected from 1961 to 1980, but they were not analyzed because they were not available electronically. Annual personal mean sampling concentrations for all workers ranged from 0.11 to 0.72 micrograms per cubic meter (microg/m3) with 95th percentiles ranging from 0.22 to 1.89 microg/m3; foundry workers worked in the highest concentration areas with a mean of 0.87 microg/m3 and a 95th percentile of 2.9 microg/m3. Area sampling concentrations, as expected, were lower than personal sampling concentrations. Mean annual area sample concentrations for all locations ranged from 0.02 to 0.32 microg/m3. The area sample 95th percentile concentrations for all years were below 0.5 microg/m3. For the overwhelming majority of samples, airborne beryllium concentrations were below the 2.0 microg/m3 standard. Although blood lymphocyte testing for beryllium sensitization has not been routinely conducted among these workers, this metal beryllium processing facility is the only large scale beryllium facility of its kind to have experienced only one unique a case of clinical chronic beryllium disease (CBD) ascertained by traditional medical monitoring procedures. The treating physician determined that this lung disease was likely caused by a systems reaction resulting from a mound contaminated with beryllium. However, he could not rule out the potential for inhalation exposure. Over the 17 years of measurement data analyzed, on occasion, airborne beryllium concentrations have exceeded 2.0 microg/m3; however, the Cardiff experience demonstrates that strict and consistent adherence to exposure control measures that emphasized airborne and surface levels and appropriate engineering controls, work practices, and use of personal protective equipment appears to have successfully prevented the incidence of clinical CBD with the exception of one unique case.

We used cosmogenic nuclides to measure long-term erosion rates at climatically diverse sites in the Sierra Nevada, California, spanning 20-180 cm/yr in annual precipitation and 4-15 degrees C in mean annual temperature. Average erosion rates vary by only 2.5 fold across these sites and are not correlated with climate, indicating that climate only weakly regulates nonglacial erosion rates in mountainous granitic terrain.

This study was designed to identify the major technical factors that affect inter-scorer and inter-laboratory variability of the mESA assay. Two laboratories participated in this study (GSF and Lawrence Livermore National Laboratory, LLNL). Mice (102/ElxC3H/El) F sub(1) were exposed in one laboratory (GSF) to vinblastine (VBL; single intraperitoneal injection of 0, 0.5, 1.0 or 2.0 mg/kg), one of the 10 priority compounds of the Commission of the European Communities (CEC) Aneuploidy Program. Twenty-two days later the mESA assay was applied to analyze sperm aneuploidy. In the initial evaluation, small but statistically significant differences were found between the two laboratories in baseline frequencies and there was also disagreement in the determination of a VBL aneuploid effect. Therefore, experiments were conducted to identify the sources of the inter-laboratory differences and technical factors that affected assay reliability and the VBL study was repeated. A harmonization experiment was conducted by bringing the microscope scorers from both laboratories to the same site (LLNL) for a cross-training exercise. Following this exercise, a second group of VBL-treated and control mice were evaluated, and we concluded that VBL is not a sperm aneugen. Our research has identified scoring criteria as the major source of inter-laboratory variation and emphasizes the importance of strict technical controls for the mESA assay, including controlling slide preparations for treatment-induced reductions in sperm count, coding of slides and selection of statistical tests. These considerations are particularly important for the interpretation of small effects ( less than or equal to 2-fold) on sperm aneuploidy. Our findings suggest that 2-fold differences in frequencies can result from differences among scorers, samples and treatment groups, and are readily within the normal variation for the mESA assay. Such small differences should be viewed with caution until independently confirmed.

Eight parameters associated with eight carbon or nitrogen fluxes are determined during model calibration at specific sites for each of 17 vegetation types that cover the globe. Calibration is performed by an iterative method that brings calculated fluxes into agreement with observed fluxes over successive iterations. For the 17 vegetation types, calibration required a geometric mean number of 123 iterations for convergence with a geometric S.D. of 2.25. The minimum and maximum iterations required was 52 and 1060 for xeromorphic woodland and tropical evergreen forest, respectively. The parameter controlling gross primary productivity C sub(max) was found to be correlated with maximum projected leaf area index (plus cover of nonvascular plants) with a correlation coefficient of 0.90 (r super(2) = 0.81). Correlation of parameters with the input fluxes and average standing crops corresponding to the iteration equation was high in those cases in which temperature and precipitation were not explicit factors in the iteration equation. The parameters K sub(fall), L sub(nc), and N sub(loss) had correlation coefficients of 1.0 each with the appropriate ratio of the matching observed transfer flux and standing crop. In iteration equations with explicit dependence on temperature, soil moisture, and other factors, the correlation coefficients were less than 1.0 with these ratios; the parameters C sub(max), K sub(r), K sub(d), N sub(max), and N sub(up) had correlation coefficients of 0.83, 0.66, 0.60, 0.61, and 0.87, respectively. These correlation coefficients indicate the importance of environmental factors such as temperature and soil moisture in the calibration process and the robustness of the iteration method in determining parameters in systems with time-varying coefficients.

Ten volunteers each ate either 150 or 200 g of well-done chicken breast containing 9-21 microg of PhIP. Among the individual volunteers there is 8-fold variation in the total amount of metabolites and 20-fold variation in the relative amounts of individual metabolites, showing individual differences in carcinogen metabolism. PhIP metabolites were also detected in urine from a subject consuming chicken in a restaurant meal, demonstrating the method's sensitivity after real-life exposures. JF - Journal of chromatography.

AN - 70837935; 11348088 AB - The U.S. Environmental Protection Agency (EPA) now requires monitoring of oxygenate compounds in groundwater at leaking underground storage tank (LUST) sites nationwide. Three purge-and-trap gas chromatography methods most commonly employed for this purpose were tested, and their performance as a function of total petroleum hydrocarbon (TPH) content of the sample matrix was determined. Tests included a formal method evaluation, a round-robin study, and a split-sample study (424 groundwater samples). Consistently good results were achieved with EPA Method 8240B/60B (mass spectrometry) and ASTM Method D4815 (flame ionization detection) when five oxygenates were monitored in reagent water and gasoline. However, one protocol routinely employed for analysis of LUST samples had serious limitations: EPA Method 8020A/21B (photoiozination detection) was unfit for monitoring of tert-butyl alcohol (TBA) and frequently yielded false-positive (12-50% of samples) and inaccurate results when ether oxygenates were monitored in aqueous samples containing high concentrations of TPH (> 1,000 microg/ L). Thus, care should be taken in the analysis of LUST databases populated with EPA Method 8020/21 data because results reported for methyl tert-butyl ether (MTBE) in samples containing high levels of TPH have a high likelihood of being inaccurate or false-positive. For all three methods, detection limits determined in reagent water were sufficiently low for monitoring MTBE at the stringent primary (13 microg/L) and secondary (5 microg/L) action levels set by the state of California.

A methodology using multiple independent data sets was relied upon to define the hydrostratigraphic unit boundaries. The methodology employs an iterative process to minimize uncertainty in the correlations. Monitoring of the ground water system under stressed conditions during extraction well pumping and long-term pumping tests provided the most effective data set for identifying and verifying HSU boundaries. Hydrostratigraphic analysis identified low-permeability horizons within the alluvial sequence that exert significant control over ground-water flow and contaminant transport. These geologic features, which inhibit vertical hydraulic communication and contaminant migration, form the boundaries of the HSUs. At LLNL, the HSUs generally consist of a hydraulically interconnected network of higher-permeability deposits set within finer-grained, lower-permeability sediments. By identifying the primary hydraulic controls within the LLNL alluvial sequence, a hydrostratigraphic framework consistent with ground water flow and contaminant transport processes was established. The HSU framework has allowed for the mapping of a complex network of co-mingled plumes, each of which can be traced back to their respective source areas. Ground water cleanup systems at the site have been designed to treat and capture individual contaminant plumes, and are optimized with respect to their location, geometry, and mobility. This has proven a successful strategy for implementing the ground water cleanup based on the site remediation history. Work performed under the auspices of the U. S. Department of Energy by Lawrence Livermore National Laboratory under Contract W-7405-Eng-48.

The contamination results from multiple releases of volatile organic compounds (VOCs), primarily DNAPL trichloroethylene (TCE), during the 1960s and 1970s. A mixture of TCE (100-30%) and silicone oil (0-70%) was used as a heat exchange fluid in weapons testing at Lawrence Livermore National Laboratory (LLNL) Site 300, a test facility located in the Altamont Hills of central California. Leakage of the heat-exchange fluid from pipelines resulted in contamination of approximately 100,000 cubic meters of soil and sediment at concentrations up to 970 mg/kg. Perched ground water beneath the site contains dissolved TCE at concentrations approaching the solubility limit. Temporal changes in VOC concentrations indicate that intrinsic bioremediation of the TCE occurs as a result of silicone oils, whose fermentation yields hydrogen required for the microbial dechlorination of VOCs. The 3-D geologic model is based on integration of multiple data sets including borehole samples, geophysical logs, and surface outcrops. The integrated data sets are used to characterize the 3-D geometry of high conductivity fluvial channels encased in finer grained overbank deposits. The fine-grained, clay-rich sediments serve as a perching horizon for shallow ground water and may cause pooling of DNAPL. The 3-D-contaminant model is based on more than 300 soil samples collected in 28 boreholes with a maximum depth of 90 feet. Additional control for the contaminant model is provided by passive soil vapor data collected using GORE-Sorbers. Inclusion of the GORE-Sorber data helped minimize extrapolation in order to more accurately define the outer limits of soil contamination. Spatial and temporal modeling of VOCs in ground water is based on two years of monitoring data collected monthly for characterization of VOC concentrations, Eh, pH, dissolved oxygen, and other biogeochemical indicators. This model is used to optimize site cleanup in this complex hydrogeologic setting using a combination of ground water extraction, soil vapor extraction, and intrinsic bioremediation.

To assess the fate of chemicals already released and to properly design remedial alternatives to prevent future releases, we developed geospatial models to examine the distribution of contaminants residing in different geological media and to examine the impact of seasonal water table fluctuations over time. We used geospatial models as a hydrogeological analysis tool, for conducting internal review and design of remedial alternatives, for improving the understanding of the hydrogeological framework, for improved project planning, and to help communicate complex concepts to regulators and the public. We collected surface and subsurface lithology, borehole geophysics, hydraulic testing data, water level data, and chemistry data for tritium and uranium activity, metals, volatile organic compounds, and chlorine-36. Hydraulic parameters vary widely in the surrounding soil and rock due to weathering, fractures and joints, and heterogeneity of the material. The three-dimensional geospatial model incorporated surface and subsurface geologic data coupled with ground water and soil/rock chemistry as well as water level data, resulting in an integrated contaminant hydrogeologic model.We modeled the three-dimensional distribution of contaminants within the landfills, estimated the contaminant mass, and exported geospatial model data to build a numerical flow and transport model. An iterative process between the geospatial model and the numerical model was used to define initial and boundary conditions and to provide quality assurance.

The Bullion fault exhibits multiple geomorphic features suggestive of a recent surface rupturing event, whereas the 1999 surface rupture on the Lavic Lake fault within the Bullion Mountains is devoid of youthful geomorphic expression suggesting a long period of quiescence prior to the Hector Mine earthquake. We designed a paleoseismic trenching program to test these initial geomorphic observations and to better constrain the timing of past earthquakes on the 1999 surface rupture within the Bullion Mountains (Drainage Divide Site) and the Bullion fault where no rupture occurred in 1999 (Bullion Fan Site). At the Drainage Divide Site, the rupture traversed dissected alluvial aprons whose smooth, stable surfaces exhibited a well-formed, varnished desert pavement indicative of a Pleistocene age. These surfaces appear to have been disrupted by only the 1999 event. Trenches at this site revealed evidence for prior events that are likely on the order of tens of thousands of years old. Pending cosmogenic dating of the alluvial surface will provide a minimum age of the pre-Holocene penultimate event. In contrast, trenches across the Bullion fault at the Bullion Fan Site revealed a latest Holocene (< 2 ka) rupture. Paleoseismic and geomorphic observations suggest that the Bullion fault slip rate is significantly greater than the Lavic Lake fault.

Three of the four trenches, trenches A-C, were dug across the 1999 Hector Mine rupture; the fourth trench, D, was dug across a vegetation lineament that had only minor slip at its southern end in 1999. Trenches A-C exposed strata with only 1999 rupture; trench D exposed horizontal bedding along with local warping and offset by faults. Faults revealed in trench D line up with the vegetation lineament at the ground surface. A depositional contact about 80 cm below the ground surface acts as the upward termination of fault breaks in trench D. Thus, this contact may be the event horizon for a surface-rupturing event prior to 1999. Carbon 14 dates of three detrital charcoal samples, one from above (1940 + or - 40 radiocarbon years B.P.) and two below the event horizon (1730 + or - 40, and 3040 + or - 40 radiocarbon years B.P.) indicates that the earthquake associated with the faulting occurred a maximum of 1700 to 2000 years ago. The 1300-year age difference between the two samples below the event horizon suggests the potential for long residence time of detrital charcoal in the area. Coupled with a lack of bioturbation, the charcoal dates provide only maximum bounding ages and the recognized penultimate event may be considerably younger. A late Holocene age of the probable penultimate event at trench D is significantly younger than for the penultimate event as indicated at a more southerly trench site across the 1999 rupture. However, our inferred timing of an event is in agreement with an event on the Pisgah fault less than 2000 years ago. Thus, an event on the Pisgah fault may have interacted with the northern part of the Lavic Lake fault, or, at a minimum, there was a close timing of events on the Pisgah and northern Lavic Lake faults.

A distinctive well-sorted fine sand channel, dated as younger than A.D. 1600, served as a marker unit. Isopach mapping shows that the sand is channelized north of the fault, flowed as a fan complex across a broad fault scarp to the south, and is now offset 8.5 m. This displacement occurred principally as two large events and a smaller, fissuring event. We attribute the two larger events to the large regional earthquakes of 1766 and 1912. The smaller event may be the result of minor bleed-over slip from the 1893 M6.9 earthquake in the Gulf of Saros to the west. We conclude from our observations that most of the slip likely results from the 1766 and 1912 earthquakes. If each was similar in size, then about 4 m of slip can be attributed to each event. We also excavated six trenches at two sites along the 1999 Izmit rupture to study past earthquake history along that segment of the North Anatolian fault. We found evidence for at least two and probably three surface ruptures during the past 400 years. One of the past events is almost certainly the large earthquake of 1719, but the presence of a probable third event during the past 400 years leaves open the possibility that either 1754 or 1894 also ruptured the onshore portion of the fault zone. Release of about 4 m of seismic slip both west and east of the Marmara Sea this past century (1912, 1999) support the contention that Istanbul is at high risk from a pending large earthquake.

The structure of the Lake Tahoe basin is controlled by the North Tahoe-Incline Village and West Tahoe-Dollar Point fault zones, which cut late Quaternary lake sediments along numerous subparallel faults. The McKinney Bay megaslide scattered very large slide blocks of coherent Pleistocene sedimentary strata throughout the lake; deposited a 70-m-thick chaotic layer; and changed the basin morphology in the Late Pleistocene. Several subsequent generations of moderate to large landslides occur in McKinney Bay and the west Tahoe basin, attesting to several episodes of faulting and landslide activity. The sediments in Lake Tahoe are >300 m thick and are comprised of a 100 to 200 m basal sequence of well-bedded sedimentary strata presumably overlying granitic bedrock. The 70-m-thick chaotic layer is overlain by a 25 to 50 m sediment package whose reflectors can be correlated in profiles throughout the basin. Five 3-m piston cores were recovered; one in the footwall and two in the hanging wall of the North Tahoe fault and two in the deepest part of the lake. The longest core has a basal age of 12,600 14C yrs suggesting that a complete Holocene record is present. All of the cores contain a series of turbidites ranging from 2 to 30 cm thick. These layers can be correlated between cores based on color, lithology, texture, and magnetic properties. Eight distinctive turbidites occur above a 2-4 cm thick ash layer, identified as the 7600-8000 year Tsoyowata ash (pre-Mazama). Radiocarbon ages of macrofossils in the turbidites give an 8000 14C date for stratigraphically younger turbidites, suggesting a major sediment redistribution event about that time, possibly related to post-glacial collapse and landsliding in McKinney Bay. Together, these preliminary data suggest several intervals of landslide activity, perhaps seismically triggered, during the Holocene.

Using standard petrophysical relationships, these data can be interpreted to infer fluid behavior during production. High-resolution electrical resistance tomography (ERT) using multiple electrodes installed in boreholes has proven useful for characterization and process monitoring. Installing multiple downhole electrode arrays for high-resolution imaging can be costly on an oil field scale. For these cases, we are exploring the potential to image and track changes in the formation resistivity using the steel casings of existing boreholes as electrodes. The use of existing field infrastructure has several advantages in fielding and in survey fidelity. Data interpretation is accomplished using existing codes that treat the fully 3D case and model the casings embedded in a formation with realistic electrical structure. The surveys produce time dependent maps of the changes in formation resistivity caused by stimulation/production. Using vertical casings alone, only lateral resolution is obtainable. If horizontal casings are available, vertical resolution may be provided as well. In the first field example, we use Archie's law to calculate changes in the net oil/water ratio from a zone exhibiting ambient temperature changes in electrical resistivity.

Early-to-mid 20th century U.S. county-level consumption of BC for home heating was examined in relation to age-specific LCM, focusing on mortality in white women aged 40+ vs. 60+ years (among whom similar to 11% vs. similar to 5% ever smoked, respectively) during 1950 to 1954. To limit potential confounding due to variations in housing characteristics associated with counties where most vs. few homes used coal for heating, this study focused on domestic BC consumption only in 640 counties in which greater than or equal to 75% of homes used coal for heating in 1940. County-level data on domestic net tons of BC consumed per capita for the year 1918 were used to estimate lifetime residential exposure to BC smoke, and analyses focused on a 539-county subset for which estimated BC use remained fairly constant between 1918 and 1940. Significantly positive ecological associations were found between BC use and LCM risk in U.S. white women dying in 1950 to 1954 at age 40+ or 60+ y, after adjusting for age and combinations of 20 socio-demographic/geoclimatic variates. The apparent associations suggest that lifetime exposure to residential BC-combustion smoke may have increased LCM risk by about 25% to 50% among relatively highly exposed U.S. women. While these results must viewed in the context of the inherent limitations of any ecological study design, their consistency with results from studies on Chinese women suggests that some risk reduction might be achieved by increased (or universal) application of inexpensive measures to reduce or eliminate any indoor coal smoke in U.S. homes.

The relatively treatment effects of soil type, oxidant loading rate and dosing, and reaction period, as well as the use of surfactant or iron amendments and pH adjustment were examined using batch experiments with contaminated soil slurries. When KMnO sub(4) was applied to low organic carbon, acidic, or alkaline soils, at loading rates of 15-20 g/kg it was found to degrade consistently 90% or more of the alkene VOCs (TCE and PCE) and 99% of the polyaromatic SVOCs (naphthalene, pyrene, and phenanthrene). H sub(2)O sub(2) was more sensitive to contaminant and soil type and VOC treatment efficiencies were somewhat lower as compared with KMnO sub(4) under comparable conditions, particularly with the sandy soil and even when supplemental iron was added. In clay soil, H sub(2)O sub(2) with iron addition degraded over 90% of the SVOCs present compared with near zero in sandy soil, unless the pH was depressed to pH 3 and iron amendments were increased, whereby the treatment efficiency in the sandy soil was increased slightly. With both H sub(2)O sub(2) and KMnO sub(4), treatment efficiency increased to varying degrees as the oxidant loading rate (g/kg) and reaction time (h) were increased. Multiple oxidant additions or surfactant addition were not found to have any significant effect on VOC treatment efficiency. Also, very limited TCA treatment was observed with either H sub(2)O sub(2) or KMnO sub(4). JF - Journal of Environmental Engineering AU - Gates-Anderson, D D AU - Siegrist, R L AU - Cline AD - Envir.

Conventional colony-forming assays are rarely sensitive enough to examine small changes in cell survival and growth. Automated image-analysis techniques are limited to ca. 10 super(4) cells/plate. An alternative method involves encapsulation of single proliferating cells into ca. 35-75- mu m-diameter agarose gel microdrops (GMDs) that are randomly grouped, differential exposure of these groups, culture at 37 degree C for 3-5 days, and finally GMD analysis by flow cytometry (FC) to determine the ratio of GMDs containing multiple versus single cells as a measure of clonogenic survival. This GMD/FC assay was used to examine low-dose cell killing induced by a cooked-meat mutagen/rodent-carcinogen (MeIQx) in DNA-repair-deficient/metabolically-sensitive CHO cells. Results of conventional colony-forming assays using up to 30 replicate plates indicate a shouldered, threshold-like dose-response; in contrast, those obtained using the GMD/FC assay suggest 'hypersensitivity'-like nonlinearity in dose-response. The GMD/FC assay was also applied to human A549 lung cells after GMD-encapsulation and gamma radiation followed by culture for a total of 4 days, to examine survival after exposure to greater than or equal to 100 cGy delivered at a relatively low dose rate (0.18 cGy/min). Dose-response for clonogenic growth was again observed to be reduced with apparent nonlinear suggesting hypersensitivity between 0 and 50 cGy, insofar as doses of 5 and 10 cGy appear to be ca. fivefold more effective per unit dose than the 50- or 100-cGy doses used. The GMD/FC assay may thus reveal low-dose dose-response relations for chemical and radiation effects on cell proliferation/killing with implications for low-dose risk assessment.

Exposed bedrock and boulders are more abundant on steep slopes and may play an important role in regulating mountain erosion rates. Rapid transport of fine sediment on steep slopes exhumes resistant corestones which accumulate on the surface. The resulting boulder lag apparently shields the underlying soil and bedrock from erosion, even when the bedrock is deeply weathered and friable. Where steep slopes have an abundant boulder lag, they erode as slowly as gentler slopes nearby. In contrast, steep slopes lacking a boulder lag erode much more quickly than gentle slopes. Boulder armoring can modulate hillslope erosion such that erosion rates of summits, steep mountain flanks, and gentle footslopes are indistinguishable, thus permitting local relief and steep mountain slopes to persist for long periods of time.

Previous measurements of cosmogenic (super 21) Ne indicate higher cosmic-ray exposure ages for bulk samples than for some separated clasts or mineral separates. A possible interpretation for this difference in apparent exposure ages is a complex recent exposure history for Kapoeta. In this scenario some constituents are exposed to cosmic rays in a 2pi geometry as part of a larger body immediately preceding its 4pi exposure in a smaller body. To test this scenario we measured cosmogenic radionuclides in several clasts from Kapoeta. These measurements are consistent with a simple single-stage 4pi exposure history during which the entire inventory of cosmogenic radionuclides was produced. Taken together, these data are most consistent with a single-stage 4pi exposure lasting approximately 3Ma. This scenario is nevertheless consistent with models in which the exposure of some constituents of Kapoeta to energetic particles occurred at an earlier time, as is indicated by (super 21) Ne measurements. However, from our data we conclude that insubstantial quantities of cosmogenic radionuclides were inherited from this earlier irradiation; this earlier exposure to energetic particles must have predated the recent exposure by at least approximately 10 Ma to allow for the decay of the long half-life cosmogenic radionuclides.

The Nahef East fault is one of a series of fault scarps located along the 700 m high Zurim Escarpment, a major geomorphic feature. Samples at the top of the scarp have the highest nuclide concentrations (79 X 10 (super 4) atoms (g rock) (super -1) ); samples at the base have the lowest (11 X 10 (super 4) atoms (g rock) (super -1) ). Using chemical data from the samples, Nahef East fault scarp geometry, and surface and subsurface production rates for the (super 36) Cl-producing reactions, we have constructed a numerical model that calculates (super 36) Cl accumulation on a scarp through time, given a series of unique displacement scenarios. The resulting model (super 36) Cl concentrations are compared to those measured in the scarp samples. Faulting histories that result in a good match between measured and modeled (super 36) Cl abundances show three distinct periods of fault activity during the past 14 kyr with over 6 vertical meters of motion occurring during a 3 kyr time period in the middle Holocene. Smaller amounts of displacement occurred before and after the period of most rapid motion.

However, because the behavior of hydrocarbon plumes is usually poorly constrained at most leaking underground fuel tank sites in terms of release history, groundwater velocity, dispersion, as well as the biotransformation rate, demonstrating such a limitation in plume length is problematic. Biotransformation signatures in the aquifer geochemistry, most notably elevated bicarbonate, may offer a means of constraining the relationship between plume length and the mean biotransformation rate. In this study, modeled plume lengths and spatial bicarbonate differences among a population of synthetic hydrocarbon plumes, generated through Monte Carlo simulation of an analytical solute transport model, are compared to field observations from six underground storage tank (UST) sites at military bases in California. Simulation results indicate that the relationship between plume length and the distribution of bicarbonate is best explained by biotransformation rates that are consistent with ranges commonly reported in the literature. This finding suggests that bicarbonate can indeed provide an independent means for evaluating limitations in hydrocarbon plume length resulting from biotransformation.

The (super 10) Be and (super 26) Al model exposure ages (n = 68) delimit fan ages and suggest that deposition stopped after ca. 136, 15, 13, and 8 ka. One fan remains active and has undergone deposition throughout the Holocene. Soil development on three fans, where boulders were sampled for (super 10) Be and (super 26) Al analysis, also indicates distinct ages. Together, soil development and cosmogenic isotope data suggest that fan deposits correlate with the Tahoe and late Tioga glaciations. Soil profile development index values from Fish Springs are low compared with those determined elsewhere, suggesting relatively slow rates of soil formation for fan surfaces at Fish Springs and/or modification of soil profiles by surface processes during or following soil formation. Age estimates and measured offsets of the fans are consistent with a long-term vertical slip rate of 0.24+ or -0.04 m k.y. (super -1) for the Fish Springs fault over the past 300 k.y.

The study site, located at the Panola Mountain Research Watershed, has developed a granite-saprolite-soil regolith in which (super 14) C-gibbsite model ages deep within the profile (C-horizon) average about 8000 years. Near the surface (A- and B-horizon) (super 14) C-gibbsite model ages range from 2100 to 4200 years. Quartz has acquired (super 26) Al and (super 10) Be inventories suggesting a near-surface residence time of at least 90,000 years. This age disparity supports the notion that secondary minerals undergo significant recrystallization as weathering fronts propagate into the landscape. Combining the results of (super 14) C, (super 26) Al, and (super 10) Be analyses offers the potential to assess differential rates of chemical weathering and continental denudation to understand better the links between rates of silicate rock weathering, climate, and soil residence times.

A series of heaters were placed in a horizontal plane about 3 m from the top of the 3 mX3 mX4.5-m high block. Temperatures were measured at many points within and on the block surface and a suite of other measurements were taken to define the thermal and hydrologic response. Electrical resistance tomography (ERT) was used to map two-dimensional images of moisture content changes along four planes in the block. The ERT images clearly delineate the drying and wetting of the rockmass during the 13 months of heating and subsequent 6 months of cool down. The main feature is a prominent dry zone that forms around the heaters then gradually disappears as the rock cools down. Other features include linear anomalies of decreasing moisture content, which are fractures dehydrating as the block heats up. There are also examples of compact anomalies of wetting. Some of these appear to be water accumulation in fractures, which are draining condensate from the block. Others may be rainwater entering a fracture at the top of the block. During cool-down, a general rewetting is observed although this is less certain because of poor data quality during this stage of the experiment.

We consider a range of possible precursor mineral assemblages, varying with respect to the Fe-oxidation state of the initial anhydrous phases. The aqueous solutions produced by this alteration are generally strongly basic and reducing and a large quantity of H (sub 2) , and possible CH (sub 4) , gas can be released during aqueous alteration.

Mass-balance considerations for (super 26) Al and (super 10) Be show a five-fold LGM-to-Holocene increase in deep-water circulation in the study area, with little change in ocean productivity except during the deglaciation when it increased noticeably.

To estimate the pre-atmospheric size of the two showers, we determined the contribution of neutron-capture produced (super 36) Cl (half-life = 3.01X10 (super 5) years) and (super 41) Ca (1.04X10 (super 5) years) in the stone fraction. The measured activities of neutron-capture (super 36) Cl and (super 41) Ca, as well as spallation produced (super 10) Be and (super 26) Al, were compared with Monte Carlo-based model calculations. The largest shower, FRO 90174, includes eight fragments with an average terrestrial age of (100+ or -30) X 10 (super 3) years; the neutron-capture saturation activities extend to 27 dpm/kg stone for (super 36) Cl and 19 dpm/kg stone for (super 41) Ca. The concentrations of spallation produced (super 10) Be, (super 26) Al and (super 36) Cl constrain the radius (R) to 80-100 cm, while the neutron-capture (super 41) Ca activities indicate that the samples originated from the outer 25 cm. With a pre-atmospheric radius of 80-100 cm, FRO 90174 is among the largest of the Antarctic stony meteorites. The large pre-atmospheric size supports our hypothesis that at least 50 of the approximately 150 classified H5/H6-chondrites from the Frontier Mountain stranding area belong to this single fall; this hypothesis does not entirely account for the high H/L ratio at Frontier Mountain. The smaller shower, FRO 90001, includes four fragments with an average terrestrial age of (40+ or -10) X 10 (super 3) years; they contain small contributions of neutron-capture (super 36) Cl, but no excess of (super 41) Ca. FRO 90001 experienced a complex exposure history with high shielding conditions in the first stage (150 or =5 years. The lymphocyte assays detected an elevation over controls in average outcomes it clean-up workers: translocation rates were 46% higher when adjusted for age and smoking and HPRT mutant frequencies were were 16% higher when adjusted for age. The G PA assay did not detect an exposure effect. The results indicate that measuring frequency of translocations by FISH is preferred for low dose radiation, retrospective biochemistry.

AN - 70597967; 11215675 AB - Inherited BRCA2 mutations predispose individuals to breast cancer and increase risk at other sites. Recent studies have suggested a role for the APC I1307K allele as a low-penetrance breast cancer susceptibility gene that enhances the phenotypic effects of BRCA1 and BRCA2 mutations. To model the consequences of inheriting mutant alleles of the BRCA2 and APC tumor suppressor genes, we examined tumor outcome in C57BL/6 mice with mutations in the Brca2 and Apc genes. We hypothesized that if the Brca2 and Apc genes were interacting to influence mammary tumor susceptibility, then mammary tumor incidence and/or multiplicity would be altered in mice that had inherited mutations in both genes. Female and male offspring treated with a single IP injection of 50 mg/kg N-ethyl-N-nitrosourea (ENU) at 35 days of age developed mammary adenoacanthomas by 100 days of age. The female Apc-mutant and Brca2/Apc double-mutant progeny had mean mammary tumor multiplicities of 6.7+/-2.8 and 7.2+/-2.7, respectively, compared to wild-type and Brca2-mutant females, which had mean mammary tumor multiplicities of 0.1+/-0.4 and 0.3+/-0.5, respectively. Female ENU-treated Apc-mutant and Brca2/Apc double heterozygotes were also susceptible to premature ovarian failure. Thus, the inheritance of an Apc mutation predisposes ENU-treated female and male mice to mammary tumors and, in the case of female mice, to ovarian failure. These results indicate that mammary tumor development in Apc-mutant mice can progress independently of ovarian hormones. The Apc mutation-driven phenotypes were not modified by mutation of Brca2, perhaps because Brca2 acts in a hormonally dependent pathway of mammary carcinogenesis.

AN - 70597801; 11123188 AB - Allergic disease is a serious occupational health concern for individuals who have contact with laboratory animals. The principal respiratory symptoms include allergic rhinitis, conjunctivitis, and asthma. Urticaria (" hives") is the most common skin manifestation. The overall prevalence of allergic disease among laboratory animal handlers is about 23%, and respiratory allergy is much more common than skin allergy. Various studies have found annual incidence rates ranging from 2% to 12%. Prevention of animal allergy depends on control of allergenic material in the work environment. Personal protective equipment such as air filtering respirators should be used in addition to the other exposure control technologies where conditions require. Pre-placement evaluation and periodic medical surveillance of workers are important pieces of the overall occupational health program. The emphasis of these medical evaluations should be on counseling and early disease detection. The article gives recommendations for the content of the medical evaluations.

The UK's, France's, & Germany's individual objections to US deployment of national missile defenses are studied. It is contended that such deployment would promote the decoupling of US & European security interests, engender the perception of the US as a rogue superpower, & decrease the efficacy of French & British nuclear deterrents. The popular European position that the US would be less inclined to intervene on behalf of its European allies is strongly rejected. Although the possibility for US-Japan collaboration on developing a theater missile defense system remains intact, it is stated that Japan would not support US national missile defenses if Chinese opposition increases. South Korea's, Taiwan's, & Israel's reactions to US national missile defenses are also considered. It is concluded that the US's strategy for renegotiating the 1972 Anti-Ballistic Missile Treaty will significantly influence future international relations with its Asian & European allies. J. W.

In conjunction with these development goals, the Third World has obtained technology through the gray market & by acquiring missile development assistance from Russia, the People's Republic of China, & North Korea. This article examines the increasing threat that Third World missile capabilities pose to US security. US missile proliferation policies -- such as missile sanction guidelines, the Missile Technology Control Regime (MTCR), & US moves to cut off foreign assistance to countries such as Russia, China, & North Korea -- are examined. Several other nonproliferation approaches are also discussed. Finally, the article looks at the role that diplomacy plays in the missile proliferation context. It is concluded that antimissile systems, which would augment diplomatic efforts, are needed. 1 Table. K. A.

The conglomerates are also marked by intense fracturing down to microscopic scale. These features have traditionally been attributed to tectonic compression and pressure dissolution at cobble contacts. Sections through the cratered cobbles reveal pervasive internal fracturing, segments detached along concave spall fractures, and zones marked by quartz grains with planar deformation features. Comparison with results of impact experiments on artificial conglomerates suggests that these features were produced by internal accelerations, grain collisions, and spallation related to shock-wave propagation through inhomogeneous deposits. The proximity of the outcrops to the Azuara and proposed Rubielos de la Cerida impact structures suggests that shock deformation of conglomerates can provide an easily recognizable regional impact signature.

A Younger Dryas-aged peat is also examined to provide better understanding of the regional climatic history. Samples of surficial lake sediments from Wrangel Island and Chukotka aid in interpreting the lacustrine records. The modern spectra differentiate the herb-dominated tundra of Wrangel Island from the shrub tundras of the mainland and are unique when compared to other arctic assemblages. Analysis of the fossil data indicates that a herb-dominated tundra has been present on southern and central Wrangel Island since at least 11 ka BP. Comparison to modern palynological data implies little change in vegetation during the Holocene. The lacustrine interpretations contrast to those based on paleobotanical study of peats and alluvium, which suggest modern vegetation was not present until ca 4-3 ka BP. Pre-Holocene assemblages have high percentages of Cyperaceae pollen, perhaps indicating more moderate conditions. Summer climate is inferred to be warmer and moister than present during the latest Pleistocene and early Holocene. The pattern of postglacial warming on Wrangel Island is more like that from eastern Beringia than from other areas of western Beringia. Modern synoptic anomaly maps indicate that such a climatic pattern is reasonable and related to the presence of negative anomalies over western Beringia and a region of weaker positive 500 mb pressure centered over the Beaufort Sea.

AN - 52263594; 2001-012649 AB - Stable isotope profiles of fossil freshwater bivalve shells and mammal teeth provide a record of the seasonal delta (super 18) O variation in surface waters of the Himalayan foreland over the past 11 m.y. Between 3.1 and 10.7 Ma the delta (super 18) O of surface waters approached or exceeded 0 per mil standard mean ocean water (SMOW) in the dry season. Since 9.5 Ma the magnitude of seasonal variability in delta (super 18) O has remained essentially unchanged. Both observations imply that the Tibetan Plateau had attained sufficient elevation and area prior to 10.7 Ma to support a strong Asian monsoon. These data also imply that the delta (super 18) O of wet-season rainfall was significantly more negative (-9.5 per mil SMOW) prior to 7.5 Ma than after (-6.5 per mil SMOW). If this change is attributable to a lessening of the amount effect in rainfall, this agrees with floral and soil geochemical data that indicate increasing aridity beginning at 7.5 Ma.

Our data have been collected at lower temperatures than in previous studies and provide improved constraints on carbonate formation during relatively low-temperature processes ( approximately 10 (super 7) degrees C/Ma) occur only within the uppermost, melt-rich portions of an impact structure. Material deeper within the impact structure (where cooling is dominated by uplifted crustal material and where much of the formation of hydrothermal minerals is concentrated) cools much slower, typically at rates of approximately 10 (super 2) to 10 (super 3) degrees /Ma. Carbonates formed within this region would also only preserve approximately 1 mu m compositional zoning at formation temperatures of less than approximately 200 to 400 degrees C.

Progress in obtaining knowledge from that information reservoir has been steady, but has been hampered by the computationally intensive effort required to interpret the expression of those processes. Simulations are needed to understand the past and future time-dependent responses of these systems to natural and human perturbation, and are important for those instances in which the long term performance of sub-surface engineered facilities may impact future health and safety of the human population and the environment. We evaluated the vadose zone response to climate change for times periods between 100 and 100,000 years. The questions we considered were 1. What is the natural response time of a typical vadose zone system to local perturbations in temperature and infiltration flux at the ground surface, and 2. What is the expression of those perturbations as they propagate through the hydrological and geochemical systems? We conducted this study using a THC reactive transport code (NUFT-C) that simulates multi-component, multi-phase, saturated and unsaturated reactive transport for non-equilibrium, non-isothermal systems. The code runs on a massively parallel IBM SP-2 computer (1200 processors) allowing us to conduct high resolution simulations of complex systems. The characteristic response times for thick vadose zones to achieve steady-state conditions after a change in climate are on the order of thousands of years. This time is much longer than recently reported climate variability in the Southwest [Allen, 2000]. This implies that much of the vadose zone in the Southwest may be in the process of adjusting to relatively recent, post-glacial climate changes, and is not at steady-state. The THC response of such systems is path dependent. Uncertainty in these simulations reflect a paucity of rate constant data for most mineral phases of interest, a lack of knowledge concerning the three dimensional permeability structures, and the initial distribution of secondary mineral phases. These problems make it difficult to obtain accurate and precise initial and boundary conditions for simulations.

The amount of (super 14) C that remains in the atmosphere depends upon its decay rate and its exchange with the much larger carbon reservoirs of the ocean and biosphere. Measurements of (super 14) C/ (super 12) C in tree rings for the period 0 to 11,900 years before present provide a detailed calibration of radiocarbon years to calendar years. For the time interval 12,000 to 45,000 yrs. before present, (super 14) C/ (super 12) C analyses of varved sediments and paired (super 14) C/ (super 12) C and (super 230) Th/ (super 234) U age determinations of fossil corals have extended the tree-ring radiocarbon calibration to calendar years, albeit sparingly. Existing data illustrate large and sometimes sudden changes in atmospheric (super 14) C/ (super 12) C over the past 45,000 years compared to the 1950 reference value. Not all records are in agreement, however. Wire-line drill cores recovered from Holocene and late Pleistocene submerged coral reefs in the Caribbean and central Pacific contain pristine aragonite corals suitable for high precision radiocarbon and (super 238) U/ (super 234) U/ (super 230) Th age dating as well as (super 235) U/ (super 231) Pa age dating. The entire useful range of radiocarbon dating (0 to 45,000 yrs before present) is represented by samples recovered in these cores. Development of (super 238) U/ (super 234) U/ (super 230) Th and (super 235) U/ (super 231) Pa age dating techniques using a multi-collector magnetic sector ICP mass spectrometer simplifies the laboratory procedures for high precision age dating of corals, enabling detailed calibration of the radiocarbon time scale over the past 45,000 yrs. Originally developed for studies of the carbon cycle and solar magnetic and geomagnetic phenomena, the data provide an excellent radiocarbon calibration data set. Accelerator Mass Spectrometer (AMS) (super 14) C/ (super 12) C determinations have been made on the calibration samples at the Lawrence Livermore National Laboratory. The radiocarbon calibration program is available for interactive conversion of radiocarbon ages to calendar ages and is maintained at http://radiocarbon.ldeo.columbia.edu/ and updated twice per year.

Long-lived cosmogenic isotopes such as Cl-36 (half-life 300,000 a) and I-129 (half-life 15.7 Ma) have the age range and geochemical characteristics to provide important information in this context. We present here results of an extensive study of the hydrologic situation in the Fruitland Formation, CO, a well-studied formation with significant production potential for methane. I-129 content was determined in 80 wells, and Cl-36 in a subset of 40 wells from that area. The central part of the study area has I-129 ages up to 50 Ma, only slightly younger than the formation age in this region. Younger ages were found predominantly at the edges of the study area. Cl-36 ages are in good agreement with the general observations from the I-129 results, but provide more specific information on the time and direction of fluid movement in the last few Ma. The study shows that a large part of the hydrologic system has remained essentially undisturbed over a long time period and that the intrusion of younger waters is limited to marginal regions of the study area.

Pioneer studies of large Asian faults show that cosmogenic radionuclides ( (super 10) Be, (super 26) Al) provide an unparalleled tool to date surface features, whose offsets yield the longest records of recent cumulative movement. The technique is thus uniquely suited to determine long-term (10-100 ka) slip rates. Such rates, combined with coseismic slip-amounts, can give access to recurrence times of earthquakes of similar sizes. Landform dating--morphochronology--is therefore essential to understand fault-behaviour, evaluate seismic hazard, and build physical earthquake models. It is irreplaceable because long-term slip-rates on interacting faults need not coincide with GPS-derived, interseismic rates, and can be difficult to obtain from paleo-seismological trenching.

These observations are contrary to expectations, and have important implications for radionuclide fate and transport studies at the NTS. The 1973 Almendro test is a well-studied example. This test was detonated in fractured rhyolitic tuff more than 1-km underground, and >350 meters below the water table. The groundwater temperature measured within the Almendro test cavity in 1996 was still >150 degrees C, implying that energy transfer has been dominated by conductive heat loss. The delta (super 18) O value of the cavity fluid is presently shifted by +1.5 permil relative to ambient groundwater isotopic values. The lack of a correlated change in delta D implies the oxygen isotope shift is related to water-rock exchange, as seen in natural geothermal waters. Dissolved inorganic carbon (DIC) in groundwater from the Almendro cavity has a delta (super 13) C value of +27 permil, and a sample collected in the borehole above the cavity has a delta (super 13) C value of +45 permil. In comparison, delta (super 13) C values of groundwater from nearby environmental wells range from -1 to -11 permil. The Almendro delta (super 13) C data are generally consistent with a methanogenic process, such as CO (sub 2) reduction (e.g. CO (sub 2) + 8H (super +) + 8e (super -) --> CH (sub 4) + 2H (sub 2) O), which tends to enrich the residual DIC in (super 13) C. Work is in progress to determine whether this process is bacterially mediated or abiotic. Available evidence suggests the permeability of the surrounding rock is a key factor governing the development of environmentally restricted conditions. Following the Almendro test, near-field water levels were depressed by 250 m relative to pre-test conditions and required more than 20 years to recover. Local hydrothermal circulation of a limited groundwater supply in the cavity region may cause the system to self-seal as secondary minerals are deposited along fractures.

The slope of the regression between (super 3) He and (super 4) He and concentrations is near 2.8 R (sub a) (R (sub a) is the atmospheric helium isotope ratio), indicating that the subsurface source has a component of mantle helium. Hydrothermal springs and gas vents from Paoha Island have similar ratios, which suggests that discharge from this thermal system is the most important source. A (super 3) He mass balance indicated that below the deep pycnocline at 17 m, approximately 25 cc STP of (super 3) He accumulates each year ( approximately 90% from the influx of hydrothermal water and approximately 10% from the in situ decay of tritium). Although it is not retained because of gas transfer across the air-water interface, approximately 70 cc STP of (super 3) He is injected each year into the upper 17 m. When (super 3) He is used as a tracer, the influx of hydrothermal water below the deep pycnocline was estimated to be 0.045+ or -0.025 m (super 3) s (super -1) . Because the hydro-thermal water is fresher than Mono Lake, this influx causes the salinity of the monimolimnion to decrease by approximately 0.1 salinity units per year and may play a small but important role in the salinity budget of this layer, which is presently denser than and isolated from the surface water.

The LLNL SRDB provides not only a coherent framework in which to store and organize very large volumes of collected seismic waveforms, associated event parameter information, and spatial contextual data, but also provides an efficient data processing/research environment for deriving location and discrimination correction surfaces. The SRDB is a flexible and extensible framework consisting of a relational database (RDB), Geographical Information System (GIS), and associated product/data visualization and data management tools. This SRDB framework is designed to accommodate large volumes of data (almost 3 million waveforms from 57,000 events) in diverse formats from many sources (both LLNL-derived research and integrated contractor products), in addition to maintaining detailed quality control and metadata. We have developed expanded lookup tables for critical station parameter information (including location and response) and an integrated and reconciled event catalog data set (including specification of preferred origin solutions and associated phase arrivals) for the PDE, CMT, ISC, REB and selected regional catalogs. Using the SRDB framework, we are combining travel-time observations, event characterization studies, and regional tectonic models to assemble a library of ground-truth information and phenomenology (e.g. travel-time and amplitude) correction surfaces required for support of the ME/NA/WE regionalization program. We also use the SRDB to integrate data and research products from a variety of sources, such as contractors and universities, to merge and maintain quality control of the data sets. Corrections and parameters distilled from the LLNL SRDB provide essential contributions to the National Nuclear Security Administration Knowledge Base (NNSA KB) for the ME/NA/WE region and will improve capabilities for underground nuclear explosion monitoring. The LLNL information products will facilitate calibration of International Monitoring System (IMS) stations (primary and auxiliary), their surrogates (if not yet installed) and selected gamma stations necessary to complete the ME/NA/WE regionalization efforts. In addition to an overview of selected individual information products, we present an overview of our visualization, integration, validation, and organizational processes. Development of these processes and the LLNL SRDB was necessitated by both the very large amount of data and information involved, over 2 terabytes, and the varied data and research result formats utilized. Products assembled, integrated and validated using the LLNL SRDB are grouped into 5 major categories: 1. Reference and Contextual Information 2. Detection Data 3. Calibration and Ground Truth Data 4. Event Location Products 5. Event Identification Products.

The Rocky Flats is the most extensively exposed older piedmont alluvium in the vicinity of Denver. Correlative alluvial deposits and remnant erosional surfaces extend along the Front Range and tens of km east into the High Plains ca. 100 m above modern channels. Stratigraphic and geomorphic relations demonstrate that Rocky Flats Alluvium is younger than middle Pliocene and older than ca. 0.6 Ma. Regional paleontologic evidence and ages inferred from soil carbonate accumulation imply that deposits are early Pleistocene. Most workers suggest that the Rocky Flats and younger alluvial sequences correlate with glaciation in the Front Range, but alluvium in the type area was derived from an unglaciated 48 km (super 2) catchment. We collected a 9-sample sequence from the surface in oxidized, clast to matrix-supported gravel exposed temporarily during realignment of an irrigation canal. (super 10) Be activity in quartz grains from the sand fraction ranges from 3.12X10 (super 6) atoms/gram in a strongly developed Bt horizon buried 0.25 m below the surface to 0.77X10 (super 6) at -3.7 m. The A-horizon sample has lower than expected nuclide activity, consistent with mobile, recently emplaced surface sediment. Several scenarios constrained by muon production 60 degrees (super 10) Be production of 5.17 atoms g (super -1) y (super -1) fit the nuclide data equally well. A simple, steady erosion model (3.7 m My (super -1) ) and time since deposition of 2 My require high inheritance (2.1X10 (super 6) atoms g (super -1) ), equivalent to source basin erosion of 9.4 m My (super -1) . A no-erosion, exposure model implies deposition of alluvium at 0.2 Ma with inheritance (9X10 (super 5) atoms g (super -1) 10) Be), equivalent to source basin erosion at 22 m My (super -1) . Multi-stage models (stable fan surface, episodic erosion and deposition, then stable again) also fit the data well and are supported by geologic and pedologic evidence. The fit of such models is optimized by original deposition at ca. 1.5 Ma, stripping between 0.1 and 0.2 Ma, and inheritance of ca. 10 (super 6) atoms g (super -1) (super 10) Be. In all models, high density (2.4 g cm (super 3) ) and significant inheritance (>10 (super 6) atoms g (super -1) ) are key to good fits.

The combination of easily eroded lithologies, sparse vegetation, and monsoon-dominated rainfall result in rapid sediment generation and efficient sediment delivery from tributaries to the main Puerco channel. Measured activities of (super 10) Be range from 0.5 to 24X10 (super 5) atom g (super -1) and can be interpreted as rates of sediment generation that range from 2.1X10 (super 4) kg km (super 2) y (super -1) to 1.0X10 (super 6) kg km (super 2) y (super -1) , the equivalent of rock erosion at 8 to 400 m My (super -1) (rho = 2600 kg m (super 3) ). Basin to basin variance is high for smaller basins (<2000 km (super 2) ) but dampens at larger scales. The weighted average rock erosion rate for 16 headwater basins (mu = 440 km (super 2) ) is 100 m My (super -1) , similar to that (103 m My (super -1) ) calculated from (super 10) Be activity of sediment collected just below the confluence of the Rio Puerco's two largest sub-basins (14200 km (super 2) ). Our nuclide-based denudation estimates are consistent with previously published values determined by several different methods. Three results suggest an underlying dynamic equilibrium of upland sediment production and delivery of alluvium to the Rio Puerco over the Holocene. 1) (super 10) Be-based sediment generation rates are well correlated with bedrock lithology. 2) 20th century sediment yields for 5 USGS gages are similar to (super 10) Be-based estimates for the same drainage basins. 3) Fifteen samples from a 7 m vertical arroyo wall deposited over several thousand years, but exposed by channel incision in the late 19th century, have similar (super 10) Be activities (1.08+ or -0.10X10 (super 5) atom g (super -1) ) demonstrating that nuclide abundance in sediment does not change significantly over time. This study demonstrates cosmogenic nuclides have the potential to provide rapid assessment of long-term erosion rates not only in small, homogeneous basins but over a wide range of tributary areas, lithologies, and vegetation covers.

Thirteen 10-Be/26-Al analyses of boulders from the outermost moraine at Martha's Vineyard, MA indicate that the ice sheet reached its greatest extent about 25,000 cal yr B.P., approximately coeval with the coldest period of marine oxygen-isotope stage 2 and with Heinrich event 2. A further ten analyses from the Buzzards Bay Moraine to the north near Woods Hole, MA produced ages that cluster near 17,000 cal yr B.P. We found boulders with anomalously old exposure ages suggesting recycling of preexisting deposits in the outermost moraine, but boulder ages from the inner moraine are tightly grouped. These data and other radiocarbon dates from throughout New England indicate that fluctuations of this sector of the ice sheet were concordant with variations of North Atlantic climate: the ice sheet advanced rapidly to its maximum extent at the onset of coldest, glacial-maximum conditions ca. 25,000 cal yr B.P. and remained relatively close to this late Wisconsinan limit for ca. 8000 yr. before retreating.

The Smokies rise >1500 meters above adjacent valleys. Relief over most of the range is significant with very steep slopes feeding sediment into deeply incised river valleys. Mean annual rainfall is about 200 cm; the slopes are soil covered and heavily vegetated. We measured (super 10) Be in sediment (n = 22) from seven Great Smoky Rivers and in bedrock (n = 2) from outcrops on a hill slope and on the main drainage divide. Results suggest spatially homogeneous erosion (on the 10 (super 4) to 10 (super 5) year time scale). Bedrock outcrops (22+ or -4 m My (super -1) ) are more stable than drainage basins as a whole (31+ or -6 m My (super -1) ), consistent with the exposure of sampled rock above the soil-mantled hill slopes. There is no correlation between rates of erosion and basin drainage area, maximum relief, average elevation, and orientation. The lowest erosion rates were calculated for a slope bedrock out crop and a first order stream on the Raven Fork drainage basin (epsilon approximately 19 m My (super -1) ). Samples from other first order streams (n = 9, 1-11 km (super 2) ) yielded higher model erosion rates (29+ or -3 m My (super -1) ) that approached more closely the values calculated for samples from outlet streams of large basins (31+ or -6 m My (super -1) , n = 7, 64-191 km (super 2) ). The highest erosion rates (epsilon approximately 37 m My (super -1) ) were calculated for the Little Pigeon drainage basin, which is otherwise similar to the many rivers that drain the Smokies. Fission track studies by Naeser et al. (1999) imply time averaged (late Triassic to recent) denudation rates for the Great Smoky Mountain between 25-40 m My (super -1) . Sediment yield data collected during the 1930s by the U.S. Geological Survey for some rivers in the Smokies indicate, when considered as rock-surface erosion rates, denudation at rates between 21 and 65 m My (super -1) ; these historical rates likely reflect post colonial deforestation. Comparison of cosmogenic erosion rates with fission track and sediment yield data suggests that erosion rates have been similar over the 10 (super 2) to 10 (super 7) year time scales. The spatial and temporal uniformity of erosion rates preclude rapid recent uplift and incision and suggest landscape equilibrium with lithology and structural setting.

The detectability of seismic phases underpins the applicability and performance of discrimination and location algorithms by determining which phase observations are likely to contribute to discriminant and event location calculations. Seismic phase detectability is a function of expected phase signal-to-noise ratio (SNR), which, for a particular station, is a function of the phase amplitude spectrum and the noise spectrum at the station. We represent (map) phase amplitudes over broad regions for any given station with empirical (kriged) corrections superimposed on base values determined from an MDAC model. MDAC, which stands for Magnitude Distance Amplitude Correction, is a phase amplitude model that combines a source spectrum model, geometric spreading and attenuation. Ultimately, phase amplitude maps and station noise spectra will determine the geographic distribution of phase observation probabilities. These probabilities, in turn, determine the likelihood that data for particular discriminants will be available and should allow the construction of maps delimiting the geographic range of applicability of those discriminants. The second technical issue concerns the detection of events occurring at discrete sources, such as mines. This issue is of monitoring interest because mining explosions must be discriminated from earthquakes and nuclear explosions. The need for an efficient screen is particularly acute in mining districts, where explosions dominate event detections at observing stations. The same screening technique can be used to build reference populations of explosions for designing and testing other discriminant algorithms. Frequently, mining sources produce repetitive signals, a signal structure that can be exploited to increase dramatically the probability of detection at a given false alarm rate. The classical solution to problems of detecting known signals is the matched filter, which correlates a template waveform against a continuous data stream to detect occurrences of that waveform. However, signals from repetitive seismic sources often exhibit significant variation that degrades matched filter performance. Our solution to this problem is to use subspace detectors, which replace the matching template with a suite (subspace) of templates that are combined linearly to match occurrences of variable signals from a particular source. We outline template subspace design procedures that maximize the probability of detection for a fixed false alarm rate by varying the dimension of the subspace.

Calibration data are collected by 1) numerous seismic field efforts, many conducted under National Nuclear Security Administration (NNSA) Research Opportunity Announcement (ROA) and Defense Threat Reduction Agency (DTRA) Program Research and Development Announcement (PRDA) contracts, and 2) permanent seismic stations that are operated by national and international organizations. Local-network operators and international organizations (e.g. International Seismic Centre) provide location and other source characterization (collectively referred to as source parameters) to LLNL, or LLNL determines these parameters from raw data. For each seismic event, LLNL rigorously characterizes the uncertainty of source parameters. This validation process is used to identify events whose source parameters are accurate enough for use in calibration. LLNL has developed criteria for determining the accuracy of seismic locations and methods to characterize the covariance of calibration data sets. Although the most desirable calibration events are chemical and nuclear explosions with highly accurate locations and origin times, catalogues of naturally occurring earthquakes offer needed geographic coverage that is not provided by man-made sources. The issue in using seismically determined locations for calibration is validating the location accuracy. Sweeney (1998) presented a 50/90 teleseismic, network-coverage criterion (50 defining phases and 90 degrees maximum azimuthal gap) that generally results in 15-km maximum epicenter error. We have also conducted tests of recently proposed local/regional criteria and found that 10-km accuracy can be achieved by applying a 20/90 criterion. We continue to conduct tests that may validate less stringent criteria (which will produce more calibration events) while maintaining desirable location accuracy. Lastly, we examine methods of characterizing the covariance structure of calibration data sets. Each data set is likely to be affected by distinct error processes that result in a distinct covariance structure. We present covariance models for select data sets and demonstrate how these data sets can be integrated into one calibration-event catalog. LLNL has developed a robust magnitude calibration methodology for sparsely distributed regional stations using narrow band coda envelopes. This technique provides stable magnitudes for small events that make detection and identification calibration possible at low magnitudes. This approach has most recently been applied to International Monitoring System (IMS) stations located in Israel, Jordan and Egypt for events that span local and near regional distances. Our preliminary results show that a magnitude estimate from one station using the coda is equivalent to a network average of roughly 9 stations when using traditional magnitudes (e.g., m (sub b) (P), M (sub L) , M (sub d) ). The stability of the coda comes from measuring a long length of coda using a calibrated synthetic envelope as an empirical metric. We relate the non-dimensional coda amplitudes to an absolute scale by tying them to independent moment estimates from larger waveform-modeled events. Unlike most narrow band magnitudes, this approach yields an azimuthally averaged, moment-rate spectrum that is completely corrected for path and site effects. The resultant magnitudes from the spectra (e.g., M (sub w) and m (sub b) ) are fully transportable and do not suffer from regional bias.

As an example, a typical size used for an on-site inspection search area is 1,000 square kilometers or approximately 17 km accuracy, assuming a circular area. This level of accuracy is a significant challenge for small events that are recorded using a sparse regional network. In such cases, the travel time of seismic energy is strongly affected by crustal and upper mantle heterogeneity and large biases can result. This can lead to large systematic errors in location and, more importantly, to invalid error bounds associated with location estimates. Calibration data and methods are being developed and integrated to correct for these biases. Our research over the last few years has shown that one of the most effective approaches to generate path corrections is the hybrid technique that combines both regionalized models with three-dimensional empirical travel-time corrections. We implement a rigorous and comprehensive uncertainty framework for these hybrid approaches. Qualitative and quantitative validations are presented in the form of single-component consistency checks, sensitivity analysis, measures of robustness, and outlier testing, along with end-to-end testing of confidence measures. We focus on screening and validating both empirical and model-based calibrations as well as the hybrid form that combines these two types of calibration. We demonstrate that the hybrid approach very effectively calibrates both travel-time and slowness attributes for seismic location in the Middle East, North Africa, and Western Eurasia (ME/NA/WE). Furthermore, this approach provides highly reliable uncertainty estimates. Finally, we summarize the National Nuclear Security Administration (NNSA) validated data sets that have been provided to contractors in the last year.

The goal is to reduce the variance within the population of each type of event, while increasing the separation between the explosions and the other event types. We address this problem for both broad categories of seismic waves: body waves and surface waves. First, we map out the effects of propagation and source size in advance so that they can be accounted for and removed from observed events. This can dramatically reduce the population variance. Second, we try to optimize the measurement process to improve the separation between population types. For body waves we focus on the identification power of the short-period regional phases Pn, Pg, Sn and Lg, which can often be detected down to very small magnitudes. Many studies have shown that particular ratios of these phases, such as 6- to 8-Hz Pn/Lg, can effectively discriminate between closely located explosions and earthquakes. To extend this discrimination power over broad areas, we use our revised Magnitude and Distance Amplitude Correction (MDAC2) procedure. This joint source and path model fits the observed spectra and removes magnitude and distance trends from the data. The MDAC residuals are kriged to provide full 2-D path corrections by phase and frequency band. The MDAC residuals allow the exploration of all possible ratios and multivariate combinations of ratios for their discrimination power. We also make use of the MDAC spectra and the noise spectra to determine the expected detectability of each phase and use that to optimize the multivariate discriminants as a function of location. We quantify the discrimination power using the misidentified event trade-off curves and an equi-probable measure. We evaluate the correction surfaces using a cross-validation technique. The result is an end-to-end validation and discrimination performance measure for each station analyzed, and a set of measurement algorithms and correction surfaces that greatly improves discrimination. For surface waves we continue to make improvements in our regional group velocity tomography models. We have recently expanded our Rayleigh and Love wave dispersion measurements from the Middle East and North Africa into the European Arctic. The resulting tomography models now cover all of western Eurasia and provide high-resolution maps of group velocity from 10- to 100-seconds period. The maps also provide estimates of the expected phase spectra of new events that can be used in phase-match filters to compress the expected signals and improve the signal-to-noise ratio on surface wave magnitude (Ms) estimates. Phase match filters in combination with regional Ms formulas can significantly lower the threshold at which Ms can be measured, extending the Ms-mb discriminant. We have measured Ms in western Eurasia for thousands of events at tens of stations, with and without phase match filtering, and found a marked improvement in discrimination. Finally we are exploring the Ms-yield relation for the explosions in the dataset with announced yields.

This decrease is coincident with the Suess Effect, which is mostly due to the dilution of natural levels of (super 14) C by (super 14) C-free fossil fuel CO (sub 2) . This decrease is equal to that expected in surface waters of the subtropical gyres, and indicates that the surface waters of the North Pacific were in steady state with respect to long term mixing of CO (sub 2) during the past century. Correlation between Delta (super 14) C and North Pacific gyre sea surface temperatures indicates that vertical mixing local to Hawaii and the North Pacific gyre as a whole is the likely physical mechanism to result in variable Delta (super 14) C. Prior to 1920, this correlation starts to break down; this may be related to the non-correlation between biennial Delta (super 14) C values in corals from the southwest Pacific and El Nino events observed during this period as well.

Using empirical methods, we investigate the use of coda to determine moments and magnitudes using regional distance (to 2500 km) data from 21 stations in central Asia and China. We find source levels for bands between 33 s and 8 Hz from events recorded at Urumchi (WMQ) to be a factor of two more consistent for coda than for direct waves, for bands outside the microseism range. However, the anticipated path averaging of regional coda is insufficient to remove bias in all but the lowest frequency bands. We correct for path bias by spatially interpolating coda levels relative to m (sub b) (PDE). For higher bands (1 Hz), the spatial correction patterns vary by an order of magnitude and are similar to patterns obtained using direct L (sub g) . For the lowest band (20-33 s) the maximum spatial variation shrinks to under a factor of 4 and changes sign, reflecting effects other than crustal Q. Thus, the low frequency coda could be useful for correcting for source effects in empirical or tomographic path studies, which is currently performed using m (sub b) . After removing path bias from coda measurements, we find that amplitude measurement consistency between all 21 stations varies considerably from pair to pair (sigma = 0.12 to 0.37), with longer interstation distance, low-Q surroundings and poor site conditions yielding the least stable measurements. CMT based moments (Mw) derived from 20-33 s WMQ coda are verified by comparing with moments derived from waveform fitting studies (sigma = 0.18). We continue investigations into the transportability of regional magnitudes using the m (sub b) (L (sub g) ) scale devised by Nuttli. Previous work has shown that m (sub b) (L (sub g) ) is portable for earthquakes provided that L (sub g) attenuation is well calibrated for propagation paths. In this study, our focus shifts to explosion sources, and the question of transportability of m (sub b) (L (sub g) ) for different test sites. We revisit Nuttli's results, which were based on observations at far-regional and teleseismic distances, and depended critically upon accurate knowledge of the L (sub g) Qo. In this paper, measurements of m (sub b) (L (sub g) ) are reported for stations within 1000 km, and as such, errors due to uncertainties in the path correction are smaller than was the case for Nuttli's measurements.

The EO-induced water flux is proportional to the voltage gradient in a manner analogous to the flux dependence on the hydraulic gradient under Darcy's law. The proportionality constant, the soil electro-osmotic conductivity or k (sub eo) , is most easily measured in soil cores using bench-top tests, where flow is one-dimensional and interferring effects attributable to Darcy's law can be directly accounted for. In contrast, quantification of EO fluxes and k (sub eo) in the field under deployment conditions can be difficult because electrodes are placed in ground water wells that may be screened across a heterogeneous mixture of lithologies. As a result, EO-induced water fluxes constitute an approximate radial flow system that is superimposed upon a Darcy flow regime through permeable pathways that may or may not be coupled with hydraulic head differences created by the EO-induced water fluxes. A single well comparative tracer test, which indirectly measures EO fluxes by comparing wellbore tracer dilution rates between background and EO-induced water fluxes, may provide a means for routinely quantifying the efficacy of EO systems in such settings. EO fluxes measured in field tests through this technique at a ground water contamination site were used to estimate a mean k (sub eo) value through a semianalytic line source model of the electric field. The resulting estimate agrees well with values reported in the literature and with values obtained with bench-top tests conducted on a soil core collected in the test area.

We use effective medium theories to estimate effects of fractures on velocities for The Geysers rocks. We compare theoretical velocity estimates to laboratory measurements from the literature and our seismic velocity values obtained from 1992 earthquake data. We approximate the reservoir as being homogeneous in mineral composition, with a constant density of fractures that close with increasing lithostatic pressure. Thus, we expect low velocities near the surface, increasing with depth up to the values observed in the lab on intact samples, 5.5-5.7 km/sec. We use a one-dimensional inversion of P-waves to obtaine an "expected" P-wave velocity (Vp) and attenuation (Qp) relation as a function of depth for The Geysers rocks. We then use a three-dimensional Vp and Qp inversion to find anomalous zones within the reservoir. We find portions with anomalously high Vp and Qp, high Vp and low Qp, and low Vp and Qp. We interpret the regions with high Vp and Qp to be relatively less fractured, and the regions with low Vp and Qp to be significantly fractured. The high V and Q anomaly is centered on the zone of greatest pressure drop, and is mostly within the shallowest part of the felsite. The anomalous zones within the graywacke reservoir are on either side of the felsite, in areas of most moderate pressure depletion. More work is required to interpret the significance of these observations.

Measurements were performed to simulate test conditions with confining pressures up to 100 bars and temperatures to 145 degrees C. Measurements presented are a first step toward making the search for fractures using electrical methods quantitatively. Intact samples showed a gradual resistivity increase when pore pressure was decreased below the phase-boundary pressure of free water, while fractured samples show a larger resistivity change at the onset of boiling. The resistivity change is greatest for samples with the most exposed surface area. Analysis of a field test provided the opportunity to evaluate fracture detection using electrical methods at a large scale. Interpretation of electrical resistance tomography (ERT) images of resistivity contrasts, aided by laboratory derived resistivity-saturation-temperature relationships, indicates that dynamic saturation changes in a heated rock mass are observable and that fractures experiencing drying or resaturation can be identified. The same techniques can be used to locate fractures in geothermal reservoirs using electrical field methods.

First, geochemical modeling is used to determine the evolution of fluid chemistry at temperatures up to 300 degrees C when fluids are in contact with representative rocks of continental origin. Then, a kinetic crack growth model for quartz is used to predict growth rate for subcritical cracks in acidic and basic environments. The predicted growth rate is highly sensitive to temperature and pH in the ranges tested. At present, the model is limited to situations in which quartz controls the mechanical process of interest, such as well bore stability in silica cemented rocks and the opening of quartz filled veins to enhance permeability.

Past work at Ascension Island has shown that ship-towed airguns can be effectively used for local calibrations such as sensor location, amplitude and phase response, and T-phase coupling in the case of T-phase stations. At regional and ocean-basin distances from a station, the calibration focus is on acoustic travel time, transmission loss, bathymetric shadowing, diffraction, and reflection as recorded at a particular station. Such station calibrations will lead to an overall network calibration that seeks to maximize detection, location, and discrimination capability of events with acoustic signatures. Active-source calibration of hydroacoustic stations at regional and ocean-basin scales has not been attempted to date, but we have made significant headway addressing how such calibrations could be accomplished. We have developed an imploding sphere source that can be used instead of explosives on research and commercial vessels without restriction. The imploding sphere has been modeled using the Lawrence Livermore National Laboratory hydrodynamic code CALE and shown to agree with field data. The need for boosted energy in the monitoring band (2-100 Hz) has led us to develop a 5-sphere implosion device that was tested in the Pacific Ocean earlier this year. Boosting the energy in the monitoring band can be accomplished by a combination of increasing the implosion volume (i.e. the 5-sphere device) and imploding at shallower depths. Although active source calibrations will be necessary at particular locations and for particular objectives, the newly installed Diego Garcia station in the Indian Ocean has shown that earthquakes can be used to help understand regional blockages and the locations responsible for observed hydroacoustic reflections. We have analyzed several events with a back azimuth from Diego Garcia between 100 and 140 degrees. The Diego Garcia records show a pronounced reflection that correlates in travel time and back azimuth (calculated using the waveform cross-correlation of the tri-partite array elements to determine lag time across the array) with a reflector at the Saya de Malha Bank, on the Seychelles-Mauritius Plateau. We also show that to accurately predict blockage and reflection regions, it is essential to have detailed bathymetry in relatively small but critical areas.

The resulting model features a thick mantle lid with a positive velocity gradient. A significant shear wave low-velocity zone (6% velocity reduction) is required below the lid however the compressional velocities are not reduced. The paths studied lie along the fast axes of teleseismic shear wave splitting measurements and absolute plate motion. We observe splitting of upper mantle refracted shear-waves, with the transverse component slow relative to the radial component. In order to fit the shear wave arrivals and satisfy teleseismic shear-wave splitting observations we infer azimuthal anisotropy (maximum 1.6%) distributed throughout the mantle lid and low-velocity zone, with increasing anisotropy with depth.

In this paper, we present the results of equilibrium climate model simulations that indicate that the land-use change occurring over this period may largely explain this observed cooling, although other factors also could have played a significant role. The simulated annual mean cooling due to land-use change is 0.25K globally and 0.37 K for the Northern Hemisphere, suggesting that the cooling of the prior centuries could have been largely the result of anthropogenic interference in the climate system.

A wetland bioreactor was constructed with the wetland plants Typha spp., Scirpus spp., and Cyperus spp. These plants provided a habitat and a food source for the indigenous denitrifying microorganisms presumed responsible for the perchlorate and nitrate removal. Ground water contaminated with nitrate (68 mg/L) was collected from a well and injected with concentrations of potassium perchlorate similar to those found in several local wells (50 and 100 mu g/L). The water flowed continuously through the wetland bioreactor with hydraulic retention times (HRT) ranging from 0.5 to 400 h. Because microbial denitrification depends, in part, on the nature and amount of carbon available to the microorganisms, four carbon sources (dried leaf matter, dried algae, milk replacement starter, and sodium acetic acid) were evaluated. Analyses for perchlorate concentration in ground water were performed using negative electrospray mass spectrometry/mass spectrometry. Of the carbon sources tested, sodium acetic acid was the most efficient at accelerating the nitrate and perchlorate removal rates. The HRT required to remove perchlorate (100 mu g/L) to below the detection limit, without carbon source amendment, was 4 d. With the addition of sodium acetic acid (0.26 g/L) the required HRT decreased to 0.5 d. These results suggest that denitrifying microorganisms, supported in a wetland bioreactor amended with a carbon source, remove perchlorate from nitrate contaminated ground water.

We create an ensemble of forecasts by varying the initial (and boundary) conditions for the COAMPS meteorological model. The variations in the initial conditions must be consistent with analysis error. Optimally, the range of initial conditions would encompass the "true" atmospheric state, but which is never actually known. Our method for creating varying initial conditions is to use different global data sets to derive the necessary data. We use two models from the National Weather Service (the AVN and ETA models) and one from the Navy (the NOGAPS model). In addition to those data sets we perturb the data from those models, using a normally distributed random number at each grid point in the COAMPS model. We perturb the (u,v) wind components, the temperature and the moisture. The size of the perturbation is determined by the variability within that variable field. The forecasts, with a total of six simulations, are run for 48 hours. We then use the output from the COAMPS model to drive a Lagrangian dispersion model (LODI) for simulated releases. The results from a simulated release from hour 33 are shown in Figure 1. The center of the domain is Oakland airport and the basic on-shore wind is from the southwest. In three of the simulations, the plume goes over the top of the hills to the northeast, and in the other three the plume hugs the coastline and goes around those hills. The two solutions reflect a dependence on the Froude number, a ratio of the Kinetic energy to Potential energy. Higher Kinetic energy flow (Higher Froude number) flow goes over the top of the mountain, while lower Kinetic energy flow goes around the hills.

The airflow around buildings inevitably involves impingement and separation regions, building wakes with multiple vortices, and jetting effects in street canyons. The interference from adjacent buildings further complicates the flow and dispersion patterns. Thus accurate simulations of building-scale transport phenomena requires not only appropriate physics submodels but also significant computing resources. We have developed an efficient, high resolution CFD model for simulating chemical and biological releases around buildings. Our primary goal is to support incident response and preparedness in emergency response planning and vulnerability analysis.

A method was developed to estimate dietary HA levels using HA concentrations in experimentally cooked meats reported in the literature and meat consumption data obtained from a national dietary survey. Cooking variables (meat internal temperature and weight loss, surface temperature and time) were used to develop relationships for estimating total HA concentrations in six meat types. Concentrations of five individual HAs were estimated for specific meat type/cooking method combinations based on linear regression of total and individual HA values obtained from the literature. Using these relationships, total and individual HA concentrations were estimated for 21 meat type/cooking method combinations at four meat doneness levels. Reported consumption of the 21 meat type/cooking method combinations was obtained from a national dietary survey and the age-specific daily HA intake calculated using the estimated HA concentrations (ng/g) and reported meat intakes. Estimated mean daily total HA intakes for children (to age 15 years) and adults (30+ years) were 11 and 7.0 ng/kg/day, respectively, with 2-amino-1-methyl-6-phenylimidazo[4,5-b]pyridine (PhIP) estimated to comprise approximately 65% of each intake. Pan-fried meats were the largest source of HA in the diet and chicken the largest source of HAs among the different meat types.

Fracture surfaces were digitized in three dimensions before the fluid flow tests and after the tests. Digital reconstruction of the aperture then allowed numerical simulation of flow patterns, and digital comparison of surfaces before and after dissolution allowed mapping of patterns of dissolution. We observed that both mean aperture and fracture permeability decreased as a result of dissolution. Despite the low confining pressure, the experiments thus simulate dissolution in deeply buried formations, in contrast to the gaping and karst formation that occur under vanishingly low confining pressure in the shallow crust. We observed that the growth of new pathways for flow changed from stable to unstable as length scale increased. At the millimeter scale the fracture aperture evolved in stable fashion from a strongly heterogeneous arrangement of tortuous flow channels to a smoother topography, while at the scale of the full rock (50 mm), the aperture developed a single, broad flow channel. The scale dependence of the dissolution pattern may be the result of changes with scale in extent of reaction (i.e., the Damkoehler number) and in the relative importance of diffusion (the Peclet number). Finally, we also see evidence of a negative relationship between local fluid flux and local rate of dissolution in some locations in the fracture.

One-step and multistep outflow experiments, as well as quasi-static experiments were performed on identical, disturbed samples of a sandy and a loamy soil to evaluate the influence of flow rate on the calculated retention and unsaturated hydraulic conductivity curves. For the sandy soil, a significant influence of the flow rate on both the retention and unsaturated hydraulic conductivity characteristic was observed. At a given matric potential, more water was retained with greater applied pneumatic pressures. Matric potential differences of 10 to 15 cm (for given saturation) and water content differences of up to 7% (for given potential) could be observed between the slowest and the fastest outflow experiments, predominantly at the beginning of drainage. The hydraulic conductivity also increased with increasing flow rate for higher saturations, while a lower hydraulic conductivity was observed near residual saturation for the higher flow rates. We observed a continuously increasing total water potential gradient in the sandy soil as it drained, especially for high-pressure transient one-step experiments. This indicates a significant deviation from static equilibrium, as obtained under static or steady-state conditions. For the finer textured soil, these flow-rate dependent regimes were not apparent. A number of physical processes can explain the observed phenomena. Water entrapment and pore blockage play a significant role for the high flow rates, as well as lack of air continuity in the sample during the wettest stages of the experiment.

After accounting for the effects of groundwater velocity, source strength, and biases in the data collection process, chlorinated hydrocarbon plume lengths at sites where reductive dehalogenation was occurring were found to be significantly shorter on average, by roughly a factor of two, than those where it was not. Moreover, principal component analyses indicated significant differences in the behavior of chlorinated hydrocarbon plumes between sites with and without evidence of reductive dehalogenation, respectively. The advantage in examining plume behavior from this population-oriented perspective is that overall trends in plume behavior can be evaluated despite site-specific influences such as heterogeneities and unique release histories. Ultimately, it is these average trends that would be of the most interest to policymakers because they represent the ranges of conditions that will be encountered. This is especially important in the case of chlorinated hydrocarbons because they will biotransform at rates significant for appreciable natural attenuation only in certain instances.

AN - 72467699; 11106804 AB - The in vivo effects of chronic, ultra low dose rates of gamma radiation in mice were evaluated using fluorescence in situ hybridization and the in vivo micronucleus test. SWRxC57BL/6 mice were divided into nine exposure groups and continuously exposed to 0.5, 2.0 or 4.0cGy 137Cs per day for 30, 60 or 90 days; unexposed control mice were also included. Following exposure, blood samples were taken from each animal and the frequencies of micronucleated polychromatic erythrocytes (MPCE) and micronucleated normochromatic erythrocytes (MNCE) were determined using flow cytometry. Peripheral blood lymphocytes were cultured and analyzed by chromosome painting to determine translocation frequencies. A significant dose rate response was seen in translocations and both MPCE and MNCE. Comparisons were made between the three chronic dose rates and it was determined that there was no significant difference among translocation frequencies for each rate. However, a significant difference was found between the chronic exposures reported here and the fractionated daily exposures reported previously. Dose rate reduction effects, ranging from 3 at low doses to 14 at high doses, were found for chronic versus acute exposures. The possibility of gender effects was investigated in both micronucleus and translocation data. No gender effect was found in translocation induction, but a slight effect was suggested in micronucleus induction.

Sediments interpreted to reflect the last glacial maximum low-stand are approximately 150 m below present. Using a simple Airy isostatic model for hydroisostatic compensation and correcting for a minor tectonic component yields a local eustatic sea level lowering of approximately 105 m at the last glacial maximum. The deglacial sea level curve records two rapid sea level rises consistent with MWP1-A and 1-B as documented by the Barbados coral-based sea level curve. Comparison with relative sea level variations predicted by the ICE4G VM2 viscoelastic model have highlighted a deficiency in the model's predicted sea level history for this region. Detailed data-model comparisons of late Pleistocene sea level variations are necessary in the face of climate change induced sea level perturbations to determine regional and or systematic biases in the treatment of lithosphere viscosity and accurate predictions of future sea level.

The method relies on the electrolytic polarization induced at the boundary between soil and buried metal. This induced polarization (IP) produces a measurable phase delay between the electric current imposed on the subsurface and the resulting voltage distribution. If natural sources of induced polarization are small compared to those due to buried metal objects, then tomographs of impedance phase may be used to indicate where metal-soil polarization may be present. Three controlled tests were performed at a field site containing inert UXO buried in known locations. These tests produced a phase anomaly of about 20 milliradians that closely matched the known location of buried UXO objects. A fourth uncontrolled or blind test was performed under a building without prior knowledge of UXO presence. That test yielded phase anomalies as high as 75 milliradians. Limited excavation was performed at some of these anomalies but only a small amount (a few tens of grams) of metal was recovered. More extensive excavations are too costly until the building is razed.

Although these plants are abundant and ecologically important, little is known about their growth rate. We determined the growth rate for an individual rhodolith, Lithothamnium crassiusculum, from the southern Gulf of California through super(14)C analysis using accelerator mass spectrometry (AMS) to be 0.6 mm yr super(-1). This growth rate suggests large L. crassiusculum, which have been found with radii in excess of 6 cm, may live over 100 yr. Declines in the Delta super(14)C record associated with the large El Nino events of 1957, 1982, and 1992 indicate super(14)C analysis may lead to identification of important climate events in the more distant past. The ability to determine changes in past ocean circulation related to changes in past climatic conditions through AMS super(14)C analysis of rhodoliths would increase the geographic range of available climate records from the tropical oceans to the entire global ocean and potentially allow for the determination of past climate conditions from rhodoliths in fossil beds.

The specific in vitro rate of benzylsuccinate formation was >85% of the specific in vivo rate of toluene consumption. This is the first report of benzylsuccinate synthase activity in a methanogenic culture; the activity has previously been reported to occur in denitrifying, sulfate-reducing, and anoxygenic phototrophic bacteria.

AN - 72387007; 11058620 AB - BACKGROUNDHeterocyclic amine carcinogens are formed during the cooking of a number of foods, especially well-done meats. Lower temperatures and shorter cooking times can minimize the formation of these carcinogens, yet a major food safety concern is that pathogens in the meat must be thermally inactivated. This study investigated cooking techniques that minimize heterocyclic amine formation while simultaneously destroying contaminating bacteria.METHODSGround beef patties were inoculated with Escherichia coli K12 bacteria and fried to internal temperatures ranging from 35 degrees C to 70 degrees C in a skillet preheated to 160 degrees C, 180 degrees C, or 200 degrees C. Each patty was then analyzed for four common heterocyclic amines and for surviving bacteria. Additionally, the frequency of turning of the beef patty during cooking was varied (a single turn or multiple turns), length of time required for each patty to reach 70 degrees C was recorded, and heterocyclic amine levels were determined. An additional pan temperature of 250 degrees C was tested for its effect on heterocyclic amine formation but not on bacterial killing. Statistical tests were two-sided.RESULTSColony-forming bacteria were reduced by five orders of magnitude at internal temperatures greater than 60 degrees C, regardless of cooking method, and were completely inactivated at 70 degrees C. For patties turned just once, heterocyclic amine levels increased as the cooking temperatures increased. However, levels of heterocyclic amines were statistically significantly lower with turning every minute. For each pan temperature, patties reached 70 degrees C internal temperature sooner when they were turned every minute than when they were turned just once during cooking.CONCLUSIONLowering the pan temperature and turning the patties frequently can greatly reduce the formation of heterocyclic amines and can simultaneously achieve bacterial inactivation with little or no increase in cooking time, ensuring a product that is safe for human consumption.

Comparing a 33 yr sediment budget with 33 paired (super 10) Be and (super 26) Al analyses indicates that short-term sediment yield (113-138 t.km (super -2) .yr (super -1) ) exceeds long-term sediment production (74 + or - 16 t.km (super -2) .yr (super -1) ) by 53%-86%. The difference suggests that the basin is not in steady state, but is currently evacuating sediment accumulated during periods of more rapid sediment generation and lower sediment yield. Nuclide data indicate that (1) sediment leaving the basin is derived primarily from hillslope colluvium, (2) bedrock weathers more rapidly beneath a cover of colluvium than when exposed, and (3) long-term erosion rates of granite, schist, and amphibolite are similar.

These results are from experiments on duplicate laboratory experiments using synthetic, neutrally buoyant, abiotic, colloidal particles and two dense rhyolitic tuff cores. One core has a single, rough-walled fracture with an average aperture of 450 mu m. We have used a profilometer to measure the fracture topography and calculate aperture distributions and surface areas in the reconstructed core. The other core has a smooth, channelized slit that is a parallel-plate analogue to the fractured core. Identical tracer and particle pulses were injected into each core. Particle capture by electrostatic attachment in the parallel-plate core gives a retention capacity of 55 X 10 (super 9) particles m (super -2) . In the rough-walled fracture core, average particle transport rates are a full fracture volume faster than average tracer transport rates. Reynolds flow simulation indicates the presence of highly channelized fluid flow that likely contributes to this accelerated particle transport. Capture in the fractured core was 90 X 10 (super 9) particles m (super -2) ; retention capacity is unknown because particle concentrations in the effluent achieved a steady state value of only 85% of the injected concentration.

We have developed a method to quantify PhIP metabolites in human urine and have applied it to samples from female volunteers who had eaten a meal of cooked chicken. For this analysis, urine samples (5 ml) were spiked with a deuterium-labeled internal standard, adsorbed to a macroporous polymeric column and then eluted with methanol. After a solvent exchange to 0.01 M HCl, the urine extracts were passed through a filter, applied to a benzenesulfonic acid column, washed with methanol/acid and eluted with ammonium acetate and concentrated on a C sub(18) column. The metabolites were eluted from the C sub(18) column and quantified by LC/MS/MS. In our studies of human PhIP metabolism, eight volunteers were fed 200 g of cooked chicken containing a total of 27 mu g PhIP. Urine samples were collected for 24 h after the meal, in 6 h aliquots. Although no metabolites could be found in urine collected from volunteers before eating the chicken, four major human PhIP metabolites, N super(2)-OH-PhIP-N super(2)-glucuronide, PhIP-N super(2)-glucuronide, 4'-PhIP-sulfate and N super(2)-OH-PhIP-N3-glucuronide, were found in the urine after the chicken meal. The volunteers in the study excreted 4-53% of the ingested PhIP dose in the urine. The rate of metabolite excretion varied among the subjects, however, in all of the subjects the majority of the metabolites were excreted in the first 12 h. Very little metabolite was detected in the urine after 18 h. In humans, N super(2)-OH-PhIP-N super(2) glucuronide is the most abundant urinary metabolite, followed by PhIP-N super(2)-glucuronide. The variation seen in the total amount, excretion time and metabolite ratios with our method suggests that individual digestion, metabolism and/or other components of the diet may influence the absorption and amounts of metabolic products produced from PhIP.

AN - 72322385; 11024165 AB - Apurinic/apyrimidinic (AP) sites are common mutagenic and cytotoxic DNA lesions. Ape1 is the major human repair enzyme for abasic sites and incises the phosphodiester backbone 5' to the lesion to initiate a cascade of events aimed at removing the AP moiety and maintaining genetic integrity. Through resequencing of genomic DNA from 128 unrelated individuals, and searching published reports and sequence databases, seven amino acid substitution variants were identified in the repair domain of human Ape1. Functional characterization revealed that three of the variants, L104R, E126D and R237A, exhibited approximately 40-60% reductions in specific incision activity. A fourth variant, D283G, is similar to the previously characterized mutant D283A found to exhibit approximately 10% repair capacity. The most common substitution (D148E; observed at an allele frequency of 0.38) had no impact on endonuclease and DNA binding activities, nor did a G306A substitution. A G241R variant showed slightly enhanced endonuclease activity relative to wild-type. In total, four of seven substitutions in the repair domain of Ape1 imparted reduced function.

revisiting the well-mixed aquifer model AN - 50114964; 2000-073534 AB - Large-scale, lateral fluid flow through oceanic crust provides an explanation for regionally low heat flow in several seafloor settings. A well-mixed aquifer (WMA) model provides a quantitative and conceptual tool for explaining anomalously low heat flow based on an analytical representation of fluid and heat flow, assuming lateral fluid flow in basement in a layer directly below the ocean sediments. We present an extended well-mixed aquifer (EWMA) model that allows fluid flow at greater depths within the oceanic crust. Flow through a deeper permeable layer extracts more heat than equivalent flow through a shallower layer of equal thickness, and may help to reconcile global heat flow and seafloor permeability data, since deeper flow does not require velocities as great as shallow flow to account for the same heat loss, and thus permeability can be lower. Numerical simulations that test the hydrodynamic validity of the WMA and EWMA equations indicate that the analytical models provide reasonable approximations of large-scale, lateral heat transport when lateral fluid flow in the crust is confined to thin layers. The efficiency of lateral heat transport is reduced as vertical mixing within the lateral flow layer increases. Abstract Copyright (2000) Elsevier, B.V.

AN - 72259689; 10961911 AB - Transmitted de novo structural chromosomal abnormalities, the majority of which are paternally derived, can lead to abnormal reproductive outcomes as well as genetic diseases in offspring. We developed and validated a new multicolor FISH procedure (sperm ACM, which utilizes DNA probes specific for the alpha [1cen], classical, [1q12], and midi [1p36.3] satellites of chromosome 1) which utilizes DNA probes specific for three regions of chromosome 1 to detect human sperm that carry numerical abnormalities plus two categories of structural aberrations: (1) duplications and deletions of 1pter and 1cen, and (2) chromosomal breaks within the 1cen-1q12 region. In healthy men, the average frequencies of sperm with duplications and deletions were (a) 4.5 +/- 0.5 and 4.1 +/- 1.3 per 10(4) involving 1pter and (b) 0.9 +/- 0.4 and 0.8 +/- 0.3 per 10(4) involving 1cen, respectively. The frequency of sperm exhibiting breaks within the 1cen-1q12 region was 14.1 +/- 1.2 per 10(4). Structural aberrations accounted for 71% of the abnormalities detected by sperm ACM, which was significantly higher than numerical abnormalities (P=2x10-8). Our findings also suggest that, for healthy men, (a) sperm carrying postmeiotic chromosomal breaks appear to be more prevalent than those carrying products of premeiotic or meiotic breakage or rearrangements, (b) the high frequency of chromosome breaks measured after "fertilization" by the hamster-egg cytogenetic method already appear to be present and detectable within human sperm by FISH, and (c) there are nonrandom and donor-specific distributions of breakpoint locations within 1q12 in sperm. FISH facilitates the analysis of much larger numbers of sperm than was possible when the hamster-egg method was used. Therefore, FISH-based procedures for simultaneously detecting chromosomal breaks, rearrangements, and numerical abnormalities in sperm may have widespread applications in human genetics, genetic toxicology, and reproductive medicine.

Last updated - 2017-02-22 ER - TY - JOUR T1 - The use of temperature and the isotopes of O, H, C, and noble gases to determine the pattern and spatial extent of groundwater flow AN - 52288710; 2001-001891 AB - Isotopic tracer and temperature measurements at large volume cold springs in the central Oregon Cascades are used to understand the pattern of groundwater flow. Standard oxygen and hydrogen isotope interpretations are used to determine the mean recharge elevation for springs. Carbon and helium isotopes are used to measure the component of dissolved magmatic gas in the spring waters. Inferences from isotopic measurements are compared with temperature measurements made at the springs to determine whether groundwater circulates to shallow or deep depths in the subsurface. Integrating the measurements of tracers derived at the surface, tracers derived from the subsurface, and temperature measurements can thus be used to derive a three dimensional picture of groundwater flow.

And how old is it? AN - 51179815; 2002-080148 AB - Isotopic and temperature measurements from large, cold springs in the central Oregon Cascades are used to understand where this groundwater comes from and how old it is. In particular, we employ the isotopes of helium, carbon, oxygen, and hydrogen to address these issues and to understand some aspects of the subsurface geology in this region. We find that large, cold springs in the central Oregon Cascades are recharged near the Cascades crest up to 50 km from the springs. We also find that the large springs in the study area discharge water that is a few years old. Finally, we show that deeply circulating groundwater advectively transports geothermal heat and magmatic volatiles to several of the springs such as the Metolius River and Lower Opal Springs.

Different mixtures and packing geometries of quartz sand and 0 to 10% Na-montmorillonite clay were investigated using solutions of CaCl (sub 2) and deionized water. Two main regions of electrical conduction exist: a region dominated by surface conduction and a region where the ionic strength of the saturating fluid controlled conduction. For low fluid conductivities, the sample geometry was found to greatly affect the magnitude of the surface conductance. The influence of the microstructural properties on the electrical properties was quantified by estimating formation factors, Lambda -parameters, and surface conductances. The surface conductances estimated using the theory of Johnson et al. [1986] agreed well with measured values. We suggest that high and low bounds on the expected surface and bulk conductances in a natural system can be derived from the measurements on these artificial geometries.

AN - 72311083; 11018534 AB - Clostridial neurotoxins embrace a family of extremely potent toxins comprised of tetanus toxin (TeNT) and seven different serotypes of botulinum toxin (BoNT/A-G). The beta-trefoil subdomain of the C-terminal part of the heavy chain (H(C)), responsible for ganglioside binding, is the most divergent region in clostridial neurotoxins with sequence identity as low as 15%. We re-examined the alignment between family sequences within this subdomain, since in this region all alignments published to date show obvious inconsistencies with the beta-trefoil fold. The final alignment was obtained by considering the general constraints imposed by this fold, and homology modeling studies based on the TeNT structure. Recently solved structures of BoNT/A confirm the validity of this structure-based approach. Taking into account biochemical data and crystal structures of TeNT and BoNT/A, we also re-examined the location of the putative ganglioside binding site and, using the new alignment, characterized this site in other BoNT serotypes.

Sedimentologic evidence indicates that these ripples formed in a deep marine shelf setting well below the effects of meteorological processes. Combined with the impact-related origin of the spherules, this suggests that the ripples were formed by an impact-generated tsunami. To test if this geologic interpretation is reasonable, we have modeled anorbital ripple formation by impact-generated tsunami waves in the Hamersley basin. We assume a deep ocean target area, and that tsunami waves traveled from the target area unhindered to the Hamersley basin. Using melt spherule radius as an indicator, we infer a bolide diameter of 4.9 km. Assuming a bolide density of 2.6 and a velocity of 20 km/s, this impact would produce a crater 60.4 km in diameter. We modeled tsunami waves generated by the collapse of this crater, and propagated them into the Hamersley basin using shallow water wave theory. The wave models indicate tsunami waves created at impacts between 2000 and 8000 km from the Hamersley basin could have generated the observed anorbital ripples.

Here we report soil production rates for the first time at the base of a retreating escarpment, on the soil-mantled hilly slopes in the upper Bega Valley, southeastern Australia. Concentrations of (super 10) Be and (super 26) Al in bedrock from the base of the soil column show that soil production rates decline exponentially with increasing soil depth. These data define a soil production function with a maximum soil production rate of 53 m/m.y. under no soil mantle and a minimum of 7 m/m.y. under 100 cm of soil, thus constraining landscape evolution rates subsequent to escarpment retreat. The form of this function is supported by an inverse linear relationship between topographic curvature and soil depth that also suggests that simple creep does not adequately characterize the hillslope processes. Spatial variation of soil production shows a landscape out of dynamic equilibrium, possibly in response to the propagation of the escarpment through the field area within the past few million years. In addition, we present a method that tests the assumption of locally constant soil depth and lowering rates using concentrations of (super 10) Be and (super 26) Al on the surfaces of emergent tors.

At three sites, erosion rates and hillslope gradients are strongly correlated, increasing with proximity to fault scarps and river canyons, which appear to have accelerated local base-level lowering rates, and thus increased catchment erosion rates by up to 15-fold. At four other sites, far from fault scarps and river canyons, erosion rates are much more uniform and less sensitive to average hillslope gradient. Our measurements show that contrasts in landscape erosion rates cannot be inferred from hillslope gradients alone, because landscapes can evolve toward a state of erosional equilibrium, in which steep and gentle slopes erode at similar rates.

In order to study circulation and the redistribution of carbon in the ocean, we have simulated the uptake and redistribution of bomb radiocarbon in a state of the art ocean general circulation model. The model does reasonably well in simulating the gross surface prebomb distribution of radiocarbon as well as some of the finer details resolved during Geochemical Ocean Section Study and World Ocean Circulation Experiment observations. In areas of downwelling the simulated surface-ocean bomb (super 14) C maxima occur too early with too much amplitude. This indicates inadequate vertical mixing and coupling between the wind driven and deeper regions of the ocean with a piling up of radiocarbon and CO (sub 2) in the upper ocean. This inadequacy will hamper efforts to predict ocean CO (sub 2) uptake on decadal to centennial timescales, the equivalent ventilation time of the respective water masses. These results are not specific to our model and indicate a systemic problem in many ocean models. Copyright 2000 by the American Geophysical Union.

Such effects limit the lifetime of pressure vessels in nuclear power plants, and constrain the choice of materials for fusion-based alternative energy sources. Although these phenomena have been known for many years, the underlying fundamental mechanisms and their relation to the irradiation field have not been clearly demonstrated. Here we use three-dimensional multiscale simulations of irradiated metals toreveal the mechanisms underlying plastic flow localization indefect-free channels. We observe dislocation pinning by irradiation-induced clusters of defects, subsequent unpinning as defects are absorbed by the dislocations, and cross-slip of the latter as the stress is increased. The width of the plastic flow channels is limited by the interaction among opposing dislocation dipole segments and the remaining defect clusters.

Most previous chronologies focused primarily on relative weathering criteria and suggested that ice extent was restricted during the late Wisconsinan (ca. 24-8 ka). In contrast, by directly dating glacial features, we conclude that late Wisconsinan ice was far more extensive than previously believed. There are 36 gneissic boulders and 8 samples of ice-molded gneissic bedrock that yield late Wisconsinan (super 10) Be and (super 26) Al exposure ages for the last glaciation of Pangnirtung Fjord. The prominent Duval moraines, which were previously interpreted to represent a significant early Wisconsinan (100-60 ka) ice advance on southern Cumberland Peninsula, were actually deposited between 24 and 9 ka. Two boulders from a raised glaciomarine delta, stratigraphically related to the Duval moraines, date to about 10 ka. Two recessional moraines and striated bedrock along Pangnirtung Fjord, as well as erratics on the floor of the Kolik River valley, a tributary to Pangnirtung Fjord, indicate that deglaciation began between 12 and 9 ka. In situ produced (super 10) Be and (super 26) Al abundances indicate that ice filled Pangnirtung Fjord for about 15 k.y. (either continuously or intermittently) prior to 10 ka, which is compatible with (super 14) C chronologies for adjacent Cumberland Sound. Thus, our data support other recent studies that suggest the northern and southern margins of the Laurentide ice sheet were generally in phase during the latest Wisconsinan, contrary to earlier interpretations.

A puzzling result of geological investigations of the Lhasa Block over the past 2 decades has been the apparent lack of significant Tertiary deformation there. Perhaps the most important structural feature of the Lhasa Block is the south directed Gangdese Thrust System, which developed along its southern edge. The thrust system, which separates the Andean-type batholith of southern Asia from rocks of Indian affinity, is obscured at most locations across southeastern Tibet by back thrusts of the younger, north directed Renbu Zedong Thrust System. The best documented site where both thrusts are exposed occurs near Zedong (Zedong Window). Systematic geochronologic analyses were conducted in this area. U-Pb zircon dating of three samples of a synkinematically to postkinematically deformed hanging wall granitoid (the Yaja granodiorite) cut by the Gangdese Thrust indicates a crystallization age of 30.4+ or -0.4 Ma (2sigma ), thus placing an upper bound on the initiation of the thrust. U-Pb zircon dating of granitoid samples structurally higher in the Gangdese hanging wall yields emplacement ages of 42.5+ or -1.0 Ma and 48.9+ or -0.8 Ma (2sigma ), similar to other magmatic complexes within the Gangdese arc. Geochemical results are consistent with these plutons forming in the same environment as precollisional intrusions within the Gangdese batholith, suggesting a significant post-collisional input of juvenile heat. The (super 40) Ar/ (super 39) Ar thermochronology of samples from a vertical section through the hanging wall within the Yaja granodiorite, coupled with results of a numerical thermal model, indicate an average slip rate along the Gangdese Thrust of 7 mm/yr between 30 and 23 Ma and a minimum displacement of approximately 50 km. Farther east in the Zedong Window, thermal effects produced by later north directed thrust sheets of the Renbu Zedong system appear to have obscured thermal history signatures in the Gangdese hanging wall related to earlier south directed thrusting. Thermochronological results from this region indicate that thermal overprinting related to the north directed thrusting occurred between 25 and 10 Ma, consistent with previous estimates.

An analysis of the uncertainties shows that the measured uncertainties are 7 mu g/g are likely small area regions < (150 km) (super 2) . Using lunar topographic data, we have shown that the thorium abundances in the lunar high-lands and portions of South Pole-Aitken (SPA) Basin are larger for lower elevations. We have also studied a number of regions with anomalously high thorium abundances such as the northwestern region of SPA Basin, the crater Arago in western Tranquillitatis, and the Compton/Belkovich region in the northeastern highlands. The Compton/Belkovich region appears to be enriched with evolved rocks such as alkali anorthosite and currently represents the only such extended region on the Moon that has been identified.

The results show the presence of the linear uranyl structure UO (super 2+) (sub 2) with axial oxygen bond lengths of approximately 1.8 Aa, and features indicative of the multiple scattering of the axial O - U - O bonds in this structure. No evidence of longer-range order over pH 3.2-4.1 was found for montmorillonite adsorption of U (VI), and the equatorial oxygens form a single shell at approximately 2.4 Aa. In contact with amorphous SiO (sub 2) and gamma -Al (sub 2) O (sub 3) , the uranyl groups underwent a split in their equatorial shells at approximately 2.35 and 2.50 Aa, respectively and this is attributed to the formation of mononuclear, inner-sphere surface complexes. At pH > 6 on SiO (sub 2) , shells of Si and U occur at 3.1 and 4.0 Aa, respectively, and on gamma -Al (sub 2) O (sub 3) a U shell at 4.0 Aa with coordination number approximately 0.5 occurs. This indicates formation of polynuclear complexes at near-neutral pH in addition to the inner-sphere complexation occurring at lower pH values.

Radionuclide migration programs at the Nevada Test Site represent a twenty-five year systematic investigation of the diverse radiologic source terms residual from weapons testing and the evolution of the hydrologic source term which comprises those radionuclides dissolved in or otherwise available for transport by groundwater. The Nevada Test Site shares actinide source terms, correlative geology, an identical tectonic setting, similar climate, and a thick unsaturated zone with the adjacent proposed Yucca Mountain high-level waste repository and provides a natural laboratory to assess long-term radionuclide transport in the near field. Analog studies may ultimately help validate predictions of radionuclide transport from the Yucca Mountain repository.

These geoengineering schemes could reverse global annual mean warming; however, it is unclear to what extent they would mitigate regional and seasonal climate change, because radiative forcing from greenhouse gases such as CO (sub 2) differs from that of sunlight. No previous study has directly addressed this issue. In the NCAR CCM3 atmospheric general circulation model, we reduced the solar luminosity to balance the increased radiative forcing from doubling atmospheric CO (sub 2) . Our results indicate that geoengineering schemes could markedly diminish regional and seasonal climate change from increased atmospheric CO (sub 2) , despite differences in radiative forcing patterns. Nevertheless, geoengineering schemes could prove environmentally risky. Copyright 2000 by the American Geophysical Union.

It has had great impact in the geosciences and is now being applied in the biomedical fields. AMS measures radioisotopes such as super(14)C, super(3)H, super(41)Ca, and super(36)Cl, and others, with attomole sensitivity and high precision. Its use is allowing absorption, distribution, metabolism and elimination studies, as well as detailed pharmacokinetics, to be carried out directly in humans with very low chemical or radiological hazard. It is used in combination with standard separation methodologies, such as chromatography, in identification of metabolites and molecular targets for both toxicants and pharmacologic agents. AMS allows the use of very low specific activity chemicals ( less than or equal to 1 mCi/mmol), creating opportunities to use compounds not available in a high specific activity form, such as those that must be biosynthesized, produced in combinatorial libraries, or made through inefficient synthesis. AMS is allowing studies to be carried out with agents having low bioavailability, low systemic distributions, or high toxicity where administered doses must be kept low ( less than or equal to 1 mu g/kg). It may have uses in tests for idiosyncratic metabolism, drug interaction, or individual susceptibility, among others. The ability to use very low chemical doses, low radiological doses, small samples and conduct multiple dose studies may help move drug candidates into humans faster and safer than before. The uses of AMS are growing and its potential for drug development is only now beginning to be realized.

All three recombinant proteins were found to have similar enzymatic activity, comparable to the light chain purified from the whole toxin. The LC-pET30 protein was the most soluble and stable of the three fusion proteins, and it could be purified using a one-step affinity chromatography protocol. The purified protein was determined to be 98% pure as assessed by SDS-polyacrylamide gel. This protein has been crystallized and initial X-ray data show that the crystals diffract to 1.8 A.

High resolution electrical resistance tomography (ERT) using multiple electrodes installed in boreholes is useful for both site characterization and process monitoring. Recent design improvements permit such electrode arrays to be installed to depths appropriate for oil field deployments. In many cases, however, installing multiple downhole electrodes is too costly. For these cases, we are exploring the possibility of using the steel casings of existing boreholes as electrodes, with some success. Numerical simulations using different configurations of vertical steel casings alone or in combination with point electrode arrays indicate the range of resolution and sensitivity achievable with the ERT method. The results suggest that, although the spatial resolution and sensitivity are understandably lower than that obtained with high resolution arrays, it is possible to coarsely map the lateral extent of subsurface processes such as steam floods. Experiments using physical models support the numerical simulations. Casing-to-casing ERT surveys using abandoned vertical steel casings are being obtained in an oil field undergoing steam flood. The images reveal changes in electrical properties consistent with independent indicators of steam movement. Difference images show progressive changes in the electrical properties of the field. Resistivity decreases may indicate locations where the steam has substantially penetrated the field. By contrast, electrical resistivity increases during a period characterized by boiler outages.

However, environmental clean-up costs, as well as regulatory, political, and community issues can be stumbling blocks. New tools and methods are now available to resolve "distressed" site redeployment issues. Plus, federal and state regulators are now helping to streamline the environmental approvals' process for contaminated properties with redevelopment potential. This session will address the latest techniques to uncover redevelopment opportunities and: -reduce cleanup costs and minimize environmental liabilities; -manage regulatory issues and community affairs-structure and close optimum transactions. For example, in California several oil terminal and refinery sites have recently been repositioned in the marketplace for productive new uses. The key to moving these projects ahead was in coordinating the site reuse opportunities with remediation plans and effectively communicating the objectives to regulators, developers and communities. Case studies will be used to illustrate how corporations are succeeding in redeploying distressed assets.

Independent estimates of surface-water and deep-water reservoir ages in the New Zealand region since the last glacial period are presented. Compared to present-day values, surface-reservoir ages from 11,900 14C years ago were twice as large (800 years) and during glacial times were five times as large (2,000 years), contradicting constant surface age. Ages of glacial deep-water reservoirs were much older (3,000-5,000 years). The increase in surface-to-deep water age differences in the glacial Southern Ocean suggests that there was decreased ocean ventilation during this period. (Mod. auth. abstr.)

A baseline image, taken before steaming, shows the sequence of resistive sand and conductive shale and closely matches the induction log along the boreholes. Subsequently, for the past 15 months nine images have been made at regular intervals during steaming. Pixel by pixel differences between these and the baseline show changes in the formation electrical properties as a function of time with a spatial resolution between 5 and 10 feet. The ERT images have been compared to temperature logs, steam injection data and production data. We conclude that the images show three effects: First, there are changes close to the boreholes appearing only very early in the time sequence. These features are believed to be short-lived transient effects of drilling fluids close to the hole. Second, there are small magnitude anomalies in the upper pay zone which we believe are natural formation fluids moving as a result of pressure changes from the steam flood. Third, there are larger magnitude anomalies in the lower part of the pay zone which are correlated with high temperature at the boreholes. We believe these anomalies are high temperature fluids-perhaps steam-moving in individual sand units.

The well penetrated nearly 400 continuous feet of gas sand in the Upper Cretaceous Third Massive Sand. WCOC ran 5-1/2" casing to a depth of 8256' and perforated the upper 320' of this sand with 1128 holes. This thick massive gas sand is trapped as an erosional remnant beneath the base Meganos Gorge unconformity. The Gorge shale fill is the primary trapping mechanism, with lateral trapping provided by faulting. Calculations of a four-point isochronal back pressure test revealed an absolute open flow potential (AFOP) of 485,000 Mcf/d. The rate exceeded all California's gas deliveries to PG&E at the time, and was also one-half of PG&E's gas volume deliveries for all of its residential customers in California. A 165 acre production unit was formed, and the well commenced production in November 1983. The caloric rating of the gas is 1074 BTU (dry), and the total gas and condensate sales from the well have totaled $46 million, much of which was sold when gas prices reached $3-4 per/MMBTU.

Results from U/Th and (super 14) C dating of corals, surveying, and field mapping indicate several major changes in relative sea level over this period. Specifically, there is evidence for a relative sea level fall of 4.5 m about 3000 calendar years B.P., followed by relative sea level rises of nearly equal 1.5 m about 2400 calendar years B.P. and 0.5 m about 1200 calendar years B.P. and a subsequent relative sea level fall of 3 m some time in the past 1000 years. Since regional eustatic sea levels are believed to have been dropping gradually over this time frame, these observed changes in relative sea level are interpreted as reflecting alternating tectonic uplift and subsidence. Furthermore, the detailed structure and age relationships of the coral deposits indicate that both uplift and subsidence occurred rapidly, most probably as coseismic events with vertical displacements of 0.5 to 4.5 m. These events may be related to rupture on NW-SE trending reverse faults which have been mapped in the nearby Adelbert Range and possibly on NE trending cross faults which have been inferred from seismicity. This interpretation implies a much greater degree of tectonic instability and potential seismic hazard in the region than previously recognised, although the inferred coseismic vertical displacements are shown to be consistent with present-day local seismicity. In a broader context, the study illustrates how detailed analysis of vertical changes in coral reef structure and assemblages may be used as a sensitive indicator of changing relative sea level, capable of resolving century timescale events and reversals.

CaO-rich melt inclusions with these characteristics are preserved in Fo (sub 85-90) olivine, and compositional variations among the inclusions are interpreted to reflect mixing between melts such as those found in the most CaO-rich inclusions (present in Fo (sub 90) olivine) and melts similar to primitive "normal" island arc magmas (trapped in Fo (sub 85) olivine). Compilation of primitive island arc magmas from the literature shows that whole rocks and olivine-hosted melt inclusions with CaO contents >13 wt % are found in many arc volcanoes from all over the world in addition to Batan. These inclusions occur in lavas ranging from CaO-rich ankaramites to basaltic andesites with low-CaO contents (i.e., <13 wt %). The globally occurring CaO-rich inclusions and whole rocks comprise a group that although defined on the basis of their CaO contents is compositionally distinctive when compared to island arc lavas that have lower CaO contents; for example, they have lower FeO at a given SiO (sub 2) content than most arc lavas, and they are all nepheline normative, with normative nepheline contents positively correlated with CaO contents. Variations in CaO content and normative compositions of experimental partial melts of lherzolite related to changes of pressure, temperature, and source composition suggest that there are no conditions under which partial melting of peridotite can generate melts having CaO contents and other properties comparable to those observed for the primitive, CaO-rich arc-derived melts identified here. Although melting of peridotite at high pressure in the presence of CO (sub 2) can produce CaO-rich, silica-poor liquids, we consider it unlikely that this is responsible for producing the CaO-rich, silica-undersaturated melts considered in this study because there are significant differences in nearly all other compositional characteristics between the CaO-rich arc magmas and melts known or thought to be produced by melting of carbonated peridotite. Model major element compositions of partial melts of clinopyroxene-rich lithologies (mantle pyroxenites, lower crustal pyroxenites, and eclogites) calculated using the MELTS algorithm suggest that the most CaO-rich, nepheline-normative melt inclusions and whole rocks identified here could represent intermediate to high degree ( approximately 10-40 wt %) partial melts of pyroxenites at lower crustal to upper mantle pressures. Such a hypothesis is supported by the comparison between the trace element compositions of model pyroxenite sources of the Batan CaO-rich melt inclusions and naturally occurring pyroxenites. The most likely source of the primitive CaO-rich, silica-undersaturated arc melts identified here is lower crustal and shallow upper mantle pyroxene-rich cumulates from arc environments because these cumulates have CaO concentrations at the upper end of the range observed for mantle pyroxenites. They are therefore more likely to yield partial melts with the restricted range of remarkably high CaO contents of the most CaO-rich inclusions and whole rocks identified here. Moreover, these cumulates often contain amphibole, which would lower their solidus temperatures relative to the anhydrous pyroxenite equivalents to values more consistent with those expected in deep crustal or shallow subarc environments.

AN - 71045364; 10772862 AB - Apurinic/apyrimidinic (AP) endonuclease Ape1 is a key enzyme in the mammalian base excision repair pathway that corrects AP sites in the genome. Ape1 cleaves the phosphodiester bond immediately 5' to AP sites through a hydrolytic reaction involving a divalent metal co-factor. Here, site-directed mutagenesis, chemical footprinting techniques, and molecular dynamics simulations were employed to gain insights into how Ape1 interacts with its metal cation and AP DNA. It was found that Ape1 binds predominantly to the minor groove of AP DNA, and that residues R156 and Y128 contribute to protein-DNA complex stability. Furthermore, the Ape1-AP DNA footprint does not change along its reaction pathway upon active-site coordination of Mg(2+) or in the presence of DNA polymerase beta (polbeta), an interactive protein partner in AP site repair. The DNA region immediately 5' to the abasic residue was determined to be in close proximity to the Ape1 metal-binding site. Experimental evidence is provided that amino acid residues E96, D70, and D308 of Ape1 are involved in metal coordination. Molecular dynamics simulations, starting from the active site of the Ape1 crystal structure, suggest that D70 and E96 bind directly to the metal, while D308 coordinates the cation through the first hydration shell. These studies define the Ape1-AP DNA interface, determine the effect of polbeta on the Ape1-DNA interaction, and reveal new insights into the Ape1 active site and overall protein dynamics.

The formation of the mutagenic amine IFP (determined to be 2-amino-(1,6-dimethylfuro[3,2-e]imidazo[4,5-b])pyridine) was investigated by varying heating time, heating temperature, and precursors. With an optimized mixture of glutamine, creatine, and glucose, heated at 200 degrees C for 60 min, 2 mg of IFP was purified for studies to define its structure. Trideuteriomethyl-IFP was made from trideuteriomethylcreatinine in the model system for use in LC-MS detection of IFP in foods. Analysis of well-done meats purchased from restaurants showed about half to contain IFP at levels from 1.4 to 46 ng/g of cooked meat, demonstrating human exposure to this mutagen.

AN - 71109667; 10813652 AB - Tetanus toxin belongs to a family of clostridial protein neurotoxins for which there are no known antidotes. Another closely related member of this family, botulinum toxin, is being used with increasing frequency by physicians to treat severe muscle disorders. Botulinum toxin has also been produced in large quantities by terrorists for use as a biological weapon. To identify small molecule ligands that might bind to the targeting domain of tetanus and botulinum toxins and to facilitate the design of inhibitors and new reagents for their detection, molecular docking calculations were used to screen a large database of compounds for their potential to bind to the C fragment of tetanus toxin. Eleven of the predicted ligands were assayed by electrospray ionization mass spectrometry (ESI-MS) for binding to the tetanus toxin C fragment, and five ligands (45%) were found to bind to the protein. One of these compounds, doxorubicin, was observed to have strong hydrophobic interactions with the C fragment. To check the ligands for their ability to compete with ganglioside binding, each was also tested using a GT1b liposome assay. Doxorubicin was the only ligand found to competitively bind the tetanus toxin C fragment with an appreciable binding constant (9.4 microM).

This T-dependent fractionation is 1000 ln alpha = 2.67 (10 (super 6) /T (super 2) K) + 4.75, where azurite (sub (CO) (sub 3)) denotes the CO (sub 2) liberated by acidification of azurite and corrected to calcite standards. Oxygen isotope data for 46 azurite samples from 44 localities around the world suggest formation from meteoric waters. Both carbon and oxygen isotope delta values for natural azurites are consistent with values recorded for speleothems, soil carbonates and malachite, suggesting that azurite commonly derives much of its carbon from isotopically light soil CO (sub 2) . The new oxygen isotope thermometer indicates that most natural azurites form within + or - 10 degrees C of modern local air T. A few azurite samples from deposits of massive sulphides yield apparent T up to 48 degrees C, which are significantly higher than modern air T. It is suggested that the higher apparent T record the heat produced during oxidation of sulphides. The results indicate that exothermic oxidation of massive sulphide deposits can produce shallow subsurface T < or = 25 degrees C higher than mean local air T.

AN - 52339071; 2000-048748 AB - Two techniques for resolving the conductance of an electrically conductive asthenosphere are presented. The first technique combines observatory electromagnetic data in the period range of the daily variation and longer, which provides penetration depths of 400 km and deeper, with laboratory data of the conductivity of upper mantle materials. The conductance can be estimated by this technique, but the geometry--e.g. the exact depth--is not resolved. The second technique extends the classical magnetotelluric (MT) tensor estimation and decomposition to the period range 1000-30000 s. If an electrical asthenosphere exists, then in this period range the electromagnetic field penetrates into it (1000 s) but also through it (30000 s). The concept of regional strike directions which has been successfully used to obtain crustal anisotropy directions is again employed at these long periods. The surprising result is that in the depth range of the asthenosphere a strong directional dependence of the conductance again occurs. Although large arrays will be necessary in order to prove that this is really conductivity anisotropy in the asthenosphere, first field results from arrays 100-200 km in extent are encouraging. The concept of a superposition of crustal and upper mantle anisotropy explains to some extent why earlier magnetotelluric determinations of the asthenosphere had little success: only in the fortunate case where a MT experiment was performed not parallel to the direction of the crustal conductor, but parallel to the asthenospheric one, is the second structure resolved. Electrical anisotropy in the uppermost mantle supports the concept of intracrystalline water, which allows for a contribution of hydrogen diffusivity to the conductivity of olivine: this diffusivity is highly anisotropic with respect to the crystal axis, and if the crystals are partly aligned, the conductivity measured with MT is also direction-dependent.

The results were used to calculate the partial molal thermodynamic quantities of the organic liquid aqueous dissolution reactions: Delta G sub(soln), Delta H sub(soln), Delta S sub(soln) and Delta C sub(p soln). Calculated values for these quantities at 298 K for TCE are: Delta G sub(soln) = 11.282 ( plus or minus 0.003) kJ/mol, Delta H sub(soln) = -3.35 ( plus or minus 0.07) kJ/mol, Delta S sub(soln) = -49.07 ( plus or minus 0.24) J/mol K, and Delta C sub(p soln) = 385.2 ( plus or minus 3.4) J/mol K. Calculated values for these quantities at 298 K for PCE are: Delta G sub(soln) = 15.80 ( plus or minus 0.04) kJ/mol, Delta H sub(soln) = -1.79 ( plus or minus 0.58) kJ/mol, Delta S sub(soln) = -59.00 ( plus or minus 1.96) J/mol K and Delta C sub(p soln) = 354.6 ( plus or minus 8.6) J/mol K. These thermodynamic quantities may be used to calculate the solubility of TCE and PCE at any temperature of interest. In the absence of direct measurements over this temperature range, the Henry's Law constants for TCE and PCE have been estimated using the measured aqueous solubilities and calculated vapor pressures.

We used five sediment cores and radiocarbon dating to develop a chronology of Holocene hydrologic events for the Ritterbush Pond basin, northern Vermont. Chemical and physical analyses allow us to identify 52 distinct layers of predominately inorganic sediment that represent terrestrially derived material delivered to the pond by runoff events. The thickness of some layers suggests hydrologic events at least equal in size to, and probably much larger than, any storm or flood recorded during nearly 300 yr of written regional history. Layer thickness and frequency and, by analogy, storm size and recurrence, change through the Holocene. The largest events occurred 2620, 6840, and 9440 calibrated (super 14) C years before present (cal (super 14) C yr B.P.). The most frequent hydrologic events occurred in three periods; 1750 to 2620, 6330 to 6840, and >8600 cal yr B.P. The recurrence interval of layer deposition during stormy periods averages 130 + or - 100 cal yr, whereas the recurrence interval during less stormy periods is longer, 270 + or -170 cal yr. The Ritterbush Pond event record illustrates the potential of inorganic lacustrine sediment to serve as a proxy record for estimating paleoflood frequency and deciphering climate change.

Archeological evidence has shown that this highly developed civilization collapsed abruptly near 4170 + or - 150 calendar yr B.P., perhaps related to a shift to more arid conditions. Detailed paleoclimate records to test this assertion from Mesopotamia are rare, but changes in regional aridity are preserved in adjacent ocean basins. We document Holocene changes in regional aridity using mineralogic and geochemical analyses of a marine sediment core from the Gulf of Oman, which is directly downwind of Mesopotamian dust source areas and archeological sites. Our results document a very abrupt increase in eolian dust and Mesopotamian aridity, accelerator mass spectrometer radiocarbon dated to 4025 + or - 125 calendar yr B.P., which persisted for approximately 300 yr. Radiogenic (Nd and Sr) isotope analyses confirm that the observed increase in mineral dust was derived from Mesopotamian source areas. Geochemical correlation of volcanic ash shards between the archeological site and marine sediment record establishes a direct temporal link between Mesopotamian aridification and social collapse, implicating a sudden shift to more arid conditions as a key factor contributing to the collapse of the Akkadian Empire.

However, for certain frequencies and distances the near- and intermediate-field terms of the Earth's response becomes important. We developed a criterion to estimate the relative importance of these terms for horizontally layered Earth models by comparing reflectivity synthetic seismograms, computed with just the far-field response (far-field terms only), with the complete response (all terms included). The frequency and range dependent differences of these two responses are quantified by measuring the difference between synthetics for regional and local earthquake scenarios, the 1992 Little Skull Mountain, Nevada (M (sub w) 5.7) and 1997 Calico Hills, Nevada (M (sub w) 4.0) earthquakes. For these crustal earthquakes, we found that the near-field term becomes important when the minimum frequency, f (sub n) (Hz) of the simulation at hypocentral distance r (km) is f (sub n) = gamma cr (super -1) where a reasonable crustal velocity for c is 5.8 km/sec and gamma is the fraction of a wavelength estimated in this study to be nearly equal 0.6. The far-field response converges to the complete response for frequencies greater than f (sub n) .

One way to make these techniques more tractable when the objective function depends on a time-consuming flow and transport model is to employ an empirical approximation of the model. The current study examines the impact of employing artificial neural networks (ANNs) and linear approximators (LAs) on the quality and quantity of solutions obtained from simulated annealing-driven searches on two different ground-water remediation problems. The quality of results obtained when ANNs served as substitutes for the full model was consistently comparable to that of results obtained when the full model itself was called in the course of the search. The effect on quality of results of substituting an LA for the full model was more variable.

Edge shift data from the X-ray absorption near-edge structure (XANES) spectra showed that the average Mn valence in these particulates is similar to 2.2. Using a principal component analysis (PCA) algorithm, the number and type of probable species contained in these particulates were determined to be three, consisting of Mn sub(3)O sub(4), MnSO sub(4) times H sub(2)O, and a divalent manganese phosphate, Mn sub(5)(PO sub(4))[PO sub(3)(OH)] sub(2) times 4H sub(2)O. The proportions of these Mn phases in each particulate sample were evaluated quantitatively using least-squares fitting (LSF) of the experimental XANES spectra with linear combinations of these principal component (model compound) spectra. Two groups of Mn-bearing particulates may be distinguished: group I having 4-9 wt % of Mn sub(3)O sub(4) and exhibiting a single intense first major absorption maximum at the Mn K-edge and group II containing 15-22 wt % of Mn sub(3)O sub(4) and exhibiting a doublet absorption maximum at lower intensity. Fourier transforms of the EXAFS signals were found to corroborate the XANES results.

Radioisotope labels have drawbacks that hamper their applications: (i) perceived radiation hazards of reagents, (ii) regulatory requirements and disposal problems of working with radioactive materials, and (iii) short shelf-life of the labeled reagents. The advantage of isotopic labeling is the incorporation into analytes without altering structure or reactivity, as is often the case with ELISA or fluorescent detection systems. We developed a format for isotope label immunoassay with the long- life isotope super(14)C as the label and accelerator mass spectrometer (AMS) as the detection system. AMS quantifies attomole levels of several isotopes, including super(14)C. With this exquisite sensitivity, the sensitivity of an immunoassay is limited by the K sub(d) of the antibody and not the detection system. The detection limit of the assays for atrazine and 2,3,7,8-tetrachlorodibenzo-p-dioxin was 2.0 x 10 super(-10) M and 2.0 x 10 super(-11) M, respectively, approximately an order of magnitude below the standard enzyme immunoassay. Notably, <1 dpm (0.45 pCi) of super(14)C-labeled compound was used in each assay, which is well below the limit of disposal (50 nCi per g) as nonradioactive waste. Thus, endogenous reporter ligands quantified by AMS provide the advantages of an RIA without the associated problems of radioactive waste.

Previous investigation of this fault scarp used weathering rinds to characterize the displacement history of the scarp by the identification of bands of similar rind thickness on the scarp. The variation of rind thickness on the scarp did not follow a simple model of increasing thickness on the older (higher) parts of the scarp, which suggests that the geomorphic history of this scarp is complicated. The rind thickness distribution and morphology of the scarp imply that spalling of thin basalt sheets and chemical weathering were the primary agents of modification of scarp morphology. One interpretation of the rind study is that this scarp may have had a history of periodic displacement followed by long period of scarp degradation. This is in general agreement with other fault studies on the southern Colorado Plateau that estimate that recurrence intervals may be from 5-100 ky. Core samples collected from a Pleistocene basalt flow offset by the fault are being processed to measure the abundance of 36Cl. Numerical modeling of 36Cl accumulation in the scarp over time for several displacement histories will be compared with the measured accumulations to evaluate various displacement models.

It is a region of active extension in the midst of a collisional tectonic setting, and contains the most extensive glacial history found anywhere in the tropics. The Cordillera Blanca detachment fault is a major west-dipping normal fault that strikes north-south along the western side of the Cordillera Blanca. In order to calculate slip rates and recurrence intervals along this fault, we conducted surveys of offset geomorphic features using a laser theodolite total station. We surveyed an offset moraine crest and profiles across moraine crests at Quebrada Cojup, and tectonically-generated fluvial terraces at Quebrada Querrococha. We also used GPS surveys to map moraine crests at Cojup, and fault and terrace surfaces at Querrococha. At Cojup, the survey of the fault scarp shows a vertical displacement of approximately 25 m on a surface that has been dated at approximately 14.7 ka using cosmogenic radionuclides. The average vertical offset rate revealed here is approximately 1.7 mm/yr. Relative dating using topographic profiles to estimate the extent of moraine crest diffusion suggests multiple episodes of moraine deposition. Differentially corrected GPS files allowed us to construct a map of moraine crests along the south side of Cojup, showing at least 4-5 crests of different ages. At Querrococha, we surveyed a sequence of 5 terraces found on the footwall side of the fault (Schwartz, 1988). Based upon profiles constructed along the strike of the valley and cross-sections running perpendicular to this, spacing between each of these terraces has been estimated at approximately 2-3 m. This represents the amount of offset generated during each tectonic event. We are currently in the process of constructing depth profiles for the cosmogenic radionuclides 26Al and 10Be on the 3 oldest terraces. This will allow us to determine the age of each terrace surface, so that we can then calculate a recurrence interval for terrace forming earthquakes.

A suite of new Accelerated Mass Spectrometer (AMS) (super 14) C dates provides chronologies that differ from earlier age models and suggest correlation between conditions in the Japan Sea, changes in the North Pacific, and global sea level and climate changes. We present evidence that reduced salinity of the Japan Sea surface water during the late Pleistocene was due primarily to the increased importance of the precipitation-evaporation balance at a time when lowered sea level had reduced water exchange with the Pacific to a few percent of the present value.

The model can simulate several simultaneously occurring attenuation processes including aerobic and anaerobic biological degradation processes. The developed model was applied to analyze field-scale transport and biodegradation processes occurring at the Area-6 site in Dover Air Force Base, Delaware. The model was calibrated to field data collected at this site. The calibrated model reproduced the general groundwater flow patterns, and also, it successfully recreated the observed distribution of tetrachloroethene (PCE), trichloroethene (TCE), dichloroethylene (DCE), vinyl chloride (VC) and chloride plumes. Field-scale decay rates of these contaminant plumes were also estimated. The decay rates are within the range of values that were previously estimated based on lab-scale microcosm and field-scale transect analyses. Model simulation results indicated that the anaerobic degradation rate of TCE, source loading rate, and groundwater transport rate are the important model parameters. Sensitivity analysis of the model indicated that the shape and extent of the predicted TCE plume is most sensitive to transmissivity values. The total mass of the predicted TCE plume is most sensitive to TCE anaerobic degradation rates. The numerical model developed in this study is a useful engineering tool for integrating field-scale natural attenuation data within a rational modeling framework. The model results can be used for quantifying the relative importance of various simultaneously occurring natural attenuation processes.

We determined the splitting parameters phi (fast polarization direction) and delta t (splitting delay time) for waves that sample the above- and below-slab regions: teleseismic *KS and S, ScS waves from local deep-focus events, as well as S waves from intermediate-focus events that sample only the above-slab region. All but one of the *KS stacks for the BANJO stations show E-W fast directions with delta t varying between 0.4 and 1.5 s. However, for *KS recorded at most of the SEDA and PISCO stations, and for local deep-focus S events north and south of BANJO, there is a rotation of phi to a more nearly trench parallel direction. The splitting parameters for above-slab paths, determined from events around 200 km deep to western stations, yield small delay times (< or =0.3 s) and N-S fast polarization directions. Assuming the anisotropy is limited to the top 400 km of the mantle (olivine stability field), these data suggest the following spatial distribution of anisotropy. For the above-slab component, as one goes from east (where (super *) KS reflects the above-slab component) to west, phi changes from E-W to N-S, and delay times are substantially reduced. This change may mark the transition from the Brazilian craton to actively deforming (E-W shortening) Andean mantle. We see no evidence for the strain field expected for either corner flow or shear in the mantle wedge associated with relative plate motion. The small delay times for above-slab paths in the west require the existence of significant, spatially varying below-slab anisotropy to explain the *KS results. The implied anisotropic pattern below the slab is not easily explained by a simple model of slab-entrained shear flow beneath the plate. Instead, flow induced by the retrograde motion of the slab, in combination with local structural variations, may provide a better explanation.

This high-elevation site is situated on a sloping plateau between mountains to the west and a river valley to the east. The local climate, which favors clear skies, low humidity, and light winds, permits terrain-generated winds to develop frequently. During the night, winds that are oriented along the valley frequently overlie shallow (<50-m deep) drainage winds. Results indicate the nighttime direction shear between the levels at 92 and 12 m above ground exceeds 60 degree 20% of the time and exceeds 20 degree 50% of the time. Daytime shear is more modest: it is less than 20 degree 90% of the time. The effects of vertical wind direction shear on plume transport are studied by performing two model simulations of release at 50 m above ground level during a period when strong directional shear persisted for several hours. In the simulation using the full wind profile, southwest winds above a shallow drainage layer initially transport material to a community located 2 km to the northeast of the release. However, when only the 12-m wind is used, the model predicts that the material impacts a different community located 10 km to the southeast. This simulation demonstrates that ignoring the vertical shear effects can result in serious mistakes in responding to an emergency.

We conducted a field competition experiment in which Amsinckia seedlings were transplanted into forty 0.64-m super(2) experimental plots of exotic annual grassland or restored perennial grassland. The perennial grassland plots were restored using mature 3 cm-diameter plants of the native perennial bunchgrass Poa secunda planted in three densities. The exotic annual grassland plots were established in four densities through manual removal of existing plants. Both grass types reduced soil water potential with increasing biomass, but this reduction was not significantly different between grass types. Both grass types significantly reduced the production of Amsinckia inflorescences. At low and intermediate densities (dry biomass per unit area of 20-80 g /m super(2)), the exotic annual grasses reduced Amsinckia inflorescence number to a greater extent than did Poa, although at high densities (>90 g/m super(2)) both grass types reduced the number of Amsinckia inflorescences to the same extent. The response of Amsinckia inflorescence number to Poa biomass was linear, whereas the same response to the annual grass biomass is logarithmic, and appeared to be related to graminoid cover. This may be because of the different growth forms exhibited by the two grass types. Results of this research suggest that restored native perennial grasslands at intermediate densities have a high habitat value for the potential establishment of the native annual A. grandiflora.

Accounting for differences in the spatial coverage of satellite and surface measurements reduces this differential, but still leaves a statistically significant residual of roughly 0.1 degree C per decade. Natural internal climate variability alone, as simulated in three state-of-the-art coupled atmosphere-ocean models, cannot completely explain this residual trend difference. A model forced by a combination of anthropogenic factors and volcanic aerosols yields surface-troposphere temperature trend differences closest to those observed.

Both case studies compared images of electrical resistivity before and after barrier installation. Barrier materials were imaged as anomalies which were more electrically conducting than the native sandy soils at the test sites. Although the spatial resolution of the ERT was insufficient to resolve flaws smaller than a reconstruction voxel (50 cm on a side), the images did show the spatial extent of the barrier materials and therefore the general shape of the structures. To verify barrier performance, ERT was also used to monitor a flood test of a thin-wall grout barrier. Electrical resistivity changes were imaged as a saltwater tracer moved through the barrier at locations which were later found to be defects in a wall or the joining of two walls.

The thermal expansion of single-crystal Al (sub 2) O (sub 3) (corundum) was measured up to 1000 K with the differential laser-interferometer. The changes in the distance between two faces of a stepped shape sample are measured. The main feature of the apparatus is simultaneously monitoring two fringe signals that are 90 degrees out of phase. This improvement of the basic laser-interferometer allows us to remotely measure the thermal expansion of minerals with high precision. The overall sensitivity with which we can detect changes in length is about 1/100 of the wavelength of the He-Ne laser (1/100 of 0.6328X10 (super -6) m). After adjusting for errors caused by heat, the thermal expansion data measured with the differential laser-interferometer are in good agreement with previous reports. Use of this apparatus allows the investigation of the high-temperature thermodynamic properties of important rock-forming minerals.

However, small events are likely to be recorded on a sparse subset of IMS stations at regional- to upper-mantle distances (less than 30 degrees ), and sparse-network locations can be strongly effected by travel-time errors that result from path-specific velocity model inaccuracies. In an effort to improve sparse network location capability, we outline a procedure that applies empirical corrections to travel times determined with an appropriate velocity model. More specifically, Bayesian kriging and calibration events (constrained with a global network) are used to estimate epicenter-specific travel-time corrections. For a test (sparse) network of stations, we calculate travel-time residuals for the calibration events relative to the ak135 velocity model. Travel-time residuals are assigned to the respective calibration epicenter, forming a set of spatially varying travel-time correction points. The spatial set of correction points is declustered to reduce the dimension of the observations with minimal reduction in accuracy of the travel-time corrections. We then use the declustered set of calibration points and Bayesian kriging to form continuous travel-time correction surfaces for each station of the test network. The effectiveness of travel-time correction surfaces is evaluated by locating, with and without corrections, a subset of the 1991 Racha earthquake sequence (Caucasus Mountains), for which we have accurate locations that were independently determined with a dense local network. When no travel-time correction is applied, the mean horizontal distance between the local and test network locations is 42 km, and there is a distinct bias in sparse-network locations toward the north-northwest. The mean difference between local and sparse network locations is cut to 13 km when corrections are applied, and the bias in location is significantly reduced. When calibration events in the Racha vicinity are not used to make the correction surfaces, there is still a significant improvement in location, with mean mislocations of 15 km. When corrections are not applied, only one of the locally determined locations lies within the associated 90% coverage ellipse determined with the test (sparse) network. However, by using travel-time corrections and estimates of model uncertainty determined using kriging, representative error ellipses are obtained. This study demonstrates that kriging correction surfaces based on global-network-constrained calibration events can improve the ability to accurately locate lower magnitude events while providing representative coverage ellipses.

Those regions close to the core-mantle boundary thought to contain partial melt have a velocity decrement ratio (relative change in shear velocity over relative change of compressional velocity) of about 3. Arguments based on effective medium theories have been given to show that such high values of this ratio are predicted for partial melt systems. The present work confirms the value of 3 near the core-mantle boundary. It is shown, furthermore, that this velocity decrement ratio can be estimated without detailed knowledge of, or assumptions about, the microstructure of the partial melt system by using Gassmann's equation of poroelasticity together with some reasonable assumptions about the change (or lack of change) of the density and bulk modulus for lower mantle pressure and temperature conditions.

AN - 72472404; 11152564 AB - There are two major apurinic/apyrimidinic (AP) endonuclease/3'-diesterase families designated after the Escherichia coli proteins exonuclease III (ExoIII) and endonuclease IV (EndoIV). These repair proteins function to excise mutagenic and cytotoxic AP sites or 3'-phosphate/phosphoglycolate groups from DNA. In mammals, the predominant repair endonuclease is Ape1, a homolog of ExoIII, whereas a mammalian homolog to EndoIV has not been identified to date. We have identified a human protein termed Ape2 that represents a subclass of the ExoIII family (exhibiting highest similarity to the Saccharomyces cerevisiae ETH1/APN2 gene product) and maintains many of the essential functional residues of the ExoIII-like proteins. The human protein is 518 amino acids with a predicted molecular mass of 57.3 kDa and a pI of 8.65. Unlike Ape1, this protein exhibited only weak ability to complement the repair defects of AP endonuclease/3'-repair-defective bacteria and yeast. Similarly, a weak, but specific, DNA-binding and incision activity for abasic site-containing substrates was observed with partially purified Ape2 protein. APE2 is located on the X chromosome at position p11.21 and consists of six exons. The transcript for APE2 is ubiquitously expressed, suggesting an important function for the encoded protein. An Ape2 green fluorescent fusion protein localized predominantly to the nucleus of HeLa cells, indicating a nuclear function; this localization was dependent on the C-terminal domain. We discuss our results in the context of the evolutionary conservation of the AP endonuclease families and their divergent activities and biological contributions.

AN - 70929845; 10692228 AB - To test the hypothesis that the sulfotransferase gene plays a role in the phase II bioactivation of PhIP, a heterocyclic amine found in cooked meats, we transfected the UV5P3 cell line with cDNA plasmids of human aryl sulfotransferases (HAST1 and HAST3). UV5P3 is a nucleotide excision repair-deficient and P4501A2-expressing CHO cell line that we have previously developed. Functionally transformed clones were identified by the differential cytotoxicity (DC) assay that used PhIP as the cytotoxic agent. Two clones designated 5P3H1 and 5P3H3, expressing HAST1 and HAST3, respectively, were chosen for further characterization. Correct fragment sizes of the sulfotransferase cDNAs were identified in both cell lines by polymerase chain reaction. Immunoblot analysis confirmed the expression of the sulfotransferase proteins. The addition of the sulfotransferase inhibitor DCNP decreased the cytotoxic effects of PhIP in a dose-dependent manner. The increase in cell growth was 6. 5-fold for 5P3H1 and 2.4-fold for 5P3H3, relative to values obtained without DCNP. Based on D(50) values, the dose that reduced the survival to 50% relative to untreated controls, the cytotoxic effect of PhIP was increased threefold for 5P3H1 and 1.87-fold for 5P3H3 cell lines over the parental UV5P3 line. There was also a small increase in the mutation response at the aprt locus. These newly established 5P3H1 and 5P3H3 sulfotransferase-expressing cells provide valuable mechanistic information of the bioactivation of PhIP and related compounds. Environ. Mol.

In that war, Iraq intervened on the Syrian front with an armored division, other supporting units, & over 100 aircraft. This intervention, which occurred despite severe political & military difficulties, was larger than any previous Iraqi contribution to the anti-Israeli struggle. Baghdad later asserted that Iraqi forces had saved Damascus from possible Israeli occupation, & these claims have been widely repeated by a variety of authors of different nationalities with various degrees of agreement or skepticism. Nevertheless, Iraqi claims to have saved Damascus from Israeli capture are false since the Israelis did not view the seizure of the city as important to their strategy for victory. Rather, the Iraqi presence on the Golan Heights was useful to the Arab war effort as one of many factors helping to delay the Israeli advance & prevent some important Syrian targets from being placed within artillery range of the Israeli force. Iraqi military shortcomings were well highlighted in this conflict, & many were repeated in the early stages of the war with Iran. Adapted from the source document.

Despite the presence of numerous Fe-, Ni-, and Pt-rich spherules in the ferromanganese crusts studied, ratios of the platinum group elements (PGE) in the ferromanganese material from one sample indicate that Pt is greatly enriched compared to the other PGE and slightly enriched (about two times) with respect to seawater ratios. Osmium isotopic ratios also indicate a nonchondritic source for the PGE. Much of the crust Pt and Ir correlates with Fe-rich layers. Results of seawater-ferromanganese oxide adsorption experiments using (super 191) Pt and (super 192) Ir suggest that Pt is preferentially scavenged by FeOOH when compared to Ir, suggesting a seawater source for the enrichment. Platinum, Fe, Mn, Ni, and Co all co-vary within the Pt-rich zone in stratigraphic transect 1 of this crust. The more detailed transect 2 results differ somewhat from those of transect 1. These data are compared with Pt and Ir data obtained by laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS) analyses at approximately 1-mm intervals. Redox-sensitive elements such as Fe, Mn, Co, Cr, the derivative Ce and Eu anomalies, and Sm/Yb ratios from transect 2, when compared with the Pt profiles, suggest that localized redox conditions associated with either O (sub 2) minimum zone processes or with the formation of carbonate fluorapatite (CFA) are responsible for the Pt enrichments. Analyses of two other crust samples from the same seamount and several other ferromanganese crusts from other areas of the Pacific suggest that the PGE enrichment is more closely tied to the formation of the CFA than to O (sub 2) minimum zone processes, carbonate ion variations in the water column, or cosmogenic sources.

Analysis of aquifer (channel deposit) connectivity, simulation of complex response to a pumping test, and assessment of effective hydraulic conductivity of the system led to a connected network paradigm for the system and exposed potential shortcomings of more conventional paradigms of subsurface heterogeneity. Typical of many alluvial fan deposits, this system contains a significant volume fraction ( approximately 60%) of fine-grained materials, and the primary aquifer units, localized channel sand and gravel deposits, compose only 18% of the system. Although conventional hydrostratigraphic analysis would suggest that the channel facies are not extensively interconnected, in this stochastic model most (>70%) of the channel cells compose one channel domain that fully interconnects, or percolates, in all three dimensions. Simulation of complex response in multiple observation wells to a 24-hr pumping test demonstrated plausibility of the hydrostratigraphic model and connected network paradigm while providing insights into hydraulic processes in a complex aquifer network. Simulated time-drawdown responses at observation well locations were most sensitive to hydraulic properties of the fine-grained, nonaquifer materials. Contrary to conventional leaky aquifer paradigms based on layer-cake models, decreasing K of the aquitard (flood plain) facies increased, rather than decreased, drawdowns at observation points located in aquifer zones that would commonly be assumed to be separate from the channel stratum being pumped. A lowered flood plain K focuses and extends drawdown into more distal reaches of the channel network. Because of the extensive connectivity of channel sediments, effective hydraulic conductivity parallel to the channels (dip direction), k' (sub y) is merely the arithmetic mean. K' (sub x) (strike direction) and K' (sub z) (vertical direction) are both controlled by more complex hydraulics due to circuitous connectivity transverse to the channel orientations. Channel connectivity and K' (sub z) are sensitive to spatial cross correlation between channel and levee facies in the geostatistical spatial model, demonstrating that facies juxtapositional tendencies can be hydrologically significant.

However, limited remote sensing has been attempted at this caldera. Our group is applying spectroscopic mapping with traditional geological data to refine current geological models and maps, to assess the strengths and limitations of using biological phenomena to model and map geological processes and structures, and to prepare baseline datasets for volcano monitoring efforts via space-borne instruments. On September 7, 1999, imagery of the caldera was flown using Integrated Spectronic's HyMap hyperspectral imager. These images are being analyzed to gain a better understanding of the hydrothermal system and to refine present flow models. This includes delineating zones of discharge and their general geochemistry and temperatures as resolved by hydrothermal mineral assemblage mapping. We present an example of structural mapping in the western caldera which elucidates how this region of crust is accommodating such perturbations as magma chambers, dike intrusions, and regional stress as well as aspects of the transport of hydrothermal fluids, gasses, and magma along such structures. We also present data on the sizes and locations of the CO (sub 2) -induced tree-kills at Mammoth Mt., specifically near Horseshoe Lake. JF - Proceedings of the ...

Recent studies suggest that the ice sheet is still adjusting to postglacial changes in climate and sea level, with active retreat of the grounding line in the Ross and Amundsen Sea sectors [1-4]. The thinning history of the ice sheet east of the Ross Sea can be determined directly by dating recessional moraine deposits in the coastal mountains of Marie Byrd Land. Scattered, fresh ground moraine extends from the present ice level to the highest summits in the Sarnoff, Denfeld and Fosdick Mtns. In addition, ice flow crossed these ranges obliquely, suggesting that they were overrun by thick ice during the glacial maximum. The direction of ice flow and provenance of erratics (indigenous to the Ford Ranges) suggest a high divide or dome existed to the SSE during the glacial maximum, maintaining isolation of the region from the Ross Sea. Preliminary exposure ages of approximately 3500 yr for erratics at 400-500 m elevation in the Sarnoff Mtns suggest that deglaciation was still in progress, with outlet glaciers roughly 400 m above their present levels near the coast, in the late Holocene. These dates contribute to a growing body of evidence that recession of the West Antarctic ice sheet lagged that of all other late Pleistocene ice sheets, and may still be in progress. At the meeting we will present a more comprehensive deglaciation chronology based on exposure age-altitude transects and explore the implications of these results for past and future sea-level change.

Several studies of (super 10) Be in Chinese loess have been made to reconstruct the history of climate and weathering on the Loess Plateau. Nevertheless, (super 10) Be geochemical behavior, especially its mobility in wind-blown dust sequences during weathering, needs to be more fully understood for its application in sedimentology, pedology, paleoclimatology, and chronology. In this paper, measurements of (super 10) Be, (super 9) Be, and major elements in different grain size fractions, in selected chemically leached fractions and in bulk samples from some sections of loess-paleosols and red clay in the Loess Plateau were conducted using AMS (accelerator mass spectrometer), XRF, and ICP-MS. The data provide a clear picture of geochemistry of (super 10) Be in dust deposits. Similar to the (super 9) Be distribution pattern over different grain size fractions, (super 10) Be concentration increases with the decrease in particle size of the loess and paleosol samples. The amount of (super 10) Be in the < 4mm grain size fraction is more than 60% of the total, indicating that most of the (super 10) Be is carried by clay minerals. Since dust sediments have an appreciable endowment of (super 10) Be from source regions, concentrations of (super 10) Be in loess, paleosols and red clay would depend on dust grain size. Comparing (super 10) Be concentration fluctuations with changes in (super 9) Be concentration, grain size proxy of Si/Al ratio, and weathering index of Na/Al ratio through loess-paleosol profiles and the red clay section, we conclude that (super 10) Be is chemically immobile in dust deposition-weathering sequences.

Natural variation in hydraulic conductivity has long been known to accelerate dilution and spreading in aqueous contaminant plumes; associated variation in reactive mineral abundance or specific sorption capacity can also impact the perceived rates of migration and dilution. Here, we will present a series of data analyses and example simulations that show the existence and impacts of chemical heterogeneity on the mobility of various types of reactive contaminants. In short, the results indicate that identification of reactive properties of lab scale geologic samples may misrepresent what is happening at the field scale. These types of results are being used to develop plans for more specific data gathering efforts and to suggest better approaches for understanding and characterizing the nature of reactive transport at larger scales of observation.

Important in these simulations is the representation of porosity/permeability functions that directly link dissolution/precipitation effects to mass and heat transfer. We have developed a computer code (NUFT-Chem) that runs on massively parallel platforms and which fully couples these processes. We report the results of high resolution, three dimensional simulations in a 12 component, 40 mineral system involving thermal perturbations in the unsaturated zone. The geometry and thermal history represented, closely correspond to that anticipated for a high level nuclear waste repository. Approximately 100 waste packages, each with a discrete thermal output, was represented. A total rock volume of approximately 10 cubic kilometers was considered, with spatial resolution varying from 10 cms. to 10s of meters. Heat deposited by high level nuclear waste instigates complex fluid and gas movement which leads to mineral dissolution and precipitation along hydrothermal flow pathways. The resulting time dependent change in mineralogy, porosity, permeability, matrix and fracture saturation, fluid chemistry and temperature in the vicinity of waste emplacement drifts, was captured. The results show dramatic and complex evolution of pore and fracture water compositions shortly after heat is deposited by the waste packages. However, for short term (100s of years) monitoring only a few chemical variables show evolutionary changes sufficient to be detected by in situ measurement. The location and magnitude of specific changes are strongly correlated to location in the repository (edge vs center, for example) and local heat output of the waste packages. The results provide a striking example of the importance of considering the three dimensional properties of a complex geological system at high resolution, in order to capture its response to thermal perturbation.

Technological innovations in instrumentation, for example, have allowed geochemists to monitor various geochemical processes like mineral dissolution and precipitation and ion sorption at the microscopic scale. The improved understanding of the underlying mechanisms of geochemical processes has given new insights into the relative importance of a number of geochemical parameters, for example, the effect of competing ion concentrations and multiple binding sites on ion sorption and mineral dissolution/precipitation. The new understanding of the importance of various parameters on geochemical processes, however, has mostly not made its way into hydrologic transport models, despite the fact that many of these processes affect contaminant mobility. "Classical" transport models typically rely on constant distribution coefficients or "Kds" to describe contaminant mobility. The constant Kds are often used to describe the role of geochemical processes as diverse as mineral precipitation and dissolution, multicomponent ion exchange, and surface complexation. In many surface and subsurface environments, however, hydrologic and geochemical processes result in sufficiently large changes in environmental conditions that the approximation of a constant Kd becomes invalid. An example involving Cs migration in the vadose zone populated by multiple exchange sites and variable concentrations of competing cations is given which illustrates the potential problems with the assumption of constant distribution coefficients.

However, whether surface rupture during these earthquakes crossed the Hersek Peninsula or occurred offshore in the Marmara Sea remains a contested issue. We analyzed aerial photo stereopairs, conducted detailed field mapping following the August 17, 1999 Kocaeli earthquake, and excavated reconnaissance paleoseismic trenches to delineate the location of the Yalova segment and to determine whether significant slip occurred on this structure during the Kocaeli earthquake. We observed minor offsets and cracking (<5 cm) across the Hersek Peninsula that we infer were induced by sympathetic slip on the Yalova segment due to stress transfer during the Kocaeli earthquake. However, no significant surface fault rupture was observed. Numerous fault-related geomorphic lineaments that cross the Hersek Peninsula and evidence for late Holocene deformation in paleoseismic trenches across one of these lineaments supported the conclusion that the Yalova segment crosses the Hersek Peninsula. Stratigraphic relationships in four trenches excavated across the Yalova segment show that 290-480 ka marine terrace deposits have been tectonically tilted up to 75 degrees toward the south. Furthermore, a Byzantine pipeline (1.6-2.0 ka) exposed in the east trench may have been tilted up to 3 degrees toward the south. Archeological features in several trench exposures obscured possible fault-related features necessary for determining a late Holocene earthquake history for the site. Future trenching studies should investigate probable fault-related geomorphic lineaments that cross the Hersek Peninsula. Future paleoseismic studies of this nature combined with marsh stratigraphic studies may provide additional data to assess the magnitude and timing of the most recent earthquake and estimate a late Holocene geologic slip rate for the Yalova segment.

Two main aquifers are present: A seriously over-exploited upper aquifer, and a deeper H2S-rich confined aquifer. At present the upper aquifer is the main source of water to supply Puebla City. However, because of heavy demand for groundwater, the confined aquifer is being considered as an additional source. Our study attempts to determine: 1) the recharge area for the aquifers and 2) whether there is a magmatic component to the groundwater in either aquifer. Recharge sources have not been firmly established for either aquifer. Possible recharge areas for both are from the west (volcanos Popocatepetl and Ixtlaccihuatl) and from the east (volcano La Malinche). Past research has suggested that recharge (particularly for the confined aquifer) occurs at the north of the Valley of Puebla and that groundwater movement is restricted by lacustrine sediments. Oxygen and deuterium isotope determinations indicate that groundwater of the upper aquifer varies widely (delta (super 18) O = -9.4 to -12; delta D = -72 to -90 per mil) and is correlated roughly with elevation. Water of the lower, confined aquifer comes from an intermediate elevation as indicated by tightly clustered isotopic values (average delta (super 18) O = -10.7; delta D = -76 per mil). This suggests that the confined groundwater is recharged in the north of the Valley. Water of some of the wells being pumped by the City of Puebla are characterized by high alkalinity and high gas content but low nitrate, indicating a possible magmatic component. H2S in the confined aquifer could also be attributed to magmatism. We have analyzed 36Cl in a number of samples. Results to-date indicate that some water contains a clear atmospheric component. Water-rock interaction and magmatism could explain other chlorine data.

Failure of these glacial dams produced some of the largest known lake-outburst floods, which created spectacular erosional and depositional landforms and sporadically supplied large amounts of fresh water to the Arctic Ocean via the Ob and Yenesei Rivers. The best-known of these floods issued from the Kuray and Chuya Basins in the Russian Altai Mountains. The stratigraphy and sedimentology of flood deposits in this region are well characterized, but their chronology is known only from scattered thermoluminescence and radiocarbon ages on pre- and post-flood sediments. In order to directly date flood-related landforms without relying on bracketing ages, we measured concentrations of the in-situ-produced cosmogenic isotope (super 10) Be in quartz from flood-transported clasts in giant gravel dunes located in the valleys of the Katun and Chuya Rivers. We measured (super 10) Be abundance in both surface and subsurface samples (e.g., Anderson et al., 1996; Repka et al., 1997) to determine the contribution of inherited 10Be to the total inventory. Initial measurements indicate that inherited exposure of gravel clasts is minimal, and the floods occurred between approximately 17,000 and 36,000 years B.P., which agrees with previously determined limiting ages of 6,000 and approximately 30,000 years B.P. This further suggests that at least one extensive alpine glaciation of this region of Central Asia was approximately coeval with the last glacial maximum elsewhere. In light of reports of other megaflood deposits scattered across southern Russia, the possibility of widespread large meltwater floods in Central Asia during OIS 2 may be significant in understanding glacial maximum conditions in the Arctic Ocean.

Identification of optimal injection sites, however, requires quantifying--as a function of physical and chemical formation properties--the relative effectiveness of interdependent CO (sub 2) migration and sequestration processes. These functional sensitivities reveal geochemical, hydrologic, and structural constraints on maximizing sequestration effectiveness, which can be used to identify target reservoirs most likely to provide optimal storage capacity and isolation security. We are integrating kinetically-controlled reactive-transport and multiphase-flow simulators (GIMRT, NUFT), supporting geochemical software and thermodynamic/kinetic databases (SUPCRT92, GEMBOCHS), and recent equation-of-state and viscosity formulations for CO (sub 2) (Span and Wagner, 1996; Fenghour et al., 1998) to develop a unique modeling capability for identifying optimal target formations in this manner. Confidence in this modeling approach hinges on success in simulating the observed behavior of natural and experimental systems. Hence, our initial efforts involve simulation of CO (sub 2) injection at the unique Sleipner facility (North Sea), where properties of the target aquifer and its bounding cap rock are well constrained, and location of the migrating CO (sub 2) plume after three years of injection has been established. Preliminary modeling results suggest that local permeability structure of the target formation controls the path of CO (sub 2) movement by all migration processes (immiscible displacement, gravity segregation, and viscous fingering) as well as the potential effectiveness of all sequestration processes (structural, solubility, and mineral trapping). For typical sandstone-aquifer compositions, at least 90% of the injected CO (sub 2) migrates as an immiscible plume; hence, potential structural trapping represents the dominant sequestration mechanism. The presence of intra-aquifer shale units retards vertical and promotes horizontal CO (sub 2) migration, thus expanding the volumetric extent of CO (sub 2) -aquifer interaction, and thereby increasing the effectiveness of solubility trapping and potential effectiveness of mineral trapping. The relative impermeability of inter-bedded and cap-rock shales, where Fe/Mg-bearing clay minerals are abundant, may be enhanced by carbonate precipitation, thus improving cap-rock integrity--the most important constraint on long-term isolation performance. In fact, optimal performance may perhaps be achieved sans contributions from any sequestration process within a very extensive aquifer capped by a virtually impermeable seal.

In the absence of scarps, this fold, or pressure ridge, is the only positive relief feature that indicates strike-slip activity on the Carrara fault, a northwest-trending fault situated approximately 1 km east of the waste facility. Current geophysical data suggests the fold originated by transpression between the Carrara and Stateline faults, or by a change in strike (stepover or restraining bend) along southern Carrara fault segments. To determine the approximate age of initial folding, six surface samples, each containing 15-20 amalgamated clasts, were collected from two localities on the fold crest and dated by Terrestrial Cosmogenic Nuclide (TCN) methods. The six exposure ages range from 239-275 ka, with a mean age of the fold crest calculated to be 255+ or -13 ka. This date agrees well with the estimated age of the stage III CaCO (sub 3) soil horizon that has accumulated below the surface of the fold. Assuming the surface isolation is due to compression and uplift, and not fluvial downcutting, folding and movement on the Carrara fault occurred during the Middle Pleistocene about 200-300 ka. The eastern limb of the fold is now breached by a northwest-trending valley, which we suggest has a tectonic, not fluvial, origin. Thus, the character of strike-slip movement on the Carrara fault appears to have changed from compression to extension, probably some time during the early Late Pleistocene. We interpret this valley to be a graben, the northern extension of which appears to have downdropped the distal ends of some Bare Mountain fans. Although no fault scarps are present, this circumstantial geomorphic evidence, in conjunction with the TCN-dated fold, suggests that deformation along the Carrara fault continued into the Late Pleistocene.

The sub-meter vertical resolution of these new systems allows estimation of Holocene fault displacements, lake level changes and large-scale sedimentation patterns. In the summer of 1999, we conducted a "Proof-of-Concept" high resolution sub-bottom survey at Lake Tahoe to demonstrate the usefulness of this emerging technology within an alpine lake environment. Due to ship availability, we were restricted to using the SUBSCAN CHIRP in "float-mode", which limited our imaging capability to 100 meters or less. Nonetheless, we identified a significant accommodation zone on the shallow shelf near Tahoe City, representing a major zone of deformation between two fault-blocks. An unexpected result of our cruise, with linkages to climate studies, was the discovery of a truncated prograding delta that records a significantly lower lake level ( approximately 60 feet). This observation, coupled with a beautiful image of a approximately 50 foot deep in-filled channel at the Tahoe City Dam, suggests lake level fluctuations associated with channel erosion and lake downdraw--not drought, and may be tectonic (possible tsunami/seiche wave) in origin. Lastly, regions of stratigraphic wipe-out in images near the steepened slopes of the west-shore indicate the presence of gas at depth, which may play a significant role in slope failure. We have been funded by NSF/ONR to conduct 8 additional days worth of data acquisition (August 2000), half in "deep-tow" mode, allowing investigation of the major bounding faults within the basin. Reconnaissance profiles will be collected near a few tributaries to test whether this system can be used to track fine-scale, historical sedimentation patterns within the lake.

Within such high mountain environments, erosional and depositional landforms provide evidence for the nature, rates and magnitudes of denudation, sediment transfer and deposition. We studied strath terraces, moraines, paraglacial fans and outwash terraces in the Khumbu Himal south of Mount Everest using sedimentological and geomorphic techniques, field mapping and numerical dating (Be-10 and Al-26 cosmogenic radionuclide, optically stimulated luminescence and radiocarbon). Our results have allowed us to quantify rates of landscape evolution in what is the highest glaciation region of the world. Our data shows that the rate of denudation in the glaciated catchments of the Khumbu Himal is on the order several millimeters per annum when averaged throughout the Late Quaternary. However, comparison of strath, outwash terrace, and fan ages with moraine ages that record the timing of glaciation in the Khumbu Himal indicates that denudational processes and sedimentation were more rapid during the short periods of time when glaciers were retreating. This suggests that climatic oscillations resulting in deglaciation provide the main driving force in controlling rates of denudation and sediment transfer in Himalayan and other high mountain landscapes. We therefore stress that great care must be taken when using contemporary rates of denudation in areas where glaciers are retreating to estimate rates of denudation over geologic timescales for modeling the landscape evolution of high mountains.

Washington in New Hampshire and Mt. Katahdin in Maine is much higher (1.5 to 8 times) than expected had the peaks been covered by active, erosive ice during the last glacial maximum (LGM) about 21. 5 ky calibrated 14-C years ago. Samples from the summits of Mt. Washington have 10-Be model exposure ages of 124 and 22 ky; one sample from Mt. Katahdin has a model age of 25 ky (assuming production rates of Nishiizumi et al., 1989). In contrast, other near-summit samples (n = 3) and boulders (n = 5) from the Basin Ponds moraine on Mt. Katahdin have an average age of 12.7+ or -0.7 ky. A single boulder from the well-dated Pineo Ridge moraine complex in coastal Maine (13.2 to 14.0 cal 14-C ky BP) can be used to estimate integrated 10-Be and 26-Al production rates of 5.8 to 6.1 and 38.3 to 40.7 atoms/(g*yr) at 60 m asl and 44 degrees N. The mountain-top samples are consistent with two different scenarios, both of which have significant implications for understanding the spatial and temporal pattern of glaciation and glacial erosion in New England: 1) LGM Laurentide ice was thinner than previously supposed leaving the top of Mt Katahdin exposed since early stage 2 and parts of Mt. Washington's summit exposed since stage 6, 2) both summits were covered by glacial ice during the LGM, but the ice was thin enough to be frozen to its bed. Thus, the cold-based ice was unable to erode much rock, allowing nuclides to be inherited from prior periods of exposure. In either case, Laurentide ice in New England during the LGM was thinner than previously believed, consistent with low basal shear stresses and/or the presence of active ice streams.

Just as elusive as the runout mechanism is the age of the landslide.The age of the Blackhawk landslide has been estimated by radiocarbon at >17.4 + or - 0.6 ka (Stout, 1975). The date, measured on gastropod and pelecypod shells, picked from a calcareous mudstone bed in a pond on the landslide surface, has two potential problems; the pond from which the fossils were extracted is younger than the landslide and thus any age represents a minimum limit; the aquatic organisms may have incorporated "dead" carbon from the pond water because the pond sits in carbonate rock. We sampled gneiss boulders to date the landslide using cosmogenic 10-Be, three boulders (>1 m) from the top of a lateral ridge (BH-4, BH-5, and BH-6) and one boulder (>1.5 m) from the landslide-facing slope 3 meters below the ridge (BH-3). The 10-Be concentration of BH-3 is 3.48+ or -0.15X10 (super 5) atoms/g; concentrations in BH-4, 5, and 6 range from 6.4+ or -0.45X10 (super 4) to 9.3+ or -0.36X10 (super 4) atoms/g. Exposure age (assuming a sea level, high latitude production rate of 6.03 atoms/(g y)) for BH-3 is 24.2+ or -4.8 ka and exposure ages for BH-4, 5, and 6 average 5.7+ or -1.1 ka. Two scenarios may explain these disparate ages. Either, all samples have been exposed fully since landsliding about 5.7 ka and BH-3 had exposure history prior to landsliding, or the landslide is 24.2 ka and BH-4, 5, and 6 were covered by 3.5 to 5.5 m of sediment that has eroded away exposing the boulders at a rate averaging 19+ or -4 cm/ka. A combination of these two endmembers is also possible. Only further sampling and 10-Be analysis will better estimate the age of the Blackhawk landslide.

As their absolute ages are unknown due to a lack of suitable material for U/Th dating, the terraces do not live up to their potential to constrain uplift rates, examine rates of landscape evolution, and constrain pedogenic rates. The first terrace has been variously correlated with isotope stages 5a, 5c and 5e; estimated uplift rates range between 0.21-0.45 mm/yr. On a stable surface the production of cosmogenic nuclides (CRNs) acts as a clock, yielding the age of the surface. The Santa Cruz terraces are capped by 1-4 m of regressive beach sands; therefore both pre-depositional inheritance and post-depositional pedogenic effects, including bioturbation, must be treated in any sampling and interpretation strategy. The expected CRN concentration profile should be homogenized within the bioturbated layer and exponentially decrease below, asymptotically approaching the initial concentration of the capping beach sands. Sampling sites were selected on large flat areas showing no evidence of either colluviation or erosion. The measured CRN depth profiles in the first, second, fourth, and fifth terraces have mutually consistent 10Be and 26Al concentrations and display the correct relative age sequence, with each higher terrace exhibiting higher CRN concentrations. The top few tens of centimeters of each profile display homogenization, presumably reflecting bioturbation. Each profile is offset differently, reflecting variations in inherited CRN concentrations. Assuming stable surfaces, the best-fit model ages are: 47 ka for the first terrace, 87 ka for the second, 133 ka for the fourth and 230 ka for the fifth. These roughly correlate with the sealevel highstand isotope stages 3 (56 ka), 5a (84 ka), 5e (125 ka) and 7 (212 ka). Modeling shows that several meters of erosion would be required to match previous age estimates for the terraces, which is unlikely given their location. These age assignments imply a roughly steady uplift rate of 1.15 mm/yr, two to four times greater than inferred from previous correlations.

An understanding of the groundwater system, and its development over time, is therefore essential in understanding the total hydrocarbon system of the region. We applied the I-129 (half-life 15.7 Ma) and Cl-36 (half-life 0.3 Ma) systems to investigate the paleohydrology of the San Juan Basin; in particular, the extent of recharge and water movement within the Fruitland coals. The presence of large anthropogenic I-129 and Cl-36 signals in surface waters allows the potential detection of even minor contributions from recent meteoric input. I-129 analyses were carried out for 71 production wells within the Fruitland Formation, and Cl-36 was analyzed for 19 wells. This study represents the most detailed study of I-129 in a single sedimentary basin to date, permitting a high-resolution view of variations caused by past fluid circulation. Preliminary results indicate that the formation waters are remarkably well preserved, yielding minimum iodine ages as old as 57 Ma. Dilution of iodine by paleohydrologic input is apparent both in the iodine concentrations as well as the stable isotope record of the water in portions of the basin. The majority of the basin has a Cl-isotopic composition that approaches the limits of detection though accelerator mass spectrometry and requires that infiltration of surface water has not occurred in over 2 million years. Recent meteoric contributions within the Fruitland are restricted to outcrops at the margins of the basin.

Loss of noble gases at groundwater flow barriers, along flow paths from recharge to discharge areas, is the likely cause of this temperature increase. Emplacement of low permeability rock into high permeability aquifer rock and the presence of low permeability shear zones along flow paths reduce aquifer thickness from thousands to tens of meters. At these flow barriers, noble gases are likely stripped from the groundwater by gas bubble formation because of greatly reduced hydrostatic pressure. Noble gas solubilities are lower at flow barriers than in recharge areas because water-table temperatures are about 10 to 20 C higher near barriers than in recharge areas. Molecular diffusion would not be an important noble gas removal process for these groundwaters because concentration gradients are small.

The MSTHM accounts for processes occurring at a scale of a few tens of centimeters around individual waste packages (WPs) and emplacement drifts and also on behavior at the scale of the mountain. The MSTHM calculates TH variables that are important to the performance of various engineered components in the drifts, including the WPs, the waste form, and the drip shields that overlie the WPs. The TH variables that are calculated in the drifts and near-field host rock throughout the repository area include temperature, relative humidity, liquid saturation, gas-phase air-mass fraction, gas-phase pressure, capillary pressure, evaporation rate, liquid-phase flux, gas-phase (air and vapor) flux, and the lateral extent of the boiling-point isotherm. The MSTHM captures the key factors (and their variability across the repository) affecting the distribution of TH conditions in the drifts and near-field host rock, including: (1) infiltration flux, (2) host-rock thermal conductivity, (3) host-rock capillary properties, (4) overburden thickness, (5) edge-cooling effect, and (6) WP heat generation. The uncertainty associated with the first three factors needs to be assessed, particularly for the first factor. Higher infiltration fluxes decrease the magnitude of the following performance measures: extent of boiling (and dryout) in the host rock, peak drift-wall and WP temperatures, and duration of relative humidity RH reduction in the drifts. Coupled thermohydrologic-geochemical-geomechanical (THCM) processes also introduce uncertainties arising from potential changes to hydrologic properties; such changes can be addressed using the MSTHM.

Oxygen and hydrogen stable isotope results reveal that cool season precipitation (mostly snowfall) is isotopically similar to nearby mountain springs, implying that most recharge is snowmelt-derived. However, whereas the winter precipitation samples plot on the global meteoric water line (GMWL), the mountain spring waters are shifted to the right of the line, with an average deuterium excess value of +4. This suggests a kinetic isotope enrichment process during recharge. Bulk snow core samples collected from 28 locations in central Nevada at the time of peak accumulation (March) are also shifted to the right of the GMWL, with an average deuterium excess value of +5. Individual snow cores show physical evidence of snow metamorphism accompanied by heavy isotope enrichments, particularly near the base of the snowpack. These results suggest that kinetic isotope effects related to vapor loss during snow metamorphism cause isotopic enrichments in the snowpack that are not observed when the snowfall is simply accumulated in a precipitation gauge. This process may be a key factor governing the widely observed shift off the GMWL in Nevada groundwaters. This work was performed under the auspices of the U. S. Department of Energy by Lawrence Livermore National Laboratory under contract number W-7405-Eng-48.

To estimate the contribution from subsurface 36Cl production, and from water-rock interaction, contrasting host rocks (one carbonate and one volcanic) were water leached and 36Cl/Cl ratios were measured. In addition, seasonal meteoric water and recently recharged spring waters were analyzed in order to constrain the initial 36Cl/Cl ratio. Preliminary results suggest that groundwater from the Pahranagut Valley (White River Basin) has a 36Cl/Cl ratio that is close to the value for meteoric input (approximately 7E-13). Evaporation of agricultural waters in this eastern valley increases the Cl concentration without changing the 36Cl/Cl ratio. Waters derived from the regional carbonate aquifer, Tertiary volcanic aquifers, and alluvial aquifers in Frenchman and Yucca Flat (Nevada Test Site) show distinct Cl concentrations and 36Cl/Cl signatures. These results are consistent with hydrogeologic data that suggests slow interaction between these different aquifers due to low permeability in the volcanic units. In groundwater from the regional carbonate aquifer, chloride is primarily derived from water-rock interaction with the carbonates. These waters have a relatively high Cl concentration and a low 36Cl/Cl ratio (1.5E-13). Higher 36Cl/Cl ratios (4-5E-13) are observed in the Ash Meadows springs discharge area where there has been mixing with a less chemically evolved water with a greater contribution from cosmogenic 36Cl.

This approach accounts for processes occurring at a scale of a few tens of centimeters around individual waste packages (WPs) and emplacement drifts and also on behavior at the scale of the mountain. The MSTHM captures how WP-to-WP heating variability influences TH conditions along drifts. It also captures the natural-system variability consistent with what we know from site characterization. The broad range in repository performance measures predicted by this approach underscores the limitations of models based on average repository parameters. There are a large number of ways in which engineering design variables (e.g., drift spacing) can be combined and there will always be some uncertainty about natural-system factors (e.g., infiltration fluxes), but TH behavior to first order can be readily characterized by only a few performance attributes. These are: whether boiling occurs in the host rock, whether boiling zones around individual drifts coalesce, the degree of variability of TH conditions along drifts, and the relative humidity RH gradient between the drift wall and the surfaces of engineered components within the drifts. Repository design involves choices between conflicting thermal-management goals. For example, the addition of backfill in the drifts trades higher WP temperatures for increases in the duration of relatively dry WP conditions (i.e., lower RH and delayed onset of seepage). Sub-boiling designs (without backfill) trade the potential reduction of uncertainty that arises from the elimination of boiling for wetter in-drift conditions (i.e., higher RH and earlier onset of seepage).

Bull Lake moraines along upper Boulder Creek have minimum average 10Be and 26Al ages of 101+ or -21 ka and 122+ or -26 ka and Pinedale moraines have average model ages of 16.9+ or -3.5 and 17.5+ or -3.6 ka. Isolated terrace remnants 20 to 15 m above grade give a model age of 130+ or -27.5 ka. More extensive fill terraces 15 to 4 m above grade have average model ages from approximately 30 to 10.5 ka (early to late Pinedale). Low terraces and fans built from tributary catchments show that Boulder Creek has been within 4 m of grade throughout Holocene time. Inset, closely spaced Pinedale-age terraces record multiple pulses of local aggradation and incision 5 to 20 km downstream from Pinedale moraines, implying that glacial events controlled terrace formation. Relative soil development and sparse radiometric ages suggest that the Louviers, Broadway and Piney Creek Alluviums downstream on the High Plains correlate with the three groups of terraces along Boulder Creek. Louviers and Broadway surfaces are only 7 and 4 m, respectively, above grade, indicating downstream convergence of terrace profiles, and slower net incision in the High Plains in late Pleistocene time. Since approximately 600 ka, net incision rates on the High Plains near Boulder Creek have been approximately 0.04 m/ka, whereas rates in Boulder Canyon have averaged approximately 0.15 m/ka since about 130 ka. Extrapolating late Pleistocene rates to middle Pliocene time gives 375 m of net incision in Boulder Canyon, deeper than the modern canyon. Downcutting rates along Boulder Canyon must have increased since early Pleistocene time, perhaps as bedrock knickpoints migrated upstream in response to increases in snowmelt discharge.

Chlorofluorocarbons (CFCs), tritium/He-3 and stable isotopes were measured in ten springs during two sampling periods, August 1997 and November 1999. Spring water ages were calculated from the CFC measurements and were found to vary throughout the basin from ten to forty years and were in good agreement between the two sampling times. The CFC ages correlate well with T/He-3 ages but are slightly older. Values of delta 18-O were consistent between the two sampling periods for each spring. An excellent correlation exists between the CFC ages and corresponding delta 18-O for the sampled springs in which older spring waters are more negative than younger spring waters by more than one per mil. Long term changes on the glacial to interglacial scale of the stable isotopic composition of recharging water have been documented in groundwaters and attributed to temperature change and changes in atmospheric circulation patterns. However, changes on the scale of decades as seen in the Sagehen basin have not been previously documented. One possible explanation for this trend in stable isotopic composition is a change in the isotopic composition of precipitation. However, no long term isotopic records exist for the Sierra Nevada precipitation. Additional factors that may affect the stable isotopic composition of recharging groundwater include an increase in the recharge temperature, a change in the proportion of precipitation falling as snow, and/or a change in the source region of major storms.

AN - 51883631; 2004-018384 AB - Late Miocene to Recent extensional faults in the Andes above the Peruvian flat slab (2 degrees S to 15 degrees S) exhibit a marked west-dipping structural asymmetry. A transect across the central Peruvian Andes (at 9 degrees S) shows a series of large-scale, west-dipping normal faults, including the Cordillera Blanca detachment fault and apparent detachments in the Maranon fold and thrust belt. At least two of these faults are deep-seated, with seismicity to >15 km. Major normal faults also dip west in the northern Peruvian Andes (e.g., bounding the Namora, San Marcos and Cajabamba basins) and southern Peruvian Andes (e.g., Cusco to Vilcanota region). Although extension was clearly enhanced by topographic and thermal effects (e.g., emplacement of Cordillera Blanca batholith), these alone do not adequately explain the extent, structural asymmetry and deep-seated nature of major extensional faults in Peru. We suggest that aseismic ridge subduction and flattening of the subducting Nazca slab played a role in driving extension in Peru. Given that horizontal subduction under Peru was driven by subduction of aseismic ridges (Gutscher 2000), we can roughly estimate the timing of slab flattening using the chronology of ridge subduction. Most notably, the Nazca Ridge arrived under the Cordillera Blanca arc (at 9 degrees S) ca. 5 Ma, coincident with both the cessation of arc magmatism and the onset of detachment faulting in this region. Strong spatial and temporal ties thus exist between ridge subduction, arc extinction due to slab flattening, and the initiation of detachment faulting. Here, we propose that west-dipping detachment faults in Peru formed as synthetic Riedel shears linked to horizontal slip along the plate interface. Movement of both the Nazca slab (along basal "Y" shear) and crustal footwall blocks (along synthetic "R" shears) are east directed, with an approximately 20 degrees angle subtending Y and R shears, i.e. kinematics and geometry remarkably similar to that of Riedel shear systems. The model requires that mid-to-upper crustal strain be coupled to the plate interface via a strong lower crust, plausibly the case in Peru given refrigeration of overriding South American lithosphere by flat slab subduction.

The study site, located at the Panola Mountain Research Watershed, Georgia, has developed a granite/saprolite/soil regolith in which 14-C-gibbsite model ages deep within the profile (C-horizon) average about 8000 years. Near the surface (A- and B-horizon) 14-C-gibbsite model ages range from 2100 to 4200 years. Near-surface quartz has acquired 26-Al and 10-Be inventories suggesting it has a residence time of at least 90,000 years. This age disparity supports the notion that secondary minerals undergo significant recrystallization as a weathering front propagates into the landscape. Stable carbon isotopic data (fit via least-squares and a diffusion-based depth function) results in an estimate of 82 gC m-2 y-1 for the soil respiration rate. This long-term rate estimate is an order of magnitude less than the short-term annual efflux rate of 950 gC m-2 y-1 measured at the mixed deciduous forest in the Panola watershed. This rate disparity may in part, reflect climate change in the S. E. United States over the period of gibbsite mineralization (i.e., cooler and seasonally drier Holocene conditions) and/or the need to refine soil respiration models used to relate relict stable carbon isotopic measurements to ancient atmospheric PCO2 estimates. These results suggest that using paleosol mineral proxies to understand terrestrial-atmospheric relationships may be biased toward a recording of long-term soil respiration rates.

Our ignorance stems partially from logistical and political inaccessibility and partially from the paucity of organic matter for radiocarbon dating. However, newly developed dating techniques employing cosmogenic radionuclides and optically stimulated luminescence (OSL) can now constrain the timing of glaciation in these high-altitude environments. During the last few years we have applied these techniques in a series of studies in the Hindu Kush, the Karakoram Mountains (Hunza valley, Ladakh), the Himalayas (Garhwal, Lahul, Khumbu) and Tibet (Qilian Shan, La Ji Shan, Anyemaqen, Nianbaoyeze. Gonga Shan) to help constrain the timing of glaciation and to test whether glaciation was synchronous throughout the region and with climate change recorded in Northern Hemisphere ice sheets and oceans. The reliability of these dating techniques is currently limited by several factors. For OSL partial bleaching is most significant, although low luminescence sensitivity can also be a factor. For cosmogenic dating these include uncertainties in cosmogenic radionuclide production rates, in determining the extent of inheritance and the effects of erosion, and in the geomorphic stability of the dated boulders. We have partially overcome these problems by intense multiple sampling and by comparison of OSL and cosmogenic radionuclide dates from the same locations. We have now determined more than 250 cosmogenic radionuclide and OSL dates. These dates show that glaciation was broadly synchronous around the edges of Tibet and that the regional LGM occurred during MIS-3. Minor glacial advances followed during the global LGM (MIS-2), the Late Glacial, early-mid Holocene, and historical times. When compared with other records, our results suggest that the regional LGM, the Late Glacial and the early Holocene advances are partially a consequence of a positive mass balance related to increased precipitation at high altitudes associated with a strengthened summer, south-Asian monsoon. The glacial advance during MIS-2 is in phase with the cooling observed in the Northern Hemisphere Ice Sheets and oceans.

The method relies on the polarization induced at the boundary between soil and buried metal to produce a measurable phase difference between the injected current and the measured voltage. When natural sources of induced polarization are smaller than those due to buried metal objects, then tomographs of impedance phase indicate regions were metal-soil polarization may be present. Relatively large negative phases may indicate regions were the buried UXO is located. Unexploded ordnance is typically detected using magnetic surveys or conventional metal detectors. These techniques provide limited information regarding the depth of burial of potential targets and are adversely impacted by the presence of metal objects near the surface, such as fences, building foundation, or buried utilities. The EIT method can provide depth and position information on objects located below the surface, and can be deployed around buildings, providing information regarding what lies beneath them. Two controlled tests were performed at a field site containing UXO buried in known locations. Both tests produced a phase anomaly of about 20 milliradians, which closely matched the known location of buried UXO objects.

Complex finite-difference equations were solved using either biconjugate gradient (Bi-CG) method or quasi-minimal residual (QMR) method. A symmetric successive over-relaxation (SSOR) preconditioner was implemented for both solvers. A second-order Laplacian roughness operator was employed for the regularization of the 3-D underdetermined inverse problem. The linearized inversion requires the solution of a complex Hermitian system of equations. The solution of this system uses an efficient complex-conjugate gradient algorithm with a diagonal preconditioner to obtain the parameter change vector. This program was implemented in FORTRAN 90 with the dynamic memory allocation for an efficient memory usage. Synthetic data tests showed that our forward solutions were accurate and the inverse algorithm was able to reconstruct the synthetic model. The analysis of complex resistivity data offers important additional information that could be useful in discrimination of aquitards, saline zones or presence of non-aqueous phase liquids (NAPLs). An example is shown using the algorithm for the inversion of scale model results. Additional phase data helped distinguish different targets.

Environmental and engineering problems require new methods for interpreting the velocity data in terms of sub-surface soil distribution. Recent advances in laboratory measurement techniques have provided high quality velocity data for soils at low pressures that can be used to improve interpretation of field data. We show how laboratory data can be used to infer lithology from field data. We use laboratory ultrasonic velocity measurements from artificial soils made by combining various amounts of sand and peat moss.

In simulations in which there is no fresh water forcing due to ice freezing or melting, the salinity minimum associated with Antarctic Intermediate Water (AAIW) is much weaker than in simulations of the present-day ocean. This suggests that this salinity minimum is maintained in part by a steady supply of fresh water from melting of Antarctic sea ice. In addition, in our simulations with no fresh water forcing due to sea ice, vertical salinity and density gradients in the Southern and Arctic Oceans are weaker than in simulations of the present-day ocean. This supports the notion that that these gradients are maintained in part by fresh water forcing due to the seasonal cycle of freezing and melting of sea ice. As a result, loss of sea ice due to global warming would tend to decrease the stability in parts of the ocean; this opposes the well- known tendency of global warming to increase ocean stability by warming the upper ocean. Changes in stratification are related to changes in uptake of transient tracers (such as anthropogenic CO2) because stratification influences amounts of vertical mixing. Thus, these results suggest that rates of ocean uptake of transient tracers (notably anthropogenic CO2) might not slow down as much as previously supposed as atmospheric CO2 concentrations increase. A simulation of increasing atmospheric CO2 performed with our ocean-atmosphere-sea ice model shows that the surface mixed layer deepens after atmospheric CO2 concentrations start to increase. Our results therefore suggest that Southern Ocean uptake of anthropogenic JF - [np]. 24-28 Jan 2000.

We propose an alternate capture and sequestration method which hydrates CO_{2}-rich power-plant gases with seawater to produce a carbonic acid solution that in turn is reacted on- site with carbonate mineral (e.g., limestone) to form Ca{2+} and bicarbonate in solution. This bicarbonate solution is then released and diluted in the ocean where it would add minimally to the existing, large pool of these ions in the sea. Such a process is geochemically similar to carbonate weathering and dissolution processes which would have otherwise occurred naturally, but over many millennia. Using a schematic model of ocean chemistry and transport we show that this process would increase ocean alkalinity, effectively neutralizing CO_{2} acidity and isolating anthropogenic carbon from the atmosphere. Relative to atmospheric release or direct CO_{2} injection, this method would greatly expand the capacity of the ocean to store anthropogenic carbon while minimizing environmental impacts of this carbon on ocean biota. Additionally, this technique appears to be less energy intensive and less expensive than previously proposed CO_{2} capture and ocean sequestration schemes. We calculate a an energy penalty of about 20\% and a cost range of \27 to \37 per tonne CO_{2} sequestered, dependent on reactor configuration and on carbonate and water availability and transport. These compare with \90 to \180/tonne CO_{2} and >>20\% energy penalty estimated for direct ocean CO_{2} injection. JF - [np]. 24-28 Jan 2000.

The Barbados coral based record is a unique paleoceanographic data set because of its discrete nature which is irrecoverable from open tropical marine records. It has an equivalent sedimentation rate in excess of 600cm/kyr where not only the annual signal is uniquely preserved but seasonality as well. Oxygen isotope values during the late glacial and LGM (16 to 20 14Ckyrs; 19-24 cal-kyrs) are 2.3 per mil heavier than corresponding living specimens, and indicate a regional cooling on the order of 4.5C. There is also an isotopic expression of the Bolling-Pre Boreal climate oscillation, with values reflecting a cooling during the Younger Dryas. Sea surface temperature seasonality, a key diagnostic of the state of the climate system, remained the same or slightly less than present and indicates that the observed coolings were a change in the mean state of the western tropical Atlantic. Synchronous climate change between the northern and southern hemispheres in conjunction withvariable tropical sea surface temperatures challenge the paradigm that climate change only cascades from variations in North Atlantic Deep Water production.

A ``reduced'' grid in which the number of cells in the longitudinal direction is reduced toward high-latitudes, keeping the longitudinal width of the resulting cells as uniform as possible, is applied to a three-dimensional primitive equation ocean-climate model. This grid consists of subgrids which interact at interfaces along their northern and southern boundaries, where the resolution changes by a factor of three. Algorithms are developed to extend the finite difference techniques to this interface, focusing on the conservation required to perform long time integrations, while preserving the staggered spatial arrangement of variables and the numerics used on subgrids. The common alternative used to reduce the timestep restriction caused by the spherical grid is the filtering of high- frequency modes from the high-latitude solution. The reduced grid allows an increased timestep while eliminating the need for filtering and reduces execution time per model step by roughly 20percent. The reduced grid model is implemented for parallel computer architectures with two-dimensional domain decomposition and message passing, with speedup results comparable to those of the original model. Results of model runs are presented to show the effect on the solution, run time, and parallel execution. JF - [np]. 24-28 Jan 2000.

This meteorite experienced minor alteration and a low degree of thermal metamorphism (petrologic type 3.1) and escaped post-accretional brecciation. The alteration resulted in the formation of several minerals, including fayalite, hedenbergite which typically occur as veins. Fayalite and hedenbergite in MAC 88107 formed during late-stage, low-T ( approximately 150-200 degrees C) aqueous alteration. The data for MAC 88107 extend the evidence for an early onset of aqueous activity on chondrite parent bodies and reinforce the conclusion that liquid water played an important role in the chemical and mineralogical evolution of the first chondritic planetesimals.

In this evaluation of potential indicators of in situ anaerobic alkylbenzene metabolism, laboratory and field data are reviewed for two classes of aromatic acids: (i) benzylsuccinate, E-phenylitaconate, and their methyl homologs, and (ii) benzoate, and methyl, dimethyl-, and trimethylbenzoates. The review includes previously unpublished field data from a hydrocarbon-contaminated site in Fallon (Nevada), at which both classes of metabolites were detected in groundwater. The two classes of compounds were evaluated with respect to specificity (i.e., unique biochemical relationship to a specific alkylbenzene), stability, and generation as degradation intermediates versus dead-end products; recent developments in the biochemistry of anaerobic toluene and xylene degradation were incorporated in this evaluation. In general, benzylsuccinates/E-phenylitaconates are superior to benzoates in terms of their very high specificity to their parent hydrocarbons and their lack of commercial and industrial sources. They are also uniquely indicative of anaerobic conditions. All of the benzoates, benzylsuccinates, and E-phenylitaconates are relatively stable chemically and (with the exception of benzoate) biologically under anaerobic conditions, based on the limited data available. Although benzoate, benzylsuccinate, and E-phenylitaconate are intermediates of anaerobic toluene mineralization to carbon dioxide, their methyl homologs can be either mineralization intermediates or cometabolic dead-end products of alkylbenzenes, depending on the bacteria involved. Benzoates are far more commonly reported in field studies of hydrocarbon-contaminated aquifers than are benzy1succinates and E-phenylitaconates, although it is not clear whether this is an accurate representation of the relative occurrence of these metabolites at contaminated sites, or whether it instead reflects the limited range of target analytes used in most field studies to date.

Tritium in the subsurface complicated the task of treating groundwater with conventional methods. The method involved dissolved hydrogen as an electron donor, in the presence of a palladium-on-alumina catalyst. Chlorinated aliphatic compounds were reduced to non-chlorinated hydrocarbons. Trichloroethylene, tetrachloroethylene and carbon tetrachloride were effectively remediated.

The frequency of chromosome translocations in individuals exposed to low to medium doses of whole-body radiation serves these goals. Recent advances in chromosome painting using fluorescence in situ hybridisation (FISH) facilitate fast and reliable measurement of chromosome translocations, a kind of DNA damage linked to both prior clastogenic exposure and to human health risk. Here, results from this laboratory on issues of FISH-based radiation biodosimetry are discussed.

An integrated pilot-scale MSO demonstration facility has been installed and operated at Lawrence Livermore National Laboratory (LLNL). This facility, which has been operational since December 1997, was built to demonstrate the capability of processing organic feed at a commercially useful scale (5-7 kg/h). The integrated MSO treatment train consists of several subsystems:a primary MSO processor (reaction vessel), an off-gas conditioning system, a salt recycle system, and a ceramic final forms immobilization system. The MSO/off-gas system began operations in December 1997, while the salt recycle system and the ceramic final forms immobilization system were activated in May 1998 and September 1998, respectively. During FY98, we have successfully conducted tests in the MSO facility on a variety of liquid and solid organic feeds: chlorinated solvents, tributyl phosphate/kerosene mixtures, PCB-contaminated waste oils and solvents, shredded booties and coveralls, plastic pellets, ion-exchange resins, activated carbon, several radioactive-spike organics, and two well-characterized low-level liquid mixed wastes. This paper presents the results from the operation of the integrated pilot-scale MSO system for the treatmentof several solid feeds including activated carbon, ion exchange resin, plastic pellets, and shredded booties and gloves.

The VSP method consisted of a multilevel hydrophone tool deployed down several wells. Multiple offset surface shotpoints were recorded at multiple azimuths around each well head, using an impact source. The VSP data were processed and inverted to produce p-wave interval velocities. These velocity sections were then projected into a model of the survey volume, together with borehole log information and other geologic information, to produce a 3-D visualization which aided the location and interpretation of aquifer boundaries below the water table. The final image displayed several low velocity zones, and these were attributed to partially saturated pore spaces, possibly both natural, or pump induced by air suction. Low velocity layers appeared above several actively pumped aquifers, and it was concluded that the multi-offset, multi-azimuth, VSP method may be suitable for mapping both aquifer channels, and zones of pumping influence.

The goal was to evaluate significant trends in the data that relate plume behavior to site variables (e.g., source strength, mean groundwater velocity, reductive dehalogenation regime) through correlation and population analyses. Data from 65 sites (government facilities, dry cleaners, landfills) were analyzed, yielding 247 individual CVOC plumes by compound. Data analyses revealed several trends, notably correlations between plume length and maximum observed concentration (presumably reflecting the source term) and mean groundwater velocities. Reductive dehalogenation, indicated by daughter products and groundwater geochemistry, appears to exert a relatively subtle effect on plume length, apparent only after the contributions of source strength and groundwater velocity are factored out. CVOC properties (K sub(oc), Henry's Law constant) exert significant effects on variability in maximum observed concentrations between sites but hold little influence on plume length. Probabilistic plume modeling, entailing Monte Carlo simulation of an analytical solution for average plume behavior with parameter distributions derived from site data, was used to produce a synthetic plume set for comparison with field data. Modeling results exhibited good agreement with field data in terms of parameter sensitivity.

Elastic numerical modeling is an essential tool to develop that understanding. While 2-D elastic modeling is in common use, 3-D elastic modeling has been too computationally intensive to be used routinely. Recent advances in computing hardware, including commodity-based hardware, have substantially reduced computing costs. These advances are making 3-D elastic numerical modeling more feasible. A series of example 3-D elastic calculations were performed using a complicated structure, the SEG/EAGE salt structure. The synthetic traces show that the effects of shear wave propagation can be important for imaging and interpretation of images, and also for AVO and other applications that rely on trace amplitudes. Additional calculations are needed to better identify and understand the complex wave propagation effects produced in complicated structures, such as the SEG/EAGE salt structure.

AN - 69413701; 10635990 AB - This study was conducted to determine the utility of deletion spectrum and mutant frequency (MF) of the hypoxanthine phosphoribosyl transferase gene (HPRT) as indicators of radiation exposure in Russian Liquidators who served in 1986 or 1987 in the clean up effort following the nuclear power plant accident at Chernobyl. HPRT MF was determined using the cloning assay for 117 Russian Controls and 122 Liquidators whose blood samples were obtained between 1991 and 1998. Only subjects from whom mutants were obtained for deletion analysis are included. Multiplex PCR analysis was performed on cell extracts of 1080 thioguanine resistant clones from Controls and 944 clones from Liquidators. Although the deletion spectra of Liquidators and Controls were similar overall, the Liquidator deletion spectrum was heterogeneous over time. Most notable, the proportion of total gene deletions was higher in 1991-1992 Liquidators than in Russian Controls (chi 2 = 10.5, p = 0.001) and in 1993-1994 Liquidators (chi 2 = 8.3, p = 0.004), and was marginally elevated relative to 1995-1996 Liquidators (chi 2 = 3.3, p = 0.07). This type of mutations has been highly associated with radiation exposure. Total gene deletions were not increased after 1992. Band shift mutations were also increased in the 1991-1992 Liquidators but were associated with increased MF of both Liquidators and Controls (p = 0.009), not with increased MF in 1991-1992 Liquidators (p = 0.7), and hence are not believed to be associated with radiation exposure. Regression analysis demonstrated that relative to Russian Controls HPRT MF was elevated in Liquidators overall when adjusted for age and smoking status (37%, p = 0.0001), and also was elevated in Liquidators sampled in 1991-1992 (72%, p = 0.0076), 1993-1994 (22%, p = 0.037), and 1995-1996 (62%, p = 0.0001). In summary, HPRT MF was found to be the more sensitive and persistent indicator of radiation exposure, but the specificity of total gene deletions led to detection of probable heterogeneity of radiation exposure within the exposed population.

Our ability to estimate natural climate variability, against which claims of anthropogenic signal detection must be made, is reviewed. The current situation suggests control runs of global climate models may give the best estimates of natural variability on a global basis, estimates that appear to be accurate to within a factor of 2 or 3 at multidecadal timescales used in detection work. Present uncertainties in both observations and model-simulated anthropogenic signals in near-surface air temperature are estimated. The uncertainty in model simulated signals is, in places, as large as the signal to be detected. Two different, but complementary, approaches to detection and attribution are discussed in the context of these uncertainties. Applying one of the detection strategies, it is found that the change in near-surface, June through August air temperature field over the last 50 years is generally different at a significance level of 5% from that expected from model-based estimates of natural variability. Greenhouse gases alone cannot explain the observed change. Two of four climate models forced by greenhouse gases and direct sulfate aerosols produce results consistent with the current climate change observations, while the consistency of the other two depends on which model's anthropogenic fingerprints are used. A recent integration with additional anthropogenic forcings (the indirect effects of sulfate aerosols and tropospheric ozone) and more complete tropospheric chemistry produced results whose signal amplitude and pattern were consistent with current observations, provided the model's fingerprint is used and detection carried out over only the last 30 years of annually averaged data. This single integration currently cannot be corroborated and provides no opportunity to estimate the uncertainties inherent in the results, uncertainties that are thought to be large and poorly known. These results illustrate the current large uncertainty in the magnitude and spatial pattern of the direct and indirect sulfate forcing and climate response. They also show detection statements depend on model-specific fingerprints, time period, and seasonal character of the signal, dependencies that have not been well explored. Most, but not all, results suggest that recent changes in global climate inferred from surface air temperature are likely not due solely to natural causes. At present it is not possible to make a very confident statement about the relative contributions of specific natural and anthropogenic forcings to observed climate change. One of the main reasons is that fully realistic simulations of climate change due to the combined effects of all anthropogenic and natural forcings mechanisms have yet to be computed. A list of recommendations for reducing some of the uncertainties that currently hamper detection and attribution studies is presented.

Based on this comparison, a preferred methodology is presented. Ground-motion-simulation techniques are divided into two general methods: kinematic- and composite-fault models. Green's functions of three types are evaluated: stochastic, empirical, and theoretical. A hybrid scheme is found to give the best fit to the Northridge data. Low frequencies (1 Hz) are calculated using a composite-fault model with a fractal subevent size distribution and stochastic, bandlimited, white-noise Green's functions. At frequencies below 1 Hz, theoretical elastic-wave-propagation synthetics introduce proper seismic-phase arrivals of body waves and surface waves. The 3D velocity structure more accurately reproduces record durations for the deep sedimentary basin structures found in the Los Angeles region. At frequencies above 1 Hz, scattering effects become important and wave propagation is more accurately represented by stochastic Green's functions. A fractal subevent size distribution for the composite fault model ensures an omega (super -2) spectral shape over the entire frequency band considered (0.1-20 Hz).

Because monitoring data at release locations are typically sparse, spatial variations in geochemical indicator parameters are often called upon as indirect evidence of biotransformation. These parameters include concentrations of electron acceptors (O sub(2), NO sub(3) super(-), SO sub(4) super(2-)), reduced redox reaction by-products (Fe super(2+), Mn super(2+), CH sub(4)), as well as bicarbonate alkalinity, pH and E sub(h). However, background variability in a number of these parameters complicates the task of data interpretation, particularly in the case of small data sets. In this study, correlation analyses are applied to geochemical indicator data at six hydrocarbon groundwater contamination sites in California to identify which parameters are the most reliable indicators. The results of the analyses suggest that the most direct indicators of the local redox environment - Fe super(2+), Mn super(2+), CH sub(4), E sub(h) - yield the most consistent evidence of hydrocarbon biotransformation. Indicators which rely largely on mass balance - O sub(2), NO sub(3) super(-), SO sub(4) super(2-), alkalinity - appear to be less reliable. These findings may provide guidance in both the collection and interpretation of groundwater monitoring data at hydrocarbon contamination sites.

The older event occurred between ca. 30 and 24 Ma during movement along the north-dipping Gangdese thrust. The development of this thrust caused extensive denudation of the Gangdese batholith in its hanging wall and underthrusting of the Xigaze forearc strata in its footwall. Examination of timing of major tectonic events in central Asia suggests that the initiation of the Gangdese thrust was approximately coeval with the late Oligocene initiation and development of north-south shortening in the eastern Kunlun Shan of northern Tibet, the Nan Shan at the northeastern end of the Altyn Tagh fault, the western Kunlun Shan at the southwestern end of the Altyn Tagh fault, and finally the Tian Shan (north of the Tarim basin). Such regionally synchronous initiation of crustal shortening in and around the plateau may have been related to changes in convergence rate and direction between the Eurasian plate and the Indian and Pacific plates. The younger thrusting event along the Yalu River valley occurred between 19 and 10 Ma along the south-dipping Great Counter thrust system, equivalent to the locally named Renbu-Zedong thrust in southeastern Tibet, the Backthrust system in south-central Tibet, and the South Kailas thrust in southwest Tibet. The coeval development of the Great Counter thrust and the North Himalayan granite-gneiss dome belt is consistent with their development being related to thermal weakening of the north Himalayan and south Tibetan crust, due perhaps to thermal relaxation of an already thickened crust created by the early phase of collision between India and Asia or frictional heating along major thrusts, such as the Main Central thrust, beneath the Himalaya.

AN - 52413616; 2000-006232 AB - The hypothesis that the Himalayan orogen was a climatically significant coupled source and sink for atmospheric CO (sub 2) during the Cenozoic is evaluated in light of the timing, duration and CO (sub 2) fluxes associated with Himalayan metamorphism and chemical weathering. We suggest that diachronous Eohimalayan metamorphism occurred over a approximately 20 m.y. time span (Middle Eocene to Early Oligocene) with total metamorphic CO (sub 2) production of approximately 4-10X10 (super 18) mol. Because this is much greater than the amount of carbon stored in the atmosphere and oceans, and because uplift and accelerated erosion began at least approximately 5 m.y. after the peak of metamorphism, we conclude that it is implausible that CO (sub 2) produced by metamorphism in the Himalayan orogen was consumed millions of years later by erosion-enhanced weathering in this orogen. Assuming a global climate/silicate-weathering feedback, we estimate that metamorphic CO (sub 2) degassing from the Himalayan orogen would have produced a warming of <0.5 degrees C, and enhanced weathering in this orogen would have produced a cooling of <0.2 degrees C; thus, direct climate effects of this degassing and weathering were likely to have been minor.

The measurements included visible band photometry on both events, as well as filtered 5890 Aa all-sky images of the Na airglow. Also, for the 3:06 A.M. event, we obtained an infrasound measurement of the hydrodynamic yield. For the 1:32 A.M. event, we obtained a set of visible band charge-coupled device (CCD) camera images of the meteor train for times extending to 30 min after the initial impact. The measurement results have been combined to derive an optical efficiency for the intense early-time optical flash, and the total explosion yields and masses for both of the meteors. We have also done a set of numerical radiation, hydrodynamic, and chemistry computations to investigate the nature and distribution of the long-lasting airglow. We attribute the brightest visible airglow to atomic O 5577 Aa line emission, with additional contributions from atomic Na emission and NO (sub 2) chemiluminescence. The near-infrared atmospheric bands of molecular O (sub 2) should be very strong as well. All of the band emissions are expected to show a hollow limb-brightened structure.

Solute concentration simulated the expected effects of boiling and evaporation in the vadose waters surrounding the YM waste packages. LCS, a candidate material for the outer layer in current multibarrier waste-package designs, corroded at low general rates with no localized corrosion in deaerated waters at 25 degree C concentrated to 10 times (X), 100X, and 1,000X the reference water-well concentrations. Higher water temperatures (up to 90 degree C) and concentrations (100X and 1,000X) favored precipitation of silicate surface layers that further decreased corrosion rates and significantly increased apparent pitting potentials in deaerated water. Aeration increased corrosion rates significantly in 10X water at 25 degree C, but had lesser effects at 100X and 1,000X. Aeration and chloride additions also significantly degraded the protectiveness of inhibitive precipitate surface films. Added soluble Fe super(3+) in aerated 10X waters increased general corrosion at 25 degree C and initiated pitting at still higher concentrations and temperatures.

AN - 70742711; 10497278 AB - Genetic recombination involves either the homo-logous exchange of nearly identical chromosome regions or the direct alignment, annealing and ligation of processed DNA ends. These mechanisms are involved in repairing potentially lethal or mutagenic DNA damage and generating genetic diversity within the meiotic cell population and antibody repertoire. We report here the identification of a mouse gene, termed mExo1 for mouse exonuclease 1, which encodes a approximately 92 kDa protein that shares homology to proteins of the RAD2 nuclease family, most notably human 5' to 3' exonuclease Hex1/hExo1, yeast exonuclease 1 (Exo1) proteins and Drosophila melanogaster Tosca. The mExo1 gene maps to distal chromosome 1, consistent with the recent mapping of the orthologous HEX1 / hEXO1 gene to chromosome 1q42-q43. mExo1 is expressed prominently in testis, an area of active homologous recombination, and spleen, a prominent lymphoid tissue. An increased level of mExo1 mRNA was observed during a stage of testis development where cells that are actively involved in meiotic recombination arise first and represent a significant proportion of the germ cell population. Comparative evaluation of the expression patterns of the human and mouse genes, combined with previous biochemical and yeast genetic studies, indicate that the Exo1-like proteins are important contributors to chromosome processing during mammalian DNA repair and recombination.

These have been interpreted as either taphonomically mixed or representative of communities that no longer exist. Accelerator mass spectrometry (super 14) C dates (n = 60) on single bones of stratigraphically associated fossil micromammals from two American and two Russian sites document for the first time that currently allopatric mammals occurred together between 12,000 and 22,000 yr B.P. on two continents. The existence of mammal communities without modern analogs demonstrates that Northern Hemisphere biological communities are ephemeral and that many modern biomes are younger than 12 ka.

Correct interpretation of underground fluid migration from seismic data requires a quantitative understanding of the relationships among the velocity data and fluid properties in the form of fluid substitution formulas, and these formulas are very commonly based on Gassmann's equations. Nevertheless, confusion persists about the basic assumptions and the derivation of Gassmann's (1951) well-known equation in poroelasticity relating dry or drained bulk elastic constants to those for fluid-saturated and undrained conditions. It is frequently stated, for example, but quite incorrect to say that Gassmann assumes the shear modulus is constant (i.e., mechanically independent of the presence of the saturating fluid). This note clarifies the situation by presenting an unusually brief derivation of Gassmann's relations that emphasizes the true origin of the constant shear modulus result, while also clarifying the role played by the shear modulus in the derivation of the better understood result for the bulk modulus.

TEM was used to identify crystallographical features that might influence dissolution in albite, anorthite and labradorite. HAFM and SEM images show various stages of surface attack under varying conditions. The results suggest that an altered layer forms on anorthite despite the lack of bridging Si-O-Si linkages, and the thickness of this layer does not increase continuously but shows steady state behaviour, e.g. by healing of scan fields. There is a distinct junction between this altered layer, showing step-like patterns, and the underlying anorthite.

Environmental and engineering problems require new methods for interpreting the velocity data in terms of sub-surface soil distribution. Recent advances in laboratory measurement techniques have provided high quality velocity data for soils at low pressures that can be used to improve interpretation of field data. We show how laboratory data can be used to infer lithology from field data. We use laboratory ultrasonic velocity measurements from artificial soils made by combining various amounts of sand and peat moss.

In this article we describe the results of finite-difference simulations for the 1989 Loma Prieta, CA, earthquake, with a 3D seismic velocity model for the San Francisco Bay region and a heterogeneous slip model of the source. Additionally, we explore the sensitivity of the synthetics to the major geologic structures in the velocity model. The San Francisco Bay region (particularly the Loma Prieta region) is a unique area for the study of 3D wave propagation because of the pronounced lateral velocity contrasts across the strike-slip faults of the region. Understanding the effects of such long wavelength structure is doubly important when considering a source located close to such a contrast. Our simulations show that the lateral velocity contrast across the San Andreas Fault (SAF) would be expected to substantially affect the propagation of elastic waves radiated from a source in the Loma Prieta region. Indeed, we find that the refraction of energy by the SAF serves to reduce ground motions at stations located along the San Francisco Peninsula, and the Quaternary and Tertiary alluvial basins of the San Francisco Bay region are found to amplify and extend the duration of ground motions in Santa Clara Valley, Livermore Valley, and San Pablo Bay. We find that the 3D model as currently defined accurately describes the spatial variation of peak ground velocity for frequencies less than 0.5 Hz, which suggests that this model may be used to estimate ground motions for future earthquake scenarios.

The combined explosive yield from these tests was 107 million t (million t TNT equivalents). This testing produced close-in fallout debris that was contaminated with quantities of radioactive fission and particle activated products, and unspent radioactive nuclear fuel that entered the aquatic environment of the atolls. Today, the sediments in the lagoons are reservoirs for tens of TBq of the transuranics and some long-lived fission and activation products. The larger amounts of contamination are associated with fine and coarse sediment material adjacent to the locations of the high yield explosions. Radionuclides are also distributed vertically in the sediment column to various depths in all regions of the lagoons. Concentrations greater than fallout background levels are found in filtered water sampled over several decades from all locations and depths in the lagoons. This is a direct indication that the radionuclides are continuously mobilized to solution from the solid phases. Of particular importance is the fact that the long-lived radionuclides are accumulated to different levels by indigenous aquatic plants and organisms that are used as food by resident people. One might anticipate finding continuous high contamination levels in many of the edible marine organisms from the lagoons, since the radionuclides associated with the sediments are not contained and are available to the different organisms in a relatively shallow water environment. This is not the case. We estimate that the radiological dose from consumption of the edible parts of marine foods at Enewetak and Bikini is presently approximately 0.05% of the total 50-year integral effective dose from all other exposure pathways that include ingestion of terrestrial foods and drinking water, external exposure and inhalation. The total radiological dose from the marine pathway is dominated by the natural radionuclides, super(210)Po and super(210)Pb.

Low (super 14) C activities in some of the springs are interpreted to result from the dissolution of diffuse emissions of magmatic CO (sub 2) , even though volcanic activity has not occurred in this area for more than 1300 yr. On the basis of dissolved magmatic carbon concentrations in the springs, we infer a diffuse magmatic CO (sub 2) degassing rate of 3.4X10 (super 5) kg/yr per kilometer of arc for the central Oregon Cascades. The CO (sub 2) flux calculated from estimates of the mean magmatic intrusion rate and experimentally determined values of CO (sub 2) content in melts is consistent with that determined from our measurements of the dissolved CO (sub 2) flux at springs.

Analyses are presented of pillow-rim glasses for noble gas concentrations and isotopic compositions, major elements, Be and B. Many of the rim glasses and fragmental glasses from this seamount have high Cl and high ratios of Cl to K and other incompatible elements relative to submarine glasses from other Hawaiian volcanoes. It is suggested that this reflects widespread assimilation of sea-water-derived Cl-rich components such as saline brine, halite or Fe oxyhydroxides. Such assimilation may also explain the contamination of Loihi lavas with atmospheric-derived noble gases, with brines as the major assimilant. Sea-water-like Br/Cl ratios in some pillow-rim glasses indicate sea-water-derived brines as the primary assimilant as halite and other Cl-rich minerals strongly fractionate this ratio.

Using in situ atomic force microscopy, it is shown that at the very-near equilibrium where organisms synthesize minerals, crystallographic controls on rates of advancement along individual monomolecular step edges can show a reversed growth morphology and a novel pseudo-isotropic form. Rate data are correlated with growth hillock structures and show how crystallographic anisotropy leads to the direction-specific behaviour of individual steps and the formation of unusual morphologies. The results show the sensitivity of near-equilibrium growth kinetics to minute impurity levels. AFM images illustrate the growth hillock structures.

Analyses, by ion probe, are presented of mammal dentine and enamel for 21 major and trace elements, and by EPM for major oxides and trace elements for the fossil and modern samples. The results confirm that fossil tooth chemistry is controlled by the diagenetic precipitation of secondary minerals and by the alteration of biogenic apatite. Increases in U, REE, F and perhaps Sr in the fossil as compared to modern tooth samples are due to alteration of the Ca and OH sites in the original apatite; increases in Al, Si, Mn, Fe, Ba and perhaps Cu are attributed to contamination in the fossil samples by diagenetic hydroxides + or - clay minerals.

Several of these deposits originally contained several hundred kilograms of layered tektite fragments, and one fragmented mass may have been as large as 1000 kg. This is the largest single deposit of tektites yet reported. In this region, layered tektite fragments are found in isolated clusters usually associated with a pebbly laterite horizon that is 0-1 m below the surface. Near Khe Sanh, Vietnam, we estimate the abundance of layered tektite fragments to be approximately 100 g/m (super 2) . This is greater than five times the abundance estimated for northeast Thailand (Fiske et al., 1996). In a region that extends from northeast Thailand, through central Laos, and into central Vietnam, we found only layered tektites, which confirmed the existence of a large (>50 000 km (super 2) ) subfield of the Australasian strewn field with only layered tektites.

A global map of absolute thorium abundances on a 2 degrees by 2 degrees equal-area pixel scale is presented using new detector modeling results and low altitude LP data. Because thorium is relatively abundant in KREEP-rich material, these data provide fundamental information regarding the locations and importance of terranes that are rich in KREEP bearing materials.

This methodology explicitly incorporates uncertainty (including the statistical parameter uncertainty arising from a limited number of hydraulic conductivity measurements) and variability (such as the variability in individual physiology) in all parameters, resulting in a nested Monte Carlo procedure. The methodology is demonstrated using a hypothetical case study where the sensitivity of various end points (including human health risk) to increased sampling of hydraulic conductivity are explored. It is shown that an increase in the number of measurements of hydraulic conductivity decreases the error in and uncertainty of predicted human health risk. Cost-benefit curves are developed and incorporated into a simple decision framework to determine the number of samples of hydraulic conductivity that are needed to accurately predict the human health risk from a contaminated site.

In addition, a quantitative structure-activity relationship will be presented correlating the potency of these imidazopyridines to predicted chemical properties. Although no strong linear correlation is found between the potency and the chemical properties, a low dipole moment is found to be a qualitative predictor of high mutagenic potency.

Both are genotoxic in a number of test systems and are carcinogenic in rats and mice. Human exposure to these compounds via dietary sources has been estimated to be under 1 mu g/kg body wt. per day, although most laboratory animal studies have been conducted at doses in excess of 10 mg/kg body wt. per day. We are using accelerator mass spectrometry (AMS), a tool for measuring isotopes with attomole sensitivity, to study the dosimetry of protein and DNA adduct formation by low doses of MeIQx and PhIP in rodents and comparing the adduct levels to those formed in humans. The results of these studies show: 1, protein and DNA adduct levels in rodents are dose-dependent; 2, adduct levels in human tissues and blood are generally greater than in rodents administered equivalent doses; and 3, metabolite profiles differ substantially between humans and rodents for both MeIQx and PhIP, with more N-hydroxylation (bioactivation) and less ring oxidation (detoxification) in humans. These data suggest that rodent models do not accurately represent the human response to heterocyclic amine exposure.

Previous studies have suggested that differences in benzene toxicity among strains result from differences in metabolism. Rats and mice were administered [ super(14)C]benzene (i.p.), followed by removal of liver and bone marrow at time intervals up to 48 h postexposure. Protein and DNA were isolated and analyzed by accelerator mass spectrometry. Area under the curves for protein and DNA adducts in bone marrow were greatest in B6C3F sub(1) mouse > DBA/2 mouse > C57BL/6 mouse > Fischer rat. These data are consistent with the hypothesis that metabolic capacity contributes to the difference in benzene's carcinogenicity among species. Additionally, these data suggest that target organ adduct levels correlate with tumorigenicity and thus may be indicative of an individuals risk.

AN - 69995420; 10464479 AB - Metabolites of atrazine were measured in human urine after dermal exposure using HPLC to separate and identify metabolites and accelerator mass spectrometry (AMS) to quantify them. Ring-labeled [14C]atrazine was applied for 24 h with a dermal patch to human volunteers at low (0.167 mg, 6.45 muCi) and high (1.98 mg, 24.7 muCi) doses. Urine was collected for 7 days. The urine was centrifuged to remove solids, and the supernatant was measured by liquid scintillation counting prior to injection on the HPLC to ensure that < 0.17 Bq (4.5 pCi) was injected on the column. A reversed-phase gradient of 0.1% acetic acid in water and 0.1% acetic acid in acetonitrile became less polar with increasing time and separated the parent compound and major atrazine metabolites over 31 min on an octadecylsilane column. Peaks were identified by coelution with known standards. Elution fractions were collected in 1-min increments; half of each fraction was analyzed by AMS to obtain limits of quantitation of 14 amol. Mercapturate metabolites of atrazine and dealkylated atrazine dominated the early metabolic time points, accounting for approximately 90% of the 14C in the urine. No parent compound was detected. The excreted atrazine metabolites became more polar with increasing time, and an unidentified polar metabolite that was present in all samples became as prevalent as any of the known ring metabolites several days after the dose was delivered. Knowledge of metabolite dynamics is crucial to developing useful assays for monitoring atrazine exposure in agricultural workers.

Well-characterized samples of vermiculite and hydrobiotite were exposed to aqueous uranyl under conditions designed to promote surface sorption either at fixed charge ion-exchange sites or at amphoteric surface hydroxyl sites. The local structure of uranium in the sorption samples was directly measured using uranium L (sub 3) -edge extended X-ray absorption fine structure (EXAFS). Polarized L (sub 1) - and L (sub 3) -edge X-ray absorption near-edge structure (XANES) measurements were used to characterize the orientation of uranyl groups in layered samples. X-ray diffraction (XRD) measurements of interlayer spacings were used to assess the effects of ion-exchange and dehydration upon the mineral structure. The most significant findings are: (1) Under conditions which greatly favor ion-exchange sorption mechanisms, uranyl retains a symmetric local structure suggestive of an outer-sphere complex, with a preferred orientation of the uranyl axis parallel to the mineral layers; (2) Upon dehydration, the ion-exchange complexes adopt a less symmetric structure, consistent with an inner-sphere complex, with less pronounced orientation of the uranyl axis; and (3) For conditions which favor sorption at surface hydroxyl sites, uranyl has a highly distorted equatorial shell, indicative of stronger equatorial ligation, and the detection of a neighboring U atom suggests the formation of surface precipitates and/or oligomeric complexes.

Detailed stratigraphical, structural, volcanological and (super 14) C (AMS) geochronological studies, devoted to the reconstruction of the volcanic and deformational history of the Campi Flegrei caldera in the past 12,000 years have been carried out. The results of these studies show that in this time span, intense both volcanic and volcano-tectonic activity was confined inside the Neapolitan Yellow Tuff caldera. Volcanism was concentrated in epochs of intense activity, alternating to periods of quiescence. The I epoch lasted from 12,000 to 9500 years BP giving rise to 34 explosive eruptions, each every 70 years on average. During the II epoch, dated between 8600 and 8200 years BP, six explosive eruptions took place at an average interval of 65 years. The III epoch lasted from 4800 to 3800 years BP and produced 16 explosive and four effusive eruptions which followed each other at mean intervals of 50 years. Eruption vents of the I epoch were located mostly along the marginal faults of the Neapolitan Yellow Tuff caldera, while those of the II epoch aligned on the northeastern sector of this margin. During the III epoch volcanism was confined in the northeastern sector of the Neapolitan Yellow Tuff caldera floor. The caldera floor is disjointed in blocks with variable vertical movements by fault and fracture systems mainly trending NE-SW and NW-SE. The still active resurgence of the caldera floor began soon after its collapse. Onset of both II and III epoch of activity coincides with increase in resurgence rate of La Starza marine terrace, the most uplifted part of the resurgent block.

The photographs cover three swaths along the fault, each about 2-km-long and at least 500-m-wide, near the village of Songshan, at 103.5 degrees E. This high-resolution data set is used to map and measure cumulative horizontal offsets of alluvial terraces and risers that range between 115 and 135 m, and 70 and 90 m, at two sites. Dating these terraces with (super 14) C yields minimum and maximum ages of 8400 and 7600, and 14,200 years B.P., respectively. This leads to a postglacial slip rate of 12 + or - 4 mm/yr, with a most likely minimum value of 11.6 + or - 1.1 mm/yr. The smallest stream offsets observed on the HR photographs range between 8 and 16 m and are interpreted as coseismic displacements of the last few earthquakes with M > or = 8 that ruptured the 220-km-long Tianzhu gap of the fault, west of the Yellow River. Earthquakes of that size within this gap, which has been quiescent for at least 800 years, would recur at intervals of 1050 + or - 450 years. Copyright 1999 by the American Geophysical Union.

Significant features of this tool include its applicability over a broad band of frequencies (f or = 4.5), its ability to provide accurate high-resolution depth estimates, and its ability to provide constraints on event mechanism including isotropic contributions. It also provides estimates of random and model errors and can be used to test hypotheses and investigate sensitivity to and trade-offs between model parameters. We validated this tool and its algorithms by showing that our estimated depths and mechanisms are in excellent agreement with ground-truth depths and mechanisms based on local and regional data. We find that depth can usually be estimated to an accuracy of a few km with a small number of stations. Although complete mechanisms are sometimes poorly resolved, we find that two out of three of the mechanism parameters (strike, dip, rake) are usually well constrained. We illustrate the potential of this technique for regional calibration, special event analysis, and event screening by comparing estimated depths and mechanisms of events in the Middle East and North Africa with those of the National Earthquake Information Center (NEIC) and by comparing our depth and mechanism estimates for the May 11, 1998 India nuclear explosion and a November 8, 1991 earthquake that occurred in the same region.

Accurate modeling of solar radiative forcing due to aerosols from anthropogenic sulfate and biomass burning emissions requires adequate spectral resolution and treatment of spatial and temporal variability. The variation of aerosol spectral optical properties with local relative humidity and dry aerosol composition must be considered. Because the cost of directly including Mie calculations within a climate model is prohibitive, parameterizations from off-line calculations must be used. Starting from a log-normal size distribution of dry ammonium sulfate, we developed optical properties for tropospheric sulfate aerosol at 15 relative humidities up to 99%. The resulting aerosol size distributions were then used to calculate bulk optical properties at wavelengths between 0.175 and 4 mu m. Finally, functional fits of optical properties were made for each of 12 wavelength bands as a function of relative humidity. Significant variations in optical properties occurred across the total solar spectrum. Relative increases in specific extinction and asymmetry factor with increasing relative humidity became larger at longer wavelengths. Significant variation in single-scattering albedo was found only in the longest near-IR band. This is also the band with the lowest single scattering albedo. A similar treatment was done for aerosols from biomass burning. In this case, two size distributions were considered. One was based on a distribution measured for Northern Hemisphere temperate forest fires while the second was based on a measured size distribution for tropical fires. Equilibrium size distributions and compositions were calculated for 15 relative humidities and five black carbon fractions. Mie calculations and band averages of optical properties were done for each of the resulting 75 cases. Finally, fits were made for each of 12 spectral bands as functions of relative humidity and black carbon fraction. These optical properties result in global average forcing from anthropogenic sulfate aerosols of - 0.81 Wm super(-2).

More than fifty years of research on the nitrogen mustards has yielded a broad range of therapeutically useful compounds and a detailed knowledge of the biochemical mechanism of these drugs. Nevertheless, there is much ongoing research on the phosphosphoramidic and other nitrogen mustards to increase their potency and reduce their toxic and mutagenic side effects. To understand the existing nitrogen mustards, and to design the next generation of these drugs, more knowledge is needed about the effects of chemical modifications on their activation and selectivity. Because of the existing knowledge of these drugs, atomic-level chemical modeling can play an important role in the understanding of the phosphoramidic mustard compounds; however, it has not proved straight forward to directly relate the activity of these mustards with simple chemical properties such as bond lengths or atomic charges. Instead, quantum chemical simulations will be required to simulate the activation and alkylation reactions of these compounds, which will require the newest generation of quantum chemical and solvent modeling methods. Additionally, molecular dynamics simulations of the adducted DNA can provide data on the factors favoring crosslinking and its structural consequences. This review summarizes the extensive literature on the metabolism, activation, and action of the phosphoramidic mustards, with an emphasis on the roles that chemical modeling has and will play in the development of this important class of drugs.

The median ratio for 14 meteoric water samples is 2100 X 10 super(-12), corresponding to a super(129)I concentration of 2.5 X 10 super(7) atoms/L, whereas 9 epiphyte samples have a median ratio of 1800 X 10 super(-12). Calculated deposition rates of super(129)I in the continental United States reveal that a small but significant fraction of the atmospheric releases from the nuclear fuel reprocessing facilities at Sellafield, England, and Cap de La Hague, France, is deposited after distribution by long-range transport. The inferred dominant mode of transport is easterly, within the troposphere, mainly in the form of the organic gas methyl iodide.

AN - 69911673; 10415438 AB - The identification of heterocyclic amines (HCAs) in cooked foods has focused attention on the potential health effects from their consumption in the diet. Recent studies have estimated daily dietary intakes of HCAs that vary 10-fold and implicated different cooked meats as the prime source of HCAs in the diet. These varied estimates can be attributed to the different dietary assessment methods used in these studies, as well as the different levels of HCAs ascribed to the most commonly consumed cooked meats. Epidemiological studies utilizing information on dietary practice and food intake have found higher risks for several cancers among individuals consuming the highest levels of HCAs. These studies have highlighted the importance of using information on cooking methods in addition to food intake to accurately estimate dietary exposure to HCAs.

AN - 69873869; 10390343 AB - Ape1, the major protein responsible for excising apurinic/apyrimidinic (AP) sites from DNA, cleaves 5' to natural AP sites via a hydrolytic reaction involving Mg2+. We report here that while Ape1 incision of the AP site analog tetrahydrofuran (F-DNA) was approximately 7300-fold reduced in 4 mM EDTA relative to Mg2+, cleavage of ethane (E-DNA) and propane (P-DNA) acyclic abasic site analogs was only 20 and 30-fold lower, respectively, in EDTA compared to Mg2+. This finding suggests that the primary role of the metal ion is to promote a conformational change in the ring-containing abasic DNA, priming it for enzyme-mediated hydrolysis. Mutating the proposed metal-coordinating residue E96 to A or Q resulted in a approximately 600-fold reduced incision activity for both P and F-DNA in Mg2+compared to wild-type. These mutants, while retaining full binding activity for acyclic P-DNA, were unable to incise this substrate in EDTA, pointing to an alternative or an additional function for E96 besides Mg2+-coordination. Other residues proposed to be involved in metal coordination were mutated (D70A, D70R, D308A and D308S), but displayed a relatively minor loss of incision activity for F and P-DNA in Mg2+, indicating a non-essential function for these amino acid residues. Mutations at Y171 resulted in a 5000-fold reduced incision activity. A Y171H mutant was fourfold less active than a Y171F mutant, providing evidence that Y171 does not operate as the proton donor in catalysis and that the additional role of E96 may be in establishing the appropriate active site environment via a hydrogen-bonding network involving Y171. D210A and D210N mutant proteins exhibited a approximately 25,000-fold reduced incision activity, indicating a critical role for this residue in the catalytic reaction. A D210H mutant was 15 to 20-fold more active than the mutants D210A or D210N, establishing that D210 likely operates as the leaving group proton donor.

These processes resulted in intimate mixing of materials altered to various degrees. In the past, this mixing has been attributed solely to impact processes. However, our investigation of the physical consequences of aqueous alteration processes in bodies accreting from a mixture of silicate and ice grains shows that aqueous alteration was commonly accompanied by substantial gas production. The asteroids may have become so internally pressurized by these gases that the sudden onset of gas release led to partial or complete disaggregation of the body. In some cases, fragments may have escaped completely from the parent asteroid and could potentially have been incorporated into other accreting asteroids. In other cases, fragments originating from different parts of the initial body, having various sizes and temperatures and exhibiting varying degrees of alteration, may have reaccreted into a second-generation object and undergone further stages of alteration. Such events could have been repeated two or three times during the lifetime of (super 26) Al, the likely heat source for these processes.

The International Atomic Energy Agency initiated the International Arctic Seas Assessment Project (IASAP) to study the possible health and environmental effects from disposal of these objects. One outcome of the IASAP was an estimation of the radionuclide inventory and their release rates from these objects. A follow-on concern is the ability to detect the radionuclides released into the water column. The work reported here is the feasibility of using the long-lived radionuclides super(59)Ni, super(99)Tc, and super(236)U encased within these objects, to monitor the breakdown of the containments due to corrosion. The inventories used in the calculations of the annual mass release of super(59)Ni and super(99)Tc are those reported by the IASAP Source Term Working Group (IAEA 1997) from the objects listed in Table I. Using the best estimate discharge scenario, corrosion rates, and methodology of the IASAP Source Term Working Group models [1], the annual activity release (Bq/a) of super(59)Ni, super(99)Tc, and super(236)U were determined for the five disposal sites over the estimated period of release. Conversion to annual mass release (gala) of super(59)Ni, super(99)Tc, and super(236)U was accomplished through the appropriate application of isotopic specific activity (Bq/g). To estimate the concentration of a radionuclide released from a dumped object to seawater, we used a simple equation to predict the average near-field concentration of a radionuclide released from a seabed dump site into a diffusive ocean [2]. Then, the mass of a radionuclide present in a seawater sample is determined from the product of the radionuclide concentration and the volume of the sample. JF - Marine Pollution.

If inhaled metals contribute to pathogenesis of these diseases, identifying, localizing, and quantitating metal deposition(s) within specific target regions of the central nervous system will be critical to our understanding of the mechanisms. Standard analytical techniques used to date require exposure to extremely high concentrations of metals to meet analytical detection limits in small tissue areas. The relevance to lower-dose environmentally relevant exposures and potential protective barriers is therefore questionable. The feasibility of microbeam particle-induced X-ray emission is investigated as a method for rapidly scanning tissues to study the inhalation of metals, nasal permeability, and central nervous system deposition. The optimal beam spot and analysis time used to image the rat olfactory epithelium to facilitate the rapid detection of aluminum localizations were determined. Measurements of aluminum localizations in rat olfactory bulb and brain sections are also presented.

These procedures have the following shortcomings: (1) it is often difficult to identify the proper phase: (Pg or Pn, Sg or Sn); and (2) first arrivals are often masked by noise. Both factors may cause significant location errors. An alternative is to look for maximums of seismic energy time-distance distribution, which are less sensitive to these factors. We measure the time-of-maximum of P and S waves envelopes vs. distance for each available station of the Israel Seismic Network (ISN), thus providing a travel time curve (TTC). The record envelopes are obtained using 1D chi (super 2) optimal detector and 3-6 Hz "short-time-average" time-curves, having enhanced sensitivity for seismic signal arrivals. The corresponding P and S time-of-maximum vs. distance functions are approximated linearly by a least-square method for a set of local earthquakes and quarry blasts. Travel time inversion for location of small events comprises three main steps: (1) cleaning of the records from noise bursts and computation of the envelopes, (2) triggering and identification of the P and S phases and computation of their energy maximums, and (3) maximization of a sum of station residuals as a function of epicenter coordinates. The maximum of the functional is looked for on a 60X60 km grid, step of 2 km, covering different parts of Israel and Jordan. The algorithm is not sensitive to the source depth, thus providing epicenter determination only, but shows to be convenient and robust. As a result of the preliminary study for a set of relatively weak 74 local earthquakes and 58 quarry blasts, M (sub L) approximately 1.5-2.5, we have obtained the accuracy of epicenter estimation + or -6 km for 80-90% of both types of events, which is satisfactory for automatic location.

A velocity-stress formulation of the full elastic wave equations are combined with exact boundary conditions for the surface topography and numerically discretized by an eighth-order F-D method on a staggered grid. We have simulated scattering in 2-D and 3-D from teleseismic P-waves using a plane, vertically incident P-wave and real topography from a 60X60 km (super 2) area including the NORESS array in southeastern Norway. Many field observations that are not easily explained by simpler 2-D cases are shown to better match qualitative effects from 3-D surface topography modeling. These include strong amplifications at hills, complex wave pattern caused by scattering, and directivity of scattered waves. Snapshots and seismograms show clear conversion from P- to Rg- (short period fundamental mode Rayleigh) waves in an area of rough topography in the vicinity of the array site. All results are consistent with numerous observations. By parallellization of the original software, possibilities have been opened for modeling with higher resolution and/or larger areas than before.

This so-called AR-AIC phase picker has been tested successfully and implemented on the Z-component of the broadband station HGN to provide automatic P-phase picks for a rapid warning system. The AR-AIC picker is shown to provide accurate and robust automatic picks on a large experimental database. Out of 1109 P-phase onsets with signal-to-noise ratio (SNR) above 1 from local, regional and teleseismic earthquakes, our implementation detects 71% and gives a mean difference with manual picks of 0.1 s. An optimal version of the well-established picker of Baer and Kradolfer [Baer, M., Kradolfer, U., An automatic phase picker for local and teleseismic events, Bull. Seism. Soc.

This paper reviews the current status of single-station location (SSL) methods--the location of seismic events using records from one three-component broadband digital station. We argue here that SSL methods may ultimately provide the most effective and economical means for monitoring small-magnitude (M approximately 3) seismic events over most of the earth. Potentially, station-event distance and focal depth may be determined accurately by utilizing broadband three-component data and matching observed and synthetic waveforms; station-event azimuth is determinable from the polarization of the P-wave arrival and P coda. However, more research is required before SSL methods become a practical alternative to traveltime-based methods. Currently, the most significant problem is that regional seismograms are strongly dependent on regional crustal structure. Thus, future research efforts should focus both on determining appropriate crustal models in specific regions, and also on improved methods for dealing with regional variations in crustal structure. A second important problem concerns location errors; with SSL they may involve 180 degrees errors in station-event azimuth or other highly non-Gaussian "blunders".

An initial path connecting two points, the source and the receiver, is algorithmically perturbed until it converges to a solution giving a minimum travel-time path. In multi-pathing cases, it is quite possible for an algorithm to converge to a ray path with local minimum travel time. Furthermore, when the velocity structure has discontinuities, there is another serious problem, i.e., how to determine the correct intersection between the ray and the surface of discontinuity. In this paper, a new approach for two-point ray tracing is presented, which uses genetic algorithms (GAs) to overcome these problems. Since GAs are efficient global search techniques, the proposed method guarantees to find a global minimum travel-time path and also the correct intersections. A micro-GA implementation is adopted to further enhance computational efficiency. This approach is suitable for tracing the first arriving seismic waves through a 3-D heterogeneous medium with discontinuities. The method can also find the minimum time paths of later arrivals, such as reflected and refracted waves, by constraining the ray to hit a prescribed interface. The accuracy of the method is demonstrated on the numerical examples.

These inaccuracies are caused by inherent averaging in the model and, as a result, exact data values cannot be directly recovered at a point in the model. Seismic characterization involves cataloging reference events so that inaccuracies in the model can be mapped at these points and true data values can be retained through a correction. Application of these corrections to a new event requires the accurate prediction of the correction value at a point that is near, but not necessarily coincident with the reference events. Given that these reference events can be sparsely distributed geographically, both interpolation and extrapolation of corrections to the new point are required. In this study, we develop a closed form representation of Bayesian kriging (linear prediction) that incorporates variable spatial damping. The result is a robust nonstationary algorithm for spatially interpolating geophysical corrections. This algorithm extends local trends when data coverage is good and allows for damping (blending) to an a priori background mean when data coverage is poor. Benchmark tests show that the technique gives reliable predictions of the correction value along with an appropriate uncertainty estimate. Tests with travel-time residual data demonstrate that combining variable damping with an azimuthal coverage criterion reduces the large errors that occur with more classical linear prediction techniques, especially when values are extrapolated in poor coverage regions. In the travel-time correction case, this technique generates both seismic corrections along with uncertainties and can properly incorporate model error in the final location estimate. Results favor the applicability of this nonstationary algorithm to other types of seismic corrections such as amplitude and attenuation measures. Since this studies original publication, several studies have demonstrated that nonstationary Bayesian kriging provides significant improvement over more conventional correction techniques. Applications have been performed in location and identification and each has demonstrated that this technique can combine the best theoretical earth models with empirical corrections to obtain a more accurate solution. These results and their broad implications for the future calibration of monitoring networks are discussed in a new section that follows the conclusions.

Among all parameters related to event location, the backazimuth estimated with a skew, large-aperture network appears to be the least sensitive to the model error--under these difficult yet realistic conditions. This observation leads to a hypothesis that epicenters could be better constrained through triangulation using backazimuths derived from two skew, large-aperture subnetworks or arrays. If two subnetworks can be found such that the corresponding backazimuths are sufficiently apart (say, they intersect at an angle of 20 degrees or larger), the resulting absolute mislocation associated with the intersection point is often less than 18 km, which is the permissible location accuracy as quoted in the Comprehensive Nuclear Test Ban Treaty (CTBT). The origin time and source depth can then be obtained from a standard location procedure with the approximate epicenter held fixed. If the network cannot be partitioned to provide two "good" backazimuths, then the conventional location procedure (which feeds on the phase picks altogether) can still be used. The proposed algorithm is tested with three events: (1) U.S. explosion Salmon of Oct. 22, 1964, (2) Kola explosion of Sept. 29, 1996, and (3) Pakistani event of April 28, 1991. The absolute location error associated with this hybrid method is typically comparable to or, in many cases, better than that of the conventional method. Furthermore, this new approach also offers a measurable quantity which positively flags when the location is more likely to be good--even for regions that are not calibrated. These features could have important implications for the CTBT implementation as the proposed algorithm can readily be used in areas previously not well studied as an ad hoc procedure on problem events while the International Monitoring System (IMS) stations are being deployed and calibrated gradually. For local seismic network operators, this algorithm could be an attractive alternative or supplementary location procedure.
