TY - JOUR T1 - Insolation effects on the lunar hydrogen budget; correlated observations of the Lunar Reconnaissance Orbiter's LEND, LOLA and Diviner instruments AN - 1668231483; 2015-027233 AB - In this research we correlate the Lunar Reconnaissance Orbiter's (LRO), Diviner radiometer temperature maps that characterize the Moon's thermal environment with maps derived from the Lunar Exploration Neutron Detector (LEND) and Lunar Orbiting Laser Altimeter (LOLA). In previous research, we found evidence that the Moon's Hydrogen budget was broadly influenced by insolation effects. In that analysis we implemented a transformation of LOLA's topography maps, thereby isolating poleward-facing and equator-facing slopes. We then integrated the LEND epithermal neutron maps over these regions and found that the epithermal neutron count rates were significantly lower in poleward-facing slopes vs. equivalent equator-facing slopes, yielding a localized "epithermal contrast". This result suggests higher H/H (sub 2) O concentrations in poleward-facing slopes vs. comparable equator-facing slopes. It is also consistent with findings in terrestrial and Martian environments indicating similar H/H (sub 2) O slope contrasts. In support of that finding we determined that the epithermal neutron rates over east and west-facing slopes were as predicted equivalent. The above effects were also similar for both North and South Poles. Together, this support indicated surface insolation is an important factor governing the Moon's Hydrogen budget. Temperature effects of insolation are primarily a function of a cosine process a = i cos theta , which predicts the effective solar irradiation a, incident to a given surface as a function of its angular orientation theta , to the source solar irradiation, i. theta is locally a function of several variables including combined: seasonal, diurnal, topographic, latitude and regolith compositional effects which induces locally dependent and time variable temperature conditions. The Moons low obliquity and increased latitude predictably attenuate solar irradiation, which is well correlated with decreased near-surface temperatures towards the poles. Importantly, topographic variance is also a critical factor in theta , that influences a slopes relative orientation to the incident solar irradiation thus inducing localized illumination and temperature conditions. At a given lunar latitude, these factors yield a localized temperature continuum. The temperature differential or 'contrast' between localized poleward-facing and equator-facing slopes approximates the temperature range of this continuum. We extend this research by integrating the Diviner radiometer temperature maps to this analysis. In this effort we will perform a correlative analysis to identify and quantify the temperature contrast between pole-facing and equator-facing slopes used in the LEND analysis. This will allow us to determine the relative contribution of insolation factors e.g. latitude, slope degree and orientation to the poleward direction on epithermal neutron fluences and the Hydrogen budget.

In addition, LRO's objectives included the search for surface resources and the measurement of the lunar radiation environment. After spacecraft commissioning, the ESMD phase of the mission began on September 15, 2009 and was completed on September 15, 2010 when operational responsibility for LRO was transferred to NASA's Science Mission Directorate (SMD). The SMD mission was scheduled for 2 years and completed in September of 2012. Under SMD, the Science Mission focused on a new set of goals related to understanding the history of the Moon, its current state, and what it can tell us about the evolution of the Solar System. Having recently marked the completion of the two-year Science Mission, we will review here the major results from the LRO for both exploration and science and discuss plans and objectives for the Extended Science that will last until September, 2014. Some results from the LRO mission are: the development of comprehensive high resolution maps and digital terrain models of the lunar surface; discoveries on the nature of hydrogen distribution, and by extension water, at the lunar poles; measurement of the daytime and nighttime temperature of the lunar surface including temperature down below 30 K in permanently shadowed regions (PSRs); direct measurement of Hg, H (sub 2) , and CO deposits in the PSRs; evidence for recent tectonic activity on the Moon; and high resolution maps of the illumination conditions at the poles.

The results of observations made by radar onboard the Clementine spacecraft and by neutron (LPNS) and gamma-ray (LPGRS) spectrometers onboard the Lunar Prospector mission have been interpreted as an enhancement of hydrogen abundance in permanently shadowed regions (PSRs) [3]. Unfortunately, the spatial resolution of these instruments were much broader than the size of any largest PSRs [4] requiring model dependent data deconvolution to resolve signal from PSRs itself. Data Analysis: We would like to present updated results of analysis of Lunar Exploration Neutron Detector (LEND) data for about three years of lunar mapping. Data measured by collimated LEND detectors allows one to look at neutron flux distribution at Moon poles with much better spatial resolution then was achieved at previous space missions. Using the LEND data we had tested the hypothesis that all PSRs are contain a large amount of water ice permafrost and test for hydrogen presents in regolith of regions outside of PSRs. Discussion: Both analyses of individual PSRs and studies of groups of PSRs have shown that these spots of extreme cold at lunar poles are not associated with a strong effect of epithermal neutron flux suppression [5]. We found only three large PSRs, Shoemaker and Cabeus in the South and Rozhdestvensky U in the North, which manifest significant neutron suppression, from -5.5% to -14.9%. All other PSRs have much smaller suppression, no more than few percentages, if at all. Some PSRs even display excess of neutron emission in respect to sunlit vicinity around them. Testing PSRs collectively, we have not found any average suppression for them. Only group of 18 large PSRs, with area >200 km (super 2) , show a marginal effect of small average suppression, approximately 2%, with low statistical confidence. A approximately 2% suppression corresponds to approximately 125 ppm of hydrogen taking into account the global neutron suppression near the lunar poles and assuming a homogeneous Hydrogen distribution in depth in the regolith [6].

The LEND data from the polar caps above 80 degree latitude were tested for the presence of local spots of epithermal Neutron Suppression Regions (NSRs) [1, 2]. Six such spots have been found, five at South pole and one at North pole. One of them, NSR S4 in the Cabeus crater, has been suggested, as the best impact site for direct evaluation of the content of lunar volatiles, including the water, by LCROSS instruments [3]. And indeed, a lot of water has been found in the plume, corresponding to 5.6 +/- 2.4 weight % [4]. Another interesting spot NSR S1 is identified with the crater Shoemaker, which PSR perfectly coincides with the contour of the strong neutron suppression. It was shown [5] that there is very good agreement between the profile of the crater depth and the decrease of the flux of epithermal neutrons. Concluding the LEND data analysis of NSRs, one may present two main results: (1) Only two of NSRs are associated with PSRs (Cabeus and Shoemaker), another large PSRs do not manifest a signature of local neutron suppression. (2) There are several NSRs, which have surface illuminated by Sun light. These results could be interpreted by the model of water ice perma-frost, which suggest that NSRs are associated with spots with permanently cold regolith with stable water ice in the porosity volume. In PSRs, the ice bearing layer is the upper most one. If the surface of NSR is periodically illuminated, the ice bearing layer should lie below the top layer of ice-free regolith. During a night, the cold top layer absorbs water molecules from the exosphere (still illuminated nearby hills could be source of these molecules). During a day, the top layer is heated, and water molecules diffuse from the porosity volume into the both directions: upward to exosphere, and downward to the cold layer of permafrost. Such pumping process might depend on local conditions (presence of heated slops nearby, local density of water molecules, depth of permanently cold layer, surface albedo, etc.): therefore, a spot of water ice permafrost might exist in one particular environment, and might not exist in another one. The question should be understood, what is the origin of the water of lunar permafrost. The model has been discussed (i.e. see [5]) that water could be delivered to the Moon by comets. When comets impact with the lunar surface, the vapor of cometary water from the temporal atmospheres condenses at either at temporal or permanent cold traps at poles. Another model has been proposed (i.e. see [5]), which explains the origin of water by chemical reactions between hydrogen of solar wind with oxygen of lunar regolith. The so-called solar water could be produced at the sunlit surface, and than migrate at permanent or temporal cold traps in the local vicinity from the irradiated spot of origin.

These bistatic observations (where the Arecibo Observatory Planetary Radar (AO) transmits a 12.6 cm wavelength signal, which is reflected off of the lunar surface and received by the Mini-RF instrument on LRO) have produced the first lunar non beta-zero radar images ever collected. Rationale: Typically, orbital radar observations use the same antenna to both transmit and receive a signal. The angle between the transmitted and received signals (the bistatic, or beta angle) for these observations is therefore zero, and they are referred to as monostatic observations. By using the AO radar as the transmitter and Mini-RF as the receiver, we have the opportunity to collect data for the Moon with beta angles other than zero. These measurements provide a new and unique test of the water ice hypothesis for the Moon. A common science product produced using planetary radar is the Circular Polarization Ratio (CPR). CPR is the ratio of the powers of received signal in the same sense transmitted divided by the opposite sense. Typical dry lunar surface has a CPR value less than unity. Higher CPR signals can result from multiple-bounce backscatter from rocky surfaces or from the combined volume scattering and coherent backscatter opposition effects (CBOE) from an ice/regolith mixture. The physics of radar scattering predict that high CPR caused by a rocky surface will be relatively insensitive to the beta angle, whilst high CPR caused by ice will be very sensitive to beta, with elevated CPR values dropping off abruptly at beta angles greater than about 1-2 degrees . Mini-RF monostatic data shows many craters with high CPR values. Most of these features are associated with fresh, young craters and display elevated CPR both inside and outside their rims. Some permanently shadowed craters near both poles show elevated CPR inside the crater rims but low CPR outside the crater rim. This has been interpreted as being consistent with RF backscatter caused by surface roughness in the former case and water ice in the latter. We are imaging both po-lar, and non-polar targets that have high monostatic CPR values. By acquiring non beta zero data of equatorial high-CPR regions (which we can safely assume have high CPR due to the presence of surface rocks) we can confirm the hypothesis that high CPR caused by rocks is reasonably invariant to the beta angle. We are looking to see if monostatic high-CPR polar craters have high or low values in the bistatic data. If we find areas that become low only in the bistatic data then this provides strong supporting evidence that these are ice deposits. Using Arecibo and Mini-RF we are acquiring the first ever planetary bistatic radar images at non beta =0 angles. These data provide a unique new piece of evidence to determine if the Moon's polar craters contain ice.

The ability of LOLA to obtain measurements under uniform illumination conditions and in shadowed regions provides an advantage over passive stereoscopic imaging, particularly at high latitudes (> 60 deg) where imaging is hindered by low solar incidence angles. This has allowed LOLA to produce the highest resolution and most accurate polar terrain models to date. However, due to LRO's polar orbit, gaps in the LOLA coverage as wide as approximately 4 km still exist near the equator. Here we present preliminary results of efforts to fill in gaps in LOLA coverage with targeted off-nadir spacecraft slews and by incorporating an independently-derived terrain model into the data post-processing. Recently, the Terrain Camera (TC) aboard the SELENE (Kaguya) spacecraft produced a global digital elevation model (DEM) from stereo imaging with 10-m spatial posting. The TC DEM is a highly complimentary dataset with which to augment the LOLA dataset. We show that the TC DEM can be registered to the LOLA geodetic framework yielding a root-mean-square elevation residual of a few meters. The goal of this work is to produce the most complete global terrain model of the lunar surface by merging both high-resolution datasets while preserving the accuracy of the LOLA data.

During these passages, the RPWS radio system was detecting dust grain impacts, these having peak flux levels within the plumes. We demonstrate that the Langmuir probe electron observations are confirmed by changes in the plasma waves, especially the local upper hybrid frequency. While the increase in plume ions appears anomalous, we present a scenario to explain the large concentrations. We will demonstrate that the observed dropout in electrons is best explained by the presence of a large concentration of submicron grains, and we will then discuss new implications associated with such a collective dusty-plasma system.

The Apollo seismic network has contributed to the internal structure modeling. Efforts have been made to detect the lunar core from the noisy Apollo data (e.g., [1], [2]), but there is scant information about the structure below the deepest moonquakes at about 1000 km depth. On the other hand, there have been geodetic studies to infer the deep structure of the Moon. For example, LLR (Lunar Laser Ranging) data analyses detected a displacement of the lunar pole of rotation, indicating that dissipation is acting on the rotation arising from a fluid core [3]. Bayesian inversion using geodetic data (such as mass, moments of inertia, tidal Love numbers k (sub 2) and h (sub 2) , and quality factor Q) also suggests a fluid core and partial melt in the lower mantle region [4]. Further improvements in determining the second-degree gravity coefficients (which will lead to better estimates of moments of inertia) and the Love number k (sub 2) will help us to better constrain the lunar internal structure. Differential VLBI (Very Long Baseline Interferometry) technique, which was used in the Japanese lunar exploration mission SELENE (Sept. 2007 - June 2009), is expected to contribute to better determining the second-degree potential Love number k (sub 2) and low-degree gravity coefficients. SELENE will be followed by the future lunar mission SELENE-2 which will carry both a lander and an orbiter. We propose to put the SELENE-type radio sources on these spacecraft in order to accurately estimate k (sub 2) and the low-degree gravity coefficients. By using the same-beam VLBI tracking technique, these parameters will be retrieved through precision orbit determination of the orbiter with respect to the lander which serves as a reference. The VLBI mission with the radio sources is currently one of the mission candidates for SELENE-2. We have conducted a preliminary simulation study on the anticipated k (sub 2) accuracy. With the assumed mission duration of about 3 months and the arc length of 14 days, the k (sub 2) accuracy is estimated to be better than 1%, where the uncertainty is evaluated as 10 times the formal error considering the errors in the non-conservative force modeling and in the lander position. We carried out a feasibility study using Bayesian inversion on how well we can constrain the lunar internal structure by the geodetic data to be improved by SELENE-2. It will be shown that such improved geodetic data contribute to narrow the range of the plausible internal structure models, but there are still trade-offs among crust, mantle, and core structures. Preliminary simulation results will be presented to show that the accuracy of core structure estimation will be improved in consequence of better determination of the mantle structure by combining the geodetic data with the seismic data.

It varies with the composition of underlying bedrock, extent of addition of materials excavated by impact both local and distant, and small-scale reworking by micrometeorite bombardment, so it contains information about local geological history. Determining modal mineralogy of soils provides vital ground truth to remote sensing studies. Mineralogy can be determined by a variety of techniques that provide complementary information: X-Ray Diffraction (XRD), optical point counting, element mapping by scanning electron microscopy (SEM) or electron microprobe (EMP), and normative calculation from a bulk chemical analysis. SEM and EMP element mapping can be converted into mineral modal abundances in a variety of ways, including defining compositional windows for specific minerals and using image processing techniques. XRD provides direct determination of the phases present, but gives little information about the chemical composition of those phases. We have launched a project to determine the modal mineralogy of over 100 lunar soils from all Apollo sites. The goal is to use this quantitative mineralogy and laboratory and remote reflectance spectra of the same soils to improve our ability to extract quantitative mineralogy from remote sensing data. Samples (< 1 mm bulk soils) were dry-sieved and the <150 micron fractions analyzed in a Terra XRD instrument (InXitu, Inc.) using sample sizes of approximately 35 mg. We reduced the data using Reitveld refinement as implemented by the Jade program (Materials Data, Inc.). Glass abundances were determined by choosing a linear background and fitting a broad Gaussian to the scattering hump above background. Quantitative XRD is well established, but usually requires some calibration, in spite of the sophisticated Reitveld refinement and whole-pattern fitting. We calibrated the instrument by using mixtures of terrestrial minerals and results from the Lunar Sample Characterization Consortium (data available at web.utk.edu/ approximately pgi/data.html). Without calibration our results differ (though by < 10% relative) from those of the LSCC. Discrepancies may stem from the uncertainties in assigning a pixel to a specific mineral in the SEM point counting approach, not completely randomized orientations of the mineral grains during analysis by Terra, or shock effects in minerals not being taken into account by the Reitveld method. Data for 30 soils from the Apollo 16 site show that on a glass-free basis plagioclase ranges from 78 to 94 wt%, with the sites on the Descartes Mountains (Stations 4, 11, and 13) tending to contain more plagioclase, consistent with previous conclusions that the Descartes highlands are more feldspathic than the Cayley Plains. The relative abundance among mafic silicates varies throughout the site, although the small abundance of the mafic components leads to uncertainty in the Reitveld analysis. Particularly interesting for using the combination of remote sensing and sample measurements is the observation that modal plagioclase is systematically greater than normative plagioclase (normative/modal plagioclase is 0.83 to 0.95). A difference between modes and norms is not unusual, but this substantial difference indicates that the glass in the Apollo 16 regolith is more mafic than the crystalline material, consistent with the average composition of impact glass in Apollo 16 samples compared to bulk soils.

These instruments continuously transmitted data to the Earth until September 1977. Four decades later, the data from the two Apollo sites remain the only set of in-situ heat flow measurements obtained on an extra-terrestrial body. Researchers continue to extract additional knowledge from this dataset by utilizing new analytical techniques and by synthesizing it with data from more recent lunar orbital missions such as the Lunar Reconnaissance Orbiter. In addition, lessons learned from the Apollo experiments help contemporary researchers in designing heat flow instruments for future missions to the Moon and other planetary bodies. For example, the data from both Apollo sites showed gradual warming trends in the subsurface from 1971 to 1977. The cause of this warming has been debated in recent years. It may have resulted from fluctuation in insolation associated with the 18.6-year-cycle precession of the Moon, or sudden changes in surface thermal environment/properties resulting from the installation of the instruments and the astronauts' activities. These types of re-analyses of the Apollo data have lead a panel of scientists to recommend that a heat flow probe carried on a future lunar mission reach 3 m into the subsurface, approximately 0.6 m deeper than the depths reached by the Apollo 17 experiment. This presentation describes the authors' current efforts for (1) restoring a part of the Apollo heat flow data that were left unprocessed by the original investigators and (2) designing a compact heat flow instrument for future robotic missions to the Moon. First, at the conclusion of the ALSEP program in 1977, heat flow data obtained at the two Apollo sites after December 1974 were left unprocessed and not properly archived through NASA. In the following decades, heat flow data from January 1975 through February 1976, as well as the metadata necessary for processing the data (the data reduction algorithm, instrument calibration data, etc.), were somehow lost. In 2010, we located 450 original master archival tapes of unprocessed data from all the ALSEP instruments for a period of April through June 1975 at the Washington National Records Center. We are currently extracting the heat flow data packets from these tapes and processing them. Second, on future lunar missions, heat flow probes will likely be deployed by a network of small robotic landers, as recommended by the latest Decadal Survey of the National Academy of Science. In such a scenario, the heat flow probe must be a compact system, and that precludes use of heavy excavation equipment such as a rotary drill for reaching the 3-m target depth. The new heat flow system under development uses a pneumatically driven penetrator. It utilizes a stem that winds out of a reel and pushes its conical tip into the regolith. Simultaneously, gas jets, emitted from the cone tip, loosen and blow away the soil. Lab experiments have demonstrated its effectiveness in lunar vacuum.

The in-depth analyses of these samples in terrestrial laboratories have yielded profound knowledge that could not have been obtained without the returned samples. While obtaining samples from Solar System bodies is crucial science, it is rarely done due to cost and complexity. Cassini's discovery of geysers on Enceladus and organic materials, indicate that there is an exceptional opportunity and science rational to do a low-cost flyby sample return mission, similar to what was done by the Stardust. The earliest low cost possible flight opportunity is the next Discovery Mission [Tsou et al 2012]. Enceladus Plume Discovery - While Voyager provided evidence for young surfaces on Enceladus, the existence of Enceladus plumes was discovered by Cassini. Enceladus and comets are the only known solar system bodies that have jets enabling sample collection without landing or surface contact. Cassini in situ Findings - Cassini's made many discoveries at Saturn, including the break up of large organics in the plumes of Enceladus. Four prime criteria for habitability are liquid water, a heat source, organics and nitrogen [McKay et al. 2008, Waite et al. 2009, Postberg et al. 2011]. Out of all the NASA designated habitability targets, Enceladus is the single body that presents evidence for all four criteria. Significant advancement in the exploration of the biological potential of Enceladus can be made on returned samples in terrestrial laboratories where the full power of state-of-the-art laboratory instrumentation and procedures can be used. Without serious limits on power, mass or even cost, terrestrial laboratories provide the ultimate in analytical capability, adaptability, reproducibility and reliability. What Questions can Samples Address? - Samples collected from the Enceladus plume will enable a thorough and replicated search for chemical biosignatures to understand the habitability potential of the subsurface ocean of Enceladus [Glavin et al. 2011]. By assessing the chiral excess among different amino acids, identifying chains of amino acids, isolate distinct sequences of these chains and the same for nucleic acids, we can formulate a new set of hypotheses to address some of the key science questions required for investigating the stage of extraterrestrial life at Enceladus beyond the four factors of habitability. Criticality of Analyses - For extraterrestrial organic matter analyses such as chirality and compound-specific isotopes, the repeatable robustness of laboratory measurements is a necessity. These analyses require a series of chemical extraction and derivatization steps prior to analysis that is adapted to the sample and procedures results-driven. The Stardust mission is an excellent example of the challenges in the analysis of organics. Confirmation of the cometary origin of the amino acid glycine from comet Wild 2 was obtained 3 years after the samples were returned to Earth. This long period of laboratory development allowed several modifications to the extraction protocol, multiple analytical techniques and instrumentations.

The Enceladus' plume and dispersed neutral gas produces a large amount of ionized gas, which become a dominant plasma source for Saturn's magnetosphere. A striking feature is that small grains in the plume and in the E ring are negatively charged and electrically couples to the ambient plasma electrically. Cassini Radio and Plasma Wave Science (RPWS) measurements of the cold plasma properties observed a large ion and electron density difference (Ne/Ni < 0.01-0.5) that is associated with the micro-meter sized dust grains near Enceladus plume and the E ring region. At the same time the ion bulk speed is slowed down to near to the Keplerian speed. The conditions are such that rd << dg << D, where rd, dg and D are the typical grain radius, the inter-grain distance and the plasma Debye length, respectively, a so called "dusty plasma". Large ion and electron density differences (Ne/Ni < 1) can be actually found not only near the Enceladus plume but also in a wide area around Saturn's E ring and the plasma disc. To investigate if the charged dust is collectively coupled to the background plasma (i.e., the dusty plasma state), the electric potential of the dust is an important parameter. We use the RPWS/LP data to statistically investigate the dust electrical potential near the E ring. We will present the characteristics of the dust electric potential and discuss the dust-plasma interaction in the E ring and the plasma disc.

The exosphere is the interface between the planet's surface and the surrounding space environment. Its composition and structure are controlled by interactions among the surface, magnetosphere, solar wind, sunlight, and impacting meteoroids. When species are liberated from the surface with sufficient energy, they can be accelerated by solar radiation pressure to form an anti-sunward tail. During three flybys en route to orbit, the Ultraviolet and Visible Spectrometer (UVVS) channel of the Mercury Atmospheric and Surface Composition Spectrometer (MASCS) aboard MESSENGER discovered Mg in the tail and detected Ca+ in a narrow region centered approximately 2.5 Mercury radii anti-sunward of the planet's terminator. UVVS began routine orbital observations of both the dayside and nightside exosphere on March 29, 2011. It regularly measures altitude profiles for all previously detected neutral species with the exception of He and K. The former has no emission features within the UVVS wavelength range (115-600 nm), and the latter has only one relatively weak feature there. A single component of Ca is usually observed at lower altitudes ( approximately 2000 km) and exhibits the strong equatorial, dawn enhancement observed during the flybys. Mg distributions exhibit two components. The more energetic component has been detected at high altitudes, up to 4000 km above the surface on both the dayside and nightside, and shows a dawn enhancement similar to Ca. Dayside distributions of Na exhibit two components with e-folding heights comparable to profiles above the poles obtained during the third flyby. Concentrations of all three species exhibit seasonal variability. The best studied of these is Na, for which maximum dayside density occurs at a Mercury true anomaly angle of 180 degrees . UVVS also observes H. It is less well studied than Ca, Mg, and Na because signal from the exospheric H is often contaminated by emission from interplanetary hydrogen and sunlight reflected from the surface. O has also been detected near the subsolar point, but its emission is too weak for routine study. UVVS observations also include wavelength scans for neutral species that are known or are predicted to be present in the surface materials (e.g., Si, Al, S, Mn, Fe, and OH), but emissions from these species are not sufficiently bright for detection with current operational scenarios. The UVVS team uses a variety of techniques to relate exosphere composition and structure to source processes, including tomographic inversion and Monte Carlo modeling. Correlations of Mercury's neutral exosphere composition and structure with direct measurements of the space environment from MESSENGER's Magnetometer (MAG) and Energetic Particle and Plasma Spectrometer (EPPS) provide further insight into source processes.

We have reported [Neumann et al., 2012, LPSC, #2651] the presence of MLA-dark deposits coinciding with many of the radar-bright regions thought to indicate the presence of subsurface ice. Thermal models [Paige et al., 2012, LPSC, #2875] suggest that at certain latitudes, maximum temperatures exceed the regime of stability of surface water ice, but average subsurface temperatures allow its persistence there against sublimation. At the highest latitudes, where radar signatures fill large portions of polar craters, measurements by MLA are at the noise limit for measuring reflectance; however, several profiles have been obtained with useful energy data. We explore the working hypothesis that dark, complex organics (common in asteroids & comets) overly water ice, providing an important constraint on thermal models of polar regions. Repeated profiles are being acquired in the extended mission in order to more clearly delineate the boundaries of volatile deposits. A good sampling of craters over the appropriate latitude range will further constrain the composition of volatiles. We will report on further mapping in the MESSENGER Extended Mission to the coldest north polar regions, where the majority of ices lie.

We now have approximately five Mercury years of data from orbit. Prior to the MESSENGER mission, Mercury's surface-bounded exosphere was known to contain H, He, Na, K, and Ca. The Ultraviolet and Visible Spectrometer (UVVS) began routine orbital observations of both the dayside and nightside exosphere on March 29, 2011, measuring altitude profiles for all previously detected neutral species except for He and K. We focus here on what we have learned about the sodium exosphere: its spatial, seasonal, and sporadic variation. Observations to date permit delineation of the relative roles of photon-stimulated desorption (PSD) and impact vaporization (IV) from seasonal and spatial effects, as well as of the roles of ions both as sputtering agents and in their possible role to enhance the efficiency of PSD. Correlations of Mercury's neutral sodium exosphere with measurements from MESSENGER's Magnetometer (MAG) and Energetic Particle and Plasma Spectrometer (EPPS) provide insight into the roles of ions and electrons. Models incorporating MAG observations provide a basis for identifying the location and area of the surface exposed to solar wind plasma, and EPPS observations reveal episodic populations of energetic electrons in the magnetosphere and the presence of planetary He+, O+, and Na+.

Measurements of the gravity field and topography made since the MESSENGER spacecraft entered orbit around Mercury in March 2011 can be used to estimate lateral variations in crustal thickness. Mercury Laser Altimeter measurements of topography have yielded a gridded topography model for the northern hemisphere with a grid spacing of approximately 11 km. Doppler tracking of MESSENGER's radio signal for more than 1000 orbits has permitted the determination of a spherical harmonic model of the gravity field of Mercury up to degree and order 50. This model accounts for over 90% of the signal in the observations. However, within the unmodeled signal there are line-of-site (LOS) residuals that are primarily due to the variable spatial resolution of the measurements caused by the highly eccentric orbit of the MESSENGER spacecraft. We estimate variations in crustal thickness with a localized Green's function method and compare our results with crustal thickness estimates derived from a standard spherical harmonic approach. We focus on regions of geophysical interest that are within approximately 30 degrees latitude of MESSENGER's periapsis. First, we perform a local estimation of the Bouguer anomaly by integrating a single-layer Green's function model to calculate the gravity signal at spacecraft altitude from surface topography. We project this Bouguer correction onto the instantaneous line-of-sight direction for differencing with the Doppler signal from the Radio Science Subsystem. We use this difference to invert for the relief on the crust-mantle interface, under the assumptions of no lateral variations in density, a uniform density crust, and an average crustal thickness. We demonstrate the feasibility of this approach with tests that use synthetic gravity data for fully isostatically compensated surface topography, and we examine sensitivity to mean crustal thickness. We find that inversions with LOS residual data and the approach described here can extract the maximum resolution of the crustal thickness estimates from the tracking data.

We first estimated and removed from the observed fields the contributions from Mercury's offset dipole and its magnetopause, cross-tail current, and cusp. Magnetic fields around Mercury are usually organized in coordinate systems defined by magnetic local time (external fields) or planetary longitude (internal fields). Because of Mercury's negligible obliquity, the Z-axes (i.e., perpendicular to the orbital plane or along the rotation axis) for these two systems are almost identical. From the magnetic field residuals organized in magnetic local time, we determine the average vector fields in bins of size 40' by 5 degrees . The minimum limit on remanent magnetization is set by assuming that the Z component of the residual magnetic fields are of external origin, and the maximum limit is set by assuming that those residual fields are of internal origin. The minimum limit is 11 nT at 300 km altitude, and the residuals can be described as a single feature with a center at 74 degrees N, 37 degrees E, in the vicinity of the northern rise of the Mercury's northern volcanic province. This magnetic field is deduced from both the radial and colatitudinal components of the observations, and the two components are consistent with a common source. We are investigating the robustness of this signature with respect to the range of external magnetic fields at Mercury. The spatial scale of the feature is consistent with an origin either in Mercury's crust or as a small-scale feature in Mercury's core field. If the feature originates in Mercury's crust, the field magnitude and the deduced magnetizations are substantially smaller than those associated with the largest crustal magnetic anomalies on Earth, but they are larger than crustal anomalies on the Moon. The maximum limit is substantially larger, but the magnetic fields deduced from the radial and colatitudinal components of the observation are not consistent with a single source. We conclude that most of the fields organized along the Z-axis are of external origin.

Results and interpretations presented here from impact ejecta (Barringer Meteorite Crater), volcanic deposits (Northern Arizona cinders overlying lavas, columnar-jointed Columbia River flood basalts, Hawaii lava flows), and terrains influenced by fluvial-related activity (channeled scablands megaflood bar, Mauna Kea glacio-fluvial deposits) focus on defining the radar "fingerprint" of geologic materials and settings that may be analogous to those found on the Moon and Mars. The challenge in using GPR in geologic investigations is the degree to which different geologic features and processes can be uniquely identified and distinguished in the data. Our approach to constraining this is to qualitatively and quantitatively characterize GPR signatures of different geological environments and to compare them with "ground-truth" observations of subsurface exposures immediately adjacent or subjacent to our GPR transects. Several sites were chosen in each field area based on accessibility, visual access to the subsurface, and presence of particular geologic features of interest. The interpreted distribution of blocks in impact ejecta at Meteor Crater, using a 400 MHz antenna (wavelength of 75 cm) is 1.5-3 blocks per m (super 3) in the upper 1 m (and 0.5-1 blocks per m (super 3) in the upper two meters), which is close to the in situ measured block distribution of 2-3 blocks larger than 0.25-0.30 m per m (super 3) . This is roughly the detection limit to be expected from the lambda /3 resolution approximation of radar wavelength and indicates that the 400 MHz GPR is characterizing the block population in ejecta. While megaflood bar deposits are also reflector-rich, individual reflectors are in general more easily distinguished. At multiple sites, cinders appear smoothly, regularly layered, and allow for excellent GPR penetration. Consequently, the often rough relief of underlying lava flows is discernable, allowing thickness and volume estimates to be made, as well as giving some idea of structure within/on the buried flow. Alternations of massive and clinkery horizons within a'a' flows are detected, as are features representing the interface of overlapping pahoehoe flows (likely due to relatively high relief and fracturing associated with squeeze-ups, etc). Accumulations of gravel, pebbles, and fines derived from lavas and cinders and emplaced by alluvial and mass-wasting processes (along the margins of Apollo Valley, Mauna Kea) appear similar to the pure cinders, as it is likely the same porosity and grain-size characteristics that cause layered GPR reflections. In any case, such layers allow interpretation of how successive events filled in surface relief of the underlying (lava) substrate. GPR data of the interior fill of western Apollo Valley reveals relatively flat reflectors in the along-valley direction and inter-fingering, pinching-out, and dome- and trough-shaped reflectors in the cross-valley direction, indicating accumulation by multiple overlapping lobes coming down the valley, possibly due to multiple fluvial events over time.

Measurements derived from altimetry include crater depth (d), rim height, central peak/ring height, and crater wall/terrace width. Images have been used to derive crater diameter (D) and to assess crater degradation state as well as the nature of any observed impact melt. Analyses of the measurements tie these geometrical parameters to the crater characteristics seen in images. An important first observation is that the freshest craters on Mercury are not necessarily the deepest, as is typically inferred in most studies of d/D ratios. Frequently, the heights of the central peak are also smaller. A good example is provided by a comparison of two peak-ring craters of similar size on Mercury: Atget (D = 102 km) and Hokusai (D = 93 km). Hokusai is extremely fresh and has few superposed craters, broadly extensive craters rays, and distal secondaries. Hokusai also possesses substantial amounts of visible impact melt and evidence for a rampart-like structure reminiscent of ejecta observed on Mars. Although not markedly altered by subsequent impacts, Atget crater is slightly older and more degraded. Atget ejecta show no obvious evidence for melt ponds in the ejecta as seen at Hokusai. The younger Hokusai has a smaller d/D value of 0.022 (d = 2.1 km) than Atget's ratio of 0.032 (d = 3.3 km). In other examples, shallower fresh craters also display a central structure with less relief than comparable but less fresh craters of similar size. The Hokusai-Atget comparison suggests that a shallower depth may be associated with a greater volume of impact melt, but calculations indicate that this increased melt volume is probably not directly responsible for the lesser depth. The observed variation in impact melt volume, as well as the difference in crater depth, could alternatively be the result of differences in impact angle, as has been proposed for craters on the Moon, but no oblique impact-angle morphologies are apparent in the data associated with these and other examples. Structural effects that might be associated with the presence of different central structures, such as a central peak ring, are unlikely to be the cause of the observed depth difference because both Atget and Hokusai have peak rings. Target variations are also unlikely to be important, because both craters are in similar volcanic terrain. The observed greater melt generated at Hokusai than at Atget is best explained by the broad range of impact velocities expected on Mercury, which can range from 15 to 75 km/s. A larger impact velocity will not only generate more impact melt volume, an indicator of higher impact velocity, but from laboratory data a higher velocity will also produce shallower transient craters that can form shallower final craters.

Using these data and coordinated HiRISE images, a approximately 200 m wide and 6.5 km long ridge to the north of a large channel system emanating from Mount Sharp was identified and mapped. The ridge is composed of finely layered strata dipping to the north and exhibits a strong spectral signature of crystalline hematite. To the west, the ridge transitions to an escarpment overlain by younger strata; to the east, debris flows from Mount Sharp cover and obscure the ridge. The ridge is stratigraphically directly above the clay bearing strata. We interpret the ridge to be formed by erosion associated with outflow from the channel that preferentially stripped away flanking strata not as well cemented by hematite. We hypothesize that the hematite accumulated where anoxic groundwater discharged and came into contact with an oxidizing Martian atmosphere. Anoxic water may have originated as precipitation that percolated through the mound, leaching Fe2+ from the overlying sulfate layers until encountering the clay aquiclude. Alternatively, anoxic Fe2+-rich waters at Gale could have originated by groundwater discharge near the base of the mound. In this scenario, dissolved Fe2+ could be leached from an underlying basaltic aquifer or possibly the clay layer. Given that iron oxidation reactions on Earth may be mediated by chemolithotrophic microorganisms, the ridge provides a compelling site for a detailed measurement campaign by the Mars Science Laboratory Curiosity rover.

The IceBreaker drill consists of a rotary-percussive drill head, a sampling auger with a bit at the end having an integrated temperature sensor, a Z-stage for advancing the auger into the ground, and a sampling station for moving the augered ice shavings or soil cuttings into a sample cup. The drill is deployed from a 3 Degree of Freedom (DOF) robotic arm. The drill demonstrated drilling in ice-cemented ground, ice, and rocks at the 1-1-100-100 level; that is the drill reached 1 meter in 1 hour with 100 Watts of power and 100 Newton Weight on Bit. This cor-responds to an average energy of 100 Whr. The drill has been extensively tested in the Mars chamber to a depth of 1 meter, as well as in the Antarctic and the Arctic Mars analog sites. We also tested three sample delivery systems: 1) 4 DOF arm with a custom soil scoop at the end; 2) Pneumatic based, and 3) Drill based enabled by the 3 (DOF) drill deployment boom. In all approaches there is an air-gap between the sterilized drill (which penetrates subsurface) and the sample transfer hardware (which is not going to be sterilized). The air gap satisfies the planetary protection requirements. The scoop acquires cuttings sample once they are augered to the surface, and drops them into an instrument inlet port. The system has been tested in the Mars chamber and in the Arctic. The pneumatic sample delivery system uses compressed gas to move the sample captured inside a small chamber integrated with the auger, directly into the instrument. The system was tested in the Mars chamber. In the third approach the drill auger captures the sample on its flutes, the 3 DOF boom positions the tip of the auger above the instrument, and then the auger discharges the sample into an instrument. This approach was tested in the laboratory (at STP). The above drilling and sample delivery tests have shown that drilling and sample transfer on Mars, in ice cemented ground with limited power, energy and Weight on Bit, and collecting samples in discrete depth intervals is possible within the given mass, power, and energy levels of a phoenix-size lander and within the duration of a phoenix-like mission.

In order to more thoroughly study the MER Mini-Thermal Emission Spectrometer (Mini-TES) and Mars Global Surveyor TES data sets, suites of iron sulfate minerals and phosphate minerals have been collected; the chemistry of each sample has been verified by X-ray diffraction analysis and thermal emission spectra have been obtained. Obtaining pure, well-characterized samples has been arduous, but the spectra to be presented were acquired of chemically verified samples. Iron sulfate and phosphate minerals consist of XO4 tetrahedra (where X is S and P, respectively) polymerized with MO6 polyhedra (where M is a metal cation) in various configurations. These mid-infrared iron sulfate and phosphate spectra are dominated by features associated with the X-O vibrations of the SO4 and PO4 tetrahedra, similar to non-iron-bearing sulfates. Many of the iron sulfate chemistries studied include bound water (OH and/or H2O), hence their iron sulfate spectra exhibit a water bending feature that lies between approximately 1700 and 1630 cm (super -1) . Typically, the phosphate spectra are less hydrous. Within their mineral classes, iron sulfate and phosphate spectra exhibit similarities, which generally align by Strunz groups. These well-characterized spectra will enable further analysis of spectral data sets from Mars.

The Sample Analysis at Mars (SAM) instrument suite on MSL consists of a quadrupole mass spectrometer (QMS), a gas chromatograph (GC), and a tunable laser spectrometer (TLS), which analyze gases created by pyrolysis of samples. During AMASE, a Hiden Evolved Gas Analysis-Mass Spectrometer (EGA-QMS) system represented the EGA-QMS capability of SAM. Another MSL instrument, CheMin, will use x-ray diffraction (XRD) and x-ray fluorescence (XRF) to perform quantitative mineralogical characterization of samples. Field-portable versions of CheMin were used during AMASE. Here we discuss the SAM-like EGA-QMS analyses of a selected subset of samples acquired during several field seasons, together with AMASE CheMin team results. The results enable insight into organic content, organic-mineral associations, and mineralogy. Organic materials evolved from all samples over a range of temperatures. In general, this can indicate that the organics have a range of thermal maturity and/or are bound in different ways to their matrix. Most often, organics that were outside of mineral grains were the dominant pool of organic material inferable from the EGA-QMS, but organics encapsulated within mineral grains, including possibly methane, were also inferred. Organic-mineral associations can influence organic preservation potential and detection. Constraints on these associations, and overall sample organic chemistry, enabled by our SAM-like EGA-QMS analog analyses demonstrate the potential to understand the organic chemical characteristics in materials sampled by MSL, even when utilizing EGA-QMS, the simplest type of solid sample experiment SAM will perform. Any organic chemical information inferred from EGA-QMS analysis could then also be followed by detailed SAM EGA-GCMS and/or EGA-TLS. AMASE analog studies also indicate that SAM EGA-QMS can be expected to support and, in some cases, supplement, CheMin-derived mineralogical analyses of martian surface materials sampled by MSL. Key potential contributions include additional constraints on minor abundances of volatile-bearing minerals or additional insights into the crystallinity of clays or clay mineraloid phases detected. Overall, the types of secondary minerals in a martian assemblage, as well as the nature (e.g., crystallinity) of those phases, can help constrain alteration conditions. Our detailed comparisons between SAM-like and CheMin-like analyses of Mars analogs should provide information that will be directly relevant to interpretation of MSL flight data.

Over the past eight years, the Mars Exploration Rovers (MER) have investigated several outcrops at Meridiani Planum and Gusev Crater. Compared to the MER, the capabilities of Curiosity to investigate outcrops and other deposits are enhanced because the rover incorporates a stand-off laser-induced breakdown spectroscopy (LIBS) instrument within the ChemCam suite. ChemCam's LIBS instrument has the capability to obtain chemical information from a large variety of targets at various distances, up to 7 m, including targets at a distance within stratigraphic layers non-accessible to other payload elements. In this work we demonstrate that semi-quantitative chemical stratigraphy can be very rapidly obtained by performing LIBS measurements on visually distinct layers within an outcrop at a terrestrial Mars analogue: the Atacama Desert, Chile. Such semi-quantitative chemical stratigraphy provides very valuable information on the distribution of elements within the analyzed layers, which can be used for tactical mission planning purposes. We performed laboratory laser-induced breakdown spectroscopy (LIBS) and laser Raman spectroscopy measurement on field samples from a layered outcrop from the Atacama Desert, Chile. This layered outcrop is a good terrestrial morphological analogue for similar formations that will likely be investigated by the Mars Science Laboratory on Gale crater. Our results demonstrate that LIBS can generate semi-quantitative chemical profiles in less than 1 min using automated data processing tools, and therefore the LIBS instrument can become an invaluable tactical tool on MSL for rapid geochemical survey of layered outcrops. The derived chemical profile at the terrestrial analog is consistent with the range of minerals identified by Raman spectroscopy. In the framework of planetary exploration, LIBS can be used during MSL daily tactical operations for rapid geochemical survey of layered outcrops. Morphologically analogous sub-meter layered outcrops exist in Gale crater, and will be potential scientific targets during the MSL mission due to their high relevance to the mission's objectives. On the other hand, a combined Raman/LIBS investigation may provide a rapid mineralogical/chemical evaluation of the target that can be very useful for selecting samples to be eventually collected for sample return purposes or sample sites to be drilled in the search for astrobiology-related species.

Even if this did not happen, prebiotic molecules may have been preserved in the soil, and they might be similar to those that prevailed on the Earth surface some 3.5 to 4 billion years ago. NASA's MSL2011 rover Curiosity will explore the surface and subsurface of Mars, seeking traces of prebiotic or biological activity. Organic signatures are among the main signatures of interest in this frame, and they will be among the main targets of the Gas Chromatograph Quadrupole Mass Spectrometer (GC-QMS) which constitutes the core of the Sample Analysis at Mars (SAM) analytical laboratory, developed by the NASA/GSFC in collaboration with the University of Paris (Fr) and the JPL. The main goal of this instrumentation is indeed to determine molecular abundances and isotopic ratios of organic molecules present in the collected samples, by analyzing gases either sampled from the atmosphere, or obtained from soil processing, either by physical heating or chemical reactions. In order to prepare for the interpretation of the data obtained in situ with the GCQMS of SAM, and due to the complexity of this instrumentation, a number of calibrations are required to determine the exact behavior of each part of this instrumentation, that is required to correctly treat the signal and obtain a correct interpretation of it. In order to prepare the SAM-GC in situ results treatment and interpretation, it is necessary: (1) to determine the instrument ability to detect targets molecules under the instrument operating conditions and (2) to create data bases to help for the identification and quantification of the molecules that could be detected with SAM. With this aim we first selected molecules which might be analyzed with SAM-GC using the following criteria: (1) abundance at the Mars surface (2) astrobiological interest, (3) formation during the sample preparation. Then we characterized these target molecules with laboratory instrumentation using discrete spare components of the GC flight model; in a second step, we used a SAM-GC spare model, in a vacuum chamber roughly reproducing the environmental conditions inside the Curiosity rover. A following step will be to carry out similar experiments with the whole SAM testbed located at the NASA/GSFC. This paper will present an overview of the analytical capabilities of the GC-QMS, with a focus on the GC part, relying on the calibration described previously. In addition, we will present analyses done on Atacama soil samples, Mars soil analog, to get an evaluation of the SAM GC performances with a natural sample.

The archive consists of GNSS, laser ranging, VLBI, and DORIS data sets and products derived from these data. The CDDIS is one of NASA's Earth Observing System Data and Information System (EOSDIS) distributed data centers; EOSDIS data centers serve a diverse user community and are tasked to provide facilities to search and access science data and products. The CDDIS data system and its archive are vital components to many national and international science communities, in particular several of the operational services within the International Association of Geodesy (IAG) and its project the Global Geodetic Observing System (GGOS), including the International DORIS Service (IDS), the International GNSS Service (IGS), the International Laser Ranging Service (ILRS), the International VLBI Service for Geodesy and Astrometry (IVS), and the International Earth Rotation Service (IERS). Several activities are nearing completion at the CDDIS to aid users in data discovery, both within the international space geodesy community and beyond. The CDDIS has completed enhancements to its implementation of the Geodetic Seamless Archive Centers (GSAC). The service provides web services to facilitate data discovery within and across participating archives. The CDDIS is currently implementing modifications to the metadata extracted from incoming data and product files pushed to its archive to permit information about CDDIS archive holdings to be made available through other data portals such as Earth Observing System (EOS) Clearinghouse (ECHO). The CDDIS hopes to soon install an Ntrip broadcast relay to support the activities of the IGS Real-Time Pilot Project (RTPP) and the future Real-Time IGS Service. This poster will include background information about the system and its user communities, archive contents and updates, enhancements for data discovery, new system architecture, and future plans.

Its main objective is to study whether Mars has been habitable at any point of its history. Such studies include the analysis of surficial soils and rocks to understand their mineralogical and chemical make up, additionally, the distribution of hydrogen in the top approximately 30 cm of the surface at some locations of the Gale crater. Mars Odyssey carries a Neutron Spectrometer that has been gathering information for more than a decade. Such information maps the global hydrogen in the top few decimeters of the martian surface and is complementary to the one that will be collected by MSL. Recently, Maurice et al. (2011) has re-analyzed the MONS epithermal data and significantly lowered the statistical systematic uncertainties that plagued previous versions of the data. However, MONS counting-rate data have a FWHM of approximately 550 km, which is sufficiently broad to contain several Gale craters in it. In this study, we choose the PIXON numerical deconvolution technique (Pina 2001, Eke 2001). This algorithm removes the point spread function without introducing spurious features in the presence of noise. We have previously carried out a detailed study of the martian polar regions applying such a methodology to Martian epithermal neutrons near both poles (e.g. Teodoro 2010, 2011) and have been able to reach a resolution of approximately 45 km. In the present study, we will apply this technique to the latest MONS epithermal data at an area centered around the Gale crater.

Titan with energy input from Saturn's magnetosphere, solar UV irradiation, and galactic cosmic rays (GCRs) can make HCN based molecules. Space radiation effects at both moons, and as coupled by the Saturn magnetosphere, could lead to the evolution of biological models at Titan composed of HCNO with oxygen as the new ingredient. The "Old Faithful" model by Cooper et al. (2009) suggests that Enceladus, highly irradiated by Saturn magnetospheric electrons, has episodic ejections of water vapor into Saturn's magnetosphere. At Titan Cassini discovered keV oxygen ions, evidently from Enceladus, bombarding Titan's upper atmosphere (Hartle et al., 2006a,b) and abundant heavy positive and negative ions within Titan's upper atmosphere (Coates et al., 2007). Heavy ion formation in Titan's upper atmosphere can be due polymerization of aromatics such as Benzenes to make polycyclic aromatic hydrocarbons (PAH) (Waite et al., 2007) and/or the polymerization of carbon chains from acetylene to make fullerenes (Sittler et al., 2009). Fullerenes, which are hollow carbon shells, can trap the keV oxygen ions. Clustering of fullerenes, PAHs and PAHNs can form larger aerosols enriched in trapped oxygen which can then precipitate down to Titan's surface. GCRs will chemically process aerosol materials at the surface and provide sufficient energy for processing them into more complex organic forms such as amino acids. We have developed an advanced model of GCR interaction with Titan's atmosphere, surface and sub-surface. This allows one to estimate dose rates at the surface and below and then using laboratory results by Hudson et al. (2008) to estimate abundances of the amino acid such glycene to approximately 100 ppb over time periods relatively short compared to solar system timescales. Therefore, the Saturn system can provide pathways for the accumulation of prebiotic chemicals on Titan's surface.

A series of laboratory experiments was set up to investigate the charge response during repetitive step loading of a suite of dry and saturated rocks. The dry rocks include those with possible semiconductor properties (granite, sandstone, gabbro) and those without (marble, limestone). Saturated samples (gabbro) were prepared by firstly vacuum removing all fluids and gas from open pores, microcracks and fractures and then saturating them for several months with fluids similar to those observed in and around fault zones. Brine with an electrical conductivity matched to that observed in and near fault zones (2 S/m) was obtained by preparing a 0.56 molar NaCl solution. Electrical response from dry rocks during repeated loading cycles from a pedestal stress of 5.6 MPa to 22.7 MPa and back to 5.6 MPa indicates 1) a short-term transient current response of a few tens of pA during loading and unloading with decay time constants of seconds consistent with generation and decay of electrical charge from various alternative physical processes, 2) a net negative current with increasing load in most cases of a few pA or less, and 3) a similar response for rocks with and without semiconductor properties. For the fluid-saturated sample tested, resistance was much lower as expected, and the resistance was increased such that it was on par with the dry sample with a 100 Mohm padding resistor. The baseline was slowly drifting, and continuous currents were observed from self-potential (SP) and electrokinetic effects, but step-loading and unloading produced no observable changes in current generation. This is consistent with self discharge expected in the electrically conductive crust near active faults during tectonic loading. Voltage was also observed to change as a 3 to 4 mV offset from the baseline in the positive direction when stress was applied to the sample.

Researchers have evaluated the spatiotemporal distribution of extreme rainfall and landslides at local and regional scale primarily using in situ data, yet few studies have mapped rainfall-triggered landslide distribution globally due to the dearth of landslide data and consistent precipitation information. This research uses a newly developed Global Landslide Catalog (GLC) and a 13-year satellite-based precipitation record from Tropical Rainfall Measuring Mission (TRMM) data. For the first time, these two unique products provide the foundation to quantitatively evaluate the co-occurence of precipitation and rainfall-triggered landslides globally. The GLC, available from 2007 to the present, contains information on reported rainfall-triggered landslide events around the world using online media reports, disaster databases, etc. When evaluating this database, we observed that 2010 had a large number of high-impact landslide events relative to previous years. This study considers how variations in extreme and prolonged satellite-based rainfall are related to the distribution of landslides over the same time periods for three active landslide areas: Central America, the Himalayan Arc, and central eastern China. Several test statistics confirm that TRMM rainfall generally scales with the observed increase in landslide reports and fatal events for 2010 and previous years over each region. These findings suggest that the co-occurrence of satellite precipitation and landslide reports may serve as a valuable indicator for characterizing the spatiotemporal distribution of landslide-prone areas in order to establish a global rainfall-triggered landslide climatology. This research also considers the sources for this extreme rainfall, citing teleconnections from ENSO as a likely source for regional precipitation variability. This work demonstrates the potential for using satellite-based precipitation estimates to identify potentially active landslide areas at the global scale in order to improve landslide cataloging and quantify landslide triggering at daily, monthly and yearly time scales.

Previous studies on the GNSS-derived ionospheric disturbances have been presented for studying the interactions between ionospheric perturbations associated with the 2011 Japan Tohoku Earthquakes and Tsunamis. Three different types of TIDs were observed. Short-period disturbances (2-8 minutes) with speeds up to 2300 km/s were observed in the near-field, and the long-period (8-22 minutes) disturbances with speeds (195-354 m/s) were identified in both near- and far-fields. In this study, identification and classification of ionospheric disturbances was conducted using a wavelet detection method in combination with a cross-correlation technique estimating the propagation speeds and directions of atmosphere wave-induced disturbances in dual frequency IEC time series collected form GNSS networks near the epicenter of the March 11, 2011 Japan Tohoku earthquake and the subsequent tsunami induced by it. Through the use of the wavelet detection process, we are able to find major wave trains, present in the data collected from these networks, with two dominate frequency bands corresponding to the disturbances from two successive earthquakes and tsunami propagations. Additionally, the comparative observations and model predictions, including ground motions and tsunami propagations calculated by JPL using the MOST model are used to understand and perceive the dominant properties (propagation speeds, directions, periods and occurrence times) of the GPS-derived ionospheric disturbances. This analysis is demonstrated on data from 1235 stations in the Japanese GEONET GPS network. A comparison between GNSS-derived disturbances, ground motions and tsunami propagations shows that the propagation directions and speeds of short-period disturbances are consistent with the acoustic waves triggered by the main-shock and aftershock with different epicenters. The propagation directions and speeds of the long-period disturbances are in agreement with the tsunami propagations.

Their original table has been updated in the latest adopted standards by modifying only a few constituents: four constituents were adjusted for effects of mantle anelasticity and two constituents for effects of ocean tides. We here present a new, consistent, and comprehensive model. While Yoder et al. employed 62 tidal spectral lines, we employ 80, most of the new lines being higher frequency lines that are now detectable, or nearly detectable, in LOD measurements. We employ an anelastic model of Wahr and Bergen consistently to all lines throughout the entire long-period band, although there remains uncertainty in extrapolating to the lowest frequencies. Our model of ocean tides builds on recent experience modeling the fortnightly Mf tide (Ray and Egbert, Geophys. J. Int., 2012), for which good observational data allow extensive testing of both the numerical ocean model and the Wahr-Bergen anelastic model. Ocean model improvements now appear adequate to remove our dependence on data assimilation for Mf (at least for Earth-rotation effects), which is a critical requirement before extending to other frequencies that lack reliable observational constraints. We have run the model for 12 major long-period constituents. The ocean-tide admittance at these 12 frequencies is then interpolated smoothly to all other lines, while relaxing to self-consistent equilibrium for the node tide. Application of this new model to a modern time series of space-geodetic LOD measurements shows a significant reduction in variance compared with the current IERS model. For example, in the 10-70 cpy band, the variance is reduced by 8%.

Primary mission data have been processed at NASA/GSFC using the GEODYN software, resulting in high-resolution (degree and order 420 in spherical harmonics) gravity field models of high accuracy. Here, we present an in-depth analysis of the GRAIL gravity field determination at GSFC. We especially focus on the Ka-band range-rate (KBRR) data, and on the use of GRAIL gravity models on tracking data of other spacecraft. We also investigate to what extent the addition of other tracking data (especially Lunar Prospector data) can help to further enhance the lunar gravity field models. Since the orbit of the GRAIL spacecraft was not constant during the primary mission and sensibly elliptical at the beginning and end of the science phase (20 by 80 kilometers, in altitude above lunar surface), there are areas on the Moon where the spacecraft altitude was relatively low compared to the global average. This results in remaining signal in especially the KBRR data that is not necessarily captured by the global models expressed in spherical harmonics. We explore the performance of the GRAIL gravity field models over certain regions with low-altitude KBRR data, and we also investigate analysis methods to estimate local adjustments to the gravity field models.

Water resources in the region are vital not only for basic human water consumption, but also to support agriculture, energy development, and industrial growth. In this work, we use 10 years of observations from the Gravity Recovery and Climate Experiment (GRACE) satellite mission to evaluate freshwater storage trends in the Asian continent. We calculate the specific trends in crucial river basins by averaging GRACE data into defined river basin boundaries. In addition, we calculate trends in the major groundwater aquifers in the region by combining GRACE data with land-surface model output to isolate the groundwater component of the GRACE signal. Several "hotspots" of water storage decline or increase are also emerging in the Asian continent. Our results illustrate a complex picture of water resources in Asia, and point to the need for a more detailed understanding of the hydrologic dynamics of the region. In particular, improved knowledge of the changes in the Himalayas, which act as the headwaters for the majority of the surface water in the continent and where the changes in glaciers may have profound impacts on downstream water availability, is needed. Finally, this study acts as a snapshot of the trends in Asia's water resources and the broad trends in the region can be used to inform water management and policy decisions to ensure human, food, and energy security in the region.

Skeletal soils that developed long before plants came onto the land would have held water and nutrients in their pore space, yet these resources would have been largely unavailable to primitive, surface-dwelling non-vascular plants due to physical limitations on water transport once the surface layer of soil dries. Plants with roots and a vascular system that could span this dry surface layer could gain increased and prolonged access to the water and nutrients stored in the soil for photosynthesis. Maintenance of the hydraulic connections permitting water to be drawn through the vascular system from deep in the soil to the sites of evaporation in the leaves required a cuticle and physiological regulation of stomata. These anatomical and physiological innovations changed properties of the terrestrial surface (albedo, roughness, a vascular system and control of surface conductance) and set in motion complex interactions of the soil - plant - atmosphere system. We will use coupled physiological and meteorological models to examine some of these interactions.

The twin spacecraft acquired highly precise K Band range-rate (KBRR) intersatellite ranging data and Deep Space Network (DSN) data during this prime mission phase from altitudes of 15 to 75 km above the lunar surface over three lunar months. We have processed these data using the NASA GSFC GEODYN orbit determination and geodetic parameter estimation program, and we have determined gravity fields up to degree and order 420 in spherical harmonics. The new gravity solutions show improved correlations with LOLA-derived topography to high degree and order and resolve many lunar features in the geopotential with a resolution of less than 30 km, including for example the central peak of the crater Tycho. We discuss the methodology used for the processing of the GRAIL data, the quality of the orbit determination on the GRAIL satellites and the derivation of the solutions, and their evaluation with independent data, including Lunar Prospector. We show that with these new GRAIL gravity solutions, we can now fit the low altitude, extended mission Lunar Prospector tracking data better than with any previous gravity model that included the LP data.

The 10-year time-series (since April 2002) of global gravitational potential data are characterized consistently with not only coseismic (episodic) offsets but also postseismic (gradual) relaxation, when localized at the respective area of each earthquake. The recently available Release-05 (RL05) global gravity data (Level-2 data) show ongoing postseismic changes prevailing over other signals and noise, nearly 8 years after the 2004 rupture, and 1 and 2 years after the 2011 and 2010 ruptures, respectively. The abrupt changes in the time-series are consistent with the predicted gravity changes from various seismic solutions, when the centroids locate within the crustal layers (24 km deep or less) with a specific range of compressibility, ruling out the deeper centroid sources. The transient or steady-state changes after all three earthquakes, evident in a decade-long time-series, may imply viscoelastic mantle flow triggered by megathrust ruptures and, ultimately, constrain the asthenosphere rheology and viscosity. For all three megathrust ruptures, the GRACE gravity observations consistently show large-scale interior deformation associated with density change (dilatation). The GRACE observations represent averages over a time window much longer than accessible from seismic data and over a spatial scale much broader than covered by conventional 'geodetic' data. Therefore, GRACE will convey the behavior of the earthquakes on temporal and spatial scales transgressing the seismic and geodetic spectrum. The future GRACE follow-on mission equipped with enhanced instrumentation should allow us to exploit gravitational potential data in the analysis of smaller, and thus more frequent seismic events.

Gravity gradiometry is particularly well suited for identifying discrete structures in the subsurface such as faults cutting across density interfaces and dikes of different density from the host rock. With new high-resolution gravity data from the Gravity Recovery and Interior Laboratory (GRAIL) mission, gravity gradiometry techniques can now be applied to the Moon. We here use the second horizontal derivatives of the lunar potential field derived from GRAIL to investigate the structure of lunar multiring basins. The potential is first separated into surface (terrain, derived from the topography) and subsurface (Bouguer) components. The horizontal gradient tensor is then used to calculate the eigenvalues and eigenvectors, from which the local radial and azimuthal gradients around the basins are calculated. The gradients of the terrain component of the potential field are dominated by the surface expression of the rings, whereas the gradients of the Bouguer component of the potential reveal the presence of ring faults in the subsurface. These subsurface anomalies may arise at the intersection of the faults with either the Moho or an intracrustal density interface separating the upper and lower crust. In many instances, the subsurface expressions of the ring structures in the Bouguer gradients are more prominent than the surface expressions in the terrain gradients. For the Orientale basin, the subsurface expression of ring faults is detected in association with both the Outer Rook and Cordillera rings, supporting a tectonic origin for both rings. The subsurface manifestations of the rings are displaced inward toward the basin center relative to their surface expressions, consistent with the expectation for inward-dipping normal faults. Some contribution to the Bouguer anomalies from dikes intruded along the ring faults is also possible. The spacing between the surface and subsurface expressions of the rings varies widely from one basin to another. These differences can be attributed to either variations in the dip of the ring faults or lateral variations in the vertical density structure of the lunar crust. In addition to the basin rings, a number of large linear anomalies that are not associated with basins are observed in the gravity gradient maps. Four such anomalies are observed with lengths of 500-1000 km, following great circle paths. The Bouguer anomalies and Bouguer gradients associated with the large linear anomalies are consistent with predictions for the gravitational expression of giant dikes or elongated magma chambers. Preliminary analysis has found no surface expression of the large linear anomalies in topographic or image data. We interpret these anomalies as the manifestations of giant dikes, dike swarms, or elongated magma chambers formed early in lunar history. These results demonstrate the utility of gravity gradiometry in planetary applications and reveal new details of the subsurface structure of the Moon.

Anomalies associated with impact craters, from large mascon basins down to crater diameters less than 30 km, are the dominant features of a GRAIL degree (l) 420 free-air gravity map of the Moon. Here we focus on the Bouguer gravity anomalies associated with intermediate-sized craters, in the diameter range of approximately 30-230 km. Results from Apollo-era gravity and topography data analyses suggested that the behavior of crater Bouguer anomalies is age-dependent, but the crater database used then was extremely sparse (12 craters). With the GRAIL gravity field we have a vastly larger set of craters to work with and to date have examined approximately 200 craters. We calculate a finite-amplitude Bouguer correction with a semi-analytical spatial Green's function sampling a spherical harmonic representation of the lunar shape matched to the gravity bandwidth used (l = 2-300). The resulting crater Bouguer anomalies, averaged over the inner part of each crater, fall in a range of approximately -40 to +40 mGal. We compare Bouguer anomalies against lunar age, crater diameter, regional elevation, geographical locale, and geological setting. Results are interpreted in terms of processes that have operated in the lunar crust and upper mantle.

These analyses demonstrate the importance of the volume and depth of impact melting in modifying the interior morphology of large impact craters. At the onset diameter of peak-ring basins, the depth of the basin's melted zone approaches the depth of the transient crater, creating a strengthless interior melt cavity that facilitates gravitational collapse of the transient crater. The melt cavity suppresses central peak formation, and peak rings are formed outward from the melt zone boundary by the interaction of deep-seated rotational faults in the collapsing wall of the transient crater and huge vertical uplifts in the central portions of the basin. The final configuration of the peak-ring basin has a kilometers-thick slab of cooled residual impact melt resting on an uplifted mantle plug with little or no unmelted crustal material. Highly faulted and fractured, dilatant and possibly thickened crust should occur below and outward from the peak ring due to inward and upward translation of collapsed transient crater rim material. As a result of this configuration, the gravity structure should reflect an anomalously high density, uplifted impact melt plus mantle zone spatially confined to within the peak ring. Surrounding this should be a highly fractured, low density zone of possibly thickened crust. Bouguer gravity anomalies derived from Gravity Recovery and Interior Laboratoy (GRAIL) gravity data and Lunar Orbiter Laser Altimeter (LOLA) altimetry data show spatial patterns that are consistent with those predicted by the formation model briefly outlined above. Nearly all 17 peak-ring basins that have been cataloged on the Moon show positive Bouguer gravity anomalies that are spatially confined within the peak ring. The magnitudes of the anomalies are variable, but appear to be less prominent in the smallest peak-ring basins. These observations are consistent with enhanced crustal densities resulting from thinned crust and extreme uplift of the interior melt zone and mantle below. In many of the basins, the annulus between the peak ring and rim crest shows a Bouguer gravity anomaly that is reduced relative to crust exterior to the rim crest. This is consistent with low density, highly faulted and fractured, dilatant crust resulting from the collapse of the transient cavity and formation of the peak ring. The peak rings show gravity anomalies intermediate between the positive central anomaly and reduced gravity annulus, suggesting that peak rings form at the boundary of the uplifted melt plus mantle plug and the zone of highly fractured or thickened crust. Further quantification of the gravity anomalies and comparisons with the predicted density and crustal structure below peak-ring basins will help to better constrain the preliminary observations presented here.

Recent coring (August 2011) in the Coast Range Ophiolite near Lower Lake, CA resulted in the establishment of two sets of reference continental serpentinite cores (to 30 and 42 m depth, respectively) and the installation of eight monitoring wells drawing from different depths. Six of these wells plumb serpentinizing waters, with characteristic high pH (up to 12.5), high calcium loads (10-200 ppm), and methane concentrations that are at or near one-atmosphere saturation, while hydrogen levels are orders of magnitude lower than is typically observed in other similar systems. Low hydrogen levels are cryptic; they may reflect consumption by microbial communities or possibly a pressure- or temperature-related solubility response. Two reference wells provide access to quasi-parallel, shallower groundwater flow regimes with near neutral pH values and surface-related major element and organic acid inventories. Many environmental parameters pertinent to microbiological communities active in serpentinites (such as dissolved hydrogen, methane, and other gas concentrations, redox status, ambient pH, and ionic strength) are largely controlled by host rock mineralogy and, thus, the temperature and progress of serpentinization. Since iron partitioning between co-existing minerals in serpentinites is strongly linked to the evolution of hydrogen (McCollom and Bach, 2009), we report here on mineralogy, bulk geochemistry, and selected mineral chemistry data for the serpentinite cores in order to constrain the production of hydrogen, the dominant bioenergetic driving force in this land-based deep biosphere setting. Parallel microbiological analyses of the same drill cores have shown the predominance of putative hydrogen-oxidizing bacteria. Together these data seek to link the mineralogy of microbial habitats in the serpentinite subsurface to the communities they support, which may have important implication for the study of both active and ancient serpentinizing ecosystems.

However, the habitability of subsurface serpentinizing systems on Mars does not necessarily follow from these qualitative observations. In particular, while the production of H2 during serpentinization could provide methanogens with a needed substrate, the alkaline conditions and corresponding potential for carbon limitation that arise in concert are negatives against which H2 supply must be balanced. We considered this balance via a coupled geochemical-bioenergetic model that weighs the outputs of serpentinization against the metabolic requirements of methanogenesis, in an energetic frame of reference. Serpentinization is modeled using the "Geochemist's Workbench" (GWB) whereby ultramafic harzburgite rocks are reacted with oxygen and sulfate depleted seawater. Reaction kinetics are not explicitly considered, but comparable effects of partial reaction are approximated by assuming post-reaction dilution of equilibrated fluids. The output of GWB serves as the input to the bioenergetic model, which calculates methanogenic energy yields based on spherically-symmetrical diffusion of substrates to a cell followed by reaction at the diffusion-limited rate. Membrane selectivity for substrate transport is explicitly considered. Results will be report updates for two scenarios: (i) High temperature serpentinization followed by cooling and transport of equilibrated fluid to a lower temperature regime accessible to biology; (ii) Serpentinization within the biologically-tolerated range of temperatures. Such coupled models demonstrate that environmental variability with respect to both water-rock reaction, temperature, and biologically-mediated methanogenesis drive orders of magnitude variability in the energy available in methanogenic metabolism.

Field observation of glacial environments is limited by cost and inaccessibility. Optical remote sensing is often precluded by cloud cover and seasonal darkness. Synthetic aperture radar (SAR) overcomes these obstacles by using microwave-frequency electromagnetic radiation to provide high resolution information on large spatial scales and in remote, atmospherically obscured environments. SAR is capable of penetrating clouds, operating in darkness, and discriminating between targets with ambiguous spectral signatures. This study evaluated the efficacy of two SAR Earth observation methods on small (< 7 km2) glaciers in rugged topography. The glaciers chosen for this study lie on Isanotski Volcano in Unimak Island, Aleutian Archipelago, USA. The local community on the island, the City of False Pass, relies on glacial melt for drinking water and hydropower. Two methods were used: (1) velocity field estimation based on Repeat Image Feature Tracking (RIFT) and (2) glacial boundary delineation based on interferometric coherence mapping. NASA Uninhabited Aerial Vehicle SAR (UAVSAR) single-polarized power images and JAXA Advanced Land Observing Satellite Phased Array type L-band SAR (ALOS PALSAR) single-look complex images were analyzed over the period 2008-2011. UAVSAR image pairs were coregistered to sub-pixel accuracy and processed with the Coregistration of Optically Sensed Images and Correlation (COSI-Corr) feature tracking module to derive glacial velocity field estimates. Maximum glacier velocities ranged from 28.9 meters/year to 58.3 meters/year. Glacial boundaries were determined from interferometric coherence of ALOS PALSAR data and subsequently refined with masking operations based on terrain slope and segment size. Accuracy was assessed against hand-digitized outlines from high resolution UAVSAR power images, yielding 83.0% producer's accuracy (errors of omission) and 86.1% user's accuracy (errors of commission). These results represent a refinement of a decades-old entry from the USGS National Hydrography Dataset (NHD). The information gained from this study could strengthen management practices by helping decision makers understand the ecological and economic consequences of glacial change. This procedure could be repeated in similar locations worldwide to provide communities with accurate, quantitative information about their changing glacial resources.

Here, an analysis of the spatial response of the Greenland and Antarctic ice sheets is presented and summarized. Although the modeled responses are not always homogeneous, consistent spatial trends emerge from the ensemble analysis, indicating distinct vulnerabilities of the Greenland and Antarctic ice sheets. There are clear response patterns associated with each forcing, and a similar ice mass loss (or sea-level rise) at the global scale will result in different mass losses at the regional scale. We show that distinct thickness changes occur with each type of external forcing: increased basal lubrication and warmer ocean conditions affect mainly outlet glaciers, while the impacts of atmospheric forcings affect the entire ice sheet.

Ground penetrating radar traces the top of this water table to lie between 8 and 25 m. A radar segment driven over the core sites matches the in situ water depth measurements. Airborne radar data from NASA's Operation IceBridge (OIB) acquired 11 days prior to the ground observations and output of a high-resolution coupled regional atmosphere-firn model are used to outline the horizontal extent, depth and temporal evolution of the water layer. This perennial firn aquifer (PFA) is concentrated in the southern ice sheet areas where snow accumulation rate and melt intensity are high. The estimated mass of retained liquid water for April 2011 is 17 +/- 1 Gt. The PFA represents a new storage mechanism for the ice sheet, and needs to be considered in ice sheet hydrology, mass, and energy budget calculations.

Each of these approaches has various limitations, particularly when applied to less well constrained sectors of the ice sheet. In general, however, the error properties are weakly correlated between methods. Here, we present a mass balance trend estimate for two Antarctic drainage basins, covering part of the Peninsula and Siple Coast, employing a rigorous combination of the three methods. The basins were selected to fully exercise the approach and are for regions where errors due to GIA or sampling are high. The mass balance estimate is derived from a combination of satellite, in-situ and climate model data sets. GRACE mass observations, ICESat altimetry data, GPS bedrock elevation trends, InSAR ice flow velocities as well as precipitation data from the ERA Interim forced regional climate model RACMO for the 2003-2010 period are combined using a data assimilation approach to minimise the error covariances. The dynamic versus accumulation driven contributions to the mass trends over the 7 year period as well as rigorous, consistent uncertainties in the mass trends are resolved. Spatial and temporal error characteristics and sampling limitations are taken into account. Additionally, we provide a solution for GIA that is consistent with all the observations but which requires no assumptions about mantle viscosity or ice sheet history.

For informed decisions on managing these resources sustainably, it is important to have sound assessments of the current state of groundwater resources as well as future predictions. This requires reliable groundwater quantity and quality data. However global access to this data is limited. As part of the GEOSS Water Strategy, the International Groundwater Assessment Centre (IGRAC) is therefore implementing the Global Groundwater Monitoring Network (GGMN). The GGMN facilitates periodic assessments of changes in groundwater quantity and quality by aggregating data and information from existing groundwater monitoring networks and regional hydrogeological knowledge. The GGMN is a participatory process that relies upon contributions from regional and national networks of groundwater experts. Such observation data, along with local well data, surface displacements observed by and GPS data and InSAR, and local in situ gravity data, are necessary for evaluation and simulation of groundwater, leading to improved understanding and prediction of groundwater variations. In conjunction with these observations, regional scale groundwater variations are derived as a residual from land surface-groundwater models through extraction of the total mass of water using geo-rectified Gravity Recovery and Climate Experiment (GRACE) data. Such model-based studies have quantified overdraft and regions at risk of groundwater depletion in parts of Asia, US, and Africa. We provide an overview of these systems, planned missions, and new model-based approaches toward local-scale methods for assimilation of well data for several regions.

The Mars fans date to post-Noachian periods when the martian climate was dominated by cold, hyperarid conditions. Some of the martian fans are differentially eroded to leave their distributary channels in positive relief. This inversion, along with the lack of boulders visible on most fan surfaces, reveals that the dominant grain size of the fans is fine enough for the overbank deposits to be stripped by wind. Degradation, image resolution, and lack of ground truthing all act to obscure the nature of the past flow processes. The fans in the Pampa de Tamarugal of the Atacama Desert of northern Chile are excellent potential Mars analogues for a number of reasons: 1. Hyperaridity, with approximately 2 mm/y rainfall over the fans themselves, resulting in 2. very little vegetation, 3. no fluvial erosion on the fans themselves, and 4. wind-driven erosion of the fan surfaces; 5. equivalent fan scale (tens of km); 6. similar fan gradient (low); 7. low channel branching density; 8. runoff fed from adjacent, much steeper terrain receiving more precipitation ( approximately 500 km (super 2) drainages receiving 0.1-1 m/y precipitation in the High Andes, crater walls and interpreted orographic effects on Mars). Both the modern channels and the preserved stratigraphy are dominated by debris flow-like sheetflow mud deposits. Channels are leveed by concrete-like mass-supported deposits of granules and sand suspended in a silt and clay matrix, often overtopping the channel margins and forming up to 150 m wide levees and km-length sheet flows. This leveeing strongly constrains the aggrading channel, which is typically dominated by better sorted and imbricated fluvial deposits. We infer that the wetter tail of mudlfows sorts the deposits, keeping the central channel unblocked by mud. Relatively few channels are active at any time, but aggradation triggers occasional avulsions. The older, inactive parts of the Atacama fan surface develop partially inverted topography, leaving paleochannels in positive relief. Lack of direct rainfall onto the fan itself means the fan surface is not locally fluvially incised, and the dominant degradation process is aeolian stripping of overbank deposits. Low granular ripples with approximately 1 m spacing are common on the low surfaces, presumably moving by reptation, and part of a partially mobile desert pavement derived primarily from the channel deposits and channel-marginal overbank sediments. Both development of a coarse grain lag on paleochannel ridge crests and cementation of ridge flanks by halite produce the erodability contrast necessary for inversion.

This research uses gridded GRACE Tellus satellite data to quantify changes in total land water storage, including those of groundwater. Global Land Data Assimilation System land components such as soil moisture, canopy moisture, and snow, are subtracted from the GRACE data to isolate the groundwater component. The resulting trends show that most continents are gaining in groundwater storage, which is consistent with GRACE-based estimates of zero-to-increasing changes in total land water. Results indicate a negative contribution to GMSLR for the GRACE time period, which is in contrast to the positive contribution identified in recent studies.

The spatial extent of ground-based investigations can be limited, however, by surficial hot springs, dense foliage, and roadless or private lands. This can result in data gaps in key areas, particularly around active hydrothermal springs. Manned aircraft can provide access to these areas and can yield broad and uniform data coverage, but high-resolution surveys are costly and relatively inflexible to changes in the survey specifications that may arise as data are collected. Unmanned aerial systems (UAS) are well suited for conducting these surveys, but until recently, various factors (scientific instrumentation requirements, platform limitations, and size of the survey area) have required the use of large UAS platforms, rendering unmanned aerial surveys unsuitable for most investigations. We have developed and tested a new cesium magnetometer system to collect magnetic data using two different small-platform UAS that overcomes many of the challenges described above. We are deploying this new system in Surprise Valley, CA, to study the area's active geothermal field. Surprise Valley is ideally suited to testing UAS due to its low population density, accessible airspace, and broad playa that provides ample opportunity to safely land the aircraft. In combination with gravity and topographic data, magnetic data are particularly useful for identifying buried, intra-basin structures, especially in areas such as Surprise Valley where highly magnetic, dense mafic volcanic rocks are interbedded with and faulted against less magnetic, less dense sedimentary rock. While high-resolution gravity data must be collected at point locations on the ground, high-resolution magnetic data can be obtained by UAS that provide continuous coverage. Once acquired, the magnetic data obtained by the UAS will be combined with high-resolution airborne lidar data in order to correlate subsurface structures with subtle surface features, to identify possible conduits for, or barriers to, geothermal fluid circulation. Our September 2012 mission will deploy NASA's SIERRA UAS platform to perform a reconnaissance survey of the entire valley. Results from ground and flight tests indicate that magnetic "noise" from the SIERRA platform is low, and can be effectively compensated to provide data comparable with high-resolution commercial methods. A second mission will be flown in summer 2013 using the SWIFT platform, which will analyze data from its onboard sensors to continuously optimize its flight path in real-time to autonomously investigate regions of interest such as steep magnetic gradients or abrupt changes in anomaly amplitudes and wavelengths. The SWIFT also has the advantage that it can be flown as a glider, further reducing magnetic noise of the platform arising from the engine. This innovative use of UAS and intelligent automation in geophysical investigations offers the ability to obtain higher-resolution and more comprehensive and targeted data at a lower cost than is presently possible, expanding our ability to explore a wide variety of geothermal systems.

Highly sinuous, unconfined meanders require small aspect ratios, which in turn require cohesive channel banks. This cohesion is obtained most commonly by vegetation cover coupled with high suspended sediment loading. The dominant role of vegetation in meandering is reflected in the difficulty in creating highly sinuous channels in flume experiment without introduction of vegetation. The occurrence of strongly meandering channels on Mars suggests meanders can develop in the absence of vegetation. The main objective of our study is to understand the processes of meander evolution in non-vegetated surfaces. We have studied two terrestrial sites in which meandering channels form where vegetation is sparse and has little influence on bank erodibility or point-bar deposition, indicating that there must be other mechanisms creating bank cohesion. One mechanism is stabilization of point-bar deposits by mud drapes. The Quinn River in Nevada is a sinuous channel that flows through fine lacustrine sediments on the floor of paleolake Lahontan resulting in the river having both bed and bank composed of sediment containing least 40% silt/clay. In addition to abundant mud, high salt content of the river water encourages flocculation and settling of fine sediment; thus both high clay/silt content and salt work together at the Quinn River to maintain a small aspect ratio. In contrast to the Quinn River, meandering channels on alluvial fans in the Atacama Desert in northern Chile are deposited by flows originating from the foothills of the Andes Mountains where sediments are coarser and more variable in size. Like Quinn River both fine sediments and salts contribute to meandering. The bank cohesion is provided by mudflows or hyperconcentrated flows creating bank drapes as well as extensive overbank levees which harden to adobe-like consistency. The Atacama Desert is rich in precipitated salts forming salt crusted deposits, and because grains are coarser, we speculate that these salts may possibly be playing a much more direct role in providing the cohesion than they do in the Quinn River. We are using chemical analyses and Scanning Electron Microscope (SEM) images of sediment samples to investigate cementation mechanisms.

However, the physical processes that govern the role of water in basal motion still remain only weakly understood. We instrumented four boreholes at two sites with sensor systems to better understand the processes controlling seasonal flow velocity variations in the marginal zone of the Greenland Ice Sheet. We present measurements of borehole deformation, subglacial water pressure and surface motion during one year (July 2011 to September 2012). Subglacial water pressure and ice deformation show periodic variations on several time scales which are delayed by up to half a period, depending on sensor depth. These observations are interpreted as ice motion in a caterpillar-like fashion, as opposed to the conventionally assumed shear flow. Using a time-dependent, Full-Stokes ice flow model we find that spatially and temporally varying basal motion can explain the observed variations in deformation, and the delayed reaction at different depths. These new data show that the reaction to basal motion is not uniform throughout the ice column, but varies with depth.

While photon-counting systems provide the advantage of using small, low power lasers, they are typically much more susceptible to noise and require the use of sophisticated algorithms both onboard and in ground based processing to ensure capture of valid data and production of accurate data products. An onboard receiver algorithm is being developed for ATLAS to ensure that valid data is returned while adhering to the 577 Gb/day limit on data telemetry. The onboard receiver algorithm makes use of multiple onboard databases, two of which are the DEM (Digital Elevation Model) and the DRM (Digital Relief Map). The DEM provides start and stop times for software-induced range gating on the ATLAS detectors, and is a nested, three-tiered grid to account for a 6 km overall constraint on the allowable limit for ranging acquisition. The DRM contains the maximum values of relief seen across 140m- and 700m-long flight path segments, which are used in statistically determining the presence of a valid surface return and in deciding which bands to telemeter. Both onboard databases are to be primarily constructed from existing digital elevation models and must provide global coverage referenced to latitude and longitude. Production of the grids is complicated by the lack of global data products of sufficient resolution and accuracy such that preliminary analysis is required for DEM selection and usage in addition to the determination of how to intelligently merge differing data sets. This initial investigation is also focused on determining the impact of the selected DEM quality on the ICESat-2 onboard algorithms as well as the precipitated error induced on the DRM. These results are required in order to determine the expected acquisition and downlink protocols. Preliminary accuracy studies using ICESat point elevations indicate that regional accuracy affects the accuracy of the DRM to a greater extent than data resolution, and that the accuracy of the DRM is directly correlated to magnitude of relief. The DEM and DRM grids will have a significant impact on the ability of ATLAS and ICESat-2 to acquire and return valid science data, thus it is imperative that they capture the full range of topography in any given area while still keeping with the telemetry constraints on data volume.

These flows are thought to be mixtures of clasts and melted material that are emplaced during the late stages of impact crater formation. Lunar impact melts have been primarily studied at optical wavelengths, but complementary information can be obtained by observing impact melts at radar wavelengths. Radar data is sensitive to surface and subsurface roughness, and thus can highlight these features even when they are not easily seen in optical data due to burial or imperfect lighting conditions. Impact melts have been identified in radar data on the lunar near side, but they have yet to be studied in depth on the lunar far side, given the lack of global radar data prior to the launch of NASA's Mini-RF instrument on the Lunar Reconnaissance Orbiter (LRO). We have therefore undertaken a global mapping project to identify impact melt flows in the Mini-RF data set. We seek to use this data to determine how the emplacement of melt deposits is influenced by pre-existing topography and impact direction. We have thus far identified fourteen new impact melt flow candidates, ranging in diameter from 2.8 to 37 km, and confirmed these as impact melt in corresponding LRO NAC imagery. Of the known lunar impact melt flows (those reported here combined with those reported in the literature), over 90% of complex crater flows and 55% of simple crater flows have directions that are within 45 degrees of rim crest low. In comparison, only 50% of complex crater flows and 25% of simple crater flows have directions that are within 45 degrees of the downrange direction of impact. This suggests that for many of these melt flows, pre-existing topography plays an important role in final melt flow morphology. This is likely a result of movement during crater modification (complex craters) or a breached crater rim causing melt to escape and flow outwards (simple craters).

Borehole fluid samples obtained via a custom seafloor fluid pumping and sampling system coupled to CORK continuous fluid delivery lines are yielding critical insights into the biogeochemistry and nature of microbial life inhabiting the sediment-covered basement environment. Direct microscopic enumeration revealed microbial cell abundances that are 2-41% of overlying bottom seawater. Snapshots of basement fluid microbial diversity and community structure have been obtained through small subunit ribosomal RNA (SSU rRNA) gene cloning and sequencing from five boreholes that access a range of basement ages and temperatures at the sediment-basement interface. SSU rRNA gene clones were derived from four different CORK installations (1026B, 1301A, 1362A, and 1362B) accessing relatively warmer (65 degrees C) and older (3.5 Myr) ridge flank, and one location (1025C) accessing relatively cooler (39 degrees C) and younger (1.2 Myr) ridge flank, revealing that warmer basement fluids had higher microbial diversity. A sampling time-series collected from borehole 1301A has revealed a microbial community that is temporally variable, with the dominant lineages changing between years. Each of the five boreholes sampled contained a unique microbial assemblage, however, common members are found from both cultivated and uncultivated lineages within the archaeal and bacterial domains, including meso- and thermophilic microbial lineages involved with sulfur cycling (e.g Thiomicrospira, Sulfurimonas, Desulfocapsa, Desulfobulbus). In addition, borehole fluid environmental gene clones were also closely related to uncultivated lineages recovered from both terrestrial and marine hydrothermal systems (e.g. Candidatus Desulforudis, Candidate Phylum OP8) as well as globally distributed marine sediments (e.g. Miscellaneous Crenarchaeotic Group, JTB35). This analysis provides a framework for future research investigating the evolutionary and functional diversity, population genetics, and activity of the poorly understood habitat. These ongoing sampling expeditions greatly benefit from improvements to both CORK observatories and evolving sampling equipment including microbiologically-friendly materials and dependable access to pristine fluids from the ocean crust.

These short-term variations are superimposed on the long-term changes and are of great importance in the determination of the mass balance of the sheets and changes with time from satellite altimetry. Variations in accumulation rate cause changes in mass, while the affects of both accumulation and temperature on firn-compaction do not involve changes in mass and are applied as corrections to observed elevations. Using our time-dependent firn densification model forced by the near three decades (1982-2011) satellite (AVHRR) observed surface temperature and the accumulation rate, approximated by the p-s (precipitation minus sublimation), from ERA-interim, we calculate the corresponding components of the elevation changes over the Antarctica ice sheet. We also calculate the changes driven by the variations in accumulation rate that is based on the sensitivity (5%/K) of the accumulation to temperature changes for comparison. Results show a general warming in the two periods of altimetry measurements (1992-2001 and 2003-2008) over Antarctica, causing approximately 3 mm a-1 decrease in the surface elevation over the ice sheet from enhanced firn compaction. However, the changes driven by the p-s show an overall decrease of 5 mm a-1 and an increase of 3 mm a-1 for the two periods, with striking differences in West Antarctica. With the advantage of the feature in the treatment of accumulation rate impact on the firn compaction in our model, we have separated the correction part in the elevations changes caused by the accumulation rate variation.

We observed the LCROSS impact site at 0.5-second intervals throughout the time of impact in the V-band (491 to 591 nm) using the Agile camera on the 3.5 m telescope at the Apache Point Observatory. Our initial analysis of these images showed that the ejecta plume could be no brighter than 9.5 magnitudes/arcsec (super 2) . (Chanover et al. 2011, JGR). We subsequently applied a Principal Component Analysis (PCA) technique to filter out time-varying seeing distortions and image registration errors from an 8-minute sequence of images centered on the LCROSS impact time and unambiguously detected the evolving plume below the noise threshold. This is the first and only reported image detection of the LCROSS plume from ground-based instruments. Our detection is consistent with an ejecta plume that reaches peak brightness between 12 and 20 seconds after impact and fades to an undetectable level within 90 seconds after impact. This is consistent with in situ observations made by the LCROSS Shepherding Satellite (LCROSS S/SC) and the Lunar Reconnaissance Orbiter (LRO) that observed the impact from above (Colaprete et al., and Hayne et. al., 2010, Science). To test our detection method, we compared the brightness profiles derived from our impact image sequence to those extracted from a sequence with a simulated ejecta pattern. We performed 3-D ballistic simulations of trial impacts, starting with initial particle ejection angles and velocities derived from laboratory measurements made with the NASA Ames Vertical Gun of impacts of hollow test projectiles (Hermalyn et. al., 2012, Icarus). We extracted images from these simulations at 0.5-second intervals, combined them with a computer generated lunar landscape, and introduced image distortions due to time-varying seeing conditions and instrumental noise sources to produce a synthetic ejecta image sequence. We then re-extracted the synthetic plume brightness profiles using the identical PCA filtering algorithm used to detect the LCROSS plume and compared results. With this method, we found that the LCROSS plume reached a peak brightness as viewed from Earth of approximately 9.8 magnitudes/arcsec (super 2) . By varying initial particle ejection angles and velocities in our synthetic plume simulations, we were able to create a family of possible brightness profiles to compare to the detected plume. This comparison yielded constraints on the maximum initial plume particle velocities and ejection angles. We present the results of our LCROSS plume detection and discuss the range of constraints on plume initial conditions implied by our model simulations. These ground-based observations provide a unique and complementary view of the LCROSS impact ejecta compared to that provided by LCROSS S/SC and LRO, which observed the plume from above. This Earth-based data set provides a cross-sectional view and therefore provides unique information necessary to constrain initial conditions of the LCROSS ejecta and, by inference, properties of the lunar regolith on the floor of Cabeus crater.

Past models of the climate of early Earth that utilize paleosol constraints on carbon dioxide struggle to maintain temperatures significantly greater than 0 degrees C. In these models, the incoming stellar radiation is much lower than today, consistent with an expectation that the Sun was significantly fainter at that time. In contrast to these models, many proxies for ancient temperatures suggest much warmer conditions. The surface of the planet seems to have been generally free of glaciers throughout this period, other than a brief glaciation at nearly equal 2.9 billion years ago and extensive glaciation at nearly equal 2.4 billion years ago. Such glacier-free conditions suggest mean surface temperatures greater than 15 degrees C. Measurements of oxygen isotopes in phosphates are consistent with temperatures in the range of 20-30 degrees C; and similar measurements in cherts suggest temperatures over 50 degrees C. This sets up a paradox. Models constrained by one set of geological proxies cannot reproduce the warm temperatures consistent with another set of geological proxies. In this presentation, we explore several potential resolutions to this paradox. First, we model the early Earth under modern-day conditions, but with the lower solar luminosity expected at the time. The next simulation allows carbon dioxide concentrations to increase up to the limits provided by paleosol constraints. Next, we lower the planet's surface albedo in a manner consistent with greater ocean coverage prior to the complete growth of continents. Finally, we remove all constraints on carbon dioxide and attempt to maximize surface temperatures without any geological constraints on model parameters. This set of experiments will allow us to set up potential resolutions to the paradox, and to drive a conversation on which solutions are capable of incorporating the greatest number of geological and geochemical constraints.

Based on analysis of the Gas Chromatography-Mass Spectrometric (GCMS) data through thermal desorption, organic compounds were successfully identified from material samples, such as polymers, paints and adhesives. The library contains the spectra for all the compounds found in each of these analyzed files and is supplemented by a file information spreadsheet, a spreadsheet-formatted library for easy searching, and a Perfluorotributylamine (PFTBA) based normalization protocol to make corrections to SAM data in order to meet the standard set by commercial libraries. An example of the library in use can be seen in Figure 1, where the abundances match closely, the spectral shape is retained, and the library picks up on it with an 88% identification probability. Of course, there are also compounds that have not been identified and are retained as unknowns. The library we have developed, along with its supplemental materials, is useful from both organizational and practical viewpoints. Through them we are able to organize large volumes of GCMS data, while at the same time breaking down the components that each material sample is made of. This approach in turn allows us straightforward and fast access to information that will be critical while performing analysis on the data recorded by the SAM instrumentation. In addition, the normalization protocol dramatically increased the identification probability. In SAM GCMS, PFTBA signals were obfuscated, resulting in library matches far away from PFTBA; by using the normalization protocol we were able to transform it into a 92% probable spectral match for PFTBA. The project has demonstrated conclusively that the library is successful in identifying unknown compounds utilizing both the Automated Mass Spectral Deconvolution & Identification System (AMDIS) and the Ion Fingerprint Deconvolution (IFD) software.

We examine surface and borehole data from the ablation region of the Greenland Ice Sheet to investigate the relationship between water pressure and ice speed. We find that water pressure in boreholes is out of phase with velocities and that water pressure measured in a nearby moulin is in phase with velocities. We explore the possibility that the change of phase between moulin and borehole water pressure is related to two possible processes: 1) diffusion of the pressure wave from the moulin to the borehole sensor (located 150 m away) or 2) sliding near the moulin causes growth of subglacial cavities which permits a pressure drop in the adjacent boreholes.

A diverse range of both Fe/Mg-OH and Al-OH-bearing phyllosilicates were identified including the smectites, nontronite, saponite, and montmorillonite. In order to constrain the abundances of these phyllosilicates spectral analyses of mixtures are needed. We report on our on-going effort to enable the quantitative evaluation of the abundance of hydrated-hydroxylated silicates when they are contained in mixtures. We include two component mixtures of hydrated/hydroxylated silicates with each other and with two analogs for other martian materials; pyroxene (enstatite) and palagonitic soil (an alteration product of basaltic glass). For the hydrated-hydroxylated silicates we include saponite and montmorillonite (Mg- and Al-rich smectites). We prepared three size separates of each end-member for study: 20-45, 63-90, and 125-150 mu m. As the second phase of our effort we used scanning electron microscopy imaging and x-ray diffraction to characterize the grain size distribution, and structural nature, respectively, of the mixtures. Visible and near-infrared reflectance spectra of the 63-90 mu m grain size of the mixture samples are shown in Figure 1. We discuss the results of our measurements of these mixtures.

Recent recognition of a continental-scale rift system cutting the East Antarctic interior indicates that this is incorrect, and has crystallized an alternative view of much more recent geological activity with important implications for tectonic reconstructions and controls on ice sheet formation and stability. The newly defined East Antarctic Rift System appears to extend from at least the South Pole to the continental margin at the Lambert Rift, a distance of 2500 km. This is comparable in scale to the well-studied East African rift system. New analysis of RadarSat data pioneered by Golynsky & Golynsky indicates that further rift zones may extend the East Antarctic Rift System into widely distributed extension zones within the continent. We have carried out a pilot study, using a newly developed gravity inversion technique with existing public domain satellite data, which shows that East Antarctica consists of distinct crustal thickness provinces with anomalously thick areas separated by thin, possibly rifted crust and overall high average thickness. Understanding the nature of crustal thickness in East Antarctica is critical because: 1) Better understanding of crustal thickness in Antarctica, especially along the ocean-continent transition (OCT), will make it possible to improve the plate reconstruction fit between Antarctica, Australia and India in Gondwana and also refine constraints on how and when these continents separated; 2) crustal thickness provinces can be used to aid supercontinent reconstructions and provide new assessments of the influence of basement architecture and mechanical properties on rifting processes; 3) tracking rift zones through East Antarctica will identify the plate-scale geometry of zones of crustal and lithospheric thinning; 4) understanding when and how East Antarctica acquired its thick crust and high elevation, and why it is so thick and elevated, will place new constraints on models of Cenozoic ice sheet formation and stability. The crustal thickness map for East Antarctica will make it possible to produce a multi-dataset-based geothermal heatflux map for the continent. Estimating the heat flux in the Gamburtsev Subglacial Mountains (GSM) region is particularly critical because: 1) The GSM likely acted as key nucleation point for the East Antarctic Ice Sheet (EAIS); 2) the region may contain the oldest ice of the EAIS--a prime target for future ice core drilling; 3) geothermal heat flux is important to understand proposed ice accretion at the base of the EAIS in the GSM and its links to sub-ice hydrology; 4) an integrated multi-dataset-based geothermal heatflux model for East Antarctica will resolve the wide range of estimates previously published using single datasets.

On asteroids, absorptions due to OH in minerals and H2O as ice have been reported in this spectral range by several worker since the 1970s (for instance, [1-5]) With the installation of the SpeX instrument at the NASA IRTF [6], observations of asteroids in the 2-4 mu m region ("LXD mode") are now commonplace. As a result of the ease of observations, a de facto SpeX LXD-mode asteroid survey has been ongoing for the past decade. At this writing, 97 low-albedo asteroids (C complex, D and T asteroids, and low-albedo members of the X complex), which are the focus of this work, have been observed 142 times. Band shapes and classes: A range of 3-mu m band shapes is seen in the asteroid population. Several "Type examples" of the 3-mu m classes have been identified: "Pallas types", with roughly linear band shapes and band minima in the 2.5-2.85 mu m region (where atmospheric water vapor precludes ground-based observations), "Ceres types" with a narrow band centered near 3.05 mu m, and "Themis types" with a broader, rounded absorption near 3.1 mu m. Both Ceres and Themis have had compositional fits made to their spectra [4,12], but while we expect objects with similar spectra to share similar compositions, formal fits to other Ceres- and Themis-type objects remain future work. Takir and Emery find similar band shapes in their sample, though they use different names for their groupings [5]. We are moving toward developing more quantifiable criteria for classifications. One possible approach involves the band depths at 3.2 and 2.9 mu m. When these are plotted against each other, an array of points with similar band shapes but differing band depths is found in both the asteroid data and mineralogical and meteoritical spectra [13,14], all appearing as Pallas types by inspection. In addition to that array, a second cluster of points is found where the 3.2 mu m band depth > or = 2.9 mu m band depth: the non-Pallas types. There is an excellent correlation between the Ch asteroids in the Bus-DeMeo taxonomy and the Pallas types: 29 of 31 Ch objects in the sample are clearly Pallas-types, with the remaining two ambiguous but likely Pallas-types. Future Work: The use of band depth plots shows promise of separating these spectral types from one another, but more work is required to identify the optimal wavelengths. In addition, we have begun exploring the use of principal component analysis (PCA), as has been done for shorter-wavelength data. We also hope to use data from other asteroids and perhaps icy satellites to help guide our analysis.

In this study we report constraints on seasonal, annual and decadal cryospheric changes estimated over the last decade from field, aircraft and satellite measurements and we evaluate the influence of cryospheric changes on the background seismic rate. Multi-year images from the Bering Glacier GFP are available since mid-2003 to constrain changes in extent of the Bering Glacier and to discern feature changes in the glacial surface. Starting around the same time, satellite gravimetric measurements from the Gravity Recovery and Climate experiment (GRACE) commenced. Large spatial-scale mass change calculated from the GRACE mascon solution of Luthcke et al. [2012] indicate a general trend of annual ice mass loss for southern Alaska but with large, variable seasonal mass fluctuations. Since 2007 the station position of a continuous GPS site near Cape Yakataga (Alaska EarthScope PBO site, AB35) has been available as well. In addition to changes in the geodetic position due to tectonic motion, this GPS station shows large seasonal excursions in the detrended vertical and horizontal position components consistent with snow loading in the fall and winter and melt onset/mass decrease in the spring/summer. To better understand the timing of processes responsible for the onset of cryospheric mass loss documented in the GRACE data, we examined changes in the snow cover extent and the onset of melt in the spring. We calculated the elastic displacements of the solid Earth and theoretical earthquake failure criteria associated with these annual and seasonal ice and snow changes. Additionally, we compared the seismic rate (M>1.8) from a reference background time period against other time periods with variable ice or tectonic change characteristics to test the significance of seismic rate changes. Our earlier results suggest statistically significant changes in the background seismic rate associated with large seasonal mass changes.

Pinatubo at southern and northern midlatitudes AN - 1566816109; 2014-077768 AB - Observations have shown that the global mass of nitrogen dioxide decreased at midlatitudes in both hemispheres in the year following the eruption of Mt. Pinatubo, indicating an enhanced heterogeneous chemistry due to the presence of the volcanic aerosol. In contrast, the observed ozone response at southern and northern midlatitudes was largely asymmetrical with respect to the equator, with a general decrease at northern midlatitudes and little change and even a small increase at southern midlatitudes. Simulations including enhanced heterogeneous chemistry but no other direct effects of the volcanic aerosol reproduce a decrease of ozone in both hemispheres, contrary to observations. Our simulations show that the heating due to the volcanic aerosol enhanced both the tropical upwelling and, subsequently, the extratropical downwelling. The enhanced extratropical downwelling, combined with the time of the eruption relative to the phase of the Brewer-Dobson circulation, increased the ozone in the southern hemisphere and counteracted the ozone depletion due to heterogeneous chemistry on volcanic aerosol.

Initial motivation for this project developed from the desire to understand the loss of solar wind volatiles embedded in lunar regolith deposits that were subsequently covered by a lava flow. The Moon lacks a significant atmosphere and magnetosphere, leaving the surface regolith exposed to bombardment by solar flare and solar wind particles, and by the cosmogenic products of galactic cosmic rays. Preservation of particle-rich regolith deposits may have occurred by the emplacement of an active lava flow on top of the regolith layer, provided the embedded particles survive heating by the lava. During future expeditions to the lunar surface, ancient regolith deposits could be sampled through surface drilling to extract the extra-lunar particles, revealing a history of the solar activity and galactic events not available on the Earth. This project also has important implications for terrestrial lava flows, particularly in the prediction of lava flow hazards. Lava erupted on Earth may be emplaced on various substrates, including solid lava rock, volcanic tephra, sands, soils, etc. The composition, grain size, consolidation, moisture content, etc. of these materials will vary greatly and have different effects on the cooling of the flow. Accounting for specific properties of the substrate could be an important improvement in lava flow models We have performed laboratory experiments in collaboration with the Department of Art and Art History at the University of Hawaii at Manoa in which approximately 5-6 kg of basalt, collected at Kilauea Volcano, Hawaii, is melted to approximately 1200 degrees C. The lava is poured into a device constructed of calcium silicate sheeting that has been filled with a solid or particulate substrate material and embedded with thermocouples. Internal temperatures are monitored by the thermocouple array, while external temperatures are monitored by a Forward Looking Infrared Radiometer (FLIR) video camera. The experimental data thus describe the cooling rates of the system, and reveal the release of latent heat of crystallization within the cooling lava. These experiments have been conducted in conjunction with numerical simulations of the heat transfer from a lava flow into various substrates, to quantify the depth reached by the heat pulse as it penetrates the substrate. Models include material-specific, temperature-dependent thermophysical properties, including thermal conductivity, specific heat capacity, and latent heat of crystallization. We find that particulate materials, such as lunar regolith, sand, and soils will be heated to depths shallower than solid materials. In addition, the particulate materials will act as insulators, shielding the lava flow from basal cooling and maintaining high temperatures in the flow core. These results suggest that lava flows emplaced on a dry particulate terrain will remain above solidus for a longer duration, allowing the lava to flow further than when emplaced on a solid substrate.

Nabro (2011) in the UTLS using CALIPSO observations and trajectory mapping AN - 1553089979; 2014-063504 AB - We use cloud-filtered nighttime measurements of scattering ratio from CALIOP, and a Lagrangian trajectory model to study the dispersion of volcanic aerosol from the eruption of Mt. Nabro (Ethiopia/Eritrea) in June 2011. The CALIOP observations show that the volcanic plume reached the low stratosphere within 2 days of the main eruption, with the bulk of material between 380-420K potential temperature. Cloud top brightness temperatures from SEVIRI/Meteosat-9 indicate a direct injection of volcanic material into the low stratosphere from the eruption. AIRS/Aqua measurements show a significant enhancement of SO2 in the plume. Volume depolarization ratios from CALIOP indicate a mixture of ash and newly formed sulfate aerosol. Much of the plume was entrained initially into the Asian summer anticyclone, which extends from the Mediterranean to China. Detrainments from the anticyclone in early July followed two principal transport pathways: (1) westward across the Atlantic, in tropical easterlies, and (ii) eastward across the Northern Pacific in westerly winds, leading to dispersion of the plume throughout Northern mid-latitudes by August. We use our trajectory-mapped analyses of CALIOP data to interpret observations made from ground-based and airborne lidars, and to compute estimates of aerosol optical depth, top-of-atmosphere radiative forcing, and heating profile contributions, associated with the dispersed plume.

The main objectives are to study various characteristic properties of mineral dust, modification in these properties due to long-range transport and mixing with pollution, and to identify dust proxies based on chemical analysis. The duration of campaign witnesses heavy dust storms and the onset of South West Indian Monsoon. AERONET measured Aerosol Optical Depth (AOD) at 500 nm during April to June is observed to vary from 0.2 to 1.2. The aerosol types encountered are classified among Dust, Polluted Dust, Burning, and Continental categories which represent the prevalent aerosol scenario in the region during this period. As reflected in the measured aerosol size distributions, burning generated aerosols have bimodal distribution, whereas Dust and Polluted Dust have trimodal distribution. Based on HYSPLIT calculated 10-day back trajectory analysis, Nepal and the desert regions of NW India are identified as sources of aerosols associated with burning events and dust dominated days respectively. MPLNET derived aerosol extinction profiles show that during dusty days, particles reach up to a height of approximately 5 km. In June and July, surface measured Absorption Coefficient reduced nearly half the value in April and May, while surface measured Extinction Coefficient almost gets doubled. From pre-monsoon to monsoon period, SSA increased from 0.76 to 0.95, while Bext showed three times growth. High values of SSA (Greater than average, 0.83-0.87) are observed on dust events. SEM images of collected aerosol samples show different particle shapes e. g., rhombic, platelets, and parallelepiped. XRF analyses of aerosol samples show the presence of Al, Ti, Fe, Ca, Mg, and K in PM10 samples collected on dust dominated days, and high S content in PM2.5 for burning events. A noticeable characteristic of this analysis is higher Ca/Fe ratio and high K/Al ratio for dust and burning events, respectively. Dominance of SO (sub 4) (super 2-) is observed in ion analysis (Na+, NH4+, K+, Ca2+, Mg2+, Cl-, NO3-, SO (sub 4) (super 2-) ) of the PM2.5 and PM10 samples as per the average concentration.

This enhancement was up to 30% above the mean value or 1 ppmv above the largest value previously observed at these stations. Trajectory analysis traces these events back to a volcanic eruption which took place at Grimsvotn volcano Iceland on 21-28 May 2011. Observations of the initial eruption plume indicated plume top altitudes exceeding 20 km. The eruption of Grimsvotn may have had ample supply of water especially in the early phase of the eruption, due to caldera geothermal water or meltwater from its ice cap. Thus, this moderate Plinian eruption may have injected significant amounts of water vapor well into the stratosphere and may thus be contributing to the source term of stratospheric water vapor. Simultaneous observations of aerosol backscatter at Lindenberg indicate the absence of particles, implying that volcanic particles were injected to this altitude were too large and fell out over the time of transport, or that their concentration was too low. Volcanic injections of water vapor into the lower and middle stratosphere may go unnoticed by observing systems other than in situ observations and may therefore be underestimated due to lack of available data.

The suite of instruments aboard Curiosity will make measurements useful for determining the presence and lateral/vertical distribution of hydrated phases, the mineralogy and "preservation potential" of sediments and rocks, and the identity and isotopic composition of organic and other carbon containing molecules, should such be present. Three of Curiosity's instruments, DAN ("Dynamic Albedo of Neutrons," a soil hydrogen detector), CheMin ("Chemistry and Mineralogy," a mineralogy instrument) and SAM ("Surface Analysis at Mars," an organic molecule and isotopic analysis instrument) are uniquely suited to this purpose. DAN consists of a pulsed neutron generator and neutron detector that will measure the hydrogen content (i.e., hydrated phases, water ice) in the upper meter of the soil. Both passive and active measurements will be obtained, resulting in a meter-scale resolution transect map of near-surface hydrogen along the path of the rover. These measurements will provide context for the mineralogical and organic measurements of drilled and scooped samples analyzed by CheMin and SAM. CheMin, a powder X-ray Diffraction (pXRD) instrument, will determine the mineralogy of scooped soils and powders obtained from drilled rocks. Hydrated minerals will be identified, along with whole-rock mineralogy for characterizing the environment of formation and preservation potential for organic molecules. SAM consists of a sample handling system, a gas chromatograph, a mass spectrometer, and a tunable laser spectrometer. SAM will accept the same powdered rock and soil samples as CheMin, and will measure and identify organic carbon in these samples as well as evolved inorganic gases such as CO2, CH4, and H2O. Isotopic composition of noble gases and several light elements are measured in these gases and in those sampled from the atmosphere. First measurements from these instruments will be obtained subsequent to (and in some cases in concert with) rover commissioning activity tests, during the first 30-60 days of the mission. We anticipate that measurements of subsurface hydrogen from DAN, atmospheric gas measurements from SAM, and mineralogical measurements of the first scooped or drilled surface material will be obtained during this period.

The 155-km diameter Gale Crater was chosen as Curiosity's field site based on several attributes: the interior Mount Sharp preserves a succession of flat-lying strata extending almost 5 km above the elevation of the landing site; the lower few hundred meters of the mound show a progression with relative age from clay-bearing to sulfate-bearing strata, separated by an unconformity from overlying likely anhydrous strata; the landing ellipse is characterized by a mixture of alluvial fan and high thermal inertia/high albedo stratified deposits; and a number of stratigraphically/geomorphically distinct fluvial features. Gale's regional context and strong evidence for a progression through multiple potentially habitable environments, represented by a stratigraphic record of extraordinary extent, ensure preservation of a rich record of the environmental history of early Mars. Curiosity has an expected lifetime of at least one Mars year ( approximately 23 months), and drive capability of at least 20 km. The MSL science payload was specifically assembled to assess habitability and includes a gas chromatograph-mass spectrometer and gas analyzer that will search for organic carbon in rocks, regolith fines, and the atmosphere (SAM); an x-ray diffractometer that will determine mineralogical diversity (CheMin); focusable cameras that can image landscapes and rock/regolith textures in natural color (MAHLI, Mastcam); an alpha-particle x-ray spectrometer for in situ determination of rock and soil chemistry (APXS); a laser-induced breakdown spectrometer to remotely sense the chemical composition of rocks and minerals (ChemCam); an active/passive neutron spectrometer designed to search for water in rocks/regolith (DAN); a weather station to measure modern-day environmental variables (REMS); and a sensor designed for continuous monitoring of background solar and cosmic radiation (RAD; Cruise measurements began on December 6, 2011). The MARDI descent camera is being evaluated for use in the surface mission. The Sample Acquisition, Processing, and Handling (SA/SPaH) subsystem is responsible for the acquisition of rock and soil samples from the Martian surface and the processing of these samples into fine particles that are then distributed to the analytical science instruments (CheMin and SAM). The SA/SPaH subsystem is also responsible for the placement of the two contact instruments (APXS, MAHLI) on rock and soil targets. SA/SPaH consists of a robotic arm and turret-mounted devices on the end of the arm, which include a drill, brush, soil scoop, sample processing device, and the mechanical and electrical interfaces to the two contact science instruments. SA/SPaH also includes two spare drill bits, five organic check material samples, and an observation tray, which are all mounted on the front of the rover, and inlet cover mechanisms that are placed over the SAM and CheMin solid sample inlet tubes on the rover top deck. Recent mission results will be discussed. The first month or two of the mission is designed as a Commissioning Activity Period (CAP) in which each science instrument and rover subsystem is tested in sequence, but done in a fashion that insures science measurements also are obtained.

However, present HSE contents of the Earth's mantle are approximately 3 orders of magnitude higher than that expected by experiments. The apparent over-abundance of HSE has commonly been explained by the addition of meteoritic material in the "late veneer" which describes the exogenous mass addition following the moon forming impact and concluding with the late heavy bombardment at approximately 3.8-3.9 Ga. The strongest evidence for this theory is that the platinum group element (PGE) contents in today's mantle are present in chondritic relative abundances, as opposed to a fractionated pattern expected with metal-silicate partitioning. Archean komatiites indicate that the PGE content of the Earth's mantle increased from about half their present abundances at 3.5 Ga to their present abundances at 2.9 Ga. This secular increase in PGE content suggests a progressive mixing of the late veneer material into the Earth's mantle. However, this time scale also implies that the whole mantle was relatively well mixed by 2.9 Ga. We use a compilation of existing isotopic and trace element data in order to constrain the origin and composition of the late veneer. We use PGE abundances, W abundances and W isotopic compositions in chondritic meteorites and the primitive upper mantle to compute the amount of mass delivered during the late veneer and find the late veneer mass to be approximately 0.6% the mass of the bulk silicate Earth (consistent with earlier estimates). We also use the (super 187) Re- (super 187) Os and (super 190) Pt- (super 186) Os systems to constrain the composition and timing of delivery of the impacting population. We model the efficiency of mantle mixing in this time frame by using 3-dimensional numerical geodynamical simulations and geochemical constraints. Initial parameters include the amount of mass delivered in the late veneer and the Archean internal heating which is at least 4 times higher than the present values, due to the higher abundance of radioactive elements. Another important parameter is the mechanism of mass addition to the Earth. We test three end-member scenarios: (1) a single very large impactor accounting for the entire mass addition, (2) sprinkling of a large number of small impactors over the whole Earth which then mix into the mantle, or (3) by using a size/frequency distribution estimated from the lunar cratering record and corrected for the difference in gravitational cross section of the Earth and the Moon. This project results from collaborations begun at the CIDER II workshop held at KITP, UCSB, 2012.

Curiosity's scientific payload was chosen primarily to allow a geologic and geochemical investigation of Mars' environmental history and habitability, as preserved in the layered sediments on the crater floor and mound. Atmospheric and environmental sensors will contribute by measuring the bulk atmospheric chemical and isotopic composition, the flux of high-energy particle and ultraviolet radiation after modification by the atmosphere, and modern processes related to meteorology and climate over at least one Mars year. The Sample Analysis at Mars instrument will analyze the atmosphere with its mass spectrometer and tunable laser spectrometer. The former is capable of providing bulk composition and isotopic ratios of relevance to planetary evolution, such as nitrogen and noble gases. The latter is designed to acquire high-precision measurements of atmospheric species including CH4, CO2, and H2O, and key isotope ratios in H, C, and O. An important goal will be to compare CH4 abundance and time variability over the mission with the reported detections from the Mars Express orbiter and ground-based observations. The Radiation Assessment Detector (RAD) measures a broad spectrum of high-energy radiation incident at the surface, including secondary particles created via interactions of galactic cosmic rays and solar protons with Mars' atmospheric constituents. Curiosity's Rover Environmental Monitoring Station (REMS) carries six ultraviolet sensors, spanning 200-380 nm. For the first time, both the high-energy and ultraviolet radiation measured at the surface can be compared with measurements above the atmosphere, acquired by other platforms. Modern meteorology and the climatology of dust and water will be studied using the rover's cameras and REMS instrument package. The Mast Cameras are equipped with filters to allow optical measurements of dust and water ice aerosol opacity. Sky images and video clips will illuminate winds (via aerosols) and the dynamics of water ice and dust, including dust devils and dust storms. REMS can measure wind speed and direction in three dimensions, atmospheric pressure, air temperature, ground temperature, and humidity around the clock, independent of the rover's wake/sleep cycles. The meteorological measurements of REMS will be especially interesting given the setting at Gale Crater. Mesoscale modeling of the site indicates a strong influence of the regional topography. As the rover traverses toward Mount Sharp, it will sample different portions of a complex wind field forced by diurnal heating of the surface, ascending and descending catabatic flows from the crater wall and Mt. Sharp, and influences of local variations in albedo, thermal inertia, and topography. The combination of a broad meteorological package, a mobile rover, and a topographically diverse site will provide a wealth of raw data for understanding joint influences of the atmosphere and the surface. For example, orbital imagery indicates active dune migration at the margins of Mt. Sharp. REMS will illuminate the present-day surface stress of winds as a function of position, time, and season. Such correlations are key to understanding the geologic processes that have shaped Mount Sharp and Gale Crater.

A negative temporal trend in accumulation rates is unexpected in light of rising surface temperatures as well as model simulations predicting higher accumulation rates for the region. Both the magnitude of the mean accumulation rates and the range of interannual variability observed in the new records compares favorably to older records collected from a broad area of the West Antarctic ice sheet. The observed negative trend in accumulation is likely the result of a shift in low pressure systems over the Amundsen Sea region, dominated by changes in the austral fall season. Regional-scale climate models and reanalysis data do not capture the strong negative accumulation rate trend observed in these firn cores. Nevertheless the models and reanalyses agree well in both accumulation rate means and interannual variability, with no single model or dataset standing out as significantly more skilled at capturing the observed magnitude of and trend in accumulation rates in this region of the West Antarctic ice sheet.

Here, we employ constraints from experimental partitioning of W between metal and silicate, and from partial melting models, to evaluate the production and preservation of these W isotope anomalies in the Earth's earliest crust. We will also provide a revised interpretation of the Kostomuksha W isotope anomalies based on flow differentiation and metamorphism of komatiites. Two sets of models are produced. Model Set 1: Because D(metal-silicate) for W diminishes with increasing depth, the deep mantle has a higher W abundance, and a lower Hf/W ratio and consequently evolves a negative anomaly in W while the upper mantle evolves a complementary positive anomaly. Subsequent solid-state convection (4.55-2.8 Ga) mixes away the complementary W isotope anomalies to yield the modern mantle null value. This set of models predicts that the complementary negative anomalies in W should eventually be discovered in ancient magmatic rocks of deep mantle origin such as komatiites. Model Set 2: Tungsten is significantly more incompatible (like U, Th and Ba) than Hf, the latter being similar in compatibility to Sm. Our results show that extraction of low-degree partial melts (<2%) leaving a Hadean depleted mantle that can have Sm/Nd approximately 20% higher than chondrites also creates a f(Hf/W) approximately 2-3, sufficient to generate the anomalies observed in Archean rocks. These models increase Hf/W and Sm/Nd ratios in a correlated fashion explaining the tendency of positive W isotope anomalies to occur in rocks with positive Nd isotope anomalies. Recycling of the complementary Hadean crust would result in negative anomalies in later plume lavas, while partitioning of W into an enriched "hidden reservoir" would not. Nd isotope anomalies indicate a melting event around 35-75 Ma after solar system formation, the upper end of which is consistent with our models of Hf/W fractionation, that also yield a depleted mantle composition consistent with DMM. Production of the anomalies is accompanied by the need to preserve the anomalies. We argue that the most effective means of preserving the W isotope anomalies is by crustal storage, and we hypothesize that W is efficiently recycled back to juvenile crust during subduction zone processing. Eventually, the addition of juvenile W from the mantle will dilute the positive W isotope anomalies stored in the early crust. The amount of juvenile W required to be added is about a factor of 4 or more, and it is likely that this occurred during the late Archean crustal growth phase (2.5 Ga), so that positive W isotope anomalies are not likely to occur in much younger rocks. A secular decline in crustal W isotope anomalies is predicted.

Also, the region is highly vulnerable to future climate changes and especially to a drier and windier climate. Estimating the impact of the Sahelian dust on the local and extended area is complicated because the Sahel itself is an active dust source region and it is located downwind of the Sahara, including the Bodele depression. A previous study estimated that emissions driven by strong surface winds occurring across the Sahel significantly contribute to the total dust load over West and North Africa. Another previous study using the ERA-Interim-Reanalysis data concluded that dust emission from the Sahara and subsequent transport of the dust to the Sahel driven by the synoptic patterns is mainly responsible for the formation of the Sahel dust zone. Dust generation in the Sahel is also related to precipitation and human activity. The long-term trend of the Sahelian desert and dust varies depending on analysis methods and periods, and the analyses show either an increasing trend, little change, or a decreasing trend. There is a large gap in models handling the Sahelian dust. A recent review on global dust sources and emission rates indicated that most models do not include emissions from the Sahel. We will present the result of a modeling study on the Sahelian dust using the NASA GOCART model. The dust parameterization has been recently updated with the dynamic source function that utilizes the satellite observed Normalized Difference Vegetation Index. The meteorological fields are taken from the latest version of the NASA GEOS5 system. These recent improvements enable the model to perform more realistic simulations of the Sahelian dust, which has a strong seasonal variation. Specifically our focus in this study is two folds. First, we will attribute the source of dust between the locally emitted dust and the transported dust. Secondly, we will present long-term dust trends in the region produced by the model experiments and compare these model results with observations.

AN - 1323793786; 15567 AB - PURPOSE: Conceptual schemes and schematic alternative approaches for the Constellation Program, which aims to allow humans to travel to the Moon, Mars, and beyond, are proposed. In 2004, President George W. Bush announced the Vision For Space Exploration Initiative to return humans to the Moon by 2020 in preparation for the exploration of Mars and points beyond. As a first step toward developing vehicles to achieve the goals of this initiative, the President directed the National Aeronautics and Space Administration (NASA) to develop and fly a new Crew Exploration Vehicle (CEV, since named Orion) by 2014. The associated program would complete the assessment of requirements and plans to enable CEVs to provide crew transport to the International Space Station and to accelerate the development of the CEV design and crew launch systems. Goals would include: the definition of top-level requirements and configurations for crew and cargo launch systems to support the lunar and Martian exploration programs; development of a reference lunar exploration architecture concept to support sustained human robotic lunar exploration operations; identification of key technologies required to enable and enhance these reference exploration systems; and prioritization of near- and long-term technology requirements. Constellation Program components would be implemented at the Johnson Space Center, Marshall Space Flight Center, Michoud Assembly Facility, and Kennedy Space Center and in as yet undetermined research and development facilities. Areas potentially affected by program activities include Brevard and Volusia counties, Florida; Hanncock County, Mississippi; Orleans Parish, Louisiana; Harris County, Texas; Madison County, Alabama; Cuyahoga and Erie counties, Ohio; Hampton, Virginia; Santa Clara County, California; Dona Ana and Otero counties, New Mexico; and Box Elder and Davis counties, Utah. The Federal Aviation Administration has adopted the final programmatic EIS issued by NASA in January 2008. POSITIVE IMPACTS: The proposed program would develop technology for human and robotic exploration of the Solar System and beyond, and promote international and commercial participation in space exploration. NEGATIVE IMPACTS: Potential building modifications and/or new construction at research and development facilities would result in impacts typical of such projects, largely loss of permeable soil and vegetation. Construction activities would be expected at Michoud Assembly Facility, Kennedy Space Center, and Ames Research Center. New hazardous materials processing facilities would be placed at Kennedy Space Center. Orion thermal protection system flight tests would result in the usual impacts of launching spacecraft. Continued use of substances such as HCFC-141b for thermal protection systems would result in the release of these ozone layer-depleting substances into the atmosphere.

We find that there is good agreement between different satellite methods--especially in Greenland and West Antarctica--and that combining satellite data sets leads to greater certainty. Between 1992 and 2011, the ice sheets of Greenland, East Antarctica, West Antarctica, and the Antarctic Peninsula changed in mass by -152 + or - 49, +14 + or - 43, -65 + or - 26, and -20 + or - 14 gigatonnes year (super -1) , respectively. Since 1992, the polar ice sheets have contributed, on average, 0.59 + or - 0.20 millimeter year (super -1) to the rate of global sea-level rise.

Localized rupturing of the permafrost-capped crust led to voluminous groundwater discharges that carved some of the largest known channels in the solar system. However, our knowledge of the nature of the flows and their ultimate fate remains incomplete, partly because diagnostic landforms at outflow channel termini have been largely destroyed or buried. The Hebrus Valles outflow channels were excavated by fluid discharges that emanated from two point sources, and they mostly terminate in systems of fractures and depressions within the northern plains. Our investigation indicates that outflow channel floodwaters were captured and reabsorbed into the subsurface in zones where caverns developed within the northern plains. These findings imply that the study region comprises the only known location in the Martian northern lowlands where the fate of outflow channel discharges can be assessed with confidence. We propose that evacuation of subsurface materials via mud volcanism was an important process in cavern formation. Our conceptual model provides a hypothesis to account for the fate of sediments and fluids from some of the Martian outflow channels. It also reveals a mechanism for lowland cavern formation and upper crustal volatile enrichment after the development of the Martian global cryosphere.

Interpretations using terrestrial analogs and process mechanics extend our perspective on fluvial geomorphology to another world and offer insight into their formative processes. At the landscape scale, the varied morphologies of Titan's fluvial networks imply a variety of mechanical controls, including structural influence, on channelized flows. At the reach scale, the various morphologies of individual fluvial features, implying a broad range of fluvial processes, suggest that (paleo-)flows did not occupy the entire observed width of the features. DISR images provide a spatially limited view of uplands dissected by valley networks, also likely formed by overland flows, which are not visible in lower-resolution SAR data. This high-resolution snapshot suggests that some fluvial features observed in SAR data may be river valleys rather than channels, and that uplands elsewhere on Titan may also have fine-scale fluvial dissection that is not resolved in SAR data. Radar-bright terrain with crenulated bright and dark bands is hypothesized here to be a signature of fine-scale fluvial dissection. Fluvial deposition is inferred to occur in braided channels, in (paleo)lake basins, and on SAR-dark plains, and DISR images at the surface indicate the presence of fluvial sediment. Flow sufficient to move sediment is inferred from observations and modeling of atmospheric processes, which support the inference from surface morphology of precipitation-fed fluvial processes. With material properties appropriate for Titan, terrestrial hydraulic equations are applicable to flow on Titan for fully turbulent flow and rough boundaries. For low-Reynolds-number flow over smooth boundaries, however, knowledge of fluid kinematic viscosity is necessary. Sediment movement and bed form development should occur at lower bed shear stress on Titan than on Earth. Scaling bedrock erosion, however, is hampered by uncertainties regarding Titan material properties. Overall, observations of Titan point to a world pervasively influenced by fluvial processes, for which appropriate terrestrial analogs and formulations may provide insight.

In this study we used high-resolution topography, geodetic imaging, seismic, and geologic data to advance understanding of how these features evolved during accretion of the Yakutat Terrane to North America. Because glaciers extend over much of the orogen, the topography and dynamics of the glaciers were analyzed to infer the location and nature of faults and shear zones that lie buried beneath the ice. The Fairweather transform fault system terminates by oblique-extensional splay faulting within a structural syntaxis, where thrust faulting and contractional strain drive rapid tectonic uplift and rock exhumation beneath the upper Seward Glacier. West of the syntaxis, oblique plate convergence created a dextral shear zone beneath the Bagley Ice Valley that may have been reactivated by reverse faulting when the subduction megathrust stepped eastward during the last 5-6 Ma. The Bagley fault zone dips steeply through the upper plate to intersect the subduction megathrust at depth, forming a fault-bounded crustal sliver capable of partitioning oblique convergence into strike-slip and thrust motion. Since ca. 20 Ma the Bagley fault accommodated more than 50 km of dextral shearing and several kilometers of reverse motion along its southern flank during terrane accretion. The fault is considered capable of generating earthquakes because it is suitably oriented for reactivation in the contemporary stress field, links to faults that generated large historic earthquakes, and is locally marked by seismicity.

N1 - Last updated - 2012-11-13 ER - TY - JOUR T1 - A Tropospheric Emission Spectrometer HDO/H sub(2)O retrieval simulator for climate models AN - 1257752676; 17425123 AB - Retrievals of the isotopic composition of water vapor from the Aura Tropospheric Emission Spectrometer (TES) have unique value in constraining moist processes in climate models. Accurate comparison between simulated and retrieved values requires that model profiles that would be poorly retrieved are excluded, and that an instrument operator be applied to the remaining profiles. Typically, this is done by sampling model output at satellite measurement points and using the quality flags and averaging kernels from individual retrievals at specific places and times. This approach is not reliable when the model meteorological conditions influencing retrieval sensitivity are different from those observed by the instrument at short time scales, which will be the case for free-running climate simulations. In this study, we describe an alternative, "categorical" approach to applying the instrument operator, implemented within the NASA GISS ModelE general circulation model. Retrieval quality and averaging kernel structure are predicted empirically from model conditions, rather than obtained from collocated satellite observations. This approach can be used for arbitrary model configurations, and requires no agreement between satellite-retrieved and model meteorology at short time scales. To test this approach, nudged simulations were conducted using both the retrieval-based and categorical operators. Cloud cover, surface temperature and free-tropospheric moisture content were the most important predictors of retrieval quality and averaging kernel structure. There was good agreement between the delta D fields after applying the retrieval-based and more detailed categorical operators, with increases of up to 30ppt over the ocean and decreases of up to 40ppt over land relative to the raw model fields. The categorical operator performed better over the ocean than over land, and requires further refinement for use outside of the tropics. After applying the TES operator, ModelE had delta D biases of -8ppt over ocean and -34ppt over land compared to TES delta D, which were less than the biases using raw model delta D fields.

It is shown that an extensive early-time period exists during which the two wakes are individually self-similar with wake widths growing like delta proportional to t super(1/3), as predicted by classical dimensional analysis, but have very different growth rates and are thus not universal. Subsequently, however, the turbulence adjusts to yield, eventually, wakes that are structurally identical and have the same growth rate (also with delta proportional to t super(1/3)) so provide clear evidence of a universal, self-similar state. The former non-universal but self-similar state extends, in terms of a spatially equivalent flow behind a spherical body of diameter d, to a distance of O(3000d) whereas the final universal state does not appear before O(5000d) (and exists despite relatively low values of the Reynolds number and no evidence of a spectral Kappa super(-5/3) inertial subrange). Universal wake evolution is therefore likely to be rare in practice. Despite its low Reynolds number, the flow does not exhibit the sometime-suggested alternative self-similar behaviour with delta proportional to t super(1/2) (as for the genuinely laminar case) at large times (or, equivalently, distances), since the eddy viscosity remains large compared to the molecular viscosity and its temporal variations are not negligible.

Europa's tidally induced fracture patterns, Enceladus's tiger stripes, Ganymede's global expansion induced normal faults, and Io's plain ridges are examples of such tectonic patterns. Given its proximity to Saturn, as well as its eccentric orbit, tectonic features and global stresses may be present on Titan as well. Mountain chains observed on Titan's surface by the Cassini RADAR are of possible tectonic origin. The goal of this study is to create a global map of the orientations of mountain chains on Titan in order to identify the sources of tectonic mechanism. The maps used in this research were constructed with ArcGIS using a low resolution cylindrical base map raster, layered with higher resolution Cassini Visual and Infrared Mapping Spectrometer (VIMS) images and Cassini RADAR swaths from the T3 through T69 flybys. We use RADAR imagery to first map Titan's mountain chains; identifying topographically high surface features by a bright-dark pairing and identifying only mountain chains which are inferred to have been formed through endogenic processes. We then used the data obtained within ArcGIS to construct rose diagrams for mountain chain orientations which were then analyzed and compared with stress models. Lastly, we interpret the geophysical implications of the mountain chains and their orientations in order to present a higher-order picture of tectonism on Titan.

Ridges, the most common tectonic feature on Europa, comprise a central crack flanked by two raised banks a few hundred meters high and each side. Ridges are thought to form along tensile cracks within the ice shell. Dilational bands are usually topographically lower and wider than ridges and display a smooth lineated interior. Some lineaments, ridged bands, have characteristics of both ridges and bands. Together these three classes may represent a continuum of formation in which ridges and dilational bands are end members. A model of ridge formation in which tidal cycling of a crack opens and closes the crack daily, possibly pushing material to the surface and forming a ridge superimposed with a secular dilation of the crack can combine to form the various morphologies described. We will present this model of ridge and band formation, along with an Earth analog from the Antarctic Ross Ice Shelf. Tensile failures in the Ross Ice Shelf exhibit secular dilation, upon which a tidal signal can be seen. From this analog we conclude that the extension model for Europa may be credible and that the secular dilation is most likely from a regional source and not tidally driven.

Interpreting the origin of basin materials requires constraints on the processes controlling basin formation and morphology. Peak-ring basins provide important insight into the basin-formation process, as they are transitional between complex craters with central peaks and multi-ring basins. New image and altimetry data from the Lunar Reconnaissance Orbiter have permitted a reassessment of the origin of lunar peak-ring basins. We synthesize new morphometric observations of lunar peak-ring basins to construct a model for their formation via modification of an interior melt cavity. At the onset diameter of peak-ring basins, the volume and depth of melting are great enough to modify the interior morphology of the basin. The depth of this nested melt cavity is near the transient crater depth, creating a strengthless interior cavity that facilitates gravitational collapse of the transient crater. On the Moon, maximum melting depths are near or exceed the crust-mantle boundary; impact melt in peak-ring basins is thus composed primarily of lower crustal material and some mantle material. Peak rings are formed by the interaction of the inward and upward collapse of the rim of the transient cavity, which uplifts the unmelted base of the excavation cavity. The diameter of the melt cavity is about a factor of five to ten smaller than the current peak-ring diameter, suggesting that peak rings are formed from material uplifted between the edge of the melt cavity and rim of the transient crater. This predicts peak-ring sampling depths much shallower than the maximum depth of melting. The final configuration of the peak-ring basin has a several kilometers-thick slab of cooled impact melt on an uplifted mantle plug with little solid crustal material. Highly faulted and fractured and possibly thickened crust should occur below and outward from the peak ring due to inward and upward translation of collapsed transient crater rim material. This formation scenario has important implications for the interpretation of GRAIL gravity data over basins. The gravity structure should reflect a high density, uplifted impact melt plus mantle zone confined within the peak ring, which is surrounded by a highly fractured, low density zone of possibly thickened crust.

Recent morphologic and morphometric analysis of floor-fractured craters using Lunar Orbiter Laser Altimeter (LOLA) data [Jozwiak et al. 2012] supports the hypothesis that magmatic intrusion and sill formation is a viable mechanism for creating the range of morphologies observed in floor-fractured craters. To further test this hypothesis, we analyze the mechanics of magmatic intrusion and sill formation beneath crater floors. We then make predictions about the magnitude of gravity anomalies that could be associated with both magmatic intrusions and viscously relaxed craters. These analyses allow us to provide predictions for the Gravity Recovery and Interior Laboratory (GRAIL) mission so that this mission can provide definitive distinctions between the two hypotheses. These predictions will allow for direct investigation of the hypothesis that floor-fractured craters are formed by sub-crater magmatic intrusion and sill formation. If an origin for floor-fractured crater formation via magmatic intrusion and sill formation is confirmed, this would provide new constraints on the thermal evolution of the Moon and indicate the presence of widely distributed intrusive volcanism.

From satellite remote sensing, we present here the discovery of the 2012 extreme melt across almost the entire GIS surface. This extreme melt event was first observed from Oceansat-2 satellite scatterometer (OS2) near-real-time data, which was rapidly confirmed by Moderate-resolution Imaging Spectroradiometer (MODIS) and subsequently by Special Sensor Microwave Imager/Sounder (SSMIS) satellite measurements. In-situ temperature data and field observations provided further evidence of the melt event. To obtain the most complete melt detectable across the ice sheet, composite melt maps are produced from the combination of OS2/MODIS/SSMIS with a satellite integration algorithm developed under the NASA Science Innovation Fund for Greenland melt research. Satellite results reveal that melt occurred at or near the surface across 97% of the entire GIS extent on 12 July 2012, including the cold polar areas at high altitudes like Summit in the dry snow facies of the ice sheet. This melt event coincided with an anomalous ridge of warm air that became stagnant over Greenland. As seen in melt layers from the ice core record at Summit reported in the published literatures, such a melt event is rare with the last significant one occurring in 1889 and the next previous one approximately 680 years earlier in the Medieval Warm Period (a.k.a. the Medieval Climatic Anomaly). Compared to the 7-century interval between the previous two events, the 2012 extreme melt occurred only over a century from the 1889 event. In this respect, the 2012 event is considered as a sudden anomaly since the Medieval Warm Period. These significant melt events are widely sporadic in different periods of the Holocene, clearly exhibiting their non-stationary behavior. Regarding the implication on SLR, the change in total GIS mass balance is intricately dependent on competitive changes in mass outflux (e.g., snowmelt, glacier calving) and influx (e.g., snow accumulation). Extreme events of snow accumulation can also be observed by satellite remote sensing. Thus, spatially extensive measurements from multiple satellites are critical to closely monitoring the change in GIS mass balance for an accurate estimation of its contribution to SLR.

AN - 1469621792; 2013-097495 AB - LOLA topography and LOLA-derived crustal thickness data provide evidence for a population of impact basins on the Moon that is likely a factor 2 larger than the classical lists based on photogeology. Frey (2012) determined N(50) crater retention ages (CRAs) for 83 candidate basins > 300 km in diameter by counting LOLA-identified craters superimposed over the whole area of the basins. For some basins identified in topography or model crustal thickness it is not possible to unambiguously identify the crater rim as is traditionally done. Also, Quasi-Circular Depressions (QCDs) > 50 km in diameter are recognizable in the mare-filled centers of many basins. Even though these are not apparent in image data, they likely represent buried impact craters superimposed on the basin floor prior to mare infilling and so should be counted in determining the age of the basin. Including these as well as the entire area of the basins improves the statistics, though the error bars are still large when using only craters > 50 km in diameter. The distribution of N(50) CRAs had two distinct peaks which did not depend on whether the basins were named (based on photogeology) or recognized first in topography or crustal thickness data. It also did not depend on basin diameters (both larger and smaller basins made up both peaks) and both peaks persisted even when weaker candidates were excluded. Burgess (2012, unpublished data) redid the counts for 85 basins but improved on the earlier effort by adjusting the counting area where basins overlap. The two peak distribution of N(50) ages was confirmed, with a younger peak at N(50) approximately 40-50 and an older peak at N(50) approximately 80-90 (craters > 50 km diameter per million square km). We suggest this could represent two distinct populations of impactors on the Moon: one producing an Early Heavy Bombardment (EHB) that predates Nectaris and the second responsible for the more widely recognized Late Heavy Bombardment (LHB).

New altimetry and image data show that the transition from complex craters to peak-ring basins involves morphometric changes that signal the growth and increasing influence of a nested melt cavity; a major manifestation of this is the change from expanding central peak width in complex craters to peak rings that represent the toes of listric wall collapse thrusting inward and upward to the crater floor. Altimetry data permit calculation of Hevelius Formation ejecta thickness decay and volume. Detrended altimetry data reveal buried craters up to the Cordillera ring but not inside the Outer Rook (OR) ring, and ghosts of secondary crater chains that extend up to the OR; these and related data place the approximate final transient cavity rim crest at the 620 km diameter Outer Rook ring, with the Inner Rook representing the peak ring. The knobby Montes Rook Formation (MRF) is interpreted to represent the collapsed transient cavity rim, consisting of the structurally uplifted rim formed from material underthrust from the adjacent transient cavity, and superposed by a huge load of many kilometers of Orientale basin ejecta; during the cavity modification stage, downward and inward translation of the rim at approximately the outer edge of structural uplift formed the Cordillera listric fault ring, causing rotation and translation of the OR Mountains, and the shedding of ejecta outward from the uplifted massifs into the newly formed trough to create the knobby MRF. The inner depression stepdown is interpreted as the surface of a huge cooled impact melt sea, 10-15 km thick and likely to be differentiated. These observations are consistent with a nested melt-cavity basin formation model in which the OR represents the transient cavity, the melt sea represents the collapsed melt cavity, and the peak-ring plateau and MRF represent manifestations of the gravity-driven rotational collapse of the basin rim crest. This model predicts that the nested melt cavity penetrated many tens of km into the mantle, and that basin collapse involved rapid intrusion of a mantle plug into the crust, facilitated by transient shock weakening of deeper crust/mantle material.

Observing Earth from space, with image sets such as Landsat, brings new perspectives to the study of our planet and new ways of solving problems for our communities. The Landsat system originated in 1972, and we now have four decades of Landsat images of Earth that can be used to compare and contrast the effects of geologic processes on our own planet. The treasure trove of Landsat data is now available at no cost, and there is no-cost software to use to study landforms and cities, and to analyze change over time. With Landsat, students from elementary through undergraduate, teachers at all levels, and the general public can see and study the effects of forest fires, assess the health of agricultural fields, monitor the growth of cities, and estimate the extent of future natural disasters such as volcanoes and floods. Elementary through high school science and classroom teachers can easily learn how Landsat images are made and to use the "power in the pixel" with an educational program called "Adopt a Pixel." Formal and informal teachers of all grade levels can download and use Landsat scenes of almost anywhere on Earth, especially their students' own state, region, or town. When terrestrial geological processes and planetary analogs are compared with high-resolution planetary images of other planets, for example the Mars Reconnaisance Orbiter HiRISE images, this type of learning tool can: (1) bring the excitement of solar system exploration to learning about Earth; (2) show ways that our understanding of Earth helps us to interpret and understand data about other planets, and ways that our understanding of other planets has influenced our study of Earth; and (3) look for and monitor indicators of global change on Earth.

To help address this need, the American Museum of Natural History has developed a graduate-level teacher professional development course, Seminars on Science: Climate Change. The 6-week, online-only course covers a broad range of topics, including the fundamentals of the climate system (relevant to earth surface processes); the natural and human causes of climate change; the role of paleoclimate investigations in understanding climate variability; and a discussion of potential consequences and risks of future climate change. An important aspect of AMNH's Seminars on Science: Climate Change is the inclusion of hands-on experience with a full-fledged 3D global climate model (GCM) through a partnership with Columbia University's Educational Global Climate Modeling Project (EdGCM). Through the use of EdGCM, participants are able to work directly with one of the key tools employed in climate change and climate impacts research, an experience that can later be repeated (at appropriate levels of complexity) with their own students. Step-by-step EdGCM exercises walk course participants through the process of simulating climate scenarios and analyzing model output, in a fashion designed to emulate the workflow in scientific research. The EdGCM experience is key to helping the teacher participants to better understand the strengths and limitations of models in climate change research. Together with the other course content, EdGCM provides teachers with the background needed to develop student materials that take a true systems approach to earth science studies. Since AMNH began offering Seminars on Science: Climate Change in 2010, it has become one of the most popular courses offered by the Museum. Although the participants often find the exercises challenging, many report a high level of satisfaction in using EdGCM.

The Moon and Mercury are better able to preserve their most ancient deposits because of their lack of plate tectonics and fluvial and aeolian erosional processes. Knowing the areal extent and spatial distribution of ancient volcanic deposits can aid in our understanding of the thermal history of a planetary body. However, before their spatial extent can be mapped, it is necessary to establish identification criteria in order to distinguish them from non-volcanic plains, such as the lunar light smooth plains deposits formed by impact processes. Studies of the lunar cryptomaria deposits and intercrater plains on Mercury can help to understand and distinguish among the different types of plains units. One important step to understanding the distribution of ancient volcanic deposits is quantifying how ancient terrains fill with volcanic material. Artificial flooding experiments using Lunar Orbiter Laser Altimeter (LOLA) topography data have been conducted on the Moon in heavily cratered terrain and a large basin to determine how they might fill with volcanic material. Map patterns and areal and volume measurements are compared with observed deposits on the Moon and Mercury. Additionally, the Schiller-Schickard region on the Moon represents a lunar analog of the types of stratigraphic relationships possibly present in the intercrater plains on Mercury, because it contains smooth ejecta deposits, maria, and cryptomare deposits. The intercrater plains are among the most heavily cratered terrain on Mercury and are thought to represent an areally substantial series of volcanic resurfacing events. However, some areas mapped as intercrater plains may not have been part of these events and may be impact deposits. Lunar cryptomare identified in the Schiller-Schickard region have likely been formed by Orientale basin ejecta and illustrate relations between volcanic smooth plains and impact-related plains material. Understanding the relationship between these two types of lunar plains materials will aid in understanding the formation of intercrater plains deposits on Mercury.

These basaltic impact breccias were imaged by Opportunity using its 360 degree panoramic cameras. It is proposed that these rocks are examples of the suevite found at Ries Crater in Germany. Suevite is a breccia characterized by angular clasts of rocks and minerals as well as impact glasses, set in a fine-grained matrix. The objective of this study is to understand the processes under which Endeavour crater formed. The area, perimeter, and circularity of the clasts within the Endeavour ejecta were measured and compared to previously published clast measurements from Ries suevite. Preliminary results show the Endeavour clasts are more evenly distributed over all size ranges, whereas the majority of clasts from Ries suevites lie within a narrow range of sizes. The size "sorting" displayed in the Ries suevites and the even distribution of clasts from Endeavour crater may indicate that the Endeavour rocks were part of the ballistic impact deposits in contrast to the fallout suevite.

Because of the chemical similarity of MIs to large granodiorite plutons some have proposed that the plutons represent MIs that stalled in the crust prior to eruption. Intermediate magma is hypothesized to accumulate incrementally until a large, persistent mush (50+% crystals) is developed. Injection of a mafic magma may rejuvenate the mush resulting in eruption of a crystal-rich ignimbrite. If the mush is not rejuvenated, it will fully crystallize as a granodiorite pluton. Zircon U-Pb ages from intrusive suites consistently yield magmatic fluxes of 10 (super -3) - 10 (super -4) km (super 3) /a. In contrast, zircon data for MIs yield fluxes that are at least an order of magnitude greater than plutonic rocks (10 (super -2) km (super 3) /a). Thus, whereas plutons typically preserve a record of zircon crystallization that spans 10 (super 6) -10 (super 7) a, MIs of comparable volume preserve a crystallization record on the order of 10 (super 5) a. This difference might indicate that the hypothesized link between the two rock types is incorrect, or could be a reflection of the proposed difference in their T-t histories. One possibility is that the rejuvenation events inferred to have affected MIs prior to their eruptions dissolved zircon during reheating (e.g., FCT, 715-760 degrees C). However, simulations based on Watson (1996) suggest that even in the favorable case of reheating over 200 ka in a melt with no dissolved Zr, zircons with radii approximately 100 mu m may survive the event. Events with shorter heating timespans and less Zr undersaturation permit much smaller zircons to survive. These results suggest it is unlikely that zircon evidence for multi-Ma mush growth in MIs would be obliterated--a result that is supported by the occurrence of xenocrystic zircon cores preserved in many MIs. We suggest that the difference in age spans between MIs and plutons is related to different magma accumulation rates. Thus, the information recorded by zircon in MIs is indicative of high flux events that favor large eruptions rather than stalling magma in the crust.

A key component of NICE's program model is a commitment to fostering and facilitating a community among our awardees. Recently, we have prioritized the growth of a parallel community of NICE project evaluators. Face-to-face meetings, dedicated webspace for sharing evaluation-related resources, and quarterly webinars allow project evaluators to leverage prior work and incorporate common or useful instruments and tools. We aim to maximize the impact of the funded portfolio through this community of practice, and further through a tri-agency collaboration with sister initiatives at NOAA and NSF. Along with the benefits this community provides to the funded educational and evaluation activities, these efforts also reflect the commitment of NICE and the tri-agency collaboration to government-wide alignment of STEM education activities and evaluations across Federal agencies (e.g., the recommendations of the National Science and Technology Council (NSTC) Committee on STEM Education). Through the formation of a Tri-Agency Common Evaluation Framework working group, these three agencies are involved in coordination of evaluation across the tri-agency portfolio. In April 2012, the working group, comprising representatives of these agencies, the funded projects, and their evaluators, met in Arlington, VA to take early steps in the development of a framework for the common evaluation of this diverse portfolio. The common framework and nascent draft logic model have taken into consideration common evaluation-related needs, the articulation of common goals and desired impacts, and available or needed instruments and/or methodologies in this field. In late October 2012, this framework and the next steps will be discussed in detail by the environmental evaluation community during the American Evaluation Association annual meeting. This talk will describe NICE's efforts to assemble, synthesize, and share climate literacy-focused evaluation instruments, tools, and resources. We'll also report on updates to the efforts of the tri-agency collaboration to establish a common evaluation framework, and on the feedback received from members of the American Evaluation Association.

Yet, it is increasingly important for the public to have a sound scientific understanding of climate and global change decision-making, including uncertainty. Understanding uncertainty is a critical thinking skill and is an element of improved understanding of science. It is important for citizens to consider the limitations of science such that outcomes may have limited predictability. Engaging climate education and communication is a primary role of the U.S. Global Change Research Program (USGCRP), a congressionally mandated consortium of 13 Federal agencies that works to build a sound scientific foundation for global change knowledge, skill, and decision making. The USGCRP strategy for communication, education, and engagement efforts addresses the need for broadening public awareness and understanding of global change through better understanding of citizens' existing knowledge and information needs. The communication and education objectives complement efforts described in other USGCRP strategic goals such as advancing scientific knowledge of the integrated components of the Earth system.

Global Change Research Program; United States ER - TY - JOUR T1 - Thermal behavior of unusual local-scale features on Vesta AN - 1442375735; 2013-079434 AB - On Vesta, the thermal behavior of areas of unusual albedo seen at the local scale can be related to physical properties that can provide information about the origin of those materials. Dawn's Visible and Infrared Mapping Spectrometer (VIR) hyperspectral cubes are used to retrieve surface temperatures and emissivities, with high accuracy as long as temperatures are greater than approximately 180 K. Data acquired in the Survey phase (23 July through 29 August 2011) show several unusual surface features: 1) high-albedo (bright) and low-albedo (dark) material deposits, 2) spectrally distinct ejecta and "pitted" materials, 3) regions suggesting finer-grained materials. Some of the unusual dark and bright features were re-observed by VIR in the subsequent High-Altitude Mapping Orbit (HAMO) and Low-Altitude Mapping Orbit (LAMO) phases at increased pixel resolution. In particular, bright and dark surface materials on Vesta, and pitted materials, are currently being investigated by the Dawn team. In this work we present temperature maps and emissivities of several local-scale features that were observed by Dawn under different illumination conditions and different local solar times. To calculate surface temperatures, we applied a Bayesian approach to nonlinear inversion based on the Kirchhoff law and the Planck function, and whose results were compared with those provided by the application of alternative methods. Data from the IR channel of VIR show that bright regions generally correspond to regions with lower thermal emission, i.e. lower temperature, while dark regions correspond to areas with higher thermal emission, i.e. higher temperature. This behavior confirms that many of the dark appearances in the VIS mainly reflect albedo variations, and not, for example, shadowing. During maximum daily insolation, dark features in the equatorial region may rise to temperatures greater than 270 K, while brightest features stop at roughly 258 K for similar local solar times. However, "pitted" materials, showing relatively low reflectance, have significantly lower temperatures, as a result of differences in composition and/or structure (e.g, average grain size of the surface regolith, porosity, etc.). To complement this work, we provide preliminary values of thermal inertia for some bright and dark features.

As part of the analysis of Vesta's surface composition and geology small morphologically fresh impact craters with distinct ejecta blankets offer the possibility to study more or less unweathered surface material. The ejecta appear bright or dark in the visible light with a sharp contrast to the surrounding region. Mostly, the craters themselves are characterized by a similar albedo. Only a few impact craters show bright ejecta and a dark crater floor [4]. In general, bright ejecta exhibit howardite/eucrite-like spectra with relatively deep pyroxene absorptions near 1 and 2 mu m compared to their surroundings. In the case of dark ejecta the pyroxene absorptions are strongly reduced possibly due to the addition of carbonaceous material. Although, the absorption near 2mu m is barely visible at all, the position of the absorption near 1mu m is similar to the position measured for the bright ejecta, which implies no significant changes in the pyroxene composition. Changes in the pyroxene composition indicated by a shift in the band positions could only be identified in the vicinity of one impact crater characterized by bright ejecta and dark crater material, which is directly located at a huge scarp marking the rim of the Rheasilvia impact basin [4]. Both materials show a pronounced pyroxene signature, even if they have different albedos. The bright ejecta show the typical spectral characteristics as mentioned above. The positions of the pyroxene absorptions measured in the crater and slumping material extending from the crater itself, however, occur at shorter wavelength, more characteristic for diogenitic material, and strengthen the thesis that deeper parts of Vesta's subsurface are of more diogenitic composition [4].

VIR characterizes and maps the mineral distribution on Vesta--strengthening the Vesta HED linkage--and provides new insights into Vesta's formation and evolution (2,3). VIR spectra are dominated by pyroxene absorptions near 0.9 and 2.0 mu m and large thermal emission beyond 3.5 mu m. Although almost all surface materials exhibit howardite-like spectra, some large regions can be interpreted to be richer in eucritic (basaltic) material and others richer in diogenititic (Mg-orthopyroxenitic) material. The Rheasilvia Basin contains Mg-pyroxene-rich terrains for example. Vesta's surface shows considerable diversity at local scales. Many bright and dark areas (3,4) are associated with various geological features and show remarkably different morphology. Moreover, VIR detected statistically significant, but weak, variations at 2.8 mu m that have been interpreted as indicating the presence of OH-bearing phases on the surface (5). The OH distribution is uneven with large regions lacking this absorption feature. Associations of 2.8 mu m band with morphological structures indicate complex process responsible for OH. Vesta exhibits large spectral variations that often correlate with geological structures, indicating a complex geological and evolutionary history, more similar to that of the terrestrial planets than to other asteroids visited by spacecrafts.

Similar features occur in sedimentary rocks all over the world and have been referred to as Liesegang bands. Closer examination reveals that the rocks in each locality are sandstones that host one to 20 mm thick, undulatory bands of iron oxide cement (IOC). The rock between the IOC bands is alternately lightly stained and lacking iron oxide stain (IOS). Both the IOS and IOC crosscut and obscure sedimentary structures. Many of the bands of IOS are arcuate and appear to be truncated by the bands of IOC; mimicking the appearance of cross-stratification. Both the IOC and IOS are related spatially to vertical joints that cut the sandstone at regular intervals. The spacing of bands of IOS is variable but typically follows the Jablczynski spacing law whereas the width of the bands typically increases with distance from a band of IOC. Bands of IOC, on the other hand, exhibit more variable spacing and a weak but significant dependence of band thickness on distance between bands of IOC. The IOS consists of mounds of acicular needles precipitated on quartz grains. The pore-filling IOC comprises both needles and hexagonal plates of iron oxide, but there are also bundles of twisted filaments. At least three filaments occur in each bundle. The bundles are approximately 1 mu m in diameter and 10s of mu m long. The ends of some filaments are anchored to quartz grains. These morphotypes are similar to those exhibited by the microaerophilic iron-oxidizing bacteria Gallionella. We interpret the IOC to be produced by microbially-mediated dissolution of siderite and oxidation of ferrous iron. Iron-oxidizing bacteria colonized the redox interface between siderite-cemented sand and porous sandstone. Microbes oxidized aqueous Fe(II), generating acid that caused siderite dissolution. Bands of IOS largely retain the morphology of reaction fronts, presumably as a result of differential adsorption of aqueous Fe(II) during siderite dissolution. Variations in the width of bands of IOS and in the spacing between these bands is evidence that the IOS is a part of true Liesegang system. The IOC, however, is the product of the geochemical drive for organization combined with microbial activity.

This region hosts a set of relatively fresh craters and surrounding ejecta field, an unusual dark hill named Arisia Tholus, and a orange (false color) diffuse material surrounding the crater Octavia. Stratigraphically, from oldest to youngest, three increasingly larger impact craters named Minucia, Calpurnia, and Marcia make up a snowman-like feature, which is surrounded by a zone of dark material interpreted to consist of impact ejecta and possibly impact melts. The floor of Marcia contains a pitted terrain thought to be related to release of volatiles (1). The dark ejecta field has an enhanced signature of H, possibly derived from carbonaceous chondritic material that accumulated in Vesta's crust (2,3). The dark ejecta has a spectrally distinctive behavior with shallow pyroxenes band depths. Outside the ejecta field this quadrangle contains various cratered terrains, with increasing crater abundance moving south to north away from the Rheasilvia Basin. Arisia Tholus, originally suggested as an ancient volcano, appears to be an impact-sculpted basin rim fragment with a superposed dark-rayed impact crater. There remains no unequivocal evidence of volcanic features on Vesta's surface, likely because basaltic material of the HED meteorite suite demonstrates magmatism ended very early on Vesta (4). Ongoing work includes application of crater statistical techniques to obtain model ages of surface units, and more detailed estimates of the compositional variations among the surface units.

It was used to map Quasi-Circular Depressions (QCDs) on Mars which represent a very large but buried population of impact craters, and to help identify Circular Thin Areas (CTAs) in model crustal thickness data which indicate the presence of several previously unknown very large impact basins on Mars. More recently GRIDVIEW was used to map QCDs and CTAs for the Moon, which, in combination with the more recent LOLA and LOLA-derived data, indicates a population of impact basins significantly larger than previously thought. Detailed study of these QCDs and CTAs for basins > 300 km in diameter revealed that, for well-known basins, the ring of thickened crust in the CTA signature sometimes was situated well inside the most prominent topographic ring normally taken as the basin diameter. This appears to be especially true of some multi-ring basins but not the case for larger craters 200-300 km in diameter, just below the size cutoff for lunar basins. In order to better understand the relationship between the subsurface crustal structure represented by the model CTA signatures and the surface topographic structure, we began a systematic comparison of the QCD and CTA signatures for basins as a function of diameter, location on the Moon, and multi-ring status. We also noted whether or not mare fill was related to the location of the CTA peak ring compared to the topographic peak ring. These comparisons were done both using the fit-a-ring feature in GRIDVIEW and its profiling tool. We find for basins 1.3. For much larger basins the CTA/QCD diameter approaches 1 again as for the small features. Additional variations appear in our limited preliminary study to depend on the multi-ring nature of basins, but further work is required to understand these trends.

It is often used to study gridded topography products from instruments such as the Mars Orbiter Laser Altimeter (MOLA) or the Lunar Orbiter laser Altimeter (LOLA), but also can work well with other gridded data such as magnetic anomaly or gamma ray spectrometry. The application focuses on the visual display of data and includes tools for color adjustments as well as shaded relief that allow users to highlight and enhance areas of interest. The program has many additional features, including measurement and plotting tools that have been successfully used for the mapping of craters and buried basins, as well as the measurement of distance, height, slope, area, and volume of various geomorphological features. For measurement accuracy, diameter constants for the Earth, Mars, and the Moon can be selected or the user can enter an arbitrary value to enable accurate measurement of data from nearly any sized circular body. Other program features include: latitude/longitude/data value tracking, global rotation and zooming, color stretching and contouring, profile plotting, image output, overlay of other data contours, image overlay, advanced area and volume calculation, and an interactive data fly through. Users can load gridded data of various formats into GRIDVIEW, including the Experiment Gridded Data Records (EGDR) ".img" format that NASA's Planetary Data System (PDS) uses to distribute MOLA topographic data, the IDL specific ".sav" format, and the Generic Mapping Tools NetCDF ".grd" format.

It is free, easy to use, and is also available for teachers and students to conduct research in the classroom, or by the general public who may be interested in such innovative technology. IDL, short for Interactive Data Language, is a programming language used for data analysis. It is popular in particular areas of science, such as in astronomy imaging. The instrument data is collected in a way very similar to a spreadsheet, with values occurring in a tabular manner. These tabular data are then converted into images based on the values assigned to intensities. For example, we use GRIDVIEW for manipulating images of the topography of the Moon and Mars. The topographical data for Moon that GRIDVIEW works is topographical data collected in values determined by the timing between the pulse and return bounce of laser beams sent to the lunar surface from the Lunar Reconnaissance Orbiter instrument called LOLA (Lunar Reconnaissance Orbiter Altimeter) and returned to the spacecraft. So, simply stated, the IDL program takes data values and, in conjunction with GRIDVIEW, converts the data into a visual image based on the data. Once an image is created with the IDL software, GRIDVIEW allows you to manipulate parameters to zoom in, zoom out, crop, and change layers in the images created. There are many other options for manipulating the images in GRIDVIEW to enhance research initiatives in geomorphology of the Moon and Mars. The free IDL data in association with GRIDVIEW is currently available for Moon and Mars only.

Our focus has been to employ the stretching, contouring, profiling, circle-fitting and other capabilities of GRIDVIEW to search for Quasi-Circular Depressions (CTAs) in MOLA, LOLA and other topographic data, and for Circular Thin Areas (CTAs) in Mars and Moon model crustal thickness data. Both QCDs and CTAs likely represent buried or obscured impact craters not readily visible in image data. We found clear evidence for a much larger population of buried impact craters in the northern lowlands of Mars (Frey et al. 2002), suggesting that part of the Red Planet is not significantly younger than the southern highlands. Edgar and Frey (2008) found that the N(300) crater retention ages of both areas were essentially identical, a conclusion confirmed by Wyatt (unpublished data) using more recent crustal thickness data for Mars. MOLA topographic data and MOLA-derived crustal thickness data were used to both identify a large number of previously unrecognized very large impact basins (D> 1000 km) on Mars and to determine relative crater retention ages for them (Frey, 2008). The distribution of N(300) CRAs suggested most formed in a relatively short interval of time. This dating also suggested the main magnetic field of Mars disappeared during this period (Lillis et al., 2008), because only the youngest basins systematically lack a remagnetized signature. Similar QCD and CTA analysis of first Clementine (Frey, 2011) and more recently LOLA topographic and LOLA-derived crustal thickness data for the Moon (Frey et al., 2011) revealed a significantly larger population of impact basins > 300 km in diameter than previously known. N(50) CRAs suggest a two-peak distribution of ages (Frey, 2012). An improved counting process confirms the two peaks, perhaps indicating both a pre-Nectaris Early Heavy Bombardment (EHB) as well as a Late Heavy Bombardment (LHB) on the Moon (Frey and Burgess, 2012, this meeting), with obvious implications for the early bombardment history of the Earth.

This paper will discuss the evidence for and predictions of sea level rise followed by the needs of stakeholders such as regional planners and civil engineers. Sallenger, Doran and Howd (2012) and Ezer and Corlett (personal communication) have shown strong evidence for the acceleration of sea level rise in the 0.05-0.1 mm y (super -2) range rather than a simple linear increase. They attribute this to changes in the dynamic sea level rise component such as wind field and North Atlantic Ocean dynamic features such as the Gulf Stream (Ezer, 2001). Sweet, Zervas and Gill (2009) attributed the anomalously high sea level along the mid-Atlantic in 2009 to dynamic SLR. These accelerations suggest that the higher estimates of SLR in IPCC reports may be better estimates. Even if the strength and frequency of storms remains steady, rising sea level will result in increased damage. We will give several examples of how stakeholders are dealing with increased flooding risk due to sea level rise: cities, NASA facilities, and shipyards. Regional planners and engineers require estimates of local sea level out 50 to 100 years as that is the lifetime of coastal infrastructure: docks, piers, levees, etc.. They also require error bars on these estimates. Studies of dynamic SLR are required to provide this information. Emergency managers also need short term predictions of flooding risk. In 2009 sea level along the Northeast U.S. coastline remained around 0.3 m above predicted for months. Rising sea level will acerbate the effects of these short term fluctuations. Predicting such shorter term variations in sea level just as we observe and predict the ENSO cycle may become necessary for disaster preparation. Finally we will discuss how flood insurance rates are subsidized and do not reflect the true risk of coastal flooding and do not incorporate the likelihood of future sea-level rise.

The spectral characteristics of a approximately 200 m wide and 6.5 km long ridge at the northern end of a large channel system emanating from Mount Sharp were examined using this data. The ridge is composed of finely layered strata dipping to the north and exhibits a strong spectral signature of crystalline hematite. To the west, the ridge transitions to an escarpment overlain by younger strata and occasionally exposed through erosional windows; to the east, debris flows from Mount Sharp cover and obscure the ridge. The ridge is stratigraphically directly above the clay bearing strata. We interpret the ridge to be formed by erosion associated with outflow from the channel that preferentially stripped away flanking strata that were not as well cemented by hematite. We hypothesize that the hematite accumulated where anoxic groundwater discharged and came into contact with an oxidizing Martian atmosphere. Anoxic water may have originated as precipitation that percolated through the mound, leaching Fe (super 2+) from the overlying sulfate layers until encountering the clay acquiclude. Alternatively, anoxic Fe (super 2+) -rich waters at Gale could have originated by groundwater discharge near the base of the mound. In this scenario, dissolved Fe (super 2+) could be leached from an underlying basaltic aquifer or possibly the clay layer. Given that iron oxidation reactions on Earth may be mediated by chemolithotrophic microorganisms, the ridge provides a compelling site for a detailed measurement campaign by the Mars Science Laboratory Curiosity rover.

Along the eastern interior wall of the crater are a number of channels that terminate at an elevation approximately 500 meters above the modern crater floor. This observation could suggest the presence of a former base level at the surface of lake that once filled the crater. Also along the east interior of the crater is a broad terrace that might have formed from deposition of fluvial sediment into standing water. Within the floor of the crater are layered sediments that contain spectroscopic features similar to Mg-rich carbonates and Fe-Mg-rich clay minerals. In addition, impact ejecta from a younger, nearby crater (Keren Crater) deposited into Mclaughlin appears to have flow-like morphologies that are consistent with deposition in a wet environment. In fact, a number of possible debris flow units are present on the floor of McLaughlin. Finally, Keren's ejecta are not altered where they are found outside of McLaughlin (based on thermal infrared spectroscopy), but are altered within the basin, below the proposed base level. Taken together, these observations point to the former presence of a lacustrine environment within McLaughlin Crater, which may have experienced episodes of rapid deposition that would be advantageous for the preservation of organic matter if any was present at the time. The source of the water within the crater could have been groundwater from the deep crust. McLaughlin Crater is among the most likely places to find evidence for groundwater-fed springs because the crater is deep and it occurs adjacent to the global topographic dichotomy boundary. The neutral-to-alkaline, Mg-Fe-rich fluids implicated by the mineralogy of putative lacustrine sediments are consistent with predicted fluid chemistry from groundwater that evolved in a basaltic crust. This site could provide access for exploration of a possible ancient, deep martian biosphere.

This research uses gridded GRACE Tellus satellite data to quantify changes in total land water storage, including those of groundwater. Global Land Data Assimilation System land components such as soil moisture, canopy moisture, and snow, are subtracted from the GRACE data to isolate the groundwater component. The resulting trends show that most continents are gaining in groundwater storage, which is consistent with GRACE-based estimates of zero-to-increasing changes in total land water. Results indicate a negative contribution to current rates of GMSLR for the GRACE time period, which is in contrast to the long term, positive contribution identified in recent studies.

The existence and extent of such ring systems depend on the thickness of the mechanical lithosphere at the time and place of impact. Icy satellites offer a valuable laboratory to explore this paradigm, and Ron Greeley took particular interest in these as part of his work on the Galileo imaging team, which we extend here. The two largest impact structures on Europa are Tyre ( nearly equal 160 km across) and Callanish ( nearly equal 95 km across). Tyre and Callanish both possess compact systems of circumferential graben-like troughs, essentially miniature versions of the much larger Valhalla and Asgard/Utgard multiringed structures on Callisto, and plausibly related to the hemispherical-scale furrow systems on Ganymede. The compact nature of these structures implies a relatively thin icy lithosphere, consistent with present-day steep temperature gradients due to strong tidal heating. We use measurements of trough width (and depth) to constrain heat flows at the time of impact. Assuming the troughs are graben, and that they originated or nucleated at the brittle-ductile transition (BDT), we find that fault intersection depths are equal to graben width (to within 10%). The depth to the BDT is related to the surface heat flux through the temperature profile in the ice shell and the rheology of water ice. The BDT occurs at a depth and temperature where the differential stress required for ductile flow at a given strain rate is equal to brittle yield stress. For the high strain rates appropriate to post-impact crater collapse, we find anomalously high heat flows, >300 mW m (super -2) . If, however, the "hourglass" model of graben formation is more correct than the classic "keystone" model (R.A. Schultz et al., in The Geology of Mars, 2007), then our BDT depths are underestimates. Furthermore, preexisting fractures imply lower thermal conductivity for lithospheric ice, and the combination implies true heat flows closer to 100 mW m (super -2) , similar to other literature estimates. Conductivity remains a principal uncertainty, but one amenable to future observational constraints, especially through an active remote sensing technique such as ice-penetrating radar.

Although largely unrecognized in the planetary community, terrestrial inflated sheet flows also display morphologies that share many commonalities with lava plains on Mars. The McCartys lava flow field is among the youngest ( approximately 3000 yrs) basaltic flows in the continental United States. The southwest sections of the flow displays smooth, flat-topped plateaus with irregularly shaped pits and hummocky inter-plateau units that form a polygonal surface. Plateaus are typically elongate in map view, up to 20 m high and display lineations within the glassy crust. Lineated surfaces occasionally display small < 1 m diameter lava coils. Lineations are generally straight and parallel each other, sometimes for over 100 meters. The boundaries between plateaus and depressions are also lineated and tilted to angles sometimes approaching vertical. Plateau-parallel cracks, sometimes containing squeeze-ups, mark the boundary between tilted crust and plateau. Some plateau depressions display level floors with hummocky surfaces, while some are bowl shaped with floors covered in broken lava slabs. The lower walls of pits sometimes display lateral, sagged lava wedges. Infrequently, pit floors display the upper portion of a tumulus from an older flow. In some places the surface crust has been disrupted forming a slabby texture. Slabs are typically on the scale of a meter or less across and no less than 7-10 cm thick. The slabs preserve the lineated textures of the undisturbed plateau crust. It appears that this style of terrain represents the emplacement of an extensive sheet that experiences inflation episodes within preferred regions where lateral spreading of the sheet is inhibited, thereby forming plateaus. Rough surfaces represent inflation-related disruption of pahoehoe lava and not a'a lava. Depressions are often the result of non-inflation and can be clearly identified by lateral squeeze-outs along the pit walls that form when the rising crust exposes the still liquid core of the sheet. The plains of Tharsis and Elysium, Mars, display many analogous features.

An example is the wing leading-edge impact-detection system that monitors the debris hazards to the Space Shuttle Orbiter's reinforced carbon-carbon panels. Since return to flight after the Columbia accident, the system was developed and subsequently deployed on board the orbiter to detect ascent and on-orbit debris impacts, so as to support the assessment of wing leading edge structural integrity before orbiter reentry. As structural health monitoring is inherently an inverse problem, the analyses involved, including those performed for this system, tend to be associated with significant uncertainty. The use of probabilistic approaches to handle the uncertainty has resulted in the successful implementation of many development and application milestones.

The geomorphology of these features suggests that they formed by collapse, opposed to meteor impact. At least one depression ( approximately 55 by 85 km) displays geologic features indicating a complex, multi-stage collapse history. Features within and around the collapse structure indicate volcanic processes. The complex occurs within Hesperian ridged plains of likely volcanic origin and displays no crater rim or evidence for ejecta. Instead the depression consists of a series of circumferential graben and down-dropped blocks which also display upper surfaces similar to ridged plain lavas. Large blocks within the depression are tilted towards the crater center, and display graben that appear to have originally been linked with circumferential graben outside of the complex related to earlier collapse events. A nearly 700 m high mound exists along a graben within the complex that might be a vent. The deepest depression displays two sets of nearly continuous terraces, which we interpret as high-stands of a drained lava lake. These features appear similar to the "black ledge" described during the Mauna Iki eruption in 1959. A lacustrine origin for the terraces seems unlikely because of the paucity of channels found in or around the depression that could be linked to aqueous surface processes. In addition, there is no obvious evidence for lacustrine sediments within the basin. Together with the presence of significant faulting that is indicative of collapse we conclude that this crater complex represents a large caldera formed in the Late Noachian to Early Hesperian. Other linear and irregular depressions in the region also might be linked to ancient volcanism. If that hypothesis is correct, it suggests that northern Arabia Terra could contain a large, previously unrecognized highland igneous province. Evacuation of magma via explosive and effusive activity produced localized collapse, might have contributed to nearby ridged plains, and pyroclastic materials erupted from these vents might have supplied sediments in fretted terrain and other deposits. The recognition of volcanoes within Arabia Terra expands the known extent of Noachian-Hesperian volcanism to cover much of the preserved martian highland crust.

Neutrons emitted by the pulsed neutron generator (PNG) interact with the nuclei in the soil, causing the nuclei to emit gamma rays whose energies are specific to the nuclei that emitted them. These gamma rays are detected and their rate and energy are measured by a gamma-ray spectrometer. Numerical gamma-ray data returned by PING are summed and made into a graphical representation of the spectrum as energy vs. gamma-ray count using Igor Pro 6. The data are then run through custom software procedures that allow for easy calibration and spectral analysis. Each energy peak in the gamma-ray spectra represents the presence of a unique isotope while the area underneath each peak represents the gamma-ray count rate, which can be converted to a weight percent of that isotope in the material. Various configurations using Columbia River Basalt, Concord Gray Granite, and polyethylene plates are used as planetary analogs in experiments designed to test PING. The gamma-ray spectra corresponding to these experiments are analyzed by finding the locations of the energy peaks and determining their area by using peak-fitting methods in Igor Pro 6. In this analysis, advanced error reduction methods are applied in order to retrieve the most accurate data possible from each peak in the spectra. Future work includes comparison to chemical assays of the analogs, which will be performed by other members of the group.

It substantially affects the regolith's strength, the angle of repose, the packing density, and the ability of regolith particles to attach to and abrade spacecraft materials or clog air filters. For these reasons, simulants are needed to reproduce regolith particle shapes for testing spacecraft that interacts with the lunar surface. Difficulties in assessing "how good" a simulant reproduces the shape of lunar particles stem from the lack of shape measurements obtained on lunar particles, compounded by the lack of a strict definition of shape or a way to quantifiably measure shape. This paper presents a general method for measuring and comparing particle shapes, and provides shape measurements for six lunar-regolith simulants. The method of evaluating particle shape presented here involves Fine Particle Analysis and corresponding image analysis to extract the maximum Feret diameter, Feret diameter of the minor axis of the inertial ellipse, mean diameter, sieve diameter, area, and perimeter length from images with an approximately 4.4 mu m pixel resolution. From those, aspect ratio and Heywood factor are computed. Data processing involves calculating the frequency distributions of particle shapes according to their sieve diameter, aspect ratio, and Heywood factor. The resulting graphical representations indicate that the majority of the lunar regolith simulant particles, in two-dimensional projection, can be well represented by a mixture of ellipses and rectangles of varying aspect ratios. The differences between simulant particle shapes, and lunar regolith particle shapes measured in the future, can be quantified by differencing the accumulated distributions. Thus, this paper presents a new method of particle shape analysis and a new way to quantifiably compare particle shapes.

The stresses and conditions in future exploration missions, however, will include limited ability to return to Earth and limited-if any-resupply, time lags of 40 min in two-way communications with Earth, and other unknown dangers; and home Earth will be a speck in the sky. Planning for these missions will require complex decision-making regarding many aspects of crew behavior and performance including the appropriate/optimal amount of autonomy crewmembers will require to develop effective schedules and strategies for work and recreation and to deal successfully with unanticipated situations.

Astronauts and other exposed groups are classified as never-smokers (NS), defined as lifetime use of less than 100 cigarettes. In the past, radiation risk estimates have been made using average U.S. population rates for cancer and all causes of death, which may lead to overestimation of radiation risks for NS. In this report, age- and gender-specific radiation carcinogenesis risk calculations for NS and the average U.S. population are compared. Lung is the major tissue site for smoking and radiation-related cancer. However, other radiogenic cancers where tobacco has been shown to increase population cancer rates are esophagus, oral cavity, salivary gland, bladder, stomach, liver, colorectal, and leukemia. After adjusting U.S. cancer rates to remove smoking effects, radiation risks for lung and other cancers were estimated using the multiplicative risk model and a mixture model, with weighted contributions for additive and multiplicative risk transfer. Radiation mortality risks for NS were reduced compared to the average U.S. population by more than 20% and 50% in the mixture model and multiplicative transfer models, respectively. The authors discuss possible mechanisms of cancer risks from radiation and tobacco that suggest multiplicative effects could occur. These results suggest that improved understanding of possible synergisms between cancer initiators and promoters, such as radiation and tobacco, would greatly improve risk estimates and reduce uncertainties for differentially exposed groups, including NS.

As space radiations traverse spacecraft, habitat shielding, or tissues, their energies and compositions are altered by interactions with the shielding. Modifications to the radiation fields arise from atomic interactions of charged particles with orbital electrons and nuclear interactions leading to projectile and target fragmentation, including secondary particles such as neutrons, protons, mesons, and nuclear recoils. The transport of space radiation through shielding can be simulated using Monte Carlo techniques or deterministic solutions of the Boltzmann equation. To determine shielding requirements and to resolve radiation constraints for future human missions, the shielding evaluation of a spacecraft concept is required as an early step in the design process. To do this requires (1) accurate knowledge of space environmental models to define the boundary condition for transport calculations, (2) transport codes with detailed shielding and body geometry models to determine particle transmission into areas of internal shielding and at each critical body organ, and (3) the assessment of organ dosimetric quantities and biological risks by applying the corresponding response models for space radiation against the particle spectra that have been accurately determined from the transport code. This paper reviews current transport codes and analyzes their accuracy through comparison to laboratory and spaceflight data. This paper also introduces a probabilistic risk assessment approach for the evaluation of radiation shielding.

Here we asked whether non-myeloablative transplantation of MOG expressing BM (pMOG-bone marrow transplantation (BMT)) can also provide the same protection. Using stepwise reduction of irradiation doses, 275cGy irradiation with pMOG-BMT protected 100% of mice from EAE development even with two subsequent re-challenge with MOG. Irradiation doses <275cGy produced dose-dependent partial protection with significant disease protection still evident at 50cGy. Splenocytes from 275cGy recipients proliferated to MOG stimulation in vitro, indicating that MOG-reactive cells are present in the periphery but failed to induce disease. MOG-stimulated splenocytes produced little or no interleukin-17, interferon-γ, granulocyte-monocyte colony stimulating factor and tumor necrosis factor-α compared with EAE control. Adoptive transfer of CD4 T cells from EAE-resistant mice into Rag2(-/-) mice devoid of MOG expression resulted in MOG-induced EAE in 74% of mice. Treatment of EAE-resistant mice with anti-programmed death 1 (PD-1) monoclonal antibody-induced EAE in 67% of mice. We conclude that non-myeloablative transplantation of self-antigen expressing BM induces robust peripheral tolerance that completely prevented EAE development. Our findings implicate clonal anergy and the PD-1 pathway in the maintenance of peripheral tolerance.

Net primary production (NPP) flux for atmospheric carbon dioxide has varied slightly from year-to-year, but was predicted to have increased over short multi-year periods in the regions of the high-latitude Northern Hemisphere, South Asia, Central Africa, and the western Amazon since the year 2000. These CASA results for global NPP were found to be in contrast to other recently published modeling trends for terrestrial NPP with high sensitivity to regional drying patterns. Nonetheless, periodic declines in regional NPP were predicted by CASA for the southern and western Untied States, the southern Amazon, and southern and eastern Africa. NPP in tropical forest zones was examined in greater detail to discover lower annual production values than previously reported in many global models across the tropical rainforest zones, likely due to the enhanced detection of lower production ecosystems replacing primary rainforest.

Data from three different satellite sensors - including the Oceansat-2 scatterometer, the Moderate-resolution Imaging Spectroradiometer, and the Special Sensor Microwave Imager/Sounder - are combined to obtain composite melt maps, representing the most complete melt conditions detectable across the ice sheet. Satellite observations reveal that melt occurred at or near the surface of the Greenland ice sheet across 98.6% of its entire extent on 12 July 2012, including the usually cold polar areas at high altitudes like Summit in the dry snow facies of the ice sheet. This melt event coincided with an anomalous ridge of warm air that became stagnant over Greenland. As seen in melt occurrences from multiple ice core records at Summit reported in the published literature, such a melt event is rare with the last significant one occurring in 1889 and the next previous one around seven centuries earlier in the Medieval Warm Period.

This information is required in different applications such as urban air quality analysis, aerosol source identification etc. The quality of high resolution aerosol data is directly linked to the quality of cloud mask, in particular detection of small (sub-pixel) and low clouds. This work continues research in this direction, describing a technique to detect small clouds and introducing the "smoke test" to discriminate the biomass burning smoke from the clouds. The smoke test relies on a relative increase of aerosol absorption at MODIS wavelength 0.412 mu m as compared to 0.47-0.67 mu m due to multiple scattering and enhanced absorption by organic carbon released during combustion. This general principle has been successfully used in the OMI detection of absorbing aerosols based on UV measurements. This paper provides the algorithm detail and illustrates its performance on two examples of wildfires in US Pacific North-West and in Georgia/Florida of 2007.

Pitted terrain is characterized by irregular rimless depressions found in and around several impact craters, with a distinct morphology not observed on other airless bodies. Similar terrain is associated with numerous martian craters, where pits are thought to form through degassing of volatile-bearing material heated by the impact. Pitted terrain on Vesta may have formed in a similar manner, which indicates that portions of the surface contain a relatively large volatile component. Exogenic materials, such as water-rich carbonaceous chondrites, may be the source of volatiles, suggesting that impactor materials are preserved locally in relatively high abundance on Vesta and that impactor composition has played an important role in shaping the asteroid's geology.

Global Fe/O and Fe/Si ratios are consistent with HED compositions. Neutron measurements confirm that a thick, diogenitic lower crust is exposed in the Rheasilvia basin, which is consistent with global magmatic differentiation. Vesta's regolith contains substantial amounts of hydrogen. The highest hydrogen concentrations coincide with older, low-albedo regions near the equator, where water ice is unstable. The young, Rheasilvia basin contains the lowest concentrations. These observations are consistent with gradual accumulation of hydrogen by infall of carbonaceous chondrites-observed as clasts in some howardites-and subsequent removal or burial of this material by large impacts.

Even with the currently small sample, there is a wide dispersion in abundance ratios and little if any systematic difference between Jupiter-family comets (JFCs) and long-period and Halley-type comets (LPCs and HTCs). We argue that the cometary observations require reactions on grain surfaces to convert CO to CO (sub 2) and also require formation of all types of comets in largely, but not entirely, overlapping regions, probably between the CO and CO (sub 2) snow lines. Any difference in the regions of formation is in the opposite direction from the classical picture with the JFCs having formed closer to the Sun than the LPCs. In the classical picture, the LPCs formed in the region of the giant planets and the JFCs formed in the Kuiper Belt. However, these data suggest, consistent with suggestions on dynamical grounds, that the JFCs and LPCs formed in largely overlapping regions where the giant planets are today and with JFCs on average forming slightly closer to the Sun than did the LPCs. Presumably at least the JFCs passed through the scattered disk on their way to their present dynamical family. Copyright (Copyright) 2012. The American Astronomical Society. All rights reserved.

The impacts are examined in terms of diagnostic top-of-the atmosphere shortwave (SW) and longwave (LW) cloud radiative effect (CRE) calculations for a range of assumptions and overlap parameter specifications. The investigation is conducted for two distinct cloud schemes, one that comes with the standard GEOS-5 distribution, and another used experimentally for its enhanced cloud microphysical capabilities. Both schemes are coupled to a cloud generator allowing arbitrary cloud overlap specification. Results show that cloud overlap radiative impacts are significantly stronger in the operational cloud scheme where a change of cloud fraction overlap from maximum-random to generalized results in global changes of SW and LW CRE of similar to 4 Wm super(-2), and zonal changes of up to similar to 10 Wm super(-2). This is an outcome of fewer occurrences (compared to the other scheme) of large layer cloud fractions and fewer multi-layer situations where large numbers of atmospheric layers are simultaneously cloudy, both conditions that make overlap details more important. The impact of the specifics of condensate distribution overlap on CRE is much weaker. Once generalized overlap is adopted, both cloud schemes are only modestly sensitive to the exact values of the overlap parameters. When one of the CRE components is overestimated and the other underestimated, both cannot be driven simoultaneously towards observed values by adjustments to cloud condensate heterogeneity and overlap specifications alone.

Here we describe the development of the habitable zone concept, its application to our own solar system, and its subsequent application to exoplanetary systems. We further apply this to planets in extreme eccentric orbits and show how they may still retain life-bearing properties depending upon the percentage of the total orbit which is spent within the habitable zone.

Our 2-year time-series data included physical parameters, nutrient concentrations, and chlorophyll a concentrations. A detailed phytoplankton assemblage structure was examined in the second year. During the 2-year study, chlorophyll a concentration (and ocean color satellite imagery) indicated that phytoplankton blooms occurred in January/February during mixing conditions and in early autumn under stratified conditions. The chlorophyll a concentrations ranged from 0.25 mu g l-1 to 15.49 mu g l-1 during the 2-year period. We were able to discriminate approximately 116 different species under phase contrast microscopy. Dominant phytoplankton included Skeletonema costatum, Rhizosolenia spp., and Pseudo-nitzschia pungens. In an attempt to determine phytoplankton species competition/succession within the assemblage, we calculated a Shannon Weaver diversity index for our diatom microscopy data. Diatom diversity was greatest during the winter and minimal during the spring. Diatom diversity was also greater at nearshore stations than at offshore stations. Individual genera appeared patchy, with surface and subsurface patches appearing abruptly and persisting for only 1-2 months at a time. The distribution of individual species differed significantly from bulk variables of the assemblage (chlorophyll a) and total phytoplankton assemblage (cells), which indicates that phytoplankton species may be limited in growth in ways that differ from those of the total assemblage. Our study demonstrated a highly diverse phytoplankton assemblage throughout the year, with opportunistic species dominating during spring and fall in response to seasonal changes in temperature and nutrients in the southern MAB.

We construct a redshift-finding algorithm using combinations of the signal to noise of all the lines falling in the Z-Spec bandpass to determine redshifts with high confidence, even in cases where the signal to noise in individual lines is low. We measure the dust continuum in all sources and secure CO redshifts for four out of five (z ~ 1.5-3). In one source, SDP. 17, we tentatively identify two independent redshifts and a water line, confirmed at z = 2.308. Our sources have properties characteristic of dusty starburst galaxies, with magnification-corrected star formation rates of 10 super(2-3) M sub([middot in circle]) yr super(-1). Lower limits for the dust masses (~ a few 10 super(8) M sub([middot in circle])) and spatial extents (~1 kpc equivalent radius) are derived from the continuum spectral energy distributions, corresponding to dust temperatures between 54 and 69 K. In the local thermodynamic equilibrium (LTE) approximation, we derive relatively low CO excitation temperatures ([lap] 100 K) and optical depths ([tau] [lap] 1). Performing a non-LTE excitation analysis using RADEX, we find that the CO lines measured by Z-Spec (from J = 4 [arrowright] 3 to 10 [arrowright] 9, depending on the galaxy) localize the best solutions to either a high-temperature/low-density region or a low/temperature/high-density region near the LTE solution, with the optical depth varying accordingly. Observations of additional CO lines, CO(1-0) in particular, are needed to constrain the non-LTE models.

VLBI provides an important linkage to astronomy through, for instance, the determination of very precise coordinates of extragalactic radio sources. Additionally, it contributes to determining parameters of relativistic and cosmological models. After a short review of the history of geodetic VLBI and a summary of recent results, this paper describes future perspectives of this fascinating technique. The International VLBI Service for Geodesy and Astrometry (IVS), as a service of the International Association of Geodesy (IAG) and the International Astronomical Union (IAU), is well on its way to fully defining a next generation VLBI system, called VLBI2010. The goals of the new system are to achieve on scales up to the size of the Earth an accuracy of 1 mm in position and of 0.1 mm/year in velocity. Continuous observations shall be carried out 24 h per day 7 days per week in the future with initial results to be delivered within 24 h after taking the data. Special sessions, e.g. for monitoring the Earth rotation parameters, will provide the results in near real-time. These goals require a completely new technical and conceptual design of VLBI measurements. Based on extensive simulation studies, strategies have been developed by the IVS to significantly improve its product accuracy through the use of a network of small ( approximately 12 m) fast-slewing antennas. A new method for generating high precision delay measurements as well as improved methods for handling biases related to radio source structure, system electronics, and deformations of the antenna structures has been developed. Furthermore, as of January 2012, the construction of ten new VLBI2010 sites has been funded, with good prospects for one dozen more antennas, which will improve the geographical distribution of geodetic VLBI sites on Earth and provide an important step toward a global VLBI2010 network. Within this paper, the Global Geodetic Observing System (GGOS) of the IAG will also be introduced and the contribution of VLBI to GGOS will be described. Abstract Copyright (2012) Elsevier, B.V.

Previous USA, former Soviet Union, and European missions have identified a wide diversity of Martian environments and a complex series of physical and chemical processes that operate or have operated on the Martian surface. Rover exploration, and associated chemical and isotopic analysis of geological material, allows us to understand and resolve the environmental evolution of the area around the landing site, and the proposed scientific target of the geological exploration part of this Martian mission will have a sedimentary or volcanic focus. Investigating sedimentary rocks will mean that this mission follows the road map advocated by NASA and European Space Agency (ESA) for the search for life on Mars. However, focusing this mission on volcanic rocks may open up a new field of research in Mars science. Although the focus has not been finalized, this future mission to Mars needs to be evaluated and supported by a broad community of Japanese Earth and planetary scientists.

The reflectance of CV chondrite spectra is variable, ranging from approximately 5% to 13% at 0.56 mu m, and approximately 5% to 15% at the 0.7 mu m region local reflectance maximum. Overall slopes range from slightly blue to red for powders, while slab spectra are strongly blue-sloped. With increasing average grain size and/or removal of the finest fraction, CV spectra generally become more blue-sloped. CV spectra are characterized by ubiquitous absorption features in the 1 and 2 mu m regions. The 1 mu m region is usually characterized by a band centered near 1.05-1.08 mu m and a band or shoulder near 1.3 mu m that are characteristic of Fe-rich olivine. Band depths in the 1 mu m region for powdered CVs and slabs range from approximately 1% to 10%. The 2 mu m region is characterized by a region of broad absorption that extends beyond 2 mu m and usually includes band minima near 1.95 and 2.1 mu m; these features are characteristic of Fe (super 2+) -bearing spinel. The sample suite is not comprehensive enough to firmly establish whether spectral differences exist between CVR, CV (sub OxA) , and CV (sub OxB) subclasses, or as a function of metamorphic grade. However, we believe that the mineralogic and petrologic differences that exist between these classes, and with varying petrologic subtype (CV3.0-->3.7), may not be significant enough to result in measurable spectral differences that exceed spectral variations within a subgroup, within an individual meteorite, or as a function of grain size. Terrestrial weathering seems to affect CV spectra most noticeably in the visible region, resulting in more red-sloped spectra for finds as compared to falls. The search for CV parent bodies should focus on the detection of olivine and spinel absorption bands, specifically absorption features near 1.05, 1.3, 1.95, and 2.1 mu m, as these are the most commonly seen spectral features of CV chondrites.

Our model predicts the explosive degassing of water from this pitted material, which is assumed to originally be water-bearing, impact melt-rich breccia at the time of deposition. This process is analogous to what occurred in the fall-out suevite deposits at the Ries impact structure in Germany. At Ries, impact heating of water-bearing target material resulted in the rapid degassing of its water and other volatiles. The martian environment plays an important role in enhancing the effects of this degassing by increasing the flow-speed of the escaping gas. The high flow-rate of gas through particulate materials, such as suevite, tends to quickly form segregation channels or vent pipes, similar to those found in the Ries deposits. These pipes act as conduits for the efficient high-speed escape of the gas and small clasts that it entrains. Escaping gas and entrained clasts abraded and eroded the conduit walls, flaring them to form pits above a network of pipes.

The deterministic propagation of model parameter uncertainty is achieved through the introduction of additional stochastic coordinates. Particular attention is given to the construction of specialized piecewise polynomial approximation spaces well suited to the high-order accurate approximation of solution discontinuities in both physical and stochastic dimensions without exhibiting Gibbs-like oscillations characteristic of polynomial approximation. The proposed discretization easily retrofits existing finite-volume CFD codes in use today. Numerical results are presented for inviscid Burgers equation with uncertain initial data as well as the compressible Reynolds-averaged Navier-Stokes equations with uncertain boundary data and turbulence model parameters.

Virtual guidance is a form of just-in-time training developed to allow novice ultrasound operators to acquire diagnostically-adequate images of clinically relevant anatomical structures using a prerecorded audio/visual tutorial viewed in real-time. Methods: Individuals without previous experience in ultrasound were recruited to perform carotid artery (N=10) and ophthalmic (N=9) ultrasound examinations using virtual guidance as their only training tool. In the carotid group, each untrained operator acquired two-dimensional, pulsed and color Doppler of the carotid artery. In the ophthalmic group, operators acquired representative images of the anterior chamber of the eye, retina, optic nerve, and nerve sheath. Ultrasound image quality was evaluated by independent imaging experts. Results: Of the studies, 8 of the 10 carotid and 1 7 of 18 of the ophthalmic images (2 images collected per study) were judged to be diagnos-tically adequate. The quality of all but one of the ophthalmic images ranged from adequate to excellent. Discussion: Diagnostically-adequate carotid and ophthalmic ultrasound examinations can be obtained by previously untrained operators with assistance from only an audio/video tutorial viewed in real time while scanning.

This control is examined here using a simple water balance model and multidecadal observations covering the conterminous United States. Under the assumption that the relevant soil moisture-evapotranspiration and soil moisture-runoff relationships are, to first order, universal, the simple model illustrates the degree to which they interact to determine spatial distributions of hydroclimatic means and variability. In the process, the simple model provides estimates for the underlying relationships that operate in nature. The hydroclimatic sensitivities established with the simple water balance model can be used to evaluate more complex land surface models and to guide their further development, as demonstrated herein with an example.

While research has evaluated the spatiotemporal distribution of extreme rainfall and landslides at local or regional scales using in situ data, few studies have mapped rainfall-triggered landslide distribution globally because of the dearth of landslide data and consistent precipitation information. This study uses a newly developed global landslide catalog (GLC) and a 13-yr satellite-based precipitation record from Tropical Rainfall Measuring Mission (TRMM) data. For the first time, these two unique products provide the foundation to quantitatively evaluate the co-occurrence of precipitation and rainfall-triggered landslides globally. Evaluation of the GLC indicates that 2010 had a large number of high-impact landslide events relative to previous years. This study considers how variations in extreme and prolonged satellite-based rainfall are related to the distribution of landslides over the same time scales for three active landslide areas: Central America, the Himalayan arc, and central eastern China. Several test statistics confirm that TRMM rainfall generally scales with the observed increase in landslide reports and fatal events for 2010 and previous years over each region. These findings suggest that the co-occurrence of satellite precipitation and landslide reports may serve as a valuable indicator for characterizing the spatiotemporal distribution of landslide-prone areas in order to establish a global rainfall-triggered landslide climatology. This study characterizes the variability of satellite precipitation data and reported landslide activity at the global scale in order to improve landslide cataloging and attempt to quantify landslide triggering at daily, monthly, and yearly time scales.

The WGEW network is the densest rain gauge network in the PR coverage area for watersheds greater than 10 km super(2). It consists of 88 weighing rain gauges within a 149-km super(2) area. On average, approximately 10 gauges can be found in each PR field of view ( similar to 5-km diameter). All gauges are very well synchronized with 1-min reporting intervals. This allows generating very-high-temporal-resolution rain rate fields and obtaining accurate estimates of the area-average rain rate for the entire watershed and for a single PR field of view. In this study, instantaneous rain rate fields from the PR and the spatially interpolated gauge measurements (on a 100 m 100 m grid, updated every 1 min) are compared for all TRMM overpasses in which the PR recorded rain within the WGEW boundaries (25 overpasses during 1999-2010). The results indicate very good agreement between the fields with low bias values (0.9). The correlation is high at overpass time but the peak occurs several minutes after the overpass, which can be explained by the fact that it takes several minutes for the raindrops to reach the gauge from the time they are observed by the PR. The correlation improves with the new version of the TRMM algorithm (V7). The study includes assessment of the accuracy of the reference products.

In this study, the dampening impact of urban trees on the UHI during an extreme heat wave in the Washington, D.C., and Baltimore, Maryland, metropolitan area is examined by incorporating trees, soil, and grass into the coupled Weather Research and Forecasting model and an urban canopy model (WRF-UCM). By parameterizing the effects of these natural surfaces alongside roadways and buildings, the modified WRF-UCM is used to investigate how urban trees, soil, and grass dampen the UHI. The modified model was run with 50% tree cover over urban roads and a 10% decrease in the width of urban streets to make space for soil and grass alongside the roads and buildings. Results show that, averaged over all urban areas, the added vegetation decreases surface air temperature in urban street canyons by 4.1 K and road-surface and building-wall temperatures by 15.4 and 8.9 K, respectively, as a result of tree shading and evapotranspiration. These temperature changes propagate downwind and alter the temperature gradient associated with the Chesapeake Bay breeze and, therefore, alter the strength of the bay breeze. The impact of building height on the UHI shows that decreasing commercial building heights by 8 m and residential building heights by 2.5 m results in up to 0.4-K higher daytime surface and near-surface air temperatures because of less building shading and up to 1.2-K lower nighttime temperatures because of less longwave radiative trapping in urban street canyons.

Due to the short interval between analyses, EnKF perturbations primarily contain instabilities related to fast weather variability. To isolate slower, coupled instabilities that would be more suitable for seasonal prediction, an empirical linear operator for seasonal time-scales (i.e. several months) is formulated using a causality hypothesis; then, the most unstable mode from the linear operator is extracted for seasonal time-scales. It is shown that the flow-dependent operator represents nonlinear integration results better than a conventional empirical linear operator static in time. Through 20 years of retrospective seasonal predictions, it is shown that the skill of forecasting equatorial SST anomalies using the FESV is systematically improved over that using Conventional ESV (CESV). For example, the correlation skill of the NINO3 SST index using FESV is higher, by about 0.1, than that of CESV at 8-month leads. In addition, the forecast skill improvement is significant over the locations where the correlation skill of conventional methods is relatively low, indicating that the FESV is effective where the initial uncertainty is large.

We measured the beta -factors of goethite FeO(OH), potassium-jarosite KFe (sub 3) (SO (sub 4) ) (sub 2) (OH) (sub 6) , and hydronium-jarosite (H (sub 3) O)Fe (sub 3) (SO (sub 4) ) (sub 2) (OH) (sub 6) , by Nuclear Resonant Inelastic X-ray Scattering (NRIXS, also known as Nuclear Resonance Vibrational Spectroscopy - NRVS or Nuclear Inelastic Scattering - NIS) at the Advanced Photon Source. These measurements were made on synthetic minerals enriched in (super 57) Fe. A new method (i.e., the general moment approach) is presented to calculate beta -factors from the moments of the NRIXS spectrum S(E). The first term in the moment expansion controls iron isotopic fractionation at high temperature and corresponds to the mean force constant of the iron bonds, a quantity that is readily measured and often reported in NRIXS studies. The mean force constants of goethite, potassium-jarosite, and hydronium-jarosite are 314+ or -14, 264+ or -12, and 310+ or -14 N/m, respectively (uncertainties include statistical and systematic errors). The general moment approach gives (super 56) Fe/ (super 54) Fe beta -factors of 9.7, 8.3, and 9.5 ppm at 22 degrees C for these minerals. The beta -factor of goethite measured by NRIXS is larger than that estimated by combining results from laboratory exchange experiments and calculations based on electronic structure theory. Similar issues have been identified previously for other pairs of mineral-aqueous species, which could reflect inadequacies of approaches based on electronic structure theory to calculate absolute beta -factors (differences in beta -factors between aqueous species may be more accurate) or failure of laboratory experiments to measure mineral-fluid equilibrium isotopic fractionation at low temperature.

Pollen stratigraphy generally matches the New England pollen zones identified by Deevey (1939) and Davis (1969), with boreal genera (Picea, Abies) present during the late Pleistocene yielding to a mixed Pinus, Quercus and Tsuga forest in the early Holocene. Lake Minnewaska sediments record the Younger Dryas and possibly the 8.2 cal kyr BP climatic events in pollen and sediment chemistry along with an approximately 1400 cal yr interval of wet conditions (increasing Tsuga and declining Quercus) centered about 6400 cal yr BP. Both Minnewaska and Mohonk reveal a protracted drought interval in the middle Holocene, approximately 5700-4100 cal yr BP, during which Pinus rigida colonized the watershed, lake levels fell, and frequent fires led to enhanced hillslope erosion. Together, the records show at least three wet-dry cycles throughout the Holocene and both similarities and differences to climate records in New England and central New York. Drought intervals raise concerns for water resources in the New York City metropolitan area and may reflect a combination of enhanced La Nina, negative phase NAO, and positive phase PNA climatic patterns and/or northward shifts of storm tracks.

However, searching, accessing, and processing heterogeneous data from different sources are very time-consuming tasks. There is lack of a comprehensive visual platform to acquire distributed and heterogeneous scientific data and to render processed images from a single accessing point for climate studies. This paper documents the design and implementation of a Web-based visual, interoperable, and scalable platform that is able to access climatological fields from models, satellites, and ground stations from a number of data sources using Google Earth (GE) as a common graphical interface. The development is based on the TCP/IP protocol and various data sharing open sources, such as OPeNDAP, GDS, Web Processing Service (WPS), and Web Mapping Service (WMS). The visualization capability of integrating various measurements into GE extends dramatically the awareness and visibility of scientific results. Using embedded geographic information in the GE, the designed system improves our understanding of the relationships of different elements in a four-dimensional domain. The system enables easy and convenient synergistic research on a virtual platform for professionals and the general public, greatly advancing global data sharing and scientific research collaboration.

AN - 1312656064; 15505 AB - PURPOSE: The continuation of the National Aeronautics and Space Administration (NASA) Sounding Rockets Program (SRP) at Poker Flat Research Range (PFRR), outside of Fairbanks, Alaska is assessed. Owned and operated by the University of Alaska Fairbanks since 1968, the PFRR is a launch facility for sounding rockets, which carry scientific instruments into regions of the upper atmosphere and space. The primary types of missions conducted by NASA at PFRR are in partnership with university scientists who study the earth's atmosphere and its interaction with the space environment. The PFRR is located northeast of the unincorporated village of Chatanika, Alaska and consists of 5,200 acres of land that house rocket and support facilities, launch pads, and tracking infrastructure. Directly north of the PFRR facility are its downrange flight zones, over which rockets are launched and within which spent stages and payloads impact the ground. Within these flight zones are Steese National Conservation Area and White Mountain National Recreational Area, and the Arctic and Yukon Flats National Wildlife Refuges. Historically, the Bureau of Land Management and the Fish and Wildlife Service have issued special-use authorizations and agreements for impact of rockets and recovery operations on these lands. This draft EIS tiers from the programmatic 2000 SRP final supplemental EIS and considers five alternatives for continued operations at PFRR. Under the No Action Alternative, the SRP would continue in its present form and no significant efforts would be taken to recover spent stages unless desired for programmatic reasons, and payloads would only be recovered if required by the scientists. Alternative 1 would include enhanced efforts to locate new and existing spent stages and payloads within the PFRR flight corridor. Some items or parts thereof could be left in the field if the landowners agree that attempted recovery could cause more damage to the environment than leaving it in place. Alternative 2 is the same as Alternative 1, except maximum practicable effort would be exerted to fully recover newly expended and existing spent stages and payloads if it is determined that they can be recovered safely, even if the efforts result in longer-term recovery-related environmental impacts. Alternative 3 is the same as Alternative 1, except trajectories of future sounding rocket missions would be restricted such that planned impacts would not be permitted within designated Wild and Scenic River corridors. The restriction would be an extension of the existing prohibition on having planned impacts within Mollie Beattie Wilderness Area. Alternative 4 would include maximum cleanup search and recovery as well as the restrictions on flight trajectories. Under all alternatives, the anticipated launch schedule at PFRR would remain an average of four launches annually. POSITIVE IMPACTS: Mitigation measures and recovery of spent stages and payloads would protect sensitive environments while NASA continues to obtain the requisite earth and space science data afforded by high-latitude sounding rocket launches in support of its science and educational missions. NEGATIVE IMPACTS: Routine operations would continue to have minor adverse impacts with respect to air quality and noise, and launch operations would require the use of small quantities of potentially hazardous materials, some of which would land within downrange properties. Under Alternatives 1 and 3, the additional efforts to recover flight hardware could result in isolated soil disturbances; however, all recovery efforts would be conducted in an environmentally sensitive manner. Any adverse impacts from launch operations on wildlife would be similar for all alternatives and would be local, short-term, and negligible.

We use 13 global biomass burning emission estimates, including the widely used Global Fire Emission Database (GFED) monthly and daily versions, Fire Radiative Power (FRP)-based Quick Fire Emission Data set QFED, and 11 calculated emissions from different combinations of burned area based on the Moderate Resolution Imaging Spectroradiometer (MODIS) products, effective fuel load, and species emission factors as alternative inputs to the global Goddard Chemistry Aerosol Radiation and Transport (GOCART) model. The resultant simulated aerosol optical depth (AOD) and its spatial distribution are compared to AOD snapshots measured by the MODIS instrument for 124 fire events occurring between 2006 and 2007. This comparison exposes the regional biases of each emission option. GOCART average fire AOD values compare best to MODIS-measured AOD when the daily GFED inventory is used as input to GOCART. Even though GFED-based emission options provide the lowest emissions in the tropics, GFED-based GOCART AOD compares best with MODIS AOD in tropical cases. Fire-counts-based emission options give the largest emission estimates in the boreal regions, and the model performs best at higher latitudes with these inputs when compared to MODIS. Comparison of total annual BB emissions by all inventories suggests that burned area estimates are usually the largest source of disagreement. It is also shown that the quantitative relationship between BB aerosol emission rate and model-simulated AOD is related to the horizontal plume dispersion, which can be approximated by the wind speed in the planetary boundary layer in most cases. Thus, given average wind speed of the smoke plume environment, MODIS-measured AOD can provide a constraint to the strength of BB sources at the level of individual plumes.

Dust emission at 12 and/or 22 mu m (T (sub dust) approximately 300 and/or approximately 150 K) traces events in the terrestrial planet zones; its existence implies replenishment by evaporation of comets or collisions of asteroids, possibly stirred by larger planets. Of the 591 planetary systems (728 extrasolar planets) in the Exoplanet Encyclopaedia as of 2012 January 31, 350 are robustly detected by WISE at > or =5sigma level. We perform detailed photosphere subtraction using tools developed for Spitzer data and visually inspect all the WISE images to confirm bona fide point sources. We find nine planet-bearing stars show dust excess emission at 12 and/or 22 mu m at > or =3sigma level around young, main-sequence, or evolved giant stars. Overall, our results yield an excess incidence of approximately 2.6% for stars of all evolutionary stages, but approximately 1% for planetary debris disks around main-sequence stars. Besides recovering previously known warm systems, we identify one new excess candidate around the young star UScoCTIO 108. Copyright (Copyright) 2012. The American Astronomical Society.

Complementing the cryospheric instrument payload were four in situ atmospheric sampling instruments integrated onboard to measure trace gas concentrations of CO sub(2), CO, N sub(2)O, CH sub(4), water vapor and various VOCs (Volatile Organic Compounds). This paper examines two plumes encountered at high altitude (12 km) during the campaign; one during a southbound transit flight (13 degree S) and the other at 86 degree S over Antarctica. The data presented are especially significant as the Southern Hemisphere is heavily under-sampled during the austral spring, with few if any high-resolution airborne observations of atmospheric gases made over Antarctica. Strong enhancements of CO, CH sub(4), N sub(2)O, CHCl sub(3), OCS, C sub(2)H sub(6), C sub(2)H sub(2) and C sub(3)H sub(8) were observed in the two intercepted air masses that exhibited variations in VOC composition suggesting different sources. The transport model FLEXPART showed that the 13 degree S plume contained predominately biomass burning emissions originating from Southeast Asia and South Africa, while both anthropogenic and biomass burning emissions were observed at 86 degree S with South America and South Africa as indicated source regions. The data presented here show evidence that boundary layer pollution is transported from lower latitudes toward the upper troposphere above the South Pole, which may not have been observed in the past.

N1 - Last updated - 2012-09-13 ER - TY - JOUR T1 - Toward a combined SAGE II-HALOE aerosol climatology: an evaluation of HALOE version 19 stratospheric aerosol extinction coefficient observations AN - 1093471492; 17188427 AB - Herein, the Halogen Occultation Experiment (HALOE) aerosol extinction coefficient data is evaluated in the low aerosol loading period after 1996 as the first necessary step in a process that will eventually allow the production of a combined HALOE/SAGE II (Stratospheric Aerosol and Gas Experiment) aerosol climatology of derived aerosol products including surface area density. Based on these analyses, it is demonstrated that HALOE's 3.46 mu m is of good quality above 19 km and suitable for scientific applications above that altitude. However, it is increasingly suspect at lower altitudes and should not be used below 17 km under any circumstances after 1996. The 3.40 mu m is biased by about 10% throughout the lower stratosphere due to the failure to clear NO sub(2) but otherwise appears to be a high quality product down to 15 km. The 2.45 and 5.26 mu m aerosol extinction coefficient measurements are clearly biased and should not be used for scientific applications after the most intense parts of the Pinatubo period. Many of the issues in the aerosol data appear to be related to either the failure to clear some interfering gas species or doing so poorly. For instance, it is clear that the 3.40 mu m aerosol extinction coefficient measurements can be improved through the inclusion of an NO sub(2) correction and could, in fact, end up as the highest quality overall HALOE aerosol extinction coefficient measurement. It also appears that the 2.45 and 5.26 mu m channels may be improved by updating the Upper Atmosphere Pilot Database which is used as a resource for the removal of gas species otherwise not available from direct HALOE measurements. Finally, a simple model to demonstrate the promise of mixed visible/infrared aerosol extinction coefficient ensembles for the retrieval of bulk aerosol properties demonstrates that a combined HALOE/SAGE II aerosol climatology is feasible and may represent a substantial improvement over independently derived data sets.

Owing to the unprecedented accuracy and long-term stability of its radiometric calibration, SeaWiFS measurements exhibit minimal uncertainty with respect to sensor calibration. In this study, we take advantage of this well-calibrated set of measurements by applying a newly-developed aerosol optical depth (AOD) retrieval algorithm over land and ocean to investigate the distribution of AOD, and to identify emerging patterns and trends in global and regional aerosol loading during its 13-yr mission. Our correlation analysis between climatic indices (such as ENSO) and AOD suggests strong relationships for Saharan dust export as well as biomass-burning activity in the tropics, associated with large-scale feedbacks. The results also indicate that the averaged AOD trend over global ocean is weakly positive from 1998 to 2010 and comparable to that observed by MODIS but opposite in sign to that observed by AVHRR during overlapping years. On regional scales, distinct tendencies are found for different regions associated with natural and anthropogenic aerosol emission and transport. For example, large upward trends are found over the Arabian Peninsula that indicate a strengthening of the seasonal cycle of dust emission and transport processes over the whole region as well as over downwind oceanic regions. In contrast, a negative-neutral tendency is observed over the desert/arid Saharan region as well as in the associated dust outflow over the north Atlantic. Additionally, we found decreasing trends over the eastern US and Europe, and increasing trends over countries such as China and India that are experiencing rapid economic development. In general, these results are consistent with those derived from ground-based AERONET measurements.

The ARTP presented here gives the time-dependent temperature response in four latitude bands (90-28 degree S, 28 degree S-28 degree N, 28-60 degree N and 60-90 degree N) as a function of emissions based on the forcing in those bands caused by the emissions. It is based on a large set of simulations performed with a single atmosphere-ocean climate model to derive regional forcing/response relationships. Here I evaluate the robustness of those relationships using the forcing/response portion of the ARTP to estimate regional temperature responses to the historic aerosol forcing in three independent climate models. These ARTP results are in good accord with the actual responses in those models. Nearly all ARTP estimates fall within plus or minus 20% of the actual responses, though there are some exceptions for 90-28 degree S and the Arctic, and in the latter the ARTP may vary with forcing agent. However, for the tropics and the Northern Hemisphere mid-latitudes in particular, the plus or minus 20% range appears to be roughly consistent with the 95% confidence interval. Land areas within these two bands respond 39-45% and 9-39% more than the latitude band as a whole. The ARTP, presented here in a slightly revised form, thus appears to provide a relatively robust estimate for the responses of large-scale latitude bands and land areas within those bands to inhomogeneous radiative forcing and thus potentially to emissions as well. Hence this metric could allow rapid evaluation of the effects of emissions policies at a finer scale than global metrics without requiring use of a full climate model.

The presence of allophane in TES models indicates that the martian surface experienced low-temperature chemical weathering at low water-to-rock ratios and mildly acidic to neutral pH on regional scales. The allophane and gel may be ancient and preserved by a persistently dry martian climate. Alternatively, evidence for recent ground ice in these regions suggests that pedogenic processes causing the formation of poorly-crystalline aluminosilicates could be late Amazonian in age and may be active today. While previous models have suggested that global-scale acidic weathering has occurred on Mars for the past 3.5 billion years, the presence of allophane indicates that acidic weathering was not occurring in these low-albedo regions and that mildly acidic to neutral weathering has been an important regional-scale weathering process on the martian surface.

N1 - Last updated - 2012-09-04 ER - TY - JOUR T1 - The O/OREOS Mission: First Science Data from the Space Environment Viability of Organics (SEVO) Payload AN - 1827882603; PQ0003681184 AB - We report the first science results from the Space Environment Viability of Organics (SEVO) payload aboard the Organism/Organic Exposure to Orbital Stresses (O/OREOS) free-flying nanosatellite, which completed its nominal spaceflight mission in May 2011 but continues to acquire data biweekly. The SEVO payload integrates a compact UV-visible-NIR spectrometer, utilizing the Sun as its light source, with a 24-cell sample carousel that houses four classes of vacuum-deposited organic thin films: polycyclic aromatic hydrocarbon (PAH), amino acid, metalloporphyrin, and quinone. The organic films are enclosed in hermetically sealed sample cells that contain one of four astrobiologically relevant microenvironments. Results are reported in this paper for the first 309 days of the mission, during which the samples were exposed for 2210h to direct solar illumination (1080kJ/cm2 of solar energy over the 124-2600nm range). Transmission spectra (200-1000nm) were recorded for each film, at first daily and subsequently every 15 days, along with a solar spectrum and the dark response of the detector array. Results presented here include eight preflight and 16 in-flight spectra of eight SEVO sample cells. Spectra from the PAH thin film in a water-vapor-containing microenvironment indicate measurable change due to solar irradiation in orbit, while three other nominally water-free microenvironments show no appreciable change. The quinone anthrarufin showed high photostability and no significant spectroscopically measurable change in any of the four microenvironments during the same period. The SEVO experiment provides the first in situ real-time analysis of the photostability of organic compounds and biomarkers in orbit.

We have performed a first global-scale analysis of the impact of water withdrawals on water storage variations, using the global water resources and use model WaterGAP. This required estimation of fractions of total water withdrawals from groundwater, considering five water use sectors. According to our assessment, the source of 35% of the water withdrawn worldwide (4300 km (super 3) /year during 1998-2002) is groundwater. Groundwater contributes 42%, 36% and 27% of water used for irrigation, households and manufacturing, respectively, while we assume that only surface water is used for livestock and for cooling of thermal power plants. Consumptive water use was 1400 km (super 3) /year during 1998-2002. It is the sum of the net abstraction of 250 km (super 3) /year of groundwater (taking into account evapotranspiration and return flows of withdrawn surface water and groundwater) and the net abstraction of 1150 km (super 3) /year of surface water. Computed net abstractions indicate, for the first time at the global scale, where and when human water withdrawals decrease or increase groundwater or surface water storage. In regions with extensive surface water irrigation, such as Southern China, net abstractions from groundwater are negative, i.e. groundwater is recharged by irrigation. The opposite is true for areas dominated by groundwater irrigation, such as in the High Plains aquifer of the central USA, where net abstraction of surface water is negative because return flow of withdrawn groundwater recharges the surface water compartments. In intensively irrigated areas, the amplitude of seasonal total water storage variations is generally increased due to human water use; however, in some areas, it is decreased. For the High Plains aquifer and the whole Mississippi basin, modeled groundwater and total water storage variations were compared with estimates of groundwater storage variations based on groundwater table observations, and with estimates of total water storage variations from the GRACE satellites mission. Due to the difficulty in estimating area-averaged seasonal groundwater storage variations from point observations of groundwater levels, it is uncertain whether WaterGAP underestimates actual variations or not. We conclude that WaterGAP possibly overestimates water withdrawals in the High Plains aquifer where impact of human water use on water storage is readily discernible based on WaterGAP calculations and groundwater observations. No final conclusion can be drawn regarding the possibility of monitoring water withdrawals in the High Plains aquifer using GRACE. For the less intensively irrigated Mississippi basin, observed and modeled seasonal groundwater storage reveals a discernible impact of water withdrawals in the basin, but this is not the case for total water storage such that water withdrawals at the scale of the whole Mississippi basin cannot be monitored by GRACE.

In particular, complex organic aerosols produced in atmospheres containing C, N, O, and H, like that of Titan, could be a source of prebiotic molecules. In this work, aerosols produced in a Titan atmosphere simulation experiment with enhanced CO (N (sub 2) /CH (sub 4) /CO gas mixtures of 96.2%/2.0%/1.8% and 93.2%/5.0%/1.8%) were found to contain 18 molecules with molecular formulae that correspond to biological amino acids and nucleotide bases. Very high-resolution mass spectrometry of isotopically labeled samples confirmed that C (sub 4) H (sub 5) N (sub 3) O, C (sub 4) H (sub 4) N (sub 2) O (sub 2) , C (sub 5) H (sub 6) N (sub 2) O (sub 2) , C (sub 5) H (sub 5) N (sub 5) , and C (sub 6) H (sub 9) N (sub 3) O (sub 2) are produced by chemistry in the simulation chamber. Gas chromatography-mass spectrometry (GC-MS) analyses of the non-isotopic samples confirmed the presence of cytosine (C (sub 4) H (sub 5) N (sub 3) O), uracil (C (sub 5) H (sub 4) N (sub 2) O (sub 2) ), thymine (C (sub 5) H (sub 6) N (sub 2) O (sub 2) ), guanine (C (sub 5) H (sub 5) N (sub 5) O), glycine (C (sub 2) H (sub 5) NO (sub 2) ), and alanine (C (sub 3) H (sub 7) NO (sub 2) ). Adenine (C (sub 5) H (sub 5) N (sub 5) ) was detected by GC-MS in isotopically labeled samples. The remaining prebiotic molecules were detected in unlabeled samples only and may have been affected by contamination in the chamber. These results demonstrate that prebiotic molecules can be formed by the high-energy chemistry similar to that which occurs in planetary upper atmospheres and therefore identifies a new source of prebiotic material, potentially increasing the range of planets where life could begin.

The charging of bulk materials with planar surfaces by SEE with electron impact appears to be well understood with theoretical expressions as well as by experimental techniques. However, the charging of submicron/micron-size dust grains by SEE with sufficiently high-energy electrons is a complex process, and is a function of electron energies, the electron current, and the grain size, and the charge or the surface potential. Development of viable theoretical models and acquisition of experimental data for charging properties of micron-size dust grains are still in the early stages. This paper focuses on SEE charging properties of individual micron-size dust grains by low-energy electron impact, obtained from laboratory measurements on an experimental facility based on an electrodynamic balance. The measurements of SEE yields of positively charged dust grains indicate the yields increase with decreasing grain size and the equilibrium surface potentials showing generally linear size dependence. These experimental results are generally in agreement with several independent experimental and analytical model studies in the literature, with the exception of a recently published paper which is in fundamental conflict with our studies as well as with several other experimental and theoretical studies. The sources and causes of this conflict are critically examined and discussed in this paper. Copyright (Copyright) 2012. The American Astronomical Society. All rights reserved.

For the Distributed Model Intercomparison Project - Phase 2 Western basins, we assimilate satellite-based fractional snow cover area (fSCA) from the Moderate Resolution Imaging Spectroradiometer, or MODIS, into the National Weather Service (NWS) SNOW-17 model. This model is coupled with the NWS Sacramento Heat Transfer (SAC-HT) model inside the National Aeronautics and Space Administration's (NASA) Land Information System. SNOW-17 computes fSCA from snow water equivalent (SWE) values using an areal depletion curve. Using a direct insertion, we assimilate fSCAs in two fully distributed ways: (1) we update the curve by attempting SWE preservation, and (2) we reconstruct SWEs using the curve. The preceding are refinements of an existing simple, conceptually guided NWS algorithm. Satellite fSCA over dense forests inadequately accounts for below-canopy snow, degrading simulated streamflow upon assimilation during snowmelt. Accordingly, we implement a below-canopy allowance during assimilation. This simplistic allowance and direct insertion are found to be inadequate for improving calibrated results, still degrading them as mentioned above. However, for streamflow volume for the uncalibrated runs, we obtain: (1) substantial to major improvements (64-81%) as a percentage of the control run residuals (or distance from observations), and (2) minor improvements (16-22%) as a percentage of observed values. We highlight the need for detailed representations of canopy-snow optical radiative transfer processes in mountainous, dense forest regions if assimilation-based improvements are to be seen in calibrated runs over these areas. Key Points * Unaccounted below-canopy snow extent important * Below-canopy snow accounting improves streamflow simulations * Models should incorporate detailed snow and vegetation representations JF - Water Resources Research AU - Yatheendradas, Soni AU - Lidard, Christa DPeters AU - Koren, Victor AU - Cosgrove, Brian A AU - De Goncalves, Luis GG AU - Smith, Michael AU - Geiger, Jim AU - Cui, Zhengtao AU - Borak, Jordan AU - Kumar, Sujay V AU - Toll, David L AU - Riggs, George AU - Mizukami, Naoki AD - Earth System Science Interdisciplinary Center,College Park, Maryland,USA., soni.yatheendradas-1@nasa.gov Y1 - 2012/09// PY - 2012 DA - Sep 2012 SP - [np] PB - American Geophysical Union, 2000 Florida Ave., N.W.

For the first time we report on ground-based lidar observations of the same event from every continent in the Northern Hemisphere, taking advantage of the synergy between global lidar networks such as EARLINET, MPLNET and NDACC with independent lidar groups and satellite CALIPSO to track the evolution of the stratospheric aerosol layer in various parts of the globe. The globally averaged aerosol optical depth (AOD) due to the stratospheric volcanic aerosol layers was of the order of 0.018 + or - 0.009 at 532 nm, ranging from 0.003 to 0.04. Compared to the total column AOD from the available collocated AERONET stations, the stratospheric contribution varied from 2% to 23% at 532 nm.

Launched on 27 November 1997, TRMM is a joint U.S.-Japan satellite mission to provide the first detailed and comprehensive dataset of the four-dimensional distribution of rainfall and latent heating over vastly undersampled tropical and subtropical oceans and continents (40 degree S-40 degree N). Over the past 14 years, TRMM has been a major data source for meteorological, hydrological, and other research and application activities around the world. This short article describes how the NASA Goddard Earth Sciences Data and Information Services Center (GES DISC) provides TRMM archive and nearreal- time precipitation datasets and services for research and applications. TRMM data consist of orbital data from TRMM instruments at the sensor's resolution, gridded data at a range of spatial and temporal resolutions, subsets, ground-based instrument data, and ancillary data. Data analysis, display, and delivery are facilitated by the following services: (1) Mirador (data search and access); (2) TOVAS (TRMM Online Visualization and Analysis System); (3) OPeNDAP (Opensource Project for a Network Data Access Protocol); (4) GrADS Data Server (GDS); and (5) Open Geospatial Consortium (OGC) Web Map Service (WMS) for the GIS community. Precipitation data application services are available to support a wide variety of applications around the world. Future plans include enhanced and new services to address data-related issues from the user community. Meanwhile, the GES DISC is preparing for the Global Precipitation Measurement (GPM) mission, which is scheduled for launch in 2014.

Here we describe the approach used to identify, characterize, and assess environmental risks to the landing and rover surface operations. Novel entry, descent, and landing approaches will be used to accurately deliver the 900-kg rover, including the ability to sense and "fly out" deviations from a best-estimate atmospheric state. A joint engineering and science team developed methods to estimate the range of potential atmospheric states at the time of arrival and to quantitatively assess the spacecraft's performance and risk given its particular sensitivities to atmospheric conditions. Numerical models are used to calculate the atmospheric parameters, with observations used to define model cases, tune model parameters, and validate results. This joint program has resulted in a spacecraft capable of accessing, with minimal risk, the four finalist sites chosen for their scientific merit. The capability to operate the landed rover over the latitude range of candidate landing sites, and for all seasons, was verified against an analysis of surface environmental conditions described here. These results, from orbital and model data sets, also drive engineering simulations of the rover's thermal state that are used to plan surface operations.

Pre-dried soils (500 degrees C) were bombarded with 1.1 keV protons and deuterons and provide unambiguous evidence for the formation of OH or OD in both samples. This hypothesis further predicts the formation of hydroxyl (OH) on other airless planetary/asteroidal bodies, with a sufficient solar-wind flux. Deuteron implantation of unaltered lunar soils and a heat-treated plagioclase specimen cause simultaneous OH depletion and OD formation. Ion bombardment of lunar soils simulates the dynamic process of hydroxyl formation and may also deplete intrinsic OH, thereby effectively contributing to the day/night, diurnal variability of OH reported by Sunshine et al. (2009). Our results emphasize the need to use lunar soils with space-weathered exteriors in laboratory simulations of the solar wind. Infrared spectra of hydrogen ion-beam implanted soils are similar to spectra obtained at RELAB (Brown Univ.) and to those observed by remote sensing confirming the solar-wind hypothesis.

In recent years, several emerging technology breakthroughs have enabled unprecedented device performance when nanomaterials and devices are integrated at the converging length scales. For example, metal nanowires (NWs) incorporated in micro- or nanofluidic channels create plasmonic surface enhancement for biological and chemical sensing to at least a twofold increase in magnitude. Another exciting development is that nanomaterial assemblies are integrated with waveguides and optical fibers to improve light interactions for energy conversion in photosynthesis reactions and solar energy storage. These materials are optimized for electrical as well as optical properties in the devices. Nanostructured carbonaceous materials, semiconductor metal oxides, polymers, and metal NWs enable next-generation solar and wind energy harvesting, chemical and electrical storage, stretchable and flexible electronics, transparent electrodes, and displays.

On 22 January 2007, the C3VP campaign executed an intensive observation period to sample widespread snowfall that occurred as a midlatitude cyclone tracked along the U.S.-Canadian border. Surface air temperature and precipitation measurements, combined with aircraft measurement of hydrometeor content and size distribution, are used to examine various assumptions and parameterizations included within four bulk water microphysics schemes available within the Weather Research and Forecasting Model (WRF). In a simulation of the 22 January 2007 event, WRF forecasts reproduced the overall precipitation pattern observed during aircraft sampling, allowing for a comparison between C3VP measurements and microphysics scheme assumptions. Single-moment schemes that provide flexibility in size distribution parameters as functions of temperature can represent much of the vertical variability observed in aircraft data, but variability is reduced in an environment where the simulated temperature profile is nearly isothermal. Double-moment prediction of total number concentration may improve the representation of ice crystal aggregation. Inclusion of both temperature dependence on distribution parameters and variability in mass-diameter or diameter-fall speed relationships suggest a means of improving upon single-moment predictions.

The first crews of the International Space Station (ISS) used the "interim resistive exercise device" (iRED), which allowed loads of up to 297 lb sub(f) (or 1337 N) but provided little protection of bone or no greater protection than aerobic exercise. In 2008, the Advanced Resistive Exercise Device (ARED), which allowed absolute loads of up to 600 lb sub(f) (1675 N), was launched to the ISS. We report dietary intake, bone densitometry, and biochemical markers in 13 crewmembers on ISS missions from 2006 to 2009. Of these 13, 8 had access to the iRED and 5 had access to the ARED. In both groups, bone-specific alkaline phosphatase tended to increase during flight toward the end of the mission (p = 0.06) and increased 30 days after landing (p<0.001). Most markers of bone resorption were also increased in both groups during flight and 30 days after landing (p<0.05). Bone densitometry revealed significant interactions (time and exercise device) for pelvis bone mineral density (BMD) and bone mineral content (p<0.01), hip femoral neck BMD (p<0.05), trochanter BMD (p<0.05), and total hip BMD (p<0.05). These variables were unchanged from preflight only for ARED crewmembers, who also returned from flight with higher percent lean mass and lower percent fat mass. Body mass was unchanged after flight in both groups. All crewmembers had nominal vitamin D status (75 plus or minus 17 nmol/L) before and during flight. These data document that resistance exercise, coupled with adequate energy intake (shown by maintenance of body mass determined by dual-energy X-ray absorptiometry [DXA]) and vitamin D, can maintain bone in most regions during 4- to 6-month missions in microgravity. This is the first evidence that improving nutrition and resistance exercise during spaceflight can attenuate the expected BMD deficits previously observed after prolonged missions.

The fortuitous occurrence of large wildfire episodes in Northern California allowed for studies of fire emissions, their composition, and their interactions with rural and urban air. Relative to CO, emissions of HCN were shown to vary non-linearly with fire characteristics while those of CH3CN were nearly unchanged, making the latter a superior quantitative tracer of biomass combustion. Although some fire plumes over California contained little NOx and virtually no O3 enhancement, others contained ample VOCs and sufficient NOx, largely from urban influences, to result in significant ozone formation. The highest observed O3 mixing ratios (170 ppb) were also in fire-influenced urban air masses. Attempts to simulate these interactions using CMAQ, a high-resolution state of the art air quality model, were only minimally successful and indicated several shortcomings in simulating fire emission influences on urban smog formation. A variety of secondary oxidation products (e.g. O3, PAN, HCHO) were substantially underestimated in fire-influenced air masses. Available data involving fire plumes and anthropogenic pollution interactions are presently quite sparse and additional observational and mechanistic studies are needed.

Such models are known as coupled chemistry-climate models (CCMs). Although developed from common principles and subject to the same boundary conditions, simulated ozone time series vary among models for scenarios for ozone depleting substances (ODSs) and greenhouse gases. Photochemical processes control the upper stratospheric ozone level, and there is broad agreement among CCMs in that ozone increases as ODSs decrease and temperature decreases due to greenhouse gas increase. There are quantitative differences in the ozone sensitivity to chlorine and temperature. We obtain insight into differences in sensitivity by examining the relationship between the upper stratospheric seasonal cycles of ozone and temperature as produced by fourteen CCMs. All simulations conform to expectation in that ozone is less sensitive to temperature when chlorine levels are highest because chlorine catalyzed loss is nearly independent of temperature. Analysis reveals differences in simulated temperature, ozone and reactive nitrogen that lead to differences in the relative importance of ozone loss processes and are most obvious when chlorine levels are close to background. Differences in the relative importance of loss processes underlie differences in simulated sensitivity of ozone to composition change. This suggests 1) that the multimodel mean is not a best estimate of the sensitivity of upper stratospheric ozone to changes in ODSs and temperature; and 2) that the spread of values is not an appropriate measure of uncertainty.

We found 677 suitable overpasses, and a CALIPSO bias of -13% relative to AERONET for the entire data set; the corresponding absolute bias is -0.029, and the standard deviation of the mean (SDOM) is 0.014. Consequently, the null hypothesis is rejected at the 97% confidence level, indicating a statistically significant difference between the datasets. However, if we omit CALIPSO columns that contain dust from our analysis, the relative and absolute biases are reduced to -3% and -0.005 with a standard error of 0.016 for 449 overpasses, and the statistical confidence level for the null hypothesis rejection is reduced to 27%. We also analyzed the results according to the six CALIPSO aerosol subtypes and found relative and absolute biases of -29% and -0.1 for atmospheric columns that contain the dust subtype exclusively, but with a relatively high correlation coefficient of R = 0.58; this indicates the possibility that the assumed lidar ratio (40 sr) for the CALIPSO dust retrievals is too low. Hence, we used the AERONET size distributions, refractive indices, percent spheres, and forward optics code for spheres and spheroids to compute a lidar ratio climatology for AERONET sites located in the dust belt. The highest lidar ratios of our analysis occur in the non-Sahel regions of Northern Africa, where the median lidar ratio at 0.532 mu m is 55.4 sr for 229 retrievals. Lidar ratios are somewhat lower in the African Sahel (49.7 sr for 929 retrievals), the Middle East (42.6 sr for 489 retrievals), and Kanpur, India (43.8 sr for 67 retrievals). We attribute this regional variability in the lidar ratio to the regional variability of the real refractive index of dust, as these two parameters are highly anti-correlated (correlation coefficients range from -0.51 to -0.85 for the various regions). The AERONET refractive index variability is consistent with the variability of illite concentration in dust across the dust belt.

Kepler's supernova remnant, the result of a Type Ia supernova, shows evidence for an interaction with a dense circumstellar medium (CSM), suggesting a single-degenerate progenitor system. We present 7.5-38 mu m infrared (IR) spectra of the remnant, obtained with the Spitzer Space Telescope, dominated by emission from warm dust. Broad spectral features at 10 and 18 mu m, consistent with various silicate particles, are seen throughout. These silicates were likely formed in the stellar outflow from the progenitor system during the asymptotic giant branch stage of evolution, and imply an oxygen-rich chemistry. In addition to silicate dust, a second component, possibly carbonaceous dust, is necessary to account for the short-wavelength Infrared Spectrograph and Infrared Array Camera data. This could imply a mixed chemistry in the atmosphere of the progenitor system. However, non-spherical metallic iron inclusions within silicate grains provide an alternative solution. Models of collisionally heated dust emission from fast shocks (>1000 km s super(-1)) propagating into the CSM can reproduce the majority of the emission associated with non-radiative filaments, where dust temperatures are ~80-100 K, but fail to account for the highest temperatures detected, in excess of 150 K. We find that slower shocks (a few hundred km s super(-1)) into moderate density material (n sub(0) ~ 50-250 cm super(-3)) are the only viable source of heating for this hottest dust. We confirm the finding of an overall density gradient, with densities in the north being an order of magnitude greater than those in the south.

Nevertheless, few studies address the biological dissolution mechanism(s) of FePO (sub 4) .2H (sub 2) O. This paper reports steady-state dissolution rates of synthetic FePO (sub 4) .2H (sub 2) O at 4500 h). Typical effluent-flow rate was maintained at 0.10+ or -0.01 mL min (super -1) . The measured dissolution rate of FePO (sub 4) .2H (sub 2) O by DFO-B and Ox, R (sub DFO-Ox) (super Obs) , was compared to the sum of dissolution rates by DFO-B (R (sub DFO-B) ) or Ox (R (sub Ox) ), R (sub DFO-Ox) (super Sum) (R (sub DFO-Ox) (super Sum) =R (sub DFO-B) +R (sub Ox) ). Results were analyzed using the t student test. Obtained data values with p< or =0.05 ( (super I) ) and < or =0.01 ( (super II) ) were considered to differ statistically from control experiments. Dissolution rates by DFO-B (R (sub DFO-B) ) increased with [DFOB] (sub 0) , and no evidence of surface masking became apparent. By contrast, dissolution rates by Ox (R (sub Ox) ) varied with [Ox] (sub 0) and pH (sub 0) . The kinetics of dissolution by Ox was not explained by a first-order mineral dissolution behavior. Dissolution rates by DFO-B and Ox (R (sub DFO-Ox) (super Obs) ) surpassed R (sub DFO-B) or R (sub Ox) , and increased with proton activity. Reacting FePO (sub 4) .2H (sub 2) O with DFO-B and high amounts of Ox resulted in higher values for R (sub DFO-Ox) (super Obs) relative to R (sub DFO-B) . Observed (R (sub DFO-Ox) (super Obs) ) to calculated (R (sub DFO-Ox) (super Sum) =R (sub DFO-B) +R (sub Ox) ) ratio was found to be highest at [DFOB] (sub 0) =50mu M and [Ox] (sub 0) =49mu M. Increases in the proton activity favors the dissolution of FePO (sub 4) .2H (sub 2) O by DFO-B and Ox, explained because the sequestration of Fe(III) at the surface vicinity in the form of adsorbed Fe(III)-oxalate complexes. A direct comparison between the dissolution behavior of FePO (sub 4) .2H (sub 2) O by DFO-B and Ox against those for goethite (alpha -FeOOH) and Al goethite (AlFeOOH) was conducted. The dissolution behavior was found to be a function of the mineral structure. R (sub DFO-B) values for FePO (sub 4) .2H (sub 2) O by 22.5mu M DFO-B surpassed those for alpha -FeOOH or alpha -AlFeOOH by 20mu M DFO-B, namely, 37, and 11.6 and 3-5mu molkg (super -1) h (super -1) , respectively. R (sub Ox) values for FePO (sub 4) .2H (sub 2) O by 49mM Ox surpassed that for alpha -FeOOH by 70mu M Ox or alpha -AlFeOOH by 50mu M Ox, namely, i.e., 12, and 0.7 and 0.1mu molkg (super -1) h (super -1) . The latter results agree with the idea of the inhibition of Fe release in goethite because its sequestration in the form of adsorbed Fe(III) oxalate complexes. In contrast, a different scenario holds true for dissolution by 50mu M DFO-B and 49mu M Ox. The dissolution rates for FePO (sub 4) .2H (sub 2) O, alpha -FeOOH, and alpha -AlFeOOH correspond to 50, and 39-42 and 71-129mu molkg (super -1) h (super -1) , respectively. The high extent of iron release from Al goethite is best explained because high-energy surface sites formed after Al substitution in goethite.

Reconstructions of past climate from bogs commenced in the 19th Century through examination of visible peat stratigraphy, and later formed the basis for a postglacial climatic scheme widely used in Northwest Europe. Nevertheless, misconceptions as to how bogs grow led to a 50-year lacuna in peat-climate study, before the concept of 'cyclic regeneration' in bogs was refuted. In recent decades, research using proxy-climate indicators from bogs has burgeoned. A range of proxies for past hydrological change has been developed, as well as use of pollen, bog oaks and pines and other data to reconstruct past temperatures. Most of this proxy-climate research has been carried out in Northern Europe, but peat-based research in parts of Asia and North America has increased, particularly during the last decade, while research has also been conducted in Australia, New Zealand and South America. This paper reviews developments in proxy-climate reconstructions from peatlands; chronicles use of a range of palaeo-proxies such as visible peat stratigraphy, plant macrofossils, peat humification, testate amoebae and non-pollen palynomorphs; and explains the use of wiggle-match radiocarbon dating and relationship to climate shifts. It details other techniques being used increasingly, such as biomarkers, stable-isotopes, inorganic geochemistry and estimation of dust flux; and points to new proxies under development. Although explicit protocols have been developed recently for research on ombrotrophic mires, it must be recognised that not all proxies and techniques have universal applicability, owing to differences in species assemblages, mire formation, topographic controls, and geochemical characteristics.

We estimate that the mass of aerosols arriving at North American shores from overseas is comparable with the total mass of particulates emitted domestically. Curbing domestic emissions of particulates and precursor gases, therefore, is not sufficient to mitigate aerosol impacts in North America. The imported contribution is dominated by dust leaving Asia, not by combustion-generated particles. Thus, even a reduction of industrial emissions of the emerging economies of Asia could be overwhelmed by an increase of dust emissions due to changes in meteorological conditions and potential desertification.

The detection of close-in giant planets around other stars was the first clue that this pattern is not universal and that planets' orbits can change substantially after their formation. Here, we report another violation of the orbit-composition pattern: two planets orbiting the same star with orbital distances differing by only 10% and densities differing by a factor of 8. One planet is likely a rocky "super-Earth," whereas the other is more akin to Neptune. These planets are 20 times more closely spaced and have a larger density contrast than any adjacent pair of planets in the solar system.

Many aspects of how inhomogeneous radiative forcings influence precipitation remain unclear, however. Here we investigate regional precipitation responses to various forcings imposed in different latitude bands in a climate model. We find that several regions show strong, significant responses to most forcings, but that the magnitude and even the sign depends upon the forcing location and type. Aerosol and ozone forcings typically induce larger responses than equivalent carbon dioxide (CO sub(2)) forcing, and the influence of remote forcings often outweighs that of local forcings. Consistent with this, ozone and especially aerosols contribute greatly to precipitation changes over the Sahel and South and East Asia in historical simulations, and inclusion of aerosols greatly increases the agreement with observed trends in these areas, which cannot be attributed to either greenhouse gases or natural forcings. Estimates of precipitation responses derived from multiplying our Regional Precipitation Potentials (RPP; the response per unit forcing relationships) by historical forcings typically capture the actual response in full transient climate simulations fairly well, suggesting that these relationships may provide useful metrics. The strong sensitivity to aerosol and ozone forcing suggests that although some air quality improvements may unmask greenhouse gas-induced warming, they have large benefits for reducing regional disruption of the hydrologic cycle.

In response to IAU resolutions encouraging the extension of the ICRF to additional frequency bands, VLBI frames have been made at 24, 32, and 43 GHz. Meanwhile, the 8.4 GHz work has been greatly improved with the 2009 release of the ICRF-2. This paper discusses the motivations for extending the ICRF to these higher frequency radio bands. Results to date will be summarized including evidence that the high frequency frames are rapidly approaching the accuracy of the 8.4 GHz ICRF-2. We discuss current limiting errors and prospects for the future accuracy of radio reference frames. We note that comparison of multiple radio frames is characterizing the frequency dependent systematic noise floor from extended source morphology and core shift. Finally, given Gaia's potential for high accuracy optical astrometry, we have simulated the precision of a radio-optical frame tie to be ~10-15 mu as (1-[sigma], per component).

Development intensity zones, based on percent ISA, are defined for each urban area emanating outward from the urban core to nearby rural areas and are used to stratify land surface temperature. The stratification is further constrained by biome type and elevaton to ensure objective intercompansons between urban zones within an urban settlement and between settlements. Stratification based on ISA allows the definition of hierarchically ordered urban zones that are consistent across urban settlements and scales. For cities within the northeastern US temperate mixed forest biome, we found that settlement size, shape, and development intensity significantly influenced the amplitude of summer daytime UHI. Our study indicates that for cities of similar size, the ISA density distribution within the urban area and the shape of the urbanized area as measured by area to perimeter ratio are significant modulators of UHI magnitude. Our results indicate that remotely sensed satellite data provide a consistent characterization of the UHI magnitude as well as its major drivers across regional scales.

In some saline and alkaline lake systems, however, authigenic clay minerals, forming at or near the sediment water interface, are a major sedimentary component. Often these clays are rich in Mg, influencing the geochemical budget of lake waters, and are therefore expected to influence the properties of contemporaneous authigenic carbonate precipitates (which may also contain Mg). This paper documents evidence for a systematic feedback between clay mineral and carbonate authigenesis through multiple precessionally driven, m-scale sedimentary cycles in lacustrine oil-shale deposits of the Eocene Green River Formation from the Uinta Basin (NE Utah). In the studied section, authigenic, Mg-rich, trioctahedral smectite content varies cyclically between 9 and 39 wt.%. The highest concentrations occur in oil-shales and calcareous mudstones deposited during high lake level intervals that favored sedimentary condensation, lengthening the time available for clay diagenesis and reducing dilution by other siliciclastic phases. An inverse relation between dolomite percentage of carbonate and trioctahedral smectite abundance suggests the Mg uptake during clay authigenesis provides a first order control on carbonate mineralogy that better explains carbonate mineralogical trends than the possible alternative controls of (1) variable Mg/Ca ratios in lake water and (2) degree of microbial activity in sediments. We also observe that cyclical change in carbonate mineralogy, believed to be induced by clay authigenesis, also causes isotopic covariation between delta (super 13) C (sub PDB) and delta (super 18) O (sub PDB) of bulk sediments because of differences in the equilibrium fractionation factors of dolomite and calcite ( approximately 2 ppm and approximately 2.6%, respectively). This provides an alternative mechanism for the common pattern of isotopic covariation, which is typically attributed to the effect of simultaneous changes in water balance and biological activity on the carbon and oxygen isotopic composition of lake waters. These findings may help improve paleoenvironmental reconstructions based on lacustrine carbonate records by adding to the factors known to influence the mineralogical, compositional and stable isotopic signals recorded by lacustrine carbonates.

The recent finding of significant levels of perchlorate (ClO (super -) (sub 4) ) in regolith sampled from the Phoenix landing site raises the question of its potential biotoxicity to putative indigenous martian life, microbial forward contaminants from Earth, or future human visitors. To address this issue, an analogue regolith was constructed based on regolith chemistry data from the Phoenix landing site. A Mars Aqueous Regolith Extract (MARE) was prepared from the Phoenix analogue regolith and analyzed by ion chromatography. The MARE contained (mg/L) the cations Na (super +) (1411 + or - 181), Mg (super 2+) (1051 + or - 160), Ca (super 2+) (832 + or - 125), and K (super +) (261 + or - 29), and the anions SO (super 2-) (sub 4) , (5911 + or - 993), ClO (super -) (sub 4) (5316 + or - 1767), Cl (super -) (171 + or - 52) and F (super -) (2.0 + or - 0.4). Nitrogen-containing species NO (super -) (sub 3) (773 + or - 113) and were also present as a result of regolith preparation procedures, but their relevance to Mars is at present unknown. The MARE was tested for potential toxic effects on two model spacecraft contaminants, the spore-forming bacteria Bacillus subtilis strain 168 and Bacillus pumilus strain SAFR-032. In B. subtilis, spore germination and initial vegetative growth (up to approximately 5 h) was not inhibited in a rich complex medium prepared with the MARE, but growth after 5 h was significantly suppressed in medium prepared using the MARE. Both B. subtilis and B. pumilus exhibited significantly higher rates of spore germination and growth in the MARE vs. DW with no additions (likely due to endogenous spore nutrients), but germination and growth was further stimulated by addition of glucose and a combination of buffered inorganic salts (K (sub 2) HPO (sub 4) , KH (sub 2) PO (sub 4) ,(NH (sub 4) ) (sub 2) SO (sub 4) , and MgSO (sub 4) ). The data indicate that the aqueous environment in the regolith from the Phoenix landing site containing high levels of perchlorate does not pose a significant barrier to growth of putative forward contaminants such as B. subtilis and B. pumilus under Earth laboratory conditions.

X., Gay, J., Guillot, T., Jacob, C. [2011]. Astron. Astrophys. 531, A104). This exciting result can provide constraints on gross jovian properties and warrants a more in-depth theoretical study of the seismic structure of Jupiter. With current instrumentation, such as the SYMPA instrument (Schmider, F. X. [2007]. Astron. Astrophys. 474, 1073-1080) used for the Gaulme et al. (Gaulme, P., Schmider, F. X., Gay, J., Guillot, T., Jacob, C. [2011]. Astron. Astrophys. 531, A104) analysis, we assume that, at minimum, a set of global frequencies extending up to angular degree l=25 could be observed. In order to identify which modes would best constraining models of Jupiter's interior and thus help motivate the next generation of observations, we explore the sensitivity of derived parameters to this mode set. Three different models of the jovian interior are computed and the theoretical pulsation spectrum from these models for l=25 is obtained. We compute sensitivity kernels and perform linear inversions to infer details of the expected discontinuities in the profiles in the jovian interior. We find that the amplitude of the sound-speed jump of a few percent in the inner/outer envelope boundary seen in two of the applied models should be reasonably inferred with these particular modes. Near the core boundary where models predict large density discontinuities, the location of such features can be accurately measured, while their amplitudes have more uncertainty. These results suggest that this mode set would be sufficient to infer the radial location and strength of expected discontinuities in Jupiter's interior, and place strong constraints on the core size and mass. We encourage new observations to detect these jovian oscillations.

We also reviewed the thermal and aqueous alteration history of these meteorites and searched for trends between spectral parameters and temperature histories in order to uncover spectral-compositional relationships. Aqueous alteration results in the production of phyllosilicates from anhydrous silicate precursors - largely serpentine group phyllosilicates, and increasing amounts of saponite group phyllosilicates with increasing aqueous alteration. Thermal metamorphism results in dehydration of these phyllosilicates and production of abundant amorphous material except at the highest temperatures ( approximately 900 degrees C), as well as alteration of carbonaceous components. ATCCs are a spectrally diverse group in almost all respects. Spectral slopes, as measured by the ratio of reflectance at 2.4 mu m to the local peak or inflection in the 0.5-0.8 mu m region and 2.4/1.5 mu m ratios range from 0.78 to 1.48, and 0.93 to 1.24, respectively (blue-sloped spectra have ratio values of <1). ATCC powder spectra (<75, <100, or <125 mu m) are generally dark, with maximum reflectance at the local peak or inflection in the 0.5-0.8 mu m region, or maximum reflectance at any wavelength ranging from 2.6% to 8.9%, and 3.5% to 10.3%, respectively. All ATCC spectra exhibit an absorption feature in the approximately 0.8-1.3 mu m region, with band depths ranging from approximately 1% to 8%. This feature is diverse in terms of number of apparent absorption bands. The presence of mixed valence Fe (super 2+) -Fe (super 3+) phyllosilicates, as evidenced by an absorption band near 0.7 mu m with a depth of up to 5%, and Mg-bearing phyllosilicates, as evidenced by an MgOH combination band in the 2.3-2.4 mu m region, are seen in many of the least thermally metamorphosed ATCC spectra. The depth of the 0.7 mu m band generally decreases with increasing temperature. Olivine-associated absorption bands in the 0.8-1.3 mu m region seem to be more prevalent in the more metamorphosed ATCC spectra. However clearly-resolvable olivine absorption bands are not present in ATCC spectra, suggesting that thermal metamorphism did not lead to the production of widespread crystalline Fe (super 2+) -bearing olivine. The reddest ATCC powder spectra are generally the darkest, and C content is correlated with decreasing overall reflectance and weakly correlated with spectral slope. When the degree of thermal metamorphism was compared to various spectral measures of slope, band depth, and overall reflectance, no strong correlations emerged. However, it does appear that the most thermally metamorphosed ATCCs have generally flatter spectral slopes. ATCC chip spectra are brighter and less red-sloped than powder spectra, but band depths are generally comparable. Laboratory-heated CIs and CMs generally exhibit the same types of spectral changes seen in naturally thermally metamorphosed ATCCs. For laboratory-heated CM and CI chondrites, and ATCCs for which temperature estimates are available, reflectance generally decreases with increasing temperature to approximately 500 degrees C, and then increases to higher temperatures. Silicate absorption band depths are generally least for temperatures of approximately 600-800 degrees C. Below this temperature interval, ATCC spectra show more phyllosilicate-like absorption bands. ATCC spectra generally become flatter with increasing temperature above approximately 400 degrees C. Temperatures in excess of those experienced by the ATCCs ( approximately 900 degrees C) are required for the appearance of well-resolved olivine absorption bands.

As a group, our CO powder spectra have some similarities and differences. COs have experienced varying degree of thermal metamorphism, with petrologic subgrades ranging from approximately CO3.0 to approximately CO3.8. Their reflectance spectra are characterized by a ubiquitous absorption feature in the 1 ?m region, and a nearly ubiquitous feature in the 2 mu m region that appears in CO >3.1 spectra. The 1 mu m region feature is attributable to abundant Fe-bearing amorphous phases (and Fe-poor olivine) in the lower petrologic subtypes, which gradually transforms to more abundant and Fe-rich olivine with increasing metamorphism. The increase in depth and decrease in wavelength position of this feature are consistent with this transformation. All but the least-altered COs also exhibit an absorption feature in the 2 mu m region whose depth also generally increases with increasing metamorphic grade, resulting in increasingly blue-sloped spectra and larger band area ratios. The wavelength position and change in depth of this feature (ranging from 0% to 12.2%) is consistent with increasing Fe (super 2+) in spinel, which is present in calcium-aluminum and ameboid olivine inclusions. Reflectance of a local reflectance maximum near 0.8 mu m increases with increasing thermal metamorphism and this is likely due to the loss and aggregation of carbonaceous phases. The increasing reflectance is negatively correlated with various measures of spectral slope (i.e., brighter = bluer), and while this cannot be uniquely attributed to any one cause, it is consistent with increasing spinel Fe (super 2+) content and decreasing carbonaceous material abundance or aggregation. With decreasing grain size, CO spectra normally become brighter and more red-sloped. The 0.6/0.5 mu m ratios of CO falls are consistently higher than CO finds, suggesting that terrestrial weathering has affected the visible wavelength region spectral properties of finds. Unmetamorphosed CO spectra may be difficult to distinguish from the least altered CM chondrites. However above petrologic grade approximately 3.1, COs can be uniquely discriminated from CI, CM, metamorphosed CI and CM, and CR chondrites, by the presence of both olivine and spinel absorption bands. Some K-class asteroids exhibit olivine and spinel absorption bands, consistent with CO chondrites, although modeled olivine:spinel ratios are generally lower in these asteroids than in CO chondrites.

A densely pitted crater-related unit has been identified in images of 204 craters from the Mars Reconnaissance Orbiter. This sample of craters are nearly equally distributed between the two hemispheres, spanning from 53 degrees S to 62 degrees N latitude. They range in diameter from approximately 1 to 150 km, and are found at elevations between -5.5 to +5.2 km relative to the martian datum. The pits are polygonal to quasi-circular depressions that often occur in dense clusters and range in size from ?10 m to as large as 3 km. Pit sizes scale with both the host crater's diameter and the host deposit size. These pits have subtle raised rims, and unlike primary and secondary impact craters, they lack well-defined ejecta deposits and overlapping stratigraphic relationships. They also lack any sign of any preferential alignment expected of volcanic or tectonic collapse features. Morphologic and stratigraphic evidence in support of an impact origin includes the observation that pitted materials primarily occur as ponded and flow-like deposits on crater floors, behind terraces, and infilling the lowest local topographic depressions atop the ejecta blanket-similar to the distribution of impact melt-bearing bodies on the Moon. Based on the observations and comparisons to terrestrial and lunar analogs, we conclude that the pit-bearing materials are impactite deposits. The presence of these deposits in older craters, where preserved, suggests that they have formed on Mars throughout most of its geologic history; thus, understanding their origin may help to constrain the hydrological and climate history of Mars.

Two essential properties of OM-rich shales, the total specific surface area (TSSA) and cation exchange capacity (CEC), are primarily controlled by the rock's clay mineral content (i.e. the type and quantity). This paper presents the limitations of two commonly used methods of measuring bulk-rock TSSA and CEC, ethylene glycol monoethyl ether (EGME) retention and visible light spectrometry of Co(III)-hexamine, in OM-rich rocks. The limitations were investigated using a suite of OM-rich shales and mudstones that vary in origin, age, clay mineral content, and thermal maturity. Ethylene glycol monoethyl ether reacted strongly with and was retained by natural OM, producing excess TSSA if calculated using commonly applied adsorption coefficients. Although the intensity of the reaction seems to depend on thermal maturity, OM in all the samples analyzed reacted with EGME to an extent that made TSSA values unreliable; therefore, EGME is not recommended for TSSA measurements on samples containing >3% OM. Some evidence indicated that drying at > or =200 degrees C may influence bulk-rock CEC values by altering OM in early mature rocks. In light of this evidence, drying at 110 degrees C is recommended as a more suitable pre-treatment for CEC measurements in OM-rich shales. When using visible light spectrometry for CEC determination, leachable sample components contributed to the absorbance of the measured wavelength (470 nm), decreasing the calculated bulk rock CEC value. A test of sample-derived excess absorbance with zero-absorbance solutions (i.e. NaCl) and the introduction of corrections to the CEC calculation are recommended.

Measurements of OH and HO sub(2) from the Penn State ATHOS instrument are compared to model predictions. Forty percent of OH measurements below 2 km are at the limit of detection during the spring phase (ARCTAS-A). While the median observed-to-calculated ratio is near one, both the scatter of observations and the model uncertainty for OH are at the magnitude of ambient values. During the summer phase (ARCTAS-B), model predictions of OH are biased low relative to observations and demonstrate a high sensitivity to the level of uncertainty in NO observations. Predictions of HO sub(2) using observed CH sub(2)O and H sub(2)O sub(2) as model constraints are up to a factor of two larger than observed. A temperature-dependent terminal loss rate of HO sub(2) to aerosol recently proposed in the literature is shown to be insufficient to reconcile these differences. A comparison of ARCTAS-A to the high latitude springtime portion of the 2000 TOPSE campaign (Tropospheric Ozone Production about the Spring Equinox) shows similar meteorological and chemical environments with the exception of peroxides; observations of H sub(2)O sub(2) during ARCTAS-A were 2.5 to 3 times larger than those during TOPSE. The cause of this difference in peroxides remains unresolved and has important implications for the Arctic HO sub(x) budget. Unconstrained model predictions for both phases indicate photochemistry alone is unable to simultaneously sustain observed levels of CH sub(2)O and H sub(2)O sub(2); however when the model is constrained with observed CH sub(2)O, H sub(2)O sub(2) predictions from a range of rainout parameterizations bracket its observations. A mechanism suitable to explain observed concentrations of CH sub(2)O is uncertain. Free tropospheric observations of acetaldehyde (CH sub(3)CHO) are 2-3 times larger than its predictions, though constraint of the model to those observations is sufficient to account for less than half of the deficit in predicted CH sub(2)O. The box model calculates gross O sub(3) formation during spring to maximize from 1-4 km at 0.8 ppbv d super(-1), in agreement with estimates from TOPSE, and a gross production of 2-4 ppbv d super(-1) in the boundary layer and upper troposphere during summer. Use of the lower observed levels of HO sub(2) in place of model predictions decreases the gross production by 25-50%. Net O sub(3) production is near zero throughout the ARCTAS-A troposphere, and is 1-2 ppbv in the boundary layer and upper altitudes during ARCTAS-B.

Methods to predict specific health effects from exposure to a mixture of air pollutants are not well developed. Herein, air monitoring data from the ISS are used to demonstrate a new method to estimate a threshold for possible health effects from exposure to mixtures. Methods: An empirical, additive approach was developed to transform monthly air pollutant data, which had been obtained primarily by gas chromatography-mass spectrometry from samples of ISS air, to threshold (T) values for 16 adverse health effect groups. Spacecraft maximum allowable concentrations (SMACs), available for most spacecraft air pollutants, were used to form target-organ/effect groups, from which group T values were estimated. If T>1 for a group, then there is an unacceptable risk of the toxic effect. Results: Samples of air taken from the ISS in 2010 revealed that all 1 6 toxicological groups were within safe limits. HighestT values were as follows: mucosal irritants (0.53 plus or minus 0.44), headache (0.52 plus or minus 0.06), central nervous system depression (0.25 plus or minus 0.06), and cardiac sensitization (0.13 plus or minus 0.04). Discussion: The additive model is supported by limited inhalation data on rats in the literature. Our predictions of no adverse effect on crew health are useful as part of NASA's Lifetime Surveillance of Astronaut Health (LSAH). If one of the 16 levels had exceeded T=1, then standard surveillance could be supplemented to address this potential health risk.

This new GFMS is quantitatively evaluated in terms of flood event detection during the TRMM era (1998-2010) using a global retrospective simulation (3-hourly and 1/8 degree spatial resolution) with the TMPA 3B42V6 rainfall. Four methods were explored to define flood thresholds from the model results, including three percentile-based statistical methods and a Log Pearson type-III flood frequency curve method. The evaluation showed the GFMS detection performance improves [increasing probability of detection (POD)] with longer flood durations and larger affected areas. The impact of dams was detected in the validation statistics, with the presence of dams tending to result in more false alarms and greater false-alarm duration. The GFMS validation statistics for flood durations >3 days and for areas without dams vary across the four methods, but center around a POD of ~0.70 and a false-alarm rate (FAR) of ~0.65. The generally positive results indicate the value of this approach for monitoring and researching floods on a global scale, but also indicate limitations and directions for improvement of such approaches. These directions include improving the rainfall estimates, utilizing higher resolution in the runoff-routing model, taking into account the presence of dams, and improving the method for flood identification.

We retrospectively reviewed the medical records of patients treated at our institution between October 2006 and September 2009 and identified 161 patients who had undergone CT-guided TNB or FNA. We conducted CT-guided TNB or FNA for the patients if bronchoscopy failed to provide proper diagnosis or if their thoracic lesions were not appropriate targets for bronchoscopy. Twenty-three patients were diagnosed with pulmonary infectious diseases, of whom 17 were diagnosed by CT-guided TNB or FNA; sensitivity was therefore 73.9 % (17/23). The diagnostic rate for Aspergillus infection was especially high (75 %). CT-guided TNB and FNA proved to be effective as alternative methods if bronchoscopy failed to diagnose pulmonary infectious diseases, with acceptable complication rates.[PUBLICATION ABSTRACT] JF - Japanese Journal of Radiology AU - Uruga, Hironori AU - Takaya, Hisashi AU - Hanada, Shigeo AU - Beika, Yuka AU - Miyamoto, Atsushi AU - Morokawa, Nasa AU - Kurosaki, Atsuko AU - Fujii, Takeshi AU - Kishi, Kazuma Y1 - 2012/08// PY - 2012 DA - Aug 2012 SP - 589 EP - 93 CY - Tokyo PB - Springer Science & Business Media VL - 30 IS - 7 SN - 18671071 KW - Medical Sciences--Oncology KW - Pulmonary Aspergillosis -- radiography KW - Biopsy, Fine-Needle KW - Diagnosis, Differential KW - Humans KW - Lung Diseases -- pathology KW - Retrospective Studies KW - Aged KW - Aged, 80 & over KW - Pulmonary Aspergillosis -- pathology KW - Bronchoscopy KW - Adult KW - Middle Aged KW - Sensitivity & Specificity KW - Female KW - Male KW - Tomography, X-Ray Computed -- methods KW - Lung Diseases -- radiography KW - Lung Diseases -- microbiology KW - Radiography, Interventional KW - Biopsy, Needle -- methods UR - http://libproxy.lib.unc.edu/login?url=http://search.proquest.com/docview/1037267765?accountid=14244 L2 - http://vb3lk7eb4t.search.serialssolutions.com/?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQ%3Ahealthcompleteshell&rft_val_fmt=info:ofi/fmt:kev:mtx:journal&rft.genre=article&rft.jtitle=Japanese+Journal+of+Radiology&rft.atitle=Diagnostic+efficacy+of+CT-guided+transthoracic+needle+biopsy+and+fine+needle+aspiration+in+cases+of+pulmonary+infectious+disease&rft.au=Uruga%2C+Hironori%3BTakaya%2C+Hisashi%3BHanada%2C+Shigeo%3BBeika%2C+Yuka%3BMiyamoto%2C+Atsushi%3BMorokawa%2C+Nasa%3BKurosaki%2C+Atsuko%3BFujii%2C+Takeshi%3BKishi%2C+Kazuma&rft.aulast=Uruga&rft.aufirst=Hironori&rft.date=2012-08-01&rft.volume=30&rft.issue=7&rft.spage=589&rft.isbn=&rft.btitle=&rft.title=Japanese+Journal+of+Radiology&rft.issn=18671071&rft_id=info:doi/10.1007%2Fs11604-012-0094-3 LA - English DB - ProQuest Central N1 - Copyright - Japan Radiological Society 2012 N1 - Last updated - 2014-09-06 DO - http://dx.doi.org/10.1007/s11604-012-0094-3 ER - TY - JOUR T1 - Nonmyeloablative conditioning generates autoantigen-encoding bone marrow that prevents and cures an experimental autoimmune disease. AN - 1030503649; 22694476 AB - Autoimmune diseases result from chronic targeted immune responses that lead to tissue pathology and disease. The potential of autologous hematopoietic stem cells transplantation as a treatment for autoimmunity is currently being trialled but disease relapse is an issue. We have previously shown in a mouse model of experimental autoimmune encephalomyelitis (EAE) that the transplantation of bone marrow (BM) transduced to encode the autoantigen myelin oligodendrocyte glycoprotein (MOG) can prevent disease induction. However these studies were performed using lethal irradiation to generate BM chimeras and a critical factor for translation to humans would be the ability to utilize low toxic preconditioning regimes. In this study, treosulfan was used as a nonmyeloablative agent to generate BM chimeras encoding MOG and assessed in models of EAE induction and reversal. We find that treosulfan conditioning can promote a low degree of chimerism that is sufficient to promote antigen specific tolerance and protect mice from EAE. When incorporated into a curative protocol for treating mice with established EAE, nonmyeloablative conditioning and low chimerism was equally efficient in maintaining disease resistance. These studies further underpin the potential and feasibility of utilizing a gene therapy approach to treat autoimmune disease. © Copyright 2012 The American Society of Transplantation and the American Society of Transplant Surgeons.

The sudden brightening persisted as a plateau of Fe XIX intensity that endured more than 11 minutes. The Fe XIX emission at the rise and during the life of the plateau showed no evidence of significant bulk velocity flows, and hence cannot be attributed to chromospheric evaporation. However, the line width showed a significant broadening at the rise of the plateau, corresponding to nonthermal velocities of at least 89 km s super(-1) due to reconnection outflows or turbulence. During the plateau He I, O V, and Si XII brightened at successively later times starting about 3.5 minutes after Fe XIX, which suggests that these brightenings were produced by thermal conduction from the plasma that produced the Fe XIX line emission; however, we cannot rule out the possibility that they were produced by a weak beam of nonthermal particles. We interpret an observed shortening of the O V wavelength for about 1.5 minutes toward the middle of the plateau to indicate new upward motions driven by the flare, as occurs during gentle chromospheric evaporation; relative to a quiescent interval shortly before the flare, the O V upward velocity was around -10 km s super(-1).

We report the results of confocal Raman imaging spectroscopy on 11 martian meteorites, spanning about 4.2 billion years of martian history. Ten of the meteorites contain abiotic macromolecular carbon (MMC) phases detected in association with small oxide grains included within high-temperature minerals. Polycyclic aromatic hydrocarbons were detected along with MMC phases in Dar al Gani 476. The association of organic carbon within magmatic minerals indicates that martian magmas favored precipitation of reduced carbon species during crystallization. The ubiquitous distribution of abiotic organic carbon in martian igneous rocks is important for understanding the martian carbon cycle and has implications for future missions to detect possible past martian life.

Variations at these positions indicate changes in local conditions and materials sampled. The major findings are: (1) PAH erosion and destruction are important from the BB out to about 5'. (2) The ionized PAH fraction, inferred from the 11.0 mu m PAH band, increases from the BB out to 6.'5. This counterintuitive behavior is linked to PAH dehydrogenation. (3) The "11.2" mu m PAH band profile shifts from class A (sub 11.2) to A(B) (sub 11.2) between 9' and 10', indicating these lines-of-sight probe a different environment, likely shielded molecular cloud material. (4) The different spatial behavior of the PAH bands and the 10-15 mu m plateau supports the view that the plateau originates in a separate carrier. (5) The fullerene/PAH band strength ratio decreases out to about 7', increases between 9' and 10' and drops at 12'. The first region is where PAHs are dehydrogenated and eroded whereas the second, shielded zone, is where the "11.2" mu m profile shifts and PAH erosion is unlikely. This suggests fullerenes are intimately mixed with PAHs in shielded regions. Taken together, the observations suggest three different regimes are sampled: (1) the H II region-photodissociation region (PDR) interface directly southeast of the BB, (2) shielded molecular cloud material farther out, and (3) the H II region-PDR interface seen limb brightened at the outermost position.

The irradiance differences are calculated for various temporal and spatial scales, monthly gridded, monthly zonal, monthly global, and annual global. Using the irradiance differences, the uncertainty of surface irradiances is estimated. The uncertainty (1sigma ) of the annual global surface downward longwave and shortwave is, respectively, 7 W m (super -2) (out of 345 W m (super -2) ) and 4 W m (super -2) (out of 192 W m (super -2) ), after known bias errors are removed. Similarly, the uncertainty of the annual global surface upward longwave and shortwave is, respectively, 3 W m (super -2) (out of 398 W m (super -2) ) and 3 W m (super -2) (out of 23 W m (super -2) ). The uncertainty is for modeled irradiances computed using cloud properties derived from imagers on a sun-synchronous orbit that covers the globe every day (e.g., moderate-resolution imaging spectrometer) or modeled irradiances computed for nadir view only active sensors on a sun-synchronous orbit such as Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation and CloudSat. If we assume that longwave and shortwave uncertainties are independent of each other, but up- and downward components are correlated with each other, the uncertainty in global annual mean net surface irradiance is 12 W m (super -2) . One-sigma uncertainty bounds of the satellite-based net surface irradiance are 106 W m (super -2) and 130 W m (super -2) .

N. Loeb and B. Soden convened this session including 10 presentations by B. Stevens, B. Wielicki, G. Stephens, A. Clement, K. Sassen, D. Hartmann, T. Andrews, A. Del Genio, H. Barker, and M. Sugi addressing critical aspects of the role of clouds in modulating Earth energy flows. Presentation topics covered a diverse range of areas from cloud microphysics and dynamics, cloud radiative transfer, and the role of clouds in large-scale atmospheric circulations patterns in both observations and atmospheric models. The presentations and discussions, summarized below, are organized around several key questions raised during the session. (1) What is the best way to evaluate clouds in climate models? (2) How well do models need to represent clouds to be acceptable for making climate predictions? (3) What are the largest uncertainties in clouds? (4) How can these uncertainties be reduced? (5) What new observations are needed to address these problems? Answers to these critical questions are the topics of ongoing research and will guide the future direction of this area of research.

Large-scale TOA radiation changes during the past decade are observed to be within 0.5 Wm (super -2) per decade based upon comparisons between Clouds and the Earth's Radiant Energy System (CERES) instruments aboard Terra and Aqua and other instruments. Tropical variations in emitted outgoing longwave (LW) radiation are found to closely track changes in the El Nino-Southern Oscillation (ENSO). During positive ENSO phase (El Nino), outgoing LW radiation increases, and decreases during the negative ENSO phase (La Nina). The coldest year during the last decade occurred in 2008, during which strong La Nina conditions persisted throughout most of the year. Atmospheric Infrared Sounder (AIRS) observations show that the lower temperatures extended throughout much of the troposphere for several months, resulting in a reduction in outgoing LW radiation and an increase in net incoming radiation. At the global scale, outgoing LW flux anomalies are partially compensated for by decreases in midlatitude cloud fraction and cloud height, as observed by Moderate Resolution Imaging Spectrometer and Multi-angle Imaging SpectroRadiometer, respectively. CERES data show that clouds have a net radiative warming influence during La Nina conditions and a net cooling influence during El Nino, but the magnitude of the anomalies varies greatly from one ENSO event to another. Regional cloud-radiation variations among several Terra and A-Train instruments show consistent patterns and exhibit marked fluctuations at monthly timescales in response to tropical atmosphere-ocean dynamical processes associated with ENSO and Madden-Julian Oscillation.

A scene construction algorithm, developed for the EarthCARE mission, was applied to CloudSat, CALIPSO and MODIS satellite data thus producing 3D cloudy atmospheres measuring 61 km wide by 14,000 km long at 1 km grid-spacing. Broadband solar fluxes and radiances were then computed by a Monte Carlo photon transfer model run in both full 3D and 1D independent column approximation modes. Results were averaged into 1,303 (50 km) (super 2) domains. For domains with total cloud fractions A (sub c ) 0.7 and characterized by small bias yet large random errors. Regardless of A (sub c ) , differences between 3D and 1D transfer rarely exceed + or -30 W m (super -2) for net TOA and surface fluxes and + or -10 W m (super -2) for atmospheric absorption. Horizontal fluxes through domain sides depend on A (sub c ) with approximately 20% of cases exceeding + or -30 W m (super -2) ; the largest values occur for A (sub c ) > 0.7. Conversely, heating rate differences rarely exceed + or -20%. As a cursory test of TOA radiative closure, fluxes produced by the 3D model were averaged up to (20 km) (super 2) and compared to values measured by CERES. While relatively little attention was paid to optical properties of ice crystals and surfaces, and aerosols were neglected entirely, approximately 30% of the differences between 3D model estimates and measurements fall within + or -10 W m (super -2) ; this is the target agreement set for EarthCARE. This, coupled with the aforementioned comparison between 3D and 1D transfer, leads to the recommendation that EarthCARE employ a 3D transport model when attempting TOA radiative closure.

To monitor the spatially and temporally varying global atmospheric aerosol load, satellite remote sensing is required. Despite major advances in observing aerosol amount, type, and distribution from space, satellite data alone cannot provide enough quantitative detail, especially about aerosol microphysical properties, to effect the required improvement in estimates of DARF and the anthropogenic component of DARF. However, the combination of space-based and targeted suborbital measurements, when used to constrain climate models, represents an achievable next step likely to provide the needed advancement.

Cumulus parameterization development has focused primarily on the second phase until recently. Consequently, many parameterizations are not sufficiently sensitive to variations in tropospheric humidity. This shortcoming may affect global climate model simulations of climate sensitivity to external forcings, the continental diurnal cycle of clouds and precipitation, and intraseasonal precipitation variability. The lack of sensitivity can be traced in part to underestimated entrainment of environmental air into rising convective clouds and insufficient evaporation of rain into the environment. As a result, the parameterizations produce deep convection too easily while stabilizing the environment too quickly to allow the effects of convective mesoscale organization to occur. Recent versions of some models have increased their sensitivity to tropospheric humidity and improved some aspects of their variability, but a parameterization of mesoscale organization is still absent from most models. Evidence about the effect of these uncertainties on climate change projections suggests that climate modelers should make improved simulation of high and convective clouds as high a priority as better representations of low clouds.

Interannual variability in radiative forcing and snowmelt rates AN - 1566844815; 20688596 AB - Here we present the radiative and snowmelt impacts of dust deposition to snow cover using a 6-year energy balance record (2005-2010) at alpine and subalpine micrometeorological towers in the Senator Beck Basin Study Area (SBBSA) in southwestern Colorado, USA. These results follow from the measurements described in part I. We simulate the evolution of snow water equivalent at each station under scenarios of observed and dust-free conditions, and +2 degree C and +4 degree C melt-season temperature perturbations to these scenarios. Over the 6 years of record, daily mean dust radiative forcing ranged from 0 to 214 W m super(-2), with hourly peaks up to 409 W m super(-2). Mean springtime dust radiative forcings across the period ranged from 31 to 49 W m super(-2) at the alpine site and 45 to 75 W m super(-2) at the subalpine site, in turn shortening snow cover duration by 21 to 51 days. The dust-advanced loss of snow cover (days) is linearly related to total dust concentration at the end of snow cover, despite temporal variability in dust exposure and solar irradiance. Under clean snow conditions, the temperature increases shorten snow cover by 5-18 days, whereas in the presence of dust they only shorten snow duration by 0-6 days. Dust radiative forcing also causes faster and earlier peak snowmelt outflow with daily mean snowpack outflow doubling under the heaviest dust conditions. On average, snow cover at the towers is lost 2.5 days after peak outflow in dusty conditions, and 1-2 weeks after peak outflow in clean conditions. Key Points * Dust in snow in the Colorado River Basin absorbs extra 31 to 75 W m-2 in spring * This dust radiative forcing shortens snow cover duration by 21 to 51 days * Melt season temperature increases of 2 to 4 deg C shorten snow cover 5-18 days JF - Water Resources Research AU - Skiles, SMcKenzie AU - Painter, Thomas H AU - Deems, Jeffrey S AU - Bryant, Ann C AU - Landry, Christopher C AD - Department of Geography, University of California,Los Angeles, California,USA., thomas.painter@jpl.nasa.gov Y1 - 2012/07// PY - 2012 DA - Jul 2012 SP - [np] PB - American Geophysical Union, 2000 Florida Ave., N.W.

A 6 year record of energy balance, radiation, and dust concentrations AN - 1566837536; 20688597 AB - Dust in snow accelerates snowmelt through its direct reduction of snow albedo and its further indirect reduction of albedo by accelerating the growth of snow grains. Since the westward expansion of the United States that began in the mid-19th century, the mountain snow cover of the Colorado River Basin has been subject to five-fold greater dust loading, largely from the Colorado Plateau and Great Basin. Radiative forcing of snowmelt by dust is not captured by conventional micrometeorological measurements, and must be monitored by a more comprehensive suite of radiation instruments. Here we present a 6 year record of energy balance and detailed radiation measurements in the Senator Beck Basin Study Area, San Juan Mountains, Colorado, USA. Data include broadband irradiance, filtered irradiance, broadband reflected flux, filtered reflected flux, broadband and visible albedo, longwave irradiance, wind speed, relative humidity, and air temperatures. The gradient of the snow surface is monitored weekly and used to correct albedo measurements for geometric effects. The snow is sampled weekly for dust concentrations in plots immediately adjacent to each tower over the melt season. Broadband albedo in the last weeks of snow cover ranged from 0.33 to 0.55 across the 6 years and two sites. Total end of year dust concentration in the top 3 cm of the snow column ranged from 0.23 mg g super(-1) to 4.16 mg g super(-1). These measurements enable monitoring and modeling of dust and climate-driven snowmelt forcings in the Upper Colorado River Basin.

However, most focus has been on validation of inundation extent, with little attention on the spatial variations of water elevation and slope. The availability of high resolution Interferometric Synthetic Aperture Radar (InSAR) imagery offers unprecedented opportunity for quantitative validation of surface water heights and slopes derived from 2D hydrodynamic models. In this study, the LISFLOOD-ACC hydrodynamic model is applied to the central Atchafalaya Basin Floodway System, Louisiana, during high flows typical of spring floods in the Mississippi Delta region, for the purpose of demonstrating the utility of InSAR in 2-D floodplain model calibration. Two schemes calibrating Manning's roughness in channels and floodplains are compared. First, the model is calibrated in terms of water elevations at a single in situ gage during a 62-d simulation period from 1 April 2008 to 1 June 2008. Second, the model is calibrated in terms of water elevation changes calculated from ALOS PALSAR 2D imagery acquired on 16 April 2008 and 1 June 2009, an interval of 46 d. The best-fit model shows that the mean absolute error is 5.7 cm/46 d for InSAR water level calibration. Daily storage changes within the 230-km super(2) model area are also calculated to be on the order of 107 m super(3) d super(-1) during high water of the modeled period.

The rationale behind the development was that the current outcome measure is subjective and dependent upon how much the clinical psychologist knows about subject behaviors during the study to rate them accurately. Methods: The behaviorallv anchored rating scales (BARS) were developed through the use of the critical incident technique, along with traditional BARS development procedures, and the use of focus groups. Results: Use of these methodologies yielded 86 usable critical incidents, which were used as anchors for the scales. Discussion: Further research will be necessary to determine whether or not associations exist between data from the BARS and psychological screening data.

This study presents a method for risk assessment and control of landslides in regions where groundwater levels can be affected by reservoir water levels. The method is illustrated with a case study of the Hongzhuang reservoir in Yanan city, northern Shaanxi province, China. A groundwater numerical model was developed using MODFLOW and the groundwater flow fields were calculated for different reservoir water levels. Safety factors were then obtained and the slope stability was analyzed. Moreover, a probabilistic slope analysis was performed by Monte-Carlo simulation to evaluate the reliability of slope stability and the probability of slope failure. Finally, a reasonable reservoir water level was determined according to the acceptable risk level, and a comprehensive risk mitigation method was proposed considering water level control, relocation, and drainage measures.

Irrigation thus started in 1968. Perched water table was significantly raised and resulted in many loess flow failures in the past 30 years. This type of landslide was often featured by long runout distance, high speed and recurrence. Laboratory tests along ICU and CSD stress paths were performed. It is shown that the loess has a strong strain-softening behavior and instability can occur in drained condition before undrained liquefaction. The failure mechanism of loess flow can be interpreted as the following process: with increasing perched water table, collapse in loess was first triggered in drained condition and led to undrained loading to adjacent soil in the lower saturated part of the loess platform. Under gravity loading applied by upper dry loess, undrained flow failure mobilized, eventually.

Recent advancements in the availability and accessibility of remote sensing data, including topography, land cover and precipitation products, allow landslide hazard assessment to be considered at larger spatial scales. A theoretical framework for a landslide forecasting system was prototyped in this study using several remotely sensed and surface parameters. The applied physical model SLope-Infiltration-Distributed Equilibrium (SLIDE) takes into account some simplified hypotheses on water infiltration and defines a direct relation between factor of safety and the rainfall depth on an infinite slope. This prototype model is applied to a case study in Honduras during Hurricane Mitch in 1998. Two study areas were selected where a high density of shallow landslides occurred, covering approximately 1,200 km (super 2) . The results were quantitatively evaluated using landslide inventory data compiled by the United States Geological Survey (USGS) following Hurricane Mitch's landfall. The agreement between the SLIDE modeling results and landslide observations demonstrates good predictive skill and suggests that this framework could serve as a potential tool for the future early landslide warning systems. Results show that within the two study areas, the values of rates of successful estimation of slope failure locations reached as high as 78 and 75%, while the error indices were 35 and 49%. Despite positive model performance, the SLIDE model is limited by several assumptions including using general parameter calibration rather than in situ tests and neglecting geologic information. Advantages and limitations of this physically based model are discussed with respect to future applications of landslide assessment and prediction over large scales.

A prototype global satellite-based landslide hazard algorithm has been developed to identify areas that may experience landslide activity. This system combines a calculation of static landslide susceptibility with satellite-derived rainfall estimates and uses a threshold approach to generate a set of 'nowcasts' that classify potentially hazardous areas. A recent evaluation of this algorithm framework found that while this tool represents an important first step in larger-scale near real-time landslide hazard assessment efforts, it requires several modifications before it can be fully realized as an operational tool. This study draws upon a prior work's recommendations to develop a new approach for considering landslide susceptibility and hazard at the regional scale. This case study calculates a regional susceptibility map using remotely sensed and in situ information and a database of landslides triggered by Hurricane Mitch in 1998 over four countries in Central America. The susceptibility map is evaluated with a regional rainfall intensity-duration triggering threshold and results are compared with the global algorithm framework for the same event. Evaluation of this regional system suggests that this empirically based approach provides one plausible way to approach some of the data and resolution issues identified in the global assessment. The presented methodology is straightforward to implement, improves upon the global approach, and allows for results to be transferable between regions. The results also highlight several remaining challenges, including the empirical nature of the algorithm framework and adequate information for algorithm validation. Conclusions suggest that integrating additional triggering factors such as soil moisture may help to improve algorithm performance accuracy. The regional algorithm scenario represents an important step forward in advancing regional and global-scale landslide hazard assessment.

This study describes and maps the geohazards that may affect the Egirdir (Isparta) settlement area. For these purposes, field studies were performed, and the data obtained were compiled using Geographical Information Systems (GIS). Four different types of earth slump were identified: paleo, small-scale shallow, active and potential earth slump. In addition, two rockfall source areas were identified and mapped. The ratio of the area affected by rockfall to the total area is 2.03%. Although there is no expected risk associated with active earth slump, displacement in the potential earth slump area represents a risk. The risk level calculated is 1.5% for 1 year. Based on all of the data, a geohazard reconnaissance map of the study area was prepared. Based on this map, it can be concluded that 83% of the overall study area has no risk of mass movement.

The rock surface and geometry of the colluviums were found by integrating ERT and borehole data. The iso-resistivity line in the bedrock broadly followed the bedding plane, indicating that the contribution of lithology to resistivity exceeds that of groundwater. The results of single-point-resistance logging with time-lapse and borehole data reveal that the bedrock has low permeability, which is associated with poorly developed joints and fractures. The fine grain content part (including the clayey layer), almost parallel to the bedding plane of the bedrock and between the colluvium and the bedrock in the upper part of the landslide, served as the slip surface and is believed to have been recently produced. It can block and retain water in the colluviums. Accordingly, this slip surface has the potential to re-slip in the future. Another slope failure involved rock collapse by a well-developed open release joint close to the Huoshaoping Terrace. It is also related to groundwater flow over a large gradient from the Huoshaoping Terrace. It is a key to determining whether this landslide will expand in the future.

Global climate change coupled with human activities is eroding the mountain regions of the world at an alarming rate. The various types of erosion can be classified as water erosion, aeolian erosion, glaciered erosion, gravity erosion and man-made erosion. Tectonic activity also plays a major role towards mountain erosion. Soil erosion along with debris flow and rock falling not only causes loss of human life and property, but also affects the climatic condition of the mountain regions. Mountain erosion mitigation and protection methods include wire mesh fencing with inclusion of brush layers and brush mats on fascines, constructing check dams and slope benches and application of bioengineering works such as plantation and vegetation growth. This study consists of the global scenario with some of the state-of-the-art methods for mitigation and mappings of mountain erosion. The erosion in mountainous regions can be controlled with the help of suitable vegetation and plant growth, with installation of special bioengineered materials. However, public awareness is also considered as an important factor. Moreover, it is found that mapping the rate of erosion greatly helps to make proper action plan against the erosion process.

In this study, static and pseudostatic analyses of slope stability for earthquake conditions were carried out in the Gurpinar area. In situ testing (SPT) was carried out and laboratory samples were obtained from six boreholes (maximum depth 50.0 m) to determine soil classification and strength characteristics. Geophysical studies (seismic refraction and MASW) were also carried out in the area to estimate the structure and stiffness strength characteristics of the slope to 50.0 m depth. All field and laboratory data were used to determine the mechanical and structural (geometrical) behavior of the slope. In order to solve the slope stability problem, three soil slope models were considered. Pseudostatic analysis was carried out to estimate the earthquake acceleration seismic hazard in the region. These analyses showed that, while there was no potential slope instability under static load conditions, some problems would appear with increasing earthquake acceleration. A geotechnical slope improvement project is proposed for the study area.

This study examines the use of geographic information system (GIS) technology and Bayesian statistics in creating a suitable landslide hazard-zone map of good predictive power. A total of 2,036 landslides were interpreted from high-resolution aerial photographs and multi-source satellite images pre- and post-earthquake, and verified by selected field checking before a final landslide-inventory map of the study area could be established using GIS software. The 2,036 landslides were randomly partitioned into two subsets: a training dataset, which contains 80 % (1,628 landslides), for training the model; and a testing dataset 20 % (408 landslides). Twelve earthquake triggered landslide associated controlling parameters, such as elevation, slope gradient, slope aspect, slope curvature, topographic position, distance from main surface ruptures, peak ground acceleration, distance from roads, normalized difference vegetation index, distance from drainages, lithology, and distance from all faults were obtained from variety of data sources. Landslide hazard indices were calculated using the weight of evidence model. The landslide hazard map was compared with training data and testing data to obtain the success rate and predictive rate of the model, respectively. The validation results showed satisfactory agreement between the hazard map and the existing landslide distribution data. The success rate is 80.607 %, and the predictive rate is 78.855 %. The resulting landslide hazard map showed five classes of landslide hazard, i.e., very high, high, moderate, low and very low. The landslide hazard evaluation map should be useful for environmental recovery planning and reconstruction work.

In a certain area, a combination of measurement of cracks and seismic refraction method can provide a better knowledge of the future behavior of the area in terms of its stability. In this reconnaissance study, seismic refraction method and continuous measurements of crack displacement were conducted to detect the stability of an area that lies on the downstream side of the Mosul dam, and to establish its possible mechanisms of failure. The study shows two types of instability, namely, fall and sliding, and these were due to heavy rainfall, springs, and spillway operation.

The catastrophic landslide of 1977 together with surrounding landslides in the Lubietova area were analysed with the help of persistent scatterers (PS) technique in order to evaluate recent and past deformations of the unstable slopes. Although long-term precise geodetic monitoring of the 1977 landslide revealed differential deformations inside the sliding mass, due to the lack of the PS located inside the landside caused by temporal decorrelation, unfortunately, these records could not be directly compared. The adjacent landslides with sufficient number of PS were analysed by transformation of the line of sight displacements recorded by the sensors to the slope vector direction. This procedure allowed identification of the precise boundaries of the actively moving landslide parts and the updating of the landslide inventory for the Lubietova area.

Here, the aim is to perform a more detailed extreme value analysis using the critical threshold that enables definition of the level-crossing event. It will be rigorously proven that the approximations and baseline methods previously used yield important intuitive conclusions about the impact of low measurement noise and high levels on improved capability of level-crossing predictors. Where possible, elegant closed-form solutions for a well-known alarm system metric in face of those limiting considerations are also provided.

Despite its importance, groups that actively fix N sub(2) and contribute to the input of organic N in these ecosystems still remain largely unclear. To investigate the active diazotrophic community in microbial mats from the Elkhorn Slough estuary, Monterey Bay, CA, USA, we conducted an extensive combined approach, including biogeochemical, molecular and high-resolution secondary ion mass spectrometry (NanoSIMS) analyses. Detailed analysis of dinitrogenase reductase (nifH) transcript clone libraries from mat samples that fixed N sub(2) at night indicated that cyanobacterial nifH transcripts were abundant and formed a novel monophyletic lineage. Independent NanoSIMS analysis of super(15)N sub(2)-incubated samples revealed significant incorporation of super(15)N into small, non-heterocystous cyanobacterial filaments. Mat-derived enrichment cultures yielded a unicyanobacterial culture with similar filaments (named Elkhorn Slough Filamentous Cyanobacterium-1 (ESFC-1)) that contained nifH gene sequences grouping with the novel cyanobacterial lineage identified in the transcript clone libraries, displaying up to 100% amino-acid sequence identity. The 16S rRNA gene sequence recovered from this enrichment allowed for the identification of related sequences from Elkhorn Slough mats and revealed great sequence diversity in this cluster. Furthermore, by combining super(15)N sub(2) tracer experiments, fluorescence in situ hybridization and NanoSIMS, in situ N sub(2) fixation activity by the novel ESFC-1 group was demonstrated, suggesting that this group may be the most active cyanobacterial diazotroph in the Elkhorn Slough mat. Pyrotag sequences affiliated with ESFC-1 were recovered from mat samples throughout 2009, demonstrating the prevalence of this group. This work illustrates that combining standard and single-cell analyses can link phylogeny and function to identify previously unknown key functional groups in complex ecosystems.

Models for an abiologic origin for these assemblages required the presence of graphite, and this study is the first report of graphite within ALH 84001. The graphite occurs as hollow spheres (nano-onions), filaments, and highly crystalline particles in intimate association with magnetite in the carbonate globules. In addition to supporting an abiologic origin for the carbonate globule assemblages in ALH 84001, this work proves that there is an inventory of reduced-carbon phases on Mars that has not yet been thoroughly investigated.

AN - 1024664410; 16864795 AB - In this study, we evaluate the fidelity of current climate models in simulating the two types of El Nino events using the pre-industrial output in CMIP3 archives. It is shown that a few climate models simulate the two types of El Nino events to some extent, while most of the models have serious systematic problems in simulating distinctive patterns of sea-surface temperature (SST) and precipitation anomaly associated with the two types of El Nino; that is, they tend to simulate a single type of El Nino. It is shown that the ability of climate models in simulating the two types of El Nino is related to the sensitivity of the atmospheric responses to the SST anomaly patterns. Models whose convective location is shifted to the east (west) as the SST anomaly center moves to the east (west) tends to simulate the two types of El Nino events successfully. On the other hand, models whose location of convective anomaly is confined over the western or central Pacific tends to simulate only the single type of El Nino event. It is also shown that the confinement of the convective anomaly over the western or central Pacific is closely linked to the dry bias and the associated cold bias over the eastern Pacific. That is, because positive El Nino SST anomalies over the eastern Pacific cannot increase local convection effectively when the total SSTs are still too cold due to a cold bias. This implies that the realistic simulation of climatology, especially over the equatorial eastern Pacific, is essential to the successful simulation of the two types of El Nino.

Microbial communities in the rhizosphere are crucial to nutrient and organic matter cycling within agroecosystems. The overall aim of this study was to investigate the impacts of crop management on microbial community structure and processing of rhizodeposit-C within microenvironments of two soil zones, the rhizosphere versus non-rhizosphere. Methods: New root-C (C sub(new)) from super(13)C-labeled hairy vetch (Vicia dasycarpa) plants were traced into phospholipid fatty acids (PLFA) within microaggregate (53-250 mu m) and silt-and-clay (<53 mu m) microenvironments in rhizosphere and non-rhizosphere soil during the cover crop growing season in long-term conventional (annual synthetic fertilizer applications), low-input (synthetic fertilizer and cover crop applied in alternating years), and organic (annual composted manure and cover crop additions) maize-tomato systems (Zea mays L.- Lycopersicum esculentum L.). Results: Among the three cropping systems, the composition of the microbial communities processing root-derived C were similar, which implied that the cropping systems maintained diverse microbial communities that were capable of utilizing similar C substrates despite receiving different long-term nutrient inputs. Relative distributions of root-derived PLFA-C ( super(13)C mol%) in the rhizosphere and non-rhizosphere were not significantly different, thereby suggesting that the structure of the microbial community utilizing new root-C in the rhizosphere- and non-rhizosphere microenvironments were similar. However, total PLFA biomass was four times greater, and root-derived PLFA-C in both soil microenvironments were approximately 10 times greater in the rhizosphere than in the non-rhizosphere. Although no microbial group dominated the processing of C sub(new) in the microenvironments of the rhizosphere and non-rhizosphere, we found that the microbial community of the silt-and-clay in the rhizosphere played a different role in the cycling of C sub(new) compared to communities in the rhizosphere microaggregates and those in the silt-and-clay and microaggregates of the non-rhizosphere. Conclusions: Our results confirm that rhizodeposition plays an important role in the greater contribution of root-C than residue-C to SOM stabilization. This study also showed that microbial communities assimilating rhizodeposit-C are sensitive to their microenvironment (i.e., microaggregates versus silt-and-clay particles); nevertheless, differences in long-term crop management did not lead to differences in the capacity of the microbial communities to utilize active cover crop root-C substrates.

A visual dependence score was determined for each subject, and this score was used to explore how visual dependency was linked to locomotor performance (1) during three training sessions and (2) in a new discordant environment presented at the conclusion of training. Performance measures included reaction time (RT), stride frequency (SF), and heart rate (HR), which respectively served as indicators of cognitive load, postural stability, and anxiety. We hypothesized that training would affect performance measures differently for highly visually dependent individuals than for their less visually dependent counterparts. A seemingly unrelated estimation analysis of RT, SF, and HR revealed a significant omnibus interaction of visual dependency by session (p < 0.001), suggesting that the magnitude of differences in these measures across training day 1 (TD1), training day 3 (TD3), and exposure to a novel test is dependent on subjects' levels of visual dependency. The RT result, in particular, suggested that highly visually dependent subjects successfully trained to one set of sensory discordant conditions but were unable to apply their adapted skills when introduced to a new sensory discordant environment. This finding augments rationale for developing customized gait training programs that are tailored to an individual. It highlights one factor-personal level of visual dependency-to consider when designing training conditions for a subject or patient. Finally, the link between visual dependency and locomotor performance may offer predictive insight regarding which subjects in a normal population will require more training when preparing for specific novel locomotor conditions.

In this study we analyzed the concentration of organic and inorganic carbon and their relationship with in situ climatic and geological characteristics in 485 samples of surface soil and 17 pits from the hyper-arid area and 51 samples with 2 pits from the arid-semiarid region from the Atacama Desert located in Peru and Chile. The soil organic carbon (SOC) in hyperarid soils ranged from 1.8 to 50.9 mu gC per g of soil for the 0-0.1m profile and from 1.8 to 125.2 mu gC per g of soil for the 0-1m profile. The analysis of climatic (temperature and precipitation), elevation, and some geologic characteristics (landforms) associated with hyper-arid soils explained partially the SOC variability. On the other hand, soil inorganic carbon (SIC) contents, in the form of carbonates, ranged from 200 to 1500 mu gC per g of soil for the 0-0.1m profile and from 200 to 3000 mu gC per g of soil for the 0-1.0m profile in the driest area. The largest accumulations of organic and inorganic carbon were found near to arid-semiarid areas. In addition, the elemental carbon concentrations show that the presence of other forms of inorganic carbon (e.g. graphite, etc.) was negligible in these hyperarid soils. Overall, the top 1m soil layer of hyperarid lands contains similar to 11.6Tg of organic carbon and 344.6Tg of carbonate carbon. The total stored carbon was 30.8-fold the organic carbon alone. To our knowledge, this is the first study evaluating the total budget carbon on the surface and shallow subsurface on similar to 160,000km2 of hyperarid soils.

Given the importance of this topic, we review how satellite observations contribute toward improving the representation of biomass burning quantitatively in climate and air-quality modeling and assessment. Satellite observations related to biomass burning may be classified into five broad categories: (i) active fire location and energy release, (ii) burned areas and burn severity, (iii) smoke plume physical disposition, (iv) aerosol distribution and particle properties, and (v) trace gas concentrations. Each of these categories involves multiple parameters used in characterizing specific aspects of the biomass-burning phenomenon. Some of the parameters are merely qualitative, whereas others are quantitative, although all are essential for improving the scientific understanding of the overall distribution (both spatial and temporal) and impacts of biomass burning. Some of the qualitative satellite datasets, such as fire locations, aerosol index, and gas estimates have fairly long-term records. They date back as far as the 1970s, following the launches of the DMSP, Landsat, NOAA, and Nimbus series of earth observation satellites. Although there were additional satellite launches in the 1980s and 1990s, space-based retrieval of quantitative biomass burning data products began in earnest following the launch of Terra in December 1999. Starting in 2000, fire radiative power, aerosol optical thickness and particle properties over land, smoke plume injection height and profile, and essential trace gas concentrations at improved resolutions became available. The 2000s also saw a large list of other new satellite launches, including Aqua, Aura, Envisat, Parasol, and CALIPSO, carrying a host of sophisticated instruments providing high quality measurements of parameters related to biomass burning and other phenomena. These improved data products have enabled significant progress in the study of biomass burning from space. However, appreciable uncertainty remains in many of the measurements that still need to be addressed. Nevertheless, climate and other atmospheric models are making significant adjustments to take advantage of quantitative satellite measurements in studying biomass burning activity, emissions, and impacts. New research directions should include not only improvements in satellite retrievals and modeling accuracies, but also increased synergy between them, such that satellite measurements can be directly input into models without requiring elaborate interpretation.

In this study, anomalies of terrestrial water storage (TWS) observed by the Gravity Recovery and Climate Experiment (GRACE) satellite mission were assimilated into the NASA Catchment land surface model in western and central Europe for a 7-year period, using a previously developed ensemble Kalman smoother. GRACE data assimilation led to improved runoff estimates (in temporal correlation and root mean square error) in 17 out of 18 hydrological basins, even in basins smaller than the effective resolution of GRACE. Improvements in root zone soil moisture were less conclusive, partly due to the shortness of the in situ data record. GRACE data assimilation also had significant impacts in groundwater estimates including trend and seasonality. In addition to improving temporal correlations, GRACE data assimilation also reduced increasing trends in simulated monthly TWS and runoff associated with increasing rates of precipitation. The assimilation downscaled (in space and time) and disaggregated GRACE data into finer scale components of TWS which exhibited significant changes in their dryness rankings relative to those without data assimilation, suggesting that GRACE data assimilation could have a substantial impact on drought monitoring. Signals of drought in GRACE TWS correlated well with MODIS Normalized Difference Vegetation Index (NDVI) data in most areas. Although they detected the same droughts during warm seasons, drought signatures in GRACE derived TWS exhibited greater persistence than those in NDVI throughout all seasons, in part due to limitations associated with the seasonality of vegetation. Mass imbalances associated with GRACE data assimilation and challenges of using GRACE data for drought monitoring are discussed.

The quantitative studies show that the CO (sub 2) is dispersed in the ice; its column density increases with ion fluence to a maximum value (in 10 (super 15) molecules cm (super -2) ) of approximately 1 at 20 K and approximately 3 at 120 K. The initial yield is 0.05 (0.1) CO (sub 2) per incident H (super +) at 20 (120) K. The CO (sub 2) destruction process, which limits the maximum column density, occurs with an effective cross section of approximately 2.5 (4.1)X10 (super -17) cm (super 2) at 20 (120) K. We discuss radiation-induced oxidation by reactions of radicals in water with the carbon surface and demonstrate that these reactions can be a significant source of condensed carbon dioxide in interstellar grains and in icy satellites in the outer solar system.

We further present millimeter and radio data obtained with the Submillimeter Array, the Combined Array for Research in Millimeter-wave Astronomy, and the Expanded Very Large Array during the first three weeks after explosion. Combining these observations with early optical photometry, we show that the panchromatic data set is well described by non-thermal synchrotron emission (radio/mm) with inverse Compton scattering (X-ray) of a thermal population of optical photons. In this scenario, the shock partition fractions deviate from equipartition by a factor, (epsilon (sub e ) /epsilon (sub B ) ) approximately 30. We derive the properties of the shock wave and the circumstellar environment and find a time-averaged shock velocity of (sub IMG .../ (super and a progenitor mass-loss rate of (sub IMG .../ (super (for an assumed wind velocity, v (sub w) = 1000 km s (super -1) ). We show that these properties are consistent with the sub-class of Type IIb SNe characterized by compact progenitors (Type cIIb) and dissimilar from those with extended progenitors (Type eIIb). Furthermore, we consider the early optical emission in the context of a cooling envelope model to estimate a progenitor radius of R (sub *) nearly equal 10 (super 11) cm, in line with the expectations for a Type cIIb SN. Together, these diagnostics are difficult to reconcile with the extended radius of the putative yellow supergiant progenitor star identified in archival Hubble Space Telescope observations, unless the stellar density profile is unusual. Finally, we searched for the high-energy shock breakout pulse using X-ray and gamma-ray observations obtained during the purported explosion date range. Based on the compact radius of the progenitor, we estimate that the shock breakout pulse was detectable with current instruments but likely missed due to their limited temporal/spatial coverage. Future all-sky missions will regularly detect shock breakout emission from compact SN progenitors enabling prompt follow-up observations with sensitive multi-wavelength facilities.

We obtained good coverage around the double peak structure in the light curve via follow-up observations from different observatories. The binary lens model that includes the effects of parallax (known orbital motion of the Earth) and orbital motion of the lens yields a binary lens mass ratio of q = 0.321 + or - 0.007 and a projected separation of s = 0.072 + or - 0.001 in units of the Einstein radius. The parallax parameters allow us to determine the lens distance D (sub L) = 3.11 + or - 0.39 kpc and total mass M (sub L) = 1.40 + or - 0.18 M (sub �) ; this leads to the primary and secondary components having masses of M (sub 1) = 1.06 + or - 0.13 M (sub �) and M (sub 2) = 0.34 + or - 0.04 M (sub �) , respectively. The parallax model indicates that the binary lens system is likely constructed by the main-sequence stars. On the other hand, we used a Bayesian analysis to estimate probability distributions by the model that includes the effects of xallarap (possible orbital motion of the source around a companion) and parallax (q = 0.270 + or - 0.005, s = 0.083 + or - 0.001). The primary component of the binary lens is relatively massive, with M (sub 1) = 0.9 (super +4.6) (sub -0.3) M (sub �) and it is at a distance of D (sub L) = 2.6 (super +3.8) (sub -0.9) kpc. Given the secure mass ratio measurement, the companion mass is therefore M (sub 2) = 0.2 (super +1.2) (sub -0.1) M (sub �) . The xallarap model implies that the primary lens is likely a stellar remnant, such as a white dwarf, a neutron star, or a black hole. Copyright (Copyright) 2012. The American Astronomical Society.

N1 - Last updated - 2012-06-19 ER - TY - JOUR T1 - Puncturing Mars; how impact craters interact with the Martian cryosphere AN - 1080607813; 2012-083873 AB - Geologic evidence suggests that the Martian surface and atmospheric conditions underwent major changes in the late Noachian, with a decline in observable water-related surface features, suggestive of a transition to a dryer and colder climate. Based on that assumption, we have modeled the consequences of impacts into a approximately 2-6 km-thick cryosphere. We calculate that medium-sized (few 10 s of km diameter) impact craters can physically and/or thermally penetrate through this cryosphere, creating liquid water through the melting of subsurface ice in an otherwise dry and frozen environment. The interaction of liquid water with the target rock produces alteration phases that thermochemical modeling predicts will include hydrous silicates (e.g., nontronite, chlorite, serpentine). Thus, even small impact craters are environments that combine liquid water and the presence of alteration minerals that make them potential sites for life to proliferate. Expanding on the well-known effects of large impact craters on target sites, we conclude that craters as small as approximately 5-20 km (depending on latitude) excavate large volumes of material from the subsurface while delivering sufficient heat to create liquid water (through the melting of ground ice) and drive hydrothermal activity. This connection between the surface and subsurface made by the formation of these small, and thus more frequent, impact craters may also represent the most favorable sites to test the hypothesis of life on early Mars.

Locally preserved textures formed by partial replacement of coarse olivine by serpentine in the carbonaceous chondrite Nogoya (CM2) establish unique associations between each individual mass of serpentine and the specific olivine from which that serpentine formed. Electron probe microanalyses show that the composition of serpentine replacing coarse olivine is uniform throughout all analyzed volumes of Nogoya, and is independent of the composition of the olivine being replaced. If, as previously proposed, late-stage alteration fluids were Mg-rich because Fe-source minerals were depleted in earlier stages, then the uniform Mg-rich composition of the serpentine replacing large silicate grains during advanced stages of alteration may indicate diffusional homogenization of the aqueous solutions over progressively larger spatial scales, enabled by long timescales and previously proposed stagnant or slow-moving fluids. The range of olivine compositions replaced in Nogoya is even larger than previously reported from ALH 81002 (CM2). This militates against hypotheses of strong primary-mineral control on the compositions of alteration products, at least at advanced stages of alteration. The serpentine formed by olivine replacement in Nogoya is more magnesian than the counterpart serpentine replacing all anhydrous primary silicates in ALH 81002. This intermeteorite heterogeneity of replacement-serpentine composition between ALH 81002 and Nogoya indicates that the aqueous solutions in which the olivine-serpentine replacement reactions occurred were of different compositions in the two different CM parent-body volumes sampled by ALH 81002 and Nogoya. The more magnesian character of serpentines in Nogoya than in ALH 81002 indicates that the Nogoya aqueous-alteration environment was even more highly evolved toward Mg-rich solutions than the environment indicated by the composition of the serpentine in ALH 81002. Persistence of primary-silicate remnants within centripetal and meshwork serpentine indicates that either the aqueous alteration episodes in the parent-body volumes represented by individual meteorites were too short to allow complete replacement of olivine by serpentine, or one or more reactants (most likely water) were completely consumed before the coarse primary silicate was completely replaced. Seemingly incompatible arguments for and against primary-mineral control of serpentine composition during CM chondrite alteration may be reconciled by considering the different grain sizes and reaction timescales that likely existed in different textural settings.

Surviving fragments of projectiles in the lunar regolith provide a direct measure of the types and thus the sources of exogenous material delivered to the Earth-Moon system. In ancient [>3.4 billion years ago (Ga)] regolith breccias from the Apollo 16 landing site, we located mineral and lithologic relics of magnesian chondrules from chondritic impactors. These ancient impactor fragments are not nearly as diverse as those found in younger (3.4 Ga to today) regolith breccias and soils from the Moon or that presently fall as meteorites to Earth. This suggests that primitive chondritic asteroids, originating from a similar source region, were common Earth-Moon-crossing impactors during the latter stages of the basin-forming epoch.

We find that water ice on the surface of these objects occurs in three separate manners: (1) Haumea family members uniquely show surfaces of nearly pure water ice, presumably a consequence of the fragmentation of the icy mantle of a larger differentiated proto-Haumea; (2) large objects with absolute magnitudes of H < 3 (and a limited number to H = 4.5) have surface coverings of water ice-perhaps mixed with ammonia-that appears to be related to possibly ancient cryovolcanism on these large objects; and (3) smaller KBOs and centaurs which are neither Haumea family members nor cold-classical KBOs appear to divide into two families (which we refer to as "neutral" and "red"), each of which is a mixture of a common nearly neutral component and either a slightly red or very red component that also includes water ice. A model suggesting that the difference between neutral and red objects due to formation in an early compact solar system either inside or outside, respectively, of the approximately 20 AU methanol evaporation line is supported by the observation that methanol is only detected on the reddest objects, which are those which would be expected to have the most of the methanol containing mixture.

Consistent with the findings of previous work in the visible light range with these rocks, and in analogous sediments, blue wavelengths are more strongly attenuated than red. At wavelengths from 2400-1200 nm the absorption of the dry rock layer is roughly constant at 3.1 except in the water bands at 2000 nm and 1600 nm. From 1200-300 nm the absorption increases from 3.1 to 6.4, below 300-190 nm (the lowest wavelength measured) the absorption exceeds 6.4. When the rock is saturated with water the absorption uniformly decreases by about 0.1-0.2 over the 700-400 nm region but decreases sharply for lower wavelengths, with the decrease equal to 0.5 at 300 nm. Thus, the relative protection against UV is attenuated when the rock is wet. Even with this decreased absorption the UV absorption is still greater than that for the visible. The absorption at wavelengths less than 300 nm was too large to measure (> 6.4) for both the wet and dry rocks.

Four discrete buried snowpacks are studied within Pearse Valley, Antarctica, through in situ observations, sample analyses, O-H isotope measurements and numerical modelling of snowpack stability and evolution. The buried snowpack deposits evolve throughout the year and undergo deposition, melt, refreeze, and sublimation. We demonstrate how the deposition and subsequent burial of snow can preserve the snowpacks in the Dry Valleys. The modelled lifetimes of the buried snowpacks are dependent upon subsurface stratigraphy but are typically less than one year if the lag thickness is less than c. 7 cm and snow thickness is less than c. 10 cm, indicating that some of the Antarctic buried snowpacks form annually. Buried snowpacks in the Antarctic polar desert may serve as analogues for similar deposits on Mars and may be applicable to observations of the north polar erg, buried ice at the Mars Phoenix landing site, and observations of buried ice throughout the martian Arctic. Numerical modelling suggests that seasonal snows and subsequent burial are not required to preserve the snow and ice on Mars.

In preparation for the 2008 Phoenix Mars mission, we conducted an interdisciplinary investigation comparing the biological, mineralogical, chemical, and physical properties of wetter lower Taylor Valley (TV) soils to colder, drier University Valley (UV) soils. Our analyses were performed for each horizon from the surface to the ice table. In TV, clay-sized particle distribution and less abundant soluble salts both suggested vertical and possible horizontal transport by water, and microbial biomass was higher. Alteration of mica to short-order phyllosilicates suggested aqueous weathering. In UV, salts, clay-sized materials, and biomass were more abundant near the surface, suggesting minimal downward translocation by water. The presence of microorganisms in each horizon was established for the first time in an ultraxerous zone. Higher biomass numbers were seen near the surface and ice table, perhaps representing locally more clement environments. Currently, water activity is too low to support metabolism at the Phoenix site, but obliquity changes may produce higher temperatures and sufficient water activity to permit microbial growth, if the populations could survive long dormancy periods ( similar to 10 super(6) years).

Faults often lead to genomic instability, cell cycle arrests and disease onset. These key structural changes are under tight spatial-temporal and post-translational control, with crucial roles for reversible protein phosphorylation. The phosphoprotein phosphatases PP1 and PP2A are paramount for the timely execution of mitotic entry and exit but their interaction partners and substrates are still largely unresolved. High throughput, mass-spectrometry based studies have limited sensitivity for the detection of low-abundance and transient complexes, a typical feature of many protein phosphatase complexes. Moreover, the limited timeframe during which mitosis takes place reduces the likelihood of identifying mitotic phosphatase complexes in asynchronous cells. Hence, numerous mitotic protein phosphatase complexes still await identification. Here we present a strategy to enrich and identify serine/threonine protein phosphatase complexes at the mitotic spindle. We thus identified a nucleolar RNA helicase, Ddx21/Gu, as a novel, direct PP1 interactor. Furthermore, our results place PP1 within the toposome, a Topoisomerase II alpha (TOPOIIα) containing complex with a key role in mitotic chromatin regulation and cell cycle progression, possibly via regulated protein phosphorylation. This study provides a strategy for the identification of further mitotic PP1 partners and the unravelling of PP1 functions during mitosis.

Due to the ill-posed inverse problem of ECT, images reconstructed using conventional linear algorithms often suffer from limitations such as low resolution and blurred edges. Hence, new efficient high-resolution nonlinear imaging algorithms are needed for accurate two-phase imaging. The proposed Iterative Nonlinear Tikhonov-regularized Algorithm with Constraints (INTAC) is based on an efficient finite element method (FEM) forward model of quasi-static electromagnetic problem. It iteratively minimizes the discrepancy between FEM simulated and actual measured capacitances by adjusting the reconstructed image using the Tikhonov regularized method. More importantly, it enforces the known permittivity of two phases to the unknown pixels which exceed the reasonable range of permittivity in each iteration. This strategy does not only stabilize the converging process, but also produces sharper images. Simulations show that resolution improvement of over 2 times can be achieved by INTAC with respect to conventional approaches. Strategies to further improve spatial imaging resolution are suggested, as well as techniques to accelerate nonlinear forward model and thus increase the temporal resolution.

The image they saw as their spacecraft cleared the lunar horizon on its fourth orbit caught them by surprise and so captivated them that they were moved to take photographs. One of these, taken by Astronaut William Anders, became something of a global icon. Known as Earthrise, it shows Earth as it "rises" above the Moon's surface. This image captured the public's imagination and galvanized thinking about the impact we might have on our environment. It was so powerful that it has been called one of the most influential photographs in the history of environmental thought--and deed! Based on this impact, in 1969 Senator Gaylord Nelson, who had witnessed firsthand the ravages of an oil spill in Santa Barbara, CA, was inspired to take action. Taking advantage of the rising public consciousness that the Earthrise photograph had created, he managed to redirect the attention of the public toward issues related to air and water pollution.

Likewise, the water turbidity trend was determined at a site near the Bay for each of four major tributaries to Tampa Bay (Hillsborough River, the Alafia River, the Little Manatee River, and the Manatee River). This study identifies consistent changes in LCLU across the Tampa Bay watershed and a decrease in water turbidity. LCLU change analysis as a percent of the total Tampa Bay watershed revealed an increase of 2.6% in developed area followed by a 0.9% in bare land and a 0.6% in water cover. A decrease of 1.8% of the total Tampa Bay watershed was found in agriculture, followed in order by 1.1% in wetland and 1.4% in scrub/shrub. Other land classes changed less than 0.2% of the total watershed. A linear mixed model (SAS procedure PROC MIXED) revealed an overall decreasing trend in water turbidity (p=0.003, slope estimate=-0.02) across the four major Tampa Bay tributaries considered. This study suggests that development (urbanization) could be associated with decreasing water turbidity in Tampa Bay. Finally, although these results may help explain similar effects on other water bodies with similar conditions of adjacent urbanization and low slope, more analysis are needed considering a larger number of watersheds with similar scales and longer time period in order to confirm that the findings of this study are generally evident.

Accepted for publication December 7, 2010. Background: Elderly patients comprise an increasing proportion of intensive care unit (ICU) admissions. Advanced age and multiple comorbidities compromise their immunity and hence they may be more prone to succumbing to severe infection and have poorer outcome. We undertook this study to review impact of severe sepsis on mortality in the elderly patients. Methods: All patients admitted to a medical ICU of a tertiary care institute with severe sepsis or septic shock were prospectively included. Patients were divided into young (age below 60 years), old (age between 60 and 80 years), and very old (age above 80 years) groups. Data regarding baseline patient characteristics, admission APACHE II score, and ICU course including need for organ support and ICU length of stay were noted. Categorical data were analyzed using chi 2 or Fisher Exact test as appropriate and continuous data were analyzed using Student t test. Primary outcome measure was the ICU mortality. Results: Of 387 patients with sepsis, 132 patients who fulfilled the criteria for severe sepsis/septic shock were included in the analysis. The most common suspected site of infection was lungs (45.5%), followed by urinary tract (21.2%) and abdomen (16.7%). Intensive care unit mortality in younger patients was 45.6% as compared to 60.7% in old and 78.9% in very old patients (P = .035). The relative risk (RR) for dying in the old age was 1.125 and RR for dying in the very old age group was 1.487 as compared to the young patients. There was an increased need for organ support in the elderly and very elderly population as compared to the younger population. On multivariate analysis, only age of the patient was found to be independently predicting ICU mortality (P = .002, OR: 1.038, 95% CI: 1.014-1.062). Conclusions: The risk of dying from severe sepsis is considerably higher in the elderly and very elderly subgroup of patients with age as an independent risk factor for mortality. Hence, early aggressive care to recognize and manage severe sepsis is required to improve outcome.

The fate of anhydrite-, calcite-bearing crust during a meteoroid impact must be addressed in order to evaluate: (1) the potential S- and C-gas release to the atmosphere, (2) the formation of S- and C-rich melts, and (3) the crystallization of S- and C-rich minerals which may be recognized by spectral analyses of planetary surfaces. We performed piston-cylinder experiments at 1 GPa, between 1200 and 1750 degrees C, on a mixture of 70 wt.% tholeiitic basalt+15 wt.% anhydrite+15 wt.% calcite. Up to approximately 1440 degrees C, an ultracalcic (CaO>19.8 wt.%; CaO/Al (sub 2) O (sub 3) >1 wt.%) picrobasaltic (SiO (sub 2) approximately 39-43 wt.%; Na (sub 2) O+K (sub 2) O<2 wt.%) melt containing up to 5.7 wt.% SO (sub 3) and up to 5.1 wt.% CO (sub 2) +H (sub 2) O (calculated by difference) is present in equilibrium with fassaitic clinopyroxene, anhydrite, scapolite, chromian spinel and a gas composed mainly of CO and, occasionally, aliphatic thiols like CH (sub 3) (CH (sub 2) ) (sub 3) SH. Hydrogen was incorporated either by contact between the starting material and air or by diffusion through the capsule during the experiments. Above approximately 1440 degrees C, a CaO-rich ( approximately 35 wt.%) sulfate-carbonate (SC) melt which contains 41-47 wt.% SO (sub 3) , 7-12 wt.% CO (sub 2) +H (sub 2) O and a few percent of Na (sub 2) O, forms in equilibrium with the picrobasaltic melt. This study shows that a meteoroid impact onto an anhydrite- and calcite-bearing basaltic crust is likely to release CO gas to the atmosphere, while S is trapped in solid or liquid phases. Under hydrous conditions, however, the S/C in the gas may increase. The importance of the temperature parameter on the impact phase relations is also demonstrated. In particular, SC melt may form by meteoroid impact, and flow rapidly on a planetary surface. Physical modeling must therefore be combined with high P-high T phase diagrams of complex assemblages similar to planetary lithologies in order to evaluate the effects of a meteoroid impact.

Abundant steep slopes indicate that impact-generated surface regolith is underlain by bedrock. Dawn observations confirm the large impact basin (Rheasilvia) at Vesta's south pole and reveal evidence for an earlier, underlying large basin (Veneneia). Vesta's geology displays morphological features characteristic of the Moon and terrestrial planets as well as those of other asteroids, underscoring Vesta's unique role as a transitional solar system body.

The signature of deep lithologies excavated during the formation of the Rheasilvia Basin on the south pole has been preserved on the surface. Color variations (band depth, spectral slope, and eucrite-diogenite abundance) clearly correlate with distinct compositional units. Vesta displays the greatest variation of geometric albedo (0.10 to 0.67) of any asteroid yet observed. Four distinct color units are recognized that chronicle processes--including impact excavation, mass wasting, and space weathering--that shaped the asteroid's surface. Vesta's color and photometric diversity are indicative of its status as a preserved, differentiated protoplanet.

There are considerable regional and local variations across the asteroid: Spectrally distinct regions include the south-polar Rheasilvia Basin, which displays a higher diogenitic component, and equatorial regions, which show a higher eucritic component. The lithologic distribution indicates a deeper diogenitic crust, exposed after excavation by the impact that formed Rheasilvia, and an upper eucritic crust. Evidence for mineralogical stratigraphic layering is observed on crater walls and in ejecta. This is broadly consistent with magma-ocean models, but spectral variability highlights local variations, which suggests that the crust can be a complex assemblage of eucritic basalts and pyroxene cumulates. Overall, Vesta mineralogy indicates a complex magmatic evolution that led to a differentiated crust and mantle JF - Science AU - De Sanctis, Maria Cristina AU - Ammannito, E AU - Capria, M T AU - Tosi, F AU - Capaccioni, F AU - Zambon, F AU - Carraro, F AU - Fonte, S AU - Frigeri, A AU - Jaumann, Ralf AU - Magni, G AU - Marchi, Simone AU - McCord, T B AU - McFadden, Lucy A AU - McSween, Harry Y AU - Mittlefehldt, David W AU - Nathues, A AU - Palomba, E AU - Pieters, Carle M AU - Raymond, C A AU - Russell, Christopher T AU - Toplis, M J AU - Turrini, D Y1 - 2012/05/11/ PY - 2012 DA - 2012 May 11 SP - 697 EP - 700 PB - American Association for the Advancement of Science, Washington, DC VL - 336 IS - 6082 SN - 0036-8075, 0036-8075 KW - stony meteorites KW - impact features KW - asteroids KW - Vesta Asteroid KW - Rheasilvia Basin KW - parent bodies KW - HED meteorites KW - diogenite KW - Dawn Mission KW - achondrites KW - infrared spectra KW - meteorites KW - mineral composition KW - howardite KW - eucrite KW - impact craters KW - spectra KW - 04:Extraterrestrial geology UR - http://libproxy.lib.unc.edu/login?url=http://search.proquest.com/docview/1026861658?accountid=14244 L2 - http://vb3lk7eb4t.search.serialssolutions.com/?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQ%3Ageorefmodule&rft_val_fmt=info:ofi/fmt:kev:mtx:journal&rft.genre=article&rft.jtitle=Science&rft.atitle=Spectroscopic+characterization+of+mineralogy+and+its+diversity+across+Vesta&rft.au=De+Sanctis%2C+Maria+Cristina%3BAmmannito%2C+E%3BCapria%2C+M+T%3BTosi%2C+F%3BCapaccioni%2C+F%3BZambon%2C+F%3BCarraro%2C+F%3BFonte%2C+S%3BFrigeri%2C+A%3BJaumann%2C+Ralf%3BMagni%2C+G%3BMarchi%2C+Simone%3BMcCord%2C+T+B%3BMcFadden%2C+Lucy+A%3BMcSween%2C+Harry+Y%3BMittlefehldt%2C+David+W%3BNathues%2C+A%3BPalomba%2C+E%3BPieters%2C+Carle+M%3BRaymond%2C+C+A%3BRussell%2C+Christopher+T%3BToplis%2C+M+J%3BTurrini%2C+D&rft.aulast=De+Sanctis&rft.aufirst=Maria&rft.date=2012-05-11&rft.volume=336&rft.issue=6082&rft.spage=697&rft.isbn=&rft.btitle=&rft.title=Science&rft.issn=00368075&rft_id=info:doi/10.1126%2Fscience.1219270 L2 - http://www.sciencemag.org/ LA - English DB - GeoRef N1 - Copyright - GeoRef, Copyright 2012, American Geosciences Institute.

These large basins provide exceptional windows into impact processes at planetary scales. The youngest, Rheasilvia, is 500 kilometers wide and 19 kilometers deep and finds its nearest morphologic analog among large basins on low-gravity icy satellites. Extensive ejecta deposits occur, but impact melt volume is low, exposing an unusual spiral fracture pattern that is likely related to faulting during uplift and convergence of the basin floor. Rheasilvia obliterated half of another 400-kilometer-wide impact basin, Veneneia. Both basins are unexpectedly young, roughly 1 to 2 billion years, and their formation substantially reset Vestan geology and excavated sufficient volumes of older compositionally heterogeneous crustal material to have created the Vestoids and howardite-eucrite-diogenite meteorites.

The Dawn spacecraft extensively imaged Vesta's surface, revealing a collision-dominated history. Results show that Vesta's cratering record has a strong north-south dichotomy. Vesta's northern heavily cratered terrains retain much of their earliest history. The southern hemisphere was reset, however, by two major collisions in more recent times. We estimate that the youngest of these impact structures, about 500 kilometers across, formed about 1 billion years ago, in agreement with estimates of Vesta asteroid family age based on dynamical and collisional constraints, supporting the notion that the Vesta asteroid family was formed during this event.

We sampled nine primary (parent) volatile species (H (sub 2) O, C (sub 2) H (sub 6) , CH (sub 3) OH, H (sub 2) CO, CH (sub 4) , HCN, C (sub 2) H (sub 2) , NH (sub 3) , CO) and two product species (OH* and NH (sub 2) ). We also report upper limits for HDO and CH (sub 3) D. C/2007 N3 (Lulin) displayed an unusual composition when compared to other comets. Based on comets measured to date, CH (sub 4) and C (sub 2) H (sub 6) exhibited "normal" abundances relative to water, CO and HCN were only moderately depleted, C (sub 2) H (sub 2) and H (sub 2) CO were more severely depleted, and CH (sub 3) OH was significantly enriched. Comet C/2007 N3 (Lulin) is another important and unusual addition to the growing population of comets with measured parent volatile compositions, illustrating that these studies have not yet reached the level where new observations simply add another sample to a population with well-established statistics.

The Martian airglow AN - 1093457110; 16898880 AB - One of the objectives of spectrometers onboard space missions is to retrieve atmospheric parameters (notably density, composition and temperature). To fulfill this objective, comparisons between observations and model results are necessary. Knowledge of these model uncertainties is therefore necessary, although usually not considered, to estimate the accuracy in planetary upper atmosphere remote sensing of these parameters. In Part I of this study, "Computing uncertainties in ionosphere-airglow models: I. Electron flux and species production uncertainties for Mars" (Gronoff et al., 2012), we presented the uncertainties in the production of excited states and ionized species from photon and electron impacts, computed with a Monte-Carlo approach, and we applied this technique to the Martian upper atmosphere. In the present paper, we present the results of propagation of these production errors to the main UV emissions and the study of other sources of uncertainties. As an example, we studied several aspects of the model uncertainties in the thermosphere of Mars, and especially the O(1S) green line (557.7 nm, with its equivalent, the trans-auroral line at 297.2 nm), the Cameron bands CO(a3 capital pi ), and CO2+(B2 capital sigma u+) doublet emissions. We first show that the excited species at the origin of these emissions are mainly produced by electron and photon impact. We demonstrate that it is possible to reduce the computation time by decoupling the different sources of uncertainties; moreover, we show that emission uncertainties can be large (>30%) because of the strong sensitivity to the production uncertainties. Our study demonstrates that uncertainty calculations are a crucial step prior to performing remote sensing in the atmosphere of Mars and the other planets and can be used as a guide to subsequent adjustments of cross sections based on aeronomical observations. Finally, we compare the simulations with observations from the SPICAM spectrometer on the Mars Express spacecraft. The production of excited species at the origin of the green line, the CO Cameron bands and the CO2+(B) doublet is found to be on the dayside, consistent with photon and electron impact on CO2 as the main source of excitation of the three emissions, in contrast to the findings of Huestis et al. (2010) for the O(1S) case. Moreover, we re-examine the cross section for the production of the Cameron bands by electron impact on CO2. JF - Journal of Geophysical Research.

Basaltic breccias produced by the impact form the rim deposits, with stratigraphy similar to that observed at similar-sized craters on Earth. Highly localized zinc enrichments in some breccia materials suggest hydrothermal alteration of rim deposits. Gypsum-rich veins cut sedimentary rocks adjacent to the crater rim. The gypsum was precipitated from low-temperature aqueous fluids flowing upward from the ancient materials of the rim, leading temporarily to potentially habitable conditions and providing some of the waters involved in formation of the ubiquitous sulfate-rich sandstones of the Meridiani region.

Eleven subjects (men/women 4/7, age 31.4+ or -12.8 y, weight 68.9+ or -13.2 kg, mean+ or -SD) performed 3 sets of supine left LP to fatigue with 90 s of rest in 4 conditions: HL (%1- RM/cuff pressure: 80%/0); LL (20%/0); LBFR sub(DBP) (20%/1.3 x diastolic blood pressure, BP); LBFR sub(SBP) (20%/1.3 x supine systolic BP). The cuff remained inflated throughout the LBFR exercise sessions. Artery diameter did not change from baseline. BF increased (p LL (9.92+ or -0.82 cm super(3)) > LBFR sub(DBP) (6.47+ or -0.79 cm super(3)) > LBFR sub(SBP) (3.51+ or -0.59 cm super(3)). Blunted exercise induced increases occurred in HR, SV, and CO after LBFR compared to HL and LL. HR increased 45% after HL and LL and 28% after LBFR (p<0.05), but SV increased (p<0.05) only after HL.

That is, explosive active regions are concentrated in a main-sequence path bordering the free-energy-limit line in (flux content, free-energy proxy) phase space. Here, we present evidence that specifies the underlying magnetic condition that gives rise to the free-energy limit and the accompanying main sequence of explosive active regions. Using a suitable free-energy proxy measured from vector magnetograms of 44 active regions, we find evidence that (1) in active regions at and near their free-energy limit, the ratio of magnetic-shear free energy to the non-free magnetic energy the potential field would have is of the order of one in the core field, the field rooted along the neutral line, and (2) this ratio is progressively less in active regions progressively farther below their free-energy limit. Evidently, most active regions in which this core-field energy ratio is much less than one cannot be triggered to explode; as this ratio approaches one, most active regions become capable of exploding; and when this ratio is one, most active regions are compelled to explode.

Accurate measurement of volatiles in the solar system is therefore important for understanding not only the nebular hypothesis and origin of life but also planetary cosmogony as a whole. In this work, we propose a new remote sensing technique to infer the outer planets' water content by measuring Tremendously and Extremely Low Frequency (TLF-ELF) electromagnetic wave characteristics (Schumann resonances) excited by lightning in their gaseous envelopes. Schumann resonance detection can be potentially used for constraining the uncertainty of volatiles of the giant planets, mainly Uranus and Neptune, because such TLF-ELF wave signatures are closely related to the electric conductivity profile and water content.

Mapping of young lava flow fields is providing evidence that the basic hydraulic, thermal, and structural events during the emplacement of lava flows is surprisingly complex, yet the events can be unraveled. Our work shows that the distribution of magma partials during the lifetime of an eruption and during the corresponding flow field development may be determined. Mapping of the McCartys lava flow, El Malpais, New Mexico, focused on the time-transgressive thermal and mechanical details of emplacement, preserved in the physical details of its surface and interior, is yielding new information on the sequence of emplacement events in large flow-fields. This mapping is being compared with the results of similar mapping on historic lava flows and actively inflating lava flows in Hawai'i. One of the largest sources of complexity is a result of lava inflation, a platform-sheet flow characteristic of large flows that is strongly influenced by the balance of lava margin strength and lava hydrostatic head. Stress in excess of the critical yield strength necessary for breakouts and advance may be governed largely by regional slope or, on low angle slopes, the timing of excess pressure from local inflation. Both the McCartys and 1859 Hawai'i lava flows are extensive sheeted pahoehoe surfaces with micro-spiny surface textures and deformed "skins" of variable thickness (from millimeters to meters). Central platy pahoehoe-bearing platforms with V-shaped pits and marginal clefts are commonly elevated from one to over 10 meters above surrounding pahoehoe sheet lobes. These sheet lobe surfaces were subjected to differential surface stresses causing immediate plastic and subsequent brittle shear, compressional, and extensional deformation zones defined now by thin platy rubble zones. Based on timing estimated from thickness of deformed pahoehoe crusts, the lavas of these platforms were emplaced and deformed in less than a few hours. Subsequent deformation of the margins, squeeze ups in deep clefts, and marginal tilting and apparent elevation of the platforms occurred as late as several weeks after the sheet lobe.

Twelve Ti-S phase grains were identified in a rare barred olivine (BO) chondrule; three of the grains were extracted by the focused ion beam technique. Because of the submicrometer size of the wassonite grains, it was not possible to determine conventional macroscopic properties. However, the chemical composition and crystal structure were well constrained by extensive quantitative energy-dispersive X-ray analysis and electron diffraction using transmission electron microscopy (TEM). The crystal system for wassonite is rhombohedral (a=3.42+ or -0.07, c=26.50+ or -0.53 Aa) with space group: R3m, cell volume: 268.4+ or -0.53 Aa (super 3) , Z=9, density (calculated): 4.452 g/cm (super 3) , empirical formula: (Ti (sub 0.93) ,Fe (sub 0.06) ,Cr (sub 0.01) )S. The wassonite grains crystallized from the chondrule melt that was itself formed in the solar nebula, not on the parent asteroid. The other crystalline phases in the BO chondrule include forsterite, enstatite, troilite, metallic Fe-Ni, and osbornite (as well as the new Ti-S-bearing minerals and schollhornite) are highly reduced and indicate formation at low-oxygen fugacities.

The satellite rain products are derived from the TRMM Microwave Imager (TMI), precipitation radar (PR), and combined (COM) rain algorithms using observations from both instruments. The TRMM satellite and GV rain products are spatiotemporally matched and are intercompared at multiple time scales over the 12-yr period from 1998 to 2009. On monthly and yearly scales, the TG agree excellently with the GR because the GR rain rates are generated using the TG data as a constraint on a monthly basis. However, large disagreements exist between the GR and TG at shorter time scales because of their significantly different spatial and temporal sampling modes. The yearly biases relative to the GR for the PR and TMI are generally negative, with a few exceptions. The COM bias fluctuates from year to year over the 12-yr period. The PR, TMI, and COM are in good overall agreement with the GR in the lower range of rain rates, but the agreement is notably worse at higher rain rates. The diurnal cycle of rainfall is captured well by all products, but the peak satellite-derived rainfall (PR, TMI, and COM) lags the peak from the ground measurements (GR and TG) by ~1 h.

Predictions from such LES are grid-spacing dependent since any subgrid-scale (SGS) model used in the LES equations is dependent on the resolved flow field which itself varies with grid spacing. Moreover, numerical errors affect the flow field, especially the smallest resolved scales. Thus, predictions using this approach are affected by both modelling and numerical choices. However, grid-spacing-independent LES predictions unaffected by numerical choices are necessary to validate LES models through comparison with a trusted template. First, such a template is created here through direct numerical simulation (DNS). Then, simulations are conducted using the conventional LES equations and also LES equations which are here reformulated so that the small-scale-producing nonlinear terms in these equations are explicitly filtered (EF) to remove scales smaller than a fixed filter width; this formulation is called EFLES. First, LES is conducted with four SGS models, then EFLES is performed with two of the SGS models used in LES; the results from all these simulations are compared to those from DNS and from the filtered DNS (FDNS). The conventional LES solution is both grid-spacing and spatial discretization-order dependent, thus showing that both of these numerical aspects affect the flow prediction. The solution from the EFLES equations is grid independent for a high-order spatial discretization on all meshes tested. However, low-order discretizations require a finer mesh to reach grid independence. With an eighth-order discretization, a filter-width to grid-spacing ratio of two is sufficient to reach grid independence, while a filter-width to grid-spacing ratio of four is needed to reach grid independence when a fourth- or a sixth-order discretization is employed. On a grid fine enough to be utilized in a DNS, the EFLES solution exhibits grid independence and does not converge to the DNS solution. The velocity-fluctuation spectra of EFLES follow those of FDNS independent of the grid spacing used, in concert with the original concept of LES. The reasons for the different predictions of conventional LES or EFLES according to the SGS model used, and the different characteristics of the EFLES predictions compared to those from conventional LES are analysed.

The new formulation is physically-based and explicitly accounts for the dependency of the ice crystal concentration on temperature, supersaturation, cooling rate, and particle size, surface area and composition. This is achieved by introducing the concepts of ice nucleation coefficient (the number of ice germs present in a particle) and nucleation probability dispersion function (the distribution of ice nucleation coefficients within the aerosol population). The new formulation is used to generate ice nucleation parameterizations for the homogeneous freezing of cloud droplets and the heterogeneous deposition ice nucleation on dust and soot ice nuclei. For homogeneous freezing, it was found that by increasing the dispersion in the droplet volume distribution the fraction of supercooled droplets in the population increases. For heterogeneous ice nucleation the new formulation consistently describes singular and stochastic behavior within a single framework. Using a fundamentally stochastic approach, both cooling rate independence and constancy of the ice nucleation fraction over time, features typically associated with singular behavior, were reproduced. Analysis of the temporal dependency of the ice nucleation spectrum suggested that experimental methods that measure the ice nucleation fraction over few seconds would tend to underestimate the ice nuclei concentration. It is shown that inferring the aerosol heterogeneous ice nucleation properties from measurements of the onset supersaturation and temperature may carry significant error as the variability in ice nucleation properties within the aerosol population is not accounted for. This work provides a simple and rigorous ice nucleation framework where theoretical predictions, laboratory measurements and field campaign data can be reconciled, and that is suitable for application in atmospheric modeling studies.

In this paper, we examine the clues available from isotopic ratios ( super(12)C/ super(13)C and D/H) in Titan's methane as to the past atmosphere history of this species. We first analyze recent infrared spectra of CH sub(4) collected by the Cassini Composite Infrared Spectrometer, measuring simultaneously for the first time the abundances of all three detected minor isotopologues: super(13)CH sub(4), super(12)CH sub(3)D, and super(13)CH sub(3)D. From these we compute estimates of super(12)C/ super(13)C = 86.5 + or - 8.2 and D/H = (1.59 + or - 0.33) x 10 super(-4), in agreement with recent results from the Huygens GCMS and Cassini INMS instruments. We also use the transition state theory to estimate the fractionation that occurs in carbon and hydrogen during a critical reaction that plays a key role in the chemical depletion of Titan's methane: CH sub(4) + C sub(2)H arrow right CH sub(3) + C sub(2)H sub(2). Using these new measurements and predictions we proceed to model the time evolution of super(12)C/ super(13)C and D/H in Titan's methane under several prototypical replenishment scenarios. In our Model 1 (no resupply of CH sub(4)), we find that the present-day super(12)C/ super(13)C implies that the CH sub(4) entered the atmosphere 60-1600 Myr ago if methane is depleted by chemistry and photolysis alone, but much more recently-most likely less than 10 Myr ago-if hydrodynamic escape is also occurring. On the other hand, if methane has been continuously supplied at the replenishment rate then the isotopic ratios provide no constraints, and likewise for the case where atmospheric methane is increasing. We conclude by discussing how these findings may be combined with other evidence to constrain the overall history of the atmospheric methane.

Although viable, this model does not include the effect of a giant planet that might have existed or been growing in the outer regions. We present the results of a concept study where we have examined the effect of a planetary body in the orbit of Jupiter on the early scattering of planetesimals from the terrestrial region into the asteroid belt. We integrated the orbits of a large battery of planetesimals in a disk of planetary embryos and studied their evolutions for different values of the mass of the planet. Results indicate that when the mass of the planet is smaller than 10 M (sub earth) , its effects on the interactions among planetesimals and planetary embryos are negligible. However, when the planet mass is between 10 and 50 M (sub earth) , simulations point to a transitional regime with approximately 50 M (sub earth) being the value for which the perturbing effect of the planet can no longer be ignored. Simulations also show that further increase of the mass of the planet strongly reduces the efficiency of the scattering of planetesimals from the terrestrial planet region into the asteroid belt. We present the results of our simulations and discuss their possible implications for the time of giant planet formation. Copyright (Copyright) 2012. The American Astronomical Society.

The impact is first assessed globally on a sample of more than forty forecasts per experiment, through the standard 500 hPa anomaly correlation metrics. Next, the focus is on precipitation analysis and precipitation forecast skill relative to one particular event: an extreme rainfall episode which occurred in late July 2010 in Pakistan, causing massive floods along the Indus River Valley. Results show that, in addition to improving the global forecast skill, the assimilation of quality-controlled AIRS temperature retrievals obtained under partly cloudy conditions produce better precipitation analyses, and substantially better 7-day forecasts, than assimilation of clear-sky radiances. The improvement of precipitation forecast skill up to 7 days is very significant in the tropics, and is caused by an improved representation, attributed to cloudy retrieval assimilation, of two contributing mechanisms: the low-level moisture advection, and the concentration of moisture over the area in the days preceding the precipitation peak.

DO - http://dx.doi.org/10.1029/2011JD017093 ER - TY - JOUR T1 - Impact of aerosols on convective clouds and precipitation AN - 1014104047; 16625471 AB - Aerosols are a critical factor in the atmospheric hydrological cycle and radiation budget. As a major agent for clouds to form and a significant attenuator of solar radiation, aerosols affect climate in several ways. Current research suggests that aerosol effects on clouds could further extend to precipitation, both through the formation of cloud particles and by exerting persistent radiative forcing on the climate system that disturbs dynamics. However, the various mechanisms behind these effects, in particular, the ones connected to precipitation, are not yet well understood. The atmospheric and climate communities have long been working to gain a better grasp of these critical effects and hence to reduce the significant uncertainties in climate prediction resulting from such a lack of adequate knowledge. Here we review past efforts and summarize our current understanding of the effect of aerosols on convective precipitation processes from theoretical analysis of microphysics, observational evidence, and a range of numerical model simulations. In addition, the discrepancies between results simulated by models, as well as those between simulations and observations, are presented. Specifically, this paper addresses the following topics: (1) fundamental theories of aerosol effects on microphysics and precipitation processes, (2) observational evidence of the effect of aerosols on precipitation processes, (3) signatures of the aerosol impact on precipitation from large-scale analyses, (4) results from cloud-resolving model simulations, and (5) results from large-scale numerical model simulations. Finally, several future research directions for gaining a better understanding of aerosol-cloud-precipitation interactions are suggested.

Siderophile element patterns in aubrites are either similar to those in metal from enstatite chondrites, or can be derived by crystallization from metallic liquids derived by partial melting of E chondrites. Some metal grains in Mt. Egerton, Cumberland Falls, and Aubres show moderate to severe depletion in compatible highly siderophile elements (Re, Os, Ir, Ru) which are consistent with solid metal/liquid metal differentiation of enstatite chondrite-like metal. Metals from chondrite inclusions in Cumberland Falls show more extremely fractionated patterns than those from the aubritic matrix, potentially hinting at fractionation and partial melting processes affecting not only the aubrite parent body, but the chondrite body from which the inclusions were derived as well. Models using experimental partition coefficients show that aubrite metal chemically corresponds to solid metal segregated during differentiation of primary metallic liquids of EH/EL composition that contained both substantial S- and C-contents. This result is consistent with a genetic link between enstatite chondrites and aubrites, but as to whether aubrites were derived from the same body(ies) as enstatite chondrites, or have their origin in multiple, and potentially separated bodies, cannot be answered unequivocally with chemical or isotopic data alone.

The dynamic range of elevations is considerably smaller than those of Mars or the Moon. The most prominent feature is an extensive lowland at high northern latitudes that hosts the volcanic northern plains. Within this lowland is a broad topographic rise that experienced uplift after plains emplacement. The interior of the 1500-km-diameter Caloris impact basin has been modified so that part of the basin floor now stands higher than the rim. The elevated portion of the floor of Caloris appears to be part of a quasi-linear rise that extends for approximately half the planetary circumference at mid-latitudes. Collectively, these features imply that long-wavelength changes to Mercury's topography occurred after the earliest phases of the planet's geological history.

In the northern hemisphere, several large gravity anomalies, including candidate mass concentrations (mascons), exceed 100 milli-Galileos (mgal). Mercury's northern hemisphere crust is thicker at low latitudes and thinner in the polar region and shows evidence for thinning beneath some impact basins. The low-degree gravity field, combined with planetary spin parameters, yields the moment of inertia C/MR (super 2) = 0.353 + or - 0.017, where M and R are Mercury's mass and radius, and a ratio of the moment of inertia of Mercury's solid outer shell to that of the planet of C (sub m) /C = 0.452 + or - 0.035. A model for Mercury's radial density distribution consistent with these results includes a solid silicate crust and mantle overlying a solid iron-sulfide layer and an iron-rich liquid outer core and perhaps a solid inner core.

N1 - Last updated - 2012-04-13 ER - TY - JOUR T1 - Direct numerical simulation of stationary homogeneous stratified sheared turbulence AN - 1315606628; 17590240 AB - Using direct numerical simulation, we investigate stationary and homogeneous shear-driven turbulence in various stratifications, ranging from neutral to very stable. To attain and maintain a stationary flow, we throttle the mean shear so that the net production stays constant for all times. This results in a flow that is characterized solely by its mean shear and its mean buoyancy gradient, independent of initial conditions. The method of throttling is validated by comparison with experimental spectra in the case of neutral stratification. With increasing stratification comes the emergence of vertically sheared large-scale horizontal motions that preclude a straightforward interpretation of flow statistics. However, once these motions are excluded, simply by subtracting the horizontal average, the underlying flow appears amenable to the standard methods of turbulence analysis. It is shown that a direct acknowledgement of the confining influence of the periodic simulation box can lead to a meaningful physical interpretation of the large scales. Once an appropriate confinement scale is identified, many features, including horizontal spectra, flux-gradient relationships and length scales, of stratified sheared turbulence can be readily understood, both qualitatively and quantitatively, in terms of Monin-Obukhov similarity theory. Finally, the similarity-theory framework is used to interpret the scaling of the vertical diapycnal diffusivity in stratified turbulence.

This is true because the physical processes involved are complex, but, in contrast to terrestrial weather, the supporting observations are typically sparse. Models play a vital role in establishing a physically meaningful context for interpreting limited observations, testing theory, and producing both nowcasts and forecasts. For example, with accurate forecasting of hazardous space weather conditions, spacecraft operators can place sensitive systems in safe modes, and power utilities can protect critical network components from damage caused by large currents induced in transmission lines by geomagnetic storms.

N1 - Last updated - 2012-04-09 ER - TY - JOUR T1 - Air density 2.7 billion years ago limited to less than twice modern levels by fossil raindrop imprints AN - 1434031944; 18463629 AB - According to the 'Faint Young Sun' paradox, during the late Archaean eon a Sun approximately 20% dimmer warmed the early Earth such that it had liquid water and a clement climate. Explanations for this phenomenon have invoked a denser atmosphere that provided warmth by nitrogen pressure broadening or enhanced greenhouse gas concentrations. Such solutions are allowed by geochemical studies and numerical investigations that place approximate concentration limits on Archaean atmospheric gases, including methane, carbon dioxide and oxygen. But no field data constraining ground-level air density and barometric pressure have been reported, leaving the plausibility of these various hypotheses in doubt. Here we show that raindrop imprints in tuffs of the Ventersdorp Supergroup, South Africa, constrain surface air density 2.7 billion years ago to less than twice modern levels. We interpret the raindrop fossils using experiments in which water droplets of known size fall at terminal velocity into fresh and weathered volcanic ash, thus defining a relationship between imprint size and raindrop impact momentum. Fragmentation following raindrop flattening limits raindrop size to a maximum value independent of air density, whereas raindrop terminal velocity varies as the inverse of the square root of air density. If the Archaean raindrops reached the modern maximum measured size, air density must have been less than 2.3kgm super(-3), compared to today's 1.2kgm super(-3), but because such drops rarely occur, air density was more probably below 1.3kgm super(-3). The upper estimate for air density renders the pressure broadening explanation possible, but it is improbable under the likely lower estimates. Our results also disallow the extreme CO sub(2) levels required for hot Archaean climates.

Searches for infrared (IR) spectral features of solid-phase acetylene are under way, but few laboratory reference spectra of C (sub 2) H (sub 2) in icy mixtures, which are needed for spectral fits to observational data, have been published. Here, we report a systematic study of the IR spectra of condensed-phase pure acetylene and acetylene in ices dominated by carbon monoxide (CO), carbon dioxide (CO (sub 2) ), methane (CH (sub 4) ), and water (H (sub 2) O). We present new spectral data for these ices, including band positions and intrinsic band strengths. For each ice mixture and concentration, we also explore the dependence of acetylene's V (sub 5) -band position (743 cm (super -1) , 13.46 mu m) and FWHM on temperature. Our results show that the V (sub 5) feature is much more cleanly resolved in ices dominated by non-polar and low-polarity molecules, specifically CO, CO (sub 2) , and CH (sub 4) , than in mixtures dominated by H (sub 2) O-ice.

This landmark decision represented the culmination of a 10-year strategic plan by the United States that was as much unconventional as it was methodical. Today, all the world's major space-faring nations and organizations recognize the need to control the creation of man-made debris in Earth orbit to protect the space environment for future generations.

He emphasized particularly that what fuels the debate on climate change is, largely, the degree of uncertainty inherent in the consequences to be anticipated from observation of the facts, not the description of the facts itself. In his view, the main aim of climate sceptics is to block the political measures for combating climate change. However, since they do not admit to this political posture, they choose instead to deny the scientific reality. This month, Futuribles complements this socio-psychological analysis of climate-sceptical discourse with an -- in this case, wholly scientific -- analysis of what we know (or do not know) about climate change on our planet. Pierre Morel gives a detailed account of the state of our knowledge in the climate field and what we are able to predict in the medium/long-term. After reminding us of the influence of atmospheric meteorological processes on the climate, he specifies the extent of global warming observed since 1850 and the main origin of that warming, as revealed by the current state of knowledge: the increase in the concentration of greenhouse gases. He then describes the changes in meteorological regimes (showing also the limits of climate simulation models), the modifications of hydrological regimes, and also the prospects for rises in sea levels. He also specifies the mechanisms that may potentially amplify all these phenomena and the climate disasters that might ensue. Lastly, he shows what are the scientific data that cannot be disregarded, the consequences of which are now inescapable (melting of the ice-caps, rises in sea level etc.), the only remaining uncertainty in this connection being the date at which these things will happen. "In this perspective," Morel concludes, "the continuation of our model of civilization comes at the cost of a fundamental revision of the current paradigm of economic and demographic growth.".

The microwave data were acquired over a natural Virginia Pine forest in Maryland by a ground-based microwave active/passive instrument system in 2008/2009. Ground measurements of the tree biophysical parameters and forest floor characteristics were obtained during the field campaign. The test site consisted of medium-sized evergreen conifers with an average height of 12 m and average diameters at breast height of 12.6 cm. The site is a typical pine forest site in that there is a surface layer of loose debris/needles and an organic transition layer above the mineral soil. In an effort to characterize and model the impact of the surface litter layer, an experiment was conducted on a day with wet soil conditions, which involved removal of the surface litter layer from one half of the test site while keeping the other half undisturbed. The observations showed detectable decrease in emissivity for both polarizations after the surface litter layer was removed. A first-order radiative transfer model of the forest stands including the multilayer nature of the forest floor in conjunction with the ground truth data are used to compute forest emission. The model calculations reproduced the major features of the experimental data over the entire duration, which included the effects of surface litter and ground moisture content on overall emission. Both theory and experimental results confirm that the litter layer increases the observed canopy brightness temperature and obscure the soil emission.

However, the taxonomy of H sub(2)-producing microorganisms (hydrogenogens) in these mats has not been previously determined. With combined biogeochemical and molecular studies of microbial mats collected from Elkhorn Slough, Monterey Bay, California, we characterized the mechanisms of H sub(2) production and identified a dominant hydrogenogen. Net production of H sub(2) was observed within the upper photosynthetic layer (0-2 mm) of the mats under dark and anoxic conditions. Pyrosequencing of rRNA gene libraries generated from this layer demonstrated the presence of 64 phyla, with Bacteriodetes, Cyanobacteria and Proteobacteria dominating the sequences. Sequencing of rRNA transcripts obtained from this layer demonstrated that Cyanobacteria dominated rRNA transcript pyrotag libraries. An OTU affiliated to Microcoleus spp. was the most abundant OTU in both rRNA gene and transcript libraries. Depriving mats of sunlight resulted in an order of magnitude decrease in subsequent nighttime H sub(2) production, suggesting that newly fixed carbon is critical to H sub(2) production. Suppression of nitrogen (N sub(2))-fixation in the mats did not suppress H sub(2) production, which indicates that co-metabolic production of H sub(2) during N sub(2)-fixation is not an important contributor to H sub(2) production. Concomitant production of organic acids is consistent with fermentation of recently produced photosynthate as the dominant mode of H sub(2) production. Analysis of rRNA % transcript:% gene ratios and H sub(2)-evolving bidirectional [NiFe] hydrogenase % transcript:% gene ratios indicated that Microcoelus spp. are dominant hydrogenogens in the Elkhorn Slough mats.

Our model of the Mf ocean tide assimilates more than 14 years of altimeter data from the Topex/Poseidon and Jason-1 satellites. Because the Mf altimetric signal-to-noise ratio is very small, it is critical that altimeter data not be overweighted. The polar motion data, plus tide-gauge data and independent altimeter data, give useful additional information, with only the polar motion putting constraints on tidal current velocities. The resulting ocean-tide model, plus the dominant elastic body tide, leaves a small residual in observed LOD caused by mantle anelasticity. The inferred effective tidal Q of the anelastic body tide is 90 and is in line with a omega (super alpha ) frequency dependence with alpha in the range 0.2-0.3. Abstract Copyright (2012), RAS.

The definitive diagnosis requires the stimulation of coronary vasospasm using provocative agents, which can be life threatening. We present a case where localized stenosis of proximal left anterior descending artery was observed on the coronary angiography, which disappeared on subsequent views, and hence, coronary stenting was deferred and patient responded well to medical management alone.

The coarse-grained architecture of cellular replication and production and implicit cellular regulation mechanisms used in this model make it straightforward to incorporate various radiation conditions. Model simulations with reported absorbed doses as inputs are shown to qualitatively and quantitatively describe a wide range of accidental data in vastly different scenarios. In addition, the absolute lymphocyte counts and the depletion rate constants calculated by this model show good correlation with two widely recognized empirical methods for early dose assessment. This demonstrates the potential to use the biophysical model as an alternative method for the assessment of radiation injury in the case of large-scale radiation disaster. The physiological assumptions underlying the model are also discussed, which may provide a putative mechanism for some biodosimetric tools that use the peripheral blood cell counts as markers of radiation impairment.

It has been proposed that microorganisms, especially anaerobic microorganisms, can overcome kinetic barriers to facilitate dolomite precipitation, although their specific role in dolomite formation is still unclear. Our experimental results demonstrate that disordered dolomite can be synthesized at room temperature abiotically from solutions containing polysaccharides such as carboxymethyl cellulose or agar. We propose that when dissolved in solution, polysaccharides can be strongly adsorbed on Ca-Mg carbonate surfaces through hydrogen bonding. The adsorbed polysaccharides may help weaken the chemical bonding between surface Mg (super 2+) ions and water molecules, which can lower the energy barrier to the desolvation of surface Mg (super 2+) -water complexes, enhance Mg (super 2+) incorporation into the precipitating carbonate, and thereby promote disordered dolomite formation. In natural environments, it is possible that polysaccharides produced by microorganisms, e.g., extracellular polysaccharides, may play a key role in promoting disordered dolomite nucleation and crystallization. In marine sediments, the accumulated dissolved carbohydrates produced from organic matter degradation during early diagenesis may also serve as catalysts for disordered dolomite formation.

Based on data collected in January 2007, we investigate the most useful criteria for screening the MODIS and CALIOP retrievals to achieve the best agreement between the two data sets. Applying these criteria to eight months of data (Jan, Apr, Jul, Oct 2007 and 2009), we find an order of magnitude increase for the CALIOP V3 data density (by comparison to V2), that is generally accompanied by equal or better agreement with MODIS AOD. Differences in global, monthly mean, over-ocean AOD (532 nm) between CALIOP and MODIS range between 0.03 and 0.04 for CALIOP V3, with CALIOP generally biased low, when all available data from both sensors are considered. Root-mean-squares (RMS) differences in instantaneously collocated AOD retrievals by the two instruments are reduced from values ranging between 0.14 and 0.19 using the unscreened V3 data to values ranging from 0.09 to 0.1 for the screened data. A restriction to scenes with cloud fractions less than 1% (as defined in the MODIS aerosol retrievals) generally results in improved correlation (R super(2)>0.5), except for the month of July when correlations remain relatively lower. Regional assessments show hot spots in disagreement between the two sensors in Asian outflow during April and off the coast of South Africa in July.

RAQMS is a global scale meteorological and chemical modeling system. Results from these simulations, averaged over April 2008, indicate that tropospheric ozone column increases by more than 10 Dobson units (DU) near the Thailand region, and by lesser amounts in the other regions due to the fires. Widespread increases in the optical depths of organic and black carbon aerosols are also noted. We have used an off-line radiative transfer model to evaluate the direct radiative forcing due to the fire-induced changes in atmospheric composition. For clear sky, the monthly averaged radiative forcing at the top of the atmosphere (TOA) is mostly negative with peak values less than -12 W/m2 occurring near the fire regions. The negative forcing represents the increased outgoing shortwave radiation caused by scattering due to carbonaceous aerosols. At high latitudes, the radiative forcing is positive due to the presence of absorbing aerosols over regions of high surface albedo. Regions of positive forcing at TOA are more pronounced under total sky conditions. The monthly averaged radiative forcing at the surface is mostly negative, and peak values of less than -30 W/m2 occur near the fire regions. Persistently large negative forcing at the surface could alter the surface energy budget and potentially weaken the hydrological cycle. JF - Journal of Geophysical Research.

The propagator depends only on the mean flow and an adjoint vector Green's function for a particular form of the linearized Euler equations. Recent numerical calculations of Karabasov, Bogey & Hynes (AIAA Paper 2011-2929) for a Mach 0.9 jet show use of the true non-parallel flow Green's function rather than the more conventional locally parallel flow result leads to a significant increase in the predicted low-frequency sound radiation at observation angles close to the downstream jet axis. But the non-parallel flow appears to have little effect on the sound radiated at 90 degree to the downstream axis. The present paper is concerned with the effects of non-parallel mean flows on the adjoint vector Green's function. We obtain a low-frequency asymptotic solution for that function by solving a very simple second-order hyperbolic equation for a composite dependent variable (which is directly proportional to a pressure-like component of this Green's function and roughly corresponds to the strength of a monopole source within the jet). Our numerical calculations show that this quantity remains fairly close to the corresponding parallel flow result at low Mach numbers and that, as expected, it converges to that result when an appropriately scaled frequency parameter is increased. But the convergence occurs at progressively higher frequencies as the Mach number increases and the supersonic solution never actually converges to the parallel flow result in the vicinity of a critical- layer singularity that occurs in that solution. The dominant contribution to the propagator comes from the radial derivative of a certain component of the adjoint vector Green's function. The non-parallel flow has a large effect on this quantity, causing it (and, therefore, the radiated sound) to increase at subsonic speeds and decrease at supersonic speeds. The effects of acoustic source location can be visualized by plotting the magnitude of this quantity, as function of position. These 'altitude plots' (which represent the intensity of the radiated sound as a function of source location) show that while the parallel flow solutions exhibit a single peak at subsonic speeds (when the source point is centred on the initial shear layer), the non-parallel solutions exhibit a double peak structure, with the second peak occurring about two potential core lengths downstream of the nozzle. These results are qualitatively consistent with the numerical calculations reported in Karabasov et al. (2011).

Observational evidence of gravity-wave activity is provided by Atmospheric Infrared Sounder (AIRS) radiances and infrared spectroscopic detection of nitric acid trihydrate (NAT) in PSCs is obtained from the Michelson Interferometer for Passive Atmospheric Sounding (MIPAS). Goddard Earth Observing System Data Assimilation System (GEOS-5 DAS) analyses are used to derive Lagrangian trajectories and to determine temperature-time histories of air parcels. We use CALIOP backscatter and depolarization measurements to classify PSCs and the MLS measurements to determine the corresponding gas-phase HNO sub(3) as a function of temperature. For liquid PSCs the uptake of HNO sub(3) follows the theoretical equilibrium curve for supercooled ternary solutions (STS), but at temperatures about 1 K lower as determined from GEOS-5. In the presence of solid phase PSCs, above the ice frost-point, the HNO sub(3) depletion occurs over a wider range of temperatures (+2 to -7 K) distributed about the NAT equilibrium curve. Rapid gas-phase HNO sub(3) depletion is first seen by MLS from from 23-25 May 2008, consisting of a decrease in the volume mixing ratio from 14 ppbv (parts per billion by volume) to 7 ppbv on the 46-32 hPa (hectopascal) pressure levels and accompanied by a 2-3 ppbv increase by renitrification at the 68 hPa pressure level. The observed region of depleted HNO sub(3) is substantially smaller than the region bounded by the NAT existence temperature threshold. Temperature-time histories of air parcels demonstrate that the depletion is more clearly correlated with prior exposure to temperatures a few kelvin above the frost-point. From the combined data we infer the presence of large-size NAT particles with effective radii >5-7 mu m and low NAT number densities 0.2 cm super(-3).

N1 - Last updated - 2012-03-15 ER - TY - JOUR T1 - Cloud ice water content retrieved from the CALIOP space-based lidar AN - 1014105748; 16644828 AB - Ice water content (IWC) profiles are derived from retrievals of optical extinction from the Cloud-Aerosol Lidar with Orthogonal Polarization (CALIOP) satellite lidar, using a parameterization derived from particle probe measurements acquired during several aircraft field campaigns. With more than five years of data now available, CALIOP IWC is well suited for characterization of the climate-sensitive upper troposphere/lower stratosphere where reliable global IWC measurements are needed to reduce climate model uncertainty. We describe CALIOP IWC and compare it with global satellite-based and regional airborne IWC measurements made during August 2007. IWC distributions in a convective cloud sampled during the Tropical Clouds, Chemistry, Composition and Climate experiment show temperature-dependent differences between in situ measured IWC, IWC retrieved from CloudSat and CALIOP, and IWC parameterized from the airborne Cloud Physics Lidar (CPL) 532 nm volume extinction coefficients. At temperatures above ?50 degree C the CALIOP IWC retrieval indicates less cloud ice than the other instruments, due to signal attenuation and screening for horizontally-oriented ice crystals. Above 12 km where temperatures drop below ?50 degree C CALIOP compares well with in situ IWC measurements. In situ measurements are limited above 12 km, and more cold-temperature comparisons are needed. Global zonal in-cloud IWC averages at altitudes above 9 km show that CloudSat IWC is roughly an order of magnitude higher than CALIOP IWC, consistent with a higher detection threshold. When averaged to the vertical resolution characteristic of Microwave Limb Sounder (MLS), global zonal averages of CALIOP and MLS IWC were found to agree to about +/?50%.

The spectra show clear evidence for warm, water- and carbon-rich dust at approximately 3 AU from the central star, in the system's terrestrial habitability zone. Spectral features due to ultra-primitive cometary material were found, in addition to features due to impact produced silica and high-temperature carbonaceous phases. At least 9 X 1018 kg of 0.1-100 mu m warm dust is present in a collisional equilibrium distribution with dn/da approximately a (super -3.5) , the equivalent of a 130 km radius Kuiper Belt object (KBO) of 1.0 g cm (super 3) density and similar to recent estimates of the mass delivered to the Earth at 0.6-0.8 Gyr during the late-heavy bombardment. We conclude that the parent body was a Kuiper Belt body or bodies which captured a large amount of early primitive material in the first megayears of the system's lifetime and preserved it in deep freeze at approximately 150 AU. At approximately 1.4 Gyr they were prompted by dynamical stirring of their parent Kuiper Belt into spiraling into the inner system, eventually colliding at 5-10 km s (super -1) with a rocky planetary body of mass 0.1% of < or =M (sub Earth's Oceans) ) and carbon-rich material. The Spitzer spectrum also closely matches spectra reported for the Ureilite meteorites of the Sudan Almahata Sitta fall in 2008, suggesting that one of the Ureilite parent bodies was a KBO.

N1 - Last updated - 2012-03-01 ER - TY - JOUR T1 - Large-scale simulations for turbine engine core noise AN - 1718951670; 16506894 AB - As turbofan engine bypass ratios continue to increase, the contribution of the turbine to the engine and aircraft noise signature is receiving more attention. Understanding the relative importance of the various turbine noise generation mechanisms and the characteristics of the turbine acoustic transmission loss are essential ingredients in developing robust reduced-order models for predicting the turbine noise signature. A computationally based investigation has been undertaken to help guide the development of a turbine noise prediction capability that does not rely on empiricism. Under the auspices of the Fundamental Aeronautics Program, NASA is currently funding core noise research focused on the generation and propagation mechanisms of combustor and turbine noise in the combustor-turbine-nozzle system. Highly detailed numerical simulations of the unsteady flow field inside the first stage of a modern high-pressure turbine were carried out using TURBO. Spectral and modal analysis of the unsteady pressure data from the numerical simulation of the turbine stage show a circumferential modal distribution that is consistent with the Tyler-Sofrin rule, which gives confidence in the approach. Additionally, initial steps have been taken in determining the source strength hierarchy.

AN - 1348489128; 17906287 AB - INTRODUCTION: The National Aeronautics and Space Administration (NASA) is currently considering plans for the human exploration of a Near Earth Asteroid (NEA). Reasons for undertaking the human exploration of a NEA include increasing the scientific understanding of the origins of our solar system, and developing technology for the exploration of more distant destinations such as Mars. Most mission scenarios have a duration on the order of several months or a year, most of which is spent in transit to and from the NEA. The choice of a particular NEA destination determines the mission duration and guides the types of exploration activities that can be performed on and near the NEA. NASA's Human Research Program (HRP) has identified short and long-term health risks associated with such missions and begun characterizing the level of risk. Some risk drivers are well known from missions to low Earth orbit and the Moon (e.g., the limited mass, volume, and power available for the medical care system). Other factors emerge as major drivers for NEA missions. Some are fundamental characteristics of the mission parameters (e.g., mission duration, distance) and others are strongly dependent on the specifics of how the mission is implemented (e.g., isolation and confinement). Careful consideration of these factors will be required for safe and effective missions to NEAs.

The BHP group also assisted with astronaut selection at every selection cycle beginning in 1991. Following STS 107, an event that spawned an increased need of behavioral health support to STS crew members and their dependants, BHP services to the Space Shuttle Program were enhanced beginning with the STS 11 4 Return to Flight mission in 2005. These services included the presence of BHP personnel at STS launches and landings for contingency support, a BHP briefing to the entire STS crew at L-11 months, a private preflight meeting with the STS Commander at L-9 months, and the presence of a BHP consultant at the L-1.5 month Family Support Office briefing to crew and family members. The later development of an annual behavioral health assessment of all active astronauts also augmented BHP's Space Shuttle Program specific services, allowing for private meetings with all STS crew members before and after each mission. The components of each facet of these BHP Space Shuttle Program support services will be presented, along with valuable lessons learned, and with recommendations for BHP involvement in future short duration space missions.

Prior to the first launch, detailed coordination, planning and simulations were conducted at all three locations and internal rescue procedures were taught at Kennedy Space Center (KSC). Later in the Program, the Transoceanic Abort Landing (TAL) sites were added in Europe and Africa. For the 51 L mission a new TAL site was brought on line in Morocco. However, upon launch, the Shuttle Program experienced it's first lost. During the following months a complete review of all contingency operations (launch and landing) was completed. Many enhancements were made based on the reviews following. A Mode VIII water rescue was developed for NASA by the DoD before the STS-26 launch. Different concepts were explored and being debated by NASA. Training of the contingency forces was required before final decisions were made forcing the teaching of two different sets of procedures. To assist with training, a video was developed for the fire/crash/rescue personnel. This accompanied the detailed extraction procedures that were developed by a combination of KSC and DoD firemen. Training for the fire/crash/rescue personnel at Vandenberg AFB was also being planned before the accident happen. The fire/crash/rescue mockup that was being built at Chanute AFB was diverted to Edwards AFB.

Given this context, both researchers and operational training and engineering experts have suggested that communication delays and the impact these delays have on the quality of communications to the crew will create performance decrements if crews are not given adequate training and tools to support more autonomous operations. This presentation will provide an overview of a research study led by the Behavioral Health and Performance Element (BHP) of the NASA Human Research Program that examines the impact of implementing a communication delay on the International Space Station (ISS) on individual and team factors and outcomes, including performance and related perceptions of autonomy. The methodological design, use of analog environments, and implementation of this study will be discussed. In addition, the effective collaborations between research and operational personnel at NASA JSC that have provided the adequate support needed in order to make this study successful will also be reviewed. Results of this study will provide a preliminary understanding of the impact of communication delays on individual and team performance as well as insight into how teams perform and interact in a space-like environment.

Materials offgassing had been a manageable concern since the Apollo days, but we learned to pay careful attention to compounds that could escape containment, to combustion events, to toxic propellants, to overuse of utility compounds, and to microbial and human metabolites. We also learned that flying real-time hardware to monitor air pollutants was a pathway with unanticipated speed bumps. Each new orbiter was tested for any excess offgassing products that could pollute the air during flight. In the late 1990s toxicologists and safety experts developed a 5-level toxicity rating system to guide containment of toxic compounds. This system is now in use aboard the International Space Station (ISS). Several combustion events during Shuttle Mir and also during Shuttle free-flight impelled toxicologists to identify hardware capable of monitoring toxic products; however, rapid adaptation of the hardware for the unique conditions of spaceflight caused unexpected missteps. Current and planned combustion analyzers would be useful to commercial partners that wish to manage the risk of health effects from thermal events. Propellants received special attention during the Shuttle program because of the possibility of bringing them into the habitable volume on extravehicular activity suits. Monitors for the airlocks were developed to mitigate this risk. Utility materials, such as lubricants, posed limited toxicological problems because water was not recovered. One clearly documented case of microbial metabolites polluting the Shuttle atmosphere was noted, and this has implications for commercial flights and control of microbes. Finally, carbon dioxide, the major human metabolite, episodically presented air quality problems aboard Shuttle, especially when nominal air flows were obstructed. Commercial vehicles must maintain robust air circulation given the anticipated high density of human occupants.

The establishment of these repositories forms the foundation for the release of data and information beyond the scope for which the data was originally collected. The release of clinical and research data and information is primarily managed by two NASA groups: the Evidence Base Working Group (EESWG), consisting of members of both repositories, and the LSAH Policy Board. The goal of unifying these repositories and their processes is to provide a mutually supportive approach to handling medical and research data, to enhance the use of medical and research data to reduce risk, and to promote the understanding of space physiology, countermeasures and other mitigation strategies. Over the past year, both repositories have received over 100 data and information requests from a wide variety of requesters. The disposition of these requests has highlighted the challenges faced when attempting to make data collected on a unique set of subjects available beyond the original intent for which the data were collected. As the EBWG works through each request, many considerations must be factored into account when deciding what data can be shared and how - from the Privacy Act of 1974 and the Health Insurance Portability and Accountability Act (HIPAA), to NASA's Health Information Management System (10HIMS) and Human Experimental and Research Data Records (10HERD) access requirements. Additional considerations include the presence of the data in the repositories and vetting requesters for legitimacy of their use of the data. Additionally, fair access must be ensured for intramural, as well as extramural investigators. All of this must be considered in the formulation of the charters, policies and workflows for the human data repositories at NASA.

The evolution of the medical standards and care of the Shuttle Era Astronauts began in 1959 with the first Astronaut selection. The first set of NASA minimal medical standards were documented in 1977 and based on Air Force, Navy, Department of Defense, and the Federal Aviation Administration standards. Many milestones were achieved over the 30 years from 1977 to 2007 and the subsequent 13 Astronaut selections and 4 major expert panel reviews performed by the NASA Flight Medicine Clinic, Aerospace Medicine Board, and Medical Policy Board. These milestones of aerospace medicine standards, evaluations, and clinical care encompassed the disciplines of preventive, occupational, and primary care medicine and will be presented. The screening and retention standards, testing, and specialist evaluations evolved through periodic expert reviews, evidence based medicine, and Astronaut medical care experience. The last decade of the Shuttle Program saw the development of the International Space Station (ISS) with further Space medicine collaboration and knowledge gained from our International Partners (IP) from Russia, Canada, Japan, and the European Space Agencies. The Shuttle Program contribution to the development and implementation of NASA and IP standards and waiver guide documents, longitudinal data collection, and occupational surveillance models will be presented along with lessons learned and recommendations for future vehicles and missions.

A century of aviation evolution has resulted in accepted standards in the design of human-machine interfaces - the displays and controls which serve to optimize safe and efficient flight operations and situational awareness. The current proliferation of non-standard, aircraft-specific flight crew interfaces in UAS, coupled with the inherent [imitations of operating UAS without in-situ sensory input and feedback (aural, visual, and vestibular cues), has increased the risk of mishaps associated with the design of the "cockpit". A concerted effort is required to establish standards for the human-machine interfaces. METHODS: NASA's recent experiences with flying its MQ-9 Predator-B in the NAS for extended duration, for wildfire geo-location, has enabled both NASA and the FAA to realize the full potential for UAS, as well as understand the implications of limitations. This effort included an extensive process to obtain flight clearance from the FAA to operate under special provisions, given that UAS in general do not fully comply with current airspace regulations. RESULTS: Missions up to 20 hours in duration have yielded real time data, transmitted via satellite directly to the incident commanders. Their responses are indicative of this success; e.g. "...lives and property saved." The successes of this effort, though outwardly evident by these results, were also contingent on the ability of the flight crew to account for the limitations of operating UAS. DISCUSSION: Key factors that contribute to the limitations of flying UAS as routinely as manned aircraft include inability to "see and avoid" other aircraft and the deprivation of sound and vestibular cues which contribute to a pilot's situational awareness of the aircraft's flying performance and navigation situation. It is imperative that the design of the ground control station, with its suite of displays and controls, must account for these limitations and allow for relative ease of the pilot to interpret and respond in a safe and efficient manner. The definition of "pilot" is experiencing a paradigm shift as knowledge and skill sets are recognized as unique to these aircraft.

In 1997, NASA introduced the planar hard upper torso (HUT) EVA spacesuit which subsequently replaced the existing pivoted HUT. An extra joint in the pivoted shoulder allows increased mobility but also increased complexity. Over the next decade a number of astronauts developed shoulder problems requiring surgical intervention, many of whom performed EVA training in the NBL. This study investigated whether changing HUT designs led to shoulder injuries requiring surgical repair. METHODS: US astronaut EVA training data and spacesuit design employed were analyzed from the NBL data. Shoulder surgery data was acquired from the medical record database, and causal mechanisms were obtained from personal interviews. Analysis of the individual HUT designs was performed as it related to normal shoulder biomechanics. RESULTS: To date, 23 US astronauts have required 25 shoulder surgeries. Approximately 48% (11/23) directly attributed their injury to training in the planar HUT, whereas none attributed their injury to training in the pivoted HUT. The planar HUT design limits shoulder abduction to 90 degrees compared to approximately 120 degrees in the pivoted HUT. The planar HUT also forces the shoulder into a forward flexed position requiring active retraction and extension to increase abduction beyond 90 degrees. DISCUSSION: Multiple factors are associated with mechanisms leading to shoulder injury requiring surgical repair. Limitations to normal shoulder mechanics, suit fit, donning/doffing, body position, pre-existing injury, tool weight and configuration, age, in-suit activity, and HUT design have all been identified as potential sources of injury. Based on this preliminary analysis, crewmembers with pre-existing or current shoulder injuries or certain anthropometric body types should conduct NBL EVA training in the pivoted HUT.

Inherent in the Shuttle operational environment were a number of factors affecting circadian synchronization, sleep and performance including unusual shift work schedules and non-24-hour work days, inappropriate lighting cues, noise, high and low temperature, high carbon dioxide levels, gravitational transitions, high workloads, and other factors experienced during pre, in, and post-flight operations. Spaceflight research and flight surgeon debriefs demonstrated that crewmember sleep on Shuttle often averaged less than 6 hours per night with astronauts routinely exposed to chronic sleep deficiency (Barger et al., 2010). Notably, sleep medications were one of most frequently used medications in the US Shuttle program (Putcha, et al. 1999; Kertzman 2011). There were also ground-based risks. Shuttle Mission Control personnel were often required to undertake shift work or work unusual work schedules and a large proportion of spaceflight personnel were regularly required to travel overseas for training purposes, further impairing sleep due to Jet Lag Disorder. This presentation will review the ground and in-flight research conducted during the Shuttle Program and present the lessons learned and recommendations for future International Space Station mission operations and short-duration vehicle development. Ramifications for missions beyond low-Earth orbit to asteroids or Mars will also be highlighted. It will briefly discuss the recent implementation plans for the development of a Fatigue Management Team and additional countermeasures, for example specialized lighting, by the NASA ISC Behavioral Health and Performance Element of Space Medicine Division, Human Research Program in collaboration with the Clinical Services Branch in the Space Medicine Division.

Results of data mining efforts to assess minor clinical conditions occurring during Shuttle flights STS-1 through STS-94 revealed that space motion sickness (SMS) was the most common ailment during early flight days, occurring in ~40% of crewmembers, followed by digestive system disturbances (9%) and infectious diseases, which most commonly involved the respiratory or urinary tracts. A more recent analysis of postflight medical debriefs data to examine trends with respect to medication use by astronauts during spaceflights indicated that ~37% of all prescriptions recorded was for pain followed by sleep (22%), SMS (18%), decongestion (14%), and all others (14%). Further analysis revealed that about 150 of 317 crewmembers experienced symptoms of SMS. Nearly all (132 of 150) crewmembers took medication for the treatment of symptoms with a total of 387 doses. Promethazine was taken most often (201 doses); in most cases this resulted in alleviation of symptoms with 130 crewmembers (65%) reporting feeling much or somewhat better. Although fewer total doses of the combination of promethazine and dextroamphetamine (Phen/Dex) were taken (45 doses), slightly more than half of these doses resulted in improvement. The combination of scopolamine and dextroamphetamine (Scop/Dex) was reported to be effective in only 37% of cases, with 36 of 97 total doses resulting in improvement. A higher percentage (24%) of Scop/Dex doses was reported to be ineffective compared with promethazine alone or as Phen/Dex (10% and 7%, respectively). Comparisons of the effectiveness of the different dosage forms of promethazine revealed that intramuscular injection was most effective in alleviating symptoms with 55% feeling much better, 16% feeling somewhat better, and only 7% feeling no effect or worse. Overall, it appears that promethazine alone was used more frequently during flight and was reported effective for the treatment of SMS.

NASA TM 2008-214775, NASA TP 2007-213726), but less attention has been paid to using these same competencies to evaluate the efficacy of the training itself (rather than just student efficacy). This presentation will summarize one proposed method of evaluating training efficacy using existing psychosocial competencies for ISS crewmembers. Ideas for collecting both quantitative and qualitative measures of training efficacy and for how to relate these measures to the development of psychosocial competencies will be included.

NASA has identified three primary cardiovascular risks associate with short-duration (less than 18 d) spaceflight: orthostatic intolerance; decreased maximal oxygen uptake; and cardiac arrhythmias. Orthostatic hypotension (OH) was observed postflight in Mercury astronauts, studied in Gemini and Apollo astronauts, and tracked as it developed in-flight during Skylab missions. A putative hypotensive episode in the pilot during an early shuttle landing, and well documented postflight hypotension in a quarter of crewmembers, catalyzed NASA's research effort to understand its mechanisms and develop countermeasures. Shuttle investigations documented the onset of OH, tested mechanistic hypotheses, and demonstrated countermeasures both simple and complex. Similarly, decreased aerobic capacity in-flight threatened both extravehicular activity and post-landing emergency egress. In one study, peak oxygen uptake and peak power were significantly decreased following flights. Other studies tested hardware and protocols for aerobic conditioning that undergird both current practice on long-duration International Space Station (ISS) missions and plans for interplanetary expeditions. Finally, several studies suggest that cardiac arrhythmias are of less concern during short-duration spaceflight than during long-duration spaceflight. Duration of the QT interval was unchanged and the frequency of premature atrial and ventricular contractions was actually shown to decrease during extravehicular activity. These investigations on short-duration Shuttle flights have paved the way for research aboard long-duration ISS missions and beyond. Efforts are already underway to study the effects of exploration class missions to asteroids and Mars.

Outcomes of the research were understanding the effect of spaceflight on human physiology and performance, countermeasures, operational protocols, and hardware. The Shuttle flights were relatively short, < 16 days and routinely had 4 to 6 crewmembers for a total of 135 flights. Biomedical research was conducted on the Space Shuttle using various vehicle resources. Specially constructed pressurized laboratories called Spacelab and SPACEHAB housed many laboratory instruments to accomplish experiments in the Shuttle's large payload bay. In addition to these laboratory flights, nearly every mission had dedicated human life science research experiments conducted in the Shuttle middeck. Most Shuttle astronauts participated in some life sciences research experiments either as test subjects or test operators. While middeck experiments resulted in a low sample per mission compared to many Earth-based studies, this participation allowed investigators to have repetition of tests over the years on successive Shuttle flights. In addition, as a prelude to the International Space Station (ISS), NASA used the Space Shuttle as a platform for assessing future ISS hardware systems and procedures. The purpose of this panel is to provide an understanding of science integration activities required to implement Shuttle research, review biomedical research, characterize countermeasures developed for Shuttle and ISS as well as discuss lessons learned that may support commercial crew endeavors. Panel topics include research integration, cardiovascular physiology, neurosciences, skeletal muscle, and exercise physiology. Learning Objective: The panel provides an overview from the Space Shuttle Program regarding research integration, scientific results, lessons learned from biomedical research and countermeasure development.

The storm surge associated with these systems is an important factor contributing to inundation of coastal areas, and the potential for property damage and loss of life due to storm surge and flooding necessitates accurate predictions of high water levels associated with storm conditions. In addition, the expected global sea level rise over the next century will extend the zone of impact from storms and storm surge farther inland, therefore research on the characterization of these storms and their impact in a future climate is also necessary. In a series of previous studies (Salmun et al., 2009; 2011) we suggested the use of statistical models to aid in surge forecasting. We developed and evaluated a regression equation relating the storm-maximum value of storm surge at The Battery, N. Y., to the average significant wave height during the storm measured at a nearby buoy. We tested the predictive capability of the regression relation with a series of retrospective forecasts of storms and significant wave heights and showed that the statistical prediction of storm-maximum surge had a smaller mean error than that of NOAA's uncorrected extratropical storm-surge forecast and equivalent to the bias corrected operational forecast. In this presentation, we discuss two aspects of the extension of our results. 1) We investigated the applicability of the statistical model to a large geographical region and showed that the regression relation can be "trained" with data from water gauge measurements and near-shore buoys along the east coast from North Carolina to Maine, and that it provides reasonable estimates of storm maximum storm surge. 2) We used the statistical model as a bias correction for operationally produced predictions using NOAA's dynamical models, and showed that the use of the statistical surge prediction as a bias correction for the entire time series of the storm surge related to a storm event is statistically equivalent to the existing bias correction technique. We argue that this "correction" is applicable for much longer lead times and can also be used to aid in the characterization of storm surge and inundations in future climates scenarios.

However, in situ observations in these often remote locations are too sparse to determine the feedbacks responsible for enhanced warming rates. One of these feedbacks is associated with the sensitivity of longwave downward radiation (LDR) to changes in water vapor, with the sensitivity being particularly large in many high-elevation regions where the average water vapor is often low. We show that satellite retrievals from the Moderate Resolution Imaging Spectroradiometer (MODIS) and Clouds and the Earth's Radiant Energy System (CERES) can be used to expand the current ground-based observational database and that the monthly averaged clear-sky satellite estimates of humidity and LDR are in good agreement with the well-instrumented Center for Snow and Avalanche Studies ground-based site in the southwestern Colorado Rocky Mountains. The relationship between MODIS-retrieved precipitable water vapor and surface specific humidity across the contiguous United States was found to be similar to that previously found for the Alps. More important, we show that satellites capture the nonlinear relationship between LDR and water vapor and confirm that LDR is especially sensitive to changes in water vapor at high elevations in several midlatitude mountain ranges. Because the global population depends on adequate fresh water, much of which has its source in high mountains, it is critically important to understand how climate will change there. We demonstrate that satellites can be used to investigate these feedbacks in high-elevation regions where the coverage of surface-based observations is insufficient to do so.

By defining data at 4-km horizontal resolutions and 1-h temporal resolutions as an individual precipitating or nonprecipitating sample, statistics of rain occurrence and rain volume including their geographical and seasonal variations are documented. Quantitative estimations are also conducted to evaluate the impact of missing light rain events due to satellite sensors' detection capabilities. It is found that statistics of rain characteristics have large seasonal and geographical variations across the continental United States. Although heavy rain events (>10 mm h super(-1)) only occupy 2.6% of total rain occurrence, they may contribute to 27% of total rain volume. Light rain events (<1.0 mm h super(-1)), occurring much more frequently (65%) than heavy rain events, can also make important contributions (15%) to the total rain volume. For minimum detectable rain rates setting at 0.5 and 0.2 mm h super(-1), which are close to sensitivities of the current and future spaceborne precipitation radars, there are about 43% and 11% of total rain occurrence below these thresholds, and they respectively represent 7% and 0.8% of total rain volume. For passive microwave sensors with their rain pixel sizes ranging from 14 to 16 km and the minimum detectable rain rates around 1 mm h super(-1), the missed light rain events may account for 70% of rain occurrence and 16% of rain volume. Statistics of rain characteristics are also examined on domains with different temporal and spatial resolutions. Current issues in estimates of rain characteristics from satellite measurements and model outputs are discussed.

The Modern-Era Retrospective Analysis for Research and Applications (MERRA) is used as the main investigating tool. MERRA is compared with other reanalyses datasets from major operational centers around the world and was found to describe very effectively the circulation over the African monsoon region. In particular, a comparison with precipitation datasets from the Global Precipitation Climatology Project shows that MERRA realistically reproduces seasonal precipitation over that region. The verification of the generalized Kuo barotropic instability condition computed from seasonal means is found to have the interesting property of defining well the location where observed tropical storms are detected. This property does not appear to be an artifact of MERRA and is present also in the other adopted reanalysis datasets. Therefore, the fact that the areas where the mean flow is unstable seems to provide a more favorable environment for wave intensification, could be another factor to include-in addition to sea surface temperature, vertical shear, precipitation, the role of Saharan air, and others-among large-scale forcings affecting development and tropical cyclone frequency. In addition, two prominent modes of variability are found based on a spectral analysis that uses the Hilbert-Huang transform: a 2.5-6-day mode that corresponds well to the African easterly waves and also a 6-9-day mode that seems to be associated with tropical-extratropical interaction.

However, given that several processes potentially contributed, relatively little is understood about the reasons for the observed warmth, or the associated polar amplification. Here, using a modelling approach and a novel factorisation method, we assess the relative contributions to mid-Pliocene warmth from: elevated CO (sub 2) , lowered orography, and vegetation and ice sheet changes. The results show that on a global scale, the largest contributor to mid-Pliocene warmth is elevated CO (sub 2) . However, in terms of polar amplification, changes to ice sheets contribute significantly in the Southern Hemisphere, and orographic changes contribute significantly in the Northern Hemisphere. We also carry out an energy balance analysis which indicates that that on a global scale, surface albedo and atmospheric emmissivity changes dominate over cloud changes. We investigate the sensitivity of our results to uncertainties in the prescribed CO (sub 2) and orographic changes, to derive uncertainty ranges for the various contributing processes.

Local electrode atom probe analysis was conducted at 2, 13, and 25 mu m distance from the oxide/base-metal interface. Oxygen was preferentially located in the alpha sub(2) phase with concentrations up to 14.8 at.% and diminishing with increasing distance from the surface. Near surface microstructural changes were only visible up to 10 mu m from the surface but the oxygen diffusion significantly exceeded that distance. The diffusion coefficient of oxygen into the alpha sub(2) phase was estimated based on the oxygen concentrations obtained from local electrode atom probe analysis. Fluorine ion implantation on the surface was investigated as a possible solution to the embrittlement.

N1 - Last updated - 2012-02-16 ER - TY - JOUR T1 - U-Th-Pb isotope data indicate Phanerozoic age for oxidation of the 3.4 Ga Apex Basalt AN - 1026857921; 2012-064757 AB - The occurrence of ferric oxides in Archean rocks has played an important role in discussions on the amount of free oxygen in the atmosphere of the ancient Earth. Recognizing that post-Archean weathering may also produce oxide minerals, drill cores have been used to obtain samples beneath the depth of Phanerozoic weathering. The first core of the Archean Biosphere Drilling Project (ABDP-1) documented hematite as alteration products in 3.4 Ga basalts from the Marble Bar area of the Pilbara Craton, NW Australia, and this has been used to infer the presence of an O (sub 2) -bearing atmosphere in the Archean. It is possible, however, that despite recovery of samples from >100m depth, oxidation of the basalts occurred much younger than the depositional age. In this study, the age of oxidation of the Apex Basalt from the ABDP-1 drill core at Marble Bar is constrained by U-Th-Pb geochronology. Lead and U concentrations of the basalts from the ABDP-1 drill core vary greatly, between <1-58 ppm and 0.08-1.04 ppm, respectively, whereas Th contents are more restricted (0.24-0.71 ppm). (super 206) Pb/ (super 204) Pb ratios are non-radiogenic and vary from 12.44 to 14.69. The linear array in terms of (super 206) Pb/ (super 204) Pb- (super 207) Pb/ (super 204) Pb variations does not reflect an age but reflects two-component mixing between a non-radiogenic "ore lead" end member and a radiogenic "basalt lead" end member. The samples do not form isochrons on (super 238) U/ (super 204) Pb- (super 206) Pb/ (super 204) Pb, (super 235) U/ (super 204) Pb- (super 207) Pb/ (super 204) Pb, or (super 232) Th/ (super 204) Pb- (super 208) Pb/ (super 204) Pb diagrams, indicating post-formation U and Pb addition. Comparison of measured U/Th ratios with "model" U/Th ratios calculated based on (super 208) Pb/ (super 204) Pb- (super 206) Pb/ (super 204) Pb variations indicates that U enrichment most likely occurred in the last 200 Ma. The degree of U enrichment in the samples is correlated with Fe (super (III)) /Fe (sub Total) ratios, indicating that U addition and oxidation were related, most likely reflecting penetration of oxygenated surface waters in the Phanerozoic along bedding planes and shear zones. These results, therefore, indicate that oxidation of the Apex Basalt did not occur in the Archean, and therefore cannot be used to infer an oxygenated atmosphere at that time.

N1 - Last updated - 2012-02-07 ER - TY - JOUR T1 - The 2010 Pakistan Flood and Russian Heat Wave: Teleconnection of Hydrometeorological Extremes AN - 968181694; 16428032 AB - In this paper, preliminary results are presented showing that the two record-setting extreme events during 2010 summer (i.e., the Russian heat wave-wildfires and Pakistan flood) were physically connected. It is found that the Russian heat wave was associated with the development of an extraordinarily strong and prolonged extratropical atmospheric blocking event in association with the excitation of a large-scale atmospheric Rossby wave train spanning western Russia, Kazakhstan, and the northwestern China-Tibetan Plateau region. The southward penetration of upper-level vorticity perturbations in the leading trough of the Rossby wave was instrumental in triggering anomalously heavy rain events over northern Pakistan and vicinity in mid- to late July. Also shown are evidences that the Russian heat wave was amplified by a positive feedback through changes in surface energy fluxes between the atmospheric blocking pattern and an underlying extensive land region with below-normal soil moisture. The Pakistan heavy rain events were amplified and sustained by strong anomalous southeasterly flow along the Himalayan foothills and abundant moisture transport from the Bay of Bengal in connection with the northward propagation of the monsoonal intraseasonal oscillation.

The rain gauge sites were separated between 0.4 and 5 km, matching the beamwidth of Tropical Rainfall Measuring Mission (TRMM) and Global Precipitation Measurement (GPM) precipitation radars. During a 2-yr observational period, over 7100 rainy samples were received at 5-min integration. A single gauge did not report as high as 67% of the time when at least one of the other gauges had rainfall in one of the seasons. Since rainfall from one of the six rain gauges is sufficient for the rainy footprint from a satellite, this demonstrates the common occurrence of the partial beamfilling. For the periods where all gauges were reporting rainfall, a single gauge had at most 13% difference from the areal average rainfall in one of the seasons. This suggests that at the spatial scale of 5 km, the variability caused by the rain gradient is relatively less important than the variability arising from a partially filled footprint. During the passage of frontal systems and tropical cyclones, the beam was filled by rain most of the time and this resulted in relatively higher correlation distances. The correlation distance had a sharp drop off from 45 km in moderately variable rainfall to 3 km in highly variable rainfall and ranged from 5 to 35 km between the different seasons. This demonstrates its highly variable nature. Considering temporal sampling, the monthly rainfall error was 35% and 73% for 3-hourly and twice-daily observations, respectively.

Snow initialization has a major impact on skill during the spring melting season. Soil moisture initialization has a smaller but still statistically significant impact during this season, and in other seasons, its contribution to skill dominates. Realistic soil moisture initialization can contribute to skill at long leads (over 6 months) for certain basins and seasons. Skill levels in all seasons are found to be related to the ratio of initial total water storage (soil water plus snow) variance to the forecast period precipitation variance, allowing estimates of the potential for skill in areas outside the verification basins.

Characterizing both the spatiotemporal variability and the fidelity of these exchanges of heat and moisture is critical to understanding the global water and energy cycle variations, quantifying atmosphere-ocean feedbacks, and improving model predictability. This study examines the veracity of the recently completed NASA Modern-Era Retrospective Analysis for Research and Applications (MERRA) product in terms of its turbulent surface fluxes. This assessment employs a large dataset of directly measured turbulent fluxes as well as other turbulent surface flux datasets. The spatial and temporal variability of the surface fluxes are examined in terms of their annual-mean climatologies, their seasonal covariability of near-surface bulk parameters, and their representation of extremes. The impact of data assimilation on the near-surface parameters is assessed through evaluation of the incremental analysis update tendencies. It is found that MERRA turbulent surface fluxes are relatively accurate for typical conditions but have systematically weak vertical gradients in moisture and temperature and a weaker covariability between the near-surface gradients and wind speed than found in observations. This results in an underestimate of the surface latent and sensible heat fluxes over the western boundary current and storm-track regions. The assimilation of observations generally acts to bring MERRA closer to observational products by increasing moisture and temperature near the surface and decreasing the near-surface wind speeds.

AN - 923193818; 22280102 AB - The impurity-free aqueous dispersions of boron nitride nanosheets (BNNS) allowed the facile preparation of silver (Ag) nanoparticle-decorated BNNS by chemical reduction of an Ag salt with hydrazine in the presence of BNNS. The resultant Ag-BNNS nanohybrids remained dispersed in water, allowing convenient subsequent solution processing. By using substrate transfer techniques, Ag-BNNS nanohybrid thin film coatings on quartz substrates were prepared and evaluated as reusable surface enhanced Raman spectroscopy (SERS) sensors that were robust against repeated solvent washing. In addition, because ofthe unique thermal oxidation-resistant properties of the BNNS, the sensor devices may be readily recycled by short-duration high temperature air oxidation to remove residual analyte molecules in repeated runs. The limiting factor associated with the thermal oxidation recycling process was the Ostwald ripening effect of Ag nanostructures.

On the basis of a greatly expanded set of spectroscopic parameters, we built a full non-resonance cascade fluorescence model and computed fluorescence efficiencies for H sub(2)O (500 million lines) and HDO (700 million lines). The new line list was also integrated into an advanced terrestrial radiative transfer code (LBLRTM) and adapted to the CO sub(2) rich atmosphere of Mars, for which we adopted the complex Robert-Bonamy formalism for line shapes. We retrieved water and D/H in the atmospheres of Mars, comet C/2007 W1 (Boattini), and Earth by applying the new formalism to spectra obtained with the high-resolution spectrograph NIRSPEC/Keck II atop Mauna Kea (Hawaii). The new model accurately describes the complex morphology of the water bands and greatly increases the accuracy of the retrieved abundances (and the D/H ratio in water) with respect to previously available models. The new model provides improved agreement of predicted and measured intensities for many H sub(2)O lines already identified in comets, and it identifies several unassigned cometary emission lines as new emission lines of H sub(2)O. The improved spectral accuracy permits retrieval of more accurate rotational temperatures and production rates for cometary water.

Our aim here is to prove, mathematically, that the two-source paradigm can be derived using a minimum number of self-consistent approximations based on our current knowledge of jet turbulence in cold flows. The starting point of the paper is Goldstein's (2003) exact re-arrangement of the Navier-Stokes equations, which shows that turbulence enters the acoustic spectrum formula through the Reynolds stress auto-covariance tensor. We extend the shell model of turbulence using a more general symmetry approximation that amounts to assuming that the Reynolds stress auto-covariance is, firstly, axi-symmetric, and secondly is equivalent to the same tensor only after it has been averaged (point-wise) over the azimuthal separation. As a consequence of these two assumptions, the space-time Fourier transform of the Reynolds stress auto-covariance (which we refer to as the spectral tensor) depends on the transverse wave vector only through the square of its magnitude and, moreover, is also an axi-symmetric tensor. This defines the generalized shell model (or GSM) and we apply it to the jet noise problem. The final result shows that the acoustic spectrum can be written as the sum of two groups of terms, one of which corresponds to the peak jet noise in the weakly non-parallel flow limit.

In renewable energy applications, space-based observations now routinely augment sparse ground-based observations used as input for renewable energy resource assessment applications. As one of the nine Group on Earth Observations (GEO) societal benefit areas, the enhancement of management and policy decision making in the energy sector is receiving attention in activities conducted by the Committee on Earth Observation Satellites (CEOS). CEOS has become the "space arm" for the implementation of the Global Earth Observation System of Systems (GEOSS) vision. It is directly supporting the space-based, near-term tasks articulated in the GEO three-year work plan. This paper describes a coordinated program of demonstration projects conducted by CEOS member agencies and partners to utilize Earth observations to enhance energy management end-user decision support systems. We discuss the importance of engagement with stakeholders and understanding their decision support needs in successfully increasing the uptake of Earth observation products for societal benefit. Several case studies are presented, demonstrating the importance of providing data sets in formats and units familiar and immediately usable by decision makers. These projects show the utility of Earth observations to enhance renewable energy resource assessment in the developing world, forecast space weather impacts on the power grid, and improve energy efficiency in the built environment.

Over 17 million people live in the Bay's watershed, and the ever-increasing population has had adverse impacts on the health of the land and water super(1). More people generally means more nutrients going to septic systems or wastewater treatment plants; more tunoff from roads, driveways, rooftops, and other impervious surfaces; more intensive farming; and more air pollution as people drive farther--and all these "pollution sources" eventually make their way toward the Chesapeake. In recent years, the health of the Bay has become a subject of great interest and concern, and has been closely monitored using in situ sampling methods and modeling super(2). Increasingly, satellite data--including near-real-time (NRT) data from the Moderate Resolution Imaging Spectroradiometer (MODIS) on the Terra and Aqua platforms--are being added to the palate of tools that researchers have at their disposal to help them keep tabs on the health of this irreplaceable natural resource.

The characteristics of the host star are well constrained by high-resolution spectroscopy combined with an asteroseismic analysis of the Kepler photometry, leading to an estimated mass and radius of 0.970 + or - 0.060 M [] and 0.979 + or - 0.020 R []. The depth of 492 + or - 10 ppm for the three observed transits yields a radius of 2.38 + or - 0.13 Re for the planet. The system passes a battery of tests for false positives, including reconnaissance spectroscopy, high-resolution imaging, and centroid motion. A full BLENDER analysis provides further validation of the planet interpretation by showing that contamination of the target by an eclipsing system would rarely mimic the observed shape of the transits. The final validation of the planet is provided by 16 radial velocities (RVs) obtained with the High Resolution Echelle Spectrometer on Keck I over a one-year span. Although the velocities do not lead to a reliable orbit and mass determination, they are able to constrain the mass to a 3sigma upper limit of 124 M, safely in the regime of planetary masses, thus earning the designation Kepler-22b. The radiative equilibrium temperature is 262 K for a planet in Kepler-22b's orbit. Although there is no evidence that Kepler-22b is a rocky planet, it is the first confirmed planet with a measured radius to orbit in the habitable zone of any star other than the Sun.

One of the earliest night-time images from the ISS was the US-Mexico border at El Paso-Ciudad Juarez. The colors, patterns and density of city lights document the differences in the cultural settlement patterns across the border region, as well as within the urban areas themselves. City lights help outline the most populated areas in settlements around the world, and can be used to explore relative population densities, changing patterns of urban/suburban development, transportation networks, spatial relationship to geographic features, and more. These data also provide insight into parameters such as surface roughness for input into local and regional climate modeling and studies of light pollution. The ground resolution of night-time astronaut photography from the ISS is typically an order of magnitude greater than current Defense Meteorological Satellite Program (DMSP) data, and therefore can serve as a "zoom lens" for selected urban areas. Current handheld digital cameras in use on the ISS, optimized for greater light sensitivity, provide opportunities to obtain new detailed imagery of atmospheric phenomena such as airglow, aurora, and noctilucent clouds in addition to documenting urban patterns. ISS astronauts have taken advantage of increasingly sensitive digital cameras to document the world at night in unprecedented detail. In addition, the capability to obtain time-lapse imagery from fixed cameras has been exploited to produce dynamic videos of both changing surface patterns around the world and atmospheric phenomena. We will profile some spectacular images of human settlements over the South-Central U.S., and contrast with other images from around the world.

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

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

Testing included echocardiographic analysis of cardiac function, plasma volume (PV), aerobic power (VO sub(2)pk) and cardiovascular and neuroendocrine responses to 80 super(o) head-up tilt (HUT). Data collected during HUT were ECG, stroke volume (SV), blood pressure (BP) and blood for catecholamines and vasoactive hormones. Heart rate (HR), cardiac output (CO), total peripheral resistance, and spectral power of BP and HR were calculated. Bed rest decreased PV, supine and HUT SV, and indices of cardiac function in both groups. Although PV was decreased in control and AG after bed rest, AG attenuated the decrease in orthostatic tolerance [pre- to post-bed rest change; control: -11.8 plus or minus 2.0, AG: -6.0 plus or minus 2.8 min (p = 0.012)] and VO sub(2)pk [pre- to post-bed rest change; control: -0.39 plus or minus 0.11, AG: -0.17 plus or minus 0.06 L/min (p = 0.041)]. AG prevented increases in pre-tilt levels of plasma renin activity [pre- to post-bed rest change; control: 1.53 plus or minus 0.23, AG: -0.07 plus or minus 0.34 ng/mL/h (p = 0.001)] and angiotensin II [pre- to post-bed rest change; control: 3.00 plus or minus 1.04, AG: -0.63 plus or minus 0.81 pg/mL (p = 0.009)] and increased HUT aldosterone [post-bed rest; control: 107 plus or minus 30 pg/mL, AG: 229 plus or minus 68 pg/mL (p = 0.045)] and norepinephrine [post-bed rest; control: 453 plus or minus 107, AG: 732 plus or minus 131 pg/mL (p = 0.003)]. We conclude that AG can mitigate some aspects of bed rest-induced cardiovascular deconditioning, including orthostatic intolerance and aerobic power. Mechanisms of improvement were not cardiac-mediated, but likely through improved sympathetic responsiveness to orthostatic stress.

The concept of introducing automated separation assurance was proposed to help solve this problem. However, the introduction of such a concept involves a fundamental paradigm shift in which automation is allowed to perform safety-critical tasks that today are strictly the air traffic controllers' domain. Moving toward automated air traffic control, therefore, requires a careful and thorough investigation. As part of an ongoing series, three human-in-the-loop simulation studies were conducted at the NASA Ames Research Center with the overarching goal of determining whether the automated separation assurance concept can be integrated into air traffic control operations in an acceptable and safe manner. These studies investigated a range of issues including the proper levels of automation for given capacity targets, off-nominal operations from both air and ground perspectives, and sustained near-full mission operations with many tasks allocated to the automation in the presence of convective weather and scheduling constraints. Overall, it was found that the concept has the potential to solve the envisioned airspace capacity problem. The automation was largely effective and robust, and the function allocation of tasks between controllers and automation was generally acceptable. However, feedback and results also showed that further technological development is necessary to improve trajectory prediction and conflict detection accuracy. The need for further procedural development to govern controller/automation and air/ground interactions was also highlighted. These and other considerations are addressed as the automated separation assurance concept is further tested and pursued through subsequent studies.

However, many of these models are subject to structural and parametric uncertainties because of the lack of field measurements. In recent years, the Gravity Recovery and Climate Experiment (GRACE) satellite mission has shown great potential for tracking total water storage changes over large regions. The pattern of groundwater storage changes inferred from GRACE may be incorporated as an additional regulation mechanism for calibrating regional groundwater models. Motivated by the demonstrated success of GRACE for monitoring groundwater storage changes, this study explores the combined use of in situ water level measurements and GRACE-derived groundwater storage changes for calibrating regional groundwater models. The resulting optimization problem is solved using an evolutionary optimization algorithm. We demonstrate the proposed calibration strategy for the hydraulically connected Edwards-Trinity Plateau and Pecos Valley aquifers (total area 115,000 km (super 2) ) in west Texas. Monthly GRACE data from 2002 to 2007 were used to recalibrate a regional groundwater model developed for the area. Our results indicate that (i) calibration using in situ data alone may yield multiple plausible solutions, a phenomenon well known to hydrologists; and (ii) GRACE data helped further constrain model parameters over the study period and, thus, may be continuously assimilated, among other sources of data, for enhancing existing regional groundwater models.

During the last week of September 2011 a large transverse rift developed across the floating terminus of West Antarctica's Pine Island Glacier, less than 5 years after its last large calving event, in 2007. Pine Island Glacier's retreat has accelerated substantially in the past 2 decades, and it is now losing 50 gigatons of ice per year, or roughly 25% of Antarctica's total annual contribution to sea level rise [Rignot et al., 2008]. The glacier's recent accelerated retreat is likely triggered by ocean warming and increased submarine melting. As such, it is of significant interest to glaciologists and of heightened societal relevance.

AN - 914299429; 22172920 AB - To understand the mechanical properties of amorphous carbon (a-C)/boron nitride nanotube (BNNT) nanostructures, in situ mechanical tests are conducted inside a transmission electron microscope equipped with an integrated atomic force microscope system. The nanotube structure is modified with amorphous carbon deposited by controlled electron beam irradiation. We demonstrate multiple in situ tensile, compressive, and lap shear tests with a-C/BNNT hybrid nanostructures. The tensile strength of the a-C/BNNT hybrid nanostructure is 5.29 GPa with about 90 vol% of a-C. The tensile strength and strain of the end-to-end joint structure with a-C welding is 0.8 GPa and 5.2% whereas the lap shear strength of the side-by-side joint structure with a-C is 0.25 GPa.

16108285 AB - The aerosol component of the Oxford-Rutherford Appleton Laboratory (RAL) Aerosol and Clouds (ORAC) retrieval scheme for the Advanced Along-Track Scanning Radiometer (AATSR) uses data derived from the Moderate Resolution Imaging Spectroradiometer (MODIS) to constrain the brightness of the surface. However, the spectral response functions of the channels used (centred near 550nm, 660nm, 870nm, and 1.6 mu m) do not exactly match between the two sensors. It is shown that failure to account for differences between the instruments' spectral response functions leads to errors of typically 0.001-0.01 in spectral surface albedo, and distinct biases, dependent on wavelength and surface type. A technique based on singular value decomposition (SVD) is used to reduce these random errors by an average of 35% at 670nm and over 60% at the other wavelengths used. The technique reduces the biases so that they are negligible. In principle, the method can be extended to any combination of sensors. The SVD-based scheme is applied to AATSR data from the month of July 2008 and found to increase the number of successful aerosol retrievals, the speed of retrieval convergence, and improve the level of consistency between the measurements and the retrieved state. Additionally, retrieved aerosol optical depth at 550nm shows an improvement in correspondence when compared to Aerosol Robotic Network (AERONET) data.

Because the majority (>70%) of the water supply in the western U.S. comes from snowmelt, analysis of the declining spring snowpack (and shrinking glaciers) has important implications for the management of streamflow. The amount of water in a snowpack influences stream discharge which can also influence erosion and sediment transport by changing stream power, or the rate at which a stream can do work, such as move sediment and erode the stream bed. The focus of this work is the Wind River Range (WRR) in west-central Wyoming. Ten years of Moderate-Resolution Imaging Spectroradiometer (MODIS) snow-cover, cloud-gap-filled (CGF) map products and 30years of discharge and meteorological station data are studied. Streamflow data from streams in WRR drainage basins show lower annual discharge and earlier snowmelt in the decade of the 2000s than in the previous three decades, though no trend of either lower streamflow or earlier snowmelt was observed within the decade of the 2000s. Results show a statistically-significant trend at the 95% confidence level (or higher) of increasing weekly maximum air temperature (for three out of the five meteorological stations studied) in the decade of the 1970s, and also for the 40-year study period as a whole. The extent of snow-cover (percent of basin covered) derived from the lowest elevation zone (2500-3000m) of the WRR, using MODIS CGF snow-cover maps, is strongly correlated with maximum monthly discharge on 30 April, where Spearman's Rank correlation, rs,=0.89 for the decade of the 2000s. We also investigated stream power for Bull Lake Creek above Bull Lake; and found a trend (significant at the 90% confidence level) toward reduced stream power from 1970 to 2009. Observed changes in streamflow and stream power may be related to increasing weekly maximum air temperature measured during the 40-year study period, possibly contributing to a reduction in snow cover. In addition, the strong relationship between percent of basin that was snow covered, and maximum monthly streamflow indicates that MODIS snow-cover maps are useful for predicting streamflow, and can be used to improve management of water resources in the drought-prone western United States.

The fraction of Labile Organic Carbon (LOC) in these samples varied from 2 to 73 mu g per gram of soil with a bi-modal distribution with average content of 17+ or -9 mu g LOC and 69+ or -3 mu g LOC for "low" and "high" samples, respectively. Interestingly, there was no relation between organic levels and geomorphologic shapes. While organics are deposited and distributed in these soils via eolic processes, it is suggested that fog is the dynamic mechanism that is responsible for the variability and peaks in organic carbon throughout the area, where a "high" LOC content sample could be indicative of a biological process. It was determined that there was no significant difference between topological feature or geographical position within the hyper-arid samples and LOC. This very curious result has implications for the investigation of run-off gullies on the planet Mars as our work suggests a need for careful consideration of the expectation of increases in concentrations of organic materials associated with following aqueous altered topology.

Although the overall effect of aerosols on solar radiation and clouds is most certainly negative, some individual forcing agents and feedbacks have positive forcing effects. Recent studies have tried to identify some of those positive forcing agents and their individual emission sectors, with the hope that mitigation policies could be developed to target those emitters. Understanding the net effect of multisource emitting sectors and the involved cloud feedbacks is very challenging, and this paper will clarify forcing and feedback effects by separating direct, indirect, semidirect and surface albedo effects due to aerosols. To this end, we apply the Goddard Institute for Space Studies climate model including detailed aerosol microphysics to examine aerosol impacts on climate by isolating single emission sector contributions as given by the Coupled Model Intercomparison Project Phase 5 (CMIP5) emission data sets developed for Intergovernmental Panel on Climate Change (IPCC) AR5. For the modeled past 150 years, using the climate model and emissions from preindustrial times to present-day, the total global annual mean aerosol radiative forcing is -0.6 W/m2, with the largest contribution from the direct effect (-0.5 W/m2). Aerosol-induced changes on cloud cover often depends on cloud type and geographical region. The indirect (includes only the cloud albedo effect with -0.17 W/m2) and semidirect effects (-0.10 W/m2) can be isolated on a regional scale, and they often have opposing forcing effects, leading to overall small forcing effects on a global scale. Although the surface albedo effects from aerosols are small (0.016 W/m2), triggered feedbacks on top of the atmosphere (TOA) radiative forcing can be 10 times larger. Our results point out that each emission sector has varying impacts by geographical region. For example, the single sector most responsible for a net positive radiative forcing is the transportation sector in the United States, agricultural burning and transportation in Europe, and the domestic emission sector in Asia. These sectors are attractive mitigation targets. JF - Journal of Geophysical Research.

We considered approximately 400 emission control measures to reduce these pollutants by using current technology and experience. We identified 14 measures targeting methane and BC emissions that reduce projected global mean warming approximately 0.5 degree C by 2050. This strategy avoids 0.7 to 4.7 million annual premature deaths from outdoor air pollution and increases annual crop yields by 30 to 135 million metric tons due to ozone reductions in 2030 and beyond. Benefits of methane emissions reductions are valued at $700 to $5000 per metric ton, which is well above typical marginal abatement costs (less than $250). The selected controls target different sources and influence climate on shorter time scales than those of carbon dioxide-reduction measures. Implementing both substantially reduces the risks of crossing the 2 degree C threshold.

Satellite derived soil moisture estimates, if retrieved appropriately, represent the spatial mean of near surface soil moisture in a footprint area, and can be used to reduce bias of model estimates (at locations near the surface) through data assimilation techniques. While assimilating the retrievals can reduce bias, it can also destroy the mass balance enforced by the model governing equation because water is removed from or added to the soil by the assimilation algorithm. In addition, studies have shown that assimilation of surface observations can adversely impact soil moisture estimates in the lower soil layers due to imperfect model physics, even though the bias near the surface is decreased. In this study, an ensemble Kalman filter (EnKF) with a mass conservation updating scheme was developed to assimilate Advanced Microwave Scanning Radiometer (AMSR-E) soil moisture retrievals, as they are without any scaling or pre-processing, to improve the estimated soil moisture fields by the Noah land surface model. Assimilation results using the conventional and the mass conservation updating scheme in the Little Washita watershed of Oklahoma showed that, while both updating schemes reduced the bias in the shallow root zone, the mass conservation scheme provided better estimates in the deeper profile. The mass conservation scheme also yielded physically consistent estimates of fluxes and maintained the water budget. Impacts of model physics on the assimilation results are discussed.

N1 - Last updated - 2012-01-04 ER - TY - JOUR T1 - Oxidation pathways for formic acid under low temperature hydrothermal conditions; implications for the chemical and isotopic evolution of organics on Mars AN - 921717368; 2012-022663 AB - In order to evaluate the oxidation effect of dissolved hydrogen peroxide and the catalytic role of iron oxides on the kinetics of formic acid decarboxylation, a series of flow-through hydrothermal experiments was conducted at temperatures ranging from 80 to 150 degrees C and pressures of 172-241 bar. delta (super 13) C composition of residual HCOOH (sub (aq)) was also monitored to examine kinetic isotope effects associated with oxidation processes. Our results reveal that decomposition of H (sub 2) O (sub 2(aq)) in presence of magnetite follows pseudo first order kinetics, highly enhanced relative to the homogeneous H (sub 2) O (sub 2(aq)) -HCOOOH (sub (aq)) -H (sub 2) O system, which possibly reflect synthesis of hydroxyl radicals ( (super .) OH) through Fenton processes. The kinetic rate constants of HCOOH (sub (aq)) decarboxylation to CO (sub 2(aq)) are also elevated relative to those previously measured in H (sub 2) O (sub 2(aq)) free experiments. However, reaction kinetics are slightly slower in the case of H (sub 2) O (sub 2(aq)) aqueous solutions coexisting with magnetite than in the absence of mineral phases. This behavior is attributed to the possible formation of Fe-bearing hydroxyl formate aqueous species that could serve as stable transition states leading to a decrease in the activation entropy of formic acid decomposition. delta (super 13) C values of residual formic acid in the homogeneous H (sub 2) O (sub 2(aq)) -HCOOH (sub (aq)) -H (sub 2) O system are consistent with previous studies. However, magnetite-bearing experiments produce a negative shift in delta (super 13) C of residual formic acid, perhaps specific to (super .) OH-imposed oxidation of organic compounds. This would indicate that isotopic fractionations by this oxidation pathway are opposite to kinetic fractionation effects expected in biologically driven oxidation processes. This could have important implications for putative H (sub 2) O (sub 2(aq)) -bearing Martian subsurface environments and the evolution of organics at low-temperature hydrothermal conditions.

In this paper, we present the results of multiple endmember spectral mixture analysis applied to Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) and Airborne Visible/Infrared Imaging Spectrometer (AVIRIS) imagery, comparing affects of seasonality and spectral resolution on the discrimination of soil, grass/forb, and sagebrush abundance in Yellowstone National Park. Our results showed that AVIRIS, despite late season phenology, correlated well with herbaceous and sagebrush cover field measurements (R super(2) = 0.77 and 0.75, respectively), utilizing high spectral resolution to separate soils from vegetation. However, ASTER-derived values during peak green correlated best with field measurements (0.75 and 0.78). These results demonstrated an effective method to monitor semi-arid regions with readily available imagery and highlight applications for future hyperspectral satellite missions.

N1 - Date revised - 2016-01-01 N1 - PubXState - DC N1 - Last updated - 2016-04-01 ER - TY - JOUR T1 - Mixing of dust and NH (sub 3) observed globally over anthropogenic dust sources AN - 1773800075; 2016-023784 AB - The global distribution of dust column burden derived from MODIS Deep Blue aerosol products is compared to NH (sub 3) column burden retrieved from IASI infrared spectra. We found similarities in their spatial distributions, in particular their hot spots are often collocated over croplands and to a lesser extent pastures. Globally, we found 22% of dust burden collocated with NH (sub 3) , with only 1% difference between land-use databases. This confirms the importance of anthropogenic dust from agriculture. Regionally, the Indian subcontinent has the highest amount of dust mixed with NH (sub 3) (26%), mostly over cropland and during the pre-monsoon season. North Africa represents 50% of total dust burden but accounts for only 4% of mixed dust, which is found over croplands and pastures in Sahel and the coastal region of the Mediterranean. In order to evaluate the radiative effect of this mixing on dust optical properties, we derive the mass extinction efficiency for various mixtures of dust and NH (sub 3) , using AERONET sunphotometers data. We found that for dusty days the coarse mode mass extinction efficiency decreases from 0.62 to 0.48 m (super 2) g (super -1) as NH (sub 3) burden increases from 0 to 40 mg m (super -2) . The fine mode extinction efficiency, ranging from 4 to 16 m (super 2) g (super -1) , does not appear to depend on NH (sub 3) concentration or relative humidity but rather on mineralogical composition and mixing with other aerosols. Our results imply that a significant amount of dust is already mixed with ammonium salt before its long range transport. This in turn will affect dust lifetime, and its interactions with radiation and cloud properties.

It is an online model in which the dust aerosol dynamics and physics are solved at each model time step. The companion paper (Perez et al., 2011) develops the dust model parameterizations and provides daily to annual evaluations of the model for its global and regional configurations. Modeled aerosol optical depth (AOD) was evaluated against AERONET Sun photometers over Northern Africa, Middle East and Europe with correlations around 0.6-0.7 on average without dust data assimilation. In this paper we analyze in detail the behavior of the model using data from the Saharan Mineral dUst experiment (SAMUM-1) in 2006 and the Bodele Dust Experiment (BoDEx) in 2005. AOD from satellites and Sun photometers, vertically resolved extinction coefficients from lidars and particle size distributions at the ground and in the troposphere are used, complemented by wind profile data and surface meteorological measurements. All simulations were performed at the regional scale for the Northern African domain at the expected operational horizontal resolution of 25 km. Model results for SAMUM-1 generally show good agreement with satellite data over the most active Saharan dust sources. The model reproduces the AOD from Sun photometers close to sources and after long-range transport, and the dust size spectra at different height levels. At this resolution, the model is not able to reproduce a large haboob that occurred during the campaign. Some deficiencies are found concerning the vertical dust distribution related to the representation of the mixing height in the atmospheric part of the model. For the BoDEx episode, we found the diurnal temperature cycle to be strongly dependant on the soil moisture, which is underestimated in the NCEP analysis used for model initialization. The low level jet (LLJ) and the dust AOD over the Bodele are well reproduced. The remaining negative AOD bias (due to underestimated surface wind speeds) can be substantially reduced by decreasing the threshold friction velocity in the model.

Antarctic ice core rBC records may thus provide information with respect to past combustion aerosol emissions and atmospheric circulation. Here, we present six East Antarctic ice core records of rBC concentrations and fluxes covering the last two centuries with approximately annual resolution (cal. yr. 1800 to 2000). The ice cores were drilled in disparate regions of the high East Antarctic ice sheet, at different elevations and net snow accumulation rates. Annual rBC concentrations were log-normally distributed and geometric means of annual concentrations ranged from 0.10 to 0.18 mu g kg (super -1) . Average rBC fluxes were determined over the time periods 1800 to 2000 and 1963 to 2000 and ranged from 3.4 to 15.5 mu g m (super -2) a (super -1) and 3.6 to 21.8 mu g m (super -2) a (super -1) , respectively. Geometric mean concentrations spanning 1800 to 2000 increased linearly with elevation at a rate of 0.025 mu g kg (super -1) /500 m. Spectral analysis of the records revealed significant decadal-scale variability, which at several sites was comparable to decadal ENSO variability.

The existence of this microbial community in an environment that excludes any other life forms suggests biological adaptation to high salinity and desiccation stress, and indicates an alternative source of water for life other than rainfall, fog or dew. Here, we show that halite endoliths obtain liquid water through spontaneous capillary condensation at relative humidity (RH) much lower than the deliquescence RH of NaCl. We describe how this condensation could occur inside nano-pores smaller than 100 nm, in a newly characterized halite phase that is intimately associated with the endolithic aggregates. This nano-porous phase helps retain liquid water for long periods of time by preventing its evaporation even in conditions of utmost dryness. Our results explain how life has colonized and adapted to one of the most extreme environments on our planet, expanding the water activity envelope for life on Earth, and broadening the spectrum of possible habitats for life beyond our planet.

In the Southern Hemisphere (SH), rBC is transported in the atmosphere from low- and mid-latitudes to Antarctica and deposited to the polar ice sheet preserving a history of emissions and atmospheric transport. Here, we present two high-resolution Antarctic rBC ice core records drilled from the West Antarctic Ice Sheet divide and Law Dome on the periphery of the East Antarctic ice sheet. Separated by approximately 3500 km, the records span calendar years 1850-2001 and reflect the rBC distribution over the Indian and Pacific ocean sectors of the Southern Ocean. Concentrations of rBC in the ice cores displayed significant variability at annual to decadal time scales, notably in ENSO-QBO and AAO frequency bands. The delay observed between rBC and ENSO variability suggested that ENSO does not directly affect rBC transport, but rather continental hydrology, subsequent fire regimes, and aerosol emissions. From 1850 to 1950, the two ice core records were uncorrelated but were highly correlated from 1950 to 2002 (cross-correlation coefficient at annual resolution: r=0.54, p<0.01) due to a common decrease in rBC variability. The decrease in ice-core rBC from the 1950s to late 1980s displays similarities with inventories of SH rBC grass fires and biofuel emissions, which show reduced emission estimates over that period.

From the MISR data for two optically thick, near-source plumes of the spring 2010 Eyjafjallajokull volcano eruption, we map aerosol optical depth (AOD) gradients and changing aerosol particle types with this algorithm; several days downwind, we identify the occurrence of volcanic ash particles and retrieve AOD, demonstrating the extent and the limits of ash detection and mapping capability with the multi-angle, multi-spectral imaging data. Retrieved volcanic plume AOD and particle microphysical properties are distinct from background values near-source, as well as for over-water cases several days downwind. The results also provide some indication that as they evolve, plume particles brighten, and average particle size decreases. Such detailed mapping offers context for suborbital plume observations having much more limited sampling. The MISR Standard aerosol product identified similar trends in plume properties as the Research algorithm, though with much smaller differences compared to background, and it does not resolve plume structure. Better optical analogs of non-spherical volcanic ash, and coincident suborbital data to validate the satellite retrieval results, are the factors most important for further advancing the remote sensing of volcanic ash plumes from space.

Small- scale laboratory experiments cannot reproduce the conditions near the lunar surface, but provide a unique opportunity to identify and examine several of the physical processes. We study plasma interaction with a magnetic dipole field at an insulating surface in order to understand the effect of crustal magnetic anomalies on the solar wind-lunar surface interaction. In our experiments, electrons are magnetized with gyroradii r smaller than distances from the surface d (r2 cm of annual precipitation. ClO (sub 4) (super -) /ClO (sub 3) (super -) molar ratios were similar for most sites ( approximately 1). In contrast, ClO (sub 4) (super -) exhibited substantial variation in its stable isotopic composition (delta (super 18) O and Delta (super 17) O) with respect to location along the longitudinal transect. In addition, the delta (super 18) O and Delta (super 17) O of O in ClO (sub 4) (super -) were strongly correlated (r (super 2) =0.89). Elevated Delta (super 17) O values indicate ClO (sub 4) (super -) formed largely by O (sub 3) mediated oxidation of Cl, possibly in the stratosphere. However, substantial variation in delta (super 18) O (-25 to -3 per mil) and Delta (super 17) O (+4 to +10 per mil) of ClO (sub 4) (super -) is intriguing given the long salt accumulation times ( approximately 10 (super 6) years). This isotopic variation may indicate some unknown process is controlling deposition over a large area for long time periods, atmospheric ClO (sub 4) (super -) isotopic composition has varied in geologic time, or some surface process (generation or alteration) that varies spatially is affecting the ClO (sub 4) (super -) isotope composition by transformation, exchange, or dilution. Insights from our work are relevant to models of oxyanion production and accumulation in areas with little biologic activity.

In this event, a large dust plume was transported over desert, vegetated, and ocean surfaces. The aim is to identify the differences between current datasets. The satellite instruments considered are AATSR, AIRS, MERIS, MISR, MODIS, OMI, POLDER, and SEVIRI. An interesting aspect is that the different algorithms make use of different instrument characteristics to obtain retrievals over bright surfaces. These include multi-angle approaches (MISR, AATSR), polarisation measurements (POLDER), single-view approaches using solar wavelengths (OMI, MODIS), and the thermal infrared spectral region (SEVIRI, AIRS). Differences between instruments, together with the comparison of different retrieval algorithms applied to measurements from the same instrument, provide a unique insight into the performance and characteristics of the various techniques employed. As well as the intercomparison between different satellite products, the AODs have also been compared to co-located AERONET data. Despite the fact that the agreement between satellite and AERONET AODs is reasonably good for all of the datasets, there are significant differences between them when compared to each other, especially over land. These differences are partially due to differences in the algorithms, such as assumptions about aerosol model and surface properties. However, in this comparison of spatially and temporally averaged data, it is important to note that differences in sampling, related to the actual footprint of each instrument on the heterogeneous aerosol field, cloud identification and the quality control flags of each dataset can be an important issue.

This experimental study determined the stable Fe isotopic exchange and fractionation factor between a (super 57) Fe-enriched aqueous Fe(II) and an isotopically "normal" smectite SWa-1 (iron oxide impurities stripped off by purification) using a three-isotope method. Leaching of solid with 0.5 M HCl for 0.5 hr, following separation with aqueous Fe(II) at different time points, yielded mostly Fe(II) in extract 1 and subsequent leaching with 0.5 M HCl for 24 hrs yielded mostly Fe(III) in extract 2. Isotopic exchange between different components was monitored by changes in their delta (super 57/56) Fe values. Isotopic exchange was limited between aqueous Fe(II) and bulk smectite. When excluding bulk smectite from the system, however, about 90% of exchange was achieved between aqueous Fe(II) and extract 1 (a weakly sorbed component) in the beginning of the experiments and leveled off with time, suggesting a steady-state condition was reached early on in the experiments between aqueous Fe and extract 1. Fraction of isotopic exchange (F) reached approximately 50% between aqueous Fe(II) and extract 2. The equilibrium fractionation factor between aqueous Fe(II) and extract 2 has been determined to be approximately -2.4ppm (below figure represents one of the duplicate experiments). Extract 2 could be an iron oxide phase as observed during electron transfer between aqueous Fe(II) and smectite and the mineralogy nature of extract 2 will be further identified using Mossbauer spectra. Nevertheless, the equilibrium Fe isotope fractionation between aqueous Fe(II) and smectite, driven by redox changes, has important implications for understanding redox processes in subsurface environments that is enriched in ferrous iron and clay minerals.

The hematite-bearing 3.4 Ga Marble Bar Chert (MBC) at Marble Bar area of the Pilbara Craton, NW Australia, has been used to argue that Earth's early atmosphere contained significant amounts of oxygen. We measured Fe and U-Th-Pb isotope composition of the MBC samples. Our results indicate that the Marble Bar Chert was deposited from a Fe-rich, but U-poor ocean. The delta (super 56) Fe values of hematite in MBC range between 1.71 ppm and 2.63 ppm, which are the most positive delta (super 56) Fe dataset that has ever been reported from natural rocks (Figure 1). Given that hydrothermal sources of aqueous Fe (super 2+) should have had a delta (super 56) Fe value of around 0 ppm, and that Fe isotope fractionation between hydrous ferric oxides and aqueous Fe (super 2+) is approximately 3-4 ppm, the high delta (super 56) Fe values of hematite in MBC requires partial oxidation of aqueous Fe (super 2+) . This suggests that the oxidant was extremely limited and the main body of ocean water was reduced and rich in Fe (super 2+) . In addition, U concentrations of the MBC samples are over one order of magnitude lower than those of Phanerozoic cherts, indicating lower U content of Archean ocean water than modern ocean water. Moreover, U-Th-Pb isotope analysis shows that the MBC samples has actually undergone U addition during the Phanerozoic, which further attests to low U contents during deposition at 3.4 Ga. This indicates low O (sub 2) levels in Archean atmosphere.

Ecosystem models predict that modest fluxes of methane into reducing atmospheres would result in high concentrations [1], while models of the evolution of atmospheric redox on the early Earth suggest important roles for methane associated with the rise of oxygen [2, 3]. Here, we expand previous photochemical modeling efforts [3, 4] by linking changes in methane concentration to observable geochemical signatures. In a suite of reducing model atmospheres, we increase concentrations of methane until an organic haze forms. Using particles which scatter using both classical Mie physics as well as newly postulated fractal scattering behavior [5], we find that the Archean atmosphere would exhibit bi-stability between a "clear skies" case and one with a thin organic haze. The photochemical modeling further demonstrates that the presence of the thin organic haze would significantly affect the fractionation of minor isotopes of sulfur (mass-independent fractionation of sulfur or S-MIF) by both UV opacity effects and by changing the redox chemistry of S species in the atmosphere. The prediction of an Earth system with correlated changes in methane concentration and variations in S-MIF is evident in new data from the Campbellrand-Malmani platform of South Africa [6], which indicate multiple appearances of organic haze due to a methanogen-driven high CH (sub 4) :CO (sub 2) ratios [4] in the late Neoarchean. These combined results provide stronger evidence for a role for methane in the Neoarchean atmosphere, and support arguments that the Great Oxidation Event may have been related to the the disappearance of a large biological flux of methane [3].

Humans can be directly exposed to toxic substances by inhalation of air dust or indirectly through food chain or by consumption of local water for drinking, cooking, personal hygiene and recreational purposes. Chronic medical problems related to geochemical characteristics of the environment can also be caused by chronic deficit of chemical elements essential for humans. In this paper we will present several applications of the GIS and statistical methods for relating the geographical distribution of diseases with geochemical characteristics of the environment. In addition, we are presenting methods applied for distinguishing natural distribution of elements from anthropogenic contribution, which is important information for establishing protective measures necessary for decreasing the health risk.

Laser desorption provides complementary information to that obtained via the more ubiquitous methods like pyrolysis GC-MS and EGA because it provides molecular information without the need for sample heating. It is also well suited to space flight missions due to the relative ease (or complete lack) of sample preparation. Many mass analyzers have been used in previous missions, such as time-of-flight and quadrupole mass spectrometers, but ion traps in particular have the potential to operate at higher pressures with lower power requirements. One such space flight mission in the development phase is the Mars Organic Molecule Analyzer (MOMA), aboard the joint NASA/ESA rover ExoMars set to launch in 2018. There, Martian soil core samples from a depth of approximately 2 meters will be interrogated by either pyrolysis gas chromatography or laser desorption mass spectrometry in ambient atmospheric conditions. The mass analyzer is a linear ion trap, capable of providing chemical structural analysis via tandem mass spectrometry (MS/MS). A similar mass spectrometer can also be used for analysis of atmospheric particulates, if collected or concentrated properly. Potential applications could include the analysis of Titan's atmospheric components or deposited organic material on the surface. To better understand the instrumental response to Titan-like aerosols, a series of aerosol analogs have been generated via far-UV irradiation of relevant Titan precursors. Aerosols are collected and deposited onto a sample plate interfaced to a commercial version of the MOMA instrument (Thermo MALDI LTQXL). By exploring different aerosol precursors, we are able to test sensitivity of the instrument to different chemical characteristics of the aerosol, including pure hydrocarbons, nitrogen-containing compounds, and large aromatic structures. We will present mass spectrometric results for the range of synthesized analog aerosols; for example, we will compare the spectra of benzene-sourced aerosol to those sourced from the nitrogen-heteroatom equivalent pyridine. These results will highlight the compatibility of the laser desorption method to give abundant molecular and fragment ions for these classes of compounds. Further, the results from the commercial instrument will be compared to analyses utilizing the prototype MOMA instrument, currently in development.

Many atmospheric model studies assume spatially homogeneous total iron content at dust sources, typically 3.5% by mass. Moreover, as iron oxides and hydroxides are comprised of more than 50% iron by mass, models usually consider them as the main suppliers of dissolved iron resulting from dust deposition. A recent experiment has shown a large contribution by clays--their low iron content offset by their large solubility--to the total dissolved iron from dust samples. This and other studies suggest the need for explicit representation of individual minerals in dust-climate models in order to improve our understanding of the atmospheric iron cycle and iron deposition as an input to ocean biological productivity. We have implemented prognostic budgets of separate mineral types into an Earth System Model: GISS/ModelE. Each mineral type (composed of iron and/or other elements) is separately transported and modified within the atmosphere. Spatially-dependent concentrations of illite, kaolinite, smectite, calcite, quartz, feldspar, iron (hydr)oxide, and gypsum are predicted by the model based on an updating of the source mineralogy proposed in the seminal work of. We use downwind observations to constrain the mineral content of aerosols leaving the source. We evaluate model results against global observations of mineral aerosols with emphasis on multiyear measurements of size-segregated dust elemental composition at the Izana Observatory (Tenerife, Canary Islands), situated downwind of important North African dust sources. We highlight the strengths and limitations of the source prescription of and propose new strategies to represent mineral tracers in dust models.

Direct consequences have been observed on the increasing Arctic river flow and a large amount of organic carbon sequestered in soils at high latitudes since the last glacial maximum can be expected to be delivered to the Arctic Ocean during the coming decade. Monitoring the fluxes and fate of this terrigenous organic carbon is problematic in such sparsely populated regions unless remote sensing techniques can be developed and proved to be operational. The main objective of this study is to develop an ocean colour algorithm to operationally monitor dynamics of suspended particulate matter (SPM) on the Mackenzie River continental shelf (Canadian Arctic Ocean) using satellite imagery. The water optical properties are documented across the study area and related to concentrations of SPM and particulate organic carbon (POC). Robust SPM and POC:SPM proxies are identified, such as the light backscattering and attenuation coefficients, and relationships are established between these optical and biogeochemical parameters. Following a semi-analytical approach, a regional SPM quantification relationship is obtained for the inversion of the water reflectance signal into SPM concentration. This relationship is reproduced based on independent field optical measurements. It is successfully applied to a selection of MODIS satellite data which allow estimating fluxes at the river mouth and monitoring the extension and dynamics of the Mackenzie River surface plume in 2009, 2010 and 2011. Good agreement is obtained with field observations representative of the whole water column in the river delta zone where terrigenous SPM is mainly constrained (out of short periods of maximum river outflow). Most of the seaward export of SPM is observed to occur within the west side of the river mouth. Future work will require the validation of the developed SPM regional algorithm based on match-ups with field measurements, then the routine application to ocean colour satellite data in order to better estimate the fluxes and fate of SPM and POC delivered by the Mackenzie River to the Arctic Ocean.

AN - 1507181619; 2014-017485 AB - The Great Oxidiation Event (GOE) was an increase in O (sub 2) levels from <1 ppm to 0.2-2% at approximately 2.45-2.22 Ga. How it happened is still debatable. One idea is that the GOE ensued when oxygenic photosynthesis originated. But evidence suggests that oxygenic photosynthesis considerably predates the GOE, e.g., from redox-sensitive metals, stromatolites, organic carbon derived from methanotrophs, and biomarkers. Instead, reductants plausibly cleared the late Archean air of O (sub 2) . Most hypotheses explain the delay by suggesting that O (sub 2) sources took time to overwhelm O (sub 2) sinks. The O (sub 2) source, organic carbon (C (sub org) ) burial, may have slowly increased to cause the GOE. But the noisy delta (super 13) C record may not allow for such a change, while the decomposition of C (sub org) in the approximately 10 (super 8) yr geologic cycle destroys O (sub 2) gains from C (sub org) burial. Also, inventories show that continents have excess oxygen, not excess C (sub org) . An alternative is that O (sub 2) could have risen if the sink from volcanic reducing gases declined. Many ideas have focused on a shift in mantle or seafloor reductant fluxes, including appeals to changes in subaerial vs. submarine gases. But for this idea to work, the surface still has to export net reductant to the mantle, which is itself initially reduced. Oxidation of other planetary or satellite surfaces is universally attributed to the escape of hydrogen. This accounts for Mars' redness and tenuous O (sub 2) atmospheres on Europa, Ganymede, and Rhea. Earth's pre-GOE atmosphere was enriched in CH (sub 4) and H (sub 2) and prone to hydrogen escape at rates that must have produced large irreversible oxidation. If continents grew until approximately 3-2 Ga, they would have accumulated excess oxygen in minerals. Atmospheric O (sub 2) would have become more stable by application of Le Chatelier's principle to the surface environment of the whole Earth. Conclusions: Overall, rapid escape of hydrogen to space from the pre-GOE atmosphere should have gradually oxidized the Earth, accompanied by falling atmospheric CH (sub 4) levels. The disappearance of S isotope mass independent fractionation at 2.4 Ga is best explained by the collapse of CH (sub 4) as marine sulfate levels grew and methanotrophy kicked in. The "tipping point" for flooding the atmosphere with O (sub 2) was when the flux of O (sub 2) from the burial of organic carbon exceeded O (sub 2) losses. Glaciations during 2.45-2.22 Ga suggest oscillations in atmospheric composition until a new O (sub 2) balance with oxidative weathering was established.

Interpretations of Fe isotope fractionations in Archean and Paleoproterozoic banded iron formations (BIFs), shales, and carbonates suggest a role for biological processes (bacterial dissimilatory iron reduction (DIR) and anoxygenic photosynthetic iron oxidation (APIO)] and abiological processes (oxidation by free O (sub 2) ). Measurements of rock powders micromilled from individual magnetite layers and of individual magnetite grains analyzed by femtosecond laser ablation ICP-MS (fs-LA-ICP-MS) from BIFs of the 3.7-3.8 Ga Isua greenstone belt reveal a consistently narrow range of non-zero delta (super 56) Fe values. Analyses by fs-LA-ICP-MS allow for precise and accurate micron-scale analyses without the orientation effects associated with secondary ion mass spectrometry analyses of magnetite. Magnetite delta (super 56) Fe values range from +0.4ppm to +1.1ppm among different bands, but within individual layers magnetites are homogenous. In buld samples, delta (super 56) Fe and SiO (sub 2) concentration are negatively correlated, whereas delta (super 56) Fe and total Fe concentrations are positively correlated, reflecting mixtures between magnetite and Fe silicate. A simple mixing model between a low-delta (super 56) Fe component (Fe silicate) and a high-delta (super 56) Fe component (magnetite) can explain the range in Fe isotope compositions of the micromilled rock powders. Although these BIFs have been metamorphosed to greenschist- to amphibolite-facies, the isotopic heterogeneity observed on both scales suggests that the Fe isotope compositions reflect primary, low-temperature sedimentary values. The positive delta (super 56) Fe values measured from the Isua magnetites are best explained by deposition of Fe-oxides produced by partial oxidation of Fe(II)-rich ocean water either by free O (sub 2) or APIO. Comparison of the Fe isotope data from the Isua BIFs with those from the 2.5 Ga BIFs from the Hamersley and Transvaal Basins suggests a striking difference in Fe sources and pathways. The Neoarchean magnetite facies BIFs of Australia and South Africa have delta (super 56) Fe values that range from -1.2 to +1.2 ppm and are on average significantly lower than those reported here from the Isua BIFs. Such a range suggests a role for DIR, the most likely means by which to produce large masses of negatively fractionated Fe. The absence of low delta (super 56) Fe values in the Isua BIFs may indicate formation prior to the evolution of DIR or in an environment that excluded this metabolism.

Humankind's limited exploration experience with the Apollo Program indicates that exposure to dust will be unavoidable. Therefore, NASA must assess potential toxicity and recommend appropriate mitigation measures to ensure that explorers are adequately protected. Visual acuity is critical during exploration activities and operations aboard spacecraft. Therefore, the present research was performed to ascertain the ocular toxicity of authentic lunar dust. Methods: Small (mean particle diameter = 2.9 plus or minus 1.0 [mu]m), reactive lunar dust particles were produced by grinding bulk dust under ultrapure nitrogen conditions. Chemical reactivity and cytotoxicity testing were performed using the commercially available EpiOcular super(TM) assay. Subsequent in vivo Draize testing utilized a larger size fraction of unground lunar dust that is more relevant to ocular exposures (particles <120 [mu]m; median particle diameter = 50.9 plus or minus 19.8 [mu]m). Results: In vitro testing indicated minimal irritancy potential based on the time required to reduce cell viability by 50% (ET50). Follow-up testing using the Draize standard protocol confirmed that the lunar dust was minimally irritating. Minor irritation of the upper eyelids was noted at the 1-hour observation point, but these effects resolved within 24 hours. In addition, no corneal scratching was observed using fluorescein stain. Conclusions: Low-titanium mare lunar dust is minimally irritating to the eyes and is considered a nuisance dust for ocular exposure. No special precautions are recommended to protect against ocular exposures, but fully shielded goggles may be used if dust becomes a nuisance.

Ancient methane seeps are recognized by endemic seep fauna and/or lithological, textural evidence of the passage and metabolism of methane bearing fluids. Highly (super 13) C-depleted carbonates (10 mM levels in the Late Devonian/Early Carboniferous, corresponding with the rise of land plants [5, 6]. Implications for Ediacaran ocean [SO (sub 4) (super 2-) ] will also be discussed. Our investigation shows that secular variations in ocean [SO (sub 4) (super 2-) ] provide a plausible explanation for the temporal distribution and delta (super 13) C of seep carbonates and highlight the need to refine criteria for recognizing ancient methane seep ecosystems.

Yet, the degradation of organic molecules by cosmic ray irradiation on Mars is often ignored. We calculate the radiation dose accumulation rates from solar and galactic cosmic rays at various depths in the shallow Martian subsurface. We demonstrate that a 1-billion-year outcrop on Mars accumulates the dosage of approximately 500 MGy in the top 0-2 cm and approximately 50 MGy at 5-10 cm depths. We show that the preservation of ancient complex organic molecules in the shallow ( approximately 10 cm depth) subsurface of rocks could be highly problematic if the exposure age of a geologic outcrop would exceed 300 Myr. We demonstrate that more simple organic molecules with masses approximately 100 amu should have a good chance to survive in the shallow subsurface of rocks. Implications to the sampling strategy for the oncoming Martian missions are discussed.

We evaluate recent mass loss by mapping elevation changes between 2006 and 2010/11 using differencing of digital elevation models (DEMs). The measurement accuracy of these elevation changes is confirmed by a 'null test', subtracting DEMs acquired within a few weeks. The overall 2006-2010/11 mass loss rate (9.0 + or - 2.1 Gt a (super -1) ) is similar to the 2001/02-2006 rate (8.8?+ or -1.6 Gt a (super -1) ), derived using DEM differencing and laser altimetry. This unchanged overall loss masks a varying pattern of thinning and ice loss for individual glacier basins. On Crane Glacier, the thinning pulse, initially greatest near the calving front, is now broadening and migrating upstream. The largest losses are now observed for the Hektoria/Green glacier basin, having increased by 33% since 2006. Our method has enabled us to resolve large residual uncertainties in the Larsen B sector and confirm its state of ongoing rapid mass loss.

Basal crevasses, large-scale structural features within ice shelves, may have contributed to this mechanism in three important ways: i) the shelf surface deforms due to modified buoyancy and gravitational forces above the basal crevasse, creating >10 m deep compressional surface depressions where meltwater can collect, ii) bending stresses from the modified shape drive surface crevassing, with crevasses reaching 40 m in width, on the flanks of the basal-crevasse-induced trough and iii) the ice thickness is substantially reduced, thereby minimizing the propagation distance before a full-thickness rift is created. We examine a basal crevasse (4.5 km in length, approximately 230 m in height), and the corresponding surface features, in the Cabinet Inlet sector of the Larsen C Ice Shelf using a combination of high-resolution (0.5 m) satellite imagery, kinematic GPS and in situ ground penetrating radar. We discuss how basal crevasses may have contributed to the breakup of the Larsen B Ice Shelf by directly controlling the location of meltwater ponding and highlight the presence of similar features on the Amery and Getz Ice Shelves with high-resolution imagery.

Hydrous silicate melt is produced at the solidi at 3-4 GPa whereas Na-K-rich carbonatite is produced at the solidi at > or =5 GPa for both starting compositions. At > or =5 GPa and 1050 degrees C, immiscible carbonate and silicate melts appear with carbonate melt forming isolated pockets embedded in silicate melt. Application of our data to Nicaraguan slab suggests that sediment melting may not occur at sub-arc depth ( approximately 170 km) but carbonatite production can occur atop slab or by diapiric rise of carbonated-silicate melange zone to the mantle wedge at approximately 200-250 km depth. Flux of carbonatite to shallower arc-source can explain the geochemistry of Nicaraguan primary magma (low SiO (sub 2) and high CaO, Ba/La). Comparison of carbonate-silicate melt immiscibility field with mantle wedge thermal structure suggests that carbonatite might temporally be trapped in viscous silicate melt, and contribute to seismic low-velocity zone at deep mantle wedge of Nicaragua.

While the primary causes of these droughts are still debated, it has been speculated that they may be linked to extensive deforestation associated with high population densities during these intervals. Here we show that pre-Columbian deforestation would have biased the climate in Mesoamerica towards a drier mean state, amplifying drought in the region. In climate model simulations using a pre-Columbian land cover reconstruction, annual precipitation decreases by 5%-15% throughout southern Mexico and the Yucatan compared to simulations using either natural forest cover or forest regrowth associated with population declines after 1500 C.E. These changes are driven primarily by large reductions (10%-20%) in precipitation during the late summer wet season (August-September). When compared to precipitation changes estimated to have occurred during the Maya collapse, our results suggest that deforestation could account for up to sixty percent of the mean drying during this interval. Many regions previously deforested in the pre-Columbian era are now under dense forest cover, indicating potential future climate impacts should tropical deforestation of these areas accelerate.

As far as we know, our Hybrid Coordinate Ocean Model (HYCOM) simulations shown here and in an earlier paper are the only published high-resolution global simulations to contain barotropic tides, internal tides, the general circulation, and mesoscale eddies concurrently. Comparing the model barotropic tide with a global data-assimilative shallow water tide model shows that the global tidal elevation differences are approximately evenly split between discrepancies in tidal amplitude and phase. Both the model and observations show strong generation of internal tides at a limited number of "hot spot" regions with propagation of beams of energy for thousands of kilometers away from the sources. The model internal tidal amplitudes compare well with observations near these energetic tidal regions. Averaged over these regions, the model and observation internal tide amplitude estimates agree to approximately 15% for the four largest semidiurnal constituents and 23% for the four largest diurnal constituents. Away from the hot spots, the comparison between the model and altimetric amplitude is not as good due, in part, to two problems, errors in the model barotropic tides and overestimation of the altimetric tides in regions of strong mesoscale eddy activity. Examining the general energy distribution of the simulated internal tide is an important first step in the evaluation of internal tides in HYCOM.

Assimilation was conducted in an energy-limited environment and a water-limited environment. Modeling uncertainty was prescribed to weather inputs, soil parameters and initial conditions, and cultivar parameters and through perturbations to model state transition equations. The ensemble Kalman filter and the sequential importance resampling filter were tested for the ability to attenuate effects of these types of uncertainty on yield estimates. LAI and theta observations were synthesized according to characteristics of existing remote sensing data, and effects of observation error were tested. Results indicate that the potential for assimilation to improve end-of-season yield estimates is low. Limitations are due to a lack of root zone soil moisture information, error in LAI observations, and a lack of correlation between leaf and grain growth.

The removal of these positive anomalies by late accretion of a chondritic veneer can be quickly refuted by comparison with lunar breccia siderophile element abundances which contain too low an accreted meteoritic component to affect a mantle-wide change in W isotope composition. Here, we present two sets of alternative models to interpret this incredible finding. Post core-formation mantle: Because D(metal-silicate) for W diminishes with increasing depth, the deep mantle has a higher W abundance, and a lower Hf/W ratio and consequently evolves a negative anomaly in epsilon (super 182) W while the upper mantle evolves a positive epsilon (super 182) W. Subsequent solid-state convection (4.55-2.8 Ga) mixes away the complementary epsilon (super 182) W anomalies. This set of models predicts that the complementary negative anomalies in epsilon (super 182) W should eventually be discovered in ancient magmatic rocks. Hadean melting models: Tungsten is significantly more incompatible (like U, Th and Ba) than Hf, the latter being similar in compatibility to Nd and Sm. Our results show that extraction of low-degree partial melts (<2%) leaving a Hadean depleted mantle that can have Sm/Nd approximately 20% higher than chondrites also creates a f (sub Hf/W) approximately 2-3, sufficient to generate the anomalies observed in the first 100 Ma of Earth history. These models increase Hf/W and Sm/Nd ratios in a correlated fashion explaining the tendency of positive anomalies of epsilon (super 182) W to occur in rocks with positive epsilon (super 142) Nd. Recycling of the complementary Hadean crust would result in negative anomalies, while partitioning of W into an enriched "hidden reservoir" would not. Evidence from Hadean zircons indicates crust was preserved from 4.4 Ga onwards, too late to constrain epsilon (super 182) W anomalies which are more challenging to create after the first 100 Ma. (super 142) Nd anomalies indicate a melting event around 35-75 Ma after solar system formation, the upper end of which is consistent with our models of Hf/W fractionation that also yield a depleted mantle composition consistent with DMM. The presence of epsilon (super 182) W anomalies in the Hadean mantle complicates the search for W isotopic evidence of core-mantle interaction, now predicted to be epsilon (super 182) W approximately -0.1.

The available water samples cover the period from September 8th 2011 to January 11th 2012. The pre-earthquake anomaly is characterized by a slight but clear increase in Ca (super 2+) , Mg (super 2+) , K (super +) and Cl (super -) contents and decrease in Na (super +) and SO (sub 4) (super 2-) contents compared to the background. Post-seismic samples show decreasing trends in Ca (super 2+) , Mg (super 2+) , K (super +) and Cl (super -) and increasing trends in Na (super +) and SO (sub 4) (super 2-) . All ion concentrations reach stability approximately one month after the earthquake. These results indicate that spring water chemical anomalies may be monitored as potential geochemical pre-earthquake indicators.

Here, using an ensemble of previously published model results, making up "EoMIP" - the Eocene Modelling Intercomparison Project--and syntheses of early Eocene terrestrial and sea surface temperature data, we present a self-consistent inter-model and model-data comparison. This shows that the previous modelling studies exhibit a very wide inter-model variability, but that at high CO (sub 2) , there is good agreement between models and data for this period, particularly if possible seasonal biases in some of the proxies are considered. An energy balance analysis explores the reasons for the differences between the model results, and suggests that differences in surface albedo feedbacks, water vapour and lapse rate feedbacks, and prescribed aerosol loading are the dominant cause for the different results seen in the models, rather than inconsistencies in other prescribed boundary conditions or differences in cloud feedbacks. The CO (sub 2) level which would give optimal early Eocene model-data agreement, based on those models which have carried out simulations with more than one CO (sub 2) level, is in the range of 2500 ppmv to 6500 ppmv. Given the spread of model results, tighter bounds on proxy estimates of atmospheric CO (sub 2) and temperature during this time period will allow a quantitative assessment of the skill of the models at simulating warm climates. If it is the case that a model which gives a good simulation of the Eocene will also give a good simulation of the future, then such an assessment could be used to produce metrics for weighting future climate predictions.

The first simulation uses BEDMAP bathymetry under the Pine Island ice shelf, and the second simulation uses NASA IceBridge-derived bathymetry. The IceBridge data reveal the existence of a trough from the ice-shelf edge to the grounding line, enabling warm Circumpolar Deep Water to penetrate to the grounding line, leading to higher melt rates than previously estimated. The mean melt rate for the simulation with NASA IceBridge data is 28 m a (super -1) , much higher than previous model estimates but closer to estimates from remote sensing. Although the mean melt rate is 25% higher than in the simulation with BEDMAP bathymetry, the temporal evolution remains unchanged between the two simulations. This indicates that temporal variability of melting is mostly driven by processes outside the cavity. Spatial melt rate patterns of BEDMAP and IceBridge simulations differ significantly, with the latter in closer agreement with satellite-derived melt rate estimates of approximately 50 m a (super -1) near the grounding line. Our simulations confirm that knowledge of the cavity shape and its time evolution are essential to accurately capture basal mass loss of Antarctic ice shelves.

Likewise, > 3.9 Ga zircons from samples of lunar impact breccias provide unique evidence for the pre-3.9 Ga history of the Moon. Cogenetic zircons in small igneous rock fragments in lunar breccias provide direct information on the age of lunar igneous events, which in some cases, can be related to impacts. Secondary disturbances of the U-Pb systems of lunar zircons can also provide evidence for the age of impacts. However, in general, lunar zircons occur as separate broken grains in the matrices of impact breccias or in the lunar regolith. Likewise, detrital zircons in metasedimentary rocks from the Narryer Terrane have been separated from their original source rocks which have never been located. The age distributions of zircons from lunar breccias and the Narryer metasedimentary rocks show characteristic peaks that indicate episodes of igneous activity.

Directly beyond the ejecta layer drops to 500km. This sudden decrease is also observed at Martian ejecta blankets where the subsurface probably contains water. The ejecta breccia is initially mixed with over pressurized water providing lubrication and low internal friction. The friction increases exponentially over a critical threshold when the water escapes, causing the ejecta blanket to suddenly stop moving. Ejecta beyond >500km consists of ballistically emplaced impact glass and accretionary silicate and carbonate spherules, decreasing in size from 2cm at 500km to 5000km is continuous and has a constant thickness of 2-3mm and invariably filled with condensates (microkrystites) from the hot fireball vapor. Recently, the K-Pg distal ejecta layer could be traced in north-western Turkey over >150km, remaining constant in thickness over the entire distance. In Woodside creek and Meadstream (New-Zealand) the microkrystites were identified in the same amount and size as Agost and Petriccio. Apparently, there is no gradient in distribution of size and amount of microkystites over the entire globe. This suggests that on average a microkrystite orbits the Earth several times.

These flows are thought to be mixtures of clasts and melted material that are emplaced during the late stages of impact crater formation. Lunar impact melts have been primarily studied at optical wavelengths, but complementary information can be obtained by observing impact melts at radar wavelengths. Radar data is sensitive to surface and subsurface roughness, and thus can highlight these features even when they are not easily seen in optical data. Impact melts have been identified in radar data on the lunar near side, but they have yet to be studied in depth on the lunar far side, given the lack of global radar data prior to the launch of NASA's Mini-RF instrument on the Lunar Reconnaissance Orbiter (LRO). We have therefore under taken a global mapping project to identify impact melt flows in the Mini-RF data set. We seek to use this data to determine how the emplacement of melt deposits is influenced by pre-existing topography and impact direction. We have thus far discovered ten new impact melt flow candidates. These melt flows extend further from the crater rim than previously thought possible, and include craters as small as 3 km in diameter. Of the candidate flows, 50% coincide with the direction of rim crest flow, and 20% coincide with the downrange direction of impact. This suggests that for many of these candidates, pre-existing topography plays an important role in final melt flow morphology.

The simulated aerosol optical thickness and transport of the volcanic cloud are in good agreement with observations of the actual Pinatubo eruption from the Stratospheric Aerosol and Gas Experiment II (SAGE II) and the Advanced Very High Resolution Radiometer (AVHRR) and with vertical profiles of sulfur dioxide observed by the Microwave Limb Sounder (MLS). We tested the importance of initial conditions corresponding to the specific meteorological situation at the time of the eruption by comparing results when GEOS-5 is initialized using Modern Era Retrospective Analyses for Research and Applications (MERRA) reanalysis fields with results when it is initialized from an existing model run. We found no significant difference in the transport of the cloud. We show how the inclusion of the interaction between volcanic sulfate aerosol and radiation is essential for a reliable simulation of the transport of the volcanic cloud. The absorption of longwave radiation by the volcanic sulfate largely induces the rising of the volcanic cloud up to the middle stratosphere and the divergent motion from the latitude of the eruption to the tropics. Our simulations indicate that the cloud is transported to the Northern Hemisphere through a lower stratospheric pathway and to middle and high latitudes of the Southern Hemisphere through a middle stratospheric pathway, centered at about 30 hPa. The direction of the middle stratospheric pathway depends on the season of the eruption.

Etna, located in eastern Sicily, has produced a great number of explosive eruptions. Volcanic plumes have risen to several km above sea level and created problems for aviation and the communities living near the volcano. A reduction of hazards may be accomplished using remote sensing techniques to evaluate important features of volcanic plumes. Since 2000, the Multiangle Imaging SpectroRadiometer (MISR) on board NASA's Terra spacecraft has been extensively used to study aerosol dispersal and to extract the three-dimensional structure of plumes coming from anthropogenic or natural sources, including volcanoes. In the present work, MISR data from several explosive events occurring at Etna are analyzed using a program named MINX (MISR INteractive eXplorer). MINX uses stereo matching techniques to evaluate the height of the volcanic aerosol with a precision of a few hundred meters, and extracts aerosol properties from the MISR Standard products. We analyzed twenty volcanic plumes produced during the 2000, 2001, 2002-03, 2006 and 2008 Etna eruptions, finding that volcanic aerosol dispersal and column height obtained by this analysis is in good agreement with ground-based observations. MISR aerosol type retrievals: (1) clearly distinguish volcanic plumes that are sulphate and/or water vapor dominated from ash-dominated ones; (2) detect even low concentrations of volcanic ash in the atmosphere; (3) demonstrate that sulphate and/or water vapor dominated plumes consist of smaller-sized particles compared to ash plumes. This work highlights the potential of MISR to detect important volcanic plume characteristics that can be used to constrain the eruption source parameters in volcanic ash dispersion models. Further, the possibility of discriminating sulphate and/or water vapor dominated plumes from ash-dominated ones is important to better understand the atmospheric impact of these plumes.

Several formation mechanisms and environments have been postulated for the amino acids detected in carbonaceous chondrites. As each proposed mechanism utilizes different precursor molecules, the isotopic signatures of the resulting amino acids may indicate the most likely of these pathways. We have applied gas chromatography with mass spectrometry and combustion isotope ratio mass spectrometry to measure the compound-specific C, N, and H stable isotopic ratios of amino acids from seven CM and CR carbonaceous chondrites: CM1/2 Allan Hills (ALH) 83100, CM2 Murchison, CM2 Lewis Cliff (LEW) 90500, CM2 Lonewolf Nunataks (LON) 94101, CR2 Graves Nunataks (GRA) 95229, CR2 Elephant Moraine (EET) 92042, and CR3 Queen Alexandra Range (QUE) 99177. We compare the isotopic compositions of amino acids in these meteorites with predictions of expected isotopic enrichments from potential formation pathways. We observe trends of decreasing delta (super 13) C and increasing delta D with increasing carbon number in the alpha -H, alpha -NH2 amino acids that correspond to predictions made for formation via Strecker-cyanohydrin synthesis. We also observe light delta (super 13) C signatures for beta -alanine, which may indicate either formation via Michael addition or via a pathway that forms primarily small, straight-chain, amine-terminal amino acids (n-omega -amino acids). Higher deuterium enrichments are observed in alpha -methyl amino acids, indicating formation of these amino acids or their precursors in cold interstellar or nebular environments. Finally, individual amino acids are more enriched in deuterium in CR chondrites than in CM chondrites, reflecting different parent-body chemistry.

The impact of a dust particle on a spacecraft produces a plasma cloud whose associated electric field can be detected by on-board electric antennas. For this study we use the electric potential time series recorded by the waveform sampler of the instrument. The high time resolution and long sampling times of this measurement enable us to deduce considerably more information than in previous studies based on the dynamic power spectra provided by the same instrument or by radio instruments onboard other spacecraft. The large detection area compared to conventional dust detectors provides flux data with a better statistics. We show that the dust-generated signals are of two kinds, corresponding to impacts of dust from distinctly different mass ranges. We propose calibration formulas for these signals and show that we are able to use S/WAVES as a dust detector with convincing results both in the nanometer and micrometer size ranges. In the latter, the orbital motion of the spacecraft enables us to distinguish between interstellar and interplanetary dust components. Our measurements cover the mass intervals approximately 10 (super -22) -10 (super -20) kg and approximately 10 (super -17) -5X10 (super -16) kg. The flux of the larger dust agrees with measurements of other instruments on different spacecraft.

However, models for the production and loss of species derived from the lunar regolith through micrometeoroid impact vaporization, sputtering, and photon-stimulated desorption, predict that a host of other species should exist in the lunar exosphere. Assuming that loss processes are limited to ballistic escape, photoionization, and recycling to the surface, we have computed column abundances and compared them to published upper limits for the Moon. Only for Ca do modeled abundances clearly exceed the available measurements. This result suggests the relevance of some loss processes that were not included in the model, such as the possibility of gas-to-solid phase condensation during micrometeoroid impacts or the formation of stable metallic oxides. Our simulations and the recalculation of efficiencies for resonant light scattering show that models for other species studied are not well constrained by existing measurements. This fact underlines the need for improved remote and in situ measurements of the lunar exosphere such as those planned by the Lunar Atmosphere and Dust Environment Explorer (LADEE) spacecraft. Our simulations of the LADEE neutral mass spectrometer and visible/ultraviolet spectrometer indicate that LADEE measurements promise to provide definitive observations or set stringent upper limits for all regolith-driven exospheric species. We predict that observations by LADEE will constrain assumed model parameters for the exosphere of the Moon.

Aromatic molecules, photolytically active in the ultraviolet, may be important in the formation of the organic aerosol comprising the Titan haze layer even when present at low mixing ratios. Yet there have not been laboratory simulations exploring the impact of these molecules as precursors to Titan's organic aerosol. Observations of Titan by the Cassini Composite Infrared Spectrometer (CIRS) in the far-infrared (far-IR) between 560 and 20 cm (super -1) ( approximately 18 to 500 mu m) have been used to infer the vertical variations of Titan's aerosol from the surface to an altitude of 300 km. Titan's aerosol has several observed emission features which cannot be reporoduced using currently available optical constants from laboratory-generated Titan aerosol analogs, in particular a broad far-IR feature centered approximately at 140 cm (super -1) (71 mu m). There is a need to revisit the infrared spectrum of laboratory-produced aerosol, particularly in the far-IR. We speculate these features may be a blended composite of low-energy vibrations of two-dimensional lattice structures of large molecules, such as PAHs or nitrogenated aromatics. Such structures do not necessarily dominate the composition of analog materials generated from CH (sub 4) and N (sub 2) irradiation. We are performing studies forming aerosol analogs via UV irradiation of several aromatic precursors - with and without nitrogen heteroatoms - to understand how the unique chemical architecture of the products influence observable aerosol characteristics. The optical and chemical properties of the aromatic analog will be compared to those formed from CH (sub 4) /N (sub 2) mixtures, with a focus on the as-yet unidentified far- and mid-IR absorbance features. These studies show that the aerosol formed from aromatic precursors have distinct chemical composition as compared to previously studied analogs, which has implications for the optical properties of Titan's aerosol.

A previous study indicated that the polar-deposit-hosting craters (PDCs) at Mercury's north pole are shallower than craters that lack such deposits. We use data acquired by the Mercury Laser Altimeter on the MESSENGER spacecraft during 11 months of orbital observations to revisit the depths of craters at high northern latitudes on Mercury. We measured the depth and diameter of 537 craters located poleward of 45 degrees N, evaluated the slopes of the northern and southern walls of 30 PDCs, and assessed the floor roughness of 94 craters, including nine PDCs. We find that the PDCs appear to have a fresher crater morphology than the non-PDCs and that the radar-bright material has no detectable influence on crater depths, wall slopes, or floor roughness. The statistical similarity of crater depth-diameter relations for the PDC and non-PDC populations places an upper limit on the thickness of the radar-bright material (<170 m for a crater 11 km in diameter) that can be refined by future detailed analysis. Results of the current study are consistent with the view that the radar-bright material constitutes a relatively thin layer emplaced preferentially in comparatively young craters.

We use a Monte Carlo model of the exosphere to track the trajectories of calcium atoms ejected from the surface until they are photoionized, escape from the system, or stick to the surface. This model permits an exploration of exospheric source processes and interactions among neutral atoms, solar radiation, and the planetary surface. The MASCS data have suggested that a persistent, high-energy source of calcium that was enhanced in the dawn, equatorial region of Mercury was active during MESSENGER's three flybys of Mercury and during the first seven orbits for which MASCS obtained data. The total Ca source rate from the surface varied between 1.2 X 10 (super 23) and 2.6 X 10 (super 23) Ca atoms s (super -1) , if its temperature was 50,000 K. The origin of this high-energy, asymmetric source is unknown, although from this limited data set it does not appear to be consistent with micrometeoroid impact vaporization, ion sputtering, electron-stimulated desorption, or vaporization at dawn of material trapped on the cold nightside.

Such deposits are rare, but have been observed in craters as small as 170 m diameter. The melt occurs as well-defined pools on the crater floor, as well as veneers on the inner crater wall and stringers of material extending over the rim and away from the crater. Model calculations indicate that the amount of melt formed in craters 100-2000 m diameter would amount to a few to approximately 10 (super 6) m (super 3) , representing <1% of the crater volume. Thus, significant, visible impact melt deposits would not be expected in such small craters as most of the melt material that was formed would be ejected. Variations in the properties of the projectile or the target cannot account for the amount of observed melt; the amount of melt produced is largely insensitive to such variations. Rather, we suggest that these small melt-containing craters represent near-vertical impacts in which the axes of melting and melt motion are essentially straight down, toward the base of the transient cavity. For a given event energy under vertical impact conditions, the volume of melt produced would be greater than in an oblique impact and the momentum of the material would be directed vertically downward with minimal lateral momentum such that most of the melt is retained within the crater interior. Since vertical impacts are relatively rare, such small craters with visible, interior melt deposits are rare. While we focus here on the highlands, such craters also occur on the maria.

Less clear has been the morphometric characteristics of these landforms due to their large size and the lack of global high-resolution topography data. We use data from the Lunar Orbiter Laser Altimeter (LOLA) instrument onboard the Lunar Reconnaissance Orbiter (LRO) spacecraft to derive the morphometric characteristics of impact basins on the Moon, assess the trends, and interpret the processes involved in the observed morphologic transitions. We first developed a new technique for measuring and calculating the geometric/morphometric properties of impact basins on the Moon. This new method meets a number of criteria that are important for consideration in any topographic analysis of crater landforms (e.g., multiple data points, complete range of azimuths, systematic, reproducible analysis techniques, avoiding effects of post-event processes, robustness with respect to the statistical techniques). The resulting data more completely capture the azimuthal variation in topography that is characteristic of large impact structures. These new calculations extend the well-defined geometric trends for simple and complex craters out to basin-sized structures. Several new geometric trends for peak-ring basins are observed. Basin depth: A factor of two reduction in the depth to diameter (d/D (sub r) ) ratio in the transition from complex craters to peak-ring basins may be characterized by a steeper trend than known previously. The d/D (sub r) ratio for peak-ring basins decreases with rim-crest diameter, which may be due to a non-proportional change in excavation cavity growth or scaling, as may occur in the simple to complex transition, or increased magnitude of floor uplift associated with peak-ring formation. Wall height, width, and slope: Wall height and width increase with increasing rim-crest diameter, while wall slope decreases; decreasing ratios of wall width to radius and wall height to depth may reflect burial of wall slump block toes by impact melt redistribution during transient cavity collapse. Melt expulsion from the central basin may help to explain the observed increase in floor height to depth ratio; such central depressions are seen within the largest peak-ring basins. Peak-ring height: Heights of peak rings increase with increasing rim-crest diameter (similar to central peak heights in complex craters); peak-ring height to basin depth ratio also increases, suggesting that floor uplift is even larger in magnitude in the largest peak-ring basins. No correlation is found between peak-ring elevation and distance to the rim wall within a single basin, suggesting that rim-wall slumping does not control the topography of peak rings. Offset of peak rings: Peak rings often show minor offset from the basin center. Enhancement in peak-ring elevation in the direction of offset is generally not observed, although this could be a function of magnitude of offset. Basin volume: Volumes of peak-ring basins are about 40% smaller than the volumes predicted by geophysical estimates of the dimensions of corresponding excavation cavities. This difference indicates that collapse of the transient cavity must result in large inward and upward translations of the cavity floor. These new observations of geometric/morphometric properties of protobasins and peak-ring basins place some constraints on the processes controlling the onset and formation of interior landforms in peak-ring basins. Comparisons of the geometric trends of the inner rings of Orientale basin with those of peak-ring basins are generally consistent with a mega-terrace model for the formation of multi-ring basins.

Carbonaceous meteorites are known to contain a wealth of indigenous organic molecules, including amino acids, which suggests that these meteorites could have been an important source of prebiotic organic material during the origins of life on Earth and possibly elsewhere. We report the detection of extraterrestrial amino acids in thermally altered type 3 CV and CO carbonaceous chondrites and ureilites recovered from Antarctica. The amino acid concentrations of the thirteen Antarctic meteorites ranged from 300 to 3200 parts-per-billion (ppb), generally much less abundant than in amino acid-rich CI, CM, and CR carbonaceous chondrites that experienced much lower temperature aqueous alteration on their parent bodies. In contrast to low-temperature aqueously altered meteorites that show complete structural diversity in amino acids formed predominantly by Strecker-cyanohydrin synthesis, the thermally altered meteorites studied here are dominated by small, straight-chain, amine terminal (n-omega -amino) amino acids that are not consistent with Strecker formation. The carbon isotopic ratios of two extraterrestrial n-omega -amino acids measured in one of the CV chondrites (delta (super 13) C approximately -25 ppm) are consistent with (super 13) C-depletions observed previously in hydrocarbons produced by Fischer-Tropsch type reactions. The predominance of n-omega -amino acid isomers in thermally altered meteorites hints at cosmochemical mechanisms for the preferential formation and preservation of a small subset of the possible amino acids.

GCR fluxes remain at the highest levels ever observed during the space age. One of the largest SEP events observed by CRaTER during the LRO mission occurred on June 7, 2011. We compare model predictions by the Earth-Moon-Mars Radiation Environment Module (EMMREM) for both dose rates from GCRs and SEPs during this event with results from CRaTER. We find agreement between these models and the CRaTER dose rates, which together demonstrate the accuracy of EMMREM, and its suitability for a real-time space weather system. We utilize CRaTER to test forecasts made by the Relativistic Electron Alert System for Exploration (REleASE), which successfully predicts the June 7th event. At the maximum CRaTER-observed GCR dose rate ( approximately 11.7 cGy/yr where Gy is a unit indicating energy deposition per unit mass, 1 Gy = 1 J/kg), GCRs deposit approximately 88 eV/molecule in water over 4 billion years, causing significant change in molecular composition and physical structure (e.g., density, color, crystallinity) of water ice, loss of molecular hydrogen, and production of more complex molecules linking carbon and other elements in the irradiated ice. This shows that space weathering by GCRs may be extremely important for chemical evolution of ice on the Moon. Thus, we show comprehensive observations from the CRaTER instrument on the Lunar Reconnaissance Orbiter that characterizes the radiation environment and space weathering on the Moon.

The craters Tycho and Glushko have long melt flows that exhibit variations in radar backscatter and circular polarization ratio along the flow. Comparison with optical imaging reveals that these changes are caused by features commonly seen in terrestrial lava flows, such as rafted plates, pressure ridges, and ponding. Small (<20 km) sized craters also show a large variety of deposits, including melt flows and ponds. Two craters have flow features that may be ejecta flows caused by entrained debris flowing across the surface rather than by melted rock. The circular polarization ratios (CPRs) of the impact melt flows are typically very high; even ponded areas have CPR values between 0.7 and 1.0. This high CPR suggests that deposits that appear smooth in optical imagery may be rough at centimeter- and decimeter- scales. In some places, ponds and flows are visible with no easily discernable source crater. These melt deposits may have come from oblique impacts that are capable of ejecting melted material farther downrange. They may also be associated with older, nearby craters that no longer have a radar-bright proximal ejecta blanket. The observed morphology of the lunar crater flows has implications for similar features observed on Venus. In particular, changes in backscatter along many of the ejecta flows are probably caused by features typical of lava flows.

In order to assess the stratigraphy, sequence, and ages of impact basins and the impactor population as a function of time, we have used topography from the Lunar Orbiter Laser Altimeter (LOLA) on the Lunar Reconnaissance Orbiter (LRO) to measure the superposed impact crater size-frequency distributions for 30 lunar basins (D > or = 300 km). These data generally support the widely used Wilhelms sequence of lunar basins, although we find significantly higher densities of superposed craters on many lunar basins than derived by Wilhelms (50% higher densities). Our data also provide new insight into the timing of the transition between distinct crater populations characteristic of ancient and young lunar terrains. The transition from a lunar impact flux dominated by Population 1 to Population 2 occurred before the mid-Nectarian. This is before the end of the period of rapid cratering, and potentially before the end of the hypothesized Late Heavy Bombardment. LOLA-derived crater densities also suggest that many Pre-Nectarian basins, such as South Pole-Aitken, have been cratered to saturation equilibrium. Finally, both crater counts and stratigraphic observations based on LOLA data are applicable to specific basin stratigraphic problems of interest; for example, using these data, we suggest that Serenitatis is older than Nectaris, and Humboldtianum is younger than Crisium. Sample return missions to specific basins can anchor these measurements to a Pre-Imbrian absolute chronology.

The inflection point wavelength is sensitive to the degree of polymerization of silicates, which is strongly influenced by major cations - notably iron - in the minerals. Laboratory spectra of lunar soils demonstrate that the CF location is closely correlated to the sample's bulk FeO abundance, across the full range of Apollo soil samples, including pyroclastic glass. This correlation is the basis for estimating lunar surface FeO abundances using orbital thermal infrared measurements. The Diviner Lunar Radiometer Experiment on the Lunar Reconnaissance Orbiter includes three thermal infrared channels, selected to determine the CF positions for sites across the lunar surface. Diviner measurements are used to derive FeO abundances in the Aristarchus, Sulpicius Gallus, and Rima Fresnel pyroclastic deposits. The calculated FeO abundances for Aristarchus and Sulpicius Gallus lie within the compositional range of FeO-rich pyroclastic glasses but outside the range of most mare soils, supporting the interpretations of these deposits as glass rich. The calculated FeO abundance for the Rima Fresnel deposit is close to that of mare soils, supporting a contention that this deposit is dominated by basaltic fragments rather than glass. The Diviner measurements hold the potential to determine FeO abundances in many lunar pyroclastic deposits. A better understanding of these compositions will provide insight into the magmatic history and composition of the lunar interior, as well as an enhanced inventory of potential resources for future human exploration.

Most contain orthopyroxenes with mg#s of 70.6-79.0. Meteorite Hills (MET) 00425 is magnesian (mg# of 83.9). Lewis Cliff (LEW) 88011 contains orthopyroxene grains of varying mg# (76.3-68.6). Queen Alexandra Range (QUE) 93009 (orthopyroxene mg# 70.6) contains coarse-grained noritic clasts (plagioclase An (sub 84.7-88.3) ), and is rich in incompatible trace elements. It has Eu/Eu* < 1, indicating that cumulate norites do not dominate its trace element inventory. Queen Alexandra Range 93009 may be transitional between diogenites and magnesian cumulate eucrites. Lewis Cliff 88679, a dimict breccia of harzburgite and orthopyroxenite, has anomalously low concentrations of highly incompatible elements (e.g., Nb, La, Ta, U) compared to other diogenites, but is similar to them in less highly incompatible elements (e.g., Y, Zr, Yb, Hf). It is unlikely that this characteristic reflects a low proportion of a trapped melt component. The highly incompatible elements were likely mobilized after impact mixing of the two parent lithologies. Graves Nunataks 98108 shows an extreme range in Eu/Eu* attributable to the heterogeneous distribution of plagioclase; one sample has the lowest Eu/Eu* among diogenites. We find no compelling evidence to support the hypothesis that diogenite parent magmas were contaminated by partial melts of the eucritic crust. We posit that subsolidus equilibration between orthopyroxene and minor/trace phases (including phosphates) resulted in preferential redistribution of Eu (super 2+) relative to Eu (super 3+) and other rare earth elements, and results in anomalously low Eu/Eu* in samples leached in acids that dissolve phosphates.

Twelve local Neutron Suppression Regions (NSRs) and Neutron Excess Regions (NERs) are detected. It is shown using the data from the LOLA and Diviner instruments that six NSRs have the empirical property "less local irradiation and lower temperature - fewer local neutrons." These NSRs may be identified with spots of water-ice rich permafrost on the Moon. It is shown that detected NSRs are include in both permanently shadowed and illuminated areas, and they are not coincident with Permanently Shadowed Regions (PSRs) at the bottom of polar craters, as has been commonly expected before LEND presented neutron data with high spatial resolution.

These are compared with the local neutron background measured outside PSRs in sunlit regions. Individual and collective analyses of PSR properties have been performed. Only three large PSRs, Shoemaker and Cabeus in the south and Rozhdestvensky U in the north, have been found to manifest significant neutron suppression. All other PSRs have much smaller suppression, only a few percent, if at all. Some even display an excess of neutron emission in comparison to the sunlit vicinity around them. Testing PSRs collectively, we have not found any average suppression for them. Only the group of 18 large PSRs, with area >200 km (super 2) , show a marginal effect of small average suppression, approximately 2%, with low statistical confidence. A approximately 2% suppression corresponds to approximately 125 ppm of hydrogen taking into account the global neutron suppression near the lunar poles and assuming a homogeneous H distribution in depth in the regolith. This means that all PSRs, except those in Shoemaker, Cabeus and Rozhdestvensky U craters, do not contain any significant amount of hydrogen in comparison with sunlit areas around them at the same latitude.

It covers more than 1 year of mapping phase starting on 15 September 2009. In our analyses we have created global maps showing regional variations in the flux of thermal (energy range 0.5 MeV), and compared these fluxes to variances in soil elemental composition, and with previous results obtained by the Lunar Prospector Neutron Spectrometer (LPNS). We also processed data from LEND collimated detectors and derived a value for the collimated signal of epithermal neutrons based on the comparative analysis with the LEND omnidirectional detectors. Finally, we have compared our final (after the data reduction) global epithermal neutron map with LPNS data.

The three anhydrous IDPs show Delta (super 17) O values ranging from -5 ppm to +1 ppm, which overlap with those of ferromagnesian silicate particles from comet Wild 2 and anhydrous porous IDPs. For the first time, internal oxygen isotope heterogeneity was resolved in two IDPs at the level of a few per mil in Delta (super 17) O values. Anhydrous IDPs are loose aggregates of fine-grained silicates ( or = few mu m) igneous textures. If anhydrous IDPs represent fine-grained particles from comets, the similar Delta (super 17) O values between anhydrous IDPs and Wild 2 particles may imply that oxygen isotope ratios in cometary crystalline silicates are similar, independent of crystal sizes and their textures. The range of Delta (super 17) O values of the three anhydrous IDPs overlaps also with that of chondrules in carbonaceous chondrites, suggesting a genetic link between cometary dust particles (Wild 2 particles and most anhydrous IDPs) and carbonaceous chondrite chondrules.

Large l-enantiomeric excesses (lee approximately 43-59%) of the alpha -hydrogen aspartic and glutamic amino acids were measured in Tagish Lake, whereas alanine, another alpha -hydrogen protein amino acid, was found to be nearly racemic (d nearly equal l) using both techniques. Carbon isotope measurements of d- and l-aspartic acid and d- and l-alanine in Tagish Lake fall well outside of the terrestrial range and indicate that the measured aspartic acid enantioenrichment is indigenous to the meteorite. Alternate explanations for the l-excesses of aspartic acid such as interference from other compounds present in the sample, analytical biases, or terrestrial amino acid contamination were investigated and rejected. These results can be explained by differences in the solid-solution phase behavior of aspartic acid, which can form conglomerate enantiopure solids during crystallization, and alanine, which can only form racemic crystals. Amplification of a small initial l-enantiomer excess during aqueous alteration on the meteorite parent body could have led to the large l-enrichments observed for aspartic acid and other conglomerate amino acids in Tagish Lake. The detection of nonterrestrial l-proteinogenic amino acid excesses in the Tagish Lake meteorite provides support for the hypothesis that significant enantiomeric enrichments for some amino acids could form by abiotic processes prior to the emergence of life.

Three main units are observed on the floor of the depression (2.9 km across, < or =64 m deep) located at the summit of a low-shield volcano: irregularly shaped mounds up to 20 m tall, a lower unit 1 to 5 m in relief that surrounds the mounds, and blocky material. Analyses of Lunar Reconnaissance Orbiter Camera images and topography show that features in Ina are morphologically similar to terrestrial inflated lava flows. Comparison of these unusual lunar mounds and possible terrestrial analogs leads us to hypothesize that features in Ina were formed through lava flow inflation processes. While the source of the lava remains unclear, this new model suggests that as the mounds inflated, breakouts along their margins served as sources for surface flows that created the lower morphologic unit. Over time, mass wasting of both morphologic units has exposed fresh surfaces observed in the blocky unit. Ina is different than the terrestrial analogs presented in this study in that the lunar features formed within a depression, no vent sources are observed, and no cracks are observed on the mounds. However, lava flow inflation processes explain many of the morphologic relationships observed in Ina and are proposed to be analogous with inflated lava flows on Earth.

The ejecta blankets of fresh lunar impact craters are expressed as halos of optical and radar bright material that gradually fade with time. Although compositional differences make inferring crater ages from optical albedo problematic, radar is less sensitive to composition and thus may provide a more reliable means of estimating age. In this work, we use radar data from the Miniature Radio Frequency (Mini-RF) instrument on the Lunar Reconnaissance Orbiter (LRO) to characterize the radar backscatter of large numbers of ejecta blankets. By analyzing the size-frequency distribution of these craters, we show that the lifetime of the radar-bright discontinuous ejecta blanket varies with crater diameter in a predictable way for craters with diameters between 0.45 and 5 km. Absolute ages of individual craters can then be estimated by combining this empirically derived model with estimates of the relative degradation state of each individual crater. The lifetimes of radar-bright discontinuous ejecta blankets are significantly shorter in the highlands than the maria, although this is likely due to local topography, creating difficulties in applying the method to the highlands. The cosmic ray exposure age of South Ray Crater, a fresh crater visited by Apollo 16, provides confirmation of these results. This method therefore provides a new way to accurately date small, fresh craters using the Mini-RF data set.

Xenoliths with dimensions between a few mu m and about 1 mm (microxenoliths) are "meteorite-trapped" analogues of micrometeorites collected on the Earth. However, they have the unique features of sampling the zodiacal cloud (1) at more ancient times than those sampled by micrometeorites and (2) at larger distances from the Sun (corresponding to the asteroid Main Belt) than that sampled by micrometeorites (1 AU). Herein we describe a systematic search for new xenoliths and microxenoliths in H chondrites, aimed at determining their abundance in these ordinary chondrites, analyzing their mineralogy, and searching for possible correlations with host meteorite properties. Sixty-six sections from 40 meteorites have been analyzed. Twenty-four new xenoliths have been discovered. About 87% of them are microxenoliths (i.e., 1 mm in their largest dimension. All the newly discovered xenoliths and microxenoliths are composed of carbonaceous chondritic material. Hence, the zodiacal cloud was dominated by carbonaceous material even in past epochs. All the new xenoliths and microxenoliths have been found in regolith breccias. Hydrous-phase-rich xenoliths and microxenoliths in H4 and H5 chondrites attest that their embedding happened after the end of the thermal metamorphism. All these data suggest that xenoliths and microxenoliths were embedded when their host meteorites were part of the parent body regolith. This, combined with the H chondrite impact age distribution, attests that the embedding may have happened as early as 3.5 Gyr ago.

Five different types of carbonaceous materials were identified based on their morphology and texture, observed by transmission electron microscopy: globular, vesicular, dirty, spongy, and smooth. Flash heating experiments were performed to explore whether some of these morphologies are the result of atmospheric entry processes. Each of these morphologies was found to have isotopically anomalous H and N. Rare C isotopic anomalies were also observed. The isotopic and morphological properties of several of these phases, particularly the organic globules, are remarkably similar to those observed in other extraterrestrial materials including carbonaceous chondrites, comet 81P/Wild 2 particles collected by the Stardust spacecraft, and Antarctic micrometeorites, indicating that they were widespread in the early solar system. The ubiquitous nature and the isotopic anomalies of the nanoglobules and some other morphologies strongly suggest that these are very primitive phases. Given that some of the isotopic anomalies (D and (super 15) N excesses) are indicative of mass fractionation chemical reactions in a very cold environment, and some others ( (super 13) C and (super 15) N depletions) have other origins, these carbonaceous phases come from different reservoirs. Whatever their origins, these materials probably reflect the first stages of the evolution of solar system organic matter, having originated in the outermost regions of the protosolar disk and/or interstellar cold molecular clouds.

The work reported here examined whether temperature-dependent carbon isotopic fractionation of FTT reactions might provide such a signature. Analyses of bulk organic deposits resulting from FTT experiments show a slight trend toward lighter carbon isotopic ratios with increasing temperature. It is unlikely, however, that these carbon isotopic signatures could provide definitive provenance for organic compounds in solar system materials produced through FTT reactions, because of the small scale of the observed fractionations and the possibility that signatures from many different temperatures may be present in any specific grain.

AN - 1282826720; 2013-015027 AB - The Arctic freshwater (FW) has been the focus of many modeling studies, due to the potential impact of Arctic FW on the deep water formation in the North Atlantic. A comparison of the hindcasts from ten ocean-sea ice models shows that the simulation of the Arctic FW budget is quite different in the investigated models. While they agree on the general sink and source terms of the Arctic FW budget, the long-term means as well as the variability of the FW export vary among models. The best model-to-model agreement is found for the interannual and seasonal variability of the solid FW export and the solid FW storage, which also agree well with observations. For the interannual and seasonal variability of the liquid FW export, the agreement among models is better for the Canadian Arctic Archipelago (CAA) than for Fram Strait. The reason for this is that models are more consistent in simulating volume flux anomalies than salinity anomalies and volume-flux anomalies dominate the liquid FW export variability in the CAA but not in Fram Strait. The seasonal cycle of the liquid FW export generally shows a better agreement among models than the interannual variability, and compared to observations the models capture the seasonality of the liquid FW export rather well. In order to improve future simulations of the Arctic FW budget, the simulation of the salinity field needs to be improved, so that model results on the variability of the liquid FW export and storage become more robust.

A multiscale ensemble Kalman filter (EnKF) is used, supplemented with a rule-based update. The satellite data are either left unscaled or are scaled for anomaly assimilation. The results are validated against in situ observations at 14 high-elevation Snowpack Telemetry (SNOTEL) sites with typically deep snow and at 4 lower-elevation Cooperative Observer Program (COOP) sites. Assimilation of coarse-scale AMSR-E SWE and fine-scale MODIS SCF observations both result in realistic spatial SWE patterns. At COOP sites with shallow snowpacks, AMSR-E SWE and MODIS SCF data assimilation are beneficial separately, and joint SWE and SCF assimilation yields significantly improved root-mean-square error and correlation values for scaled and unscaled data assimilation. In areas of deep snow where the SNOTEL sites are located, however, AMSR-E retrievals are typically biased low and assimilation without prior scaling leads to degraded SWE estimates. Anomaly SWE assimilation could not improve the interannual SWE variations in the assimilation results because the AMSR-E retrievals lack realistic interannual variability in deep snowpacks. SCF assimilation has only a marginal impact at the SNOTEL locations because these sites experience extended periods of near-complete snow cover. Across all sites, SCF assimilation improves the timing of the onset of the snow season but without a net improvement of SWE amounts.

This variability is caused by solar, meteorological, and other physical forcing as well as biological and chemical processes that affect optical properties and their distributions, which in turn control the propagation of light across the air-sea interface and within the upper ocean. Recent developments in several technologies and modeling capabilities have enabled the investigation of a variety of fundamental and applied problems related to upper ocean physics, chemistry, and light propagation and utilization in the dynamic near-surface ocean. The purpose here is to provide background for and an introduction to a collection of papers devoted to new technologies and observational results as well as model simulations, which are facilitating new insights into optical variability and light propagation in the ocean as they are affected by changing atmospheric and oceanic conditions.

Assimilation is conducted using an ensemble Kalman smoother (EnKS). Model estimates with and without assimilation are compared against independent observational data sets of snow water equivalent (SWE) and runoff. For SWE, modest improvements in mean difference (MD) and root-mean-square difference (RMSD) are achieved as a result of the assimilation. No significant differences in temporal correlations of SWE resulted. Runoff statistics of MD remain relatively unchanged while RMSD statistics, in general, are improved in most of the sub-basins. Temporal correlations are degraded within the most upstream sub-basin, but are, in general, improved at the downstream locations, which are more representative of an integrated basin response. GRACE assimilation using an EnKS offers improvements in hydrologic state/flux estimation, though comparisons with observed runoff would be enhanced by the use of river routing and lake storage routines within the prognostic land surface model. Further, GRACE hydrology products would benefit from the inclusion of better constrained models of postglacial rebound, which significantly affects GRACE estimates of interannual hydrologic variability in the Mackenzie River basin.

CALIOP observations between 15 and 20 April 2010 of volcanic ash plumes following the eruption of the Icelandic Eyjafjallajokull volcano are reported here. While CALIOP has limited spatial coverage due to nadir-only sampling, ash plumes were observed by CALIOP over a wide region - from the North Atlantic Ocean to eastern Europe - during both day and night. Due to its nadir-only view, however, CALIOP did not sample the densest ash plumes which were observed by passive satellite sensors and ground-based lidar. Lidar depolarization and spectral backscatter signatures are used to discriminate ash layers from clouds. Most ash was observed in thin layers of laminar appearance with thicknesses ranging from 0.4 km to a little more than 1 km and at relatively low altitudes, between 1 and 7 km. Most layers reported here produced strong lidar depolarization, indicating a predominance of ash over sulfate aerosol in the plumes. Estimates of lidar extinction-to-backscatter ratio allow the retrieval of profiles of ash optical properties. Layers were observed with mean optical extinction ranging from 0.03 km (super -1) to nearly 1 km (super -1) . Combined with an estimate of mass extinction efficiency, mass concentration profiles can also be estimated. These observations of the three-dimensional dispersion of the plume are complementary to observations from passive satellite instruments and ground-based lidars, and can be useful for verification of dispersion models such as those used by the Volcanic Ash Advisory Centers.

In this study, regional atmospheric and oceanic simulations are used to document such processes during an atmospheric coastal jet event off central Chile. The event is well reproduced by the atmospheric model and is associated with the migration of an anomalous anticyclone in the southeastern Pacific region during October 2000. A robust feature of the simulation is a sharp coastal wind dropoff, which is insensitive to model resolution. As expected, the simulated oceanic response is a significant sea surface cooling. A surface heat budget analysis shows that vertical mixing is a major contributor to the cooling tendency both in the jet core area and in the nearshore zone where the magnitude of this term is comparable to the magnitude of vertical advection. Sensitivity experiments show that the oceanic response in the coastal area is sensitive to wind dropoff representation. This is because total upwelling, i.e., the sum of coastal upwelling and Ekman pumping, depends on the scale of wind dropoff. Because the latter is much larger than the upwelling scale, coastal wind dropoff has only a weak positive effect on vertical velocities driven by Ekman pumping but has a strong negative effect on coastal upwelling. Interestingly though, the weakening of coastal winds in the dropoff zone has a larger effect on vertical mixing than on vertical advection, with both effects contributing to a reduction of cooling.

In this paper, the total freeboard derived from four approximately 2000 km transects are examined and compared with those from the 2009 ICESat campaign. Total freeboard, the sum of the snow and ice freeboards, is the elevation of the air-snow interface above the local sea surface. Prior to freeboard retrieval, signal dependent range biases are corrected. With data from a near co-incident outbound and return track on 21 April, we show that our estimates of the freeboard are repeatable to within approximately 4 cm but dependent locally on the density and quality of sea surface references. Overall difference between the ATM and ICESat freeboards for the four transects is 0.7 (8.5) cm (quantity in bracket is standard deviation), with a correlation of 0.78 between the data sets of one hundred seventy-eight 50 km averages. This establishes a level of confidence in the use of ATM freeboards to provide regional samplings that are consistent with ICESat. In early April, mean freeboards are 41 cm and 55 cm over first year and multiyear sea ice (MYI), respectively. Regionally, the lowest mean ice freeboard (28 cm) is seen on 5 April where the flight track sampled the large expanse of seasonal ice in the western Arctic. The highest mean freeboard (71 cm) is seen in the multiyear ice just west of Ellesmere Island from 21 April. The relatively large unmodeled variability of the residual sea surface resolved by ATM elevations is discussed.

To complement these weak points, combined datasets merged with shipborne/land gravity data and satellite data are generally compiled using global spherical harmonic, rectangular harmonic, or spherical cap harmonic analysis etc. However, each method also has a different resolution and accuracy. In this study, gravity anomalies and geoid undulations of South Korea and its vicinity are calculated using the spherical cap harmonic method, and the results are compared with those of GGM02C and EGM2008. Absolute and relative geoid height differences between GPS/leveling data and the results of various other methods show that the method used in this study has the lowest RMS error (0.271 m vs 0.344-0.416 m) and standard deviation (0.236 m vs 0.309-0.362 m). This implies that the spherical cap harmonic method has better resolution and accuracy than the other methods. The short wavelength gravity anomalies derived from the spherical cap harmonic coefficients are used to estimate the sediment thickness of the Ulleung Basin, which is poorly known. The sediment thickness of the Ulleung Basin is about 5 km at the center of the basin, and about 12 km at the southern margin.

There is an overall negative yearly trend of -51.5 plus or minus 4.1 x 10 super(3)km super(2)yr super(-1) (-4.1 plus or minus 0.3% decade super(-1)) in sea ice extent for the hemisphere. The yearly sea ice extent trends for the individual Arctic regions are all negative except for the Bering Sea: -3.9 plus or minus 1.1 x 10 super(3)km super(2)yr super(-1) (-8.7 plus or minus 2.5% decade super(-1)) for the Seas of Okhotsk and Japan, +0.3 plus or minus 0.8 x 10 super(3)km super(2)yr super(-1) (+1.2 plus or minus 2.7% decade super(-1)) for the Bering Sea, -4.4 plus or minus 0.7 x 10 super(3)km super(2)yr super(-1) (-5.1 plus or minus 0.9% decade super(-1)) for Hudson Bay, -7.6 plus or minus 1.6 x 10 super(3)km super(2)yr super(-1) (-8.5 plus or minus 1.8% decade super(-1)) for Baffin Bay/Labrador Sea, -0.5 plus or minus 0.3 x 10 super(3)km super(2)yr super(-1) (-5.9 plus or minus 3.5% decade super(-1)) for the Gulf of St. Lawrence, -6.5 plus or minus 1.1 x 10 super(3)km super(2)yr super(-1) (-8.6 plus or minus 1.5% decade super(-1)) for the Greenland Sea, -13.5 plus or minus 2.3 x 10 super(3)km super(2)yr super(-1) (-9.2 plus or minus 1.6% decade super(-1)) for the Kara and Barents Seas, -14.6 plus or minus 2.3 x 10 super(3)km super(2)yr super(-1) (-2.1 plus or minus 0.3% decade super(-1)) for the Arctic Ocean, and -0.9 plus or minus 0.4 x 10 super(3)km super(2)yr super(-1) (-1.3 plus or minus 0.5% decade super(-1)) for the Canadian Archipelago. Similarly, the yearly trends for sea ice areas are all negative except for the Bering Sea. On a seasonal basis for both sea ice extents and areas, the largest negative trend is observed for summer with the next largest negative trend being for autumn. Both the sea ice extent and area trends vary widely by month depending on region and season. For the Northern Hemisphere as a whole, all 12 months show negative sea ice extent trends with a minimum magnitude in May and a maximum magnitude in September, whereas the corresponding sea ice area trends are smaller in magnitude and reach minimum and maximum values in March and September.

More specifically, satellite passive-microwave data for the period November 1978-December 2010 reveal an overall positive trend in ice extents of 17 100 plus or minus 2300km super(2)yr super(-1). Much of the increase, at 13 700 plus or minus 1500km super(2)yr super(-1), has occurred in the region of the Ross Sea, with lesser contributions from the Weddell Sea and Indian Ocean. One region, that of the Bellingshausen/Amundsen Seas, has (like the Arctic) instead experienced significant sea ice decreases, with an overall ice extent trend of -8200 plus or minus 1200 km super(2)yr super(-1). When examined through the annual cycle over the 32-yr period 1979-2010, the Southern Hemisphere sea ice cover as a whole experienced positive ice extent trends in every month, ranging in magnitude from a low of 9100 plus or minus 6300 km super(2) yr super(-1) in February to a high of 24 700 plus or minus 10 000 km super(2) yr super(-1) in May. The Ross Sea and Indian Ocean also had positive trends in each month, while the Bellingshausen/Amundsen Seas had negative trends in each month, and the Weddell Sea and western Pacific Ocean had a mixture of positive and negative trends. Comparing ice-area results to ice-extent results, in each case the ice-area trend has the same sign as the ice-extent trend, but the magnitudes of the two trends differ, and in some cases these differences allow inferences about the corresponding changes in sea ice concentrations. The strong pattern of decreasing ice coverage in the Bellingshausen/Amundsen Seas region and increasing ice coverage in the Ross Sea region is suggestive of changes in atmospheric circulation. This is a key topic for future research.

These Monte Carlo simulations follow the effects of space weathering processes on the distribution of the volatiles over time. The model output constrains the coherence of volatile deposits with depth, lateral separation, and time. The results suggest that ice sheets become broken and buried with time. As impacts begin to puncture an initially coherent surficial ice sheet, small areas with a deficit of ice compared to surrounding areas are formed first. As time progresses, holes become prevalent and the anomalous regions are local enhancements of ice concentration in a volume. The 3-D distribution is also heterogeneous because the ice is buried to varying depths in different locations. Analysis of the coherence of ice on 10 cm scales predicts that putative ice sheets in anomalous radar craters are 1000 Myr old. For future in situ analysis of cold trap volatiles, a horizontal range of 10 m is sufficient to acquire surface-based measurements of heterogeneously distributed ice. These results also support previous analyses that Mercury's cold traps are young.

Numerical weather prediction (NWP) systems as operated by various weather centers produce global estimates of soil temperature. In this study in situ data collected over the state of Oklahoma are used to assess surface (soil) temperature from three NWP systems: (1) the integrated forecast system from the European Center for Medium range Weather Forecasts (ECMWF), (2) the modern-era retrospective analysis for research and applications (MERRA) from the NASA Global Modeling and Assimilation Office, and (3) the global data assimilation system used by the National Center for Environmental Prediction (NCEP). The results are presented by hour of day with specific attention directed to the SMAP early morning overpass time at around 6 A.M. local time, and the period of 1 April to 1 October 2009. It was found that the NWP systems estimate the 0.05 m soil temperature at this time of day with an overall root mean square error of 1.9 to 2.0 K. It is shown that this error can be reduced to 1.6 to 1.8 K when differences between the modeling and measurement depth are accounted for by synchronizing each NWP set to match the mean phase of the in situ data and adjusting the amplitude in accordance with heat flow principles. These results indicate that with little calibration all products meet the SMAP error budget criteria over Oklahoma.

Its success, however, depends on unbiased model predictions and unbiased observations. Here a suite of continental-scale, synthetic soil moisture assimilation experiments is used to compare two approaches that address typical biases in soil moisture prior to data assimilation: (1) parameter estimation to calibrate the land model to the climatology of the soil moisture observations and (2) scaling of the observations to the model's soil moisture climatology. To enable this research, an optimization infrastructure was added to the NASA Land Information System (LIS) that includes gradient-based optimization methods and global, heuristic search algorithms. The land model calibration eliminates the bias but does not necessarily result in more realistic model parameters. Nevertheless, the experiments confirm that model calibration yields assimilation estimates of surface and root zone soil moisture that are as skillful as those obtained through scaling of the observations to the model's climatology. Analysis of innovation diagnostics underlines the importance of addressing bias in soil moisture assimilation and confirms that both approaches adequately address the issue.

AN - 1151916090; 2012-100226 AB - Satellite data estimate a high dust deposition flux ( approximately 18 g m (super -2) a (super -1) ) into the northern South China Sea (SCS). However, observational evidence concerning any biological response to dust fertilization is sparse. In this study, we combined long-term aerosol and chlorophyll-a (Chl-a) measurements from satellite sensors (MODIS and SeaWiFS) with a 16-year record of dust events from surface PM (sub 10) observations to investigate dust transport, flux, and the changes in Chl-a concentration over the northern SCS. Our result revealed that readily identifiable strong dust events over this region, although relatively rare (6 cases since 1994) and accounting for only a small proportion of the total dust deposition ( approximately 0.28 g m (super -2) a (super -1) ), do occur and could significantly enhance phytoplankton blooms. Following such events, the Chl-a concentration increased up to 4-fold, and generally doubled the springtime background value (0.15 mg m (super -3) ). We suggest these heavy dust events contain readily bioavailable iron and enhance the phytoplankton growth in the oligotrophic northern SCS.

Whilst substantial progress has been made towards the improvement of Health related quality of life (HRQoL) in western countries, scarce evidence-based data exists on HRQol of thalassemia children and adolescents living in developing countries. Methods: We studied 60 thalassemia children from Middle Eastern countries with a median age of 10 years (range 5 to 17 years). HRQoL was assessed with the Pediatric Quality of Life Inventory (PedsQL) 4.0. The Questionnaire was completed at baseline by all patients and their parents. The agreement between child-self and parent-proxy HRQoL reports and the relationship between HRQoL profiles and socio-demographic and clinical factors were investigated. Results: The scores of parents were generally lower than those of their children for Emotional Functioning (mean 75 vs 85; p = 0.002), Psychosocial Health Summary (mean 70.3 vs 79.1; p = 0.015) and the Total Summary Score (mean 74.3 vs 77.7 p = 0.047). HRQoL was not associated with ferritin levels, hepatomegaly or frequency of transfusions or iron chelation therapy. Multivariate analysis showed that a delayed start of iron chelation had a negative impact on total PedsQL scores of both children (p = 0.046) and their parents (p = 0.007). Conclusions: The PedsQL 4.0 is a useful tool for the measurement of HRQoL in pediatric thalassemia patients. This study shows that delayed start of iron chelation has a negative impact on children's HRQoL.

Using this model, an analysis is made to determine the effect of monetary control on the fluctuations in economic output. The results indicate that monetary control can reduce the amplitude of fluctuations at frequencies near the region of historic business cycles. However, with significant time lags in the control loop, monetary control tends to increase the amplitude of the fluctuations at the higher frequencies. The study outlines how the investigator or student can use the tools developed in the field of manual-control analysis to study the nature of economic fluctuations and to examine different strategies for stabilization.

This framework is used to develop a set of equations that, in historical perspective, combine traditional concepts about the dynamics of economic systems and about the effects of random economic disturbances. This set of equations provides relationships among well-known ideas in general macroeconomics and provides a means to interrelate and examine ideas about stabilization policies. In this study, linear-control analysis is applied as an aid in understanding the fluctuations of business cycles in the past, and to examine monetary policies that might improve stabilization. The analysis shows how different policies change the frequency and damping of the economic system dynamics, and how they modify the amplitude of the fluctuations that are caused by random disturbances. Examples are used to show how policy feedbacks and policy lags can be incorporated, and how different monetary strategies for stabilization can be analytically compared. Representative numerical results are used to illustrate the main points.

Wingrove: engineering approaches to macroeconomic modeling AN - 1095629120; 4347415 AB - A continuous-time control model was formulated and fitted to macroeconomic data by an expert control engineer who worked at NASA-AMES in the 1980s, Rodney C. Wingrove. Two articles were prepared and made available to the aerospace industry at that time, however the authors feel that wider distribution of his study posthumously is warranted at this time. This introduction to the two Wingrove articles that follow provides background information on the technologies Wingrove was working with, as well as subsequent developments in both macroeconomic and engineering modeling and analysis technology. Our purpose is to stimulate further research along the same lines which can potentially lead to structural and/or policy rule improvements that can prevent the extremely turbulent abberations that have been seen in recent years, and promote steady growth with low inflation and low unemployment in a sustainable way. Of particular concern is the exploding national debt problem.

The risk of GvHD furthermore increased when recipients heterozygous for HLA-C KIR ligand groups (C1/C2) were transplanted from donors completely lacking activating KIRs (HR 6.1, 95% CI 1.9-19.2, P=0.002). We also found that the risk of rejection was highest when the recipient was homozygous for the C2 HLA-KIR ligand group and the donor carried two or more activating KIRs (HR 6.8, 95% CI 1.9-24.4, P=0.005). By interpolating the number of donor activating KIRs with recipient HLA-C KIR ligands, we created an algorithm capable of stratifying patients according to the immunogenetic risk of complications following unrelated HSCT. In clinical practice, this predictive tool could serve as an important supplement to clinical judgement and decision-making.

The bone may not fully recover after flight, leaving the individual at greater risk of fractures. Thus, countermeasures to prevent the changes in or facilitate the recovery of bone are necessary to protect the crewmembers. The research described here addresses this requirement.

The synchronicity of these changes suggest a regional external forcing, such as changes in coastal ocean heat transport and/or increased surface melt and subglacial runoff. A distinct contrast in rates of ice front retreat has been observed between glaciers north and south of 69 degree N latitude on along the East Greenland coast. This latitude corresponds with the northward limit of subtropical waters carried by the Irminger Current, suggesting variability in ocean heat transport as the dominant forcing. Glacier surging, however, is yet another mechanism of change in this region. In order to provide further spatial and temporal constraint on glacier change across this important oceanographic transition zone, we construct time series of thinning, retreat and flow speed of 37 marine-terminating glaciers along the central east Greenland coast from 2000 to 2010. We assess this dataset for spatial and temporal patterns that may elucidate the mechanisms of glacier change. We confirm that glacial retreat, dynamical thinning, and acceleration have been more pronounced south of 69 degree N, with a high degree of variability along the Blosseville Coast and little inter-annual change in Scoresby Sound. Our results support the conclusion that variability in coastal ocean heat transport is the primary driver of regional glacier change, but that local factors, such as surging and/or individual glacier morphology, are overprinted on this regional signal.

Geochemical and mineral compositions of supraglacial debris were determined by X-ray diffraction and X-ray fluorescence spectroscopy. This composition data was used as ground truth in evaluating field spectra and satellite supraglacial debris composition and mapping methods. Satellite remote sensing methods for characterizing glacial surface debris include visible to thermal infrared hyper- and multispectral reflectance and emission signature identification, semi-quantitative mineral abundance indicies and spectral image composites. Satellite derived supraglacial debris mineral maps displayed the predominance of layered silicates, hydroxyl-bearing and calcite minerals on Khumbu Himalayan glaciers. Supraglacial mineral maps compared with satellite thermal data revealed correlations between glacier surface composition and glacier surface temperature. Glacier velocity displacement fields and shortwave, thermal infrared false color composites indicated the magnitude of mass flux at glacier confluences. The supraglacial debris mapping methods presented in this study can be used on a broader scale to improve, supplement and potentially reduce errors associated with glacier debris radiative property, composition, areal extent and mass flux quantifications.

With the development of automated atmospheric correction algorithms, it is now feasible to produce large quantities of surface reflectance products using Landsat images. Validation of these products requires in situ measurements, which either do not exist or are difficult to obtain for most Landsat images. The surface reflectance products derived using data acquired by the Moderate Resolution Imaging Spectroradiometer (MODIS), however, have been validated more comprehensively. Because the MODIS on the Terra platform and the Landsat 7 are only half an hour apart following the same orbit, and each of the 6 Landsat spectral bands overlaps with a MODIS band, good agreements between MODIS and Landsat surface reflectance values can be considered indicators of the reliability of the Landsat products, while disagreements may suggest potential quality problems that need to be further investigated. Here we develop a system called Landsat-MODIS Consistency Checking System (LMCCS). This system automatically matches Landsat data with MODIS observations acquired on the same date over the same locations and uses them to calculate a set of agreement metrics. To maximize its portability, Java and open-source libraries were used in developing this system, and object-oriented programming (OOP) principles were followed to make it more flexible for future expansion. As a highly automated system designed to run as a stand-alone package or as a component of other Landsat data processing systems, this system can be used to assess the quality of essentially every Landsat surface reflectance image where spatially and temporally matching MODIS data are available. The effectiveness of this system was demonstrated using it to assess preliminary surface reflectance products derived using the Global Land Survey (GLS) Landsat images for the 2000 epoch. As surface reflectance likely will be a standard product for future Landsat missions, the approach developed in this study can be adapted as an operational quality assessment system for those missions.

Efforts are under way at NASA Glenn Research Center through support of the Intelligent Vehicle Health Management Project (IVHM) to develop and implement such sensor technology for a wide variety of applications. These efforts are focused on developing high temperature, wireless, low cost, and durable products. In an effort to address technical issues concerning health monitoring, this article considers data collected from an experimental study using high frequency capacitive sensor technology to capture blade tip clearance and tip timing measurements in a rotating turbine engine-like-disk to detect the disk faults and assess its structural integrity. The experimental results composed at a range of rotational speeds from tests conducted at the NASA Glenn Research Center's Rotordynamics Laboratory are evaluated and integrated into multiple data-driven anomaly detection techniques to identify faults and anomalies in the disk. In summary, this study presents a select evaluation of online health monitoring of a rotating disk using high caliber capacitive sensors and demonstrates the capability of the in-house spin system.
