Microthermometry and Raman spectroscopy showed that the fluid in the inclusions is an aqueous brine and they were trapped near 25 degrees C [1]. Their continued presence in the halite grains requires that their incorporation into the H chondrite asteroid was post metamorphism [2]. Abundant solid inclusions are also present in the halites. The solid inclusions include abundant and widely variable organics [2]. Analyses by Raman microprobe, SEM/EDX, synchrotron X-ray diffraction and TEM reveal that these grains include macromolecular carbon similar in structure to CV3 chondrite matrix carbon, aliphatic carbon compounds, olivine (Fo (sub 99-59) ), high-and low-Ca pyroxene, feldspars, magnetite, sulfides, lepidocrocite, carbonates, diamond, apatite and possibly the zeolite phillipsite [3]. Here we report organic analyses of these carbonaceous residues in Monahans halite using C-, N-, and O-X-ray absorption near edge structure (XANES). Approximately 100 nm-thick sections were extracted with a focused ion beam (FIB) at JSC from solid inclusions from Monahans halite. The sections were analyzed using the scanning transmission X-ray microscope (STXM) on beamline 5.3.2.2 at the Advanced Light Source, Lawrence Berkeley National Laboratory for XANES spectroscopy. C-XANES spectra of the solid inclusions show micrometer-scale heterogeneity, indicating that the macromolecular carbon in the inclusions have complex chemical variations. C-XANES features include 284.7 eV assigned to aromatic C=C, 288.4-288.8 eV assigned to carboxyl, and 290.6 eV assigned to carbonate. The carbonyl features obtained by C-XANES might have been caused by the FIB used in sample preparation. No specific N-XANES features are observed. Various degrees of 1s-delta +exciton shown in the C-XANES spectra indicate that the solid inclusions contain macromolecular carbon which experienced various degree of thermal processing. The natures of the macromolecular carbon in the solid inclusions observed by C-XANES are consistent with the previous studies showing that the solid inclusions have not originated from Monahans parent body [1-3].

GEMS grains are submicron-sized rounded objects (typically 100-500 nm in diameter) with nanometer-sized (10-50 nm) Fe-Ni metal and sulfide grains embedded in an amorphous silicate matrix. Several formation processes for GEMS grains have been proposed so far, but these models are still being debated [2-5]. Bradley et al. proposed that GEMS grains are interstellar silicate dust that survived various metamorphism or alteration processes in the protoplanetary disk and that they are amorphization products of crystalline silicates in the interstellar medium by sputter-deposition of cosmic ray irradiation, similar to space weathering [2,4]. This consideration is based on the observation of nano-sized crystals ( approximately 10 nm) called relict grains in GEMS grains and their shapes are pseudomorphs to the host GEMS grains. On the other hand, Keller and Messenger proposed that most GEMS grains formed in the protoplanetary disk as condensates from high temperature gas [3,5]. This model is based on the fact that most GEMS grains have solar isotopic compositions and have extremely heterogeneous and non-solar elemental compositions. Keller & Messenger (2011) also reported that amorphous silicates in GEMS grains are surrounded by sulfide grains, which formed as sulfidization of metallic iron grains located on the GEMS surface. The previous studies were performed with 2D observation by using transmission electron microscopy (TEM) or scanning TEM (STEM). In order to understand the structure of GEMS grains described above more clearly, we observed 3D structure of GEMS grains by electron tomography using a TEM/STEM (JEM-2100F, JEOL) at Kyoto University. Electron tomography gives not only 3D structures but also gives higher spatial resolution ( approximately a few nm) than that in conventional 2D image, which is restricted by the sample thickness ( approximately >50 nm). Three cluster IDPs (L2036AA5 cluster4, L2009O8 cluster13 and W7262A2) were used for the observations. IDP W7262A2 was collected without silicon oil, which is ordinary used to collect IDPs, so this sample has no possibility of contaminations caused by silicon oil or solvent to rinse it [6]. The samples were embedded in epoxy resin and sliced into ultrathin sections (50-300 nm) using an ultramicrotome. The sections were observed by BF-TEM (bright field-TEM) and HAADF-STEM (high angle annular dark field-scanning TEM) modes. Images were obtained by rotating the sample tilt angle over a range of + or -65 degree in 1 degree steps. The obtained images were reconstructed to slice images. Mineral phases in the slice images were estimated by comparing with a 2D elemental map obtained by an EDS (energy dispersive X-ray spectroscopy) system equipped in the TEM/STEM. Careful examination of the slice images confirmed that iron grains are embedded in the amorphous silicate matrix of the GEMS grains, but sulfide grains were mainly present on the surface of the amorphous silicate. These results are consistent with the model that GEMS grains formed as condensates [3,5], although more data are needed to conclude the origin of GEMS grains. The present study is the first successful example adapting the electron tomography to the IDPs. This type of analysis will be important for planetary material sciences in the future.

The Earth system, like the human body, comprises diverse components that interact in complex ways. We need to understand the Earth's atmosphere, lithosphere, hydrosphere, cryosphere, and biosphere as a single connected system. Our planet is changing on all spatial and temporal scales. This presentation will highlight how satellite observations are revolutionizing our understanding of and its response to natural or human-induced changes, and to improve prediction of climate, weather, and natural hazards.

The cooling rate of ureilites estimated from silicates is approximately a few degrees per hour, and it was considered to reflect catastrophic disruption of the ureilite parent body. Ureilites were broken into meter-sized fragments and then formed daughter body(ies) by re-accumulation. Fe-Ni metal is one of the major components of all types of ureilites. Almahata Sitta, having fallen on the earth in October 2008, was classified as a polymict ureilite and ureilitic fragments from the Almahata Sitta contain abundant Fe-Ni metal. In previous studies, some grain boundary metals in Almahata Sitta ureilites show unique textures, not found in main group ureilites. These textures show characteristic assemblages with various combinations of a-iron (bcc), .-iron (fcc), cohenite ([Fe,Ni]3C) and schreibersite ([Fe,Ni]3P). Those metal textures resemble the product by steelmaking process in the earth, for example martensite (a-iron and .-iron). Generally, these textures require rapid cooling equivalent to quenching by water (>100 ./s). However, the cooling rate estimated from silicates (ca. several ./h) is much slower than that in producing the martensite. Thus, these metal textures may record the event separated from the event that recorded in the silicates, that is, disruption of parent body. Therefore, studying these complicated metal textures will contribute to a better understanding of the formation and origin of metal in ureilites with the information about their thermal histories. Those metal textures were only found in Almahata Sitta fragment #44, in previous studies, but we found similar assemblages composed of iron metal and its compounds in other fragments of Almahata Sitta and Antarctic ureilites. Forms and abundances are variable depending on samples, but it is suggested that those mineral assemblages in Fe-Ni metal are commonly found in ureilites. To estimate the cooling rate which can form these iron and iron compounds textures, we performed cooling experiments by the electric furnace to heat and quench metal whose compositions correspond to metals showing complex metal phase assemblages in Almahata Sitta ureilite. The results suggest that those metal textures can be achieved in the cooling rate faster than the lowest limit between 10 ./s and 0.83 ./s, whose chemical composition is Fe (sub 79.2) Ni (sub 3.4) P (sub 2.5) Si (sub 2.7) C (sub 12.2) . At lower cooling rate (0.83 or 0.04 ./s) and 10 ./s of other starting material (Fe (sub 86.4) Ni (sub 2.8) P (sub 0.7) Si (sub 4.1) C (sub 6.0) ), interstitial schreibersite among rounded iron was detected and neither cohenite nor gamma -iron has been formed. In the carbon-free composition (Fe (sub 91.2) Ni (sub 3.9) P (sub 0.5) Si (sub 4.4) ), similar textures were not generated at all cooling rates. This cooling rate, forming metal textures, is much faster than that estimated from silicates, and thus it is concluded that the event recorded by the silicates and the event formed the metal textures were truly separated. Before disruption of ureilite parent body, primary metals probably melted and mixed with surrounding materials (graphite, phosphide and other iron compounds) to various extents at high temperature. The iron phase was considered to be uniformly gamma -iron. Then, the ureilite parent body was destroyed and silicate minerals obtained cooling rate by quenching. Later, daughter body(ies) formed by accumulation of meter-size fragments. If daughter body(ies) was either shocked while still hot or heated by shock and then disrupted into smaller fragments (cm-size), the formation of iron textures may be achieved by super rapid cooling exceeding 1 degrees C/s. The metal grains without gamma -iron would experience relatively slow cooling due to larger fragment size. Consequently, it is considered that the complex coexistences of iron and iron compounds found in ureilites have recorded temperature change and fragmentation process due to the impacts on the parent body and daughter body(ies).

N1 - Last updated - 2013-12-23 ER - TY - JOUR T1 - Mass-independent fractionation of sulfur isotopes during broadband SO (sub 2) photolysis; comparison between (super 16) O- and (super 18) O-rich SO (sub 2) AN - 1507180089; 2014-018220 AB - This paper describes a comparison of ultraviolet photolysis experiments undertaken with SO (sub 2) (oxygen with isotopes at natural abundance levels) and S (super 18) O (sub 2) ( (super 18) O-substituted oxygen). Experiments were conducted in a closed photocell using a deuterium lamp (principally 190-235 nm) under pressure regimes (5-25 Torr) that produced optically thick conditions for (super 32) SO (sub 2) and variable optical depths for other isotopologues. The experiments, which were designed to examine the effects of intramolecular isotopic substitution of oxygen atoms on the S-MIF produced during UV photolysis of SO (sub 2) , reveal generally reduced sulfur fractionation for (super 18) O-rich SO (sub 2) as compared to (super 16) O-rich SO (sub 2) . Model shielding calculations were undertaken using spectra that were shifted due to changes in rotational and vibrational energy levels. The model calculations suggest that processes in addition to rotational and vibrational shifts in absorption spectra play a role in the experimentally produced isotope effects. Such additional processes may include differences in primary photoexcitation arising from smaller peak-to-valley amplitudes for fine structure of (super 18) O-rich SO (sub 2) absorption spectra or an isotopically selective process associated with transitions between excited states.

But available geological and geochemical evidence suggest that at least 200 Myr, and possibly more than 700 Myr, elapsed between the advent of oxygenic photosynthesis and the establishment of an oxygen atmosphere. The interregnum implies that at least one other necessary condition for O (sub 2) needed to be met. Here we argue that the second condition was the oxidation of the surface and crust to the point where O (sub 2) became more stable than competing reduced gases such as CH (sub 4) . The cause of Earth's surface oxidation would be the same cause as it is for other planets with oxidized surfaces: hydrogen escape to space. The duration of the interregnum would have been determined by the rate of hydrogen escape and by the size of the reduced reservoir that needed to be oxidized before O (sub 2) became favored. We suggest that continental growth has been influenced by hydrogen escape, and we speculate that, if there must be an external bias to biological evolution, hydrogen escape can be that bias.

The MSL/SAM value was based on Quadrupole Mass Spectrometer measurements of an enriched atmospheric sample, with CO (sub 2) and H (sub 2) O removed. Doubly ionized nitrogen data at m/z 14 and 14.5 had the highest signal/background ratio, with results confirmed by m/z 28 and 29 data. Gases in SNC meteorite glasses have been interpreted as mixtures containing a Martian atmospheric component, based partly on distinctive (super 14) N/ (super 15) N and (super 40) Ar/ (super 14) N ratios. Recent MSL/SAM measurements of the (super 40) Ar/ (super 14) N ratio (0.51 + or - 0.01) are incompatible with the Viking ratio (0.35 + or - 0.08). The meteorite mixing line is more consistent with the atmospheric composition measured by Viking than by MSL. Abstract Copyright (2013), The Authors.

The results are compared to sulfur concentrations in the groundmass glass in order to estimate the mass of sulfur brought to surface during the eruption. Satellite measurements yield order of magnitude lower sulfur ( approximately 0.2 Tg) in the eruption plume than estimated from the difference between MI and the groundmass glass. This sulfur "deficit" is readily explained by sulfur adhering to tephra grains but principally by sulfide globules caused by basalt-sulfide melt exsolution before degassing. A mass balance calculation reveals that approximately approximately 0.8 Tg of SO (sub 2) is present as globules, representing approximately 50% of the total sulfur budget. Most of the sulfide globules likely reside at depth due to their elevated density, for potential later remobilization by new magma or hydrothermal circulation. Abstract Copyright (2013), .

The Icebreaker drill is an integral part of the Icebreaker mission concept to search for life in ice-rich regions on Mars. Since the mission targets Mars Special Regions as defined by the Committee on Space Research (COSPAR), the drill has to meet the appropriate cleanliness standards as requested by NASA's Planetary Protection Office. In addition, the Icebreaker mission carries life-detection instruments; and in turn, the drill and sample delivery system have to meet stringent contamination requirements to prevent false positives. This paper reports on the development and testing of the Icebreaker drill, a 1 m class rotary-percussive drill and triple redundant sample delivery system. The drill acquires subsurface samples in short, approximately 10 cm bites, which makes the sampling system robust and prevents thawing and phase changes in the target materials. Autonomous drilling, sample acquisition, and sample transfer have been successfully demonstrated in Mars analog environments in the Arctic and the Antarctic Dry Valleys, as well as in a Mars environmental chamber. In all environments, the drill has been shown to perform at the "1-1-100-100" level; that is, it drilled to 1?m depth in approximately 1 hour with less than 100 N weight on bit and approximately 100 W of power. The drilled substrate varied and included pure ice, ice-rich regolith with and without rocks and with and without 2% perchlorate, and whole rocks. The drill is currently at a Technology Readiness Level (TRL) of 5. The next-generation Icebreaker drill weighs 10 kg, which is representative of the flightlike model at TRL 5/6.

N1 - Last updated - 2013-12-16 ER - TY - JOUR T1 - The primary fO (sub 2) of basalts examined by the Spirit Rover in Gusev Crater, Mars; evidence for multiple redox states in the Martian interior AN - 1507182625; 2014-018179 AB - The primary oxygen fugacity (fO (sub 2) ) of basaltic melts reflects the mantle source oxidation state, dictates the crystallizing assemblage, and determines how the magma will evolve. Basalts examined by the Spirit Mars Exploration Rover in Gusev Crater range from the K-poor Adirondack class (0.02 wt% K (sub 2) O) to K-rich Backstay class (up to 1.2 wt% K (sub 2) O) and exhibit substantially more variation than observed in martian basaltic meteorites. The ratios of ferric to total iron (Fe (super 3+) /Fe (sub T) ) measured by the Mossbauer spectrometer are high (equivalent to -0.76 to +2.98Delta QFM; quartz-fayalite-magnetite buffer as defined by Wones and Gilbert, 1969), reflecting secondary Fe (super 3+) phases. By combining the Fe (super 3+) /Fe (sub T) of the igneous minerals (olivine, pyroxene, and magnetite) determined by Mossbauer spectrometer, we estimate primary fO (sub 2) for the Gusev basalts to be -3.6 to 0.5Delta QFM. Estimating the fO (sub 2) as a function of the dependence of the CIPW normative fayalite/magnetite ratios on Fe (super 3+) /Fe (sub T) yields a slightly smaller range of -2.58 to +0.57Delta QFM. General similarity between the fO (sub 2) estimated for the Gusev basalts and ranges in fO (sub 2) for the shergottitic meteorites (-3.8 to 0.2Delta QFM; Herd, 2003; Goodrich et al., 2003) suggests that the overall range of fO (sub 2) for the martian igneous rocks and mantle is relatively restricted. Like the shergottites (Herd, 2003), estimated fO (sub 2) of three Gusev classes (Adirondack, Barnhill and Irvine) correlates with a proxy for LREE enrichment (K (sub 2) O/TiO (sub 2) ). This suggests mixing between melts or fluids derived from reservoirs with contrasting fO (sub 2) and REE characteristics. Oxygen fugacity estimates for the martian interior suggest that tectonic processes have not led to sufficient recycling of oxidized surface material into the martian interior to entirely affect the overall oxidation state of the mantle.

To evaluate the role of microorganisms in their formation, samples collected from a range of depths were examined by scanning electron microscopy (SEM) and synchrotron radiation-based micro-X-ray fluorescence (mu m-XRF) spectroscopy to characterize both their outer surfaces as well as internal structures. Observed trends in both surface colonization as well as microbialite framework with increasing lake depth include decreasing microbial abundance on outer surfaces as well as increasing ratios of carbonate:biomass in the microbialites. Microscopic investigations of the interiors show bacteria and algae entrapped within calcite, with this calcite exhibiting micropores and casts similar in size and shape to microorganisms. Based on these observations, it is hypothesized that microbialite development in Pavilion Lake initiates calcite precipitation in phototrophic microbial mats, i.e., combined phototrophy and heterotrophy, followed by heterotrophic oxidation of organic matter leading to eventual carbonate infilling of the microbial-mineral matrix. In addition, an observed shift from cyanobacteria to algae with increasing lake depth suggests variability in contemporary conditions controlling microbialite growth and diagenesis. High photosynthetic growth rates at shallower depths result in significant porosity and friability due to biomass accumulation outpacing carbonate precipitation. At intermediate depths, lower light levels and slower growth rates of phototrophs lead to a greater proportion of the microbialite matrix being in-filled by carbonate. Carbonates precipitate initially within the bacteria-EPS matrix, with abundant uncalcified algae maintaining microbialite porosity. In the deepest waters, the presence of only sparse algal colonization as well as fine-grained, laminated metal-rich sediments covering microbialites suggests that present-day insolation levels are too low to support the development of photosynthetic microbial mats. As a consequence, heterotrophic carbonate precipitation has progressively in-filled these microbialite interiors to create lithified calcite fabrics that exhibit minimal porosity but preserve the casts of microorganisms as biosignatures. While the origin of microbialites in Pavilion Lake remains unknown, current observations provide valuable information in evaluating how environmental conditions influence microbialite growth in a freshwater, lacustrine environment.

The Apollo lunar seismic data constitute a unique resource being the only seismic data set which can be used to infer the interior structure of a planetary body besides the Earth. On-going analysis and interpretation of the seismic data continues to provide constraints that help refine lunar origin and evolution. In addition to this, lateral variations in crustal thickness ( approximately 0-80 km) are being mapped out at increasing resolution from gravity and topography data that have and continue to be collected with a series of recent lunar orbiter missions. Many of these also carry onboard multi-spectral imaging equipment that is able to map out major-element concentration and surface mineralogy to high precision. These results coupled with improved laboratory-based petrological studies of lunar samples provide important constraints on models for lunar magma ocean evolution, which ultimately determines internal structure. Whereas existing constraints on initial depth of melting and differentiation from quantitative modeling suggested only partial Moon involvement (<500 km depth), more recent models tend to favor a completely molten Moon, although the former cannot be ruled out sensu stricto. Recent geophysical analysis coupled with thermodynamical computations of phase equilibria and physical properties of mantle minerals suggest that the Earth and Moon are compositionally distinct. Continued analysis of ground-based laser ranging data and recent discovery of possible core reflected phases in the Apollo lunar seismic data strengthens the case for a small dense lunar core with a radius of <400 km corresponding to 1-3% of lunar mass.

Spaceflight-related retinal changes, including oxidative stress and neuronal loss, have been previously reported in mice. Methods: Animal tissue from experiments aboard shuttle missions STS-133 (BALB/cJ mice, albino strain) and STS-135 (C57BL mice, pigmented strain), along with ground controls, was examined to determine survival of intrinsically photosensitive retinal ganglion cells (ipRGC) and melanopsin expression in retinas of mice exposed to the spaceflight environment. Real-time qPCR (RTqPCT) and microarray approaches were used to analyze Opn4 (melanopsin) gene expression, while immunohistologic studies were conducted to detect melanopsin localization in the retina. Results: Opn4 expression was decreased in albino BALB/cJ mice exposed to spaceflight, as measured by RTqPCR, but not in C57BL mice samples as analyzed by microarray. Opn4 expression returned to control levels at 7 d postreturn in the BALB/cJ samples. Melanopsin positive RGCs were found in the expected proportion in all samples, except for the BALB/cJ samples at 1 d after flight, where virtually no immunoreactive cells were found. Discussion: Spaceflight environmental factors may affect the nonvisual function of the retina, mediated by a reduction in melanopsin expression and ipRGC survival, contributing to circadian disruption.

The accompanying release of lead (Pb) stored in bones would increase the concentration of Pb in the blood (PbB), thereby complicating efforts to set acceptable Pb concentrations for spacecraft drinking water (PbW). Methods: A physiologically based pharmacokinetic (PBPK) model was modified to permit modeling the effects on PbB of temporarily increased rates of bone loss and various PbW concentrations. Results: The model predicts that, for the average American astronaut, the increase in PbB due to Pb released from bones would be more than offset by decreases in ingested or inhaled spacecraft environmental Pb, so that calculated PbB levels actually decrease in microgravity when PbW < about 9 [mu]g Pb [middot] L super(-1). Measured PbB in astronauts before and immediately after 6-mo stays on the International Space Station (ISS) support these results. Currently, PbW on the ISS averages 0.6 [mu]g Pb [middot] L super(-1) and PbW on Earth at the Johnson Space Center averages about 5 [mu]g Pb [middot] L super(-1). Conclusions: Most astronauts on long spaceflights will not be adversely affected by the release of lead from bones into the blood. A small percentage of astronauts (assuming there could be any who would have high concentrations of lead in their bones) could be at risk of experiencing elevated levels of PbB due to microgravity-accelerated release of Pb from their bones, depending on their individual rate of bone loss.

Individual simulations from the NINT version of GISS ModelE-R (part of the CMIP5 archive) of the last millennium, from year 850 to 2005, enabled with only 3 water isotopologue tracers, required nearly equal 9 months of computational time on the state-of-the-art parallel computing cluster of NCCS. The additional requirements of the full chemistry module would increase this by a factor of nearly equal 3. And yet, it is well known that chemistry and aerosols are very important on climate, both regional and global. Therefore, we have designed a set of experiments where the ocean and sea ice boundary conditions of the coupled model, paired with the land surface, greenhouse gases, insolation, and total solar irradiance (TSI) forcing from the PMIP3 protocol are applied to a series of full-chemistry GISS ModelE snap-shots each 50-years through the last millennium. We will present results from atmosphere-only model simulations with the GISS ModelE, which includes interactive gas-phase chemistry and aerosols at decadal-scale time slices, driven by millennial-length simulations performed with the same model when coupled with an ocean model. The boundary conditions for the transient simulations follow the last millennium coordinated PMIP3 experiment protocol. This experiment directly links in with other pre-industrial experiments being completed as part of IPCC AR5, using the same model and resolution as in GISS IPCC AR5. The impact of the presence of short-lived gases and aerosols on the simulated climate is studied. The role of previously omitted forcing mechanisms will be performed during the whole simulated period. The results presented are the initial runs from a larger set of experiments that will assess the climate impact of changes to dust, sea-salt, and ocean-derived sulfate, biomass burning ozone-precursors and aerosols, organic carbon, wetland methane emissions, and a final set with all components. These species are standard components in the GISS model's 20th century simulations, so that we may compare millennial variability characteristics with those better constrained from more recent climate periods. Dust and sea-salt are wind-driven aerosols from deserts and oceans, sulfate comes from oxidation of volcanic and oceanic precursors, while organic carbon comes from biomass burning, secondary plant sources and primary oceanic emissions. Comparison of model and proxy records will test model-simulated mechanisms while the model provides insight into factors contributing to proxy variability. The addition of potentially important forcing mechanisms will enable a more comprehensive evaluation of the climate sensitivity.

What is unclear, however, is how peatland type influences the rate of carbon accumulation, the fate of that accumulated carbon in the short and long term, and the role of methane in the overall carbon cycle. Studies of modern peatlands have shown that fens (dominated by Cyperaceae) may accumulate peat more quickly than bogs (dominated by Sphagnaceae), but in many downcore studies, bog peat may have higher apparent accumulation rates. These generalizations, however, do not apply in all locations, climates, or times throughout the Holocene. To address this conundrum, we present data from several peatland locations throughout the circum-Arctic to determine what types of environments and climate regimes are effective for the long-term storage of carbon, fens or bogs, and what climate conditions promote the development of each peatland type. Our sites include peatlands in the Arctic and boreal regions of North America and Asia. We use a multiproxy approach to directly compare the apparent carbon accumulation rate and methane-recycling rate with peatland type and specific hydroclimatic parameters. To reconstruct peatland type, we use macrofossil analysis. We use compound-specific hydrogen isotope ratios of leaf-wax biomarkers to assess hydrological parameters such as growing season evaporation and seasonality of precipitation. We use the carbon isotope ratios of these same compounds to reconstruct the rate of methane recycling. By reconstructing peat type, carbon cycle and hydroclimatic parameters in the same samples, we most effectively compare their mutual influence.

While multicentury time series of tree-ring widths at hundreds of sites across Asia provide estimates of past rainfall, the oxygen isotope ratios of annual rings at some of these sites can reveal broader regional atmosphere-ocean dynamics. Here we present a replicated, multicentury stable isotope series from Vietnam that integrates the influence of monsoon circulation on water isotopes. Stronger (weaker) monsoon flow over Indochina is associated with lower (higher) oxygen isotope values in our long-lived tropical conifers. Ring width and isotopes show particular coherence at multidecadal time scales, and together allow past precipitation amount and circulation strength to be disentangled. Combining multiple tree-ring proxies with simulations from isotope-enabled and paleoclimate general circulation models allows us to independently assess the mechanisms responsible for proxy formation and to evaluate how monsoon rainfall is influenced by ocean-atmosphere interactions at timescales from interannual to multidecadal.

The occurrence of fires is a complex function of climate, moisture, vegetation and landscape type. Fires impact environments in multiple ways, e.g., increase in soil erosion, change of vegetation type, and increase in nutrient levels in soils and lakes that receive runoff from burned areas. Sediment cores that contain an archive of deposition of combustion products can help reconstruct the history of past fires. In this study, alkylated PAHs and black carbon (char and soot) were used to explore the paleofire history reflected in a sediment core collected from Linsley Pond, Connecticut (41 degrees 18'N, 72 degrees 45'W). Biomass type and combustion levels of these fires and whether they occurred locally or regionally can be derived from these indicators. Such details, together with other paleoenvironmental indicators recorded in sediment cores (e.g., pollen, macrofossils, and LOI) helped unravel the environmental conditions before and after fires. Alkanes, PAHs, alkylated PAHs, and the ratio of soot to char indicate that in the Younger Dryas, fire occurred at a relatively low temperature (i.e. smoldering), followed by an abrupt increase of flaming combustion of softwood (white pine) at the Holocene boundary. Our paleofire data supports the previous interpretations of a shift towards a warm and dry climate in the southern New England region at this time.

Most of the available Holocene climatic reconstructions are however, not based on a direct comparison of terrestrial, marine and ice records making it difficult to obtain an accurate understanding of the interactions of the atmosphere-ocean-land systems and their relationship in global climate variability. Few studies based on direct sea land comparison have been reported for some key areas of the eastern North Atlantic but almost none in the western North Atlantic. Here we present a direct comparison between terrestrial (pollen) and marine (planktonic delta 18O) proxies from a well dated (ten AMS 14C dates on planktonic foraminifera and seaweed) slope core (KNR 178-2 JPC 32), retrieved close to Cape Hatteras (35 degrees 58.58'N, 74 degrees 42.77'W, 1006 m). This study provides information on eastern North America vegetation and on the northwestern Atlantic sea surface response to both Holocene long-term and rapid climate changes. Five intervals, marked mainly by changes in temperate trees are associated with long term climate shifts (12000-9150 ka; 9150-7250 ka; 7250-5350 ka; 5350-2800 ka; 2800-700 ka). Over these intervals, several abrupt cooling events are noted, as well as several indications of shifts in moisture. The comparison of our data with those available and unpublished records from several key sites of the North Atlantic region, gives insights into the nature, timing and causes of Holocene climate oscillations in the North Atlantic region and in particular off Cape Hatteras.

Infrared (IR) and visible wavelength observing campaigns were planned on NASA's Stratospheric Observatory For Infrared Astronomy (SOFIA) and on National Solar Observatory Dunn (DST) and McMath-Pierce Solar Telescopes, respectively. We highlight our early results. SOFIA (+FORCAST) mid- to far-IR images and spectroscopy ( approximately 5-35 mu m) of the dust in the coma of ISON are to be obtained by the ISON-SOFIA Team during a flight window 2013 Oct 21-23 UT (r (sub h) approximately 1.18 AU). Dust characteristics, identified through the 10 mu m silicate emission feature and its strength, as well as spectral features from cometary crystalline silicates (Forsterite) at 11.05-11.2 mu m, and near 16, 19, 23.5, 27.5, and 33 mu m are compared with other Oort cloud comets that span the range of small and/or highly porous grains (e.g., C/1995 O1 (Hale-Bopp) and C/2001 Q4 (NEAT)) to large and/or compact grains (e.g., C/2007 N4 (Lulin) and C/2006 P1 (McNaught)). Measurement of the crystalline peaks in contrast to the broad 10 and 20 mu m amorphous silicate features yields the cometary silicate crystalline mass fraction, which is a benchmark for radial transport in our protoplanetary disk. The central wavelength positions, relative intensities, and feature asymmetries for the crystalline peaks may constrain the shapes of the crystals. Only SOFIA can look for cometary organics in the 5-8 mu m region. Spatially resolved measurements of atoms and simple molecules from when comet ISON is near the Sun (r (sub h) < 0.4 AU, near Nov-20--Dec-03 UT) were proposed for by the ISON-DST Team. Comet ISON is the first comet since comet Ikeya-Seki (1965f) suitable for studying the alkalai metals Na and K and the atoms specifically attributed to dust grains including Mg, Si, Fe, as well as Ca. DST's Horizontal Grating Spectrometer (HGS) measures 4 settings: Na I, K, C2 to sample cometary organics (along with Mg I), and [O I] as a proxy for activity from water (along with Si I and Fe I). State-of-the-art instruments that will also be employed include IBIS, which is a Fabry-Perot spectral imaging system that concurrently measures lines of Na, K, Ca II, or Fe, and ROSA (CSUN/QUB), which is a rapid imager that simultaneously monitors Ca II or CN. From McMath-Pierce, the Solar-Stellar Spectrograph also will target ISON (320-900 nm, R approximately 21,000, r (sub h) <0.3 AU). Assuming survival, the intent is to target ISON over r (sub h) <0.4 AU, characteristic of prior Na detections.

Other instances of hot (Io) and cold (Mars, Triton) volcanism beyond Earth are known if not fully understood. We revisit, in comparison to other models, the "Old Faithful" theory of radiolytic gas-driven cryovolcanism first proposed by Cooper et al. [Plan. Sp. Sci. 2009]. In the energetic electron irradiation environment of Enceladus within Saturn's magnetosphere, a 10-percent duty cycle could be maintained for current geyser activity driven by gases from oxidation of ammonia to N2 and methane to CO2 in the thermal margins of a south polar sea. Much shorter duty cycles down to 0.01 percent would be required to account for thermal power output up to 16 GW, Steady accumulation of oxidant energy over four billion years could have powered all Enceladus emissions over the past four hundred thousand to four hundred million years. There could be separate energy sources driving mass flow and thermal emission over vastly different time scales. Since episodic tidal dissipation on 10 Myr time scales at 0.1-1 Gyr intervals [O'Neill and Nimmo, Nature 2010], and thus duty cycles 1-10 percent, could heat the polar sea to the current level, the radiolytic energy source could easily power and modulate the geyser mass flow on million-year time scales. Maximum thermal emission temperature 223 K [Abramov and Spencer, Icarus 2009] hints at thermal buffering in the basal and vent wall layers by a 1:1 H2O:H2O2 radiolytic eutectic, assuming deep ice crust saturation with H2O2 from long cumulative surface irradiation and downward ice convection. Due to density stratification the peroxide eutectic and salt water layers could separate, so that the denser peroxide layer (1.2 g/cc) descends to the polar sea while the lighter salt water (1.05 g/cc) rises along separate channels. Methane reservoirs could be found dissolved into the polar sea, or else trapped in hydrates [Kieffer et al., Science 2006] along flow paths and at the walls of the polar sea at surface depths below 20 km [Fortes, Icarus 2007]. Driver gas production for cryovolcanism could occur wherever these two layers come into contact under requisite temperature and pressure conditions, e.g. from 220 K and 10 bar at the 10-km basal layer of the overlying ice crust to 647 K and 220 bars at the liquid water limit, above the core-mantle boundary at 460 bars [Fortes, Icarus 2007]. We expect H2O2 oxidation to ignite at high temperatures but metallic minerals could catalyze reactions at lower temperatures nearer the basal layer. Pressure effects on oxidation rates are uncertain. Definitive modeling of Enceladus cryovolcanism likely involves synthesis of key processes from multiple models: Cold Faithful [Porco et al., Science 2006], Frigid Faithful [Keiffer et al., Science 2006], Frothy Faithful [Fortes, Icarus 2007], Old Faithful, and "Perrier Ocean" recirculation [Matson et al., Icarus 2012].

As first reported in Mahaffy et al. (Science, 341:263, 2013), and supported by repeated measurements over the course of the first Earth year of the mission, the (super 40) Ar/N ratio measured by SAM is approximately 0.5 - a significantly higher ratio than measured by Viking ( approximately 0.33) in the 1970s. Given the expected stability of both Ar and N (sub 2) in the Mars atmosphere, the apparent change in their ratio is a surprising result. We will show the Mars data from the SAM Quadrupole Mass Spectrometer (QMS), with a focus on the analysis and ground calibration that yield the current (super 40) Ar/N ratio. We will show the robustness of this ratio against the changing environmental conditions in Gale Crater, such as season, pressure, and CO (sub 2) mixing ratio. Measurements of the (super 15) N/ (super 14) N of N (sub 2) have been made, concurrently with the (super 40) Ar/N and in separate enrichment experiments, and these will also be presented to allow for comparisons to the meteorite mixing line (eg. Becker and Pepin, EPSL, 69:225, 1984). Finally, we will explore possible mechanisms by which a significant change in (super 40) Ar/N over approximately 30 years may be reconciled, with implications for the dynamism of the Mars atmosphere and exchange of gases with the regolith.

Forsterite features are identified in cometary comae near 10, 11.05-11.2, 16, 19, 23.5, 27.5 and 33 mu m, so accurate models for forsterite's absorption efficiency (Qabs) are a primary requirement to compute IR spectral energy distributions (SEDs, lambda Flambda vs. lambda ) and constrain the silicate mineralogy of comets. Forsterite is an anisotropic crystal, with three crystallographic axes with distinct indices of refraction for the a-, b-, and c-axis. The shape of a forsterite crystal significantly affects its spectral features . We need models that account for crystal shape. The IR absorption efficiencies of forsterite are computed using the discrete dipole approximation (DDA) code DDSCAT. Starting from a fiducial crystal shape of a cube, we systematically elongate/reduce one of the crystallographic axes. Also, we elongate/reduce one axis while the lengths of the other two axes are slightly asymmetric (0.8:1.2). The most significant grain shape characteristic that affects the crystalline spectral features is the relative lengths of the crystallographic axes. The second significant grain shape characteristic is breaking the symmetry of all three axes. Synthetic spectral energy distributions using seven crystal shape classes are fit to the observed SED of comet C/1995 O1 (Hale-Bopp). The Hale-Bopp crystalline residual better matches equant, b-platelets, c-platelets, and b-columns spectral shape classes, while a-platelets, a-columns and c-columns worsen the spectral fits. Forsterite condensation and partial evaporation experiments demonstrate that environmental temperature and grain shape are connected. Thus, grain shape is a potential probe for protoplanetary disk temperatures where the cometary crystalline forsterite formed. The forsterite crystal shapes (equant, b-platelets, c-platelets, b-colums - excluding a- and c-columns) derived from our modeling of comet Hale-Bopp, compared to laboratory synthesis experiments, suggests that these crystals are high temperature condensates. By observing and modeling the crystalline features in comet ISON, we may constrain forsterite crystal shape(s) and link to their formation temperature(s) and environment(s).

In 2011 we published an estimate of the current heat flow from Enceladus' active south polar terrain: 15.8+ or -3.1 GW (Howett et al., 2011). This value was calculated by first estimating by modeling, and then removing, the passive component from 17 to 1000 micron observations made of the entire south polar terrain by Cassini's Composite Infrared Spectrometer (CIRS). The heat flow was then directly calculated from the residual, assumed endogenic, component. The derived heat flow of 15.8 GW was surprisingly high, about 10 times greater than that predicted by steady-state tidal heating (Meyer and Wisdom, 2007). CIRS has also returned high spatial resolution observations of Enceladus' active south polar terrain. Two separate observations are used: 9 to 16 micron observations taken over nearly the complete south polar terrain and a single 17 to 1000 micron scan over Damascus, Baghdad and Cairo. The shorter wavelength observations are only sensitive to high temperature emission (>70 K), and so longer wavelength observations are required (despite their limited spatial coverage) to estimate the low temperature emission from the stripes. Analysis of these higher resolution observations tells a different story of Enceladus' endogenic heat flow: the preliminary estimate of the heat flow from the active tiger stripes using these observations is 4.2 GW. An additional 0.5 GW must be added to this number to account for the latent heat release by the plumes (Ingersoll and Pankine 2009), giving a total preliminary estimate of 4.9 GW. The discrepancy in these two numbers is significant and we are currently investigating the cause. One possible reason is that there is significantly higher endogenic emission from the regions between the tiger stripes than we currently estimate (based on the comparison of the single long-wavelength scan across the fractures). It is also possible that the earlier modeling efforts underestimated Enceladus' passive emission, resulting in an overestimation of Enceladus' heat flow.

The plume brightness varies by a factor of four as Enceladus orbits Saturn. The plume brightens dramatically as Enceladus approaches its orbital apocenter, and is dimmer near pericenter. The brightness is linked to the amount of material being erupted from the Tiger Stripe fractures in Enceladus' south polar region. The observation of variations in plume brightness (or eruptive output) supports a theoretical model of diurnal tidal stress controlling the location and timing of eruptions from these fractures. Diurnal tidal stress will cyclically place these fractures under tension and compression, which may cause the Tiger Stripes to open and close daily. If conduits to subsurface volatile reservoirs were established while fractures are in tension, the tidally-controlled fault motion would dictate the eruptive output. This tidal stress model predicts that the Tiger Stripes would experience more tensile stresses near apocenter, thus facilitating more eruptive activity at that time. Tidal stress calculations are based on the tidal flexing expected to occur on Enceladus; surface deformation in response to tidal stresses can only be inferred. The predicted fault motions are small and are not currently observable. However, an Earth analog from the Ross Ice Shelf, Antarctica, may provide insight for the process of induced diurnal tidal motions. Rifts on Antarctic ice shelves are tensile fractures in the floating ice shelf. While the rifts on the Ross Ice Shelf exhibit secular dilation, which causes them to widen with time, data of their motion also show a distinctly diurnal signal. The Ross Ice Shelf experiences tidal forces from both the Moon and Sun, and these forces induce small tidal motions on rifts in the ice shelf. GPS data show small, diurnal tidal motions that dilate and constrict the rift daily. From this analog we conclude that the diurnal tidal motion model for Enceladus may be credible.

Since the 1960s orbiters, landers, rovers, and earth-based telescopic observations show that its climate system is dynamic. Its dynamic nature, largely the result of atmosphere-surface interactions, is most obvious in the seasonal cycles of dust, water, and carbon dioxide that define the planet's climate system. These cycles are linked through the global circulation and MGS, Odyssey, Phoenix, MER, Mars Express, MRO, and now MSL have continuously observed them at Mars for the past 16 years. Their observations show that while the seasonal cycles are largely annually repeatable, there are interannual variations. Planet-encircling dust storms, for example, are quasi-triennial and originate over a broader range of seasons and locations than previously thought. Water moves from pole-to-pole each year in a largely, but not precisely, repeatable pattern that suggests but does not demand non-polar surface reservoirs. And the seasonal CO2 polar caps grow and retreat in a very predictable way with only minor deviations from year-to-year in spite of significant differences in atmospheric dust content. These behaviors suggest a complicated but robust coupled system in which these cycles interact to produce the greatest interannual variability in the dust cycle and least variability in the CO2 cycle. The nature of these interactions is the subject of ongoing research, but clouds, both water ice and CO2 ice, now appear to play a bigger role than believed at the end of the 20th century. There may also be some long-term trends in these cycles as there is evidence from imaging data, for example, that the south polar residual cap may not be stable on decadal to centennial time scales. On even longer time scales, the discovery of as much as 5 mb global equivalent of buried CO2 ice near the south pole, the detection of vast quantities of subsurface water ice at very shallow depths in midlatitudes of both hemispheres, and the presence of remnant glacial features at almost all latitudes, strongly suggests the possibility of significant climate change associated with orbital variations. Some of the major questions these data raise concern how closed the seasonal cycles are and which reservoirs are gaining or loosing, the cause of the large interannual variability of the dust cycle and how it couples to the water and CO2 cycles, and the mechanisms for the origin of past glacial activity and the emplacement and removal of subsurface ice. While many of these questions can be addressed with continued research based on existing data, new observations focused on atmosphere surface-interactions would provide valuable constraints on how dust, water, and CO2 move between the surface and atmosphere.

Carefully chosen analog sites provide a unique natural laboratory with high relevance to the associated science on these solar system target bodies. Volcanism and impact cratering are fundamental processes on the Moon, NEAs, and Phobos and Deimos. The terrestrial volcanic and impact records remain invaluable for our understanding of these processes throughout our solar system, since these are our primary source of firsthand knowledge on volcanic landform formation and modification as well as the three-dimensional structural and lithological character of impact craters. Regarding impact cratering, terrestrial fieldwork can help us to understand the origin and emplacement of impactites, the history of impact bombardment in the inner Solar System, the formation of complex impact craters, and the effects of shock on planetary materials. Volcanism is another dominant geologic process that has significantly shaped the surface of planetary bodies and many asteroids. Through terrestrial field investigations we can study the processes, geomorphic features and rock types related to fissure eruptions, volcanic constructs, lava tubes, flows and pyroclastic deposits. Also, terrestrial analog studies have the advantage of enabling simultaneous robotic and/or human exploration testing in a low cost, low risk, high fidelity environment to test technologies and concepts of operations for future missions to the target bodies. Of particular interest is the importance and role of robotic precursor missions prior to human operations for which there is little to no actual mission experience to draw upon. Also critical to understanding new worlds is sample return, and analog studies enable us to develop the appropriate procedures for collecting samples in a manner that will best achieve the science objectives.

LADEE will also determine whether dust is present in the lunar exosphere, and reveal its sources and variability. These investigations are relevant to our understanding of surface boundary exospheres and dust processes occurring at many objects throughout the solar system, address questions regarding the origin and evolution of lunar volatiles, and have potential implications for future exploration activities. Following a successful launch, LADEE will enter a series of phasing orbits, which allows the spacecraft to arrive at the Moon at the proper time and phase. This approach accommodates any dispersion in the Minotaur V launch injection. LADEE's arrival at the moon depends on the launch date, but with the Sept. 6 launch date it should arrive at the Moon in early October. The spacecraft will approach the moon from its leading edge, travel behind the Moon out of sight of the Earth, and then re-emerge and execute a three-minute Lunar Orbit Insertion maneuver. This will place LADEE in an elliptical retrograde equatorial orbit with an orbital period of approximately 24 hours. A series of maneuvers is then performed to reduce the orbit to become nearly circular with a 156-mile (250-kilometer) altitude. Spacecraft checkout and science instrument commissioning will commence in early-October and will nominally span 30 days but can be extended for an additional 30 days in the event of contingencies. Following commissioning, the 100-day Science Phase is performed at an orbit with periapsis between 20-60 km. This orbit must be constantly managed due to the Moon's highly inhomogeneous gravity field. During the Science Phase, the moon will rotate more than three times underneath the LADEE orbit. LADEE employs a high heritage instrument payload: a Neutral Mass Spectrometer (NMS) from Goddard Space Flight Center, an Ultraviolet/Visible Spectrometer (UVS) from Ames Research Center, and a dust detection experiment (LDEX) from the University of Colorado/LASP. It will also carry the Lunar Laser Communications Demonstration (LLCD) as a technology demonstration. The LLCD is funded by the Human Exploration Operations Mission Directorate (HEOMD), managed by GSFC, and built by the MIT Lincoln Lab. Contingent upon LADEE's successful lunar orbit insertion and checkout, we will report the early results from the science investigations.

This talk is intended to explain why. Despite its being the heaviest gas found in natural planetary atmospheres, there is more evidence that Xe escaped from Earth than for any element apart from helium: (i) Atmospheric Xe is very strongly mass fractionated (at about 4% per amu) from any known solar system source. This suggests fractionating escape that preferentially left the heavy Xe isotopes behind. (ii) Xe is underabundant compared to Kr, a lighter noble gas that is not strongly mass fractionated in air. (iii) Radiogenic Xe is strongly depleted by factors of several to approximately 100 compared to the quantities expected from radioactive decay of primordial solar system materials. In these respects Xe on Mars is similar to Xe on Earth, but with one key difference: Xe on Mars is readily explained by a simple process like hydrodynamic escape that acts on an initially solar or meteoritic Xe. This is not so for Earth. Earth's Xe cannot be derived by an uncontrived mass fractionating process acting on any known type of Solar System Xe. Earth is a stranger, made from different stuff than any known meteorite or Mars or even the Sun. Who else is in Earth's family? Comets? We know nothing. Father Zeus? Data from Jupiter are good enough to show that jovian Xe is not strongly mass-fractionated but not good enough to determine whether Jupiter resembles the Earth or the Sun. Sister Venus? Noble gas data from Venus are incomplete, with Kr uncertain and Xe unmeasured. Krypton was measured by several instruments on several spacecraft. The reported Kr abundances are discrepant and were once highly controversial. These discrepancies appear to have been not so much resolved as forgotten. Xenon was not detected on Venus. Upper limits were reported for the two most abundant xenon isotopes 129Xe and 132Xe. From the limited data it is not possible to tell whether Venus's affinities lie with the solar wind, or with the chondrites, with Earth, or with none of the above. Modern spacecraft mass spectrometers are at least 100-fold more sensitive to noble gases. Sending such an instrument to Venus may be the last best hope for decrypting what Earth's noble gases have been trying to tell us.

That water constitutes a resource that enables lunar exploration if it can be harvested for fuel and life support. Future lunar exploration missions will need detailed information about the distribution of volatiles in lunar permanently shadowed regions (PSRs). In addition, the volatiles also offer key insights into the recent and distant past, as they have trapped volatiles delivered to the moon over approximately 2 Gyr. This comprises an unparalleled reservoir of past inner solar system volatiles, and future scientific missions are needed to make the measurements that will reveal the composition of those volatiles. These scientific missions will necessarily have to acquire and analyze samples of volatiles from the PSRs. For both exploration and scientific purposes, the precise location of volatiles will need to be known. However, data indicate that ice is distributed heterogeneously on the Moon. It is unlikely that the distribution will be known a priori with enough spatial resolution to guarantee access to volatiles using a single point sample. Some mechanism for laterally or vertically distributed access will increase the likelihood of acquiring a rich sample of volatiles. Trade studies will need to be conducted to anticipate the necessary range and duration of missions to lunar PSRs that will be needed to accomplish the mission objectives. We examine the spatial distribution of volatiles in lunar PSRs reported from data analyses and couple those with models of smaller scale processes. FUV and laser data from PSRs that indicate the average surface distribution is consistent with low abundances on the extreme surface in most PSRs. Neutron and radar data that probe the distribution at depth show heterogeneity at broad spatial resolution. We consider those data in conjunction with the model to understand the full, 3-D nature of the heterogeneity. A Monte Carlo technique simulates the stochastic process of impact gardening on a putative ice deposit. The model uses the crater production function as a basis for generating a random selection of impact craters over time. Impacts are implemented by modifying the topography, volatile content, and depth distribution in the simulation volume on a case by case basis. This technique will never be able to reproduce the exact impact history of a particular area. But by conducting multiple runs with the same initial conditions and a different seed to the random number generator, we are able to calculate the probability of situations occurring. Further, by repeating the simulations with varied initial conditions, we calculate the dependence of the expectation values on the inputs. We present findings regarding the heterogeneity of volatiles in PSRs as a function of age, initial ice thickness, and contributions from steady sources.

In particular, Jupiter's icy satellite Europa has compelling evidence for the existence of a global subsurface ocean beneath a surface layer of water ice. This ocean decouples the ice shell from the solid silicate mantle, and amplifies tidally driven large-scale surface deformation. The complex fissures and cracks seen by orbital flybys suggest brittle failure is an ongoing and active process in the ice crust, therefore indicating a high level of associated seismic activity. Seismic probing of the ice, oceanic, and rocky layers would provide altogether new information on the structure, evolution, and even habitability of Europa. Any future missions (penetrators, landers, and rovers) planning to take advantage of seismometers to image the Europan interior would need to be built around predictions for the expected background noise levels, seismicity, wavefields, and elastic properties of the interior. A preliminary suite of seismic velocity profiles for Europa has been calculated using moment of inertia constraints, planetary mass and density, estimates of moon composition, thermal structure, and experimentally determined relationships of elastic properties for relevant materials at pressure, temperature and depth. While the uncertainties in these models are high, they allow us to calculate a first-order seismic response using 1-D and 3-D high frequency wave propagation codes for global and regional scale structures. Here, we show how future seismic instruments could provide detailed elastic information and reduced uncertainties on the internal structure of Europa. For example, receiver functions and surface wave orbits calculated for a single seismic instrument would provide information on crustal thickness and the depth of an ocean layer. Likewise, evaluation of arrival times of reflected wave multiples observed at a single seismic station would record properties of the mantle and core of Europa. Cluster analysis of waveforms from various seismic source mechanisms could be used to classify different types of seismicity originating from the ice and rocky parts of the moon. We examine examples of single station results for analogous seismic experiments on Earth, e.g., where broadband, 3-component seismometers have been placed upon the Ross Ice Shelf of Antarctica. Ultimately this work reveals that seismometer deployments will be essential for understanding the internal dynamics, habitability, and surface evolution of Europa, and that seismic instruments need to be a key component of future missions to surface of Europa and outer satellites.

AN - 1703693227; 2015-075031 AB - Our recent ground based observations suggest the trailing hemisphere of Europa may have magnesium sulfate salts produced from the irradiation of endogenous chlorine salts from the subsurface ocean. Upon irradiation the endogenous magnesium combines with exogenous, Iogenic sulfur to yield the observed magnesium sulfate. The spectroscopic signature of the magnesium sulfate is seen on the trailing but not the leading hemisphere, leading to the radiolytic interpretation of the production of this compound. Coupled with this pathway, the radiolytic chemistry occurring on Europa's surface yields significant hydrogen peroxide on the leading hemisphere, but not the trailing, and modest amounts of peroxide on the sub- and anti-jovian hemispheres. Here we detail the process, pathway, and geography of our proposed radiolytic salt cycle and couple our telescope observations with recent laboratory work.

Tessera terrain is temporally, morphologically, and perhaps also compositionally unique on Venus. Stratigraphic studies of tessera terrain establish that they consistently appear locally, and perhaps even globally, as the oldest material on a planet with an average surface crater retention age of approximately 500 million years. Thus, the tesserae provide the best chance to access rocks that are derived from the first 80% of the history of the planet, an era obscured by the emplacement of voluminous (presumably basaltic) plains. Analysis of Magellan imagery, topography and gravity data show that tessera terrain is characterized by higher strain rates and a thinner lithosphere than at present and thus records an extinct geodynamical era on Venus. Yet very little is understood about the number, morphology and stratigraphy of geologic units within tessera terrain, nor mass wasting processes operating on the surface. Improved radar imagery at the 5-25 m scale, and optical images below the clouds (<1 km) and at the surface will help assess the geologic processes operating in the pre-plains era. Such data products are also essential for judicious landing site selection, since tessera meter-scale roughness will limit landing site safety and sample access. Improved topography data are required to quantify the deformation recorded by ubiquitous tesserae structures that are finer than Magellan resolution. Tessera terrain is unsampled, but recent analyses of radiance from the surface at 1 micron using instruments on Venus Express and Galileo are consistent with felsic compositions for tesserae. Silicic compositions likely require both water and a plate recycling mechanism (e.g., subduction) for formation. The high D/H ratio of the Venus atmosphere is consistent with the loss of a significant inventory of water over the history of the planet. Felsic tesserae may herald from an ancient water-rich Venus, perhaps with an ocean and potentially habitable. Further assessment of tessera composition requires more comprehensive 1 micron radiance measurements from orbital, near-surface and surface platforms and in-situ measurement of mineralogy and chemistry. Radiance data need to be supported by improved laboratory measurements of the emissivity of relevant rocks and weathering products in a Venus environment. Venus weathering experiments also support the interpretation of in situ analyses at the surface of Venus and may constrain sampling strategy. If confirmed, felsic tesserae would be critical targets for sample return due to their potential to include ancient rocks and/or minerals formed in the presence of water (e.g., zircons). In sum, the tesserae are the oldest materials exposed on the Venus surface and are the best candidates for containing ancient rocks and for comprising evolved compositions. They uniquely and critically constrain the geochemistry, geodynamics and history of water on Venus through time.

Detailed evidence for their origin by impact includes: planar deformation features (PDFs in quartz, feldspars, pyroxene, olivine, etc.), asymmetric isotropization (i.e., alternate-twin deformation) in plagioclase, diaplectic phases, ultra-high temperature melting (e.g., lechatelierite, molten rutile) and decomposition (e.g., baddeleyite), and quench textures around minerals, e.g., beta-crystobalite, etc. Incorporation of materials from depth indicates that this was not an airburst but a series of crater-forming impacts. Many hand samples also contain relicts of extant biota. Scanning electron microprobe (SEM) images reveal preservation of delicate forms including: striated layers between vesicular impact glass and parallel vein-like features at higher magnification. The striated patterns resemble vascular bundles of the mesophyll (ground tissue) of a plant. Identifiable parts of the plant anatomy, e.g. papillae and cell walls, contain skeletal magnetite crystals and high-temperature, i.e., phases indicating that vitreous fossilization occurred at extremely high temperatures and rapid quench rates. The morphology is generally similar to contemporary regional grasses (pampas grass) including small spherules (papilla). The intricate forms (20nm to 20mm) indicate features rapidly preserved rather than simple impressions. Reaction zones (vesiculation and quenched minerals) along the interface between the melt and entrained plants indicate rapid quenching. Compositional mapping reveals the presence of insignificant levels of carbon, but chemical analyses confirm the high silica content (> 60%). Various analytical techniques (micro-Raman, TEM/SEM, and mu ltra-L2MS) further reveal the preserved organic materials, including tetracyclic pyrrolines, essential members of the group of porphyrin species that are produced through the thermal degradation of chlorophyll with heterogeneous survival of abundant C and N. The survival and preservations of organics within hydrous pockets in rapidly quenched impact glasses may provide a new strategy for identifying biomarkers of possible early life on ancient Mars. Impact melt could encapsulate and preserve this record. It is likely that the porous nature of the target (loess), which characterizes much of the Martian surface, would ensure flash-heat preservation under highly reducing conditions.

One portion of the wet chemistry experiment is composed of MTBSTFA (N-methyl-N-tert-butyldimethylsilyltrifluoroacetamide) / DMF (dimethylformamide). Indeed, chemical derivatization of polar molecular compounds is achieved by the MTBSTFA silylation reaction in order to transform refractory polar compounds into a more volatile form that can be analyzed and detected by GC-MS. Results obtained on Rocknest (Leshin et al. 2013; Glavin et al. 2013) and John Klein showed the presence of MTBSTFA reaction products in the system. This means that MTBSTFA is part of the background signal under its gaseous phase and is derived from at least one of the seven MTBSTFA/DMF filled derivatization cups in SAM. Since MTBSTFA is able to react in the gaseous phase, its detection implies the possibility to have some MTBSTFA reactions with all the labile compounds possibly present in the Martian soil, in the sampling system and/or inside the SAM instrument. As such, in order to better understand the portion of products detected coming from internal reactions, we have performed several lab experiments to mimic the SAM pyrolysis and gas processing system. Specifically, we have investigated possible MTBSTFA reactions with organics at high temperatures (100 degrees C up to 600 degrees C) from the SAM trap (Tenax(Registered)) and with oxychlorine compounds present on Mars (Glavin et al. 2013).

We are currently undertaking a project to create composite UV-IR spectra (0.1-5 microns) of the moons (Mimas, Enceladus, Tethys, Dione and Rhea) using data from the Ultraviolet Imaging Spectrograph (UVIS), the Imaging Subsystem (ISS) and the Visual-Near Infrared Mapping Spectrometer (VIMS). We present preliminary results. We anticipate that these composite spectra can be used to study the surface compositions of the satellites, their photometric behaviors (important for understanding surface structure) and effects of environmental interactions. Furthermore, the broad wavelength coverage allows us to probe different depths into the icy regoliths. Different spectral regions provide unique information not only on distinct/unique absorption features but on the depth sensed. We are particularly interested in probing the nature of the UV absorber(s) on these satellites; by studying the UV-IR composite spectra of the satellites, we can begin to understand how the UV absorber and other spectral features vary from body to body and place to place on each moon--providing clues to history and evolution of these intriguing bodies.

Despite global surface mapping by Magellan, discoveries by Venera landers, and ongoing atmospheric observations by the Venus Express (VEx) orbiter, significant questions about Venus remain unanswered. To place Venus into its proper context with respect to Mars and Earth, it is necessary to obtain new measurements that address top issues identified in the National Research Council (NRC) Solar System Decadal Survey: (1) evolution of the atmosphere, history of climate, and evidence of past hydrologic cycles; (2) history of volatiles and sedimentary cycles; and (3) planetary surface evolution. To answer these questions, new measurements are needed. First and foremost, in situ noble gas measurements are needed to constrain solar system formation and Venus evolution. In particular, the isotopic ratios of Xe and Kr can provide unique insights into planetary accretion. Isotopic measurements of nitrogen (15N/14N) will place important constraints on atmospheric loss processes. Current knowledge of this ratio has a substantial uncertainty of + or -20%. VEx observations of hydrogen isotopes indicate the D/H ratio above the clouds is substantially greater than measured by Pioneer Venus, and varies with height. High precision measurements of the vertical distribution of the D/H isotopic ratio below the cloud layers will provide constraints on models of the climate history of water on Venus. The majority of atmospheric mass is located below the clouds. Current data suggest intense interaction among atmospheric gases down to the surface. The haze within the cloud region of unknown composition plays a central role in the radiative balance. Photochemically-derived species (H2SO4, OCS, CO, Sn) are subjected to thermochemical reactions below the clouds, especially within 30 km of the surface. Competing temperature-pressure dependent reactions and atmospheric circulation may cause vertical and latitudinal gradients of chemically-active trace gases (e.g., SO2, H2S, OCS, CO). Measurements of the chemical composition of the near-surface atmosphere can be used to evaluate the stability of primary and secondary minerals and can help to understand chemistry of atmosphere-surface interactions. However, concentrations of many trace species have never been measured below approximately 30 km, and multiple in situ measurements are required to evaluate chemical processes and cycles of volatiles, which can only be accomplished with deep entry probes. Current lack of understanding about Venus not only limits our understanding of evolutionary pathways Earth could experience, but also suggests that we are ill-equipped to understand the evolution of star systems with similar-sized planets.

Two meteorites: Tissint, an olivine-phyric basaltic shergottite which fell over Morocco July 18th 2001; and the Antarctic meteorite Yamato 980459 (Y98), an olivine-phyric basaltic shergottite with abundant glassy mesostasis have been studied. Chondrite-normalized REE patterns for MI in Tissint and Y98 are characteristically LREE depleted and, within analytical uncertainty, parallel those of their respective whole rock composition; supporting each meteorite to represent a melt composition that has experienced closed-system crystallization. REE profiles for mesostasis glass in Y98 lie about an order of magnitude higher than those from the MI; with REE profiles for Tissint MI falling in between. Y98 MI have the highest average Sm/Nd and Y/Ce ratios, reflecting their LREE depletion and further supporting Y98 as one of our best samples to probe the depleted shergotitte mantle. In general, Zr/Nb ratios overlap between Y98 and Tissint MI, Ce/Nb ratios overlap between Y98 MI and mesostasis glass, and Sm/Nd ratios overlap between Y98 mesostasis glass and Tissint MI. These features support similar sources for both, but with subtle geochemical differences that may reflect different melting conditions or fractionation paths during ascent from the mantle. Interestingly, the REE patterns for all analyses in Y98 and possibly for those from Tissint as well display a flattening of the LREE that suggests an early crustal contribution to the shergottite mantle.

The main objective of our study is to characterize the radar response to the potential presence of aquifers, global ocean and ice tectonic structural elements associated to the moons thermal evolution. We performed a parametric detectability study of the above-mentioned features using the Finite Difference Time Domain (FDTD) method. The forward propagation were performed for a central frequency of 9 MHz, as suggested for future sounding experiments. Simulations were performed for several geoelectrical models that in turn represent different geological hypothesis of Europa, Ganymede and Callisto. We investigated the radar detectability and identification of three main subsurface features: brine aquifers, brittle-ductile interfaces and shallow faults. For each of them we studied the effect of their structural and dielectric properties on their identification considering different geological and geophysical scenarios. In particular we studied the effect of surface clutter and volume scattering on the detectability of the above-mentioned features. The amplitude and losses of the backscattered electromagnetic field of the incident radar pulse were evaluated as a function of the radar range time. Our simulations suggest that aquifer detectability is compromised by its depth, ice impurities content and by the surface and volume scattering. Aquifers are detectable between 7 and 25 dB above the 65 dB galactic noise level at depths ranging respectively from 4 to 2 km. Beyond 4 km of depth and considering the validity of the topographic and dielectric parameters used in our modeling, aquifers could be more challenging for a non ambiguous detection. For the brittle-ductile interface our simulation results suggests that it is identifiable between 2 and 3 km even under highly fractured subsurface conditions. Additionally the depth variation of the brittle ductile interface can be assessed from radar sounding. On contrary, detectability of faults on Ganymede is highly dependent on the dielectric properties of their inner fill materials that is yet to be characterized by our ongoing laboratory characterization of icy moon analog materials.

Recent analyses of data from the Spectroscopy for the Investigation of the Characteristics of the Atmosphere of Mars (SPICAM), the Thermal Emission Spectrometer (TES), and the Mars Climate Sounder (MCS) instruments offer some long overdue progress in constraining this aspect of aerosols. However, significantly more work remains to be done in order to better constrain and inform modern dynamical simulations of the Martian atmosphere. Thus, the primary goal of this work is to perform retrievals of particle size as a function of altitude for both dust and water ice aerosols using MCS. The MCS dataset with pole-to-pole coverage over a period of approximately 3.5 martian years, provides the crucial systematic temporal and spatial sampling. We will present a summary of our limb radiative transfer algorithms and retrieval schemes and the initial results of the application of our particle size retrieval scheme for dust and water ice.

These compounds were identified after samples were pyrolysed at temperatures up to approximately 835 degrees C through a combination of Evolved Gas Analysis (EGA) and Gas Chromatography Mass Spectrometry (GCMS). Since these chlorinated species were well above the background levels determined by empty cup blanks analyzed prior to solid sample analyses, thermal degradation of oxychlorine phases, such as perchlorate, present in the Martian soil, are the most likely source of chlorine needed to generate these chlorohydrocarbons. Laboratory analogue experiments show that terrestrial organics internal to SAM, such as N-methyl-N(tert-butyldimethylsilyl)trifluoroacetamide (MTBSTFA), a derivatization agent, can react with perchlorates to produce all of the chlorohydrocarbons detected by SAM. However, in pyrolysis-trap-GCMS laboratory experiments with MTBSTFA, C4 compounds are the predominant chlorohydrocarbon observed, whereas on SAM the C1 chlorohydrocarbons dominate (Glavin et al., 2013). This, in addition to the previous identification of chloromethane and dichloromethane by the 1976 Viking missions (Biemann et al., 1977), suggest that there could be another, possibly Martian, source of organic carbon contributing to the formation of the C1 chlorohydrocarbons, or other components of the solid samples analyzed by SAM are having a catalytic effect on chlorohydrocarbon generation. Laboratory analogue experiments investigated a suite of organic compounds that have the potential to accumulate on Mars (Benner et al., 2000) and thus serve as sources of carbon for the formation of chlorohydrocarbons detected by the SAM and Viking GCMS instruments. Experiments were conducted under SAM-like conditions using a commercial pyroprobe equipped with a SAM-like hydrocarbon trap and coupled to a GCMS. In general, when pyrolyzed with 1 wt.% calcium perchlorate, the C1 organic compounds (e.g. methanol, formic acid, and formaldehyde) produced only C1 chlorinated compounds while propanol and butyric acid formed only C3 chlorinated compounds. All of the pyrolysis experiments produced chlorobenzene, suggesting that it forms from chlorine, released during calcium perchlorate decomposition, reacting with benzene and toluene, released from the Tenax component of the hydrocarbon trap. Pyrolysis of phthalic acid however, produces a higher abundance of chlorobenzene than could be attributed to the Tenax alone and also forms C1 chlorohydrocarbons. Additional analogue experiments to identify potential precursor compounds for the chlorohydrocarbons detected by SAM are ongoing.

These conditions are believed to characterize potential space missions to comets, icy moons, and ring systems. This collisional phenomenology is relevant to fly-by capture and return of samples from planetary targets, and landing on icy surfaces. Previous efforts in the area of ice particle impact response have addressed approximately 3 mm diameter ice spheres near the elastic/inelastic transition speed, approximately 10 m/s (Higa et al, 1998). The present work describes development of specially designed experiments to enable imaging of the fragmentation behavior of 3 mm diameter (nominal) ice spheres at significantly greater impact speeds ( approximately 20-120 m/s) and normal (0 degrees ) and glancing (30 degrees , 45 degrees and 60 degrees ) impacts for the first time. The imaging of the high speed impacts was achieved through precise synchronization of an ice particle dispenser, a rotating polished aluminum alloy impact surface representing the spacecraft, and a high-speed camera.

Sharp AN - 1700099296; 2015-070577 AB - The Curiosity rover is exploring Gale crater and Mt. Sharp, Gale's 5-km high central mound. We are investigating the history of alteration and erosion of Mt. Sharp using orbital imagery, spectroscopy and rover observations. Our results suggest a significant time gap between emplacement of the upper and lower sections of the mound. Crater counts show that the lower mound was formed soon after Gale itself, and that it contains distinct units ranging in altitude from approximately -4,500 to -1,800 m. Spectral data suggest that many units contain phyllosilicates. We found that these clay-bearing rocks occur in distinct layers concentrated below -2,900 m. Parts of the lower mound exhibit a transition from clays to sulfates with increasing altitude. The lower mound shows evidence of flowing water, including canyons and inverted channels. Wind erosion produced km-scale yardangs and scalloped cliffs. Our mapping shows that many yardangs in the lower mound are clay-bearing, with a predominant orientation of around N-S. Curiosity's ground-level images show myriad fine-scale, mainly horizontal layers in the lower mound. The rover has found stream beds and conglomerates, indicating that water once flowed on the crater floor. Drilling near the deepest point in Gale produced abundant clay, providing additional evidence of aqueous alteration. Upper mound units range in altitude from -2,100 m to +500 m, and mantle the lower mound above an angular unconformity. Most upper mound units are composed of layers. The formation age of the upper mound is unknown, since few craters are preserved. Clay-bearing layers are detectable in several locations, mainly at altitudes near -2,000 m. There is no evidence of water flow, but wind erosion has scalloped the surfaces and edges of layers, and fine-scale yardangs are common. Correlations between yardangs and clay spectra are apparent only in the lowermost units of the upper mound. Yardang orientations vary, and include N-S, NW-SE, and NE-SW. Upper mound units resemble the planet-wide Medusae Fossae formation, dated as Hesperian and argued to be composed of ignimbrites. Medusae Fossae layers are easily eroded by wind, and our mapping demonstrates their resemblance to upper mound fine-scale yardangs. The history of Mt. Sharp started with deposition and lithification of sediments shortly after crater formation. Some lower mound layers were partially altered to clays and sulfates, and water formed streams and canyons. Wind erosion of the lower mound produced large-scale yardangs, particularly in clay-rich layers, oriented generally N-S. Upper mound units were emplaced following a considerable period of wind erosion. The absence of water flow on the upper mound suggests that these units were emplaced after atmospheric loss rendered water unstable at the surface. The shift in dominant wind direction, as indicated by yardang orientations, also argues for a time gap between erosion of the lower and upper mound. These observations are consistent with upper mound units being related to the Hesperian Medusae Fossae formation. During 2014 Curiosity is expected to reach the foot of Mt. Sharp and ascend through the clay-rich layers, into the sulfate-rich layers, and possibly past the interface with the upper mound. This will be a unique opportunity to field check geologic models on the surface of Mars.

Sufficient radiance is typically available to produce a vertical distribution of dust and water ice aerosols from the surface to approximately 50 km altitude. Radiative transfer modeling is conducted to achieve a best fit between the observed and modeled spectrum. The spherical geometry of the limb-viewing geometry is handled using a pseudo-spherical approximation that is computationally efficient and accurate to within a few percent of a Monte Carlo method for the geometries observed. Different particle sizes of dust and water ice have unique extinction coefficients across the visible and near-infrared portion of the spectrum observed by CRISM. We use a wide range of wavelengths across the CRISM spectrum to conduct the retrieval. Here we provide initial results on the retrieval of dust and water ice particle sizes over the duration of the CRISM limb-viewing observations.

Relating observations of potential pyroclastic deposits to source locations and eruption conditions requires a detailed quantitative understanding of the settling rates of individual particles under changing ambient conditions. For atmospheres that are well described by continuum mechanics, the conventional Newtonian description of particle motion allows particle settling velocities to be related to particle characteristics via a drag coefficient. However, under rarefied atmospheric conditions (i.e., on Mars and at high altitude on Earth), non-continuum effects become important for ash-sized particles, and an equation of motion based on statistical mechanics is required for calculating particle motion. We have developed a rigorous new treatment of particle settling under variable atmospheric conditions and applied it to Earth and Mars. When non-continuum effects are important (as dictated by the mean free path of atmospheric gas relative to the particle size), fall velocities are greater than those calculated by continuum mechanics. When continuum conditions (i.e., higher atmospheric densities) are reached during descent, our model switches to a conventional formulation that determines the appropriate drag coefficient as the particle transits varying atmospheric properties. The variation of settling velocity with altitude allows computation of particle trajectories, fall durations and downwind dispersal. Our theoretical and numerical analyses show that several key, competing factors strongly influence the downwind trajectories of ash particles and the extents of the resulting deposits. These factors include: the shape of the particles (non-spherical particles fall more slowly than spherical particle shapes commonly adopted in settling models); the formation of particle aggregates, which enhances settling rates; and the lagging of particle motion behind the ambient wind field, which results in less widely dispersed deposits. Above all, any particles experiencing non-continuum effects settle faster and are less widely dispersed than particles falling in an entirely continuum regime. Our model results demonstrate the complex interplay of these factors in the Martian environment, and our approach provides a basis for relating deposits observed in planetary datasets to candidate volcanic sources and eruption conditions. This allows for a critical reassessment of the potential for explosive volcanism to contribute to extremely widespread, fine-grained, layered deposits such as the Medusae Fossae Formation.

Gas Chromatography Mass Spectrometry (GC-MS) is currently the most relevant space-compatible analytical tool for the detection of organic compounds. Nevertheless, GC separation is intrinsically restricted to volatile molecules, and many molecules of astrobiological interest are chromatographically refractory or polar. To analyze these organics such as amino acids, nucleobases and carboxylic acids in the Martian regolith, an additional derivatization step is required to transform them into volatile derivatives that are amenable to GC analysis. As part of the Sample Analysis at Mars (SAM) experiment onboard Mars Science Laboratory (MSL) Curiosity rover, a single-step protocol of extraction and chemical derivatization with the silylating reagent N-methyl-N-(tert-butyldimethylsilyl)-trifluoroacetamide (MTBSTFA) has been developed to reach a wide range of astrobiology-relevant refractory organic molecules (Mahaffy et al. 2012; Stalport et al. 2012). Seven cups in the SAM instrument are devoted to MTBSTFA derivatization. However, this chemical reaction adds a protective silyl group in place of each labile hydrogen, which makes the molecule non-identifiable in common mass spectra libraries. Therefore, we have created an extended library of mass spectra of MTBSTFA derivatized compounds of interest, considering their potential occurrence in Mars soils. We then looked specifically for MTBSTFA derivatized compounds using the existing and the newly created library, in various Mars analog soils. To enable a more accurate interpretation of the in situ derivatization GC-MS results that will be obtained by SAM, the lab experiments were performed as close as possible to the SAM flight instrument experimental conditions. Our first derivatization experiments display promising results, the laboratory system permitting an extraction and detection of several proteinogenic amino acids and carboxylic acids from Martian analog materials. Preliminary results show a lack of derivatized organic molecules in hydrated solid samples however, where the MTBSTFA reagent possibly reacts preferentially with the water from hydrated minerals (Stalport et al. 2012). This result shows the importance of a complete understanding of the MTBSTFA reaction depending on the nature of the soil and will help guide the selection of optimal samples for the SAM wet chemistry on Mars.

The sediments consist of typical basalt minerals (Fe-forsterite, augite, pigeonite, plagioclase), as well as Fe oxide/hydroxides, Fe-sulfides, amorphous material, and a phyllosilicate. The phyllosilicate has a broad 001 peak at approximately 1.0 nm, consistent with a poorly ordered smectite. However, in the absence of diagnostic tests possible on Earth, its identity is not clear. The position of the 06L diffraction band is generally used to distinguish dioctahedral from trioctahedral smectite, but it is beyond CheMin's range of 2theta . The measured position of the 02L diffraction band ( approximately 22.5 degrees 2theta by CheMin), implies that the smectite is trioctahedral. The exact position and shape of the 02L band is determined by the cations in the 'M' sites of the smectite; to constrain those cations, we sought analogs among terrestrial smectites, emphasizing those developed from basaltic precursors. A potential analog for the Sheepbed smectite is 'griffithite,' a variety of trioctahedral smectite in altered basalt of the Topanga formation, Griffith Park, Los Angeles. 'Griffithite' has an 02L diffraction band that is close in position and shape to that of the Sheepbed smectite, although 'griffithite' has a very sharp 001 peak, indicating a high degree of layer ordering not seen in the Sheepbed smectite. A typical chemical formula for 'griffithite,' determined by electron microprobe, is (Ca0.59 Na0.03) (Mg4.28 Fe1.83) (Si6.64 Al1.36) O20 (OH)4, normalized to Si+Al=8. This formula is consistent with a fully trioctahedral Fe-Mg smectite with Ca and Na as interlayer cations. In the Topanga basalt, four types of 'griffithite' are present: fine-grained, filling cracks and vesicles; coarse-grained, filling vesicles; coarse-grained, replacing olivine phenocrysts; and coarse-grained, replacing glassy mesostasis. The fine-grained 'griffithite' formed first, and the last three varieties may be contemporaneous. One sample shows agate (alpha -quartz) that was precipitated between the episodes of deposition of the fine-grained and coarse-grained 'griffithite.' 'Griffithite' is not unique as a possible terrestrial analog - some clay minerals from the Doushantou formation, China, have similar 02L diffraction bands, and many basalts contain smectites in vesicles and as replacements after olivine. Similar trioctahedral smectites occur also in the nakhlite martian meteorites - as veinlets and replacements of olivine. By understanding the formation of these terrestrial clays, we hope to constrain the nature and mechanism of formation of the Sheepbed clay mineral.

YKB lies in a distal region of the Peace Vallis alluvial fan, which extends from the northern rim of Gale Crater toward the dune field at the base of Mt Sharp. Sedimentological and stratigraphic observations are consistent with the Yellowknife Bay formation being part of a distal fan deposit, which could be as young as middle Hesperian to even early Amazonian in age ( approximately 3.5 to 2.5 Ga). The Yellowknife Bay formation hosts a unit of mudstone called the Sheepbed member. Curiosity obtained powdered rock samples from two drill holes in the Sheepbed Member, named John Klein and Cumberland, and delivered them to instruments in Curiosity. Data from CheMin, a combined X-ray diffraction (XRD)/X-ray fluorescence instrument (XRF), has allowed detailed mineralogical analysis of mudstone powders revealing a clay mineral component of approximately 20 wt.% in each sample. The clay minerals are important indicators of paleoenvironmental conditions and sensitive recorders of post-depositional alteration processes. The XRD pattern of John Klein reveals a 02l band consistent with a trioctahedral phyllosilicate. A broad peak at approximately 10A with a slight inflexion at approximately 12A indicates the presence of 2:1 type clay minerals in the John Klein sample. The trioctahedral nature of the clay minerals, breadth of the basal reflection, and presence of a minor component with larger basal spacing suggests that John Klein contains a trioctahedral smectite (probably saponite), whose interlayer is largely collapsed because of the low-humidity conditions. The XRD patterns show no evidence of corrensite (mixed-layer chlorite/smectite) or chlorite, which are typical diagenetic products of trioctahedral smectites when subjected to burial and heating >60 degrees C in the presence of water. Given estimated geothermal gradients on Mars temperatures <60 degrees C might still be consistent with (but do not require) moderate burial. However, our ability to identify interstratified minerals is greatly limited by the lack of access to traditional treatments methods used in the lab (e.g., ethylene glycol solvation). Our preferred explanation for the origin of trioctahedral smectites in Sheepbed mudstone is in situ production via reaction of olivine, water and Si-bearing amorphous material, an important mudstone component detected by XRD. Elevated levels of magnetite in the Sheepbed and the trioctahedral monomineralic nature of the clay minerals support this model. These observations, combined with previous studies of olivine stability, support the persistence of circum-neutral hydrous conditions for thousands of years at YKB.

Fundamental questions, as promoted in recent VEXAG documents, include: (1) Did Venus, Mars, and Earth have a common origin? (2) What roles did comets from the outer Solar System play in delivering volatiles to Venus? (3) Did Venus once have and lose a global ocean? (4) How much has Venus outgassed, and what is the current rate of outgassing, particularly of sulfur, the major driver of Venus clouds? and (5) Through the deposition of energy within them, what role do these clouds play in (a) driving the cloud-level thermal structure and (b) generating and maintaining the super-rotating zonal windfield that covers the globe? Fundamental answers could be uniquely provided through in-situ sampling via mass spectrometry of the noble gases and their isotopes - in particular of the 8 stable Xe isotopes, the bulk abundances of Kr, and the 3 isotopes of Ne. Measurements of the relative abundances of the light isotopes of N, O, H, S and O, by, for example, tunable laser spectrometry, would provide additional insights into Venus's origin, surface outgassing and planetary escape. Such measurements could be performed by probes, landers, or balloons. On descent through the uv-absorbing layer and the surrounding H2SO4 cloud, each of these platforms could explore both the absorber and sulfur-cycle-associated reactive species and aerosols, thus addressing VEXAG desires for enhanced understanding of Venus' chemical cycles, aerosol properties, and radiative transfer. On descent to the surface, probes and landers can provide vertical profiles of temperatures and species abundances, as well as provide near-surface measurements of sulfur isotopes and trace sulfuric gases indicative of outgassing. Additional major in-situ goals dealing with Venus's global circulation and local dynamics can be addressed by a balloon platform floating within the convective middle cloud near approximately 55-km altitude. Drifting over a wide range of latitudes and all times-of-day and longitudes, such a floating platform could accurately measure (1) motions in all three dimensions--zonal, meridional, and vertical, including motions associated with convection and gravity waves, (2) simultaneous measurements of cloud particle size, their parent molecules, the local temperature, and vertical velocity, to study cloud formation/dissipation processes, and (3) the power and frequency of local lightning. Altogether, such in-situ measurements would potentially revolutionize our understanding of (1) Venus's circulation, including the role of waves and solar cloud heating in powering the planet's poorly-understood super-rotation, (2) Venus's sulfur cycle, key to Venus's current climate, and (3) how Earth's neighbor formed and evolved over the aeons.

Recent modeling studies (e.g. Pavlov et al., 2012) suggested that organic molecules with masses >100 amu would be degraded in less than 1 billion years in the top 5 cm of the Martian rocks. That poses a serious challenge to the search of ancient molecules in the shallow subsurface of Mars. However, Pavlov et al. calculated the fraction of the survived organic molecules using conservative radiolysis constants derived from the gamma irradiation experiments on pure dry amino acid mixtures (Kminek and Bada, 2006). In this study we conducted a series of gamma irradiations of amino acids and carboxylic acids mixed with silica powder. We report that the addition of silicates dramatically increased the rate of organic degradation under gamma radiation. Using the newly derived radiolysis constants for amino acids and carboxylic acids in mineral mixtures, we recalculated the rate of organic degradation in the Martian rocks as a function of rocks' depth, chemical composition and weathering rates. Our results suggest that isolated organic molecules (acids) are likely to be altered or fully degraded in the surface rocks on Mars by cosmic rays in less than 10 million years unless some additional protective mechanisms are in place. We will discuss possible strategies for the MSL's search of the elusive ancient organic molecules to overcome the adverse effects of cosmic rays in the surface Martian rocks.

Specifically, the brightness of the sky as a function of angle away from the Sun provides a powerful constraint on the size distribution and shape of dust and water ice aerosols. More than 100 Pancam "sky surveys" were taken by each of the two MER rovers covering a time span of several Mars years and a wide range of dust loading conditions including the planet-encircling dust storm during Mars Year 28 (Earth year 2007). These sky surveys enable the time evolution of aerosol particle size to be determined including its relation to dust loading. Radiative transfer modeling is used to model the observations. Synthetic Pancam sky brightness is computed using a discrete-ordinates radiative transfer code that accounts for multiple scattering from aerosols and spherical geometry by integrating the source functions along curved paths in that coordinate system. We find that Mie scattering from spheres is not a good approximation for describing the angular variation of sky brightness far from the Sun (at scattering angles greater than 45 degrees). Significant seasonal variations are seen in the retrieved effective radius of the aerosols with higher optical depth strongly correlated with larger particle size.

The time series of dose rate for the first 300 Sols after landing on Mars on August 6, 2012 is presented here. For the comparison to RAD measurements of dose rate, Martian surface ionization radiation is simulated by utilizing observed space quantities. The GCR primary radiation spectrum is calculated by using the Badhwar-O'Neill 2011 (BO11) galactic cosmic ray (GCR) model, which has been developed by utilizing all balloon and satellite GCR measurements since 1955 and the newer 1997-2012 Advanced Composition Explorer (ACE) measurements. In the BO11 model, solar modulation of the GCR primary radiation spectrum is described in terms of the international smoothed sunspot number and a time delay function. For the transport of the impingent GCR primary radiation through Mars atmosphere, a vertical distribution of atmospheric thickness at each elevation is calculated using the vertical profiles of atmospheric temperature and pressure made by Mars Global Surveyor measurements. At Gale Crater in the southern hemisphere, the seasonal variation of atmospheric thickness is accounted for the daily atmospheric pressure measurements of the MSL Rover Environmental Monitoring Station (REMS) by using low- and high-density models for cool- and warm-season, respectively. The spherically distributed atmospheric distance is traced along the slant path, and the resultant directional shielding by Martian atmosphere is coupled with Curiosity vehicle for dose estimates. We present predictions of dose rate and comparison to the RAD measurements. The simulation agrees to within +-20% with the RAD measurements showing clearly the variation of dose rate by heliospheric conditions, and presenting the sensitivity of dose rate by atmospheric pressure, which has been found from the RAD experiments and driven by thermal tides on Martian surface.

A nitrogen cycle may exist on Mars where nitrates, produced early in Mars' history, may have been later decomposed back into N (sub 2) by the current impact flux. Nitrates are a fundamental source of nitrogen for terrestrial microorganisms, and they have evolved metabolic pathways to perform both oxidation and reduction to drive a complete biological nitrogen cycle. Therefore, the characterization of nitrogen in Martian soils is important to assess habitability of the Martian environment, particularly with respect to the presence of nitrates. The only previous mission that was designed to search for soil nitrates was the Phoenix mission but N-containing species were not detected by TEGA or the MECA WCL. Nitrates have been tentatively identified in Nakhla meteorites, and if nitrogen was oxidized on Mars, this has important implications for the habitability potential of Mars. Here we report the results from the Sample Analysis at Mars (SAM) instrument suite aboard the Curiosity rover during the first year of surface operations in Gale Crater. Samples from the Rocknest aeolian deposit and sedimentary rocks (John Klein) were heated to approximately 835 degrees C under helium flow and the evolved gases were analyzed by MS and GC-MS. Two and possibly three peaks may be associated with the release of m/z 30 at temperatures ranging from 180 degrees C to 500 degrees C. M/z 30 has been tentatively identified as NO; other plausible contributions include CH (sub 2) O and an isotopologue of CO, (super 12) C (super 18) O. NO, CH (sub 2) O, and CO may be reaction products of reagents (MTBSTFA/DMF) carried from Earth for the wet chemical derivatization experiments with SAM and/or derived from indigenous soil nitrogenated organics. Laboratory analyses indicate that it is also possible that <550 degrees C evolved NO is produced via reaction of HCl with nitrates arising from the decomposition of perchlorates. All sources of m/z 30 whether it be martian or terrestrial will be considered and their implications for Mars will be discussed.

Important questions remain regarding the origin and evolution of the atmosphere, the history of the surface and interior, and how the surface and atmosphere interact. In a broader context, understanding Venus has implications for understanding the evolution of terrestrial planets in our Solar System as well as for interpreting the growing set of observations of extra-solar planets. The Venus Exploration Analysis Group (VEXAG), established in 2005, is chartered by NASA's Planetary Science Division and reports its findings to the NASA Advisory Council. Open to all interested scientists, VEXAG regularly evaluates Venus exploration goals, scientific objectives, investigations and critical measurement requirements, including especially recommendations in the NRC Decadal Survey and the Solar System Exploration Strategic Roadmap. At the last general meeting in November 2012, VEXAG resolved to update the scientific priorities and strategies for Venus exploration. To achieve this goal, three major tasks were defined for 2013, (1) update the document prioritizing Goals, Objectives and Investigations for Venus Exploration, (2) develop a Roadmap for Venus exploration that is consistent with VEXAG priorities as well as Planetary Decadal Survey priorities, and (3) develop a white paper on technologies for Venus missions. Proposed versions of all three documents were presented at the VEXAG general meeting in November 2013. Here, we present the findings and final versions of all three documents for community comment and feedback. A follow-on Workshop on Venus Exploration Targets is also being planned for the early summer of 2014. The workshop will provide a forum for the Venus science community to discuss approaches for addressing high priority investigations. Participants will be encouraged to present their ideas for specific targets on Venus (interior, surface and atmosphere) as well as to present specific data requirements (measurement type, resolution, precision, etc.) needed to answer key questions.

We review the evidence of mid-latitude ground ice on Mars, review the possible explanations for its occurrence, and then consider the potential for this ground ice to be a recent habitat for life. We systematically analyze Mars remote sensing datasets to determine if a viable landing site exists to fulfill the science, human exploration, and engineering criterions to support a Mars life detection mission. We classify each site according to 1) presence of polygons as a proxy for subsurface ice, 2) presence and abundance of rough topographic obstacles (e.g., large cracks, cliffs, uneven topography, etc.), 3) rock density, 4) presence and abundance of large boulders, and 5) presence of craters. We find that a suitable landing site exists within Amazonis Planitia which is adjacent to a recently excavated crater harboring water ice in the near subsurface. Thus a Mars life detection mission can be flown and executed at an ice-rich landing site on Mars consistent with the predefined mission constraints.

SAM analyses, which heated the mudstone samples to 1000oC and monitored volatiles evolved to perform in situ evolved gas analysis mass spectrometry (EGA-MS), resulted in a H2O trace exhibiting a wide evolution at temperatures <500oC, and an evolution peak at higher temperatures near approximately 750oC. The low temperature H2O evolution has many potential contributors, including adsorbed H2O, smectite interlayer H2O, and structural H2O/OH from bassanite and akaganeite (identified by CheMin) and H2O/OH from amorphous phases in the sample. The high temperature H2O is consistent with the evolution of H2O from the dehydroxylation of the smectite clay mineral. Comparison to EGA-MS data collected under SAM-like conditions on a variety of clay mineral reference materials indicate that a trioctahedral smectite, such as saponite, is most consistent with the high temperature H2O evolution observed. There may also be SAM EGA-MS evidence for a small high temperature H2O evolution from scoop samples from the Yellowknife Bay Rocknest sand shadow bedform. As in the mudstone samples, this evolution may indicate the detection of smectite clays, and the idea that minor clays may be present in Rocknest materials that could be expected to be at least partially derived from local sources is reasonable. But, because smectite clays were not definitively observed in CheMin analyses of Rocknest materials, they must be present at much lower abundances than the DF20% observed in the mudstone samples. This potential detection underscores the complementary nature of the MSL CheMin and SAM instruments for investigations of martian sample mineralogy. Information on the nature of Yellowknife Bay clay minerals may also be available from the detection of H2 evolved during SAM EGA-MS at high temperature. A likely source of at least some of this H2 is H2O evolved from the smectite clays at high temperature, and it is possible these evolutions can be used in a similar fashion to high temperature H2O releases to provide constraints on the clay minerals in a sample. In addition, the D/H of this high temperature H2, as well as the H2O, can be derived from SAM MS and Tunable Laser Spectrometer (TLS) data, respectively. These D/H values may help to inform the provenance of high and low temperature water evolved from martian samples (Mahaffy et al., this meeting).

Their abundance and stable isotopic ratios are also indicative of sources as well. The Sample Analysis at Mars (SAM) investigation on the Curiosity rover has measured the Martian atmosphere and reported on the volume mixing ratio of its major constituents (Mahaffy et al., 2013). Here we report the abundance and isotopic ratios of Kr and Xe in the atmosphere of Mars as obtained by semi-static operation of the SAM quadrupole mass spectrometer. Viking provided the first in situ detection of these gases (Owen et al, 1977), suggesting upper limits of 300 ppb for Kr and 80 ppb for Xe, based upon calibration gases with terrestrial isotopic abundances. The abundances of individual isotopes as well as their ratios to one another have been derived from martian meteorite samples by many investigators (e.g., Becker & Pepin, 1984; Bogard & Garrison, 1998). The SAM heavy noble gas data complement the argon isotopic data reported in Mahaffy et al., 2013. Becker, R. H., & Pepin, R. O. (1984).

A primary mission science objective is to search for past habitable environments, and, in particular, to assess the role of past water. Identifying the minerals and mineraloids that result from aqueous alteration at Gale crater is essential for understanding past aqueous processes at the MSL landing site and hence for interpreting the site's potential habitability. X-ray diffraction (XRD) data from the CheMin instrument and evolved gas analyses (EGA) from the SAM instrument have helped the MSL science team identify phases that resulted from aqueous processes: phyllosilicates and amorphous phases were measure in two drill samples (John Klein and Cumberland) obtained from the Sheepbed Member, Yellowknife Bay Fm., which is believed to represent a fluvial-lacustrine environment. A third set of analyses was obtained from scoop samples from the Rocknest sand shadow. Chemical data from the APXS instrument have helped constrain the chemical compositions of these secondary phases and suggest that the phyllosilicate component is Mg-enriched and the amorphous component is Fe-enriched, relatively Si-poor, and S- and H-bearing. To refine the phyllosilicate and amorphous components in the samples measured by MSL, we measured XRD and EGA data for a variety of relevant natural terrestrial phyllosilicates and synthetic mineraloids in laboratory testbeds of the CheMin and SAM instruments. Specifically, Mg-saturated smectites and vermiculites were measured with XRD at low relative humidity to understand the behavior of the 001 reflections under Mars-like conditions. Our laboratory XRD measurements suggest that interlayer cation composition affects the hydration state of swelling clays at low RH and, thus, the 001 peak positions. XRD patterns of synthetic amorphous materials, including allophane, ferrihydrite, and hisingerite were used in full-pattern fitting (FULLPAT) models to help determine the types and abundances of amorphous phases in the martian rocks and sand shadow. These models suggest that the rocks and sand shadow are composed of approximately 30% amorphous phases. Sulfate-adsorbed allophane and ferrihydrite were measured by EGA to further understand the speciation of the sulfur present in the amorphous component. These data indicate that sulfate adsorbed onto the surfaces of amorphous phases could explain a portion of the SO2 evolution in the Rocknest SAM data. The additional constraints placed on the mineralogy and chemistry of the aqueous alteration phases through our laboratory measurements can help us better understand the nature of the fluids that affected the different samples and devise a history of aqueous alteration for the Sheepbed Member of the Yellowknife Bay Fm. at Gale crater.

The presence of pitted terrain at the floors of craters on Vesta has been ascribed to the release of volatiles during impact, following the discovery of similar features on Mars where they are interpreted as volatile-rich impact melt deposits. The numerous dark regions and the H abundance have been ascribed to the presence of infall material resembling CM chondrites. CM chondrite clasts are relatively common in brecciated meteorites, including the HED meteorites that are presumed to have come from Vesta (or Vesta fragments), and contain up to about 10 vol% water. On the walls of craters associated with the pitted terrain in craters, but also observed outside craters, are features resembling gullies. The nature of these features, the amount of fluids required, and, especially, the relationship between the pits and gully-like features is unclear. Pit-like structures are commonly observed at terrestrial impact craters (hydrothermal pipes) and in volcanic fields (phreatic craters) in which water was present during the active phases of these processes. They are usually well-studied and offer a range of "ground truths" which might help us understand the features on Vesta. The number, morphology, and locations of the features provide temporal information on their histories. The number, size and distribution of boulders around the features, provides information on energetics and water content. We expect such structures to be present in water-bearing C and X asteroids, where the water in endogenous, and S asteroids where, like Vesta, the water is exogenous. Such features, if present, were generally obscured by regolith on Eros, but a search in regolith-poor areas might be worthwhile. In summary, we suggest that new insights into volatile behavior on near-Earth asteroids, with its relevance to geological evolution, astrobiology, and space resources, will be possible through the study of terrestrial analogs.

We present a disk-integrated compositional analysis of the Martian satellite. The area studied in this work covers from 126 degrees W to 286 degrees W in longitude and from 86.8 degrees N to 90 degrees S in latitude and it was observed with a phase angle ranging from 18.87 degrees to 18.95 degrees . Previous investigations of the composition of the surface of Phobos made use of spectral matching. In our study we undertake spectral modeling of the surface of Phobos albedo using a radiative transfer code based on the slab approximation. The code calculates the albedo of a powdered surface from the optical constants of candidate materials. After scaling the OSIRIS data to match a previously obtained visible albedo measurement, we provide spectral modeling of the surface of Phobos in the wavelength range between 0.25 and 4.0 mu m, using OSIRIS and the Rivkin et al. (Rivkin, A. S. et al., 2002, Icarus, 156, 64) IRTF results. We provide two models, the first one fitting better the OSIRIS data and yielding a composition that includes organic carbonaceous material, serpentine, olivine, and basalt glass. The presence of organic material makes this model questionable as it produces a strong absorption at 3.0 mu m not seen in previously obtained Phobos data. Our second model was fit to the OSIRIS data extended in wavelength to include the Rivkin et al. (2002) data. We modeled the OSIRIS data using Tagish Lake meteorite optical constants, and our best fitting model in this case consists of Tagish Lake and magnesium-rich pyroxene glass. The overall shape of the second model spectrum fits over a large wavelength range and shows that both curvature and albedo level match the OSIRIS and Rivkin et al. (2002) data much better than the first model did. While both models contain complex organic molecular material, Tagish Lake seems to have a composition and/or molecular structure that yields a better fit, particularly in view of the fact that it is a naturally occurring material rather than a synthetic one as the tholin. This gives weight to this model making it our most promising fit for Phobos. Since Tagish Lake is commonly used as a spectral analog for D-type asteroids, this provides additional support for compositional similarities of Phobos and D-type asteroids. All these factors are consistent with Phobos being a captured D-type asteroid as previously suggested by Rivkin et al. (2002) and Pajola et al. (Pajola, M. et al., 2012, MNRAS, 427, 3230) who presented an updated scenario based on the collisional capture mechanism of Phobos.

Previous work has shown that the Earth's Moon stabilizes Earth's obliquity such that it remains within a narrow range, between 22.1 degrees and 24.5 degrees . Without lunar influence, a frequency-map analysis by Laskar et al. (Laskar, J., Joutel, F., Robutel, P. [1993]. Nature 361, 615-617) showed that the obliquity could vary between 0 degrees and 85 degrees . This has left an impression in the astrobiology community that a large moon is necessary to maintain a habitable climate on an Earth-like planet. Using a modified version of the orbital integrator mercury, we calculate the obliquity evolution for moonless Earths with various initial conditions for up to 4 Gyr. We find that while obliquity varies significantly more than that of the actual Earth over 100,000 year timescales, the obliquity remains within a constrained range, typically 20-25 degrees in extent, for timescales of hundreds of millions of years. None of our Solar System integrations in which planetary orbits behave in a typical manner show obliquity accessing more than 65% of the full range allowed by frequency-map analysis. The obliquities of moonless Earths that rotate in the retrograde direction are more stable than those of prograde rotators. The total obliquity range explored for moonless Earths with rotation periods shorter than 12 h is much less than that for slower-rotating moonless Earths. A large moon thus does not seem to be needed to stabilize the obliquity of an Earth-like planet on timescales relevant to the development of advanced life.

There is very little previous knowledge of meteoroids in the outer solar system, and no direct knowledge of particles in the size range probed by this work (larger than dust but smaller than moons). The observed dusty clouds are due to impacts onto the rings that occurred between 1 and 50 hours before the clouds were observed. The largest of these clouds was observed twice; its brightness and cant angle evolved in a manner consistent with this hypothesis. Several arguments suggest that these clouds cannot be due to the primary impact of one solid meteoroid onto the rings, but rather to the impact of a compact stream of Saturn-orbiting material derived from previous breakup of a meteoroid. The responsible interplanetary meteoroids were initially between 1 cm and several meters in size, and their influx rate is consistent with the sparse prior knowledge of smaller meteoroids in the outer solar system.

These fans lie within enclosed crater basins, and are characterized by their large size (tens of km in length) and gentle gradient (less than 1-3 degrees ). The fans generally feature a network of channel distributaries floored with coarser sediment and what we have interpreted to be fine grained overbank deposits that comprise the bulk of the fan material. We have developed a landform evolution model based on an approach to simulate the growth of these fans in order to answer several questions about their formation, including: (1) what are the characteristics of water discharge (flow magnitude and duration) and sediment supply (quantity and grain size); and (2) what are the associated implications for the responsible climatic environment (e.g. amount and frequency of precipitation sourcing the fans). The model combines discharge and sediment deposition with channel avulsion and abandonment, allowing for an analysis of both the micro and macro scale processes concerning fan formation. Water and sediment is routed through a distributary network that can branch, recombine, and avulse. The model simulates deposition of both coarse-grained bedload and a fine-grained suspended load material that can be deposited overbank during flood events. The model records the stratigraphy of the deposited material in terms of the relative proportions of coarse and fine-grained sediment. Using measures such as channel width, relative proportions of channel versus overbank deposited sediment, and frequency of channel branching, output is statistically compared with digital elevation models that have been produced from high-resolution CTX and HiRISE stereo pairs. Initial results suggest fans formed from hundreds of flow events over many thousands of years. Fan formation processes appear to be similar to those active in terrestrial fans in northern Chile's Atacama Desert. Additional model runs will simulate fan development under different patterns of precipitation (uniform over the fan versus an orographic pattern of greater precipitation on upper crater walls) and variations in sediment size distribution.

The Moon responds elastically by deforming into an ellipsoid that is slightly squashed along the limb and bulged on the near and far sides, with a maximum radial displacement of approximately 50 cm (with respect to a perfect sphere) near the sub-Earth point and its antipode. Variations in the Earth-Moon distance and geometric librations cause the bulge pattern to fluctuate in amplitude and shift in position on the surface, so that the surface height at any given geographic location moves up and down with a dominant period of 27.555 days and an amplitude of up to approximately 10 cm. Studying the detailed shape and behavior of these deformations can yield important information on the Moon's physical properties, such as the density distribution and bulk elastic parameters. After approximately 4.5 years of operation, the Lunar Orbiter Laser Altimeter (LOLA) aboard the Lunar Reconnaissance Orbiter (LRO) has collected over 6 billion measurements of surface height with a vertical precision of approximately 10 cm and an accuracy of approximately 1 m. The LOLA dataset contains more than 10 million crossovers, instances when two ground-tracks intersect. Each crossover represents the measurement of surface height at one location and at two different times, thereby providing a way of measuring tidal deformations. Here we present preliminary results of efforts to detect and constrain lunar tidal deformations using a sample of the highest-quality LOLA crossovers.

MOMA will examine the chemical composition of samples acquired from depths of up to two meters below the martian surface, where organics may be protected from radiative and oxidative degradation. When combined with the complement of instruments in the rover's Pasteur Payload, MOMA has the potential to reveal the presence of a wide range of organics preserved in a variety of mineralogical environments, and to begin to understand the structural character and potential origin of those compounds. MOMA includes an ion trap mass spectrometer (ITMS) that is designed to analyze molecular composition of (i) gas evolved from pyrolyzed powder samples and separated on a gas chromatograph and (ii) ions directly desorbed from solid samples at Mars ambient pressure using a pulsed laser and a fast-valve capillary ion inlet system. This "dual source" approach gives MOMA unprecedented breadth of detection over a wide range of molecular weights and volatilities. Analysis of nonvolatile, higher-molecular weight organics such as carboxylic acids and peptides even in the presence of significant perchlorate concentrations is enabled by the extremely short ( approximately 1 ns) pulses of the desorption laser. Use of the ion trap's tandem mass spectrometry mode permits selective focus on key species for isolation and controlled fragmentation, providing structural analysis capabilities. The flight-like engineering test unit (ETU) of the ITMS, now under construction, will be used to verify breadboard performance with high fidelity, while simultaneously supporting the development of analytical scripts and spectral libraries using synthetic and natural Mars analog samples guided by current results from MSL. ETU campaign data will strongly advise the specifics of the calibration applied to the MOMA flight model as well as the science operational procedures during the mission.

In particular, acidic terrestrial ecosystems arose from the oxidation of reduced species in hydrothermal settings and crustal reservoirs of metal sulfides, creating acid sulfate conditions. While oxidation of reduced species is facilitated by reactions with molecular oxygen, acidic conditions also arose in Archean hydrothermal systems before the rise of oxygen (Van Kranendonk, 2006), expanding the range of time over which acidophiles could have existed on the early Earth. Acidic terrestrial habitats would have included acidic hydrothermal springs, acid sulfate soils, and possibly lakes and streams lacking substantial buffering capacity with sources of acidity in their catchments. Although acidic hot springs are considered extreme environments on Earth, robust and diverse microbial communities thrive in these habitats. Such acidophiles are found across all three domains of life and include both phototrophic and chemotrophic members. In this presentation, we examine hopanes and sterols that are characteristic of microbial communities living in acidic hydrothermal environments. Moreover we discuss taphonomic processes governing the capture and preservation of these biosignatures in acid environments. In particular, we discuss the production and early preservation of hopanoids and sterols in the following geological/mineralogical settings: 1) rapid entombment of microbes and organic matter by predominantly fine-grained silica; 2) rapid burial of organic matter by clay-rich, silica poor sediments; 3) and the survival of organics in iron oxide and sulfate rich sediments. We discovered and isolated an acid-tolerant purple non-sulfur anoxygenic phototroph from Lassen Volcanic National Park that synthesizes 3 methyl-bacteriohopanepolyols. These compounds were previously thought to be exclusively made by methanotrophic and acetic acid bacteria. We also documented the production of unique patterns of abundance of C27, C28, and C29 sterols by the early diverging red and green algae Cyanidiales and Chlorella in the acidic outflow channel of Nymph Creek in Yellowstone National Park. Hydrothermal processes associated with volcanism are common features of ancient habitable environments on Earth and have been inferred for ancient Mars as well. Understanding the preservation of organics in modern acidic hydrothermal settings thus helps inform the detection of these compounds in the ancient sedimentary record on Earth, and perhaps Mars.

A search for organic biomarkers can address several questions including: 1) Evidence for present or past life, 2) Evidence for a second genesis of life, 3) Hazard assessment for human explorers and sample return and 4) Detection of bioload from Earth. Some useful analogs for the search for organic biomarkers on other worlds include 1) Ancient Earth sediment record, an example of a poorly preserved ancient biochemistry, 2) Modern environments including anoxic Antarctic sediments 3)Extreme cold desert surfaces in the High Antarctic Dry Valleys 4) Extremely dry soils such as the Atacama Desert 5) Evaporites.

Lunar Prospector and the Lunar Reconnaissance Orbiter (LRO), have shown that the energy distribution of albedo neutrons is modulated by the elemental composition of the lunar regolith], and by ice deposits in permanently shadowed polar craters. Here we investigate an analogous phenomenon with high energy lunar albedo protons. Using the CRaTER instrument (Cosmic Ray Telescope for the Effects of Radiation) on LRO, we measure albedo protons (60 to 150 MeV) to construct a cosmic ray albedo proton map of the Moon. Our current map is a significant improvement over the proof-of-concept map of Wilson et al. In addition to using more numerous minimum ionizing GCR protons for normalization, we filter out all solar particle enhancement periods and make use of all six of CRaTER's detectors to reduce contamination from spurious non-proton events in the data stream. The average yield of albedo protons from the maria is 0.8%+ or -0.4% higher than the yield from the highlands. In addition there appear to be localized peaks in the albedo proton yield that are co-located with peaks in trace elemental abundances as measured by the Lunar Prospector Gamma Ray Spectrometer. More data may reveal subtler proton yield variations correlated with latitude, time of day, or the locations of permanently shadowed craters, due to the presence of water frost. Given that the most obvious features in the map have a proton yield only 2sigma above average, the search for more subtle regions of enhancement or reduction in proton yield will require precise corrections for small but systematic effects of time and spacecraft altitude on the apparent proton yield. We will show the effects of these trends as well as the latest version of the albedo proton map.

The volatiles are liberated via surface energization processes associated with the harsh space environment, including solar wind plasma sputtering and impact vaporization. We demonstrate that such processes can transport cold-trapped volatiles to lower latitudes, possibly accounting for a portion of the mid-latitude water and OH veneer observed in the IR (the 3 micron absorption feature). We also demonstrate that some fraction of these volatiles can migrate from crater floors onto regions directly adjacent to the polar craters, and that the topside terrains should contain a sampling of the material originating within the crater itself. It is concluded that to derive volatile content in the crater, it may not be necessary to explore the cold, non-illuminated crater floors. Instead, the nature of the crater volatiles may be obtained by sampling the surface volatiles that have migrated or 'spilled out' onto the adjacent terrain. This 'spillage' effect could make human or robotic exploration of crater resources significantly easier, since an analysis may not require direct entry into the very harsh polar crater environment.

The Science Definition Team (SDT) for the proposed NASA Mars 2020 rover mission recently announced a suggested approach for NASA to "demonstrate significant technical progress towards the future return of scientifically selected, well-documented samples to Earth" in part "to investigate whether Mars was ever inhabited by microbial life." The SDT further recommended a per-sample volume of 8 cm (super 3) (e.g., a core with a diameter of 1 cm and length of 10 cm). Such samples would be the first available for scientific inquiry with the potential to definitively answer the fundamental question of astrobiology, and their small volume would necessitate analysis with non- or minimally destructive techniques. Potential biosignatures include "chemical, isotopic, mineralogical, and morphological features that can be created by life and also appear to be inconsistent with nonbiological processes". Guidelines for biosignature detection in extraterrestrial samples derive in part from the search for evidence of life in the most ancient sedimentary rocks on Earth, wherein the most compelling case for biogenicity is made when these "chemical, isotopic, mineralogical, and morphological features" occur in association. Sedimentary rocks deposited on Earth prior to approximately 3.5 billion years ago (i.e., when persistent surface water likely supported habitable environments on Mars) have only very rarely escaped severe alteration by metamorphism and metasomatism. Understanding how these processes have operated on Earth through strategic interrogation of biosignature alteration records in (meta)sedimentary rocks is thus a critical task in the search for extraterrestrial life. Here we present techniques for and results of in situ, spatially resolved, non- or minimally destructive detection of morphological, elemental, molecular, and light stable isotopic biosignatures, as well as records of alteration, in Precambrian sedimentary rocks from Earth in the context of the eventual analysis of samples returned from Mars. Sample acquisition and preparation, morphological analysis by conventional light, confocal laser, and electron microscopy, elemental analysis by energy and wavelength dispersive spectroscopy, molecular analysis by laser Raman microscopy, carbon isotope analysis of organic matter and carbonate minerals, and multiple sulfur isotope analysis of pyrite with secondary ion mass spectrometry will be discussed. New and recently published results from the application of these methods towards detection of the signatures of life, environment, and alteration history in rocks containing putative and bona fide microfossils ranging in age from 0.6 to 3.5 billion years, and in rocks of similar age lacking morphological biosignatures, as well as our current understanding of key challenges and opportunities for future research will be reviewed.

Atmospheric circulation modeling plays an important role in the characterization of these planets, helping to constrain observations that probe their atmospheres. These models have proven successful in understanding observations of transiting exoplanets (when the planet passes in front of the star along our line of sight) particularly when the planet is passing through secondary eclipse (when the planet's dayside is visible). In modeling super Earths and terrestrial exoplanets, we must consider not only planets with thick fluid envelopes, but also traditional terrestrial planets with solid surfaces and thinner atmospheres. To that end, we present results from studies investigating the atmospheric circulation of these classes of planets using the SPARC/MITgcm, a state-of-the-art model which couples the MIT General Circulation Model with a plane-parallel, two-stream, non-gray radiative transfer model. We will present results from two studies, the first focusing on the circulation of GJ 1214b, a super-Earth detected by the MEarth ground-based survey, and a second study which explores the circulation of terrestrial exoplanets orbiting M-dwarfs.

These observations range from multiple in-situ and orbital horizon glow detections to direct measurement of dust motion on the surface, as by the Apollo 17 Lunar Ejecta and Meteorites (LEAM) experiment. Despite this evidence, the specific mechanisms responsible for the lofting of regolith are still actively debated. These include impact ejection, electrostatic lofting, effects of high energy radiation, UV/X-rays, and interplay with solar wind plasma. These processes are highly relevant to one of the two main scientific objectives of the Lunar Atmosphere and Dust Environment Explorer (LADEE) mission (due to launch September, 2013): to directly measure the lunar exospheric dust environment and its spatial and temporal variability towards the goal of better understanding the dust flux. Of all the proposed mechanisms taking place on the lunar surface, the only unequivocal ongoing process is impact cratering. Hypervelocity impact events, which mobilize and redistribute regolith across planetary surfaces, are arguably the most pervasive geologic process on rocky bodies. While many studies of dust lofting state that the impact flux rate is orders of magnitude too low to account for the lunar horizon glow phenomenon and discount its contribution, it is imperative to re-examine these assumptions in light of new data on impact ejecta, particularly from the contributions from mesoscale (impactor size on the order of grain size) and macroscale (impactor>grain size) cratering. This is in large part due to a previous lack of data, for while past studies have established a canonical ejecta model for main-stage ejection of sand targets from vertical impacts, only recent studies have been able to begin quantitatively probing the intricacies of the ejection process outside this main-stage, vertical regime. In particular, it is the high-speed early-time ejecta that will reach significant altitude above the surface and remain aloft ballistically for hours. In addition, ejecta dynamics in the transition regime between microcratering and macro scale events is not yet well understood. As such, there is no currently accepted encompassing model of impact ejecta delivery to the lunar exosphere. It is important to note that the work described here is not to duplicate or exclude other lofting mechanisms -- in reality, the lofting of dust is almost definitely a complex combination of processes -- but instead to provide essential constraints on the impact contribution. This study attempts to constrain the expected contributions from cratering to the lunar exosphere by assessing the ejecta "background" signal lofted above the surface and the effects of transient focused events (meteor showers) which can produce significant increases in ejecta. In particular, this work couples scaling of previous ejecta studies with Monte-Carlo and ballistics models and will present LADEE data analysis (particularly from the UVS and LDEX instruments) and interpretation in context of constraining the ejected mass distribution. These results are relevant to both our understanding of exospheric dust and for constraint of hazards for future human habitation.

Using this technique different minerals have been recognized on the surfaces of solar system bodies. One of the principal products of extrusive volcanism and impact cratering is a glassy component, that can be abundant and thus significantly influence the spectral signature of the region investigated. Different types of glasses have been proposed and identified on the lunar surface and in star forming regions near young stellar objects. Here we report an initial effort of retrieving the optical constants of volcanic glasses formed in oxidizing terrestrial-like conditions. We also investigated how those calculations are affected by the grain size distribution. Bidirectional reflectance spectra, obtained with incidence and emission angles of 30 degrees and 0 degrees , respectively, were measured on powders of different grain sizes for four different glassy compositions in the VNIR. Hapke's model of the interaction of light with particulate surfaces was used to determine the imaginary index, k, at each wavelength by iteratively minimizing the difference between measured and calculated reflectance The basic approach to retrieving the optical constants was to use multiple grain sizes of the same sample and assume all grain sizes are compositionally equivalent. Unless independently known as a function of wavelength, an additional assumption must be made regarding the real index of refraction, n. The median size for each particle size separate was adopted for initially estimating k. Then, iterating the Hapke analysis results with a subtractive Kramers-Kronig analysis we were able to determine the wavelength dependence of n. For each composition we used the k-values estimated for all the grain sizes to calculate a mean k-value representing that composition. These values were then used to fit the original spectra by only varying the grain sizes. As a separate estimate of the k-values, we will use transmission measurements in the VNIR. Two slabs, with different thicknesses, will be measured for each composition. These data will be used to determine a k value and a comparison between k values obtained from the two different techniques will be discussed.

They represent a unique analog for Martian surface development conditions. Chemistry and mineralogy of soils and sediments from Taylor and Wright Valleys were analyzed. Samples from selected lakes, ponds and nearby surface areas were collected in 1979/1980, from sediments below Lake Hoare in 1994/95, and from lake surfaces in 2005/06. Surface samples are from Lakes Brownworth, Vanda and Fryxell; sediment cores from Lake Hoare, Don Juan and Don Quixote ponds. Systematic analysis by INAA, XRD, VNIR and mid-infrared spectroscopy, and other methods is underway for all samples. Classical major element weathering / pedogenesis ratiosand major element weathering indices are applied to ADV as well as MER and MSL rocks and soils. The Chemical Index of Alteration (CIA) values were used to characterize weathering conditions in Antarctic soils of Barton Peninsula and for sediment layers in Antarctic drill cores. The CIAs of sediment layers in drill cores are largely explained by the CIAs of source materials and reflect little or isochemical weathering. At Barton Peninsula with a less arid environment than the ADVs, CIAs of soils generally exceed those of source rocks. In Figure 1, two of several ADV soil source rocks and three sets of ADV soil and sediment CIAs are compared to molar Al2O3/TiO2 ratios. ADV CIA data are clustered and, as expected, lower than those of Barton Penisula, indicating a lesser degree of weathering. Very low ADV soil CIAs indicate sulfur rich samples. Full geochemical analysis as proposed will provide good indicators of weathering where historical to contemporary alteration conditions are liquid water based. Investigating elemental relationships for analogs that can be applied to Mars elemental abundance data bases is therefore important to assist in evaluating the extent of water based alteration derived from indicators in the Martian surface.

With NASA's goals for Mars now focused on determining the habitability of environments and detecting signs of past life, this mission constitutes a logical next step in the exploration of Mars. The Mars 2020 Science Definition Team's (SDT) suggested science objectives of the mission are to: 1) explore an astrobiologically relevant ancient environment on Mars to decipher its geological processes and history, including the assessment of past habitability; 2) assess the biosignature preservation potential within the selected geological environment and search for potential biosignatures; 3) demonstrate significant technical progress towards the future return of scientifically selected, well-documented samples to Earth; and 4) provide an opportunity for contributed human exploration or space technology Program participation, compatible with the science payload and within the mission's payload capacity. Instruments designed for detecting signs of past life and caching samples on Mars are among those considered by the Science Definition Team as the highest priority for science on the 2020 rover. This presentation will detail NASA's response to the SDT's report (released July 2013) in formulating the 2020 mission.

However the Giant Impact hypothesis currently explains the most details concerning the mean density, isotopic variations, and high system angular momentum. Other studies have been performed that constrain various conditions of the impact. However, few have probed the initial orbital state of the impactor. E. J. Rivera [PhD Thesis Stony Brook Univ. 2002] began an investigation assuming, initially, a 5 inner planet Solar System where 2 planets experienced an encounter to produce the Earth-Moon system. We extend this investigation to include updated numerical techniques and a more general parameter space. An initial configuration of giant planets akin to the current Solar System is used to explore where the Earth-Moon progenitors likely originated. Future extensions of this work will also be discussed, including the consideration of a debris rich environment and alternate initial configurations of the giant planets commensurate with the Nice model.

Laboratory measurements indicate that for pure water ice the position of the 3.6 mu m peak is temperature-dependent: it shifts towards shorter wavelengths when the ice is cooled, moving from about 3.65 mu m at T=123 K to about 3.55 mu m at T=88 K. Starting from this experimental evidence we have used a 4th-degree polynomial fit between 3.2 and 3.8 mu m to measure the wavelength at which the peak occurs with the view toward using it as a marker to retrieve the temperatures of the satellites. This method is applied to about 240 disk-integrated observations of Saturn's regular satellites collected by VIMS between 2004 and 2011 with solar phase in the 20-40 degrees range, corresponding to late morning-early afternoon local times. From these observations we have retrieved average temperatures for Mimas ( approximately 88 K), Enceladus (170 K). For some satellites, like Tethys and Dione, for which observations on both leading and trailing hemispheres are available, we have measured average temperatures higher by about 10 K on the trailing than on the leading hemisphere. Temperatures measured by VIMS with this method are in general much higher than corresponding ones reported by CIRS: this is a consequence of the shallow skindepth (few microns) to which VIMS is sensitive while CIRS measures temperature at greater depth (few millimeters). Grain size and contaminants embedded in water ice may also play a role in the 3.6 mu m peak properties and these effects have yet to be investigated. Combining VIMS and CIRS measurements will allow us to better characterize the regolith physical properties and heat transport mechanisms.

However, all surfaces show an absorption due to a non-water-ice component whose identity has not been well understood. In the near infrared, water ice has strong absorptions which limit detectability of other trace components. Similarly, at wavelengths less than about 0.18 microns, water is very absorbing. However, in the approximately 0.2 to approximately 1 micron range, water ice has low absorption and trace components are readily detected. Classical interpretations of the UV absorber and dark material on outer Solar System satellites have been varying amounts of tholins and carbon. However, tholins have spectral structure not seen in the icy spectra in the Saturn System. Many silicates also have UV spectral structure that reject them from contributing significantly to the observed spectral signatures. We have constructed a new UV spectrometer and a new environment chamber for studying the spectral properties of materials from 0.1 to 15 microns. In our survey of the spectral properties of materials so far, we find that small amounts of metallic iron and iron oxides in the icy surfaces are compatible with and can explain the UV, visible and near-infrared spectra of icy surfaces in the Saturn system (0.12 to 5.1 microns) using data from the Cassini UltraViolet Imaging Spectrograph (UVIS) and the Visual and Infrared Mapping Spectrometer (VIMS). The wide range of observed UV-NIR (0.1-5 micron) spectral signatures provide strong constraints on composition and grain size distribution, including grain sizes of the ice. Spectra of the Saturnian rings and icy satellites indicate they have a large range of ice grain sizes, from tens of microns to sub-micron. Sub-micron ice grains create unusual spectral properties, which are seen in the spectra of the rings and satellites of Saturn and on satellites further out in the Solar System. Clark et al. (2012, Icarus v218, p831) showed that VIMS spectra were explained by combinations of water ice, CO2, nano-sized grains of metallic iron and iron oxide and trace amounts of other compounds. The new UV lab data are providing further evidence for this interpretation and placing further constraints on grain size distributions and abundances of the components.

To fulfill these goals, LEND has been mapping the distribution of thermal and epithermal neutron leakage flux since LRO entered its mapping orbit in September 2009. LRO moved to an elliptical orbit in December 2011, with 30 km periselene over the south pole and aposelene above the north pole. During the commissioning phase of the mission, July-September 2009, LEND obtained preliminary mapping of hydrogen/water deposits near the south pole that contributed to site-selection for the LCROSS impact. Global maps of neutron leakage flux measured with LEND show regional variation in thermal (energy 0.5 MeV) neutrons, and map epithermal neutron flux globally. Spatial resolution of the collimated detector is consistent with the design value of 5 km radius for half the detected lunar epithermal neutrons, with the remainder spatially diffuse. Statistically significant neutron-suppressed regions (NSRs) are not closely related to polar PSRs. Outside of the NSRs, hydrogen content increases directly with latitude at both poles. Thermal volatilization of water deposits may be responsible for increasing H concentrations nearer the poles because it is minimized at the low surface temperature of the poles. Significant neutron suppression regions (NSRs) relative to neighboring regions have been found in three large PSRs, Shoemaker and Cabeus in the south and Rozhdestvensky U in the north. Some small PSRs display excess neutron emission compared to the sunlit vicinity. On average, PSRs other than these three do not contain significantly more hydrogen than sunlit areas around them at the same latitude. Correlation between neutron suppression measured by LEND and illumination models for the Moon's polar regions suggests that insolation at the poles is an important factor in locally modulating hydrogen concentrations so that the highest concentrations of hydrogen appear to be on poleward-facing vs. equator-facing slopes. Epithermal neutron flux is slightly suppressed near the dawn terminator at near-equatorial latitude, with least suppression in local lunar mid-afternoon, implying a mobile population of hydrogen-bearing volatiles near the terminator that resides transiently in the regolith. The observed pattern supports hypothesized mineral hydration at the terminator in the form of H2O/OH.

In this investigation, UCIS was used in a micro-imaging configuration in a laboratory environment to image the reflectance spectra of solid rock samples in the visible through shortwave-infrared wavelengths (0.50 to 2.50 mu m.) These data were used both to evaluate the capabilities of UCIS at the micro-scale and to analyze the spectral and mineralogical diversity of rocks from Mars-analog sites. The primary site of interest for this investigation was the Samail Ophiolite in Oman, where subsurface serpentinization and subsurface/subaerial carbonate deposition mimic some of the processes undergone by a Noachian Mars. Data were processed with the IDL-based image analysis software ENVI to generate detailed parameter maps distinguishing carbonate and serpentine minerals in varying modes of aqueous alteration. Close inspection of these maps yielded new spectral parameters, including the strength of absorption bands at 1.39, 1.90, 2.12, and 2.34 mu m, continuum shapes including slopes about 1.08 mu m, and feature shifting, which reliably identify and map serpentines and carbonates with distinct cation contents, water contents, and internal textures. These spectral parameters were combined to produce detailed color composite maps which informed our understanding of the relationships between phases and the extent of aqueous alteration in the Oman samples. Areal maps of mineral phases were used to quantitatively estimate the mineralogy of samples nondestructively, comparing to standard techniques such as x-ray diffraction and electron microprobe analysis, which require processing or destruction of rock samples. Our maps and measurements will provide a means for comparison between these techniques and the imaging spectroscopy performed by UCIS at the micro-scale.

From the large amount of spectra retrieved we have derived spectral parameters which can be combined to identify specific physical and compositional states. To start with, we have computed the band center and depth for band I and band II of pyroxenes. Pyroxene's band center I and II are commonly associated with a compositional variation. For example, orthopyroxene bands shift towards longer wavelengths with increasing amounts of iron, while clinopyroxene bands shift towards longer wavelengths with increasing calcium content. Band depths are related to scattering effects, associated to the abundance and the grain size of the absorber. Mapping these parameters on the surface allow to detect terrain units compositions and physical-state in their stratigraphic context. We have produced an atlas of digital maps, projected following the 15-quadrangle scheme commonly adopted for small sized planetary bodies. The digital maps have geospatial metadata and are available in GIS and other scientific programming language formats. A special imagery product has been produced, where the geomorphologic context from the Framing Camera, and the IAU nomenclature have been added to the mineralogic maps. This way we have both quantitative digital maps and print-ready maps. Digital maps are useful in statistical and geo-processing studies, while print-ready maps represent an easy to be consulted high-level data products. As with the atlas we are combining data acquired at very different observing geometries and in different phases of the mission, filtering has been necessary and an iterative process to project data produces results that are incrementally more consistent as we detect and exclude source of artifacts. At the moment of writing, the atlas has reached version 2.0, and most likely it will be updated by fall with an improved version. Moreover, the current number of 56 maps will increase as soon as new parameters, or a combination of them, will be added to the atlas.

These interactions produce alteration features on the surfaces of rocks, which record information about the amount and types of fluids with which the rock has interacted. Alteration features can also be indicators of and habitats for microbial life in terrestrial environments. Thus, detecting rock surface alteration is an important part of the NASA Curiosity rover mission to Gale crater, Mars. The ChemCam LIBS instrument onboard Curiosity is uniquely suited to detecting and analyzing rock surface alteration. The LIBS technique uses a pulsed laser microbeam (350-550 mu m) to ablate small amounts of material from a target to form a plasma. Because some material is removed during each laser pulse, it is possible to obtain a depth profile of chemical composition by performing multiple laser pulses on one location. Each pulse returns a spectrum that represents the composition at a specific depth, with each subsequent shot sampling the composition at a slightly greater depth. Laboratory measurements of basalts have shown that each LIBS shot removes at least approximately 0.3-0.82 mu m/shot, suggesting a removal of approximately 9-25 mu m of the surface for a standard analysis of 30 shots in rocks of similar hardness. Here we present laboratory LIBS experiments on well-characterized terrestrial rock samples with coatings and rinds with the goal of understanding the signatures of such features in LIBS data from Mars. The terrestrial sample set includes a basalt with a approximately 0-50 mu m thick Mn-rich rock varnish and a thin (<1 mm) weathering rind and a sandy dolomite with a approximately 500 mu m thick Ca-rich rind. Both samples were interrogated with hundreds of LIBS shots per location three times on the unweathered interior and three times on the exterior. Results from the basalt show that compositions similar to the bulk rock composition was reached by approximately 50-70 shots, with the observed chemical changes suggesting both the varnish and at least some rind were penetrated. Results from the sandy dolomite do not show as clear a change from rock exterior to interior as the basalt, but a general chemical trend from exterior to interior was observed in all three depth profiles. Laboratory results suggest that depth profiles of at least 100 shots are useful for clearly identifying coatings and rinds of similar thickness to those found on Earth. However, alteration trends may still be discernible with fewer shots. On Mars, the rock Bathurst Inlet (sol 55), which was shot only 30 times per location, shows what appears to be a near-surface gradient of several elements, most notably Li. Trends similar in nature (if not composition) to the terrestrial sandy dolomite sample were also observed on raised ridge materials such as McGrath (sub 5) (sol 234). Additional martian samples also show trends similar to coatings and rinds measured in the laboratory, suggesting that there may be surface alteration of some rocks in Gale crater.

The Mars Organic Molecule Analyzer (MOMA) aboard the ExoMars rover will be a key analytical tool in providing chemical (molecular) information from the solid samples, with particular focus on the characterization of organic content. Central to MOMA instrumentation is a gas chromatograph-mass spectrometer (GC-MS) which provides the unique ability to characterize a broad range of compounds allowing chemical analyses of volatile and non-volatile species. The Gas chromatograph and the oven have been built at LATMOS/LISA (France) and at MPS (Germany) respectively whereas the mass spectrometer has been built at the NASA Goddard Space Flight Center (USA). Both instruments have been tested separately first and have been coupled in order to test the efficiency of the future MOMA GC-MS instrument. The main objective of the second step has been to test the quantitative response of both instruments while they are coupled and to characterize the combined instrument detection limit for several compounds. A final experiment has been done in order to test the feasibility of the separation and detection of a mixture contained in a soil sample introduced in the MOMA oven.

Although the instrument is beginning to show the effects of tens of thousands of thermal cycles and the natural process of the aging of the laser transmitters, LOLA continues to acquire data on the sunlit portion of every orbit on all 5 laser beams when below 100-km altitude. LOLA has acquired over 6X10 (super 9) altimeter measurements, all geodetically controlled to the center-of-mass of the Moon with a radial precision of around 10 cm and an accuracy of about 1 meter. The position of the measurements on the lunar surface is primarily limited by the knowledge of the position of the spacecraft in orbit; in the last year the LRO orbit accuracy has improved significantly as a result of the availability of an accurate gravity model of the Moon from the GRAIL Discovery mission. Our present estimate of positional accuracy is less than 10 m rms but is only achievable with a GRAIL gravity model to at least degree and order 600 because of the perturbing gravitational effect of the Moon's surface features. Significant improvements in the global shape and topography have assisted the Lunar Reconnaissance Orbiter Camera (LROC) stereo mapping program, and the identification of potential lunar landing sites for ESA and Russia, particularly in the high-latitude polar regions where 5- and 10-meter average horizontal resolution has been obtained. LOLA's detailed mapping of the polar regions has improved the delineation of permanently-shadowed areas and assisted in the understanding of the LEND neutron data and its relationship to surface slopes. Recently, a global, calibrated LOLA normal albedo dataset at 1064 nm has been developed and is being combined with analysis and modeling by the Diviner team for the identification of the coldest locations in the polar regions.

This material forms low-radar-return and low-radar-CPR haloes external to radar-bright blocky crater ejecta. The haloes' radar signature persists at multiple radar wavelengths and is consistent with depletion in wavelength-scale scatterers (e.g., rocks) on the surface and up to several meters' depth. The exact formation mechanism remains unknown, but successful hypotheses must be able to explain the inferred paucity of rocks. Here, we investigate these features further using new data from the LRO Diviner thermal mapper. Diviner data provide a means of characterizing the thermophysical properties of the surface and near-surface regolith column, to a depth of approximately 1 meter. Specific to radar-dark, block-poor ejecta haloes, we use two Diviner-derived quantities: rock abundance values, which yield estimates of the number of surface blocks 1 meter and larger; and rock-free regolith temperature, which provide information about the density of the regolith column in the absence of exposed rocks (and which are sensitive to the presence of small surface and/or larger buried rocks). Using these two quantities gridded at a spatial scale of 128 pixels/degree ( approximately 250 m at the equator), we observe that craters with radar-dark haloes in the nearside maria show corresponding signatures of depletion in both large and small/buried rocks. In this work, we investigate further quantitative constraints on the thickness and character of these deposits that may be derived from thermal modeling of the regolith column.

NASA and ESA are currently planning a series of robotic missions to Mars with the goal of understanding its climate, resources, and potential for harboring past or present life. One key goal will be the search for chemical biomarkers including organic compounds important in life on Earth and their geological forms. These compounds include amino acids, the monomer building blocks of proteins and enzymes, nucleobases and sugars which form the backbone of DNA and RNA, and lipids, the structural components of cell membranes. Many of these organic compounds can also be formed abiotically as demonstrated by their prevalence in carbonaceous meteorites, though, their molecular characteristics may distinguish a biological source. It is possible that in situ instruments may reveal such characteristics, however, return of the right samples to Earth (i.e. samples containing chemical biosignatures or having a high probability of biosignature preservation) would enable more intensive laboratory studies using a broad array of powerful instrumentation for bulk characterization, molecular detection, isotopic and enantiomeric compositions, and spatially resolved chemistry that may be required for confirmation of extant or extinct life on Mars or elsewhere. In this presentation we will review the current in situ analytical capabilities and strategies for the detection of organics on the Mars Science Laboratory (MSL) rover using the Sample Analysis at Mars (SAM) instrument suite and discuss how both future advanced in situ instrumentation and laboratory measurements of samples returned from Mars and other targets of astrobiological interest including the icy moons of Jupiter and Saturn will help advance our understanding of chemical biosignatures in the Solar System.

We seek to provide an comprehensive framework for the study of the increasingly rich observational data sets (including stellar occultations of the atmosphere) and to provide context and analysis of observations from the New Horizons mission. The PlutoWRF GCM is based on the planetary adaptation of the NCAR Weather Research and Forecasting (WRF) model. It is a compressible, nonhydrostatic model where we have added physics to treat radiative transfer following Zhu et al. (2013), a bulk nitrogen cycle including condensation of surface ice, and cycles of additional trace volatile species. Existing subsurface heat diffusion, surface layer exchange and boundary layer mixing schemes have been adapted to Pluto. Boundary conditions for initial ice distribution and surface pressure are taken from energy balance and non-GCM volatile transport models constrained by observations. In this work we focus on the performance of the PlutoWRF GCM compared with our linear tidal model (Toigo et al., 2010), and will examine the generation and propagation of large-scale gravity waves associated with diurnal sublimation and condensation.

Student powered video rap 'battle' over tiny Pluto's embattled planetary standing AN - 1700095601; 2015-072573 AB - Is Pluto a planet? Some creative low income Bay-area middle-schoolers put a musical spin on this hot science debate with a video rap 'battle' over tiny Pluto's embattled planetary standing. The students' timing was perfect, with NASA's New Horizons mission set to conduct the first reconnaissance of Pluto and its moons in July 2015. Pluto--the last of the nine original planets to be explored by spacecraft--has been the subject of scientific study and speculation since Clyde Tombaugh discovered it in 1930, orbiting the Sun far beyond Neptune. Produced by the students and a very creative educator, the video features students "battling" back and forth over the idea of Pluto being a planet. The group collaborated with actual space scientists to gather information and shot their video before a "green screen" that was eventually filled with animations and visuals supplied by the New Horizons mission team. The video debuted at the Pluto Science Conference in Maryland in July 2013--to a rousing response from researchers in attendance. The video marks a nontraditional approach to the ongoing "great planet debate" while educating viewers on a recently discovered region of the solar system. By the 1990s, researchers had learned that Pluto possessed multiple exotic ices on its surface, a complex atmosphere and seasonal cycles, and a large moon (Charon) that likely resulted from a giant impact on Pluto itself. It also became clear that Pluto was no misfit among the planets--as had long been thought--but the largest and brightest body in a newly discovered "third zone" of our planetary system called the Kuiper Belt. More recent observations have revealed that Pluto has a rich system of satellites--five known moons--and a surface that changes over time. Scientists even speculate that Pluto may possess an internal ocean. For these and other reasons, the 2003 Planetary Decadal Survey ranked a Pluto/Kuiper Belt mission as the highest priority mission for NASA's newly created New Frontiers program and that mission is New Horizons. This effort was funded by a Hewlett Packard Sustainability and Social Innovation grant, the Silicon Valley Education Foundation and a Kickstarter campaign to expand this effort to multiple schools. This process and product are great examples of teamwork between scientists and science educators--and show how we can use the appeal of video to communicate science to diverse audiences.

Last visited by Voyager 2 in 1989, Neptune and its moon Triton hold important clues to the evolution of the solar system. The Voyager 2 flyby revealed Neptune to be a dynamic world with large storms, unparalleled wind speeds, and an unusual magnetic field. Triton, Neptune's largest satellite, is believed to be a captured Kuiper Belt Object with a thin atmosphere and possible sub-surface ocean. Further study of the farthest planet in our solar system could offer new insights into the dynamics of ice-giant exoplanets, and help us understand their complex atmospheres. The diverse science questions associated with Neptune and Triton motivate the complex and exciting mission proposed in this study. The proposed mission follows the guidelines of the 2013-2022 Planetary Science Decadal Survey, and optimizes the number of high priority science goals achieved, while still maintaining low mission costs. High priority science goals include understanding the structure, composition, and dynamics of Neptune's atmosphere and magnetosphere, as well as analyzing the surface of Triton. With a budget of $1.5 billion, the mission hosts an atmospheric probe and suite of instruments equipped with technologies significantly more advanced than those carried by Voyager 2. Additionally, the mission offers improved spatial coverage and higher resolution measurements than any previously achieved at Neptune. The proposed spacecraft would complete an orbital tour of Neptune and execute several close flybys of Triton. Further study of Neptune and Triton will provide exciting insights into what lies on the edge of our solar system and beyond. This study was prepared in conjunction with Jet Propulsion Laboratory's 2013 Planetary Science Summer School.

Within the mats, oxygenic photosynthesis provides organic substrates and O2 to the community. Both the absorption and scattering of light change the intensity and spectral composition of incident radiation as it penetrates a mat. Some phototrophs utilize infrared light near the base of the photic zone. A mat's upper layers can become highly reduced and sulfidic at night. Counteracting gradients of O2 and sulfide shape the chemical environment and provide daily-contrasting microenvironments separated on a scale of a few mm. Radiation hazards (UV, etc.), O2 and sulfide toxicity elicit motility and other physiological responses. This combination of benefits and hazards of light, O2 and sulfide promotes the allocation of various essential mat processes between light and dark periods and to various depths in the mat. Associated nonphotosynthetic communities, including anaerobes, strongly influence many of the ecosystem's overall characteristics, and their processes affect any biosignatures that enter the fossil record. A biosignature is an object, substance and/or pattern whose origin specifically requires a biological agent. The value of a biosignature depends not only on the probability of life creating it, but also on the improbability of nonbiological processes producing it. Microbial mats create biosignatures that identify particular groups of organisms and also reveal attributes of the mat ecosystem. For example, branched hydrocarbons and pigments can be diagnostic of cyanobacteria and other phototrophic bacteria, and isoprenoids can indicate particular groups of archea. Assemblages of lipid biosignatures change with depth due to changes in microbial populations and diagenetic transformations of organic matter. The 13C/12C values of organic matter and carbonates reflect isotopic discrimination by particular microorganisms as well as networks of C flow within mats; thus they offer insights about community structure. For example, relative 13C/12C values of individual lipid biosignatures can indicate trophic relationships between key groups of microorganisms. Mat microenvironments can affect the stability of authigenic minerals and alter the chemical compositions and crystal forms of carbonate, sulfate and metal oxide minerals. Interactions between low molecular weight organic compounds and sulfides in mat pore waters can produce alkyl sulfide gases. Processes associated with these physically coherent biofilms can trap and bind detrital grains, enhance mineral precipitation or dissolution, and stabilize sediment surfaces. Accordingly mats can create distinctive sedimentary fabrics and structures. Stromatolites are the most ancient, widespread examples of such fabrics and structures. Thus photosynthetic microbial mats create diverse biosignatures that, when preserved in the geologic record, can help to identify the former presence of key populations of microorganisms and reveal key processes that occurred within ancient mats as well as the interactions between those ecosystems and their environment.

These components may be used to electrically isolate geological samples from the experimental equipment, to perform a mechanical compliance function between brittle samples and the loading equipment, to match ultrasonic transducers, or perform other functions. In many experimental configurations the insulators bear the full brunt of force applied to the sample but do not need to withstand high voltages, therefore the insulators are often thin sheets of mechanically tough polymers. From an instrument perspective, transduction from various types of mechanical perturbation has been qualitatively compared for a number of polymers [1, 2] and these error sources are readily apparent during high-impedance measurements if not mitigated. However even when following best practices, a force-dependent voltage signal still remains and its behavior is explored in this presentation. In this experiment two thin sheets (0.25 mm) of high-density polyethylene (HDPE) were set up in a stack, held alternately between three aluminum bars; this stack was placed on the platen of a 60T capacity hydraulic testing machine. The surface area, A, over which the force is applied to the PE sheets in this sandwich is roughly 40 square cm, each sheet forming a parallel-plate capacitor having roughly 320 pF [3], assuming the relative dielectric permittivity of PE is approximately 2.3. The outer two aluminum bars were connected to the LO input of the electrometer and the central aluminum bar was connected to the HI input of a Keithley model 617 electrometer. Once the stack is mechanically well-seated with no air gaps, the voltage offset is observed to be a linear function of the baseline voltage for a given change in applied force. For a periodically applied force of 66.7 kN the voltage offsets were measured as a function of initial voltage, and these data were fit with a linear function that was constrained to pass through the origin. The best fit solution had a correlation coefficient of R = 0.85 and a slope of approximately -0.0228 volts/volt. The voltage offset when normalized is demonstrated to be constant -2.28 % for both positive and negative polarities over nearly 3 orders of baseline voltage magnitude. From this, the voltage-force coefficient is derived to be -0.34 ppm/N. This correlates well to a first-order parallel plate capacitor model that assumes constant area, and small deformation such that the polymer may be mechanically modeled by a spring that obeys Hooke's law. This simple model predicts that the coefficient of proportionality is a function of Young's modulus E = 0.8 GPa and surface area of the insulator, theoretically -1/EA = -0.31 ppm/N. The outcome of this work is an improved insulator made from ultra-high molecular weight (UHMW) polyethylene and other approaches toward the minimization of and compensation for these experimental artifacts.

Some studies claim there are global effects, relating solar activity, for instance sunspot number or solar wind speed, with earthquakes occurrence on the Earth. Other studies intend to find effects on a local scale, where perturbations in the geomagnetic activity are followed by seismic events. To address these issues, we analyze the statistical validity of some of the reported correlations, by means of two statistical approaches in both scales, namely the use of surrogate and Student's test. Regarding to the global analysis, we study the correlations between the sunspots area, Dst index, and the total annual released seismic energy during the last century. For local geomagnetic variations prior to an important earthquake, we carry out a similar statistical analysis between magnetic field fluctuations from the SAMBA array and the Dst index in a window of two years centered in the February 27th, 2010 M = 8.8 earthquake at Chile.

AN - 1696876829; 2015-068364 AB - The potential difference between Earth's surface and the lower edge of the ionosphere is estimated to be on the order of 250 kV, highly variable with values quoted as high as 500 kV. The polarity is uncertain. According to the prevailing view in the Global Electric Circuit community, the Earth's surface is negative relative to the lower edge of the ionosphere, which is believed to be positive. The polarity of the global E field is based on the following reasoning: (i) worldwide lightning strikes, about 6 per sec, constantly deliver electrons to the solid Earth, thereby charging the ground negative; (ii) positive ions have been observed to drift upward above thunderstorm systems, thereby charging the lower edge of the ionosphere positive. This polarity cannot be correct. The sign of Earth's ground is definitely positive. Here is why: Essentially all crustal rocks contain peroxy defects, which release positive hole charge carriers as the rocks are subjected to tectonic stresses. The positive hole charge carriers dominate the electrical conductivity throughout the upper to middle crust. Being highly mobile, they spread to the Earth surface, building up a positive surface charge. Precisely because the ground is positive are lightning strikes attracted to the ground. The Earth ground rapidly dissipates the electrons delivered by lightning strikes in the same way as "the ground" dissipates electric currents from technical installations. Otherwise our electric grid would not function. Hence, the lower edge on the ionosphere must be negative. This is evidenced by the widely reported increase in TEC, "Total Electron Content", over regions of impending earthquake activity. The reason is that, due to field-ionization of air molecules at the (positive) ground-to-air interface, the air becomes heavily laden with positive airborne ions. These ions rise to stratospheric height and upward through the mesosphere. The ionospheric plasma becomes polarized: its electrons move downward in response to the positive ions moving upward. In the steady state, the Global Electric Circuit the number of negative charges (electrons) delivered downward must be approximately equal to the number of positive charges (ions) delivered upward. Any imbalance between the two partial fluxes will lead to a potential difference, which - presumably - is the highly variable approximately 250 kV potential difference quoted to exist between the ground and the lower edge of the ionosphere.

This project was initially motivated by a desire to understand the transfer of heat from a lava flow into the lunar regolith. Ancient regolith deposits that have been protected by a lava flow may contain ancient solar wind, solar flare, and galactic cosmic ray products that can give insight into the history of our solar system, provided the records were not heated and destroyed by the overlying lava flow. In addition, lava-substrate interaction is an important aspect of lava fluid dynamics that requires consideration in lava emplacement models Our numerical model determines the depth to which the heat pulse will penetrate beneath a lava flow into the underlying substrate. Rigorous treatment of the temperature dependence of lava and substrate thermal conductivity and specific heat capacity, density, and latent heat release are imperative to an accurate model. Experiments were conducted to verify the numerical model. Experimental containers with interior dimensions of 20 x 20 x 25 cm were constructed from 1 inch thick calcium silicate sheeting. For initial experiments, boxes were packed with lunar regolith simulant (GSC-1) to a depth of 15 cm with thermocouples embedded at regular intervals. Basalt collected at Kilauea Volcano, HI, was melted in a gas forge and poured directly onto the simulant. Initial lava temperatures ranged from nearly equal 1200 to 1300 degrees C. The system was allowed to cool while internal temperatures were monitored by a thermocouple array and external temperatures were monitored by a Forward Looking Infrared (FLIR) video camera. Numerical simulations of the experiments elucidate the details of lava latent heat release and constrain the temperature-dependence of the thermal conductivity of the particulate substrate. The temperature-dependence of thermal conductivity of particulate material is not well known, especially at high temperatures. It is important to have this property well constrained as substrate thermal conductivity is the greatest influence on the rate of lava-substrate heat transfer. At Kilauea and Mauna Loa Volcanoes, Hawaii, and other volcanoes that threaten communities, lava may erupt over a variety of substrate materials including cool lava flows, volcanic tephra, soils, sand, and concrete. The composition, moisture, organic content, porosity, and grain size of the substrate dictate the thermophysical properties, thus affecting the transfer of heat from the lava flow into the substrate and flow mobility. Particulate substrate materials act as insulators, subduing the rate of heat transfer from the flow core. Therefore, lava that flows over a particulate substrate will maintain higher core temperatures over a longer period, enhancing flow mobility and increasing the duration and aerial coverage of the resulting flow. Lava flow prediction models should include substrate specification with temperature dependent material property definitions for an accurate understanding of flow hazards.

The Jemez lineament is a result of rifting in the Earth's crust and is associated with volcanic activity that spans the last 16 Ma. The youngest volcanic activity associated with the lineament includes basaltic lava that was erupted 3 ka ago to form the McCartys Flow. The Twin Craters flow is moderately older (18.0 ka), but it also well-preserved and provides an ideal location to investigate volcanic processes and landforms. In this study, we combined detailed field observations and mapping with remote sensing to better understand variations in morphology along the transport system of the flow . The Twin Craters flow is characterized as an aa and tube-fed pahoehoe flow with braided or branching tubes and channels; and associated aa and pahoehoe break-outs. It is possible that the variations in morphology along the same transport structure might be related to pre-flow slope, which might have also been variable along flow. Shatter ring features are thought to be related to changes in eruption rate, and therefore, local flux through the system. However, over-pressurization of the tube might also be related to changes in local discharge rate associated with the ponding and release of lava within the transport system that may be due to interactions between the lava and obstacles along the flow's path (see Mallonee et al., this meeting). Many of these features are similar to features present in the Tharsis Montes region of Mars and particularly on the southern apron of Ascraeus Mons. The detailed description of the morphology of the Twin Craters Lava Flow and the understanding of the emplacement mechanisms will be crucial in identifying the processes that formed the Ascraeus flows and channels. This will aid in determining if the lava surface textures are directly related to eruption conditions or if they have been significantly influence by transport processes.

Remotely sensed data combined with physically-based models of landslide initiation are a potentially economical solution for anticipating landslide activity over large, national or multinational areas as a basis for landslide early warning. Detailed high-resolution landslide modeling is challenging due to difficulties in quantifying the complex interaction between rainfall infiltration, surface materials and the typically coarse resolution of available remotely sensed data. These slope-stability models calculate coincident changes in driving and resisting forces at the hillslope level for anticipating landslides. This research seeks to better quantify the uncertainty of these models as well as evaluate their potential for application over large areas through detailed sensitivity analyses. Sensitivity to various factors including model input parameters, boundary and initial conditions, rainfall inputs, and spatial resolution of model inputs is assessed using a probabilistic ensemble setup. We use the physically-based USGS model, TRIGRS (Transient Rainfall Infiltration and Grid-Based Regional Slope-Stability), that has been ported to NASA's high performance Land Information System (LIS) to take advantage of its multiple remote sensing data streams and tools. We apply the TRIGRS model over an example region with available in-situ gage and remotely sensed rainfall (e.g., TRMM: http://pmm.nasa.gov). To make this model applicable even in regions without relevant fine-resolution data, soil depth is estimated using topographic information, and initial water table depth using spatially disaggregated coarse-resolution modeled soil moisture data. The analyses are done across a range of fine spatial resolutions to determine the corresponding trend in the contribution of different factors to the model output uncertainty. This research acts as a guide towards application of such a detailed slope-stability model over coarser resolutions and larger areas.

Yet, heat flow in the martian crust was higher in the Noachian and therefore the planet was likely more magmatically active [1]. It is possible that Noachian volcanic constructs have largely escaped detection because higher erosion rates on ancient Mars destroyed geomorphological evidence for their existence. However, another possibility exists: some ancient volcanoes on Mars might have been of a fundamentally different character compared to well known, younger shield volcanoes because of an explosive nature of the more ancient ones. We present evidence for ancient supervolcanoes within the Arabia Terra region of Mars. Several large ( nearly equal 20-70 km-diameter) craters within Arabia Terra display little or no evidence for impact origins and exhibit various degrees of evidence for volcanism. These structures, which we term "plains style caldera complexes," show no evidence for preserved ejecta, raised rims, inverted stratigraphy, or central peaks that could be attributed to meteor impact-related processes. While it is possible that any evidence for impact origins was removed by erosion, we consider this unlikely because crater degradation generally leads to lower depth-diameter ratios [2] and these structures have high depth-diameter ratios, comparable to values for unmodified craters [3]. In fact, erosion has been low enough to preserve various pieces of evidence for volcanism associated with the structures, such as association with ridged plains lavas, possible vent structures, evidence for lava lakes in some cases, and association with sagging crust possibly related to magma migration or withdrawal. Taken together, these structures represent a newly recognized type of volcanism on Mars dominated by explosive volcanism and structural collapse. They occur within a region of Mars not previously thought to contain volcanoes, but known to have anomalously thin crust [4]. We suggest that the explosive volcanism need not require the presence of magmas of evolved composition or unusually high volatile content; basaltic magmas that ascended rapidly through relatively thin crust could have plausibly resulted in explosive volcanism. Eruption of vast quantities of fine-grained ash in northern Arabia Terra might have ultimately led to the formation of fretted terrain, composed of friable, layered, fine-grained deposits along the dichotomy boundary, as well as the deposition of friable layered deposits located throughout Arabia Terra.

Current estimates of blast damage (e.g., [1]) rely on uncertain impact energies for events like Sikhote-Alin (1947), Tunguska (1908), and Barringer Meteorite Crater ( approximately 50 ka). The Chelyabinsk air burst event of an LL-chondrite NEA on 15 February 2013 provides a calibration point for enhancing those assessments. U.S. Government sensors indicate the impacting NEA had a velocity of 18.6 km/s and kinetic energy approximately 440 kt [2] with a total energy of possibly 500 kt. Using average bulk densities of LL-chondrite falls (3.22 g/cm (super 3) ) and S-class main belt asteroids (2.7 g/cm (super 3) ) [3], we derive an average diameter of 18.6 and 20 m, respectively. If the density was similar to that of rubble-pile LL-chondritic NEA Itokawa (1.9 g/cm (super 3) [4]) or rubble-pile binary NEAs ( approximately 1.5 g/cm (super 3) ), then the diameter may have been as large as 22 to 24 m. The strength of impacting NEA may be limited to structural flaws, like fractures and material contrasts (e.g., [5]); indeed, fragmental meteoroids preferentially produce meteorite showers. Not surprisingly, Chelyabinsk is a brecciated LL-chondrite and cross-cut with impact melt veins that were generated by older collisional events. Impact-generated cataclasis produced a breccia of light-colored chondrule-bearing clasts with sub-millimeter-wide fractures and silicate-rich shock melt veins, some of which form melt pockets where they intersect. Those clasts are separated by thin, sub-millimeter-wide channels of dark-colored matrix and centimeter-wide swaths of vesiculated and heterogeneously quenched impact melt. Catastrophic fragmentation of these types of NEA can produce ground-level air blast effects if that fragmentation occurs at a sufficiently low altitude. Based on pre-Chelyabinsk scaling [1], blast damage over an area of 10 (super 2) to 10 (super 3) km (super 2) is expected for a 440-500 kt event. The 20-meter-diameter Chelyabinsk meteoroid was composed of LL-type material, similar to that re-covered from the 540-m-long Itokawa asteroid [6]. Both of those NEA were derived from one or more parent bodies >100 km diameter(s). Over 5,000 samples from an LL-chondrite parent body(ies) exist. Collisional events at 4.35-3.9 Ga are well-documented and several younger events have been suggested [7]. Whether one of those events or a separate event is responsible for the impact melt in Chelyabinsk is, as yet, unclear, but Ar-Ar analyses of the clasts and melt within Chelyabinsk are underway.

Most tsunami fatalities occur in near-field communities of earthquakes at offshore faults. Tsunami early warning is key for reducing the number of fatalities. Unfortunately, an earthquake's magnitude often does not gauge the resulting tsunami power. Here we show that real-time GPS stations along coastlines are able to detect seafloor motions due to big earthquakes, and that the detected seafloor displacements are able to determine tsunami energy and scales instantaneously for early warnings. Our method focuses on estimating tsunami energy directly from seafloor motions because a tsunami's potential or scale, no matter how it is defined, has to be proportional to the tsunami energy. Since seafloor motions are the only source of a tsunami, their estimation directly relates to the mechanism that generates tsunamis; therefore, it is a proper way of identifying earthquakes that are capable of triggering tsunamis, while being able to discriminate those particular earthquakes from false alarms. Examples of detecting the tsunami energy scales for the 2004 Sumatra M9.1 earthquake, the 2005 Nias M8.7 earthquake, the 2010 M8.8 Chilean earthquake, and the 2011 M9.0 Tohoku-Oki earthquake will be presented.

Some pre-earthquake (pre-EQ) processes affect the ionosphere, others leave their mark on biota. We report (i) on ionospheric anomalies recorded prior to the M=7 Contamana EQ [1] in North-Eastern Peru, 134 km deep, associated with the subduction of the Nazca plate underneath the Northern Andes, (ii) on changes in animal activity recorded in the Yanachaga National Park, about 320 km from the EQ epicentre, over a 30 day period leading up to the M=7 seismic event. Night-time Very Low Frequency (VLF) phase data were analyzed for the period 01 June to 31 Oct. 2011 using propagation paths passing close to the Yanachaga Park from the NAA emitter (USA) to receivers PIU in Piura and PLO in Lima (Peru). Ionospheric phase perturbations were observed starting 2 weeks before the EQ with periodicities from few tens of secs to few minutes. Animal activity data were obtained by evaluating the images of a cluster of 10 motion-triggered cameras of the Tropical Ecology Assessment and Monitoring Network www.teamnetwork.org. We analyzed 1359 photographic records for the pre-EQ period and 1491 photographic records for a control period with low seismicity. Animal activity started to noticeably decline 3 weeks before the EQ. Different animal species were found to react differently. The number of rodents declined to zero about one week before the EQ and so did the number of tapirs. Armadillos, a burrowing animal, were recorded in larger numbers. Though the armadillos were presumably also flushed out of their holes, they apparently did not hide like the rodents. We discuss the results in the context of recent advances in solid state physics, which provide plausible mechanisms for pre-EQ ionospheric anomalies and for changes in animal behavior.

Yet while hurricanes and earthquakes have global monitoring systems in place to alert disaster response agencies, governments and regional humanitarian groups of potential disasters and related impacts, no such real-time monitoring system exists for rainfall-triggered landslides. This research seeks to advance the use and application of remotely sensed data and build upon existing modeling efforts to create a robust landslide hazard assessment system with the goal of better informing decision-making and disaster response agencies on landslide hazards at the regional scale. This system outputs a straightforward, easily-interpreted set of landslide hazard assessment products available in near real-time for the Mesoamerica region that can be used to both identify landslide-prone areas and forecast the potential location and timing of landslide initiation in the future. This research presents the prototype regional model tested over seven countries in Central America using satellite-based information including Tropical Rainfall Measurement Mission (TRMM) near real-time rainfall, topography data, modeled soil moisture, and geologic information. These variables are integrated within a simple algorithm framework and model outputs provide a probabilistic representation of potential landslide activity over the region. This presentation summarizes the preliminary results of this modeling framework, discusses the utility of these products for landslide hazard characterization, and outlines the path forward for this modeling approach.

In the Earth Sciences, one such activity is collecting remotely sensed imagery of disaster areas and making those data immediately available through the USGS Hazards Data Distribution System, especially in response to activations of the International Charter for Space and Major Disasters (known informally as the "International Disaster Charter", or IDC). The ISS, together with other NASA orbital sensor assets, responds to IDC activations following notification by the USGS. Most of the activations are due to natural hazard events, including large floods, impacts of tropical systems, major fires, and volcanic eruptions and earthquakes. Through the ISS Program Science Office, we coordinate with ISS instrument teams for image acquisition using several imaging systems. As of 1 August 2013, we have successfully contributed imagery data in support of 14 Disaster Charter Activations, including regions in both Haiti and the east coast of the US impacted by Hurricane Sandy; flooding events in Russia, Mozambique, India, Germany and western Africa; and forest fires in Algeria and Ecuador. ISS-based sensors contributing data include the Hyperspectral Imager for the Coastal Ocean (HICO), the ISERV (ISS SERVIR Environmental Research and Visualization System) Pathfinder camera mounted in the US Window Observational Research Facility (WORF), the ISS Agricultural Camera (ISSAC), formerly operating from the WORF, and high resolution handheld camera photography collected by crew members (Crew Earth Observations). When orbital parameters and operations support data collection, ISS-based imagery adds to the resources available to disaster response teams and contributes to the public-domain record of these events for later analyses.

Findings are placed in a context of changing climate, population growth and human water management. We find that many of the world's major mid-latitude aquifers show depletion signals over the 2003-2013 period, posing new challenges for sustainable water management. Concurrently, several high and low-latitude regions demonstrate increasing water storage due to changing hydrological variability. Although our results are consistent with observations of alpine glacial melt and groundwater depletion around the world, we find that global water losses from these regions are mostly compensated by storage gains at high and low latitudes. During the GRACE record (2003-2013), using "top-down" estimates of changing global land mass, we find that recent land contributions to global mean sea level rise are not significantly different from zero.

To improve short-term earthquake forecasts, it is essential to understand the non-seismic processes that take place in Earth's crust during the build-up of tectonic stresses. Days prior to the January 2001 M 7.6 Gujurat earthquake in India, there was a significant increase in the regional CO concentration, reaching 240 ppbv over a 100 squared kilometers, as derived from data of the MOPITT sensor onboard the NASA Terra satellite. A possible explanation for these observations is that when stresses in Earth's crust are building, positive hole charge carriers are activated, which are highly mobile and spread from deep below the earth to the surface. Positive holes act as highly oxidizing oxygen radicals, oxidizing water to hydrogen peroxide. It is hypothesized that, as positive hole charge carriers arrive from below and traverse the soil, they are expected to oxidize soil organics, converting aliphatics to ketones, formaldehyde, CO and CO2. This is tested by using a closed chamber with a slab of gabbro rock. Ultrasound generated by a pair of 50 W, 40 kHz piezoelectric transducers, applied to one end of the gabbro slab was used to activate the positive holes. This created a high concentration of positive holes at the end of the rock that the electrical conductivity through the rock increased more than 1000-fold, while the increase in conductivity through the other end of the gabbro slab was on the order of 100-fold. On the other end of the slab, rock dust and various soils were placed. A stainless steel mesh was also placed over the soil and dust to allow a current to flow through the granular material. When the far end of the slab was subjected to the ultrasound, currents as large as 250 nA were recorded flowing through the length of the gabbro slab and through the dust/soil pile. Dry dust/soil and dust samples impregnated with isopropanol and with a highly reduced butyn containing triple-bonded C and an aromatic ring were used. Multiple tests were conducted to study the interaction of stressed-activated positive hole charge carriers with organic versus inorganic and dry versus moist materials. This study suggests that the appearance of certain trace gases may be useful as a pre-earthquake indicator.

Chromium valence in the olivine crystals was measured with X-ray-Absorption-Near-Edge-Spectroscopy (XANES) at the Advanced Photon Source, Argonne National Laboratory. Chromium K-edge XANES data were acquired with the x-ray microprobe of GSECARS beamline 13-ID-E. Beam focusing was accomplished with dynamically-figured Kirkpatrick-Baez focusing mirrors; this configuration yielded a beam focused to a final spot size of approximately 4 mu m2. Results from the XANES measurements indicate that the ratio of divalent to trivalent Cr in the olivine is systematically correlated with fO2 in a manner that is consistent with the expected redox systematics for Cr2+/Cr3+ in the melt. In this way, measurements of the Cr2+/Cr3+ in olivine phenocrysts can indirectly reveal information about the Cr valence ratio and fO2 the liquid from which it grew even in the absence of a quenched melt phase. Although the results from the experiments presented in this work specifically apply to the Yamato 98 parental liquid, the concepts and XANES analytical techniques used in this study present a novel, generalized methodology that may be applicable to any olivine-bearing basalt. Furthermore, the XANES based measurements are made on a micron-scale, thus potential changes of the Cr2+/Cr3+ in the melt occurring during crystallization may be recorded in detail.

Specifically, the rate of occurrence of earthquakes is inversely proportional to their magnitude m, or more accurately to their scalar moment M. With respect to this "1/f problem," it can be argued that catalog selection (or equivalently, determining catalog constraints) constitutes the most significant challenge to seismicity based earthquake forecasting. Here, we address and introduce a potential solution to this most daunting problem. Specifically, we introduce a framework to constrain, or partition, an earthquake catalog (a study region) in order to resolve local seismicity. In particular, we combine Gutenberg-Richter (GR), rupture length, and Omori scaling with various empirical measurements to relate the size (spatial and temporal extents) of a study area (or bins within a study area), in combination with a metric to quantify rate trends in local seismicity, to the local earthquake magnitude potential - the magnitudes of earthquakes the region is expected to experience. From this, we introduce a new type of time dependent hazard map for which the tuning parameter space is nearly fully constrained. In a similar fashion, by combining various scaling relations and also by incorporating finite extents (rupture length, area, and duration) as constraints, we develop a method to estimate the Omori (temporal) and spatial aftershock decay parameters as a function of the parent earthquake's magnitude m. From this formulation, we develop an ETAS type model that overcomes many point-source limitations of contemporary ETAS. These models demonstrate promise with respect to earthquake forecasting applications. Moreover, the methods employed suggest a general framework whereby earthquake and other complex-system, 1/f type, problems can be constrained from scaling relations and finite extents.

The Global Positioning System satellites have become primary sensors to measure signatures associated with such natural hazards. These signatures typically include GPS-derived seismic deformation measurements, co-seismic vertical displacements, and real-time GPS-derived ocean buoy positioning estimates. Another way to use GPS observables is to compute the ionospheric total electron content (TEC) to measure and monitor post-seismic ionospheric disturbances caused by earthquakes, volcanic eruptions, and tsunamis. Research at the University of New Brunswick (UNB) laid the foundations to model the three-dimensional ionosphere at NASA's Jet Propulsion Laboratory by ingesting ground- and space-based GPS measurements into the state-of-the-art Global Assimilative Ionosphere Modeling (GAIM) software. As an outcome of the UNB and NASA research, new and innovative GPS applications have been invented including the use of ionospheric measurements to detect tiny fluctuations in the GPS signals between the spacecraft and GPS receivers caused by natural hazards occurring on or near the Earth's surface. This continuing research is expected to provide early warning for tsunamis, earthquakes, volcanic eruptions, and meteor impacts, for example, using GPS and other global navigation satellite systems. We will demonstrate new and upcoming applications including recent natural hazards and artificial explosions that generated TEC perturbations to perform state-of-the-art imaging and modeling of earthquakes, tsunamis and meteor impacts. By studying the propagation properties of ionospheric perturbations generated by natural hazards along with applying sophisticated first-principles physics-based modeling, we are on track to develop new technologies that can potentially save human lives and minimize property damage.

Whether this event is part of a semi-regular cycle of anomalously warm conditions or a larger future trend of enhanced surface melt remains to be seen. Here, we provide context for such surface melt events and the related contribution to sea-level rise through the simulation of GrIS surface mass balance during the early-mid Holocene (9 and 6 ka) with elevated orbital forcing relative to today. We use equilibrium AOGCM output to force an energy moisture balance model of the GrIS. The model simulates a significant reduction in surface mass balance at 9 and 6 ka relative to our preindustrial control run. Such melt anomalies are consistent with an increased frequency of melt layers from the GISP2 ice core, as well as with ice margin chronologies indicating enhanced retreat during this time. We will compare these simulations of past surface mass balance with present and future predictions using the climate output from the new AR5 simulations with elevated radiative forcing due to anthropogenic greenhouse gases.

AN - 1692742787; 2015-059224 AB - A Mid-Lithospheric Discontinuity (MLD) has been observed at a depth of approximately 90 km within the continental lithosphere by a wide variety of seismic techniques, including shear wave anisotropy, P and S receiver functions, active-source seismic experiments, SS and PP precursors, and ScS reverberation phases. Proposed geological mechanisms for explaining the MLD include the presence of melt, relict subduction zone accretionary structures, or an abrupt change in composition from frozen-in melts and metasomatism. During the 2013 CIDER summer workshop, our working group began an investigation of the MLD by compiling a seismological database of where the interface has been observed, methods used to identify it, and characteristics (depth, velocity contrast, gradients) of the observations. Additionally, we created a petrological database of xenoliths that originated immediately above, below, and within the vicinity of the seismologically observed structure. We find that regions of thick continental lithosphere, exhibit evidence for an abrupt decrease in seismic shear velocity ( approximately 5% over 10-20 km) at 60-160 km depth, with the majority of observations within approximately 80-90 km. We used the petrological and seismological constraints to then assess the feasibility of a metasomatic and frozen-in melt layer associated with the MLD. We used shear wave velocity data combined with compiled petrological data to determine which hydrous minerals are most likely to have an impact on the shear velocity at the MLD. Preliminary calculations at 1 GPa show that by increasing the composition of hydrous minerals, such as phlogopite, by 5-20% in the rock, noticeable decreases in shear velocity are produced. To further test the feasibility of this explanation, we used standard thermobarometry methods to determine xenolith formation depth for samples containing amphibole and phlogopite, comparing them to the expected MLD pressure range ( approximately 2-5 GPa; 60-160 km). We find that only 25% of amphibole samples formed within the MLD zone, while 90% of phlogopite-bearing xenoliths were formed at approximately 2-5 GPa--suggesting that phlogopite is a possible candidate for decreased velocity observed at MLD depths. We also tested the possibility that frozen-in melts decrease velocities at this depth range using Perple-X petrological modeling. Preliminary results suggest that frozen carbon-rich melts are capable of producing the approximately 5% decrease in shear velocity at MLD depths. We thus conclude that the presence of frozen carbon-rich melts and/or hydrous minerals are viable mechanisms for the creation of the mid-lithospheric discontinuity.

The focus of PCCS is on the "what" that needs to be preserved, rather than the "how." The input to the development of the PCCS has been based on ESIP members' experience with NASA and NOAA missions. The intent has always been to identify a more comprehensive set of items to evolve a robust standard. PCCS development has primarily focused on satellite remote sensing data. However, the DSC recognizes the need to ensure coverage of other types of geoscience data to expand the applicability of PCCS throughout the geoscience data community. Here, we explore the viability of the current PCCS to application towards physical objects within a core repository. We apply the PCCS as a use case to a subset of the cores housed in the Geological Survey of Alabama's core collection. Although the term "use case" may be used in different ways, here we are using the term to define an approach to develop the functional specifications of a system. The model or standard is carried through to design and implementation, and then applied to a particular situation to test the standard for applied use. The current PCCS has identified eight high-level categories, with several content items under each category being further defined. Information for these content items includes a definition and description, an indication of why the item needs to be preserved, quality criteria, and priority for preservation of the item. For the use case of applying PCCS to physical objects in a core repository, we examine the aspects of each item for relevance with respect to the collection. For example, under Category 1, Preflight/Pre-operations, currently identified content items include "Instrument Description" and "Preflight/pre-operational Calibration Data." With respect to the GSA core repository, these might be mapped to "Rig Type/Coring Method", and "Location/Elevation/Tool Calibration." Further investigation will be required to determine how to better define the content mappings. By taking each high-level category and mapping identified content items to content items within our core repository, we shall detail areas in which the emerging PCCS is robust and works well, and areas in which it is weaker and might need refinement or definition of additional categories or content items to be more broadly applied to a wider cross-section of geoscience data.

Many hydrology and water resources applications, however, require water storage estimates at higher spatial resolution, greater temporal frequency, and with greater physical specificity (e.g., groundwater versus soil moisture versus snow) than GRACE alone can offer. The GRACE Data Assimilation System (GRACE-DAS) was developed to merge GRACE information on large-scale TWS anomalies with physically-based advanced Land Surface Models in order to improve model simulation of water storage while disaggregating and downscaling the raw GRACE TWS estimate. The primary assimilation algorithm is a variant of the ensemble Kalman Smoother. In recent years the system has been applied to studies of water resources and drought monitoring over four different continents. These experiences have led to refinements in the assimilation system that include modifications to land surface model parameters and the treatment of irrigation withdrawals, adjustments in the assimilation algorithm for snow updates, and, most recently, the implementation of a gridded observation assimilation capability that allows for a more flexible application of the system. This presentation will provide an overview of current GRACE-DAS capabilities, report on recent innovations in the modeling system, and describe future directions in GRACE data assimilation research and applications.

Water contents were obtained by FTIR in olivine, pyroxene and garnet for 20 well-characterized peridotite xenoliths from the Udachnaya kimberlite (central Siberian craton) and equilibrated at 2-7 GPa [2]. Water contents in minerals do not appear to be related to interaction with the host kimberlite. Diffusion modeling indicates that the core of olivines preserved their original water contents. The Udachnaya peridotites show a broad range of water contents in olivine (6.5+ or -1.1 - 323+ or -65 ppm H2O (2sigma )), and garnet (0 - 23+ or -6 ppm H2O). The water contents of olivine and garnet are positively correlated with modal clinopyroxene, garnet and FeO in olivine. Water-rich garnets are also rich in middle rare earth elements. This is interpreted as the result of interaction between residual peridotites and water rich-melts, consistent with modal and cryptic metasomatism evidenced in the Siberian cratonic mantle [3-4]. The most water-rich Udachnaya minerals contain 2 to 3 times more water than those from the Kaapvaal craton, the only craton with an intact mantle root for which water data is available [5-6]. The highest water contents in olivine and orthopyroxene in this study (> or = 300 ppm) are found at the bottom of the lithosphere (> 6.5 GPa). This is in contrast with the Kaapvaal craton where the olivines of peridotites equilibrated at > 6.4 GPa have 6 GPa is lower or similar (8.4X 1016 to 8.0X 1018 Pa.s-1) to that of the asthenosphere (< or = 3.7x1018 Pa.s-1 [7]). Such lithologies would not be able to resist delamination by the convecting asthenosphere. However, seismology studies [8] as well as the high equilibration pressures of our samples indicate that the Udachnaya cratonic lithosphere is 220-250 km thick. Consequently, the water-rich peridotites are likely not representative of the overall Siberian cratonic lithosphere. Their composition is linked to spatially limited melt metasomatism in mantle regions above asthenospheric upwellings responsible for the kimberlite magmatism prior to their ascent and eruption.

Coastal and marine ecosystems such as mangrove forests contribute to the biodiversity of land and ocean habitats at various scales, acting as direct link to biogeochemical cycles of both upland and coastal regions. All of the positive and negative drivers of change of both natural and anthropogenic, within watershed and political boundaries, play a role in the health and function of these ecosystems. As a result, they are among the most rapidly changing landscapes in the Americas. This research presents a watershed scale monitoring approach of mangrove ecosystems using datasets that contain several sources of remotely sensed data and intensive ecological field data. Spatially exclusive decision tree models were used to assess and monitor land use and land cover change in mangrove ecosystems for different regions of the Americas, representing varying geomorphologic settings across a latitudinal gradient. The integration of ecological, hydrological, and geomorphologic characteristics of the contributing areas to these critical downstream ecosystems is crucial for both mapping and monitoring these vulnerable ecosystems. This research develops the scientific and technical framework needed for advancement in regional scale natural resource management and valuation, informed policy making, and protection of coastal ecosystems. This research also provides a foundation for the development of forecast models to simulate and assess mangrove area, health, and viability changes under different land management and climate scenarios.

The impact and connections of this hydrologic flux with the regional and global climate, biogeochemical cycles, and terrestrial water storages are clearly of great importance. However, little is known about the hydrology and hydraulics of the Congo Basin. The Congo Basin has not experienced the same degree of new research compared to the Amazon in spite of its enormous size because the lack of in situ has limited our hydrologic understanding of the basin. In this study, we integrate multiple satellite measurements; terrestrial water storage (TWS) changes from GRACE, water level changes from radar altimeter, and inundated extents from PALSAR ScanSAR imagery to characterize and quantify TWS change and its surface and subsurface components over the central Congo Basin. Our results indicate that the annual variations of the TWS changes during the period of 2007-2010 range between 21 km3 and 31 km3, and mostly controlled by surface storage changes. Our result is in contrast with a study over another large tropical basin, the Negro River Basin, where the amplitude of the subsurface storage changes represents more than a third of the amplitude of TWS changes. Our findings will contribute to provide a basis for determining and predicting the impacts of climate change and deforestations on the distribution of terrestrial water stores and fluxes in the Congo Basin.

In particular, these differences can place constraints on models of atmospheric tides and solid tides. Such signals arise because altimetry is sensitive to the solid tide while bottom pressure (BP) is not, while BP is sensitive to the air tide while altimetry is not (not directly anyway). I have constructed a database of precise BP tide estimates from 151 deep-ocean stations, most based on multiple years of hourly data. The relationship between bottom pressure and equivalent sea-surface elevation must be carefully handled, since it depends on ocean stratification and the compressibility of seawater. The altimeter-BP rms differences are 5 mm or better. In these differences, the air tide is easily detected at the S1 and S2 periods and more marginally detected at the T2 and K1 periods (the latter represent seasonal sidelines of either S1 or S2); a comparison of various air-tide models favors one derived from recent 3-hourly ECMWF operational analyses. Results also show that altimetry can benefit from correcting for crustal loading by the S2 air tide; the signal is only 1.4 mm or less and has previously been ignored, but it is detectable in the altimeter-BP differences. Similarly altimetry must be corrected for the presence of the air tide in the dry troposphere correction. Finally differences also allow Love numbers to be estimated at the M2, O1, and K1 periods, with the latter clearly showing suppression from the free core-nutation resonance. However, recent estimates just published by Krasna and colleagues, using VLBI data, are far more accurate, in part because VLBI need not contend with large, possibly inconsistent ocean signals in their data. Our results could be improved once baroclininc tides are properly accounted for, but these tides, with wavelengths of order 100 km, are currently insufficiently known and may require wide-swath altimetry before they are accurately mapped.

Mass variations are directly inverted from the inter-satellite K-band range-rate (KBRR) data using a localized mascon approach. Using appropriate constraints, our regional solutions allow better temporal (10-day) and spatial (2-degrees) resolution, than the classical spherical harmonic solutions. In addition altimetry measurements allow the retrieval of the water level variations at a few centimeter level, for major lakes and reservoirs. Because of its smaller footprint (50 to 100 meters, depending on the laser period) compared to radar altimeters (several kilometers), ICESat (Ice, Cloud and Land Elevation satellite) laser altimetry is more suitable for the retrieval of water level variations of small inland bodies, and when water returns can be highly contaminated by land or vegetation. We combine these gravity and altimetry measurements with hydrology models and in-situ measurements in order to describe the continental water storage variations at seasonal timescales and also long-term variations in Africa.

Using the normal-mode formulation, we present our estimates of the source parameters of moment tensor and double-couple for the events of the 2004 Sumatra-Andaman, 2007 Bengkulu, 2010 Maule, 2011 Tohoku-Oki, 2012 Indian Ocean strike-slip earthquakes. For the 2012 Indian Ocean earthquake (the first strike-slip event detected by GRACE), the GRACE gravity data delineate a composite moment of 1.9X1022 N-m regardless of centroid depth, comparing favorably with the total seismic moment of the main ruptures and aftershocks. The smallest event we successfully analyzed with GRACE was the 2007 Bengkulu earthquake with M0 nearly equal 5.0X1021 N-m. We found that the gravity data constrain the focal mechanism with the centroid only within the upper and lower crustal layers for thrust events. Deeper sources (i.e., in the upper mantle) could not reproduce the gravity observation as the larger rigidity and bulk modulus at mantle depths inhibit the interior from changing its volume, thus reducing the negative gravity component. Focal mechanisms and seismic moments obtained in this study represent the behavior of the sources on temporal and spatial scales exceeding the seismic and geodetic spectrum. In addition, the large-scale postseismic gravity changes following the 2004 Sumatra-Andaman, 2010 Maule, and 2011 Tohoku-Oki earthquakes were evident in the GRACE time-series of the moment tensor components. Our preferred interpretation of the long-wavelength postseismic gravity change is biviscous viscoelastic flow. We present our estimates of the Earth viscoelastic structures by delineating a range of transient and steady-state viscosities. Finally, we discuss how these solutions could be used to correct the GRACE observations for the studies on climate change.

Over the last decade, Gravity Recovery and Climate Experiment (GRACE) gravity measurements have enabled estimates of regional ice loss trends in glaciated southern Alaska. However, higher-resolution in situ, aircraft, GPS and other satellite data are being used to study the basin-scale processes responsible for the observed broad-scale seasonal and inter-annual variability of GRACE-derived mass change. Specifically we report on the use Moderate-resolution Imaging Spectroradiometer (MODIS) Land Surface Temperature (LST) and Fractional Snow Cover (FSC) products, at a spatial scale of 1 km or less, to document the temporal and spatial evolution of seasonal processes over a time period that includes the GRACE observations (2002 to present). We use observations of cryospheric change over the last decade as input to 3-D viscoelastic Earth models of southern Alaska. In addition to glacial changes on a variety of temporal and spatial scales, southern Alaska is tectonically active with frequent large earthquakes. The gravimetric response, as well as the rate and orientation of crustal deformation, due to relaxation processes associated with inter-annual snow/ice changes, glacier wastage on time scales of years to decades, and large earthquakes (1964 Prince William Sound, M=9.2, 2002 Denali, Mw=7.9) will be discussed.

The Mayor's proposed $20 billion plan aims to strengthen the City's resilience to coastal inundation. Accordingly, the NPCC2 scientific and technical support team generated a suite of temperature, precipitation, and sea level rise and extreme event projections through the 2050s. The NPCC2 sea level rise projections include contributions from ocean thermal expansion, dynamic changes in sea surface height, mass changes in glaciers, ice caps, and ice sheets, and land water storage. Local sea level changes induced by changes in ice mass include isostatic, gravitational, and rotational effects. Results are derived from CMIP5 model-based outputs, expert judgment, and literature surveys. Sea level at the Battery, lower Manhattan, is projected to rise by 7-31 in (17.8-78.7 cm) by the 2050s relative to 2000-2004 (10 to 90 percentile). As a result, flood heights above NAVD88 for the 100-year storm (stillwater plus waves) would rise from 15.0 ft (0.71 m) in the 2000s to 15.6-17.6 ft (4.8-5.4 m) by the 2050s (10-90 percentile). The annual chance of today's 100-year flood would increase from 1 to 1.4-5.0 percent by the 2050s.

The precise orbit data are crucial for retrieving gravity difference from range-acceleration and for aligning the LOS data particularly in altitude. A relative orbit error of a few cm in position and a few tens mu m/s in velocity is commensurate with the GRAIL ranging instrument noise at a few mu Gal in LOS gravity difference. We quantify the Ka-band instrument noise characteristics, correction by orbital state vector, non-gravitational and tidal forces, and misalignment error along the orbital path. We also examined the LOLA topography data to compute the model gravitational potentials using two approaches; (1) higher-order expansion of finite amplitude relief using spherical harmonic representation of the global topography data (2) Direct integration of numerous tesseroids from the grid topography data. We compare both approaches to compute the high-degree gravitational potentials and discuss the advantage of the second method to exploit the radially- and laterally-variable density within the crust. The power spectrum, as well as the topography correlation and admittance are quantified by upward-continuing the topographic potential, forward-modeling the LOS gravity along the spacecraft trajectory (i.e., Bouguer correction), and comparing with the GRAIL LOS observations. Based on the LOS data analysis from the primary GRAIL mission, we found that the LOS gravity difference observation produced near unity correlation with topography potential out to degree 550, higher than the global estimate from L2 gravity solutions, over the areas covered by the low altitude orbit ( approximately 20 km). The crustal density was estimated to be 2500-2600 kg/m3 with regional variations of about 10%, by minimizing the Bouguer coherence of the GRAIL data at the degree band 150-300, agreeing with the result given in Wieczorek et al. [2013]. Systematic decrease in the density estimates by 3-4% or 100 kg/m3 was also observed at shorter wavelengths (degree band 300-500). To understand this, we test various gravitational potential models from topography with radial stratification of the bulk density, computed from the tesseroid integration approach.

While the eclogite content and, hence, the Mg/Si ratio of approximately 1.3 in the asthenosphere is well constrained, eclogite contents in the lower mantle may be significantly higher with proposed Mg/Si ratios 4% (per 100 K excess temperature) tend to stagnate in the depth range of 300-410 km, and deliver eclogite to the MTZ. Seismic evidence for this process near Hawaii comes from contrasts in physical properties across the 410 measured by underside reflections. Plumes with eclogite contents >6% (per 100 K excess temperature) are predicted to even fail to cross the mid upper mantle altogether. In contrast, mantle downwellings more efficiently transport eclogite back into the lower mantle, although they need to cross a depth range (from 660 to approximately 750 km) in which eclogite becomes positively buoyant. Numerical model results show that only the subset of slabs that stagnate at approximately 660 km depth for timescales > approximately 50 Myr (e.g., Farallon slab) can segregate through convective instability, with harzburgite rising and eclogite sinking to concentrate at the base of the MTZ. Slabs that directly enter the lower mantle (e.g., Tonga slab) instead do not segregate to carry eclogite into the deep. These dynamical mechanisms set up an eclogite filter with accumulation of eclogite in the MTZ, a density trap bordered above and below by maxima and minima in eclogite excess density, and upward fluxes of eclogite out of the MTZ smaller than downward fluxes.
