The spectra show evidence for two dust components with different temperatures. Spanning the peak of the thermal emission, these observations provide strong constraints on the dust mass, temperature, and luminosity, which serve as critical diagnostics for disentangling the origin and heating mechanism of each component. The results suggest that the warmer dust has a mass of approximately 5X 10 (super -4) M (sub []) , originates from newly formed dust in the ejecta, or possibly the cool, dense shell, and is continuously heated by the circumstellar interaction. By contrast, the cooler component likely originates from a circumstellar shock echo that forms from the heating of a large, pre-existing dust shell approximately 0.01-0.05 M (sub []) by the late-time circumstellar interaction. The progenitor wind velocity derived from the blue edge of the He I 1.083 mu m P Cygni profile indicates a progenitor eruption likely formed this dust shell approximately 100 years prior to the supernova explosion, which is consistent with a Luminous Blue Variable progenitor star.

Career limits are intended to restrict late occurring health effects and include a 3% risk of exposure-induced death from cancer and new limits for central nervous system and heart disease risks. Short-term dose limits are used to prevent in-flight radiation sickness or death through restriction of the doses to the blood forming organs and to prevent clinically significant cataracts or skin damage through lens and skin dose limits, respectively. Large uncertainties exist in estimating the health risks of space radiation, chiefly the understanding of the radiobiology of heavy ions and dose rate and dose protraction effects, and the limitations in human epidemiology data. To protect against these uncertainties NASA estimates the 95% confidence in the cancer risk projection intervals as part of astronaut flight readiness assessments and mission design. Accurate organ dose and particle spectra models are needed to ensure astronauts stay below radiation limits and to support the goal of narrowing the uncertainties in risk projections. Methodologies for evaluation of space environments, radiation quality, and organ doses to evaluate limits are discussed, and current projections for lunar and Mars missions are described.

While the systematic evolution of ligands by exponential enrichment (SELEX) is an efficient method for selecting aptamers, it sometimes fails to obtain aptamers with high affinity and so additional improvements are required. We applied a genetic algorithm (GA) to post-SELEX screening as an in silico maturation of aptamers. First, we pre-selected DNA aptamers against prostate specific antigen (PSA) through three rounds of SELEX. To improve the PSA-binding ability of the aptamers, we carried out post-SELEX screening using GA with the pre-selected oligonucleotide sequences. For screening using GA, we replicated the oligonucleotide sequences obtained through SELEX, crossed over and mutated in silico resulting in 20 sequences. Those oligonucleotide sequences were synthesized and assayed in vitro. Then, the oligonucleotides were ranked according to PSA-binding ability and the top sequences were selected for the next cycle of GA operation. After GA operations, we identified the aptamer showing a 48-fold higher PSA-binding ability than candidates obtained by SELEX. The dissociation constant (K D) of the obtained aptamer was estimated to be several tens of nM. We demonstrated sensing of PSA using the obtained aptamer and succeeded in sensing PSA concentrations between 40 and 100nM.

The extraction and processing of oil sands is much more challenging than for light sweet crude oils because of the high viscosity of the bitumen contained within the oil sands and because the bitumen is mixed with sand and contains chemical impurities such as sulphur. Despite these challenges, the importance of oil sands is increasing in the energy market. To our best knowledge this is the first peer-reviewed study to characterize volatile organic compounds (VOCs) emitted from Alberta's oil sands mining sites. We present high-precision gas chromatography measurements of 76 speciated C sub(2)-C sub(10) VOCs (alkanes, alkenes, alkynes, cycloalkanes, aromatics, monoterpenes, oxygenated hydrocarbons, halocarbons and sulphur compounds) in 17 boundary layer air samples collected over surface mining operations in northeast Alberta on 10 July 2008, using the NASA DC-8 airborne laboratory as a research platform. In addition to the VOCs, we present simultaneous measurements of CO sub(2), CH sub(4), CO, NO, NO sub(2), NO sub(y), O sub(3) and SO sub(2), which were measured in situ aboard the DC-8. Carbon dioxide, CH sub(4), CO, NO, NO sub(2), NO sub(y), SO sub(2) and 53 VOCs (e.g., non-methane hydrocarbons, halocarbons, sulphur species) showed clear statistical enhancements (1.1-397) over the oil sands compared to local background values and, with the exception of CO, were greater over the oil sands than at any other time during the flight. Twenty halocarbons (e.g., CFCs, HFCs, halons, brominated species) either were not enhanced or were minimally enhanced (<10%) over the oil sands. Ozone levels remained low because of titration by NO, and three VOCs (propyne, furan, MTBE) remained below their 3 pptv detection limit throughout the flight. Based on their correlations with one another, the compounds emitted by the oil sands industry fell into two groups: (1) evaporative emissions from the oil sands and its products and/or from the diluent used to lower the viscosity of the extracted bitumen (i.e., C sub(4)-C sub(9) alkanes, C sub(5)-C sub(6) cycloalkanes, C sub(6)-C sub(8) aromatics), together with CO; and (2) emissions associated with the mining effort, such as upgraders (i.e., CO sub(2), CO, CH sub(4), NO, NO sub(2), NO sub(y), SO sub(2), C sub(2)-C sub(4) alkanes, C sub(2)-C sub(4) alkenes, C sub(9) aromatics, short-lived solvents such as C sub(2)Cl sub(4) and C sub(2)HCl sub(3), and longer-lived species such as HCFC-22 and HCFC-142b). Prominent in the second group, SO sub(2) and NO were remarkably enhanced over the oil sands, with maximum mixing ratios of 38.7 ppbv and 5.0 ppbv, or 383 and 319 the local background, respectively. These SO sub(2) levels are comparable to maximum values measured in heavily polluted megacities such as Mexico City and are attributed to coke combustion. By contrast, relatively poor correlations between CH sub(4), ethane and propane suggest low levels of natural gas leakage despite its heavy use at the surface mining sites. Instead the elevated CH sub(4) levels are attributed to methanogenic tailings pond emissions. In addition to the emission of many trace gases, the natural drawdown of OCS by vegetation was absent above the surface mining operations, presumably because of the widespread land disturbance. Unexpectedly, the mixing ratios of alpha -pinene and beta -pinene were much greater over the oil sands (up to 217 pptv and 610 pptv, respectively) than over vegetation in the background boundary layer (20 plus or minus 7 pptv and 84 plus or minus 24 pptv, respectively), and the pinenes correlated well with several industrial tracers that were elevated in the oil sands plumes. Because so few independent measurements from the oil sands mining industry exist, this study provides an important initial characterization of trace gas emissions from oil sands surface mining operations.

The profile data are averaged within twelve, 20 degree -wide latitude bins from 55 degree S to 55 degree N and at twelve altitudes from 27.5 to 55.0 km. The separate, 14-yr data time series are analyzed using multiple linear regression (MLR) models that include seasonal, 28 and 21-month, 11-yr sinusoid, and linear trend terms. Proxies are not used for the 28-mo (QBO-like), 11-yr solar uv-flux, or reactive chlorine terms. Instead, the present analysis focuses on the periodic 11-yr terms to see whether they are in-phase with that of a direct, uv-flux forcing or are dominated by some other decadal-scale influence. It is shown that they are in-phase over most of the latitude/altitude domain and that they have max minus min variations between 25 degree S and 25 degree N that peak near 4% between 30 and 40 km. Model simulations of the direct effects of uv-flux forcings agree with this finding. The shape of the 11-yr ozone response profile from SAGE II also agrees with that diagnosed for the stratosphere over the same time period from the HALOE data. Ozone in the middle stratosphere of the northern subtropics is perturbed during 1991-1992 following the eruption of Pinatubo, and there are pronounced decadal-scale variations in the ozone of the upper stratosphere for the northern middle latitudes presumably due to dynamical forcings. The 11-yr ozone responses of the southern hemisphere appear to be free of those extra influences. The associated linear trend terms from the SAGE II analyses are slightly negative (-2 to -4%/decade) between 35 and 45 km and nearly constant across latitude. This finding is consistent with the fact that ozone is estimated to have decreased by no more than 1.5% due to the increasing chlorine from mid-1992 to about 2000 but with little change thereafter. It is concluded that a satellite, solar occultation measurement provides both the signal sensitivity and the vertical resolution to record the stratospheric ozone response to the forcing from the solar uv-flux, as well as those due to any other long-term changes.

N1 - Last updated - 2011-07-21 ER - TY - JOUR T1 - Five Kepler target stars that show multiple transiting exoplanet candidates AN - 1366814874; 2013-044704 AB - We present and discuss five candidate exoplanetary systems identified with the Kepler spacecraft. These five systems show transits from multiple exoplanet candidates. Should these objects prove to be planetary in nature, then these five systems open new opportunities for the field of exoplanets and provide new insights into the formation and dynamical evolution of planetary systems. We discuss the methods used to identify multiple transiting objects from the Kepler photometry as well as the false-positive rejection methods that have been applied to these data. One system shows transits from three distinct objects while the remaining four systems show transits from two objects. Three systems have planet candidates that are near mean motion commensurabilities-two near 2:1 and one just outside 5:2. We discuss the implications that multi-transiting systems have on the distribution of orbital inclinations in planetary systems, and hence their dynamical histories, as well as their likely masses and chemical compositions. A Monte Carlo study indicates that, with additional data, most of these systems should exhibit detectable transit timing variations (TTVs) due to gravitational interactions, though none are apparent in these data. We also discuss new challenges that arise in TTV analyses due to the presence of more than two planets in a system. Copyright (Copyright) 2010. The American Astronomical Society. All rights reserved.

Our study reveals the presence of a luminous (L (sub IR) nearly equal 4.6X10 (super 43) erg s (super -1) ) and extended component of infrared dust emission, not connected with the main bodies of the galaxies, but roughly coincident with the X-ray halo of the group. We fitted the inferred dust emission spectral energy distribution of this extended source and the other main infrared emission components of SQ, including the intergalactic shock, to elucidate the mechanisms powering the dust and polycyclic aromatic hydrocarbon emission, taking into account collisional heating by the plasma and heating through UV and optical photons. Combining the inferred direct and dust-processed UV emission to estimate the star formation rate (SFR) for each source we obtain a total SFR for SQ of 7.5 M (sub []) yr (super -1) , similar to that expected for non-interacting galaxies with stellar mass comparable to the SQ galaxies. Although star formation in SQ is mainly occurring at, or external to the periphery of the galaxies, the relation of SFR per unit physical area to gas column density for the brightest sources is similar to that seen for star formation regions in galactic disks. We also show that available sources of dust in the group halo can provide enough dust to produce up to L (sub IR) nearly equal 10 (super 42) erg s (super -1) powered by collisional heating. Though a minority of the total infrared emission (which we infer to trace distributed star-formation), this is several times higher than the X-ray luminosity of the halo, so could indicate an important cooling mechanism for the hot intergalactic medium (IGM) and account for the overall correspondence between FIR and X-ray emission. We investigate two potential modes of star formation in SQ consistent with the data, fueled either by gas from a virialized hot IGM continuously accreting onto the group, whose cooling is enhanced by grains injected from an in situ population of intermediate mass stars, or by interstellar gas stripped from the galaxies. The former mode offers a natural explanation for the observed baryon deficiency in the IGM of SQ as well as for the steep L (sub X) -T (sub X) relation of groups such as SQ with lower velocity dispersions.

Spitzer Space Telescope MIPS imaging of the entire SNR at 24, 70, and 160 mu m shows an extremely good correlation with X-ray emission, indicating that the SNR's IR radiation is dominated by the thermal emission of swept-up interstellar dust, collisionally heated by the hot shocked gas. Spitzer IRS spectral observations targeted both the Bright Eastern Knot (BEK) of the SNR where a small cloud has been engulfed by the supernova blast wave and outlying portions of the associated molecular cloud that are yet to be hit by the shock front. Modeling the spectra from both regions reveals the composition and the grain size distribution of the interstellar dust, both in front of and behind the SNR shock front. The comparison shows that the ubiquitous polycyclic aromatic hydrocarbons of the interstellar medium are destroyed within the BEK, along with nearly 25% of the mass of graphite and silicate dust grains.

AN - 863416630; pmid-21319629 AB - It has been established that the motion in depth of stimuli visible to both eyes may be signalled binocularly either by a change of disparity over time or by the difference in the velocity of the images projected on each retina, known as an interocular velocity difference. A two-interval forced-choice stereomotion speed discrimination experiment was performed on four participants to ascertain the relative speed of a persistent random dot stereogram (RDS) and a dynamic RDS undergoing directly approaching or receding motion in depth. While the persistent RDS pattern involved identical dot patterns translating in opposite directions in each eye, and hence included both changing disparity and interocular velocity difference cues, the dynamic RDS pattern (which contains no coherent monocular motion signals) specified motion in depth through changing disparity, but no motion through interocular velocity difference. Despite an interocular velocity difference speed signal of zero motion in depth, the dynamic RDS stimulus appeared to move more rapidly. These observations are consistent with a scheme in which cues that rely on coherent monocular motion signals (such as looming and the interocular velocity difference cue) are less influential in dynamic stimuli due to their lack of reliability (i.e., increased noise). While dynamic RDS stimuli may be relatively unaffected by the contributions of such cues when they signal that the stimulus did not move in depth, the persistent RDS stimulus may retain a significant and conflicting contribution from the looming cue, resulting in a lower perceived speed.

Currently satellite-based precipitation estimates exhibit considerable biases, and there have been many efforts to reduce these biases by merging surface gauge measurements with satellite-based estimates. Most of these efforts require timely availability of surface gauge measurements. The new proposed approach does not require gauge measurements in real time. Instead, the Bayesian logic is used to establish a statistical relationship between satellite estimates and gauge measurements from recent historical data. Then this relationship is applied to real-time satellite estimates when gauge data are not yet available. This new scheme is tested over the United States with six years of precipitation estimates from two real-time satellite products [i.e., the Tropical Rainfall Measuring Mission (TRMM) Multisatellite Precipitation Analysis (TMPA) research product 3B42RT and the NOAA Climate Prediction Center (CPC) Morphing technique (CMORPH)] and a gauge analysis dataset [i.e., the CPC unified analysis]. The first 4-yr period was used as the training period to establish a satellite-gauge relationship, which was then applied to the last 2 yr as the correction period, during which gauge data were withheld for training but only used for evaluation. This approach showed that satellite biases were reduced by 70%-100% for the summers in the correction period. In addition, even when sparse networks with only 600 or 300 gauges were used during the training period, the biases were still reduced by 60%-80% and 47%-63%, respectively. The results also show a limitation in this approach as it tends to overadjust both light and strong events toward more intermediate rain rates.

In this study, this issue is further examined using currently available 7-yr version 5 AIRS data (2002-09) to test its dependence on the AIRS data record lengths, AIRS retrieval versions, and MJO event selection and compositing methods employed. The results indicate a strong consistency of the large-scale vertical moist thermodynamic structure of the MJO between different AIRS data record lengths (2.5 vs 7 yr), different AIRS retrieval versions (4 vs 5), and different MJO analysis methods [the extended empirical orthogonal function (EEOF) method vs the multivariate empirical orthogonal function (MEOF) method]. The large-scale vertical moist thermodynamic structures of the MJO between the AIRS retrievals and the ECMWF Interim Re-Analysis (ERA-Interim) products are also compared. The results indicate a much better agreement of the MJO vertical structure between AIRS and ERA-Interim than with the NCEP-NCAR reanalysis, although a significant difference exists in the magnitude of moisture anomalies between ERA-Interim and AIRS. This characterization of the vertical moist thermodynamic structure of the MJO by AIRS and ERA-Interim offers a useful observation-based metric for general circulation model diagnostics.

Part II: Summertime Mean and Diurnal Interactions AN - 856777442; 14248281 AB - Summertime interactions in the North American Regional Reanalysis (NARR) atmospheric water cycle are examined from a user's perspective over the 1980-99 period with a particular emphasis on the diurnal cycle, the nocturnal maximum of precipitation over the Midwest, and the impacts of precipitation assimilation. NARR's full-year mean atmospheric water cycle and its annual variations are examined in Part I of this study. North American summertime (June-August) features substantial convective activity that is often organized on a diurnal scale, although diverse regional diurnal features are evident to various extents in high-resolution precipitation products. NARR's hourly assimilation of precipitation observations over the continental United States allows it to resolve diurnal effects on the water cycle, but in other regions the diurnal cycle of precipitation is imposed from an external reanalysis model. The prominent nocturnal maximum in precipitation across the upper Midwest is captured in NARR, but different precipitation assimilation sources disrupt the propagation of convective systems across the Canadian border. Normalized covariances of NARR's diurnal water cycle component interactions in the nocturnal maximum region reveal a strong relationship between moisture convergence and precipitation, and also measure the way in which the precipitable water column holds a lagged response between evaporation and precipitation. In many regions the diurnal cycle of rainfall is driven by interactions with water cycle components that differ from those driving the seasonal cycle. A comparison between NARR's precipitation and an estimate of the model precipitation prior to precipitation assimilation distinguishes the portion of the water cycle captured in full by the model and that which is value added by the assimilation routine. The nocturnal rainfall maximum is not present in the model precipitation estimate, leading to diurnal-scale biases in the evaporation and moisture flux convergence fields that are not directly modified by precipitation assimilation.

Part I: 20-Year Mean and Annual Interactions AN - 856777302; 14248269 AB - The North American Regional Reanalysis (NARR) atmospheric water cycle is examined from 1980 to 1999 using a budget approach, with a particular emphasis on annual component interactions and the role of hourly precipitation assimilation. NARR's summertime atmospheric water cycle and diurnal component interactions are examined in Part II of this study. NARR's high-resolution reanalysis and precipitation assimilation allow an improved climatology of mean water cycle components over North America, which is very attractive for applications, climate impact assessments, and as a basis for comparison with other products. A 20-yr climatology of precipitation, evaporation, moisture flux convergence, and the residual error term are produced for comparison to observations, other reanalyses and models, and future climate scenarios. Maps of the normalized covariance of annual precipitation with each of the other water cycle components identify regimes of seasonal interaction that form an additional basis for comparison. The annual cycle of assimilated precipitation is compared to high-resolution precipitation products as an example, and points of interest for continuing studies are identified. Analysis of the mean and transient balances reveals a significant effect from NARR's precipitation assimilation scheme, which is investigated using an estimate of NARR's underlying model precipitation (before assimilation), generated using the precipitation assimilation increment as a proxy. Biases of the precipitation assimilation scheme are then characterized spatially and temporally to inform the interpretation of NARR applications and comparisons. These model precipitation estimates reveal a more tightly closed atmospheric water cycle with predominantly excessive precipitation, resulting in too vigorous evaporation and moisture flux convergences. The sign and magnitude of evaporation and moisture flux convergence biases are found to be related to the precipitation assimilation correction and are important to consider in applications of NARR output.

However, with improved modelling capabilities, new challenges arise. For example, the use of the commercial code LS-DYNA, although widely used and accepted in the technical community, often involves high-dimensional, time-consuming and computationally intensive simulations. Because of the computational cost, these tools are often used to evaluate specific conditions and are rarely used for statistical analysis. This paper discusses an approach to capture what is learned from a limited number of LS-DYNA simulations to develop models that allow users to conduct interpolation of solutions at a fraction of the computational time. In this approach, response surface models are used to predict the system time responses to a water landing as a function of capsule speed, direction, attitude, water speed and water direction. Furthermore, these models can also be used to ascertain the adequacy of the design in terms of probability measures. This paper presents a description of the LS-DYNA model, a brief summary of the response surface techniques, the analysis of variance approach used in the sensitivity studies, equations used to estimate impact parameters, results showing conditions that might cause injuries and concluding remarks.

The 2-D synthetic aperture radiometer (2D-STAR) was flown over regional-scale study sites located in AZ, USA, and Sonora, Mexico (SO). The study sites are characterized by a range of topographic relief with a land cover that varies from bare soil to grass and scrubland and includes areas with high rock fraction near the soil surface. The 2D-STAR retrieval of soil moisture was in good agreement with the ground-based estimates of surface soil moisture in both AZ (rmse=0.012 m (super 3) m (super -3) ) and SO (rmse=0.011 m (super 3) m (super -3) ). The 2D-STAR also showed a good performance in the Walnut Gulch Experimental Watershed (rmse=0.014 m (super 3) m (super -3) ) where the surface soil featured high rock fraction was as high as 60%. Comparison of the results with the Polarimetric Scanning Radiometer at the C- and X-band data indicates the superior soil moisture retrieval performance of the L-band data over the regions with high rock fraction and moderate vegetation density.

A parameterized regression developed for rural air was adapted to central Queens, New York City, i.e., considerable fresh emissions. Measurements of the radicals [HO2] and [OH] were available. These provided explicit reference estimates of the predominant terms for chemical ozone production, Po(O3)=k[HO2][NO], of the predominant chemical loss of nitrogen oxides, L(NO2)=k[OH][NO2], and also their ratio. (This is termed a production efficiency for O3.) Chemical modeling supports a robust extension from Po(O3) to total chemical production, P(O3). The two regression variables, [NO] and jHCHOa'radsA-[HCHO], which best explain Po(O3), have low correlation, Ra arrow right 40.2 (variable, interacting urban plumelets?). In our analysis, R2 for Po(O3) (and an estimate for its rate-determining [HO2]) was in the range 0.48-0.81. Signally, the method suggests a quantitative and very local application of descriptions of "VOC limitation" or "NOx limitation" to P(O3) and L(NO2), expressed as dimensionless sensitivity variables. Unexpected sources, transport, or chemistry may be highlighted using only HCHO, NOx, and UV radiation. More complex relationships are needed in a focused analysis of intermediate polluted situations, where timescales or individual sources may give trouble. Here, we find that T is informative, and cooperates with jA-[HCHO] in defining [HO2]. Sensitivities for radicals and NO for Po(O3) are similar a arrow right 40.4, but sensitivities for radicals and NO2 for L(NO2) emphasize NO2. Remaining variability in the statistical estimates of Po(O3) and L(NO2) is modulated by incompletely understood, slowly varying gain factors. Understanding of these gain factors promises a better empirical indicator for Po(O3)/L(NO2). Complete 3-d simulations are not replaced, but this view helps separate sub-problems in the estimation of HO2 and P(O3).

It updates the previous IGRF generation with a definitive main field model for epoch 2005.0, a main field model for epoch 2010.0, and a linear predictive secular variation model for 2010.0-2015.0. In this note the equations defining the IGRF model are provided along with the spherical harmonic coefficients for the eleventh generation. Maps of the magnetic declination, inclination and total intensity for epoch 2010.0 and their predicted rates of change for 2010.0-2015.0 are presented.

Instead, each world has disparate, yet elevated HSE abundances. Late accretion may offer a solution, provided that > or = 0.5% Earth masses of broadly chondritic planetesimals reach Earth's mantle and that approximately 10 and approximately 1200 times less mass goes to Mars and the Moon, respectively. We show that leftover planetesimal populations dominated by massive projectiles can explain these additions, with our inferred size distribution matching those derived from the inner asteroid belt, ancient martian impact basins, and planetary accretion models. The largest late terrestrial impactors, at 2500 to 3000 kilometers in diameter, potentially modified Earth's obliquity by approximately 10 degrees , whereas those for the Moon, at approximately 250 to 300 kilometers, may have delivered water to its mantle.

Individual measurements are analysed statistically to take advantage of both gridded and individual cloud characteristics. The seasonal variations of radiative fluxes for the same types of clouds from different areas are remarkably similar. Although cloud liquid water paths (LWPs) or ice water paths (IWPs) vary considerably for the same types of clouds, their statistical distributions are very stable for different periods and areas, suggesting that the regional differences in dynamics and thermodynamics primarily cause changes in the cloud frequency or coverage and only secondarily in the cloud macrophysical characteristics such as IWPs or LWPs. These results establish a systematic approach of observations for testing modelled cloud statistics and for improving cloud model parameterizations.

Here, we show that AIRE-deficient mice showed an earlier development of myelin oligonucleotide glycoprotein (MOG)-induced experimental autoimmune encephalomyelitis (EAE). To determine the outcome of ectopic Aire expression, we used a retroviral transduction system to over-express Aire in vitro, in cell lines and in bone marrow (BM). In the cell lines that included those of thymic medullary and dendritic cell origin, ectopically expressed Aire variably promoted expression of TRA including Mog and Ins2 (proII) autoantigens associated, respectively, with the autoimmune diseases multiple sclerosis and type 1 diabetes. BM chimeras generated from BM transduced with a retrovirus encoding Aire displayed elevated levels of Mog and Ins2 expression in thymus and spleen. Following induction of EAE with MOG35-55, transplanted mice displayed significant delay in the onset of EAE compared with control mice. To our knowledge, this is the first example showing that in vivo ectopic expression of AIRE can modulate TRA expression and alter autoimmune disease development.

Satellite-observed night lights are used to identify measurement stations located in extreme darkness and adjust temperature trends of urban and periurban stations for nonclimatic factors, verifying that urban effects on analyzed global change are small. Because the GISS analysis combines available sea surface temperature records with meteorological station measurements, we test alternative choices for the ocean data, showing that global temperature change is sensitive to estimated temperature change in polar regions where observations are limited. We use simple 12 month (and n 12) running means to improve the information content in our temperature graphs. Contrary to a popular misconception, the rate of warming has not declined. Global temperature is rising as fast in the past decade as in the prior 2 decades, despite year-to-year fluctuations associated with the El Nino-La Nina cycle of tropical ocean temperature. Record high global 12 month running mean temperature for the period with instrumental data was reached in 2010.

The publication period under review is 2008-2009 and the intention here is to provide readers with a summary of the most influential developments published during this period, across a broad range of topics appropriate to the Earth and environmental sciences. Most authors comment on the ways in which the emphases of research in their specific fields of examination have changed over time. All note an increase in rigor and focus on data quality. Whether advances have taken place in instrumentation, sample manipulation or data deconvolution, there are a large number of dedicated scientists out there contributing to the high quality of geochemical data employed in geological and environmental research.

To better constrain its surface composition and to investigate the possible heterogeneity of the surface of Sedna, several observations have been carried out at ESO-VLT with the powerful spectrometer SINFONI observing simultaneously the H and K bands. The analyzed spectra (obtained in 2005, 2007, and 2008) show a non-uniform spectral signature, particularly in the K band. Spectral modeling using the Shkuratov radiative transfer code for surface scattering has been performed using the various sets of data, including previous observations at visible wavelengths and photometry at 3.6 and 4.5 mu m by the Spitzer Space Telescope. The visible and near-infrared spectra can be modeled with organic materials (triton and titan tholin), serpentine, and H (sub 2) O ice in fairly significant amounts, and CH (sub 4) , N (sub 2) , and C (sub 4) H (sub 6) in varying trace amounts. One of the spectra obtained in 2005 October shows a different signature in the K band and is best modeled with CH (sub 3) OH in place of CH (sub 4) , with reduced amounts of serpentine and with the addition of olivine. The compositional surface heterogeneity can give input on the past history as well clues to the origin of this peculiar, distant object. Copyright Copyright is not claimed for this article.

Inferred H concentration maps have low signal-to-noise (SN) and image restoration (IR) techniques are being studied to enhance results. A single-blind, two-phase study is described in which four teams of researchers independently developed image restoration techniques optimized for LEND data. Synthetic lunar epithermal neutron emission maps were derived from LEND simulations. These data were used as ground truth to determine the relative quantitative performance of the IR methods vs. a default denoising (smoothing) technique. We review and used factors influencing orbital remote sensing of neutrons emitted from the lunar surface to develop a database of synthetic "true" maps for performance evaluation. A prior independent training phase was implemented for each technique to assure methods were optimized before the blind trial. Method performance was determined using several regional root-mean-square error metrics specific to epithermal signals of interest. Results indicate unbiased IR methods realize only small signal gains in most of the tested metrics. This suggests other physically based modeling assumptions are required to produce appreciable signal gains in similar low SN IR applications.

Here, we discuss the temperature threshold below which substantial chlorine activation occurs. We suggest that the onset of chlorine activation is dominated by reactions on cold binary aerosol particles, without formation of polar stratospheric clouds (PSCs), i.e. without significant uptake of HNO sub(3) from the gas-phase. Using reaction rates on cold binary aerosol, a chlorine activation threshold temperature, T sub(ACL), is derived. At typical stratospheric conditions, T sub(ACL) is similar in value to T sub(NAT) the highest temperature at which nitric acid trihydrate (NAT) can theoretically condense to form PSCs. T sub(ACL) is still in use as parameterization for the threshold temperature for the onset of chlorine activation. However, perturbations can cause T sub(ACL) to differ from T sub(NAT): T sub(ACL) is dependent upon H sub(2)O, potential temperature, and the sulphate aerosol loading, but unlike T sub(NAT) is not dependent upon HNO sub(3). A parameterization of T sub(ACL) is provided here, allowing it to be calculated over a comprehensive range of stratospheric conditions. Although considering T sub(ACL) as a proxy for chlorine activation can be no substitute for a detailed model calculation, T sub(ACL) provides a more accurate description of the temperature conditions necessary for polar ozone depletion than T sub(NAT) and can readily be used in place of T sub(NAT).

Exoplanets lying at planet-star separations larger than about 1 AU-where an exoplanet can be resolved from its parent star-have spectra that are dominated by reflected light to beyond 1 mu m and punctuated by molecular absorption features. Here, we consider how exoplanet albedo spectra and colors vary as a function of planet-star separation, metallicity, mass, and observed phase for Jupiter and Neptune analogs from 0.35 to 1 mu m. We model Jupiter analogs with 1X and 3X the solar abundance of heavy elements, and Neptune analogs with 10X and 30X the solar abundance of heavy elements. Our model planets orbit a solar analog parent star at separations of 0.8 AU, 2 AU, 5 AU, and 10 AU. We use a radiative-convective model to compute temperature-pressure profiles. The giant exoplanets are found to be cloud-free at 0.8 AU, possess H (sub 2) O clouds at 2 AU, and have both NH (sub 3) and H (sub 2) O clouds at 5 AU and 10 AU. For each model planet we compute moderate resolution (R = lambda /Delta lambda approximately 800) albedo spectra as a function of phase. We also consider low-resolution spectra and colors that are more consistent with the capabilities of early direct imaging capabilities. As expected, the presence and vertical structure of clouds strongly influence the albedo spectra since cloud particles not only affect optical depth but also have highly directional scattering properties. Observations at different phases also probe different volumes of atmosphere as the source-observer geometry changes. Because the images of the planets themselves will be unresolved, their phase will not necessarily be immediately obvious, and multiple observations will be needed to discriminate between the effects of planet-star separation, metallicity, and phase on the observed albedo spectra. We consider the range of these combined effects on spectra and colors. For example, we find that the spectral influence of clouds depends more on planet-star separation and hence atmospheric temperature than metallicity, and it is easier to discriminate between cloudy 1X and 3X Jupiters than between 10X and 30X Neptunes. In addition to alkalis and methane, our Jupiter models show H (sub 2) O absorption features near 0.94 mu m. While solar system giant planets are well separated by their broadband colors, we find that arbitrary giant exoplanets can have a large range of possible colors and that color alone cannot be relied upon to characterize planet types. We also predict that giant exoplanets receiving greater insolation than Jupiter will exhibit higher equator-to-pole temperature gradients than are found on Jupiter and thus may exhibit differing atmospheric dynamics. These results are useful for future interpretation of direct imaging exoplanet observations as well as for deriving requirements and designing filters for optical direct imaging instrumentation.

The utilized Ief o data set was collected by a truck mounted scatterometer over a corn field and is supported by a comprehensive set of ground measurements, including soil moisture and vegetation biomass. Comparison of Ief o measurement against simulations by the Integral Equation Method (IEM) surface scattering model (Fung et al., 1992) shows that the Ief o measurements are dominated either by an attenuated soil return or by scattering from vegetation depending on the antenna configuration and growth stage. Further, the measured Ief o is found to be sensitive to soil moisture even at peak biomass and large incidence angles, which is attributed to scattering along the soil-vegetation pathway. For the simulation of C-band Ief o and the retrieval of soil moisture two methods have been applied, which are the semi-empirical water cloud model (Attema & Ulaby, 1978) and a novel method. This alternative method uses the empirical relationships between the vegetation water content (W) and the ratio of the bare soil and the measured Ief o to correct for vegetation. It is found that this alternative method is superior in reproducing the measured Ief o as well as retrieving soil moisture. The highest retrieval accuracies are obtained at a 35A incidence angle leading to RMSD's of 0.044 and 0.037m3 ma3 for the HH and VV-polarization, respectively. In addition, the sensitivity of these soil moisture retrievals to W and surface roughness parameter uncertainties is investigated.

On one hand, this approximation greatly simplifies the radiative transfer model, reduces the size of the look-up tables, and makes operational algorithm faster. On the other hand, uncompensated atmospheric scattering caused by Lambertian model systematically biases the results. For example, for a typical bowl-shaped bidirectional reflectance distribution function (BRDF), the derived reflectance is underestimated at high solar or view zenith angles, where BRDF is high, and is overestimated at low zenith angles where BRDF is low. The magnitude of biases grows with the amount of scattering in the atmosphere, i.e., at shorter wavelengths and at higher aerosol concentration. The slope of regression of Lambertian surface reflectance vs. ASRVN bidirectional reflectance factor (BRF) is about 0.85 in the red and 0.6 in the green bands. This error propagates into the MODIS BRDF/albedo algorithm, slightly reducing the magnitude of overall reflectance and anisotropy of BRDF. This results in a small negative bias of spectral surface albedo. An assessment for the GSFC (Greenbelt, USA) validation site shows the albedo reduction by 0.004 in the near infrared, 0.005 in the red, and 0.008 in the green MODIS bands.

In this study, field measurements were applied to develop ocean color satellite algorithms of phytoplankton pigments from in-water radiometry measurements. The match-up comparisons showed that the satellite-derived pigments from our algorithms agree reasonably well (e.g. 30-55% of uncertainty for SeaWiFS and 37-50% for MODIS-Aqua) to field data, with better agreement (e.g. 30-38% of uncertainty for SeaWiFS and 39-44% for MODIS-Aqua) for pigments abundant in diatoms. The seasonal and spatial variations of satellite-derived phytoplankton biomarker pigments, such as fucoxanthin, which is abundant in diatoms, peridinin, which is found only in peridinin-containing dinoflagellates, and zeaxanthin, which is primarily from cyanobacteria in coastal waters, revealed that higher densities of diatoms are more likely to occur on the inner shelf and during winter-spring and obscure other abundant phytoplankton groups. However, relatively higher densities of other phytoplankton, such as dinoflagellates and cyanobacteria, are likely to occur on the mid- to outer-continental shelf and during summer. Seasonal variation of riverine discharge may play an important role in stimulating algal blooms, in particular diatoms, while higher abundances of cyanobacteria coincide with warmer water temperatures and lower nutrient concentrations.

For example, fluorescence observations may provide a means to detect vegetation stress before chlorophyll reductions take place. Although there have been many measurements of fluorescence from ground- and airborne-based instruments, there has been scant information available from satellites. In this work, we use high-spectral resolution data from the Thermal And Near-infrared Sensor for carbon Observation - Fourier Transform Spectrometer (TANSO-FTS) on the Japanese Greenhouse gases Observing SATellite (GOSAT) that is in a sun-synchronous orbit with an equator crossing time near 13:00 LT. We use filling-in of the potassium (K) I solar Fraunhofer line near 770 nm to derive chlorophyll fluorescence and related parameters such as the fluorescence quantum yield at that wavelength. We map these parameters globally for two months (July and December 2009) and show a full seasonal cycle for several different locations, including two in the Amazonia region. We also compare the derived fluorescence information with that provided by the MODIS Enhanced Vegetation Index (EVI). These comparisons show that for several areas these two indices exhibit different seasonality and/or relative intensity variations, and that changes in fluorescence frequently lead those seen in the EVI for those regions. The derived fluorescence therefore provides information that is related to, but independent of the reflectance.

Different techniques of energy estimation in the online and offline pulses are investigated for post processing of lidar returns. The cornerstone of the technique is the accurate estimation of the spectrum of lidar signal and background noise. Since the background noise is not the ideal white Gaussian noise, simple average level estimation of noise level is not well fit in the energy estimation of lidar signal and noise. A brief review of the methods is presented in this paper.

A DUV (<250-nm) source enables the detection of microbes in their native state on natural materials, avoiding background autofluorescence and without the need for fluorescent dyes or tags. We demonstrate that DUV-laser-induced native fluorescence can detect bacteria on opaque surfaces at spatial scales ranging from tens of centimeters to micrometers and from communities to single cells. Given exposure times of 100 ks and low excitation intensities, this technique enables rapid imaging of bacterial communities and cells without irreversible sample alteration or destruction. We also demonstrate the first noninvasive detection of bacteria on in situ-incubated environmental experimental samples from the deep ocean (Lo'ihi Seamount), showing the use of DUV native fluorescence for in situ detection in the deep biosphere and other nutrient-limited environments.

Needlets have been applied successfully to the treatment of astrophysical and cosmological observations, and in particular to the analysis of cosmic microwave background (CMB) data. Usually, such analyses are performed in real space as well as in its dual domain, the harmonic one. Both spaces have advantages and disadvantages: for example, in pixel space it is easier to deal with partial sky coverage and experimental noise; in the harmonic domain, beam treatment and comparison with theoretical predictions are more effective. During the last decade, however, wavelets have emerged as a useful tool for CMB data analysis, since they allow us to combine most of the advantages of the two spaces, one of the main reasons being their sharp localization. In this paper, we outline the analytical properties of needlets and discuss the main features of the numerical code, which should be a valuable addition to the CMB analyst's toolbox.

A key component to our work has been use of dialysis membranes to allow analysis of aqueous and solid components that are not otherwise easily separable. Aqueous speciation determined using voltammetry indicates that the major species for the experiments are Fe(H (sub 2) O) (sub 6) (super 2+) and FeS (sub aq) at pH 7. The equilibrium fractionation factor at 20 degrees C and pH 7 has been determined to be -1.59 + or - 0.28 (2sigma )ppm between Fe(II) (sub aq) (minor FeS (sub aq) also present in the experiment) and mackinawite. Conditions were changed to vary Fe(II) (sub aq) /FeS (sub aq) , and at pH=7, no significant change in fractionation occurred. The magnitude of the fractionation decreased when temperature was increased to 35 degrees C. Isotopic exchange kinetics in the experiments reflects fast exchange across the membrane and slower exchange between aqueous Fe and mackinawite. Precipitation experiments similar to those of Butler et al. (2005, EPSL) were also done, exploring the effects of pH, initial Fe(II) (sub aq) , and time. Our replicate of Butler et al.'s experiments at pH 4, but extended to longer times, show broadly consistent results: over time, the aqueous Fe-mackinawite fractionation decreased and changed from a positive value to more negative values, moving towards the equilibrium fractionation factor. The positive fractionation factor measured by Butler et al. (2005), which is opposite to the equilibrium value, reflects the shorter time of their experiments, which did not erase initial kinetic effects. Experiments at pH 7 show more rapid exchange than those at pH 4 or 8, yet remained far from equilibrium even after 38 days. Experiments with lower initial Fe(II) (sub aq) concentrations show slower exchange, reflecting coarsening of particles over time. The slow exchange kinetics for mackinawite bears on the Fe isotope compositions expected in nature--once formed, mackinawite appears to be quite resistant to later isotopic exchange with ambient fluid or sediment pore water. This in turn has important implications for determining the Fe isotope compositions of sedimentary pyrite, which is often considered to form from FeS precursors.

Microbial mediated oxidation of organic matter, possibly from the localized ponds, is understood to be a driving mechanism in the geochemical transformations by which As is released from the shallow anoxic sediments into the shallow groundwaters. The objective of the current study is to delineate the sources of groundwater recharge (in both high As and low As areas) by identifying regional trends in delta (super 18) O and delta D compositions of the groundwater, surface waters, and precipitation. To understand the kinetics in this recharge process of shallow aquifers, a study has been conducted over 2 field seasons. Regionally in Murshidabad, high dissolved As concentrations are widespread, but local distribution is highly heterogeneous, varying in one area from 0 to >4600 ppb at the same depth within a lateral distance of 20 m. This study incorporated four high As hot spot areas and subsequently compared the geochemical parameters to low As areas both in terms of sediment and water stable isotope chemistry. Dissolved As concentrations increase from west to east in the study region (crossing the river Bhagirathi) for both As (sub T) and As(III) [ approximately 75% of As (sub T) is As(III)], further indicating strongly reducing conditions. A total of 35 water samples were analyzed for stable oxygen and hydrogen isotopes. Chemically distinct groundwaters (Ca-Na-HCO (sub 3) -Cl) have DIC values that indicate CO (sub 2) outgassing, a process which enriches DIC in these waters in heavier oxygen isotopes. Heavier delta (super 18) O values indicate an exchange with atmospheric CO (sub 2) , whereas the lighter values indicate carbonate and/or organic rich components in the matrices. On delta (super 18) O vs delta D plots, the majority of the pond waters lie below both the GMWL and LMWL, whereas the major rivers of this region (Ganges and Bhagirathi) plot above the GMWL with delta (super 18) O values of -8.0ppm to 8.3ppm. The surface pond waters and the groundwaters in high As areas show contrasting slopes when crossplots of the intercept and slope values are plotted. Hence, the groups are statistically distinct. The present data suggest that dry season recharge is a chief source of groundwater in the arsenic hot spots of Murshidabad, West Bengal.

The 1976 Viking mission documented extensive ancient streams and lakes. Later in Martian history, interactions between volcanism, impacts, groundwater and ice sustained liquid water at least locally. On Earth, virtually everywhere we find liquid water we find life. Thus Mars is the prime exploration target for astrobiology. Later missions found that liquid water had extensively altered the ancient crust. ESA's Mars Express Orbiter found phyllosilicates and hydrated silicates. NASA's Mars Reconnaissance Orbiter (MRO) found other geographically extensive phyllosilicates and sulfates. MRO also detected hydrous silica, carbonates and other aqueous minerals; some were associated with ancient deltas, crater lakes and canyons. The Mars Exploration Rover (MER) Opportunity found sulfates, hematite and other minerals that formed in playa lakes and aquifers. MER Spirit found deposits that had been altered by migrating aqueous fluids, and others that are aqueous precipitates, including carbonates and possibly silica. Spirit's discovery of deposits rich in ferric sulfate indicates that the aqueous dissolution and/or alteration of olivine was associated with acidic conditions, as can occur during hydrothermal activity. The oxidation of iron and sulfur in aqueous environments can provide energy for life. Thus habitable environments might have existed in Gusev crater at least intermittently in the geologic past. Also, recent reports of atmospheric methane invoke a robust source(s) located in the subsurface, consistent with liquid water still present at depth. The "follow the water" strategy that has successfully guided recent exploration should now change to "seek signs of habitable environments and life." The 2011 Mars Science Laboratory will perform definitive measurements of diverse minerals, volatiles and any organic compounds at a site that experienced aqueous activity. The 2016 Mars Science Orbiter will identify atmospheric trace gases. Future missions will employ higher-resolution images, precision landings, and new rover-based measurements. Soil, rock and atmospheric samples will be returned to state-of-the-art laboratories on Earth to intensify and extend the search for evidence of life.

A deepening understanding of the diversity of life on Earth, the first discoveries of planets around other stars, and a growing appreciation of the nature of extraterrestrial environments in our solar system all contributed to a recognition that the time was right to focus scientific and technological expertise on studying the origins, evolution, distribution, and future of life in the universe. A cross-disciplinary community of researchers has since been created to pursue questions at the interfaces of geology, paleontology, microbiology, evolutionary biology, geochemistry, astrophysics, planetary science, and philosophy, to name just a few of the disciplines engaged. The NASA Astrobiology Institute (NAI), a virtual research institute currently comprising 14 US teams (with about 600 members total) and 6 international partner organizations, has played a major role in developing this community. I will briefly describe the NAI, and then review some of the scientific research it has supported that is profoundly altering our view of Earth, planetary habitability, and the origin of life.

Because perchlorate is a soluble salt, its distribution through the soil column can illustrate the extent to which the soil has interacted with liquid water. The WCL experiments reported a similar concentration of perchlorate in surface and subsurface samples; although, only three soil samples were run. A more detailed mapping of the perchlorate distribution is needed if we are to understand the processes at work at the site. Here, we use spectra from the Surface Stereo Imager (SSI) aboard Phoenix to map the distribution of perchlorate salts at the Phoenix landing site. We find that perchlorate is concentrated into small subsurface patches with distinct spectral signatures. These patches are morphologically similar to salt patches that form from aqueous redistribution on Earth, for example, in the Antarctic Dry Valleys. We propose that thin films of liquid water, arising from minor melting associated with seasonal ices or long-term obliquity cycles, are responsible for dissolving and concentrating perchlorate into these subsurface patches.

Lunar sample studies over the last decade or so have produced a clear picture of space weathering processes in the lunar environment. By combining laboratory and remote spectra with microanalytical methods (scanning and transmission electron microscopy), we have begun to unravel the various processes (irradiation, micrometeorite bombardment, etc) that contribute to space weathering and the physical and optical consequences of those processes on the Moon. Using the understanding gleaned from lunar samples, it is possible to extrapolate weathering processes to other airless bodies from which we have not yet returned samples (i.e. Mercury, asteroids). Through experiments which simulate various components of weathering, the expected differences in environment (impact rate, distance from Sun, presence of a magnetic field, reduced or enhanced gravity, etc.) and composition (particularly iron content) can be explored to understand how space weathering will manifest on a given body.

The genetic relationship between neighboring small vent fields and the Tharsis Montes remains unclear, and as such the number, sequence and style of additional magma production events related to these fields are not clearly understood. To address this issue the goal of this project is to characterize small vents east of Pavonis Mons in order to understand the number of vent fields, and postulate how these magma production events contributed to the development of the Tharsis region. Mapping of volcanic vents east of Pavonis Mons reveals a variety of small-vents (tens of km in diameter) that may be genetically similar to those belonging to neighboring vent fields. This study uses image data from the Thermal Emission Imaging System (THEMIS), and Context Camera (CTX), as well as topographic information from the Mars Orbiter Laser Altimeter (MOLA). Small-vents were primarily identified based on the presence of radiating lava flow textures from a common topographically distinguishable point or linear fissure. Often a vent forms a topographic high from the accumulation of lava flows and explosive deposits. As such, a local topographic high and/or collapse features with or without rims at the summit were also used as indicators of volcanic vents. Each vent was assigned a two dimensional data point at the center of the inferred eruptive activity to represent the pathway through the crust that the source magma body traveled. Some vents are located in close proximity to one another and appear to be related to one shallow magma chamber. These vents construct a larger volcanic feature that we define as a vent complex. 61 of the total 109 vents are isolated and the remaining 48 vents form a total of 13 vent complexes. In other words, of the total population of 109 vents, there are 74 individual vents and vent complexes. The total number of vents recorded in this study likely represents a minimum of the entire population of volcanic features that exist in our mapping area.

Not only did those involved deal effectively with the extreme limitation in access to and resources available for a target as remote as the lunar surface, but they developed an effective field-based approach for all science activities which included the deployment of field instruments. A recently compiled archive of Apollo field work related documents provides insight into the problem-solving that led to this methodology. The online Apollo Surface Journal allows analysis of the astronaut's actual performance in terms of capability for distance on foot, field station activities, and manual operation of tools and instruments, all as a function of time. Robotic precursors to provide "on the ground" images and orbital coverage at up to 1 meter resolution for potential landing sites were an essential first step. The astronauts had to rely on intensive, lengthy simulation and training to operate "where no man had gone before" innovatively assisted by a co-trained geological "back room". Their limited dexterity in spacesuits led to the development of a systematic oral documentation method. The astronauts became quite effective at communicating and capturing the geological character of field stations accurately and succinctly the first and only time in a matter of tens of minutes, in a systematic, repeatable manner. They were restricted to tens of kilometers in the rover and normally tens of meters on foot. Science objectives were addressed by gathering samples at selected accessible outcrops and determining their relationship to the surrounding terrain as keys to understanding the underlying structure and stratigraphy. These should be effective "lessons learned" for next generation field science activities on the Moon and elsewhere.

These altimetric observations have been used to improve the lunar geodetic grid to approximately 1 m radial and approximately 50 m spatial accuracy with respect to the Moon's center of mass. LOLA has also provided the highest resolution global maps yet produced of slopes, roughness and the 1064-nm reflectance of the lunar surface. Digital elevation models of the lunar polar regions have a spatial resolution of 25 m within 50 km of each pole; the models allow precise characterization of present and past illumination conditions. The current LOLA global topography model has a spatial resolution of approximately 1 km at the equator and improves with increasing north and south latitude. The data are appropriate for investigation of geological processes that have shaped the lunar surface, including impact cratering, volcanism and tectonics, and examples of each of these will be discussed.

As the largest and oldest clearly recognizable impact basin on the Moon, it holds a record of the early cataclysmic bombardment of the Moon and the inner Solar System at a critical time in the evolution of early habitable environments on Earth. The geochemical anomaly that is still associated with the SPA basin reflects components of the lower crust and possibly the upper mantle of the Moon. As such, its materials brought to the surface or incorporated into impact melt rocks hold keys to understanding the lower crust and crust-mantle transition, as well as the thermal evolution of the Moon. Volcanic glasses and basalts from this region of the Moon, far distant from the limited, sampled regions of the near side, will permit a better understanding of mantle heterogeneity that may be associated with global crustal compositional asymmetry. New data provided by recent missions, including Kaguya, Chandrayaan, and LRO, reveal details of the topography, geomorphology, mineralogy, impact deposits, and volcanics that facilitate scientific site selection for sample return. We will describe the objectives and scientific rationale for site selection for the MoonRise mission concept to land in the interior of SPA basin, collect rock samples, and return them to Earth for analysis in terrestrial laboratories. Such samples will include crystalline impact materials that can be used to determine the age of SPA basin formation and of impacts that have occurred subsequently within the basin, thus providing key constraints on the bombardment chronology. These samples will provide ground truth for orbital data and context for interpretation of rock types and mineralogy across the basin, and thus a better understanding of giant impact-basin formation processes and effects. Potential landing sites will be discussed, highlighting new data obtained by recent missions.

The (super 176) Lu- (super 176) Hf (t (sub 1/2) = 37 Ga) decay system has been used extensively to date metamorphic garnets, whereas (super 26) Al- (super 26) Mg (t (sub 1/2) = 0.72 Ma) decay system has found wide applications in the field of early solar system chronology. In this paper we present experimental diffusion kinetic data for these two systems and discuss their chronological and other implications. Our results show that D(Hf (super 4+) ) is around a factor of 30 slower than D(Lu (super 3+) ) in garnet, leading to significant difference in their closure temperatures during cooling of metamorphic rocks. As a consequence, the growth of (super 176) Hf/ (super 177) Hf ratio in a Lu-Hf isochron diagram would be nonlinear because of the diffusive exchange of the parent nuclide ( (super 176) Lu) between garnet and matrix phases after the closure of the radiogenic daughter product, (super 176) Hf (or *Hf) in garnet. This would cause rotation of the Grt-WR "isochron" with the consequence that the (apparent) age derived from the slope of an isochron would be different from the time lapse since the closure of Hf in garnet. In metapelites the ages would be older, with the extent of difference from the closure age of (super 176) Hf depending on the peak temperature (T (sub p) ) experienced by the rock, especially at T (sub p) > 750 degrees C and CR < 5 degrees C/Myr. In addition, significant proportion of the *Hf produced during the prograde path could be retained within typical metapelitic garnets if T (sub p) < 900 degrees C, causing additional complication in the interpretation of Grt-WR "isochrons". With regard to early solar system chronology using (super 26) Al- (super 26) Mg decay system, comparison of D(Mg) data and the consequent T (sub c) (Mg) in melilite with those in other important minerals in CAIs shows that the melilite-age is least susceptible and spinel-age is most susceptible to diffusive resetting during cooling in planetary parent bodies. The evidence of Mg isotopic exchange between melilite and anorthite during nebular processes for a period of approximately 300,000 years, as put forth by Young et al., (2005: Science), implies thermal pulses during nebular processes exceeding 1100-1200 degrees C.

ULCN2005 topography and model crustal thickness data based on the same Clementine topography revealed 38 Quasi-Circular Depressions (QCDs) over and above topographically expressed known named basins, and 27 additional Circular Thin Areas (CTAs), larger than 300 km diameter. Lunar Orbiter Laser Altimeter topography recently provided to the Planetary Data System has far better resolution than ULCN2005 and provides an opportunity to assess how robust were the recognition of QCDs in the earlier ULCN data and also to search for even more subtle topographic signatures of possible additional large impact basins. As before we used a 0 to 5 "topographic expression" scoring system in which very obvious, easily recognized large basins (e.g., named basins like Serenitatis or Crisium) are 5" and basins (including some named features) with no circular topographic low signature are rated 0. Preliminary assessment of the LOLA data suggests that of the 38 new QCDs identified in the ULCN data, 23 received the same topographic expression score, 6 were more easily recognized in the LOLA data (higher expression scores), and 11 had weaker expression scores. 6 previously identified weak candidates received LOLA scores of 0 and 3 others dropped from 2 (possible) to 1 (unlikely). These rare cases were mostly due to resolution differences: what appears in ULCN as a single large roughly circular depression can in the higher resolution LOLA data be a cluster of much smaller QCDs (impact basins). We also find evidence for more than a dozen possible new candidate basins, 9 of which have a preliminary score of 3. Though some basins from the original ULCN study have been eliminated, most have been retained and some new candidates added. The original conclusion that the likely population of very large impact basins on the Moon is at least a factor 2 greater than the traditional number of approximately 45 is supported by the LOLA data.

To help evaluate hardware requirements and operational concepts for future sample-return missions, we designed and built GeoLab--our first generation lab for geological samples--into NASA's Habitat Demonstration Unit in the Pressurized Excursion Module (HDU1-PEM). The center of GeoLab is a glovebox for the examination of samples in a shirt-sleeve environment. As part of a deployable habitat, GeoLab can participate in NASA's analog missions that simulate planetary exploration activities and support the testing of relevant technologies for collecting and handling geological samples. Over time, these tests will evaluate sample handling environments (field and lab), sampling tools and analytical instruments, and different scenarios involving both robotic and human procedures. The GeoLab design supports evolving tests and configurations. The glovebox is mounted on the habitat bulkhead, with three sample pass-though chambers that allow for direct sample transfer into the glovebox from the outside. The glovebox design and construction (low-particle shedding, minimally off-gassing materials) provides a clean environment to reduce sample contamination; in the future, we will integrate a positive pressure, enriched nitrogen atmosphere. The glovebox is equipped with configurable instrument ports. The 2010 test included a mass balance, a stereomicroscope with a HD camera for detailed imaging of samples, and a handheld XRF analyzer for preliminary geochemical characterization of samples. Network cameras provided context imagery and sample handling activities. We present early results from the initial field trial of GeoLab during the 2010 Desert Research and Technology Studies (D-RATS) planetary analog test near Flagstaff, AZ. The 2010 D-RATS mission involved two rovers, the habitat with GeoLab, four crew members, and a team of scientists and flight controllers. The crewed rovers conducted geological traverses and collected samples on the "planetary" surface. Selected samples were transferred into GeoLab for detailed examination and initial analysis, providing critical data to the science team for evaluation and prioritization of samples.

Integrated teams of engineers and scientists have merged exploration technologies with exploration strategies to support these ambitious field tests. The centerpiece of these tests over the past three years has been a prototype planetary rover called the Space Exploration Vehicle (SEV). The SEV has supported near-autonomous operations of a pair of astronauts on simulated planetary missions for up to two weeks. During such traverses, investigations can be conducted from within the pressurized environment of the cabin using a suite of cameras and other sensors. The crew can also conduct extravehicular activities (EVAs) facilitated by the innovative "suitport" hatches that allow quick egress and ingress, greatly increasing the flexibility of EVAs while enabling the crew to quickly recover in the shirtsleeve environment of the SEV. The results of the 2009 D-RATS field test at Black Point Lava Flow (BPLF), AZ: 1) highlighted the critical role of having at least one professional geologist per SEV crew and their bearing on achieving the scientific goals of the mission; 2) pointed out the challenges and opportunities in developing a well-trained geological science support team and procedures for field operations, data analysis and curation; and 3) served as an important test of methodologies for constructing, executing, and modifying traverse/EVA plans, in modalities where reconnaissance data is or is not available and when communications are continuous or intermittent. The recent (8/31-9/13/2010) D-RATS field campaign at BPLF and SP Mountain, AZ involved, for the first time, simultaneous operations of two SEVs, each crewed by a geologist and a professional astronaut. The D-RATS team investigated the best practices for effective science team-crew operations using two communication modes with mission control. The results of the 2010 tests further emphasize the vital role that professional field geologists will play in crewed planetary science missions, including: 1) traverse planning; 2) development of field and operational protocols; 3) crew training; 4) science support operations; 5) and, most importantly, as crewmembers during planetary surface operations.

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

Hydrocarbons, alkyl (wax) esters, sterols, fatty acids, triterpenoids and ether-linked hydrocarbons were analysed using gas chromatography-mass spectrometry (GC-MS) and triterpenoids were analysed using high temperature GC-MS. Cyanobacterial markers were abundant in each sample and lipids diagnostic of heterotrophic bacteria, sulfate-reducing bacteria, anoxygenic phototropic bacteria and archaea were also detected. Limited input from higher plants and diatoms was observed. For the first time, 2-methylhopanoids were detected in Hamelin Pool microbial communities. The overall lipid profiles of the three sediment types were similar, suggesting that extant non-lithified microbial mats and stromatolites can comprise similar microbial communities.

Substantial amounts of the compounds have been detected in all three meteorites, with a total abundance that is lower than that of the amino acids in the same stones. Overall, their molecular distributions mirror closely that of the corresponding amino acids and most evidently so for the LAP meteorite. A surprising l-lactic acid enantiomeric excess was found present in all three stones, which cannot be easily accounted by terrestrial contamination; all other compounds of the three hydroxy acid suites were found racemic. The branched-chain five carbon and the diastereomer six-carbon hydroxy acids were also studied vis-a-vis the corresponding amino acids and calculated ab initio thermodynamic data, with the comparison allowing the suggestion that meteoritic hydroxyacid at these chain lengths formed under thermodynamic control and, possibly, at a later stage than the corresponding amino acids. (super 13) C and D isotopic enrichments were detected for many of the meteoritic hydroxy acids and found to vary between molecular species with trends that also appear to correlate to those of amino acids; the highest delta D value (+3450 ppm) was displayed by GRA 2-OH-2-methylbutyric acid. The data suggest that, while the amino- and hydroxy acids likely relate to common presolar precursor, their final distribution in meteorites was determined to large extent by the overall composition of the environments that saw their formation, with ammonia being the determining factor in their final abundance ratios.

PCR and DNA sequencing of the basidiomycete communities in paired blocks of uninfected and infected trees revealed: (1) that the top, organic soil layer in this system is inhabited almost exclusively by ectomycorrhizal fungi; (2) no difference in species richness (6 species core super(-1) in both) or Shannon-Wiener evenness (0.740 and 0.747 in uninfected and infected blocks respectively), however Shannon-Wiener diversity was significantly greater in infected blocks (1.19 vs 1.94 in uninfected and infected blocks respectively, P < 0.05); (3) significant differences in basidiomycete species composition, with nearly complete absence of two system co-dominant Russula species in infected blocks, and replacement of one co-dominant Piloderma species with another in infected plots, indicating physiological variability within the genus. Soil fungal physiological diversity measured using the Fungilog system was significantly greater in terms of both number of carbon substrates used by culturable soil fungi (both ascomycetes and basidiomycetes) in infected blocks, and the rate at which these substrates were used. Soil enzyme assays revealed greater laccase, peroxidase, and cellulase activities in soils associated with infected trees. Thus, event cascades associated with severe dwarf mistletoe infection not only significantly affected soil fungal species composition and increased species diversity, but also impacted on carbon-related function and functional diversity. Given the geographic range of this pathogen, and forecasts that epidemics of this disease will increase in range in severity with global climate change, these effects have the potential to significantly impact local and global carbon budgets.

The impact of this instrument on geochronological research over the last twenty years has been immense. This is particularly so for lunar geochronology where it has opened up avenues of research that were not possible using conventional TIMS techniques. The great advantage of SHRIMP is that it provides a means for determining precise U-Pb isotopic ratios on selected micron-size areas on polished grains of zircon and other U-bearing minerals. One of the first projects undertaken on the newly invented SHRIMP I was an investigation of U-Pb ages of lunar zircon. Using SHRIMP, multiple analyses could be made on areas of individual zircons to test the stability of U-Pb systems in shocked grains. Also, by analysing grains "in situ", textural relationships between the analysed zircon and the components of the sample breccia could be used in the interpretation of the SHRIMP data. As a result of this research it was realised that most lunar zircons have ages up to 500 Ma older than the Imbrium and Serenitatis impacts at ca. 3.9 Ga, demonstrating that the zircons have not been affected by the these impact events although heating and shock effects have profoundly disturbed other dating systems. This has opened the way for research into the early lunar magmatic and bombardment record. For example, recent SHRIMP results have revealed profound differences in the ages of zircons from breccias from the Apollo 14 and Apollo 17 sample sites, raising new questions about the evolution of lunar magmatism. Also, multiple SHRIMP analyses on complex lunar zircons have shown that these grains can record U-Pb disturbance by later impact events. SHRIMP U-Pb age determinations on phosphates in lunar meteorites has identified lunar events not recognised in samples from the Apollo program. SHRIMP-based research on lunar materials is ongoing and, in combination with other chemical and structural evidence, continues to stimulate new ideas on the early evolution of the Moon.

Forcings that originate in both the region of interest and outside of it are taken into account. It is found that the transient temperature sensitivity parameter ( beta , defined as the observed temperature response per unit forcing) can be better constrained for 50 degree S-25 degree N than for the rest of the globe. The average beta in this region is 0.35 degree C (W m super(-2)) super(-1). The models used in the Intergovernmental Panel on Climate Change Fourth Assessment Report (IPCC AR4) 1% yr super(-1) CO sub(2) increase experiment exhibit a beta in this region that, on average, is higher by 35%. The results show that for 50 degree S-25 degree N beta may provide a more valuable constraint for model evaluation than global mean climate sensitivity.

For this purpose, the Weather Research and Forecasting model (WRF) with the Goddard microphysics scheme is coupled with a Satellite Data Simulation Unit (WRF-SDSU) to facilitate snowfall retrieval algorithms over land by providing a virtual cloud library and corresponding microwave brightness temperature measurements consistent with the GPM Microwave Imager (GMI). When this study was initiated, there were no prior published results using WRF at cloud-resolving resolution (1 km or finer) for high-latitude snow events. This study tested the Goddard cloud microphysics scheme in WRF for two different snowstorm events (a lake-effect event and a synoptic event between 20 and 22 January 2007) that took place over the Canadian CloudSat/Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation (CALIPSO) Validation Project (C3VP) site in Ontario, Canada. The 24-h-accumulated snowfall predicted by WRF with the Goddard microphysics was comparable to that observed by the ground-based radar for both events. The model correctly predicted the onset and termination of both snow events at the Centre for Atmospheric Research Experiments site. The WRF simulations captured the basic cloud patterns as seen by the ground-based radar and satellite [i.e., CloudSat and Advanced Microwave Sounding Unit B (AMSU-B)] observations, including the snowband featured in the lake event. The results reveal that WRF was able to capture the cloud macrostructure reasonably well. Sensitivity tests utilizing both the "2ICE" (ice and snow) and "3ICE" (ice, snow, and graupel) options in the Goddard microphysical scheme were also conducted. The domain- and time-averaged cloud species profiles from the WRF simulations with both microphysical options show identical results (due to weak vertical velocities and therefore the absence of large precipitating liquid or high-density ice particles like graupel). Both microphysics options produced an appreciable amount of liquid water, and the model cloud liquid water profiles compared well to the in situ C3VP aircraft measurements when only grid points in the vicinity of the flight paths were considered. However, statistical comparisons between observed and simulated radar echoes show that the model tended to have a high bias of several reflectivity decibels (dBZ), which shows that additional research is needed to improve the current cloud microphysics scheme for the extremely cold environment in high latitudes, despite the fact that the simulated ice/liquid water contents may have been reasonable for both events. Future aircraft observations are also needed to verify the existence of graupel in high-latitude continental snow events.

The main objective of this algorithm is to detect multilayered cloud scenes, specifically optically thin ice cloud overlying a lower-level water cloud, that present difficulties for retrieving cloud effective radius using single-layer plane-parallel cloud models. The algorithm uses the MODIS 0.94- mu m water vapor band along with CO sub(2) bands to obtain two above-cloud precipitable water retrievals, the difference of which, in conjunction with additional tests, provides a map of where multilayered clouds might potentially exist. The presence of a multilayered cloud results in a large difference in retrievals of above-cloud properties between the CO sub(2) and the 0.94- mu m methods. In this paper the MODIS multilayered cloud algorithm is described, results of using the algorithm over example scenes are shown, and global statistics for multilayered clouds as observed by MODIS are discussed. A theoretical study of the algorithm behavior for simulated multilayered clouds is also given. Results are compared to two other comparable passive imager methods. A set of standard cloudy atmospheric profiles developed during the course of this investigation is also presented. The results lead to the conclusion that the MODIS multilayer cloud detection algorithm has some skill in identifying multilayered clouds with different thermodynamic phases.

Three Joss-Waldvogel disdrometers were operated at a distance of 0.65, 1.05, and 1.70 km in a nearly straight line. The main purpose of the study was to examine the variability of DSDs and its integral parameters of liquid water content, rainfall, and reflectivity within a 2-km array: a typical size of Cartesian radar pixel. The composite DSD of rain events showed very good agreement among the disdrometers except where there were noticeable differences in midsize and large drops in a few events. For consideration of partial beam filling where the radar pixel was not completely covered by rain, a single disdrometer reported just over 10% more rainy minutes than the rainy minutes when all three disdrometers reported rainfall. Similarly two out of three disdrometers reported 5% more rainy minutes than when all three were reporting rainfall. These percentages were based on a 1-min average, and were less for longer averaging periods. Considering only the minutes when all three disdrometers were reporting rainfall, just over one quarter of the observations showed an increase in the difference in rainfall with distance. This finding was based on a 15-min average and was even less for shorter averaging periods. The probability and cumulative distributions of a gamma-fitted DSD and integral rain parameters between the three disdrometers had a very good agreement and no major variability. This was mainly due to the high percentage of light stratiform rain and to the number of storms that traveled along the track of the disdrometers. At a fixed time step, however, both DSDs and integral rain parameters showed substantial variability. The standard deviation (SD) of rain rate was near 3 mm h super(-1), while the SD of reflectivity exceeded 3 dBZ at the longest separation distance. These standard deviations were at 6-min average and were higher at shorter averaging periods. The correlations decreased with increasing separation distance. For rain rate, the correlations were higher than previous gauge-based studies. This was attributed to the differences in data processing and the difference in rainfall characteristics in different climate regions. It was also considered that the gauge sampling errors could be a factor. In this regard, gauge measurements were simulated employing existing disdrometer dataset. While a difference was noticed in cumulative distribution of rain occurrence between the simulated gauge and disdrometer observations, the correlations in simulated gauge measurements did not differ from the disdrometer measurements.

The technique allows detailed comparison of observation impacts in terms of data type, location, satellite sounding channel, or other relevant attributes. This paper describes results for a "baseline" set of observations assimilated by three forecast systems for the month of January 2007. Despite differences in the assimilation algorithms and forecast models, the impacts of the major observation types are similar in each forecast system in a global sense. However, regional details and other aspects of the results can differ substantially. Large forecast error reductions are provided by satellite radiances, geostationary satellite winds, radiosondes, and commercial aircraft. Other observation types provide smaller impacts individually, but their combined impact is significant. Only a small majority of the total number of observations assimilated actually improves the forecast, and most of the improvement comes from a large number of observations that have relatively small individual impacts. Accounting for this behavior may be especially important when considering strategies for deploying adaptive (or "targeted") components of the observing system.

During the campaign, a midlatitude cyclone tracked along the U.S.-Canadian border on 22 January 2007, producing an extensive area of snowfall. Observations of ice crystals from this event are used to evaluate the assumptions and physical relationships for the snow category within the Goddard six-class, single-moment microphysics scheme, as implemented within the Weather Research and Forecasting (WRF) model. The WRF model forecast generally reproduced the precipitation and cloud structures sampled by radars and aircraft, permitting a comparison between C3VP observations and model snowfall characteristics. Key snowfall assumptions in the Goddard scheme are an exponential size distribution with fixed intercept and effective bulk density, and the relationship between crystal diameter and terminal velocity. Fixed values for the size distribution intercept and density did not represent the vertical variability of naturally occurring populations of aggregates, and the current diameter and fall speed relationship underestimated terminal velocities for all sizes of crystals.

In particular, the paper analyzes the difference between 2D and 1D radiative calculations for 2D vertical cross sections of clouds that were observed at three sites over 2-3-yr periods. The results show that 2D effects increase multiyear 24-h average total solar absorption by about 4.1, 1.2, and 0.3 W m super(-2) at tropical, midlatitude, and arctic sites, respectively. However, 2D effects are often much larger than these average values, especially for high sun and for convective clouds. The results also reveal a somewhat unexpected behavior, namely, that horizontal photon transport often enhances solar heating even for oblique sun. These findings underscore the need for fast radiation calculation methods that can allow atmospheric dynamical simulations to consider the inherently multidimensional nature of shortwave radiative processes.

Comparatively little is known, however, about the relative importance of these factors in shaping global fire history. Here we use fire and climate modeling, combined with land cover and population estimates, to gain a better understanding of the forces driving global fire trends. Our model successfully reproduces global fire activity record over the last millennium and reveals distinct regimes in global fire behavior. We find that during the preindustrial period, the global fire regime was strongly driven by precipitation (rather than temperature), shifting to an anthropogenic-driven regime with the Industrial Revolution. Our future projections indicate an impending shift to a temperature-driven global fire regime in the 21st century, creating an unprecedentedly fire-prone environment. These results suggest a possibility that in the future climate will play a considerably stronger role in driving global fire trends, outweighing direct human influence on fire (both ignition and suppression), a reversal from the situation during the last two centuries.

Estimating transition probabilities between habitat states and modeling the factors that influence such transitions have many applications for investigating and managing disturbance-prone ecosystems. We identify the correspondence between multistate capture-recapture models and Markov models of habitat dynamics. We exploit this correspondence by fitting and comparing competing models of different ecological covariates affecting habitat transition probabilities in Florida scrub and flatwoods, a habitat important to many unique plants and animals. We subdivided a large scrub and flatwoods ecosystem along central Florida's Atlantic coast into 10-ha grid cells, which approximated average territory size of the threatened Florida Scrub-Jay (Aphelocoma coerulescens), a management indicator species. We used 1.0-m resolution aerial imagery for 1994, 1999, and 2004 to classify grid cells into four habitat quality states that were directly related to Florida Scrub-Jay source-sink dynamics and management decision making. Results showed that static site features related to fire propagation (vegetation type, edges) and temporally varying disturbances (fires, mechanical cutting) best explained transition probabilities. Results indicated that much of the scrub and flatwoods ecosystem was resistant to moving from a degraded state to a desired state without mechanical cutting, an expensive restoration tool. We used habitat models parameterized with the estimated transition probabilities to investigate the consequences of alternative management scenarios on future habitat dynamics. We recommend this multistate modeling approach as being broadly applicable for studying ecosystem, land cover, or habitat dynamics. The approach provides maximum-likelihood estimates of transition parameters, including precision measures, and can be used to assess evidence among competing ecological models that describe system dynamics.

The entire 5-yr OTD dataset for CONUS is analyzed. The statistical distributions of a variety of optical characteristics are examined, including five flash-level attributes (radiance, area, duration, number of optical groups, and number of optical events), and two group-level attributes [the maximum number of events in a group (MNEG), and a closely related parameter, the maximum group area (MGA)]. On average, there were 5.6 optical groups per return stroke in a ground flash, which is in part due to the likelihood that OTD detects interstroke K changes. It was found that return strokes within ground flashes typically produce large optical groups; hence, the MNEG and MGA parameters serve as useful "return-stroke detectors." The results of this study provide insight on how to construct an algorithm for retrieving the fraction of ground flashes in a set of flashes observed from a satellite lightning imager. Specifically, even though it is shown that the statistical distributions of the optical characteristics for ground and cloud flashes overlap substantially, the mean values of these distributions differ. Hence, a retrieval method that is based on an analysis of the distribution of the means, and that employs the central limit theorem of statistics, is recommended. As the sample size used to compute the means is increased, the overlap in the distributions of the means for ground and cloud flashes is diminished, making ground flash fraction retrieval feasible. Of the seven optical characteristics examined here, the mean MNEG and mean MGA parameters are suggested as being the most useful for discriminating between ground and cloud flashes in the context of this "central limit theorem" approach.

At the South Pole, short-lived species (such as the alkenes) typically were not observed above their limits of detection because of long transit times from source regions. Peak mixing ratios of the longer lived species with anthropogenic sources were measured in late winter (August and September) with decreasing mixing ratios throughout the spring. In comparison, compounds with a strong oceanic source, such as bromoform and methyl iodide, had peak mixing ratios earlier in the winter (June and July) because of decreased oceanic production during the winter months. Dimethyl sulfide (DMS), which is also oceanically emitted but has a short lifetime, was rarely measured above 5pptv. This is in contrast to high DMS mixing ratios at coastal locations and shows the importance of photochemical removal during transport to the pole. Alkyl nitrate mixing ratios peaked during April and then decreased throughout the winter. The dominant source of the alkyl nitrates in the region is believed to be oceanic emissions rather than photochemical production due to low alkane levels. Sampling of other tropospheric environments via a Twin Otter aircraft included the west coast of the Ross Sea and large stretches of the Antarctic Plateau. In the coastal atmosphere, a vertical gradient was found with the highest mixing ratios of marine emitted compounds at low altitudes. Conversely, for anthropogenically produced species the highest mixing ratios were measured at the highest altitudes, suggesting long-range transport to the continent. Flights flown through the plume of Mount Erebus, an active volcano, revealed that both carbon monoxide and carbonyl sulfide are emitted with an OCS/CO molar ratio of 3.3x10 super(-3) consistent with direct observations by other investigators within the crater rim.

Biomass burning influences were widespread throughout the ARCTAS campaign. MODIS data from 2000 to 2009 indicated that 2008 had the second largest fire counts over Siberia and a more normal Canadian boreal forest fire season. Near surface arctic air in spring contained strong anthropogenic signatures indicated by high sulfate. In both spring and summer most of the pollution plumes transported to the Arctic region were from Europe and Asia and were present in the mid to upper troposphere and contained a mix of forest fire and urban influences. The gas/aerosol composition of the high latitude troposphere was strongly perturbed at all altitudes in both spring and summer. The reactive nitrogen budget was balanced with PAN as the dominant component. Mean ozone concentrations in the high latitude troposphere were only minimally perturbed (<5ppb), although many individual pollution plumes sampled in the mid to upper troposphere, and mixed with urban influences, contained elevated ozone (O3/CO=0.11Ac0.09v/v). Emission and optical characteristics of boreal and California wild fires were quantified and found to be broadly comparable. Greenhouse gas emission estimates derived from ARCTAS-CARB data for the South Coast Air Basin of California show good agreement with state inventories for CO2 and N2O but indicate substantially larger emissions of CH4. Simulations by multiple models of transport and chemistry were found to be broadly consistent with observations with a tendency towards under prediction at high latitudes.

NK cell cytotoxicity is mainly regulated by the interaction of activating and inhibitory killer immunoglobulin-like receptors (KIRs) with their respective ligands. To investigate the impact of KIRs and their ligands on haematopoietic SCT outcome, we performed a retrospective study of 78 transfusion-dependent thalassaemia patients (median age 10 years, range 1-29 years) transplanted from an unrelated donor selected using high-resolution molecular typing for both class I and II loci after a myeloablative conditioning regimen. GVHD prophylaxis consisted of CsA, short-term MTX and anti-thymocyte globulin in all patients. We found that patients transplanted from donors homozygous for KIR haplotype A had a greater risk of developing grade II-IV acute GVHD compared with those transplanted from a donor carrying at least one B haplotype (hazard ratio=4.5, 99% confidence interval=1.2-17.1, P=0.003). Our study suggests that KIR genotyping of donor and recipient pairs could contribute to the identification of patients at high risk for developing severe complications of haematopoietic SCT and thus may help with the choice of intensity of GVHD prophylaxis.

The widespread presence during this period of biomass burning effluent, both gaseous and particulate, has been reported. Unusually high ozone readings for this time of year were recorded at surface ozone monitoring sites from northern Alaska to northern California. At Barrow, Alaska, the northernmost point in the United States, the highest April ozone readings recorded at the surface (hourly average values >55aappbv) in 37 years of observation were measured on April 19, 2008. At Denali National Park in central Alaska, an hourly average of 79aappbv was recorded during an 8-h period in which the average was over 75aappbv, exceeding the ozone ambient air quality standard threshold value in the U.S. Elevated ozone (>60aappbv) persisted almost continuously from April 19-23 at the monitoring site during this event. At a coastal site inaanorthern California (Trinidad Head), hourly ozone readings were >50aappbv almost continuously for a 35-h period from April 18-20. At several sites in northern California, located to the east of Trinidad Head, numerous occurrences of ozone readings exceeding 60aappbv were recorded during April 2008. Ozone profiles from an extensive series of balloon soundings showed lower tropospheric features at a141-6aakm with enhanced ozone during the times of elevated ozone amounts at surface sites in western Canada andaathe U.S. Based on extensive trajectory calculations, biomass burning in regions of southern Russia was identified as the likely source of the observed ozone enhancements. Ancillary measurements of atmospheric constituents and optical properties (aerosol optical thickness) supported the presence of a burning plume at several locations. At two coastal sites (Trinidad Head and Vancouver Island), profiles of a large suite of gases were measured from airborne flask samples taken during probable encounters with burning plumes. These profiles aided in characterizing the vertical thickness of the plumes, as well as confirming that the plumes reaching the west coast of North America were associated with biomass burning events.

Aircraft lidar flights were conducted in June 2003 and February 2007. While the ground PM2.5 (particulate matter with diametera[control][curren]2.5I14m) concentration was highest in the winter, the aerosol optical depth (AOD) measured from the MODIS and lidar instruments was highest in the summer. A multiyear seasonal comparison shows that PM2.5 in the winter can exceed summer PM2.5 by 68%, while summer AOD from MODIS exceeds winter AOD by 29%. Warmer temperatures and wildfires in the summer produce elevated aerosol layers that are detected by satellite measurements, but not necessarily by surface particulate matter monitors. Temperature inversions, especially during the winter, contribute to higher PM2.5 measurements at the surface. Measurements of the mixing layer height from lidar instruments provide valuable information needed to understand the correlation between satellite measurements of AOD and in situ measurements of PM2.5. Lidar measurements also reflect the ammonium nitrate chemistry observed in the San Joaquin Valley, which may explain the discrepancy between the MODIS AOD and PM2.5 measurements.

These results are relevant to the ongoing modeling of Cassini CIRS observations of Titan's winter pole. Ices studied are: HCN, hydrogen cyanide; C (sub 2) N (sub 2) , cyanogen; CH (sub 3) CN, acetonitrile; C (sub 2) H (sub 5) CN, propionitrile; and HC (sub 3) N, cyanoacetylene. For each of these molecules, we also report new cryogenic measurements of the real refractive index, n, determined in both the amorphous and crystalline phases at 670 nm. These new values have been incorporated into our optical constant calculations. Spectra were measured and optical constants were calculated for each nitrile at a variety of temperatures, including, but not limited to, 20, 35, 50, 75, 95, and 110 K, in both the amorphous phase and the crystalline phase. This laboratory effort used a dedicated FTIR spectrometer to record transmission spectra of thin-film ice samples. Laser interference was used to measure film thickness during condensation onto a transparent cold window attached to the tail section of a closed-cycle helium cryostat. Optical constants, real (n) and imaginary (k) refractive indices, were determined using Kramers-Kronig analysis. Our calculation reproduces the complete spectrum, including all interference effects.

The methods used for MER on Mars--how, when and in what order measurements or observations are taken--have been examined in order to determine best practices suitable for conducting remote geology on the Moon. To test some of the methods, we have conducted a field test at Cerro de Santa Clara, New Mexico, a region containing volcanic necks and features of varying morphologies, ages and mineralogies. The science goal was to locate, identify and characterize materials analogous to geologic materials important for the study of the lunar South Pole-Aitken Basin. No rover mock-up or science instruments were used. Instead, at each site a rover science team broke down observational "days" into detailed analysis of three targets of interest. Images simulating a high-resolution stereo imager and a hand lens-scale imager were taken using a professional SLR digital camera with interchangeable lens capability and megapixel imaging. Following data collection and analysis, a field team examined each site using traditional terrestrial field methods, facilitating comparison between what was revealed by human versus rover-inspired methods. We conclude from this field test that a methodology similar to that used for MER can be adapted for use on the Moon if mission goals are focused on reconnaissance. But if the science goals require higher-level detail, such as identification, characterization and mapping of specific minerals, a different methodology will be needed. We note also that the amount of time the rover science team spent planning observations significantly lessened the time available to analyze acquired data, and thus decreased the usefulness of that data. In a lunar environment where communication may potentially be much more rapid than for MER, this fact may significantly affect science return.

Results indicate that robotic follow-up is well suited to: 1) testing of hypotheses generated, but not tested, during time-limited fieldwork and arising from later analysis; 2) refining and augmenting data gathered during field traverses and EVAs; 3) rote or long-duration data collection (e.g. LiDAR, Gigapan, GPR) tasks. In this experiment, a geologist and geophysicist with limited prior knowledge of the field site, but with access to a DEM, a panchromatic Quickbird image, black-and-white aerial photography, and low-resolution ASTER data were asked to plan and execute motorized field traverses that included short EVAs conducted on foot in unpressurized concept space suits. Traverses in July-August 2009 were designed to test: 1) a geologic map constructed from the remotely sensed data; and 2) for the presence of ground ice associated with gullies and ice-wedge polygons near the crater rim. Field photographs, rock samples, hand-held GPR traverses, remotely-sensed SAR data, and traverse surface roughness photographs were analyzed and the geologic map refined prior to robotic follow-up the following year. Remotely operated robotic follow-up conducted in August 2010 provided Gigapan, LiDAR, XRF, GPR and microscopic imaging for a small number of sites and locales whose careful selection was informed by all prior work. Robotic follow-up to geological mapping proved particularly valuable for evaluating the structure and morphology of the inner crater wall, mapping faults/fractures in rocks proximal to the crater rim, and understanding the target sequence stratigraphy. For geophysical survey applications, robotic follow-up provided precise metrics for quantifying volumes, depths, concentration, and large-scale distributions of ground ice. Though development of robotic protocols and field procedures is still in its infancy, this experiment demonstrates the exceptional promise of robotic follow-up to human exploration as a planetary exploration field technique.

Therefore, it seems reasonable to assume that some of the guiding principles and lessons learned from Apollo regarding crew geology training will be useful to the planning for any new manned exploration missions (Moon/Mars/Asteroids). The Apollo astronauts received extensive geologic field training to insure maximum scientific gain and also to reduce risk to the EVA team. These field exercises proved to be invaluable and contributed greatly to the achievement of all lunar surface science objectives (including intelligent sample acquisition and documentation). Post mission debriefs indicate that the Apollo astronauts felt that they had been too rigidly scheduled during their surface EVA's and recommended that this should change. They also stated that the crew should be "essentially autonomous" and have a more dynamic role in mission planning. Apollo 17 geologist astronaut, H. H. Schmitt, estimated that during Apollo, the scientists had acquired 75% of the operations skills of the pilots in the program, while the latter had attained 25% of the field geology skills typical of active field geologists. So when should the astronaut field geology training program begin? We feel that it is not too early to begin preparing for these exploration missions now because: (1) The art and skill of Field Geology can only be learned by being in the field. (2) Additionally, Field Geology is a cumulative science, meaning the more experience you get the better you get. (3) The links should be forged between the science, operations, and astronaut communities now because it will take time to achieve the collective experience level necessary for the proper interaction of these communities. The establishment of an ongoing program of scientific field exercises geared toward planetary surface exploration will allow astronauts to gain valuable experience in managing a field research program, practice on site decision making, cope with changing research strategies, and to develop the cross training necessary for a successful expedition. Training the current cadre of astronauts is also important because some will have senior management positions by the time we are ready for this new phase of exploration.

Analog sites are often chosen to serve as many functions as possible. However, the most important consideration in the use of an analog site is its fidelity for the usage sought. The Black Point Lava Flow (BPLF) site used by NASA's Desert RATS field tests is an example we examine. As a site in northern Arizona presenting basaltic lava flows and relatively simple background geology, the site is a good analog for Moon and Mars work in that: i) it presents a dominant rock composition that is, to first order, relevant to the Moon and Mars, ii) its climatic setting is semi-arid; iii) it allows basic planetary geology training; and iv) it is easy and affordable to access. The site also offers a range of Moon and Mars-relevant terrain types and topography, from rough boulder-filled slopes to soft sandy flats, each presenting relevant challenges for rover mobility tests. However, the BPLF site may be inadequate as a driver of requirements for lunar surface science operations. At BPLF, crews of the Space Exploration Vehicle (SEV), a concept vehicle for future pressurized rovers, are asked to frequently conduct EVA, rock hammer in hand, to access outcrops of bedrock and collect fresh samples. In spite of the SEV's high mobility, the geologic tasks are operationally complex enough that EVAs are required. The "lesson learned" is that EVAs are required for rock sampling, and frequently so. However, this lesson may be invalid, at least for the Moon. 95% of all rock samples collected during Apollo (mare and highlands combined) were float. The samples were collected with tongs, not rock hammers. Had the Apollo astronauts disposed of an SEV equipped with a robotic arm, their samples could well have been collected mostly without conducting EVAs. Thus, on the Moon, EVAs may not be required for rock sampling as frequently as implied from field studies at BPLF. Sites on Earth with surfaces dominated by float and/or rubble may offer better science operations analogs for the Moon, even if rock composition is a poorer match. We propose a strategy allowing a more optimal use of terrestrial analog sites for planetary geology.

We can imagine an array of portable, multi-use tools that can be employed by astronaut explorers and their robotic counterparts to elucidate subtle distinctions among geologic map units or to "high-grade" samples for return to Earth laboratories. One smart tool that may be extremely useful for such purposes is a small, portable X-ray fluorescence (XRF) spectrometer. In a manned mission, astronauts can be trained to use the XRF data, along with high-resolution context images, to make informed decisions about which are the most valuable samples to return. The effectiveness of tools such as the XRF is being examined in the context of both the NASA Ames K10 robot test at the Haughton-Mars Project site on Devon Island, Canada, and in the Space Exploration Vehicle (SEV) at the NASA Desert RATS field test at Black Point Lava Flow, Arizona. Both of these activities use orbital images to plan traverses, and field data is collected along these traverses to produce a comprehensive geologic understanding of the analog site in question. The K10 robot was tested as a robotic follow-up mission to a manned traverse in and around Haughton Crater in July-August 2010. The XRF was used to get a basic understanding of the surface geochemistry of the region. Systematic transects were made using the robot to understand the overall region's geochemistry, as well as any changes visible as the robot moved across the surface. During the Desert RATS test in September 2010, the XRF will be used as part of a prototype geologic laboratory designed for planetary surface operations. In this context, the XRF is used to get a first-hand look at a sample's geochemistry in order to high-grade samples for a return mission.

Crews on future long duration missions will likely have the opportunity to plan traverses in real-time based on previous science-driven EVAs, reconnaissance sorties, and exploration strategies tested during analog missions on Earth. Right now mission managers are interested in best enabling science during future missions by learning the strategies and philosophies used by terrestrial field geologists. For example, the metrics acquired on all aspects of geological field traverses on Earth can be used as guidelines in planning future sorties staged from a planetary outpost. Multi-year, reconnaissance field mapping projects carried out by the Geological Survey of Canada (GSC) in remote areas of the Arctic Islands provide a unique opportunity to record the results of science-driven field traverses on a large scale. The targeted objectives for the field season are defined using remote predictive maps constructed from existing maps of bedrock geology and topography; LANDSAT, GEOEYE and SPOT 5 images; air photographs; and geophysical data. Once on site, field mapping teams rely on a combination of digital mapping technologies and traditional field methods to record observations and measurements, all of which are integrated at Base Camp into a Geographic Information System (GIS). The resulting databases uniquely record each step in the planning, execution, and analysis of geological transects carried out by field teams over a period of several weeks. In this paper we present a preliminary analysis of the metrics recorded during 200 geological foot traverses spread over an area of 4000 km (super 2) from the GSC Minto Base Camp located on Victoria Island, Northwest Territories (N71.617787 degrees W115.438987 degrees ). Over the course of the summer field season, 21 geologists carried out an average of 8 field traverses a day, recording data at over 2000 ground stations within the targeted study area. Particular attention is given in the paper to the (1) logistics and planning of reconnaissance vs. detailed mapping traverses carried out during the field season, (2) the decision-making process and impact of real time changes in the field, and (3) lessons learned for future exploration missions on planetary surfaces.

Planning for renewed field exploration of the Moon depends on the selection, training, and capabilities of explorers; selection of landing sites; and the adopted operational approach to extravehicular activity. Apollo geological exploration, and subsequent analysis and interpretation of findings and collected samples, underpin our current understanding of lunar origin and history. That understanding continues to provide new and important insights into the early histories of the Earth and other bodies in the Solar System, particularly during the period when life formed and began to evolve on Earth and possibly on Mars. Specific new lunar exploration objectives include: (1) testing the consensus "giant impact" hypothesis for the origin of the Moon; (2) testing the consensus impact "cataclysm" hypothesis; (3) determining the temporal flux of large impacts in the inner Solar System; and (4) investigating of the internal structure of the Moon. Apollo samples also identified significant and potentially commercial lunar resources that could help satisfy future demand for both terrestrial energy alternatives and space consumables. Equipment necessary for successful exploration consists of that required for sampling, sample documentation and preservation, communications, mobility, and position knowledge. Easily used active geophysical, portable geochemical, and in-situ petrographic equipment can greatly enhance the scientific and operational returns of extended exploration over that possible during the Apollo Program.

Although the presence of ice in the lunar subsurface is supported by an increasing set of remote sensing observations, its depth, composition, and concentration remain poorly quantified. Quantifying these parameters will increase our understanding of the ice transport to the lunar surface and are vital to future plans to use it as a potential resource for long-term human presence. Future EVAs and robotic follow-up are hence crucial to characterize the ice budget at the lunar poles. To address this, a two-year analog experiment using simulated EVAs and robotic follow-up was designed to simulate geologic and geophysical fieldwork to map volatiles on the moon. In 2009, we simulated a 9-hour geophysical survey EVA in concept space suits and motorized traverses in a simulated rover at Haughton crater, Devon Island, Canada. The main objective was to explore for ice along the western crater rim. Two ground penetrating radars (GPR) with four antennas with different probing depths, resolutions, and operational constraints, were mounted on the rover and also deployed manually. Traverses along the crater rim were designed to visit areas where gullies have been observed in high-resolution visible images and that have anomalous polarimetric signatures in L- and X-Band Synthetic Aperture Radar (SAR) images. Observations suggest the presence of ice in the subsurface. GPR has been used explore the depth and the state of this ice in the shallow subsurface and to optimize shallow sampling to better understand the presence of volatiles. In 2010, a follow-up mission was performed using the LiDAR, GPR, panoramic- and micro-imaging cameras, and XRF instruments on the Ames K10 robot to re-explore the sites. The main objective of the robotic follow-up was to provide measurements to quantify ice depth, concentration, and large-scale distribution. Both the LiDAR and panoramic images provided a correlation between gully depth, surface polygon sizes, and ice layer depth as determined with GPR.

Limitations of both time and resources on the Moon led to operational modes that required highly choreographed field traverses. Such constraints rob field geologists of one of their more powerful research tools: observational flexibility. The greatest science return from future human exploration of the Moon, near-Earth asteroids, and Mars will be achieved if we find a way to increase the autonomy of astronaut explorers and encourage them to do field geology more like their compatriots who do field geology on Earth. In this presentation, we review the scientific successes of Apollo, and suggest how a more flexible exploration strategy might have advanced our understanding of lunar evolutionary processes even farther. Operationally, such a strategy will require deliberate action on the part of space-fearing nations to recruit trained field geologists as astronauts. Time and resource limitations and excessive risk can be overcome by an aggressive program of collaborative human and robotic exploration. Robotic precursor missions would provide increasingly sophisticated (and higher resolution) reconnaissance of sites being considered for human exploration. Robotic assistants can be deployed during human missions to perform time-consuming geologic surveys or high-risk activities. Informed by the results of human field research, robots also can perform follow-up scientific activities to expand on our geologic knowledge of a targeted region. Analog exercises on Earth are an essential part of the preparations necessary for successful advanced planetary field geology. These exercises will be most informative if they embrace the entire geologic research process--including problem definition, field observation, and laboratory analysis--and not simply field work. We would argue that terrestrial field geology itself is overdue for a renaissance in which new technologies--including field robotics--will increase the science return of this most fundamental of geologic research activities. Terrestrial field geologists as well as planetary scientists can gain much from greater collaboration.

The aim is to maximize science return within a developing engineering framework, in part, by understanding how field work is ideally conducted. Although inherent to field geologists, it is difficult to explain in a conference room. Here we discuss our approaches to demonstrate the practices of a field geologist to NASA engineers. To communicate our field strategies we designed field work in ways that enabled us to visually demonstrate how field plans were built and modified. Our research focuses on lava sheet inflation at the McCartys flow, NM, and the 1859 Mauna Loa flow, HI. GPS tracks show how our paths changed from a daily plan, and how our overall plan developed over multiple visits. Comparing our GPS tracks and an Apollo-style plan showed the difference between a planned, straight-line path between points and actual field work. Our plan was designed for 8 hours, covering a roundtrip distance of 8.75 km. We did not complete the plan due to unanticipated sample collections, extended observations at stations and terrain navigation, although we achieved the day's objectives. Although it appeared that we covered less ground, we walked 9.1 km. This demonstrates the difference between a path of mapped straight lines and actual traverses while conducting field geology. Straight-line segments drawn over our actual traverse path in GoogleEarth show a total distance of only 6.7 km, a margin of approximately 25%. The main points for this exercise were to show the engineers that real-time flexibility must be preserved, and that a distance buffer must be anticipated. Short duration science mission scenarios focus on distance traveled and diversity of sites visited. Long duration outpost missions might enable thorough analyses of features. For our sites we show a buildup of traverses based on our evolving hypotheses. The main points for this exercise were to show the engineers that significant science questions are rarely answered with one visit per feature. In other words, science success is not determined by checking matrices boxes when field geologists walk on mapped lines and visit points of interest. The quality of work conducted during those walks and visits is what determines science success, often requiring long or multiple visits.

Since the development of electron microprobe over forty years ago, they have become an indispensable instrument for analytical investigations in the areas of metallurgy, mineralogy, chemistry, and biology. Our comparisons focus on data generated using the JEOL JXA 8530F housed in the Southeastern North Carolina Regional Microanalytical and Imaging Center (SENCR-MIC) with analyses of the same samples performed in other laboratories with tungsten filament electron microprobes. Current results indicate similar detection limits prevail. However, the advances in spatial resolution in terms of imaging and points of data generation allow for much refined assessments of micron-scale phase differences. Optimum analytical areas can be obtained at low accelerating voltages. A field emission microprobe can maintain a very small electron beam spot size even at low accelerating voltages, and, therefore, can take advantage to the greatly reduced interaction volumes obtained under these conditions. The smallest analytical areas are obtained at around 6-7 kV, for typical silicates, resulting in an analytical area of only a couple hundred nanometers.

Students are challenged to explore, understand, and resolve an issue individually and/or in groups. They are provided with background information and guidance to resources on the web in order to adequately address their issue. WebQuests engage students, increase their factual and conceptual knowledge of a given topic, and improve their critical use of the Internet. WebQuests and other similar web-based educational activities are growing more common as teachers make an effort to take advantage of the technology increasingly available both at school and at home. While WebQuests have been around since the mid 1990's, the "web 2.0" era of social media provides many new opportunities to promote understanding through dialogue. Our team has produced the first in a three-part WebQuest series (found at www.complex-life.org) centered around the Ediacaran and the organisms that lived in the world's seas during this time period. These WebQuests are distinguished because: 1) we have added novel content, including graphics and extensive video clips, to complement pre-existing web resources; 2) we have worked with research scientists in the development of the WebQuest from concept to content to ensure that the data in the activity is accurate, up to date, and exciting; 3) we incorporate varied content and "web 2.0" capabilities in the WebQuest including video, Google Earth, screen casting, customized Google search bars, surveys, and a wiki-style glossary page; 4) we encourage students to upload their WebQuest projects to the web and share them with others inside and outside their classroom. Our approach has many pedagogical benefits including increasing critical thinking skills, learning how to apply acquired knowledge, determining the validity of web-based information, and engaging in the process of communicating scientific ideas to others. WebQuests are a flexible, powerful, yet under-utilized means in which scientists and educators can collaborate to create innovative online content to excite and inspire the next generation.

The fragments were separately collected as individual stones from the meteorite's linear strewn field in the Nubian Desert. Each of the fragments represents a sample of a different and distinct portion of asteroid 2008 TC (sub 3) . Ten of the fragments span the same range of values of delta (super 18) O, delta (super 17) O, and Delta (super 17) O, and follow the same trend along the carbonaceous chondrite anhydrous minerals (CCAM) line as monomict and polymict members of the ureilite family of meteorites. The oxygen isotope composition of fragment #25 is consistent with its resemblance petrographically to an H5 ordinary chondrite. Our results demonstrate that a single small asteroidal parent body, asteroid 2008 TC (sub 3) , only 4 m in length, encompassed the entire range of variation in oxygen isotope compositions measured for monomict and polymict ureilites.

LC-FD/ToF-MS analyses of hot-water extracts from the meteorite revealed a complex distribution of two- to seven-carbon aliphatic amino acids and one- to three-carbon amines with abundances ranging from 0.5 to 149 parts-per-billion (ppb). The enantiomeric ratios of the amino acids alanine, beta -amino-n-butyric acid, 2-amino-2-methylbutanoic acid (isovaline), and 2-aminopentanoic acid (norvaline) in the meteorite were racemic (D/L approximately 1), indicating that these amino acids are indigenous to the meteorite and not terrestrial contaminants. Several other nonprotein amino acids were also identified in the meteorite above background levels including alpha -aminoisobutyric acid (alpha -AIB), 4-amino-2-methylbutanoic acid, 4-amino-3-methylbutanoic acid, and 3-, 4-, and 5-aminopentanoic acid. The total abundances of isovaline and alpha -AIB in Almahata Sitta are approximately 1000 times lower than the abundances of these amino acids found in the CM carbonaceous chondrite Murchison. The extremely low abundances and unusual distribution of five-carbon amino acids in Almahata Sitta compared to CI, CM, and CR carbonaceous chondrites may reflect extensive thermal alteration of amino acids on the parent asteroid by partial melting during formation or subsequent impact shock heating. It is also possible that amino acids were synthesized by catalytic reactions on the parent body after asteroid 2008 TC3 cooled to lower temperatures, or introduced as a contaminant from unrelated meteorite clasts and chemically altered by alpha -decarboxylation.

Across this spectral range, ureilite spectra are characterized by a steep rise in reflectance over the 0.3 to approximately 0.7 mu m range, low overall reflectance (<25%) and weak mafic iron silicate absorption bands in the 1 and 2 mu m region. The weakness of these bands and the low reflectance are attributed to the presence of dispersed graphite and related carbonaceous phases, metal, and possibly shock. Wavelength positions of the mafic silicate absorption bands span a range of values, but are consistent with the presence of pyroxene and olivine. Ureilite spectra generally exhibit blue slopes across the 0.7-2.6 mu m interval and exhibit many overall similarities to some carbonaceous chondrites. The weak features and spectral diversity of ureilites make reflectance spectroscopy-based identification of a ureilite parent body challenging. As terrestrial alteration of ureilites is prevalent, spectral studies of falls are most useful for determining the spectral properties of likely parent bodies.

The main lithologies are (1) a pyroxene-dominated, very porous, highly reduced lithology, (2) a pyroxene-dominated compact lithology, and (3) an olivine-dominated compact lithology. Although it seems possible that all three lithologies grade smoothly into each other at the kg-scale, at the g-scale this is not apparent. The meteorite is a polymict ureilite, with some intriguing features including exceptionally variable porosity and pyroxene composition. Although augite is locally present in Almahata Sitta, it is a minor phase in most (but not all) samples we have observed. Low-calcium pyroxene (<5 mole% wollastonite) is more abundant than compositionally defined pigeonite; however, we found that even the low-Ca pyroxene in Almahata Sitta has the monoclinic pigeonite crystal structure, and thus is properly termed pigeonite. As the major pyroxene in Almahata Sitta is pigeonite, and the abundance of pigeonite is generally greater than that of olivine, this meteorite might be called a pigeonite-olivine ureilite, rather than the conventional olivine-pigeonite ureilite group. The wide variability of lithologies in Almahata Sitta reveals a complex history, including asteroidal igneous crystallization, impact disruption, reheating and partial vaporization, high-temperature reduction and carbon burning, and re-agglomeration.

An investigation is made into what is known about asteroids with roughly the same spectroscopic signature as 2008 TC (sub 3) . A population of low-inclination near-Earth asteroids is identified with spectra similar to 2008 TC3. Five asteroid families in the Main Belt, as well as a population of ungrouped asteroids scattered in the inner and central belts, are identified as possible source regions for this near-Earth population and 2008 TC (sub 3) . Three of the families are ruled out on dynamical and spectroscopic grounds. New near-infrared spectra of 142 Polana and 1726 Hoffmeister, lead objects in the two other families, also show a poor match to Almahata Sitta. Thus, there are no Main Belt spectral analogs to Almahata Sitta currently known. Space weathering effects on ureilitic materials have not been investigated, so that it is unclear how the spectrum of the Main Belt progenitor may look different from the spectra of 2008 TC (sub 3) and the Almahata Sitta meteorites. Dynamical arguments are discussed, as well as ureilite petrogenesis and parent body evolution models, but these considerations do not conclusively point to a source region either, other than that 2008 TC (sub 3) probably originated in the inner asteroid belt.

A preliminary analysis of one of these stones (#7) showed it to be a unique polymict ureilite (Jenniskens et al. 2009). Here we report 39 mid-infrared (mid-IR) (4000-450 cm (super -1) ; 2.5-22.2 mu m) transmission spectra taken from 26 different stones collected from the strewn field. The ureilite spectra show a number of absorption bands including a complex feature centered near 1000 cm (super -1) (10 mu m) due to Si-O stretching vibrations. The profiles of the silicate features fall along a mixing line with endmembers represented by Mg-rich olivines and pyroxenes, and no evidence is seen for the presence of phyllosilicates. The relative abundances of olivine and pyroxene show substantial variation from sample to sample and sometimes differ between multiple samples taken from the same stone. Analysis of a mass normalized coaddition of all our ureilite spectra yields an olivine-to-pyroxene ratio of 74:26, a value that falls in the middle of the range inferred from the infrared spectra of other ureilites. Both the predominance of olivine and the variable olivine-to-pyroxene ratio are consistent with the known composition and heterogeneity of other ureilites. Variations in the colors of the samples and the intensities of the silicate feature relative to the mass of the samples indicate a significant contribution from additional materials having no strong absorption bands, most likely graphitized carbon, diamonds, and/or metals.

The pyroxenes (mg# = approximately 0.92) are present as minute individual grains (10-20 mu m in size) showing a polycrystalline texture, and they are both low-Ca and high-Ca pyroxenes. Although their Ca contents are as low as Wo (sub 2-3) , the EBSD analysis shows that low-Ca pyroxenes are clinopyroxene (P2 (sub 1) /c). The obtained pyroxene equilibration temperature (1240-1280 degrees C) is consistent with the previous studies on many ureilites. In low-Ca pigeonite, (001) augite exsolution lamellae (10-15 nm wide) develop in the pigeonite host (20-45 nm wide), and a similar exsolution texture was observed in augite. The exsolution wavelength of pyroxene (typically 30-60 nm) gives the cooling rate of 0.2-5 degrees C h (super -1) . Such a rapid cooling probably records quenching from high temperature (1240-1280 degrees C) down to 1000 degrees C (estimated from the exsolution pair) due to the breakup of the ureilite parent body (UPB) while it was still hot. The pyroxene microstructure of Almahata Sitta is within the range of known ureilites and is most similar to that of Allan Hills (ALH) A81101 with the affinity of polycrystalline texture. The coarser exsolution texture of ALHA81101 pyroxene suggests slower cooling history than Almahata Sitta. However, direct comparison is difficult because of different pyroxene compositions. Because ALHA77257 has a similar pyroxene composition to Almahata Sitta and does not show visible pyroxene exsolution, it should have cooled faster than Almahata Sitta. Rapid, albeit variable cooling rates observed in different ureilite samples may suggest that they originated from UPB fragments of different size.

From thermal events recorded in the mineralogy, petrology, and chemistry of ureilites recovered from the fall area, we reconstruct a timeline of events that led to their genesis. This history is similar to that of other known ureilites and supportive of a disrupted ureilite parent body hypothesis. Temperatures of final mantle equilibrium were 1200-1300 degrees C, but this high-temperature history was abruptly terminated by rapid cooling and reduction associated with pressure loss. The onset of late reduction reactions and onset of rapid cooling must have been essentially simultaneous, most likely engendered by the same event. Cooling rates of 0.05-2 degrees C h-1 determined from reversely zoned olivines and pyroxenes in Almahata Sitta imply rapid disassembly into fragments tens meters in size or smaller. This phenomenon seems to have affected all known portions of the ureilite parent body mantle, implying an event of global significance rather than localized unroofing. Reaccretion of one or more daughter asteroids occurred only after significant heat loss at minimum time scales of weeks to months, during which time the debris cloud surrounding the disrupted parent was inefficient at retaining heat.

Each organization likely operates with a separate data platform, perhaps in response to different data sets, and responds to a different user community, whether internal, the scientific community, or the public. Apart from the technical challenges of data integration, the conceptual challenges of building a single database to respond to multiple agency and constituency agendas can be the greatest obstacle. We illustrate these challenges by examining the samples and data held collectively by the U.S. Antarctic Meteorite Program, a joint venture of NSF, NASA and the Smithsonian Institution. NSF is responsible for the collection of Antarctic meteorites through a grant to CWRU. Field photographs of each meteorite are not databased, while field locales are mapped using ArcGIS. The ArcGIS mapping project primarily benefits field expeditions, allowing quick visualization of productive field locales to plan future expeditions, and meteorite classifiers, allowing visualization of potential pairing groups. NASA is responsible for short-term curation of Antarctic meteorites at Johnson Space Center. In addition to specimens, JSC holds data on current samples and allocation histories in a FoxPro database primarily for use by curators and an allocation committee. JSC also hosts a web-based search engine on the current availability of samples and meteorite descriptions. This database, although publicly accessible, is primarily used by the scientific community. The Smithsonian is responsible for classification and long-term curation. In addition to specimens, data is held in EMu with a subset available through a web-based search engine. EMu, a relational database primarily used internally by museums, is designed to integrate collections information across disciplines. As such, it is not tailored to the geologic community and the primary audience for the search engine is the public, not the scientific community. Although long-term integration of Antarctic meteorite data is desirable, it presents both a logistical challenge and, more importantly, a distinct set of audiences which no single database structure is likely to satisfy.

AN - 873133668; 14697-7_0013 AB - PURPOSE: A shoreline restoration program with a 50-year planning horizon to reduce storm-induced physical damage at Wallops Flight Facility (WFF) on Wallops Island, Virginia is proposed. WFF is a National Aeronautics and Space Administration (NASA) facility under management of the Goddard Space Flight Center and has multiple tenants, including the Navy, Coast Guard, Mid-Atlantic Regional Spaceport (MARS), and the National Oceanic and Atmospheric Administration. The facility is a fully capable launch range for rockets and scientific balloons, and includes a research airport. The WFF is located in the northeastern portion of Accomack County on the Delmarva Peninsula, and is comprised of the main base, Wallops mainland, and Wallops Island. Wallops Island, which is seven miles long and 2,650 feet wide, is bounded by the Chincoteague Inlet to the north, the Assawoman Inlet to the south, the Atlantic Ocean to the east, and estuaries to the west. Wallops Island has experienced shoreline changes throughout the six decades that NASA has occupied the site and the existing seawall is being undermined because there is little or no protective sand beach remaining and storm waves break directly on the rocks. Three action alternatives and a No Action Alternative are evaluated in this final EIS. Alternative 1, which is the preferred alternative, would involve initial construction to extend Wallops Island's existing rock seawall a maximum of 4,600 feet south of its southernmost point and placement of sand dredged from an offshore shoal on the Wallops Island shoreline. A total of nine follow-on renourishment cycles would occur every 5 years. The initial fill plus the total fill volume over nine renourishment events would result in approximately 10.5 million cubic yards of sand being placed on the shoreline. Under Alternative 2, the seawall extension would be the same as described for Alternative 1, but a 430-foot rock groin would be added at the south end of the Wallops Island shoreline. Alternative 3 would also include the seawall extension and, in addition, a single 300-foot long breakwater would be constructed 750 feet offshore at the south end of the Wallops Island shoreline. Alternatives 2 and 3 would result in more sand being retained along the Wallops Island beach, so less fill would be required for both the initial nourishment and renourishment. However, an increase in erosion south of the structures could occur. POSITIVE IMPACTS: Implementation would ensure the continued ability of NASA, the Navy, and MARS to serve the nation's rapidly growing civil, defense, academic, and commercial aerospace requirements by reducing the potential for damage to, or loss of, over $1 billion in existing assets from wave impacts associated with storm events. NEGATIVE IMPACTS: Dredging in the offshore shoals and sand placement in the nearshore environment would elevate turbidity in marine waters. Approximately 1,280 acres of benthic habitat would be removed during dredging for the initial beach fill; and placement of the initial fill would bury 1.2 acres of hard-bottom intertidal habitat and 22.5 acres of subtidal benthic community along the existing seawall. Each of nine proposed beach renourishment cycles would adversely impact an additional 347 acres of benthic habitat. Disturbance and noise could affect marine mammals, loggerhead sea turtle, and piping plover.

AN - 873133661; 14697-7_0010 AB - PURPOSE: A shoreline restoration program with a 50-year planning horizon to reduce storm-induced physical damage at Wallops Flight Facility (WFF) on Wallops Island, Virginia is proposed. WFF is a National Aeronautics and Space Administration (NASA) facility under management of the Goddard Space Flight Center and has multiple tenants, including the Navy, Coast Guard, Mid-Atlantic Regional Spaceport (MARS), and the National Oceanic and Atmospheric Administration. The facility is a fully capable launch range for rockets and scientific balloons, and includes a research airport. The WFF is located in the northeastern portion of Accomack County on the Delmarva Peninsula, and is comprised of the main base, Wallops mainland, and Wallops Island. Wallops Island, which is seven miles long and 2,650 feet wide, is bounded by the Chincoteague Inlet to the north, the Assawoman Inlet to the south, the Atlantic Ocean to the east, and estuaries to the west. Wallops Island has experienced shoreline changes throughout the six decades that NASA has occupied the site and the existing seawall is being undermined because there is little or no protective sand beach remaining and storm waves break directly on the rocks. Three action alternatives and a No Action Alternative are evaluated in this final EIS. Alternative 1, which is the preferred alternative, would involve initial construction to extend Wallops Island's existing rock seawall a maximum of 4,600 feet south of its southernmost point and placement of sand dredged from an offshore shoal on the Wallops Island shoreline. A total of nine follow-on renourishment cycles would occur every 5 years. The initial fill plus the total fill volume over nine renourishment events would result in approximately 10.5 million cubic yards of sand being placed on the shoreline. Under Alternative 2, the seawall extension would be the same as described for Alternative 1, but a 430-foot rock groin would be added at the south end of the Wallops Island shoreline. Alternative 3 would also include the seawall extension and, in addition, a single 300-foot long breakwater would be constructed 750 feet offshore at the south end of the Wallops Island shoreline. Alternatives 2 and 3 would result in more sand being retained along the Wallops Island beach, so less fill would be required for both the initial nourishment and renourishment. However, an increase in erosion south of the structures could occur. POSITIVE IMPACTS: Implementation would ensure the continued ability of NASA, the Navy, and MARS to serve the nation's rapidly growing civil, defense, academic, and commercial aerospace requirements by reducing the potential for damage to, or loss of, over $1 billion in existing assets from wave impacts associated with storm events. NEGATIVE IMPACTS: Dredging in the offshore shoals and sand placement in the nearshore environment would elevate turbidity in marine waters. Approximately 1,280 acres of benthic habitat would be removed during dredging for the initial beach fill; and placement of the initial fill would bury 1.2 acres of hard-bottom intertidal habitat and 22.5 acres of subtidal benthic community along the existing seawall. Each of nine proposed beach renourishment cycles would adversely impact an additional 347 acres of benthic habitat. Disturbance and noise could affect marine mammals, loggerhead sea turtle, and piping plover.

AN - 873133335; 14697-7_0014 AB - PURPOSE: A shoreline restoration program with a 50-year planning horizon to reduce storm-induced physical damage at Wallops Flight Facility (WFF) on Wallops Island, Virginia is proposed. WFF is a National Aeronautics and Space Administration (NASA) facility under management of the Goddard Space Flight Center and has multiple tenants, including the Navy, Coast Guard, Mid-Atlantic Regional Spaceport (MARS), and the National Oceanic and Atmospheric Administration. The facility is a fully capable launch range for rockets and scientific balloons, and includes a research airport. The WFF is located in the northeastern portion of Accomack County on the Delmarva Peninsula, and is comprised of the main base, Wallops mainland, and Wallops Island. Wallops Island, which is seven miles long and 2,650 feet wide, is bounded by the Chincoteague Inlet to the north, the Assawoman Inlet to the south, the Atlantic Ocean to the east, and estuaries to the west. Wallops Island has experienced shoreline changes throughout the six decades that NASA has occupied the site and the existing seawall is being undermined because there is little or no protective sand beach remaining and storm waves break directly on the rocks. Three action alternatives and a No Action Alternative are evaluated in this final EIS. Alternative 1, which is the preferred alternative, would involve initial construction to extend Wallops Island's existing rock seawall a maximum of 4,600 feet south of its southernmost point and placement of sand dredged from an offshore shoal on the Wallops Island shoreline. A total of nine follow-on renourishment cycles would occur every 5 years. The initial fill plus the total fill volume over nine renourishment events would result in approximately 10.5 million cubic yards of sand being placed on the shoreline. Under Alternative 2, the seawall extension would be the same as described for Alternative 1, but a 430-foot rock groin would be added at the south end of the Wallops Island shoreline. Alternative 3 would also include the seawall extension and, in addition, a single 300-foot long breakwater would be constructed 750 feet offshore at the south end of the Wallops Island shoreline. Alternatives 2 and 3 would result in more sand being retained along the Wallops Island beach, so less fill would be required for both the initial nourishment and renourishment. However, an increase in erosion south of the structures could occur. POSITIVE IMPACTS: Implementation would ensure the continued ability of NASA, the Navy, and MARS to serve the nation's rapidly growing civil, defense, academic, and commercial aerospace requirements by reducing the potential for damage to, or loss of, over $1 billion in existing assets from wave impacts associated with storm events. NEGATIVE IMPACTS: Dredging in the offshore shoals and sand placement in the nearshore environment would elevate turbidity in marine waters. Approximately 1,280 acres of benthic habitat would be removed during dredging for the initial beach fill; and placement of the initial fill would bury 1.2 acres of hard-bottom intertidal habitat and 22.5 acres of subtidal benthic community along the existing seawall. Each of nine proposed beach renourishment cycles would adversely impact an additional 347 acres of benthic habitat. Disturbance and noise could affect marine mammals, loggerhead sea turtle, and piping plover.

[Part 4 of 14] T2 - WALLOPS FLIGHT FACILITY SHORELINE RESTORATION AND INFRASTRUCTURE PROTECTION PROGRAM, WALLOPS ISLAND, VIRGINIA. AN - 873132012; 14697-7_0004 AB - PURPOSE: A shoreline restoration program with a 50-year planning horizon to reduce storm-induced physical damage at Wallops Flight Facility (WFF) on Wallops Island, Virginia is proposed. WFF is a National Aeronautics and Space Administration (NASA) facility under management of the Goddard Space Flight Center and has multiple tenants, including the Navy, Coast Guard, Mid-Atlantic Regional Spaceport (MARS), and the National Oceanic and Atmospheric Administration. The facility is a fully capable launch range for rockets and scientific balloons, and includes a research airport. The WFF is located in the northeastern portion of Accomack County on the Delmarva Peninsula, and is comprised of the main base, Wallops mainland, and Wallops Island. Wallops Island, which is seven miles long and 2,650 feet wide, is bounded by the Chincoteague Inlet to the north, the Assawoman Inlet to the south, the Atlantic Ocean to the east, and estuaries to the west. Wallops Island has experienced shoreline changes throughout the six decades that NASA has occupied the site and the existing seawall is being undermined because there is little or no protective sand beach remaining and storm waves break directly on the rocks. Three action alternatives and a No Action Alternative are evaluated in this final EIS. Alternative 1, which is the preferred alternative, would involve initial construction to extend Wallops Island's existing rock seawall a maximum of 4,600 feet south of its southernmost point and placement of sand dredged from an offshore shoal on the Wallops Island shoreline. A total of nine follow-on renourishment cycles would occur every 5 years. The initial fill plus the total fill volume over nine renourishment events would result in approximately 10.5 million cubic yards of sand being placed on the shoreline. Under Alternative 2, the seawall extension would be the same as described for Alternative 1, but a 430-foot rock groin would be added at the south end of the Wallops Island shoreline. Alternative 3 would also include the seawall extension and, in addition, a single 300-foot long breakwater would be constructed 750 feet offshore at the south end of the Wallops Island shoreline. Alternatives 2 and 3 would result in more sand being retained along the Wallops Island beach, so less fill would be required for both the initial nourishment and renourishment. However, an increase in erosion south of the structures could occur. POSITIVE IMPACTS: Implementation would ensure the continued ability of NASA, the Navy, and MARS to serve the nation's rapidly growing civil, defense, academic, and commercial aerospace requirements by reducing the potential for damage to, or loss of, over $1 billion in existing assets from wave impacts associated with storm events. NEGATIVE IMPACTS: Dredging in the offshore shoals and sand placement in the nearshore environment would elevate turbidity in marine waters. Approximately 1,280 acres of benthic habitat would be removed during dredging for the initial beach fill; and placement of the initial fill would bury 1.2 acres of hard-bottom intertidal habitat and 22.5 acres of subtidal benthic community along the existing seawall. Each of nine proposed beach renourishment cycles would adversely impact an additional 347 acres of benthic habitat. Disturbance and noise could affect marine mammals, loggerhead sea turtle, and piping plover.

During the half-century history of x-ray astronomy, the sensitivity of focusing x-ray telescopes-through finer angular resolution and increased effective area-has improved by a factor of a 100 million. This technological advance has enabled numerous exciting discoveries and increasingly detailed study of the high-energy universe-including accreting (stellarmass and super-massive) black holes, accreting and isolated neutron stars, pulsar-wind nebulae, shocked plasma in supernova remnants, and hot thermal plasma in clusters of galaxies. As the largest structures in the universe, galaxy clusters constitute a unique laboratory for measuring the gravitational effects of dark matter and of dark energy. Here, we review the history of high-resolution x-ray telescopes and highlight some of the scientific results enabled by these telescopes. Next, we describe the planned next-generation x-ray-astronomy facility-the International X-ray Observatory (IXO). We conclude with an overview of a concept for the next next-generation facility-Generation X. The scientific objectives of such a mission will require very large areas (about 10000 m super(2)) of highly-nested lightweight grazing-incidence mirrors with exceptional (about 0.1-arcsecond) angular resolution. Achieving this angular resolution with lightweight mirrors will likely require on-orbit adjustment of alignment and figure.

These spectra show the changes as naphthalene clustering and aggregation occurs, with moderate spectral shifts affecting the C-H vibrational modes and relatively small or no shifts to the C-C and C-C-C vibrational modes. The possible contribution of homogeneous naphthalene clusters to the interstellar unidentified infrared bands is discussed. The contribution of polycyclic aromatic hydrocarbon (PAH) clusters to the 7.7 mu m emission plateau and the blue shading of the 12.7 mu m emission band are identified as promising candidates for future research. In addition, since PAH clusters are model components of Jupiter and Titan's atmospheres, the information presented here may also be applicable to the spectroscopy of these objects.

This is because CO2, like ozone, N2O, CH4, and chlorofluorocarbons, does not condense and precipitate from the atmosphere at current climate temperatures, whereas water vapor can and does. Noncondensing greenhouse gases, which account for 25% of the total terrestrial greenhouse effect, thus serve to provide the stable temperature structure that sustains the current levels of atmospheric water vapor and clouds via feedback processes that account for the remaining 75% of the greenhouse effect. Without the radiative forcing supplied by CO2 and the other noncondensing greenhouse gases, the terrestrial greenhouse would collapse, plunging the global climate into an icebound Earth state.

Marine geophysical products from MODIS-Aqua depend on the efficacy of the atmospheric correction process, which can be problematic in coastal environments. The operational atmospheric correction algorithm for MODIS-Aqua requires an assumption of negligible near-infrared water-leaving radiance, nL w(NIR). This assumption progressively degrades with increasing turbidity and, as such, methods exist to account for non-negligible nL w(NIR) within the atmospheric correction process or to use alternate radiometric bands where the assumption is satisfied, such as those positioned within shortwave infrared (SWIR) region of the spectrum. We evaluated a decade-long time-series of nL w(I') from MODIS-Aqua in Chesapeake Bay derived using NIR and SWIR bands for atmospheric correction. Low signal-to-noise ratios (SNR) for the SWIR bands of MODIS-Aqua added noise errors to the derived radiances, which produced broad, flat frequency distributions of nL w(I') relative to those produced using the NIR bands. The SWIR approach produced an increased number of negative nL w(I') and decreased sample size relative to the NIR approach. Revised vicarious calibration and regional tuning of the scheme to switch between the NIR and SWIR approaches may improve retrievals in Chesapeake Bay, however, poor SNR values for the MODIS-Aqua SWIR bands remain the primary deficiency of the SWIR-based atmospheric correction approach.

Analysis of changes in phenology can provide quantitative information on the effect of climate variability on growing seasons in agricultural regions. Using a robust statistical methodology, we describe the relationship between phenology metrics derived from the 26year AVHRR NDVI record and the North Atlantic Oscillation index (NAO), the Indian Ocean Dipole (IOD), the Pacific Decadal Oscillation (PDO), and the Multivariate ENSO Index (MEI). We map the most significant positive and negative correlation for the four climate indices in Eastern, Western and Southern Africa between two phenological metrics and the climate indices. Our objective is to provide evidence of whether climate variability captured in the four indices has had a significant impact on the vegetative productivity of Africa during the past quarter century. We found that the start of season and cumulative NDVI were significantly affected by large scale variations in climate. The particular climate index and the timing showing highest correlation depended heavily on the region examined. In Western Africa the cumulative NDVI correlates with PDO in September-November. In Eastern Africa the start of the June-October season strongly correlates with PDO in March-May, while the PDO in December-February correlates with the start of the February-June season. The cumulative NDVI over this last season relates to the MEI of March-May. For Southern Africa, high correlations exist between SOS and NAO of September-November, and cumulative NDVI and MEI of March-May. The research shows that climate indices can be used to anticipate late start and variable vigor in the growing season of sensitive agricultural regions in Africa.

Over the past 50 years, NASA has been the world leader in developing space-based Earth observing systems and capabilities that have fundamentally changed our view of our planet and have defined Earth system science. The U.S. National Research Council report "Earth Observations from Space: The First 50 Years of Scientific Achievements" published in 2008 by the National Academy of Sciences articulates those key achievements and the evolution of the space observing capabilities, looking forward to growing potential to address Earth science questions and enable an abundance of practical applications. NASA's Earth science program is an end-to-end one that encompasses the development of observational techniques and the instrument technology needed to implement them. This includes laboratory testing and demonstration from surface, airborne, or space-based platforms; research to increase basic process knowledge; incorporation of results into complex computational models to more fully characterize the present state and future evolution of the Earth system; and development of partnerships with national and international organizations that can use the generated information in environmental forecasting and in policy, business, and management decisions. Currently, NASA's Earth Science Division (ESD) has 14 operating Earth science space missions with 6 in development and 18 under study or in technology risk reduction. Two Tier 2 Decadal Survey climate-focused missions, Active Sensing of CO2 Emissions over Nights, Days and Seasons (ASCENDS) and Surface Water and Ocean Topography (SWOT), have been identified in conjunction with the U.S. Global Change Research Program and initiated for launch in the 2019-2020 timeframe. NASA will begin refurbishment of the SAGE III atmospheric chemistry instrument to be hosted by the International Space Station (ISS) as early as 2013 and will initiate a Gravity Recovery and Climate Experiment (GRACE) Follow-on mission for launch in 2016.

The CLARREO mission accomplishes this critical objective through rigorous SI traceable decadal change observations that will reduce the key uncertainties in current climate model projections. These same uncertainties also lead to uncertainty in attribution of climate change to anthropogenic forcing. CLARREO will make highly accurate and SI-traceable global, decadal change observations sensitive to the most critical, but least understood climate forcing, responses, and feedbacks. The CLARREO breakthrough is to achieve the required levels of accuracy and traceability to SI standards for a set of observations sensitive to a wide range of key decadal change variables. The required accuracy levels are determined so that climate trend signals can be detected against a background of naturally occurring variability. The accuracy for decadal change traceability to SI standards includes uncertainties associated with instrument calibration, satellite orbit sampling, and analysis methods. Unlike most space missions, the CLARREO requirements are driven not by the instantaneous accuracy of the measurements, but by accuracy in the large time/space scale averages that are necessary to understand global, decadal climate changes.

Such improvements will in turn improve decision support systems in broad societal applications (e.g. water resource management, agriculture, transportation, etc). GPM is a partnership between NASA and the Japan Aerospace Exploration Agency (JAXA), building upon their highly successful partnership on the Tropical Rainfall Measuring Mission (TRMM). The GPM architecture consists of NASA satellites operating in partnership with other earth-observing satellites and instruments to produce global precipitation science data. The current generation of multi-satellite global precipitation products based on microwave/infrared sensors from uncoordinated satellite missions has for its anchor the TRMM precipitation radar and the TRMM Microwave Imager measurements over the tropics and subtropics (+/- 35 degrees latitude), with a mean sampling time of approximately 17 hours. The GPM mission will deploy a spaceborne Core Observatory as a reference standard to unify a space constellation of research and operational microwave sensors aimed at providing uniformly calibrated precipitation measurements globally every 2-4 hours. The Core Observatory measurements will provide, for the first time, quantitative information on precipitation particle size distribution needed for improving the accuracy of precipitation estimates by microwave radiometers and radars. In addition, the GPM will also include a second microwave radiometer and a Tracking and Data Relay Satellite (TDRS) communications subsystem for near real time data relay for a future partner-provided constellation satellite. This second GPM Microwave Imager (GMI) instrument, flown in a low-inclination orbit, combined with the Core Observatory will provide an improvement over TRMM in both global coverage and sampling rate (+/- 65 degrees, 10 hour mean sampling time). GPM is well into its final design and fabrication (Phase C) with planned launches in 2013 and 2014.

The grain opacities in the envelope of the protoplanet are computed using a detailed model that includes settling and coagulation of grains and that incorporates a recalculation of the grain size distribution at each point in time and space. We generally find lower opacities than the 2% of interstellar values used in previous calculations (Hubickyj, O., Bodenheimer, P., Lissauer, J.J. [2005]. Icarus 179, 415-431; Lissauer, J.J., Hubickyj, O., D'Angelo, G., Bodenheimer, P. [2009]. Icarus 199, 338-350). These lower opacities result in more rapid heat loss from and more rapid contraction of the protoplanetary envelope. For a given surface density of solids, the new calculations result in a substantial speedup in formation time as compared with those previous calculations. Formation times are calculated to be 1.0, 1.9, and 4.0 Myr, and solid core masses are found to be 16.8, 8.9, and 4.7 M (super circled plus) , for solid surface densities, sigma , of 10, 6, and 4 g cm (super -2) , respectively. For sigma = 10 and sigma = 6 g cm (super -2) , respectively, these formation times are reduced by more than 50% and more than 80% compared with those in a previously published calculation with the old approximation to the opacity.

AN - 861984617; 2011-034081 AB - We have developed a numerical model for assessing the lifetime of ice deposits in martian caves that are open to the atmosphere. Our model results and sensitivity tests indicate that cave ice would be stable over significant portions of the surface of Mars. Ice caves on Earth commonly occur in lava tubes, and Mars has been significantly resurfaced by volcanic activity during its history, including the two main volcanic provinces, the Tharsis and Elysium rises. These areas, known or suspected of having subsurface caves and related voids are among the most favorable regions for the occurrence of ice stability. The martian ice cave model predicts regions which, if caves occur, would potentially be areas of astrobiological importance as well as possible water sources for future human missions to Mars.

First, we compare colors R(0.673 mu m)/R(0.953 mu m) and R(0.673 mu m)/R(1.042 mu m) of Vesta's units with those of V-type asteroids (vestoids) as well as howardite, eucrite, and diogenite meteorites (HEDs). This comparative analysis showed that: (i) on the color-color plot, regions on Vesta are clustered whereas vestoids and HEDs cover a wide range in color; (ii) very few vestoids or HEDs fall into Vesta's color region. This implies that Vesta's units are more homogenous than most vestoids and HEDs examined here and material of the units are slightly different from that of vestoids and HEDs. Assuming reasonable choice of end-member materials, an optical model (Shkuratov et al., 1999) was used to simulate intimate mixtures of particles at the surface of Vesta's units. Simulation of albedo, colors, and four-point spectra of Vesta's units reveals that the rock-forming material is nearly equal for all units and has HED-like composition. Diversity of the units depends on the minor constituents such as chromite and a neutral phase. The western units contain more chromite and neutral phase than the eastern, consequently albedo of the western units is lower and their four-point spectra are flatter. Olivine and feldspar are also needed to give the best fit for the calculated and observed albedos and colors of Vesta's units, but being in minor amount in Vesta's rocks they play a secondary role in contributing to the optical properties of the units. Questions about the proportions of HED-like rock and the constituent called neutral phase remain open. Spectrophotometric studies of Vesta with both higher spatial and spectral resolution as expected from NASA's Dawn mission are needed for resolving these problems.

The Lunar Crater Observation and Sensing Satellite (LCROSS) mission was designed to detect hydrogen-bearing volatiles directly. Neutron flux measurements of the Moon's south polar region from the Lunar Exploration Neutron Detector (LEND) on the Lunar Reconnaissance Orbiter (LRO) spacecraft were used to select the optimal impact site for LCROSS. LEND data show several regions where the epithermal neutron flux from the surface is suppressed, which is indicative of enhanced hydrogen content. These regions are not spatially coincident with permanently shadowed regions of the Moon. The LCROSS impact site inside the Cabeus crater demonstrates the highest hydrogen concentration in the lunar south polar region, corresponding to an estimated content of 0.5 to 4.0% water ice by weight, depending on the thickness of any overlying dry regolith layer. The distribution of hydrogen across the region is consistent with buried water ice from cometary impacts, hydrogen implantation from the solar wind, and/or other as yet unknown sources.

The Lunar Crater Observation and Sensing Satellite (LCROSS) struck one of the coldest of these regions, where subsurface temperatures are estimated to be 38 kelvin. Large areas of the lunar polar regions are currently cold enough to cold-trap water ice as well as a range of both more volatile and less volatile species. The diverse mixture of water and high-volatility compounds detected in the LCROSS ejecta plume is strong evidence for the impact delivery and cold-trapping of volatiles derived from primitive outer solar system bodies.

The Lyman Alpha Mapping Project (LAMP) ultraviolet spectrograph onboard the Lunar Reconnaissance Orbiter (LRO) observed the plume generated by the LCROSS impact as far-ultraviolet emissions from the fluorescence of sunlight by molecular hydrogen and carbon monoxide, plus resonantly scattered sunlight from atomic mercury, with contributions from calcium and magnesium. The observed light curve is well simulated by the expansion of a vapor cloud at a temperature of approximately 1000 kelvin, containing approximately 570 kilograms (kg) of carbon monoxide, approximately 140 kg of molecular hydrogen, approximately 160 kg of calcium, approximately 120 kg of mercury, and approximately 40 kg of magnesium.

The periodic occurrence times of events from individual clusters are clearly related to tidal stress, but also exhibit departures from the temporal regularity this relationship would seem to imply. Even simplified models that capture some of the relevant physics require a large number of variables. However, a single, easily accessible variable--the time interval I(n) between events--can be used to reveal behavior not readily observed using typical periodicity analyses (e.g., Fourier analyses). The delay-coordinate (DC) map, a particularly revealing way to display data from a time series, is a map of successive intervals: I(n+1) plotted vs. I(n). We use a DC approach to characterize the dynamics of moonquake occurrence. Moonquake-like DC maps can be reproduced by combining sequences of synthetic events that occur with variable probability at tidal periods. Though this model gives a good description of what happens, it has little physical content, thus providing only little insight into why moonquakes occur. We investigate a more mechanistic model. In this study, we present a series of simple models of deep moonquake occurrence, with consideration of both tidal stress and stress drop during events. We first examine the behavior of inter-event times in a delay-coordinate context, and then examine the output, in that context, of a sequence of simple models of tidal forcing and stress relief. We find, as might be expected, that the stress relieved by moonquakes influences their occurrence times. Our models may also provide an explanation for the opposite-polarity events observed at some clusters.

Convective system cases were identified from the Tropical Rainfall Measuring Mission (TRMM) microwave imagery and classified by the system minimum 85-GHz brightness temperature and the estimated elapsed time of propagation from terrain greater than 500 m. The speed of the midlevel jet, the magnitude of the low-level shear, and the surface equivalent potential temperature [thetas] sub(e) were greater for the intense cases compared to the nonintense cases, although the differences between the means tended to be small: less than 3 K for surface [thetas] sub(e) and less than 2 10 super(-3) s super(-1) for low-level wind shear. Hypothesis testing of a series of commonly used intensity prediction metrics resulted in significant results only for low-level metrics such as convective available potential energy and not for any of the mid- or upper-level metrics such as the 700-hPa [thetas] sub(e). None of the environmental variables or intensity metrics by themselves or in combination appeared to be reliable direct predictors of intensity. In the regional-scale analysis, the majority of intense convective systems occurred in the surface baroclinic zone where surface [thetas] sub(e) exceeded 344 K and the 700-hPa zonal wind speeds were less than -6 m s super(-1). Fewer intense cases compared to nonintense cases were associated with African easterly wave troughs. Fewer than 25% of these cases occurred in environments with detectable Saharan dust loads, and the results for intense and nonintense cases were similar. Although the discrimination between the intense and nonintense environments was narrow, the results were robust and consistent with the seasonal movement of the West African monsoon, regional differences in topography, and African easterly wave energetics.

DARF calculations for base-state climatological cloud and aerosol properties over ocean and land are performed, and then repeated after perturbing individual aerosol optical properties (aerosol optical depth, single-scattering albedo, asymmetry parameter, scale height, and anthropogenic fraction) from their base values, keeping all other parameters fixed. The total DARF uncertainty from all aerosol parameters combined is 0.5-1.0 W m super(-2), a factor of 2-4 greater than the value cited in the Intergovernmental Panel on Climate Change's (IPCC's) Fourth Assessment Report. Most of the total DARF uncertainty in this analysis is associated with single-scattering albedo uncertainty. Owing to the greater sensitivity to single-scattering albedo in cloudy columns, DARF uncertainty in all-sky conditions is greater than in clear-sky conditions, even though the global mean clear-sky DARF is more than twice as large as the all-sky DARF.

An analysis is provided of the major scales of temporal and spatial variability of the freshwater budget and the atmospheric processes responsible for the water flux changes. The satellite evaporation fluxes are compared with fields from three different reanalysis datasets [40-yr ECMWF Re-Analysis (ERA-40), ERA-Interim, and NCEP]. The results show a water deficit in the Mediterranean region that averages to about 2.4 mm day super(-1) but with a significant east-west asymmetry ranging from 3.5 mm day super(-1) in the eastern part to about 1.1 mm day super(-1) in the western part of the basin. The zonal asymmetry in the water deficit is driven by evaporation differences that are in turn determined by variability in the air-sea humidity difference in the different parts of the Mediterranean basin. The Black Sea freshwater deficit is 0.5 mm day super(-1), with maxima off the northern coast (0.9 mm day super(-1)) that are attributed to both evaporation maxima and precipitation minima there. The trend analysis of the freshwater budget shows that the freshwater deficit increases in the 1988-2005 period. The prominent increase in the eastern part of the basin is present in the satellite and all three reanalysis datasets. The water deficit is due to increases in evaporation driven by increasing sea surface temperature, while precipitation does not show any consistent trends in the period. Similarly, in the Black Sea, trends in the freshwater deficit are mainly due to evaporation, although year-to-year variability is due to precipitation patterns.

In this research LST retrievals from the International Satellite Cloud Climatology Project (ISCCP) are assimilated into the Noah land surface model and Catchment land surface model (CLSM) using an ensemble-based, offline land data assimilation system. LST is described very differently in the two models. A priori scaling and dynamic bias estimation approaches are applied because satellite and model LSTs typically exhibit different mean values and variabilities. Performance is measured against 27 months of in situ measurements from the Coordinated Energy and Water Cycle Observations Project at 48 stations. LST estimates from Noah and CLSM without data assimilation ("open loop") are comparable to each other and superior to ISCCP retrievals. For LST, the RMSE values are 4.9 K (CLSM), 5.5 K (Noah), and 7.6 K (ISCCP), and the anomaly correlation coefficients (R) are 0.61 (CLSM), 0.63 (Noah), and 0.52 (ISCCP). Assimilation of ISCCP retrievals provides modest yet statistically significant improvements (over an open loop, as indicated by nonoverlapping 95% confidence intervals) of up to 0.7 K in RMSE and 0.05 in the anomaly R. The skill of the latent and sensible heat flux estimates from the assimilation integrations is essentially identical to the corresponding open loop skill. Noah assimilation estimates of ground heat flux, however, can be significantly worse than open loop estimates. Provided the assimilation system is properly adapted to each land model, the benefits from the assimilation of LST retrievals are comparable for both models.

During the TexAQS-II Radical and Aerosol Measurement Project the combined cloud and aerosol effects reduced j(NO2) photolysis frequencies by nominally 17%, while aerosols reduced j(NO2) by 3% on six clear sky days. Reductions in actinic flux due to attenuation by clouds and aerosols correspond to reduced net ozone formation rates with a nearly one-to-one relationship. The overall reduction in the net ozone production rate due to reductions in photolysis rates by clouds and aerosols was approximately 8aappbvaaha1.

Therefore, studies of the physiology, diversity, and phylogeny of cyanobacteria inhabiting iron-depositing hot springs may provide insights into the contribution of cyanobacteria to iron redox cycling in these environments and new mechanisms of oxidative stress mitigation. In this study the morphology, ultrastructure, physiology, and phylogeny of a novel cyanobacterial taxon, JSC-1, isolated from an iron-depositing hot spring, were determined. The JSC-1 strain has been deposited in ATCC under the name Marsacia ferruginose, accession number BAA-2121. Strain JSC-1 represents a new operational taxonomical unit (OTU) within Leptolyngbya sensu lato. Strain JSC-1 exhibited an unusually high ratio between photosystem (PS) I and PS II, was capable of complementary chromatic adaptation, and is apparently capable of nitrogen fixation. Furthermore, it synthesized a unique set of carotenoids, but only chlorophyll a. Strain JSC-1 not only required high levels of Fe for growth (.40 kM), but it also accumulated large amounts of extracellular iron in the form of ferrihydrite and intracellular iron in the form of ferric phosphates. Collectively, these observations provide insights into the physiological strategies that might have allowed cyanobacteria to develop and proliferate in Fe-rich, circum-neutral environments.

The concentrations of hydroxyl (OH) and hydroperoxy (HO2) radicals were calculated by a zero-dimensional box model with each mechanism and then compared with the OH and HO2 measurements. The OH and HO2 calculated by the model with different mechanisms show similarities and differences with each other and with the measurements. First, measured OH and HO2 are generally greater than modeled for all mechanisms, with the median modeled-to-measured ratios ranging from about 0.8 (CB05) to about 0.6 (SAPRC-99). These differences indicate that either measurement errors, the effects of unmeasured species or chemistry errors in the model or the mechanisms, with some errors being independent of the mechanism used. Second, the modeled and measured ratios of HO2/OH agree when NO is about 1aappbv, but the modeled ratio is too high when NO was less and too low when NO is more, as seen in previous studies. Third, mechanism-mechanism HOx differences are sensitive to the environmental conditions - in more polluted conditions, the mechanism-mechanism differences are less. This result suggests that, in polluted conditions, the mechanistic details are less important than in cleaner conditions, probably because of the dominance of reactive nitrogen chemistry under polluted conditions.

Along similar lines of development, we have created a geomagnetic data assimilation system, MoSST-DAS, which includes a numerical geodynamo model, a suite of geomagnetic and paleomagnetic field models dating back to 5000 BCE, and a data assimilation component using a sequential assimilation algorithm. To reduce systematic errors arising from the geodynamo model, a prediction-correction iterative algorithm is applied for more accurate forecasts. This system and the new algorithm are tested with 7-year geomagnetic forecasts. The results are compared independently with CHAOS and IGRF field models, and they agree very well. Utilizing the geomagnetic field models up to 2009, we provide our prediction of 5-year mean secular variation (SV) for the period 2010-2015 up to degree L = 8. Our prediction is submitted to IGRF-11 as a candidate SV model.

We present a general methodology to analyze the spatial scales of the forcing/response relationship and apply it to simulations of historical aerosol forcing and response in four climate models. We find that the surface temperature response is not strongly sensitive to the longitude of forcing but is fairly sensitive to latitude. Surface temperature responses in the Arctic and the Southern Hemisphere extratropics, where forcing was small, show little relationship to local forcing. Restricting the analysis to 30 degree S-60 degree N, where nearly all the forcing was applied, shows that forcing strongly influences response out to 4500 km away examining all directions. The meridional length of influence is somewhat shorter (3500 km or 30 degree ), while it extends out to at least 12,000 km in the zonal direction. Substantial divergences between the models are seen over the oceans, whose physical representations differ greatly among the models. Length scales are quite consistent over 30 degree S-60 degree N land areas, however, despite differences in both the forcing applied and the physics of the models themselves. The results suggest that better understanding of regionally inhomogeneous radiative forcing would lead to improved projections of regional climate change over land areas. They also provide quantitative estimates of the spatial extent of the climate impacts of pollutants, which can extend thousands of kilometers beyond polluted areas, especially in the zonal direction.

On 2010 June 3 a bolide in Jupiter's atmosphere was simultaneously observed from the Earth by two amateur astronomers observing Jupiter in red and blue wavelengths. The bolide appeared as a flash of 2 s duration in video recording data of the planet. The analysis of the light curve of the observations results in an estimated energy of the impact of (0.9-4.0) X 10 (super 15) J which corresponds to a colliding body of 8-13 m diameter assuming a mean density of 2 g cm (super -3) . Images acquired a few days later by the Hubble Space Telescope and other large ground-based facilities did not show any signature of aerosol debris, temperature, or chemical composition anomaly, confirming that the body was small and destroyed in Jupiter's upper atmosphere. Several collisions of this size may happen on Jupiter on a yearly basis. A systematic study of the impact rate and size of these bolides can enable an empirical determination of the flux of meteoroids in Jupiter with implications for the populations of small bodies in the outer solar system and may allow a better quantification of the threat of impacting bodies to Earth. The serendipitous recording of this optical flash opens a new window in the observation of Jupiter with small telescopes. Copyright (Copyright) 2010. The American Astronomical Society.

The physics of the very near wake of the cylinder is perhaps the most challenging of them all. This region comprises the two detached shear layers, the recirculation region and wake flow. A study of the instability of the detached shear layers is important because these shear layers have a considerable impact on the dynamics of the very near wake. It has been observed experimentally that during certain periods of time that are randomly distributed, the measured fluctuating velocity component near the shear layers shows considerable amplification and it subsequently returns to its normal level (intermittency). Here, direct numerical simulations are used to accomplish a number of objectives such as confirming the presence of intermittency (computationally) and shedding light on processes that contribute significantly to intermittency and shear-layer transition/breakdown. Velocity time traces together with corresponding instantaneous vorticity contours are used in deciphering the fundamental processes underlying intermittency and shear-layer transition. The computed velocity spectra at three locations along the shear layer are provided. The computed shear-layer frequency agrees well with a power-law fit to experimental data.

Measurements were carried out with two experimental setups: (1) passing nitrogen through a humidity generator and allowing the gas stream to become saturated at a measured temperature and pressure, and (2) injecting water via a syringe pump into a nitrogen stream. Both water vapor generating devices were attached to a downstream vertically mounted water capture bed filled with 19.5g of Moisture Gone+ desiccant. The sensor consisted of two electrodes: (1) a 1/8in. dia stainless steel rod placed in the middle of the bed and (2) the outer shell of the stainless steel bed concentric with the rod. All phases of the water capture process (background, heating, absorption, desorption, and cooling) were monitored with capacitance. The measured capacitance was found to vary linearly with the water content in the bed at frequencies above 100kHz indicating dipolar motion dominated the signal; below this frequency, ionic motion caused nonlinearities in the water concentration/capacitance relationship. The desiccant exhibited a dielectric relaxation whose activation energy was lowered upon addition of water indicating either a less hindered rotational motion or crystal reorientation.

A site-specific amino-terminal transamination reaction provides a useful complement to cysteine chemistry for the covalent modification of biomolecules in this application. We demonstrate this combination to attach two different chromophores to a single biomolecule in two locations. The periplasmic glutamine binding protein from E. coli was modified with a pair of dyes suitable for fluorescence resonance energy transfer, and this conjugate exhibited an l-glutamine dependent optical response. Two periplasmic binding proteins from the thermophilic organism Thermotoga maritima, for arginine and aliphatic amino acids, were modified and evaluated similarly. All three conjugates manifested signal changes mediated by resonant energy transfer upon binding their respective ligands, with nanomolar dissociation constants and stereochemical specificity. This represents a readily generalizable method for construction of reagentless biosensors. The double-labeling strategy was also exploited for the surface attachment of a dye-labeled glutamine binding protein via a biotin-streptavidin interaction.

Energy for electric lighting is a major input to a controlled-environment crop-production system for space habitation. Day-neutral strawberry cultivars were evaluated at several different photoperiods to determine minimum lighting requirements without limiting yield or negatively impacting fruit quality. The cultivars a~Tribute', a~Seascape', and a~Fern' were grown at 14, 17, or 20h of light per day, and fruit yield was evaluated over a 31-week production period. This amounted to a difference of 2418kWhma degree 2 in energy usage between the longest and shortest photoperiods. All cultivars produced similar total fresh weight of fruit regardless of photoperiod. Volunteer tasters rated organoleptic characteristics including sweetness, tartness, texture, and overall appeal as measures of fruit quality. Generally, organoleptic attributes were not affected by photoperiod, but these attributes were somewhat dependent upon cultivar and harvest time. Cultivars under different photoperiods varied in their production of fruit over time. a~Seascape' was the most consistent producer, typically with the largest, most palatable fruit. a~Seascape' plants subsequently were grown at 10-, 12-, or 14-h photoperiods over a treatment period of 33 weeks. Photoperiod again had no significant effect on total fruit weight, although there were periodic flushes of productivity. Fruit under all photoperiods had acceptable approval ratings. A large-fruited, day-neutral strawberry cultivar such as a~Seascape' remains productive under shortened photoperiods, allowing reductions in energy and crew labor while maintaining flexibility for mixed-cropping scenarios in space.

We have subsequently found that not just separate microbial species or strains but entire microbial communities have this ability. The functional division within a microbial community on proteo- and sugarlytic links was also reflected in a microbial diet with L-sugars and D-amino acids. Several questions are addressed in this paper. Why and when was this feature developed in a microbial world? Was it a secondary de novo adaptation in a bacterial world? Or is this a piece of genetic information that has been left in modern genomes as an atavism? Is it limited exclusively to prokaryotes, or does this ability also occur in eukaryotes? In this article, we have used a broader approach to study this phenomenon using anaerobic extremophilic strains from our laboratory collection. A series of experiments were performed on physiologically different groups of extremophilic anaerobes (pure and enrichment cultures). The following characteristics were studied: 1) the ability to grow on alternate chirality enantiomers - L-sugars and D- amino acids; 2) Growthinhibitory effect of alternate chirality enantiomers; 3) Stickland reaction with alternate chirality amino acids.

We develop a method to use satellite observations of tropospheric NO sub(2) columns to provide timely estimates of trends in NO sub(x) emissions. NO sub(x) emissions increased by 33% for China and 29% for East Asia from 2003 to 2006. We examine measurements from three aircraft platforms from the INTEX-B campaign, including a Canadian Cessna taking vertical profiles of ozone near Whistler Peak. The contribution to the mean simulated ozone profiles over Whistler below 5.5 km is at least 7.2 ppbv for Asian anthropogenic emissions and at least 3.5 ppbv for global lightning NO sub(x) emissions. Tropospheric ozone columns from OMI exhibit a broad Asian outflow plume across the Pacific, which is reproduced by simulation. Mean modelled sensitivities of Pacific (30 N-60 N) tropospheric ozone columns are at least 4.6 DU for Asian anthropogenic emissions and at least 3.3 DU for lightning, as determined by simulations excluding either source. Enhancements of ozone over Canada from Asian anthropogenic emissions reflect a combination of trans-Pacific transport of ozone produced over Asia, and ozone produced in the eastern Pacific through decomposition of peroxyacetyl nitrates (PANs). A sensitivity study decoupling PANs globally from the model's chemical mechanism establishes that PANs increase ozone production by removing NO sub(x) from regions of low ozone production efficiency (OPE) and injecting it into regions with higher OPE, resulting in a global increase in ozone production by 2% in spring 2006. PANs contribute up to 4 ppbv to surface springtime ozone concentrations in western Canada. Ozone production due to PAN transport is greatest in the eastern Pacific; commonly occurring transport patterns advect this ozone northeastward into Canada. Transport events observed by the aircraft confirm that polluted airmasses were advected in this way.

Abiotic mechanisms yield racemic mixtures (D/L=1) of chiral molecules and after the death of an organism, the enantiopure chiral biomolecules slowly racemize. Several independent investigators have now established that the amino acids present in CI1 and CM2 carbonaceous meteorites have a moderate to strong excess of the L-enantiomer. Stable isotope data have established that these amino acids are both indigenous and extraterrestrial. Carbonaceous meteorites also contain many other strong chemical biomarkers including purines and pyrimidines (nitrogen heterocycles of nucleic acids); pristine and phytane (components of the chlorophyll pigment) and morphological biomarkers (microfossils of filamentous cyanobacteria). Energy dispersive X-ray Spectroscopy (EDS) analysis reveals that nitrogen is below the detectability level in most of the meteorite filaments as well as in Cambrian Trilobites and filaments of 2.7 Gya Archaean cyanobacteria from Karelia. The deficiency of nitrogen in the filaments and the total absence of sugars, of twelve of the life-critical protein amino acids, and two of the nucleobases of DNA and RNA provide clear and convincing evidence that these filaments are not modern biological contaminants. This paper reviews the chiral, chemical biomarkers morphological biomarkers and microfossils in carbonaceous meteorites. This paper reviews chiral and morphological biomarkers and discusses the missing nitrogen, sugars, protein amino acids, and nucleobases as "bio-discriminators" that exclude modern biological contaminants as a possible explanation for the permineralized cyanobacterial filaments found in the meteorites.

In addition, long range transport can deliver key nutrients normally not available to marine ecosystems in the Southern Ocean and may trigger or enhance primary productivity. However, there is a dearth of observational based studies of dust transport in the SH. This work aims to improve current understanding of dust transport in the SH by showing a characterization of two dust events originating in the Patagonia desert (south end of South America). The approach is based on a combined and complementary use of satellite retrievals (detectors MISR, MODIS, GLAS, POLDER, OMI), transport model simulation (HYSPLIT) and surface observations near the sources and aerosol measurements in Antarctica (Neumayer and Concordia sites). Satellite imagery and visibility observations confirm dust emission in a stretch of dry lakes along the coast of the Tierra del Fuego (TdF) island (54 S) and from the shores of the Colihue Huapi lake in Central Patagonia (46 S) in February 2005. Model simulations initialized by these observations reproduce the timing of an observed increase in dust concentration at the Concordia Station and some of the observed increases in atmospheric aerosol absorption (here used as a dust proxy) in the Neumayer station. The TdF sources were the largest contributors of dust at both sites. The transit times from TdF to the Neumayer and Concordia sites are 6-7 and 9-10 days respectively. Lidar observations and model outputs coincide in placing most of the dust cloud in the boundary layer and suggest significant deposition over the ocean immediately downwind. Boundary layer dust was detected as far as 1800 km from the source and 800 km north of the South Georgia Island over the central sub-Antarctic Atlantic Ocean. Although the analysis suggests the presence of dust at 1500 km SW of South Africa five days after, the limited capabilities of existing satellite platforms to differentiate between aerosol types do not permit a definitive conclusion. In addition, the model simulations show dust lifting to the free troposphere as it travels south but it could not be confirmed by the satellite observations due to cloudiness. This work demonstrates that complementary information from existing transport models, satellite and surface data can yield a consistent picture of the dust transport from the Patagonia desert to Antarctica. It also illustrates the limitation of using any of these approaches individually to characterize the transport of dust in a heavily cloudy area.

The plethora of data returned from recent planetary missions has enabled a new era in planetary geomorphic studies. Much of our understanding of planetary dune systems comes from the application of Earth analogs, wind tunnel experiments and modeling studies. Despite the range of atmospheric pressures, composition and gravity, many of the dune forms on extraterrestrial surfaces are similar to those on Earth, although some have notable differences in bedform scale and composition. As an introduction to the special issue on planetary dune systems this paper summarizes the current state of knowledge of planetary dune studies and highlights outstanding questions that require further investigation.

MISSE 6 was transported to the international Space Station (ISS) via STS 123 on March 11. 2008. The astronauts successfully attached the passive experiment containers (PEC) to external handrails of the international space station (ISS) and opened up for long term exposure. After more than a year of exposure attached to the station's exterior, the PEC with several hundred material samples returned to the earth with the STS-128 space shuttle crew that was launched on shuttle Discovery from the Kennedy Space Center, Fla., on Aug. 28. Meanwhile, MISSE 7 launch is scheduled to be launched on STS 129 mission. MISSE-7 was launched on Space Shuttle mission STS-129 on Atlantis was launched on November 16, 2009. This paper will briefly review recent efforts on MISSE 6 and MISSE 7 missions at NASA Langley Research Center (LaRC).

By MBD, we mean the problem of observing a mechanical, software, or other system and determining what failures its internal components have suffered using a generic inference algorithm and a model of the system's components and interconnections. These techniques are very attractive, suggesting a vision of machines that repair themselves, reduced costs for all kinds of endeavors, spacecraft that continue their missions even when failing, and so on. This promise inspired a broad range of activities, including our involvement over several years in flying the Livingstone and L2 onboard MBD and recovery systems as experiments on Deep Space 1 and Earth Observer 1 spacecraft. Yet, in the end, no spacecraft project adopted the technology in operations nor flew additional flight experiments. To our knowledge, no spacecraft project has adopted any other MBD technology in operations. In this paper, we present a cost/benefit analysis for MBD using expectations and experiences with Livingstone as an example. We provide an overview of common techniques for making spacecraft robust, citing fault protection schemes from recent missions. We lay out the cost, benefit, and risk advantages associated with onboard MBD and use the examples to probe each expected advantage in turn. We suggest a method for evaluating a mission that has already been flown and providing a rough estimate of the maximum value that a perfect onboard diagnosis and recovery system would have provided. By unpacking the events that must occur in order to provide value, we also identify the factors needed to compute the expected value that would be provided by a real diagnosis and recovery system. We then discuss the expected value we would estimate that such a system would have had for the Mars Exploration Rover mission. This has allowed us to identify the specific assumptions that made our expectations for MBD in this domain incorrect.

A significant part of this new initiative includes exploration of new worlds, the development of more innovative technologies, and expansion our presence in the solar system. A common theme to this initiative is the exploration of space beyond Low Earth Orbit (LEO). As currently organized, NASA does not have an Agency-level office that provides coordination of space environment research and development. This has contributed to the formation of a gap between spaceflight environments knowledge and the application of this knowledge for multi-program use. This paper outlines a concept to establish a NASA-level Applied Spaceflight Environments (ASE) office that will provide coordination and funding for sustained multi-program support in three technical areas that have demonstrated these needs through customer requests. These technical areas are natural environments characterization and modeling, materials and systems analysis and test, and operational space environments modeling and prediction. This paper will establish the need for the ASE, discuss a concept for organizational structure and outline the scope in the three technical areas.

The primary goal of this research is to determine how inspection tools are used, and how their capabilities can be verified. The research was accomplished by investigating the following tools: the Dino-Lite hand held microscope; a video Borescope, a portable bi-directional reflectance distribution function (BRDF) scatterometer; and Contamination Field Kits, suitcases which carry the very tools for inspection and verification within them. A secondary goal is to further develop an existing purge suitcase for the Operational Land Imager (OLI) and Thermal Infrared Sensor (TIRS) instruments on the Landsat Data Continuity Mission (LDCM). The purge suitcase is used as a contamination mitigation technique to keep the instruments dry and clean.

From this site, dominant IR water vapor absorption bands and continuum, saturated when viewed from the surface at lower altitudes, or in less dry locales, were investigated in detail, elucidating infrared (IR) absorption and emission in the atmosphere. Three Fourier Transform InfraRed (FTIR) instruments were at the site, the Far-Infrared Spectroscopy of the Troposphere (FIRST), the Radiation Explorer in the Far Infrared (REFIR), and the Atmospheric Emitted Radiance Interferometer (AERI). In a side-by-side comparison, these measured atmospheric downwelling radiation, with overlapping spectral coverage from 5 to 100[mu]m (2000 to 100cm super(-1)), and instrument spectral resolutions from 0.5 to 0.643cm super(-1), unapodized. In addition to the FTIR and other ground-based IR and microwave instrumentation, pressure/temperature/relative humidity measuring sondes, for atmospheric profiles to 18km, were launched from the site several times a day. The derived water vapor profiles, determined at times matching the FTIR measurement times, were used to model atmospheric radiative transfer. Comparison of instrument data, all at the same spectral resolution, and model calculations, are presented along with a technique for determining adjustments to line-by-line calculation continuum models. This was a major objective of the campaign.

Outgassed materials within the spacecraft have the potential to degrade performance of optical surfaces, thermal control surfaces, solar arrays, electronics, and detectors. One method for addressing the outgassing of materials is the use of molecular adsorbers. On Goddard Space Flight Center missions such as Hubble Space Telescope (HST), Tropical Rainfall Measuring Mission (TRMM), and SWIFT, Zeolite-coated cordierite molecular adsorbers were successfully used to collect and retain outgassed molecular effluent emanating from spacecraft materials, protecting critical contamination sensitive surfaces. However, the major drawbacks of these puck type adsorbers are weight, size, and mounting hardware requirements, making them difficult to incorporate into spacecraft designs. To address these concerns, a novel molecular adsorber coating was developed to alleviate the size and weight issues while providing a configuration that more projects can utilize, particularly contamination sensitive instruments. This successful sprayable molecular adsorber coating system demonstrated five times the adsorption capacity of previously developed adsorber coating slurries. The molecular adsorber formulation was refined and a procedure for spray application was developed. Samples were spray coated and tested for capacity, thermal optical/radiative properties, coating adhesion, and thermal cycling. The tested formulation passes coating adhesion and vacuum thermal cycling tests between +140 and -115C. Thermal radiative properties are very promising. Work performed during this study indicates that the molecular adsorber formulation can be applied to aluminum, stainless steel, or other metal substrates that can accept silicate coatings.

CERES consists of an integrated instrumentalgorithm- validation science team that provides development of higher-level products (Levels 1-3) and investigations. It involves a high level of data fusion, merging inputs from 25 unique input data sources to produce 18 CERES data products. Over 90% of the CERES data product volume involves two or more instruments.

The wide scatter in depth-diameter data from Martian craters is more pronounced than for lunar or Mercurian craters. This was previously assumed to be predominantly due to significant degrees of denudation and secondary infilling of the Martian craters. However, our data for fresh craters still exhibit a wide variation, which we interpret to be the result of comparatively higher target heterogeneity on Mars. Complex central peaks exhibit some crater diameter dependence, preferentially occurring in craters >50 km. Neither peak complexity nor geometry shows any statistical correlation with target type. Although central peak heights and aspect ratios do not exhibit any clear target dependence, they do appear to be correlated--higher peaks possess narrower aspect ratios. Floor and summit pits appear to be more common on lava targets than sedimentary targets, contrary to earlier studies with smaller sample sizes. This observation imposes additional constraints on models proposed for the origin of pits, especially those models that require the presence of volatiles in the target. The ability to correlate target type with crater morphologies/morphometries is highly contingent upon both the surface geology and the actual geology at depth. Some weak correlations may reflect our current limited understanding of the sub-surface geology of Mars. Information on the deeper lithologies acquired through future missions may help resolve the true effect of subsurface competence on intracrater structure.

Shock recovery experiments were performed by the multiple reverberation technique at pressures between 9.9 and 47.1 GPa. Shock effects were analyzed petrographically and by electron microprobe analysis. Gypsum is rapidly and efficiently disaggregated at modest pressures (approximately 24.3 GPa). Calcite is surprisingly stable and retains its characteristic high birefringence at pressures as high as 47 GPa. Modest evidence for melting is observed in the sulfate-dominated matrix of the 24.3 GPa sample and at higher pressures. However, no substantial compositional gradients associated with specific clasts were observed that would be suggestive of S-depletion (thus partial loss of SO (sub 2) ) of specific gypsum grains or of Ca-enrichment (thus partial loss of CO (sub 2) ) associated with carbonate grains. Deformation effects observed in these shock experiments on calcite and gypsum are solid-state reactions and, by comparison to solid-state shock effects in quartz from the same experiments, provide a calibration scheme for shock effects in naturally shocked rocks. However, the effects will only be observable if those effects have not been overprinted by subsequent processes such as thermal annealing or alteration.

The most-densely cratered portion of the highlands reached a state of saturation equilibrium. Large impact events, such as Orientale Basin, locally modified the prebasin crater population to approximately 2 basin radii from the basin center. Basins such as Imbrium, Orientale, and Nectaris, which are important stratigraphic markers in lunar history, are temporally distinguishable on the basis of crater statistics. The characteristics of pre- and postmare crater populations support the hypothesis that there were two populations of impactors in early solar system history and that the transition occurred near the time of the Orientale Basin event.

Most lunar terrains have spectral signatures that are consistent with known lunar anorthosite and basalt compositions. However, the data have also revealed the presence of highly evolved, silica-rich lunar soils in kilometer-scale and larger exposures, expanded the compositional range of the anorthosites that dominate the lunar crust, and shown that pristine lunar mantle is not exposed at the lunar surface at the kilometer scale. Together, these observations provide compelling evidence that the Moon is a complex body that has experienced a diverse set of igneous processes.

These lithologies are consistent with evolved rocks similar to lunar granites in the Apollo samples. The spectral character of these spots is distinct from surrounding mare and highlands material and from regions composed of pure plagioclase feldspar. The variety of landforms associated with the silicic spectral character suggests that both extrusive and intrusive silicic magmatism occurred on the Moon. Basaltic underplating is the preferred mechanism for silicic magma generation, leading to the formation of extrusive landforms. This mechanism or silicate liquid immiscibility could lead to the formation of intrusive bodies.

Thus, the stable isotopic composition of CO (sub 2) can reveal much about the history of volatiles on the planet. The Mars Phoenix spacecraft measurements of carbon isotopes [referenced to the Vienna Pee Dee belemnite (VPDB)] [delta (super 13) C (sub VPDB) = -2.5 + or - 4.3 per mil (ppm)] and oxygen isotopes [referenced to the Vienna standard mean ocean water (VSMOW)] (delta (super 18) O (sub VSMOW) = 31.0 + or - 5.7 ppm), reported here, indicate that CO (sub 2) is heavily influenced by modern volcanic degassing and equilibration with liquid water. When combined with data from the martian meteorites, a general model can be constructed that constrains the history of water, volcanism, atmospheric evolution, and weathering on Mars. This suggests that low-temperature water-rock interaction has been dominant throughout martian history, carbonate formation is active and ongoing, and recent volcanic degassing has played a substantial role in the composition of the modern atmosphere.

The airfoil model spans the entire tunnel and the span-to-chord ratio of the model is 3.26. The objective of this numerical study, in which we solve the compressible Reynolds-averaged Navier-Stokes equations in a time-resolved manner (but the solutions eventually converge to steady states), is to investigate the physical mechanisms of wind-tunnel sidewall effects on the flow, especially in the midspan region. The three-dimensional simulations predict that the Coanda jet flow is quasi-two-dimensional until the flow separates from the trailing edge of the airfoil; however, the spanwise ends of this Coanda jet sheet then three-dimensionally roll up on the side walls of the wind tunnel to form two large stream wise vortices downstream. Careful comparisons between the two- and three-dimensional simulations reveal that the wind-tunnel stream goes below the airfoil more in the three-dimensional cases than in the two-dimensional cases due to the presence of these two stream wise vortices downstream. This results in smaller lift and larger drag being praduced at the midspan of the airfoil in the three-dimensional cases than in the two-dimensional cases.

Multiple analyses of delta 18O have an average precision of Ac0.4a (2SD) in single grains of magnetite, close to plus or minus 0.3, that obtained for multiple grains of UWQ-1, a homogeneous quartz standard. In contrast, the average precision is five to ten times worse, plus or minus 2-3 (2SD), from grain-to-grain of magnetite due to variation in instrumental bias with crystal orientation. Electron backscatter diffraction shows that individual grains of magnetite are single crystals and that crystal orientation varies randomly from grain-to-grain. The crystal orientation for each magnetite grain is plotted relative to the incident angle of the SIMS primary Cs+ beam. High values of delta 18O are measured when the Cs+ beam is parallel to , from [110] to [100], preferred channeling and focusing directions for magnetite. Routine delta 18O analysis at WiscSIMS utilizes a Gaussian focused Cs+ primary beam (deep-pit mode) at primary and secondary voltages of +10kV anda10kV respectively (total impact energy 20keV). Four analytical experiments were conducted in attempts to improve the grain-to-grain precision in measured delta 18O for magnetite: (1) applying an energy offset of 50eV, (2) using a Koehler illuminated beam (shallow-pit mode), (3) reducing the total impact energy, and (4) varying the primary and secondary accelerating voltages. The best results were obtained in experiment (4) at primary/secondary accelerating voltages of +3kV/-10kV respectively with an incident Cs+ beam angle of 14 degree . The grain-to-grain precision in measured I delta 18O for magnetite improves from plus or minus 2.9 to plus or minus 0.8 (2SD) at +10kV/-10kV and +3kV/-10kV analysis respectively, while precision in single grains is plus or minus 0.4- for both. Instrumental bias in delta 18O also varies with crystal orientation for hematite at similar levels as is seen for magnetite. The grain-to-grain precision in measured delta 18O for hematite improves from plus or minus 2.1 to plus or minus 1.0 (2SD) at +10kV/10kV and +3kV/10kV analysis respectively, while precision in single grains is plus or minus 0.3 (2SD) for both. Importantly, crystal orientation effects have not been identified at levels of plus or minus 0.3 for delta 18O in silicates or other minerals analyzed by WiscSIMS though many minerals remain to be examined.

To significantly reduce the cost associated with transportation of such materials and structures from earth, it is imperative that such building materials should be synthesized primarily from Martian in situ resources. This paper illustrates the feasibility of such an approach. Experimental results are discussed to demonstrate the synthesis of polyethylene (PE) from a simulated Martian atmosphere and the fabrication of a composite material using simulated Martian regolith with PE as the binding material. The radiation shielding effectiveness of the proposed composites is analyzed using results from radiation transport codes and exposure of the samples to high-energy beams that serve as a terrestrial proxy for the GCR environment. Mechanical and ballistic impact resistance properties of the proposed composite as a function of composition, processing parameters, and thermal variations are also discussed to evaluate the multifunctionality of such in situ synthesized composite materials.

The growth of ice crystals from the vapour in both prism and basal planes was observed at temperatures of 60 degree C and 70 degree C under ice supersaturation up to 100% (200% relative humidity) at air pressures derived from the standard atmosphere in a static diffusion chamber. Crystals grew outward from a vertical glass filament, thickening in the basal plane by addition of macroscopic layers greater than 2I14m, leading to growth in the prism plane by passing of successive layers conveniently viewed by time-lapse video.

The standard AMSR-E sea-ice concentration products are produced using the National Aeronautics and Space Administration Team 2 sea-ice algorithm. The ten MODIS scenes cover portions of almost all the sea-ice regions surrounding the Antarctic continent. The AMSR-E averaged ice concentration biases relative to MODIS (AMSR-E minus MODIS) ranged from less than - 0.5% to - 18%, and the corresponding averaged root-mean-square (rms) errors ranged from 2% to 24%. One scene [October 1, 2006 (0550 UT)] had both the largest bias ( - 18%) and rms error (24%), whereas the other nine scenes had an average bias of - 1.5% and an average rms error of 4.9%. The biases and rms errors are correlated with the fractions of new ice and open water. This is consistent with the findings that the largest errors in ice concentration derived from the AMSR-E occur in the marginal ice zone (MIZ) and along the ice edge and are likely caused by sea-ice flooding in the MIZ and new-ice production at the ice edge.

Dune fields in the study area span 14 116400km2, leading to a global dune field coverage estimate of 904000km2, far less than that found on Earth. Based on distinct morphological features, the dune fields were grouped into six different classes that vary in interpreted aeolian activity level from potentially active to relatively inactive and eroding. The six dune field classes occur in specific latitude zones, with a sequence of reduced activity and degradation progressing poleward. In particular, the first signs of stabilization appear at 60 degree S., which broadly corresponds to the edge of high concentrations of water-equivalent hydrogen content (observed by the Neutron Spectrometer) that have been interpreted as ground ice. This near-surface ground ice likely acts to reduce sand availability in the present climate state on Mars, stabilizing high latitude dunes and allowing erosional processes to change their morphology. As a result, climatic changes in the content of near-surface ground ice are likely to influence the level of dune activity. Spatial variation of dune field classes with longitude is significant, suggesting that local conditions play a major role in determining dune field activity level. Dune fields on the south polar layered terrain, for example, appear either potentially active or inactive, indicating that at least two generations of dune building have occurred on this surface. Many dune fields show signs of degradation mixed with crisp-brinked dunes, also suggesting that more than one generation of dune building has occurred since they originally formed. Dune fields superposed on early and late Amazonian surfaces provide potential upper age limits of 100My on the south polar layered deposits and 3Ga elsewhere at high latitudes. No craters are present on any identifiable dune fields, which can provide a lower age limit through crater counting: assuming all relatively stabilized dune fields represent a single noncontiguous surface of uniform age, their estimated crater retention age is <10000years. An average-sized uncratered dune field (94km2) has a crater retention age <8My. This apparent youth suggests that present-day climate conditions are responsible for the observed degradation and reduced level of aeolian activity. A lack of observed transport pathways and the absence of large dune fields in the largest basins (Hellas and Argyre Planitiae) are consistent with the previously proposed idea that dune sands are not typically transported far from their source regions on Mars.

These values are low and suggest that fluid flow through impact craters, evidenced by hydrothermal systems in numerous craters, is predominantly through fracture systems. Mineral precipitation by circulating fluids would eventually seal the fractures. The focussing of hydrothermal fluid flow in fractures emphasizes their importance as potential sites for microbial colonization, and suggests that the sealing minerals are good targets to search for evidence of life.

This coating sheds dust particles utilizing anti-contamination and self-cleaning properties that minimize dust accumulation on spacecraft surfaces. Shedding of dust particles is accomplished by reducing the surface energy and the amount of surface available for attachment. The Lotus coating is designed to preserve optimal long-term performance of critical spacecraft surfaces and systems, while minimizing and/or eliminating dust accumulation. NASA is exceedingly interested in simplistic and innovative ways to mitigate dust accumulation while minimizing the impact to spacecraft mass and power requirements. Preliminary research and development indicates that the Lotus Coating has the potential to be a viable passive tool for mitigating dust on: radiator surfaces, solar array panels, habitation airlock walls, mechanism shields, astronaut EVA suits, and astronaut visors exterior coating.

Space radiation hazards are an important concern for human space flight in deep space where galactic cosmic rays (GCR) and solar energetic particles are dominated and radiation is much stronger than that in LEO (Low Earth Orbit) because in deep space there is no magnetosphere to screen charged particle and no big planet nearby to shadow the spacecraft. Research indicates that the impact of particle radiation on humans depends strongly on the particles' linear energy transfer (LET) and the radiation risk is dominated by high LET radiation. Therefore, radiation research on high LET should be emphasized and conducted systematically so as to make radiation risk as low as reasonably achievable (ALARA) for astronauts. Radiation around the moon can be measured with silicon detectors and/or CR-39 plastic nuclear track detectors (PNTDs). At present stage the silicon detectors are one of the preferred active dosimeters which are sensitive to all LET and CR-39 detectors are the preferred passive dosimeters which are sensitive to high LET (>=5 keV/km water). CR-39 PNTDs can be used as personal dosimeters for astronauts. Both the LET spectrum and the charge spectrum for charged particles in space can be measured with silicon detectors and CR-39 detectors. Calibrations for a detector system combined with the silicon detectors CRaTER (Cosmic Rays Telescope for the Effects of Radiation) from Boston University and Massachusetts Institute of Technology, and the CR-39 PNTDs from JSC (Johnson Space Center) - SRAG (Space Radiation Analysis Group) were conducted by exposing the detector system to the accelerator generated protons and heavy ions. US space mission for the radiation measurement around the moon using CRaTER was carried out in 2009. Results obtained from the calibration exposures indicate an excellent agreement between LET spectrum and charge spectrum measured with CR-39 detectors and simulated with PHITS (Particle and Heavy Ion Transport System). This paper introduces the LET spectrum method and charge spectrum method using CR-39 PNTDs and the Monte Carlo simulation method for CR-39 detectors, presents and compares the results measured with CR-39 PNTDs and simulated for CR-39 detectors exposed to heavy irons (600 MeV/n) in BNL (Brookhaven National Laboratory) in front and behind the CRaTER.

A simple yet effective runoff routing method based on a continuity equation is implemented to model horizontal transport of surface water within the Amazon basin. The GRACE observations are analyzed separately for soil moisture and surface water storages (generated from runoff), relying on their distinct spatial patterns, being disperse for soil moisture and localized for surface water. Various effective velocities for storage transport are tested against the GRACE observations. When the model runoff is routed with an uniform velocity of 30 cm/s, the annual variation of the resulting surface water storage is generally found to be larger than the satellite measurements and ground gauge data by a factor of 1.5 or higher. The peak annual anomaly of surface water storage is observed around the midstream of the Amazon main stem. However, the runoff routing simulations present the peak amplitude consistently around the delta (downstream), unless the increasing velocity in a downstream region is used. As complements to the ground gauge data, the satellite observations provide unique 'spatial' information of water cycle parameters. Our analysis indicates possible shortcomings in the certain LSM mass transport scheme between atmosphere and land surface, particularly the production of too large seasonal variations in runoff (and maybe too little variations in evapotranspiration), and the dynamic characteristics of surface water transport within the Amazon basins.

DO - http://dx.doi.org/10.1029/2010GC003214 ER - TY - JOUR T1 - ExploreNEOs; I, Description and first results from the warm Spitzer near-Earth object survey AN - 1371761568; 2013-048725 AB - We have begun the ExploreNEOs project in which we observe some 700 Near-Earth Objects (NEOs) at 3.6 and 4.5 mu m with the Spitzer Space Telescope in its Warm Spitzer mode. From these measurements and catalog optical photometry we derive albedos and diameters of the observed targets. The overall goal of our ExploreNEOs program is to study the history of near-Earth space by deriving the physical properties of a large number of NEOs. In this paper, we describe both the scientific and technical construction of our ExploreNEOs program. We present our observational, photometric, and thermal modeling techniques. We present results from the first 101 targets observed in this program. We find that the distribution of albedos in this first sample is quite broad, probably indicating a wide range of compositions within the NEO population. Many objects smaller than 1 km have high albedos (> or =0.35), but few objects larger than 1 km have high albedos. This result is consistent with the idea that these larger objects are collisionally older, and therefore possess surfaces that are more space weathered and therefore darker, or are not subject to other surface rejuvenating events as frequently as smaller NEOs.

For the galactic or extragalactic astronomer, these solar system bodies can introduce appreciable uncertainty into the source identification process. We discuss an infrared color discrimination tool that may be used to distinguish between solar system objects and extrasolar sources. We employ four Spitzer Legacy data sets, the First Look Survey-Ecliptic Plane Component (FLS-EPC), SCOSMOS, SWIRE, and GOODS. We use the Standard Thermal Model to derive FLS-EPC main belt asteroid (MBA) diameters of 1-4 km for the numbered asteroids in our sample and note that several of our solar system sources may have fainter absolute magnitude values than previously thought. A number of the MBAs are detected at flux densities as low as a few tens of mu Jy at 3.6 mu m. As the FLS-EPC provides the only 3.6-24.0 mu m observations of individual asteroids to date, we are able to use this data set to carry out a detailed study of asteroid color in comparison to astrophysical sources observed by SCOSMOS, SWIRE, and GOODS. Both SCOSMOS and SWIRE have identified a significant number of asteroids in their data, and we investigate the effectiveness of using relative color to distinguish between asteroids and background objects. We find a notable difference in color in the IRAC 3.6-8.0 mm and MIPS 24 mu m bands between the majority of MBAs, stars, galaxies, and active galactic nuclei, though this variation is less significant when comparing fluxes in individual bands. We find median colors for the FLS-EPC asteroids to be [F(5.8/3.6), F(8.0/4.5), F(24/8)]=(4.9+ or -1.8, 8.9+ or -7.4, 6.4+ or -2.3). Finally, we consider the utility of this technique for other mid-infrared observations that are sensitive to near-Earth objects, MBAs, and trans-Neptunian objects. We consider the potential of using color to differentiate between solar system and background sources for several space-based observatories, including Warm Spitzer, Herschel, and WISE.

In the American west, operational forecasts for spring-summer streamflow rely heavily on snow-water storage and are often issued at the time of maximum snow accumulation. However, forecasts issued earlier can also show skill, particularly if proxy information for soil moisture, such as antecedent rainfall, is also used as a predictor. Studies using multiple regression approaches and/or model-produced streamflows indeed suggest that information on soil moisture-a relatively underappreciated predictor-can improve streamflow predictions. Here, we quantify the relative contributions of early-season snow and soil moisture information to the skill of streamflow forecasts more directly and comprehensively: in a suite of land-modelling systems, we use the snow and soil moisture information both together and separately to derive seasonal forecasts. Our skill analysis reveals that early-season snow-water storage generally contributes most to skill, but the contribution of early-season soil moisture is often significant. In addition, we conclude that present-generation macroscale land-surface models forced with large-scale meteorological data can produce estimates of water storage in soils and as snow that are useful for basin-scale prediction.

The new method complements the traditional, direct measurement of aerosol radiative forcing efficiency from horizontal flight legs below gradients of aerosol optical thickness, and is particularly useful over heterogeneous land surfaces and for homogeneous aerosol layers where the horizontal gradient method is impractical. Using data collected by the Solar Spectral Flux Radiometer (SSFR) and the Ames Airborne Tracking Sunphotometer (AATS-14) during the MILAGRO (Megacity Initiative: Local and Global Research Observations) experiment, we validate an over-ocean spectral aerosol forcing efficiency from the new method by comparing with the traditional method. Retrieved over-land aerosol optical properties are compared with in-situ measurements and AERONET retrievals. The spectral forcing efficiencies over ocean and land are remarkably similar and agree with results from other field experiments.

For example, phenology is widely used as a diagnostic of ecosystem response to global change. In addition, phenology influences seasonal scale fluxes of water, energy, and carbon between the land surface and atmosphere. Increasingly, the importance of phenology for studies of habitat and biodiversity is also being recognized. While many data sets related to plant phenology have been collected at specific sites or in networks focused on individual plants or plant species, remote sensing provides the only way to observe and monitor phenology over large scales and at regular intervals. The MODIS Global Land Cover Dynamics Product was developed to support investigations that require regional to global scale information related to spatio-temporal dynamics in land surface phenology. Here we describe the Collection 5 version of this product, which represents a substantial refinement relative to the Collection 4 product. This new version provides information related to land surface phenology at higher spatial resolution than Collection 4 (500-m vs. 1-km), and is based on 8-day instead of 16-day input data. The paper presents a brief overview of the algorithm, followed by an assessment of the product. To this end, we present (1) a comparison of results from Collection 5 versus Collection 4 for selected MODIS tiles that span a range of climate and ecological conditions, (2) a characterization of interannual variation in Collections 4 and 5 data for North America from 2001 to 2006, and (3) a comparison of Collection 5 results against ground observations for two forest sites in the northeastern United States. Results show that the Collection 5 product is qualitatively similar to Collection 4. However, Collection 5 has fewer missing values outside of regions with persistent cloud cover and atmospheric aerosols. Interannual variability in Collection 5 is consistent with expected ranges of variance suggesting that the algorithm is reliable and robust, except in the tropics where some systematic differences are observed. Finally, comparisons with ground data suggest that the algorithm is performing well, but that end of season metrics associated with vegetation senescence and dormancy have higher uncertainties than start of season metrics.

The Atenguillo River, interior to the Jalisco Block, has incised the bedrock units of the Jalisco Block, including Cretaceous ash flow tuff, granite, as well as younger volcanic lava flows. To study incision rates, knickpoint propagation, and the uplift rate of the region samples from nine different points along the Atenguillo channel were collected for 36Cl exposure age dating. Exposure ages along the length of the channel are high near the head of the basin where the river meanders in a broad plain. Ages are younger at the knickpoints and downstream where the river cuts deeply and forms a canyon. Incision rates measured at different points along the channel also correlate with channel slope and age. Low incision rates are measured in the oldest part of the channel near the head (station B; 2.5mm/year), and just above the knickpoints (station C; 0.6mm/year and station G; 1.4mm/year). The incision rates are highest just below the knickpoints (station F; 2.4mm/year) and farther downstream (stations H and I; 5.6 and 2.9mm/year, respectively). The high incision rates can be attributed to subduction-related uplift of the Jalisco Block. Other features attributable to uplift are emergent paleoshorelines and uplifted marine sediments along the coast; and relatively lower incision rates were measured north of the Jalisco Block.

In the present study, human epithelial cells were exposed in vitro to I[sup3-rays at a dose rate of 17mGy/h or secondary neutrons of 25mGy/h. The secondary neutrons have a broad energy spectrum that simulates the Earth's atmosphere at high altitude, as well as the environment inside spacecrafts like the Russian MIR station and the International Space Station (ISS). Chromosome aberrations in the exposed cells were analyzed using the multicolor banding in situ hybridization (mBAND) technique with chromosome 3 painted in 23 colored bands that allows identification of both inter- and intrachromosome exchanges including inversions. Comparison of present dose responses between I[sup3-rays and neutron irradiations for the fraction of cells with damaged chromosome 3 yielded a relative biological effectiveness (RBE) value of 26Ac4 for the secondary neutrons. Our results also revealed that secondary neutrons of low dose rate induced a higher fraction of intrachromosome exchanges than I[sup3-rays, but the fractions of inversions observed between these two radiation types were indistinguishable. Similar to the previous findings after acute radiation exposures, most of the inversions observed in the present study were accompanied by other aberrations. The fractions of complex type aberrations and of unrejoined chromosomal breakages were also found to be higher in the neutron-exposed cells than after I[sup3-rays. We further analyzed the location of the breaks involved in chromosome aberrations along chromosome 3, and observed hot spots after I[sup3-ray, but not neutron, exposures.

However the global and regional impacts of the direct, indirect and semi-direct aerosol effects are highly uncertain, due to the complex nature of aerosol evolution and the way that mixed, aged aerosols interact with clouds and radiation. A detailed aerosol microphysical scheme, MATRIX, embedded within the GISS climate model is used in this study to present a quantitative assessment of the impact of microphysical processes involving black carbon, such as emission size distributions and optical properties on aerosol cloud activation and radiative effects. Our best estimate for net direct and indirect aerosol radiative flux change between 1750 and 2000 is -0.56 W/m super(2). However, the direct and indirect aerosol effects are quite sensitive to the black and organic carbon size distribution and consequential mixing state. The net radiative flux change can vary between -0.32 to -0.75 W/m super(2) depending on these carbonaceous particle properties at emission. Taking into account internally mixed black carbon particles let us simulate correct aerosol absorption. Absorption of black carbon aerosols is amplified by sulfate and nitrate coatings and, even more strongly, by organic coatings. Black carbon mitigation scenarios generally showed reduced radiative fluxeswhen sources with a large proportion of black carbon, such as diesel, are reduced; however reducing sources with a larger organic carbon component as well, such as bio-fuels, does not necessarily lead to a reduction in positive radiative flux.

Of particular interest are the world's ultraslow spreading ridges that were the last to be demonstrated to host high-temperature venting but may host systems particularly relevant to prebiotic chemistry and the origins of life. Here we report evidence for previously unknown, diverse, and very deep hydrothermal vents along the approximately 110 km long, ultraslow spreading Mid-Cayman Rise (MCR). Our data indicate that the MCR hosts at least three discrete hydrothermal sites, each representing a different type of water-rock interaction, including both mafic and ultramafic systems and, at approximately 5,000 m, the deepest known hydrothermal vent. Although submarine hydrothermal circulation, in which seawater percolates through and reacts with host lithologies, occurs on all mid-ocean ridges, the diversity of vent types identified here and their relative geographic isolation make the MCR unique in the oceans. These new sites offer prospects for an expanded range of vent-fluid compositions, varieties of abiotic organic chemical synthesis and extremophile microorganisms, and unparalleled faunal biodiversity-all in close proximity.

Their formation is an important free radical chain termination step ending production of ozone and possibly affecting formation of secondary organic aerosol. ANs also represent a potentially large, unmeasured contribution to OH reactivity and are a major pathway for the removal of nitrogen oxides from the atmosphere. Numerous studies have investigated the role of nitrate formation from biogenic compounds and in the remote atmosphere. Less attention has been paid to the role ANs may play in the complex mixtures of hydrocarbons typical of urban settings. Measurements of total alkyl and multifunctional nitrates, NO sub(2), total peroxy nitrates (PNs), HNO sub(3) and a representative suite of hydrocarbons were obtained from the NASA DC-8 aircraft during spring of 2006 in and around Mexico City and the Gulf of Mexico. ANs were observed to be 10-20% of NO sub(y) in the Mexico City plume and to increase in importance with increased photochemical age. We describe three conclusions: (1) Correlations of ANs with odd-oxygen (O sub(x)) indicate a stronger role for ANs in the photochemistry of Mexico City than is expected based on currently accepted photochemical mechanisms, (2) AN formation suppresses peak ozone production rates by as much as 40% in the near-field of Mexico City and (3) ANs play a significant role in the export of NO sub(y) from Mexico City to the Gulf Region.

14918604 AB - The irreversible entropy production (i.e. the dissipation) has three distinct modes due to viscous, heat and species-mass fluxes. Computations of the dissipation and its modes are conducted using transitional states obtained from Direct Numerical Simulations (DNS) of O sub(2)/H sub(2) and C sub(7)H sub(16)/N sub(2) temporal mixing layers at thermodynamically supercritical pressure. A non-dimensionalization of the mathematical expression for each dissipation mode is first performed and representative reference values computed using the DNS database are utilized to highlight the order of magnitude of each mode and their relative importance. For more quantitative results, the importance of each dissipative mode is assessed both at the DNS scale and at scales determined by filter sizes from four to sixteen times the DNS grid spacing. The subgrid-scale (SGS) dissipation is computed by subtracting the filtered-field dissipation from the DNS-field dissipation. For each species system, three layers are considered having different initial Reynolds number and perturbation wavelength. For all layers, it is found that the species-mass flux contribution dominates both the DNS and SGS dissipation due to high density-gradient-magnitude (HDGM) regions which are a distinctive physical aspect of these layers. Backscatter, indicated by regions of negative SGS dissipation, is found in a substantial portion (15-60%) of the domain, and decreases only slightly with increasing filter width. Regions of the most intense negative and positive SGS dissipation strongly correlate with the HDGM regions. On a domain-average basis, the proportional contribution of each dissipation mode to the total is similar at the DNS and SGS scales, indicating scale-similarity. The proportion of the species-mass dissipation mode to the total is remarkably similar in value across all simulations whether at the DNS or SGS scale. For each mode and the total, the SGS contribution to the DNS-field dissipation is only species-system and filter-size dependent but nearly independent of the initial Reynolds number and perturbation wavelength. The SGS contribution is smaller for O sub(2)/H sub(2) layers than for C sub(7)H sub(16)/N sub(2) ones, but increases more rapidly with increasing filter width. The implications of these results for Larger Eddy Simulation modeling are discussed.

This bright light diffracts from instrument structures, rattles around and invariably contaminates measurements. Astrophysical observations also are impacted by stray light that obscures very dim objects and degrades signal to noise in spectroscopic measurements. Stray light is controlled by utilizing low reflectance structural surface treatments and by using baffles and stops to limit this background noise. In 2007 GSFC researchers discovered that Multiwalled Carbon Nanotubes (MWCNTs) are exceptionally good absorbers, with potential to provide order-of-magnitude improvement over current surface treatments and a resulting factor of 10,000 reduction in stray light when applied to an entire optical train. Development of this technology will provide numerous benefits including: a.) simplification of instrument stray light controls to achieve equivalent performance, b.) increasing observational efficiencies by recovering currently unusable scenes in high contrast regions, and c.) enabling low-noise observations that are beyond current capabilities. Our objective was to develop and apply MWCNTs to instrument components to realize these benefits. We have addressed the technical challenges to advance the technology by tuning the MWCNT geometry using a variety of methods to provide a factor of 10 improvement over current surface treatments used in space flight hardware. Techniques are being developed to apply the optimized geometry to typical instrument components such as spiders, baffles and tubes. Application of the nanostructures to alternate materials (or by contact transfer) is also being investigated. In addition, candidate geometries have been tested and optimized for robustness to survive integration, testing, launch and operations associated with space flight hardware. The benefits of this technology extend to space science where observations of extremely dim objects require suppression of stray light.

This sensor is capable to measure the large electric fields for large dust devils without saturation. However, to quantify the electric charges and the field strength it is critical to calibrate the mechanical stiffness of the sensor devices. We performed a technical feasibility study of the Nano E-field Sensor stiffness by a non-contact stiffness measurement method. The measurement is based on laser Doppler vibrometer measurement of the thermal noise due to energy flunctuations in the devices. The experiment method provides a novel approach to acquire data that is essential in analyzing the quantitative performance of the E-field Nano Sensor. To carry out the non-contact stiffness measurement, we fabricated a new Single-Walled Carbon Nanotube (SWCNT) E-field sensor with different SWCNTs suspension conditions. The power spectra of the thermal induced displacement in the nano E-field sensor were measured at the accuracy of picometer. The power spectra were then used to derive the mechanical stiffness of the sensors. Effect of suspension conditions on stiffness and sensor sensitivty was discussed. After combined deformation and resistivity measurement, we can compare with our laboratory testing and field testing results. This new non-contact measurement technology can also help to explore to other nano and MEMS devices in the future.

ATLAST will be placed in orbit about the Sun-Earth L2 point and will experience constant exposure to the sun. The insulation on the optical tube and sunshade serve to cold bias the telescope which helps to minimize thermal gradients. The objective is to maintain the primary mirror at 280K with an active thermal control system. The geometric model of the primary mirror, optical tube, sun baffles, and sunshade was developed using Thermal Desktop1. A detailed model of the primary mirror was required in order to characterize the static performance and thermal stability of the mirror during maneuvers. This is important because long exposure observations, such as extra-solar terrestrial planet finding and characterization, require a very stable observatory wave front. Steady state thermal analyses served to predict mirror temperatures for several different sun angles. Transient analyses were performed in order to predict thermal time constant of the primary mirror for a 20 degree slew and a 30 degree roll maneuver. This paper describes the thermal model and provides details of the geometry, thermo-optical properties, and the solar environment that influences the thermal performance. All assumptions that were used in the analysis are also documented. Estimates of mirror heater power requirements are reported. The thermal model is used to predict gradients across and through the primary mirror using an idealized boundary temperature on the back and sides of the mirror of 280 K.

Forecasts initialized in June 2006 using ocean analyses from an assimilation that uses flow-dependent background error covariances are compared with those using static error covariances that are not flow dependent. The flow-dependent error covariances reflect the error structures related to the background ENSO instability and are generated by the coupled breeding method. The ocean analyses used in this study result from the assimilation of temperature and salinity, with the salinity data available from Argo floats. Of the analyses, the one using information from the coupled bred vector (BV) replicates the observed equatorial long wave propagation best and exhibits more warming features leading to the 2006 El Nino event. The forecasts initialized from the BV-based analysis agree best with the observations in terms of the growth of the warm anomaly through two warming phases. This better performance is related to the impact of the salinity analysis on the state evolution in the equatorial thermocline. The early warming is traced back to salinity differences in the upper ocean of the equatorial central Pacific, while the second warming, corresponding to the mature phase, is associated with the effect of the salinity assimilation on the depth of the thermocline in the western equatorial Pacific. The series of forecast experiments conducted here show that the structure of the salinity in the initial conditions is important to the forecasts of the extension of the warm pool and the evolution of the 2006 El Nino event.

Furthermore, only a small 1-2m space telescope may be realistic for a mission in the foreseeable future, which puts strong demands on the performance of the imaging instrument. Fortunately, an efficient coronagraph called the Phase Induced Amplitude Apodization (PIAA) coronagraph may enable Earth-like planet imaging for such small telescopes if any exist around the nearest stars. In this paper, we report on the latest results from a testbed at the NASA Ames Research Center focused on testing the PIAA coronagraph. This laboratory facility was built in 2008 and is designed to be flexible, operated in a highly stabilized air environment, and to complement efforts at NASA JPL's High Contrast Imaging Testbed. For our wavefront control we are focusing on using small Micro-Electro-Mechanical-System deformable mirrors (MEMS DMs), which promises to reduce the size of the beam and overall instrument, a consideration that becomes very important for small telescopes. In this paper, we briefly describe our lab and methods, including the new active thermal control system, and report the demonstration of 5.4x10 super(-8) average raw contrast in a dark zone from 2.0 - 5.2 [lambda]/D. In addition, we present an analysis of our current limits and solutions to overcome them.

To improve our understanding of carbon dynamics on continental margins, a dissolved organic matter (DOM) model was developed and imbedded within an existing coupled ocean circulation-biogeochemical model of the U.S. East coast. A model simulation with the DOM module was compared with the reference model (without the DOM module) to illustrate the role of DOM dynamics in coastal ocean biogeochemical cycling. Model results reveal that the progressive release of dissolved organic nitrogen (DON) in the ocean's upper layer during summer increases the regenerated primary production by 30-300%, which, in turn, enhances the dissolved organic carbon (DOC) production mainly from phytoplankton exudation in the upper layer and solubilization of particulate organic matter (POM) deeper in the water column. This analysis suggests that DOM is a necessary component for representing ecosystem functioning and organic fluxes in models because DOM (1) is a major organic pool directly related to primary production, (2) decouples partially the carbon and nitrogen cycles (through carbon excess uptake, POM solubilization and DOM mineralization) and (3) is intimately linked to the residence time of water masses for its distribution and export. The seasonally produced DOC on the shelf can be exported to the open ocean by horizontal transport at comparable rates (1-2molCm super(-2)yr super(-1)) to particulate organic carbon burial in the southern U.S. Mid-Atlantic Bight (MAB).

This study leads us to conclude that Y-86032 likely originated on the lunar farside. Y-86032 is composed of several types of feldspathic clasts, granulitic breccias, and minor basaltic clasts set in a clastic matrix. We identify an "An97 anorthosite" that has An contents similar to those of nearside FANs. Mg' (= molar Mg/(Mg+Fe) x 100) values vary significantly from nearly equal 45 to nearly equal 80 covering the ranges of both nearside FANs and the Mg' gap between FANs and the Mg-suite. A light-gray feldspathic (LG) breccia making up nearly equal 20% of the investigated slab (5.2 x 3.6 cm (super 2) ) mainly consists of fragments of anorthosites ("An93 anorthosite") more sodic than nearside FANs. LG also contains an augite-plagioclase clast which either could be genetically related to the An93 anorthosite or to slowly-cooled basaltic magma intruded into the precursor rock. The Na-rich nature of both An93 anorthosite and this clast indicates that the LG breccia was derived from a relatively Na-rich but incompatible-element-poor source. The Mg' variation indicates that the "An97 anorthosite" is a genomict breccia of several types of primary anorthosites. Granulitic breccias in Y-86032 have relatively high Mg' in mafic minerals. The highest Mg' values in mafic minerals for the "An97 anorthosite" and granulitic breccias are similar to those of Mg-rich lithologies recently described in Dhofar 489. Basaltic clasts in the dark-gray matrix are aluminous, and the zoning trends of pyroxene are similar to those of VLT or LT basalts. The crystallization of these basaltic clasts pre-date the lithification age of the clastic matrix at nearly equal 3.8 Ga. The low K contents of plagioclase in both the anorthositic and basaltic clasts and generally low incompatible element abundances in all the lithologies in Y-86032 indicate that KREEP was not involved during the formation of the precursor lithologies. This observation further suggests that urKREEP did not exist in the source regions of these igneous lithologies. All these facts support the idea that Y-86032 was derived from a region far distant from the PKT and that the lithic clasts and fragments are indigenous to that region. An An97 anorthositic clast studied here has distinct Sm-Nd isotopic systematics from those previously found for another An97 anorthositic clast and "An93 anorthosite", and suggests either that An97 anorthosites come from isotopically diverse sources, or that the Sm-Nd isotopic systematics of this clast were reset nearly equal 4.3 Ga ago. These lines of geochemical, isotopic, and petrologic evidence suggest that the lunar crust is geochemically more heterogeneous than previously thought.

AN - 755154964; 2010-079202 AB - It has been 35 years since NASA undertook a bold journey, to search for life on another planet, by sending the Viking landers (Figure 1) to the surface of Mars. The general consensus was that both landers failed to find conclusive evidence of extant Martian organisms. NASA started the journey with the best car on the market, with the transmission in high gear, but after hitting a big bump in the road, it decided to downshift and take a closer look at the map. Subsequent studies focused on characterizing the physical, chemical, and geological environment on Mars today and in the past, before any more bold attempts were made to directly search for life. This led to an unanticipated but necessary detour that has provided us with some of the best highlights of the journey so far. Examples are the discovery of widespread secondary minerals that formed in the presence of liquid water, the detection of ground ice in the high latitudes of both hemispheres, including the polar caps, and the direct analysis of ground ice by the Phoenix mission in 2008. These research efforts have also allowed us to vastly improve the tools we now have at our disposal. But let there be no mistake: This detour was a necessary course of action, because it was futile to search for life on Mars without understanding the Martian environment.

For example, the nutrients and harmful substances contained in dust can affect the development of microalgae in the ocean. The initial composition of dust and its chemical transformations during transport determine the way dust interacts with ocean ecosystems and, more generally, with clouds and the climate as a whole. These new developments open the door for future research initiatives that will require the collaboration of scientists from several disciplines to fully understand the effects of dust in the atmosphere and ocean ecosystems.

Associated with this exposure are multiple risks, i.e., probabilities that certain aspects of an astronaut's health or performance will be degraded. The management of these risks requires that such probabilities be accurately predicted, that the actual exposures be verified, and that comprehensive records be maintained. Implicit in these actions is the fact that, at some point, a decision has been made to accept a certain level of risk. This paper examines ethical and practical considerations involved in arriving at a determination that risks are acceptable, roles that the parties involved may play, and obligations arising out of reliance on the informed consent paradigm seen as the basis for ethical radiation risk acceptance in space.

According to the state government's recent inventory, California's carbon budget is presently dominated by 115 MMTCE per year in fossil fuel emissions of CO"2 (>85% of total annual GHG emissions) to meet energy and transportation requirements. Other notable (non-ecosystem) sources of carbon GHG emissions in 2004 were from cement- and lime-making industries (7%), livestock-based agriculture (5%), and waste treatment activities (2%). The NASA-CASA (Carnegie Ames Stanford Approach) simulation model based on satellite observations of monthly vegetation cover (including those from the Moderate Resolution Imaging Spectroradiometer, MODIS) was used to estimate net ecosystem fluxes and vegetation biomass production over the period 1990-2004. California's annual NPP for all ecosystems in the early 2000s (estimated by CASA at 120 MMTCE per year) was roughly equivalent to its annual fossil fuel emission rates for carbon. However, since natural ecosystems can accumulate only a small fraction of this annual NPP total in long-term storage pools, the net ecosystem sink flux for atmospheric carbon across the state was estimated at a maximum rate of about 24 MMTCE per year under favorable precipitation conditions. Under less favorable precipitation conditions, such as those experienced during the early 1990s, ecosystems statewide were estimated to have lost nearly 15 MMTCE per year to the atmosphere. Considering the large amounts of carbon estimated by CASA to be stored in forests, shrublands, and rangelands across the state, the importance of protection of the natural NPP capacity of California ecosystems cannot be overemphasized.

AN - 733998170; 20582595 AB - In this study, the ability of the C(60) fullerene derivative DF-1 to protect radiosensitive cells from the effects of high doses of gamma irradiation was examined. Earlier reports of DF-1's lack of toxicity in these cells were confirmed, and DF-1 was also observed to protect both human lymphocytes and rat intestinal crypt cells against radiation-induced cell death. We determined that DF-1 protected both cell types against radiation-induced DNA damage, as measured by inhibition of micronucleus formation. DF-1 also reduced the levels of reactive oxygen species in the crypt cells, a unique capability of fullerenes because of their enhanced reactivity toward electron-rich species. The ability of DF-1 to protect against the cytotoxic effects of radiation was comparable to that of amifostine, another ROS-scavenging radioprotector. Interestingly, localization of fluorescently labeled DF-1 in fibroblast was observed throughout the cell. Taken together, these results suggest that DF-1 provides powerful protection against several deleterious cellular consequences of irradiation in mammalian systems including oxidative stress, DNA damage, and cell death.

This mission will tightly constrain the cosmological parameters describing the accelerating expansion of the universe. The current candidate designs are based on extensive examination of the interplay of requirements for the leading techniques being considered for space borne observation: Baryon Acoustic Oscillation (BAO), Type Ia Supernovae (SN), and gravitational Weak Lensing (WL). All techniques require very large fields of view across the visible/near infrared spectrum; BAO uniquely requires a moderate dispersion wide field spectroscopy capability. Weak lensing requires very good stability and knowledge of the point spread function in order to enable detection of local variations in galaxy ellipticities caused by the intervening dark matter. SN imaging spectroscopy should be done to high photometric signal to noise in order to make best use of these 'standard candles.' We have studied medium class and smaller, "Probe" class implementations enabling from one to three of these techniques. We describe two concepts that were submitted to the 2010 Astrophysics Decadal review as well as current concepts.

These incidents have the potential to cause minor inconveniences, extra paperwork, schedule hits, extra analysis or in the worst case, performance degradation. The Solar Dynamics Observatory (SDO) experienced various types of incidences in different phases of build and launch. The purpose of this study is to discuss the major contamination-related lessons learned during the design, production, testing, and launch of the Solar Dynamics Observatory to help future programs avoid similar incidents.

The SXS is a true spatial-spectral instrument, where each spatially discrete pixel functions as a high-resolution spectrometer. Here we discuss the SXS detector subsystem that includes the detector array, the anticoincidence detector, the first stage amplifiers, the thermal and mechanical staging of the detector, and the cryogenic bias electronics. The design of the SXS detector subsystem has significant heritage from the Suzaku/XRS instrument but has some important modifications that increase performance margins and simplify the focal plane assembly. Notable improvements include x-ray absorbers with significantly lower heat capacity, improved load resistors, improved thermometry, and a decreased sensitivity to thermal radiation. These modifications have yielded an energy resolution of 3.5-4.0 eV FWHM at 6 keV for representative devices in the laboratory, giving considerable margin against the 7 eV instrument requirement. We expect similar performance in flight.

Tests were performed to evaluate the accuracy and precision of sulfur isotope analysis by SIMS in a set of seven well-characterized, isotopically homogeneous natural sulfide standards. The spot-to-spot and grain-to-grain precision for delta 34S is plus or minus 0.3 for chalcopyrite and pyrrhotite, and plus or minus 0.2 for pyrite (2SD) using a 1.6nA primary beam that was focused to 10 mu m diameter with a Gaussian-beam density distribution. Likewise, multiple delta 34S measurements within single grains of sphalerite are within plus or minus 0.3. However, between individual sphalerite grains, delta 34S varies by up to 3.4a and the grain-to-grain precision is poor ( plus or minus 1.7, n =20). Measured values of delta 34S correspond with analysis pit microstructures, ranging from smooth surfaces for grains with high delta 34S values, to pronounced ripples and terraces in analysis pits from grains featuring low delta 34S values. Electron backscatter diffraction (EBSD) shows that individual sphalerite grains are single crystals, whereas crystal orientation varies from grain-to-grain. The 3.4a variation in measured delta 34S between individual grains of sphalerite is attributed to changes in instrumental bias caused by different crystal orientations with respect to the incident primary Cs+ beam. High delta 34S values in sphalerite correlate to when the Cs+ beam is parallel to the set of directions , from [111] to [110], which are preferred directions for channeling and focusing in diamond-centered cubic crystals. Crystal orientation effects on instrumental bias were further detected in galena. However, as a result of the perfect cleavage along {100} crushed chips of galena are typically cube-shaped and likely to be preferentially oriented, thus crystal orientation effects on instrumental bias may be obscured. Test were made to improve the analytical precision of delta 34S in sphalerite, and the best results were achieved by either reducing the depth of the analysis pits using a Koehler illuminated primary beam, or by lowering the total impact energy from 20keV to 13keV. The resulting grain-to-grain precision in delta 34S improves from plus or minus 1.7 to better than 0.6 (2SD) in both procedures. With careful use of appropriate analytical conditions, the accuracy of SIMS analysis for delta 34S approaches plus or minus 0.3 (2SD) for chalcopyrite, pyrite and pyrrhotite and plus or minus 0.6 for sphalerite. Measurements of delta 34S in sub-20 mu m grains of pyrite and sphalerite in 3.5Ga cherts from the Pilbara craton, Western Australia show that this analytical technique is suitable for in situ sulfur isotope thermometry with plus or minus 50 degree C accuracy in appropriate samples, however, sulfides are not isotopically equilibrated in analyzed samples.

However, HSCT is associated with a non-negligible risk of both transplantation-related mortality (TRM) and morbidity. Great interest and relevant expectations have been raised by the introduction in the clinical practice of reduced-intensity preparative regimens, which may represent an effective strategy to reduce the toxicity of transplantation and may also help reduce the incidence of late effects. Although some reports have documented the feasibility of using reduced-intensity preparative regimens for successfully treating patients with TM, a high incidence of graft failure has been frequently reported. Recently, treosulfan-based myeloablation has been demonstrated to be associated with limited extra-medullary toxicity and a high rate of sustained donor engraftment. This novel approach is a promising alternative for reducing the risk of life-threatening complications and increasing the number of TM patients successfully cured with an allograft.

The laboratory experiments and computational modeling done at the NASA Ames Research Center to create a collection of PAH IR spectra relevant to test and refine the PAH hypothesis have been assembled into a spectroscopic database. This database now contains over 800 PAH spectra spanning 2-2000 mu m (5000-5 cm (super -1) ). These data are now available on the World Wide Web at http://www.astrochem.org/pahdb www.astrochem.org/pahdb.

Despite a number of recent studies, little is known about their abundances in the solid state. This is particularly the case for low-mass protostars, for which only the launch of the Spitzer Space Telescope has permitted high-sensitivity observations of the ices around these objects. In this work, we investigate the approximately 8-10 mu m region in the Spitzer IRS (InfraRed Spectrograph) spectra of 41 low-mass young stellar objects (YSOs). These data are part of a survey of interstellar ices in a sample of low-mass YSOs studied in earlier papers in this series. We used both an empirical and a local continuum method to correct for the contribution from the 10 mu m silicate absorption in the recorded spectra. In addition, we conducted a systematic laboratory study of NH (sub 3) - and CH (sub 3) OH-containing ices to help interpret the astronomical spectra. We clearly detect a feature at approximately 9 mu m in 24 low-mass YSOs. Within the uncertainty in continuum determination, we identify this feature with the NH (sub 3) nu (sub 2) umbrella mode and derive abundances with respect to water between approximately 2% and 15%. Simultaneously, we also revisited the case of CH (sub 3) OH ice by studying the nu (sub 4) C-O stretch mode of this molecule at approximately 9.7 mu m in 16 objects, yielding abundances consistent with those derived by Boogert et al. based on a simultaneous 9.75 and 3.53 mu m data analysis. Our study indicates that NH (sub 3) is present primarily in H (sub 2) O-rich ices, but that in some cases, such ices are insufficient to explain the observed narrow FWHM. The laboratory data point to CH (sub 3) OH being in an almost pure methanol ice, or mixed mainly with CO or CO (sub 2) , consistent with its formation through hydrogenation on grains. Finally, we use our derived NH (sub 3) abundances in combination with previously published abundances of other solid N-bearing species to find that up to 10%-20% of nitrogen is locked up in known ices.

The high vacuum environment on the lunar surface leads to some unusual physical and dynamical phenomena involving dust grains with high adhesive characteristics, and levitation and transportation over long distances. Knowledge of the dust grain charges and equilibrium potentials is important for understanding a variety of physical and dynamical processes in the interstellar medium, and heliospheric, interplanetary/planetary, and lunar environments. It has been well recognized that the charging properties of individual micron-/submicron-size dust grains are expected to be substantially different from the corresponding values for bulk materials. In this paper, we present experimental results on the charging of individual 0.2-13 mu m size dust grains selected from Apollo 11 and 17 dust samples, and spherical silica particles by exposing them to mono-energetic electron beams in the 10-200 eV energy range. The dust charging process by electron impact involving the SEEs discussed is found to be a complex charging phenomenon with strong particle size dependence. The measurements indicate substantial differences between the polarity and magnitude of the dust charging rates of individual small-size dust grains, and the measurements and model properties of corresponding bulk materials. A more comprehensive plan of measurements of the charging properties of individual dust grains for developing a database for realistic models of dust charging in astrophysical and lunar environments is in progress.
