TY - JOUR T1 - Principal modes of interannual and decadal variability of summer rainfall over South America AN - 18358518; 5312678 AB - Using the Climate Prediction Center (CPC) Merged Analysis of Precipitation (CMAP) product together with the Goddard Earth Observing System (GEOS) reanalysis and the National Center for Environmental Prediction (NCEP) sea-surface temperature (SST) data, we have conducted a diagnostic study of the interannual and decadal scale variability of principal modes of summer rainfall over South America for the period 1979-1995. By filtering the annual and short (< 12 months) time-scale variations, results of empirical orthogonal function analysis show three leading modes of rainfall variation identified with interannual, decadal and long-term variability. Together, these modes explain more than half the total variance of the filtered data. The first mode is highly correlated with El Nino-Southern Oscillation (ENSO), showing a regional rainfall anomaly pattern largely consistent with previous results. This mode captures the summer season interannual variability, not only the Northeast Brazil drought but also its connection with excessive rainfall over Southern Brazil and the Ecuador coast in El Nino years. Another distinctive feature is the strengthening of the low-level flow along the eastern foothills of the eastern Andes, signifying an enhancement of the South American summer monsoon in response to an El Nino anomaly. The decadal variation displays a meridional shift of the Inter-Tropical Convergence Zone (ITCZ), which is tied to the anomalous cross-equatorial SST gradient over the Atlantic and the eastern Pacific. Associated with this mode is a large-scale mass swing between polar regions and the mid-latitudes. Over the South Atlantic and the South Pacific, the anomalous subtropical high and the associated anomalous surface wind are dynamically consistent with the distribution of local SST anomalies, suggesting the importance of atmospheric forcing at the decadal time scale. The long-term variation shows that since 1980 there has been a decrease of rainfall from the northwest coast to the southeast subtropical region and a southwards shift of the Atlantic ITCZ, leading to increased rainfall over northern and eastern Brazil. Possible links of this mode to the observed SST warming trend over the subtropical South Atlantic and to the interdecadal SST variation over the extratropical North Atlantic are discussed.

AN - 72375093; 11769318 AB - Normalized difference vegetation index data from the polar-orbiting National Oceanic and Atmospheric Administration meteorological satellites from 1982 to 1999 show significant variations in photosynthetic activity and growing season length at latitudes above 35 degrees N. Two distinct periods of increasing plant growth are apparent: 1982-1991 and 1992-1999, separated by a reduction from 1991 to 1992 associated with global cooling resulting from the volcanic eruption of Mt. Pinatubo in June 1991. The average May to September normalized difference vegetation index from 45 degrees N to 75 degrees N increased by 9% from 1982 to 1991, decreased by 5% from 1991 to 1992, and increased by 8% from 1992 to 1999. Variations in the normalized difference vegetation index were associated with variations in the start of the growing season of -5.6, +3.9, and -1.7 days respectively, for the three time periods. Our results support surface temperature increases within the same period at higher northern latitudes where temperature limits plant growth.

AN - 72207150; 11604078 AB - The patterns of DSBs induced in the genome are different for sparsely and densely ionizing radiations: In the former case, the patterns are well described by a random-breakage model; in the latter, a more sophisticated tool is needed. We used a Monte Carlo algorithm with a random-walk geometry of chromatin, and a track structure defined by the radial distribution of energy deposition from an incident ion, to fit the PFGE data for fragment-size distribution after high-dose irradiation. These fits determined the unknown parameters of the model, enabling the extrapolation of data for high-dose irradiation to the low doses that are relevant for NASA space radiation research. The randomly-located-clusters formalism was used to speed the simulations. It was shown that only one adjustable parameter, Q, the track efficiency parameter, was necessary to predict DNA fragment sizes for wide ranges of doses. This parameter was determined for a variety of radiations and LETs and was used to predict the DSB patterns at the HPRT locus of the human X chromosome after low-dose irradiation. It was found that high-LET radiation would be more likely than low-LET radiation to induce additional DSBs within the HPRT gene if this gene already contained one DSB.

AN - 72206554; 11604093 AB - Projecting cancer risks from exposure to space radiation is highly uncertain because of the absence of data for humans and because of the limited radiobiology data available for estimating late effects from the high-energy and charge (HZE) ions present in the galactic cosmic rays (GCR). Cancer risk projections involve many biological and physical factors, each of which has a differential range of uncertainty due to the lack of data and knowledge. We discuss an uncertainty assessment within the linear-additivity model using the approach of Monte Carlo sampling from subjective error distributions that represent the lack of knowledge in each factor to quantify the overall uncertainty in risk projections. Calculations are performed using the space radiation environment and transport codes for several Mars mission scenarios. This approach leads to estimates of the uncertainties in cancer risk projections of 400-600% for a Mars mission. The uncertainties in the quality factors are dominant. Using safety standards developed for low-Earth orbit, long-term space missions (>90 days) outside the Earth's magnetic field are currently unacceptable if the confidence levels in risk projections are considered. Because GCR exposures involve multiple particle or delta-ray tracks per cellular array, our results suggest that the shape of the dose response at low dose rates may be an additional uncertainty for estimating space radiation risks.

AN - 72206405; 11604058 AB - For over 30 years, astronauts in Earth orbit or on missions to the moon have been exposed to space radiation comprised of high-energy protons and heavy ions and secondary particles produced in collisions with spacecraft and tissue. Large uncertainties exist in the projection of risks of late effects from space radiation such as cancer and cataracts due to the paucity [corrected] of epidemiological data. Here we present epidemiological [corrected] data linking an increased risk of cataracts for astronauts with higher lens doses (>8 mSv) of space radiation relative to other astronauts with lower lens doses (<8 mSv). Our study uses historical data for cataract incidence in the 295 astronauts participating in NASA's Longitudinal Study of Astronaut Health (LSAH) and individual occupational radiation exposure data. These results, while preliminary because of the use of subjective scoring methods, suggest that relatively low doses of space radiation may predispose crew to [corrected] an increased incidence and early appearance of cataracts.

Image processing algorithms were developed to identify a target region on a plant leaf. A novel algorithm to recover view depth was developed by using a camera equipped with a computer-controlled zoom lens. The methodology has improved depth recovery resolution over a conventional monocular imaging technique. An algorithm was also developed to find a maximum enclosed circle on a leaf surface so the conical field-of-view of an infrared temperature sensor could be filled by the target without peripheral noise. The center of the enclosed circle and the estimated depth were used to define the sensor 3-D location for accurate plant temperature measurement. JF - Transactions of the ASAE.

AN - 71321699; 12088031 AB - Light and auxin antagonistically regulate hypocotyl elongation. We have investigated the physiological interactions of light and auxin in the control of tomato (Lycopersicon esculentum Mill.) hypocotyl elongation by studying the auxin-insensitive mutant diageotropica (dgt). The length of the hypocotyls of the dgt mutant is significantly reduced when compared to the wild type line Ailsa Craig (AC) in the dark and under red light, but not under the other light conditions tested, indicating that auxin sensitivity is involved in the elongation of hypocotyls only in these conditions. Similarly, the auxin transport inhibitor naphthylphthalamic [correction of naphtylphtalamic] acid (NPA) differentially affects elongation of dark- or light-grown hypocotyls of the MoneyMaker (MM) tomato wild type. Using different photomorphogenic mutants, we demonstrate that at least phytochrome A, phytochrome B1 and, to a much lesser extent [correction of extend], cryptochrome 1, are necessary for a switch from an auxin transport-dependent elongation of hypocotyls in the dark to an auxin transport-independent elongation in the light.

There is at least one deep mantle reservoir rich in (super 3) He and Ne that was trapped early in Earth history, with minimum concentrations obtained by closed system calculations. Ne isotopes indicate the presence of a component that has a solar composition. Xe isotopes indicate that extensive late losses occurred from the mantle as well as from the atmosphere. Calculations based on a simple two-stage evolution provide times of losses of up to approximately 100 Ma after the formation of the solar system from both the mantle and the atmosphere. These losses appear to have depleted the rare gases by > or =97%; therefore, there originally was at least two orders of magnitude more rare gases than now present. Mechanisms for the capture of rare gases soon after the start of the solar system into the deep Earth (or Earth-forming materials) must provide these high initial concentrations, presumably in the high-energy environment of planetary accretion where strong degassing of solids might be expected to have occurred. A mechanism that satisfies these requirements is the dissolution in a magma ocean of rare gases from a dense primary atmosphere. A massive atmosphere of solar composition would have been captured if the Earth had formed prior to dispersal of the solar nebula. The underlying mantle would have melted due to the energy of accretion and the blanketing effect of this atmosphere. Rare gases would then have entered the molten Earth by dissolution at the surface and downward advection. For typical solubility coefficients, a total pressure of approximately 100 atm and surface temperatures of > approximately 2500 degrees C are required to dissolve sufficient rare gases to account for the initial lower mantle concentrations. While Xe in the mantle is isotopically exchanging with the primary atmosphere, it will be buffered to a solar composition; therefore, somewhat less Xe must be trapped prior to the late loss event for longer periods of exchange. As solidification of the mantle proceeded outward during cooling, the distributions of retained rare gases would have been determined by the history of surface pressure and temperature during the coupled cooling of the Earth and atmosphere. The giant impact proposed for Moon formation may have been responsible for the inferred substantial and late gas losses from the deep mantle as well as from the atmosphere. Constraints on the timing of Moon formation derived from Hf-W systematics and simulations of the giant impact are consistent with the Xe isotope constraints for gas loss.

This is the largest aperture optical instrument ever utilized for meteor detection. While the observing system is sensitive down to stars of +18 astronomical magnitude under optimum conditions, when corrections for meteor motion are applied the majority of the meteors collected fall in the absolute magnitude range from +5 to +10, corresponding to photometric masses from about 10 (super -7) to 10 (super -9) kg. This is largely due to the fact that the field of view of the LMT was only 0.28 degrees , so that only a small portion of the luminous meteor trail was recorded. While the flux of these small (1.4X10 (super -9) kg) Leonid meteors is low (on the order of one Leonid meteor per hour per square kilometer perpendicular to the Leonid), we do have clear evidence that the Leonid stream contains particles in the mass range studied here. The data showed a possibly significant peak in Leonid flux (9.3+ or -3.5) for the 1 h period from 11:00 to 12:00 U.T. 1999 November 17 (solar longitude 234.653 to 234.695, epoch 2000.0), although the main trend of these results is a broad low-level Leonid activity. There is evidence that small meteoroids are more widely distributed in the Leonid stream, as would be expected from cometary ejection stream models. As would be expected from an extrapolation of mass distribution indices for brighter meteors, the vast majority of meteors at this size are sporadic. The LMT is a powerful detector of sporadic meteors, with an average non-Leonid detection rate of more than 140 meteor events per hour.

Instead a two-stage process is required, whereby melts were modified by both fractionation and assimilation of lower crustal material, before rising and ponding at shallower crustal levels (15-20 km maximum), where a combination of fractional crystallization, plagioclase phenocryst formation, and periodic melt replenishment took place. These shallow crustal chambers acted as feeders for the numerous dykes. One hypothesis compatible with these observations involves an extensive rising plume that would provide heterogeneous melts over a large area accompanied by stresses that could produce a radial pattern of dykes. In a search for indications of lateral magma flow, a comparison of longitudinal variations in composition along four sample traverses across the western subswarm showed no truly consistent trends. However, Hf/Zr values are highest in the traverse nearest the focal region and lowest in the traverse 250 km away, suggesting a change in magma composition with distance from the focus of the swarm, the assumed plume centre. Given the presently available data, the variations cannot be attributed to progressive fractionation during lateral magma flow in the crust nor to a northward increase in amounts of contamination by known lower crustal assimilants, all of which have Hf/Zr ratios higher than the distal values recorded by the dykes. Instead the variations are thought to reflect a possible compositional zonation of the plume head. The distortion of the western subswarm from a simple radiating pattern may have been facilitated by a low viscosity lower crust, softened by Matachewan igneous activity, and is consistent with deformation by the Blezardian orogen at about 2.2-2.4 Ga.

The depth, width, and spectral placement of the 1- and 2-mu m mafic silicate absorption features in the ground-based reflectance spectrum of 4 Vesta (the archetype V-class asteroid) indicate that orthopyroxene is a major phase in its surface mineralogy. In 1994 and 1996, Hubble Space Telescope observations confirmed albedo differences across Vesta's surface, and produced shape and topographic information about Vesta. Dynamical studies previously revealed that a family of mainbelt asteroids is associated with 4 Vesta. Taxonomic surveys have found numerous, smaller asteroids with Vesta-like 1-mu m spectral absorption features. To date, work on the surface mineralogy of Vesta was the definitive analysis for one of these V-class asteroids since no complete near-infrared spectrum of another V-type has existed. The case for a Vesta-HED meteorite connection has a firm mineralogical foundation. Previous spectral data have suggested a link to additional V-class asteroids, but until now that supposed association has not been mineralogically tested. We present a near-infrared reflectance spectrum of asteroid 1929 Kollaa obtained at the NASA Infrared Telescope Facility covering the critical 1- and 2-mu m absorption features. Parameters derived from these features yield values for the orthopyroxene composition and plagioclase-to-orthopyroxene abundance ratio that fall well within the range for basaltic achondrites and 4 Vesta. Additional spectral parameters allow us to further constrain the orthopyroxene composition of 1929 Kollaa, which is consistent with that of cumulate eucrites. This demonstrates that 1929 Kollaa formed deep in the eucritic crust of Vesta near the diogenitic zone. Furthermore, it establishes the first mineralogical (genetic) connection between a Vesta-region asteroid with both 4 Vesta and a subset of the HED meteorites.

The location represents a unique occurrence of springs discharging from the surface of a large ice sheet and precipitating "travertine-like" deposits of native sulphur, gypsum and calcite as well as releasing H2S. The presence of sulphur in three oxidation states indicates a complex series of redox reactions. Physical and chemical conditions of the spring water and surrounding environment argue for biologically mediated reactions. Bacteria counts of 2 to 3 X 104 cells/ml, as well as SEM images of biofilm and individual cells confirm bacteria are present in the spring system. Sulphur is most likely derived from thick evaporite (anhydrite) beds of the underlying Otto Fiord Formation. Geological constraints suggest a circulation depth of greater than 1.5 km, implying a topography driven flow system, with an active biological community, may operate within an area covered by extensive ice sheets and thick (>500 m) permafrost.

A JEOL 6340F field emission scanning electron microscope (FE-SEM), IXRF energy dispersive x-ray spectrometer (EDS), and a Phillips XL30 environmental electron microscope (ESEM) are used to analyze benthic detrital and evaporite deposits from waters less than 2 meters deep. We are interested in identifying the chemical signatures of the microbial representatives inhabiting both detrital and evaporite surfaces, including their possible methods of fossilization. Clay and silt sized detrital samples are frequently pitted with many of them containing halite crystals. Halite crystals can also occur as relatively pure aggregates. Sand sized particles indicate pitting with secondary clay formation and magnesium deposits. ESEM analysis indicates the presence of rods (785 nm to 3.62 micrometers), and coccoid to irregular coccoid shapes (828 nm to 1.65 micrometers) within the microbial size range. FE-SEM indicates the presence of elliptically shaped mineralized microbes. Some contain cytoplasmic extensions. All of the mineralized microbes possess calcium ion signatures, a metallic ion that can be associated with microbial activity. Biofilm development is apparently limited within our samples, as even freshly collected material does not possess thick accumulations similar to Bahamian saline lakes. Dead Sea deposits contain a variety of microbial forms with limited biofilm development. Fossilized forms are represented by elliptical to rod-shaped forms with the absence of fossilized coccoid shapes. This is significant as there are coccoid forms present, but apparently fossilization is marginal to nonexistent.

Examples of these applications are described below. Electron-beam excited x-ray fluorescence of materials is enabled in air, in the Atmospheric Electron X-ray Spectrometer (AEXS), by means of a micro-fabricated, electron-transmissive membrane. The 200-nm-thick membrane is capable of withstanding a differential pressure of one atmosphere and isolates the vacuum of the electron source from the atmospheric pressure ambient. We have demonstrated proof-of-principle for the AEXS instrument concept and are working towards building a portable instrument prototype. The Force Detected Nuclear Magnetic Resonance Spectrometer (FDNMRS) is a novel, microfabricated device capable of detecting and distinguishing the presence of water and other organic compounds in physisorbed or chemisorbed states. The ultimate device is only 2 mm in diameter is and capable of characterizing 60-micron-sized particles. Proof-of-principle for the spectrometer was demonstrated using a mostly conventionally-machined spectrometer that was 25 times the size of the ultimate device. The proton NMR peak from a water droplet was successfully detected as were J-coupling splittings in an organic molecule using spin-echo techniques. Work is progressing on the realization of the MEMS-scale device. A high aspect ratio lithography technique know by its acronym LIGA is being used to fabricate a micro-quadrupole filter for mass spectrometer applications. The process involves the electroplating of nickel within a "mold" created from a thick-film (2-3 mm thick) Poly Methyl MethAcrylate (PMMA) film. Finally, an electron beam lithography fabricated NEMS device is being developed for "Single Molecule Detection". The so-called Force Detected Optical Spectrometer (FDOS) works on the principle of dipole-dipole interactions causing a nanomechanical resonator to vibrate at frequencies of approx. 500 MHz. This work is very preliminary and the principle of the device and some initial results will be described.

The LEAP is based on the Field Ion Microscope (FIM) and utilizes a rapidly pulsed, localized electric field to evaporate a needle-shaped specimen one atom at a time. The ions are accelerated through an aperture in an accelerating microelectrode. A two-dimensional detector, such as a delay-line detector, collects the ions with single atom sensitivity. Since the LEAP is capable of identifying each atom, the accumulated data allows the three-dimensional reconstruction of the sample's structure and composition at the nanometer scale. The LEAP extends the capabilities of the traditional Atom Probe Field Ion Microscope (APFIM) to semi- and non-conducting materials. Focused ion beam secondary ion mass spectroscopy (FIB-SIMS) is a relatively new analytical technique based upon the Focused Ion Beam (FIB) microscope which uses a finely focused beam of gallium ions from a liquid metal source to sputter the sample. The sputtered ions are collected by a Secondary Ion Mass Spectrometer (SIMS) resulting in elemental maps as a function of depth with resolution approaching 20 nm. Focused ion beam secondary ion mass spectroscopy has yet to be widely applied to geological specimens. Compositional changes and phase differences are measurable on small scales with FIB-SIMS, and difficulties due to differential sputtering in conventional SIMS analyses are overcome by sampling at specific depths rather than continuously profiling the sample. The FIB-SIMS provides a bridge between Energy Dispersive Spectroscopy (EDS) in the Scanning Electron Microscope (SEM) and facilitates the fabrication of samples for LEAP, Transmission Electron Microscopy (TEM) and Electron Energy Loss Spectroscopy (EELS). Initial results of FIM and FIB-SIMS analyses of a metamorphic magnetite sample containing disk-shaped exsolution lamellae approximately 40 nm in diameter, 1-3 nm thick and about 104 platelets/mu m (super 3) will be discussed. The FIB-SIMS cross-sectioning, imaging and chemical analysis of a geomicrobiological sample will also be presented.

Examples of these scales are spatial distribution, temporal scale, and various electromagnetic spectral scales. The magnitude of the observation varies, depending upon the type of measurement scale in consideration, and a large signal (that is, high contrast of signal to background intensities) in one scale of observation does not necessarily correlate to the same magnitude response in some other scale of observation for the same sample. The Center for Life Detection at JPL is interested in discovering the full range of chemical and structural biosignatures that can be present in sediment and rock. To that end, we have explored a number of methods and technologies that yield complementary data sets, which, considered together, can provide the evidence to make good statistical decisions about whether or not evidence for life is being detected in geological materials. Here, I will present both chemical and structural data acquired at both various scales and various magnitudes and address some of the issues pertinent to the acquisition, handling and interpretation of these observations.

These methods are also of significant practical value, because lidar metric analysis reduces large volumes of point elevations into linear features attributed with essential morphological variables that are ideally suited for inclusion in Geographic Information Systems. Lidar change metrics calculated for north Assateague Island were applied in a pattern recognition procedure that yielded a morphodynamic classification for a recent annual cycle. This analysis revealed the relative magnitude and fine scale alongshore variation in the importance of coastal changes over the study area during a defined time period between two airborne lidar surveys. More generally, this analysis demonstrates the value of lidar metrics in both examining large lidar data sets for coherent trends, and in building hypotheses on processes of barrier island evolution. Recent advances in airborne lidar instrumentation have the potential to enhance multi-temporal lidar change analysis of barrier islands by enabling the simultaneous surveying of "bald earth" topography and adjacent shallow bathymetry. The NASA Experimental Advanced Airborne Research Lidar (EAARL) provides cross-environment surveys by the use of a scanning pulsed blue-green wavelength laser combined with a receiver that records the entire waveform of each reflected laser pulse. In addition to integrated topographic/bathymetric surveying, the NASA EAARL enables discrimination of ground surface elevations in the presence of some vegetation, and thereby removes a significant potential source of error in lidar-based analyses of geomorphic change.

Processing and release of these data are currently in progress. This new data set opens several opportunities for geologic investigations. Geologic features and processes are commonly evident from their topographic expression. Depositional landforms are usually distinctive in morphology, and erosional processes commonly reveal lithologic contrasts and structural patterns. Satellite imagery has provided detailed views of the Earth's landforms in recent decades, but the third dimension (topographic height) has generally been obscure and interpretable only from natural time-of-observation shade patterns. Site by site derivation of elevation models from stereo optical imagery has been cumbersome, expensive, and subject to obscuration by clouds. SRTM eliminates these difficulties. SRTM data are particularly effective in combination with satellite imagery. Anaglyphs and color stereo pairs (with user specified vertical exaggeration) are easily generated and analyzed on standard desktop computers with simple and basic software and hardware. However, SRTM data are also an effective analysis resource even when visualized solely. User controlled shaded relief and/or color coded height can substitute for image overlays and can be viewed in two or three dimensions. SRTM will produce the first detailed views of regional topography for many parts of the world, which should lead to greater understandings of tectonic, fluvial, glacial, eolian, and mass wasting patterns and processes.

Studies by Brigmon, using 16S rRNA analysis, indicate five genera of sulfate-reducing bacteria. Morphological observations with a field emission scanning electron microscope (FESEM) and an environmental electron microscope (ESEM) indicate diatoms, filamentous, rod-, ovoid- and spheroid-shaped features. Energy dispersive x-ray spectroscopy (EDS) indicates that the features contain magnesium, sulfur, silicon and calcium. The matrix material is primarily calcium carbonate. Examination of fresh fracture surfaces of the stromatolite samples reveals abundant spheroids composed of four distinct size populations: large (mu = 5.3 mm), medium (mu = 2.0 mm), small (mu = 0.55 mm), and tiny (mu = 0.13 mm). Surface textures vary from smooth to rough. The two larger classes of spheroids are likely to be fossilized bacteria coccoids; they occur in clusters, are closely associated with the biofilm, have a limited size range, and are primarily carbonate composition. The small and tiny spheres are frequently embedded in smooth, filmy biofilms, which vary in appearance from thick to filamentous to web-like to vesiculated. Averaging at 0.13 microns each, the tiny spheres are unlikely to be fossilized bacteria because of extremely small size and unusual composition: they are made of primarily magnesium and silicon, with no definitive carbon. We propose that they may be precipitates analogous to features described by Allen et al. (2000). In addition to the coccoidal forms, the biofilm samples also contain abundant rod and dumbbell structures, varying in size from 2-4 microns lengthwise and similar to those produced by Chafetz et al. (1991). EDS analyses indicate calcite composition. We interpret these rods, hollow filaments, and dumbbell-shaped forms to be calcite precipitates nucleated by microbes. If there was water once present on the surface of Mars or Europa, it is possible that subtidal pools formed that were similar to Storr's Lake. Stromatolites could be the universal first step in life's mass aggregation, in any environment where bacteria-like organisms form. Future work on stromatolites may further indicate their usefulness as biomarkers.

Structural or trapped water remains a minor or trace phase in many asteroids, while water ice is a major constituent of comets. Meteorites and interplanetary dust particles (IDPs) are samples of asteroids and comets that have reached the Earth. A class of primitive meteorites -- the carbonaceous chondrites -- shows evidence for extensive water:rock interactions. In the CI-type and in many of the CM-type chondrites (two of several subgroups divided according to petrologic and compositional characteristics), the primary mineralogy has been nearly completely replaced with an assemblage of clay minerals, oxides, carbonates, and sulfates. Evaporite minerals observed in CI chondrites include calcite, dolomite-ankerite, magnesite-siderite, gypsum, epsomite, and blodite. The CM chondrite assemblage is similar except that they lack the highly soluble Mg-rich sulfates. The alteration occurred very quickly, within 50-100 Ma of the formation time ( approximately 4.5 Ga ago) of the parent bodies. The secondary minerals formed from brine-like fluids at temperatures below approximately 100-150C and at moderate water:rock ratios. Some ordinary chondrites (another major class of stony meteorites) also contain traces of evaporite minerals (halite and sylvite). Fluid inclusions in these salts also indicate precipitation from concentrated brines. I-Xe isotope systematics indicate that the ordinary chondrite salts formed within 2 Ma of the formation time of the parent asteroid ( approximately 4.6 Ga). Cometary IDPs show little to no evidence for aqueous interactions, while those from asteroidal sources show comparable levels of alteration to the CI chondrites. Siderite-magnesite solid solutions are a common, minor component of these asteroidal IDPs. Primitive carbonaceous chondrites contain up to 5% carbon, which was also affected by the early aqueous interactions. Over 400 pre-biotic organic compounds have been identified in CM chondrites. IDPs are even more carbon-rich and contain as much as approximately 50 wt. % carbon, much in the form of complex organic chemicals that survive entry through the Earth's atmosphere intact. Asteroids and comets have provided significant portions of the total water inventories and pre-biotic organic matter to the terrestrial planets, including Earth.

Light sustains oxygenic photosynthesis, which in turn provides energy, organic matter and oxygen to the community. Due to both absorption and scattering phenomena, incident light is transformed with depth in the mat, both in intensity and spectral composition. Motile photosynthesizers optimize their position with respect to this light gradient. When photosynthesis ceases at night, the upper layers of the mat become reduced and sulfidic. Counteracting gradients of oxygen and sulfide combine to provide daily-contrasting environments separated on a scale of a few mm. The functional complexity of mats, coupled with the highly proximal and ordered spatial arrangement of biota, offers the potential for a staggering number of interactions. At a minimum, the products of each functional group of microorganisms affect the other groups both positively and negatively. For example, cyanobacteria generate organic matter (potential substrates) but also oxygen (a toxin for many anaerobes). Anaerobic activity recycles nutrients to the photosynthesizers but also generates potentially toxic sulfide. The combination of benefits and hazards of light, oxygen and sulfide promotes the allocation of the various essential mat processes between light and dark periods, and to various depths in the mat. Observations of mats have produced numerous surprises. For example, obligately anaerobic processes can occur in the presence of abundant oxygen, highly reduced gases are produced in the presence of abundant sulfate, meiofauna thrive at high sulfide concentrations, and the mats' constituent populations respond to environmental changes in complex ways. While photosynthetic bacteria dominate the biomass and productivity of the mat, nonphotosynthetic, anaerobic processes constitute the ultimate biological filter on the ecosystem's emergent biosignatures, including those sedimentary textures, organic compounds, and minerals that enter the fossil record. The ability of cyanobacterial mats to channel abundant solar energy into the creation and maintenance of complex structures and processes has created a multitude of consequences, both for sedimentation and for the early evolution of our biosphere.

These include about 90 visible impact craters but more than 550 features that are not visible in Viking imagery. Similar QCDs occur in the ancient cratered highlands of Mars. Their wide distribution, lack of association with known volcanic or tectonic regions, subdued and shallow profiles like those expected for buried impacts, and the shape of their cumulative frequency curves all indicate the "MOLA-found" QCDs are most likely buried impact basins. The very large number in northern terrains suggests the lowlands of Mars, below a veneer of young plains-forming units, are very old, and that the lowlands formed very early in martian history. Cumulative frequency curves for the visible and buried QCDs in the lowlands were compared over the same diameter range with similar curves for highland QCDs in the Noachis-Arabia area. The cumulative number of lowland "MOLA-found" basins per unit area is greater than that for visible impact basins in the highlands, but less than that for buried highland basins. The visible highlands in Noachis-Arabia are on average Middle Noachian in age, and the cumulative crater density is consistent with this. The buried lowland surface is therefore older than Middle Noachian and may be as old as the Early Noachian. This implies that the crustal dichotomy on Mars formed very early, and provides a temporal constraint on the processes that could produce the lowlands, favoring those that occur early and quickly.

AN - 50305867; 2002-059748 AB - Recent Mars Orbiter Camera (MOC) images and Mars Orbiter Laser Altimeter (MOLA) topography from the Mars Global Surveyor (MGS) Spacecraft have led several research teams to suggest geologically recent (10-100 m.y. ago) volcanism within Elysium Planitia and Amazonis Planitia that--in some areas--may have been emplaced over ice-rich ground. Other work has pointed to the possibility that the same rifts serve as a source for both the volcanism and the water. MOLA data provides us with new abilities to 1) provide recognition of low relief, low albedo variation volcanic or fluvial features not apparent in available images, 2) constrain estimated flow rates from edifice geometry or channel geometry and regional slope measurements, and 3) topographically track these volcanic and fluvial features to their apparent sources. We find that the volcanism in this region is well-expressed in a series of topographically fresh rift and low shield eruptions. Shield and regional slopes are quite low, with shield flank slopes ranging from 0.14 to 0.3 degrees and regional slopes of 0.01 to 0.04 degrees. Some shields have extensive associated flows, and several are constructed over rift segments. In general, the volcanism appears to be a relatively topographically fresh expression of plains style volcanism. Our edifice and channel models provide evidence for lower volcanic production rates than would be derived for flood-type basaltic provinces. Model calculations for typical basaltic or basaltic andesite rheologies yield very plausible volcanic flow rates (e.g. 1000 cubic meters/second). Rift and small shield sources are evident in the topographic data for much of the youngest volcanism, and we concur with prior suggestions that some of the volcanic and fluvial features appear to originate at common rift sources. Given the apparent youth from both topographic freshness and from existing crater dating work for the fluvial and the volcanism features, this region provides compelling evidence for the overlap of volcanic and hydrologic domains for the martian near-surface and surface environments in the recent geologic past. From the apparent age range of flows within the region, this is clearly a long-lived volcanic province, and future hydrologic and/or volcanic events are still conceivable.

It is commonly believed that many of the (non-aeolian) surface features are the result of aqueous activity, although other possible mechanisms such as erosion and deposition by liquid carbon dioxide, clathrate, and/or flowing lava, have also been proposed. Martian rock samples (meteorites from Mars), however, confirm that water has been actively present near the Martian surface. The Martian meteorites are igneous rocks (diabasic, basaltic, ultramafic), but traces of aqueously-precipitated secondary minerals, such as salts and phyllosilicates, are found along fractures and in voids in the rocks. The salts commonly occur as isolated microscopic grains or small clusters of grains. Some of the salts and other alteration products are demonstrably Martian. The distinction between possible Martian phases and terrestrial contaminants is not always clear, however. Martian salts seem to be very similar to those found in marine-type evaporites on Earth, and include carbonates, Ca-sulfate, Mg-sulfate, and halite. Earth-like layered sequences have not yet been observed in Martian occurrences. Ages of the Martian salts range from 3.9 Ga to less than 165 Ma, indicating that aqueous processes have been active on Mars for a very long time. The salts themselves commonly show evidence of weathering, suggesting that Martian aqueous activity may have been episodic. It is important to understand the Martian salts in order to decipher the near-surface history of Mars. Furthermore, the presence of evaporites on Mars has strong implications for the search for life there. The evaporites, along with other products of aqueous alteration, indicate that many of the components necessary for life on Earth, such as circulating water, potential nutrients dissolved in the water, and temperatures overlapping with the range for known organisms, have been available on Mars, possibly for a very large part of geologic history.

Such an increase can be estimated on a global scale by combining satellite estimates of UV irradiance at the ocean surface from the Total Ozone Mapping Spectrometer (TOMS) satellite instrument with the Sea-viewing Wide Field-of-view Sensor (SeaWiFS) satellite ocean color measurements in the visible spectral region. In this paper we propose a model of seawater optical properties in the UV spectral region based on the case 1 water model in the visible range. The inputs to the model are standard monthly SeaWiFS products: chlorophyll concentration and the diffuse attenuation coefficient at 490 nm. Penetration of solar UV radiation to different depths in open ocean waters is calculated using the radiative transfer quasi-single scattering approximation (QSSA). The accuracy of the QSSA approximation in the water is tested using more accurate codes. Sensitivity studies of underwater UV irradiance to atmospheric and oceanic optical properties have shown that the main environmental parameters controlling absolute levels of UVB (280-320 nm) and DNA-weighted irradiance underwater are solar zenith angle, cloud transmittance, water optical properties, and total ozone. Monthly maps of underwater UV irradiance and DNA-weighted exposure are calculated using monthly mean SeaWiFS chlorophyll and diffuse attenuation coefficient, daily SeaWiFS cloud fraction data, and the TOMS-derived surface UV irradiance daily maps. The results include global maps of monthly average UVB irradiance and DNA-weighted daily exposures at 3 and 10 m and depths where the UVB irradiance and DNA-weighted dose rate at local noon are equal to 10% of their surface values.

These have been compiled to produce the first complete global magnetic field maps of Mars. Crustal magnetization appears dichotomized, with intense magnetization mainly confined to the ancient, heavily cratered highlands in the south. The global distribution of sources is consistent with a reversing dynamo that halted early in Mars evolution. Intense crustal magnetization requires an increased oxidation state relative to mantle-derived rock, consistent with assimilation of an aqueous component at crustal depths.

The Lunar Soil Characterization Consortium, a group of lunar sample and remote sensing scientists, has undertaken the extensive task of characterization of lunar soils, with respect to their mineralogical and chemical makeup. This endeavor is aimed at deciphering the effects of space weathering of soils from the Moon, and these results should apply to other airless bodies. Modal abundances and chemistries of minerals and glasses in the <45 mu m size fractions of nine selected mare soils have been determined, along with the bulk chemistry of each size fraction, and their Is/FeO values. These data can be addressed at http:/web.utk.edu/ approximately pgi/data.html. As grain size decreases, the bulk composition of each size fraction continuously changes and approaches the composition of the agglutinitic glasses. Past dogma had it that the majority of the nanophase Fe (super 0) resides in the agglutinitic glasses. However, as grain size of a soil decreases, the percentage of the total iron present as nanophase-sized Fe (super 0) increases dramatically, while the agglutinitic glass content rises only slightly. This is evidence for a large contribution to the Is/FeO values from surface-correlated nanophase Fe (super 0) , particularly in the <10 mu m size fraction. This surficial nanophase Fe (super 0) is present largely as vapor-deposited patinas on tiie surfaces of almost every particle of the mature soils. It is proposed that these vapor-deposited, nanophase Fe (super 0) -bearing patinas may have far greater effects upon reflectance spectra of mare soils than the agglutinitic Fe (super 0) .

On the lunar nearside, relatively strong anomalies are mapped over the Reiner Gamma Formation on western Oceanus Procellarum and over the Rima Sirsalis rille on the southwestern border of Oceanus Procellarum. The main Rima Sirsalis anomaly does not correlate well with the rille itself but is centered over an Imbrian-aged smooth plains unit interpreted as primary or secondary basin ejecta. The stronger Reiner Gamma anomalies correlate with the locations of both the main Reiner Gamma albedo marking and its northeastward extension. Both the Rima Sirsalis and the Reiner Gamma anomalies are extended in directions approximately radial to the center of the Imbrium basin. This alignment suggests that Imbrium basin ejecta materials (lying in many cases beneath the visible mare surface) are the sources of the nearside anomalies. If so, then the albedo markings associated with the stronger Reiner Gamma anomalies may be consistent with a model involving magnetic shielding of freshly exposed mare materials from the solar wind ion bombardment. Two regions of extensive magnetic anomalies are mapped in regions centered on the Ingenii basin on the south central farside and near the crater Gerasimovic on the southeastern farside. These regions are approximately antipodal to the Imbrium and Crisium basins, respectively. The Imbrium antipode anomaly group is the most areally extensive on the Moon, while the largest anomaly in the Crisium antipode group is the strongest detected by the Lunar Prospector magnetometer. A consideration of the expected antipodal effects of basin-forming impacts as well as a combination of sample data and orbital measurements on the nearside leads to the conclusion that the most probable sources of magnetic anomalies in these two regions are ejecta materials from the respective impacts. In both regions the strongest individual anomalies correlate with swirl-like albedo markings of the Reiner Gamma class visible on available orbital photography.

Between the Imbrium and Nectaris basins, many anomalies correlate with the Cayley and Descartes Formations. Statistical analyses show that the most strongly magnetic nearside terranes are Cayley-type light plains, terra materials, and pre-Imbrian craters. Light plains and terrae include basin impact ejecta as a major component, suggesting that magnetization effects from basin-forming impacts were involved in their formation. The magnetization of pre-Imbrian craters, however, may be evidence of early thermal remanence. Relatively strong, small-scale magnetic anomalies are present over the Reiner Gamma feature on western Oceanus Procellarum and over the Rima Sirsalis rille on the southwestern border of Procellarum. Both Apollo subsatellite and LP data show that the latter anomaly is nearly aligned with the rille, though LP magnetometer and reflectometer data show that the anomaly peak is actually centered over a light plains unit. This anomaly and the Reiner Gamma anomaly are approximately radially aligned with the center of Imbrium, suggesting an association with ejecta from this basin.

We update the Newcombe et al. pioneering study of Hong Kong's urban metabolism in 1971, highlighting trends in resource consumption and waste generation. Per capita food, water and materials consumption have surged since the early 1970s by 20%, 40%, and 149%, respectively. Tremendous pollution has accompanied this growing affluence and materialism, and total air emissions, CO sub(2) outputs, municipal solid wastes, and sewage discharges have risen by 30%, 250%, 245%, and 153%. As a result, systemic overload of land, atmospheric and water systems has occurred. While some strategies to tackle deteriorating environmental quality have succeeded, greater and more far-reaching changes in consumer behavior and government policy are needed if Hong Kong is to achieve its stated goal of becoming "a truly sustainable city" in the 21 super(st) century.

Probabilities of Radiation-Induced Inter- and Intrachromosomal Exchanges and their Dependence on the DNA Content of the Chromosome. Radiat. Res. 156, 603-606 (2001). A biophysical model has been developed that is based on the assumptions that an interphase chromosome occupies a spherical territory and that chromosome exchanges are formed by the misrejoining of two DNA double-strand breaks induced within a defined interaction distance. The model is used to explain the relative frequencies of inter- and intrachromosomal exchanges and the relationship between radiation-induced aberrations in individual chromosomes and the DNA content of the chromosome. Although this simple model predicts a higher ratio of inter- to intrachromosomal exchanges for low-LET radiation than for high-LET radiation, as has been suggested by others, we argue that the comparison of the prediction of the model with experimental results is not straightforward. With the model, we also show that the probability of the formation of interchromosomal exchanges is proportional to the 'surface area' of the chromosome domain plus a correction term. The correction term is small if the interaction distance is less than 1 mu m for both low- and high-LET radiations.

A flow visualization study was conducted on a 28-cm diameter tennis ball model to establish the boundary layer separation locations and Reynolds number effects for both nonspinning and spinning cases. The flow visualization results showed that the separation location on a nonspinning tennis ball occurred relatively early, near the apex, and appeared very similar to a laminar separation in the subcritical Reynolds number regime. Qualitatively, the flow regime (boundary layer separation location) appeared to be independent of Reynolds number in the range, 167 000 < Re < 284 000. Asymmetric boundary layer separation and a deflected wake flow, depicting the Magnus effect, were observed for the spinning ball. In the second phase of the experiments, the drag coefficient of a variety of new and used tennis balls, including prototypes of the recently approved oversized ball, was measured for the case simulating a perfectly flat serve (a serve with zero spin). The measurements were conducted in a Reynolds number range of about 80 000 < Re < 300 000, which corresponds to a velocity range of 19 < U < 70 ms super(-1) (43 < U < 157 mph). The present data, which indicate relatively high drag coefficients for new tennis balls (C sub(D) approximately equal to 0.6-0.7), are compared to existing data for spherical models with varying degrees of surface roughness. The observed (unexpected) behaviour of the tennis ball drag coefficient is explained in terms of a new flow model that includes the drag contribution of the `fuzz' elements.

However, during darkness, or when the satellite's view of the surface is obscured by cloud, snow cover cannot be mapped using MODIS data. We show that during these conditions, it is possible to supplement the MODIS product by mapping the snow cover using passive microwave data from the Special Sensor Microwave Imager (SSM/I), albeit with much poorer resolution. For a 7-day time period in March 1999, a prototype MODIS snow-cover product was compared with a prototype MODIS-SSM/I product for the same area in the mid-western USA. The combined MODIS-SSM/I product mapped 9% more snow cover than the MODIS-only product.

AN - 18264608; 5321758 AB - The 'big-leaf' approach to calculating the carbon balance of plant canopies is evaluated for inclusion in the ETEMA model framework. This approach assumes that canopy carbon fluxes have the same relative responses to the environment as any single leaf, and that the scaling from leaf to canopy is therefore linear. A series of model simulations was performed with two models of leaf photosynthesis, three distributions of canopy nitrogen, and two levels of canopy radiation detail. Leaf- and canopy-level responses to light and nitrogen, both as instantaneous rates and daily integrals, are presented. Observed leaf nitrogen contents of unshaded leaves are over 40% lower than the big-leaf approach requires. Scaling from these leaves to the canopy using the big-leaf approach may underestimate canopy photosynthesis by ~20%. A leaf photosynthesis model that treats within-leaf light extinction displays characteristics that contradict the big-leaf theory. Observed distributions of canopy nitrogen are closer to those required to optimize this model than the homogeneous model used in the big-leaf approach. It is theoretically consistent to use the big-leaf approach with the homogeneous photosynthesis model to estimate canopy carbon fluxes if canopy nitrogen and leaf area are known and if the distribution of nitrogen is assumed optimal. However, real nitrogen profiles are not optimal for this photosynthesis model, and caution is necessary in using the big-leaf approach to scale satellite estimates of leaf physiology to canopies. Accurate prediction of canopy carbon fluxes requires canopy nitrogen, leaf area, declining nitrogen with canopy depth, the heterogeneous model of leaf photosynthesis and the separation of sunlit and shaded leaves. The exact nitrogen profile is not critical, but realistic distributions can be predicted using a simple model of canopy nitrogen allocation.

Similar to the North Pacific tropical cyclone study, mean monthly rainfall within 444 km of the center of the North Atlantic tropical cyclones (i.e., that reached storm stage and greater) was estimated from passive microwave satellite observations during an 11-yr period. These satellite-observed rainfall estimates were used to assess the impact of tropical cyclone rainfall in altering the geographical, seasonal, and interannual distribution of the North Atlantic total rainfall during June-November when tropical cyclones were most abundant. The main results from this study indicate 1) that tropical cyclones contribute, respectively, 4%, 3%, and 4% to the western, eastern, and entire North Atlantic; 2) similar to that observed in the North Pacific, the maximum in North Atlantic tropical cyclone rainfall is approximately 5 degree -10 degree poleward (depending on longitude) of the maximum nontropical cyclone rainfall; 3) tropical cyclones contribute regionally a maximum of 30% of the total rainfall northeast of Puerto Rico, within a region near 15 degree N, 55 degree W, and off the west coast of Africa; 4) there is no lag between the months with maximum tropical cyclone rainfall and nontropical cyclone rainfall in the western North Atlantic, whereas in the eastern North Atlantic, maximum tropical cyclone rainfall precedes maximum nontropical cyclone rainfall; 5) like the North Pacific, North Atlantic tropical cyclones of hurricane intensity generate the greatest amount of rainfall in the higher latitudes; and 6) warm El Nino-Southern Oscillation events inhibit tropical cyclone rainfall.

Measurements with a dual-polarized 19-GHz radiometer reveal a polarization difference of as much as -18 K in the downwelling microwave radiation at 30 degree elevation angle. Averaging all rain observations within 19 months leads to a signal of -6 K. Model calculations covering roughly the same range of weather conditions as that inferred from the meteorological data recorded with the radiometer measurements were carried out with spherical raindrop shape and an oblate particle shape with a fixed horizontal alignment. From the model results, positive polarization difference is expected for spherical particles. This signal was never observed in the recorded data. For oblate drops, the averaged model results lead to a polarization difference of -8 K, which is in reasonable agreement with the long-term averaged observations. Case studies that compare isolated rain events usually lead to a better match of model and observations. However, there are some major discrepancies in some cases. Possible reasons for the remaining differences are the short-term variations in the cloud microphysics for which the model does not correctly account, such as variations in the melting layer, drop oscillations, or variations in the drop size distribution or angular distribution of the drop alignment. Three-dimensional effects are also important when observing small-scale heavy precipitation. Despite remaining small uncertainties, the comparison presents strong evidence that the oblate raindrop shape, with fixed horizontal alignment, is by far the better choice for accurate radiative transfer calculations than is the spherical shape. The omission of this shape effect can cause significant errors when developing remote sensing algorithms based on model results.

Thermocrinis ruber, Thermocrinis sp. strain HI 11/12, Hydrogenobacter thermophilus TK-6, Aquifex pyrophilus, and Aquifex aeolicus all contained glycerol-ether phospholipids as well as acyl glycerides. The n-C sub(20:1) and cy-C sub(21) fatty acids dominated all of the Aquificales, while the alkyl glycerol ethers were mainly C sub(18:0). These Aquificales biomarkers were major constituents of the lipid extracts of two Octopus Spring samples, a biofilm associated with the siliceous vent walls, and the well-known pink streamer community (PSC). Both the biofilm and the PSC contained mono- and dialkyl glycerol ethers in which C sub(18) and C sub(20) alkyl groups were prevalent. Phospholipid fatty acids included both the Aquificales n-C sub(20:1) and cy-C sub(21), plus a series of iso-branched fatty acids (i-C sub(15:0) to i-C sub(21:0)), indicating an additional bacterial component. Biomass and lipids from the PSC were depleted in super(13)C relative to source water CO sub(2) by 10.9 and 17.2ppt, respectively. The C sub(20-21) fatty acids of the PSC were less depleted than the iso-branched fatty acids, 18.4 and 22.6ppt, respectively. The biomass of T. ruber grown on CO sub(2) was depleted in super(13)C by only 3.3ppt relative to C source. In contrast, biomass was depleted by 19.7ppt when formate was the C source. Independent of carbon source, T. ruber lipids were heavier than biomass (+1.3ppt). The depletion in the C sub(20-21) fatty acids from the PSC indicates that Thermocrinis biomass must be similarly depleted and too light to be explained by growth on CO sub(2). Accordingly, Thermocrinis in the PSC is likely to have utilized formate, presumably generated in the spring source region.

Continuous underway measurements allowed simultaneous mapping of the dispersal pattern of riverine organic material and Chl a on the shelf. We used two fluorescence emission ratios to differentiate between riverine and marine COM. The data showed unusually high concentrations of COM offshore. These were attributed to an offshore extension of the Mississippi River plume. Comparisons between in situ Chl a concentrations measured with the SAFIre and Chl a values obtained from the sea-viewing wide field-of-view sensor (SeaWiFS) satellite data using OC4 and MODIS algorithms showed that, although both algorithms overestimated Chl a, MODIS performed better than OC4, particularly in areas with high COM concentrations. Analysis of the relationship between Chl a and COM concentrations within the study area showed regional variability probably caused by differences in river source.

Mounting evidence indicates that conventional linear energy transfer (LET) defined protection quantities (quality factors) may not be appropriate for GCR ions. The available biological data indicates that aluminum alloy structures may generate inherently unhealthy internal spacecraft environments in the thickness range for space applications.

We concluded that an increase in the production of isochromatid breaks is a signature of initial high-LET radiation-induced G2-phase damage. In this paper, we report the repair kinetics of isochromatid breaks induced by high-LET radiation in normal G2-phase human fibroblasts. Exponentially growing human fibroblasts (AG1522) were irradiated with gamma rays or energetic carbon (290 MeV /nucleon), silicon (490 MeV/nucleon), or iron (200 MeV/nucleon) ions. Prematurely condensed chromosomes were induced by calyculin A after different postirradiation incubation times ranging from 0 to 600 min. Chromosomes were stained with Giemsa, and aberrations were scored in cells at G2 phase. G2-phase fragments, the result of the induction of isochromatid breaks, decreased quickly with incubation time. The curve for the kinetics of the rejoining of chromatid-type breaks showed a slight upward curvature with time after exposure to 440 keV/ mu m iron particles, probably due to isochromatid-isochromatid break rejoining. The formation of chromatid exchanges after exposure to high-LET radiation therefore appears to be underestimated, because isochromatid-isochromatid exchanges cannot be detected. Increased induction of isochromatid breaks and rejoining of isochromatid breaks affect the overall kinetics of chromatid-type break rejoining after exposure to high-LET radiation.

The interaction potentials involve a description of the carbon nanotube using Morse, harmonic bending, torsion, and Lennard-Jones potentials. The water is described by the flexible Simple Point Charge (SPC) model by Teleman et al., and the carbon-water interactions include a carbon-oxygen Lennard-Jones potential, and an electrostatic quadrupole moment acting between the carbon atoms and the charge sites of the water. Vibration of the breathing mode of the carbon nanotube in water is inferred from the oscillations in carbon-carbon van der Waals energy, and the inverse proportionality between the radius of the carbon nanotube and the breathing frequency is in good agreement with experimental values. The results indicate, that under the present conditions, the presence of the water has a negligible influence on the breathing frequency. The water at the carbon-water interface is found to have a HOH plane nearly tangential to the interface, and the water radial density profile exhibits the characteristic layering also found in the graphite-water system. The average number of hydrogen bonds decreases from a value of 3.73 in the bulk phase to a value of 2.89 at the carbon-water interface. The inclusion of the carbon quadrupole moment is found to have a negligible influence on the structural properties of the water. Energy changes that occur by the process of introducing a carbon nanotube in water are calculated. The creation of a cavity in the bulk water to accommodate the nanotube constitutes the largest energy contribution. Results include an analysis of surface structure and energy values for planar and for concave cylindrical surfaces of water.

Refinements of this ecosystem model include stand water balance equations, moisture holding and retention capacity for Amazon soils, and addition of a dynamic deforestation sequence to include land use change as a factor in simulations of tropical ecosystem fluxes. Results suggest that model predictions for evapotranspiration and soil water content are consistent with the overall range and seasonal changes in measured values at the two forest sites selected as test cases. The predicted carbon balance from the model implies that relatively undisturbed Amazon forest ecosystems may be large net sinks for atmospheric carbon, with annual net ecosystem production values on the order of 200 g C m super(-2) per year. Measured fluxes of soil N sub(2)O for the two Amazon forests closely match our model prediction for the Par a forest, but not for the Rond o nia site, suggesting that process algorithms controlling nitrogen trace gas fluxes, particularly in relatively sandy tropical soils will require further study. In terms of net ecosystem carbon fluxes during deforestation and for 2 years afterward, the model predicts that these sites switch from being a net sink for carbon to a substantial source following the large loss of biomass from simulated burning. During crop regrowth simulation in the first year after deforestation, the net source of carbon to the atmosphere is nearly 1.6 kg C m super(-2) per year, a flux magnitude roughly equivalent to 10 years of undisturbed CO sub(2) sink fluxes in the Amazon forest. Compared to the primary forest that was cut and burned, predicted changes in soil nitrogen cycling lead to a doubling in annual emissions of N sub(2)O gas during the first year following deforestation, with lower emissions thereafter. Implications for scaling up these model predictions to the Amazon forest region are discussed with reference to necessary improvements in land cover, land use, and soils classifications for the area.

AN - 72428090; 11842852 AB - Objective. To demonstrate that the recycled liquid, which originated from lettuce inedible biomass degraded by fixed microorganism (correction of microorgannism) and enzyme, can be used as a nutrient solution for lettuce hydroponic cultivation. Method. After biologically degrading the weighted, oven-dried and milled leaves and roots of lettuce in a biological reactor under aerobic condition, the original effluent and its supplemented effluent were used as nutrients for lettuce hydroponic cultivation. Result. The average dried weight (ADW) of lettuce from the original effluent group was approximately half of that from the control group, and the ADW from supplemented effluent group was about equal to that from the control group; some qualities of the lettuce such as a relatively lower content of NO3- from both the original effluent group and the supplemented effluent one improved, and some of those such as a relatively higher content of NO2- dropped. Conclusion. The biologically-degraded effluent was able to be used as nutrient solution for lettuce hydroponic cultivation, although the effects of the inorganic ion-supplemented effluent were much better; the plants of lettuce from the biologically-degraded effluent were safely edible.

AN - 71354976; 12194183 AB - One major obstacle to human space exploration is the possible limitations imposed by the adverse effects of long-term exposure to the space environment. Even before human spaceflight began, the potentially brief exposure of astronauts to the very intense random solar energetic particle (SEP) events was of great concern. A new challenge appears in deep space exploration from exposure to the low-intensity heavy-ion flux of the galactic cosmic rays (GCR) since the missions are of long duration and the accumulated exposures can be high. Since aluminum (traditionally used in spacecraft to avoid potential radiation risks) leads to prohibitively expensive mission launch costs, alternative materials need to be explored. An overview of the materials related issues and their impact on human space exploration will be given. Published by Elsevier Science Ltd.

AN - 71323634; 12101354 AB - To investigate the effects of cosmic radiation and microgravity on embryogenesis and organogenesis in Bombyx eggs, two different stages of eggs, the early stage after oviposition and the diapause-terminated eggs, were loaded on the US Space Shuttle/Atlantis (STS-84) for a 9 day flight. More than 85% of the early stage eggs hatched in the flight sample and the ground control. In the diapause-terminated eggs, the percentage of unhatched eggs were 43% in the ground control and 56% in the flight sample. In these eggs, uncompleted embryonic reversal was observed two-fold higher percentage in the flight sample than in the ground control. The incidence of abnormality such as the larvae with segmental fusion and the appearance of abnormal crescent marking in the flight sample was significantly higher than that in the ground control. This was also observed in the 1st and 2nd filial generation of the flight sample. From these results, unsuccessful blastokinesis and the abnormal appearance was discussed in relation to cosmic radiation and microgravity.

AN - 71314653; 12101350 AB - To determine the effects of space radiation on human health for long-term stays in space, we performed 21 space experiments on radiation biology. Two main characteristics of space are microgravity and space radiation that consists of low dose, chronic exposure at low dose-rates, and heavy particles. Through space experiments, we demonstrated the formation of DNA strand breaks, induced mutations, abnormal cell differentiation and the inducible gene expression of a tumor suppressor gene product, p53, in various kinds of organisms. In addition, we investigated the influence of microgravity on radiation-induced biological effects in in vitro biochemical reaction systems and in vivo cell culture systems of bacteria and lower eukaryotes. We review here the importance of radiation biology studies on space radiation from the viewpoints of human health and biological evolution, from the beginning of life until today, in the context of environmental genotoxic radiation.

Importance of Centrifuge Facility in the study of biological effect by space radiation]. AN - 71313998; 11997596 AB - In microgravity, astronauts were constantly exposed to space radiation containing various kinds of radiation with a low-dose rate during long-term stays in space. It is very difficult to define the relative biological effectiveness (RBE) of space radiation under microgravity. In order to understand correct the RBE of space radiation, therefore, utilization of Centrifuge Facility is desired as a control experiment at orbit for removing other factors such as microgravity except space radiation. Here, we summarized the importance of Centrifuge Facility in the study of biological effect of space radiation.

AN - 71313427; 11997634 AB - As the model we proposed last year was contradictory to experimental data, we revised again the models for mixed irradiation by Zaider and Rossi and by Suzuki, substituting a 'reciprocal-time' pattern of repair function for a first-order one in reduction and interaction factors of the models, although we used a second order repair function last year. The reduction factor, which reduces the contribution of the square of a dose to cell killing in the models, and the interaction factor, which also reduces the contribution of the interaction of two or more doses of different types of radiation, were formulated by using the 'reciprocal-time' pattern of repair function. These newly modified models for mixed irradiation could express or predict cell survival more accurately than the older ones, especially when irradiation is prolonged at low dose rates. We present survival curves of cells calculated from the newly and the older models of assumptive simultaneous mixed irradiation with two or three types of radiation.

This is one of the few rare basaltic eucrites whose (super 39) Ar- (super 40) Ar age has not been reset during impact bombardment on the HED parent body 1-5 GPa after the reheating event. EET90020 seems to have experienced the following thermal history; (1) crystallization during rapid cooling near the surface; (2) some brecciation by impact; (3) thermal metamorphism that produced type 5 pyroxene; and (4) short reheating that caused partial melting and rapid cooling. (super 39) Ar- (super 40) Ar measurements show a relatively flat pattern and an age of 4.49+ or -0.01 Ga, which is consistent with rapid cooling from high temperature (event 4). Resetting of the Sm-Nd ages at 4.51+ or -0.04 Ga appears to be closely related to the remelting of Ca-phosphates. Rb-Sr data suggest Rb-loss from tridymite during partial melting. The resetting of the Mn-Cr age may have been related to the formation of Cr-ulvospinels (event 4). We suggest that all these ages were reset by partial melting (event 4). We further suggest that the partial melting event (event 4) that reset the ages approximately 4.50 Ga ago was caused by an impact into EET90020 which was part of the hot crust of 4Vesta and resulted in an increase in the temperature from the ambient temperature of approximately 870 degrees C to above the subsolidus temperature of eucrites of approximately 1060 degrees C.

The EMD+HHT method provides a powerful tool for signal processing to identify nonlinear and nonstationary data. Based on the decomposed ground-motion signal, the absolute input energy of each decomposed wave was studied (the fling step [pulselike wave] can be separated from the recorded near-fault ground motion). Through application of the EMD+HHT method to building and bridge seismic response data, the time-varying system natural frequency and damping ratio can also be estimated. Damage identification from seismic response data of buildings and bridges, particularly from the Chi-Chi earthquake data, is also described.

The EMD method decomposes any data into a finite number of intrinsic mode function (IMF) components with time-variable amplitudes and frequencies. This decomposition is nearly orthogonal and totally adaptive. With the decomposition, a Hilbert, rather than Fourier, transform is applied to each IMF component, which gives each component instantaneous frequency and energy density. This approach is totally new, and it is different from any of the existing methods: it uses differentiation to define the frequency rather than the traditional convolution computation; thus, it gives the instantaneous frequency and energy density. The greatest advantage of the new approach is that it is the only spectral analysis method applicable to nonstationary and nonlinear data. To illustrate the capability of his new method, we have applied it to the earthquake record from station TCU129, at Chi-Chi, Taiwan, collected during the 21 September 1999 earthquake. The same record is also analyzed with Fourier analysis, wavelet transform, and response spectrum analysis. Comparisons among the different analysis methods indicate that the Hilbert spectral analysis gives the most detailed information in a time-frequency-energy presentation. It also emphasizes the potentially damage-causing low-frequency energy in the earthquake signal missed by all the other methods.

Sulfate veins were first described in the Orgueil meteorite in 1961, almost one century after its fall. However, we have observed such veins to form easily during typical sample storage. We suggest that all CI1 sulfate veins formed during the terrestrial residence of these heavily brecciated, porous stones. Reacting with atmospheric water, sulfates originally present in the meteorites dissolved and remobilized, and/or sulfides oxidised, filling the many open spaces offered to them by the very porous rock. Sulfate veins in CI1 chondrites can no longer be used as evidence of a late-stage oxidation event in the CI1 parent body, or of centimeter-scale fluid transport on the parent asteroid.

The selected strains reflect the phylogenetic and physiologic diversity of presently known sulfate reducers and were isolated from a broad range of natural marine and freshwater habitats. Experimental conditions were designed to achieve optimum growth conditions with respect to electron donors, salinity, temperature, and pH. Under these optimized conditions, experimental fractionation factors ranged from 2.0 per mil to 42.0 per mil. Salinity, incubation temperature, pH, and phylogeny had no systematic effect on the sulfur isotope fractionation. There was no correlation between isotope fractionation and sulfate reduction rate. The type of dissimilatory bisulfite reductase also had no effect on fractionation. Sulfate reducers that oxidized the carbon source completely to carbon dioxide showed greater fractionations than sulfate reducers where acetate is the final product of carbon oxidation. Different metabolic pathways and variable regulation of sulfate transport across the cell membrane all potentially affect isotope fractionation. Previous models that explained fractionation only in terms of sulfate reduction rates appear to be oversimplifying. The species-specific physiology of each sulfate reducer needs to be taken into account to understand the regulation of sulfur isotope fractionation during dissimilatory sulfate reduction.

Sulfate-reducing bacteria prefer to reduce sulfate containing (super 32) S compared to sulfate containing (super 34) S, and therefore sedimentary sulfides depleted in (super 32) S were likely formed by sulfate-reducing bacteria. In modern sediments and in sediments deposited through the Phanerozoic, sulfides are however, generally depleted in (super 32) S by more than can be explained by sulfate reduction alone. Additional fractionation to that of sulfate reduction must occur in these sediments, probably during the reoxidation of sulfide to sulfate. The oxidative part of the sulfur cycle is very complex and generally no isotope fractionations are associated with the direct biological and chemical oxidation of sulfide to sulfate. The only processes known to deplete sedimentary sulfide in (super 32) S during the oxidative part of the sulfur cycle are the microbial disproportionation of elemental sulfur, thiosulfate and sulfite. The disproportionation processes might, therefore, be important in Phanerozoic sediments. In the Precambrian sedimentary sulfides are not depleted by more than about 45 per mil, which is also the maximum fractionation yet observed during the microbial reduction of sulfate. Additional isotope fractionation during the oxidative part of the sulfur cycle was probably not important in the Precambrian. I will discuss which processes within the sulfur cycle might dominate in Phanerozoic sediments and in the Precambrian. Sedimentary sulfides depleted in (super 32) S by more than 45 per mil are first encountered in sediments around 0.8 billion years old. This increase in fractionation might correlate with an increase in the O (sub 2) concentration in the atmosphere at this time.

This paper discusses the function of the MOLA instrument and the acquisition, processing, and correction of observations to produce global data sets. The altimeter measurements have been converted to both gridded and spherical harmonic models for the topography and shape of Mars that have vertical and radial accuracies of approximately 1 m with respect to the planet's center of mass. The current global topographic grid has a resolution of 1/64 degrees in latitude X 1/32 degrees in longitude (1 X 2 km (super 2) at the equator). Reconstruction of the locations of incident laser pulses on the Martian surface appears to be at the 100-m spatial accuracy level and results in 2 orders of magnitude improvement in the global geodetic grid of Mars. Global maps of optical pulse width indicative of 100-m-scale surface roughness and 1.064-mu m reflectivity with an accuracy of 5% have also been obtained.

Perturbations of the 3.6-cm lambda radio path by the atmosphere during periods of atmospheric occultation provide the vertical temperature-pressure structure T[p(r)] to accuracies at the surface of Delta T nearly equal 0.4 K and Delta p nearly equal 2 Pa, and approximately 10 K and approximately 0.6 Pa at altitudes of 40-50 km; the error in radius is Delta r nearly equal 1 m at all levels. Accurate knowledge of the radius permits fixing of the T-p structure to the geopotential and use of the gradient wind equation to calculate components of the wind. Systematic sampling of the atmosphere in combination with the accuracy of the MGS radio system supports studies of the large-scale dynamics of the atmosphere, including seasonal variations of the atmospheric fields and embedded waves such as Kelvin and Rossby waves. Terminator region ionospheric electron density profiles are obtained successfully much of the time but on occasion are undetectable with the MGS system. Two-way radio tracking of MGS with uncertainties in the line-of-sight velocity of several to tens of mu m s (super -1) and less supports solution for spherical harmonic models of the gravity field of order and degree in the range of 75X75, although the degree and order of meaningful terms is limited by the approximately 400 km spacecraft altitude to approximately 62X62, corresponding to a resolution of a few degrees of arc on the surface. This resolution of gravity is sufficient to support geophysical studies of the planet's interior structure and history. Additional radio science investigations include the search for gravitational radiation and observation of very low grazing angle forward scattering by the surface of Mars.

We find that for pure liquid water, there are five "favorable" regions where these requirements are satisfied: between 0 degrees and 30 degrees N in the plains of Amazonis, Arabia, and Elysium; and in the Southern Hemisphere impact basins of Hellas and Argyre. The combined area of these regions represents 29% of the planet's surface area. In the Amazonis region these requirements are satisfied for a total integrated time of 37 sols each Martian year. In the Hellas basin the number of degree days above zero is 70, which is well above those experienced in the dry valley lake region of Antarctica. These regions are remarkably well correlated with the location of Amazonian paleolakes mapped by Cabrol and Grin [2000] but are poorly correlated with the seepage gullies found by Malin and Edgett [2000]. In both instances, obliquity variations may play a role. For brine solutions the favorable regions expand and could potentially include most of the planet for highly concentrated solutions. Whether liquid water ever forms in these regions depends on the availability of ice and heat and on the evaporation rate. The latter is poorly understood for low-pressure CO (sub 2) environments but is likely to be so high that melting occurs rarely, if at all. However, even rare events of liquid water formation would be significant since they would dominate the chemistry of the soil and would have biological implications as well. It is therefore worth reassessing the potential for liquid water formation on present day Mars, particularly in light of recent Mars Global Surveyor observations.

The Sinus Meridiani material is an in-place, rock stratigraphic sedimentary unit characterized by smooth, friable layers composed primarily of basaltic sediments with approximately 10-15% crystalline gray hematite. This unit has outliers to the north that appear to have formed by stripping and removal. The hematite within Aram Chaos occurs in a sedimentary layer within a closed basin that was likely formed during the basin infilling and predates the formation of nearby chaos and outflow terrains. This unit appears to be exposed by erosion and may be more extensive beneath the surface. The Valles Marineris occurrences are closely associated with the interior layered deposits and may be in place within the layers or eroded sediments. Overall, crystalline gray hematite is extremely uncommon at the surface, yet in all observed locations it is closely associated with layered, sedimentary units. Here we argue that these hematite deposits have formed by a process involving chemical precipitation from aqueous fluids, under either ambient or hydrothermal conditions. Thus the TES mineralogie data provide evidence that liquid water has been stable at or near the surface, probably for millions of years by analogy with terrestrial iron formations, in specific locations on early Mars.

An extensive system of graben cuts across Alba Patera, extending from Ceraunius Fossae to the south to Tantalus Fossae to the northeast. In the vicinity of the edifice, the otherwise generally north-south orientations of these graben are deflected to circumferential directions. MOLA topography reveals that the circumferential graben are located well up the flanks of Alba Patera. Both the type (extensional) and location (midflank) of faulting on Alba Patera are inconsistent with the state of stress predicted for purely surface-loaded flexure models. To constrain the conditions governing the evolution of Alba Patera, we employ finite element models for the volcano and lithospheric stress field under a combination of loading mechanisms. Buoyant sublithospheric loads (representing underplated magma, low-density mantle residuum, or dynamic support from mantle convection) and intralithospheric displacements (representing sills "trapped" by horizontal compressive stresses in the upper lithosphere) can generate the observed midflank slope breaks and circumferential extensional fault zones at radial distances comparable to that of the subsurface load's characteristic radial extent. Both mechanisms moderate stresses in the upper lithosphere in favor of continued magma ascent. However, bottom loading requires a disk-like load geometry and an elastic lithosphere thickness T (sub e) sufficiently small to allow the load's shape to be apparent in the surface deformation (T (sub e) < or = 32 km). Such low T (sub e) is inconsistent with Mars Global Surveyor (MGS) gravity and topography data. In contrast, intralithospheric sill complexes can produce the observed topography and faulting at T (sub e) values consistent with those inferred from gravity and topography (50 < or = T (sub e) < or = 100 km). For these conditions, principal stress orientations on the lower flanks are also consistent with the orientations of lower-flank graben, provided that faulting was induced by dike intrusion or tensile failure rather than shear failure.

The fundamental objectives of this investigation were to (1) establish the nature of the magnetic field of Mars; (2) develop appropriate models for its representation; and (3) map the Martian crustal remanent field (if one existed) to a resolution consistent with the spacecraft orbit altitude and ground track separation. Important and complementary objectives were the study of the interaction of Mars with the solar wind and of its ionosphere. The instrumentation is a synergistic combination of a twin-triaxial, fluxgate magnetometer system and an electron reflectometer. The twin-magnetometer system allows the real-time detection of spacecraft-generated fields, while the electron reflectometer adds remote magnetic field sensing capabilities as well as information about the local electron population. After Mars orbit injection in September 1997 and through the aerobraking (AB) and science-phasing orbits (SPO) that followed, observations were acquired from more than 1000 elliptical orbits with periapses ranging from 85 to 170 km above Mars' surface. Following injection into the final approximately 400 km altitude circular-mapping orbit, data have been acquired from more than 6000 orbits in the fixed 0200-1400 local time plane. Major results obtained so far by the Magnetometer/Electron Reflectometer (MAG/ER) investigation in the course of the mission include (1) the determination that Mars does not currently possess a magnetic field of internal origin (dynamo), (2) the discovery of linear, strongly magnetized regions in its crust, closely associated with the ancient, cratered terrain of the highlands in the southern hemisphere, and (3) multiple magnetic "cusps" that connect the crustal magnetic sources to the Martian tail and shocked solar wind plasma. The solar wind interaction with Mars is therefore similar in many ways to that at Venus and at an active comet, primarily an ionospheric/atmospheric interaction. A comet-like "magnetic pileup" region and boundary develop that stand off the solar wind, and mass loading by pickup ions of planetary origin plays an important role in defining interaction regions and overall geometry. This paper focuses primarily on the results obtained by the magnetometer (MAG) portion of the investigation during the MGS aerobraking, science-phasing, and mapping orbits. A companion paper on this issue summarizes the results obtained from the Electron Reflectometer (ER) sensor. Copyright 2001 by the American Geophysical Union.

Data from the Mars Global Surveyor Thermal Emission Spectrometer (TES) demonstrate that White Rock is not anomalously bright relative to other Martian bright regions, reducing the significance of its albedo and weakening the analogy to terrestrial playas. Its thermal inertia value indicates that it is not mantled by a layer of loose dust, nor is it bedrock. The thermal infrared spectrum of White Rock shows no obvious features of carbonates or sulfates and is, in fact, spectrally flat. Images from the Mars Orbiter Camera show that the White Rock massifs are consolidated enough to retain slopes and allow the passage of saltating grains over their surfaces. Material appears to be shed from the massifs and is concentrated at the crests of nearby bedforms. One explanation for these observations is that White Rock is an eroded accumulation of compacted or weakly cemented aeolian sediment. Copyright 2001 by the American Geophysical Union.

These objectives are met using an infrared (5.8- to 50-mu m) interferometric spectrometer, along with broadband thermal (5.1- to 150-mu m) and visible/near-IR (0.3- to 2.9-mu m) radiometers. The MGS TES instrument weighs 14.47 kg, consumes 10.6 W when operating, and is 23.6 X 35.5 X 40.0 cm in size. The TES data are calibrated to a 1-sigma precision of 2.5 (super -6) X 10 (super -8) W cm (super -2) sr (super -1) /cm (super -1) , 1.6 X 10 (super -6) W cm (super -2) sr (super -1) , and approximately 0.5 K in the spectrometer, visible/near-IR bolometer, and IR bolometer, respectively. These instrument subsections are calibrated to an absolute accuracy of approximately 4 X 10 (super -8) W cm (super -2) sr (super -1) /cm (super -1) (0.5 K at 280 K), 1-2%, and approximately 1-2 K, respectively. Global mapping of surface mineralogy at a spatial resolution of 3 km has shown the following: (1) The mineralogic composition of dark regions varies from basaltic, primarily plagioclase feldspar and clinopyroxene, in the ancient, southern highlands to andesitic, dominated by plagioclase feldspar and volcanic glass, in the younger northern plains. (2) Aqueous mineralization has produced gray, crystalline hematite in limited regions under ambient or hydrothermal conditions; these deposits are interpreted to be in-place sedimentary rock formations and indicate that liquid water was stable near the surface for a long period of time. (3) There is no evidence for large-scale (tens of kilometers) occurrences of moderate-grained (>50-mu m) carbonates exposed at the surface at a detection limit of approximately 10%. (4) Unweathered volcanic minerals dominate the spectral properties of dark regions, and weathering products, such as clays, have not been observed anywhere above a detection limit of approximately 10%; this lack of evidence for chemical weathering indicates a geologic history dominated by a cold, dry climate in which mechanical, rather than chemical, weathering was the significant form of erosion and sediment production. (5) There is no conclusive evidence for sulfate minerals at a detection limit of approximately 15%. The polar region has been studied with the following major conclusions: (1) Condensed CO (sub 2) has three distinct end-members, from fine-grained crystals to slab ice. (2) The growth and retreat of the polar caps observed by MGS is virtually the same as observed by Viking 12 Martian years ago. (3) Unique regions have been identified that appear to differ primarily in the grain size of CO (sub 2) ; one south polar region appears to remain as black slab CO (sub 2) ice throughout its sublimation. (4) Regional atmospheric dust is common in localized and regional dust storms around the margin and interior of the southern cap. Analysis of the thermophysical properties of the surface shows that (1) the spatial pattern of albedo has changed since Viking observations, (2) a unique cluster of surface materials with intermediate inertia and albedo occurs that is distinct from the previously identified low-inertia/bright and high-inertia/dark surfaces, and (3) localized patches of high-inertia material have been found in topographic lows and may have been formed by a unique set of aeolian, fluvial, or erosional processes or may be exposed bedrock.

These measurements were made from the observed orbital decay of the Mars Global Surveyor (MGS) spacecraft during its Science Phasing Orbits (SPO) (April to September 1998) using X band Doppler tracking observations. The densities that we retrieve are comparable to model values given by Culp and Stewart [1984], Stewart [1987], Mars-GRAM 3.7 [Justus et al., 1996], and recent Mars Thermospheric Global Circulation Model (MTGCM) simulations [Bougher et al., 2000]. However, the SPO period can be divided into two time periods (separated at L (sub s ) nearly equal 355 degrees approximately 0 degrees ) that are characterized by significantly different orbit-to-orbit variability that is not predicted by these earlier models. The first time period corresponds to the time during which the MGS orbit perifocus moved toward the north pole while the local solar time was 1000-1100; during this period, orbit-to-orbit variability is 50-70%, and our average measured density at 175 km is 0.018 + or - 0.007 kg km (super -3) (between 67 degrees and 72 degrees N and L (sub s ) =315 degrees to 320 degrees ). The second time period corresponds to the time during which the orbit perifocus moved south from the north pole and the local time was 1700-1730; during this period, orbit-to-orbit variability is 40-20%, and our average measured density at 175 km is 0.024 + or - 0.004 kg km (super -3) (between 62 degrees and 69 degrees N and L (sub s ) =17 degrees to 28 degrees ). For both time periods the observed latitudinal gradient of density on a constant altitude surface exhibited a factor of 3-4 decrease between 60 degrees and 90 degrees N. This gradient is comparable to that expected by the polar vortex (high-latitude wind) effect modeled by the MTGCM for solar medium conditions at southern summer solstice [Bougher et al., 2000]. A southern hemisphere dust storm that the MGS Thermal Emission Spectrometer (TES) observed at L (sub s ) =309 degrees is distinguishable in our data set as a 100% rise in density at 180 km above the 70 degrees northern latitudes 7 days later (L (sub s ) =313 degrees ).

These data can be used in conjunction with magnetometer data to probe Mars' crustal magnetic field and to study Mars' ionosphere and solar wind interaction. During aerobraking, ionospheric measurements were obtained in the northern hemisphere at high solar zenith angles (SZAs, typically approximately 78 degrees ). The ionopause was crossed at altitudes ranging from 180 km to over 800 km, with a median of 380 km. The 400-km-altitude polar mapping orbit allows observations at SZAs from 25 degrees to 155 degrees in both the northern and southern hemispheres. The near-planet ionosphere and magnetotail structure of the night hemisphere is dominated by the presence of intense crustal magnetic fields, which can exceed 200 nT at the spacecraft altitude. Closed field lines anchored to highly elongated crustal sources form "magnetic cylinders," which exclude solar wind plasma traveling up the magnetotail. When the spacecraft passes through one of these structures, the ER count rate falls to the instrumental background, representing an electron flux drop of at least two orders of magnitude. A map of these flux dropouts in longitude and latitude closely resembles a map of the crustal magnetic sources. When the crustal magnetic cylinders rotate into sunlight, they fill with ionospheric plasma. Since many of these crustal fields are locally strong enough to stand off the solar wind to altitudes well above 400 km, the ionosphere can extend much higher than would otherwise be possible in the absence of crustal fields. Even weak crustal fields may locally bias the median ionopause altitude, which provides an indirect method of detecting crustal fields using ER observations.

Combined nadir- and limb-viewing spectra allow global monitoring of the atmosphere up to 0.01 mbar (65 km). We report here on the atmospheric thermal structure and the distribution of aerosols as observed thus far during the mapping phase of the Mars Global Surveyor mission. Zonal and temporal mean cross sections are used to examine the seasonal evolution of atmospheric temperatures and zonal winds during a period extending from northern hemisphere midsummer through vernal equinox (L (sub s ) = 104 degrees -360 degrees ). Temperature maps at selected pressure levels provide a characterization of planetary-scale waves. Retrieved atmospheric infrared dust opacity maps show the formation and evolution of regional dust storms during southern hemisphere summer. Response of the atmospheric thermal structure to the changing dust loading is observed. Maps of water-ice clouds as viewed in the thermal infrared are presented along with seasonal trends of infrared water-ice opacity. Uses of these observations for diagnostic studies of the dynamics of the atmosphere are discussed. Copyright 2001 by the American Geophysical Union.

During the mapping mission, MGS was located in a near-polar (92.9 degrees inclination) and near-circular orbit at a mean altitude of 400 km. The tracking data from this orbit provide a detailed, global, and high resolution view of the gravity field of Mars. Mars gravity solutions are stable to 60 X 60 even without application of a Kaula power law constraint. The Valles Marineris is resolved distinctly with lows reaching -450 mGals. Olympus Mons and its aureole are both separately resolved, and the volcano has a peak anomaly of 2950 mGals. The global correlation of the GMM-2B gravity coefficients with MOLA-derived topography is 0.78 through degree 60, and the correlation remains above 0.6 through degree 62. The global gravity anomaly error predicted from the GMM-2B error covariance through 60 X 60 is 11 mGal. The global geoid error from GMM-2B through 60 X 60 is 1.8 m. MGS orbit quality using GMM-2B, as measured by overlapping orbital arcs, is 1 m in the radial direction and 10 m in total position. Copyright 2001 by the American Geophysical Union.

The accuracy of the profiles depends on knowledge of the spacecraft position, orientation, and observation time, which are subject to errors. We model these errors via the analysis of over 24 million altimetric crossovers. A quasiperiodic, once per revolution adjustment of the ground tracks as a function of time in three locally orthogonal directions minimizes the altimetric residuals via least-squares. Using a sparse matrix technique, computational effort scales linearly with the number of crossovers and only marginally with the number of parameters. Orbital errors mainly result from poor modeling of spacecraft thrusting events in the absence of tracking. Seasonal effects, likely due to changing thermal environment, as well as residual miscalibrations, are evident in the pointing solutions. Incorporating multiple parameters per revolution significantly improves crossover residuals, and resolves pointing aberrations during orbital transitions from night to day. Altimetry from the adjusted tracks generates a topographic model whose accuracy is typically better than l m vertically with respect to the center of mass of Mars. The centroid position of each MOLA shot is typically accurate to approximately 100 m horizontally. Terrain models from accurately located lidar data can be gradient-shaded to illuminate geological structures with 1 in 1000 slopes that are invisible to cameras. Temporal changes in elevation (e.g., frost deposition/ablation) at decimeter levels may also be assessed using crossovers, but results must be interpreted with caution due to uncertainties in range walk correction.

Assuming a constant, but unknown, number concentration with height, the algorithm retrieves the number concentration and vertical profiles of liquid water content and particle effective radius. A novel aspect of the retrieval is that it depends upon an estimated particle median radius vertical profile that is derived from a statistical model that relates size to variations in particle vertical velocity; the model posits that the median particle radius is proportional to the fourth root of the particle velocity variance if the radii of particles in a parcel of zero vertical velocity is neglected. The performance of the retrieval is evaluated using data from two stratus case study days 1.5 and 8.0 h in temporal extent. Aircraft in situ microphysical measurements were available on one of the two days, and the retrieved number concentrations and effective radii are consistent with them. The retrieved liquid water content and effective radius increase with height for both stratus cases, which agree with earlier studies. Error analyses suggest that the error in the liquid water content vanishes, and the magnitudes of the fractional error in the effective radius and shortwave extinction coefficient computed from retrieved cloud particle size distributions are half of the magnitudes of the fractional error in the estimated cloud particle median radius if the fractional error in the median radius is constant with height.

Examples of ETM+ data illustrate its ability to satisfy major scientific needs in the glaciological subdisciplines of sea-ice, glacier, ice-cap, and ice-sheet research with high-resolution optical satellite imagery. Examples shown include use as proxy ground-truth, positioning glacier termini and snowlines, and determining snow facies boundaries. The additional ETM+ panchromatic band, at a higher spatial resolution of 15 m, improves the spatial accuracy of these applications. The glaciological aspects of the Landsat-7 Long-Term Acquisition Plan are discussed to show how the timing and location of the image acquisitions will generate a cryospheric data set of unprecedented utility for future research.

Global K sub(u)-band data were acquired by the National Aeronautics and Space Administration (NASA) Scatterometer (NSCAT) operated on the Advanced Earth Observing Satellite (ADEOS) from September 1996 to June 1997. NSCAT backscatter patterns over the northern hemisphere reveals boundaries between different snow classes, defined by the Cold Regions Research and Engineering Laboratory (CRREL), Hanover, NH, snow classification system at different times of the snow season. We show the evolution-of the backscatter signature throughout the entire seasonal snow cycle. Within the snow extent determined by the National Oceanic and Atmospheric Administration (NOAA), Washington, DC, and Climate Prediction Center (CPC), operational snow product, K sub(u)-band backscatter data expose detailed features and rapid changes as observed in in-situ snow depth data from surface weather stations in U.S., Canada, and Russia. Sensitivity of K sub(u)-band backscatter to snow conditions is illustrated with the dramatic change over the U.S. northern plains and the Canadian prairie region corresponding to the snow event leading to the 1997 Flood of the Century. We discuss snow field experiments and data analysis plan to understand snow scattering mechanisms, to interpret snow backscatter, and to derive its relationship with snow physical parameters. In view of current and future satellite K sub(u)-band scatterometers, the development of algorithms for quantitative snow cover monitoring is pertinent.

ASAR will be operated at C band with multiple polarizations and multiple incidence angles. To evaluate the use of future ASAR data for Arctic sea ice mapping, we carry out a study of multiple polarization C-band SAR signatures of various sea ice types. We present polarimetric SAR data acquired over sea ice acquired by the Jet Propulsion Laboratory (JPL) polarimetric AIRSAR system on the NASA DC-8 aircraft over sea ice regions in the Beaufort Sea and the Bering Sea. We use a physical sea ice model to obtain and study polarimetric scattering signatures of sea ice under various conditions. We also compare sea ice signatures with backscatter of ocean surface at different wind speeds using an empirical C-band ocean wind geophysical model function. We present backscatter signatures for ENVISAT ASAR single polarization modes and alternating polarization modes over all swaths. We find that different polarization combinations in various ENVISAT ASAR image modes at different incidence angle ranges need to be selected to obtain more accurate or more robust results for sea ice mapping. In the wide swath mode, ENVISAT ASAR polarization can be chosen to measure either horizontal or vertical backscatter exclusively. For light wind conditions near a sea ice edge, horizontal backscatter is better to distinguish between first-year ice (excluding young ice) and open ocean surface at large incidence angles. For high winds, vertical backscatter is better in identifying most sea ice types (except multi-year ice at large incidence angles) from open water over a large range of incidence angles. We also investigate diurnal effects to determine the impact on sea ice backscatter acquired at different times of the day. Results show that diurnal effects on first-year ice are significant so that SAR data collected over sun-synchronous ascending orbits and descending orbits in daytimes and nighttimes need to be analyzed separately to obtain consistent sea ice mapping results. This study also provides useful information for the application of the future RADARSAT-2 multi-polarization SAR to sea ice mapping.Original Abstract: Le capteur radar ASAR (Advanced Synthetic Aperture Radar) est prevu pour lancement sur le satellite ENVISAT en 2001. Le capteur ASAR utilisera la bande C avec des polarisations multiples et des angles d'incidence multiples. Pour evaluer l'utilisation des donnees futures ASAR dans le contexte de la cartographie de la glace de mer en Arctique, nous menons une etude des signatures multi-polarisations RSO en bande C de differents types de glace de mer. Nous presentons des donnees polarimetriques RSO acquises au-dessus de glace de mer au moyen du systeme polarimetrique AIRSAR du JPL (Jet Propulsion Laboratory) a bord de l'appareil DC-8 de la NASA au-dessus de regions recouvertes de glace de mer dans la mer de Beaufort et de Bering. Nous utilisons un modele physique de glace de mer pour obtenir et etudier les signatures de retrodiffusion polarimetrique de la glace de mer dans des conditions diverses. Nous comparons egalement les signatures de la glace de mer avec la retrodiffusion de la surface oceanique selon differentes velocites de vent utilisant une fonction empirique d'un modele geophysique de vent oceanique en bande C. Nous presentons des signatures de retrodiffusion ASAR d'ENVISAT pour les modes en polarisation simple et les modes en polarisation alternante a travers tous les faisceaux. Nous observons qu'il est necessaire de selectionner differentes combinaisons de polarisations dans differents modes image ASAR d'ENVISAT selon differents angles d'incidence pour obtenir des resultats plus precis ou plus robustes dans le contexte de la cartographie de la glace de mer. Dans le cas du mode a faisceau large, on peut choisir la polarisation ASAR d'ENVISAT pour mesurer exclusivement soit la retrodiffusion horizontale ou verticale. Dans des conditions de vent leger pres d'une lisiere de glace de mer, la retrodiffusion horizontale est meilleure pour distinguer entre la glace de premiere annee (a l'exclusion de la jeune glace) et une surface oceanique libre a des grands angles d'incidence. Dans des conditions de vent fort, la retrodiffusion verticale est meilleure pour l'identification de la plupart des types de glace de mer (a l'exception de la glace de plusieurs annees a des grands angles d'incidence) relativement a l'eau libre pour une variete d'angles d'incidence. Nous etudions aussi les effets diurnes pour determiner leur impact sur la retrodiffusion de la glace de mer acquise a differentes heures du jour. Les resultats montrent que les effets diurnes sur la glace de premiere annee sont significatifs si bien que les donnees RSO acquises le jour et la nuit durant les orbites heliosynchrones ascendantes et descendantes doivent etre analysees separement pour obtenir des resultats coherents dans la cartographie de la glace de mer. Cette etude apporte aussi une information utile dans le contexte de l'application des donnees RSO RADARSAT-2 multi-polarisations a la cartographie de la glace de mer.

An approach that simultaneously estimates the geometric and dynamic parameters of the orbit andlaser range measurement model by a combined reduction of both spacecraft tracking and laseraltimeter surface range residuals is applied to produce improved pointing, orbit and range bias solutionsand therefore improved geolocation. The data acquired by the Shuttle Laser Altimeter (SLA)-01 and 02missions constitute a valuable pathfinder data set to test algorithms in preparation for the upcoming VCL(Vegetation Canopy Lidar) and ICESat (Ice, Cloud and Elevation Satellite) missions. Results from apreliminary SLA-01 data analysis are presented along with a brief description of the methodology and itsapplication to future spaceborne missions.

Tiny, passivelyQ-switched microlasers generate ultra-short pulses with output energies on the order of 100 kJ at few kHz rates to achieve mm-levelranging precision to satellite altitudesof 20,000 km. Special ranging receivers, combined with Poisson statistical analysis of the received photon distribution, enable the system to rapidly and reliably identify and extract the single photon laser echoes from the solar background. The enhanced rate of return, combined with a uniform signal strength, can actually drive down both systematic and random range errors. The new SLR2000 technology has already spawned exciting new applications. Compact microlaser altimeters, capable of mapping the surface of a planet or other celestial body at multikilohertz rates, is one such application, and a high altitude, airborne version is currently being developed under NASA's Instrument Incubator Program. Interplanetary microlaser transponders would be capable of performing decimeter ranging or subnanosecond time transfer to spacecraft throughout the inner Solar System, resulting in improved knowledge of planetary motions and librations and enhanced General Relativity experiments.

AN - 71291099; 11863032 AB - Space radiation dosimetry presents one of the greatest challenges in the discipline of radiation protection. This is a result of both the highly complex nature of the radiation fields encountered in low-Earth orbit (LEO) and interplanetary space and of the constraints imposed by spaceflight on instrument design. This paper reviews the sources and composition of the space radiation environment in LEO as well as beyond the Earth's magnetosphere. A review of much of the dosimetric data that have been gathered over the last four decades of human space flight is presented. The different factors affecting the radiation exposures of astronauts and cosmonauts aboard the International Space Station (ISS) are emphasized. Measurements made aboard the Mir Orbital Station have highlighted the importance of both secondary particle production within the structure of spacecraft and the effect of shielding on both crew dose and dose equivalent. Roughly half the dose on ISS is expected to come from trapped protons and half from galactic cosmic rays (GCRs). The dearth of neutron measurements aboard LEO spacecraft and the difficulty inherent in making such measurements have led to large uncertainties in estimates of the neutron contribution to total dose equivalent. Except for a limited number of measurements made aboard the Apollo lunar missions, no crew dosimetry has been conducted beyond the Earth's magnetosphere. At the present time we are forced to rely on model-based estimates of crew dose and dose equivalent when planning for interplanetary missions, such as a mission to Mars.

AN - 71261684; 11863030 AB - A review of solid state microdosimetry is presented with an emphasis on silicon-based devices. The historical foundations and basics of microdosimetry are briefly provided. Various methods of experimental regional microdosimetry are discussed to facilitate a comparison with the more recent development of silicon microdosimetry. In particular, the performance characteristics of a proportional gas counter and a silicon microdosimeter are compared. Recent improvements in silicon microdosimetry address the issues of requirement specification, non-spherical shape, tissue equivalence, sensitive volume definition (charge collection complexity) and low noise requirements which have previously impeded the implementation of silicon-based microdosimetry. A prototype based on silicon-on-insulator technology is described along with some example results from clinical high LET radiotherapy facilities. A brief summary of the applications of microdosimetry is included. c2001 Elsevier Science B.V. All rights reserved. JF - Nuclear instruments & methods in physics research.

AN - 71260303; 11863031 AB - Three-dimensional optical random access memories (3D ORAMs) are a new generation of high-density data storage devices. Binary information is stored and retrieved via a light induced reversible transformation of an ensemble of bistable photochromic molecules embedded in a polymer matrix. This paper describes the application of 3D ORAM materials to radiation dosimetry. It is shown both theoretically and experimentally, that ionizing radiation in the form of heavy charged particles is capable of changing the information originally stored on the ORAM material. The magnitude and spatial distribution of these changes are used as a measure of the absorbed dose, particle type and energy. The effects of exposure on 3D ORAM materials have been investigated for a variety of particle types and energies, including protons, alpha particles and 12C ions. The exposed materials are observed to fluoresce when exposed to laser light. The intensity and the depth of the fluorescence is dependent on the type and energy of the particle to which the materials were exposed. It is shown that these effects can be modeled using Monte Carlo calculations. The model provides a better understanding of the properties of these materials. which should prove useful for developing systems for charged particle and neutron dosimetry/detector applications. c2001 Published by Elsevier Science B.V.

Until the Tagish Lake fall, these asteroids had no analog in the meteorite collections. The Tagish Lake meteorite is a carbon-rich (4 to 5 weight %), aqueously altered carbonaceous chondrite and contains high concentrations of presolar grains and carbonate minerals, which is consistent with the expectation that the D-type asteroids were originally made of primitive materials and did not experience any extensive heating.

Analyses have now shown this carbonaceous chondrite to contain a suite of soluble organic compounds ( approximately 100 parts per million) that includes mono- and dicarboxylic acids, dicarboximides, pyridine carboxylic acids, a sulfonic acid, and both aliphatic and aromatic hydrocarbons. The insoluble carbon exhibits exclusive aromatic character, deuterium enrichment, and fullerenes containing "planetary" helium and argon. The findings provide insight into an outcome of early solar chemical evolution that differs from any seen so far in meteorites.

How do the soluble components behave during the ice segregation, especially mobile forms of contaminant heavy metals? The intent of this paper is to study redistribution of the mobile metals during formation of lens-type cryogenic structure freezing water-rich silt. The experimental data show that the concentration of pore solute increases during the segregation of ice including metal pollutants. The zones of high concentration are formed at the interface of segregation ice lens and mineral layers in freezing ground. The parameters of phase transition of water (start temperature of thawing and total heat of phase transition) in such zones are decreased with the increased concentration. Part of the liquid unfrozen water in the concentration zones of frozen silt consists of microscopic drops at the surface of ice crystals. Probably part of the dissolved mobile component is present in such liquid inclusions under subzero temperature. A fixation of metal pollutants takes place in the zones of concentration during ice segregation in freezing ground.

AN - 50157712; 2002-008352 AB - Thermoremanent magnetization (TRM) in hematite is larger than TRM in magnetite for grain sizes > or = 10 mu m. We show that hematite's weak spontaneous magnetization M (sub s) causes its strong TRM, since the self-demagnetizing field H (sub d) opposing large domain wall displacements is proportional to M (sub s) . In hematite, H (sub d) is comparable to the Earth's magnetic field but in magnetite, H (sub d) is 1000 times larger. As a result, Earth's field TRM of MD hematite ( nearly equal 0.3 Am (super 2) /kg) outweighs TRM and induced magnetization of MD magnetite ( nearly equal 0.01-0.02 Am (super 2) /kg and rivals TRM of single-domain and PSD magnetite as a source of magnetic anomalies on Earth and perhaps on Mars.

Uncertainties in sea surface temperatures and mountain wave drag over the ice sheets are investigated in sensitivity experiments. In many respects the climate and dynamical forcing of the stratosphere was opposite in these time periods, with reduced CO (sub 2) , increased topography, and increased latitudinal temperature gradients during the ice age, and increased CO (sub 2) , reduced topography and latitudinal temperature gradients during the Paleocene, representative of much of the Tertiary. The results show that the stratospheric response was often of an opposite nature as well, with the ice ages featuring a warmer stratosphere, increased residual circulation in the lower stratosphere (and decreased above), and weakened polar vortices, while the Paleocene simulation had a colder stratosphere, decreased residual circulation in the lower stratosphere (and increased above), with strengthened polar vortices. Analysis shows that the stratospheric response is very individualistic to the particular climate regime, and the opposite effects are not necessarily produced by inversely related mechanisms. Of particular importance in both climates is the reduced latitudinal gradient at high latitudes, which weakens high-latitude zonal winds and limits wave energy vertical propagation. Increased planetary wave forcing in the lower stratosphere accelerates the circulation during the ice ages. A strong increase in zonal winds during the Paleocene is the result of both decreased planetary wave forcing, associated with the reduced topography, and decreased mountain wave drag. The sensitivity experiments show that if tropical sea surface temperatures were warmer, the stratospheric residual circulation was enhanced, while stratospheric warmings are sensitive to the precise sea surface temperature specifications and mountain wave drag.

In the calculations we consider a volatile phase composed of H (sub 2) O, CO (sub 2) , and SO (sub 2) and take into account that the magmatic water erupted at the vent may condense as the eruption column rises into the Martian atmosphere. As two end-member models, we explore the eruption of rhyolitic and basaltic melt compositions containing different amounts of volatiles as well as having different eruption temperatures. Under current Martian atmospheric conditions eruption plumes are found to rise as high as 100 km for a mass eruption rate of 5 X 10 (super 7) kg s (super -1) , which is consistent with model calculations by Wilson and Head [1994]. In contrast, under a dense atmosphere (10 (super 5) Pa on the Martian surface) which may have existed earlier in Martian history, the same eruption plume reaches only about 25 km height. All magmatic water released during the eruption is found to freeze as it rises in the eruption column, which means that fallout from the plume will contain water ice which can be subsequently deposited in near surface layers. This ice may then suddenly melt due to higher surface heat flow or shallow intrusions leading to rapid release of water on the flanks of volcanoes. Only if the atmosphere were hotter in the past could the water in the eruption plume condense and produce rain rather than ice. Furthermore, the calculations show that smaller micron-size particles would be distributed globally from eruption plumes under current Martian conditions but would not have been as widely dispersed from plumes erupted into an earlier dense atmosphere.

The most recently published correction algorithm for the EMR1 data [Stum et al., 1998] is applied. The suggested drift correction for TMR data [Keihm et al., 1998, 2000] is also evaluated. The corrected EMRl data (1991-1996) produce a global (to + or -66 degrees the T/P latitude range) long-term mean wet troposphere correction 6 and 13 mm lower than TMR and ECMWF, respectively. The EMR2 data (1995-1999) yield a mean wet troposphere correction 2 and 9 mm lower than TMR and ECMWF, respectively. After removing mean differences all three microwave radiometers reproduce similar long-term zonal wet troposphere corrections compared to the ECMWF model (10-14 mm rms) and to each other (5-9 mm rms) with some zonally periodic differences, most <10 mm. The ECMWF model shows variations compared to the radiometers of over 30 mm before 1995, about 20-30 mm from 1995 to 1997, and up to 20 mm from 1998 to 1999. The intersatellite differences include a latitudinally dependent annual signal, reaching 10 mm in amplitude. Before correcting for the TMR drift there exists a global relative TMR-EMR1 drift of -1.6 + or - 0.4 mm y (super -1) , from 1992 to 1996. After correcting for the TMR drift the TMR-EMR1 trend is reduced to -0.4 + or - 0.2 mm y (super -1) , supporting the TMR drift correction. The TMR-EMR2 trend changes sign (direction) after an anomaly that occurred in one of the EMR2 brightness temperatures during June 1996. Before the anomaly, with (without) the TMR correction the relative TMR-EMR2 trend is -3.0 + or - 1.9 (-4.0 + or - 2.1) mm y (super -1) , again supporting the TMR drift correction. After the anomaly, through 1997 the TMR-EMR trend is 3.7 + or - 1.2 mm y (super -1) , and from 1998 to 1999 it is 0.8 + or - 0.6 mm y (super -1) . Copyright 2001 by the American Geophysical Union.

Inhibition of the renin-angiotensin system (RAS) improves symptoms and prognosis in heart failure. The experimental basis for these benefits remains unclear. We examined the effects of inhibition of ACE or blockade of angiotensin II type 1 (AT1) receptor on the haemodynamics, cardiac G-proteins, and collagen synthesis of rats with coronary artery ligation (CAL), a model in which chronic heart failure (CHF) is induced. 2. Rats were orally treated with the ACE inhibitor trandolapril (3 mg kg(-1) day(-1)) or the AT1 receptor blocker L-158809 (1 mg kg(-1) day(-1)) from the 2nd to 8th week after CAL. CAL resulted in decreases in the left ventricular systolic pressure and its positive and negative dP/dt, an increase in the left ventricular end-diastolic pressure, and the rightward shift of the left ventricular pressure-volume curve. Long-term treatment with either drug improved these signs of CHF to a similar degree. 3. Cardiac Gsalpha and Gqalpha protein levels decreased, whereas the level of Gialpha protein increased in the animals with CHF. Long-term treatment with trandolapril or L-158809 attenuated the increase in the level of cardiac Gialpha protein of the animals with CHF without affecting Gsalpha and Gqalpha protein levels. Cardiac collagen content of the failing heart increased, whose increase was blocked by treatment with either drug. 4. Exogenous angiotensin I stimulated collagen synthesis in cultured cardiac fibroblasts, whose stimulation was attenuated by either drug. 5. These results suggest that blockade of the RAS, at either the receptor level or the synthetic enzyme level, may attenuate the cardiac fibrosis that occurs after CAL and thus affect the remodelling of the failing heart.

The time series covers March 1997 to February 1998. Profile retrievals with maximum sensitivity in the upper troposphere show distinct seasonal cycles for all three molecules with maxima during October-December 1997. Best fits to the time series of daily averages yield peak 0.03-14 km columns (molecules cm super(-2)) of 1.54 x 10 super(18) for CO, 8.56 x 10 super(15) for C sub(2)H sub(6), and 6.56 x 10 super(15) for HCN during austral spring. Mixing ratio profiles of all three molecules during this time show maxima in the upper troposphere. Isentropic back trajectories suggest the elevated CO, C sub(2)H sub(6), and HCN columns above Wollongong originated from southern Africa or South America with no significant contribution from the intense tropical Asian emissions during the strong El Nino event of 1997-1998.

The goal of the experiment was to evaluate the overall performance of an empirically-based retrieval algorithm at S-band and L-band under a different set of conditions and to characterize the site-specific accuracy inherent within the technique. With high temporal frequency observations at S-band and L-band, we were able to observe large scale moisture changes following irrigation and rainfall events, as well as diurnal behavior of surface moisture among three plots, one bare, one covered with short grass and another covered with alfalfa. The L-band emitting depth was determined to be on the order of 0-3 or 0-5 cm below 0.30 cm super(3)/cm super(3) with an indication that it is less at higher moisture values. The S-band emitting depth was not readily distinguishable from L-band. The uncertainty in remotely sensed soil moisture observations due to surface heterogeneity and temporal variability in variables and parameters was characterized by imposing random errors on the most sensitive variables and parameters and computing the confidence limits on the observations. Discrepancies between remotely sensed and gravimetric soil moisture estimates appear to be larger than those we should expect from errors in variable and parameter estimation. This would suggest that a vegetation correction procedure based on more dynamic modeling may be required to improve the accuracy of remotely sensed soil moisture.

The present study substantiates the potentiality and the method of the determination of some HHD parameters along with a footprint-averaged rainfall from spectral/polarization microwave radiometer measurements. HHD parameters selected for the retrieval provide an effective description of the HHD, and at the same time their variations are detectable and distinguishable from radiometer measurements. In addition, availability of the HHD parameters allows the interpretation of the procedure of screening rainless footprints as a detection of the rainfall signal on the background of the retrieval errors. The method is tested for available hydrometeor profile simulation and demonstrated with the example of tropical rainfall measuring mission microwave imager (TRMM TMI) measurements processing.

Lakes from the Dry Valleys region of Antarctica have been investigated as possible analogs for extinct lake environments on early Mars. Sediment cores were collected in the present study from perennially ice-covered Lake Hoare in the Taylor Valley. These sediments were taken from a core in an oxic region of the lake and another core in an anoxic zone. Differences between the two cores were observed in the sediment color, Fe(II)/Fe(III) ratio, the presence of pyrite, the abundance of Fe, S, and some trace elements, and the C, N, and S isotope fractionation patterns. The results of visible-infrared reflectance spectroscopy (0.3-25 mu m), Moessbauer spectroscopy (77 and 4 K), and X-ray diffraction are combined to determine the mineralogy and composition of these samples. The sediments are dominated by plagioclase, K-feldspar, quartz, and pyroxene. Algal mats grow on the bottom of the lake and organic material has been found throughout the cores. Calcite is abundant in some layers of the sediment core from the shallow, oxic region, and pyrite is abundant in the upper sediment layers of the core from the deep, anoxic region of Lake Hoare. Analysis of the spectroscopic features due to organics and carbonates with respect to the abundance of organic C and carbonate contents was performed in order to select optimal spectral bands for remote identification of these components in planetary regoliths. Carbonate bands near 4 and 6.8 mu m ( similar to 2500 and 1500 cm super(-1)) were detected for carbonate abundances as low as 0.1 wt% CO sub(2). Organic features at 3.38, 3.42, and 3.51 mu m (2960, 2925, and 2850 cm super(-1)) were detected for organic C abundances as low as 0.06 wt% C. The delta super(13)C and delta super(15)N trends show a more complex organic history for the anoxic region sediments than for the oxic region sediments. The biogenic pyrite found in the core from the anoxic zone is associated with depleted delta super(34)S values and high organic C levels and could be used as a potential biomarker mineral for paleolakes on Mars.

ER - TY - JOUR T1 - Flight testing the parachute system for the Space Station crew return vehicle AN - 17677304; 5345375 AB - NASA has developed and tested a large parafoil for use in landing the International Space Station crew return vehicle. A series of tests using low- velocity airdrop pallets and prototype lifting bodies flights has demonstrated that the parafoil recovery system is a viable option for safely landing a crewed vehicle. The aerodynamic characteristics of the parafoil system have been determined through a series of flight-test maneuvers and subsequently successfully modeled using an eight-degree-of-freedom simulation program. An introduction to the requirements for the crew return vehicle, a description of the parafoil system, an overview of the testing performed, including several significant findings, a description of the techniques used to assess the aerodynamic performance of the parafoil system, and a discussion of the simulation of the parafoil system are presented.

N1 - Last updated - 2011-12-13 ER - TY - JOUR T1 - Influence of Land Surface Fluxes on Precipitation: Inferences from Simulations Forced with Four ARM-CART SCM Datasets AN - 1665487473; 5385817 AB - Four different Atmospheric Radiation Measurement Program Cloud and Radiation Test Bed (ARM-CART) Single-Column Model (SCM) datasets were used to force an SCM in a number of simulations performed to study the influence of land surface fluxes on precipitation. The SCM employed Goddard Earth Observing System (GEOS-2) GCM physics, which includes a recent version of prognostic cloud scheme (Microphysics of Clouds with Relaxed Arakawa-Schubert), and a land model (Simplified Simple Biosphere Model) coupled to a highly resolved soil hydrological description in the vertical. The four ARM-CART datasets employed in these studies are referred as case 1, case 3, case 4, and case 8. The SCM simulation results broadly confirm the previous findings that an increase in the solar absorption and surface evaporation helps to increase the local rainfall, but they also reveal that the magnitude of the rainfall increase is strongly affected by the ability of the background circulation to promote moist convection. The simulated precipitation increase was as large as 50% of the evapotranspiration increase for case 1 that covered a relatively wet period. It was substantially reduced for cases 3 and 4 covering a normal rainfall period and became negligible for case 8, a dry case. A part of evaporation increase became horizontal divergence of water vapor; this would have the potential of increasing the precipitation downstream of the test region. For a particular background circulation, it was found that the evaporation-precipitation relationship, often defined as recycling ratio, is remarkably robust even for a large range of vegetation covers, soil types, and initial soil moistures. Notwithstanding the limitations of only one-way interaction (i.e., the large scale influencing the regional physics and not vice versa), the current SCM simulations show that recycling ratio is a function of the background circulation and not a regional and/or seasonal feature. Indeed, a vigorous biosphere can help to produce more rainfall under wet conditions but may do little to dislodge a large-scale drought. It is pointed out that even though these inferences are robust, they are prone to weaknesses of the SCM physics as well as the assumption of the large scale remaining unaffected by changes of moist processes.

AN - 71145605; 11534722 AB - This paper describes a new strategy for the creation of chemically modified carbonaceous stationary phases. The strategy exploits the electroreduction of arenediazonium salts as a means for functionalizing the surface of glassy carbon (GC) and porous graphitic carbon (PGC) stationary phases. The one-electron reduction of these salts forms an arene radical which then couples via a carbon-carbon linkage to the carbon framework at the surface of the stationary phase. Two arenediazonium-based modifiers were used in evaluating the potential utility of this strategy: 4-nitrobenzenediazonium tetrafluoroborate for the GC and PGC phases and 4-hexylbenzenediazonium tetrafluoroborate for only the PGC phases. Modifications were carried out by packing the phases into a column used for electrochemically modulated liquid chromatography. The effectiveness of the modifications was assessed by X-ray photoelectron spectroscopy and by comparing the liquid separation of a series of mixtures before and after coating deposition. For the nitrobenzyl-modified GC phase, the test mixture contained both anisole and fluoranthene. The performance of the nitrobenzyl- and hexylbenzyl-modified PGC stationary phases was characterized by the separations of substituted phenols (i.e., nitrophenol and resorcinol) and a few important pharmaceutical agents (i.e., hexobarbital, oxazepam, and nitrazepam). The potential utility of this modification procedure to form stationary phases that are stable upon extended exposure to aggressive mobile phases is discussed and briefly examined.

AN - 72232418; 11681349 AB - Polylactic acid (PLA), a kind of aliphatic polyester, is a biodegradable polymer with outstanding biocompatibility. The degradation of PLA is a complex process involving four main phenomena, namely water absorption, ester cleavage, diffusion of soluble oligomers, and solubilization of fragments. This paper emphasizes on the following aspects: 1) present understanding of the hydrolytic degradation and enzymatic degradation of PLA and autocatalystic degradation mechanism in the bulk PLA; 2) main factors influencing PLA degradation; 3) biological results; 4) the development in application of PLA.

AN - 72231922; 11681344 AB - To observe and investigate the variation and heredity of the offspring of dry seeds of rice carried by satellite, hence to select early maturing mutants, and to cultivate directly "Ganzaoxian 47" new varieties for production application. Isozymes analyses and studies of the new varieties and its original CK varieties were made. Dry seeds of rice restorer line were carried to the space on board a recoverable satellite for 7 d in 1992. After recovery the seeds were planted in the field to study the agricultural characters, yield, disease resistance, rice quality and peroxidase isozymes change. Its agricultural characters, yield, disease resistance, rice quality and peroxidase isozymes all showed distinct changes, and new varieties were cultivate directively for production application. It could be considered that certain variations of the rice seeds induced by the space conditions were heritable to the offspring's, and directive cultivation of new varieties is possible for production application. It could be used as a new method for mutagenic seed breeding.

AN - 72222834; 11669121 AB - Following an enthusiastic start in 1985, ESA's life support technology development programme was re-assessed in the mid- to late-1990s to reflect the strong reduction in European manned space ambitions which occurred at that time. Further development was essentially restricted to activities that could constitute ISS upgrades or enhancements, or support ISS utilisation/operations, together with a single, limited, activity (MELISSA) aimed at bioregenerative life support, in the continuing hope that there might be "life after Station". The paper describes the current status of these activities and summarises the main priorities for future development that were identified at the April 1999 Workshop on Advanced Life Support. c 2001.

AN - 72220187; 11669132 AB - Most launch vehicles and satellites in the US inventory rely upon the use of hypergolic rocket propellants, many of which are toxic to humans. These fuels and oxidizers, such as hydrazine and nitrogen tetroxide have threshold limit values as low as 0.01 PPM. It is essential to provide space workers handling these agents whole body protection as they are universally hazardous not only to the respiratory system, but the skin as well. This paper describes a new method for powering a whole body protective garment to assure the safety of ground servicing crews. A new technology has been developed through the small business innovative research program at the Kennedy Space Center. Currently, liquid air is used in the environmental control unit (ECU) that powers the propellant handlers suit (PHE). However, liquid air exhibits problems with attitude dependence, oxygen enrichment, and difficulty with reliable quantity measurement. The new technology employs the storage of the supply air as a supercritical gas. This method of air storage overcomes all of three problems above while maintaining high density storage at relatively low vessel pressures (<7000 kPa or approximately 1000 psi). A one hour prototype ECU was developed and tested to prove the feasibility of this concept. This was upgraded by the design of a larger supercritical dewar capable of holding 7 Kg of air, a supply which provides a 2 hour duration to the PHE. A third version is being developed to test the feasibility of replacing existing air cooling methodology with a liquid cooled garment for relief of heat stress in this warm Florida environment. Testing of the first one hour prototype yielded data comparable to the liquid air powered predecessor, but enjoyed advantages of attitude independence and oxygen level stability. Thermal data revealed heat stress relief at least as good as liquid air supplied units. The application of supercritical air technology to this whole body protective ensemble marked an advancement in the state-of-the-art in personal protective equipment. Not only was long duration environmental control provided, but it was done without a high pressure vessel. The unit met human performance needs for attitude independence, oxygen stability and relief of heat stress. This supercritical air (and oxygen) technology is suggested for microgravity applications in life support such as the Extravehicular Mobility Unit. c 2001. Elsevier Science Ltd. All rights reserved.

AN - 72220083; 11669126 AB - Weight loss is a frequent problem in space flights. We now claim that it may affect performance and drug-seeking behavior by altering midbrain neurochemistry. In food-deprived rats (20-30% underweight) basal extracellular dopamine levels in the nucleus accumbens decrease to 40-50% of normal and locomotion is depressed. However, amphetamine-induced dopamine release and locomotion are higher than in controls (1825% vs. 595% after a 25 micromoles d-amphetamine intraaccumbens infusion). The lower basal and the higher stimulated dopamine levels suggest that the neurotransmitter accumulates presynaptically in the accumbens of the underweight rats due to subnormal basal release. Psychostimulants are more rewarding for underweight subjects possibly because they release significantly more dopamine from elevated presynaptic stores into the accumbens. Consequently, weight loss can lead both to depression of performance and propensity to substance abuse. These effects should be considered when providing nutritional resources for space flights so that weight loss is limited. c 2001. Elsevier Science Ltd. All rights reserved.

AN - 72217524; 11669120 AB - The solar or laser optical radiation impact to humans in space depends on the intensity, on the exposure type (direct or indirect) & duration and on the matching of radiation wavelength to tissue characteristics. The main protection factor in space is the application of exposure limits. This paper describes the main biological optical interaction parameters, the optical exposure hazards and the development of a small active lightweight indicator, with output beeper rate depended to the ratio of optical irradiance/exposure limit. The indicator may be used as warning element on the side of helmets, goggles, spectacles, etc, with low power consumption. Electronically the indicator is an intensity/frequency converter, based on the value of the ratio of exposure/exposure limits, with audio & light beepers like the indication output of the ionizing (radioactive) radiation monitors. c 2001.

AN - 72215791; 11669117 AB - Activities associated with human missions to the Moon or to Mars will interact with the environment in two reciprocal ways: (i) the mission needs to be protected from the natural environmental elements that can be harmful to human health, the equipment or to their operations: (ii) the specific natural environment of the Moon or Mars should be protected so that it retains its value for scientific and other purposes. The following environmental elements need to be considered in order to protect humans and the equipment on the planetary surface: (i) cosmic ionizing radiation, (ii) solar particle events; (iii) solar ultraviolet radiation; (iv) reduced gravity; (v) thin atmosphere; (vi) extremes in temperatures and their fluctuations; (vii) surface dust; (viii) impacts by meteorites and micrometeorites. In order to protect the planetary environment. the requirements for planetary protection as adopted by COSPAR for lander missions need to be revised in view of human presence on the planet. Landers carrying equipment for exobiological investigations require special consideration to reduce contamination by terrestrial microorganisms and organic matter to the Greatest feasible extent. Records of human activities on the planet's surface should be maintained in sufficient detail that future scientific experimenters can determine whether environmental modifications have resulted from explorations.

AN - 72212795; 11669119 AB - NASA is very interested in improving its ability to monitor and forecast the radiation levels that pose a health risk to space-walking astronauts as they construct the International Space Station and astronauts that will participate in long-term and deep-space missions. Human exploratory missions to the moon and Mars within the next quarter century, will expose crews to transient radiation from solar particle events which include high-energy galactic cosmic rays and high-energy protons. Because the radiation levels in space are high and solar activity is presently unpredictable, adequate shielding is needed to minimize the deleterious health effects of exposure to radiation. Today, numerous models have been developed and used to predict radiation exposure. Such a model is the Space Environment Information Systems (SPENVIS) modeling program, developed by the Belgian Institute for Space Aeronautics. SPENVIS, which has been assessed to be an excellent tool in characterizing the radiation environment for microelectronics and investigating orbital debris, is being evaluated for its usefulness with determining the dose and dose-equivalent for human exposure. Thus far. the calculations for dose-depth relations under varying shielding conditions have been in agreement with calculations done using HZETRN and PDOSE, which are well-known and widely used models for characterizing the environments for human exploratory missions. There is disagreement when assessing the impact of secondary radiation particles since SPENVIS does a crude estimation of the secondary radiation particles when calculating LET versus Flux. SPENVIS was used to model dose-depth relations for the blood-forming organs. Radiation sickness and cancer are life-threatening consequences resulting from radiation exposure. In space. exposure to radiation generally includes all of the critical organs. Biological and toxicological impacts have been included for discussion along with alternative risk mitigation methods--shielding and anti-carcinogens. c 2001. Elsevier Science Ltd.

N1 - Last updated - 2014-03-21 ER - TY - JOUR T1 - Mineralogy of a natural As-rich hydrous ferric oxide coprecipitate formed by mixing of hydrothermal fluid and seawater; implications regarding surface complexation and color banding in ferrihydrite deposits AN - 52208296; 2001-057092 AB - We characterized the most As-rich natural hydrous ferric oxide (HFO) material ever reported using powder X-ray diffraction (pXRD), transmission electron microscopy (TEM), X-ray fluorescence spectroscopy (XRF), light element analysis using gas chromatography (GC), visible-infrared (vis-IR) diffuse reflectivity, (super 57) Fe Mossbauer spectroscopy, and superconducting quantum interference device (SQUID) magnetometry. We find that the natural As-HFO material is very similar to synthetic coprecipitated As-HFO materials, but is significantly different from all known natural and synthetic As-free HFO materials and ferrihydrite samples. The pXRD patterns show systematic differences with patterns for 2-line ferrihydrite, that are interpreted as evidence for significant populations of oxygen-coordinated Fe-As pairs. Observations by TEM, combined with energy dispersive spectroscopy (EDS) microanalysis, show agglomerations of nanophase primary particles and no evidence for other Fe- or As-bearing phases. Mossbauer spectroscopy shows octahedrally coordinated Fe (super 3+) , with a large fraction ( approximately 20%) of the octahedral Fe environments that are significantly distorted by the presence of As, compared to the Fe local environments in As-free ferrihydrite and HFO samples. The loss on ignition (LOI) is quantitatively consistent with OH+H (sub 2) O, measured by GC, which, in turn, is consistent with approximately 1 nm diameter primary particles having all their surface cations (Fe (super 3+) , As (super 5+) , Si (super 4+) , C (super 4+) ) coordinated on the free surface side by OH (super -) and OH (sub 2) . The banding into adjacent yellowish and reddish layers that occurs in the As-HFO deposits was studied by performing mineralogical analyses of the separated adjacent layers of two couplets of yellowish and reddish material. The yellowish samples were found not to contain secondary crystalline phases (as did the reddish samples, in small amounts) and to be relatively As-rich, C- and Si-poor. The observed anticorrelations between As and Si and between As and inorganic C suggest that natural HFOs, which usually contain significant molar amounts of Si, may not be as efficient at surface complexing As (and P) as their Si and C-free synthetic counterparts, unless formed by co-precipitation with the As (or P). The yellowish and reddish layers were also clearly resolved by both Mossbauer spectroscopy and magnetometry. Complexation of arsenate onto the HFO core was found to significantly increase the average quadrupole splitting (QS) obtained from Mossbauer spectroscopy by an amount that could not be explained by other chemical differences and that is consistent with an approximately 1 nm diameter particle size and somewhat smaller HFO core. The Munsell hue YR index (5-10 YR) was found to be strongly correlated to the average QS, thereby establishing that the color differences, corresponding to the measured shifts of the main visible band edge, are due to the local distortions in the (super [6]) Fe (super 3+) environments that are induced by As complexation, via their influence on the relevant ligand field transitions. SQUID magnetometry allows the following observations. (1) The superparamagnetic to superferromagnetic transitions occur at 25 K and lower in As-HFO, compared to 55 K in synthetic 2-line ferrihydrite, suggesting a smaller magnetic primary particle (or core) size for As-HFO and inter-particle magnetic interaction reduction by surface complexed As, Si, and C. (2) The ratio of supermoment magnitude to magnetic particle size (m (super 2) /n, where m is the net number of Fe (super 3+) atomic moments per supermoment and n is the number of Fe (super 3+) cations per particle or HFO core) decreases with increasing As content in the sequence synthetic-HFO>reddish-As-HFO>yellowish-As-HFO. (3) The magnetic susceptibility magnitudes for As-HFO and synthetic 2-line ferrihydrite differ by a factor of 10 and suggest different supermoment formation mechanisms (m (super 2) /n1, respectively) related to differences in intra-particle cationic and anionic disorder and magnetic particle size.

In the case of organic compounds in meteorites and interplanetary dust particles (IDPs), the most useful isotopic tracer has been deuterium (D). We discuss four processes that are expected to lead to D enrichment in interstellar materials and describe how their unique characteristics can be used to assess their relative importance for the organics in meteorites. These enrichment processes are low-temperature gas phase ion-molecule reactions, low-temperature gas-grain reactions, gas phase unimolecular photodissociation, and ultraviolet photolysis in D-enriched ice mantles. Each of these processes is expected to be associated with distinct regiochemical signatures (D placement on the product molecules, correlation with specific chemical functionalities, etc.), especially in the molecular population of polycyclic aromatic hydrocarbons (PAHs). We describe these differences and discuss how they may be used to delineate the various interstellar processes that may have contributed to meteoritic D enrichments. We also briefly discuss how these processes may affect the isotopic distributions in C, O, and N in the same compounds.

The method uses the precise measurement of several metals whose proportions contrast strongly between dust and salt and vary substantially between dust types. The method is applied to a small suite of ice samples from the Taylor Dome core in coastal West Antarctica. In glacial times wind strength in the West Antarctic region was apparently high, and extensive sea-ice cover prevented incorporation of salt into the atmospheric load. At the termination of the glacial period, increased salt in the dust-salt mixture indicates that sea ice diminished, but wind strength continued high, and unchanged dust composition indicates unchanged source areas. At about 10,000-11,000 y.B.P., sea-ice cover have briefly returned to glacial conditions, but wind conditions remained in the milder postglacial condition. Next, sea ice retreated, and an abrupt change in dust composition indicates changed source materials or terranes. Extension of this analysis to more sites, should provide firm constraints on past wind strengths, extent of sea-ice cover, deposition fluxes of salt and dust, and changing continental source areas of dust.

These aerosols are complex mixtures of soil dust and anthropogenic particles from a variety of sources, including fossil fuel combustion, biomass burning, mining, smelting, and other industrial processes, plus reaction products of heterogeneous processes that affect these particles during transport. In the coastal marine atmosphere, these particles could be further mixed with marine aerosols. To provide examples of the diversity of chemical and physical properties of east Asian aerosols in the spring, individual aerosol particle samples were collected in April and May 1999 in three different environments in China: Qingdao on the coast of the East China Sea, Beijing in the northeast interior, and Mount Waliguan in remote northwestern China. Results reveal that aerosols in this region are complex and heterogeneous. In addition to significant differences in aerosol composition and size distributions among the samples, each sample contains a large number of polyphase aggregates. Many of the particles also have irregular shapes; for a number of the particle types, the irregular shapes should persist even at high ambient RH. Because composition, degree and nature of polyphase aggregation, and shape all effect aerosol radiative properties, the complex state of east Asian aerosols presents a challenge for the modeling of aerosol radiative forcing in the region.

Each camera is characterized by small physical size and mass ( approximately 6 X 6 X 12 cm, including baffle; <500 g), low power requirements (<2.5 W, including power supply losses), and high science performance (1000 X 1000 pixel, low noise). The Wide Angle (WA) camera will have the capability to map Mars in five visible and two ultraviolet spectral bands at a resolution of better than 8 km/pixel under the worst case downlink data rate. Under better downlink conditions the WA will provide kilometer-scale global maps of atmospheric phenomena such as clouds, hazes, dust storms, and the polar hood. Limb observations will provide additional detail on atmospheric structure at 1/3 scale-height resolution. The Medium Angle (MA) camera is designed to study selected areas of Mars at regional scale. From 400 km altitude its 6 degrees FOV, which covers approximately 40 km at 40 m/pixel, will permit all locations on the planet except the poles to be accessible for image acquisitions every two mapping cycles (roughly 52 sols). Eight spectral channels between 425 and 1000 nm provide the ability to discriminate both atmospheric and surface features on the basis of composition. The primary science objectives of MARCI are to (1) observe Martian atmospheric processes at synoptic scales and mesoscales, (2) study details of the interaction of the atmosphere with the surface at a variety of scales in both space and time, and (3) examine surface features characteristic of the evolution of the Martian climate over time. MARCI will directly address two of the three high-level goals of the Mars Surveyor Program: Climate and Resources. Life, the third goal, will be addressed indirectly through the environmental factors associated with the other two goals. Copyright 2001 by the American Geophysical Union.

TEGA has the capability of performing differential scanning calorimetry on eight small (0.038 mL) soil samples selected in the vicinity of the lander. The samples will be heated in ovens to temperatures up to 950 degrees C, and the volatile compounds water and carbon dioxide, which are released during the heating, will be analyzed in the EGA. The power required by the sample oven is continuously monitored during the heating and compared to that required to heat simultaneously a similar, but empty, oven. The power difference is the output of the DSC. Both endothermic and exothermic phase transitions can be detected, and the data can be used in the identification of the phases present. By correlating the gas release with the calorimetry, the abundance of the volatile compounds associated with the different phases can be determined. The EGA may also be able to detect the release of oxygen associated with any Superoxide that may be on the surface of the soil grains. The instrument can detect the melting of ice in the DSC down to abundances on the order of 0.2% of the sample, and it can detect the decomposition of calcite, CaCO (sub 3) , down to abundances of 0.5%. Using the EGA, TEGA can detect small amounts of water, down to 8 ppm in the sample, and it can detect the associated release of CO (sub 2) down to the equivalent abundances of 0.03%. The EGA also has the ability to determine the (super 13) C/ (super 12) C ratio in the evolved CO (sub 2) , but it is not clear if the accuracy of this ratio will be sufficient to address the scientific issues.

Using the National Oceanic and Atmospheric Administration (NOAA) advanced very high resolution radiometer (AVHRR) channel 1, we also measured the aerosol optical depth (AOD (sub S ) ) and albedo over a region of the North Atlantic Ocean extending from 15 degrees -35 degrees N to 12 degrees -25 degrees W. We observe large changes in AT (sub T ) and AOD (sub T ) when dust outbreaks pass over this region. Using all these data, we derive the asymmetry factor (g), the single-scattering albedo (omega ), and the local mean AOD (sub T ) and we compute the direct radiative forcing Delta F attributable to mineral dust. The local radiative forcing obtained is over the ocean Delta F = -9.7 W/m2 and for the land Delta F = -4.5 W/m (super 2) with an error of + or -25%. Extending these results to global-scale averages, we obtain values of Delta F of-1.22 W/m (super 2) over the ocean and -0.57 W/m (super 2) over land. The forcings attributable to dust are comparable in magnitude to those reported in the literature for anthropogenic sulphate and for biomass burning aerosols.

This event was observed by several in situ and remote sensing atmospheric measurement stations. Dramatic reductions in boundary layer visibility were recorded and the resultant peak backscatter coefficients exceeded prevailing upper tropospheric background conditions by at least 2 orders of magnitude. An analysis of this event is given using lidar vertical backscatter profilometry, concurrent Sun photometer opacity data, and transport modeling. At San Nicolas Island the measured and modeled aerosol optical thickness at 500 nm increased dramatically from 0.15 on April 25 to 0.52 on April 26-27. Volume size distribution on April 27 exhibited a prominent coarse mode at 1-2 mu m radius, and single-scattering albedo was observed to increase from 0.90 in the blue to 0.93 in the near infrared. Concurrent lidar observations tracked the evolution of the plume vertical structure, which consisted of up to three well-defined layers distributed throughout the free troposphere.

Four experiments with the NASA GISS atmospheric general circulation model, which includes a soil dust aerosol model, are compared, all using a prescribed climatological sea surface temperature as a lower boundary condition. In one experiment, dust is included as a dynamic tracer with no radiative effect, whereas dust interacts with radiation in the other simulations. The single-scattering albedo of dust particles is prescribed to be globally uniform in the experiments with radiatively active dust, although this albedo is varied from experiment to experiment. On a global scale the radiative forcing by dust generally causes a reduction in the atmospheric dust load, corresponding to a decreased dust source flux. The dust source flux and its changes are analyzed in more detail for the main source regions. This analysis shows that the reduction varies both with the season and with the single-scattering albedo of the dust particles. The experiments show that dust radiative forcing can lead to significant changes both in the soil dust cycle and in the climate state. To estimate dust concentration and radiative forcing by dust more accurately, dust size distributions and dust single-scattering albedo in the model should be a function of the source region, because dust concentration and the climate response to dust radiative forcing are sensitive to dust radiative parameters.

A kinetic approach under thermodynamic constraint is utilized to model the condensation/evaporation processes, and other important aerosol processes and influential components (e.g., dust/sea-salt generation, NH (sub 3) emissions, gravitational settling, nucleation) are taken into account in this analysis. The model is used to study the Pacific Exploratory Mission-West B period (March 1-6, 1994). It is found that (1) during strong continental outflow, in general, the fine aerosol mode ( 2 mu m in aerodynamic diameter) attracts nitrate. However, in the dust plume, sulfate preferentially resides in the coarse mode due to larger coarse mode mass loading; (2) particulate nitrate coupled with particulate ammonium in the fine mode is predicted over regions where high gaseous NH (sub 3) mixing ratios are present (lower courses of the Huang river); (3) dust and sea-salt particles provide important reaction surfaces for sulfate production in the troposphere and increase sulfate production rates by 20 - 80%; and (4) soil dust and sea salt provide an important source of boundary layer and free troposhpere alkaline material, and these cations play an important role in controlling the partitioning of semivolatile HNO (sub 3) throughout large portions of the troposphere, increasing particulate nitrate levels 10 - 50%.

Further, the human contribution to the mineral aerosol concentration is difficult to quantify. We have performed several global sensitivity experiments to investigate the radiative forcing due to mineral dust. Two global data sets of mineral aerosol distribution are used. Radiative transfer schemes for thermal infrared and solar radiation are used in the calculations. We have investigated the sensitivity of the global radiative forcing to the spatial distribution of the aerosols, including the altitude, the size distribution, and optical parameters. Our strongest emphasis has been on the size distribution of the mineral aerosol, for which we have found a strong sensitivity. A range of -0.7 Wm (super -2) to 0.5 Wm (super -2) is estimated for the human influence on the global radiative forcing due to mineral aerosols. We find it almost as probable with a positive radiative forcing as with a negative forcing. Even if the global mean radiative forcing is small, there are large contributions of different sign in certain regions. Copyright 2001 by the American Geophysical Union.

The site was a vegetation-free saline playa where the surface formed "ephemeral crusts," crusts that form after rainfall. Sometimes these crusts were destroyed and often a layer of particles on the crust would engage in vigorous aeolian activity. Three "phases" of active sand drifting are defined as almost no movement (extreme supply limitation), loose particles on crust with some degree of sand drift (moderate supply limitation), and unlimited source movement corresponding to a destroyed surface crust (unlimited supply). These "phases" occurred 45, 49, and 6% of the time, respectively. The accumulation of loose particles on the crust was mostly the result of in situ formation. Crusted sediments with loose particles on top can exhibit mass flux rates about the same as for noncrusted sediments. Crusted sediments limit or eliminate sand drift in two conditions: for rough crusts that effect a sufficiently high threshold friction velocity (above the wind friction velocity) and for limited amounts of loose particles on the crust where particle supply is less than would be transported in normal saltation for a thick sandy surface. These "supply-limited" cases are similar to wind erosion of limited spilled material on a hard concrete surface. We quantified "supply limitation" by defining a "potential" or "supply unlimited" sand drift function Q = AG where A represents supply limitation that decreases as the particle source is depleted. Here Q is the mass of sand transported through a surface perpendicular to the ground and to the wind and having unit width during time period t, and G = Sigma u (sub *) (u (super 2) (sub *) - u (super 2) (sub *t ) ) dt for u (sub *) > u (sub *t) . G is integrated for the same time period t as for Q, u (sub *) is the friction velocity of the wind, and u (sub *t ) is the threshold friction velocity of the wind. Hard crusts (usually formed in the summer) tended to show almost no change of threshold friction velocity with time and often gave total protection from wind erosion. Rough crusts provided sufficient protection expressed as high threshold friction velocities. For these high threshold friction velocities, aeolian activity was greatly reduced or practically prevented. The softest crusts, usually formed in the winter, provided much less protection and sometimes were destroyed by the wind. Following this destruction the "potential" or "supply unlimited" sand drift would be observed. Copyright 2001 by the American Geophysical Union.

At least two types of heterogeneous reactions occur on the surface of these particles. Upon initial exposure of the oxide to NO (sub 2) there is a loss of NO (sub 2) from the gas phase by adsorption on the particle surface, i.e., NO (sub 2) (g) --> NO (sub 2) (a). As the reaction proceeds, a reduction of gaseous NO (sub 2) to NO, NO (sub 2) (g) --> NO (g) is found to occur. Initial uptake coefficients gamma (sub 0) for NO (sub 2) on the surface of these particles have been measured at 298 K using a Knudsen cell reactor coupled to a mass spectrometer. For the oxides studied, alpha ,gamma -Al (sub 2) O (sub 3) , alpha gamma -Fe (sub 2) O (sub 3) , TiO (sub 2) , SiO (sub 2) , CaO, and MgO, gamma (sub 0) ranges from < 4 X 10 (super -10) for SiO (sub 2) to 2 X 10 (super -5) for CaO with most values in the 10 (super -6) range. For authentic samples of China loess and Saharan sand, similar reactivity to the oxides is observed with gamma (sub 0) values of 2 X 10 (super -6) and 1 X 10 (super -6) , respectively. For HNO (sub 3) the reactivity is 1-2 orders of magnitude higher. Using these laboratory measurements, the impact of heterogeneous reactions of NO (sub 2) and HNO (sub 3) on mineral dust in tropospheric ozone formation and on O (sub 3) -precursor relationships is assessed using a time-dependent, multiphase chemistry box model. Simulations with and without heterogeneous reactions were conducted to evaluate the possible influence of these heterogeneous reactions on ambient levels. Results show that values of the initial uptake for NO (sub 2) and HNO (sub 3) , adjusted for roughness effects, must be greater than 10 (super -4) to have an appreciable impact on NO (sub x ) , HNO (sub 3) and O (sub 3) concentrations for the conditions modeled here. Thus the measured uptake coefficients for NO (sub 2) on dry surfaces are just below the lower limit to have an impact on the photochemical oxidant cycle, while the heterogeneous reactivity of HNO (sub 3) is sufficiently large to have an effect. Under conditions of high mineral dust mass loadings and/or smaller size distributions the importance of these reactions (both NO (sub 2) and HNO (sub 3) ) is expected to increase.

The parameterization uses six particle size divisions in the range 0.3-30 mu m radius, and all calculations are performed on each division independently, using the GCM's prognostic variables. The dust production scheme works within the GCM and includes dependencies on particle size distribution, soil moisture, vegetation, and friction velocity. Dust transport is carried out by the GCM's tracer advection scheme and includes vertical motion due to convection, gravitational settling, and turbulent mixing in the boundary layer. Wet and dry deposition processes are included within the GCM's precipitation schemes. Representative dust radiative parameters are incorporated into the GCM's two stream radiation code. Modeled monthly average near-surface dust concentrations are compared with observations: good agreement is seen in most locations, though the dust scheme tends to produce too little dust from China and too much from Australia in the southern spring. Global annual mean direct forcing due to the inclusion of dust in the GCM is +0.07 W m (super -2) at the top of the atmosphere (TOA) and -0.82 W m (super -2) at the surface. The geographical distributions of annual mean forcings are very inhomogeneous, with peak values exceeding the global means by a factor of approximately 2 orders of magnitude.

It is based on the SKIRON/Eta modeling system and the Eta/NCEP regional atmospheric model. The dust modules of the entire system incorporate the state of the art parameterizations of all the major phases of the atmospheric dust life such as production, diffusion, advection, and removal. These modules also include effects of the particle size distribution on aerosol dispersion. The dust production mechanism is based on the viscous/turbulent mixing, shear-free convection diffusion, and soil moisture. In addition to these sophisticated mechanisms, very high resolution databases, including elevation, soil properties, and vegetation cover are utilized. The entire system is easily configurable and transferable to any place on the Earth, it can cover domains on almost any size, and its horizontal resolution can vary from about 100 km up to approximately 4 km. It can run on one-way-nested form if necessary. The performance of the system has been tested for various dust storm episodes, in various places and resolution using gridded analysis or forecasting fields from various sources (ECMWF and NCEP) for initial and boundary conditions. The system is in operational use during the last two years, providing 72 hour forecasts for the Mediterranean region. The results are available on the internet (http://www.icod.org.mt and http://forecast.uoa.gr). Copyright 2001 by the American Geophysical Union.

During 1998, two multifilter rotating shadow-band radiometers (MFRSRs), operated by Washington State University (WSU) and by the USDA UV-B program, were used to collect data on the Columbia Plateau atmosphere. Analysis of these data by an automated Langley algorithm provided retrievals for total optical thickness, allowing for calculation of aerosol optical thickness (AOT) and the top-of-atmosphere (TOA) instrument signal. Statistical evaluation of the TOA signal permitted recalculation of optical thickness using the Bouguer-Lambert-Beer law and resulted in improved estimates of aerosol optical thickness (AOT). Results for AOT and the associated Aangstroem parameters are presented here for an April 1998 dust event for two colocated Columbia Plateau sites. AOT at 500 nm went from background levels (seasonally dominated by regional windblown dust) of approximately 0.2 to more than 0.4 during the event maximum on April 27, not returning to normal levels until April 30. Comparison of 500-nm AOT between the two MFRSR showed a root-mean-square (RMS) difference of 0.016. The Aangstr:ouml;m exponent alpha reached a minimum of approximately 0.2, and the beta coefficient reached a maximum of approximately 0.35, both on April 27, coincident with the AOT maximum. Contemporaneous aerosol sampling in Spokane, Washington, provided (1) elemental data that strongly support our interpretation of this event as an influx of Asian dust without significant sulfur enrichment and (2) event maximum PM (sub 10) measurements approximately 80 mu g/m (super 3) consistent with Pullman event maximum AOT results, assuming a 3-4 km thick dust layer.

A new on-line dust tracer model coupled with a regional-scale meteorological model is developed and applied to this dust storm episode. The results for two large dust events that started during April 14-15 and 19-20, 1998, have been analyzed and discussed. The first dust storm was trapped in a cutoff vortex developed over the China plain. A modeled 3-D structure of dust associated with this cutoff vortex agreed with an observed time-height cross section of dust concentration. Results show that the strong subsidence at the backside of the vortex restricted the dust layer below 3 km level. Model analysis revealed that the second dust event that started during April 19-20 over inland China was the origin of a dust episode reported over North America. The trans-Pacific dust transport simulation successfully showed the dust onset near the West Coast of North America. Elevation of the dust layer during the long-range transport was below 3 km. The model is extended to include the transport of an Asian origin anthropogenic tracer over the North Pacific Rim. Both the natural-origin mineral dust and the Asian-origin anthropogenic tracer are simultaneously transported even if their emission regions are different.

The average dust concentration at these groundbased sites was 82 mu g m (super -3) ; this is lower than the lowest average concentration observed over the nine major Chinese deserts (arithmetic mean value of 270 mu g m (super -3) ), and it also is lower than that over the Loess Plateau (170 mu g m (super -3) ). The elemental mass-particle size distributions for several major dust-derived elements (Al, Ca, Fe, K, Mn, Si, and Ti) were approximately lognormal, but those for Al, Fe, and Ti differed from Ca, K, and Si. Dry deposition velocities calculated from the observed size distributions and a two-layer deposition model averaged 2.7 cm (super -1) for Al, Fe, and Ti. For Ca, K, and Si, which appear to be more strongly affected by local Tibetan sources, the average calculated dry deposition velocity was 4.3 cm s (super -1) . Wet deposition fluxes estimated from scavenging ratios indicate that less than 10% of the total deposition on the Tibetan Plateau is attributable to wet removal during the 9 months for which data are available. The yearly mean dust deposition rate (local plus remote and dry plus wet) is estimated to be of the order of approximately 100 g m (super -2) yr (super -1) , which is lower than that onto the Chinese desert regions (320 g m (super -2) yr (super -1) ) or the Loess Plateau (250 g m (super -2) yr (super -1) ), suggesting that the sources upwind of China, and the Tibetan Plateau itself, are not major sources for Asian dust.

Both data sets, comprising more than a decade of global, daily images, are commonly used to evaluate aerosol transport models. The present comparison is based on monthly averages, constructed from daily images of each data set for the period between 1984 and 1990, a period that excludes contamination from volcanic eruptions. The comparison focuses on the Northern Hemisphere subtropical Atlantic Ocean, where soil dust aerosols make the largest contribution to the aerosol load, and are assumed to dominate the variability of each data set. While each retrieval is sensitive to a different aerosol radiative property (absorption for the TOMS AI versus reflectance for the AVHRR AOT), the seasonal cycles of dust loading implied by each retrieval are consistent, if seasonal variations in the height of the aerosol layer are taken into account when interpreting the TOMS AI. On interannual timescales, the correlation is low at most locations. It is suggested that the poor interannual correlation is at least partly a consequence of data availability. When the monthly averages are constructed using only days common to both data sets, the correlation is substantially increased: this consistency suggests that both TOMS and AVHRR accurately measure the aerosol load in any given scene. However, the two retrievals have only a few days in common per month, so these restricted monthly averages have a large uncertainty. Calculations suggest that at least 7 to 10 daily images are needed to estimate reliably the average dust load during any particular month, a threshold that is rarely satisfied by the AVHRR AOT due to the presence of clouds in the domain. By rebinning each data set onto a coarser grid, the availability of the AVHRR AOT is increased during any particular month, along with its interannual correlation with the TOMS AI. The latter easily exceeds the sampling threshold due to its greater ability to infer the aerosol load in the presence of clouds. Whether the TOMS AI should be regarded as a more reliable indicator of interannual variability depends on the extent of contamination by subpixel clouds.

In contrast to nonabsorptive or weakly absorbing aerosols, the dust reflectance significantly decreases from the NIR to the blue because of the absorption of mineral particles in the visible. We chose simple but realistic vertical structures for the dust layer and examined the applicability of a set of aerosol size distributions and refractive indices with radiative properties computed from Mie theory. We found that 18 models (six aerosol size-refractive index distributions times three aerosol vertical distributions) were general enough to estimate the dust reflectance in the visible with an absolute RMS error of the order of 5%. We show that these dust models can be used within a "spectral matching algorithm" [Gordon et al., 1997] to effect atmospheric correction of ocean color imagery in dust-contaminated regions. We also found that our models all produce very similar top-of-atmosphere outgoing visible flux but that this flux may be significantly different from that predicted by other conventional dust models.

Observations were performed from December 1997 to November 1998, including during the Kamaseen storms of March 1998. A ground-based, manual Sun photometer was used to measure aerosol optical thickness (tau (sub a ) ) at four spectral bands in the 340-870 nm wavelength range (namely 340, 440, 675, 870). Total precipitable water vapor (W) was also measured simultaneously, based on the 936 nm channel measurements and extrapolations of the aerosol optical thickness from the neighboring 675 and 870 nm channels. Aerosol optical thickness ra tau (sub a) all the four spectral bands were very high (averaging 2.0-4.0) during the Kamaseen storms of late March 1998. Correspondingly, the Aangstroem wavelength exponent alpha of the optical thickness fell close to zero during that time, implying a substantial increase in dust. Overall, the monthly mean and median aerosol optical thickness were highest during January-May and lowest in June-October. During the January-May period total precipitable water vapor and Aangstroem exponent were lower than during the June-October period. There is a high correlation between the Aangstroem exponent and the optical thickness (r=0.63), with a ranging from 0.0 to 0.5 for tau (sub a) > 1.0, indicating high dust concentration. Trajectory analysis shows that the presence of dust was associated with air masses arriving predominantly from the Sahara or North Africa. No significant correlation was found between the optical thickness and the precipitable water vapor. These basic systematic observations are vital for assessing dust climatology in this important part of the world and also for validating satellite observations and dust transport models.

Retrievals are performed over a comparison space of four-component mixtures, selected from six commonly observed components having assumed, fixed microphysical properties but with mixing ratios free to vary from 0% to 100%. We refer to this approach, which assumes climatologically probable component particles and derives aerosol mixtures from the observations, as a "climatological retrieval." On the basis of simulated Multiangle Imaging Spectroradiometer (MISR) observations over dark water, the retrieval can distinguish mixtures containing large, spherical particles (sea salt), nonspherical particles (accumulation and coarse mode dust), and small, dark particles (black carbon) to within 20% or better of each component's true mixing ratio. This is sufficient to distinguish maritime from continental aerosol air masses. The retrievals, which use all nine MISR angles and the two wavelengths least affected by ocean surface reflectance (672 and 867 nm), are not good at distinguishing medium, spherical, nonabsorbing (sulfate) from medium, spherical, absorbing (carbonaceous) particles. However, the sum is retrieved to within 20% of the true mixing ratio or better. This is significantly more detail about the properties of particle mixtures than has previously been retrieved from satellite data, and in all cases, the derived total column aerosol optical depth remains well constrained, to at least 0.05 or 20%, whichever is larger. We expect the MISR data, with its frequent global coverage, to complement in situ and field data, which can provide greater detail about aerosol size and composition locally. This combined effort should advance our knowledge of aerosol behavior globally and our ability to model the impact of aerosols on the climatically important solar radiation budget.

Most of the dust uplifted from these deserts is carried by trade winds and deposited in tropical oceans with very little, if any, transported to polar regions. During glacial periods the dust concentrations in polar ice cores were a factor of 10 to 100 higher than during interglacial periods, including the current Holocene. The early general circulation model simulations of the past glacial climate were not able to reproduce these high mineral dust concentrations; the most recent attempts achieve an increased dust transport to polar regions by extending dust source areas to higher latitudes. We present a hypothesis that during glacial periods the Hadley cell is confined closer to the equator. This contraction of the Hadley circulation leads to the geographical change of the boundary between the tropical and the midlatitude circulation regimes. During the glacial periods a considerable fraction of the current tropical deserts was located outside the region of the Hadley circulation. This allowed the dust to be uplifted and transported by midlatitude storm systems to the polar regions. We present a model for the contraction of the Hadley circulation during the past glacial periods based on the Schneider-Lindzen and Held-Hou model of symmetric tropical circulation and on the assumption that the tropical sea surface temperatures were lower during glacial periods than they are today.

Recent observations through surface network exhibit that Asian dust took place more often in the western part of the Korean peninsula over the last 20 years. In this study, two dust cases, April 1998 and January 1999, were selected to examine detailed conditions most favorable for dust generation, emission, and transport to Korea and to investigate the effect of dust particles on physical and optical properties of aerosols collected in Seoul. Dust transported to the Korean peninsula is closely linked to dust storms generated in upstream regions of the Yellow River or Manzurian plain, which are known as main source regions. Judged from synoptic conditions for both spring and winter dust events, meteorological settings favorable for dust emission are high surface winds and baroclinic instability at 1.5 km level. A strong wind belt, formed at a 5 km level, expedites dust transport, and this is typically much faster in winter. It was confirmed from a backward trajectory analysis that the air carrying mineral dust particles originated from deserts in central Asia and in 1 day passed through the Korean peninsula during wintertime. The effect of mineral dust on aerosol particles is well depicted in the size-separated number concentrations of aerosols observed in Seoul. In both cases, concentrations of coarse particles larger than 0.82 mu m were distinctly enhanced while those of fine particle smaller than 0.5 mu m were reduced. The measurements of optical depth also indicate that the atmosphere is more turbid with larger particles during dust events. Copyright 2001 by the American Geophysical Union.

The first one is that the aptitude of a soil to release particles smaller than 20 mu m depends on (1) the dry size distribution of aggregates constituting its loose fraction, (2) its roughness length, and (3) the wind velocity. The second implication is that the size distribution of aerosols released in source areas also strongly depends on these parameters. Copyright 2001 by the American Geophysical Union.

By evaluating and removing the variable background in a digital SEM image using dynamic thresholding and then calculating the area and perimeter of each particle, one can study the relationship between particle area and particle shape. It is possible to distinguish in this manner between at least two different particle populations, separated by their fractal dimension, in a set of samples collected during 1 day in a heavy dust storm in Israel.

This hemispherical transport of airborne dust took place during a series of storms that developed during the first three weeks of April in a background of low-index circulation. These repeated events are studied through the combined analyses and interpretation of atmospheric data, ground-based aerosol measurements, visibility observations, AVHRR and Meteosat visible band satellite data, and the results of Eta model simulations, including an aerosol transport component. The observations produce a consistent picture of the temporal and spatial development of the dust events, whose main features are used in parts to verify the model results. The rate of dust suspension from some areas of the western Sahara desert exceeded 1.5 mg m (super -2) h (super -1) and the maximum column integrated dust load reached 2 g m (super -2) during April 3-5 1994, when the first major suspension event produced two simultaneous pulses of dust moving in opposite directions across the subtropical Atlantic Ocean and the eastern Mediterranean Sea. These dust suspensions were created by surface winds resulting from subsidence on the northeastern side of a blocking anticyclone in the Atlantic region and subsequent winds of an intense developing cyclone in the Mediterranean-African region. In the following period, maximum dust loads of 4.5 and 2.5 g m (super -2) occurred on April 12 and 17, respectively, when new cyclones transported dust across the Mediterranean from Africa to Europe. The generation of the two dust pulses during the first even and the recurrent cyclone transport in the following period is shown to be the result of a large-scale, anomalous atmospheric circulation connected with blocking in the Atlantic Ocean and the interactions of upper air jets downstream of the blocking. The particular state of the hemispheric circulation during the studied period corresponded to the positive phase of the North Atlantic Oscillation (NAO). While previous statistical evidence has consistently linked dust transport in the region with the NAO signatures, we show the same connection on the basis of this case study.

This late April 1998 event coincided with an episode of photochemical smog and reduced dispersion in the Lower Fraser Valley (LFV). Filter samples in the region show a massive injection of crustal elements (Si, Fe, Al, and Ca) with concentrations of Si approximately double those previously recorded. Ratios of these elements to Fe are shown to be statistically similar to ratios observed in mineral aerosol events in Hawaii and China. On the basis of the difference between observed and expected elemental concentrations and reconstructed soil mass in the episode, it is estimated that Asian dust contributed 38-55% to observed PM (sub 10) in the LFV, the remainder being attributed to local sources. Comparison of the April 1998 event with two spring meteorological analogs is consistent with this estimate. Mesoscale model simulations suggest that mineral dust was incorporated into the planetary boundary layer as a result of strong subsidence over the interior of southern British Columbia and Washington State which permitted interception of lower tropospheric elevated aerosol layers by surface-based mixing processes over mountainous terrain. Surface easterly ("outflow") winds then transported this material into the Lower Fraser Valley where it contributed significantly to total particulate loadings and an intense haze. This mechanism is consistent with the observed spatial and temporal distribution of PM (sub 10) . Copyright 2001 by the American Geophysical Union.

It is based on the atmospheric response to dust, extracted from midday Meteosat-IR imagery, and takes advantage of the impact of dust aerosols on the thermal infra-red radiance outgoing to space. Simulations show a quasi-linear relationship between satellite response to dust and shortwave optical depth, with a sensitivity depending on particle size distribution and radiative surface properties. Comparison of measured satellite response with photometric optical depth agrees with the simulations. Water vapor significantly affects the satellite signal for cases of large columnar amounts and oceanic air masses advected inland. Hence apart from possible coastal effects, the water vapor effect can be neglected in the Sahelian-Saharan zone north of the Intertropical Convergence Zone, coinciding with the major regions of African dust emission and transport. The construction of the IDDI involves the processing of reference images, theoretically representing the outgoing radiance obtaining under clear-sky conditions. Errors may arise from (1) dust remaining in the reference images and (2) seasonal shifts of the reference level; however, the latter error will be offset by averaging used in climatological processing. An error budget is presented for the station of Gao. A statistical comparison of IDDI data with visibility measured at synoptic stations results in (1) a validation of the product, and (2) a climatologically relevant visibility-IDDI relation, valid for the arid regions of northern Africa. The latter relation is consistent with both simulations and photometric measurements. IDDI maps over Africa compare successfully with optical depth over adjacent ocean regions derived from Meteosat-VIS imagery. The observed continuity of dust plumes across the African coast demonstrates the consistency between both products. Copyright 2001 by the American Geophysical Union.

Huge Asian dust events that occurred in the middle of April 1998 were captured by this network. In this paper we present the organization of the network; a description of the instruments, including the lidar, sky radiometer, and optical particle counter; and the results of the observation, and offer discussions regarding the transport mechanism of Asian dust in east Asia using an on-line tracer model. We discussed the time series of the surface concentration and the height distribution of the dust. A cutoff cyclone generated during the dust episode was responsible for trapping and sedimentation during the transportation of the Asian dust, particularly in the southern parts of China and Japan. Horizontal dust images derived from NOAA/AVHRR clearly revealed the structure of the vortex. The lidar network observation confirmed the general pattern of dust height distribution in this event; the height of the major dust layer was about 3 km over Japan but was higher (4 to 5 km) in Seoul and Hefei. A thin dust layer in the upper troposphere was also commonly observed in Hefei and Japan. Evidence of the coexistence of dust and cirrus was shown by the polarization lidar. The lidar network observation of Asian dust and satellite remote sensing provide key information for the study of the transport mechanism of Asian dust. Further extension of the lidar network toward the interior of the continent and the Pacific Rim would reveal the greater global mechanism of the transportation.

We derive (1) the dust size distribution, showing a dominant coarse mode at 1-5 mu m and a secondary mode around 0.5 mu m effective radius; (2) dust absorption, which is found to be substantially smaller than reported from previous measurements; (3) the real part of the refractive index which varies within the range 1.53-1.46; and we show that (4) the effect of the dust nonspherical shape on its optical properties is not significant for scattering angles <120 degrees .

The analysis shows that the particles were mostly aggregates of varying mineralogical composition rather than pure minerals. It is also shown that sulfur (not associated with gypsum) and, to a lesser extent, iron tended to reside on the particles' surface, while Ca, Mg, K, Al, and Si were all an integral part of the particles. The lack of NaCl and sulfuric acid aerosols in the sample indicates that the air mass did not interact with marine air or with clouds. This conclusion is further supported by back trajectory calculations. These findings suggest that the sulfur in the aerosols did not result from atmospheric processes but rather originated from processes in the source region. Black residue, surrounding some of the particles, suggests the possible existence of organic matter in the sample, probably originating from biological activity in the soil at the source of the particles. The method of individual particle analysis provides important information about the composition and morphology of the particles, information that otherwise cannot be obtained by bulk analysis methods.

In addition, the deposition flux of dustfall was measured throughout Israel and in the Sinai Desert during the years 1970-1973. TSP concentrations during dust pulses ("episodes") were from 10 to 120 times higher than the background values of approximately 100 mu g m (super -3) ; the maximum concentration measured was 24,000 mu g m (super -3) . The annual deposition flux (from pulses only) decreased from 90 g m (super -2) yr (super -1) in the south to 30 g m (super -2) yr (super -1) in the north. The local contribution to the annual deposition flux was approximately 50% in the south and near the Judean Desert in the east but decreased to 25% in the north. Deposition velocities of the dustfall during months without dust episodes were on the order of 1.0 cm s (super -1) , while during months when dust storms occurred, deposition velocities are from 2 to 6 times greater than the background, depending on the location. Monthly mean deposition velocities during dust episodes varied between 2.6 cm s (super -1) and 9.0 cm s (super -1) ; short term (1 hour) values up to 27 cm s (super -1) have been measured.

Time series over Algeria, Libya, and Israel yield the following findings: The peak values in both surface concentrations and TOMS data suggest that AI values of 2.5 and 1.2 correspond to surface mean daily concentrations of 1900 and 1000 mu g/m (super 3) respectively. Surface concentrations and TOMS maps show that AI values of 3.0 correspond to about 4000 mu g/m (super 3) . TOMS AI maximum values were found to increase from Algeria to Israel moving along with the center of the dust plume from 0.9 to 2.1 and 2.5 AI values. This seems to be in contradiction with the fact that the plume moves farther away from the major mineral dust sources over the Sahara and may be caused by either an increased vertical extension of the plume, hence increasing the TOMS AI, or due to convergence of the dust plume over the eastern Mediterranean. The size distribution, morphological, and mineralogical composition of the dust analyzed in this study, as well as other aerosol parameters, are essential for improving the remote sensing methods such as the TOMS AI algorithms. Of course, surface measurements alone do not allow the refinement of the TOMS retrievals; vertical profile dust measurements as well as other physical and optical aerosol parameters are necessary.

Data from the broadband radiometers suggests that the perturbation to the top of the atmosphere net solar irradiance is as strong as -60 W m (super -2) + or -5 W m (super -2) during the dust events. In situ measurements with the nephelometer and particle soot absorption photometer suggest that the single scattering albedo is approximately 0.87 at a wavelength of 0.55 mu m. This is in agreement with the optical parameters calculated from independent measurements of the particle size distributions combined with suitable refractive indices and Mie-scattering theory. The wavelength dependence of the extinction coefficient derived from measurements of the scattering coefficient by the nephelometer is also in excellent agreement with the calculations. Independent surface-based measurements from Cape Verde suggest that the wavelength dependence of the aerosol optical depth appears reasonable. Calculations of the downward solar irradiances within the aerosol layer are generally in good agreement with the measurements demonstrating consistency between the measurements and the modeling efforts. The terrestrial radiative effect is not detectable by the current instrumentation, though it cannot be considered negligible. These measurements suggest that satellite retrieval algorithms may misclassify the aerosol outbreak as cloud because the aerosol optical depth at 0.55 mu m is as high as 1.15, which is in excess of the thresholds used in some cloud detection algorithms. The measurements demonstrate that this method could be used to provide an accurate benchmark for satellite-based estimates of the radiative effect of aerosols.

The study covers a 2-week period of strong dust storms in April 1998 in the major dust source area of East Asia. The modeled surface winds at grid resolutions of 20, 40, 60, and 80 km are verified against observational data. At all resolutions the model has a positive bias in wind speed that decreases as resolution increases. Dust fluxes that are proportional to the fourth power of the friction velocity (u (sub *) ) and the third power of the wind speed are calculated at all four resolutions and compared. Compared with the 20-km resolution u (sub *) -driven flux, which is deduced to be the most accurate, the u (sub *) -driven flux on the coarser grids overestimate the flux, with the 80 km being 60% higher for individual events and nearly 20% higher in the total dust production for the entire study period. The wind-driven flux misses the smaller events due to the lack of a dependence on stability and wind shear, when compared with the timing of surface dust observations, and has differences of up to 70%, when compared with the 20-km u (sub *) -driven flux. Averaging over space and time tends to reduce the differences among grids and might support modeling at coarse resolution. Copyright 2001 by the American Geophysical Union.

As part of the largest remaining area of intact deciduous tropical forest in the world, it has been nominated a priority area for conservation by several environmental organizations. We quantified the spatial and temporal patterns of deforestation in the area by digital processing of high-resolution satellite imagery from 1975 through 1998. The estimated rate of deforestation was among the highest in the world for such a limited area, ranging from 160 km super(2)/year in the early1980s to almost 1200 km super(2)/year in the late 1990s. Although most deforestation up to 1984 was in Bolivian peasant and Mennonite colonies, most deforestation after 1984 was in non-Mennonite industrial soybean farms. The level of fragmentation of uncut forest, caused by the spatial patterns of deforestation, also differed among these broad land-use types. Deforestation in planned and spontaneous peasant colonies was complex in shape, forming relatively large areas of edge-affected forest, whereas that in Mennonite and other industrial farms was in large, rectangular increments, creating relatively less edge. But the distribution of these farms and the practice of initially clearing around the peripheries of properties resulted in the isolation of large areas of forest. In 1998 four-fifths of the remaining forest were either within 1 km of a clearance edge or in isolated fragments of <50 km super(2). Compared with deforested areas, the areas of isolated and edge-affected forest were disproportionately large during the early stages of frontier colonization. These results imply that if the fragmentation effects of deforestation are to be minimized, conservation planning must occur at the earliest stages of frontier development.

Remotely sensed microwave radiobrightness observations can cover large scales but have limited resolution and are only indirectly related to the hydrologic variables of interest. We describe a four-dimensional (4-D) variational assimilation algorithm that makes best use of available information while accounting for both measurement and model uncertainty. The representer method used here is more efficient than a Kalman filter because it avoids explicit propagation of state error covariances. In a synthetic example, which is based on a field experiment, we demonstrate estimation performance by examining data residuals. Such tests provide a convenient way to check the statistical assumptions of the approach and to assess its operational feasibility. Internally computed covariances show that the estimation error decreases with increasing soil moisture. An adjoint analysis reveals that trends in model errors in the soil moisture equation can be estimated from daily L-band brightness measurements, whereas model errors in the soil and canopy temperature equations cannot be adequately retrieved from daily data alone. Nonetheless, state estimates obtained from the assimilation algorithm improve significantly on prior model predictions derived without assimilation of radiobrightness data.

Previous modelling studies have concluded that major shifts in vegetation patterns, including changes in boreal forest extent, could arise during the next two centuries under global warming scenarios. However, field investigations of tree stands at ecotones have so far revealed little indication of stand response to warming during the last 100 years. This study uses a c. 25-year record of Landsat satellite observations to quantify changes in forest stand extent in two areas of northern Canada. Two regions of northern Canada, near Richmond Gulf, Quebec, and Great Slave Lake, north-west Territories. Normalized-difference vegetation index (NDVI) plots across forest-tundra boundaries were obtained from radiometrically corrected Landsat imagery acquired during the 1970s and 1990s. These curves were evaluated to look for changes over the c. 25-year period related to forest stand expansion. Although forest-tundra boundaries could be clearly mapped from the satellite data, no obvious change in forest boundaries was apparent during the duration of the image time series, constraining recent geographical expansion rates to <200-300 m per century. Also, no evidence for local expansion of forest stands (e.g. within sheltered valleys) was found. The results are consistent with field observations, and suggest that, at the moment, boreal forest extents remain basically stable. This may reflect inherent lags between forest response and climate change, or competitive pressures between tree stands and surrounding tundra and herbaceous vegetation.

The procedure is tested with historical 6.6 GHz H and V polarized brightness temperature observations from the scanning multichannel microwave radiometer (SMMR) over several test sites in Illinois. Results using only nighttime data are presented at this time due to the greater stability of nighttime surface temperature estimation. The methodology uses a radiative transfer model to solve for surface soil moisture and vegetation optical depth simultaneously using a nonlinear iterative optimization procedure. It assumes known constant values for the scattering albedo and roughness, and that vegetation optical depth for H-polarization is the same as for V-polarization. Surface temperature is derived by a procedure using high frequency V-polarized brightness temperatures. The methodology does not require any field observations of soil moisture or canopy biophysical properties for calibration purposes and may be applied to other wavelengths. Results compare well with field observations of soil moisture and satellite-derived vegetation index data from optical sensors.

This data source is now more accessible because of improvements in digitizing technology, Internet file transfer, and availability of image processing software. We present three examples of conservation-related projects that benefited from the use of astronaut photographs. First, NASA scientists requested that astronauts photograph the area of the controversial Isahaya Bay reclamation project in Japan. Japanese researchers used photographs from before and after the reclamation as a tool for communication with the public about the effects of tidal-flat loss. The newly acquired images and the availability of high-resolution digital images from NASA archives provided timely public information on the observed changes. Second, we digitally classified and analyzed a Space Shuttle photograph of Chobe National Park in Botswana to identify the locations of woodlands affected by elephants. Field validation later confirmed that areas identified on the image showed evidence of elephant damage. Third, we used a summary map from intensive field surveys of seagrasses in Shoalwater Bay, Australia, as reference data for a supervised classification of a digitized photograph taken from orbit. The classification distinguished seagrasses, sediments, and mangroves with accuracy approximating that in studies using other satellite remote-sensing data. Astronaut photographs are in the public domain, and the database of nearly 400,000 photographs from the late 1960s to the present is available at a single searchable location on the Internet (http://eol.jsc.nasa.gov/sseop). These photographs can be used by conservation biologists as a source of general information about the landscape and for quantitative mapping.

Our study addresses the use of trends in solar UV-B radiation exposure (280-320 nm) at these sites over the last two decades, derived from the Total Ozone Mapping Spectrometer satellite data. It is intended to demonstrate a role for satellite observations in determining whether UV-B radiation is a contributing factor in amphibian declines. We used these data to calculate the daily erythemal (sunburning) UV-B, or UV-B , exposure at the latitude, longitude, and elevation of each of 20 survey sites. The annually averaged UV-B dose, as well as the maximum values, have been increasing in both Central and South America, with higher levels reached at the Central American sites. The annually averaged UV-B exposure increased significantly from 1979-1998 at all 11 Central American sites we examined (r super(2) = 0. 60-0. 79; p less than or equal to 0. 015), with smaller but significant increases at five of the nine South American sites (r super(2) = 0. 24-0. 42; p less than or equal to 0. 05). The number of days having the highest UV-B exposure ( greater than or equal to 6. 75 kJ/m super(2)/day) increased in both regions from <40 days per year to approximately 58 days per year in 1998 (r super(2) = 0. 24-0. 42; p less than or equal to 0. 001). In Central America, the contribution of these very high UV-B exposure levels to the annual UV-B total increased from approximately 5 to approximately 15% over the 19-year period, but actual daily exposures for each species are unknown. A UV-B ratio, the highest monthly UV-B exposure relative to the annual average for the highest UV-B category ( greater than or equal to 6. 75 kJ /m super(2)), increased in both regions over this time period (r super(2) = 0. 73; p less than or equal to 0. 001). This UV index was consistently higher for Central America, where species declines have been the most severe. These results should justify further research into whether UV-B radiation plays a role in amphibian population declines and extinctions. We discuss synergy among UV-B radiation and other factors, especially those associated with alterations of water chemistry (e. g. , acidification) in aqueous habitats.

All recent vegetation surveys have been based on optical satellite data, which is hampered by cloud cover and by southern Bahia's intricate mix of forest patches with other tree crops, especially cocoa. We describe the application of radar remote-sensing data to distinguish forest patches from cocoa planted in the shade of natural-forest trees. Radar, unlike optical sensors, is not obstructed by cloud cover and can acquire information about forest structure by penetrating into the vegetation canopy. The vegetation map generated from radar data clearly separates forest patches based on the degree of structural disturbance such as the density of shaded trees, the openness of the canopy, and the density of the monodominant Erythyrina shaded trees. The structural classification based on the radar data, and shown on the map, can help researchers assess the degree of fragmentation of the original Atlantic coastal forest and delineate areas of less disturbance with higher potential for conservation of biodiversity. This information can then be applied to conservation planning, especially the design and monitoring of nature reserves and the modeling of biological corridors.

Much of this new productivity probably occurred in microbial mats, which incorporate a range of photosynthetic and anaerobic microorganisms in extremely close physical proximity. The potential contribution of these systems to global biogeochemical change would have depended on the nature of the interactions among these mat microorganisms. Here we report that in modern, cyanobacteria-dominated mats from hypersaline environments in Guerrero Negro, Mexico, photosynthetic microorganisms generate H sub(2) and CO--gases that provide a basis for direct chemical interactions with neighbouring chemotrophic and heterotrophic microbes. We also observe an unexpected flux of CH sub(4), which is probably related to H sub(2)-based alteration of the redox potential within the mats. These fluxes would have been most important during the nearly 2-billion-year period during which photosynthetic mats contributed substantially to biological productivity--and hence, to biogeochemistry--on Earth. In particular, the large fluxes of H sub(2) that we observe could, with subsequent escape to space, represent a potentially important mechanism for oxidation of the primitive oceans and atmosphere.

AN - 71264789; 11858255 AB - There is considerable interest in developing silicon-based telescopes because of their compactness and low power requirements. Three such telescopes have been flown on board the Space Shuttle to measure the linear energy transfer spectra of trapped, galactic cosmic ray, and solar energetic particles. Dosimeters based on single silicon detectors have also been flown on the Mir orbital station. A comparison of the absorbed dose and radiation quality factors calculated from these telescopes with that estimated from measurements made with a tissue equivalent proportional counter show differences which need to be fully understood if these telescopes are to be used for astronaut radiation risk assessments. Instrument performance is complicated by a variety of factors. A Monte Carlo-based technique was developed to model the behavior of both single element detectors in a proton beam, and the performance of a two-element, wide-angle telescope, in the trapped belt proton field inside the Space Shuttle. The technique is based on: (1) radiation transport intranuclear-evaporation model that takes into account the charge and angular distribution of target fragments, (2) Landau-Vavilov distribution of energy deposition allowing for electron escape, (3) true detector geometry of the telescope, (4) coincidence and discriminator settings, (5) spacecraft shielding geometry, and (6) the external space radiation environment, including albedo protons. The value of such detailed modeling and its implications in astronaut risk assessment is addressed. c2001 Elsevier Science B.V. All rights reserved.

AN - 71329894; 12194178 AB - This paper presents a wireless, remote query ammonia sensor comprised of a free-standing magnetoelastic thick-film coated with a polymer, poly(acrylic acid-co-isooctylacrylate), that changes mass in response to atmospheric ammonia concentration. The mass of the polymer layer modulates the resonant frequency the ferromagnetic magnetoelastic substrate, hence by monitoring the frequency response of the sensor, atmospheric NH3 concentration can be determined remotely, without the need for physical connections to the sensor or specific alignment requirements. The effect of copolymer composition, polymer film thickness, and relative humidity level (RH) on the sensitivity of the sensor were investigated. The sensor linearly tracks ammonia concentration below 0.8 vol.%, and tracks higher concentrations logarithmically; within the linear calibration range, a 0.02 vol.% change in NH3 concentration can be detected. c2001 Elsevier Science B.V.

AN - 71395373; 12638609 AB - It is an intriguing question whether gravity-changing stress modulates human cell mutability. To resolve this problem, it is necessary to determine the cellular events leading to modulation. We previously detected protease activation just after UV (UVC, principally 254 nm wavelength) irradiation followed by hypomutability in cultured human cells. We here investigated whether UV-activated protease activity is affected in human UVAP-1 cells exposed to gravity-changing stress prior to UV irradiation.

AN - 71372522; 12638607 AB - We adopted a simple experimental framework to follow the dependence of structural aberrations and the modifications in selected metabolic processes correlated with the exposure of cells to microgravity. Alterations to the cellular metabolism induced by exposure to microgravity are evidentiated in the modification of PARP activity (strongly dependent to the presence of DNA damages and to the altered gene expression), in the modification of the repair ability and in the cell's energy homeostasis (NAD and ATP). Cells are exposed continuously to microgravity in a Random Positioning Machine (RPM) in complete medium for 48 hours. At the end of this period a part of these cells are immediately analysed for the parameters reported above and the remaining were furtherly incubated in standard laboratory conditions to document eventual defects during the phases of the recovery process. A part of cells, just after exposure to microgravity, were also subjected to treatment with a strong damaging agent, KBrO3, and these cells were subsequently analyzed. This final treatment was meant to amplify the eventual deficiencies experienced by microgravity-exposed cells in the DNA repair process also in dependence with the alterated metabolic conditions resulting after the exposure to microgravity.

AN - 71335356; 12448420 AB - The green fluorescent protein (GFP) from the jellyfish Aequorea victoria has proven to be a powerful tool in plant genetic transformation studies. This paper reviews the history and the progression of the expression of GFP variants in transgenic plants. The distinguishing features of the most useful GFPs, such as those including the S65T chromophore mutation and those with dual excitation peaks, are discussed. The review also focuses on the utility of GFP as a visual selectable marker in aiding the plant transformation process; GFP has been more important in monocot transformation compared with dicot transformation. Finally, the potential utility of new fluorescent proteins is speculated upon.

The computer-controlled system consisted of a motorized turntable to present the plants to the stationary sensors and reduce microclimate variability among the plants. Major sensing capabilities of the system included machine vision, infrared thermometry, time domain reflectometry, and micro-lysimeters. The system also maintained precise growth-medium moisture levels through a computer-controlled drip irrigation system. The system was capable of collecting required data continuously to monitor and to evaluate the plant health and growth. JF - Transactions of the ASAE.

(Hadean), and 3800-2500 m.y. (Archaean), with atmosphere compositions ranging from mainly anoxic CO (sub 2) to mainly N (sub 2) . As atmosphere CO (sub 2) decreased over the Archaean period, it is suggested that the production of nitric oxide from lightning discharge decreased by two orders of magnitude until 2200 m.y.

Some of these have been found to be non-racemic, but the indigenous nature of their L-enantiomeric excesses has been subject to debate in view of possible terrestrial contamination. We have investigated two amino acids of common terrestrial and meteoritic occurrence, alanine and glutamic acid, and assessed their indigenous enantiomeric ratios in the Murchison and Murray meteorites through the ratios of some of their derivatives. Analyzed were N-acetyl alanine, alpha -imino propioacetic acid, N-acetyl glutamic acid and pyroglutamic acid. Both alanine derivatives were found to be racemic, while those of glutamic acid showed L-enantiomeric excesses varying from 16% to 47.2% for pyroglutamic acid, and from 8.6% to 41% for N-acetyl glutamic acid. The delta (super 13) C was determined for the two enantiomers of Murchison pyroglutamic acid both before and after acid hydrolysis to glutamic acid. The values of +27.7 per mil (D-pyro), +10.0 per mil (L-pyro), +32.2 per mil (D-glu) and +14.6 per mil (L-glu) were obtained. The racemic nature of alanine derivatives strongly suggests that alanine itself, as indigenous to the meteorite, is racemic. The explanation of the L-enantiomeric excesses found for glutamic acid derivatives is less direct; however, the variability of the enantiomeric ratios for these compounds and the distinctly lower delta (super 13) C values determined for pyroglutamic L-enantiomer point to a terrestrial contamination, possibly dating to the time of fall.

To test whether impacts can excavate core iron and mix it with crustal material, we used a low-resolution, smoothed-particle hydrodynamics computer simulation. For 50-300 km diameter differentiated targets, we found that significant proportions of scrambled core material (and hence potential mesosiderite metal material) could be generated. For near-catastrophic impacts that reduce the target to 80% of its original diameter and about half of its original mass, the proportion of scrambled core material would be about 5 vol%, equivalent to approximately vol% of mesosiderite-like material. The paucity of olivine in mesosiderites and the lack of metal-poor or troilite-rich meteorites from the mesosiderite body probably reflect biased sampling. Mesosiderites may be olivine-poor because mantle material was preferentially excluded from the metal-rich regions of the reaccreted body. Molten metal globules probably crystallized around small, cool fragments of crust hindering migration of metal to the core. If mantle fragments were much hotter and larger than crustal fragments, little metal would have crystallized around the mantle fragments allowing olivine and molten metal to separate gravitationally. The rapid cooling rates of mesosiderites above 850 degrees C can be attributed to local thermal equilibration between hot and cold ejecta. Very slow cooling below 400 degrees C probably reflects the large size of the body and the excellent thermal insulation provided by the reaccreted debris. We infer that our model is more plausible than an earlier model that invoked an impact at approximately 1 km/s to mix projectile metal with target silicates. If large impacts cannot effectively strip mantles from asteroidal cores, as we infer, we should expect few large eroded asteroids to have surfaces composed purely of mantle or core material. This may help to explain why relatively few olivine-rich (A-type) and metal-rich asteroids (M-type) are known. Some S-type asteroids may be scrambled differentiated bodies.

CO (sub 2) , CH (sub 4) , and N (sub 2) O concentrations over this period are established on the basis of fossil air trapped in ice cores and instrumental measurements over the last few decades. Estimates of solar irradiance, ranging between 1364.2 and 1368.2 W/m (super 2) , are presented using calibrated observations of the Sun back to 1610 and cosmogenic isotope variations extending back to 1500. Troposheric aerosol distributions are calculated by scaling the modern distribution of sulfate and carbonaceous aerosol optical depths back to 1860 using reconstructed regional CO (sub 2) emissions with anthropogenic emissions assumed to be zero prior to 1860. The first continuous, annually dated record of zonally averaged srtatospheric (volcanic) optical depths back to 1500 is constructed using sulfate flux data from multiple ice cores from both Greenland and Antarctica, in conjunction with historical and instrumental (satellite and purheliometric) observations. Climate forcings generated are applied to a suite of transient paleoclimate models for the past 500 years. (Mod. auth. abstr.)

A subset of chondrules from each chondrite was chosen for analysis by a scanning electron microscope equipped with an energy dispersive x-ray spectrometer prior to high-precision Cr-isotopic analyses. (super 53) Cr/ (super 52) Cr correlates with (super 55) Mn/ (super 52) Cr to give initial ( (super 53) Mn/ (super 55) Mn) (sub I) = (9.4+ or -1.7)X10 (super -6) for Chainpur chondrules and ( (super 53) Mn/ (super 55) Mn) (sub I) = (9.5+ or -3.1)X10 (super -6) for Bishunpur chondrules. The corresponding chondrule formation intervals are, respectively, Delta t (sub LEW) = -10+ or -1 Ma for Chainpur and -10+ or -2 Ma for Bishunpur relative to the time of igneous crystallization of the Lewis Cliff (LEW) 86010 angrite. Because Mn/Sc correlates positively with Mn/Cr for both the Chainpur and Bishunpur chondrules, indicating dependence of the Mn/Cr ratio on the relative volatility of the elements, we identify the event dated by the isochrons as volatility-driven elemental fractionation for chondrule precursors in the solar nebula. Thus, our data suggest that the precursors to LL chondrules condensed from the nebula 5.8+ or -2.7 Ma after the time when initial ( (super 53) Mn/ (super 55) Mn) (sub I) = (2.8+ or -0.3)X10 (super -5) for calcium-aluminum-rich inclusions (CAIs), our preferred value, determined from data for (a) mineral separates of type B Allende CAI BR1, (b) spinels from Efremovka CAI E38, and (c) bulk chondrites. Mn-Cr formation intervals for meteorites are presented relative to average I(Mn) = ( (super 53) Mn/ (super 55) Mn) (sub Ch) = 9.46+ or -10 (super -6) for chondrules. Mn/Cr ratios for radiogenic growth of (super 53) Cr in the solar nebula and later reservoirs are calculated relative to average (I(Mn), epsilon ( (super 53) Cr) (sub I) ) = ((9.46+ or -0.08)X10 (super -6) , -0.23+ or -0.08) for chondrules. Inferred values of Mn/Cr lie within expected ranges. Thus, it appears that evolution of the Cr-isotopic composition can be traced from condensation of CAIs via condensation of the ferromagnesian precursors of chondrules to basalt generation on differentiated asteroids. Measured values of epsilon ( (super 53) Cr) for individual chondrules exhibit the entire range of values that has been observed as initial epsilon ( (super 53) Cr) values for samples from various planetary objects, and which has been attributed to radial heterogeneity in initial (super 53) Mn/ (super 55) Mn in the early solar system. Estimated (super 55) Mn/ (super 52) Cr = 0.42+ or -0.05 for the bulk Earth, combined with epsilon ( (super 53) Cr) = 0 for the Earth, plots very close to the chondrule isochrons, so that the Earth appears to have the Mn-Cr systematics of a refractory chondrule. Thus, the Earth apparently formed from material that had been depleted in Mn relative to Cr contemporaneously with condensation of chondrule precursors. If, as seems likely, the Earth's core formed after complete decay of (super 53) Mn, there must have been little differential partitioning of Mn and Cr at that time.

In Brazil the dust outbreak produced an increase of a factor of 3 in the daily mean mass concentration (up to 26 + or - 7 mu g m (super -3) ) of particles smaller than 10 mu m equivalent aerodynamic diameter (EAD), and in the daily mean aerosol particle scattering coefficient sigma (sub s) (up to 26 + or - 8 Mm (super -1) STP, ambient humidity). Background levels of aerosol scattering (ambient) were sigma (sub s) approximately 10 Mm (super -1) . The effect of dust advection was evident for all major crustal elements (Al, Si, Ca, Ti, Mn, and Fe), as well as the sea-salt elements (Na, Cl, and S), as the dust layer was transported at low altitude (below 800 hPa). Coarse P and organic carbon (OC) concentrations were not influenced by the occurrence of dust, and were mainly emitted by the rain forest. The dry scattering mass efficiency of dust (particles smaller than 10 mu m EAD) was estimated to be between 0.65 (+ or - 0.06) and 0.89 (+ or - 0.08) m (super 2) g (super -1) . Airborne profiles of aerosol scattering showed two distinct types of vertical structure in the dust layer over Suriname, either vertically uniform (15, 26 March), or plume-like (25 March). Dust layers extended generally up to 700 hPa, while scattering layers occasionally encountered at higher altitudes resulted from smoke emitted by biomass burning in Venezuela and Colombia. Observations in South America were supported by measurements in Israel and Tenerife (Canary Islands), where the dust outbreaks were also detected. Copyright 2001 by the American Geophysical Union.

In this paper we specifically address the question of whether or not water vapor finds a substantial diurnal reservoir in the Martian regolith. To address this issue, we have measured H (sub 2) O adsorption kinetics on SWy-1, a Na-rich montmorillonite from Wyoming. The highest-temperature (273 K) data equilibrate rapidly. Data gathered at realistic H (sub 2) O partial pressures and temperatures appropriate to early morning show two phenomena that preclude a significant role for smectites in diurnally exchanging a large column abundance. First, the equilibration timescale is longer than a sol. Second, the equilibrium abundances are a small fraction of that predicted by earlier adsorption isotherms. The explanation for this phenomenon is that smectite clay actually increases its surface area as a function of adsorptive coverage. At Mars-like conditions we show that the interlayer sites of smectites are likely to be unavailable. Copyright 2001 by the American Geophysical Union.

Three different model experiments are used with climatological surface forcing appended by wind stress and/or buoyancy flux anomalies. The simulated SSH and gyre circulation and altimeter data are analyzed using the empirical orthogonal function analysis. It is shown that decadal variability in the leading SSH and gyre circulation mode originates from the basin-scale thermal forcing component, not from wind stress driving. This means that low-frequency variations of SSH along the Gulf Stream reflect predominantly overturning changes. The horizontal gyre circulation changes are also related to the overturning due to the topography which couples baroclinic and barotropic flows. SSH variability outside the western boundary current region, on the eastern side of the North Atlantic basin, is determined by local and remote (Rossby waves) wind stress forcing. The model simulations and altimeter data suggest that there was a large SSH change in 1995-1996 over the Gulf Stream which was associated with an abrupt weakening of the overturning.

While sensor development has made considerable headway for fire monitoring with the recent launch of Terra in late 1999 and upcoming missions such as bispectral infrared detection (BIRD), FOCUS, and the National Polar-Orbiting Operational Environmental Satellite System (NPOESS), the retrieval of fire properties from satellite observations remains problematic. Current methods for determining properties of actively burning fires, for example, continue to be based on a simple two-component model developed by Dozier in 1981. Its limitations in terms of reliable operational fire property retrieval have been known for some time, although not examined in detail to date. With new measurements from recently deployed and evolving satellite systems, which offer key advantages for fire remote sensing, it is appropriate now to more comprehensively examine the heritage methodology for fire property retrieval. The results of a sensitivity analysis indicate that under realistic conditions the random errors in fire temperature and area retrieved using Dozier's method are plus or minus 100 K and plus or minus 50% at one standard deviation, respectively, for fires occupying a pixel fraction greater than 0.005 (this corresponds to a 5000-m super(2) fire within a 1-km pixel). For smaller active fires, larger random and systematic errors are likely to occur.

Witness plates made up of spacecraft materials, some painted with spacecraft qualified paints, were exposed for approximately 7 to 9 months at JPL-SAF and examined the particulate materials collected for the incidence of total cultivable aerobic heterotrophs and heat-tolerant (80 degree C for 15-min.) spore-formers. The results showed that the witness plates coated with spacecraft qualified paints attracted more dust particles than the non-coated stainless steel witness plates. Among the four paints tested, witness plates coated with NS43G accumulated the highest number of particles, and hence attracted more cultivable microbes. The conventional microbiological examination revealed that the JPL-SAF harbors mainly Gram-positive microbes and mostly spore-forming Bacillus species. Most of the isolated microbes were heat resistant to 80 degree C and proliferate at 60 degree C. The phylogenetic relationships among 23 cultivable heat-tolerant microbes were examined using a battery of morphological, physiological, molecular and chemotaxonomic characterizations. By 16S rDNA sequence analysis, the isolates fell into seven clades: Bacillus licheniformis, B. pumilus, B. cereus, B. circulans, Staphylococcus capitis, Planococcus sp. and Micrococcus lylae. In contrast to the cultivable approach, direct DNA isolation, cloning and 16S rDNA sequencing analysis revealed equal representation of both Gram-positive and Gram-negative microorganisms.

The findings suggest three recurring rainfall-SST coupled modes. Characterized by a pronounced biennial variability, the first mode is associated with generally depressed rainfall over the western Pacific and the "Maritime Continent," stemming from the eastward shift of the Walker circulation during the growth phase of El Nino. The associated SST pattern consists of an east-west SST seesaw across the Pacific and another seesaw with opposite polarity over the Indian Ocean. The second mode is associated with a growing La Nina, comprising mixed, regional, and basin-scale rainfall and SST variability with abnormally warm water in the vicinity of the Maritime Continent and western Pacific. It possesses a pronounced low-level west Pacific anticyclone (WPA) near the Philippines and exhibits large subseasonal-scale variability. The third mode is associated with regional coupled ocean-atmosphere processes in the ASM region, having spatial and temporal variabilities that suggest extratropical linkages and interhemispheric interactions occurring on decadal timescales. Results indicate the importance of regional processes in affecting ASM rainfall variability. On the average, and over the ASM region as a whole, ENSO-related basin-scale SSTs can account for about 30% of the variability, and regional processes can account for an additional 20%. In individual years and over subregions, the percentages can be much higher or lower. In addition to the shift in the Walker circulation, it is found that the regional excitation of the WPA is important in determining the rainfall variability over south Asia and east Asia. Based on the results, a hypothesis is proposed that anomalous wind forcings derived from the WPA may be instrumental in inducing a biennial modulation to natural ENSO cycles. The causes of the 1997 and 1998 rainfall anomalies over the ASM subregions are discussed in the context of these results and in light of recent observations of long-term changes in the monsoon-ENSO relationship.

Strain SH-94-5, a Naturally Occurring Cyanobacterium Deficient in Nitrate Assimilation AN - 18076261; 5146269 AB - Synechococcus sp. strain SH-94-5 is a nitrate assimilation-deficient cyanobacterium which was isolated from an ammonium-replete hot spring in central Oregon. While this clone could grow on ammonium and some forms of organic nitrogen as sole nitrogen sources, it could not grow on either nitrate or nitrite, even under conditions favoring passive diffusion. It was determined that this clone does not express functional nitrate reductase or nitrite reductase and that the lack of activity of either enzyme is not due to inactivation of the cyanobacterial nitrogen control protein NtcA. A few other naturally occurring cyanobacterial strains are also nitrate assimilation deficient, and phylogenetic analyses indicated that the ability to utilize nitrate has been independently lost at least four times during the evolutionary history of the cyanobacteria. This phenotype is associated with the presence of environmental ammonium, a negative regulator of nitrate assimilation gene expression, which may indicate that natural selection to maintain functional copies of nitrate assimilation genes has been relaxed in these habitats. These results suggest how the evolutionary fates of conditionally expressed genes might differ between environments and thereby effect ecological divergence and biogeographical structure in the microbial world.

The small cytochrome was completely sequenced, and the genes coding for both proteins were cloned and sequenced. The small cytochrome c contains 91 residues and four heme binding sites. It is most similar to the cytochromes c from Shewanella frigidimarina (formerly Shewanella putrefaciens) NCIMB400 and the unclassified bacterial strain H1R (64 and 55% identity, respectively). The amount of the small tetraheme cytochrome is regulated by anaerobiosis, but not by fumarate. The larger of the two low-potential cytochromes contains tetraheme and flavin domains and is regulated by anaerobiosis and by fumarate and thus most nearly corresponds to the flavocytochrome c-fumarate reductase previously characterized from S. frigidimarina to which it is 59% identical. However, the genetic context of the cytochrome genes is not the same for the two Shewanella species, and they are not located in multicistronic operons. The small cytochrome c and the cytochrome domain of the flavocytochrome c are also homologous, showing 34% identity. Structural comparison shows that the Shewanella tetraheme cytochromes are not related to the Desulfovibrio cytochromes c sub(3) but define a new folding motif for small multiheme cytochromes c.

Multiple satellite rainfall estimates combined with gauge observations allow for a quantitative analysis of precipitation anomalies in the tropics and elsewhere accompanying the 1997-1999 ENSO cycle. An examination of the evolution of the El Nino and accompanying precipitation anomalies revealed that a dry Maritime Continent (MC) preceded the formation of positive sea-surface temperature (SST) anomalies in the eastern Pacific Ocean. Thirty- to sixty-day oscillations in the winter of 1996-1997 may have contributed to this lag relationship. Furthermore, westerly wind burst events may have maintained the drought over the MC. The warming of the equatorial Pacific was then followed by an increase in convection. A rapid transition from El Nino to La Nina occurred in May 1998, but as early as October-November 1997, precipitation indices captured substantial changes in Pacific rainfall anomalies. The global precipitation patterns for this event were in good agreement with the strong consistent ENSO-related precipitation signals identified in earlier studies. Differences included a shift in precipitation anomalies over Africa during the 1997-1998 El Nino and unusually wet conditions over northeast Australia during the later stages of the El Nino. Also, the typically wet region in the north tropical Pacific was mostly dry during the 1998-1999 La Nina. Reanalysis precipitation was compared with observations during this time period and substantial differences were noted. In particular, the model had a bias towards positive precipitation anomalies and the magnitudes of the anomalies in the equatorial Pacific were small compared with the observations. Also, the evolution of the precipitation field, including the drying of the MC and eastward progression of rainfall in the equatorial Pacific, was less pronounced for the model compared with the observations.

Initially, thin (normal optical depth <0.06 at 825 cm (super -1) ) ice clouds and hazes were widespread, showing a distinct latitudinal gradient. With the onset of a regional dust storm at L (sub s) = 224 degrees , ice clouds vanished in the southern hemisphere, to reappear gradually after the decay of the storm. The zonally averaged cloud opacities show little difference between the beginning and end of the first Martian year. A broad low-latitude cloud belt with considerable longitudinal structure was present in early northern summer. Apparently characteristic of the northern summer season, it vanished between L (sub s) = 140 degrees and 150 degrees . The latitudinal extent of this feature is apparently controlled by the ascending branch of the Hadley circulation. The most opaque clouds (optical depth approximately 0.6) were found above the summits of major volcanic features; these showed spatial structure possibly associated with wave activity. Variety among low-lying late morning clouds suggests localized differences in circulation and microclimates. Limb observations showed extensive optically thin (optical depth <0.04) stratiform clouds at altitudes up to 55 km. Considerable latitude and altitude variations were evident in ice clouds in early northern spring (L (sub s) = 25 degrees ); near 30 km, thin clouds extended from just north of the equator to approximately 45 degrees N, nearly to the north polar vortex. A water ice haze was present in the north polar night (L (sub s) = 30 degrees ) at altitudes up to 40 km. Because little dust was present this probably provided heterogeneous nucleation sites for the formation of CO (sub 2) clouds and snowfall at altitudes below approximately 20 km, where atmospheric temperatures dropped to the CO (sub 2) condensation point. The relatively invariant spectral shape of the water ice cloud feature over space and time indicates that ice particle radii are generally between 1 and 4 mu m.

To improve the initialization of soil moisture in the NASA Seasonal-to-Interannual Prediction Project (NSIPP), a one-dimensional Kalman filter has been developed to assimilate near-surface soil moisture observations into the catchment-based land surface model used by NSIPP. A set of numerical experiments was performed using an uncoupled version of the NSIPP land surface model to evaluate the assimilation procedure. In this study, "true" land surface data were generated by spinning-up the land surface model for 1987 using the International Satellite Land Surface Climatology Project (ISLSCP) forcing data sets. A degraded simulation was made for 1987 by setting the initial soil moisture prognostic variables to arbitrarily wet values uniformly throughout North America. The final simulation run assimilated the synthetically generated near-surface soil moisture "observations" from the true simulation into the degraded simulation once every 3 days. This study has illustrated that by assimilating near-surface soil moisture observations, as would be available from a remote sensing satellite, errors in forecast soil moisture profiles as a result of poor initialization may be removed and the resulting predictions of runoff and evapotranspiration improved. After only 1 month of assimilation the root-mean-square error in the profile storage of soil moisture was reduced to 3% vol/vol, while after 12 months of assimilation, the root-mean-square error in the profile storage was as low as 1% vol/vol.

Such variations in the gravitational field Stokes coefficient are determined up to spherical harmonic degree and order 20 and compared with satellite laser ranging (SLR) data from LAGEOSI and LAGEOS II. For most Stokes coefficients except the lowest-degree ones, this investigation indicates that the application of sea level adjustment to reduce the effects of the model's lack of mass conservation due to the Boussinesq approximation has a negligible effect on timescales less than a few years. Predicted gravitational changes show strong seasonal variability and account for a portion of the variations estimated from SLR. We conclude that, in addition to the atmosphere, the oceans are an important contributor to the temporal variations in the Earth's gravitational field. The Stokes coefficients are useful in examining oceanic mass transport between hemispheres and ocean basins. The estimated oceanic power spectrum has a spectral shape similar to the atmosphere and is well above the noise level of planned satellite missions like the Gravity Recovery and Climate Experiment (GRACE).

AN - 72229048; 11678153 AB - A very extensive study of the radiation field at aircraft altitudes has been carried out over the last few years. These investigations formed part of a European wide collaboration involving several laboratories with extensive experience in cosmic ray research and/or dosimetry. Among the main topics investigated were the charge spectra, LET spectra, anisotropy and dose values. The measurements were performed on subsonic and supersonic flights covering a wide range of altitudes and latitudes. Several active and passive instruments were employed in these studies and some results obtained with nuclear track detectors are described here. Comparisons are made with the results of other experiments and theoretical estimates using computer codes. c2001 Published by Elsevier Science Ltd.

The energies of cosmic ray nuclei at the stack surfaces can be determined by reconstructing the trajectories of ions stopping inside the detector material and by measuring their ranges.

AN - 72227461; 11678155 AB - For observation of low energy cosmic ray particles we used CN-Kodak nuclear track detectors on Cosmos satellites. In solar quiet periods during solar minima conditions the detectors registered anomalous cosmic rays (ACRs). The ACRs are characterized by flux enhancements of several elements and it is known that the carbon enhancement is small compared with that of oxygen. In all of our quiet-time exposures the relation between carbon and oxygen was extremely small (C/O ~ 0.03). But in two quiet-time periods of 14.03.96-11.06.96 and of 15.12.97-14.04.98 we have identified many tracks as carbon in a L-R diagram. As a result the observed C/O ratio appears to be more than 0.5, whereas other experiments show no evidence of enhanced flux of carbon during these periods. The reason for the unexpected response of CN-Kodak is discussed. c2001 Elsevier Science Ltd. All rights reserved.

A new method for the determination of effective charge states of heavy ions is based on the measurement of the number of high-energy delta-electrons which are ejected from a target by the penetrating ion. These electrons are detectable with a CCD-detector and their number can be correlated to the effective charge state of the projectile for known particle velocities. This method is even applicable to operation with single swift heavy ions within statistical bounds. c2001 Elsevier Science Ltd. All rights reserved.

AN - 71356540; 12033222 AB - NADH oxidase activities measured with excised roots of dark-grown maize (Zea mays) seedlings and with isolated plasma membrane vesicles from roots of dark-grown maize oscillated with a regular period length of 24 min and were inhibited by the synthetic auxin 2,4-dichlorophenoxyacetic [correction of dichorophenoxyacetic] acid. The activities also responded to orientation with respect to gravity and to imposed centrifugal forces. Turning the roots upside down resulted in stimulation of the activity with a lag of about 10 min. Returning the sections to the normal upright position resulted in a return to initial rates. The activity was stimulated reversibly to a maximum of about 2-fold with isolated plasma membrane vesicles, when subjected to centrifugal forces of 25 to 250 x g for 1 to 4 min duration. These findings are the first report of a gravity-responsive enzymatic activity of plant roots inhibited by auxin and potentially related to the gravity-induced growth response. c2001 Editions scientifiques et medicales Elsevier SAS.

AN - 71294590; 11855415 AB - FLUKA is an integrated particle transport code that has enhanced multigroup low-energy neutron transport capability similar to the well-known MORSE transport code. Gammas are produced in groups but many important individual lines are specifically included, and subsequently transported by the main FLUKA routines which use a modified version of EGS4 for electromagnetic (EM) transport. Recoil protons are also transported by the primary FLUKA transport simulation. The neutron cross-section libraries employed within FLUKA were supplied by Giancarlo Panini (ENEA, Italy) based upon the most recent data from JEF-1, JEF-2.2, ENDF/B-VI, JENDL-3, etc. More than 60 different materials are included in the FLUKA databases with temperature ranges including down to cryogenic temperatures. This code has been used extensively to model the neutron environments near high-energy physics experiment shielding. A simulation of the Space Shuttle based upon a spherical aluminum equivalent shielding distribution has been performed with reasonable results. There are good prospects for extending this calculation to a more realistic 3-D geometrical representation of the Shuttle including an accurate representation of its composition, which is an essential ingredient for the improvement of the predictions. A proposed project to develop a combined analysis and simulation package based upon FLUKA and the analysis infrastructure provided by the ROOT software is under active consideration. The code to be developed for this project will be of direct application to the problem of simulating the neutron environment in space, including the albedo effects. c2001 Elsevier Science Ltd.

AN - 71287492; 11852943 AB - The radiation environment inside a shielded volume is highly complex, consisting of both charged and neutral particles. Since the inception of human space flights, the charged particle component has received virtually all of the attention. There is however, a significant production of secondary neutrons, particularly from the aluminum structure in low earth orbiting spacecrafts. The interactions of galactic cosmic rays (GCR), and solar energetic particles with the earth's atmosphere produce a non-isotropic distribution of albedo neutrons. Inside any reasonable habitable module, the average radiation quality factor of neutrons is about 4-5 times larger than the corresponding average quality factor of charged particles. The measurement of neutrons and their energy spectra is a difficult problem due the intense sources of charged particles. This paper reviews the results of Shuttle flight experiments (made during both solar maximum and solar minimum) to measure the contribution of neutrons to the dose equivalent, as well as theoretical calculations to estimate the appropriate range of neutron energies that contribute most to the dose equivalent.

AN - 71285612; 11855412 AB - A passive neutron dosemeter with thermoluminescence and etched-track detectors was used in the space station MIR in 1995 and 1997 and during some shuttle flights to MIR. High neutron doses of about 200 microSv d-1 were measured with track detectors, while the contribution of protons to the track density was estimated to be small. An active personal dosemeter based on silicon diodes providing a direct readout, improved sensitivity and spectrometric properties is proposed for additional monitoring. Firstly, measurements with a prototype were performed in the stray radiation fields of the CERN-EU Reference Radiation Facility. When mounted on a phantom at different positions, both the passive and the active dosemeter provide the directional distribution of neutrons via an unfolding procedure. This can be helpful for a better understanding of the complex radiation field in space and for comparisons with calculations. c2001 Elsevier Science Ltd. All rights reserved.

AN - 71284785; 11852942 AB - As part of a study funded by NASA MSFC to assess thecontribution of secondary particles in producing radiation damage to optoelectronics devices located on the International Space Station (IS), Monte Carlo calculations have been made to predict secondary spectra vs. shielding inside ISS modules and in electronics boxes attached on the truss (Armstrong and Colborn, 1998). The calculations take into account secondary neutron, proton, and charged pion production from the ambient galactic cosmic-ray (GCR) proton, trapped proton, and neutron albedo environments. Comparisons of the predicted neutron spectra with measurments made on the Mir space station and other spacecraft have also been made (Armstrong and Colborn, 1998). In this paper, some initial results from folding the predicted neutron spectrum inside ISS modules from Armstrong and Colborn (1998) with several types of radiation effects response functions related to electronics damage and astronaut-dose are given. These results provide an estimate of the practical importance of neutrons compared to protons in assessing radiation effects for the ISS. Also, the important neutron energy ranges for producing these effects have been estimated, which provides guidance for onboard neutron measurement requirements.

AN - 71282913; 11855414 AB - We have developed a real-time, Bonner Ball-type (neutron energy range is from thermal to 15 MeV) neutron spectral measurement system (Bonner Ball Neutron Detector (BBND)) for use on board the International Space Station (ISS). From measurements taken inside STS-89 (S/MM-8), we successfully distinguished neutrons from protons and other particles in a mixed radiation field; a task hitherto considered difficult. Although the experimental period was short, only 3.5 days (January 24-27, 1998), we were able to obtain energy spectral data and the Earth's neutron dose-equivalent map for the ISS orbital conditions (altitude 400 km, orbit inclination angle 51.6 degrees). A method for calculating the neutron energy spectrum and compensating for the particle interaction with the sensors is also described in detail. c2001 Elsevier Science Ltd. All rights reserved.

The energy dependence of response of the etched track detectors used to determine the neutron component has been characterized, partly, up to a neutron energy of 180 MeV. The neutron detectors are routinely calibrated in the CERN/EC Reference Field. The 15% determination level for total dose equivalent is 100 microSv.

Thermal/resonance neutron detectors exploiting the 6Li(n,T) alpha reaction were used to measure neutrons of energies 1 MeV ranged from 4.5 microSv/d on the low altitude STS-3 mission to 172 microSv/d on the ~6 year LDEF mission. Thermal neutrons (1 MeV and, on LDEF, neutrons >1 MeV are responsible for over 98% of the total neutron dose equivalent. Estimates of the neutron contribution to the total dose equivalent are somewhat lower than model estimates, ranging from 5.7% at a location under low shielding on LDEF to 18.4% on the highly inclined (82.3 degrees) Biocosmos-2044 mission. c2001 Elsevier Science Ltd.

AN - 71281068; 11855411 AB - Significant advances have been made in recent years to improve measurement technology and performance of phosphor materials in the fields of optically stimulated luminescence (OSL) dosimetry. Pulsed and continuous wave OSL studies recently carried out on alpha-Al2O3:C have shown that the material seems to be the most promising for routine application of OSL for dosimetric purposes. The main objective of the study is to propose a new personal dosimetry system using alpha-Al2O3:C by taking advantage of its optical properties and energy dependencies. In the process of the study, a new dose assessment algorithm was developed using artificial neural networks in hopes of achieving a higher degree of accuracy and precision in personal OSL dosimetry system. The original hypothesis of this work is that the spectral information of X- and gamma-ray fields may be obtained by the analysis of the response of a multi-element system. In this study, a feedforward neural network using the error back-propagation method with Bayesian optimization was applied for the response unfolding procedure. The validation of the proposed algorithm was investigated by unfolding the 10 measured responses of alpha-Al2O3:C for arbitrarily mixed photon fields which range from 20 to 662 keV. c2001 Elsevier Science Ltd.

The sensor consists of scintillation fibers (FIB) and will be on board the exposed facility of the Japanese Experimental module (Kibo) of the International Space Station (ISS). The sensor is one of the instruments which measures the particle and plasma environment around the ISS. The sensor will be used by the cosmonauts who work on the ISS, to help them avoid a strong particle radiation which may arrive soon. We believe that such an alert is necessary for the cosmonauts to prevent unnecessary radiation from the sun. Furthermore, the sensor will be very useful in understanding the particle acceleration mechanism at the solar surface. The design of the Engineering Model (EM) was finished and its properties were investigated. This report discusses these results. c2001 Elsevier Science Ltd. All rights reserved.

Four measurement techniques were used during the experiments. The shape of spectra and their absolute values are in good agreement. According to those experiments, an equivalent neutron dose depends upon effective shielding thickness and spacecraft mass. The neutron dose mentioned is comparable with that of ionizing radiation.

AN - 71278567; 11855409 AB - Like all other radiation monitors currently used in the space program, the bubble detector (which has flown on several missions) was adapted from a technology that was developed for terrestrial radiation. Bubble detectors are the most recent technology for applications in personal neutron dosimetry. They are now regarded as a mature technology and are used in many countries as a neutron dosimeter of record with approval from the respective regulatory authorities. Extensive type testing and QA of bubble detectors has been done by numerous groups, many of these to show that bubble detectors meet national radiation protection requirements prior to their acceptance as a dosimeter of record. In fact, it has been stated "Only bubble detectors achieve a sufficiently low detection threshold (to meet ICRP-60 recommendations)..." (Portal and Dietze, 1992).

AN - 71269533; 11865864 AB - Spacecraft and space habitats supporting human exploration contain a diverse population of microorganisms. Microorganisms may threaten human habitation in many ways that directly or indirectly impact the health, safety, or performance of astronauts. The ability to produce and maintain spacecraft and space stations with environments suitable for human habitation has been established over 40 years of human space flight. An extensive database of environmental microbiological parameters has been provided for short-term (< 20 days) space flight by more than 100 missions aboard the Space Shuttle. The NASA Mir Program provided similar data for long-duration missions. Interestingly, the major bacterial and fungal species found in the Space Shuttle are similar to those encountered in the nearly 15-year-old Mir. Lessons learned from both the US and Russian space programs have been incorporated into the habitability plan for the International Space Station. The focus is on preventive measures developed for spacecraft, cargo, and crews. On-orbit regular housekeeping practices complete with visual inspections are essential, along with microbiological monitoring. Risks associated with extended stays on the Moon or a Mars exploration mission will be much greater than previous experiences because of additional unknown variables. The current knowledge base is insufficient for exploration missions, and research is essential to understand the effects of space flight on biological functions and population dynamics of microorganisms in spacecraft. Equally important is a better understanding of the immune response and of human-microorganism-environment interactions during long-term space habitation.

AN - 71266203; 11855417 AB - The development of transport models for radiation shielding design and evaluation has provided a series of deterministic computer codes that describe galactic cosmic radiation (GCR), solar particle events, and experimental beams at particle accelerators. These codes continue to be modified to accommodate new theory and improvements to the particle interaction database (Cucinotta et al., 1994, NASA Technical Paper 3472, US Government Printing Office, Washington DC). The solution employed by the heavy-ion transport code HZETRN was derived with the assumption that nuclear fragments are emitted with the same velocity as the incident ion through velocity conserving nuclear interactions. This paper presents a version of the HZETRN transport code that provides a more realistic distribution of the energy of protons and neutrons emitted from GCR interactions in shields. This study shows that the expected GCR dose equivalent is lower than previously calculated for water shields that are less than 110 g cm-2 thick. Calculations of neutron energy spectra in low Earth orbit indicate substantial contributions from relativistic neutrons. c2001 Elsevier Science Ltd. All rights reseved.

AN - 71264892; 11855416 AB - Detector packages consisting of thermoluminescence detectors (TLD), nuclear emulsions and plastic track detectors were exposed at identical positions inside MIR space station and on shuttle flights inside Spacelab and Spacehab during different phases of the solar cycle. The objectives of the investigations are to provide data on charge and energy spectra of heavy ions, and the contribution of events with low-energy deposit (protons, electrons, gamma, etc.) to the dose, as well as the contribution of secondaries, such as nuclear disintegration stars and neutrons. For neutron dosimetry 6LiF (TLD600) and 7LiF (TLD700) chips were used both of which have almost the same response to gamma rays but different response to neutrons. Neutrons in space are produced mainly in evaporation and knock-on processes with energies mainly of 1-10 MeV and up to several 100 MeV, respectively. The energy spectrum undergoes continuous changes toward greater depth in the attenuating material until an equilibrium is reached. In equilibrium, the spectrum is a wide continuum extending down to thermal energies to which the 6LiF is sensitive. Based on the difference of absorbed doses in the 6LiF and 7LiF chips, thermal neutron fluxes from 1 to 2.3 cm-2 s-1 are calculated using the assumption that the maximum induced dose in TLD600 for 1 neutron cm-2 is 1.6 x 10(-10) Gy (Horowitz and Freeman, Nucl. Instr. and Meth. 157 (1978) 393). It is assumed that the flux of high-energy neutrons is at least of that quantity. Tissue doses were calculated taking as a mean ambient absorbed dose per neutron 6 x10(-12) Gy cm2 (for a10 MeV neutron). The neutron equivalent doses for the above-mentioned fluxes are 52 micro Gy d-1 and 120 micro Gy d-1. In recent experiments, a personal neutron dosimeter was integrated into the dosimeter packages. First results of this dosimeter which is based on nuclear track detectors with converter foils are reported. For future measurements, a scintillator counter with anticoincidence logic is under development. c2001 Elsevier Science Ltd. All rights reserved.

AN - 71264131; 11855420 AB - In estimating the crew exposures during an extra vehicular activity (EVA), the contribution of reentrant electrons has always been neglected. Although the flux of these electrons is small compared to the flux of trapped electrons, their energy spectrum extends to several GeV compared to about 7 MeV for trapped electrons. This is also true of splash electrons. Using the measured reentrant electron energy spectra, it is shown that the dose contribution of these electrons to the blood forming organs (BFO) is more that 10 times greater than that from the trapped electrons. The calculations also show that the dose-depth response is a very slowly changing function of depth, and thus adding reasonable amounts of additional shielding would not significantly lower the dose to BFO.

AN - 71263431; 11855418 AB - The interaction of high-energy space radiation with spacecraft materials generates a host of secondary particles, some, such as neutrons, are more biologically damaging and penetrating than the original primary particles. Before committing astronauts to long term exposure in such high radiation environments, a quantitative understanding of the exposure and estimates of the associated risks are required. Energetic neutrons are traditionally difficult to measure due to their neutral charge. Measurement methods have been limited by mass and weight requirements in space to nuclear emulsion, activation foils, a limited number of Bonner spheres, and TEPCs. Such measurements have had limited success in quantifying the neutron component relative to the charged components. We will show that a combination of computational models and experimental measurements can be used as a quantitative tool to evaluate the radiation environment within the Shuttle, including neutrons. Comparisons with space measurements are made with special emphasis on neutron sensitive and insensitive devices. c2001 Elsevier Science Ltd. All rights reserved.

AN - 71262944; 11855419 AB - A very high-momentum resolution particle spectrometer called the Alpha Magnetic Spectrometer (AMS) was flown in the payload bay of the Space Shuttle in a 51.65 degrees x 380-km orbit during the last solar minimum. This spectrometer has provided the first high statistics data set for galactic cosmic radiation protons, and helium, as well as limited spectral data on carbon and oxygen nuclei in the International Space Station orbit. First measurements of the albedo protons at this inclination were also made. Because of the high-momentum resolution and high statistics, the data can be separated as a function of magnetic latitude. A related investigation, the balloon borne experiment with a superconducting solenoid spectrometer (BESS), has been flown from Lynn Lake, Canada and has also provided excellent high-resolution data on protons and helium. These two data sets have been used here to study the validity of two galactic cosmic ray models and the geomagnetic transmission function developed from the 1990 geomagnetic reference field model. The predictions of both the CREME96 and NASA/JSC models are in good agreement with the AMS data. The shape of the AMS measured albedo proton spectrum, up to 2 GeV, is in excellent agreement with the previous balloon and satellite observations. A new LIS spectrum was developed that is consistent with both previous and new BESS 3He observations. Because the astronaut radiation exposures onboard ISS will be highest around the time of the solar minimum, these AMS measurements and these models provide important benchmarks for future radiation studies. AMS-02 slated for launch in September 2003, will provide even better momentum resolution and higher statistics data. Published by Elsevier Science Ltd.

AN - 70976020; 11434102 AB - The formation of pyruvaldehyde from triose sugars was catalyzed by poly-l-lysine contained in a small dialyzer with a 100 molecular weight cut off (100 MWCO) suspended in a much larger triose substrate reservoir at pH 5.5 and 40 degrees C. The polylysine confined in the dialyzer functioned as a catalytic flow reactor that constantly brought in triose from the substrate reservoir by diffusion to offset the drop in triose concentration within the reactor caused by its conversion to pyruvaldehyde. The catalytic polylysine solution (400 mM, 0.35 mL) within the dialyzer generated pyruvaldehyde with a synthetic intensity (rate/volume) that was 3400 times greater than that of the triose substrate solution (12 mM, 120 mL) outside the dialyzer. Under the given conditions the final yield of pyruvaldehyde was greater than twice the weight of the polylysine catalyst. During the reaction the polylysine catalyst was poisoned presumably by reaction of its amino groups with aldehyde reactants and products. Similar results were obtained using a dialyzer with a 500 MWCO. The dialyzer method of catalyst containment was selected because it provides a simple and easily manipulated experimental system for studying the dynamics and evolutionary development of confined autocatalytic processes related to the origin of life under anaerobic conditions.

AN - 70942736; 11401157 AB - Recent years have witnessed significant progress on the miniaturization of mass spectrometers for a variety of field applications. This article describes the development and application of mass spectrometry (MS) instrumentation to support of goals of the U.S. space program. Its main focus is on the two most common space-related applications of MS: studying the composition of planetary atmospheres and monitoring air quality on manned space missions. Both sets of applications present special requirements in terms of analytical performance (sensitivity, selectivity, speed, etc.), logistical considerations (space, weight, and power requirements), and deployment in perhaps the harshest of all possible environments (space). The MS instruments deployed on the Pioneer Venus and Mars Viking Lander missions are reviewed for the purposes of illustrating the unique features of the sample introduction systems, mass analyzers, and vacuum systems, and for presenting their specifications which are impressive even by today's standards. The various approaches for monitoring volatile organic compounds (VOCs) in cabin atmospheres are also reviewed. In the past, ground-based GC/MS instruments have been used to identify and quantify VOCs in archival samples collected during the Mercury, Apollo, Skylab, Space Shuttle, and Mir missions. Some of the data from the more recent missions are provided to illustrate the composition data obtained and to underscore the need for instrumentation to perform such monitoring in situ. Lastly, the development of two emerging technologies, Direct Sampling Ion Trap Mass Spectrometry (DSITMS) and GC/Ion Mobility Spectrometry (GC/IMS), will be discussed to illustrate their potential utility for future missions. c 2001 American Society for Mass Spectrometry.

AN - 70908973; 11396557 AB - To study hormonal factors that may account for the dissociation between beverage-induced plasma sodium p[Na+] and osmotic p[Osm] concentrations that appear to refute the high theoretical correlation between p[Na+] and p[Osm]. Ten men (24 +/- SD 3 yr of age) sat reclining (head up) for 12 h in a chamber (21-23 degrees C dry bulb, 25-33% relative humidity) at 2800 m (9184 ft, 539 mm Hg) altitude (ALT), and at 321 m (1053 ft, 732 mm Hg) on the ground (GND). During 1000-1030 hours they consumed 3 fluids (12 ml x kg(-1),X = 948 ml x d(-1)) with large differences in sodium and osmotic contents: AstroAde (AA) with 185 mEq x L(-1) Na+ and 283 mOsm x kg(-1), Performance 1 (Shaklee) (P1) with 22 mEq x L(-1) Na+ and 365 mOsm kg(-1), or H2O at ALT; and only H2O on the GND. After drinking: plasma volume (PV) increased at 1200 hours by 8.3% (p < 0.05) with AA but was not significantly (NS) changed in the other sessions (Xdelta = +0.9%, range -0.9 to 2.8%); p[Na+] and p[Osm] were unchanged. Urinary rates and free-water clearances were attenuated with AA and P1 vs. those with H2O. Correlations between and among p[Na+] and p[Osm] suggest that the pNa+ ion is more tightly controlled than pOsm; and that there was no clear hormonal response that could account for this dissociation from theoretical considerations. There is significant dissociation between plasma sodium and osmotic concentrations after fluid intake. Induction and maintenance of hypervolemia requires increased (near isotonic) drink Na+ osmols rather than increased non-ionic osmols.

Diameters of the megaspherulites range from 0.3 to over 3.66 m, including an alteration layer. The megaspherulites are compound spherulites. They are holocrystalline, very fine-to fine-grained, composed of sanidine and quartz, and surrounded by a thin sanidine-quartz rind, and an alteration layer containing mordenite and 15 Aa montmorillonite. Megaspherulite crystallization began soon after the vitrophyre was emplaced as the result of sparse heterogeneous nucleation, under highly nonequilibrium conditions. Spherulite growth proceeded in a diffusion-controlled manner under lowered viscosity as a result of a high water content (5 to 7 wt%), which also contributed to sparse nucleation. When nucleation did occur, it was at a large Delta T (245-350 degrees C) on near critical-sized nuclei. Once the spherulites began to grow, continued nucleation was on existing growth cones and new, independent spherulites did not form. Sanidine crystals grew with a fibrous habit, which is favored by a large Delta T, restricting fibril lengths and diameters between 10-30 and 3-7 mu m, respectively. During crystallization, these growth cones impinged upon each other, resulting in fibril cone-free areas. These cone-free (interconal) areas consist of coarser, fine-grained phases, dominated by quartz, which crystallized from the melt as it accumulated between the crystallizing sanidine fibrils of the cones. The anhydrous nature of the sanidine and quartz suggests that their crystallization concentrated a water-rich residual fluid, enriched in Ca, Mg, and Fe, and depleted in Si, K, and Na, at the megaspherulite-vitrophyre interface. This fluid phase enclosed the megaspherulites resulting in the hydrothermal alteration of the vitrophyre, forming a hydrothermal alteration layer, as indicated by the presence of the minerals mordenite and montmorillonite.

Partition coefficients for Ni and Co between liquid Fe-Ni-S-alloy and liquid silicate (D (sub Ni) (super LA/LS) and D (sub Co) (super LA/LS) ) were determined over a pressure range between 2 and 25 GPa and a temperature range between 2100 and 2623 K. Multi-variable linear regression analysis was performed on the measured D (sub Ni) (super LA/LS) and D (sub Co) (super LA/LS) , using a formula that is partially based on thermodynamics and partially empirical relationships. The results from the experiments with non-graphite capsules revealed that the effects of oxygen fugacity are roughly consistent with Ni and Co being divalent ions in liquid silicate. Within the experimental pressure and temperature ranges, both Ni and Co become less siderophile with increasing pressure and temperature. The effect of pressure is more pronounced for Ni while the effect of temperature is more pronounced for Co. Furthermore, both effects become smaller at higher pressures and higher temperatures. Nickel and Co are less soluble in liquid silicate with higher degree of polymerization. The presence of S in liquid Fe-alloy enhances the siderophile behavior of Ni and Co. However, for a given relative proportion of Fe, Ni and Co in the Fe-alloy, D (sub Ni) (super LA/LS) and D (sub Co) (super LA/LS) are larger for the Fe-alloy with a smaller S content. Applying the observed effects of pressure, temperature, oxygen fugacity and composition on D (sub Ni) (super LA/LS) and D (sub Co) (super LA/LS) , we found that the observed partitioning of Ni and Co between core and mantle (D (sub Ni) (super core/mantle) and D (sub Co) (super core/mantle) ) can be matched at high pressures and high temperatures. The pressure-temperature range corresponds to that in the current midmantle (about 1200-1450 km in depth). Therefore, the observed high abundances and near-chondritic ratio of Ni and Co in the Earth's upper mantle can be explained by chemical equilibrium between liquid Fe-Ni-S-alloy and liquid silicate in a deep magma ocean.

There are spatial and temporal variations in the uplift rate since the 1994 earthquake that depend on the location of the tide gauge relative to the coseismic rupture features. At Seward, on the eastern side of the Kenai Peninsula, we find slow uplift that is consistent with elastic strain accumulation at the locked North American-Pacific Plate boundary. Conversely, at Seldovia and Nikiski, on the western side of the Kenai Peninsula, we find persistent rapid uplift of approximately 10 mm yr (super -1) that may be longterm transient response to the earthquake but that cannot be sustained over the entire several hundred year recurrence interval for a great earthquake. Farther to the southwest, at Kodiak, the rate of uplift is several millimeters per year but has slowed significantly over the past three and a half decades. To the east of the Kenai Peninsula we find subsidence at Cordova and an uncertain behavior at Valdez. At Cordova, and to a lesser extent Valdez, there is a mathematically significant time dependence, although the evidence for the time dependence is less compelling than at Kodiak. At Anchorage, there is little evidence of vertical motion since the earthquake.

Deforestation estimates based on surveys or sampling have large errors, and high-resolution, wall-to-wall mapping of tropical forests is necessary to assess the impacts of fragmentation. Landsat satellite images from the mid-1980s and early 1990s were thus used to map closed-canopy tropical forest extent and anthropogenic deforestation in an approximately 700000 km super(2) area of Amazonian Bolivia with precipitation >1000 mm yr super(-1). Total potential forest cover extent, including tropical deciduous forest, was 448 700 km super(2), while the area of natural non-forest formations was 245 100 km super(2). The area deforested was 15 500 km super(2) in the mid-1980s and 24 700 km super(2) by the early 1990s. The rate of tropical deforestation in the forest zone of Bolivia with >1000 mm yr super(-1) precipitation below 1500m elevation and north of 19 degree S, was 1529 km super(2) yr super(-1) from 1985-1986 to 1992-1994. Our estimates of deforestation are significantly lower than those reported by the Food and Agriculture Organization of the United Nations (FAO). We document a spatially-concentrated 'deforestation zone' in Santa Cruz where >60% of the Bolivian deforestation has occurred. These results indicate that the rate of deforestation in Bolivia has been rapid despite a relatively small human population, and, as in Brazil, clearance has concentrated in the more deciduous forests.

A continuous dataset of microwave, thermal infrared and visible satellite data has been analyzed for the first time to concurrently study in spatial detail the variability of the sea-ice cover, surface temperature, albedo and cloud statistics in the region from 1987 to 1998. Large warming anomalies during the last four years (i.e. 1995-98) are indeed apparent and spatially more extensive than previous years. The largest surface temperature anomaly occurred in 1998, but this was confined mainly to the western Arctic and the North American continent, while cooling occurred in other areas. The albedo anomalies show good coherence with the sea-ice concentration anomalies except in the central region, where periodic changes in albedo are observed, indicative of interannual changes in duration and areal extent of melt pending and snow-free ice cover. The cloud-cover anomalies are more difficult to interpret, but are shown to be well correlated with the expected warming effects of clouds on the sea-ice surface. The results from trend analyses of the data are consistent with a general warming trend and an ice-cover retreat that appear to be even larger during the last dozen years than those previously reported.

The results indicate that the current GISS model has a high sensitivity with a global annual warming of about 4 degree C for doubled CO sub(2). Enhanced warming is found at higher latitudes near sea-ice margins due to retreat of sea ice in the greenhouse experiment. Surface warming is larger in winter than in summer, in part because of the reductions in ice cover and thickness that insulate the winter atmosphere from the ocean. The annual mean reduction of sea-ice cover due to doubled CO sub(2) is about 30% for the Northern Hemisphere. The CO sub(2) experiment has a 70% reduction of sea-ice area and 55% thinning of ice in August in the Northern Hemisphere. Noticeable reduction of sea-ice cover has been found in both historical records and satellite observations. The largest reduction of simulated sea-ice extent occurs in summer, consistent with observations.

The mean latent heating profiles over six oceanic regions [Tropical Ocean and Global Atmosphere (TOGA) Coupled Ocean-Atmosphere Response Experiment (COARE) Intensive Flux Array (IFA), central Pacific, South Pacific Convergence Zone (SPCZ), east Pacific, Indian Ocean, and Atlantic Ocean] and three continental regions (South America, central Africa, and Australia) are estimated and studied. The heating profiles obtained from the results of diagnostic budget studies over a broad range of geographic locations are used to provide comparisons and indirect validation for the heating algorithm-estimated heating profiles. Three different latent heating algorithms, the Goddard Space Flight Center convective-stratiform heating (CSH), the Goddard profiling (GPROF) heating, and the hydrometeor heating (HH) algorithms are used and their results are intercompared. The horizontal distribution or patterns of latent heat release from the three different heating retrieval methods are very similar. They all can identify the areas of major convective activity [i.e., a well-defined Intertropical Convergence Zone (ITCZ) in the Pacific, a distinct SPCZ] in the global Tropics. The magnitudes of their estimated latent heating release are also in good agreement with each other and with those determined from diagnostic budget studies. However, the major difference among these three heating retrieval algorithms is the altitude of the maximum heating level. The CSH algorithm-estimated heating profiles only show one maximum heating level, and the level varies among convective activity from various geographic locations. These features are in good agreement with diagnostic budget studies.

Results show that sea ice concentration uncertainties of plus or minus 7% can affect simulated regional temperatures by more than 6 degree C, and biases in sea ice concentrations of +7% and -7% alter simulated annually averaged global surface air temperatures by -0.10 degree and +0.17 degree C, respectively, over those in the control simulation. The resulting 0.27 degree C difference in simulated annual global surface air temperatures is reduced by a third, to 0.18 degree C, when considering instead biases of +4% and -4%. More broadly, least squares fits through the temperature results of 17 simulations with ice concentration input changes ranging from increases of 50% versus the control simulation to decreases of 50% yield a yearly average global impact of 0.0107 degree C warming for every 1% ice concentration decrease, that is, 1.07 degree C warming for the full +50% to -50% range. Regionally and on a monthly average basis, the differences can be far greater, especially in the polar regions, where wintertime contrasts between the +50% and -50% cases can exceed 30 degree C. However, few statistically significant effects are found outside the polar latitudes, and temperature effects over the nonpolar oceans tend to be under 1 degree C, due in part to the specification of an unvarying annual cycle of sea surface temperatures. The plus or minus 7% and plus or minus 4% results provide bounds on the impact (on GISS GCM simulations making use of satellite data) of satellite-derived ice concentration inaccuracies, plus or minus 7% being the current estimated average accuracy of satellite retrievals and plus or minus 4% being the anticipated improved average accuracy for upcoming satellite instruments. Results show that the impact on simulated temperatures of imposed ice concentration changes is least in summer, encouragingly the same season in which the satellite accuracies are thought to be worst. Hence, the impact of satellite inaccuracies is probably less than the use of an annually averaged satellite inaccuracy would suggest.

The hydrologic modeling strategy is developed to optimize spatial representation of basin characteristics while maximizing computational efficiency. The model employs the "grouped response unit" methodology, which follows the natural drainage pattern of the area. First order streams are delineated and their surface characteristics are tested so that areas with statistically similar characteristics can be combined into larger computational zones for modeling purposes. Hydrologic response units (HRU) are identified within the modeling units and a simple three-layer water balance model, Soil and Water Assessment Tool (SWAT), is executed for each HRU. The runoff values are then convoluted using a triangular unit hydrograph and routed by Muskingum-Cunge method. The methodology is shown to produce accurate results relative to other studies, when compared to observations. The model is used to evaluate the potential error in hydrologic assessments when using GCM predictions as climatic input in a rainfall-runoff dominated environment. In such areas, the results from this study, although limited in temporal and spatial scope, appear to imply that use of GCM climate predictions in short term quantitative analyses studies in rainfall-runoff dominated environments should proceed with caution.

The direct insertion and Kalman filter assimilation schemes have been used most frequently in assimilation studies, but no comparisons of these schemes have been made. This study investigates which of these approaches is able to retrieve the soil moisture and temperature profiles the fastest, over what depth soil moisture observations are required, and the effect of update interval on profile retrieval. These questions are addressed by a desktop study using synthetic data. The study shows that the Kalman filter assimilation scheme is superior to the direct insertion assimilation scheme, with retrieval of the soil moisture profile being achieved in 12 h as compared to 8 days or more, depending on observation depth, for hourly observations. It was also found that profile retrieval could not be realised for direct insertion of the surface node alone, and that observation depth does not have a significant effect on profile retrieval time for the Kalman filter. The observation interval was found to be unimportant for profile retrieval with the Kalman filter when the forcing data is accurate, whilst for direct insertion the continuous Dirichlet boundary condition was required for an increasingly longer period of time. It was also found that the Kalman filter assimilation scheme was less susceptible to unstable updates if volumetric soil moisture was modelled as the dependent state rather than matric head, because the volumetric soil moisture state is more linear in the forecasting model.

Each transect included only one of the following habitats: (1) offshore of a breeding island or roosting/loafing area, (2) reef or shoal (> 3 km offshore and average depth 3 km offshore and average depth > 10 m), or (4) offshore of an island shoreline that had evidence of "development" by humans. Foraging cormorants were recorded most often offshore of breeding islands and roosting/loafing areas and least often on open water. There was no difference between the number of cormorants recorded offshore of "developed" shorelines and on reefs and shoals. The number of boats recorded within 500 m of the transects during each observation period did not influence the number of foraging cormorants observed. Statistical analyses suggest that depth and shoreline type were more important than distance from shore or from nearest breeding colony for predicting the number of foraging cormorants. These results support previous studies in which the impact of P. auritus on the fishery of western Lake Erie is localized with respect to habitat.

Airborne laser altimeter waveform data was acquired using the Scanning Lidar Imager of Canopies by Echo Recovery (SLICER) for a successional sequence of four, closed-canopy, deciduous forest stands in eastern Maryland. The four stands were selected so as to include a range of canopy structures of importance to forest ecosystem function, including variation in the height and roughness of the outermost canopy surface and the vertical organization of canopy stories and gaps. The character of the SLICER backscatter signal is described and a method is developed that accounts for occlusion of the laser energy by canopy surfaces, transforming the backscatter signal to a canopy height profile (CHP) that quantitatively represents the relative vertical distribution of canopy surface area. The transformation applies increased weighting to the backscatter amplitude as a function of closure through the canopy and assumes a horizontally random distribution of the canopy components. SLICER CHPs, averaged over areas of overlap where altimeter ground tracks intersect, are shown to be highly reproducible. CHP transects across the four stands reveal spatial variations in vegetation, at the scale of the individual 10-m-diameter laser footprints, within and between stands. Averaged SLICER CHPs are compared to analogous height profile results derived from ground-based sightings to plant intercepts measured on plots within the four stands. The plots were located on the segments of the altimeter ground tracks from which averaged SLICER CHPs were derived, and the ground observations were acquired within 2 weeks of the SLICER data acquisition to minimize temporal change. The differences in canopy structure between the four stands is similarly described by the SLICER and ground-based CHP results. However, a chi-square test of similarity documents differences that are statistically significant. The differences are discussed in terms of measurement properties that define the smoothness of the resulting CHPs and canopy properties that may vertically bias the CHP representations of canopy structure. The statistical differences are most likely due to the more noisy character of the ground-based CHPs, especially high in the canopy where ground-based sightings are rare resulting in an underestimate of canopy surface area and height, and to departures from assumptions of canopy uniformity, particularly regarding lack of clumping and vertically constant canopy reflectance, which bias the CHPs. The results demonstrate that the SLICER observations reliably provide a measure of canopy structure that reveals ecologically interesting structural variations such as those characterizing a successional sequence of closed-canopy, broadleaf forest stands.

AIR 2001 Annual Forum Paper. AN - 62255589; ED456784 AB - Data from the High School and Beyond Study were used to study the pathways taken by members of the High School Class of 1982 to a college degree. The class of 1982 followed nine different pathways to a 4-year degree, paths formed by a combination of academic resources secured in high school and the first type of postsecondary institution attended. The pathway most likely to lead to 4-year degree is one defined by acquiring high academic resources in high school and entering a 4-year institution on high school completion. Those who followed this path had a 77% chance to graduate within 11 years. Most students of high socioeconomic status followed this pathway, and they with a 81% graduation rate. Most students of the lowest socioeconomic status studied journeyed on a pathway defined by moderate academic resources and first enrollment in a 2-year institution. Only 3.3% of these students earned a 4-year degree. Forty percent of the class of 1982 first entered a community college, and 29% of them transferred to a 4-year institution within 11 years. By 1993, 35% of the members of the High School Class of 1982 had obtained at least a bachelor's degree. Degree completion was affected most by socioeconomic status, academic resources, degree aspirations, enrollment patterns, taking college courses in mathematics and sciences, financial aid, and having children while attending college.

All lodgepole pines in three replicate plots were defoliated 50%, while Engelmann spruce were left untreated. This was done to determine how defoliation of one conifer species would affect EM mutualisms of both treated and neighboring, untreated conifers. The results indicated no significant effect on either EM colonization (142.0 EM tips/core in control plots and 142.4 in treatment plots) or species richness (5.0 species/core in controls and 4.5 in treatments). However, the relative abundance of EM of the two tree species shifted from a ratio of approximately 6:1 without treatment (lodgepole EM:spruce EM), to a near 1:1 ratio post-treatment. This shift may be responsible for maintaining total EM colonization and species richness following defoliation. In addition, EM species composition changed significantly post-defoliation; the system dominant, an Inocybe species, was rare in defoliation plots, while Agaricoid and Suilloid species that were rare in controls were dominant in treatments. Furthermore, species of EM fungi associating with both lodgepole pine and Engelmann spruce were affected, which indicates that changing the photosynthetic capacity of one species can affect mycorrhizal associations of neighboring non-defoliated trees.

We investigated this hypothesis using a regional ecosystem model for net primary production (NPP) and soil biogeochemical cycling. Seasonal and interannual controls on net ecosystem production (NEP) were studied with integration of high-resolution (8-km) multiyear satellite data to characterize Amazon land surface properties over time. Background analysis of temporal and spatial relationships between regional rainfall patterns and satellite observations (for vegetation land cover, fire counts, and smoke aerosol effects) reveals several notable patterns in the model driver data. Autocorrelation analysis for monthly vegetation "greenness" index (normalized difference vegetation index, NDVI) from the advanced very high resolution radiometer (AVHRR) and monthly rainfall indicates a significant lag time correlation of up to 12 months. At lag times approaching 36 months, autocorrelation function (ACF) values did not exceed the 95% confidence interval at locations west of about 47 degree W, which is near the transition zone of seasonal tropical forest and other (nonforest) vegetation types. Even at lag times of 12 months or less, the location near Manaus (approximately 60 degree W) represents the farthest western point in the Amazon region where seasonality of rainfall accounts significantly for monthly variations in forest phenology, as observed using NDVI. Comparisons of NDVI seasonal profiles in areas of the eastern Amazon widely affected by fires (as observed from satellite) suggest that our adjusted AVHRR-NDVI captures year-to-year variation in land cover greenness with minimal interference from small fires and smoke aerosols. Ecosystem model results using this newly generated combination of regional forcing data from satellite suggest that undisturbed Amazon forests can be strong net sinks for atmospheric carbon dioxide, particularly during wet (non El Nino) years. However, drought effects during El Nino years can reduce NPP in primary forests of the eastern Amazon by 10-20%, compared to long-term average estimates of regional productivity. Annual NEP for the region is predicted to range from -0.4 Pg C yr super(-1) (net CO sub(2) source) to 0.5 Pg C yr super(-1) (net CO sub(2) sink), with large interannual variability over the states of Para, Maranhao, and Amazonas. As in the case of predicted NPP, it appears that periods of relatively high solar surface irradiance combined with several months of adequate rainfall are required to sustain the forest carbon sink for positive yearly NEP estimates.

The simulation results are compared with ozone observations from three platforms: the differential absorption lidar (DIAL), the Microwave Limb Sounder (MLS), and the Polar Ozone and Aerosol Measurement (POAM II). Time series for the different data sets are consistent with each other, and diverge from model time series during December and January. The model ozone in December and January is much less sensitive to the model photochemistry than to the model vertical transport. Simulations with different initial conditions for ozone demonstrate sensivitity to the model ozone profile shape. The modeled ozone throughout December and January most closely resembles observed ozone when the vertical profiles between 12 and 20 km within the polar vortex closely match December DIAL observations. We make a quantitative estimate of the uncertainty in the vertical advection using diabatic trajectory calculations. The net transport uncertainty is significant and should be accounted for when comparing observations with model ozone. The observed and modeled ozone time series during December and January are not inconsistent when these transport uncertainties are taken into account. JF - Journal of Geophysical Research. D.

AN - 17875449; 5115699 AB - Discovery of bacteria that remain viable in a dormant state for lengthy periods is significant for understanding patterns of microbial diversity and evolution on Earth, as well as for assessing the possibility of life's interplanetary transport by impact processes. The isolation by Vreeland et al. of viable 250-million-year-old bacteria is an extraordinary claim, based on meticulous extraction from evaporite deposits of the Delaware Basin. If valid, this discovery expands dramatically the maximum proposed age for microbial survivability. Here we argue that, although the Permian age of these well-documented deposits is not in question, the fluid inclusions and the viable bacterial spores contained in them may represent much more recent features. The age of these microbes must therefore remain uncertain. JF - Nature AU - Hazen, R M AU - Roedder, E AD - Geophys. Lab. and NASA Astrobiol.

Two experiments examined the role of workload (number of airplanes that participants directed), delay (between receipt of prospective instructions & execution), & phonological rehearsal. High workload increased prospective memory errors but increasing delay from 1-3 or 5 minutes had no effect. Shadowing aurally presented text reduced prospective memory performance, presumably because it prevented verbal rehearsal of the prospective instructions. However, performance on the foreground task of directing airplanes to routine destinations was affected only by workload & not by opportunity for rehearsal. Our results suggest that ability to maintain performance on a routine foreground task while performing a secondary task - perhaps analogous to conversation - does not predict ability to retrieve a prospective intention to deviate from the routine. 5 Tables, 1 Figure, 37 References.

AN - 72332045; 11757570 AB - A tunable mid-infrared continuous-wave (cw) spectroscopic source in the 3.4-4.5 micrometers region is reported, based on difference frequency generation (DFG) in a quasi-phase-matched periodically poled RbTiOAsO4 (PPRTA) crystal. DFG power levels of 10 microW were generated at approximately 4 micrometers in a 20-mm long PPRTA crystal by mixing two cw single-frequency Ti:Al2O3 lasers operating near 713 nm and 871 nm, respectively, using a laser pump power of 300 mW. A quasi-phase-matched infrared wavelength-tuning bandwidth (FWHM) of ~ 12 cm-1 and a temperature tuning rate of 1.02 cm-1/degree C were achieved. Experimental details regarding the feasibility of trace gas detection based on absorption spectroscopy of CO2 in ambient air using this DFG radiation source are also described. JF - Applied physics.

The imprint of such an epoch might be retained in the spatial distribution of planetary material, the systematic deviations of its elemental composition from that of the Sun, chemical indicators of primordial oxidation state, and variations in oxygen and other isotopic compositions. Our method of investigation is to calculate the time-dependent, two-dimensional temperature distributions within model nebulas of prescribed dynamical evolution, and to deduce the consequences of the calculated thermal histories for coagulated solid material. The models are defined by parameters which characterize nebular initial states (mass and angular momentum), mass accretion histories, and coagulation rates and efficiencies. It is demonstrated that coagulation during the cooling of the nebula from a hot state is expected to produce systematic heterogeneities which affect the chemical and isotopic compositions of planetary material. The radial thermal gradient at the midplane results in delayed coagulation of the more volatile elements. Vertical thermal gradients isolate the most refractory material and concentrate evaporated heavy elements in the gas phase. It is concluded that these effects could be responsible for the distribution of terrestrial planetary masses, the systematic depletion patterns of the moderately volatile elements in chondritic meteorites and the Earth, the range of oxygen isotopic compositions exhibited by calcium-aluminum-rich inclusions (CAIs) and other refractory inclusions, and some geochemical evidence for a moderately enhanced oxidation state. However, nebular fractionations on a global scale are unlikely to account for the more oxidizing conditions inferred for some CAIs and chondritic silicates, which require dust enhancements greater than a few hundred. This conclusion, along with the well-established evidence from studies of chondrules and CAIs for thermal excursions of short duration, make it likely that local environments, unrelated to nebular thermal evolution, were also important.

Hydrothermal alteration is recognized in two settings: within polymict impact breccias overlying the central portion of the structure, and within localized pipes in impact-generated concentric fault systems. The intra-breccia alteration comprises three varieties of cavity and fracture filling: (a) sulfide with carbonate, (b) sulfate, and (c) carbonate. These are accompanied by subordinate celestite, barite, fluorite, quartz and marcasite. Selenite is also developed, particularly in the lower levels of the impact breccia sheet. The fault-related hydrothermal alteration occurs in 1-7 m diameter subvertical pipes that are exposed for lengths of up 20 m. The pipes are defined by a monomict quartz-carbonate breccia showing pronounced Fe-hydroxide alteration. Associated sulfides include marcasite, pyrite and chalcopyrite. We propose three distinct stages in the evolution of the hydrothermal system: (1) Early Stage (>200 degrees C), with the precipitation of quartz (vapor phase dominated); (2) Main Stage (200-100 degrees C). with the development of a two-phase (vapor plus liquid) zone, leading to calcite, celestite, barite, marcasite and fluorite precipitation; and (3) Late Stage (<100 degrees C), with selenite and fibroferrite development through liquid phase-dominated precipitation. We estimate that it took several tens of thousands of years to cool below 50 degrees C following impact. During this time, Haughton supported a 14 km diameter crater lake and subsurface water system, providing a warmer, wetter niche relative to the surrounding terrain. The results reveal how understanding the internal structure of impact craters is necessary in order to determine their plumbing and cooling systems.

The yearly attributes of the spatial distribution of the Odden from 1979 through 1998 have been quantified in terms of average concentration, standard deviation of ice concentrations, persistence, maximum extent, and anomalies in extent, and the results show vastly different formation characteristics and seasonalities during different years. The monthly average extents of the Odden are shown to have a strong negative correlation with monthly surface air temperatures recorded at Jan Mayen Island and monthly temperatures retrieved from satellite infrared data, with correlation coefficients of 0.74 and 0.89, respectively. Wind effect is also shown to be an important factor at daily and shorter timescales, directly influencing size and shape and sometimes initiating the formation of Nordbukta. The Odden was most extensive in 1979, 1982, 1986, and 1997 and most persistent in 1988, 1989, and 1997 but did not appear in 1984, 1994, and 1995, suggesting decadal periodicity for the 20 year period. With the use of the 75 year temperature record at Jan Mayen Island as a proxy for Odden size, spectral analysis also shows a periodicity of 10-12 years. A correlation study of North Atlantic Oscillation (NAO) indices with extents of the Odden, as derived from satellite data, yields a correlation coefficient of 0.4, which suggests that the interannual variability of the Odden may be influenced but not controlled by NAO. Regression analysis of the Jan Mayen surface temperature record also yields a slight warming (0.06 K decade (super -1) ) and a decrease in Odden area (-0.14 X 10 (super 4) km (super 2) decade (super -1) ) from 1979 to 1996, but during the past 75 years, there has actually been a slight cooling (-0.15 K decade (super -1) ), suggesting either that the Odden had actually been smaller in size several decades ago or that it had occurred farther north.

Several models have commonly been used to constrain these relations, but they have not been well tested on natural or simulated lava flows over a wide range of parameter space. Here, we test the accuracy and assumptions of a moderately simple analytic rectangular channel solution by comparing the behavior of well-controlled laboratory polyethylene glycol (PEG) channeled flows to the analytic solution for isothermal, steady Newtonian flow in a rectangular channel with constant dimensions. This analytic solution agrees well with laboratory measurements. Volumetric effusion rates (Q; m (super 3) s (super -1) ) calculated from the analytical model using measured PEG flows as input yield ratios of Q (sub calculated) /Q (sub pumped) of approximately 0.2 to 3.6, and flow rates calculated from a best fit surface velocity profile to measured velocities give more accurate ratios of approximately 0.8 to 1.2. We find a very weak dependence of solution accuracy on slope, attributable to flow front effects within the laboratory flows. We subsequently apply the solution to several subaerial and submarine terrestrial flows as well as extraterrestrial channeled flows over a wide range of flow parameters. Viscosity ranges and flow rates obtained using measured channel dimensions and assumed lava properties are plausible. Interestingly, the resulting extraterrestrial estimates of viscosities and flow rates tend to fall closer to known terrestrial measurements and estimates of channel flow than to previous planetary estimates. We therefore suggest that the analytic Newtonian rectangular channel flow model is a more appropriate physical model for many channeled terrestrial and planetary flows than the Newtonian infinite sheet flow and approximation to Bingham channel flow widely used previously.

We process vector Magsat data to isolate the crustal field and then invert power spectral densities of flight-local components along-track for R (sub l) following O'Brien et al. [1999]. Our model, designated LPPC, is accurate up to approximately spherical harmonic degree 45 (lambda = 900 km): this is the resolution limit of our data and suggests that global crustal anomaly maps constructed from vector Magsat data should not contain features with wavelengths less than 900 km. We find continental power spectra to be greater than oceanic ones and attribute this to the relative thicknesses of continental and oceanic crust. Copyright 2001 by the American Geophysical Union.

Because the L-band brightness temperatures associated with salinity changes are expected to be small, it was necessary to build a very sensitive and stable system. This new instrument has dual-frequency, dual polarization radiometer and radar sensors. The antenna is a high beam efficiency conical horn. The PALS instrument was installed on the NCAR C-130 aircraft and soil moisture measurements were made in support of the Southern Great Plains 1999 experiment in Oklahoma from July 8-14, 1999. Data taken before and after a rainstorm showed significant changes in the brightness temperatures, polarization ratios and radar backscatter, as a function of soil moisture. Salinity measurement missions were flown on July 17-19, 1999, southeast of Norfolk, VA, over the Gulf Stream. The measurements indicated a clear and repeatable salinity signal during these three days, which was in good agrement with the Cape Hatteras ship salinity data. Data was also taken in the open ocean and a small decrease of 0.2 K was measured in the brightness temperature, which corresponded to the salinity increase of 0.4 psu measured by the M/V Oleander vessel.

The spatial pattern consists of correlated occurrences of high (low) surface air temperature and deficit (excess) rainfall. The center of maximum amplitude in rain fluctuation is around Kansas City; that of temperature is over South Dakota. Internal consistency between temperature and precipitation variability is the salient feature of the drought pattern. A drought index is used to quantify drought severity for the period 1895-1996. The 12 severest drought months (in order) during this period are June 1933, June 1988, July 1936, August 1983, July 1934, July 1901, June 1931, August 1947, July 1930, June 1936, July 1954, and August 1936. Hydrological conditions are examined using National Centers for Environmental Prediction (NCEP) reanalysis precipitable water (PW) and monthly surface observations from Kansas City, Missouri, and Bismarck, North Dakota, near the drought centers. This analysis explains why droughts exhibit negative surface relative humidity anomalies accompanied by larger than normal monthly mean daily temperature ranges and why maximum PWs are confined to a strip of about 10 degree longitude from New Mexico and Arizona into the Dakotas and Minnesota. Dynamical conditions are examined using NCEP reanalysis sea level pressures and 500- and 200-mb geopotential heights. The analysis indicates a midtroposphere wave train with positive centers situated over the North Pacific, North America, and the North Atlantic, with negative centers in the southeastern Gulf of Alaska and Davis Strait. Above-normal sea level pressures over New Mexico, the North Atlantic, and the subtropical Pacific along with below-normal sea level pressures over the Gulf of Alaska eastward to Canada, Davis Strait, and Greenland are present during drought periods. The most prominent feature is the strong anticyclone over central North America. On a regional scale, midtropospheric westerly winds are weakened (or become easterly) south of a thermal heat low centered in South Dakota during drought episodes because of the north-south temperature reversal perturbation. The associated westward displaced Bermuda high leads to enhanced low-level warm flow into the Dakotas, thus helping to maintain the reversal in the meridional temperature gradient and the concomitant thermal wind reversal. Enhanced moisture transport from the Gulf of California into the western plains (part of the Great Basin monsoon process) results from the large-scale perturbation pressure pattern. Middle-upper level convergence maintains the water vapor strip east of the Rocky Mountains, while the Mississippi valley undergoes moisture cutoff from both this process and the westward shift in the Bermuda high. The strip of maximum PW then undergoes enhanced solar and infrared absorption that feeds back on the thermal heat low. Surface air temperatures warm while sinking motion balances middle-upper level radiative cooling around the Kansas City area. This is the dynamical coupling that leads to reduced surface relative humidities. The centers of high surface air temperature and deficit rainfall are dynamically consistent with patterns in geopotential heights, vertical velocities, and water vapor amounts.

The analysis is based on ensembles of seasonal simulations made with an atmospheric general circulation model (AGCM) forced with sea surface temperatures observed during the 1983 El Nino and 1989 La Nina events. The AGCM produces pronounced interannual differences in the magnitude of the extratropical seasonal mean noise (intraensemble JFM variability). The North Pacific, in particular, shows extensive regions in which the 1989 seasonal mean noise kinetic energy (SKE), which is dominated by a "Pacific-North American (PNA)-like" spatial structure, is more than 2 times that of the 1983 forecasts. The larger SKE in 1989 is associated with a larger-than-normal barotropic conversion of kinetic energy from the mean Pacific jet to the seasonal mean noise. The generation of SKE by submonthly transients also shows substantial interannual differences, though these are much smaller than the differences in the mean flow conversions. An analysis of the generation of monthly mean noise kinetic energy and its variability suggests that the seasonal mean noise is predominantly a statistical residue of variability resulting from dynamical processes operating on monthly and shorter timescales. A stochastically forced barotropic model (linearized about the AGCM's 1983 and 1989 seasonal and ensemble mean states) is used to further assess the role of the basic state, submonthly transients, and tropical forcing in modulating the uncertainties in the seasonal AGCM forecasts. When forced globally with spatially white noise, the linear model generates much larger variance for the 1989 basic state, consistent with the AGCM results. The extratropical variability for the 1989 basic state is dominated by a single eigenmode and is strongly coupled with forcing over the tropical western Pacific and the Indian Ocean. Linear calculations that include forcing from the AGCM variance of the tropical forcing and submonthly transients show a small impact on the variability over the PNA region as compared with that of the basic-state differences.

DESIGN AND SETTING: Occupational cohort study conducted for a mean of 5.5 y. SUBJECTS: A total of 496 (341 male and 155 female) NASA/Johnson Space Center employees who completed the 3 month education component of the employee health-related fitness program and remained involved for a minimum of 2 y. MEASUREMENTS: Body weights were measured at baseline (T1) and follow-up (T2), and habitual physical activity was obtained from the mean of multiple ratings of the 11-point (0-10) NASA Activity Scale (NAS) recorded quarterly between T1 and T2. Other measures included age, gender, VO sub(2 max) obtained from maximal treadmill testing, body mass index (BMI), and body fat percentage. RESULTS: Multiple regression demonstrated that mean NAS, T1 weight, aging and gender all influence long-term T2 weight. T1 age was significant for the men only. Independently, each increase in mean NAS significantly (P < 0.01) reduced T2 weight in men (b = -0.91 kg; 95% CI: -1.4 to -0.42 kg) and women (b = -2.14 kg; 95% CI: -2.93 to -1.35 kg). Mean NAS had a greater effect on T2 weight as T1 weight increased, and the relationship was dose-dependent. CONCLUSIONS: Habitual physical activity is a significant source of long-term weight change. The use of self-reported activity level is helpful in predicting long-term weight changes and may be used by health care professionals when counseling patients about the value of physical activity for weight control.

However, estimates of terrestrial water storage changes soon may be derived from observations of Earth's time-dependent gravity field made by NASA's Gravity Recovery and Climate Experiment (GRACE). Previous studies have evaluated that concept using modeled soil moisture and snow data. This investigation builds upon their results by relying on observations rather than modeled results, by analyzing groundwater and surface water variations as well as snow and soil water variations, and by using a longer time series. Expected uncertainty in GRACE-derived water storage changes are compared to monthly, seasonal, and annual terrestrial water storage changes estimated from observations in Illinois (145,800 km super(2)). Assuming those changes are representative of larger regions, detectability is possible given a 200,000 km super(2) or larger area. Changes in soil moisture are typically the largest component of terrestrial water storage variations, followed by changes in groundwater plus intermediate zone storage.

With regard to the white light coronagraph data we have used data from Spartan 201-05 to construct our empirical models of the electron density and magnetic field. We then use conservations laws of mass, momentum and energy to compute estimates of the flow velocity, effective temperature and effective heat flux as a function of radial distance and latitude. We will then compare our empirical model estimates with that of other theoretical models. An example, is the WKB contribution of Alfven waves to the effective temperature and effective heat flux. We have also investigated the importance of electron heat conduction in the context as past theoretical and empirical models and present a preliminary description of a semi-empirical model of electron heat conduction.

Such oxygenated species are, for example, carriers of reactive nitrogen and are easily photolysed, producing free radicals--and so influence the oxidizing capacity and the ozone-forming potential of the atmosphere--and may also contribute significantly to the organic component of aerosols. But knowledge of the distribution and sources of oxygenated organic compounds, especially in the Southern Hemisphere, is limited. Here we characterize the tropospheric composition of oxygenated organic species, using data from a recent airborne survey conducted over the tropical Pacific Ocean (30 degree N to 30 degree S). Measurements of a dozen oxygenated chemicals (carbonyls, alcohols, organic nitrates, organic pernitrates and peroxides), along with several C sub(2)-C sub(8) hydrocarbons, reveal that abundances of oxygenated species are extremely high, and collectively, oxygenated species are nearly five times more abundant than non-methane hydrocarbons in the Southern Hemisphere. Current atmospheric models are unable to correctly simulate these findings, suggesting that large, diffuse, and hitherto-unknown sources of oxygenated organic compounds must therefore exist. Although the origin of these sources is still unclear, we suggest that oxygenated species could be formed via the oxidation of hydrocarbons in the atmosphere, the photochemical degradation of organic matter in the oceans, and direct emissions from terrestrial vegetation.

AN - 77061450; 11309612 AB - Nature abounds with intricate composite architectures composed of hard and soft materials synergistically intertwined to provide both useful functionality and mechanical integrity. Recent synthetic efforts to mimic such natural designs have focused on nanocomposites, prepared mainly by slow procedures like monomer or polymer infiltration of inorganic nanostructures or sequential deposition. Here we report the self-assembly of conjugated polymer/silica nanocomposite films with hexagonal, cubic or lamellar mesoscopic order using polymerizable amphiphilic diacetylene molecules as both structure-directing agents and monomers. The self-assembly procedure is rapid and incorporates the organic monomers uniformly within a highly ordered, inorganic environment. Polymerization results in polydiacetylene/silica nanocomposites that are optically transparent and mechanically robust. Compared to ordered diacetylene-containing films prepared as Langmuir monolayers or by Langmuir-Blodgett deposition, the nanostructured inorganic host alters the diacetylene polymerization behaviour, and the resulting nanocomposite exhibits unusual chromatic changes in response to thermal, mechanical and chemical stimuli. The inorganic framework serves to protect, stabilize, and orient the polymer, and to mediate its function. The nanocomposite architecture also provides sufficient mechanical integrity to enable integration into devices and microsystems.

We focus on the projection of the induced responses onto Northern Hemisphere winter surface climate. Changes in the model's surface climate take place largely through enhancement of existing variability patterns, with greenhouse gases, polar ozone depletion, and volcanic eruptions primarily affecting the Arctic Oscillation (AO) pattern. Perturbations descend from the stratosphere to the surface in the model by altering the propagation of planetary waves coming up from the surface, in accord with observational evidence. Models lacking realistic stratospheric dynamics fail to capture these wave flux changes. The results support the conclusion that the stratosphere plays a crucial role in recent AO trends. We show that in our climate model, while ozone depletion has a significant effect, greenhouse gas forcing is the only one capable of causing the large, sustained increase in the AO observed over recent decades. This suggests that the AO trend, and a concurrent strengthening of the stratospheric vortex over the Arctic, are very likely anthropogenic in origin. JF - Journal of Geophysical Research. D.

AN - 85234308; pmid-11355385 AB - To better understand the mechanisms of human adaptation to rotating environments, we exposed 19 healthy subjects and 8 vestibular-deficient subjects ("abnormal"; four bilateral and four unilateral lesions) to an interaural centripetal acceleration of 1 g (resultant 45 degrees roll-tilt of 1.4 g) on a 0.8-m-radius centrifuge for periods of 90 min. The subjects sat upright (body z-axis parallel to centrifuge rotation axis) in the dark with head stationary, except during 4 min of every 10 min, when they performed head saccades toward visual targets switched on at 3- to 5-s intervals at random locations (within +/- 30 degrees) in the earth-horizontal plane. Eight of the normal subjects also performed the head saccade protocol in a stationary chair adjusted to a static roll-tilt angle of 45 degrees for 90 min (reproducing the change in orientation but not the magnitude of the gravitoinertial force on the centrifuge). Eye movements, including voluntary saccades directed along perceived earth- and head-referenced planes, were recorded before, during, and immediately after centrifugation. Postural center of pressure (COP) and multisegment body kinematics were also gathered before and within 10 min after centrifugation. Normal subjects overestimated roll-tilt during centrifugation and revealed errors in perception of head-vertical provided by directed saccades. Errors in this perceptual response tended to increase with time and became significant after approximately 30 min. Motion-sickness symptoms caused approximately 25% of normal subjects to limit their head movements during centrifugation and led three normal subjects to stop the test early. Immediately after centrifugation, subjects reported feeling tilted 10 degrees in the opposite direction, which was in agreement with the direction of their earth-referenced directed saccades. Postural COP, segmental body motion amplitude, and hip-sway frequency increased significantly after centrifugation. These postural effects were short-lived, however, with a recovery time of several postural test trials (minutes). There were also asymmetries in the direction of postcentrifugation COP and head tilt which depended on the subject's orientation during the centrifugation adaptation period (left ear or right ear out). The amount of total head movements during centrifugation correlated poorly or inversely with postcentrifugation postural stability, and the most unstable subject made no head movements. There was no decrease in postural stability after static tilt, although these subjects also reported a perceived tilt briefly after return to upright, and they also had COP asymmetries. Abnormal subjects underestimated roll-tilt during centrifugation, and their directed saccades revealed permanent spatial distortions. Bilateral abnormal subjects started out with poor postural control, but showed no postural decrements after centrifugation, while unilateral abnormal subjects had varying degrees of postural decrement, both in their everyday function and as a result of experiencing the centrifugation. In addition, three unilateral, abnormal subjects, who rode twice in opposite orientations, revealed a consistent orthogonal pattern of COP offsets after centrifugation. These results suggest that both orientation and magnitude of the gravitoinertial vector are used by the central nervous system for calibration of multiple orientation systems. A change in the background gravitoinertial force (otolith input) can rapidly initiate postural and perceptual adaptation in several sensorimotor systems, independent of a structured visual surround.

Eighty-one percent of those 1988 eighth graders who completed these three tasks enrolled in college by 1994. The path to college among socioeconomically disadvantaged middle high school students can best be characterized as hazardous. By 1994, just 1 out of 10 of the original class of 1988 poor eighth graders was attending a 4-year institution. Comparative analyses of lowest and highest SES students reveal substantial differences between these two groups, favoring upper-SES individuals at each of the three tasks on the path to college. These substantial SES-gaps are reduced, if not eliminated, once a number of influential school-based and family background variables are taken into account.[PUBLICATION ABSTRACT] JF - Research in Higher Education AU - Cabrera, Alberto F AU - La Nasa, Steven M Y1 - 2001/04// PY - 2001 DA - Apr 2001 SP - 119 EP - 149 CY - New York PB - Springer Science & Business Media VL - 42 IS - 2 SN - 0361-0365 KW - Education KW - Colleges & universities KW - 8306:Schools and educational services UR - http://libproxy.lib.unc.edu/login?url=http://search.proquest.com/docview/763669165?accountid=14244 L2 - http://vb3lk7eb4t.search.serialssolutions.com/?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQ%3Aeducation&rft_val_fmt=info:ofi/fmt:kev:mtx:journal&rft.genre=article&rft.jtitle=Research+in+Higher+Education&rft.atitle=On+the+Path+to+College%3A+Three+Critical+Tasks+Facing+America%27s+Disadvantaged&rft.au=Cabrera%2C+Alberto+F%3BLa+Nasa%2C+Steven+M&rft.aulast=Cabrera&rft.aufirst=Alberto&rft.date=2001-04-01&rft.volume=42&rft.issue=2&rft.spage=119&rft.isbn=&rft.btitle=&rft.title=Research+in+Higher+Education&rft.issn=03610365&rft_id=info:doi/10.1023%2FA%3A1026520002362 LA - English DB - ProQuest Central N1 - Copyright - Human Sciences Press, Inc. 2001 N1 - Last updated - 2014-07-26 DO - http://dx.doi.org/10.1023/A:1026520002362 ER - TY - JOUR T1 - Protective effects of tea polyphenols on mild hypobaric hypoxia induced pulmonary free radical metabolic disorder in mice. AN - 72415110; 11806426 AB - Objective. To observe the protective effects of natural antioxidant tea polyphenols (TP) on repeated mild hypobaric hypoxia induced pulmonary free radical metabolic disorder in mice. Method. Fourty-two male Kunming mice were randomly divided into three groups (n=14 each): normal control (A); 1500 in mild hypobaric hypoxia (B) and TP protection group (C). The exposure time in hypobaric chamber was 2 h/d, 3d/wk, 8 wk in total. Before hypoxic exposure, TP was orally given to group C at a dose of 100 mg/kg, while distilled water was given to the other two groups. After experiment, the mice were decapitated on the next day and the lung was quickly removed. The malondialdehyde (MDA) concentration, superoxide dismutase (SOD) activity and nitric oxide (NO) content were measured. In addition, Cu, Zn-SOD and inducible NO synthase (iNOS) enzymatic contents in lung were were qualitatively examined by immunohistochemical assaying. Result. Compared with the control group, pulmonary MDA concentration and NO content were significantly increased after chronic mild hypobaric hypoxic exposures (P<0.01) but the MDA formation and NO generation in TP protection group were restored to normal. Pulmonary SOD activity in group B tended to increase. Cu, Zn-SOD expression in endothelial cells of bronchioli and iNOS contents in endothelial cells of bronchioli and endothelial cells and smooth muscle cells in pulmonary interstitial vessels were significantly elevated after repeated mild hypobaric hypoxic exposure. These enzymatic abnormal expressions regained to normal after administration of TP. Conclusion.

AN - 72413223; 11808573 AB - Response of LiF thermoluminescence (TL) detector to charged particle is dependent on particles' LET. High LET can cause reduction of detector response and underestimation of radiation dose. This paper summarized the response of LiF detector to charged particles' LET, and suggested a new approach to solve the dose contribution of high LET charged particles.

It is a basaltic shergottitic rock composed of olivine megacrysts reaching 5 mm (24 vol%) set in a fine-grained groundmass of pyroxene (59 vol%) and maskelynitized plagioclase (12 vol%) with minor amounts of accessory phases (spinel, merrillite, ilmenite). Dar al Gani 476 is similar to lithology A of Elephant Moraine A79001 (EETA79001) in petrography and mineralogy, but is distinct in several aspects. Low-Ca pyroxenes in the Dar al Gani 476 groundmass are more magnesian (En (sub 76) Fs (sub 21) Wo (sub 3) -En (sub 58) Fs (sub 30) Wo (sub 12) ) than those in lithology A of EETA79001 (En (sub 73) Fs (sub 22) Wo (sub 5) -En (sub 45) Fs (sub 43) Wo (sub 12) ), rather similar to pyroxenes in lherzolitic martian meteorites (En (sub 76) Fs (sub 21) Wo (sub 3) -En (sub 63) Fs (sub 22) Wo (sub 15) ). Dar al Gani 476 olivine is less magnesian and shows a narrower compositional range (Fo (sub 76-58) ) than EETA79001 olivine (Fo (sub 81-53) ), and is also similar to olivines in lherzolitic martian meteorites (Fo (sub 74-65) ). The orthopyroxene-olivine-chromite xenolith typical in the lithology A of EETA79001 is absent in Dar al Gani 476. It seems that Dar al Gani 476 crystallized from a slightly more primitive mafic magma than lithology A of EETA79001 and several phases (olivine, pyroxene, chromite, and ilmenite) in Dar al Gani 476 may have petrogenetic similarities to those of lherzolitic martian meteorites. Olivine megacrysts in Dar al Gani 476 are in disequilibrium with the bulk composition. The presence of fractured olivine grains in which the most Mg-rich parts are in contact with the groundmass suggests that little diffusive modification of original olivine compositions occurred during cooling. This observation enabled us to estimate the cooling rates of Dar al Gani 476 and EETA79001 olivines, giving similar cooling rates of 0.03-3 degrees C/h for Dar al Gani 476 and 0.05-5 degrees C/h for EETA79001. This suggests that they were cooled near the surface (burial depth shallower than about 3 m at most), probably in lava flows during crystallization of groundmass. As is proposed for lithology A of EETA79001, it may be possible to consider that Dar al Gani 476 has an impact melt origin, a mixture of martian lherzolite and other martian rock (Queen Alexandra Range 94201, nakhlites?).

Comparison of morphology and spatial distribution of valleys on geologic surfaces with terrestrial fluvial valleys suggests that most martian valleys are probably not indicative of a rainfall origin, nor are they indicative of formation by an early global uniformly higher heat flow. In general, valleys are not uniformly distributed within geologic surface materials as are terrestrial fluvial valleys. Valleys tend to form either as isolated systems or in clusters on a geologic surface unit leaving large expanses of the unit virtually untouched by erosion. With the exception of fluvial valleys on some volcanoes, most martian valleys exhibit a sapping morphology and do not appear to have formed along with those that exhibit runoff morphology. In contrast, terrestrial sapping valleys form from and along with runoff valleys. The isolated or clustered distribution of valleys suggests localized water sources were important in drainage development. Persistent groundwater outflow driven by localized, but vigorous hydrothermal circulation associated with magmatism, volcanism, impacts, or tectonism is, however, consistent with valley morphology and distribution. Snowfall from sublimating ice-covered lakes or seas may have provided an atmospheric source of water for the formation of some valleys in regions where the surface is easily eroded and where localized geothermal/hydrothermal activity is sufficient to melt accumulated snowpacks.

The venusian valley networks are structurally controlled, as indicated by the morphological patterns of valley branches, consistency between valley and fracture orientations, and associations with the deformed terrains. The morphologies resemble those of terrestrial and martian sapping valleys. Valley networks on Venus probably formed initially from fracture systems and became enlarged by low viscosity lava sapping processes. Subsurface flow of lava may locally have been assisted by surface flows. The lavas probably moved through permeable media and fractures. Venusian valley networks have a higher degree of network integration than do lunar sinuous rilles, but they are less integrated than martian and terrestrial sapping valleys. The viscosity of valley-forming lavas must have been very low, but was not low enough to exploit the permeable media so extensively as to attain a high degree of network integration. The compositions of these lavas may have been mafic to ultramafic or mafic alkaline. Alternatively, the lavas could have had more exotic compositions, such as carbonatite and sulfur. Valley networks are often associated with corona and corona-like features, which are hypothesized to be the surface expressions of mantle plumes. A plume association could mean that the lavas came from the mantle. JF - Geomorphology AU - Komatsu, Goro AU - Gulick, Virginia C AU - Baker, Victor R A2 - Baker, Victor R.

Geomorphol. 37-1 (1993) 57], the hydrological characteristics of 71 pristine fluvial valley networks, located between 18.0 degrees N and 55.0 degrees S, were surveyed using Viking Orbiter photomosaic bases at 1:2 million scale. The surveyed networks display: (1) systems organized mainly as first-order streams, 85% of which have lengths not exceeding 1000 km with a large amount of the statistical sample having lengths between 200 and 500 km (generally shorter than the degraded valleys studied by Baker and Partridge [J. Geophys. Res. 91 (1986) 3561]), (2) drainage basins with average areas of about 5000 km (super 2) , (3) a random distribution, and (4) headwater tributary drainage densities (k (sub d) ) ranging systematically between 0.03 and 0.2 km (super -1) , which are comparable to terrestrial drainage densities in arid climates. The compositions of the surveyed pristine valley networks are comparable to the degraded fluvial systems that dissect older martian surface materials. Thus, it appears that no dramatic changes occurred in martian hydrology since the earlier period of formation of the "degraded valleys", such as described by Baker and Partridge [J. Geophys. Res. 91 (1986) 3561]. Subsurface aquifer drainage may have been a large contributor to drainage basin formation since early in Mars history.

During this traverse, 1 week was devoted to science experiments. The goal of the science experiments was to test different planetary surface exploration strategies that included (1) a Mars mission simulation, (2) a science on the fly experiment, where the rover was kept moving 75% of the operation time. (The goal of this operation was to determine whether or not successful interpretation of the environment is related to the time spent on a target. The role of mobility in helping the interpretation was also assessed.) (3) a meteorite search using visual and instrumental methods to remotely identify meteorites in extreme environments, and (4) a time-delay experiment with and without using the panospheric camera. The results were as follow: the remote science team positively identified the main characteristics of the test site geological environment. The science on the fly experiment showed that the selection of appropriate targets might be even more critical than the time spent on a study area to reconstruct the history of a site. During the same operation the science team members identified and sampled a rock from a Jurassic outcrop that they proposed to be a fossil. The presence of paleolife indicators in this rock was confirmed later by laboratory analysis. Both visual and instrumental modes demonstrated the feasibility, in at least some conditions, of carrying out a field search for meteorites by using remote-controlled vehicles. Finally, metrics collected from the observation of the science team operations, and the use team members made of mission data, provided critical information on what operation sequences could be automated on board rovers in future planetary surface explorations.

The work addresses the manner in which the geologists organized themselves, how they allocated their time in different activities, how they formed and communicated scientific hypotheses, and the frequency with which they requested different types of data from the mission archive during the first 3 days of the mission. Eleven scientists from the NASA Ames Research Center and three of the five scientists who participated from their home institutions were videotaped as they worked throughout the 3-day experiment. The videotape record indicates that 46% of available person-hours were consumed in semistructured or formal meetings and that only 1% of their time was spent studying immersive, three-dimensional virtual reality models of the robot's surroundings. The remainder of their time was spent in unstructured work sessions in groups of two or three. Hypothesis formation and evolution patterns show a meager flow of information from the distributed science team to the on-site team and a bias against reporting speculative hypotheses. Analysis of the visual imagery received from the robot indicates that acquisition of the large panoramic information leads to high levels of redundancy in the data acquired. The scientists' archive requests indicate that small, specifically requested image targets were the most frequently accessed information. The work suggests alternative organizational structures that would expedite the flow of information within the geologic team. It also advocates emphasizing specific science targets over high-resolution, stereoscopic, panoramic imaging when programming a mobile robot's onboard cameras.

Height data over the ice sheet were mainly from ERS-1 and Geosat radar altimetry. These data were corrected for a slope-dependent bias that had been identified in a previous study. The radar altimetry was supplemented with stereophotogrammetric data sets, synthetic aperture radar interferometry, and digitized cartographic maps over regions of bare rock and where gaps in the satellite altimeter coverage existed. The data were interpolated onto a regular grid with a spacing of approximately 1 km. The accuracy of the resultant digital elevation model over the ice sheet was assessed using independent and spatially extensive measurements from an airborne laser altimeter that had an accuracy of between 10 and 12 cm. In a comparison with the laser altimetry the digital elevation model was found to have a slope-dependent accuracy ranging from -1.04+ or -1.98 m to -0.06+ or -14.33 m over the ice sheet for a slope range of 0.0-1.0 degrees . The mean accuracy over the whole ice sheet was -0.33+ or -6.97 m. Over the bare rock areas the accuracy ranged from 20 to 200 m, dependent on the data source available. The new digital elevation model was used as an input data set for a positive degree day model of ablation. The new elevation model was found to reduce ablation by only 2% compared with using an older, 2.5-km resolution model, which suggests that resolution-induced errors in estimating ablation are no longer important.

The 1999 Marsokhod Field Experiment (MFE) was a Mars rover simulation designed in part to investigate the utility of visible/near-infrared and thermal infrared field spectrometers to contribute to the remote geological exploration of a Mars analog field site in the California Mojave Desert. The experiment simultaneously investigated the abilities of an off-site science team to effectively analyze and acquire useful imaging and spectroscopic data and to communicate efficiently with rover engineers and an on-site field team to provide meaningful input to rover operations and traverse planning. Experiences gained during the MFE regarding effective communication between different mission operation teams will be useful to upcoming Mars mission teams. Field spectra acquired during the MFE mission exhibited features interpreted at the time as indicative of carbonates (both dolomitic and calcitic), mafic rocks and associated weathering products, and silicic rocks with desert varnish-like coatings. The visible/near-infrared spectra also suggested the presence of organic compounds, including chlorophyll in one rock. Postmission laboratory petrologic and spectral analyses of returned samples confirmed that all rocks identified as carbonates using field measurements alone were calc-silicates and that chlorophyll associated with endolithic organisms was present in the one rock for which it was predicted. Rocks classified from field spectra as silicics and weathered rnafics were recognized in the laboratory as metamorphosed monzonites and diorite schists. This discrepancy was likely due to rock coatings sampled by the field spectrometers compared to fresh rock interiors analyzed petrographically, in addition to somewhat different surfaces analyzed by laboratory thermal spectroscopy compared to field spectra.

AN - 50152982; 2006-004951 AB - Laboratory, analytical, and simulation studies suggest that Martian dust clouds can become significantly charged via dust/dust contact electrification. If moderate-size dust clouds on Mars are like their terrestrial counterparts, they are expected to have the capacity to create electric fields in excess of 1 kV/m. As on Earth, there is an expectation that these storm-generated electric fields terminate into both the ground and the ionosphere, coupling directly to the capacitor created by these bounding surfaces. Such charged dust storms are expected to drive ionospheric and ground currents, which complete their current path through the "fairweather" atmosphere remote from the storm. This system forms a Martian atmospheric electric circuit analogous (but not identical) to that created in the terrestrial atmosphere via thunderstorms. Here we define the requirements on Martian dust storms and the surrounding environment to create such a global electric circuit and then model the system. We find that the variation in global electric field is a strong function of Martian season, with possible values ranging in excess of hundreds of volts per meter in the active storm season (southern summer) to less than a volt per meter during the nonstorm season.

This comparison is used to determine methods that enhance the ability of a remote team using a rover to determine the geology and paleoclimate of a landing site analogous to sites that may be encountered during the Mars Surveyor Program. The mobility of the field geologists and their ability to rapidly gain visual and physical data from the field site give an immediate confidence to their interpretation of the geology. The finite time of teleoperation and the initial decisions and mechanical problems that caused the rover to linger and collect data in a small area of the test site for the first 5 days of the test limited the ability of the remote science team to gain a similar confidence. Nevertheless, by appropriate use of "orbital" and "descent" images as well as the rover's science pay load, the remote science team interpreted the present and former climates, the geology and geological history, and present-day biology relatively accurately. The few erroneous interpretations by the remote team resulted in part from biases brought to the test about the nature of the geology that was likely to be encountered. Data quality and variety also impacted the quality of the geological interpretations. Significant misinterpretations in the remotely determined geology resulted from the lack of detail in the optical imagery, a less than optimal understanding of the site's topography, and misinterpretation of some infrared data. All in all, this field test showed that the geology, paleoclimate, and biology of a site can be assessed to a reasonable level of confidence using a remotely controlled vehicle. It also showed that it is both feasible and desirable for a distributed science team to participate in long science missions from home institutions, as long as data flows efficiently to and from these institutions.

Satellite images and simulated descent images provided information about the regional setting. The landing zone was on an alluvial apron flanking a mountain block to the west and a playa surface to the east. Rover color images, infrared spectra analysis of the mountains, and the apron surface provided insight into the rock composition of the nearby mountains. From the return data the geomorphology team interpreted the region to consist of compressionally deformed, ancient marine sediments and igneous rocks exposed by more recent extensional tectonics. Unconsolidated alluvial materials blanket the lower flanks of the mountains. An ancient shoreline cut into alluvial material marks a high stand of water during a past, wetter climate period. Playa sediments floor a present-day, seasonally, dry lake. Observations made by the rover using panoramic and close-up (hand specimens-scale) image data and color scene data confirmed the presence of boulders, cobbles, and fines of various provinces. Rover traverses to sites identified as geologically distinct, such as fan, channel, shoreline, and playa, provided useful clues to the geologic interpretations. Analysis of local rocks was given context only through comparison with distant geologic features. These results demonstrated the importance of a multifaceted approach to site interpretation through comparison of interpretations derived by differing geologic techniques.

The science team requested the collecting of the boulder that was returned for laboratory analysis. This analysis confirmed the evidence of paleolife. As the first fossil identified and sampled by a remotely located science team using a rover, we use the case of sample I-250697 to describe the process, both in the field and later in the laboratory during the rock analysis, which led to the identification, characterization, and confirmation of the evidence of paleolife evidence in I-250697. We point out the lessons that this case provides for future Mars sample return missions. Copyright 2001 by the American Geophysical Union.

This system consists of a set of feature-extraction algorithms that operate in conjunction with a rule-based system to identify carbonates on the basis of presence and characteristics of absorption bands near 2.33 and 2.5 mu m. This autonomous system was tested during the February 1999 Marsokhod field operations. While performance was compromised to some extent by noise problems associated with the spectrometer, the autonomous system successfully rejected all noisy spectra. Among the nonnoisy spectra that it accepted, it identified carbonates with a success rate of 70% compared with the performance of the field team, a success rate of 82-90% compared with the performance of the remote science team, and a false positive rate of 0%.

The payload (Descent Imager, PanCam, Mini-TES, and Robotic Arm Camera), data volumes, and data transmission/receipt windows simulated those planned for the Mars Surveyor mission selected for 2001. A central mast with a pan and tilt platform at 150 cm height carried a high-resolution color stereo imager to simulate the PanCam and a visible/near-infrared fiberoptic spectrometer (operating range 0.35-2.5 mu m). Monochrome stereo navigation cameras were mounted on the mast and the front and rear of the rover near the wheels. A field portable infrared spectroradiometer (operating range 8-14 mu m) simulated the Mini-TES. A Robotic Arm Camera, capable of close-up color imaging at 23 mu m/pixel resolution, was used in conjunction with the excavation of a trench into the subsurface. The science team was also provided with simulated images from the Mars Descent Imager and orbital panchromatic and multispectral imaging of the site obtained with the French SPOT, airborne Thermal Infrared Mapping Spectrometer, and Landsat Thematic Mapper instruments. Commands sequences were programmed and sent daily to the rover, and data returned were limited to 40 Mbits per communication cycle. During the simulated mission, 12 commands were uplinked to the rover, it traversed approximately 90 m, six sites were analyzed, 11 samples were collected for laboratory analysis, and over 5 Gbits of data were collected. Twenty-two scientists, unfamiliar with the location of the field site, participated in the science mission from a variety of locations, accessing data via the World Wide Web. Remote science interpretations were compared with ground truth from the field and laboratory analysis of collected samples. Using this payload and mission approach, the science team synergistically interpreted orbital imaging and infrared spectroscopy, descent imaging, rover-based imaging, infrared spectroscopy, and microscopic imaging to deduce a consistent and largely correct interpretation of the geology, mineralogy, stratigraphy, and exobiology of the site. Use of imaging combined with infrared spectroscopy allowed source outcrops to be identified for local rocks on an alluvial fan. Different lithologies were distinguished both near the rover and at distances of hundreds of meters or more. Subtle differences such as a contact between dolomite and calcite were identified at a distance of 0.5 km. A biomarker for endolithic microbiota, a plausible life form to be found on Mars, was successfully identified. Microscopic imaging of soils extracted from the surface and subsurface allowed the mineralogy and fluvial history of the trench site to be deduced.

It is designed to take both panoramic and microscopic images in order to gather data on the morphology and mineralogy of surface materials. In order to demonstrate these capabilities, a field test was conducted at Silver Lake playa in the Mojave Desert. The test consisted of going to a remote site unknown to the science team and providing that team with a data set of RAC panoramic, anaglyph, and microscopic images similar to what would be available during an actual landing. With only this information the science team attempted a determination of the position and the geology of the field test site. Using panoramic and anaglyph images provided by RAC, in conjunction with overflight images simulating data from a descent camera, the landing site for the field test was determined within 50 m of the actual site as lying near both a playa and an alluvial fan. Images of samples from the surface and within the trench revealed grain morphology, texture, and mineralogy indicating a soil dominated by quartz and feldspar, interspersed with a minor mafic component. Grain-size distribution was bimodal, with small, rounded to subrounded grains dominant at lower depths and larger, more angular grains more plentiful near the surface. This mineralogy is confirmed by the geology of the site and the data provided by the descent images and mid-IR measurements. RAC has demonstrated its ability to image the local geology and identify the major mineralogic components of an unknown site. These abilities will be crucial in understanding both the macroscopic and the microscopic geology of future Mars landing sites. This test also has demonstrated the crucial link between RAC data and complementary data sets such as context images and compositional data that can support the mineralogic observations made by RAC.

As part of this mission, a test was made of strategies and analytical techniques for identifying past or present life in environments expected to be present on Mars. A combination of visual clues from high-resolution images and the detection of an important biomolecule (chlorophyll) with visible/near-infrared (NIR) spectroscopy led to the successful identification of a rock with evidence of cryptoendolithic organisms. The sample was identified in high-resolution images (3 times the resolution of the Imager for Mars Pathfinder camera) on the basis of a green tinge and textural information suggesting the presence of a thin, partially missing exfoliating layer revealing the organisms. The presence of chlorophyll bands in similar samples was observed in visible/NIR spectra of samples in the field and later confirmed in the laboratory using the same spectrometer. Raman spectroscopy in the laboratory, simulating a remote measurement technique, also detected evidence of carotenoids in samples from the same area. Laboratory analysis confirmed that the subsurface layer of the rock is inhabited by a community of coccoid Chroococcidioposis cyanobacteria. The identification of minerals in the field, including carbonates and serpentine, that are associated with aqueous processes was also demonstrated using the visible/NIR spectrometer. Other lessons learned that are applicable to future rover missions include the benefits of web-based programs for target selection and for daily mission planning and the need for involvement of the science team in optimizing image compression schemes based on the retention of visual signature characteristics.

A more intelligent rover could, for example, automatically select targets of interest (e.g., rocks, layers), return spectral or high-resolution image data of these targets at the same time, remove less interesting or redundant parts of images before transmitting them, and provide compact information or representations of its environment. Three prototype algorithms, a horizon detector, a rock detector, and a layer detector have been developed and tested during the 1999 Marsokhod rover field test in Silver Lake, California. The results are encouraging and demonstrate the potential savings in time as well as the potential increase in the amount of relevant science data returned in each command cycle.

The 3D Goddard Cumulus Ensemble cloud-resolving model is coupled with the Goddard Parameterization for Land-Atmosphere-Cloud Exchange land surface model, thus providing a tool to simulate more realistically land surface-atmosphere interaction and convective initiation. Eight simulations are conducted with either straight or curved coastlines, initially homogeneous soil moisture or initially variable soil moisture, and initially homogeneous horizontal winds or initially variable horizontal winds (land breezes). An additional simulation is performed to assess the role of Lake Okeechobee on convective development. All model simulations capture the diurnal evolution and general distribution of sea-breeze-initiated precipitation over central Florida. The distribution of initial soil moisture influences the timing and location of subsequent precipitation. Soil moisture acts as a moisture source for the atmosphere, increases the convectively available potential energy, and thus preferentially focuses heavy precipitation over existing wet soil. Soil moisture-induced mesoscale circulations do not produce heavy precipitation. Coastline curvature has a major impact on the timing and location of precipitation. Earlier low-level convergence occurs inland of convex coastlines, and subsequent heavy precipitation occurs earlier in simulations with curved coastlines. Early-morning land breezes influence the timing of precipitation by modifying low-level convergence. Because of nonlinear interaction between coastline curvature and soil moisture, the highest peak accumulated rainfall and highest peak rain rates occur in simulations with both coastline curvature and initial soil moisture variations. Lake Okeechobee influences the timing and location of precipitation because of strong lake-breeze circulations.

Because of their influence on both the innate and the acquired arms of immunity, a defect in DC would be expected to result in a broad impairment of immune function, not unlike that observed in astronauts during or after space flight. In the study reported here, we investigated whether DC generation and function are altered in a culture environment that models microgravity, i.e., the rotary-cell culture system (RCCS). We observed that RCCS supported the generation of DC identified by morphology, phenotype (HLA-DR+ and lacking lineage-associated markers), and function (high allostimulatory activity). However, the yield of DC from RCCS was significantly lower than that from static cultures. RCCS-generated DC were less able to phagocytose Aspergillus fumigatus conidia and expressed a lower density of surface HLA-DR. The proportion of DC expressing CD80 was also significantly reduced in RCCS compared to static cultures. When exposed to fungal antigens, RCCS-generated DC produced lower levels of interleukin-12 and failed to upregulate some costimulatory/adhesion molecules involved in antigen presentation. These data suggest that DC generation, and some functions needed to mount an effective immune response to pathogens, may be disturbed in the microgravity environment of space.

These interannual variations were detected and analyzed for 1982-90 with a multivariate spectral method. The two most dominant signals for 1982-90 had periods of about 2.6 and 3.4 yr. Signals centered at 2.6 years per cycle corresponded to variations in the El Nino-Southern Oscillation index and explained about 28% of the variance in anomalies of SST, land surface air temperature, precipitation, and vegetation; these signals were most pronounced in 1) SST anomalies in the eastern equatorial Pacific Ocean, 2) land surface vegetation and precipitation anomalies in tropical and subtropical regions, and 3) land surface vegetation, precipitation, and temperature anomalies in North America. Signals at 3.4 years per cycle corresponded to variations in the North Atlantic oscillation index and explained 8.6% of the variance in the combined datasets; their occurrence was most pronounced in 1) Atlantic SST anomalies, 2) in land surface temperature and vegetation anomalies in Europe and eastern Asia, and 3) in precipitation and vegetation anomalies in sub-Saharan Africa, southern Africa, and eastern North America. Anomalies in vegetation were positively related to anomalies in precipitation throughout the Tropics and subtropics and in midlatitudes in the central parts of continents. Anomalies in vegetation and temperature were positively linked in coastal temperate climates such as in Europe and eastern Asia. These associations between temperature and vegetation may be explained by the sensitivity of the length of growing season to variations in temperature.

The method projects the Kalman filter equations onto a subspace defined by the eigenvalue decomposition of the error forecast matrix, allowing its application to high-dimensional systems. The Zebiak and Cane model couples a linear, reduced-gravity ocean model with a single, vertical-mode atmospheric model. The compatibility between the simplified physics of the model and each observed variable is studied separately and together. The results show the ability of the empirical orthogonal functions (EOFs) of the model to represent the simultaneous value of the wind stress, SST, and sea level, when the fields are limited to the latitude band 10 degree S-10 degree N, and when the number of EOFs is greater than the number of statistically significant modes. In this first application of the Kalman filter to a coupled ocean-atmosphere prediction model, the sea level fields are assimilated in terms of the Kelvin and Rossby modes of the thermocline depth anomaly. An estimation of the error of these modes is derived from the projection of an estimation of the sea level error over such modes. The ability of the method to reconstruct the state of the equatorial Pacific and to predict its time evolution is shown. The method is quite robust for predictions up to 6 months, and able to predict the onset of the 1997 warm event 15 months before its occurrence.

The NO is oxidized to NO sub(2), HNO sub(2), and HNO sub(3), which can then be removed in a wet scrubber. A pilot plant system that was designed, constructed, and operated at Kennedy Space Center confirmed previous results that H sub(2)O sub(2) is very effective at oxidizing NO; conversions of NO above 90% were obtained at temperatures of about 500 degree C (930 degree F) using mole ratios of H sub(2)O sub(2):NO sub(x) slightly above 1.0. The mole ratios of H sub(2)O sub(2)/NO sub(x) needed to obtain high conversions of NO were significantly lower in the pilot plant that they had been in previous laboratory studies, demonstrating that this process can be an economically feasible method for NO sub(x) control. The position of the injector and the type of atomization were very important to the efficient utilization of peroxide. When SO sub(2) was present in the flue gas, both NO and SO sub(2) were oxidized without increasing the demand for peroxide.

We examined the effect of urine volume on the risk of renal stone formation in 356 astronauts. Methods: Renal stone-forming risk was evaluated from 24-h urine samples collected from astronauts before and after 4- to 17-d Space Shuttle flights. Urinary chemistries were performed and the relative supersaturations of calcium oxalate, brushite, sodium urate, struvite, and uric acid saturation were calculated from the biochemical results. Results: Urinary supersaturation levels of stone-forming salts were inversely related to urinary output both before and after spaceflight. Urine volume > 2 L times d super(-1) reduced the risk of renal-stone development without affecting urinary citrate concentrations as compared with the increased risk observed in those astronauts who excreted urine volumes < L times d super(-1). Conclusion: Results from this study indicate that increasing daily urinary output alone is an effective countermeasure to reduce the renal stone-forming risk immediately after spaceflight. However, increasing urinary output during flight may not be entirely effective in minimizing the potential risk of renal stone formation due to the changes in the urine chemistry in astronauts exposed to microgravity.

These measurements allowed the comparison of simultaneous ocean and land net primary production (NPP) responses to a major El Nino to La Nina transition. Between September 1997 and August 2000, biospheric NPP varied by 6 petagrams of carbon per year (from 111 to 117 petagrams of carbon per year). Increases in ocean NPP were pronounced in tropical regions where El Nino-Southern Oscillation (ENSO) impacts on upwelling and nutrient availability were greatest. Globally, land NPP did not exhibit a clear ENSO response, although regional changes were substantial.

Computed denitrification profiles for one Antarctic and two Arctic cold winters are presented. The vertical range over which denitrification occurs is normally quite deep in the Antarctic but limited in the Arctic. A 4 kelvin decrease in the temperature of the Arctic stratosphere due to anthropogenic and/or natural effects can trigger the occurrence of widespread severe denitrification. Ozone loss is amplified in a denitrified stratosphere, so the effects of falling temperatures in promoting denitrification must be considered in assessment studies of ozone recovery trends.

During intense fires over Indonesia (August to November 1997), ozone plumes, decoupled from the smoke below, extended as far as India. This ozone overlay a regional ozone increase triggered by atmospheric responses to the El Nino and Indian Ocean Dipole. Tropospheric ozone and smoke aerosol measurements from the Nimbus 7 TOMS instrument show El Nino signals but no tropospheric ozone trend in the 1980s. Offsets between smoke and ozone seasonal maxima point to multiple factors determining tropical tropospheric ozone variability.

AN - 71380213; 12715824 AB - For interpretation of results from future biological experiments in the International Space Station (ISS), radiation doses received by the biological samples must be accurately determined. This paper demonstrates that small integrating detectors, such as thermoluminescent dosemeters (TLDs) and glasses, can be used in a simple way for evaluation of biological doses from space radiation. Statistical errors (type-A uncertainty) of this method would be satisfactorily small relative to those generally observed in biological responses. Permissible levels of systematic errors (type-B uncertainty) should depend on both dosimetry purpose (most-probable or conventional evaluation) and reproducibility of the biological responses. It is expected that this method will be suitably applied to future experiments in the ISS where any instruments have to be small-scale, light-weight, physico-chemically stable and simple in handling.

The unanswered question is whether these complaints are really due to poor cabin air quality or to other factors inherent inflight such as lowered barometric pressure, hypoxia, low humidity, circadian dysynchrony, work/rest cycles, vibration etc. This paper will review some aspects relevant to cabin air quality such as carbon dioxide (CO2), carbon monoxide (CO), ozone (O3), particulates, and microorganisms as well as the cabin ventilation system to discern if there is a possible cause and effect of illness contracted inflight. The paper will conclude with recommendations on how the issue of cabin air quality may be resolved.

Therefore, it is important to judge correctly the biological effect of space radiation for human health. In addition, research for space radiation might give us useful information concerning birth and evolution of lives on the earth. Here, we described a view of the future about space experiments at an International Space Station. Therefore, we desire to educate the space researcher of the next generation for importance of research for space radiation.

AN - 71279012; 11858273 AB - A revolutionary new concept for the early establishment of robust, self-sustaining Martian colonies is described. The colonies would be located on the North Polar Cap of Mars and utilize readily available water ice and the CO2 Martian atmosphere as raw materials to produce all of the propellants, fuel, air, water, plastics, food, and other supplies needed by the colony. The colonists would live in thermally insulated large, comfortable habitats under the ice surface, fully shielded from cosmic rays. The habitats and supplies would be produced by a compact, lightweight (~4 metric tons) nuclear powered robotic unit termed ALPH (Atomic Liberation of Propellant and Habitat), which would land 2 years before the colonists arrived. Using a compact, lightweight 5 MW (th) nuclear reactor/steam turbine (1 MW(e)) power source and small process units (e.g., H2O electrolyzer, H2 and O2 liquefiers, methanator, plastic polymerizer, food producer, etc.) ALPH would stockpile many hundreds of tons of supplies in melt cavities under the ice, plus insulated habitats, to be in place and ready for use when the colonists landed. With the stockpiled supplies, the colonists would construct and operate rovers and flyers to explore the surface of Mars. ALPH greatly reduces the amount of Earth supplied material needed and enables large permanent colonies on Mars. It also greatly reduces human and mission risks and vastly increases the capability not only for exploration of the surrounding Martian surface, but also the ice cap itself. The North Polar Cap is at the center of the vast ancient ocean that covered much of the Martian Northern Hemisphere. Small, nuclear heated robotic probes would travel deep (1 km or more) inside the ice cap, collecting data on its internal structure, the composition and properties of the ancient Martian atmosphere, and possible evidence of ancient life forms (microfossils, traces of DNA, etc.) that were deposited either by wind or as remnants of the ancient ocean. Details of the ALPH system, which is based on existing technology, are presented. ALPH units could be developed and demonstrated on Earth ice sheets within a few years. An Earth-Mars space transport architecture is described, in which Mars produced propellant and supplies for return journeys to Earth would be lifted with relatively low DeltaV to Mars orbit, and from there transported back to Earth orbit, enabling faster and lower cost trips from Earth to Mars. The exploration capability and quality of life in a mature Martian colony of 500 persons located on the North Polar Cap is outlined. c2001 International Astronautical Federation.

AN - 52233067; 2001-036605 AB - Prominent maxima in black shale abundance and in black shale/total shale ratio occur at 2.0-1.7 Ga, with less prominent peaks in the Late Neoproterozoic (800-600 Ma) and in the Late Archean (2.7-2.5 Ga). Peaks in chemical index of alteration (CIA) of shales at the same times suggest corresponding warm paleoclimates. The peaks in CIA and black shale abundance are correlated in time at a 94% confidence level. The black shale and CIA peaks may reflect the combined effects of mantle superplume events and supercontinent formation at 2.7 and 1.9 Ga. Mantle superplume events may have introduced large amounts of CO (sub 2) into the atmosphere-ocean system, increasing depositional rates of carbon and increasing global warming. Increased black shale deposition may reflect some combination of: (1) increased oceanic hydrothermal fluxes (introducing nutrients); (2) anoxia on continental shelves; and (3) disrupted ocean currents. The apparent absence of carbon isotope anomalies at these times reflects an increase in the deposition and burial rate of both reduced and oxidized carbon. Peaks in black shale abundance at approximately 2.1 Ga and 800-600 Ma correlate with peaks in delta (super 13) C in marine carbonates, increases in atmospheric oxygen, and with high CIA values in shales. These are all consistent with higher rates of organic carbon burial in black shales at these times. These peaks may record the breakup of supercontinents at 2.2-2.0 Ga and again at 800-600 Ma, which resulted in increased numbers of partially closed marine basins, disruption of ocean currents, and increased hydrothermal vents at ocean ridges, all of which led to widespread anoxia.

Chemically zoned carbonate globules and Fe sulfides were rapidly precipitated under low-temperature (150 degrees C), hydrothermal, and non-equilibrium conditions from multiple fluxes of Ca-Mg-Fe-CO (sub 2) -S-H (sub 2) O solutions that have different compositions. Chemically pure, single-domain, defect-free magnetite crystals were formed by subsequent decomposition of previously precipitated Fe-rich carbonates by brief heating to 470 degrees C. The sequence of hydrothermal precipitation of carbonates from flowing CO (sub 2) -rich waters followed by a transient thermal event provides an inorganic explanation for the formation of the carbonate globules, magnetite, and Fe sulfides in ALH84001. In separate experiments, kinetically controlled (super 13) C enrichment was observed in synthetic carbonates that is similar in magnitude to the (super 13) C enrichment in ALH84001 carbonates.

These equilibria can provide the framework for a better understanding of relevant titanite-bearing natural assemblages. In addition, such equilibria can constrain the variables that operate during crystallization of igneous and metamorphic rocks. Titanite-bearing assemblages with pyroxene(s), Fe-Mg-Ti ilmenite and spinel, olivine, and quartz are rare in metamorphic rocks but are common in igneous rocks where they are more commonly reported in plutonic than in volcanic rocks. Probably because, at high temperatures, titanite cannot coexist with the relative common in volcanic rocks sub-assemblage augite+orthopyroxene+olivine+spinel phase+ilmenite. Moreover, decreasing pressure and temperature conditions appear to favor titanite. Thus, it is not surprising that titanite is commonly observed in slowly cooled rocks, albeit, most typically in association with amphibole. We argue that the titanite+amphibole association is favored by high a (sub H2O) and, because a (sub H2O) typically increases during crystallization of a pluton, titanite+amphibole (and consequently titanite) is more common in plutonic than in volcanic rocks. We have used a modified version of the program QUILF that includes our thermodynamic data for titanite and appropriate titanite-bearing assemblages to estimate the equilibrium crystallization conditions of samples from: (1) a tonalite from the Myoken-Zan granitic complex in Japan; (2) the Sandwich Horizon in the Skaergaard intrusion in Greenland; (3) rhyodacites, dacites, and andesites from the Sajama, Porquesa, and Parinacota volcanoes in the Andes; (4) the Fish Canyon Tuff in Colorado; and (5) a quartz-rich, calc-silicate gneiss adjacent to the Horse Creek Anorthosite Complex in Wyoming. The calculations suggest that: (1) these titanite-bearing assemblages crystallized at values of f (sub O2) that ranged from slightly below FMQ to more than 3 logf (sub O2) units above FMQ at 500-800 degrees C; and (2) the stability of titanite is controlled by T, f (sub O2) , a (sub SiO2) , and the compositions of the coexisting oxides and silicates.

As we found in our earlier studies on the photoprocessing of coronene in H (sub 2) O ice, aromatic alcohols and ketones (quinones) were formed. The regiochemistry of the reactions is described and leads to specific predictions of the relative abundances of various oxidized naphthalenes that should exist in meteorites if interstellar ice photochemistry influenced their aromatic inventory. Since oxidized PAHs are present in carbon-rich meteorites and interplanetary dust particles (IDPs), and ubiquitous in and fundamental to biochemistry, the delivery of such extraterrestrial molecules to the early Earth may have played a role in the origin and evolution of life.

PAT 91501, originally classified as an L7 chondrite, is rather a unique, near total impact melt from the L-chondrite parent body. Lewis Cliff 88663 was originally classified as an "achondrite (?)", but we find that it is a very weakly shocked L7 chondrite. PAT 91501 is an unshocked, homogeneous, igneous-textured ultramafic rock composed of euhedral to subhedral olivine, low-Ca pyroxene, augite and chrome-rich spinels with interstitial albitic plagioclase and minor silica-alumina-alkali-rich glass. Only approximately 10% relic chondritic material is present. Olivine grains are homogeneous (Fa (sub 25.2-26.8) ). Low-Ca pyroxene (Wo (sub 1.9-7.2) En (sub 71.9-78.2) Fs (sub 19.9-20.9) )) and augite (Wo (sub 29.8-39.0) En (sub 49.2-55.3) Fs (sub 11.8-14.9) ) display a strong linear TiO (sub 2) -Al (sub 2) O (sub 3) correlation resulting from igneous fractionation. Plagioclase is variable in composition; Or (sub 3.0-7.7) Ab (sub 79.8-84.1) An (sub 8.2-17.2) . Chrome-rich spinels are variable in composition and zoned from Cr-rich cores to Ti-Al-rich rims. Some have evolved compositions with up to 7.9 wt% TiO (sub 2) . PAT 91501 bulk silicate has an L-chondrite lithophile element composition except for depletions in Zn and Br. Siderophile and chalcophile elements are highly depleted due to sequestration in centimeter-size metal-troilite nodules. The minerals in LEW 88663 are more uniform in composition than those in PAT 91501. Olivine grains have low CaO and Cr (sub 2) O (sub 3) contents similar to those in L5-6 chondrites. Pyroxenes have high TiO (sub 2) contents with only a diffuse TiO (sub 2) -Al (sub 2) O (sub 3) correlation. Low-Ca pyroxenes are less calcic (Wo (sub 1.6-3.1) En (sub 76.5-77.0) Fs (sub 20.4-21.4) ), while augites (Wo (sub 39.5-45.6) En (sub 46.8-51.1) Fs (sub 7.6-9.4) ) and plagioclases (Or (sub 2.6-5.7) Ab (sub 74.1-83.1) An (sub 11.2-23.3) ) are more calcic. Spinels are homogeneous and compositionally similar to those in L6 chondrites. LEW 88663 has an L-chondrite bulk composition for lithophile elements, and only slight depletions in siderophile and chalcophile elements that are plausibly due to weathering and/or sample heterogeneity.

The final depletion of this leftover population would cause an extended bombardment of all of the terrestrial planets, slowly decaying with a timescale on the order of 60 Ma. Because of the large impact velocities dictated by the high inclinations, these projectiles would produce craters much larger than those formed by asteroids of equal size on typical current near-Earth asteroid orbits: on the Moon, basins could have been formed by bodies as small as 20 km in diameter, and 10 km craters could be produced by 400 m impactors. To account for the observed lunar crater record, the initial population of highly-inclined leftovers would need to be a few times that presently in the main asteroid belt, at all sizes, in agreement with the simulations of the primordial sculpting of both these populations. If a terminal lunar cataclysm (a spike in the crater record approximately 3.9 Ga ago) really occurred on the Moon, it was not caused by the highly-inclined leftover population, because of the monotonic decay of the latter.

The 7.04 kg specimen was found in ca. 1977 on the farm Waterval 64, about 30 km from the town of Merweville ( approximately 375 km northeast of Cape Town). Our research group confirmed the identity of the stone as a meteorite in 1997, and obtained a approximately 1.5 kg portion for study and classification. Externally, the specimen shows a few regmaglypts and a reddish-brown, weathered fusion crust. The sawn internal surfaces show that terrestrial weathering effects, which render a dark brownish colour to the specimen, have penetrated up to 4 to 5 cm into the meteorite. The relatively unweathered interior is light orange-brown in colour. Petrographically, the specimen shows a dominantly recrystallised texture, with a few recognisable chondrules or chondrule fragments. Shock stage is estimated at S2, and weathering grade is W2. Microprobe analyses yield: olivine (Fa (sub 23.32 + or - 0.612) , PMD = 0.52, n = 13), orthopyroxene (Fs (sub 20.59 + or - 0.54) , n = 15), kamacite (Ni = 6.48 + or - 0.24 wt.%, Co = 0.94 + or - 0.14 wt.%, n = 15), taenite (Ni = 28.9 + or - 2.3 wt.%, Co = 0.29 + or - 0.08 wt.%, n = 3), troilite (Ni = 0.10 + or - 0.11 wt.%, n = 17) and chromite (Cr/(Cr+Al) = 0.860 + or - 0.003, n = 4). No recognisable feldspar or glass is present in our thin sections of Merweville. The dominantly recrystallised but partial preservation of chondrules, apparent absence of glass, and the relative uniformity of olivine and pyroxene compositions are all consistent with classification of Merweville as petrologic type 5. Chemical and mineralogical data for the "unweathered" portion of the meteorite fall best within the L group. We conclude that Merweville is an L5 chondrite. This new specimen increases the inventory of known South African meteorites to a total of 48.

Most of the heat within the very young Earth was lost quickly to space while the surface was still quite hot. As it cooled, the Earth's surface passed monotonically through every temperature regime between silicate vapor to liquid water and perhaps even to ice, eventually reaching an equilibrium with sunlight. Inevitably the surface passed through a time when the temperature was around 100 degrees C at which modern thermophile organisms live. How long this warm epoch lasted depends on how long a thick greenhouse atmosphere can be maintained by heat flow from the Earth's interior, either directly as a supplement to insolation, or indirectly through its influence on the nascent carbonate cycle. In both cases, the duration of the warm epoch would have been controlled by processes within the Earth's interior where buffering by surface conditions played little part. A potentially evolutionarily significant warm period of between 105 and 107 years seems likely, which nonetheless was brief compared to the vast expanse of geological time.

An analytic model to account for this component of the EM bias is developed here under a two-scale two-dimensional hydrodynamic assumption. Following the principle of wave action balance, a standard hydrodynamic modulation transfer function is used to establish that the longer modulating waves enter the EM bias formulation not only through their elevation and slope variables but also through their quadratures. These latter contributions help to explain the role of long-wave slope and orbital velocity fields within the EM bias problem. Simplified analytical expressions are derived using linear Gaussian statistics for both modulating and modulated waves. For the sake of completeness an outline of the possible extension to nonlinear interacting waves is provided. Copyright 2001 by the American Geophysical Union.

Aircraft sensors measured near-surface atmospheric turbulence and, at the same time, variations in sea surface roughness using laser and radar. The aircraft turbulence observations indicate a coherent secondary flow consistent with boundary layer roll vortices of crosswind scale 1.5-2.0 km. Modulation in measured laser and radar-inferred sea surface slope variance occurs at similar scales. Remarkable correlation is found between the radar backscatter and near-surface wind speed data, showing that the short wave slope variance is responsive to these large eddies. Associated small but periodic changes in wind direction do not appear to impact the short wave slope signature. Differentiation between short- and intermediate-scale wave roughness using aircraft laser and radar data leads us to conclude that observed fluctuations in intermediate-scale wave slope were not directly linked to the local wind. A synthetic aperture radar (SAR) image was acquired by the Canadian Space Agency's RADARSAT coincident with the aircraft measurements. Widespread streaking in the SAR image suggests the surface impacts of atmospheric longitudinal rolls. Our aircraft results indicate that the dominant term dictating SAR backscatter modulations at the eddy scale of 1-2 km is the fluctuation of the along-wind velocity, nominally associated with regions of near-surface convergence or divergence. Wind speed fluctuations of 7-10% estimated from the SAR and aircraft radar are consistent with the aircraft's measured variations in near-surface wind speed.

The energy density of the polar cusp plasma is expected to be controlled by the component of the unshocked solar wind dynamic pressure along the normal to the cusp/magnetosheath interface. The factors controlling this angle are the local time of the observation and the dipole tilt angle. We use Polar observations of the magnetic field and plasma to identify the polar cusp, and the change in magnetic pressure in the cusp to calculate the peak diamagnetic pressure of the plasma. As expected this pressure is directly proportional to the solar wind dynamic pressure in quantitative agreement with expectations. When the dipole tilts more toward the Sun, the angle between the solar wind flow and the magnetopause normal is smaller, and the pressure is higher, and when it tilts away from the Sun, the pressure is less. For large tilts away from the Sun, for local times far away from noon and for low solar wind dynamic pressure the diamagnetic depression marking the polar cusp is too weak to be resolved by the magnetometer.

AN - 50081001; 2006-005757 AB - The mineralogical and elemental composition of dust size fractions (<2 and <5 mu m) of eight samples of phyllosilicate-poor palagonitic tephra from the upper slopes of Mauna Kea Volcano (Hawaii) were studied by X-ray diffraction (XRD), X-ray fluorescence (XRF), visible and near-IR reflectance spectroscopy, Moessbauer spectroscopy, magnetic properties methods, and transmission electron microscopy (TEM). The palagonitic dust samples are spectral analogues of Martian bright regions at visible and near-IR wavelengths. The crystalline phases in the palagonitic dust are, in variable proportions, plagioclase feldspar, Ti-containing magnetite, minor pyroxene, and trace hematite. No basal reflections resulting from crystalline phyllosilicates were detected in XRD data. Weak, broad XRD peaks corresponding to X-ray amorphous phases (allophane, nanophase ferric oxide (possibly ferrihydrite), and, for two samples, hisingerite) were detected as oxidative alteration products of the glass; residual unaltered glass was also present. Moessbauer spectroscopy showed that the iron-bearing phases are nanophase ferric oxide, magnetite/titanoinagnetite, hematite, and minor glass and ferrous silicates. Direct observation by TEM showed that the crystalline and X-ray amorphous phases observed by XRD and Moessbauer are normally present together in composite particles and not normally present as discrete single-phase particles. Ti-bearing magnetite occurs predominantly as 5-150 nm particles embedded in noncrystalline matrix material and most likely formed by crystallization from silicate liquids under conditions of rapid cooling during eruption and deposition of glassy tephra and prior to palagonitization of glass. Rare spheroidal halloysite was observed in the two samples that also had XRD evidence for hisingerite. The saturation magnetization J (sub s) and low-field magnetic susceptibility for bulk dust range from 0.19 to 0.68 Am (super 2) /kg and 3.4 X 10 (super -6) to 15.5 X 10 (super -6) m (super 3) /kg at 293 K, respectively. Simulation of the Mars Pathfinder Magnet Array (MA) experiment was performed on Mauna Kea Volcano in areas with phyllosilicate-poor palagonitic dust and with copies of the Pathfinder MA. On the basis of the magnetic properties of dust collected by all five MA magnets and the observation that the Pathfinder MAs collected dust on the four strongest magnets, the value for the saturation magnetization of Martian dust collected in the MA experiments is revised downward from 4 + or - 2 Am (super 2) /kg to 2.5 + or - 1.5 Am (super 2) /kg. The revised value corresponds to 2.7 + or - 1.6 wt % magnetite if the magnetic mineral is magnetite (using J (sub s ) = 92 Am (super 2) /kg for pure magnetite, Fe (sub 3) O (sub 4) ) or to 5.0 + or - 3.0 to 3.4 + or - 2.0 wt % maghemite if the magnetic mineral is pure maghemite (using J (sub s ) = 50 to 74 Am (super 2) /kg for pure maghemite, gamma -Fe (sub 2) O (sub 3) ). Comparison of the magnetic properties of bulk Mauna Kea palagonitic dust to those for dust collected by MA magnets shows that the MA magnets extracted (culled) a subset (25-34 wt %) of composite magnetic particles from bulk dust. The extent of culling of Martian dust is not well constrained. Because the Mauna Kea palagonitic dust satisfies the essential constraints of the Pathfinder magnetic properties experiment (composite and magnetic particles capable of being collected by five MA magnets), a working hypothesis for the strongly magnetic mineral present in Martian dust and soil is magnetite (possibly Ti-bearing) formed by rapid crystallization from silicate liquids having volcanic and/or impact origins. Subsequent palagonitization of the glass produces the nanophase ferric oxide phases that dominate the spectral properties of Martian bright regions at visible and near-IR wavelengths. Magnetic and phyllosilicate-poor palagonitic dust from Mauna Kea Volcano is thus a spectral and magnetic analogue for magnetic Martian dust. Copyright 2001 by the American Geophysical Union.

Because the radar operates at an attenuating wavelength, one of the principal issues concerns the accuracy of the attenuation correction algorithms. One way to test these algorithms is by means of a statistical method in which the probability distribution of rain rates at the high end is inferred by measurements at the low to intermediate range and by the assumption that the rain rates are lognormally distributed. Investigation of this method and the area-time integral methods using a global dataset provides an indication of how well methods of this kind can be expected to perform over different space-timescales and climatological regions using the sparsely sampled TRMM radar data. Identification of statistical relationships among the rain parameters and an understanding of the rain-rate distribution as a function of time and space may help to test the validity of the high-resolution rain-rate estimates.

Based on these modes, the impacts of the 1997-98 El Nino on major drought and flood occurrences over China have been assessed. The first mode can be identified with the growing phase of El Nino superimposed on a warming trend since the mid-1950s. This mode strongly influences rainfall over northern China. The second mode comprises a quasi-biennial (QB) variability manifested in alternate wet and dry years over the Yangtze River Valley (YRV) of central China. The third mode is dominated by a quasi-decadal oscillation in eastern China between the Yangtze River and the Yellow River, with an opposite tendency in southern China. Using a mode-by-mode reconstruction, the contributions of these leading modes to the 1997 and 1998 observed rainfall anomalies are evaluated. It is found that the severe drought in northern China, and to a lesser degree the flood in southern China, in 1997 is likely a result of the influence of anomalous SST forcing during the growing phase of the 1997-98 El Nino. The severe flood over YRV in 1998 is associated with the biennial tendency of basin-scale SST anomaly during the transition from El Nino to La Nina in 1997-98. In addition, the prolonged dry tendency over northern China and wet tendency over YRV since the 1970s may be associated with a long-term warming trend in the tropical Indian Ocean and western Pacific. The long-term dry background exacerbated the drought situation over northern China in 1997, and the wet background exacerbated the flood situation over YRV in 1998, under the impacts of the 1997-98 El Nino. In contrast, the rainfall variability in southern China is most chaotic, with no clear dominance of either El Nino or QB signals. The significance, reliability, and stability of these results are also discussed.

This model is called the GeoSail model. Tree shapes are described by cylinders or cones distributed over a plane. Spectral reflectance and transmittance of trees are calculated from the SAIL model to determine the reflectance of the three components of the geometric model: illuminated canopy, illuminated background, and shadowed background. Although the GeoSail model is relatively simple, calculations of canopy reflectance and fraction of intercepted photosynthetically active radiation (f sub(IPAR)) compared well with measurements collected in field experiments in forests in Minnesota and Oregon.

This foreign sand is often spread and shaped to mimic native beach slopes. However, nourished beaches differ from native in a multitude of properties. Some of these differences are in the compactness and hardness of sand, temperature, humidity, shear resistance, and grain size. All of these characteristics affect the microenvironment of sea turtle clutches, particularly gas exchange. This study looks at differences between the microenvironment of native versus renourished sands. The focus is on how these inherit differences affect gas exchange.

Continuing discoveries about life on Earth and the return of data suggesting the presence of liquid water environments on or under the surfaces of other planets and moons have combined to suggest the significant possibility that extraterrestrial life may exist in this solar system. Similarly, not since the Viking missions of the mid-1970s has there been as great an appreciation for the potential for Earth life to contaminate other worlds. Current plans for the exploration of the solar system include constraints intended to prevent biological contamination from being spread by solar-system exploration missions.

Why? Because in the past few decades we have come to realize that where there is liquid water on Earth, virtually no matter what the physical conditions, there is life. What we previously thought of as insurmountable physical and chemical barriers to life, we now see as yet another niche harbouring "extremophiles". This realization, coupled with new data on the survival of microbes in the space environment and modelling of the potential for transfer of life between celestial bodies, suggests that life could be more common than previously thought. Here we examine critically what it means to be an extremophile, and the implications of this for evolution, biotechnology and especially the search for life in the Universe.

AN - 85354122; pmid-11281104 AB - Under certain circumstances, external stimuli will elicit an involuntary shift of spatial attention, referred to as attentional capture. According to the contingent involuntary orienting account (Folk, Remington, & Johnston, 1992), capture is conditioned by top-down factors that set attention to respond involuntarily to stimulus properties relevant to one's behavioral goals. Evidence for this comes from spatial cuing studies showing that a spatial cuing effect is observed only when cues have goal-relevant properties. Here, we examine alternative, decision-level explanations of the spatial cuing effect that attribute evidence of capture to postpresentation delays in the voluntary allocation of attention, rather than to on-line involuntary shifts in direct response to the cue. In three spatial cuing experiments, delayed-allocation accounts were tested by examining whether items at the cued location were preferentially processed. The experiments provide evidence that costs and benefits in spatial cuing experiments do reflect the on-line capture of attention. The implications of these results for models of attentional control are discussed.

AN - 72288628; 11712559 AB - To observe and investigate the variation and heredity of the offspring of dry seeds of sorghum carried by satellite hence to select excellent mutants and to cultivate directivity new varieties for production application. Dry seeds of Tanghui 28, a sorghum restorer line, were carried to the space on board a recoverable satellite for 15 d. After recovery the seeds were planted in the field to study the growth dynamics and change of agricultural characters. Variations of characters such as dwarfing of stalk, significant increase grain weight per spike etc were observed in SP1 generation. Wide separation occurred in SP2 generation. Regardless that only non-significant separation of disease resistance and a very little variation of glum color were observed, the other characters varied significantly, and a super large panicle type varied line was obtained. Its spike length was 4 cm longer, and grain weight per spike was 58.5 g more than the control. It may be considered that the variation of sorghum seeds induced by the space conditions was heritable to the offsprings. Therefore, exposure to the space environment could be used as a method for mutagenic seeds breeding.

AN - 72285867; 11712557 AB - To investigate the inhibitory effects of tea polyphenols (TP) and Vitamin C (Vit C) on FeSO4-cysteine induced lipid peroxidation in isolated human plasma and carbon tetrachloride (CCl4) induced liver free radical injury in mice. The experiment included two parts: (1) In FeSO4-cysteine induced lipid peroxidation system of isolated human plasma, malondialdehyde (MDA) content was detected after administration of different concentrations of TP (0.3 ~ 8.1 mg/L, as C ~ F group) and Vit C (3 ~ 81 mg/L, as G ~ J group) respectively; (2) Thirty-six male Kunming mice were randomly divided into four groups: control group (A), CCl4 damage group (B), TP protection group (C) and Vit C protection group (D). TP or Vit C (100 mg/kg) was given orally to group C and D respectively, while the same volume of distilled water was given to the other two groups one time every day, continued for three days. Twelve hours after the final treatment, CCl4 (230 mg/kg) was given orally to group B ~ D. Thirty six hours later, all the mice were decapitated and liver homogenate were prepared for measuring MDA content. In FeSO4-cysteine induced lipid peroxidation in isolated human plasma, the inhibitory rate of TP (0.3 ~ 8.1 mg/L) was 30.7%, 32.0%, 46.9% and 59.7 %, and the inhibitory rate of Vit C (3 ~ 8.1 mg/L) was 8.3%, 41.4%, 47.7% and 52.7% for various dosages. In the CCl4 induced liver free radical injury system, the inhibitory rate of the same dosage of TP and Vit C was 45.2%, 42.8% respectively. TP (0.3 ~ 8.1 mg/L) and Vit C (9 ~ 81 mg/L) had inhibited lipid peroxidation induced by FeSO4-cysteine in isolated human plasma significantly, and the inhibitory effects of TP was superior to that of Vit C at the same dosages. The same dosage of TP and Vit C had remarkable inhibitory effects on the CCl4 induced liver free radical injury, but there was no significant difference between the two groups.

A high power Yb fiber laser and a distributed feedback (DFB) laser diode were used as DFG pump sources. This source generated mid-IR at 3 microns with a powers of ~2.5 microW and a spectral linewidth of less than 30 MHz. A frequency tuning range of 300 GHz (10 cm-1) was obtained by varying the current and temperature of the DFB laser diode. A high-resolution NH3 absorption Doppler-broadened spectrum at 3295.4 cm-1 (3.0345 microns) was obtained at a cell pressure of 27 Pa from which a detection sensitivity of 24 ppm m was estimated.

Wilson, NASA-TP-1998-208438), we have extracted nucleon-nucleon (N-N) cross-sections in the medium directly from experiment. The in-medium N-N cross-sections form the basic ingredients of several heavy-ion scattering approaches including the coupled-channel approach developed at the NASA Langley Research Center. Here, we investigate the ratio of real to imaginary part of the two-body scattering amplitude in the medium. These ratios are used in combination with the in-medium N-N cross-sections to calculate total proton-nucleus cross-sections. The agreement is excellent with the available experimental data. These cross-sections are needed for the radiation risk assessment of space missions. c2001 Elsevier Science B.V. All rights reserved. JF - Nuclear instruments & methods in physics research.

AN - 70668350; 11236924 AB - To investigate how cell-cycle delays in human peripheral lymphocytes affect the expression of complex chromosome damage in metaphase following high- and low-LET radiation exposure. Whole blood was irradiated in vitro with a low and a high dose of 1 GeV u(-1) iron particles, 400MeV u(-1) neon particles or y-rays. Lymphocytes were cultured and metaphase cells were collected at different time points after 48-84h in culture. Interphase chromosomes were prematurely condensed using calyculin-A, either 48 or 72 h after exposure to iron particles or gamma-rays. Cells in first division were analysed using a combination of FISH whole-chromosome painting and DAPI/ Hoechst 33258 harlequin staining. There was a delay in expression of chromosome damage in metaphase that was LET- and dose-dependant. This delay was mostly related to the late emergence of complex-type damage into metaphase. Yields of damage in PCC collected 48 h after irradiation with iron particles were similar to values obtained from cells undergoing mitosis after prolonged incubation. The yield of high-LET radiation-induced complex chromosome damage could be underestimated when analysing metaphase cells collected at one time point after irradiation. Chemically induced PCC is a more accurate technique since problems with complicated cell-cycle delays are avoided.

AN - 70667515; 11236923 AB - To investigate initial chromatid breaks in prematurely condensed G2 chromosomes following exposure to heavy ions of different LET. Exponentially growing human fibroblast cells AG1522 were irradiated with gamma-rays, energetic carbon (13 keV/ microm, 80 keV/microm), silicon (55 keV/microm) and iron (140 keV/microm, 185keV/microm, 440keV/microm) ions. Chromosomes were prematurely condensed using calyculin-A. Initial chromatid-type and isochromatid breaks in G2 cells were scored. The dose response curves for total chromatid breaks were linear regardless of radiation type. The relative biological effectiveness (RBE) showed a LET-dependent increase, peaking around 2.7 at 55-80keV/microm and decreasing at higher LET. The dose response curves for isochromatid-type breaks were linear for high-LET radiations, but linear-quadratic for gamma-rays and 13 keV/microm carbon ions. The RBE for the induction of isochromatid breaks obtained from linear components increased rapidly between 13keV/microm (about 7) and 80keV/microm carbon (about 71), and decreased gradually until 440 keV/microm iron ions (about 66). High-LET radiations are more effective at inducing isochromatid breaks, while low-LET radiations are more effective at inducing chromatid-type breaks. The densely ionizing track structures of heavy ions and the proximity of sister chromatids in G2 cells result in an increase in isochromatid breaks.

Before such missions can be initiated, much study remains to be done in technology development, mission operations, & human performance. While, eg, technology validation & operational experience could be gained in the context of lunar exploration missions, a NASA lunar program is seen as a competitor to a Mars mission rather than a step towards it. The recently characterized weak stability boundary in the Earth-Moon gravitational field may provide an operational approach to all types of planetary exploration, & infrastructure developed for a gateway to the solar system may be a programmatic solution for exploration that avoids the fractious bickering between Mars & Moon advocates.

These compositional data form the basis for integration and modeling with the reflectance spectra of these same soil fractions. This endeavor is aimed at deciphering the effects of space weathering of soils on airless bodies with quantification of the links between remotely sensed reflectance spectra and composition. A beneficial byproduct is an understanding of the complexities involved in the formation of lunar soil. Several significant findings have been documented in the study of the 2X), whereas the abundance of agglutinitic glass increases by only 10-15%. This is evidence for a large contribution from surface-correlated nanophase Fe (super 0) to the I (sub S) /FeO values, particularly in the <10 mu m size fraction. The surface nanophase Fe (super 0) is present largely as vapor-deposited patinas on the surfaces of almost every particle of the mature soils, and to a lesser degree for the immature soils (Keller et al., 1999a). It is reasoned that the vapor-deposited patinas may have far greater effects upon reflectance spectra of mare soils than the agglutinitic Fe (super 0) .

We find that liquid water would be stable within the Hellas and Argyre basin and over the northern lowlands equatorward of about 40 degrees . The location with the maximum period of stable conditions for liquid water is in the southeastern portion of Utopia Planitia, where 34% of the year liquid water would be stable if it were present. Locations of stability appear to correlate with the distribution of valley networks.

We suggest that a dynamic, large-scale circulation pattern brings processed dust and gas from the inner nebula back out into the region of cometesimal formation, extending possibly hundreds of astronomical units (AU) from the sun, and that the composition of comets is determined by a chemical reaction network closely coupled to the dynamic transport of dust and gas in the system. This scenario is supported by laboratory studies of Mg silicates and the astronomical data for comets and for protoplanetary disks associated with young stars, which demonstrate that annealing of nebular silicates must occur in conjunction with a large-scale circulation. Mass recycling of dust should have a significant effect on the chemical kinetics of the outer nebula by introducing reduced, gas-phase species produced in the higher temperature and pressure environment of the inner nebula, along with freshly processed grains with "clean" catalytic surfaces to the region of cometesimal formation. Because comets probably form throughout the lifetime of the Solar Nebula and processed (crystalline) grains are not immediately available for incorporation into the first generation of comets, an increasing fraction of dust incorporated into a growing comet should be crystalline olivine and this fraction can serve as a crude chronometer of the relative ages of comets. The formation and evolution of key organic and biogenic molecules in comets are potentially of great consequence to astrobiology.

[(1996) Science 273, 924-930] suggested that carbonate globules in the meteorite ALH84001 contained the fossil remains of Martian microbes. We have characterized a subpopulation of magnetite (Fe (sub 3) O (sub 4) ) crystals present in abundance within the Fe-rich rims of these carbonate globules. We find these Martian magnetites to be both chemically and physically identical to terrestrial, biogenically precipitated, intracellular magnetites produced by magnetotactic bacteria strain MV-1. Specifically, both magnetite populations are single-domain and chemically pure, and exhibit a unique crystal habit we describe as truncated hexa-octahedral. There are no known reports of inorganic processes to explain the observation of truncated hexa-octahedral magnetites in a terrestrial sample. In bacteria strain MV-1 their presence is therefore likely a product of Natural Selection. Unless there is an unknown and unexplained inorganic process on Mars that is conspicuously absent on the Earth and forms truncated hexa-octahedral magnetites, we suggest that these magnetite crystals in the Martian meteorite ALH84001 were likely produced by a biogenic process. As such, these crystals are interpreted as Martian magnetofossils and constitute evidence of the oldest life yet found.

The nu (sub CH) bands indicate that H (sub 2) O and CO (sub 2) , dissolved in the matrix of these minerals, converted to form H (sub 2) and chemically reduced C, which in turn formed C---H entities, probably through segregation into defects such as dislocations. Heating causes the C---H bonds to pyrolyze and the nu (sub CH) bands to disappear, but annealing at 70 degrees C causes them to reappear within a few days or weeks. Modeling dislocations in MgO suggests that the segregation of C can lead to C (sub x) chains, x = 4, with the terminal C atoms anchored to the MgO matrix by bonding to two O (super -) . Allowing H (sub 2) to react with such C (sub x) chains leads to [O (sub 2) C(CH (sub 2) ) (sub 2) CO (sub 2) ] or similar precipitates. It is suggested that such C (sub x) ---H (sub y) ---O (sub z) entities represent protomolecules from which derive the short-chain carboxylic and dicarboxylic and the medium-chain fatty acids that have been solvent-extracted from crushed MgO and olivine single crystals, respectively. Thus, it appears that the hard, dense matrix of igneous minerals represents a medium in which protomolecular units can be assembled. During weathering of rocks, the protomolecular units turn into complex organic molecules. These processes may have provided stereochemically constrained organics to the early Earth that were crucial to the emergence of life.

Other alpha -amino acids such as alanine, alpha -ABA, alpha -aminoisobutyric acid (AIB), and isovaline are present only in trace amounts (<200 ppb). Carbon isotopic measurements of beta -alanine and glycine and the presence of racemic (D/L nearly equal 1) alanine and beta -ABA in Orgueil suggest that these amino acids are extraterrestrial in origin. In comparison to the CM carbonaceous chondrites Murchison and Murray, the amino acid composition of the CIs is strikingly distinct, suggesting that these meteorites came from a different type of parent body, possibly an extinct comet, than did the CM carbonaceous chondrites.

New observations in two additional Martian meteorites, Nakhla (1.3 Ga old) and Shergotty (300-165 Ma old) indicate possible biogenic features. Features in the three Martian meteorites compare favorably with the accepted criteria for terrestrial microfossils and evidence for early life on the Earth. There is strong evidence for the presence of indigenous reduced carbon, biogenic magnetite, and the low-temperature formation of carbonate globules. The morphological similarities between terrestrial microfossils, biofilms, and the features found in the three Martian meteorites are intriguing but have not been conclusively proven. Every investigation must recognize the possibility of terrestrial contamination of the meteorites, whether or not the meteorites are Martian. The search for evidence of ancient life in Martian meteorites has emphasized the difficulties confronting the scientific community with the respect to the positive identification of evidence of past biogenic activity.

The results of the blended analysis differed dramatically from the CZCS representation: Global chlorophyll estimates increased 8-35% in the blended analysis depending upon season. Regional differences were even larger, up to 140% in the equatorial Indian Ocean in summer (during the southwest monsoon). Tropical Pacific chlorophyll values increased 25-41%. The results suggested that the CZCS generally underestimates chlorophyll. Regional and seasonal differences in the blended analysis were sufficiently large as to produce a different representation of global chlorophyll distributions than otherwise inferred from CZCS data alone. Analyses of primary production and biogeochemical cycles may be substantially impacted by these results. Copyright 2001 by the American Geophysical Union.

The lunar impact record indicates this was a time of heavy bombardment; the average lunar cratering rate between 4.15 and 3.8 Gyr was elevated approximately 150 times the modern value. Hence, heightened Ir and Pt abundances are possible in sediments from this time. However, the observed concentrations of Ir and Pt in the Akilia metasediments are extremely low. In most samples, Ir < 3 ppt and Pt < 20 ppt. In contrast, the average modern crustal abundances of Ir and Pt are approximately 50 ppt and approximately 2 ppb, respectively. The very low concentrations observed in the Akilia metasediments (cherts and banded iron formations) can be reconciled with the lunar record by quantifying the effects of sedimentation rate on the efficiency with which the extraterrestrial mass flux is sampled. The observations are explained if rapidly accumulating sediments sampled stochastic bombardment by an impactor population governed by a power law mass distribution, such that exogenous Ir and Pt are concentrated in rare horizons. The required sedimentation rates are geologically plausible. This explanation has two consequences. First, evidence of massive impact events may be rare in sediments older than 3.8 Gyr despite heavy bombardment. Second, conditions at the Earth's surface may have been conducive for extensive accumulation of sedimentary sequences and for microbial life during most of the period 4.15-3.8 Gyr. It is possible that the Earth's surface hosted microbial habitats during most of this time if microbes living in deep-sea or deep-crustal environments survived photic zone vaporizing impacts that would have occurred every approximately 30 Myr. Hence, evidence of life is expected even in the earliest sedimentary sequences. Copyright 2001 by the American Geophysical Union.

Recently we demonstrated that a simulated microgravity is conducive for maintaining long-term cultures of functional hepatocytes and promote 3D cell assembly. Using deoxyribonucleic acid (DNA) microarray technology, it is now possible to measure the levels of thousands of different messenger ribonucleic acids (mRNAs) in a single hybridization step. This technique is particularly powerful for comparing gene expression in the same tissue under different environmental conditions. The aim of this research was to analyze gene expression of hepatoblastoma cell line (HepG2) during early stage of 3D-cell assembly in simulated microgravity. For this, mRNA from HepG2 cultured in the RCCS was analyzed by deoxyribonucleic acid microarray. Analyses of HepG2 mRNA by using 6K glass DNA microarray revealed changes in expression of 95 genes (overexpression of 85 genes and downregulation of 10 genes). Our preliminary results indicated that simulated microgravity modifies the expression of several genes and that microarray technology may provide new understanding of the fundamental biological questions of how gravity affects the development and function of individual cells.

Natural liquid oil seepage is observed throughout the year in the Santa Barbara Channel off Coal Oil Point, and in Santa Monica Bay off Redondo Beach. The size and episodic nature of these phenomena, however, make them difficult to characterize by conventional shipboard sampling. Space-borne synthetic aperture radar (SAR) sensors are well suited to observing them since they provide frequent, synoptic, high-resolution, all- weather observations. The aim of this project is to initially quantify the frequency of occurrence, spatial extent, and dynamics of natural oil slicks and storm water runoff plumes off the coast of southern California using multi-sensor SAR data (e.g., Radarsat, ERS-1, ERS-2). Surfactants from these pollution hazards smooth surface waters, making them readily observable by SAR. These SAR observations will be complemented by other satellite (e.g., ocean color, AVHRR) and coincident field data (e.g., surface currents from HF coastal radar arrays and buoys, winds, precipitation, discharge) where possible. In particular, we hope to characterize the time-space response of these phenomena to variable oceanographic and atmospheric conditions. In this regard, the observation of natural oil slicks could provide important insights into the movement of accidental oil spills, including likely dispersal patterns. We expect this research will contribute to an improved understanding of pollution hazards in southern California coastal waters, and provide valuable information for coastal management.

It is difficult to ascribe this suppression to microgravity effects on immune cells in crew specimens, due to the complex physiological response to space flight and the resultant effect on in vitro immune performance. Use of isolated immune cells in true and modeled microgravity in immune performance tests, suggests a direct effect of microgravity on in vitro cellular function. Specifically, polyclonal activation of T-cells is severely suppressed in true and modeled microgravity. These recent findings suggest a potential suppression of oligoclonal antigen-specific lymphocyte activation in microgravity. We utilized rotating wall vessel (RWV) bioreactors as an analog of microgravity for cell cultures to analyze three models of antigen-specific activation. A mixed-lymphocyte reaction, as a model for a primary immune response, a tetanus toxoid response and a Borrelia burgdorferi response, as models of a secondary immune response, were all suppressed in the RWV bioreactor. Our findings confirm that the suppression of activation observed with polyclonal models also encompasses oligoclonal antigen-specific activation.

Coupled nonlinear periodic blade and fuselage equations are transformed to the modal space and solved simultaneously. The elastic line airframe model of the AH-1G helicopter is integrated into the elastic rotor finite element model. Analytical predictions of rotor control angles, blade loads, hub forces, and vibration are compared with AH-1G operation load survey test data. The blade loads predicted by the present analysis show generally fair agreement with the flight test data. Calculated 2 and 4 per revolution vertical vibration levels at the pilot seat show fair correlation with the flight test, but the predicted 2 per revolution lateral vibration level is higher than the measurement, particularly at high advance ratios. Modeling of pylon flexibility is essential in the two-bladed teetering rotor vibration analysis. Refined aerodynamics such as free wake and unsteady aerodynamics have an important role in the prediction of vibration.

Field measurements and airborne synthetic aperture radar (SAR) data were used to produce maps of forest cover type and above ground biomass. These forest attribute maps derived with remote sensing data, along with a conventional soils map, were used to identify the initial conditions for forest ecosystem model simulations. Using this information along with ecosystem model results enabled the development of predictive maps of forest development. The results obtained were consistent with observed forest conditions and expected successional trajectories. The study demonstrated that ecosystem models might be used in a spatial context when parametrized and used with georeferenced data sets.

Of 12 subjects, 8 were unable to complete the egress simulation with a G-suit inflation pressure of 1.5 psi. The purpose of this report was to compare CO sub(2) accumulation and egress walking time in the new Advanced Crew Escape Suit (ACES) with that in the LES. Four male subjects who previously were unable to complete the egress in the LES performed a simulated egress while wearing the ACES with the G-suit inflated to 1.5 psi. The egress simulation consisted of 6 min of seated rest, 2 min of standing, and 5 min of walking on a treadmill at 1.56 m times s super(-1) (3.5 mph) and 0% grade. The helmet visor was closed with the subjects receiving 100% oxygen throughout the simulation. Inspired CO sub(2) and walking time were measured. The rate of CO sub(2) accumulation was significantly less (ACES: 0.53 plus or minus 0.03, LES: 1.07 plus or minus 0.15% CO sub(2) times min super(-1); p = 0.05) and walk time was greater in the ACES (ACES: 5.0 plus or minus 0.0, LES: 2.7 plus or minus 0.2 min; p = 0.002). Changes in the design of the ACES from the LES resulted in a decreased rate of CO sub(2) accumulation and an improved egress walking time compared with the LES.

Although neither shimmy nor brake-induced vibrations are usually catastrophic, they can lead to accidents due to excessive wear and shortened life of gear parts and contribute to pilot and passenger discomfort. Recently, NASA has initiated an effort to increase the safety of air travel by reducing the number of accidents by a factor of five in 10 years. This safety initiative has spurred an increased interest in improving landing gear design to minimize shimmy and brake-induced vibration, which are still largely misunderstood phenomena. To increase the understanding of these problems, a literature survey was performed. The major focus of this paper is to summarize work documented from the last 10 years to highlight the latest efforts in solving these vibration problems. Older publications are included to show the longevity of the problem and the findings from earlier researchers. The literature survey revealed a variety of analyses, testing, modeling, and simulation of aircraft landing gear. Experimental validation and characterization of shimmy and brake-induced vibration of aircraft landing gear are also reported. An overview is presented of the problem documented in the references, together with a history of landing gear dynamic problems and solutions. Based on the assessment of this survey, recommendations of the most critically needed enhancements to the state of the art are given.

AN - 71333547; 12192685 AB - We report an integrated CMOS microluminometer for the detection of low-level bioluminescence in whole cell biosensing applications. This microluminometer is the microelectronic portion of the bioluminescent bioreporter integrated circuit (BBIC). This device uses the n-well/p-substrate junction of a standard bulk CMOS IC process to form the integrated photodetector. This photodetector uses a distributed electrode configuration that minimizes detector noise. Signal processing is accomplished with a current-to-frequency converter circuit that forms the causal portion of the matched filter for dc luminescence in wide-band white noise. Measurements show that luminescence can be detected from as few as 4 x 10(5) cells/ml. c2001 Elsevier Science B.V. All rights reserved. JF - Sensors and actuators.

That analysis, which is given in Goldstein & Leib (1993), required that the disturbance Reynolds number (i.e. the Reynolds number based on the disturbance velocity and length scale) be infinite while the present paper considers the more general case where this quantity can be finite. The results show how an initially linear perturbation of the upstream flow ultimately leads to a small-amplitude but nonlinear cross-flow far downstream from the leading edge. This flow can, under certain conditions, cause the streamwise velocity profiles to develop distinct shear layers in certain localized spanwise regions. These shear layers, which are remarkably similar to the ones that develop in Tollmien-Schlichting-wave transition (Kovasznay, Komoda & Vasudeva 1962), are highly inflectional and can therefore support the rapidly growing inviscid instabilities that are believed to break down into turbulent spots (Greenspan & Benney 1963, and, subsequently, many others). Numerical computations are carried out for input parameters which approximate the flow conditions of some recent experimental studies of the so-called Klebanoff-mode phenomenon. The results are used to explain some of the experimental observations, and, more importantly, to explain why the averaged quantities usually reported in these experiments do not correlate well with the turbulent-spot formation and therefore with the overall transition process.

AN - 85358652; pmid-11304014 AB - To examine the combined effects of gravitational and optical stimulation on perceived target elevation, we independently altered gravitational-inertial force and both the orientation and the structure of a background visual array. While being exposed to 1.0, 1.5, or 2.0 Gz in the human centrifuge at NASA Ames Research Center, observers attempted to set a target to the apparent horizon. The target was viewed against the far wall of a box that was pitched at various angles. The box was brightly illuminated, had only its interior edges dimly illuminated, or was kept dark. Observers lowered their target settings as Gz was increased; this effect was weakened when the box was illuminated. Also, when the box was visible, settings were displaced in the same direction as that in which the box was pitched. We attribute our results to the combined influence of otolith-oculomotor mechanisms that underlie the elevator illusion and visual-oculomotor mechanisms (optostatic responses) that underlie the perceptual effects of viewing pitched visual arrays.

The well-characterized external embryological development of the frog allows simple access to specific developmental stages by rapid visual inspection. We will conduct an insertional mutagenesis screen in Xenopus using a gene-trap vector containing a splice acceptor (SA) sequence followed by a marker gene, green fluorescent protein (GFP). Since the marker gene lacks a promoter, it can only be transcribed and translated if it integrates properly into an exon or intron of an endogenous gene. Expression of the bright GFP following insertional mutagenesis is visible in living embryos. In addition, since the trapped (and prospectively mutated) gene is always marked by GFP, one can easily distinguish between embryos carrying the mutation from ones that do not. We will use visual inspection to screen for tadpoles with insertions of the GFP- transgene into genes expressed during otic development. We propose the following specific aims: (1) We will use insertional mutagenesis to generate stable GFP- expressing lines of the true diploid, Xenopus tropicalis, carrying transgenes expressed in the otic regions. These stable lines will be used for studying the mutant phenotype generated by the insertion. (2) We will clone and characterize otic genes into which the GFP transgene has inserted. (3) We will characterize the development of the tissue in which the GFP-transgene is expressed using fluorescence video microscopy in live heterozygotic embryos or in fixed tissues using immunohistochemistry (both light and EM). Results of these investigations will provide essential knowledge of the specific genes involved in otic development as well as mutant lines that can be used for future studies of the specific function of these genes in acoustic or vestibular functions.

Over the past 10 years it has been demonstrated that ocular responses to linear motion are inversely proportional to viewing distance. This fact holds true regardless of whether the motion is due to translational motion of the visual scene, mediated by the ocular following reflex or due to translational head motion, mediated by the translational vestibulo-ocular reflex (TVOR). Both reflexes result in compensatory ocular responses which preserve the stability of the image on the retina. However, these studies were all conducted with the animal's head restrained, a condition that is not representative of normal experience. When the head is free to move, changes in the visual axis are associated with movements of both the eyes and the head (i.e., gaze). Studies using humans and non-human primates have demonstrated marked differences in the eye movements evoked during rotational motion when head-free and head-restrained results were compared. The proposed studies will examine the compensatory eye and head movements in 'head-free' primates exposed to brief vertical translations. The primates will be trained to fixate on a small target light positioned at various distances. Specific questions will address 1) how the effect of viewing distance is parsed between the command signals driving the eyes and the head during a compensatory gaze shift in the dark (translational gaze reflex, TGR), 2) whether anticompensatory inertial movements of the eyes, due to transient accelerations are dampened when the head is free to move, and 3) the latency of the vertical TGR. The Vertical Free-Fall Sled (VFS) produces a transient vertical linear acceleration characterized by an abrupt onset followed by a gradual deceleration. My previous work using the VFS, made use of this property to provide the first accurate measurement of the latency of the vertical TVOR in rhesus monkeys. In the proposed study, rapid onset of the stimulus will allow us to examine the compensatory visual and vestibular responses prior to the onset of visual feedback. Because an abrupt onset to the stimulus is achievable, it will be possible to characterize the temporal and spatial parsing of this signal - a necessary step towards understanding gaze control during normal behaviors such as locomotion where viewing distance is not static.

AN - 77077571; 11316343 AB - In a computational model of spreading depression (SD), ionic movement through a neuronal syncytium of cells connected by gap junctions is described electrodiffusively. Simulations predict that SD will not occur unless cells are allowed to expand in response to osmotic pressure gradients and K+ is allowed to move through gap junctions. SD waves of [K+]out approximately 25 to approximately 60 mM moving at approximately 2 to approximately 18 mm/min are predicted over the range of parametric values reported in gray matter, with extracellular space decreasing up to approximately 50%. Predicted waveform shape is qualitatively similar to laboratory reports. The delayed-rectifier, NMDA, BK, and Na+ currents are predicted to facilitate SD, while SK and A-type K+ currents and glial activity impede SD. These predictions are consonant with recent findings that gap junction poisons block SD and support the theories that cytosolic diffusion via gap junctions and osmotic forces are important mechanisms underlying SD.

AN - 72388239; 11780618 AB - The approaches generally adopted for planning radiation protection in ground-based facilities cannot be applied straightforward for astronaut protection in space. Indeed in such extreme conditions, modelling methods and shielding design must be based on a detailed mechanistic knowledge of the peculiar astronauts irradiation conditions. Great help can derive from mechanistic modelling, generally aimed to better understand the intermediate steps leading from the initial energy depositions to different biological endpoints, up to organ and organism level. In the present work, criteria will be illustrated for using mechanistic approaches in developing practical tools for astronauts radioprotection, once the external field and the interaction cross sections with the spacecraft walls are known; particular attention will be given to the treatment of mixed fields.

AN - 72387100; 11780615 AB - The influence of simulated microgravity weightlessness on the outcome of radiation-induced chromosomal aberrations was investigated using the clinostat as a tool to simulate weightlessness conditions. Treatments were performed in the G0 phase of human lymphocytes with 1.5 Gy of X-rays alone or in combination with the DNA synthesis inhibitor of 1-beta-D-arabinofuranosylcytosine (ara-C) to check also for possible specific radiation-induced DNA repair processes impairment (excision repair caused by base damage) under microgravity conditions. The results obtained, which confirmed previous findings, showed significantly higher increases of aberrant cells and hence total number of aberrations compared to the parallel treatments performed 'on ground'. For what concern ara-C its contribution in terms of potentiation in the induction of aberrant cells was equivalent in absolute terms under simulated microgravity conditions and 'on ground' indicating that excision repair caused by base damage and inhibited by ara-C is not affected by simulated microgravity. A possible explanation for this outcome could quote two major factors: i) Enhanced probability that under simulated microgravity conditions the reactive DSB are spatially brought together to better interact, hence increasing the probability of mis-rejoining. ii) Alternatively chromatin structure could be modified under simulated microgravity conditions generating different quality and quantities of DNA lesions compared to treatments performed 'on ground'.

AN - 72386063; 11780619 AB - Radiobiology with charged particles is being carried out in Italy since several decades, starting with the experiments with protons in Milan. Later, also other groups entered the field, such as those in Naples, in Legnaro (LNL) and in Rome. In the last 10-15 years the activities in the field began to grow in a significant way. This happened in concomitance with the involvement of various researchers and Institutions in European and international projects devoted to radiation protection aspects, such as those aimed at elucidating and modelling radiation action mechanisms (EC/EU) and those aimed at radiation protection in space (NASA). A special role has been played since then by the Laboratori Nazionali di Legnaro of the INFN, where a radiobiology facility for low energy light ions was set up and operated in 1985. A formidable stimulus for charged-particle radiobiology was more recently given by the onset of plans for developing hadrontherapy Centres in Italy. The TERA Foundation first, and than the TOP Project at the Istituto Superiore di Sanità, at the same time favoured the spreading in Italy of radiobiology research with charged particles and encouraged co-operation among various groups. The Italian radiobiology community, though relatively small, developed a number of valuable activities with charged particles, mostly at the cellular and molecular levels, that span from mechanisms of radiation action to radiation protection in space and to therapy with charged hadrons. In this article, due to space limitations, we have just been able to list the present activities and to briefly review some research that forms a common background for the various areas. This includes the work on Chinese hamster V79 cells irradiated with light ions at LNL, that provided extensive data on the relationships between radiation quality, molecular damage and cellular effects, and the related work aimed at possible interpretation by mechanistic models. It appears that the multiplicity of objectives does not represent a factor of weakness for the relatively small Italian radiobiology community. Synergistic effects have been found because the basic radiobiology is the same for different areas such as radiation protection and hadrontherapy, and because the expertise and the methods developed for a given purpose may find useful applications in others. Though it is difficult to forecast the future development in Italy of the various areas that will take advantage of charged-particle radiobiology, it is expected that hadrontherapy and space radiation protection together, independently of their relative weight, will be important driving forces for the future development of the field in our Country.

AN - 72385314; 11776989 AB - The radiation absorbed by astronauts during interplanetary flights is mainly due to cosmic rays of solar origin (SCR). In the most powerful solar flares the dose absorbed in few hours can exceed that cumulated in one year of exposition to the galactic component of cosmic rays (GCR). At energies above the minimum one needed to cross the walls of the spaceship there are extrapolations and guesses, but no data, on the angular distribution of SCR's, an information that is necessary for establishing whatever defence strategy. It was therefore proposed of sending to Mars a measurement device, that should continuously collect data during the travel, and possibly also in the orbit around Mars and on the Mars surface. The device should identify the particle and privilege the completeness in the measurement of its parameters. In fact the high energy electrons travel at speed of the light and could be used in the and future dangerous proton component. Also the much less abundant but individually more dangerous ions should be identified. The device should indeed include a magnetic spectrometer and a high granularity range telescope, and a good time of flight measurement. ASI is supporting an assessment study of a possible mission of such a device on board of the 2005 probe to Mars. A parallel technical study is also in progress to define the workable techniques and the possible configurations of a system of magnetic lenses for protecting the crew of a spaceship.

AN - 72385229; 11780617 AB - A research program in space radiobiology is described in this report. The program is focused on the effect of the shielding on the biological effects of heavy ions. Both experiments and models are included in the program. Experiments aim to determine genetic effects of heavy ions with or without shielding. Mathematical models, based on Monte Carlo codes, will be used to interpret the biological results. The final goal is to get a feasible model able to predict the radiation-induced biological damage in space, given the free-space radiation field and the space vessel shielding. The grant is supported by the Italian Space Agency (ASI), and involves Italian radiation biophysics groups (Universities of Milan and Naples, National Institute of Health in Rome), in collaboration with NASA (USA), NIRS (Japan), CERN (Switzerland), Brookhaven National Laboratories (USA), and TERA (Italy).

AN - 72384888; 11780614 AB - Aim of this investigation is the study of the modifications and the DNA damage occurring in thyroid cells exposed to radiation. The FRTL-5 rat thyroid cell strain has been chosen for this study. Objects of this research are both Ionizing radiation, of fundamental interest for space missions, and the UV radiation, (also mutagen and frequent cause of several cancer forms). The present study of UV radiation represents a preliminarily tool to investigate the biological radiation damage. FRTL-5 cells have been irradiated with doses of UV-C (254 nm wavelength) ranging from 15 to 80 Joule/m2. The DNA damage has been analyzed with the 'DNA ladder by gel electrophoresis' technique. DNA has been extracted at 24 and 48 hours from irradiation. At 24h the apoptotic process is not detectable. At 48 h from irradiation, cells show the characteristic signs of apoptosis. The lower dose to which the apoptotic process is detectable, corresponds to 20 Joule/m2. At the higher doses a bigger percentage of cells undergoes apoptosis. These data confirms that the FRTL-5 biological system is particularly suitable for further studies on the biological mechanisms of radiation damage.

AN - 72383719; 11776982 AB - The purpose of this study is to determine the kinetics of chromatid break rejoining following exposure to radiations of different quality. Exponentially growing human fibroblast cells AG1522 were irradiated with gamma-rays, energetic carbon (290 MeV/u), silicon (490 MeV/u) and iron (200 MeV/u, 600 MeV/u). Chromosomes were prematurely condensed using calyculin A. Prematurely condensed chromosomes were collected after several post-irradiation incubation times, ranging from 5 to 600 minutes, and the number of chromatid breaks and exchanges in G2 cells were scored. The relative biological effectiveness (RBE) for initial chromatid breaks per unit dose showed LET dependency having a peak at 55 keV/micrometers silicon (2.4) or 80 keV/micrometers carbon particles (2.4) and then decreased with increasing LET. The kinetics of chromatid break rejoining following low- or high-LET irradiation consisted of two exponential components. Chromatid breaks decreased rapidly after exposure, and then continued to decrease at a slower rate. The rejoining kinetics was similar for exposure to each type of radiation, although the rate of unrejoined breaks was higher for high-LET radiation. Chromatid exchanges were also formed quickly.

AN - 72383491; 11776984 AB - The comet assay is a sensitive and rapid method for DNA strand break detection in individual cells. The principle of break detection, using either the alkaline or neutral version of the assay, makes it a good technique for studying both double and single strand DNA breaks. Furthermore, the possibility of following DNA damage at different time moments also makes it possible to investigate the cell repair mechanisms. This explains why in the last few years there has been a tremendous increase in the number of laboratories which started to use this technique. The technique was first created for lymphocyte cells and later on has been used on many other cell types, growing both in suspension and adherent. To date, no one has applied this technique on normal differentiated endocrine cells, such as FRTL5 cells (Fisher Rat Thyroid Cells). The aim of this study has been to standardize the alkaline version of the Comet Assay technique on FRTL5 cells by studying the kinetics of DNA-damage and DNA-repair after different doses of UV-C (254 nm). FRTL-5 cells not only resulted very sensitive to UV-C (p<0.05 at 5 J/m2), but were also able to repair most of their DNA damage very rapidly (within one hour) as shown by a significant exponential regression in comet length. Finally, the successful measurement of biomarkers of UV-C on thyroid cells established the comet assay as a valuable tool in measurement of DNA damage and repair. Any radiation, or other damaging agents, interacting with living organisms could cause DNA damages which, depending upon dosages and kinetics of exposure, may or may not be completely repaired.

AN - 72383456; 11776983 AB - If radiosensitivity is altered in a microgravity environment, it will affect the accuracy of assessing astronauts' risk from exposure to space radiation. To investigate the effects of space flight on radiosensitivity, we exposed a crewmember's blood to gamma rays at doses ranging from 0 to 3 Gy and analyzed chromosome aberrations in mitotic lymphocytes. The blood samples were collected 10 days prior to an 8-day Shuttle mission, the day the flight returned, and 14 days after the flight. After exposure, lymphocytes were stimulated to grow in media containing phytohaemagglutinin (PHA) and mitotic cells were harvested for chromosome analysis using a fluorescence in situ hybridization (FISH) with whole chromosome specific probes. The dose response of total exchanges showed no changes in the radiosensitivity after the mission.

AN - 72383011; 11776986 AB - The goal of this study was to assess whether charged particle radiations of importance to spaceflight elicit genomic instability in human TK6 lymphoblasts. The incidence of genomic instability in TK6 cells was assessed ~21 days after exposure to 2, 4, or 6 Fe ions (1 GeV/amu, LET= 146 keV/micrometers). Three indices of instability were used: intraclonal karyotypic heterogeneity, mutation rate analysis at the thymidine kinase (TK1) locus, and re-cloning efficiency. Fifteen of sixty clones demonstrated karyotypic heterogeneity. Five clones had multiple indicators of karyotypic change. One clone was markedly hypomutable and polyploid. Six clones were hypomutable, while 21 clones were mutators. Of these, seven were karyotypically unstable. Six clones had low re-cloning efficiencies, one of which was a mutator. All had normal karyotypes. In summary, many clones that survived exposure to a low fluence of Fe ions manifested one or more forms of genomic instability that may hasten the development of neoplasia through deletion or by recombination.

AN - 72382702; 11776987 AB - In this paper we present some preliminary results on alteration of gene expression caused by radiation on human endometrial cells. To this purpose, we have studied the modulation of the expression of the bcl-2 gene family in two cell lines following irradiations with low energy protons and gamma-rays from a 60Co. The two epithelial cell strains, namely AN3Ca and HEC1B cells, both obtained from human neoplastic endometrial tissues, grow in culture and continue to maintain some differentiated functions typical of the original tissue. Indeed, these cells, that can be considered as representative of different stages of cellular transformation of endometrium. Because their epithelial nature and rapid growth, the expression of genes related to the maintenance of the cellular homeostasis (correction of omeostasis), as the pro and anti-apoptotic ones, is expected to be susceptible to changes in environment, including radiation. The effects have been evaluated in terms of both cell survival and changes in the expression of pro- and anti apoptotic proteins. Even though the data reported above can not be considered complete and/or definitive, nevertheless, in whole, they confirm that these cells may constitute a suitable model system to study, at molecular level, the effects of cosmic radiation on endometrium. Further observation, ensuing from these preliminary data, is that endometrial cells present different sensitivity to radiation in regard to its 'quality' and 'dosage', in accord to the original stage of differentiation.

AN - 72382671; 11776985 AB - Protons represent the major type of charged particle radiation in spaceflight environments. The purpose of this study was to assess mutations arising in human lymphoid cells exposed to protons. Mutations were quantitated at the thymidine kinase (TK1) locus in cell lines derived from the same donor: TK6 cells (wt TP53) and WTK1 cells (mutant TP53). WTK1 cells were much more susceptible to mutagenesis following proton exposure than TK6 cells. Intragenic deletions were observed among early-arising TK1 mutants in TK6 cells, but not in WTK1 cells where all of the mutants arose by LOH. Deletion was the predominant mode of LOH in TK6 cells, while allelic recombination was the major mode of LOH in WTK1 cells. Deletions were of variable lengths, from <1 cM to 64 cM, while mutations that arose by allelic recombination often extended to the telomere. In summary, proton exposures elicited many types of mutations at an autosomal locus in human cells. Most involved large scale loss of genetic information, either through deletion or by recombination.

AN - 72382109; 11770545 AB - In order for humans and electronics to fully and safely operate in the space environment, codes like HZETRN (High Charge and Energy Transport) must be included in any designer's toolbox for design evaluation with respect to radiation damage. Currently, spacecraft designers do not have easy access to accurate radiation codes like HZETRN to evaluate their design for radiation effects on humans and electronics. Today, the World Wide Web is sophisticated enough to support the entire HZETRN code and all of the associated pre and post processing tools. This package is called SIREST (Space Ionizing Radiation Effects and Shielding Tools). There are many advantages to SIREST. The most important advantage is the instant update capability of the web. Another major advantage is the modularity that the web imposes on the code. Right now, the major disadvantage of SIREST will be its modularity inside the designer's system. This mostly comes from the fact that a consistent interface between the designer and the computer system to evaluate the design is incomplete. This, however, is to be solved in the Intelligent Synthesis Environment (ISE) program currently being funded by NASA.

AN - 72381933; 11770525 AB - A reference facility for the intercomparison of active and passive detectors in high-energy neutron fields is available at CERN since 1993. A positive charged hadron beam (a mixture of protons and pions) with momentum of 120 GeV/c hits a copper target, 50 cm thick and 7 cm in diameter. The secondary particles produced in the interaction are filtered by a shielding of either 80 cm of concrete or 40 cm of iron. Behind the iron shielding, the resulting neutron spectrum has a maximum at about 1 MeV, with an additional high-energy component. Behind the concrete shielding, the neutron spectrum has a pronounced maximum at about 70 MeV and resembles the high-energy component of the radiation field created by cosmic rays at commercial flight altitudes. The facility is used for a variety of investigations with active and passive neutron dosimeters. Its use for measurements related to the space programme is discussed.

AN - 72381757; 11771541 AB - Solid State Nuclear Track Detectors (SSNTD's) are used in a wide range of applications such as Geological Dating, Environmental Sciences (radon), life Sciences (Radiobiology, Dosimetry...), as well as Nuclear and Astro-Physics. In order to be observable under a microscope, the nanometric latent damaged trails due to the slowing down of charged particles into the SSNTD have to be specifically etched. In our laboratory, we are studying this chemical action and propose models that enable simulations to be performed. In the literature, the basic model uses two distinct etch-rates that are considered constant, VB; the Bulk and VT the Track etch-rate. A little bit more sophisticated and realistic, a model with a variable track etch-rate was established, taking into account the variation of energy deposition along the particle's trajectory. Up to now, the known methods used for determining the response function of CR-39 are very time consuming and strenuous. The method we present here is based on the use of the confocal microscope, which provides three-dimensional track images. The obtained set of 3-D co-ordinates can be treated mathematically, giving, in the framework of the two etch-velocity model, the response function. With this new approach, tracks are analysed one by one; response functions are obtained for each track and can be compared to fundamental characteristics of the charged Particle-Matter interactions. Moreover, the method we propose is applied semi-automatically and could easily be automated in the near future.

AN - 72381686; 11770540 AB - Future deep space mission and International Space Station exposures will be dominated by the high-charge and -energy (HZE) ions of the Galactic Cosmic Rays (GCR). A few mammalian systems have been extensively tested over a broad range of ion types and energies. For example, C3H10T1/2 cells, V79 cells, and Harderian gland tumors have been described by various track-structure dependent response models. The attenuation of GCR induced biological effects depends strongly on the biological endpoint, response model used, and material composition. Optimization of space shielding is then driven by the nature of the response model and the transmission characteristics of the given material.

AN - 72381644; 11776988 AB - Cell adhesion molecules (CAMs) are proteins which anchor cells to each other and to the extracellular matrix (ECM), but whose functions also include signal transduction, differentiation, and apoptosis. We are testing a hypothesis that particle radiations modulate CAM expression and this contributes to radiation-induced lens opacification. We observed dose-dependent changes in the expression of beta 1-integrin and ICAM-1 in exponentially-growing and confluent cells of a differentiating human lens epithelial cell model after exposure to particle beams. Human lens epithelial (HLE) cells, less than 10 passages after their initial culture from fetal tissue, were grown on bovine corneal endothelial cell-derived ECM in medium containing 15% fetal bovine serum and supplemented with 5 ng/ml basic fibroblast growth factor (FGF-2). Multiple cell populations at three different stages of differentiation were prepared for experiment: cells in exponential growth, and cells at 5 and 10 days post-confluence. The differentiation status of cells was characterized morphologically by digital image analysis, and biochemically by Western blotting using lens epithelial and fiber cell-specific markers. Cultures were irradiated with single doses (4, 8 or 12 Gy) of 55 MeV protons and, along with unirradiated control samples, were fixed using -20 degrees C methanol at 6 hours after exposure. Replicate experiments and similar experiments with helium ions are in progress. The intracellular localization of beta 1-integrin and ICAM-1 was detected by immunofluorescence using monoclonal antibodies specific for each CAM. Cells known to express each CAM were also processed as positive controls. Both exponentially-growing and confluent, differentiating cells demonstrated a dramatic proton-dose-dependent modulation (upregulation for exponential cells, downregulation for confluent cells) and a change in the intracellular distribution of the beta 1-integrin, compared to unirradiated controls. In contrast, there was a dose-dependent increase in ICAM-1 immunofluorescence in confluent, but not exponentially-growing cells. These results suggest that proton irradiation downregulates beta 1-integrin and upregulates ICAM-1, potentially contributing to cell death or to aberrant differentiation via modulation of anchorage and/or signal transduction functions. Quantification of the expression levels of the CAMs by Western analysis is in progress.

AN - 72381607; 11770536 AB - The particles and energies commonly used for hadron therapy overlap the low end of the charge and energy range of greatest interest for space radiation applications, Z=1-26 and approximately 100-1000 MeV/nucleon. It has been known for some time that the nuclear interactions of the incident ions must be taken into account both in treatment planning and in understanding and addressing the effects of galactic cosmic ray ions on humans in space. Until relatively recently, most of the studies of nuclear fragmentation and transport in matter were driven by the interests of the nuclear physics and later, the hadron therapy communities. However, the experimental and theoretical methods and the accelerator facilities developed for use in heavy ion nuclear physics are directly applicable to radiotherapy and space radiation studies. I will briefly review relevant data taken recently at various accelerators, and discuss the implications of the measurements for radiotherapy, radiobiology and space radiation research.

AN - 72381502; 11776980 AB - This study was aimed at investigating the radiation induced DNA fragmentation pattern as a function of cellular differentiation and radiation quality. DNA double strand breaks (DSB) induced by gamma-rays were analyzed in K562 human proerythroblasts before (AP cells) and after (D cells) differentiation induction while DNA DSB induced by 125 keV/micrometers N-ions have been studied in AP cells. Pulsed-Field Gel Electrophoresis (PFGE) of cellular DNA was used to determine the DSB yield by analysis of the Fraction of Activity Released (FAR) and of the fragmentation pattern in a specific size range (5.7-0.225 Mbp). The results so far obtained show that the DSB induction by gamma-rays is different if evaluated with the FAR or with the fragmentation analysis. The DSB yield obtained with the former method is about 1.4 times higher in AP respect to D cells while the latter method indicates that more fragments are produced in D cells. Comparison between gamma-rays and N-ions in AP cells shows that no significant differences are detected by the FAR analysis; otherwise fragmentation analysis demonstrates a higher effectiveness of nitrogen ions.

AN - 72380998; 11770523 AB - The US Lab module of the International Space Station (ISS) is a primary working area where the crewmembers are expected to spend majority of their time. Because of the directionality of radiation fields caused by the Earth shadow, trapped radiation pitch angle distribution, and inherent variations in the ISS shielding, a model is needed to account for these local variations in the radiation distribution. We present the calculated radiation dose (rem/yr) values for over 3,000 different points in the working area of the Lab module and estimated radiation dose values for over 25,000 different points in the human body for a given ambient radiation environment. These estimated radiation dose values are presented in a three dimensional animated interactive visualization format. Such interactive animated visualization of the radiation distribution can be generated in near real-time to track changes in the radiation environment during the orbit precession of the ISS.

AN - 72380857; 11771552 AB - Astronauts' radiation exposure limits are based on experimental and epidemiological data obtained on Earth. It is assumed that radiation sensitivity remains the same in the extraterrestrial space. However, human radiosensitivity is dependent upon the response of the hematopoietic tissue to the radiation insult. It is well known that the immune system is affected by microgravity. We have developed a mathematical model of radiation-induced myelopoiesis which includes the effect of microgravity on bone marrow kinetics. It is assumed that cellular radiosensitivity is not modified by the space environment, but repopulation rates of stem and stromal cells are reduced as a function of time in weightlessness. A realistic model of the space radiation environment, including the HZE component, is used to simulate the radiation damage. A dedicated computer code was written and applied to solar particle events and to the mission to Mars. The results suggest that altered myelopoiesis and lymphopoiesis in microgravity might increase human radiosensitivity in space.

AN - 72380833; 11770542 AB - To develop materials for shielding astronauts from the hazards of GCR, natural Martian surface materials are considered for their potential as radiation shielding for manned Mars missions. The modified radiation fluences behind various kinds of Martian rocks and regolith are determined by solving the Boltzmann equation using NASA Langley's HZETRN code along with the 1977 Solar Minimum galactic cosmic ray environmental model. To develop structural shielding composite materials for Martian surface habitats, theoretical predictions of the shielding properties of Martian regolith/polyimide composites has been computed to assess their shielding effectiveness. Adding high-performance polymer binders to Martian regolith to enhance structural properties also enhances the shielding properties of these composites because of the added hydrogenous constituents. Heavy ion beam testing of regolith simulant/polyimide composites is planned to validate this prediction. Characterization and proton beam tests are performed to measure structural properties and to compare the shielding effects on microelectronic devices, respectively.

AN - 72380079; 11771539 AB - The 3MV HVEC TTT-3 Tandem accelerator at the University of Naples, already used for radiobiological studies with protons and alpha particles, was set up for irradiation of biological samples with low energy carbon, boron, and beryllium beams. Radiobiological characterisation and study of these ion beams is essential in hadrontherapy (correction of hadrotherapy) to understand, for example, the possible biological effect of the target fragmentation products. Furthermore in space radiation biology we need to know the biological effects of heavy ions, a component of cosmic radiation that can contribute to the radiobiological risk when long sojourns in space are concerned. V79 Chinese hamster cells were irradiated with the different ions and the resulting cell inactivation data are reported.

AN - 72380055; 11776261 AB - Chromosome aberrations are routinely analysed in metaphase cells at one sampling time post-irradiation. Yet, accumulating evidence shows that radiation-induced cycle perturbations and mitotic delay influence the yield of aberrations detectable in mitosis. In extended time-course studies a drastic increase in the number of aberrations with sampling time has been observed after particle irradiation, while after the exposure to sparsely ionizing radiation a less pronounced effect has been found. This difference in the time-course of chromosomal damage is particularly important for the determination of accurate RBE values. As will be discussed, meaningful RBE values for particles can only be obtained, if cells are analysed at multiple sampling times and the complete time-course of aberrations is considered. Otherwise, particle-induced damage will be over- or underestimated. Moreover, depending on the cell system chosen for the analysis, factors like the loss of damaged cells due to apoptosis or a permanent cell cycle arrest complicate the determination of accurate RBE values based on chromosome data.

AN - 72379920; 11776277 AB - Preliminary measurements on the production of single- and double-strand breaks in SV40 and phi X174 plasmid DNA by various heavy ions in radioprotective Tris buffer are presented. The dependence of the recorded yields on the LET of the incoming ions is discussed and shown to be comprehensible within the framework of a model based on the X-ray sensitivity of the exposed DNA and the local dose distribution inside the heavy ion track. The question of the influence of the chemical environment is addressed by comparing the measured cross sections to data recorded previously in more radiosensitive TE buffer. The results indicate that also for systems with high scavenging capacity RBE values larger than unity can be achieved with maximum values in the LET range 100-1000 keV micrometers-1.

AN - 72379838; 11770526 AB - The Proton Irradiation Facility (PIF) has been designed and constructed, in cooperation between Paul Scherrer Institute (PSI) and European Space Agency (ESA), for terrestrial proton testing of components and materials for spacecraft. Emphasis has been given to generating realistic proton spectra encountered by space-flights at any potential orbit. The facility, designed in a user-friendly manner, can be readily adapted to the individual requirements of experimenters. It is available for general use serving also in testing of radiation monitors and for proton experiments in different scientific disciplines. The Radiation Environment Monitor REM has been developed for measurements of the spacecraft radiation conditions. Two instruments were launched into space, one into a Geo-stationary Transfer Orbit on board of the STRV-1b satellite and one into a Low Earth Orbit on the Russian MIR station. The next generation of monitors (SREMs--Standard REMs) is currently under development in partnership of ESA, PSI and Contraves-Space. They will operate both as minimum intrusive monitors, which provide radiation housekeeping data and alert the spacecraft when the radiation level crosses allowed limits and as small scientific devices measuring particle spectra and fluxes. Future missions as e.g. INTEGRAL, STRV-1c and PROBA will be equipped with new SREMs. JF - Physica medica : PM : an international journal devoted to the applications of physics to medicine and biology : official journal of the Italian Association of Biomedical Physics (AIFB) AU - Hajdas, W AU - Zehnder, A AU - Adams, L AU - Buehler, P AU - Harboe-Sorensen, R AU - Daum, M AU - Nickson, R AU - Daly, E AU - Nieminen, P AD - Paul Scherrer Institute, Villigen, Switzerland.

AN - 72379829; 11776262 AB - Clustered DNA damages--here defined as two or more lesions (strand breaks, oxidized purines, oxidized pyrimidines or abasic sites) within a few helical turns--have been postulated as difficult to repair accurately, and thus highly significant biological lesions. Further, attempted repair of clusters may produce double strand breaks (DSBs). However, until recently, there was no way to measure ionizing radiation-induced clustered damages, except DSB. We recently described an approach for measuring classes of clustered damages (oxidized purine clusters, oxidized pyrimidine clusters, abasic clusters, along with DSB). We showed that ionizing radiation (gamma rays and Fe ions, 1 GeV/amu) does induce such clusters in genomic DNA in solution and in human cells. These studies also showed that each damage cluster results from one radiation hit (and its track), thus indicating that they can be induced by very low doses of radiation, i.e. two independent hits are not required for cluster induction. Further, among all complex damages, double strand breaks comprise--at most-- ~20%, with the other clustered damages being at least 80%.

AN - 72379805; 11770543 AB - During the 1960's and into the early 1970's, investigations were conducted related to the feasibility of using active radiation shielding methods, such as afforded by electromagnetic fields, as alternatives to passive, bulk material shielding to attenuate space radiations. These active concepts fall into four categories: (1) electrostatic fields; (2) plasma shields; (3) confined magnetic fields; and (4) unconfined magnetic fields. In nearly all of these investigations, consideration was given only to shielding against protons or electrons, or both. During the 1980's and 1990's there were additional studies related to proton shielding and some new studies regarding the efficacy of using active methods to shield from the high energy heavy ion (HZE particle) component of the galactic cosmic ray spectrum. In this overview, each concept category is reviewed and its applicability and limitations for the various types of space radiations are described. Recommendations for future research on this topic are made.

AN - 72379716; 11770539 AB - NASA has established and supports a specialized center for research and training (NSCORT) to specifically address the potential deleterious effects of HZE particles on human health. The NSCORT in radiation health is a joint effort between Lawrence Berkeley National Laboratory (LBNL) and Colorado State University (CSU). The overall scope of research encompasses a broad range of subjects from microdosimetric studies to cellular and tissue responses to initial damage produced by highly energetic protons and heavy charged particles of the type found in galactic cosmic rays (GCR) spectrum. The objectives of the microdosimetry studies are to determine the response of Tissue Equivalent Proportional Counter (TEPC) to cosmic rays using ground based accelerators. This includes evaluation of energy loss due to the escape of high-energy delta rays and increased energy deposition due to the enhanced delta ray production in the wall of the detector. In this report major results are presented for 56Fe at 1000, 740, 600 and 400 MeV/nucleon. An assessment of DNA repair and early development of related chromosomal changes is extremely important to our overall understanding of enhanced biological effectiveness of high LET particle radiation. Results are presented with respect to the fidelity of the rejoining of double strand breaks and the implications of misrejoining. The relationship between molecular and cytogenetic measurements is presented by studying damage processing in highly heterochromatic supernumerary (correction of sypernumerary) X chromosomes and the active X-chromosome. One of the important consequences of cell's inability to handle DNA damage can be evaluated through mutation studies. Part of our goal is the assessment of potential radioprotectors to reduce the mutation yield following HZE exposures, and some promising results are presented on one compound. A second goal is the integration of DNA repair and mutation studies. Results are presented on a direct comparison of initial double strand breaks induction, the time course and fidelity of double strand break rejoining, cell killing and mutation induction in the same human model system. In order to understand the carcinogenic potential of protons and HZE particles, the role of damaged microenvironment in this process must be understood. In this project it has been postulated that radiation affects the microenvironment, which then modifies cell interactions in a manner conducive to neoplastic progression. Both TGF-beta and FGF-2 are important components of microenvironment. A recent result on the assessment of the role of FGF-2 and its cross-talk with TGF-beta as a function of radiation quality is presented. Theoretical modeling has so far played a central role in analyzing and integrating experimental data on repair and mutation studies and predicting new phenomena. The integrated NSCORT program also provides a broad training experience for students and postdoctoral fellows in space radiation health.

AN - 72379603; 11770522 AB - An example of pragmatic approach for predicting mixed field effects is presented. The method was initially applied adopting the following, commonly used, assumptions: a) radiation risk (typically cancer) is correlated with chromosome aberration induction; b) radiation-induced chromosome-exchange yield can be well described by a linear-quadratic dependence on particle fluences (mostly linear with high-LET radiation), with parameters depending on particle types and energies. Information on monochromatic field radiobiological effects was integrated in a condensed-history Monte Carlo transport code (FLUKA), able to simulate nuclear interactions. The integrated code provides the chromosome aberration yield (and thus an estimation of radiation risk) in each voxel of any irradiated volume, given any external mixed-field irradiation; in the present work, the method was tested for neutron irradiation of a water phantom.

AN - 72379524; 11770546 AB - Radiation is a primary concern in the planning of a manned mission to Mars. Recent studies using NASA Langley Research Center's HZETRN space radiation transport code show that the low energy neutron fluence on the Martian surface is larger than previously expected. The upper atmosphere of Mars is exposed to a background radiation field made up of a large number of protons during a solar particle event and mixture of light and heavy ions caused by galactic cosmic rays at other times. In either case, these charged ions interact with the carbon and oxygen atoms of the Martian atmosphere through ionization and nuclear collisions producing secondary ions and neutrons which then interact with the atmospheric atoms in a similar manner. In the past, only these downward moving particles have been counted in evaluating the neutron energy spectrum on the surface. Recent enhancements in the HZETRN code allow for the additional evaluation of those neutrons created within the Martian regolith through the same types of nuclear reactions, which rise to the surface. New calculations using this improved HZETRN code show that these upward moving neutrons contribute significantly to the overall neutron spectrum for energies less than 10 MeV.

AN - 72379402; 11770530 AB - Radiological assessment of the many cosmic ion species of widely distributed energies requires the use of theoretical transport models to accurately describe diverse physical processes related to nuclear reactions in spacecraft structures, planetary atmospheres and surfaces, and tissues. Heavy-ion transport models that were designed to characterize shielded radiation fields have been validated through comparison with data from thick-target irradiation experiments at particle accelerators. With the RTD Mission comes a unique opportunity to validate existing radiation transport models and guide the development of tools for shield design. For the first time, transport properties will be measured in free-space to characterize the shielding effectiveness of materials that are likely to be aboard interplanetary space missions. Target materials composed of aluminum, advanced composite spacecraft structure and other shielding materials, helium (a propellant) and tissue equivalent matrices will be evaluated. Large solid state detectors will provide kinetic energy and charge identification for incident heavy-ions and for secondary ions created in the target material. Transport calculations using the HZETRN model suggest that 8 g cm -2 thick targets would be adequate to evaluate the shielding effectiveness during solar minimum activity conditions for a period of 30 days or more.

AN - 72379380; 11771547 AB - High-LET particles (HLP) of space radiation in the brain were measured with plastic nuclear track detectors (PNTD) using a life-size human phantom in the 9th Shuttle-Mir Mission (STS-91). Relationship between PNTD track-formation sensitivity (S) and LET infinity H2O was examined using heavy-ion beams at NIRS-HIMAC. Average fluence of the HLP (HLP10) with LET infinity H2O greater than 10 keV micrometers-1 was evaluated as 1.3 x 10(4) n cm-2 for the 9.8-day low-Earth-orbit mission (400 km x 51.65 degrees). Based on a simple extrapolation of these data, probability of HLP10 hits to hippocampus cells and cell-nuclei were estimated to be 45% and 7.0%, respectively, in a 90-day ISS mission. For 1 year, 91% of cells and 25% of cell-nuclei will be hit by HLP10.

AN - 72379371; 11770521 AB - Inverse planning and intensity modulated (IM) X-ray beam treatment techniques can achieve significant improvements in dose distributions comparable to those obtained with forward planned proton beams. However, intensity modulation can also be applied to proton beams and further optimization in dose distribution can reasonably be expected. A comparative planning exercise between IM X-rays and IM proton beams was carried out on two different tumor cases: a pediatric rhabdomyosarcoma and a prostate cancer. Both IM X-rays and IM protons achieved equally homogenous coverage of the target volume in the two tumor sites. Predicted NTCPs were equally low for both treatment techniques. Nevertheless, a reduced low-to-medium dose to the organs at risk and a lesser integral non-target mean dose for IM protons in the two cases favored the use of IM proton beams.

AN - 72379338; 11770538 AB - The dual goals of optimizing clinical efficacy of hadrontherapy and determining radiation risk estimates for space research have intersected to a common focus for investigation of the biological effects of charged particles. This paper briefly highlights recent international progress at accelerator facilities engaged in both biological and clinical studies of the effects of particle beams, primarily protons, carbon and iron ions. Basic mechanisms of molecular, cellular and tissue responses continue under investigation for radiations with a range of ionization densities. Late normal tissue effects, including the risk of cancer in particular, are of importance for both research fields. International cooperation has enhanced the rate of progress as evidenced by recent publications. Specific areas of biomedical research related to the biological radiotoxicity of critical organs (especially the central nervous system), individual radiosensitivities to radiation carcinogenesis, and the analysis of effects in mixed radiation fields still require more research. Recommendations for addressing these issues are made.

AN - 72379335; 11771543 AB - DSBs (double-strand breaks) produced by densely ionizing space radiation are not located randomly in the genome: recent data indicate DSB clustering along chromosomes. DSB clustering at large scales, from >100 Mbp down to approximately 2 kbp, is modeled using a Monte-Carlo algorithm. A random-walk model of chromatin is combined with a track model, that predicts the radial distribution of energy from an ion, and the RLC (randomly-located-clusters) formalism, in software called DNAbreak. This model generalizes the random-breakage model, whose broken-stick fragment-size distribution is applicable to low-LET radiation. DSB induction due to track interaction with the DNA volume depends on the radiation quality parameter Q. This dose-independent parameter depends only weakly on LET. Multi-track, high-dose effects depend on the cluster intensity parameter lambda, proportional to fluence as defined by the RLC formalism. After lambda is determined by a numerical experiment, the model reduces to one adjustable parameter Q. The best numerical fits to the experimental data, determining Q, are obtained. The knowledge of lambda and Q allows us to give biophysically based extrapolations of high-dose DNA fragment-size data to low doses or to high LETs.

AN - 72379269; 11776260 AB - Exposure to low doses of 56Fe particles produces changes in neural function and behavior. The present experiments were designed to examine the effects of irradiation on the acquisition of a dopamine-mediated conditioned place preference (CPP). In the CPP procedure, rats are given an injection of the dopamine agonist amphetamine in one distinctive compartment and a saline injection in a different compartment of a three-compartment apparatus. Control rats develop a preference for the amphetamine-paired compartment. In contrast, rats exposed to 1 Gy of 56Fe particles fail to develop a similar preference. The results of the experiment indicate that exposure to low doses of heavy particles can disrupt the neural mechanisms that mediate the reinforcement of behavior.

AN - 72379231; 11776259 AB - Rat skin was exposed to the plateau region of the 1.0 GeV/nucleon 56Fe beam at the Brookhaven AGS. Rats were irradiated or not with single of split doses of 56Fe or argon; some 56Fe-exposed rats were fed 250 ppm retinyl acetate continuously in the lab chow beginning 1 week before irradiation. All lesions were noted, photographed and identified for eventual histological diagnosis. The preponderance of the tumors so far are fibromas. The data show that single doses of 56Fe ions are 2 or 3 fold more effective than argon in producing tumors at 4.5 Gy but are about equally effective at 3.0 Gy and 9.0 Gy. The presence of 250 ppm retinyl acetate in the lab chow reduced the incidence of tumors by about 50-60% in comparison to groups exposed only to the radiation. These are preliminary findings based on only about one-fourth the eventual number of tumors expected.

AN - 72379224; 11776256 AB - The search for parameters of different nature to quantify radiation damage is carrying on from many years in humans and lab animals. The polyamines (spermidine and spermine) are ubiquitous polycations with many metabolic functions and can be easily assayed by HPLC method. Their involvement in cell proliferation has been evidenced in healthy and tumour tissues. Statistically significant reductions have been demonstrated in tissues and in red blood cells (RBC), in animals and in patients treated by total body irradiation (TBI) before bone marrow transplantation (BMT). In rats submitted to TBI with 3 Gy of gamma radiations, tissue polyamines significantly decrease during the early phase of injury in tissues with high proliferative activity (small intestine, spleen) whereas do not show any modification in kidney. When recovery takes place, the polyamines significantly increase and return to control levels when a normal morphology is restored. In patients submitted to radiation therapy, polyamines have been determined in urine and in RBC of patients with carcinoma of uterine cervix, head and neck and prostate, treated by external radiotherapy, and with thyroid cancer treated with iodine-131 therapy. The most interesting results has been obtained with RBC: in patients treated on the pelvis for prostate cancer a significant reduction during radiotherapy occurs, followed by the maintenance of low levels in patients with favourable outcome. It should be noted that polyamine levels before treatment appeared significantly higher than in healthy controls. After TBI the RBC polyamines show a dramatic fall to extremely low levels during the phase of marrow aplasia. The values show an increase corresponding to the engraftment of transplanted cells and to the following marrow repopulation. These evidences make the RBC polyamines very interesting parameters to monitor the radiation effects on humans.

AN - 72379011; 11770528 AB - The Atominstitute of the Austrian Universities developed the HTR-method for determination of absorbed dose and "averaged" linear energy transfer (LET) in mixed radiation fields. The method was applied with great success during several space missions (e.g. STS-60, STS-63, BION-10 and BION-11) and on space station MIR in the past 10 years. It utilises the changes of peak height ratios in LiF thermoluminescent glowcurves in dependence on the LET. Due to the small size of these dosemeters the HTR-method can be used also for measurements inside tissue equivalent phantoms. A water filled phantom with a diameter of 35 cm containing four channels where dosemeters can be exposed in different depths was developed by the Institute for Biomedical Problems. This opens the possibility to measure the depth distribution of the average LET and the dose equivalent simultaneously. During phase 1 dosemeters were exposed for 271 days (05.1997-02.1998) in 6 different depths inside the phantom, which was positioned in the commander cabin. In phase 2 dosemeters were exposed in 2 channels in 6 different depths for 102 days (05.1998-08.1998) in the board engineer cabin, following an exposure in different channels in 3 different depths for 199 days (08.1998- 02.1999) in the Modul KWANT 2.

AN - 72379001; 11776264 AB - In the endeavour to assess radiation risks for humans in space the concerted action of all stimuli (e.g. radiation and microgravity) has to be known already at a cellular level. The introduction of reporter genes into mammalian cells which allows the visualisation of modified gene expression levels, signal transduction rates and cell metabolism activities will supply basic information on the cellular response to space radiation. The cloning of the gene for green fluorescent protein (GFP) from the jellyfish Aequorea victoria and its subsequent expression in heterologous systems has established GFP as a unique genetic reporter system for use in a variety of organisms. Unlike other reporters, GFP fluorescence emerges in the absence of substrates or cofactors and allows for non-invasive monitoring in living and in paraformaldehyde-fixed cells. Enhancement of wild-type GFP by human codon optimisation and fluorophore mutation (EGFP) resulted in higher expression levels in mammalian cells and brighter fluorescence. The suitability of EGFP for gene expression studies to be performed on the ISS is shown for recombinant mammalian cells in response to UVC exposure.

AN - 72378956; 11776263 AB - Manipulation of checkpoint response to DNA damage can be developed as a means for protecting astronauts from the adverse effects of unexpected, or background exposures to ionizing radiation. To achieve this goal reagents need to be developed that protect cells from radiation injury by prolonging checkpoint response, thus promoting repair. We present evidence for a low molecular weight substance excreted by cells that dramatically increases the duration of the G2-delay. This compound is termed G2-Arrest Modulating Activity (GAMA). A rat cell line (A1-5) generated by transforming rat embryo fibroblasts with a temperature sensitive form of p53 plus H-ras demonstrates a dramatic increase in radiation resistance after exposure to low LET radiation that is not associated with an increase in the efficiency of rejoining of DNA double strand breaks. Radioresistance in this cell line correlates with a dramatic increase in the duration of the G2 arrest that is modulated by a GAMA produced by actively growing cells. The properties of GAMA suggest that it is a low molecular weight heat-stable peptide. Further characterization of this substance and elucidation of its mechanism of action may allow the development of a biological response modifier with potential applications as a radioprotector. GAMA may be useful for protecting astronauts from radiation injury as preliminary evidence suggests that it is able to modulate the response of cells exposed to heavy ion radiation, similar to that encountered in outer space.

AN - 72378906; 11770535 AB - Over the past two decades event by event Monte Carlo track structure codes have increasingly been used for biophysical modelling and radiotherapy. Advent of these codes has helped to shed light on many aspects of microdosimetry and mechanism of damage by ionising radiation in the cell. These codes have continuously been modified to include new improved cross sections and computational techniques. This paper provides a summary of input data for ionizations, excitations and elastic scattering cross sections for event by event Monte Carlo track structure simulations for electrons and ions in the form of parametric equations, which makes it easy to reproduce the data. Stopping power and radial distribution of dose are presented for ions and compared with experimental data. A model is described for simulation of full slowing down of proton tracks in water in the range 1 keV to 1 MeV. Modelling and calculations are presented for the response of a TEPC proportional counter irradiated with 5 MeV alpha-particles. Distributions are presented for the wall and wall-less counters. Data shows contribution of indirect effects to the lineal energy distribution for the wall counters responses even at such a low ion energy.

AN - 72378853; 11771542 AB - Space travellers are irradiated with cosmic rays to a dose rate considerably higher than that received on earth. In order to make sensible judgements about space exploration, the risks to health of such radiation need to be assessed. Part of the assessment of risk is to allow for the enhanced biological effectiveness of high LET radiations with respect to others. In space the high LET radiations of concern are high energy neutrons and charged particles. At the doses and dose rates encountered in space, the important risk is the induction of cancer in the astronauts. For this biological end-point there is no direct human evidence for the relative effectiveness of these radiations. There are some data for neutrons for cancer and life-shortening in laboratory animals but these are for fission spectra neutrons, which are of lower energy than those encountered in space. There is a small amount of data for protons and high energy heavier charged particles. The remaining evidence comes from cellular experiments observing chromosome aberrations and gene mutations. From this sparse information, pragmatic choices need to be made for application to protection in space. The data are reviewed and the bases for the pragmatic choices discussed.

AN - 72378834; 11776255 AB - Radiation dosimetry has been developed by means of physical, chemical and biological methods. A different approach to calculate the absorbed dose is related to the assay in body fluids of some molecules that modify their concentration after irradiation. The salivary glands in humans appear particularly radiosensitive and the effects of ionizing radiation can be evaluated by means of the determination of serum amylase (produced by acinar cells) and Tissue Polypeptide Antigen (TPA, synthesized by ductal cells). Patients submitted to external radiotherapy for tumours localized in the head and neck region show early and late effects on salivary glands. The modification of amylase activity and TPA appear as a progressive statistically significant increase within two days. Levels of 200-300% of baseline value are reached, followed by a rapid return to preirradiation levels. The use of different doses per fraction and fractionation schedules (conventional or multiple daily fractionations) confirm the direct correlation between the absorbed dose and serum amylase and TPA levels. It is worth noting that the irradiation of pancreas region did not produce any effect on amylase activity. The correlation may be assumed as linear for a short dose range (2-6 Gy) whereas in the range from 0.5 to 10 Gy a sigmoid curve represents the experimental data. Both molecules confirm their capability to quantify the absorbed dose in patients with thyroid carcinoma submitted to metabolic treatment with iodine-131. The effects of radiation are species-specific and are absent in laboratory mammals. The easiness of the determination of serum amylase and TPA lead us to propose the test as biochemical dosimeter for cosmic rays exposure during prolonged staying in the space.

AN - 72378665; 11776257 AB - Transgenic animals, with the integrated target gene, provide a unique approach for measuring and characterizing mutations in any tissue of the animal. We are using the plasmid-based lacZ transgenic mice with different p53 genetic background to examine radiation-induced genetic damage resulting from exposure to heavy particle radiation. We measured lacZ mutation frequencies (MF) in the brain and spleen tissues at various times after exposing animals to an acute dose of 1 Gy of 1GeV/amu iron particles. MF in the spleen of p53+/+ animals increased up to 2.6-fold above spontaneous levels at 8 weeks post irradiation. In contrast, brain MF from the same animals increased 1.7-fold above controls in the same period. In the p53-/- animals, brain MF increased to 2.2-fold above spontaneous levels at 1 week after treatment, but returned to control levels thereafter. Radiation also induced alterations in the spectrum of mutants in both tissues, accompanied by changes in the frequency of mutants with deletions extending past the transgene into mouse genomic DNA. Our results indicate that the accumulation of transgene MF after radiation exposure is dependant on the tissue examined as well as the p53 genetic background of the animals.

AN - 72378590; 11776276 AB - To estimate the effects of space radiation on health of space crews, we aimed to clarify whether g-ray-irradiation at a low-dose-rate interferes in a p53 centered signal transduction pathway induced by radiation in human cultured cells and CB-17 Icr+/+ mice. In vitro experiments, the human cultured squamous cell carcinoma cells (SAS/neo) were examined for cellular levels of p53 and Bax, and the incidence of apoptosis after irradiation at a low-dose-rate (1 mGy/min) or a high-dose-rate (1 Gy/min). It was found that challenging irradiation-induced apoptosis was depressed by chronic irradiation at 1.5 Gy for 25 h with the depression of p53 and Bax accumulation. In vivo experiments, a significant suppression of Bax and apoptosis induced by challenging irradiation at 3.0 Gy was observed when the mice were pre-irradiated chronically at 1.5 Gy for 25 h in the spleen of CB-17 Icr+/+ mice. These findings suggest that chronic pre-irradiation suppressed p53 function through radiation-induced signaling and/or p53 stability.

AN - 72378302; 11771537 AB - In order to study biological effects from cyclic dose rates encountered at the low-Earth orbit (LEO), an experimental facility was designed in the Biology room of the Heavy Ion Medical Accelerator in Chiba (NIRS-HIMAC). An incubator placed in this facility is irradiated repeatedly by secondary radiations from HZE-particle beams supplied for independent users. The daily-average dose rate (1.4 mGy d-1) measured for 223 days and short-term dose rates measured for selected beam conditions were comparable to the dose rates observed in past LEO missions. Severe solar particle events can be simulated with hourly maximum dose rate of 2.8 mGy h-1. Preliminary measurements using CR-39 and TLD indicated that the dominant LET range is less than 5 keV micrometers-1.

AN - 72378278; 11776254 AB - Wistar rats were exposed to high-mass, high energy (HZE) 56Fe particles (1000 GeV/AMU) using the Alternating Gradient Synchrotron (AGS). The animals were sacrificed at 1-5 hours or after a 30-day recovery period. The frequency of micronuclei in the tracheal and the deep lung epithelial cells were evaluated. The relative effectiveness of 56Fe, for the induction of initial chromosome damage in the form of micronuclei, was compared to damage produced in the same biological system exposed to other types of high and low-LET radiation. It was demonstrated that for animals sacrificed at short times after exposure, the tracheal and lung epithelial cells, the 56Fe particles were 3.3 and 1.3 times as effective as 60Co in production of micronuclei, respectively. The effectiveness was also compared to that for exposure to inhaled radon. With this comparison, the 56Fe exposure of the tracheal epithelial cells and the lung epithelial cells were only 0.18 and 0.20 times as effective as radon in the production of the initial cytogenetic damage. It was suggested that the low relative effectiveness was related to potential for 'wasted energy' from the core of the 56Fe particles. When the animals were sacrificed after 30 days, the slopes of the dose-response relationships, which reflect the remaining level of damage, decreased by a factor of 10 for both the tracheal and lung epithelial cells. In both cases, the slope of the dose-response lines were no longer significantly different from zero, and the r2 values were very high. Lung epithelial cells, isolated from the animals sacrificed hours after exposure, were maintained in culture, and the micronuclei frequency evaluated after 4 and 6 subcultures. These cells were harvested at 24 and 36 days after the exposure. There was no dose-response detected in these cultures and no signs of genomic instability at either sample time.

AN - 72377721; 11776258 AB - Using the new transgenic mice produced by mating gpt delta with p53 knockout, mutation induction by heavy-ion irradiation and the effect of p53 background on such induction were studied. After the whole body irradiation with 10 Gy of 135 MeV/u carbon-ion beam, the genomic DNA was isolated from the different organs and the lambda DNA was rescued as a phage. Mutations in the transgene on the lambda DNA were determined by the spi(-) selection (deletion assay). The spi(-) mutation was induced by the above irradiation, but enhancement of the mutant frequency by the knockout of p53 gene was found not in the phages recovered from liver but in those from kidney. We are now making an effort to determine the nature of spi(-) mutation to confirm such p53 effect.

AN - 72377617; 11770547 AB - Calculations of mortality due to secondary cancer have been investigated for its use in comparative treatment planning. A patient with Hodgkin's disease has been chosen as an example and has been planned with different radiation treatment modalities using photons and protons. The ICRP calculation scheme has been used to calculate mortality from dose distributions. To this purpose target volumes as well as critical structures have been outlined in the CT set of a patient with Hodgkin's disease. Dose distributions have been calculated using conventional as well as intensity modulated treatment techniques using photon and proton radiation. From the mean doses of each organ the mortality has been derived. Our work suggests that calculations of mortality can be useful in comparative treatment planning. Such mortality calculations can be helpful to find decisions between radiotherapy treatment techniques (intensity modulated or conventional treatment) or between different types of radiation (photons, electrons, protons, neutrons).

It has been used in analyzing recent experimental data obtained with monolayer cells irradiated at definite values of LET (in different parts of Bragg peaks). The new approach allows not only deriving the values of inactivation probabilities at given LET values; unexpected consequences seem to follow especially for inactivation characteristics of carbon ions in different parts of the Bragg peak, too.

AN - 72377350; 11771544 AB - Recent analysis of epidemiological studies using the two-stage clonal expansion (TSCE) model has shown that radiation-induced promotion dominates radiation-induced initiation for protracted exposures to radon. This strong promotion effect (i.e. enhanced proliferation of already-initiated cells) causes a pronounced 'inverse dose-rate effect', but by a mechanism completely different from those usually discussed in this connection. This rather startling result is discussed along with implications to extended space missions that include a significant amount of high-LET radiation. It is suggested that the effect might be caused by a 'Bystander Effect' by which normal cells in the vicinity of initiated cells are hit by alpha particles and send out signals that modify the cell kinetics of the already-initiated clones.

AN - 72377270; 11771538 AB - We have designed and built an integrating ion imaging system (I3) that records the spatial distribution of the dose of heavy ions incident on samples irradiated at the radiobiology beamline of the Alternating Gradient Synchrotron at Brookhaven National Laboratory. The images of dose are integrated over the duration of the exposure. Unlike the images formed on X-ray film, these images are linear with the incident dose. Heavy ions are incident on a phosphor that is located just behind the sample position. Visible light emitted from the phosphor is collected by a lens and focused onto a scientific grade charge coupled device (CCD) cooled to about -45 degrees C. The phosphor and CCD camera are integral parts of a modular sample holder designed for irradiating molecular samples, which is easily mounted on the sample platform of the beamline. The imager can be adapted to other types of samples. The present CCD image is digitized to 14 bits (16,384 intensity levels), but the dynamic range is extended by adjusting the aperture of the CCD camera lens. Digital images from the CCD are routinely transferred over the BNL local area network for archival storage on a UNIX server, from which they can be opened from any authorized computer with access to the Internet. Images obtained with no sample in place record the dose at all points on the target field. When a sample is in place, an image of the sample appears providing its exact location with respect to fiducial marks recorded for all images. Areas surrounding the image of the sample are used in comparison with companion no-sample images to get exact doses over the sample. The contrast mechanism responsible for image formation is the shift along the Bragg curve resulting from loss of energy of the ions as they pass through the sample--not from a change in ion flux reaching the phosphor. The sharpness of the images formed with the DNA samples we have recorded indicates that neither scattering of the incident heavy ions or the generation of secondary ions contribute significantly.

AN - 72377214; 11770529 AB - A major problem in manned space flight is the impact of cosmic radiation, especially that of heavy charged particles since they have an elevated biological efficiency (RBE). The RBE estimation determines the potential exposure for man. It is one of the limiting factors for space flight and should be known very precisely. The same is true for heavy-ion tumor therapy where beams of carbon ions are used to treat deep-seated tumors. There, RBE values determine the dose distribution and are estimated using the Local Effect Model (LEM). The clinical results confirm the correctness of LEM and suggest to use the same theoretical approach to assess the impact of cosmic rays.

AN - 72375387; 11770531 AB - The possible risk of induced malignancies in astronauts, as a consequence of the radiation environment in space, is a factor of concern for long term missions. Cancer risk estimates for high doses of low LET radiation are available from the epidemiological studies of the A-bomb survivors. Cancer risks at lower doses cannot be detected in epidemiological studies and must be inferred by extrapolation from the high dose risks. The standard setting bodies, such as the ICRP recommend a linear, no-threshold extrapolation of risks from high to low doses, but this is controversial. A study of mechanisms of carcinogenesis may shed some light on the validity of a linear extrapolation. The multi-step nature of carcinogenesis suggests that the role of radiation may be to induce a mutation leading to a mutator phenotype. High energy Fe ions, such as those encountered in space are highly effective in inducing genomic instability. Experiments involving the single particle microbeam have demonstrated a "bystander effect", ie a biological effect in cells not themselves hit, but in close proximity to those that are, as well as the induction of mutations in cells where only the cytoplasm, and not the nucleus, have been traversed by a charged particle. These recent experiments cast doubt on the validity of a simple linear extrapolation, but the data are so far fragmentary and conflicting. More studies are necessary. While mechanistic studies cannot replace epidemiology as a source of quantitative risk estimates, they may shed some light on the shape of the dose response relationship and therefore on the limitations of a linear extrapolation to low doses.

AN - 72374885; 11771551 AB - Assuming that the number of ionizations events within short segments of DNA-size volumes is a major factor of the biological effectiveness of ionizing radiation, we have designed and manufactured a new nanodosimetric detector counting ionization events in small wall-less gas volumes, which simulate such DNA segments. The detector measures individual ionizations in low-pressure (~1 Torr) propane or any other gas corresponding to a tissue-equivalent cylindrical volume of 2-4 nm diameter and up to 30 nm length. While first nanodosimetric event spectra with protons and alpha particles are being obtained, it is important to develop and test a theory that relates these spectra to biological endpoints such as strand breakage, mutations, and lethal cellular events. This paper describes the two-compartment theory, which is based on the premise that energy deposition in nanometer sites can be broadly divided into two categories: a low-energy deposition compartment comprising events with a total number of 2-5 ionizations, and a high-energy deposition compartment comprising events containing 6-10 ionizations. Under standard biochemical conditions, these events will lead to different biological consequences. The fate of DNA lesions produced by low-energy deposition events will mostly depend on the repair capacity of the irradiated cells, whereas events produced by high-energy deposition events will be irreparable. These events are therefore the biologically most relevant lesions, since they inevitably lead to mutation and cell death.

AN - 72373718; 11770537 AB - It has been over 40 years since occupational radiation exposures to NASA's astronauts began and more than 300 individuals have been exposed to low and intermediate doses of trapped protons and galactic cosmic rays (GCR). The International Space Station (ISS) will add substantially to this number and significantly increase average lifetime doses. We review these exposures in this report. After many years of investigation, the method used to assess risk have not changed significantly. However, molecular biology and genetics have made enormous progress in establishing the mechanisms of cancer formation, damage to the central nervous system, and individual variation in sensitivity to radiation. We discuss critical questions and possible new approaches to the prediction of risk from space radiation exposures. Experimental models can lead to testable theories that along with extensive biophysical and informatics approaches, will lead to fame and fortune by allowing for accurate projections of astronaut risks and for the development of biological countermeasures.

AN - 72373466; 11770520 AB - Space radiation research had a significant impact in the past. The physical interaction of heavy charged particles with living matter and the development of models, including microdosimetry, were stimulated by problems encountered in space. New phenomena were discovered. Advanced dosimetric techniques had to be developed and computational methods to describe the radiation field in space. The understanding of the radiobiology of heavy ions, necessary for a well-founded risk assessment and prompted by space radiation research, constitutes also the basis for heavy ion radiotherapy. So far unknown areas like the interaction of microgravity and radiation were opened. The space station will give even more opportunities. For the first time it will be possible to investigate animals for a longer time under the influence of both microgravity and radiation. Living systems can be exposed under well defined conditions with parallel physical measurements. Solar particle events are still an unsolved problem. Significant improvement in their predictability and quantitative description can be expected. All this will not only give exciting opportunities for research but will also translate into immediate benefit for human beings. This paper will attempt to give an overview of the past achievements and glance into the future.

AN - 72302521; 11725783 AB - In spacecraft water recovery systems there is a need to develop a postprocessor water polishing system to remove organic impurities to levels below 250 micrograms/L (ppb) with a minimum use of expendables. This article addresses the development of a photocatalytic process as a postprocessor water polishing system that is microgravity compatible, operates at room temperature, and requires only a minimal use of both oxygen gas (or air) and electrical power for low energy UV-A (315-400 nm) lamps. In the photocatalytic process, organic contaminants are degraded to benign end products on semiconductor surfaces, usually TiO2. Some challenging issues related to the use of TiO2 for the degradation of organic contaminants have been addressed. These include: i) efficient and stable catalytic material; ii) immobilization of the catalyst to produce a high surface area material that can be used in packed-bed reactors, iii) effective light penetration, iv) effective, microgravity-compatible, oxidant delivery; v) reduced pressure drop, and vi) minimum retention time. The research and development performed on this photocatalytic process is presented in detail. Grant numbers: NAS9-97182.

AN - 72301712; 11724073 AB - A rapid, simple, and direct (RSD) assay of eluate from filter concentration was developed to enumerate low numbers of MS2 bacteriophage, used as a surrogate for enteric viruses, from samples collected from a prototype-sized water recycling system. The RSD assay utilized a 50-ml eluate volume in a modified single-layer assay, neutralizing eluate pH by buffered, double-strength agar. The RSD assay developed was simpler and minimized sample-handling steps compared with another published method. The RSD assay method showed greater sensitivity than the other published method for recovering phage from filter eluate while avoiding pH shifts, which can inactivate phage. Grant numbers: NAGW 2356.

AN - 72301146; 11725785 AB - The development of a microgravity-compatible analyzer capable of quantifying organic acids in water is described. The analyzer employs "reagentless" solid phase acidification to convert organic acids to the volatile form followed by membrane separation and specific conductance detection to determine organic acids at concentrations between 0.005 and 40 mg/L. In the future, this technology will be extended to the detection of alcohols, which will be oxidized to form the corresponding organic acid and then determined using the same processes. An immobilized enzyme biocatalyst, alcohol oxidase, oxidizes alcohols to form an aldehyde. Oxidation to the corresponding organic acid is then completed over a heterogeneous catalyst. The combined organic acid and alcohol monitor (OAAM) will be utilized to determine levels of both analyte classes at various points within the water recovery system (WRS) baselined for the International Space Station (ISS). These data will improve water quality through enhanced process control, while allowing early diagnosis of potential problems. Grant numbers: NAG9-1081.

AN - 72300049; 11724072 AB - Soybeans have been selected to be grown in a habitat (BIO-Plex, Bioregenerative Planetary Life Support Systems Test Complex) designed to evaluate advanced life support systems for long-duration space missions. Soymilk and soy bread will be incorporated into this nutritious, plant-based food system. Because all consumables will be recycled and reused, food safety is a particular concern. Critical control points were identified to control microbiological hazards, particularly mycotoxins, and chemical hazards from antinutrients and volatiles emitted during processing of soymilk and soy bread. Volatile compounds, evolved during the manufacturing of soymilk and soy bread, were quantified by GC/MS to assess their impact on this closed loop system. All concentrations of volatiles evolved during soymilk production were below the 24-h Space Craft Maximum Allowable Concentration (SMAC), while acetaldehyde surpassed the SMAC criteria for soy bread. Recommendations were made for processing of soybeans in such environments to minimize risk to crew member health.

AN - 72223231; 11676457 AB - The CELSS resource recovery system, which is a waste-processing system, uses aerobic and anaerobic bioreactors to recover plants nutrients and secondary foods from the inedible biomass. The anaerobic degradation of the inedible biomass, by means of culture of rumen bacteria, generates organic compounds such as volatile fatty acids (VFA) (acetic, propionic, butyric) and ammonia. The presence of VFA in the bioreactor medium at fairly low concentrations decreases the microbial population's metabolic reactions due to end-product inhibition. Technologies to remove VFA continuously from the bioreactor are of high interest. Several candidate technologies were analyzed, such as organic solvent liquid-liquid extraction, adsorption and/or ion exchange, dialysis, electrodialysis, and pressure-driven membrane separation processes. The proposed technique for the on-line removal of VFA from the anaerobic bioreactor was a nanofiltration membrane recycle bioreactor. In order to establish the nanofiltration process performance variables before coupling it to the bioreactor, a series of experiments was carried out using a 10,000 molecular weight cutoff (MWCO) tubular ceramic membrane module. The variables studied were the bioreactor slurry permeation characteristics, such as: the permeate flux, VFA and nutrient removal rates as a function of applied transmembrane pressure, fluid recirculation velocity, suspended matter concentration, and process operating time. Results indicated that the permeate flux, VFA, and nutrients removal rates are directly proportional to the fluid recirculation velocity in the range between 0.6 and 1.0 m/s, applied pressure when these are lower than 1.5 bar, and inversely proportional to the total suspended solids concentration in the range between 23,466 and 34,880 mg/L. At applied pressure higher than 1.5 bar the flux is not more linearly dependent due to concentration polarization and fouling effects over the membrane surface. It was also found that the permeate flux declines rapidly during the first 5-8 h, and then levels off with a diminishing rate of flux decay.

AN - 71336104; 12213997 AB - Methylamine (MA), a component of serum and a metabolite of nicotine and certain insecticides and herbicides, is metabolized by semicarbazide-sensitive amine oxidase (SSAO). MA is toxic to cultured human umbilical vein and calf pulmonary artery endothelial cells. Endothelial cells, which do not exhibit endogenous SSAO activity, are exposed to SSAO circulating in serum. In contrast, vascular smooth muscle cells (VSMC) do exhibit innate SSAO activity both in vivo and in vitro. This property, together with the critical localization of VSMC within the arterial wall, led us to investigate the potential toxicity of MA to VSMC. Cultured rat VSMC were treated with MA (10-5 to 1 M). In some cultures, SSAO was selectively inhibited with semicarbazide or MDL-72145 [(E)-2-(3,4-dimethoxyphenyl)-3-fluoroallylamine]. Cytotoxicity was measured via MTT, vital dye exclusion, and clonogenic assays. MA proved to be toxic to VSMC only at relatively high concentrations (LC(50) of 0.1 M). The inhibition of SSAO with semicarbazide or MDL-72145 did not increase MA toxicity, suggesting that the production of formaldehyde via tissue-bound, SSAO-mediated MA metabolism does not play a role in the minimal toxicity observed in isolated rat VSMC. The omission of fetal calf serum (FCS), which contains high SSAO activity, from media similarly showed little effect on cytotoxicity. We conclude that VSMC--in contrast to previous results in endothelial cells--are relatively resistant to MA toxicity, and SSAO does not play a role in VSMC injury by MA.

AN - 71190955; 11570422 AB - Arrays of broadly responsive vapor detectors can be used to detect, identify, and quantify vapors and vapor mixtures. One implementation of this strategy involves the use of arrays of chemically-sensitive resistors made from conducting polymer composites. Sorption of an analyte into the polymer composite detector leads to swelling of the film material. The swelling is in turn transduced into a change in electrical resistance because the detector films consist of polymers filled with conducting particles such as carbon black. The differential sorption, and thus differential swelling, of an analyte into each polymer composite in the array produces a unique pattern for each different analyte of interest, Pattern recognition algorithms are then used to analyze the multivariate data arising from the responses of such a detector array. Chiral detector films can provide differential detection of the presence of certain chiral organic vapor analytes. Aspects of the spaceflight qualification and deployment of such a detector array, along with its performance for certain analytes of interest in manned life support applications, are reviewed and summarized in this article.

AN - 70574563; 11121216 AB - Although biophysical models predict a difference in the ratio of interchromosomal to intrachromosomal interarm exchanges (F ratio) for low- and high-LET radiations, few experimental data support this prediction. However, the F ratios in experiments to date have been generated using data on chromosome aberrations in samples collected at the first postirradiation mitosis, which may not be indicative of the aberrations formed in interphase after exposure to high-LET radiations. In the present study, we exposed human lymphocytes in vitro to 2 and 5 Gy of gamma rays and 3 Gy of 1 GeV/nucleon iron ions (LET = 140 keV/micrometer), stimulated the cells to grow with phytohemagglutinin (PHA), and collected the condensed chromosomes after 48 h of incubation using both chemically induced premature chromosome condensation (PCC) and the conventional metaphase techniques. The PCC technique used here condenses chromosomes mostly in the G(2) phase of the cell cycle. The F ratio was calculated using data on asymmetrical chromosome aberrations in both the PCC and metaphase samples. It was found that the F ratios were similar for the samples irradiated with low- and high-LET radiation and collected at metaphase. However, for irradiated samples assayed by PCC, the F ratio was found to be 8.2 +/- 2.0 for 5 Gy gamma rays and 5.2 +/- 0.9 for 3 Gy iron ions. The distribution of the aberrations indicated that, in the PCC samples irradiated with iron ions, most of the centric rings occurred in spreads containing five or more asymmetrical aberrations. These heavily damaged cells, which were either less likely to reach mitosis or may reach mitosis at a later time, were responsible for the difference in the F ratios generated from interphase and metaphase analysis after exposure to iron ions.

AN - 62259339; ED463684 AB - This report summarizes the result of a survey of undergraduate general education in a national sample of colleges and universities. It was conducted during 2000 through two electronic surveys; one of chief academic officers and a second directed to the administrator most responsible for day-to-day administration of a general education program. Responses were received from 279 chief academic officers and 200 general education administrators. One of the most surprising findings was that general education remains a high priority item on the majority of campuses, with 57% of the responding institutions currently conducting a formal review of the general education program, and 43% planning a review in the next year. Over the last 10 years, general education has increased as an educational priority. General education reforms of the past decade have resulted in a variety of new approaches, including increased interest in thematic programs. In spite of the high level of interest in general education from campus and external sources, there is little evidence that academic leaders have made many advances in developing shared educational values and embedding them in the life of the institution. Students often display a preference for specialized study, and the advance of general education is slowed by the organization and values of the academy itself. An appendix contains a profile of responding institutions. (Contains 14 references.) (SLD) AU - Ratcliff, James L. AU - Johnson, Kent D. AU - La Nasa, Steven M. AU - Gaff, Jerry G.

The fluctuations in pollen and spores reflect the local hydrological events and regional climate changes. The data show that larch (Larix dahurica) forests with shrub alder (Alnus fruticosa) and dwarf birch (Betula exilis) dominated the area during the last 6400 yr BP. There is no evidence for tree-line fluctuations at the sites during the latter half of the Holocene. Climate reconstructions made by transfer function from one site show that the warmest time was between 6000 and 4500 yr BP.

A literature survey reveals that decay constants used in geo- and cosmochronology usually are assigned uncertainties of ca. 1% but that there are very much larger unaccounted discrepancies between decay constants reported by different "counting groups" as well as differences between results derived from counting experiments and from the comparison of ages obtained on the same samples by utilizing different radioactive clocks. An extension and partial revision of the decay constants recommended in 1976 for adoption in geo- and cosmochronology by the International Union of Geological Sciences (IUGS) appears both desirable and feasible, given the analytical improvements of the last 20 years. We call for a concerted effort to achieve improvements in the near future. For this it will be necessary to rigorously evaluate counting biases in counting determinations, initial daughter contamination for ingrowth experiments, and the existence of truly "point-like" geological events for age comparison approaches.

It was wet sieved in 1970 and dry sieved in 1971 with different results. Therefore, some doubt about its grain-size distribution persists. We consider allocation inhomogeneity, if any, to be a minor cause for the discrepancy. Rather, the difference in methodology is likely to be the major cause for different results. We report the results of a new analysis of an allocation of 0.99 g using the contemporary method of wet sieving at Johnson Space Center; this method uses water instead of freon. Our results show that the mean grain size and sorting of the submillimeter fraction of soil 10084 are 4.28phi (= 51 mu m), and 2.23phi (= 213 mu m), respectively. A significant proportion (14.2%) of the soil is in the <10 mu m size range, which contrasts to previous determinations of 6.4% and 9.8%, respectively. The newly determined grain-size distribution is skewed towards the finest grain sizes. This result is more compatible with the high maturity of this soil than the results of previous determinations.

Definite trends can be seen in optical properties of size separates with decreasing particle size: diminished spectral contrast and a steeper continuum slope. These trends are related to space weathering processes and their affects on different size fractions. The finest fraction (defined here as the <10 mu m fraction) appears to be enriched in weathering products relative to the larger size fractions, as would be expected for surface correlated processes. This <10 mu m fraction tends to exhibit very little spectral contrast, often with no distinguishable ferrous iron absorption bands. Additionally, the finest fractions of highland soils are observed to have very different spectral properties than the equivalent fraction of mare soils when compared with larger size fractions. The spectra of the finest fraction of feldspathic soils flatten at longer wavelengths, whereas those of the finest fraction of basaltic soils continue to increase in a steep, almost linear fashion. This compositional distinction is due to differences in the total amount of nanophase iron that accumulates in space weathering products. Such ground-truth information derived from the <10 mu m fraction of lunar soils provides valuable insight into optical properties to be expected in other space weathering environments such as the asteroids and Mercury.

A major issue in meteoritics is to determine the origin of meteoritic organics: are they mainly formed from CO in the solar nebula via a process such as Fischer-Tropsch, or are they derived from interstellar organics? In order to determine the role that Fischer-Tropsch catalysis may have played in the organic chemical evolution of the solar nebula, we have developed a kinetic model for this process. Our model results agree well with experimental data from several existing laboratory studies. In contrast, empirical rate equations, which have been derived from experimental rate data for a limited temperature (T) and pressure (P) range, are inconsistent with experimental rate data for higher T and lower P. We have applied our model to pressure and temperature profiles for the solar nebula, during the epoch in which meteorite parent bodies condensed and agglomerated. We find that, under nebular conditions, the conversion rate of CO to CH (sub 4) does not simply increase with temperature as the empirically-derived equations suggest. Instead, our model results show that this process would have been most efficient in a fairly narrow region that coincides with the present position of the asteroid belt. Our results support the hypothesis that Fischer-Tropsch catalysis may have played a role in solar nebula chemistry by converting CO into less volatile materials that can be much more readily processed in the nebula and in parent bodies.

This observable is affected, among other factors, by the Earth's solid and ocean tides. They induce long-period orbital perturbations that, over observational periods of few years, may alias the detection of the gravitomagnetic secular trend of interest. In this paper we calculate explicitly the most relevant tidal perturbations acting upon LAGEOSs and assess their influence on the detection of the Lense-Thirring effect. The present day level of knowledge of the solid and ocean tides allow us to conclude that their influence on it ranges from almost 4% over 4 years to less than 2% over 7 years.

Our results show that these molecules can be detected using this instrumentation to a high degree of mass accuracy. We believe that ToFSIMS can, therefore, be used to identify these molecules in environmental samples where sample size may be an issue and contraindicate the use of more traditional techniques such as GC-MS.

AN - 52125396; 2002-032825 AB - Although asteroid 4 Vesta and Vestoids have been believed to be the source of a group of basaltic meteorites called HEDs, there have been detailed spectral analyses on the spectral redness and the 506.5 nm absorption band, suggesting controversy on their space weathering processes and origins. In order to evaluate a possibility that such an apparent inconsistency may be explained by the space weathering, the 506.5 nm spectral feature and reddening trend are examined for Vesta and Vestoids, HED meteorites, lunar soils, and laser irradiated pyroxene samples in this paper. Our results indicate that all fresh HED meteorites have the 506.5 nm band at different wavelengths according to their classes, lunar soils seem to lose the 506.5 nm band as they mature, and pulse laser irradiation on the pyroxene sample seems to reduce the 506.5 nm band. Therefore, absence of the 506.5 nm band on some Vestoids can be due to space weathering although the relationship between the visible redness and presence/absence of the 506.5 nm band of Vesta and Vestoids is inconsistent with the assumed HED-lunar space weathering trend based on the above laboratory results. Other possible explanations are that some Vestoids experienced shock heavy enough to erase the 506.5 nm band and that pyroxenes on some Vestoids are not similar to those in HED meteorites. Even if the latter case is true and some Vestoids are not made of HED materials, HED meteorites could still come from Vesta unless we assume all Vestoids have to be fragments of Vesta.

The portion of Vesta's orbit at which such an event must have occurred is slightly constrained and depends on the hemisphere impacted. There is some evidence for subsequent disruptions of these ejected objects. Spectroscopy suggests that the dynamical family members are associated with material from Vesta's interior that was excavated by the event giving rise to the crater covering much of Vesta's southern hemisphere. The 505-nm pyroxene feature seen in HED meteorites is relatively absent in a sample of Vesta dynamical family members raising the question of whether this collisional event was the source of the HED meteorites. Asteroids spectroscopically associated with Vesta that possess this feature are dynamically distinct and could have arisen from a different collisional event on Vesta or originated from a body geochemically similar to Vesta that was disrupted early in the history of the solar system.

Ground resolution was 1 m and temperature sensitivity of the instrument was 0.1 degrees C. This imagery was analyzed to determine the location of springs for groundwater monitoring. Subsequently, 45 springs with flows ranging from a few ml/sec to approximately 280 liter/sec were located. Groundwater temperatures often differ little from mean annual surface air temperature. On thermography collected in the winter, springs show up as very warm spots. Many of the new springs were submerged in lakes, streams, or swamps; consequently, flow measurements were difficult. Without estimates of discharge, the impacts of contaminated discharges on surface streams would be difficult to evaluate. A flow rate was developed using the EPA code CORMIX. Sampling also showed that two springs on either side of a large creek had the same water source so that groundwater was able to pass beneath the creek. One of the springs is an estavelle (a spring during the wet season and a sink during the dry season) so that this feature is down-gradient from the other spring.

It is hypothesized that since Radarsat and SPOT images contain complementary information, flood mapping would be more efficient when the two image types are used in combination. A Radarsat scene, a SPOT scene, and a combination of the two were classified using the Mahalanobis distance algorithm. The results indicate that wetland flood mapping in summer conditions is feasible with about 80% accuracy when a combination of Radarsat and SPOT imagery is used.

The main objective is to generate knowledge of the key biophysical factors that control the water use by this vegetation community. Current results indicate that evaporation is often energy limited and close to the equilibrium rate, which reflects the fairly large extent of the vegetation corridor. However, there are times when the evaporation is largely controlled by saturation deficit, reflected in small values of the omega or coupling factor. This is most commonly observed during afternoons. The increase in saturation deficit during these times can result from horizontal advection of warm, dry air when winds blow across the corridor. Or it can result from the imposition of drier air from the mixed layer during the afternoon hours, when the ABL is strongly coupled to the surface. The results will be integrated with other physiological measurements made at the site. The findings will provide the direction for development of appropriate models for water use of this important ecosystem.

An atmospherically corrected image that does not incorporate emissivity is used for comparison purposes. The evaporation is derived as a function of a scaling of the surface radiant temperature field. The mean difference in evaporation between the emissivity corrected and uncorrected temperature images is 3 W m (super -2) . The evaporation estimates are shown to be insensitive to changes in temperature due to the emissivity effect; this however is likely a result of the way the temperature field is scaled.

The SEBAL method yielded high actual evapotranspiration (E (sub a) ) rates (<0.5 to 4 mm day (super -1) ), if relatively dense savanna vegetation was present, even when groundwater was over 40 m deep. The association between vegetation pattern and E (sub a) has been interpreted as due to significant uptake of water by deep roots. The mapping of the groundwater contribution to the evapotranspiration was provided through MODFLOW groundwater modelling using the evapotranspiration package with an extinction depth of 60 m. It is believed that a major part of the transpired water originates from the lower vadose zone. The validity of the satellite-derived E (sub a) flux is discussed.

As a consequence, there is no fluvial network and the lagoons or ponds located in the depressions are important. Landsat 5 TM images have shown good contrast between water and land areas. All available scenes between August 1998 and August 1999 were used in a multitemporal analysis. The areas of the lagoons, obtained by satellite images, in each period were compared with hydrological variables measured in situ. The results show a relationship between variations of the water balance (precipitation-evapotranspiration) and fluctuations of the water table and lagoon areas.

Inland areas surrounding the main flow system comprise a myriad of small lakes and wetlands, of which a large percentage are hydrologically disconnected or "perched" at elevations higher than adjacent lakes or channels. This large, complex and dynamic ecosystem has undergone substantial changes over the last 25 years. The remoteness of this site, along with a shortage of hydrological and ecological information, has necessitated the development of innovative methods to assess these changes. These methods include the analysis of Landsat, Radarsat and SPOT satellite imagery for verification and calibration of a hydrodynamic model to observed flood conditions. This unique coupling of imagery and a hydrodynamic model provides key validation points and initial conditions for model runs. The results of the techniques outlined in this paper provide a starting point to assess changes produced by flow regulation and climatic change.

It accounts for the influence of soil type and the effect of the prevailing evaporative demand, both of which effect the interrelations between near-surface water content, evaporative demand and soil surface resistance.

The region experiences long cold winters and short cool summers, resulting in a limited growth period. Fens and bogs are the dominant wetland types. The level of moisture saturation, chemistry, topography and climate influence the development of wetland systems. Slight changes in these environmental factors can significantly alter vegetation species and health. As persistent cloud cover often limits the utility of optical remotely sensed data in Atlantic Canada, the value of using the all-weather capabilities of radar data become evident. Temporal sequences of Radarsat images were acquired in May, June and August 1999. During each time period, four Radarsat scenes with incidence angles spanning 20-49 degrees (Standard 1, 4, 7 and Fine 1) were acquired. This paper describes changes in radar backscatter as a function of incidence angle, vegetation structure and moisture conditions.

CASI imagery covering the visible and near-infrared wavelengths (430-796 nm) was acquired for a 23 km (super 2) test area at the Starkey wellfield in Pasco County, Florida. Moderately to severely stressed (i.e. dewatered) cypress domes exhibited various degrees of tree mortality and canopy-thinning gaps, which were indicated by significantly lower NDVI values. Classification of cypress domes using CASI imagery accurately (98%) identified areas of intact cypress canopy, canopy gaps, standing water, wet prairies, and successional change in the understory. The results indicate that high resolution multispectral imagery could be used to remotely sense and map relevant ecological and hydrological indicators of wetland condition.

This project investigates whether new hyperspectral EO sensors provide enhanced accuracy and more detailed spatial context to aid the characterization of crop type and fractional ground cover. These are key input parameters in models of field and catchment scale nitrogen, phosphorus and sediment loss to streams. Such contemporary information, when coupled with supporting (e.g. digital elevation model) data, will help identify vulnerable areas and provide a framework for developing pollution risk assessment tools based on the spatial co-location of risk factors (slope, erodable soils, crop type).

Major nitrate sources include atmospheric deposition, fertilizers, animal waste and nitrification of soils and snow. Variations in delta (super 15) N have been successful in defining these sources in waters (Kendall, 1998). GIS techniques were combined with nitrate concentrations and hydrogen and nitrogen isotopic ratios of river waters to investigate the effect of land use on the water chemistry of the Connecticut River basin in northeastern USA. The results suggest urban development in the southern portion of the basin increases runoff rates and decreases soil residence times.

Therefore, a method was formulated to estimate the upward flux of water vapour through the dry surface layer of soil (DSL) from the difference in water content between its top and bottom surfaces; it is called the DSL method. The DSL bulk method is a simplified version of the DSL method, which needs only the measurements of soil surface temperature and mean volumetric water content for the 0-5 cm surface layer, both of which can be measured by remote sensing. This paper describes the formulation of the DSL method and a technique for estimating the daily evaporation from an instantaneous flux measured by the DSL bulk method in the afternoon.

Soil moisture and snow are especially key parameters, which should be observed at the global scale and included in global and regional models. In this study, new algorithms based on radiative transfer theory are developed for soil moisture and snow using passive microwave sensors. These are applied to data from the TRMM Microwave Imager and evaluated by using the field data obtained during the GAME-Tibet Intensive Observing Period. The estimated hydrological parameters, surface soil moisture, soil surface temperature and water content of vegetation and snow temperature show good correspondence to the observed data.

Comparisons of instantaneous spatially distributed upwind fluxes with values of groundbased measured fluxes using eddy correlation techniques and other micrometeorological instruments, were conducted for two different dates. Results show considerable differences between the fluxes that can be attributed to advection, canopy heat storage and wind variability. A careful footprint analysis will need to be conducted in the future to better match the ground-based and aircraft measurements.

Remote sensing offers an excellent means of determining near real time crop coefficients for most irrigated crops. In the absence of prior knowledge of planting, emergence and/or full effective cover dates, canopy reflectance can be used to establish the growth rate of the crop, and subsequently can be used to fractionalize the reference ET for irrigation scheduling. This paper presents the results of extending the reflectance-based crop coefficient methodology, initially developed for corn, to pink beans. Simulation results indicate that the reflectance-based coefficients follow the actual crop growth in the field, and thus can simulate the measured soil moisture content.

The correlation between radar backscatter (sigma (super o) ) and root mean square of surface roughness (rms) is above 80% and has allowed production of a Radarsat based map of bare soil roughness with three classes: rough, intermediate and smooth. The latter corresponds to the highest risk for excess runoff.

Extending approaches to whole basins or larger regions is difficult due to issues related to landscape heterogeneity and scale. Reliable areal estimates of ET are essential for accurate modelling of the hydrological cycle and for assessing water-use of different ecosystems. A riparian corridor along the Rio Grande (USA) dominated by Tamarisk (salt cedar) is being studied to determine daily and total seasonal water-use. Local estimates of ET in the Tamarisk were made using eddy covariance instrumentation mounted on two towers. Radiometric temperature at the top of the canopy was also measured using a fixed-head infrared thermometer. The combination of these data will be used to evaluate evapotranspiration estimates along the corridor using data remotely sensed from an aircraft platform that have been acquired periodically for a large extent of the riparian zone.

An understanding of the relationship between soil moisture content and vegetation condition is necessary to predict the impact of those events. In this paper we explore a methodological approach for early drought prediction. We hypothesize that the amplitude of the diurnal temperature cycle of a vegetated surface, determined using remote sensing measurements, can indicate soil moisture content and vegetation condition. We present a preliminary analysis of three months of soil moisture and temperature data collected at Skukuza, South Africa. The results support our basic hypothesis yet suggest that further work is required to better understand the coupling of these parameters. The SiB2 model will be adapted for this purpose.

Measures of irrigation productivity regard transpiration as a measure of crop growth and evaporation as an indicator of un-utilized water. Evapotranspiration (ET) may be estimated at a point from climate station data but estimating evapotranspiration over large areas such as irrigation schemes or river basins is more difficult. This paper compares two recent methods, remote sensing and hydrological modelling, that are able to compute areal estimates of evapotranspiration. First, estimates of evapotranspiration for the 17 200 km (super 2) Gediz Basin in western Turkey are made for a series of days in 1998 based on a feedback algorithm using data from the NOAA-AVHRR satellite sensor. Second, a distributed hydrological model is applied to the same basin and, as part of the daily vertical water balance, derives estimates of actual crop transpiration and soil evaporation for the 1998 irrigation season. Both methods estimate evapotranspiration for each land cover and location within the basin. Results show that remote sensing and model estimates of ET are in reasonable agreement.

To address this question, this work presents a hydrological model which allows for spatially varying model parameters. This particular distributed model incorporates components that are adaptations of operational models used often in a spatially-lumped manner to produce estimates of soil water, runoff and streamflow. A geographic information system is used to sub-divide the study basin into small subcatchment units with areas of up to a few hundred square kilometres. Soil water accounting and channel routing models are used to generate runoff and streamflow over the network of subcatchments and streams. The application illustrates that operational distributed modelling is feasible with present-day operational data, and that sensitivity analyses are necessary to understand the ramifications of the limitations of such data for operational forecasting with distributed models.

The model results of friction velocity and sensible heat flux are compared at the local scale to field data collected at 3 m height in five different crops and at the regional scale to data from a 48 m tall mast. At the local scale the model prediction is good for friction velocity but for sensible heat the model results still have some problem. At the regional scale both friction velocity and sensible heat flux are modelled with good results.

The project comprises three main components: (a) a software tool, SHYLOC, that uses a unique method to combine Landsat-TM images with digitized drainage or irrigation ditch networks to determine surface water storage; (b) a coupled hydrological and hydraulic modelling system that can incorporate hydraulic boundary conditions commonly associated with wetlands; and (c) a comprehensive hydro-meteorological database for four wetland sites in England and Greece. Preliminary results are promising. The SHYLOC software and the coupled hydrological/hydraulic modelling package have been completed and are being applied to the project test sites. There is a correlation between space-borne and ground based measurements of ditch water levels, and water balances are being prepared for two of the wetland sites.

A hydrological model that combined the spatial and temporal distribution of rainfall, suitable infiltration parameters, and appropriate sub-basin unit hydrographs to estimate rainfall excess, transmission losses along stream networks, and downstream runoff was developed. The Wadi El-Arish watershed receives an annual average rainfall of 981.3X10 (super 6) m (super 3) in the rainy season (November-March) of which our model indicates that 938.7X10 (super 6) m (super 3) is the initial upstream loss, 32.5X10 (super 6) m (super 3) is the transmission loss recharging the alluvial aquifers flooring the stream network, and 10.1X10 (super 6) m (super 3) is downstream runoff.

This property of subsurface temperatures is used to examine the groundwater flow pattern at four sites in the Albuquerque basin along the eastern edge of the Rio Grande flood plain. Two sites demonstrate appreciable groundwater flow, although quite different in nature; and two sites demonstrate little if any groundwater movement. The two sites demonstrating groundwater flow are in areas showing vegetation on a Landsat thematic map of the area; one site is located beside a major arroyo drainage. The two sites showing little if any groundwater flow are away from any large drainage structures and show no vegetation on the Landsat thematic map.

Results show ET estimates from the model to be consistent with the magnitudes of measurements at local scales.

The first one is a set of high spatial resolution remote sensing data, allowing the consideration of 100 m size agricultural fields, and the second is a surface energy balance model that retrieves some variables of interest through the spatial variability depicted by the study area. The proposed approach was tested using field measurements on different crops during one year. The comparison showed that the key points of the model gave realistic results and that the energy flux estimates were in agreement with experimental reference measurements.

Activities of the first project stage are presented, emphasizing the common environmental problem of nutrient leaching within two representative basins located in Germany and Austria. The scientific approach is focused on physical parameters describing soil and vegetation cover by means of multiresolution and multi-spectral land-use classifications using Landsat-5 TM and IRS-1C PAN data.

On average, values derived from GOES-East are 18% greater, while those from GOES-West are 9% lower than field measurements. After re-calibration, random differences between hourly satellite estimates and surface observations remained. These were markedly reduced when daily-average values were compared. Root mean square error (RMSE) between the satellite and the surface measurements is lower for the high-resolution satellite estimates than it is for the low-resolution estimates, and there is a noticeable increase in apparent structure with the high-resolution data. Finally, the application of the high-resolution estimates of solar radiation to calculate daily estimates of crop evaporation for wheat and cotton fields is demonstrated.

This has been attributed to the significant differences existing between the radiative and the so-called "aerodynamic" temperature of the surface. Numerous studies have explored ways of accounting for the discrepancies between radiometric and aerodynamic temperatures. Radiometric temperature and surface flux observations collected during the 1999 Southern Great Plains Experiment (SGP99) over four field sites comprising the major land cover types for this region are used to evaluate these approaches. The results suggest correction schemes require site-specific calibration and therefore are not useful for regional applications. A more general approach, which accounts for the main factors affecting radiometric and aerodynamic temperatures and reduces the impact of errors in radiometric temperature observations, is presented.

Longitudinally, the width of the mapped area would be on the order of + or -50 degrees at the Equator, somewhat more at the most northern/southern latitudes. Within the area mapped, very good temporal coverage can be obtained-up to several mappings during the 12 hours per day where the satellite is in the "right" hemisphere. This would be a key capability in relation to disaster management, tectonic mapping and modeling, vegetation and soil moisture mapping, and for operational and semi-operational requirements. A constellation of geosynchronous satellites could provide global coverage.

These techniques allowed us to determine textural alterations of minerals by the organisms, microbial morphology, and elemental distributions in host rock vs organisms and with depth. In addition, we examined the same transect of the same sample by fluorescence microscopy using deep-ultraviolet laser excitation of 224 nm. Our ESEM-EDS results showed that different regions of rock-the outer weathering rind, uncolonised mineral, microorganisms, formerly colonised and weathered mineral-- had unique elemental compositions which corresponded to unique morphological and textural features. Graphical profiles of physiologically vital elements (Ca, Cl, K) by EDS closely matched biomass measurements made of UV-induced fluorescence. The microbial cells, most obvious as filaments, were covered by extracellular polymers ("slime") which served as a site for metal accumulation and formation of fine-grained minerals with a clay-like morphology. These coatings showed a high silicon content. As the amount of biomass trailed off with depth in the rock, microbial filaments were progressively more silicified until only "fossils" were left. Our study allowed us to have a unique insight into processes of mineral dissolution and redistribution of trace elements (i.e., weathering) in a setting where the spatial contact between minerals and biota is maximised relative to other settings such as soils and sediments.

For Mars and Venus, escape of hydrogen to space is widely believed to have led to their present highly oxidized states. Hydrogen escape has usually been ignored for Archean Earth, because water vapor is cold-trapped at the tropopause to a few ppmv, rendering hydrogen escape negligible. However, biogenic methane is not cold trapped. Methane's expected abundance in the Archean, given low oxygen levels, would have been approximately 100-1000 times present, resulting in significant hydrogen escape and irreversible oxidation. After accounting for back-reaction of photosynthetic organic matter with O (sub 2) , the net result of photosynthesis and methanogenesis is CO (sub 2) +2H (sub 2) O -->CH (sub 4) +2O (sub 2) . In the Archean, the kinetic fates of O (sub 2) and CH (sub 4) would be reversed compared to today. Inert CH (sub 4) would have a residence time approximately 10 (super 4) years, whereas reactive O (sub 2) would be lost in approximately days to reduced metamorphic/volcanic gases, and oceanic cations like Fe (super 2+) . Thus before the rise of atmospheric O (sub 2) on early Earth, biogenic methane is widely postulated to have been the greenhouse gas that countered 20-30% lower solar luminosity [e.g., Pavlov et al. (2000) JGR v105, 11981-11990; Rye et al (1995) Nature 378, 603-605]. Calculated Archean CH (sub 4) levels would be approximately 200-3000 ppmv, if the biogenic source were 0.1-1 times present, producing hydrogen escape to space orders of magnitude faster than today. Such hydrogen escape is coupled to photosynthesis and oxidizes the Earth. Photosynthesis splits water into O (sub 2) and hydrogen, hydrogen is transferred to CH (sub 4) by methanogenesis, and hydrogen escape from the upper atmosphere after CH (sub 4) photolysis results in irreversible gain of oxygen (CO (sub 2) +2H (sub 2) O --> CH (sub 4) +2O (sub 2) --> CO (sub 2) +O (sub 2) +4H. Irreversible oxidation is significant ( approximately 10 (super 12) -10 (super 13) mol O (sub 2) yr (super 1) ) and would result in cumulative oxidation of the Earth's crust and associated metamorphic gases. We suggest that this process should not be neglected in attempting to understand the rise of O (sub 2) .

Thermally-driven postdepositional increases in kerogen delta (super 13) C (sub red) were usually minor. Archean delta (super 13) C (sub red) ranges from >-10 to <-60 and exhibits multiple isotopic modes, consistent with a diversity of pathways for carbon assimilation among globally-prominent anaerobic microbial ecosystems. Archean carbonate delta (super 13) C (sub carb) values cluster near 0, consistent with total dominance of the redox balance of the Archean carbon cycle by the mantle, which even today is a major redox buffer. The rise of oxygenic photosynthesis enabled life to obtain additional reducing power by splitting H (sub 2) O. Thus, during the Proterozoic, photosynthetic production rose above the level determined by mantle-derived fluxes of reduced species. Today, chemoautotrophs harvesting energy from hydrothermal emanations synthesize globally at most between 0.2X10 (super 12) and 2X10 (super 12) mol organic C yr (super 1) . In contrast, global photosynthetic productivity is estimated as 9000X10 (super 12) mol C yr (super 1) . During the early Proterozoic, major excursions in delta (super 13) C (sub carb) , and thus in relative sedimentation rates of organics versus carbonates, confirm the global importance of oxygenic photosynthesis by that time. Secular changes in the Proterozoic sedimentary delta (super 13) C (sub red) record are consistent with an increase in the oxidation state of the environment and a transition to global dominance by producers and utilizers of O (sub 2) and SO (sub 4) (super =) . This progressive oxidation was episodic. For example, between 2.2 and 1.9 Ga, crustal and atmospheric reservoirs of O (sub 2) , Fe (super 3+) and SO (sub 4) (super =) increase was relatively rapid and too large to be attributed solely to the declining rate of oxidant consumption by volcanic and hydrothermal reduced species. Additional changes seem required, e.g., in the style of organic sedimentation and preservation. Episodic changes in the carbon cycle and in O (sub 2) levels likely influenced the evolution of Eukarya.

Intrabasinal delta (super 13) C (sub dol) correlation and average delta (super 18) O values of -4ppm (PDB) indicate many Chuar dolomites preserve near-primary delta (super 13) C (sub dol) values. Large-magnitude C-isotope shifts in the Chuar Group resemble those from other mid-Neoproterozoic C-curves. The negative delta (super 13) C (sub org) shift of approximately 11ppm in the upper Chuar Group coincides with Melanocyrillium (vase-shaped microfossil) and a U-Pb date of 742 Ma (ash), which allows regional correlation with the upper Pahrump and Uinta Mountain groups of the western United States, and perhaps with the large negative shift in the upper part (pre-Sturtian) of the global curve of Hill and Walter (2000). C-isotope variability lower in the Chuar Group may correlate with lower parts of regional and global C-curves. There are intriguing dissimilarities between the Chuar and global carbon curves. Typical Chuar delta (super 13) C values (relative to delta (super 13) C (sub carb) ) range from 0 to +12ppm, whereas the global C-curve ranges from -5 to +8ppm. The Chuar Group also shows a pattern of thick stratigraphic intervals with near-zero delta (super 13) C values punctuated by relatively thinner intervals with strongly positive delta (super 13) C values, whereas the global curve shows an opposite pattern. These dissimilarities may be explained by regional/local influences on Chuar seawater chemistry, unconformities within the Chuar Group or within successions comprising the global curve, variable sediment accumulation rates, and/or comparison of C-curves with differing sampling and temporal resolutions. The Chuar Group offers an important mid-Neoproterozoic data set that includes high-resolution C-isotope data in the context of sedimentologic, physical stratigraphic, biostratigraphic, and geochronologic data. Hypotheses that explain the unique Neoproterozoic Earth system require testing by high-resolution interbasinal correlations to demonstrate the synchroneity (or not) of stratigraphic events.

At the highest level there are two sources of information in Earth-science data assimilation, a physical-based prediction model and geophysical observations. The impact of a particular type of observation is dependent on model quality, analysis method, observation quality control, data usage, and system interfaces. This talk will highlight the impact of new observing systems on the quality of assimilated data sets. Of particular interest will be systematic improvements that extend beyond the particular impact that an observing system was designed to address. For instance, ocean-surface wind measurements provide definitive improvement to weather forecasts as well as better estimates of boundary layer processes that are important for trace gas transport. The impact of ocean surface winds, rainfall data, and new sources of temperature and constituent information will be discussed.

Organically preserved microfossils are uncommon, being largely restricted to lower temperature microfacies where permineralization processes are more common. Microelectrode measurements of rapidly mineralizing hot spring mats in Yellowstone have revealed that mat/sinter frameworks retain anomalously high photosynthetic oxygen concentrations (between 3-7 times atmospheric) down to a depth of several centimeters. In these systems, the presence of a slime (exopolymer) matrix appears to play a key role in the retention of photosynthetic oxygen by reducing mat permeability. Thermal spring mats show clear taphonomic contrasts with well-studied laminated mat systems of coastal marine salars in Central Baja. High sulfide concentrations in these rapidly accreting systems is associated with slower rates of organic matter degradation. Early diagenetic mineralization of analogous laminated mat systems in late Proterozoic peritidal environments produced many well documented examples of excellent cellular-level preservation. The high oxygen concentrations observed in rapidly-mineralizing thermal spring mat systems appear to account for the rapid degradation of organic matter that occurs during early diagenesis and is consistent with observations of ancient thermal spring sinter analogs. However, a deeper understanding the taphonomic processes of thermal spring environments will require clarification of the balance between carbon burial and oxidation and a knowledge of the actual processes of organic matter degradation. In theory, high oxygen concentrations should restrict sulfate reduction, while sustaining high rates of aerobic heterotrophy and inorganic oxidation. Future experiments will seek to define the relative contributions of these processes.

Sulfur is common in enzymes and co-enzymes and is an indispensable structural component in many peptides and proteins. Early metabolisms may have been heavily influenced by the abundance of sulfide minerals in hydrothermal systems. Understanding how sulfur became prevalent in biochemical processes and many biomolecules requires knowledge of the reaction properties of sulfur-bearing compounds. We have previously estimated thermodynamic data for thiols, the simplest organic sulfur compounds, at elevated temperatures and pressures. If life began in hydrothermal environments, it is especially important to understand reactions at elevated temperatures among sulfur-bearing compounds and other organic molecules essential for the origin and persistence of life. Here we examine reactions that may have formed amino acids with thiols as reaction intermediates in hypothetical early Earth hydrothermal environments. (There are two amino acids, cysteine and methionine, that contain sulfur.) Our calculations suggest that significant amounts of some amino acids were produced in early Earth hydrothermal fluids, given reasonable concentrations H2, NH3, H2S and CO. For example, preliminary results indicate that glycine activities as high as 1 mmol can be reached in these systems at 100 degrees C. Alanine formation from propanethiol is also a favorable reaction. On the other hand, the calculated equilibrium log activities of cysteine and serine from propanethiol are -21 and -19, respectively, at 100 degrees C. These results indicate that while amino acid formation with thiols as intermediates is favored in some cases, other mechanisms may have been necessary to produce significant amounts of other amino acids. Coupled with our previous results for thiols, these studies imply that sulfur may have been easily incorporated into the organic geochemistry of early Earth hydrothermal systems, leading to its widespread use in biomolecules. Formation of more complex biomolecules in hydrothermal systems may have required sulfur-bearing organic compounds as reaction intermediates.

In order to better understand the mechanisms of silicification and thus improve our search patterns for evidence of fossil microbial life in rocks, a series of laboratory controlled experiments were designed to simulate the silicification of microorganisms. The facultative aerobic bacterial strain Pseudomonas fluorescens and the obligate anaerobic sulphate reducing bacterial strain Desulphovibrio indonensis were exposed to silicifying media. The experiments were designed to obtain information on the influence of exposure time of the biofilms to silica-rich aqueous solutions, as well as to elucidate the effects of ion availability. Biofilms of both bacterial species were exposed to a 1000 ppm silica solution for 4 hours, 24 hours, 1 week, 1 month, 3 months, and 6 months, and also for 1 week to 1000, 3000, and 5000 ppm silica solutions. Subsequent to the silicification processes the bacterial biofilms were analysed using Transmission Electron Microscopy (TEM) in combination with Energy Dispersive X-ray Analysis (EDX). Both bacterial species showed evidence of silicification after only 4 hours in 1000 ppm silica solution, although it emerged that D. indonensis were less prone to silicification. High ion availability resulted in better preservation of cellular detail; the concentration of silica therefore is more important than the duration of exposure to a silicifying agent. Cells became permineralised and no evidence of massive amorphous silica precipitation was observed. High-resolution TEM analyses revealed the presence of nanometer-sized crystallites within the bacterial cells after one week in the 5000 ppm silica solution of possible siliceous nature. The mechanisms of silicification under laboratory-controlled conditions and the implication for silicification in natural environments, the search for early Earth life and possible evidence of extraterrestrial life are discussed.

Two basic approaches to modeling the late glacial climate involve the time slice approach and the sensitivity test approach. The time slice approach attempts to model a particular past climate interval using a set of multiple boundary conditions (forcing parameters), while the sensitivity test approach isolates the effect of one boundary condition at a time for a particular time interval. Examples are given for each approach, including studies of various forcing parameters such as changes in insolation, ice sheets, sea surface temperature (SST), ocean transports, and CO (sub 2) . Despite the use of different atmospheric general circulation models (AGCMs), including the National Center for Atmospheric Research (NCAR), Geophysical Fluid Dynamics Laboratory (GFDL), Goddard Institute for Space Studies (GISS), and European Community Hamburg Model Version 3 (ECHAM3), there are similarities in the various model responses to forcing parameters, such as insolation and land ice at 12,000 B.P. (all dates are given as calendar years, except when stated differently). With other forcing parameters, i.e., SST and sea ice, the results are not comparable from model to model because duplicate experiments have not been made with different models. Recent focus on coupled ocean-atmosphere GCMs provides new tools for exploring ocean-atmosphere links. A key question emerges as to just how important ocean circulation changes are in affecting global late glacial climate changes. Just how important is lowered CO (sub 2) ? How are the Northern and Southern Hemisphere climate responses linked? The iterative process of data-model comparison and the development of new questions are essential to this pursuit.

The distribution of data in separate databases in different countries has however created difficulty for scientists searching for Antarctic-related data. Therefore, the need for Antarctic data management has become a priority. In collaboration with the Joint Committee on Antarctic Data Management (JCADM), NASA's Global Change Master Directory (GCMD) has developed a portal, called the Antarctic Master Directory (AMD), to aid Earth science researchers in the discovery and description of Antarctic data (http://gcmd.nasa.gov/Data/portals/amd/). The AMD accesses a virtual subset of the GCMD database of Earth science-related metadata by filtering metadata records relevant to Antarctica or the Southern Ocean. The AMD portal increases the accessibility to Antarctica data, which are distributed among several National Antarctic Data Centers (NADCs) around the world. Metadata records can be added to the AMD or modified, using a GCMD-customized online metadata-authoring tool.

We made detailed noble gas analyses of each of these phases. The (super 39) Ar- (super 40) Ar age of Monahans light is 4.533+ or -0.006 Ma. Monahans dark and halite samples show greater amounts of diffusive loss of (super 40) Ar and the maximum ages are 4.50 and 4.33 Ga, respectively. Monahans dark phase contains significant concentrations of He, Ne and Ar implanted by the solar wind when this material was extant in a parent body regolith. Monahans light contains no solar gases. From the cosmogenic (super 3) He, (super 21) Ne, and (super 38) Ar in Monahans light we calculate a probable cosmic-ray, space exposure age of 6.0+ or -0.5 Ma. Monahans dark contains twice as much cosmogenic (super 21) Ne and (super 38) Ar as does the light and indicates early near-surface exposure of 13-18 Ma in a H-chondrite regolith. The existence of fragile halite grains in H-chondrites suggests that this regolith irradiation occurred very early. Large concentrations of (super 36) Ar in the halite were produced during regolith exposure by neutron capture on (super 35) Cl, followed by decay to (super 36) Ar in the halite were produced during regolith exposure by neutron capture on (super 35) Cl, followed by decay to (super 36) Ar. The thermal neutron fluence seen by the halite was (2-4) X 10 (super 14) n/cm (super 2) . The thermal neutron flux during regolith exposure was approximately 0.4-0.7 n/cm (super 2) /s. The Monahans neutron fluence is more than an order of magnitude less than that acquired during space exposure of several large meteorites and of lunar soils, but the neutron flux is lower by a factor of < or =5. Comparison of the (super 36) Ar (sub n) / (super 21) Ne (sub cos) ratio in Monahans halite and silicate with the theoretically calculated ratio as a function of shielding depth in an H-chondrite regolith suggests that irradiation of Monahans dark occurred under low shielding in a regolith that may have been relatively shallow. Late addition of halite to the regolith can be ruled out. However, irradiation of halite and silicate for different times at different depths in an extensive regolith cannot be excluded.

Because of the low gradients in the Everglades, vegetation structural characteristics are very important and greatly influence surface water flow and distribution. Vegetation density is being evaluated as an index of surface resistance to flow. Digital multispectral videography (DMSV) has been captured over several sites just before field collection of vegetation data. Linear regression has been used to establish a relationship between normalized difference vegetation index (NDVI) values computed from the DMSV and field-collected biomass and density estimates. Spatial analysis applied to the DMSV data indicates that thematic mapper (TM) resolution is at the limit required to capture land surface heterogeneity. The TM data collected close to the time of the DMSV will be used to derive a regional sawgrass density map. JF - IAHS-AISH Publication AU - Jones, John W A2 - Owe, Manfred A2 - Brubaker, Kaye L.

We found that S has a strong affinity for liquid Fe-Ni-alloy at all the experimental conditions investigated. Partition coefficient of S between liquid Fe-Ni-alloy and liquid silicate (D (sub S) (super LA/LS) ) increases with pressure and decreases with temperature. At the proposed pressure and temperature of core-mantle equilibrium during early Earth differentiation [Li and Agee, 1996; Righter et al., 1997], S is highly siderophile (D (sub S) (super LA/LS) approximately 1000), while Si and O are highly lithophile (D (sub Si) (super LA/LS) , D (sub O) (super LA/LS) < 0.03). Our study suggests that if the core composition was largely established by equilibrium partitioning in a deep magma ocean, then S is the most plausible principle light element in the core.

The measurements are confined in latitude (64.6 degrees -67.2 degrees N) and local time (0321-0418), but their distribution in longitude is fairly uniform. We used least squares spectral analysis to characterize the zonal structure of the atmosphere and constructed longitude-height cross sections of both temperature and geopotential. Zonal variations of temperature exceed 12 K near the surface but are much smaller (2-3 K) at higher altitudes. Zonal variations of geopotential are approximately 200 m throughout the vertical range of the measurements. These patterns of temperature and geopotential appear to be stationary relative to the surface with little day-to-day variation within the 7-sol span of the measurements. We relied heavily on Mars general circulation models (GCMs) for guidance in understanding these data. Stationary planetary waves are responsible for some aspects of the temperature and geopotential fields, particularly at pressures exceeding 100-200 Pa. On the basis of strong similarities between a GCM simulation and the observations, we conclude that the disturbance takes the form of a planetary wave train excited by Alba Patera. The data also include the signature of non-Sun-synchronous thermal tides, which produce a pattern that appears to be stationary when sampled at fixed local time. Comparison between a GCM simulation and the measured geopotential field provides evidence for the presence of the resonantly enhanced, diurnal, wave-1 Kelvin mode.

In this cycle, warmer temperatures speed silicate weathering and carbonate formation, reducing atmospheric CO (sub 2) and thereby inducing global cooling. Over long periods of time, cycling of CO (sub 2) into and out of the mantle also dynamically buffers CO (sub 2) . In the mantle cycle, CO (sub 2) is outgassed at ridge axes and island arcs, while subduction of carbonatized oceanic basalt and pelagic sediments returns CO (sub 2) to the mantle. Negative feedback is provided because the amount of basalt carbonatization depends on CO (sub 2) in seawater and therefore on CO (sub 2) in the air. On the early Earth, processes involving tectonics were more vigorous than at present, and the dynamic mantle buffer dominated over the crustal one. The mantle cycle would have maintained atmospheric and oceanic CO (sub 2) reservoirs at levels where the climate was cold in the Archean unless another greenhouse gas was important. Reaction of CO (sub 2) with impact ejecta and its eventual subduction produce even lower levels of atmospheric CO (sub 2) and small crustal carbonate reservoirs in the Hadean. Despite its name, the Hadean climate would have been freezing unless tempered by other greenhouse gases. Copyright 2001 by the American Geophysical Union.

We use the NASA Ocean Altimeter Pathfinder Project collinear data set and monthly climatic hydrography to restore the dynamical sea level, that which connected with the Black Sea circulation. Two realizations are created from collinear and grid data sets. The Black Sea hydrographic survey data collected by the Cooperative Marine Science Programme for the Black Sea are used for validation of both products. The estimated rms accuracy of the Black Sea dynamical level is about 3 cm. The grid data product is used for the analysis of seasonal and mesoscale variability of the Black Sea level. The observations show that the Black Sea circulation has strong seasonal variation. It attenuates in summer to autumn and intensifies in winter to spring. This variability is accompanied by a western-phase propagation of the sea level. A simple two-layer model of the wind-induced circulation in the rectangular basin provides an interpretation of these results. It is shown that the seasonal variability of the geostrophic circulation is most likely produced by the annual changes of the wind stress curl. The western phase propagation is treated as the radiation of Rossby waves from the eastern coast of the basin. Typical periods of the mesoscale oscillations of the dynamical sea level are estimated from the TOPEX/Poseidon altimeter time series in different parts of the Black Sea by means of a spectral analysis. The strongest mesoscale oscillations have periods of about 120 days and are located in the southeastern part of the basin, where the Rim Current bifurcates, and off the Crimean peninsula, where the Rim Current meanders as a result of the local orography.

Near the end of the hot early phase of star and planet formation, volatile, less refractory materials were transported into the inner solar system as comets and interplanetary dust particles. Once the inner planets had sufficiently cooled, late accretionary infall seeded them with complex organic compounds [Oro, J. (1961) Nature (London) 190, 389-390; Delsemme, A. H. (1984) Origins Life 14, 51-60; Anders, E. (1989) Nature (London) 342, 255-257; Chyba, C. F. & Sagan, C. (1992) Nature (London) 355, 125-131]. Delivery of such extraterrestrial compounds may have contributed to the organic inventory necessary for the origin of life. Interstellar ices, the building blocks of comets, tie up a large fraction of the biogenic elements available in molecular clouds. In our efforts to understand their synthesis, chemical composition, and physical properties, we report here that a complex mixture of molecules is produced by UV photolysis of realistic, interstellar ice analogs, and that some of the components have properties relevant to the origin of life, including the ability to self-assemble into vesicular structures.

This study evaluated several incentive and monitoring mechanisms available to institutions, as well as assignment and background characteristics that previous studies related to performance. Therefore the results of this study suggest ways that institutions may best influence various types of faculty along the dependent variables of this study: the time that faculty devote to teaching per students and a faculty member's use of collaborative learning. To evaluate the incentives, monitoring mechanisms, assignment, and background variables, this study analyzed the National Study of Postsecondary Faculty. This study was limited to an examination of faculty that taught in the nations 2-years institutions during the fall of 1992, and relied upon 7,462 (266,543 weighted) cases for use in this analysis. A combination approach relying upon linear and logistical regression analysis was used to examine faculty time and instructional approach, respectively. A variety of statistical techniques were employed to rely upon the representative nature of the data while correcting for design effects stemming from the sampling framework (Skinner, Holt, & Smith, 1989). The results of this study indicate that there are similarities and differences between adjunct and permanent faculty. Results identified dramatic differences in the time adjunct faculty devoted to teaching per student versus permanent faculty. As expected, results also identified increased faculty workload as a negative influence on the time faculty devoted to teaching and the use of collaborative learning, and more years of experience as an overall positive influence. Specific policies and incentives were also related to increased time devoted to instruction, and included professional development, such as tuition reimbursement and training in teaching, and the use of student outcomes based assessment. These options improved the time devoted to teaching per student, however other factors exerted a negative influence on faculty effort, including a faculty member's doctoral level education and the use of peer evaluations when units assess faculty performance.

However, the impact of climate change and anthropogenic activity on carbon flow is not well known. Sources of organic matter to the Chesapeake Bay sedimentary record of the past 2000+ years were examined using lipid biomarkers and stable isotope analyses. Lipid biomarkers and stable C and N isotopes in surface sediments from Delaware Bay and Chesapeake Bay indicate varying contributions of terrestrial, algal and bacterial organic matter. The sedimentary record of Chesapeake Bay demonstrates source contributions from higher in situ productivity and onset of anoxia in mid-bay waters. Dramatic increases in sedimentary organic carbon from 1-2 percent and 0.7-1.4 percent and shifts in stable C and N isotopes occurred from the 1600s to the 1800s, corresponding to periods of land clearance.

N1 - Last updated - 2016-05-27 ER - TY - JOUR T1 - Implementing a nitrogen-based model for autotrophic respiration using satellite and field observations AN - 18612399; 5493946 AB - The rate of carbon accumulation by terrestrial plant communities in a process-level, mechanistic modeling is the difference of the rate of gross photosynthesis by a canopy (A sub(g)) and autotrophic respiration (R) of the stand. Observations for different biomes often show that R to be a large and variable fraction of A sub(g), ca. 35% to 75%, although other studies suggest the ratio of R and A sub(g) to be less variable. Here, R has been calculated according to the two compartment model as being the sum of maintenance and growth components. The maintenance respiration of foliage and living fine roots for different biomes has been determined objectively from observed nitrogen content of these organs. The sapwood maintenance respiration is based on pipe theory, and checked against an independently derived equation considering sapwood biomass and its maintenance coefficient. The growth respiration has been calculated from the difference of A sub(g) and maintenance respiration. The A sub(g) is obtained as the product of biome-specific radiation use efficiency for gross photosynthesis under unstressed conditions and intercepted photosynthetically active radiation, and adjusted for stress. Calculations have been done using satellite and ground observations for 36 consecutive months (1987-1989) over large contiguous areas (ca. 10 super(5) km super(2)) of boreal forests, cropland, temperate deciduous forest, temperate grassland, tropical deciduous forest, tropical evergreen forest, tropical savanna, and tundra. The ratio of annual respiration and gross photosynthesis, (R/A sub(g)), is found to be 0.5-0.6 for temperate and cold adopted biome areas, but somewhat higher for tropical biome areas (0.6-0.7). Interannual variation of the fluxes is found to be generally less than 15%. Calculated fluxes are compared with observations and several previous estimates. Results of sensitivity analysis are presented for uncertainties in parameterization and input data. It is found that uncertainty in determining maintenance respiration for tropical biomes is such that R/A sub(g) for these biomes could be similar to that for temperate biomes.

Starting in 1995 the NASA Arctic Ice Mapping (AIM) group from the NASA Goddard Space Flight Center's Wallops Flight Facility began mapping beaches as a part of technology enhancement activities or warm-up missions prior to conducting elevation measurements of the Greenland Ice Sheet as part of NASA's Global Climate Change program. During the ensuing years, in conjunction with the NOAA Coastal Services Center and the USGS Center for Coastal Geology, the program has expanded to provide a baseline survey of 1100 km of the US East Coast and 800 km of the Gulf coast. Of particular interest is a before-and-after survey of 1000 km of West Coast shoreline associated with the 1997-98 El Nino winter storm events. The resulting data are compared to surface surveys using standard techniques. The goal of these projects is to make these measurements to an accuracy of 10-15 cm. Most of the data have been collected using NAAA's Twin Otter aircraft using NASA's Airborne Topographic Mapper (ATM), a scanning laser system. The necessary high accuracy vertical as well as horizontal positioning are provided by Global Positioning System (GPS) receivers located both on board the aircraft and at a fixed site.

The SeaWiFS mission is designed to provide near daily global coverage of the world's oceans and coastlines. Since its launch on August 1, 1997, it has provided an abundance of data from coastal areas. Unlike CZCS, the SeaWiFS instrument has a bilinear gain sensitivity, which permits imaging of the land, ocean, and atmosphere simultaneously. SeaWiFS data, therefore, provide a resource for monitoring complex land/water boundary systems such as coastlines, estuaries and lakes. In addition, SeaWiFS provides daily global coverage at eight wavelengths in the visible and near infrared, plus a swift turn around time for the data products. The SeaWiFS Project provides a free software package, the SeaWiFS Data Analysis System (SeaDAS), which is easy to use and specifically designed for processing SeaWiFS measurements. SeaDAS also provides the capability to display and manipulate data from other satellite instruments, including AVHRR, CZCS, MODIS, MOS, OCTS and POLDER. Recently, the SeaWiFS Project mounted a reprocessing effort to improve the quality of the data set. One result of this reprocessing was an improvement in the SeaWiFS coastal data. The new processing methods increase the number and quality of coastal retrievals, making coastal data more readily available and accurate. To date, SeaWiFS data have been used for a variety of coastal applications. Harmful algal blooms, which often affect coastal areas, have been monitored using SeaWiFS data. In addition, coccolithophore blooms off the coast of Alaska, that impact salmon fisheries in the region, have been observed and monitored. Over the past year, SeaWiFS data have been applied to several instances of flood monitoring; last winter in Mozambique, and last September after hurricane Floyd swept through the U.S. east coast. Contaminated estuaries and other areas affected by flooding can easily be distinguished in SeaWiFS imagery, assisting aid and rebuilding efforts, and highlighting where mitigation measures can be applied to minimize such damage in the future.

The region regularly experiences sea-breeze fronts and rainfall-induced outflow boundaries. The focus of this study is convection associated with the commonly occurring convergence zone established by the interaction of the sea-breeze front and an outflow boundary. Previous studies have investigated mechanisms primarily affecting storm initiation by such convergence zones. Few have focused on rainfall morphology, yet these storms contribute a significant amount of precipitation to the annual rainfall budget. Low-level convergence and midtropospheric moisture have been shown to be correlated with rainfall amounts in Florida. Using 2D and 3D numerical simulations, the roles of low-level convergence and midtropospheric moisture in rainfall evolution are examined. The results indicate that area- and time-averaged, vertical moisture flux (VMF) at the sea-breeze front-outflow convergence zone is directly and linearly proportional to initial condensation rates. A similar relationship exists between VMF and initial rainfall. The VMF, which encompasses depth and magnitude of convergence, is better correlated to initial rainfall production than surface moisture convergence. This extends early observational studies that linked rainfall in Florida to surface moisture convergence. The amount and distribution of midtropospheric moisture affects how much rainfall associated with secondary cells develop. Rainfall amount and efficiency varied significantly over an observable range of relative humidities in the 850-500-mb layer even though rainfall evolution was similar during the initial or "first cell" period. Rainfall variability was attributed to drier midtropospheric environments inhibiting secondary cell development through entrainment effects. Observationally, a 850-500-mb moisture structure exhibits wider variability than lower-level moisture, which is virtually always present in Florida. A likely consequence of the variability in 850-500-mb moisture is a stronger statistical correlation to rainfall as noted in previous observational studies. The VMF at convergence zones is critical in determining rainfall in the initial stage of development but plays a decreasing role in rainfall evolution as the system matures. The midtropospheric moisture (e.g., environment) plays an increasing role in rainfall evolution as the system matures. This suggests the need to improve measurements of depth and magnitude of convergence and midtropospheric moisture distribution. It also highlights that the influence of the environment needs to be better represented in convective parameterizations of larger-scale models to account for entrainment effects.

The products include 25 observational (satellite based), four model, and two climatological products. The results of the intercomparison indicate a very large range (factor of 2 or 3) of values when all products are considered. The range of values is reduced considerably when the set of observational products is limited to those considered quasi-standard. The model products do significantly poorer in the Tropics, but are competitive with satellite-based fields in midlatitudes over land. Over ocean, products are compared to frequency of precipitation from ship observations. The evaluation of the observational products points to merged data products (including rain gauge information) as providing the overall best results.

The hydrometeor profile retrieval algorithm presented here exploits it to obtain an approximation of a radiative transfer model, which allows relatively simple inversion. The atmosphere within the FOV is treated as a combination of horizontally homogeneous domains. Assuming that one of known "basic" hydrometeor profiles occurs in each domain, the inverse problem is reduced to a determination of "beamfilling coefficients." The online procedure includes determination of beamfilling coefficients and a footprint-averaged hydrometeor profile as a linear combination of "basic" ones. Off-line procedures involve the selection of a minimum number of necessary "basic" brightness temperature vectors and correction of "basic" hydrometeor profiles to provide the best retrieval accuracy for a given cloud/radiative simulation. The performance of the algorithm is tested for both numerical simulations and TRMM/TMI data. Numerical simulation has allowed a comparison of the information content of radiometer measurements from SSM/I, TMI, and the future AMSR. The effectiveness of the algorithm is being tested for rain water integral and rain rate retrievals from TRMM TMI measurements.

The plan envisions an improved TRMM-like satellite and a constellation of eight satellites carrying passive microwave radiometers to provide global rainfall measurements at 3-h intervals. The success of this concept relies on the merits of rainfall estimates derived from passive microwave radiometers. This article offers a proof-of-concept demonstration of the benefits of using rainfall and total precipitable water (TPW) information derived from such instruments in global data assimilation with observations from the TRMM Microwave Imager (TMI) and two Special Sensor Microwave/Imager (SSM/I) instruments. Global analyses that optimally combine observations from diverse sources with physical models of atmospheric and land processes can provide a comprehensive description of the climate systems. Currently, such data analyses contain significant errors in primary hydrological fields such as precipitation and evaporation, especially in the Tropics. It is shown that assimilating the 6-h-averaged TMI and SSM/I surface rain rate and TPW retrievals improves not only the hydrological cycle but also key climate parameters such as clouds, radiation, and the upper-tropospheric moisture in the analysis produced by the Goddard Earth Observing System Data Assimilation System, as verified against radiation measurements by the Clouds and the Earth's Radiant Energy System instrument and brightness temperature observations by the Television Infrared Observational Satellite Operational Vertical Sounder instruments. Typically, rainfall assimilation improves clouds and radiation in areas of active convection, as well as the latent heating and large-scale motions in the Tropics, while TPW assimilation leads to reduced moisture biases and improved radiative fluxes in clear-sky regions. Ensemble forecasts initialized with analyses that incorporate TMI and SSM/I rainfall and TPW data also yield better short-range predictions of geopotential heights, winds, and precipitation in the Tropics. These results were obtained using a variational procedure based on a 6-h time integration of a column model of moist physics with prescribed dynamical and other physical tendencies. The procedure estimates moisture tendency corrections at observation locations by minimizing the least square differences between the observed TPW and rain rates and those generated by the column model over a 6-h analysis window. These tendency corrections are then applied during the assimilation cycle to compensate for errors arising from both initial conditions and deficiencies in model physics. Our results point to the importance of addressing deficiencies in model physics in assimilating data types such as precipitation, for which the forward model based on convective parameterizations may have significant systematic errors. This study offers a compelling illustration of the potential of using rainfall and TPW information derived from passive microwave instruments to significantly improve the quality of four-dimensional global datasets for climate analysis and weather forecasting applications.

A new satellite index of this deep convective activity is based upon measurements of large ice particles in the upper portions of tropical convective complexes. This 20-year record reveals a strong signal of the El Nino Southern Oscillation (ENSO), with 10 to 15% upward (downward) swings in the deep convective index during El Nino (La Nina). Warming of tropical sea surface temperatures (SST), whether from anthropogenically-produced greenhouse gases or natural climate variability, is expected to be associated with more convective overturning of the atmosphere. While other tropical precipitation climatologies vary dramatically in their support of this relationship, the present deep convective ice (DCI) index shows a strong correlation between interannual variations of tropical convection and SST.

Purpose: In this case report, we examined the effect of a similar exercise protocol 24 h before a Shuttle landing on the orthostatic responses of four crewmembers (EX) after spaceflights of 8-14 d. Four additional crewmembers (CON) served as controls and did not perform exercise during the final day of the flight. Methods: Each crewmember performed a 10-min stand test approximately 10 d before launch (L-10) and within 1-2 h of landing (R+0). Cardiac stroke volume was measured (Doppler ultrasound) supine and during each min of standing for three EX and three CON subjects. Results: Preflight, all crewmembers completed the stand test and each group had similar heart rate and blood pressure responses. Postflight, all subjects also completed the 10-min stand test. Each group had similarly elevated supine and standing heart rates, elevated diastolic and mean arterial blood pressures, and reduced pulse pressures compared to L-10. However, postflight cardiac output, mean plus or minus SEM, (EX: 4.5 plus or minus 0.6 L times min super(-1); CON: 3.1 plus or minus 0.3 L times min super(-1)) and stroke volume (EX: 43 plus or minus 7 mL times beat; CON: 30 plus or minus 6 mL times beat) were higher after 10 min standing in the EX subjects compared to CON subjects. Conclusions: For these four crewmembers, maximal exercise performed 24 h before landing may have helped maintain stroke volume but did not maintain heart rate and blood pressure responses during standing compared to preflight.

Spreading under their own weight, they flow seaward, channeled along preferred routes by the shape or composition of the underlying bedrock. Though we don't know why, some ice streams flow rapidly within slower-moving ice in Greenland and Antarctica. Glaciers exist on all continents except Australia, and at high enough elevations, they can be found even at the equator. Many are melting as global temperatures rise, but about 99% of glacier ice is in Greenland and Antarctica, where it is partly protected from global warming by low temperatures. Nevertheless, the coastal ice sheet in Greenland has thinned recently for unknown reasons, and we still don't know whether the far larger Antarctic ice sheet is growing or shrinking.

We have used vegetation greenness estimates from satellite images as inputs to a terrestrial ecosystem production model. This carbon allocation model generates new estimates of regional aboveground vegetation biomass at 8-km resolution. The modeled biomass product is then combined for the first time with fire pixel counts from the advanced very high-resolution radiometer (AVHRR) to overlay regional burning activities in the Amazon. Results from our analysis indicate that carbon emission estimates from annual region-wide sources of deforestation and biomass burning in the early 1990s are apparently three to five times higher than reported in previous studies for the Brazilian Legal Amazon, i.e., studies which implied that the Legal Amazon region tends toward a net-zero annual source of terrestrial carbon. In contrast, our analysis implies that the total source fluxes over the entire Legal Amazon region range from 0.2 to 1.2 Pg C yr super(-1), depending strongly on annual rainfall patterns. The reasons for our higher burning emission estimates are (1) use of combustion fractions typically measured during Amazon forest burning events for computing carbon losses, (2) more detailed geographic distribution of vegetation biomass and daily fire activity for the region, and (3) inclusion of fire effects in extensive areas of the Legal Amazon covered by open woodland, secondary forests, savanna, and pasture vegetation. The total area of rainforest estimated annually to be deforested did not differ substantially among the previous analyses cited and our own.

Evaluation of biological and environmental factors determining variability of RUE for daily total gross photosynthesis within and among species suggests a biophysically based approach for estimating daily total gross photosynthesis using satellite and ancillary data. Calculations have been done using leaf photosynthesis and canopy characteristics derived from field measurements for six cultivated herbaceous and 12 uncultivated (herbaceous and needle leaf and broadleaf woody) species, and mixed species stands of temperate deciduous forest and tropical moist and dry forests. These data are for 65 canopies, divided about equally between cultivated and uncultivated species, and the leaf area index varies between 0.6 and 9.5. A model for instantaneous canopy photosynthesis, considering sunlit and shaded leaves, variation of maximum rate of leaf photosynthesis within the canopy, and a solution of the radiative transfer equation for propagation of direct and diffuse PAR, is numerically integrated in space (angular variation of radiances and depth within the canopy) and time (diurnal variation) to obtain daily total gross photosynthesis and IPAR for varied incident irradiances. The results show that the maximum rate of leaf photosynthesis and magnitudes of direct and diffuse irradiance incident on the canopy are the major factors determining RUE for unstressed conditions. Also, while woody species on the average have lower RUE, they are found to utilize diffuse radiation more efficiently than cultivated species. Comparison of calculated RUE with observations for 10 cultivated species in varied environment gave differences of -23% to +11% for individual species, but aggregately they have almost equal coefficient of variation ( similar to 25%) and their averages differ by -6% (underestimation). Monthly and annual gross photosynthesis determined using satellite and ancillary data are obtained for rain forest (in Brazil), boreal forest (in Canada), and cropland (in the United States). Annual photosynthesis calculated using satellite data for the three biomes differed from that determined from field measurements by -29% to +15%, averaging to +6%. The above error estimates for RUE and photosynthesis are obtained without calibrating any model parameter.

The rainfall estimate for a given map grid box is subject to both remote sensing error and, especially in the case of low-orbiting satellites, sampling error due to the limited number of observations of the grid box provided by the satellite. A simple model of rain behavior predicts that rms random error in grid-box averages should depend in a simple way on the local average rain rate, and the predicted behavior has been seen in simulations using surface rain gauge and radar data. This relationship is examined using Special Sensor Microwave Imager (SSM/I) satellite data obtained over the western equatorial Pacific during the Tropical Ocean and Global Atmosphere Coupled Ocean-Atmosphere Response Experiment. Rms error inferred directly from SSM/I rainfall estimates is found to be larger than was predicted from surface data and to depend less on local rain rate than was predicted. Preliminary examination of Tropical Rainfall Measuring Mission (TRMM) microwave estimates shows better agreement with surface data. A simple method of estimating rms error in satellite rainfall estimates is suggested, based on quantities that can be computed directly from the satellite data.
