TY - JOUR T1 - Green-light supplementation for enhanced lettuce growth under red- and blue-light-emitting diodes. AN - 67272520; 15770792 AB - Plants will be an important component of future long-term space missions. Lighting systems for growing plants will need to be lightweight, reliable, and durable, and light-emitting diodes (LEDs) have these characteristics. Previous studies demonstrated that the combination of red and blue light was an effective light source for several crops. Yet the appearance of plants under red and blue lighting is purplish gray making visual assessment of any problems difficult. The addition of green light would make the plant leave appear green and normal similar to a natural setting under white light and may also offer a psychological benefit to the crew. Green supplemental lighting could also offer benefits, since green light can better penetrate the plant canopy and potentially increase plant growth by increasing photosynthesis from the leaves in the lower canopy. In this study, four light sources were tested: 1) red and blue LEDs (RB), 2) red and blue LEDs with green fluorescent lamps (RGB), 3) green fluorescent lamps (GF), and 4) cool-white fluorescent lamps (CWF), that provided 0%, 24%, 86%, and 51% of the total PPF in the green region of the spectrum, respectively. The addition of 24% green light (500 to 600 nm) to red and blue LEDs (RGB treatment) enhanced plant growth. The RGB treatment plants produced more biomass than the plants grown under the cool-white fluorescent lamps (CWF treatment), a commonly tested light source used as a broad-spectrum control.

The "Teeka" and "Duffers" trenches were located along a 1.4-km-long, 1-to 4-m-high, northwest-trending, southwest-facing, topographic scarp recognized from Airborne Laser Swath Mapping. Glaciomarine drift exposed in the trenches reveals evidence of about 95 to 150 cm of vertical and 200 to 220 cm of left-lateral slip in the Teeka trench. Radiocarbon ages from a buried soil A horizon and overlying slope colluvium along with the historical record of earthquakes suggest that this faulting occurred 100 to 400 calendar years B.P. (A.D. 1550 to 1850). In the Duffers trench, 370 to 450 cm of vertical separation is accommodated by faulting ( approximately 210 cm) and folding ( approximately 160 to 240 cm), with probable but undetermined amounts of lateral slip. Stratigraphic relations and radiocarbon ages from buried soil, colluvium, and fissure fill in the hanging wall suggest the deformation at Duffers is most likely from two earthquakes that occurred between 100 to 500 and 1100 to 2200 calendar years B.P., but deformation during a single earthquake is also possible. For the two-earthquake hypothesis, deformation at Teeka trench in the first event involved folding but not faulting. Regional relations suggest that the earthquake(s) were M> or = approximately 6.7 and that offshore rupture may have produced tsunamis. Based on this investigation and related recent studies, the maximum recurrence interval for large ground-rupturing crustal-fault earthquakes in the Puget Lowland is about 400 to 600 years or less.

To understand lacustrine carbon and nitrogen cycling in this end-member ecosystem, and to define paleolimnological proxies for ice-covered lakes, we measured the stable carbon and nitrogen isotopic composition of particulate organic matter (POM) and benthic organic matter (BOM) within the lakes of Taylor Valley. The delta (super 13) C compositions of seasonally ice-free edges of the lakes (moats) are enriched relative to under-ice organic matter. Thus, the organic carbon isotopic composition of buried sediments may be a proxy for sample position within the lake. In the moats, delta (super 13) C values are governed by limited CO (sub 2) diffusion across benthic cyanobacterial cell membranes. During a high glacial melt (2001-2002) season, both delta (super 13) C (sub POM) and delta (super 13) C (sub BOM) in the moats were more depleted than during previous low melt years. We propose that this occurred in response to higher [CO (sub 2) ] (sub (aq)) and/or reduced growth rates resulting from turbidity-induced light limitation. (mod. journ. abst.)

Based on this link, Ruddiman [2003] suggested that an anthropogenic source of methane must have been present after 5 kyr BP in order to prevent concentrations from declining as insolation decreased through the Holocene. We conclude however, that since precessional forcing does not explain the large glacial-interglacial excursions, the component of methane variability associated with precession is significantly smaller than assumed by Ruddiman [2003] . The implied decrease from 10 kyr BP to the present associated with precession alone is 60 ppbv or less. (mod. journ. abst.)

The promise is to achieve a sub-microgal accuracy that will define continental mass variations involving large-scale hydrology. With this in mind, we examine the time varying gravity field over central Europe using a limited number of high quality ground-based superconducting gravimeter stations within the Global Geodynamics Project (GGP). Our purpose is to see whether there are coherent signals between the individual stations and to compare the regional component with that predicted from models of continental hydrology. The results are encouraging. We have found, using empirical orthogonal eigenfunctions of the gravity data that a clear annual signal is present that is consistent in phase (low amplitudes in summer) and amplitude (1-3 microgal) with that determined from a large-scale model of land water in connection with global climate modeling. More work is required to define how the gravity field is related to large-scale soil moisture and other mass variations, and we have yet to compare our results to the latest satellite-derived data.

The relative contributions of the far infrared, middle infrared, and windows spectral regions to the total longwave flux densities have been established. The approximate qualitative description of the meridional distributions of the zonal averages gave us a detailed insight into the role of the less explored far infrared spectral region. We demonstrate that on a global scale, the far infrared contribution to the clear-sky normalized greenhouse factor is significantly increasing toward the polar regions. Accurate computation of the transmitted and re-emitted part of the outgoing longwave radiation showed that in the far infrared the normalized upward atmospheric emittance increases poleward. This phenomenon is the direct consequence of the downward shift of the peak of the weighting functions in the strongly absorbing opaque spectral regions. The clear-sky total longwave terrestrial flux transmittance seems to be well correlated with the far infrared flux transmittance, which implies the possibility of inferring total longwave flux densities solely from far infrared observations. The zonal averages of the total normalized atmospheric upward emittances are almost independent of the water vapor column amount, they have no meridional variation, and they are constantly about fifty percent of the surface upward flux density, an indication, that the gray atmosphere in the IR is in radiative equilibrium. The meridional distribution of the greenhouse temperature change and its dependence on the atmospheric water vapor content were also evaluated. Solving the Schwarzschild-Milne equations for the bounded atmosphere the infrared atmospheric transfer and greenhouse functions were derived. The theoretically predicted greenhouse effect in the clear atmosphere is in perfect agreement with simulation results and measurements.

Half of the increase was from higher summer melting, with the rest caused by velocities of some glaciers exceeding those needed to balance upstream snow accumulation. Velocities of one large glacier almost doubled between 1997 and 2003, resulting in net loss from its drainage basin by about 20 km super(3) of ice between 2002 and 2003.

This study uses all of the well-centered overflights of tropical cyclones from 1998 to 2003 seen by the TRMM Precipitation Radar. The chance of intensification increases when one or more extremely tall convective towers exist in the tropical cyclone's eyewall. We define an extremely tall convective tower as a convective cell with a 20 dBZ reflectivity signal that reaches an altitude of at least 14.5 km. In addition, we adapt this radar technique for use with more plentiful infrared and passive microwave data.

It reports on methods of linking climate change scenarios with hydrologic, agricultural, and planning models to study water availability for agriculture under changing climate conditions, to estimate changes in ecosystem services, and to evaluate adaptation strategies for the water resources and agriculture sectors. The models are applied to major agricultural regions in Argentina, Brazil, China, Hungary, Romania, and the US, using projections of climate change, agricultural production, population, technology, and GDP growth. For most of the relatively water-rich areas studied, there appears to be sufficient water for agriculture given the climate change scenarios tested. Northeastern China suffers from the greatest lack of water availability for agriculture and ecosystem services both in the present and in the climate change projections. Projected runoff in the Danube Basin does not change substantially, although climate change causes shifts in environmental stresses within the region. Northern Argentina's occasional problems in water supply for agriculture under the current climate may be exacerbated and may require investments to relieve future tributary stress. In Southeastern Brazil, future water supply for agriculture appears to be plentiful. Water supply in most of the US Cornbelt is projected to increase in most climate change scenarios, but there is concern for tractability in the spring and water-logging in the summer. Adaptation tests imply that only the Brazil case study area can readily accommodate an expansion of irrigated land under climate change, while the other three areas would suffer decreases in system reliability if irrigation areas were to be expanded. Cultivars are available for agricultural adaptation to the projected changes, but their demand for water may be higher than currently adapted varieties. Thus, even in these relatively water-rich areas, changes in water demand due to climate change effects on agriculture and increased demand from urban growth will require timely improvements in crop cultivars, irrigation and drainage technology, and water management.

Such trace gas reductions may allow stabilization of atmospheric CO sub(2) at an achievable level of anthropogenic CO sub(2) emissions, even if the added global warming constituting dangerous anthropogenic interference is as small as 1 degree C. A 1 degree C limit on global warming, with canonical climate sensitivity, requires peak CO sub(2) ~ 440 ppm if further non-CO sub(2) forcing is +0.5 W/m super(2), but peak CO sub(2) ~ 520 ppm if further non-CO sub(2) forcing is -0.5 W/m super(2). The practical result is that a decline of non-CO sub(2) forcings allows climate forcing to be stabilized with a significantly higher transient level of CO sub(2) emissions. Increased "natural" emissions of CO sub(2), N sub(2)O, and CH sub(4) are expected in response to global warming. These emissions, an indirect effect of all climate forcings, are small compared with human-made climate forcing and occur on a time scale of a few centuries, but they tend to aggravate the task of stabilizing atmospheric composition.

Effective g-factors for four OH lines near 3046 cm super(-1) (in the 1-0 band) were obtained from simultaneous detections of OH and H sub(2)O. The measured spatial distribution of this OH "quadruplet" traces that of H sub(2)O, as expected if the excited OH is produced directly by water photolysis. These results establish OH prompt emission as an alternative (and convenient) proxy for water in comets. Possible limitations to the approach are discussed. Extension to other OH multiplets in the L band will permit direct comparison with theoretical models for the rotational population distribution of the free OH radicals produced by H sub(2)O photolysis in cometary atmospheres.

Normal human skin fibroblasts were irradiated with heavy-ion beams, such as carbon- (290 MeV/u and 135 MeV/u), neon- (230 MeV/u and 400 MeV/u), silicon- (490 MeV/u) and iron- (500 MeV/u) ion beams, generated by Heavy Ion Medical Accelerator in Chiba (HIMAC) at national Institute of Radiological Sciences (NIRS). Mutation induction in hprt locus was detected to measure 6-thioguanine resistant colonies and deletion spectrum of exons was analyzed by multiplex PCR. The LET-RBE curves of mutation induction for carbon- and neon-ion beams showed a peak around 75 keV/micrometers and 155 keV/micrometers, respectively. On the other hand, there observed no clear peak for silicon-ion beams. The deletion spectrum of exons was different in induced mutants among different ion species. These results suggested that quantitative and qualitative difference in mutation occurred when using different ion species even if similar LET values.

AN - 67286166; 15858360 AB - To perform experiments in microgravity environment, there should be many difficulties compared with the experiments on ground. JAXA (Japan Aerospace Exploration Agency) has developed various experiment facilities to perform life science experiments in space, such as Cell Culture Kit, Thermo Electric Incubator, Free Flow Electrophoresis Unit, Aquatic Animal Experiment Unit, and so on. The first experiment facilities were flown on Spacelab-J mission in 1992, and they were improved and modified for the 2nd International Microgravity Laboratory (IML-2) mission in 1994. Based on these experiences, some of them were further improved and flown on another missions. These facilities are continuously being improved for the International Space Station use, where high level functions and automatic operations will be required.

AN - 67285911; 15858384 AB - A single cell irradiation system has been developed at JAERI-Takasaki to study radiobiological processes in single-ion-hit mammalian cells and bystander cells, in ways that cannot be achieved using conventional broad field exposures. Individual mammalian cultured cells are irradiated in the atmosphere on the cell dish, the bottom of which is made of ion-track-detector CR-39, with a single or defined numbers of 13.0 MeV/amu 20Ne and 11.5 MeV/amu 40Ar ions. Targeting and irradiation of the cells are performed automatically at the on-line microscope of the microbeam apparatus according to the positional data of the target cells obtained at the off-line microscope before irradiation. Using this system, Chinese hamster ovary (CHO-K1) cells were irradiated with counted number of 20Ne and 40Ar ions. Thereafter, the growth of the cells was observed individually and repeatedly during post-irradiation incubation. The cells hit by a single 40Ar ion on their nucleus showed strong growth inhibition. Meanwhile, the cells in the irradiated dish but not hit by the ion (bystander cells) showed limited cell growth. This might be a bystander effect caused by heavy ion hit cell co-existing in the same dish.

AN - 67285892; 15900637 AB - One of the important concerns for astronauts in space is cancer risk associated with cosmic radiation, including heavy particle ions. But little information on cancer risk is available. We investigated the effect of carbon ions on life span shortening and tumor induction in B6C3F1 mice. The mice were exposed weekly to 0.4 and 2.0 Gy whole-body carbon-ion- or X-ray-irradiation for 4 consecutive weeks. The spectrum of induced tumors varied depending on the dose. The cause of death was thymic lymphomas and liver tumors at high and low dose, respectively. The life span shortening by X-rays was proportional to dose, while carbon ions produced a convex upward relationship. The relative biological effectiveness for the 50% life span shortening was about 1.4. The large effect of carbon ions encourages the study on tumor induction at low doses in the space.

In this study, we examined whether the modulating activity of serum factors on cell mutability was changed in seventeen volunteers subjected to BR. For comparison, serum was comparatively obtained from seven volunteers who experienced the parabolic flight (PF). Cultured human cells were treated with serum and then irradiated with UV or X-ray. Mutagenicity was estimated by identification of K-ras codon 12 base substitution mutation, following PCR and differential dot-blot hybridization. Modulating activity was detected in one sample from each of post-BR and post-PF serum.

We confirmed the formation of complex organic compounds that contained amino acid precursors from a mixture of carbon monoxide (or methanol), ammonia and water by radiation or UV. Molecular weights of the complex organics were several thousands. Stability of the complex precursors was studied. When free amino acids were irradiated with gamma rays or synchrotron radiation, they easily decomposed. The complex precursors were, however, much more stable than free amino acid against irradiation. We propose to examine the formation and alteration of amino acid precursors in space by using exposed facility of ISS.

The applied dose varied from 0.05 Gy up to 2.0 Gy. The subsequent biological effects were evaluated by an induction of apoptosis and neuron survival focusing on the dependencies of the animal strains, SCID, B6, B6C3F1, C3H, used for brain cell culture, SCID was the most sensitive and C3H the least sensitive to particle radiation as evaluated by 10% apoptotic criterion. The LET dependency was compared with using SCID and B6 cells exposing to different ions (H, C, Ne, Si, Ar, and Fe). Although no detectable LET dependency was observed in the high LET (55-200 keV/micrometers) and low dose (<0.5 Gy) regions. The survivability profiles of the neurons were different in the mouse strains and ions.

AN - 67284209; 15858345 AB - We examined the potential contribution of irradiated medium on the bystander effect using custom made double-mylar stainless steel rings. Exponentially growing Human-hamster hybrid (AL) cells were plated on either one or both sides of double-mylar dishes 2-4 days before irradiation. One side (with or without cells) was irradiated with alpha particles using the track segment mode of a 4 MeV Van de Graaff accelerator at the Radiological Research Accelerator Facilities of Columbia University. Since alpha particles can only traverse a very limited distance, cells plated on the other side of a medium-filled mylar dish will not be irradiated by the alpha particles. The results of chromosomal aberrations on un-irradiated target cells that were attached to the top mylar layer indicate that the number of chromatid-type aberrations was higher when there was a bottom layer of cells in the medium filled chambers than just medium alone. Furthermore, when transferring the medium from these cell-irradiated dishes to fresh AL cultures, chromatid-type aberrations were produced in the un-irradiated fresh cells. In contrast, medium irradiated in the absence of cells had no effect on chromatid aberrations. These results suggest that certain modulating factors secreted from the irradiated cells on the bottom mylar layer into the medium, induce chromatin damage in the un-irradiated, bystander cells.

AN - 67283224; 15858379 AB - Eker rat known as a model of hereditary renal carcinoma (RC) is an example of Mendelian dominantly inherited predisposition to a specific cancer in experimental animals. We investigate the effects of simulated space radiation on carcinogenesis using HIMAC. We estimated RBE from the Eker rats exposed to the heavy-ions, C (290 MeV/u) and Fe (500 MeV/u) ions, comparing to the effects of X-ray irradiation. Pregnant rats were exposed to C and Fe ions and X-rays with a single dose of 1 Gy, 2 Gy, 3 Gy on day 19 of gestation. The offspring were sacrificed at 8 weeks of age. We evaluated organ weights and tumor genesis. The weights of thymus, lung, liver, spleen were found to be no difference from the control at 1 Gy irradiation but 50% decrease at 3 Gy irradiation. We found in the irradiated animal that kidney, brain and testis were very sensitive organs of which the weight decreased to approximately 80% at 1 Gy and to 40% at 3 Gy irradiations. Based on the dose-response relationship of the radiation-induced carcinoma, averaged RBE ware calculated to be 1.1 for C-ion, 1.6 for Fe-ion.

AN - 67283102; 15858344 AB - There has been a recent upsurge of interest in radiation-induced adaptive response and bystander effect, which are specific modes in stress response to low-dose/low-dose rate radiation. Recently, we found that the accumulation of iNOS in wtp53 celIs was induced by chronic irradiation with gamma rays followed by acute irradiation with X-rays, but not by each one, resulting in an increase in nitrite concentrations of medium. It is suggested that the accumulation of iNOS may be due to the depression of acute irradiation-induced p53 functions by pre-chronic irradiation. In addition, we found that the radiosensitivity of wtp53 cells against acute irradiation with X-rays was reduced after chronic irradiation with gamma rays. This reduction of radiosensitivity of wtp53 cells was nearly completely suppressed by the addition of NO scavenger, carboxy-PTIO to the medium. This reduction of radiosensitivity of wtp53 cells is just radiation-induced adaptive response, suggesting that NO-mediated bystander effect may considerably contribute to adaptive response induced by radiation.

AN - 67282361; 15858346 AB - We have just started the basic study to detect the genetic alterations at chromosome level as a result of radioadaptive response. The assay system is based upon the analysis of loss of heterozygosity (LOH) induced in human lymphoblastoid cell TK6, which were pre-irradiated with low-doses of ionizing radiation (IR) before the challenging irradiation. In our previous study, this analysis was shown to be very sensitive to IR because the radiation-specific hemizygous LOHs (interstitial deletions) were observed after 10 cGy of IR (X-rays or accelerated carbon-ion beam). Here, we would like to introduce our plan how to detect the changes in such radiation-specific LOH patterns by the pre-irradiation of TK6. If we succeed the detection, the radioadaptation assay system can be used for elucidating the biological effects of low-doses of space ionizing radiation. In addition, we are also considering the modification of assay system by introducing the site-specific chromosome breakage (DNA double-strand break) instead of challenging IR. Furthermore, the preliminary results of the experiments using frozen TK6 cells for the preparation of ISS experiments.

AN - 67210566; 15644352 AB - Composite materials that can serve as both effective shielding materials against cosmic-ray and energetic solar particles in deep space, as well as structural materials for habitat and spacecraft, remain a critical and mission enabling component in mission planning and exploration. Polyethylene is known to have excellent shielding properties due to its low density, coupled with high hydrogen content. Polyethylene-fiber reinforced composites promise to combine this shielding effectiveness with the required mechanical properties of structural materials. Samples of polyethylene-fiber reinforced epoxy matrix composite 1-5 cm thick were prepared at the NASA Marshall Space Flight Center and tested against a 500 MeV/nucleon Fe beam at the HIMAC facility of NIRS in Chiba, Japan. This paper presents measured and calculated results for the radiation transport properties of these samples.

Dust devils have been characterized as capable of lofting substantial masses of sift and dust to considerable heights (by Gillette & Sinclair, 1990, Metzger, and others). Their effective erosion of soil must derive from the convective thermodynamics that power the vortices. Unfortunately, the scarcity of detailed measurements of dust devils hampers both the ability to develop theories that articulate their behavior and to test the theories already proposed. The chase rig consists of a terrain-following 5-m vertical mast supporting 30 instruments that profile wind speed, temperature, pressure, and humidity. Additional single-level instruments measure particle impacts, particle charge states, and UV insolation levels (several of which were developed for the Beagle2 Mars lander). Dust devils could not sustain their thermal engine when ambient winds dropped below 2 m/s. Conversely, vortex structure was disbursed and destroyed when ambient winds exceeded 8 m/s, although in both cases short-lived vortices could develop. Under such conditions, a dozen events were well documented by datalogger and cameras. This report will present the latest findings from the 2004 field season as we strive to assimilate these simultaneous data sets.

Fifty school teams, teachers and educators from diverse communities across the United States, are selected annually in a peer competition. In this partnership with NASA, the NES teams will receive new teaching resources and technology tools to enhance learning in grades 4-9. Up to $17,500 is provided to purchase technology to support science and mathematics education. NASA hosts a yearly leadership conference and workshop for new schools during which NES educators and students previously selected share experiences. Surveys from each new NES inform NASA of the curricular and technological needs that the school will address during the partnership. Schools are informed of the principles and national standards that have been established by grade level for science, mathematics, technology, and geography. Geologists, concerned about earth science education in grades 4-9, should note that the standards in science address the structure of the Earth system, history of Earth and Earth in the solar system. Within the geography standards, environment and society are addressed, specifically human modification of the physical environment, the impact of physical systems on people and the use, distribution and importance of resources. Although the word geology does not appear in the standards, your awareness of the standards is important. You can volunteer to help teachers and parents in explorer schools through leading field trips, especially field trips through your university facilities. Your involvement is critical because teachers in grades 4-9 may have poor academic backgrounds in earth science. Your knowledge of the standards and willingness to provide content information will demonstrate that the subject of geology is involved in so many aspects of daily life.

A number of rocks at the Gusev site are perched, with a significant undercut above the surface; additional rocks show a feature of being eroded or etched at a height of one to three centimeters immediately above the soil line. Some rocks also show terracing, and others show a two-tone pattern of albedo, with a distinct dividing line between a lighter area near the surface and a darker color above the surface. In a small number of cases, the dividing line is correlated with a visible horizontal groove in the rock, most likely indicating an earlier location of burial of the rock. A number of explanations for this undercutting are possible. Perched rocks can be placed on the surface by deflation of the soil from underneath the rock. The surface etching may be abrasion due to reptation. Reptation, or surface creep, occurs as sand moves without leaving the surface, as small (100-200 micron particles) moved by saltation set larger particles in motion. These large particles are effective at abrading the rocks at the surface level. The structure of "ripple" features at the site is evidence to support reptation at the Gusev site. An alternate explanation is etching at the surface by chemically active grit.

In addition to its direct radiative effect, dust aerosol mediates ocean carbon uptake and the chemical cycles of other aerosols like sulfates. Dust observations during the past decade span measurements of local concentration and deposition to global satellite retrievals of aerosol optical thickness [Prospero et al., 2002]. Measurements of dust emission, whereby soil particles enter the atmosphere, are scarce. Because no single data set is sufficient to constrain the three-dimensional distribution of dust aerosol and its evolution with time, the dust cycle is currently estimated using models that are constrained by available measurements and retrievals.

The formation of such shocks is modeled using a piecewise parabolic method (PPM) code under a variety of conditions. The results of this modeling are used as a guide to study chondrule formation in a one-dimensional, finite shock wave. This model considers a mixture of chondrule-sized particles and micron-sized dust and models the kinetic vaporization of the solids. We found that only planetesimals with a radius of approximately 1000 km and moving at least approximately 8 km/s with respect to the nebular gas can generate shocks that would allow chondrule-sized particles to have peak temperatures and cooling rates that are generally consistent with what has been inferred for chondrules. Planetesimals with smaller radii tend to produce lower peak temperatures and cooling rates that are too high. However, the peak temperatures of chondrules are only matched for low values of chondrule wavelength-averaged emissivity. Very slow cooling (< approximately 100s of K/hr) can only be achieved if the nebular opacity is low, which may result after a significant amount of material has been accreted into objects that are chondrule-sized or larger, or if chondrules formed in regions of the nebula with small dust concentrations. Large shock waves of approximately the same scale as those formed by gravitational instabilities or tidal interactions between the nebula and a young Jupiter do not require this to match the inferred thermal histories of chondrules.

Ambiguous locations of the western termination of the 1999 Izmit, Turkey earthquake rupture and the location of the 1963 Yalova earthquake (M=6.4) add uncertainty to any single prediction of the earthquake-induced stress changes in the eastern Sea of Marmara in northwest Turkey. We use a historical earthquake catalog, mapped Marmara Sea fault traces, and fault slip distributions for the 1999 Izmit earthquake to determine the stress change scenarios that result from six plausible configurations for the western termination of 1999 Izmit earthquake rupture and the location of the 1963 Yalova earthquake. Coulomb stresses calculated using geomechanical models are increased on the Princes' Island, Cinarcik, and Armutlu fault segments in each case. In four of the six plausible rupture configurations, the Cinarcik Fault receives the greatest average stress change. In one other configuration, the average stress increase on the Princes' Islands fault is greatest. In another, the stress changes on the Cinarcik and Princes' Islands fault are comparable. Rupture initiating on either the Princes' Islands or Armutlu Faults would be favored to propagate onto the Central Marmara, or Imrali Fault, respectively, based on their favorable geometries of the respective fault intersections. Whereas rupture initiating on the Cinarcik Fault would be limited to a much shorter rupture based on its mapped western termination. Therefore, while the earthquake-induced stress changes may, in most cases, be greatest on the Cinarcik Fault, an earthquake initiating on this fault may produce a shorter cumulative rupture compared to rupture initiation on the two other major eastern Marmara Sea fault segments.

In particular, we focus on the forced aspects of this variability. The principle forcings are orbital, solar, volcanic and events (such as the 8.2 kyr BP event). Land use and greenhouse gases also play a small role. We discuss suitable comparisons to paleo-data and the appropriateness of model experimental design for single and multiple forcing runs using time-slices and transient simulations. As an example, we focus on the response to solar and volcanic forcing in the context of the Maunder Minimum, a cool period of the late 17th century and demonstrate that although (northern) hemispheric mean temperature changes can be reasonably simulated in most models, the details of regional patterns depend more heavily on the included physics. In particular, we highlight the role of the stratosphere as well as the importance of ocean and vegetation feedbacks.

The plains of Gusev Crater are dominated by olivine-bearing basalt (approximately Fo(60)) and Fe(3+)/Fe(total)=0.1-0.5. The oxide mineral generally present is magnetite. In contrast, initial results for the Columbia Hills are consistent with the presence of hematite and a ferrous iron phase, possibly pyroxene. Gusev spectra also have a ferric doublet (not jarosite) that is tentatively associated with nano-phase ferric oxide. A wider diversity of material is present at Meridiani Planum. Significantly, jarosite-bearing outcrop is present throughout the region, with good exposures in impact craters such as Eagle and Endurance (Fe(3+)/Fe(total) approximately 0.9). The Moessbauer identification of jarosite (a hydroxyl-bearing sulfate mineral) is evidence for aqueous, acid-sulfate processes on Mars. Hematite is observed within the outcrop matrix and in the spheroidal particles (Blueberries) found within the outcrop and as a surface lag. An isolated rock (Bounce Rock) was the only sample at either landing site whose iron-bearing phase was dominated by pyroxene. The basaltic sand in the central portion of Eagle Crater, in the intercrater plains, and between slabs of outcrop at both Eagle and Endurance Craters is olivine-bearing basalt. The widespread occurrence of olivine-bearing basalt at both MER landing sites implies that physical, rather than chemical, weathering processes dominate at the surface of contemporary Mars.

Well-sampled sections in Nevada (Egan Range) and Australia (DDH Mt Whelan 1) record both the +5 permil excursion in delta (super 13) C and higher frequency modulations that have an amplitude of 1 permil and a wavelength of about 20 meters. As the duration of the SPICE event is constrained by interpolation among available U-Pb ages, the higher frequency modulations can be plausibly associated with the 400 ka cycle in the eccentricity of the Earth's orbit. Long (600 Ma) numerical integrations of solar system dynamics, together with theoretical considerations, make it clear that the 400 ka cyclicity is metronomic, not chaotic. Therefore, the 400 ka signal in the Cambrian carbon isotope records may be used to: (1) provide an accurate duration for the Spice excursion and for biological and geological events within it; (2) demonstrate the existence of long-term climatic variability during the Cambrian that was recorded by the oceanic carbon cycle; and (3) assist with understanding how trivial changes in Earth's eccentricity can be responsible for amplified responses in the behavior of Earth's climate and its biogeochemical proxies.

Shock pressures associated with these impacts demagnetized parts of the crust, to an extent determined by shock resistance of magnetic materials in the crust. Impacts that form large basins generate pressures in excess of 1 GPa within a few crater radii of their impact sites. Crustal materials near the surface experience significantly reduced impact pressure, which varies with depth and distance from the impact point. We present new demagnetization experiments on magnetite (Fe (sub 3) O (sub 4) ), hematite (alpha -Fe (sub 2) O (sub 3) ), and titanohematite (Fe (sub 2-x) Ti (sub x) O (sub 3) where x<0.2). Our measurements show that pressures of approximately 1 GPa are sufficient to partially demagnetize all of these minerals. The efficiency of demagnetization by impact pressure is proportional to the logarithm of the minerals' magnetic coercivity. The impact pressure magnetic response from exsolved titanohematite samples is consistent with the magnetization decay near Prometheus impact basin and may point to an oxidized igneous rock in Terra Sirenum region at the time of acquisition of magnetic remanence. The remaining magnetic anomalies near large impact basins suggest moderate crustal coercivity. These anomalies point to titanomagnetite as a magnetic carrier and more reduced condition during crustal formation.

Yucatan, Mexico; and 2) Two volcanic fields in Arizona, USA. These data are used as terrestrial analogs to gauge whether carbonates found within Martian meteorites could have formed under similar conditions on the planet Mars. Yucatan carbonate delta (super 18) O (sub (SMOW)) values range from +23.78 to +31.07ppm, while delta (super 13) C (sub (PDB)) values range from -13.64 to +1.68ppm. The most (super 18) O and (super 13) C enriched carbonates consist of mud formed near the edge of a saltpan; the result of intense evaporation of HCO (sub 3) (super -) -rich fluids. (super 18) O and (super 13) C isotope composition of tsekel zone caliches, consisting of single hand specimens and layered samples, are more depleted. The layered samples contain caliche "crusts" which form layers within vugs and fractures in the host rock. In all cases the caliche crusts are isotopically lighter than their hosts. (super 13) C depletion within the crusts implies alteration in the vadose zone. In the Yucatan, light soil-gas CO (sub 2) , derived from oxidation of organic matter, dissolves in vadose water and mixes with heavier marine limestone-derived carbon. The result is HCO (sub 3) (super -) fluid with an intermediate delta (super 13) C composition. Eventually the HCO (sub 3) (super -) precipitates as layers of caliche or microcrystalline calcite in vugs and veins on or within the host limestone and is delta (super 13) C-depleted. Arizona samples consist of caliche collected from two volcanic fields. delta (super 18) O (sub (SMOW)) values range from +22.88 to +33.56ppm, while delta (super 13) C (sub (PDB)) values range from -5.02 to +11.21ppm. Pedogenic caliches, presumed to have been in contact with isotopically light soil gas, are delta (super 13) C-depleted, similar to the Yucatan caliches. Carbonates with heavier (super 18) O and (super 13) C values show the effects of forming from (super 18) O-rich evapo-concentrated HCO (sub 3) (super -) water. These data suggest (super 13) C enrichment due either to removal of (super 12) C by photosynthesizers in the evaporating drops or from evaporation effects and/or during freezing. If indeed Mars once had a hydrologic cycle where HCO (sub 3) (super -) fluids were subjected to evaporation and/or freezing, precipitated carbonate minerals would in turn be (super 18) O-and (super 13) C-enriched. Subsequent alteration could produce Martian carbonates whose delta (super 13) C and delta (super 18) O composition is highly fractionated with respect to the evaporation-produced carbonates.

During boreal spring, the trend is upward over southeastern China and downward over central eastern China. This study explores the forcing mechanism of these trends in association with the global sea-surface temperature (SST) variations on the interannual and interdecadal time scales. Results based on singular value decomposition (SVD) analyses show that the interannual variability of China precipitation in boreal spring and summer can be well defined by two centres of action for each season, which are covarying with two interannual modes of SSTs. The first SVD modes of precipitation in spring and summer, which are centred in southeastern China and northern China respectively, are linked to an el Nino-southern oscillation (ENSO)-like mode of SSTs. The second SVD modes of precipitation in both seasons are confined to central eastern China, and are primarily linked to SST variations over the warm pool and the Indian Ocean. Features of the anomalous 850 hPa winds and 700 hPa geopotential height corresponding to these modes support a physical mechanism that explains the causal links between the modal variations of precipitation and SSTs. On the decadal and longer time scale, similar causal links are found between the same modes of precipitation and SSTs, except for the case of springtime precipitation over central eastern China. For this case, while the interannual mode of precipitation is positively correlated with the interannual variations of SSTs over the warm pool and Indian Ocean, the interdecadal mode is negatively correlated with a different SST mode, i.e. the North Pacific mode. The latter is responsible for the observed downward trend of springtime precipitation over central eastern China. For all other cases, both the interannual and interdecadal variations of precipitation can be explained by the same mode of SSTs. The upward trend of springtime precipitation over southeastern China and downward trend of summertime precipitation over northern China are attributable to the warming trend of the ENSO-like mode. The recent frequent summertime floods over central eastern China are linked to the warming trend of SSTs over the warm pool and Indian Ocean.

This ecotone, the world's largest, stretches for over 13, 400 km and marks the transition between the northern limits of forests and the southern margin of the tundra. Because of the inaccessibility and large extent of this zone, remote sensing data can play an important role for mapping the characteristics and monitoring the dynamics. Basic understanding of the capabilities of existing space borne instruments for these purposes is required. In this study we examined the use of several remote sensing techniques for characterizing the existing tundra-taiga ecotone. These include Landsat-7, MISR, MODIS and RADARSAT data. Historical cover maps, recent forest stand measurements and high-resolution IKONOS images were used for local ground truth. It was found that a tundra-taiga transitional area can be characterized using multi-spectral Landsat ETM+ summer images, multi-angle MISR red band reflectance images, RADARSAT images with larger incidence angle, or multi-temporal and multi-spectral MODIS data. Because of different resolutions and spectral regions covered, the transition zone maps derived from different data types were not identical, but the general patterns were consistent.

Results indicate that the model generally reproduces observed distributions of Rn but there are some biases in the model related to differences in large-scale and convective transport. Simulations presented here use an off-line three- dimensional chemical transport model driven by assimilated winds and two scenarios of Rn fluxes (atom cm super(-1) s super(-1)) from ice-free land surfaces.

One such method is the surface reference technique (SRT), by which attenuation is estimated as the difference between the surface cross section outside the rain and the apparent surface cross section measured in rain. This and the Hitschfeld-Bordan method are used operationally to estimate rain rate using data from the precipitation radar (PR) aboard the Tropical Rainfall Measuring Mission (TRMM) satellite. To overcome some of the problems associated with the latest operational version of the SRT, a hybrid surface reference is defined that uses information from the along-track and cross-track variations of the surface cross sections in rain-free areas. Over ocean, this approach eliminates most of the discontinuities in the path-attenuation field. Self-consistency of the estimates is tested by processing the orbits backward as well as forward. Calculations from 2 weeks of PR data show that 90% of the rain events over ocean for which the SRT is classified as reliable or marginally reliable are such that the absolute difference between the forward and backward estimates is less than 1 dB.

The size is calculated from the area contained by total column ozone values less than 220 Dobson Units (DU) during September-October. The 220-DU value is used because it is lower than pre-1980 observed ozone values, and because it is in the strong ozone gradient region. We quantitatively show that the ozone hole size is primarily sensitive to effective stratospheric chlorine trends, and secondarily to the year-to-year variations in temperatures near the edge of the polar vortex. Temperatures are in turn sensitive to variations in tropospheric planetary wave forcing of the Southern Hemisphere stratosphere. Currently the average hole size reaches approximately 25 million km super(2) each spring. Slow decreases of ozone depleting substances will only result in a decrease of about 1 million km super(2) by 2015. This slow size decrease will be obscured by large dynamically forced year-to-year variations of 4 million km super(2) (1 capital sigma ), and possibly delayed by greenhouse gas cooling of the Antarctic stratosphere.

In this article, a Bayesian technique to evaluate uncertainties of the NN parameters (i.e., synaptic weights) is first presented. In contrast to more traditional approaches based on point estimation of the NN weights, we assess uncertainties on such estimates to monitor the robustness of the NN model. These theoretical developments are illustrated by applying them to the problem of retrieving surface skin temperature, microwave surface emissivities, and integrated water vapor content from a combined analysis of satellite microwave and infrared observations over land. The weight uncertainty estimates are then used to compute analytically the uncertainties in the network outputs (i.e., error bars and correlation structure of these errors). Such quantities are very important for evaluating any application of an NN model. The uncertainties on the NN Jacobians are then considered in the third part of this article. Used for regression fitting, NN models can be used effectively to represent highly nonlinear, multivariate functions. In this situation, most emphasis is put on estimating the output errors, but almost no attention has been given to errors associated with the internal structure of the regression model. The complex structure of dependency inside the NN is the essence of the model, and assessing its quality, coherency, and physical character makes all the difference between a blackbox model with small output errors and a reliable, robust, and physically coherent model. Such dependency structures are described to the first order by the NN Jacobians: they indicate the sensitivity of one output with respect to the inputs of the model for given input data. We use a Monte Carlo integration procedure to estimate the robustness of the NN Jacobians. A regularization strategy based on principal component analysis is proposed to suppress the multicollinearities in order to make these Jacobians robust and physically meaningful.

These models are developed empirically as functions of the surface and cloud properties provided by coincident high-resolution imager measurements over CERES field-of-view. However, approximately 5.6% of the CERES/Terra footprints lack sufficient imager information for a reliable scene identification. To avoid any systematic biases in regional mean radiative fluxes, it is important to provide TOA fluxes for these footprints. For this purpose, we apply a feedforward error-backpropagation Artificial Neural Network (ANN) technique to reproduce CERES/Terra ADMs relying only on CERES measurements. All-sky ANN- based angular distribution models are developed for 10 surface types separately for shortwave, longwave and window TOA flux retrievals. To optimize the ANN performance, we use a partially connected first hidden neuron layer and compact training sets with reduced data noise. We demonstrate the performance of the ANN-based ADMs by comparing TOA fluxes inferred from ANN and CERES anisotropic factors. The global annual average bias in ANN-derived fluxes relative to CERES is less than 0.5% for all ANN scene types. The maximum bias occurs over sea ice and permanent snow surfaces. For all surface types, instantaneous ANN-derived TOA fluxes are self-consistent in viewing zenith angle to within 9% for shortwave, 3.5% and 3% longwave daytime and nighttime, respectively.

The geographic distribution of wetlands is also climate-dependent. Doubled CO sub(2) simulations using this model show an increase in annual average wetland methane emissions from 156 to 277 Tg/yr, a rise of 78%. The bulk of this increase is due to enhanced emissions from existing tropical wetlands. Additionally, high northern latitude wetland areas expand and emissions nearly triple during Northern summer. The global increase represents [carat]620% of present-day inventories. These large values indicate that the potential response of natural emissions to climate change merit greater study, and should be included in projections of future global warming and tropospheric pollution.

AN - 85376396; pmid-15751468 AB - We examined the apparent dissociation of perceived length and perceived position with respect to the Müller-Lyer (M-L) illusion. With the traditional (two-chevron) figure, participants made accurate open-loop pointing responses at the endpoints of the shaft, despite the presence of a strong length illusion. This apparently non-Euclidean outcome replicated that of Mack, Heuer, Villardi, and Chambers (1985) and Gillam and Chambers (1985) and contradicts any theory of the M-L illusion in which mislocalization of shaft endpoints plays a role. However, when one of the chevrons was removed, a constant pointing error occurred in the predicted direction, as well as a strong length illusion. Thus, with one-chevron stimuli, perceived length and location were no longer completely dissociated. We speculated that the presence of two opposing chevrons suppresses the mislocalizing effects of a single chevron, especially for figures with relatively short shafts.

By selecting a variety of chemical functionalities in the polymers used to make sensors, it is possible to construct an array capable of identifying and quantifying a broad range of target compounds, such as alcohols and aromatics, and distinguishing isomers and enantiomers (mirror-image isomers). A model of the interaction between target molecules and the polymer-carbon black composite sensors is under development to aid in selecting the array members and to enable identification of compounds with responses not stored in the analysis library.

The objective of the mission is to provide exploratory global measurements of the earth's soil moisture at 10-km resolution with two- to three-days revisit and land-surface freeze/thaw conditions at 3-km resolution with one- to two-days revisit. The mission builds on the heritage of ground-based and airborne passive and active low-frequency microwave measurements that have demonstrated and validated the effectiveness of the measurements and associated algorithms for estimating the amount and phase (frozen or thawed) of surface soil moisture. The mission data will enable advances in weather and climate prediction and in mapping processes that link the water, energy, and carbon cycles. The Hydros instrument is a combined radar and radiometer system operating at 1.26 GHz (with VV, HH, and HV polarizations) and 1.41 GHz (with H, V, and U polarizations), respectively. The radar and the radiometer share the aperture of a 6-m antenna with a look-angle of 39 degrees with respect to nadir. The lightweight deployable mesh antenna is rotated at 14.6 rpm to provide a constant look-angle scan across a swath width of 1000 km. The wide swath provides global coverage that meet the revisit requirements. The radiometer measurements allow retrieval of soil moisture in diverse (nonforested) landscapes with a resolution of 40 km. The radar measurements allow the retrieval of soil moisture at relatively high resolution (3 km). The mission includes combined radar/radiometer data products that will use the synergy of the two sensors to deliver enhanced-quality 10-km resolution soil moisture estimates. In this paper, the science requirements and their traceability to the instrument design are outlined. A review of the underlying measurement physics and key instrument performance parameters are also presented.

A detailed understanding of the relative importance of vegetation phenology and meteorology, two of the main forcings of ecosystem forecasts, and the likely impact of errors in phenological and (or) meteorological forecasts are required prior to management implementation. Using the terrestrial observation and prediction system (TOPS) and 1982-1997 leaf area index (LAI) and meteorology for the conterminous United States, we tested the relative importance of interannual variability in meteorology and LAI for soil water simulations. In nearly all cases, meteorological variability influenced simulations far more than did LAI; the effects of ignoring realistic variability in either variable were most pronounced in arid, low-LAI regions. We then identified the critical meteorological forecast errors in temperature and precipitation that were required to generate statistically significant differences in 1-week soil water forecasts. Temperature critical errors approached 10 degrees C in winter but were only about 2-3 degrees C in summer. Precipitation critical errors were much more constant throughout the year and were usually less than 1 cm (error in weekly total precipitation).

Satellite-based soil moisture can be obtained from passive microwave, active microwave, and optical sensors, although the coarse spatial resolution of passive microwave and the inability to obtain vertically resolved information from optical sensors limit their usefulness for watershed-scale applications. Active microwave sensors such as synthetic aperture radar (SAR) currently represent the best approach for obtaining spatially distributed surface soil moisture at scales of 10-100 m for watersheds ranging from 1 000 to 25 000 km (super 2) . Although SAR provides surface soil moisture, the applications listed above require vertically resolved soil moisture profiles. To obtain distributed soil moisture profiles, a combined approach of calibration and data assimilation in soil vegetation atmosphere transfer (SVAT) models based on recent advances in soil physics is the most promising avenue of research. This review summarizes the state of the science using current satellite-based sensors to determine watershed-scale surface soil moisture distribution and the state of combining SVAT models with data assimilation and calibration approaches for the estimation of profile soil moisture. The basic conclusion of this review is that currently orbiting SAR sensors combined with available SVAT models could provide distributed profile soil moisture information with known accuracy at the watershed scale. The priority areas for future research should include image-based approaches for mapping surface roughness, determination of soil moisture in densely vegetated sites, active and passive microwave data fusion, and joint calibration and data assimilation approaches for a combined remote sensing-modeling system. For validation, a worldwide in situ soil moisture monitoring program should be implemented. Finally, to realize the full potential of satellite-based soil moisture estimation for watershed applications, it will be necessary to continue sensor development, improve image availability and timely delivery, and reduce image cost.

It is suggested that during the mean high-obliquity regime ( approximately 5 to 10 Ma ago), a few obliquity cycles may have been sufficient to empty the polar reservoirs and form massive glaciers approximately 3 km thick on Tharsis Montes and on Olympus Mons. It is possible that the mean near-surface ice detected by Mars Odyssey is only the upper layer of a much deeper ice reservoir in high latitudes of both hemispheres, and where layered sedimentary deposits rich in water-ice and periglacial features also occur and support this interpretation.

DMIP simulations from twelve different models are compared with both observed streamflow and lumped model simulations. The lumped model simulations were produced using the same techniques used at National Weather Service River Forecast Centers (NWS-RFCs) for historical calibrations and serve as a useful benchmark for comparison. The differences between uncalibrated and calibrated model performance are also assessed. Overall statistics are used to compare simulated and observed flows during all time steps, flood event statistics are calculated for selected storm events, and improvement statistics are used to measure the gains from distributed models relative to the lumped models and calibrated models relative to uncalibrated models. Although calibration strategies for distributed models are not as well defined as strategies for lumped models, the DMIP results show that some calibration efforts applied to distributed models significantly improve simulation results. Although for the majority of basin-distributed model combinations, the lumped model showed better overall performance than distributed models, some distributed models showed comparable results to lumped models in many basins and clear improvements in one or more basins. Noteworthy improvements in predicting flood peaks were demonstrated in a basin distinguishable from other basins studied in its shape, orientation, and soil characteristics. Greater uncertainties inherent to modeling small basins in general and distinguishable inter-model performance on the smallest basin (65 km (super 2) ) in the study point to the need for more studies with nested basins of various sizes. This will improve our understanding of the applicability and reliability of distributed models at various scales.

The efficiency epsilon (T (sub r) ) of a remanent magnetization (REM) is the ratio of the natural remanent magnetization M (sub nr) (T (sub r) ) to the saturation remanence J (sub sr) (T (sub r) ). We report a power law relationship with exponent related to J (sub s) (T (sub r) ) and unit slope indicating a linear relationship. Thus logepsilon (T (sub r) ) of M (sub tr) (T (sub r) ) in equidimensional-shaped magnetic minerals of contrasting saturation magnetization J (sub s) (T (sub r) ) plots linearly with the logarithm of the applied magnetic field B along separate grain-size-independent straight lines with nearly unit slope and offsets related to J (sub s) (T (sub r) ). This empirical relationship is well suited for paleofield-intensity estimation, predicts strong magnetization of hematite and pyrrhotite in weak fields, and can be used as an assessment tool for observed remanence in planetary and meteoritic objects.

The homogenization temperatures of fluid inclusions within the samples were quantified before and after the experimental shock events; they show a systematic and gradual evolution with increasing shock pressure. Some fluid inclusions survive shock pressures of 6 GPa, yet they exhibit an increase in homogenization temperature, suggesting that re-equilibration occurred because of internal overpressures. Decrepitated fluid inclusions were observed in the 6 and 7.6 GPa samples, whereas textures indicative of the collapse of fluid inclusions due to internal underpressure were observed in samples shocked at 7.6-12 GPa. No features that could be directly related to fluid inclusions were observed in samples shocked at pressures > 12 GPa. It is considered that if the fluid inclusions survive the original decrease in volume during shock compression, the initial decrease in volume is overprinted by the subsequent effects of elevated temperature at ambient pressure, leading to an increase in inclusion volume and homogenization temperature. Therefore, homogenization temperatures of fluid inclusions in shocked materials should be considered a maximum value. The rarity of fluid inclusions in meteorites may be a result of shock processing, and may not reflect a fluid-poor environment on the parent body.

Answers to key questions concerning the comparative origin and evolution of Mars and Earth will not be forthcoming without a rigid Martian chronology, enabling the construction of a time scale comparable to Earth's. Priorities for exploration include calibration of the cratering rate, dating major volcanic and fluvial events and establishing chronology of the polar layered deposits. If extinct and/or extant life is discovered, the chronology of the biosphere will be of paramount importance. Many radiometric and cosmogenic techniques applicable on Earth and the Moon will apply to Mars after certain baselines (e.g. composition of the atmosphere, trace species, chemical and physical characteristics of Martian dust) are established. The high radiation regime may pose a problem for dosimetry-based techniques (e.g. luminescence). The unique isotopic composition of nitrogen in the Martian atmosphere may permit a Mars-specific chronometer for tracing the time-evolution of the atmosphere and of lithic phases with trapped atmospheric gases. Other Mars-specific chronometers include measurement of gas fluxes and accumulation of platinum group elements (PGE) in the regolith. Putting collected samples into geologic context is deemed essential, as is using multiple techniques on multiple samples. If in situ measurements are restricted to a single technique it must be shown to give consistent results on multiple samples, but in all cases, using two or more techniques (e.g. on the same lander) will reduce error. While there is no question that returned samples will yield the best ages, in situ techniques have the potential to be flown on multiple missions providing a larger data set and broader context in which to place the more accurate dates.

Difference maps, MPFSST - ASST2, along with the application of a simple statistical regression model to aerosol and cloud data from the Total Ozone Mapping Spectrometer (TOMS), are used to examine the impact of possible aerosol and cloud contamination. Differences varied regionally, but the largest biases were seen off western Africa. Nighttime and daytime differences off western Africa were reduced from -0.5 degree to -0.2 degree C and from -0.1 degree to 0 degree C, respectively. Significant cloud flagging, based on the model, occurred in the Indian Ocean, the equatorial Pacific, and in the vicinity of the Gulf Stream. Comparisons of the MPFSST and the ASST2 with in situ data from the 2002 version of the World Oceanic Database (WOD02) off western Africa show larger mean differences for the MPFSST. The smallest mean differences occurred for nighttime ASST2 - WOD02 with a value of 0.0 degree plus or minus 0.4 degree C.

To demonstrate this technique, several types of natural samples, including beach sand, seawater, deep-sea sediment, and two soil samples from the Atacama Desert, were heated to a temperature of 500 degree C for several seconds under reduced pressure. The sublimate was collected on a cold finger, and the amount of adenine released from the samples was then determined by high-performance liquid chromatography with UV absorbance detection. Based on the total amount of adenine recovered from DNA and RNA in these samples, we estimated bacterial cell counts ranging from -10 super(5) to 10 super(9) E. coli cell equivalents per gram. For most of these samples, the sublimation-based cell counts were in agreement with total bacterial counts obtained by traditional DAPI (4,6-diamidino-2- phenylindole) staining.

Observed large-scale advective tendencies for potential temperature, water vapor mixing ratio, and horizontal momentum derived from field campaigns are used as the main forcing. The atmospheric temperature and water vapor budgets from the model results show that the two largest terms are net condensation (heating/drying) and imposed large-scale forcing (cooling/moistening) for tropical oceanic cases though not for midlatitude continental cases. These two terms are opposite in sign, however, and are not the dominant terms in the moist static energy budget. The balance between net radiation, surface latent heat flux, and net condensational heating vary in these tropical cases, however. For cloud systems that developed over the South China Sea and eastern Atlantic, net radiation (cooling) is not negligible in the temperature budget; it is as large as 20% of the net condensation. However, shortwave heating and longwave cooling are in balance with each other for cloud systems over the west Pacific region such that the net radiation is very small. This is due to the thick anvil clouds simulated in the cloud systems over the Pacific region. The large-scale advection of moist static energy is negative, as a result of a larger absolute value of large-scale advection of sensible heat (cooling) compared to large-scale latent heat (moistening) advection in the Pacific and Atlantic cases. For three cloud systems that developed over a midlatitude continent, the net radiation and sensible and latent heat fluxes play a much more important role. This means that the accurate measurement of surface fluxes and radiation is crucial for simulating these midlatitude cases. The results showed that large-scale mean (multiday) precipitation efficiency (PE) varies from 24% to 31% (or 32% to 45% using a different definition of PE) between cloud systems from different geographic locations. The model results showed that there is no clear relationship between the PE and rainfall, the positive cloud condensation (condensation plus deposition), or the large-scale forcing. But, the model results suggest that cases with large, positive net condensation terms in the moist static energy budget tend to have a large PE. The PE and its relationship with relative humidity and the vertical shear of the horizontal wind are also examined using 6-hourly model data. The model results suggest that there is no clear relationship between the individual PE and total mass-weighted relative humidity or the middle- and upper-tropospheric moisture for each case. The model results suggest that for the west Pacific and east Atlantic cases, PE slightly decreases with increasing middle-tropospheric wind shear in low to moderate shear regimes. The correlation (based on the best polynomial fit) is quite weak however. No strong relationship between PE and wind shear was found for the South China Sea and cases over the United States.

The latter was obtained by substituting the GCM-simulated precipitation, which is used to drive the GCM's land surface component, with observed pentad-mean precipitation at each time step of the model's integration. With this substitution, the simulated soil moisture correlates well with an independent estimate of observed soil moisture in all seasons over the entire U.S. continent. Significant enhancements for the predictability of surface-air temperature and precipitation were found in boreal late spring and summer over the U.S. continent. Anomalous pattern correlations of precipitation and surface-air temperature over the U.S. continent in the June-August season averaged for the 1979-2000 period increased from 0.01 and 0.06 for the GCM simulations without precipitation substitution to 0.23 and 0.31, respectively, for the simulations with precipitation substitution. The results provide an estimate for the limits of potential predictability if soil-moisture variability is to be perfectly predicted. However, this estimate may be model dependent and needs to be substantiated by other modeling groups.

One estimation technique is a terrestrial water budget, i.e., total precipitation minus the sum of evapotranspiration and net runoff equals the change in water storage. Gravity Recovery and Climate Experiment (GRACE) satellite gravity observations are now enabling closure of this equation by providing the terrestrial water storage change. Equations are presented here for estimating evapotranspiration using observation based information, taking into account the unique nature of GRACE observations. GRACE water storage changes are first substantiated by comparing with results from a land surface model and a combined atmospheric-terrestrial water budget approach. Evapotranspiration is then estimated for 14 time periods over the Mississippi River basin and compared with output from three modeling systems. The GRACE estimates generally lay in the middle of the models and may provide skill in evaluating modeled evapotranspiration.

The observations included a comprehensive set of photochemical parameters, e.g. NO, O sub(3), and CO. It is worthy to note that not only were OH and HO sub(2) observed, but also HO sub(x) precursor species CH sub(2)O, H sub(2)O sub(2), and HONO were measured. Previous studies have suggested that HONO is the major source of OH/HO sub(x) in the Arctic; however, observed HONO levels at SP induced dramatic model overprediction of both HO sub(x) and NO sub(x) when used to constrain the model calculations. In contrast, model predictions constrained by observed values of CH sub(2)O and H sub(2)O sub(2) are consistent with the observations of OH and HO sub(2) (i.e. within 20%) for more than half of the data. Significant model overpredictions of OH, however, were seen at the NO levels lower than 50 pptv or higher than 150 pptv. An analysis of HO sub(x) budget at the median NO level suggests that snow emissions of H sub(2)O sub(2) and CH sub(2)O are the single most important primary source of SP HO sub(x), contributing 46% to the total source. Major sinks for HO sub(x) are found to be dry deposition of HO sub(2)NO sub(2) and HNO sub(3) as well as their reactions with OH. Although ISCAT 2000 led to a major progress in our understanding of SP HO sub(x) chemistry, critical aspects of this chemistry are still in need of further investigation.

Combustion of elemental sulfur in the fire produced dense clouds of sulfur dioxide (SO sub(2)) that were detected from space by the Earth Probe Total Ozone Mapping Spectrometer (EP TOMS) on 18 days. Estimated daily SO sub(2) production from the continuously emitting source closely mirrors contemporaneous thermal infrared radiance from the fire sensed in the 3.96 mu m band of the Moderate Resolution Imaging Spectroradiometer (MODIS). We calculate total SO sub(2) production during the blaze amounting to similar to 600 kilotons, which is roughly commensurate with the predicted SO sub(2) yield from the inventory of elemental sulfur allegedly destroyed by the fire when potential SO sub(2) losses are considered. This event is the largest non-volcanic SO sub(2) emission incident measured to date by any TOMS instrument.

AN - 85374424; pmid-15478423 AB - In order to determine the effect of the number of sonic boom occurrences on annoyance, a computer-based system was developed for studying the subjective response of people to the occurrence of simulated sonic booms in their homes. The system provided a degree of control over the noise exposure not found in community surveys and a degree of situational realism not available in the laboratory. A system was deployed for eight weeks in each of 33 homes. Each day from 4 to 63 sonic booms were played as the test subject went about his or her normal activities. At the end of the day, the test subjects rated their annoyance to the sonic booms heard during the day. The sonic booms consisted of different combinations of waveforms, levels, and occurrence rates. The experiment confirmed that the increase in annoyance resulting from multiple occurrences can be modeled by the addition of the term "10 * log(number of occurrences)" to the sonic boom level. Of several noise metrics considered, perceived level was the best annoyance predictor. Comparisons of the subjective responses to the different sonic boom waveforms found no differences that were not accounted for by the noise metrics.

In these calculations, we start with likely compositions of the original parent body and asteroidal fluids that are far from thermodynamic equilibrium, and metastable and stable equilibrium constraints are imposed as the total Gibbs free energy of the parent body environment is minimized. The results of these calculations suggest that the classes of soluble organic compounds present in carbonaceous chondrite meteorites could have formed during relatively low temperature aqueous alteration of the meteorite parent body or bodies. The main controls on the potential for synthesis and transformation of organic compounds were the oxidation state of the rock/fluid system, the bulk composition of that system, and the temperatures that were achieved during the alteration event or events. It also appears that the alteration mineral assemblages were influenced by the presence of soluble organic compounds and reaction among them.

Two glaciers south of the collapse area show little change in speed or elevation. Seasonal variations in speed preceding the large post-collapse velocity increases suggest that both summer melt percolation and changes in the stress field due to shelf removal play a major role in glacier dynamics.

While quartz and asbestos have received considerable attention, pyrite (FeS (sub 2) ), the most abundant iron sulfide, has received almost no attention in this context. Batch experiments were performed to determine the effects of pyrite-induced OH on RNA in the presence and absence of lipids. The effect of the presence of lipids on RNA stability was evaluated by coating pyrite as well as encapsulating RNA in bilayer-vesicles. Rapid degradation of RNA was observed in the presence of pyrite, whereas significantly slower RNA decomposition was observed in experiments in the presence of lipids, regardless of whether the lipids were coating the pyrite or encapsulating the RNA. Given the presence of pyrite on early Earth, its reaction with water may have formed hydroxyl radicals (OH), which could have limited the stability of prebiotic biomolecules critical to the emergence and evolution of life. The lipid-mediated reduction of RNA decomposition suggests a possible protective mechanism that could have been a prerequisite for the origin of life.

Hektoria, Green and Evans glaciers accelerated eightfold between 2000 and 2003 and decelerated moderately in 2003. Jorum and Crane glaciers accelerated twofold in early 2003 and threefold by the end of 2003. In contrast, Flask and Leppard glaciers, further south, did not accelerate as they are still buttressed by an ice shelf. The magnitude of the glacier changes illustrates the importance of ice shelves on ice sheet mass balance and contribution to sea level change. (mod. journ. abstr.)

The overall petrography of Y980459 is similar to those of olivine-phyric shergottites, but the absence of plagioclase and Ca phosphates make Y980459 unique. Because of the absence of maskelynite, Y980459 is not a shergottite if we employ the classic definition of shergottite. Both olivine and pyroxenes are extensively zoned. The most magnesian olivine composition is Fo (sub 86) and the olivine compositions are related to three different occurrence types of olivine (large phenocrysts, groundmass, and mesostasis). Pyroxenes have orthopyroxene cores (En (sub 81) Fs (sub 17) Wo (sub 2) ) mantled by pigeonite with the rims of augite. The mineralogy of Y980459 suggests that rapid crystallization of the parent magma caused significant undercooling and plagioclase did not nucleate. Probably, rapid transport of the Y980459 parent magma from the depth to the Martian surface crystallized olivine and pyroxene at first and eruption onto the surface quenched the magma producing the glassy mesostasis. Because olivine and pyroxene compositions of Y980459 are the most magnesian among Martian meteorites, Y980459 would represent one of the most primitive Martian magmas and derive from a highly reduced mantle. It seems that Y980459 contains no cumulus component, suggesting that Y980459 is a melt. In this sense, Y980459 is similar to QUE94201. The similarity in mineralogy and chemistry between Y980459 and olivine-phyric shergottites suggests derivation from a similar highly reduced mantle. However, Y980459 was the only sample that directly erupted onto the Martian surface without any accumulation processes.

A custom user interface was developed for easy access and manipulation of the abundance data. The database contains almost 3000 individual analyses of more than 1000 individual meteorites. Most major and minor elements are included, as well as small number of trace elements measurable by remote-sensing gamma-ray spectroscopy (notably Th and U). All meteorite classes show variability in bulk compositions between individual analyses. Some of this spread is intrinsic to the parent bodies of the meteorites. However, some variability is undoubtedly due to systematic uncertainties, caused by inter-laboratory bias, misclassification, effect of weathering, and unrepresentative sampling. We use the database here to investigate both how well different meteorite groups can be distinguished on the basis of bulk compositions and how bulk compositions can be distinguished on the basis of bulk compositions and how bulk compositions can be related to the cosmochemical and geological processes that produced them. The major elements measurable by X-ray and gamma-ray remote-sensing-oxygen, magnesium, aluminum, silicon, sulfur, calcium and iron-reflect to differing degrees nebular elemental fractionations and parent-body igneous processes and can be used together to distinguish most classes sub-classes of meteorites. Potassium is potentially useful as a tracer of thermal processes in the early solar system. Thorium and uranium abundances could be used to trace igneous processes on differentiated asteroids.

The meteorites in this study have a range of petrographic types from LL3.3 to LL6, and shock stages from S1 to S4. These meteorites reveal a range of K-Ar ages from > or =3.66 to > or =4.50 Ga, and peak ages from > or =3.74 to > or =4.55 Ga. Significantly, three of the eight chondrites (LL4, 5, 6) have K-Ar ages of approximately 4.27 Ga. One of these (MIL99301) preserves an (super 39) Ar- (super 40) Ar age of 4.23+ or -0.03 Ga from low-temperature extractions, and an older age of 4.52+ or -0.08 Ga from the highest temperature extractions. In addition, an igneous-textured impact melt DOM85505,22 has a peak (super 39) Ar- (super 40) Ar age of > or =4.27 Ga.We interpret these results as evidence for impact events that occurred at about 4.27 Ga on the LL parent body that produced local impact melts, reset the (super 39) Ar- (super 40) Ar ages of some meteorites, and exhumed (or interred) others, resulting in a range of cooling ages. The somewhat younger peak age of 3.74 Ga from GRO95658 (LL3.3) suggests an additional impact event close to timing of impact-reset ages of some other ordinary chondrites between 3.6-3.8 Ga. The results from MIL99301 suggest that some apparently unshocked (S1) chondrites may have substantially reset (super 39) Ar- (super 40) Ar ages. A previous petrographic investigation of MIL99301 suggested that reheating to temperatures less than or equal to type 4 petrographic conditions (600 degrees C) caused fractures in olivine to anneal, resulting in a low apparent shock stage of S1 (unshocked). The (super 39) Ar- (super 40) Ar age spectrum of MIL99301 is consistent with this interpretation. Older ages from high-T extractions may date an earlier impact event at 4.52+ or -0.08 Ga, whereas younger ages from lower-T extractions date a later impact event at 4.23+ or -0.03 Ga that may have caused annealing of feldspar and olivine.

This cooling is consistent with circulation changes associated with a shift in the Southern Annular Mode (SAM). It has been suggested that both Antarctic ozone depletion and increasing greenhouses gases have contributed to these trends. We show that a climate model including the stratosphere and both composition changes reproduces the vertical structure and seasonality of observed trends. We find that the two factors have had comparable surface impacts over recent decades, though ozone dominates above the middle troposphere. Projected impacts of the two factors on circulation over the next fifty years oppose one another, resulting in minimal trends. In contrast, their effects on surface climate reinforce one another, causing a departure from the SAM pattern and a turnabout in Antarctic temperatures, which rise more rapidly than elsewhere in the Southern Hemisphere.

The 6-yr (1998-2003) high-quality Tropical Rainfall Measuring Mission (TRMM) rainfall, sea surface temperature (SST), water vapor, and cloud liquid water observations are applied along with the NCEP-NCAR reanalysis wind components and a 4-yr (2000-2003) Quick Scatterometer (Quik SCAT) satellite-observed surface wind product. Major mean rainfall over West Africa tends to be concentrated in two regions and is observed in two different seasons, manifesting an abrupt shift of the mean rainfall zone during June-July: (i) near the Gulf of Guinea (about 5 degree N), intense convection and rainfall are seen during April-June and roughly follow the seasonality of SST in the tropical eastern Atlantic, and (ii) along the latitudes of about 10 degree N over the interior of the West African continent, a second intense rain belt begins to develop in July and remains there during the later summer season. This belt coexists with a northward-moving African easterly jet (AEJ) and its accompanying horizontal and vertical shear zones, the appearance and intensification of an upper-tropospheric tropical easterly jet (TEJ), and a strong low-level westerly flow. Westward-propagating wave signals [i.e., African easterly waves (AEWs)] dominate the synoptic-scale variability during July-September, in contrast to the evident eastward-propagating wave signals during May-June. The abrupt shift of the mean rainfall zone thus turns out to be a combination of two different physical processes: (i) evident seasonal cycles in the tropical eastern Atlantic Ocean, which modulate convection and rainfall near the Gulf of Guinea by means of SST thermal forcing and SST-related meridional gradient; and (ii) the interaction among the AEJ, TEJ, low-level westerly flow, moist convection, and AEWs during July-September, which modulates rainfall variability in the interior of West Africa, primarily within the ITCZ rain band. Evident seasonality in synoptic-scale wave signals is shown to be a good indication of this seasonal evolution.

Information available from Earth and space science missions indicate that about 59% of the spacecraft and about 18% of the instrument groups experienced some effect from the solar activity. This paper summarizes the impacts on spacecraft, instruments, and science data. The database that the paper is based on describes spacecraft and instrument effects observed as well as mission operators' preventive actions from 34 reporting missions. The database is Appendix A and provides additional material that could be of interest and that could be useful to satellite developers, operators, instrument managers, and scientists. The types of environmental effects observed were electronic upsets, housekeeping and science noise, proton degradation to solar arrays, upper atmosphere-induced changes to orbit dynamics, high levels of accumulated radiation, and proton heating. The paper develops best practices that are intended to foster continued and expanded feedback on the space environment in all mission phases, to promote designing to the mission's observing mode so that planning is appropriate to mission science goals, to distribute operational experience and lessons learned widely among both developing and operating missions, and to uniformly apply the developed knowledge base among NASA's missions.

To counter the second limitation, a dozen climate-modeling groups have recently performed the same highly controlled numerical experiment as part of a coordinated comparison project. This allows a multimodel estimation of the regions on Earth where precipitation is affected by soil moisture anomalies during Northern Hemisphere summer. Potential benefits of this estimation may include improved seasonal rainfall forecasts.

AN - 67304333; 15856586 AB - A potential dosimeter based on aqueous frozen solutions and solid-state salt are presented for the evaluation of the energy transferred during the interaction of high-energy radiation with matter at low temperature. The foundation of these dosimeters, both the solid state and the frozen solutions, is based on the measurement of the change of the iron oxidation state. The systems were irradiated with gamma radiation at different doses (up to 10 MGy), and at different temperatures (from 77 to 298 K). The irradiated samples were analysed by UV-spectroscopy and Mössbauer spectroscopy. A theoretical model was developed for the chemical reactions system. This model reproduces the experimental effects produced by the irradiation in aqueous solutions of ferrous salt. The results showed that the response of the dosimeters depends on the irradiation temperature. At low-radiation doses, the response was linear. In particular, this work can be applied to low-temperature dosimetry can be specially applied to simulation experiments of extraterrestrial bodies, as well as in general to space research. c2004 Published by Elsevier Ltd.

AN - 67304304; 15856574 AB - The thermoluminescence (TL) and optically stimulated luminescence (OSL) response of Al2O3 dosimeters to high-energy heavy charged particles (HCP) has been studied using the heavy ion medical accelerator at Chiba, Japan. The samples were Al2O3 single-crystal chips, of the type usually known as TLD-500, and Luxel(TM) dosimeters (Al2O3:C powder in plastic) from Landauer Inc. The samples were exposed to 4He (150 MeV/u), 12C (400 MeV/u), 28Si (490 MeV/us) and 56Fe (500 MeV/u) ions, with linear energy transfer values covering the range from 2.26 to 189 keV/micrometers in water and doses from 1 to 100 mGy (to water). A 90Sr/90Y beta source, calibrated against a 60Co secondary standard, was used for calibration purposes. For OSL, we used both continuous-wave OSL measurements (CW-OSL, using green light stimulation at 525 nm) and pulsed OSL measurements (POSL, using 532 nm stimulation from a Nd:YAG Q-switched laser). The efficiencies (eta HCP, gamma) of the different HCPs at producing OSL or TL were observed to depend not only upon the linear energy transfer (LET) of the HCP, but also upon the sample type (single crystal chip or Luxel(TM)) and the luminescence method used to define the signal--i.e. TL, CW-OSL initial intensity, CW-OSL total area, or POSL. Observed changes in shape of the decay curve lead to potential methods for extracting LET information of unknown radiation fields. A discussion of the results is given, including the potential use of OSL from Al2O3 in the areas of space radiation dosimetry and radiation oncology. c2004 Elsevier Ltd. All rights reserved.

AN - 67294414; 15806749 AB - Discussions of future human expeditions into the solar system generally focus on whether the next explorers ought to go to the Moon or to Mars. The only mission scenario developed in any detail within NASA is an expedition to Mars with a 500-day stay at the surface. The technological capabilities and the operational experience base required for such a mission do not now exist nor has any self-consistent program plan been proposed to acquire them. In particular, the lack of an Abort-to-Earth capability implies that critical mission systems must perform reliably for 3 years or must be maintainable and repairable by the crew. As has been previously argued, a well-planned program of human exploration of the Moon would provide a context within which to develop the appropriate technologies because a lunar expedition incorporates many of the operational elements of a Mars expedition. Initial lunar expeditions can be carried out at scales consistent with the current experience base but can be expanded in any or all operational phases to produce an experience base necessary to successfully and safely conduct human exploration of Mars.

AN - 67292899; 15856580 AB - The properties of LiF:Mg,Ti (distributed as, e.g., TLD-100 or MTS-N), the most frequently used thermoluminescent detector, have been optimised for measurements of sparsely ionizing radiation (gamma rays), typically encountered in radiation protection or clinical dosimetry. However, these detectors need also to be applied in conditions of mixed-field dosimetry with a high-LET component, such as those encountered in heavy ion beams or in space. At the Institute of Nuclear Physics in Kraków a new type of LiF:Mg,Ti detector (named MTT) has been recently developed through modification of its dopant composition. This composition is intended to increase the detection efficiency after a dose of high-LET radiation. The concentration of dopants in the MTT material is: CMg=50 ppm, and CTi=120 ppm, i.e. about a three times less of magnesium and about 10 times more of titanium content, compared with the standard MTS-N. The MTT TL detectors feature an increased relative efficiency to high-LET radiation, which for 5 MeV alpha-particles is about twice that of standard LiF:Mg,Ti. The response of MTT detectors has been studied in charged particle beams of the HIMAC accelerator in Chiba, Japan and in Dubna, Russia. The main foreseen application of MTT detectors are dose measurements in space. The dose after high-LET exposure can be estimated from the difference of the response of MTS and MTT detectors. In the near future MTT detectors will be applied in the "Matroshka" experiment. Within this experiment a specially constructed human phantom will be exposed in free space (outside the International Space Station) for 1 year. The phantom will incorporate a few thousand measuring points enabling radiation doses to particular organs to be determined. c2003 Elsevier Ltd. All rights reserved.

AN - 67287109; 15856584 AB - The dosimetric properties of the newly developed KLT-300 (KAERI LiF:Mg,Cu,Na,Si TL detector) in KAERI (Korea Atomic Energy Research Institute) were investigated. The sensitivity of the TL detector was about 30 times higher than that of the TLD-100 by light integration. In the study of the dose linearity of the detector, the dose response was very linear up to 10 Gy and a sublinear response was observed at higher doses. The energy response of the detector was studied for photon energies from 20 to 662 keV. The results show that a maximum response of 1.004 at 53 keV and a minimum response of 0.825 at 20 keV were observed. The reproducibility study for the TL detector was also carried out. The coefficients of variation for each detector separately did not exceed 0.016, and for all the 10 detectors collectively it was 0.0054. IEC Standard requires that the coefficient of variation shall not exceed 0.075. So, the reproducibility of this new TL detector sufficiently satisfied the IEC requirements. A detection threshold of the detector was investigated and found to be 70 nGy by Harshaw 4500 TLD Reader. c2004 Elsevier Ltd. All rights reserved.

AN - 67287001; 15856581 AB - Radiation dosimetry is a very important issue in space research and in experiments that try to simulate chemical processes that may occur in cometary nucleus, interstellar grains, and other extraterrestrial environments, due to their irradiation by cosmic rays. The temperature effect is an important factor that has not been considered in many of these experiments. In this work, this effect was studied in TLD dosimeters exposed to gamma rays. The irradiations were done from 77 to 298 K in a gamma cell unit with a dose rate of 1.0 Gy/s. Results obtained for CaSO4:Dy show that there is a considerable effect in the evaluation of the dose as function of the irradiation temperature. c2003 Elsevier Ltd. All rights reserved.

AN - 67286931; 15856571 AB - Thermoluminescent detectors (TLDs) are widely used for the dosimetry of photons and electrons. They are less used for the radiation with higher linear energy transfer (LET). One of the reasons for that is that their TL relative efficiency eta decreases for the most of them with increasing LET. The paper presents first a review of author's experimental results in which eta was established for charged particles having LET of the order from 1 to 100 keV/micrometers in tissue. Among TLDs studied were known materials like LiF:Mn; Ti; Al-P glass; CaSO4:Dy; Al2O3:Na; and Al2O3:C. It was found that the dependence of their eta on LET is not the same for all TLDs studied. The response of the same materials to neutrons was also studied. It was found that both eta as the relative response (RR) defined in terms of absorbed dose in tissue are different, they depend critically also on the composition. When a TLD contains nuclei like 6Li and 10B, their RR would be rather high. As far as eta is concerned, the same tendencies were observed as for charged particles, i.e. when average LET of secondary particles formed in a TLD increases, their eta generally decreases. c2003 Elsevier Ltd.

For over 10 years, under various ESA contracts the flight experiment was defined, designed, breadboarded and set up. For the safety of the crew, ANITA can detect and quantify quasi on-line and simultaneously 32 trace gases with ppm or sub-ppm detection limits. The self-standing measurement system is based on Fourier Transform Infrared Spectrometer (FTIR) technology. The system represents a versatile air monitor allowing for the first time the detection and monitoring of trace gas dynamics of a spacecraft atmosphere. It is envisaged to accommodate ANITA in a Destiny (US LAB) Express Rack on the ISS. The transportation to the ISS is planned with the first ATV 'Jules Verne'.

ER - TY - JOUR T1 - High-calcium pyroxene as an indicator of igneous differentiation in asteroids and meteorites AN - 51774342; 2005-002390 AB - Our analyses of high quality spectra of several S-type asteroids (17 Thetis, 847 Agnia, 808 Merxia, and members of the Agnia and Merxia families) reveal that they include both low- and high-calcium pyroxene with minor amounts of olivine ( approximately 0.4. High-calcium pyroxene is a spectrally detectable and petrologically important indicator of igneous history and may prove critical in future studies aimed at understanding the history of asteroidal bodies. The silicate mineralogy inferred for Thetis and the Merxia and Agnia family members requires that these asteroids experienced igneous differentiation, producing broadly basaltic surface lithologies. Together with 4 Vesta (and its smaller "Vestoid" family members) and the main-belt asteroid 1489 Magnya, these new asteroids provide strong evidence for igneous differentiation of at least five asteroid parent bodies. Based on this analysis of a small subset of the near-infrared asteroid spectra taken to date with SpeX at the NASA IRTF, we expect that the number of known differentiated asteroids will increase, consistent with the large number of parent bodies inferred from studies of iron meteorites.

Gusev is hypothesized to be the site of a former lake, but no clear evidence for lacustrine sedimentation has been found to date. Instead, the dominant lithology is basalt, and the dominant geologic processes are impact events and eolian transport. Many rocks exhibit coatings and other characteristics that may be evidence for minor aqueous alteration. Any lacustrine sediments that may exist at this location within Gusev apparently have been buried by lavas that have undergone subsequent impact disruption.

The composition of soils is similar to those at previous landing sites, as a result of global mixing and distribution by dust storms. Rocks (fresh surfaces exposed by the rock abrasion tool) resemble volcanic rocks of primitive basaltic composition with low intrinsic potassium contents. High abundance of bromine (up to 170 parts per million) in rocks may indicate the alteration of surfaces formed during a past period of aqueous activity in Gusev crater.

Pancam and Mini-Thermal Emission Spectrometer (Mini-TES) spectra suggest that all of these rocks are similar but have variable coatings and dust mantles. Magnified images of brushed and abraded rock surfaces show alteration rinds and veins. Rock interiors contain < or =25% megacrysts. Chemical analyses of rocks by the Alpha Particle X-ray Spectrometer are consistent with picritic basalts, containing normative olivine, pyroxenes, plagioclase, and accessory FeTi oxides. Mossbauer, Pancam, and Mini-TES spectra confirm the presence of olivine, magnetite, and probably pyroxene. These basalts extend the known range of rock compositions composing the martian crust.

Weakly bound agglomerates of dust are present in the soil near the Columbia Memorial Station. Some of the brushed or abraded rock surfaces show igneous textures and evidence for alteration rinds, coatings, and veins consistent with secondary mineralization. The rock textures are consistent with a volcanic origin and subsequent alteration and/or weathering by impact events, wind, and possibly water.

Optically thick coatings of fine-grained ferric iron-rich dust dominate most bright soil and rock surfaces. Spectra of some darker rock surfaces and rock regions exposed by brushing or grinding show near-infrared spectral signatures consistent with the presence of mafic silicates such as pyroxene or olivine. Atmospheric observations show a steady decline in dust opacity during the mission, and astronomical observations captured solar transits by the martian moons, Phobos and Deimos, as well as a view of Earth from the martian surface.

Emission of this powerful greenhouse gas from wetlands is known to depend on climate, with increasing temperature and rainfall both expected to increase methane emissions. This study, combining our field and controlled environment manipulation studies in Europe and North America, reveals an additional control: an emergent pattern of increasing suppression of methane (CH (sub 4) ) emission from peatlands with increasing sulfate (SO (super 2-) / (sub 4) -S) deposition, within the range of global acid deposition. We apply a model of this relationship to demonstrate the potential effect of changes in global sulfate deposition from 1960 to 2080 on both northern peatland and global wetland CH (sub 4) emissions. We estimate that sulfur pollution may currently counteract climate-induced growth in the wetland source, reducing CH (sub 4) emissions by nearly equal 15 Tg or 8% smaller than it would be in the absence of global acid deposition. Our findings suggest that by 2030 sulfur pollution may be sufficient to reduce CH (sub 4) emissions by 26 Tg or 15% of the total wetland source, a proportion as large as other components of the CH (sub 4) budget that have until now received far greater attention. We conclude that documented increases in atmospheric CH (sub 4) concentration since the late 19th century are likely due to factors other than the global warming of wetlands.

Impacts ejected basaltic rocks that probably were part of locally formed lava flows from at least 10 meters depth. Some rocks have been textured and/or partially buried by windblown sediments less than 2 millimeters in diameter that concentrate within shallow, partially filled, circular impact depressions referred to as hollows. The terrain traversed during the 90-sol (martian solar day) nominal mission shows no evidence for an ancient lake in Gusev crater.

Two sextets resulting from nonstoichiometric magnetite are also present, except for a coating on the rock Mazatzal, where a hematite-like sextet is present. Greater proportions of ferric-bearing phases are associated with undisturbed soils and rock surfaces as compared to fresh rock surfaces exposed by grinding. The ubiquitous presence of olivine in soil suggests that physical rather than chemical weathering processes currently dominate at Gusev crater.

Orientations of these features suggest formative winds from the north-northwest, consistent with predictions from atmospheric models of afternoon winds in Gusev Crater. Cuttings from the rover Rock Abrasion Tool are asymmetrically distributed toward the south-southeast, suggesting active winds from the north-northwest at the time (midday) of the abrasion operations. Characteristics of some rocks, such as a two-toned appearance, suggest that they were possibly buried and exhumed on the order of 5 to 60 centimeters by wind deflation, depending on location.

Undisturbed soil spectra show evidence for minor carbonates and bound water. Rocks are olivine-rich basalts with varying degrees of dust and other coatings. Dark-toned soils observed on disturbed surfaces may be derived from rocks and have derived mineralogy (+ or -5 to 10%) of 45% pyroxene (20% Ca-rich pyroxene and 25% pigeonite), 40% sodic to intermediate plagioclase, and 15% olivine (forsterite 45% + or -5 to 10). Two spectrally distinct coatings are observed on rocks, a possible indicator of the interaction of water, rock, and airfall dust. Diurnal temperature data indicate particle sizes from 40 to 80 mu m in hollows to approximately 0.5 to 3 mm in soils.

A conceptual power system architecture was defined and design points were generated for several system voltages using state-of-the-art or advanced technologies. A 300-V 'direct-drive' architecture was also analyzed to assess the benefits of directly powering the electric thruster from the photovoltaic array without up-conversion. Computational models were exercised to predict the performance and size power system components to meet spacecraft mission requirements. Pertinent space environments were calculated for the mission trajectory and an electron current collection model was developed to estimate photovoltaic array losses due to natural and induced plasma environments. The secondary benefits of power system mass savings for spacecraft propulsion and attitude control systems were also quantified. Results indicate that considerable spacecraft wet mass savings were achieved by the 300-V and 300-V direct-drive architectures.

Once deforested, these lands continue to be sources of substantial burning emissions for many years due to frequent pasture burning. The objective of this research was to quantify biomass-burning emissions at a local scale. We estimated carbon emissions from three sources: fires associated with primary forest slash, regenerating forest slash, and pastures. The study was conducted on a 94 370-ha section of land surrounding Jamari, Rondonia, Brazil. In the emissions computation, we integrated site-specific, ground-based data (biomass, emission factors for flaming and smoldering combustion, and combustion factors for land-cover types) with a Landsat TM land cover change map of the study area for 1984-1992. This map was used to ascertain changes in land cover based on TM image dates during a period of early colonization and rapid deforestation in Rondonia. Emissions of CO, CO sub(2), CH sub(4), and other hydrocarbon trace gases were calculated. Between 1984 and 1992, we found CO sub(2) emissions generated by primary forest slash burning were 694 379 Mg C (920 kg C times ha super(-1) times yr super(-1)) and regenerating forest slash burning contributed 23 436 Mg C (31 kg C times ha super(-1) times yr super(-1)), whereas cumulative pasture burning produced 238 180 Mg C (316 kg C times ha super(-1) times yr super(-1)). CO and CH sub(4) followed the same trends by land cover type. Primary forest slash burns contributed 73% of the total C emissions whereas burning regenerating forest slash and pasture produced 2% and 25%, respectively. The major finding of this work is the identification of pasture burning as a potentially important source of pyrogenic emissions, but better data on biomass and combustion efficiency could confirm this finding. Further we demonstrated a novel method for estimating area burned that links land cover type and change to burn frequency.

In shallow (1.65 g/cm super(3)) C pools decreased from 25 Mg/ha in the least disturbed watershed to 3 Mg/ha in the most disturbed watershed; whereas light-fraction C pools were similar (4-6 Mg/ha) across all watersheds. Soil C stocks decreased from 216 Mg/ha in the least disturbed watershed to 157 Mg/ha in the most disturbed watersheds. Evidence was found that mobile organic carbon transported in soil water accumulated in mineral horizons principally through sorption to mineral particles. Strong association with mineral particles was greater in the thicker, presumably older, illuvial horizons. We found light amorphous material in some of these thicker illuvial horizons, suggesting that mobile organic carbon may have been immobilized through flocculation of metal-bearing organic acids. Watersheds that experienced more intense soil mixing from windthrow had lower levels of strongly humified soil organic matter, and more in a partially decomposed particulate form.

In these perplexing cases the synoptic situation can superficially look similar to cases in which very little precipitation occurs. An example is the major precipitation and flooding event that affected Piedmont, Italy, between 13 and 16 October 2000. The emphasis of this study is on the moisture origin and transport. Moisture balances are computed on different space and time scales, revealing that precipitation exceeds evaporation over an area inclusive of Piedmont and the northwestern Mediterranean region, on a time scale encompassing the event and about 2 weeks preceding it. This is suggestive of an important moisture contribution originating from outside the region. A synoptic and dynamic analysis is then performed to outline the potential mechanisms that could have contributed to the large-scale moisture transport. The central part of the work uses a quasi-isentropic water vapor back-trajectory technique. The moisture sources obtained by this technique are compared with the results of the balances and with the synoptic situation to unveil possible dynamic mechanisms and physical processes involved. It is found that moisture sources on a variety of atmospheric scales contribute to this event. First, an important contribution is caused by the extratropical remnants of former Tropical Storm Leslie. The large-scale environment related to this system allows a significant amount of moisture to be carried toward Europe. This happens on a time scale of about 5-15 days preceding the Piedmont event. Second, water vapor intrusions from the African intertropical convergence zone and evaporation from the eastern Atlantic contribute on the 2-5-day time scale. The large-scale moist dynamics appears therefore to be one important factor enabling a moderate Mediterranean cyclone to produce heavy precipitation. Finally, local evaporation from the Mediterranean, water vapor recycling, and orographically induced low-level convergence enhance and concentrate the moisture over the area where heavy precipitation occurs. This happens on a 12-72-h time scale.

However, understanding the relationship between canopy structure and function has been limited by a paucity of methods for determining structure at scales consistent with those of function measurements. We describe here a portable system, assembled from commercially available components, for acquiring measurements of distances to overhead plant surfaces. These measurements can be aggregated to assess canopy structure rapidly at scales of ecological interest. Deployed from the forest floor, the system includes a narrow-beam rapidly pulsed first-return laser rangefinder coupled with a data recording system. Tests in an age sequence of broad-leaved closed-canopy forests showed that the system provides results significantly more rapidly than previous methods, at spatial scales as small as 1 m in all dimensions. The estimated mean vertical canopy structure is consistent with that found from more laborious, manual approaches, such as the foliage height profile method. The system has some biases due to beam width and range averaging but, from a variety of tests, we found these have relatively little effect on the structure estimates. Various field sampling schemes and methods of aggregating the measurements yield a variety of representations of structure, including mean profiles, tomographic sections, three-dimensional distributions of canopy surface density and maximum height surfaces. Derivable summary measures include canopy cover and area index, porosity, the size distribution of overhead openings and indices of structural complexity. Moreover, the approach can provide estimates of spatial variability and covariance not previously obtainable. Synthesis and applications. Portable light detection and ranging (LIDAR) systems, such as the one we describe here, provide a new tool for rapid measurement of small-scale forest structure. These can contribute efficiently and relatively inexpensively to canopy research and forestry programmes, covering a range of ecological and production needs.

The study areas, ranging in size from 600 to 10 000 km super(2), include communities that practice a range of land uses from small-scale, rotational agriculture to long-term pasture. Carbon emissions from deforestation were estimated based on rates of deforestation derived from Landsat satellite data and published estimates of mature forest biomass. Estimates of carbon uptake by secondary forest regrowth were based on area estimates from the satellite data and biomass estimates from field surveys. Estimates of carbon emissions from the clearance of secondary forest were included. The total carbon emissions were partitioned into that immediately released by biomass burning during clearance and that from subsequent decomposition and burning of felled biomass. A range of net carbon fluxes from secondary forest regrowth and clearance was estimated by extrapolating land-use patterns in each study area to the entire area of deforested landscape in Amazonian Brazil and Bolivia, and by varying average biomass accumulation rate of regrowing forest and fallow period. Over 60 km super(2) of forest were cleared from 1988 to 1995 in each of the Brazilian study areas, and over 940 km super(2) were cleared from 1986 to 1996 in the Bolivian study area. This resulted in 30-200 Mg C/yr emitted from biomass burning during deforestation. If the carbon that is committed to subsequent burning and decomposition of felled biomass is included, total committed emissions of 75-650 Mg C/yr resulted from deforestation in each study area. The carbon uptake by secondary forests was 33-435 Mg C/yr. However, emissions from the reclearance of secondary forests were nearly as large: 17-365 Mg C/yr. Extrapolation of these results to the Brazilian and Bolivian Amazon suggests that, at the national level, carbon uptake by secondary forests offset less than one-fifth of the carbon emissions from deforestation. Despite differences in land-use pattern, average fallow period, and rate of biomass accumulation used in the extrapolation, net carbon uptake by secondary forests was consistently small when compared to the total emissions from deforestation.

Simulated soil moisture profile retrievals were made by assimilating near- surface soil moisture observations with various accuracy (0, 1, 2, 3, 4, 5 and 10%v/v standard deviation) repeat time (1, 2, 3, 5, 10, 15, 20 and 30 days), and spatial resolution (0.5, 6, 12 18, 30, 60 and 120 arc-min). This study found that near-surface soil moisture observation error must be less than the model forecast error required for a specific application when used as data assimilation input, else slight model forecast degradation may result. It also found that near-surface soil moisture observations must have an accuracy better than 5%v/v to positively impact soil moisture forecasts, and that daily near- surface soil moisture observations achieved the best soil moisture and evapotranspiration forecasts for the repeat times assessed, with 1-5 day repeat times having the greatest impact. Near-surface soil moisture observations with a spatial resolution finer than the land surface model resolution (~30 arc-min) produced the best results, with spatial resolutions coarser than the model resolution yielding only a slight degradation. Observations at half the land surface model spatial resolution were found to be appropriate for our application. Moreover, it was found that satisfying the spatial resolution and accuracy requirements was much more important than repeat time.

AN - 36373684; 10906-040358_0001 AB - PURPOSE: The construction, installation, and operation of four to six Outrigger Telescopes (OTs) near the twin Keck Telescopes at the W.M. Keck Observatory site within the Mauna Kea Science Reserve on the island of Hawaii are proposed by the National Aeronautics and Space Administration (NASA). OTs are interferometers, representing critical technology for overcoming the limitations of single telescopes, which is that the sharpness, or amount of image detail, is limited by the size of the telescope's main mirror. An interferometer combines two or more telescopes optically so that they functions if they were a single larger telescope. The number of individual telescopes and the distances between them determines the sharpness of the image from an interferometer. Interferometers can measure positions of stars with extreme accuracy, enabling them to locate planets revolving those stars. The OTs will be used to detect thermal dust emissions from dust clouds around stars detect the light from and characterize the atmospheres of hot, Jupiter-mass planets located within 12 million miles of the stars they are orbiting, detect the astrometric signature of planets as small as Uranus, make images of proto-stellar disks, provide high-resolution information about some faint objects outside our galaxy, and make high-resolution observations of objects within the solar system, including asteroids, comets, and outer planets. It is anticipated that on-site installation of four of the six OTs, along with on-site construction of underground structures for the fifth and six telescopes, would begin in 2005, with operations planned to begin in 2007. Even if adequate funding becomes available, the fifth and sixth telescopes would begin above-ground construction no earlier than 2007. In addition to the proposed action, this draft EIS considers a No Action Alternative an alternative site on the Canary Islands and two sites in California; the Canary Island and California alternatives could lead NASA to provide for four OTs. POSITIVE IMPACTS: The OTs would provide invaluable data about stars, planets, and other astronomical objects and generally advance the instrumental science of interferometry. NEGATIVE IMPACTS: Major impacts of concern would be those to cultural resource sites the visual integrity of the summit region of Mauna Kea, and displacement of a small extent of habitat for the Wekiu bug, a candidate for listing under the Endangered Species Act. The Hawaii Historic Preservation Division believes that Kukahua'ula, the area of the three summit cones of Mauna Kea, meets the criteria for listing in the National Register of Historic Places, primarily due its importance as a traditional cultural property. Some Hawaiians have identified the larger area of Mauna Kea, from the 6,000-foot to the summit, as a sacred landscape valued for its spiritual significance.

AN - 16349383; 10906 AB - PURPOSE: The construction, installation, and operation of four to six Outrigger Telescopes (OTs) near the twin Keck Telescopes at the W.M. Keck Observatory site within the Mauna Kea Science Reserve on the island of Hawaii are proposed by the National Aeronautics and Space Administration (NASA). OTs are interferometers, representing critical technology for overcoming the limitations of single telescopes, which is that the sharpness, or amount of image detail, is limited by the size of the telescope's main mirror. An interferometer combines two or more telescopes optically so that they functions if they were a single larger telescope. The number of individual telescopes and the distances between them determines the sharpness of the image from an interferometer. Interferometers can measure positions of stars with extreme accuracy, enabling them to locate planets revolving those stars. The OTs will be used to detect thermal dust emissions from dust clouds around stars detect the light from and characterize the atmospheres of hot, Jupiter-mass planets located within 12 million miles of the stars they are orbiting, detect the astrometric signature of planets as small as Uranus, make images of proto-stellar disks, provide high-resolution information about some faint objects outside our galaxy, and make high-resolution observations of objects within the solar system, including asteroids, comets, and outer planets. It is anticipated that on-site installation of four of the six OTs, along with on-site construction of underground structures for the fifth and six telescopes, would begin in 2005, with operations planned to begin in 2007. Even if adequate funding becomes available, the fifth and sixth telescopes would begin above-ground construction no earlier than 2007. In addition to the proposed action, this draft EIS considers a No Action Alternative an alternative site on the Canary Islands and two sites in California; the Canary Island and California alternatives could lead NASA to provide for four OTs. POSITIVE IMPACTS: The OTs would provide invaluable data about stars, planets, and other astronomical objects and generally advance the instrumental science of interferometry. NEGATIVE IMPACTS: Major impacts of concern would be those to cultural resource sites the visual integrity of the summit region of Mauna Kea, and displacement of a small extent of habitat for the Wekiu bug, a candidate for listing under the Endangered Species Act. The Hawaii Historic Preservation Division believes that Kukahua'ula, the area of the three summit cones of Mauna Kea, meets the criteria for listing in the National Register of Historic Places, primarily due its importance as a traditional cultural property. Some Hawaiians have identified the larger area of Mauna Kea, from the 6,000-foot to the summit, as a sacred landscape valued for its spiritual significance. Moreover, the area is a potentially rich site of archaeological information. LEGAL MANDATES: National Historic Preservation Act of 1966 (16 U.S.C. 470 et seq.)

[Part 1 of 1] T2 - INTERNATIONAL SPACE RESEARCH PARK AT THE JOHN F. KENNEDY SPACE CENTER, BREVARD COUNTY, FLORIDA. AN - 36372598; 10883-040333_0001 AB - PURPOSE: The development of the International Space Research Park (ISRP) at the John F. Kennedy Space Center (KSC), Brevard County, Florida is proposed to bring new research and development uses to the KSC. The National Aeronautics and Space Administration (NASA) has entered into an agreement with the state of Florida, through the Florida Space Authority, to undertake a joint study into the development of up to 400 acres of land on KSC for the purposes of creating the research park. KSC encompasses 139,490 acres of land within Brevard and Volusia counties. The study area analyzed for the purposes of this proposal includes KSC, Brevard County and the five adjoining counties. Three alternatives, including a No Action Alternative (Alternative 3), are considered in this final EIS. All alternative ISRP sites are located on KSC along the south portion of the Kennedy Parkway South (State Road 3), the major north-south transportation arterial through KSC into Merritt Island and Titusville. Action Alternative 1, which is the preferred alternative, would develop the ISRP on land located immediately south of the KSC visitors Complex along Space Commercial Way on a site that is dominated by citrus groves and includes remnant wetlands and disturbed habitats. Action Alternative 2 would develop the ISRP on land located approximately 321 acres northeast of the KSC south security gate on Kennedy Parkway South near B Avenue Southwest (Tel-4 Road); this site, east of Kennedy Parkway, is an undeveloped landscape characterized by high quality scrub and wetlands. Both alternatives 1 and 2 could include the development of 24 acres east of Space Commercial Way within an existing citrus grove. POSITIVE IMPACTS: The ISRP would provide for complementary research and development objectives, Camp Canaveral Spaceport mission enhancement, public-private partnership opportunities, and space commercialization and development. As a center for research and development, the research park would bring together a dynamic mix of industry, academic, and government researchers to focus their combined strengths in areas of research critical to the long-term success of NASA and its partners. NEGATIVE IMPACTS: Under the preferred alternative, construction of the ISRP would change soil composition, structure, and function within the specific initial construction and development site due to the movement and addition of soils. Filling of jurisdictional wetlands would be required, eliminating the functional attributes of these regulated habitats and violating state and federal requirements with respect to wetlands. The cumulative impacts of habitat fragmentation from habitat loss and introduction of new roads and the increase human presence could increase mortality and/or harassment of numerous individual indigo snakes, a federally protected species.

AN - 72016666; 15194782 AB - Ex vivo human immunodeficiency virus type 1 (HIV-1) infection of human lymphoid tissue recapitulates some aspects of in vivo HIV-1 infection, including a severe depletion of CD4(+) T cells and suppression of humoral immune responses to recall antigens or to polyclonal stimuli. These effects are induced by infection with X4 HIV-1 variants, whereas infection with R5 variants results in only mild depletion of CD4(+) T cells and no suppression of immune responses. To study the mechanisms of suppression of immune responses in this ex vivo system, we used aldrithiol-2 (AT-2)-inactivated virions that have functional envelope glycoproteins but are not infectious and do not deplete CD4(+) T cells in human lymphoid tissues ex vivo. Nevertheless, AT-2-inactivated X4 (but not R5) HIV-1 virions, even with only a brief exposure, inhibit antibody responses in human lymphoid tissue ex vivo, similarly to infectious virus. This phenomenon is mediated by soluble immunosuppressive factor(s) secreted by tissue exposed to virus.

AN - 67301006; 16231455 AB - The aim of this study was to evaluate the association of plasma epinephrine (EPI) and norepinephrine (NE) responses to insulin induced hypoglycemia (ITT) 3 weeks before the space flight (SF), on the 5th day of SF, on the 2nd and 16th days after the landing in the first Slovak astronaut, and before and on the 5th day of prolonged subsequent head-down (-6 degrees) bed rest (BR) in 15 military aircraft pilots. Blood samples during the test were collected via cannula inserted into cubital vein, centrifuged in the special appliance Plasma-03, frozen in Kryogem-03, and at the end of the 8-day space flight transferred to Earth in special container for hormonal analysis. Insulin hypoglycemia was induced by i.v. administration of 0.1 IU/kg BW insulin (Actrapid HM) in bolus. Insulin administration led to a comparable hypoglycemia in pre-flight, in-flight conditions and before and after bed rest. ITT led to a pronounced increase in EPI levels and moderate increase in NE in pre-flight studies. However, an evidently reduced EPI response was found after insulin administration during SF and during BR. Thus, during the real microgravity in SF and simulated microgravity in BR, insulin-induced hypoglycemia activates the adrenomedullary system to less extent than at conditions of the Earth gravitation. Post-flight changes in EPI and NE levels did not significantly differ from those of pre-flight since SF was relatively short (8 days) and the readaptation to Earth gravitation was fast. It seems, that an increased blood flow in brain might be responsible for the reduced EPI response to insulin. Responses to ITT in physically fit subjects indicate the stimulus specificity of deconditioning effect of 5 days bed rest on stress response. Thus, the data indicate that catecholamine responses to ITT are reduced after exposure to real as well as simulated microgravity.

Ground-based experiments have shown that the examination of target cell lysis after incubation with NK cells is a simple and informative model for studying the influence of microgravity. NK cytotoxicity was measured as the value of non-degradeted labeled myeloblasts (K-562) after 24 hrs exposure with human lymphocytes in suspension. A special device was developed for space flight experiments. Human cultured lymphocytes and labeled K-562 cells were loaded into special syringes and delivered to the Russian segment of the ISS. Cosmonauts prepared co-cultured suspensions during the first day of microgravity, exposed them at 37 degrees C for 24 hrs and then separated H3-labeled cells on special filters. The results of ISS-8 mission showed that human NK cells in vitro remain lysis activity toward target cells in microgravity. The basal level of NK cytotoxicity was low and we did not found significant differences between "control" and "flight" values. Interferon production during the interaction between immune and target cells (ratio 10:1) in microgravity did not differ compared with ground-based control experiments. Ground exposure of the same lymphocyte samples with K-562 cells to 24 hrs clinorotation also did not lead to significant differences. These experiments paved the way for understanding the cell interaction mechanisms in space flight and the obtained results suggest that microgravity does not disrupt the interaction of NK cells with tumor cells.

AN - 67294737; 16231450 AB - A group of 18 healthy male subjects (25-45 y.o.) participated in the studies of +8.3 Gx tolerance (profile of ballistic reentry) and +Gz tolerance (up to physiological limit) before and after pharmacological hypohydration of organism. Moderate hypohydration was carried out by one 40 mg Furosemid (Lasix) dose, or by pharmacological complex: Furosemid (40 mg) + Hypothiazide (25 mg) + Triamteren (50 mg). Subjects removed with urine about 2 l of water, that was accompanied by increase excretion of electrolytes and caused reduction of the body mass by 2.0 +/- 0.2% and diminution of the plasma volume by 13.5% +/- 2.0%. Pharmacological hypohydration does not lead to a substantial loss in +Gx tolerance. No pathological signs, limiting +Gx tolerance up to 8.3 g were found. The longitudinal +Gz tolerance was less, than +Gx one. The limit of achieved +Gz loads after diuretics reduced by 0.6 g. The scientific and applied significance of this research is that diuretics can be safety used in pre-launch period to prevent the negative effects associated with initial phase of space flight. Besides the preliminary intake of diuretics promotes to diminish of discomfort of cosmonauts, reducing urination in a period of prelaunch waiting in spacecraft.

Barrier sand and deltaic mud sequences illustrate a process by which potential ground water and hydrocarbon reservoir rocks accumulated unusually rapidly and were preserved. Set against decelerating Holocene sea-level rise and locally variable subsidence rates, the study provides an example of the interplay between an emerging, prograding, and partially stranded barrier island chain, a sizable estuary, and several extensive delta lobes. Utilizing microfossil fauna-based depositional facies information and archaeological data, absolute dates helped to reconstruct the history of the Alabama-Louisiana barrier chain and deltas between ca. 5.7 and ca. 1.5 (super 14) C ka BP. Protected by the substantial dune cover that prevented island submersion, the regional eustastic transgression paradoxically was synchronous with significant progradational barrier and deltaic regression. The earliest barrier islands emerged ca. 4.6-4.4 (super 14) C ka BP (ca. 5.7-5.0 cal years) when sea level stood at ca. -1.0 to -1.5 m. These islands isolated Mississippi Sound from the greater Gulf of Mexico. The absence of a lagoonal-inshore sediment interval beneath the islands and the 3-15 m thick basal nearshore marine muddy-sandy unit that blankets the Pleistocene surface refutes the transgressive history of barrier initiation. The islands aggraded on a 3.0-16.5 m thick fine sandy shallow-marine regressive platform lithosome that, in turn, overlies a transgressive muddy-sandy nearshore marine lower sediment interval. Avulsion of the Mississippi River had abruptly reduced nearshore salinities by ca. 3.9-3.7 ka (super 14) C BP. Renewed Mississippi delta growth induced rapid aggradation and progradation on the opposite Pearl River delta-mainland shore as well. Gulf influences have rapidly diminished in areas so affected. A new absolute chronology of the Mississippi-St. Bernard delta lobes constrains these events. Delta growth and mainland progradation first isolated, then severely constricted the Lake Borgne embayment. Accompanied by ongoing subsidence, the western barriers were stranded, then buried. Shoaling, related to St. Bernard delta progradation, interfered with westward littoral drift to maintain Cat Island. Archaeology provided important supplementary data for dating environmental changes. Refuting earlier suggestions that Native colonization rapidly followed delta complex formation, the earliest known Indian sites postdated the start of the associated St. Bernard delta lobe by 1.9-3.1 (super 14) C ka.

The Re-Pt-Os isotopic data for five cumulate samples yield Re-Os and Pt-Os isochrons with ages of 2725+ or -33 and 2956+ or -760 Ma and initial (super 187) Os/ (super 188) Os=0.10902+ or -16 and (super 186) Os/ (super 188) Os=0.1198318+ or -18, respectively. These ages are consistent with the time of lava emplacement determined by other geochronometers. The initial (super 187) Os/ (super 188) Os isotopic composition of the Pyke Hill source is similar to the (super 187) Os/ (super 188) Os isotopic compositions of enstatite and ordinary chondrites and to that of PUM at 2725 Ma. Using the Pt-Os isotopic data for the Pyke Hill source, the present-day (super 186) Os/ (super 188) Os isotopic composition of PUM was calculated to be 0.1198387+ or -18. The regression of global (super 187) Os/ (super 188) Os isotopic data for terrestrial materials shown to represent Os isotopic composition of the contemporary mantle indicates that the LILE-depleted mantle evolved from the solar system starting composition and, over Earth's history, was on average approximately 8% depleted in Re vs. Os relative to PUM. From the HSE composition of the emplaced Pyke Hill komatiite lava, the mantle source was inferred to contain Re (0.30 ppb), Os (3.9 ppb), Ir (3.6 ppb), Ru (5.4 ppb), Pt (6.4 ppb), and Pd (6.3 ppb) in relative proportions similar to those in average enstatite chondrites, except for Pd, which was enriched over Pt by approximately 30% in the Pyke Hill source compared to enstatite chondrites. From these data, the (super 190) Pt/ (super 188) Os of PUM was calculated to be 0.00157. If the HSE abundances in the terrestrial mantle were inherited from chondritic material of a late veneer, the latter should have had the HSE composition of ordinary or enstatite chondrites. Alternatively, if the reenrichment of the mantle with HSE was the result of an open-system transport of material across the core-mantle boundary, it was likely a global event that should have occurred shortly after core formation.

It builds on the recent Intergovernmental Panel on Climate Change (IPCC) Special Report on Emissions Scenarios (SRES), but has been created independently of that report. The SRES scenarios are derived from projected data on economic, demographic, technological and land-use changes for the 21st century in a highly aggregated form consisting of four world regions. Since analysts often need socio-economic data at higher spatial resolutions that are consistent with GCM climate scenarios, we undertook linear downscaling to 2100 of population and GDP to the country level of the aggregated SRES socio-economic data for four scenario families: A1, A2, B1, B2. Using these country-level data, we also generated geo-spatial grids at 1/4 degree resolution (30 km at the equator) for population "density" (people/unit land area) and for GDP "density" (GDP/unit land area) for two time slices, 1990 and 2025. This paper provides background information for the databases, including discussion of the data sources, downscaling methodology, data omissions, discrepancies with the SRES report, problems encountered, and areas needing further work.

For the coastal region between the Bering and Malaspina Glaciers, the average ice mass thickness changes between 1995 and 2000 range from 1 to 5 m/year. These ice changes caused solid Earth displacements in our study region with predicted values of -10 to 50 mm in the vertical and predicted horizontal displacements of 0-10 mm at variable orientations. Relative to stable North America, observed horizontal rates of tectonic deformation range from 10 to 40 mm/year to the north-northwest and the predicted tectonic uplift rates range from approximately 0 mm/year near the Gulf of Alaska coast to 12 mm/year further inland. The ice mass changes between 1995 and 2000 resulted in discernible changes in the Global Positioning System (GPS) measured station positions of one site (ISLE) located adjacent to the Bagley Ice Valley and at one site, DON, located south of the Bering Glacier terminus. In addition to modifying the surface displacements rates, we evaluated the influence ice changes during the Bering glacier surge cycle had on the background seismic rate. We found an increase in the number of earthquakes (M sub(L)>=2.5) and seismic rate associated with ice thinning and a decrease in the number of earthquakes and seismic rate associated with ice thickening. These results support the hypothesis that ice mass changes can modulate the background seismic rate. During the last century, wastage of the coastal glaciers in the Icy Bay and Malaspina region indicates thinning of hundreds of meters and in areas of major retreat, maximum losses of ice thickness approaching 1 km. Between the 1899 Yakataga and Yakutat earthquakes (M sub(w)=8.1, 8.1) and prior to the 1979 St. Elias earthquake (M sub(s)=7.2), the plate interface below Icy Bay was locked and tectonic strain accumulated. We used estimated ice mass change during the 1899-1979 time period to calculate the change in the fault stability margin (FSM) prior to the 1979 St. Elias earthquake. Our results suggest that a cumulative decrease in the fault stability margin at seismogenic depths, due to ice wastage over 80 years, was large, up to 2 MPa. Ice wastage would promote thrust faulting in events such as the 1979 earthquake and subsequent aftershocks.

Low strain rates imply that the Ross Sea rift is either inactive or active at a very low rate. This result indicates that the two subcontinents are likely joined as a single coherent lithospheric plate. They could have been joined since the end of Adare Trough spreading in Oligocene time. The volcanic activity in the Ross Sea sector at present such as at Mount Erebus is most likely related to mantle upwelling and not associated with continental rifting. GPS measurements of vertical rates indicate postglacial rebound of up to 12+/-4 mm/year in western Marie Byrd Land (wMBL). Errors are scaled 1[sigma]. The rock uplift rates are consistent with postglacial rebound models of significant ice thinning in the eastern Ross Ice Shelf in the late Holocene.

Humans have settled primarily in coastal regions putting tremendous stress on coastal aquatic systems. The Indian River Lagoon (IRL), located along Florida's Atlantic coast, is one of North America's most diverse estuaries surrounded by a rapidly growing human population. To quantify changes that have occurred within the watershed, we produced landcover maps representing the northern portion of the Indian River Lagoon watershed for 1920, 1943, and 1990. The 1943 and 1990 maps were generated by photo interpretation and the 1920 map was produced by spatial modeling techniques. All anthropogenic landcover types increased throughout the study period, while all native landcover types decreased, with the exception of hammocks. The dominant, terrestrial landcover types in 1920 were flatwoods, scrub, and freshwater marsh. In 1943, flatwoods and scrub types were still dominant, but agriculture was the third most abundant type. In 1990 urban became the dominate landcover with flatwoods second and agriculture third. The remaining natural areas have been highly fragmented by roads, canals, and urban areas. Shoreline composition has changed, with 1% of the Indian River Lagoon study shoreline being comprised of urban in 1920 and 26% in 1990. This dataset is useful for identifying changes in functional landcover, which will help improve the management of resources within the IRL watershed and support important ecological studies investigating the relationships between nature and anthropogenic influences.

To determine whether saturation diving has nutrition-related effects similar to those of spaceflight, we conducted a clinical nutritional assessment of the NEEMO crew (4 men, 2 women) before, during, and after their 14-d saturation dive. Blood and urine samples were collected before, during, and after the dive. The foods consumed by the crew were typical of the spaceflight food system. A number of physiologic changes were observed, during and after the dive, that are also commonly observed during spaceflight. Hemoglobin and hematocrit were lower (P < 0.05) after the dive. Transferrin receptors were significantly lower immediately after the dive. Serum ferritin increased significantly during the dive. There was also evidence indicating that oxidative damage and stress increased during the dive. Glutathione peroxidase and superoxide dismutase decreased during and after the dive (P < 0.05). Decreased leptin during the dive (P < 0.05) may have been related to the increased stress. Subjects had decreased energy intake and weight loss during the dive, similar to what is observed during spaceflight. Together, these similarities to spaceflight provide a model to use in further defining the physiologic effects of spaceflight and investigating potential countermeasures.

A particularly compelling measure of humanity's cumulative impact is the fraction of the planet's net primary production that we appropriate for our own use. Net primary production--the net amount of solar energy converted to plant organic matter through photosynthesis--can be measured in units of elemental carbon and represents the primary food energy source for the world's ecosystems. Human appropriation of net primary production, apart from leaving less for other species to use, alters the composition of the atmosphere, levels of biodiversity, energy flows within food webs and the provision of important ecosystem services. Here we present a global map showing the amount of net primary production required by humans and compare it to the total amount generated on the landscape. We then derive a spatial balance sheet of net primary production 'supply' and 'demand' for the world. We show that human appropriation of net primary production varies spatially from almost zero to many times the local primary production. These analyses reveal the uneven footprint of human consumption and related environmental impacts, indicate the degree to which human populations depend on net primary production 'imports' and suggest policy options for slowing future growth of human appropriation of net primary production.

A heat shock at 42C maximized survival at the lethal temperature of 52C and a cold shock at 20C maximized survival after repeated freeze-thawing. Enhanced survival from heat shock was found to be strongly dependent on growth stage, with its greatest effect shortly after phase. Increased synthesis of a total of 67 proteins during heat shock and 42 proteins during cold shock were observed by two-dimensional polyacrylamide gel electrophoresis (2D PAGE) and autoradiography. Eight of the most highly induced heat shock proteins shown by 2D PAGE were identified by MALDI-MS as Hsp20, GroEL, DnaK, SodA, Csp, Protease I and two proteins of unknown function.

AN - 67303046; 15920847 AB - To develop a ground-based experimental facility for microorganism waste processing, which will be used to recover nutrient from plant inedible biomass essential for growth and development of plants. After technical parameters and performance requirements were defined, planning demonstration, drawing design, fabrication, debug and plant inedible residue-biodegradation tests by microorganisms were conducted. The facility worked well, and the parameters, such as energy consumption, volume and weight, met the design requirement. The water-treated quality and the ability of treating plant residual by microorganism were better than the demands. The ground-based results demonstrated that total organic carbon (TOC) degradation above 92.1%, and chemical oxygen demand (COD) reduction over 95.5% could be maintained. The facility has reasonable technical indexes, and smooth and reliable performances. Its major working principle is suitable for the demand of space conditions. It is capable of being utilized for biodegradation of plant inedible biomass in space.

AN - 67301853; 15875356 AB - A miniature electronic nose (ENose) has been designed and built at the Jet Propulsion Laboratory (JPL), Pasadena, CA, and was designed to detect, identify, and quantify ten common contaminants and relative humidity changes. The sensing array includes 32 sensing films made from polymer carbon-black composites. Event identification and quantification were done using the Levenberg-Marquart nonlinear least squares method. After successful ground training, this ENose was used in a demonstration experiment aboard STS-95 (October-November, 1998), in which the ENose was operated continuously for six days and recorded the sensors' response to the air in the mid-deck. Air samples were collected daily and analyzed independently after the flight. Changes in shuttle-cabin humidity were detected and quantified by the JPL ENose; neither the ENose nor the air samples detected any of the contaminants on the target list. The device is microgravity insensitive.

The ESR spectrum of Bio-G is characterized by two main signals. The first signal at g approximately = 4.3 corresponds to Fe3+ impurities and the second signal at g approximately = 2.0130 with line-width 10.85 G is ascribed as a hole center. The gamma-ray dose response and thermal stability were studied to establish the suitability of bioglass as an ESR dosimeter. A radical formation efficiency, G-value, of 0.53 +/- 0.11 was obtained. The lifetime of radicals and the activation energy were estimated from Arrhenius plots to be approximately 255 +/- 46 days and 0.71 eV, respectively. c2003 Elsevier Ltd. All rights reserved.

AN - 67290298; 15856569 AB - This paper examines the effect of high-dose irradiation on the optically stimulated luminescence (OSL) of Al2O3:C, principally on the shape of the OSL decay curve and on the OSL sensitivity. The effect of the degree of deep trap filling on the OSL was also studied by monitoring the sensitivity changes after doses of beta irradiation and after step-annealing of samples previously irradiated with high doses. The OSL response to dose shows a linear-supralinear-saturation behavior, with a decrease in the response for doses higher than those required for saturation. This behavior correlates with the sensitivity changes observed in the samples annealed only to 773 K, which show sensitization for doses up to 20-50 Gy and desensitization for higher doses. Data from the step-annealing study leads to the suggestion that the sensitization is caused by the filling of deep electron traps, which become thermally unstable at 1100-1200 K, whereas the desensitization is caused by the filling of deep hole traps, which become thermally unstable at 800-875 K, along with a concomitant decrease in the concentration of recombination centers (F+ -centers). Changes in the shape of the OSL decay curves are also observed at high doses, the decay becoming faster as the dose increases. These changes in the OSL decay curves are discussed in terms of multiple overlapping components, each characterized by different photoionization cross-sections. However, using numerical solutions of the rate equations for a simple model consisting of a main trap and a recombination center, it is shown that the kinetics of OSL process may also be partially responsible for the changes in the OSL curves at high doses in Al2O3:C. Finally, the implication of these results for the dosimetry of heavy charged particles is discussed. c2004 Elsevier Ltd. All rights reserved.

This morphology has been proposed to constitute a biomarker (i.e., formed only in biogenic processes). A subpopulation of magnetite crystals associated with carbonate globules in Martian meteorite ALH84001 is reported to have this morphology, and the observation has been taken as evidence for biological activity on Mars. In this study, we present evidence for the exclusively inorganic origin of [111]-elongated magnetite crystals in ALH84001. We report three-dimensional (3-D) morphologies for approximately 1000 magnetite crystals extracted from: (1) thermal decomposition products of Fe-rich carbonate produced by inorganic hydrothermal precipitation in laboratory experiments: (2) carbonate globules in Martian meteorite ALH84001; and (3) cells of magnetotactic bacterial strain MV-1. The 3-D morphologies were derived by fitting 3-D shape models to two-dimensional bright-field transmission-electron microscope (TEM) images obtained at a series of viewing angles. The view down the {110} axes closest to the [111] elongation axis of magnetite crystals ([111].{110}not =0) provides a 2-D projection that uniquely discriminates among the three [111]-elongated magnetite morphologies found in these samples: [111]-elongated truncated hexaoctahedron ([111]-THO), [111]-elongated cubo-octahedron ([111]-ECO), and [111]-elongated simple octahedron ([111]-ESO). All [111]-elongated morphologies are present in the three types of sample, but in different proportions. In the ALH84001 Martian meteorite and in our inorganic laboratory products, the most common [111]-elongated magnetite crystal morphology is [111]-ECO. In contrast, the most common morphology for magnetotactic bacterial strain MV-1 is [111]-THO. These results show that: (1) the morphology of [111]-elongated magnetite crystals associated with the carbonate globules in Martian meteorite ALH84001 is replicated by an inorganic process; and (2) the most common crystal morphology for biogenic (MV-1) magnetite is distinctly different from that in both ALH84001 and our inorganic laboratory products. Therefore, [111]-elongated magnetite crystals in ALH84001 do not constitute, as previously claimed, a "robust biosignature" and, in fact, an exclusively inorganic origin for the magnetite is fully consistent with our results. Furthermore, the inorganic synthesis method, i.e., the thermal decomposition of hydrothermally precipitated Fe-rich carbonate, is a process analogue for formation of the magnetite on Mars. Namely, precipitation of carbonate globules from carbonate-rich hydrothermal solutions followed at some later time by a thermal pulse, perhaps in association with meteoritic impact or volcanic processes on the Martian surface.

The impact melt and breccias in the Yax-1 borehole are 100 m thick, which is approximately 1/5 the thickness of breccias and melts exposed in the Yucatan-6 exploration hole, which is also thought to be located between the peak ring and final rim of the Chicxulub crater. The sequence and composition of impact melts and breccias are grossly similar to those in the Yucatan-6 hole. Compared to breccias in other impact craters, the Chicxulub breccias are incredibly rich in silicate melt fragments (up to 84% versus 30 to 50%, for example, in the Ries). The melt in the Yax-1 hole was produced largely from the silicate basement lithologies that lie beneath a 3 km-thick carbonate platform in the target area. Small amounts of immiscible molten carbonate were ejected with the silicate melt, and clastic carbonate often forms the matrix of the polymict breccias. The melt unit appears to have been deposited while molten but brecciated after solidification. The melt fragments in the polymict breccias appear to have solidified in flight, before deposition, and fractured during transport and deposition.

These anomalies are believed to have originated during chemical reactions in a cold molecular cloud that was the precursor to the Solar System. The chemical and mineralogical studies reported here thus constitute direct studies of preserved molecular cloud materials. The H and N isotopic anomalies are hosted by different hydrocarbons that reside in the abundant carbonaceous matrix of the IDPs. Infrared measurements constrain the major deuterium (D) host in the D-enriched IDPs to thermally labile aliphatic hydrocarbon groups attached to macromolecular material. Much of the large variation observed in D/H in this suite of IDPs reflects the variable loss of this labile component during atmospheric entry heating. IDPs with elevated (super 15) N/ (super 14) N ratios contain N in the form of amine (-NH (sub 2) ) functional groups that are likely attached to other molecules such as aromatic hydrocarbons. The host of the N isotopic anomalies is not as readily lost during entry heating as the D-rich material. Infrared analysis shows that while the organic matter in primitive anhydrous IDPs is similar to that observed in acid residues of primitive chondritic meteorites, the measured aromatic:aliphatic ratio is markedly lower in the IDPs.

We investigate the partitioning of Li and B in martian igneous minerals experimentally, using a composition approximating that of the Queen Alexandria Range (QUE) 94201 martian basalt in one-atmosphere gas-mixing furnaces. Partition coefficients obtained for pyroxene (D (sub Li) = 0.2, D (sub B) = 0.023), plagioclase (D (sub Li) = 0.37, D (sub B) = 0.024), olivine (D (sub Li) = 0.27, D (sub B) = 0.007) and merrillite (D (sub Li) = 0.7, D (sub B) = 0.03), measured using Secondary Ion Mass Spectrometry of experimental charges, demonstrate that Li and B are incompatible in these minerals. As a test of our experimentally determined, anhydrous partition coefficients, we analyzed pyroxene in the Pasamonte eucrite, an asteroidal basalt with an anhydrous petrogenesis. Coupling of the partition coefficients with Pasamonte pyroxene analyses gives B parental melt concentrations in relative agreement with bulk rock analyses; however, Li parental melt concentrations and bulk analyses do not agree, suggestive of post-crystallization modification of Li zoning trends. Our results demonstrate that Li and B zoning patterns in pyroxene in martian basalts cannot be explained by the uptake of Li and B by co-crystallizing plagioclase, olivine, or merrillite, and suggest that the petrogeneses of Shergotty and Zagami involved something other than simple, one-atmosphere, anhydrous crystallization.

Specifically, these measurements included acetone (CH sub(3)COCH sub(3)), methylethyl ketone (CH sub(3)COC sub(2)H sub(5), MEK), methanol (CH sub(3)OH), ethanol (C sub(2)H sub(5)OH), acetaldehyde (CH sub(3)CHO), propionaldehyde (C sub(2)H sub(5)CHO), peroxyacylnitrates (PANs) (C sub(n)H sub(2n+1)COO sub(2)NO sub(2)), and organic nitrates (C sub(n)H sub(2n+1)ONO sub(2)). Complementary measurements of formaldehyde (HCHO), methyl hydroperoxide (CH sub(3)OOH), and selected tracers were also available. OVOC were abundant in the clean troposphere and were greatly enhanced in the outflow regions from Asia. Background mixing ratios were typically highest in the lower troposphere and declined toward the upper troposphere and the lowermost stratosphere. Their total abundance (o1; OVOC) was nearly twice that of nonmethane hydrocarbons (o1; C sub(2)-C sub(8) NMHC). Throughout the troposphere, the OH reactivity of OVOC is comparable to that of methane and far exceeds that of NMHC. A comparison of these data with western Pacific observations collected some 7 years earlier (February-March 1994) did not reveal significant differences. Mixing ratios of OVOC were strongly correlated with each other as well as with tracers of fossil and biomass/biofuel combustion. Analysis of the relative enhancement of selected OVOC with respect to CH sub(3)Cl and CO in 12 plumes originating from fires and sampled in the free troposphere (3-11 km) is used to assess their primary and secondary emissions from biomass combustion. The composition of these plumes also indicates a large shift of reactive nitrogen into the PAN reservoir thereby limiting ozone formation. A three-dimensional global model that uses state of the art chemistry and source information is used to compare measured and simulated mixing ratios of selected OVOC. While there is reasonable agreement in many cases, measured aldehyde concentrations are significantly larger than predicted. At their observed levels, acetaldehyde mixing ratios are shown to be an important source of HCHO (and HO sub(x)) and PAN in the troposphere. On the basis of presently known chemistry, measured mixing ratios of aldehydes and PANs are mutually incompatible. We provide rough estimates of the global sources of several OVOC and conclude that collectively these are extremely large (150-500 Tg C yr super(-1)) but remain poorly quantified.

To assess fast photochemical theory over the east Asian coast and western Pacific, these measurements are compared to predictions using a photochemical time-dependent box model constrained by coincident measurements of long-lived tracers and physical parameters. Both OH and HO sub(2) are generally overpredicted by the model throughout the troposphere, which is a different result from previous field campaigns. The calculated-to-observed ratio of OH shows an altitude trend, with OH overpredicted by 80% in the upper troposphere and by 40-60% in the middle troposphere. Boundary layer and lower tropospheric OH ratios decrease from middle tropospheric values to 1.07 for the DC-8 and to 0.70 for the P3-B. HO sub(2) measured on the DC-8 is overpredicted by a median of 23% and shows no trend in the agreement with altitude. Three subsets of data which compose 12% of the HO sub(2) measurements represent outliers with respect to calculated-to-observed ratios: stratospherically influenced air, upper tropospheric data with NO > 135 pptv, and data from within clouds. Pronounced underpredictions of both HO sub(2) and OH were found for stratospherically influenced air, which is in contrast to previous studies showing good agreement of predicted and observed HO sub( x ) in the stratosphere. Observational evidence of heterogeneous uptake of HO sub(2) within low and middle tropospheric clouds is presented, though there is no indication of significant HO sub(2) uptake within higher-altitude clouds. Model predictions of CH sub(2)O are in good agreement with observations in the median for background concentrations, but a large scatter exists. Factors contributing to this scatter are examined, including the limited availability of some important constraining measurements, particularly CH sub(3)OOH. Some high concentrations of CH sub(2)O near the coast are underpredicted by the box model as a result of the inherent neglect of transport effects of CH sub(2)O and its precursors via the steady state assumption; however, these occurrences are limited to similar to 1% of the data. For the vast majority of the atmosphere, transport is unimportant in the budget of CH sub(2)O, which may be considered to be in steady state. JF - Journal of Geophysical Research. D.

Time-average soil moisture fields from the satellite and the model largely agree in the global patterns of wet and dry regions. Moreover, the time series and anomaly time series of monthly mean satellite and model soil moisture are well correlated in the transition regions between wet and dry climates where land initialization may be important for seasonal climate prediction. However, the magnitudes of time-average soil moisture and soil moisture variability are markedly different between the datasets in many locations. Absolute soil moisture values from the satellite and the model are very different, and neither agrees better with ground data, implying that a 'correct' soil moisture climatology cannot be identified with confidence from the available global data. The discrepancies between the datasets point to a need for bias estimation and correction or rescaling before satellite soil moisture can be assimilated into land surface models.

On a regional scale, it is however not a readily measured variable and observations of its individual components are scarce. This study investigates the feasability of estimating monthly terrestrial water-storage variations from water-balance computations, using the following three variables: water vapor flux convergence, atmospheric water vapor content, and river runoff. The two first variables are available with high resolution and good accuracy in the present reanalysis datasets, and river runoff is commonly measured in most parts of the world. The applicability of this approach is tested in a 10-yr (1987-96) case study for the Mississippi River basin. Data used include European Centre for Medium- Range Weather Forecasts 40-yr reanalysis (ERA-40) data (water vapor flux and atmospheric water vapor content) and runoff observations from the United States Geological Survey. Results are presented for the whole Mississippi River basin and its subbasins, and for a smaller domain covering Illinois, where direct measurements of the main components of the terrestrial water storage (soil moisture, groundwater level, and snow cover) are available. The water-balance estimates of monthly terrestrial water-storage variations show excellent agreement with observations taken over Illinois. The mean seasonal cycle, as well as interannual variations, are captured with notable accuracy. Despite this excellent agreement, it is not straightforward to integrate the computed variations over longer time periods, because there are small systematic biases in the monthly changes. These biases likely result from inaccuracies of the atmospheric assimilation system used to estimate the atmospheric water vapor convergence and can be corrected in part with the application of a simple detrending procedure. It is noteworthy that the critical domain size for water-balance computations, using high-resolution reanalysis data such as ERA-40, appears to be much smaller than for raw radiosonde data. The Illinois domain has a size of only similar to 2 x 105 km2 and is shown to be suitable for the computation of the water-balance estimates. A comparison for other regions would be needed in order to confirm this result.

The conditional pdfs, though broad and overlapping, are indeed distinct at a high (99.9%) level of confidence. This implies a nonzero degree of predictability for midlatitude precipitation, even at 3-month leads. This behavior is reproduced by an AGCM only when land-atmosphere feedback in the model is enabled.

InSAR supplements two-dimensional remote sensing with information in the vertical dimension. Its strengths in potential for global coverage complement those of lidar (light detecting and ranging), which has the potential for high-accuracy vertical profiles over small areas. InSAR derives its sensitivity to forest vertical structure from the differences in signals received by two, spatially separate radar receivers. Estimation of parameters describing vertical structure requires multiple-polarization, multiple frequency, or multiple-baseline InSAR. Combining InSAR with complementary remote sensing techniques, such as hyperspectral optical imaging and lidar, can enhance vertical-structure estimates and consequent biophysical quantities of importance to ecologists, such as biomass. Future InSAR experiments will supplement recent airborne and spaceborne demonstrations, and together with inputs from ecologists regarding structure, they will suggest designs for future spaceborne strategies for measuring global vegetation structure.

The model, called CASA (Carnegie Ames Stanford Approach), is a process-based ecosystem depiction of plant and soil processes, including all major cycles of water and carbon. CASA's dynamic vegetation component is intended to facilitate coupling to general circulation models of the atmosphere, which require mechanistic fluxes and feedbacks from terrestrial vegetation. Simulation results for selected Alaska sites of Denali National Park suggest that the past 50-year climate trends of warming temperatures may shift the taiga ecosystem from dominance by evergreen needleleaf trees to a more mixed broadleaf-needleleaf tree composition. For other (higher elevation) areas of Denali, our model predicts that a difference of only about 3 degree C in mean annual air temperatures appears to differentiate the permanent presence of tundra vegetation forms over taiga forest. The model predicts that over the 1950-1999 climate record at Denali station, the changing taiga ecosystems were net sinks for atmospheric CO sub(2) of about 1.3 kg C m super(-2). During the warm 1990s, these forests were predicted to be net carbon sinks of more than 15 g C m super(-2) per year in 8 out of 10 years. Predicted NPP for the forest continues to increase with a projected warming trend for the next 25 years at a mean rate of about +1.2 g C m super(-2) per year. On the basis of these model results, a series of crucial field site measurements can be identified for inclusion in subsequent long-term ecological studies of the changing taiga forest.

Part I: Wet- and Dry-Season Surface Radiation Budget Flux and Precipitation Variability Based on GOES Retrievals AN - 17282179; 5988806 AB - In this first part of a two-part investigation, large-scale Geostationary Operational Environmental Satellite (GOES) analyses over the Amazonia region have been carried out for March and October of 1999 to provide detailed information on surface radiation budget (SRB) and precipitation variability. SRB fluxes and rainfall are the two foremost cloud-modulated control variables that affect land surface processes, and they require specification at space-time resolutions concomitant with the changing cloud field to represent adequately the complex coupling of energy, water, and carbon budgets. These processes ultimately determine the relative variations in carbon sequestration and carbon dioxide release within a forest ecosystem. SRB and precipitation retrieval algorithms using GOES imager measurements are used to retrieve surface downward radiation and surface rain rates at high space-time resolutions for large-scale carbon budget modeling applications in conjunction with the Large-Scale Biosphere-Atmosphere Experiment in Amazonia. To validate the retrieval algorithms, instantaneous estimates of SRB fluxes and rain rates over 8 km x 8 km areas were compared with 30-min-averaged surface measurements obtained from tower sites located near Ji-Parana and Manaus in the states of Rondonia and Amazonas, respectively. Because of large aerosol concentrations originating from biomass burning during the dry season (i.e., September and October for purposes of this analysis), an aerosol index from the Total Ozone Mapping Spectrometer is used in the solar radiation retrieval algorithm. The validation comparisons indicate that bias errors for incoming total solar, photosynthetically active radiation (PAR), and infrared flux retrievals are under 4%, 6%, and 3% of the mean values, respectively. Precision errors at the analyzed space- time scales are on the order of 20%, 20%, and 5%. The visible and infrared satellite measurements used for precipitation retrieval do not directly detect rainfall processes, and yet they are responsive to the rapidly changing cloud fields, which are directly associated with precipitation life cycles over the Amazon basin. In conducting the validation analysis at high space-time scales, the comparisons indicate systematic bias uncertainties on the order of 25%. These uncertainties are comparable to published values from an independent assessment of bias uncertainties inherent to the current highest-quality satellite retrievals, that is, from the Tropical Rainfall Measuring Mission. Because precipitation is a weak direct control on photosynthesis for the Amazon ecosystem, that is, photosynthesis is dominated by the strong diurnal controls of incoming PAR and ambient air-canopy temperatures, such uncertainties are tolerable. By the same token, precipitation is a strong control on soil thermal properties and carbon respiration through soil moisture, but the latter is a time-integrating variable and thus inhibits introduction of modeling errors caused by random errors in the precipitation forcing. The investigation concludes with analysis of the monthly, daily, and diurnal variations intrinsic to SRB and rainfall processes over the Amazon basin, including explanations of how these variations arise during wet- and dry-season periods.

One hypothesis suggests that snakes are most closely related to terrestrial lizards, and reduced their limbs on land. An alternative hypothesis proposes that snakes are most closely related to Cretaceous marine lizards, such as mosasaurs, and reduced their limbs in water. A presumed close relationship between living monitor lizards, believed to be close relatives of the extinct mosasaurs, and snakes has bolstered the marine origin hypothesis. Here, we show that DNA sequence evidence does not support a close relationship between snakes and monitor lizards, and thus supports a terrestrial origin of snakes.

In their earlier work, T. Pechmann & D. Zerbst (2002) reported evidence for grammatical category constraints in a picture-word interference task. Although grammatical category information was not activated when subjects produced bare noun descriptions of simple objects, a robust effect arose when the target word had to be embedded in a syntactic frame. The current experiments demonstrate that compilation of a simple noun phrase (NP) yields word class effects in picture-word interference experiments in the same time frame as that generally observed for semantic processing. Most significantly, the effect emerges both in German & English with very similar profiles. On these grounds, it is implausible that the effect depends on syntactic gender activation, because such constraints are lacking in the English language version of the experiments. 4 Tables, 4 Figures, 35 References.

At water supersaturated conditions, proto-phyllosilicates formed by spinodal-type homogeneous nucleation. Their formation and subsequent growth was entirely determined by the availability of water via pore spaces inherited from the original smokes and the textural continuity of magnesiosilica material with a mostly smectite-dehydroxylate composition. The results may have implications for the hydration of proto-CI material, the presence of rare periclase and brucite in primitive solar system bodies, and the pervasiveness of hydrated amorphous magnesiosilica dust and saponite proto-phyllosilicates in icy-protoplanets, such as comet nuclei.

The Eel River Basin (ERB), located on the continental slope off Northern California, contains active methane vents and seep-associated chemosynthetic biological communities (CBC) on the crests of anticlines in approximately 520-m water depth. Seep-related features on the seafloor have a patchy distribution and include active bubbling vents, chemosynthetic clam beds, and sulfide-oxidizing bacterial mats. Methane sources supplying local seeps are heterogeneous on all spatial scales and support a large and diverse microbial assemblage involved in the anaerobic oxidation of methane (AOM). To develop a comprehensive understanding of the complex biological, geochemical and physical processes associated with, and influencing seafloor methane seepage, a multidisciplinary approach is required. Here we present an integrative, multidisciplinary study that illustrates the diverse processes associated with seafloor methane seepage within the Eel River Basin and the complex interactions defining the geochemistry, mineralogy and microbiology within this environment.

Only a very small percentage of the combinations match the oxygen isotopic composition, the assumed bulk FeO concentration, and the assumed Fe/Al weight ratio for the Earth. Since chondrites are enriched in silicon relative to estimates of the bulk Earth, none of the combinations fall near the terrestrial magmatic fractionation trend line in Mg/Si-Al/Si space. More combinations match the oxygen isotopic composition and the assumed bulk FeO concentration for Mars. These combinations fall near the trend for shergottite meteorites in Mg/Si-Al/Si space. One explanation for the difficulty in forming Earth out of known chondrites is that the Earth may be composed predominately of material that did not survive to the present day as meteorites. Another explanation could be that significant amounts of silicon are sequestered in the core and/or lower mantle of the Earth.

This sampling consisted of in situ vertical profiles of CO by NASA's DC-8 aircraft intended to provide data useful for validating MOPITT observations of CO column. One particular profile conducted over the central North Pacific revealed a layer of pollution characterized by CO mixing ratios more than double background values. Sampling of the surrounding region by both the NASA DC-8 and P-3B aircraft showed this layer to have a considerable geographic extent, at least 25 degree longitude ( similar to 2500 km) and 4 degree latitude ( similar to 400 km). Using back trajectory analysis, this polluted layer is followed back in time and compared with four consecutive MOPITT overpasses. MOPITT observations during these four overpasses agree well with the location of the layer as inferred by the trajectories; however, the detected CO column amount increases backward in time by just over 20%. Further analysis shows that the majority of this change in detected column abundance is consistent with two factors: (1) changes in the thickness of the polluted layer over time (9 plus or minus 3%) and (2) changes in retrieved column abundance due to the altitude of the layer (7 plus or minus 3%). This demonstrates that there are both real and artificial sources of variability that must be understood before MOPITT observations can be quantitatively useful. An unexpected finding was the difference in the variance of MOPITT observations depending on whether observations were taken under daylight or nighttime conditions. The variance in daytime observations of the polluted layer was approximately double that for nighttime data. The results of this analysis indicate that targeted in situ sampling of large-scale pollution events can provide insight leading to more realistic interpretation of MOPITT observations. Strategies for sampling such events repeatedly during their evolution could also provide more interesting opportunities for validation. JF - Journal of Geophysical Research. D.

This model is driven by observed surface climate and monthly estimates of vegetation leaf area index (LAI) and fraction of absorbed PAR (fraction of photosynthetically active radiation, FPAR) generated from the NOAA satellite advanced very high-resolution radiometer (AVHRR) and similar sensors. Land surface AVHRR data processing using modified moderate-resolution imaging spectroradiometer radiative transfer algorithms includes improved calibration for intra- and intersensor variations, partial atmospheric correction for gaseous absorption and scattering, and correction for stratospheric aerosol effects associated with volcanic eruptions. Results from our analysis suggest that anomalies of net primary production and net ecosystem production predicted from the NASA-CASA model over large areas of the Amazon region east of 60 degree W longitude are strongly correlated with the Southern Oscillation index. Extensive areas of the south-central Amazon show strong linkages of the FPAR and the NASA-CASA anomaly record to the Arctic Oscillation index, which help confirm a strong relation to southern Atlantic climate anomalies, with associated impacts on Amazon rainfall patterns. Processes are investigated for these teleconnections of global climate to Amazon ecosystem carbon fluxes and regional land surface climate.

BC was 5-72% of UDOM-C (27 plus or minus 17%), which corresponds to 8.9 plus or minus 6.5% of dissolved organic carbon (DOC), with higher values in the heavily urbanized midbay region of the Delaware Estuary and lower yields in the river and coastal ocean. The spatial and seasonal distributions of BC along the salinity gradient of Delaware Bay suggest that the elevated levels of BC in surface water UDOM originate from localized sources, possibly from atmospheric deposition or release from resuspended sediments. BC in UDOM made up 4-7% of the DOC in the coastal Atlantic Ocean, revealing that river-estuary systems are important exporters of colloidal BC to the ocean. The annual flux of BC from Delaware Bay UDOM to the Atlantic Ocean was estimated at 2.4 x 10 super(10) g BC yr super(-1), supporting the hypothesis that the DOC pool is an important contributor of BC to the ocean.

Analysis is based on satellite, radar, sounding, and profiler observations of precipitating systems and cloudiness from the Tropical Rainfall Measuring Mission Large-Scale Biosphere-Atmosphere (TRMM-LBA) and the coincident Wet-Season Atmospheric Mesoscale Campaign (WETAMC) field programs during the early 1999 wet season. The general finding is that following the collapse of the nearly ubiquitous and locally generated afternoon ('noon balloon') convection, organized deep convection contributes to a postmidnight maximum in raining area and high cloudiness, and to a lesser extent rainfall. Nocturnal convective systems have the effect of weakening and delaying the onset of the following afternoon's convection. Many of these nocturnal convective events are traced to large- scale squall lines, which propagate westward thousands of kilometers from their point of origin along the northeast coast of Brazil. In addition, a previously undescribed nocturnal stratiform drizzle phenomenon, generated above the melting layer independently from deep convection, contributes significantly to nocturnal cloud cover. Results from this study underscore the complex influence of propagating large-scale organized convection in locally modulating the diurnal variation in clouds and rain. The greatest significance of the nocturnal drizzle may be the potential effect on the diurnal radiation budget by the extensive midlevel nocturnal clouds rather than their marginal contribution to nocturnal rainfall.

The purpose of this project was to compare foot-ground reaction force during iRED exercise in normal gravity (1 G) vs. microgravity (0 G) achieved during parabolic flight. Methods: There were four subjects who performed three exercises (squat, heel raise, and deadlift) using the iRED during 1 G and 0 G at a moderate intensity (60% of maximum strength during deadlift exercise). Foot-ground reaction force was measured in the three orthogonal axes (x, y, z) using a force plate, and the magnitude of the resultant force vector was calculated (r = square root x super(2) + y super(2) + z super(2)). Linear displacement (LD) was measured using a linear transducer. Peak force (F sub(peak)) and an index of total work (TWi) were calculated using a customized computer program. Paired t-tests were used to test if significant differences (p less than or equal to 0.05) were observed between 1 G and 0 G exercise. Results: F sub(peak) and TWi measured in the resultant axis were significantly less in 0 G for each of the exercises tested. During 0 G, F sub(peak) was 42-46% and TWi was 33-37% of that measured during 1 G. LD and average time to complete each repetition were not different from 1 G to 0 G. Conclusions: Crewmembers who perform resistive exercises during spaceflight that include the movement of a large portion of their body mass will require much greater external resistive force during 0 G than 1 G exercise to provide a sufficient stimulus to maintain muscle and bone mass.

The magnitude of this gradient would conventionally be interpreted as indicating low export of organic matter from ocean surface waters, but steady-state simulations using a two-box model of the Paleoproterozoic ocean suggest that the small carbon isotope gradient could instead be due to high partial pressures of carbon dioxide in the Paleoproterozoic atmosphere, which would increase the oceans dissolved inorganic carbon content and damp the effects of biological pumping. If the Paleoproterozoic atmosphere were indeed enriched in atmospheric CO sub(2) in compensation for a less luminous Sun, these results indicate that the planktonic biota was a significant component of the Precambrian global carbon and nutrient cycles, affecting if not regulating (as today) the composition of both surface and deep ocean waters.

The approach identifies possible cloud pixels through the use of the normalized difference snow index (NDSI). Possible cloud pixels are grown into regions and edges are determined. Possible cloud edges are then matched with possible cloud shadow regions using knowledge of the solar illumination azimuth. A scoring index quantifies the quality of each match resulting in a classified image. The best value of the NDSI threshold is shown to vary significantly, forcing the algorithm to be iterated through many threshold values. Computational efficiency is achieved by using sub-sampled images with only minor degradation in cloud-detection performance. The algorithm detects all clouds in each of eight test Landsat-7 images and makes no incorrect cloud classifications.

AN - 36434378; 10734 AB - PURPOSE: The implementation of the Mars Exploration Program (MEP) is proposed. The MEP would constitute a science-driven, technology-enabled effort to characterize and understand Mars suing an exploration strategy that would focus on evidence of the presence of water on the planet. Following the pathways and cycles of water may lead to preserved ancient records of biological processes as well as to a characterization of the environments on Mars. The proposed action would involve the preparation and implementation of a coordinated series of robotic orbital, surface, and atmospheric missions to gather scientific data on Mars and its environments through 2020. Continued planning for sample return missions, which would enable study of Martian samples in Earth-based laboratories, would be included. Some MEP missions could sue radioisotope power systems for electricity, radioisotope heating units for thermal control, and small quantities of radioisotopes in science instruments for experiments and instrument calibration. This programmatic EIS presents an overview of the currently proposed MEP missions, available launch vehicles, the affected environment, and the potential environmental consequences associated with the proposed action, an alternative proposal, and a No Action Alternative. Environmental impacts associated with specific missions would be addressed in subsequent environmental documentation as required. Each mission in the long-term series would contribute incrementally to the overall program objectives, gathering data that would build upon knowledge and insights gained from prior missions. Thus, the Mars Global Surveyor (MGS) and Mars Oddyssey continue the global reconnaissance of the planet with studies of the Martian atmosphere, interior, magnetic field, and chemical and physical characteristics of the surface. The Mars Exploration Rover missions, launched in 2003, would intensively study diverse local areas of the planet's surface and provide data that are essential for placing the global data in a more meaningful context. Future missions encompassed by the proposed action would continue the systematic exploration of Mars begun by NASA with MGS in 1996, building upon scientific data already returned and expected to be returned. The proposed action (Alternative 1) would send at least one spacecraft to Mars during each launch opportunity, extending through the first two decades of this century. Efficient launch opportunities occur every 26 months. MEP missions would be launched via expendable vehicles from either Cape Canaveral Air Force Station, Florida or Vandenberg Air Force Base, California. Near-term missions would occur in 2005, 2007, 2009, and 2011. Alternative 2 would continue to explore Mars through 2020, but on a less frequent, less comprehensive, mission-by-mission basis. These missions could include international partners. POSITIVE IMPACTS: The MEP would allow U.S. scientists to determine whether life exists or has ever existed on Mars; understand the current state and evolution of the Martian atmosphere, surface, and interior; an develop an understanding of mars in support of possible future human exploration. NEGATIVE IMPACTS: Rocket launches would result in short-term emissions of air pollutants, affecting only local air quality. Two types of nonradiological accidents could have consequences beyond the immediate vicinity of the launch site: a large liquid propellant spill during fueling operations and a launch failure. Either of these types of accidents would imperil only workers. The potential short term effects of an accident would include a localized fireball, falling fragments from the explosion of the vehicle, release of unburned propellants and propellant combustion products, and death or damage to nearby biota and brush fires near the launch pad. For accidents involving solid rocket motors, large pieces of unburned solid propellant would fall to the ground and could enter the ocean or nearby surface water bodies. The use of radioisotopes would engender the risk of release of radioactive materials into the atmosphere and the aquatic environment in the event of an accident.

AN - 80158869; 14968783 AB - Bacteriorhodopsin (bR) is an attractive intelligent material. Understanding the mechanism of its light-driven proton pumping outward the cell implicates it in many technical applications, particularly, in what is called optical computers, and the biotechnology is waiting for this promised biological molecule. An ionizing radiation source handling could be computerized in radiation fields. The computer containing such biological material will not be out of reach of the fields of ionizing radiation. So it is interesting to report on the working of such biological computer if it is subjected to ionizing radiation. The functional unit in this molecule is retinal chromophore. In the present work, it is interested to assess the functionality of bR through determining the electronic transition dipole moment of its chromophore. Significant changes in the values of the absorption transition dipole moment were noticed at different doses of beta-particles in the range of 0.1-0.3 kGy. Ionizing radiation-induced changes in bR were followed by intrinsic fluorescence spectroscopy. An analysis of the fluorescence data bears on the tertiary structure of bR. The emission spectrum is, however, red shifted with an increase in intensity with the different doses; in the meanwhile, gradual decrease in the visible absorbance has occurred till almost complete loss is attained. This bleaching due to ionizing radiation may offer an alternative way of data processing in such optical devices based on bR. Nevertheless, bR has proofed to be used as a biological indicator of ionizing radiation. However, the potential of bR for use as a biosensor to detect ionizing radiation should be considered. c2003 Elsevier Ltd. All rights reserved.

AN - 80110059; 14740657 AB - The aim of this paper is to review the main results of medical support of 78 two-person extravehicular activities (EVAs) which have been conducted in the Mir Space Program. Thirty-six male crewmembers participated in these EVAs. Maximum length of a space walk was equal to 7 h 14 min. The total duration of all space walks reached 717.1 man-hours. The maximum frequency of EVA's execution was 10 per year. Most of the EVAs (67) have been performed at mission elapsed time ranging from 31 to 180 days. The oxygen atmosphere of the Orlan space suit with a pressure of 40 kPa in combination with the normobaric cabin environment and a short (30 min) oxygen prebreathe protocol have minimized the risk of decompression sickness (DCS). There has been no incidence of DCS during performed EVAs. At the peak activity, metabolic rates and heart rates increased up to 9.9-13 kcal/min and 150-174 min-1, respectively. The medical problems have centred on feeling of moderate overcooling during a rest period in a shadow after the high physical loads, episodes with tachycardia accompanied by cardiac rhythm disorders at the moments of emotional stress, pains in the muscles and general fatigue after the end of a hard EVA. All of the EVAs have been completed safely. c2003 Elsevier Ltd. All rights reserved.

Long-term potentiation (LTP) of hippocampus induced potential and lipofuscin content in rat brain were studied. After irradiated by a 2450 MHz microwave, rats hippocampus induced potential in vivo was recorded and lipofuscin content in the brain was measured by fluorospectrophotometry. Continuous microwave with 10-25 mW/cm2 intensity could inhibit the amplitude of the population spike (PS) of weak and strong stimuli induced LTP with an intensity-effect relationship. At 25 mW/cm2, lipofuscin content was significantly higher than control and 10 mW/cm2 group (P<0.05). Continuous microwave with 10-25 mW/cm2 intensity impairs learning and memory by restraining hippocampus LTP and brain lipofuscin content.

The animals were killed sequentially at 3, 6, 12, 24, 48 and 72 h. Nitrogen tetroxide was administrated through inhalation at the concentration of 81 mg/m3 for 15 min. Chronic injuries and pathologic changes were also observed one year after the intoxication. Pulmonary edema was the main pathological changes after intoxication, complicated with partial haemorrhage. Data acquired from long-term observations showed 75% pulmonary fibrosis and one case of adenocarcinoma of lung. The first 2 to 6 h after intoxication is the most severe stage of the injury. During the long-term observation, we find that intoxication with nitrogen tetroxide can induce pulmonary fibrosis and adenocarcinoma.

TOPEX/Poseidon altimeter data show that subpolar sea surface height increased during the 1990s, and the geostrophic velocity derived from altimeter data exhibits declining subpolar gyre circulation. Combining the data from earlier satellites, we find that subpolar circulation may have been weaker in the late 1990s than in the late 1970s and 1980s. Direct current-meter observations in the boundary current of the Labrador Sea support the weakening circulation trend of the 1990s and, together with hydrographic data, show that the mid- to late 1990s decline extends deep in the water column. Analysis of the local surface forcing suggests that the 1990s buoyancy forcing has a dynamic effect consistent with altimetric and hydrographic observations: A weak thermohaline forcing allows the decay of the domed structure of subpolar isopycnals and weakening of circulation.

Formulae to calculate the probability of detecting compound chondrules in thin sections are derived and applied to previous studies. This reinterpretation suggests that at least 5% of chondrules are compounds, a value that agrees well with studies in which whole chondrules were removed from meteorites. The observation that adhering compounds tend to have small contact arcs is strengthened by application of these formulae. While it has been observed that the secondaries of compound chondrules are usually smaller than their primaries, these same formulae suggest that this could be an observation bias. It is more likely than not that thin section analyses will identify compounds with secondaries that are smaller than their primaries. A new model for chondrule collisional evolution is also developed. From this model, it is inferred that chondrules would have formed, on average, in areas of the solar nebula that had solids concentrated at least 45 times over the canonical solar value.

These two groups of minerals are spectrally distinct, which relates largely to differences in the types of major cations present. Both exhibit a number of absorption features in the 0.3-26 mu m region that show systematic variations with composition and can be used to quantify or constrain certain compositional parameters, such as cation abundances, and site occupancies. For spinels, the best correlations exist between Fe (super 2+) content and wavelength positions of the 0.46, 0.93, 2.8, Restrahelen, 12.3, 16.2, and 17.5 mu m absorption features, Al and Fe (super 3+) content with the wavelength position of the 0.93 mu m absorption feature, and Cr content from the depth of the absorption band near 0.55 mu m. For chromites, the best correlations exist between Cr content and wavelength positions of the 0.49, 0.59, 2, 17.5, and 23 mu m absorption features, Fe (super 2+) and Mg contents with the wavelength position of the 1.3 mu m absorption feature, and Al content with the wavelength position of the 2 mu m absorption feature. At shorter wavelengths, spinels and chromites are most readily distinguished by the wavelength position of the absorption-band in the 2 mu m region (2.1 mu m for chromite), while at longer wavelengths, spectral differences are more pronounced. The importance of being able to derive compositional information for spinels and chromites from spectral analysis stems from the relationship between composition and petrogenetic conditions (pressure, temperature, oxygen fugacity) and the widespread presence of spinels and chromites in the inner solar system. When coupled with the ability to derive compositional information for mafic silicates from spectral analysis, this opens up the possibility of deriving petrogenetic information for remote spinel- and chromite-bearing targets from analysis of their reflectance spectra.

The experiments have been run under both dry and hydrous conditions. The shergottite was doped with 0.1, 0.5, and 1.0 wt.% Eu, Gd, and Sm oxides in different experiments and was equilibrated at liquidus conditions for 24 hours. D(Eu/Gd) (sub pigeonite/melt) in dry melts ranges from 0.156+ or -0.014 (f (sub O2) = IW -1) to 0.630+ or -0.102 (IW +3.5). D(Eu/Sm) (sub pigeonite/melt) in dry melts ranges from 0.279+ or -0.021 (IW -1) to 1.114+ or -0.072 (IW +3.5). Due to difficulties with low-f (sub O2) experiments, hydrous distribution coefficients were measured, but were not used in the calibration of the Eu-oxybarometers. These two Eu-oxybarometers provide an accurate way to measure f (sub O2) recorded during pigeonite crystallization, thereby yielding a record of f (sub O2) during the earliest period of Martian meteorite parent magma crystallization history. Using this new calibration, Martian meteorite pigeonite cores record f (sub O2) values of IW -0.6 (+ or -0.3) (QUE94201) to IW +1.9 (+ or -0.6) (Shergotty). These new values differ in magnitude, but not trend, from previously published data. The pigeonite Eu-oxybarometer yields an f (sub O2) range in the basaltic shergottites of 2 to 3 orders of magnitude. Several processes have been proposed to explain the origin of this f (sub O2) range, the majority of which rely on assimilation of an oxidized source. A potential correlation between this new pigeonite data and recent Fe-Ti oxide data, however, is consistent with intrinsic f (sub O2) differences in the magma source region being responsible for the measured f (sub O2) variations. This implies that the Martian meteorite source region, the mantle or lithosphere, may be heterogeneous in nature. However, the process of assimilation cannot be completely ruled out in that an assimilation event that took place before crystallization commenced would result in the overprinting of the source region f (sub O2) signature.

The concretions cover an area at least as large as that of Oklahoma. The outcropping rocks are apparently composed of < or = 4% of evaporite minerals including sulphates and carbonates. The hematite probably formed at approximately 100 (super o) C from goethite, and may have existed on the Martian surface for milllions of years.

Terrestrial examples of this morphology exist on the eastern Snake River plain (ESRP), Idaho, host to many late Pliocene to Holocene tholeiitic basalt shields built up over short monogenetic eruptive periods. These shields generally have low distal slopes (1-2 degrees ), but some shields, such as Table Legs Butte and Quaking Aspen Butte, have gentle (4-6 degrees ) medial slopes that sharply transition to steep proximal slopes (20 degrees -30 degrees ), forming a summit cap. We evaluate the effects of lithology and geochemistry on volcanological controls, such as change in eruptive style (i.e. from fissure to single vent) or eruptive rate that are responsible for this shield morphology. Table Legs Butte lava flows exhibit well-developed coarse diktytaxitic texture, and Quaking Aspen Butte flows exhibit a less-developed coarse diktytaxitic texture; shields without summit caps are generally non-diktytaxitic. GIS/GPS topographic profiling indicates a positive correlation between diktytaxitic coarsening and summit steepness. The diktytaxitic texture implies high volatile content, possibly related to fractionated pockets of source magma enriched in H (sub 2) O and/or CO (sub 2) . Basalts from Table Legs Butte contain over 25% skeletal plagioclase laths (up to 2cm); only 5% skeletal plagioclase laths (<1cm) are present in Quaking Aspen Butte lava flows. Both shields are low (<8%) in olivine (<1.5cm), which form glomerocrysts and cumulophyric textures with plagioclase. Zoned plagioclase (<2%) at both localities shows resorbed cores, and the groundmasses contain a dendritic network of Fe-Ti oxides (primarily skeletal ilmenite) and augite. Significant differences between the summit and flank textures on either shield are not observed. Trace element analyses further show that flank and summit regions cannot be geochemically separated. These results suggest that shield morphology is controlled by properties intrinsic to magma composition. Continued analysis of distal flows and possible analysis of melt inclusions for volatiles will lead to a better understanding of magma genesis and volcanic processes of small shields on the ESRP and Mars.

Hence accurate snow representation in coupled land-ocean-atmosphere global climate models has the potential to greatly increase prediction accuracy. To this end, a one-dimensional extended Kalman filter analysis scheme has been developed to assimilate observed snow water equivalent into the NASA Seasonal-to-Interannual Prediction Project (NSIPP) catchment-based land surface model. This study presents the results from a set of data assimilation 'twin' experiments using an uncoupled version of the land surface model. First, 'true' snow states are generated by spinning-up the land surface model for 1987 using an observation- constrained version of the European Centre for Medium-Range Weather Forecasts (ECMWF) 15-year Re-Analysis (ERA-15) data set for atmospheric forcing. A degraded 1987 simulation was then made by initializing the model with no snow on 1 January 1987. A third simulation assimilated the synthetically generated snow water equivalent 'observations' from the true simulation into the degraded simulation once a day. This study illustrates that by assimilating snow water equivalent observations, which are readily available from remote sensing satellites, other state variables (i.e. snow depth and temperature) can be retrieved and effects of poor initial conditions removed. Runoff and atmospheric flux predictions are also improved. JF - Journal of Geophysical Research. D.
