TY - JOUR T1 - Partitioning of siderophile elements in the Fe-Ni-S system; 1 bar to 80 kbar AN - 50537887; 1991-051640 AB - Partition coefficients for Au, Ni, P and Ge between solid Fe-Ni metal and sulphur-bearing metallic liquids have been measured at 7, 27 and 80 kbar. They are believed to be the only such data for Au, P and Fe at high P. Comparison of these partitioning results with those obtained at 1 bar indicate that only the 80 kbar Ge data differ significantly from the 1 bar experiments. It seems that many low P partitioning experiments in the Fe-Ni-S-P system may be applied to the greater part of the Earth's upper mantle or, alternatively, to the entire mantle of Mars.

AN - 85226985; pmid-1891303 AB - Two experiments are reported that examine the preferred increase in intensity for creating a percept of half auditory distance from a reference. The results of both experiments indicate that the use of an inverse square law (increments of 6 dB) is not the best signal-processing method for this purpose. The application of the results is potentially useful towards the software design of 3-D auditory display systems that manipulate the perceived distance of auditory inputs in relationships to actual distances of physical objects.

Information Summaries. AN - 62897708; ED345949 AB - The United States has explored the solar system with automated spacecraft and human-crewed expeditions that have produced a quantum leap in our knowledge and understanding of the solar system. Through the electronic sight and other "senses" of our automated spacecraft, color and complexion have been given to worlds that for centuries appeared to eyes on Earth as fuzzy disks or indistinct points of light and dozens of previously unknown objects have been discovered. Following a categorical listing of 41 NASA unmanned spacecraft launched between 1959 to 1990, this NASA publication contains numerous photographs and presents factual summaries of the following: (1) the evolution of automated spacecraft; (2) current knowledge about the Sun including information on spacecraft that visited the Sun and future solar missions; (3) conditions on Mercury, especially information that was learned from the Mariner 10 spacecraft; (4) information on Venus as gleaned from Mariner 2, Mariner 5, the Pioneer Venus Orbiter, the Pioneer Venus Multiprobe, and Magellan spacecraft; (5) information about the Earth as learned from trips into space; (6) information about the moon, the Apollo program, and theories on the origin of the moon; (7) detailed information on Mars including information from spacecraft on its topography, prospects for harboring extraterrestrial life, and its two moons Phobos and Deimos; (8) research on asteroids and the results of meteoroid collisions with the earth; (9) data gathered on Jupiter and its moons Io, Europa, Ganymede and Callisto; (10) data on Saturn and its rings; (11) information on Uranus, its numerous icy moons including Miranda, Ariel, Umbriel, and Titania; (12) information on Neptune and its moons including Proteus and Nereid; (13) data concerning Pluto our most distant planet and its one moon Charon; and (14) information on the composition and orbits of comets including Halley's comet. A pictorial summary chart gives further information on the planets including mean distance from the sun, relative size, periods of revolution and rotation, inclination, eccentricity, and composition of their atmospheres.

The total abundance of these phases is estimated to be < 0.01 wt.% of the bulk meteorite. The rust appears to be pre- terrestrial in origin. Ca-carbonate and Ca-sulphate are intergrown with the rust, and are thus inferred to be pre-terrestrial. Similar textural evidence for the origin of NaCl and Mg-sulphate is lacking and terrestrial contamination cannot be excluded. The rust, Ca-carbonate and Ca-sulphate were formed by precipitation from water-based solutions on the Nakhla parent planet. Aqueous alteration on the parent body may have been responsible for the disturbance of the Rb-Sr geochronometer in Nakhla at 1300 m.y.

A general model invoking unerupted magma, basaltic intrusion, and distillation can explain these high S emissions. If SO (sub 2) emission rate measurements do indeed detect mafic intrusions under volcanoes they offer a new tool for volcanologists. Research directed at clarifying and testing this new hypothesis is needed and could lead to a more realistic estimate of volcanic gas fluxes to the atmosphere and a better insight into the subsurface processes of magma bodies.

AN - 50173936; 1991-047753 AB - Ocean surface water [CO (sub 2) (aq)] variations based on glacial/interglacial changes in sediment delta (super 13) C (sub org) are shown to compare favorably with reconstructions based on ice core [CO (sub 2) ]. In particular, an approximate 80 uatm increase in atmospheric pCO (sub 2) during the last glacial-interglacial transition is calculated to correspond to a 3-4 umolar increase in ocean surface water [CO (sub 2) (aq)] at atmospheric equilibrium. A widespread marine delta (super 13) C (sub org) decrease of 1-2 per mil accompanied this event and was not preceded by an equivalent isotopic change in surface water total dissolved inorganic carbon. These observations support the hypothesis that [CO (sub 2) (aq)] influences photosynthetic isotope fractionation between marine inorganic and organic carbon pools, and therefore that plankton/sediment delta (super 13) C (sub org) may serve as a proxy for surface water [CO (sub 2) (aq)].

AN - 85176667; pmid-1708955 AB - Cupric ion-ferricyanide labeling methods and related ferrocyanide-stained tissues were used to locate and characterize, at the ultrastructural level, presumptive impulse initiation zones in the three types of vestibular macular nerve fibers. Large-diameter, M-type vestibular nerve fibers terminate in a calyx at the heminode, and labeling is coextensive with the base of the calyx. Intermediate, M/U-type nerve fibers have short, unmyelinated preterminal segments that sometimes bifurcate intramacularly, and small-diameter, U-type nerve fibers have long, unmyelinated preterminal axons and up to three branches. Preterminals of these nerve fibers display ultrastructural heterogeneity that is correlated with labeling patterns for sodium channels and/or associated polyanionic sites. They have a nodelike ultrastructure and label heavily from near the heminode to the base of the macula. Their intramacular branches, less organized ultrastructurally, label only slightly. Results indicate that vestibular nerve fibers have one impulse initiation zone, located near the heminode, that varies in length according to nerve fiber type. Structural heterogeneity may favor impulse conduction in the central direction, and length of the impulse initiation zone could influence nerve discharge patterns.

AN - 62898080; ED345947 AB - Utilizing simple and inexpensive equipment, elementary and middle school science teachers can conduct interesting, exciting, and productive units on rockets, the oldest form of self-contained vehicles in existence. This teaching guide contains the following: (1) a brief history of experimentation and research on rockets and rocket propulsion from ancient Chinese warfare to modern space exploration; (2) the mechanical principles of rockets in terms of Newton's Laws of Motion; (3) a discussion of the science of practical rocketry in terms of rocket engine design, types of propellants, engine thrust control, flight path stability and control, and weight versus payload considerations; (4) 10 hands-on classroom activities which include required materials and tools, procedures, and typical classroom discussion topics relating to each activity; and (5) a list of commercial suppliers for model rocketry resources. The activities are effective for teaching the science of rocketry, utilizing readily available materials such as soda cans, pencils, balloons, and straws. Further, these activities are suggested as an introduction to a follow-up activity of building and launching commercially-supplied model rockets. (PR) AU - Vogt, Gregory L.

Recent ground-based observations, however, have increased our understanding of the atmosphere and our fascination with it. In the lunar atmosphere we can study important physical phenomena that also exist elsewhere in the solar system where they are not so easily examined. These phenomena also cannot be duplicated in terrestrial laboratories.

AN - 80528994; 2020735 AB - Using the coupled neutron-proton space radiation transport computer code (BRYNTRN), estimates of human exposure in interplanetary space, behind various thicknesses of aluminum shielding, are made for the large solar proton events of August 1972 and October 1989. A comparison of risk assessment in terms of total absorbed dose for each event is made for the skin, ocular lens, and bone marrow. Overall, the doses associated with the August 1972 event were higher than those with the October 1989 event and appear to be more limiting when compared with current guidelines for dose limits for missions in low Earth orbit and more hazardous with regard to potential acute effects on these organs. Both events could be life-threatening if adequate shielding is not provided.

Variations of ice velocity are spatially related to surface undulations, and transverse velocity variations of up to 30 per cent occur. Such large variations negate the concept of plug flow and call into question earlier mass-balance calculations for this and other ice streams where sparse velocity data were used. The coregistration of images with the use of the topographic undulations of the ice stream, and the measurement of feature displacement with cross-correlation of image windows, provide significant improvements in the use of satellite imagery for ice-flow determination.

The volcanology investigation will include long- and short-term monitoring of selected volcanoes, the detection of precursory activity associated with unanticipated eruptions, and the detailed study of on-going eruptions. The data collected will allow us to address two aspects of volcanism: volcanic landforms and the atmospheric effects of eruptions. A variety of instruments on the two NASA EOS platforms, together with supplemental data from the Japanese and European platforms, will enable the study of local- to regional-scale thermal and deformational features of volcanoes, and the chemical and structural features of volcanic eruption plumes and aerosols. This investigation fits well within the overall goal of the EOS Project, which is to study the regional and global interrelationships between components of the Earth System, because it specifically investigates the links between volcanism, atmospheric chemistry and short-term (1-3 year) climate change.

Rough topography on the ice covering the lake surface traps sand that is transported by the wind. In late summer, vertical conduits form by melting and fracturing, making the ice permeable to both liquid water and gases. Cross-sections of the ice cover show that sand is able to penetrate into and apparently through it by descending through these conduits. This is the primary sedimentation mechanism in the lake. Sediment traps retrieved from the lake bottom indicate the rates of deposition can vary by large amounts over lateral scales as small as 1 m. In some locations on the lake bottom, distinctive sand mounds have been formed by this process. They are primary sedimentary structures and appear unique to the perennially ice-covered lacustrine environment. Rapid colonization and stabilization of fresh sand surfaces by microbial mats composed of cyanobacteria, eukaryotic algae, and heterotrophic bacteria produces a complex intercalation of organic and sandy layers that are a distinctive form of modern stromatolites.

The increases used were sufficient to melt all sea ice at high latitudes, and amounted to 15% on the global average. The resulting global climate is 2 degrees C warmer, with temperature increases of some 20 degrees C at high latitudes, and 1 degrees C near the equator. The warming is driven by the decreased sea ice/planetary albedo, a feedback which would appear to be instrumental for producing extreme high-latitude amplification of temperature changes. Resulting hydrologic and wind stress changes suggest that qualitatively, for both the wind-driven and thermohaline circulation, the increased transports might be self-sustaining. As such, they would represent a possible mechanism to help account for the high-latitude warmth of climates in the Mesozoic and Tertiary, and decadal-scale climate fluctuations during the Holocene, as well as a powerful feedback to amplify other climate forcings. It is estimated that ocean transport increases of 50-70% would have been necessary to reproduce the warmth of various Mesozoic (65-230 m.y. ago) climates without changes in atmospheric composition, while the 15% increase used in these experiments would have been sufficient to reproduce the general climatic conditions of the Eocene (40-55 Ma). A companion experiment indicates that increased topography during the Cenozoic (0-65 Ma) might have altered the surface wind stress in a manner that led to reduced heat transports; this effect would then need to be considered in understanding the beginning of ice ages. Colder climates, or rapid climate perturbations, might have been generated with the aid of such altered ocean transports. The large high-latitude amplification associated with ocean heat transport and sea ice changes differs significantly from that forecast for increased trace gases, for which water vapor increase is the primary feedback mechanism. The different signatures might allow for discrimination of these different forcings; e.g., the warming of the 1930s looks more like the altered ocean heat transport signal, while the warming of the 1980s is more like the trace gas effect. The actual change of ocean heat transport and deep water circulation both in the past and in the future represents a great uncertainty. Copyright 1991 by the American Geophysical Union.

A host of geophysical processes contribute to these variations. The present paper studies quantitatively a prime contributor, atmospheric mass redistribution, using global surface pressure data from the European Centre for Medium Range Weather Forecasts for the period of 1980-1988. Seasonal variations are focused upon: We compute the annual and semiannual amplitudes and phases of the zonal J (sub l) coefficient with degree l = 2-6 with and without the oceanic inverted-barometer (IB) effect and obtain the predicted effects on the orbit nodal residuals delta Omega of Lageos and Starlette. These predicted delta Omega are then compared with the observed delta Omega . It is found that the atmospheric influence, combined with the hydrological influence (from Chao and O'Connor, 1988), agree well with the Lageos observation for the annual term. The corresponding match appears poorer for Starlette. The comparisons for the semiannual term, however, show little agreement. The discrepancies can be attributed primarily to the uncertainty arising from the IB assumption, the systematic errors in the hydrological estimates and in the observations, as well as other geophysical processes that influence global mass distribution, particularly those in the oceans. Interannual and decadal variations, with their impact on the observations of "secular" changes are also discussed.

Both the matter component Psi (matter) and the motion component Psi (motion) are computed, the former with and without the oceanic inverted barometer (IB) effect. It is found that Psi (motion) contributes significantly to the total excitation Psi overall and nonnegligibly to the annual signal in Psi , or the annual wobble excitation, in particular. Our results for the annual wobble excitation, in terms of the prograde component Psi (super +) and the retrograde component Psi (super -) for January 1, are Psi (super +) = (16.8 milliarc seconds (mas), -93 degrees ) and Psi (super -) = (15.6 mas, -98 degrees ) with IB, and Psi (super +) = (17.3 mas, -101 degrees ) and Psi (super -) = (28.1 mas, -112 degrees ) without IB. These results are within the (rather large) range of previous estimates. The IB effect has a small impact on Psi (super +) , whereas its impact on Psi (super -) is considerable. The (better determined) prograde components Psi (super +) are then compared with that observed from the Lageos satellite laser ranging data: (17.3 mas, -61 degrees ). Although the amplitudes are nearly equal, large phase discrepancies exist between the atmospheric and this observed value. The resolution of this discrepancy awaits a better knowledge of the seasonal angular momentum budget of the Earth's surface fluid elements. Copyright 1991 by the American Geophysical Union.

The critical parameter determining the existence of ice-covered lakes is the existence of peak seasonal temperatures above freezing. The peak temperature occurs at the subsolar point at perihelion. If there was a source of ice to provide meltwater, liquid water habitats could have been maintained under relatively thin ice covers for up to 700 million years after mean global temperatures fell below the freezing point. At this point, the mean annual temperature is 227 K, and the pressure of atmospheric CO (sub 2) is about 0.5 bar. Without the presence of stable bodies of liquid water, it is not clear what mechanisms were responsible for the removal of this remaining CO (sub 2) . From a biological point of view, it is found that the duration of liquid water habitats on early Mars exceeds the upper limit on the time required for the origin of life on Earth. In modeling such lakes, experimental data derived from the investigation of dry valley lakes in Antarctica is utilized. (Auth. mod.)

AN - 36405920; 3050 AB - PURPOSE: Design, development, and implementation of a project to place in orbit a research laboratory for scientific experimentation, technology development, and stimulation of commercial space enterprises are proposed. The project would involve a joint venture including the United States, Canada, the European Space Agency (ESA), and Japan. The baseline Space Station Freedom would consist of four major elements. The human-occupied base would fly in low Earth orbit from 278 kilometers (km) (150 nautical miles (n.m.)) to 500 km (270 n.m.). The normal operating altitude would be 463 km (250 n.m.). Flying at an orbital velocity of 18,000 miles per hour, the manned base would circumnavigate the Earth approximately every 90 minutes. An ESA Free Flying Laboratory would fly in approximately the same orbit. The ESA laboratory, designed for microgravity experiments, would be serviced periodically, either at the manned base or by ESA's Hermes spacecraft. Two other platforms would fly in sun-synchronous polar orbits approximately 705 km (380 n.m.) above the Earth. Space Station Freedom would be assembled in orbit over a four-year period beginning early in 1995 and ending in late 1999; Freedom is being designed for a lifetime of not less than 30 years. The Space Station would serve multiple functions: materials processing research would be conducted, and products not producible on Earth due to the adverse influences of gravity would be manufactured. The Space Station would also serve as a laboratory with a unique vantage point for advanced research in such fields as astrophysics, solar system exploration, Earth sciences, life sciences, and remote sensing. POSITIVE IMPACTS: The United States would be able to continue its leadership in space exploration and utilization and to provide a mechanism for international cooperation in space. NEGATIVE IMPACTS: Accidental inadvertent reentry of space station components could cause injury to property and loss of life; the possibility of this occurrence would be extremely remote.

AN - 72779450; 11536480 AB - In Drosophila, the establishment of regional commitments along most of the anterior/posterior axis of the developing embryo depends on two clusters of homeotic genes: the Antennapedia complex (ANT-C) and the bithorax complex (BX-C). The red flour beetle has a single complex (HOM-C) representing the homologues of the ANT-C and BX-C in juxtaposition. Beetles trans-heterozygous for two particular HOM-C mutations spontaneously generate a large deficiency, presumably by an exchange within the common region of two overlapping inversions. Genetic and molecular results indicate that this deficiency spans at least the interval between the Deformed and abdominal-A homologues. In deficiency homozygous embryos, all gnathal, thoracic and abdominal segments develop antennal appendages, suggesting that a gene(s) has been deleted that acts to distinguish trunk from head. There is no evidence that beetles have a homologue of the segmentation gene fushi tarazu of similar genomic location and function. On the basis of the genetic tractability, convenient genome size and organization of Tribolium, and its relatively long phylogenetic divergence from Drosophila (>300 million years), we have integrated developmental genetic and molecular analyses of the HOM-C. We isolated about 70 mutations in the complex representing at least six complementation groups. The homeotic phenotypes of adults and lethal embryos lead us to believe that these beetle genes are homologous with the Drosophila genes indicated in Fig. 1 (see text).

AN - 72776683; 11537089 AB - Upon resupply of exogenous nitrogen to nitrogen-stressed plants, uptake rate of nitrogen is enhanced relative to nonstressed plants. Absorption of nitrogen presumably is dependent on availability of carbohydrates in the roots. A buildup in soluble carbohydrates thus should occur in roots of nitrogen-stressed plants, and upon resupply of exogenous nitrogen the increased uptake rate should be accompanied by a rapid decline in carbohydrates to prestress levels. To evaluate this relationship, three sets of tobacco plants growing in a complete hydroponic solution containing 1.0 mM NO3- were either continued in the complete solution for 21 d, transferred to a minus-nitrogen solution for 21 d, or transferred to a minus-nitrogen solution for 8-9 d and then returned to the 1.0 mM NO3- solution. These nitrogen treatments were imposed upon plants growing at photosynthetic photon flux densities of 700 and 350 micromoles m-2 s-1. Soluble carbohydrate levels in roots increased during onset of nitrogen stress to levels that were fourfold greater than in roots of non-stressed plants. Following resupply of external nitrogen, a rapid resumption of nitrogen uptake was accompanied by a decline in soluble carbohydrates in roots to levels characteristic of nonstressed plants. This pattern of soluble carbohydrate levels in roots during onset of and recovery from nitrogen stress occurred at both irradiance levels. The response of net photosynthetic rate to nitrogen stress could be expressed as a nonlinear function of concentration of reduced nitrogen in leaves. The net photosynthetic rate at a given concentration of reduced nitrogen, however, averaged 10% less at the lower than at the higher irradiance. The decline in net photosynthetic rate per unit of reduced nitrogen in leaves at the lower irradiance was accompanied by an increase in the nitrate fraction of total nitrogen in leaves from 20% at the higher irradiance to 38% at the lower irradiance.

Y-82192 and Y-86032 are anorthositic lunar meteorites rich in Al2O3 and CaO and poor in FeO, MgO and incompatible elements. Although these meteorites are similar in composition to each other and other anorthositic lunar meteorites, they are distinct in several key compositional characteristics. Y-793274 is a basaltic lunar meteorite rich in FeO, MgO, Sc, Cr, Co, and incompatible elements, and poor in Al2O3 and CaO compared to anorthositic lunar meteorites. It is similar in many ways to lunar meteorite EET87521 which is also a basaltic breccia. It is distinct from EET87521 in its higher proportion of highland material, its meteoritic contamination and regolith glass, and in the composition of its dominant basalt component. Y-793274 contains 65-75% magnesian VLT basalt, while EET87521 consists of ferroan VLT basalt. The eleven lunar meteorites probably represent eight distinct falls. Four are anorthositic and four are basaltic. This 50-50 proportion of highlands-mare material contrasts strongly with the 83-17 proportion derived from photogeologic mapping. The dominance of VLT basalt among lunar meteorites contrasts with its scarcity among Apollo samples. (Auth.)

The global average delta (super 13) C (sub PDB) from these measurements (n = 208) was -47.20 + or - 0.13%o. The lowest mean annual delta (super 13) C value of-47.61 + or - 0.14 per mil was measured at Point Barrow with values increasing to -47.03 + or - 0.14 per mil at Cape Grim. The seasonal cycle in the delta (super 13) C of CH (sub 4) was greatest at Point Barrow, with an amplitude of 0.5 per mil, and varied inversely with concentration. The isotopic fractionation during CH (sub 4) oxidation is calculated to be 0.993 + or - 0.002 based on the measured CH (sub 4) concentration and delta (super 13) C values. The (super 14) C content of atmospheric CH (sub 4) , measured at monthly intervals at the Olympic Peninsula site between 1987 and 1989, is increasing at 1.4 + or - 0.5 pM yr (super -1) , primarily owing to (super 14) CH (sub 4) release from nuclear reactors. The global average (super 14) C content of 122 pM for CH (sub 4) implies a fossil methane source strength that is 16% of the total source. The global mean delta (super 13) C of -47.2 per mil, when coupled with the (super 14) C results, implies that approximately 11% of the total CH (sub 4) release rate is derived from biomass burning. These results indicate for a total CH (sub 4) source of approximately 550 Tg yr (super -1) that natural gas release accounts for approximately 90 Tg yr (super -1) and biomass burning yields approximately 60 Tg yr (super -1) . Preliminary analyses of the delta (super 13) C data using a three-dimensional chemical tracer model indicate that the observed meridional gradients in the annual average delta (super 13) C and concentration of CH (sub 4) are most closely matched with a CH (sub 4) source scenario in which 11% of the CH (sub 4) is derived from biomass burning.

The data bases were developed by integrating extensive and eclectic information on the cultivation of rice in all 103 rice-producing countries of the world. The geographic distribution of rice-growing locations was developed by combining a 1 degrees resolution land-use data base identifying rice-farming regimes, a 1 degrees resolution data base of countries of the world, and country statistics on areas of annual rice harvest available from the U. N. Food and Agriculture Organization. The seasonal distribution of cultivated rice areas was derived via the integration of the data base on rice-growing locations with information on cultivation activities and rice cropping practices for each rice-producing country of the world; this information included seasonal rice-cropping calendars for individual countries and statistics or estimates of the seasonal distribution of annual harvest areas in each crop cycle. Since the causes of the variability in methane fluxes from flooded rice fields have yet to be quantified, we did not attempt a new estimate of the role of rice cultivation in the global emission of methane. We evaluate, instead, the temporal and spatial distribution of emissions from a hypothetical annual source of 100 Tg methane. In 1984, 1475 X 10 (super 9) m (super 2) of rice was harvested in 103 countries. Although rice cultivation extends from about 50 degrees N to 50 degrees S, 48% of the harvest area is confined to a narrow subtropical zone from 30 degrees N to 20 degrees N, while another 35% is harvested in the 10 degrees zones directly to the north and south. Globally, about 60% of the harvested rice area is managed under a triple rice crop system, approximately 15% is double cropped, and 25% is harvested from fields planted for rice once a year. In China and India, which together account for 52% of the world's harvest area, rice is harvested predominantly under a triple-crop system. These patterns suggest that much of the potential for multiple rice cropping is currently exploited. In this analysis, methane emission is proportional to the area and duration of each harvest so that the seasonal, zonal and country patterns of annual methane emission mimic the distribution of rice-harvest areas. Although rice is grown throughout the year, the close coupling of rice cultivation with climate results in the concentration of about 55% of the annual methane emission into four months from July through October and almost half the total emission in latitudes between 30 degrees N and 20 degrees N.

The consequences of a global sea level rise would be spatially non-uniform because of local or regional vertical crustal movements, differential resistance to erosion, varying wave climates, and changeable longshore currents. Although many factors can influence sea level, leading to a noisy record, various studies utilizing tide-gauge data find an average global rate of sea level rise of 1-2 mm/yr, over the last 100 years. This trend is part of a general rise over the last 300 years, since the low point of the Little Ice Age. Sea level rise may accelerate 3-8 times over present rates, within the next century. The permanently inundated coastal zone would extend to a depth equivalent to the vertical rise in sea level. Major river deltas, coastal wetlands and coral islands would be most affected. Episodic flooding by storm waves and surges would penetrate even farther inland. Beach and cliff erosion will be accentuated. Saltwater penetration into coastal aquifers and estuaries could contaminate urban water supplies and affect agricultural production. Research on relative risks and impacts of sea level rise on specific localities is still at an early stage. Development of a global coastal hazards data base, intended to provide an overview of the relative vulnerabilities of the world's coastlines, is described in this paper. To date, information on seven variables, associated with inundation and erosion hazards, has been compiled for the U.S., and parts of Canada and Mexico. A coastal vulnerability index (CVI) has been designed to flag high risk coastal segments. Preliminary results are presented for the eastern United States, as a test case (DBO).

AN - 72786946; 11538270 AB - An electron-microscopic cytochemical method was used to localize diamine oxidase (DAO) in pea and polyamine oxidase (PAO) in maize (Zea mays L.). The method, based on the precipitation of amine-oxidase-generated H2O2 by CeCl3, was shown to be specific for DAO and PAO and permitted their localization in plant tissues with a high degree of resolution. Both enzymes are localized exclusively in the cell wall. Both DAO- and PAO-activity staining is most intense in the middle lamellar region of the wall and in cells exhibiting highly lignified walls. The oxidases could provide H2O2 for peroxidase-mediated cross-linking reactions in the cell wall and may, in this capacity, play a role in the regulation of plant growth.

This oceanic basement is intruded by Early Jurassic dikes that are coeval with hypabyssal and plutonic rocks within the Smartville and Slate Creek complexes. These dikes have geochemical characteristics reflecting a depleted and metasomatized source, as commonly observed in modern fore-arc settings and incipient volcanic arcs, and are interpreted to be the conduits for the Early Jurassic arc volcanism, which was built on and across the disrupted oceanic basement. Late Jurassic sheeted dikes intruding the Smartville complex have basaltic compositions compatible with an intra-arc or back-arc origin and indicate that a spreading event occurred within the arc in early Late Jurassic time. These interpretations support models for a complex multistage evolution via episodic magmatism and deformation within a single ensimatic Jurassic arc terrane west of the North American continent.

The Copernican System craters Aristillus and Autolycus are to the north; a ray from one of them crosses the landing site and had been suggested prior to the Apollo 15 mission as a source of material that could be used to date these craters. Autolycus, the older of the two, is in a particularly appropriate terrain and is the most likely source of the 2.1 Ga heating and delivery event. With this calibration point, and if Autolycus really is a Copernican crater, the Copernican System lasted twice as long as has previously been suggested. Furthermore, the Moon was not subjected to a constant cratering rate over the past 3 b.y.; the average rate in the preceding Eratosthenian must have been twice that in the Copernican.

Volatile molecules like H (sub 2) O are significantly more abundant than sodium in any of the proposed external atmospheric sources. Source mechanisms which derive atoms from the surface should favor abundant elements in the regolith. It is therefore puzzling that the Apollo ultraviolet spectrometer experiment set limits on the density of oxygen of N (sub O) < 5 X 10 (super 2) cm (super -3) , and that the Apollo Lunar Atmospheric Composition Experiment data imply N (sub O) < 50 cm (super -3) above the subsolar point. These limits are surprisingly small relative to the measured value for sodium. A simple consideration of sources and sinks predicts significantly greater densities of oxygen. It is possible but doubtful that the Apollo measurements occurred during an epoch in which source rates were small. A preferential loss process for oxygen on the darkside of the Moon is considered in which ionization by electron capture in surface collisions leads to escape through acceleration in the local electric field. Cold trapping in permanently shadowed regions as a net sink is considered and discounted, but the episodic nature of cometary insertion may allow formation of ice layers which act as a stabilized source of OH. On the basis of an assumed meteoroid impact source we predict a possible emission brightness of approximately 50 R in the OH(A - X)(0,0) band above the lunar bright limb. A very uncertain small comet source of H (sub 2) O could raise this value by more than two orders of magnitude. Copyright 1991 by the American Geophysical Union.

A Controlled Ecological Life Support System (CELSS) relies on the air revitalization, water purification and food production capabilities of higher plants to rejuvenate human wastes and replenish the life support materials. The key processes in such a system are photosynthesis, whereby green plants utilize light energy to produce food and oxygen while removing CO sub(2) from the atmosphere, and transpiration, the evaporation of water from the plant. CELSS research has emphasized the food production capacity and efforts to minimize the area/volume of higher plants required to satisfy all human life support needs. Plants are a dynamic system capable of being manipulated to favour the supply of individual products as desired. The size and energy required for a CELSS that provides virtually all human needs are determined by the food production capacity. Growing conditions maximizing food production do not maximize transpiration of water; conditions favoring transpiration and scaling to recycle only water significantly reduces the area, volume, and energy inputs per person. Likewise, system size can be adjusted to satisfy the air regeneration needs. Requirements of a waste management system supplying inputs to maintain maximum plant productivity are clear. The ability of plants to play an active role in waste processing and the consequence in terms of degraded plant performance are not well characterized. Plant-based life support systems represent the only potential for self sufficiency and food production in an extra-terrestrial habitat.

AN - 72796042; 11537624 AB - In current Mars scenario descriptions, an entire mission is estimated to take 500-1000 days round trip with a 100-600 day stay time on the surface. To maintain radiation dose levels below permissible limits, dose estimates must be determined for the entire mission length. With extended crew durations anticipated on Mars, the characterization of the radiation environment on the surface becomes a critical aspect of mission planning. The most harmful free-space radiation is due to high energy galactic cosmic rays (GCR) and solar flare protons. The carbon dioxide atmosphere of Mars has been estimated to provide a sufficient amount of shielding from these radiative fluxes to help maintain incurred doses below permissible limits. However, Mars exploration crews are likely to incur a substantial dose while in transit to Mars that will reduce the allowable dose that can be received while on the surface. Therefore, additional shielding may be necessary to maintain short-term dose levels below limits or to help maintain career dose levels as low as possible. By utilizing local resources, such as Martian regolith, shielding materials can be provided without excessive launch weight requirements from Earth. The scope of this synopsis and of Ref. 3 focuses on presenting our estimates of surface radiation doses received due to the transport and attenuation of galactic cosmic rays and February 1956 solar flare protons through the Martian atmosphere and through additional shielding provided by Martian regolith.

AN - 72790175; 11537121 AB - The majority of the environmental factors which comprise the spacecraft and space suit environments can be controlled at "Earth normal" values, at optimum values, or at other values decided upon by spacecraft designers. Factors which are considered in arriving at control values and control ranges of these parameters include physiological, engineering, operational cost, and safety considerations. Several of the physiological considerations, including hypoxia and hyperoxia, hypercapnia, temperature regulation, and decompression sickness are identified and their impact on spacecraft and space suit atmosphere selection are considered. The past experience in controlling these parameters in U.S. and Soviet spacecraft and space suits and the associated physiological responses are reviewed. Current areas of physiological investigation relating to environmental factors in spacecraft are discussed, particularly decompression sickness which can occur as a result of change in pressure from Earth to spacecraft or spacecraft to space suit. Physiological considerations for long-term lunar or Martian missions will have different impacts on atmosphere selection and may result in the selection of atmospheres different than those currently in use.

Consideration of oxidizing/reducing entities in relationship to other compositional, structural, and energetic factors. AN - 72789546; 11538371 AB - The rates (previously reported) for the air oxidation of hydrazine on kaolinite and substituent oxides of kaolinite showed a complex dependence on the relative amounts of several structural oxidizing/reducing entities within the reaction-promoting solids. The rates indicated an important role of the clay but no dominant role of any one of the oxidizing/reducing entities. In this paper we review (a) the reaction-promoting activity of these centers as studied in other systems, (b) various spectroscopic results showing interaction between these entities in clays, and (c) reported spectroscopic studies of the complexation between hydrazine and aluminosilicate surfaces as a whole, in an effort to propose a mechanism for the reaction. Whereas some uncertainties remain, the present synthesis concludes that a mechanism operating through single electron/hole transfers and hydrogen atom transfers by discrete centers is adequate to explain the observed rate behaviors including the observed second order dependence of the oxidation rate on catalyst amount. The effects of these operations on the catalyst can result in no alteration of, or complete or partial electronic relaxation of its contingent of trapped separated charge pairs.

AN - 72787330; 11537128 AB - Crewmembers on missions to the Moon or Mars will be unavoidably exposed to ionizing radiation as they pass through the Van Allen belts and the Galactic Cosmic Ray (GCR) flux. There is the possibility for exposure to proton radiation from Solar Particle Events (SPE). Using absorbed doses and ICRP 26, Linear Energy Transfer (LET) -dependent quality factors, the following dose-equivalents are estimated: In a spacecraft with 0.75 cm aluminum walls (2 g/cm2) at solar minimum, the lunar round trip dose-equivalent is less than 0.05 Sv. During a Mars mission the estimated dose-equivalents are: outbound (Van Allen Belts) or = 3) and target fragments with average quality factors of 10.3 and 20 respectively. The biological effectiveness of these radiations is poorly understood; so the quality factors are set at conservatively very high values. The entire concept of absorbed dose/quality factor/dose-equivalent as applied to GCR must be reconsidered.

AN - 72785086; 11538277 AB - The role of auxin redistribution in the graviresponse of the leaf-sheath pulvinus of oat (Avena sativa L.) was assessed using 3H-indole-3-acetic acid (3H-IAA) preloaded into isolated pulvini. When pulvini were totally isolated from subtending nodal tissue as well as leaf-sheath and internode, gravistimulation failed to induce an asymmetric growth response. Presence of either the nodal tissue or the internode/leaf-sheath tissue was sufficient to restore a normal graviresponse. Gravistimulation of totally isolated pulvini inhibited basipetal export of label (i.e., 3H-IAA) without generating any asymmetry of label within the pulvinus. In contrast, gravistimulation of pulvini with nodes intact generated an asymmetric distribution of label (initiation by 1 h; final ratio, lower/upper = 1.5) as well as the upward bending response. The kinetics of formation of the asymmetry of label paralleled the kinetics of initiation of the asymmetric growth response. The addition of 0.1 M sucrose to all agar blocks shortened both the time to initiation of label redistribution and the time to initial upward bending. However, sucrose did not change the final magnitude of label asymmetry although it increased the final steady state bending rate four fold. The inhibitors of polar auxin transport N-1-naphthylphthalamaic acid (NPA), 2,3,5-triiodobenzoic acid (TIBA), morphactin, naringenin, kaempferol and myricetin all significantly decreased the bending response of oat pulvini, but this inhibition was less than 50%. In contrast, TIBA and naringenin (each at 100 micromoles), effectively eliminated the redistribution of label, but did not eliminate the bending response. These results indicate that the active basipetal export of auxin is inhibited by gravistimulation of the oat pulvinus, while active lateral transport is induced. It is concluded that, while lateral transport of auxin occurs following gravistimulation, it is not necessary for a graviresponse. Other processes, such as localized changes in tissue responsiveness or the conversion of conjugated hormone to free (active) hormone, may suffice to drive the graviresponse.

AN - 72784602; 11537170 AB - Galactose inhibits auxin-induced growth of Avena coleoptiles by at least two mechanisms. First, it inhibits auxin-induced H(+)-excretion needed for the initiation of rapid elongation. Galactose cannot be doing so by directly interfering with the ATPase since fusicoccin-induced H(+)-excretion is not affected. Secondly, galactose inhibits long-term auxin-induced growth, even in an acidic (pH 4.5) solution. This may be due to an inhibition of cell wall synthesis. However, galactose does not reduce the capacity of walls to be loosened by H+, given exogenously or excreted in response to fusicoccin.

AN - 72779142; 11543591 AB - The assumption that the acridine orange (AO) color reaction may be used as an index of physiological activity was investigated in laboratory grown Escherichia coli. Spectrofluorometric observations of purified nucleic acids, ribosomes and the microscopic color of bacteriophage-infected cells stained with AO confirmed the theory that single-stranded nucleic acids emit orange to red fluorescence while those that are double-stranded fluoresce green in vivo. Bacteria growing actively in a rich medium could be distinguished from cells in stationary phase by the AO reaction. Cells from log phase appeared red, whereas those in stationary phase were green. However, this differentiation was not seen when the bacteria were grown in a minimal medium or when a variation of the staining method was used. Also, shifting bacteria in stationary phase to starvation conditions rapidly changed their AO staining reaction. Boiling and exposure to lethal concentrations of azide and formalin resulted in stationary-phase cells that appeared red after staining but bacteria killed with chlorine remained green. These findings indicate that the AO staining reaction may be suggestive of physiological activity under defined conditions. However, variables in staining and fixation procedures as well as uncertainties associated with mixed bacterial populations in environmental samples may produce results that are not consistent with the classical interpretation of this reaction. The importance of validating the putative physiological implications of this staining reaction is stressed.

AN - 72778689; 11538178 AB - The phospholipid and Ca2+ dependent protein kinase (PKC) plays an essential role in a variety of cellular events. Inhibition of PKC was shown to arrest growth in tumor cell cultures making it a target for possible antitumor therapy. Calphostins are potent inhibitors of PKC with high affinity for the enzyme regulatory site. Structural characteristics of calphostins, which confer the inhibitory activity, are investigated by comparing their optimized structures with the existing models for PKC activation. The resulting model of inhibitory activity assumes interaction with two out of the three electrostatic interaction sites postulated for activators. The model shows two sites of hydrophobic interaction and enables the inhibitory activity of gossypol to be accounted for.

AN - 72777119; 11537125 AB - For the first manned flight of Hermes there will be a capability of performing EVA. The European EVA Space Suit will be an anthropomorphic system with an internal pressure of 500 hPa of pure oxygen. The pressure reduction from the Hermes cabin pressure of 1013 hPa will induce a risk for Decompression Sickness (DCS) for the EVA crewmember if no adequate protective procedures are implemented. Specific decompression procedures have to be developed. From a critical review of the literature and by using knowledge gained from research conducted in the past in the fields of diving and aerospace medicine safe protective procedures are proposed for the European EVA scenario. An R factor of 1.2 and a tissue half-time (t1/2) of 360 minutes in a single-tissue model have been identified as appropriate operational values. On the basis of an acceptable risk level of approximately 1%, oxygen prebreathing times are proposed for (a) direct pressure reduction from 1013 hPa to a suit pressure of 500 hPa, and (b) staged decompression using a 700 hPa intermediate stage in the spacecraft cabin. In addition, factors which influence individual susceptibility to DCS are identified. Recommendations are also given in the areas of crew selection and medical monitoring requirements together with therapeutic measures that can be implemented in the Hermes scenario. A method for demonstration of the validity of proposed risks and procedures is proposed.

AN - 72776119; 11537127 AB - During the French-Soviet space mission "Aragatz," the experiment CIRCE (Compteur Integrateur de Rayonnement Complexe dans l'Espace) recorded the dose rate and quality factor values inside the MIR station. This paper presents results obtained with a new active dose equivalent meter based on microdosimetric techniques and using a low pressure tissue equivalent proportional counter. In terms of lineal energy CIRCE device works in the 0.2-1200 keV micrometer-1 range in tissue. Preliminary studies were performed in photon, neutron and heavy ion beams, and in the real stratosphere cosmic radiation field. Long term measurements on-board MIR station from December 1988 to April 1989 gave an average quality factor value equal to 1.9 +/- 0.3. Through the South Atlantic Anomaly (SAA), the quality factor was equal to 1.4. The temporal orbital variations of the dose rates and quality factors have been established in space dosimetry for the first time.

We also observed the 2(02)-1(01) transition of vinyl cyanide previously identified in TMC-1 by Matthews and Sears (1983b). The detection of vinyl cyanide and the non-detection of ethyl cyanide in TMC-1 are consistent with gas phase ion-molecule chemical models, and there is thus no necessity of invoking grain surface synthesis for vinyl cyanide in cold clouds.

Reaction kinetics on natural kaolinites, halloysites, and model substituent layers with varying iron and titanium oxide and O- center contents. AN - 72773013; 11538370 AB - Air oxidation of hydrazine was studied by using a group of kaolinites, halloysites, and substituent oxides as models for the tetrahedral and octahedral sheets. The rate was found to be linear with oxygen. The stoichiometry showed that oxygen was the primary oxidant and that dinitrogen was the only important nitrogen-containing product. The rates on kaolinites were strongly inhibited by water. Those on three-dimensional silica and gibbsite appeared not to be. That on a supposedly layered silica formed from a natural kaolinite by acid leaching showed transitional behavior--slowed relative to that expected from a second-order reaction relative to that on the gibbsite and silica but faster than those on the kaolinites. The most striking result of the reaction was the marked increase in the rate of reaction of a constant amount of hydrazine as the amount of clay was increased. The increase was apparent (in spite of the water inhibition at high conversions) over a 2 order of magnitude variation of the clay weight. The weight dependence was taken to indicate that the role of the clay is very important, that the number of reactive centers is very small, or that they may be deactivated over the course of the reaction. In contrast to the strong dependence on overall amount of clay, the variation of amounts of putative oxidizing centers, such as structural Fe(III), admixed TiO2 or Fe2O3, or O- centers, did not result in alteration of the rate commensurate with the degree of variation of the entity in question. Surface iron does play some role, however, as samples that were pretreated with a reducing agent were less active as catalysts than the parent material. These results were taken to indicate either that the various centers interact to such a degree that they cannot be considered independently or that the reaction might proceed by way of surface complexation, rather than single electron transfers.

Findings from the initial survey show that support for NIEI appears to be strong among the organizations surveyed and there is a significant level of cooperation between NIEI members and other organizations in developing and conducting programs. Heavily focused towards science, engineering, mathematics, and technology achievement, NIEI activities appear to be aligned with the national education goals. There are some areas for improvement. The majority of programs are targeted fairly late in the educational cycle and may be under emphasizing the formative years (i.e. pre-Kindergarten through elementary school). The number of initiatives geared towards adult literacy and adult-skills-enhancement is low. The number of critical assessment and systemic reform initiatives is also low.

A compilation of mean annual brightness temperature for the Greenland ice sheet based on Nimbus-5 ESMR (19 GHz) data is used to approximate the distribution of the accumulation rate in the area bounded by the dry snow line applying a simple conversion involving a polynomial function. This is compared with a compilation produced elsewhere using Nimbus-6 SCAMS (31 GHz) data applying a complex conversion involving the temperature dependence of the absorption coefficient, and with the latest compilation based on surface measurements of the accumulation rate.

Many antarctic eucrite, polymict eucrite, and basaltic clast samples show the abnormal trace element abundances with REE patterns exhibiting positive Ce anomalies, positive Eu anomalies, and low abundances of the remainder of the REEs, with the LREEs generally being at lower relative abundances than the HREEs. Most samples of crystalline clasts from the polymict eucrites LEW85300, LEW85302, and LEW85303 show the abnormal patterns, while the glassy matrixes of these meteorites show normal patterns. Exterior samples generally show more abnormal patterns (larger anomalies, greater depletions) than interior samples from the same meteorites. Comparison of all basaltic eucrite literature data combined with the authors' data shows that positive and negative Ce anomalies and positive Eu anomalies are found in about 61% of antarctic eucrite analyses, and are virtually unknown in non-antarctic eucrite analyses. Further, positive Ce anomalies and positive Eu anomalies are commonly associated with antarctic eucrites having low REE concentrations. Consideration of mineral/melt partition coefficients shows that it is unlikely that Ce anomalies are magmatic features from the HED parent body. Cerium anomalies on earth are generally restricted to the weathering zone, where the relative ease of oxidizing Ce to the +4 state allows for fractionation of Ce from the +3 REEs. (Auth. mod.)

Efflorescences from equilibrated ordinary chondrites consist of the hydrous Mg-carbonates nesquehonite (+/- hydromagnesite). X-ray diffraction and scanning electron microscope studies of efflorescences from LEW 85320 (H5) show abundant elongate prismatic crystals of nesquehonite (idiomorphic, not pseudomorphous after lansfordite), with minor local encrustations of hydromagnesite. Abundances of Na, K, Ca, and Rb in efflorescences from LEW 85320 suggest that the observed contents of these elements would require only modest fractionation of chondritic composition, whereas extensive fractionation would be required to derive the observed cation ratios from terrestrial sea-salts. Therefore, cations in evaporite minerals on antarctic meteorites are most likely not products of contamination by terrestrial (marine) salts. The Mg in the efflorescences probably originated from weathering of meteoritic olivine; other cations in the efflorescences are also of meteoritic provenance. (Auth. mod.)

The goal of the initiative is the prediction of the future behavior of this ice sheet and an assessment of its potential to collapse, rapidly raising global sea level. The multidisciplinary nature of WAIS reflects the complexity of the polar studies in many fields and meshes with future programs of both the U.S. and other countries. Important tasks in each discipline are described, and a coordinated schedule by which the majority of these tasks can be accomplished in 5 years is presented. (Auth. mod.)

The papers were prepared to accompany lectures given at the second SeaRISE workshop. The purpose of the workshop was to draft a Science and Implementation Plan of what was once called SeaRISE but is now called the West Antarctic Ice Sheet Initiative (WAIS). The plan appears as Vol.1 of this proceedings series. (Auth. mod.) JF - NASA Conference Publication A2 - Bindschadler, Robert A.

AN - 50476198; 1992-019628 AB - Fluctuations of glacier termini were studied in two regions in Alaska. In the Wrangell Mountains, 15 glaciers on Mount Wrangell, an active volcano, have been monitored over the past 30 years by surveying, photogrammetry and satellite. Results, which are consistent between different methods of measurement, indicate that the termini of most glaciers were stationary or retreating slightly. The terminus fluctuations of six tide-water and near- tide-water glaciers in College Fjord, Prince William Sound, have also been monitored since 1931 by surveying, photogrammetry and, most recently, by satellite imagery. Harvard Glacier, a 40 km long tide-water glacier, has been advancing at an average rate of nearly 20 m/yr since 1931, while the adjacent Yale Glacier has retreated at approximately 50 m/yr during the same period though, for short periods, both of these rates have been much higher. The striking contrast between the terminus behavior of Yale and Harvard Glaciers, which parallel each other in the same fjord, and are derived from the same snowfield, supports the hypothesis that their terminus behavior is largely the result of dynamic controls rather than changes in climate.

Similar approaches are used in order to investigate how well the models can be distinguished with the PVO data. Topography profiles across Aphrodite are compared to model spreading ridge profiles in order to further assess this model. Airy compensation depths and convection layer thicknesses are greater under eastern Aphrodite than western Aphrodite. Compensation depths in the east are greater than most estimates of lithospheric thickness, suggesting that this part of the ridge is dynamically supported. In parts of western Aphrodite, the spreading ridge model gravity provides a better fit to the data than either Airy compensation or mantle convection. Best-fit spreading rates are between 0.3 and 1.6 cm/yr. Airy compensation and mantle convection cannot be distinguished in most places using only PVO data.

The aerosol optical thickness tau sub(a) computed from the spectral Sun photometer measurements exhibited very high day-to-day variability ranging from approximately 0.1 to greater than 2.0 at 875 nm for both the wet and dry seasons. A gradient of decreasing tau sub(a) from north-to-south latitudes in the Sahel for the wet season, July-September, was observed, which may be caused jointly by increased washout owing to the gradient of increasing precipitation to the south and the location of source regions for dust in the north. The Angstrom wavelength exponent alpha was found to vary with the magnitude of the aerosol optical thickness, with values as high as 0.75 for very low tau sub(a), and values of 0.25 to 0.0 for high tau sub(a) conditions. Analysis of tau sub(a) data from this observation network suggests that there is a high spatial variability of tau sub(a) in the western Sahel region. Statistical analysis performed on the wet season data showed that at a 67 per cent confidence level the instantaneous values of tau sub(a) can be extrapolated approximately 270-400 km with an error tolerance of 50 per cent. Spatial variability in the dry season was of a similar magnitude. The ranges of variations in the NDVI in the Sahel region owing to commonly observed fluctuations in the aerosol optical thickness and aerosol size distribution were shown to be approximately 0.02 and 0.01, respectively.

At the heart of the SEI is permanent human presence beyond Earth orbit, which implies a new emphasis on life science research and life support system technology. Proposed bioregenerative systems for planetary surface bases will require carefully designed waste processing elements whose development will lead to streamlined and efficient systems for applications on Earth.

AN - 16519087; 2960633 AB - Ethyl alcohol's known ability to produce reliable decrements in pilot performance was used in a study designed to evaluate objective methods for assessing pilot performance. Four air carrier pilot volunteers were studied during eight simulated flights between San Francisco and Los Angeles in a Boeing 727-232 simulator. Two flights were conducted at each of four target blood alcohol levels, 0, 0.025, 0.050, and 0.075%. Each flight lasted about 1 h. Flights were conducted with full crews in a full simulated ATC environment. Data from direct observations and videotapes were used to examine discrete errors committed by the subjects. Total errors increased linearly and significantly with increasing blood alcohol. Planning and performance errors, procedural errors and failures of vigilance each increased significantly in one or more pilots and in the group as a whole.

AN - 16441319; 31251 AB - The optical flow field for an observer moving through a static environment depends on the observer's translational and rotational motion along with the distances to each surface point. We previously introduced 'subspace methods' for recovering 3D motion and depth from optical flow. These methods solve first for the observer's translation, independent of rotation and depth. In this paper, we discuss a particular implementation of this general theory, utilizing 'center-surround motion-opponent operators' that prefer motion in one direction in the center and motion in the opposite direction in the surround. Cells in visual area MT of the primate brain are known to have velocity-selective receptive fields with a similar center-surround spatial organization. We propose a theoretical framework for analyzing MT cell responses. JF - IEEE, COMPUTER SOCIETY, LOS ALAMITOS, CA (USA). pp. 95-100. 1991.

These reactions are O + OH arrow right O sub(2) + H, H + O sub(2) + M arrow right HO sub(2) + M, H + O sub(3) arrow right OH + O sub(2), and O + HO sub(2) arrow right OH + O sub(2). The energy lost from vibrationally excited OH (produced in the third reaction) by spontaneous emission is explicitly accounted for by using detailed kinetic models, so that only a portion of the exothermicity of this reaction is converted into heat. The heating rates due to these four reactions are found to rival the oxygen-related heating rates conventionally considered in models of the middle atmosphere, e.g., those due to O + O + M arrow right O sub(2) + M, O + O sub(2) + M arrow right O sub(3) + M, O sub(2) + hv arrow right O + O, and O sub(3) + hv arrow right O + O sub(2) The conversion of chemical potential energy into molecular translational energy (heat) by these odd-hydrogen reactions is a significant source of energy in the middle atmosphere which has not been previously considered.

AN - 16408045; 25612 AB - Computational fluid dynamics has been developed to the stage where it has become an indispensable part of aerospace research and design. In view of advances made in aerospace applications, the computational approach can be utilized for biofluid mechanics research. The incompressible Navier-Stokes solvers developed for aerospace applications have been applied to blood flow simulations such as the flow in the Penn State artificial heart. The flow through artificial heart devices is unsteady with moving geometry, which makes experimental study very difficult. Computational approach offers an alternative to provide detailed knowledge of the flowfield complementary to limited experimental measurements. In the present paper, computed results on the Penn State artificial heart will be used to demonstrate the potential of numerical simulation in analyzing the flow through artificial heart devices.

This work has progressed through initial requirements analysis, data relationships modeling, and documentation of a detailed conceptual design during the first nine months of the project, followed by a year of database development activity. A Beta-Test version of the system has just completed testing by a number of users at NASA ARC, Jet Propulsion Laboratory, Johnson Space Center, and Marshall Space Flight Center. Formal release of the operational system is planned for May 1991. This paper describes the design and implementation of the database system, provides an overview of it's operation from a typical user's perspective, and cites examples of data currently accessible in the Build 1 version. Plans for future enhancement of the database architecture, operation, and content to increase it's utility to the life support community are summarized. JF - SAE TRANS.

AN - 16390544; 20243 AB - A preliminary design of a Life Support System (LSS) has been developed as part of an ongoing comprehensive trade study of advanced processor technologies and systems architectures for an initial Lunar Outpost. The design is based on a mission scenario requiring intermittent occupation of a lunar surface habitat by a crew of four. It incorporates physiochemical process technologies that were considered for Space Station Freedom. A system-level simulation model of the design was developed to obtain steady-state material balances for each LSS processor. The mass flow rate predictions were used to obtained estimates of the LSS mass, volume, and power consumption by means of processor sizing correlations that were extrapolated from Space Station Freedom processor designs. The results were used to analyze the impacts of varying crew size, mission duration, processor operation strategy, and crew cabin loads on the LSS mass, average power consumption, volume, periodic resupply mass, and waste accumulation rates. The merits of the design were quantified relative to an open-loop LSS, and the implications of this assessment for future LSS research and technology development were identified. Finally, enhancements to the current analysis and questions to investigate during the next phase of the study were identified. JF - SAE TRANS.

AN - 16390245; 20232 AB - Solar particle events (SPE) are typically dominated by high-energy, low-linear energy transfer (LET) protons. Biological damage to astronauts during an SPE is expected to include a large contribution from high LET target fragments produced in nuclear reactions in tissue. We study the effects of nuclear reactions on integral LET spectra, behind typical levels of spacecraft and body shielding, for the historically largest flares using the high-energy transport code, BRYNTRN in conjunction with several biological damage models. The cellular track model of Katz provides an accurate description of cellular damage from heavy ion exposure. The track model is applied with BRYNTRN to provide an LET decomposition of survival and transformation rates for solar proton events. In addition, a fluence-based risk coefficient formalism is used to estimate Harderian gland tumor induction in rodents and cataractogenesis in rabbits from solar flares, and a LET analysis is used to assess the relative contribution from target fragments on these biological endpoints.

AN - 16390173; 20231 AB - Risk assessment in an environment of mixed radiation quality has been addressed in the past by use of the experimental parameter 'relative biological effectiveness' (RBE) or the related 'quality factor' (Q), which is defined for purposes of radiation protection. Herein, an alternative method, which is based on risk-related cross sections, is used to estimate risks of 'stationary' cataracts caused by radiation exposures during extended missions in deep space. Estimates of the even more important risk of late degenerative cataractogenesis are made on the basis of the limited data available. Data on lenticular opacification in the New Zealand white rabbit, an animal model from which such results can be extrapolated to humans, are analyzed by the Langley cosmic ray shielding code (HZETRN) to generate estimates of stationary cataract formation resulting from a Mars mission. The effects of the composition of shielding material and the relationship between risk and linear energy transfer (LET) are given, and the effects of target fragmentation on the risk coefficients are evaluated explicitly. The needs for further experimental lens opacification studies are discussed. JF - SAE TRANS.

AN - 16388452; 20261 AB - Conventional endurance exercise training that involves daily workouts of 1-2 hr duration during exposure to microgravity has not proven completely effective in ameliorating post-exposure orthostatic hypotension. Single bouts of intense exercise have been shown to increase plasma volume and baroreflex sensitivity in ambulatory subjects through 24 hr post-exercise and to reverse decrements in maximal oxygen uptake and syncopal episodes following exposure to simulated microgravity. These physiological adaptations to acute intense exercise were opposite to those observed following exposure to microgravity. These results suggest that the 'exercise training' stimulus used to prevent orthostatic hypotension induced by microgravity may be specific and should be redefined to include single bouts of maximal exercise which may provide an acute effective countermeasure against postflight hypotension.

AN - 16388024; 20263 AB - Changes in thermoregulation during spaceflight could result in an inability to tolerate ambient conditions or exercise tasks readily tolerated preflight. Weightlessness may alter heat production by changing metabolic rate, circadian rhythms of heat production, or work efficiency. It may impair heat loss by reducing convective and evaporative heat exchange. In addition, crewmembers may become less fit, less heat acclimated, hypohydrated, or have altered thermal sensitivity. Three scenarios are described: exercise conditioning in the mid deck, EVA, and emergency egress.

AN - 16386616; 20250 AB - Future manned habitats such as a Lunar or Martian outpost will require a high degree of self-sufficiency to minimize cost and dependency on resupply from Earth. Food and other life support expendables are major resupply items required for long-term habitation of planetary surfaces. By growing higher plants for food, resupply can be reduced and self-sufficiency increased. Additionally, higher plants provide carbon dioxide (CO sub(2)) removal and reduction, oxygen (O sub(2)) production, and water reclamation for human life support. Plants have been grown in the controlled environment of the Regenerative Life Support Systems (RLSS) Test Bed at Johnson Space Center. The systems performance in terms of supporting human life was determined for plant CO sub(2) assimilation, O sub(2) generation, and evapotranspiration rates, trace contaminant generation, and biomass production. In addition, test conditions and anomalies are described. JF - SAE TRANS.

AN - 16380290; 20226 AB - Conceptual designs for initial, intermediate, and advanced lunar base life support systems (LSS) are under development at JSC. The initial air revitalization, water recovery, and waste management subsystems are based on space station technologies. The intermediate system expands on the initial capabilities; for example, the initial waste management subsystem allows only for compacting and storing solid waste, while the intermediate waste management subsystem includes measures for recovering useful substances from the waste. The advanced system includes biological waste treatment and higher plants to be used for air revitalization and water processing. This paper describes the three systems and discusses the basis for selecting individual processes. System-level mass balances are used to illustrate the interaction of the air, water, and waste loops. The effect of introducing different waste treatment processes into the initial LSS is examined. The impact of biological waste treatment and higher plants on the air revitalization subsystem is also discussed. JF - SAE TRANS.

AN - 16380229; 20260 AB - Human locomotion is an essential capability for normal activity on Earth. It requires the largest muscle and bone mass in the body and this muscle activity normally determines cardio-respiratory capacity. Active individuals, including the astronaut population, usually take > 10 super(4) steps day super(-1) at rates of 1 - 3 steps sec super(-1) with foot ground forces of 1 - 1.4 body weight (B.W.) walking and 2-3 + B W. running, producing up to 300W equivalent work. Forces and energy levels are a function of mode (walk or run), B.W, velocity, and surface grade and consistency. Overground and treadmill (T.M.) locomotion are equivalent on Earth. In weightlessness, locomotion is impossible and, without exercise, there will be a rapid loss of muscle, bone, and cardio-respiratory capacity such that, after several months' spaceflight without exercise, most individuals will be unable to walk from strength loss. Currently, the only exerciser capable of providing locomotor activity in flight is a treadmill which must also provide a constant axial truncal force equivalent to B.W. Subject-driven treadmills can operate at a variety of controlled speeds but only at some minimum equivalent grade, and a motor-driven unit can be designed to operate over all practical speeds and equivalent grades. Both US and USSR programs have simple flight T.M.s. US T.M.s and instrumentation have been designed and prototypes demonstrated that provide performance equivalent to Earth units. Such designs, if properly utilized, should maintain locomotor and cardio-respiratory capacity during long flight at a level consistent with required postflight activities. JF - SAE TRANS.

Use of an infrared imaging camera with real-time video monitoring of the output significantly added to the scope, quality and interpretation of the test conduct and data, acquisition. Results of this test program have been effective in the thermal certification of a new insulation configuration and the '5000 Series' glove. In addition, the acceptable thermal performance of flight garments with visually deterioration insulation was successfully demonstrated, thereby saving significant inspection and garment replacement cost. This test program also established a new method for collecting data vital to improving crew thermal comfort in a cold environment. JF - SAE TRANS.

AN - 16377671; 20246 AB - In support of Space Station Freedom Phase C/D Environmental Control and Life Support Systems (ECLSS) regenerative systems development, comparative testing was performed on predevelopment hardware of competing technologies for each regenerative function. This testing was conducted by The Boeing Aerospace and Electronics Company (BAE) at Marshall Space Flight Center (MSFC) from late 1989 through early 1990. The purpose of the test program was to collect data on latest generation hardware in order to make final technology selections for each subassembly in the oxygen recovery and water reclamation strings. This paper discusses the testing performed, test results, and evaluation of these results relative to subsystem selections for CO sub(2) reduction, O sub(2) generation, potable water processing, hygiene water processing, and urine processing.

AN - 16362368; 2857080 AB - The effects of deep convection on the potential for forming ozone ("ozone production potential") in the free troposphere have been simulated for regions where the trace gas composition is influenced by biomass burning. Cloud dynamical and photochemical simulations based on observations in 1980 and 1985 Brazilian campaigns form the basis of a sensitivity study of the ozone production potential under differing conditions. The photochemical fate of pollutants actually entrained in a cumulus event of August 1985 during NASA/GTE/ABLE 2A (Case 1) is compared to photochemical ozone production that could have occurred if the same storm had been closer to regions of savanna burning (case 2) and forest burning (Case 3). In each case studied, the ozone production potential is calculated for a 24-hour period following convective redistribution of ozone precursors and compared to ozone production in the absence of convection.

The effect on several types of astronomical observation at night has been studied, considering different size distributions and amounts as well as particle shapes of the aerosols. The analysis is made not as a function of the absolute aerosol amount but in terms of the signal-to-noise ratios for a given amount of aerosol. The model is applied to conditions at the Wise Astronomical Observatory in the Negev desert and limiting backgrounds for spectroscopy, photometry, and photography of stars and extended objects have been calculated for a variety of signal-to-noise ratios. Applications to observations with different equipment at various distances from an urban area of any size are possible.

AN - 16231614; 2765511 AB - Over the past 30 yr, the U.S. Government has evolved a process for the safety review and launch approval of nuclear power sources (NPSs) proposed for launch into space. This process, which involves a number of governmental agencies, ensures that the various postulated accident scenarios are considered, that the responses of the NPSs to the accident environments are assessed, and that appropriate elements of the Federal Government are involved in the launch approval. This process has worked very well in the successful launches of 37 radioisotope thermoelectric generators and 1 reactor by the United States since 1961. Particular attention will be focused on the recent launch of the Galileo spacecraft.

AN - 16106231; 2662877 AB - Turbulence and heat fluxes in the marine atmospheric boundary layer (MABL) for the roll vortex regime, observed during the Genesis of Atlantic Lows Experiment (GALE) over the western Gulf Stream, have been studied. The spectral analysis suggests that cloud streets (roll vortices) are vertically organized convection in the MABL having the same roll scale for both the cloud layer and subcloud layer, and that the roll spacing is about three times the MABL depth. The roll circulations contribute significantly to the sensible (temperature) and latent heat (moisture) fluxes with importance increasing upward. The results suggest that the entrainment at the MABL top might affect the budgets of temperature and humidity fluxes in the lower MABL, but not in the unstable surface layer.

AN - 16090155; 2652950 AB - One hundred twelve plots were established in coastal scrub and slash pine flatwoods habitats on the John F. Kennedy Space Center (KSC) to evaluate relationships between the number of burrows and gopher tortoise (Gopherus polyphemus ) density. All burrows were located within these plots and were classified according to tortoise activity. Depending on season, bucket trapping, a stick method, a gopher tortoise pulling device, and a camera system were used to estimate tortoise occupancy. Correction factors (% of burrows occupied) were calculated by season and habitat type. Our data suggest that < 20% of the active and inactive burrows combined were occupied during seasons when gopher tortoises were active. Correction factors were higher in poorly-drained areas and lower in well-drained areas during the winter, when gopher tortoise activity was low. Correction factors differed from studies elsewhere, indicating that population estimates require correction factors specific to the site and season to accurately estimate population size.

AN - 16081003; 2631058 AB - Incident precipitation, throughfall and stemflow were collected to examine the importance of factors potentially determining net canopy element fluxes, and to quantify canopy exchange and dry deposition rates in a regenerating southern Appalachian forest. Net throughfall fluxes (throughfall minus precipitation transfers) showed consistent canopy effects on rainfall chemistry, with SO sub(4) super(2-), PO sub(4) super(3-), Cl super(-), K super(+), Ca super(2+) and Mg super(2+) added to rainfall by foliage, whereas NO sub(3) super(-)-N, NH sub(4) super(+)-N and H super(+) ions were absorbed from precipitation. Storm characteristics (event amount and duration) accounted for the largest portion of the variability in growing season net throughfall fluxes, suggesting that canopy exchange was the major mechanism of throughfall transfer.

AN - 16060848; 2620497 AB - An extensive biological and optical data set was collected during a 4 month cruise as part of the Research on Antarctic Coastal Ecosystem Rates (RACER) program conducted in coastal waters of the Antarctic Peninsula and adjacent open ocean waters of Drake Passage. Chlorophyll plus phaeopigment (Chl + Phaeo) concentration in the upper mixed layer ranged 2 orders of magnitude from 0.5 to 50 mg Chl + Phaeo/m super(3) during the study. The large variations in pigment correspond to variations in the beam attenuation coefficient at 660 nm (c sub(t)) ranging from 0.5 to > 2.5/m and in the diffuse attenuation coefficient (k sub(d)) for 441 nm ranging from 0.04 to > 1.0/m. Chl + Phaeo specific particulate bean attenuation and spectral absorption coefficients suggest that detrital contributions are relatively low and that pigment package effects are relatively important compared to low latitude observations. The combination of these effects causes low pigment specific absorption and scattering. JF - DEEP-SEA RES. (A OCEANOGR. RES. PAP.).

The environmental impact of this phenomenon has yet to be modeled and understood with confidence. Some models predict adverse effects impacting millions of people from Africa to the Indian subcontinent; others predict regional impacts, or do not aggregate to the level of large-scale and deleterious environmental consequences.

AN - 16046778; 2616718 AB - Measurements of bacterial sulfate reduction and dissolved oxygen (O sub(2)) in hypersaline bacterial mats (dominated by the cyanobacterium Microcoleus chthonoplastes)) from Baja California, Mexico, revealed that sulfate reduction occurred consistently within the well-oxygenated photosynthetic zone of the mats. This evidence that dissimilatory sulfate reduction can occur in the presence of O sub(2) challenges the conventional view that sulfate reduction is a strictly anaerobic process. At constant temperature, the rates of sulfate reduction in oxygenated mats during daytime were similar to rates in anoxic mats at night: thus, during a 24-hour cycle, variations in light and O sub(2) have little effect on rates of sulfate reduction in these mats.

AN - 16035802; 2609062 AB - Pollen stratigraphy from three peat sections near Yakutat, Alaska, suggests that lodgepole pine only recently arrived in southeastern Alaska. In contrast with this palynological interpretation, however, are lodgepole pine (Pinus contorta ) macrofossils that are present throughout one entire peat core. super(14)C dating by accelerator mass spectrometry confirms the establishment of lodgepole pine in this region of Alaska about 10,000 BP. The surprising disparity between the pollen and macrofossil results has important implications for paleomigration research. These results imply that the use of assigned pollen percentages to indicate the presence of a species within a region may not be valid, particularly where a species is at the edge of its geographic range. Comparison of the timing of the first appearance of lodgepole pine pollen from a dozen sections along the north Pacific coast suggests either a late Wisconsin refugium for this pine in southeastern Alaska or extremely rapid late-glacial coastal migration northwestward following ice retreat.

In each marsh, vegetation cover was determined before burning on 5 permanent 15 m transects in the greater than 0.5 m and less than 0.5 m layers and sampled biomass on 25 plots (0.25 m super(2)). Species composition one year after burning was similar to that before the fire in both Juncus) and Spartina marshes. Minor species tended to increase, but this was significant only in the less than 0.5 m layer. In mixed stands, fire appeared to favor Spartina bakeri . The sum of the cover values for each species in both marshes reestablished by one year after burning. Biomass did not recover as rapidly. Fire increased the ratio of live to dead biomass from 0.82 before burning to 1.85 one year after the fire in the Juncus marsh. In the Spartina marsh, the ratio increased from 0.80 before burning to 1.59 one year after burning.

Calculations of hydrogen peroxide in chemically coherent regions. AN - 15949270; 2530914 AB - Increasing global emissions of trace gases NO, CH sub(4), and CO, along with perturbations initiated by changes in stratospheric O sub(3) and H sub(2)O, may cause tropospheric hydrogen peroxide (H sub(2)O sub(2)) levels to change. Specific scenarios of CH sub(4)-CO-NO emissions and global climate changes are used to predict HO sub(2) and H sub(2)O sub(2) changes from 1985 to 2035 in a one-dimensional model that simulates different chemically coherent regions (e.g. urban, non-urban continental and marine mid-latitudes; marine and continental low latitudes).

The PC-based Digital Acoustic Control System (DACS) is a closed-loop system which precisely controls the spectrum in a realtime mode. The DACS makes the operation and control of high level acoustic testing simple and efficient compared to the open-loop manual control systems which are presently used in the United States. The control system includes integrated facility hardware such as control microphones, signal conditioners, realtime analyzer (RTA), shaper, high capacity power amplifiers, and acoustic horns and generators. The DACS communicates with both the realtime analyzer and the programmable shaper, and transfers test parameters between each sampling.

AN - 15923898; 2508614 AB - Recent analyses of long-term records of tropospheric ozone measurements in the Northern Hemisphere suggest that it is increasing at a rate of 1 to 2 percent per year. Because of this, it is argued that the amount of atmospheric warming due to increasing tropospheric ozone is comparable to, or possibly even greater than, the amount of warming due to the increase of carbon dioxide. Unlike all other climatically important trace gases, ozone is toxic, and increases in its concentration will result in serious environmental damage, as well as impairment of human health.

AN - 15853999; 2449866 AB - Irrigated rice provides an ideal breeding habitat for Anopheles freeborni , the western malaria mosquito, throughout California. In a 1985 study, it was determined that early-season rice canopy development, as monitored using remotely sensed data, could be used to distinguish between high and low mosquito producing rice fields. This distinction could be made over two months prior to peak mosquito production. It was also found that high-producing fields were located in an area characterized by a diversity of land use, including livestock pastures, whereas the low-producing fields were in an area devoted almost exclusively to the cultivation of rice. The ability to distinguish between high and low mosquito producing fields prior to peak mosquito production is important in terms of mosquito habitat surveillance and control.

AN - 15850287; 2458460 AB - Chief among the mechanisms thought to amplify the global climate response to increased concentrations of trace gases is the atmospheric water vapour feedback. Recently, it has been suggested that general circulation models used for evaluating climate change overestimate this response, and that increased convection in a warmer climate would actually dry the middle and upper troposphere by means of associated compensatory subsidence. We use some new satellite-generated water vapour data to investigate this question. We find that, as the hemispheres warm, increased convection leads to increased water vapour above 500 mbar in approximate quantitative agreement with the results from current climate models.

It is seen that chemically processed air may be identified over much of the Arctic lower stratosphere from early January to late February, with HCl depletions being larger in 1989 than in 1979. Near the latitude of the Arctic circle, there is important spatial and temporal variability in the extent of chemically processed air. There is some evidence for transport to mid-latitudes of processed air during these winters, but the HCl reductions are much smaller and more sporadic than those near the pole. At 62 and 42N, processed air is calculated to occur preferentially over the longitude regions from 60-120E and 270-330E.

Such mats are well-laminated and are dominated by the cyanobacterium Microcoleus chthonoplastes in saline ponds. At constant temperature, the sulphate reduction rates in oxygenated mats during daytime were similar to rates in anoxic mats at night. Thus, during a 24 h cycle, variations in light and oxygen had little effect on sulphate reduction rates in these mats. There are 33 references.

Substantial reductions in nitrate concentrations were brought about by the addition of 10 mg carbon per litre for 35 d. The disappearance of nitrate correlated with increases in numbers of denitrifying bacteria and dissolved nitrous oxide concentrations and with decreases in dissolved oxygen, suggesting that biological denitrification was the mechanism responsible. Microbial denitrification had a significant influence on nitrate concentrations in unconsolidated aquifers and remediation by organic infusion was feasible.

It is found that the perturbed optical depths at middle and higher latitudes of both hemispheres exhibited an exponential decay superimposed by a seasonal oscillation with maximum and minimum occurring in local winter and local summer, respectively. Microphysical processes and variation of the tropopause height alone cannot explain this seasonal change of optical depth. The magnitudes of the exponential component at higher latitudes were, in general, larger than those at lower latitudes. For optical depths in tropical regions, the seasonal oscillations were small and were disturbed by the eruption of Nevado del Ruiz on November 13, 1985. The increase in ratio of optical depth at 0.525 mu m to that at 1.02 mu m from about 2.0 at the beginning of 1985 to about 3.5 at the end of 1988 indicates the average size of aerosol particles in the stratosphere is diminishing since the eruption of El Chichon. The l/e folding time for El Chichon decay derived from the SAGE II data set is in reasonably good agreement with those derived by other methods.

AN - 80423518; 11541482 AB - Electrofusion of evacuolated with vacuolated mesophyll protoplasts of Nicotiana spec. was performed as part of the German Sounding Rocket Program (TEXUS). The results indicate a significant increase not only in the yield of 1:1 fusion products, but also in homo- and multifusion products. Heterokaryons obtained under microgravity have been shown to be viable to a higher degree with respect to their ability for light-dependent oxygen evolution (independent of other substrates than bicarbonate). Furthermore we were able to regenerate hybrid plants from suspensions of vacuolated and evacuolated protoplasts which were pulse-treated under microgravity. These expressed characteristics intermediate to those of the parental plants (Nicotiana tabacum (cv. Samsun), evacuolated; N. rustica, vacuolated).

AN - 80421952; 11541483 AB - The U.S. space program is undertaking a serious examination of new initiatives in human space exploration involving permanent colonies on the Moon and an outpost on Mars. Life scientists have major responsibilities to the crew, to assure their health, productivity, and safety throughout the mission and the postflight rehabilitation period; to the mission, to provide a productive working environment; and to the scientific community, to advance knowledge and understanding of human adaptation to the space environment. Critical areas essential to the support of human exploration include protection from the radiation hazards of the space environment, reduced gravity countermeasures, artificial gravity, medical care, life support systems, and behavior, performance, and human factors in an extraterrestrial environment. Developing solutions to these concerns is at the heart of the NASA Life Sciences ground-based and flight research programs. Facilities analogous to planetary outposts are being considered in Antarctica and other remote settings. Closed ecological life support systems will be tested on Earth and Space Station. For short-duration simulations and tests, the Space Shuttle and Spacelab will be used. Space Station Freedom will provide the essential scientific and technological research in areas that require long exposures to reduced gravity conditions. In preparation for Mars missions, research on the Moon will be vital. As the challenges of sustaining humans on space are resolved, advances in fundamental science, medicine and technology will follow.

The analysis of these 53 data sets includes constrained, continuous, piecewise-linear estimation of the site atmospheres and clocks; application of values and correlations from a self-consistent Earth orientation series derived from other VLBI data; and simultaneous estimation of site positions and velocities. From a solution that includes 21,007 observations with a fit of 40 ps in delay and 64 fs/s in delay rate, we have determined the horizontal velocities of seven sites with precisions of 0.5-2 mm/yr (1sigma standard deviation). The three VLBI sites within the Alaska-Aleutian subduction boundary zone (Yakataga, Kodiak, and Sand Point) have higher instantaneous velocities relative to eastern North America than the interior sites of Alaska (Fairbanks and Sourdough). The estimated velocity of Yakataga relative to Fairbanks is 37.8 + or - 1.3 mm/yr at N27 degrees W + or - 2 degrees . Modeling of the Yakataga data suggests that the observed motion is the result of elastic straining of the overriding plate due to a locked main thrust zone with a component of oblique slip. The estimated velocity of Kodiak relative to Fairbanks is 13.6 + or -0.8 mm/yr at N41 degrees W + or - 3 degrees ; this result is lower than the rate predicted on the basis of simple elastic dislocation models. The estimated velocity of Sand Point relative to Fairbanks is 6.4 + or - 0.9 mm/yr at N65 degrees W + or - 8 degrees . The component of this velocity in the plate direction, 3.5 + or - 1.1 mm/yr, is not consistent with either an aseismic slip model (i.e., no strain accumulation in the overriding plate) or a model in which the site is undergoing compressional strain (10.9 mm/yr at approximately N28 degrees W) due to simple subduction at the predicted orientation of Pacific plate convergence. In a North America-fixed reference frame, the estimated velocities of Fairbanks (1.5 + or - 0.5 mm/yr at S12 degrees E + or - 20 degrees ) and Sourdough (3.9 + or -1.0 mm/yr at S13 degrees W + or - 13 degrees ) are both southward. These results may imply motion of this region relative to stable North America, but more observations are required to reduce the uncertainties in the azimuths. The time evolution of the estimated site positions from VLBI in Alaska are, in general, consistent with constant velocity. However, in 1988 the Yakataga site showed a significant departure from the position predicted from a constant-velocity model obtained from the previously estimated position. This departure may be static displacement associated with two major strike-slip earthquakes that occurred in the Gulf of Alaska between the 1987 and 1988 measurement sessions.

The analysis is based on the precise modeling of the orbit dynamics of LAGEOS and includes the determination of other geodynamic and nonconservative force model parameters involved in the orbit determination problem at the centimeter level. Site velocities were recovered from station positions determined each calendar quarter using a network adjustment procedure which maintains the reference frame. Within the stable interior of tectonic plates, the recovered motions indicate good agreement with existing estimates of stress fields, particularly across northern Europe, the eastern Pacific, and in the Basin and Range province of North America. A comparison of the intersite motions for stations centrally located on separate plates between SLR and those implied by the NUVEL 1 geologic motion model yield a strong positive correlation of 0.989 and a 3-7% scale difference which may be attributable to recent changes in relative velocities or geologic time scale uncertainties. Sites located at or within 250 km of convergent plate boundaries have additional components of motion, indicating a need for further tectonic modeling beyond that provided by simple rigid plate motions. For lines crossing the north Atlantic, the San Andreas fault, and within the Basin and Range province, the geodesic rates determined by SLR are in good agreement with those determined by very long baseline interferometry, an alternative space geodetic technique.

The key factors influencing the accuracy are range noise, number of targets and their locations, system pointing capability, dwell time on the targets, orbital geometry, and gravity field uncertainties. GLRS is designed to provide range measurements with 10 mm or better accuracy, fire at a rate of 40 pulses-per-second, point over a cone extending to 50 degrees from nadir, and operate with a dwell time on individual targets of 2 s or less. Given a strain rate of 10 (super -14) /s, estimated GLRS accuracy parameters suggest that the deformation can be detected in less than a month if it extends over 100 km and in less than 6 months if it extends over 10 km.--Modified journal abstract.

First, an empirical relationship between chlorophyll a and DMS in surface seawater (Andreae and Barnard, 1984) is used with NASA coastal zone color scanner (CZCS) data for chlorophyll a pigment to derive a mean DMS flux for a region in the tropical North Atlantic for October 1980. This is compared with the sea-to-air flux derived from a one-dimensional photochemical model that reproduces boundary layer concentrations of O (sub 3) , CO, NO, and hydrocarbons measured on a cruise at the same location and time (Meteor 56/1). Both evaluations of DMS fluxes are in the range (2-7) X 10 (super 9) molecules DMS cm (super -2) s (super -1) and agree well with fluxes based on the seawater DMS concentration given by Barnard et al. (1982) for the Meteor cruise. The applicability of the results to strategies for satellite remote sensing of the tropospheric sulfur cycle is discussed. For some species (e.g., DMS) surface sensing of sources is feasible, but only in regions and seasons where phytoplankton pigment is a meaningful marker for biogenic emissions. The general applicability of ocean color to DMS determination awaits the development of an algorithm that can extract distributions of DMS emitting species from the optical signal. For other sulfur constituents (e.g., SO (sub 2) , COS) atmospheric measurements are appropriate for determining tropospheric distribution. Wind, moisture, cloud, precipitation, and temperature data are also required for complete characterization of the marine sulfur cycle. Copyright 1990 by the American Geophysical Union.

Relations between either the point or beam-averaged effective reflectivity (Z) and surface rain rate (R) were determined by a probability matching method. The cumulative density functions (CDF) of reflectivity and rain rate were matched at pairs of R, Z which give the same percentile contribution. Range-dependent Z-R relations were obtained by stratifying the Z data by range. Truncation of the Z distribution by too large a threshold caused the threshold rain rate retrieved from the radar data to exceed that in the matching gage distribution. Forcing a match between the mean rate measured by the gages and those retrieved by use of a set of trial Z-R equations provided for the adjustment of the final Z-R relation and compensated for the truncation. The radar- retrieved CDFs of rain rate then replicate the CDF of gage-measured rates nicely. The probability matching scheme produced a Z-R relation that agreed with the bias-adjusted relation, accounting for the approximate inverse relation between the effective reflectivity and beamwidth. The method implicitly includes climatological variations of drop size distribution and rain rate with height due to a variety of physical factors. Because of the sensitivity of the Z-R relation to beamwidth and viewing angle, it cannot be transferred either to airborne or spaceborne radars. The climatologically-tuned Z-R may be applied to smaller space- time domains than those for which they were developed as long as the PDF of Z closely approximates that for which the relation was developed. This occurs in tropical regimes and elsewhere when the day-to-day storms resemble the climatically-typical storm.

AN - 80414101; 11538297 AB - The process by which regulatory standards are established for drinking water contaminants is based on extrapolating animal toxicity data to humans using a standard mathematical model. The assumptions and judgments involved introduce a relatively high degree of uncertainty and conservativeness into both the qualitative and quantitative aspects of the process. Setting standards based on knowledge of specific mechanisms of carcinogenicity would decrease the uncertainty involved in risk assessment. Understanding these mechanisms is necessary for arriving at the most appropriate mathematical construct for calculating more rational standards.

AN - 62881650; ED339351 AB - An explosion of information has created a crisis for today's information age. How to use the best information resources, tools, and technology must be determined. To do this, leadership must exist at the interagency level to promote a coherent information policy. It is also important to find ways to educate users of information regarding the tools available to them. Advances in technology have resulted in efforts to shift from disciplinary and mission-oriented systems to decision support systems and personalized information systems. One such effort is being made by the Interagency Working Group on Data Management for Global Change (IAWGDMGC). Five federal agencies--the Department of Commerce (DOC), Department of Energy (DOE), National Aeronautics and Space Administration (NASA), National Library of Medicine (NLM), and Department of Defense (DOD)--have an on-going cooperative information management group, CENDI (Commerce, Energy, NASA, NLM, and Defense Information), which is meeting the challenge of coordinating and integrating their information management systems. Although it is beginning to be technically feasible to have a system with text, bibliographic, and numeric data online for the user to manipulate at the user's own workstation, it will require national recognition that the resource investment in such a system is worthwhile to promote its full development. It also requires close cooperation between the producers and users of the information--that is, the research and policy community, and the information community. National resources need to be mobilized in a coordinated manner to move the nation into the next generation of information support systems. (9 references) (Author/DB) AU - Carroll, Bonnie C.

In addition, we wanted to ascertain how satellite data from possible future missions might be made more useful. We were particularly interested in querying the exploration community, but some academic and governmental researchers were included for comparison. This note presents the results of our survey.

From a new study of earthquakes with magnitudes > or = 5.5 in southern and coastal central California during the years 1855-1983, it is concluded that, at least in this selected area of the world, no statistically significant long-term periodicities in earthquake frequency occur. The sample size used is about twice that used in comparable earlier studies of this region which concentrated on large earthquakes. Copyright 1990 by the American Geophysical Union.

In order to incorporate cloud effects, upwelling radiometric measurements at 90 GHz and three side bands near 183 GHz were used to retrieve water vapor profiles over the ocean surface. An algorithm incorporating a new technique of handling moderate cloud cover was illustrated for the profiling of both relative humidity and water vapor burden. It was shown that the retrieved relative humidity profiles reflect gross features of the corresponding profiles recorded by the radiosondes. However, the retrieval generally could not produce fine details of the observed profiles at altitudes where a rapid change in relative humidity occurred. For this reason, comparison of retrieved and observed values at a given altitude often yielded an appreciable root mean square (RMS) error. Profiling of water vapor burden, a parameter equivalent to total integrated water vapor above a certain altitude, resulted in much better agreement, as expected. The RMS error obtained from the results of the retrieval at the surface was comparable to that derived from the combination of measurements at 18 GHz and 21 GHz channels of the Scanning Multichannel Microwave Radiometer aboard the Nimbus 7 satellite.

AN - 80420271; 11536478 AB - The prebiotic formation of histidine (His) has been accomplished experimentally by the reaction of erythrose with formamidine followed by a Strecker synthesis. In the first step of this reaction sequence, the formation of imidazole-4-acetaldehyde took place by the condensation of erythrose and formamidine, two compounds that are known to be formed under prebiotic conditions. In a second step, the imidazole-4-acetaldehyde was converted to His, without isolation of the reaction products by adding HCN and ammonia to the reaction mixture. LC, HPLC, thermospray liquid chromatography-mass spectrometry, and tandem mass spectrometry were used to identify the product, which was obtained in a yield of 3.5% based on the ratio of His/erythrose.

Data from cores drilled in polar ice sheets show a remarkable correlation between past glacial-interglacial temperature changes and the inferred atmospheric concentration of gases such as carbon dioxide and methane. These and other paleoclimate data are used to assess the role of greenhouse gases in explaining past global climate change, and the validity of models predicting the effect of increasing concentrations of such gases in the atmosphere. Data from two Greenland ice cores, Camp Century and Dye 3, and from three antarctic cores, Vostok, Byrd, and Dome C, were used in this review. (Auth.)

Using these new parameters, models of the interiors of these planets show that their density distributions are very similar. This lends support to the conjecture that their compositions are similar as well. The models are indeed consistent with such a conjecture. The difference in the internal heat sources of these two planets may be due to the fact that heat transport from the interior of Uranus is inhibited by a statically stable interior.

The vertical profile of dimethylsulfide (DMS) during the wet season was found to be very similar to that measured during the dry season, suggesting little seasonal variation in DMS fluxes. The concentrations of hydrogen sulfide (H (sub 2) S) were almost an order of magnitude higher than those of DMS, which makes H (sub 2) S the most important biogenic source species in the atmospheric sulfur cycle over the Amazon Basin. Using the gradient-flux approach, we estimated the flux of DMS at the top of the tree canopy. The canopy was a source of DMS during the day, and a weak sink during the night. Measurements of sulfur gas emissions from soils, using the chamber method, showed very small fluxes, consistent with the hypothesis that the forest canopy is the major source of sulfur gases. The observed soil and canopy emission fluxes are similar to those measured in temperate regions. The concentrations of SO (sub 2) and sulfate aerosol in the wet season atmosphere were similar to dry season values. The sulfate concentration in rainwater, on the other hand, was lower by about a factor of 5 during the wet season. Due to the higher precipitation rate, however, the wet deposition flux of sulfate was not significantly different between the seasons. The measured fluxes and concentrations of DMS, H (sub 2) S, and SO (sub 2) were consistent with a model describing transport and chemistry of these sulfur species in the boundary layer. The concentrations of aerosol and the sulfate deposition rate, on the other hand, could only be explained by import of significant amounts of marine and anthropogenic sulfate aerosol into the Amazon Basin.

Wet season aerosol concentrations and composition are variable in contrast to the remarkably uniform distribution and composition of the predominantly biogenic aerosol that we observed during the 1985 dry season. Four distinct intervals of enhanced aerosol concentration coincided with 3- to 5-day periods of extensive rainfall over central Amazonia. It is hypothesized that a major source of aerosols to the basin was the direct input of northern hemispheric air laden with variable mixtures of Saharan dust, marine aerosol, and possibly biomass combustion products. The enhanced aerosol concentrations over Amazonia were reduced in 1-3 days to 5-10% of their peak levels by large-scale changes in the circulation field with subsequent decoupling from the source region, frequent precipitation, and intermixing of northern and southern hemispheric air masses. The intrusion of northern hemispheric air into the Amazon Basin is linked to the establishment and persistence of the West African Subtropical High (WASH) in a limited region over west Africa. Marine aerosols may be intermixed with the soil dust during transit across the Atlantic or within the sea breeze regime along the northeast coast of South America. It is proposed that a principal source of NO (sub 3) (super -) and SO (sub 4) (super 2-) associated with the dust is biomass burning south of the Sahara in western Africa.

The technique has several advantages over other approaches in that it requires only relative calibration accuracy, is less susceptible to instrument error, and does not use directly a prior information. Results indicate significant horizontal variability of precipitable water at the mesoscale. Precipitable water gradients of 6 mm per 10 km are not uncommon. The results verify well against special rawinsonde measurements and the ensuing cloud field development. While only applied to these specialized aircraft data so far, the technique could be applied to Advanced Very High Resolution Radiometer and VISSR Atmospheric Sounder data.

Wet Season AN - 19075574; 9102838 AB - The gas phase concentrations of formic (HCOOH), acetic (CH3COOH) , and pyruvic (CH3C(O)COOH) acids in the forestry canopy, boundary layer, and free troposphere over the central Amazon Basin during the April-May segment of the 1987 wet season have been determined. At 150-m altitude in the boundary layer the daytime average concentrations were 430 +/-225, 340 +/-155, and 25 +/-15 ppt for HCOOH, CH3COOH, and CH3C(O)COOH, respectively. These values were five-fold lower than those observed in the 1985 dry season. Concentrations measured near the canopy top were not significantly different from boundary layer values (P = 0.10), while concentrations in the lower canopy were significantly less. Concentrations in the free troposphere (5 km) were lower than in the boundary layer and averaged 170 +/-40 , 210 +/-40, and 15 +/-15 ppt for HCOOH, CH3COOH, and CH3C(O)COOH, respectively. Five-fold enhancements of CH3C(O)COOH concentrations were observed in convective outflows at 5 to 6 km altitudes. Aerosol carboxylate concentrations were usually below the detection limits of 5-10 ppt. Preliminary branch enclosure measurements indicated significant direct emission of carboxylic acids by vegetation. A one dimensional photochemical model for the canopy and the boundary level was used to examine the contributions from various sources to the carboxylic acid budgets. Model results indicate that direct emissions from vegetation can account for most of the concentrations observed in the canopy. These emissions peak during the daytime hours. Direct emissions from vegetation can account for only a small fraction of the observed carboxylic acid concentrations in the boundary layer, suggesting a large contribution from atmospheric sources. appear to be too slow to explain the observed concentrations. Other atmospheric reactions, so far unidentified , could make a major contribution to the carboxylic acid budgets.

The model has a horizontal resolution of 4 x 5 degrees, but the runoff from each grid box within a particular river ' s drainage basin was summed on a resolution of 2 x 2.5 degrees to obtain the runoff at the river mouth. The mean annual runoff was calculated and compared with observations for 33 of the world 's largest rivers. For about half of the rivers with annual runoff in excess of 200 cu km, the model runoff is within about 20% of the observed value. The model overpredicts the runoff for rivers with less than 200 cu km/yr. Some of the inaccuracy in the runoff predictions occurs because of poor model precipitation fields, but the model 's parameterizations of groundwater storage and evapotranspiration are also suspect. New parameterizations, including the effects of both soil type and vegetation, should be investigated. In addition to being a good diagnostic for atmospheric modelers, the runoff that may occur during future climate changes can also be studied with these models.

The sediment, collected from saline ponds, was covered by a microbial mat that had high oxygen consumption rate and well-defined surface structure. Diffusion through the DBL constituted an important rate limitation to the oxygen uptake of the sediment. The mean effective DBL thickness decreased from 0.59 to 0.16 mm as the flow velocity of the overlying water was increased from 0.3 to 7.7 cm s super(-1)(measured 1 cm above the mat). The oxygen uptake rate concurrently increased from 3.9 to 9.4 nmol cm super(-2) min super(-1). The effects of surface roughness and topography on the thickness and distribution of the DBL were studied by three-dimensional mapping of the sediment-water interface and the upper DBL boundary at 0.1-mm spatial resolution. The DBL boundary followed mat structures that had characteristic dimensions >1/2 DBL thickness but the DBL had a dampened relief relative to the mat. The effective surface area of the sediment-water interface and of the upper DBL boundary were 31 and 14% larger, respectively, than a flat plane. Surface topography thereby increased the oxygen flux across the sediment-water interface by 49% relative to a one-dimensional diffusion flux calculated from the vertical oxygen microgradients.

AN - 36404588; 2799 AB - PURPOSE: Construction and operation of test facilities and testing the Advanced Solid Rocket Motor (ASRM), which will replace the motors currently used to launch the Space Shuttle, are proposed. The project site would be located at the John C. Stennis Space Center in Hancock County, Mississippi. The Space Center is located within 12 miles of the Gulf Coast and includes a NASA fee ownership area and an acoustical buffer zone. The fee area, where all NASA-approved institutional and industrial development takes place, occupies approximately 22 square miles. The acoustical buffer zone consists of 200 square miles extending outward 5 miles from the fee area perimeter. The ASRM project facilities would be located in the eastern portion of the fee area. Facilities to be constructed would include a lateral access road, a construction access road, an engineering operations building, a test control center, an equipment storage facility, a barge/dock facility on the existing canal, a test stand, a heavy duty transporter road to move the ASRM from the barge dock to the test stand, a deflection ramp, and a catch basin to collect stormwater runoff. A fire safety zone would be cleared around the test stand. Project operation may include testing up to four motors per year. Construction is scheduled to begin in late 1990, with initial testing scheduled in mid-1993. The test stand location is approximately 6.5 miles from the nearest community outside the Stennis Space Center and approximately 2.0 miles from most of the space center's workforce. Each test would last approximately two minutes and would emit combustion products that include aluminum oxide, hydrogen chloride gas, water vapor, carbon dioxide, aluminum chloride, and other constituents. Hot rocket exhaust would extend out horizontally from the test stand before the exhaust would lose energy and begin to rise to an altitude of more than 10,000 feet at the plume's centerline. POSITIVE IMPACTS: Testing of the ASRMs would greatly improve their reliability, flight safety, and performance. Federal expenditures on the Space Shuttle would be reduced, and privatization of the program would be encouraged. Employment associated with the development and operation of ASRM facilities would provide a boost to local economies. Minimum possible impacts to wetlands would result, and where impacts cannot be avoided, mitigation would be provided to return them to their natural state. Potential exposure to exhaust products should not cause any adverse effects on humans. NEGATIVE IMPACTS: Small amounts of wetlands could be filled and wildlife habitat displaced. Test firing the motors and disposing of waste propellant by burning would release pollutants into the ambient atmosphere; surface water, vegetation, and wildlife in the safety clear zone would be minimally affected by these localized air pollutants. Areas adjacent to the test sites would be exposed to high noise levels during test periods, which would occur two to four times per year.

Growth can occur without photosynthesis. AN - 80416018; 11538275 AB - Cell expansion in dicotyledonous leaves is strongly stimulated by bright white light (WL), at least in part as a result of light-induced acidification of the cell walls. It has been proposed that photosynthetic reactions are required for light-stimulated transport processes across plasma membranes of leaf cells, including proton excretion. The involvement of photosynthesis in growth and wall acidification of primary leaves of bean has been tested by inhibiting photosynthesis in two ways: by reducing chlorophyll content of intact plants with tentoxin (TX) and by treating leaf discs with 3-(3,4-dichlorophenyl)-1,1-dimethylurea (DCMU). Exposure to bright WL stimulated growth of intact leaves of TX-treated plants. Discs excised from green as well as from TX-or DCMU-treated leaves also responded by growing faster in WL, as long as exogenous sucrose was supplied to the photosynthetically inhibited tissues. The WL caused acidification of the epidermal surface of intact TX-leaves, but acidification of the incubation medium by mesophyll cells only occurred when photosynthesis was not inhibited. It is concluded that light-stimulated cell enlargement of bean leaves, and the necessary acidification of epidermal cell walls, are mediated by a pigment other than chlorophyll. Light-induced proton excretion by mesophyll cells, on the other hand, may require both a photosynthetic product (or exogenous sugars) and a non-photosynthetic light effect.

Dynamics of the model are based upon a force balance approach that incorporates variable width of a flowband, bedslope, radius of curvature, and center of outflow location. Drumlin axes along five hydrostatic isograms were projected northward. Points of axes convergence define the center of outflow in the eastern Ontario Basin. Flowlines along the axial trace of the major Seneca and Cayuga Troughs and bordering interfluves were constructed southward to the Valley Heads Moraine System. Calculation of flowline geometry for any assumed basal shear stress requires neither information on ice temperature nor the flow law of ice. Ice thicknesses for each flow line were calculated for tau (sub b) values of .5, 1.0, and 1.5 bar. Ice thicknesses at 1 bar range from a minimum of 1,932 m for the Seneca Trough flowline to a maximum of 2,093 m at the Keuka-Seneca interfluve flowline. Raising or lowering tau (sub b) by .5 bar results in maximum thickness differences of +21% and -26%, respectively. Simulating ice recession, a series of ice-marginal, terminal positions were plotted for a basal shear stress of 1 bar. These predicted terminal positions agree well with locations of mapped moraine deposits. These probable values of basal shear stress support the presence of glacial flow representative of internal deformation rather than basal sliding. Although recent interpretations of the formation of the Finger Lakes focus on ice streams facilitated by large volumes of subglacial meltwater, our evidence discounts the presence of ice streams and supports the existence of outlet glaciers in the troughs of the Finger Lakes.

Biofacies and lithofacies analyses indicate progressive banktop submergence and paleoenvironmental response during Holocene sea-level rise. Stable-isotope values shift markedly from -27.7ppm within the 7900 B.P. paleosol at the base of the core to -11.1ppm at the present-day sediment-water interface. An abrupt excursion toward heavy-isotope values records the first establishment of Thalassia seagrass upon open-marine flooding. A multitracer approach, combining biofacies, lithofacies, and stable-isotope analysis of TOC confirms that the dramatic +17ppm shift observed in Delta (super 13) C was a direct result of sea-level rise and associated environmental changes over the banktop; there is little evidence of spurious diagenetic overprint. Stable-isotope analyses of organic carbon may enhance the reconstruction of carbonate sequences by revealing a distinctive geochemical signature of banktop flooding, including the onset of growth of otherwise unpreservable Thalassia seagrass.

The variation of albedo and emissivity with wavelength is caused by the spectral variation of the absorption coefficient of solid CO (sub 2) . The most important variables controlling the radiative properties are grain size and contamination by dust or water. Solar zenith angle and snowpack thickness are of less importance. The observation that red albedo is higher than blue albedo in the Martian south polar cap indicates that the snow is contaminated with red dust. The interband absorption coefficient of CO (sub 2) ice in the thermal infrared is 2-3 orders of magnitude smaller than that of H (sub 2) O ice, due to the absence of hydrogen bonding in CO (sub 2) . This allows CO (sub 2) snow emissivity to be sensitive to grain size, emission angle, and impurities, in contrast to water snow which is nearly a blackbody under all conditions. The emissivity of CO (sub 2) snow varies substantially with wavelength, so energy budget modeling should be done in spectral detail. The addition of a thin layer of water frost over CO (sub 2) snow dramatically raises the thermal emissivity but causes little change to the spectrally averaged albedo unless the underlying CO (sub 2) snow is dirty. Remote sensing of CO (sub 2) grain size, H (sub 2) O content, and dust content may be possible. However, the design of a remote-sensing strategy awaits more accurate laboratory determination of the optical constants of CO (sub 2) ice. Copyright 1990 by the American Geophysical Union.

Spectra were obtained for several large spots on Mars, whose ground temperatures and air masses through the Martian atmosphere differed significantly. These data were taken at two times during the flight. By taking the ratio of the spectral flux from one spot to that of a second spot, we obtained results that were independent of uncertainties in the instrument's spectral response and the transmission of the Earth's atmosphere. These data, as well as spectral fluxes of single spots based using the star alpha Tau as a calibration standard, show a number of emission and absorption features. They are present in sets of spectra taken at two different times. Some of the absorption features are due to gaseous CO (sub 2) in the Martian atmosphere. The remainder of the absorption and emission features are due to minerals present in the airborne dust and on the surface. Comparison of the strength of features seen at similar times, but with three different air masses and ground temperatures, suggests that the emission features arise primarily from surface emissivity spectral variations and that the absorption features arise from components of the atmosphere. Based on comparisons of the observed features with laboratory data for a broad ensemble of minerals, spectra of other solar system bodies, and relevant compositional information about Mars, we have made the following tentative identifications of the observed features. Emission features at 7.8 and 9.7 mu m are attributed to surface silicates; an emission feature at 6.1 mu m is attributed to a molecular water component of the surface material; an absorption band at 8.7 mu m as well as possibly one at 9.8 mu m is ascribed to sulfate or bisulfate anions, probably located in a distorted crystalline site; and an absorption band at 6.7 mu m is attributed to carbonate or bicarbonate anions located in a distorted crystalline site, although we cannot totally rule out a nitrate origin for this feature. We have simulated these spectra with radiative transfer programs for the atmosphere and surface. These simulations indicate that the sulfate- and carbonate-bearing minerals are contained in the same particles of the airborne dust as the dominant silicate minerals, that the dust optical depth was about 0.6 at a reference wavelength of 0.3 mu m over the area of the observed spots, and that sulfates and carbonates constitute about 10-15% and 1-3% by volume of the airborne dust, respectively. These results imply that minerals formed by weathering processes represent major reservoirs of volatile species on current Mars. Copyright 1990 by the American Geophysical Union.

Using morphometric data for venusian domes in Aubele and Slyuta (in press), as well as our own measurements of representative dome volumes and areas from Tethus Regio, we demonstrate that the characteristic aspect ratios and flank slopes of these features are consistent with a subclass of low Icelandic lava-shield volcanoes (LILS ). LILS are slightly convex in cross-section with typical flank slopes of approximately 3 degrees . Plausible lavashield-production rates for the venusian plains suggest formation of approximately 53 million shields over the past 0.25 Ga. The cumulative global volume of lava that would be associated with this predicted number of lava shields is only a factor of 3-4 times that of a single oceanic composite shield volcano such as Mauna Loa. The global volume of all venusian lava shields in the 0.5-20-km size range would only contribute a meter of resurfacing over geologically significant time scales. Thus, venusian analogs to LILS may represent the most abundant landform on the globally dominant plains of Venus, but would be insignificant with regard to the global volume of lava extruded. As in Iceland, associated lavas from fissure eruptions probably dominate plains volcanism and should be evident on the higher resolution Magellan radar images.

Reflectivity spectra of <20 mu m size separates resemble spectra for Martian bright regions, and reflectivity spectra of coarser size separates have some spectral characteristics in common with spectra for Martian dark regions. The bulk soil is magnetic with a saturation magnetization of 0.98 A m (super 2) /kg of sample ( approximately 10 A m (super 2) /kg of Fe) at 296 K. Petrographic observations show that the soil contains separate populations of black and orange tephra particles which are relatively unaltered fragments of tachylite (merocrystalline basalt) and extensively weathered (palagonitized) fragments of sideromelane (clear, brown basalt glass), respectively. Although both types of particles contain plagioclase and olivine microphenocrysts, their iron-oxide mineralogies are substantially different, as documented by Mossbauer and static-magnetic measurements. A strongly magnetic, opaque iron-oxide (titanomagnetite) is associated with black particles and is responsible for the magnetic nature of the soil. A relatively weakly magnetic, superparamagnetic ferric-oxide and minor hematite are associated with orange particles and are responsible for the color. The more highly weathered state (higher state of oxidation) of orange particles is a consequence of the faster weathering (palagonitization) rate for their sideromelane precursors than for tachylite. Increasing state of oxidation, decreasing saturation magnetization, and increasing near-IR reflectivity with decreasing particle diameter of bulk soil are manifestations of the increasing proportions of palagonitic material as particle diameter decreases.

One-dimensional (vertical, static atmosphere) and two-dimensional (latitude-height, steady state circulation) simulations carried out with an aerosol transport-microphysical model indicate that atmospheric motions play a significant role in the observed decay of global dust storms. Spacecraft observations (Mariner 9, Viking) of the 1971 and the two 1977 planet-encircling dust storms have provided suggestions about some characterisrics of storm decay. Specifically, the dust particle size distribution is inferred to have remained essentially unchanged for particles with radii between 1 and 10 mu m during decay of the 1971 storm, and surface visible opacity declined quasi-exponentially with time in northern mid-latitudes during the decay of the two 1977 storms. The results from this investigation indicate that two- and three-dimensional dynamical processes play a significant role in the observed decay features of Martian global dust storms. The most important processes are the lofting of dust by vertical motions in the dust source region of the southern hemisphere subtropics and a continuing advective resupply of atmospheric dust into the dust sink regions of the northern hemisphere. Our work has implications for Viking data analyses and future Mars observer observations and requires that the particle size distribution be treated as a time and latitude dependent quantity.

Using the measured mass influx at Earth and estimates of the Mars/Earth flux ratio, we estimate the continuous, planet-wide meteoritic mass influx on Mars to be between 2700 and 59,000 t/yr. If distributed uniformly into a soil with a mean planetary production rate of 1 m/b.y., consistent with radar estimates of the soil depth overlaying a bouldered terrain in the Tharsis region [Christensen, 1986], our estimated mass influx would produce a meteoritic concentration in the Mars soil ranging from 2 to 29% by mass. Analysis of the Viking X ray fluorescence data indicates that the Mars soil composition is inconsistent with typical basaltic rock fragments but can be fit by a mixture of 60% basaltic rock fragments and 40% meteoritic material [Clark and Baird, 1979]. The meteoritic influx we calculate is sufficient to provide most or all of the material required by the Clark and Baird [1979] model. Particles in the mass range from 10 (super -7) to 10 (super -3) g, about 60-200 mu m in diameter, contribute 80% of the total mass flux of meteoritic material in the 10 (super -13) to 10 (super 6) g mass range at Earth [Hughes, 1978]. On Earth atmospheric entry all but the smallest particles (generally < or = 50 mu m in diameter) in the 10 (super -7) to 10 (super -3) g mass range are heated sufficiently to melt or vaporize. Mars, because of its lower escape velocity and larger atmospheric scale height, is a much more favorable site for unmelted survival of micrometeorites on atmospheric deceleration. We calculate that a significant fraction of particles throughout the 60-1200 mu m diameter range will survive Mars atmospheric entry unmelted. Thus returned Mars soils may offer a resource for sampling micrometeorites in a size range which is not collectable in unaltered form at Earth. Copyright 1990 by the American Geophysical Union.

The spectra show weak absorption features due to Martian atmospheric carbon monoxide and a surface mineral. Both CO and the mineral absorptions are composed of overlapping narrow features, but in many locations, such as Hellas, Chryse, Eden, and Moab, the mineral absorptions are quite strong, at least 3 times stronger than at the most absorbing wavelengths of CO near 2.33 mu m. Therefore CO complicates the analysis of the surface mineral but does not always overwhelm its signature. Model removal of the Martian atmospheric CO has been performed, and the remaining absorption bands are identified as scapolite. Relatively strong absorptions that match bands in the spectrum of scapolite and have little or no CO absorption interference are seen near 2.41, 2.39, and 2.29 mu m. Absorption also occurs at the scapolite bands at 2.36 and 2.33 mu m, but the analysis is complicated by uncertainty in the atmospheric CO removal at these wavelengths. Weaker scapolite bands are seen at 2.44 and 2.23 mu m where there is virtually no atmospheric interference. The scapolite bands observed on Mars are due to HCO (sub 3) (super -) and HSO (sub 4) (super -) ions in the scapolite structure. The bicarbonate and bisulfate contents appear to vary with location: the scapolite in Hellas is more bisulfate-rich relative to that in the Chryse/Moab/Eden area. Other locations contain little (Arabia, Syrtis Major, Hellespontica, and Isidis) or no scapolite (e.g., Margaritifer, Ausonia, and Erythraeum). The calculated abundances are unconstrained because the amounts of HCO (sub 3) (super -) and HSO (sub 4) (super -) in the Martian scapolites as well as their grain sizes are not known. If the scapolites contain about 3 wt % of each, near the maximum possible, the scapolite abundances probably range from about 5 wt % scapolite at Eden and Hellas; 3-5% at Chryse, Moab, and Oxia Palus; 2-3% at Arabia, Syrtis Major, and Isidis; to less than 2% at Hellespontica, Syrtis Minor, and Margaritifer, assuming a relatively large grain size of 50-100 mu m. If the characteristic grain sizes are smaller or the HCO (sub 3) (super -) and HSO (sub 4) (super -) contents are lower, the scapolite abundances required to match the observed band depths would be higher. The mineral bands are apparent in many of the Mars spectra measured, so it appears to be widely but not uniformly distributed. The newly observed fine structure also varies greatly in both depth and spectral detail with location on Mars. Thus there appears to be regional variations in composition. The mineral phases appear to reflect local or regional geology and are not primarily contained in the homogeneous, globally redistributed aeolian dust. Higher spectral resolution Martian spectra in the 2.3-mu m region as well as at 3.9 mu m are needed to confirm the scapolite identification and to constrain its abundance.

To assess the expected improvement of the gravity field, we have conducted an error analysis based upon the mission plan for the Mars Observer radio tracking data from the Deep Space Network. Our results indicate that it should be possible to obtain a high-resolution model (spherical harmonics complete to degree and order 50 corresponding to a 200-km horizontal resolution) for the gravitational field of the planet. This model, in combination with topography from MO altimetry, should provide for an improved determination of the broad scale density structure and stress state of the Martian crust and upper mantle. The mathematical model for the error analysis is based on the representation of doppler tracking data as a function of the Martian gravity field in spherical harmonics, solar radiation pressure, atmospheric drag, angular momentum desaturation residual acceleration (AMDRA) effects, tracking station biases, and the MO orbit parameters. Two approaches are employed. In the first case, the error covariance matrix of the gravity model is estimated including the effects from all the nongravitational parameters (noise-only case). In the second case, the gravity recovery error is computed as above but includes unmodelled systematic effects from atmospheric drag, AMDRA, and solar radiation pressure (biased case). The error spectrum of gravity shows an order of magnitude of improvement over current knowledge based on doppler data precision from a single station of 0.3 mm s (super -1) noise for 1-min integration intervals during three 60-day periods. This first approach of noise only yielded an estimated total accuracy (omission plus commission) for a 200 km block size of 5.4 m for geoid undulations and 31 mGal for gravity anomalies. For the second case, corresponding to the unmodelled systematic effects, an additional error of 5% in the above statistics was obtained. Although the degradation in the accuracy of the mean gravity anomalies and mean geoid undulations is not very pronounced, significant degradation in the recovery of the harmonic coefficients was observed due to the unmodelled systematic nongravitational effects (mainly atmospheric drag). A worst result occurred for an individual 60-day period, corresponding to maximum atmospheric drag, which gave significant degradation for the low-degree terms out through degree 20. However, the overall accuracy for the combined solution of the three 60-day periods for the second case of systematic effects gave only a small difference from the noise-only solution. The results suggest that the spacecraft orbit could possibly be raised in altitude without significant loss of gravitational signal, because the atmospheric drag is the dominant error source. A change in altitude could also alleviate the large effects seen in the spectrum of the satellite resonant orders. A conservative error estimate for the gravity recovery, corresponding to the complete mapping period, was made based upon a simplified approach of scaling systematic and random effects so as to correspond to each orbit orientation period. These contributions of each orbit orientation were combined throughout the entire mapping mission to obtain the overall accuracy estimate of the gravity field.

We compile and summarize the evidence for Martian impact basins and suggest eight new examples. Multiring basins on Mars define three morphologic subclasses with increasing basin size. Basins having diameters 300 3600 km) have extremely shallow topographic profiles and numerous concentric structures expressed as scarps, massifs, and channels. Radial and concentric structures analogous to those associated with Orientale are not apparent for basins of Argyre size or larger. These variations in basin morphology and structure may be associated with mechanical interactions between basin-forming impacts, relatively thin, weak lithosphere, and, for the largest impacts, spherical target geometry. Multiring basins are recognized on all parts of Mars, including Tharsis, Elysium, and the northern lowlands. Much of the subsequent resurfacing of cratered terrain such as Lunae Planum ridged plains is associated spatially with multiring basins. Nucleation of long-lived volcanic complexes in Tharsis and Elysium was probably aided by early impact basins. The planetary terrain dichotomy was probably established during the period of heavy meteoritic bombardment, and subsequent processes in the northern plains region were not sufficiently vigorous to destroy or completely obscure the underlying multiring basin fabric. The revised population of multiring basins is consistent with the size frequency distribution of craters < 500 km in diameter on Mars. Basins having diameters approximately 500 < D < 1850 km are characterized by a cumulative frequency slope of -0.75 + or -0.16, whereas the larger basins define a slope of -1.7 + or - 0.45. This change in slope occurs over the same diameter range as the significant change from Orientale type basin morphology at smaller diameters to Argyre and Chryse type basin morphology. The population of craters and basins on Mars confirms that the relative crater densities on the terrestrial planets due to heavy bombardment are comparable, perhaps suggesting a common source for the impacting objects.

Grabens and normal faults within the sheeted dike complex and the extrusive sequence of the Troodos ophiolite resemble those of oceanic spreading centers. Diverse intrusive and tectonic contact relationships between the sheeted dike complex and the underlying plutonic sequence indicate multiple and episodic intrusion of magma and along- and across-strike variation in volcanic and tectonic activity during development of oceanic crust. Coupled with the existence of the Arakapas transform fault to the south, these structural and intrusive relationships suggest origin at an intersection between a spreading center and a transform fault. The arclike chemistry of sheeted dikes and related extrusive rocks and the inferred highly depleted and hydrous nature of the mantle source of the late stage intrusive and extrusive rocks argue, however, for generation of part of the ophiolite within a subduction zone environment. Regional reconstructions suggest that the Mesozoic Neotethys may have evolved as a marginal basin both to the Afro-Arabian continent and the Paleotethyan ocean over an active or recently active south dipping subduction zone. The Troodos ophiolite and other eastern Mediterranean ophiolites, whose magma compositions were affected by the subducted Paleotethyan slab, may have formed along east-west trending spreading centers separated by north-south trending transform faults within this marginal basin. A rapid change in relative plate motion in late Cretaceous time between Eurasia and Afro-Arabia created a regional compressive regime that may have resulted in plate boundary reorganizations within the Neotethyan realm and in initiation of north dipping subduction zone(s) beneath the Troodos and other ophiolites in the region. The apparent forearc setting of the Troodos ophiolite is a consequence of this intraoceanic displacement after its formation and thus is unrelated to its generation.

SiB calculates the land surface fluxes of heat, moisture and momentum, as well as the near-surface fluxes of shortwave and longwave radiation with an explicit parameterization of the interactions among atmosphere, vegetation, and soil processes. Ensemble sets of four July and four January simulations were made with the GLA GCM to evaluate the influence of SiB. Each set contained two runs: one with and one without SiB in the GCM. After allowing an initial adjustment period of about 16 days, the last 31 days of each integration were taken to represent the desired simulation. The results of the SiB vs. no-SiB comparison show that SiB simulates much lower evapotranspiration rates over land and generates significantly different values of surface fluxes for both vegetated and bare soil regions. These differences in the surface fluxes are accompanied by large and statistically significant changes in the simulated rainfall, particularly in the tropics and the summer hemisphere. An analysis of the monthly mean diurnal cycle of surface fluxes shows that both the surface fluxes and rainfall values for the SiB-GCM are realistic in different regions: densely vegetated, sparsely vegetated, and bare soil (including dry deserts). Despite some shortcomings of the SiB-GCM simulations, such as insufficient latitudinal displacement of the ITCZ in both the summer and winter simulations, it is evident that the SiB provides a better estimate of the surface fluxes on the whole, leading to improvements of the simulated circulation and rainfall climatology of the Earth.

A sun photometer network in Mali and Niger, Africa, was established in 1984 to measure the temporal and spatial variability of aerosols and water vapor. A new technique was applied to the master calibration instrument based on a Mauna Loa Langley calibration data set. Measurements obtained with the calibrated instrument for 14 days in July 1987 at Goddard Space Flight Center (Greenbelt, MD), retrieved the vertical column precipitable water to within an average of 0.28 cm of the radiosonde measured values under a 2- 5 cm precipitable water range and a large range of aerosol optical thicknesses. The calibration was transferred to the sun photometers in the Sahel via intercalibration. Precipitable water retrieved for the Sahelian sites show close agreement with the sparse radiosonde data available and is consistent with published data. The spatial variability of the precipitable water was found to be significantly lower than the aerosol optical depth spatial variability, and there is no correlation between the magnitude of precipitable water and aerosol optical depth. The network shows a dry season monthly average precipitable water value of 1-2 cm and a wet season range of 3.5-4.5 cm.

AN - 80414295; 11538074 AB - It has long been speculated that Earth accreted prebiotic organic molecules important for the origins of life from impacts of carbonaceous asteroids and comets during the period of heavy bombardment 4.5 x 10(9) to 3.8 x 10(9) years ago. A comprehensive treatment of comet-asteroid interaction with the atmosphere, surface impact, and resulting organic pyrolysis demonstrates that organics will not survive impacts at velocities greater than about 10 kilometers per second and that even comets and asteroids as small as 100 meters in radius cannot be aerobraked to below this velocity in 1-bar atmospheres. However, for plausible dense (10-bar carbon dioxide) early atmospheres, we find that 4.5 x 10(9) years ago Earth was accreting intact cometary organics at a rate of at least approximately 10(6) to 10(7) kilograms per year, a flux that thereafter declined with a half-life of approximately 10(8) years. These results may be put in context by comparison with terrestrial oceanic and total biomasses, approximately 3 x 10(12) kilograms and approximately 6 x 10(14) kilograms, respectively.

AN - 80414125; 11537609 AB - A future goal of the U.S. space program is a commitment to the manned exploration and habitation of Mars. An important consideration of such missions is the exposure of crew members to the damaging effects of ionizing radiation from high-energy galactic cosmic ray fluxes and solar proton flares. The crew will encounter the most harmful radiation environment in transit to Mars from which they must be adequately protected. However, once on the planet's surface, the Martian environment should provide a significant amount of protection from free-space radiative fluxes. In current Mars scenario descriptions, the crew flight time to Mars is estimated to be anywhere from 7 months to over a year each way, with stay times on the surface ranging from 20 days to 2 years. To maintain dose levels below established astronaut limits, dose estimates need to be determined for the entire mission length. With extended crew durations on the surface anticipated, the characterization of the Mars radiation environment is important in assessing all radiation protection requirements. This synopsis focuses on the probable doses incurred by surface inhabitants from the transport of galactic cosmic rays and solar protons through the Mars atmosphere.

From repeated VLBI occupations of these sites since 1983, the pre-earthquake rates of deformation have been determined with respect to a North American reference frame with 1sigma formal standard errors of approximately 1 mm/yr. The VLBI measurements immediately following the earthquake showed that the Fort Ord site was displaced 49 + or - 4 mm at an azimuth of 11 + or - 4 degrees and that the Presidio site was displaced 12 + or - 5 mm at an azimuth of 148 + or - 13 degrees . No anomalous change was detected at Point Reyes with 1sigma uncertainty of 4 mm. The estimated displacements at Ford Ord and the Presidio are consistent with the static displacements predicted on the basis of a coseismic slip model in which slip on the southern segment is shallower than slip on the more northern segment of the fault rupture. We also give the Cartesian positions at epoch 1990.0 of a set of VLBI fiducial stations and the three mobile sites in the vicinity of the earthquake. Copyright 1990 by the American Geophysical Union.

Nitrous oxide is soluble and can accumulate in soil solution when gaseous diffusion is restricted. The importance of N losses via degassing of nitrous oxide from groundwater entering surface streams is unknown. Measurements of nitrous oxide in soil solution at an 8.9 ha watershed at the USDA Forest Service Coweeta Hydrologic Laboratory, North Carolina, revealed patterns of seasonal and spatial variation that were consistent with ecosystem regulation of denitrification. The highest concentrations were observed in the riparian zone in May, when soil nitrate, temperature, and moisture were conducive for denitrification. At each of the other sample dates and sites, at least one of these factors appeared to prevent significant nitrous oxide accumulation in soil solution. Extrapolation of the highest observed nitrous oxide concentrations to an annual basis corresponded to a loss of only 56 g N/ha/yr. Denitrification in the riparian zone may be an important fate of N in this hardwood forest, but nitrous oxide in soil solution does not appear to be a significant pathway of N loss. This site might be expected to produce nitrous oxide at higher rates than most hardwood forests, but extrapolation of the highest calculated losses from soil solution over the global area occupied by hardwood forest indicates that this source of nitrous oxide is insignificant for global atmospheric budgets.

AN - 36405734; 2719 AB - PURPOSE: Implementation of the Ulysses space flight mission to observe the polar regions of the Sun is proposed. More specifically, the proposed action would involve completing the preparation and operation of the Ulysses spacecraft, including its planned launch on the Space Transport System (STS) Shuttle in October 1990 or in the backup opportunity in November 1991. The alternative is to cancel further work on the mission. To achieve an orbit over the poles of the Sun, the spacecraft must travel to Jupiter and use that planet's huge gravitational pull to propel the spacecraft out of the planetary plane and into a polar orbit of the Sun. The Tier 1 environmental impact statement, prepared by the National Aeronautics and Space Administration (NASA) in 1988, included a delay alternative that considered the Titan IV launch vehicle as an alternative booster stage for launch in 1991 or later; however, in November 1988, the U.S. Air Force, which procures the Titan IV, notified NASA that it could not provide a Titan IV vehicle for the 1991 launch opportunity due to high priority Department of Defense requirements. Subsequently, NASA was notified that a Titan IV could not be available until 1995. Even if a Titan were available, a minimum of three years would be required to implement mission-specific modifications to the basic Titan IV launch configuration after a decision was made to use the Titan IV; therefore, insufficient time would be available to use a Titan IV vehicle in November 1991. Thus, the Titan IV launch vehicle is no longer a feasible alternative to the STS/Inertial Upper Stage (IUS) /Payload Assist Module-Special (PAM-S) for the November 1991 launch opportunity. Consequently, NASA terminated all mission planning for the Titan IV as a backup launch vehicle. POSITIVE IMPACTS: The Ulysses mission would support NASA's Solar System Exploration Program as well as the agency's Space Physics Program. The mission would contribute to NASA's goals of characterizing the solar system's interplanetary medium and describing the high latitude characteristic of the solar wind and how it helps control the geospace environment and affects solar processes on Earth. The major scientific objectives of the Ulysses mission would include characterization of the inner heliosphere as a function of heliographic latitude and characterization of particles and fields from the ecliptic to the Sun's poles. NEGATIVE IMPACTS: The only expected environmental impacts of the proposed action would be those associated with normal launch vehicle operation and are treated in published environmental impact statements (EISs) on the Shuttle (NASA, 1978) and the Kennedy Space Center (NASA, 1979) and in the Kennedy Space Center Environmental Resources Document (NASA, 1986), the Galileo and Ulysses Mission Tier 1 EIS (NASA, 1988), and the Galileo Tier 2 EIS (NASA, 1989). The only impacts would include temporary stratospheric ozone effects and occasional sonic boom effects. In the event of an accident during launch or reentry of the spacecraft from Earth orbit, there would be potential adverse health and environmental effects associated with the possible release of plutonium dioxide from the spacecraft's Radioisotope Thermoelectric Generator; these impacts would include air and water degradation, local land area contamination, and impact damage.

AN - 79838709; 2356274 AB - An analytic solution for high-energy heavy ion transport assuming straight-ahead and velocity-conserving interactions with constant nuclear cross-reactions is given in terms of a Green's function. The series solution for the Green's function is rapidly convergent for most practical applications. The Green's function technique can be applied with equal success to laboratory beams as well as to galactic cosmic rays allowing laboratory validation of the resultant space shielding code.

The relatively low resolution of this instrument makes it ideal for obtaining a broad view of the ice sheets, while its wide swath allows coverage of areas beyond the reach of high-resolution imagers either currently in orbit or planned. The replacement of high-resolution imagery with AVHRR is not advocated, but rather, the two are viewed as highly complementary. Low-resolution imagery can be effectively used for the initial assessments of the regional dynamics of ice sheets and should be used as guides for choosing the location of more expensive, high-resolution imagery. High-resolution image data will continue to be used for detailed determination of surface velocity and stress fields, mapping, and a host of other applications. With so much of the antarctic continent still poorly mapped, it is likely that there will be more surprises of current and past ice flow resulting from future glaciological investigations. AVHRR imagery, and data from similar instruments such as the 600-m-resolution Defense Meteorological Satellite Program (DMSP) data, can play a significant role in uncovering many of these and should become a more familiar tool of the antarctic scientist.

The atmospheric model is used to simulate the climate of 18,000 years ago using Climate: Long-Range Investigation, Mapping, and Prediction data for the model's seasonally varying sea surface temperatures, ice coverage, and surface topography. The water transports are calculated for each ocean basin using the model's evaporation, precipitation, and runoff. For the present climate, the model's glacial ice sheets and the global water budget are near equilibrium. For the ice age the model does not maintain the glacial ice sheets at steady state but causes them to melt; therefore we reduced the runoff from melting ice to bring the global water budget into equilibrium. Recent studies have shown that salinity anomalies in the North Atlantic caused by changes in the freshwater transport could change the thermohaline circulation. For the present climate the evaporation exceeds the sum of precipitation and runoff in the Atlantic Ocean which leads to a higher mean salinity in the Atlantic than in the Pacific Ocean. The results suggest that this water budget reversed in the Atlantic during the last ice age. This conclusion, however, cannot be stated firmly because the model's global water budget was not in equilibrium for the ice age. The model's freshwater transports for the last ice age are compared with those for the present climate, and implications on changes in thermohaline circulation are discussed.

March sea ice limits were set equivalent to modern September limits, and all sea ice was removed in September. Sea ice coverage for other months varied between these two extremes. This climate sensitivity experiment makes predictions about mean northern hemisphere atmospheric conditions (including temperature, pressure, wind patterns, and precipitation) consistent with these boundary constraints. The major effects of reduced sea ice limits are observed in winter. They include large regional warming of the circum-Arctic region, northward migration of the Icelandic low pressure system, and strengthening of the Azores high. Changes in net heating over the North Atlantic Ocean suggest that increases in sea surface temperatures and salinities in this region would also accompany reductions in Arctic sea ice limits. In the wind field, a weakening of the polar easterlies and an intensification of cyclonic circulation over the Norwegian-Greenland Sea suggest that surface water exchange between the Atlantic and Arctic would increase when sea ice limits are reduced. However, zonally averaged changes in strength of the westerlies or upper level jet stream are minimal. The late Pliocene cooling of the North Atlantic Ocean and North American Arctic margin may have been linked in part to the development of perennial sea ice cover.

This global displacement field rearranges the Earth's mass distribution, causing the Earth's rotational properties and gravitational field to change. The size of these changes depends, in general, upon the size of the earthquake. The Macquarie Ridge earthquake of May 23, 1989 is considered to be the largest earthquake to have occurred since the 1977 Sumba and Tonga events. As such, the coseismic effect of this earthquake upon the Earth's length-of-day, polar motion, and low-degree harmonic coefficients of the gravitational field are computed. It is found that this earthquake should have caused the length-of-day to decrease by 0.06 mu sec, the position of the mean rotation pole to shift 0.11 milli-arcsec towards 323 degrees E longitude, and selected degree l = 2-5 gravitational field coefficients to change by about 1 part in 10 (super 13) . These changes are all smaller than can be detected by current observational techniques. However, changes of this size could perhaps be detected in the future with the implementation of proposed improvements to the techniques of monitoring the Earth's rotation, and (especially for the low-degree gravitational field coefficients) with the placement of GPS receivers onboard orbiting spacecraft.

A successful model climate matches the earth 's observed climate and responds realistically to changes in boundary conditions. A model representing a soil-atmosphere column in a GCM was developed for offline testing of GCM soil hydrology parameterizations. Repeating three representative GCM sensitivity experiments with this one-dimensional model demonstrates that, to first order, the model reproduces a GCM 's sensitivity to imposed changes in parameterization and therefore captures the essential physics of the GCM. The experiments also show that by allowing feedback between the soil and atmosphere, the model improves on offline tests that rely on prescribed precipitation, radiation, and other surface forcing.

Both indices show increasing drought for the US during the next century, with effects becoming apparent in the 1990s. At the present rate of greenhouse gas increase, model results suggest that severe drought (5% frequent today) will occur about 50% of the time by the 2050s. The results are driven by the large increases in evapotranspiration potential (Ep) associated with simulated climatic warming. Ep increases most where the temperature is highest. Atmospheric demand becomes greater than supply for most of the globe by the latter half of the next century. Large Ep changes can lead to soil moisture deficits and vegetation desiccation as implied by climate models. A lack of realistic surface models has led to drought intensity understatement. Goddard Institute for Space Studies general circulation model is responsible for this lack. Global precipitation can not keep pace with increased demand over land because the land surface warms more than the ocean surface. This effect, along with greater atmospheric opacity, reduces low level gradients and evaporation from the ocean. If the forecast temperature changes come to pass, these conclusions suggest that drought conditions will increase dramatically.

AN - 80414712; 11538181 AB - An area-mapping technique, designed to filter out synoptic perturbations of the Antarctic polar vortex such as distortion or displacement away from the pole, was applied to the Nimbus-7 TOMS (Total Ozone Mapping Spectrometer) data. This procedure reveals the detailed morphology of the temporal evolution of column O3. The results for the austral spring of 1987 suggest the existence of a relatively stable collar region enclosing an interior that is undergoing large variations. There is tentative evidence for quasi-periodic (15 to 20 days) O3 fluctuations in the collar and for upwelling of tropospheric air in late spring. A simplified photochemical model of O3 loss and the temporal evolution of the area-mapped polar O3 are used to constrain the chlorine monoxide (ClO) concentrations in the springtime Antarctic vortex. The concentrations required to account for the observed loss of O3 are higher than those previously reported by Anderson et al. but are comparable to their recently revised values. However, the O3 loss rates could be larger than deduced here because of underestimates of total O3 by TOMS near the terminator. This uncertainty, together with the uncertainties associated with measurements acquired during the Airborne Antarctic Ozone Experiment, suggests that in early spring, closer to the vortex center, there may be even larger ClO concentrations than have yet been detected.

AN - 50687792; 1990-035211 AB - Are the circular, highly deformed cryptoexplosion structures found on Earth, and the shock-metamorphic features they contain, astroblemes formed by meteorite impact, or are they formed by internal volcanic processes (cryptovolcanism)? Numerous studies have reinforced the view that shock-metamorphic features uniquely indicate shock P of approx 5 to > 50 GPa; no generally accepted shock-metamorphic features have been found in undoubted volcanic structures; no internal process has been shown to produce the required shock P.This therefore supports an impact origin for both cryptoexplosion structures and the K/T event. Future discoveries required to make the cryptovolcanic theory a respectable alternative include undisputed shock features such as shatter cones, shock lamellae, stishovite, and lechatelierite in a volcanic structure; high Ir contents (> 1 ppb) in volcanic ejecta layers; and a rigorous, testable theory for producing high shock P by internal processes.

It consists of three types of drag: Yarkovsky thermal, neutral particle, and charged particle. Yarkovsky thermal drag depends on the LAGEOS spin axis position. The spin axis in the decade since launch appears to have stayed near where the engineering telemetry data put it at apogee kickmotor separation: 22 degrees colatitude and 313 degrees east longitude. This result is based on fitting more than 11 years of along-track acceleration data to a thermal model. The Center for Space Research at the University of Texas has obtained a similar answer. For this position, Yarkovsky thermal drag accounts for about 70% of the observed drag. Neutral particle drag accounts for about 14% of the drag for a hydrogen number density of 5 X 10 (super 9) m (super -3) . Proton drag accounts for 12 per cent at a number density of 3 X 10 (super 9) m (super -3) and a temperature of 5000 K in the plasmasphere for a satellite potential of -1 V. Charged helium and oxygen give another 4%, so that charged particle drag totals 16%. All together the three types of drag account for all of the observed average drag. Hence there is closure: the particle environment at LAGEOS altitude, the drag models, and the observed drag are all consistent with each other. Less well understood are the fluctuations in LAGEOS's along-track acceleration when the orbit intersects the Earth's shadow. Copyright 1990 by the American Geophysical Union.

Np-Hm is characterized by particle diameters less than approximately 10 nm and has properties distinctly different from larger diameter hematite particles (bulk-Hm). Data were obtained for four series of powder samples which have different matrix properties and variable concentrations of np-Hm dispersed within discrete powder particles. The matrix materials are two size ranges of each of two compositions which have different internal scattering characteristics. Reflectivity data show that matrix properties have a large influence on the reflectivity spectra of pigmentary np-Hm. Samples with the same Fe (sub 2) O (sub 3) , content can have np-Hm absorption edges characterized by very different positions (color) and consequently, very different slope (R (sub 600) /R (sub 450) ) and curvature ((R (sub 600) )X(R (sub 450) )/(R (sub 550) ) (super 2) ) indices, where, for example, R (sub 600) is the reflectivity at 600 nm. Conversely, samples with equivalent absorption edges can have very different Fe (sub 2) O (sub 3) concentrations. For all samples, ranges of slope and curvature indices are 0.99-8.55 and 0.50-2.38, respectively. Although it may be possible to place limits, quantitative relationships between positions of ferric absorption edges and Fe (sub 2) O (sub 3) concentrations are unreliable without knowledge of matrix properties of the system under consideration. As an example, the curvature index is a measure of relative crystallinity (relative proportion of bulk-Hm) for a series of samples containing relatively increasing proportions of bulk-Hm over np-Hm only at constant Fe (sub 2) O (sub 3) concentration and constant matrix effects. In the absence of the stated conditions, variations in the curvature index can result from any combination of crystallinity, matrix effects, and pigment (hematite) concentration. It is possible to match the Fe (sub 2) O (sub 3) concentration, magnetic properties, and spectral data for Martian surface material with a laboratory mixture whose only ferric-bearing phase is hematite. What made this possible is a matrix material with suitable optical scattering properties and differences in optical and magnetic properties of np-Hm and bulk-Hm. Most of the hematite is present as strongly magnetic np-Hm, but some bulk-Hm is required to give a shallow approximately 860-nm band. Hematite is thus very likely present on Mars and may even be the dominant ferric mineralogy.

The optimal approx 20-m resolution, variable lighting and viewing geometry, and stereo capability of the Shuttle photography, provided an invaluable ancillary data set. At the resolution available, subtle glacial-morphological features such as valley and terminal moraines can confidently be identified, and these features have been used to determine the relative ages of volcanoes. Eight major volcanoes are postulated to be potentially active; most are large, dominantly andesitic, composite cones of <2500 m, some of which threaten nearby settlements. The active volcanic front is approx 200 km E of the Peru-Chile trench, and the volcanoes lie on a trench-parallel trend oblique to the E-W subduction. In comparison with the S part of the CVZ the scarcity of older volcanic edifices N of approx 17 degrees S suggests a more recent onset of volcanism N of this latitude. It seems that there are real differences between the volcanic evolution of different parts of the CVZ.

In the presence of attenuation, however, the reconstruction of the profile is possible with usual methods only if the rain rate is uniform or if the relationships between the radar measurables and the rain characteristics are well known. Even with a dual-wavelength radar, estimates of attenuation between adjacent range gates tend to be noisy. A class of methods that are based on a measure of path attenuation which is used to constrain the Hitschfeld-Bordan solution was investigated. Methods of this type have been investigated for lidar, radar, and combined radar- radiometer applications; their functions can be interpreted as allocating the attenuation in proportion to the strength of the measured reflectivity. Four estimates of rain rate were described and tested using data from a dual-wavelength airborne radar at 10 GHz and 35 GHz. When attenuation was significant, the estimates were generally more accurate than those without attenuation correction. This suggests that such methods can be used to extend the effective dynamic range of the radar to higher rain rates. Comparisons between the estimates also provide some diagnostic capability for the detection of radar calibration errors. Instabilities in the estimates can occur, however, in cases of low signal to noise ratios and in situations where partially melted hydrometeors contribute to the attenuation.

AN - 80414850; 11536463 AB - The efficiency of energy transfer in chlorosome antennas in the green sulfur bacteria Chlorobium vibrioforme and Chlorobium limicola was found to be highly sensitive to the redox potential of the suspension. Energy transfer efficiencies were measured by comparing the absorption spectrum of the bacteriochlorophyll c or d pigments in the chlorosome to the excitation spectrum for fluorescence arising from the chlorosome baseplate and membrane-bound antenna complexes. The efficiency of energy transfer approaches 100% at low redox potentials induced by addition of sodium dithionite or other strong reductants, and is lowered to 10-20% under aerobic conditions or after addition of a variety of membrane-permeable oxidizing agents. The redox effect on energy transfer is observed in whole cells, isolated membranes and purified chlorosomes, indicating that the modulation of energy transfer efficiency arises within the antenna complexes and is not directly mediated by the redox state of the reaction center. It is proposed that chlorosomes contain a component that acts as a highly quenching center in its oxidized state, but is an inefficient quencher when reduced by endogenous or exogenous reductants. This effect may be a control mechanism that prevents cellular damage resulting from reaction of oxygen with reduced low-potential electron acceptors found in the green sulfur bacteria. The redox modulation effect is not observed in the green gliding bacterium Chloroflexus aurantiacus, which contains chlorosomes but does not contain low-potential electron acceptors.

AN - 85193584; pmid-2304813 AB - Three experiments were designed to investigate naive observers' abilities at discriminating the rotational velocities of two simultaneously viewed objects. In Experiment 1, rotations could occur about parallel or orthogonal axes, with initial orientations in phase or out of phase, and (for parallel rotational axes) in the same or opposite direction. Differential thresholds were approximately 10%. In Experiment 2, stimulus objects differed in the number of faces revealed in rotation (three vs. four). Observers' response curves had no greater spread, but their PSEs (points of subjective equality) were shifted such that there was a partial compensation for faces revealed per unit time. In both Experiment 1 and Experiment 2, performance was consistent across rotational axis and directional conditions. In Experiment 3, the effect of object size was examined, in order to determine the extent to which angular velocity judgments are influenced by the tangential velocity of the faces. When the comparison cube's edges were half the length of the standard's, PSEs were elevated 18.5%. Taken together, these data suggest that observers are able to discriminate angular velocities with a competence near that for linear velocities. However, perceived angular rate is influenced by structural aspects of the stimuli. JF - Perception and Psychophysics AU - Kaiser, M K AD - NASA Ames Research Center, Moffett Field, CA 94035.

AN - 80422315; 11540757 AB - Gravitropic stimulation of maize (Zea mays L.) seedlings resulted in a continuous curvature of the coleoptiles in a direction opposing the vector of gravity when the seedlings were rotated on a horizontal clinostat. The orientation of this response, however, was reversed when the gravitropic stimulation was preceded by symmetric preirradiation with blue light (12.7 micromoles photons m-2). The fluence-response curve of this blue light exhibited a lower threshold at 0.5 micromole m-2, and could be separated into two parts: fluences exceeding 5 micromoles m-2 reversed the direction of the gravitropic response, whereas for a range between the threshold and 4 micromoles m-2 a split population was obtained. In all cases a very strong curvature resulted either in the direction of gravity or in the opposite orientation. A minor fraction of seedlings, however, curved towards the caryopsis. Furthermore, the capacity of blue light to reverse the direction of the gravitropic response disappeared with the duration of gravitropic stimulation and it depended on the delay time between both stimulations. This tonic blue-light influence appears to be transient, which is in contrast to the stability observed for tropistic blue-light effects.

General considerations of the dynamics of such an atmospheric warming indicate that transport of "tracers" such as dust to polar latitudes should take place, regardless of the specifie dynamical mechanism involved. Attention is focused upon a planetary wave induced polar warming, with a simplified transport model employed in conjunction with a beta-plane dynamical model to simulate the transport of dust during a warming event. Numerical experiments are performed to examine the influence of different warming dynamics and to assess the sensitivity of the transport to the initial (that existing in the early stages of a global dust storm) dust distribution. Several simulations incorporating sedimentation are carried out, allowing examination of dust deposition at polar latitudes. The results of the numerical simulations indicate that substantial amounts of dust could be transported and deposited at high northern latitudes (extending to the pole) in a polar-warming event. For a planetary wave warming the net transport is not very sensitive to the initial dust distribution (or to the details of the dynamics), as horizontal diffusive mixing plays a dominant role. Without such mixing (as might be the case if the dynamics does not involve planetary waves) the net transport is much more dependent on the initial state, with relatively elevated dust distributions favoring enhanced poleward transport. The potential for the transport of water is also examined, through several simulations in which condensation is neglected. These indicate that large amounts of water could be transported to the north polar region in a warming, given that substantial condensation and precipitation do not take place in subpolar regions. The warmth of the Martian atmosphere during global dust storms makes the latter plausible. The implications and significance of the transport of dust, as well as water, to high northern latitudes in global dust storm/polar warming events are discussed, in the context of the Mars climate system and the polar layered terrains.

It can be covered all year by CO (sub 2) frost, as was observed by the Viking spacecraft, or the CO (sub 2) frost can disappear at midsummer to expose an underlying surface. The difference between the two states depends on the role of energy conducted into the subsurface: If the cap was exposed the previous year, conducted energy will cause less CO (sub 2) frost to condense in winter, and the frost will disappear completely in summer; if the cap was covered the previous year, there will be no conducted energy, and it will stay covered again. Subtle effects in the atmosphere can perturb the cap energy balance sufficiently to cause the cap to jump between states. This behavior might provide an explanation for the large southern summer water vapor abundances observed in 1969. It also explains the observed differences between the north and the south residual caps as resulting in part from a difference in the role in the annual energy balance of energy conducted into the subsurface.

The calculated seasonal and spatial patterns of occurrence of water ice clouds are qualitatively similar to the observed polar hoods, suggesting that these polar clouds are, in fact, an important component of the water cycle. A residual dry ice cap in the south acts as a cold trap which, in the absence of sources other than the caps, will ultimately attract the water ice from the north cap; however, in the presence of a source of water in northern mid-latitudes during spring, it is possible that the observed distribution of vapor and ice can be in a steady state even if a residual CO (sub 2) cap is a permanent feature of the system.

The gravity wave parameterization employed is basically the saturation parameterization of Lindzen (1981) which has been utilized in several terrestrial modeling studies. Numerical simulations are performed for a range of plausible values of the gravity wave parameters and for different representations of the mean flow thermal forcing, with a focus on the effects of topographically forced stationary gravity waves on the winter hemisphere circulation. The results of the model simulations show that breaking gravity waves (of intermediate horizontal scales, approximately 100-1000 km wavelengths) could act to "close off" the winter westerly circumpolar jet in the approximately 40-80 km altitude region and induce strong high-latitude warming at these levels. The latter could explain recent thermal measurements indicating that Martian winter polar latitudes may be very warm, far above radiative equilibrium, in this middle atmospheric region [Deming et al., 1986]. For the most plausible range of parameter values breaking gravity waves do not induce much warming below approximately 40 km, consistent with available data showing that winter high latitudes are normally very cold at lower levels. Several "dust storm" cases indicate that breaking gravity waves possibly could act to induce a very large polar warming at relatively low altitudes, such as was observed during the 1977 winter solstice dust storm. However, quite large gravity wave amplitudes and/or relatively long horizontal wavelengths are required for such strong low-level effects; thermal forcing associated with dust heating might be a source for such anomalous gravity wave activity during a global dust storm. Summer simulations indicate that breaking gravity waves might alter the mean flow at somewhat higher levels than in the winter hemisphere, as a consequence of the presence of westerlies in the lower atmosphere. This could explain the presence of a warm summer pole in the recent 50-80 km thermal measurements of Deming et al. Several aspects of the results relating to the middle atmospheric circulation and the polar warming phenomenon are discussed. The possible importance of breaking gravity waves for constituent transports in the middle atmosphere of Mars is also briefly considered.

The radiative effects of atmospheric dust on solar and thermal radiation have been incorporated into the model. It has 13 vertical layers that span the altitude range from the surface to approximately 47 km and a horizontal resolution of 7.5 degrees latitude by 9 degrees longitude. A large number of numerical experiments were conducted for alternative choices of seasonal date and dust optical depth. During each experiment the dust optical depth was kept constant in time, and the amount of dust was constant in space as well, except for the effects of topography. Carbon dioxide condensed in the atmosphere as well as at the ground in the winter polar regions over the entire range of dust optical depths considered (0-5). However, the rate of atmospheric CO (sub 2) condensation increased sharply as the dust content of the winter polar region increased. The simulated properties of atmospheric CO (sub 2) condensation imply that CO (sub 2) ice clouds are chiefly responsible for the occurrence of anomalously low brightness temperatures in the winter polar regions and that they manifest themselves at optical wavelengths as polar hoods. A number of hemispherical asymmetries may ultimately be due to the strong seasonal variation in the atmospheric dust content and to feedback relationships between the dust optical depth on the one hand and the magnitude of poleward heat transport and the rate of atmospheric CO (sub 2) condensation on the other hand. These asymmetries include the greater prevalence of polar hoods in the northern polar region during winter, the lower albedo of the northern polar cap during spring, and the total dissipation of the northern CO (sub 2) ice cap during the warmer seasons.

We believe that small-scale processes are a key for enhanced understanding of the global water behavior of Mars. The principal data for this study of small scale properties of the Martian surface were collected by the second Viking lander (VL 2) and by both Viking orbiters. The annual deposition and retreat of the frost layer were observed in situ by VL 2. The frost is inferred to be H (sub 2) O frost but with some properties suggesting a much thicker layer than would be expected from the simple mass balance calculation. Our original contribution is in considering the effect of cold trapping (frost redeposition) which has been previously neglected and which enables us to reconcile all the observations with environmental conditions. In addition, we believe that this study points to a more general phenomenon of cold trapping in the Martian environment. Our study of the VL 2 observations suggests that H (sub 2) O frost occurs in two forms: (1) thin, almost continuous, early frost and (2) much thicker, patchy, later frost. Both frost forms contain essentially the same total water content, but they cover different fractions of the surface. The transition between the two frost forms occurs by recondensation at local cold traps when solar insolation sublimates the first frost but the atmosphere is still too cold to transport the resultant water vapor away. These cold traps are created by shadowing from the small-scale surface roughness, rocks, troughs, etc. This hypothesis hinges on the disparity between local and long-range transport of water vapor by the atmosphere. The local transport is driven by abundant insolation energy available at the time of transition. This results in a large fraction of surface frost being redistributed rapidly into locally thermodynamically preferable locations, cold traps. Long-range transport is constrained by the atmospheric carrying capacity. At the time of transition, the atmosphere is still cold, not far from its winter minimum, and is almost saturated by residual water vapor (5-8 precipitable micrometers). Therefore it cannot carry much additional water vapor to lower latitudes. This disparity delays the global transport of water vapor by the atmosphere.

The 1986 regression appears to have been unexceptional until after L (sub s ) = 230 degrees , when it becomes retarded relative to the normal established by the 1971 and 1977 regressions. A study of the data as a function of the filter used suggests that circumpolar clouds were present in early spring, unlike the case in the 1977 recession.

We have explored the role of the north residual cap in the current Martian water cycle by constructing models to assess the ability of the cap to supply water to the atmosphere and the ability of the atmosphere to transport it out of the polar regions. From our sublimation model we conclude that the residual cap can sublime the 7 X 10 (super 14) g of water that appears in the atmosphere after L (sub s ) = 80 degrees provided surface winds are high ( approximately 10 m/s), the cap emissivity is low ( approximately 0.9), or the exposed soil in polar regions contains ice that is accessible to the atmosphere. In our view these requirements seem unlikely, and we are drawn to the conclusion that other sources of water exist. This conclusion is further supported by the results of two-dimensional transport simulations which show that most of the water sublimed from the cap remains at high latitudes. The polar circulation simply lacks the intensity and scale to move water very far from the cap. A weak circulation places additional constraints on cap sublimation rates since abundant clouds and significant ice deposits would form just equatorward of the cap edge, according to the model, if the cap is allowed to sublime 7 X 10 (super 14) g of water. Such predictions are inconsistent with available data. We suggest that the nature of the additional source is water desorbing from the nonpolar regolith.

AN - 50187147; 1990-024821 AB - Preferential escape of H relative to D will cause an enrichment of the atmospheric abundance of the latter over geological time. Measurement of atmospheric HDO and H (sub 2) O provides an estimate of this enrichment (Owen et al., 1988). By assuming an initial H/D ratio similar to the Earth's, Yung et al. (1988) constructed a photochemical model based on the current atmosphere to determine the relative escape rates; they concluded that regular exchange of atmospheric water with a nonatmospheric reservoir containing about 3 m of water was required and that all but 0.2m had escaped to space. This reservoir size appears to be inconsistent with current theories for evolution of the polar deposits, which suggest that they contain the equivalent of tens of meters of water and that this water exchanges on time scales which are short compared to the age of the planet. Solar forcing throughout the obliquity cycling may cause the time-averaged atmospheric water content to be larger than the current value, significantly increasing the escape rates and increasing the required size of the nonatmospheric reservoir to a value consistent with the content of the polar deposits. If an early, wet atmosphere is present, as discussed by Owen et al., the requirements for polar cap exchange are eased. It is premature to conclude that the escape theories are inconsistent with polar cap behavior; better observations and models may, in turn, constrain the content and history of the polar caps. The models do suggest, however, that at least 60 m of water has escaped from the surface and atmosphere to space over geologic time.

However, metamorphism of such material will gradually lower its albedo by increasing the size of the H (sub 2) O grains only. If the cap is undergoing net annual sublimation (as inferred from water vapor observations), late summer observations should be of old ice with H (sub 2) O grain sizes of 100 mu m or more. Ice of this granularity containing 30% fine dust has a reflectivity similar to that of dust alone; the observed albedo and computed ice grain size imply dust concentrations of 1 part per 1000 or less. The brightness of the icy areas conflicts with what would be expected for a residual cap deposited by an annual cycle similar to that observed by Viking and aged for thousands of years. The residual cap surface cannot be "old dirty" ice. It could be old, coarse, and clean; or it could be young, fine, and dirty. This brings into question both the source of the late summer water vapor and the formation rate of laminated terrain. Copyright 1990 by the American Geophysical Union.

Analyses of Viking orbiter observations obtained 3 Mars years later have shown that residual carbon dioxide frost was present at the south polar cap in 1977. In this study, Mariner 9 infrared interferometer spectrometer spectra and television camera images are used in conjunction with multispectral thermal emission models to constrain the temperatures of dark bare ground and bright frost regions within the south residual cap. The results provide strong evidence that carbon dioxide frost was present throughout the summer season despite the fact that the residual frost deposits observed by Mariner 9 were less extensive than those observed by Viking.

Atmospheric dust scattering was measured in shadows and modeled in order to remove the component of brightness in Mars images due to the atmosphere and quantify the albedo and color of the surface. The layered deposits appear to be mantled by red dust, except where eolian stripping has exposed the underlying bedrock. Frost and bare ground are mixed below the resolution of the images in many areas adjacent to the polar cap, some of which appear to be younger than the surrounding layered terrain. Dark material has been deposited in topographic depressions in much of the south polar region, including the layered deposits. The available observational data suggest that the layered deposits are composed of bright dust, ice, and a small amount of dark material. If the dark material is sand, a periodic change in polar winds seems required in order to transport the sand poleward into the layered terrain. In any case, the observations are not consistent with the layered deposits being composed only of bright dust and ice. The Mars observer camera and infrared instruments should be particularly useful in this investigation. Copyright 1990 by the American Geophysical Union.

This sampling error inherent in satellite monitoring of rainfall would occur even if the satellite instruments could measure rainfall perfectly. The size of this error for a satellite system being studied at NASA, the Tropical Rainfall Measuring Mission (TRMM) is estimated. The statistical description of rainfall on scales from 1 to 1000 km, based on rainfall data from the Global Atmospheric Research Project Atlantic Tropical Experiment (GATE), is examined in detail. A TRMM-like satellite is flown over a two-dimensional time-evolving simulation of rainfall using a stochastic model with statistics tuned to agree with GATE statistics. The distribution of sampling errors found from many months of simulated observations is found to be nearly normal, even though the distribution of area-averaged rainfall is far from normal. For a range of orbits likely to be employed by TRMM, sampling error is found to be less than 10 percent of the mean for rainfall averaged over a 500 x 500 square km area.

When averaged over a large scale (the GATE radar array, 400 km in diameter), the beam filling error is quite stable, being 50 percent of the observed rain rate. This suggests the simple procedure of multiplying retrieved rain rates by 2 (correction factor). A statistical model of the beam filling error is developed by envisioning an idealized instrument field-of-view that encompasses an entire gamma distribution of rain rates. A modeled correction factor near 2 is found for rain rate and temperature characteristics consistent with GATE conditions. The statistical model also suggests that (1) the correction factor varies from 1.5 to 2.5 for suppressed to enhanced tropical convective regimes and (2) decreases to 1.5 as the freezing level and average depth of the rain column decreases to 2.5 km.

The Height-Area Rainfall Threshold (HART) Method AN - 19071651; 9007588 AB - Estimates of instantaneous area average rain rate ((R) in millimeters per hour) are obtained with 5-10 percent accuracy over a large domain simply by measuring (1) the fraction of the area, F(tau), covered by rain intensity greater than a selected threshold tau and (2) the average precipitating cloud top heights. In order to achieve this high accuracy the domain has to be large enough (about 10,000 square km) to include a representative sample of rain cells in different stages of their life cycle, and the measurement of the threshold rain intensity (tau) has to be unbiased. This Height-Area Rainfall Threshold (HART) method was tested with radar data of convective rains from Global Atmospheric Research Program Tropical Atlantic Experiment phase 3, South Africa, west Texas, and a small sample from Darwin, Australia. The results from the locations were found to be consistent and physically plausible. The cloud base temperature seems to play a major role in the determination of the constants of the HART method. The (R)-F(tau) relations were found to be rather insensitive to variations in the Z-R relationships. However, any bias in the measurement of tau causes a similar bias in the derived (R). HART makes possible the accurate estimation of instantaneous rainfall from space when measuring the area and height of the convective rain systems with radar. Passive microwave observations may also be used over the ocean at wavelengths which allow setting a specified rain rate threshold, and when accompanied by infrared measurements of storm top temperatures. Over tropical ocean domains of the order of 10,000 square km or greater, the autocorrelation time of about 6 hours permits the area average instantaneous rate to represent the rate for a few hours.

AN - 80423040; 11543604 AB - Photolysis of cyanoacetylene with 185- or 206-nm light yields 1,3,5-tricyanobenzene while 254-nm radiation yields a mixture of tetracyanocyclooctatetraenes, 1,2,4- and 1,3,5-tricyanobenzene. A polymer of cyanoacetylene is the major photoproduct. 1,3,5-Tricarbomethoxybenzene was the only photoproduct identified from the irradiation of methyl propiolate at 254 nm. Mono-, di-, and tricyanobenzenes are formed by irradiation of mixtures of acetylene and cyanoacetylene at 185, 206, and 254 nm along with trace amounts of cyclooctatetraenes. No photoadducts were detected on photolysis of mixtures of cyanoacetylene and CO or HCN. The tetracyanocyclooctatetraene structures were established by UV, MS, and NMR analyses. The 1H NMR of the product mixture exhibited a singlet at delta 7.028 consistent with either 1 or 2 and two singlets at delta 6.85 and 6.91 assigned to 3. Photolysis of mixtures of dicyanoacetylene and acetylene with either 185- or 206-nm light yielded 1,2-dicyanobenzene and (E,Z)-1-buten-3-yne-1,4-dicarbonitrile. These products were also obtained using 254-nm light along with a mixture of tetracyanocyclooctatetraenes. The same three singlets were observed in this product mixture as were observed in the tetracyanocyclooctatetraenes obtained from cyanoacetylene. From this observation it was concluded that the delta 7.02 signal is due to 2 and not 1. The photolysis of cyanoacetylene and dicyanoacetylene in the presence of ethylene with 185-nm light yields 1-cyanocylobutene and 1,2-dicyanocyclobutene, respectively. 2-Cyanobutadiene and 2,3-dicyanobutadiene are the photoproducts with 254-nm light. Reaction pathways are proposed to explain these findings.

AN - 80423000; 11540917 AB - Thermal configurational data on neat liquids are used to obtain the work of formation of hard spherical cavities of atomic size in six molecular solvents: n-hexane, n-dodecane, n-undecyl alcohol, chloroform, carbon tetrachloride, and water. These results are used to test a recent suggestion that the differences between nonaqueous solvents and liquid water in solvation of inert gases are not principally due to the hydrogen-bonded structure of liquid water but rather to the comparatively small size of the water molecule. The frequencies of occurrence of cavities in liquid water can be meaningfully distinguished from those in the organic solvents. Liquid water has a larger fractional free volume, but that free volume is distributed in smaller packets. With respect to cavity work, water is compared to a solvent of the same molecular density and composed of hard spheres of the same size as the water molecule. That comparison indicates that the hard-sphere liquid finds more ways to configure its free volume in order to accommodate an atomic solute of substantial size and thus, would be more favorable solvent for inert gases. The scaled particle model of inert gas solubility in liquid water predicts cavity works 20% below the numerical data for TIP4P water at 300 K and 1.0 g/cm3 for cavity radii near 2.0 angstroms. It is argued that the sign of this difference is just the sign that ought to be expected and that the magnitude of this difference measures structural differences between water and the directly comparable hard-sphere liquid. In conjunction with previous data, these results indicate that atomic sized cavities should be considered submacroscopic.

AN - 80422569; 11537512 AB - The potentially specific importance of the study of heavy ions from galactic cosmic rays for the understanding of radiation protection in manned spaceflight continues to stimulate spaceflight experiments in order to investigate the radiobiological properties of these ions. Chromosome aberrations as an expression of a direct assault on the genome are of particular interest in view of carcinogenesis as the primary radiation risk for man in space. An essential technical ingredient of such spaceflight experiments is the visual nuclear track detector which permits identification of those biological test organisms which have been affected by cosmic heavy ions. We describe such a technique and report on an analysis of the qualitative and quantitative reliability of this identification of particle trajectories in layers of biological test organisms. The incidence of chromosome aberrations in cells of lettuce seeds, Lactuca sativa, exposed during the Kosmos 1887 mission, was determined for seeds hit by cosmic heavy ions. In those seeds the incidence of both single and multiple chromosome aberrations was enhanced. JF - International Journal Of Radiation Applications And Instrumentation.

AN - 80422541; 11537511 AB - Investigations are described for the determination of dose distributions of cosmic radiation behind different shielding thicknesses. For this purpose, ultra-thin thermoluminescent detectors on a base of CaF2-polytetrafluorethylene (PTFE) were prepared and arranged in a stack at the outer wall of the biosatellite Cosmos 1887. During the 13 days of flight in a near-Earth orbit, the detectors were exposed to the unshielded cosmic radiation. After the flight, the dose distribution in the stack was determined by successive evaluations of the CaF2-PTFE discs. In the upper layers of the detector arrangement, dose values up to 100 Gy were observed. The strong decrease of the dose within a few mm demonstrates that weak particle radiation is dominant in the radiation field under investigation.

AN - 80421069; 11537514 AB - Among the biological problems that arise in long duration spaceflights, the effects of weightlessness and ionizing radiation appear to be the two main risk factors. Eggs of the stick insect Carausius morosus were exposed to spaceflight conditions during the 12.56 day Biosatellite mission Cosmos 1887. Five different ages were used, representing different sensitivities to radiation and different capacities for regeneration. During spaceflight the eggs continued their development. Already, in the Spacelab D1 mission in 1985, it has been shown that microgravity leads to a reduced hatching rate of eggs exposed during the early steps of development. When the eggs were hit by a heavy ion, a further but not significant reduction of the hatching rate was observed. Hatching was normal for eggs which were exposed on a 1 g reference centrifuge in space. Heavy ion hits caused body anomalies. The combined action of heavy ions and microgravity resulted in an unexpectedly high rate of anomalies. In the experiment on Cosmos 1887 these results were confirmed. Studies on the embryonic development before hatching showed no major difference between flight and ground control specimen, neither in speed of development nor in morphological anomalies. Hatching therefore seems to be the critical point in insect ontogenesis. JF - International Journal Of Radiation Applications And Instrumentation.

The measurements of heavy ions were performed simultaneously on the Cosmos 1882 (orbital inclination 82 degrees) and Cosmos 1887 (inclination 62.3 degrees) satellites during September-October 1987. Solid state nuclear track detector stacks were used for the registration of C, N, O and heavier ions. After comparing the data of the two experiments with theoretical calculations, the charge state of galactic and anomalous heavy ions was derived.

Two kinds of measurements were performed on the external surface of the satellite. First, the fluences and spectra of low energy charged particles were established. It was found that most of the particles registered by means of solid state nuclear track detectors are helium nuclei. Tracks of oxygen nuclei and some heavier charged particles were also observed. Thermoluminescent detectors were used to establish absorbed doses in open space on the satellite's surface and behind thin shielding. It was found that these doses were rather high; nevertheless, their decrease with shielding thickness is very rapid. Dosimetric and other consequences of the results obtained are analyzed and discussed. JF - International Journal Of Radiation Applications And Instrumentation.

AN - 80420950; 11540919 AB - Patterns of isotopic fractionation in biogeochemical processes are reviewed and it is suggested that isotopic fractionations will be small when substrates are large. If so, isotopic compositions of biomarkers will reflect those of their biosynthetic precursors. This prediction is tested by consideration of results of analyses of geoporphyrins and geolipids from the Greenhorn Formation (Cretaceous, Western Interior Seaway of North America) and the Messel Shale (Eocene, lacustrine, southern Germany). It is shown (i) that isotopic compositions of porphyrins that are related to a common source, but which have been altered structurally, cluster tightly and (ii) that isotopic differences between geolipids and porphyrins related to a common source are equal to those observed in modern biosynthetic products. Both of these observations are consistent with preservation of biologically controlled isotopic compositions during diagenesis. Isotopic compositions of individual compounds can thus be interpreted in terms of biogeochemical processes in ancient depositional environments. In the Cretaceous samples, isotopic compositions of n-alkanes are covariant with those of total organic carbon, while delta values for pristane and phytane are covariant with those of porphyrins. In this unit representing an open marine environment, the preserved acyclic polyisoprenoids apparently derive mainly from primary material, while the extractable, n-alkanes derive mainly from lower levels of the food chain. In the Messel Shale, isotopic compositions of individual biomarkers range from -20.9 to -73.4% vs PDB.

AN - 80420720; 11537513 AB - Artemia (Brine shrimp) cysts and tobacco seeds, dormant biological material devoid of metabolic activity, were flown aboard the Soviet Biocosmos 1887 in order to investigate the effects of cosmic rays. Artemia cysts and tobacco seeds were used in bulk or in monolayers sandwiched with track detectors. Biological and physical units were located outside and inside the spacecraft. Stacks included lead shielding in order to expose the objects to different doses of radiation. Total dosimetry was performed using thermoluminescent detectors. In spite of low levels of doses, the space flight resulted in a decrease in developmental capacity of Artemia cysts, and in a higher mutation rate in tobacco seeds. The more obvious responses occurred, in both cases, in biological objects exposed to the highest doses. These results are compared to those of previous space experiments.

AN - 80419525; 11537517 AB - Monocrystalline sheets of AgCl nuclear track detectors, mounted on top of a detector package, covered by a thin light-filter of 15 micrometers-thick Kapton-foil, were flown in the outside facilities of the Biokosmos 8 Mission. The aim of this lay-out was to record low energy protons and heavy ions, including SAA particles, from the unshielded cosmic radiation. The tracks recorded turned out to be strongly faded. The possible reasons, high temperature (>60 degrees C at the detector surface indicated by temperature markers) or too high temporary intensities of the filtered sunlight, are discussed on the basis of simulation experiments. The report briefly describes: (1) Characteristics of the AgCl-detectors. (2) The lay-out of the experiment, postflight handling and results. (3) Simulation experiments on the ground with respect to the observed fading. (4) A new lay-out proposed for a future analogous experiment with AgCl-detectors.

AN - 80419493; 11537515 AB - In September 1987 dry seeds containing embryos of the crucifer plant Arabidopsis thaliana (L.) Heynh, were flown in orbit for 13 days on the Kosmos 1887 satellite. The seeds were fixed on CNd detectors and stored in units of Biorack type I/O. One unit was exposed inside, another one outside the satellite. The temperature profile of the flown seeds inside the satellite was simulated on earth in an identical backup control sample (BC). An additional control (SC) was studied with the original seeds sample. By use of the CNd-detector, HZE-tracks were measured with a PC-assisted microscope. The biological damages were investigated by growing the seeds under controlled climatic conditions. The following biological endpoints of the cosmic radiation damage were studied: germination, radicle length, sublethality, morphological aberrations, flower development, tumorization, embryo lethality inside the siliques. The summarized damage (D) and the mutation frequencies of embyronic lethal genes were calculated. The following results were obtained: the damages increase significantly in orbit at all biological endpoints; germination and fiowerings especially, as well as embryo lethality of fruits and lethal mutation frequency, were maximum mostly for HZE-hit seeds. Additionally, an increase of damage was observed for the seeds of the outside-exposed Biorack in comparison to the inside ones, which was probably caused by less radiation shielding and free space vacuum. The significance of the results obtained is discussed with respect to stress and risk and, thus, the quality of the RBE-factors and heavy ionizing radiation all needed for the very definition of radiation protection standards in space.

AN - 80417279; 11538484 AB - Multiplex gas chromatography (MGC) is a technique in which multiple samples may be introduced into a chromatographic system regardless of the elution time of the individual components. Although the output obtained from a MGC experiment is not directly interpretable, computational techniques can be used to obtain the chromatogram from the detector output data. This is done by calculating the impulse response function from the multiplexed output data.

AN - 80415370; 11537475 AB - We tested the involvement of ethylene in maize (Zea mays L.) root gravitropism by measuring the kinetics of curvature and lateral auxin movement in roots treated with ethylene, inhibitors of ethylene synthesis, or inhibitors of ethylene action. In the presence of ethylene the latent period of gravitropic curvature appeared to be increased somewhat. However, ethylene-treated roots continued to curve after control roots had reached their final angle of curvature. Consequently, maximum curvature in the presence of ethylene was much greater in ethylene-treated roots than in controls. Inhibitors of ethylene biosynthesis or action had effects on the kinetics of curvature opposite to that of ethylene, i.e. the latent period appeared to be shortened somewhat while total curvature was reduced relative to that of controls. Label from applied 3H-indole-3-acetic acid was preferentially transported toward the lower side of stimulated roots. In parallel with effects on curvature, ethylene treatment delayed the development of gravity-induced asymmetric auxin movement across the root but extended its duration once initiated. The auxin transport inhibitor, 1-N-naphthylphthalamic acid reduced both gravitropic curvature and the effect of ethylene on curvature. Since neither ethylene nor inhibitors of ethylene biosynthesis or action prevented curvature, we conclude that ethylene does not mediate the primary differential growth response causing curvature. Because ethylene affects curvature and auxin transport in parallel, we suggest that ethylene modifies curvature by affecting gravity-induced lateral transport of auxin, perhaps by interfering with adaptation of the auxin transport system to the gravistimulus.

AN - 80414815; 11538281 AB - Tobacco plants (Nicotiana tabacum L. cv NC82) were supplied with (NH4)2SO4 or NH4Cl at root-zone pH of 6.0 and 4.5 in hydroponic culture for 28 days. Dry matter accumulation, total N and C content, and leaf area and number were not affected by the NH4+ source or root-zone pH. Plants supplied with NH4Cl accumulated up to 1.2 mM Cl g DW-1, but accumulated 37% less inorganic H2PO4- and 47% less SO4(2-) than plants supplied with (NH4)2SO4. The large Cl- accumulation resulted in NH4Cl- supplied plants having a 31% higher inorganic anion (NO3-, H2, PO4-, SO4(2-), and Cl-) charge. This higher inorganic anion charge in the NH4Cl-supplied plants was balanced by a similar increase in K+ charge. Plants supplied with NH4Cl accumulated greater concentrations of Cl- in leaves (up to 5.1% of DW) than plants supplied with (NH4)2SO4 (less than -% DW). Despite the high Cl- concentration of leaves in NH4Cl supplied plants, these plants showed no symptoms of Cl- toxicity. This demonstrates that toxicity symptoms are not due solely to an interaction between high Cl- concentration in tissue and NH4+ nutrition. The increase in root-zone acidity to pH 4.5 from 6.0 did not induce toxicity symptoms.

AN - 80414671; 11538077 AB - To circumvent the limitations of chemical fixation (CF) and to gain more reliable structural information about higher plant tissues, we have cryofixed root tips of Nicotiana and Arabidopsis by high pressure freezing (HPF). Whereas other freezing techniques preserve tissue to a relatively shallow depth, HPF in conjunction with freeze substitution (FS) resulted in excellent preservation of entire root tips. Compared to CF, in tissue prepared by HPF/FS: (1) the plasmalemma and all internal membranes were much smoother and often coated on the cytoplasmic side by a thin layer of stained material, (2) the plasmalemma was appressed to the cell wall, (3) organelle profiles were rounder, (4) the cytoplasmic, mitochondrial, and amyloplast matrices were denser, (5) vacuoles contained electron dense material, (6) microtubules appeared to be more numerous and straighter, with crossbridges observed between them, (7) cisternae of endoplasmic reticulum (ER) were wider and filled with material, (8) Golgi intercisternal elements were more clearly resolved and were observed between both Golgi vesicles and cisternae, and (9) larger vesicles were associated with Golgi stacks. This study demonstrates that HPF/FS can be used to successfully preserve the ultrastructure of relatively large plant tissues without the use of intracellular cryoprotectants.

AN - 80414361; 11537995 AB - Pea (Pisum sativum L.) ornithine transcarbamylase (OTC) antisera were used to investigate the immunological relatedness of several plant and animal OTC enzymes. The antisera immunoprecipitated OTC activity in all monocot and dicot species tested, and sodium dodecyl sulfate polyacrylamide gel electrophoresis analysis of immunoprecipitated protein revealed monomeric proteins ranging from 35,200 to 36,800 daltons in size. Pea OTC antisera did not recognize mammalian OTC protein. OTC activity and protein levels detected on sodium dodecyl sulfate polyacrylamide gel electrophoresis immunoblots from homogenates of green leaf, etiolated epicotyl and cotyledon, and root tissues of pea were poorly correlated. This might result from differences in amounts of enzymatically active OTC protein in the homogenates. Alternatively, the antisera may fail to recognize different isozyme forms of OTC, which have been reported for some plant species. A putative cytosolic precursor OTC (pOTC) polypeptide exhibiting and Mr = 39,500 to 40,000 daltons was immunoprecipitated from in vitro translation mixtures of total pea leaf poly(A)+ RNA. The size of the pOTC polypeptide, as compared with mature OTC monomer (36,000 daltons), suggests that a 4 kilodalton N-terminal leader sequence, like that responsible for mitochondrial targeting of the mammalian enzyme, may be involved in organellar import of the plant enzyme.

AN - 80414322; 11537476 AB - Gravitropism in dark-grown hypocotyls of the wild type was compared with a starch-deficient Nicotiana sylvestris mutant (NS 458) to test the effects of starch deficiency on gravity sensing. In a time course of curvature measured using infrared video, the response of the mutant was greatly reduced compared to the wild type; 72 hours after reorientation, curvature was about 10 degrees for NS 458 and about 70 degrees for wild type. In dishes maintained in a vertical orientation, wild-type hypocotyls were predominantly vertical, whereas NS 458 hypocotyls were severely disoriented with about 5 times more orientational variability than wild type. Since the growth rates were equal for both genotypes and phototropic curvature was only slightly inhibited in NS 458, the mutation probably affects gravity perception rather than differential growth. Our data suggest that starch deficiency reduces gravitropic sensitivity more in dark-grown hypocotyls than in dark- or light-grown roots in this mutant and support the hypothesis that amyloplasts function as statoliths in shoots as well as roots.

Particular emphasis is placed on results of the Cosmos 1887 biosatellite which carried a set of joint U.S.S.R.-U.S.A. radiation experiments involving passive detectors that included thermoluminescent detectors (TLDs), plastic nuclear track detectors (PNTDs), fission foils, nuclear photo-emulsions, etc. which were located both inside and outside the spacecraft. Measured LET spectra are compared with those theoretically calculated. Results show that there is some dependence of LET spectra on orbital parameters. The results are used to estimate the CR quality factor (QF) for the Cosmos 1887 mission. JF - International Journal Of Radiation Applications And Instrumentation.

AN - 80413675; 11537516 AB - The effects of spaceflight factors on the seeds of Arabidopsis thaliana and Crepis capillaris were studied provided with various protective measures: the seeds were located inside the satellite and in open space, protected with aluminium foil and also exposed without the foil cover. When the seeds were in open space without any protection, their viability was found to be suppressed; the survival rate and fertility of plants grown from these seeds were also diminished. An increase in the frequency of chromosome aberrations (CA) and in the number of multiple injuries was registered in this case. Experiments with the aluminium foil shielding showed a decrease in the suppression of the seeds' viability, but mutational changes were found to be even more increased, while the survival and fertility of the plants decreased. An increase in the thickness of shielding resulted in a decrease in the effects up to the level of the control, except for the effects connected with CA and fertility of the plants. Analysis of the results shows that these impairments can be ascribed to the action of single heavy charged particles (HCP). The seeds can be thus regarded as an integral biological 'dosimeter' which allows estimation of the total effects of radiation, ecological and biological factors.

AN - 80413531; 11537508 AB - Significant absorbed dose levels exceeding 1.0 Gy day-1 have been measured on the external surface of the Cosmos 1887 biosatellite as functions of depth in stacks of thin thermoluminescent detectors (TLDs) of U.S.S.R. and U.S.A. manufacture. The dose was found to decrease rapidly with increasing absorber thickness, thereby indicating the presence of intensive fluxes of low-energy particles. Comparison between the U.S.S.R. and U.S.A. results and calculations based on the Vette Model environment are in satisfactory agreement. The major contribution to the dose under thin shielding thickness is shown to be from electrons.

AN - 80413366; 11537519 AB - Two methods for measuring neutrons in the range from thermal energies to dozens of MeV were used. In the first method, alpha-particles emitted from the 6Li(n,alpha)T reaction are detected with the help of plastic nuclear track detectors, yielding results on thermal and resonance neutrons. Also, fission foils are used to detect fast neutrons. In the second method, fast neutrons are recorded by nuclear photographic emulsions (NPE). The results of measurements on board various satellites are presented. The neutron flux density does not appear to correlate clearly with orbital parameters. Up to 50% of neutrons are due to albedo neutrons from the atmosphere while the fluxes inside the satellites are 15-20% higher than those on the outside. Estimates show that the neutron contribution to the total equivalent radiation dose reaches 20-30%. JF - International Journal Of Radiation Applications And Instrumentation.

AN - 80413326; 11537470 AB - The relationship between the amount of light and the amount of response for any photobiological process can be based on the number of incident quanta per unit time (fluence rate-response) or on the number of incident quanta during a given period of irradiation (fluence-response). Fluence-response and fluence rate-response relationships have been measured for second positive phototropism by seedlings of Arabidopsis thaliana. The fluence-response relationships exhibit a single limiting threshold at about 0.01 micromole per square meter when measured at fluence rates from 2.4 x 10(-5) to 6.5 x 10(-3) micromoles per square meter per second. The threshold values in the fluence rate-response curves decrease with increasing time of irradiation, but show a common fluence threshold at about 0.01 micromole per square meter. These thresholds are the same as the threshold of about 0.01 micromole per square meter measured for first positive phototropism. Based on these data, it is suggested that second positive curvature has a threshold in time of about 10 minutes. Moreover, if the times of irradiation exceed the time threshold, there is a single limiting fluence threshold at about 0.01 micromole per square meter. Thus, the limiting fluence threshold for second positive phototropism is the same as the fluence threshold for first positive phototropism. Based on these data, we suggest that this common fluence threshold for first positive and second positive phototropism is set by a single photoreceptor pigment system.

AN - 80412763; 11537499 AB - The effect of SeO3= and SeO4= on NO3- assimilation in 8-d-old barley (Hordeum vulgare L.) seedlings was studied over a 24-h period. Selenite at 0.1 mol m-3 in the uptake solutions severely inhibited the induction of NO3- uptake and active nitrate reductases. Selenate, at 1.0 mol m-3 in the nutrient solution, had little effect on induction of activities of these systems until after 12 h; however, when the seedlings were pretreated with 1.0 mol m-3 SeO4= for 24 h, subsequent NO3- uptake from SeO4(=) -free solutions was inhibited about 60%. Sulphate partially alleviated the inhibitory effect of SeO3= when supplied together in the ambient solutions, but had no effect in seedlings pretreated with SeO3=. By contrast, SO4= partially alleviated the inhibitory effect of SeO4= even in seedlings pretreated with SeO4=. Since uptake of NO3- by intact seedlings was also inhibited by SO3=, the percentage of the absorbed NO3- that was reduced was not affected. By contrast, SeO4=, which affected NO3- uptake much less, inhibited the percentage reduced of that absorbed. However, when supplied to detached leaves, both SeO3= and SeO4= inhibited the in vivo reduction of NO3- as well as induction of nitrate reductase and nitrite reductase activities. Selenite was more inhibitory than SeO4= ; approximately a five to 10 times higher concentration of SeO4= than SeO3= was required to achieve similar inhibition. In detached leaves, the inhibitory effect of both SeO3= and SeO4= on in vivo NO3- reduction as well as on the induction of nitrate reductase activity was partially alleviated by SO4=. The inhibitory effects of Se salts on the induction of the nitrite reductase were, however, completely alleviated by SO4=. The results show that in barley seedlings SeO3= is more toxic than SeO4=. The reduction of SeO4= to SeO3= may be a rate limiting step in causing Se toxicity.

AN - 80412638; 11537090 AB - The plant root tip represents a fascinating model system for studying changes in Golgi stack architecture associated with the developmental progression of meristematic cells to gravity sensing columella cells, and finally to "young" and "old", polysaccharide-slime secreting peripheral cells. To this end we have used high pressure freezing in conjunction with freeze-substitution techniques to follow developmental changes in the macromolecular organization of Golgi stacks in root tips of Arabidopsis and Nicotiana. Due to the much improved structural preservation of all cells under investigation, our electron micrographs reveal both several novel structural features common to all Golgi stacks, as well as characteristic differences in morphology between Golgi stacks of different cell types. Common to all Golgi stacks are clear and discrete differences in staining patterns and width of cis, medial and trans cisternae. Cis cisternae have the widest lumina (approximately 30 nm) and are the least stained. Medial cisternae are narrower (approximately 20 nm) and filled with more darkly staining products. Most trans cisternae possess a completely collapsed lumen in their central domain, giving rise to a 4-6 nm wide dark line in cross-sectional views. Numerous vesicles associated with the cisternal margins carry a non-clathrin type of coat. A trans Golgi network with clathrin coated vesicles is associated with all Golgi stacks except those of old peripheral cells. It is easily distinguished from trans cisternae by its blebbing morphology and staining pattern. The zone of ribosome exclusion includes both the Golgi stack and the trans Golgi network. Intercisternal elements are located exclusively between trans cisternae of columella and peripheral cells, but not meristematic cells. In older peripheral cells only trans cisternae exhibit slime-related staining. Golgi stacks possessing intercisternal elements also contain parallel rows of freeze-fracture particles in their trans cisternal membranes. We propose that intercisternal elements serve as anchors of enzyme complexes involved in the synthesis of polysaccharide slime molecules to prevent the complexes from being dragged into the forming secretory vesicles by the very large slime molecules. In addition, we draw attention to the similarities in composition and apparent site of synthesis of xyloglucans and slime molecules.

AN - 80412600; 11537091 AB - Tip cells of dark-grown protonemata of the moss Ceratodon purpureus are negatively gravitropic (grow upward). They possess a unique longitudinal zonation: (1) a tip group of amylochloroplasts in the apical dome, (2) a plastid-free zone, (3) a zone of significant plastid sedimentation, and (4) a zone of mostly non-sedimenting plastids. Immunofluorescence of vertical cells showed microtubules distributed throughout the cytoplasm in a mostly axial orientation extending through all zones. Optical sectioning revealed a close spatial association between microtubules and plastids. A majority (two thirds) of protonemata gravistimulated for > 20 min had a higher density of microtubules near the lower flank compared to the upper flank in the plastid-free zone. This apparent enrichment of microtubules occurred just proximal to sedimented plastids and near the part of the tip that presumably elongates more to produce curvature. Fewer than 5% of gravistimulated protonemata had an enrichment in microtubules near the upper flank, whereas 14% of vertical protonemata were enriched near one of the side walls. Oryzalin and amiprophos-methyl (APM) disrupted microtubules, gravitropism, and normal tip growth and zonation, but did not prevent plastid sedimentation. We hypothesize that a microtubule redistribution plays a role in gravitropism in this protonema. This appears to be the first report of an effect of gravity on microtubule distribution in plants.

Concerns for human reproduction. AN - 79605316; 2405309 AB - Long-duration space flight and eventual colonization of our solar system will require successful control of reproductive function and a thorough understanding of factors unique to space flight and their impact on gynecologic and obstetric parameters. Part II of this paper examines the specific environmental factors associated with space flight and the implications for human reproduction. Space environmental hazards discussed include radiation, alteration in atmospheric pressure and breathing gas partial pressures, prolonged toxicological exposure, and microgravity. The effects of countermeasures necessary to reduce cardiovascular deconditioning, calcium loss, muscle wasting, and neurovestibular problems are also considered. In addition, the impact of microgravity on male fertility and gamete quality is explored. Due to current constraints, human pregnancy is now contraindicated for space flight. However, a program to explore effective countermeasures to current constraints and develop the required health care delivery capability for extended-duration space flight is suggested.

A range of sterols (C-26-C-30) was detected in the sea ice diatom communities; 24-methylenecholesterol, brassicasterol and 24-ethylcholesterol were the major sterols at the Cape Armitage, Erebus, Cape Evans and Wohlschlag Bay sites. The similarity of the sterol profiles to those observed in previous studies of antarctic freshwater algal communities strongly indicates that diatoms, rather than cyanobacteria or other algal groups previously proposed, are a more probable source of C-29 sterols in these extreme environments. Two novel 4-methyl-C-30 sterols were also detected: a C-30 sterol showing similar mass spectrum to 4-methyl-24-ethyl-5alpha-cholest-22-en-3beta-ol derived from the prymnesiophyte microalga Pavlova lutheri, but which was chromatographically resolved from this compound; and a stanol presumed to be derived from the C-30 sterol. 4-methyl C-30 sterols have not been reported previously in diatoms; their presence, and the occurrence of 4-methyl C-28 and C-29 sterols, may be due to temperature-induced adaptations in sterol biosynthetic pathways.

When these locations are compared with satellite derived ice edge locations in the mid 1970s, there is a suggestion of particularly heavy ice covers in the eastern Weddell Sea in Dec. 1772, in the Amundsen Sea in Mar. 1839, and in a portion of the western Weddell Sea in Jan. 1820. Many of the observations from the 4 expeditions indicate sea ice edge locations that lie within the range of ice edge locations at the same time of year in the mid 1970s, and a few of the observations suggest a less extensive ice cover than in the 1970s.

The common sedimentary methylhopanes are probably derived from biogenic precursors via diagenetic processes analogous to those which produce hopanes. Derivation of the 2alpha-methyl series from the 2alpha-methyl hopanoids found in certain bacteria, implies a maturity-related change in the configuration at C-2.

This increase might have caused global wildfires with the attendant effect on animal life.

In order to conserve the total angular momentum, its associated motion and mass redistribution will cause variations in the (solid) Earth's rotation, in both length of day (LOD) and polar motion. This paper examines the importance of ENSO in the excitation of Earth rotation variations by means of cross correlation in the time domain and complex coherence in the frequency domain. A Monte Carlo simulation is conducted to obtain estimates for the coherence confidence threshold that are needed, particularly as short spectral averages and tapering window functions are employed.

For real time satellite tracking, errors in extrapolated values for these quantities can be a major source of uncertainty. The largest error comes from variations in the Earth's rotation rate which cannot be accurately predicted. This report considers the use of the GPS constellation of navigation satellites to determine the Earth orientation parameters in near real time. The ORAN covariance analysis program has been used to simulate the full Block II constellation of 18 GPS satellites. The hypothetical GPS tracking network is coincident with the existing POLARIS VLBI network, operated expressly for the determination of earth orientation. Alternative network geometries have also been considered. As the reliability of any covariance analysis depends on the quality of the values assumed for the various tracking errors, considerable effort has gone into defining a reasonable error budget for these simulations. The simulations considered simultaneous solutions of Earth orientation together with the satellite orbits, ground clocks, station positions, and tropospheric scaling at each station. The principal contributors to Earth orientation uncertainty are found to be media effects and measurement noise. Simulation results show that a POLARIS-like network should be able to determine the Earth orientation parameters about as well as the current VLBI program, using single-difference carrier phase observations of the GPS satellites. GPS offers the potential of lower costs and faster data turn-around, making it an attractive alternative to VLBI. GPS determinations could be nearly 30 times better for UTl and perhaps 10 times better for pole position, compared with 10-day-old USNO predictions. Improvements of this magnitude are crucial for real time satellite tracking at the few meter level.

The Jarbo Gap ophiolite in the north consists of serpentinized harzburgite and dunite intruded by gabbro and diorite and overlain by volcanic and sedimentary rocks, all of which are metamorphosed to upper greenschist-amphibolite facies. Contacts between the ophiolitic subunits, which commonly have lenticular shapes, are generally tectonic and discontinuous along-strike. Ophiolitic rocks display a penetrative fabric of a west-northwest-striking and steeply to moderately north-northeast-dipping foliation. Locally, mafic to intermediate volcanic rocks within the ophiolite are cut by fault-bounded and/or diapiric intrusions of serpentinized peridotites. Contact relations and the rock types indicate that the Jarbo Gap ophiolite is part of a multiply deformed, heterogeneous oceanic crust. Marine rocks exposed south of and structurally beneath the Jarbo Gap ophiolite form a chert-argillite unit that is composed mainly of blocks of sedimentary, volcanic, plutonic, and ultramafic rocks in an argillite matrix. The matrix displays a northwest-trending, northeast-dipping penetrative foliation, whereas some of the blocks in the matrix show little or no deformation. Olistostromal origin of these undeformed blocks suggests that gravity debris sliding in addition to tectonic mixing was a significant agent for development of the generally chaotic internal structure of the chert-argillite unit. Ophiolitic blocks and detritus in the matrix indicate an older ophiolitic provenance, whereas blocks and clasts of relatively undeformed and fresh volcanic rocks, which occur as olistoliths in a mudstone-sandstone sequence, suggest volcanic activity adjacent to the depocenter(s) of the chert-argillite unit. Age relations, reconstructions of stratigraphic, structural, and contact relations, and regional correlations suggest that the Jarbo Gap ophiolite may have been originally overlain by the chert-argillite unit. Thus the Jarbo Gap ophiolite and the overlying chert-argillite unit are interpreted to have constituted a late Paleozoic-early Mesozoic oceanic basement. The existence of similar structural and stratigraphic relations between stratigraphically and chronologically correlative ophiolitic and marine rocks exposed in the Central Belt east of the Smartville complex suggests that much of the Central Belt is composed of this late Paleozoic-early Mesozoic oceanic basement. Both the Jarbo Gap ophiolite and the chert-argillite unit are intruded by dikes of a basaltic andesite composition that display low FeO and high MgO contents and enrichment in compatible as well as some LIL elements. These dikes, which are Lower Jurassic in age and chemically unrelated to the ophiolitic sequence, show petrographic and petrologic characteristics typical of boninitic affinity and are interpreted as products of primary melts generated by high degrees of melting of a metasomatically enriched source during early stages of subduction. We infer that this subduction during Early Jurassic time may have under-plated the preexisting oceanic basement and produced a submarine volcanic arc terrane. Part of the Smartville complex and the entire Slate Creek complex are interpreted as fragments of this arc terrane, which was built on and across the preexisting oceanic basement. This model suggests that the Western Belt and much of the Central Belt in the northern Sierra Nevada are part of a single ensimatic and polygenetic arc terrane that evolved in early Mesozoic time. This interpretation precludes tectonic scenarios suggesting the existence in the northern Sierra Nevada metamorphic belt of a number of discrete, exotic island-arc systems that were presumably accreted into the North American continental margin during early Mesozoic time. The current structural grain defined by northwest-striking and steeply northeast-dipping faults and associated structures is a relatively late-stage feature that modified the primary contact relations during a period of regional contraction in Late Jurassic to Early Cretaceous time.

It is important to understand the composition, distribution, and mineralogy of the ferric-bearing phases for the best spectral analogues because the correspondence in spectral properties implies that the nature of their ferric-bearing phases may be similar to those on Mars. In order to constrain interpretations of the martian data, a variety of palagonitic soils should be studied in order to establish to what extent differences in their spectral data correspond to differences in the mineralogy of their ferric-bearing phases. Reported here are spectral (350-2100 nm), Mossbauer, magnetic, and some compositional data for one of a suite of Hawaiian palagonitic soils we are studying. The soil (HWMKl) was collected below the biologically active zone from the sides of a gully cut at 9000 ft elevation on Mauna Kea.

The model is applied specifically to the Cretaceous/Tertiary impact. Three mechanisms for NO production by impacts are addressed: (1) a primary source caused by the passage of the impactor through the atmosphere; (2) a secondary source caused by the interaction of the atmosphere with the ejecta plume; and (3) a tertiary source caused by widely dispersed ejecta reentering the atmosphere. Thermal radiation from reentering ejecta may also have played a role in setting global fires. The primary source is most important for small impacts; the secondary and tertiary sources dominate for large impacts. Calculated primary and secondary production rates are insensitive to model details; tertiary production is sensitive to the (ill-known) size of the particles that condense directly from the rock vapor plume. Only the tertiary source is global. It can produce globally uniform NO (sub x) mixing ratios of order 0.5 percent in the upper stratosphere. The calculated total NO production for a normal impact at 20 km/sec by a 10-km asteroid is approximately x 10 (super 14) moles. Larger (or abnormal) impacts can give NO yields of approximately 10 (super 15) ergs. Enormous yields (> or =10 (super 17) moles) are only achievable in the modern atmosphere by heating most of the atmosphere to at least 1,500 degrees K.

It is found in all cases that only one likely periodicity exists in the range of possible periods longer than a million years: 33 + or - 3 m.y. This periodicity appears to be intrinsically semiregular, and the most recent epoch in the mean cycle is close to the present time. Purely internal explanations that have been proposed cannot yet accurately predict the order of magnitude of this geologic quasi-period and do not account for the similar quasi-period apparently detected in impact cratering. A possible extraterrestrial mechanism, however, is provided by comet impacts. Direct effects of large comet impacts on the Earth involve shock waves and debris put into the atmosphere-ocean system. Indirect effects follow from deep excavation of the lithosphere and extensive decompression melting of mantle rocks if the impact site is a hot-spot swell capping a mantle plume. Physical and statistical data for hot-spot swells and for terrestrial and lunar impact craters suggest that impacts which produce craters with diameters >100 km can account for the frequency and geographic distribution of continental flood basalts. Other geologic phenomena that may ensue from large impacts on the Earth include mantle-circulation disturbances, rifting, tectonism, sea-level fluctuations, magnetic reversals, and mass extinctions. A quasi-periodicity of approximately 33 m.y. in impact cratering could ultimately be caused by comet showers from the Solar System"s outer halo of comets, as a result of quasi-periodic gravitational encounters of the outer comet halo with massive interstellar dust clouds as the Solar System moves through the Milky Way Galaxy.

Analyses of the observed data showed only minor variation in microwave emissivity due to a change in organic matter content at a given moisture level for soils with similar texture and structure. Predictions of microwave emissivity made using a dielectric model for aggregated soils exhibited the same trends and type of response as the measured data when adjusted values for the input parameters were utilized.

We show that an enhanced cross-tail current earthward of this region would thin the plasma sheet substantially due to the magnetic pinch effect often studied in laboratory plasmas. This thinning would in turn affect the drift currents even closer toward the earth. In this way, a disruption and effective diversion of the cross-tail current throughout much of the inner portion of the plasma sheet could result and intense cross-tail current localized at the inner edge of the plasma sheet would lead to a very thin current-carrying region. This would explain the very taillike field and extreme particle dropouts often seen late in substorm growth phases. When the currents cannot be further enchanced within the inner plasma sheet (and when diffuse electron precipitation has sufficiently increased ionospheric conductivities) we expect an intense ( greater than or approximate to 10 super(6) A), very rapid increase of current flow through the auroral ionosphere. This latter phase would basically constitute the substorm expansion phase.

Future satellites (NOAA and DMSP) will carry microwave radiometers designed to measure the profile of water vapor globally. The problem of retrieving water vapor from the measurements is highly nonlinear even in clear atmospheres, and the addition of clouds only makes it more so. An algorithm has been developed which will retrieve water vapor profiles from microwave radiometric measurements even in the presence of clouds. Simulations with this algorithm show a vertical resolution on the order of 3 km; clouds are well handled in many circumstances. At low altitudes the performance is decidedly better over the ocean than over land backgrounds; above 5 km the background makes little difference. The most surprising result is that clouds can actually improve the vertical resolution of the retrieval.

The resulting (super 39) Ar- (super 40) Ar ages show no evidence of ages older than 4000 m.y., with average ages ranging 3450-3820 m.y. The Ar data indicate that a major thermal event occurred 4400 m.y. ago. Closure T against Ar loss are 2-340 degrees C, assuming a metallographic cooling rate of 1 degrees C/m.y., and this cooling occurred at approximately the ages derived from the Ar isotopic analyses. These ages also indicate a major collision with disruption and reassembly affecting the mesosiderite parent body < 3900 m.y. ago. Metal-silicate breccias were then buried under tens of km of rubble to cool slowly through the Ar closure T.

The distinctively fractionated Xe on Mars and Earth may lie in a common source from which both planets accreted. Xe would have been trapped in a porous large planetesimal as it grew and pores closed by lithostatic P; enough fractionated Xe to supply the Earth could have been trapped in this way. The degree of fractionation would have been controlled by lithostatic P at the pore-closing front. The predicted degree of fractionation agrees with that preserved in terrestrial and martian Xe. Prediction of the observed fractionation of Xe allows planetary accretion to occur after the dissipation of the solar nebula. The hypothetical planetesimals were large and now extinct in the solar system. Fractionation inside planetesimals is discussed and modelled, together with retention of Xe and other noble gases and diffusion times; potentially severe difficulties with the model are also raised.

Shergottites and Nakhla contain large proportions of their S as oxidized S compounds. Carbonate and sulphate abundances are inversely correlated, but total chlorine abundance varies directly with fractional sulphate abundance. Most volatile compounds appear to be anhydrous, although Nakhla might contain significant water chemically associated with chlorine. The shergottites and nakhlites experienced oxidizing, aqueous geochemical processes on their parent body, consistent with an origin on Mars.

AN - 16323882; 2839901 AB - Little is known about the mechanism of transport and distribution of volatile organic compounds in blood. Studied were conducted on five typical organic solvents to investigate how three compounds are transported and distributed in blood. Groups of four to five rats were exposed for 2 hr to 500 ppm of n-hexane, toluene, chloroform, methyl isobutyl ketone (MIBK), or diethyl ether vapor; 94, 66, 90, 51, or 49%, respectively, of these solvents in the blood were found in the red blood cells (RBCs). Very similar results were obtained in vitro when aqueous solutions of these solvents were added to rat blood. These results indicate that RBCs from humans and rats exhibited substantial differences in affinity for the three more hydrophobic solvents studied. When solutions of these solvents were added to human plasma and RBC samples, large fractions (51-96%) of the solvents were recovered from ammonium sulfate-precipitated plasma proteins and hemoglobin. Smaller fractions were recovered from plasma water and red cell water.

AN - 15988014; 2560984 AB - Estimation of biological risk from energetic protons (above 15 MeV) is provided by using a quality factor, Q sub(F), of unity as suggested by various national and international commissions. It is well known that collisions of energetic protons with target nuclei yield numerous nuclear products of large linear energy transfer (LET). It is customary to assume that the energy of the heavy products is absorbed locally with a quality factor of 20. This locally absorbed energy is large, compared with the ionization of the passing proton, and is a major contribution to biological risk in high-energy proton radiation fields. Past methods of risk assessment have relied on the Bertini model to evaluate the nuclear reaction products. JF - Health Physics AU - Shinn, J L AU - Wilson, J W AU - Ngo, D M AD - NASA Langley Res.

AN - 15969046; 2535654 AB - The NASA Langley Research Center has completed a comprehensive research program that resulted in the development of a generalized model for estimating passenger discomfort response to combined noise and vibration. This model accounts for multiple frequency and multiple axes of vibration as well as the interactive effects of combined noise and vibration. The model has the unique capability of transforming individual components of a noise/vibration environment into subjective comfort units and then combining these comfort units to produce a total index of passenger discomfort and useful sub-indices that typify passenger comfort within the environment. This paper presents an overview of the model development including the methodology employed, major elements of the model, model applications, and a brief description of a commercially available portable ride comfort meter based directly upon the model algorithms. Also discussed are potential criteria formats that account for the interactive effects of noise and vibration on human discomfort response.

AN - 15825190; 2427611 AB - The October rains (at the onset of the rainy season that extends to April) in southern Israel have steeply increased in the last quarter century relative to the prior two decades. A less pronounced, but appreciable, increase in noted for the rest of the rainy season. This apparent reversal of desertification is attributed here to land use changes. Afforestation, increased cultivation and limitations on grazing after the establishment of the State of Israel resulted in an increased vegetation cover over the inherently high-albedo soils in this region (an area of similar to 10 super(4) Km super(2)). The changes are shown in a July 1985 Landsat image of the area. JF - BOUNDARY-LAYER METEOROL.

AN - 15813282; 2411553 AB - Plant nutrient status and physiological processes were examined in relation to soil nutrient characteristics under individuals of five species colonizing a young cinder deposit in Hawaii Volcanoes National Park. Two exotic species, Buddeleja asiatica and Myrica faya , had high photosynthetic rates and high nitrogen concentrations and relatively easily decomposed leaves; soils under them had high concentrations of nitrogen, cations, and organic matter and high rates of net nitrogen mineralization. At the other extreme, the natives Metrosideros polymorpha and Vaccinium reticulatum had low plant concentrations and photosynthetic rates, and low concentrations and turnover rates of N in the soil. Thus, a strong correlation exists between soil processes and plant processes, suggesting a positive feedback cycle. JF - Oecologia AU - Matson, P AD - Ecosyst. Sci. and Technol.

AN - 15807277; 2407611 AB - Monthly surveys were conducted on Kennedy Space Center for one year to determine densities of waterbirds within impounded salt marshes that were predominantly open water with little emergent vegetation. The objective was to assess the importance of these impoundments to waterbirds, particularly wading birds, which are species of special conservation concern. Water-level management for mosquito control and waterfowl provided habitat for an abundance of ducks, shorebirds, coots, and wading birds. Shorebirds were most common during spring migration. Wading bird densities increased with declining water level. Due to the extensive alteration and development of coastal wetlands in central Florida, properly managed impoundments may provide important feeding areas for maintaining certain waterbird populations.

AN - 15749689; 2361542 AB - A review of case reports, hypobaric chamber training data, and experimental evidence indicated that the threshold for incidence of Altitude Decompression Sickness (DCS) was influenced by various factors such as prior denitrogenation, exercise or rest and period of exposure, in addition to individual susceptibility. Fitting these data with appropriate statistical models has the potential for estimating the frequency of occurrence of DCS at various altitudes under different experimental conditions and allows us to examine the influence of various factors on the threshold for DCS. This approach was illustrated by logistic regression analysis on the incidence of DCS below 9,144 m (30,000 ft). Estimations using these regressions showed that under a no-prebreathe, 6-h exposure, simulated extravehicular activity profile, the threshold for symptoms occurred at approximately 3,353 m (11,000 ft); while under a no-prebreathe, 2-h exposure profile with knee-bends exercise, the threshold occurred at 7,925 m (26,000 ft).

AN - 15746575; 2361318 AB - Gross nitrification rates (calculated by super(15)N pool dilution) ranged from 12 to 46% of gross mineralization rates during the growing season of annual grasses. Pools of NH sub(4) super(+) and NO sub(3) super(-) (measured as N) remained below 7 and 4 mu g/g soil, respectively, but turned over about once a day. Microbial assimilation of NO sub(3) super(-) occurred at rates similar to previous estimates of plant uptake. Hence two common assumptions, that nitrifying bacteria are poor competitors for NH sub(4) super(+) and that microbial immobilization of NO sub(3) super(-) is insignificant, are not correct for this grassland system. Soil heterogeneity probably results in NH sub(4) super(+) availability to NH sub(4) super(+) oxidizers at some microsites, while NO sub(3) super(-) assimilation by heterotrophic microorganisms occurs at other microsites where NH sub(4) super(+) is not available.

AN - 15744007; 2357224 AB - The bidirectional reflectance patterns of a complete (dense) canopy are examined as functions of canopy architecture, as specified by azimuth angle delta sub(e) and zenith angle psi for a leaf normal. Simple analytical expressions for the bidirectional reflectance factor are presented and analysed. The maximum bidirectional reflectance occurs at large viewing zenith angles (i.e. close to the horizon). The maximum reflectance is always higher for a delta sub(e) = 0 canopy than for a delta sub(e) = pi canopy, but the differences become small when psi approaches 1/2 pi . The bidirectional reflectance thus depends on the leaf azimuth as well as the zenith angle. Leaf-area azimuthal distributions should be considered when conducting model inversions to infer canopy characteristics and architecture.

Results of five remote and two in situ techniques agree (with a few exceptions) within 95% confidence level uncertainties and generally within 15% above 20 km. Weighted mean profiles, which best represent conditions during the campaign, are used as a comparison standard. Accuracies of experiments indicated by BIC generally confirm estimated uncertainties for ECC sondes, UV photometry, and microwave emission experiments, are somewhat better for far IR emission and IR absorption experiments, and are somewhat worse for IR emission and solar UV absorption experiments.

AN - 15739257; 2361743 AB - The purpose of this study was to evaluate the National Aeronautics and Space Administration (NASA) Space Shuttle Launch Entry Suit (LES) and raft for 24 h of protection against cold water immersion. Two configurations, the LES and the LES with raft (Navy LRU-18/U with NASA spray shield) were evaluated for anti-exposure protection. Conditions were selected to simulate worst case water and air temperatures along projected Space Shuttle ground tracks; i.e., water temperatures = 4.4 degree C (40 degree F), air temperature = 5.6 degree C (42 degree F), 1 foot waves (chop), and constant spray. Four males, 31-44 years of age, and one 32-year-old female, were studied once in each configuration. Trials with and without a raft were scheduled for up to 24 and 6 h, respectively. Mean LES trial durations were 150 plus or minus 9 min and final rectal temperature (T sub(re), f) = 36.5 plus or minus 0.3 degree C. Mean LES with raft (LES/r) trial durations were 398 plus or minus 126 min and final rectal temperature (T sub(re), f) = 35.6 plus or minus 0.4 degree C. LES and LES/r trials were terminated for reaching T sub(re) = 35.0 degree C or subject-requested termination due to discomfort.

Accuracy and reproducibility of this apparatus compared with the conventional Gram staining method were evaluated by using gram-negative and gram-positive controls and different species of bacteria grown in pure cultures. A subsequent study was designed to assess the performance of the GSA with actual specimens. A set of 60 human and environmental specimens was evaluated with the GSA and the conventional Gram staining procedure. Data obtained from these studies indicated that the GSA will provide the Gram staining capability needed for the microgravity environment of space.

AN - 15632243; 2283586 AB - Large areas of elevated phytoplankton pigment concentrations were observed using CZCS satellite data in the Weddell Sea marginal ice zone and adjacent regions during the austral summer-autumn transition. Phytoplankton blooms about 200 km wide and extending several hundred kilometers were observed. higher pigment values in the south than in the north indicate that irradiance is not the only factor controlling spatial distributions. A time series in Marguerite Bay also shows a bloom for at least 12 days and significant effects on spatial distribution of the phytoplankton due to ocean and sea ice movement. An unusual pattern of sea ice formation in the Weddell Sea was also observed near the Greenwich meridian. Turbulent oceanic and atmospheric forcings during the development of sea ice in the region may account for the low pigment concentrations observed adjacent to the area.

AN - 15612562; 2248904 AB - Microbial mats have descended from perhaps the oldest and most widespread biological communities known. Mats harbor microbes that are crucial for studies of bacterial phylogeny and physiology. They illustrate how several oxygen-sensitive biochemical processes have adapted to oxygen, and they show how life adapted to dry land long before the rise of plants. The search for the earliest grazing protists and metazoa in stromatolites is aided by observations of mats: in them, organic compounds characteristic of ancient photosynthetic protists can be identified. Recent mat studies suggest that the super(13)C/ super(12)C increase observed over geological time in stromatolitic organic matter was driven at least in part by a long-term decline in atmospheric carbon dioxide levels.

AN - 15601185; 2240317 AB - Modern high-speed propeller (advanced turboprop) aircraft are expected to operate on 50 to 60% less fuel than the 1980 vintage turbofan fleet while matching the flight speed and performance of those aircraft. Counterrotation turboprop engines offer additional fuel savings by means of upstream propeller swirl recovery. This paper presents acoustic sideline results for a full-scale counterrotation turboprop engine (General Electric "UDF" engine) at cruise conditions. The engine was installed on a Boeing 727 aircraft in place of the right-side turbofan engine. Acoustic data were taken from an instrumented Learjet chase plane. Sideline acoustic results are presented for 0.50 and 0.72 Mach cruise conditions. Model propeller data taken in a windtunnel were adjusted to flight acquisition conditions and were in general agreement with the flight results.

AN - 15568450; 2212907 AB - The vegetation and avian communities of a site consisting of oak/palmetto scrub and disturbed oak scrub were characterized. Nearly half of the oak/palmetto scrub was intentionally burned midway through the study. The prescribed fire altered avian community composition for at least 6 months in areas where nearly all the vegetation burned. Twenty years after clearing of an area of oak/palmetto scrub, the regenerated oak-scrub habitat differed from adjacent oak/palmetto scrub in having more bare ground (15.5 vs. 0.8%), a taller shrub layer (272 vs. 161 cm) composed primarily of oak species without saw palmetto and more herbaceous species (11 vs. 3). Compared with oak/palmetto scrub, disturbed oak scrub had more breeding bird species that were abundant enough to allow density estimation (8 vs. 4) and supported a higher density of the Florida scrub jay (Aphelocoma coerulescens coerulescens ), a threatened subspecies.

AN - 15489653; 2221485 AB - The rise in atmospheric chlorine levels caused by the emission of chlorofluorocarbons and other halocarbons is thought to be the main cause of the appearance of the Antarctic ozone "hole" in the late 1970s, and the more modest ozone depletion observed over parts of the Northern Hemisphere. Atmospheric bromine, also associated with halocarbon emissions, is believed to contribute to ozone depletion. Over the next decade, further increases in these compounds are inevitable. Model calculations show that by the end of the next century, atmospheric chlorine and bromine levels may return to those prevalent before the onset of the ozone hole, but only if more stringent regulations are applied to halocarbon production than those currently proposed.

AN - 15475032; 2210095 AB - We have compared numerically calculated soluble species residence times with several analytic residence time models. The numerical results are dependent on whether randomly or periodically distributed precipitation events are assumed. A preferred time of occurrence for rain, such as morning or afternoon, influences the computed HNO sub(3) residence time for precipitation cycle times (wet plus dry period) of about a day, but exerts less influence as the cycle time increases. An analytic residence time model developed by Rodhe and Grandell is found to agree well with residence times computed for randomly distributed precipitation events while a model developed by Giorgi and Chameides is more suitable for periodic rain. The present numerical calculations resolve an apparent ambiguity in HNO sub(3) residence times computed in earlier numerical studies.

The influence of canopy closure, understory vegetation and background reflectance. AN - 15466846; 2198374 AB - The relationship between the leaf area index (LAI) of temperate coniferous forests in the western United States and Thematic Mapper (TM) data corrected for atmospheric effects and Sun-surface-sensor geometry was influenced by canopy closure, understory vegetation and background reflectance. Strong inverse curvilinear relationships were observed between coniferous forest LAI and both TM bands 3 (0 multiplied by 63-0 multiplied by 69 mu m) and 5 (1 multiplied by 55-1 multiplied by 75 mu m). The inverse relationships are explained by increased reflectance of understory vegetation and background in open stands of lower LAI and decreased reflectance of the overstory in closed canopy stands with higher LAI.
