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.
