AN - 85312712; pmid-10080866 AB - This report describes the development and evaluation of mathematical models for predicting human performance from discrete wavelet transforms (DWT) of event-related potentials (ERP) elicited by task-relevant stimuli. The DWT was compared to principal components analysis (PCA) for representation of ERPs in linear regression and neural network models developed to predict a composite measure of human signal detection performance. Linear regression models based on coefficients of the decimated DWT predicted signal detection performance with half as many free parameters as comparable models based on PCA scores. In addition, the DWT-based models were more resistant to model degradation due to over-fitting than PCA-based models. Feed-forward neural networks were trained using the backpropagation algorithm to predict signal detection performance based on raw ERPs, PCA scores, or high-power coefficients of the DWT. Neural networks based on high-power DWT coefficients trained with fewer iterations, generalized to new data better, and were more resistant to overfitting than networks based on raw ERPs. Networks based on PCA scores did not generalize to new data as well as either the DWT network or the raw ERP network. The results show that wavelet expansions represent the ERP efficiently and extract behaviorally important features for use in linear regression or neural network models of human performance. The efficiency of the DWT is discussed in terms of its decorrelation and energy compaction properties. In addition, the DWT models provided evidence that a pattern of low-frequency activity (1 to 3.5 Hz) occurring at specific times and scalp locations is a reliable correlate of human signal detection performance.

AN - 70856616; 11542270 AB - Lactuca sativa cv. Baijianye seedlings do not normally produce lateral roots, but removal of the root tip or application of auxin, especially indole-butyric acid, triggered the formation of lateral roots. Primordia initiated within 9 h and were fully developed after 24 h by activating the pericycle cells opposite the xylem pole. The pericycle cells divided asymmetrically into short and long cells. The short cells divided further to form primordia. The effect of root tip removal and auxin application was reversed by 6-benzylaminopurine at concentrations >10(-8) M. The cytokinin oxidase inhibitor N1-(2chloro4pyridyl)-N2-phenylurea also suppressed auxin-induced lateral rooting. The elongation of primary roots was promoted by L-alpha-(2-aminoethoxyvinyl) glycine and silver ions, but only the latter enhanced elongation of lateral roots. The data indicate that the induction of lateral roots is controlled by basipetally moving cytokinin and acropetally moving auxin. Lateral roots appear to not produce ethylene.

AN - 70851472; 11541545 AB - In preparation for future Lunar/Mars habitats, a food system is being developed at NASA-JSC to provide Advanced Life Support for long-duration missions. As much as 90% of the food consumed on these missions is expected to be grown, processed, and prepared in space. Conversion of crops to edible foods will require extensive food processing within the closed environment of the Bioregenerative Planetary Life Support System Test Complex (BIO-Plex). Identification of hazards and critical control points associated with water recycling, biomass management, use of multifunctional equipment, and possible concentration of toxic substances in the closed system is essential for the development of safe food processing techniques and equipment. A food safety analysis, using a Hazard Analysis Critical Control Point (HACCP) approach, was conducted to identify potential hazards and critical control points during food processing of BIO-Plex-produced lettuce and wheat.

Biological and closed-loop ecosystem considerations. AN - 70850627; 11541762 AB - The Martian surface is exposed to both UVC radiation (<280 nm) and higher doses of UVB (280-315 nm) compared to the surface of the Earth. Terrestrial organisms have not evolved to cope with such high levels of UVC and UVB and thus any attempts to introduce organisms to Mars, particularly in closed-loop life support systems that use ambient sunlight, must address this problem. Here we examine the UV radiation environment of Mars with respect to biological systems. Action spectra and UV surface fluxes are used to estimate the UV stress that both DNA and chloroplasts would experience. From this vantage point it is possible to consider appropriate measures to address the problem of the Martian UV environment for future long term human exploration and settlement strategies. Some prospects for improving the UV tolerance of organisms are also discussed. Existing artificial ecosystems such as Biosphere 2 can provide some insights into design strategies pertinent to high UV environments. Some prospects for improving the UV tolerance of organisms are also discussed. The data also have implications for the establishment of closed-loop ecosystems using natural sunlight on the lunar surface and elsewhere in the Solar System.

AN - 69518544; 11963955 AB - A new type of in situ, remotely monitored magnetism-based sensor is presented that is comprised of an array of magnetically soft, magnetostatically-coupled ferromagnetic thin-film elements or particles combined with a chemically responsive material that swells or shrinks in response to the analyte of interest. As the chemically responsive material changes size the distance between the ferromagnetic elements changes, altering the inter-element magnetostatic coupling. This in turn changes the coercive force of the sensor, the amplitude of the voltage spikes detected in nearby pick-up coils upon magnetization reversal and the number of higher-order harmonics generated by the flux reversal. Since the sensor is monitored through changes in magnetic flux, no physical connections such as wires or cables are needed to obtain sensor information, nor is line of sight alignment required as with laser telemetry; the sensors can be detected from within sealed, opaque or thin metallic enclosures.

AN - 69511515; 11543269 AB - Membrane separation of gases is governed by the permeability of each species across the membrane. The ratio of permeabilities yields the selectivity. Use of certain organic carriers in facilitated transport membranes and the CO2 converting enzyme carbonic anhydrase (CA) in proteic and facilitated transport membranes allows a dramatic increase in CO2 selectivity over other gases. CA has a low Km (9 mM), which we predicted would allow it to scavenge CO2 to very low partial pressures. Our goal was to determine if CA could remove CO2 from an environment at levels of 0.1% or less. Prior measurements of CO2 transport across thin supported liquid membranes showed that addition of CA enhanced CO2 flux by 3- to 100-fold. Proteic films use bifunctional reagents (e.g., glutaraldehyde) to cross-link the enzyme forming a gel. Bovine serum albumin (BSA) is often added for structural stability. Using such a preparation we examined the ability of proteic films to improve CO2 selectivity and to scavenge CO2 from a mixed gas stream. Proof-of-concept results, measured by mass spectrometry, showed a fivefold improvement in CO2 capture rate with maximal improvement at CO2 values of 1% partial pressure difference in the presence of 0 atm absolute difference. At 0.1% CO2 the membrane exhibited a 76% improvement over controls. At 0.3% CO2 the improvement is about threefold. CA proteic membranes exhibit selectivity for CO2 over oxygen and nitrogen in excess of three orders of magnitude. A CA-based proteic or facilitated transport membrane should readily achieve CO2 partial pressures of 0.05% under CELSS conditions. In addition to proteic membranes we are exploring direct immobilization of engineered CA to ultra-high-permeability teflon membranes. Site-directed mutagenesis was used to add functional groups while retaining full enzymatic activity. These results provide a basis for development of far more efficient CO2 capture proteic and facilitated transport membranes with increased selectivity to values closer to 100-fold at 1% CO2. The result will be CO2 selectivity at 0.1% on the order of 400-fold. These results exceed those obtained with other technologies.

Comparative evaluation of process design alternatives. AN - 69510896; 11542677 AB - As a candidate technology for treating solid wastes and recovering resources in bioregenerative Advanced Life Support, composting potentially offers such advantages as compactness, low mass, near ambient reactor temperatures and pressures, reliability, flexibility, simplicity, and forgiveness of operational error or neglect. Importantly, the interactions among the physical, chemical, and biological factors that govern composting system behavior are well understood. This article comparatively evaluates five Generic Systems that describe the basic alternatives to composting facility design and control. These are: 1) passive aeration; 2) passive aeration abetted by mechanical agitation; 3) forced aeration--O2 feedback control; 4) forced aeration--temperature feedback control; 5) forced aeration--integrated O2 and temperature feedback control. Each of the five has a distinctive pattern of behavior and process performance characteristics. Only Systems 4 and 5 are judged to be viable candidates for ALS on alien worlds, though which is better suited in this application is yet to be determined.

AN - 69509504; 11712548 AB - Cabin emergent depressurization (CED) may occur in spacecraft during manned space flight. The purpose of this paper was to study the combined effects of simulated weightlessness (SW) and CED factors on humans and animals. It was found that the amplitude of T wave of human electrocardiograms (ECG) significantly decreased in bed rest and hypoxia compared with the control condition (P<0.05), and that suspension with pure O2 induced severer edema in the lungs of rats than that in only a pure O2 environment. SW and pure O2 caused middle ear congestion and decreased the barofunction during pressure changes. These results indicate that human response to CED factors become more serious under SW because of the blood redistribution. c1999 COSPAR. Published by Elsevier Science Ltd.

AN - 69509045; 11542538 AB - A simplified closed system consisting of a plant growth chamber coupled to a decomposition chamber was used to study carbon exchange dynamics. The CO2 produced via the decomposition of wheat straw was used for photosynthetic carbon uptake by wheat plants. The atmosphere of the two chambers was connected through a circuit of known flow rate. Thus, monitoring the CO2 concentrations in both compartments allowed measurement of the carbon exchange between the chambers, and estimation of the rate of respiration processes in the decomposition chamber and photosynthetic rate in the producer chamber. The objective for CELSS research was to simulate a system where a compartment producing food via photosynthesis, would be supplied by CO2 produced from respiration processes. The decomposition of biomass by the decomposer simulated both the metabolism of a crew and the result of a recycling system for inedible biomass. Concerning terrestrial ecosystems, the objective was to study organic matter decomposition in soil and other processes related to permanent grasslands.

This study examined leaching rates and total leachability of Triticum aestivum L. Yecora Rojo residue. Total biomass reduction and phosphate concentration in the leachate were tested as a function of particle size, leaching time of solid, temperature, and sonication versus mechanical agitation. For modeling purposes, phosphate rate constants were determined experimentally via batch testing on 25-mm biomass. Simulation models were written to predict the effect of liquid flow rate on phosphate leaching in concurrent and countercurrent reactors.

AN - 69504297; 11543265 AB - Multivariable polynomial regression (MPR) was used to model plant motion time-series and nutrient recovery data for Advanced Life Support (ALS). MPR has capabilities similar to neural network models in terms of ability to fit multiple-input single-output nonlinear data. It has advantages over neural networks including: reduced overfitting, produces models that are more tractable for optimization, sensitivity analysis, and prediction of confidence intervals. MPR was used to produce nonlinear polynomial time-series models predicting plant projected canopy area versus time and temperature. Temperature was found to not have a statistically significant effect. Models were developed to relate rate and extent of nutrient recovery to treatment parameters, including temperature and use of heat pretreatment or nutrient supplementation. These applications demonstrate MPR's capability to fill "gaps" in an integrated model of ALS. Fundamental models should be used whenever available. However, some components may require empirical modeling. Furthermore, even fundamental models often have empirical constituents. MPR models are proposed to satisfy these needs.

Temperature feedback control with top-wise introduction of waste material and air. AN - 69502820; 11542678 AB - Whereas Earth-based composting reactors that effectively control the process are batch operations with bottom-to-top airflow, in extraterrestrial application both the fresh waste and the air need to be introduced from above. Stabilized compost and used air would exit below. This materials flow pattern permits the addition of waste whenever generated, obviating the need for multiple reactors, and the incorporation of a commode in the lid. Top loading in turn dictates top-down aeration, so that the most actively decomposing material (greatest need for heat removal and O2 replenishment) is first encountered. This novel material and aeration pattern was tested in conjunction with temperature feedback process control. Reactor characteristics were: working, volume, 0.15 m3; charge, 2 kg dry biomass per day (comparable to a 3-4 person self-sufficient bioregenerative habitat); retention time, 7 days. Judging from temperature profile, O2 level, air usage, pressure head loss, moisture, and odor, the system was effectively controlled over a 35-day period. Dry matter disappearance averaged 25% (10-42%). The compost product was substantially, though not completely, stabilized. This demonstrates the compatibility of top-wise introduction of waste and air with temperature feedback process control.

AN - 69501631; 11542686 AB - The US Navy supports deep diving operations with a variety of mixed-gas life support systems. A systems engineering study was conducted for the Naval Experimental Dive Unit (Panama City, FL) to develop a concept design for an advanced dive monitoring system. The monitoring system is intended primarily to enhance diver safety and secondarily to support diving medicine research. Distinct monitoring categories of diver physiology, life support system, and environment are integrated in the monitoring system. A system concept is proposed that accommodates real-time and quantitative measurements, noninvasive physiological monitoring, and a flexible and expandable implementation architecture. Human factors and ergonomic design considerations have been emphasized to assure that there is no impact on the diver's primary mission. The Navy has accepted the resultant system requirements and the basic design concept. A number of monitoring components have been implemented and successfully support deep diving operations.

AN - 69499330; 11542535 AB - The greenhouse environment is a challenging artificial ecosystem in which it is possible to study selected plant/insect interaction in a controlled environment. Due to a combination of "direct" and "indirect" effects of CO2 enrichment on plant photosynthesis and plant development, canopy productivity is generally increased. In this paper, we discuss the effects of daytime and nighttime CO2 enrichment protocols on gas exchange of pepper plants (Capsicum annuum L, cv Cubico) grown in controlled environments. In addition, we present the effects of thrips, a common Insect pest, on the photosynthetic and respiratory activity of these plant canopies. Carbon dioxide has diverse effects on the physiology and mortality of insects. However, our data indicate that thrips and whiteflies, at least, are not killed "directly" by CO2 levels used to enhance photosynthesis and plant growth. Together the data suggest that the insect population is affected "indirectly" by CO2 and that the primary effect of CO2 is via its effects on plant metabolism.

The results show that the primary effects on C isotopic fractionation of methanotrophic bacteria are the consequence of the form of methane monooxygenase expressed by the cells, the mechanism for assimilation of cell-C and the type of cellular physiology. Growth T influences the relative abundance of specific hopane biomarkers but has no effect on the relative C isotopic composition of the various hopanoids or on fatty acids. Growth by methane oxidation results in C isotopic depletion for specific biomarkers which may indicate methanotrophy.

The two primary characteristics that make remote sensing a potentially powerful tool are its ability to provide spatial information and to measure directly state variables such as surface temperature and soil moisture. A hypothesis is presented, with remote sensing examples, that many hydrologic processes display a unique signature that is detectable with microwave remote sensing. These signatures are in the form of the spatial and temporal distributions of surface soil moisture. The specific hydrologic processes that may be identified include groundwater recharge and discharge zones, storm runoff contributing areas and assessment of non-point source pollution, regions of potential and less than potential evapotranspiration, and information about the hydrologic properties of soils. An argument is made that such estimates may be more useful and physically more meaningful for use in hydrologic models than laboratory-derived data or statistical estimates. The reasoning behind this argument is that what is being observed is a signature of how the soil hydrology is reacting to atmospheric and drainage forcing that reflects the physical properties of the soils, and more importantly, their location within a field and with respect to topography and drainage patterns.

Biofilms consist of colonies of different types of bacteria (among other microorganisms) embedded in a layer of microbially-produced mucopolysaccharides, as well as trapped detrital and precipitated minerals. We present examples of mineralised biofilms ranging in age from the early Archean to the present to demonstrate the hitherto unappreciated importance of this phenomenon in the rock record. Bacteria mediate mineral formation by changing the physico-chemical conditions in their immediate environment and by providing attractive nucleation sites as organic templates for minerals. In addition, their extracellular polymeric secretions (EPS) can act as organic templates for mineral nucleation. It appears that mineralised biofilms in the geological fossil record may be more common in the rock record than the preservation of mineralised bacteria. We are investigating the processes in which bacteria and EPS serve as organic templates and catalysts for mineral nucleation. Dissolved ions chelate to active groups on the surface of, and within, the organic template. Nucleation and growth of precipitated substances on or within bacteria or EPS may form amorphous masses or well crystallised minerals, or a combination of both. We illustrate the mineralisation of bacteria and bacterial biofilms using both experimental studies and examples from the rock record: silicified bacteria and biofilms from the Early Archean Barberton greenstone belt in South Africa and the Pilbara block, Australia; phosphatised bacteria from the Early Eocene Messel Formation in S. Germany; silicified biofilms and bacteria from Early Miocene, South Atlantic, deep-sea sediments; silicified and calcified bacteria and biofilms from the hot springs, e.g. Yellowstone, Wyoming and New Mexico.

We have found evidence of bacterially-mediated precipitation in 4 samples from the dark zone of the upper section of Hidden Cave, located in the Guadalupe Mountains, NM. Our samples, which are moderately-sized fingers for this particular pool, range from 1 to 5 cm in diameter and up to 20 cm long. The fingers have a rough surface with protrusions up to 1 cm in diameter and up to 5 mm high. However, on 2 samples this surface is obscured by cave popcorn. The core of each finger is micritic calcite, usually with dark brown 30-50 mu m spherical lumps. The rest of the fingers are composed of alternating layers of dark micritic calcite and clear bladed to dogtooth calcite spar. Micritic layers are up to 3 mm thick and vaguely laminated or lumpy to bushy with dark 30-100 mu m cores. The spar layers are irregular and composed of crystals 50-100 mu m wide and up to 2 mm long, often radiating out from dense micritic cores. Elongated inclusions are abundant. The lumpy micrite strongly resembles both pelmicritic marine cement and travertine where bacteria involvement has been previously documented. The laminated fabrics are reminiscent of algal laminations but algae are not an option in this totally dark location. This study documents a new environment for bacterially-mediated precipitation of calcitic speleothems in a cave setting beyond the twilight zone and has implications for similar fabrics in marine limestones.

Profiles from Science Phasing Orbits 1 & 2 led to discovery of a 450 km wide basin in Arabia as large and as deep as the Cassini impact structure 1000 km to the SW. This Phison Rupes Basin (GRL 26, 1657-1660, 1999) was not previously recognized because it has almost no structural expression visible in image data. Profile data also show bowl-like topography for a 550 km wide structure on the dichotomy boundary in western Tempe Terra. Gridded data reveal numerous circular lows in the highlands with negative relief of several hundred meters but not associated with obvious impact craters. Our study suggests several may be ancient impact basins. Particularly interesting is an 800 m deep depression more than 400 km wide just east of Huygens, in an area dominated by smooth plains and partially buried craters. A circular depression 350-700 m deep and more than 300 km wide is found 800 km west of Cassini and encloses an area of ridged plains. In both cases there is little visible evidence of a rim-like structure. Also, an 800 km wide, 1 km deep basin may overlie the S rim of Hellas and enclose Malea Planum. We suggest that the total population of small to moderate size (300-1000 km) impact basins on Mars may be much larger than previously thought.

ALERT's primary goal is to improve introductory-level Earth Science courses, particularly those that serve future K-12 teachers. Because the CSU prepares more than 70% of the teachers educated in California, its faculty is in a unique position to increase awareness and understanding of the Earth among thousands of pre-service teachers and the children who will be their students. Project ALERT provides a powerful paradigm for bringing NASA information and technology into teacher education classrooms and for lending CSU expertise to the design of NASA's educational products and policies. Key elements of Project ALERT include 1) enhanced communication and collaboration between scientists and science educators at participating CSU campuses, 2) summer faculty fellowships for CSU earth scientists and science educators to work at ARC and JPL, 3) semester and quarter faculty "release time" for incorporation of summer experiences at NASA Centers into classroom practice, and 4) collaboration with other NASA projects such as ESSE (Earth System Science Education) and NOVA (NASA Opportunities for Visionary Academics). On-going and future outcomes of Project ALERT include new and modified courses and earth science modules incorporating NASA imagery and data, an ALERT digital library, and new methods to package and handle NASA information for use by educators.

It began with educational specialists traveling in "space mobiles" from school to school to present "golly gee whiz" shows in auditoriums to student assemblies. The students were given lots of facts about rockets, space, and the technology necessary for successful ventures into space and in experimental aircraft. But teachers wanted more. The enthusiasm instilled in students often was short-lived because only memories were left behind. The "space mobile" program, however, evolved into educational experiences for teachers and is operationalized by the current Aerospace Educational Services Project (AESP) (http://www. okstate.edu/aesp/AESP.html). The educational specialists (master teachers holding advanced degrees in science, mathematics, and technology education) are stationed at ten NASA facilities and travel within states to deliver workshops and materials to teachers. During the summer, the specialists train teachers at NASA facilities in curricular activities that involve NASA aero-space technology, human exploration and development of space, space science, remote sensing, and earth processes. The educational division of NASA publishes many curricular materials which form the basis of enhancing the curricula and contribute to a high rate of classroom adoption. These materials, including posters, videos, and K-12 activities, are provided free through Spacelink (http://spacelink.nasa.gov ) and Education Resource Centers (http://education.nasa.gov/educators.html). By turning students onto science, technology, and mathematics, NASA plants the seeds for careers in science and accentuates the vast spectrum of opportunities available in NASA. AESP has proven time and again that NASA is promoting educational excellence by involving the educational community to create learning opportunities, inspire America's students, and enlighten inquisitive minds.

This process would also produce MgO and CaO from breakdown of the iron-magnesian carbonate. In an effort to further constrain conditions of carbonate formation in ALH84001 and the effects of shock metamorphism experienced by the meteorite both during transport to the surface of Mars and ejection from the planet, carbonate globules and surrounding orthopyroxene were examined for oxides and traces of amorphous phases by Raman Spectroscopy. Raman maps of three carbonates were produced. In addition to the previously described zoned carbonate (siderite-magnesite-ankerite solid solutions) pyroxene glass identified by broad Raman bands centered at about 480 and 700 cm-1 was detected in a strip 7-10 mu m wide between the outer rim magnesite and inner carbonate core. Pyroxene glass is also found dispersed within the core carbonate. Magnetite was detected in the outer rim and also found dispersed within the core carbonate. MgO and CaO produce strong and distinct Raman signals. If present in ALH84001, even very small amounts would be detected. CaO and MgO were not detected in the carbonates making it unlikely that the magnetites in ALH84001 were formed by thermal or shock decomposition of the carbonate while creating voids by devolitilization of CO (sub 2) . Recent experimental shock studies on carbonate prove its stability to approximately 60 GPa, well in excess of the approximately 40 GPa peak pressures indicated by other shock features in ALH84001 [Bell, 1998; Bell et al., 1999].

During a ten day period in 1998, Assateague Island MD, VA was severely impacted by two winter storms with offshore significant wave heights exceeding 7 m. The island was surveyed pre-and post-storm using NASA's Airborne Topographic Mapper (ATM), a scanning airborne laser altimeter. Along a 20 km reach of the barrier island, different impacts occurred including net dune erosion with no overwash, classic berm overwash with net migration landward and complete inundation where new inlets formed. By examining the relationships between calculated wave runup and the vertical dimensions of the coast, each type of impact can be categorized. The new scale should prove useful in parameterizing storm impacts both between and along barrier islands of variable relief. JF - Coastal Sediments ... : Proceedings of the ...

Fullerenes (C60 and C70) have been detected in shock-produced breccias (Onaping Formation) associated with the 1. 85 billion-year-old Sudbury Impact Crater and in clay sediments within the 65 million-year-old Cretaceous/Tertiary boundary (KTB). In an effort to determine the origin of the Sudbury fullerenes, we searched for noble gases trapped inside the fullerene molecules (Saunders et al., Science 259, p. 1428, 1993). The result of this study revealed that the Sudbury fullerenes contained trapped 3He/4He ratios ( approximately 5.5X10 (super -4) ) that are similar to those found in meteorites and some interplanetary dust particles (IDPs) (Becker et al., Science 272, p. 249, 1996). Measurements of He in a continental KTB clay from the Raton Basin, Colorado, revealed a clear ET helium signal with 3He/4He ratios about 100x the air ratio. The concentration of 3He in Raton fullerenes ( approximately 5 micrograms)is within a factor of 2 of the He in the Sudbury fullerenes ( approximately 100 micrograms). A marine KTB residue from Stevns Klint, Denmark, revealed a 3He/4He ratio several 1000x above air! The concentration of 3He in Stevns Klint ( approximately 8 micrograms sample) is some 4x higher than the Sudbury fullerenes. We attribute the anomalously high 3He/4He ratios and high 3He concentration for the Stevns Klint residue to the abundance and stability of higher fullerenes (C100 to C250) in the residue. We have begun investigating the possibility of fullerenes in sediments from the 250 myr old Permian/Triassic boundary layer (PTB). Preliminary data indicate that fullerenes (C60 to C200) are present in PTB sediments from China (Meishan) and Japan (Sasayama). Confirmation of ET helium in the P/T fullerenes could have broad implications concerning the importance of impact events in contributing to the changes observed in the biostratigraphic record throughout geologic time.

Key features in the Andean foreland are nested megafans, hundreds of km in radius (10 (super 4) -10 (super 5) km (super 2) ), transverse to the mountain front, built by rivers sourced in the orogenic belt. Because of their great extent (compared with alluvial fans and floodplains), large areas of megafans remain unaffected for long periods (10 (super 3) -10 (super 5) y) by fluvial dynamics such as avulsion and meander migration. Morphogenetic stasis combined with stream behavior, suggests mechanisms of potential interest to aquatic evolutionary biology. A Avulsion. Rivers avulse into new radial positions, generating new alluvial tracts (or re-occupying old tracts) across megafan surfaces. This serves alternately to sever, and then to re-establish connections between trains of oxbow lakes and swamplands in a specific alluvial tract. Fans which straddle major divides play a special role: remotely-sensed evidence (Space Shuttle photos) of apex avulsion of the Parapeti R. suggests that this river can link aquatic fauna of the Amazon and Parana basins. Similar examples are known from other continents. B Aridity. Connections between megafan (and other) streams and foreland axial rivers can be severed periodically with the onset of aridity. Today the Parapeti, Pilcomayo, and Dulce Rivers all fail to reach axial rivers (Paraguay-Parana), becoming potential islands of speciation. Such islands achieve greater complexity when streams on neighboring megafans meet one another by avulsing simultaneously into the common depression between the fans. C Autochthonous stream network evolution. After trunk stream avulsion, streams sourced on megafans gradually become better integrated, as documented on Indian megafans. This implies the reconnection of at least some lake and swamp habitats isolated when the main stream avulsed away. D Stream invasion. Counter-intuitively, streams rising outside the confines of a megafan can establish new courses across the markedly flat topography of the megafan (as in northern India), thereby reconnecting isolated lakes and swamps.

At present the database stores a wide range of information including ecology, socio-economics, threats and management on over 8500 coral reefs. A new interface is being developed which will transform ReefBase into an up to date Geographic Information System (GIS). ReefBase is the official database of the Global Coral Reef Monitoring Network (GCRMN) and is involved in numerous international coral reef related activities and collaborations. One of these collaborations involves the Office of Earth Sciences at NASA's Johnson Space Center. It comprises combined efforts to search, select and scan photographs of coral reef areas from the NASA Space Shuttle Earth Observations Photography Database. This database contains over 300 000 photographs taken by Space Shuttle astronauts. An initial set of 750 high resolution photograph scans are being georeferenced and spectrally corrected for inclusion in ReefBase. These images will serve as photographic basemaps in the new ReefBase GIS interface, on which data from ReefBase can be overlaid. The Space Shuttle photographs provide an excellent visual tool for displaying coral reef related information. Furthermore, once incorporated into a Geographic Information System, these images can be of great value to research efforts aimed at establishing much needed estimates of coral reef locations and extent on national, regional and global scales.

Japan's contribution in this area began with the post flight impact analysis of the Space Flyer Unit (SFU) satellite which was returned to Earth in 1996 after 10-month exposure in space. Despite a decade later than similar efforts first conducted in the USA and Europe, it resulted in a record of over 700 hypervelocity impact signatures, which now forms the nation's first database of real space impacts being open to public in the Internet. Together with laboratory impact tests, both morphological and elemental analyses of the impact craters yielded new insights of the meteoroid to debris ratio as well as flux variation compared with the previous spacecraft. The next step was a passive aerogel exposure in the STS-85 shuttle mission in 1997. No hypervelocity impact was found there but its experience has been incorporated for designing a microparticle collector to be on-board the Japan Experiment Module-Exposed Facility of the International Space Station. All of such "passive" collection of micro-impact features, however, still leave the significant uncertainty in the quest of their origins. Therefore an aerogel-based "hybrid" dust collector and detector (HD-CAD) is currently under the development. It measures time of impact and deduces impactors' orbital and physical parameters by detecting impact flash while still capturing them intact. The system is suitable for both (1) sample return missions in LEO as well as to parent bodies of meteoroids, i.e., comets and asteroids, and (2) one-way mission to where the thermal and plasma environment is such that impact induced plasma detectors may suffer from significant noise, e.g., a Mercury orbiter and a solar probe. Together with unambiguous dust samples from a comet by STARDUST and an asteroid by MUSES-C as references, the HD-CAD in the LEO will be able to deduce the accretion rates of the cometary and asteroidal dust grains on the Earth.

ISS will orbit the Earth between N51.6 degrees and S51.6 degrees latitude, covering 75% of the Earth's surface. The same point will be overflown approximately every 3 days, with similar lighting conditions approximately every 90 days. The nadir research window in the U. S. Laboratory has a 51-mm diameter clear aperture, and is constructed from 3 panes of high quality fused silica. The optical performance of this window is 1/10th wavelength peak-to-valley over a 15. 2 mm diameter (wavelength = 632. 8 nm) such that it will support up to a 30. 5 cm diameter optic. The Window Observational Research Facility (WORF) will provide a stable platform for payloads that will utilize the International Space Station (ISS) U. S. Laboratory nadir research window. This facility, which will be built around a standard Express payload Rack, will include mounting interfaces for up to two payloads, and access to the standard suite of U. S. Laboratory utilities, including power, data, moderate temperature control and video downlink. In addition, the facility allows crew members to conduct Earth science activities, and has attach points for payload mounts and two adjustable brackets for crew operated still cameras and camcorders. Payloads will be able to choose between a number of operational modes, ranging from crew operated to completely autonomous. The WORF will be launched on Utilization Flight UF-2 in May of 2001, and will be one of the first research payloads installed in the U. S. Laboratory on ISS.

The SRL flights collected complementary, multi-seasonal data sets from around the planet using a combination of space-based sensors: an advanced synthetic aperture radar, a carbon monoxide (CO) IR sounder, and tens of thousands of visible-range images from the cameras of the astronauts. The ISS will offer similar opportunities for synergistic Earth observations from the dedicated Laboratory window and external payload sites on the station's truss. The SRL-1 and 2 missions, flown in April and October 1994, produced dramatic geological observations that are illustrative of those possible from ISS. Some of the most interesting were volcano observations conducted as part of the U. N. 's Decade Volcano research program. In April 1994, the Shuttle Imaging Radar-C (SIR-C) and X-band Synthetic Aperture Radar (X-SAR) captured images of the Philippines' Mt. Pinatubo 3 years after its powerful eruption, while the crew photographed the mountain with a variety of film/lens combinations. These visible images documented the extensive ash flows blanketing the summit, while the radar images (at X-, C-, and L-band) mapped the movement of the resulting lahars; their destructive progress down the volcano was easily traced 6 months later on SRL-2. The second SRL mission had the good fortune to document the eruption of Asia's tallest volcano Klyuchevskaya in September 1994. This Kamchatkan volcano and its neighbors were already targeted in the mission's science plan, but the launch-day eruption produced a unique opportunity to observe the course of Klyuchevskaya's largest outburst in 40 years. Video and still images from Endeavour's cockpit documented the intensity of the eruption and the 15-km-high ash and dust plume over the course of the next week. More importantly, SRL's multi-frequency radar penetrated the plume and an intervening snowstorm to reveal the source and progress of mudflows downslope. ISS will offer geologists many similar, more exciting opportunities over the next two decades. Using crew photography, window-mounted sensors, and truss-mounted experiments, the new space station will open a versatile window for geologists studying the Earth from space.

S. Space Program has supported Earth photography by astronauts from spacecraft since the early 1960s, logging almost 2000 days in space by 288 astronauts. Over the years, our program of managing the imagery of the Earth's surface by astronaut crews has grown substantially: the office maintains a large database containing both images and the catalog information on nearly 400,000 images of Earth, providing global coverage and spanning 35 years. Most of these data (images and metadata) can be accessed by scientists and educators around the world through the NASA-Johnson Space Center Office of Earth Sciences database at http://eol.jsc.nasa.gov. In addition, users now have access to the global information networks and database technologies to analyze and interpret single images, historical images or large data sets of images of Earth, expanding the potential for application of the image database to real-world problems and educational curricula. These data can be tapped to a) piece together time series like changes in landuse, regional hydrology networks or coastlines; b) examine events on different time scales (from hours to decades); and c) provide unifying data for interdisciplinary Earth science studies.Furthermore, our scientific perspective acquired through the analysis of 35 years of astronaut photography of Earth allows us to identify some of the truly unusual or significant events on the Earth's surface, like the largest smoke palls or rapid changes in regional water supplies. Within this context, new astronaut observations are improving our understanding of the sizes and frequencies of global processes like floods, droughts, human landuse, dust storms, biomass burning, smog production, plankton blooms, and more. Continuous Earth observations by crew members and new Earth Science payload opportunities on the International Space Station (ISS) will enhance the existing image database and our knowledge of processes and changes on the Earth's surface.

This activity has resulted in a large data base of Earth images, including photographs that document significant changes in morphology and landuse in the world's great deltas. The deltaic system of the Yellow River is one of the world's most dynamic; it changed extensively over the ten year period from 1989 to 1999. Using photographs taken by astronauts, we have analyzed the cycle of accretion and erosion at the tip of the Yellow River delta. Our calculations indicate that the exposed delta grew 390 km2 between 1989 and 1995. Between 1995 and 1997, the delta eroded 319 km2, due to drought and the creation of a new channel. We have extrapolated our analyses to estimate fluxes in sediment volumes. In addition to their use for quantitative change detection, astronaut photographs also offer less typical Earth views which can be advantageous for the study of deltas. These include sunglint views that highlight the land-water boundaries and allow quick assessment of coastline and wetland change. Views at oblique angles provide regional context for the geological and anthropogenic processes influencing delta change. Color infrared views highlight vegetation and reveal key information about patterns of urban, agricultural and wetland changes. Using combinations of these data, changes due to variable water supply, sedimentation, subsidence, dredging, channelization, and shifts in landuse can be mapped. In the near future, the International Space Station (ISS), with potential for continuous imaging through high quality windows or attached sensors, will provide additional opportunities for documenting the changes occurring in these dynamic coastal regions.

An understanding of recharge to these nonrenewable resources is critical to make sound decisions related to water supply and cleanup. Groundwater studies at Edwards AFB indicate that Pleistocene age groundwater occurs between the contaminated groundwater area and the downgradient portions of the aquifer that are used for water supply. This groundwater system is being studied to establish the priority of remediation efforts at Edwards AFB. The slow moving Pleistocene groundwater at Edwards AFB is a critical consideration for cleanup decisions. On one hand, the nonrenewable aspect of the Pleistocene age groundwater resource can be used as rationale to prevent its degradation or to justify remediation at Edwards AFB. On the other hand, the slow rate of groundwater movement may warrant alternative remediation techniques like natural attenuation, institutional control, and long-term monitoring. Modern infiltration to the groundwater beneath the western edge of Rogers Dry Lake is limited to localized recharge areas. At one such area, the NASA Dryden Flight Research Center (Dryden), tritiated groundwater has been impacted by chlorinated solvents and petroleum hydrocarbons associated with previous flight research activities. Groundwater flows east from the Dryden area toward the middle of Rogers Dry Lake where groundwater does not contain detectable tritium concentrations and carbon-14 dating indicates mean residence times as high as 22,000 years. From the middle of Rogers Dry Lake, groundwater flows north toward the town of North Edwards where groundwater is used as a water supply.

To evaluate the continuous habitability of these planets, one needs to consider only the most dangerous events and the relative frequency of planetary sterilization and interplanetary exchange of life. The global killing mechanism of large impacts was ocean-boiling heat on the Earth and global molten ejecta blankets on Mars. Both processes are constrained by the conversation of energy. A 300-km diameter asteroid would leave only thermophile survivors on the Earth and a 500-km diameter projectile would completely evaporate the ocean. The habitable subsurface extended to much greater depths on Mars than on the Earth and provided a safer refugium than anywhere on the Earth. Only a few globally dangerous impacts occurred on each planet separated by tens of million years. The origin of life there must be distinguished from bottlenecks which left a few survivors. Small impacts which ejected rocks potentially exchanging life between planets were much frequent than dangerous ones. The tree of extant terrestrial life shows features expected of impact survivors. The Bacteria and Archaea roots are thermophile. The last common ancestor was a complex highly evolved organism. There are subtle hints of interplanet exchange and that the Eucarya last common ancestor was a late colonist to the Earth.

Earth, Mars and other silicate planets shared trends (e.g., bombardments, crustal development, declining heatflow and increasing solar luminosity) whose similarities help us chart the distribution of habitability across space and time. We recognize that habitable environments must provide liquid water and biochemically-useful energy, but we do not fully comprehend the diversity of chemicals and morphologies that these environments create that are nonbiological yet mimic biomarkers. Ancient Mars illustrates this. Although the early Sun was less luminous, the martian surface was wetter and warmer because greater geological activity sustained stronger atmospheric greenhouse warming. To achieve this warming, H (sub 2) O and CO (sub 2) were perhaps supplemented by CH (sub 4) and other reduced greenhouse gases. Thus, evidence that the martian surface was more clement might also constitute evidence that reduced gases and other organics and reduced minerals (including iron and sulfur species) were formed. If so, were they all synthesized abiotically? If some were biotic, how will we recognize this? Some extinct springs are associated with ancient volcanism, indicating hydrothermal activity. Did reduced species form within hydrothermal systems? Were those systems habitable, inhabited? Perhaps we can propose universal properties of life that assist our search for martian biomarkers. All Earth-based life is cellular and requires liquid water. The covalently-bonded components of biological systems are dominated by C, H, N, O, P and S. The set of biomolecules and biochemical reactions is a very small subset of all possible organic chemistry. Thus a high degree of chemical specificity can be a bioindicator. Life employs enzymes in redox reactions that harvest energy gradients. We should thus look for redox catalysis within chemical gradients (situated at environmental interfaces, for example). To persist, life requires ecosystems. Thus we should search for emergent ecosystem properties such as biofilms and mineralogical features that require biologically-created microenvironments. Only by testing the specificity and applicability of such properties of life can we effectively interpret returned martian samples.

There are numerous signs of past liquid water on Mars in the form of dry river valleys, paleolakes, and their associated flow and sediment patterns. While some of these features are recent (Amazonian), there is no evidence that any are currently flowing. Liquid water is unstable on the Martian surface due to the low temperature and atmosphere pressure, so any water on the surface would be frozen until it is sublimated. Therefore, existing life on Mars is very unlikely, unless it either exists as cryptoendoliths (microbes living inside of rocks) on the surface or associated with hydrothermal systems and subsurface aquifers. Life on the surface would be difficult due to the dryness, oxidizing soil and atmosphere, and the ultraviolet radiation. Subsurface life on Mars may exist several kilometers below the surface. Spatial data layers derived from remote sensing instruments could be analyzed in a geographic information system (GIS) to locate biologically interesting areas and to select potential landing sites on Mars. The search for extant life on Mars is a two-step approach: (1) study Mars-analogs on Earth, then (2) look for signatures of life on Mars. The study of Earth analogs of potential Martian-life regimens is needed to determine the hydrothermal-life signatures using remotely sensed data. Some potential sources of remotely sensed data would be gamma-ray/neutron and near-, mid-, and thermal-IR spectroscopy. These signatures may include spatial data layers or maps of atmospheric pressure (carbon dioxide concentration on Mars), water vapor concentration, biomarker-gas concentrations, mineralogy, surface temperature, canyon depths, and paleolakes. Once these signatures are determined for features on the Earth, recommendations for orbiter, lander, and rover instruments can be made. Some example GIS analyses of existing data layers, such as surface temperature, topography, atmospheric pressure, and water vapor distribution, will be conducted.

AN - 52258672; 2001-019217 AB - Much current thinking in astrobiology is driven by the idea that because life arose rapidly on Earth it likely will take root on any planet where the proper environmental conditions exist. Finding evidence for life on Mars would do much to support this hypothesis. Failure to discover biological signatures in Mars rocks, however, could result from inadequacies in our search strategy, an inability to determine what constitutes appropriate evidence for biogenicity, or, of course, a flaw in our hypothesis. To search effectively for signs of life in martian samples, we must identify locations that have been (or are) conducive to biological activity, land a spacecraft there with high precision, identify rocks most likely to retain some physical or chemical remnant of life, collect samples, and return them to Earth in nearly pristine condition. Once samples are in hand, proper interpretation will require that we understand their geological and geochemical context and have in place an improved understanding of the uniqueness and generality of biological indicators. Each of these tasks is daunting. Regardless of the outcome of the search, the results will take us an important step closer to understanding life's distribution beyond the Earth.

The polymer consists of polysaccharide chains and is exuded by bacteria to form a protective layer of slime in which they can multiply and metabolise. Bacteria can control the microenvironment of the biofilm, causing the precipitation and dissolution of minerals, heterogeneity of structure, and gas bubble production. Furthermore, the sticky polymer traps allochthonous particles, thus building up a complex microbial mat. Biofilms are readily fossilised; the active group molecules of the polysaccharide chelate with mineral ions in solution, thus preserving the biofilms by permineralisation. Given the large volume of organic carbon in the original biofilm, much of it remains trapped in the mineral matrix. With diagenesis and metamorphism, the organic carbon degrades, becoming kerogen. However, where alteration is not extreme, the structure of the biofilm may be faithfully recorded and the degradation products of certain molecules peculiar to bacterial polymer may still be detected, as in 3.5 billion-year old carbonaceous cherts from the Barberton greenstone belt in South Africa. Both tabular and vertical types of stromatolites are characterised by laminations produced by microbial mats. The structure and texture of these laminations can be successfully used to document a microbial origin, even when there are no associated microfossils. The techniques used in the study of fossil biofilms include a combination of light microscope, SEM and EDS, and TOF-SIMS for bacterial polymer, trace elements and biomolecule identification. Biofilms are, thus, ideal biomarkers in terrestrial and extraterrestrial materials for the following reasons: (1) they are ubiquitous in biogenic sediments, (2) they are robust, (3) the structures that they produce range from the macroscopic to the microscopic, (4) they are characterised by a unique texture and structure, and (5) the degradation products of certain molecules appear to be resistant through time.

AN - 52248387; 2001-023968 AB - Fine-grained magnetite crystals, in the Fe-rich rims of carbonate globules of martian meteorite ALH84001, have been proposed as fossil remains of primitive Martian organisms. We report observations on the size and shape distributions and chemical compositions of magnetites from ALH84001 and compare them to biogenic and inorganic magnetite crystals of terrestrial origin. Magnetite is found in a wide variety of terrestrial rock types and in meteorites, but none has been reported with the specific and unique characteristics of magnetites produced by various kinds of magnetotactic bacteria. We suggest that magnetite in ALH84001 carbonate globules might be explained by low temperature, inorganic and biogenic processes. A significant fraction of magnetite has a pure chemical composition, unique morphology, and length-to-width ratio that are indistinguishable from a variety of terrestrial biogenic magnetite but distinct from all known inorganic forms of magnetite. Unless an inorganic analog for these crystals is found, the presence of elongated prismatic magnetite crystals associated with the carbonate globules in Martian meteorite ALH84001 must be considered as strong evidence for primitive life on early Mars. Although high temperature mechanisms have been suggested by others for the formation of whisker-shaped magnetite in ALH84001, we suggest that all ALH84001 magnetite likely formed in the presence of low temperature fluids.

Returned Mars samples will become available for study in the year 2008 and it is essential that we establish criteria for the identity of fossil or extant life in these rocks. However, at the present time there are no unequivocal inorganic diagnostic features which can be used as proof of life, and the use of morphology alone has proved flawed. Especially relevant in this regard are the recent conclusions reached by Kirkland et al. (1999, Geology v. 27) and the National Research Council (Workshop on the Size Limits of Very small Organisms, Oct. 1998). Without the development of objective, definitive criteria for the presence or absence of life, neither the lay public nor the science community will consider such claims credible. We have begun to characterize submicroscropic "bacteria-like" features on fracture surfaces from extraterrestrial material and terrestrial rock samples with known biotic and abiotic affinities. The samples include chondrite meteorites and the martian meteorites ALH84001, Nakhla and EET79001, and carbonate globules within the Spitzbergen ultramafic xenoliths that are analogous to those found in ALH84001 (Blake et al., 1999, LPSC XXX, Abstract 1683). We have prepared SEM grain mounts of material containing these features, and have begun investigating their composition and structure. We have found morphological features in these samples that are similar in form to those purported to be of biological origin in the martian meteorites, but the samples we have examined have no apparent biological affinity. In addition, we have begun characterizing submicroscopic inorganic magnetite populations from a variety of sources and comparing them to magnetite populations present in the ALH84001 meteorite and within natural magnetotactic bacteria.

Cyanobacterial mats comprising the surface of these lithified structures suggest biogeochemical mediated stromatolite formation. In situ and shipboard measurements were carried out in Highborne Cay, at the north end of the Exuma Cays. Microscale investigations included geological observations such as thin sectioning, SEM, and measurements of the distribution of lithified and unlithified horizons with a micro-penetrometer. Microbial analysis included rate measurements with microelectrodes and radiolabeled substrates and population determination with epifluorescence microscopy and serial dilutions in specific microbial media. Also determined were microbial community composition, inorganic nutrients and sulfur species in the porewater, pH depth profiles, and organic nutrient utilization by various groups of microorganisms. Trapping and binding by filamentous cyanobacteria is important for Exuma stromatolites, resulting in the accretion of carbonate sand. Active precipitation and dissolution mediated by microorganisms yields lithification of the accreted carbonate sand. Endolithic microboring by cyanobacteria results in micritization. Combining the biogeochemical microscale observations described above led to a conceptual model in which spatial and temporal separation of other microbial processes also contribute to formation of lithified horizons: Oxygenic photosynthesis precipitates calcium carbonate while aerobic respiration by heterotrophic bacteria dissolves this. Furthermore, sulfate reducing bacteria and sulfide-oxidizing bacteria play an important role in formation of micritized layers. When oxygen concentrations are low, sulfate reduction rates are high. Under these conditions, the sulfide produced during sulfate reduction is only partially oxidized. Reduction of sulfate and oxidation of sulfide combined result in a high precipitation rate. When oxygen concentrations are sufficiently high again (and as a consequence, sulfate reduction rates low), complete oxidation of the sulfur intermediates lead to calcium carbonate dissolution. Penetrometer and microelectrode measurements and silver foil incubations were instrumental in obtaining measurements on a micrometer scale. The current challenge is to further decrease the spatial and temporal scales of biogeochemical observations, preferably in a non-destructive way.

AN - 52244155; 2001-027712 AB - The now-famous Raup & Sepkoski (1984) study found a statistically significant 26 m.y. to 30 m.y. periodicity in extinctions over the last 250 Myr. These results have been questioned, but several lines of evidence suggest that the extinction periodicity is robust, although the exact period is still somewhat uncertain. We tested the period and phase of the cycle in light of models paced by the oscillation of the Solar System through the galactic disk. For extinctions over the last 250 Myr, if the phase is allowed to vary freely, only one high spectral peak at 27 m.y. is apparent. With phase fixed at the present time of plane crossing, however, the highest peak shifts to 28 m.y., and peaks at 32 and 35 m.y. become more prominent. Fourier analyses of extinctions over the past 545 Myr show a dominant peak between 26 and 27 m.y., but also subsidiary peaks at approximately 30 and 36 m.y. The Raup & Sepkoski paper prompted immediate statistical tests of the impact record by Rampino & Stothers and by Alvarez & Muller, who found periods ranging from 28 to 31 m.y., but these results have also been contested. Recent time-series analyses using a new list of 34 large, well-dated craters, detected a narrow peak at 30+ or -0.5 m.y. and a broader peak at 35+ or -2 m.y. When only the largest craters were utilized, and phase was set at the present, the approximately 36 m.y. peak became the highest in the period spectrum. Statistical tests suggest that the observed differences in the formal periodicities in cratering and extinctions are to be expected, taking into consideration problems in dating, the short time series, and the likelihood that the records are mixtures of periodic and random events.

Subsequent scanning and transmission electron microscope (SEM and TEM) studies revealed the presence of several types of bacteria and biofilm, some of which were mineralized. Some of these biological features are very similar to possible biogenic features found in two meteorites from Mars, ALH84001 (found in Antarctica) and Nakhla (observed to fall in Egypt). Both ALH84001 and Nakhla contain traces of low-temperature aqueous alteration of silicates, oxides, and sulfides. The goals of this study are to use high-resolution field-emission SEM (FE-SEM) to examine the CRB samples for evidence of alteration features similar to those in the martian meteorites, to determine the extent of alteration during the CRB microcosm experiments, and to determine whether effects of biological activity can be distinguished from inorganic effects.

Filamentous fossil bacteria have been described in thin sections of the same samples using light microscopy. Chips of the samples were broken off with a rock hammer and chips with no evidence of fracturing or weathering immediately gold-coated for 30 seconds. The most abundant filamentous fossils detected by light microscopy have cross-sectional diameters of <0.5 to 1 microns and, though rarely preserved, are clearly indigenous to original microbial mat-like laminations. The same structures were detected by SEM and appear to be kerogen-lined tubes completely encased by silica. Abundant wider, septate filaments were also observed on two fracture surfaces of one of the samples. Several protuberances at regularly spaced intervals along the filaments are similar to clamp connections in fungi of the Phylum Basidiomycota. Also present on the fracture surfaces are possible fungal spores with spiny exterior walls. The fungal structures appear in some cases to be encased within the silica matrix, suggesting that they have been fossilized. It appears that two generations of filamentous structures are present in one sample: 1) Archean fossil bacteria and 2) younger fungi. Fungi are not present in the fossil record until the late Proterozoic, and clamped hyphae are first known in the Carboniferous, associated with woody plants. The results of this on-going study reinforce the need for a combined use of light microscopy, valuable in determining the spatial relationships of fossil-like structures to sedimentary and petrologic features, and SEM, which allows examination of much finer structural features as well as chemical analysis, in the study of fossil bacteria in both terrestrial and extra-terrestrial samples. TOF-SIMS analyses may aid understanding of the time-dependent degradation of biomolecules in the two generations of microfossils.

These stromatolites are composed primarily of fine grained carbonate sand that is trapped and bound by filamentous cyanobacteria (Schizothrix sp.). Periodic introduction of coccoid endolithic cyanobacteria, Solentia sp., results in formation of lithified horizons, 200 to 1000 mu m thick. We used SEM and petrographic analyses to examine both naturally occurring lithified layers dominated by endoliths and fused oolitic crusts generated in the laboratory by activity of endolithic cyanobacteria (Solentia sp.). Fused grain crusts consist of micritized grains that are welded together at point contacts. Micritization results from extensive microboring and rapid (days to weeks) carbonate precipitation within the bore holes. This precipitation appears to occur concurrently with further endolithic activity within the grain. Infilling of bore holes that cross from one grain to another at point contacts results in grain welding. Thus, while microboring destroys original grain textures, at the same time the endolith activity plays a constructional role in stromatolite growth by forming lithified layers of welded grains. These framework structures help to stabilize and preserve the stromatolite deposits.

High resolution scanning electron microscopy (FEG-SEM) and energy-dispersive X-ray spectrometry (FEG-SEM/EDS) yield new information with which these guidelines can be expanded, including geochemistry. Therefore, we will outline below a set of FEG-SEM/EDS criteria for identifying syngenetic microfossils in ancient rocks, especially in view of the possibility of similar features in martian rocks. The first criterion is that the samples should be freshly fractured chips from the interior of a specimen. The FEG-SEM can be used to search for evidence of small-scale fracturing and weathering that is too small to be identified optically. If such evidence is present, any nearby biogenic features should be suspected to be the result of biological activity that occurred at the same time as the weathering (i.e., the microfossils are not syngenetic with the rock). Second, as is also true for traditional optical criteria, replicate sampling and reproducibility are imperative because contaminant microbes are more likely to be restricted to small (nm-mm sized) areas. Third, in order to verify syngenicity, microfossils must be demonstrably part of the rock; i.e., some of them must be partially or completely embedded in the groundmass, and some may be fractured along the same planes as the groundmass. Backscatter analysis enhances visibility of partially embedded microfossils. Fourth, EDS compositions and elemental maps can help identify latter-day immigrants (LDIs) because if a microfossil contains metallic ions that are not present in the matrix of the rock, fossilization may not have been contemporaneous with lithification.In conclusion, we strongly recommend the use of enhanced technological tools such as FEG-SEM/EDS that incorporate backscatter methods to identify microscopically restricted weathered areas, including anomalous chemical signatures, that include probable biogenic LDI's.

This reef consists of an algal ridge that grades shoreward to a back reef lagoon with a diversity of microbial buildups. Intertidal stromatolites and thrombolites form tabular mounds several meters in diameter in the nearshore zone and shallow subtidal stromatolites form ridges and columnar heads up to half a meter high in the sandy lagoon. A tufa-like rock forms ridges at the bases of some of the thrombolites. The algal ridge is composed mainly of the branching crustose coralline alga, Neogoniolithon strictum, which, until recently, was not known to form algal ridges. The coralline algae are commonly coated with micritic crusts of possible microbial origin. This unusual reef is an ideal system for geomicrobiological studies. The stromatolites at Highborne Cay exhibit superb lamination. Consequently this site was chosen as the primary study site for a multidisciplinary study of processes forming modern marine stromatolites. This project, known as the Research Initiative on Bahamian Stromatolites (RIBS), has conducted integrated studies of stromatolite microstructure, microbial ecology and biogeochemistry. The results indicate that periodic episodes of lithification occur within cyanobacterial mats on the surfaces of the stromatolites. This leads to formation of indurated micritic laminae with a characteristic microstructure: micritic crusts, 20-40 microns thick, overlie layers of micritized sand grains about 1 mm thick. Precipitation of micrite within these lithified layers is associated with organic films, heterotrophic bacterial decomposition, and endolithic microboring.

These data are then used to gauge whether this process is a viable mechanism for producing C-13-enriched carbonates like those found in the Martian meteorite ALH 84001, which we have shown previously to contain the most C-13-enriched carbonate yet reported for an SNC (Mars) meteorite ( approximately +41 per mil [VPDB]). Cryogenic calcite is produced when carbon dioxide degasses from bicarbonate-rich water during freezing. In order to test this phenomenon under controlled laboratory conditions, a calcium bicarbonate solution, made by prolonged bubbling of pure carbon dioxide gas through a saturated solution of calcium hydroxide, was subjected to two different laboratory freezing experiments. In one experiment the calcium bicarbonate solution was sampled several times during the freezing process and analyzed for C-13, while monitoring pH. C-13 composition of the solution ranged from -25.8 per mil (pH = 6.0) at t = 0 min. to -22.6 per mil (pH = 6.6) at t = 270 min. Precipitated calcite (sampled by melting and filtering the ice) had a C-13 composition of -9.8 per mil. A second experiment involved freezing a portion of the original solution in a shallow bowl and analyzing small ice cores sequentially from the outside toward the center of the bowl. Here, C-13 composition ranged from -15.7 per mil at the edge to -8.0 per mil at the center, while calcite had a C-13 composition of -12.3 per mil. This solution was further subjected to freezing producing a 2nd generation calcite with a C-13 composition of -8.8 per mil, whilst a 3rd generation calcite had a C-13 composition of -6.3 per mil. Clearly, the isotopic trends in both experiments indicate C-13 enrichment in both DIC and solid calcite, thus offering cryogenic freezing as a possible explanation for the formation of C-13-enriched carbonates on Mars.

This succession was deposited in a tide- and wave-influenced shallow marine equatorial environment. The age of the Chuar Group is constrained by ca 1.1 Ga Rb-Sr dates on the underlying Cardenas Basalt and by an ash-fall tuff from the uppermost Chuar Group (upper Walcott Member), which yields a concordia upper intercept date of ca. 742 Ma, based on seven single zircons. Black and gray shale delta (super 13) C(org) values ranged from -30 to -14, and dolomite delta (super 13) C(carb) values ranged from -6 to +3, throughout the Chuar succession. Marker beds show reproducible (0.49 and an average delta (super 18) O(carb) >-4, indicate that these delta (super 13) C values from the entire succession could be used to reconstruct a primary delta (super 13) C(carb)-isotope curve. Following previous convention for Neoproterozoic delta (super 13) C stratigraphy, we combine delta (super 13) C(carb) values with delta (super 13) C(org) values shifted by +28.5 to reconstruct the delta (super 13) C(carb) curve. First, the reconstructed curve indicates that virtually all delta (super 13) C(carb) values are >0 for the Chuar. The delta (super 13) C(carb) values decrease uniformly in the uppermost section (Awatubi through Walcott Members) from +13 to +1. This isotope trend, the new 742 Ma age (above), and the Neoproterozoic delta13C global curve, indicate that the Awatubi-to-Walcott succession represents deposition during transition into the Sturtian glaciation. The lithologic change from the Walcott Member to the overlying Sixtymile Formation also indicates environmental change. Isotopic patterns in the lower Chuar succession might offer additional insights about incipient stages of global glaciation.

The individual forcings included altered paleogeography, a 6 percent solar luminosity decrease, reduction of CO (sub 2) to 140 ppm and 40 ppm, and ocean heat transport changes to 150 percent and 50 percent of the modern value. None of these forcings is individually capable of producing year-round snow accumulations on low-latitude continents although the simulations that had either decreased solar flux or 40 ppm CO (sub 2) resulted in snow and ice accumulations in the Varanger mid-latitudes. Combinations of two or more climate forcings are able to further cool the planet and were capable, in extreme scenarios, of extending the annual average freeze line, as well as snow and ice cover, onto tropical continents. No simulation, including an increased obliquity experiment, suggested that it is possible to generate low-latitude glaciation without also creating glacial conditions at higher latitudes. Critical climate feedbacks supported the cooler climates and include an albedo feedback; snow and ice cover as much as 67.5 percent of the planet compared with less than 12 percent in modern climate simulations, and decreased atmospheric water vapor, which drops to 10 percent of its modern level in the most extreme Varanger simulation. Though these particular simulations do not affirm the possibility of a "snowball" Earth climate scenario, they do suggest that somewhat more severe forcings could produce a condition in which the planet became entirely snow- and ice-covered. Under those conditions ice sheet growth would halt, however, since the atmosphere's ultimate moisture source, the ocean, would be cut off.

Accordingly, we have determined carbon isotope discrimination associated with both heterotrophic (organic carbon-utilizing) and autotrophic (CO (sub 2) -utilizing) growth of pure cultures of sulfate-reducing bacteria (SRB). The isotopic composition of cellular constituents and excretion products can reflect biochemical interactions at both intracellular and ecological levels. Therefore, isotopic patterns must be interpreted in the context of kinetic isotope effects that are modulated by networks of enzymatic transformations that compete for key substrates such as acetate. Sealed vessels containing the SRB cultures were harvested at different time intervals, and delta (super 13) C values were determined for gaseous CO (sub 2) , organic substrates, and products such as total cellular carbon. During experiments involving heterotrophic growth, the consumption of carbon substrates was followed to completion. Desulfobacterium autotrophicum, which uses the acetyl-coenzyme A pathway for both carbon fixation and acetate catabolism, expressed different isotope discrimination depending upon the carbon source. Grown lithoautotrophically (using H (sub 2) and CO (sub 2) ) with a large excess of available CO (sub 2) , the biomass was depleted by almost 12 relative to the CO (sub 2) substrate. Grown heterotrophically on acetate, SRB biomass was only 0 to 2 depleted relative to acetate or the final CO (sub 2) pool, whereas the CO (sub 2) released from acetate catabolism was depleted by 7, relative to the acetate substrate. In contrast, Desulfovibrio desulfuricans grown heterotrophically produced biomass and CO (sub 2) that were about 3 lighter than the lactate substrate, and these values did not change significantly as a function of the fraction of lactate consumed. Several preliminary conclusions can be made. Isotopic discrimination associated with autotrophic CO (sub 2) assimilation is significantly larger than with growth using lactate or acetate. Competition for acetate between assimilatory and dissimilatory pathways might affect the relative delta (super 13) C values of biomass and excreted carbon. Thus, by controlling the availability of carbon substrates (e.g., lactate, acetate and CO (sub 2) ) and reducing power (e.g., H (sub 2) ), ecological and other environmental factors can substantially affect carbon isotopic discrimination by SRB.

Although the impacts of landuse to the atmosphere have been included in global models, the impacts to soils are not as well documented for a global or historic perspective. By comparing some pre-historic and modern agricultural sites to respective control sites, we have found that the fate of C and nutrients in soils varies greatly as a consequence of landuse practices. Studies of prehistoric and contemporary Native American agriculture indicate deliberate use of sedimentation as a tool for maintaining soil fertility. Cases of both organic carbon loss and gain relative to control sites have been documented in ancient American agricultural soils. By contrast, historic erosion rates in conventionally cultivated agricultural soils are commonly an order of magnitude faster than in soils prior to cultivation. The fate of eroded C and N, as well as impact on current exchange of C between soils and the atmosphere, is in turn dependent on the fate of sediment and its exposure to decomposition processes. Using a global model of land-use disturbance, we find that the area of agricultural disturbance increased dramatically in the past century and that most of the disturbance was in temperate latitudes as a result of the expansion of modern agriculture. About 20% of topsoil C at these sites was decomposed and released to the atmosphere. Simple models of erosional processes indicate that erosion has depleted topsoil C by an additional 20%. A more complete treatment, including both erosion and dynamic replacement of C by fertilized agriculture, leads to a conclusion that as much as 100% of topsoil C may have been eroded and replaced within a century of intensive farming. The implications for soil fertility are unclear because of the availability and wide use of fertilizers.

Data collected in Howland, Maine during the Forest Ecosystem Dynamics (FED) experiment in 1990 have been used to validate a discrete scatter model. The model is then used in a series of parameter studies to extrapolate the results to canopies with a wide range of biomass and surface conditions. The objective of this study is to gain insight into the range of biomass over which soil moisture can be measured by the two sensors. Tree and surface parameters are varied to generate different biomass and ground conditions. Both radar and radiometer exhibit sensitivity to soil moisture under a wide range of conditions. How these sensitivities diminish with increasing biomass and surface roughness is an important factor in the response of both sensors.

Since the initial report of the evidence supporting this hypothesis, many laboratories around the world have studied the Antarctic meteorite. This paper presents a summary of new data and refinements in the original interpretations. The polycyclic aromatic hydrocarbons (PAHs) found in the meteorite have been suggested by some researchers to be the product of contamination of the meteorite while residing in the Allan Hills ice. The authors assert that the ice and meltwater in the region where the meteorite was found contain no detectable level of polycyclic aromatic hydrocarbons and, while much of the organic material found in ALH84001 is from terrestrial contamination, the PAHs are still extraterrestrial. Carbonate, sulfide and iron oxide minerals found within the meteorite are interpreted by the authors as biogenic in origin. Possible abiotic and terrestrial explanations are still being debated. The final indicator, bacteria-shaped objects, continue to be examined and compared to non-biologic forms. Size constraints on bacterial forms and the impact of drying out is reviewed.

Two groups of mineralized springs occur near the McGill University Axel Heiberg Research Station located at 79 degrees 26'N, 90 degrees 46'W. The first is at Gypsum Hill, 3 km from the terminus of the White and Thompson glaciers, and the second site is at Colour Peak, approximately 10 km downvalley near the head of Expedition Fiord. Each spring group consists of 20-40 vents spread over several hundred square metres. The highly mineralized nature of the discharge causes a freezing-point depression of 7-10 degrees C and produces a range of precipitates and travertine deposits. Year-round water temperature and discharge rate measurements have been obtained, demonstrating perennial activity at these sites. Results indicate that temperatures range from -4.0 to 6.6 degrees C among the individual sources; however, water temperatures at the various outlets remain constant throughout the year despite a mean annual air temperature of -15 degrees C. Although discharge from any one outlet is low (<0.5 to 2.0 L/s), the total discharge is substantial, each year producing several seasonal frost mounds and an icing 180 000-300 000 m (super 2) at the Gypsum Hill site.

These deposits have many proposed hypotheses of origin (ignimbrites, massive aeolian deposits, paleopolar deposits and carbonate platforms). Photogeologic mapping has revealed several subdivisions of the members identified from global mapping, many of which appear to occur as discreet layers. Measurements by the Mars Orbiter Laser Altimeter (MOLA) have provided the first precise topographic control for these materials, revealing significant relief within the MFF, few near-horizontal top surfaces, and regional-scale "fluting" perpendicular to the dichotomy boundary that suggests material removal. Regional topography and MOLA profile data allow us to test mapped units for topographic consistency. In the detailed mapping area (2.5 degrees S to 7.5 degrees N, 140 degrees to 145 degrees W), upper member subdivisions of MFF are highest, and are reasonably consistent with a horizontally layered deposit. The middle member of MFF is more complex, showing considerable topographic variation between exposures. Localized exposures of basement lava plains, stratigraphically below MFF, confirm that MFF occurs on materials of the transition zone between the southern highlands and the northern lowlands, all on a regional slope down to the north throughout the study area. Precise topographic boundaries can soon be established for the various materials exposed in the study area as additional MOLA data become available; these data will provide quantified constraints that must be accommodated by any successful hypothesis of origin for MFF.

For example, crater degradation does not appear entirely consistent (e.g., most crater rims are circular rather than ellipsoid, several continuous ejecta blankets are visible) with regions imaged previously. However, degradation of crater rims and high-standing knobs is in general similar to what has been observed and described from previous imaging. Mass wasting from crater walls, knobs, and scarps is commonly observed in both GEM and nominal mission images. Intercrater deposits (typically approximately 1-10 km (super 3) ) have flow- to slump-like morphologies. Dark material occurring in patches at the base of bright knobs or scarps may be sublimated lag deposits. The degradation of craters appears to follow a morphological sequence where continuous bright rims are weathered and dissected (perhaps controlled tectonically), resulting in numerous bright knobs interspersed with low-lying dark material. Erosion and transport of crater rim and/or wall material may be a significant contributor to the burial/removal of small (<10 km diameter) craters on Callisto. These similarities and differences in degradation are interpreted to be the result of processes that occur globally, but which may by influenced locally. Factors responsible for local effects (e.g., longitude, latitude, albedo) are being investigated. Impact cratering and landform degradation are the dominant processes operating on Callisto as seen in Galileo images. Features in Voyager data, however, suggested that some regions of Callisto may have been cryovolcanically resurfaced. One of these regions was imaged to determine the nature of resurfacing. In the target area dark material, similar to that seen in other areas on Callisto, occurs in a large patch devoid of brighter hummocks or high-standing knobs. In low-resolution Voyager images this gives the incorrect impression of extruded dark material (cryovolcanism). Tectonic features (e.g., fractures, graben), seen as dark lanes in Voyager data, appear (usually) to be the remnants of degraded multiring structures.

The Mars Color Imager (MARCI) consists of two cameras which acquire data from the ultraviolet to 1000 nm. The Wide Angle camera will provide global maps of atmospheric phenomena at 7.2 km/pixel. The Medium Angle camera (MA) can image the surface at 40 m/pixel in seven spectral bands between 425 and 1000 nm. Though primarily an atmospheric experiment, MARCI will provide information on regional color units and compositional constraints on surface materials that are complementary to orbited infrared instruments. A description of the instrument and observing plans will be presented along with initial images from the first month of operations.

Some of these biomarkers have been well characterized. They have been found in both ancient and recent terrestrial rocks; their presence is evidence for life, often in extreme environments. It is unclear if other potential biomarkers point only to biogenic activity thereby excluding other possible sources such as low or high temperature inorganic processes. If the feature properties are similar to the properties of known biomarkers, the biomarker validity is strengthened, and if the properties are more similar to those of features produced by non-biologic processes, the biomarker validity is weakened. If it can be shown that the properties of any of the proposed biomarkers in the Martian meteorites can only be produced by biologic activity, that biomarker is clear proof of past life on Mars (assuming the biomarker is also shown to be indigenous). We strongly suggest that elongated hexagonal prismatic single-domain magnetites in the ALH84001 carbonate rims are extremely similar to crystals known to be produced by magnetotactic bacteria on Earth. If we can also show that it is not possible to produce the properties of these magnetites by non-biologic processes, and that they are indigenous to Mars, that alone is proof of past life on Mars. Another example is the fossil-like forms in Nakhla. If it can be shown that their properties closely match fossilized earth bacteria, that non-biologic processes cannot form them, and that they are indigenous to the pre-terrestrial history of this Martian meteorite, then they are clear proof of past life on Mars. The most difficult step may be showing that inorganic processes cannot form specific potential biomarkers.

The importance of hydrothermal systems as targets in exploring for an early biosphere on Mars is well established and provides an important basis for the analysis of Martian samples. The surviving molecular structure and isotopic signature of diagnostic lipid biomarkers found as chemical fossils can provide a link between modern microbial ecosystems and their ancient counterparts. We are interested in the deposition of biomarkers in moderately thermal, silicifying microbial mats, particularly in preservation of biomarker components known to be more resistant to degradation such as the 2-methylbacteriohopanepolyols (2-MeBHP) of cyanobacteria. These compounds are ubiquitous on Earth, are not easily degraded in nature, and have been detected in ancient Earth rocks dating back to 2,500 Ma. In our studies of the early diagenetic effects on biomarkers, we have found a significant correlation between silicification and the preservation of hopanoid compounds. We are studying the tufted Phormidium mats widely prevalent in the terraced pools of the Midway Geyser Basin; a well studied analog system for ancient coniform stromatolites. Within ponded systems, a variety of silicifying regimes are apparent. In the deeper ponds, robust mats develop with moderate silicification apparent throughout the mat framework. 2-MeBHPs, depleted in C-13 by approximately 26 permil, are prevalent throughout but gradually accumulate with depth into a heavily silicified base where cyanobacterial polyunsaturated fatty acids (PFA) no longer persist. By contrast, damming and changes in spring flow often result in silification of the top photic zone forming a heavily encrusted layer. Unlike submerged mats, this top layer showed higher levels of PFA and lower 2-MeBHP abundance which decreased with depth although hopanoid C-13 depletions were about equivalent. Our results suggest that silicification mechanism can have a profound effect on early diagenetic alteration of biomarker composition.

By analogy to Earth, specialized microbes may have existed in the heated, mineralized waters. Precipitates of carbonate and/or silica from these waters may have trapped and preserved evidence of life over long periods of time. Moderate-temperature (60-70 degrees C), neutral carbonate springs at Le Zitelle (Italy), Narrow Gauge (Yellowstone, WY), Hot Springs National Park (AR) and Jemez Springs (NM) support diverse microbial communities. Filamentous microbes are engulfed in precipitating aragonite and rapidly destroyed but sometimes leave distinct mineral fabrics called "streamers". Other microbes coexist with mineral deposits in endolithic communities. Thermal spring microbes produce abundant organic mucus and form extensive biofilms, which can be mineralized and preserved long after the microbes die. Masses of spheres, 50 to 500 nm in diameter, are common in carbonate thermal spring deposits. The spheres may be composed of calcium fluoride (fluorite), calcium phosphate (apatite) or silica (opal). Published experiments show that fluorite can precipitate as submicrometer spheres but only in the presence of trace amounts of organic material. This implies that the fluorite spheres in our samples are biologically mediated precipitates, not living or fossilized organisms. Microbes actively corrode calcite crystal surfaces in characteristic patterns. The physical biomarkers common to carbonate thermal springs which survive for long periods include: streamer fabrics, mineralized biofilms, submicrometer mineral spheres and corroded crystals. The recognition of such biomarkers in thermal spring deposits on Mars would provide powerful evidence of an ancient Martian biota.

Our analysis utilizes simulated monthly estimates of atmospheric pressure and CO (sub 2) polar frost as calculated by the NASA Ames general circulation model (GCM) for a "typical" year. We show that the deposition and sublimation of CO (sub 2) polar frost is expected to be the dominant effect on the gravity field at all low degrees. Variations in the amplitude and phase of time variations of gravity are sensitive to multiple factors, including polar elevation and the eccentricity of the Martian orbit. Phase effects associated with additive and competing influences at the summer and winter poles dictate that odd-numbered harmonic coefficients produce an annual signal in the gravity field while even-numbered coefficients show a semiannual signal. The predicted changes in the planetary flattening and pear-shaped terms of the field are at or above the noise level of expected X band Doppler tracking observations from Mars Global Surveyor and so could conceivably be detected from an orbital spacecraft.

It is less well appreciated that growth and decay of polar ice sheets perturb the symmetry of the global mass distribution enough that the geographic location of the rotation axis will change by at least 15 km and possibly as much as 100 km during a single glacial cycle. This motion of the pole will change the seasonal and latitudinal pattern of temperatures. We present calculations, based on a diurnal average energy balance, which compare the summer and winter temperature anomalies due to a 1 degrees decrease in obliquity with those due to a 1 degrees motion of the rotation pole toward Hudson Bay. Both effects result in peak temperature perturbations of about 1 degrees Celsius. The obliquity change primarily influences the amplitude of the seasonal cycle, while the polar motion primarily changes the annual mean temperatures. The polar motion induced temperature anomaly is such that it will act as a powerful negative feedback on ice sheet growth. We also explore the evolution of the coupled system composed of ice sheet mass and pole position. Oscillatory solutions result from the conflicting constraints of rotational and thermal stability. A positive mass anomaly on an otherwise featureless Earth is in rotational equilibrium only at the poles or the equator. The two polar equilibria are rotationally unstable, and the equatorial equilibrium, though rotationally stable, is thermally unstable. We find that with a plausible choice for the strength of coupling between the thermal and rotational systems, relatively modest external forcing can produce significant response at periods of 10 (super 4) -10 (super 6) years, but it strongly attenuates polar motion at longer periods. We suggest that these coupled oscillations may contribute to the observed dominance of 100 kyr glacial cycles since the mid-Pleistocene and will tend to stabilize geographic patterns that are suitable to glaciations.

Both Budyko's original equation and the new variability equation perform well when tested against results from a 20-yr GCM simulation. In these tests, using knowledge of the climatological mean precipitation and net radiation alone, the authors predict the ratio of annual evaporation to annual precipitation with a standard error of 0.10 in nondesert regions, and they predict the ratio of the standard deviation of annual evaporation to that of annual precipitation there with a standard error of 0.14. In analogy with Budyko's conclusion for the mean hydrological cycle, water and energy availability appear to be the critical factors controlling the interannual variability of surface moisture fluxes. The derived equations suggest, and the GCM results confirm, that the ratio of an evaporation anomaly to the corresponding precipitation anomaly tends to be significantly less than the ratio of mean evaporation to mean precipitation.

The two primary characteristics that make remote sensing a potentially powerful tool are its ability to provide spatial information and to measure directly state variables such as surface temperature and soil moisture. A hypothesis is presented, with remote sensing examples, that many hydrologic processes display a unique signature that is detectable with microwave remote sensing. These signatures are in the form of the spatial and temporal distributions of surface soil moisture. The specific hydrologic processes that may be identified include groundwater recharge and discharge zones, storm runoff contributing areas and assessment of non-point source pollution, regions of potential and less than potential evapotranspiration, and information about the hydrologic properties of soils. An argument is made that such estimates may be more useful and physically more meaningful for use in hydrologic models than laboratory-derived data or statistical estimates. The reasoning behind this argument is that what is being observed is a signature of how the soil hydrology is reacting to atmospheric and drainage forcing that reflects the physical properties of the soils, and more importantly, their location within a field and with respect to topography and drainage patterns.

In addition to exercise training as a countermeasure, +Gz (head-to-foot) acceleration training on 1.8-2.0 m centrifuges can ameliorate the orthostatic and acceleration intolerances induced by BR and immersion deconditioning. Study A was designed to determine the magnitude and linearity of the heart rate (HR) response to human-powered centrifuge (HPC) acceleration with supine exercise vs. passive (no exercise) acceleration. Study B was designed to test the hypothesis that moderate +Gz acceleration during exercise will not affect the respective normal linear relationships between exercise load and maximum oxygen uptake, HR, and pulmonary ventilation. Study C was designed to determine if these physiological responses from the HPC runs (exercise + on-platform acceleration) will be similar to those from the exercise + off-platform acceleration responses. From the results of these studies it is concluded that addition of +2.2 Gz acceleration does not significantly influence levels of oxygen uptake, heart rate, or pulmonary ventilation during submaximal or maximal cycle ergometer leg exercise on a short-arm centrifuge.

This report evaluates the aerobic and anaerobic exercise stimulus provided by self-generated lower body negative pressure. A lower body negative pressure cylinder expands and collapses longitudinally, but not radially. As the legs push footward to expand the cylinder, the air pressure in the cylinder decreases, increasing the force required to continue expanding the cylinder. In addition, valves control air flow into and out of the cylinder, and thus workload. In seven supine subjects, knee bend exercise was performed at 19 cycles/min for 6 min. Footward force was measured with load cells, cylinder pressure with a transducer, heart rate from ECG, and oxygen consumption with turbine volumetry and gas analysis. Maximum footward force at the peak of the exercise cycle averaged 1120 +/- 88 N, and pressure within the cylinder concomitantly decreased 26 +/- 3 mmHg below ambient. Heart rate and oxygen consumption increased 75 +/- 4 bpm and 26.3 +/- 1.4 ml O2/kg min from supine resting values, respectively. It is concluded that, with the inlet valve nearly closed, exercise with this device approximates a resistance-type leg press. With more inflow of air, more rapid aerobic knee bends can be performed. This exercise device/concept provides simultaneous dynamic musculoskeletal and cardiovascular stresses without an external power source.

The estimated changes in tropospheric and stratospheric column ozone over a solar cycle are respectively -2.98 plus or minus 1.31 and +8.63 plus or minus 1.99 Dobson units (DU) or -12.6 plus or minus 5.6 and +3.69 plus or minus 0.86% from solar minimum to solar maximum. These values are statistically significant at the 2 sigma level. In comparison, linear trends in tropical tropospheric ozone are not statistically significant. These observations are qualitatively consistent with a modulation effect on tropospheric ozone photochemistry by UV-induced changes in stratospheric ozone. However, in the low NO sub(x) regime of the marine atmosphere, the observed changes are significantly larger than estimated from a photochemical model. Explanation for the solar signal may include subtle solar-induced changes in transport in the troposphere involving low boundary-layer ozone and ozone precursors.

As other investigators have found before, low 85.5-GHz brightness temperatures (215 plus or minus 20 K) were observed from cumulonimbus clouds along the squall line; however, 85.5-GHz microwave brightness temperatures observed from the nimbostratus clouds north of the low center were significantly higher (255 plus or minus 20 K). In situ measurements from aircraft during the Canadian Atlantic Storm Program II showed that heavy snowfall consisting of large tenuous aggregates existed in the nimbostratus clouds at the time of the SSM/I overpass. Distributions of snow, rain, liquid cloud water, and cloud ice mass were computed from a modified version of the fifth-generation Pennsylvania State University-NCAR Mesoscale Model. That model employed a mixed-phase ice microphysics (MPIM) scheme that only considered one type of frozen hydrometeor. The frozen hydrometeor size distributions, density, and mass flux were modified to match the in situ observations where they were available and to account for the SSM/I observations using radiative transfer theory. Those revised hydrometeor representations were constrained to preserve the vertical hydrometeor mass flux distributions obtained from the MPIM scheme throughout the analysis. Frozen dense accreted particles were required near the squall line to account for the microwave scattering effect. Snow aggregates, with density that decreased with increasing size, were needed to reproduce the high brightness temperatures observed from the nimbostratus clouds.

We measured the vocal responses and movements of radiotagged black rails (Laterallus jamaicensis; 26 M, 17 F) to playback of vocalizations at 2 sites in Florida during the breeding seasons of 1992-95. We used coefficients from logistic regression equations to model probability of a response conditional to the birds' sex, nesting status, distance to playback source, and time of survey. With a probability of 0.811, nonnesting male black rails were most likely to respond to playback, while nesting females were the least likely to respond (probability = 0.189). We used linear regression to determine daily, monthly, and annual variation in response from weekly playback surveys along a fixed route during the breeding seasons of 1993-95. Significant sources of variation in the regression model were month (F sub(3,48) = 3.89, P = 0.014), year (F sub(2,48) = 9.37, P < 0.001), temperature (F sub(1,48) = 5.44, P = 0.024), and month x year (F sub(5,48) = 2.69, P = 0.031). The model was highly significant (P < 0.001) and explained 54% of the variation of mean response per survey period (r super(2) = 0.54). We combined response probability data from radiotagged black rails with playback survey route data to provide a density estimate of 0.25 birds/ha for the St. Johns National Wildlife Refuge. The relation between the number of black rails heard during playback surveys to the actual number present was influenced by a number of variables. We recommend caution when making density estimates from tape playback surveys.

Such relations are useful for rainfall measurements by spaceborne radars at attenuating wavelength such as the 2.2-cm Precipitation Radar (PR) on board the Tropical Rainfall Measuring Mission (TRMM) satellite. In addition to attenuation, these relations are complicated by partial beamfilling, hail, and windshear sorting of particles, among others that affect the corresponding ground-based radar reflectivity-surface rain-rate relationships. TRMM-PR observations were simulated based on radar data from Darwin, Australia. The three-dimensional simulated data were classified by rain type according to several radar properties at high altitudes that are not seriously affected by attenuation. These properties are physical parameters relevant to the variations in the desired relationships. The resulting relationships are robust and permit the classification of near-surface rain and the estimation of its intensity. These findings demonstrate the feasibility of such a classification scheme to spaceborne estimates of rainfall by radar such as that on TRMM. A rain retrieval algorithm, which combines space- and ground-based radar data, is proposed. The basic statistical methodology in the algorithm is an adaptation of the Classified Window Probability Matching Method, developed for ground-based radars. In the proposed method, probabilities of the PR-observed reflectivities, taken from nonattenuated regions, are matched to probabilities of ground-based, radar-estimated rain intensities that have been classified into the same precipitation type.

Toward this end a comparison between two independent techniques, designed to classify precipitation type from 1) a disdrometer and 2) a 915-MHz wind profiler, is presented, based on simultaneous measurements collected at the same site during the Intensive Observing Period of the Tropical Ocean Global Atmosphere Coupled Ocean-Atmosphere Response Experiment. Disdrometer-derived quantities such as differences in drop size distribution parameters, particularly the intercept parameter N sub(0) and rainfall rate, were used to classify rainfall as stratiform or convective. At the same time, profiler-derived quantities, namely, Doppler velocity, equivalent reflectivity, and spectral width, from Doppler spectra were used to classify precipitation type in four categories: shallow convective, deep convective, mixed convective-stratiform, and stratiform. Overall agreement between the two algorithms is found to be reasonable. Given the disdrometer stratiform classification, the mean profile of reflectivity shows a distinct bright band and associated large vertical gradient in Doppler velocity, both indicators of stratiform rain. For the disdrometer convective classification the mean profile of reflectivity lacks a bright band, while the vertical gradient in Doppler velocity below the melting level is opposite to the stratiform case. Given the profiler classifications, in the order shallow-deep-mixed-stratiform, the composite raindrop spectra for a rainfall rate of 5 mm h super(-1) show an increase in D sub(0), the median volume diameter, consistent with the dominant microphysical processes responsible for drop formation. Nevertheless, the intercomparison does reveal some limitations in the classification methodology utilizing the disdrometer or profiler algorithms in isolation. In particular, 1) the disdrometer stratiform classification includes individual cases in which the vertical profiles appear convective, but these usually occur at times when the disdrometer classification is highly variable; 2) the profiler classification scheme also appears to classify precipitation too frequently as stratiform by including cases that have small vertical Doppler velocity gradients at the melting level but no bright band; and 3) the profiler classification scheme includes a category of mixed (stratiform-convective) precipitation that has some features in common with deep convection (e.g., enhanced spectral width above the melting level) but other features in common with stratiform precipitation (e.g., well-developed melting layer signature). Comparison of the profiler-derived vertical structure with disdrometer-determined rain rates reveals that almost all cases of rain rates greater than 10 mm h super(-1) are convective. For rain rates less than 5 mm h super(-1) all four profiler-determined precipitation classes are well represented.

We focus our discussion on the features of the control system that lead to mode confusion and error. We first provide working definitions of the term mode and discuss key constructs that contribute to mode error, such as mode ambiguity and user expectations. Following this, we discuss human interaction with automated control systems in general and cockpit automation in particular. To provide a formal description of human interaction with such control systems, we introduce a modeling language, Statecharts, which is used by system engineers to specify complex control systems. We use the Statecharts language to describe the 3 types of modes that are commonly found in modern control systems: interface, functional, and supervisory modes. Examples from cockpit automation are used to illustrate each type of mode. The article concludes with a brief discussion of the links between the mode constructs and formal representation of human interaction with control systems.

The panels are subjected to combined temperature gradient through-the-thickness combined with pressure loading and edge shortening or edge shear. The analysis is based on a first-order, shear-deformation, Sanders-Budiansky-type shell theory with the effects of large displacements, moderate rotations, transverse shear deformation, and laminated anisotropic material behavior included. A mixed formulation is used with the fundamental unknowns consisting of the generalized displacements and the stress resultants of the panel. The nonlinear displacements, strain energy, principal strains, transverse shear stresses, transverse shear strain energy density, and their hierarchical sensitivity coefficients are evaluated. The hierarchical sensitivity coefficients measure the sensitivity of the nonlinear response to variations in the panel parameters, as well as in the material properties of the individual layers.

Ten river basins, each with an area greater than 10 million km2, were also analysed with the equation. For the small scale sites, the mean absolute error (MAE) was 33 mm, representing 4 per cent of the mean observed evaporation and the empirical equation explained 99 per cent of the variance. Evaporation determined for the river basins gave an MAE of 36 mm, 5 per cent of mean evaporation. An adjustable parameter alpha in the equation had a value of 2.6 for the small sites and 1.8 for the river basins. An understanding of the differences in alpha between the 2 location types was developed from an analysis of the effects of spatial variations in annual precipitation and the water equivalent of annual net radiation on the determination of annual evaporation.

AN - 79632064; 11725795 AB - Neutron fluences were measured from 435 MeV/nucleon Nb ions stopping in a Nb target and 272 MeV/nucleon Nb ions stopping in targets of Nb and Al for neutrons above 20 MeV and at laboratory angles between 3 degrees and 80 degrees. The resultant spectra were integrated over angles to produce neutron energy distributions and over energy to produce neutron angular distributions. The total neutron yields for each system were obtained by integrating over the angular distributions. The angular distributions from all three systems are peaked forward, and the energy distributions from all three systems show an appreciable yield of neutrons with velocities greater than the beam velocity. Comparison of the total neutron yields from the two Nb + Nb systems suggests that the average neutron multiplicity decreases with decreasing projectile energy. Comparison of the total yields from the two 272 MeV/nucleon systems suggests that the total yields show the same dependence on projectile and target mass number as do total inclusive neutron cross sections. The data are compared with Boltzmann-Uehling-Uhlenbeck model calculations. JF - Physical review.

AN - 79625626; 11542474 AB - The HZETRN code has been developed over the past decade to evaluate the local radiation fields within sensitive materials on spacecraft in the space environment. Most of the more important nuclear and atomic processes are now modeled and evaluation within a complex spacecraft geometry with differing material components, including transition effects across boundaries of dissimilar materials, are included. The atomic/nuclear database and transport procedures have received limited validation in laboratory testing with high energy ion beams. The codes have been applied in design of the SAGE-III instrument resulting in material changes to control injurious neutron production, in the study of the Space Shuttle single event upsets, and in validation with space measurements (particle telescopes, tissue equivalent proportional counters, CR-39) on Shuttle and Mir. The present paper reviews the code development and presents recent results in laboratory and space flight validation.

AN - 69179024; 10052675 AB - The average track model describes the response of physical and biological systems using radial dose distribution as the key physical descriptor. We report on an extension of this model to describe the average distribution of electron spectra as a function of radial distance from an ion. We present calculations of these spectra for ions of identical linear energy transfer (LET), but dissimilar charge and velocity to evaluate the differences in electron spectra from these ions. To illustrate the usefulness of the radial electron spectra for describing effects that are not described by electron dose, we consider the evaluation of the indirect events in microdosimetric distributions for ions.

Active regulation of water, energy and carbon dioxide fluxes by the vegetation make it an important factor in regulating the Earth"s hydrological cycle and in the formation of the climate. Consequently, human induced conversion of vegetation cover is an important driver for climate change. A number of recent studies, discussed in this paper, emphasise the importance of the terrestrial biosphere for the climate system. Initially, these studies demonstrate the influence of the land surface on tropical weather and climate, revealing the mechanisms, acting at various scales, that connect increasing temperatures and decreasing rainfall to large-scale deforestation and other forms of land degradation. More recently, the significance of the land surface processes for water cycle and for weather and climate in temperate and boreal zones was demonstrated. In addition the terrestrial biosphere plays a significant role in the carbon dioxide fluxes and in global carbon balance. Recent work suggests that many ecosystems both in the tropics and in temperate zones may act as a substantial sink for carbon dioxide, though the temporal variability of this sink strength is yet unclear. Further, carbon dioxide uptake and evaporation by vegetation are intrinsically coupled, leading to links and feedbacks between land surface and climate that are hardly explored yet. Earth"s vegetation cover and its changes owing to human impact have a profound influence on a lateral redistribution of water and transported constituents, such as nutrients and sediments, and acts therefore as an important moderator of Earth"s biogeochemical cycles. In the BAHC science programme, the importance of studying the influence of climate and human activities on mobilisation and river-borne transport of constituents is explicitly articulated. The terrestrial water and associated material cycles are studied as highly dynamic in space and time, and reflect a complex interplay among climatic forcing, topography, land cover and vegetation dynamics. Despite a large progress in our understanding of how the terrestrial biosphere interacts with Earth"s and climate system and with the terrestrial part of its hydrological cycle, a number of basic issues still remain unresolved. Limited to the scope of BAHC, the paper briefly assesses the present status and identifies the most important outstanding issues, which require further research. Two, arguably most important outstanding issues are identified: a limited understanding of natural variability, especially with respect to seasonal to inter-annual cycles, and of a complex ecosystem behaviour resulting from multiple feedbacks and multiple coupled biogeochemical cycles within the overall climate system. This leads to two major challenges for the future science agenda related to global change research. First, there is a need for a strong multidisciplinary integration of research efforts in both modelling and experiments, the latter extending to inter-annual timescales. Second, the ever increasing complexity in characterisation and modelling of the climate system, which is mainly owing to incorporation of the biosphere"s and human feedbacks, may call for a new approach in global change impact studies. Methodologies need to be developed to identify risks to, and vulnerability of environmental systems, taking into account all important interactions between atmospheric, ecological and hydrological processes at relevant scales. With respect to influence of climate and human activities on mobilisation and river-borne transport of constituents, the main issues for the future are related to declining availability and quality of ground data for quantity and quality of water discharge. Such assessments presented in this paper, in combination with community wide science evaluation, has lead to an update of the science agenda for BAHC, a summary of which is provided in the appendix.

Here we report a microstructural analysis of systematic defects and inclusions in carbonados from Brazil and the Central African Republic (CAR). Transmission electron microscopy (TEM) has revealed the presence of pervasive defect lamellae in both the CAR and Brazilian carbonados that are distinct from planar defects observed in synthetic polycrystalline diamond (PCD). Analyses of included minerals by energy dispersive spectroscopy (EDS) yielded strong evidence for metallic Fe, Ti, and Si, as well as SiC and Fe-Cr alloys, within the diamond matrix. Our results offer strong evidence for a close genetic relationship between Brazilian and Central African carbonados, suggesting formation within a united landmass during the late Archaean. The data do not preclude carbonado nucleation by meteoritic impact, though this issue remains contentious. The role of water in the growth of carbonado merits further exploration.

The Highborne Cay stromatolitic mats contain Schizothix as the dominant cyanobacterium and show millimeter-scale lamination: Some layers in the mat are soft (unlithified), whereas other layers are crusty (lithified). Lithified layers within the mats correspond to micritic horizons composed of thin (20-50 mu m) micritic crusts, which commonly overlie truncated, micritized carbonate sand grains. These features are identical to lithified laminae in the underlying stromatolite; the micritic crusts are similar in thickness to micritic laminae in many ancient stromatolites. Biogeochemical parameters in a representative stromatolitic mat from Highborne Cay were measured to identify the role of bacteria in precipitation and dissolution of CaCO (sub 3) . Depth distributions of O (sub 2) , HS (super -) , and pH were determined with microelectrode measurements in the field. Oxygen profiles were used to calculate photosynthesis and aerobic respiration. Sulfate reduction was determined using (super 35) SO (sub 4) (super 2-) and sulfide oxidation potential was measured in homogenized samples. Our results indicate that cyanobacterial photosynthesis, sulfate reduction, and anaerobic sulfide oxidation in stromatolitic mats at Highborne Cay are responsible for CaCO (sub 3) precipitation, whereas aerobic respiration and aerobic sulfide oxidation cause CaCO (sub 3) dissolution. A close coupling of photosynthesis and aerobic respiration in the uppermost few millimeters of the mats results in no, or very little, net lithification. Sulfur cycling, on the other hand, shows a close correlation with the formation of lithified micritic layers. Photosynthesis, combined with sulfate reduction and sulfide oxidation results in net lithification. Sulfate reduction rates are high in the uppermost lithified layer and, on a diel basis, consume 33-38% of the CO (sub 2) fixed by the cyanobacteria. In addition, this lithified layer contains a significant population of sulfide-oxidizing bacteria and shows a high sulfide oxidation potential. These findings argue that photosynthesis coupled to sulfate reduction and sulfide oxidation is more important than photosynthesis coupled to aerobic respiration in the formation of lithified micritic laminae in Highborne Cay stromatolites.

We present multidisciplinary research focusing on the Nanga Parbat Himalaya of northern Pakistan. Remote sensing of the subsurface includes radio-echo sounding to investigate glaciers, magnetotelluric sounding, and seismic tomography to investigate shallow to deep aspects of the lithosphere. Remote sensing of the landscape includes satellite image acquisition, multispectral analysis, geomorphometric analysis of a satellite-derived digital elevation model (DEM), and the application of GIS and pattern recognition procedures to analyze topographic complexity and the geomorphology of the mountain massif. Detailed mapping requires topographic normalization of satellite imagery using the non-Lambertian model. Radar measurement of thicknesses of glacier ice, coupled with assessment of satellite imagery and field data, have enabled calculation of ice and sediment discharge. Collectively, scientific observations reinforce prior understandings of rapid rates of uplift and high rates of surficial denudation. The integration of data has thus enabled a systematic approach to study localized coupling between tectonic and surface processes. In future studies of this kind, it will become ever more important for geoscientists to integrate quantitative remote sensing and GIS into a standard analytical framework in order to solve complex problems.

The importance of ground ice in the initiation and development of these features, and of large impact structures in controlling channel courses, has long been recognized. The development of the fretted channel systems, including the integration of closed canyons, craters, and surface depressions into throughgoing channels, has previously been attributed primarily to mass-wasting processes. The two channel systems in southern Ismenius Lacus quadrangle, Mamers Valles and Ismeniae Fossae, incorporate craters of probable impact origin, but both also include irregular crater-like features and scalloped channel reaches that have characteristics not consistent with an impact origin. Some of these are, by analogy with morphologically similar features on Earth and elsewhere on Mars, reasonably interpreted as of volcanic origin. The detailed morphologies of a few diagnostic features associated with Ismeniae Fossae suggest a hydrovolcanic origin, an inference supported by the probable presence of abundant ground ice or groundwater at the time of their formation. The evidence described here for hydrovolcanism supports the inference that, in addition to mass-wasting processes, explosive excavation, intrusion-driven sublimation, subsurface erosion, and erosion by running water may have played important roles in channel formation and evolution as well. All of these processes are consistent with magma interacting with groundwater or ground ice. Copyright 1998 by the American Geophysical Union.

The observed features include a velocity boundary layer in the solar wind that streams around the flanks of the Mars ionosphere and enhanced planetary particle fluxes detected when the solar wind speed decreases to low values within the boundary layer. It is suggested that a cold plasma flow is present in the tenuous Mars upper ionosphere and that its momentum is provided by the solar wind within the adjacent velocity boundary layer. Calculations are presented to estimate the momentum flux that is delivered to the Mars upper ionosphere. It is argued that an ionospheric flow can be driven by solar wind momentum transferred from a velocity boundary layer whose thickness is 100-200 km around the terminator. By comparison a dense early Mars ionosphere could have been eroded by the momentum flux delivered from a approximately 1000 km thick boundary layer which would be comparable to that present around the Venus ionosphere. The total mass loss eroded by this process through Martian history should have not been larger than that of a few meters-deep global layer of water. It is further suggested that the erosion of the Mars ionosphere is not axially symmetric around the terminator but should preferably occur over the magnetic polar regions of the ionosphere.

Valleys tend to originate (1) on Noachian to Early Hesperian (stages 1 and 2) large volcanoes, (2) within 50-100 km of stages 1 and 2 rift systems, and (3) within 100 km of Noachian (stage 1) impact craters >50 km in diameter. These geologic preferences explain observations of higher valley-source densities (VSDs) in areas of higher elevations and regional slopes (>1 degrees ) because the volcanoes, rifts, and craters form high, steep topography or occur in terrain of high relief. Other stage 1 and stage 2 high, steep terrains, however, do not show high VSDs. The tendency for valleys to concentrate near geologic features and the overall low drainage densities in Thaumasia compared to terrestrial surfaces rule out widespread precipitation as a major factor in valley formation (as is proposed in wann, wet climate scenarios) except perhaps during the Early Noachian, for which much of the geologic record has been obliterated. Instead, volcanoes and rifts may indicate the presence of shallow crustal intrusions that could lead to local hydrothermal circulation, melting of ground ice and snow, and groundwater sapping. However, impact-crater melt would provide a heat source at the surface that might drive away water, fonning valleys in the process. Post-stage 1 craters mostly have low nearby VSDs, which, for valleys incised in older rocks, suggests burial by ejecta and, for younger valleys, may indicate desiccation of near-surface water and deepening of the cryosphere. Later Hesperian and Amazonian (stages 3 and 4) valleys originate within 100-200 km of three young, large impact craters and near rifts systems at Warrego Valles and the southern part of Coprates rise. These valleys likely developed when the cryosphere was a couple kilometers or more thick, inhibiting valley development by hydrothermal circulation. However, eruption of groundwater may have occurred from impact-induced fracturing and lateral and perhaps minor upward transport of water due to seismic pumping. The two smaller craters formed along the plateau margin where the highest potential hydraulic head would occur in aquifers beneath the plateau. In the case of the larger crater (Lowell, 200 km in diameter), potential aquifers would likely be at depths of kilometers below the cryosphere. Seismic energy generated by the Lowell impactor would have been much greater, pumping both groundwater and perhaps fluidized slurry to the surface from beneath the cryosphere to form the young valleys and flow deposit. Along the margin of Thaumasia, tectonic pressurization of groundwater also may have contributed to valley formation. Dissection of rim materials of the Argyre impact may relate to tectonic activity and the unconsolidated state of basin ejecta. Copyright 1998 by the American Geophysical Union.

Several target options have been proposed, including sites that may harbor extant life and sites most likely to preserve evidence of past life. These sites have specific mineralogic characteristics. Extant life might be gathered around the sinters and associated mineral deposits of rare active fumaroles, or held within brine pockets and inclusions in a few evaporite-mineral deposits. Possibilities for fossilization include deltaic and lake-bottom sediments of once-flooded craters, sinters formed by ancient hot-spring deposits, and the carbonate deposits associated with some evaporite systems. However, the highly varied mineralogy of fossil occurrences on Earth leads to the inference that Mars, an equally complex planet, could host a broad variety of potential fossilizing deposits. The abundance of volcanic systems on Mars and evidence for close associations between volcanism and water release suggest possibilities of organism entrapment and mineralization in volcaniclastic deposits, as found in some instances on Earth. Thus the targets being considered for exploration include a wide variety of unique deposits that would be characterized by silica or various nonsilicate minerals. Beyond these "special" deposits and in the most general case, an ability to distinguish mineralized from uncemented volcanic detritus may be the key to success in finding possible fossil-bearing authigenic mineralogies. A prototype miniaturized X ray diffraction/X ray fluorescence (XRD/XRF) instrument has been evaluated with silica, carbonate, and sulfate minerals and with a basalt, to examine the capabilities of this tool in mineralogic and petrologic exploration for exobiological goals. This instrument, CHEMIN (chemical and mineralogical analyzer), is based on an innovative low-power X ray tube, transmission geometry, and CCD collection and discrimination of diffracted and fluoresced X rays. The ability to accumulate and integrate the entire circumference of each complete Debye diffraction ring compensates for poor powder preparations, as might be produced by robotic sampling systems. With CHEMIN, a wide range of minerals can be uniquely identified. Using Rietveld analysis of the XRD results, mineral quantification is also possible. Expanded capabilities in phase analysis and constrained data solutions using quantitative XRD and XRF are within reach.

Mineral identification on Mars will most likely be achieved through visible-infrared remote sensing in combination with other analyses on landed missions. Therefore, understanding the visible and infrared spectral properties of terrestrial samples formed via processes similar to those thought to have occurred on Mars is essential to this effort and will facilitate site selection for future exobiology missions to Mars. Visible to infrared reflectance spectra are presented here for the fine-grained fractions of altered tephra/lava from the Haleakala summit basin on Maui, the Tarawera volcanic complex on the northern island of New Zealand, and the Greek Santorini island group. These samples exhibit a range of chemical and mineralogical compositions, where the primary minerals typically include plagioclase, pyroxene, hematite, and magnetite. The kind and abundance of weathering products varied substantially for these three sites due, in part, to the climate and weathering environment. The moist environments at Santorini and Tarawera are more consistent with postulated past environments on Mars, while the dry climate at the top of Haleakala is more consistent with the current Martian environment. Weathering of these tephra is evaluated by assessing changes in the leachable and immobile elements, and through detection of phyllosilicates and iron oxide/oxyhydroxide minerals. Identifying regions on Mars where phyllosilicates and many kinds of iron oxides/oxyhydroxides are present would imply the presence of water during alteration of the surface material. Tephra samples altered in the vicinity of cinder cones and steam vents contain higher abundances of phyllosilicates, iron oxides, and sulfates and may be interesting sites for exobiology.

Recent models of the adsorption of H (sub 2) O at Mars-like conditions indicate that it adsorbs more poorly than previously believed. H (sub 2) O adsorption is a necessary proxy for peroxide adsorption; hence the adsorptive slowing of peroxide diffusion is modeled as less efficient. Because the peroxide has a finite lifetime, it has a finite extinction depth as well. The effects of regolith gardening by impacts are quantitatively estimated and combined with the effects of oxidation by atmospheric gases to produce estimates of the degree of oxidation of the Martian surface with depth. We explore the effects of different crater production populations along with variations in H (sub 2) O (sub 2) extinction depths, and hydrothermal oxidation of ejecta. In very select circumstances involving very early onset of oxidizing conditions during heavy bombardment, 150-200 m of regolith could be fully oxidized. More likely scenarios for the crater production population, onset of oxidizing conditions, and oxidant extinction depth yield estimates of no more than a few meters to putative reducing material. In addition, uncertainties remain regarding the degree to which hydrothermal or other high-temperature chemistry might oxidize materials in ejecta blankets. The trade-off between accessing unlithified sediments or rock interiors must be considered. Copyright 1998 by the American Geophysical Union.

The apparent degree by which shergottites are overrepresented among Martian meteorites is thereby reduced to about fourfold relative to other types of Martian meteorites for nominal cratering rate models, and further reduced for higher cratering rate models. If the shergottite-ejection event is assigned to one of three craters in the vicinity of Olympus Mons that were previously identified as candidate source craters for the SNC (shergottites, nakhlites, Chassigny) meteorites, and the nakhlite/chassignite event is assigned to a candidate crater in the vicinity of Ceraunius Tholus, the implied ages of the surrounding terrains agree well with crater density ages. Because of their young crystallization ages, the likely origin of the shergottites is in the Tharsis region even for cratering rates up to twice the nominal value (minimum terrain ages). For these higher cratering rates, the nakhlite source need not be in the Tharsis region. Since the source of the ancient orthopyroxenite, ALH84001, was probably in the ancient southern uplands, meteorite-yielding impacts may have been widely dispersed on the Martian surface.

The influent streambeds to these basins are characterized by steep gradients and elevation head losses on average of 1 km. These closed basins and influent fluvial channels provide a foundation to investigate the processes under which water was transferred among the early Martian atmosphere and groundwater reservoirs. Channel gradients reflect basin-controlled water table conditions, and the channel head losses suggest sustained drawdowns within the basins due to evaporation and/or sublimation-induced pumping of groundwater. Finite element modeling of groundwater flow permits estimation of minimum rates for evaporation/sublimation for a reasonable set of boundary conditions and hydraulic conductivities, and suggests a Noachian environment with a minimum of 10-20 cm/yr of evaporation and/or sublimation. The flow models are unable to be reconciled with channel gradients without introduction of local precipitation. Acceptable solutions are found with a minimum of 1 - 2 cm/yr of groundwater recharge.

The experiments are designed to illustrate the dominant features of monsoon response to SST and GW forcings and to delineate the relative importance of each forcing function in contributing to the variability of the monsoon. Results indicate that ocean basin-scale SST anomalies exert a stronger control on the interannual variability of the monsoon compared to GW anomalies. The impact of SST anomalies on the monsoon appears nonlinear with respect to warm and cold events. The monsoon is weakened during the warm events but changes less noticeably during the cold events. The diminution of monsoon circulation associated with the warm SST anomalies is accompanied by a broad-scale reduction in water vapor convergence and monsoon rainfall. Results also indicate that, following wet land surface conditions (enhanced snow and soil moisture) in the continent during previous cold seasons, the summer monsoon becomes moderately weaker. Antecedent land surface processes mainly influence the early part of the monsoon. Wetter and colder conditions occur in the Asian continent during warm SST events. This results in reduced land-sea thermal contrast, which reinforces the weak monsoon anomalies produced initially by warm SST forcing. These interactive forcings are also responsible for the changes in the winter-spring westerlies over subtropical Asia, which are key precursory signals for the subsequent summer monsoon. It should be pointed out that this study is conducted for the climate decade of 1979-88 only. The general robustness of the results needs to be explored by further investigations. In addition, chaotic features may have affected the results because of sampling errors.

This investigation tested the hypothesis that P. lanceolata gall formation was caused by the associated eubacterium using a species-specific rDNA probe (S-S-P.l.sym-0949-a-A-25) to identify and assay for symbiont presence during consecutive laboratory induction trials. Gall induction was quantified and whole-cell in situ hybridization used to determine the relative percentage of symbiotic eubacteria in inoculation homogenates. In situ hybridization of symbionts in sections allowed localization and monitoring of this microbe during gall development. Induction trial results indicate a significant correlation between bacterial symbiont presence and gall initiation (P = 0.00005). The gall bacterium comprised the majority of the eubacteria hybridized in laboratory induction homogenates (85-97%), in galls induced in the laboratory and in three algal populations in nature. The evidence presented here demonstrates the causative role of the identified eubacterium in gall induction and formation. This investigation is significant in the application of molecular methods towards understanding the roles of noncultivable marine bacteria in marine algal-microbe interactions.

A smoke aerosol physical and optical model is developed from a database of over 800 volume size distributions inverted from sky radiance data measured by the AERONET radiometer network in Brazil over a 3-year period. The model represents total column, ambient conditions during the burning season in the Amazon Basin and cerrado region of Brazil. The mean volume size distributions are bimodal and can be represented by two lognormals. Accumulation mode modal radius is 0.13 plus or minus 0.02 mu m with sigma = 0.60 plus or minus 0.04, and coarse-mode modal radius ranges from 6 to 40 mu m, with a mean of 11.5 mu m and sigma = 1.26 plus or minus 0.23. The volume of each mode varies with optical thickness, causing the ratio of accumulation mode and coarse mode to vary as well, but the effect on the optical properties is negligible. Refractive index is taken to be 1.43-0.0035i, and single scattering albedo is assumed to be 0.90, which is modeled with an external mixing of black carbon. The optical properties in the visible are dominated by the accumulation mode. Accumulation mode characteristics do not vary from year to year, from forest to cerrado region, with optical thickness or with precipitable water vapor. At one test location, accumulation mode characteristics do vary with air mass trajectory origin. The model is tested with independent data and can accurately predict the scattering phase function and path radiance in the backscattering direction that determines remote sensing properties and is responsible for scattering sunlight back to space.

Anesthetics exhibit greatly enhanced concentrations at these interfaces, compared to nonanesthetics. The substitution of the interfacial solubilites of the anesthetics for their bulk lipid solubilities in the Meyer-Overton relation, was found to give a better correlation, indicating that the potency of an anesthetic is directly proportional to its solubility at the interface.

AN - 85410544; pmid-9865081 AB - In two experiments, we examined the possibility that the human vestibulo-ocular reflex (VOR) is subject to dual adaptation (the ability to adapt to a sensory rearrangement more rapidly and/or more completely after repeated experience with it) and adaptive generalization (the ability to adapt more readily to a novel sensory rearrangement as a result of prior dual adaptation training). In Experiment 1, the subjects actively turned the head during alternating exposure to a visual-vestibular rearrangement (target/head gain = 0.5) and the normal situation (target/head gain = 0.0). These conditions produced both adaptation and dual adaptation of the VOR but no evidence of adaptive generalization when tested with a target/head gain of 1.0. Experiment 2, in which exposure to the 0.5 gain entailed externally controlled (i.e., passive) whole body rotation, resulted in VOR adaptation but no dual adaptation. As in Experiment 1, no evidence of adaptive generalization was found.

AN - 79638372; 11542663 AB - Differences in the isotope content of the biogenous chemicals of cosmonaut habitats are given a theoretical consideration. Rationale is given to the hypothesis according to which the biochemical and biophysical processes in plants. animals, and humans must be impacted by the isotopes of all the biogenous chemicals in cosmonaut habitats. Organisms were found to persistently make preference of lighter fractions of stable isotopes from the biogenous chemicals. In most of the compounds the light fraction of stable isotopes constitutes the greater portion by mass. However, the optimal isotope composition of biogenous chemicals is still unknown and necessitates biochemical, toxicological, biological and other kinds of research. The functions of a life support system should also include production and maintenance of an optimal isotope composition for habitats, i.e. water, oxygen, food stuffs in order to improve metabolism in and performance of cosmonauts.

EPA (0.1 μM) improved postischmic contractile dysfunction of the ischemic/reperfused heart. EPA (10 μM) attenuated hypoxia/reoxygenation-induced morphological deterioration of cardiomyocytes. The results suggest the presence of direct cardioprotective effects of EPA. Rats were orally treated for 4 weeks with 1 g/kg/day of EPA-E to elucidate ex vivo effects of EPA, and the fatty acid composition of cardiac phospholipids was determined. The percent ratio of EPA in total fatty acids of cardiac phospholipids increased whereas that of arachidonic acid decreased. The percent ratio of n-3/n-6 fatty acid did not increase. Treatment with EPA-E did not improve the post-ischemic contractile function, but attenuated the ischemia/reperfusion-induced release of prostaglandins during reperfusion. Treatment with EPA-E preserved a better morphological appearance of the cardiomyocytes subjected to hypoxia/reoxygenation. The results suggest that the mechanisms responsible for cytoprotective effects of hypoxic/reoxygeanted cardiomyocytes or inhibition of metabolic alterations of the ischemic/reperfused heart by long-term EPA-E treatment did not contribute substantially to recovery of post-ischemic contractile dysfunction. The direct in vitro effects of EPA may play a role in the protection of the heart from ischemia/reperfusion or hypoxia/reoxygenation injury.[PUBLICATION ABSTRACT] JF - Molecular and Cellular Biochemistry AU - Takeo, Satoshi AU - Nasa, Yoshihisa AU - Tanonaka, Kouichi AU - Yabe, Kenichi AU - Nojiri, Michiko AU - Hayashi, Michihiko AU - Sasaki, Hideo AU - Ida, Kumiko AU - Yanai, Kyoko Y1 - 1998/11// PY - 1998 DA - Nov 1998 SP - 199 EP - 208 CY - New York PB - Springer Science & Business Media VL - 188 IS - 1-2 SN - 03008177 KW - Biology--Cytology And Histology KW - Prostaglandins KW - Eicosapentaenoic Acid KW - Norepinephrine KW - Fatty acids KW - Rodents KW - Cardiomyocytes KW - Ischemia KW - Hypoxia KW - Rats KW - Animals KW - Rats, Sprague-Dawley KW - Myocardial Ischemia -- drug therapy KW - Myocardium -- pathology KW - Cells, Cultured KW - Norepinephrine -- metabolism KW - Anoxia -- physiopathology KW - Prostaglandins -- metabolism KW - Myocardium -- metabolism KW - Myocardial Ischemia -- physiopathology KW - Male KW - Myocardial Reperfusion Injury -- physiopathology KW - Anoxia -- metabolism KW - Myocardial Ischemia -- metabolism KW - Myocardial Reperfusion Injury -- metabolism KW - Eicosapentaenoic Acid -- pharmacology UR - http://libproxy.lib.unc.edu/login?url=http://search.proquest.com/docview/756250474?accountid=14244 L2 - http://vb3lk7eb4t.search.serialssolutions.com/?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQ%3Ahealthcompleteshell&rft_val_fmt=info:ofi/fmt:kev:mtx:journal&rft.genre=article&rft.jtitle=Molecular+and+Cellular+Biochemistry&rft.atitle=Effects+of+long-term+treatment+with+eicosapentaenoic+acid+on+the+heart+subjected+to+ischemia%2Freperfusion+and+hypoxia%2Freoxygenation+in+rats&rft.au=Takeo%2C+Satoshi%3BNasa%2C+Yoshihisa%3BTanonaka%2C+Kouichi%3BYabe%2C+Kenichi%3BNojiri%2C+Michiko%3BHayashi%2C+Michihiko%3BSasaki%2C+Hideo%3BIda%2C+Kumiko%3BYanai%2C+Kyoko&rft.aulast=Takeo&rft.aufirst=Satoshi&rft.date=1998-11-01&rft.volume=188&rft.issue=1-2&rft.spage=199&rft.isbn=&rft.btitle=&rft.title=Molecular+and+Cellular+Biochemistry&rft.issn=03008177&rft_id=info:doi/10.1023%2FA%3A1006811009809 LA - English DB - ProQuest Central N1 - Copyright - Kluwer Academic Publishers 1998 N1 - Last updated - 2014-08-22 DO - http://dx.doi.org/10.1023/A:1006811009809 ER - TY - JOUR T1 - Congenital hydrocephalus caused by exposure to low level X-radiation at early gestational stage in mice. AN - 69262778; 11542485 AB - Hydrocephalus is a severe and often lethal birth defect in humans resulting from excess accumulation off cerebrospinal fluid (CSF) in the cranial vault, accompanied by enlargement of the head, prominence of the forehead and atrophy of the brain. A wide variety of teratogenic procedures have been used to obtain congenital hydrocephalus in laboratory animals. Radiation, infections, trypan blue, hypervitaminosis A, salisylates and nutritional deficiencies were considered as the teratogens. Several investigators induced congenital hydrocephalus following irradiation of pregnant animals. The purpose off this study is to elucidate the pathogenesis off congenital hydrocephalus induced by X-irradiation in mice. Since the sensitive period for malformations produced by X-radiation in mice ranges from gestational day 7 (G7) to Gl3.

Four types of microorganisms were recognized on the basis of size, morphology, and chemical composition. Some of the organisms mineralized rapidly, whereas others show no evidence of mineralization. Many mineralized cells are hollow and do not contain evidence of microstructure. Filaments, either attached or no longer attached to organisms, are common. Unattached filaments are mineralized and are most likely bacterial appendages (e.g., prosthecae). Features similar in size and morphology to unattached, mineralized filaments are recognized in martian meteorite ALH84001.

It was discovered that the data were collected in three separate missions during 1962 and 1963. The first two missions covered only the coastal areas, while the third mission covered the entire continent. Many of the 1782 frames collected were cloudy. This is especially true of West Antarctica. An optimal set of photographs covering the entire Antarctic coastline is identified along with some examples that show changes in the coastline which have occurred since the early 1960s.

The chief danger was presented by globally distributed ejecta, including transient thick rock vapor atmospheres. On Earth, much of the thermal radiation is absorbed by boiling the oceans. Any surviving life is either in deep water or well below the surface. Global thermal excursions are buffered by the heat capacity of the oceans. But when impacts are large enough to vaporize the oceans (>l0 (super 28) J), thermal buffering serves only to prolong the disaster for thousands of years, while the oceans rain out. Without oceans, thermal buffering does not occur on Mars. Relatively small impacts (10 (super 26) J) frequently heat the surface everywhere to the melting point. However, owing to the low Martian escape velocity, the most energetic ejecta (including the rock vapor) more easily escape to space, while massive quantities of less energetic ejecta are globally distributed Survival in deep subsurface environments is more likely on Mars because (1) Mars' lower background heat flow and lower gravity allow deeper colonies, and (2) the thermal heat pulse from a major impact is briefer. Only thermophile organisms could have survived impacts of asteroids large enough to leave heat or boil the entire terrestrial ocean. Studies of terrestrial microorganisms indicate that the last common ancestor may have been thermophile and the survivor of such a catastrophe. This organism should be distinguished from the first common ancestor. An additional refugium is ejection of rock to space by impacts and thier return to a habitable planet.

To explain the wide range of implied cooling rates, we consider forced convection as a dominant cooling process in lava tubes and present solutions that express mean temperature versus distance down the tube as a function of flow rate and flow cross section. Our models treat forced convective thermal losses in steady laminar flow through a lava tube with constant temperature walls and constant material properties. We explore the effects of different wall temperature and heat flux rate boundary conditions for circular tube and parallel plate flows over a range of tube sizes, plate spacings, eruption temperatures, and volume flow rates. Results show that nonlinear cooling rates over distance are characteristic of constant wall temperature for a piecewise parallel plate/circular tube model. This provides the best fit to temperature observations for Hawaiian tubes. Such a model may also provide an explanation for the very low ( approximately 10 degrees C) cooling observed in approximately 10 km long Hawaii tube flows and inferred in longer approximately 50 to 150 km tube-fed flows in Queensland. The forced convective cooling model may also explain similar flow morphologies for long tube-fed basaltic lava flows in a wide variety of locations, since small variations in eruption temperature or flow rate can accommodate the entire range of flow lengths and cooling rates considered. Our results are consistent with previous suggestions that long basaltic flows may be a reflection of low slopes, a particularly steady moderate eruption rate, and well-insulated flow, rather than of high discharge rates.

Significant increases of ozone concentrations in the lower atmosphere, or troposphere, and decreases in the upper atmosphere, or stratosphere, have been attributed to man-made causes. High ozone concentrations in the troposphere pose a health hazard to plants and animals and can add to global warming. On the other hand, ozone in the stratosphere serves as a protective barrier against strong ultraviolet (UV) radiation from the sun. Man-made CFC's (chlorofluorocarbons) act as a catalyst with a free oxygen atom and an ozone molecule to produce two oxygen molecules therefore depleting the protective layer of ozone in the stratosphere. The beneficial and harmful effects of ozone require the study of ozone creation and destruction processes in the atmosphere. Therefore, to provide an accurate model of these processes, an ozone lidar system must be able to be used frequently with as large a measurement range as possible. Various methods can be used to measure atmospheric ozone concentrations. These include different airborne and balloon measurements, solar occulation satellite techniques, and the use of lasers in lidar (high detection and ranging,) systems to probe the atmosphere. Typical devices such as weather balloons can only measure within the direct vicinity of the instrument and are therefore used infrequently. Satellites use solar occulation techniques that yield low horizontal and vertical resolution column densities of ozone.

Recent aircraft data obtained over the central US show that mineral aerosols were abundant in the upper troposphere during spring. Chemical reactions on mineral dust may provide an important sink for nitric acid. In regions where the mineral dust abundance is low in the upper troposphere similar HNO sub(3) removal processes may occur on biomass burning aerosols. We propose that mineral and biomass burning aerosols may provide an important global sink for gas phase nitric acid, particularly during spring and summer when aerosol composition in the upper troposphere may be greatly affected by dust storms from east Asia or tropical biomass burning plumes.

The Earth Observing System (EOS) Moderate Resolution Imaging Spectroradiometer (MODIS) is a 36-channel system that will be launched on the EOS-AM-1 platform in 1999. A vegetation-density map derived from integrated reflectances (R sub(i)), from MAS data, is compared with an independently-produced vegetation type and density map derived from Thematic Mapper (TM) and ancillary data. The maps agreed to within 13%, thus corroborating the effectiveness of using the reflectance technique for mapping vegetation density. Snow cover was mapped on a 13 April 1995 MAS image, using the original MODIS prototype algorithm and an enhanced MODIS prototype algorithm. Field measurements revealed that the area was completely snow covered. With the original algorithm, snow was mapped in 96% of the pixels having <50% vegetation-cover density according to the R sub(i) map, while in the areas having vegetation-cover densities greater than or equal to 50%, snow was mapped in only 71% of the pixels. When the enhanced MODIS snow-mapping algorithm was employed, 99% of the pixels having <50% vegetation-cover density were mapped, and 98% of the pixels with greater than or equal to 50% vegetation-cover density were mapped as snow covered. These results demonstrate that the enhanced algorithm represents a significant improvement over the original MODIS prototype algorithm especially in the mapping of snow in dense vegetation. The enhanced algorithm will thus be adopted as the MODIS at-launch snow-cover algorithm. Using this simple method for estimating vegetation density from pixel reflectance, it will be possible to analyze the accuracy of the MODIS snow-cover algorithm in a range of vegetation-cover in places where information on vegetation-cover density is not available from ground measurements.

The samples were analyzed for carbon dioxide (CO sub(2)), carbon monoxide (CO), hydrogen (H sub(2)), methane (CH sub(4)), a total nonmethane hydrocarbons (TNMHC). CO sub(2)-normalized mean emission ratios (ERs) and emission factors (g product/k fuel burned) were determined for CO sub(2), CO, H sub(2), CH sub(4), and TNMHC. Carbon monoxide production was determined to increase during high-intensity crowning. Unlike CO, a corresponding increase in the production of H sub(2), CH sub(4), and TNMHC during crowning was not detected. This represents the first clear indication that we know of where relative increases in CO production from vegetation fires are not positively correlated with corresponding increases in CH sub(4), H sub(2), and TNMHC production. These results may be important to the atmospheric carbon budget, and to the potential use of CO as a normalizing parameter for boreal forest fire emissions.

AN - 79636251; 11543262 AB - The mechanisms of biological effect of charged particles in space was studied through the inactivation effect of very low-density charged particles on very low-density cells at different impact parameters. A small type of microbeam facility with alpha-radioactive source and CN track detector were used. A diploid wild type Saccharomyces cerevisiae served as experimental eukaryotic cell. The correlation between cell inactivation and impact parameter of alpha-particles on cells was obtained through a CCD-camera system. The results showed that inactivation range of 1.13 MeV/u alpha-particles on cell-agarose mixture was about 5.5 micrometers, larger than the sum (about 3.l micrometers) of ion track-penumbra radius and yeast cell radius. The cell inactivation rate was 0.36-0.33. It suggests that multi-hit on a cell is necessary for killing it. However, in case of miss, the inactivation rate may not be zero at certain impact parameters.

AN - 79633223; 12212618 AB - Pregnant rats were exposed to 2.0, 2.25 or 2.5 Gy X-irradiation on gestation day 21. Pups were sacrificed 12 hr after exposure, and on postnatal day 5 (P5), P7 and P9. Their cerebella were observed immunohistochemically using anti-inositol 1,4,5 triphosphate (IP3) receptor antibody to identify Purkinje cells. These cells were disturbed to migrate and remained in the internal granular layer and white matter of the cerebellum. They had short dendrites, and some showed an abnormal direction of dendrites in rats exposed to 2.25 or 2.5 Gy. Alignment of Purkinje cells was also disturbed when examined either on P5, P7 or P9 especially by doses of 2.25 and 2.5 Gy. There was a relationship between X-ray doses and the number of cells piling up in the Purkinje cell layer of the cerebellum. The dose-response relationship with the number of ectopic Purkinje cells was noted in the anterior lobes of the cerebellum.

AN - 69974022; 9781922 AB - Recent in vitro evidence shows a role of endothelial nitric oxide (NO) in the modulation of isoproterenol-induced vasorelaxation. To elucidate roles of endothelial cells and NO in cyclic adenosine monophosphate (cAMP)-mediated vasodilators we examined the effects of removal of endothelium and a NO synthase (NOS) inhibitor on relaxant responses in vitro of rat aortic strips to beta-adrenoceptor stimulants and colforsin dapropate, a water-soluble forskolin, and changes in cAMP and cyclic guanosine monophosphate (cGMP) contents. Relaxant responses of rat aorta to isoproterenol, denopamine, salbutamol, colforsin, and dibutyryl cAMP (dbcAMP) were blunted by removal of endothelial cells or treatment with NOS inhibitor N(G)-nitro-L-arginine methyl ester (L-NAME). Relaxant response of endothelium-intact segments to isoproterenol was associated with increases in tissue cAMP and cGMP contents. Removal of endothelium or treatment with L-NAME markedly reduced basal cGMP and abolished the isoproterenol-induced increase in cGMP but not cAMP content. In endothelium-removed segments, pretreatment with sodium nitroprusside (SNP) restored the diminished relaxant response to isoproterenol and increased basal cGMP (from 0.08 +/- 0.01 to 0.16 +/- 0.02 pmol/mg protein), whereas it did not affect the isoproterenol-induced increase in cAMP. The diminished relaxant response of endothelium-removed segments to dbcAMP was not restored by SNP pretreatment. The results suggest that relaxant response of rat aorta to cAMP-mediated vasodilators is mediated, in part, by NO production in endothelium and subsequent increase in cGMP in vascular smooth-muscle cells.

It is probable that these polymers played an important role in the early stages of chemical evolution. Nevertheless, their full structural characterization has still not been accomplished. A number of mass spectrometric methods have now been applied to this structural problem including FAB-MS, thermal desorption EI-MS, ESI-MS, APCI-MS and off-line TMAH thermochemolysis/GC-MS. This latter method causes bond cleaveage and in situ methylation producing a suite of products which provides valuable insight into the substructural features of HCN polymers and also promises to serve as a sensitive diagnostic tool for detecting the presence of HCN polymers in samples from diverse sources.

AN - 69255890; 11541946 AB - The gynophore of the peanut plant (Arachis hypogaea) is a specialized organ that carries and buries the fertilized ovules into the soil in order for seed and fruit development to occur underground. The rates of growth of vertically and horizontally oriented gynophores were measured using a time-lapse video imaging system. We found that the region of maximum extension growth due to elongation (termed the Central Elongation Zone) is located on average at 2-5 mm from the tip. In the first 0-4 h after horizontal reorientation (gravistimulation), new zones of growth emerge on the upper surface, while the elongation zone of the lower side decreases in size and magnitude. Four to six hours after reorientation the zones of maximum growth are almost equal in size and location on the upper and lower sides. The growth rate and the gravitropic response decreased dramatically, upon the excision of the ovule region (terminal 1.5 mm), but a gravitropic growth response could be restored by applying the auxin indole-3-acetic acid exogenously to the excised tip. The addition of napthylphthalamic acid (an auxin transport inhibitor) at the ovule region allowed some growth to occur, but the gynophores do not respond normally to gravity, upon horizontal reorientation.

Anthropogenic greenhouse gases (GHGs), which are well measured, cause a strong positive (warming) forcing. But other, poorly measured, anthropogenic forcings, especially changes of atmospheric aerosols, clouds, and land-use patterns, cause a negative forcing that tends to offset greenhouse warming. One consequence of this partial balance is that the natural forcing due to solar irradiance changes may play a larger role in long-term climate change than inferred from comparison with GHGs alone. Current trends in GHG climate forcings are smaller than in popular "business as usual" or 1% per year CO2 growth scenarios. The summary implication is a paradigm change for long-term climate projections: uncertainties in climate forcings have supplanted global climate sensitivity as the predominant issue.

These variations reflect the development of low-level southerly wind maxima (or jets) on a number of different timescales in association with distinct subcontinental and larger-scale phenomena. On the diurnal timescale, the TC moisture flux variations are tied to the development of the Great Plains low-level jet. The composite nighttime anomalies are characterized by a strong southerly moisture flux covering northeast Mexico and the southern Great Plains, and enhanced boundary layer convergence and precipitation over much of the upper Great Plains. The strongest jets tend to be associated with an anomalous surface low over the Great Plains, reflecting a predilection for periods when midlatitude weather systems are positioned to produce enhanced southerly flow over this region. On subsynoptic (2-4 days) timescales the TC moisture flux variations are associated with the development and evolution of a warm-season lee cyclone. These systems, which are most prevalent during the early part of the warm season (May and June), form over the central Great Plains in association with an upper-level shortwave and enhanced upper-tropospheric cross-mountain westerly flow. A low-level southerly wind maximum or jet develops underneath and perpendicular to the advancing edge of enhanced midtropospheric westerlies. The clash of anomalous southerly moisture flux and a deep intrusion of anomalous northerly low-level winds results in enhanced precipitation eventually stretching from Texas to the Great Lakes. On synoptic (4-8 days) timescales the TC moisture flux variations are associated with the propagation and intensification of a warm-season midlatitude cyclone. This system, which also occurs preferentially during May and June, develops offshore and intensifies as it crosses the Rocky Mountains and taps moisture from the Gulf of Mexico. Low-level southerly wind anomalies develop parallel to the mid- and upper-level winds on the leading edge of the trough. Widespread precipitation anomalies move with the propagating system with reduced rainfall occurring over the anomalous surface high, and enhanced rainfall occurring over the anomalous surface low. On still longer timescales (8-16 days) the variations in the TC moisture transport are tied to slow eastward-moving systems. The evolution and structure of the mid- and low-level winds are similar to those of the synoptic-scale system with, however, a somewhat larger zonal scale and spatially more diffuse southerly moisture flux and precipitation anomalies.

The deterministic algorithms both use the path-integrated attenuation (PIA), measured by the surface reference technique, as a constraint. One deterministic algorithm corrects the k-R relation, while the second corrects the Z-R relation. The stochastic algorithms are based on applying an extended Kalman filter to the reflectivity profile. One employs radar reflectivity only; the other additionally uses the PIA. The authors find that the stochastic algorithm, which uses the PIA, is the most robust algorithm with regard to incorrect assumptions about the drop size distribution (DSD). The deterministic algorithm that uses the PIA to adjust the Z-R relation is also fairly robust and produces rain rates similar to the stochastic algorithm that uses the PIA. The deterministic algorithm that adjusts only the k-R relation and the stochastic radar-only algorithm are more sensitive to assumptions about the DSD. It is likely that they underestimate convective rainfall, especially if the DSD is erroneously assumed to be appropriate for stratiform rain conditions.

A progression of methodologies beginning with single polarization studies and leading to both dual polarization and multiple frequency techniques are described. Continuing analysis of a nine year data set of satellite-derived surface moisture in Spain is ongoing. Preliminary results from this study appear to provide some evidence of long term desertification in certain parts of this region. The methodologies developed during these investigations can be applied to other regions, and have the potential for providing modellers with extended data sets of independently derived surface moisture for simulation and validation studies, and climate change studies at the global scale.

AN - 62304974; ED448038 AB - This educator's guide explains basic aeronautical concepts and provides a background in the history of aviation within the context of flight environment (atmosphere, airports, and navigation). The activities in this guide are designed to be uncomplicated and fun. They were developed by NASA Aerospace Education Services Program specialists who have successfully used them in countless workshops and student programs around the United States. The activities encourage students to explore the nature of flight and experience some real-life applications of mathematics, science, and technology. The guide begins with education standards and skills matrices for the classroom activities, a description of the NASA aeronautics mission, and a brief history of aeronautics. Activities are written for the educator and divided into three chapters: (1) Air; (2) Flight; and (3) We Can Fly, You and I. Each activity begins with objectives, education standards and skills, and background material for the subject matter. The activity continues with step-by-step instructions and associated graphics to help the educator guide students through the activity in the classroom. Each activity includes student pages, which are as simple as a graphic of the activity and as advanced as a work sheet. They are meant to supplement the educator's presentation, serve as reminders, and inspire students to explore their own creativity. Activities requiring step-by-step assembly include student pages that present the project in a way that can be understood by pre-literate students. Each chapter ends with a section listing suggested interdisciplinary activities.

The associated motion and mass redistribution will inevitably cause variations in the Earth's polar motion. The present paper studies the relation of NAO with interannual polar motion. Two monthly series for the period of 1964-1994 are employed: the NAO index (NAOI), which is used as a proxy to measure the intensity of NAO, and the polar motion series. The latter is further processed to obtain the interannual polar motion excitation function psi by deconvolution and subsequent removal of the drift, the seasonal terms and short period variations. The time-domain cross correlation and frequency-domain coherence studies show significant correlations between NAOI and psi , especially on the x-component of psi as anticipated from the general pattern of NAO. This suggests possible significant contribution of NAO in exciting interannual polar motion.

The method, called the anomaly attenuation rate (AAR) method, involves computing radial averages of AARs with increasing distances from a range of assumed source centers. For well-isolated magnetic anomalies from "semi-compact" sources, the theoretical AARs range from approximately 2 (close to the sources) to approximately 3 (in the far-field region); the corresponding theoretical range of AARs for gravity anomalies is approximately 1 to approximately 2. When the estimated source centroid is incorrect, the AARs either exceed or fall short of the theoretical values. The levelling-off of the far-field AARs near their theoretical maximum values indicates the upper (deeper) bound of the centroid location. Similarly, near-field AARs lower than the theoretical minimum indicate the lower (shallower) bound of the centroid location. It is not always possible to determine usable upper and lower bounds of the centroids because the method depends on characteristics of sources/anomalies and the noise level of the data. For the environmental magnetic examples considered in this study, the determined deeper bounds were within 4% of the true centroid-to-observation distance. For the case of the gravity anomaly from the Bloomfield Pluton, Missouri, USA, determination of only the shallower bound of the centroid location ( approximately 7 km) was possible. This estimate agrees closely with the centroid of a previously determined three-dimensional model of the Bloomfield Pluton. For satellite magnetic anomalies, the method is appropriate only for high-amplitude, near-circular anomalies due to the inherent low signal-to-noise ratio of satellite magnetic anomalies. Model studies indicate that the AAR method is able to place depths within + or -20-30 km of actual center locations from a 400-km observation altitude. Thus, the method may be able to discriminate between upper crustal, lower crustal, and mantle magnetic sources. The results from the prominent Kentucky anomaly are relatively well-resolved (centroid depth approximately 30 km below the Earth's surface). For the Kiruna Magsat anomaly, the deleterious effects from neighboring anomalies make a determination difficult (possible depth could be between 20 and 30 km). The centroid depths are deeper for the Kursk anomaly ( approximately 40-50 km). These depths may indicate that magnetic anomalies from the near-surface Kursk iron formations (a known contributor) and deep crustal magnetic sources could combine to form the Kursk Magsat anomaly.

WEGENER currently has three scientific objectives which are related to plate-boundary processes, sea-level and height changes, and postglacial rebound. In a full exploitation of the space-geodetic techniques, namely SLR, VLBI and GPS, the individual scientific projects do not only pursue these objectives but also contribute to improving and developing the observation techniques as well as the modelling theories. In the past, particularly SLR observations within WEGENER-MEDLAS have provided a fundamental contribution to determine the regional kinematics of the tectonic plates in the Mediterranean with high precision. With GPS, spatially denser site distributions are feasible, and in several WEGENER projects detailed studies of tectonically active areas were possible on the basis of repeated episodic GPS observations. Current projects associated with WEGENER are successful in separating crustal movements and absolute sea-level variations as well as in monitoring postglacial rebound. These tasks require high-precision height determinations, a problem central to all of the present WEGENER activities. In these projects, continuously occupied GPS sites are of increasing importance. Time series of heights observed with continuous GPS can be determined with a few centimeters RMS error thus enabling the reliable estimates of vertical rates over relatively short time intervals. Regional networks of continuous GPS sites are already providing results relevant, for example, for the study of postglacial rebound. The Mediterranean area is an extraordinary natural laboratory for the study of seismotectonic processes, and the wealth of observations acquired in previous WEGENER projects together with new space-geodetic observations will allow the test of geophysical hypotheses linking three-dimensional deformations of the Earth's surface to the dynamics of the Earth's interior. In particular, it is anticipated that WEGENER projects will aim at a test of the slab-detachment hypothesis. The complex investigations on sea-level fluctuations presently carried out at basin scale from the Strait of Gibraltar to the Black Sea make it possible to study the present and recent past interactions of ocean, atmosphere and solid Earth, as well as to develop appropriate models to assess future aspects.

The CV3 (sub oxB) lithology is present in Bali, Kaba, parts of the Mokoia breccia and, possibly, in Grosnaja and Allan Hills (ALH) 85006. It is characterized by the presence of the secondary low-Ca phyllosilicates (saponite and sodium phlogopite), magnetite, Ni-rich sulfides, fayalite (Fa (sub 90) ), Ca-Fe-rich pyroxenes (Fs (sub 10-50) Wo (sub 45-50) ) and andradite. Phyllosilicates replace primary Ca-rich minerals in chondrules and CAIs, which suggests mobilization of Ca during aqueous alteration. Magnetite nodules are replaced to various degrees by fayalite, Ca-Fe-rich pyroxenes and minor andradite. Fayalite veins crosscut fine-grained rims around chondrules and extend into the matrix. Thermodynamic analysis of the observed reactions indicates that they could have occurred at relatively low temperatures (<300 degrees C) in the presence of aqueous solutions. Oxygen isotopic compositions of the coexisting magnetite and fayalite plot close to the terrestrial fractionation line with large Delta (super 18) O (sub fayalite-magnetite) fractionation ( approximately 20 per mil). We infer that phyllosilicates, magnetite, fayalite, Ca-Fe-rich pyroxenes and andradite formed at relatively low temperatures (<300 degrees C) by fluid-rock interaction in an asteroidal environment. Secondary fayalite and phyllosilicates are virtually absent in chondrules and CAIs in the CV3 (sub oxA) lithology, which is present in Allende and its dark inclusions, Axtell, ALHA81258, ALH 84028, Lewis Cliff (LEW) 86006, and parts of the Mokoia and Vigarano breccias. Instead secondary nepheline, sodalite, and fayalitic olivine are common. Fayalitic olivine in chondrules replaces low-Ca pyroxenes and rims and veins forsterite grains; it also forms coarse lath-shaped grains in matrix. Secondary Ca-Fe-rich pyroxenes are abundant. We infer that the CV3 (sub oxA) lithology experienced alteration at higher temperatures than the CV3 (sub oxB) lithology. The presence of the reduced and CV3 (sub oxA) lithologies in the Vigarano breccia and CV3 (sub oxA) and CV3 (sub oxB) lithologies in the Mokoia breccia indicates that all CV3 chondrites came from one heterogeneously altered asteroid. The metamorphosed clasts in Mokoia (Krot and Hutcheon, 1997) may be rare samples of the hotter interior of the CV asteroid. We conclude that the alteration features observed in the oxidized CV3 chondrites resulted from the fluid-rock interaction in an asteroid during progressive metamorphism of a heterogeneous mixture of ices and anhydrous materials mineralogically similar to the reduced CV3 chondrites.

Compositional gradients adjacent to the interface in both host and lamellae were formed by diffusion of chemical components into and out of the lamellae during cooling and growth. We have compared these gradients with compositional profiles calculated from diffusion and heat flow equations to estimate the cooling rate and burial depth of the sample. The resulting values for cooling rate and burial depth depend on which values are used for the diffusion rate of Ca in olivine, and how measured diffusivities are extrapolated to the lower temperatures at which the lamellae grew. If the highest diffusion coefficients are used, the cooling rates obtained from seven different lamellae range from 30 to 52 degrees C/year, with an average of 42 degrees C/year, and burial depths (assuming an overburden with a thermal diffusivity typical of solid rock) range from 14 to 17 m, with an average of 15 m. If the lowest reasonable diffusion coefficients are used, the cooling rates range from 1.4 to 2.2 degrees C/year, with an average of 1.7 degrees C/year, and the depths range from 68 to 83 m, with an average of 75 m. For the highest Ca diffusivities, details of the compositional profiles near the olivine/kirschsteinite interface suggest that continuous cooling was greatly accelerated at a temperature near 600-700 degrees C. The simplest physical explanation for such an acceleration is excavation of the sample from its original burial depth by an impact event. If Ca diffusivities are lower, a two-stage cooling history is not required.

AN - 52084468; 2002-057652 AB - This article discusses the history of the West Antarctic ice sheet including the amount of ice that has been lost by the ice sheet since the last glacial maximum 20,000 years ago, whether the sheets fringing ice shelves or its marine base make it inherently unstable, and whether the ice sheet was ever smaller during glacial minimums than it is today. Using evidence from diatoms identified from samples of the bed extracted from underneath 1000 meters of ice, it has been determined that during at least one recent minimum there was no ice at all in the present interior of West Antarctica. A recent reconstruction of the ice sheet in the Ross ice shelf during the last glacial maximum is discussed. The volcanic record suggests that a the West Antarctic ice sheet first appeared approximately 9 million years ago. Mass input to the West Antarctic ice sheet, mass budgets beneath the ice shelves and coupled atmosphere-ocean-ice global circulation models (GCM) are considered. Public education regarding ice sheet issues through the West Antarctic Ice Sheet program is considered.

The soil plots were wetted, and circularly polarized microwave measurements were made during the dry-down cycle. Soil profile temperature and profile moisture content were monitored continuously for the duration of the experiment. Laboratory analyses of soil physical properties such as texture and bulk density were conducted to aid theoretical calculations of the soil dielectric constants. Laboratory measurements of the soil dielectric constants were also made. Two commonly used soil dielectric models were compared. Theoretical values of soil dielectric constant were calculated with the Dobson model and the Wang-Schmugge model, and both compared reasonably well with laboratory measurements and also to values reported in the literature. Calculated soil emissivities derived from the field measurements also compared well with emissivities calculated from both the modeled dielectrics and those measured in the laboratory. Emissivities were compared with the average soil moisture for surface profiles of varying thickness. It was found that the observed effective penetration depth appeared to exceed the theoretically defined values. Copyright 1998 by the American Geophysical Union.

N1 - Last updated - 2011-12-13 ER - TY - JOUR T1 - Coverage Opportunities for Global Ocean Color in a Multimission Era AN - 17378420; 4561476 AB - The international community, recognizing the importance of global ocean color observations in the global carbon cycle, has proposed or flown six global ocean color missions over the next decade: the Ocean Color and Temperature Sensor (OCTS), Sea-viewing Wide Field-of-view Sensor (SeaWiFS), Moderate Resolution Imaging Spectrometer-AM (MODIS-AM), Medium Resolution Imaging Spectrometer (MERIS), Global Imager (GLI), and MODIS-PM. Each of these missions contains the spectral band complement considered necessary to derive oceanic pigment concentrations (i.e., phytoplankton abundance). This paper assesses whether assembling and merging data from these missions can improve ocean coverage, since clouds and sun glint prevent any single satellite from observing more than about 15% of the ocean surface in a single day, and whether new information about diel cycles of phytoplankton abundance is possible. Extensive numerical analysis, given the orbit and sensor characteristics of each mission, showed that merging data from three satellites can produce better ocean coverage in less time. Data from three satellites can improve coverage by 58% for a single day, including the obscuring effects of clouds and sun glint. Thus, observation of approximately 25% of the ocean can be provided, instead of only about 15-16% from a single satellite. After four days, approximately 62% of the ocean surface was observed, an increase from 43% observed by a single satellite. The addition of more satellites produced diminishing returns. Since the proposed missions have different orbits, they view the same location of the ocean at different times of day. This leads to the possibility of using data from the set of six missions to help understand diel phytoplankton dynamics. The missions produced colocated observations as much as 16 h apart in the high latitudes. However, given the distributions of land masses and ice cover, only a maximum of 14-h spacing could actually be achieved, and this only at high latitudes at the solstices. However, large differences of 4-10 h are readily available at other latitudes and in frequencies numbering in the tens of thousands at 20 degree latitude bands. This suggests that combinations of these missions can support new observations of the higher frequency dynamics of phytoplankton populations in the oceans and help determine how well observations taken at a single time represent the daily abundance.

The focus of this paper is on thin ice, which is more easily simulated in a laboratory environment. We summarize results of C-band scatterometer measurements and discuss how they may help in the interpretation of remote-sensing data. We compare the measurements with observations of thin ice from ERS and airborne radar data sets. We suggest that laboratory backscatter signatures should serve as bounds on the interpretation of remote-sensing data. We examine these bounds from the perspective of thin ice signatures, the effect of temperature, and surface processes, such as frost flowers and slush on these signatures. Controlled experiments also suggest new directions in remote-sensing measurements. The potential of polarimetric radar measurements in the retrieval of thickness of thin ice is discussed. In addition to the radar results, we discuss the importance of low-frequency passive measurements with respect to the thickness of thin ice.

SCSMEX is a major international field experiment to study the water and energy cycles of the Asian monsoon region, with the aim toward better understanding and improved prediction of the onset, maintenance, and variability of the monsoon of southern China, Southeast Asia, and the western pacific region. In this paper, the utility of reliable satellite data in revealing characteristics of the South China Sea (SCS) monsoon is emphasized. Using a combination of satellite-estimated rainfall, moisture, surface wind, and sea surface temperature, the authors present some interesting and hitherto unknown features in large-scale atmospheric and oceanic hydrologic processes associated with the fluctuation of the SCS monsoon. Results show that, climatologically, the SCS monsoon occurs during mid-May when a major convection zone shifts from the eastern Indian Ocean-southern Indochina to the SCS. Simultaneous with the SCS monsoon onset is the development of a moist tongue and frontal rainband emanating from the northern SCS, across southern China and the East China Sea to southern Japan, as well as the enhancement of equatorial convection in the western Pacific ITCZ. Analysis of the satellite-derived moisture and rainfall shows that the onset of the SCS monsoon during 1997 was preceded by the development of eastward-propagating supercloud clusters over the Indian Ocean. The satellite data also reveal a strong onset vortex over the SCS and large-scale cooling and warming patterns over the Indian Ocean and western Pacific. These features signal a major shift of the large-scale hydrologic cycle in the ocean-atmosphere system, which underpins the SCS monsoon onset. The paper concludes with a brief discussion of the observational platform of SCSMEX and a call for the use of satellite data, field observations, and models for comprehensive studies of the Asian monsoon.

A comparison of multitemporal data with the soils data revealed a direct correlation between changes in T sub(B) and soil water content, and soil texture. Regression relationships were developed for the ratio of percent sand to percent clay (RSC) and effective saturated hydraulic conductivity (K sub(sat)) in terms of T sub(B) and soil water content change. Validation of results indicated that both RSC and K sub(sat) can be estimated with adequate accuracy. The relationships are valid for the region with small variation of soil, organic matter content, soils with fewer macropores, and limiting experimental conditions. However, the findings have potential to employ microwave remote sensing for obtaining quick estimates of soil properties over large areas.

Because highly attenuated radar returns yield unreliable estimates of the rain rate, these are eliminated by means of a proxy variable. Q, derived from the apparent radar reflectivity factors and a power law relating the attenuation coefficient and the reflectivity factor. In determining the probability distribution function of areawide rain rates, the elimination of attenuated measurements at high rain rates and the loss of data at light rain rates, because of low signal-to-noise ratios, leads to truncation of the distribution at the low and high ends. To estimate it over all rain rates, a lognormal distribution is assumed, the parameters of which are obtained from a nonlinear least squares fit to the truncated distribution. Implementation of this type of threshold method depends on the method used in estimating the high-resolution rain-rate estimates (e.g., either the standard Z-R or the Hitschfeld-Bordan estimate) and on the type of rain-rate estimate (either point or path averaged). To test the method, measured drop size distributions are used to characterize the rain along the radar beam. Comparisons with the standard single-threshold method or with the sample mean, taken over the high-resolution estimates, show that the present method usually provides more accurate determinations of the area-averaged rain rate if the values of the threshold parameter, Q sub(T), are chosen in the range from 0.2 to 0.4.

Global maps of land surface properties, including snow cover, will be created from MODIS imagery. The MODIS snow-cover mapping algorithm that will be used to produce daily maps of global snow cover extent at 500 m resolution is currently under development. With the exception of cloud cover, the largest limitation to producing a global daily snow cover product using MODIS is the presence of a forest canopy. A Landsat Thematic Mapper (TM) time-series of the southern Boreal Ecosystem-Atmosphere Study (BOREAS) study area in Prince Albert National Park, Saskatchewan, was used to evaluate the performance of the current MODIS snow-cover mapping algorithm in varying forest types. A snow reflectance model was used in conjunction with a canopy reflectance model (GeoSAIL) to model the reflectance of a snow-covered forest stand. Using these coupled models, the effects of varying forest type, canopy density, snow grain size and solar illumination geometry on the performance of the MODIS snow-cover mapping algorithm were investigated. Using both the TM images and the reflectance models, two changes to the current MODIS snow-cover mapping algorithm are proposed that will improve the algorithm's classification accuracy in forested areas. The improvements include using the normalized difference snow index and normalized difference vegetation index in combination to discriminate better between snow-covered and snow-free forests. A minimum albedo threshold of 10% in the visible wavelengths is also proposed. This will prevent dense forests with very low visible albedos from being classified incorrectly as snow. These two changes increase the amount of snow mapped in forests on snow-covered TM scenes, and decrease the area incorrectly identified as snow on non-snow-covered TM scenes.

Results show that sea ice velocity is reproduced with relatively high accuracy (90% coherence, >80% normalized cross correlation) in models having high-quality atmospheric forcing fields (e.g., the European Centre for Medium-Range Weather Forecasts). On the other hand, temporal and spatial variability of the velocity field, as exemplified by progressive vector plots and ice deformation, respectively, are reproduced less accurately (coherence and normalized cross correlation <50%). In terms of model sensitivity, this means that deformation and temporal variability are more discriminating in terms of elucidating specifics about the constitutive relation and mechanical properties of sea ice on a large scale. For example, inclusion of both compressive and shear stresses is important in attaining a proper probability distribution of deformation relative to observations. Additional analysis shows that adjustments to specific model parameters improve the model results for either drift or select deformation components, but no best solution could be found, given the models examined here. Results suggest that inclusion of more physically based processes, such as subdaily tidal and inertial oscillations, reconsideration of the boundary layer formulation, and consideration of anisotropy, may be necessary to include in next-generation sea ice models, especially those that are intended for coupling with high-resolution (eddy resolving) ocean models.

Proteins have a reputation for being difficult to crystallize and high purity of the initial crystallization solution is considered paramount for success in the crystallization. Although little is written on the purifying capability of protein crystallization or of the effect of impurities on the various aspects of the crystallization process, recent published reports show that crystallization shows promise and feasibility as a purification technique for proteins. To further examine the issue of purity in macromolecule crystallization, this study investigates the effect of the protein impurities, avidin, ovalbumin, and conalbumin at concentrations up to 50%, on the solubility, crystal face growth rates, and crystal purity of the protein lysozyme. Solubility was measured in batch experiments while a computer controlled video microscope system was used to measure the {110} and {101} lysozyme crystal face growth rates. While little effect was observed on solubility and high crystal purity was obtained (>99.99%), the effect of the impurities on the face growth rates varied from no effect to a significant face specific effect leading to growth cessation, a phenomenon that is frequently observed in protein crystal growth. The results shed interesting light on the effect of protein impurities on protein crystal growth and strengthen the feasibility of using crystallization as a unit operation for protein purification.

K sub(m) values at in situ temperature were comparable to those observed by other investigators for a variety of aquatic environments. Competitive inhibition by dipeptides of a variety of amino acids showed that the aminopeptidases present were broadly specific; no strong tendency toward greater affinity for hydrophobic or hydrophilic amino acids was observed. Seawater cultures (1.0 mu m filtrate) were inoculated with a variety of monomeric organic compounds and incubated for 24 to 72 h prior to activity determination; histidine and phenylalanine were found to consistently inhibit aminopeptidase expression. It is hypothesized that auxotrophy for histidine and phenylalanine may be widespread in these assemblages, giving rise to high levels of constitutive, nonspecific aminopeptidase activity which results in significant respiration of the more common amino acids. Whatever the exact mechanism, aminopeptidase activity is strongly affected by the specific compounds present and not simply by the carbon-to-nitrogen ratio.

AN - 79631813; 11543240 AB - To study the mutagenesis of microorganism under space conditions, three Escherichia coli strains CSH108, A2 and A3, were flown on board the Chinese recoverable satellite (JB1 - B9611020) in Oct . 1996. Three ways of sample boarding were designed . After recovery, survival and frequency of lacI- mutation and Arg+ reversion were determined in the flight strains. The results showed that: E. coli strains could survive after the flight conditions. The lacI- mutation frequency of A3 strain in the biocabin was sixty - seven times that of the ground control, the Arg+ reversion frequency of CSH108 in the lead chamber, was ten times that of the ground control; and among the revertants the mutation frequency of non-sense suppressor increased remarkably. The results indicate that the space conditions may greatly enhance the mutation frequency of certain genes in the microorganism and may provide an effective method for microorganism breeding.

AN - 79627446; 11543247 AB - In order to evaluate the changes of lipid peroxide response induced by free radical after intense noise exposure, levels of T-SOD and MDA in serum and GSH in blood of guinea pigs were determined. Sixty male adult guinea pigs were used. The narrow band noise was centered at 1000Hz with 100Hz band width 126 dB SPL. It was found: 1) SOD activity in serum increased after 5d exposure (P > 0.05), but decreased after 10d exposure (P > 0. 05); 2) contents of MDA in serum increased (P < 0.05) and contents of GSH in blood decreased with increase of exposure time (P < 0.01). It shows that the lipid peroxide response induced by free radicals increased after intense noise exposure and it is possible to use free radical scavengers and/or antioxidant in prevention and treatment of noise induced damage.

AN - 73900773; 9727089 AB - While dietary links to ischemic heart disease (IHD) and coronary heart disease (CHD) mortality have been studied for many years, the correlation has not clearly been resolved, especially for older populations. In this paper, a multi-country statistical approach involving 32 countries is used to find dietary links to IHD and CHD for various age groups aged 35+. For IHD, milk carbohydrates were found to have the highest statistical association for males aged 35+ and females aged 65+, while for females aged 35-64, sugar was found to have the highest association. In the case of CHD, non-fat milk was found to have the highest association for males aged 45+ and females aged 75+, while for females 65-74, milk carbohydrates and sugar had the highest associations, and for females aged 45-64, sugar had the highest association. A number of mechanisms have been proposed in the literature that might explain the milk carbohydrate or non-fat milk association. One of the most prominent theories is that animal proteins contribute to homocysteine (Hcy) production; however, milk more than meat lacks adequate B vitamins to convert Hcy to useful products. Lactose and calcium in conjunction with Hcy from consumption of non-fat milk may also contribute to calcification of the arteries.

Results are presented for exposures to the skin, ocular lens and bone marrow shielded by a nominal thickness of aluminum shielding, comparable to that provided by a spacesuit. The calculated curves of organ dose and dose equivalent versus time are parameterized using a Weibull functional form for the fitting equation. The fitting parameters are determined using least squares regression techniques. These results provide a useful starting point for the development of methods to predict the cumulative doses and times to reach various dose limits from a limited number of dose measurements early in a solar particle event.

AN - 69257367; 11541929 AB - Space radiation dosimetry measurements have been made on board the Space Shuttle. A newly developed active detector called "Real-time Radiation Monitoring Device (RRMD)" was used (Doke et al., 1995; Hayashi et al., 1995). The RRMD results indicate that low Linear Energy Transfer (LET) particles steadily penetrate around the South Atlantic Anomaly (SAA) without clear enhancement of dose equivalent and some daily periodic enhancements of dose equivalent due to high LET particles are seen at the lower geomagnetic cutoff regions (Doke et al., 1996). We also have been analyzing the space weather during the experiment, and found that the anomalous high-energy particle enhancement was linked to geomagnetic disturbance due to the high speed solar wind from a coronal hole. Additional analysis and other experiments are necessary for clarification of these phenomena. If a penetration of high-energy particles into the low altitude occurs by common geomagnetic disturbances, the prediction of geomagnetic activity becomes more important in the next Space Station's era.

The Cr (super 2+) /Cr (super 3+) in spinel-saturated experimental systems can be estimated based on a simple model of Cr solubility in basalt. Fe (super 3+) appears to suppress the presence of Cr (super 2+) in basaltic systems. We predict that, in Fe-free systems, all Cr is trivalent at log f (sub O2) = -3 (i.e., QFM+3 to QFM-4), whereas all Cr is trivalent at approximately Ni-NiO(QFM+1) in Fe-bearing systems. Cr (super 2+) predominates under redox conditions or =QFM, appropriate for most terrestrial or martian basalts) strongly covaries with the ratio of non-bridging oxygens to tetrahedrally coordinated cations (NBO/T) (Mysen 1983) and can be estimated using the equation D (super (ol/liq)) (sub Cr3+) = -0.39.NBO/T+1.29. This relationship appears to be valid over the entire pressure range of olivine stability, from 1 atm to 15 GPa. D (sub Cr2+) (i.e., < or =IW-1, appropriate for lunar and some asteroidal basalts) is sensitive to liquid composition and temperature and can be estimated using either D (super (ol/liq)) (sub Cr2+) = 0.24.D (super (ol/liq)) (sub Mg) -0.07 or D (super (ol/liq)) (sub Cr2+) = 0.66.[10.000/T(K)]-4.48. The 1/T equation is probably only valid at 1 atm pressure, but the D (sub Mg) equation may be useful at higher pressures as well. The Cr content of spinel-saturated liquids is a function of temperature, composition, and f (sub O2) . However, the Cr content of spinel-saturated liquids is buffered by spinel and is insensitive to the bulk Cr content of the system (e.g., Roeder and Reynolds 1991). Therefore, the Cr content of a crystallizing, spinel-saturated basalt cannot be modeled using Raleigh fractionation models.

In 1995, a new strategy for making geodetic measurements was implemented that included local residents in the measurement program, and in 1997, the program was expanded to include teachers and students at five high schools. For the inhabitants of Alaska, understanding the hazards and underlying physical processes associated with earthquakes has immediate personal relevance. Large earthquakes occur yearly, great earthquakes have occurred during the lifetime of many residents, and the weekly testing of the tsunami warning system in coastal towns is a reminder of the devastation caused by earlier tsunamis generated near Alaska and a cautionary note about future inundation.

Isothermal growth experiments were conducted at 1210 degrees C under f (sub O) (sub 2) conditions equivalent to the iron-wustite buffer, producing enstatite crystals (En (sub 80) Fe (sub 19) Wo (sub 01) ). REE were measured in the basaltic glass by EPMA, and in the enstatite by SIMS. The enstatite partition signature for LREE is steeper than for pigeonite, has a negative Eu anomaly relating to f (sub O) (sub 2) , and the dependence of partition coefficients on Al (sub 2) O (sub 3) content is linked to crystal structural constants.

Emissions of nitric oxide (NO) from the soils of this region are poorly known. In this study, we adapt the CASA model of terrestrial-ecosystem productivity and trace-gas emissions to make spatially gridded, monthly estimates of NO emissions from soils for a nine-state region of the southeastern United States. Gridded input data layers to the model include temperature, precipitation, solar surface radiation, soil texture, land cover, fertilizer sales by county, and normalized-difference vegetation index. Total N gas emissions are modeled as proportional to the rates of gross N mineralization and fertilizer N input. The relative proportional emissions of NO, N (sub 2) O, and N (sub 2) are determined by soil water content. The model estimates 126X10 (super 9) g NO-N/yr emitted from soils for the entire nine-state area. Agricultural soils emit two-thirds of the total but cover only approximately 17% of the land area. Highest NO emissions occur along the cultivated Mississippi River corridor, southern Alabama-Georgia, and the Carolina coastal plain. Simulated emissions fall within the range of commonly reported values for temperate forests and cultivated fields, and the regional estimates are probably accurate within a factor of 2. Compared to NO (sub x) emissions from industrial, transportation, and utility sectors, soil emissions are approximately 10% of total regional emissions. However, the soil source could be a significant fraction of local NO (sub x) in rural agricultural areas, where emissions from fertilized fields usually range from 300 to 900 mg NO-N.m (super -2) .yr (super -1) . Fertilizer management could be an effective O (sub 3) -abatement strategy in some rural agricultural areas, although this possibility and general uncertainties in the soil source of NO should not be grounds to delay other O (sub 3) -abatement strategies for the much larger, nonsoil NO (sub x) sources in the region.

Groundwater outflow increases with increasing intrusion volume and subsurface permeability and is relatively insensitive to intrusion depth and subsurface porosity within the range considered here. Hydrothermally-derived fluids can melt through 1 to 2 km thick ice-rich permafrost layers in several thousand years. Hydrothermal systems thus provide a viable alternative to rainfall for providing surface water for valley formation. This mechanism can form fluvial valleys not only during the postulated early warm, wet climatic epoch, but also during more recent epochs when atmospheric conditions did not favor atmospheric cycling of water. The clustered distribution of the valley networks on a given geologic surface or terrain unit of Mars may also be more compatible with localized, hydrothermally-driven groundwater outflow than regional rainfall. Hydrothermal centers on Mars may have provided appropriate environments for the initiation of life or final oases for the long-term persistence of life.

To verify the long-term reliability and performance of the VCD Urine Processor Assembly (UPA), life testing was performed at the Marshall Space Flight Center (MSFC) from January 1993 to April 1996. Two UPA'S, the VCD-5 and VCD-5A, were tested for 204 days and 665 days, respectively. The compressor gears and the distillation centrifuge drive belt were found to have operating lives of approximately 4,800 hours, equivalent to 3.9 years of operation on ISS for a crew of three at an average processing rate of 1.76 kg/h (3.97 lb/h). Precise alignment of the flex-splines of the fluids and purge pump motor drives is essential to avoid premature failure after about 400 hours of operation. Results indicate that, with some design and procedural modifications and suitable quality control, the required performance and operational life can be met with the VCD /UPA.

Transmittance function monitoring is a potentially new NDE technique being tested as a tool to detect, quantify, and locate damage on flexible structures. The technique has a large spatial range that is practical for detecting damage on large composite material structures such as a reusable launch vehicle. The Transmittance Function (TF) theory is based on structural dynamics principles that define how vibration at one point in a structure is related to a force at another point. This relationship is called the Frequency Response Function (FRF). A Transmittance Function (TF) is derived as the ratio of FRFs, and can detect damage because the FRFs change due to damage. If one excitation is used for the testing, the force does not need to be measured to compute the TF. In the damage detection procedure, the structure is subjected to wide-band vibration and TFs are computed between different accelerometers to detect changes in the structure, presumably due to damage. In the first year of the project the TF method was tested on a bolted panel, a curved panel, and beams, all made of fiberglass. It was shown that damage could be detected using low frequency vibration, 250 to 1,250 Hz. The technique is sensitive to damage, but it requires storage of historical or pre-damage TFs for the healthy structure. This would become a large data storage requirement for large structures. Thus one objective for the second year of the project was to eliminate the need to store historical data. The second year report gives details of how storage of historical data was eliminated. Further results of testing panel structures are also given.

The fast recession of Pine Island Glacier, predicted to be a possible trigger for the disintegration of the West Antarctic Ice Sheet, is attributed to enhanced basal melting of the glacier floating tongue by warm ocean waters.

This presentation focuses on advancements made pertaining to our laboratory prototype, specifically, toward the analysis and interpretation of measured solar absorption spectra. Topics will include processing of 'measured' spectra (i.e., spectral registration and drift correction) and simulation of 'true' spectra (i.e., atmospheric assumptions and instrument transfer function modeling), as well as subsequent comparisons and findings. Future developments will focus on incorporating other key elements into the prototype instrument, performing relevant laboratory and atmospheric testing, and developing methods for calibration. These activities, along with concurrent scientific studies and atmospheric field testing, will serve to demonstrate overall feasibility and provide technique validation for this instrumentation and may lead to a future space-based implementation.

Often, climate records are of short duration, gathered at locations different from the area to be simulated, or do not contain all the variables required by a given model. This paper addresses this problem for ecosystem simulation in Alaska with the development of a weather generator. The generator, called WGENAL, is based on the WGEN climate generator developed and validated in the 48 conterminous states. Because of the extreme variability of weather in Alaska that is not accommodated by the statistical metrics in the earlier model, a new climate generator was developed. WGENAL generates daily values of precipitation, maximum temperature, minimum temperature, solar radiation, and wind run. Precipitation is generated using a Markov chain-gamma model. A two-parameter gamma distribution is used to generate wind run. Temperatures and solar radiation are generated using procedures developed in the earlier study. Validation of the generator shows it provides adequate diurnal and seasonal weather records for Fairbanks.

AN - 79973019; 9650608 AB - It is a common practice to estimate the number of particle-track traversals per cell or cell nucleus as the product of the ion's linear energy transfer (LET) and cell area. This practice ignores the effects of track width due to the lateral extension of delta rays. We make estimates of the number of particle-track traversals per cell, which includes the effects of delta rays using radial cutoffs in the ionization density about an ion's track of 1 mGy and 1 cGy. Calculations for laboratory and space radiation exposures are discussed, and show that the LET approximation provides a large underestimate of the actual number of particle-track traversals per cell from high-charge and energy (HZE) ions. In light of the current interest in the mechanisms of radiation action, including signal transduction and cytoplasmic damage, these results should be of interest for radiobiology studies with HZE ions.

AN - 79634466; 11542640 AB - Human fibroblasts are a suitable model to investigate early and late radiation-induced damages because they are involved in most medical irradiation. Early damages of healthy tissue in the entrance channel of the beam and around the tumor are estimated on the basis of cell inactivation measurements (X-ray 250kV, 3.2 Gy/min.; carbon ions at 199 MeV/u, LET 16.2 keV/micrometer; carbon ions at 11MeV/u, LET 153.5 keV/micrometer). Late effects have been assessed by measuring premature differentiation and increased collagen secretion of fibroblasts. In the organism premature differentiation and increased collagen secretion are part of a fibrotic reaction due to a response of tissue cells (among fibroblasts) to primary parenchymal damage. 10 days after irradiation fibroblasts show a dose--and LET--dependent increased collagen secretion correlating with premature terminal differentiation.

AN - 79634069; 11543071 AB - The enrichment of F on Antarctic meteorites is the result of their exposure to the atmosphere, and its measurement allows a subdivision of the terrestrial age into a duration of exposure on the ice and the time a meteorite was enclosed by the ice. In many cases, the periods of surface exposure are only small fractions of the terrestrial ages of meteorites collected in Antarctica. The enrichment of F on the surfaces of Antarctic achondrites was investigated by means of nuclear reaction analysis (NRA): scanning proton beams with an energy of 2.7 and 3.4 MeV were used to induce the reactions 19F(p, alpha gamma)16O and 19F(p,p gamma)19F, respectively. Gamma signals proportional to the F content were measured. The following Antarctic achondrites were investigated: Martian meteorite ALH 84001; diogenite ALHA77256; the eucrites ALHA81011 and ALHA78132; and in addition, the H5 chondrite ALHA79025. For ALH 84001, our data indicate a period of exposure on the ice of 95% of its terrestrial age of 13 000 years.

AN - 79631645; 11543123 AB - A new type of continuously operating, in-situ, remotely monitored sensor is presented. The sensor is comprised of a thin film array of magnetostatically coupled, magnetically soft ferromagnetic thin film structures, adhered to or encased within a thin polymer layer. The polymer is made so that it swells or shrinks in response to the chemical analyte of interest, which in this case is pH. As the polymer swells or shrinks, the magnetostatic coupling between the magnetic elements changes, resulting in changes in the magnetic switching characteristics of the sensor. Placed within a sinusoidal magnetic field the magnetization vector of the coupled sensor elements periodically reverses directions, generating magnetic flux that can be remotely detected as a series of voltage spikes in appropriately placed pickup coils. one preliminary sensor design consists of four triangles, initially spaced approximately 50 micrometers apart, arranged to form a 12 mm x 12 mm square with the triangle tips centered at a common origin. Our preliminary work has focused on monitoring of pH using a lightly crosslinked pH sensitive polymer layer of hydroxyethylmethacrylate and 2-(dimethylamino) ethylmethacrylate. As the polymer swells or shrinks the magnetostatic coupling between the triangles changes, resulting in measurable changes in the amplitude of the detected voltage spirits.

AN - 79630402; 11542639 AB - Energy depositions by sparsely and densely ionizing radiation in the cellular DNA are responsible for deleterious radiobiological effects like the induction of chromosome aberrations or gene mutations. However, due to differences in the spatial pattern of energy deposition the action of densely ionizing radiation is quantitatively and qualitatively different from that of sparsely ionizing radiation. By the use of new molecular-biological techniques a deeper insight into the molecular events underlaying particle-induced genetic changes has been obtained. The present paper will attempt to give a brief overview of progress in chromosome and mutation studies, Furthermore, recent published data on delayed genetic effects of cellular exposure to ionizing radiation will be summarized.

AN - 79629547; 11543186 AB - A description is given of the design and implementation of a method to track the presence of air contaminants aboard a spacecraft using an accurate physical model and of a procedure that would raise alarms when certain tolerance levels are exceeded. Because our objective is to monitor the contaminants in real time, we make use of a state estimation procedure that filters measurements from a sensor system and arrives at an optimal estimate of the state of the system. The model essentially consists of a convection-diffusion equation in three dimensions, solved implicitly using the principle of operator splitting, and uses a flowfield obtained by the solution of the Navier-Stokes equations for the cabin geometry, assuming steady-state conditions. A novel implicit Kalman filter has been used for fault detection, a procedure that is an efficient way to track the state of the system and that uses the sparse nature of the state transition matrices.

AN - 79628346; 11542636 AB - Many studies have shown that the effectiveness of radiations of varying LET is similar when yields of dsb have been measured, despite large differences in biological response. Recent evidence has suggested however, that current techniques underestimate the yields of dsb. By monitoring the fragmentation of DNA over a wide range of fragment sizes ( 6 Mbp) by pulsed field electrophoresis, RBE values greater than 1.0 for radiations of around 100 keV/mm have been determined. The data provide evidence for the production of correlated breaks produced within cells as particle tracks traverse the nucleus. The highly ordered structure of DNA within mammalian cells may lead to clustering of breaks over distances related to the repeating unit structures of the chromatin. As well as these regionally damaged sites, a major contributor to radiation effectiveness will be the localised clustering of damage in the 1-20 bp region. A major effort is required to elucidate the relative importance of these levels of clustering and their importance in biological response.

AN - 79628223; 11542638 AB - The most challenging radiation in space consists of fully ionized atomic elements with high energy for which only the few lowest energy ions can be stopped in shielding materials. The health risk from exposure to these ions and their secondary radiations generated in shield materials is poorly understood since there are few human data and a systematic study in relevant animal model systems has not been made. The accuracy of risk prediction is described as the major limiting factor in the management of space radiation risk. The expected impact of systematic studies is examined using the limited available biological data and models. Given the limitations of current predictions, models must be developed that are able to incorporate the required fundamental scientific data into accurate risk estimates. The important radiation components that can be provided for laboratory testing are identified. The use of ground-based accelerator beams to simulate space radiation is explained and quantitative scientific constraints on such facilities are derived. Three facilities, one each in the United States, in Germany and in Japan, currently have the partial capability to satisfy these constraints.

AN - 79628168; 9668131 AB - Tobacco mosaic virus (TMV) derivatives that encode movement protein (MP) as a fusion to the green fluorescent protein (MP:GFP) were used in combination with antibody staining to identify host cell components to which MP and replicase accumulate in cells of infected Nicotiana benthamiana leaves and in infected BY-2 protoplasts. MP:GFP and replicase colocalized to the endoplasmic reticulum (ER; especially the cortical ER) and were present in large, irregularly shaped, ER-derived structures that may represent "viral factories." The ER-derived structures required an intact cytoskeleton, and microtubules appeared to redistribute MP:GFP from these sites during late stages of infection. In leaves, MP:GFP accumulated in plasmodesmata, whereas in protoplasts, the MP:GFP was targeted to distinct, punctate sites near the plasma membrane. Treating protoplasts with cytochalasin D and brefeldin A at the time of inoculation prevented the accumulation of MP:GFP at these sites. It is proposed that the punctate sites anchor the cortical ER to plasma membrane and are related to sites at which plasmodesmata form in walled cells. Hairlike structures containing MP:GFP appeared on the surface of some of the infected protoplasts and are reminiscent of similar structures induced by other plant viruses. We present a model that postulates the role of the ER and cytoskeleton in targeting the MP and viral ribonucleoprotein from sites of virus synthesis to the plasmodesmata through which infection is spread.

AN - 79624714; 11542635 AB - Radiobiological studies using heavy charged particles followed closely the development of accelerators to produce beams of ever-increasing energy, driven primarily by the aspirations of physicists and chemists interested in the structure of matter. An impressive share of this development took place at Berkeley, beginning with the invention of the cyclotron by Ernest Lawrence in 1930. There followed a series of cyclotrons, synchrotrons and linear accelerators, culminating in the BEVALAC, which provided the first source of very heavy ions (helium to argon) to be used clinically, beginning in 1975. Other early entrants (1950's-1960's) in the clinical use of heavy ion beams (protons only) included Uppsala, Harvard/MGH and several facilities in the USSR. During the 1970's negative pi-meson (pion) beams for clinical use were developed in the US (LAMPF), Switzerland (SIN/PSI) and Canada (TRIUMF). Although the first accelerator built primarily for medical use, the Crocker Medical Cyclotron, was completed at Berkeley in 1939 (it was used primarily to produce neutron beams) it was not until 1990 that the next clearly dedicated medical heavy ion facility went into operation: the 3-gantry proton synchrotron at Loma Linda. There are several reasons for this long hiatus: the long time required to complete clinical trials; the need to develop more economic and flexible accelerators and beam handling systems; the early discouraging clinical results obtained with neutron beams at Berkeley in the 1940's, before the dose response differences for early and late effects were fully understood. During the last decade or so there has been a rapid increase in the number of proton beam facilities; heavier ion beams are so far available only at HIMAC in Japan and GSI in Germany. Earlier studies with radioactive alpha-particle sources and plant cells had already shown, by the early 1930's that high LET radiations were biologically more effective than X-rays in producing damage in eukaryotes. The increased penetration of high energy particles from accelerators made it possible to carry out in vivo radiobiological studies in animals, and the publication by Puck of the first radiation survival response for cultured mammalian cells in 1956, provided another valuable tool for radiobiological studies. One of the earliest systematic studies of the dependence of RBE (relative biological effectiveness) and OER (oxygen enhancement ratio) on LET (linear energy transfer) was that by Barendsen in the early 1960's; he irradiated cultured human kidney cells with deuterium and alpha-particles, and showed that RBE reached a maximum at an LET of 100-200 keV/micrometer, the same LET at which the OER decreased to approximately 1.0. More recent studies (Belli, Folkard, etc.) show that the RBE 'peaks' at a LET which is particle-dependent (for protons, RBE maximum is at approximately 30 keV/micrometer), indicating that LET alone does not adequately define the microscopic energy deposition and its influence on biological effect. One of the complications with heavy ion and pion beams is the increase in RBE with depth in the stopping region. Cultured cell techniques were developed to accurately map these RBE changes, which were investigated at each of the heavy ion and pion facilities, allowing physical dose profiles to be shaped to compensate for the change in biological effectiveness. With the heavier ions, RBE is also dependent on dose and on the dose fractionation scheme used. In vivo systems are the most suitable for such measurements and a variety of normal tissue and tumour end-points has been employed for such studies. A review of the published RBE values for proton beams, 1975-1997, shows very good consistency between the various centres, with average in vivo and average in vitro values falling in the range 1.11-1.18. In this article we have, due to space limitations, only been able to review a representative fraction of the extensive literature on heavy ion radiobiology. We have arbitrarily limited our discussion to mammalian systems, except for a few very early experiments of historical interest.

AN - 79623783; 11542637 AB - It has recently been demonstrated experimentally that DNA damage induced by high LET radiation in mammalian cells is non-randomly distributed along the DNA molecule in the form of clusters of various sizes. The sizes of such clusters range from a few base-pairs to at least 200 kilobase-pairs. The high biological efficiency of high LET radiation for induction of relevant biological endpoints is probably a consequence of this clustering, although the exact mechanisms by which the clustering affects the biological outcome is not known. We discuss here results for induction and repair of base damage, single-strand breaks and double-strand breaks for low and high LET radiations. These results are discussed in the context of clustering. Of particular interest is to determine how clustering at different scales affects overall rejoining and fidelity of rejoining of DNA double-strand breaks. However, existing methods for measuring repair of DNA strand breaks are unable to resolve breaks that are close together in a cluster. This causes problems in interpretation of current results from high LET radiation and will require new methods to be developed.

AN - 69265726; 11542325 AB - The constant presence of gravity force in the evolution of life on Earth caused the adaptation for its pressure and dependence of growth and morphogenesis of high plants on gravity, and appearance of gravitaxises of unicellular organisms. The modern investigations demonstrated the ability even of prokaryotic organisms for sensitivity of gravity modifications Erdmann et al., 1997). Object of current investigation was siphonaceous alga Vaucheria sessilis with branching thallome without septs. Vaucheria does not demonstrate gravitropic reaction, and does not possess statolite-like structure. It is important to note that graviresponse of such kind of objects was under investigation for the first time. The definite structure of cytoskeleton permits the functions of cytoskeleton elements to be analyzed in course of graviresponse. Siphonaceous algae are new and promising objects in gravitational cell biology. This investigation was intended to compare the graviresponse of Vaucheria detected on different experimental models of modified gravity.

AN - 69261791; 11542329 AB - Astronauts are subjected to flight-induced physical and psychic reactions which may be health threatening in the long term. Stress is a basic component of space missions, where astronauts are confined in a reduced volume, live in a hostile environment, have limited contact with the rest of the world and undergo a severe work load. Chronic stress in microgravity stimulates the HPA (hypothalamo-pituitary-adrenal) axis in astronauts with consequent hypercortisolim. Stress also stimulates the autonomic nervous system. Both increased cortisol and adrenergic stimulation suppress the immune function. For these reasons we developed experiments to contemporaneously measure the autonomic, HPA-axis and immune function in space missions. All measures are made with non-invasive methods. Autonomic adaptation is measured by spectral analysis of ECG derived interval, arterial pressure and respiration. HPA-axis function is assessed by measuring cortisol, F-Testosterone and DHEA in saliva. Immune function is monitored by measuring cytokine production and Th1/Th2 balance in saliva. Till now these experiments were performed on the ground. On 1998-99 space experiments will be performed and space technologies will be set up in collaboration with DMR company (Varese), to allow astronauts to measure stress factors directly in space. I.R.C.E.A. research, sponsored by the Italian Space Agency and selected by ESA and NASA, is focused on conditions which influence health in space flight: in particular, stress and microbial contamination.

AN - 69256157; 11541740 AB - Flow injection analysis instrumentation and methodology for the determination of ammonia and ammonium ions in an aqueous solution are described. Using in-line solid phase basification beds containing crystalline media. the speciation of ammoniacal nitrogen is shifted toward the un-ionized form. which diffuses in the gas phase across a hydrophobic microporous hollow fiber membrane into a pure-water-containing analytical stream. The two streams flow in a countercurrent configuration on opposite sides of the membrane. The neutral pH of the analytical stream promotes the formation of ammonium cations, which are detected using specific conductance. The methodology provides a lower limit of detection of 10 microgram/L and a dynamic concentration range spanning three orders of magnitude using a 315-microliters sample injection volume. Using immobilized urease to enzymatically promote the hydrolysis of urea to produce ammonia and carbon dioxide, the technique has been extended to the determination of urea.

These factors, with the abundance and distribution of metal and troilite, are used to classify winonaites which are described in detail with many photomicrographs, modes, mineralogy (low-Ca pyroxene, olivine, Ca pyroxene, Fe, Fe-Ni-metal, with minor chromite, daubreelite, alabandite, schreibersite, graphite, K-feldspar and apatite), bulk major and trace element compositions, olivine and pyroxene analyses, and trapped and cosmogenic noble gases and their isotopes. The results show that winonaites are primitive achondrites that suffered limited partial melting, with brecciation and metamorphism of the precursor body. The precursor was probably chondritic unlike any known chondrite group. (super 39) Ar/ (super 40) Ar age determinations of samples of Pontlyfni, Winona and Mt Morris range 4400-4540 m.y.; cosmic ray exposure ages are approximately 20-80 m.y. Brecciation and metamorphism of the precursor body occurred early in the solar system.

Single-crystal lepidocrocite particles dehydroxylated to polycrystalline particles of disordered maghemite that subsequently transformed to polycrystalline particles of hematite. Essentially pure maghemite was obtained at 265 and 223 degrees C for the 3 and 300 h heating experiments, respectively. Its saturation magnetization (J (sub s) ) and mass specific susceptibility are approximately 50 Am (super 2) /kg and approximately 400 x 10 (super -6) m (sub 3) /kg, respectively. Because hematite is spectrally dominant, spectrally hematitic samples (i.e., a minimum near 860 nm and a maximum near 750 nm) also could be strongly magnetic (J (sub s) up to approximately 30 Am (super 2) /kg) from the masked maghemite component. Analyses by TEM showed that individual particles are polycrystalline with respect to both maghemite and hematite. The spectrally hematitic and magnetic Mh + Hm particles can satisfy the spectral and magnetic constraints for Martian surface materials over a wide range of values of Mh(Mh + Hm) either as pure oxide powders or (within limits) as components of multiphase particles. These experiments are consistent with lepidocrocite as the precursor of Mh + Hm assemblages on Mars, but other phases (e.g., magnetite) that decompose to Mh and Hm are also possible precursors. Simulations done with a copy of the Mars Pathfinder magnet array showed that spectrally hematitic Mh + Hm powders having J (sub s) equal to 20.6 Am (super 2) /kg adhered to all five magnets.

Using the Antarctic meteorite ALH 84001 spectroscopic properties of particulate ALH 84001 from 0.3 to 25 mu m correctly identify low-Ca pyroxene as the dominant mineralogy. Absorption bands due to electronic transitions of ferrous iron are observed at 0.94 and 1.97 mu m that are typical for low-Ca pyroxene. A strong, broad water band is observed near 3 mu m that is characteristic of the water band typically associated with pyroxenes. Weaker features near 4.8, 5.2 and 6.2 mu m are characteristic of particulate low-Ca pyroxene and can be distinguished readily from the features due to high-Ca pyroxene and other silicate minerals. The reflectance minimum occurs near 8.6 mu m for the ALH 84001 powder, which is more consistent with high-Ca pyroxene and augite than low-Ca pyroxene. The dominant mid-infrared (IR) spectral features for the ALH 84001 powder are observed near 9 and 19.5 mu m; however, there are multiple features in this region. These mid-IR features are generally characteristic of low-Ca pyroxene but cannot be explained by low-Ca pyroxene alone. Spectral feature from 2.5-5 mu m are typically associated with water, organics and carbonates and have been studied in spectra of the ALH 84001, split 92 powder and ALH 84001, splits 92 and 271 chip surfaces. Weak features have been identified near 3.5 and 4 mu m that are assigned to organic material and carbonates. Another feature is observed at 4.27 mu m in many surface spots and in the powder but has not yet been uniquely identified. Spectroscopic identification of minor organic and carbonate components in this probable piece of Mars suggests that detection of small amounts of organics and carbonates in the Martian surface regolith would also be possible using visible-infrared hyperspectral analyses. Laboratory spectroscopic analysis of Martian meteorites provides a unique opportunity to identify the spectral features of minerals and other components while they are embedded in their natural medium.

Although the visible and infrared spectra of both chips show that the dominant mineralogy is low-Ca pyroxene, the focus here is on identification of the minor constituents. Infrared spectra measured at multiple spots along the surface of chips 92 and 271 show subtle spectroscopic variations due to changes in the low-Ca pyroxene texture and composition and to the presence of secondary minerals. Absorption bands observed near 0.93 and 1.95 mu m are characteristic of low-Ca pyroxene. Strong mid-infrared reststrahlen bands are observed near 9 and 19.5 mu m in all surface spectra, and additional bands near 7, 10.5, 11.4, 17.8, 20.5 and 23 mu m are variable depending on the low-Ca pyroxene texture and the presence of secondary minerals. Selected spectra exhibit carbonate features near 4, 6.4-7.1 and 11.3 mu m. Detailed analysis of these carbonate features indicates the presence of Mg-Fe carbonate, which is consistent with petrographic studies. Many of these spectra with strong carbonate features exhibit a magnetite feature near 17.9 mu m and a shoulder near 20.5 mu m that cannot be uniquely ascribed to one mineral. Spectroscopic identification of the minor carbonate and magnetite minerals in this probable piece of Mars indicates that detection of small amounts of these minerals of possible biological significance will be possible using infrared hyperspectral analyses of the Martian surface. Also of importance for remote sensing on Mars is the result that Mg, Fe and Mg-Fe carbonates in a low-Ca pyroxene matrix should be distinguishable from one another in the spectral region measured by the thermal emmitance spectrometer (TES).

These glass samples, when combined with literature data on a separate single glass inclusion from EET 79001 and a glass vein from Zagami, permit examination in greater detail of the isotopic composition of Ne, Ar, Kr, and Xe trapped from the Martian atmosphere. The isotopic composition of Martian Ne, if actually present in these glasses, remains poorly defined. The (super 40) Ar/ (super 36) Ar ratio of trapped Martian atmospheric Ar is probably considerably lower than the nominal ratio of 3000 measured by Viking, and data on impact glasses suggest a value of approximately 1900. The atmospheric (super 36) Ar/ (super 38) Ar ratio is < or =4.0. Martian atmospheric Kr may be enriched in lighter isotopes by approximately 0.5%/amu compared to both solar-wind Kr and to the Martian composition previously reported. The isotopic composition of Xe in these glasses agrees with that previously reported in the literature. The Martian atmospheric (super 36) Ar/ (super 132) Xe and (super 84) Kr/ (super 132) Xe elemental ratios are higher than those reported by Viking by factors of approximately 2.5-1.6 (depending on the (super 40) Ar/ (super 36) Ar ratio adopted) and approximately 1.8, respectively, and are discussed in a separate paper. Cosmogenic gases indicate space exposure ages of 2.7 + or - 0.6 Ma for QUE 94201 and Shergotty and 14 + or - 1 Ma for ALH 84001. Small amounts of (super 21) Ne produced by energetic solar protons may be present in QUE 94201 but are not present in ALH 84001 or Y-793605. The space exposure age for Y-793605 is 4.9 + or - 0.6 Ma and appears to be distinctly older than the ages for basaltic shergottites. However, uncertainties in cosmogenic production rates still makes somewhat uncertain the number of Martian impact events required to produce the exposure ages of Martian meteorites.

II. Feasibility analysis AN - 17222086; 4507942 AB - The feasibility of observing global tropospheric and total ozone (O sub(3)) fields with a double-etalon Fabry-Perot interferometer (FPI) has been assessed. The FPI provides high spectral resolution and high- throughput capabilities that enable observation in pressure-broadened wings of strong O sub(3) lines while minimizing the impact of undesirable signal contributions (i.e., from the terrestrial surface and interfering species). A retrieval technique has been implemented and is demonstrated for a tropical atmosphere possessing enhanced tropospheric ozone amounts. An error analysis assessing the impact on retrieved O sub(3) amounts from the most significant uncertainties associated with this particular measurement has been performed, and findings for a tropical atmosphere are presented. Results show the proposed instrumentation to enable a good measurement of absolute ozone amounts and an even better determination of relative changes.

I. Instrument concept AN - 17218291; 4507943 AB - The global distribution of tropospheric ozone (O sub(3)) can be observed from a satellite-based instrument by spectrally isolating the pressure-broadened wings of strong O sub(3) lines. The Fabry-Perot interferometer (FPI) provides high spectral resolution and high-throughput capabilities that are essential for performing such a measurement. Through proper selection of channel spectral regions, the FPI optimized for tropospheric O sub(3) measurements can simultaneously observe a stratospheric component and thus the total O sub(3) column abundance. We present a conceptual instrument design that involves a double-etalon fixed-gap series configuration FPI along with an ultranarrow bandpass filter to achieve single-order operation with an overall spectral resolution of approximately 0.068 cm super(-1), sampling the narrow 1054.2-1055.2 cm super(-1) spectral region within the strong 9.6- mu m ozone infrared band from a nadir-viewing satellite configuration.

In order to successfully meet this goal, it is necessary to develop nondestructive inspection techniques which will facilitate the production of the materials used in these aircraft and assure the quality necessary to maintain airworthiness. This paper will discuss a particular class of general aviation materials and several nondestructive inspection techniques that have proven effective for making these inspections. Additionally, this paper will discuss the investigation and application of other commercially available quality control techniques applicable to these structures.

The hazard is mitigated by minimizing or detecting, in the vehicle environment, the three ingredients essential to producing fire: fuel, oxidizer, and an ignition source. The Linear Aerospike SR-71 Experiment (LASRE) consisted of a linear aerospike rocket engine integrated into one-half of an X-33-like lifting body shape, carried on top of an SR-71 aircraft. Gaseous hydrogen and liquid oxygen were used as propellants. Although LASRE is a one-of-a-kind experimental system, it must be rated for piloted flight, so this test presented a unique challenge. To help meet safety requirements, the following propulsion hazard mitigation systems were incorporated into the experiment: pod inert purge, oxygen sensors, a hydrogen leak detection algorithm, hydrogen sensors, fire detection and pod temperature thermocouples, water misting, and control room displays. These systems are described, and their development discussed. Analyses, ground test, and flight test results are presented, as well as findings and lessons learned.

Statistical analysis of the mean-field bias is performed on a 2-year record of WSR-88D observations from Tulsa, Okla., and rain gauge measurements from a dense network under the radar umbrella. The analysis shows strong seasonal effect. A data-based Monte Carlo simulation experiment is performed on the same data to quantify the sampling error of estimated bias for varying rain gauge network densities. Simulation results show (1) that the sampling error decreases proportionally to the square of the rain gauge network density; and (2) that the sampling error is higher in the warm season. The performance of three mean-field radar-rainfall bias estimation and prediction algorithms is investigated. The algorithms include the WSR-88D precipitation adjustment procedure, the adaptive error parameter technique, and the maximum likelihood autoregressive model. A Monte Carlo simulation experiment is used to assess the algorithms' error statistics for the two seasons, three accumulation timescales, and two modes of operation (prediction and update).

In these studies, temporal gaps in the satellite archive are common due to difficulties associated with availability of cloud-free data, costs, temporal discontinuities between satellite sensors, etc. In this probability study, examples of multitemporal image sequences with data gaps are considered in order to illustrate error rates associated with estimating the age of secondary tropical forest. Results indicate that on the order of 8-32% of scene pixels may be misclassified with respect to age if land cover transitions which occur within the data gap(s) are ignored. Using secondary forest regeneration rates from the literature, calculations showed that these gap errors caused the above-ground biomass to be overestimated by 8-23%. The error rates are scene-dependent. The results are presented to flag a potentially significant source of error.

For O sub(3), two UV instruments agree within 7% (95% cl.) limited by a difference in response of 7.0% plus or minus 0.2% (95% cl.) which likely was caused by O sub(3) losses in one of the inlet lines. The NO mixing ratios obtained by two NO/O sub(3) Chemiluminescence (CL) instruments range between 0-200 parts per trillion by volume (pptv), except for short periods influenced by traffic pollution. The response of the two CL detectors agrees within 3% plus or minus 10% (95% cl.). The NO sub(y) data, ranging between 100 pptv and several ppbv in plumes, were obtained using two different gold-CO-converters and inlet designs with subsequent CL detection of NO. A systematic difference in the slope between the two data series of 1.44 plus or minus 0.05 (95% cl.) was likely caused by NO sub(y) losses in the inlet line of one of the instruments. Three different NO sub(2) data sets were obtained using Tunable Diode Laser Absorption Spectroscopy (TDLAS), a photolytic converter/CL technique (PLC/CL), and the Matrix Isolation Electron Spin Resonance (MIESR) technique. The linear slopes between the data sets of the three methods are consistent with unity at a 95% confidence level, 1.13 plus or minus 0.30 (TDL versus PLC/CL), 0.90 plus or minus 0.47 (TDL versus MIESR), and 1.04 plus or minus 0.34 (PLC/CL versus MIESR). RO sub(x) measurements were performed by three different chemical amplifier (CA) designs and the MIESR technique. Using 30-min averaged values between 13-65 pptv, two CA instruments agree within 25% (95% cl.) with the mean of MIESR (1.01 plus or minus 0.20 and 0.98 plus or minus 0.24, 95% cl.), while the third CA responded low (0.65 plus or minus 0.32, 95% cl.).

Measurements of NO, NO sub(2), NO sub(y), PAN, J sub(NO[sub]2), CO, VOC, HCHO, H sub(2)O sub(2), O sub(3), and RO sub(x) were made to study the photochemical processes which control the oxidizing capacity of the remote troposphere. Special attention was paid to the processes controlling the budget of ozone. Diurnal changes in the concentration of the species resulted primarily from the transition between downslope flow (usually free tropospheric air) and upslope flow (a mixture of marine boundary layer air and free tropospheric air modified by island emissions). Median concentrations for downslope and upslope conditions were NO sub(x) (47/76 parts per trillion by volume (pptv)), NO sub(y) (392/519 pptv), peroxyacetylnitrate (PAN) (10/23 pptv), CO (89/92 parts per billion by volume (ppbv), ethane (499/486 pptv), propane (35/40 pptv), ethene (25/31 pptv), isoprene (0/60 pptv), HCHO (1.1/1.4 ppbv), H sub(2)O sub(2) (2.4/2.1 ppbv), and O sub(3) (40/38 ppbv). Maximum amounts of RO sub(x) were measured around noon and reached values up to 70 pptv with no observable signal in the night during downslope conditions. JF - Journal of Geophysical Research. D.

AN - 69264269; 11542404 AB - Flight data obtained between 1995 and 1997 from the Cosmic Radiation Environment Monitors CREAM & CREDO carried on UoSat-3, Space Shuttle, STRV-1a (Space Technology Research Vehicle) and APEX (Advanced Photovoltaic and Electronics Experiment Spacecraft) have been added to the dataset affording coverage since 1990. The modulation of cosmic rays and evolution of the South Atlantic Anomaly are observed, the former comprising a factor three increase at high latitudes and the latter a general increase accompanied by a westward drift. Comparison of particle fluxes and linear energy transfer spectra is made with improved environment & radiation transport calculations which account for shield distributions and secondary particles. While there is an encouraging convergence between predictions and observations, significant improvements are still required, particularly in the treatrnent of locally produced secondary particles.

AN - 69263690; 11536872 AB - Phototropism experiments were done with sporangiophores of the fungus Phycomyces blakesleeanus to characterize the interaction between far-UV, blue and red light. Far-UV light elicits negative phototropism (bending away from the light source) while blue light elicits positive phototropism (bending toward the light source). In contrast, red light above 600 nm is phototropically inert. Phototropism was analyzed with light regimens of bilateral or unilateral irradiation with far-UV and blue light. Under bilateral irradiation, in which the two light sources were facing each other, blue light partially inhibited the far-UV-elicited phototropism. A fluence-response curve for this inhibition showed that blue light was maximally effective at fluence rates which exceeded 3 to 57 times that of the far-UV. Tonic red light, which was given from above, abolished to a large extent the antagonistic action of blue light. With a regimen of unilateral irradiation, i.e. when far-UV and blue light were given from the same side, a phototropic balance could be achieved with approximately equal fluence rates of blue and UV light. Above or below this critical balance point the bending was either negative or positive. In this setup the effect of tonic red light was complex. First, it caused an enhancement of the positive or negative bending, and second, it caused at some fluence rates a sign reversal from positive to negative phototropism. The balance point itself was only marginally affected. The data cannot be explained on the basis of a single photoreceptor and support the previous notion of separate far-UV and blue-light receptors. The antagonism between these two receptors probably occurs on the level of a red-light-absorbing receptor intermediate.

AN - 69259206; 11541819 AB - The MOx instrument was developed to characterize the reactive nature of the martian soil. The objectives of MOx were: (1) to measure the rate of degradation of organics in the martian environment; (2) to determine if the reactions seen by the Viking biology experiments were caused by a soil oxidant and measure the reactivity of the soil and atmosphere: (3) to monitor the degradation, when exposed to the martian environment, of materials of potential use in future missions; and, finally, (4) to develop technologies and approaches that can be part of future soil analysis instrumentation. The basic approach taken in the MOx instrument was to place a variety of materials composed as thin films in contact with the soil and monitor the physical and chemical changes that result. The optical reflectance of the thin films was the primary sensing-mode. Thin films of organic materials, metals, and semiconductors were prepared.

AN - 69257548; 11541422 AB - To investigate the regularity of carbon monoxide outgassing from nonmetallic materials in air tight cabin, two nonmetallic materials was observed. 30-9304 foam plastics and aluminum-plated polyester adhesive film were sealed in airtight glass ampules, and outgassed for 70 days at four different temperatures. The outgassing CO was determined continuously with transform/gas chromatography. Curve fitting and regression were used in data analysis. The results showed that: (1) when temperature was kept constant, the relation between the outgassed CO and outgassing time appeared to be a "s" shaped or exponented curve; (2) at a fixed time the amount of outgassed CO increased with temperature exponentially; (3) the amount of CO outgassed in 12 h at 100 degrees C from the two materials corresponds those for 45 d at 50 degrees C, there is an iso-effect principle for CO outgassing.

It is planned to be left on the space station to study the process that bacteria in MIR space station had acquired their resistance to cosmic ray radiation as well as ultra-violet light. As contrasted with the space experiment, bacteria are cultivating in the ECC on the ground to trace the changes of bacteria under the simulated radiation dose in Earth orbit.

This shift represents temperatures during the bloom season, and may be less than the winter temperature drop. The sharp transition itself, with a duration of about 200 years, suggests that the temperature decrease may have been as large as 12 degrees C. Previous estimates of the Alleroed/Younger Dryas temperature shifts are controversial, and range from 3-20 degrees C, suggesting that further interdisciplinary research on the same samples is warranted.

It is estimated that about three quarters of the world's terrestrial water reserves are locked in snow and ice. The principal objective of this study is to analyze the degree to which passive microwave radiation can be used to interpret snow water equivalent (SWE). The methodology reflects the importance of isolating phenomena other than SWE that may influence the microwave signal. These factors include: snow wetness, depth hoar, complex mountainous terrain, and dense forest cover. Applying these four variables, 16 land-cover categories were identified, and relationships between SWE and brightness temperature were derived for each category. Results show that, for the 'simplest' of these categories, a nonforested, nonmountainous terrain, with no depth hoar or melting snow, the SWE can be estimated with 95% confidence within plus or minus 44 mm. The confidence limits increase as the complexity of the snowpack, land form, and land cover increases.

AN - 1787972396; PQ0002993654 AB - The West Antarctic ice sheet, which contains enough ice to raise sea level by 5 m, has been in the scientific spotlight over much of the last 30 years. Recent concern centers on whether all or part of the ice it contributes to the ocean might be delivered rapidly [IPCC, 1996; Oppenheimer, 1998]. Investigating this potential has led Antarctic scientists to address a series of related questions: Why, when, and how much ice has been lost by the ice sheet since the Last Glacial Maximum? Was the ice sheet ever smaller during Glacial Minima than it is today? And, do the ice sheet's fringing ice shelves or its marine base make it inherently unstable?

Results confirm previous reports that O sub(2) concentrations in the upper water column exceed atmospheric equilibrium and that N sub(2) and Ar are supersaturated throughout the water column. The mean supersaturation of N sub(2) was found to be 2.0 ( plus or minus 0.37) and Ar was 3.8 ( plus or minus 1.1). The ratios of N sub(2)/Ar (20.3 plus or minus 3.8), and O sub(2)/Ar (22.5 plus or minus 4.0) at the ice-water interface are consistent with those previously measured, suggesting that bubble formation is the main process for removing gas from the lake. However, the saturations of N sub(2) and Ar greatly exceed those previously predicted for degassing by bubble formation only at the ice-water interface. The data support the hypothesis that removal of gas by bubbles occurs in the water column to a depth of 11 m in Lake Hoare. CO sub(2) concentration increases from near zero at the ice-water interface to 80-100 times saturation at and below the chemocline at c. 28 m. There is considerable variability in the gas concentrations throughout the water column; samples separated in depth by one metre may vary by more than 50% in gas content. It is likely that this phenomenon results from the lack of turbulent mixing in the water column. Methane (c. 2 [mu]g 1 super([minus sign]1)) was detected below the chemocline and immediately above the sediment/water interface at a depth of 30 m. Samples from lakes Vanda, Joyce, and Miers, also show supersaturations of O sub(2), N sub(2), and Ar at levels similar to levels found in Lake Hoare.

The AIR ER-2 flight measurements will enable scientists to study the radiation risk associated with the high-altitude operation of a commercial supersonic transport. The ER-2 radiation measurement flights will follow predetermined, carefully chosen courses to provide an appropriate database matrix which will enable the evaluation of predictive modeling techniques. Explicit scientific results such as dose rate, dose equivalent rate, magnetic cutoff, neutron flux, and air ionization rate associated with those flights are predicted by using the AIR model. Through these flight experiments, we will further increase our knowledge and understanding of the AIR environment and our ability to assess the risk from the associated hazard.

N1 - Last updated - 2011-12-13 ER - TY - JOUR T1 - The Use of Digital Warping of Microwave Integrated Water Vapor Imagery to Improve Forecasts of Marine Extratropical Cyclones AN - 17091986; 4392934 AB - A technique is described in which forecasts of the locations of features associated with marine cyclones may be improved through the use of microwave integrated water vapor (IWV) imagery and image warping of forecast mesoscale model fields. Here, image warping is used to optimally match mesoscale model output to observations of IWV measured by microwave sensors. In the mesoscale model simulations presented here (one of the March 1993 "superstorm," one of a rapidly deepening cyclone observed in the North Atlantic in February 1992, and one of the ERICA IOP 4 cyclone), the Pennsylvania State University-National Center for Atmospheric Research MM5 model is initialized from the standard National Meteorological Center (recently renamed the National Centers for Environmental Prediction) operational analysis. The simulations are then run until a time at which a Special Sensor Microwave/Imager (SSM/I) overpass occurs. For each simulation, the forecast pattern of IWV is then compared to the field shown in the SSM/I image. In all three cases, the MM5 moves the cyclones too slowly, and therefore places distinguishing features in the forecast IWV fields significantly upstream of their locations as revealed in the microwave imagery.

Because the TRMM Precipitation Radar (PR) footprint size of 4.3 km is greater than the scale of some convective rainfall events, there is concern that nonuniform filling of the PR antenna beam may bias the retrieved rain-rate profile. The authors investigate this effect theoretically and then observationally using data from the NASA Jet Propulsion Laboratory Airborne Rain Mapping Radar (ARMAR), acquired during Tropical Oceans Global Atmosphere Coupled Ocean-Atmosphere Response Experiment in early 1993. The authors' observational approach is to simulate TRMM PR data using the ARMAR data and compare the radar observables and retrieved rain rate from the simulated PR data with those corresponding to the high-resolution radar measurements. The authors find that the path-integrated attenuation and the resulting path-averaged rain rate are underestimated. The reflectivity and rain rate near the top of the rainfall column are overestimated. The near-surface reflectivity can be overestimated or underestimated, with a mean error very close to zero. The near-surface rain rate, however, is usually underestimated, sometimes severely.

The data were obtained from aboard a small jet aircraft flying in near-field (< 20 km aircraft separation) wakes generated by a variety of aircraft. All aircraft produced large numbers of particles relative to background concentrations, a majority of which evaporated at temperatures < 200 degree C. The volatile particles, except under humid conditions, were typically < 20 nm in diameter, and their numbers varied both as a function of atmospheric conditions and plume age. Their apparent number-density dependence upon fuel sulfur content, and the fact that their inferred mass concentrations are less than the reported shortfall in gas phase sulfur budgets, strongly suggests they were primarily composed of condensed sulfur species.

The data were obtained using an instrumented jet aircraft, flown repeatedly through aircraft wakes. These aircraft were observed to produce 0.5 - 10 x 10 super(15) nonvolatile particles kg super(-1) of fuel burned. Their numbers varied as a function of aircraft type, age, and engine operating parameters, but less with atmospheric conditions. Large numbers of volatile aerosols were measured in all cases. Volatile EI's ranged from 0.1 to 40 x 10 super(16) kg super(-1) fuel burned. The observed soot emissions are estimated to have only a minor impact on atmospheric aerosol loading, but a future fleet producing such high concentrations of implied sulfate aerosols could perturb cloud formation and heterogeneous chemical processes in the upper troposphere/lower stratosphere.

The two orders of magnitude size range covered by the measurements correspond to 6-7 orders of magnitude particle concentration. The data determined a nucleation mode, composed of aircraft-emitted sulfuric acid aerosol, that contributed between 62% and 85% to the total aerosol surface area and between 31% and 34% to its volume. Soot aerosol contributed 0.3% to the surface area and 0.07% to the volume of sulfuric acid aerosol.

AN - 69977688; 11540642 AB - The maize Ac-Ds transposable element family has been used as the basis of transposon mutagenesis systems that function in a variety of plants, including Arabidopsis. We have developed modified transposons and methods which simplify the detection, cloning and analysis of insertion mutations. We have identified and are analyzing two plant lines in which genes expressed either in the root cap cells or in the quiescent cells, cortex/endodermal initial cells and columella cells of the root cap have been tagged with a transposon carrying a reporter gene. A gene expressed in root cap cells tagged with an enhancer-trap Ds was isolated and its corresponding EST cDNA was identified. Nucleotide and deduced amino acid sequences of the gene show no significant similarity to other genes in the database. Genetic ablation experiments have been done by fusing a root cap-specific promoter to the diphtheria toxin A-chain gene and introducing the fusion construct into Arabidopsis plants. We find that in addition to eliminating gravitropism, root cap ablation inhibits elongation of roots by lowering root meristematic activities.

The number of last occurrences of taxa reaches a maximum close to the local base of the Tesero horizon of the Werfen Formation. Taxa that have < or =15% stratigraphic abundance (percent of sample intervals in which a taxon occurs) show last occurrences well before that level, whereas taxa with more complete records tend to disappear at or close to that level. These results are in agreement with simulations for abrupt extinctions, as opposed to gradual or steplike extinction scenarios, and support predictions of the Signor-Lipps effect, that errors in the end points of biostratigraphic ranges can produce range truncations and apparent gradual decline preceding a sudden extinction boundary. On the basis of estimated sedimentation rates for the Italian sections, the end-Permian extinctions could have been very sudden (< or =30 k.y.), and the disappearance of most latest Permian foraminifers was most likely coincident with a worldwide ecological stress event, identified by a global negative delta (super 13) C anomaly that occurs in Italy near the base or within the time-transgressive Tesero horizon.

A processing method, previously developed for south polar satellite magnetic data (e.g., Magsat), is applied to north polar data to separate the core and external fields from the lithospheric anomalies. The core field is removed with a least-squares procedure and Fourier correlation coefficient filtering effectively reduces the external field signatures. As demonstrated by improved correlation coefficients and reduced sum-of-squared differences between passes and between dawn and dusk maps, the processing effectively extracts the static geologic signal from the dynamic noise (e.g., external fields). Quantitative comparisons of the resulting lithospheric anomaly map with previous maps suggest that the processing maintains anomaly amplitude while significantly reducing non-lithospheric energy. The map shows a long-wavelength contrast across the Ural mountains, the suture zone between the east European craton (+4 nT) and the west Siberian platform (-4 nT). This contrast might be indicative of significant petrologic differences between these large crustal blocks. If the steepest portion of the magnetic gradient is marking the main Uralian fault, then the fault may extend southward to a latitude coincident with the middle of the Aral sea. The easternmost section of the intraplate Tien Shan is marked by a +3 nT anomaly whereas the remainder of the mountain belt is not associated with a significant anomaly. This pattern agrees with previous interpretations that suggest the eastern Tien Shan is supported by a lithospheric root and the rest of the belt is held up by a positive buoyancy force, i.e., it lacks a root.

The most dominant anomaly pattern features a pair of subtropical temperature maxima straddling the equator in the upper troposphere coupled to a corresponding pair of temperature minima in the lower stratosphere in the form of a dipole. Over the Tropics and subtropics, the water vapor content is increased in regions of large-scale ascent with maximum response in the middle troposphere, whereas substantial drying is found in the descending branches of the Walker and Hadley circulations. While the temperature and moisture patterns in the lower troposphere are thermodynamically linked to the sea surface temperature anomaly pattern, the distribution of temperature and water vapor in the upper troposphere is largely controlled by dynamics and much less by thermodynamics. The troposphere-stratosphere temperature dipole is fundamentally due to the rising of the tropopause associated with hydrostatic expansion and vertical ascent in regions of enhanced deep convection. The rising motion pushes colder upper-tropospheric air into the lower stratosphere where the climatological temperature gradient reverses. No such dipole anomaly exists in the moisture field. Numerical experiments with the GEOS GCM show that while atmospheric dynamics are principally responsible for the generation of the basic structures of the temperature and moisture anomalies observed during ENSO, the interaction between the hydrologic cycle and radiation plays an important role in enhancing and modifying the response. The role of hydrologic cycle-radiation interaction is most important in rendering the atmosphere more unstable both columnwise and locally, through enhanced longwave heating in the middle and lower troposphere and cooling above. The enhanced instability leads to intensified Hadley and Walker circulations, which are accompanied by stronger latent heating and a more vigorous hydrologic cycle. The intensified hydrologic cycle promotes further warming and moistening of the middle and lower troposphere, and cooling and drying in the stratosphere. The radiation-dynamics feedback leads to a new equilibrium climate state in which the increased heat transport by convection into the upper troposphere and stratosphere is balanced by increased radiative cooling, which removes the local excessive heat buildup.

The heat pulse is discretized at eight points along the suborbital trajectory. An aerothermal database is generated from both laminar and turbulent flow calculations. With the aerothermal database and one-dimensional thermal protection system stackups, a number of thermal protection system (TPS) sizings are generated. Three major conclusions from the analysis in this study are as follows: 1) The procedure for performing the TPS mapping works well, 2) for the TPS design, a number of traceability issues exist between the X-33 and the full-scale reusable launch vehicle, and 3) for the X-33 TPS material selection, predictions of transition to turbulence and turbulent heating are critical.

N1 - Last updated - 2011-12-13 ER - TY - JOUR T1 - Effects of climate and atmospheric CO sub(2) partial pressure on the global distribution of C sub(4) grasses: present, past, and future AN - 17110453; 4407589 AB - C sub(4) photosynthetic physiologies exhibit fundamentally different responses to temperature and atmospheric CO sub(2) partial pressures (pCO sub(2)) compared to the evolutionarily more primitive C sub(3) type. All else being equal, C sub(4) plants tend to be favored over C sub(3) plants in warm humid climates and, conversely, C sub(3) plants tend to be favored over C sub(4) plants in cool climates. Empirical observations supported by a photosynthesis model predict the existence of a climatological crossover temperature above which C sub(4) species have a carbon gain advantage and below which C sub(3) species are favored. Model calculations and analysis of current plant distribution suggest that this pCO sub(2)-dependent crossover temperature is approximated by a mean temperature of 22 degree C for the warmest month at the current pCO sub(2) (35 Pa). In addition to favorable temperatures, C sub(4) plants require sufficient precipitation during the warm growing season. C sub(4) plants which are predominantly graminoids of short stature can be competitively excluded by trees (nearly all C sub(3) plants) - regardless of the photosynthetic superiority of the C sub(4) pathway - in regions otherwise favorable for C sub(4). To construct global maps of the distribution of C sub(4) grasses for current, past and future climate scenarios, we make use of climatological data sets which provide estimates of the mean monthly temperature to classify the globe into areas which should favor C sub(4) photosynthesis during at least 1 month of the year. This area is further screened by excluding areas where precipitation is <25 mm per month during the warm season and by selecting areas classified as grasslands (i.e., excluding areas dominated by woody vegetation) according to a global vegetation map. Using this approach, grasslands of the world are designated as C sub(3), C sub(4), and mixed under current climate and pCO sub(2). Published floristic studies were used to test the accuracy of these predictions in many regions of the world, and agreement with observations was generally good. We then make use of this protocol to examine changes in the global abundance of C sub(4) grasses in the past and the future using plausible estimates for the climate and pCO sub(2). When pCO sub(2) is lowered to pre-industrial levels, C sub(4) grasses expanded their range into large areas now classified as C sub(3) grasslands, especially in North America and Eurasia. During the last glacial maximum ( similar to 18 ka BP) when the climate was cooler and pCO sub(2) was about 20 Pa, our analysis predicts substantial expansion of C sub(4) vegetation - particularly in Asia, despite cooler temperatures. Continued use of fossil fuels is expected to result in double the current pCO sub(2) by sometime in the next century, with some associated climate warming. Our analysis predicts a substantial reduction in the area of C sub(4) grasses under these conditions. These reductions from the past and into the future are based on greater stimulation of C sub(3) photosynthetic efficiency by higher pCO sub(2) than inhibition by higher temperatures. The predictions are testable through large-scale controlled growth studies and analysis of stable isotopes and other data from regions where large changes are predicted to have occurred.

The authors explore the question of whether these two separate pieces of information might contain insight into climate processes during a perturbation in the climate system. In particular, the relative fluctuations of rain and ice signals could be related to precipitation efficiency, an important determinant of the equilibrium climate, and thus a potential feedback mechanism in climate change. As an example of this potential application, SSM/I-derived liquid and frozen precipitation signals are used to infer changes in tropical oceanic precipitation characteristics during the cool period following the 1991 eruption of Mount Pinatubo. The need for an assessment of the temperature sensitivity of precipitation-retrieval algorithms is also discussed.

This LHR cycle occurred during the hurricane's rapid intensification and decay stages (3-5 October 1995). The satellite observations revealed that there were at least two major episodes in which a period of elevated total LHR (i.e., convective burst) occurred in the eyewall region. During these convective bursts, Opal's minimum pressure decreased by 50 mb and the LHR generated by convective processes increased, as greater amounts of latent heating occurred at middle and upper levels. It is hypothesized that the abundant release of latent heat in Opal's middle- and upper-tropospheric region during these convective burst episodes allowed Opal's eyewall to become more buoyant, enhanced the generation of kinetic energy and, thereby, rapidly intensified the system. The observations also suggest that Opal's intensity became more responsive to the convective burst episodes (i.e., shorter time lag between LHR and intensity and greater maximum wind increase) as Opal became more intense. Analyses of SSM/I-retrieved parameters, sea surface temperature observations, and the European Centre for Medium-Range Weather Forecasts (ECMWF) data reveal that the convective rainband (CRB) cycles and sea surface and tropopause temperatures, in addition to large-scale environmental forcing, had a profound influence on Opal's episodes of convective burst and its subsequent intensity. High sea surface (29.7 degree C) and low tropopause (192 K) temperatures apparently created a greater potential for Opal's maximum intensity. Strong horizontal moisture flux convergence within Opal's outer-core regions (i.e., outside 333-km radius from the center) appeared to help initiate and maintain Opal's CRBs. These CRBs, in turn, propagated inward to help generate and dissipate the eyewall convective bursts. The first CRB that propagated into Opal's eyewall region appeared to initiate the first eyewall convective burst. The second CRB propagated to within 111 km of Opal's center and appeared to dissipate the first CRB, subjecting it to subsidence and the loss of water vapor flux. The ECMWF upper-tropospheric height and wind analyses suggest that Opal interacted with a diffluent trough that initiated an outflow channel, and generated high values of upper-tropospheric eddy relative angular momentum flux convergence. The gradient wind adjustment processes associated with Opal's outflow channel, in turn, may have helped to initiate and maintain the eyewall convective bursts. The ECMWF analyses also suggest that a dry air intrusion within the southwestern quadrant of Opal's outer-core region, together with strong vertical wind shear, subsequently terminated Opal's CRB cycle and caused Opal to weaken prior to landfall.

Materials and methods: Human lymphocytes were exposed to 2 Gy and 5 Gy of gamma -rays. Chromosome aberrations were studied using the fluorescence in situ hybridization (FISH) technique with whole chromosome-specific probes, together with human telomere probes. Chromosomes 2 and 4 were chosen in the present study. Results: The percentage of incomplete exchanges was 27% when telomere signals were not considered. After excluding false incomplete exchanges identified by the telomere signals, the percentage of incomplete exchanges decreased to 11%. Since telomere signals appear on about 82% of the telomeres, the percentage of true incomplete exchanges should be even lower and was estimated to be 3%. This percentage was similar for chromosomes 2 and 4 and for doses of both 2 Gy and 5 Gy. Conclusions: The percentage of true incomplete exchanges is significantly lower in gamma -irradiated human lymphocytes than the frequencies reported in the literature.

N1 - Last updated - 2015-03-24 ER - TY - JOUR T1 - A common-sense climate index: Is climate changing noticeably? AN - 16347218; 4273532 AB - We propose an index of climate change based on practical climate indicators such as heating degree days and the frequency of intense precipitation. We find that in most regions the index is positive, the sense predicted to accompany global warming. In a few regions, especially in Asia and western North America, the index indicates that climate change should be apparent already, but in most places climate trends are too small to stand out above year-to- year variability. The climate index is strongly correlated with global surface temperature, which has increased as rapidly as projected by climate models in the 1980s. We argue that the global area with obvious climate change will increase notably in the next few years. But we show that the growth rate of greenhouse gas climate forcing has declined in recent years, and thus there is an opportunity to keep climate change in the 21st century less than 'business-as-usual' scenarios.

Greenhouse gases warm the Earth's surface but cool the stratosphere radiatively and therefore affect ozone depletion. Here we investigate the interplay between projected future emissions of greenhouse gases and levels of ozone-depleting halogen species using a global climate model that incorporates simplified ozone-depletion chemistry. Temperature and wind changes induced by the increasing greenhouse-gas concentrations alter planetary-wave propagation in our model, reducing the frequency of sudden stratospheric warmings in the Northern Hemisphere. This results in a more stable Arctic polar vortex, with significantly colder temperatures in the lower stratosphere and concomitantly increased ozone depletion. Increased concentrations of greenhouse gases might therefore be at least partly responsible for the very large Arctic ozone losses observed in recent winters. Arctic losses reach a maximum in the decade 2010 to 2019 in our model, roughly a decade after the maximum in stratospheric chlorine abundance. The mean losses are about the same as those over the Antarctic during the early 1990s, with geographically localized losses of up to two-thirds of the Arctic ozone column in the worst years. The severity and the duration of the Antarctic ozone hole are also predicted to increase because of greenhouse-gas-induced stratospheric cooling over the coming decades.

AN - 79629666; 11543363 AB - Recent advances in room-temperature, near-IR and visible diode laser sources for tele-communication, high-speed computer networks, and optical data storage applications are enabling a new generation of gas-dynamic and combustion-flow sensors based on laser absorption spectroscopy. In addition to conventional species concentration and density measurements, spectroscopic techniques for temperature, velocity, pressure and mass flux have been demonstrated in laboratory, industrial and technical flows. Combined with fibreoptic distribution networks and ultrasensitive detection strategies, compact and portable sensors are now appearing for a variety of applications. In many cases, the superior spectroscopic quality of the new laser sources compared with earlier cryogenic, mid-IR devices is allowing increased sensitivity of trace species measurements, high-precision spectroscopy of major gas constituents, and stable, autonomous measurement systems. The purpose of this article is to review recent progress in this field and suggest likely directions for future research and development. The various laser-source technologies are briefly reviewed as they relate to sensor applications. Basic theory for laser absorption measurements of gas-dynamic properties is reviewed and special detection strategies for the weak near-IR and visible absorption spectra are described. Typical sensor configurations are described and compared for various application scenarios, ranging from laboratory research to automated field and airborne packages. Recent applications of gas-dynamic sensors for air flows and fluxes of trace atmospheric species are presented. Applications of gas-dynamic and combustion sensors to research and development of high-speed flows aeropropulsion engines, and combustion emissions monitoring are presented in detail, along with emerging flow control systems based on these new sensors. Finally, technology in nonlinear frequency conversion, UV laser materials, room-temperature mid-IR materials and broadly tunable multisection devices is reviewed to suggest new sensor possibilities.

A low-T silicate cooling rate based on slopes of (super 40) Ar/ (super 39) Ar release profiles, is calculated. One pyroxene and three plagioclase separates were analysed from two different clasts of Vaca Nuerta, and from one clast of Mount Padbury, mesosiderites. The average (super 40) Ar- (super 39) Ar age is found to be 3940 + or - 100 m.y. (range 3770 to 4130 m.y.). Sloped age plateaux indicate Ar closure over > 500 m.y. and relatively slow cooling rates at < approximately 400 degrees C.

Very long baseline interferometry (VLBI) will continue to be a principal technique. However, it will have greatly improved precision and temporal resolution, making possible more in-depth studies of geophysical phenomena affecting Earth rotation. Originally developed as a radio astronomical technique for high-resolution mapping of distant radio sources, VLBI, when "turned around," has become a valuable tool in geodesy. Because of its past success, a new VLBI project, Continuous Observation of the Rotation of the Earth (CORE), was launched last year. It is being implemented in phases by the NASA Goddard Space Flight Center in collaboration with the U.S. Naval Observatory (USNO) [see Ma et al., 1997].

Due to the ambient acceleration levels anticipated for the International Space Station, active vibration isolation is required to provide a quiescent acceleration environment for many science experiments. An overview is given of systems developed and flight tested in orbit for microgravity vibration isolation. Technology developed for vibration control of flexible space structures may also be applied to control of terrestrial structures such as buildings and bridges subject to wind loading or earthquake excitation. Recent developments in modern robust control for flexible space structures are shown to provide good structural vibration control while maintaining robustness to model uncertainties. Results of a mixed H-2/H-infinity control design are provided for a benchmark problem in structural control for earthquake resistant buildings.

Palaeoclimatologists have used this relationship to infer palaeotemperatures from the isotope palaeodata extractable from ice cores, deep groundwaters and other such sources. For this application to be valid, however, the relationship, which is derived from spatially distributed present day data, must also hold over time at a given location as it experiences climatic changes. In the paper the authors review recent progress in water isotope modelling aimed at examining and evaluating this assumption. They focus on the use of simple Rayleigh type distillation models and of general circulation models fitted with isotope tracer diagnostics. These models are particularly well suited for examining how such factors as local temperature, evaporative source temperature and precipitation seasonality affect an isotope signal over time.

This ratio is governed by fractionation during evaporation and sea-ice formation and by the isotopic content of precipitation and runoff entering the oceans. The delta (super 18) O (sub omega ) at any point depends on a balance between local evaporation, precipitation, and regional ocean and sea-ice processes. Surface delta (super 18) O (sub omega ) equilibrates after 30-50 model years to produce a pattern of high values (0.5-1.5 per mil ) in the sub-tropics (highest in the Indian and Atlantic oceans) and low values (-15--1 per mil ) in the mid-to-high latitudes. Arctic values are low especially where runoff enters from Arctic rivers. Comparisons with data show that regional linear relationships between delta (super 18) O (sub w ) and salinity are reasonably captured by the model. Surface data from the entire ocean show a clear distinction in slope between the tropical oceans and the extra-tropics, however, departures from the linear relationships are significant. Importantly for attempts at calculating paleo-salinities, the seasonal and longer-term temporal gradients (Delta delta (super 18) O (sub w ) /Delta S at a fixed point) are not generally equal to the spatial gradient (at a fixed time).

Fortunately, Mars is also a planet with abundant natural resources, including assessible materials that can be used to support human life and to sustain a self-sufficient martian outpost. Resources required include water, breathable air, food, shelter, energy, and fuel. Through a mission design based on in situ resource development, we can establish a permanent outpost on Mars beginning with the first manned mission. This paper examines the potential for supporting the first manned mission with the objective of achieving self-sufficiency through well-understood resource development and a program of rigorous scientific research aimed at extending that capability. We examine the potential for initially extracting critical resources from the martian environment, and discuss the scientific investigations required to identify additional resources in the atmosphere, on the surface, and within the subsurface. We also discuss our current state of knowledge of Mars, technical considerations of resource utilization, and using unmanned missions' data for selecting an optimal site. The primary goal of achieving self- sufficiency on Mars would accelerate the development of human colonization beyond Earth, while providing a robust and permanent martian base from which humans can explore and conduct long-term research on planetary evolution, the solar system, and life itself.

Merr. cv. McCall) for use in bioregenerative life support systems. Stand CO2 exchange rates were determined from nocturnal increases in CO2 (respiration) and morning drawdowns (net photosynthesis) to a set point of 1000 micromol/ mol each day (i.e., a closed system approach). Atmospheric samples were analyzed throughout growth for ethylene using gas chromatography with photoionization detection (GC/PH). Water use was monitored by condensate production from the humidity control system, as well as water uptake from the nutrient solution reservoirs each day. Nutrient uptake data were determined from daily additions of stock solution and acid to maintain an EC of 0.12 S/m and pH of 5.8. Dry mass yields of seeds, pods (without seeds), leaves, stems, and roots are provided, as well as elemental and proximate nutritional compositions of the tissues. A methods section is included to qualify any assumptions that might be required for the use of the data in plant growth models, along with a daily event calendar documenting set point adjustments and the occasional equipment or sensor failure.

N1 - Last updated - 2011-12-13 ER - TY - JOUR T1 - Beamfilling errors in passive microwave rainfall retrievals AN - 16434059; 4335276 AB - There are currently large numbers of rainfall retrieval algorithms based upon passive microwave radiances. Most of these algorithms are physically based in that they use explicit physical assumptions to derive relationships between brightness temperatures (Tb's) and rainfall. If these assumptions involve observable quantities, then the physical basis of the algorithms can be extended to determine fundamental uncertainties in the retrieved precipitation fields. In this paper this process begins by examining the largest uncertainty in many of the physical models - the homogeneous rainfall assumption. Four months of Tropical Oceans Global Atmosphere Coupled Ocean-Atmosphere Response Experiment shipborne radar data is used to describe the horizontal characteristics of rain. The vertical hydrometeor structures needed to simulate the upwelling Tb are taken from a dynamical cloud model. Radiative transfer computations were performed using a fully three-dimensional Monte Carlo solution in order to test all aspects of the beamfilling problem. Results show that biases as well as random errors depend upon the assumed vertical structure of hydrometeors, the manner in which inhomogeneity is modeled in the retrieval, and the manner in which the radiative transfer problem is handled. Unlike previous works, the goal of this paper is not to determine a mean beamfilling correction or a vertical hydrometeor profile that should be applied to specific retrieval algorithms. Rather, it is to explore the impact of inhomogeneous rainfall upon the predicted brightness temperatures so that these relations may eventually be used to develop a physically based error model for microwave precipitation retrievals. Because the predicted Tb's depend upon assumed cloud vertical structures, the paper offers a procedure to account for the uncertainty introduced by rainfall inhomogeneity rather than a general result. The impact of inhomogeneous rainfall upon specific algorithms must still be investigated within the context of that specific algorithm.

The objective of the software metrics program is to assess risk areas at each phase of the development life cycle and project them into the future. The software development goals in the metrics program are evaluated by a set of attributes that help to define and classify risks. The attributes must be "measurable" by a set of metrics. These metrics must be based on data that is collectable within the confines of the software development process and must also be relevant to the quality attributes and risk assessment. This paper discusses the SATC's software risk assessment metrics program which meets these needs and is currently being applied to software developed for NASA. At each phase of the software development life cycle, attributes will be identified and metrics defined. Project data is used to demonstrate how the metric analysis was applied at that phase for risk assessment, and how that information could be used by management to manage project risks.

AN - 21069933; 11287793 AB - A times series framework (TSF) tool was utilized to view time series data for marine turtles as related to conservation efforts at Kennedy Space Center (KSC) and the Merritt Island National Wildlife Refuge (MINWR). Recently, 109,587 records were entered into an Oracle database. Parameters measured for species Caretta caretta and Chelonia mydas included: nests, false crawls above and below the high tide, number of nest depredated, and disturbed. Future initiatives will include adding marine turtle netting data collected from the lagoonal waters and beach temperature profiles of KSC. Data are queried and viewed using the TSF browser which may run in a UNIX or Windows environment without prior knowledge of standard query language (SQL) or Oracle's procedural language (PL). The TSF browser includes the Browser tool, controlling all the navigation in the database, the Manager Tool controlling data analysis, the Inspector Tool presenting time series characteristics, the Display Tool creating tabular presentations of data, a Plotter Tool, the Slide Show Tool associating images with themes and sites, and the Slide Tool presenting selected images. The TSF browser allows the user to search the desired datasets within the database and select data based on location or parameter. Furthermore, TSF allows for a GIS interface between Arc View and the database. The user selects the datasets to query and a graphical display of those selected sites is presented in the GIS by accessing information within the database.

AN - 85418844; pmid-9525486 AB - Two different space life sciences missions (SLS-1 and SLS-2) have demonstrated that the synapses of the hair cells of rat vestibular maculae increase significantly in microgravity. The results also indicate that macular synapses are sensitive to stress. These findings argue that vestibular maculae exhibit neuroplasticity to macroenvironmental and microenvironmental changes. This capability should be clinically relevant to rehabilitative training and/or pharmacological treatments for vestibular disease. The results of this ultrastructural research also demonstrated that type I and type II hair cells are integrated into the same neuronal circuitry. The findings were the basis for development of three-dimensional reconstruction software to learn details of macular wiring. This software, produced for scientific research, has now been adapted to reconstruct the face and skull directly from computerized tomography scans. In collaboration with craniofacial reconstructive surgeons at Stanford University Medical Center, an effort is under way to produce a virtual environment workbench for complex craniofacial surgery. When completed, the workbench will help surgeons train for and simulate surgery. The methods are patient specific. This research illustrates the value of basic research in leading to unanticipated medical applications.

AN - 85418715; pmid-9525490 AB - Human balance control is known to be transiently disrupted after spaceflight; however, the mechanisms responsible for postflight postural ataxia are still under investigation. In this report, we propose a conceptual model of vestibulospinal adaptation based on theoretical adaptive control concepts and supported by the results from a comprehensive study of balance control recovery after spaceflight. The conceptual model predicts that immediately after spaceflight the balance control system of a returning astronaut does not expect to receive gravity-induced afferent inputs and that descending vestibulospinal control of balance is disrupted until the central nervous system is able to cope with the newly available vestibular otolith information. Predictions of the model are tested using data from a study of the neurosensory control of balance in astronauts immediately after landing. In that study, the mechanisms of sensorimotor balance control were assessed under normal, reduced, and/or altered (sway-referenced) visual and somatosensory input conditions. We conclude that the adaptive control model accurately describes the neurobehavioral responses to spaceflight and that similar models of altered sensory, motor, or environmental constraints are needed clinically to predict responses that patients with sensorimotor pathologies may have to various visual-vestibular or changing stimulus environments.

AN - 79723105; 9496883 AB - A matched set of five tissue-equivalent proportional counters (TEPCs), embedded at the centers of 0 (bare), 3, 5, 8 and 12-inch-diameter polyethylene spheres, were flown on the Shuttle flight STS-81 (inclination 51.65 degrees, altitude approximately 400 km). The data obtained were separated into contributions from trapped protons and galactic cosmic radiation (GCR). From the measured linear energy transfer (LET) spectra, the absorbed dose and dose-equivalent rates were calculated. The results were compared to calculations made with the radiation transport model HZETRN/NUCFRG2, using the GCR free-space spectra, orbit-averaged geomagnetic transmission function and Shuttle shielding distributions. The comparison shows that the model fits the dose rates to a root mean square (rms) error of 5%, and dose-equivalent rates to an rms error of 10%. Fairly good agreement between the LET spectra was found; however, differences are seen at both low and high LET. These differences can be understood as due to the combined effects of chord-length variation and detector response function. These results rule out a number of radiation transport/nuclear fragmentation models. Similar comparisons of trapped-proton dose rates were made between calculations made with the proton transport model BRYNTRN using the AP-8 MIN trapped-proton model and Shuttle shielding distributions. The predictions of absorbed dose and dose-equivalent rates are fairly good. However, the prediction of the LET spectra below approximately 30 keV/microm shows the need to improve the AP-8 model. These results have strong implications for shielding requirements for an interplanetary manned mission.

AN - 69976628; 11541112 AB - The role of ethylene in the development of constant-light injury of potato (Solanum tuberosum L.) and tomato (Lycopersicon esculentum Mill.) was investigated. In one study, silver thiosulfate (STS) was applied to the foliage of four potato cultivars growing under constant light. Leaf area and shoot dry mass of 'Kennebec' and 'Superior', cultivars normally injured by constant light, were greater (P < 0.05) than those of control plants given foliar applications of distilled water. Examination of STS-treated 'Kennebec' leaflets revealed significantly less injury (necrotic spotting and reduced starch content) than the water-treated controls. 'Norland' and 'Denali', cultivars tolerant of constant light, exhibited no differences in growth between treatments. In a second study, injury (necrotic spotting and reduced starch content) was induced in leaflets of 'Denali' when exposed to spray applications of 0.5 mmol L-1 ethephon or air containing 0.5 to 0.8 microL L-1 ethylene. In a third study, three genotypes of 'Ailsa Craig' tomato were grown under constant light. Leaves of the normal 'Ailsa Craig' exhibited epinasty, reduced chlorophyll concentration, and reduced starch content. Leaves of a mutant 'Ailsa Craig', containing the Never ripe mutation, did not exhibit epinasty but exhibited the same amount of reduced chlorophyll concentration and starch content as normal plants. Leaves of a transgenic 'Ailsa Craig', containing an antisense gene of 1-aminocyclopropane 1-carboxylate (ACC) oxidase, were epinastic, but chlorophyll concentration and starch content were greater than in leaves of normal and mutant plants. These results suggest that transgenic plants were more tolerant of constant light than the other genotypes. Evidence from these studies indicates that ethylene, combined with constant light, has an important role in the development of constant-light injury.

AN - 69257405; 11541824 AB - The paper summarized issues, current status and the recent topics in biological research of space radiation. Researches to estimate a risk associated with space radiation exposure during a long-term manned space flight, such as in the International Space Station, is emphasized because of the large uncertainty of biological effects and a complexity of the radiation environment in space. The Issues addressed are; 1) biological effects and end points in low dose radiation, 2) biological effects under low dose rate and long-term radiation exposure, 3) modification of biological responses to radiation under space environments, 4) various aspects of biological end points vs. cellular and molecular mechanisms, 5) estimation of human risk associated with radiation exposure in space flight, 6) regulations for radiation exposure limits for space workers. The paper also summarized and introduced recent progress in space related radiation researches with various biological systems.

It also contains impact melt. Complex zoning patterns in QUE 94201 pyroxenes revealed by elemental map analyses using an electron microprobe suggest a crystallization sequence from Mg-rich pigeonite to extremely Fe-rich pigeonite via {110} Mg-rich augite bands in a single crystal. These textures along with the abundant (maskelynite) indicate single-stage rapid cooling of this rock from a supercooled magma. Transition from Mg-rich augite to Fe-rich pigeonite reflects the onset of plagioclase crystallization. Enrichment of late-stage phases in QUE 94201 implies crystallization from an evolved magma and suggests a different parent magma composition from the other basaltic shergottites. Lithology B of EETA79001 basaltic shergottite contains pyroxenes that show complex zoning with augite bands similar to those in QUE 94201 pyroxene, which suggests similar one-stage rapid cooling. All these basaltic rocks with complex pyroxene zoning suggest rapid metastable crystallization from supercooled magmas. (Auth. mod.)

The corresponding mean annual temperatures are -24.9 degrees C and -23.3 degrees C. These results imply that there is a net flux of water vapour from the ice to the atmosphere resulting in a recession of the ice-cemented ground by about 0.4-0.6 mm yr (sub -1) . The level of the ice-cemented permafrost is about 12 cm below the level of dry permafrost. The summer air temperatures would have to increase about 7 degrees C for thawing temperatures to just reach the top of the subsurface ice. Either subsurface ice at this location is evaporating over time or there are sporadic processes that recharge the ice and maintain equilibrium over long timescales.

We investigated mineralogical constraint on the eucrite metamorphism, especially from opaque mineralogy. Three eucrites with distinct degrees of metamorphism were studied: Y-75011.84 is the least equilibrated basaltic clast, Juvinas shows complex histories of shock and thermal metamorphism, and A-881388 is an extensively annealed and unbrecciated. Three eucrites with different metamorphic histories show distinct opaque mineralogy. In Y-75011.84, ilmenite and troilite are found crystallized in the mesostasis and opaque precipitates within pyroxenes are barely recognized. Juvinas has complicated texture, consisting of a variety of lithologies: Minute precipitates within pyroxene grains in coarse crystalline portions, larger opaque grains in granoblastic pyroxene area and recrystallized mesostases. In A-881388, during extensive prolonged annealing episode, opaque phases, such as ilmenite, troilite, and chromite are almost completely separated from silicate phases and segregated, resulting in a formation of opaque nodules. Several geothermometers, experimental results and the textural appearance of A-881388 suggest that it might have slowly cooled from near 1000-1050 degrees C to nearly equal 800 degrees C during a prolonged annealing episode. While chromite is not observed in Y-75011.84. Juvinas and A-881388 contain chromite in recrystallized mesostases and in an nodule respectively. This implies that chromite could be a metamorphic product.

The buoy is meant to work in shallow aquatic systems (ponds, rivers, lagoons, and semi-enclosed water areas) where strong wind wave action is not a major environmental concern. During the three year project period, a demonstration of the buoy was conducted. The buoy was shown to be totally operational with no tethered communications line. The buoy was made solar powered by large gel cell batteries. The system requires maintenance and continuous operational attention due to the limited lifetimes of various components, in particular the onboard computer. The buoy's purpose was to collected hyperspectral optical signatures for analysis and estimation of water quality parameters such as chlorophyll-a, seston and dissolved organic matter (DOC). The ultimate goal of the project was to develop a buoy that would integrate a probe to measure upwelling light from a source and thus relate this backscattered light to water quality parameters.

The sensors were attached to a boom assembly which could be rotated into the prevailing winds. The boom assembly was mounted on a movable sled which, when extended, allowed sensors to be up to 2 m away from the scaffolding structure to minimize flow distortion. An electronic level with linear actuators allowed the sensors to be remotely levelled once the sled was extended. Two instrument arrays were installed. A primary (fast- response) array consisted of a three-dimensional sonic anemometer, a methane sensor (tunable diode laser spectrometer), a carbon dioxide/water vapor sensor, a fine wire thermocouple and a backup one- dimensional sonic anemometer. The secondary array consisted of a one-dimensional sonic anemometer, a fine wire thermocouple and a Krypton hygrometer. Slow-response sensors provided supporting measurements including mean air temperature and humidity, mean horizontal windspeed and direction, incoming and reflected solar radiation, net radiation, incoming and reflected photosynthetically active radiation (PAR), soil heat flux, peat temperature, water-table elevation and precipitation. A data acquisition system (consisting of an IBM compatible microcomputer, amplifiers and a 16 bit analog-to-digital converter), housed in a small trailer, was used to record the fast response signals. These signals were low-pass filtered (using 8-pole Butterworth active filters with a 12.5 Hz cutoff frequency) and sampled at 25 Hz. Slow-response signals were sampled every 5 s using a network of CR21X data loggers installed in the fen. All signals were averaged over 30-minute periods (runs).

N1 - Last updated - 2014-05-06 ER - TY - RPRT T1 - Sea Ice on the Southern Ocean AN - 17651512; 4464497 AB - Year-round satellite records of sea ice distribution now extend over more than two decades, providing a valuable tool to investigate related characteristics and circulations in the Southern Ocean. We have studied a variety of features indicative of oceanic and atmospheric interactions with Antarctic sea ice. In the Amundsen & Bellingshausen Seas, sea ice extent was found to have decreased by approximately 20% from 1973 through the early 1990's. This change coincided with and probably contributed to recently warmer surface conditions on the west side of the Antarctic Peninsula, where air temperatures have increased by approximately 0.5 C/decade since the mid-1940's. The sea ice decline included multiyear cycles of several years in length superimposed on high interannual variability. The retreat was strongest in summer, and would have lowered the regional mean ice thickness, with attendant impacts upon vertical heat flux and the formation of snow ice and brine. The cause of the regional warming and loss of sea ice is believed to be linked to large-scale circulation changes in the atmosphere and ocean. At the eastern end of the Weddell Gyre, the Cosmonaut Polyna revealed greater activity since 1986, a recurrence pattern during recent winters and two possible modes of formation. Persistence in polynya location was noted off Cape Ann, where the coastal current can interact more strongly with the Antarctic Circumpolar Current. As a result of vorticity conservation, locally enhanced upwelling brings warmer deep water into the mixed layer, causing divergence and melting. In the Ross Sea, ice extent fluctuates over periods of several years, with summer minima and winter maxima roughly in phase. This leads to large interannual cycles of sea ice range, which correlate positively with meridinal winds, regional air temperatures and subsequent shelf water salinities. Deep shelf waters display considerable interannual variability, but have freshened by approximately 0.03/decade since the late 1950's. That could have slowed the thermohaline circulation beneath the Ross Ice Shelf and the properties or volume of local bottom water production.

A total of eight different ozone lines have been observed with frequencies in the range 142-359 GHz. Several back-end spectrometers were able to analyze the incoming signal with very different frequency resolutions and total spectral coverage. This has allowed us to retrieve information about the vertical profile of ozone over a relatively wide range of altitudes. The retrieval itself has been achieved by means of a nonlinear least squares fit of the observed line profile, taking into account the spectroscopic, observational, and instrumental parameters of the different observations. A comparison between the ozone amounts retrieved from observations of different ozone lines in winter and summertime is given separately. Ozone amounts obtained from the different instruments and ozone lines are consistent. JF - Journal of Geophysical Research. D.

A regional geographical information system (GIS) serves as the data source of climate drivers, satellite images, land cover, and soil properties for input to the NASA Ames-CASA (Carnegie-Ames-Stanford Approach) model over a 8-km grid resolution. Simulation results lead us to hypothesize that net primary production (NPP) is limited by cloud interception of solar radiation over the humid north-western portion of the region. Peak annual rates for NPP of nearly 1.4 kg C m super(-2) year super(-1) are localized in the seasonally dry eastern Amazon in areas that we assume are primarily deep-rooted evergreen forest cover. Regional effects of forest conversion on NPP and soil carbon content are indicated in the model results, especially in seasonally dry areas. Comparison of model flux predictions along selected eco-climatic transects reveal moisture, soil, and land use controls on gradients of ecosystem production and soil trace gas emissions (CO sub(2), N sub(2)O, and NO). These results are used to formulate a series of research hypotheses for testing in the next phase of regional modelling, which includes recalibration of the light-use efficiency term in NASA-CASA using field measurements of NPP, and refinements of vegetation index and soil property (texture and potential rooting depth) maps for the region.

Model description and comparison with observations AN - 16360588; 4315247 AB - A biophysical process-based model is used to estimate transpiration, soil evaporation and interception over the global land surface for a 24-month period (January 1987 to December 1988). The model parameters are determined from published records, and their geographical distribution has been prescribed according to land use and land cover data. Satellite observations are used to obtain fractional vegetation cover, isothermal net and photosynthetically active radiation, air temperature and vapor pressure deficit. Precipitation and friction velocity are derived as blended products (disaggregated and assimilated data). The calculated seasonal and geographical variations of evaporation, net radiation and soil moisture are in good agreement with field observations, catchment water balance data, and atmospheric water budget analysis; explained variances being greater than 75%. Uncertainties in the estimated evaporation are about 15 and 20%, respectively, for annual and monthly values.

AN - 79635767; 11542816 AB - Calculations are carried out using density functional theory (DFT) to determine the harmonic frequencies and intensities of 1-methylanthracene, 9-methylanthracene, 9-cyanoanthracene, 2-aminoanthracene, acridine, and their positive ions. The theoretical data are compared with matrix-isolation spectra for these species also reported in this work. The theoretical and experimental frequencies and relative intensities for the neutral species are in generally good agreement, whereas the positive ion spectra are only in qualitative agreement. Relative to anthracene, we find that substitution of a methyl or CN for a hydrogen does not significantly affect the spectrum other than to add the characteristic methyl C-H and C triple bond N stretches near 2900 and 2200 cm-1, respectively. However, addition of NH2 dramatically affects the spectrum of the neutral. Not only are the NH2 modes themselves strong, but this electron-withdrawing group induces sufficient partial charge on the ring to give the neutral molecule spectra characteristics of the anthracene cation. The sum of the absolute intensities is about four times larger for 2-aminoanthracene than those for 9-cyanoanthracene. Substituting nitrogen in the ring at the nine position (acridine) does not greatly alter the spectrum compared with anthracene. JF - The journal of physical chemistry.

Air masses within the anticyclones at altitudes near 850 K ( similar to 32 km) contain similar to 25% less ozone than the surrounding air. Trajectory calculations have revealed that much of the air within the pockets originates in the tropics or subtropics at higher altitudes several weeks earlier. Previous studies have, however, left unanswered a number of questions related to the formation of the low-ozone regions. Using a Lagrangian chemical model with initialization based upon observations from the Upper Atmosphere Research Satellite (UARS), we examine in detail an event in March 1993. Our results demonstrate that the development of the observed ozone pockets can be explained with our current understanding of chemistry and dynamics. The primary mechanism responsible for the development of these low-ozone regions is the isolation of air at high latitudes for periods of time long enough that significant ozone loss toward the local photochemical equilibrium can occur. Such behavior is different from that of the surrounding air masses that move from middle to high latitudes and back again over the course of a few days. The dynamical behavior associated with these latter air masses results in ozone concentrations more consistent with lower-latitude equilibrium values. JF - Journal of Geophysical Research. D.

AN - 79708474; 9491259 AB - Spaceflight results in immunosuppression which is likely due mainly to neurohumoral factors released in response to intermittent stress effects during flight. However, no major non-physiological health problems have been reported during or following spaceflight, but diseases resulting from immunosuppression could occur on long-duration missions and would include bacterial, fungal, and viral infections in addition to increased incidence of neoplasia and autoimmunity. Pharmacokinetics and pharmacodynamics appear to be altered during spaceflight and, as a consequence, alternative drug administration and dosing procedures will need to be developed. Moderate exercise training enhances immune function, but in-flight exercise may affect immunological parameters and immunity in ways not yet ascertained. Hyperosmolality may enhance some immune parameters, and attenuate others especially when associated with dehydration and exercise. Reducing in-flight stress may attenuate flight-induced immunosuppression, but pharmacological interventions may be essential to prevent undesirable immune responses which may occur on long-duration missions to Mars.

AN - 69983592; 11541270 AB - In order to describe quantitatively the pilots' hearing injury by noise in fighter cockpit, the noise level was measured in the cockpit. The temporary threshold shift (TTS) was studied in 20 healthy young man and permanent threshold shift was examined in 166 fighter pilots. The results showed that noise level in cockpit was 110 dBA and TTS after 2 min noise exposure decreased significantly and reached 13 dB at a certain frequency. Its recovery course is faster in low frequency part and language frequency part than that in high frequency part. It was also found that 56% of the 166 pilots suffered from high frequency hearing loss and the percentage increased with flight time. The feature of hearing loss is that it occurs in high frequency at first, then in language frequency, forming a "V" shaped depression at 6 000 Hz. It indicates that cockpit noise may cause permanent threshold shift of hearing.

AN - 69983080; 11536854 AB - Molecular orbital spectral predictions suggest that 2,5,7,10,12,15,17,20-octaaza-21H, 23H-porphine has a visible spectral range closely matching that of chlorophyll-a. Since the octaazaporphine is, in its core, a simple derivative of an (HCN)12 oligomer, this fact, together with its spectral properties, would suggest that it occupies a high rank as a primordial porphinic solar energy transducer for photochemistry essential to life's formation. The demonstration that the mass 324 hexahydrooctaazaporphine is formed in protic media by the cyclotetramerization of imidazol-4-aminohydroxonium ion or the derived nitrenium ion, and that a mass 318 species consonant with that of the Huckel aromatic octaazaporphine is observed in the course of these studies, strongly supports the proposed octaazaporphine synthesis in a prebiotic hydrocyanic acid milieu.

AN - 69982095; 11541261 AB - Ergonomical experiments on speech warning under noise background were carried out in 40 healthy males, aged 20-33. Through the determination of auditory reaction time to the Chinese speech warning under dual-tasks and the subjective evalution of the suitable time length of main warning voice by the subject, the optimum parameters of Chinese speech warning in accordance with space ergonomics were determined. It was found that: suitable time length of main warning voice is 0.35-0.55s, main interval is 0.15-0.35s, speech speed is 4-6 word/s, and sentence interval is 0.2-0.4s. Meanwhile, the analysis of heart rate (HR) and heart rate variability (HRV) demonstrated that the speech warning using aforementioned parameters didn't increase the operator's work load. The results can serve as the objective ergonomical basis and the evaluation criterion for design of speech warning in manned space vehicle.

AN - 69978566; 11536852 AB - The question of whether the production of ammonia, from the reduction of nitrite by iron(II), is compatible with its use in the Strecker synthesis of amino acids, or whether the iron and the cyanide needed for the Strecker synthesis interfere with each other, is addressed. Results show that the presence of iron(II) appears to have little, or no, effect on the Strecker synthesis. The presence of cyanide does interfere with reduction of nitrite, but the reduction proceeds at cyanide/iron ratios of less than 4:1. At ratios of about 2:1 and less there is only a small effect. The reduction of nitrite and the Strecker can be combined to proceed in each other's presence, to yield glycine from a mixture of nitrite, Fe+2, formaldehyde, and cyanide.

AN - 69977744; 11541262 AB - Rice seeds were carried into space by the recoverable satellite. After recovery the seeds were sowed on the earth so as to observe the character performance and genetic variation of their later generations. The preliminary results showed that the main characters of the SP1 generation didn't show significant difference from the control. Among the individual plants of the SP2 generation strong broad-spectrum segregation appeared in the 9 main agronomic characters. Mutation frequency is 4.66%. The individual plants of the SP3 generation were obviously correlated with the SP4 generation in the average character values of the 5 main characters. Stable plant strains were obtained in the SP4 generation. The SP5 and SP6 generations were put into control and polt tests.

AN - 69977057; 11536856 AB - Our previous kinetic and thermodynamic studies upon the reactional system HCHO/HCN/NH3 in aqueous solutions are completed. In the assumed prebiotic conditions of the primitive earth ([HCHO] and [HCN] near 1 g L-1, T = 25 degrees C, pH = 8, [NH3] very low), this system leads to 99.9% of alpha-hydroxyacetonitrile and 0.1% of alpha-aminoacetonitrile (precursor of the alpha-amino acid). The classical base-catalyzed hydration of nitriles, slow and not selective, can not modify significantly this proportion. On the contrary, we found two specific and efficient reactions of alpha-aminonitriles which shift the initial equilibrium in favor of the alpha-aminonitrile pathway. The first reaction catalyzed by formaldehyde generates alpha-aminoamides, precursors of alpha-aminoacids. The second reaction catalyzed by carbon dioxide affords hydantoins, precursors of N-carbamoyl-alpha-aminoacids. In the primitive hydrosphere, where the concentration in carbon dioxide was estimated to be higher than that of formaldehyde, the formation of hydantoins was consequently more efficient. The rates of hydrolysis of the alpha-aminoacetamide and of the hydantoin at pH 8 being very similar, the synthesis of the N-carbamoyl-alpha-amino acid seems then to be the fatal issue of the HCHO/HCN/NH3 system that nature used to perform its evolution. These N-protected alpha-amino acids offer new perspectives in prebiotic chemistry, in particular for the emergence of peptides on the prebiotic earth.

This laboratory system is capable of monitoring changes in growth, accumulation and respiratory activity of biofilms in response to biocidal treatment. The system incorporates a fouling monitor for continuous measuring of the rate of biofilm accumulation (heat transfer resistance), a sensor for monitoring of microbial activity (oxygen meter for monitoring the rate of biofilm respiratory activity), and subsystems necessary for microbial life support and control of operation parameters. Examples of system operation and testing of oxidizing and non-oxidizing biocides are presented.

AN - 69259540; 9490754 AB - Dark-grown hypocotyls of a starch-deficient mutant (NS458) of tobacco (Nicotiana sylvestris) lack amyloplasts and plastid sedimentation, and have severely reduced gravitropism. However, gravitropism improved dramatically when NS458 seedlings were grown in the light. To determine the extent of this improvement and whether mutant hypocotyls contain sedimented amyloplasts, gravitropic sensitivity (induction time and intermittent stimulation) and plastid size and position in the endodermis were measured in seedlings grown for 8 d in the light. Light-grown NS458 hypocotyls were gravitropic but were less sensitive than the wild type (WT). Starch occupied 10% of the volume of NS458 plastids grown in both the light and the dark, whereas WT plastids were essentially filled with starch in both treatments. Light increased plastid size twice as much in the mutant as in the WT. Plastids in light-grown NS458 were sedimented, presumably because of their larger size and greater total starch content. The induction by light of plastid sedimentation in NS458 provides new evidence for the role of plastid mass and sedimentation in stem gravitropic sensing. Because the mutant is not as sensitive as the WT, NS458 plastids may not have sufficient mass to provide full gravitropic sensitivity.

AN - 69257313; 11536873 AB - The N-1-naphthylphthalamic acid (NPA)-binding protein is part of the auxin efflux carrier, the protein complex that controls polar auxin transport in plant tissues. This study tested the hypothesis that the NPA-binding protein (NBP) is associated with the actin cytoskeleton in vitro and that an intact actin cytoskeleton is required for polar auxin transport in vivo. Cytoskeletal polymerization was altered in extracts of zucchini hypocotyls with reagents that stabilized either the polymeric or monomeric forms of actin or tubulin. Phalloidin treatment altered actin polymerization, as demonstrated by immunoblot analyses following native and denaturing electrophoresis. Phalloidin increased both filamentous actin (F-actin) and NPA-binding activity, while cytochalasin D and Tris decreased both F-actin and NPA-binding activity in cytoskeletal pellets. The microtubule stabilizing drug taxol increased pelletable tubulin, but did not alter either the amount of pelletable actin or NPA-binding activity. Treatment of etiolated zucchini hypocotyls with cytochalasin D decreased the amount of auxin transport and its regulation by NPA. These experimental results are consistent with an in vitro actin cytoskeletal association of the NPA-binding protein and with the requirement of an intact actin cytoskeleton for maximal polar auxin transport in vivo.

Planar microstructures in quartz and feldspars and shock vitrification of the rock are the most common shock metamorphic features encountered; no diaplectic quartz was seen, but minor maskelynite occurs. Shatter cones are common and suggest minimum P of 4 + or - 2 GPa. The relative frequency of low-index planar microstructures with specific crystallographic orientations in quartz are correlated with results from shock barometric experiments to estimate peak shock P; in general, there is a decrease in shock P from approximately 20-25 GPa in east-central Patterson Island to approximately 5-10 GPa at the W shore of this island and on Mortimer Island. The shock attenuation gradient is approximately 4.5 GPa/km, but the shock attenuation is concentric only over the W part of the archipelago. Based on XRD results, residual post-impact T were high enough to cause annealing of submicroscopic damage in shocked quartz.

This technique accounts for processing effects such as main and external field removal. An a priori model consisting of an ocean-continent magnetic contrast, oceanic topography, and remanent magnetization in the Cretaceous quiet zones is constructed using equivalent source dipoles. Previous investigations using similar models utilize only forward modeling procedures. We show how this a priori model can be modified so that the resulting computed field, after removal of spherical harmonics below some specified degree ("main field" removal) and along track filtering ("external field" removal), matches that of the robust POGO-Magsat anomaly map in a least squares sense. The dependence of the final model on the a priori information is also investigated. Between degrees 20 and 60 the final models are found to be almost identical for reasonable a priori conditions. An example from the Gulf of Mexico and surrounding Gulf Coast region serves to illustrate the utility of the technique. High heat flow,> 40 degrees C/km, is observed in much of the Gulf Coast region. The example suggests that the elevated heat flow persists at depth and has elevated the Curie point. Copyright 1998 by the American Geophysical Union.

Since these coupled errors in MSU data differ between successive satellites, it is necessary to make compensatory adjustments to these multisatellite data sets in order to determine long-term global temperature change. With the aid of the observations during overlapping periods of successive satellites, we can determine such adjustments and use them to account for the coupled errors in the long-term time series of MSU Ch 2 global temperature. In turn, these adjusted MSU Ch 2 data sets can be used to yield global temperature trend. In a pioneering study, Spencer and Christy (SC) (1990) developed a procedure to derive the global temperature trend from MSU Ch 2 data. Such a procedure can leave unaccounted residual errors in the time series of the temperature anomalies deduced by SC, which could lead to a spurious long-term temperature trend derived from their analysis. In the present study, we have developed a method that avoids the shortcomings of the SC procedure, the magnitude of the coupled errors is not determined explicitly. Furthermore, based on some assumptions, these coupled errors are eliminated in three separate steps. Such a procedure can leave unaccounted residual errors in the time series of the temperature anomalies deduced by SC, which could lead to a spurious long-term temperature trend derived from their analysis. In the present study, we have developed a method that avoids the shortcomings of the SC procedures. Based on our analysis, we find there is a global warming of 0.23+/-0.12 K between 1980 and 1991. Also, in this study, the time series of global temperature anomalies constructed by removing the global mean annual temperature cycle compares favorably with a similar time series obtained from conventional observations of temperature.

This research has combined meteorological, remote sensing, and coastal expertise from the University of Wisconsin (UW) and Louisiana State University (LSU). Analyzed data sets include remotely sensed radiometric data (AVHRR on NOAA-12,13,14, Multispectral Atmospheric Mapping Sensor (MAMS) and MODIS Airborne Simulator (MAS) on NASA ER-2), U.S. Army Corps of Engineers (USACE) water level data, water quality data from the Coastal Studies Institute (CSI) at LSU, USACE river discharge data, National Weather Service (NWS) and CSI wind in sitzi measurements, geomorphic measurements from aerial photography (NASA ER-2 and Learjet), and CSI ground based sediment burial pipes (for monitoring topographic change along the Louisiana coast) and sediment cores. The work reported here- in is a continuation of an initial investigation into coastal Louisiana landform modification by cold front systems. That initial effort demonstrated the importance of cold front winds in the Atchafalaya Bay sediment plume distribution (Moeller et al.), documented the sediment transport and deposition process of the western Louisiana coast (Huh et al.) and developed tools (e.g. water types identification, suspended solids estimation) from multispectral radiometric data for application to the current study. This study has extended that work, developing a Geomorphic Impact Index (GI(sup 2)) for relating atmospheric forcing to coastal response and new tools to measure water motion and sediment transport.

A variety of instruments sensitive to different parts of the electromagnetic spectrum take what the human eye detects as a flat, white desert and provide data sets rich in scientific information. Image-based maps of ice sheets are becoming commonplace and have become an integral component of field work. More than a pretty picture, the digital character of the satellite data from these instruments has become fundamental to the production of elevation, motion, accumulation, and reflectance data sets. Visible imagery shows the scientist a wealth of features that offer clues to the history and current behavior of the ice sheet. Radar and microwave imagery provide information from beneath the surface and have been used to estimate snow accumulation rates. Interferometry principles have recently been applied to measure surface topography and ice motion with unparalleled precision. Nonimaging instruments also keep a watchful eye, monitoring the ice sheet for indications of growth or shrinkage. Further expansion of the uses of satellite data is anticipated in the future.

N1 - Last updated - 2011-12-13 ER - TY - JOUR T1 - Proposed minimum requirements for the operational characteristics and testing of submersible atmosphere monitoring and control units. AN - 79643255; 11876195 AB - The design of a submersible and its myriad subsystems is a complex undertaking made more difficult by the interval between new designs. Special applications also tax the life support designer, such as diver lock-out submersibles, which are far more complex than one-atmosphere vehicles. The long intervals between designs generally means that a new generation of designers will be approaching the problems without the benefit of the knowledge and experience of the past generation of designers. This new generation of designers often has greatly improved technologies and materials at hand. Yet in the application of the new technology, life support issues that were addressed and resolved in the old and proven designs get lost in the process of redesign due to the lack of experience in the life support arena. Competent engineers operating outside their normal area of expertise can generate costly or even deadly mistakes. For this reason a set of performance requirements that details the critical functions of the life support systems is needed. Atmosphere control electronics can seriously impact the safety of the submersible crew. The triple dangers of fire, toxicity, and asphyxia demand that the electronics that monitor and control the submarine compartment atmosphere have certain characteristics. These characteristics are easily captured in a performance requirement. This article will present a set of proposed minimum performance requirements, with the goal of establishing a dialog for the creation of guidelines for the classification, rating, design, and testing of embedded electronics for life support systems used in submersible applications. These guidelines will serve as the foundation for the later creation of a set of industry specifications.

AN - 79642739; 11876193 AB - Long hyperbaric exposures of humans, at pressures in excess of 2.5 atmospheres, require that the oxygen concentration of the breathing gas be maintained at levels less than atmospheric air, in order to prevent pulmonary oxygen toxicity. Carbon dioxide produced by humans must be removed from the breathing gas of closed environments. Differential permeability gas separation devices can be used to reduce the concentrations of carbon dioxide and oxygen in recirculating nitrogen/oxygen atmospheres. The application of these devices can eliminate the requirement for nitrogen to dilute oxygen, and reduce, or eliminate, the requirement for carbon dioxide absorbents. The use of differential permeability gas separation devices for the production of nitrogen/oxygen breathing gas mixtures for divers, using air as a source gas, can produce mixtures with unacceptably high levels of carbon dioxide.

AN - 79638044; 11876204 AB - Results are presented from constructed wetland systems designed to treat wastewater in Akumal, Quintana Roo, Mexico, which was developed after prior experience with the Biosphere 2 closed ecological system wetland systems. These systems illustrate the congruity of needs in advanced life support systems and in solving social and environmental problems in developing countries. For sustainable food production for life support, closed ecological systems need to bioregenerate and recycle nutrient-rich wastewater. Developing countries need low-tech ecologically engineered systems that minimize requirements for capital, nonrenewable energy, and technical expertise. Biosphere 2's surface flow wetlands covered 41 m2 and treated the wastewater from eight inhabitants, laboratories, and domestic animals during the 1991-1993 closure experiment. The Mexican wetlands are subsurface flow wetlands using limestone gravel as substrate. Two wetland systems treat sewage from 40 people and cover 131 m2. During the initial year of operation, the wetlands in Akumal reduced BOD 86%, TSS 39%, total P 80%, total N 75%, and coliform bacteria 99.85%. Phosphorus uptake in the limestone gravel was around 6 mg/kg. High biodiversity, with 70 plant species, was maintained in the Akumal constructed wetlands 1.5 years after planting. The Shannon diversity index was 4.7 (base 2). Plant diversity was slightly less than tropical forest ecosystems of the region, but far greater than biodiversity in natural mangrove wetlands.

AN - 79637945; 11876194 AB - Air purification in submarines was introduced towards the end of World War II and was limited to the use of soda lime for the removal of carbon dioxide and oxygen candles for the regeneration of oxygen. The next major advances came with the advent of nuclear-powered submarines. These included the development of regenerative and, sometimes, energy-intensive processes for comprehensive atmosphere revitalization. With the present development of conventional submarines using air-independent propulsion there is a requirement for air purification similar to that of the nuclear-powered submarines but it is constrained by limited power and space. Some progress has been made in the development of new technology and the adoption of air purification equipment used in the nuclear-powered submarines for this application.

Multicomponent equilibrium modeling. AN - 79635128; 11542650 AB - A thermodynamic model is developed to predict adsorption equilibrium in the International Space Station water processor's multifiltration beds. The model predicts multicomponent adsorption equilibrium behavior using single-component isotherm parameters and fictitious components representing the background matrix. The fictitious components are determined by fitting total organic carbon and tracer isotherms with the ideal adsorbed solution theory. Multicomponent isotherms using a wastewater with high surfactant and organic compound concentrations are used to validate the equilibrium description on a coconut-shell-based granular activated carbon (GAC), coal-based GAC, and a polymeric adsorbent.

AN - 79632352; 11876198 AB - Manned submersibles and atmospheric diving suits share a number of characteristics, with the most obvious being the rigid hull structure required to maintain a one-atmosphere cabin pressure in the presence of high external pressures. The rigid pressure hull results in a fixed internal volume that allow a simple, mechanical means of precisely controlling the input of make up oxygen to replace that metabolized by the occupant(s). The field-proven life support hardware described in this article is peculiar to monobaric systems but may have applications in other manned cabin situations where a fixed volume is present--regardless of maintenance pressure. Also briefly described is a state-of-the-art life support monitoring system developed by Nuytco Research Ltd. under contract to the National Energy Board of Canada. The "Biosensor" is thought to have broad application potential in the manned undersea field.

AN - 79628185; 11542590 AB - A survey of the natural background dose equivalent received by Canadian Forces aircrew was conducted using neutron-sensitive bubble detectors (BDs) as the primary detection tool. Since this study was a new application for these detectors, the BD response to neutron dose equivalent (RD) was extended from thermal to 500 MeV in neutron energy. Based upon the extended RD, it was shown that the manufacturer's calibration can be scaled by 1.5 +/- 0.5 to give a BD sensitivity that takes into account recently recommended fluence-to-neutron dose equivalent conversion functions and the cosmogenic neutron spectrum encountered at jet altitudes. An investigation of the effects of systematic bias caused by the cabin environment (i.e., temperature, pressure and relative humidity) on the in-flight measurements was also conducted. Both simulated and actual aircraft climate tests indicated that the detectors are insensitive to the pressure and relative humidity variations encountered during routine jet aircraft operations. Long term conditioning tests also confirmed that the BD-PND model of detector is sensitive to variations in temperature to within +/- 20%. As part of the testing process, the in-flight measurements also demonstrated that the neutron dose equivalent is distributed uniformly throughout a Boeing 707 jet aircraft, indicating that both pilots and flight attendants are exposed to the same neutron field intensity to within experimental uncertainty.

AN - 79625352; 11543361 AB - Measurements of 90Sr in human bone of inhabitants of the Techa river region were started in 1951, and since 1974 the Techa river population has been studied with a whole-body counter. One of the dosimetric tasks that could be decided using data on 90Sr measurements is direct evaluation of strontium transfer to the fetus from the maternal skeleton. Six cases were selected for which 90Sr measurements were available both for stillborn infants and their mothers. The ratio of 90Sr concentrations in fetal bone to maternal bone for the year of pregnancy has been evaluated. Two clusters of values were found and the difference between clusters could be explained by age-dependent features of maternal bone formation and remodelling. When the mother's 90Sr intake occurred in the period of intensive compact bone growth, the transfer coefficient was very low (0.012-0.032). If 90Sr ingestion occurred during the woman's reproductive age, the transfer to fetus was equal to 0.21-0.26.

When the National Aeronautics and Space Administration was created by an act of Congress in 1958, its charter required the agency to "...provide for the widest practicable and appropriate dissemination of information concerning its activities and the results thereof." Part of that responsibility includes introducing students to the scientific results of planetary exploration. This volume is designed to help meet this goal. The activities are written either to supplement or to introduce topics usually encountered in earth science courses. The exercises are grouped into five units: (1) introduction to geologic processes; (2) impact cratering activities; (3) planetary atmospheres, (4) planetary surfaces, and (5) geologic mapping. Although each exercise is intended to "stand alone," students will benefit from having worked some of the prior exercises. For example, it would be difficult for students to work exercises in planetary geologic mapping without some knowledge of geologic processes and planetary surfaces. The suggested introductory exercises are noted at the beginning of each exercise. Depending on the instructor, activities can be adapted to most levels of instruction by modifying the questions and adjusting the expectations for answers. A list of suggested correlations of activities with topics commonly covered in earth science courses is included for the convenience of the instructor. (Contains 91 figures.)

East-to-west groundwater flow from San Andres Mountain-front recharge areas across the pediment slope is complex as a result of variable hydrostratigraphy and fracturing within the bedrock aquifer. Previous investigations have indicated that flow across the pediment is enhanced by a saturated alluvial paleochannel eroded in the bedrock and infilled with post-Laramide detritus derived from the Bear Canyon fold and thrust belt. The paleochannel contains Santa Fe Group alluvial-fan deposits, and is locally intercepted by the groundwater table to create a saturated alluvial hydrostratigraphic unit. Elevated hydraulic conductivities within this proposed unit have been used to conceptualize groundwater flow within a three-dimensional site-wide bedrock groundwater model. A 1997 field study evaluated a narrow midsection of the paleochannel formed as a result of confining hydrogeologic conditions. A pumping well (IS-1), 1000 ft Westbay (super R) multiport monitoring well (BLM-33), and several existing conventional wells were utilized for an aquifer test to delineate hydrostratigraphic units and groundwater flow. A stratified sequence of five hydrostratigraphic units (HUs) were correlated across the study area within Oligocene volcanic bedrock between the groundwater table at 300 ft and 1020 ft. These units were designated: Santa Fe Group alluvium, 150 ft thick (HU-5). Study results indicate a minimal thickness of saturated alluvium and no enhancement of groundwater flow. Pervasive carbonate cementation of the saturated alluvial matrix drastically reduces the porosity of the alluvium to that of fractured bedrock (<5%). A step drawdown test and continuous rate-pumping test were performed at well IS-1 within the relatively productive HU-4. Groundwater depths were monitored using an automated data-logging system that allowed the simultaneous measurement of formation fluid pressures at several locations within Westbay (super R) multiport and adjacent aquifer test wells. Pump test data calculations yielded hydraulic parameters for HU-4 of: K=2.1X10 (super -6) to 1.4X10 (super -5) ft/sec; T=58.6 to 386.5 ft (super 2) /day; and S=1.5X10 (super -5) to 1.4X10 (super -4) . Groundwater is hosted within a leaking, semi-confined, fractured-bedrock aquifer that was dewatered during the pre-test development and post-test recovery phases. The hydrostratigraphic data generated for this study warrant revision of the existing groundwater model. Groundwater heads must be recalibrated to simulate the semi-confined nature of bedrock-hosted groundwater, as opposed to unconfined saturated alluvium. Further definition of HU-1 and HU-2 hydraulic parameters within the upper 120 ft of the aquifer are required to conceptualize the previously undefined hydrostratigraphic and groundwater flow data.

AN - 69991291; 11540466 AB - A biofilter composed of a scrubber, a hydroponic planting system, and an aquatic system with green plants as a base maintained air quality within part of a modern office building. The scrubber was composed of five parallel fiberglass modules with external faces of porous lava rock. The face, largely covered with mosses, was wetted by recirculating water. Air was drawn through the scrubber and the immediately adjacent hydroponic region by a dedicated air handling system. The system was challenged for 4 weeks with three common indoor organic pollutants and removed significant amounts of all compounds. A single pass through the scrubber removed 10% of the trichloroethylene and 50% of the toluene. A single pass lowered formaldehyde air concentrations to 13 micrograms m-3 irrespective of influent levels (ranging between 30 and 90 micrograms m-3). The aquatic system accumulated trichloroethylene but neither toluene nor formaldehyde, suggesting the rapid breakdown of these materials. The botanical components removed some pollutants.

AN - 69991241; 11540465 AB - The biodegradation of inedible biomass and the recovery of nutrients from hydroponically grown tomato plant material were investigated under various growth conditions of activated sludge and the fungus Phanerochaete chrysosporium. The experiments were carried out in shaker flasks at three incubation temperatures (25 degrees C, 40 degrees C, and 60 degrees C for the activated sludge and 25 degrees C, 40 degrees C, and 50 degrees C for the fungi) with heat-pretreated samples at 150 degrees C for 30 min, and without pretreatment of the inedible residues. Under the experimental conditions tested, both cultures exhibited similar performance in terms of solids reduction and nutrient recovery. Solids reduction as high as 70% was obtained in both systems. Most of the solids degradation occurred the first 16 days of incubation. Cellulose degradation reached about 90% but no significant reduction in the solids lignin content was observed. Recovery of nitrogen (as NO2-N and NO3-N) and other micronutrients was sufficiently high and was accompanied by an average 70% reduction in COD, indicating that the final effluent is suitable for hydroponic plant growth. Incubation temperature had a minimal effect on solids degradation but appeared to influence the leachability of certain nutrients.

AN - 69989162; 11540461 AB - The development of the International Space Station (ISS) Water Reclamation and Management (WRM) system has been supported through integrated testing at NASA/Marshall Space Flight Center (MSFC). Assessment of the viral removal capabilities of the ISS water processor was performed as part of the hardware performance evaluation. For the Viral Challenge Test, a known concentration of viruses was mixed with human-generated wastewater and reclaimed using the ISS Water Processor. The composition and concentrations of the different wastewaters used for this test represented the combination of contaminants expected to be found in the wastewater that will be collected and recycled on board the ISS. The results from the Viral Challenge Test clearly showed that the ISS WRM has the capacity to reduce the concentration of viruses in the wastewater by 12 log10 units.

AN - 69988394; 11540463 AB - Tests are being conducted at NASA/Marshall Space Flight Center with the purpose of assessing possible water quality changes and potential biofilm formation in the water distribution system of the International Space Station (ISS) Water Recovery and Management (WRM) System. The Biofilm Life Test and Water Degradation Study (WDS) will be discussed in this article. The Biofilm Life Test examines the potential for biofilm formation in the ISS water distribution plumbing and storage tanks. The test has two independent loops; one simulates the waste water prior to the processing by the ISS Water Processor (WP), and the other simulates the processed (clean) water after the ISS WP. The test setup design incorporates tube lengths and angles, material types, flow rates, and recommended hardware that represent the ISS water distribution system. The WDS purpose is to assess changes in water quality (chemical and microbiological) during stagnant, long-term storage in distribution lines. Test results demonstrate that prior to the operation of the ISS WP, water can be stored in the ISS water distribution lines.

AN - 69987111; 11540458 AB - An aquatic habitat of 1.7 L was designed to support three adult fish (medaka, Oryzias latipes) for 100 days with minimal exchange of water. The Aquatic Habitat consisted of a specimen chamber (800 ml), biofilter chamber and associated tubing (250 ml), and a microbial control chamber (650 ml), filled with water. Fish were fed daily. The water was oxygenated via a hollow fiber oxygenator. The liquid flow rate was 30 ml/min and the air flow as 100 ml/min. Six units were established. Fish mortalities, when they occurred, were often associated with failures of the water flow system and lack of oxygen being supplied from the oxygenator. The bacterial community, from three "Bio-Chem Stars" inoculated from a medaka aquarium, transformed ammonia and prevented toxic conditions from occurring. The bacteria were grazed by protozoa, rotifers, nematodes, oligochaetes, and ostracods in all habitats. In three of six habitats, Daphnia and amphipods had been purposely introduced; their survival was variable. Biofilm and settled particulates accumulated during the experiment and eventually exceeded the weight of the fish. Of six units, two supported the initial fish through the whole experiment, another experienced fish mortalities, but replacement fish survived, and three units did not support fish survival for the 100 days. Our results demonstrated the feasibility of the system, but many improvements are needed such as improved water flow and oxygen monitoring to assure prompt corrective action.

AN - 69984483; 11541134 AB - Two separate experiments were conducted to investigate plant growth and mineral composition of potatoes (Solanum tuberosum L.) at varied solution concentrations of nitrate (NO3-) and ammonium (NH4+). Each experiment evaluated five nitrogen (N) concentrations of 0.5, 2, 4, 8, and 12 mM, which were maintained with a non-recirculating nutrient film system in controlled environment. Plants were harvested on day 42 with NO3-; and day 35 with NH4+ after transplanting of tissue culture plantlets, and growth measurements were taken as leaf area, tuber number, and dry weights of different parts. With NO3-, plant growth was greatest and similar at 2, 4, and 8 mM of N whereas with NH4+, plant growth was best only at 2 and 4 mM of N. At 12 mM of N, plants exhibited interveinal ammonium toxicity with NH4+ nutrition, but healthy growth appearance with NO3- nutrition. With either N form, total N concentrations in tissues tended to increase with increased N concentrations, and tissue phosphorus (P) concentrations were reduced at 0.5 and 2 mM of N. Tissue concentrations of calcium (Ca), magnesium (Mg), and sulfur (S) changed only slightly at particular N concentrations, yet changed substantially with different N forms. The data indicate that the optimal ranges of N concentrations in both solution and tissues are wider and higher with NO3- than with NH4+ nutrition, and thus a careful control of NH4+ concentrations is necessary to minimize possible ammonium toxicity to potato plants.

AN - 69984309; 11540469 AB - Semiclosed circuit underwater breathing apparatus (UBAs) are far more conserving of limited gas supplies than either steady-flow, open circuit or demand, open circuit systems. Semiclosed systems recirculate most of the diver's breathing gases, while injecting only a small percentage of the total circuit flow with a fresh makeup supply. The fresh, injected gas supply delivers the necessary makeup to compensate for the oxygen that the diver consumes during each pass through the lungs. This gas-conserving feature makes the utility for semiclosed UBAs for long-duration, deep diving applications more practical than either of the open circuit designs. However, although more gas conservative, these systems maintain variable oxygen levels during a dive that can fluctuate widely with changes in the diver's activity level, depth of the dive, makeup gas composition, or variations in the total circuit volume. It is essential that the oxygen levels in the circuit always remain within physiologically safe limits; neither too low to avoid the onset of hypoxia, nor too high to risk oxygen toxicity. This article presents an analytical assessment of the oxygen levels in semiclosed UBAs. This model allows the designers of semiclosed circuits to predict the effects of UBA circuit volumes, makeup gas compositions, injection rates for the makeup gas, diver depths, and initial circuit oxygen levels on the time-dependent levels of oxygen in these circuits. By using this analytical tool, judicious selection of these design variables can result in the most efficient utilization of the fresh gas supply carried by the diver, and ensure the safe operation of these UBA designs.

AN - 69981739; 11540590 AB - Several experiments were carried out to test responses of a Super-Dwarf cultivar of wheat (Triticum aestivum L.) to various environmental parameters that were anticipated to be present in our attempts to grow the wheat in a small growth chamber on the Russian Space Station, Mir, or that proved to be present in a 1995 trial space experiment. Under low photosynthetic photon flux (40-400 micromoles m-2 s-1 PPF), development (e.g. anthesis) was retarded, but heads (often sterile) always formed, even if light was so low that plants died before the heads could mature. Longer photoperiods promoted flowering, but night interruptions combined with short days did not provoke a long-day response as occurs with true long-day plants. The long-day effect could prove to be a summation of photosynthetic products. Heat stress (40 degrees C for 1-24 h) did not influence flowering but killed plants that were 13-16-day-old (no effect on younger plants). Concentrations of iodine or silver-fluoride disinfectants present in the water used for plants on Mir (1.0-4.0 mg L-1) did not affect plant growth although higher concentrations (8.0-1.6 mg L-1) were inhibitory. GA3 or indoleacetic acid applied every other day at concentrations from 1.0 x 10(-6) mg L-1 to 3.162 x 10(-4) mg L-1 did not change the height of Super-Dwarf wheat, suggesting that this cultivar is not a gibberellin mutant.

AN - 69977485; 11541257 AB - It has been hypothesized that the sedimentation of amyloplasts within root cap cells is the primary event in the plant gravisensory-signal transduction cascade. Statolith sedimentation, with its ability to generate weighty mechanical signals, is a legitimate means for organisms to discriminate the direction of the gravity vector. However, it has been demonstrated that starchless mutants with reduced statolith densities maintain some ability to sense gravity, calling into question the statolith sedimentation hypothesis. Here we report on the presence of a beta 1 integrin-like protein localized inside amyloplasts of tobacco NT-1 suspension culture, callus cells, and whole-root caps. Two different antibodies to the beta 1 integrin, one to the cytoplasmic domain and one to the extracellular domain, localize in the vicinity of the starch grains within amyloplasts of NT-1. Biochemical data reveals a 110-kDa protein immunoprecipitated from membrane fractions of NT-1 suspension culture indicating size homology to known beta 1 integrin in animals. This study provides the first direct evidence for the possibility of integrin-mediated signal transduction in the perception of gravity by higher plants. An integrin-mediated pathway, initiated by starch grain sedimentation within the amyloplast, may provide the signal amplification necessary to explain the gravitropic response in starch-depleted cultivars.

AN - 69259501; 11541682 AB - Green microalgae are likely to play an important role in bioregenerative systems for producing food and converting CO2 to O2 in a controlled ecological life support system (CELSS). In the present study, a method for evaluating the effects of environmental variables on the multiplication rate of microalgal cells was developed to determine the optimum culture condition for a microalgal culture system that can function effectively in the CELSS. The microalga, Euglena gracilis, was cultured in water droplets (3 microliters in liquid volume each) in a vessel (25 ml in air volume) in which the CO2 and O2 concentrations were controlled. The number of Euglena cells cultured at CO2 concentrations ranging from 2% to 6%, O2 concentrations ranging from 5% to 20%, and PPF levels ranging from 50 to 100 micromoles m-2 s-1 was monitored by using a video camera and a microscope. The multiplication rate of cells was highest and the cell number increased by 8.3 times during 48 h under a condition of 4% CO2, 21% O2 and 100 micromoles m-2 s-1 PPF. The multiplication rate of the cells was highest at 4% CO2, followed by 6% and 2% CO2, and it decreased with decreasing O2 concentration and decreasing PPF.

AN - 69259243; 11541670 AB - Light-emitting diodes (LEDS) are a potential lighting source for space-based plant growth systems because of their small mass, operational longevity, and spectral quality. However, the vegetative and reproductive growth and development of plants grown under narrow spectrum LEDs must be characterized before acceptance of LEDS as an alternative light source for growing plants. The objectives of this study were 1) to determine the feasibility of using red LEDS for growing Arabidopsis thaliana L. through a full seed-bearing generation, and 2) to determine if supplemental blue radiation is necessary for growth and seed production. Arabidopsis grown under red LEDS alone produced viable seed, but these plants had abnormal leaf morphology and delayed flowering in comparison to control plants grown under broad spectrum white light or red LEDS supplemented with blue light.

AN - 69258821; 11541669 AB - Cucumbers (Cucumis sativus L. cv. Naoyosi) were grown hydroponically at air temperatures of 28/24 degrees C (D/N) and photosynthetic photon flux (PPF) of 300 micromoles m-2 s-1, in a walk-in type growth cabinet equipped with 3-band fluorescent lamps. Plants were subjected to supplemental blue lighting applied daily just before the 14-h photoperiod (morning twilight) under PPFs of 0, 10, 30, 100, and 200 micromoles m-2 s-1. Treatment periods were 0, 5, 30, or 120 min. Growth and morphological parameters were measured after 12 and 14 days of treatment. On the 13th day of treatment, the stomatal conductance (gs), transpiration rate (Tr), and net photosynthetic rate (Pn) were measured under 3-band fluorescent lamps at a PPF of 200 micromoles m-2 s-1. After 17-19 days of treatment, changes in Pn effected by supplemental blue light were measured continuously for 30 min. Treatment with 5 min of blue lighting promoted more growth than treatment for 30 or 120 min. Similarly, gs, Tr, and Pn were the greatest in plants grown with supplemental blue light of 30 micromoles m-2 s-1 and 100 micromoles m-2 s-1 PPF for 5 min. Pn in plants grown under blue light of 30 micromoles m-2 s-1 for 5 min increased by 60% compared with that of control plants.

AN - 69258792; 11541668 AB - Blue photons are energetically expensive so the most energy-efficient lamps contain the least blue light. Blue photons are not used efficiently in photosynthesis, but blue light has dramatic effects on plant development. We studied the growth and development of soybean, wheat, and lettuce plants under high-pressure sodium and metal halide lamps with yellow filters creating five fractions of blue light (0.5%, 3.5%, 6%, 1 8%, and 26% blue) at 500 micromoles m-2 s-1 and (< 0.1%, 1.7%, 6%, 12%, and 26%) at 200 mol m-2 s-1. The response was species dependent. Lettuce was highly sensitive to blue light fraction and had an optimum dry weight and leaf area at about 6% blue, but results were complicated by sensitivity to lamp type. Wheat and soybean were less sensitive to blue light, but dry mass and leaf area decreased steadily with increasing blue light. Blue light fraction significantly affected specific leaf area (SLA, m2 kg-1) and chlorophyll in lettuce, but had no significant effect on wheat and soybeans. The data suggest that lettuce benefits from some added blue light, but soybean and wheat may not.

AN - 69258734; 11541393 AB - Formation of microbial biofilms on surfaces of a wide range of materials being considered as candidates for use on the International Space Station was investigated. The materials included a fibre-reinforced polymeric composite, an adhesive sealant, a polyimide insulation foam, teflon cable insulation, titanium, and an aliphatic polyurethane coating. They were exposed to a natural mixed population of bacteria under controlled conditions of temperature and relative humidity (RH). Biofilms formed on the surfaces of the materials at a wide range of temperatures and RHs. The biofilm population was dominated by Pseudomonas aeruginosa, Ochrobactrum anthropi, Alcaligenes denitrificans, Xanthomonas maltophila, and Vibrio harveyi. The biocide, diiodomethyl-p-tolyl sulfone, impregnated in the polyurethane coating, was ineffective against microbial colonization and growth. Degradation of the polyurethane coatings was monitored with electrochemical impedance spectroscopy (EIS). The impedance spectra indicated that microbial degradation of the coating occurred in several stages. The initial decreases in impedance were due to the transport of water and solutes into the polymeric matrices. Further decreases were a result of polymer degradation by microorganisms. Our data showed that these candidate materials for space application are susceptible to biofilm formation and subsequent degradation. Our study suggests that candidate materials for use in space missions need to be carefully evaluated for their susceptibility to microbial biofilm formation and biodegradation.

AN - 69257841; 11541677 AB - In order to characterize environmental variables inside a plant canopy under artificial lighting in the CELSS, we investigated the effects of light intensity and air velocity on air temperature, water vapor pressure, and CO2 concentration inside a plant canopy. Under a PPF of 500 micromoles m-2 s-1, air temperature was 2-3 degrees C higher, water vapor pressure was 0.6 kPa higher, and CO2 concentration was 25-35 micromoles mol-1 lower at heights ranging from 0 to 30 mm below the canopy than at a height 60 mm above the canopy. Increasing the PPF increased air temperature and water vapor pressure and decreased CO2 concentration inside the canopy. The air temperature was lower and the CO2 concentration was higher inside the canopy at an air velocity of 0.3 m s-1 than at an air velocity of 0.1 m s-1. The environmental variables inside the canopy under a high light intensity were characterized by higher air temperature, higher vapor pressure, and lower CO2 concentration than those outside the canopy.

AN - 69257796; 11541667 AB - As part of NASA's Advanced Life Support Program, the Breadboard Project at Kennedy Space Center is investigating the feasibility of using crop plants in bioregenerative life support systems (BLSS) for long-duration space missions. Several types of electric lamps have been tested to provide radiant energy for plants in a BLSS. These lamps vary greatly in terms of spectral quality resulting in differences in growth and morphology of the plants tested. Broad spectrum or "white" light sources (e.g., metal halide and fluorescent lamps) provide an adequate spectrum for normal growth and morphology; however, they are not as electrically efficient as are low-pressure sodium (LPS) or high-pressure sodium (HPS) lamps. Although LPS and HPS, as well as the newly tested red light-emitting diodes (LEDs), have good photosynthetically active radiation (PAR) efficiencies, they are deficient in blue light. Results with several of the crops tested for BLSS (wheat, potato, soybean, lettuce, and radish) have shown a minimum amount of blue light (approximately 30 micromoles m-2 s-1) is necessary for normal growth and development. For example, the lack of sufficient blue light in these lamps has resulted in increased stem elongation and significant reductions in photosynthesis and yield. To avoid problems with blue-deficient lamps and maximize yield, sufficient intensity of HPS or blue light supplementation with red LEDs or LPS lamps is required to meet spectral requirements of crops for BLSS.

AN - 69256357; 11541674 AB - Due to the high cost of habitable real estate associated with space travel and colonization, and the ultimate use of plants as the primary method of life support, it is necessary to develop cultivation methods whereby the highest sustainable level of productivity is achieved within the least amount of space. It is well known that in a dense plant canopy, lower leaves become shaded from above and eventually no longer contribute to carbon gain. In fact, they contribute to net respiratory carbon losses. One method of improving biomass production is to introduce light of suitable quantity and quality to the inner canopy, thereby utilizing unused photosynthetic capacity. By coupling microwave-powered lights to 100-mm-diameter glass tubes lined with 3M Optical Lighting Film, light with a spectral quality similar to that of sunlight was delivered to the inner canopy of a developing soybean crop. Results indicated that increases in productivity of 23-87%, as measured by CO2 assimilation, can be achieved in dense plant canopies (LAI approximately 6) when overhead lighting (40O-1200 micromoles m-2 s-1) is supplemented with inner canopy illumination.

The crew is limited to three because the Russian Soyuz vehicle that will remain docked to the ISS can only hold three people. It is imperative that the crew members be able to return to Earth if there is a medical emergency or if other complications arise. In development at this time is a Crew Return Vehicle that will be able to hold up to seven crew members. This brief contains an activity to construct a parafoil similar to the one that will be used for the International Space Station crew return vehicle, the X-38.

AN - 62301474; ED448037 AB - Space walking has captured the imagination of generations of children and adults since science fiction authors first placed their characters on the moon. The guide begins with brief discussions of the space environment, the history of space walking, NASA's current spacesuit, and work that astronauts do during spacewalks. These are followed by a technology education design brief that challenges students to design and build a spacesuit prototype for an extra-terrestrial environment no human has ever visited before. In the process of doing this, students will have to investigate the properties of that environment and determine what protective measures must be taken to permit a future explorer to work there safely. Once accomplished, students choose materials and technologies that can be used for constructing and testing the prototype. The design brief is followed by Teacher Tech Briefs that provide a source of ideas on how to build a spacesuit test apparatus and by Exploration Briefs that provide activity frameworks to help students understand important topics in spacesuit design. The guide concludes with a glossary of terms, a suggested reading list, NASA educational resources including electronic resources, and an evaluation questionnaire. (Contains 12 references.)

Ice stream B has widened by 4 kilometers, at a rate much faster than suggested by models, and has decreased in speed by 50 percent. The ice ridge between ice streams B and C has eroded 14 kilometers. These changes, along with changes in the crevassing around Crary Ice Rise, imply that this region's velocity field shifted during this century.

Three years of ice temperature data at Lake Bonney (1993-1995) show that the ice contained 20% liquid water located at 1 to 2.5 m below the ice surface near the end of all 3 melting seasons. Liquid water fractions at Lake Hoare were low (15%) throughout the ice column in 1986. In 1987 and 1988 liquid water fractions increased to a maxima of 70% at depths between 1.5 and 2.5 m. Maxima in liquid water content for both lakes were coincident with layers of bubbles having arching morphologies which were predominantly associated with pockets of sedimentary material (silts, sand, and gravel). It is suggested that the majority (90%) of the liquid water in the ice is generated when visible radiation is absorbed by lithogenic matter within the ice during the austral summer. (Auth. mod.)

The evaluations support the following suggestions: (a) The mean annual runoff of all models follows, at least generally, the strong climatic East-West gradient of precipitation, although most models predict too much runoff in the dry part of the basin. (b) The mean monthly storage change tends to be underestimated, even though all models capture reasonably well the seasonality of the evapotranspiration. (c) The wide range of conceptualizations used for generation of surface and subsurface runoff strongly affect runoff generation on seasonal, and shorter, time scales. Model responses to summer precipitation ranged from almost no summer runoff (one model) to the (more common) situation of persistent overprediction of summer runoff, especially in the driest part of the basin. (d) All models tended to underpredict evapotranspiration in summer and overpredict in winter. (e) Model-derived mean seasonal cycles of changes in soil moisture storage are qualitatively similar to those inferred from observations, but most models do not predict the decrease in April soil moisture storage and the increase in October that is inferred from observations.

Comparisons of simulated surface energy fluxes among models showed that the net radiation and surface temperature generally had the best agreement among the schemes. On an average (annual and monthly) basis, the estimated latent heat fluxes agreed (to within approximate estimation errors) with the latent heat fluxes derived from a radiosonde-based atmospheric budget method for slightly more than half of the schemes. The sensible heat fluxes had larger differences among the schemes than did the latent heat fluxes, and the model-simulated ground heat fluxes had large variations among the schemes. The spatial patterns of the model-computed net radiation and surface temperature were generally similar among the schemes, and appear reasonable and consistent with observations of related variables, such as surface air temperature. The spatial mean patterns of latent and sensible heat fluxes were less similar than for net radiation, and the spatial patterns of the ground heat flux vary greatly among the 16 schemes. Generally, there is less similarity among the models in the temporal (interannual) variability of surface fluxes and temperature than there is in the mean fields, even for schemes with similar mean fields.

The objects have been classified and their abundances, size distributions, bulk compositions, and (where possible) plagioclase compositions determined. By number, 64% consist predominantly of very fine-grained equant plagioclase grains but can also contain larger ( approximately 50 mu m) feldspar crystals (type X), while 22% contain plagioclase lathes in a fine-grained mafic mesostasis (type Y). Plagioclase in both spherule types displays bright yellow cathodoluminescence that is conspicuous among the blue CL of the normal feldspar of the breccias. Type Z spherules (5%) contain feldspar with blue CL and minor amounts of olivine and pyroxene. Type Q spherules (4%) contain feldspar with yellow CL but in a luminescent mesostasis (of quartz or feldspar?). A few spherules are mixtures of type Y and type X textures. Most type X spherules, and a few type Y spherules, have fine-grained opaque rims. Compound objects were also found and consist of two or more CLS that appear to have collided while still plastic or molten. The CLS are thought to be impact spherules that crystallized in free flight, their coarse textures suggesting fairly slow cooling rates ( approximately <1 degrees C/s). The abundance of the CLS resembles that of chondrules in the CM chondrite Murchison, and their cumulative size-frequency distributions are very similar to those of the chondrules in several meteorite classes. The bulk compositions of the CLS do not resemble regoliths at any of the Apollo sites, including Apollo 14, or any of the common impact glasses, but they do resemble the bulk compositions of several lunar meteorites and the impact glasses they contain. The Apollo 14 site is located on a region containing Imbrium ejecta, and we suggest that the CLS derive from the Imbrium impact. Ballistic calculations indicate that only impact events of this size on the Moon are capable of producing melt spherules with the required free flight times and slow cooling rates. Smaller impacts produce glassy spherules and agglutinates. As has been pointed out many times, the CLS have many properties in common with meteoritic chondrules. While much remains unclear, difficulties with a nebular origin and new developments in chondrule chronology, studies of asteroid surfaces and the impact ejecta behavior, and the present observations indicate that meteoritic chondrules could have formed by impact.

Forcing data (precipitation, incoming radiation and surface meteorology) and land-surface characteristics (soil and vegetation parameters) were provided to each of the participating schemes. Two groups of runs are presented. (1) Calibration-validation runs, using data from six small catchments distributed across the modeling domain. These runs were designed to test the ability of the schemes to transfer information about model parameters to other catchments and to the computational grid boxes. (2) Base-runs, using data for 1979-1988, designed to evaluate the ability of the schemes to reproduce measured energy and water fluxes over multiple seasonal cycles across a climatically diverse, continental-scale basin. All schemes completed the base-runs but five schemes chose not to calibrate. Observational data (from 1980-1986) including daily river flows and monthly basin total evaporation estimated through an atmospheric budget analysis, were used to evaluate model performance. In general, the results are consistent with earlier PILPS experiments in terms of differences among models in predicted water and energy fluxes. The mean annual net radiation varied between 80 and 105 W m (super -2) (excluding one model). The mean annual Bowen ratio varied from 0.52 to 1.73 (also excluding one model) as compared to the data-estimated value of 0.92. The run-off ratios varied from a low of 0.02 to a high of 0.41, as compared to an observed value of 0.15. In general, those schemes that did not calibrate performed worse, not only on the validation catchments, but also at the scale of the entire modeling domain. This suggests that further PILPS experiments on the value of calibration need to be carried out.

Comparison of the SSM/I data to profiles obtained during the 1989-91 field seasons indicated that delta D and delta (super 18) O data from the near-surface snow at the Greenland summit are a reliable, high-resolution temperature proxy. To test this new technique further, additional stable-isotope data were obtained from a 2 m snow pit constructed during late-June 1995 near the GISP2 site. This new profile, supported by pit stratigraphy and chemistry data, confirms the utility of comparing stable-isotope records with SSM/I brightness temperatures. The sub-annual variation of the 6D record at the GISP2 site was determined using 15 match points, from approximately December 1991 through June 1995 and was guided in part by time-constrained hoar layers. The close association of these temperature proxies supports the assertion that snow accumulation occurs frequently through the year and that the isotope record initially contains temperature information from many times of the year. This is also independently confirmed by analysis of H (sub 2) O (sub 2) data. The slope of the multi-year T vs delta correlation was evaluated along with the sub-annual variation in the amount, rate and timing of accumulation. These new results are consistent with those from the previous study and they also demonstrate that the snow in this area initially contains temperature and chemical records with sub-annual resolution. This encourages confident interpretation of the paleoclimatic signal variations in the GISP2 and GRIP deep cores.

The relative population of meteorite types appears to be broadly compatible with the modern fall population, although there are minor differences. In particular, there are populations of small unusual irons, carbonaceous chondrites and lunar samples not found among the modern falls. In addition, slight compositional differences between modern and old (Antarctic) H chondrites may signal a time-dependent change in the flux to Earth of more common meteorites.

The work was stimulated, in part, by an atmospheric particle "sample of opportunity" collected at Summit, Greenland in August 1994, that bore the (super 14) C imprint of biomass burning. During the summer field seasons of 1995 and 1996, we collected air filter, surface snow and snowpit samples to investigate chemical and isotopic evidence of combustion particles that had been transported from distant fires. Among the chemical tracers employed for source identification are organic acids, potassium and ammonium ions, and elemental and organic components of carbonaceous particles. Ion chromatography, performed by members of the Climate Change Research Center (University of New Hampshire), has been especially valuable in indicating periods at Summit that were likely to have been affected by the long range transport of biomass burning aerosol. Univariate and multivariate patterns of the ion concentrations in the snow and ice pinpointed surface and snowpit samples for the direct analysis of particulate (soot) carbon and carbon isotopes. The research at NIST is focusing on graphitic and polycyclic aromatic carbon, which serve as almost certain indicators of fire, and measurements of carbon isotopes, especially (super 14) C, to distinguish fossil and biomass combustion sources. Complementing the chemical and isotopic record, are direct "visual" (satellite imagery) records and less direct backtrajectory records, to indicate geographic source regions and transport paths. In this paper we illustrate the unique way in which the synthesis of the chemical, isotopic, satellite and trajectory data enhances our ability to develop the recent history of the formation and transport of soot deposited in the polar snow and ice.

While the SLR data available from late-1992 onward are superior in satellite and temporal coverage (two station shifts in operation by the NASA Network), SLR data extending back to the mid-1970s have been utilized by some of the analysis centers. Two solutions for secular zonals and the SPACE'93 secular polar motion rates are evaluated to provide constraints on geophysical models describing post-glacial rebound (PGR) and ice sheet mass balance/sea level rise using an inverse method. The observed secular rate of global sea level change is also used as a constraint in various solutions. The benefits of forward modeling the water impoundment in reservoirs and the contributions of the mountain glaciers to the observed secular terms are discussed. Although the number of well resolved time dependent geopotential terms is limited, the inverse solutions are promising and provide results consistent with IPCC estimates of ice sheet mass balance and optimal estimates of mantle viscosity contrasts.

Two groups of mineralized springs occur near the McGill Field Station at Expedition Fiord. The first group is 3 km from the terminus of the White and Thompson Glaciers discharging at the base of the east side of Gypsum Hill adjacent to the floodplain of the Expedition River. The second site is at Colour Peak near the head of Expedition Fiord, approximately 10 km down valley from Gypsum Hill. Each spring group consists of 20-40 outlets spread over several hundred square metres. The mineralized nature of the discharge is responsible for a range of precipitates and travertine deposits. This paper documents spring discharge, water chemistry, and mineral precipitates associated with the springs.

Meteoroid streams produce meteor showers if a node of the stream is near 1 AU. On occasion, Earth encounters a stream of meteoroids that has not dispersed wide enough to be detected annually. A rare and often short lived enhancement of rates is observed during which the meteors typically have smaller radiant dispersion and sometimes anomalous fragmentation properties and end heights. Here, we summarize recent observations of these meteor outbursts and discuss how the results constrain our knowledge of the early stages of meteoroid stream formation. These stages tie meteoroid streams to cometary dust trails and are an important step in the dynamical evolution from cometary to zodiacal dust.

Such direct sampling of cosmic dust (or micrometeoroids, micrometeorites, interplanetary dust particles (IDP)) has enabled subsequent analyses of these extra-terrestrial micro particles at ground laboratories in great detail. In coming years, Japan will have an array of new opportunities of cosmic dust collection from space, stratosphere and Antarctica. However each collection site causes certain biases of samples in terms of physical and chemical alterations, selection effects and contamination. Here we review the cosmic dust collection from deep sea sediments, Greenland blue lakes, Antarctic ice cores, stratosphere and both near-Earth and interplanetary space, together with a brief description of the curation system of the samples being operated by NASA/JSC.

However, the use of simple "ratio type" estuarine flushing estimators generates estimates that are often inadequate and unverifiable. Obviously, estuarine flushing estimators that address more of the complexities of the flushing processes are needed. Difference equations lend themselves to modeling complex systems by virtue of their mathematical stability and ability to be linked into long complex inter-connecting series. With the above in mind, a simple to use model based on difference equations was developed for the explicit purpose of generating more realistic estuarine flushing estimates. The model and its application to a series of US Gulf of Mexico estuaries are presented in this paper. Estuarine oceanographers will recognize the relationships driving the model. However, an in-depth knowledge of estuarine oceanography is not required to understand or operate the model. Average estuary volume and average intertidal volume are used to drive the model as it tracks freshwater retention and flushing via tidal cycles. The configuration of the model accommodates vertically homogeneous and stratified salinity/flushing regimes. Application of the model to a series of U.S. Gulf of Mexico estuaries yields a 79% agreement between the model's freshwater input estimates and empirically derived freshwater input estimates. Linear regression analysis of the freshwater estimates of the model versus the empirically derived freshwater estimates, yields a r (super 2) of 0.98 for the estuaries modeled. The empirically derived freshwater estimates were used to approximate the salt-content of the estuaries as a check of their appropriateness for use in verifying the model. Comparison of the "empirically derived freshwater based salt-content approximations" versus "salt-content approximations based on the observed salinities of the estuaries" yields a 74% agreement, while linear regression yields a r (super 2) of 0.81 for the estuaries modeled. This generic model can be applied to estuaries with known low tide estuary volumes, intertidal volumes, and salinity characterizations. Electronic copies of the programming of the model are available from the author.

The ice sediment particles serve as nutrient (inorganic and organic)--enriched microzones for the establishment of a physiologically and ecologically complex microbial consortium capable of contemporaneous photosynthesis, nitrogen fixation, and decomposition. The consortium is capable of physically and chemically establishing and modifying a relatively nutrient- and organic matter- enriched microbial "oasis" embedded in the lake ice cover.

Along with the attributes familiar to researchers working with SAR data from the European Space Agency's Earth Remote Sensing Satellite and the Japanese Earth Resources Satellite, Radarsat-1 has enhanced flexibility to collect data using a variety of swath widths, incidence angles and resolutions. Most importantly, for scientists interested in Antarctica, Radarsat-1 can be maneuvered in orbit to rotate the normally right-looking SAR to left-looking mode. This 'Antarctic Mode' provides for the first time a nearly instantaneous, high-resolution view of the entirety of Antarctica on each of two proposed mappings separated by 2 years.

Although one cannot solve for both topography and ice motion using one interferometric pair, it is possible to use a coarsely sampled digital terrain model to estimate ice motion using an image registration method. Less accurate than the usual fringe counting method for estimation of radial displacement, the image registration method allows useful motion estimation in both range and azimuth. The method is described and some results shown for a large area ( approximately 17,000 km (super 2) ) including ice flow into the Filchner Ice Shelf.

The procedure used is as follows: 1.) Determine whether a purely MIR-based cloud detection scheme is possible over a snow-covered surface; 2.) Analyze the influence of changing vegetation type on the brightness temperatures; and 3.) Compare completely snow-covered scenes with partially snow-covered and snow-free regions for cloudy and clear sky periods to determine whether varying snow conditions affect the MIR data. Results show that the determination of cloudy pixels over a snow-covered surface is not possible using a simple brightness temperature threshold technique. Furthermore, it is concluded that while no statistical discrimination between specific vegetation classes can be made, statistical significance is obtained when the vegetation is grouped into two classes only, for example vegetated and barren. It is also shown that the state of the snow cover (complete coverage; melting; or patchy) has a distinct affect on these results.

In order to estimate the accuracy of the MODIS snow maps, the Northern Hemisphere was divided into 7 land-cover classes and water, and expected errors in mapping snow were calculated for each of the 7 classes using the average monthly snowline position. The errors are found primarily in land covers composed of forests. Maximum monthly snow-mapping errors are expected to range from 5-9% for North America, and from 5-10% for Eurasia. The largest errors are expected when snow coverage in the Boreal Forest is greatest. The maximum aggregated snow-mapping error for the Northern Hemisphere is expected to be about 7.5%. Error estimates will be refined after the first full year that MODIS data are available.

The purpose of this volume is to present new information about this ecosystem so that its role within the antarctic food-web (and as a sink for carbon dioxide) and its susceptibility to environmental changes can be better understood. Here are brought together articles covering a wide array of topics relating to sea ice biology and ecology. Four chapters present new information on algal biomass in sea ice. New physiological data is presented, including a chapter on nitrogen metabolism, as well as some topical aspects of sea ice microalgal physiology and their production of dimethylsulfoniopropionate. Two highly interdisciplinary chapters present results of numerical ecosystem modeling studies, one being at a small scale but highly mechanistic and the other being of a much larger scale but more highly parameterized. The eventual fate of sea ice algae is well documented in two chapters on zooplankton grazing and one on sedimentation and the use of sea ice diatoms as paleoenvironmental indicators.

The most common species in congelation ice are large pennates that, due to dissolution and dilution, rarely are found in sediments in abundances high enough to serve as sea ice proxies. However, the success of Fragilariopsis curta and F. cylindrus in exploiting both the sea ice and ice edge ecosystems results in a discrete record at the sea floor. In contrast, Thalassiosira antarctica and F. kerguelensis dominate regions of open water primary production in the southern ocean. Combined with data on the previous two species, sea ice distribution on the antarctic continental shelf can be evaluated. More subtle details of sea ice distribution probably can be reconstructed once researchers develop a more complete database on several fronts. Differences in the distribution of F. curta and F. cylindrus in both the water column and in sediments have been noted and should be explored. (Auth. mod.)

Analysis of satellite data indicates that the summer minimum extents (and area) in the Weddell Sea were highly variable from 1979 through 1995, but the correlations of summer ice characteristics to those of subsequent winter are generally weak. Wind effects appear to be an important factor in causing the large variability observed in the ice cover while the effects of air temperature variations are not apparent. Temporal variability of AABW in the western Weddell Sea from 1963 through 1993 also is observed, with the bottom water salinity being significantly lower in 1992 and 1993 than those in earlier decades.

Also determines entity-specific models using data subsets for conterminous grounded-ice and ice-shelf areas. Inversions of specific models produces two contoured distributions of ratio, one based on field data, other on remotely sensed data. Difference between these produces residuals that are small in interior area of ice sheet, large in several areas of mountain and coastal regions.

Results suggest that it is possible to scale from point measurements of environmental state variables to regional estimates of water and energy exchange. This research characterizes the unifying thread in the classical climate-topography-soil-vegetation relation--the surface water and energy balance--through maps of the partitioning of energy throughout the landscape. The study was conducted in Goshute Valley of northeastern Nevada, which is characteristic of most faulted graben valleys of the Basin and Range Province of the western United States. The valley comprises a central playa and lake plain bordered by alluvial fans emanating from the surrounding mountains. The distribution of evapotranspiration (ET) is lowest in the middle reaches of the fans where the water table is deep and plants are small, resulting in low evaporation and transpiration. Highest ET occurs in the center of the valley, particularly in the playa, where limited to no vegetation occurs, but evaporation is relatively high because of a shallow water table and silty clay soil capable of large capillary movement. Intermediate values of ET are associated with large shrubs and is dominated by transpiration.

Basaltic asteroids with radii of about 6 m take on the average 185 million years (Myr) for their semimajor axes to shrink by 0.52 AU, assuming circular orbits and ignoring planetary perturbations and collisions. All other sizes take longer. Bigger objects are slower because they are more massive, and smaller objects are slower because they are more isothermal. These results are based on treating the asteroids as spheres and solving the heat conduction equation using spherical Bessel functions. The small near-Earth asteroids show a concentration of sizes in the thermal drag range; thus some of them may come from Mars as survivors of gravitational mechanisms which eliminate them on the 10 Myr timescale. The possible role of thermal drag in Mars-Earth delivery will remain speculative until it is included in numerical integrations of the orbits of small asteroids.

The linear and non-linear state space models make accurate short-term predictions of the ozone dynamics. The average prediction error one hour in advance is 7 ig/m3 and increases logarithmically with time until it reaches 26 ig/m3 after 30 days. For a given sequence of solar radiation inputs, predictions converge exponentially with a time scale of 8 hours, so that the model is insensitive to perturbations of more than 150 ig/m3 03. The slow increase of the prediction error in addition to the uniqueness of the prediction are encouraging for applications of state space models in forecasting ozone levels when coupled with a model that predicts total radiation. Since a radiation prediction model will be more accurate during cloud-free conditions, in addition to the fact that the state space models perform better during the summer months, state space models are suitable for applications in sunny environments.

N1 - Last updated - 2014-05-07 ER - TY - RPRT T1 - Land Surface Temperature Measurements from EOD MODIS Data AN - 18333092; 4467080 AB - We made more tests of the version 2.0 daily Level 2 and Level 3 Land-Surface Temperature (LST) code (PGE 16) jointly with the MODIS Science Data Support Team (SDST). After making minor changes a few times, the PGE16 code has been successfully integrated and tested by MODIS SDST, and recently has passed the inspection at the Goddard Distributed Active Archive Center (DAAC). We conducted a field campaign in the area of Mono Lake, California on March 10, 1998, in order to validate the MODIS LST algorithm in cold and dry conditions. Two MODIS Airborne Simulator (MAS) flights were completed during the field campaign, one before noon, and another around 10 pm PST. The weather condition for the daytime flight was perfect: clear sky, the column water vapor measured by radiosonde around 0.3 cm, and wind speed less than a half meter per second. The quality of MAS data is good for both day and night flights. We analyzed the noise equivalent temperature difference (NE(delta)T) and the calibration accuracy of the seven MAS thermal infrared (TIR) bands, that are used in the MODIS day/night LST algorithm, with daytime MAS data over four flat homogeneous study areas: two on Grant Lake (covered with ice and snow, respectively), one on Mono Lake, and another on the snow field site where we made field measurements. NE(delta)T ranges from 0.2 to 0.6 k for bands 42, 45, 46, and 48. It ranges from 0.8 to 1.1 K for bands 30-32. The day and night MAS data have been used to retrieve surface temperature and emissivities in these bands. A simple method to correct the effect of night thin cirrus has been incorporated into the day/night LST algorithm in dry atmospheric conditions. We compared the retrieved surface temperatures with those measured with TIR spectrometer, radiometers and thermistors in the snow test site, and the retrieved emissivity images with topographic map. retrieved from MAS data is 3.3 K colder than those from field measurements most likely because of the effect of haze at night. The good agreement among the regional averaged surface temperatures obtained from LST values retrieved at different resolutions increased our confidence in the MODIS day/night LST algorithm.

In this project, we combined product generation, observational analyses, and modeling to define and interpret variability in ice motion in conjunction with thermodynamic factors such as surface temperature and albedo. The goals of this work were twofold: (1) to develop and test procedures to produce an integrated set of polar products from remotely-sensed and supporting data; and (2) to apply these data to understand processes at work in controlling sea ice distribution.

The seasonal cycle characteristics remain essentially the same as for the shorter time series, but the local trends are markedly different, in some cases reversing sign. The sign reversal reflects the lack of a consistent long-term trend and could be the result of localized long-term oscillations in the hemispheric sea ice covers. By combining the separate hemispheric sea ice records into a global one, we have shown that there are statistically significant net decreases in the sea ice coverage on a global scale. The change in the global sea ice extent, is -0.01 +/- 0.003 x 10(exp 6) sq km per decade. The decrease in the areal coverage of the sea ice is only slightly smaller, so that the difference in the two, the open water within the packs, has no statistically significant change.

N1 - Last updated - 2014-05-07 ER - TY - RPRT T1 - Total Lightning and Radar Storm Characteristics Associated with Severe Storms in Central Florida AN - 18331544; 4467774 AB - A number of prior studies have examined the association of lightning activity with the occurrence of severe weather and tornadoes, in particular. High flash rates are often observed in tornadic storms (Taylor, 1973; Johnson, 1980; Goodman and Knupp, 1993) but not always. Taylor found that 23% of nontornadic storms and 1% of non-severe storms had sferics rates comparable to the tornadic storms. MacGorman (1993) found that storms with mesocyclones produced more frequent intracloud (IC) lightning than cloud-to-ground (CG) lightning. MacGorman (1993) and others suggest that the lightning activity accompanying tomadic storms will be dominated by intracloud lightning-with an increase in intracloud and total flash rates as the updraft increases in depth, size, and velocity. In a recent study, Perez et al. (1998) found that CG flash rates alone are too variable to be a useful predictor of (F4, F5) tornado formation. Studies of non-tomadic storms have also shown that total lightning flash rates track the updraft, with rates increasing as the updraft intensities and decreasing rapidly with cessation of vertical growth or downburst onset (Goodman et al., 1988; Williams et al., 1989). Such relationships result from the development of mixed phase precipitation and increased hydrometer collisions that lead to the efficient separation of charge. Correlations between updraft strength and other variables such as cloud-top height, cloud water mass, and hail size have also been observed.

As part of an effort to address the latter issue, a biofilm system was developed by Marshall Space Flight Center (MSFC) to simulate the conditions aboard ISS with respect to materials, flow rates, water conditions, water content, and handling. The tubing, connectors, sensors, and fabricated parts included in the system were chosen for specific attributes as applicable to emulate an orbital water treatment system. This paper addresses the design and development process of the system, as well as the configuration, operation, and system procedures for maintenance to assure that the simulation is valid for the representative data as it applies to water degradation and biofilm /microbial growth. Preliminary biofilm/microbial results are also presented.

The model solves the global primitive equations in isentropic coordinates, which directly characterize diabatic processes forcing the Brewer-Dobson circulation of the middle atmosphere. Its numerical formulation is based on Hough harmonics, which partition horizontal motion into its rotational and divergent components. These computational features, along with others, enable 3D integrations to be performed practically on RISC computer architecture, on which they can be iterated to support mechanistic studies. The model conserves potential vorticity quite accurately under adiabatic conditions. Forced by observed tropospheric structure, in which integrations are anchored, the model generates a diabatic circulation that is consistent with satellite observations of tracer behavior and diabatic cooling rates. The model includes a basic but fairly complete treatment of gas-phase photochemistry that represents some 20 chemical species and 50 governing reactions with diurnally- varying shortwave absorption. The model thus provides a reliable framework to study transport and underlying diabatic processes, which can then be compared against chemical and dynamical structure observed and in GCM integrations. Integrations with the Langley GCM were performed to diagnose feedback between simulated convection and the tropical circulation. These were studied in relation to tropospheric properties controlling moisture convergence and environmental conditions supporting deep convection, for comparison against mechanistic integrations of wave CISK that successfully reproduce the Madden-Julian Oscillation (MJO) of the tropical circulation. These comparisons were aimed at identifying and ultimately improving aspects of the convective simulation, with the objective of recovering a successful simulation of the MJO in the Langley GCM, behavior that should be important to budgets of upper-tropospheric water vapor and chemical species.

N1 - Last updated - 2015-03-24 ER - TY - RPRT T1 - Sources of Methane in the Boreal Region AN - 17661275; 4467071 AB - In determining the global methane budget the sources of methane must be balanced with the sinks and atmospheric inventory. The approximate contribution of the different methane sources to the budget has been establish showing the major terrestrial inputs as rice, wetlands, bogs, fens, and tundra. Measurements and modeling of production in these sources suggest that temperature, water table height and saturation along with substratum composition are important in controlling methane production and emission. The isotopic budget of 13 C and D/H in methane can be used as a tool to clarify the global budget. This approach has achieved success at constraining the inputs. Studies using the isotopic approach place constraints on global methane production from different sources. Also, the relation between the two biogenic production pathways, acetate fermentation and CO2 reduction, and the effect of substratum composition can be made using isotope measurements shows the relation between the different biogenic, thermogenic and anthropogenic sources of methane as a function of the carbon and hydrogen isotope values for each source and the atmosphere, tropospheric composition. Methane emissions from ponds and fens are a significant source in the methane budget of the boreal region. An initial study in 1993 and 1994 on the isotopic composition of this methane source and the isotopic composition in relation to oxidation of methane at the sediment surface of the ponds or fen was conducted as part of our BOREAS project. The isotopic composition of methane emitted by saturated anoxic sediment is dependent on the sediment composition and geochemistry, but will be influenced by in situ oxidation, in part, a function of rooted plant activity. The influence of oxidation mediated by rooted plant activities on the isotopic composition of methane is not well known and will depend on the plant type, sediment temperature, and numerous other variables. Information on this isotopic composition is important in both understanding the bio- geochemistry of the system and also in determining the regional and global inputs for the methane isotope budget. In determining the destruction of methane for balancing the atmospheric methane budget soil oxidation must be considered.

This flight program was a joint effort between the National Aeronautics and Space Administration (NASA), the National Center for Atmospheric Research (NCAR), and the Federal Aviation Administration (FAA). Based on weather forecasts and real-time in-flight guidance provided by NCAR, the NASA-Lewis Icing Research Aircraft was flown to locations where conditions were believed to be conducive to the formation of Supercooled Large Droplets aloft. Onboard instrumentation was then used to record meteorological, ice accretion, and aero- performance characteristics encountered during the flight. A total of 29 icing research flights were conducted, during which 'conventional' small droplet icing, SLD, and mixed phase conditions were encountered aloft. This paper will describe how flight operations were conducted, provide an operational summary of the flights, present selected experimental results from one typical research flight, and conclude with practical 'lessons learned' from this first year of operation.

The tenuous clouds and sparse particulate matter in the relatively particle-free 5-micron 'hot spot' region of the Probe's descent were documented from about 0.46 bars to about 12 bars. Three regions of apparent coherent structure were noted, in addition to many indications of extremely small particle concentrations along the descent path. From the first valid measurement at about 0.46 bars down to about 0.55 bars a feeble decaying lower portion of a cloud, corresponding with the predicted ammonia particle cloud, was encountered. A denser, but still very modest, particle structure was present in the pressure regime extending from about 0.76 to a distinctive base at 1.34 bars, and is compatible with the expected ammonium hydrosulfide cloud. No massive water cloud was encountered, although below the second structure, a small, vertically thin layer at about 1.65 bars may be detached from the cloud above, but may also be water condensation, compatible with reported measurements of water abundance from other Galileo Mission experiments. A third small signal region, extending from about 1.9 to 4.5 bars, exhibited quite weak but still distinctive structure, and, although the identification of the light scatterers in this region is uncertain, may also be a water cloud perhaps associated with lateral atmospheric motion and/or reduced to a small mass density by atmospheric subsidence or other explanations. Rough descriptions of the particle size distributions and cloud properties in these regions have been derived, although they may be imprecise because of the small signals and experimental difficulties. These descriptions document the small number densities of particles, the moderate particle sizes, generally in the slightly submicron to few micron range, and the resulting small optical depths, mass densities due to particles, column particle number loading and column mass loading in the atmosphere encountered by the Galileo Probe during its descent.

Uncertainty descriptions are updated at test points to account for unmodeled time-varying dynamics of the airplane by ensuring the robust model is not invalidated by measured flight data. Robust margins computed with respect to this uncertainty remain conservative to the changing dynamics throughout the flight. A simulation clearly demonstrates this method can improve the efficiency of flight testing by accurately predicting the flutter margin to improve safety while reducing the necessary flight time.

N1 - Last updated - 2011-12-13 ER - TY - RPRT T1 - LDAR, A Three-Dimensional Lightning Warning System: Its Development and Use by the Government, and Transition to Public Availability AN - 17575337; 4464298 AB - NASA, at the John F. Kennedy Space Center (KSC), developed and operates a unique high precision lightning location system to provide lightning related weather warnings. These warnings are used to stop lightning-sensitive operations such as space vehicle launches and ground operations where equipment and personnel are at risk. The data is provided to the Range Weather Operations (45th Weather Squadron, U. S. Air Force (USAF)) where it is used with other meteorological data to issue weather advisories and warnings for Cape Canaveral Air Station (CCAS) and KSC operations. This system, called Lightning Detection and Ranging (LDAR), provides users with a graphical display in three dimensions of 66 MHz radio frequency events generated by lightning processes. The locations of these events provide a sound basis for the prediction of lightning hazards. NASA and Global Atmospherics, Inc. are developing a new system that will replace the unique LDAR components with commercially available and maintainable components having improved capabilities. These components will be phased in to ensure full continuity and access to this important warning technology. These LDAR systems are expected to eventually be available for installation and use by the public at specialized facilities, such as airports, and for general weather warnings via the National Weather Service (NWS) or television broadcast. The NWS in Melbourne has had access to real-time LDAR data since 1993 on an experimental basis. This use of LDAR has shown promise for the improvement of aviation forecasts and severe weather warnings. More so, it has opened the door to investigate the feasibility of issuing lightning-related public advisories. The success of its early use suggests that this technology may improve safety and potentially save lives, therefore constituting a significant benefit to the public. This paper describes the LDR system, the plans and progress of these upgrades, and the potential benefits of its use.

N1 - Last updated - 2011-12-13 ER - TY - JOUR T1 - Alpine glacial geomorphological studies in the central Andes using Landsat Thematic Mapper images AN - 17401740; 4632451 AB - Satellite images are a powerful tool for geomorphological studies, but have been used far less than aerial photography. In particular, the regional overview provided by Landsat Thematic Mapper (TM) images has been found to be extremely valuable for studying Late Pleistocene glaciation in the central Andes. Standard image processing techniques were used to create a Landsat Thematic Mapper (TM) mosaic of the central Andes suitable for a variety of geomorphological studies. The mosaic was used to map the extent of Late Pleistocene glaciation from the extent of well-preserved terminal moraines and other glacial geomorphological features. Moraines in many portions of the central Andes are unusually well preserved due to the region's semiarid to arid environment. Using a scaling relationship between glacier area and volume, the ice volumes of both Late Pleistocene and modern glaciers in the central Andes were estimated. The total volume of the region's palaeo-glaciers is estimated to be 3700 km super(3). The modern total is estimated to be only one percent of this volume or approximately 35-53 km super(3).

With the use of a discrete-ordinate radiative-transfer model, the relative contributions of hoar and accumulation to microwave emission are examined. The results show that the link between microwave emission and accumulation rates in the dry-snow area of the Greenland ice sheet is significant; however, the emissivity is also dependent on the extent of hoar development. As a result, accumulation estimates based on passive microwave observations in the low-accumulation dry-snow areas will require successful parameterization of hoar formation. Furthermore, the increasing T sub(b) trends that were observed during the 1980s, which have been hypothesized to be related to accumulation changes, may be strongly related to variations in hoar development. Other possible explanations for these observed trends, such as slight surface melt or atmospheric conditions, are also discussed.

To accomplish this goal, it is necessary to pursue the development of thermal and mechanical durability models for graphite fiber reinforced, polymer matrix composites. Numerous investigations have been reported regarding the thermo-oxidative stability (TOS) of the polyimide PMR-15. It is yet to be determined if the information obtained from the PMR-15 composite tests is applicable to other polymer matrix composites. The condensation curing polymer Avimid N is another advanced composite material often considered for structural applications at high temperatures. Avimid N is reported to have better thermo-oxidative stability (TOS) than PMR-15, but the latter is more easily processed. The purposes of the work described herein one to compare the thermal aging behavior of these two matrix polymers and to determine the reasons for and the consequences of differences in thermal durability. Differences were observed in weight loss time data, microstructural changes, and compression properties after aging at temperatures of 204, 260, 288, 316, and 343 degree C. Of special interest were the differences in surface thermal and oxidative damage, and also the extent of internal cracking.

A HSI map was derived using a HSI model, vegetation, and fire patterns that were mapped from aerial imagery. Family size, reproductive success, and survival data were collected at nests and territories between 1988 and 1993 using colorbanded jays. The ability to predict demographic performance (potential-breeder production minus breeder mortality) using the HSI model was tested at patch (0.1 and 1.0 ha) and territory (5.5 ha) scales. Florida scrub-jays preferred to nest in patches having the highest HSI and had the highest fledgling production in patches with the highest HSI. Yearling production, breeder survival, jay density, and demographic performance were all correlated with HSI. Minor improvements in the ability to predict demographic performance occurred as sampling scale increased from the smallest patch (0.1 ha) to the territory scale (5.5 ha). Population sources (potential-breeder production exceeded breeder mortality) comprised 28% of the habitat within the study site and had inadequate demographic performance to sustain population sinks (breeder mortality exceeded potential-breeder production), which comprised 62% of the habitat. Jay densities were not indicators of demographic performance.

We report on data obtained during the first four orbits about Jupiter that had flybys of the Galilean satellites: Ganymede (orbits 1 and 2), Callisto (orbit 3), and Europa (orbit 4). The most prominent features observed are highly time variable dust streams recorded throughout the Jovian system. The impact rate varied by up to 2 orders of magnitude with a 5 and 10 hour periodicity, which shows a correlation with Galileo's position relative to the Jovian magnetic field. Around 20 R (sub J) (Jupiter radius, R (sub J) = 71,492 km) in bound a dip in the impact rate has been found consistently. At the same times, reversals by 180 degrees in impact direction occurred. This behavior can be qualitatively explained by strong coupling of nanometer-sized dust to the Jovian magnetic field. At times of satellite flybys, enhanced rates of dust impacts have been observed, which suggests that all Galilean satellites are sources of ejecta particles. Inside about 20 R (sub J) impacts of micrometer-sized particles have been recorded that could be particles on bound orbits about Jupiter.

In this paper, we present case studies on two major coastal oil spills, which have been captured by the remote sensing imagery. The detection and tracking of the oil slicks are achieved by means of two-dimensional Gaussian-based wavelet analysis.

In this paper we begin to put these phenomena together to examine their interrelationships and to estimate the extent to which upwelling enhances productivity along that part of the west coast of North America where it is prominent for a season. Accordingly, the long-term temporal and spatial features of upwelling in ocean waters along the west coast are summarized. In regions of particularly strong upwelling, illustrative ocean observations, measurements, and computations are performed at selected locations spanning more than a decade in time. Results are compared with the results of other studies. Upwelling is shown to enrich biomass as much as fiftyfold. An analytic solution to an approximate set of the rigorous coupled hydrodynamic, energy, radiative transfer, and species conservation equations is presented and described. This includes the effects of weather, wind induced shear stress and its variation (which affect the upwelling formation), illumination (which affects the production of a biomass in surface waters), solar heating, and other physical, chemical, photochemical, and biological events in coastal waters. An approximate analogy (or index) which relates local sea surface temperature and primary productivity parameters in the upwelling formation is discussed. Computed results are compared to NOAA coastal ocean observations.

AN - 16549906; 4382845 AB - Phytoplankton are a major source of marine primary productivity. Factors that control algal productivity range from the physical to the chemical to the biological. Currently, levels of atmospheric carbon dioxide and surficial fluxes of ultraviolet radiation are rising. Both of these environmental variables can have a profound effect on algal productivity. Atmospheric CO sub(2) may increase levels of dissolved inorganic carbon in the ocean surface. Laboratory and field studies of algal mats and phytoplankton cultures under ambient and elevated levels of pCO sub(2) show that elevated levels of inorganic carbon can cause an increase in photosynthetic rates. The increase in photosynthetic rates can result in higher population density. There may be an increase in the excretion of fixed carbon, which in turn may enhance bacterial productivity. Alternatively, in analogy with studies on the effect of elevated pCO sub(2) on plants, the phytoplankton could change their carbon to nitrogen ratios, which will affect the feeding of the planktonic grazers. The seasonal depletion of stratospheric ozone has resulted in elevated fluxes of UVB radiation superimposed on the normal seasonal variation. Present surface UV fluxes have a significant direct impact on algal photosynthesis, as well as indirect effects on cell physiology and aquatic chemistry. While not disputing the importance of other factors in controlling marine phytoplankton productivity, it is argued here that the global change variables of elevated pCO sub(2) and UVB radiation should not be ignored.

Some environmental variables that have a profound biological effect are changing; for example, surficial fluxes of UVB radiation are rising. What is not known for aquatic systems is the natural annual variability in the effect of UV radiation on plankton. An exciting opportunity to obtain these data has recently become available. The Marine Sciences Institute (MSI) of Redwood City, a science educational organization that runs educational cruises for teachers and students, has begun a collaboration with NASA/Ames to monitor annual variability in UV radiation and its effect on the biota of the San Francisco Bay Estuary. The students and teachers at MSI obtain weekly samples of surface water, make basic physical and chemical measurements of key environmental parameters, and survey fish. High school and college students based at NASA/Ames collect the samples from MSI and take them to NASA for analysis of UV-absorbing pigments and biomass. We have hypothesized that phytoplankton will produce UV-absorbing pigments in direct response to surficial fluxes of UV radiation, and the early results appear to support the hypothesis. Additional components will be added to this project in the coming year, including analyses of UV-induced DNA damage in the plankton and the acquisition of remotely-sensed data. The educational value of this work will be enhanced through the formation of a Web Site with some data along with information from NASA researchers to assist participating students and teachers in analyzing and interpreting their data, and anyone worldwide in using this study as a classroom exercise. The total data set will be published in the scientific literature. The result will be a critical environmental study on annual variation within this important aquatic community that could not be done without the student contribution.

The analysis employs a finite element method and includes unsteady aerodynamic effects (dynamic stall) and a nonuniform inflow model. The stall suppression system, based on a transfer matrix approach, uses blade root actuation to suppress stall directly. The results show that stall can effectively be suppressed using higher harmonic blade root pitch at both cruise and high-speed flight conditions. The control amplitude was small, less than 1 deg. In a high-thrust, low-speed flight condition, stall is fairly insensitive to higher harmonic inputs. In general, stall suppression does not guarantee performance improvements. The results also show the distinction between stall suppression and performance improvement with active control. When the controller aims to reduce the shaft torque, rotor performance improvement can be achieved with a small degradation in stall behavior.

A two-layer model for solving energy and water balance is presented. The vertical soil column between the soil surface and the water table is divided into the root zone and the transmission zone. The variable infiltration capacity (VIC) concept is used to introduce a spatially varied distribution of soil moisture in the root zone layer. The soil moisture is distributed uniformly in space in the transmission zone layer. The model is used to simulate the fluxes for the King's Creek catchment in Manhattan, Kansas for a period between June through October 1987 (for the four intensive field campaigns), during which the first ISLSCP (International Satellite Land Surface Climatology Project) field experiment (FIFE) was conducted. The model is calibrated using the observed data during the first intensive field campaign (IFC) and validated over the next three IFCS. The energy and water balance equations are solved to yield the time series of fluxes which are compared to their observed counterparts. The model predicted diurnal variation of the evaporative fluxes and the variation of the fluxes after rainfall events is compared with the observations. The model computed fluxes match fairly well with the observed fluxes. JF - Journal of Hydrology (Amsterdam) AU - Lakshmi, V AU - Wood, E F AD - Gen. Sci.

The mission was to penetrate the exhaust plumes and/or contrails of other subsonic jet aircraft and determine the concentrations of submicrometer diameter aerosol particles. Mission criteria required rapid response measurements ( similar to 1 s) at aircraft cruise altitudes (9-12 km). The CNC sampling system was optimized to operate at 160 Torr. Aerosol samples were acquired through an externally mounted probe. Installed downstream of the probe was a critical flow orifice that provided sample to the CNC system. The orifice not only controlled volumetric flow rate, but also dampened probe pressure/flow oscillations encountered in the turbulent aircraft-wake vortex environment. Laboratory calibrations with NaCl particles under representative conditions are reported that indicate small amounts of particle loss and a maximum measurement efficiency of similar to 75% for particles with diameters ranging from greater than or equal to 0.01- less than or equal to 0.18 mu m. Data from exhaust/contrail samplings of a NASA B757 and DC-8 at cruise altitude are discussed. Data include exhaust/contrail measurements made during periods in which the B757 port jet engine burned low-sulfur fuel while the starboard engine simultaneously burned specially prepared high-sulfur fuel. The data discussed highlight the CNC systems performance, and introduce new observations pertinent to the behavior of sulfur in aircraft exhaust aerosol chemistry.

The tools required to implement such an approach are discussed. These involve the use of global velocimetry to measure those Lighthill turbulent stress tensor terms thought most important to noise generation. The framework of the dynamic systems model as it applies to the development of a noise suppression model is discussed, as well as the latest results on the development of an actuator for control input. The dynamic systems model offers a unique opportunity to study the influence of a concept noise reduction scheme on noise reduction through appropriate algorithms that relate turbulent jet processes to noise.

The analysis shows (among other things) how the stretching of the vortex lines around the plate leads to streamwise vorticity at the plate surface, which then produces a streamwise velocity perturbation within the boundary layer that can be related to the experimentally observed Klebanoff mode. The complete evolution of this flow must be found by solving the boundary-region equations of Kemp (1951) and Davis and Rubin (1980), but a limiting analytical solution can also be obtained. Since the initial growth of the boundary-layer disturbance is nearly algebraic, our results demonstrate how the algebraically growing disturbances promoted by Landahl and others can be generated by a realistic external-disturbance environment. The relationship between these results and various bypass transition mechanisms is discussed.

The idea behind the acoustic analogy is simple but powerful. The entire noise generation process is mathematically reduced to the study of wave propagation in a quiescent medium with the effect of flow replaced by quadrupole sources. In jet noise theory, Lighthill was able to obtain significant and useful qualitative results from the acoustic analogy. The acoustic analogy has influenced the theoretical and experimental research on jet noise since the early 1950s. This paper, however, focuses on another area in which the acoustic analogy has had a significant impact, namely, the prediction of the noise of rotating machinery. The governing equation for this problem was derived by Ffowcs Williams and Hawkings in 1969. This equation is a wave equation for perturbation density with three source terms, which have become known as thickness, loading, and the quadrupole source terms, respectively. The Ffowcs Williams-Hawkings (FW-H) equation has been used for the successful prediction of the noise of helicopter rotors, propellers, and fans. Several reasons account for the success and popularity of the acoustic analogy. First, the problems of acoustics and aerodynamics are separated. Second, because the FW-H equation is linear, powerful analytical methods from linear operator theory can be used to obtain closed-form solutions. Third, advances in digital computers and computational fluid dynamics algorithms have resulted in high-resolution near-field aerodynamic calculations that are suitable for noise prediction. We present some of the mathematical results for noise prediction based on the FW-H equation, including examples for helicopter rotors. In particular, we discuss the prediction of blade-vortex interaction noise and high-speed impulsive noise of helicopter rotors. For high-speed propellers, we briefly discuss the derivation of a singularity-free solution of the FW-H equation for a supersonic panel on a blade.
