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.
