AN - 72427773; 11086666 AB - The National Aeronautics and Space Administration (NASA) has used iodination as a method of microbial disinfection of potable water systems in U.S. spacecraft and long-duration habitability modules. A review of thyroid function tests of NASA astronauts who had consumed iodinated water during spaceflight was conducted. Thyroid function tests of all past and present astronauts were reviewed. Medical records of astronauts with a diagnosis of thyroid disease were reviewed. Iodine consumption by space crews from water and food was determined. Serum thyroid-stimulating hormone (TSH) and urinary iodine excretion from space crews were measured following modification of the Space Shuttle potable water system to remove most of the iodine. Mean TSH significantly increased in 134 astronauts who had consumed iodinated water during spaceflight. Serum TSH, and urine iodine levels of Space Shuttle crewmembers who flew following modification of the potable water supply system to remove iodine did not show a statistically significant change. There was no evidence supporting association between clinical thyroid disease and the number of spaceflights, amount of iodine consumed, or duration of iodine exposure. It is suggested that pharmacological doses of iodine consumed by astronauts transiently decrease thyroid function, as reflected by elevated serum TSH values. Although adverse effects of excess iodine consumption in susceptible individuals are well documented, exposure to high doses of iodine during spaceflight did not result in a statistically significant increase in long-term thyroid disease in the astronaut population.

AN - 72425209; 11086665 AB - Dietary salt is known to increase the excretion of urinary calcium (Ca). To determine the potential role of dietary sodium (Na) on the calciuria associated with a spaceflight simulation model, we evaluated urinary Ca in two groups of bed rest subjects fed either high or low normal amounts of salt. We analyzed urinary Ca excretion expressed in terms of creatinine (UCa/Cr), fractional Ca excretion (FECa), and urinary cAMP (UCAMP) as an index of parathyroid function, in the urine of 30-50-yr-old male volunteers for 6 degrees head down tilt bed rest studies. Dietary Na was in the high normal range (190 mmol x d(-1)) in 8 men for 7 d (HiNa), and in the low normal range (114 mmol x d(-1)) in 11 men for 30 d (LoNa) bed rest. Dietary Ca averaged 20 mmol x d(-1) in both studies. Within the first 3 bed rest days, subjects in the HiNa study showed increases in UCa/Cr (0.1130 +/- 0.05 to 0.161 +/- 0.05, p < 0.002) and in FECa (1.95 +/- 0.70 to 3.19 +/- 0.93, p < 0.001); those in LoNa showed no change in UCa/Cr (0.125 +/- 0.06 to 0.121 +/- 0.07, NS) or FECa (1.93 +/- 0.75 to 2.22 +/- 0.63). After the 5th bed rest day UCa/Cr stabilized at similar levels in both dietary groups. UCAMP decreased 20% during the first week of bed rest with HiNa, but not until the third week with LoNa diets (p < 0.05). These findings implicate high salt diets in Ca excretion in a spaceflight model and suggest that low normal salt diets may reduce early calciuria associated with spaceflight.

Three different personality types for captains were classified based on a previous cluster analysis. Crews were comprised of three crewmembers: captain, first officer, and second officer/flight engineer. A total of 72 pilots completed a 1.5-d full-mission simulation of airline operations including emergency situations in the Ames Manned Vehicle System Research Facility B-727 simulator. Crewmembers were tested for perceived stress on four dimensions of the NASA Task Load Index after each of five flight legs. Crews were divided into three groups based on rankings from combined error and rating scores. High performance crews (who committed the least errors in flight) reported experiencing less stress in simulated flight than either low or medium crews. When comparing crew positions for perceived stress over all the simulated flights no significant differences were found. However, the crews led by the "Right Stuff" (e.g., active, warm, confident, competitive, and preferring excellence and challenges) personality type captains typically reported less stress than crewmembers led by other personality types.

We identified 28 ectomycorrhizal fungal species collected from 27 soil cores. The proportion of P. engelmannii to P. contorta ectomycorrhizae was nearly equal (52 and 48%, respectively). Of the 28 fungal species, 18 composed greater than 95% of the fungal community. No species was associated exclusively with P. contorta, but four species, each found in only one core, and one species found in two cores were associated exclusively with P. engelmannii. These fungi composed less than 5% of the total ectomycorrhizae. Thus, neither hypothesis was supported, and hypothesized benefits of ectomycorrhizal specificity to both trees and fungi probably do not exist in this system.

AN - 72289053; 11003602 AB - To evaluate the relationship between osteoblast differentiation and bioenergetics, cultured primary osteoblasts from fetal rat calvaria were grown in medium supplemented with ascorbate to induce differentiation. Before ascorbate treatment, the rate of glucose consumption was 320 nmol. h(-1). 10(6) cells(-1), respiration was 40 nmol. h(-1). 10(6) cells(-1), and the ratio of lactate production to glucose consumption was approximately 2, indicating that glycolysis was the main energy source for immature osteoblasts. Ascorbate treatment for 14 days led to a fourfold increase in respiration, a threefold increase in ATP production, and a fivefold increase in ATP content compared with that shown in immature cells. Confocal imaging of mitochondria stained with a transmembrane potential-sensitive vital dye showed that mature cells possessed abundant amounts of high-transmembrane-potential mitochondria, which were concentrated near the culture medium-facing surface. Acute treatment of mature osteoblasts with metabolic inhibitors showed that the rate of glycolysis rose to maintain the cellular energy supply constant. Thus progressive differentiation coincided with changes in cellular metabolism and mitochondrial activity, which are likely to play key roles in osteoblast function.

AN - 70535594; 12561862 AB - We revised the models for mixed irradiation by Zaider and Rossi and by Suzuki, substituting second-order repair function for a first-order one in reduction and interaction factors of the models. The reduction factor, which reduces the contribution of the square of a dose to cell killing in the models, and the interaction factor, which also reduces the contribution of the interaction of two or more doses of different types of radiation, were formulated by using the second-order repair function. These newly modified models for mixed irradiation can express or predict cell survival more accurately than the older ones, especially when irradiation is prolonged at low dose rates.

AN - 70534201; 11894872 AB - Objective. To construct an experimental facility for microorganism waste processing, which will be used to recover plant nutrient liquids from plant inedible biomass essential for growth and development of plants. Method. After technical parameters and performance requirements were defined, plan demonstration, drawing design, fabrication, debug and preliminary plant inedible residue-biodegradation tests of microorganisms were conducted. Result. The temperature, stirring speed and gas-supplying flow of bioreactor of the facility were controlled automatically, as well as the pH and dissolved oxygen concentration were measured automatically and controlled manually, testifying that its performance reached the requirements of predetermined technical indexes. The 15-d test showed that the facility ran smoothly, its above-mentioned parameters could be measured and controlled precisely, and the biodegradation rate of lettuce's inedible biomass approximately attained 90%. Conclusion. The facility holding reasonable technical indexes, smooth and dependable performances, is capable of being utilized to biodegrade plant inedible biomass. It is expected that if the above-mentioned parameter combinations are optimized further, the results should be better.

AN - 70534163; 11894866 AB - Objective. To explore prior noise exposures or sound conditioning as a moderator of hearing loss produced by traumatic exposure to low or middle-frequency noise. Method. Two experimental groups of guinea-pigs were conditioned using a 0.5 kHz octave band noise (OBN) at 85 dB, 6 h/d for 4 d. The subjects were allowed to recover for 3 d after conditioning. Then the first group was exposed to a 0.5 kHz OBN at 110 dB for 1 h, the second group was exposed to 1 kHz OBN at 110 dB for 1 h. Two control groups received 0.5 kHz and 1 kHz OBN respectively at 110 dB for 1 h without prior sound conditioning. Result. Hearing threshold shifts recorded at 48 h after the high-level noise exposure in conditioned groups and control groups demonstrated that conditioning provided significant protection on hearing threshold shift from low or middle frequency noise exposure. Histological examination revealed significantly less hair cell loss in the conditioned than in the control groups. In addition, malondialdehyde (MDA) levels in red blood cell (RBC) of conditioned groups were significantly lower as compared with that of the control groups. Conclusion. Low-frequency conditioning provided significant protection not only on hearing threshold shift caused by noise of the same frequency, but also on that caused by middle frequency noise.

After the whole body irradiation with 10 Gy of 135 MeV/u carbon-ion beam, the genomic DNA was isolated from the different organs and the lambda DNA was rescued as a lambda phage. Mutations in the transgene on the lambda DNA were determined by the spi(-) selection (deletion assay). The spi(-) mutation was induced by the above irradiation, but enhancement of the mutant frequency by the knockout of p53 gene was found not in the phages recovered from liver but in those from kidney. We are now making an effort to determine the nature of spi(-) mutation to confirm such p53 effect.

Precipitation of micritic laminae in these stromatolites was studied by comparing microstructure, as observed in petrographic thin sections, with microbial sulfate-reduction activity. Two-dimensional mapping of sulfate-reduction rates was implemented by incubating a vertical section of a stromatolite face on silver foil coated with (super 35) SO (sub 4) (super 2-) . Our results show that sulfate-reduction activity is high in zones of CaCO (sub 3) precipitation and indicate that microbial activity produces lithified micritic laminae near the surface of the stromatolites. Similarities with micritic laminae in ancient stromatolites suggest that sulfate reduction may also have been an important mechanism of carbonate precipitation in these fossilized structures.

These freshwater calcite microbialites contain microstructures similar to those of the early Cambrian Epiphyton and Girvanella. Their morphologies vary with depth, and dendritic structures of the deep-water (> 30 m) mounds may be analogues of ancient calcareous structures.

The pattern of postseismic surface deformation due to viscoelastic flow in the lower crust and asthenosphere following a major earthquake on such a fault is modified from that predicted from the conventional elastic layer over viscoelastic half-space model by the presence of the subducting slab. The predicted effects, such as a partial suppression of the postseismic velocities by 1 cm/yr or more immediately following a moderate to great earthquake, are potentially detectable using contemporary geodetic techniques.

Interference between polarised tectonic and radial deglaciation strain fields affects the deviatoric stress state and fault stability margins and, in consequence both the levels and properties of seismicity throughout glacial loading and unloading. The most notable present-day affects of this strain interference are predicted to include alternating quadrants of enhanced seismicity and aseismicity around rebound domes and former peripheral forebulges.

Lithospheric stresses induced by mass and fluid transfers associated with Quaternary ice sheets affected the tectonic regimes of stable cratons and active plate margins. In the latter case, it is difficult to differentiate glacially induced fault displacements from nonglacial ones, particularly if residual glacial stresses are considered. Glaciotectonics, a sub-subdiscipline within Quaternary geology is historically focussed on reconstructing past glacier regimes and, by definition, does not include these effects. The term "glacial tectonics" is hereby suggested for investigations focussed on the past and continuing influences of ice sheets on contemporary tectonics.

It is proposed that the large-scale lateral displacements formerly proposed can not be justified, rather all postglacial fault movements appear to be limited to metre-scale vertical movements along pre-existing fault lines. In addition, it is argued that the Younger Dryas ice advance may have produced localised crustal redepression but not the more widespread impact formerly proposed. Both tectonic and postglacial rebound stresses, however, may be needed to explain the contemporary seismotectonics of the Scottish Highlands.

Displacement vectors of the offset boreholes indicate movement towards 120-136 degrees in phyllites of the Laksefjord Nappe. At the base of the Kalak Nappe and in the Gaissa Nappe in western Porsanger, reverse-slip offset is directed almost due east. Observations of the extensional axial fractures, which are considered to have developed normal to the least principal in situ stress, (sub 3) , at the time of blasting, support a c. ESE-WNW orientation of S (sub Hmax) at or close to the surface in these parts of Finnmark, possibly with a slightly more E-W trend in western areas. The consistency of orientation of these structural features is considered to reflect a regional stress pattern and is not merely a manifestation of the local geology or topography.

In order to study this region in more detail, a local seismic network has been in operation there since July 1997, as part of the NEONOR (Neotectonics in Norway) project. The network was primarily designed to detect possible activity on the Basmoen Fault which runs approximately 50km subparallel to the Rana fjord, and which shows signs of likely post glacial activity. The results have revealed a quite complex spatio-temporal distribution of seismic activity, and has also shown no activity on the Basmoen Fault itself. During the first 18 months of operation (July 1997-January 1999), the network has detected 373 locatable seismic events, of which 267 were local earthquakes. Most of these earthquakes occurred in five groups in the western parts of the network. All five groups had similar NNW-ESW trends in epicenter locations, and all have shallow foci (2-12km), similar to what has also been found earlier for other concentrated earthquake zones in Northern Norway, and the magnitude range is between M (sub L) 0.1 and 2.8. Earthquake focal mechanism solutions within the network reveal a predominance for normal faulting with the tensional stress axis perpendicular do the coastline (implying an unusual coast-parallel orientation of the principal horizontal compressive stress). The earthquakes occur in a region of maximum post-glacial uplift gradients, which supports deglaciation flexure as a viable explanation for these earthquakes. A certain influence from more local factors, however, tied in general to crustal in homogeneities, cannot be ruled out.

This event is dated to varve 9663 BP. The Iggesund-Hudiksvall area is represented by intensive postglacial fracturing of the bedrock recorded over an area of, at least, 50 X 50km. The most remarkable locality is the Boda cave system; a hill fractured into a field of large detached blocks with a cave system of more than 2km length. In the varve-year 9663 BP, an extensive turbidite was spread over an area of 210 X 80km. Liquefaction structures are recorded over an area of 80 X 30km and can be assigned to the same varve year. Structures and deposits of a tsunami are recorded over 80 X 50km.

Glaciers and glacial erosion have dictated patterns of denudation in the orogen over the last approximately 5Myr. The orogen comprises three discrete topographic domains from south to north, respectively; (1) the Chugach/St. Elias Range; (2) the Wrangell Mountains; and (3) the eastern Alaska Range. Although present deformation is distributed across the orogen, much of the shortening and uplift are concentrated in the Chugach/St. Elias Range. A systematic increase in topographic wavelength of the range from east to west reflects east-to-west increases in the width of a shallowly dipping segment of the plate interface, separation of major upper plate structures, and a decrease in the obliquity of plate motion relative to the plate boundary. Mean elevation decays exponentially from approximately 2500 to approximately 1100m from east to west, respectively. Topographic control on the present and past distribution of glaciers is indicated by close correspondence along the range between mean elevation and the modern equilibrium line altitude of glaciers (ELA) and differences in the modern ELA, mean annual precipitation and temperature across the range between the windward, southern and leeward, northern flanks. Net, range-scale erosion is the sum of (1) primary bedrock erosion by glaciers and (2) erosion in areas of the landscape that are ice-marginal and are deglaciated at glacial minima. Oscillations between glacial and interglacial climates controls ice height and distribution, which, in turn, modulates the locus and mode of erosion in the landscape. Mean topography and the mean position of the ELA are coupled because of the competition between rock uplift, which tends to raise the ELA, and enhanced orographic precipitation accompanying mountain building, which tends to lower the ELA. Mean topography is controlled both by the 60 degrees latitude and maritime setting of active deformation and by the feedback between shortening and uplift, glacial erosion, and orographic effects on climate accompanying mountain building.

Fossil mollusc shells, most in living position and collected from raised beaches, were dated using the U-series, ESR and (super 14) C methods. Our analyses show that Holocene sea-level in this region culminated 7000 to 8000BP at 6-7m amsl. This beach slightly increases in altitude southward. The last interglacial stage (5e) was identified at 16-17m amsl whereas the highest and morphologically most distinctive radiometrically dated terrace at 250,000 to 330,000BP exists at an elevation of 33-35m amsl. We estimate a constant rate of tectonic uplift of 0.09m/1000yr since the middle Pleistocene. Using this estimate of the local rate of tectonic uplift we correct relative sea-level (r.s.l) observations for the Holocene epoch. In turn, the inferred Holocene sea-level histories are compared with those predicted using the ICE-4G (VM2) model of the global process of glacial isostatic adjustment. This model accurately predicts r.s.l history from all sites along the northern part of the east coast of the South American continent (Venezuela, Brazil). However, along the southern part of the coast of Argentinian Patagonia there is evidence of an influence that is not accurately represented in this version of the model of the global process of glacial isostatic adjustment. We suggest that this influence could be connected to the presence of the broad continental shelf that is located offshore of this region, but the influence of significant neotectonic uplift cannot be dismissed.

Extensive modelling of the isostatic movements show that the applied deglaciation and uplift model fit the observations well. There are, however, areas with significant deviations between uplift measurements and regional model predictions. The misfit between observations and the isostatic uplift modelling is interpreted here to reflect a tectonic component of the uplift. The objective of the present investigation is to isolate this tectonic uplift component. Interestingly enough, the areas found partly correspond to areas with pronounced seismic activity, and the assumption that the postglacial rebound is responsible for much of the observed onshore seismicity is substantiated. We conclude that there seems to be present-day deformation along the shoreline of mid-Norway, southern Norway (shoreline and mountain areas), and along the Swedish east coast with the centre northeast of the Gulf of Bothnia that cannot be explained by glacial isostasy. Not all of the deformations in these areas are necessarily co-seismic. The study suggests that such vertical deformations are small in magnitude and overprint the glacial rebound. The deformations may be a consequence of the Plio-Pleistocene erosional pattern, which is of glacial origin.

A postglacial rebound model explains crustal tilting and rapid uplift at the northern Cascadia subduction zone that occurred during retreat of the Cordilleran ice-sheet. Observations explained by the model include the shoreline tilts of two proglacial lakes that formed at 13.5-14ka ( (super 14) Cyr ago) and rapid sea level fall (land uplift) at 12-12.5ka. Modelled mantle viscosity values range from 5 X 10 (super 18) to 5 X 10 (super 19) Pas, and are consistent with previous viscosity inferences from observations of crustal deformation following subduction zone earthquakes (10 (super 18) -10 (super 19) Pas). No lower limit to subduction zone mantle viscosity is apparent from our model, but viscosity values equal to or larger than 10 (super 20) Pas are definitely ruled out. Our modelled subduction zone viscosity values are smaller than most upper-mantle viscosity estimates derived from postglacial rebound studies of tectonically less-active regions (10 (super 20) -10 (super 21) Pas). The rapid observed uplift at 12ka requires, in addition to a low mantle viscosity, rapid unloading from a sudden collapse of remaining coastal portions of the southern Cordilleran ice-sheet. The sudden collapse provides 0.18m of global eustatic sea level rise, approximately 0.7% of the sea level rise associated with melt-water pulse IA. Predictions of a global postglacial rebound model (ICE-3G) with a 10 (super 21) Pas upper-mantle viscosity were previously applied to geodetic data from this region to isolate signals associated with the earthquake cycle. Owing to the low-viscosity values, and resulting rapid recovery of glacial deformation, our model predicts present-day postglacial rebound uplift rates at least 10 times smaller than ICE-3G (less than about 0.1mm/yr). As the ICE-3G adjustments were substantial, this indicates the need for re-evaluation of the geodetic data.

The Stuoragurra Fault is a large reverse fault in Finnmark County. The Nordmannvikdalen Fault is a much smaller normal fault in Troms County. The Stuoragurra postglacial fault can be followed, in several discontinuous sections, for 80km, in a NE-SW direction. The fault has up to 10m of displacement. During 1998, two trenches were made across the fault. The hanging wall was seen to be thrust upwards over the footwall, with 7m vertical displacement evident from displaced glacial contacts. The fault did not penetrate the overlying glacial materials, but rather folded them, forming a blind thrust. Large liquefaction and other deformation structures were found in the glaciofluvial sediments in both trenches. Veins of angular and subangular pebbles from the local bedrock penetrate more than 10m laterally from the thrust plane and into the sediments in the footwall. It is thought that these veins were injected during the fault activity. The major deformation of the sediments has a decollement plane that continues laterally in the E/B horizon contact of the modern soil on top of the footwall. This may indicate that an initial pedogenesis had taken place before the fault activity occurred, however no macro plant fossils to support this were found in the possible buried soil. Deformational structures seen in the trench can be explained as a result of one major fault event. The Nordmannvikdalen postglacial fault is a NW-SE trending normal fault, dipping to the NE. The fault offsets till on the NW slope of Nordmannvikdalen. The escarpment varies in height from 0.5 to 1.5m, with a trench often present between the hanging wall and the footwall. The fault locally splits into two subparallel branches, however this is probably only in the glacial overburden. Ground penetrating radar (GPR) profiles show two prominent bedrock reflectors, dipping approximately 40 degrees to the NE. An upward extrapolation of the northernmost reflector through the overburden coincides with the position of the surface scarp. The bedrock is well exposed along a streamed parallel to the GPR profiles. Bedding and foliation cannot be responsible for the reflectors visible in the GPR profiles. Gravitational forces have been ruled out as the origin of the fault. Although both faults probably formed shortly after Weichselian deglaciation, there is evidence that isostatic uplift was not the only force acting. Quaternary tilting of Fennoscandia due to ridge push, or mantle convection, may also play a role in neotectonic activity in Norway.

This growth has been driven largely by the emergence of postglacial rebound models (PGM) constrained by new field observations that incorporate increasingly realistic rheological, mechanical, and glacial parameters. In this paper, we highlight some of these recent field-based investigations and new PGMs, and examine their implications for understanding crustal deformation and seismicity during glaciation and following deglaciation. The emerging glacial rebound models outlined in the paper support the view that both tectonic stresses and glacial rebound stresses are needed to explain the distribution and style of contemporary earthquake activity in former glaciated shields of eastern Canada and Fennoscandia. However, many of these models neglect important parameters, such as topography, lateral variations in lithospheric strength and tectonic strain built up during glaciation. In glaciated mountainous terrains, glacial erosion may directly modulate tectonic deformation by resetting the orogenic topography and thereby providing an additional compensatory uplift mechanism. Such effects are likely to be important both in tectonically active orogens and in the mountainous regions of glaciated shields. In general, the short-term response to ice fluctuations is similar to the Earth's response to fluctuations in water reservoirs with the subsequent increase or decrease in seismicity which depends on the pre-existing stress state. When the ice fluctuations occur on the spatial scale, and magnitude, of the late Pleistocene glaciation and deglaciation, however, the viscoelastic response of the Earth (especially the mantle) causes significant changes in crustal deformation and earthquake activity that is spatially extensive and temporally complex. The regions of greatest ice thickness and the regions marginal to the late Pleistocene ice sheets indicate the most dramatic evidence of earthquake faulting. The mantle response to these large ice mass fluctuations and the change in mass between the oceans and land caused, and continues to cause, measureable crustal deformation at hundreds of kilometres from the ice margins. For both tectonically active and cratonic regions, palaeoseismic investigations of late Pleistocene and Holocene faults are an important tool in evaluating earthquake hazard. The predicted response of the Earth over this time, however, is very dependent on the model assumed. For most regions, far more carefully designed field observations are needed to constrain the existing rheological and ice models.

The dominant feature is a 500-km-wide topographic dome that rises 3 km above the surrounding plains. This dome underlies the residual ice cap but is at least 50% larger in area. Erosional scarps and terraces indicate that this dome was once more extensive and has undergone erosional retreat. Adjacent to the dome, layered deposits form a vast plateau 1-1.5 km high extending approximately 1000 km beyond and to one side of the residual south polar cap. This plateau is relatively flat at kilometer scales, although it is cut in places by troughs and depressions, which have locally steep scarps up to 2 km high and sloping up to roughly 10 degrees . Contiguously flat kilometer-scale regions the size of the Mars Polar Lander (MPL) landing ellipse are present. These are in the form of plateaus 100-300 km wide and 1-2 km high. One of the largest of these plateaus has been proposed as a landing site for the Mars Polar Lander (MPL). The volume associated with the south polar layered deposits may be comparable to those of the layered deposits at the north pole. Although this doubles the current probable inventory of surface ice on Mars, it still falls far short of accounting for the inferred volume of water on Mars in the past.

Microorganisms, especially bacteria, secrete extracellular polymeric substances (EPS) to form slime layers in which they reproduce. In the sedimentary environment, biofilms commonly contain the products of degraded bacteria as well as allochthonous and autochthonous mineral components. They are complex structures which serve as protection for the colonies of microorganisms living in them and also act as nutrient traps. Biofilms are almost ubiquitous wherever there is an interface and moisture (liquid/liquid, liquid/solid, liquid/gas, solid/gas). In sedimentary rocks they are commonly recognized as stromatolites. We also discuss the distinction between bacterial biofilms and prebiotic films. The EPS and cell components of the microbial biofilms contain many cation chelation sites which are implicated in the mineralization of the films. EPS, biofilms, and their related components thus have strong preservation potential in the rock record. Fossilized microbial polymeric substances (FPS) and biofilms appear to retain the same morphological characteristics as the unfossilized material and have been recognized in rock formations dating back to the Early Archaean (3.5 b.y.). We describe FPS and biofilms from hot spring, deep-sea, volcanic lake, and shallow marine/littoral environments ranging up to 3.5 b.y. in age. FPS and biofilms are more commonly observed than fossil bacteria themselves, especially in the older part of the terrestrial record. The widespread distribution of microbial biofilms and their great survival potential makes their fossilized remains a useful biomarker as a proxy for life with obvious application to the search for life in extraterrestrial materials.

These wind data allowed direct measurement of near-surface wind profiles on Mars for the first time, including determination of aerodynamic roughness length and wind friction speeds. Winds were light during periods of windsock imaging, but data from the strongest breezes indicate aerodynamic roughness length of 3 cm at the landing site, with wind friction speeds reaching 1 m/s. Maximum wind friction speeds were about half of the threshold-of-motion friction speeds predicted for loose, fine-grained materials on smooth Martian terrain and about one third of the threshold-of-motion friction speeds predicted for the same size particles over terrain with aerodynamic roughness of 3 cm. Consistent with this, and suggesting that low wind speeds prevailed when the windsock array was not imaged and/or no particles were available for aeolian transport, no wind-related changes to the surface during mission operations have been recognized. The aerodynamic roughness length reported here implies that proposed deflation of fine particles around the landing site, or activation of duneforms seen by IMP and Sojourner, would require wind speeds >28 m/s at the Pathfinder top windsock height (or >31 m/s at the equivalent Viking wind sensor height of 1.6 m) and wind speeds >45 m/s above 10 m. These wind speeds would cause rock abrasion if a supply of durable particles were available for saltation. Previous analyses indicate that the Pathfinder landing site probably is rockier and rougher than many other plains units on Mars, so aerodynamic roughness length elsewhere probably is less than the 3-cm value reported for the Pathfinder site.

However, even though an empirical correlation between the rain rate or kinetic energy flux (KEF) delivered to the water surface by rain and the gas transfer velocity has been established, the physical mechanisms underlying the gas exchange enhancement remain unexamined. During a series of experiments, the processes behind rain-induced air-water gas exchange were examined at NASA's Rain-Sea Interaction Facility (RSIF). Gas transfer velocities for helium (He), nitrous oxide (N (sub 2) O), and sulfur hexafluoride (SF (sub 6) ) were determined for 22 rain rates (13.6 to 115.2 mm h (super -1) ) and three drop sizes (2.3, 2.8, 4.2 mm). Bubbles generated by the raindrops were characterized using a video-microscope technique, and surface waves were characterized by a capacitance probe. Additionally, rain-generated turbulence was inferred from friction velocities u (sub *w ) calculated from KEF. Together, these data suggest that rain-induced air-water gas exchange is mainly caused by turbulence-driven exchange processes, with bubbles contributing anywhere from 0 to 20%, depending on rain rate, drop size, and the solubility of the gas tracer. Furthermore, the data confirm that the previously selected variable KEF is the best correlate for rain-induced air-water gas exchange. Copyright 2000 by the American Geophysical Union.

The purpose of this paper is to compare the effectiveness of three treatments for motion sickness: intramuscular injections (IM) of promethazine, a physiological training method (autogenic feedback training exercise [AFTE]), and a no-treatment control. An earlier study tested the effects of promethazine on cognitive and psychomotor performance and motion sickness tolerance in a rotating chair. For the present paper, motion sickness tolerance, symptom reports, and physiological responses of these subjects were compared to matched subjects selected from an existing database who received either AFTE or no treatment. Three groups of 11 men, between the ages of 33 and 40 years, were matched on the number of rotations tolerated during their initial rotating-chair motion sickness test. The motion sickness test procedures and the 7-day interval between tests were the same for all subjects. The drug group was tested under four treatment conditions: baseline (no injections), a 25 mg dose of promethazine, a 50 mg dose of promethazine, and a placebo of sterile saline. AFTE subjects were given four 30-minute AFTE sessions before their second, third, and fourth motion sickness tests (6 hours total). The notreatment control subjects were only given the four rotating chair tests. Motion sickness tolerance was significantly increased after 4 hours of AFTE when compared to either 25 mg (p < 0.00003) or 50 mg (p < 0.00001) of promethazine. The control and promethazine groups did not differ. AFTE subjects reported fewer or no symptoms at higher rotational velocities than subjects in the control or promethazine groups. The primary physiological effect of promethazine was an inhibition of skin conductance level. The AFTE group showed significantly less heart rate and skin conductance variability during motion sickness tests administered after training JF - Journal of Clinical Pharmacology AU - Cowings, Patricia S AU - Toscano, William B AD - Space Life Sciences Division, NASA Ames Research Center, Moffett Field, California; National Aeronautics and Space Administration, Ames Research Center, Mail Stop 239-16, Moffett Field, CA 94035 Y1 - 2000/10// PY - 2000 DA - Oct 2000 SP - 1154 EP - 1165 PB - Sage Publications Ltd., 6 Bonhill St. London EC2A 4PU UK VL - 40 IS - 10 SN - 0091-2700, 0091-2700 KW - Physical Education Index KW - Skin KW - Physiology KW - Heart rate KW - Motion sickness KW - Velocity KW - Performance KW - Exercise KW - Injections KW - Exercise (programs) KW - PE 090:Sports Medicine & Exercise Sport Science UR - http://libproxy.lib.unc.edu/login?url=http://search.proquest.com/docview/21206624?accountid=14244 L2 - http://vb3lk7eb4t.search.serialssolutions.com/?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQ%3Aphysicaleducation&rft_val_fmt=info:ofi/fmt:kev:mtx:journal&rft.genre=article&rft.jtitle=Journal+of+Clinical+Pharmacology&rft.atitle=Autogenic-Feedback+Training+Exercise+Is+Superior+to+Promethazine+for+Control+of+Motion+Sickness+Symptoms&rft.au=Cowings%2C+Patricia+S%3BToscano%2C+William+B&rft.aulast=Cowings&rft.aufirst=Patricia&rft.date=2000-10-01&rft.volume=40&rft.issue=10&rft.spage=1154&rft.isbn=&rft.btitle=&rft.title=Journal+of+Clinical+Pharmacology&rft.issn=00912700&rft_id=info:doi/10.1177%2F009127000004001010 LA - English DB - Physical Education Index N1 - Date revised - 2010-01-01 N1 - Last updated - 2015-03-31 N1 - SubjectsTermNotLitGenreText - Skin; Heart rate; Physiology; Motion sickness; Velocity; Exercise; Performance; Injections; Exercise (programs) DO - http://dx.doi.org/10.1177/009127000004001010 ER - TY - JOUR T1 - The Temperature Dependence of the Liquid Water Path of Low Clouds in the Southern Great Plains AN - 20670065; 9409935 AB - Satellite observations of low-level clouds have challenged the idea that increasing liquid water content with temperature combined with constant physical thickness will lead to a negative cloud optics feedback in a decadal climate change. The reasons for the satellite results are explored using 4 yr of surface remote sensing data from the Atmospheric Radiation Measurement Program Cloud and Radiation Testbed site in the southern Great Plains of the United States. It is found that low-cloud liquid water path is approximately invariant with temperature in winter but decreases strongly with temperature in summer, consistent with satellite inferences at this latitude. This behavior occurs because liquid water content shows no detectable temperature dependence while cloud physical thickness decreases with warming. Thinning of clouds with warming is observed on seasonal, synoptic, and diurnal timescales; it is most obvious in the warm sectors of baroclinic waves. Although cloud top is observed to slightly descend with warming, the primary cause of thinning is the ascent of cloud base due to the reduction in surface relative humidity and the concomitant increase in the lifting condensation level of surface air. Low-cloud liquid water path is not observed to be a continuous function of temperature. Rather, the behavior observed is best explained as a transition in the frequency of occurrence of different boundary layer types. At cold temperatures, a mixture of stratified and convective boundary layers is observed, leading to a broad distribution of liquid water path values, while at warm temperatures, only convective boundary layers with small liquid water paths, some of them decoupled, are observed. Our results, combined with the earlier satellite inferences, suggest a reexamination of the commonly quoted 1.5 degree C lower limit for the equilibrium global climate sensitivity to a doubling of CO sub(2), which is based on models in which liquid water increases with temperature and cloud physical thickness is constant.

ESEM allows the viewing of fully hydrated specimens that have not undergone the structural or chemical alterations imposed by the extensive procedures necessary for viewing biological specimens in a vacuum. Besides allowing visualization of microorganisms in their natural form and as intact assemblages, ESEM also detects elements, especially those lighter than Si, which tend to be lost or masked by the processes used to prepare samples for conventional SEM and for TEM thin sections. In this study we report new information about the structure of bacteriogenic sulfur deposits and their relationship to the structural aspects of a natural microbial community from a cold sulfide spring.

These satellite-derived rainfall amounts are used to assess the impact of tropical cyclone rainfall in altering the geographical, seasonal, and interannual distribution of the North Pacific Ocean total rainfall during June-November when tropical cyclones are most important. To estimate these tropical cyclone rainfall amounts, mean monthly rain rates are derived from passive microwave satellite observations within 444-km radius of the center of those North Pacific tropical cyclones that reached storm stage and greater. These rain-rate observations are converted to monthly rainfall amounts and then compared with those for nontropical cyclone systems. The main results of this study indicate that 1) tropical cyclones contribute 7% of the rainfall to the entire domain of the North Pacific during the tropical cyclone season and 12%, 3%, and 4% when the study area is limited to, respectively, the western, central, and eastern third of the ocean; 2) the maximum tropical cyclone rainfall is poleward (5 degree -10 degree latitude depending on longitude) of the maximum nontropical cyclone rainfall; 3) tropical cyclones contribute a maximum of 30% northeast of the Philippine Islands and 40% off the lower Baja California coast; 4) in the western North Pacific, the tropical cyclone rainfall lags the total rainfall by approximately two months and shows seasonal latitudinal variation following the Intertropical Convergence Zone; and 5) in general, tropical cyclone rainfall is enhanced during the E1 Nino years by warm SSTs in the eastern North Pacific and by the monsoon trough in the western and central North Pacific.

We combined a comparative physiological approach with phylogenetic analyses to study the evolution of thermotolerance in hot spring cyanobacteria of the genus Synechococcus. Among the 20 laboratory clones of Synechococcus isolated from collections made along a hot spring thermal gradient, (Hunter's Hot Springs, Oregon), four different 16S rRNA gene sequences were identified. Phylogenies constructed by using the sequence data indicated that the clones were polyphyletic but that three of the four sequence groups formed a clade. Differences in thermotolerance were observed for clones with different 16S rRNA gene sequences, and comparison of these physiological differences within a phylogenetic framework provided evidence that more thermotolerant lineages of Synechococcus evolved from less thermotolerant ancestors. The extension of the thermal limit in these bacteria was correlated with a reduction in the breadth of the temperature range for growth, which provides evidence that enhanced thermotolerance has come at the evolutionary cost of increased thermal specialization. This study illustrates the utility of using phylogenetic comparative methods to investigate how evolutionary processes have shaped historical patterns of ecological diversification in microorganisms.

A 3-D scene modeling approach for these purposes is presented in this paper. This 3-D model fulfills its goal by taking advantage of radiosity theory and computer graphics techniques. It consists of two major modules: a modified extended L-systems (MELS) method to generate a 3-D realistic scene and a radiosity-graphics combined method (RGM) to calculate the radiation regime based on the 3-D structures rendered with MELS. The 3-D simulation tool is then evaluated using field measurements of both plant structure and spectra collected during the NASA Earth Observing Satellite Prototype Validation Exercise Jornada field campaign near Las Cruces, NM. The modeled scene reflectance is compared with measurements from three platforms (ground, tower, and satellite) at various scales (from the size of individual shrub component to satellite pixels of kilometers). The agreement with measured reflectances is excellent at all sampling scales tested. As an example of the model's application, we use the model output to examine the validity of a linear mixture scheme over the Jornada semidesert scene. The result shows that the larger the sampling size (at least larger than the size of the shrub component), the better the hypothesis is satisfied because of the unique structure of the Jornada scene: dense plant clumps (shrub component) sparsely scattered on a predominantly bare soil background. A range of possible applications of this 3-D scene model is highlighted, and further work needed for 3-D modeling is also discussed.

Often historical aerial photos postdate the desired time period. We developed two modeling approaches for reconstructing 1920s landcover prior to the first available 1943 aerial photographs. We concluded that one method had an advantage, but realized that availability of historic aerial photos would limit its use in many areas. For this reason, we applied both methods to the U.S. Geological Survey 7.5-minute Courtenay quadrangle on Merritt Island, Florida (USA) and compared results. Method 1 used existing maps (1943 landcover, 1900s city/transportation, and 1913/1974 soils) and assumed that areas of natural landcover in 1943 would also have been natural in 1920. Natural landcover polygons from the 1943 map were used directly and the ancillary maps were used to map urban polygons. Areas mapped as urban or transportation on the 1943 and 1900s maps remained urban, while areas mapped as urban in 1943 and not urban in the early 1900s were modeled using soil/vegetation associations. The second method used urban polygons and overlaid them with soil information; the soil/vegetation associations were then used to model all nonurban landcover polygons. The detailed map from method 1 predicted all but two types, while the second method's coarse map predicted seven fewer landcover types than were mapped in 1943. Either method (depending on modeling date and resources) can be useful for providing objective reference data to guide management of natural areas.

The QRAS is a tool designed to estimate Space Shuttle risk and evaluate Space Shuttle upgrades. This paper presents an overview of the QRAS with focus on its application for evaluating the risk reduction due to proposed Space Shuttle upgrades. The application includes a case study from the Space Shuttle main engine (SSME). The QRAS overview section of the paper includes the QRAS development process, the technical approach to model development, the QRA quantification methods and techniques, and observations concerning the complex modeling involved in QRAS. The application section of the paper describes a practical case study using QRAS models for evaluating critical Space Shuttle Program upgrades, specifically a proposed SSME nozzle upgrade. This paper presents the method for evaluating the proposed upgrade by comparing the current nozzle (old design with well- established probabilistic models) to the channel wall nozzle (new design at the preliminary design level).

In T. acidophilum ftsZ, which is involved in cell division, was found to be in an operon with the pyrF gene, which encodes orotidine-5'-monophosphate decarboxylase (ODC), an essential enzyme in pyrimidine biosynthesis. Both ftsZ and pyrF from T. acidophilum were expressed in Escherichia coli and formed functional proteins. FtsZ expression in wild-type E. coli resulted in the filamentous phenotype characteristic of ftsZ mutants. T. acidophilum pyrF expression in an E. coli mutant lacking pyrF complemented the mutation and rescued the strain. Sequence alignments of ODCs from archaea, bacteria, and eukarya reveal five conserved regions, two of which have homology to 3-hexulose-6-phosphate synthase (HPS), suggesting a common substrate recognition and binding motif.

AN - 85268149; pmid-10993310 AB - This paper examines how human face-to-face communications may be compromised by exposure to the microgravity environment of space. Although efficient face-to-face communications are acknowledged to be essential for astronauts to work safely and effectively, the space environment causes facial edema, and allows speakers and listeners to confront one another in multiple orientations that can potentially interfere with many important non-linguistic communication cues. In addition, high background noises in space shuttles and stations can mask auditory messages. Currently, the effects of spaceflight on the ability to identify facial features, to read lips, to integrate visual and auditory sensory information, and to interpret spoken messages in noisy environments while the speakers are at various orientations with respect to the listeners, are virtually unknown. Ground-based experiments conducted in our laboratory with computer-displayed facial images presented at various orientations have suggested how non-linguistic cues may be degraded by changes in the retinal orientations of facial images. The results of our ground-based studies illustrating impaired recognition of facial features in non-erect images are described, their implications for effective face-to-face communications among astronauts in space are discussed, and two experiments that can quantify the effects of microgravity on face-to-face communications in space are outlined.

The isolated rat hearts, treated for 10 min without and with 30 μM captopril or 100 μM losartan, were subjected to 30 min ischemia followed by reperfusion for 60 min and processed for the measurement of SR function and gene expression. Attenuated recovery of the left ventricular developed pressure (LVDP) upon reperfusion of the ischemic heart was accompanied by a marked reduction in SR Ca^sup 2+^-pump ATPase, Ca^sup 2+^-uptake and Ca^sup 2+^-release activities. Northern blot analysis revealed that mRNA levels for SR Ca^sup 2+^-handling proteins such as Ca^sup 2+^-pump ATPase (SERCA2a), ryanodine receptor, calsequestrin and phospholamban were decreased in the ischemia-reperfused heart as compared with the non-ischemic control. Treatment with captopril improved the recovery of LVDP as well as SR Ca^sup 2+^-pump ATPase and Ca^sup 2+^-uptake activities in the postischemic hearts but had no effect on changes in Ca^sup 2+^-release activity due to ischemic-reperfusion. Losartan neither affected the changes in contractile function nor modified alterations in SR Ca^sup 2+^-handling activities. The ischemia-reperfusion induced decrease in mRNA levels for SR Ca^sup 2+^-handling proteins were not affected by treatment with captopril or losartan. The results suggest that the improvement of cardiac function in the ischemic-reperfused heart by captopril is associated with the preservation of SR Ca^sup 2+^-pump activities; however, it is unlikely that this action of captopril is mediated through the modification of cardiac RAS. Furthermore, cardiac RAS does not appear to contribute towards the ischemia-reperfusion induced changes in gene expression for SR Ca^sup 2+^-handling proteins.[PUBLICATION ABSTRACT] JF - Molecular and Cellular Biochemistry AU - Takeo, Satoshi AU - Nasa, Yoshihisa AU - Tanonaka, Kouichi AU - Yamaguchi, Fuminari AU - Yabe, Ken-ichi AU - Hayashi, Hideki AU - Dhalla, Naranjan S Y1 - 2000/09// PY - 2000 DA - Sep 2000 SP - 227 EP - 35 CY - New York PB - Springer Science & Business Media VL - 212 IS - 1-2 SN - 03008177 KW - Biology--Cytology And Histology KW - Calcium-Binding Proteins KW - Calsequestrin KW - Ryanodine Receptor Calcium Release Channel KW - phospholamban KW - Losartan KW - Captopril KW - Calcium KW - Calcium-Transporting ATPases KW - Sarcoplasmic Reticulum Calcium-Transporting ATPases KW - Heart KW - Proteins KW - Rodents KW - Gene expression KW - Ischemia KW - Animals KW - Ryanodine Receptor Calcium Release Channel -- genetics KW - Calsequestrin -- genetics KW - Heart -- drug effects KW - Captopril -- pharmacology KW - Calcium -- metabolism KW - Rats KW - Rats, Sprague-Dawley KW - Sarcoplasmic Reticulum -- drug effects KW - Calcium-Transporting ATPases -- genetics KW - Losartan -- pharmacology KW - Calcium-Binding Proteins -- genetics KW - Renin-Angiotensin System -- drug effects KW - Male KW - Myocardial Reperfusion KW - Sarcoplasmic Reticulum -- physiology KW - Renin-Angiotensin System -- physiology KW - Heart -- physiology KW - Gene Expression Regulation -- drug effects KW - Myocardium -- metabolism UR - http://libproxy.lib.unc.edu/login?url=http://search.proquest.com/docview/756171219?accountid=14244 L2 - http://vb3lk7eb4t.search.serialssolutions.com/?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQ%3Ahealthcompleteshell&rft_val_fmt=info:ofi/fmt:kev:mtx:journal&rft.genre=unknown&rft.jtitle=Molecular+and+Cellular+Biochemistry&rft.atitle=Role+of+cardiac+renin-angiotensin+system+in+sarcoplasmic+reticulum+function+and+gene+expression+in+the+ischemic-reperfused+heart&rft.au=Takeo%2C+Satoshi%3BNasa%2C+Yoshihisa%3BTanonaka%2C+Kouichi%3BYamaguchi%2C+Fuminari%3BYabe%2C+Ken-ichi%3BHayashi%2C+Hideki%3BDhalla%2C+Naranjan+S&rft.aulast=Takeo&rft.aufirst=Satoshi&rft.date=2000-09-01&rft.volume=212&rft.issue=1-2&rft.spage=227&rft.isbn=&rft.btitle=&rft.title=Molecular+and+Cellular+Biochemistry&rft.issn=03008177&rft_id=info:doi/10.1023%2FA%3A1007174803993 LA - English DB - ProQuest Central N1 - Copyright - Kluwer Academic Publishers 2000 N1 - Last updated - 2014-08-22 DO - http://dx.doi.org/10.1023/A:1007174803993 ER - TY - JOUR T1 - In vitro evolution of a ribozyme that contains 5-bromouridine. AN - 72486325; 11543569 AB - The Tetrahymena group I ribozyme was modified by replacing all 99 component uridine residues with 5-bromouridine. This resulted in a 13-fold reduction in catalytic efficiency in the RNA-catalyzed phosphoester-transfer reaction compared to the behavior of the unmodified ribozyme. A population of 10(13) variant ribozymes was constructed, each containing 5-bromouridine in place of uridine. Five successive 'generations' of in vitro evolution were carried out, selecting for improved phosphoester transferase activity. The evolved molecules exhibited a 27-fold increase in catalytic efficiency compared to the wild-type bromouridine-containing ribozyme, even exceeding that of the wild-type ribozyme in the non-brominated form. Three specific mutations were found to be responsible for this altered behavior. These mutations enhanced activity in the context of 5-bromouridine, but were detrimental in the context of unmodified uridine. The evolved RNAs not only tolerated but came to exploit the presence of the nucleotide analogue in carrying out their catalytic function.

AN - 72365517; 11055161 AB - Gaseous NH3 removal was studied in laboratory-scale biofilters (14-L reactor volume) containing perlite inoculated with a nitrifying enrichment culture. These biofilters received 6 L/min of airflow with inlet NH3 concentrations of 20 or 50 ppm, and removed more than 99.99% of the NH3 for the period of operation (101, 102 days). Comparison between an active reactor and an autoclaved control indicated that NH3 removal resulted from nitrification directly, as well as from enhanced absorption resulting from acidity produced by nitrification. Spatial distribution studies (20 ppm only) after 8 days of operation showed that nearly 95% of the NH3 could be accounted for in the lower 25% of the biofilter matrix, proximate to the port of entry. Periodic analysis of the biofilter material (20 and 50 ppm) showed accumulation of the nitrification product NO3- early in the operation, but later both NO2- and NO3- accumulated. Additionally, the N-mass balance accountability dropped from near 100% early in the experiments to approximately 95 and 75% for the 20- and 50-ppm biofilters, respectively. A partial contributing factor to this drop in mass balance accountability was the production of NO and N2O, which were detected in the biofilter exhaust.

AN - 70540915; 12090268 AB - The effects of light on gravitaxis and velocity in the bi-flagellated green alga Chlamydomonas reinhardtii were investigated using a real time automatic tracking system. Three distinct light effects on gravitaxis and velocity with parallel kinetics were found. Photosynthetically active continuous red light reversibly enhances the swimming velocity and increases or decreases the precision of gravitaxis, depending on its initial level. Blue light flashes induce fast transient increases in velocity immediately after the photophobic response, and transiently decrease or even reverse negative gravitaxis. The calcium dependence of this response, its fluence-response curve and its spectral characteristics strongly suggest the participation of chlamy-rhodopsin in this effect. The third response, a prolonged activation of velocity and gravitaxis, is also induced by blue light flashes, which can be observed even in calcium-free medium.

AN - 70533578; 12143886 AB - Free-standing magnetoelastic thick-film sensors have a characteristic resonant frequency that can be determined by monitoring the magnetic flux emitted from the sensor in response to a time varying magnetic field. This property allows the sensors to be monitored remotely without the use of direct physical connections, such as wires, enabling measurement of environmental parameters from within sealed, opaque containers. In this work, we report on application of magnetoelastic sensors to measurement of atmospheric pressure, fluid-flow velocity, temperature, and mass load. Mass loading effects are demonstrated by fabrication of a remote query humidity sensor, made by coating the magnetoelastic thick film with a thin layer of solgel deposited Al2O3 that reversibly changes mass in response to humidity. c2000 Elsevier Science S.A.

Their origin is uncertain, but several mutually exclusive hypotheses have been proposed, ranging from extraterrestrial to crustal, and mantle provenance. In an endeavor to further our understanding of these diamonds, we performed a series of magnetic characterization studies on 20 samples from the CAR. Our results reveal that the carbonados contain material with contrasting magnetic hysteresis behavior and magnetization. Acid leaching permitted us to monitor the distribution of magnetic carriers within the samples. An absence of sample size dependence on magnetization loss indicates that the magnetic carriers are distributed at the vitreous surface; including open pores and that the carbonado interior is essentially devoid of the magnetic carriers. The diamond's isolated non-magnetic interior of carbonados suggests that the initial formation environment was deficient in magnetic particles. The formation of the magnetic carriers is thus closely linked with the origin of the smooth surface, perhaps during the hypervelocity ejection of carbonados into the Earth's atmosphere. Partial ablation in the Earth's primordial, oxygen-poor atmosphere resulted in a fusion of the originally porous material and a decrease in the original pore density at the surface. Secondary mineralization of the impact-generated melt and/or the products of later diagenetic processes, containing the majority of the magnetic carriers, filled the remainder of the open pores.

For kinetic reasons, this ideal state is rarely established. Equilibrium describes the state of a system, but not how it got there. Still, we accept that metamorphic reactions will not occur at the P-T conditions predicted by the experimentally determined phase equilibria stability curves. Instead such reactions require metamorphic overstepping to provide the driving force to adjust the mineralogy to the new P-T conditions.

Bulk chemical analyses and observations of these rims indicate the presence of phyllosilicates and disseminated opaques. Because phyllosilicates could not have survived the chondrule formation process, chondrule silicate rims must have formed entirely by late-state aqueous reactions. As such, these textures provide a useful benchmark for isolating alteration features from more complex CM matrix materials. Both chondrule silicate and matrix silicate rims exhibit morphological features commonly associated with advancing stages of replacement reactions in terrestrial serpentinites. Contacts between many matrix silicate rims and the adjacent matrix materials suggest that these rims formed entirely by aqueous reactions in a parent-body setting. This contrasts with previous assertions that rim textures can only form by the accretion of nebular dust but does not imply an origin for the rims surrounding other types of CM core components, such as chondrules.

Thermoremanent magnetization (TRM) in single domain (SD) and multidomain (MD) sized magnetite, hematite, and pyrrhotite, all potential minerals, are considered. The intensity of TRM (in 0.05 mT) is in descending order: SD-sized magnetite, SD-sized pyrrhotite, MD-sized hematite, MD-sized pyrrhotite, MD-sized magnetite, SD-sized hematite. The TRM intensity is 50% of the SIRM. Each of these minerals and estimated concentrations of magnetic remanence carriers (assumed to be titanomagnetite) in the Shergotty-Nakhla-Chassigny martian meteorites are used in a thin sheet approximation model to reveal the concentration of each mineral required for the generation of an observed magnetic anomaly (1500 nT at 100 km altitude) assuming TRM acquisition in a 0.05 mT magnetic field.

Almost all olivine grains in Nakhla contain dark lamellar inclusions (less than 2-3 mu m wide). High-resolution scanning and transmission electron microscopy revealed that the inclusions are complex intergrowths of augite and magnetite. Such a symplectic intergrowth of augite and magnetite in olivine was known in some terrestrial rocks, lunar rocks, and a few meteorites. The inclusion in Nakhla olivine is the first symplectite found in a martian rock. Apparently, the presence of Fe (super 3+) in olivine under an oxidizing condition on Mars caused symplectic exsolution at high temperature (>900 degrees C) during cooling.

The classical interpretation assumes that the present-day spatial isotope/surface temperature slope can be used for interpreting paleodata. In Greenland this interpretation is now being challenged. A General Circulation Model (GCM) applied to Antarctic conditions showed that during the time period between the Last Glacial Maximum and in the current era, seasonal variations in precipitation and cooling of the moisture sources took place. From analysis of these changes and their impact on the isotopic record of the Antarctic local temperature, the classical interpretation of isotope records in central Antarctica was strengthened.

These include five primary units (plains, chaos, band, ridge, and crater materials) and their subunits, along with various tectonic structures such as faults. Plains units are the most widespread. Ridged plains material spans a wide range of geological ages, including the oldest recognizable features on Europa, and appears to represent a style of tectonic resurfacing, rather than cryovolcanism. Smooth plains material typically embays other terrains and units, possibly as a type of fluid emplacement, and is among the youngest material units observed. At global scales, plains are typically mapped as undifferentiated plains material, although in some areas differences can be discerned in the near infrared which might be related to differences in ice grain size. Chaos material is composed of plains and other preexisting materials that have been severely disrupted by inferred internal activity; chaos is characterized by blocks of icy material set in a hummocky matrix. Band material is arrayed in linear, curvilinear, wedge-shaped, or cuspate zones with contrasting albedo and surface textures with respect to the surrounding terrain. Bilateral symmetry observed in some bands and the relationships with the surrounding units suggest that band material forms by the lithosphere fracturing, spreading apart, and infilling with material derived from the subsurface. Ridge material is mapped as a unit on local and some regional maps but shown with symbols at global scales. Ridge material includes single ridges, doublet ridges, and ridge complexes. Ridge materials are considered to represent tectonic processes, possibly accompanied by the extrusion or intrusion of subsurface materials, such as diapirs. The tectonic processes might be related to tidal flexing of the icy lithosphere on diurnal or longer timescales. Crater materials include various interior (smooth central, rough inner, and annular massif) and exterior (continuous ejecta) subunits. Structural features and landforms are shown with conventional symbols. Type localities for the units are identified, along with suggestions for portraying the features on geological maps, including colors and letter abbreviations for material units. Implementing these suggestions by the planetary mapping community would facilitate comparisons of maps for different parts of Europa and contribute to an eventual global synthesis of its complex geology. On the basis of initial mapping results, a stratigraphic sequence is suggested in which ridged plains form the oldest unit on Europa, followed by development of band material and individual ridges. Band materials tend to be somewhat older than ridges, but in many areas the two units formed simultaneously. Similarly, the formation of most chaos follows the development of ridged plains; although chaos is among the youngest materials on Europa, some chaos units might have formed contemporaneously with ridged plains. Smooth plains generally embay all other units and are late-stage in the evolution of the surface. C1 craters are superposed on ridged plains but are crosscut by other materials, including bands and ridges. Most c2 craters postdate all other units, but a few c2 craters are cut by ridge material. C3 craters constitute the youngest recognizable material on Europa. Copyright 2000 by the American Geophysical Union.

Since the early 1980's biologists at Kennedy Space Center have monitored hatchling emergences in order to document any impacts the space program has on their seaward orientation. Although tremendous improvements in light management were made, and nest disorientations were reduced to almost zero, no local baseline data on the hatchling's innate seaward behavior exist. We did not know if a 2-5% disorientation rate could be considered a "natural" phenomenon.

Structural measurements were made in a series of secondary forest stands, from 4-30 y old, in Brazil and Bolivia. Half of the stands were forest regrowth following clearance and only 1 y of cultivation; the other half were regrowth following 4 y or more of continuous pasture in Brazil and three or more rotations of medium-fallow agriculture in Bolivia. Above-ground live biomass was estimated using published allometric equations. Total biomass ranged from 17 to 207 Mg ha super(-1). Biomass of pioneer trees was poorly related to stand age, while that of later-successional trees increased linearly with age. Total biomass accumulation in Bolivia averaged 5.4 Mg ha super(-1) y super(-1) over the entire age sequence. Biomass accumulation for regrowth following short-term use was not greater than that for regrowth following medium-fallow agriculture. In Brazil, biomass accumulation averaged 9.1 Mg ha super(-1) y super(-1) over the first 12 y of regrowth and 5.9 Mg ha super(-1) y super(-1) over the entire age sequence. Biomass accumulation was significantly slower, around 5.0 Mg ha super(-1) y super(-1), for regrowth following continuous pasture than for regrowth following 1 y of cultivation.

AN - 72487173; 11543547 AB - High-sensitivity detection of formaldehyde (CH2O) at 3.5315 micrometers (2831.64 cm-1) is reported with a diode-laser-pumped, fiber-coupled, periodically poled LiNbO3 spectroscopic source. This source replaced the Pb-salt diode laser Dewar assembly of an existing tunable diode-laser absorption spectrometer designed for ultrasensitive detection of CH2O. Spectra are recorded with 2f-modulation spectroscopy and zero-air rapid background subtraction. Initial measurements reported here, determined from multiple measurements of a flowing 7.7 parts per billion by volume (ppbv, parts in 10(9)) CH2O in air mixture, indicate replicate precisions as low as 0.24 ppbv.

This particular sensor is based on a cw fiber-amplified near-infrared (distributed Bragg reflector) diode laser and an external cavity diode laser that are frequency converted in a periodically poled lithium niobate crystal to the mid-IR spectroscopic fingerprint region (3.3-4.4 micrometers). A continuous absorption spectrum of CH4 and H2CO from 3.37 to 3.10 micrometers with a spectral resolution of 40 MHz (approximately 0.0013 cm-1) demonstrated the spectral performance that can be achieved by means of automated wavelength tuning and phase matching with stepper motor control. Autonomous long-term detection of ambient CO2 and CH4 over a 3- and 7-day period was also demonstrated.

Kaidun is a unique chondritic breccia containing a huge variety of fragments of different chondritic types. Florenskyite was found as four dispersed grains with a maximum dimension of 14 mu m within a single mass of Fe-rich serpentine within one Kaidun clast. Florenskyite is associated with submicrometer-sized grains of pentlandite and small (up to 1.5 mu m in width) laths of a still uncharacterized Fe-Cr phosphide. Florenskyite is creamy white in reflected light, and its luster is metallic. The average of three electron microprobe analyses gave (wt%) Fe 40.52, Ti 30.08, Ni 5.47, Cr 0.93, V 0.91, Co 0.60, P 21.69, Si 0.59, sum 100.79, corresponding to Fe (sub 1.01) (Ti (sub 0.87) Ni (sub 0.13) Cr (sub 0.03) V (sub 0.02) CO (sub 0.01) ) (sub 1.06) (P (sub 0.97) Si (sub 0.03) ) . Single-crystal structure analysis was performed on florenskyite using a Laue pattern collected from a multiple crystal by in-situ synchrotron X-ray diffraction. Florenskyite crystallizes in the space group Pnma, and has the anti-PbCl (sub 2) structure. Previously determined cell constants of synthetic material [a = 6.007(1), b = 3.602(1), c = 6.897(1) Aa] were used in the single-crystal data reduction. We used the POWD12 program to calculate a powder XRD pattern; the 5 most intense reflections are d = 2.301 (I = 100), 2.188 (88), 2.307 (47), 1.938 (45), and 1.801 Aa (45). Florenskyite is only the fourth phosphide to be described from nature. Its paragenesis may be unique, and may be due to melting of a mineral assemblage including Fe-Ni metal, schreibersite, daubreelite, osbornite, or heideite and subsequent crystallization of phosphides from the melt.

Incorporation followed a sigmoidal pattern similar to growth curves. At all temperatures, the log phase was followed, within 200 to 350 days, by a stationary phase, which was monitored until the 550th day of activity. The minimum doubling times ranged from 1 day (5 degrees C) to 20 days (-10 degrees C) to ca. 160 days (-20 degrees C). The curves reached the stationary phase, which is generally considered to be reached when the availability of nutrients becomes limiting, was brought on under our conditions by the formation of diffusion barriers in the thin layers of unfrozen water known to be present in permafrost soils, the thickness of which depends on temperature.

Impact melt volumes, however, exceed transient cavities volumes at diameters > 400 km on Earth, compared to > 3000 km on the moon. At these sizes, terrestrial impact basins formed in strengthless melt pools and would not have the "traditional" morphology of lunar multi-ring basins. The Earth's earliest crust was likely basaltic. Basaltic bodies in the terrestrial environment differentiate, as a function of thickness. Thus, these multi-kilometer deep melt pools would have differentiated, in much the same manner as the Sudbury Igneous Complex in the approximately 250 km diameter Sudbury Structure. The largest envisaged impact event(s) would have resulted in the production of approximately 0.5 X 10 (super 9) km (super 3) of felsic differentiates. Averaged over the approximately 800 Ma of "heavy bombardment", this is approximately 30% the present annual rate of growth of continental crust. The character of the earliest continental crust is speculative, but the partial melting of hydrated oceanic crust beneath some unspecified buoyant crust is a common theme for the production of the earliest tonalitic and trondhjemitic rocks. The felsic differentiates of the large impact melt pools are candidates for this buoyant crust and may have played a role in the formation and evolution of protocontinents.

We identify: (1) a model for effecting increased diversity in the United States; and (2) a need for better ES training worldwide. In the USA certain groups are markedly underrepresented. In the past 20 years, there have been improvements in gender representation, but ethnic diversity has remained disappointing. A broad and sustained effort to enhance ES diversity in the USA could be made by a coalition of federal, state, and local agencies, which support significant ES activities. On a global scale diversity translates into the importance to train earth scientists in all global regions. The societal, political and economic competition for the distribution of regional water, environmental, mineral and hydrocarbon resources underscore the importance for a distributed and well-educated Earth Science workforce. Although these problems are different, experience suggests that both may best be addressed through sustained, systemic approaches. In the USA, umbrella entities such as Land, Sea, and Space Grant University programs might afford modest but required organizational structure. An internationally based group to examine these issues will be explored.

Ishtar Terra is a complex feature because is the site of both compression along its border and volcanism within its interior; four mountain belts surround a large volcanic plateau, Lakshmi Planum. The investigated area comprises an arcuate mountain belt, Akna Montes associated with an outboard plateau, Atropos Tessera, to the West and a volcanic plateau, Lakshmi Planum, to the East. Eight geologic units have been recognized on the basis of their geomorphic and tectonic characteristics as they appear on radar images. Our stratigraphic analysis shows the geological evolution of the study area can be explained in four main steps: 1) formation of the older substrata of Atropos Tessera and Lakshmi, 2) extensive plains emplacement, 3) orogenic phase and formation of Akna Montes, 4) local emplacement of younger plains. The tectonic evolution shows a deformational sequence characterized by contraction, shear and topographic relaxation which is interpreted to be a consequence of the variation of crustal stresses and crustal thickening during orogenic events as observed for terrestrial high plateau associated with a mountain belt. Using two end-members for structural style of Akna Montes, we estimated the amount of crustal shortening associated with the mountain belt for a symmetric fold model and a fault- bend folds model. A large difference between these values has been found, underscoring the importance of strain estimation to define a geodynamic model for orogeny on Venus.

A global distribution of radial (B (sub r) ) magnetic field observations and associated uncertainties is inverted for an equivalent source magnetization distribution and then used to generate an altitude- normalized map of B (sub r) at 200 km. The observations are well-represented by a potential function of crustal origin, consistent with a remanent origin for the Martian magnetic features. The correlation between the 40546 B (sub r) observations and B (sub r) calculated from the magnetization solution at observation locations is 0.978. For a magnetization distribution confined to a 50 km layer, calculated magnetizations range from -22 to +17 A/m. We see correlations with tectonics that were only hinted at in earlier maps. Magnetic features appear to be truncated against Valles Marineris and Ganges Chasma, suggestive of a major change in crustal properties associated with faulting.

Cloud parameters and precipitable water derived from NOAA-9 HIRS2 were used to aid in screening for clouds and water vapor in the analyses. Our results indicate that under "cloud-free" and "dry" conditions there is a good correlation between the ERBE TOA outgoing longwave fluxes and the TOMS aerosol index measurements over both land and ocean in areas under the influence of airborne Saharan dust. The ERBE TOA outgoing shortwave fluxes were also found to correlate well with the dust loading derived from TOMS over ocean. However, the calculated shortwave forcing of Saharan dust aerosols is very weak and noisy over land for the range of solar zenith angle viewed by the NOAA-9 ERBE in 1985. Sensitivity factors of the TOA outgoing fluxes to changes in aerosol index were estimated using a linear regression fit to the ERBE and TOMS measurements. The ratio of the shortwave-to-longwave response to changes in dust loading over the ocean is found to be roughly 2 to 3 but opposite in sign. The monthly averaged "clear-sky" TOA direct forcing of airborne Saharan dust was also calculated by multiplying these sensitivity factors by the TOMS monthly averaged "clear-sky" aerosol index. Both the observational and theoretical analyses indicate that the underlying surface properties, dust layer height, ambient moisture content, and the presence of cloud all play important roles in determining the TOA direct radiative forcing due to mineral aerosols.

The observations resulted in a map of the O (sub 2) dayglow which extends from 1000 to 1645 in local time and from 45 degrees S to 75 degrees N. The O (sub 2) dayglow is formed by photolysis of high-altitude ozone, and this dayglow is the best tracer of seasonal variations in photochemistry at low and middle latitudes, Our observations show that O (sub 2) dayglow can be mapped with existing ground-based instruments. The measured dayglow intensities display a gradual increase from 1.5 MR at 75 degrees N to 2.5 MR at 20 degrees N, a weak minimum of 2.3 MR at the equator, and a steep increase to 5 MR at 35 degrees -40 degrees S. The dayglow in a low-latitude belt from 5 degrees S to 25 degrees N (which is centered between the equator and the subsolar latitude) is maximum at 2.5 MR near 1300 and decreases to 1.5 MR at 1000 and 1645 LT. The observed dayglow intensities are smaller than those calculated using the model of Clancy and Nair [1996] by a factor of nearly equal 3. The observation confirms the anticorrelation between ozone and water vapor observed from the Viking orbiters at midsummer. Coupled with the Thermal Emission Spectrometer (TES) observations of temperature, dust, and water vapor, the O (sub 2) dayglow measurements comprise a good database to study Mars' photochemistry and dynamics.

The simulations use a realistic reconstruction of the paleocontinental distribution and test the following forcings, alone and in combination: 6% solar luminosity decrease, four atmospheric CO (sub 2) scenarios (1260, 315, 140, and 40 ppm), a 50% increase and a 50% decrease in ocean heat transports, and a change in obliquity to 60 degrees . None of the forcings, individually, produced year-round snow accumulation on low-latitude continents, although the solar insolation decrease and 40 ppm CO (sub 2) scenarios allowed snow and ice to accumulate at high and middle latitudes. Combining forcings further cools the climate: when solar luminosity, CO (sub 2) , and ocean heat transports were all decreased, annual mean freezing and snow accumulation extended across tropical continents. No simulation would have initiated low-latitude glaciation without contemporaneous glaciation at higher latitudes, a finding that matches the distribution of glacial deposits but which argues against high obliquity as a cause of the Varanger ice age. Low-level clouds increased in most scenarios, as did surface albedo, while atmospheric water vapor amounts declined; all are positive feedbacks that drive temperatures lower. In the most severe scenario, global snow and ice cover increased to 68%, compared to 12% under modern conditions, and water vapor dropped by 90%. These results do not necessarily preclude a "snowball" Earth climate scenario for the Varanger glacial interval. However, either more severe forcings existed or radical changes occurred in the ocean/atmosphere system which are unaccounted for by the GCM. Also, as sea ice extent increased in these experiments, snow accumulation began to decline, because of an increasingly dry atmosphere. Under snowball Earth conditions, glaciation would be impossible, since the hydrological cycle would all but cease if the atmosphere's primary moisture source were cut off.

While the role of flightdeck human error has received much emphasis, recently more attention has been directed toward reducing human error in maintenance and inspection. Aviation maintenance and inspection tasks are part of a complex organization, where individuals perform varied tasks in an environment with time pressures, sparse feedback, and sometimes difficult ambient conditions. These situational characteristics, in combination with generic human erring tendencies, result in varied forms of error. The most severe result in accidents and loss of life. For example, failure to replace horizontal stabilizer screws on a Continental Express aircraft resulted in in-flight leading-edge separation and 14 fatalities. While errors resulting in accidents are most salient, maintenance and inspection errors have other important consequences (e.g., air turn-backs, delays in aircraft availability, gate returns, diversions to alternate airports) which impede productivity and efficiency of airline operations, and inconvenience the flying public. This paper reviews current approaches to identifying, reporting, and managing human error in aviation maintenance and inspection. As foundation for this discussion, we provide an overview of approaches to investigating human error, and a description of aviation maintenance and inspection tasks and environmental characteristics.

Surfactant phytotoxicity and the potential for growth of human-associated microorganisms were assessed in studies of wheat and lettuce in controlled environmental chambers to provide baseline information for future studies with actual graywater streams. Igepon TC-42 (sodium N-coconut acid-N-methyl taurate), a surfactant designated for use on the International Space Station and a common ingredient of soaps and detergents, was added to plant systems in three different modes: (1) pulse addition of 875 mg m super(-2) growing area once a day, (2) continuous addition of 875 mg m super(-2) over the course of a day, and (3) variable addition of 0-3000 mg m super(-2) d super(-1) based on plant water demand. The survival of three human-associated bacteria (Escherichia coli, Staphylococcus aureus, and Pseudomonas aeruginosa) in the plant nutrient delivery systems were monitored following introduction 6 (wheat) or 3 (lettuce) days after planting (DAP). Igepon rapidly disappeared (i.e., a half-life of less than 1 h) following an initial adaptation period lasting less than 2 days. Microbial degradation of Igepon was supported by appearance of the degradation intermediate methyl taurine and an increase in the numbers of bacteria able to grow on media containing Igepon as the sole carbon source in the Igepon treated systems relative to the control. Wheat growth was not significantly affected by any of the Igepon treatments, but lettuce yield was significantly reduced in the pulse and continuous treatments. E. coli and S. aureus decreased below detection limits within 3-5 days within the systems, but P. aeruginosa persisted in the rhizosphere, nutrient solution, and nutrient delivery system biofilm for the duration of the wheat (70-day) and lettuce (28-day) experiments.

AN - 70513713; 11760771 AB - A one-week in situ intercomparison campaign was completed on the Rice University campus for measuring HCHO using three different techniques, including a novel optical sensor based on difference frequency generation (DFG) operating at room temperature. Two chemical derivatization methods, 2,4-dinitrophenylhydrazine (DNPH) and o-(2,3,4,5,6-pentafluorobenzyl) hydroxylamine (PFBHA), were deployed during the daylight hours for three- to four-hour time-integrated samples. A real-time optical sensor based on laser absorption spectroscopy was operated simultaneously, including nighttime hours. This tunable spectroscopic source based on difference frequency mixing of two fiber-amplified diode lasers in periodically poled LiNb03 (PPLN) was operated at 3.5315 micrometers (2831.64 cm 1) to access a strong HCHO ro-vibrational transition free of interferences from other species. The results showed a bias of -1.7 and -1.2 ppbv and a gross error of 2.6 and 1.5 ppbv for DNPH and PFBHA measurements, respectively, compared with DFG measurements. These results validate the DFG sensor for time-resolved measurements of HCHO in urban areas.

AN - 36418500; 8090 AB - PURPOSE: The implementation of runway and other improvements at Cleveland Hopkins International Airport (CLE), located in Cleveland in northeastern Ohio, is proposed. The commercial airport is located on approximately 1,600 acres of land bounded on the north by Brookpark Road and Interstate 80, on the east by the parallel transportation corridors of the Conrail Railroad and State Route 237, on the south by the Rocky River Reservation and Abram Creek, and on the west by the National Aeronautics (NASA) and Space Administration's John Glenn Research Center. The airfield system consists of three primary runways, two parallel runways, and a crosswind runway. CLE is a major hub for Continental Airlines, which accounts for 55 percent of all passengers passing through the facility. Several other major passenger and 10 cargo carriers operate at CLE. The character of CLE has changed as the Continental hub has matured and the projected activity levels have continued to show growth. No runway at CLE completely meets current federal design standards. Six alternatives, including a No-Build/No Action Alternative (Alternative 1), are considered in this final EIS. Under the sponsor's proposed action (Alternative 6), the project would involve the construction of a replacement Runway 5L/23R and associated lighting and navigational aids; the shifting of Runway 5R/23L by 960 feet to the southwest along its centerline, and the construction of a 2,250-foot extension; the development of associated ancillary facilities; the implementation of air traffic as a result of the above, as well as those actions recommended in the 2000 Final Part 150 Study Update; and the implementation of land use mitigation actions recommended in the 2000 Final Part 150 Study Update. Ancillary facilities would include parking, air cargo, airline maintenance, navigational aids and lighting, and other support facilities. Air traffic procedural changes would largely involve actions associated with noise abatement. Alternatives are considered for runway development and ancillary facilities, with discrete alternatives considered for noise abatement measures. POSITIVE IMPACTS: The proposed action would modernize the two main parallel runways at CLE such that airfield geometry, distance between runway centerlines, and the lengths and width of runway safety areas and object free areas would meet current federal design standards. Unacceptable levels of delay with respect to takeoffs and landings would be reduced. Sufficient terminal gate capacity for commuter aircraft and domestic and international jet aircraft would be provided. Aircraft noise affecting surrounding communities would be reduced. The flow and capacity of roadway access and egress would be enhanced. NEGATIVE IMPACTS: The project could require the relocation of several NASA facilities currently located at the Glenn Research Center at Lewis Field as well as some commercial relocations. Landing and takeoff delays would continue, though at less unacceptable levels. Aircraft emissions would increase due to greater taxi distances, and air quality standards would be violated at certain roadway intersections in he vicinity of the air port. The Rocky River Reservation, which is a federally funded preserve, would be adversely affected by aircraft noise as would one or two public parks and nine historic structures. The historic NASA Rocket Engine Test Facility would be demolished. From 141.79 to 164.45 acres of vegetational communities would be displaced, including 78 acres of blunt mountain mint habitat, a federally protected plant species. Approximately five acres of floodplain and 76.06 to 87.75 acres of wetlands would be graded and filled. Hazardous waste impacts would be experiences in several areas.

AN - 72622721; 11708367 AB - Galileo has completed the Europa leg of the Galileo Europa Mission, and is now pumping down the apojove in each succeeding orbit in preparation for the Io phase. Including three encounters earlier in the primary mission, the total of ten close passes by Europa have provided a wealth of interesting and provocative information about this intriguing body. The results presented include new and exciting information about Europa's interactions with Jupiter's magnetosphere, its interior structure, and its tantalizing surface features, which strongly hint at a watery subsurface layer. Additional data concerning Callisto, and its own outlook for a subsurface ocean are also presented. In addition the engineering aspects of operating the spacecraft during the past year are explored, as well as a brief examination of what will be the challenges to prepare for the Io encounters. The steadily increasing radiation dosage that the spacecraft is experiencing is well beyond the original design parameters, and is contributing to a number of spacecraft problems and concerns. The ability of the flight team to analyze and solve these problems, even at the reduced staffing levels of an extended mission, is a testament to their tenacity and loyalty to the mission. The engineering data being generated by these continuing radiation-induced anomalies will prove invaluable to designers of future spacecraft to Jupiter and its satellites. The lessons learned during this arduous process are presented. c 2000 International Astronautical Federation. Published by Elsevier Science Ltd. All rights reserved.

AN - 72601687; 11708369 AB - In the past two years, NASA has begun to develop and implement plans for investigations on robotic Mars missions which are focused toward returning data critical for planning human missions to Mars. The Mars Surveyor Program 2001 Orbiter and Lander missions will mark the first time that experiments dedicated to preparation for human exploration will be carried out. Investigations on these missions and future missions range from characterization of the physical and chemical environment of Mars, to predicting the response of biology to the Mars environment. Planning for such missions must take into account existing data from previous Mars missions which were not necessarily focused on human exploration preparation. At the same time, plans for near term missions by the international community must be considered to avoid duplication of effort. This paper reviews data requirements for human exploration and applicability of existing data. It will also describe current plans for investigations and place them within the context of related international activities. c 2000 International Astronautical Federation.

AN - 72488167; 11543565 AB - Arabinogalactan protein and wall-associated kinase (WAK) are suspected to be regulatory players at the interface between cytoplasm and cell wall. Both WAK(s) and arabinogalactan shown likely to represent arabinogalactan protein(s) have been visualized there with computational optical-sectioning microscopy. The arabinogalactan occurs in a polyhedral array at the external face of the cell membrane. WAK, and other proteins as yet unidentified, appear to fasten the membrane to the wall at vertices of the array. Evidence is presented that the array bears an important part of the mechanical stress experienced by the membrane, and it is speculated that the architectural organization of arabinogalactan protein, WAK, and other components of the array is critical for coordination of endomembrane activities, growth, and differentiation.

AN - 71282925; 10923617 AB - To determine the number of initial chromatid breaks induced by low- or high-LET irradiations, and to compare the kinetics of chromatid break rejoining for radiations of different quality. Exponentially growing human fibroblast cells AG1522 were irradiated with gamma-rays, energetic carbon (290MeV/u), silicon (490MeV/u) and iron (200 and 600 MeV/u). Chromosomes were prematurely condensed using calyculin A. Chromatid breaks and exchanges in G2 cells were scored. PCC were collected after several post-irradiation incubation times, ranging from 5 to 600 min. The kinetics of chromatid break rejoining following low- or high-LET irradiation consisted of two exponential components representing a rapid and a slow time constant. Chromatid breaks decreased rapidly during the first 10min after exposure, then continued to decrease at a slower rate. The rejoining kinetics were similar for exposure to each type of radiation. Chromatid exchanges were also formed quickly. Compared to low-LET radiation, isochromatid breaks were produced more frequently and the proportion of unrejoined breaks was higher for high-LET radiation. Compared with gamma-rays, isochromatid breaks were observed more frequently in high-LET irradiated samples, suggesting that an increase in isochromatid breaks is a signature of high-LET radiation exposure.

AN - 70542338; 12697564 AB - Phytoferritin is an iron-protein complex analogous to the ferritin found in mammalian, bacteria and fungi cells. Phytoferritin molecules are large proteins, about 10.5 nm in diameter, visualised in an electron microscope as discrete, electron dense particles with iron-containing core, where several thousand atoms of iron lie within the proteinaceous shell (apoferritin). In higher plants, a plastid stroma is the site of phytoferritin storage. Phytoferritin is seen in all types of plastids. It is considered to be a mechanism used by cells to store iron in a non-toxic form. Phytoferritin-bound iron may subsequently be used to form iron-containing components. It was shown that low levels of phytoferritin are synthesised in normal green leaves, whereas chlorotic leaves do not have a measurable amount of phytoferritin and leaves of iron-loaded seedlings contain a high level of total iron, and phytoferritin well-filled by iron. Phytoferritin accumulation was observed in photosynthetic inactivity chloroplasts during senescence and disease. In this study we analised the effects of microgravity and ethylene on production of phytoferritin in the root cap columella cells of soybean seedlings.

AN - 70538225; 12697531 AB - Effects of heavy water (D2O) on various organisms have been extensively studied and a majority of D2O actions were generally ascribed to the viscosity (1.23 times of H2O) and a larger inter-molecule force of D2O that may eventually alternate molecular structure of various enzymes and ion channels. It is reported that chronic application of D2O induces toxic effects and the 35% substitution of whole body water with D2O induced fatal effects in the mouse. Mitosis of a fertile egg of sea urchin was completely inhibited by 75% D2O but the paused segmentation was recovered after rinse of D2O. In addition, we also observed that neuronal development of the Lymnaea stagnalis was reversibly inhibited by D2O (M. Sakakibara, unpublished data). However, mechanism of the toxicity of D2O and the effects of D2O on cellular events have not been fully understood. The spontaneous oscillation in cytosolic free Ca2+ concentration is one of the typical physiological events in living secretory cells. We previously demonstrated that the Ca2+ oscillations are regulated by voltage-sensitive Ca2+ channels (VSCC), Ca2+ ATPases, and Ca(2+)-induced Ca2+ release from intracellular stores. To analyze the site(s) of action of D2O in the living cellular systems, the present study examined effects of D2O on the Ca2+ mobilization and resting membrane potentials in AtT20 mouse pituitary cells.

AN - 70536924; 12697563 AB - We have reported that human interferon, one of cytokines present in serum, can confer hypomutability on various human cells. On the contrary, we have also reported that serum factors from cancer patients can enhance cell mutability. Therefore, it seems likely that cell mutability is changed by cytokine-like serum factors in our body. It is one of important space problems whether the mutability of human cells is regulated in response to microgravity and hypergravity (gravitational stress). However, there is little information about cell mutability during such stress. In this study, we investigated whether the mutability is changed by exposing cells to human serum factors after gravitational stress.

AN - 70534828; 12697566 AB - Mechanisms of molecular responses of human cells to gravity change and/or space radiation are one of the most important physiological problems in space science. We have previously reported that expression levels of several genes are changed in cultured human cells after UVC irradiation, and a few of those genes are responsible for UVC sensitivity. In this study, to find candidates for genes that play roles in susceptibility of human cells to gravity stressors, including those responsible for genetic stability in humans, we analyzed genes expressed differentially after gravity stress in human cells, using a PCR-based mRNA differential display (D.D.) method.

An ash layer from the top of the section has a U-Pb zircon age of 742+ or -6 Ma. The Chuar Group was deposited at low latitudes during extension on the north-trending Butte fault system and is inferred to record rifting during the breakup of Rodinia. Shallow-marine deposition is documented by tide- and wave-generated sedimentary structures, facies associations, and fossils. C isotopes in organic carbon show large stratigraphic variations, apparently recording incipient stages of the marked C isotopic fluctuations that characterize later Neoproterozoic time. Upper Chuar rocks preserve a rich biota that includes not only cyanobacteria and algae, but also heterotrophic protists that document increased food web complexity in Neoproterozoic ecosystems. The Chuar Group thus provides a well-dated, high-resolution record of early events in the sequence of linked tectonic, biogeochemical, environmental, and biological changes that collectively ushered in the Phanerozoic Eon.

Freezing rate would balance the sublimation rate from the top of the ice cover. Using heat transfer models from ice-covered Antarctic dry-valley lakes, tropical ice cover during Neoproterozoic is projected to have a thickness of 10 m or less. Transmissivity would be > 0.1% and would be sufficient for photosynthesis. (Mod. auth. abstr.)

The presented model is based on Rayleigh convection of interstitial water driven by an unstable density/temperature gradient within a saturated, porous medium. Catastrophic emplacement of water-rich sediments into the Martian northern plain basins could have provided a thick sedimentary layer in which Rayleigh convection could have occurred. Convection within this active layer is proposed to have differentially thawed an underlying ice-rich permafrost layer that had been at the planet's surface before being rapidly buried. The resulting morphology of the permafrost subsurface is thought to have resembled the scalloped solid-liquid interface morphology produced in terrestrial convective flow visualization studies. The exact size and shape of the scallops on the frozen subsurface would have been controlled by the dimensions of the convection cells, which are estimated to have had width-to-depth ratios of between 3.4 and 4.5. Subsequent stresses (e.g., gravity and bending stresses) would have produced maximum tensile stresses in the overlying sediments preferentially above the subsurface topographic highs as described previously by McGill and Hills [1992]. Additional desiccation of the sediments would have required contraction of the sediment cover and would have produced large-scale polygonal fractures along the preexisting weaknesses located above the raised subsurface topography. Thus the underlying subsurface geometric morphology would have been translated to the surface and would be represented by the large-scale polygonal fractures visible in the Viking Orbiter and Mars Global Surveyor images of the Martian northern plains.

This idea is applied to observations and analysis of sea surface slopes as inferred using optical and microwave-scattering measurements. Our study emphasizes the importance of identifying and quantifying the distribution variance and kurtosis from observations. Data are shown to indicate consistently non-Gaussian peakedness, to indicate the need to report at least two parameters in an even order analysis, and to indicate near equivalence between radar and optical data. Physical interpretation for observed infrequent steep slopes is given via compounding statistical processes where normally distributed short-scale waves are modulated because of random fluctuations mainly associated with the underlying long wave field. Implications of non-Gaussian peakedness are provided for altimeter backscatter theory and for modeling wave-breaking probability. Copyright 2000 by the American Geophysical Union.

The observations show not only the appearance of a dipole mode in the tropical region but also a persistent basin-scale warming. We present in this study an analysis of the basin-scale sea surface temperature (SST) variations during 1997-1998 using satellite observations, in situ temperature measurements, and National Centers for Environmental Prediction reanalyses. We find that the Indian SST anomaly peaks occurred at two periods, i.e., November-December-January coinciding with the Nino3 peak and the following April-May-June, and were phase locked to the Indian Ocean seasonal cycle. The changes of SST in the equatorial ocean were related to a coupled interaction between the atmosphere and the ocean. Oceanic upwelling in the east and downwelling in the west played a major role in giving rise to the SST anomalies associated with the dipole mode structure. The upwelling off the coast of Sumatra elevated the regional thermocline by more than 80 m in December 1997. On the other hand, the changes of SST in the southern Indian Ocean were largely induced by the changes of local latent flux. During boreal fall-winter of 1997 the southeasterly trades were displaced and abnormally prolonged in their northernmost equatorial position. This shifted the center of the trades toward the equator, weakened the winds in the central Southern Ocean, reduced the latent heat flux in the region, and subsequently induced a surface warming. The total change of the SST anomalies integrated over the two periods, July-December 1997 and January-May 1998, were explained well by the same period latent flux integral in both intensity and pattern. The cross-basin upper ocean temperature sections show that the extratropical warming was rather uniformly distributed in the upper 60 m, further supporting the role of mixed-layer processes in the warming.

Chicken skeletal muscle cells were treated with 1 mu M isoproterenol, a strong beta AR agonist, between days 7 and 10 in culture. beta AR population increased by approximately 40% during this treatment; however, the ability of the cells to synthesize cyclic adenosine monophosphate (cAMP) was diminished by twofold. Neither the basal concentration of cAMP nor the quantity of myosin heavy chain (MHC) was affected by the 3-d exposure to isoproterenol. To understand further the relationship between intracellular cAMP levels, beta AR population, and muscle protein accumulation, intracellular cAMP levels were artificially elevated by treatment with 0-10 mu M forskolin for 3 d. The basal concentration of cAMP in forskolin-treated cells increased up to sevenfold in a dose-dependent manner. Increasing concentrations of forskolin also led to an increase in beta AR population, with a maximum increase of approximately 40-60% at 10 mu M forskolin. A maximum increase of 40-50% in the quantity of MHC was observed at 0.2 mu M forskolin, but higher concentrations of forskolin reduced the quantity of MHC back to control levels. At 0.2 mu M forskolin, intracellular levels of cAMP were higher by approximately 35%, and the beta AR population was higher by approximately 30%. Neither the number of muscle nuclei fused into myotubes nor the percentage of nuclei in myotubes was affected by forskolin at any of the concentrations studied.

Gall formation has been described previously on two species of Prionitis, P. lanceolata (from central California) and P. decipiens (from Peru). This investigation reports gall formation on a third related host, Prionitis filiformis. Phylogenetic analyses based on sequence comparisons place the bacteria as a single lineage within the Roseobacter grouping of the alpha subclass of the division Proteobacteria (99.4 to 98.25% sequence identity among phylotypes). Comparison of symbiont and host molecular phylogenies confirms the presence of three gall-bearing algal lineages and is consistent with the hypothesis that these red seaweeds and their bacterial symbionts are coevolving. The species specificity of these associations was investigated in nature by whole-cell hybridization of gall bacteria and in the laboratory by using cross-inoculation trials. Whole-cell in situ hybridization confirmed that a single bacterial symbiont phylotype is present in galls on each host. In laboratory trials, bacterial symbionts were incapable of inducing galls on alternate hosts (including two non-gall-bearing species). Symbiont-host specificity in Prionitis gall formation indicates an effective ecological separation between these closely related symbiont phylotypes and provides an example of a biological context in which to consider the organismic significance of 16S rDNA sequence variation.

AN - 85353346; pmid-10958400 AB - This study combined ultrastructural and statistical methods to learn the effects of weightlessness on rat utricular maculae. A principle aim was to determine whether weightlessness chiefly affects ribbon synapses of type II cells, since the cells communicate predominantly with branches of primary vestibular afferent endings. Maculae were microdissected from flight and ground control rat inner ears collected on day 13 of a 14-day spaceflight (F13), landing day (R0) and day 14 postflight (R14) and were prepared for ultrastructural study. Ribbon synapses were counted in hair cells examined in a Zeiss 902 transmission electron microscope. Significance of synaptic mean differences was determined for all hair cells contained within 100 section series, and for a subset of complete hair cells, using SuperANOVA software. The synaptic mean for all type II hair cells of F13 flight rats increased by 100%, and that for complete cells by 200%. Type I cells were less affected, with synaptic mean differences statistically insignificant in complete cells. Synapse deletion began within 8 h upon return to Earth. Additionally, hair cell laminated rough endoplasmic reticulum of flight rats was reversibly disorganized on R0. Results support the thesis that synapses in type II hair cells are uniquely affected by altered gravity. Type II hair cells may be chiefly sensors of gravitational and type I cells of translational linear accelerations.

AN - 72490859; 11543508 AB - In order to simulate prebiotic synthetic processes on Europa and other ice-covered planets and satellites, we have investigated the prebiotic synthesis of organic compounds from dilute solutions of NH4CN frozen for 25 years at -20 and -78 degrees C. In addition, the aqueous products of spark discharge reactions from a reducing atmosphere were frozen for 5 years at -20 degrees C. We find that both adenine and guanine, as well as a simple set of amino acids dominated by glycine, are produced in substantial yields under these conditions. These results indicate that some of the key components necessary for the origin of life may have been available on Europa throughout its history and suggest that the circumstellar zone where life might arise may be wider than previously thought.

AN - 72490735; 11543484 AB - To observe renal damage due to acute hypobaric hypoxia. Thirty-six male wistar rats were randomly divided into three groups A, B and C (n = 12 for each). Group A served as control, while groups B and C were exposed to 5000 m altitude for 30 min. Sample of serum and renal tissues were taken from group B rats 20 min and from group C rats 24 h after the exposure respectively. Serum ureanitrogen (BUN) and creatinine (Crea) increased significantly in group B and C rats after exposure to hypoxia (P< 0.01). Cl- and alkaline phosphatase (AKP) in serum also increased (P < 0.05), but renal endothelin (ET) decreased significantly (P < 0.01). All changes in group C rats tended to recover to normal level, except Cl- which continued to increase. Dilation of renal vessels was found under optic-microscope, and pathological changes were found in mitochondra and epithelial cells.

AN - 72487205; 11543483 AB - In order to provide reference for controlling and monitoring the environmental contamination in the spacecraft, the species and amount of microbes, which adhere to the suspended particles with different size in a closed environment were detected. According to USA EPA IP-10, particles were continuously sampled by an impactor in a closed environment. The particles were divided into three grades by their aerodynamic diameters (AD): 100 micrometers > or = AD > 10 micrometers, 10 micrometers > or = AD>2 micrometers and AD < or = 2 micrometers. Clean outdoor air was collected as control by the same way. The collected particles were precisely weighed. The microbes that adhere to the particles were cultivated, counted and identified. By calculating total suspended particles (TSP) and inhalant particles (IP) of the closed environment, counting, clarifying and identifying the microbes, 6 kinds of bacteria, 2 genus of actinomyces and 6 kinds of fungi that adhere to the particles were detected. The particles in a closed environment may have some effect on human health and instruments.

AN - 72483914; 11543286 AB - A hundred years of research has not produced a clear understanding of the mechanism that transduces the energy associated with the sedimentation of starch-filled amyloplast statoliths in root cap columella cells into a growth response. Most models postulate that the statoliths interact with microfilaments (MF) to transmit signals to the plasma membrane (or ER), or that sedimentation onto these organelles produces the signals. However, no direct evidence for statolith-MF links has been reported, and no asymmetric structures of columella cells have been identified that might explain how a root turned by 90 degrees knows which side is up. To address these and other questions, we have (1) quantitatively examined the effects of microgravity on the size, number, and spatial distribution of statoliths; (2) re-evaluated the ultrastructure of columella cells in high-pressure frozen/freeze-substituted roots; and (3) followed the sedimentation dynamics of statolith movements in reoriented root tips. The findings have led to the formulation of a new model for the gravity-sensing apparatus of roots, which envisages the cytoplasm pervaded by an actin-based cytoskeletal network. This network is denser in the ER-devoid central region of the cell than in the ER-rich cell cortex and is coupled to receptors in the plasma membrane. Statolith sedimentation is postulated to disrupt the network and its links to receptors in some regions of the cell cortex, while allowing them to reform in other regions and thereby produce a directional signal.

AN - 72479286; 11543368 AB - We compare models of radiation transport and biological response to physical and biological dosimetry results from astronauts on the Mir space station. Transport models are shown to be in good agreement with physical measurements and indicate that the ratio of equivalent dose from the Galactic Cosmic Rays (GCR) to protons is about 3/2:1 and that this ratio will increase for exposures to internal organs. Two biological response models are used to compare to the Mir biodosimetry for chromosome aberration in lymphocyte cells; a track-structure model and the linear-quadratic model with linear energy transfer (LET) dependent weighting coefficients. These models are fit to in vitro data for aberration formation in human lymphocytes by photons and charged particles. Both models are found to be in reasonable agreement with data for aberrations in lymphocytes of Mir crew members: however there are differences between the use of LET dependent weighting factors and track structure models for assigning radiation quality factors. The major difference in the models is the increased effectiveness predicted by the track model for low charge and energy ions with LET near 10 keV/micrometers. The results of our calculations indicate that aluminum shielding, although providing important mitigation of the effects of trapped radiation, provides no protective effect from the galactic cosmic rays (GCR) in low-earth orbit (LEO) using either equivalent dose or the number of chromosome aberrations as a measure until about 100 g/cm 2 of material is used.

AN - 72476137; 11543369 AB - The efficiency of 7 LiF TLDs (TLD-700) in registering dose from high-LET (> or = 10 keV/micrometers) charged particles (relative to 137Cs gamma rays) has been measured for a number of accelerated heavy ions at various particle accelerator facilities. These measured efficiency values have been compared with similar results obtained from the open literature and a dose efficiency function has been fitted to the combined data set. While it was found that the dose efficiency is not only a function of LET, but also of the charge of the incident particle, the fitted function can be used to correct the undermeasured value of dose from exposures made in mixed radiation fields where LET information is available. This LET-dependent dose efficiency function is used in our laboratory in determining total absorbed dose and dose equivalent from combined TLD and CR-39 plastic nuclear track detector measurements.

AN - 72473567; 11543277 AB - Some of the most extreme environments where animals survive are associated with active vents and seeps in the deep sea. In addition to the extreme pressure, low temperatures, and lack of light that characterize the deep sea in general, a variety of other factors that are hostile to most animals prevail in these environments. Hydrothermal vent regions show extremes in temperature, areas of very low oxygen, and the presence of toxic hydrogen sulfide and heavy metals. Hydrocarbon seeps, though much cooler than vents, also have regions of very low oxygen and high hydrogen sulfide, as well as other potentially harmful substances such as crude oil and supersaturated brine. Specially adapted animals not only tolerate these conditions, they often thrive under them. In most cases this tolerance is due to a combination of physiological and behavioral adaptations that allow animals to avoid the extremes of their habitats and yet benefit from the chemoautotrophic production characteristic of these environments.

AN - 71262738; 10929379 AB - DNA double-strand breaks (DSBs) produced by densely ionizing radiation are not located randomly in the genome: recent data indicate DSB clustering along chromosomes. Stochastic DSB clustering at large scales, from > 100 Mbp down to < 0.01 Mbp, is modeled using computer simulations and analytic equations. A random-walk, coarse-grained polymer model for chromatin is combined with a simple track structure model in Monte Carlo software called DNAbreak and is applied to data on alpha-particle irradiation of V-79 cells. The chromatin model neglects molecular details but systematically incorporates an increase in average spatial separation between two DNA loci as the number of base-pairs between the loci increases. Fragment-size distributions obtained using DNAbreak match data on large fragments about as well as distributions previously obtained with a less mechanistic approach. Dose-response relations, linear at small doses of high linear energy transfer (LET) radiation, are obtained. They are found to be non-linear when the dose becomes so large that there is a significant probability of overlapping or close juxtaposition, along one chromosome, for different DSB clusters from different tracks. The non-linearity is more evident for large fragments than for small. The DNAbreak results furnish an example of the RLC (randomly located clusters) analytic formalism, which generalizes the broken-stick fragment-size distribution of the random-breakage model that is often applied to low-LET data.

AN - 71211103; 10870820 AB - Previous studies show that an ambient CO2 concentration of 2.0% may complicate interpretation of animal experiments conducted in spaceflight, while 0.7% CO2 exposure produces minimal effects. With additional spaceflight factors, such as microgravity, effects from the 0.7% CO2 exposure may be amplified. To investigate the combined effects from microgravity and elevated CO2 on growth and renal function, two groups of rats were hindlimb suspended for 37 d, and a third group served as an ambulatory vivarium control (AMB). One suspension group was exposed to 0.7% CO2 for 30 d (HLS + 0.7% CO2), while the other group (HLS) served as a suspended control. Both the AMB and HLS groups breathed room air at 0.03% CO2. The HLS group showed responses consistent with past hindlimb suspension studies when compared with AMB, indicating similar reductions in organ and tissue weights and body weight gain. When comparing HLS + 0.7% CO2 animals to HLS controls, exposure to CO2 revealed lowered food consumption and increased urine volume, NH3 and CO2 excretion, with no differences in any of the other measured parameters, such as body weight gain, pH values, or electrolyte handling. This study shows that chronic exposure to both 0.7% ambient CO2 and hindlimb suspension together have little additional effect on rat growth and renal function.

AN - 71210285; 10870819 AB - In experiments using rodents onboard orbiting spacecraft, specimens may be exposed to an increase in ambient CO2. Many of the physiological changes reported in rats (and humans) for spaceflight are similar to those observed with increased CO2, raising the question whether the observed changes are due to spaceflight or more specifically, the elevated ambient CO2. To evaluate the effects of increased CO2, at levels similar to those experienced during spaceflight, three groups of adult male rats (n = 10) were exposed to ambient CO2 concentrations of 0.3, 0.7 and 2.0% for 30 d. Control rats were exposed to atmospheric conditions (0.03% CO2) for each group. There were alterations in water turnover, food intake, and renal function with increased CO2. Blood pH, total CO2, and plasma concentrations of Na+, Ca2+, and corticosterone were significantly elevated at the 2.0% exposure, while plasma PO4(3-) was reduced. At the 0.3% and 0.7% CO2 exposures, many of these changes were not significant. Animals exposed to 0.3% CO2 showed a significant increase in total body Na+. Urinary Ca2+, K+, creatinine, corticosterone, and total CO2 excretion were higher at 2.0%, but only Ca2+ and CO2 excretion were significantly elevated at 0.7%, and there was no significant alteration in renal function at 0.3%. Chronic increased ambient CO2 levels, similar to those observed on the Space Shuttle and proposed for the International Space Station, elicit compensatory responses in rats which may affect interpretation of experiments designed to evaluate the effects of exposure to microgravity.

Published isotopic ages of silicate from other IIE meteorites are discussed. The meteorite Watson has an Ar-Ar isotopic age of 3677 + or - 7 m.y. similar to previous reported ages for Kodaikanal and Netschaevo meteorites, and it is suggested that these ages were reset by a common impact. Ar-Ar isotopic ages for the other four meteorites are: Techado 4490 + or - 10 m.y., Miles 4405 + or - 12 m.y., Colomera 4470 + or - 10 m.y. and Sombrerete 4541 + or - 12 m.y., these ages are similar to those previously found for Colomera and Weekeroo Station meteorites. Those IIE meteorites with older isotopic ages are, it is suggested a product of partial melting and differentiation within the parent body followed by mixing of silicate and metal.

The transmittance spectra showed a distinct dependence on the mode of sample preparation: measurements taken on pellets prepared by pressing the sample with alkali halides (KBr or CsI) displayed bands at 1096, 1050, and 698 cm (super -1) that were not observed in spectra of the neat material and must therefore be considered artifacts. Variations in the sampling environment (e.g., water and/or organic volatiles) were also observed to exert a noticeable influence on the development of the IR spectra. Infrared bands due to akaganeite were found at 3480+3390 (doublet) 1630, 850+820 (doublet), 650, 490, and approximately 420 cm (super -1) . Diffuse reflectance spectra dominated by volume scattering (loose), diffuse reflectance spectra comprised of both volume and surface scattering (compacted), ATR spectra (surface only), and transmittance spectra (absorbance only, inverse of ATR) showed compatible trends for the akaganeite features both above and below approximately 1000 cm (super -1) . This indicates that the multiple akaganeite measurements are consistent and confirms the band assignments.

The lake water has a low conductivity and is relatively well mixed. Sediments are transferred from the adjacent glacier to the lake when glacier ice surrounding the sediment is subliminated at the surface and replaced by accumulating ice from below. The lake bottom at the west end of the lake is mostly rocky with a scant sediment cover. The east contains a thick sediment profile. Grain size and delta (super 13) C increase with sediment depth, indicating a more proximal glacier in the past. Sedimentary (super 210) Pb and (super 137) Cs signals are exceptionally strong, probably a result of the focusing effect of the large glacial catchment area. The post-bomb and pre-bomb radiocarbon reservoirs are c. 725 (super 14) C yr and c. 1950 (super 14) C yr, respectively. Radiocarbon dating indicates that the east end of the lake is 3 ka BP, while photographic evidence and the absence of sediment cover indicate that the west end has formed only over the last century. Our results indicate that the southern ice edge of Bunger Hills has been relatively stable with only minor fluctuations (on the scale of hundreds of metres) over the last 3000 years.

The procedures include (1) coregistration of backscatter intensity images to observe morphological differences; (2) mapping of interferometric phase correlation to identify preserved and modified surfaces; and (3) construction, correction, and differencing of pre-joekulhlaup and post-joekulhlaup topography. Procedures 1 and 2 are robust and should be widely applicable to other fluvial environments, while procedure 3 is complicated by uncertainties in phase measurement, baseline estimate, and atmospheric effects. After a correction procedure involving interpolation of digital elevation model elevation differences across low-correlation areas, we find approximately 4 m of elevation change are required to calculate volumes of erosion or deposition. This condition was satisfied for the 40 km (super 2) proglacial zone of Skeidararsandur, where we estimate +38 X 10 (super 6) m (super 3) of net sediment deposition along the ice margin, -25 X 10 (super 6) m (super 3) of net erosion in channels downstream, and a total net balance of +13 X 10 (super 6) .

Any global mission, like SeaWiFS, requires validation data from a wide variety of investigators. This places a significant challenge on quantifying the total uncertainty associated with the in situ measurements, because each investigator follows slightly different practices when it comes to implementing all of the steps associated with collecting field data, even those with a prescribed set of protocols. This study uses data from multiple cruises to quantify the uncertainties associated with implementing data collection procedures while using different in-water optical instruments and deployment methods. A comprehensive approach is undertaken and includes (a) the use of a portable light source and in-water intercomparisons to monitor the stability of the field radiometers, (b) alternative methods for acquiring reference measurements, and (c) different techniques for making in-water profiles. Three optical systems had quadrature sum uncertainties sufficiently small to ensure a combined uncertainty for the spaceborne and in situ measurements within a total 5% vicarious calibration budget. A free-fall profiler using (relatively inexpensive) modular components performed best (2.7% quadrature sum uncertainty), although a more sophisticated (and comparatively expensive) profiler using integral components was very close and only 0.5% higher. A relatively inexpensive system deployed with a winch and crane was also close, but ship shadow contamination increased the quadrature sum uncertainty to approximately 3.4%.

Human MIP-101 poorly differentiated colorectal carcinoma cells were cultured for 6 d in complete medium in monolayers, on Teflon registered -coated nonadherent surfaces (static three-dimensional [3D]) or in rotating 3D cultures either in microgravity in low-earth orbit (3D mu g) or in unit gravity on the ground (3D 1g). Apoptosis (determined morphologically), proliferation (by MIB1 staining), and the expression of epidermal growth-factor receptor (EGF-R), TGF- alpha , or TGF- beta were assessed by immunohistochemistry, while the expression of the differentiation marker carcinoembryonic antigen (CEA) was assessed on Western blots. Over the course of 6 d, static 3D cultures displayed the highest rates of proliferation and lowest apoptosis. This was associated with high EGF-R, TGF- alpha , and TGF- beta expression which was greater than that of a monolayer culture. Both rotated 3D 1g and 3D mu g cultures displayed lower expression of EGF-R, TGF- alpha , or TGF- beta and proliferation than that of monolayer or static 3D cultures. However, rotated 3D mu g displayed significantly less apoptosis and greater CEA expression than rotated 3D 1g cultures. When rotated cultures of MIP-101 cells were grown under static conditions for another 3 d, proliferation increased and apoptosis decreased. Thus, rotation appears to increase apoptosis and decrease proliferation, whereas static 3D cultures in either unit or microgravity have less apoptosis, and reduced rotation in microgravity increases CEA expression.

Hypotheses that elevated CO sub(2) pressure and air temperature would alter leaf optical properties were tested for sugar maple (Acer saccharum) in the middle of its fourth growing season under treatment. The saplings had been growing since 1994 in open-top chambers and partial shade at Oak Ridge, Tennessee under the following treatments: (1) ambient CO sub(2) pressure and air temperature (control); (2) CO sub(2) pressure approximately 30 Pa above ambient; (3) air temperatures 3 degree C above ambient; and (4) elevated CO sub(2) and air temperature. Under elevated CO sub(2) or temperature, spectral reflectance, transmittance and absorptance in the visible spectrum (400-720 nm) tended to change in patterns that generally are associated with chlorosis, with maximum differences from the control near 700 nm. However, these changes were not significant at P = 0.05. Although reflectance, transmittance and absorptance at 700 nm correlated strongly with leaf chlorophyll concentration, variability in chlorophyll concentration was greater within than among treatments. The lack of treatment effects on pigmentation explained the non-significant change in optical properties in the visible spectrum. Optical properties in the near-infrared (721-850 nm) were similarly unresponsive to treatment with the exception of an increased absorptance throughout the 739-850 nm range in leaves that developed under elevated air temperature alone. This response might have resulted from effects of air temperature on leaf internal structure.

The fact that denitrification occurs in a relatively warm month in the Antarctic raises concern about the likelihood of its occurrence and associated effects on ozone recovery in a colder and possibly more humid future Arctic lower stratosphere. Polar stratospheric cloud lifetimes required for Arctic denitrification to occur in the future are presented and contrasted against the current Antarctic cloud lifetimes. Model calculations show that widespread severe denitrification could enhance future Arctic ozone loss by up to 30%.

AIR 2000 Annual Forum Paper. AN - 62318403; ED446514 AB - This study investigated how economically and sociologically underprivileged students readied themselves for college, highlighting factors affecting the lowest socioeconomic status (SES) students' chances to: secure college qualifications, graduate from high school, and apply to four-year institutions. Data from the 1998 National Educational Longitudinal Study were used to examine the three tasks. A model was developed to portray the college choice process as the by-product of interrelated influences beginning in 8th grade and continuing until college enrollment. The influences included: academic ability, amount and quality of parental involvement/encouragement, early educational and occupational aspirations, acquisition of college qualifications, and availability of information about college. Most of the lowest SES 8th graders had parents with no college experience and were exposed to factors placing them at risk of dropping out of high school. About 81 percent of 8th graders who completed the three tasks enrolled in college by 1994. Securing college qualifications correlated with SES, with the lowest SES students least likely to secure minimal qualifications. Parental involvement, early planning for college, and experiencing at-risk factors most affected students' chances of becoming college qualified. Rate of graduation from high school correlated and college application rates varied in direct relation to SES. (Contains 61 references.) (SM) AU - Cabrera, Alberto F. AU - La Nasa, Steven M.

Aerosol pollution is expected to exert a net cooling influence on the global climate through these conventional mechanisms. Here, we demonstrate an opposite mechanism through which aerosols can reduce cloud cover and thus significantly offset aerosol-induced radiative cooling at the top of the atmosphere on a regional scale. In model simulations, the daytime clearing of trade cumulus is hastened and intensified by solar heating in dark haze (as found over much of the northern Indian Ocean during the northeast monsoon).

AN - 72489515; 11543516 AB - We have investigated the effects induced by ion bombardment of mixtures containing nitrogen-bearing compounds at low temperatures. The results show the formation of a band at 2080 cm-1 in binary mixtures, NH3:CH4 and N2:CH4, which we attribute to HCN embedded in the organic residue formed by ion irradiation. In addition to this band, ternary mixtures containing an oxygen-bearing species (i.e., H2O) form a compound with a prominent absorption band at about 2165 cm-1 (4.62 microns). We ascribe this band to a nitrile compound containing O that is bonded to the organic residue. A detailed comparison of the laboratory results with astronomical data of the 4.62 microns absorption band in protostellar spectra shows good agreement in peak position and profile. Our experimental studies show that N2, which is a more likely interstellar ice component than NH3, can be the molecular progenitor of the carrier of the interstellar band. This is an alternative to the pathway by which UV photolysis of NH3-containing ices produces the 4.62 microns band and implies that ion bombardment may well play an important role in the evolution of interstellar ices.

AN - 72476087; 11543411 AB - Although the germicidal action of sunlight has long been recognized, its potential for practical applications has to be researched more thoroughly. This paper summarizes the progress made toward a commercially practical collector for solar disinfection applications. Nontracking compound parabolic collectors (CPCs), developed originally for capturing solar photons for thermal energy applications, were examined as potential solar photoreactors. A field demonstration of solar disinfection treatment using commercially manufactured solar reactors was conducted. Field tests showed successful destruction of Escherichia coli and Enterococcus faecalis and have provided data for full-scale design of water treatment systems. From above observations, a throughput value of 50 L/m2 h for the low-cost CPC reactor tested was estimated. For a 190 m3/d (0.05 MGD) facility, the estimated total costs for disinfection using UV-A is U.S. $0.19/m3 ($0.70/1000 gal). The use of near-UV sunlight to disinfect water supplies seems promising in rural communities of developing countries where treated water is unavailable.

AN - 70527812; 11963958 AB - Laser ablation arrays of triangular and square shaped clusters, comprised of 23 micrometers diam circular holes, are defined upon 100 nm thick Ni81Fe19 films used to control the rf permeability spectra. Cluster-to-cluster spacing is varied from 200 to 600 micrometers. For each geometry it is found that the loss peak frequency and permeability magnitude shift lower, in a step-wise fashion, at a cluster-to-cluster spacing between 275 and 300 micrometers. The nonlinear shift in the behavior of the permeability spectra correlates with a dramatic increase in domain wall density. c2000 American Institute of Physics.

AN - 70521598; 11963959 AB - Ribbonlike magnetoelastic sensors can be considered the magnetic analog of an acoustic bell; in response to an externally applied magnetic field impulse the sensors emit magnetic flux with a characteristic resonant frequency. The magnetic flux can be detected external to the test area using a pick-up coil, enabling query remote monitoring of the sensor. The characteristic resonant frequency of a magnetoelastic sensor changes in response to mass loads. [L.D. Landau and E. M. Lifshitz, Theory of Elasticity, 3rd ed. (Pergamon, New York, 1986). p. 100].Therefore, remote query chemical sensors can be fabricated by combining the magnetoelastic sensors with a mass changing, chemically responsive layer. In this work magnetoelastic sensors are coated with humidity-sensitive thin films of ceramic, nanodimensionally porous TiO2 to make remote query humidity sensors. c2000 American Institute of Physics.

The supersaturated solutions (pH nearly equal 6-7) were prepared at room temperature and contained in Teflon (super TM) -lined stainless steel vessels, which were sealed and heated to 150 degrees C for 24 h. Experiments were also conducted at 25 degrees C and no globules comparable to those of ALH 84001 were precipitated. Instead, amorphous Fe-rich carbonates were formed after 24 h and Mg-Fe calcites formed after 96 h. These experiments suggest a possible low-temperature inorganic origin for the carbonates in martian meteorite ALH 84001.

Consequently, the validation of these records is important in meteorite research. The first step in the validation process should be the REM value. The REM value is the ratio of natural remanence (NRM) to saturation remanent magnetization imparted by a 1 T magnetic field (SIRM). The REM values range over 3 to 4 orders of magnitude for stony meteorites and for chondrules from Allende (C3V-S1), Bjurbole (L4-S1), and Chainpur (LL3-S1) meteorites. The REM values computed from published NRM and SIRM data identify many orders of magnitude range in the REM values including REM values >100 X 10 (super -3) . These data suggest a dependence for the NRM intensity on the curatorial location from which the sample was obtained. Any earth rock acquiring thermoremanent magnetization (TRM) in the geomagnetic field has a restricted range in REM mostly between 5 and 50 X 10 (super -3) , the exception being the mineral hematite in the multidomain size range. The only terrestrial samples with REM much greater than 100 X 10 (super -3) are those struck by lightning. The REM value provides a physical basis for recognition between valid records and those that "might be contaminated." The isothermal remanence acquisition (RA) curve is presented as a contamination curve that allows an indication of the level of magnetic field contamination required to give the computed "REM" (RM/SIRM) value. In the case of the Bjurbole and Chainpur chondrules, with REM values >100 X 10 (super -3) , the RA curve indicates that unrealistically large contamination magnetic fields would be required to give REM values greater than 100 X 10 (super -3) . This would suggest contamination other than by a hand magnet that is normally available to an experimenter. This would require an explanation that would involve large magnetic fields during chondrule formation, or some extraordinary remanence acquisition mechanism that remains to be described. Magnetic contamination experiments, using approximately 80 and approximately 40 mT magnets, demonstrate that the "REM" values and extent of modification of the magnetic vector record are mineralogy dependent, and this is mostly related to the amount and characteristics of the mineral tetrataenite. The complexity of the meteorite records suggest validation of the record as a first step. The REM value is the first physical statement that can be made in this validation.

Ophitic/subophitic clasts fall into two groups: finer-grained lithology A and coarser-grained lithology B. Very fine-grained clasts with equigranular textures (lithology C) also occur and originally were hypocrystalline in texture. The variety of materials represented in Piplia Kalan suggests cooling histories ranging from quenching to slower crystallization. Despite textural differences, clasts and matrix have similar mineral and bulk compositions. Thus, Piplia Kalan is probably best classified as a genomict breccia that could represent fragments of a single lava flow or shallow intrusive body, including fine-grained or glassy outer margin and more slowly cooled coarser-grained interior. Bulk composition suggests that the meteorite is most closely related to the main group eucrites, but it probably was affected by minor amounts of fractional crystallization. Piplia Kalan displays evidence of an early shock event, including brecciated matrix and areas of lithic clasts that contain very fine-grained, granular pyroxene between deformed feldspar laths. The meteorite also displays evidence of at least one episode of extensive thermal metamorphism: hypocrystalline materials are recrystallized to hornfelsic textures and minerals throughout the meteorite contain abundant inclusions that are relatively large in size. Veins of brown glass transect both clasts and matrix and indicate a second, postmetamorphism shock event.

The algorithm has the same functional form as the NASA Team algorithm, but uses a wider range of frequencies (19-85 GHz). It accommodates ice temperature variability through the use of radiance ratios as in the original NASA Team algorithm, and has the added advantage of providing weather-corrected sea ice concentrations through the utilization of a forward atmospheric radiative transfer model. Retrievals of sea ice concentration with this new algorithm for both the Arctic and Antarctic do not reveal the deficiencies present in either the NASA Team or Bootstrap algorithms. Furthermore, quantitative comparisons with infrared AVHRR data show that the enhanced algorithm provides more accurate ice concentrations with much less bias than the other two algorithms.

AN - 51210597; 2000-048831 AB - Petrographic and geochemical analyses of travertine-depositing hot springs at Angel Terrace, Mammoth Hot Springs, Yellowstone National Park, have been used to define five depositional facies along the spring drainage system. Spring waters are expelled in the vent facies at 71 to 73 degrees C and precipitate mounded travertine composed of aragonite needle botryoids. The apron and channel facies (43-72 degrees C) is floored by hollow tubes composed of aragonite needle botryoids that encrust sulfide-oxidizing Aquificales bacteria. The travertine of the pond facies (30-62 degrees C) varies in composition from aragonite needle shrubs formed at higher temperatures to ridged networks of calcite and aragonite at lower temperatures. Calcite "ice sheets", calcified bubbles, and aggregates of aragonite needles ("fuzzy dumbbells") precipitate at the air-water interface and settle to pond floors. The proximal-slope facies (28-54 degrees C), which forms the margins of terracette pools, is composed of arcuate aragonite needle shrubs that create small microterracettes on the steep slope face. Finally, the distal-slope facies (28-30 degrees C) is composed of calcite spherules and calcite "feather" crystals. Despite the presence of abundant microbial mat communities and their observed role in providing substrates for mineralization, the compositions of spring-water and travertine predominantly reflect abiotic physical and chemical processes. Vigorous CO (sub 2) degassing causes a +2 unit increase in spring water pH, as well as Rayleigh-type covariations between the concentration of dissolved inorganic carbon and corresponding delta (super 13) C. Travertine delta (super 13) C and delta (super 18) O are nearly equivalent to aragonite and calcite equilibrium values calculated from spring water in the higher-temperature ( approximately 50-73 degrees C) depositional facies. Conversely, travertine precipitating in the lower-temperature (< approximately 50 degrees C) depositional facies exhibits delta (super 13) C and delta (super 18) O values that are as much as 4 per mil less than predicted equilibrium values. This isotopic shift may record microbial respiration as well as downstream transport of travertine crystals. Despite the production of H (sub 2) S and the abundance of sulfide-oxidizing microbes, preliminary delta (super 34) S data do not uniquely define the microbial metabolic pathways present in the spring system. This suggests that the high extent of CO (sub 2) degassing and large open-system solute reservoir in these thermal systems overwhelm biological controls on travertine crystal chemistry.

AN - 50300523; 2000-054256 AB - Crustal magnetic anomalies are the result of adjacent geologic units having contrasting magnetization. This magnetization arises from induction and/or remanence. In a planetary context we now know that Mars has significant crustal magnetic anomalies due to remanent magnetization, while on the Earth both remanence and induction can contribute to the magnetic anomaly, because of the presence of the Earth"s magnetic field. If there is a significant induced magnetization (IM) then magnetite is commonly assumed as the source, since it has a much greater magnetic susceptibility, when compared with other magnetic minerals. We investigated the thermoremanent magnetization (TRM) acquisition of hematite to determine if the remanent and induced magnetization of hematite could compete with magnetite in weak magnetic fields up to 1 mT. TRM acquisition curves of magnetite and hematite show that multidomain hematite approaches TRM saturation (0.3-0.4 A m (super 2) /kg) in fields as low as 0.1 mT. However, multidomain magnetite reaches only a few percent of its TRM saturation in a field of 0.1 mT (0.02-0.06 A m (super 2) /kg). These results suggest that a mineral such as multidomain hematite and, perhaps, other minerals with significant remanence and minor induced magnetization may play an important role in providing requisite magnetization contrast. Consequently, we should reevaluate where multidomain hematite exists in significant concentration, allowing a better insight into the role of remanent magnetization in the interpretation of the magnetic anomalies.

Magnetic exchange anisotropy is postulated to be characteristic of cation excess in some spinel titanomagnetites. The exchange anisotropy is characterized by loop shifting along the field and magnetization axes when cooled in a magnetic field, large coercivity increase, and magnetic viscosity which has discrete activation fields and logarithmic to linear decay characteristics. The cryogenic loop characteristics attributable to exchange anisotropy are not found in the tree-mold where iron and ilmenite are the main phases. The coupling has been created in the laboratory with ordinary basalt artificially reduced in Hydrogen gas. The coupling is not found in spinel oxidation non-stoichiometry. These results imply that we are able to identify the presence of spinels that have equilibrated in the low oxygen fugacity range of the spinel stability field where cation excess is characteristic.

Greenhouse warming by gaseous CO (sub 2) and H (sub 2) O by itself is in conflict with constraints on atmospheric CO (sub 2) levels derived from paleosols for early Earth. Here we explore whether greenhouse warming by methane could have been important. We find that a CH (sub 4) mixing ratio of 10 (super -4) (100 ppmv) or more in Earth's early atmosphere would provide agreement with the paleosol data from 2.8 Ga. Such a CH (sub 4) concentration could have been readily maintained by methanogenic bacteria, which are thought to have been an important component of the biota at that time.

[1983]. Separate calculations for low- and high-pass flow fields, distinguished by periods greater than and less than 6 months, respectively, are performed and revealed a fundamental difference between the eddy characteristics of the two. The areas with largest values of surface eddy kinetic energy occur in the vicinity of the Kuroshio Extension and the subtropical front. Near the Kuroshio Extension the low-pass surface eddy kinetic energy is greater than the high-pass energy, but in the subtropical frontal area the high-pass eddy flow accounts for more energy than the low-pass flow. For both areas the values of eddy kinetic energy are larger in summer than during winter. Low-pass eddy flow tends to be aligned zonally, and the high-pass eddy flow is aligned meridionally. Near the subtropical front the ratio of major to minor axis length is typically approximately 1.5:1, whereas near the Kuroshio Extension that ratio increases to values near 2:1. Along the southern boundary of the subtropical gyre the high-pass eddy flow tends to propagate eastward relative to the mean flow, tending to decrease the gyre strength. However, the low-pass eddy flow propagates westward relative to the mean flow and tends to increase the gyre strength. An additional computation of surface heat transport is used to deduce vertical propagation tendencies of the eddy flow and indicates that the low-pass flow field transports more heat than the high-pass flow with the largest eddy transports occurring near the coast of Honshu. The sign of the transport indicates a preference for upward energy propagation of the eddy flow there. Many of the characteristics, such as the orientation and propagation tendencies of the eddy flow, are similar to eddy flow in the atmosphere and accentuate a similarity between the general circulations of the atmosphere and ocean.

The parameterization of the alpine tundra for CENTURY was updated to reflect current knowledge of the site, and sensitivity analyses were conducted. Verification of results from a 6-yr fertilization experiment in the alpine tested the predictive capabilities of the parameterization. Simulations with increased winter precipitation and with the climate predicted under doubled atmospheric carbon dioxide concentrations were then conducted. Modifications to the parameterization necessary to describe carbon and nitrogen cycling included decreasing the C:N ratios of plant tissues, increasing the amount of nitrogen retranslocated at the end of the growing season, extending the length of the growing season, and lowering the rate of decomposition. The updated parameterization requires 30% greater than observed inputs of net primary productivity to simulate observed levels of total soil carbon suggesting that soil carbon sequestration is not well represented in the model. Carbon and nitrogen cycling showed greatest sensitivity to the length of the growing season and to the temperature regulation of decomposition. Simulation of the nitrogen fertilization experiment resulted in 11% greater productivity than observed empirically, a reasonable verification of the updated parameterization. The major impact from increasing winter precipitation was a 30% increase in the amount of nitrogen in stream flow. Simulation with the climate predicted for a doubling of current carbon dioxide levels reduced production 10% while total soil carbon remained constant. This response was largely controlled by reduced soil moisture during the growing season.

The local population has learned to adapt to the reduced seasonal inundation of the lake basin but are vulnerable to both droughts and excessive inflows. Here, synergistic satellite radar altimetry and near-infrared imagery are employed to gain knowledge of the current flooding patterns. Variations in surface level for the inflowing rivers and the permanent and seasonal lake waters are derived for the 1990s using data from the TOPEX/POSEIDON satellite. National Oceanic and Atmospheric Administration's Advanced Very High Resolution Radiometer images provide additional variations of basin inundation from 1995 to 1998, using a simple pixel histogram technique. With accuracy greater than or equal to 10 cm rms, the altimetry reveals seasonal water-level variations of the order 0.5-6 m and there is a notable rise in minimum levels, 15-35 cm year super(-1) within the lake basin. Peak-level phase lags of 4 to 5 months are also observed between the headwaters of the Chari/Logone rivers and the western lake marshes. Image results reveal that the permanent lake area is similar to 1,385 km super(2), and that with an accuracy of similar to 5% the surrounding regions have been additionally flooding by up to similar to 3,600 km super(2) year super(-1). Despite current basin complexities, the synergistic area/level measurements corroborate the known hydraulic relationship at low water levels. Both measurement sets reflect the poor inundation years of 1993/1994 and 1997/1998, despite the indication of a general recovery in regional precipitation to the southeast of the lake. The observed relationships between precipitation, inundation extent, and surface water level offers these remote sensing techniques as an additional tool for flood/drought forecasting and the availability of future fast delivery data, a mechanism for near-real time monitoring.

Samples of hydroponic nutrient solution and bioreactor effluent with high concentrations (up to 120 mS electrical conductance) of inorganic ions can be analyzed without pretreatment or interference. The presence of non-ionic surfactants did not significantly affect the analysis. Dynamic linear ranges for tested surfactants [Igepon TC-42, ammonium lauryl sulfate, sodium laureth sulfate and sodium alkyl (C10-C16) ether sulfate] were 2 to approximately 500, 1 to approximately 500, 2.5 to approximately 550 and 3.0 to approximately 630 microg/ml, respectively.

An empirical model of sediment resuspension as a function of water depth, wind speed, direction, and fetch was derived from surface gravity wave theory. The model was validated with water-column turbidity imagery obtained from visible and near-IR AVHRR data. Based on model predictions, wind-induced resuspension occurred during all seasons of this study. Model predictions of the critical wind speed required to induce resuspension indicate that winds of 4 m s super(-1) (averaged over all wind directions) resuspend approximately 50% of bottom sediments in the water bodies examined. Winds of this magnitude (4 m s super(-1)) occurred for 80% of the time during the late fall, winter, and early spring and for approximately 30% of the time during the summer. More than 50% of the bottom sediments, on an areal basis, are resuspended throughout the year, indicating the importance of resuspension as a process affecting sediment and biogeochemical fluxes in the Barataria Basin.

AN - 36404716; 7948 AB - PURPOSE: The addition of up to five strap-on solid rocket motors (SRMs) to the Atlas V lift vehicle and the use of larger SRMs on the Delta IV lift vehicle are proposed. Both vehicles would be part of the Evolved Expendable Launch Vehicle (EELV) program. The development, deployment, and operation of evolved expendable launch vehicle (EELV) systems to replace current launch systems used to lift payloads into earth orbit was assesses in the final EIS of April 1998. The EELV systems would replace current Atlas IIA, Delta II and Titan IVB launch systems. EELV systems are designed to meet the requirements of the U.S. National Executable Mission Model (NMM) for both medium-lift (2,500 to 17,000 pounds) and heavy-lift (13,500 to 41,000 pounds) payloads for government space launches at a lower cost than the present expendable launch systems. EELV systems would support military and intelligence launches, as well as civil contractor launches. EELV systems would be the Department of Defense's source of expendable medium- and heavy-lift vehicles for launching payloads into orbit through the year 2020. The launch locations for the EELV program would be Cape Canaveral Air Force Station (CCAFS) in Florida, and Vandenberg Air Force Base (VAFB) in California. Four alternatives, including a No Action Alternative, which would involve the continuation of the existing launch systems as opposed to implementation of the EELV program, were considered in the final EIS. The proposed action would include three concepts. Concept A and Concept B would depict each of the two EELV contractor concepts. Concept A would use Space Launch Complex 41 (SLC-41) at CCAFS and SLC-3W at VAFB for EELV system activities. Under Concept B, the contractors would use SLC-37 at CCAFS and SLC-6 at VAFB. Under Concept A/B, the contractors would use SLC-41 and SLC-37 at CCAFS and SLC-3W and SLC-6 at VAFB. Regardless of the concept chosen, other facilities at both CCAFS and VAFB would be used. The number of launches analyzed for each of these concepts includes the U.S. NMM as well as 16 commercial launches per year. Under Concept A/B, there would be no distinction between government and commercial flights. This final supplement to the final EIS considers a proposal which would allow the addition of up to five strap-on solid rocket motors (SRMs) to the Lockheed Martin Astronautics Atlas V lift vehicle and to allow the use of larger SRMs on the Boeing Delta IV lift vehicle, both of which are part of the EELV program. The launch locations for the Atlas V and Delta IV systems are CCAFS and VAFB. For the analysis in the final supplement, each contractor is assumed to launch approximately 50 percent of EELV flights with SRMs (approximately 30 launches per year overall). The No Action Alternative addressed in this final supplement is the previously approved implementation of the EELV program as analyzed in the final EIS. POSITIVE IMPACTS: Employment associated with launch activities would increase temporarily during program development under the proposed action and the No Action Alternative. Under the proposed action, costs for delivering payloads into space would decrease significantly. NEGATIVE IMPACTS: Under the proposed action and the No Action Alternative, traffic would increase slightly during construction activities, resulting in changes to level-of-service for both installations. Total hazardous materials and hazardous waste would increase; levels under the proposed action would be higher than that generated by the No Action Alternative, which would be greater than those generated under the existing launch system programs or under the EELV program as proposed in the final EIS. Under the No Action Alternative, the construction activities would uncover and disturb soils, increasing the potential for wind and water erosion. Under the proposed action, there would be additional paving for vehicle turnaround at CCAFS. The use of additional SRMs would result in increased deposition of hydrogen chloride into surface waters at both launch installations. Under both alternatives, construction-related activities would generate an increase in local concentrations of particulates, NOx, and other pollutants. The use of SRMs would increase emissions of some criteria pollutants, as well as increased emissions of aluminum oxide, nitrogen oxides, and chlorine compounds into the stratosphere that would adversely affect stratospheric ozone. Sonic booms over the Channel Islands could disturb marine mammals with launches VAFB. Both the proposed action and the No Action Alternative could result in the contribution to the existing orbital debris level.

AN - 72486496; 11543570 AB - This study focuses on the characterization of protein phosphorylation in the gravitropic response in oat shoot pulvini through the use of inhibitors of this process, namely staurosporine, okadaic acid and sodium fluoride. These three inhibitors reduce gravitropic curvature and cause changes in the phosphorylation of 38- and 50-kDa soluble proteins which show different levels of phosphorylation between lower and upper halves of gravistimulated pulvini. A kinetic analysis of phosphorylation shows that the 38- and 50-kDa soluble proteins exhibit different levels of phosphorylation between lower and upper halves of graviresponsive pulvini at 5 min after initiation of gravistimulation of stems. In addition, the phosphorylation of 63- and 70-kDa proteins from a total membrane preparation increases in lower halves of the pulvini following gravistimulation. These phosphoproteins are not found in the plasma membrane fraction. Taken together, at least four kinds of phosphoproteins are gravi-related. Of these, the 38- and 50-kDa soluble phosphoproteins may be involved in the regulation of early stages of the gravitropic response.

AN - 72485802; 11543053 AB - To study the response characteristics of LiF detectors to proton fluence rate and energy, and to observe the thickness effect of the detector. Protons were generated by an accelerator. Proton energy was changed in two ways, i.e. changing the accelerator energy directly, or using detector stacks to absorb the proton energy. The incident proton energy on each chip of detector stacks was calculated according to proton range in LiF. The response of the detector to proton fluence rate was almost constant; when proton energy was above 9 MeV, the response of the detector to proton energy was constant (less than 10% errors). When proton energy was below 9 MeV, the response reduced gradually with the decrease of proton energy. Thickness effect for LiF thicknesses of 0.4mm and 0.8mm was not obvious. The homemade LiF detector is suitable for measurement of space radiation dose. When proton component (below 9 MeV) was abundant in radiation field, the decrease of the relative thermoluminescence efficiency should be taken into consideration.

AN - 72480820; 11543201 AB - During the interplanetary flights the crewmembers will be exposed to cosmic ray radiation with great risk for their health. The absorbed dose due to CR depends on the galactic (GCR) or solar (SCR) origin. GCRs are isotropic and relatively high in energy and deliver a dose nearly constant with time that can be reduced only by means of "heavy" passive protection. The outer walls of the spacecraft usually shield the SCRs up to a few tens of MeV, but during some exceptional solar bursts, a great number of particles, mainly protons, are ejected at higher energies. In this case the dose delivered in a few hours by a solar burst can easily exceed 1 year cumulated dose by GCRS. The high-energy component of SCRs is quasi-directional so that a shielding system based on a superconductive magnetic lens can reduce the daily dose of SCRs to the level delivered by GCRS.

AN - 72480480; 11543049 AB - To study the effects of space conditions on mutation and inheritance of tomato. Air-dried seeds of tomato were carried by a satellite for 7-15 d. These seeds were planted after returning. The mutagenic effects of space conditions on some of their variations of the botanical characteristics were studied. Tomato dry seeds were carried to the outer space by satellite. After returned to the earth it was found that SP1 generation was of their germination percentage lower than the control. This physiological damage returned to normal in SP2 generation. Seeding isoenzyme, plant growth, resistance, and output, showed variation, and profitable variation had been expressed in later generations. The characters were expressed in the progenies. By observation and screen, promising line of tomato TF873, was obtained. It was suggested that space conditions induce profitable mutation of crop and it a possible way for plant mutation breeding.

The AVHRR 10-bit sensor is shown to have the best radiometric resolution, but its poorer spatial resolution limits this sensor's ability to discriminate smaller scale topography. RESURS-01 is a less-well known 8-bit sensor, but this instrument's higher noise and poorer radiometric resolution restrict its utility for ice-sheet research. Landsat TM applies 8-bit quantization over a narrower radiometric range, causing it to saturate for some conditions. This limitation allows TM to achieve a radiometric resolution half that of AVHRR while retaining a much higher spatial resolution. No SPOT imagery was compared, but the sensor is shown to have less radiometric resolution than TM. However, SPOT has better spatial resolution and is less likely to saturate.

Sites in the eastern Kenai Peninsula and Prince William Sound move to the NNW relative to North America, in the direction of Pacific-North America relative plate motion. Velocities decrease in magnitude from nearly the full plate rate in southern Prince William Sound to about 30 mm/yr at Seward and to about 5 mm/yr near Anchorage. In contrast, sites in the western Kenai Peninsula move to the SW, in a nearly trenchward direction, with a velocity of about 20 mm/yr. The data are consistent with the shallow plate interface offshore and beneath the eastern Kenai and Prince William Sound being completely locked or nearly so, with elastic strain accumulation resulting in rapid motion in the direction of relative plate motion of sites in the overriding plate. The velocities of sites in the western Kenai, along strike to the southwest, are opposite in sign with those predicted from elastic strain accumulation. These data are incompatible with a significant locked region in this segment of the plate boundary. Trenchward velocities are found also for some sites in the Anchorage area. We interpret the trenchward velocities as being caused by a continuing postseismic transient from the 1964 great Alaska earthquake. There may be significant along-strike differences in the long-term behavior of the plate interface between the western and eastern Kenai, based on roughly coincident boundaries in the coseismic slip distribution, cumulative postseismic uplift, present-day plate coupling, and stress field. The present postseismic response appears to generate purely trenchward motion, suggesting a creep process that is purely dip slip. Our observations suggest that postseismic processes after the largest earthquakes can influence patterns of deformation for decades after the event. Copyright 2000 by the American Geophysical Union.

Two previously developed atmosphere-removal models were applied to data from Cimmeria Terra (25 degrees S, 213 degrees W). The surface spectra derived for these two models agree well, indicating that the surface and atmosphere emission can be separated and that the exact atmosphere-removal model used has little effect on the derived surface composition. The Cimmeria spectra do not match terrestrial high-silica igneous rocks (granite and rhyolite), ultramafic igneous rocks, limestone, or quartz- and clay-rich sandstone and siltstone. A particulate (sand-sized) sample of terrestrial flood basalt does provide an excellent match in both spectral shape and band depth to the Cimmeria spectrum over the entire TES spectral range. No unusual particle size effects are required to account for the observed spectral shape and depth. The implied grain size is consistent with the thermal inertia and albedo of this region, which indicate a sand-sized surface with little dust. The identification of basalt is consistent with previous indications of pyroxene and basalt-like compositions from visible/near-infrared and thermal-infrared spectral measurements. A linear spectral deconvolution model was applied to both surface-only Cimmeria spectra using a library of 60 minerals to determine the composition and abundance of the component minerals. Plagioclase feldspar (45%; 53%) and clinopyroxene (26%; 19%) were positively identified above an estimated detection threshold of 10-15% for these minerals. The TES observations provide the first identification of feldspars on Mars. The best fit to the Mars data includes only clinopyroxene compositions; no orthopyroxene compositions are required to match the Cimmeria spectra. Olivine (12%; 12%) and sheet silicate (15%; 11%) were identified with lower confidence. Carbonates, quartz, and sulfates were not identified in Cimmeria at detection limits of approximately 5, 5, and 10%, respectively. Their presence elsewhere, however, remains open. The Cimmeria spectra are not well matched by any one SNC meteorite spectrum, indicating that this region is not characterized by a single SNC lithology. The occurrence of unweathered feldspar and pyroxene in Cimmeria, together with the inferred presence of pyroxene and unweathered basalts in other dark regions and at the Viking and Pathfinder landing sites, provides evidence that extensive global chemical weathering of materials currently exposed on the Martian surface has not occurred.

Inversion of computed response functions is carried out using a minimum structure, regularized approach. The upper mantle beneath Carty Lake is approximately an order of magnitude more resistive than the upper mantle beneath Tucson and nearly 1.5 orders of magnitude more resistive than Honolulu and Midway Island. Inversions were also carried out where the minimum structure constraint was removed at known upper mantle discontinuities. These models show a jump in conductivity of approximately 1.5 orders of magnitude across the 660 km discontinuity, a result that is consistent with laboratory experiments on realistic mantle assemblages. Mantle conductivity profiles at Carty Lake are significantly more resistive than those at Tucson, Honolulu, and Midway to depths of approximately 300-400 km. These observations likely reflect differing thermal states, the presence (or absence) of partial melt and volatiles, and may also be related to chemical differences between depleted and undepleted upper mantle. The observed conductivity variations may be interpreted as lateral variations in temperature, partial melt, and/or dissolved hydrogen in olivine. Copyright 2000 by the American Geophysical Union.

During the recent (1993-1995) Bering Glacier surge, a large transfer of ice from the Bagley Ice Field to the Bering Glacier terminus region occurred. We estimated the elastic displacement of the solid Earth due to ice mass redistribution from Global Positioning System (GPS) measurements at sites near the surging glacier. We can account for these displacements by transfer of an ice volume of about 14 km (super 3) from the surge reservoir area to the terminus region. We examined the background seismicity (M (sub L) > or = 2.5) before, during, and after the surge. We found that the occurrence of small earthquakes (M (sub L) < or = 4.0) in the surge reservoir region increased during the surge time interval possibly in response to a decrease in ice mass. This suggests that a small decrease in the vertical stress, sigma (sub 3) , could be enough to modulate the occurrence of small, shallow earthquakes in this dominantly thrust fault setting. During this century the southern Alaska coastal glaciers have been undergoing an overall decrease in volume. Based on our compilation of changes in the extent and thickness of the coastal glaciers between the Malaspina and Bering, we calculated surface displacements due to the Earth's viscoelastic response to annual thinning and to the cumulative retreat over the last 100 years. The uplift of the region due to an average annual thinning rate of 1-6 m/yr in the ablation region is 1-12 mm/yr. For our reference model with a viscosity of 5 / 10 (super 19) Pa s for depths between nearly equal 40 and 200 km the total viscoelastic response due to the retreat over the last century may be as much as a couple of meters within the coastal ablation zone near Icy Bay. The maximum decrease in sigma v between 0 and 10 km was nearly equal 1.0 MPa, which is significant in relation to the stress drops in recent earthquakes ( nearly equal 2 to 10 MPa) but small in relation to the estimated tectonic stress magnitude. Therefore the occurrence of an earthquake such as the St. Elias (1979, M (sub S) = 7.2) may have been advanced in time; however, most of the ongoing stress accumulation would be primarily due to tectonic forces.

The assimilation method used is a degraded version of the Singular Evolutive Extended Kaiman filter approach [Pham et al., 1998] in which the reduced order basis is fixed. The along-track TOPEX/Poseidon sea surface height residuals are introduced in the model every 3 days. Initialization of the model runs appears to be crucial. This is particularly true for the 1992-1996 period, which is characterized by several El Nino and La Nina events and exhibits quite anomalous climatological behavior. An in situ database dedicated to this period was built and used to initialize the model properly. The simulation results with and without assimilation were compared with expendable bathythermograph and Tropical Atmosphere-Ocean in situ observations. The impact of sea surface height assimilation is observed both on the surface and subsurface temperature and velocity fields. The deficiencies of the free model in terms of means and variability structures are significantly reduced. More importantly, the evolution of the model fields over time is considerably improved by the assimilation. These supposedly more realistic assimilated four-dimensional fields are used to investigate the mechanism responsible for the 1992-1996 warm pool replenishment and depletion. This approach provides insights into the combined role of zonal and meridional transports in balancing volume changes in the warm pool. Copyright 2000 by the American Geophysical Union.

The AVHRR data are adjusted for sensor degradation, volcanic aerosol effects, cloud contamination, short-term atmospheric effects (e.g., water vapor and aerosol effects [imgchar=http://ams.allenpress.com/charent/iso_characters_mixed/lo w ercase/les.gif]2 months), solar zenith angle variations, and missing data. Interannual variation in the data is more realistic as a result. The following biophysical parameters are estimated: fraction of photosynthetically active radiation absorbed by vegetation, vegetation cover fraction, leaf area index, and fraction of green leaves. Biophysical retrieval algorithms are tested and updated with data from intensive remote sensing experiments. The multiyear vegetation datasets are consistent spatially and temporally and are useful for studying spatial, seasonal, and interannual variability in the biosphere related to the hydrological cycle, the energy balance, and biogeochemical cycles. The biophysical data are distributed via the Internet by the Goddard Distributed Active Archive Center as a precursor to the International Satellite Land Surface Climatology Project (ISLSCP) Initiative II. Release of more extensive, higher-resolution datasets (0.25 degree by 0.25 degree ) over longer time periods (1982-97/98) is planned for ISLSCP Initiative II.

To reduce this risk, the addition of ten minutes of moderate exercise (75% VO2pk) during prebreathe has been shown to decrease the total prebreathe time from 4 to 2 hours and to decrease the incidence of DCS. The overall purpose of this pilot study was to develop an exercise protocol using flight hardware and an in-flight physical fitness cycle test to perform prebreathe exercise before an EVA. Eleven subjects volunteered to participate in this study. The first objective of this study was to compare the steady-state heart rate (HR) and oxygen consumption (VO2) from a submaximal arm and leg exercise (ALE) session with those predicted from a maximal ALE test. The second objective was to compare the steady-state HR and V02 from a submaximal elastic tube and leg exercise (TLE) session with those predicted from the maximal ALE test. The third objective involved a comparison of the maximal ALE test with a maximal leg-only (LE) test to conform to the in- flight fitness assessment test. The 75% VO2pk target HR from the LE test was significantly less than the target HR from the ALE test. Prescribing exercise using data from the maximal ALE test resulted in the measured submaximal values being higher than predicted VO2 and HR. The results of this pilot study suggest that elastic tubing is valid during EVA prebreathe as a method of arm exercise with the flight leg ergometer and it is recommended that prebreathe countermeasure exercise protocol incorporate this method.

However, they are prone to interpolation errors where climate stations are sparsely distributed. Snow cover is clearly discernible using satellite-obtained optical data because of the high albedo of snow, yet the surface is often obscured by cloud cover. Satellite-obtained passive microwave data, compared with optical data, is relatively unaffected by clouds; however, the snow-cover signature is significantly affected by melting snow and the microwaves may be transparent to thin snow (<3 cm). Both optical and microwave sensors have problems discerning snow beneath forest canopies. This paper describes a method that combines ground and satellite-derived optical and passive microwave data to produce a multiple-dataset snow-cover product. Comparisons with current snow-cover products show that the multiple-dataset product draws together the advantages of each of its component products while minimizing the potential errors. Improved estimates of the snow-covered area are derived through the addition of two snow-cover classes ("thin or patchy" and "high elevation" snow cover) and from the analysis of the climate station data within each class. The compatibility of this method for use with Moderate Resolution Imaging Spectroradiometer data, which will be available in 1999, and with Advanced Microwave Scanning Radiometer data, available in 2000, is also discussed. With the assimilation of these data, the resolution of the multiple-dataset product would be improved both spatially and temporally and the analysis would become completely automated.

AN - 71028388; 10753459 AB - NASA-Johnson Space Center is designing and building a habitat (Bioregenerative Planetary Life Support Systems Test Complex, BIO-Plex) intended for evaluating advanced life support systems developed for long-duration missions to the Moon or Mars where all consumables will be recycled and reused. A food system based on raw products obtained from higher plants (such as soybeans, rice, and wheat) may be a central feature of a biologically based Advanced Life Support System. To convert raw crops to edible ingredients or food items, multipurpose processing equipment such as an extruder is ideal. Volatile compounds evolved during the manufacturing of these food products may accumulate and reach toxic levels. Additionally, off-odors often dissipated in open-air environments without consequence may cause significant discomfort in the BIO-Plex. Rice and defatted soy flours were adjusted to 16% moisture, and triplicate samples were extruded using a tabletop single-screw extruder. The extrudate was collected in specially designed Tedlar bags from which air samples could be extracted. The samples were analyzed by GC-MS with special emphasis on compounds with Spacecraft Maximum Allowable Concentrations (SMACs). Results showed a combination of alcohols, aldehydes, ketones, and carbonyl compounds in the different flours. Each compound and its SMAC value, as well as its impact on the air revitalization system, was discussed.

Titanohematite behaves similarly to hematite and, thus, the grain size dependence of TRM acquisition in hematite is considered as a generalization. The transition between truly MD behavior and tendency towards SD behavior in hematite has been established to be between grain sizes of 0.1 and 0.05 mm. In contrast to magnetite and titanomagnetite, hematite exhibits inverse grain size dependence, with MD hematite acquiring a relatively intense TRM in the geomagnetic field, comparable to sub-micrometer sized magnetite and only an order of magnitude less than SD magnetite. Consequently MD hematite (and by analogy titanohematite) remanence may be of significance as a source of magnetic anomalies at all scales. MD hematite exhibits TRM weak field acquisition behavior that is different from all other magnetic minerals, being the only magnetic mineral having an REM (TRM/SIRM) value >0.1 for TRM acquisition in the geomagnetic field. The very different TRM behavior of MD hematite in contrast to magnetite is due to two factors. The first is the lesser influence of demagnetizing energy with respect to wall pinning energy, at temperatures almost up to the Curie temperature for hematite. The second is the greater importance of the magnetostatic energy in the applied field, which for hematite dominates the total energy at high temperatures.

Calculations for the Gediz basin area give mean annual total evaporation as 395 mm, which is composed of 45% transpiration, 42% soil evaporation and 13% interception. The coefficient of interannual variation of evaporation is found to be 6%, while that for precipitation and net radiation are, respectively, 16 and 2%, illustrating that net radiation has an important effect in modulating interannual variation of evaporation. The mean annual water use efficiency (i.e. the ratio of net carbon accumulation and total evaporation) is ca. 1 gm (super -2) mm (super -1) , and has a coefficient of interannual variation of 5%. A comparison of the mean water use efficiency with field observations suggests that evaporation over the area is utilized well for biomass production. The reference crop evaporation for irrigated areas has annual mean and coefficient of variation as, respectively, 1176 mm and 3%. The total evaporation during three summer months of peak evaporation (June-August) is estimated to be about 575 mm for irrigated crops like maize and cotton. Seasonal variations of the fluxes are presented. JF - Journal of Hydrology AU - Choudhury, B J A2 - Kite, Geoff W.

The expedition was organized as a collaboration between the Dutch and Chinese Academy of Sciences and was supported by the Leonid multi-instrument aircraft campaign (MAC) program (Jenniskens and Butow, 1999). All data presented here were taken at Xinglong Observatory and at a remote station, Lin Ting Kou near Beijing, on the night of 1998 November 16/17. At the Xinglong station, photographic cameras were accompanied by an all-sky television camera equipped with an image intensifier and 15 mm fish-eye objective in order to obtain precise timings for all observed meteors up to magnitude +2. Whereas beginning heights of photographed meteors are all lower than 130 km, those observed by the all-sky television system are at approximately 160 km, and for three brightest events, even >180 km. Such high beginnings for meteors have never before been observed. We also obtained a precise dynamic single-body solution for the Leonid meteor 98003, including the ablation coefficient, which is an important material and structural quantity (0.16 s (super 2) km (super -2) ). From this and from known photometry, we derived a density of this meteoroid of 0.7 g/cm (super 3) . Also, all PE coefficients indicate that these Leonid meteors belonged to the fireball group IIIB, which is typical for the most fragile and weak interplanetary bodies. From a photometric study of the meteor lightcurves, we found two typical shapes of light curves for these Leonid meteors.

We have examined the effects of these heating/cooling cycles experimentally on a bulk composition representing an average Type B CAI composition by varying the nature of the starting material. Although the most recent and/or highest temperature event prior to incorporation into the parent body dominates the texture and chemistry of the CAI, prior events affect the phase compositions and texture. We have determined that a prior low-temperature event (simulated by heating the sample to 1275 degrees C and cooling slowly) increases the likelihood of anorthite crystallization in subsequent higher temperature events. A prior high-temperature event that produced dendritic melilite (simulated by heating the sample to 1550 degrees C and cooling rapidly) results in melilite that shows evidence of rapid crystallization in subsequent lower temperature events. The addition of Pt powder to the starting material appears to enhance the ability of anorthite to nucleate from this composition and increases the number of melilite crystals present in samples that crystallize euhedral melilite.

These structures were compared with similar structures found in Antarctic cryptoendolithic communities. On morphology alone, we conclude that these features are not only terrestrial in origin but probably belong to a member of the Actinomycetales, which we consider was introduced during the Antarctic residency of this meteorite. If true, this is the first documented account of terrestrial microbial activity within a meteorite from the Antarctic blue ice fields. These structures, however, do not bear any resemblance to those postulated to be martian biota, although they are a probable source of the organic contaminants previously reported in this meteorite.

Determined K and Ca concentrations are also reported. Total [Cl] varies considerably, both among meteorites of the same class and among different meteorite classes. The range in [Cl] is approximately 15-177 ppm for ordinary chondrites; approximately 24-650 ppm for enstatite chondrites; approximately 4-177 ppm for eucrites; approximately 7-128 ppm for mesosiderites; approximately 35-268 ppm for acapulcoites and lodranites; and approximately 12-507 ppm for winonaites and iron silicates. As expected, most differentiated meteorites have lower [Cl] compared to chondrites and iron silicates. Analyses of 11 interior samples ( approximately 0.1 g each) of a large L6 chondrite varied over 68-129 ppm, which is a measure of the homogeneity of Cl distribution. By evaluating Ar release during stepwise sample degassing, we separated the Cl into low-temperature and high-temperature components, the former of which may consist of terrestrial contamination. Most samples show low-temperature Cl concentrations of <40 ppm, but for several samples terrestrial Cl contamination constitutes significant fractions of the total Cl. Among most differentiated meteorites, finds show considerably greater low-temperature [Cl] compared to falls.

They consist of the poikilitic and non-poikilitic (interstitial) areas that are heterogeneous on a cm-scale. A detailed electron microprobe analysis of pyroxene and plagioclase glass from these meteorites gives characteristic distributions of major and minor elements. It is striking that pyroxene and plagioclase glass in all three meteorites have nearly identical zoning patterns of these elements, while olivine shows different chemistry. This is because olivine chemistry was largely controlled by a late-stage re-equilibration which did not significantly modify the major and minor element distributions in pyroxene and plagioclase glass. However, a close look at minor element zoning in plagioclase glass exhibits slightly different zoning patterns among these three meteorites, corresponding to different degrees of re-equilibration (degrees of re-equilibration: ALH77005 > LEW88516 > Y-793605). Nevertheless, it is evident that they experienced a very similar igneous crystallization history and they are likely to have originated from the same igneous unit on Mars.

However, its duration was remarkable remaining off the northern Outer Banks for nearly a week generating large waves that impacted the coast. In fact at the US Army Corps of Engineers Research Pier at Duck, wave height was the third highest in the over 20 years of record reaching 6.3 m at a buoy in 20 m of water. Measurements of sea level, including astronomical tides and storm surge, were also near record levels. Preliminary calculations of the elevation of wave runup on the beach (that is, the highest reach of the waves) was among the highest on record. To measure the amount of coastal change, USGS and its partners at NASA and NOAA conducted an airborne laser altimetry survey of the impacted areas, from near the VA-NC line to south of Cape Hatteras at Ocracoke Inlet using NASA's Airborne Topographic Mapper (ATM) These data are being compared to a pre-storm survey of the same area acquired in 1998. Initial analyses show that erosion of dunes between Cape Hatteras and Oregon Inlet was highly variable along the coast. In some areas, dunes retreated greater than 30 m whereas in other areas the dunes were stable. At some of the erosional "hot" spots, overtopping and overwash occurred seriously impacting the coastal highway. A "hot" spot at Rodanthe lead to the loss of several ocean front houses clearly revealed in the laser altimetry data. This spatial variability of "hot" and "cold" spots, which repeated along the coast over scales of kilometers, may be related to varying nearshore geology. Deciphering the causes is a major research objective.

Evidence for this interest includes recent missions to the Moon and Mars to search for water on these two nearby neighbors. Fluid inclusions represent samples of fluid that are trapped in minerals when they form, or at some time after formation. As such, fluid inclusions may provide information on the nature of fluids present during the petrogenesis of a rock or mineral, as well as information concerning the geological history of that rock following its formation. Recent studies of the SNC meteorites Nakhla and Allan Hills 84001 have documented the presence of fluid inclusions with moving bubbles in both of these samples. Owing to the extremely small size of the inclusions (less than a few micrometers) it has not been possible to confirm whether the fluids in the inclusions are water, or carbon dioxide, or some mixture of these two components. However, regardless of the composition, the mere presence of these inclusions in the SNC samples argues for the existence of a separate fluid phase at or near the martian surface at the time that these rocks formed on Mars. In March, 1998, the Monahans H5 chondritic meteorite fell in the west Texas town of Monahans. Upon examination of this meteorite, it was found to contain small amounts of purple halite. Within the halite are rare fluid inclusions containing an aqueous salt solution. The inclusions were undoubtedly trapped in the halite while the sample resided on its asteroid parent body, and either represent water that was produced during formation of the asteroid, or water that was delivered to the asteroid later by an impacting cometary body. More recently, similar purple halite containing aqueous fluid inclusions has been identified in the Zag meteorite which fell in 1998 in Morocco.

Unlike the other pure forms of carbon (diamond and graphite), fullerenes are extractable in an organic solvent (e.g., toluene or 1,2,4-trichlorobenzene). The recognition of this unique property led to the detection and isolation of the higher fullerenes in the Kratschmer/Huffmann arc evaporated graphite soot and in the carbon material in the meteorite and impact deposits. By further exploiting the unique ability of the fullerene cage structure to encapsulate and retain noble gases, we have determined that both the Allende and Murchison fullerenes and the KTB fullerenes contain trapped noble gases with ratios that can only be described as extraterrestrial in origin.

Empirical orthogonal function (EOF) analysis shows that the variability of the sea surface height (SSH) and vertically integrated transport is organized so that in the leading mode the whole Arctic operates as a single gyre. The mode is associated with the Arctic Oscillation (AO) [Thompson and Wallace, 1998], and it explains over 70% of the variance in the vertically integrated transport and 25% of the SSH variability. The physical interpretation of this mode is derived to arise from its close connection to the Atlantic inflow to the Arctic. The mode shows a major shift toward cyclonic circulation in the end of the 1980s which is associated with a large multiyear pulse of Atlantic water to the Arctic. Thus this event appears as the likely initiation of the Atlantic layer warming observed during the recent years [Carmack et al., 1995]. Overall, the first mode shows strong decadal variability as reported by Proshutinsky and Johnson [1997]. The second mode of the oceanic circulation, which explains 9% of the variance in the transport, contains two gyres with opposing cyclonicity in the Eurasia and Canada basins. It projects onto the North Atlantic Oscillation (NAO) pattern and displays a 14 year cycle which is known to exist in the midlatitude North Atlantic surface temperatures [Deser and Blackmon, 1993]. A further examination reveals that this mode describes the variability of the flow through the Barents Sea, which is modulated by the water mass modification due to the local heat flux variability.

This paper presents an analysis of the iron budget in the upper ocean. The global distribution of annual iron assimilation by phytoplankton was estimated from distributions of satellite-derived oceanic primary production and measured (Fe:C) (sub cellular) ratios. The distributions of iron supply by upwelling/mixing and aeolian deposition were obtained by applying (Fe:NO (sub 3) ) (sub dissolved) ratios to the nitrate supply and by assuming the soluble fraction of mineral aerosols. A lower bound on the rate of iron recycling in the photic zone was estimated as the difference between iron assimilation and supply. Global iron assimilation by phytoplankton for the open ocean was estimated to be 12 X 10 (super 9) mol Fe yr (super -1) . Atmospheric deposition of total Fe is estimated to be 96X10 (super 9) mol Fe yr (super -1) in the open ocean, with the soluble Fe fraction ranging between 1 and 10% (or 1-10 X10 (super 9) mol Fe yr (super -1) ). By comparison, the upwelling/entrainment supply of dissolved Fe to the upper ocean is small, approximately 0.7X10 (super 9) mol Fe yr (super -1) . Uncertainties in the aeolian flux and assimilation may be as large as a factor of 5-10 but remain difficult to quantify, as information is limited about the form and transformation of iron from the soil to phytoplankton incorporation. An iron stress index, relating the (Fe:N) demand to the (Fe :N) supply, confirms the production in the high-nitrate low-chlorophyll regions is indeed limited by iron availability.

The dust concentration over Greenland is calculated from sources in central and eastern Asia, which are integrated on-line in the model. The results show that an increase in the latitudinal temperature gradient increases both the Asian dust source strength and the concentration over Greenland. The source increase is the result of increased surface winds, and to a minor extent, the increase in Greenland dust is also associated with increased northward transport. Cooling the climate in addition to this increased gradient leads to a decrease in precipitation scavenging, which helps produce a further (slight) increase in Greenland dust in this experiment. Reducing the latitudinal gradient reduces the surface wind and hence the dust source, with a subsequent reduction in Greenland dust concentrations. Warming the climate in addition to this reduced gradient leads to a further reduction in Greenland dust due to enhanced precipitation scavenging. These results can be used to evaluate the relationship of Greenland ice core temperature changes to changes in the latitudinal and global temperatures.

The SSM/I observations consist of tropical rain rates retrieved using the Goddard Profiling Algorithm and tropical TPW estimates produced by Wentz. In a series of assimilation experiments for December 1992, results show that the SSM/I-derived rain rate, despite current uncertainty in its intensity, is better than the model-generated precipitation. Assimilating rainfall data improves cloud distributions and the cloudy-sky radiation, while assimilating TPW data reduces a moisture bias in the lower troposphere to improve the clear-sky radiation. Together, the two data types reduce the monthly mean spatial bias by 46% and the error standard deviation by 26% in the outgoing longwave radiation (OLR) averaged over the Tropics, as compared with the NOAA OLR observation product. The improved cloud distribution, in turn, improves the solar radiation at the surface. There is also evidence that the latent heating change associated with the improved precipitation improves the large-scale circulation in the Tropics. This is inferred from a comparison of the clear-sky brightness temperatures for TIROS Operational Vertical Sounder channel 12 computed from the GEOS analyses with the observed values, suggesting that rainfall assimilation reduces a prevailing moist bias in the upper-tropospheric humidity in the GEOS system through enhanced subsidence between the major convective centers. This work shows that assimilation of satellite-derived precipitation and TPW can reduce state-dependent systematic errors in the OLR, clouds, surface radiation, and the large-scale circulation in the assimilated dataset. The improved analysis also leads to better short-range forecasts, but the impact is modest compared with improvements in the time-averaged signals in the analysis. The study shows that, in the presence of biases and other errors of the forecast model, it is possible to improve the time-averaged "climate content" in the data without comparable improvements in forecast. The full impact of these data types on the analysis cannot be measured solely in terms of forecast skills.

Glenn Research Center at Lewis Field in support of a National Transportation Safety Board accident investigation are described. An icing research tunnel (IRT) test was conducted in January 1998. Most conditions for the test were based on raw and derived data from the flight data recorder recovered from the accident and on the current understanding of the meteorological conditions near the accident. Using a two-dimensional Navier-Stokes code, the flowfield and resultant lift and drag were calculated for the wing section with various ice shapes accreted in the IRT test. Before the final calculations could be performed extensive examinations of geometry smoothing and turbulence modeling were conducted. The most significant finding of this effort is that several of the 5-min ice accretions generated in the IRT were found by the Navier-Stokes analysis to produce severe lift and drag degradation. The information generated suggests a possible scenario for the kind of control upset recorded in the accident. Secondary findings were that the ice shapes accreted in the IRT were mostly limited to the protected pneumatic boot region of the wing and that during testing activation of the pneumatic boots cleared most of the ice.

Specifically, chicken skeletal muscle cells and rat skeletal muscle cells that had been grown for 7 d in culture were subjected to electrical stimulation for an additional 2 d at a pulse frequency of 0.5 pulses/sec and a pulse duration of 200 msec. In chicken skeletal muscle cells, the beta AR population was not significantly affected by electrical stimulation; however, the ability of these cells to synthesize cyclic AMP was reduced by approximately one-half. In contrast, the beta AR population in rat muscle cells was increased slightly but not significantly by electrical stimulation, and the ability of these cells to synthesize cyclic AMP was increased by almost twofold. The basal levels of intracellular cyclic AMP in neither rat muscle cells nor chicken muscle cells were affected by electrical stimulation.

However, the high data rates and power required to achieve this fine resolution limit the available swath widths and hence the temporal and spatial sampling of the ocean surface, in turn limiting SAR ocean observations to periodic "snapshots" rather than synoptic, frequent views. The wide swath capability of Radarsat and Envisat enhance ocean sampling, reducing it to a few days. The dynamics of many important ocean and atmospheric processes have shorter timescales, however, and may require an entirely new satellite concept to be adequately captured. We examined two different satellite SAR mission concepts with the goal of achieving daily ocean observations. The first concept was for a mission with increased swath width using a single antenna flown at a higher than normal altitude. The second considered using a spacecraft carrying two antennas in a more conventional orbit. Trade-offs between the two missions are discussed.

Many nations have vast economic enterprise zones that cannot be monitored for fishing activities with the available patrol resources. This is particularly true for small Pacific Island nations, whose resources preclude any effective monitoring methods. With wide swath SAR, large ocean areas can be monitored on frequent revisit schedules, thus allowing detected ships to be observed and identified by patrols that are vectored on these targets from cuing derived from the SAR information.

With better temporal coverage, SAR also supplies crucial information for the tracking and monitoring of these features using, for instance, the technique of two-dimensional wavelet analysis. Examples presented in this article of fronts in the Gulf of Mexico and off the mid-Atlantic coast, an oil spill off Point Barrow, Alaska, and internal waves in the South China Sea illustrate some of the myriad ocean applications that are better observed and monitored with wide swath SAR.

AN - 70900932; 10677480 AB - It has long been known that cholera outbreaks can be initiated when Vibrio cholerae, the bacterium that causes cholera, is present in drinking water in sufficient numbers to constitute an infective dose, if ingested by humans. Outbreaks associated with drinking or bathing in unpurified river or brackish water may directly or indirectly depend on such conditions as water temperature, nutrient concentration, and plankton production that may be favorable for growth and reproduction of the bacterium. Although these environmental parameters have routinely been measured by using water samples collected aboard research ships, the available data sets are sparse and infrequent. Furthermore, shipboard data acquisition is both expensive and time-consuming. Interpolation to regional scales can also be problematic. Although the bacterium, V. cholerae, cannot be sensed directly, remotely sensed data can be used to infer its presence. In the study reported here, satellite data were used to monitor the timing and spread of cholera. Public domain remote sensing data for the Bay of Bengal were compared directly with cholera case data collected in Bangladesh from 1992-1995. The remote sensing data included sea surface temperature and sea surface height. It was discovered that sea surface temperature shows an annual cycle similar to the cholera case data. Sea surface height may be an indicator of incursion of plankton-laden water inland, e.g., tidal rivers, because it was also found to be correlated with cholera outbreaks. The extensive studies accomplished during the past 25 years, confirming the hypothesis that V. cholerae is autochthonous to the aquatic environment and is a commensal of zooplankton, i.e., copepods, when combined with the findings of the satellite data analyses, provide strong evidence that cholera epidemics are climate-linked.

AN - 16355003; 7897 AB - PURPOSE: The implementation of programmatic and site-specific changes to the National Aeronautics and Space Administration's (NASA's) Sounding Rocket Program (SRP) is proposed. The NASA SRP supports space and earth sciences research by providing approximately 30 to 40 flight opportunities per year to space scientists in the disciplines of upper atmosphere, plasma physics, solar physics, planetary atmospheres, galactic astronomy, and high energy astrophysics. The environmental studies dealing with ozone depletion and global warming are examples of the scientific programs carried out by NASA for the protection of the planet. Launch vehicles used by the NASA SRP for deployment of scientific payloads have high reliability, short mission lead time, low cost, mobility, and payload recovery and reuse. This final supplement to the final EIS of July 1973 addresses the deletion of launch vehicles that are no longer used, the addition of new launch vehicles and systems in current use, and changes in launch sites and ground support activities. Programmatic changes involve aircraft and other alternatives to sounding rockets, use of alternative fuels for sounding rockets, and a No Action Alternative, which would include the termination of the SRP. The site-specific aspects of this supplemental EIS apply to the environmental impact issues at domestic launch sites at the Wallops Flight Facility (WFF) on the Eastern Shore of Virginia, the Poker Flat Research Range (PFRR) in Alaska, and the White Sands Missile Range (WSMR) in New Mexico. Rocket operations generate hazardous wastes, the disposal of which are managed by NASA at WFF, by the University of Alaska at PFRR and by the Navy at WSMR in accordance with regulatory requirements. Any impacts to land, wetlands, and floodplains of the WSMR stem from the actual impact of launch vehicles and payloads, and may also result from recovery efforts. Five programmatic alternatives, a proposed action, and a No Action Alternative are considered in this supplemental final EIS. Under the proposed action, current observation from suborbital sounding rockets would continue in its present form. POSITIVE IMPACTS: The continued use of the sounding rockets would provide for in situ measurements at altitudes between the maximum altitude of balloons (about 30 miles) and the minimum altitude for satellites (about 100 miles). The NASA SRP activity would continue to contribute significantly to the budgets at the WFF, the WSMR, and the PFRR; the WFF would continue to make a substantial contribution to the local economy. NEGATIVE IMPACTS: The NASA SRP would adversely affect the upper and lower atmosphere, as well as impacts due to noise and landing and recovery operations. The rocket operations would result in emissions of oxides and other pollutants. The metallic and other solid heavier-than-air objects propelled into the atmosphere would land with more or less ballistic trajectories. Endangered and threatened species would be present at all three principal launching sites.

AN - 72477704; 11542871 AB - Now being built at NASA-Ames is a small robot that will work independently alongside astronauts in space. About the size of a softball, the 5-in.-diam. Personal Satellite Assistant (PSA) will serve as an intelligent robot, providing another set of eyes and ears and an extra nose to the crew and ground support personnel. The device will move and operate on its own in the microgravity environment of space-based vehicles. Yuri Gawdiak, principal investigator for the projects, expects astronauts to fly a demonstration model of the device aboard a Space Shuttle in about two years. The first crew to use PSAs will test the examine safety issues. Those tests, if successful, will lead to a demonstration aboard the International Space Station. Gawdiak says the project has an annual budget of about $500,000.

AN - 70548801; 12214612 AB - To investigate the effects of heat and noise environments on lipid peroxidation of erythrocyte membrane in pilots. Twenty-four pilots and twenty-one ground personnel (control group) served as the subjects. The pilots performed flying in heat and noise environments. Glutathione peroxidase (GSHpx) and malondialdehyde [correction of malondiadehyde] (MDA) levels in erythrocyte membrane were determined before flying (6:00 a.m.), immediately after flying (12:00 a.m.) and 8 hours after flying (8:00 p.m.) respectively with a spectrophotometer. Immediately after flying, GSHpx activity in pilot's erythrocyte membrane decreased significantly as compared with that in control group. Immediately after flying and 8 h after flying, MDA contents in pilots increased significantly as compared with that of control group. Heat and noise environments might induce increase of lipid peroxidation reaction and decrease of antioxidant ability.

AN - 70548133; 12214609 AB - To theoretically analyze the thickness effect of a LiF detector for proton measurement. Thickness effect of the detector was calculated by using the definition of the detector dose under ideal and reasonable hypothesis. The thickness effect of the detector was not obvious when protons could penetrate the detector: when proton energy was above 12 MeV, the thickness effect was obvious only on condition that the detector thickness approaches proton range, when proton energy was less than 12 MeV, the thickness effect was not obvious. The thickness effect of the detector was obvious, when protons could not penetrate the detector. Thin detectors should be used in low energy proton measurements to avoid thickness effect of the detector.

The oldest volcanic rocks (Eocene) and possibly the oldest rift basins (Oligocene) of the East African rift system occur in this zone of overlap. The objectives of field, remote sensing, and geochronology (K-Ar and (super 40) Ar/ (super 39) Ar) studies in southwestern Ethiopia were to establish a chronology of rifting and volcanism in the zone of overlap, and to correlate stratigraphic sequences with those in the Kenya rift to the south and in the Main Ethiopian rift to the north. Field observations and cross sections show that basins are bounded by steeply dipping faults, stratal dips are <30 degrees , and that extension accommodated by the intrusion of dikes is volumetrically insignificant. Thus, the style of faulting is similar to that elsewhere in East Africa south of the Afar rift. Initial volcanism between ca. 45 and 33 Ma preceded faulting and uplift, except for reactivation of some Mesozoic rift structures near the Sudan-Ethiopia border and in northern Kenya. Extensional basins began to form in late Oligocene time in the Eastern rift, and in early Miocene time in the Main Ethiopian rift. Small degrees of extension and associated volcanism in the broadly rifted zone may have been triggered by extension in the Red Sea, as well as by lithospheric heating above a mantle plume. The anomalous breadth of the zone is a consequence of rift propagation and migration, rather than basin-and-range-style extension; both the Main Ethiopian rift and Eastern rifts have propagated along north-south lines, and the Eastern rift has migrated approximately 200 km eastward since late Oligocene time. The distribution of seismicity and Quaternary volcanism suggest that the Eastern and Main Ethiopian rifts are currently linked across a 200-km-wide zone between the Omo and Segen basins.

We present preliminary data from several marshes in the New York- New Jersey region in order to understand the late Holocene environmental history of this region. Our project includes salt marsh cores from Hackensack, Piermont, Staten Island, and Jamaica Bay. Our preliminary research has focused on a 11.15 m sediment core from Piermont Marsh, New York (40 degrees N, 74 degrees W) in an attempt to document the Holocene environmental history of the region. Lithology, loss-on-ignition (LOI), pollen, plant macrofossils, charcoal, and foraminifera were analyzed. Core lithology consists of peat, silts, and clays that vary in color and texture. The base of the core is AMS C-14 dated to 4190 yr BP. Preliminary low-resolution analysis of the core to date includes sampling at the 1-meter interval throughout the core. LOI of the sediments ranges from 1% to 85%. Average rate of deposition is about .26 cm/yr. Major changes in pollen percentages are visible throughout the core. While basal samples contain 60% Tsuga (hemlock) pollen, subsequent samples are dominated by Pinus (pine). In contrast, uppermost pollen percentages are comprised primarily of Gramineae (grass) and reflect anthropogenic influence.

Specifically, we found brightenings in the Jovian bKOM emission, followed by a sudden cessation of the bKOM emission and an onset of an nKOM "event" that lasted for some 120 hours. This sequence of events was observed to recur every approximately 12 or 25 days from October, 1991 to mid-January, 1992 when Ulysses was inbound toward Jupiter and at Jovian latitudes <2.3 degrees . These observations indicate that the solar wind structures, which influence the dynamics of Jupiter's magnetosphere, in turn control the radio emissions generated inside the magnetosphere.

Cool sea surface temperature anomalies (SSTAs) were present in the eastern IO along and south of the equator. Beginning in July 1997, warm SSTAs appeared in the western IO, and they peaked in February 1998. An ocean general circulation model is employed to investigate the dynamic and thermodynamic processes that caused the SSTAs associated with this and other similar IO events. The eastern cooling resulted from unusually strong upwelling along the equator and Sumatra. The Sumatran upwelling was forced both locally by the stronger alongshore winds and remotely by equatorial and coastal Kelvin waves. By the end of 1997, weakening of the winds and the associated reduction in latent heat loss led to the elimination of the cold SST anomalies in the east. The western warming was initiated by weaker Southwest Monsoon winds and maintained by enhanced precipitation forcing, which resulted in a barrier layer structure. Analysis of the mixed layer temperature equation indicates that a downwelling Rossby wave contribution was crucial for sustaining the warming into February 1998. It is tempting to suppose that the 1997 event was related to the El Nino-Southern Oscillation (ENSO) event that took place in the Pacific at the same time. Indeed, weaker IO events occur quite regularly in the control run that evolve similarly to the 1997 event, and they are often but not always related to ENSO. We speculate that these events represent a natural mode of oscillation in the IO, which is externally forced by ENSO but also excited by ocean-atmosphere interactions internal to the IO.

For initial testing, the method is applied in the Eurasian Basin because of its relatively simple circulation dominated by the wind. Using eight Argos buoys, 11 strain rate arrays 100-600 km in size are constructed. Daily 100 km resolution sea ice motion derived from SSM/I 85 GHz brightness temperatures is sampled 100-1000 km from the center of the buoy arrays. Over this range of possible scales, a minimum RMS difference (RMSD) for deformation is used to identify an optimal inclusion radius of 600 km corresponding to a length scale of 1000 km. This length scale is typical of local storms confirming a strong connection between wind and observed sea ice motion. On the basis of all 11 arrays, an average RMSD of 2.48 + or - 0.05 cm s (super -1) for velocity vector and 8.8 + or - 0.9 X 10 (super -8) s (super -1) using all four deformation components (theta u (sub i ) /theta x (sub j ) ] is found at the optimal inclusion radius corresponding to average correlation coefficients of 0.896 + or - 0.002 and 0.729 + or - 0.030, respectively. RMSD are found to scale with the temporal and spatial uncertainties of the SSM/I suggesting that even better results can be achieved with higher resolution instruments.

In order to improve the likelihood of success in using regional forecasts in Uganda, particularly in the agricultural sector, climate analysis was performed at the sub-regional level with distinctions being made between unimodal (short season peak in August) and bimodal (short season peak in November) rainfall zones. Monthly climate data from 1931 to 1960 were available for 33 sites. Averaging across all stations, it is shown that Pacific Ocean NINO3 region sea-surface temperatures (SSTs) from July to September (JAS) are significantly correlated with both the concurrent August-September (AS) rainfall (r = -0.75) and the following November-December (ND) rainfall (r = 0.57), but with opposite signs. When station data are separated into uni- and bimodal sites, it becomes clear that the importance of ENSO events is different in the two zones. In the unimodal zone, El Nino events are associated with a depression of the August peak in rainfall, but a lengthening of the season, potentially providing an opportunity for growing later-maturing crops. At bimodal sites, there is very little impact in August but November rainfall is enhanced in El Nino years and depressed in La Nina years. Given a forecast of ENSO, the primary strategies that will be useful in farm management will differ by rainfall zone and will revolve around the choice of crop or cultivar and the timing of planting in order to make optimal use of the growing period.

In the first half of the analysis, which focuses on precipitation variance, the contributions of ocean, atmosphere, and land processes to this variance are characterized, to first order, with a simple linear model. The resulting clean separation of the contributions leads to two results: 1) land and ocean processes have essentially different domains of influence, that is, the amplification of precipitation variance by land-atmosphere feedback is most important outside of the regions (mainly in the Tropics) that are most affected by sea surface temperatures; and 2) the strength of land-atmosphere feedback in a given region is controlled largely by the relative availability of energy and water there. In the second half of the analysis, the potential for seasonal-to-interannual predictability of precipitation is quantified under the assumption that all relevant surface boundary conditions (in the ocean and on land) are themselves perfectly predictable. Although the chaotic nature of the atmospheric circulation imposes fundamental limits on precipitation predictability in many regions, foreknowledge of sea surface temperature contributes significantly to predictability in the Tropics, and foreknowledge of land surface moisture state contributes significantly to predictability in transition zones between dry and humid climates. Thus, soil moisture initialization or assimilation in a seasonal-to-interannual forecasting system would be especially beneficial in these transition zones.

A single-disk laboratory unit was operated over a range of disk rotation speeds and permeation rates (as controlled by the global transmembrane pressure drop) that were calculated to favor various conditions of particle transport and deposition. Permeate flux was found to be relatively insensitive to particle concentration in the feed stream. Thus, this membrane configuration appears to be well suited to the treatment of suspensions at high concentrations. However, the interplay between appropriate operating conditions to maintain permeate flux and the size of particles in the feed suspensions must be taken into account. Fouling was found to decrease with rotation rate and increase with transmembrane pressure (and therefore the initial permeate flux). Reductions in fouling observed at higher rotational speeds are attributed primarily to a high centrifugal force and radial component of drag on particles near the membrane surface. However, a trade off exists between the generation of high shear rates and centrifugal accelerations via high rotation rates and the radial distribution of the transmembrane pressure drop across the membrane that may locally reduce or reverse the flow of permeate across the membrane.

Over the past 10 years it has been demonstrated that ocular responses to linear motion are inversely proportional to viewing distance. This fact holds true regardless of whether the motion is due to translational motion of the visual scene, mediated by the ocular following reflex or due to translational head motion, mediated by the translational vestibulo-ocular reflex (TVOR). Both reflexes result in compensatory ocular responses which preserve the stability of the image on the retina. However, these studies were all conducted with the animal's head restrained, a condition that is not representative of normal experience. When the head is free to move, changes in the visual axis are associated with movements of both the eyes and the head (i.e., gaze). Studies using humans and non-human primates have demonstrated marked differences in the eye movements evoked during rotational motion when head-free and head-restrained results were compared. The proposed studies will examine the compensatory eye and head movements in 'head-free' primates exposed to brief vertical translations. The primates will be trained to fixate on a small target light positioned at various distances. Specific questions will address 1) how the effect of viewing distance is parsed between the command signals driving the eyes and the head during a compensatory gaze shift in the dark (translational gaze reflex, TGR), 2) whether anticompensatory inertial movements of the eyes, due to transient accelerations are dampened when the head is free to move, and 3) the latency of the vertical TGR. The Vertical Free-Fall Sled (VFS) produces a transient vertical linear acceleration characterized by an abrupt onset followed by a gradual deceleration. My previous work using the VFS, made use of this property to provide the first accurate measurement of the latency of the vertical TVOR in rhesus monkeys. In the proposed study, rapid onset of the stimulus will allow us to examine the compensatory visual and vestibular responses prior to the onset of visual feedback. Because an abrupt onset to the stimulus is achievable, it will be possible to characterize the temporal and spatial parsing of this signal - a necessary step towards understanding gaze control during normal behaviors such as locomotion where viewing distance is not static.

AN - 85236974; pmid-11506652 AB - The flanker task, introduced by Eriksen and Eriksen [Eriksen, B. A., & Eriksen, C. W. (1974). Effects of noise letters upon the identification of a target letter in a nonsearch task. Perception & Psychophysics, 16, 143--149], provides a means to selectively manipulate the presence or absence of response competition while keeping other task demands constant. We measured brain activity using functional magnetic resonance imaging (fMRI) during performance of the flanker task. In accordance with previous behavioral studies, trials in which the flanking stimuli indicated a different response than the central stimulus were performed significantly more slowly than trials in which all the stimuli indicated the same response. This reaction time effect was accompanied by increases in activity in four regions: the right ventrolateral prefrontal cortex, the supplementary motor area, the left superior parietal lobe, and the left anterior parietal cortex. The increases were not due to changes in stimulus complexity or the need to overcome previously learned associations between stimuli and responses. Correspondences between this study and other experiments manipulating response interference suggest that the frontal foci may be related to response inhibition processes whereas the posterior foci may be related to the activation of representations of the inappropriate responses.

AN - 72488220; 11543553 AB - Biospheric studies of coral reefs require a planetary perspective that only remote sensing from space can provide. This article reviews aspects of monitoring and mapping coral reefs using Landsat and Spot satellite images. It details design considerations for developing a sensor for equatorial orbiting spacecraft, including spectral characteristics of living corals and the spatial resolution required to map coral reef communities. Possible instrumentation choices include computer techniques, filtered imagers, push-broom spectral imagery, and a newly developed hyperspectral imaging scheme using tomographic reconstruction. We compare the salient features of each technique and describe concepts for a payload to conduct planetary-scale coral reef monitoring.

AN - 72487399; 11542865 AB - For a better understanding of oncogenic cell transformation by ionizing radiation, we conducted experiments with ultrasoft X rays and low energy alpha particles. Confluent C3H10T1/2 cells were irradiated by Al-K (1.5 keV) X rays or alpha particles from plutonium through a thin mylar sheet, on which the cells attached and grew. Our results indicated that Al-K X rays were more effective in causing cell inactivation and oncogenic transformation than 60Co gamma rays but less effective than 1.0 and 3.7 MeV alpha particles. There was no significant difference between 1.0 and 3.7 MeV alpha particles in transforming cells although the latter were slightly more effective than the former in producing lethal effect. These results indicated that track structure is important in causing biological effects by ionizing radiation.

AN - 72487357; 11542855 AB - The heavy ion component of the cosmic radiation remains problematic to the assessment of risk in manned space flight. The biological effectiveness of HZE particles has yet to be established, particularly with regard to nervous tissue. Using heavy ions accelerated at the AGS of Brookhaven National Laboratory, we study the neurotoxic effects of iron particles. We exposed retinal explants, taken from chick embryos, to determine the dose response relationships for neurite outgrowth. Morphometric techniques were used to evaluate the in vitro effects of 1 GeV/a iron particles (LET 148 keV/micrometer). Iron particles produced a dose-dependent reduction of neurite outgrowth with a maximal effect achieved with a dose of 100 cGy. Doses as low as 10-50 cGy were able to induce reductions of the neurite outgrowth as compared to the control group. Neurite generation is a more sensitive parameter than neurite elongation, suggesting different mechanism of radiation damage in our model. These results showed that low doses/fluences of iron particles could impair the retinal ganglion cells' capacity to generate neurites indicating the highly neurotoxic capability of this heavy charged particle.

AN - 72487222; 11543556 AB - The food system, being designed for the BIO-Plex (Bioregenerative Planetary Life Support Systems Test Complex), will be a plant-based diet that requires most of the food to be grown, processed, and prepared in the BIO-Plex. Conversion of crops to edible foods will require extensive food processing within the closed environment of this habitat. Because all consumables in the BIO-Plex will be recycled and reused, food safety is a primary concern. Multifunctional equipment necessary for food processing of the baseline crops (wheat, soybeans, rice, peanuts, dried beans, potatoes, sweet potatoes, lettuce, chard, tomatoes, green onions, carrots, and radishes) was identified. Recommendations for placement of the food processing equipment in the Interconnecting Transfer Tunnel (ITT) of the BIO-Plex were made to facilitate the processing flow diagrams, increase work efficiency, and prevent cross-contamination of pathogens and antinutrients. Sanitation equipment and procedures necessary during food processing in the ITT are described.

AN - 72486329; 11542863 AB - Genomic instability is the increased rate of acquisition of alterations in the mammalian genome, and includes such diverse biological endpoints as chromosomal destabilization, aneuploidy, micronucleus formation, sister chromatid exchange, gene mutation and amplification, variations in colony size, reduced plating efficiency, and cellular transformation. Because these multiple endpoints persist long after initial radiation exposure, genomic instability has been proposed to operate as a driving force contributing to genetic plasticity and carcinogenic potential. Many of these radiation-induced endpoints depend qualitatively and quantitatively on genetic background, dose and LET. Differences in the frequency and temporal expression of chromosomal instability depend on all three of the foregoing factors. On the other hand, many of these endpoints appear independent of dose and show bystander effects, implicating non-nuclear targets and epigenetic regulatory mechanisms.

AN - 72486176; 11542859 AB - The SilEye experiment aims to study the cause and processes related to the anomalous Light Flashes (LF) perceived by astronauts in orbit and their relation with Cosmic Rays. These observations will be also useful in the study of the long duration manned space flight environment. Two PC-driven silicon detector telescopes have been built and placed aboard Space Station MIR. SilEye-1 was launched in 1995 and provided particles track and LF information; the data gathered indicate a linear dependence of FLF(Hz) ( 4 2) 10(3) 5.3 1.7 10(4) Fpart(Hz) if South Atlantic Anomaly fluxes are not included. Even though higher statistic is required, this is an indication that heavy ion interactions with the eye are the main LF cause. To improve quality and quantity of measurements, a second apparatus, SilEye-2, was placed on MIR in 1997, and started work from August 1998. This instrument provides energetic information, which allows nuclear identification in selected energy ranges; we present preliminary measurements of the radiation field inside MIR performed with SilEye-2 detector in June 1998.

AN - 72484520; 11543154 AB - The LET dependences of thermoluminescence dosimeters of Mg2SiO4:Tb (TLMS) and radiophotoluminescent glass dosemeters (RPLG) were examined using high energy, heavy ion beams. TLMS kept its efficiency below 10 keV micrometer-1 and decreased almost linearly with the logarithm of LET for higher LET particles. The efficiency of RPLG decreased more gradually than TLMS although its reduction was observed at a lower LET region around 0.5 keV micrometer-1. Accordingly, the ratio of TLMS to RPLG valued showed a maximum peak around 20 keV micrometer-1 of LET. The results obtained with both dosemeters in the 40 day space mission in the Russian space station Mir showed that not only dose level but also radiation quality were varying considerable in the Mir Core Module.

AN - 72482544; 11542861 AB - Understanding the effects of single-particles from conventional radiation biology experiments is problematic due to the stochastics of particle tracks. This complicates the determinations of risk associated with low doses. We have developed a charged particle microbeam, which allows individually counted particles to be delivered to precise cellular locations. The system is capable of delivering a single charged particle with > 99% efficiency. Of these particles 90% are delivered with a resolution of +/- 2 micrometers and 96% with a resolution of +/- 5 micrometers. We have carried out preliminary studies in Chinese hamster V79 cells to monitor the effectiveness of low energy protons at inducing cytological damage. We have used the micronucleus assay as a measure of predominantly lethal chromosome damage. The effects of a single 3.2 MeV proton delivered individually to cells could be measured, with less than 2% of the exposed cells producing micronuclei 24 hours later. The yield of micronuclei formation was essentially linear up to the highest dose (30 particles per cell nucleus) delivered. Ultimately, the ability to target particles to different parts of the cell nucleus may start to impact on models available for chromosome aberration formation and chromosomal Organisation and mechanisms underlying genomic instability.

AN - 72482493; 11542856 AB - Primary mixed cultures of astrocytes and microglia were obtained from neonatal mice, and were irradiated with high-LET carbon ions. Immunohistochemical staining showed astrocytes survived more prominently than microglia. Tagged with specific antibodies, astrocytes and microglia surviving after irradiation were counted by flow cytometry. Decreases in the number of microglia and astrocytes were detected at a dose as small as 2 Gy when Day 5 cultures were irradiated with 13 keV/micrometer carbon ions. When the cultures were irradiated on Day 10, the dose-dependent decrease of microglia was more prominent for 13 keV/micrometer carbon ions than 70 keV/micrometer carbon ions. Astrocytes showed a marginal decrease at Day 10 and Day 14. We concluded that microglia are more sensitive than astrocytes to carbon ions and X-rays, and that the radiosensitivity of microglia depends on both differentiation/proliferation status and radiation quality.

AN - 72481933; 11542854 AB - It has been suggested that a manned mission to Mars be launched at solar maximum rather than at solar minimum to minimize the radiation exposure to galactic cosmic rays. It is true that the number of hits from highly ionizing particles to critical regions in the brain will be less at solar maximum, and it is of interest to estimate how much less. We present here calculations for several sites within the brain from iron ions (z = 26) and from particles with charge, z, greater than or equal to 15. The same shielding configurations and sites in the brain used in an earlier paper for solar minimum are employed so that direct comparison of results between the two solar activity conditions can be made. A simple pressure-vessel wall and an equipment room onboard a spacecraft are chosen as shielding examples. In the equipment room, typical results for the thalamus are that the probability of any particles with 7 greater than or equal to 15 and from 2.3 percent to 1.3 percent for iron ions. The extra shielding provided in the equipment room makes little difference in these numbers. We conclude that this decrease in hit frequency (less than a factor of two) does not provide a compelling reason to avoid solar minimum for a manned mission to Mars. This conclusion could be revised, however, if a very small number of hits is found to cause critical malfunction within the brain.

AN - 72481070; 11542860 AB - Induction of DNA double-strand breaks (dsb) and their distribution are dependent on the energy deposition pattern within the cell nucleus (physical structure) and the ultrastructure of the chromosomes and its variation by the cell cycle and gene activities (biological structure). For electron radiation very similar RBE-values are observed for mammalian and yeast cells (AlK, 1.5 keV, 15 keV/micrometer: 2.6 in mammalian cells and 2.2 in yeast; CK 0.278 keV, 23 keV/micrometer: approx. 2.5 in mammalian cells and 3.8 in yeast). In contrast, the RBE-values for the induction of dsb of 4He2+ and light ions in the LET range from about 100 keV/micrometer up to 1000 keV/micrometer are significantly higher for yeast cells compared to mammalian cells. For example, the RBE-value of alpha-particles (120 keV/micrometer) is about 1.2 for mammalian cells whereas for yeast the RBE-value is about 2.5. The yeast chromatin has less condensed fibres compared with mammalian cells. Since a single CK photoelectron can induce only one dsb, the different condensation of the mammalian and yeast chromatin has no influence. However, particles may induce more than one dsb when traversing a chromatin fibre. The probability for the induction of closely neighboured dsb is higher the more condensed the chromatin fibres are. Since small DNA fragments (50 bp up to several kbp) are lost by standard methods of lysis, the underestimation of dsb yields increases with fibre condensation, which is in accordance with the observes dsb yields in mammalian cells and yeast. In order to obtain relevant yields of dsb (and corresponding RBE-values) the measurement of all DNA fragments down to about 50 bp are needed.

AN - 72479027; 11543222 AB - A low-energy neutron transport algorithm for use in space-radiation protection is developed. The algorithm is based upon a multiple energy group analysis of the straight ahead Boltzmann equation utilizing a mean value theorem for integrals. The algorithm developed is then verified by using a collocation method solution on the same straight ahead Boltzmann equation. This algorithm was then coupled to the existing NASA Langley HZETRN (high charge and energy transport) code through the evaporation source term. Evaluation of the neutron fluence generated by the February 23, 1956 solar particle event for an aluminum-water shield-target configuration is then compared with the LAHET Monte Carlo calculation for the same shield-target configuration. The algorithm developed showed a great improvement in results over the unmodified HZETRN solution. A bidirectional modification of the evaporation source produced further improvement of the fluence.

AN - 72478185; 11543166 AB - The SVET Greenhouse on-board the Orbital Station Mir was used to measure canopy photosynthesis and transpiration rates for the first time in space. During the Greenhouse IIB experiment on Mir (June-January 1997), carbon and water vapor fluxes from two wheat (cv. Superdwarf) canopies were measured using the US developed Gas Exchange Measurement System (GEMS). Gas analyzers capable of resolving CO2 concentration differences of 5 micromoles mol-1 against a background of 0.9% CO2, are necessary to measure photosynthetic and respiratory rates on Mir. The ability of the GEMS gas analyzers to measure these CO2 concentration differences was determined during extensive ground calibrations. Similarly, the sensitivity of the analyzers to water vapor was sufficient to accurately measure canopy evapotranspiration. Evapotranspiration, which accounted for over 90% of the water added to the root zone, was estimated using gas exchange and used to estimate substrate moisture content. This paper presents canopy photosynthesis and transpiration data during the peak vegetative phase of development in microgravity.

AN - 72475375; 11542858 AB - The effects of exposure to heavy particles on behaviors mediated by the central nervous system (CNS) are qualitatively different than the effects produced by exposure to other types of radiation. One behavior mediated by the CNS is the amphetamine-induced taste aversion, which is produced by pairing a novel tasting solution with injection of amphetamine. When the conditioning day is three days following irradiation, exposing rats to low doses of 56Fe particles (600 MeV/n or 1 GeV/n) eliminates the taste aversion produced by injection of amphetamine, which is dependent upon the integrity of the central dopaminergic system, but has no effect on the aversion produced by injection of lithium chloride which is mediated by the gastrointestinal system. In contrast to the effects obtained using heavy particles, exposing rats to 60CO gamma rays or to fission spectrum neutrons has no selective effect upon the acquisition of either amphetamine- or lithium chloride-induced taste aversions. When the conditioning day occurs four months following exposure to 1 GeV/n 56Fe particles, there is an enhancement of the amphetamine-induced taste aversion. The implications of these findings for approaches to risk assessment are considered.

AN - 72475318; 11542850 AB - Amphibians possess the ability to vomit in response to a variety of stimuli that provoke emesis in mammals. Pharmacological studies have establish that the ejection of gastric contents and the basic mechanism for vomiting have been phylogenetically conserved among these tetrapods. As part of on-going comparative studies on emesis in vertebrates, we previously documented that some postmetamorphic anurans and salamander larvae experience motion-induced emesis when exposed to the provocative stimulus of parabolic aircraft flight. However, more recent experiments suggest that there are strict conditions for inducing emesis in amphibians exposed to parabolic flight and that amphibians are not as sensitive to this stimulus as mammals. Further studies on emesis in lower vertebrates may help us understand the processes that cause emesis in abnormal gravitational regimes.

AN - 72475033; 11542857 AB - Our research over the last several years has suggested that young (3 mo) rats exposed to whole-body 56Fe irradiation show neuronal signal transduction alterations and accompanying motor behavioral changes that are similar to those seen in aged (22-24 mo) rats. Since it has been postulated that 1-2% of the composition of cosmic rays contain 56Fe particles of heavy particle irradiation, there may be significant CNS effects on astronauts on long-term space flights which could produce behavioral changes that could be expressed during the mission or at some time after the return. These, when combined with other effects such as weightlessness and exposure to proton irradiations may even supercede mutagenic effects. It is suggested that by determining mechanistic relationships that might exist between aging and irradiation it may be possible to determine the common factor(s) involved in both perturbations and develop procedures to offset their deleterious effects. For example, one method that has been effective is nutritional modification.

AN - 70854189; 10630971 AB - A set of four tissue-equivalent proportional counters (TEPCs), with their detector heads at the centers of 0 (bare), 3, 7 and 9-inch-diameter aluminum spheres, were flown on Shuttle flight STS-89. Five such detectors at the centers of polyethylene spheres were flown 1 year earlier on STS-81. The results of dose-depth dependence for the two materials convincingly show the merits of using material rich in hydrogen to decrease the radiation exposure to the crew. A comparison of the calculated galactic cosmic radiation (GCR) absorbed dose and dose-equivalent rates using the radiation transport code HZETRN with nuclear fragmentation model NUCFRG2 and the measured GCR absorbed dose rates and dose-equivalent rates shows that they agree within root mean square (rms) error of 12.5 and 8.2%, respectively. However, there are significant depth-dependent differences in the linear energy transfer (LET) spectra. A comparison for trapped protons using the proton transport code BRYNTRN and the AP-8 MIN trapped-proton model shows a systematic bias, with the model underpredicting dose and dose-equivalent rates. These results show the need for improvements in the radiation transport and/or fragmentation models.

AN - 70543898; 12038486 AB - Biological dosimetry has provided experimental proof of the high sensitivity of the biologically effective UVB doses to changes in atmospheric ozone and has thereby confirmed the predictions from model calculations. The biological UV dosimeter 'biofilm' whose sensitivity is based on dried spores of B. subtilis as UV target weights the incident UV radiation according to its DNA damaging potential. Biofilm dosimetry was applicated in space experiments as well as in use in remote areas on Earth. Examples are long-term UV measurements in Antarctica, measurements of diurnal UV profiles parallel in time at different locations in Europe, continuous UV measurements in the frame of the German UV measurement network and personal UV dosimetry. In space biofilms were used to determine the biological efficiency of the extraterrestrial solar UV, to simulate the effects of decreasing ozone concentrations and to determine the interaction of UVB and vitamin D production of cosmonauts in the MIR station. c2001 COSPAR Published by Elsevier Science Ltd.

These sensors employ mid-infrared difference-frequency generation (DFG) in periodically poled lithium niobate (PPLN) crystals pumped by two single-frequency solid state lasers such as diode lasers, diode-pumped solid state, and fiber lasers. Ultrasensitive, highly selective, and real-time measurements of several important atmospheric trace gases, including carbon monoxide, nitrous oxide, carbon dioxide, formaldehyde [correction of formaldehye], and methane, have been demonstrated.

AN - 70536832; 12038487 AB - Biological UV (ultraviolet) dosimetry was applied using the biofilm-technique (DLR patent) to determine the UV levels weighted of biologically weighted UV radiation at the INTA Sounding Station of El Arenosillo at Huelva, Spain (37 degrees 06'N, 6 degrees 44'W, 50 m a s 1=above sea level) on 2 days in 1997 [correction of 1977] (April 1, and May 5). Exposure periods were calculated for clear sky days using a radiative transfer model for erythemal doses to reach 1.3 to 1.5 MED (minimal erythemal dose). Reliability of the radiative transfer model was demonstrated by the doses registered by a Yankee-UV biometer for the same exposure periods as used for the biosensor. This work presents the methodology employed (biofilm-technique utilized [correction of utiliced], calculation of exposing periods with radiative transfer model, etc) and the results obtained with the Yankee biometer and the biofilm. At noon, the ratio of biofilm measurements (Ieff, W/m2=biological effective irradiance, in W/m2) to the UV Biometer data (in MED/h) was 3-4. c2001 COSPAR Published by Elsevier Science Ltd.

AN - 70534647; 12038484 AB - To determine the impact of environmental UV radiation on human health and ecosystems demands monitoring systems that weight the spectral irradiance according to the biological responses under consideration. In general, there are three different approaches to quantify a biologically effective solar irradiance. (i) weighted spectroradiometry where the biologically weighted radiometric quantities are derived from spectral data by multiplication with an action spectrum of a relevant photobiological reaction, e.g. erythema, DNA damage, skin cancer, reduced productivity of terrestrial plants and aquatic foodweb, (ii) wavelength integrating chemical-based or physical dosimetric systems with spectral sensitivities similar to a biological response curve, and (iii) biological dosimeters that directly weight the incident UV components of sunlight in relation to the effectiveness of the different wavelengths and to interactions between them. Most biological dosimeters, such as bacteria, bacteriophages, or biomolecules, are based on the UV sensitivity of DNA. If precisely characterized, biological dosimeters are applicable as field and personal dosimeters. c2001 COSPAR Published by Elsevier Science Ltd. All rights reserved.

AN - 70531941; 12038488 AB - As a consequence of the stratospheric ozone layer depletion biological systems can be damaged due to increased UV-B radiation. The aim of biological dosimetry is to establish a quantitative basis for the risk assessment of the biosphere. DNA is the most important target molecule of biological systems having special sensitivity against short wavelength components of the environmental radiation. Biological dosimeters are usually simple organisms, or components of them, modeling the cellular DNA. Phage T7 and polycrystalline uracil biological dosimeters have been developed and used in our laboratory for monitoring the environmental radiation in different radiation conditions (from the polar to equatorial regions). Comparisons with Robertson-Berger (RB) meter data, as well as with model calculation data weighted by the corresponding spectral sensitivities of the dosimeters are presented. Suggestion is given how to determine the trend of the increase in the biological risk due to ozone depletion. c2001 COSPAR Published by Elsevier Science Ltd. All rights reserved.

AN - 70493760; 11762389 AB - Long-term, whole crop CO2 exchange measurements can be used to study factors affecting crop growth. These factors include daily carbon gain, cumulative carbon gain, and carbon use efficiency, which cannot be determined from short-term measurements. We describe a system that measures semicontinuously crop CO2 exchange in 10 chambers over a period of weeks or months. Exchange of CO2 in every chamber can be measured at 5 min intervals. The system was designed to be placed inside a growth chamber, with additional environmental control provided by the individual gas exchange chambers. The system was calibrated by generating CO2 from NaHCO3 inside the chambers, which indicated that accuracy of the measurements was good (102% and 98% recovery for two separate photosynthesis systems). Since the systems measure net photosynthesis (P-net, positive) and dark respiration(R-dark, negative), the data can be used to estimate gross photosynthesis, daily carbon gain, cumulative carbon gain, and carbon use efficiency. Continuous whole-crop measurements are a valuable tool that complements leaf photosynthesis measurements. Multiple chambers allow for replication and comparison among several environmental or cultural treatments that may affect crop growth. Example data from a 2 week study with petunia (Petunia x hybrida Hort. Vilm.-Andr.) are presented to illustrate some of the capabilities of this system.

Potassium-argon ages of 12 samples range from near zero to 670+ or -91 Ma. These ages confirm the martian origin of the iddingsite, but it is not clear whether any or all of the ages represent iddingsite formation as opposed to later alteration or incorporation of martian atmospheric (super 40) Ar. In any case, because iddingsite formation requires liquid water, this data requires the presence of liquid water near the surface of Mars at least as recently as 1300 Ma ago, and probably as recently as 650 Ma ago. Krypton and Xe analysis of a single 34 mu g sample indicates the presence of fractionated martian atmosphere within the iddingsite. This also confirms the martian origin of the iddingsite. The mechanism of incorporation could either be through interaction with liquid water during iddingsite formation or a result of shock implantation of adsorbed atmospheric gas.

Shock events may have overprinted all primordial magnetic records in meteorites. Shock metamorphism stages ranging from very little to extreme, when melting takes place, have been identified in meteorites. We are examining the creation and destruction of magnetic remanence associated with shock. In this paper, we develop a preliminary framework for understanding the magnetic properties of fine-grained Fe particles (20-110 nm), which carry most of the remanent magnetization in lunar samples and, by extension, the kamacite phase in meteorite samples. Initial experiments on shock effects due to a first-order shock-induced crystallographic transformation are described. The first characterization of pre- and postshock magnetic properties for sized Fe particles and the first characterization of the transformation remanent magnetization (TMRM) associated with the face-centered-cubic (fcc) to body-centered-cubic (bcc) transformation in fine particle Fe spheres are described. This is equivalent to the 13 GPa transitions in bcc Fe. We show that the TMRM is in the same direction as the ambient magnetic field present during the shock, but is deflected from the field direction by 30-45 degrees and that the remanence intensity is 1-2 orders of magnitude less than expected for thermoremanent magnetization (TRM) acquired during cooling through the Curie temperature. Isothermal remanence acquisition curves (RA) reveal the increasing magnetic hardness due to shock. Magnetic hysteresis loops are used to characterize the particle size and the shock-induced magnetic anisotropy. Thermal demagnetization experiments describe the probable presence of particle size effects and the effects associated with recovery-recrystallization due to the annealing that takes place during the thermomagnetic experiment. These observations have implications for paleofield determinations and the recognition of thermal unblocking. A TMRM mechanism could produce a shock overprint in a meteorite and might impart a significant directional feature in an asteroid magnetic signature.

The obtained Raman spectra of the amphiboles are similar to those of kaersutite, reconfirming the previous studies that they are kaersutitic amphiboles enriched in Ca, Al, and Ti. Even though actinolite belongs to the same amphibole group (calcic amphibole) as kaersutite, the Raman spectra of terrestrial actinolite are distinct from those of kaersutite, probably reflecting complex amphibole crystal structures. The Al-Ti-rich pyroxene observed in the magmatic inclusions within LEW 88516 olivine is compositionally similar to kaersutite but shows Raman spectra nearly identical to the regular pyroxene rather than amphibole. In contrast to amphibole, this will be due to relatively simple crystal structures of pyroxene. Thus, the Raman spectra of Al-Ti-rich phases in the martian meteorites are distinct between kaersutite and Al-Ti-rich pyroxene, and this study demonstrates that micro Raman spectroscopy is one of the best tools to perform mineralogical characterization of mineral phases in martian meteorites.

Powerful analytical techniques are available that require, under favorable circumstances, single particles of only a few nanograms for entire suites of fairly comprehensive characterizations. A returned sample of >1000 particles with total mass of just 1 mu g permits comprehensive quantitative geochemical measurements that are impractical to carry out in situ by flight instruments. The main goal of this paper is to describe the state-of-the-art in microanalysis of astromaterials. Given that we can analyze fantastically small quantities of asteroids and comets, etc., we have to ask ourselves, how representative are microscopic samples of bodies that measure a few to many kilometers across? With the Galileo flybys of Gaspra and Ida, it is now recognized that even very small airless bodies have indeed developed a particulate regolith. Acquiring a sample of the bulk regolith, a simple sampling strategy, provides two critical pieces of information about the body. Regolith samples are excellent bulk samples because they normally contain all the key components of the local environment, albeit in particulate form. Furthermore, because this fine fraction dominates remote measurements, regolith samples also provide information about surface alteration processes and are a key link to remote sensing of other bodies. Studies indicate that a statistically significant number of nanogram-sized particles should be able to characterize the regolith of a primitive asteroid, although the presence of larger components (e.g., chondrules, calcium-aluminum-rich inclusions, large crystal fragments, etc.) within even primitive meteorites (e.g., Murchison) points out the limitations of using data obtained from nanogram-sized samples to characterize entire primitive asteroids. However, the most important asteroidal geological processes have left their mark on the matrix, because this is the finest-grained portion and therefore most sensitive to chemical and physical changes. Thus, the following information can be learned from this fine grain size fraction alone: (1) mineral paragenesis; (2) regolith processes; (3) bulk composition; (4) conditions of thermal and aqueous alteration (if any); (5) relationships to planets, comets, meteorites (via isotopic analyses, including O); (6) abundance of water and hydrated material; (7) abundance of organics; (8) history of volatile mobility; (9) presence and origin of presolar and/or interstellar material. Most of this information can be obtained even from dust samples from bodies for which nanogram-sized samples are not truly representative. Future advances in sensitivity and accuracy of laboratory analytical techniques can be expected to enhance the science value of nano- to microgram-sized samples even further. This highlights a key advantage of sample returns--that the most advanced analysis techniques can always be applied in the laboratory and that well-preserved samples are available for future investigations.

The instrument used was the Airborne Topographic Mapper (ATM), developed by the NASA Arctic Ice Mapping (AIM) group from the Goddard Space Flight Center's Wallops Flight Facility. In November, 1995, and again in May, 1996, these topographic surveys were flown as a functionality check prior to conducting missions to measure the elevation of extensive sections of the Greenland Ice Sheet as part of NASA's Global Climate Change program. Differences between overlapping portions of both surveys are compared for quality control. An independent assessment of the accuracy of the ATM survey is provided by comparison to surface surveys which were conducted using standard techniques. The goal of these projects is to make these measurements to an accuracy of + or -10 cm. Differences between the fall 1995 and 1996 surveys provides an assessment of net changes in the beach morphology over an annual cycle.

These retrieval techniques were developed with data from the total ozone mapping spectrometer (TOMS) instruments on American, Russian, and Japanese satellites. The sulfur dioxide retrievals have been validated against groundbased Brewer and COSPEC measurements. The ash mass retrievals are in agreement with AVHRR two-band infrared ash retrievals. Daily satellite monitoring has detected, tracked, and quantified SO (sub 2) emissions from a wide range of eruptive activity, from highly explosive to effusive types, and has produced an unprecedented 20-year record of global volcanism. Primary findings from the TOMS data are (1) observations of "excess sulfur" over that liberated during liquid-phase degassing have indicated the existence of a volatile phase in pre-erupted magma; (2) indirect evidence for co-erupted H2S gas from apparent increase in S02 mass in drifting clouds; (3) insights into the removal rates of SO (sub 2) from the atmosphere, interactions with co-emitted ash particles, and responses to meteorological conditions; and (4) potential operational application of sulfur dioxide and ash detection for aviation hazard mitigation.

The impact of coastal hazards depends on the proximity of human population to the coastal zone. Recently compiled population estimates are combined with a new continental digital elevation model in an attempt to quantify the global distribution of human population and occupied land area with respect to elevation and coastal proximity. The limited spatial resolution of the census data allows one to quantify some of the uncertainty in the spatial distribution of population. This provides a lower bound on the uncertainty in the resulting distributions but does not account for uncertainty in the census data or elevation data. Long-term records of relative sea level rise, tidal heights, and storm surge heights can be combined with global sea level rise estimates for a variety of climate change scenarios to estimate the approximate magnitude of vertical changes in local sea level. It is verified that large numbers of people live at low elevations near coasts but the uncertainties are too large to provide meaningful estimates of the number of people who reside in so-called "coastal zones" worldwide. The principal conclusion is that both the spatial distribution and the resolution of global data must be significantly improved before realistic quantitative assessments of the global impact of coastal hazards can be made.

Results show the laser altimeters are able to resolve subtle topographic features such as a gradual slope and to detect small transient changes in lake elevation. Crossover and repeat pass analyses of laser tracks indicate decimeter-level vertical precision is obtained over flat and low-sloped terrain for altimeter systems performing waveform digitization. Comparisons with complementary, ground-based GPS data at a site close to Bishop airport indicate that the laser and GPS-derived elevations agree to within the error inherent in the measurement and that horizontal locations agree to within the radius of the laser footprint. A comparison of the data at two sites, one where no change and the other where the maximum amount of vertical uplift is expected, indicates approximately 10 cm of relative uplift occurred 1993-1997, in line with predictions from continuous GPS measurements in the region. Extensive terrain mapping flights during the 1995 and 1997 missions demonstrate some of the unique abilities of laser altimetry; the straightforward creation of high resolution, high accuracy digital elevation models of overflown terrain, and the ability to determine ground topography in the presence of significant ground cover such as dense tree canopies. These capabilities make laser altimetry an attractive technique for quantifying topographic change of volcanic origin, especially in forested regions of the world where other remote sensing instruments have difficulty detecting the underlying topography.

In R. capsulatus, the Delta (super 15) N values for biomass during growth with N (sub 2) fixation and ammonia assimilation, relative to the N-source, ranged from -1.8 to -0.8 per mil and -12.3 to -10.2 per mil, respectively. In the cyanobacterium, Anabaena cylindrica, the Delta (super 15) N value for biomass resulting from growth on molecular nitrogen was -0.8 to -1.7 per mil relative to N-source. These values are similar to those observed for other microorganisms. Bacteriochlorophyll a in R. capsulatus was depleted in (super 15) N relative to biomass, whereas chlorophyll a in A. cylindrica was relatively enriched in (super 15) N.

While remote sensing of dust over the dark oceans is feasible, adequate techniques for remote sensing over the land still have to be developed. Here, similar to remote sensing of aerosol over vegetated regions, we use a combination of visible and mid-IR solar channels to detect dust over the desert. Analysis of Landsat TM images over Senegal taken in 1987 show that the surface reflectance at 0.64 mu m is between 0.54+ or -0.05 of the reflectance at 2.1 mu m, and reflectance at 0.47 mu m is 0.26+ or -0.03 of that at 2.1 mu m, surprisingly similar to relationships in non-desert sites. We also found that dust have only a small effect on the surface + atmosphere reflectance at 2.1 mu m over the desert. Therefore, in the presence of dust, we use the Landsat TM data at 2.1 mu m channel to predict the surface reflectance at 0.64 and 0.47 mu m. The difference between the satellite-measured reflectances of surface+atmosphere and the predicted surface reflectances is used to derive the dust-optical thickness tau at 0.64 and 0.47 mu m. Results show that tau can be derived within Delta tau = + or -0.5 for the range of 0 100 smaller median size. Parent-body source is suggested as the cause with orbits of parent bodies in orbits far from orbital resonances that transfer meteorites into Earth-crossing orbits within a few Ma.

Despite occasional low annual radiation levels or near-complete TL-saturation in certain samples, the combination of methods provided consistent OIS 7 dates (176-221 ka BP; penultimate interglacial stage) from the fragmented, second-oldest shore-parallel terrace (coastal "Montgomery" terrace in SW Louisiana and adjacent east Texas). This is the oldest TL- and OSL-dated Pleistocene terrace unit thus far. The method also distinguished them from landward-adjacent Late Pliocene (ca. 3.2 Ma) Citronelle/Williana and Sangamon (OIS 5); seaward-adjacent Prairie-"Beaumont" coastal terrace deposits. The latter produced dates in the east Texas and Mississippi coastal area in the 102-135 range. Most preliminary intermediate terrace samples from the Pearl, Amite, and Sabine Valleys dated in the 21-to-54 ka range. TL and OSL date clusters from eolian landforms (Late Quaternary dunes and late Holocene pimple mounds of probably wind-blown origin) identified several episodes of dry climate phases in a wide range of coastal locations. Luminescence dating was the only means to set dune generations apart. Sands from the Sangamonian Gulfport-Ingleside barrier ridgeplains, located along the Gulf shores of NW Florida, Alabama, and SW Texas (Aransas Refuge) were the likely sediment sources for numerous parabola- and other dune remnants, thus far dated 15-to-23 ka BP. These ages partly overlap with ages of certain SE Louisiana inland dune fields (16.8-28.8 ka). TL dating provided the sole means for age separation between the large late Pleistocene Alabama-NW Florida dune fields and the equally sizable and presently heavily vegetated latest Holocene SW Texas (Aransas, Ingleside area) dunes, previously thought as being of the same age range.

The goal of the mission is to return powdered or chipped samples from the surface (regolith?) of a small near-Earth asteroid (http://www.muses-c.isas.ac.jp/index.html). NASA is providing some support to the mission, and a few U. S. researchers serve on the Science Team (including the author). The spacecraft will leave Earth in 2002, and rendezvous with near-Earth asteroid 1998SF36 in 2005. Once in orbit, a rendezvous vehicle will separate from an orbiter. A "nano-rover" will drop from the former spacecraft, and hop around on the asteroid's surface making measurements and observing the collecting activities. The rendezvous vehicle itself will briefly touch down on the surface 2 or 3 times, each time firing a projectile to blast material from the surface. On the order of 1g of material will be collected into a horn-shaped receptacle at each site. Following collection, the rendezvous vehicle re-mates with the orbiting spacecraft for Earth return. In 2007, the samples are returned to Earth within a hermetically-sealed capsule, and flown to the ISAS lab, near Tokyo, for 1 year of preliminary investigation in Japan. During this time the samples will be available for analysis only in Japan, mainly by the Muses-C Science Team. However, following this initial period the samples will be made widely available, with approximately 10% of the sample mass coming to NASA's Johnson Space Center for curation and wide distribution to mineralogists, petrologists and other astromaterials workers. These missions will all provide samples to the general science community for detailed analyses following a relatively brief period of initial assessment by the mission science teams.

The patterns of these flow-related features reveal a history of discharge variations from the ice streams feeding the eastern part of the shelf. The most profound variations are visible in the track of rifts downstream of Crary Ice Rise, flow-stripe bends to the west of this ice rise and adjacent to Steershead ice rise, and changes in the northern margin of Ice Stream B. The track of rifts downstream of Crary Ice Rise indicates that the ice rise has existed for at least 700 years. The character of this track changes about 350 km downstream, indicating a rearrangement of flow patterns about 550 years ago. The large bulge in the flow stripes to the west of Crary Ice Rise is shown in detail, with bent flow stripes extending for several hundred kilometers along flow; this feature formed from the south, possibly due to a change in the discharge of Ice Stream A. The AVHRR image documents a complex history associated with the shutdown of Ice Stream C, with changes in the margins of Ice Stream C and the northern margin of Ice Stream B, and the grounding of Steershead ice rise with an associated bending and truncation of flow stripes. Landsat imagery shows a region that appears to be actively extending just downstream of the ice rise, as the shelf continues to respond to recent changes in ice-stream discharge. We present a four-stage flow history which accounts for the features preserved in the ice shelf.

The GCMD can be searched using controlled keywords or free-text to retrieve descriptions (metadata) about data pertaining to a wide range of Earth science topics covering geology and paleoclimatology, ecosystems and biosphere, hydrosphere and oceans, agriculture science and human dimensions of climate change, and atmospheric science. The metadata descriptions within the GCMD include the following elements: data set citation, investigators, temporal and geospatial coverage, data set resolution, contact information, and a summary, as well as keywords describing Earth science parameters, geographic locations, field campaigns, and sources and sensors used to collect the data. More complex searches can be performed using GCMD interfaces and the results further refined by the use of temporal and spatial constraints. Data set descriptions can be provided to the GCMD using on-line metadata authoring tools available on the GCMD web site. The GCMD is employing a Document Type Definition (DTD) and the eXtensible Markup Language (XML) for interoperability between homogeneous and heterogeneous Earth science database systems. Geoscience data providers are encouraged to submit metadata records of their data collection to promote awareness of the data and provide the potential for an archive of citation data parallel to published journal citations. The GCMD is collaborating with the American Geophysical Union and Elsevier to explore the possibility of using the Directory as a resource discovery tool for published data associated with peer-reviewed electronic publications. Collaborations have been initiated with the U. S. Department of Agriculture (USDA), the U. S. Geological Survey (USGS) and other national and international geoscience organizations including the Joint Committee on Antarctic Data Management (JCADM) and the United Nations Environmental Programme (UNEP). These and other collaborations allow users to search subsets of the GCMD as they pertain to the collaborating institution.

Estimates of the original rim diameter range from approximately 20 km to approximately 24 km. The target sequence comprises a approximately 1750 m thick series of predominantly carbonate rocks of Lower Paleozoic age, underlain by Precambrian metamorphic basement. Detailed geological mapping carried out during the 1999 and 2000 field seasons of the NASA-led Haughton-Mars Project (HMP), has revealed important evidence regarding the modification stage of complex impact crater formation. The periphery of the Haughton impact structure is characterized by a zone of interconnected concentric and radial faults. Fault-bounded blocks of originally gently dipping ( approximately 5 degrees ) Allen Bay Formation carbonates are tilted at various angles ( approximately 10 degrees to 90 degrees ), dipping both in towards, and out from the centre of the structure. Fault planes displaying slickenside lineations and displacement indicators are occasionally exposed along steep valley walls, and are typically associated with huge thicknesses of fault breccia ( approximately 5 m to 80 m). In the northwest and northeast, the majority of concentric faults are listric and normal extensional faults, dipping in towards the centre of the structure. However, in the south, there appears to be a complex interaction of reverse faults, listric and normal extensional faults. In contrast, the majority of radial faults preserve evidence for oblique strike-slip movement. This work suggests that the tectonic modification of the Haughton crater involved the complex interaction of concentric and radial faults. It is important to note that the kinematics and orientation of concentric faulting vary across the structure.

This flow is reflected in nonradial ejecta trajectories expressed by an asymmetric ejecta curtain with enhanced debris downrange at lower angle trajectories and reduced debris uprange with higher angle trajectories. As the crater continues to grow, the curtain becomes more symmetric and flow becomes more radial. This transition from non-radial to radial flow occurs very early in crater formation and is expressed in the final ejecta blanket morphology by changes of thicknesses with azimuth around the crater. Three dimensional particle imaging velocimetry is being used to document this early-time transition from non-radial to radial flow within the ejecta curtain using the NASA-Ames Vertical Gun Range. Velocity data for particles moving within the ejecta curtain are obtained as well as cross-sectional images of the ejecta curtain as it grows. Data are collected as early as 2 milliseconds after impact. Here we compare derived ejecta velocity scaling relations for vertical impacts and impacts at a 30 degree angle from horizontal. Differences at 30 degrees between uprange, downrange and lateral ejecta behavior are discussed.

The Earth=s moon, with its low level of endogenic geologic activity, provides the best record of (near) pristine craters and forms the natural baseline for determining the morphology and morphometry of impact craters. It has been well recognized that, for a given impact event, surface gravity affects the nature of the final crater through its influence on ejection and subsequent modification of the initial transient cavity, created by the cratering flow-field. There is also a secondary effect, which is less well recognized; namely, that the spatial extent of particular shock metamorphic effects can also affect the final crater, through changes in the physical properties of the target rocks. This is not a function of gravity but is controlled, for given impactor and target types, by the physical dimensions of the impactor and impact velocity. Relatively small, low velocity impacts in low surface gravity (e.g., asteroidal-asteroidal impacts) will produce craters with the minimal changes in target rock properties due to shock. Conversely, very large, high speed impacts in high surface gravity (e.g., basin-forming impacts on the early Earth) will produce craters, which can be severely affected by changes in target rock properties due to shock. The equivalent of basin-forming impact on the moon would not produce an equivalent morphology on the early Earth.

Petrographic characteristics have demonstrated that some of the weathering features are of martian origin. Alteration products and secondary minerals in the martian meteorites contain important clues to both the terrestrial and the martian near-surface histories of the rocks. We are doing detailed FE-SEM, EDS, and TEM studies of the martian meteorites, currently concentrating on the observed falls Nakhla (Egypt, 1911) and Shergotty (India, 1865). The petrologies of these two meteorites are somewhat different: Nakhla is a clinopyroxenite and Shergotty is diabasic. Their weathering features, however, are remarkably similar to each other. Natural fracture surfaces in both samples commonly have silicate dissolution features along with evidence of incipient phyllosilicate formation. In addition, many oxide and sulfide grains appear to be altered by oxidation. One of the distinctive characteristics of Nakhla is the presence of alteration veins in olivine and pyroxene, consisting of intermixed phyllosilicates, Fe oxides, and unweathered mineral fragments. Shergotty also contains secondary veins of silicate material, although they are less abundant than those in Nakhla; further study is needed to determine whether the characteristics of the veins are like the Nakhla veins. The other major similarities between the two meteorites are the types and habits of the secondary salts present. The most abundant salts are NaCl and Ca-sulfate, clear evidence of an evaporitic weathering environment. Because the secondary assemblages in Nakhla and Shergotty are so similar, and because the two meteorites have had different terrestrial histories, it is probable that most of the observed secondary features and minerals are the result of weathering on Mars. Perhaps an effective way to identify martian weathering features in other martian meteorites would be to look for meteorites that also have similar weathering assemblages but different terrestrial histories.

Isotopes help to discern the impacts of geological, environmental and biological processes upon the evolution of these cycles. For example, (super 13) C/ (super 12) C values of coeval sedimentary organics and carbonates give global estimates of the fraction of C buried as organics (Forg), which today lies near 0.2. Before oxygenic photosynthesis arose, our biosphere obtained reducing power for biosynthesis solely from thermal volatiles and rock alteration. Thus Forg was dominated by the mantle redox state, which has remained remarkably constant for >3 Gy. Recent data confirm that the long-term change in Forg has been small, indicating that the mantle redox buffer remains important even today. Oxygenic photosynthesis enabled life to obtain additional reducing power by splitting the water molecule. Accordingly, biological organic production rose above the level constrained by the mantle-derived flux of reduced species. For example, today, chemoautotrophs harvesting energy from hydrothermal emanations can synthesize at most between 0. 2X10 (super 12) and 2X10 (super 12) mol C yr-1 of organic C globally. In contrast, global photosynthetic productivity is estimated at 9000X10 (super 12) mol C yr (super -1) . Occasionally photosynthetic productivity did contribute to dramatically-elevated Forg values (to 0.4 or more) as evidenced by very high carbonate 13C/12C. The interplay between biological, tectonic and other environmental factors is illustrated by the mid-Archean to mid-Proterozoic isotopic record. The relatively constant 13C/12C values of Archean carbonates support the view that photosynthetically-driven Forg increases were not yet possible. In contrast, major excursions in (super 13) C/ (super 12) C, and thus also in Forg, during the early Proterozoic confirmed the global importance of oxygenic photosynthesis by that time. Remarkably, the superplume event at 1.9 Ga did not trigger another major Forg increase, despite the favorable conditions for organic burial that were evidenced by elevated sea levels and higher black shale abundances. Perhaps those superplume-rated processes that favored enhanced organic burial were offset by the ability of mantle-derived redox buffering, which was enhanced during the superplume event, to limit excursions in Forg.

America (Chihuahua and W. Texas) AN - 51971261; 2003-046562 AB - Ancestral Rocky Mountain uplifts in Chihuahua and west Texas (28 to 33 degrees N, 102 to 109 degrees W) include the Florida-Moyotes, Placer de Guadalupe-Carrizalillo, Ojinaga-Tascotal and Hueco Mt. blocks, as well as the Diablo and Central Basin Platforms. All are cored with North American Proterozoic crystalline basement rocks and host correlative Paleozoic stratigraphic successions. Pre-Late Paleozoic deformational, thermal and metamorphic histories are also similar. Sierra del Cuervo, with a foundation of North American Precambrian basement rocks, may also be an Ancestral Rocky Mt. uplift, but the sedimentary strata that would confirm or refute that assignment are absent. On the basis of lithostratigraphic and isotopic data the Aldama Platform, Devils River uplift, and part or all of the Coahuila terrane (sensu Coney) are accreted blocks that originated apart from North America. The latter two record thermal histories that are distinct from that of southern North America; notable elements include Silurian and Devonian metamorphic events. Metasedimentary and metaigneous strata of virtually identical compositions, metamorphic grades, and isotopic ages are known from the Acatlan-Yucatan-Chiapas complexes; boulders of such rocks are entrained in Carboniferous synorogenic flysch in the Marathon Basin. About 30 kilometers northwest of the boundary of North America, as defined on the basis of lead isotope ratios, the southernmost Ancestral Rocky Mt. uplifts (Placer de Guadalupe-Carrizallilo and Ojinaga-Tascotal blocks, Diablo Platform and Central Basin Platform) are terminated along a line trending N35 to 40 degrees E. That line also marks the southern edge of Sierra del Cuervo, whatever its status as an Ancestral Rocky Mt. block. Deformation continued at this end of the Ancestral Rocky Mt. chain and along the southern margin of North America through Permian time.

As climate has warmed in the Antarctic Peninsula region, melt-season duration and the extent of ponding have increased. Most break-up events have occurred during longer melt seasons, suggesting that meltwater itself, not just warming, is responsible. Regions that show melting without pond formation are relatively unchanged. Melt ponds thus appear to be a robust harbinger of ice-shelf retreat. We use these observations to guide a model of ice-shelf flow and the effects of meltwater. Crevasses present in a region of surface ponding will likely fill to the brim with water. We hypothesize (building on Weertman (1973), Hughes (1983) and Van der Veen (1998) that crevasse propagation by meltwater is the main mechanism by which ice shelves weaken and retreat. A thermodynamic finite-element model is used to evaluate ice flow and the strain field, and simple extensions of this model are used to investigate crack propagation by meltwater. The model results support the hypothesis.

This salar is the largest salt flat in the world and is a conspicuous remnant of the late Pleistocene Lake Minchin-Tauca. There are two main objectives for this project: (1) to produce a seismic stratigraphic record for Pleistocene deposits within the southern basin of the Altiplano by imaging interbedded layers of lacustrine marls and salar salts down to depths of 300-500 meters and (2) to document the extent to which the Quaternary lake stratigraphy is affected by neotectonic deformation in the form of either isostatic rebound or active faulting. The profiles were designed to cross the site of the 220 meter deep corehole drilled by Baker and others (AGU 1999 Fall Meeting, EOS, 80, F531) within the Salar de Uyuni in June 1999 and will be tied to the stratigraphy seen in the core. They should also provide a more regional stratigraphic framework in which to place the core data and help identify any structural or stratigraphic complexities within the salar portion of the lake stratigraphy. The seismic data were acquired using high-resolution seismic equipment from IRIS PASSCAL during two field excursions in July and August 2000. A jackhammer was used as the source, providing surprisingly high-frequency data (up to 800 Hz) down to depths of at least 300 m. Data quality is quite good despite the 2-10 meter thick surficial salt layer and some very windy conditions. Velocity in the salt layers is from 3000 to 4000 m/s near the surface. These high velocity salt layers generate peculiar looking shot records, with high-velocity direct waves, groundroll, and possible guided waves, but reflections can easily be identified on the near traces from very near the surface to depth.

The objective of the joint study is to better understand earthquake hazard associated with the subduction of the Pacific plate beneath Kodiak Island, Alaska, while involving students and their teachers in the research. This enables them to make connections between the scientific investigation, their environment and the science classroom. Several methodologies were used to prepare the students for both a general understanding of the plate tectonics and to meet rigid scientific protocols for setting up GPS antennae and data collection. The scientists taught students the fundamentals of satellite geodesy and GPS, and trained them to set tripods, mount GPS antennae, monitor the GPS receivers, and keep data logs. Students also read and discussed papers on the plate tectonics of the area with their teacher and members of the NASA science team. In pre-experiment field trips students examined the Prince William and Chugach terranes, their geologic history, and structural features. Following the first experiment in 1995, two participating students gave a lecture in Linscheid's earth science classes by using a computer program that showed the subduction process (TASA) and a hands-on lab that demonstrated how GPS works. Cooperative field observations were conducted again in the summers of 1997 and 1999. Over the 1993-1999 time period we estimated the horizontal velocity of the geodetic sites to range from about 20 mm/yr near the eastern coast to 7 mm/yr further inland. Also in 1999 a permanent, continuously operating GPS site was built on Kodiak Island (KODK) that is part of international GPS monitoring network.

The shorelines which form as level surfaces while large lake loads are present, are arched upwards in the center of the basin during more arid times, when the loads are much reduced. A sufficiently large lake will thus both produce and record vertical crustal deformation, the spatio-temporal pattern of which provides information on long term strength. It is instructive to compare two such lake systems: Lake Minchin on the Bolivian Altiplano, and Lake Bonneville in the eastern Great Basin of Utah. The two lake systems are similar in many important regards. Both lakes attained their maximum extent at roughly the same time, at about 15 ka. Their maximum sizes were quite similar, with Bonneville attaining a surface area of 45,500 km2 in a drainage basin of 128,400 km2, and Minchin attaining an area of 60,300 km2 in a basin of 201,200 km2. In contrast, Bonneville was substantially deeper, with a maximum depth of 410 m and 80 m of rebound on the highest shoreline, compared to Minchin's maximum depth of 130 m and 30 m of rebound. Though both basins contain large areas of low relief, the Minchin basin is appreciably flatter floored. The lake attained 1/3 and 1/2 of its total surface area at water depths of only 10 and 24 m, respectively. Proper utilization of the crustal deformation pattern to obtain constraints on rheology of the crust and upper mantle requires accurate knowledge of the loading history. This in another area in which Minchin and Bonneville presently differ. The Bonneville lake level history for the past 40 kyr is very well constrained by a large number of radiocarbon dates. In contrast, the Minchin history is only rather poorly understood at present. In addition, the rebound pattern in the Bonneville basin is constrained by several hundred elevation measurements on 4 distinctive shorelines (Stansbury, Bonneville, Provo, and Gilbert). In contrast, the rebound pattern in the Minchin basin is only crudely represented by elevation measurements at 15 locations.

The pattern of velocity and strain rate shows the development of Ice Stream D, the major flow into which originates south of Byrd station and follows the course of a deep bed channel. Plotting of the driving stress vs the ratio of velocity and ice thickness identifies the onset of streaming flow (roughly 140 km downstream of Byrd station) as a transition between deformation flow and sliding flow. Along the kinematic center line of the developing ice stream, the ice rheology is linear at stresses below 0.6 bar, and appears temperate at the base well before the onset of streaming is reached. The onset corresponds to a maximum driving stress of 0.8 bar. It occurs downstream of a slight increase in longitudinal strain rate where stronger along-flow lineations are apparent in Landsat imagery, and after the ice has passed the center of an overdeepening in the bed channel. No current deviation from equilibrium is detected in this region, but a set of flow stripes misaligned with present flow indicates significant changes in flow have occurred in the past.

These are potential modern day analogs to some ancient stromatolitic structures. We have used a JEOL 6430 Field Emission Gun Scanning Electron Microscope (FEGSEM) equipped with light element electron dispersive X-ray spectrometry (EDS) to examine the stromatolites for the presence and composition of biogenic features. Additionally, 16S rRNA analyses indicate the presence of five sulfur reducing genera of bacteria. Our SEM analyses show that rod-like and spheroid-shaped features are abundant on fractured stromatolite surfaces. Spheroidal features are the most common, with three populations or sizes: large (mean size 5.5 microns), medium (mean size .55), and small (mean size .13 microns). The surface textures are mostly rough (i.e. wrinkled). The largest spheres are isolated from the other two populations; some have surface indentations. The medium and small are closely associated and commonly embedded with biofilm. The biofilm is composed of thick filaments and web-like, vesiculated film. It is likely that the spheres are the mineralized (or fossilized) remains of coccoid microbes, including one of the sulfur reducing bacteria. The large and medium-sized spheres are morphologically similar to normal-sized microbes. The small spheres may be analogous to nanobacteria, or may be biologically mediated precipitates. It is unlikely that they are inorganic due to their intimate association with medium-sized spheres and biofilm. Chemical analyses may provide additional insights into the usefulness of these tiny spheres as physical biomarkers.

Perhaps differences between biologically and inorganically weathered surface textures could be used as biosignatures for future application to extraterrestrial materials such as Martian meteorites. We are experimentally weathering small (<2 mm) fragments of olivine from San Carlos (central Arizona) by both inorganic and biological means, and are documenting the results with a JEOL 6340F field emission gun scanning electron microscope (FE-SEM) equipped with an IXRF energy-dispersive X-ray spectrometry (EDS) system. Inorganic experiments were performed by heating olivine in water at 200 degrees C and 98 degrees C; samples at each temperature were heated for 24 and 48 hours. Initial results indicate that in spite of the lack of cleavage in olivine, alteration is commonly controlled crystallographically. For biological experiments, bacteria were obtained from groundwater in the Columbia River Basalt, Washington, by attaching a sterile flow-through device (containing olivine), to a well head to collect natural subsurface microbes. Olivines were placed in enrichment media for both aerobic and SRB weathering, and are being removed from the media (and fixed in glutaraldehyde) at regular intervals. Thus far, we have preliminary SEM/EDS results for aerobic and SRB weathering samples from T = 0, 24 and 48 hours. All these samples show the presence of some biotic matter, which is found in small clusters near each other. The biotic material also appears to be associated in areas of olivine with rough surface textures. The olivine surface textures are consistent with those on the inorganically weathered olivines, except that the biotic samples also have finer etching and dissolution textures on the scale of tens to hundreds of nanometers (in the same areas as the rough surface textures). Preliminary data suggest that the bacteria influence the surface textures by extracting Fe, and possibly Mg, from the olivine substrate.

This means that ALL students should have at least a basic knowledge of climate concepts, as well as some understanding of the methods that scientists and policy makers are relying on to forecast future climate change. Furthermore, if we can bring students into contact with the actual tools-of-the-trade at a much earlier stage of their education we will be better preparing the next generation of geoscientists. The 3-dimensional computer simulations known as global climate models (GCMs) are a primary tool used in climate change research. Most operational GCMs, however, still reside at institutions with large-scale computational resources (primarily national labs). Thus, few students today have access to GCMs prior to graduate school (and many not even then). Graduate geoscience programs must, therefore, train students in the use of fundamental tools and, more ominously, the public's lack of familiarity with the basic tools and concepts of climate science breeds a distrust of important scientific findings. Recently we ported two of NASA's GCMs to run on the type of inexpensive computers (Mac OS) that can be found in many high school labs. A user-friendly interface (EdGCM) applied to these complex models helps students explore the fundamentals of climate science while employing the identical tools that are used in national climate research programs. While this allows for a wide range of simple climate studies, such as the role of the sun in warming the planet, it also permits in-depth investigation of topics such as the link between anthropogenic greenhouse gases and global warming. "Canned" scenarios investigate modern climate, past climates, and future global warming. Significantly, however, teachers can easily construct their own scenarios (real or fantastic) to cover a broad array of climate topics, not the least of which might be the use and limitations of current, state-of-the-art GCMs. JF - Abstracts with Programs - Geological Society of America AU - Chandler, Mark A AU - Anonymous Y1 - 2000 PY - 2000 DA - 2000 SP - 429 PB - Geological Society of America (GSA), Boulder, CO VL - 32 IS - 7 SN - 0016-7592, 0016-7592 KW - EdGCM KW - general circulation models KW - high school KW - three-dimensional models KW - data processing KW - education KW - simulation KW - climate change KW - models KW - K-12 education KW - future KW - policy KW - climate KW - 22:Environmental geology UR - http://libproxy.lib.unc.edu/login?url=http://search.proquest.com/docview/51888807?accountid=14244 L2 - http://vb3lk7eb4t.search.serialssolutions.com/?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQ%3Ageorefmodule&rft_val_fmt=info:ofi/fmt:kev:mtx:journal&rft.genre=article&rft.jtitle=Abstracts+with+Programs+-+Geological+Society+of+America&rft.atitle=EdGCM%3B+bringing+a+NASA+global+climate+model+into+the+classroom&rft.au=Chandler%2C+Mark+A%3BAnonymous&rft.aulast=Chandler&rft.aufirst=Mark&rft.date=2000-01-01&rft.volume=32&rft.issue=7&rft.spage=429&rft.isbn=&rft.btitle=&rft.title=Abstracts+with+Programs+-+Geological+Society+of+America&rft.issn=00167592&rft_id=info:doi/ LA - English DB - GeoRef N1 - Conference title - Geological Society of America, 2000 annual meeting N1 - Copyright - GeoRef, Copyright 2012, American Geosciences Institute.

Proposed changes, however, require resources for equipment, supplies, new curricula, and teacher preparation. Willingness of the teachers to adopt new curricula is perhaps the most important factor that generates meaningful change. Too often, however, other factors negate willingness. The lack of resources usually prevent change. With resources from a NASA-EPSCoR grant, changes were implemented in the earth science curricula at Sequoyah High School, Tahlequah, Oklahoma. The focus of the class became the watershed, an integrated unit that functions as an open system. Measuring stream flow over time demonstrates how excess precipitation (and groundwater) exit the system. Students learn how many variables in the watershed influence stream flow. Portable current meters were used to measure the velocity of the water. Students observed how velocity and discharge varies with the channel cross-section and bed material of the channel. Handheld GPS receivers provide accurate locations on Earth which can be translated into map positions where streams were sampled. Students have eagerly participated in these field activities (examples to be handed out). They also learned to collect water samples and assess variables related to quality. Follow-up integration of concepts and data from a variety of sciences in the classroom then demonstrates that surficial change is dynamic and observable compared to simply learning about change through reading.

Most of the earlier studies did not include scanning electron microscopy, methods of fossilization, or the sediment types with which the microbes were associated. In this study we are analyzing detrital and evaporite sediments from the Dead Sea in order to identify putative fossilized organic remains, the dominant microbial substrate, and possible biomarkers. The probable microbial remains are identified using field emission scanning electron microscopy (FE-SEM), energy dispersive x-ray spectrometry (EDS), fluorescent microscopy. X-ray diffraction (XRD) is used to identify the minerals composing the sediment. The samples are composed primarily of halite, quartz, and orthoclase feldspar. The quartz and orthoclase are well rounded and sand-sized. The putative fossilized remains (2 microns) vary from elliptical to an ovoid shape, and generally incrust on halite rich evaporite sediments. EDS analysis indicates that calcium is the dominant fossilization cation; magnesium is occasionally detected. A dominant microbial form possesses filaments that have net-like extensions and appear to connect the probable microbes. The extensions are forked or flattened near the putative fossilized remains.In conclusion, our initial studies indicate that microbial fossilization is limited, and that it does not reflect the reported microbial diversity. The possible fossils are all similar morphologically, and difficult to identify taxonomically. The microbial remains are associated primarily with halite and elevated levels of calcium, a metallic ion that is nucleated by microbes. Magnesium may also be a possible indicator of microbial presence as it is used for assembling ribosomes, polar heads of the membrane phospholipids.

These tools, written in the Research Systems IDL programming language (http://www.rsinc.com), provide display and graphical user interface elements for controlling data visualization functions such as zooming, contouring, profiling, color table adjusting with tools for measuring slope, distance and height. Initially designed for use by planetary geologists, these tools have been successfully used by high school and undergraduate students to analyze the topographic characteristics of Mars in support of several educational research projects. One of the programs, "gridview", is used to analyze gridded data products. The intuitive interface of this program allowed students to quickly zoom into their area of interest, visualize the data and extract the topographic measurements they needed for their studies. Another program, "molazoom", is used to analyze high resolution MOLA profile data. These programs can be used in an educational setting to help teach students topographic analysis techniques or as an aid in specific research projects. IDL, with its large library of data visualization and manipulation procedures, is an excellent programming environment for the rapid development of visualization programs. However, IDL is an interpreted language that requires that the user have an IDL compiler to execute programs. A major difficulty in applying this technology in an educational setting is the cost of the IDL compiler, which is approximately $1500 for a single CPU license. However, Research Systems does offer faculty and staff of degree granting institutions several discount programs, including a special student version of IDL for $79. To help alleviate this restriction these programs have been written so they will function in the 'free' IDL demonstration mode which has a time limit of 7 minutes per session with some output options disabled. These programs will be available for download on the web at http://denali.gsfc.nasa.gov/mola.

A quarry exposes 26 m of the targeted Upper Cretaceous Campeche carbonate platform bedrock, (Barton Creek Formation), overlainby 16 m of KT impact ejecta (Albion Formation, composed of a lower 1 m-thick Spheroid Bed and an upper 15 m-thick Diamictite Bed). The uppermost surface of the Barton Creek Formation was subaerially exposed at the time of the KT impact, as indicated by negative covariation trends in d13C and d18O and a brecciated paleosol on the uppermost surface. The Spheroid Bed is composed of a fine dolomite matrix, clays (devitrified melt glass), dolomite spheroids, shocked quartz, and striated clasts of dolomitized marine limestone. Dolomite and clay 87Sr/86Sr reach a distinct symmetrical maximum in the middle of the Spheroid Bed, which reflects primary changing the source of ejecta during the earliest stages of impact. The dolomite spheroids exhibit a unique non-radial vermicular texture in plane-light and cathodoluminescence, suggesting that the process of spheroid formation is more similar to that of chondrules than accretionary lapilli. The overlying Diamictite Bed is composed of a fine dolomitized matrix, dolomite spheroids, clays, and striated and dolomitized limestone blocks and pebbles excavated from a depth of up to 2 km within the Campeche platform. Dolomite replacement of the clay indicates that the complex sequence of dolomitization and calcitization events comprising the Spheroid and Diamictite Beds are the product of post-depositional water-rock interactions and not primary impact-related crystallization.

A database of accumulation values for 5365 gridpoint locations with 50 km spacing is interpolated from the isopleth map, giving a bulk accumulation of 2151 Gt a (super -1) and a mean of 159 kg m (super -2) a (super -1) for an area of 13.53X10 (super 6) km (super 2) . Following the implementation of deflation and ablation adjustments applicable to sectors of the coastal zone, the accumulation values are reduced to 2020 Gt a (super -1) and 149 kg m (super -2) a (super -1) . The new accumulation distribution is compared with another recent distribution, which was based on essentially the same field data using different analysis and interpolation criteria. Differences between the distributions are assessed using residuals for the 50 km gridpoint locations and by comparing average accumulation values for 24 drainage systems. The assessment based on residuals indicates that the two distributions show patterns of accumulation that are coherent at the continental scale, a shared attribute underscored by a small mean residual value of 6 kg m (super -2) a (super -1) (a difference of or =22%) for six systems that collectively comprise approximately 4/10 of the ice-sheet area and 3/10 of the accumulation.

Branches of the network follow valleys in basal topography, but not all valleys contain tributaries. We investigate the circumstances favoring tributary flow upstream of Ice Streams D and E, using a combination of observation and numerical modelling. No consistent pattern emerges. The transition from tributary to ice-stream flow occurs smoothly along the main tributary feeding into the onset of Ice Stream D, with ice thickness being relatively more important upstream, and sliding being relatively more important downstream. Elsewhere, the downstream pattern of flow is more complicated, with local increases and decreases in the contribution of sliding to ice speed. Those changes may be due to variations in basal water storage, subglacial geologic properties or a combination of the two.

(sub 6) . Combined with observed changes in the Earth's rotation pole and global sea level rise, these observations provide a powerful constraint on aggregate mass transport within the Earth's systems. Analysis to date indicates that both the Antarctica and Greenland ice sheets are nearly in mass balance when the forward models are used without any accommodation for correction terms. SLR and DORIS tracking of TOPEX/POSEIDON have been combined with the SLR tracking of LAGEOS, KAGEOS-2, Starlette, Stella, and Ajisai previously used to estimate the geopotential rates. Estimates of scale correlations to the forward models are also used to gain insight into the relative performance of these models and improve the estimate of the ice balances.(modified journ. abstr.)

In middle and high latitudes, the isotope concentrations are linearly related to annual mean temperature at the site. This assumes that the spatial relationship holds in time at a given location as the location undergoes climatic changes. This assumption is examined and findings indicate that the paleothermometer is biased by seasonality of precipitation and other factors. Deuterium data from Antarctica and O-18 ratios are studied from the Greenland ice sheet as two models (ECHAM and GISS) are forced with the boundary conditions of the Holocene at 6,000 BP.

Given the likelihood of a manned mission to Mars sometime within the next 15 years, it becomes critical to drive the design of space suit systems so that the resulting suits are robust, and support the kinds of activities that geologists will carry out on the terrestrial planets and satellites. There are a number of key physiological and physical constraints that drive space suit design: 1) humans have to breathe oxygen in a fairly narrow range of partial pressures; 2) humans live in a pressurized environment, and pressure must be maintained at a roughly equal level over the entire body; 3) humans generate, and must get rid of, carbon dioxide, waste gasses, and heat; and, 4) human joints and appendages are designed for specific kinematics of movement that must be accommodated by suit design. During the last 3 years, Johnson Space Center has been carrying out field activities in geologically relevant terrains testing a variety of space suit designs using a field geologist as the test subject (crash test dummy). These field tests have established the "kinematics" of geologic field work, both suited and shirt-sleeve, and have developed minimum mobility requirements for future space suit system design for geologic field work. In addition, field tests have been conducted to determine the best use of a combined robotic-rover/field geologist team. These tests have shown that suited geologists are more agile in typical field terrains than the present rover designs. However, they have also shown that the rover/geologist team is a valuable one for field geology, and should be developed as a standard field operations mode in future planetary exploration.

Rovers are mobility systems for carrying instrumentation to investigate targets of interest and can perform geologic exploration on a distant planet (e.g. Mars) autonomously with periodic command from Earth. For nearby sites (such as the Moon or sites on Earth) rovers can be teleoperated with excellent capabilities. In future human exploration, robotic rovers will assist human explorers as scouts, tool and instrument carriers, and a traverse "buddy". Rovers can be wheeled vehicles, like the Mars Pathfinder Sojourner, or can walk on legs, like the Dante vehicle that was deployed into a volcanic caldera on Mt. Spurr, Alaska. Wheeled rovers can generally traverse slopes as high as 35 degrees, can avoid hazards too big to roll over, and can carry a wide range of instrumentation. More challenging terrain and steeper slopes can be negotiated by walkers. Limitations on rover performance result primarily from the bandwidth and frequency with which data are transmitted, and the accuracy with which the rover can navigate to a new position. Based on communication strategies, power availability, and navigation approach planned or demonstrated for Mars missions to date, rovers on Mars will probably traverse only a few meters per day. Collecting samples, especially if it involves accurate instrument placement, will be a slow process. Using live teleoperation (such as operating a rover on the Moon from Earth) rovers have traversed more than 1 km in an 8 hour period while also performing science operations, and can be moved much faster when the goal is simply to make the distance. I will review the results of field experiments with planetary surface rovers, concentrating on their successful and problematic performance aspects. This paper will be accompanied by a working demonstration of a prototype planetary surface rover.

Conditions for this experiment were created to mimic carbonate mineral precipitation observed in Arctic river icings (aufeis). From these data, we gauge whether this mechanism is capable of producing C-13-enriched carbonates similar to those found in the Martian meteorite ALH84001. Carbonates from ALH84001 were shown previously to contain the most C-13-enriched isotopic compositions yet reported for an SNC (Mars) meteorite ( approximately +41 per mil [VPDB]). Previously, we reported the successive C-13 enrichment of cryogenic calcite, formed by repeatedly freezing and thawing a calcium bicarbonate-rich solution over time. For the present study, we examine calcite precipitation during aufeis formation. Aufeis forms as a mass of surface ice in cold regions by successive freezing of sheets of water that originate from groundwater or surface water. To simulate this process we injected four 5 ml aliquots of a calcium bicarbonate solution (made by prolonged bubbling of pure carbon dioxide gas through a saturated solution of calcium hydroxide held at +3 degrees C) into a stoppered 250 ml glass bottle held at 18 degrees C. Each injected aliquot was allowed to freeze before a subsequent injection. The entire frozen mass was melted and precipitated calcite was collected by filtration for isotopic analysis. The carbon isotopic composition of the cryogenic calcite (-13.4) was approximately 9 per mil greater than the original bicarbonate solution (-22.5), indicating that a kinetically-controlled C-13 enrichment occurred during the formation of our simulated aufeis-produced calcite. These data suggest that calcite produced during the mechanism of aufeis formation could potentially explain the presence of C-13-enriched carbonates on Mars.

In this study, we use Mars Orbiter Laser Altimeter (MOLA) data to investigate a section of MFF between 5S-5N and 175-185E that contains a series of parallel northeast/southwest trending ridges and valleys unique to the area and the MFF formation. While recent work based on Mars Global Surveyor data suggests that eolian or volcanic airfall deposits may be the most likely origins, the unusual nature of the ridges also prompted recent suggestions that they are polar deposits. The ridges and valleys overlie a approximately 100 m thick resistant unit that extends from 167E to 180E. While the unit is locally mapped as MFF, at its eastern edge it becomes indistinguishable from previously mapped Hesperian units (Hnu). The unit appears to erode from a coherent plain into mesas and then knobs. Sediments obscure its contact with the Elysium Plains. On top of the resistant unit, the ridges have an average height of 250 m with a maximum of 300 m. Ridge peaks are 18-25 km apart with average slopes of 1.5 deg. on both the north and south facing sides. Both valley bottoms and ridgelines show a regional slope to the northwest. The topography of the ridges is not consistent with marine terraces, as there are no apparent topographic steps. Fluvial channels also seem unlikely, as valleys run perpendicular to the regional slope, show no uniform flow direction, and sometimes form closed basins. The area also shows no evidence of the layering and asymmetric slopes found in polar deposits, although the rolling nature of the topography is grossly similar. Interestingly, the Viking and MOC images reveal a windswept surface covered by small-scale yardangs very similar to other MFF localities. However, the ridges themselves appear to be perpendicular to the apparent wind direction indicated by other local MFF features, making an eolian origin for the ridges complex. While the local topography helps to constrain the probable origins of these ridges and valleys, additional information is necessary to explain their origins completely.

AN - 50298330; 2003-014683 AB - The correlation between terrestrial hematite and water lain deposits has strong implications for the recent discovery of several large hematite deposits near the equator of Mars (1). On Earth, microbial activity has been documented in association with hematite deposits (banded iron formations). In view of this association, we have investigated hematite-fossilized microbial remains from the Gunflint Formation as analogs for possible microfossils in the hematite deposits on Mars. The 2.0 Ga Gunflint Formation contains many microbial fossils (2), preserved in chert and, in some cases, hematite. The sample we investigated is a silicified iron stromatolite from a shallow water depositional facies. The biofilm layers and filamentous and coccoidal microfossils have been predominantly mineralized by hematite and silica. They were investigated using a combination of methods including optical and scanning electron microscopy, electron microprobe studies, and x-ray diffraction. Three main interactions between bacteria and hematite have been observed: 1) an intimate association between hematite crystals and biofilm, 2) biofilm and bacteria impregnated by hematite and silica, and 3) hematite crystals containing carbon-rich inclusions.The relationship between biofilm and microorganisms and hematite deposition has important implications for the origin of banded iron formations. Our observations support the influence of the Proterozoic biomass on the precipitation of hematite in the Gunflint Formation. Understanding of the hematite-rich area of the Gunflint Formation has wider implications for the origin of Precambrian iron deposition in general and possibly for the formation of iron deposits on Mars. The hematite deposit on Mars may be a likely site to search for past life on Mars and should be considered for a sample return mission.

We investigated the soft body fossil of a tadpole and a possible coprolite from the Oligocene Enspel Fossillagerstatte, Germany. A multi-disciplinary approach was designed using Scanning Electron Microscopy (SEM) combined with Energy Dispersive X-ray analysis (EDX), High Resolution Transmission Electron Microscopy (HRTEM), X-ray induced Photoelectron Spectroscopy (XPS), and Time of Flight-Secondary Ion Mass Spectrometry (ToF-SIMS). ToF-SIMS and XPS analysed samples remain undamaged so that samples can subsequently be SEM imaged. Preliminary SEM investigation on both samples revealed the presence of numerous sub-micron sized spherical structures having the characteristics of coccoid bacteria, such as cell division and extracellular polymeric substances (EPS). These structures could clearly be shown to be mineralised, as demonstrated by the EDX analyses and HRTEM observations. We therefore interpret them as lithified bacterial biofilms (Westall et al., 2000). ToF-SIMS analyses revealed a variety of organic molecules in the atomic mass unit (AMU) range from 0 to 1000 AMU. Preliminary identifications include polycyclic aromatic hydrocarbons (PAH) (Stefan et al., 1999) and possibly cyclic triterpenoids (hopanoids). Further work on peak identification is currently underway. SEM analysis of the possible coprolite analysed by ToF SIMS showed that the material consists purely of fossil bacterial cells and polymeric substances. This is thus the first successful effort to combine spectral data with morphological information. The advantages of non-destructive in-situ analysis for biomarker detection are invaluable, particularly with respect to Mars sample return missions, as it may allow us to identify remains of former microbial life on terrestrial and extraterrestrial materials.

The precise nature of their shield materials is unknown, although their general morphology as observed using Viking Orbiter (VO) images is consistent with pyroclastic deposits. Their eruptive histories may include a transition from dominantly explosive to effusive activity possibly related to climate changes on Mars. High-resolution MOC images and detailed topography collected using MOLA are being used to improve our understanding of these volcanoes. Previous analyses using Earth-based radar indicated that Tyrrhena Patera flank slopes range from 0.2 to 3.0 degrees , and that the structure was approximately 1.5 km tall. Analyses using MOLA data reveal that the highest point on the Tyrrhena Patera summit is 1830 m above the surrounding plains, and that flank slopes range from <0.5 degrees to almost 2.0 degrees . The volcano is asymmetric, with the steepest slopes on the eastern flank and shallower slopes to the west. Near-summit slopes of Tyrrhena Patera are higher (by approximately 1.0 degrees ) than those lower on the flanks. Steeper slopes correspond to previously mapped "upper shield materials"; slope breaks correlate with erosional scarps observed on VO images. USGS topography of Hadriaca Patera yielded flank slopes of <1.0 degrees . MOLA reveals that Hadriaca Patera is 1350 m tall, and that its flanks are also asymmetric, with slopes ranging from 0.07 degrees to the west to 0.44 degrees on the east. These low slopes are consistent with shield materials of Hadriaca and Tyrrhena Paterae being composed of pyroclastic deposits. MOC images of the flanks of both volcanoes reveal an abundance of dunes, and no apparent primary lava flow forms. Although observations made using MOC and MOLA are consistent with previous interpretations of Hadriaca and Tyrrhena Paterae, topographic data indicate a complex evolution of their summit calderas, and multiple stages of volcano degradation. Additional analyses are needed to fully understand the construction and erosion of these volcanoes.

This work is an extension of previous studies that showed approximately 25% of magnetite particles extracted from the ALH84001 carbonate globules have a prismatic/hexaoctahedral morphology. These particles are slightly elongated crystals with approximately hexagonal or cubic image projections suggesting the underlying 3-D crystal geometry to be represented by hexagonal prisms or cubes. Faceted ends are present on each end and are rotationally offset from the facets at the other end by p/3 radians. Our transmission electron microscope analyses showed that the hexaoctahedral ALH84001 magnetite crystals are virtually indistinguishable from biogenic magnetites produced by terrestrial magnetotactic bacteria (e.g., strain MV-1): 1. Particles in both groups cluster in the superparamagnetic to single domain region. 2. Particles in both groups are chemically pure. 3. Particles in both groups are relatively defect free. 4. Particles in both groups are characterized by hexaoctahedral morphology. 5. Particles in both groups are elongated along the [111] axis MV-1 magnetite crystals are useful biomarkers because they are extraordinarily difficult, perhaps impossible, to produce by inorganic processes. Thus, we conclude that, by all available evidence, the ALH84001 hexaoctahedral magnetites are biogenic in origin. Would the environment on early Mars have favored the survival of magnetotactic bacteria? All life as we know it requires liquid water, along with energy and carbon sources. Early Mars could meet all the requirements of magnetotactic bacteria. Oceans or lakes and some oxygen were likely present over some period of time, as were energy and carbon sources. ALH84001 hexaoctahedral magnetites are indistinguishable from MV-1 magnetites in five characteristics; these characteristics can be considered a signature of biogenic origin, making ALH84001 hexaoctahedral magnetites the oldest known trace of life in the Solar System including Earth.

Tyrrhena has a large (200 by 1000 km), relatively young (late Amazonian to early Hesperian epochs) lava flow field containing well defined flow lobes and channels SW of the central caldera that is thought to reflect a late-stage transition from pyroclastic to effusive eruptive styles. Mars Global Surveyor topography allows us to significantly improves estimates of regional slope and flow dimensions. Our analysis of flow field emplacement parameters focuses on two flow lobe type examples. One has well defined flow lobe margins and flat tops in Viking Orbiter (VO) images. The second flow type, "centrally ridged" flows, is often visible in VO images as a discontinuous channel with no clear flow margins. The flat-topped flows have been suggested to be surface sheet-like and open channel-fed flows; and the centrally ridged flows lava tubes or channels. Our initial study site (near 257.2W, 26.4S) includes a flat-topped channelized flow and a centrally ridged flow with a discontinuous channel and no apparent flow margins. Using gridded MOLA topography, it is apparent that the flat-topped flow (40-80 m thick) has additional subtle topographic lateral extent and a central channel-like depression near the terminus. The centrally ridged flow (20-50 m thick) has topographic margins and relief , and is as wide as, and sometimes as tall as the flat-topped flow. The regional slope is 0.3 degrees, with local downflow slopes of 0.05-0.5 degrees. We calculate channel flow rates for an assumed viscosity range of 500-10000 Pa s, and find flow rates of 100-5000 m (super 3) /s for both the flat-topped flow's shallow channel (10 m deep, 1.2 km across), and the centrally ridged flow's deeper narrower channel (20 m deep, 300-600 m across). These rates are roughly ten times smaller than we have found for lava flows in the Syrtis and Elysium regions.

For the portion of Mars we previously studied in detail (the 180 degrees of longitude centered on 0W between + or -75 degrees latitude) QCDs larger than 200 km in diameter outnumber visible impact basins of the same size by a factor of 3. Most of the MOLA-found basins are in the ancient cratered terrain. The few previously mapped in the lowland plains are significantly shallower than those in the highlands, perhaps consistent with a greater depth of burial. Since our original study the resolution of the MOLA data has increased by a factor 4, making possible the identification of more subtle and smaller QCDs. We have conducted a detailed search for QCDs larger than 50 km diameter in the northern lowlands and compared their number and their distribution with visible impact craters and basins. At latitudes above 55N, visible impacts follow a -2 log-log cumulative number versus diameter distribution. QCDs larger than 100 km in diameter parallel this curve but are 3-4 times more numerous, consistent with our earlier results in cratered terrain. Extension to lower latitudes adds numerous visible and "almost" visible as well as MOLA-found basins in the knobby terrain of eastern Elysium and western Amazonis. The large number found here at modest low elevations (compared with a smaller number at lower elevations) may indicate less efficient burial in this region.

Ten students were divided into five teams, each of which formulated an original, independent research project within the Cerberus Plains of Mars (2-21N, 176-190E) using the latest MOLA topography and available Mars Global Surveyor (MGS) and Viking images. Taken collectively, the intent of the projects was to assess the potential suitability of this region as a future landing site. The goal of this paper is to explain the Mars 2000 project organization and activities in order to assist development of projects similar in design and scope. The Mars 2000 Project was organized into three primary phases. In the first, several days of intensive lecture introduced students to remote sensing techniques, the geology of Mars, current landing site selection constraints, and the initiation of life on Earth. Students also learned how to work with MGS and Viking data. Faculty and students then worked together over a 4-day period to select the study area, define the student teams, and formulate each team's research project. This phase concluded with a formal proposal from each team defining their research objective, approach, and the potential significance of their expected results. In the second phase, lasting three weeks, each team worked through their data collection and quantitative analysis. Topics included assessment of (a) Orcus Patera's origin, (b) Marte Valles' fluvial channel flow, (c) Marte Valles' lava channel flow, (d) regional wrinkle ridge formation, and (e) regional stratigraphy and unit ages. The final phase was used to complete the teams' research papers, give short summary talks, and construct posters to present at the 14th Keck Research Symposium in Geology and the 32nd Lunar and Planetary Science Conference in the spring of 2001.

To understand the compositional, mineralogical, and process implications of these data, we obtained major element, mineralogical, and magnetic data for well-crystalline and nanophase ferric minerals, terrestrial analogue samples with known geologic context, and SNC meteorites. Analogue samples include unaltered, palagonitic, and sulfatetic tephra from Mauna Kea Volcano (hydrolytic and acid-sulfate alteration), steam vent material from Kilauea Volcano (hydrolytic alteration), and impactites from Meteor Crater (relithification). Salient results for Mars Pathfinder include: (1) Band depths BD530b and BD600 and the reflectivity ratio R800/R750 are consistent with the dominant ferric mineral being nanophase ferric oxide associated with an unknown amount of H (sub 2) O and occurring in composite particles along with subordinate amounts of other ferric minerals. Hematite and hematite plus nanophase goethite are most consistent with the data, but maghemite, akaganeite, schwertmannite, and nanophase lepidocrocite are also possible interpretations. Ferric oxides that are consistently not favored by the data as sole alteration products are jarosites and well-crystalline goethite and lepidocrocite. (2) The strength of the ferric adsorption edge (R750/R445) implies the Fe (super 3+) /Fe (super 2+) values for Pathfinder rock and soil are within the ranges 0.7-3 and 3-20, respectively. (3) Ferrous silicates are indicated for subsets of Pathfinder rocks and soils. One subset has a band minimum near 930 nm that can attributed to low-Ca pyroxene. Alternatively, the band could be a second manifestation of certain ferric oxides, including nanophase goethite, maghemite, akaganeite, and schwertmannite. Another subset has a negative spectral slope from approximately 800 to 1005 nm which could result from the high-energy wing of a high-Ca pyroxene and/or olivine band, a mixture of bright and dark materials, and, for rocks, thin coatings of bright dust on dark rocks. (4) Chemical data on Pathfinder rocks and soils are consistent with two-component mixtures between an "andesitic" rock with low MgO and SO (sub 3) concentrations (soil-free rock) and a global, basaltic soil with high MgO and SO (sub 3) concentrations (rock-free soil). Pathfinder rock-free soil can be modeled as a chemical mixture of SNC meteorites and the Pathfinder soil-free rock. (5) Pathfinder soil cannot be obtained by chemical alteration of Pathfinder rocks by any of the hydrolytic and acid-sulfate alteration processes we studied. Presumably, global mixing has obscured and possibly erased the elemental signatures of chemical alteration. (6) The strongly magnetic phase in palagonitic and sulfatetic tephra is titanomagnetite and possibly its oxidation product titanomaghemite (Fe-Ti spinels). The saturation magnetization of the tephra samples (0.5-2.0 Am (super 2) /kg) is at or below the low end of the range inferred for Martian dust (4+ or -2 Am (super 2) /kg), implying that lithogenic Fe-Ti spinels are a possible candidate for the Martian strongly magnetic phase. (7) The predominantly palagonitic spectral signature and magnetic nature of Martian soil and dust are consistent with glassy precursors with imbedded Fe-Ti spinel particles. Comparison with lunar glass production rates suggests that production of sufficient quantities of glassy materials on Mars by volcanic and impact processes is sufficient to account for these observations.

We describe initial results from these measurements, concentrating on multispectral and elemental data, and use these data, along with previous Viking, SNC meteorite, and telescopic results, to help constrain the origin and evolution of Martian soil and dust. We find that soils and dust can be divided into at least eight distinct spectral units, based on parameterization of Imager for Mars Pathfinder (IMP) 400 to 1000 nm multispectral images. The most distinctive spectral parameters for soils and dust are the reflectivity in the red, the red/blue reflectivity ratio, the near-IR spectral slope, and the strength of the 800 to 1000 nm absorption feature. Most of the Pathfinder spectra are consistent with the presence of poorly crystalline or nanophase ferric oxide(s), sometimes mixed with small but varying degrees of well-crystalline ferric and ferrous phases. Darker soil units appear to be coarser-grained, compacted, and/or mixed with a larger amount of dark ferrous materials relative to bright soils. Nanophase goethite, akaganeite, schwertmannite, and maghemite are leading candidates for the origin of the absorption centered near 900 nm in IMP spectra. The ferrous component in the soil cannot be well-constrained based on IMP data. Alpha proton X-ray spectrometer (APXS) measurements of six soil units show little variability within the landing site and show remarkable overall similarity to the average Viking-derived soil elemental composition. Differences exist between Viking and Pathfinder soils, however, including significantly higher S and Cl abundances and lower Si abundances in Viking soils and the lack of a correlation between Ti and Fe in Pathfinder soils. No significant linear correlations were observed between IMP spectral properties and APXS elemental chemistry. Attempts at constraining the mineralogy of soils and dust using normative calculations involving mixtures of smectites and silicate and oxide minerals did not yield physically acceptable solutions. We attempted to use the Pathfinder results to constrain a number of putative soil and dust formation scenarios, including palagonitization and acid-fog weathering. While the Pathfinder soils cannot be chemically linked to the Pathfinder rocks by palagonitization, this study and McSween et ai. [1999] suggest that palagonitic alteration of a Martian basaltic rock, plus mixture with a minor component of locally derived andesitic rock fragments, could be consistent with the observed soil APXS and IMP properties.

The MAE measurements indicate steady dust accumulation at a rate of about 0.28% per day.

A major correction introduces a scaling of Srokosz's model by nonnegligible dimensionless ratios that depend on the slope variance of both long and short waves. With these modifications the EM bias is no longer simply a function of the cross skewness between surface elevation and slope but now depends on the variance ratios that represent the modulation between short and long waves. Inclusion of these ratios can reduce previous EM bias estimates by as much as 50%. Different directions for the longwave and shortwave field are also accounted for in the two-dimensional development of our approach. A radar frequency dependence consistent with observation is also predicted by the new model. Derivation extending our development to the next higher order in wave statistics is also presented and discussed. Copyright 2000 by the American Geophysical Union.

Consequently, shifts in the earth's radiative balance are expected with accompanying alterations to the earth's climate. With these anticipated, and perhaps already observable, changes in both global and regional climate, managers of regional water resources seek insight to the possible impacts climate change may have on their present and future water supplies. The types and degrees of impacts that climate change may have on New York City's water supply system were assessed in a study of a watershed as Allaben, New York. Hypothetical scenarios of future climate and climate change projections from three General Circulation Models (GCMs) were used in conjunction with the WatBal hydrological model and the Palmer Drought Severity Index (PDSI) to ascertain how runoff and soil moisture from this watershed may change in a warmer climate. For the worst case predictions, the results indicate than within the century of the 2000s, the watershed's air temperature may increase up to about 11 degree F, while its precipitation and runoff may decrease by about 13 and 30 percent, respectively. If this watershed is typical of the others within the New York City water supply system, the system's managers should consider implementing mitigation and adaptation strategies in preparation for the worst of these possible future conditions.

Interactive museum exhibits, developed in an innovative partnership between TOPEX/Poseidon Science Working Team members, museums and the TOPEX/Poseidon outreach office have proved to be highly successful. Travelling versions of the exhibits are available to informal education institutions and one set of exhibits is currently touring shopping centers, themselves an innovative venue. The `Visit to an Ocean Planet` CD-ROM, released earlier this year, is designed for middle school science students and can be used at many levels including the university undergraduate level. The CD-ROM is divided into three sections. The `Mission' section concentrates on the basics of orbits, measurement systems and satellites including the TOPEX/Poseidon. The `Guide' section contains teaching materials including classroom activities, background materials, images and animations. The `Expeditions' section contains a section on the 1997 El Nino, oceanography careers, and ocean science cruise planning. The CD-ROM is particularly innovative in its approach to learning by discovery methods encompassing both classroom activities and individual activities. One such activity is the scientific cruise planning in which data and electronic handbooks are provided to engage students in the types of decisions made by research scientists. The TOPEX/Poseidon altimeter project is looking to develop innovative ways of making oceans information available to educators and the general public across the country. Towards this end the TOPEX/Poseidon project is in the process or recruiting a number of volunteers who will present Earth Science materials to educators and/or the general public. NASA scientists will also be encouraged to participate in this program. This project, the Envoy project, will involve teaming with existing organizations to ensure the widest possible distribution of materials and information.

N1 - Last updated - 2016-12-21 ER - TY - JOUR T1 - An Observationally Based Conceptual Model of Warm Oceanic Convective Rain in the Tropics AN - 18363982; 5303431 AB - Distinctively different Z-R relations for initial convective and transition rain at the surface were found during the Tropical Ocean and Global Atmosphere Coupled Ocean-Atmosphere Response Experiment. Initial convective rain (of 20-30-min duration) is marked by nearly constant median volume diameter of D sub(o) approximately 2 mm and narrow drop size spectra, while R rises to >50 mm h super(-1). The constant form of the drop spectra independent of rain rate indicates an equilibrium distribution that accounts for the near linearity between Z and R. The form of the distribution differs from those previously reported, however. In contrast, the airborne raindrop measurements at 3 km in climatologically similar conditions show size spectra closely resembling the equilibrium collision-coalescence-breakup spectra of Hu and Srivastava and others at R > 20 mm h super(-1). The center of the plateau (of near-constant size) of these spectra repeatedly occurs at a drop size of 1 plus or minus 0.1 mm whose fall speed equals the updraft speed. This suggests a mechanism in which the updraft decreases the rate of fall of the drops relative to the surface, thus extending the residence time for collisions and reducing the depth of fall required for equilibrium to be reached. At the same time the updraft separates the large fast-falling drops from the smaller ones. The large ones fall within the convergent core of the convective cell to form the narrow equilibrium drop spectra observed at the surface, while the small ones rise into the divergent air above the updraft maximum and fall out elsewhere if they survive. Also, the updrafts in warm tropical convective clouds that produce R > 20 mm h super(-1) are commonly 4-5 m s super(-1), the speeds necessary to support the 0.5-1.5-mm-diameter range of drop sizes at which the collision rate is maximized. The warm convective clouds of the western tropical Pacific Ocean appear to be well tuned to this process. The implications for radar measurements of rainfall are also treated.

These channels measure broadband radiances in the shortwave (0.3-5.0 mu m), total (0.3->100 mu m), and water vapor window regions (8-12 mu m). Ground-based radiometric calibrations of the CERES flight models were conducted by TRW Inc.'s Space and Electronics Group of Redondo Beach, California. On-orbit calibration and vicarious validation studies have demonstrated radiometric stability, defined as long-term repeatability when measuring a constant source, at better than 0.2% for the first 18 months of science data collection. This level exceeds by 2.5 to 5 times the prelaunch radiometric performance goals that were set at the 0.5% level for terrestrial energy flows and 1.0% for solar energy flows by the CERES Science Team. The current effort describes the radiometric performance of the CERES Proto-Flight Model on the Tropical Rainfall Measuring Mission spacecraft over the first 19 months of scientific data collection.

Since then, much progress has been made in the calibration of the sensors, the improvement of the rainfall algorithms, and applications of these results to areas such as data assimilation and model initialization. The TRMM Microwave Imager (TMI) calibration has been corrected and verified to account for a small source of radiation leaking into the TMI receiver. The precipitation radar calibration has been adjusted upward slightly (by 0.6 dBZ) to match better the ground reference targets; the visible and infrared sensor calibration remains largely unchanged. Two versions of the TRMM rainfall algorithms are discussed. The at-launch (version 4) algorithms showed differences of 40% when averaged over the global Tropics over 30-day periods. The improvements to the rainfall algorithms that were undertaken after launch are presented, and intercomparisons of these products (version 5) show agreement improving to 24% for global tropical monthly averages. The ground-based radar rainfall product generation is discussed. Quality-control issues have delayed the routine production of these products until the summer of 2000, but comparisons of TRMM products with early versions of the ground validation products as well as with rain gauge network data suggest that uncertainties among the TRMM algorithms are of approximately the same magnitude as differences between TRMM products and ground-based rainfall estimates. The TRMM field experiment program is discussed to describe active areas of measurements and plans to use these data for further algorithm improvements. In addition to the many papers in this special issue, results coming from the analysis of TRMM products to study the diurnal cycle, the climatological description of the vertical profile of precipitation, storm types, and the distribution of shallow convection, as well as advances in data assimilation of moisture and model forecast improvements using TRMM data, are discussed in a companion TRMM special issue in the Journal of Climate.

One of the methods available is the surface reference technique in which the radar surface return in rain-free areas is used as a reference against which the path-integrated attenuation is obtained. Despite the simplicity of the basic concept, an assessment of the reliability of the technique is difficult because the statistical properties of the surface return depend not only on surface type (land/ocean) and incidence angle, but on the detailed nature of the surface scattering. In this paper, a formulation of the technique and a description of several surface reference datasets that are used in the operational algorithm are presented. Applications of the method to measurements from the PR suggest that it performs relatively well over the ocean in moderate to heavy rains. An indication of the reliability of the results can be gained by comparing the estimates derived from different reference datasets.

Rather than relying on some absolute "truth" to verify retrievals, this paper focuses on one assumption - namely, the drop size distribution (DSD) - and how different DSDs lead to improved or reduced consistency. Results from a case in the central Pacific suggest that a crude consistency may be achieved if a different drop size is used for the radiometer and the radar. In this particular case, a Marshall-Palmer or a gamma distribution with the shape parameters properly set leads to similar results. Although this study offers no independent validation of its conclusions, it does demonstrate that rainfall validation need not be confined to surface rainfall measurements, which are only loosely related to the volumetric observations made by most sensors. As mean size distributions of raindrops are measured in the TRMM field experiments by disdrometers, profilers, multiparameter radars, and direct aircraft observations, the technique presented in this paper can be applied on a storm-by-storm basis, and conclusions can be verified directly.

The AGPI is then merged with rain gauge information (mostly over land) to provide finescale (1 degree latitude x 1 degree longitude) pentad and monthly analyses, respectively. The TRMM merged estimates are 10% higher than those from the Global Precipitation Climatology Project (GPCP) when integrated over the tropical oceans (37 degree N-37 degree S) for 1998, with 20% differences noted in the most heavily raining areas. In the dry subtropics the TRMM values are smaller than the GPCP estimates. The TRMM merged product tropical-mean estimates for 1998 are 3.3 mm day super(-1) over ocean and 3.1 mm day super(-1) over land and ocean combined. Regional differences are noted between the western and eastern Pacific Ocean maxima when TRMM and GPCP are compared. In the eastern Pacific rain maximum the TRMM and GPCP mean values are nearly equal, which is very different from the other tropical rainy areas where TRMM merged product estimates are higher. This regional difference may indicate that TRMM is better at taking into account the vertical structure of the rain systems and the difference in structure between the western and eastern (shallower) Pacific convection. Comparisons of these TRMM merged analysis estimates with surface datasets shows varied results; the bias is near zero when compared with western Pacific Ocean atoll rain gauge data, but is significantly positive as compared with Kwajalein radar estimates (adjusted by rain gauges). Over land the TRMM estimates also show a significant positive bias. The inclusion of gauge information in the final merged product significantly reduces the bias over land, as expected. The monthly precipitation patterns produced by the TRMM merged data process clearly show the evolution of the El Nino-Southern Oscillation (ENSO) tropical precipitation pattern from early 1998 (El Nino) to early 1999 (La Nina) and beyond.

Metamorphism, partial melting and incomplete differentiation (i.e. incomplete separation of melt from residue) produced metallic, sulphide-rich and silicate partial melts as well as metamorphosed chondritic materials and residues. Catastrophic impact break-up and reassembly of the debris while near the peak T mixed materials from various depths into the re-accreted parent body. Thus, molten metal from depth was mixed with near-surface silicate rock, resulting in the formation of silicate-rich IAB irons and winonaites. Ages of silicate inclusions and winonaites of 4400-4540 m.y. Ga indicate this entire process occurred early in solar system history.

However, Mocs has very low (super 22) Ne/ (super 21) Ne ratios indicative of deep burial in a large meteoroid, but radionuclide levels at saturation values typical for much smaller meteoroids: this paradox suggests a possible complex history in which Mocs initially was buried deeply in a large object for 110 m.y. followed by exposure in a 65 cm object for 10.5 m.y. Relative shielding was inferred from the measured (super 22) Ne/ (super 21) Ne ratios assuming constant (super 22) Ne/ (super 21) Ne production for all samples during the first stage. These shielding levels, which are supported by estimates based on (super 36) Cl production by neutron capture, indicate a possible relationship between depth of samples in the Mocs meteoroid and fall location in the strewn field.

The chemical features of the spherules indicate that their precursor materials were characterized by extreme elemental fractionations under oxidizing conditions, which have not been observed in chondritic materials before. The liquidus T of the euhedral Fe,Ni-metal grains are lower than those of the coexisting ferrous silicates suggesting that the former crystallized in supercooled silicate melts. The metal grains are not decomposed into taenite and kamacite, suggesting fast postcrystallization cooling at T 400-500 K.

It is plausible that the Earth accreted water all along its formation, from the early phases when the solar nebula as still present to the late stages of gas-free sweep-up of scattered planetesimals. The net result of accretion from several reservoirs is that the water on Earth had essentially the D/H ratio typical of the water condensed in the outer asteroid belt. This is in agreement with the observation that the D/H ratio in the oceans is very close to the mean value of the D/H ratio of the water inclusions in carbonaceous chondrites.

Hence, it is intermediate between the Y74159-type polymict eucrites, which contain negligible amounts of magnesian orthopyroxene, and the howardites. The present study provides mineralogical and bulk compositional data for the meteorite breccia and for six clasts. These clasts include both volcanic/igneous rocks and a variety of impact-generated rocks. A broad range of degrees of post-crystallization metamorphism affected these materials before the final aggregation of the breccia.

This meteorite experienced minor alteration and a low degree of thermal metamorphism (petrologic type 3.1) and escaped post-accretional brecciation. The alteration resulted in the formation of several minerals, including fayalite, hedenbergite which typically occur as veins. Fayalite and hedenbergite in MAC 88107 formed during late-stage, low-T ( approximately 150-200 degrees C) aqueous alteration. The data for MAC 88107 extend the evidence for an early onset of aqueous activity on chondrite parent bodies and reinforce the conclusion that liquid water played an important role in the chemical and mineralogical evolution of the first chondritic planetesimals.

In this work the vertical air motion measured by an aircraft gust probe is used as a discriminator which is independent of the textural methods. A threshold draft magnitude of approximately 1 m s super(-1) separates the two rain types. Simultaneous airborne in situ observations of drop size distributions (DSD) made during the Tropical Ocean-Global Atmosphere Coupled Ocean-Atmosphere Response Experiment (TOGA COARE) were used to compute Z, R, and other integral parameters. The data were quality controlled to minimize misclassifications. The convective and stratiform rains, observed just below the melting level but adjusted to surface air density, are characterized by power law Z-R relations (Z = 129R super(1.38) (convective) and 224R super(1.28) (stratiform)). However, at R < 10 mm h super(-1), the convective population is essentially coincident with the small-drop size, small-Z portion of the stratiform population. Tokay and Short [1996] found a similar result when their algorithm did not separate the rain types unambiguously at R < 10 mm h super(-1). The physical reasons for the wide variability of the drop size spectra and Z-R points in stratiform rain and their overlap with that of convective rain are proposed. The subtle distinctions in the microphysical properties and the Z-R relations by rain type could not be found by Yuter and Houze (YH) using the same airborne DSD data set as that in this work and a radar-based textural classification algorithm.

The main interest is in the fact that the ball can follow a curved flight path that is not always under the control of the bowler. ne basic aerodynamic principles responsible for the nonlinear flight or 'swing' of a cricket ball were identified several years ago and many papers have been published on the subject. In the last 20 years or so, several experimental investigations have been conducted on cricket ball swing, which revealed the amount of attainable swing, and the parameters that affect it. A general overview of these findings is presented with emphasis on the concept of late swing and the effects of meteorological conditions on swing. In addition, the relatively new concept of 'reverse' swing, how it can be achieved in practice and the role in it of ball 'tampering', are discussed in detail. A discussion of the 'white' cricket ball used in last year's World Cup, which supposedly possesses different swing properties compared to a conventional red ball, is also presented.

Seven subjects completed a continuous supine protocol of 20 min of rest, 20 min of cycle exercise at 40 percent peak oxygen consumption, V-dot O2(peak), 20 min of cycle exercise at 65 percent V-dot O2(peak), and 20 min of recovery. T(es), T(re), and T(in) were recorded each min. Temperatures were not different after 20 min of rest, but T(es) and T(in) were greater than T(re) at the end of the 40 percent (T(es): 37.38 +/- 0.11; T(in): 37.35 +/- 0.06; T(re): 37.20 +/- 0.10 C) and 65 percent V-dot O2(peak) stages (T(es): 37.83 +/- 0.10; T(in): 37.75 +/- 0.05; T(re): 37.63 +/- 0.08 C). After 20 min of recovery, T(es) (37.24 +/- 0.011 C) was less than either T(re) or T(in), which were not different from each other (T(in): 37.39 +/- 0.09; T(re): 37.44 +/0.09 C). Time to threshold for increased temperature from rest (+0.10 C) for T(es) (10.0 +/- 1.1 min) was not different from T(in) (14.0 +/- 1.2 min) but less than T(re) (15.7 +/- 1.6 min). Time to reach peak temperature was less for T(es) (36.6 +/- 1.8 min) than T(in) (40.6 +/- 0.9 min) and T(re) (41.4 +/- 0.5 min). Similarly, time to a decrease in temperature (-0.10 C) after exercise was less for T(es) (3.7 +/- 0.4 min) than T(in) (7.1 +/- 1.5 min) and T(re) (10.6 +/- 1.9). Measurement of T(in) may be an alternative to T(es) to measure T(core) specific time points during exercise with an understanding of the slower response of T(in) compared with T(es).

We hypothesized that 40 min of supine exercise per day in a LBNP chamber at 1.0-1.2 body wt (58 +/- 2 mm Hg LBNP) maintains aerobic fitness and sprint speed during 15 days of 6 deg head-down bed rest (simulated microgravity). Seven male subjects underwent two such bed-rest studies in random order: one as a control study (no exercise) and one with daily supine LBNP treadmill exercise. After controlled bed-rest, time to exhaustion during an upright treadmill exercise test decreased 10 percent, peak oxygen consumption during the test decreased 14 percent, and sprint speed decreased 16 percent (all P less than 0.05). Supine LBNP exercise during bed rest maintained all the above variables at pre-bed-rest levels. Our findings support further evaluation of LBNP exercise as a countermeasure against long-term microgravity-induced deconditioning.

A digital elevation model of Hofsjoekull, which was constructed using SAR interferometry, was used to plot the SAR backscatter coefficient ( sigma degree ) vs elevation and air temperature along transects across the ice cap. Seasonal and daily sigma degree patterns are caused by freezing or thawing of the ice-cap surface, and abrupt changes in sigma degree are noted when the air temperature ranges from similar to -5 degree to 0 degree C. Late-summer 1997 sigma degree (SAR) and reflectance (Landsat) boundaries agree and appear to be coincident with the firn line and a SAR sigma degree boundary that can be seen in the January 1998 SAR image. In January 1994 through 1998, the elevation of this sigma degree boundary on the ice cap was quite stable, ranging from 1000 to 1300 m, while the equilibrium-line altitude, as measured on the ground, varied considerably. Thus the equilibrium line may be obscured by firn from previous years. Techniques are established to measure long-term changes in the elevation of the firn line and changes in the position of the ice margin.

Relaxing route and altitude restrictions would reduce the regularity of traffic through individual sectors, possibly impairing controller situation awareness. We examined the impact of this reduced regularity in four visual search experiments that tested controllers' detection of traffic conflicts in the four conditions created by factorial manipulation of fixed routes (present vs. absent) and altitude restrictions (present vs. absent). These four conditions were tested under varying levels of traffic load and conflict geometry (conflict time and conflict angle). Traffic load and conflict geometry showed strong and consistent effects in all experiments. Color coding altitude also substantially improved detection times. In contrast, removing altitude restrictions had only a small negative impact, and removing route restrictions had virtually no negative impact. In some cases conflict detection was actually better without fixed routes. The implications and limitations of these results for the feasibility of free flight are discussed. Actual or potential applications include providing guidance in the selection of free flight operational concepts.

A total of 280 samples was collected. The four samplers were operated simultaneously, each sampling 100 L of air with collection on trypticase soy agar. The data were corrected by applying positive hole conversion factors for the Burkard portable, Andersen two-stage, and SAS Super 90 air samplers, and were expressed as log sub(10) values prior to statistical analysis by analysis of variance. The Burkard portable air sampler retrieved the highest number of airborne culturable bacteria at four of the five sampling sites, followed by the SAS Super 90 and the Andersen two-stage impactor. The number of bacteria retrieved by the RCS Plus was significantly less than those retrieved by the other samplers. Among the predominant bacterial genera retrieved by all samplers were Staphylococcus, Bacillus, Corynebacterium, Micrococcus, and Streptococcus..

Research over the decades has substantially improved physical understanding of noise-generating mechanisms, and various design concepts have been investigated to control noise radiation using advanced blade planform shapes and active blade control techniques. The important parameters to control rotor blade-vortex interaction noise and vibration have been identified: blade tip vortex structures and its trajectory, blade aeroelastic deformation, and airloads. Several blade tip design concepts have been investigated for diffusing tip vortices and also for reducing noise. However, these tip shapes have not been able to substantially reduce blade-vortex interaction noise without degradation of rotor performance. Meanwhile, blade root control techniques, such as higher-harmonic pitch control (HHC) and individual blade control (IBC) concepts, have been extensively investigated for noise and vibration reduction. Recently, active blade control concepts with smart structures have been investigated with the emphasis on active blade twist and trailing edge flap. Smart structures technologies are very promising, but further advancements are needed to meet all the requirements of rotorcraft applications in frequency, force, and displacement.

Additionally, observations of the Leonids were recorded both digitally with the Liquid Mirror Telescope (LMT) and with a low light level camera at the JSC Observatory near Cloudcroft, New Mexico. The tapes were analyzed using a computer-automated meteor analysis system developed at JSC. These results were used to form estimates of the Leonid mass-distribution. These estimates were compared to a Leonid mass distribution model used by NASA in risk assessment calculations associated with Space Shuttle missions. The observed data agrees favorably with the NASA model in the 0.002 to 0.02 milligram range (based upon the LMT observations) and in the 0.02 to 0.2 gram range (based on the low light level camera observations). This comparison supports the continued use of this model.

This expression incorporates assumptions about cloud physics, such as the independence of the cloud liquid water content and the width of the droplet size distribution on droplet concentrations. Averaged over all 69 ship track penetrations, cloud liquid water content decreased slightly and the droplet size distributions broadened from the ambient values. For the 17 cases for which albedos were measured during overflights, Twomey's parameterization represents the trend of albedo changes with droplet concentrations remarkably well, passing through the midpoints of the considerable spread in the data. The fortuitous agreement results from compensating changes in cloud properties. Together with the albedo changes, the changes in cloud liquid water content and droplet size distributions imply that cloud thickness usually increased in the ship tracks. Such an increase was observed on the occasions that changes in cloud thickness were recorded (in the Sanko Peace ship track during very clean ambient conditions). Unfortunately systematic measurements of cloud thickness were not made for most of the ship tracks observed. The greatest outlier in the data corresponds to measurements made under horizontally inhomogeneous ambient conditions; possible explanations for its divergence include an increase in cloud thickness or an error in matching above-cloud albedo measurements with in-cloud microphysics measurements.

The sensitivity of visible and near-infrared wavelengths for detecting reflectance changes in ship tracks is discussed, including the use of a modified cloud susceptibility parameter, termed the "contrast susceptibility," for assessing the sensitivity of background cloud microphysics on potential track development. It is shown that the relative change in cloud reflectance for ship tracks is expected to be larger in the near-infrared than in the visible and that 3.7- mu m channels, widely known to be useful for detecting tracks, have the greatest sensitivity. The usefulness of contrast susceptibility as a predictor of ship track contrast is tested with airborne and satellite remote sensing retrievals of background cloud parameters and track contrast. Retrievals are made with the high spatial resolution Moderate Resolution Imaging Spectroradiometer Airborne Simulator flown on the National Aeronautics and Space Administration's high-altitude ER-2 aircraft, and with the larger-scale perspective of the advanced very high resolution radiometer. Observed modifications in cloud droplet effective radius, optical thickness, liquid water path, contrast susceptibility, and reflectance contrast are presented for several ship tracks formed in background clouds with both small and large droplet sizes. The remote sensing results are augmented with in situ measurements of cloud microphysics that provide data at the smaller spatial scales.

The rainwater samples were collected during an Intergovernmental Oceanographic Commission (IOC) sponsored baseline expedition in May and June 1996. The concentration of hydrogen peroxide was determined on diluted samples using a cobalt-catalyzed luminol chemiluminesence method. The concentration of hydrogen peroxide in rainwater varied from 3.5 to 71 mu M with an average (n = 25) and standard deviation of 26 and 22 mu M, respectively. These are similar to previously reported average hydrogen peroxide concentrations in marine rainwater of the Gulf of Mexico (40 mu M), the western Atlantic Ocean (13 mu M), and Florida Keys (28 mu M). The concentration of hydrogen peroxide in rainwater varied with time of the day, with lower concentrations in early morning and higher concentrations in the late afternoon. The rainwater concentration of hydrogen peroxide also decreased during a rainstorm that may be an indication of a washout effect. The general levels of hydrogen peroxide in rainwater reported here and elsewhere together with the satellite-measured global distribution of precipitation indicate that wet deposition could affect water column hydrogen peroxide significantly in certain parts of the world.

Two-layered models have also been proposed in which the particle consists of a dry snow or ice core surrounded by water or a wet snow mixture. For both types of particle models, the mixtures are characterized by effective dielectric constants. This information, along with particle shape, size, and orientation, provides the necessary data for calculating the scattering characteristics of the particles. The most commonly used formulas for the effective dielectric constant, epsilon sub(eff), are those of Maxwell Garnett and Bruggeman. To understand the applicability and limitations of these formulas, an expression for epsilon sub(eff) is derived that depends on the mean internal electric fields within each component of the mixture. Using a conjugate gradient numerical method, the calculations are carried out for ice-water mixtures. Parameterization of the results in terms of the fractional water volume and the electromagnetic wavelength provides an expression for epsilon sub(eff) for wavelengths between 3 and 28 mm. To circumvent the laborious task of parameterizing epsilon sub(eff) with wavelength for air-ice-water mixtures, several approximate formulations are proposed. Tests of the accuracy of the formulas are made by calculating the mean and variance from different particle realizations and by comparison to a previous method. Tests of the applicability of the formulas for epsilon sub(eff) are made by changing the shape, size, and orientations of the inclusions. While the formulas are adequate over a certain range of inclusion sizes and for a change in shape from cubic to spherical, they are not applicable to highly eccentric, aligned inclusions such as rods or plates.

The unsupervised classification method is based on our observation that the frequency distributions of Coastal Zone Color Scanner (CZCS) annual pigment means and standard deviations are nonuniform and contain distinct clusters. The frequency distributions are used to objectively determine ocean areas with similar pigment statistical characteristics. A major separation between high variance, high pigment and lower variance, lower pigment waters is observed in terms of global ocean area. The ocean areas determined with our method reflect different biological responses to variations in ocean physical dynamics. Pigment means and variances around the Joint Global Ocean Flux Study (JGOFS) Time Series stations are used as fiducial characteristics. Hawaii Ocean Time-series (HOT) station is associated with the low-variance portion of the global annual pigment distribution characteristic of the central gyres, but shows slightly higher mean and variance than the minima in the central Pacific gyre. The Bermuda Atlantic Time Series (BATS) pigment associations comprise a transitional region between the gyres and high-variance pigment areas, and circumscribe the HOT pigment associations. Together, these associations encompass 23% (HOT-like) and 48% (BATS-like) of the Northern Hemisphere open ocean. The Pacific regions delineated by the JGOFS station pigment-based patterns are similar to distributions described historically for Pacific zooplankton communities. Interannual variation for the northern hemisphere gyre area is on the order of by 10% for the 11/78-10/81 period.

In parallel with these efforts, much work has been devoted to the problem of attaching error estimates to these products. There are two main sources of error, the intrinsic errors in the remote sensing measurements themselves (retrieval errors) and the lack of continuity in the coverage by low earth-orbiting satellites (sampling error). Perhaps a dozen or so studies have attempted to estimate the sampling-error component. These studies have been based on rain gauge and radar-derived data, and the estimates vary so much that it is clear that the sampling error cannot be represented satisfactorily by a single value. These studies are reviewed. Some of the results reported in these studies are based on a method referred to in this paper as "resampling by shifts." The authors find that the method unfortunately tends to produce estimates that are subject to too much uncertainty to be used quantitatively. After setting these results aside, the authors find that the variability in the remaining sampling-error estimates can be explained to a considerable extent using assumptions common to many statistical models of rain. All such models predict that sampling error relative to the average rain rate R is proportional to R super(--1/2). Although the sampling error at any given site seems (to the extent that data have been examined) to change with R in the way predicted by the model, the proportionality constant in this relationship seen in the various studies appears to change from site to site. This constant can be obtained from the satellite estimates themselves if retrieval errors are not correlated over scales of the order of the grid-box size.

The results are statistically adjusted to have the same probability distribution as a rain gauge dataset. The climatologies take the form of the mean estimated rainfall for a 10-yr+ period, with subdivisions by month and meterological season. For the 6-yr period 1992-97, when two satellites were in operation, diurnal variability (to the extent it is discerned by four unequally spaced observations) is presented. In the mean, dramatic patterns of alternating morning and evening maxima are seen stretching from the northeast (Atlantic coast) across the continent to the Pacific. The effects of local circulations caused by topography, coastlines, and geography (river valleys) on the rainfall patterns are evident, particularly in the region around Manaus, Brazil, where the Negro and Solimoes Rivers merge. The interannual variability of the 10-yr rainfall estimate is examined by computing the deviations of yearly and warm-season (December-February) rainfall from their respective long-term means. Rainfall anomalies associated with El Nino and La Nina events then become apparent. This guage-adjusted satellite climatology enhances existing (gauge based) climatologies by increasing the spatial resolution and providing a common, spaceborne platform for assessing interannual variability. It maintains the same first- and second-order statistics as does the guage dataset, and allows a first attempt at examining the diurnal cycles by utilizing passive microwave observations (up to) four times per day.

These elevated plumes cause a relative maximum at about 5-7 km altitude in the vertical distribution of primary and secondary species characteristic of fuel combustion and biomass burning (CO, C sub(2)H sub(2), C sub(2)H sub(6), CH sub(3)Cl, PAN, O sub(3)). Similar plumes were also observed at mid-latitudes in the middle troposphere during three flights east of New Zealand (40-45 degree S). In all, pollution plumes with CO larger than 100 ppb were observed 24 times on seven separate flight days south of the equator. The observed plumes were frequently embedded in very dry air. Ten-day back trajectory analysis supports the view that these originated from the biomass burning regions of South Africa (and South America) and were transported to the South Pacific along long-distance subsiding trajectories. The chemical composition of the southern Pacific troposphere analyzed from the PEM-Tropics-A data is compared with data from the tropical regions of the northern Pacific (PEM-West-A) and southern Atlantic (TRACE-A) during the same Sept/Oct time period. Sizable perturbations in the abundance of ozone and its key precursors, resulting from the transport of pollution originating from biomass burning sources, are observed in much of the Southern Hemispheric troposphere.

The procedure employs a strategy called parameter-based partitioning of the design space and uses a sequence of response surfaces based on both neural networks and polynomial fits to traverse the design space in search of the optimal solution. This approach results in response surfaces that have both the power of neural networks and the economy of low-order polynomials (in terms of number of simulations needed and network training requirements). Such an approach can handle design problems with many more parameters than would be possible using neural networks alone. The design procedure has been applied to the redesign of a turbine airfoil from a modern jet engine. This redesign involved the use of 15 design variables. The results obtained are closer to the target design than those obtained using an earlier method with only three design variables. The capability of the method in transforming generic shapes, such as simple curved plates, into optimal airfoils is also demonstrated.
