Description

Our approach to high-pressure carbon dioxide storage will directly address the challenges associated with storage of compressed carbon dioxide - the need to reduce power consumption, mass and volume while limiting acoustic impact. Successful implementation will reduce gas compressor power by over 50 % and required maximum tank pressure by over 80 % while maintaining storage tank footprint and total standard volume of gas. This is accomplished through the use of our high gas capacity physisorptive support architecture employing tailored zeolite sorbents. Added benefits include facile regenerability, equal applicability to other gases including oxygen and nitrogen, improved thermal management to control heats of desorption and adiabatic cooling during filling and empyting cycles. In addition to the energy savings, we expect that more compact, efficient, and less intrusive compression devices can be utilized. This approach is based on a novel regenerable high capacity physisorptive media storage system that will adsorb CO2 from a compressor system and store it at a relatively lowered pressure. On demand, the CO2 can be desorbed at a constant rate and released. For example, we can store an equivalent volumetric amount of CO2 at about 500 psi, compared to the current 3600 psi. There is a potential for substantial weight savings as well – while we add the mass of sorbent and support, mass reductions from use of thinner wall tanks and smaller compressors are likely to be larger, specific savings will be addressed as part of the proposed task plan. At the end of Phase I we will have demonstrated our approach in our in-house bench scale equipment, bringing the technology to TRL 3 with detailed performance information needed to go to TRL 4 in Phase II, including the delivery of suitable equipment to a NASA facility.

Description

The Floodplain Mapping/Redelineation study deliverables depict and quantify the flood risks for the study area. The primary risk classifications used are the 1-percent-annual-chance flood event, the 0.2-percent-annual- chance flood event, and areas of minimal flood risk. The Floodplain Mapping/Redelineation flood risk boundaries are derived from the engineering information Flood Insurance Studies (FISs), previously published Flood Insurance Rate Maps (FIRMs), flood hazard analyses performed in support of the FISs and FIRMs, and new mapping data, where available. The FISs and FIRMs are published by the Federal Emergency Management Agency (FEMA).

Description

This data set provides three data files in text format (.txt). One file contains a long time series of monthly biomass measurements and net primary productivity (NPP) estimates made between July 1984 and November 1994 on an ungrazed tropical dry savanna grassland in the Nairobi National Park, Kenya. The second file contains a shorter time series (October 1989-June 1991) of monthly biomass measurements made on an adjacent savanna that had been clipped in September 1989. The third file contains monthly and annual climate data for the study site for the period 1969-1989.Measurements of above-ground live phytomass, standing dead, and litter biomass were made on the 15th day of each month on the ungrazed grassland over the time series (except during 1987 and at a few other times). The time series for below-ground biomass (BNPP) measurements (live and dead) is more discontinuous with large gaps in 1987-1989. NPP estimates are only available for part of 1984 through 1986 on the ungrazed savanna. The above-ground NPP (ANPP) values averaged 1,004 g/m2/yr and BNPP averaged 875 g/m2/yr. The record of above- and below-ground biomass measurements for the clipped savanna is complete except for a few months in 1990. Revision Notes: Only the documentation for this data set has been modified. The data files have been checked for accuracy and are identical to those originally published.

Description

This data set contains annual county-level estimates of total atrazine use on 16 agricultural crops and four agricultural land uses between 1992 and 2007. For each year, atrazine use was estimated for all counties in the conterminous U.S. (except California) by combining (1) proprietary data from the DMRKynetec (DMRK) AgroTrak database on the mass of atrazine applied annually to agricultural crops, (2) county harvested crop acreage, from the 1992, 1997, 2002, and 2007 U.S. Department of Agriculture (USDA) Censuses of Agriculture, and (3) annual harvested crop acreage from the National Agriculture Statistics Service (NASS) for non-Census years between 1992 and 2007. Annual DMRK estimates of pesticide use on individual crops were derived from surveys of major field crops and selected specialty crops in multicounty areas referred to as Crop Reporting Districts (CRD). The CRD-level atrazine-use estimates were disaggregated to obtain county-level application rates by dividing the mass (pounds) of pesticides applied to a crop by the acreage of that crop in the CRD, to yield a rate per harvested acre. When atrazine-use estimates were not available for a CRD, crop, or year, an estimated CRD-level rate was developed following a hierarchy of decision rules that checked first for the availability of a crop application rate from surveyed atrazine application rate(s) for adjacent CRDs for a specific year, and second, the rates from surveyed CRDs within for USDA Farm Production Regions for a specific year or multiple years. The estimation method applied linear interpolation to estimate crop acreage for years when harvested acres for a crop and county were not reported in either the Census of Agriculture or the NASS database, but were reported by these data sources for other years for that crop and county. Data on atrazine use for the counties in California were obtained from farmers' reports of pesticide use collected and published by the California Department of Pesticide Regulation-Pesticide Use Reporting (DPR-PUR) because these data are more complete than DMRK survey data. National and state annual atrazine-use totals derived by this method were compared with other published pesticide-use estimates and were highly correlated. The method developed is designed to be applicable to other pesticides for which there are similar data; however, for some pesticides that are applied to specialty crops, fewer surveys are usually available to estimate application rates and there are a greater number of years with unreported crop acreage, potentially resulting in greater uncertainty in use estimates.

Description

This image represents a 1 meter resolution backscatter mosaic of the south shore of St. John, US Virgin Islands. NOAA's NOS/NCCOS/CCMA Biogeography Team and NOAA/NOS/OCS/HSD personnel, in collaboration with NOAA vessel Nancy Foster and territory, federal, and private sector partners, acquired multibeam bathymetry data in the US Virgin Islands from 2/18/04 to 3/5/04. Data was acquired with a pole-mounted Reson 8101 ER multibeam echosounder (240 kHz) and processed by a NOAA contractor using CARIS HIPS v5.4 software. Data has all correctors applied (attitude, sound velocity) and has been reduced to mean lower low water (MLLW) using final approved tides from NOAA COOPS. Data is in UTM zone 20 north, datum WGS84. Within CARIS, each line of backscatter data was evaluated for bottom tracking and was slant-range corrected. Data was not corrected for gain or transmit power artifacts. Backscatter mosaics were then created using the CARIS shine-through option. Finally, a georeferenced imagery file was exported from the mosaic. While the project was conducted to meet IHO Order 2 accuracy standards, there is a roll artifact (averaging 0.5m high) in the dataset that the user should take into consideration when performing any analysis.

Description

Scandate cathodes are proposed as a way to boost performance and life for electric space propulsion systems. This company has recently demonstrated breakthrough performance on these cathodes in other formats. We have demonstrated emission of 5 Amps/cm2 at 850 degrees CB, which is 200 degrees C below that of conventional cathodes. At this temperature they should live at least 100,000 hours. This makes scandate cathodes a candidate for use in deep space missions. In Phase I we propose construction and testing of several hollow scandate cathodes. We propose to do both vacuum and ion environment characterization on them. In Phase II we will begin active collaboration with NASA to test these cathodes in complete ion thrusters.

Coastal study data as defined in FEMA Gudelines and Specifications, Appendix D: Guidance for Coastal Flooding Analyses and Mapping, submitted as a result of a coastal study. Appendix D notes that a variety of analytical methodologies may be used to establish Base (1-percent-annual-chance) Flood Elevations (BFEs) and floodplains throughout coastal areas of the United States. Appendix D itemizes references for the methodologies currently in use by FEMA for specific coastal flood hazards, provides general guidance for documentation of a coastal flood hazard analysis, specifies flood hazard analysis procedures for the Great Lakes coasts, and outlines intermediate data submissions for coastal flood hazard analyses with new storm surge modeling and revised stillwater flood level (SWFL).

Description

In 1981, the Malheur National Wildlife Refuge NWR staff distributed a questionnaire to the National Wildlife Refuges in the lower 48 states to determine the scope of the carp problem in the National Wildlife Refuge System. Of 162 refuges surveyed, only 54 32 percent indicated no carp problems. Nearly half of the stations which reported no problem were either upland or coastal refuges without freshwater impoundments, while more than 80 percent of refuges with impoundments reported carp to be a management problem. Several methods have been employed by refuges to harvest and control carp with mixed success, but little has been reported in the literature on the effectiveness of these efforts. This paper describes longtenn efforts toward carp control at Malheur NWR and the response of waterfowl to those efforts.
