Description

The Digital Flood Insurance Rate Map (DFIRM) Database depicts flood risk information and supporting data used to develop the risk data. 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 DFIRM Database is derived from 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). The file is georeferenced to earth's surface using the State Plane projection and coordinate system. The specifications for the horizontal control of DFIRM data files are consistent with those required for mapping at a scale of 1:12000.

Description

NOAA's National Geophysical Data Center (NGDC) is building high-resolution digital elevation models (DEMs) for select U.S. coastal regions. These integrated bathymetric-topographic DEMs are used to support tsunami forecasting and modeling efforts at the NOAA Center for Tsunami Research, Pacific Marine Environmental Laboratory (PMEL). The DEMs are part of the tsunami forecast system SIFT (Short-term Inundation Forecasting for Tsunamis) currently being developed by PMEL for the NOAA Tsunami Warning Centers, and are used in the MOST (Method of Splitting Tsunami) model developed by PMEL to simulate tsunami generation, propagation, and inundation. Bathymetric, topographic, and shoreline data used in DEM compilation are obtained from various sources, including NGDC, the U.S. National Ocean Service (NOS), the U.S. Geological Survey (USGS), the U.S. Army Corps of Engineers (USACE), the Federal Emergency Management Agency (FEMA), and other federal, state, and local government agencies, academic institutions, and private companies. DEMs are referenced to the vertical tidal datum of Mean High Water (MHW) and horizontal datum of World Geodetic System 1984 (WGS 84). Grid spacings for the DEMs range from 1/3 arc-second (~10 meters) to 3 arc-seconds (~90 meters).

Description

NASA plans to produce cryogenic oxygen and hydrogen to power regenerative fuel cells for lunar surface exploration. The oxygen and hydrogen will be produced by electrolysis of water from In Situ Resource Utilization (ISRU) reactors. The electrolysis products will be warm high-pressure gases, requiring significant cryocooler power to achieve the desired storage conditions. This power can be reduced by expanding the gases adiabatically from the electrolysis pressure to storage pressure. We propose to develop innovative turboalternators to maximize this effect and convert the extracted fluid power into useful electric power. Small flow rates and high fluid densities require turbine rotors that are extremely small and operate at high speeds. Cryogenic gas bearings and miniature rotor fabrication techniques are key features that create high efficiency in our approach. The gas bearings also enable reliable, long-life, maintenance-free operation. The proposed development will leverage decades of Creare experience with cryogenic gas-bearing turbomachines. In Phase I, we developed optimized turboalternator designs by conducting trade studies, specifying design details, analyzing performance, and demonstrating bearing operation with two-phase rotor flow. During Phase II, we will create a complete set of fabrication drawings, develop critical fabrication processes, fabricate a prototype turboalternator, and measure its performance at representative operating conditions.

Description

This paper presents results from the 8th Annual Study using Army Corp of Engineers funds of nesting by the Atlantic Loggerhead sea turtle Caretta caretta along the Atlantic Ocean coastline in Virginia Beach, Virginia during 2000. All surveys were implemented by volunteers and staff of the Back Bay National Wildlife Refuge, Virginia Beach, Virginia, throughout the sea turtle nesting season. Two seasonal, fulltime biological technicians were hired to search twentyfive miles of beach along the northern periphery of the nesting range of the Atlantic Loggerhead. Refuge biologists investigated two Loggerhead sea turtle crawls during the 2000 nesting season. The successful nesting attempt for the 2000 nesting season occurred July 11, 2000 on Back Bay NWR, 2.6 miles south of the Refuge beach ramp. It produced a nest of 112 eggs. Refuge employees captured the nesting Loggerhead female and Virginia Institute of Marine Science personnel applied flipper tags and a satellite transmitter. A second crawl, located at the southern end of False Cape State Park, provided no evidence of a nest. An employee at False Cape State Park sighted a third sea turtle crawl, however, tides obliterated it before the sighting could be confirmed. No nests or crawls were located along the oceanfronts of Sandbridge, the Virginia Beach Resort Area, or Fort Story. Night patrols were conducted from June 5June 29 and July 26August 4 by volunteers and Refuge employees, however no turtle was sighted or captured during this period. This report also includes an analysis of Loggerhead sea turtle nests and stranding data from 1980 to 2000.

Description

The Clean Air Status and Trends Network (CASTNET) is a national air quality monitoring network designed to provide data to assess trends in air quality, atmospheric deposition, and ecological effects due to changes in air pollutant emissions. CASTNET began collecting measurements in 1991 with the incorporation of 50 sites from the National Dry Deposition Network, which had been in operation since 1987. CASTNET provides long-term monitoring of air quality in rural areas to determine trends in regional atmospheric nitrogen, sulfur, and ozone concentrations and deposition fluxes of sulfur and nitrogen pollutants in order to evaluate the effectiveness of national and regional air pollution control programs. CASTNET operates more than 80 regional sites throughout the contiguous United States, Alaska, and Canada. Sites are located in areas where urban influences are minimal.

Description

This digital geospatial data set contains the locations, values, and uncertainties of hydraulic-head observations used in the calibration of the transient model of the Death Valley regional ground-water flow system (DVRFS). The hydraulic-head observations were developed by compositing one or more water-levels measured in wells throughout the DVRFS model domain, a 45,000 square-kilometer region of southern Nevada and California. To develop hydraulic-head observations, nearly all available water levels for the DVRFS region through 2004 were compiled in Ground-Water Site Inventory (GWSI), the ground-water component of the U.S. Geological Survey (USGS) National Water Information System (NWIS) database. Water levels suitable for developing hydraulic-head observations representative of regional, steady-state (pre-pumping) and transient (affected by pumping) ground-water flow conditions were identified through analyses. The resulting water levels were averaged by year and for each well to produce 4,899 hydraulic-head observation values at 868 wells. The uncertainty of each hydraulic-head observation was statistically quantified from the values of uncertainties associated with well altitude and location, nonsimulated transient stress, measurement accuracy, model discretization, and pumpage estimates.
