Description

The Double0 Plan is a stepdown plan of the 1985 Refuge Master Plan and Environmental Assessment. The purpose of this plan is to guide the management, protection, and restoration of habitat on the Double0 Unit of the Malheur Refuge. Although this is a longrange plan , it will be evaluated after five years and will be updated as better management information is developed or to reflect changes in resource priorities. This plan will focus on the goal of improving wildlife habitat at the Double0 Unit. Major actions will include: 1 protection of sensitive habitats and sites such as Research Natural Areas and archaeological sites; 2 Haying, grazing and burning of meadow vegetation to enhance habitat for spring feeding and breeding activity for waterbirds and nesting shorebirds; 3 management of water supplies to provide additional late season brood water; 4 maintenance and enhancement of nesting cover in uplands, marshes, meadows and riparian areas; 5 elimination of interior fencing to reduce wildlife losses; 6 development of a grain field to provide a fall feeding and staging area for greater sandhill cranes; and 7 restoration of willow riparian zones that once existed downstream from the springheads and along Silver Creek. Two issues which have a major influence on wildlife viability at Double0 are addressed in this plan. These issues are 1 management of limited water supplies for the benefit of wildlife species and 2 management of vegetation to enhance habitat conditions for wildlife species. Other issues which have a direct impact on the habitat, specifically carp and predators, are covered in depth in other management plans. Refuge land management practices will change with implementation of this plan. It will result in a reduction from 2400 to 1500 acres grazed. Areas to be managed by haying will increase from about 350 acres a year to 750. Areas to be managed using prescribed burning will increase from about 50 acres a year to an average of 700 acres a year. The remaining 15,600 acres of the Double0 Unit will remain idle under this plan. The total estimated cost to enhance habitat under this plan is 115,000 over a fiveyear period.

Description

A largescale lake study on Interior Alaska National Wildlife Refuges NWR was undertaken from 19841986. Six NWRs were surveyed Innoko, Kanuti, Koyukuk, Nowitna, Tetlin, and Yukon Flats and lakespecific habitat and fish data were collected from 135 lakes, though a comprehensive report of the findings was never published. This Alaska Fisheries Data Series Report presents these data, allowing public access to this important information. Lake locations, reference and bathymetric maps, lake habitat descriptions, and fisheries data are organized and presented. Lowland lakes were most commonly sampled 74, followed by foothill 31 and oxbow 30 lakes. The highest elevation and deepest sampled lakes were in Tetlin NWR. The highest water quality measurements conductivity, total alkalinity, total hardness, and pH came from Yukon Flats NWR lakes. Of the 135 lakes sampled, 102 lakes contained fish. A total of 15 fish species were collected throughout the study, with Tetlin NWR lakes having the highest species diversity 9 species and Nowitna and Yukon Flats NWRs having the lowest 6 species. Humpback whitefish Coregonus clupeaformis, least cisco C. sardinella, and northern pike Esox lucius had the widest distribution, being present in all six refuges. The highest frequencies of fish occurrence were in oxbow and lowland lakes, lakes with river connections, and lakes with high flood potential. Foothill lakes and lakes without river connections had the lowest probability of fish capture. Koyukuk NWR had the most sampled lakes containing fish 96 and Yukon Flats NWR had the fewest sampled lakes with fish present 49. Northern pike was the most ubiquitous species, occurring in 90 of all lakes containing fish. Fish species diversity was highest in lakes with river connections 14 species.

Description

The U.S. Geological Survey (USGS) has generated and mapped isobioclimate classes for the contiguous United States. These isobioclimate classes were created as part of an effort to map standardized, terrestrial ecosystems for the nation using a classification developed by NatureServe (Comer and others, 2003). Ecosystem distributions were modeled using a biophysical stratification approach developed for South America (Sayre and others, 2008) and now being implemented globally (Sayre and others, 2007). Bioclimate regimes strongly influence the differentiation and distribution of terrestrial ecosystems, and are one of the key input layers in the ecosystem delineation process. The Rivas-Martínez methodology used to produce these classes was developed from a consideration of bioclimatology and its relationship to phytogeography (Rivas-Martínez, 2004; Rivas-Martínez and others, 1999, 2004). This approach develops a number of bioclimatic indices calculated from a variety of data on temperature and precipitation (e.g. average temperature of the coldest month, total precipitation of the warmest four-month period, a continentality index and a thermicity index). Daymet data, which was developed from 18-year (1980-1997) climatological records and is available at a spatial resolution of 1 kilometer, was used as the source data for these indices (Thornton, 1997). Once calculated the values of these indices are compared to established thresholds for the differentiation of thermotypic (warm/cold gradients) and ombrotypic (wet/dry gradients) regions, and the results are used in sets of decision rules to identify classes. The classification is implemented in four levels: macrobioclimates, bioclimates, thermotypes (thermoclimatic belts) and ombrotypes (ombroclimatic belts). The final isobioclimates dataset represents areas of the 127 unique thermotype-ombrotype combinations that were mapped for the contiguous United States.

Description

Habitat maps of Puerto Rico and the U.S. Virgin Islands were created by visual interpretation of aerial photographs using the Habitat Digitizer Extension. Aerial photographs are valuable tools for natural resource managers and researchers since they provide an excellent record of the location and extent of habitats. However, spatial distortions in aerial photographs due to such factors as camera angle, lens characteristics, and relief displacement must be accounted for during analysis to prevent incorrect measurements of area, distance, and other spatial parameters. These distortions of scale within an image can be removed through orthorectification. During orthorectification, digital scans of aerial photos are subjected to algorithms that eliminate each source of spatial distortion. The result is a georeferenced digital mosaic of several photographs with uniform scale throughout the mosaic. Features near land are generally georeferenced with greater accuracy while the accuracy of features away from land is generally not as good. Where no land is in the original photographic frame only kinematic GPS locations and image tie points were used to georeference the images. After the orthorectified mosaics were created, photointerpreters were able to accurately and reliably delineate boundaries of features in the imagery as they appear on the computer monitor.

Description

This digital data set delineates the boundary of the Death Valley region that was first evaluated by the U.S. Geological Survey (USGS) as a potential hydrogeologic environment for isolation of high-level radioactive waste in 1981. Identifying potential high-level waste isolation regions within the Basin and Range physiographic province continued through the 1980's and resulted in comprehensive geologic and hydrologic characterization of select areas. As part of these studies, Bedinger and others (1989) evaluated the Death Valley region, an area of about 80,200-square kilometers in southern Nevada and California, with respect to the geology at repository target depths, ground-water flow, potential transport of radionuclide material, mineral and energy resources, geomorphic processes, tectonic hazards, and the effects of climatic and geomorphic change on the ground-water system. The study by Bedinger and others (1989) served as one of the historical references used to support development of the transient ground-water model of the Death Valley regional ground-water flow system (DVRFS) completed in 2004 by the USGS (see "Larger Work Citation").

Notice: If you are having difficulties subsetting SNODAS data via Polaris, please contact nsidc@nsidc.org. This data set contains output from the NOAA National Weather Service's National Operational Hydrologic Remote Sensing Center (NOHRSC) SNOw Data Assimilation System (SNODAS). SNODAS is a modeling and data assimilation system developed by NOHRSC to provide the best possible estimates of snow cover and associated parameters to support hydrologic modeling and analysis. The aim of SNODAS is to provide a physically consistent framework to integrate snow data from satellite, airborne platforms, and ground stations with model estimates of snow cover (Carroll et al. 2001). SNODAS includes procedures to ingest and downscale output from the Numerical Weather Prediction (NWP) models, and to simulate snowcover using a physically based, spatially-distributed energy- and mass-balance snow model. SNODAS also includes procedures to assimilate satellite-derived, airborne, and ground-based observations of snow covered area and Snow Water Equivalent (SWE). These data are not suitable for snow fall events or totals for specific regions. For snow fall data, please see the state climatology reports for a particular state. These are gridded data sets for the continental United States at 1 km spatial resolution and 24 hour temporal resolution. Data are stored in flat binary 16-bit signed integer big-endian format with header and metadata files, and are available from 1 October 2003 to present via FTP.

Description

We will fabricate and test microfluidic designs for a micro-electromechanical system based complete blood count (CBC) analysis in separate modules and integrate them into a working prototype. A first module constitutes a hydrodynamic focusing injector and cell impedance meter. A second module takes hydrodynamically focused cells and measures light scatter in the forward and orthogonal directions, as well as of fluorescence emission intensities from specific cell types using novel signal collection designs and micrometer scale, and Geiger-mode avalanche photodiodes that produce time-correlated photocount statistics from multiple optical sources. The third module will serve for blood sample dilution, routing, automated lysing and removal of human erythrocytes. This unit will also incorporate a sensor for measuring hemoglobin (Hgb) concentration. The proposed blood analyzer will utilize innovative optical and fluidic designs on a modular platform that enable compactness, high sensitivity, and robust service, while requiring no operator intervention.

Description

Colorado Power Electronics is in the process of completing NASA SBIR contract NNC07CA12C Wide Output Range Power Processing Unit for Electric Propulsion. At the end of the project, we will have a complete brassboard PPU except for the Digital Control and Interface Unit (DCIU) and Flow Control Driver. The brassboard PPU meets the electrical requirements of the project, but the specific mass is about 20% too low compared to the first bullet of the solicitation. Preliminary results from testing a 4 kW discharge supply show that the full-power efficiency ranges from 94% to 96%. This proposal is to: (1) Determine ways to reduce the mass of the brassboard PPU (2) Evaluate the brassboard PPU to determine robustness improvements to be implemented in Phase II. (3) Determine requirements for a DCIU to be implemented in Phase II. (4) Design and build a brassboard Flow Control Driver (5) Gain experience in controlling gas flow The Flow Control Driver will be designed to control a xenon gas flow system selected by NASA. The DCIU design will be based on requirements received from NASA. The significance of this project is that it makes improvements to an innovative and promising PPU technology, moving it closer to a flight-ready product, while also facilitating NASA research with advanced flow controls.
