We examined bird and bat mortality at a new 89-turbine windfarm constructed in an environmentally sensitive area in north-central Iowa. The windfarm became operational in November 2001. It is located in cropland between three Wildlife Management Areas (WMA's) with historically high bird use. In the past, migrant and resident waterfowl, shorebirds, raptors, and songbirds moved between the WMA's through the area now occupied by the windfarm. Studies of bird collision mortality in California and elsewhere raised concerns about the possibility of mortalities in this area. From April 15, 2003 and December 15, 2003 we searched for dead animals under 26 randomly selected turbines. Six 76.2 m by 3.0 m transects were maintained...

In 1998, the Florida Fish and Wildlife Conservation Commission's (FWC) Fisheries Independent Monitoring (FIM) program began a long-term monitoring effort of key reef fish populations in the Florida Keys National Marine Sanctuary. This effort was aimed at evaluating the relative abundance, size structure, and habitat utilization of specific reef fish species that are targeted by commercial and recreational fisheries.; Smith,S.G., et al. 2011,Multispecies survey design for assessing reef-fish stocks, spatially explicit management performance, and ecosystem condition. Fisheries Research 109(2011)25-41; Brandt,M.E., et. al. 2009,A Cooperative Multi-agency Reef Fish Monitoring Protocol for the Florida Keys Coral Reef...

The Fisheries Ecology Division (FED, https://swfsc.noaa.gov/GroundfishAnalysis/) of the Southwest Fisheries Science Center (SWFSC) has conducted a midwater trawl survey off central California since 1983 with the primary goal of developing pre-recruit indices for young-of-the-year (YOY) rockfish (Sebastes spp.). The survey also samples numerous other components of the epipelagic micronekton, including other YOY groundfish (such as Pacific hake, Merluccius productus, and sanddab, Citharichthys spp ), coastal pelagic fishes (such as Pacific sardine, Sardinops sagax, and northern anchovy, Engraulis mordax) and other forage species. Additional details regarding the survey methods and results are described in Ralston...

Map of the Hulahula River Area and location of observation sites. This focal watershed provides the greatest opportunity to characterize conditions within and fluxes from the Brooks Range Ecoregion. Though the Foothills region isextensive, the watersheds narrow as they cross the Coastal Plain in the easternpart of the North Slope. Inset shows the location of the seven TEON focal watersheds.

In cooperation with the Puerto Rico Environmental Quality Board, the U.S. Geological Survey (USGS) calculated over 40 different basin characteristics as part of preparing the Puerto Rico StreamStats application. These data were used to update the peak flow and low flow regression equations for Puerto Rico. These datasets are raster representations of various environmental, geological, and land use attributes within the Puerto Rico StreamStats 2020 study area, and will be served in the Puerto Rico StreamStats 2020 application to describe delineated watersheds. The StreamStats application provides access to spatial analytical tools that are useful for water-resources planning and management, and for engineering and...

Map of the Agashashok River Area and location of proposed observation sites (numbered circles). This focal watershed is in the southwest corner of the Arctic LCC and largely drains the Brooks Range ecoregion with a small portion of the lower basin in the Kobuk Ridges and Valleys ecoregion. The braided character of the lower river prevents us from suggesting a long term gaging station in that location. Inset shows the location of the seven TEON focal watersheds.

For each pixel, the geodesic distance and the vertical distance to the closest weather station for precip and for temp were calculated. These three dimensions were combined into a single one for precip and one for temp based on the Euclidean distance. The less distance there is these 3 dimensions (x,y,z), the less uncertainty there is. Higher values mean more uncertainty.
SWPA_alvbsn is a vector dataset of alluvial-fill basin statistics for the Southwest United States. Statistics for each basin include physical details such as area, landcover, elevation, slope and precipitation. Anthropogenic data for basin include landuse, population, and wateruse. The displayed value in Data Basin is a multi-attribute value portraying total (ground and surface) water use in acre-feet per year per square kilometer (WU_TOT_AF / AREA_SQ_KM).

This paper describes an approach to determine the relative accountability that each region and individual nation should bear in reducing atmospheric greenhouse gas. The paper argues that accountability should be based on equity and that all measures of equity for which there are backers should be used in the decision making procedure. Each equity indicator defines a different accountability profile, leading to conflicting prescriptions. Multicriterion decision making methods are seen as having high potential to help design fair compromise profiles, and a methodology is proposed and numerous methods indicated for this purpose. The methodology is illustrated by defining ! 1 different equity indicators and then formulating...

The Mercury Deposition Network (MDN) is a national database of weekly concentrations of total mercury in precipitation and the seasonal and annual flux of total mercury in wet deposition. The data is used to develop information on spatial and seasonal trends in mercury deposited to surface waters, forested watersheds, and other sensitive receptors. The MDN is part of the National Atmospheric Deposition Project (NADP) Network. Analysis of precipitation samples for total- and methylmercury is performed by Frontier Geosciences, Inc., Seattle WA, USA. Frontier Geosciences provides the environmental sciences community with uncompromisingly high-quality contract research, project design and management, and analytical...

Governmental policy options in response to increasing concern over an emerging greenhouse warming are reviewed. These will reflect differing levels of pofitical concem as understanding on the future size and impacts of the greenhouse effect evolves. High levels of concem will place emphasis on the option of limiting C02 emissions by restricting fossil fuel use. This option requires emphasis on energy efficiency and changes in energy supply, with increased use of natural gas, nuclear power or renewable energy sources. The progressive industrialization of the LDCs with the consequent growth in energy demand, may put additional pressure on developed countries to take action on this policy option.

This map represents the percent change from 1971-2000 to 2071-2100 in the average annual amount of water contributed to the stream network, as simulated by the model MC1 under the CSIRO Mk3 future climate projection and A2 anthropogenic emissions scenario. The range of data values is from -73.4% to +69.0%. The mean value is -5.3%. Data values are calculated as (STREAMFLOW(2071-2100) minus STREAMFLOW(1971-2000)) divided by STREAMFLOW(1971-2000). STREAMFLOW data is from MC1 version B60. The dynamic global vegetation model MC1 (e.g. Bachelet et al. 2001) was used to simulate vegetation dynamics, associated carbon and nitrogen cycle, water budget, and wild fire impacts at two study sites in eastern Oregon (Deschutes...
