The 2002 U.S. Geological Survey (USGS) National Seismic Hazard Maps display earthquake ground motions for various probability levels across the United States and are applied in seismic provisions of building codes, insurance rate structures, risk assessments, and other public policy. This update of the maps incorporates new findings on earthquake ground shaking, faults, seismicity, and geodesy. The resulting maps are derived from seismic hazard curves calculated on a grid of sites across the United States that describe the frequency of exceeding a set of ground motions.

Sagebrush ecosystems in North America have experienced extensive degradation since European settlement, and continue to further degrade from exotic invasive plants, greater fire frequency, intensive grazing practices, increased oil and gas development, climate change, and other factors. Remote sensing is often identified as a key information source to facilitate broad-area ecosystem-wide characterization, monitoring and analysis, however, approaches that characterize sagebrush with sufficient and accurate local detail across large areas to support ecosystem research and analysis are unavailable. We have developed a new remote sensing sagebrush ecosystem characterization approach for the state of Wyoming, U.S.A....
All FRCC calculations were done in ArcGIS 9.3.1 with the FRCC Mapping Tool version 2.2.0, using Landfire Biophysical Settings (BpS) and Succession Class (S-Class) layers and the default Landfire Reference Condition table (LFnat_west). All calculations were performed at a 30-meter resolution. Input BpS and S-Class layers were downloaded using the Landfire Data Access Tool version 2.2 (configuration database version 1.27, feature database version 1.02). Three landscape levels were used in all calculations, the 4th, 5th and 6th field HUCs from the "Pacific NW Sixth Field Hucs" GIS layer from Bonneville Power Administration (Subbasins, Watersheds and Subwatersheds, resp.). FRCC Calculation Procedure For each of the...
The British Columbia Marine Conservation Analysis (BCMCA) is a collaborative project assembling and analyzing spatial information about Canada's Pacific Ocean. The overall goal of the BCMCA is to identify marine areas of high conservation value and marine areas important to human use. Results of the project are intended to inform and help advance marine planning initiatives in BC by providing collaborative, peer-reviewed scientific analyses based on the best ecological and human use spatial data at scales relevant to a BC coast-wide analysis.
This dataset contains small cutthroat trout lakes within Southeast Alaska. These are smaller lakes that do not produce cutthroat trout large enough to reach the 11-inch regional minimum size limit. Each of these lakes has a 9-inch minimum size limit, and bait is prohibited. Regionwide limits of 2 per day and 2 in possession apply. Currently there are seven lakes in Southeast Alaska with the small cutthroat lake designation. Please verify fishing regulations with current Alaska Department of Fish and Game Sport Fishing Regulations at the following link: http://www.adfg.alaska.gov/index.cfm?adfg=fishregulations.se_sportfish
This data represents the location of coastal British Columbia marine kayaking routes.
The Monthly Projected Soil Moisture at Bottom Layer (SMBT) data sets are part of the downscaled global climate models created for the 2008 California climate change assessment. These files are made from daily data and are monthly mean values in millimeters. SMBT layers have been created through a Bias Corrected Statistical Downscaling (BCSD) approach and are currently available for the cnrmcm3, gfdlcm21, ncarccsm3, and ncarpcm1 models under the A2 and B1 scenarios. The BCSD data cover 31.9375N to 43.9375N and 124.5625W to 113.0625W. The VIC grid is a 1/8th degree grid so this makes a "box" of 93 longitudes by 97 latitudes. The VIC computations are done over land only. For the 93x97 box there would be a total of...
This data set represents the spatial distribution of the commercial halibut fishery within the International Pacific Halibut Commission's statistical areas for British Columbia and was provided by the IPHC. The statistical areas were digitized by the IPHC and most vertices coincide with the historical IPHC areas. For accurate digitization, additional vertices were inserted by referring to NOAA (National Oceanic and Atmospheric Administration) and CHS (Canadian Hydrographic Survey) Mercator projected charts. The BCMCA used the statistical areas to join the aggregated catch information from 1991-2006, also provided by the International Pacific Halibut Commission. Catch data is assigned to statistical areas using (in...
The Towboat reserves were put in place at the request of the Council of Marine Carriers (CMC) to protect harbours along the BC Coast to ensure harbours of refuge (temporary shelter during inclement weather or when waiting for favorable tides) remained available for commercial marine traffic - eg. tugs towing booms and barges up and down the coast. These harbours needed to be of adequate size, be located along commercial navigation routes and provide adequate shelter to accommodate the tug and the load being towed. Certain harbours were identified as critical harbours because they meet the size, location and shelter criteria required. To ensure the harbour remains available as a harbour refuge, shoreline development...

This data represents the location of coastal British Columbia coastal campsites, kayak use sites and kayak staging areas.
The Humpback Shrimp catch grid dataset has been assembled directly from the Shellfish Data Units harvest log database located at the Pacific Biological Station (PBS). The dataset has been modified to meet the sensitive nature of the data as per the Access to Information Act20(1)(b,c); which specifies that Fisheries and Oceans Canada will not disclose to a third party confidential information that may prejudice the competitive position of the fisher, in which fishing location has been identified as one of the entities to be protected. There was a 10km x 10km grid used in the desensitization process as well information was limited to total Effort (kilometre) and total Catch (lbs). The dataset is comprised of Humpback...

Water scarcity is a growing concern in Texas, where surface water is derived almost entirely from rainfall. Changes in air temperature and precipitation patterns associated with global climate change are anticipated to regionally affect the quality and quantity of inland surface waters and consequently their suitability as habitat for freshwater life. In addition to directly affecting resident organisms and populations, these changes in physicochemical traits of aquatic habitats may favor the establishment of harmful invasive species. As conflicts over the use of water resources grow in intensity, this information will become important for fish and wildlife managers to anticipate impacts of climate change on trust...

This data set represents the extent, approximate location and type of wetlands and deepwater habitats in the United States and its Territories. These data delineate the areal extent of wetlands and surface waters as defined by Cowardin et al. (1979). Certain wetland habitats are excluded from the National mapping program because of the limitations of aerial imagery as the primary data source used to detect wetlands. These habitats include seagrasses or submerged aquatic vegetation that are found in the intertidal and subtidal zones of estuaries and near shore coastal waters. Some deepwater reef communities (coral or tuberficid worm reefs) have also been excluded from the inventory. These habitats, because of their...

Maintaining the native prairie lands of the Northern Great Plains (NGP), which provide an important habitat for declining grassland species, requires anticipating the effects of increasing atmospheric carbon dioxide (CO2) concentrations and climate change on the region’s vegetation. Specifically, climate change threatens NGP grasslands by increasing the potential encroachment of native woody species into areas where they were previously only present in minor numbers. This project used a dynamic vegetation model to simulate vegetation type (grassland, shrubland, woodland, and forest) for the NGP for a range of projected future climates and relevant management scenarios. Comparing results of these simulations illustrates...
