Great Lakes Coastal Wetland Restoration Assessment (GLCWRA) Lake Ontario, U.S. Great Lakes Coastal Wetland Restoration Assessment (GLCWRA) Lake Ontario, U.S.
This dataset is part of the U.S. Geological Survey (USGS) Great Lakes Coastal Wetland Restoration Assessment (GLCWRA) initiative. The GLCWRA initiative uses principles of geodesign to identify coastal wetland areas that have the greatest potential for habitat restoration. The data model uses the following seven primary parameters to identify and rank wetland restoration areas. The...
Trace of the lower Las Vegas Wash study area, 2017 Trace of the lower Las Vegas Wash study area, 2017
This vector line dataset represents the lower Las Vegas Wash study area. Surface-water trace was digitized onscreen from Landsat8 and ESRI World Imagery. The trace is used in an accompanying surface-water study to evaluate discharge gains and losses at selected locations in the Lower Las Vegas Wash.
Locations and Properties of Ice-Exposing Scarps and New Impact Craters in the Mid-Latitudes of Mars Locations and Properties of Ice-Exposing Scarps and New Impact Craters in the Mid-Latitudes of Mars
Although ice in the Martian mid-latitudes is typically covered by a layer of dust or regolith, it is exposed in some locations by fresh impact craters or in erosional scarps. In both cases, the exposed ice is massive or excess ice with a low lithic content. We find that erosional scarps occur between 50-61 north and south latitude, and that they are concentrated in and near Milankovi...
In Support of the U.S. Fish and Wildlife Service 3-Bat Species Status Assessment: Wind Energy Influence In Support of the U.S. Fish and Wildlife Service 3-Bat Species Status Assessment: Wind Energy Influence
Through the North American Bat Monitoring Program, United States Geological Survey (USGS) provided technical and science support to assist in U.S. Fish and Wildlife Services' Species Status Assessment ("SSA") for the northern long-eared bat (Myotis septentrionalis), little brown bat (Myotis lucifugus), and tri-colored bat (Perimyotis subflavus). USGS facilitated the SSA data call...
Morphometric and Reproductive Status Data for Sea Otters Collected or Captured in Alaska Morphometric and Reproductive Status Data for Sea Otters Collected or Captured in Alaska
This dataset includes morphometric measurements and pregnancy / dependency status from sea otters captured or collected (experimental harvests or recovered after the Exxon Valdez Oil Spill) in Alaska, 1947-2019 by the U.S. Geological Survey (USGS) and the U.S. Fish and Wildlife Service (USFWS). Data collected include total body length, tail length, body mass, axillary girth, paw width...
Data and Results for GIS-Based Identification of Areas that have Resource Potential for Sediment-Hosted Pb-Zn Deposits in Alaska Data and Results for GIS-Based Identification of Areas that have Resource Potential for Sediment-Hosted Pb-Zn Deposits in Alaska
This data release contains the analytical results and the evaluated source data files of a geospatial analysis for identifying areas in Alaska that may have potential for sediment-hosted Pb-Zn (lead-zinc) deposits. The spatial analysis is based on queries of statewide source datasets Alaska Geochemical Database (AGDB3), Alaska Resource Data File (ARDF), and Alaska Geologic Map (SIM3340)...
