Water levels (November 11 2016 through November 11 2017) for four wells and Light intensity data (October 1 2015 through September 2019): from marsh to upland forest, for Moneystump Marsh, Blackwater National Wildlife Refuge, Maryland Water levels (November 11 2016 through November 11 2017) for four wells and Light intensity data (October 1 2015 through September 2019): from marsh to upland forest, for Moneystump Marsh, Blackwater National Wildlife Refuge, Maryland
Water levels in meters from four wells in Moneystump marsh at Blackwater National Wildlife Refuge, MD. Two wells are located in the upland forest; one well is located in the marsh-forest transition zone (ecotone); and one well is located in the marsh. Water depth of the adjacent creek is reported in meters. Data covers the time span from November 11 2016 - November 11 2017. Pressure...
Presence and prevalence of pathogens among amphibians of Catoctin Mountain Park, 2014 Presence and prevalence of pathogens among amphibians of Catoctin Mountain Park, 2014
Data described herein was collected by USGS personnel and the project funded by USGS and the National Park Service (Catoctin Mountain Park) through a FY14 NRPP project involving both agencies and developed to detect the presence and prevalence of ranavirus and chytrid pathogens among amphibians of Catoctin Mountain Park (CATO). Supplemental molecular analyses were performed on behalf of...
In Support of the U.S. Fish and Wildlife Service 3-Bat Species Status Assessment: Summer Mobile Acoustic Transect Analysis In Support of the U.S. Fish and Wildlife Service 3-Bat Species Status Assessment: Summer Mobile Acoustic Transect Analysis
Through the North American Bat Monitoring Program, Bat Conservation International and U.S. Geological Survey (USGS) collaborated with the U.S. Fish and Wildlife Service to provided technical and science support to assistance in U.S. Fish and Wildlife Services' Species Status Assessment ("SSA") for the northern long-eared bat (Myotis septentrionalis), little brown bat (Myotis lucifugus)...
Integrated modeling of climate and land change impacts on future dynamic wetland habitat – a case study from California’s Central Valley Integrated modeling of climate and land change impacts on future dynamic wetland habitat – a case study from California’s Central Valley
This dataset consists of raster geotiff and tabular outputs of annual map projections of land use and land cover for the California Central Valley for the period 2011-2101 across 5 future scenarios. Four of the scenarios were developed as part of the Central Valley Landscape Conservation Project. The 4 original scenarios include a Bad-Business-As-Usual (BBAU; high water, poor management)
MetaIPM MetaIPM
MetaIPM is a Python package (Python Software Foundation 2020) that models meta-population dynamics and continuous growth rates via an integral projection model (IPM) for species living in distinct habitat patches. The package stems from a model that compares invasive carp population control strategies. The package supports differing sex and any organisms living in distinct habitat...
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)...
Water Quality data compiled for Groundwater development leads to decreasing arsenic concentrations in the San Joaquin Valley, California Water Quality data compiled for Groundwater development leads to decreasing arsenic concentrations in the San Joaquin Valley, California
Groundwater arsenic concentrations in the San Joaquin Valley have varied over the decades from 1980 to 2019. This report was compiled to determine whether arsenic concentrations are increasing or decreasing and the mechanism controlling the trends. The San Joaquin Valley contains 4,979 wells with arsenic analyses and possible co-detections of any of the following constituents: dissolved...
