SPARROW model input datasets and predictions of total dissolved loads in streams of the Upper Colorado River Basin watershed SPARROW model input datasets and predictions of total dissolved loads in streams of the Upper Colorado River Basin watershed
This data release contains bootstrap values of mean-annual total dissolved solids (TDS) loads predicted by a SPARROW model for individual stream reaches in the Upper Colorado River Basin watershed in the predict.txt file. Also included are the input variables required to execute the model, including dissolved solids sources, landscape characteristics, and calibration data from water...
Distribution and Abundance of Least Bell's Vireos (Vireo bellii pusillus) and Southwestern Willow Flycatchers (Empidonax traillii extimus) on the Middle San Luis Rey River, San Diego County, Southern California in 2021 Distribution and Abundance of Least Bell's Vireos (Vireo bellii pusillus) and Southwestern Willow Flycatchers (Empidonax traillii extimus) on the Middle San Luis Rey River, San Diego County, Southern California in 2021
We surveyed for Least Bell's Vireos (Vireo bellii pusillus; vireo) and Southwestern Willow Flycatchers (Empidonax traillii extimus; flycatcher) along the San Luis Rey River, between College Boulevard in Oceanside and Interstate 15 in Fallbrook, California (middle San Luis Rey River), in 2021. Surveys were conducted from April 13 to July 14 (vireo) and from May 18 to July 13 (flycatcher)...
Combined High-Resolution Topography and Bathymetry for Western Passage Canal, Near Whittier, Alaska Combined High-Resolution Topography and Bathymetry for Western Passage Canal, Near Whittier, Alaska
This dataset is a new Digital Elevation Model (DEM) using the best available high-resolution topography and bathymetry surrounding the area of Whittier, Alaska. We utilized three datasets (1) LiDAR topography collected by the Alaska Division of Geological and Geophysical Surveys (DGGS) in 2012, (2) multibeam echosounder system (MBES) survey of western Passage Canal collected by the USGS...
Locations of Pacific Flyway Ducks in and near Commercial Livestock Facilities of the Western USA (2015-2021) Locations of Pacific Flyway Ducks in and near Commercial Livestock Facilities of the Western USA (2015-2021)
Zoonotic diseases are of considerable concern to the human population and viruses such as avian influenza (AIV) threaten food security, wildlife conservation and human health. Wild waterfowl and the natural wetlands they use, are known AIV reservoirs, with birds capable of virus transmission to domestic poultry populations. While infection risk models have linked migration routes and AIV...
Gridded Data from Multibeam Bathymetric Surveys of Eklutna, Kenai, and Skilak Lakes, Alaska Gridded Data from Multibeam Bathymetric Surveys of Eklutna, Kenai, and Skilak Lakes, Alaska
This dataset contains bathymetric depth values for three lakes in southcentral Alaska: Eklutna Lake near the city of Anchorage, Kenai Lake near the city of Cooper Landing, and Skilak Lake near the city of Soldotna. Values are in negative meters and measured relative to the North American Vertical Datum of 1988. The data release consists of a raster grids (Eklutna = 4 m; Kenai = 9 m...
Data release for luminescence: Edwards Air Force Base (CA) and CA Water Science Center report including luminescence data and ages Data release for luminescence: Edwards Air Force Base (CA) and CA Water Science Center report including luminescence data and ages
The following report summarizes the dating results from Aeolian deposits within and around Edwards Air Force Base in California. Within this report, we detail the methodology used by the USGS Luminescence Geochronology Laboratory to obtain ages including sample preparation methods, luminescence measurement, equivalent dose determination, and dating related calculations. We recommend that...
