USGS Chesapeake Bay Study Locations Related to Theme 1 and Theme 2 Activities (ver. 3.0, October 2024) USGS Chesapeake Bay Study Locations Related to Theme 1 and Theme 2 Activities (ver. 3.0, October 2024)
This data includes point and polygon layers that are a compilation of study sites, watersheds, and areas of interest associated with the USGS Chesapeake Bay Theme 1 (factors affecting stream health, fish habitat, and aquatic conditions) and Theme 2 (coastal Habitats and Implications for Waterbirds) activities. Locations in this dataset were compiled from various USGS Chesapeake Bay...
Confirmed cases of snake fungal disease in historical museum specimens Confirmed cases of snake fungal disease in historical museum specimens
Snake fungal disease (SFD) represents a conservation threat to wild snake populations. The disease was reported in North America early in the 21st century, but the history of SFD has not been investigated. We examined museum specimens and confirmed cases of SFD based on clinical signs, histopathologic lesions, and detection of the causative agent Ophidiomyces ophidiicola. The first...
Genetic Data from Wolverine (Gulo gulo) of North America Genetic Data from Wolverine (Gulo gulo) of North America
These data are comprised of two tables, one table containing wolverine (Gulo gulo) sample and genetic information for 20 microsatellite loci (Gg10-1, Gg25, Gg37-2, Gg42-1, Gg192-1, Gg443, Gg452, Gg454, Gg465, Gg471, Gg473, Gg-3-1, Gg-4, Gg-7-1, Ggu_216-1, Lut604, Ma-3-1, Mvis075, Tt-1, and Tt-4) and genetic sex determination results from North America and one Russian wolverine. All...
Model parameter input files to compare locations of coral reef restoration on different reef profiles to reduce coastal flooding Model parameter input files to compare locations of coral reef restoration on different reef profiles to reduce coastal flooding
This dataset consists of physics-based XBeach Non-hydrostatic hydrodynamic models input files used to study how coral reef restoration affects waves and wave-driven water levels over coral reefs, and the resulting wave-driven runup on the adjacent shoreline. Coral reefs are effective natural coastal flood barriers that protect adjacent communities. Coral degradation compromises the...
Hydrologic data in Hinkley and Water Valleys, San Bernardino County, California, 2015-2018 Hydrologic data in Hinkley and Water Valleys, San Bernardino County, California, 2015-2018
Data were collected to help define hydrologic controls on groundwater movement as part of a U.S. Geological Survey (USGS) study on background concentrations of hexavalent chromium in groundwater aquifers near Hinkley, California. Most data associated with the background study are available through the National Water Information System (NWIS) website, and GeoLog Locator. This product is...
Model parameters and output of net ecosystem carbon balance for the Great Dismal Swamp, Virginia and North Carolina, USA Model parameters and output of net ecosystem carbon balance for the Great Dismal Swamp, Virginia and North Carolina, USA
In this study, we determined the carbon balance in the Great Dismal Swamp, a large forested peatland in the southeastern USA, which has been drained for over two hundred years and now is being restored through hydrologic management. We modeled future net ecosystem carbon balance over 100 years (2012 to 2112) using in situ field observations paired with simulations of water-table depth...
