The “Glaciers of Glacier National Park Repeat Photography Collection” is a compilation of photographs documenting the retreat of glaciers in Glacier National Park, Montana, U.S.A. (GNP) through repeat photography. The collection is comprised of 58 image pairs, resulting from twenty-two years of U.S.Geological Survey (USGS) field excursions (1997-2019) for the purpose of photographically documentin

The natural resiliency of the New Jersey barrier island system, and the efficacy of management efforts to reduce vulnerability, depends on the ability of the system to recover and maintain equilibrium in response to storms and persistent coastal change. This resiliency is largely dependent on the availability of sand in the beach system. In an effort to better understand the system's sand budget a

High-water marks were collected following Hurricane Sandy, October 29-30, 2012, along the coastal areas of Connecticut, Rhode Island, and Massachusetts. Information on 371 high-water marks that were flagged following Hurricane Sandy is presented in this data release. The general information on the high-water marks presented includes site identification number, location, elevation, quality, type, a

A series of 11 digital flood-inundation maps were developed for a 5.5 mile reach of the Pawcatuck River in Westerly, Rhode Island and Stonington and North Stonington, Connecticut by the U.S. Geological Survey in cooperation with the Town of Westerly, Rhode Island and the Rhode Island Office of Housing and Community Development. The coverage of the maps extends from downstream from the Ashaway Rive

A series of 15 digital flood-inundation shapefiles and grids were developed for a 10.2 mile reach of the Pawtuxet River in West Warwick, Warwick, and Cranston, Rhode Island by the U.S. Geological Survey in cooperation with Rhode Island Emergency Management Agency and U.S. Army Corps of Engineers. The coverage of the maps extends from downstream of Natick Pond Dam near State Route 33/Providence Str

This data release contains eight datasets and metadata related to streamwater constituent load estimation and E. coli bacteria concentration predictions at 15 watersheds in DeKalb County, Georgia for 2012 to 2016 (the water-quality model calibration data goes through 9/22/2017 and the water-quality assurance samples goes through 11/7/2017). Loads were estimated for 15 constituents: biochemical oxy

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 activities and

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 confirmed cases

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 samples were ob

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 coastal protect

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 intended to
