Data Releases
The data collected and the techniques used by USGS scientists should conform to or reference national and international standards and protocols if they exist and when they are relevant and appropriate. For datasets of a given type, and if national or international metadata standards exist, the data are indexed with metadata that facilitates access and integration.

Data release for Climatically driven displacement on the Eglington fault, Las Vegas, Nevada, USA
The Eglington fault is one of several intrabasinal faults in the Las Vegas Valley, Nevada, USA, and is the only one recognized as a source for significant earthquakes. Its broad warp displaces Late Pleistocene spring deposits of the Las Vegas Formation, which record hydrologic fluctuations that occurred in response to millennial- and submillennial-scale climate oscillations throughout the late Qua
Velocity and water-quality surveys in the Ohio River between Markland Locks and Dam and McAlpine Locks and Dam, Kentucky and Indiana, October 27-November 4, 2016, and June 26-29, 2017
Velocity and water-quality surveys were completed along an approximately 71-mile reach of the Ohio River between Markland Locks and Dam (river mile 531.5) and McAlpine Locks and Dam (river mile 606.8) on October 27-November 4, 2016 (survey #1), and June 26-29, 2017 (survey #2). Water-quality data collected in this reach included surface measurements and vertical profiles of water temperature, spec
Digital map of iron sulfate minerals, other mineral groups, and vegetation of the San Juan Mountains, Colorado, and Four Corners Region derived from automated analysis of Landsat 8 satellite data
Multispectral remote sensing data acquired by the Landsat 8 Operational Land Imager (OLI) sensor were analyzed using a new, automated technique to generate a map of exposed mineral and vegetation groups in the western San Juan Mountains, Colorado and the Four Corners Region of the United States (Rockwell and others, 2021). Spectral index (e.g. band-ratio) results were combined into displayed miner
Digital map of iron sulfate minerals, other mineral groups, and vegetation of the western United States derived from automated analysis of Landsat 8 satellite data
Multispectral remote sensing data acquired by Landsat 8 Operational Land Imager (OLI) sensor were analyzed using an automated technique to generate surficial mineralogy and vegetation maps of the conterminous western United States. Six spectral indices (e.g. band-ratios), highlighting distinct spectral absorptions, were developed to aid in the identification of mineral groups in exposed rocks, soi
Groundwater Well Yield in Wake County, North Carolina
The U.S. Geological Survey, in cooperation with Wake County Environmental Services, initiated a comprehensive groundwater resource investigation to better understand the quantity and quality of groundwater in Wake County, North Carolina. In 2020, as part of the investigation, groundwater records were compiled electronically from 7,689 wells in and within five miles of Wake County and groundwater y
Land Cover Basin Characteristics Rasters for South Carolina StreamStats 2021
In cooperation with the South Carolina Department of Transportation, the U.S. Geological Survey calculated four land cover basin characteristics rasters as part of preparing the South Carolina StreamStats 2021 application. These datasets are raster representations of impervious surface, developed, forested, and storage land cover attributes within the South Carolina StreamStats 2021 study area, an
Immunological histopathology of American kestrels (Falco sparverius) exposed to the flame retardant isopropyl triphenyl phosphate
This work is part of a study of the immunological effects of exposure to alternative flame retardants in avian species. For the pathology portion of the study, hatchling American kestrels (Falco sparverius) were exposed to the flame retardant isopropyl triphenyl phosphate (ITP) and then challenged with a synthetic analogue of viral double-stranded RNA, polyinosinic:polycytidylic acid (poly I:C). C
Immunological histopathology of American kestrels (Falco sparverius) exposed in ovo to two persistent organic pollutants -- SCCPs and TBBPA-BDBPE
This work is part of a study of the immunological effects of exposure to alternative flame retardants in avian species. For the pathology portion of the study, spleens and bursas from American kestrels (Falco sparverius) exposed by egg injection to varying doses of short-chain chlorinated paraffins (SCCPs) and the flame retardant TBBPA-BDBPE were examined microscopically for architectural and cell
Bayou Sauvage NWR (LA) Haul Trail Snake Mortality, 2015-2017
Comprehensive list of carcasses detected at Haul Trail in Bayou Sauvage National Wildlife Refuge (Orleans Parish, LA) and relevant findings for specimens subject to postmortem examination at the USGS National Wildlife Health Center (Madison, WI).
Necropsy reference number and summary collection information for Washington state population of northern sea otters examined during 1989-2010
Morbillivirus epidemics in marine mammals first gained prominence in 1988 when an outbreak of phocine distemper virus (PDV) occurred in European harbor seals (Phoca vitulina vitulina). Prior to 2001, all serosurveys for morbilliviruses in sea otters (Enhydra lutris) in California, Washington and Alaska documented a 0% seroprevalence. The first published serodetections of morbillivirus in sea otter
Vegetation and Temperature Data, Smith River Estuary, Alaska, 2011-2013
This data release contains measurements of vegetation samples and temperature collected from experimental plots of Carex subspathacea along the Smith River Estuary, Alaska (2011-2013).
Multi-element geochemical analyses of samples from the Mesoproterozoic Nonesuch Formation and Copper Harbor Conglomerate at the Copperwood copper deposit, Western Syncline, Michigan, USA
This data release provides multi-element data for drill core samples from the Mesoproterozoic Nonesuch Formation and Copper Harbor Conglomerate at the Copperwood copper deposit, Michigan, USA. Copper was determined by assay, and sulfur by inductively coupled plasma-optical emission spectrometry (ICP-OES) after aqua regia digestion for most samples. Multi-element whole rock analyses were determined
