Data Releases

This data release is a collection of data and field notes documenting snow and ice changes on South Cascade Glacier, Washington, USA. The field records relate to glaciological research and reflect evolving interpretations of glacier mass balance, climatology, hydrology, and other glacier-related research conducted at the site between 1957 to 2022 in association with the USGS Benchmark Glacier Proj

This dataset represents 179 unique adult female northern elephant seals that were sampled between 2011 and 2021 during four different life history states (early breeding, late breeding, early molting, and late molting) at the Ano Nuevo colony in California, USA. Some individual seals were sampled multiple times, resulting in a total of 313 tissue samples. Tissue samples were collected from seals a

Mitigating the effects of salinity (total dissolved solids) and selenium on water quality in the lower Gunnison River Basin (LGRB) of western Colorado is a major concern for land managers. In cooperation with the Bureau of Reclamation, the U.S. Geological Survey completed a study to develop multiple linear regression models to estimate salinity and selenium loads. The objective of the study was to

Data sets collected for manatee movement and habitat research in the Northern Gulf of Mexico from 2013-2019. These include manatee GPS tracking, manatee sightings, aquatic vegetation from manatee use areas, and environmental data (salinity and bathymetry at vegetation sampling sites).

These data were compiled to assess the response of vegetation and biological soil crusts to drought in a semi-arid ecosystem on the Colorado Plateau near Moab, Utah. Objective(s) of our study were to explore how vegetation cover, soil conditions, and growing season nitrogen (N) availability are impacted by multifaceted drying climate conditions using data from a long-term precipitation reduction e

Dataset consists of morphometric measurements from unionid Pondmussel (Ligumia subrostrata) and concentrations of four per- and polyfluoroalkyl substances (PFAS) in water and freshwater mussels collected from a 14-day accumulation and 7-day elimination study. The accumulation of four per- and polyfluoroalkyl substances (PFAS) were measured. Samples (4 replicates) were collected at 0, 4, 12, 48, 96

From 16 June to 30 July, 2021, a Virginia Tech team of 4-6 sampled the fish community in 30 Shenandoah Valley streams (Virginia and West Virginia, USA) as part of a larger stream-health study including other teams who surveyed geomorphology, water quality, flow, temperature, macroinvertebrates, and fish health at the same 30 streams. The fish community team also sampled three additional bonus stre

This data release includes laser ablation inductively coupled plasma mass spectrometry (LA-ICPMS) U-Pb zircon geochronology data from four samples collected from fault-bounded bedrock units in northwestern Oregon. Samples were collected from a paleoseismic trench excavated across the Scoggins Valley strand of the Gales Creek Fault and nearby quarry. The trench is located on a ridge top saddle on t

This Geologic Map Schema (GeMS) database contains all the geologic map information used to publish the Preliminary Surficial Geologic Map of Leuhman Ridge and the Surrounding Area, Edwards Air Force Base and Air Force Research Laboratory, Kern and San Bernardino Counties, California, U.S. Geological Survey Open-File Report 2023-1014. This digital map database represents the general distribution of

The data in the CSV file named RSF is a detailed dataset used to run the models testing relationships between movement behavior and atmospheric conditions. This dataset includes: detection date and rounded hour, status (0 or 1) showing if over-water movement occurring within nine hours was detected, number of hours since sunset, site ID of area weather station, Motus tag ID, wind speed , Temperatu

The US Fish and Wildlife Service (USFWS) is evaluating the status of the Cascade torrent salamander (Rhyacotriton cascadae) across its range to determine whether the species merits listing under the Endangered Species Act. The USGS conducted visual surveys for Rhyacotriton cascadae at 65 sites in Oregon and Washington that were historically occupied by the species. Sites were selected from a pool

These data include geochemical analyses of rock, mine waste, soil, sediment, and water samples collected from the Balkhab copper deposit, Sar-e Pol Province, Afghanistan in 2019.
