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.

Amphibian and Reptile Assemblages of Stream and Pond Habitats in Coastal Southern California (1996-2026) Amphibian and Reptile Assemblages of Stream and Pond Habitats in Coastal Southern California (1996-2026)
These data represent 30 years of observation data following stream survey protocols for stream and pond associated reptiles and amphibians. Species observations were made following methods for visual encounter and trapping surveys using both passive and baited turtle and minnow traps.
AmphiTraits: A Database of Life History Traits of Amphibian Species in the USA AmphiTraits: A Database of Life History Traits of Amphibian Species in the USA
Knowledge of species traits is critical for conservation. Many large databases of species traits are available, but their use is often limited by data completeness, taxonomic coverage, and/or specificity of traits being assessed. We produced a database of traits for amphibian species native to the continental USA, reducing the total number of traits presented by other databases while...
Hydrophone data from gravel-bedded rivers in Washington and Idaho, 2019 to 2024 Hydrophone data from gravel-bedded rivers in Washington and Idaho, 2019 to 2024
Hydrophones have been proposed as a potential surrogate for bedload transport, operating on the principle that particle collisions generate sound that scales in intensity with transport rate (for example, Geay and others, 2017). To assess that potential, the U.S. Geological Survey (USGS) partnered with the Washington Department of Transportation (WSDOT) in 2019 to install hydrophones on...
Topographic Differencing Analyses on Glacier Creek, Washington, from 2005 to 2022 Topographic Differencing Analyses on Glacier Creek, Washington, from 2005 to 2022
Glacier Creek drains a 82 square kilometer watershed that includes multiple glaciers on the north flank of Mount Baker in Whatcom County, Washington. The Washington State Department of Transportation (WSDOT) maintains a bridge along Highway 542 over Glacier Creek near its confluence with the North Fork Nooksack River, where Glacier Creek has formed an alluvial fan. To assist in WSDOT...
Particle size and X-ray diffraction data for surficial samples collected on Etosha Pan, Namibia Particle size and X-ray diffraction data for surficial samples collected on Etosha Pan, Namibia
This data release provides particle-size and X-ray diffraction (XRD) data of sediment samples collected from dust emission "hot-spots" at Etosha Pan, Namibia. The dataset supports the investigation of the mineralogical, hydrological, and climatic controls on atmospheric dust emissions from ephemeral lake beds, which are globally significant sources of mineral dust aerosols. The particle...
Data Release for Geologic Framework and Hydrogeology of the Rico Rico and Nogales 7.5' quadrangles, Upper Santa Cruz basin, Arizona, with 3-Dimensional hydrogeologic model Data Release for Geologic Framework and Hydrogeology of the Rico Rico and Nogales 7.5' quadrangles, Upper Santa Cruz basin, Arizona, with 3-Dimensional hydrogeologic model
Rapid population growth and declining annual recharge to aquifers in the upper Santa Cruz basin area of southern Arizona, has increased the demand for additional groundwater resources. This demand is predicted to escalate in the future due to higher temperatures, longer droughts, less aquifer recharge, and decreased river and stream base flow. We conducted geologic studies to help...
Model archive and data for water budget components in Minnesota simulated with the Soil-Water-Balance model for past (1981-2022) and future (2040-2059 and 2080-2099) periods Model archive and data for water budget components in Minnesota simulated with the Soil-Water-Balance model for past (1981-2022) and future (2040-2059 and 2080-2099) periods
This data release contains a model archive, ancillary data, and outputs for an application of the Soil-Water-Balance (SWB) model code (version 2, Westenbroek and others, 2018) to simulate water budget components at a 1-kilometer resolution for the state of Minnesota. The SWB model was calibrated to streamflow and actual evapotranspiration observations in 71 watersheds for 2000 - 2022...
Data on pronghorn energy expenditure in response to energy development and reclamation scenarios, southeastern New Mexico Data on pronghorn energy expenditure in response to energy development and reclamation scenarios, southeastern New Mexico
Raster data depicting estimated pronghorn (Antilocapra americana) energy expenditure required to move from each cardinal direction through the landscape under different scenarios of human impact: wind energy development (turbines), oil and gas development, no development, and oil and gas reclamation scenarios.
Planktic foraminifer occurrence data from the coastal plain of Virginia and North Carolina Planktic foraminifer occurrence data from the coastal plain of Virginia and North Carolina
Presence-absence data for planktic foraminifera from selected samples.
Microbial Source Tracking Data for Human and Canine Fecal Markers Collected in Houlton, Maine, June 2026 Microbial Source Tracking Data for Human and Canine Fecal Markers Collected in Houlton, Maine, June 2026
The U.S. Geological Survey, in collaboration with the Houlton Band of Maliseet Indians (HBMI), conducted a pilot microbial source tracking (MST) study to investigate sources of fecal indicator bacteria in the Meduxnekeag River watershed near Houlton, Maine. HBMI staff collected surface water samples from three sites in June 2026. Samples were analyzed using quantitative polymerase chain...
Time-lapse Photographs of Edge of Field site near Findlay, OH 2017–2020 Time-lapse Photographs of Edge of Field site near Findlay, OH 2017–2020
This data release contains time-stamped photographs collected by U.S. Geological Survey (USGS) cameras deployed at an agricultural edge-of-field study site in the Eagle Creek watershed near Findlay, Ohio. The photographs were captured as part of a long-term (2012–20) investigation conducted by the USGS in cooperation with the Great Lakes Restoration Initiative and the U.S. Department of
Advective and diffusive snowpack carbon dioxide fluxes from 2009-2016 at GLEES, Wyoming Advective and diffusive snowpack carbon dioxide fluxes from 2009-2016 at GLEES, Wyoming
Hourly carbon dioxide (CO2) measurements from four locations of snowpack profiles with vertical spacing of 20 cm over seven winters (2010-2016) at the Glacier Lakes Ecosystem Experiments Site (GLEES) in southern Wyoming. All supporting data on snowpack properties (mostly modeled) are included to calculate hourly snowpack CO2 fluxes from raw data. In addition, turbulence from the adjacent...
