The USGS Northern Rocky Mountain Science Center, in collaboration with the Department of Earth Sciences, Montana State University, collected Propagation Saw Tests (PSTs) on a slope near Beehive Basin, Montana, before and after the snowpack collapsed unexpectedly. We also analyzed videos of these tests to measure weak layer collapse heights. A PST is a snowpack test that estimates crack...

Stable isotope dataset from fauna, particulate organic matter (POM) and sediments used to construct isotopic niches to compare trophic relationships in mesophotic coral habitats across the Gulf of America.

These data were compiled to support systematic analysis of ecological state and transition dynamics at the landscape scale in the Upper Colorado River Basin using published Natural Resources Conservation Service (NRCS) Ecological Site Descriptions (ESDs). Ecological sites are soil and climate-based classes of land that differ in potential plant communities and responses to disturbance...

Results of predicted groundwater levels and related spatial diagnostics, produced by an applied prediction-modeling statistical-research workflow, are provided as multi-banded GeoTIFF rasters for two custom bundles (classifications) of local aquifer codes for many thousands of wells in the hydrogeologically complex Chicot aquifer system, southwestern Louisiana. The modeling workflow was...

This data release provides gridded predictions of “typical” well depth for the hydrogeologically complex Chicot aquifer system, southwestern Louisiana. These predictions were made using an applied statistical prediction modeling workflow named welldepmod_make.R (Asquith and Lindaman, 2025) to estimate groundwater well depths for two custom bundles (classifications) of local aquifer codes...

The U.S. Geological Survey-Great Lakes Science Center (USGS-GLSC) began annual bottom trawl surveys of the Lake Huron prey fish community in 1976 to provide prey fish data for the Lake Huron fishery management community. The first full bottom trawl survey covering Michigan waters of Lake Huron was conducted in 1976. An integrated acoustics-midwater trawl survey was started by the USGS...

This dataset contains step lengths of individual loggerhead sea turtles tracked during their migration in the Gulf of America from 2008 to 2015. Information contained in the dataset includes platform terminal transmitter (PTT) number (a unique identifier for each turtle), the length of each move, year, location in either neritic or oceanic waters, date, longitude, latitude, difference...

These datasets contain information on the probabilities of storm-induced erosion (collision, overwash and inundation) on sandy beaches along the U.S. Gulf coast of Texas, Louisiana, Mississippi, and Alabama during hurricane impact conditions of Hurricanes Laura and Delta in 2020. The analysis is based on a storm-impact scaling model that uses observations of dune morphology combined with

U. S. Geological Survey (USGS) scientists completed a data collection campaign from the 3rd of June to the 22nd of July in 2024, using various methods to record geomorphic and habitat indicators throughout 30 streams in the Maryland-Washington, DC-Virginia Developed Piedmont region. Field methods included GNSS surveys, gravelometer-based pebble count readings, visual assessments, and...

This data release contains summary metrics describing stream stage, stream water temperature, and short-term climate conditions (daily precipitation and air temperature) for 30 streams spanning gradients of forest and agricultural land uses and the implementation of agricultural best management practices in a mixed agricultural region in Pennsylvania and Maryland, USA. This setting is...

This Data Release serves as a companion to the USGS Scientific Investigations Report titled "Streamflow Characterization and Effects of Highway Construction on Water-quality and Channel Morphology of the French Broad River near Highway Construction in Buncombe and Henderson Counties, North Carolina, 2019-2022" (Stillwell and others, 2026). Two tables of data are included in this Data...

This data release includes information on data from 72 streamflow or surface-water presence datasets in the Conterminous United States. It includes location, dataset, parent dataset or publication, site identification (if available), start year, end year, number of years, number of days, frequency of data collection, Strahler stream order, and headwater status.
