Data

Three complementary datasets are presented: seismic recordings; photogrammetric point clouds; and rebound hammer measurements. On 4-5 March 2020, U.S. Geological Survey simultaneously collected three-component seismic data from three sites within the Trona Pinnacles National Natural Landmark: the top of a "skinny" pinnacle; the top of a "stout" pinnacle; and at a "reference" site. The...

This data release contains sensor-based water-quality and discrete stable isotopes of water data collected along the Upper Colorado River. Data collection was made by the University of Colorado at Boulder, Colorado (CO), and the U.S. Geological Survey (USGS) in Lakewood, CO. The water-quality data were collected from an inflatable raft during 5 high flow and 3 low flow sampling campaigns...

These data were collected as part of the USGS Sierra Nevada Forest Dynamics Study. They include tree diameter and mortality data as well as tree species identification and plot measurements from 8 plots located in Sequoia National Park from 1984 to 2023.

The Barrier Island Comprehensive Monitoring (BICM) program was developed by Louisiana’s Coastal Protection and Restoration Authority (CPRA) and is implemented as a component of the System Wide Assessment and Monitoring Program (SWAMP). The program uses both historical data and contemporary data collections to assess and monitor changes in the aerial and subaqueous extent of islands...

Data include locations where shorthead redhorse (Moxostoma macrolepidotum) and silver redhorse (Moxostoma anisurum) were detected following tagging events in the Sandusky and Cuyahoga Rivers, Ohio, USA. Location data were obtained primarily through stationary acoustic receivers, with additional locations from radio towers and mobile acoustic and radio surveys in the Cuyahoga River. The...

Reported here are the geographic sampling information associated with the raw shotgun sequencing data of multiple families of Polychaeta samples collected from cold seep sites off the U.S. Atlantic margin as well as raw 18S amplicon sequencing data from sediment eDNA collected from Astoria Canyon seeps, located on the Cascadia margin, northeastern Pacific Ocean. Also included are GenBank...

These data are for a geochronologic study of Cretaceous Elkhorn Mountains Volcanics and several discrete satellite plutons adjacent to the Cretaceous Boulder batholith of western Montana. Zircon from the two volcanic units of the Elkhorn Mountains Volcanics and four samples of satellite plutons of the Boulder batholith were dated by sensitive high resolution ion microprobe (SHRIMP). When...

Recreational-grade sidescan sonar offers a rapid and cost-effective method for imaging benthic environments, and recent advances in image processing techniques have shown promise for producing automated, reproducible substrate maps from sonar imagery. To investigate potential suitability of substrates for lake sturgeon spawning habitat, the U.S. Geological Survey (USGS), in cooperation...

Vegetation structure and fuels data are essential for understanding fire behavior following management treatments such as mechanical thinning and prescribed burning. To evaluate these processes, 133 plots were established between July 17 and September 21, 2025 across national forests and parks in the Sierra Nevada. These plots consisted of treated and untreated areas for comparison...

These data were collected as part of the USGS Sierra Nevada Forest Dynamics Study. They include tree mortality data from 30 plots located along an elevational gradient in the Sierra Nevada of California from 1982 to 2019. Although the data were collected annually, for purposes of compatibility with a global analysis, they were abstracted to five-year census intervals.

This dataset contains offshore fault geometries for frontal thrust splay faults in the Cascadia Subduction Zone (CSZ) that were mapped and developed for use in 3D ground motion simulations (Dunham and others, 2025). There are a total of 6 thrust faults (A-F), three of the faults (A-C) were mapped by interpretation of seismic reflection data (Ledeczi and others, 2024; Lucas and others...

This data release contains output from a numerical snow simulation for a 166 kilometer (km) × 160 km model domain in the Qashqadaryo region of Uzbekistan. The simulation encompasses key watersheds within the region and uses SnowModel (Liston and Elder, 2006; Liston and others, 2020; Liston, 2020) to estimate the snow water resources and meteorology across the simulation domain. The...
