Data

The U.S. Geological Survey St. Petersburg Coastal and Marine Science Center’s (USGS SPCMSC) Core Archive in St. Petersburg, FL contains a collection of coral-reef cores collected from throughout the Florida Keys reef tract (FKRT; Fig. 1). In a previous study (Toth and Stathakopoulos, 2019), USGS researchers analyzed the upper, Holocene (~11,700 years ago to present) sections of those...

These lidar point clouds and images cover, in high detail, the terrain at Great Sippewissett Marsh, Cape Cod, MA on November 2nd, 2022. USGS researchers tested different sensors that collected lidar and images for photogrammetry point cloud data using Uncrewed Aerial Systems (UAS) to look at differences in coverage and elevation accuracy. The lidar data were acquired with a YellowScan...

Data release contains peak-flow frequency analyses for selected streamgages in North Dakota, along with information documenting the input data and specifications for the analyses. The analyses were performed using the methods described by Siefken and others (2025). The analyses are presented by delineated basins in associated child items.

Monthly actual ET (ETa) data estimated for the growing season (April - October) at 30-meter resolution with the Operational Simplified Surface Energy Balance (SSEBop) model (version 2.6) using satellite imagery obtained from Landsat 4, 5, 7, 8, and 9, and reference evapotranspiration obtained from the North America Land Data Assimilation 2 (NLDAS2) product for the Milk River basin, from...

Data from a Nevada telemetry study extending 1997-2006 research on historical mercury contamination on snowy egrets (Egretta thula) up to ~ 20 days of age.

This dataset contains environmental DNA (eDNA) and visual encounter survey (VES) data collected between 2019 and 2022 in Colorado canyonlands. eDNA data (field, extraction, and qPCR) is for three target species: American bullfrog, northern leopard frog, and Great Basin spadefoot. VES data is for six target species: American bullfrog, northern leopard frog, Great Basin spadefoot, red...

Data includes functional group cover of exotic annual grasses and deep rooted perennial grasses within the first five years after the 2015 Soda wildfire across different post-fire restoration treatments. Additional landscape and restoration treatment covariates hypothesized to influence post-fire invasive annual grass and perennial grass cover are included.

Data release contains peak-flow frequency analyses for selected streamgages in Montana, North Dakota, South Dakota, and Wyoming, along with information documenting the input data and specifications for the analyses. The analyses were performed using the methods described by Siefken and others (2025).

This data release contains computed tomography (CT) scans, photographs, geochemistry, grain-size and total carbon analysis, X-ray fluorescence (XRF) scans, X-ray diffraction (XRD), magnetic susceptibility, and gamma-ray bulk density data of gravity cores, push cores, and sediment subsamples from those cores collected in 2022 from the Escanaba Trough vent field, Gorda Ridge, in the...

The U.S. Geological Survey evaluated the stability of water-sample chemical analysis of nutrient, alkalinity, and acid neutralizing capacity constituents with respect to the duration between sample collection and laboratory analysis, also known as sample holding times. Included in this data release are results used to evaluate the stability of the chemical properties alkalinity (as...

This U.S. Geological Survey (USGS) data release accompanies planned publication ‘New constraints on location and timing of the Great Lakes tectonic zone, central Upper Peninsula, Michigan, USA. The data release includes laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) U-Pb zircon data and/or U-Pb apatite data for two samples from the Upper Peninsula, Michigan, USA...

This dataset contains site information and results of flood-frequency analysis for 422 streamflow gaging stations (streamgages) operated by the U.S. Geological Survey (USGS) in parts of the Upper Mississippi and Souris-Red-Rainy basins and surrounding areas in the United States. Annual peak-flow data from the 1844 - 2013 water years were used in the study (U.S. Geological Survey, 2024)...
