Data

This data release contains near-surface geophysical and hydrological datasets collected along a historic coal-mining impacted reach of Nanticoke Creek near Wilkes-Barre, Pennsylvania, which is completely dry at its terminus during baseflow conditions. The release includes specific conductance data from a series of sodium chloride tracer slug injection experiments conducted on June 11...

This dataset describes tissue samples derived from Phragmites leaves spanning a developmental gradient from the youngest fully-expanded leaves to senescing leaves, as well as freshly senesced and partially decomposed leaf litter. Sample information includes leaf category, broad and local scale environmental descriptors, the geographic name and location of collection sites, and National...

Samples for episodes 1–39 (2024-2025) of the 2024-ongoing episodic Halema‘uma‘u Kīlauea eruption were collected by the U.S. Geological Survey’s Hawaiian Volcano Observatory (HVO) field teams from within publicly closed areas of Hawai‘i Volcanoes National Park in cooperation with the National Park Service. This data release presents sample metadata, whole rock ED-XRF, whole rock WD-XRF...

This data release reports electron probe microanalysis (EPMA) and laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) data from glass grains in tephra from Hiʻonamoa Gulch, on the southeastern flank of Mauna Loa volcano, Island of Hawaiʻi. The samples were collected from an outcrop approximately two meters thick located at latitude 19.2995 and longitude -155.57744...

This data release contains sample information for Coregonus artedi, Coregonus hoyi, Coregonus kiyi, and Coregonus zenithicus collected from Lake Nipigon and the Laurentian Great Lakes that have been genotyped with restriction site-associated DNA sequencing (RAD-seq) for population genetic analysis. Sample information includes: the National Center for Biotechnology Institute BioProject...

This dataset includes fish population and habitat data collected in 2025 to support development of the upper Santa Ana River Habitat Conservation Plan for the Santa Ana Sucker (Catostomus santaanae) and the Arroyo Chub (Gila orcuttii) in the Santa Ana River, California.

This data release compiles multi-year temperature datasets from the Santa Ana River, including continuous temperature records collected by USGS, San Bernardino Valley Municipal Water District, and Riverside-Corona Resource Conservation District to support analyses of spatial and temporal thermal conditions.

Scale Specific Sinuosity (S3) attributes are generated for the global SWOT River Database (SWORD) stream reaches greater than 150 meters in length. The S3 and SWORD reach attributes are used in a Random Forest model, trained on 745 gage sites on SWORD measured reaches in North America with available USGS ADCP data. The model is used to predict a baseline Manning’s n resistance...

At present, 2026, USGS river bathymetry surveys in ScienceBase lack a consistent, standardized organizational structure which impedes discovery and use of these datasets. Standardization of USGS bathymetry surveys allows these data to be more easily identified, queried, and incorporated into any number of science applications across a range of spatial scales. This data release includes...

The files in this data release are those referenced in the journal article by Neely and others (2026) entitled “Assessment of antibiotic resistance genes in Caribbean corals, including those treated with amoxicillin.” They represent the raw fluorescence data and threshold cycle (Ct) data generated from quantitative polymerase chain reaction (qPCR) microarray runs using deoxyribonucleic...

The U.S. Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center (SPCMSC) conducted research to quantify bathymetric changes in the Northern Florida Keys from Triumph Reef to Pickles Reef during two time periods, 1934 to 2002 and 2002 to 2016, within a 234.2 square-kilometer area. USGS staff calculated changes in seafloor elevation for both time periods using historical

Annual and seasonal trends in nitrogen and phosphorus loads, mean concentrations (flow-weighted loads), mean yields (area-weighted loads), and possible related stresses on aquatic ecology were estimated for the period December 1999 through November 2020 for each of 261,247 individual stream reaches and 81,717 12-digit hydrologic units (HUC12s) in the conterminous United States (CONUS)...
