Data

During water years 2016–2023 (a water year is the period from October 1 to September 30 and is designated by the year in which it ends), the U.S. Geological Survey (USGS), in cooperation with the Illinois Environmental Protection Agency (Illinois EPA), operated continuous monitoring stations on eight of the major rivers in Illinois to better quantify nutrient and sediment loadings from...

Geochemical and mineralogical characterization data was collected for samples of the Greenhorn Formation taken from the USGS Portland 1 core, which is stored in the USGS Core Research Center (library number E099 https://my.usgs.gov/crcwc/core/report/11834). The data was integrated with sedimentological descriptions in a manuscript (Flaum and others, 2025) that includes revised...

The U.S. Geological Survey (USGS), in cooperation with the U.S. Department of Energy and Naval Reactors Facility (NRF), collected sediment samples along the Industrial Waste Ditch (IWD) located on the northern boundary of the NRF. Sediment samples were collected at various intervals downstream from the outfall at different positions within the ditch as well as dredge pile sediments...

These data were collected as part of a larger project to support Total Maximum Daily Load (TMDL) modeling in the Big Soos Creek basin. Water temperature, air temperature and sensor depth were collected from four sites in the Big Soos Creek basin; LITTLE SOOS CREEK BELOW LAKE YOUNGS NEAR KENT, WA (USGS site ID 12109400), JENKINS CREEK AT 188TH AVE SE NEAR KENT, WA (USGS site ID 12110300)...

The database for the Washington West 30- by 60-minute quadrangle covers an area of approximately 4,884 square kilometers (1,343 square miles) in and west of the Washington, D.C., metropolitan area. The eastern part of the area is highly urbanized, and more rural areas to the west are rapidly being developed. The area lies entirely within the Chesapeake Bay drainage basin and mostly...

Observations and subtle shifts of aquatic vegetation communities in Lake Erie have USGS researchers concerned about the potential for grass carp and other threats to alter these vegetation communities. Assessing submersed aquatic vegetation (SAV) may contribute to inform the long-term impacts of grass carp, common carp, eutrophication, wind fetch and sedimentation on SAV communities...

The U.S. Geological Survey (USGS) developed and calibrated a Water Quality Analysis Simulation Program (WASP) model (version 8.4) for the Barnegat Bay-Little Egg Harbor Estuary (hereafter referred to as 'the Estuary'), New Jersey. This model was externally coupled with a previously developed hydrodynamic model (Defne and Ganju, 2015 and 2018) to simulate dissolved oxygen, nutrient...

These data consist of the behavioral responses of Pacific and Yellow-billed Loons to helicopter overflights and ground-based human activity in disturbed vs. undisturbed areas, as well as nest success in the summers of 2016 and 2017 at two field camps in the Fish Creek watershed, NPR-A.

These data are high-resolution bathymetry (riverbed elevation) and depth-averaged velocities in comma-delimited table format, generated from hydrographic and velocimetric surveys near highway bridge structures over the Missouri River in Kansas City, Missouri, on August 8–9, 2023. Hydrographic data were collected using a high-resolution multibeam echosounder mapping system (MBMS), which...

This data release contains the boundaries of assessment units, assessment input data, and resulting fact sheet data tables for the assessment of undiscovered oil and gas resources in Oman. The assessment unit is the fundamental unit used in the National and Global Oil and Gas Assessment Project for the assessment of undiscovered oil and gas resources. The assessment unit is defined...

Note: This data release has been deprecated. A new version is currently in press. This data release includes downscaled climate inputs and hydrologic outputs from the Basin Characterization Model (BCM) version 8 (v8), described in Flint et al. (2021a), in a 30 by 30-meter spatial resolution at a monthly time step from water years 1896 to 2023 for the upper Feather River watershed. This...

Scientists from the U.S. Geological Survey St. Petersburg Coastal and Marine Science Center in St. Petersburg, Florida (USGS–SPCSMC), conducted a geophysical survey of the northern Chandeleur Islands, Louisiana during two survey legs: June 12-21 and July 31-August 11, 2023. During this study, multibeam bathymetry and sub-bottom geophysical data (Forde and others, 2024) were collected...
