Data Releases
The data collected and the techniques used by USGS scientists should conform to or reference national and international standards and protocols if they exist and when they are relevant and appropriate. For datasets of a given type, and if national or international metadata standards exist, the data are indexed with metadata that facilitates access and integration.

Bathymetric, water velocity, and water temperature data on the St. Croix River between St. Croix Falls, Wisconsin, and Stillwater, Minnesota, June 19-22, 2018 Bathymetric, water velocity, and water temperature data on the St. Croix River between St. Croix Falls, Wisconsin, and Stillwater, Minnesota, June 19-22, 2018
From June 19-22, 2018, bathymetric, water velocity, and water temperature data were collected on the St. Croix River between St. Croix Falls, Wisconsin, and Stillwater, Minnesota. These data were collected with a Teledyne RD Instruments RiverRay acoustic Doppler current profiler (ADCP) and georeferenced using a Trimble R10 Global Navigation Satellite System (GNSS) receiver connected to a...
Mores Creek Arm Bathymetric Survey, Lucky Peak Lake, Boise County, Idaho, May 11 - 13, 2021 Mores Creek Arm Bathymetric Survey, Lucky Peak Lake, Boise County, Idaho, May 11 - 13, 2021
In 2004, about 90 migrating elk drowned after attempting to cross thin ice on the Mores Creek arm of Lucky Peak Lake upstream of the Highway 21 bridge. To better understand the depths over a range of reservoir pool elevations in the Mores Creek Arm, the U.S. Geological Survey, in cooperation with the Lucky Peak Power Plant Project, conducted high-resolution multibeam echosounder (MBES)...
Nitrogen flux estimates in support of Chesapeake Bay Hypoxia and Anoxia forecasts, 1985-2021 Nitrogen flux estimates in support of Chesapeake Bay Hypoxia and Anoxia forecasts, 1985-2021
Data release includes the U.S. Geological Survey (USGS) estimate of spring nitrogen fluxes summed from nine tributaries to the Chesapeake Bay from 1985 to 2021. Data are presented as the sum from tributaries within the USGS River Input Monitoring (RIM) network identified by site numbers: 01491000, 01578310, 01594440, 01646580, 01668000, 01673000, 01674500, 02035000, 02041650. Periods of...
Terrestrial Tephra Spectral Library for the Visible-Near-Infrared and Mid-Infrared Spectral Regions (ver. 1.1, April 2024) Terrestrial Tephra Spectral Library for the Visible-Near-Infrared and Mid-Infrared Spectral Regions (ver. 1.1, April 2024)
Visible/near-infrared (VNIR) and mid-infrared (MIR) spectral library composed of twenty natural tephra samples from ten volcanic sources that span a range of compositions and components. The bulk, glass, and mineral phase compositions of each sample have been measured and VNIR and MIR spectra from four size fractions of each sample were collected. The VNIR spectral library has been...
Autonomous Underwater Vehicle Water-Quality, Bathymetric, and Sonar Measurements in the Black River near Elyria, Ohio, 2021 Autonomous Underwater Vehicle Water-Quality, Bathymetric, and Sonar Measurements in the Black River near Elyria, Ohio, 2021
These datasets were collected in support of the U.S. Environmental Protection Agency Region 5 at the Chemical Recovery Site in Elyria, Ohio, within the East Branch Black River on March 22, 2021. Water-quality and bathymetric data were measured and logged at 1-second intervals (AUV_CRS_Combined_032221.csv). Water-quality data collected during eight different missions were measured with a...
Luminescence, weather, and grain-size data from eastern Chuckwalla Valley, Riverside County, California Luminescence, weather, and grain-size data from eastern Chuckwalla Valley, Riverside County, California
This data release contains luminescence, weather, and sediment grain-size data from eastern Chuckwalla Valley, Riverside County, California. This study investigates sedimentary and geomorphic processes in eastern Chuckwalla Valley, Riverside County, California, a region of arid, basin-and-range terrain where extensive solar-energy development is planned. The objectives were to (1)...
