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.

Topographic and bathymetric data, sediment samples, structure from motion imagery, and reference mark data collected at Marconi Beach, Wellfleet in winter 2021, U.S Geological Survey Field Activity 2021-022-FA Topographic and bathymetric data, sediment samples, structure from motion imagery, and reference mark data collected at Marconi Beach, Wellfleet in winter 2021, U.S Geological Survey Field Activity 2021-022-FA
The data in this publication map the beach and nearshore environment at Marconi Beach in Wellfleet, MA and provide regional context for the 2021 CoastCam installation that looks out at the coast shared by beachgoers, shorebirds, seals, and sharks. These data were collected as part of field activity 2021-022-FA and a collaboration with the National Park Service at Cape Cod National...
Data for "Weakening of Peridotite Sheared at Hydrothermal Conditions" Data for "Weakening of Peridotite Sheared at Hydrothermal Conditions"
This data release comprises three separate datasets and their accompanying metadata, in zip files. The data were acquired as part of a laboratory study of the response of ultramafic materials to shear at hydrothermal conditions. The principal dataset consists of the strength-displacement data from 28 friction experiments acquired on gouges prepared from peridotite rock samples and from...
Census counts of benthic foraminifera, environmental parameters (temperature, salinity, and oxygen concentration), and radiocarbon measurements from cores obtained under and near a whale-fall off western Vancouver Island, British Columbia, Canada Census counts of benthic foraminifera, environmental parameters (temperature, salinity, and oxygen concentration), and radiocarbon measurements from cores obtained under and near a whale-fall off western Vancouver Island, British Columbia, Canada
This data release provides census counts of benthic foraminifera (in percent for the total fauna and as raw counts for just the living specimens) as well as environmental parameters (temperature, salinity, and oxygen concentration) at the sampling sites, and radiocarbon measurements from selected push core samples obtained under and near a whale-fall off western Vancouver Island, British...
Temperature and invertebrate community composition at nearshore Great Lakes sites, 2013-2016 (ver. 2.0, April 2025) Temperature and invertebrate community composition at nearshore Great Lakes sites, 2013-2016 (ver. 2.0, April 2025)
Data on ambient water temperatures and invertebrate community composition from ~40 sites in the western basin of Lake Erie, Saginaw Bay (Lake Huron), Grand Traverse Bay (Lake Michigan) and Green Bay (Lake Michigan). These samples were collected as part of a study on spatial variation in ecosystem processes.
Data and Regression Models for Suspended Sediment, Total Nitrogen, and Total Phosphorus for School Branch at CR750N at Brownsburg, Indiana, June 23, 2015 to February 6, 2019 Data and Regression Models for Suspended Sediment, Total Nitrogen, and Total Phosphorus for School Branch at CR750N at Brownsburg, Indiana, June 23, 2015 to February 6, 2019
The primary data sets consist of continuous water-quality data (temperature, specific conductance, pH, dissolved oxygen, turbidity, nitrate plus nitrite, and streamflow) from in-situ equipment, and discrete water-quality samples (total nitrogen, total phosphorus, suspended sediment concentration, and suspended sediment sieve diameter) collected during site visits at the USGS streamgage...
GIS Data for Geology of the Payette National Forest and Vicinity, West-Central Idaho GIS Data for Geology of the Payette National Forest and Vicinity, West-Central Idaho
The data release for the geology of Payette National Forest and vicinity, west-central Idaho, is a Geologic Map Schema (GeMS)-compliant version that updates the GIS files for the geologic map published in U.S. Geological Survey (USGS) Professional Paper 1666 (Lund, 2004). The updated digital data present the attribute tables and geospatial features (points, lines and polygons) in the...
Geophysical Data Collected in the Des Moines River, Beaver Creek, and the Des Moines River Floodplain, Des Moines, Iowa, 2018 Geophysical Data Collected in the Des Moines River, Beaver Creek, and the Des Moines River Floodplain, Des Moines, Iowa, 2018
A suite of geophysical methods was used along the Des Moines River, Beaver Creek, and in the Des Moines River floodplain in Des Moines, Iowa to support the hydrogeologic characterization of the alluvial aquifer associated with the river. The aquifer consists of sands and gravels underlain by weathered shale bedrock. Groundwater from the aquifer along with surface water sources are used...
Laboratory Observations of Variable Size and Shape Particles: Artificial Sand and Oil Agglomerates Laboratory Observations of Variable Size and Shape Particles: Artificial Sand and Oil Agglomerates
Following marine oil spills, weathered oil can mix with sediment in the surf zone and settle to the seafloor to form mats up to hundreds of meters long. Wave action fragments these mats into 1 to 10 cm diameter sand and oil agglomerates (SOAs). SOAs can persist for years, becoming buried in or exhumed from the seafloor and/or transported cross-shore and alongshore (Dalyander and others...
Water Availability Tool for Environmental Resources for the Commonwealth of Kentucky updated for 2019 Water Availability Tool for Environmental Resources for the Commonwealth of Kentucky updated for 2019
In 2009, the Kentucky Water Science Center completed the Water Availability Tool for Environmental Resources (WATER-KY), which provided the ability to simulate streamflow for the period 1980-2000. This model integrated TOPMODEL (Beven and Kirkby, 1979) for pervious portions of the landscape with simulation of flow generated from impervious surfaces (USDA, 1986). Associated products...
Geochemical data for waters, rocks, sediments and biofilms from Rio Tinto, Spain Geochemical data for waters, rocks, sediments and biofilms from Rio Tinto, Spain
Rio Tinto, Spain, is an example of a fluvial system strongly influenced by acid rock and acid mine drainage. During the spring of 2018 and 2019, samples of stream waters and mine waters, biofilms, sediments and rocks, were collected in the field by Aubrey Zerkle. These samples were analyzed for comprehensive geochemistry, including Cr isotope geochemistry, anions and cations...
Debris-flow and Flood Video Files, Chalk Cliffs, Colorado, USA, 2015 Debris-flow and Flood Video Files, Chalk Cliffs, Colorado, USA, 2015
Chalk Cliffs, located 8 miles southwest of Buena Vista, Colorado, is one of the most active debris-flow areas in the state (U.S. Geological Survey). Three stations were set up at Chalk Cliffs which are located sequentially along a channel draining the 0.3 km2 study area. These stations are equipped with rain gauges, laser distance meters, and data loggers to record rainfall and stage...
Data release for Evidence of glacial activity during MIS 4 in the Rocky Mountains, Colorado, USA Data release for Evidence of glacial activity during MIS 4 in the Rocky Mountains, Colorado, USA
The Ziegler Reservoir fossil site near Snowmass Village, Colorado (USA) provides a rare opportunity to examine environmental conditions in the Rocky Mountains during marine isotope stage (MIS) 4 (71-57 ka). Although recognized as a global-scale cold event, MIS 4 is typically absent from Rocky Mountain glacial chronologies because the geologic evidence was either covered or destroyed...
