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.

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...
