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...
