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.

Data release of geologic and geophysical maps of the Santa Maria and northern part of the Point Conception 30' x 60' quadrangles, California Data release of geologic and geophysical maps of the Santa Maria and northern part of the Point Conception 30' x 60' quadrangles, California
This dataset accompanies geologic map publication " Geologic and geophysical maps of the onshore parts of the Santa Maria and Point Conception 30' x 60' quadrangles, California "; U.S. Geological Survey Scientific Investigations Map 3473. Data presented here include the digital geologic map database, paleontological sample locations and descriptions, and point data sets from magnetic and...
Repeat measurements of bathymetry, streamflow velocity and sediment concentration made during a high flow experiment on the Colorado River in Grand Canyon, March 2008 Repeat measurements of bathymetry, streamflow velocity and sediment concentration made during a high flow experiment on the Colorado River in Grand Canyon, March 2008
The acoustic Doppler current profiler (ADCP) data were collected and compiled to characterize the velocity patterns in channel of the Colorado River and in an adjacent zone of laterally recirculating flow (eddy). Topographic/bathymetric digital elevation models (DEMs) were collected and compiled to characterize erosion and deposition in the Colorado River and in an adjacent zone of...
Stream Temperature of Desert Dace Habitat, Soldier Meadows, Black Rock Desert - High Rock Canyon Emigrant Trails National Conservation Area, Nevada, 2017-2020. Stream Temperature of Desert Dace Habitat, Soldier Meadows, Black Rock Desert - High Rock Canyon Emigrant Trails National Conservation Area, Nevada, 2017-2020.
This U.S. Geological Survey data release consists of a tabular dataset containing stream temperature data. Data were collected every 12-hours from 15 sites in Soldier Meadows, Black Rock Desert - High Rock Canyon Emigrant Trails National Conservation Area, Nevada. The sites were established by the Bureau of Land Management - Winnemucca District Office in 2017. The data release includes...
Parent and alkylated polycyclic aromatic hydrocarbons (PAHs) and per- and polyfluoroalkyl substances (PFAS) in north San Francisco Bay, Napa River, and Sonoma Creek in 2018 and 2019 Parent and alkylated polycyclic aromatic hydrocarbons (PAHs) and per- and polyfluoroalkyl substances (PFAS) in north San Francisco Bay, Napa River, and Sonoma Creek in 2018 and 2019
Sediment grain-size distributions, stable carbon isotope ratios (d13C), total carbon to total nitrogen ratios (C:N), short-lived radionuclides (Beryllium-7, Cesium-137, and Lead-210), concentrations of 76 parent and alkylated polycyclic aromatic hydrocarbons (PAHs) and concentrations of 33 per- and polyfluoroalkyl substances (PFAS) were measured in the northern reach of San Francisco Bay...
Drainage-basin characteristics associated with road and stream intersections in Montana Drainage-basin characteristics associated with road and stream intersections in Montana
This data release presents drainage-basin characteristics for 12,639 road and stream intersections in Montana. The drainage-basin characteristics presented include those computed by the Montana StreamStats application (McCarthy and others, 2016). Statistical analysis of the road and stream intersections was included in the report "Peak-Flow Variability, Peak-Flow Informational Needs, and
Table of Electron Probe Microanalyses of Native Copper and Sulfide Minerals from the White Pine Sediment-hosted Copper Deposit, Michigan Table of Electron Probe Microanalyses of Native Copper and Sulfide Minerals from the White Pine Sediment-hosted Copper Deposit, Michigan
This data release provides electron microprobe geochemical data that was collected as part of a scoping study to evaluate whether unconventional critical element resources may be associated with sediment-hosted copper systems in the Midcontinent Rift. We report abundances of trace elements in native copper and sulfide minerals in 12 thin sections from samples of the Mesoproterozoic lower...
