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.

North American Bat Monitoring Program Knitted Grid and Multi-scale Grid Covariates North American Bat Monitoring Program Knitted Grid and Multi-scale Grid Covariates
This data release contains spatial and tabular products that provide a multi-scale, continuous North American Bat Monitoring Program (NABat) master sample grid surface and a suite of ecologically-relevant covariates. This continuous surface, called the "knitted grid," is a combination of 5 kilometer (km), 10km, and 50km master sample grids for the Contiguous United States (CONUS), Alaska...
Assessment of Released Lake Sturgeon in the Genesee River, NY: 2003-2023 Assessment of Released Lake Sturgeon in the Genesee River, NY: 2003-2023
In 2003, a lake sturgeon reintroduction experiment was initiated in the Genesee River, NY. Young-of-year hatchery-reared lake sturgeon were released over multiple years. An assessment of the presence of lake sturgeon was done by systematic gill netting using monofilament nets. This data release is the lake sturgeon catch information collected during the systematic gill netting from 2003...
Stream Temperature and Thermal Sensitivity in Great Basin Region, 2011 - 2021 Stream Temperature and Thermal Sensitivity in Great Basin Region, 2011 - 2021
Warming climates, declining winter snowpacks, and increased periods of drought have contributed to warming stream temperatures and declining stream flows, impacting habitat availability for cold water species. Particularly in the northern Great Basin region available habitat may be restricted to headwaters, where cooler temperatures and reliable stream flows allow cold water species...
Microanalysis of samples from the Coles Hill Uranium Deposit, Pittsylvania County, Virginia, USA Microanalysis of samples from the Coles Hill Uranium Deposit, Pittsylvania County, Virginia, USA
These data are microanalyses of 22 polished thin sections that were examined using a scanning electron microscope (SEM) equipped with an energy dispersive spectrometer (EDS) to identify minerals and observe their relationships at high magnification. Samples are from uranium mineralized core drilled at the Coles Hill uranium deposit, Pittsylvania County, Virginia, and one sample of the...
Mercury Concentrations in Waters, Fish, Plants, and Sediments from Ghana, 2024 Mercury Concentrations in Waters, Fish, Plants, and Sediments from Ghana, 2024
This dataset presents mercury (Hg) and methylmercury (MeHg) concentration data in waters (surface river water and community drinking water), biota, plant, and sediments that were collected across eight communities along the Pra and Ankobra Rivers in Western Ghana. Water and sediment samples were collected in October 2024 from eight rivers along the Ankobra and Pra Rivers, two rivers...
Select elements of concern in surface water of three hydrologic basins (Delaware River, Illinois River and Upper Colorado River) — Data screening for the development of spatial and temporal models Select elements of concern in surface water of three hydrologic basins (Delaware River, Illinois River and Upper Colorado River) — Data screening for the development of spatial and temporal models
This data release is focused on the analysis of surface water concentration data associated with 12 elements of concern from three hydrologic basins. Data is analyzed with respect to: a) reporting limits, b) the extent of censored data, c) co-location with USGS real-time sensor data, and d) median concentrations at the catchment spatial scale. The Proxies Project (under the Water Quality...
