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.

Inverse Model Data for: Salinity trends in a groundwater system supplemented by 50 years of imported Colorado River water Inverse Model Data for: Salinity trends in a groundwater system supplemented by 50 years of imported Colorado River water
Data provided here describe the contribution of up to 7 different water sources to the major ion geochemistry of U.S. Geological Survey (USGS) and California State Water Resources Control Board Division of Drinking Water (CA-DDW) groundwater samples within the Indio Subbasin of the Coachella Valley, California. The Inverse Geochemical Modeling was performed in the USGS's PHREEQC ver. 3...
Questions and responses to USGS-wide poll on quality assurance practices for timeseries data, 2021 Questions and responses to USGS-wide poll on quality assurance practices for timeseries data, 2021
This data record contains questions and responses to a USGS-wide survey conducted to identify issues and needs associated with quality assurance and quality control (QA/QC) of USGS timeseries data streams. This research was funded by the USGS Community for Data Integration as part of a project titled “From reactive- to condition-based maintenance: Artificial intelligence for anomaly...
Microbial Populations in PFHxSAm (perfluorohexane sulfonamido propyl amine) Biodegradation Microcosms Microbial Populations in PFHxSAm (perfluorohexane sulfonamido propyl amine) Biodegradation Microcosms
Water resources around the world are contaminated with per- and polyfluoroalkyl substances (PFAS) due to releases from point sources on military installations, fire training centers, and chemical manufacturing sites. Non-point sources have also been identified including wastewater effluent, landfills, and biosolids application. PFAS are a major concern to myriad stakeholders as some are...
Vegetation survey of southwest Florida for use in assessment of the Picayune Strand Restoration Project effects Vegetation survey of southwest Florida for use in assessment of the Picayune Strand Restoration Project effects
This release consists of vegetation data collected across an environmental gradient at Ten Thousand Islands National Wildlife Refuge (TTI NWR) near Naples, Florida, USA. The refuge is within the impact area of the Picayune Strand Restoration Project (PSRP), a large-scale hydrologic restoration project in southwest Florida that was authorized by the U.S. Congress in 2007. Vegetation...
Molecular and distributional data used to investigate misidentifications, population genetic diversity, and spatiotemporal trends in distribution for Pleurobema riddellii to help guide ESA listing decisions Molecular and distributional data used to investigate misidentifications, population genetic diversity, and spatiotemporal trends in distribution for Pleurobema riddellii to help guide ESA listing decisions
We provide genetic and distribution data for the Louisiana Pigtoe, Pleorubema riddellii, to guide decisions related to federal protection for the species under the U.S. Endangered Species Act. Our final dataset includes 125 COI sequences generated as part of our study representing P. riddellii from eight North American river basins. This includes the COI sequence we generated from a...
Capture Data and SNP Genotypes to Evaluate Subspecies Range Boundaries of the Bell’s vireo (Vireo bellii pusillus and V. b. arizonae) (2010-2022) Capture Data and SNP Genotypes to Evaluate Subspecies Range Boundaries of the Bell’s vireo (Vireo bellii pusillus and V. b. arizonae) (2010-2022)
Genetic samples in the form of a small blood sample were collected from 263 Bell's vireos (Vireo bellii) in drainages throughout southern and central California, Arizona, southern Nevada, and southwestern Utah. We used population genomic techniques to delineate the range limit between the Least Bell's Vireo (V. b. pusillus) and its conspecific geographical neighbor, the Arizona Bell's...
