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.

Abiotic data collected in the St. Lawrence River and several tributaries in and adjacent to the Saint Regis Mohawk Tribe reservation in northern New York, 2004 Abiotic data collected in the St. Lawrence River and several tributaries in and adjacent to the Saint Regis Mohawk Tribe reservation in northern New York, 2004
This data set includes the sample site locations, site descriptions, and abiotic data used in the analyses reported in McKenna et al. 2008. The data represent selected abiotic conditions within the St. Lawrence and lower reaches of four US tributaries during 2004. Samples were collected from shallow, seinable areas (less than 1.5 m) of the St. Lawrence River, adjacent wetland channels...
Avian Point Transect Survey, Seward Peninsula, Alaska, 2012 Avian Point Transect Survey, Seward Peninsula, Alaska, 2012
This data package contains three tables: 1) avian point-transect survey data collected on the Seward Peninsula in 2012, 2) locations of all survey sites, and 3) an avian taxonomy table for reference.
High resolution and discrete temporal and spatial water-quality measurements in support of modeling mercury and methylmercury concentrations in surface waters of the Sacramento-San Joaquin River Delta High resolution and discrete temporal and spatial water-quality measurements in support of modeling mercury and methylmercury concentrations in surface waters of the Sacramento-San Joaquin River Delta
The Sacramento / San Joaquin River Delta (SSJRD) is contaminated with legacy mercury (Hg) from historical mining and mineral processing activities throughout the watershed, as well as from contemporary atmospheric and industrial inputs. The current project was designed for the purpose of developing high-resolution spatial and temporal models for estimating concentrations of mercury...
Microanalysis of samples collected from sandstone-hosted uranium and vanadium deposits in the Colorado Plateau: Utah, New Mexico and Colorado, USA Microanalysis of samples collected from sandstone-hosted uranium and vanadium deposits in the Colorado Plateau: Utah, New Mexico and Colorado, USA
These data are microanalyses of 91 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 the Triassic Chinle and Jurassic Morrison Formations and adjacent units, which are the main hosts for sandstone-hosted...
West Bay Sediment Diversion (MR-03): 2021 land-water classification West Bay Sediment Diversion (MR-03): 2021 land-water classification
The Louisiana State Legislature created the Coastal Wetlands Planning, Protection and Restoration Act (CWPPRA) in order to conserve, restore, create and enhance Louisiana's coastal wetlands. The wetland restoration plans developed pursuant to these acts specifically require an evaluation of the effectiveness of each coastal wetlands restoration project in achieving long-term solutions to...
Potomac River Watershed Accumulated Wastewater Ratios and Predicted Environmental Concentrations Potomac River Watershed Accumulated Wastewater Ratios and Predicted Environmental Concentrations
Treated effluent from wastewater treatment plants (WWTPs) contains contaminants not fully removed during the treatment process and that may pose environmental health risks when discharged to surface waters. This data release presents inputs for and results from a wastewater reuse model that used data compiled from several sources to calculate the following estimates for each non-tidal...
