Estimated annual recharge to the Edwards aquifer in the San Antonio area, by stream basin or ungaged area, 19342015.
The Edwards aquifer in south central Texas is one of the most permeable and productive aquifers in the United States and is the major source of public water supply for Bexar, Comal, Hays, Medina, and Uvalde Counties. The Edwards aquifer also supplies large quantities of water to agriculture, business, and industry in the region. The major artesian springs of the Edwards aquifer provide water for r
Multibeam bathymetry and acoustic backscatter data collected in 2016 for Lake Crescent, Olympic National Park, Washington
In February 2016 the U.S. Geological Survey, Pacific Coastal and Marine Science Center in cooperation with North Carolina State University and the National Park Service collected multibeam bathymetry and acoustic backscatter data in Lake Crescent located in Olympic National Park, Washington. These data were collected to support geologic hazard studies within the lake including mapping submarine la
Hawaii Land Cover and Habitat Status
These two raster data layers depict the land cover and degree of human disturbance to plant communities on the seven main Hawaiian Islands, and were developed as part of a comprehensive USGS assessment of carbon sequestration potential by natural ecosystems in the State of Hawaii.
Water-quality data for the South Atlantic Water Science Center (NWISWeb)
Chemical, physical, and biological properties of water, sediment, and tissue samples from Georgia, South Carolina, and North Carolina. Water-quality data are collected as either discrete field measurements or as continuous time-series data from automated recorders.

USGS Measurements of Dissolved and Particulate Material Selenium in Lake Koocanusa in the vicinity of Libby Dam (MT), 2015-2016
The U.S. Geological Survey is studying Lake Koocanusa, a border reservoir between British Columbia in Canada and Montana, in collaboration with the Montana Department of Environmental Quality and the U.S. Environmental Protection Agency (Region 8). This work is part of a multi-agency project to apply an ecosystem-scale selenium modeling methodology (Presser and Luoma, 2010) to the lake to support
Transcriptional response to West Nile virus infection in the zebra finch (Taeniopygia guttata), a songbird model for immune function: Data
The data set contains paired-end, 100 nucleotide long RNA sequencing reads for each sample. Raw sequencing reads ranged from 18-30million reads per sample. Quality trimmed reads were mapped to the Zebra Finch reference genome with an average of 79.0-80.8% mapping rate, corresponding to 18,618 Ensembl gene IDs. Of these, 14,114 genes averaged at least 5 mapped reads across all samples and were util
Data Documenting the U.S. Geological Survey Peak-Flow File Data Verification Project, 2008-16
These data provide a public summary of the changes made to the U.S. Geological Survey peak-flow file since formal Nation-wide checking began in 2008. Coverage includes peak-flow sites in the United States and territories.
Real time precipitation data for Georgia, North Carolina, and South Carolina (NWISWeb)
Data from rain gages that provide real-time data are relayed to the USGS and are transmitted from each station at intervals of 1 to 8 hours. Real-time data available on these web pages are provisional data that have not been reviewed or edited.

Benthos and Plankton data for Waukegan Harbor Area of Concern, Illinois, and Burns Harbor-Port of Indiana Non-Area of Concern, Indiana, in 2015
During two seasonal sampling events in spring (June) and fall (August) of 2015, the U.S. Geological Survey, in cooperation with the Illinois Department of Natural Resources and the U.S. Environmental Protection Agency, collected benthos (benthic invertebrates) and plankton (zooplankton and phytoplankton) at three sites each in the Waukegan Harbor Area of Concern (AOC) in Illinois and in Burns Harb
