Bathymetry and acoustic backscatter data of the Sacramento River, from the Feather River to Knights Landing, California in February, 2011

On February 1, 2011, the USGS Pacific Coastal and Marine Science Center (PCMSC) team carried out a project using interferometric sidescan sonar to characterize the riverbed and channel banks of a 12 mile reach of the Sacramento River near the town of Knights Landing, California (River Mile 79 through River Mile 91). The project was developed in coordination with David Smith, Engineering Research a

Evapotranspiration units and potential areas of groundwater discharge delineated July 2024, 2009 in the upper Humboldt River Basin, northeastern Nevada

This USGS data release represents the evapotranspiration units and potential areas of groundwater discharge geospatial data from the following publication: Plume, R.W., and Smith, J.L., 2013, Properties of basin-fill deposits, a 19712000 water budget, and surface-water-groundwater interactions in the upper Humboldt River basin, northeastern Nevada: U.S. Geological Survey Scientific Investigatio

New York Peak Flows

Locations (depicted as orange dots) in New York State where the New York Water Science Center has records of maximum recorded stages and discharges.

Computer automated frog vocalization results from Picayune Strand State Forest, Florida 2011-2012

This dataset includes the results of a computer automated anuran vocalization recognition analysis of audio recordings made at Picayune Strand State Forest in 2011 and 2012. The audio files were scanned for 11 species of frogs and toads using the commercially available software program Song Scope (ver. 4.1.3). All detections by the software are listed here along with a "result" field which indicat

Human-associated indicator bacteria and human specific virus loads, sample volumes, and drainage areas for six Menomonee River Watershed sampling locations

Human-associated indicator bacteria and human specific viruses in the Menomonee River watershed in Milwaukee, WI were investigated from April 2009 to March 2011 at six sampling locations within the watershed. We used concentration and water volume data from runoff-event and low-flow periods to compute loads for each sample collected, and subsequently used those loads, and drainage area from each

Surface-water data for the South Atlantic Water Science Center (NWISWeb)

Real-time, daily, peak-flow, field measurements, and statistics of current and historical data that describe stream levels, streamflow (discharge), reservoir and lake levels, surface-water quality, and rainfall in Georgia, South Carolina, and North Carolina.

USGS_Delmarva_SedTexture_Geomorph: Sediment Texture and Geomorphology of the Sea Floor from Fenwick Island, Maryland to Fisherman's Island, Virginia (polygon shapefile, Geographic, WGS84)

These data are a qualitatively derived interpretive polygon shapefile defining surficial sediment type and distribution, and geomorphology, for nearly 1,400 square kilometers of sea floor on the inner-continental shelf from Fenwick Island, Maryland to Fishermans Island, Virginia, USA. These data are classified according to Barnhardt and others (1998) bottom-type classification system, which was mo

Data from coastal circulation and water-column properties in the National Park of American Samoa, February-July 2015

In 2015, U.S. Geological Survey (USGS) and U.S. National Park Service (NPS) researchers began a collaborative study to determine coastal circulation patterns and water-column properties along north-central Tutuila, in an area focused on NPSAs Tutuila Unit and its coral reef ecosystem. The continuous measurements of waves, currents, tides, and water-column properties (temperature and salinity) from

Water Quality Watch New York

Water Quality Watch provides access to real time water-quality data collected in surface waters throughout the United States as part of the USGS mission to describe water resources. Measurements include streamflow (through WaterWatch) water temperature, specific conductance, pH, dissolved oxygen, turbidity, and nitrate. 

Groundwater data for the South Atlantic Water Science Center (NWISWeb)

Data from wells, springs, test holes, tunnels, drains, and excavations in Georgia, South Carolina, and North Carolina; well location data includes information such as latitude and longitude, well depth, and aquifer. Current and historical observations, and daily data are offered.

Phytoplankton Species Composition, Abundance and Cell Size in San Francisco Bay: Microscopic Analyses of USGS Samples Collected 1992-2014

This Data Release makes available measurements of phytoplankton species composition, abundance and cell size made on samples collected in San Francisco Bay (CA) from April 1992 through March 2014. Phytoplankton samples were collected at 31 stations along a 145-km transect where the variability of salinity, temperature, turbidity and nutrient concentrations reflected a broad range of environmental

Digital elevation models of the State Route 530 landslide near Oso, Washington, July 2014 to July 2015

Digital elevation models of the SR530 Landslide, created using structure from motion photogrammetry. These surveys were performed at irregular intervals between July 1, 2014 and July 7, 2015. Due to the photogrammetric methods used to collect these surveys, there may be substantial artifacts near the edges of the surveys, in areas of vegetation, or over extents of bare water, and should be used wi
