All Data

Data described herein was collected by USGS personnel and the project funded by USGS. Northern snakehead specimens were collected from the Potomac River and its tributaries by regional natural resource management agencies in the course of their field investigations working with this priority invasive aquatic species. Specimens were provided to USGS for the purpose of conducting health...

A three-dimensional, GSFLOW model was developed to simulate and quantify the hydrologic system of the Yucaipa subbasin. The model was calibrated to conditions from 1970 to 2014, the period for which data are most complete and reliable. The model was used to (1) quantify the effects of historical and potential water-resource development induced by climate changes and human-related...

The U.S. Geological Survey (USGS), in cooperation with the Kootenai Tribe of Idaho, used streamflow measurements at 14 partial-record sites and related them to nearby USGS real-time streamgages (index sites) to provide daily mean streamflow values at ungaged (partial-record) sites. Daily mean streamflow was estimated by developing a regression relationship between streamflow at each...

Surface electrical resistivity tomography (ERT), electromagnetic induction (EMI), and self-potential (SP) data were acquired March 9 - 20, 2018 by the U.S. Geological Survey, in collaboration with the U.S. Army Corps of Engineers, at the Jim Woodruff Lock and Dam near Chattahoochee, Florida. Eleven ERT profiles were acquired along the right (west) abutment, and immediately downstream, of...

This data set describes nuclear microsatellite genotypes derived from six autosomal loci (AgCA222, Age7.1JT, BV13, BV20, NVH206, NVH195-2) in Cooper's Hawks. Samples originated from blood samples collected from live trapped birds.

These morphometric data are in two tables from surfbirds (adults and chicks) captured at two locations in southcentral Alaska, 1997-1999.

This sampling frame is a set of grid-based, finite-area frames spanning the offshore areas surrounding Canada, the United States, and Mexico, and is intended for use with the North American Bat Monitoring Program (NABat). NABat is a continental collaboration including state and provincial, federal, and local agencies intended to standardize the collection and storage of bat data. Alaskan...

This data release identifies 555 Hydro-Climatic Data Network (HCDN) streamgages in the conterminous United States during the period 1981-2019 which were grouped according to similarity in their temporal patterns of monthly streamflow.

This dataset contains taxonomic and biovolume data for phytoplankton sampled from Detroit Lake, OR, in August, 2019, and August, 2020. Taxonomy is reported to the lowest possible taxonomic level along with total and percent biovolume. Surface grab samples for phytoplankton enumeration were collected with a van Dorn type sampler and then transferred into a clearn polycarbonate churn...

This dataset contains locations acquired from GPS-tagged Brown Pelicans in the South Atlantic Bight. Locations correspond to the movements of pelicans tracked for greater than 1 reproductive attempt, and include only locations from May - July of each year, with the goal of identifying likely nest locations using GPS data.

The U.S. Geological Survey (USGS), in cooperation with the Chester County Water Resources Authority (CCWRA), has collected discrete stream samples for analysis of suspended-sediment concentrations at seven gaging stations where near real-time continuous data on stream discharge, and turbidity have been collected since 2005. Historical regression equations to estimate suspended-sediment

The U.S. Geological Survey, in cooperation with Ashokan Watershed Stream Management Program, investigated the feasibility of bedload monitoring in the upper Esopus Creek watershed, Ulster and Greene Counties, New York (NY), from 2017 to 2020. Traditional bedload samples were collected at two locations: Birch Creek at Big Indian, NY, and Stony Clove at Jansen Rd at Lanesville, NY. Active...
