All Data

This digital data release contains spatial datasets of bedrock geology, volcanic ash bed locations, test hole locations, bedrock outcrops, and structure contours of the top of bedrock and the base of the Ogallala Group from a previously published map (Souders, 2000). The GeologicMap feature dataset contains separate feature classes for the Ogallala Group map unit (ContactsAndFaults and

The United States Documented Unplugged Orphaned Oil and Gas Well (DOW) dataset contains 117,672 wells in 27 states. The definition of an orphaned oil or gas well varies across data sources; the dataset includes oil or gas wells where the state indicates that the well is an unplugged orphan, or the following criteria are met: 1) no production for an average of 12 months (6 to 24 months...

The following data release contains coordinates for suspected historical spawning locations of lake whitefish (Coregonus clupeaformis) and cisco (Coregonus artedi) across the Lake Ontario basin, including the Niagara River and St. Lawrence River. These data were gathered from published and unpublished sources cited in the Atlas of the Spawning and Nursery Areas of Great Lakes Fishes...

These data represent an annotated training data for machine learned life history classification of the daily activity of dabbling ducks (f. Anatidae sf. Anatinae) using hourly GPS data. Each row of data represents a single GPS location for one of 5 species of dabbling duck. Note: the machine learned model was developed to be general across sf. Anatinae and does not include specific...

Desert spring wetlands host many endemic species that require aquatic habitat and are isolated by the surrounding xeric terrestrial habitat. The Dixie Valley Toad (Anaxyrus williamsi) is a recently described anuran species endemic to desert spring wetlands in the Dixie Valley, Churchill County, Nevada, USA. Given this species was only recently recognized as distinct from Anaxyrus boreas...

This data release presents a peak-flow frequency analysis (Eash and others, 2013) for U.S. Geological Survey streamgage 05465500 Iowa River at Wapello, Iowa. These methods are used to provide estimates of peak-flow quantiles corresponding to the 50-, 20-, 10-, 4-, 2-, 1-, 0.5-, and 0.2-percent annual exceedance probabilities (AEPs). Annual peak-flow data used in the peak-flow frequency...

This spreadsheet contains the results of open-bore auger samples collected by the U.S. Geological Survey in Maryland and Virginia for the Federal Highways Administration Turner-Fairbanks Highway Research Center. 19 sites were selected in 14 different locations across northern Virginia and southern Maryland by FBGC scientists to drill boreholes for the development of the TFHRC?s In-situ...

Sediment grab samples were collected from one onshore location and 32 undisturbed locations along the seafloor around Seven Mile Island, New Jersey (NJ) and Rockaway Peninsula, New York (NY). The sediment grab samples were collected in May and June of 2021 at locations within the area where multibeam bathymetry surveys were also conducted during the same trip. All sediment samples were...

Radiometric (gamma spectrometry) measurements were made during walking surveys in northern Maine using a GF Instruments Gamma Surveyor. These surveys involved recording measurement averages over 30-second intervals while holding the instrument approximately 1 meter above the ground. Locations were obtained via a handheld GPS. Data were collected over and in the vicinity of a radiometric...

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...

This United States Geological Survey (USGS) data release contains Darcy flux and mass flux of per- and polyfluoroalkyl substances (PFAS) measured using passive flux meters (PFMs) in monitoring wells associated with the Cannon Air Force Base (CAFB) in Clovis, New Mexico. The measurements were conducted by the USGS in cooperation with CAFB, the Air Force Civil Engineer Center, AECOM (an...

Dataset consists of 4, 7, 10, and 14-day responses of laboratory cultured mayflies (Neocloeon triangulifer) to sodium chloride exposure under different test condition scenarios. Responses were measured as mortality and growth (length). Water quality and analytical chemistry results associated with toxicity data are included. Experiments included 1) testing the influence of organism age...
