Data Releases

Airborne electromagnetic (EM) and magnetic survey data were collected by GeoTerrex Ltd. in the Upper San Pedro Basin and Fort Huachuca, Arizona in 1997 and 1999. EM data were collected using a time-domain GEOTEM system towed behind a fixed-wing aircraft with 30Hz cycle rate, 696,000 Am2 dipole moment, and 4 ms pulse width. Magnetic data were collected using a CS-2 cesium vapor...

These data contain located day-roosts for the northern long-eared bat (Myotis septentrionalis) at the North River Game Land, North Carolina in May and June of 2019. Data contained include individual bat tracked, date day-roost was found, day-roost unique ID, geographic coordinates of day-roost, tree species of day-roost, diameter breast height (cm) of day-roost, day-roost decay-stage...

Aerial imagery was collected with an uncrewed aerial system (UAS) and ground control points were used to construct a digital elevation model (DEM) and orthomosaic image using Structure-from-motion (SfM) photogrammetry for the Zuni Salt Lake in west-central New Mexico. The DEM and bathymetry survey points were combined to estimate lake water volume as a function of lake stage in the U.S...

To support the development of more accurate hurricane coastal impact models, we created a dataset containing an inventory of information sources of hard shoreline structures — including seawalls, groins, bulkheads, and breakwaters — for each U.S. state along the Gulf of America and Atlantic coasts. The shoreline structure inventory was developed initially from internet searches of open...

The U.S. Army Engineer Research and Development Center, in collaboration with the U.S. Geological Survey Wetland and Aquatic Research Center, collected hydrographic data to investigate sediment exchange between a back barrier marsh and open embayment through a tidal creek near Avalon, NJ, between July 2021 and August 2022. Data collected include time-series measurements of current...

This data release provides location information and lithologic intervals for boreholes compiled by the USGS between 2016 and 2020 for use during subsurface geologic mapping of the lower Colorado River corridor. The data provided include a spreadsheet of borehole information, that contains the well name, the information source, and positional information regarding the well location. A...

This data release contains in situ carbon and oxygen isotope analyses of calcite and dolomite collected via secondary ion mass spectrometry (SIMS), as well as major and trace element geochemical data, bulk mineral carbon and oxygen isotope data, and whole rock geochemistry for the samples included in this study. Also included are images from analyzed thin sections that show the sample...

Carolina northern flying squirrel presence and pseudo-absence points for eight high elevation North Carolina, Tennesse, and Virginia red spruce-Fraser fir forests. Data includes corresponding habitat variables (distance to spruce-fir forest, northern red oak forest, northern hardwood forest, open areas) and topographic variables (elevation, topographic exposure index, aspect), latitude...

This product is a georectified and tonally balanced mosaic of aerial photographs collected in 1930 by the U.S. Bureau of Reclamation along a portion of the floodplain of the Colorado River in Palo Verde Valley, Arizona and California. This dataset is a primary resource for the development of a surficial geologic map showing the floodplain and river channel characteristics along the...

Rare earth elements are critical mineral commodities typically extracted together as a group of 15 elements (lanthanides plus yttrium) from either 1) hard rock ores or 2) ion-adsorption clay deposits. The locations of hard rock mines targeting carbonatite and peralkaline magmatic rare earth deposits are well constrained and typically mined using conventional open-pit or underground...

Sulfur minerals, including sulfates (barite, celestine) and sulfides (pyrite, galena, chalcopyrite) are common throughout the Mountain Pass carbonatite. Changes in the sulfur isotope chemistry of sulfate and sulfide minerals record changes in temperature and oxygen fugacity in the system from which they precipitate, and early primary sulfate and/or sulfide minerals may record the primary...

This data release includes 3 child items with tracking data for caribou, a terrestrial mammal that ranges between the Alaska and Canada. Child Item 1: "GPS Tracking Data for Caribou (Rangifer tarandus granti) from the Denali Herd, Alaska, 2010-2018" Child Item 2: "GPS Tracking Data for Caribou (Rangifer tarandus granti) from the Fortymile Herd, Alaska, 1998-1999" Child Item 3: "GPS...
