Water-surface and groundwater-level elevations on and near Offutt Air Force Base, Nebraska, summer 2020 and spring 2021 Water-surface and groundwater-level elevations on and near Offutt Air Force Base, Nebraska, summer 2020 and spring 2021
This data set contains two sets of measured water-level data collected on and near Offutt Air Force Base near Bellevue, Nebraska. Surface-water and groundwater-level data were collected for two synoptic water-level surveys completed in late summer of 2020 and in spring 2021. The elevations of surface-water features were surveyed with a rover receiver using a real-time network (RTN)...
Southern Beaufort Sea Polar Bear Blood Based Analyte Data, 1983-2018 Southern Beaufort Sea Polar Bear Blood Based Analyte Data, 1983-2018
This dataset is one table with data collected and derived from polar bears sampled in Alaska's southern Beaufort Sea during 1983-2018. Collected data includes demographic and morphometric information. Derived data includes blood-based analyte values determined from whole blood and serum samples. Serum samples were analyzed on an Abaxis VS2 Biochemistry Analyzer and whole blood samples...
True color and multispectral imagery data collected by small unoccupied aircraft systems at the USGS National Crude Oil Spill Fate and Natural Attenuation Research Site, Bemidji, Minnesota, June 2018 True color and multispectral imagery data collected by small unoccupied aircraft systems at the USGS National Crude Oil Spill Fate and Natural Attenuation Research Site, Bemidji, Minnesota, June 2018
The U.S. Geological Survey (USGS) deployed multirotor small unoccupied aircraft systems (sUAS or drones) on June 21, 2018, to collect imagery data documenting site conditions at the USGS National Crude Oil Spill Fate and Natural Attenuation Research Site near Bemidji, Minnesota, USA. True color visible light images were collected across the general study area. Multispectral images in...
Geochemical data for stream water samples from streams around the Pogo Deposit and Black Mountain Au occurrences, Big Delta quadrangle, Alaska, 2021 Geochemical data for stream water samples from streams around the Pogo Deposit and Black Mountain Au occurrences, Big Delta quadrangle, Alaska, 2021
This data release is the result of a hydrogeochemical sampling campaign during summer 2021 to investigate whether high resolution geochemical analysis of waters for element chemistry can be used as an exploration tool for identifying gold-rich occurrences in parts of the Big Delta B-1 and B-2 quadrangles, within the Yukon-Tanana Upland region, Alaska. Historical USGS conventional stream...
Geophysical and core sample data collected in lakes and fjords of southcentral Alaska following the 2018 Anchorage earthquake (ver. 2.0, October 2023) Geophysical and core sample data collected in lakes and fjords of southcentral Alaska following the 2018 Anchorage earthquake (ver. 2.0, October 2023)
This dataset includes sub-bottom seismic and sediment core data collected during USGS field activities 2021-612-FA, 2020-625-FA, and 2020-615-FA. Sub-bottom data include Chirp seismic in SEG-Y format with associated navigation tracklines. Core data include photo and computed tomography (CT) scans, and various mineralogical, radiometric, and other sampling data. Users are advised to read...
Kinnickinnic River Geochemistry and Rapid Geomorphic Assessments, Waukesha County, Wisconsin Kinnickinnic River Geochemistry and Rapid Geomorphic Assessments, Waukesha County, Wisconsin
From September 2019 to October 2020 a stream sediment budget and sediment fingerprinting integrated study was conducted to quantify upland and stream corridor sources of suspended sediment and sediment-bound phosphorus using the Sediment Source Assessment Tool (SedSAT) methods with a suite of trace elements. Upland source samples were collected at 45 randomly selected sites in the...
