Estimated Ages of Southern Beaufort Sea Polar Bears Based on DNA Methylation, 1987-2016 Estimated Ages of Southern Beaufort Sea Polar Bears Based on DNA Methylation, 1987-2016
This dataset contains known and estimated ages of polar bears sampled from the southern Beaufort Sea of Alaska. Whole blood was collected from polar bears of known chronological age between 1987 and 2016. Chronological age was known because all the bears in this data set were initially captured as a dependent cub-of-the-year, yearling, or 2-year-old, and that allowed us to know...
U-Pb Zircon Data for Igneous and Metaigneous Rocks of Interior and Southwest Alaska U-Pb Zircon Data for Igneous and Metaigneous Rocks of Interior and Southwest Alaska
This dataset contains U-Pb isotopic data and associated dates for sampled igneous, meta-igneous, and metamorphic rocks of interior and southwestern Alaska. Samples were collected during geologic mapping and mineral deposit research from 2019 to 2023. Mapping and research were funded by the Mineral Resources Program of the U.S. Geological Survey. Mineral separations were conducted at the...
Federal and Indian lands coal and other mineral production, value, and royalties by state, 1954-1980 and prior Federal and Indian lands coal and other mineral production, value, and royalties by state, 1954-1980 and prior
This data release includes a digitized version of the "Statistics by States, lands, products and years" section of the 1981 edition of the Federal and Indian lands coal, phosphate, potash, sodium, and other mineral production, royalty income, and related statistics publication. These data were published by the Conservation Division of the U.S. Geological Survey, which was tasked with the
High-resolution seismic imaging data from the West Napa Fault Zone acquired in 2015 at Hendry Winery, Napa, California High-resolution seismic imaging data from the West Napa Fault Zone acquired in 2015 at Hendry Winery, Napa, California
In February 2015, the U.S. Geological Survey conducted a high-resolution seismic survey across the West Napa Fault zone at Hendry Winery in Napa, California (Fig. 1). Geophones were deployed every 3 to 5 meters along a southwest-northeast trend to create an approximately 400-m-long linear array. Data were recorded by two Geometrics Stratavisor NZ-60TM seismographs. Both P-wave and S-wave...
Luminescence data for: Reconstructing the Quaternary depositional history using geologic mapping and a 3D model of the subsurface in the vicinity of Fort Morgan, Eastern Colorado Luminescence data for: Reconstructing the Quaternary depositional history using geologic mapping and a 3D model of the subsurface in the vicinity of Fort Morgan, Eastern Colorado
Centered on Fort Morgan, Colorado, this study is intended to build from previous work by adding a three-dimensional (3D) view of the subsurface to better understand the depositional history of Quaternary deposits. A 1:100,000 scale geologic map was made by combining previous geologic maps, regional soil maps, and recent field investigations. In addition to the geologic mapping, drill...
Datasets for Monitoring of a Passive-ISCO Experiment to Remediate a Chlorinated Ethene Plume, Naval Air Station Pensacola, Florida Datasets for Monitoring of a Passive-ISCO Experiment to Remediate a Chlorinated Ethene Plume, Naval Air Station Pensacola, Florida
Recalcitrant chlorinated ethenes in low-permeability units positioned adjacent to permeable aquifers are problematic because they are a prolonged source of contamination. Passive in situ chemical oxidation (P-ISCO) is a remediation method where the slow release of permanganate can oxidize chlorinated ethenes into less harmful chemicals. The success of P-ISCO is dependent on the...
