Data Releases

To meet the goals of the project, the Pueblo de San Ildefonso’s Department of Environmental and Cultural Preservation (DECP) first undertook a literature review of existing data and information to identify relevant materials, reach out to partners at nearby public lands, and conduct a targeted literature search. The literature review incorporates 79 resources (i.e., media article...

Karst hydrologic systems are important resources in the state of Tennessee, both as drinking water resources and as centers for possible biological diversity. These systems are susceptible to contamination due to the inherent connectivity between surface water and groundwater systems in karst systems. A partnership between the U.S. Geological Survey (USGS) and Tennessee Department of...

This dataset presents modeled values of dilation tendency and slip tendency for faults within and surrounding the Wilbur Springs region of northern California, including the Bartlett Springs Fault, Cross Springs Fault, Little Indian Valley Fault Zone, and a network of secondary structures. The region is actively deforming, as evidenced by ongoing uplift and folding, suggesting it is...

This data release contains digital location and downhole lithologic data for 3,564 drillholes from along a portion of the South Platte River in eastern Colorado. The drillholes are located within the east half of the Greeley and the west half of the Fort Morgan USGS 1:100,000 scale maps. Subsurface lithologic data is intended to extend the results of surficial geologic mapping to the...

Observations of irrigated agricultural land within the Willcox Groundwater Basin in Arizona. Crops were verified in situ three times in 2024, first on May 29th, then on Sep 11th, and finally on Jan 15th; based on digitized field boundaries. Field boundaries were digitized from U.S. Department of Agriculture, National Agriculture Imagery Program County Mosaic 2023 imagery for Arizona and

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...

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...

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

At 4:17 am local time on February 6, 2023, a Mw 7.8 earthquake occurred in southeastern Turkiye. About nine hours later, a Mw 7.5 earthquake occurred about 95 km to the north of the Mw 7.8 earthquake, and over the following months, numerous aftershocks followed the main two earthquakes. To record aftershocks of the earthquake sequence, in July 2023, the U.S. Geological Survey and the...

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...

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...

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...
