Pueblo de San Ildefonso Landscape Management Literature Review Pueblo de San Ildefonso Landscape Management Literature Review
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 Groundwater Dye Tracing for Tennessee Communities, Water Year 2024 Karst Groundwater Dye Tracing for Tennessee Communities, Water Year 2024
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...
Dilation and slip tendency for a portion of the Southern Bartlett Springs fault and surrounding fault zones in the Wilbur Springs area, Northern California Coast Ranges Dilation and slip tendency for a portion of the Southern Bartlett Springs fault and surrounding fault zones in the Wilbur Springs area, Northern California Coast Ranges
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...
Digital drillhole lithologic data and a radiocarbon age -- data supporting interpretation of Quaternary depositional history in the vicinity of Fort Morgan, Eastern Colorado Digital drillhole lithologic data and a radiocarbon age -- data supporting interpretation of Quaternary depositional history in the vicinity of Fort Morgan, Eastern Colorado
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...
Estimated crop irrigation water use withdrawals in Willcox Groundwater Basin, Arizona for 2024 Estimated crop irrigation water use withdrawals in Willcox Groundwater Basin, Arizona for 2024
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
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...
