Data

Data were collected as part of a long-term capture-recapture program to assess the population dynamics of two long-lived, federally endangered catostomids in Upper Klamath Lake, Oregon. Lost River suckers (LRS; Deltistes luxatus) and shortnose suckers (SNS; Chasmistes brevirostris) have been captured and tagged with passive integrated transponder (PIT) tags during their spawning...

Viral nervous necrosis is a neurologic disease that causes vacuolating lesions in the brain and retina of a broad range of marine fish species. The viral agent responsible is nervous necrosis virus (NNV), a Betanodavirus within the family Nodaviridae. Based on genetic characterization of the viral genome, at least four species of NNV are known to exist, though this diversity is likely...

Juvenile Chinook salmon (age 0 and age 1), steelhead, and sockeye salmon were tagged with acoustic transmitters and released at sites along the Yakima River in and below Yakima, WA from 2018 to 2024. Detection sites varied across years but included arrays placed at diversion dams, canals, hydropower facilities, and other locations throughout the Yakima and Columbia rivers. Study design...

Within New Jersey’s Raritan Basin Water Supply Complex, multiple lakes and reservoirs with persistent and recurrent cyanobacterial harmful algal blooms (cyanoHABs) discharge water which ultimately travels downstream in surface water to drinking-water intakes. Cyanobacteria and other water-quality data were collected as part of a collaborative study among multiple agencies, including the...

The recently launched Surface Water and Ocean Topography (SWOT) satellite provides observations of Earth’s rivers and lakes, which sets the stage for innovative application of such data for hydrologic analysis. Here, we apply the LakeFlow algorithm, which leverages mass conservation principles and Bayesian optimization, to estimate lake inflow and outflow discharge at 1,061 North...

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...
