Data

This legacy dataset includes digitized ground temperatures from four borehole sites in Utqiagvik, Alaska. The data were measured by scientists from the Naval Arctic Research Laboratory (NARL) on a weekly to biweekly frequency spanning 1950 to 1961. The datasets include ground temperatures at approximately 15-24 depth increments down to 60-110 ft (28-33 m) (with higher measurement...

Open-graded friction course (OGFC) pavement is a layer of porous asphalt spread over the surface of impervious dense-graded hot-mix asphalt that is traditionally used as the wearing surface in Massachusetts. Benefits of OGFC pavement include noise reduction, less vehicular spray, hydroplaning, and surface reflectivity, and often provides measurable improvements in concentrations of...

The AltEn bioenergy plant (Mead, Nebraska, USA) previously (2015 to 2021) generated ethanol from almost 100% unused/expired treated corn seeds. This use of treated corn seeds as a feedstock for ethanol production resulted in accumulation of large amounts of contaminated wastewater and solid residue at the plant, a portion of which was applied to surrounding farmland. To better understand...

A novel U.S. Geological Survey-developed active water sampler was deployed at Ulatis Creek in Solano County, California for 24 hours from November 15, 2023 to November 16, 2023. Discrete surface water samples were collected at the start and end points of the active water sampler deployment interval for comparison to the active water sampler. Samples from the active water sampler and the...

Zooplankton samples were collected in the summer/fall of 2024 at multiple sites in the Sacramento River, Yolo Bypass, and Cache Slough Region of California and analyzed for a suite of 160 current-use pesticides and pesticide degradates by the U.S. Geological Survey Organic Chemistry Research Laboratory. Samples were collected at two sites in the Bypass, at a comparison site on the...

This dataset contains estimated time-weighted average water concentrations and quality control samples for pesticide, organic wastewater compound (OWC) and polycyclic aromatic hydrocarbon (PAH) data determined from samples collected with instream passive samplers in the Big Darby Creek Basin, Ohio, 2020-21.

This dataset contains sample collection details, analytical measurements of carbon content, and estimated petrogenic carbon contents of soil samples and shale samples collected from two locations in the Colorado Rocky Mountains.

Per- and polyfluoroalkyl substances (PFAS) are a class of ubiquitous, environmentally persistent compounds that pose a threat to human and wildlife health. Ospreys (Pandion halieatus) are a model avian species with a documented history of serving as effective bioindicators of contamination. Our study aims to provide a more thorough understanding of PFAS presence in the Chesapeake and...

This study assessed site-specific differences in PFAS in fish from Ashumet Pond (2020 & 2022), Sudbury River (2023), and Great Herring Pond (reference site; 2022) in Massachusetts. Largemouth bass were collected from all sites and banded killifish were collected from Ashumet Pond only. Health assessments were performed and included histology of the liver, spleen, kidneys, gonad, and any

Lake Superior is historically a nutrient poor lake that does not typically support significant cyanobacterial blooms. However, the lake has been experiencing an increase in blooms in the western portion of the basin recently. The largest blooms documented have occurred after recent major flooding events, indicating that nutrients transported to the lake during these events may be a...

Phosphorus, nitrogen, chloride, and suspended-sediment loads, in 24 U.S. tributaries of the Great Lakes, were estimated using U.S. Geological Survey (USGS) data from the Great Lakes Restoration Initiative (GLRI) monitoring program for the period Oct 2010 through Sept 2023 (USGS water years 2011-23). Specific water-quality constituents include total phosphorus, orthophosphate, particulate

Select photographic sequence of a Burmese Python (Python bivittatus) nesting in the wild within a concrete pipe from 01 June 2022 through 01 August 2022 in Big Cypress National Preserve within the Greater Everglades Ecosystem, Florida, USA. This python was tracked to an area of abandoned construction pipes and discovered inside to have oviposited. Throughout incubation, the python was...
