The East River is an agricultural tributary to the Lower Fox River and the Environmental Protection Agency (EPA) Green Bay Area of Concern (AOC) in northeast Wisconsin. This tributary has known excessive phosphorus (P) and suspended sediment loads that contribute to habitat related impairments and downstream algal blooms. As part of the Great Lakes Restoration Initiative (GLRI), the U.S

This data release contains measurement‑accuracy information derived from angler‑reported fish lengths submitted through a smartphone mobile application. The dataset includes records from multiple fishing events across the United States and Canada in which participating anglers self‑reported total length (TL) for each catch. Lengths were subsequently reviewed and verified by app staff...

Thermistor strings with sensors spaced at 25-centimeter intervals were installed in three boreholes extending from the ground surface to depths of up to 4.25 meters at Barter Island, Alaska. The sites were located near the bluff edge overlooking the open Beaufort Sea coast. Temperature measurements were programmed to be collected hourly from late spring through early fall in 2016 (May 31...

Uncrewed aerial system (UAS) imagery was collected over Cinder Lake Crater Field near Flagstaff, Arizona, a training site constructed in the late 1960s as a lunar analog site for Apollo astronauts and continues to serve as an operational analog environment. The DEM supports terrain analysis, visualization, illumination modeling, and mission simulation activities associated with planetary...

This data release is companion to a manuscript entitled: "Long-term intermittent connection between the western Snake River Plain and Columbia Basin: a two-phased incision history of Hells Canyon". Here, we report the measured flow direction and compositions of clasts and detrital zircon U-Pb ages from samples collected from modern and ancestral rivers near the Lewiston Basin region. The...

The data tables in this product include concentrations, detection frequencies, benchmark exceedances, and trends of pesticides in riverine surface water samples. The data are a product of a national-scale assessment of the status and trends of 84 pesticides at 81 sites during water years 2013 - 2022 conducted by the U.S. Geological Survey (USGS) National Water Quality Program. Data were...

These data were compiled as part of an experimental study investigating alternative methods to dryland reclamation. The objective of our study was to evaluate the effects of conventional vs alternative approaches alone and in combination that included different seeding methods, seed mixes, and biological soil crust (biocrust) inoculation. These data were collected within the footprint of...

Radiometric data were collected at the Grand Junction Regional Airport radiometric calibration facility in March 2023 and August 2024. The facility consists of five ~9 by ~12 m (30 x 40 feet) concrete pads, each 18 in thick. Each pad provides sources of radioelements that are spatially homogeneous (see Ward, 1978). Three pads are dedicated K, Th, and U pads, each of which contains high...

Streamgaging weirs, like the ones used by the U.S. Geological Survey (USGS), play a critical role in providing accurate and stable streamflow data, but their presence can affect the passage of diadromous fish species such as river herring and American shad. In some situations, weirs existing in rivers and streams are no longer used because they were part of a farm irrigation system or...

Clear Lake is a 180 km2 freshwater lake located approximately 120 km northwest of Sacramento in the California Coast Range. The lake is a popular sport-fishing destination, however, there are fish consumption advisories associated with mercury (Hg) contamination for several species. The lake has three arms: a large open-water region to the northwest (Upper Arm), a smaller and narrower...

This dataset was compiled and analyzed to support the goals of quantifying groundwater contributions to Lake Huron and exploring the impacts of groundwater on Lake Huron processes in accordance with the Lake Huron Cooperative Science and Monitoring Initiative 2022 field season. This data release contains three child items that describe 1) the characterization of the Lake Huron Basin into

Seeds extracted from the gastrointestinal contents of Burmese pythons (Python bivittatus) and Black and White Tegu (Salvator merianae) lizards in South Florida were sorted and identified to genus or species. Seeds were then categorized as invasive (category I: history of negative impacts or category II: potential for negative impacts), native, non-native, threatened, endangered, and...
