Modeled dissolved oxygen and water temperature in the Colorado River in Glen and Grand Canyons in support of resource impact analysis for Post-2026 reservoir operational alternatives Modeled dissolved oxygen and water temperature in the Colorado River in Glen and Grand Canyons in support of resource impact analysis for Post-2026 reservoir operational alternatives
These data were compiled in support of the Post-2026 Operational Guidelines and Strategies for Lake Powell and Lake Mead (Post 2026) Environmental Impact Statement (EIS). These data were outputs from models that estimate annual minimum dissolved oxygen and daily water temperature in the Colorado River below Glen Canyon Dam. The objective of our study was to predict water temperatures and...
Movement data of Brown Pelicans from the Eastern Shore of Virginia Movement data of Brown Pelicans from the Eastern Shore of Virginia
Two data files are included. The first includes GPS locations (~ 22k) of adult brown pelicans (n = 7) and the second includes characteristics of foraging trips (n = 552) from these same seven birds. Pelicans were outfitted with GPS satellite tags during incubation and data collected for the longevity of the tag. Movement data were used to define use areas during the breeding season...

This data release provides the concentration and quality-assurance results for inorganic constituents analyzed in water-quality samples from 26 residential and commercial tapwater locations in Montana by the U.S. Geological Survey (USGS) Environmental Health Program (EHP), Tapwater Exposure Study. The samples were collected between June 10-12, 2024, from both public supply (8) and...
MidFish: A Large-Scale Aggregation of State Fisheries Data from the Midwestern United States from 1940 - 2023 MidFish: A Large-Scale Aggregation of State Fisheries Data from the Midwestern United States from 1940 - 2023
Lakes in the Midwestern United States support valuable recreational, subsistence, and tribal fisheries. Fisheries assessments that support management decisions are typically conducted within political boundaries and at intervals that limit their spatial and temporal scope. Data aggregation across lakes and regions facilitates research extending across ecological gradients and...
Target chemical concentrations of mixed-organic compounds and microbiological indicators in tapwater, Montana, 2024 Target chemical concentrations of mixed-organic compounds and microbiological indicators in tapwater, Montana, 2024
This data release reports the concentration results for organic compounds (disinfection byproducts [DBP], pesticides, per- and polyfluoroalkyl substances [PFAS], pharmaceuticals and volatile organic compounds [VOC]), cyanotoxins, microbiological indicators, as well as radon-222 analyzed in samples collected from private well and public supply sourced tapwater samples from a community in...
