Data

These data describe tracking information and provide location data of American avocets (from 2023-03-18 to 2024-12-31) and Wilson’s phalaropes (from 2023-08-17 to 2023-11-10) collected in support of the U.S. Geological Survey Saline Lakes Ecosystems Integrated Water Availability Assessment Program (USGS SLE IWAA). The data are provided using standardized formats and an attribute...

This dataset consists of eight sandstone samples and four ash samples collected from the Bidahochi basin that were analyzed for U-Pb zircon ages. The dataset accompanies the publication "Late Miocene Colorado River arrival in Bidahochi basin permits spillover origin of Grand Canyon". Samples were collected from the field by Ryan Crow (USGS) and John Douglass (Paradise Valley Community...

Continuous 15-minute time-series suspended-sediment concentration (SSC) data computed from U.S. Geological Survey (USGS) instream turbidity data using a YSI EXO2 multi-parameter water quality sonde for the San Joaquin River at Prisoners Point near Terminous, California, USGS station #11313460. A Model Archive Summary (MAS) describes the development of a continuous 15-minute SSC time...

Methane gas bubbles emitted from the seafloor transport methane through the water column. Methane transport is important to track because of the substantial role methane plays in biological processes and in the Earth’s climate system. Existing models used to predict methane transport based on methane dissolution rates from rising bubbles generally estimate bubble rise velocity from the...

This report and accompanying maps and database address the geologic and geophysical character of a block of ten 7.5’ quadrangles that span the San Gorgonio Pass region. The study culminates more than four decades of intermittent geologic and geophysical mapping investigations by the U.S. Geological Survey (USGS). Published results from these investigations fall into two categories: (1)...

As part of the larger Great Lakes Cooperative Science and Monitoring Initiative (CSMI) , the U.S. Geological Survey Mercury, Metals, and Microplastics Research Laboratory (USGS M3RL) completed a binational assessment partnering with the U.S. Environmental Protection Agency (US EPA), Environmental Climate Change Canada (ECCC), Ontario Ministry of Natural Resources and Forestry (ONRF)...

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...

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...

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...

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...

This data release provides digital flight line data for a high-resolution airborne magnetic and radiometric survey over the Hartville Uplift and Shirley Mountains regions of Wyoming. The survey is split into two blocks, one covering the Hartville Uplift region (Block A), and the other covering the Shirley Mountains region (Block B). The airborne survey was mainly funded by the State of...
