We measured soil CO2 fluxes on grids with the accumulation chamber method on July 15-17, 2021, September 10, 2022, and May 6-7, 2025, at Mud Volcano, an acid-sulfate, vapor-dominated area in Yellowstone National Park, WY. We also monitored variations in CO2, H2O and sensible and latent heat fluxes, air temperature and pressure, and wind speed and direction on a half-hourly basis from...

These data were collected as part of the USGS Sierra Nevada Forest Dynamics Study. They include tree mortality data from 30 plots located along an elevational gradient in the Sierra Nevada of California from 1982 to 2019. Although the data were collected annually, for purposes of compatibility with a global analysis, they were abstracted to five-year census intervals.

This dataset presents a recalculated compilation of geochronology ages of Cretaceous-Miocene intrusive rocks and volcanic plugs in the northern Rocky Mountains USA, with a focus on Montana and Idaho. Mineral assessments and prospectivity mapping requires detailed spatiotemporal understanding of magma systems in the upper crust to predict when and where ore deposits may have formed...

This data release contains data inputs for the Metapopulation Integral Projection Model (MetaIPM). These inputs include demographic rate data (such as fish growth) and movement rate data (such as fish movement across river pools). The data are designed to be downloaded by a Shiny Application (point-and-click version of the model). Each species and scenario requires its own data inputs...

This digital dataset was created as part of a U.S. Geological Survey (USGS) regional groundwater assessment of the eastern Great Basin; the project was called the Great Basin Carbonate-Alluvial Aquifer Study (GBCAAS). The study area has a geographic extent of 110,000 square miles, predominantly in eastern Nevada and western Utah. As part of this larger study, the USGS developed digital...

This data release contains sensor-based water-quality and discrete stable isotopes of water data collected along the Upper Colorado River. Data collection was made by the University of Colorado at Boulder, Colorado (CO), and the U.S. Geological Survey (USGS) in Lakewood, CO. The water-quality data were collected from an inflatable raft during 5 high flow and 3 low flow sampling campaigns...

The U.S. Geological Survey, in cooperation with the City of Brownsville, Texas, configured and calibrated a set of hydrologic models for a 217-square-mile study area in Cameron County in South Texas. The Hydrological Simulation Program—FORTRAN (HSPF) modeling system was used to simulate the hydrological conditions for the study area because it is one of the most comprehensive watershed...

This dataset provides monthly summaries of evapotranspiration (ET) data from OpenET v2.0 image collections for the period 2000-2024 for all National Watershed Boundary Dataset subwatersheds (12-digit hydrologic unit codes [HUC12s]) in the US that overlap the spatial extent of OpenET datasets. For each HUC12, the dataset contains spatial aggregation statistics (minimum, mean, median, and...

This dataset is from a vessel comparison study between four motorized research vessels (RVs) and one uncrewed surface vessel (USV) including the Ohio Department of Natural Resources (ODNR) RV Almar and RV Grandon, the U.S. Geological Survey (USGS) RV Muskie, the Ontario Ministry of Natural Resources (OMNR) RV Erie Explorer and a wind propelled USV (SD-1080; Saildrone Inc.). Paired...

Geochemical data include major, minor and trace element results for alkaline silicate igneous rock samples from the Bear Lodge alkaline complex. Samples were collected during field work from natural exposures/outcrops and drill core. Samples were analyzed by the GeoAnalytical Lab at Washington State University and U.S. Geological Survey contract laboratories, AGAT Labs and SGS Labs...

This geologic database is a digitized version of the original 1:48,000-scale analog geologic map titled "Geologic map of the Mohave Mountains area, Mohave County, western Arizona", published by the U.S. Geological Survey (USGS) in 1999. The Mohave Mountains area surrounds Lake Havasu City, Arizona, in the Basin and Range physiographic province. The Mohave Mountains and the Aubrey Hills...

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 smallmouth bass entrainment through Glen Canyon Dam and annual smallmouth bass population growth rate (lambda) in the Colorado River below Glen Canyon Dam. The...
