Datasets for Colorado River Basin Salinity Interactive Map Datasets for Colorado River Basin Salinity Interactive Map
Since its formation, the Colorado River Basin Salinity Control Forum and its partners have completed a substantial amount of work in an ongoing effort to reduce salinity concentrations and loads in the Colorado River. These efforts and related monitoring have generated a large volume of data and information. This data release includes geospatial datasets that provide information on...
Tables and figures for the unrecognized role of uranium transport in the Devils Hole, Nevada climate record Tables and figures for the unrecognized role of uranium transport in the Devils Hole, Nevada climate record
For more than a half million years, dense vein calcite has been precipitating in Devils Hole, located about 115 km northwest of Las Vegas, Nevada. This process also occurs in Devils Hole Cave 2, which is hydrologically connected and situated about 200 meters north of the original Devils Hole cave. Calcite has been precipitating in this natural laboratory in oxygen isotopic equilibrium at...
Local Demographic Rates of Four Eleutherodactylus Frogs in Puerto Rico, 2017-2019 (ver. 1.1, January 2025) Local Demographic Rates of Four Eleutherodactylus Frogs in Puerto Rico, 2017-2019 (ver. 1.1, January 2025)
We estimated the effect of microhabitat and microclimatic factors on occupancy, abundance and reproduction of four species of Eleutherodactylus frogs (E. wightmanae, E. brittoni, E. antillensis, E. coqui). Data consist of presence-non/presence data (binary), and physical (abiotic) and habitat (biotic) covariates collected at each of 48 survey stations (2017) and 35 (2018) along two...
Giving-up density experiments for two species of mammals in Florida, 2022 Giving-up density experiments for two species of mammals in Florida, 2022
Invasive predators pose a substantial threat to global biodiversity. Native prey species frequently exhibit naïveté to the cues of invasive predators, and this phenomenon may contribute to the disproportionate impact of invasive predators on prey populations. However, not all species exhibit naïveté, which has led to the generation of many hypotheses to explain patterns in prey responses...
Whole rock and portable XRF geochemistry data from Mesoproterozoic granitic rocks in the eastern Adirondack Mountains, New York Whole rock and portable XRF geochemistry data from Mesoproterozoic granitic rocks in the eastern Adirondack Mountains, New York
This data release includes whole rock (WR) and portable X-ray fluorescence (pXRF) geochemical data collected from the eastern Adirondack Mountains, NY. Whole rock geochemistry data were analyzed at Bureau Veritas Commodities Canada Ltd. Laboratories in Vancouver, British Columbia, Canada. Data were collected using a Thermo Niton portable X-ray fluorescence (XRF) spectrometer. Rock...
Contemporary estimates for total seep refugial capacity and contributing metrics, including likelihood of seep occurrence, seep air and water temperature variability, and probability of seep permanence Contemporary estimates for total seep refugial capacity and contributing metrics, including likelihood of seep occurrence, seep air and water temperature variability, and probability of seep permanence
We modeled the distribution and thermal and hydrologic stability of cliff-face seeps across moist portions of the Pacific Northwest, USA. We conducted surveys for cliff-face seeps across ~1,600km of roads, trails, and watercourses in Washington and Idaho and monitored water availability and air and water temperatures at a subset of these seeps. We detected 457 total seeps through an...
Vermont Flood of July 2023 Data Vermont Flood of July 2023 Data
A major rain event caused catastrophic flooding from July 9 through 12, 2023, in various portions of the State of Vermont, resulting in millions of dollars of damage. The high amount of rainfall caused several rivers to peak at record levels, in some cases exceeding records set by Tropical Storm Irene in 2011. President Biden approved an Emergency Declaration for Vermont on July 11, 2023...
Long-term trends in annual, seasonal, and monthly streamflow metrics at streamgages in the Upper Colorado River Basin, 1981-2022 Long-term trends in annual, seasonal, and monthly streamflow metrics at streamgages in the Upper Colorado River Basin, 1981-2022
Identifying long-term trends in water availability, including surface water quantity, is a key part of the U.S. Geological Survey (USGS) Integrated Water Availability Assessments (IWAAs) mission. This data release includes input and output data used in Mann-Kendall trend analyses to characterize streamflow conditions at 124 USGS streamgages in the Upper Colorado River Basin for water...
MODFLOW 6 models used to evaluate the accuracy of enhanced cell connectivity for simulation of flow through dipping aquifers MODFLOW 6 models used to evaluate the accuracy of enhanced cell connectivity for simulation of flow through dipping aquifers
This data release contains the MODFLOW 6 models described in the related Groundwater journal article (https://doi.org/10.1111/gwat.13459). The models are generalized cross-section models of a hypothetical and idealized aquifer. The models are used to examine the effects of layered or full grid connectivity with and without the XT3D option in the Node Property Flow (NPF) package of...
Rock mass quality and structural geology observations in Prince William Sound, Alaska (2023) Rock mass quality and structural geology observations in Prince William Sound, Alaska (2023)
Multiple subaerial landslides adjacent to Prince William Sound, Alaska (for example, Dai and others, 2020; Higman and others, 2023; Schaefer and others, 2024) pose a threat to the public because of their potential to generate ocean waves (Barnhart and others, 2021, 2022; Dai and others, 2020) that could affect towns and marine activities. One bedrock landslide on the west side of Barry...
Water Chemistry Data for Samples Collected at Groundwater Sites in the Midway-Sunset and Buena Vista Oil Fields Study Area, March 2018 to April 2019, Kern County, California Water Chemistry Data for Samples Collected at Groundwater Sites in the Midway-Sunset and Buena Vista Oil Fields Study Area, March 2018 to April 2019, Kern County, California
The California State Water Resources Control Board (State Water Board) initiated the Oil and Gas Regional Monitoring Program (RMP) to assess effects of oil and gas development on groundwater (GW) designated for any beneficial use. The U.S. Geological Survey (USGS) is the technical lead in conducting the RMP through the California Oil, Gas, and Groundwater (COGG) Program, working in...
Groundwater-flow model of the Wet Mountain Valley alluvial aquifer, Custer and Fremont Counties, Colorado Groundwater-flow model of the Wet Mountain Valley alluvial aquifer, Custer and Fremont Counties, Colorado
The U.S. Geological Survey in cooperation with the Upper Arkansas Water Conservancy District, created a numerical groundwater-flow model for the Wet Mountain Valley alluvial aquifer using the finite-difference MODFLOW code with the Newton formulation solver. This numerical groundwater-flow model simulates water-budget components, groundwater and surface-water interactions, and evaluates...
