These data are chemical analyses of discrete samples of groundwater, stream base flow, and springs collected to support a U.S. Geological Survey study to estimate the timing and source of recharge to the basalt groundwater system in the Umatilla River basin, Oregon. Categories of data include: (1) site information (2) field measurements, (3) tracers of groundwater age and source, and (4) dissolved noble gases. These data were collected during August 26, 2014 – September 13, 2022. Data are in .csv file format.

These data are solubility calculations for dissolved gases in groundwater samples collected to support a U.S. Geological Survey study to estimate the timing and source of recharge to the basalt groundwater system in the Umatilla River basin, Oregon. The software package Dissolved Gas Modeling and Environmental Tracer Analysis (DGEMTA; Jurgens and others, 2020) was used to develop the solubility calculations. DGMETA produces estimates of dissolved gas concentrations during recharge as well as estimates of recharge temperature, excess air, and excess nitrogen gas concentrations by optimizing the solutions of solubility equations for multiple gases dissolved in samples of groundwater. These data were collected during...

This dataset, VegDischarge v1, represents a significant contribution to the understanding of hydrological dynamics across Africa from 2000 to 2021. It encompasses high-resolution (1km x 1km) monthly raster data of deep drainage, surface runoff, and total runoff, derived from the VegET (VegetationEvapoTranspiration) hydrological model (Senay et al., 2023). Additionally, routed discharge data (Mizukami et al., 2021) for over 63,000 river segments is provided, employing different routing algorithms (DW, KW, KWT, MC, and IRF) to demonstrate variability in river discharge patterns. This comprehensive dataset is stored in NetCDF and Shapefile formats, offering valuable insights for policymakers, stakeholders, and researchers...

The estimation and mapping of actual evapotranspiration (ETa) is an active area of applied research in the fields of agriculture and water resources. Thermal remote sensing-based methods, using coarse resolution satellites, have been successful at estimating ETa over the conterminous United States (CONUS) and other regions of the world. In this study, we present CONUS-wide ETa from Landsat thermal imagery-using the Operational Simplified Surface Energy Balance (SSEBop) model in the Google Earth Engine (GEE) cloud computing platform. Over 150,000 Landsat satellite images were used to produce 10 years of annual ETa (2010-2019). The accuracy assessment of the SSEBop results included point-based evaluation using monthly...
Data from 391 boreholes (including coreholes) that penetrated buried pre-Cretaceous basement rocks that lie beneath Atlantic Coastal Plain sedimentary deposits in Georgia and South Carolina were compiled from non-proprietary, mostly published sources in order to support subsurface geologic mapping, geologic interpretation of geophysical data (aeromagnetic, gravity, seismic), topical studies as in geochronology, and applications ranging from mineral, energy, and water resources to earthquake hazards in the Charleston seismic zone. Most of the entries are based on previous literature. In a few cases where noted, drill cores or cuttings were examined for basic geologic observations. Boreholes into bedrock beneath the...

This U.S. Geological Survey (USGS) data release contains the results from the 2017 geomorphic survey of North Fork Eagle Creek, New Mexico. The 2017 geomorphic survey was conducted by the USGS, in cooperation with the Village of Ruidoso, New Mexico, and is the first in a planned series of five annual geomorphic surveys of the stream reach located between the North Fork Eagle Creek near Alto, New Mexico, streamflow-gaging station (USGS site 08387550) and the Eagle Creek below South Fork near Alto, New Mexico, streamflow-gaging station (USGS site 08387600). Specifically, this data release contains the results from 14 cross-section surveys (to include x-y-z coordinates of all cross-section points), the locations of...

This USGS data release presents data used to estimate and summarize where and when recharge occurs to the Columbia River Basalt Group (CRBG) in the Umatilla River basin, Oregon, 2014–2022. The supplemental data consist of two child items. The child items are: (1) Discrete geochemical data for groundwater and surface water samples in the Umatilla River basin, 2014–2022, and (2) Dissolved gas solubility calculations for groundwater samples collected in the Umatilla River basin, Oregon, 2014–2019
