Groundwater-quality data in the Modesto-Turlock-Merced Domestic-Supply Aquifer Study Unit, 2020-2021: Results from the California GAMA Priority Basin Project Groundwater-quality data in the Modesto-Turlock-Merced Domestic-Supply Aquifer Study Unit, 2020-2021: Results from the California GAMA Priority Basin Project
The U.S. Geological Survey collected groundwater samples from 71 wells used for domestic and small system drinking water supplies in Stanislaus and Merced counties of California during 2020-2021. The wells were sampled for the Modesto-Turlock-Merced Domestic-Supply Aquifer Study Unit of the State Water Resources Control Board Groundwater Ambient Monitoring and Assessment (GAMA) Program...
2020 Niobrara River Topobathymetric Lidar Validation – USGS Field Survey Data 2020 Niobrara River Topobathymetric Lidar Validation – USGS Field Survey Data
U.S. Geological Survey (USGS) scientists conducted field data collection efforts between August 17th and 28th, 2020 over a large stretch of the Niobrara River in Nebraska using high accuracy surveying technologies. The work was initiated as an effort to validate commercially acquired topobathymetric light detection and ranging (lidar) data. The goal was to compare and validate the...
Total and Methyl Mercury Water and Fish Concentrations within Everglades National Park Total and Methyl Mercury Water and Fish Concentrations within Everglades National Park
The data in this data release includes results from the analysis of water and fish from 76 sites in the Everglades National Park (ENP). Water and particulate matter samples were collected from 2008 to 2018 and analyzed for total mercury (THg) and methylmercury (MeHg). Filtered water samples were also analyzed for dissolved organic carbon (DOC), specific ultraviolet absorbance (SUVA), and...
Mean bed elevations of waterbodies on the Atchafalaya River floodplain Mean bed elevations of waterbodies on the Atchafalaya River floodplain
Waterbodies that exhibit persistent water and lack trees within the majority of its area are defined as open waterbodies by the National Hydrography Dataset (NHD, USGS, 2011). The data presented here were created to determine the volume of water for open waterbodies on the floodplain of the Atchafalaya River Basin. Open waterbodies and their surficial geometry were identified using a...
Assessing Exposure, Physiological Effects, and Geographic Scope of Anticoagulant Rodenticides in the Critically Endangered California Condor Assessing Exposure, Physiological Effects, and Geographic Scope of Anticoagulant Rodenticides in the Critically Endangered California Condor
-Test subject identification information (sample collection site and date, test subject identification number, and sample number) -Clotting time parameters and comments (prothrombin time, Russell’s viper venom time, fibrinogen concentration, and coefficient of variation for replicate analyses)
Data tables associated with velocity modeling of supercritical pore fluids through porous media at reservoir conditions with applications for petroleum secondary migration and carbon sequestration plumes Data tables associated with velocity modeling of supercritical pore fluids through porous media at reservoir conditions with applications for petroleum secondary migration and carbon sequestration plumes
A time-dependent form of Darcy's Law was used to model pressure-driven fluid flow within homogeneous, isotropic, low-permeability carrier beds exhibiting a broad range of rock and fluid properties likely encountered in a variety of sedimentary sequences (Burke, 2022). In the study by Burke (2022), thermodynamic equations of state were used to determine thermophysical properties of...
