Chemical analyses and histopathology of organisms and plants collected from breccia pipe uranium mine sites in the Grand Canyon watershed, 2015-2020 Chemical analyses and histopathology of organisms and plants collected from breccia pipe uranium mine sites in the Grand Canyon watershed, 2015-2020
These data are comprised of measurements of aluminum, iron, cobalt, nickel, copper, zinc, arsenic, selenium, molybdenum, silver, cadmium, thallium, lead, bismuth, thorium, uranium, and mercury in invertebrates, vegetation, and small rodents. Gross alpha activity, gross beta activity, and radionuclide activities (isotopic U, isotopic Th) are also presented for vegetation; radioactivities...
Evapotranspiration Units, Groundwater Discharge Area, and 2007-2008 Summer Mean Vegetation Index for Tule Valley and part of Sevier Valley, Utah Evapotranspiration Units, Groundwater Discharge Area, and 2007-2008 Summer Mean Vegetation Index for Tule Valley and part of Sevier Valley, Utah
This USGS data release consists of three data sets used as the basis for estimates of groundwater discharge from evapotranspiration in Tule Valley and part of Sevier Valley, UT. The data sets are a mapped groundwater discharge area (GDA), a mean modified soil adjusted vegetation index (MSAVI), and evapotranspiration (ET) units derived from the MSAVI within the GDA. The GDA represents the...
Time-Domain Electromagnetic Data Used in the Assessment of the Freshwater/Saline-Water Transition Zone within the Hueco Bolson, Fort Bliss Area, El Paso, Texas 2017-2019 Time-Domain Electromagnetic Data Used in the Assessment of the Freshwater/Saline-Water Transition Zone within the Hueco Bolson, Fort Bliss Area, El Paso, Texas 2017-2019
Declining groundwater levels in the Hueco Bolson have raised concerns about the amount of available groundwater and the potential for water-quality changes. Fresh groundwater stored in the aquifer is bordered by regions of brackish-to-saline groundwater, and as the water levels in the Hueco Bolson have declined the local and regional hydraulic gradients have been altered such that the...
Asian carp eDNA and egg morphology data collected from Truman Reservoir tributaries, Missouri, USA, 2014 Asian carp eDNA and egg morphology data collected from Truman Reservoir tributaries, Missouri, USA, 2014
Ichthyoplankton tows samples collected from Truman reservoir tributaries evaluated for eDNA. Data also includes hydrologic and water quality parameters and morphology of grass carp eggs.
trajPipeFlow, Discharge from horizontal and vertical flowing pipes by trajectory methods trajPipeFlow, Discharge from horizontal and vertical flowing pipes by trajectory methods
The trajPipeFlow package in the R language provides functions for computation of discharge from horizontal and vertical flowing pipes using trajectory methods of the U.S. Bureau of Reclamation Water Measurement Manual (2001, chap. 14, sec. 13).
Water quality of precipitation and streamflow, with air temperature data, in four Kentucky, Appalachian watersheds - 1971 to 2018 Water quality of precipitation and streamflow, with air temperature data, in four Kentucky, Appalachian watersheds - 1971 to 2018
Context: The freshwater resources of the Central Appalachian region are impacted by stressors operating on multiple spatial scales, from local land use and land management (e.g., timber harvests and surface mining) to regional air quality patterns (e.g., pollutant emissions) and broader-scale climate variability. In order to isolate the effects of any of these stressors on water...
