Stable carbon and oxygen isotope paleoclimate records of U.S. Geological Survey-collected samples from Devils Hole and Devils Hole Cave 2, Nevada

In support of paleoclimatology investigations, samples of mammillary calcite, calcitic folia, and flowstone were collected by the U.S. Geological Survey in Devils Hole and Devils Hole Cave 2, Nevada, between 1983 and 1996. These samples came from about 60 m below to 9 m above the modern water table in these caverns. To determine delta18O and delta13C time series spanning the interval 567.7-4.5 ka,

Delaware River near Wilmington Floating Electromagnetic Surveys from August 2020

Electromagnetic (EM) geophysical methods provide information about the bulk electrical conductivity of the subsurface. EM data has been widely used to investigate aquifers and geologic structures. In the following study, the United States Geological Survey conducted a boat-towed, waterborne transient electromagnetic (FloaTEM) survey to examine conductivity within the subsurface of the Delaware Riv

Data from Decadal Change in Groundwater Quality Web Site, 1988-2020

Evaluating Decadal Changes in Groundwater Quality: Groundwater-quality data were collected from 5,000 wells between 1988-2001 (first decadal sampling event) by the National Water-Quality Assessment Project. Samples are collected in groups of 20-30 wells with similar characteristics called networks. About 1,500 of these wells in 67 networks were sampled again approximately 10 years later between 20

Data release: Walleye Thermal Optical Habitat Area (TOHA) of selected Minnesota lakes

Climate change and land use change have been shown to influence lake temperatures and water clarity in different ways. To better understand the diversity of lake responses to climate change and give managers tools to manage individual lakes, we focused on improving prediction accuracy for daily water temperature profiles and optical habitat in 881 lakes in Minnesota during 1980-2018. The data are

Data release: Process-based predictions of lake water temperature in the Midwest US

Climate change has been shown to influence lake temperatures in different ways. To better understand the diversity of lake responses to climate change and give managers tools to manage individual lakes, we focused on improving prediction accuracy for daily water temperature profiles in 7,150 lakes in Minnesota and Wisconsin during 1980-2019. The data are organized into these items: Spatial data

MODFLOW-NWT and MODPATH6 model use to analyze remedial scenarios affecting plume movement through a sole-source aquifer system, southeastern Nassau County, New York

A three-dimensional steady-state groundwater flow model is coupled with the particle-tracking program, MODPATH, to assess the fate and transport of volatile organic compound plumes within the Magothy and upper glacial aquifers in southeastern Nassau County, NY. Knowledge of groundwater-flow patterns and rates is essential for effective management of groundwater resources and for mitigation of pot

Urbanization Impacts on Evapotranspiration Across Various Spatio-temporal Scales

The data in this release describe various aspects of the impacts of urbanization on evapotranspiration at local to global spatial scales. This data release is associated with the publication of these results in a concurrent journal article. Analyses in the journal article included comparisons between urban and non-urban ET in a variety of climate settings and spatial scales. Urbanization has been

MODFLOW-NWT model used in Simulation of Groundwater Flow, and Analysis of Projected Water Use for the Washita River Alluvial Aquifer, Western Oklahoma

In 2020 the U.S. Geological Survey, in cooperation with the Oklahoma Water Resources Board, published a calibrated numerical groundwater-flow model and associated model documentation report that evaluated the effects of potential groundwater withdrawals on groundwater flow and availability in the Washita River alluvial aquifer in western Oklahoma. The results of groundwater-availability scenarios

NHD-RC: Extension of NHDPlus Version 2.1 with high-resolution river corridor attributes

This hybrid medium-resolution national hydrography dataset with river corridor attributes (NHD-RC) for the conterminous United States (CONUS) was created by merging lentic and lotic attributes from the high-resolution NHDPlus (U.S. Geological Survey, 2020) into the medium-resolution NHDPlus Version 2.1 (U.S. Geological Survey, 2016). NHD-RC includes attributes from an additional 5.4 million small

Geospatial Datasets for Watershed Delineation Used in the Development of the USGS StreamStats Application for Puerto Rico

The U.S. Geological Survey (USGS), in cooperation with the Puerto Rico Environmental Quality Board, has compiled a series of geospatial datasets for Puerto Rico to be implemented into the USGS StreamStats application (https://streamstats.usgs.gov/ss/). These geospatial datasets, along with basin characteristics datasets for Puerto Rico published as a separate USGS data release (https://doi.org/10.

Spatial and tabular datasets of water withdrawals and use in Puerto Rico, 2015

The U.S. Geological Survey has compiled information on water withdrawal and use for Puerto Rico at 5-year intervals since 1980 to provide data for the management of the Commonwealth’s water resources. For 2015, water withdrawals and use were estimated for 78 municipalities from fresh groundwater and surface water in the categories of public use, domestic use, irrigation use, livestock, commercial

Mercury and selenium chemical characteristics and speciation data of bird, fish, and earthworm tissues

Birds (Clark's grebe, Aechmophorus clarkii; Forster's Tern, Sterna forsteri), fish (Peacock bass, Cichla temensis, Cichla monoculus; Pescada, Plagioscion squamosissimus) and earthworms were analyzed for selenium, total mercury, and methyl mercury concentration and mercury speciation. A Clark's grebe was collected from Lake Berryessa (California, United States) in September 2012. A Forster's Tern w
