This data release contains waterborne gradient self-potential (SP), surface-water temperature, surface-water conductivity and specific conductance, and surface-water nitrate concentration data measured continuously in the upper part of the Delaware River along approximately 123 kilometers (km) between Hancock and Port Jervis, New York. All of the data were measured from a kayak between June 27 and July 2, 2021. Gradient self-potential data were measured along five survey segments that varied in length between 13.1 and 31.6 km. The first segment began at Hancock, N.Y. on the east branch of the Delaware River, progressed into the main stem, and ended about 13.1 river-km downstream in Lordville, N.Y. at U.S. Geological...

This data release has been deprecated. Please see new data release here: https://doi.org/10.5066/P9CIK9ZF. This data release documents the digital data used to produce flood-inundation maps for a range of gage heights (stages) for the Sabinal River near Utopia, Tex. The simulated flood-inundation maps correspond to a range in stage from 7 to 24 feet (ft) at U.S. Geological Survey (USGS) streamgage 08197970 Sabinal River at Utopia, Tex. at intervals of 0.5-ft. The maps were created for a 10-mile reach of the Sabinal River from USGS streamgage 08197936 Sabinal River below Mill Creek near Vanderpool, Tex., at the upstream boundary of the study reach, to USGS streamgage 08197970 Sabinal River at Utopia, Tex. (hereinafter...

The maps were created for a 10-mile reach of the Sabinal River extending from USGS streamgage 08197936 Sabinal River below Mill Creek near Vanderpool, Tex. to USGS streamgage 08197970 Sabinal River at Utopia, Tex. (hereinafter referred to as the “Utopia gage”)...
This data release provides gradient self-potential (SP), conductivity, and temperature measurements made during an investigation of surface-water and groundwater exchange in Lake Travis near Austin, Texas, where the Colorado River is incised into two zones of the Cretaceous-age Trinity aquifer (the lower-zone, and several hydrostratigraphic units of the middle zone). The voltage, temperature, and conductivity data contained herein were continuously logged along three longitudinal profiles with the logging sensors positioned at depths of 3.0 and 6.1 meters vertically below the surface of Lake Travis, and in a cove along a fourth continuous, non-linear profile of intersecting tracks with the logging sensors positioned...
This data release contains geophysical and water-quality property data measured by the U.S. Geological Survey (USGS) along downstream continuous profiles in surveyed reaches of Elm Brook, Hartwell Brook, and the Shawsheen River near Hanscom Air Force Base in Bedford, Massachusetts. The geophysical data consist of spatial profiles of waterborne self-potential (WaSP) voltages attributed to changes in electrical potential along the respective reaches of each stream. The water-quality data consist of spatial profiles of temperature, specific conductance, turbidity, pH, and optical dissolved-oxygen concentration measured in situ in the streams on September 8 and September 10, 2023. A 190-meter (m) long reach of Hartwell...

Gradient self-potential,
The Triangle Chemical Company Superfund site, in Orange County, Texas, was a chemical mixing and blending facility in the 1970s. According to the Environmental Protection Agency (EPA), poor waste management practices resulted in soil and groundwater contamination and fish-kills in Coon Bayou (U.S. Environmental Protection Agency, 2023). The Five-Year Review of the Triangle Superfund Site indicated groundwater in the upper water-bearing zone might be migrating off-site toward the southwest (U.S. Environmental Protection Agency, 2016). There are concerns regarding potential risks to human health from contaminated soil vapor in existing or future structures in the area. To evaluate the status of volatile organic compound...
This data release contains time-lapse self-potential, electric resistivity tomography, hydrographic, and weather data acquired during a geoelectric monitoring survey of the lower Rio Grande riverbed in the Mesilla Basin of southeast, New Mexico. The monitoring survey was performed by the U.S. Geological Survey (USGS) in cooperation with New Mexico State University (NMSU), Elephant Butte Irrigation District (EBID), and hydroGEOPHYSICS, Inc (HGI). The data and corresponding data processing codes are described in the larger work citation, a journal article titled "Geoelectric Monitoring of the Electric-potential Field of the Lower Rio Grande Before, During, and After Intermittent Streamflow, May-October, 2022." The...
This data release contains waterborne gradient self-potential (SP), surface-water temperature, and surface-water conductivity data measured continuously along approximately 72 kilometers (km) of the Rio Grande over the Mesilla part of the Hueco–Mesilla Bolson aquifer. The geophysical measurements were made from a kayak between June 26, 2020 and July 2, 2020 during peak releases of surface-water in the range of 54 to 65 cubic meters per second from Elephant Butte and Caballo Dams upstream from the surveyed reach. The full geophysical survey extended between Leasburg Dam in Leasburg Dam State Park, New Mexico, and the Farm to Market (FM) 259 bridge in Canutillo, Texas. For data-collection purposes, the full survey...
This data release contains self-potential (SP) map data, two-dimensional electrical resistivity tomography (ERT) data, and time-lapse SP-monitoring data measured within the thermal springs discharge area of Hot Springs National Park in Hot Springs, Arkansas, in addition to the geospatial coordinates of each geophysical measurement and photographs of the reconnaissance and monitoring-survey layouts. Hot Springs National Park features 47 artesian thermal springs that discharge along the trace of a thrust fault at the base of Hot Springs Mountain. To better understand temporal aspects of thermal springs discharge at Hot Springs National Park, the U.S. Geological Survey, in collaboration with the U.S. National Park...
Geophysical data were collected on January 13, 2022, from a reach of East Fork Poplar Creek in Oak Ridge, Tennessee to gain a better understanding of surface water/groundwater exchanges. This data release contains the following types of data: waterborne self-potential (WaSP), and surface -water temperature and conductivity data collected by the U.S. Geological Survey (USGS) from 220-meter (m) long survey reach, stream specific conductance data calculated from surface-water temperature and conductivity, and electric resistivity tomography (ERT) data collected along four linear profiles on the floodplain adjacent to the WaSP survey reach. The ERT data were measured by hydroGEOPHYSICS, Inc. The WaSP logging data were...

This data release contains waterborne self-potential (WaSP) and surface-water (SW) temperature, conductivity, and specific conductance data measured by the U.S. Geological Survey (USGS) along a 43.2-kilometer (km) long profile in the Elm Fork of the Trinity River upstream from the Dallas, Texas, metropolitan area. The WaSP data were measured from a kayak during January 25–27, 2022, along three survey segments between Lewisville Lake Dam and Frasier Dam Recreational Area. The first segment was surveyed on January 25, began a short distance downstream from Lewisville Lake Dam, and ended about 19.2 river-km downstream, a few meters upstream from Carrollton Dam in McInnish Park. The second was surveyed on January 26,...
