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 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,
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 waterborne self-potential (SP) logging data measured during 48 laboratory experiments and three field experiments that were performed to develop an efficient, accurate method for detecting (in the laboratory) and geolocating (in the field) focused vertical groundwater discharge (surface-water gains) and recharge (surface-water losses) in a river. The experimental procedures and results are described and interpreted in a companion journal article titled "Remote detection of focused groundwater/surface-water exchange in rivers using waterborne self-potential logging: Laboratory and field experiments," and are similar to waterborne SP logging data measured, modeled, and interpreted by Ikard...

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,...

This data release contains 82.4-kilometer (km) long spatial profiles of geophysical and water-quality properties data acquired along five semi-continuous segments of the Trinity River that were surveyed August 28 – September 1, 2023. The surveyed reaches start at the Elm Fork confluence in the Dallas, Texas metropolitan area and end at a pump station in Scurry, Texas. The geophysical dataset consists of a spatial profile of waterborne self-potential (WaSP) voltages attributed to changes in electrical potential along the surveyed reach. The water-quality properties data consist of spatial profiles of temperature, specific conductance, turbidity, pH, oxidation-reduction potential, and dissolved-oxygen concentration...
