82.4-kilometer profiles of waterborne self-potential and water-quality data measured August 28–September 1, 2023, in the Trinity River between the Elm Fork confluence and North Texas Municipal Water District Main Stem Pump Station in Scurry, Texas

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 measured in-situ in the surface water. The combined datasets consist of 78,745 measurements of WaSP voltages and water-quality properties, and the geospatial coordinates of each measurement.
