The U.S. Geological Survey, in cooperation with the City of South Padre Island, Texas, deployed an Acoustic Doppler Current Profiler (ADCP) to measure surface wave, pressure, and current-velocity data approximated 1-mile (1.61-kilometers) offshore from South Padre Island, Texas during August 2018–February 2019. The data were collected by using a trawl-resistant Teledyne Oceanscience Barnacle53 mounted uplooking ADCP deployed on the seabed. This part of the data release contains the data pertaining to wave velocities. Raw observations were collected at 1-minute intervals but are reported as the average values for to 10-minute intervals. All times are represented in Coordinated Universal Time (UTC). The measurements can be used to explore the oceanographic and sediment-transport processes associated with near-shore and beach erosion and deposition patterns.
