Summary
Beaches and water recreation are important to the South Padre Island, Texas area and across the United States. The movement of sediment in channels along beaches and the nearshore environment is important for coastal stakeholders and resource managers. Sediment removed by maintenance dredging is often placed back into the littoral system for potential beach replenishment. The movement of sediment from offshore berms to onshore beaches is not well known. Sediment transport is highly dependent on local current conditions and seasonal conditions. The U.S. Geological Survey, in cooperation with the City of South Padre Island, completed an oceanographic field study from August 2018 to February 2019 to investigate the potential for beach [...]
Summary
Beaches and water recreation are important to the South Padre Island, Texas area and across the United States. The movement of sediment in channels along beaches and the nearshore environment is important for coastal stakeholders and resource managers. Sediment removed by maintenance dredging is often placed back into the littoral system for potential beach replenishment. The movement of sediment from offshore berms to onshore beaches is not well known. Sediment transport is highly dependent on local current conditions and seasonal conditions. The U.S. Geological Survey, in cooperation with the City of South Padre Island, completed an oceanographic field study from August 2018 to February 2019 to investigate the potential for beach replenishment by associated dredge material placed just offshore of South Padre Island, Texas. This child item contains the currents observations that were collected during the study.
This dataset provides the currents data that were obtained during an oceanographic field study from August 2018 to February 2019 to investigate the potential for beach replenishment by associated dredge material placed just offshore of South Padre Island, Texas. A Teledyne Oceanscience Barnacle53 trawl-resistant frame-mounted acoustic Doppler current profiler (ADCP) was deployed to the seabed approximated 1-mile (1.61-kilometers) offshore, east of the coastline. The ADCP was deployed to measure surface waves, pressure, and current velocity. The measurements will be used to explore the oceanographic and sediment-transport processes responsible for the movement and distribution of sand along under-water ridges (shoals) that runs parallel to the shore near South Padre Island, Texas. The background and experimental setup are described in the extended abstract "Monitoring Hydroacoustic Flow and Tracers of Offshore Dredge Material near South Padre Island, Texas", on line at: https://www.sedhyd.org/2019/openconf/modules/request.php?module=oc_program&action=view.php&id=244&file=1/244.pdf.
