The U.S. Geological Survey (USGS), in cooperation with the City of South Padre Island, Texas, deployed an acoustic Doppler current profiler (ADCP) to collect current velocity, wave height, and directional data in the lower Laguna Madre adjacent to South Padre Island, Texas. From July 19, 2022, through January 9, 2023, these data were collected at a site near South Padre Island (USGS station number 260551097100901) by using an up-looking acoustic doppler current profiler (ADCP) mounted on the bottom of the lower Laguna Madre. Raw data were collected at a frequency of 2 hertz (Hz); reported values were computed as the average of the processed data values for 60-minute intervals. All times are represented in Coordinated Universal Time (UTC).

The U.S. Geological Survey, in cooperation with the City of South Padre Island, Texas, collected base line hydrodynamic (tidal water level and current velocity) data for a near-shore area of the Laguna Madre near South Padre Island from August 18, 2021, to April 27, 2022. The data included in this data release are presented in a comma-separated values (csv) file format.

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.

These data contain groundwater level measurements at 55 locations, used in construction of the potentiometric map of the South Coast aquifer in the Santa Isabel area of southern Puerto Rico during March 31 to April 17, 2014. Measured values of the potentiometric surface ranged from -22.8 feet to 185.4 feet above mean sea level.

High resolution bathymetric, sea-floor backscatter, and seismic-reflection data were collected offshore of southeastern Louisiana aboard the research vessel Point Sur on May 19-26, 2017, in an effort to characterize mudflow hazards on the Mississippi River Delta front. As the initial field program of a research cooperative between the U.S. Geological Survey, the Bureau of Ocean Energy Management, and other Federal and academic partners, the primary objective of this cruise was to assess the suitability of sea-floor mapping and shallow subsurface imaging tools in the challenging environmental conditions found across delta fronts (for example, variably distributed water column stratification and widespread biogenic gas in the shallow subsurface). Approximately 675 kilometers (km) of multibeam bathymetry and backscatter data, 420 km of towed chirp data, and 550 km of multichannel seismic data were collected. Varied mudflow (gully, lobe), prodelta morphologies, and structural features were imaged in selected survey areas from Pass a Loutre to Southwest Pass.
