Coastal Multibeam Bathymetry Data Collected in August 2022 From Breton Island, Louisiana

As part of the restoration monitoring component of the Deepwater Horizon early restoration project, scientists from the U.S. Geological Survey St. Petersburg Coastal and Marine Science Center in St. Petersburg, Florida (USGS–SPCSMC), conducted a bathymetric survey near Breton Island, Louisiana (LA). During this study, multibeam bathymetry data were collected aboard the research vessel (R/V) Sallenger August 2-5, 2022, as a part of field activity number (FAN) 2022-328-FA. Single-beam and seismic data were also acquired as a part of this field activity, please refer to Lyons and others (2024) and Forde and others (2023) for further details. The purpose of data collection was to develop a baseline digital elevation model of the seafloor environment around Breton Island for comparison with both previous and future elevation assessments, and to evaluate elevation change following island restoration. For further information regarding data collection and/or processing methods, please refer to the associated metadata.
