Description
Summary: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 (USGS SPCMSC) conducted a single-beam and multibeam bathymetry survey around Breton Island, Louisiana (LA), from August 3-5, 2022, for Field Activity Number (FAN) 2022-325-FA. 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. The survey encompassed approximately 65 square kilometers of nearshore environment including the former Mississippi River to Gulf Outlet and submerged areas of South Breton Island. The single-beam bathymetry was acquired using two 12-foot personal watercrafts (PWCs) and a 20-foot Twin Vee. All vessels were outfitted with high precision Global Navigation Satellite System (GNSS) receivers, ...
