In accordance with SO #3423 - The Gulf of America and SO #3424 - Mount McKinley and Landmarks Honoring the Alaskan People, new USGS data releases specific to those named places will utilize the new name Gulf of America and the restored name Mount McKinley. Per USGS practice, historical data will retain the name of the geographic features as they were known at the time the data were originally released.

Summary
As part of the Louisiana Coastal Protection and Restoration Authority’s Barrier Island Comprehensive Monitoring Program (BICM), scientists from the U.S. Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center conducted a nearshore single-beam bathymetry survey along the Chenier Plain, Louisiana, from Marsh Island to Sabine Pass. The goal of the BICM program is to provide long-term data on Louisiana’s coastline and to use this data to plan, design, evaluate, and maintain current and future barrier island restoration projects. The data described in this report will provide baseline bathymetric information for future research investigating island evolution, sediment transport, and recent and long term geomorphic change, and will support modeling of future changes in response to restoration and storm impacts. Over 3,300 line kilometers of single-beam data were acquired during two field missions, USGS Field Activity numbers 2017-323-FA, June 2–14, and 2017-324-FA, July 8–16, 2017, aboard 4 separate survey vessels. The final x,y,z data are provided in the native format of WGS84 G1150 (ITRF00), values ranging from -26.62 m to -69.94 m Ellipsoid height, as well as NAD83 NAVD88 Geoid 12A, with values ranging from 0.00 to -42.19 m. Supplemental data products include 200 m cell-size interpolated bathymetry grids, trackline maps, Field Activity Collection System logs, x,y,z point data files and formal Federal Geographic Data Committee (FGDC) metadata.
