    "descript": "The U.S. Geological Survey St. Petersburg Coastal and Marine Science Center (USGS SPCMSC), collected single beam and swath bathymetry data from the northern Chandeleur Islands, Louisiana, in June of 2016. This USGS data release includes the resulting processed elevation point data (xyz) and an interpolated digital elevation model (DEM). This USGS data release provides 437-line kilometers (km) of processed single beam bathymetry (SBB) and interferometric bathymetry (IFB) data collected under Field Activity Number (FAN) 2016-335-FA. This FAN encompasses two subfans each of which represents one survey vessel; the research vessel (RV) Sallenger (subFAN 16BIM01) collected IFB data and the RV Jabba Jaw (subFAN 16BIM02) acquired SB) data. SBB and IFB point data (xyz) are provided in two datums; the International Terrestrial Reference Frame of 2008 (ITRF08) and ellipsoid height and the North American Datum of 1983 (NAD83) in the CORS96 realization for the horizontal and the North American Vertical Datum of 1988 (NAVD88), using the geoid model of 2009 (GEOID09), orthometric height for the vertical. Additional files provided in this data release include: trackline shapefiles, digital and handwritten field logs, and a comprehensive 50-meter (m) DEM. For additional information regarding data collection and processing of the sounding data, please refer to the field logs and formal Federal Geographic Data Committee (FGDC) metadata for the individual IFB and SBB point data (xyz) files and survey trackline shapefiles also included within this publication and available at, https:\/\/doi.org\/10.5066\/P993MBJK.",
