Coastal Bathymetry Data Collected in 2016 nearshore from West Ship Island to Horn Island, Gulf Islands National Seashore, Mississippi

This data release provides 667-line kilometers (km) of processed single-beam bathymetry (SBB) data and 773-line km of processed Interferometric Bathymetry (IFB) collected by the USGS SPCMSC in July 2016 (field activity number [FAN] 2016-347-FA). The IFB were acquired on board the Research Vessel (R/V) Sallenger (subFAN, 16BIM04), and the SBB was acquired on board the R/V Jabba Jaw (subFAN, 16BIM05) and the R/V Mako (subFAN, 16BIM06). The IFB and SBB point data are provided in three datums: 1) the International Terrestrial Reference Frame of 2000 (ITRF00), ellipsoid height (-49.70 meters [m] to -28.87 m); 2) the North American Datum of 1983 (NAD83) CORS96 realization and the North American Vertical Datum 1988 (NAVD88) with respect to the GEOID12B model (-0.07 m to ?20.69 m); and 3) NAD83 (CORS96) and Mean Lower Low Water (MLLW) (-0.04 m to -20.60 m). A comprehensive 50-meter Digital Elevation Model (DEM) created from the IFB and SBB point data is provided in NAD83 NAVD88 GEOID12B. Additional files include trackline shapefiles, respective digital and handwritten field logs, and formal Federal Geographic Data Committee (FGDC) metadata.
