Bathymetric change map of the nearshore around Ship, Horn, and Petit Bois islands, Mississippi: 1916-1920 to 2016

Metadata Updated: November 19, 2025

To characterize coastal change, historical maps and complementary records were compiled including: topographic sheets (T-sheets), hydrographic sheets (H-sheets, smooth sheets), shorelines, and bathymetric soundings surrounding the Mississippi (MS) barrier islands over several time periods (1916-1920, 2008-2009 and 2016). One goal of this work was to create a time-series of bathymetric change maps around the islands. Datasets include 1916 through 1920 soundings collected by the United States Coast and Geodetic Survey as downloaded H-sheets and some digitized soundings from the National Oceanic and Atmospheric Administration (NOAA), 2008 to 2009 soundings collected by the United States Geological Survey (USGS) St. Petersburg and Woods Hole Coastal and Marine Science Centers (SPCMSC and WHCMSC respectively), and 2016 soundings collected by the SPCMSC in the nearshore environment of Ship, Horn, and Petit Bois Islands. This USGS data release includes three interpolated bathymetric change maps created by comparing the 1916 to 1920, 2008 to 2009, and 2016 bathymetry data. This metadata file pertains to the historical bathymetric change digital elevation model (DEM) resulting by subtracting the 1916-1920 bathymetry from the 2016 bathymetry (2016minus1916to1920_MS_NAD83NAVD88g12B_50m.tif). This work was completed in cooperation with the United States Army Corps of Engineers (USACE) Mobile, Alabama and the National Park Service (NPS) as part of the Mississippi Coastal Improvements Program (MsCIP).
