Wassaw Sound (2014)
A 3 meter by 3 meter ESRI Grid file was generated to represent the Bathymetric surface of the Wassaw Sound, Georgia area. Bathymetric soundings, sidescan sonar imaging, and sediment grain size data were collected for selected areas of Wassaw Sound, Wilmington River, Bull River, Halfmoon River, and Romerly Creek in Chatham County, Georgia to accurately map bottom topography and habitat type in 2013 and 2014. Three methods of field data collection were utilized to efficiently acquire data for bathymetry across various environments within the study area. Swath Bathymetry was collected using an interferometric swath bathymetry sonar over 30 survey missions for all major channels and shoals where water depth exceeded 2-3 meters MLLW. Single Beam echosounder data was collected over 13 survey missions for shallow zones where water depth was below 2-3 meters MLLW. Topographic Laser data was collected over 2 survey missions for selected shallow shoals exposed at low tide. Existing Digital Elevation model (DEM) data from Chatham County, Georgia was incorporated for processing final Bathymetric data map. Bathymetric data was collected edited and processed using Hypack 2013 and ArcGIS 10.1 software.
