Sapelo Sound (2017)
A 3 meter by 3 meter ESRI Grid file was generated to represent the Bathymetric surface of Sapelo Sound, Georgia area. Bathymetric soundings, sidescan sonar imaging, and sediment grain size data collection were conducted for selected areas of Sapelo Sound, Sapelo River, and South Newport River in McIntosh County, Georgia to accurately map bottom topography and habitat type between 2017 and 2018. Two 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 21 survey missions for all major channels and shoals where water depth exceeded 2-3 meters MLLW. Single Beam echosounder data was collected over 23 survey missions for shallow zones where water depth was below 2-3 meters MLLW.
