The Center for Marine and Wetland Studies (CMWS) at Coastal Carolina University (CCU) has conducted geophysical mapping to delineate hardbottom areas and to identify possible cultural resources in the proposed Charleston Harbor entrance channel extension and improvement areas of the navigation channel. Data consisting of side scan sonar, sub-bottom profiles, magnetics, and single beam bathymetry were collected between October and December, 2012. Following initial examination of the geophysical data records, groundtruthing was conducted in late 2012 and early 2013. A combination of geophysical data, sediment grabs, and video tows revealed areas of known, probable, and possible hard bottom throughout the study area.
