Abstract

As part of a larger effort to examine the development and ages of paleo strand plains in northeastern South Carolina, this study uses ground penetrating radar (GPR) and LiDAR data to examine their architecture. This study builds on previously interpreted data from south of Winyah Bay with data collected from north of the Bay. GPR data was collected with a GSSI SIR-20 system and a 200 MHz antenna with an odometer wheel attached. Data locations were recorded by GPS, while elevation was extracted from LiDAR DEM data. GPR data was processed for FIR filters, range gain, stacking and surface ormalization using GSSI Radan 6x software. GPR data shows eastward dipping reflectors within the ridges, which are located on a generally seaward sloping surface. Potential divisions of these ridges may be defined by deeper dipping reflectors. Understanding the age and elevation of these paleo ridges will help to better understand past relative sea levels along this coastline.
