PALEOTEMPESTOLOGY UPON THE SOUTH CAROLINA COASTLINE: A CALIBRATION OF THE SEDIMENTARY HISTORICAL RECORD
Ten vibra- and push cores from Middleton Pond contain sands that vary from fine to medium in grain size and range in color from tan to dark gray. There are three visible events in which sands abruptly contact lacustrine sediments, indicating either hurricane or storm activity. Deeper within the cores, oysters shells suggest that these sediments may have experienced a marine versus freshwater environment as well. Six cores from Moccasin Pond also contain several visible sand layers apparently deposited from lateral storm flooding via an inlet from the northwest. The lower portions of these cores are similar to those of Middleton Pond with the exception that no oyster shells are present. Future analyses include radioisotope age-dating and micro-scale image analysis using the Pierre Francus method in order to determine smaller scale structures resulting from flooding and overwash events.
