Diver at Gray's Reef National Marine Sanctuary, Georgia Bight

Dr. Ervan Garrison, of the University of Georgia, will undertake a study of submerged prehistoric archaeological sites drowned after the end of the Last Glacial Maximum (LGM). The sites are expected to be found on the Atlantic Ocean’s Continental Shelf of the Georgia Bight. Such sites are difficult to discover and study but are extremely relevant to understanding human entry adaptations in the Americas. Dr. Garrison’s research seeks to develop a new method of underwater survey designed to overcome many of the costs and difficulties currently associated with underwater archaeological exploration. His study will exploit existing erosional features are created around wrecks or artificial reefs. These exposures are compelling targets for archaeological testing because excavation has already been done by natural forces such as tidal currents. A successful study of scour nuclei offers us the ability to advance our understanding of the now drowned southeastern coastal plain along the Atlantic. This study will seek to improve current methodologies for survey and recovery of submerged archaeological sites.
