Between April 15th and May 10th, 1985, Institute personnel directed and carried out an underwater archeological survey of a section of the bottom of the Ashley River and Wappoo Creek where the James Island Bridge is to be constructed (Fig.2). Two types of survey methodology were employed: electronic sensing using a side scan sonar and magnetometer, and a visual investigation of the river and creek bottom using divers. Sonar and magnetometer lines were run up and down the river over a distance of 2,000 yards, covering the impact area where the Ashley River Bridge is to be located. The diver's visual investigation was restricted to a corridor 550 feet wide by the distance across the river. This was the area to be most heavily impacted by the bridge construction activity. In Wappoo Creek, divers investigated a 300 ft corridor across the creek where a section of the bridge is to be built. No remote sensing was carried out in this area because previous channel deepening and widening in the past would have destroyed any significant cultural remains. Through analysis of the records from both electronic and diver investigations, it was determined that there were no discernible archeological or paleontological reasons to delay the construction of the bridge.
