Abstract:

The objective of the seismic reflection and side scan sonar survey is to determine the location, aerial extent, and depth of burial pits situated along the reservoir bottom of L lake, Savannah River Site, SC. The results will be used in the overall characterization of L lake by providing continuous profile line coverage of the boflom and subbottom sediment structure along the entire length of the project area. The results are also intended to supplement previous scientific information obtained from soil samples, aerial photography, and radiometric studies. Resultant information will be used as input for an Environmental Impact Statement of the site. Overall, the seismic reflection data will provide a better description of variations in the actual subbottom conditions and help identify differing sediment layers. The side scan sonar will aid in identifying the location of burial pits and any other features on the bottom of the reservoir. A 3.5 kilohertz kllz, high resolution subbottom profiling system and an EGG Model 260 side scan sonar system were used to meet the primary objectives of the investigation.
