Underwater Cultural Resources Survey for Contraction Dikes at Red Eye Crossing, Mississippi River, Baton Rouge to the Gulf of Mexico, Louisiana
Abstract
A magnetic and acoustic remote sensing survey for submerged cultural resources was conducted in the Mississippi River south of Baton Rouge, Louisiana, between River Miles 223.3 and 224.7-L. The project area encompasses the proposed site of a series of six dike structures to be built to maintain the depth of the navigation channel at Red Eye Crossing M-224 AHP. The survey was conducted for the U.S. Army Corps of Engineers, New Orleans District, pursuant to Delivery Order 0001 of Contract Number DACW29-92-D-0011. A controlled hydrographic survey was performed over the 285.1-ac project area utilizing a proton precession magnetometer to collect magnetic data, a side-scan sonar to record acoustic anomalies, and a precision echosounder to acquire bathymetry. Real time positioning was maintained by a Differential Global Positioning System (DGPS) linked to a computer navigation program. Sixty-eight magnetic anomalies were recorded during the survey. On target, which was associated with a cluster of magnetic anomalies and an acoustic anomaly, appears to be the remains of a spud barge lost in 1979. A second cluster of anomalies is associated with an acoustic image of the wreck of a wooden hulled vessel.
