Abstract:

In June 1999, a cultural resources remote-sensing survey was conducted in the approximately 5,000-acre Ocean Dredged Material Disposal Site ODMDS of the Mississippi River Gulf Outlet MRGO located near Breton Island just northeast of the entrance to the Mississippi River in Plaquemines Parish, Louisiana. The purpose of the survey was to locate historic shipwrecks or other underwater cultural resources that may exist in the project area. The remote-sensing survey located a number of magnetometer and side-scan sonar targets. The vast majority of these are related to identifiable oil and gas structures, such as pipelines and well sites, or to trash and debris, such as pieces of pipe and cable. Six targets exhibited some of the magnetic andor side-scan sonar characteristics of known historic shipwrecks. These targets were examined in more detail and all but one are believed to be related to modern debris. The source of the one target could not be ascertained with the available data and it is recommended that it be identified through diver examination.
