The National Oceanic and Atmospheric Administration vessel Thomas Jefferson has sailed from Norfolk, Va., and will use sonar to attempt to locate the wreck about 75 miles off Cape May.
A remotely operated vehicle will be sent down to capture images.
The Coast Guard says the survey will help identify the condition of the vessel and any contributing factors that lead to the sinking.
Officials have postponed an April 6 hearing into the sinking until the survey results are analyzed.
