Information to be Derived:
Summary of Activity and Data Gathered: Two ships were used for this cruise: R/V DAN MOORE (Cape Fear Tech) for first week; R/V DISCOVERY (MGS) for second week of survey. Cooperators: Virginia Institute of Marine Science (VIMS), Maryland Geological Survey (MGS), and Cape Fear Tech. All equipment performed extremely well with the exception of the sidescan sonar system which failed completely on the first day due to a cable break. Seismic reflection records collected and very good except for areas that contained biogenic gas. Records clearly show entire quaternary and upper part of the Tertiary sequence of deposits. Cruise completed the basic seismic reflection grid between mouth of the bay and the Patuxent River begun by earlier two cruises.
