Summary Information for Field Activity 1986-022-FA

Area of Operations: central Chesapeake Bay, United States, North America, North Atlantic

Dates: September 22, 1986 to October 03, 1986

Chief scientist: Steve Colman

   Jeff Halka, MGS; Woody Hobbs, VIMS

Objectives: Collection of high-resolution seismic reflection and sidescan sonar data in order to define the geology and shallow structure of the Chesapeake Bay.

Type of Activity: Seismic profiling; Sea floor mapping;Sea floor mapping

Information to be derived: High-resolution seismic reflection and sidescan sonar data

Summary: 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.
