USGS Coastal and Marine Geology Program

Coastal & Marine Geology Program

Field Activity Details for field activity 1999-026-FA

Other ID: MD 99-02; IMAGES V, Leg 1

Status: Completed

Organization(s): USGS, Woods Hole Coastal and Marine Science Center

Funding Program(s):

Location: Chesapeake Bay, United States, North America, North Atlantic;

Principal Investigator(s): John Bratton, Stephen Colman

Affiliate Investigator(s): Tom Cronin - USGS, Reston; Peter Vogt - Naval Research Lab; Jeff Halka - MD GS

Information Specialist(s):

Data Type(s): Location-Elevation: Navigation, Sampling: Chemistry, Sampling: Geology

Scientific Purpose/Goals: Conduct an interdisciplinary study of Holocene paleoclimate and ecosystem history, methanogenesis, and geological evolution of modern Chesapeake Bay. To accomplish these goals, collect long piston cores (>20 meters) from the mesohaline portion of Chesapeake Bay.

Vehicle(s):

Start Date: 1999-06-20

Start Port/Location: Norfolk, VA

End Date: 1999-06-29

End Port/Location: Quebec City, Quebec, Canada

Equipment Used: Calypso corer, GPS (wh), Water sampler

Information to be Derived:

Summary of Activity and Data Gathered: Coring exercises collected 6 cores at 5 sites (approx. 68 m of sediments); digital core photos; spectrophotometry; pore water samples; radiocarbon samples; and MST logging (magnetics, gamma and p-wave).
