Other ID: 80-G-6A

Status: Completed

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

Funding Program(s):

Principal Investigator(s): Charles W. Holmes

Affiliate Investigator(s):

Information Specialist(s):

Data Type(s): Biological Field Study: Experiments, Location-Elevation: Navigation, Sampling: Biology, Sampling: Geology, Seismics: Sparker, Seismics: Sub Bottom Profiler

Scientific Purpose/Goals: Obtain samples of the sediments on the Mississippi-Alabama shelf, the central Tampa shelf, and the Florida Strait slope in order to confirm areas of reported phosphate concentrations. Obtain high-resolution data on the Mississippi-Alabama shelf and the southern shelf (south of 26 degrees). Obtain drill cores of the central shelf area and southern reefs. Obtain a suite of piston cores on the central shelf.
