Status: Completed

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

Funding Program(s):

Principal Investigator(s): Peter Popenoe

Affiliate Investigator(s): Frank Manheim; Vernon J. Henry - Georgia State U.

Information Specialist(s):

Data Type(s): Imagery: Photo, Imagery: Video, Location-Elevation: Navigation, Sampling: Geology

Scientific Purpose/Goals: 80 miles east of Charleston: 1. To establish stratigraphic age, lithology, and phosphorite content of strata by bottom sampling of outcrop areas. 2. To determine the nature of scarps. To observe and measure fracture patterns and possible scour and bioerosion features. 3. To observe and record phosphorite pavement thickness and extent and presence and thickness of manganese rinds. 4. To assess the benthic ecology of the study area, with particular emphasis on sessile epifauna. 5. To record current directions and speed with time. 6. To observe and record nepheloid layers, acoustic scattering and other organisms in the water column, and other water column parameters.
