Field Activity Details for field activity 1985-017-FA

Other ID: none

Status: Completed

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

Funding Program(s):

Principal Investigator(s): Edward Escowitz

Affiliate Investigator(s):

Information Specialist(s):

Data Type(s): Sampling: Geology, Sampling: Biology, Sonar: Single Beam, Location-Elevation: Navigation

Scientific Purpose/Goals: Delineation of placer heavy minerals in a number of study areas. Follow-up sampling of areas previously sampled.


Start Port/Location: Fort Lauderdale, FL

End Port/Location: Alexandria, VA

Start Date: 1985-06-03

End Date: 1985-06-28

Equipment Used: Alpine Vibracorer, Box corer, Grab sampler, Echosounder, Sidescan sonar, Loran-C, Magnavox satellite positioning system

Information to be Derived:

Summary of Activity and Data Gathered: A total of 60 vibracores and 72 grab samples were acquired. The majority of the grab samples were processed at sea using the three-turn spiral to concentrate the heavy minerals. Selected grab samples were examined microscopically to determine the major constituents of the heavy-mineral assemblages present.
