Summary for Field Activity Number 1983-004-FA

Alternate Leg ID: AST 83-04

Area of Operations: Cape May, New Jersey, Northern Delmarva Peninsula, United States, North America, North Atlantic

Dates: June 21, 1983 to July 02, 1983

Objectives: Survey examples of bottom morphology off Cape May, New Jersey and, using a small vibracorer and Van Veen grab, sample these for possible heavy mineral accumulations in order to determine possible correlations of such accumulations with morphology and shallow stratigraphy.

Type of Activity: Sampling

Information to be derived: Samples and chemical analysis
Morphology

Summary: Tested vibracorer rig; determined maximum depth limit was about 70 feet. Sidescan sonar was tested and produced records of doubtful usefulness. On subsequent days we alternated Uniboom surveys with days of sampling. Navigation for the cruise was by LORAN-C which was recorded on cassette tapes. Tape #1 malfunctioned at an point, so some of the navigation data is probably absent. The paper printout was retained so the data is retrievable. All Uniboom data was recorded on analog magnetic tape as well as on paper. Andrew Grosz returned to Reston, VA via truck carrying the cores and samples obtained with him. Uniboom lines: 13 (174 km); Sidescan sonar lines: 1 (20 km); Stations: 37; Vibracores: 16; Van Veen grab samples: 35.
