Information Specialist(s):

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

Scientific Purpose/Goals: The main purpose was to complete bottom sediment sampling in the nothern quadrangle and to do additional 3.5 kHz seismic profiling as a supplement to those taken in earlier cruises of the GOSNOLD and VERRILL last year.

Vehicle(s):

Start Port/Location: Woods Hole, MA

End Port/Location: Woods Hole, MA

Start Date: 1970-06-10

End Date: 1970-06-16

Equipment Used: Van Veen grab sampler, Dietz-Lafond snapper, Grab sampler, ORE 140 transceiver/1036 transducer sub-bottom profiler, Echosounder, Loran-A, Visual navigation, Raytheon radar

Information to be Derived: Grain size analysis;

Summary of Activity and Data Gathered: A total of 154 stations were occupied during the seven days at sea. The GOSNOLD steamed a total of 691 miles during which we obtained approximately 600 miles of sonic profiles. Samples were taken 2-4 miles apart and were selected utilizing a 1/40,000 scale bathymetric map of the sea floor compiled by the Coast & Geodetic Survey. Selection was key to a variety of topographic features in the area, some only a few hundred meters across. Despite very complex topography, the type of sediment was restricted to relatively few types - broadly outlining topographic provinces rather than particular features. Sonic profiles showed penetration 20 fms over soft bottom and a multilayered arrangement of reflecting horizons over basins. Some of the reflectors appear to pinch out toward the basin edge or to have an erosional pinch out at the edge.
