Field Activity Details for field activity 1994-026-FA

Other ID: 94-3

Status: Completed

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

Funding Program(s):

Principal Investigator(s): Richard Rendigs, Harley J. Knebel

Affiliate Investigator(s):

Information Specialist(s):

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

Scientific Purpose/Goals: Sidescan sonar and 3.5 kHz survey (reconnaissance) and sediment sampling (if time permits).


Start Date: 1994-06-20

Start Port/Location: Sandwich, MA

End Date: 1994-06-29

End Port/Location: Plymouth, MA

Equipment Used: DGPS, Klein 531 sidescan, Q-MIPS sidescan sonar system, 3.5 kHz, Grab sampler - Van Veen

Information to be Derived: Grain size analysis; Habitat maps; Sea floor map; Bathymetric maps; Morphology;

Summary of Activity and Data Gathered: Sidescan sonar: 445 km; 3.5 kHz Seismic: 445 km; Total 26 transects; No samples attempted. The cruise was very successful in accomplishing about 95 percent of the original expectations for total trackline coverage. Data quality was excellent and the records clearly displayed areas of high and low backscatter which will be useful for extending a sedimentary environments map southward from its present extent in Massachusetts Bay. The 3.5 kHz echo sounder was an excellent companion piece of equipment for detailing the shallow sub-bottom stratigraphy as the reflector's position relative to the surface of the sea floor is a useful adjunct for interpreting sidescan sonar records.

Notes: The cruise heeds to the requests of a pre-cruise report dated 12/9/93. Cruise will not interfere with the WHITEHEATH cruise departing June 6, 1994, as Rick Rendigs is the Chief Scientist on both.
