Information Specialist(s): Seth Ackerman, Brian Andrews
Data Type(s): Location-Elevation: Navigation, Seismics: Sub Bottom Profiler, Sonar: Multibeam, Sonar: Sidescan
Scientific Purpose/Goals: Sea floor mapping (geophysics only).
Start Port/Location: Green Harbor, MA
End Port/Location: Green Harbor, MA
Start Date: 2007-04-20
End Date: 2007-05-04
Equipment Used: SWATHplus-M 234 kHz, Real Time Kinematic GPS, Submetrix Sidescan sonar, EdgeTech 424 chirp sub-bottom profiler, Klein 595 100/500kHz sidescan sonar
Information to be Derived: Sea floor map; Bathymetric maps;
Summary of Activity and Data Gathered: Completed mapping in shallow water along coast, approx. from Green Harbor to Scituate, to fill in areas not covered by 2006 Megan Miller survey. Collected full coverage bathymetry and backscatter data, and closely spaced grid of sub-bottom profiles. Cruise was delayed 6 days by a strong nor'easter. Lost several days at end of cruise due to weather. Took along two data processors on this cruise for the first time (usually only one) in order to speed up the production. New 4-stroke outboards performed well, very quiet and lots of power. Auto-pilot seldom deviated from programmed HYPACK lines. New pole mount for chirp worked great, allowed tight turns to port w/out prop damage to fish. Now, if we could just find a way to launch/recover the big 512i fish! Total trackline length = 525 km; area mapped = 57 km2; water depths range from 4-20 m. Nearshore area south of Green Harbor (off Duxbury Beach) was not completed due to weather; will fill gaps during July cruise.
