Field Activity 2007-001-FA

Identifier 2007-001-FA
Purpose Sea floor mapping (geophysics only).
Location Massachusetts Bay, Scituate, Duxbury, Massachusetts, United States, North America, North Atlantic;
Summary 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.
