Other ID: JD 93-1
Status: Completed
Organization(s): USGS, Woods Hole Coastal and Marine Science Center
Funding Program(s):
Principal Investigator(s): Lawrence Poppe, David Twichell
Affiliate Investigator(s): Ralph Lewis - CGS; Roman Zajac - U. New Haven
Information Specialist(s):
Data Type(s): Sonar: Sidescan, Seismics: Sub Bottom Profiler, Location-Elevation: Navigation
Scientific Purpose/Goals: Sidescan survey to determine textural distribution of surficial sediments and relate to active sedimentary processes; evaluate habitats and relate to benthic community structure. Cruise replaced cancelled ASTERIAS cruise originally scheduled for September 1993.
Vehicle(s):
Start Port/Location: Old Lyme, CT
End Port/Location: Old Lyme, CT
Start Date: 1993-11-05
End Date: 1993-11-21
Equipment Used: Klein 595 100/500kHz sidescan sonar, Q-MIPS sidescan sonar system, 3.5 kHz, DGPS, Megapulse Accufix 500 LORAN-C
Information to be Derived: Habitat maps; Sea floor map;
Summary of Activity and Data Gathered: Milford (Housatonic) and Norwalk sidescan surveys were completed. Hammonasset was postponed due to stiff, sustained southwest wind and shallow bathymetry introducing unacceptable levels of surface noise. Sidescan sonar: 450 km.
