Dates: April 12, 2004 to May 07, 2004
Chief scientist: Brad Butman
Objectives: Phase I - Complete geophysical mapping of the South Essex Sanctuary (Gloucester to Nahant; 40 m to 10 m water depth). Phase II - Conduct ground validation survey of 100 target stations in the survey area.
Type of Activity: Sampling; Seismic profiling; Sea floor mapping; Photography;Sea floor mapping
Information to be derived: Grain size analysis; Habitat maps; Sea floor map; Bathymetric maps; Morphology;
Summary: Phase I Geophysical Survey: 8 total survey days with Submetrix, Knudsen, EdgeTech. Lost 5 days to rebuilding starboard engine on RAFAEL. Data collected: Submetrix bathymetry/backscatter, EdgeTech sidescan, Knudsen seismic reflection. Phase II Ground Validation: Occupied 100 target stations in 3 survey days, recovered 56 sediment samples. Data collected: bottom video, bottom stills, sediment samples (grain size).
