End Date: 2004-05-07
End Port/Location: Gloucester, MA
Equipment Used: SubX swath bathymetry, Camera- deep sea, Video camera - deep sea, Digital camera, Real Time Kinematic GPS, Grab sampler - Van Veen , Knudsen CHIRP Sub-bottom Profiler
Information to be Derived: Grain size analysis; Habitat maps; Sea floor map; Bathymetric maps; Morphology;
Summary of Activity and Data Gathered: 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).
