Field Activity Details for field activity 2004-002-FA

Other ID: none

Status: Completed

Organization(s): USGS, Woods Hole Coastal and Marine Science Center

Funding Program(s):

Principal Investigator(s): Bradford Butman, Jane Denny

Affiliate Investigator(s): MA CZM

Information Specialist(s): Brian Andrews

Data Type(s): Imagery: Photo, Imagery: Video, Location-Elevation: Navigation, Sampling: Geology, Seismics: Sub Bottom Profiler, Sonar: Interferometric, Sonar: Multibeam

Scientific Purpose/Goals: 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.


Start Date: 2004-04-12

Start Port/Location: Gloucester, MA

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).

Staff: Seth Ackerman, Brian Andrews, Dann Blackwood, William Danforth, Jane Denny, Barry Irwin, Katherine McMullen, Charles Worley
