Other ID: Cruise J-143 II; JSL dives 1233-1241
Organization(s): USGS, Woods Hole Coastal and Marine Science Center
Principal Investigator(s): David Twichell
Affiliate Investigator(s): Robert Jones - Harbor Branch Foundation; Churchill Grimes - Rutgers Univ.
Data Type(s): Sonar: Sidescan, Seismics: Sub Bottom Profiler, Location-Elevation: Navigation
Scientific Purpose/Goals: Assess the importance of erosion by biological organisms on the outer continental shelf around the head of Hudson Canyon by surveying tilefish burrows via sidescan sonar (distribution mapping) and submersible observation.
Start Port/Location: Woods Hole, MA
End Port/Location: Cape May, NJ
Start Date: 1982-07-22
End Date: 1982-07-29
Equipment Used: Klein 531 sidescan, ORE 140 transceiver/1036 transducer sub-bottom profiler, Northstar 6000 LORAN-C
Information to be Derived:
Summary of Activity and Data Gathered: Seismic survey equipment deployed and recovered at multiple locations. Sidescan survey data collected and observations in JOHNSON SEA-LINK noted. Data collected include video, still photos, audio transcripts, temperature data, current data, 3.5 kHz profiles, and sidescan sonar profiles.
