Field Activity 1982-026-FA

Identifier 1982-026-FA
Alternate names Cruise J-143 II; JSL dives 1233-1241
Purpose 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.
Location Hudson Canyon, North Atlantic continental shelf, United States, North America, North Atlantic;
Summary 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.
