gear, a tether ball system (visual) , or both. Additionally, voice communi- 

 cation with the submersible via acoustic telephone was maintained at all 

 times. Launch and retrieval of the submersible was accomplished without 

 difficulty in sea conditions ranging from sea state 1 to 5 . 



Navigation to the submersible station locations was accomplished with 

 Loran C; a radar reflector buoy was placed at each appropriate location 

 and the submersible location was tracked and plotted from radar ranges and 

 relative bearings to the station buoy. Census of the megabenthic invertebrates 

 consisted of 2 half-mile transects at constant depth during which time the 

 scientific observer in the submersible visually counted and voice recorded 

 on magnetic tape invertebrates and associated demersal fishes seen within 

 a prescribed path between the keel of the submersible and a tickler chain 

 suspended from a yardarm mounted on the bowplane of the submersible. 

 Representative pictures of the bottom community were recorded on video tape. 

 Color still-photographs further documented species composition and 

 deportment . 

 LOBSTER POTTING OPERATIONS 



The lobster-potting vessels, Mars and Crystal-S , operated in the 

 Veatch Canyon area during the period June 4-11 (Mars) and June 13-19 

 (Crystal-S) . Six trawl strings of about seventy lobster pots each were 

 fished as a part of the survey; three strings were hauled each day thus 

 giving a two-day soak time per string. The catch of lobsters, crabs, 

 and fish were weighed, measured, and sexed.
