Purpose | Research | ||||||||||||
Objectives | 1. Continued benthic and midwater sampling in the Porcupine Sea Bight area for comparison with data gained on previous cruises.
2. A day and night vertical series of midwater hauls for S.M.B.A biologists at their routine benthic sampling station in the Rockall Trough. 3. A series of oblique midwater hauls along the 13W or 17W meridian to investigate the influence of the Mediterranean outflow and the delineation of zoogeographic boundaries. 4. A transect of benthic sledge tows out from the continental shelf of North West Africa to abyssal plain depths. 5. A survey of any fronts encountered in the Porcupine Sea Bight area. 6. Midwater hauls using the low level photometer to fish specific isolumes. | ||||||||||||
