PurposeResearch
Objectives1. 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.
