Introduction

This report collates information from the BODC cruise inventory and oceanographic databases. It presents

Cruise Inventory Information

Long name RRS Discovery (74E3) cruise D105
Short name D105
Objectives and Narrative 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.
