ObjectivesThe purpose of the cruise was to confirm the solid geological interpretation of the East Shetland area by use of shallow drilling techniques. The drilling involved the use of the Bradford Institute of Oceanography (B.I.O) Drill and the Institute of Geological Sciences (I.G.S) 1m rock drill.

The East Shetland area (Fig.1) defined between latitudes 60°N and 61°N and longitudes 0°W and 1°W, was selected because of the excellent control provided by previous IGS geophysical surveys (Briarthorn Cruise 74/4) and the presence of abundant near surface outcrops ideally suited for sampling by the above methods.

Evaluation by IGS and IKU (Norway) of the new developments of the Bradford Institute Drill, initiated following the participation by D.A. Ardus in BIO drill operations in 1975, was also a prime cruise objective.
