Objectives | The aims of this cruise were fourfold with the main priority being to carry out a regional shallow seismic survey on a 5km grid between 61°N and 1°E to the median line. The second priority was a detailed area within this grid where 1km grid spacing was to be employed. The information required for this detailed area was in the first 100 metres of sediment. This area was of particular interest to Shell and Esso who had representatives on board for part of the cruise. The other objectives were to collect data along the Brent pipeline from the edge of the 1974 East Shetland survey area (see MGU Report No 54) to the main survey area, and to survey three profiles using the 12 channel digital recording system in an area north of Unst for IGS Hydrocarbon Group. |
