ObjectivesThe principal objective of the cruise was to prove age of a number of apparently linked sedimentary rock basins in the area west of Orkney and the north end of the Minch. A secondary objective was to establish the nature of the unconsolidated sediments resting on rockhead and to compare these to known deposits on land. In the event of bad weather it was planned to investigate the surficial sediments to the west and north of N Rona and the extent of the sand wave fields at the western end of the Pentland Firth. In practice, however, drilling operations were carried out throughout the cruise and little time was available for other work.
