Objectives1) Participation in an international survey of pelagic 0-group gadoids in the North Sea
2) Studies on the timing of recruitment of gadoids to the demersal phase
3) Collection of live fish for the aquarium
4) A sample of cod were deep frozen for the Lowestoft Laboratory
5) 4 samples of surface water collected along the edge of the Norwegian Deeps were brought back for the Woods Holes Laboratory

A relief engineer and a member of scientific staff joined the ship at Lerwick on the 26/06/1978. A mid-trip call was made at Cristiansand from the 03/07/1978 till the 04/07/1978. The pelagic trawl was damaged which meant that it was not possible to make hauls on the sea bed to study the recruitment of gadoids to the demersal phase.
