ObjectivesThe primary objective was to complete the northern portion of a circuit of tidal pressure recordings. The circuit encloses the part of the northeast Atlantic bounded in latitude by southern Iceand and Cape St Vincent and in longitude by the mid-Atlantic ridge.

The circuit was steamed in an anticlockwise direction. Sounding and magnetometer watches continued for most of the deep water passage work. Exact repetition of Leg 1 course was avoided. Tide gauge capsules were released and recovered and good records were obtained. Stong magnetic anomalies were observed when passing the top of Reykjanes Ridge.
