| Objectives | The primary objective was to complete the northern portion of a circuit of tidal pressure recordings which has been determined piecemeal on a number of cruises since about 1970. The whole circuit encloses the part of the north-east Atlantic bounded in latitude by southern Iceland and Cape St. Vincent and in longitude by the mid-Atlantic ridge and west European shelf edge. The present cruise covered three deep stations near the 30° Meridian from 53.5° northward and two stations of moderate depth on the Reykjanes Ridge and the Iceland-Fareoe Rise respectively.
Leg two was used mainly by the IOS Engineering Group from Wormley to test various pieces of equipment, principally the side-scan sonar systems which were used for some geological surveying in the seas near the Hebrides. |
