| Purpose | Research |
| Objectives | The aims of this section of the programme were twofold. The first objective was to survey seven proposed borehole sites with sparker and pinger. These sites were to the north-west of Scilly and formed part of the Sealab drilling programme. The second objective was a regional marine geophysical survey of the 1:250000 Scilly sheet, which would include the use of gravity meter, magnetometer, sparker, pinger and sonar. In order to achieve this a BP single scan sonar was placed on board. The Institute's Klein dual scan sonar was on board as back-up. |
