| Purpose | Research |
| Objectives | The four legs comprising this project were designed to extend the regional survey of the SW Approaches to the south and west of the Scilly Isles out of the Continental Shelf edge. The survey was to be carried out using shallow seismic, gravity and magnetic techniques on a skewed 7km by 12.5km grid. However, due to lack of time this programme was slightly modified. |
