Cruise Inventory Information
| Long name | RRS Discovery (74E3) cruise D342 |
|---|---|
| Short name | D342 |
| Objectives and Narrative |
Site survey work (shallow seismic survey and gravity core sampling) at 16 sites of proposed drilling in the North Atlantic (Irish and UK waters). Additional seismic work and sampling in the area was undertaken, details below.
Gravity and magnetic data were recorded during seismic surveys and also over 4 transects across the Rockall Trough and Rockall Hatton Basin. |
