| Cruise identifier | D131 |
| Cruise period | 1982-08-12 — 1982-09-23 |
| Status | Completed |
| Port of departure | Gibraltar, Gibraltar |
| Port of return | Falmouth, United Kingdom |
| Purpose | Research |
| Objectives | Major objectives of the cruise were to follow up an earlier underway survey of the Charlie-Gibbs Fracture Zone with geological and geophysical station work and to sample and to make near-bottom observations of the Northwest Atlantic Mid-Ocean Canyon. The Charlie-Gibbs Fracture Zone station work was to include dredging, recordings of microseismicity and seismic refraction profiles. En route to the fracture zone a short seismic reflection profiling survey was also planned in the Iberia Abyssal Plain. |
