Cruise summary report
| Cruise Info. | |
| Ship name (ship code) | RRS Charles Darwin (74AB) |
| Cruise identifier | CD109 |
| Cruise period | 1997-10-25 — 1997-11-19 |
| Status | Completed |
| Port of departure | Lisbon, Portugal |
| Port of return | Lisbon, Portugal |
| Purpose | Research |
| Objectives | 1. Estimation of the total mass of selected landslide features and 3-dimensional visualization.
2. Evaluation of size and frequency of large landslides off the islands and seamounts of the NW African volcanic province and estimation of the risk for the coastal population of the Canary and Madeira Islands and NW Africa due to tsunamis triggered by such mass wasting events. 3. High resolution compositional temporal, structural and sedimentological analysis of a large volcaniclastic apron surrounding an intraplate volcanic island system and of the more distal abyssal plain sediments. 4. Calculation of sediment budgets for the growth, evolution and unroofing of the volcanic edifices of the area. |
