RRS Charles Darwin CD134
Cruise summary report
| Cruise Info. | |
| Ship name (ship code) | RRS Charles Darwin (74AB) |
| Cruise identifier | CD134 |
| Cruise period | 2001-10-10 — 2001-10-17 |
| Status | Completed |
| Port of departure | Victoria, Seychelles |
| Port of return | Victoria, Seychelles |
| Purpose | Research |
| Objectives | The principal objectives were:
1. to obtain a swath bathymetric chart of the region to identify seafloor fabric over the continental margin, 2. to identify basement outcrops that could provide targets for dredging in 2003 to determine the nature of the acoustic basement, 3. to obtain magnetic profiles normal to the margin which could be interpreted in terms of the extensional history of the margin and fill gaps in the existing track coverage, 4. to delimit the trend of the oldest seafloor spreading anomaly (anomaly 27) in a region where it appears to be offset by a possible fracture zone. |
