Cruise summary report
| Cruise Info. | |
| Ship name (ship code) | RRS Charles Darwin (74AB) |
| Cruise identifier | CD112C |
| Cruise period | 1998-05-20 — 1998-06-24 |
| Status | Completed |
| Port of departure | Fairlie, United Kingdom |
| Port of return | Fairlie, United Kingdom |
| Purpose | Research |
| Objectives | Seafloor environment assessment and specifically to:
1) Carry out a large-scale seafloor sampling programme in selected deep-water areas (17th round Tranches) to the north and west of Scotland. The sampling to be guided by a survey design promulgated in advance of the cruise and modified on the basis of field observations and sidescan sonar interpretations of the survey areas to be received during the course of the cruise. 2) Similarly carry out photographic surveys in the same area. 3) Repeat seafloor sampling of 15 sites on a bathymetric transect west of Shetland, previously sample during RRS Charles Darwin cruise 101C leg 2 (Atlantic Margin Environmental Survey 1996). |
