RRS Charles Darwin CD153B
Cruise summary report
Cruise Info. | |
Ship name (ship code) | RRS Charles Darwin (74AB) |
Cruise identifier | CD153B |
Cruise period | 2003-11-12 — 2003-11-27 |
Status | Completed |
Port of departure | Victoria, Seychelles |
Port of return | Durban, South Africa |
Purpose | Research |
Objectives | The goal of CD153B was 1) to start long-term monitoring of the currents, some hydrographic properties, organic contaminants and vertical particle fluxes at the narrowest section of the Mozambique Channel 2) to obtain detailed information on the hydrography along this section 3) to obtain information on the sediment biogeochemistry along the western side of the channel. |
