Cruise summary report

Cruise Info. 
Ship name (ship code)RRS Charles Darwin (74AB)
Cruise identifierCD153B
Cruise period2003-11-12 — 2003-11-27
StatusCompleted
Port of departureVictoria, Seychelles
Port of returnDurban, South Africa
PurposeResearch
ObjectivesThe 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.
