PurposeResearch
ObjectivesThe goal of this D289B cruise was 1) to extend the dataset on long-term observations on the currents, some hydrographic properties and settling particle fluxes at the narrowest section of the Mozambique Channel from an array of moorings 2) to obtain detailed information on the hydrography along this section 3) to further assess the sediment biogeochemistry along the western side of the channel and 4) to obtain sediment cores for accessing the geological archive using pistoncoring on the western slope of the channel.
