Purpose | Research |
Objectives | The primary objective of the cruise was to take samples of the air/sea interface, near surface water, the sediment/water interface and deeper sediment from selected water columns in the Gulf of Guinea. It was planned to work mainly over local high spots both in the basin area and on the banks. From experience this gives the best chance of collecting sediments in their original time sequence. We wished to test our hypothesis that this is a suitably pure marine area of high productivity, free from significant terrigenous input, for detailed geochemical study of diagenetic processes.
The secondary objective was to examine the distribution of mid-water organisms in the area, and take good quality live plankton sample for subsequent shipboard biochemical/physiological experiments. It was hoped that the area would be rich enough to allow short duration net hauls, and together with the new cod-end system, allow the collection of good experimental material. |
