BOTTOM SAMPLING

Bottom samples were taken by a OCEANIC 60cm diameter box-corer. Some samples were washed and sieved on board. On 4 stations a 1.2T, 6m pipe, gravity corer was used. Table 5 shows the positioning data of the stations. The sediment recovered by the box-corer was subsampled using 4 to 6 plastic liners (80mm and 40mm diameter), that were sealed and put in refrigerator at +5  and deep-frozen at -20. Some levels were sampled on the exposed sediment column (surface, mid depth and bottom) and stored in sealed plastic bags. Photographs in Fig. 5 and following show some of the operations.
