| Objectives | 1. The collection of large volume water samples for analyses of selected trace metals and nutrients.
2. The collection of samples of suspended particulate material from large-volume water samples for geochemical studies. 3. The collection of integrated samples of settling particulate material by a particle trap. 4. The collection of bottom sediment samples, by gravity- and box-coring for geochemical studies. 5. The collection of a series of sediment pore water samples by in-situ techniques and by squeezing cored sediments. 6. The collection of near-surface and surface plankton samples for biochemical studies. 7. The collection of samples of the sea-surface microlayer for geochemical and biochemical studies. |
