| Purpose | Research | ||||||||
| Objectives | 1) To obtain a series of large-volume water samples, for studies of the trace element compostion and particulate matter geochemistry of some of the water masses of the North Atlantic
2) To obtain a series of sediment core samples, for geochemical sudies, along selected profiles off the North West African margin 3) To obtain samples of the benthos at 3000-4000m depth off the North West African margin. 4) To obtain a 24 hour series of biological samples from 300-600m depth at a single station off northern Spain 5) To obtain side scan sonar and telelsounder coverage of the African continental shelf | ||||||||
