| Purpose | Research |
| Objectives | This was the last of a series of three cruises in the English Channel, aimed at determining both the concentrations of biogeochemically active metals, on the individual cruises, and how they vary with the annual cycle in biological production, by comparing results from the different cruises. On each cruise, a grid of 48 stations was to be worked across the English Channel from 0 30' to 5 30'W. In addition on this, the final cruise, it was possible to occupy three stations at the shelf edge. These stations enabled pristine ocean water to be collected by the same systems as used in the Channel and should, by comparison, provide valuable information on the accuracy and precision of our measurements. In addition, a current and wave-monitoring buoy was laid. |
