| Purpose | Research |
| Objectives | To determine the tidal elevations and currents in the neighbourhood of the Orkney and Shetland Islands in order to provide data for numerical models of the North Sea and Continental Shelf and to level Fair Isle to the Shetland Islands using hydrodynamical equations of motion. To determine the residual circulation of the area and distribution of temperature, salinity and density |
