ObjectivesThe work is directed at a better understanding of the dynamics of the circulation processes fringing thecnorth east coast of England, between the Firth of Forth and Flamborough Head, and in vicinity of the Dogger Bank. It is intended to characterise the extent and nature of the density driven and seasonal jet like circulation which acts as a direct and rapid pathway for transport of material from the coastal region to the central North Sea. Subsequently, the knowledge will be viewed with respect to concerns that elevated levels of contaminants on the Dogger Bank have originated in the near coastal region. Additionally, work includes the servicing of a mooring in the vicinity of the Outer Gabbard as part of the National Marine Monitoring Programme.
The main sampling aims of the cruise are:
1. To service a smart mooring at the Outer Gabbard.
2. To deploy five mooring arrays in the vicinity of the Dogger Bank.
3. Deploy free floating satellite tracked buoys in order to determine the Lagrangian circulation. Subsequently, a number may be retrieved.
4. To undertake Scanfish, CTD and grab surveys of the north-east coast and Dogger Bank to collect information on nutrients, suspended sediment and metals.
5. Conduct experiments to examine the near-bed cross frontal circulation.
