Cruise period1999-07-19 — 1999-08-04
StatusCompleted
Port of departureLowestoft, United Kingdom
Port of returnLowestoft, United Kingdom
ObjectivesThe work is directed at a better understanding of the dynamics of the circulation processes fringing the northeast 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.
The main sampling aims of the cruise are:
1. To recover five mooring arrays laid during Corystes 5/99 in the vicinity of the Dogger Bank.
2. Recover free floating satellite tracked buoys deployed during Corystes 5/99. A number may be deployed and recovered during this cruise.
3. To undertake Scanfish, CTD and grab surveys of the neartheast coast and Dogger Bank to collect information on nutrients, suspended sediment and metals.
4. Conduct experiments to examine the near-bed cross frontal circulation.
