Cruise summary report

Cruise Info. 
Ship name (ship code)RV Corystes (74RY)
Cruise identifierCOR7/98
Cruise period1998-07-03 — 1998-07-24
StatusCompleted
Port of departureLowestoft, United Kingdom
Port of returnLowestoft, United Kingdom
ObjectivesLocality: Part 1 - North East coast and Thames (approximately 03 - 10 July)
Part 2 - St. George's Channel and Celtic Sea (approximately 10 - 24 July)
Part 1 is directed at a better understanding of the dynamics of the circulation processes fringing the north 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, from previous work in the Irish Sea and limited historical data, we believe 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. In addition, several moorings in the vicinity of the Thames will be serviced as part of the Climatic Status of UK Coastal waters programme.
Part 2 is directed at a better understanding of the dynamics of the circulation processes in the Celtic Sea/St. George's Channel region. As on the north east coast, it is intended to characterise the extent and nature of the seasonal density driven circulation.
The main sampling aims of the cruise were:
1. To undertake Scanfish, CTD and grab surveys of the North East coast to collect information on nutrients, suspended sediment and metals.
2. To service two moorings in the vicinity of the Thames.
3. To deploy four mooring arrays in the Celtic Sea/St. George's Channel.
4. To deploy free floating satellite tracked buoys in the Celtic Sea/St. George's Channel in order to determine the Lagrangian circulation.
5. To undertake associated physical and chemical surveys of the region in support of 3) and 4).
