Ship name (ship code)RV Corystes (74RY)
Cruise identifierCOR9A/98
Cruise period1998-08-20 — 1998-09-06
StatusCompleted
Port of departureLowestoft, United Kingdom
Port of returnSwansea, United Kingdom
ObjectivesLocality: Part 1 - Thames mooring (20 - 22 August)
Part 2 - North East coast (22 - 24 August)
Part 3 - St. George's Channel and Celtic Sea (25 August - 6 September)
Part 1 was to recover a Smart Biophysical Mooring previously deployed in the Thames as part of the Climatic Status of UK Coastal waters programme.
Part 2 was 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 the 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.
Part 3 was directed at a better understanding of the dynamics of the circulation processes in the Celtic Sea/St. Georges 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 are:
1. To undertake CTD and grab surveys of the North East coast to collect information on nutrients, suspended sediment and metals.
2. To recover two moorings in the vicinity of the Thames.
3. To recover three mooring arrays in the Celtic Sea/St. George's Channel.
4. To recover free floating satellite tracked buoys in the Celtic Sea/St. George's Channel.
5. To undertake physical and chemical surveys of the Celtic Sea region.
