Cruise summary report

Cruise Info. 
Ship name (ship code)RV Corystes (74RY)
Cruise identifierCOR7/00
Cruise period2000-05-18 — 2000-05-25
StatusCompleted
Port of departureLowestoft, United Kingdom
Port of returnLowestoft, United Kingdom
ObjectivesThis was the fourth in a series of cruises planned to investigate the processes that influence productivity and the distribution and behaviour of suspended particulate matter and nutrients in the southern North Sea. The transport of nutrients and particulate matter from UK waters to the southern North Sea and European coastal zone is especially of interest.
1) To service the Smart Buoy and mini-pod moorings deployed during March in the Sean Gas Field and at the Outer Gabbard;
2) To deploy ADCP and current meter moorings in the vicinity of the Sean gas Field Smart Buoy;
3) To collect water samples and CTD profiles;
4) To complete Scanfish surveys;
5) To deploy satellite-tracked drifting buoys.
