ObjectivesTo study the relationships between physical and biological parameters in the southern North Sea, Lyme Bay and Skagerrak. The sea surface termperature, salinity, chlorophyll 'a', suspended solids and nutrients are planned to be monitored continuously. Vertical profiling to be done on station with the STD + hose and whilst underway with XBT's and the undulating CTD (batfish) + oxygen sensor + in situ fluorometer. Current measuements will be carried out at the southern end of the Dogger Bank using moorings 059 and 060.
