Cruise Inventory Information

Long name RV Cefas Endeavour (74E9) cruise 12/04
Short name 12/04
Objectives and Narrative The project is generally aimed at achieving a better understanding of the dynamics of the circulation processes of the seas around the UK. In order to characterise the extent and nature of density driven and seasonal jet-like circulation which acts as a direct and rapid pathway for transport of material.
This cruise and the previous Corystes 13/04 and following Endeavour 14/04 cruises are targeted to describe the gradual (September - November) alteration of pathways as frontal regions move and revert to the fully mixed and largely wind driven winter regime. The chosen area of interest is the Northern flank of the Dogger Bank along a line that was previously visited in June and August 1999, 2000 and in 2001.
The structure of the mixing in the bottom region, and for comparisons with models, a thermistor chain and ADCPS will be deployed for the period between the cruises, this will enable the exact timing and nature of breakdown to be indentified.
As well as the thermohaline structure the phtyo plankton structure and nutrient uptake will be investigated. With regular samples taken for Isotope analysis.
Oxygen measurements will also be undertaken in the Oyster grounds region.
The main sampling aims of the cruise are:
1. To characterise the hydrographic structure associated with the frontal regions and investigate the transport pathways. By use of towed undulating CTDs.
2. Deploy ARGOS drifting buoys to quantify the Lagrangian circulation.
3. Recover and redeploy Mooring (ADCP and thermistor chain) to study the mixing processes in the transistional region.
4. Conduct experiments for phtyoplankton production both by Nitrogen uptake method and by Carbon14 labelling.
5. Take samples for Isotope analysis.
