PurposeResearch
Objectives1. Study and quantify the circulation of the region of the Atlantic north and east of 42N, 20W and south of 53N, with a box of full-depth CTD casts; sampling to include CTDO measurements together with fluorescence and transmittance profiles, and salinity, oxygen and nutrients from Niskin bottles. The pattern of CTD and SeaSoar measurements to closely follow the track of Cruise 181, 12 months earlier.
2. Continue a programme of SeaSoar development by means of trial deployments involving a package of sensors mounted on the towed vehicle.
3. Survey the interior of the box of CTD stations using SeaSoar, to quantify the T/S characteristics of recently-ventilated Mode water.
4. Make underway ADCP measurements throughout the cruise.
5. Make underway analysis of non-toxic pumped seawater supply using thermosalinograph and fluorometer.
6. Occupy a grid of CTD stations in the Bay of Biscay east of 10W, as part of the GASTOM experiment.
7. Test a modification to a piece of coring equipment for IOSDL..
