PurposeResearch
ObjectivesJC088 was the second of two cruises under the NERC-funded Consortium grant FASTNEt (Fluxes Across the Sloping Topography of the North East Atlantic). Sailing 08:30 BST on Friday 28th June 2013 from King George V Dock, Govan, JC088 was a 26 day cruise to the Malin Shelf edge, returning to Southampton at 08:30 on Wednesday 24th July 2013.

The scientific aims for JC088 were three-fold:
1) A process study of the internal tide and its contribution to cross shelf exchange and vertical mixing
2) An investigation of on-shelf intrusions of high-salinity water of oceanic origin
3) deployment of long term platforms (Drifters and Gliders) for an investigation of the state of exchange at the shelf edge during the transition from summer-stratified to winter well-mixed conditions.
