The cruise addressed objectives of the work package ‘Physical drivers’ (Research Focus 1), focusing on ocean mixing and water transformation process studies in the region east of Svalbard, with particular focus on the Barents Sea Polar Front region.

The cruise was conducted from RV G.O. Sars. The study region covered 24-35˚E and 75-79˚N, and the purpose of the cruise was to deploy moorings for process studies (1 year duration), carry out maintenance service and redeploy accessible gateway moorings (long term), deploy underwater gliders (cruise duration as well as 3-4 months missions), conduct ocean mixing and water transformation process studies in the Barents Sea Polar Front region east of Svalbard, and sample for biology, nutrients and the carbonate chemistry in the water column at selected stations.
