CTD sections were designed to enable the ocean circulation in the Subpolar gyre of the North Atlantic to be mapped and in particular the course of the North Atlantic Current branches. The main goal is to continue annual monitoring of the North Atlantic large-scale circulation and climate changes in the North Atlantic started in 1997. The Denmark Strait Experiment II was the second part of 7- day experiment carried out in July 2018. It was designed to understand the mechanisms of short-term variability of water exchange between the North Atlantic and the Nordic Seas.
