Ziel der Reise / Objectives of Cruise:

The research cruise of RV POSEIDON to the Nordic Seas during summer 2012 was used to pursue and complete ongoing research in the Nordic Seas. The main goals of the research cruise were a large-scale hydrographic CTD survey along 75?N through the Greenland Sea (station distance 10 nm) and, embedded into this section, a mesoscale hydrographic survey across the Polar Front with the Underway-CTD (station distance 2 nm). The Greenland Sea is one of the few regions in the high latitudes were deep reaching convection during winter takes place. From 1993 to 2010 the 75?N section through the Greenland Sea was carried out every summer. Our CTD survey continued these observations and enables us to observe the long-term development of hydrography in the area. For the water mass transformation within the Greenland Sea the lateral exchange between inner basin and boundary current is of crucial importance. The exchange across the Polar Front is meant to be managed by mesoscale eddies. These structures were insufficiently observed in the past. Now insight is given by the high-resolution UCTD survey. Additionally two Argo-floats were deployed in the Greenland Sea Basin and Lofoten Basin to maintain the large-scale monitoring of the Nordic Seas. On the east Greenland shelf a mooring array was planned to be recovered, if ice-conditions are favourable. The cruise was also used as practical education for three students of physical oceanography at the University of Hamburg.
