Ziel der Reise / Objectives of Cruise:

Cruise P293/2 was aimed to study the variability of the overflow through Denmark Strait and to serve time series station southeast of Greenland. The overflow through Denmark Strait is one major component to form North Atlantic Deep Water (NADW) and thus plays an essential role in the world-wide thermohaline circulation. Within the "Sonderforschungsbereich 460" of the German reseach foundation (DFG), the dynamics of its variability is investigated using direct measurements of currents and heights of sea surface and overflow layer at the sill depth, and the height of the reservoir in terms of temperature north of the sill. During the cruise, hydrographic observations with CTD and vADCP were to be obtained south the sill, across the sill and north of the sill. Within the EU-funded project ANIMATE, one of three open ocean time series stations was to be implemented southeast of Greenland in the Central Irminger Sea (CIS). The station is equipped with recently developed sensors to measure CO2-flux, the contents of nutrients, and fluorescence as parameter for chlorophyll a in the upper 10 m to 90 m. Also, an inductive-modem based under-water data transfer and a small surface buoy is used to transmit near-real-time data of temperature and salinity from the upper 1000 m through satellite for open use (http://www.soc.soton.ac.uk/animate/main/home.php). As a service for the Plymouth Marine Laboratory, a continuously recording plankton recorder was to be towed whie steaming
