Ziel der Reise / Objectives of Cruise:

The overflow through the Denmark Strait is one of the major sources 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 Research Foundation (DFG), the dynamics of its variability and interaction with overlying water masses is investigated. In Denmark Strait, direct measurements of currents in the overflow layer at the sill were performed as one component of the project. During cruise P293-2 in 2002, a shielded ADCP was moored on the western shelf; this ADCP could not be recovered due to a technical problem one year later during cruise P302. Therefore, during P315 an attempt was made, to recover the ADCP using a small ROV of the MARUM, University of Bremen. Cruise P315 (maps in Fig 3.1 and 3.2) was aimed to - recover the shielded ADCP moored during POSEIDON cruise 293/2 in 2002 and which could not be recovered during cruise P302 in 2003 - to recover and re-moor an ADCP of the MRI in Denmark Strait - to take some CTD casts and ADCP sections across the sill when restricted time allows.
