Ziel der Reise / Objectives of Cruise:

The cruise took place in Fram Strait in the northern part of the Nordic Seas to carry out physical and biological oceanography investigations as tem. Work was done along a section at about 79?N between Spitsbergen and Greenland, at the western slope of the Yermak Plateau, in the Molloy Deep and at a site east of Molloy Deep whi TO000" d which is used as "AWI-Hausgarten" since then. To quantify the inter-annual to decadal variation of volume, heat and salt fluxes through Fram Strait, an array of moorings is maintained since 1997 to measure currents, temperature and salinity. The year-round measurements are combined with hydrographic sections taken during the cruises. Until 2005 the observations were done in the framework of the European Union projects 'VEINS' (Variability of Exchanges in Northern Seas, 1997-2000) and 'ASOF-N` (Arctic-Subarctic Ocean Fluxes, 2002-2005). At present the work is part of the EU Integrated Project `DAMOCLES` (Developing Arctic Modeling and Observing Capabilities for Long-term Environmental Studies). It is associated to the international Arctic-wide study `ASOF`. The cruise started in Longyearbyen at August 20th, 2006 afternoon. Several parts of the deck gear did not work then but the continuation of repairs was postponed to the next port call in Reykjavik. The working area in Fram Strait was reached in the following night and the first CTD-casts along a strait-wide hydrographical section at 78?50`N were taken. At all casts a lowered ADCP was attached to the CTD/rosette for velocity measurements. In the morning of August 21st we returned eastwards and tried to recover the first mooring F3-8 (Fig.1). Acoustic interrogation failed to evoke a response from either the transponder at the top of the mooring or the bottom releasers and also after a "blind" release the mooring did not surface. After this disappointing start we continued eastwards and successfully recovered moorings F2-9, F1-8 and a PIES (Pressure Inverted Echo Sounder). Due to the malfunction of the 20-t-beam all mooring w
