Ziel der Reise / Objectives of Cruise:
The "Extended Ellett Line" Scotland - Rockall - Iceland Time Series The objectives of the cruise were to 1. To observe water mass properties, the instantaneous velocity field and subsequently the heat and salt (fresh water) fluxes between the subpolar gyre and the Nordic Seas in 2004. 2. To compare the 2004 conditions with those observed in the previous years (to 1975 in the Rockall Trough, 1988 in the Iceland Basin), quantifying the interannual to decadal changes in properties and understanding the causal mechanisms of variability. 3. To enhance the physical and tracer measurements with biological observations to investigate nutrient cycling, export production, ecosystem structure and dynamics.
