Ziel der Reise / Objectives of Cruise:

The Azores Front with the associated Azores Current forms the northern boundary of the subtropical gyre in the eastern North Atlantic, not only for physical properties but also for plankton species which abundance very much depends on the nitrogen budget. The cruise had two major objectives: (i) to exchange moored current meters and particle traps near the front at site KIEL276, 33?N, 022?W to extend the long time that has been obtained at this site since 1980, and (ii) to monitor plankton communities. To achieve the goals, mooring V276-24 was recovered after one year of recording time and mooring V276-25 launched for scheduled two years at 33?N, 022?W. Several CTD/rosette and several multinet stations were obtained across the front between 31?N, 023?W and 35.5?N, 022?W, and samples from the uppermost sediment stratus were taken at 3 sites.
