Ziel der Reise / Objectives of Cruise:

The aims of the cruise P349 from Las Palmas to Funchal in April 2007 (05.04-24.04.2007) on board of R/V Poseidon were: 1) the recovery of the Kiel276-25 (33?N, 22?W), 2) the deployment of Kiel276-26 and 3) the investigation of water column properties along two meridional transects (22?W & 20?W from 30?N to 40?N) in order to localise the position of the Azores Front and understand the changes in biogeochemical properties. Additional measurements using CTD and MSN were carried out at the ESTOC station. The work along both meridional transects consisted of combined CTD (2000m) & MSN (100m, 700m and 2000m) stations. Samples for nutrient analysis, chlorophyll a, coccolithophores biomass and foraminifera genetics were be taken at selected depths based on the chlorophyll a-fluorescence profiles measured by means of the CTD. The work is funded by the DFG trough two projects The mooring Kiel276-25 was successfully recovered on 10th of April, and the mooring Kiel276-26 was deployed on 17th April 2007 for the duration of two years. The station work was succesfully carried out; two stations were not occupied because of bad weather.
