Ziel der Reise / Objectives of Cruise:

The cruise P377 from Las Palmas to Las Palmas in December 2008 (08.12-22.12.2008) on board R/V Poseidon had two objectives: 1) The first objective was to investigate the water column properties along a meridional transect (22?W between 30?N to 36?N) in order to a) characterize the conditions prior to the bloom, b) localize the position of the Azores Front and c) to understand the changes in biogeochemical properties. The work along the meridional transect consisted of combined CTD (2000m) & Multi Closing Net (MCN, 100m, 700m and 2000m) stations. Samples for nutrient analysis, chlorophyll a, SPM and molecular genetics and dissolution experiments on planktic foraminifers were taken at selected depths based on the chlorophyll a-fluorescence profiles measured by means of the CTD. Additional measurements using CTD and MCN were carried out at the ESTOC station. The work is funded by the DFG through two projects (WA2157/1-1, WA2157/2-1). 2) The second aim was to carry out tests of a new technology, the so-called DNS Systems (Druckneutrale System).
