Ziel der Reise / Objectives of Cruise:
The main objectives of Poseidon cruise 308 were to (1) exchange the long-term mooring K276/L1 in the Madeira Basin at 33?N, 22?W, (2) sampling the phytoplankton succession in the eastern North Atlantic and verifying 'Margalefs Mandala' as a paleoceanographic tool, (3) water sampling for Cadmium determination, and (4) sampling coccolithophores and planktic foraminifers for molecular genetic analysis. Water was sampled and temperature, salinity, oxygen concentration, and fluorescence were recorded with a CTD / rosette device. Coccolithophores and planktic foraminifers were sampled with the shipboard aquarium pump, and a 10 ?m net and a 100 ?m net, respectively. On-track sea surface temperature and salinity were measured with the shipboard thermosalinograph. Currents were registered with the ADCP system. Navigational data were provided by the shipboard navigation system.
