Ziel der Reise / Objectives of Cruise:
The main objective of the cruise was to: a) perform the second mapping of the tracer CF3SF5 that was injected in late 2012 (MSm23) near the OMZ at around 10?N 21?W and about 500 meters depth; b) map the water mass, oxygen and transient tracer distribution by the CTDs and glider; c) determine the synoptic ocean circulation and mixing by S-ADCP observations, as well as glider based microstructure measurement; d) determine biogeochemical rates of oxygen consumption and nutrient cycling by zooplankton studies, nitrogen fixation experiments and two drifting sediment trap experiments. A gilder was released at 17?26'N and 24?30'W. Sampled a low oxygen eddy at 19? 02'N and 24? 46'W with ten CTD stations followed by a full ocean depth CTD at the Cape Verde Ocean Observatory (CVOO). A glider was recovered at 16?N 33' and 20?W 03' on March 21 Between March 22 and the end of the cruise tracer was samples in a grid between 19?W and 25?W and 8?N and 12?N. On some stations biogeochemical parameter are sampled and a plankton net is taken. A drifting sediment-trap mooring was released at 10?N and 21?W and at 10? 15'N and 21?W and recovered them roughly a week later. The last glider was deployed at 10? 38'N and 21? 30'W. The last CTD station was taken at 8?N and 25?W in the evening of April 14.
