Ziel der Reise / Objectives of Cruise:
Cruise M160 (MOSES Eddy Study II) carried out a detailed high-resolution, multi-parameter study of individual eddies. Eddies are an omnipresent feature and the likelihood of encountering individual eddies during the timeframe and in the working area of the cruise is very high. Eddies are generated off West Africa throughout the year with a peak in frequency during summer. At an average propagation speed of 3.0?2.5 km/day along their typical westward trajectories this peak in eddy abundance has reached the region to the northeast of the Cabo Verdean archipelago by November/December. This time window therefore provided the highest likelihood for encountering strong eddies in the working area, the extension of which is constrained by the operation range of the Stemme S10 VTX motorglider (Aachen University of Applied Sciences) used for parallel airborne observations of sub-mesoscale eddy features. The ambitious eddy study followed an approach demonstrated successfully during the 2014 "Eddy Hunt Project" (GEOMAR & Kiel University) combined with the successful approaches of the sub-mesoscale experiments SubEx I and II and the "Expedition Clockwork Ocean" (HZG). Using refined and proven automated detection methods employing remote sensing products (sea level anomaly, sea surface temperature, ocean colour) early detection of eddies was possible during the months preceeding the cruise. For groundtruthing of potential candidate eddies, ocean gliders were deployed from the "Ocean Science Centre Mindelo" (www.oscm.cv, S?o Vincente island, Cabo Verde) prior to the cruise. Two gliders carrying an extended sensor suite (CTD, oxygen, chlorophyll, turbidity) were steered towards the candidate eddies for a remote hydrographic survey. Two cyclonic eddies were selected for detailed study during M160.
