Ziel der Reise / Objectives of Cruise:

POS533-2: The Poseidon cruise POS533/2 was part of the observational program of the TRR181, an interdisciplinary research program of the Deutsche Forschungsgemeinschaft (DFG). The overarching aim of the TRR181 ?Energy transfers in atmosphere and ocean' is the energetically consistent representation of the oceanic and atmospheric energy cycles in climate models. After POS516 (2017) and POS523 (2018) the cruise POS533/2 was the third expedition to the area south of the Azores within the TRR181. South of the Azores seamounts generate very energetic internal tides which radiate energy towards the Cap Verde Islands. During POS516 and POS523 we conducted a spatial survey to better understand the fluxes and dissipation of the internal tides. A mooring measuring time series of temperature and current velocities was redeployed at 30?29'N, 30?12'W during POS523 in May 2018. Its data will be used to study the temporal variability in the energy of the internal tides. With the successful retrieval of this mooring, the goal of POS533/2 was fully achieved.
