Physical oceanography and ADCP measurements during Maria S. Merian cruise MSM15/4

Data from cruises carried out in recent years now indicate that the process of deep water formation has again been reversed, with Adriatic deep water being the main source for the deep water formation. The reversal of deep water production in the Ionian Sea is a long-term process and therefore it needs to be monitored over a period of years.

The characteristics which are crucial for the deep water today, how it differs from the deep water before the EMT and in which state of the reversal it resides, these are the questions which have to be investigated continuously during the coming years. The cruises which have been accomplished (such as POS298, M71/3, MSM13/2) and the current one shall fulfill this purpose.
