XBT probes were ‘fired’ during the second leg of the cruise when the vessel was [...] mixing at the surface decreases the oxygenation of the lower water masses. Additionally, it decreases the formation of central water, which is subducted from the thermocline. In the case of SACW, the formation [...] deoxygenation of the water mass. This can greatly impact the ventilation of the surrounding water body and the formation rate of the water mass itself. Consequences are the expansion and formation of oxygen minimum
