The water mass transformation in the Southern Ocean plays a crucial role for the global overturning circulation. In this study, the northward flowing water masses from the Drake Passage to the tropics have been studied using Lagrangian trajectories. The water masses increase in temperature and salinity along these pathways. Previous studies have speculated that these changes are mainly due to air-sea interactions. However, we show that internal mixing plays a crucial role. Further, we reveal five distinct pathways from the Drake Passage to the tropics, and show where the waters are changing their properties.
