Deep water The circulation of the oceans is driven by two main factors: winds and the formation of deep water («deep water» is ocean water that is more than about 1500 meters below the surface).
-LSB-... * Salinity in the sea fell sharply during the Permian for the first time, changing oceanic physics to
make deep water circulation more difficult.
Oceanographically, the Southern Ocean is a major driver of global ocean circulation and plays a vital role in interacting with
the deep water circulation in each of the Pacific, Atlantic, and Indian oceans.
