These are the two most important regions where salty, dense bottom water forms, powering ocean currents thousands of miles up and downstream.

The current thought as to how the deep ocean is warming is because formation of the coldest bottom water around the Antarctic is slowing down, being replaced by «warm» water from the North Atlantic.

This zone is suspected to be due to a combination of factors, most importantly, from acids produced when bottom water rich in toxic hydrogen sulfide gets mixed upward.

Periodically, parts of the south coast experience local, wind - driven upwelling of cool bottom water, while the fast flow of the current itself drives upwelling of deep waters, where the shelf widens to form the Agulhas Bank [11].

Presently, much of the Atlantic Ocean is well oxygenated (Figure 1) relative to the North Indian and Pacific Oceans, where bottom water O2 concentrations are lower because of the biological removal of O2 as thermohaline circulation moves deep waters across ocean basins from the North and South Atlantic towards the North Pacific, in isolation from the surface ocean.

According to the results presented here, the production of dense bottom water in the North Atlantic makes it possible for an Atlantic overturning to exist, but southern hemisphere winds appear to determine the magnitude of the inflow and outflow.
