The present ocean is thermally stratified. The waters become colder with depth, and the great mass of ocean deep water is near 2°C-almost the same as that of surface waters in the polar regions. The idea that the waters have a polar origin goes back to Benjamin Thompson (1800)(Count Rumford). He reasoned that the cold waters of the interior of the ocean must form by sinking in the polar regions and must drive poleward flow of surface waters. The idea was refined by Alexander von Humboldt(1814), who noted that the density of sinking cold polar waters must exceed the density of more saline waters in lower latitudes.
