One phenomenon experienced when descending a deep mine shaft is that the deeper you go, the hotter it gets. This also applies to oceanic crust. Oceanic rift zones extend over a length of some 40,000 miles (~60,000 km) and host a guesstimated 2-3 million volcanic vents, black smokers and methane seeps. The sun is not the only agency responsible for heating water and driving the thermo-haline conveyor belt.
The single loop of 1,000 years only replaces 1/3rd of the deep ocean water. It takes 3,300 years (3 loops) to replace all of the deep ocean water with water that was once in the surface mixed layer (top 2.4% over that 3,300 years.

planning to do oceanography for uni, this is very helpful and interesting!
