to the North Atlantic Gulf Stream. May be it does a similar job too, only upside down of course.
A deep ocean current with a volume equivalent to 40 Amazon Rivers has been discovered by Japanese and Australian scientists near the Kerguelen plateau, in the Indian Ocean sector of the Southern Ocean, 4,200 kilometres south-west of Perth.
In a paper published in Nature Geoscience, the researchers described the current -more than three kilometres below the Ocean's surface -- as an important pathway in a global network of ocean currents that influence climate patterns.
"The current carries dense, oxygen-rich water that sinks near Antarctica to the deep ocean basins further north," says co-author Dr Steve Rintoul from the Antarctic Climate and Ecosystems CRC and CSIRO's Wealth from Oceans Flagship.
"Without this supply of Antarctic water, the deepest levels of the ocean would have little oxygen.
So how does THIS affect global warming? Anyone know? As I have said before, there's a lot we don't know.
