The Antarctic Slope Current near 30 degrees E
The Antarctic Slope Current flows westward above the continental slope of Antarctica, entering the Weddell Sea near 30 degrees E and supplying dense water to the deep overturning cell there, and contributing to global Antarctic Bottom Water formation. Observations from the 2008 I6S hydrographic sect...

A prominent topographic feature, the Gunnerus Bank, diverts the Slope Current upstream of this longitude, and has a large effect on the current's structure, splitting it into a coastal and offshore component.
