River at the Bottom of the Sea

Yellow Submarine Finds River at the Bottom of the Sea

The existence of these underwater rivers — or submarine channels — has been suspected since the 1970s, when advances in sonar technology allowed scientists to produce detailed 3-D maps of the ocean floor. Unlike ocean trenches, which are geological formations made by the movements of tectonic plates, submarine channels are created when water loaded with salt or sediment washes along and erodes the seabed. Until now, though, exactly how this dense water moves along these channels has been something of a mystery.

Got an opinion? Keep it clean. Don't ask open-ended questions, like "Does the Pope belong to a coven?" Make it pertinent.
