Current which flows along continental slope that brings nutrient rich water from the Arctic.

The
Zhemchug Canyon is located in the middle of the Bering Sea, between Siberia and Alaska. It has a vertical relief of 8,530 feet or 2,600 meters dropping from the shallow shelf of the Bering Sea to the depths of the
