The Zhemchug Canyon
The largest and deepest submarine canyon on record is the Zhemchug Canyon; it lies right in the middle of the Bering Sea. The canyon goes 2,000 meters deep, making it deeper than the Grand Canyon.
The Zhemchug Canyon is also the largest submarine canyon based on drainage area as it covers 11,350 km of deep, oxygen-rich waters that enter the canyon and provide sustenance to the different life forms and creatures that exist there. Each of the two main branches of the Zhemchug Canyon is larger than regular continental canyons.
