About 80 miles off the Virginia coast, the Continental Shelf drops off from a depth of 600 feet to sink thousands of feet more toward the black bottom of the deep ocean.

The shelf stretches north to Canada, and carved all along its slope are great undersea canyons - some 100 miles or longer, and deeper than the Grand Canyon. Twilight worlds that scientists say have gone largely unexplored, unappreciated and misunderstood.
