Challenger Deep
The deepest known point in the ocean, at the southern end of the Mariana Trench in the western Pacific. It lies about 10,935 m below sea level; measuring it precisely is hard simply because it is so deep.
Drop Mount Everest (8,849 m) in here and its summit would still sit about 2 km under water.
Pull the plug and watch the sea level fall, explore the seafloor as real terrain, find what lies off your own coast, and follow guided stories, from the Ice Age land bridge between England and France to the wreck of the Titanic. Everything is built from GEBCO's grid of the world's ocean floor and land.
