This is Earth with all of its ocean water removed: the mid-ocean ridges, deep trenches and underwater mountain ranges that normally hide under an average of 3.7 km of 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.
