A huge underwater plateau in the remote southern Indian Ocean, built by massive volcanic eruptions, mostly between about 110 and 85 million years ago. Only a few peaks, like the Kerguelen and Heard islands, still break the surface.
Ocean drilling found wood, a seed, spores and pollen in 90-million-year-old sediment here: parts of the plateau were once dry land with plants.
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.
