Puncak Jaya

Also known as Mount Carstensz, in the Sudirman Range of New Guinea (Indonesia). It is the highest island peak in the world.

It once held glaciers almost on the equator, but by 2025 more than 99% of that ice had melted. Mainland Australia's highest point, Mount Kosciuszko, is only 2,228 m.

Flat map of Earth with the oceans drained: the dry seafloor in sand to deep red-brown around green continents.

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.
