Google Earth 5.0, which was released on Monday, lets users travel underwater to see the sea floor. It also lets them travel back in time to see earlier versions of the service's aerial and satellite photography.
No longer is the ocean floor simply a blob of blue. You can now fly under the surface and see subsurface ridges and landmarks like this underwater mountain range off the coast of Hawaii.
Through a partnership with the BBC, various footage from the Planet Earth television series is available for watching right in Google Earth, including this clip of sea urchins scouring the sea floor for food.
