Google released the first major update to its Google Earth mapping software, which will include from now on large portions of the ocean floor, allowing users to explore the sea floor terrain in 3D.

The update also includes information provided by top researchers and ocean explorers.

"You can not only zoom into whatever part of our planet's surface you wish to examine in closer detail, you can now dive into the world's ocean that covers almost three-quarters of the planet and discover new wonders that had not been accessible in previous versions," said Al Gore, who was present at the launch event in San Francisco. He added that the update transforms Google Earth into a "magical experience."

The goal for the company is to cover the entire globe as soon as possible, in order to provide its users with a complete view of our planet - offering access to the oceans’ terrain is certainly a significant step in that direction. Close to 70% of the world’s surface is covered by water, which makes it representation extremely important for any sort of map.

Looking to ensure that the best details will be provided, the update was developed in close collaboration with oceanographer Sylvia Earle and also an advisory council which included more than 25 scientists and ocean explorers.

The updates also cover other aspects, providing GPS tracking, virtual time travel and narrated tours of imagery and content. The improved software is expected to attract many new users, as it brings a fresh perspective on how to get to know our planet.
