What Would a Trip to the Mariana Trench Be Like?

Using data from NASA, NOAA, and other research institutes, a British scientist has produced a high-definition animation that reveals what Earth would look like if all of the planet's oceans disappeared.

If the Earth bears the nickname of "blue planet" it is not for nothing. It is enough to take a little height to see that blue indeed occupies a major place on our planet. A color that of course corresponds to that of the oceans and for good reason, the latter occupy more than 70% of the earth's surface or some 360 ​​million square kilometers.

This surface is now divided into five oceans and dozens of seas which play essential roles. They are home to much of Earth's biodiversity, regulate the climate, release most of the oxygen we breathe, and provide vital resources to billions of people around the world. But what would Earth look like if the oceans disappeared?

This is revealed by an animation published on the internet by Dr. James O'Donoghue, a former NASA scientist who now works for JAXA, the Japanese space agency. The high definition footage is an update of an animation produced by the same researcher in 2008 using data from NASA, NOAA, and other research institutes.
