Two-third of the Earth is oceans. They designated the boundaries of human knowledge. They are still a great challenge for us and the adventurous people. The exhibition looks at the great secret, this sparkling mirror, the deepest depth from a very unusual angle. We take a look inside the history of Earth, from the beginning of oceans; we adventure out to the Solar System in search of water. Finally, we return to study the oceans on a human scale. So, come with us!
