Exploring the oceans to better understand life in the universe

Published 2026-10-30

In an interview with Ouest-France, David Wahl explains that exploring the oceans can change our view of Earth's place in the cosmos. According to him, studying the seas and seabeds helps us understand that life is not necessarily a unique phenomenon. He recalls that the ocean remains largely unknown, even though it covers the majority of our planet's surface.

The researcher points out that extreme marine environments, such as hydrothermal vents located at great depths, are home to organisms capable of surviving without sunlight and with very little oxygen. These discoveries interest scientists who are seeking to determine whether forms of life could exist elsewhere in the solar system, particularly beneath the icy surface of certain moons. For David Wahl, this research shows that the conditions necessary for life are sometimes more varied than previously thought.

This work also directly concerns France, which has one of the largest maritime areas in the world thanks to its overseas territories. Knowledge of the oceans is therefore important for protecting biodiversity, managing resources and combating climate change. The scientist stresses the need to continue exploration missions in order to better understand these still poorly known environments.

In conclusion, David Wahl's interview shows that the study of marine depths does not only serve to better understand the Earth. It also raises questions about the origin of life and the possibility of living presence beyond our planet.
