Researcher in the Deep Environment Laboratory at Ifremer
The abyssal plains lie some 5,000 kilometres from the surface and are extreme environments where no light penetrates and therefore difficult to explore.
However, new technologies are making more things possible. Since 2020, France has had one of the four AUVs in the world capable of diving to a depth of 6,000 metres.
Seabed observatories also exist to provide a maximum of information to researchers.
There are both autonomous and cabled ones.
The aim today is to learn more about the underwater fauna and flora. In the samples taken from the abyssal plains, 90% of the species found are unknown.
Anaïs Marechal has a PhD in Geoscience. She first became interested in earthquakes, which she studied in research laboratories and in the field for several years. In 2017, she decided to train in science journalism at ESJ Lille. Since then, she has been working as a freelance journalist for various general, specialised and professional print media where she covers climate, health and new technologies.
