Michel Viotte, with the collaboration of Olivier Dufourneaud, offers readers a wonderful journey under the ocean, a wonderful adventure in spaces that remain mysterious for many of us. An opportunity to learn more about the exploration of this dark, cold universe, with extreme pressures, but which remains populated with fascinating creatures. Abysses, l'odyssée des hommes sous la mer, is also a book that looks back at the history of the exploration of the ocean depths, and that allows us to better understand how scientists, industrialists and soldiers from France, Sweden, the United States and many other nations around the world, have been able to evolve their techniques to learn more about what happens under the sea.
