Gouf de Capbreton
The biological richness of the Capbreton gouf is above all a consequence of its geological structure. It is one of the deepest submarine canyons in the world. It sinks to a depth of 3,500 meters and its length reaches 270 kilometers. Its size is close to the size of the Grand Canyon of Colorado.
Le Gouf de Capbreton was born in the structural history of the Bay of Biscay and the Pyrenees. It opened during the phase of expansion from the Iberian Peninsula to Europe and the integration phase that followed.
Several species of higher predators are regularly present on or around the Capbreton gouf. The frequentation by cetaceans and seabirds is strong and regular, throughout the year.
