Between 400 and 1200 m depth, in total darkness, we find unique ecosystems ever filmed. Scientists knew the existence of these ecosystems and their associated species due to coring sediment and fauna, but never been able to watch them directly on its environment.
Off the coast of Cadiz and Huelva, methane emissions are the engine of a unique ecosystem, consisting of a large number of species that directly or indirectly benefit from these emissions. During the last campaign of the group of Marine Geosciences (GEMAR) belonging to the Spanish Institute of Oceanography (IEO), under the LIFE + INDEMARES project, were filmed for the first time different types of habitats and species of these ecosystems. Some species may be new to science or never before mentioned in this part of the Atlantic.
Now scientists work overtime, analyzing images and the collected samples, hoping that their findings would make the change necessary to safeguard these deep ecosystems of the Gulf of Cadiz
