Submarine canyons

Submarine canyons are recognized as ecological hotspots on continental margins, providing a number of services to ecosystems and humans. In the Mediterranean sea, canyons are particularly threaten by cumulated anthropogenic impacts and climate change effects (including changes in deep water convection and extreme meteorological events). Several of these canyons were recently highlighted to host abundant populations of deep-sea corals and may display even higher vulnerability, as thcanyon lacaze duthiersese ecosystem engineers are particularly sensible to warming and acidification of deep waters.

Despite recent efforts in seabed mapping and dedicated physical oceanography monitoring, constrained access to these marine habitats, which requires the use of ROVs or manned submersibles, largely limited the capacity to acquire basic knowledge on ecosystem dynamics. The complex links between environmental fluctuations and ecosystem functions therefore remains largely unknown. There is thus a critical need to fill these gaps in order to understand how climate forcing may challenge ecosystem stability.
