Deep-sea echinoids from the Avilés Canyons System (Cantabrian Sea: North Atlantic Ocean)
The Avilés Canyons System (ACS) is located in the South of the Bay of Biscay (Northern Spain, Cantabrian Sea) and covers a total of 3,390 km2. It is composed of three canyons, reaching the abyssal plain at 4700 m depth. The mixing of diverse water masses generates gyres and upwellings that contribut...
