Here currents and upwelling interact to produce a highly productive area, termed the Green Belt, that supports an abundance of fishes and squids as well as birds and marine mammals.

Bottom trawling fishing boats have devastated many cold water coral reefs along the margin of the North East Atlantic Ocean. Now, researchers have found large cold water coral colonies clinging to the vertical and overhanging sides of submarine canyons 1350 metres below the surface of the Bay of Biscay.

Deep-sea corals area among the most vulnerable ecosystems and the United Nations has called for their protection. Most of these interesting communities have disappeared from large extensions of European waters and the Mediterranean due to bottom trawling, changes in water temperature or natural catastrophic events.
