Region 6: the Bay of Biscay

The area is characterised by multiple oceanographic processes, such as slope currents, upwelling-downwelling processes, river plumes and various types of eddy-like structures. It supports a high diversity of PETS, including high levels of common dolphin (Delphinus delphis), the bycatch of which is of particular concern, with France and Spain having legal obligation under EU law to adopt conservation measures to stop this bycatch. The innovative tools being developed here will help to address both local issues and be applicable to other regions.
