It is the largest submarine canyon in Europe, reaching depths of about 5,000 metres (16,000 ft) and a length of about 230 kilometres (140 mi). The canyon is being studied as part of the EU HERMES project using a remotely operated vehicle. The project is investigating the specialized canyon ecosystems, sediment transport and deposition, and the way in which the canyon influences and is affected by local ocean circulation.
