Greenock, United Kingdom — We've set sail with the Scottish Association for Marine Science (SAMS) to explore one of the oldest and least understood habitats on Earth. Using remotely operated vehicles (ROVs) - small, unmanned submarines - scientists onboard the Greenpeace ship Esperanza will study, sample and document the fascinating underwater world off the coast of Scotland.

The expedition to the Mingulay reef, located in around 150m of water off the west coast of Scotland, will provide vital scientific data on one of the biggest cold-water coral reef complexes so far discovered in UK waters.  

During the expedition, which set off from Greenock, near Glasgow, on 12 May, scientists will also be looking for any evidence of damage to the reef. Although the extent of any damage to the Mingulay reef is currently unknown, coral habitats around the world face many threats - particularly from destructive fishing practices such as bottom trawling.

Bottom trawlers drag heavily weighted fishing nets across the seabed - effectively steamrolling the ocean floor and smashing everything in the way.

Bottom trawling is the number one threat to fragile cold-water coral structures, which provide habitats for a diverse range of species including fish, sponges, starfish, sea urchins and crustaceans.  Lophelia reefs also serve as important fish spawning and nursery grounds. It takes one year for Lophelia to grow 2.5cm. It takes just one typical fishing trip for a bottom trawler to sweep approximately 33 square kilometres of the seabed.

We are calling for a moratorium on high seas bottom trawling to protect ocean life.
