Somewhere in the North Atlantic, more than a kilometre beneath its surface, a cold-water coral reef stretches across an unnamed seamount. Despite never appearing on a chart, this underwater forest has existed for centuries, growing a centimetre or two each year.
The reef is a home and feeding ground for dozens of species that depend on it the way a woodland creature depends on trees. It has survived ice ages – but whether it will survive increasing pressures from industrial fishing, deep-sea mining and climate change is, in part, a question about data. If we don’t know it exists, how can we protect it?
