Thousands of shipwrecks lie on the United Kingdom seabed, most of them forgotten and still shadowy.
A marine archaeologist said as these wrecks degrade “you could have the equivalent of a small oil tanker running aground,” but the only way to find out what threat they pose is to survey all the ships and re-identify them, says Dr Michael Roberts, from Bangor
Without knowing the cargo, experts say there is no way to know what threat they pose as they degrade. As climate change increases storms and water temperature, metal tankers are breaking down faster.
