Polluting shipwrecks are a ticking time-bomb at the bottom of our oceans

The Hindu  

At the bottom of the oceans and seas lie more than 8,500 shipwrecks from two world wars. Of course, wrecks from the world wars are far from the only ones to be found at the bottom of the sea, with many others adding to the problem. Many of the wrecks that may pose the greatest problems are found in shallower coastal waters, where government mapping initiatives and work by industry provide much higher resolutions, yet still the challenge of identification remains. This is placed in stark relief by the work of British maritime archaeologist Innes McCartney and oceanographer Mike Roberts, whose detailed geophysical and archival investigations in the Irish Sea demonstrated that historic wrecks have been frequently misattributed and mislocated. Advances in subsea drones known as Autonomous Underwater Vehicles, which are fitted with an array of sensors to measure the seabed and detect pollutants, could help enhance our knowledge about the locations of wrecks, what they’re carrying and their state of deterioration.
