Two Greenpeace vessels, the MV Greenpeace and the Twister, spent two weeks using Remotely Operated Vehicle (ROV) to survey the seabed at depths up to 100 meters in the Hurd Deep, in UK territorial waters just off the Channel Islands and some 15km north-west of Cap de La Hague (France). It shows corroding, broken and disintegrated barrels of radioactive waste, remnants of some 28,500 barrels tipped into the sea by the UK between 1950 and 1963. Hurd Deep is one of many such dumpsites used until a global ban was agreed in 1993.
