The ROV (ROUV, Remotely operated underwater vehicle) is lowered into the Water from on Bord the Esperanza. The Vehicle is launched into the UK Part of the North Sea to investigate a methane leak at the Seabed. Activists on board the Greenpeace ship Esperanza documented two large methane leaks located in the British exclusive economic zone (at positions 57°55.30'N, 001°37.87'E and 57°54.81'N, 001°38.72'E) in the North Sea. Caused by a major blow-out incident during a gas drilling operation 30 years ago, the leak is still emitting the highly potent greenhouse gas methane.
