Greenpeace International activists on the Greenpeace ship Rainbow Warrior have taken the first ever action at sea against companies preparing to mine the Pacific Ocean’s seabed.

A second peaceful protest also took place in San Diego’s port in the US, where Greenpeace US activists unfolded a “Stop Deep Sea Mining” banner targeting the ship chartered by another leading deep sea mining company, Global Sea Mineral Resources (GSR), from Belgium. This ship is carrying a pre-prototype mining robot for impact tests this month at depths of over 4,000m on the Pacific Ocean’s international seabed.
