Crew on MY Esperanza in Jamaica

The Greenpeace ship MY Esperanza is in the Atlantic Ocean during the "Lost City" leg of the Protect Our Oceans tour, an almost year-long pole to pole voyage from the Arctic to the Antarctic – to highlight the many threats facing the oceans and to campaign for a Global Ocean Treaty covering all seas outside of national waters.
The Lost City (or Lost City Vent Field) is a series of alkaline hydrothermal vents located in the Mid-Atlantic ocean.
