After this two-month Arctic Under Pressure ship expedition ended, Greenpeace renewed its calls for urgent climate action and an immediate moratorium on industrial activities in the Arctic region. During the expedition, the Greenpeace ship Esperanza examined some of the threats facing fragile Arctic Ocean ecosystems. As well as capturing breathtaking images and footage of previously unseen areas of the sea floor north of Svalbard, the expedition supported groundbreaking research into the effects of ocean acidification caused by CO2 pollution.
