A close-up view of part of an iceberg floating in Liefdefjord on north Svalbard, weathered into strange shapes by the wind and sea. The birds perched on the top are kittiwakes. As climate change causes the Arctic sea ice to recede, the Greenpeace ship Esperanza has sailed north of Svalbard, to survey the poorly understood Arctic Ocean seabed. Meanwhile on the surface, the crew are observing and recording the diverse wildlife that has adapted to survive in this unique and harsh environment. Greenpeace is calling for the area of the Arctic Ocean historically protected year round by sea ice to be closed to all industrial activity, including destructive fishing.
