The Greenpeace ship MY Esperanza maintains position off the shoreline of Kongsfjord, while helping with the installation of marine science equipment. Small mountains still holding snow, visible in the background. The Esperanza and its crew are working with scientists from the German marine research institute IFM-GEOMAR to investigate ocean acidification, by deploying nine large "mesocosms" (experiment water enclosures) in Kongsfjord, near the Arctic scientific research station of Ny-Alesund.
