Greenpeace activists use a modified fire pump to create a screen between the whale and the harpooner of the Yushin Maru No 2. The Arctic Sunrise is in the Southern Ocean as part of the ‘Defending Our Oceans Tour’ to document and disrupt the continued whaling in the Southern Ocean Whale Sanctuary. Greenpeace is using every available peaceful means to bring the hunt to an early end and make it the last time the Sanctuary is breached by the whalers.
