Armed Danish commandoes are thought to have been landed on a giant oil rig by helicopter to prevent environmentalists interfering with a British oil company's controversial exploration of deep Arctic waters. In a stand-off in the Davis Strait, west of Greenland, the Danish navy has been shadowing the Greenpeace ship Esperanza as it tracked the 53,000 tonne Leiv Eiriksson in iceberg-strewn sea to the site where it plans to search for oil at depths of up to 5,000ft.
The confrontation between Denmark and Greenpeace, which argues that it is dangerous to drill for oil in pristine Arctic waters, follows the decision by Scottish oil company Cairn Energy to explore for oil and gas in Baffin Sea this summer.
Fears that an Arctic spill would be difficult if not impossible to clean up were confirmed in an email exchange between the British Foreign Office and the energy secretary, Chris Huhne, that was obtained by Greenpeace under freedom of information legislation. Officials briefed Huhne, saying: "It is difficult to get assistance in case of pollution problems in such areas, and near impossible to make good damage caused."
They warned of "significant" environmental challenges and the potential for a Gulf of Mexico-type spill. "The impact of such a spill in the Arctic would be proportionately higher due to the lower temperatures and (in winter) lack of sunlight that will inhibit oil eating bacteria (which played a large role in cleaning up the Macondo spill). The Arctic ecosystem is particularly vulnerable, and emergency responses would be slower and harder than the Gulf of Mexico due to the areas remoteness and the difficulty of operating in sub-zero temperatures. A situation compounded by response lag resulting from the vast distances between points of habitations and at certain times, winter ice."
