This image made available by environmental organization Greenpeace shows Greenpeace activists chained to the anchor chain of the Anna Akhmatova, the vessel which was carrying Gazprom's workers to the Prirazlomnaya platform, in the Pechora Sea about 620 miles (1,000 kilometers) from the nearest port, Murmansk, a city on the extreme northwestern edge of the Russian mainland, Monday Aug. 27, 2012. Gazprom is pioneering Russia's oil drilling in the Arctic. The state-owned company installed the platform there last year and is preparing to drill the first well. Environmentalists have warned that drilling in the Russian Arctic could have disastrous consequences because of a lack of technology to deal with a possible spill in this remote region.
