MOSCOW, November 18 (RAPSI) - Ekaterina Zaspa, one of the Greenpeace activists detained in Russia over an Arctic drilling protest in September, has been released on bail, Reuters reported Monday.

According to the Greenpeace website, Zaspa, 37, was a crew member from Moscow, and a “passionate environmentalist.”

Reuters reported Monday that Zaspa was found by the court to have been working as a ship medic at the time – and was not among the activists that attempted to scale the oil rig. Thus the court held that she should be released on a 2 million ruble bail.

The Arctic Sunrise ship was seized by Russian border guards on September 19 in international waters, within Russia's exclusive economic zone, a day after two Greenpeace activists scaled the Prirazlomnaya drilling rig in the Pechora Sea, the southeastern part of the Barents Sea.

The platform, owned by Gazprom Neft Shelf, a subsidiary of Russian energy giant Gazprom, is the first ice-resistant stationary oil platform in the world set to produce offshore Arctic oil.

Greenpeace and other environmental groups oppose drilling for oil in the Arctic because they say that it is currently impossible to sufficiently clean up potential oil spills in the region, and that such drilling cannot be economically viable.

On October 21, the Netherlands filed a request with the International Tribunal for the Law of the Sea to inflict interim measures which must be taken before the trial on the merits to protect the interests of the party in the dispute.
