UPDATE: Force 7 gales have forced the activists down from the rig and to safety. But the campaign continues - stay tuned.
It's the only rig on the planet that is destined to begin new deep sea drilling in the Arctic this year.
Cairn Energy's Leiv Eiriksson is on its way to Baffin Bay, Greenland, leading the new oil rush.
This morning at 5.40 local time, a handful of our volunteers intercepted the rig shortly after it left Besiktas near Istanbul in Turkey.
