The Arctic-bound vessel got through after police intervened, arresting campaigners. All protesters were eventually lowered into Willamette River by the Coast Guard, Oregon State Police and Portland Fire & Rescue crews and detained for alleged criminal trespassing and interfering with law enforcement, according to reports. After the human blockade was removed and the icebreaker, which is central to Royal Dutch Shell’s plans for extracting oil in the Arctic, began to depart, so-called “kayaktivists” tried to engage the vessel by rowing into its path. Greenpeace claimed the action was a success. “We found that the blockade was successful." Nicole added that the goal is to bring attention to the issue and persuade President Barack Obama to reconsider giving permission to Shell to drill in the Arctic.
