Protests against Arctic drilling began in Seattle in 2015 in response to the news that the Port of Seattle authority made an agreement with Royal Dutch Shell to berth offshore drillships and semi-submersibles at the Port's Terminal 5 (T5) during the off-season of oil exploration in Alaskan waters of the Arctic. Hundreds of protesters took to Elliott Bay in kayaks, rafts, and other small boats, both as a demonstration and to interrupt docking of Shell's Polar Pioneer semi-submersible drilling vessel at Terminal 5. The waterborne demonstrators were dubbed kayaktivists by social and news media.
