"The WWF contracted RPS Applied Science Associates to model 22 different oil spill scenarios and map the spread of the oil, potential impact on the water and shoreline, and interaction with sea ice, wildlife and the surrounding ecology.
Types of oil spills analyzed included shipping spills, shallow-water blowouts and deep-water blowouts. The BP Plc Macondo oil well rupture in 2010 that unleashed more than four million barrels of oil into the Gulf of Mexico was a deep-water blowout.
The remote Beaufort Sea is a section of the Arctic Ocean that spans the Canada-U.S. border. It comprises about 476,000 square kilometres (184,000 square miles) off the northern coasts of Alaska, and Canada's Yukon and Northwest territories, and until recently was packed with sea ice even in summer."
