Beaufort Sea

Chevron Corp has put a plan to drill for oil in the Beaufort Sea in Canada's Arctic on hold indefinitely, while Marathon Oil cut its capital expenditure for next year by about 20 per cent.

Ruby Kaleak's part-time job on polar bear patrol in the village of Kaktovik, Alaska, usually means chasing the animals back to the Beaufort Sea. But she wasn't expecting to shoo one of the biggest bears she's ever seen out of a house last week.

US researchers have measured swells of more than 16 feet in once frozen region of Arctic Ocean that have the potential to break up ice even faster, threatening an "ice-free summer" that could have potentially wide-ranging implications.
