Over the last 14 months, most of the 16 U.S. intelligence agencies have assigned analysts to work full time on the Arctic. The Office of the Director of National Intelligence recently convened a "strategy board" to bring the analysts together to share their findings.
In addition to relying on U.S. spy satellites orbiting overhead and Navy sensors deep in the frigid waters, the analysts process raw intelligence from a recently overhauled Canadian listening post near the North Pole and a Norwegian surveillance ship called the Marjata, which is now being upgraded at a U.S. Navy shipyard in southern Virginia.
