Study of northern Alaska could rewrite Arctic history

Parts of Alaska's mountainous Brooks Range were likely transported there from Greenland and a stretch of the Canadian Arctic much farther to the east, according to a series of studies detailing more than 300 million years of Arctic geologic history. The findings update our knowledge of the geologic evolution of the Arctic Ocean and could help revise predictions about the Arctic's oil, gas and mineral wealth. By explaining the formation of the Arctic Ocean in the Western Hemisphere -- known as the Amerasian Basin -- the research, which was funded by NSF's Division of Earth Sciences, provides new clues to the geologic history of the rapidly changing region.
