For the past five years, the National Science Foundation (NSF) has supported an international and interagency team of researchers, led by investigators at the University of Washington, who are studying the physical properties of the Arctic Ocean and the potential effects of changes in the Arctic on global climate. Among the various tools they use are a suite of instruments attached to a mooring cable. The cable is as long as Mt. Rainier is tall. The mooring, deployed from a temporary camp at the Pole, keeps the instruments in place and collecting temperature, ice-thickness and other data for a full year.
