Long Term Bottom Anchored Mooring
Beginning in April 2001, scientists from the University of Washington have installed a 4300-meter (2.6 mile) long mooring from a remote camp located near the North Pole Environmental Observatory. Instruments mounted on this installation measure various properties of the ocean, including temperature, salt content, currents, and even biological and chemical properties of the seawater. Every year, engineers must recover (pick up) this mooring, download a year’s worth of data, and redeploy it (put it back in the ocean). The recovery and redeployment procedure is an epic that can take a week or more. This mooring tells scientists how the water at the North Pole changes from day to day and year to year.
