In April, PMEL and JISAO scientists and engineers teamed up with Saildrone, Inc. to test two Saildrones in the harsh environment of the Bering Sea for the first time. The unmanned instruments sailed from Dutch Harbor, AK on April 22. They have traveled over 2,000 miles each since then, taking over 40 million measurements as they sail north following the ice retreat. With the Arctic environment changing rapidly, the success of these vehicles couldn’t come at a better time. The measurements taken across the eastern Bering Sea have the potential to provide a comprehensive picture of the changes that occur in the late spring environment when the ice is retreating.
