Although the structure rises well above the seabed, it tops out at about 1,600 meters below the water’s surface, so it is too deep to pose any risks to navigation.
New data is used to map a volcano-like feature discovered this fall by science teams aboard the U.S. Coast Guard Cutter Healy, a polar-class icebreaker used for Arctic research. The scientists found the structure on the continental slope off northern Alaska.
The discovery came as scientists from different organizations were aboard the Healy, one of two polar-class Coast Guard icebreaking cutters, were working on a mission to better understand uncharted waters in the Chukchi and Beaufort seas north of Alaska. Researchers from the National Oceanic and Atmospheric Administration Ship Fairweather and the University of New Hampshire analyze mapping data in the U.S. Coast Guard Cutter Healy’s computer lab while the cutter transits the Beaufort Sea on Oct. 16.
Capt. Meghan McGovern, the commanding officer of the NOAA Ship Fairweather, is part of the Healy mapping team and commented on the discovery.
