Coast Guard Cutter Polar Sea departs for Bering Sea cruise
"Changing ice conditions are likely to influence the potential expansion of Bering Sea fisheries further north as well as to shrink arctic habitat currently available on the shallow continental shelf," said Cooper.
Data and samples to be collected include sea floor sediments, sea ice and water samples, and plankton. Other topics of research include studies of the distributions of birds and marine mammals, including the world population of Spectacled Eiders that winters south of Saint Lawrence Island.
"The overall effort will contribute to understanding how climate change and reduced ice cover will impact the Bering Sea ecosystem," said Cooper.
The Polar Sea was built by Lockheed Shipbuilding and Construction Company in Seattle. Commissioned in 1978, the Polar Sea has operated around the globe and is designed to perform science, icebreaking, and all Coast Guard missions in both Polar Regions. With a reinforced hull and up to 75,000 horsepower, the cutter can break up to 21 feet of ice, or 6 feet of ice at a continuous speed of 3 knots. The ship’s icebreaking capabilities allow the crew to perform logistics, search and rescue, ship escort, environmental protection, and enforcement of laws and treaties in places most ships cannot reach.
