Next-gen icebreakers will call Seattle home

When the Coast Guard starts rolling out a new generation of heavy icebreakers on the Gulf Coast, the ships will be heading for a familiar port in the Pacific Northwest.

“I am pleased to announce that Seattle, Washington, will be the home of the Coast Guard’s new Polar Security Cutters,” Adm. Karl Schultz, commandant of the Coast Guard, said June 17 in a statement. “The Pacific Northwest has been the home of our icebreaking fleet since 1976, and I am confident that the Seattle area will continue to provide the support we need to carry out our critical operations in the polar regions.”

Heavy icebreakers come into play for guaranteeing access to Antarctica for supply deliveries, and supporting U.S. maritime security interests at high latitudes in the north as well as the south. But the current state of America’s fleet of heavy icebreakers is a source of concern.

That fleet has dwindled to one aging ship, the 43-year-old Polar Star, which has suffered through a string of breakdowns in recent years. During last year’s deployment to Antarctica, the ship experienced two flooding incidents and the loss of a gas turbine. This March, a team of Coast Guard and Navy divers had to patch a breach in the hull.

Meanwhile, the Polar Star’s sister ship, the Polar Sea, is out of commission and kept around only for spare parts. And the Coast Guard’s medium icebreaker, the Healy, isn’t capable of taking on Antarctic missions.

Fortunately, help is on the way.

Robots are readied to study Antarctic ice shelves

Researchers from the University of Washington and Columbia University are getting ready for an unprecedented months-long campaign to study Antarctica’s ice shelves from the ocean below, with backing from billionaire philanthropist Paul Allen.

The results are expected to lead to a better understanding of how ice retreats, and how climate change could affect the loss of polar ice sheets and the resulting rise in sea levels.

It’s a high-risk mission — but in this case, robots, not humans, are taking the risk.

“All of these instruments could be lost underneath the ice shelf,” said Spencer Reeder, director of climate and energy for Paul G. Allen Philanthropies.

Reeder said that’s a big reason why Allen, one of Microsoft’s co-founders, is funding the expedition to the tune of just under $2 million. The risks are too high for the traditional funders of polar research, but Allen’s backing could help UW’s Applied Physics Laboratory prove that its devices can do the job.

Senators want to close the icebreaker gap

Two U.S. senators from opposite sides of the aisle – Washington Democrat Maria Cantwell and Alaska Republican Lisa Murkowski – teamed up on Friday to hold President Barack Obama to his word when it comes to beefing up the U.S. Coast Guard’s sagging fleet of polar icebreakers.

“We are falling behind in our icebreaking capacity,” Cantwell said during a news conference at Seattle’s Vigor Shipyards, where the medium icebreaker Healy is undergoing maintenance. She underscored her concern in a letter that was sent to Obama and released to journalists.

“There is a race to the Arctic – and the United States isn’t even in the game,” Cantwell said in the letter.
