The crew of the U.S. Coast Guard Cutter Polar Star arrived at the National Science Foundation’s McMurdo Station Tuesday after cutting a resupply channel through more than 60 miles of Antarctic ice in the Ross Sea.

The path through the seasonal and multi-year ice helps the annual delivery of operating supplies and fuel for two of NSF’s three U.S. research stations in Antarctica.

The Polar Star is America’s only operational heavy icebreaker that is capable of conducting the Antarctic resupply mission. The cutter, which was built more than 40 years ago, has a crew of more than 140 people, is 399-feet long, weighs 13,500 tons and uses 75,000 horsepower to muscle its way through ice thicknesses of up to 21 feet.

The Coast Guard says that in previous years Polar Star typically worked through approximately 12 to 13 miles of ice to reach McMurdo Station. This year, however, there was more than 60 miles of ice to break with thickness ranging from two feet to more than 10 feet.

“We experienced a significantly larger ice field this year compared to the last several years,” said Capt. Michael Davanzo, commanding officer of the Polar Star. “In several areas, the ice was under considerable pressure and covered with several inches of snow, slowing our progress. Despite these challenges, the crew worked around the clock to prepare the resupply channel before the arrival of the first ship.”

After refueling at McMurdo Station, the Polar Star crew will continue to develop and maintain the ice channel in preparation of the first of two resupply ships, which are scheduled to arrive in the area in late January.

The Coast Guard Cutter Polar Star is homeported in Seattle.
