U.S. Coast Guard Petty Officer 2nd Class Dan Morales uses a water ram to clear a clogged shaft seal drain pipe Jan. 10, 2020, aboard the U.S Coast Guard Cutter Polar Star about 18 miles north of McMurdo Station, Antarctica. The shaft was a source of a leak during Operation Deep Freeze 2018-2019, which required the use of Coast Guard divers to effect the repair from underneath the 399-foot icebreaker. The crew of Polar Star is participating in Operation Deep Freeze 2019-2020 in order to break the ice near McMurdo Station in order escort refuel and resupply ship.
