One of the traditions of US icebreakers operating in the Arctic is “ice liberty.” When an icebreaker encounters a thick ice floe, the crew is allowed liberty to get off the vessel to walk about or play games from touch football to hockey.
This year as the icebreaker USCGC Healy transited the Northwest Passage for the first time since 2005, ice liberty was canceled. In the melting Arctic, no ice floe was thick enough to be suitable.
“A lot of the floes had melt ponds with holes in them like Swiss cheese,” said Capt. Kenneth Boda, commander of the Seattle-based icebreaker told the Seattle Times. “We couldn’t get the right floe.”
