MCMURDO, ANTARCTICA- The Coast Guard Cutter Polar Sea moors outboard of the US Naval Ship Paul Buck as the Buck offloads fuel stores for the station.  As part of Operation Deep Freeze, a tanker and a container ship come down to the McMurdo annually to offload supplies and onload waste.  The Polar Sea has been in the area since the beginning of January to break the ice and clear a navigable channel for these ships.
