MCMURDO SOUND, Antarctica (Jan. 2) -- During Operation Deep Freeze 2002, both the 399-ft. Polar Star (WAGB-10) and Polar Sea (WAGB-11) jointly broke an ice path to create an access channel for supply ships in McMurdo Sound. Supply ships must offload their cargo during the summer months of January and February to ensure that the extensive program of research activities can be conducted and that the facilities in the area remain operational year-round.
