"Staten Island" returned from her Antarctic voyage on 6 April 1967 and was then sent into the Arctic Ocean above Alaska for four months during the spring and summer of 1967 during which time she ran aground while traveling west from Prudhoe Bay and sustained minor damage. "Staten Island" then broke ice to assist her sister ship, , twice during the 1967 fall ice season; in September 1967 "Northwind" lost a propeller and became locked in the ice, and she was trapped again in October–November 1967 north-northwest of Point Barrow, Alaska.
