From 22 July to 5 August 1946, all activities in Operation Nanook centered around Thule; Norton Sound remained at anchor there, in North Star Bay, servicing her two PBM's. Meanwhile, Whitewood and Atule operated from North Star Bay as they conducted exercises and tests in the Smith Sound-Kane Basin area. On 5 August 1946, Norton Sound and Whitewood headed for Dundas Harbour, Nunavut and Devon Island, in order to attempt air and surface operations there. Unfortunately, the ships found the harbor iced over, with a belt of pack ice extending out three miles down the coast. The Northwind broke ice in support of Operation Nanook.
