The Karluk, the flagship of the Canadian Arctic Expedition, sank after being crushed by ice.

Karluk was an American-built brigantine which, after many years' service as a whaler, was acquired by the Canadian government in 1913 to act as flagship to the Canadian Arctic Expedition. While on her way to the expedition's rendezvous at Herschel Island, Karluk became trapped in the Arctic pack ice and, after drifting for several months, was crushed and sank in January 1914. Of the 25 aboard, eleven died, either during the attempts to reach land by marching over the ice, or after arrival at the temporary refuge of Wrangel Island.

The Canadian Arctic Expedition 1913–1918 was a scientific expedition in the Arctic Circle organized and led by Vilhjalmur Stefansson. The expedition was originally to be sponsored by the (US) National Geographic Society and the American Museum of Natural History. Canada took over the sponsorship because of the potential for discovery of new land and Stefansson, who though born in Canada was now an American, re-established his Canadian citizenship. The expedition was divided into a Northern Party led by Stefansson, and a Southern Party led by R M. Anderson.

The last voyage of the Karluk, flagship of the Canadian Arctic Expedition of 1913–16, ended with the loss of the ship in the Arctic seas, and the subsequent deaths of nearly half her complement of 25.
