OK, three examples of Arctic crashes, earliest dating to 1946. Reading the accounts, all developed problems while attempting to land at established runways, a fairly common type of accident, and not at all like the Captain Sully event cited by the OP.

Apparently there haven't been any Arctic "Sullenbergers.' Planes developing problems at altitude may not have the chance to glide to an impromptu landing. We experienced the fatal plunge of an Alaska Airlines plane off Anacapa Island about ten years ago which plummeted into the water from about 17,000 feet. Evidently the pilot was attempting to reach an airfield when he lost control. Survival was not an issue.
