Jim gears up to dive the wreck of the Arctic exploration ship Fox in Querquertersuaq, Greenland, while filming an episode of The Sea Hunters. Jim, with Mike and Warren Fletcher, explored the ice-flattened remains of the tiny steamer, famous for its role in determining the fate of ill-fated Franklin expedition. Owned by Lady Jane Franklin, Fox, under the command of Francis Leopold McClintock surveyed the Canadian Arctic archipelago in 1857-1859 and returned with traces of the lost expedition, including the only written note from the lost explorers, which told of Franklin's death and the abandonment of his ships by the survivors.
