Roald Amundsen (1872-1928) was Norwegian explorer, first man to reach the South Pole (1911).
Roald Amundsen first navigated completely Amundsen Gulf, an inlet, opening of the Arctic Ocean in Northwest Territories, Canada, on the Beaufort Sea, during his expedition of 1903 to 1906 to the region.
A Norwegian expedition explored and named Amundsen Sea, an arm of the southern Pacific Ocean off the coast of Marie Byrd Land, Antarctica, in the late 1920s.
At the turn of the late 19th century, Amundsen led the expedition successfully to traverse the Northwest Passage.
