[[Ernest Shackleton]], who had been a member of Scott's expedition, organized and led the [[Nimrod Expedition]] from 1907 to 1909. The expedition's primary objective was of reaching the South Pole. Based in [[McMurdo Sound]], the expedition pioneered the [[Beardmore Glacier]] route to the [[South Pole]], and the (limited) use of motorised transport. Its southern march reached 88°23'S, a new Farthest South record 97 [[nautical miles|geographical miles]] from the Pole before having to turn back. During the expedition, Shackleton was the first to reach the polar plateau. Parties led by [[T. W. Edgeworth David]] also became the first to climb [[Mount Erebus]] and to reach the [[South Magnetic Pole]].
