'Erebus Eruption, June 14th 1908, 3.45 p.m. Showing upper air currents', (1909). Diagram showing the volcano Erebus erupting. Anglo-Irish explorer Ernest Shackleton (1874-1922) made three expeditions to the Antarctic. During the second expedition, 1907-1909, he and three companions established a new record, Farthest South latitude at 88°S, only 97 geographical miles (112 statute miles, or 180 km) from the South Pole, the largest advance to the pole in exploration history. Members of his team also climbed Mount Erebus, the most active volcano in the Antarctic. Shackleton was knighted by King Edward VII for these achievements. He died during his third and last 'oceanographic and sub-antarctic' expedition, aged 47. Illustration from The Heart of the Antarctic, Vol. I, by E. H. Shackleton, C.V.O.
