A glimpse from within the cavern of the Mertz Glacier, Australasian Antarctic Expedition, 1911–1914

The Australasian Antarctic Expedition was the first major scientific expedition by Australians beyond their shores. It explored some 6347 kilometres of mainland Antarctica as well as Macquarie Island. The analysis and report of the scientific data collected during the expedition was so extensive that it filled 22 volumes when it was published in 1947.
