The expedition observed more than 1.5 million square miles of Antarctica, half of it previously unexplored, and took 15,000 aerial photographs.
The following season the U.S. Navy Second Antarctic Developments Project (Operation Windmill) used ship-based helicopters to get geodetic ground control for the aerial photographs. The expedition contributed to production of the first medium-scale maps of the region and influenced decisions regarding locations of stations for the International Geophysical Year (IGY) that occurred 12 years later.
At a time when other nations had embarked on programs of permanent bases, the U.S. Navy Second Antarctic Developments Project also was a vehicle for continuing the U.S. presence in Antarctica.

Sir Douglas Mawson (1882-1958) is Australia's most renowned Antarctic scientist and explorer.
In 1911 Mawson organized and commanded the Australasian Antarctic Expedition (AAE 1911-14) and was the sole survivor of a three-man sledging journey that ended tragically. Mawson was knighted in recognition of his leadership of this expedition.
