British, Australian and New Zealand Antarctic Research Expedition
In 1929 – 1931 further extensive claims to sovereignty were made by the British, Australian and New Zealand Research Expedition (BANZARE) again led by Douglas Mawson.
In two summer voyages Discovery and the expedition aircraft traversed the whole coastline from 45°E to 160°E and in the process defined the limits of what was to become Australian Antarctic Territory (AAT).
The voyages were mainly ship-based, with little exploration on land. The scientific plans driving Mawson's expeditions were wide-ranging and often quite specialised. They included studies of the weather, the oceans, geology, physics, biology, glaciology and bacteriology.
Mawson and the other early Antarctic expeditioners started a series of weather reports which are being continued today as part of scientific work on predicting weather patterns and understanding climate change. Another important task was mapping, as Antarctica was an almost unknown land. Maps were drawn on ship and on land by Hodgeman, the cartographer (map maker) and sketch artist at the Australasian Antarctic Expedition Main Base.
However, the main occupation of the BANZARE expedition was marine science, which included extensive oceanographic work and marine biological sampling. Examination of the various species collected was done over the next fifty years by specialists all over the world, and their results described in the thirteen volumes of the BANZARE Scientific Reports.
