The Development of Exploration and Scientific Research in Antarctica

Academic Reading Passage

The modern scientific age in Antarctica really began with the introduction of aircraft in the 1920s. Aircraft transformed the possibilities of exploring the frozen continent around the South Pole, because before that Antarctic travel had been limited to the use of dog teams pulling sledges. A plane could survey thousands of square kilometres an hour, equivalent to a whole summer's work using previous techniques. However, the first planes in Antarctica, such as the Lockheed Vega and the Ford Trimotor, were unreliable in freezing conditions. This made polar flying particularly hazardous, since there was little chance of rescue if a plane was forced down in a remote region.

It was in 1928 that Herbert Wilkins hoped to make the first flight in Antarctica, attempting to cross the continent. A further attempt in 1930 was also unsuccessful, but Wilkins' aerial photographs seemed to show that the Antarctic Peninsula was in fact an island, not part of the continent as had previously been thought. This new theory caused some excitement among geographers and cartographers. However, the British Grahamland Expedition of 1934–37 proved conclusively that the Antarctic Peninsula was attached to the rest of the continent.

In 1929, the American pilot Richard Byrd flew over the South Pole, and another American, Lincoln Ellsworth, made a successful Antarctic flight in 1935. Although Ellsworth claimed a sector of the continent for the USA, the American government did not follow it up. In 1938, the German explorer Alfred Ritscher led an expedition south. Once Antarctica was reached, the aircraft stored in pieces on the ship's deck was reconstructed, launched and used to stake a claim by dropping thousands of tiny flags from the air.

A significant motivation behind many Antarctic expeditions right up to the 1940s was the spirit of adventure. Many had substantial private funding, while the vast majority of expeditions since 1940 have been funded by governments, usually for political reasons and scientific research.

The setting up of the Research and Development Committee in Britain was a significant development in Antarctic science. Its 1920 report proposed detailed scientific investigations of whales. Scientists occupied a shore station at Grytviken and three research ships were commissioned. The Discovery Investigations were completely funded by a tax on whaling businesses operating in the area.

The idea of international scientific collaboration at the poles was proposed in 1875. The first Polar Year took place in 1882–83 and a second 50 years later. Both were timed to coincide with a period when the sun was at its lowest activity. A third Polar Year followed, and in 1951 the programme was expanded globally and renamed the International Geophysical Year (IGY). Antarctica received special attention because of its influence on global weather.

The IGY took place in 1957–58. Dr Vivian Fuchs' privately funded Trans Antarctic Expedition crossed the continent coast to coast in 99 days using modified tractors. Its measurements produced the first estimates of the volume of ice across the continent. The success of the IGY led to its extension and directly to a treaty regulating future human conduct in Antarctica.
