The Antarctic continent evokes images of extreme environments, rugged explorers, unusual animal life, and, especially for scientists, discovery. Science has, in fact, been the driving force for much of the effort to explore this harshest of continents. Perhaps it was the efforts of Robert Scott and members of his expedition, who studied the wintering habits of the Emperor Penguin, recounted... 

Penguins occasionally dive deeply in their quest for food, which consists primarily of fish and crustaceans. For example. Emperor penguins reportedly can dive 850 ft (260 m) below the surface and remain there for about 18 minutes. 

It forced the administration to concede that ten species of penguins, including the emperor penguin, were endangered, then sued again when the government missed its deadline for protecting those species.

On January 24, 1841, these explorers also discovered an island at 78°S and 168°E located off the coast of Victoria Land. The latitude of this island exceeded the most southern position reached by James Weddell, which Ross and Crozier celebrated by issuing double rations of rum to their crews. Ross named the two volcanoes on the island after his ships Erebus and Terror and the island itself is known to us as Ross Island. Captain Crozier s name identifies a prominent peninsula on Ross Island where the famous rookery of Emperor Penguins is located. 

Another legendary sledging trip was undertaken on June 27 of 1911 by Edward Wilson, Apsley Cherry-Garrard, and Henry (Birdie) Bowers who man-hauled sleds from Cape Evans to Cape Crozier in order to recover some embryos of Emperor penguin chicks before they hatched. This trip took place in the dark in extremely cold and windy weather. The team did reach Cape Crozier, where they collected three embryos, and returned to Cape Evans on August 2 after a trip that also lasted 36 days.
