First Ship to Cross the Antarctic Circle

First Ship to Cross the Antarctic Circle

On January 17, 1773, British explorer Captain James Cook became the first to sail past the Antarctic Circle. This event took place during Cook's second voyage into the Pacific, which lasted from 1772 to 1775. His mission was to determine whether there were any large and habitable land masses at the extreme southern latitudes of Earth, to be accomplished by circumnavigating the world as far south as possible. Cook set out with two ships, the Resolution and the Adventure, which departed from England and, after sailing around the Cape of Good Hope, went southward toward the Antarctic. Although Cook crossed the Antarctic Circle in January of 1773, he never sighted Antarctica itself. The first confirmed sightings of that continent would not take place until the 1820s.

Cook was forced, by the weather and his need for supplies, to sail south in the summer months (January is a summer month in the Southern Hemisphere) and then back to familiar ports of call, such as Tahiti, in the winter months. Although Cook failed to find a habitable continent as had been hoped, he did discover two small island chains, namely the South Georgia Islands and the South Sandwich Islands. His voyage also provided invaluable navigational and scientific data. For his achievements, Cook was made a member of the Royal Society after he returned to Britain in 1775.
