The Arctic Circle is the name of the parallel of latitude located at 66°32′ or 66.5º north of the Equator, which is the equivalent of 23.5º from the North Pole. Because this distance matches the inclination of the Earth’s axis, the Arctic Circle receives 24 hours of sunlight on the summer solstice, and north of the Arctic circle for longer than that, with the North Pole having continuous sun for six months. This is why the region is called "The Land of the Midnight Sun."
Explorers of the Arctic Circle Region
Explorers searched the Arctic Circle region seeking a Northwest Passage or Northeast Passage, studying development possibilities, and searching for resources. It has also been the site for scientific study related to a number of subjects, including depletion of the ozone layer. Noted explorers of the region in clued William Baffin, Vitus Bering, Martin Frobisher, and Henry Hudson, all of whose names are immortalized in eponymous natural features. Other noted explorer include Roald Amundsen, who went through both the Northwest and Northeast Passages, and Robert E. Peary, whose claim to have been first to the North Pole in 1909 is disputed.
