the point at which the imaginary axis of the earth’s rotation intersects its surface in the southern hemisphere. All other points on the earth’s surface are north of the south pole. The south pole is situated on the continent of Antarctica, close to the Pacific coast at an elevation of 2,800 m. The ice in the vicinity of the south pole reaches a thickness of 2,810 m. The average annual air temperature for the period 1957–61 was –48.6°C, with a maximum of −14.7°C and a minimum of –78.9°C. The polar day lasts about 179 days, from September 23 to March 20–21 (not considering refraction). (See alsoPOLES, GEOGRAPHIC.)
