1911 Encyclopædia Britannica/Antarctic

ANTARCTIC (Gr. ἀντί, opposite, and ἄρκτος, the Bear, the northern constellation of Ursa Major), the epithet applied to the region (including both the ocean and the lands) round the South Pole. The Antarctic circle is drawn at 66° 30′ S., but polar conditions of climate, &c., extend considerably north of the area thus enclosed. (See Polar Regions.)
