45th parallel south

45° 45th parallel south The 45th parallel south is a circle of latitude that is 45 degrees south of the Earth's equatorial plane. Highway sign marking the 45th parallel in New Zealand. It is the line that marks the theoretical halfway point between the equator and the South Pole. (The true halfway point is somewhat south of this parallel because the Earth is not a perfect sphere but bulges at the equator and is flattened at the poles.[1]) Unlike its northern counterpart it passes mostly over open ocean. It crosses the Atlantic Ocean, the Indian Ocean, Australasia, the Pacific Ocean and South America. Starting at the Prime Meridian and heading eastwards, the parallel 45° south passes through: Co-ordinates Country, territory or sea Notes 45°0′S 0°0′E / 45°S 0°E / -45; 0 (Prime Meridian) Atlantic Ocean 45°0′S 20°0′E / 45°S 20°E / -45; 20 (Indian Ocean) Indian Ocean 45°0′S 147°0′E / 45°S 147°E / -45; 147 (Pacific Ocean) Pacific Ocean Tasman Sea 45°0′S 167°8′E / 45°S 167.133°E / -45; 167.133 (New Zealand)  New Zealand South Island 45°0′S 171°6′E / 45°S 171.1°E / -45; 171.1 (Pacific Ocean) Pacific Ocean Passing just south of Guamblín Island,  Chile 45°0′S 74°23′W / 45°S 74.383°W / -45; -74.383 (Chile)  Chile Islands in the Chonos Archipelago including James Island and Melchor Island, and the mainland 45°0′S 71°33′W / 45°S 71.55°W / -45; -71.55 (Argentina)  Argentina 45°0′S 65°35′W / 45°S 65.583°W / -45; -65.583 (Atlantic Ocean) Atlantic Ocean Map of all coordinates from Google Map of all coordinates from Bing Export all coordinates as KML Export all coordinates as GeoRSS Map of all microformatted coordinates Place data as RDF See also 44th parallel south 46th parallel south v · d · eCircles of latitude / Meridians Equator Tropic of Cancer Tropic of Capricorn Arctic Circle Antarctic Circle Equator Tropic of Cancer Tropic of Capricorn Arctic Circle Antarctic Circle Equator Tropic of Cancer Tropic of Capricorn Arctic Circle Antarctic Circle W 0° E 30° 60° 90° 120° 150° 180° 30° 60° 90° 120° 150° 180° 5° 15° 25° 35° 45° 55° 65° 75° 85° 95° 105° 115° 125° 135° 145° 155° 165° 175° 5° 15° 25° 35° 45° 55° 65° 75° 85° 95° 105° 115° 125° 135° 145° 155° 165° 175° 10° 20° 40° 50° 70° 80° 100° 110° 130° 140° 160° 170° 10° 20° 40° 50° 70° 80° 100° 110° 130° 140° 160° 170° 0° 10° 20° 30° 40° 50° 60° 70° 80° 90° 10° 20° 30° 40° 50° 60° 70° 80° 90° 5° N 15° 25° 35° 45° 55° 65° 75° 85° 5° S 15° 25° 35° 45° 55° 65° 75° 85° 45x90 45x90 45x90 45x90
