picture info	Prime Meridian A prime meridian is an arbitrary meridian (a line of longitude) in a geographic coordinate system at which longitude is defined to be 0°. Together, a prime meridian and its anti-meridian (the 180th meridian in a 360°-system) form a great circle. This great circle divides a spheroid, like the Earth, into two hemispheres: the Eastern Hemisphere and the Western Hemisphere (for an east-west notational system). For Earth's prime meridian, various conventions have been used or advocated in different regions throughout history. The Earth's current international standard prime meridian is the IERS Reference Meridian. It is derived, but differs slightly, from the Greenwich Meridian, the previous standard. A prime meridian for a planetary body not tidally locked (or at least not in synchronous rotation) is entirely arbitrary, unlike an equator, which is determined by the axis of rotation. However, for celestial objects that are tidally locked (more specifically, synchronous), th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
picture info	Banks Island Banks Island is one of the larger members of the Arctic Archipelago. Situated in the Inuvik Region, and part of the Inuvialuit Settlement Region, of the Northwest Territories, it is separated from Victoria Island to its east by the Prince of Wales Strait and from the mainland by Amundsen Gulf to its south. The Beaufort Sea lies to its west, and to its northeast M'Clure Strait separates the island from Prince Patrick Island and Melville Island. It is home to at least fourteen mammal species including the Peary caribou, barren-ground caribou, and polar bears. At one time over 68,000 muskoxen lived on the island, the majority of the world's population. However, the bacterium ''Erysipelothrix rhusiopathiae'' has led to a sharp decline in their numbers. The island is the summer home to hundreds of thousands of migratory birds who nest at Banks Island Migratory Bird Sanctuary No. 1 and Banks Island Migratory Bird Sanctuary No. 2. As of the 2016 census it had a human population ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
