104th Meridian West
The meridian 104° west of Greenwich is a line of longitude that extends from the North Pole across the Arctic Ocean, North America, the Pacific Ocean, the Southern Ocean, and Antarctica to the South Pole. The 104th meridian west forms a great circle with the 76th meridian east. In the United States, the western boundaries of North Dakota, South Dakota, and Nebraska and the eastern boundaries of Montana and Wyoming lie on the meridian 27° west of Washington, which is a couple of miles west of the meridian 104° west of Greenwich. In Colorado, the meridian 104° west of Greenwich roughly defines the eastern extent of the region of high plains protected by the Southern Rocky Mountains. From Pole to Pole Starting at the North Pole and heading south to the South Pole The South Pole, also known as the Geographic South Pole, Terrestrial South Pole or 90th Parallel South, is one of the two points where Earth's axis of rotation intersects its surface.

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] |
Washington Meridian
The Washington meridians are four meridians that were used as prime meridians in the United States and pass through Washington, D.C. The four which have been specified are: # through the Capitol # through the White House # through the old Naval Observatory # through the new Naval Observatory. Their longitudes may be reported in three ways: # relative to the local vertical used by astronomic observations # relative to NAD 27 ( North American Datum 1927), an ellipsoid of revolution that is at mean sea level beneath triangulation station Meades Ranch, Kansas (not Earth-centered); # relative to NAD 83, an Earth-centered ellipsoid of revolution with dimensions chosen to best fit the undulating (±100 m) geoid (world-wide mean sea level). NAD83 longitude of the Capitol is about 1.1 arc seconds less than its NAD27 longitude; astronomic longitude there is about 4 arc seconds less than NAD83. Capitol meridian Pierre (Peter) Charles L'Enfant specified the first meridian in his 1791 "' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Commercial oil production Cameron Island is notable as being the only site which has been developed for commercial oil production in the Canadian Arctic islands. From 1985 to 1996 the double-hulled tanker M.V.Arctic shipped the light crude from Bent Horn in the south-west of the island to Montreal. A total of was produced until the field was abandoned in 1996. The initial discovery, in 1974 by Panarctic Oils Ltd, reflected the urgency to find new sources of crude oil after the 1973 oil crisis. The abandonment in 1996 reflects the difficulties of exploiting the resource in this harsh environment, although the current production licence (held by Canada Southern Petroleum Ltd) expired in 2010 ...
