Figure 1. This BLM map depicts the principal meridians and baselines used for surveying states (colored) in the PLSS.. The following are the principal and guide meridians and base lines of the United States, with the year established and a brief summary of what areas' land surveys are based on each.
Siple Station (/ ˈ s aɪ p ə l / SIGH-p'l) [3] was a research station in Antarctica), established in 1973 by Stanford's STAR Lab, to perform experiments that actively probed the magnetosphere using very low frequency (VLF) waves. [2]
Kunlun Station (simplified Chinese: 昆仑站; traditional Chinese: 崑崙站; pinyin: Kūnlún Zhàn) is the southernmost of five Chinese research stations in Antarctica. When it is occupied during the summer, it is the second-southernmost research base in Antarctica , behind only the American Amundsen–Scott South Pole Station at the ...
The 2017 novel South Pole Station by Ashley Shelby is set at the Amundsen-Scott South Pole station of 2002-2003, prior to the opening of the new facility. The 2019 film Where'd You Go, Bernadette features the station prominently and includes scenes of its construction at the closing credits, although the actual station depicted in the film is ...
The pole of the lower hemisphere is called the nadir. [5] The following are two independent horizontal angular coordinates: Altitude (alt.), sometimes referred to as elevation (el.) or apparent height, is the angle between the object and the observer's local horizon. For visible objects, it is an angle between 0° and 90°. [b]
Meridians run between the North and South poles. In geography and geodesy, a meridian is the locus connecting points of equal longitude, which is the angle (in degrees or other units) east or west of a given prime meridian (currently, the IERS Reference Meridian). [1] In other words, it is a coordinate line for longitudes, a line of longitude.
For example, on a GEOREF chart, Naval Air Station Patuxent River (38°17′10″N 76°24′42″W) / (38.286108, -76.4291704) is located (to the nearest minute) at position GJPJ3417. To locate the position from the coordinates, proceed as follows: Right from 180° longitude to longitude zone G; Up from the South Pole to latitude zone J
It is here that the southernmost human habitation on Earth is located: Amundsen–Scott South Pole Station (U.S. Administered Base). Vostok Station is the most isolated research base on the continent (located at ), and it is situated over the southernmost lake in the world, Lake Vostok, a subglacial lake 4,000 metres (13,000 feet) under the ...
