* Polar coordinate system, a 2D or 3D coordinate system, determined by an angle and a distance

* Polar coordinate system represents a point in the plane by a distance from the origin and an angle measured from a reference line intersecting the origin.

Polar distance may refer to:

* Polar distance ( geometry ), more correctly called radial distance, typically denoted r, a coordinate in polar coordinate systems ( r, θ )

* Polar distance ( botany ) is used in the classification of pollens

Within the last several years, Nike, Polar and other companies have produced and marketed sports watches for runners that include footpods, containing accelerometers to help determine the speed and distance for the runner wearing the unit.

Polar region receive less intensive solar radiation because the sun's energy arrives at an oblique angle, spreading over a larger area, and also travels a longer distance through the Earth's atmosphere in which it may be absorbed, scattered or reflected, which is the same thing that causes winters to be colder than the rest of the year in temperate areas.

Polar distance ( PD ) is an astronomical term associated with the celestial equatorial coordinate system Σ ( α, δ ) and it is an angular distance of a celestial object on its meridian measured from the celestial pole, similar as declination ( dec, δ ) is measured from the celestial equator:

Polar distance is not affected by the precession of the equinoxes.

* Polar jet, a phenomenon in astronomy, where streams of matter are emitted along the axis of rotation of a compact object

There are six categories within the SSC scheme: Dry Polar ( similar to continental polar ), Dry Moderate ( similar to maritime superior ), Dry Tropical ( similar to continental tropical ), Moist Polar ( similar to maritime polar ), Moist Moderate ( a hybrid between maritime polar and maritime tropical ), and Moist Tropical ( similar to maritime tropical, maritime monsoon, or maritime equatorial ).

The Nordisk company was set up there in 1906 by Ole Olsen, a fairground showman, and after a brief period imitating the successes of French and British film-makers, in 1907 he produced 67 films, most directed by Viggo Larsen, with sensational subjects like Den hvide Slavinde ( The White Slave ), Isbjørnenjagt ( Polar Bear Hunt ) and Løvejagten ( The Lion Hunt ).

After returning home he went on a lecture circuit and wrote The People of the Polar North ( 1908 ), a combination travel journal and scholarly account of Inuit folklore.

However, the party made good progress despite poor weather, and had completed the Polar Plateau stage of their journey, approximately 300 miles ( 500 km ), by 7 February.

By topography and other natural features, Ural is divided, from north to south, into the Polar ( or Arctic ), Nether-Polar ( or Sub-Arctic ), Northern, Central and Southern parts.

En route the South Pole party discovered the Beardmore Glacier, ( named after Shackleton's patron ), and became the first persons to see and travel on the South Polar Plateau.

* Polar curve ( a point and a curve ), a generalization of a point and a line

* Polar ( satellite ), a satellite launched by NASA in 1996

* Polar ( cataclysmic variable ), a strongly magnetic cataclysmic variable star system

* Polar curve ( aviation ), a diagram that depicts the gliding performance of an aircraft

* Polar ( album ), second album by the High Water Marks

Porter was a in charge of astronomical observations on the Ziegler Polar Expeditions financed by New York businessman William Ziegler in 1901 and 1903.

Polar mounts work in a similar way to astronomical equatorial mounts in that they point at objects at fixed hour angles that follow the astronomical right ascension axis.

Montgomery also predicted in the 1970s and 1980s, that America would have a " walk-in " as president in the 1990s, (" unsure which term, 1992 or 1996 ") before the Polar Shift, which was to happen " in the last months of the century " as it seemed to " the Guides.

In a meta analysis of the published work in aquatic ecosystems since the term biodiversity appeared in the bibliography, the Arctic and Antarctic Polar regions were found to still be unexplored.

Much of the biology in the area occurs along the major fronts of the current, the Subtropical, SubAntarctic, and the Antarctic Polar fronts, these are areas associated with well defined temperature changes.

Although he did not live to see it occur, he is associated with the organisation of the first International Polar Year.

Moreover, the sub-population of Ursus maritimus polar bears found here is a genetically distinct set of Polar Bears associated with the Barents Sea region.

Polar bears are found in this locale ; in fact, the sub-population found here is a genetically distinct taxon associated with the Barents Sea region.

A significant number of Polar bears are found at Hopen in the winter ; moreover, the sub-population of Ursus maritimus found here is a genetically distinct taxon of Polar Bears associated with the Barents Sea region.

His early work in particular owes an acknowledged stylistic debt to Photek, and he was initially mostly associated with the Certificate 18 record label, alongside Photek, Klute and fellow Norwegian Polar.

Surveys of the SW Indian Ocean have shown phytoplankton group variation based on their location relative to the Polar Front, with diatoms dominating South of the front, and dinoflagellates and flagellates in higher populations North of the front < sup >.</ sup >

Polar unit vectors at two times t and t + dt for a particle with trajectory r ( t ); on the left the unit vectors u < sub > ρ </ sub > and u < sub > θ </ sub > at the two times are moved so their tails all meet, and are shown to trace an arc of a unit radius circle.

* 1999 – NASA loses radio contact with the Mars Polar Lander moments before the spacecraft enters the Martian atmosphere.

Polar bears appear on Jan Mayen, although in diminished numbers compared with earlier times.

Distribution area from Polar overlaps with Coca-Cola of Northern New England in Massachusetts ; for example, Shaw's Supermarkets and Stop & Shop are generally supplied by Polar while Market Basket uses CCNNE.

Polar bears can breed with brown bears to produce fertile grizzly – polar bear hybrids, rather than indicating that they have only recently diverged, the new evidence suggests more frequent mating has continued over a longer period of time, and thus the two bears remain genetically similar.

Other public offices with presence on Svalbard are the Norwegian Directorate of Mining, the Norwegian Polar Institute, the Norwegian Tax Administration and the Church of Norway.

After the war, in 1947 – 1948, Chum – Labytnangi railway, built with the forced labor of Gulag inmates, crossed the Polar Urals.

The mountains of the Polar Ural have exposed rock with sharp ridges though flattened or rounded tops are also found.

The Nether-Polar Ural is wider, up to and higher than the Polar Ural, with the highest peaks of the Mount Narodnaya, the Mount Karpinsky ( Urals )) and the Manaraga ).

Both Polar and Nether-Polar Urals are typically Alpine ; they bear traces of Pleistocene glaciation, along with permafrost and extensive modern glaciation, that includes 143 extant glaciers.

Based on studies by glaciologist Lonnie Thompson, professor at Ohio State University and researcher with the Byrd Polar Research Center, a number of indicators shows there was a global change in climate 5, 200 years ago, probably due to a drop in solar energy output as hypothesized by Ohio State University.

Drygalski led the first German South Polar expedition with the ship Gauss to explore the unknown area of Antarctica lying south of the Kerguelen Islands.

Polar solvents are those with a molecular structure that contains dipoles.

In 2012, Simon was awarded the Polar Music Prize ( shared with Yo-Yo Ma ).

In July 2011 The Federal Aviation Administration ( FAA ) issued a ruling that approves the use of Iridium for Future Air Navigation System ( FANS ) data links, enabling satellite data links with air traffic control ( ATC ) for aircraft flying in the FANS environment including areas not served by Inmarsat ( above or below 70 Degrees Latitude ) which includes Polar routes.

Brest is also an important research centre, mainly focused on the sea, with among others the largest Ifremer ( French Research Institute for Exploitation of the Sea ) centre, le Cedre ( Centre of Documentation, Research and Experimentation on Accidental Water Pollution ) and the French Polar Institute.
