While the South Pole lies on a continental land mass, the North Pole is located in the middle of the Arctic Ocean amid waters that are almost permanently covered with constantly shifting sea ice. The sea depth at the North Pole has been measured at 4,261 m (13,980 ft) by the Russian Mir submersible in 2007 [ 1 ] and at 4,087 m (13,409 ft) by ...
The Drake Passage opened when Antarctica separated from South America due to plate tectonics, however, there is much debate about when this occurred, with estimates ranging from 49 to 17 million years ago (Ma). [8] [9] The opening had a major effect on the global oceans due to deep currents like the Antarctic Circumpolar Current (ACC).
Visualization of the ice and snow covering Earth's northern and southern polar regions Northern Hemisphere permafrost (permanently frozen ground) in purple. The polar regions, also called the frigid zones or polar zones, of Earth are Earth's polar ice caps, the regions of the planet that surround its geographical poles (the North and South Poles), lying within the polar circles.
Positioned asymmetrically around the South Pole and largely south of the Antarctic Circle (one of the five major circles of latitude that mark maps of the world), Antarctica is surrounded by the Southern Ocean. [note 2] Rivers exist in Antarctica; the longest is the Onyx.
America is also inscribed on the Paris Green Globe (or Globe vert) which has been attributed to Waldseemüller and dated to 1506–07: as well as the single name inscribed on the northern and southern parts of the New World, the continent also bears the inscription: America ab inuentore nuncupata (America, named after its discoverer).

For the 2007–2008 season, the TDRS relay (named South Pole TDRSS Relay or SPTR) was upgraded to support a data return rate of 50 Mbit/s, which comprises over 90% of the data return capability. [ 18 ] [ 19 ] The TDRS-1 satellite formerly provided services to the station, but it failed in October 2009 and was subsequently decommissioned.
After two winters frozen in the ice, without having achieved the goal of drifting over the North Pole, Amundsen decided to go to Nome to repair the ship and buy provisions. Several of the crew ashore there, including Hanssen, did not return on time to the ship. Amundsen considered Hanssen to be in breach of contract, and dismissed him from the ...
The North Pole lies in the Arctic Ocean while the South Pole is in Antarctica. North and South poles are also defined for other planets or satellites in the Solar System , with a North pole being on the same side of the invariable plane as Earth's North pole.
