This pressure ridge at the North Pole is about 1 km (0.62 mi.) long, formed between two ice floes of multi-year ice. The North Pole, also known as the Geographic North Pole, Terrestrial North Pole or 90th Parallel North, is the point in the Northern Hemisphere where the Earth's axis of rotation meets its surface.
Polar regions of Earth. 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. These high latitudes are dominated by floating sea ice covering much of the Arctic Ocean in the ...
The geomagnetic north pole is the northern antipodal pole of an ideal dipole model of the Earth's magnetic field, which is the most closely fitting model of Earth's actual magnetic field. The north magnetic pole moves over time according to magnetic changes and flux lobe elongation [2] in the Earth's outer core. [3]
True north (also called geodetic north or geographic north) is the direction along Earth 's surface towards the place where the imaginary rotational axis of the Earth intersects the surface of the Earth. That place is called the True North Pole. True south is the direction opposite to the true north. North per se is one of the cardinal ...
t. e. The Arctic Ocean is the smallest and shallowest of the world's five oceanic divisions. [1] It spans an area of approximately 14,060,000 km 2 (5,430,000 sq mi) and is the coldest of the world's oceans. The International Hydrographic Organization (IHO) recognizes it as an ocean, although some oceanographers call it the Arctic Mediterranean ...
North Polar ice cap melting. Earth's North Pole is covered by floating pack ice (sea ice) over the Arctic Ocean. Portions of the ice that do not melt seasonally can get very thick, up to 3–4 meters thick over large areas, with ridges up to 20 meters thick. One-year ice is usually about 1 meter thick. The area covered by sea ice ranges between ...
Relationship of Earth's axial tilt (ε) to the tropical and polar circles. The Arctic Circle is the southernmost latitude in the Northern Hemisphere at which the centre of the Sun can remain continuously above or below the horizon for twenty-four hours; as a result, at least once each year at any location within the Arctic Circle the centre of the Sun is visible at local midnight, and at least ...
Anauakaq (1906–1987; by Akatingwah) Matthew Alexander Henson (August 8, 1866 – March 9, 1955) was an African American explorer who accompanied Robert Peary on seven voyages to the Arctic over a period of nearly 23 years. They spent a total of 18 years on expeditions together. [1] He is best known for his participation in the 1908–1909 ...
