The Arctic

Region, primarily made up of the frozen Arctic Ocean, that surrounds the North Pole. Land masses include islands and the northern parts of the European, Asian, and North American continents.

Area: 14.056 million sq. km (5.4 million sq. mi.), largely frozen ocean.

Geographic North Pole: Northern end of Earth's axis, located at about latitude 90°N.

Magnetic North Pole: Continues to shift and is located at approximately 82°N and 114°W in the Queen Elizabeth Islands of northern Canada.

Terrain: Central surface covered by a perennial drifting polar icepack that averages about 3 meters in thickness; the icepack is surrounded by open seas during the summer, but more than doubles in size during the winter and extends to the encircling landmasses.

Climate: Polar climate characterized by persistent cold and relatively narrow annual temperature ranges; winters characterized by continuous darkness, cold and stable weather conditions, and clear skies; summers characterized by continuous daylight, damp and foggy weather, and weak cyclones with rain or snow.

Regions: The Arctic is divided by the summer isotherm, a climatic boundary between regions with summer temperatures averaging 50°F (or 10°C)—the subarctic—and colder regions (the true Arctic).

Elevation extremes: Lowest point: Fram Basin –4,665 m. Highest point: sea level 0 m.
