69th parallel north

The 69th parallel north is a circle of latitude that is 69 degrees north of the Earth's equatorial plane, in the Arctic. It crosses the Atlantic Ocean, Europe, Asia and North America, and passes through some of the southern seas of the Arctic Ocean.

At this latitude the sun is visible for 24 hours, 0 minutes during the summer solstice and Civil Twilight during the winter solstice.

70th parallel

70th parallel may refer to:

70th parallel north, a circle of latitude in the Northern Hemisphere

70th parallel south, a circle of latitude in the Southern Hemisphere

71st parallel north

The 71st parallel north is a circle of latitude that is 71 degrees north of the Earth's equatorial plane, in the Arctic. It crosses the Atlantic Ocean, Europe, Asia and North America, and passes through some of the southern seas of the Arctic Ocean.

At this latitude the sun is visible for 24 hours, 0 minutes during the summer solstice and Civil Twilight during the winter solstice.

Atmospheric circulation

Atmospheric circulation is the large-scale movement of air, and together with ocean circulation is the means by which thermal energy is redistributed on the surface of the Earth.

The Earth's atmospheric circulation varies from year to year, but the large-scale structure of its circulation remains fairly constant. The smaller scale weather systems – mid-latitude depressions, or tropical convective cells – occur "randomly", and long-range weather predictions of those cannot be made beyond ten days in practice, or a month in theory (see Chaos theory and Butterfly effect).

The Earth's weather is a consequence of its illumination by the Sun, and the laws of thermodynamics. The atmospheric circulation can be viewed as a heat engine driven by the Sun's energy, and whose energy sink, ultimately, is the blackness of space. The work produced by that engine causes the motion of the masses of air and in that process, it redistributes the energy absorbed by the Earth's surface near the tropics to the latitudes nearer the poles, and then to space.

The large-scale atmospheric circulation "cells" shift polewards in warmer periods (for example, interglacials compared to glacials), but remain largely constant as they are, fundamentally, a property of the Earth's size, rotation rate, heating and atmospheric depth, all of which change little. Over very long time periods (hundreds of millions of years), a tectonic uplift can significantly alter their major elements, such as the jet stream, and plate tectonics may shift ocean currents. During the extremely hot climates of the Mesozoic, a third desert belt may have existed at the Equator.

Cape Bathurst

Cape Bathurst (Inuit: Awaq) is a cape and a peninsula located on the northern coast of the Northwest Territories in Canada. Cape Bathurst is the northernmost point of mainland Northwest Territories and one of the few peninsulas in mainland North America protruding above the 70th parallel north. The first European to see the area was John Richardson, who also named it, in 1826. Some coast areas of Cape Bathurst are being eroded at a rate of 10 m (33 ft) a year.Baillie Island is located just off the coast of Cape Bathurst, separated from the peninsula by a 2 mi (3.2 km) shallow strait.

A notable nearby formation is Smoking Hills, a group of hills exhibiting continuous burning of oil shale deposits.

A rare endemic plant known as hairy rockcress or hairy braya (Braya pilosa, genus Braya of family Brassicaceae) is known to grow in five locations on Cape Bathurst as well as the nearby Baillie Islands. The plant is listed by the Northwest Territories Species at Risk Committee as threatened and by the Committee on the Status of Endangered Wildlife in Canada as endangered.

French Narval-class submarine

The Narval class (sous-marins d'escadre, "fleet submarines") were patrol submarines built for the French Navy in the 1950s.

Georg Carl Amdrup

Vice Admiral Sir Georg Carl Amdrup (Copenhagen, Denmark, November 19, 1866 – Copenhagen, January 15, 1947), RN was a Danish naval officer, Vice Admiral and Greenland researcher.

Parker's Notch

Parker's Notch, named after former Commissioner of the Northwest Territories, John Havelock Parker, is a protrusion of the Northwest Territories southwards into Nunavut on Victoria Island. In the Northwest Territories the protrusion is part of the Inuvik Region and the Kitikmeot Region in Nunavut.
