Following are circles of latitude between the 80th parallel north and the 85th parallel north:
81st parallel north
The 81st parallel north is a circle of latitude that is 81 degrees north of the Earth's equatorial plane, in the Arctic. It crosses the Atlantic Ocean, the Arctic Ocean, Europe, Asia and North America.
At this latitude the sun is always visible during the summer solstice and astronomical twilight during the winter solstice.
Around the world
Starting at the Prime Meridian and heading eastwards, the parallel 81° north passes through:
82nd parallel north
The 82nd parallel north is a circle of latitude that is 82 degrees north of the Earth's equatorial plane, in the Arctic. It passes through the Arctic Ocean and North America. This is the first line of latitude in the Northern Hemisphere to only touch one continent.
At this latitude the sun is visible for 24 hours during the summer solstice and astronomical twilight during the winter solstice.
The world's northernmost continuously-inhabited settlement, the weather station and military facility of Alert in Nunavut, is closest to this parallel.
Around the world
Starting at the Prime Meridian and heading eastwards, the parallel 82° north passes through:
83rd parallel north
The 83rd parallel north is a circle of latitude that is 83 degrees north of the Earth's equatorial plane, in the Arctic. It passes through the Arctic Ocean and North America.
The northernmost land on earth, whether the permanent Kaffeklubben Island,1 or the shifting/resubmerging gravel banks of Oodaaq, ATOW1996, or 83-42, all of which are part of Greenland, are roughly 40 minutes of arc (75 to 79 kilometres) north of this parallel.
At this latitude the sun is visible for 24 hours during the summer solstice and astronomical twilight during the winter solstice.
Around the world
Starting at the Prime Meridian and heading eastwards, the parallel 83° north passes through:
84th and 85th parallels north
The 84th parallel north and the 85th parallel north are circles of latitude that are, respectively, 84 and 85 degrees north of the Earth's equatorial plane, in the Arctic. No land lies on either the 84th or 85th parallel north; they only lie on the Arctic Ocean; the 84th parallel is the first parallel by degree to do so. Regions north of the 84th parallel are excluded from UTM Zones.
The northernmost land on earth, Kaffeklubben Island, Greenland,2 is roughly 40 kilometres south of the 84th parallel.
At the 84th and 85th parallels, the sun is visible for 24 hours, 0 minutes during the summer solstice. During the winter solstice, the 84th parallel is under astronomical twilight, and the 85th parallel is under total nighttime during the entire day. The 85th parallel is the first parallel by degree to do this. The Arctic Circle is the latitude where the center of the sun is visible at midnight during the summer solstice, as opposed to the entire disk.
