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 or the shifting/resubmerging gravel banks of Oodaaq, ATOW1996, or 83-42 are roughly 40 minutes of arc (75 to 79 kilometres) north of this parallel.
At this latitude the sun is visible for 24 hours, 0 minutes during the summer solstice and astronomical twilight during the winter solstice.

Above the 83rd parallel north
Areas above the 83rd parallel north include those that are 84 degrees north of the Earth's equatorial plane, in the Arctic to 90 degrees which define Earth's North Pole. No land lies above the 83rd parallel north except for the Arctic Ocean, which is covered by a Polar ice cap that varies in size.
