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.
Starting at the Prime Meridian and heading eastwards, the parallel 81° north passes through:

The 77th parallel north is a circle of latitude that is 77 degrees north of the Earth's equatorial plane, in the Arctic. It crosses the Atlantic Ocean, Europe, Asia, the Arctic Ocean and North America. It is the northernmost integral parallel that passes through continental mainland.
The 78th parallel north is a circle of latitude that is 78 degrees north of the Earth's equatorial plane, in the Arctic. It crosses the Atlantic Ocean, Europe, Asia, the Arctic Ocean and North America. It is the southernmost integral parallel north that does not pass through any continental mainland.
