The 85th Parallel North is a circle of latitude located 85 degrees north of the equator. It is situated in the Arctic region, primarily over the Arctic Ocean and parts of Greenland. This parallel is significant for scientific research, particularly in studying climate change and polar ecosystems. At this latitude, the sun does not set during the summer months, leading to continuous daylight, while in winter, it experiences polar night with extended periods of darkness. The 85th Parallel North is also important for understanding the habitats of various Arctic species, including polar bears and seals.
