The 72nd Parallel North is a circle of latitude located 72 degrees north of the Earth's equatorial plane. It runs through the Arctic region, primarily over the Arctic Ocean, and passes near several islands, including parts of Greenland and Svalbard. This parallel is significant for navigation and climate studies, as it marks a boundary where the sun does not set during summer and does not rise during winter. Geographically, the 72nd Parallel North is important for understanding the effects of climate change in the Arctic. It is also relevant for wildlife habitats, as many species, such as polar bears and arctic foxes, thrive in this cold environment. The region is sparsely populated, with few human settlements, making it a unique area for scientific research.
