The 80th Parallel North is a circle of latitude located 80 degrees north of the Earth's equator. It runs through the Arctic region, primarily over the Arctic Ocean and parts of the land masses of Greenland and Canada. This parallel is significant for climate studies, as it marks a boundary where temperatures are extremely low and ice coverage is prevalent. At the 80th Parallel North, the sun does not rise for a significant portion of the winter, leading to polar night conditions. Conversely, during summer, the area experiences continuous daylight, known as the midnight sun. This unique phenomenon affects the ecosystems and wildlife, including species like polar bears and arctic foxes.
