The Seventy-Fifth Parallel North is a circle of latitude located 75 degrees north of the equator. It runs through the Arctic region, primarily over the Arctic Ocean and parts of Greenland. This parallel is significant for navigation and climate studies, as it marks a boundary where the sun does not set during summer months and does not rise during winter months. Geographically, the Seventy-Fifth Parallel North crosses several countries, including Norway and Russia. It is also near the North Pole, making it an important reference point for researchers studying polar ecosystems and climate change.
