The "Eighty-Fifth Parallel" refers to a specific line of latitude located 85 degrees north of the equator. This parallel runs through the Arctic region, primarily over the Arctic Ocean and parts of northern landmasses. It is significant in geography and climate studies, as it marks a boundary where extreme polar conditions prevail. In terms of exploration, the Eighty-Fifth Parallel has been a point of interest for scientists and researchers studying climate change, polar ecosystems, and glacial movements. It is also relevant for navigation and mapping in the Arctic, contributing to our understanding of this remote and changing environment.
