The "Eighty-Seventh Parallel" refers to a specific line of latitude located at 87 degrees north of the equator. This parallel is situated in the Arctic region, primarily over the Arctic Ocean and parts of the surrounding landmasses. It is significant in geographical studies and climate research, as it helps define the boundaries of polar ecosystems. In the context of geography, the Eighty-Seventh Parallel is often used as a reference point for mapping and navigation. It plays a role in understanding the effects of climate change in polar regions, where temperatures are rising faster than in other parts of the world.
