The Sixty-Eighth Parallel is a circle of latitude located 68 degrees north of the Equator. It runs through several countries, including parts of Norway, Sweden, and Russia. This parallel is significant in geography as it marks the boundary of the Arctic region, where the climate is predominantly cold and harsh. In the context of Arctic exploration, the Sixty-Eighth Parallel has been a reference point for scientists and explorers studying the effects of climate change and the unique ecosystems found in these northern latitudes. It also plays a role in discussions about territorial claims and resource management in the Arctic.
