Where is the Arctic?
In the strictest sense, the Arctic is all of the Earth north of the Arctic Circle, which is located at 66 degrees, 32 minutes North Latitude. However, there are other definitions to suit specific scientific or political interests. For instance, the U.S. Congress has decreed that all of the Bering Sea, which extends southward to about 53 degrees North Latitude, is part of the Arctic for internal U.S. planning and budgeting purposes. Others make use of the such markers as the southernmost extent of winter sea ice for oceanic boundaries of the Arctic, or the treeline for terrestrial boundaries.
