The North American Arctic comprises North Canada, the northern portion of Alaska, and Greenland. This toolkit will focus on the North American Arctic, which contains North Canada and the northern part of Alaska. The North American Arctic lies above the Arctic Circle. The North American Arctic includes the Arctic Ocean, Hudson Bay, the Gulf of Alaska, and the North Atlantic Ocean. This region is home to various species of plants and animals characteristic of the Arctic region. The climate in this region is characterized by long, cold winters and short, cool summers. The Arctic ocean is largely surrounded by land, and therefore climate of the arctic region is controlled by the oceanic circulations in the north part.
