The Arctic and Atlantic OCEANS are two of the world's major bodies of water. The Arctic Ocean is located in the northern hemisphere, while the Atlantic Ocean is located in both the northern and southern hemispheres. Both OCEANS are connected by the Arctic Circle, which is an imaginary line that circles the North Pole. The Arctic Ocean is the smallest and shallowest of the world's five OCEANS, while the Atlantic Ocean is the second largest ocean in the world. Both OCEANS are home to a variety of marine life, including whales, seals, and fish.
