Arctic Ocean

"The Arctic Ocean is home to the North Pole, a hypothetical place where Christmas can spread the joys every year. I wonder if there's Santa Claus out there?"

--Su Ji-Hoon, Arctic War

The Arctic Ocean is the smallest and shallowest of the world's five major oceans. The International Hydrographic Organization (IHO) recognizes it as an ocean, although some oceanographers call it the Arctic Mediterranean Sea or simply the Arctic Sea, classifying it a mediterranean sea or an estuary of the Atlantic Ocean. Alternatively, the Arctic Ocean can be seen as the northernmost part of the all-encompassing World Ocean.
