Arctic Ocean

The Arctic Ocean, located mostly in the north polar region, is the smallest of the world's five oceans, and the shallowest. Even though IHO recognizes it as an ocean, oceanographers may call it the Arctic Mediterranean Sea or simply the Arctic Sea, classifying it as one of the mediterranean seas of the Atlantic Ocean.

Environment - current issues

Endangered marine species include walruses and whales; fragile ecosystem slow to change and slow to recover from disruptions or damage; thinning polar icepack; seasonal hole in ozone layer over the North Pole.

Reduction of the area of Arctic sea ice will have an effect on the planet's albedo, thus possibly affecting global warming. Many scientists are presently concerned that warming temperatures in the Arctic may cause large amounts of fresh, Arctic Ocean meltwater to enter the North Atlantic, possibly disrupting global ocean current patterns. Potentially severe changes in the Earth's climate might then ensue.
