2. Relating to or bordering the Atlantic Ocean.

A heat transfer from south to north by near-surface waters moving across the equator in the Atlantic Ocean.

It is an inhibition to the strength of this warming cukrrent. A disruption of this current caused by global warming could affect the relatively mild climate of northern Europe.

The world's second-largest of the world's five oceans (after the Pacific Ocean, but larger than the Indian Ocean, Southern Ocean, and Arctic Ocean).

The Kiel Canal (Germany), Oresund (Denmark-Sweden), Bosporus (Turkey), Strait of Gibraltar (Morocco-Spain), and the Saint Lawrence Seaway (Canada-US) are important strategic access waterways.

The decision by the International Hydrographic Organization in the spring of 2000 to delimit a fifth world ocean, the Southern Ocean, removed the portion of the Atlantic Ocean south of 60 degrees south latitude.

The Atlantic Ocean provides some of the world's most heavily trafficked sea routes, between and within the Eastern and Western Hemispheres.

Other economic activities include the exploitation of natural resources; such as, fishing, dredging of aragonite sands (The Bahamas), and production of crude oil and natural gas (Caribbean Sea, Gulf of Mexico, and North Sea).
