Overview of the North Atlantic Ocean
The North Atlantic Ocean is the northern part of the Atlantic Ocean, stretching roughly from the Arctic Ocean in the north to the equator in the south. Covering approximately 41 million square miles (106 million square kilometers), it is the second-largest ocean basin on Earth. Its boundaries are generally defined by the continents of North and South America to the west, Europe and Africa to the east, the Arctic Ocean to the north, and the South Atlantic Ocean to the south.
Geographical Boundaries and Key Coordinates
- Northern Boundary: Arctic Ocean, characterized by icy waters and the Greenland Sea.
- Western Boundary: North and South American continents, including countries like the United States, Canada, and Brazil.
- Eastern Boundary: Europe (including the UK, Norway, and Iceland) and Africa (notably Morocco and Senegal).
- Southern Boundary: The equator, where the North Atlantic transitions into the South Atlantic.
