Various Interesting Facts About the Atlantic Ocean


The Atlantic Ocean is a huge mass of water covering about 16.7-20 percent of the Earth and covers a total area of ​​approximately 85,133,000 square kilometers. To get a clear idea about its size, it is important to note that it is slightly greater than half of the Pacific Ocean.

This ocean has an average depth of 3.339 meters with adjacent seas and its volume is 354’700,000 cubic kilometers, with its adjacent seas. Milwaukee Deep is the deepest part of the Atlantic, measuring no more and no less than 8.380 meters.

It bounded on the north by the Arctic Ocean, the Pacific Ocean to the southwest, the southeast Indian Ocean, and the Southern Ocean or Antarctic south. It connects to the Arctic Ocean through the Denmark Strait, Greenland Sea, the Norwegian Sea and the Barents Sea. As for land, it washes the shores of America in the west and Europe and Africa in the east. It is “home” of the Baltic Sea, the Black Sea, the Caribbean Sea, the Mediterranean Sea, the Gulf of Mexico and the Norwegian Sea.

Truly northern waters sink because they are colder, dense and saltier than normal as a result of being cooled by the currents of the Arctic. This initiates what is known as “thermohaline circulation” or “ocean conveyor belt”.

There are many interesting things and facts about this world’s giant. We chose the crucial and most important 20+ facts of this ocean.

Properties of the Atlantic Ocean

  • The Atlantic is the saltiest ocean in the world, however, the surface salinity varies with latitude and season. Thus, the saltier waters are north latitude, 25 ° south in tropical areas of low rainfall and high evaporation. The lowest levels of salinity occur north of the Equator.
  • Temperatures can vary depending on the latitude and season, but are about -2 ° C. Again, warmer temperatures were recorded north of the Equator, while the lowest are concentrated in the Polar Regions.
  • Hurricanes are common between August and November, they tend to develop along the coasts of Africa and move westward into the Caribbean Sea.
  • In the Denmark Strait and the coast of the Baltic Sea, the water is usually covered with a lot of ice between October and June in the waters of Denmark Strait and Baltic Sea.

It is the main artery between Europe and America and has been sailed since many centuries ago. Atlantic Ocean has a large vessel traffic. At the same time, it has important oil and natural gas in sedimentary rocks of the continental shelves and especially in the Caribbean Sea, the Gulf of Mexico and the North Sea.

Besides oil and gas, the Atlantic is exploited for fisheries, sand, gravel, polymetallic nodules and precious stones.

The Atlantic Ocean has the pollution caused by oil spills, sewage water with toxic substances and wasted materials. Some international treaties are concerned about this and have joined forces to reduce the effects, although they have already endangered many animal species.
