Importance Of Ocean Currents

It is defined as a movement in the oceans that has a direction and is continuous. These abiotic features of the environment are created by the average or mean flow of the seawater, winds, Coriolis Effect, salinity and temperature difference, cabbeling and breaking waves. Coriolis Effect is the result of the rotating Earth. The rotating Earth changes the straight line path of the current and winds as they travel. Thus, the currents due to this in the Northern part move to the right side whereas in the Southern Hemisphere they veer to the left. These are different from the tides because they are caused due to the gravitational pull of the Sun and the Moon. The direction and the strength of these currents are influenced by these factors as well …show more content…
If you travel with the currents you can reduce the costs of the fuel and hence reduce the costs of shipping. People competing in sailing competitions of people who used wind powered ships need to have the knowledge to make good use to increase and maintain optimum speed. An example of this in history is that of the Portuguese sailor that could not reach India due to Agulhas Current. Another importance of it is that it disperses many life forms like the European Eel lifecycle. In the polar and sub-polar areas the cold ocean currents bring planktons (food of fish). They are essential to continue the process of survival of certain marine species. This balances the marine ecosystem. They also affect the world’s temperature and regulate it. Certain ocean currents do not let ice from forming alone the coastal lines and brings up the warmer water to the North Atlantic. This helps shipping and travelling as the ships are not blocked from coming in and out. Countries can also use the current to generate hydroelectric power. Japan and Hawaii are already conducting tests and experiments for …show more content…
The Antilles current is directed northward and it flows to the east of the West Indies islands, ultimately forming the Sargasso Sea eddy. The Second branch called the Caribbean current joins the Gulf of Mexico and becomes the Gulf Stream.

2. South Equatorial Current (Warm):
South equatorial current is a continuation of the Benguela current and is steadier, stronger and of greater extent compared to the northern equatorial current. It flows from the western coast of Africa to the eastern coast of South America between the equator and 20° S latitude.
Like the northern equatorial current, this warm cur¬rent is also bifurcated into two branches due to the obstruction of land barrier in the form of the east coast of Brazil. The northward branch after travelling north-west merges with the north equatorial current near Trinidad while the second branch turns southward and contin¬ues as Brazil warm current parallel to the east coast of South America. The South Equatorial current is basically generated under the force of trade winds.
