All of you might have seen the ocean currents at some or the other point in your lives. But do you know how they arise? Have you ever tried to find out about it? I am sure that most of you would not have tried to do so. But, don't worry; I will give you all the information regarding them. Ocean currents can be inviting and scary depending upon their frequency or strength of occurrence.
Major Ocean Currents
Arctic Ocean: Some of the major currents of the Arctic Ocean are the East Greenland current, Norwegian current, Beaufort gyre and the Transpolar drift. The East Greenland current originates in the Arctic Ocean and brings cold water along the eastern coast of Greenland. The Norwegian current flows north-easterly along the Atlantic coast of Norway at depths of between 50 and 100 meters.
The atmospheric flow produced by the subtropical high pressure systems drives the currents in these gyres. Smaller gyres occur in the North Atlantic and Pacific Oceans centered at 50° North. Currents in these systems are propelled by the circulation produced by polar low pressure centers. In the Southern Hemisphere, these gyre systems do not develop because of the lack of constraining land masses.
The ocean currents carry immense amount of energy and this is directly related to the density of water. Many Asian, European and North American countries are currently conducting studies and research to make use of the energy from ocean currents.
Ocean currents are important determinants of the climatic condition of a particular region. In fact, it has been postulated that we can obtain a lot of energy from these ocean currents.
