Ocean Currents: An Overview

• Ocean currents are continuous, directed movements of ocean water generated by forces acting upon the water, such as wind, the Coriolis effect, temperature, and salinity differences.

• They play a crucial role in redistributing heat across the globe, significantly influencing regional and global climates.

• Ocean currents are broadly classified into two types based on their temperature:

  • Warm Currents: These originate from equatorial regions and flow towards polar regions, increasing the temperature of the coastal areas they pass.

  • Cold Currents: These originate from polar regions and flow towards equatorial regions, lowering the temperature of the coastal areas.

The Labrador Current: Location and Characteristics

• The Labrador Current is a well-known cold ocean current.

• It flows from the Arctic Ocean, moving southward along the coast of Labrador and Newfoundland in North America.

• Therefore, the Labrador Current is located entirely in the Northern Hemisphere.

• A notable feature of this current is the formation of dense fog when it meets the warm Gulf Stream off the Grand Banks of Newfoundland, an area also renowned for its rich fishing grounds.
