Invisible to us terrestrial creatures, an underwater current circles the globe with a force 16 times as strong as all the world's rivers combined [source: NOAA: "Ocean" ]. This deep- water current is known as the global conveyor belt and is driven by density differences in the water. Water movements driven by differences in density are also known as thermohaline circulation because water density depends on its temperature thermo and salinity haline. Density refers to an object's mass per unit volume, or how compact it is. A heavy, compact bowling ball is obviously going to be denser than an air-filled beach ball.

The ocean currents known since antiquity are called surface currents.

An ocean current is a continuous, directed movement of sea water generated by a number of forces acting upon the water, including wind , the Coriolis effect , breaking waves , cabbeling , and temperature and salinity differences. Depth contours , shoreline configurations, and interactions with other currents influence a current's direction and strength. Ocean currents are primarily horizontal water movements. More specifically, ocean currents influence the temperature of the regions through which they travel. For example, warm currents traveling along more temperate coasts increase the temperature of the area by warming the sea breezes that blow over them. Perhaps the most striking example is the Gulf Stream , which makes northwest Europe much more temperate than any other region at the same latitude. Other example is Lima, Peru , where the climate is cooler, being sub-tropical, than the tropical latitudes in which the area is located, due to the effect of the Humboldt Current.



How Ocean Currents Work

Red arrows indicate surface water currents and blue arrows indicate deep water currents. Thermohaline circulation drives deep ocean circulation. Thermo means heat and haline refers to salinity.

    The ocean currents known since antiquity are called surface currents. The majority of the ocean's currents take the form of a temperature- and salinity-driven "conveyor belt" that slowly churns water within the abyssal depths. Unlike the wind-driven surface currents, deep water.
