Surface Currents
Surface currents are water movements that take place on the top layer of the ocean and make up about 10 percent of the ocean's water. In most areas, surface currents make up the top 400 meters of the ocean, though this can vary due to tides, wind and weather conditions. They are caused primarily by wind and tend to develop rotational patterns. The location of these surface currents is heavily influenced by seasonal patterns.
Deep Water Currents
Deep water currents are water movement patterns that take place more than 400 meters below sea level. They are influenced by both ocean density and temperature changes. Cooler water has a higher salt density than warm water, so as currents flow through cool areas, the warmer water in that region rises and the cool water flowing into the area sinks. This pattern continues as water currents travel through broad temperature zones and climate regions. The rising and sinking water actions cause the movement we call currents.
