Ocean temperatures depends on the amount of solar radiation falling on its surface. In the tropics, the temperature of the surface layers can rise to over while near the poles the temperature in equilibrium with the sea ice is about . Deep seawater has a temperature between and in all parts of the globe. There is a continuous circulation of water in the oceans . An ocean current is a continuous, directed movement of seawater generated by a number of forces acting upon the water, including wind, the Coriolis effect, temperature and salinity differences. Ocean currents have different origins, such as tidesfor tidal currents, or wind and waves for surface currents . The global pattern of winds or atmospheric circulation creates a global pattern of ocean currents driven by the wind and the effect the circulation of the earth or the coriolis force. Theses major ocean currents include the Gulf Stream, Kuroshio current, Agulhas current and Antarctic Circumpolar Current. Collectively, currents move enormous amounts of water and heat around the globe. This circulation has important impacts on global climate and the uptake and redistribution of pollutants such as carbon dioxide by moving these contaminants from the surface into the deep ocean.
Ocean temperatures depend on the amount of solar radiation reaching the ocean surface. In the tropics, surface temperatures can rise to over . Near the poles, where sea ice forms, the temperature in equilibrium is about . Deep seawater temperature is between and in all parts of the ocean. Water continuously circulates in the oceans creating ocean currents which are directed movements of seawater. Currents are generated by a number of forces acting upon the water, including wind, the Coriolis effect, temperature and salinity differences. Tidal currents originate from tides, while surface currents are caused by wind and waves .
