WebJan 19, 2024 · Deep Water Circulation is also called ‘thermohaline’ circulation because of the role of heating, cooling, freshening, and salification in producing regional density differences within the ocean. The slow and deep water circulation is largely driven by … WebUPSC 2024. Currents are distinct and generally horizontal flows of a mass of water in a fairly defined’ direction. Currents are formed due to the density of water rotation of the earth and planetary winds. These currents form a clockwise pattern in the northern hemisphere and move in an anti-clockwise pattern in the southern hemisphere.
WebApr 8, 2024 · 1.Henry Stommel and Arnold Arons in 1960 first developed the theory of thermohaline circulation pattern. 2.The term thermohaline can be divided into two parts “thermo” and “haline” which refer to temperature and salt content respectively. 3.Sometimes temperature difference makes such kind of flow of seawater in a horizontal direction also. WebJan 16, 2024 · What is Deep Water Circulation (DWC)? About: It refers to the movement of water in the deep ocean. It is driven by the density differences between water masses caused by variations in temperature and salinity. In the Earth's polar regions ocean water gets very cold, forming sea ice.
WebJan 14, 2016 · The ocean currents may be classified based on their depth as surface currents and deep water currents: surface currents constitute about 10 per cent of all the water in the ocean, these waters are the upper 400 m of the ocean; deep water currents make up the other 90 per cent of the ocean water. Webwater mass, body of ocean water with a distinctive narrow range of temperature and salinity and a particular density resulting from these two parameters.
