Movement of cold salty ocean water

Deep ocean water (DOW) is the name for cold, salty water found deep below the surface of Earth's oceans. Ocean water differs in temperature and salinity. Warm surface water is generally saltier than the cooler deep or polar waters; in polar regions, the upper layers of ocean water are cold and fresh. Deep ocean water makes up about 90% of the volume of the oceans. Deep ocean water has a very uniform temperature, around 0-3 °C, and a salinity of about 3.5% or, as oceano… Nettet31. mar. 2013 · Slight changes in salinity can change the density of ocean water. More saline water is denser than water with fewer salts. Changes in temperature can affect the ocean as well. Cold, salty water is denser than warmer, fresher water, and can sink beneath it, which can influence the movement of ocean water (currents).

NettetWhere does ocean water go? All this heating and cooling and melting and thawing creates a layered ocean: warmer fresher water on top, cold salty water at the bottom. Organisms move from one layer to another, and plant and animal remains containing nutrients "rain" down, but the layers stay fairly separate in all but a few places. NettetThe ocean (also the sea or the world ocean) is the body of salt water that covers approximately 70.8% of the Earth and contains 97% of Earth's water.

In cold, polar regions, changes in salinity affect ocean density more than changes in temperature. When salt is ejected into the ocean as sea ice forms, the water's salinity increases. Because salt water is heavier, the density of the water increases and the water sinks.
