Using the observed temperatures and salinities, in the modern ocean, is about 10 whilst at the LGM it is estimated to have been closer to 25. The modern thermohaline circulation is thus more controlled by density contrasts due to thermal differences, whereas during the LGM the oceans were more than twice as sensitive to differences in salinity ...
Deep ocean water (DOW) is the name for cold, salty water found in the deep sea, starting at 200 m (660 ft) 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; [1] in polar regions, the upper layers of ocean water are cold and fresh. [2]
Why the Sea Is Salt (Norwegian: Kvernen som maler på havsens bunn; the mill that grinds at the bottom of the sea) is a Norwegian fairy tale collected by Peter Christen Asbjørnsen and Jørgen Moe in their Norske Folkeeventyr. [1] Andrew Lang included it in The Blue Fairy Book (1889). [2]

The degree of salinity in oceans is a driver of the world's ocean circulation, where density changes due to both salinity changes and temperature changes at the surface of the ocean produce changes in buoyancy, which cause the sinking and rising of water masses.
Artistic interpretation of the Mediterranean geography during its evaporative drawdown, after complete disconnection from the Atlantic. The rivers carved deep gorges in the exposed continental margins; the concentration of salt in the remaining water bodies led to rapid precipitation of the salt.
Brine rejection is a process that occurs when salty water freezes. The salts do not fit in the crystal structure of water ice, so the salt is expelled. Since the oceans are salty, this process is important in nature. Salt rejected by the forming sea ice drains into the surrounding seawater, creating saltier, denser brine.
