About 3.5% of the weight of seawater comes from dissolved salts. But just how did the salt get in there? Why is the ocean salty? Lets dive in.
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 rather than temperature. In this way, the thermohaline circulation can be considered to have been less "thermo" and more "haline".
Doug Peltz, popularly known as Mystery Doug, is an American science communicator and entrepreneur based in San Francisco. He is best known as the co-founder of the popular science curriculum Mystery Science, a science program used in 50% of U.S. elementary schools and recently acquired by Discovery Education . [ 2 ]
Seawater, or sea water, is water from a sea or ocean.On average, seawater in the world's oceans has a salinity of about 3.5% (35 g/L, 35 ppt, 600 mM). This means that every kilogram (roughly one liter by volume) of seawater has approximately 35 grams (1.2 oz) of dissolved salts (predominantly sodium (Na +
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.

Pink lakes arise from a combination of factors, which include climate and hydrology of the continent beneath them, in particular the level of salinity.The orange/pink colour of salt lakes across the world has often been attributed to the green alga Dunaliella salina, but other work has shown that bacteria or archaea are also involved.
Deep ocean water is the name for cold, salty water found deep below the surface of Earth's oceans. Deep ocean water makes up about 90% of the volume of the oceans. Deep ocean water has a very uniform temperature of around 0-3 °C. Its salinity is about 3.5% or 35 ppt (parts per thousand). [3]
