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]
Oceans and marginal seas as defined by the International Maritime Organization. The sea is the interconnected system of all the Earth's oceanic waters, including the Atlantic, Pacific, Indian, Southern and Arctic Oceans. [1] However, the word "sea" can also be used for many specific, much smaller bodies of seawater, such as the North Sea or the ...
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 water across the northern Atlantic Ocean becomes so dense that it begins to sink down through less salty and less dense water. This downdraft of heavy, cold and dense water becomes a part of the North Atlantic Deep Water, a southgoing stream. [29] Winds drive ocean currents in the upper 100 meters of the ocean's surface.
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.
The oxygen content in bottom water is high due to ocean circulation. In the Antarctic, salty and cold surface water sinks to lower depths due to its high density. As the surface water sinks, it carries oxygen from the surface with it and will spend an enormous amount of time circulating across the seafloor of ocean basins.
Annual mean sea surface salinity for the World Ocean. Data from the World Ocean Atlas 2009. [1] International Association for the Physical Sciences of the Oceans (IAPSO) standard seawater. Salinity (/ s ə ˈ l ɪ n ɪ t i /) is the saltiness or amount of salt dissolved in a body of water, called saline water (see also soil salinity).
The oceans are not just a marine habitat. They are also a workplace, a highway, a prison, a grocery store, a trash can, a cemetery — and much more. Why we need to think about the oceans differently
