Salinity is a measure of the mass of dissolved solids, which consist mainly of salt. Increasing the salinity will increase the density. Just like the pycnocline defines the layer with a fast change in density, similar layers can be defined for a fast change in temperature and salinity: the thermocline and the halocline. Since the density ...
Entities called "seas" which are not divisions of the World Ocean are not included in this list. Excluded are: Lakes, ponds, etc.: Salt lakes with "Sea" in the name: Aral Sea, Dead Sea, Caspian Sea, Salton Sea; Freshwater lakes with "Sea" in the name: Sea of Galilee; Bodies of water identified in lakes (bays, straits, etc.) Ocean gyres
Salt marshes are a transition from the ocean to the land, where fresh and saltwater mix. [25] The soil in these marshes is often made up of mud and a layer of organic material called peat. Peat is characterized as waterlogged and root-filled decomposing plant matter that often causes low oxygen levels (hypoxia).
Annual mean sea surface salinity in Practical Salinity Units (psu) from the World Ocean Atlas [117] Salinity is a measure of the total amounts of dissolved salts in seawater. It was originally measured via measurement of the amount of chloride in seawater and hence termed chlorinity.
Once the salt structure has reached the surface, it is termed one of four names; salt-wing intrusions, extrusive advance, open-toed advance or thrust advance. [ 1 ] [ 2 ] There is a certain level of transition between the four, as some process, such as the dissolution and removal of salt, deposition of new sediment, erosion and thrusting can ...
A more comprehensive definition of an estuary is "a semi-enclosed body of water connected to the sea as far as the tidal limit or the salt intrusion limit and receiving freshwater runoff; however the freshwater inflow may not be perennial, the connection to the sea may be closed for part of the year and tidal influence may be negligible". [3]
Modern sea salt production is almost entirely found in Mediterranean and other warm, dry climates. [5] "Fleur de sel" sea salt, Île de Ré. Such places are today called salt works, instead of the older English word saltern. An ancient or medieval saltern was established where there was: Access to a market for the salt [6]
Oceanic crust is the thin layer of solidified volcanic basalt that covers the Earth's mantle. Continental crust is thicker but less dense. From this perspective, the Earth has three oceans: the World Ocean, the Caspian Sea, [citation needed] and the Black Sea. The latter two were formed by the collision of Cimmeria with Laurasia.
