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 ...
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).
Deep sea water column. The (oceanic) water column is a concept used in oceanography to describe the physical (temperature, salinity, light penetration) and chemical (pH, dissolved oxygen, nutrient salts) characteristics of seawater at different depths for a defined geographical point.
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 ...
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.
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
The name comes from the Ancient Greek word βένθος (bénthos), meaning "the depths". [1] Organisms living in this zone are called benthos and include microorganisms (e.g., bacteria and fungi) [2] [3] as well as larger invertebrates, such as crustaceans and polychaetes. [4]

A marine layer is an air mass that develops over the surface of a large body of water, such as an ocean or large lake, in the presence of a temperature inversion.
