Editing Mediterranean seas (section)

== List of mediterranean seas by type ==
There are two types of mediterranean sea.

=== Concentration basin ===
A '''concentration basin''' has a higher salinity than the outer ocean due to evaporation, and its water exchange consists of inflow  of the fresher oceanic water in the upper layer and outflow of the saltier mediterranean water in the lower layer of the connecting [[channel (geography)|channel]].

* The [[Mediterranean Sea|Eurafrican Mediterranean Sea]] (a concentration basin as a whole, but the Adriatic Sea and the Black Sea are dilution basins (see below) owing to the [[Po (river)|Po River]], and the [[Danube]], [[Dnieper]], and [[Don (river)|Don]] rivers respectively)
* The [[Persian Gulf]]
* The [[Red Sea]]<ref>{{Cite journal |last1=Sofianos |first1=Sarantis S. |last2=Johns |first2=William E. |date=2007 |title=Observations of the summer Red Sea circulation |url=http://dx.doi.org/10.1029/2006jc003886 |journal=Journal of Geophysical Research: Oceans |volume=112 |issue=C6 |doi=10.1029/2006jc003886 |bibcode=2007JGRC..112.6025S |issn=0148-0227}}</ref>

=== Dilution basin ===
A '''dilution basin''' has a lower salinity due to freshwater gains such as rainfall and rivers, and its water exchange consists of outflow of the fresher mediterranean water in the upper layer and inflow of the saltier oceanic water in the lower layer of the channel. Renewal of deep water may not be sufficient to supply [[oxygen]] to the bottom.

* The [[Adriatic Sea]]
* The [[American Mediterranean Sea]]
* The [[Arctic Ocean]] (a.k.a. the ''Arctic Mediterranean Sea'')
* The [[Australasian Mediterranean Sea]]
* [[Baffin Bay]]
* The [[Baltic Sea]]
* The [[Black Sea]]
