Editing Aegean Sea (section)

===Hydrography===
Aegean surface water circulates in a counterclockwise [[Ocean gyre|gyre]], with [[hypersaline]] Mediterranean water moving northward along the west coast of Turkey, before being displaced by less dense Black Sea outflow. The dense [[Mediterranean]] water sinks below the Black Sea inflow to a depth of {{convert|23|-|30|m}}, then flows through the [[Dardanelles Strait]] and into the [[Sea of Marmara]] at velocities of {{cvt|5|-|15|cm/s|in/s|0}}. The Black Sea outflow moves westward along the northern Aegean Sea, then flows southwards along the east coast of Greece.<ref>{{cite journal |last1=Aksu |first1=A.E. |last2=Yaşar |first2=D. |last3=Mudie |first3=P.J. |last4=Gillespie |first4=H. |title=Late glacial-Holocene paleoclimatic and paleoceanographic evolution of the Aegean Sea: micropaleontological and stable isotopic evidence |journal=Marine Micropaleontology |date=April 1995 |volume=25 |issue=1 |pages=1–28 |doi=10.1016/0377-8398(94)00026-J |bibcode=1995MarMP..25....1A }}</ref>

The physical oceanography of the Aegean Sea is controlled mainly by the regional climate, the fresh water discharge from major rivers draining southeastern Europe, and the seasonal variations in the Black Sea surface water outflow through the [[Dardanelles Strait]].

* '''Aegean Sea Surface Water'''&nbsp;– {{convert|40|-|50|m}} thick veneer, with summer temperatures of 21–26&nbsp;°C and winter temperatures ranging from {{convert|10|°C}} in the north to {{convert|16|°C}} in the south.
* '''Aegean Sea Intermediate Water'''&nbsp;– Aegean Sea Intermediate Water extends from {{convert|40|-|50|m|abbr=on}} to {{convert|200|-|300|m|abbr=on}} with temperatures ranging from {{convert|11|-|18|C}}.
* '''Aegean Sea Bottom Water'''&nbsp;– occurring at depths below {{convert|500|-|1000|m|abbr=on}} with a very uniform temperature ({{convert|13|-|14|C}}) and salinity (3.91–3.92%).
