Aegean Sea Introduction: The Aegean Sea is located in the northeastern Mediterranean, between Greece and Turkey, and is connected to the Sea of ​​Marmara via the Dardanelles Strait. The Aegean Sea is 610 kilometers long from north to south and 300 kilometers wide from east to west. There are many islands, about 2,500, so it is also known as the "multi-island sea". The salinity of its seawater is relatively high, 36-39‰, which is higher than that of the Sea of ​​Marmara and the Black Sea. Therefore, the lighter seawater in the Black Sea flows from the surface through the strait into the Aegean Sea, while the seawater with higher salinity in the Aegean Sea passes through the lower layer of the strait. Flows to the Black Sea.
