}} Akyatan Lagoon is a 14700-hectare wetland ecosystem that is designated as Wetland of International Importance by Ramsar Convention. A major stop over for migrating birds, Akyatan is recognized as an Important Bird Area by BirdLife International. It is the single largest green turtle rookery at the Mediterranean, holding 43% of the Mediterranean nesting population.〔Dr Max Kasparek, MEDASSET(Green turtle Chelonia mydas In Turkey) (Report to the 24th Meeting of the Standing Committee of the Convention on the Conservation of European Wildlife and Natural Habitats), pp. 6〕 The lagoon is located at the northeastern edge of Mediterranean Sea, 30 km south of the city of Adana, in Çukurova region of Turkey. The entrance to the lagoon is either from Tuzla or through Küçük Karataş Village. ==Geology== Akyatan lake and the lagoons were formed during the 4th era (10,000 years ago) when water levels at the Mediterranean started changing. As the rivers that make the delta flooded, a large swamp came into being at the location where there is Akyatan lake. The swamp then disconnected from the sea and took its shape today with the sand brought by the waves that formed a cord. It is a typical alluvial dam lake. With the decrease in the amount of water that feeds the lake and with high levels of evaporation, the area of the lake shrinks during summer. At the dried areas, mud surfaces form and by the end of summer the lake completely dries. Mud surfaces are seen especially at the west and northeast part of the lake. Around Kapı village, some islets reach the land. The lake has a connection to the sea through a 2 km narrow canal on the southwest side. There is a flow of water from the canal to the sea, when the water levels of the lake is high. When the water levels on the lake is low, the flow is from the sea to the lake. This results in the salt ratio of the lake varying throughout the year. In winter and spring, the lake water is fresh with rain and the waters carried by drainage canals. In the summer time, lake is very salty due to the high evaporation and the water flow from sea to the lake. Also, salt ratio is high at the areas close to the sea connection, and low at the northern sections of the lake where the drainage waters and leakage is effective. Turkey's largest sand dunes are in the area between the lake and the sea. The dunes extend as wide as 3 kilometers and rise as high as 20 meters. In between the dune hills, that line up along the coast, depression goes below the sea level. At the shores of the lake, there are swamps and reedbeds which vary in size depending on the fresh water leakage. North of the lake is surrounded with vast farmland. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Akyatan Lagoon」の詳細全文を読む スポンサード リンク
