The lake is linked to the sea via a 2-km narrow canal that flows out from southwest.<br />

Water flows towa <br />

high, and vice versa. So the salinity <str<strong>on</strong>g>of</str<strong>on</strong>g> lake water varies seas<strong>on</strong>ally. The lake water gets<br />

fresher due to rainfall and the water carried via the drainage canals during winters,<br />

springs;; whereas lake water salinity. increases due to evaporati<strong>on</strong> and salt water inflow<br />

from the sea during summers. Salinity is higher in the part that has links to the sea and<br />

less in the northern parts, where leaking and drainage waters are effective. The lake<br />

water gets polluted because <str<strong>on</strong>g>of</str<strong>on</strong>g> the pesticides and fertilizer remnants carried by the<br />

drainage water. Akyatan Lago<strong>on</strong> is detected to have been highly polluted by the organic<br />

remnants carried from the drainage water <str<strong>on</strong>g>of</str<strong>on</strong>g> agriculture lands. The ground water is also<br />

recorded to have been polluted, a 1996 study reveals.<br />

Since the freshwater carried by the drainage canals freshens the lago<strong>on</strong> water, sea prey<br />

fish species such as sea bream cannot enter the lago<strong>on</strong>, local people note. According to<br />

them the water level and quality decreases due to the pesticides, fertilizer remnants and<br />

alluviums carried by the water canals.<br />

GEOLOGICAL ASPECTS<br />

The units formed in Akyatan Lago<strong>on</strong> and its immediate surroundings are divided into two<br />

tect<strong>on</strong>ic and stratigraphic groups such as Lower-Middle Miocene old Propylite Formati<strong>on</strong><br />

and Quaternary old units. Propylite Formati<strong>on</strong> is formed as a result <str<strong>on</strong>g>of</str<strong>on</strong>g> the intercalati<strong>on</strong> <str<strong>on</strong>g>of</str<strong>on</strong>g><br />

sandst<strong>on</strong>e, sandy limest<strong>on</strong>e and limest<strong>on</strong>e;; whereas Quaternary old units c<strong>on</strong>sist <str<strong>on</strong>g>of</str<strong>on</strong>g><br />

calishe, alluvial and sand dunes.<br />

BIOLOGICAL ASPECTS<br />

Habitats<br />

The <str<strong>on</strong>g>Ramsar</str<strong>on</strong>g> site comprises various habitats as open water surfaces, reed beds, fresh and<br />

saltwater swamps, freshwater puddles, p<strong>on</strong>ds, wide sand dune ecosystems and<br />

sandbanks.<br />

The lago<strong>on</strong> area shrinks in summers due to decrease in water amount feeding the lake<br />

and high evaporati<strong>on</strong>.<br />

The largest sand dunes <str<strong>on</strong>g>of</str<strong>on</strong>g> <str<strong>on</strong>g>Turkey</str<strong>on</strong>g> with an elevati<strong>on</strong> <str<strong>on</strong>g>of</str<strong>on</strong>g> 20 meters and a few kilometers<br />

in width are situated in the regi<strong>on</strong>, between Akyatan Lago<strong>on</strong> and the Mediterranean<br />

Sea. There are pits under sea level, situated am<strong>on</strong>g sand mounds that lie in row, which<br />

are filled with water during rainy periods. Ecologically important freshwater puddles and<br />

swamps that never dry located in the northeast <str<strong>on</strong>g>of</str<strong>on</strong>g> the sand dunes.<br />
