DETERMINATION OF SOME MACRO ELEMENT CONCENTRATIONS AND CHLOROPHYLL-A DISTRIBUTION IN A SHALLOW LAKE WETLAND (GÖKÇEADA SALT LAKE LAGOON, ÇANAKKALE/TURKEY)

In this study, the macro element concentrations and chlorophyll-a distribution in the Gokceada Salt Lake Lagoon which is in the category of Shallow Lake Wetland in Gokceada (Canakkale) were evaluated. For this purpose, some macro elements (Nitrite, Nitrate, Sulfate, Phosphate, Calcium, Magnesium, Potassium, and Phosphorus) and chlorophyll-a levels as well as water temperature and dissolved oxygen values were measured in 2016 as seasonally (January, May, August, November) from three stations.  During the autumn season, nitrite, nitrate, phosphate and sulfate values measured as 5.65 ppm; 16.9 ppm; 77 ppm; and 8547 ppm, respectively. As a result, the macro element concentrations deposited in the sediment and the chlorophyll-a amounts of the lake was signed to the ecological conditions are very suitable for the development of eutrophication. In the end of the study, some suggestions were done to protect the ecosystem balance.
