Diatom flora and environmental factors in some fresh water ponds of East Ongul Island
Diatom flora and chemical factors of water in sixteen ponds of East Ongul Island, which are 10-100 meters in diameter and less than 2 meters in depth, were investigated from January 7 to 21, 1974. The obtained results are as follows; pH value - 6.7-7.2, chlor ion concentration - 49.0-860 ppm, chemic...
