The spatial distribution of modern dinoflagellate cysts was studied, with the purpose of understanding the impact from
industrial pollution and sediment characteristics. Eight surface sediment samples were collected to analysis of the spatial
distribution of dinoflagellate cysts from two industrially polluted areas: Aliağa and Nemrut Bay (Eastern Mediterranean). A
total of 42 dinoflagellate cyst morphotype were identified and total cyst abundance ranged between 11 and 2543 cyst g-1 dry
weight sediment at sampling points. The cyst assemblages were represented by cyst of Gymnodinium nolleri, Alexandrium
affine type and Lingulodiniumma chaerophorum. The higher cyst concentration was recorded at mostly Aliağa Bay stations
however the higher cyst diversity was found at Nemrut Bay stations. Total cyst concentration and autotrophic cyst
concentration indicated metal pollution in the sampling areas whereas total number of cysts had no correlation with any metal
levels in the sediment except Cr. The distribution of dinoflagellate cysts also showed correlation with sediment structure in
Aliağa and Nemrut Bay.
