| Abstract: | Dinoflagellate cysts in the surface sediment collected in 2009 and 2010 were analyzed at 15 stations in the northern Yellow Sea. Twenty-eight dinoflagellate cyst taxa of thirty genera and two uncertain taxa were identified from samples. The dominant taxa were Gonyaulax spp. (Spiniferites spp.), Alexandrium catenella / tamarense and Alexandrium minutum / affine. The total cyst abundance ranged between 545 cysts/g DW and 3567 cysts/g DW, and the average was 1269 cysts/g DW. The total cyst abundance showed a decrease from the central sea area to the surrounding sea area. The distribution of dinoflagellate cysts in the northern Yellow Sea was correlated to the sediment grain size and hydrodynamics. The cysts of two toxic dinoflagellate species (Gonyaulax spinifera and Lingulodinium polyedrum), which produce Yessotoxin, and the cysts of three toxic dinoflagellate species (Alexandrium catenella / tamarense, Alexandrium minutum / affine and Gymnodinium catenatum), which produce paralytic shellfish poisoning (PSP), were distributed in the northern Yellow Sea. The living cysts of Alexandrium spp. were denser and more widely distributed in the northern Yellow Sea. It indicates the potential possibility of red tide occurrence in the northern Yellow Sea. |
