Calcareous nannofossil analysis have been carried out for 47 surface sediment samples taken from the southern parts of the Yellow Sea(120.5°~125.5°E,31.8°~37°N). The results show that the nannofossils are dominated by the typical marginal assemblages of Emiliania hexleyi
and Gephyrocapsa oceanica
. The total abundance of calcareous nannofossils varies between 0 and 1451, and is controlled by the water depth and the Yellow Sea Warm Current. The distribution of E.huxleyi
shows a different pattern. E.huxleyi
has a similar distribution with the total abundance of nannofossils:higher abundance in the central area and lower abundance in the coastal area. G.oceanica
, however, is more abundant in the western coastal area, but less in the sediments far from the coast.These results indicate that the distribution of E.huxleyi
were controlled mainly by the water depth and the Yellow Sea Warm Current, and the distribution of G.oceanica
is probably linked to the seawater nutrient.
