This paper describes the distribution of living coccolithophores (LCs) in the
Yellow Sea and the East China Sea in summer and winter, and its relationship
with environmental factors by canonical correspondence analysis (CCA). We
carried out a series of investigations on LCs distribution in the Yellow Sea
and the East China Sea in July and December 2011. 210 samples from different
depths were collected from 44 stations in summer and 217 samples were
collected from 45 stations in winter. Totally 20 taxa belonging to
coccolithophyceae were identified using a polarized microscope at the
1000 × magnification. The dominant species of the two seasons were
Gephyrocapsa oceanica, Emiliania huxleyi, Helicosphaera carteri, and
Algirosphaera robusta. In summer the abundance of coccolithophore cells and
coccoliths ranged 0–176.40 cells mL−1, and
0–2144.98 coccoliths mL−1, with the average values of
8.45 cells mL−1, and 265.42 coccoliths mL−1, respectively. And
in winter the abundance of cells and coccoliths ranged
0–71.66 cells mL−1, and 0–4698.99 coccoliths mL−1, with the
average values of 13.91 cells mL−1 and 872.56 coccoliths mL−1,
respectively. In summer, the LCs in surface layer were mainly observed on the
coastal belt and southern part of the survey area. In winter, the LCs in
surface layer had high value in the continental shelf area of section P. The
comparison among section A, section F, section P and section E indicated
lower species diversity and less abundance in the Yellow Sea than those in
the East China Sea in both seasons. Temperature and the nitrate concentration
may be the major environmental factors controlling the distribution and
species composition of LCs in the studying area based on CCA.
