Distribution of Benthic Foraminifera in Surface Sediments of the Laizhou Bay, Bohai Sea and Its Environmental Significance
A total of 240 samples from surface sediments of the Laizhou Bay, Bohai Sea were quantitatively analyzed for benthic foraminifera. There are 42 common benthic foraminifera species found in these samples. The benthic foraminiferal fauna is dominated by hyaline group with an average abundance of 70.9%. The porcellaneous group is the second and arenaceous group is the least. Both abundance and diversity of benthic foraminifera show an increasing trend from the
