Abstract

Preliminary results of faunal analysis of 149 northern South China Sea surface sediment grab samples collected from 7–1010 m depth, yielded some 250 species of agglutinated foraminifera belonging to 89 genera under 29 families. Agglutinated foraminifera are more densely distributed in the middle shelf to outer shelf regions than in near-shore and slope to bathyal regions. The distribution of relative abundance shows a reverse trend of higher percentage occurrence in near-shore, inner shelf, and bathyal regions than in the middle to outer shelf regions. Species number increases with water depth and different species composition characterizes different depth zones. Based on marked differences in species composition, 5 agglutinated foraminiferal assemblages characterizing inner shelf, middle shelf, outer shelf, shelf edge to slope, and bathyal depths are recognized.
