Foraminifera preserved in sediment core act as a good indicator for assuming past
climatic changes. A sediment core was collected from South China Sea (SCS) near
Kelantan offshore which was located in the east coast of Peninsular Malaysia. The
present study aimed to understand the distribution abundance of foraminifera
assemblages in the sediment core. From this study, the foraminifera assemblages
showed significant changes at different depth in terms of abundance and diversity. A
total of 22 benthic foraminifera genera was identified as their relative abundance was
exceeding more than 2% of assemblages. The core was dominated by Ammonia spp.
meanwhile, Elphidium spp., Heterolepa spp., Bolivina spp. and Pseudorotalia spp.
were considered as common genera. Besides that, TOC and CaCO3 also showed
variations down the core. There was lack of correlation between Textularia spp. with
CaCO3 in this core. The low diversity of foraminifera could be related with an
environmental factors and post depositional changes.
