This study aims to investigate both the distribution and character of particulate organic carbon (PIC) and particulate inorganic carbon (PIC) in the suspended sediment in the Gaoping estuary and its river plume. Furthermore, this study aims to investigate the tidal influence in the estuary and its plume by studying the size of sediment and the concentration of chlorophyll-a. In this study, suspended sediment, is mainly collected by multi-sieve filter, Catnet, which is used for the determinations of sediment size, organic carbon, inorganic carbon, as well as chlorophyll-a.
The result shows that fine particle (<10 £gm) contributes more than 50% of the total weight in 5 suspended sediment groups (>153, 63-153, 10-63, 3-10, and 0.7-3), indicating that the PIC and POC are mainly controlled by the amount of fine particle. This suggests that fine particle is the carrier of the PIC and the POC, thus distributions of PIC and POC will be influenced as concentrations of the fine particle is influenced by environmental factors.
In dry season, POC concentration is higher than in wet season; moreover, the concentration of POC beneath is higher than the surface, suggesting the influence of TSM. The distributions of suspended sediment are similar in both wet and dry seasons in size of <10 £gm, indicating there is no seasonal influence in the size of suspended sediment in our study areas. The PIC concentration in dry season is higher than the wet seasons, where the surface PIC concentration is higher than the beneath concentration in both dry and wet seasons, suggesting dissolution of PIC during settle down. The PIC mainly contributes by the fine particle (<10 £gm) which does not suffer any seasonal change. The TSM, POC, as well as PIC in suspended sediment in the Gaoping estuary and its plume are mainly contributed by fine particles. Distributions of these fine particles are highly influenced by the tides, but not the season changes. This study shows that the distributions of TSM, POC, as well as PIC in suspended sediments can be known through the characters of the suspended sediment.
