Abstract: Increasing prevalence of anthropogenic activities (e.g. reclamation and dredging) in the coastal environment has resulted in elevated total suspended sediment (TSS) concentrations, impacting marine ecosystems. My thesis explores the impacts of these activities on the plankton community, beginning with a survey of the plankton and marine environment near two of the largest ongoing land reclamation projects in Singapore: Pulau Tekong and Tuas. I then experimentally investigated the impact of TSS on phytoplankton and zooplankton. Mesocosms were used to assess the effects of TSS concentration on a natural phytoplankton community. Using the copepod Acartia tonsa, TSS concentration, size and food availability were tested in combination to identify their effects on important biological functions. A. tonsa was also used to examine how TSS concentration and food availability affects swimming behaviour. My results shed light on the status of marine plankton in Singapore and act as a stepping-stone towards developing management tools for sediment pollution management.
