To understand how monsoonal forcing controls biogeochemical cycles in the SCS and how ENSO modulation of the monsoon strength influences it.
To monitor how the episodic events, such as typhoons or mesoscale eddies, affect biogeochemical processes in the upper water column.
To link the present day biogeochemical processes with paleorecords preserved in sediment cores taken by IMAGES and the Ocean Drilling Project for better understanding of the effect of climate change on the ocean biogeochemistry in the marginal sea.
