| Research Abstract |
Coupling of silicon dynamics and carbon biogeochemical cycles in the euphotic zone was studied in the western subarctic Pacific Ocean and the East China Sea. Productions of particulate organic carbon and biogenic silica by phytoplankton assemblage and their export to the subsurface layers were affected by availabilities of trace elements such as iron and zinc. Characteristic of dominant diatom species was another important factor that controls balance between carbon and silicon fluxes in the euphotic zone.
