Simple ecosystem model of the central part of the East China Sea in spring

This paper's simple ecological model to simulate the ecosystem variation and the vertical carbon flux in the central part of the East China Sea in spring, inter—related the phytoplankton, zooplankton, autotrophic and heterotrophic bacterioplankton, nitrate, and dissolved organic carbon (DOC) in a run lasting 90 days. Except for DOC, because of poor observation precision, the major seasonal features of the vertical distribution for these components can be simulated by this model. The results show that spring bloom is just a short period of 1–2 weeks and that deposit carbon flux at the bottom interface is about 200 mg/m2· d in the first 20 days and then reaches its maximum of 1500 mg/m2· d about 2 months later after the spring bloom.
