Abstract

Marine ecosystems are an important part of the global climate system. The growth and competition of phytoplankton in the ecosystem can affect the exchange of carbon dioxide and other trace gases between sea and air, thus regulating the Earth's climate. Therefore, understanding these processes and their feedback on climate change is critical. Marine plankton is an important player in the marine trace element cycle, but it is not fully represented in the Earth system model.Here I will illustrate the effects of marine ecological dynamics on the biogeochemical cycle: (1) the effects of marine ecosystem processes on ocean carbon sinks and sea-gas carbon dioxide fluxes in the context of climate change;(2) the effects of phytoplankton on marine dimethyl sulfide emissions and subsequent effects on cloud radiative forcing.

Presenter Profile

Prof. Wang Shanlin is currently working at the School of Ocean and Earth, Xiamen University, and the State Key Laboratory of Offshore Marine Environmental Science.She was one of the core members of the marine ecosystem module development team in two US Earth system models. She was responsible for the development and scientific application of marine ecosystems and biogeochemical modules in the Earth system model, with a particular focus on developing and researching biogeochemical coupling of the ocean to other layers.A number of studies have been carried out on phytoplankton competition mechanism, community structure, primary productivity, spatial and temporal changes in air-sea CO2exchange, and anthropogenic carbon storage.？
