Role functions

Details for: Wei-Jun Cai

Dr. Wei-Jun has worked on the area of marine carbon cycling for over 20 years. His research areas include, in early days, CaCO3 dissolution and sediment diagenesis in sea floor using microelectrodes (O2, pH and pCO2) and, since 1998, air-sea exchange of CO2 and carbon cycling in coastal oceans. Most recently, his research focuses on the responses of coastal ocean carbon cycle and ecosystem to a changing terrestrial export of carbon and nutrients, interactions between coastal ocean acidification and other environmental stressors, and coral calcification mechanisms and its responses to ocean acidification.
