Research areas
The marginal seas’ eco-system is under substantial changes in the scenario of global climate variations. How had the marginal seas’ ecosystem been developing and been impacted by global climate variations are of the cutting-edge research areas in ocean sciences.
We focus on the analyzing the transmitting of variation signals of global climate change onto the marginal sea ecosystem via meso-/submeso-scale processes by means of of sedimentary records of biomarkers and their nitrogen/oxygen isotopes. We aim at resolving the temporal and spatial impacts of different-scale physical processes on biogeochemical processes.
