Multi-scale Variability of Ecosystem Functioning in European and Chinese Shelf Seas

Continued global warming and ocean acidification are predicted with high confidence, while the direction and magnitude of changes of other atmospheric drivers (e.g. precipitation, wind) and nutrient loading are of high uncertainty and regionally dependent. Biogeochemical responses of coastal shelf seas to external drivers are often nonlinear, involving feedback that may amplify or dampen a perturbation imposed on the system. Coupled physical-biogeochemical process-based numerical models have proven useful in elucidating the mechanistic interplay and relative importance of the different factors contributing to ecosystem functioning with increasing realism. This research topic aims to understand and compare marine ecosystem functioning in Chinese and European shelf seas, based on studies that use state-of-the-art modeling and monitoring of coastal ecosystem dynamics.

This topic will enable more efficient knowledge share and distribution through a comparative assessment between distinct coastal shelf systems in China and Europe to further our understanding of complicated ecosystem dynamics in response to a changing climate and increasing anthropogenic pressure. It will allow us to better understand the sensitivity of coastal shelf ecosystem functioning to physical and biogeochemical perturbations, the role of shelf seas in global carbon cycling, and the resilience of Chinese and European shelf seas to ongoing and future changes in climate and anthropogenic activities.
