Our group aims to better understand how the ocean works and how the ocean is affected by and responds to the ever-changing climate

We are a group of physical oceanographers in the School of Marine Science and Policy at the University of Delaware. Our research is mainly on the roles of the global ocean in the climate system. We are particularly interested in the connection and exchange between the upper and deep layers of the global ocean and their implications for climate change. Our previous and current research generally falls into two topics: 1) influences of mesoscale eddies on the physical, biological and geological processes in the deep ocean, and 2) vertical transport of heat, salt and other tracers and its variation with climate. Our studies are mainly carried out by analyzing in situ and satellite measurements, examining ocean synthesis products, and conducting numerical simulations.

I gave a department seminar talk at UD to review the activities of our group over the past few years. A recording of the talk can be found here https://capture.udel.edu/media/SMSP+Spring+2022+Colloquia+Speaker+Series+-+Dr.+Xinfeng+Liang/1_6g3ml806/187881983


Our paper on the western boundary current upwelling was selected as a Research Spotlight by AGU EOS https://eos.org/research-spotlights/hidden-upwelling-systems-may-be-overlooked-branches-of-ocean-circulation


After a long and bumpy journey, our paper on the upwelling associated with the major Western Boundary Currents was finally accepted in JGR-Oceans. We believe this upwelling is an overlooked branch of the global ocean circulation.
