Atlantic Meridional Overturning Circulation (AMOC)

I am currently working on research projects that focus on the Overturning in the Subpolar North Atlantic Program (OSNAP).  OSNAP is a trans-basin observing system, which is providing sustained measures of the full water-column volume, heat and freshwater transports at subpolar latitudes where warm saline waters of the subtropical origin meet cold fresh waters of the Arctic origin.  I am investigating the structure and variability of ocean circulations in the region (both overturning and gyre) and the mechanisms at which they vary and impact the heat and freshwater distributions.  I have been involved in the management and coordination of the OSNAP projects, and am leading the working groups on various issues related to the data management and analysis, as well as array optimization.

Inter-basin heat and freshwater exchanges

The ocean's role in our climate system stems from its capacity in transporting a large amount of heat and salt (or freshwater) across ocean basins.  I am investigating the spatial-temporal characteristics of the related transports and their potential feedback in a changing climate.  I am using observational records to constrain oceanic heat/salt redistributions, and to analyze the property changes in relation to ocean circulations.
