I am currently working on applying an inverse model to the problem of diagnosing circulation and mixing in the subpolar North Atlantic, My work contributes to the Overturning in the Subpolar North Atlantic Program (OSNAP).
My PhD research was on diapycnal mixing in the Southern Ocean, with particular focus on the Drake Passage region. Working as part of the DIMES (Diapycnal and Isopycnal Mixing Experiment in the Southern Ocean), I modelled the DIMES tracer in three dimensions using an offline version of the MITgcm and observation-based velocity fields from the SatGEM product. Model outputs were compared with the tracer observations and used to establish whether the mixing measured by the tracer is consistent with microstructure and lee wave theory.
