Using the adjoint of an ocean general circulation model, I try to understand the local and remote processes that generate temperature anomalies in the Nordic Seas on different timescales and their potential contribution to decadal climate predictability.
I furthermore use data assimilation techniques to assess observation systems for the reconstruction of modern and past ocean states. My PhD project is part of the ice2ice project, which studies Dansgaard-Oeschger (D-O) events, abrupt climate change events during the last glacial. I explore the capability of the globally available proxy data to constrain ocean circulation of the past, taking into account its sparsity and uncertainties. By means of Uncertainty Quantification I study which paleoclimate dynamics problems are most tractable.
