Abstract : This paper is discussion of the author's emphasis on data assimilation in physical oceanography. The work draws on recent work by members of the MASIG Team. Our approach has focused on time-dependent models in which parameters are estimated through data assimilation using the variational adjoint method. It is useful to adapt a paradigm for classifying all data assimilation methods. I chose to define three groups of assimilation schemes: (A) local polynomial interpolation methods, (B) statistical (including optimal) interpolation methods, and (C) variational numerical analysis methods
