Numerical ocean circulation models and biogeochemical models have reached a certain competence level, which is difficult to advance using conventional approaches of the oceanographic numerical modelling. Same time the numbers of in situ and remote observation datasets has increased over time, making it feasible to develop AI aided data integration algorithms which would improve the understanding of the ocean dynamics and further help to reduce the uncertainties of the numerical models. Hereby, our research group is taking a step forward by combining machine learning methods and algorithms in improving the performance of the numerical oceanographic models. The machine learning method has shown potential to identify significant dynamical features in the ocean model dynamics and allocate the uncertainties in time and space, which are further necessary for the data integration.
