DHIs marine 2d and 3d models MIKE 21/3 are capable of modelling flow and physical processes like sand transport, bacterial plumes, oil spill etc. A data assimilation module for MIKE 21/3 has been developed 10 years ago and developments have been sparse since then, but recently it has been given new life and a lot of attention in the FP7-LOTUS project and NordForsk EmblA Center of Excellence. The new developments include parallelization with MPI, assimilation of track data (e.g. satellite altimetry), Ensemble OI and localization in space and time. This talk will give a brief introduction to MIKE 21/3 and its data assimilation module, it will highlight some of the recent DA developments and give some examples of its use in the Adriatic and North Sea.
