An example of assimilation technique for monitoring in marine environment

This work deals with application of assimilation method in investigation of phytoplankton distribution in particular to the stratified ocean. The measured data such as temperature, salinity as well as phytoplankton, are assimilated into the mathematical model, the typical diffusion and advection equation including biological process model, in terms of diffusion coefficient, advection velocity and biological parameter. The method is generalized as an optimizing problem in variant method and is examined in detail in estimating of empirical parameter, such as a diffusion coefficient.
