Abstract

During the MODUM project two independent methods for estimation of potential leakage of dumped chemical munitions in the Baltic Sea have been developed. The first one is Lagrangian tracking of particles with random disturbance. The second one is using a passive tracer as a marker of potential leakage. The approaches have been developed in open source ocean models adapted for the Baltic Sea. But the models are quite different. The walking particles approach has been developed in the Princeton Ocean Model, which is nonlinear, free surface, hydrostatic, σ-coordinate, with an imbedded second and a half moment turbulence closure sub-model. The passive tracer was implemented in the Parallel Ocean Program – a z-level coordinate, general circulation ocean model that solves 3-dimensional primitive equations for stratified fluid, using the hydrostatic and Boussinesq approximations. Because of many differences in our approaches we skipped a detailed comparison of the presented results (however, this will be the subject of the next stage in our work). Although the approaches and the models are quite different, the results are comparable.
