3. MEDSLIK-II general description The oil spill model code MEDSLIK-II, based on its precursor oil spill model MEDSLIK is a freely available community model  MEDSLIK-II uses a Lagrangian representation of the oil slick  MEDSLIK-II predicts the transport and oil transformation processes due to complex physical processes occurring at the sea-water interface  MEDSLIK-II includes a proper representation of high frequency currents, the wave induced currents and wind fields in the advective components of the Lagrangian trajectory model

10. ADVECTION - DIFFUSION TRANSFORMATIONS Advection-diffusion is solved using a Lagrangian approach: the oil slick is discretized by PARTICLES, which are TRANSPORTED by the water currents, waves and the turbulent diffusion. Transformation processes are solved considering the entire slick volume, subdivided in a thin and thick part (Mackay, 1980).
