**Numerical** solving the problem of detecting of ultraweak diffractors in a complex acoustical medium

... Time Datuming (RTD) and Common Scattering Point (CSP). The first procedure (RTD) extends (synthetic) wave field from the day surface down to some level that is sufficiently close to diffractors. Then the diffractors are determined by CSP-method. The **numerical** **model** of an acoustical medium and synthetic data were obtained in Shell company. Further processing has been performed in RIAIMG of Immanuel Kant Baltic Federal University.

#### A study into the passive tracer and Lagrangian particles propagation in the coastal area of South-East Baltic

This paper studies the passive tracer and Lagrange particle propagation in the coastal area of South-East Baltic using hydrodynamic **numerical** **modelling**. The inclusion of an additional parameter, which describes the variation of the passive tracer concentration as well as its connection with the Lagrange particle random walk **model**, into the **model** made it possible to identify the features of ...
