IMPACT WAVES IN NONHOMOGENEOUS PELAGIC EC OSYSTEMS - LOCALIZATION ANDPATTERN-FORMATION

Wave dynamics of open-sea ecosystems (''impact waves'') is considered in effect of nonhomogeneous hydrophysical fields. An influence of nonh omogeneity of various types on the possibility of impact wave stopping (localization) is elucidated. It is shown that lumped nonhomogeneity in certain parameters affecting population living conditions (such as salinity, water temperature etc.) may cause wave localization. Otherwi se, nonhomogeneity in the field of currents or in ocean turbulence lea ds only to some ware disturbances but not to stopping. It is shown als o that nonhomogeneity in ecosystem parameters may result in cell-like spatial distribution of a population.
