Abstract
Theoretical aspects of the stability of marine ecosystems under the influence of the dynamics of hydrometeorological conditions are considered. Groups of natural factors of the ecosystems of the Baltic and White seas defining a level of stability – biocenotical, dynamic hydrological, the dynamic oceanological and corresponding to them estimated indicator indices with assessment of their information significance are justified. Rating of values of indicator indices is executed. Three versions of the integral index of assessment of stability of AISE (integrated assessment of sustainable existence) based on accounting of 6, 9 and 15 indicators indices are developed. On the basis of the received integral estimates zoning of ecosystems of the Baltic and White seas in relation to their stability is executed. Need of accounting of a level of stability of specific water areas in the course of planning and implementation of sea economic activity – navigation, dredging operations, mounting of underwater infrastructure, industrial fishing is justified.
