Development of shelf ecosystems in conditions of glacioeustatic fluctuations of the ocean level

As a result of sea level change the largest changes are observed in coastal ecosystems. One possible reason of the currently observed changes of the Black sea level are glacioeustatic fluctuations in Global sea level. In the paper the differential equation describing changes in the relief of the shelf during the glacio-eustatic oscillations of the World Ocean level was proposed for the first time. The relationship between the inclinations of the existing and emerging shelf, abrasion rates and sea level changes is the basis of this equation. Examples of numerical and analytical solutions of the equation describing the shelf profile after the transgressive stage are given.
