NEW MORPHOMETRICAL DATA OF LAKE-LADOGA

Depth distribution in Lake Ladoga reflects the geological structure of the lake basin. Bottom relief determines the distribution of bottom s ediments, benthic organisms, horizontal temperature distribution and o ther characteristics and effects general current pattern in different seasons of the year. In this paper new values of mean depth, volume an d area of Lake Ladoga and its parts are presented, and also the length and fractal dimension of the shoreline are determined. Based on the a nalysis of relative volume curves, the integrity of morphogenesis of t he northern and the southern parts of Lake Ladoga despite their quite different bottom topography was established.
