Abstract. This work presents the results of field studies conducted on the shores of Lake Ladoga during the 2023 field season. The goal of the research is to determine the oscillations in the lake level following the maximum of the Ladoga transgression between 2800-3100 BP. For this purpose, coastal systems on the southern (Storozhensky Peninsula) and western (the Taipale Bay) shores of Lake Ladoga were studied. The comprehensive research included geomorphological profiling of coastal terraces, studying the geological structure of peat bogs and coastal relief forms, collecting samples for radiocarbon and OSL dating, as well as diatom analysis. As a result of the conducted studies, the heights of the shoreline at the maximum stage of the Ladoga transgression were determined for both sites, and a transgressive oscillation of the lake level during the late Holocene regression was identified. Keywords: Ladoga transgression, the Late Holocene, geomorphologic profiling, peat coring, OSL-dating, radiocarbon dating
