Abstract

The study revealed the evidence for the marine waters penetration into the basin of Lake Kanozero (SW part of the Kola Peninsula) in the Late Glacial. While previous studies found no signal of marine transgression above ca. 41 m a.s.l., our results suggest that the local marine limit exceeded ca. 53 m a.s.l., and the sea ingressed as far inland as ca. 50 km from the present White Sea coast.
