Using the method of numerical simulation, we found the nature of the postglacial transgression along the coasts of the Laptev and East Siberian seas to be affected by the shelf width and the continental slope depending on the viscosity properties of mantle layers. In particular, the marks exceeding the contemporary sea level, which are typical for the Holocene climatic optimum of 4–6 ka BP, may be located at different heights. Depending on the area, which fell under the increasing load of the incoming water due to the sea level rise during the postglacial period, and the viscosity of the mantle layers, the earth’s surface responds differently to changes in the load and restores its isostatic balance with different rates.
