Thermoterraces in syngenetic ice complexes are widespread along the erosion-dominated shores of the Yakutia Arctic coast. Thermoterraces progressively record quantitative information about their existence which may be used to determine the mean shore retreat rate during the time they are present. Initial measurements of four thermoterraces were carried out by the authors on the south coast of the Dmitry Laptev Strait in 2002, and shore retreat rates were calculated. Comparison of erosion rates obtained using thermoterrace dimensions and geodetic survey results with rates determined using aerial photographs showed that the erosion rate values obtained in these two ways are approximately of the same order.
