The paper considers the morphometric particularities of 129 first-year ice ridges studied in different regions of the Kara and Laptev Seas in the period 2007-2017. The dependence of the consolidated layer thickness of the ice ridges on the temperature conditions of the local region is shown, taking into account the average age of ice ridges in the region. Differences in the morphometry of ice ridges studied on landfast ice and drifting ice are considered. The morphometric characteristics of ice ridges in different regions are given, averaged over the gradations of the average consolidated layer thickness. A general pattern is shown that connects the consolidated layer thickness with the external parameters of the ice ridges.
