This paper considers the criteria for differentiating between stamukhas and grounded hummocks, and proposes a refined definition for the term “stamukha”. Sail height to keel depth ratio is a fundamental parameter of stamukhas. According to the data obtained in expeditions participated by the authors, this ratio for stamukhas is within the range of 0.6–1.8 for the Arctic shelf and of 0.4–1.5 for the Caspian Sea. The specifics of the study of stamukhas and complementarity of different research techniques are considered. Experiments based on the partial destruction of stamukha sail by thermal cutting of ice are proposed. The latter is used to prepare the conditions for ice-coring in hard-to-reach zones of stamukha, primarily from the consolidated layer, for textural and structural analysis.

Key words: ice ridge, stamukha, internal structure, consolidated layer, thermal drilling
