- Аннотация: The vertical isotopic profile of the ice core of a perennial frost heave mound—Messoyakha-1 bulgunniakh (pingo)—was obtained. The pingo is situated at 68°30′32″ N, 79°59′53″ E, in the southern part of the Gydan Peninsula within the Middle Messoyakha swell. No significant variations were registered in the isotopic composition of the mound ice core: δ18О varied from –14.98 to –16.60‰ and δ2Н varied from – 117.9 to –122.8 ‰. This small range of values probably resulted from intense heaving and rather rapid formation of the pingo. Based on the features of the pingo, it can be assumed that initially there was a lake of 0.5 km length and 0.3 km width at this site. Then, the water drained into a nearby river, the lake began to dry out, and the khasyrey (alas), which occupies most of the former lake area, was formed. The pingo itself arose during the freezing of the alas under its gradual drying out.
