This work presents some preliminary results of using oxygen isotopes ratio (?18O) for diagnostics of transient layer of upper permafrost of the coastal plains of Eastern Chukotka, NE Russia. Study methods included drilling of active layer and transition zone of permafrost and stable core isotope ratios analysis. The study revealed that ?18O values of ice from transient layer ranges from ?11.5? to ?14?. These values differ from those for massive ice beds and ice wedges in this region that allowed us to use stable i...
