Abstract. The results of a study of the isotopic composition of δ¹⁸O and δD of underground ice, tested by the authors during fieldwork in the lower reaches of the Indigirka River, are presented. in 2023. Field research was carried out in the area from Belaya Gora to Chokurdakh. Due to the poor exposure of the ice complex deposits, the main work had been carried out on two outcrops - Malykhchyn and Shamanovo. Shamanovo outcrop has been described by the authors for the first time.

Keywords: oxygen and hydrogen stable isotopes, ground ice, ice complex, paleoenvironment
