Stable isotopes 18O and D in cave ice of the Lena Pillars National Nature Reserve (Eastern Siberia).

Researchers analyzing stable isotopes (18O and D) in cave ice within the Lena Pillars Nature Park revealed distinct isotopic signatures that reflect regional climatic conditions. The study identified three primary clusters of isotopic composition: continental, arctic, and mixed, suggesting complex moisture source dynamics influencing precipitation patterns. This finding provides new insights into paleoclimatic reconstructions for Eastern Siberia, where cave ice serves as a valuable archive of past environmental conditions. The research employed high-resolution isotopic analysis to distinguish between local and distant atmospheric influences, offering a novel approach to interpreting proxy data in periglacial environments.
