Development of Solontsovskie Lakes as indicator of humidity within Central Sikhote-Alin in the Late Holocene

A detailed reconstruction of humidity changes in the Central Sikhote-Alin during the Late Holocene reveals that precipitation variations, rather than temperature shifts, primarily drove hydrological fluctuations. Using sediment analysis from Solontsovskie Lakes—particularly Nizhnee Lake—researchers identified rapid transitions between wet and dry phases, with frequent changes in diatom assemblages and peat-forming plants indicating unstable hydroclimatic conditions. While cooling periods generally coincided with decreased moisture, the Little Ice Age was notably wet due to increased precipitation. The study leveraged radiocarbon dating (with a temporal resolution of 30–60 years) and comparative analysis of two lakes to trace trophic shifts and organogenic sedimentation rates (up to 1.9 mm/year). These findings correlate local paleoclimatic events with global data, offering new insights into the region's climate sensitivity.
