Abstract

The correlation between the isotopic composition of ice wedges and temperature of the cold period over the past 80 years in the north of the permafrost zone of Russia is verified using modern climate data. The meteorological observations from 1930 to 2017 and the values of δ18О in ice wedges for each region of the permafrost zone are analyzed to identify the most obvious and stable dependence of the isotopic composition and winter temperature. This will allow creating more detailed quantitative paleoreconstructions of climate change within the modern permafrost zone of Siberia.

俄罗斯北部多年冻土区近80年冰楔的同位素组成与冷季温度之间关系的验证

摘要

使用现代气候数据验证了俄罗斯多年冻土区北部过去80年的冰楔同位素组成与寒冷时期温度之间的相关性。分析了1930年至2017年的气象观测数据以及多年冻土区每个区域冰楔中的δ18О值，以确定同位素组成和冬季温度的最明显和最稳定的依赖性。这将允许在西伯利亚现代多年冻土带内建立更详细的气候变化定量古构造。
