摘要
冰芯记录了自然和人类活动等各种因子的变化,是研究全球气候变化和环境变化的良好载体。极地冰芯可以将高分辨率古气候记录的时间尺度延长至过去几十万年,具有重要的科学意义。近年来,极地冰芯在气候及环境记录上取得了一系列新的研究进展,但尚缺乏系统的总结。本文对极地冰芯的研究进展进行了梳理,从冰芯物理特性、冰芯氢氧同位素、可溶及不可溶物质理化特征、冰芯气体等方面进行了概述,重点关注了最新分析方法在极地冰芯中的应用。最后对极地冰芯研究的未来发展方向进行了展望,以期为今后深入开展极地冰芯气候及环境记录研究提供参考。
Ice cores record past changes in precipitation,temperature,volcanic activity,and solar activity,and are therefore good proxies for studying global climate and environmental change.Polar ice cores play are unmatched in their capacity to extend the time scale of high-resolution paleoclimate records hundreds of thousands or even millions of years into the past.In recent years,a series of new research advances have been made in the study of polar ice cores,but there is still a lack of a systematic summary on this topic.In this paper,the latest research progress related to polar ice cores is reviewed.We mainly focus on polar ice cores’physical properties,stable water isotopes,soluble and insoluble substances,and trapped gases.Finally,possible future directions of polar ice core research that could provide important new insights are discussed.
