摘要：

海冰的准确重建对反演气候和环境变化具有重要意义。近期研究表明, 有机指标高支链类异戊二烯(HBIs)具有重建极地海冰状况的潜质, 海洋沉积物中具有海冰特异性的单烯HBI(IP25)和双烯HBI(IPSO25)指标已分别成为研究北极和南极海冰变化的有力工具。本文综述了IP25、IPSO25的提出和验证, 分析了影响HBIs生成、迁移和埋藏的诸多因素, 总结了为实现精细化区分海冰状况和定量化重建海冰密集度而提出的新指标的发展及应用, 并就目前存在的问题和未来研究方向进行了探讨和展望。

Abstract:

Understanding long-term sea ice variations is crucial for reconstruction of past climate and prediction of future climate. Recently, highly branched isoprenoids (HBIs), which is an organic geochemical lipid biomarker, has been proposed as a possible indicator of polar sea ice conditions. Mono-HBI (IP25) and dine-HBI (IPSO25), which are produced by diatoms living in association with seasonal sea ice, have been considered as potential measures of Arctic and Antarctic sea ice, respectively. In this paper, we summarize the research on polar sea ice reconstruction using HBIs. These include verification of proxies, factors influencing effectiveness of proxies, and development and application of indices to categorize sea ice conditions and reconstruct sea ice concentration quantitatively. We also highlight research gaps and propose future research directions in this field.
