| 摘 要： | 冰岛位于北大西洋北部地区,是对全球气候变化最为敏感的区域之一,对其周边海域古海洋环境的深入研究是全球气候变化研究的重要组成部分。海冰的大面积分布是该地区的显著特点之一,对全球气候系统产生较大的影响意义。此外,冰岛周边海域大量火山灰沉积,也为古海洋环境研究提供了可靠的年代资料。本文以冰岛为中心,回顾了冰岛周边海域末次冰消期以来古海洋环境及海冰研究的现状,探讨了该海域不同记录之间的差异,并通过分析末次冰消期以来古环境研究的不足,提出了相应的展望。

| Abstract: | Iceland is one of the most sensitive areas to the global climate changes due to the location in the North Atlantic storm-track path and at the present-day boundary between Polar and Atlantic surface-water masses. Even relatively minor changes in the circulation pattern are likely to be archived in the sedimentary record in this sensitive boundary region. Therefore, further research on the paleoceanography of its adjacent seas is an important component in the study of global climate change. Extensiveness of the sea ice is one of the prominent characters in the area around the Iceland, which plays a significant role in the global climate system. Furthermore, the adjacent seas around the Iceland have widespread tephra layers, which provide dependable chronological data for the study of paleoceanography. In this paper, we firstly reviewed the current studies of paleoenvironment and sea ice changes in the adjacent seas around the Iceland since the last deglaciation, and then discussed the advantages and disadvantages of different paleoceanographic records which are based on diverse proxies in the study area. In addition, the deficiency of different paleoenvironment and sea ice proxies around the Iceland since the last deglaciation were also pointed out in this study. Finally, we prospected the future of paleoclimatic research in the regions around the Iceland in order to fill up the paucity of long-term paleoenvironmental records, like sea ice record. |
