Abstract

Knowledge of the variation in sea-ice extent in the subpolar North Atlantic during the lateglacial and deglacial periods is still limited. According to the reconstructions by Müller & Stein (2014) there was a permanent sea-ice cover during the transition between the last glacial maximum and Heinrich event H1 (time interval 18,000–15,500 BP). However, Sarnthein et al . (1995, 2003), Weinelt et al . (1996), Nørgaard-Pedersen et al. (2003) and Zamelczyk et al . (2014) have shown that large parts of the Nordic Seas were ice free during the summers of the Last Glacial Maximum. During Heinrich Event H1 in the early deglaciation, the permanent sea-ice layer broke up with an export of sea ice and icebergs to the North Atlantic. Quaternary

在Fram海峡Vestnesa Ridge发现的晚第四纪陆源植物和煤屑:对斯瓦尔巴群岛冰川后植物殖民的启示

在冰川期和去冰期，对北大西洋亚极地海冰范围变化的认识仍然有限。根据m ller & Stein(2014)的重建，在末次盛冰期和海因里希事件H1(时间间隔为18,000-15,500 BP)之间的过渡期间存在永久性海冰覆盖。然而，Sarnthein等人。(1995,2003)， Weinelt等。(1996)， Nørgaard-Pedersen等人(2003)和Zamelczyk等人。(2014)的研究表明，在末次盛冰期的夏季，北欧海的大部分地区是无冰的。在早期冰消期的海因里希事件H1期间，永久海冰层破裂，海冰和冰山向北大西洋出口。第四纪

期刊介绍： A formal publication outlet for the International Palaeontological Association (IPA) and the International Commission on Stratigraphy (ICS), Lethaia publishes articles of international interest in the fields of palaeontology and stratigraphy. The articles concentrate on the development of new ideas and methods and descriptions of new features of wide significance rather than routine descriptions. Palaeobiology and ecostratigraphy are the core topics of the journal. In addition to articles, Lethaia contains shorter contributions in the form of discussions, presentations of current scientific activities, reviews and editorials. Lethaia was launched in 1968 as a joint venture between scientists in Denmark, Norway, and Sweden, with the aim of promoting the development of modern methods in scientific publishing and of providing a medium for rapid publication of well-prepared manuscripts of wide international interest.
