本文介绍了2009年2月在柏林举行的一次研讨会的成果，该研讨会关注包括不列颠群岛在内的北方欧洲冰川史的当前研究。目前用于解决这个问题的方法进行了概述。特别注意的是新的分析方法，从高分辨率遥感成像的冰川地形在陆地和海床上，关键的新地层剖面，更高的分辨率结果，从传统的地质年代学方法，如放射性碳和最近开发的技术，如发光和宇宙成因放射性核素测年。从这两种方法得到的结果之间的关系进行了讨论，进一步详细沿着与可能的解释，这些差异。一个“最有可能”的斯堪的纳维亚半岛和英国和爱尔兰冰盖的冰川历史的轮廓，提出了沿着与全球气候变化的海洋同位素（MIS）记录所代表的可能联系。在MIS 22、16、12、10、8、6、4和2中确定了冰川作用的初步证据，并对斯堪的纳维亚、英国和爱尔兰冰盖的末次冰期内的“阶段”进行了探讨。结果表明，该地区不同地区的冰川作用的性质和程度是不同步的，需要更多的地质年代学工作，才能建立区域相关的信心。(C)2012爱思唯尔有限公司保留所有权利。
This paper presents the outcome of a workshop, held in Berlin in February 2009, concerned with current research on the glacial history of northern Europe, including the British Isles. The methodologies presently used to resolve this topic are outlined. Particular attention is given to new analytical methods deriving from high resolution remote imaging of glacial terrain both on land and on the sea-bed, key new stratigraphic sections, higher resolution results from conventional geochronological methods like radiocarbon and more recently developed technologies such as luminescence and cosmogenic radionuclide dating. The relationships between the results derived from these two methods are discussed in further detail along with possible explanations for these differences. An outline of a 'most likely' glacial history of the Scandinavian and British and Irish Ice Sheets is presented along with possible links to global climate change as represented by the marine isotope (MIS) record. Tentative evidence for glaciation is identified in MIS 22, 16, 12, 10, 8, 6, 4 and 2 and correlations of 'phases' within the Last Glaciation are also explored for both the Scandinavian and British and Irish Ice Sheets. The results show that the character and extent of glaciation in different parts of the region are not synchronous and much more geochronological work is required before regional correlations can be established with confidence.
