第四纪高纬度边缘的演变在很大程度上是由冰盖的进退所决定的。我们对这些边缘和冰盖作用的理解主要来自于Weichselian晚期的极地北大西洋。这一地区已形成了概念模型的基础上，冰川边缘如何工作，并随着时间的推移，特别侧重于槽口扇，海底滑坡和通道系统的演变。在这里，通过审查目前的知识状态的边缘北欧海在第四纪期间，我们提供了一套新的模型，不同类型的冰川边缘及其存款。这是通过跟踪格陵兰岛，巴伦支海和斯堪的纳维亚冰盖在过去的2.58 Ma的增长和衰退，以及这些冰盖如何影响沉积沿着其边缘。重建的历史表明：（1）记录的完整性沿沿着每个冰盖边缘是高度可变的。2)气候恶化和采用10万年的周期性对每个冰盖及其相关边缘的沉积和演变产生了渐进的影响。这些重建和记录在世界各地的其他边缘，使我们能够确定一阶控制沉积物输送在冰盖尺度上，提出新的概念模型槽口扇和冰川边缘的发展。我们还能够显示大型海底滑坡的发生和冰盖的历史之间的关系如何在不同类型的边缘变化。
Quaternary evolution of high-latitude margins has, to a large degree been shaped by the advance and retreat of ice sheets. Our understanding of these margins and the role of ice sheets is predominantly derived from the polar North Atlantic during the Late Weichselian. This region has formed the basis for conceptual models of how glaciated margins work and evolve through time with particular focus on trough-mouth fans, submarine landslides and channel systems. Here, by reviewing the current state of knowledge of the margins of the Nordic Seas during the Quaternary we provide a new set of models for different types of glaciated margin and their deposits. This is achieved by tracking the growth and decay of the Greenland, Barents Sea and Scandinavian Ice Sheets over the last 2.58 Ma and how these ice sheets have influenced sedimentation along their margins. The reconstructed histories show 1) the completeness of records along each ice sheet margin is highly variable. 2) Climatic deterioration and the adoption of 100 kyr cyclicity has had progressive impacts on each ice sheet and the resulting sedimentation and evolution of its related margin. These reconstructions and records on other margins worldwide enable us to identify first order controls on sediment delivery at ice sheet scales, propose new conceptual models for trough-mouth fans and glaciated margin development. We are also able to show how the relationship between large submarine landslide occurrence and ice sheet histories changes on different types of margin.
