Motivated to help improve the robustness of predictions of sea level rise, the BRITICE-CHRONO project advanced knowledge of the former British–Irish Ice Sheet, from 31 to 15 ka, so that it can be used as a data-rich environment to improve ice sheet modelling. The project comprised over 40 palaeoglaciologists, covering expertise in terrestrial and marine geology and geomorphology, geochronometric dating and the modelling of ice sheets and oceans. A systematic and directed campaign, organised across eight transects from the continental shelf edge to a short distance (10s of kilometres) onshore, was used to collect 914 samples which yielded 639 new ages, tripling the number of dated sites constraining the timing and rates of change of the collapsing ice sheet. This special issue synthesises these findings of ice advancing to the maximum extent and its subsequent retreat for each of the eight transects to produce definitive palaeogeographic reconstructions of ice margin positions across the marine to terrestrial transition. These results are used to understand the controls that drove or modulated ice sheet retreat. A further paper reports on how ice sheet modelling experiments and empirical data can be used in combination, and another probes the glaciological meaning of ice-rafted debris.

冰盖撤退的时间、速度和控制：英国-爱尔兰冰盖的 BRITICE-CHRONO 断面重建介绍

为了帮助提高海平面上升预测的稳健性，BRITICE-CHRONO 项目对前英国 - 爱尔兰冰盖（从 31 到 15 ka）的先进知识，使其可用作数据丰富的环境，以改善冰片材建模。该项目由 40 多名古冰川学家组成，涵盖陆地和海洋地质学和地貌学、地质年代测定法以及冰盖和海洋建模方面的专业知识。在从大陆架边缘到陆上短距离（10 公里）的八个横断面组织了一项系统和有针对性的活动，用于收集 914 个样本，产生 639 个新年龄，使限制时间和速率的过时地点数量增加了三倍。崩塌的冰盖的变化。本期特刊综合了八个断面中每一个的冰最大程度前进和随后的退缩的这些发现，以产生跨越海洋到陆地过渡的冰边缘位置的明确古地理重建。这些结果用于了解驱动或调节冰盖退缩的控制。另一篇论文报告了如何结合使用冰盖建模实验和经验数据，另一篇论文探讨了冰筏碎片的冰川学意义。
