For a detailed reconstruction of the atmospheric circulation during the last ice age in Europe, smaller ice caps and glaciers have to be considered. The aim of this project is a comprehensive reconstruction of the last glaciation of the Black Forest, according to the current, internationally accepted research approaches.The main research question of this project is:"When did the glaciation of the Black Forest reach its last maximum?"The answer to this question will have crucial implications for the atmospheric circulation during the Late Pleistocene. Establishing a chronology of glacier fluctuations using geochronological methods requires extensive labour, which is the core of this project. In addition, the already published findings on glaciations are summarised and supplemented by own work (remote sensing and field work). This will allow for a palaeoclimatic interpretation of the findings.The project is divided into four work packages:1) Review of the existing data and creating a representation of the glaciation using a LIDAR-based elevation model.2) Analysis of glacier characteristics by detailed geomorphological mapping of key areas and sedimentological studies of glacial deposits.3) Establishment of an independent chronology with terrestrial cosmogenic nuclides and OSL dating of rock surfaces and large clasts.4) Reconstruction of the ice geometry and dynamics of the last maximum extent and subsequent retreat stages using different approaches, including comparison with other palaeoclimate archives.

要详细重建欧洲最后一个冰河时期的大气环流，必须考虑较小的冰盖和冰川。该项目的目的是根据目前国际上公认的研究方法，对黑森林的最后一次冰期进行全面重建。该项目的主要研究问题是：“黑森林的冰川在什么时候达到最后一次最大值？”这个问题的答案将对晚更新世的大气环流产生至关重要的影响。使用地质年代学方法建立冰川波动年表需要大量的劳动，这是本项目的核心。此外，已经发表的关于冰川作用的研究结果由自己的工作（遥感和实地工作）加以总结和补充。这将允许对这些发现进行古气候解释。该项目分为四个工作包：1)审查现有数据并使用基于激光雷达的高程模型创建冰川的表示。2)通过重点区域详细地貌填图和冰川沉积物沉积学研究，分析冰川特征。3)建立独立的陆源宇宙核素年代学，并对岩石表面和大型碎屑进行OSL定年。4)利用不同方法重建最后最大范围和随后退缩阶段的冰的几何形状和动力学，包括与其他古气候档案的比较。
