为了详细重建欧洲上一个冰河时期的大气环流,必须考虑较小的冰帽和冰川。该项目的目的是按照目前国际上公认的研究方法,对黑森林末次冰川进行全面重建。该项目的主要研究问题是:黑森林冰川何时达到最后一次冰川峰值?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代学需要大量的劳动,这是该项目的核心。此外,已经发表的关于冰川的研究成果通过自己的工作(遥感和实地工作)进行了总结和补充。该项目分为四个工作包:1)审查现有数据,并利用基于激光雷达的高程模型建立冰川模型图;2)通过对关键地区的详细地貌制图和冰川沉积物的沉积学研究,分析冰川特征;3)利用陆地宇宙成因核素建立独立的年表,并对岩石表面和大碎屑进行OSL测年。4)使用不同的方法重建上一次最大范围和随后退缩阶段的冰几何和动力学,包括与其他古气候档案的比较。
英文摘要
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.
