The fast death of a lake

该研究项目涉及在石勒苏益格-荷尔斯泰因州（北德国）和邻近的可能晚冰期沙丘场，这可能是重新激活在年轻的全新世浅通道湖的年轻全新世的相互作用。由于不同的过程和人为干扰，湖泊从公元1800年前的100多公顷缩小到今天的不到5公顷。到目前为止，一个详细的方面和时间分类的萎缩过程和沙丘领域内的变化仍然缺乏。特别是，一个可能的沙丘复活的湖泊和现有的假定的天然或人工大坝的影响仍然是未知的。调查区域位于石勒苏益格-荷尔斯泰因州北部，沿着Treßsee湖，位于Upper Treene Landscape自然保护区内。与保护区行政部门密切合作。为了回答悬而未决的问题，在前湖盆和沙丘区进行钻探是必要的。沙丘砂、泥和有机残体应使用光释光、AMS和花粉测定年代。此外，沉积物和地貌应平衡，并使用地理信息系统和高清晰度数字景观模型进行建模。此外，应调查以前的污染物输入，特别是在集水区的香肠厂的油脂废水的后果。该项目的一个重要组成部分是学生参与实地和实验室工作。为此，设计了一个教学概念。此外，还计划在外地设立展示板。一位波兰科学家应该参与该项目。因此，适用旅费。事先有大量的准备工作，利用沙丘地区的景观模型和化石表面重建以前的湖泊水位。因此，我们能够在前湖盆中定义不同的过程区域，以重建湖泊干涸的各种过程。这些结果将作为计划项目的基础。

The research project deals with the Young Holocene interaction of a shallow channel lake in Schleswig-Holstein (North Germany) and an adjacent probably Late Glacial dune field, which was probably reactivated during Young Holocene. The lake shrank from more than 100 ha before 1800 AD to less than 5 ha today, due to different processes and artificial interference. So far, a detailed regard and a temporal classification of the shrinking process and the changes within the dune field are still missing. In particular, the influence of a probable dune reactivation to the lake and the existing of a presumed natural or artificial dam are still unknown. The investigation area is located in the North of Schleswig-Holstein along Lake Treßsee in the nature preserve area of Upper Treene Landscape. There is a close cooperation with the administration of the protection area. To answer open questions, drillings in the former lake basin and in the dune field are necessary. Dune sands, muds and organic relicts should be dated using OSL, AMS and pollen. Additionally, sediments and relief should be balanced and modelled using GIS and high definition digital landscape models. Furthermore, former pollutant inputs should be investigated, especially in consequence of the greasy wastewater of a sausage factory in the catchment. An important component of the project is the involvement of students in field and during laboratory work. For this purpose, a didactic concept was designed. Additionally, display boards in the field are planned. A Polish scientist should be involved in the project. Accordingly, travel expenses become applied. There were extensive prepares beforehand, dealing with the reconstruction of former lake levels using landscape models and fossil surfaces in the dune field. As a result, we were able to define different process regions in the former lake basin to reconstruct various processes of drying up of the lake. These results serve as a basis for the planned project.
