Excursion to Denmark, summer term 2022




+49 241 80 96064



As part of this year's large excursion, the Chair of Physical Geography and Geoecology offered the destination Denmark as a bus excursion with overnight stays in Bremervörde, Flensburg, Aarhus, Roskilde and Lübeck. The thematic focus was based on the different localities and several local experts involved in the planning of the excursion.

  • Supervision: Prof. Dr. Frank Lehmkuhl and M.Sc. Bruno Boemke
  • Destination: Denmark and Schleswig-Holstein
  • Period: 13.09. - 23.09.2022
  • Thematic focus:
    • Landscape evolution from the Late Pleistocene until today
    • Glacial geomorphology
    • Recent coastal processes and measures
    • Archaeology in the excursion area
    • German-Danish history in the borderland
    • Sustainable urban development

The stay in Schleswig-Holstein was thus structured according to the three major landscapes: Glacial morphological processes and forms of the Weichselian glaciation in the eastern hill country, Weichselian period outwash plains as well as Saale and Elster period ground moraines on the Geest and Holocene coastal processes on the tidal marsh. Through the geoarchaeological expertise of our local partner, Prof. Dr. Christian Stolz, the anthropogenic use and overprinting of these forms and deposits from the Stone Age to modern times played a central role. An example of this are the Weichselian dunes at Lake Treßsee, where repeated anthropogenic reactivation of aeolian activity since the Bronze Age could be shown on the basis of palaeo-soil sequences. To illustrate the economic relevance of the glacial outwash plains, there was also a guided tour of a site of the Heidelberger Sand und Kies GmbH by the chief operating engineer M.Sc. Christian Büchter. Due to the proximity to the German-Danish border, the topic of border history was repeatedly addressed during the stay in Flensburg and the trip to Aarhus, and important historical sites such as the battle of Dybbøl were visited.

In Aarhus, the focus was on glacial morphology and archaeology. On the first topic, the excursion group was guided through Central Jutland by our local partner, Prof. Dr. Jan Piotrowski. There were stops at Weichselian tunnel valleys, erosion processes on cliffs, megaripples formed by a glacial lake outburst flood (visible on the terrain model in Figure 2) and a glacial-tectonically shaped cliff, in which Miocene to Late Glacial deposits stand vertically. On the subject of archaeology, the Moesgaard Museum and the Centre for Experimental Archaeology, Sagnlandet Lejre, were visited. The multimedia and interactive design of the museum as well as the professional guided tour in Lejre gave the students an eventful insight into the archaeological history of Denmark from the Stone Age to the Viking Age.

In Roskilde, the focus was on sustainable urban development and the circular economy. For this, the cities of Copenhagen and Kalundborg were visited, where there were student-guided tours and presentations. In Copenhagen, the main topics were urban mobility and mixed use, while in Kalundborg the focus was on the circular economy under the banner "Kalundborg Symbiosis".
