KurzbeschreibungThis course links lakes, their subsurface and their environment. It will be discussed how lake sediments record past environmental changes (e.g. climate, human impact, natural hazards) and how lake sediments can be used to reconstruct these changes. Emphasis is also given on the modern limnologic processes essential in interpreting the fossil record. With 1 or 2-day field course on Lake Lucerne.
LernzielStudents are able to
- explain and discuss the role of lake sediments as archives of environmental change.
- plan an own limnogeologic campaign, i.e. finding, recovering, analyzing and interpreting the sedimentary lake archive to solve a particular scientific question.
- examine the complexity of a lake system with all its connection to the environment.
- relate subaerial processes with subaquatic processes.
- identify processes around and in lakes causing natural hazards.
InhaltContent of the course:
Introduction - Lakes, the small oceans
History of Limnogeology.
Limnogeologic campaigns
The water column: Aquatic physics (currents, waves, oscillations, etc.).
Sediments caught in the water: sediment traps
Geophysical survey methods (multibeam bathymetry, seismics)
Large open perialpine lakes.
Laminations in lake sediments: Clastic vs. biochemical varves.
Hydrologically closed lake systems
Chronostratigraphic dating of lake sediments
Lake sediments as proxies for climate change
Lake sediments as recorder of anthropogenic impact

The class includes a 1- or 2-day field practica on Lake Lucerne.
Introduction to themes of Lake Lucerne field course.
Limnogeological methods on the lake and in the laboratory: various sampling and surveying techniques (water analysis, seismic surveying, sediment coring, laboratory analyses).
Seismic-to-core correlation and interpretation
SkriptWill be distributed in each class unit.
