Catalogue data

AbstractThis course will illustrate how different tracers and isotopes are used in natural systems. Here especially the processes (transformation, timescales) that take place and can be revealed by tracers/isotopes will be demonstrated but also flux rates will be calculated using different tracers.
ObjectiveStudents know how to use tracers/isotopes to investigate/understand ecosystems
They will understand the methods and analytical devices related to tracer/isotope work
Have a feeling for timescales on which natural processes occur
Students will be able to apply different sampling techniques in aquatic sciences
ContentBasics:
O,H isotopes as tracers for mixing in aquatic systems
Carbon isotopes as tracer for methane oxidation
210Pb, 137Cs as a tracer for sedimentation rate/mixing
SF6, Neon, He as tracers for exchange processes at the air/water interface

Case assessment:
Sampling of a Swiss lake (Rotsee)
Sampling techniques for different elements
Sample preparation for different techniques
Measurements at isotope mass spectrometer/gamma counter
Interpretation of results from the special sampling campaign and in a broader context
