| 701-1333-00 P | Isotopes and Biomarkers in Biogeochemistry Laboratory
 Takes place in the 1st half of the semester. Sampling takes place at Lake Rotsee near Lucerne at the first day and is obligatory. Practical laboratory work takes place at EAWAG in Kastanienbaum (near Lucerne, 3 times), at Duebendorf (once) and we meet 2 times at ETH (room on appointment) for preparing the presentation and give the presentation.Detailed Information will be sent by mail shortly before the sampling campaign. | 4 Std. |

Katalogdaten
| Kurzbeschreibung | This 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. |
| Lernziel | Students 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 |
| Inhalt | Basics: 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 |
| Voraussetzungen / Besonderes | Sampling will take place in Rotsee (Lucerne). We will have 3 laboratory days at Eawag Kastanienbaum, 1 laboratory day at Eawag Duebendorf, and 2 days of preparation of a presentation and the presentation itself at ETH (Center). The presentation will be evaluated and is necessary to pass the class. |
