KurzbeschreibungDer Feldkurs besteht aus seiner Einführung und zwei Tagen Feldarbeit im Einzugsgebiet eines Sees. Die Studierenden erhalten einen Einblick in Messtechnologie für hydrologische und umweltchemische Fragestellungen. Sie lernen Datenreihen mit einfachen chemischen und dynamischen Modellen auszuwerten, und damit Fragen des Gewässermanagements zu beantworten.
LernzielDie Studierenden lernen in-situ Messtechnik, sowie Beprobung und Analyse von Wasser und Sediment kennen. Sie nutzen Ihr Grundwissen in Chemie und Systemanalyse zur Beantwortung von aktuellen Fragen zu Ökosystemfunktionen und zum Management eines Sees in einem intensiv genutzten Einzugsgebiet.
InhaltEinführung (3 h):
Übersicht zu den Kernthemen:
* Ein See als biogeochemisches Umweltsystem mit vielfältigen Umweltdienstleistungen; Vertikale Schichtung der Wassersäule, Variabilität der Zu- und Abflüsse; Sediment-Archive,
* Messsysteme zur räumlich- zeitlich aufgelösten Analyse von Seen und Flüssen,
* Arbeitsgruppen und Ablauf der Feldtage.

Der Feldkurs am Greifensee (2 Tage) behandelt vier Themen
1. Der See spiegelt das Einzugsgebiet: In kleinen Gruppen bestimmen wir die Stofffrachten der Zuflüsse und des Abflusses eines Sees. Flusswasserproben werden in einem Feldlabor analysiert
um daraus eine grobe Massenbilanz der Nährstoffe zu erstellen.

2. Sediment-Archive: Anhand von Sedimentkernen schätzen wir die Sedimentationsraten und rekonstruieren die Geschichte der Überdüngung.

3. Vom Licht in die Dunkelheit: Wir analysieren vertikale Profile in der Wassersäule mit verschiedenen profilierenden Sonden und behandeln damit folgende Fragen: Wie wirken sich Photosynthese und Respiration auf die Wasserqualität im See aus? Wie können wir mit chemisch-physikalischen Messungen auf die biologische Aktivität schliessen?

4. Denksport: Im vierten Teil verknüpfen wir die verschiedenen Fakten und destillieren daraus die wichtigsten Schlussfolgerungen.
SkriptSkript zum Feldteil und elektronsiche Datenreihen werden abgegeben.

KurzbeschreibungThe ability to critically evaluate original (scientific) literature and to summarize the information in
a succinct manner is an important skill for any student. This course aims to practice this ability, requiring each student to write a term paper on a topic of relevance for research in the areas of biogeochemistry and pollutant dynamics.
LernzielThe goal of the term paper is to train the student's ability to
critically evaluate a well-defined set of research subjects, and to
summarize the findings concisely in a paper of scientific quality. The
paper will be evaluated based on its ability to communicate an
understanding of a topic, and to identify key outstanding questions.
Results from this term paper will be presented to the fellow students and
involved faculty in the following semester (Term paper seminars)
InhaltEach student is expected to write a paper with a length of approximately 15 pages. The students can choose from a list of topics prepared by the supervisors, but the final topic will be determined based on a balance of choice and availability. The students will be guided and advised by their advisors throughout the term. The paper itself should contain the following elements: Motivation and context of the given topic (25%), Concise presentation of the state of the science (50%), Identification of open questions and perhaps outline of opportunities for research (25).
In addition, the accurate use of citations, attribution of ideas, and the judicious use of figures, tables, equations and references are critical components of a successful paper. Specialized knowledge is not expected, nor required, neither is new research.
SkriptGuidelines and supplementary material will be handed out at the beginning of the class.
LiteraturWill be identified based on the chosen topic.
Voraussetzungen / BesonderesEach term paper will be reviewed by one fellow student and one faculty. The submission of a written review is a condition for obtaining the credit points.
There is no final exam. Grade is assigned based on the quality of the term paper and the submission of another student's review.

KurzbeschreibungThis course focuses on the technical, economic, and political challenges of dealing with water allocation and pollution problems in large international river basins. It examines ways and means through which such challenges are addressed, and when and why international efforts in this respect succeed or fail.

This is a research seminar at the Master level. PhD students are also welcome.
LernzielThe students get an overview of (1) causes and consequences of water scarcity and water pollution problems in large international river basins; (2) they learn concepts to assess and mitigate such water challenges, and (3) they analyze when and why international efforts in this respect succeed or fail.
InhaltBased on lectures and discussion of scientific papers students acquire basic knowledge on contentious issues in managing international water resources, on the determinants of cooperation and conflict over international water issues, and on ways and means of mitigating conflict and promoting cooperation. Students will then, in teams of two and coached by Profs. Bernauer and Wehrli, do research on a case of their choice (i.e. an international river basin where riparian countries are trying to find solutions to water allocation and/or water quality problems). They will write a brief paper and present their findings during a final meeting at the end of the semester.
The first 4 and the last 2 dates are reserved for lectures and seminars. The students work on their case study from 22.03. to 17.05.
Skriptslides and papers will be distributed electronically
LiteraturThe UN World Water Development Report 2015 provides a broad overview of the topic
