| 701-0038-02L | Feldkurs Chemie und Umwelt  Maximale Teilnehmerzahl: 80 BSc Umweltnatuwissenschaften Studierende haben Vorrang bis 26.02.2018. Eine Warteliste wird bis 02.03.2018 geführt. Es darf nur ein Feldkurs pro Semester belegt werden. Entweder Feldkurs Ökologie (701-0038-01L) oder Feldkurs Chemie und Umwelt (701-0038-02L). | 1 KP | 2P | B. Wehrli | |
| Kurzbeschreibung | Der 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. | ||||
| Lernziel | Die 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. | ||||
| Inhalt | Einführung (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. | ||||

| Kurzbeschreibung | The 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. | ||||
| Lernziel | The 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) | ||||
| Inhalt | Each 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. | ||||
| Skript | Guidelines and supplementary material will be handed out at the beginning of the class. | ||||
| Literatur | Will be identified based on the chosen topic. | ||||
| Voraussetzungen / Besonderes | Each 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. | ||||
| 701-1504-00L | Winter School "Perspectives on daylight for the environment, health and architecture" Findet dieses Semester nicht statt. | 2 KP | 4G | B. Wehrli | |
| Kurzbeschreibung | The ETH Summer Schools provide young researchers with the opportunity to work on current and sustainability-related topics in interdisciplinary and intercultural teams. Focus is given not only to teaching theoretical knowledge but also to solving specific case studies. | ||||
| Lernziel | Within the ETH Zurich's new Critical Thinking Initiative (CTI), students are being guided to become critical and independently thinking individuals. During the course of their studies, they will acquire the following key skills and qualifications: the capability to analyse and reflect critically, to form an independent opinion and develop a point of view, as well as to communicate, argue and act in a responsible manner. Based on this concept, the ETH Sustainability Summer School is providing its students with the following qualifications and learning outcomes: - Improved scientific competence: Students gain basic knowledge in different scientific disciplines that goes beyond their selected study discipline. - Methodological competence: Students gain basic knowledge in different scientific methods that goes beyond of their selected study discipline. - Reflection competence: Students will learn how to work in interdisciplinary and intercultural teams to critically reflect their own way of thinking, their own research approaches, and how the academic world influences society. - Implementation skills: Students will apply creative technologies in solution finding processes to gain knowledge and prototyping-skills to increase hands on experience by applying knowledge in concrete cases. | ||||

Students will then, in small teams coached by the instructors 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 5 and the last 2 dates are reserved for lectures and seminars, during which presence of students is obligatory. | ||||
