| Inhalt | Each student presents the results of their term paper to fellow students and advisors and responds to questions and comments from the audience. | ||||||||||||||||||||||||||
| Skript | Guidelines and supplementary material are distributed on the Moodle platform. | ||||||||||||||||||||||||||
| Voraussetzungen / Besonderes | There is no final exam. Grade is assigned based on the quality of the presentation and ensuing discussion. To obtain the credits, it is mandatory to attend at least 60% of all seminar dates offered in the fall and spring semester. Active participation in discussion and feedback rounds is expected. | ||||||||||||||||||||||||||

| 701-1303-00L | Term Paper 1: Writing Only for Environmental Sciences MSc and Science, Technology and Policy MSc. | 5 KP | 6A | L. Winkel, M. Ackermann, N. Casacuberta Arola, K. Deiner, N. Gruber, J. Hering, R. Kipfer, R. Kretzschmar, K. McNeill, D. Mitrano, A. N'Guyen van Chinh, M. Sander, M. H. Schroth, C. Schubert | |||||||||||||||||||||||
| Kurzbeschreibung | The ability to critically evaluate original (scientific) literature and to summarise 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 of scientific quality 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 scientific literature and to summarise the findings concisely in a paper addressing a research question. At the end of the course, students will be able to: - narrow down a research question. - identify relevant literature to address the research question. - concisely summarise and critically evaluate their findings. - formulate key outstanding questions. | ||||||||||||||||||||||||||
| Inhalt | Each student is expected to write a paper with a length of approximately 15-20 pages. The students can choose from a list of topics prepared by the tutors, but the final topic will be determined based on a balance of choice and availability. The students will be guided and advised by their tutors throughout the term. The paper itself should contain the following elements: - Motivation and context of the given topic (25%) - Concise presentation and critical evaluation of the state of the science (50%) - Identification of open questions and perhaps opportunities for further 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. Specialised knowledge is not expected, nor required; neither is new research. | ||||||||||||||||||||||||||
| Skript | Guidelines and supplementary material are distributed on the Moodle platform. | ||||||||||||||||||||||||||
| Literatur | Original scientific literature will be identified based on the chosen topic. | ||||||||||||||||||||||||||
| Voraussetzungen / Besonderes | Please enrol latest until the first week of the semester. Contact termpaper(at)env.ethz.ch if you don't yet have access to MyStudies. The term paper course is primarily aimed at master students majoring in biogeochemistry & pollutant dynamics and ISTP students with a solid background in natural sciences and a strong interest in biogeochemistry & pollutant dynamics. Each student submits a term paper that will be reviewed by one fellow student and one faculty. The submission of the term paper and a written review of another student's term paper are a condition for obtaining the credit points. There is no final exam. The grade is assigned based on the quality of the term paper and the submitted review as well as on the presentation in the following term. Results from the term paper will be presented to fellow students and involved faculty in the following semester ("Term Paper 2: Seminar"). | ||||||||||||||||||||||||||

| 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 | ||||||||||||||||||||||||||

| 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. | ||||||||||||||||||||||||||
