701-0420-01LPractical Training in Biogeochemistry Information 7 credits14PL. Winkel, P. U. Lehmann Grunder, K. McNeill, M. H. Schroth, A. Voegelin, S. Winton
AbstractFirst, the students learn how to analyze soil systems with physical, chemical and microbiological methods. Later, the students train their experimental skills by conducting kinetic experiments in the laboratory and by quantifying process rates under field conditions in a river.
ObjectiveThe students learn to apply physical, chemical and microbiological analysis tools in the laboratroy and the field. They use their theoretical knowledge to interpret their own data, and to critically assess and document them.
Lecture notesDescriptions of the methodologies will be provided.
701-0423-00LChemistry of Aquatic Systems3 credits2GL. Winkel
AbstractThis course gives an introduction to chemical processes in aquatic systems and shows applications to various systems. The following topics are treated: acid-base reactions and carbonate system, solubility of solids and weathering, redox reactions, complexation of metals, reactions at the solid/water interface, applications to lakes, rivers and groundwater.
ObjectiveUnderstanding of chemical processes in aquatic systems. Quantitative application of chemical equilibria to processes in natural waters. Evaluation of analytical data from aquatic systems.
ContentIntroduction to the chemistry of aquatic systems. Regulation of the composition of natural waters by chemical, geochemical and biological processes. Quantitative application of chemical equilibria to processes in natural waters. The following topics are treated: acid-base reactions, carbonate system; solubility of solid phases and weathering; complexation of metals and metal cycling in natural waters; redox reactions; reactions at the interface solid phase-water; applications to lakes, rivers, groundwater.

AbstractThis class is the 2nd part of a series and participation is conditional on the successful completion of "Term Paper 1: Writing". The results from the term paper written during the previous term are presented to the other students and advisors and discussed with the audience.
ObjectiveThe goal of the term paper seminars is to train the student's ability to communicate (scientific) results to a wider audience and the ability to respond to questions and comments.
ContentEach student presents the results of their term paper to fellow students and advisors and responds to questions and comments from the audience.
Lecture notesGuidelines and supplementary material are distributed on the Moodle platform.
Prerequisites / NoticeThere 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.

AbstractThe 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.
ObjectiveThe 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.
ContentEach 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 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. Specialised knowledge is not expected, nor required; neither is new research.
Lecture notesGuidelines and supplementary material are distributed on the Moodle platform.
LiteratureOriginal scientific literature will be identified based on the chosen topic.
Prerequisites / NoticeThe 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 students 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. 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").
