701-0419-01LSeminar for Bachelor Students: Biogeochemistry3 credits2SD. I. Christl, A. N'Guyen van Chinh
AbstractCurrent research topics are presented and discussed based on scientific literature. The students prepare a presentation with the support of an expert. Subsequently, the topics are discussed jointly by students and experts in student-moderated discussion rounds. Presentation and moderation techniques are introduced and trained in the seminar, supported by instructions for constructive feedback.
ObjectiveThe seminar aims at introducing the students to current research in the field of biogeochemistry and connect them with researchers. After the seminar, students are able to …
- understand and critically evaluate original scientific papers and to communicate their findings in a coherent way (presentation); in doing so, they become familiar with different types of publications and relevant journals in the field of biogeochemistry;
- discuss scientific results, plan and lead discussion rounds (moderation);
- give and receive constructive feedback.
ContentPart 1: Literature search; presentation and moderation techniques.
Part 2: Literature study; online-exchange of information; presentation and discussion moderated by students.
Lecture notesSelected handouts will be distributed in class.
Prerequisites / NoticeDeadline for enrollment is the FIRST day of the semester. Later enrollment can only be accepted in exceptional cases and under certain conditions (e.g., restricted choice of topics and dates).
701-0533-00LSoil and Water Chemistry3 credits2GR. Kretzschmar, D. I. Christl, L. Winkel
AbstractThis course covers chemical and biogeochemical processes in soils and water and their influence on the behavior and cycling of nutrients and pollutants in terrestrial and aquatic systems. Approaches for quantitative modeling of the processes are introduced and applied in selected examples.
Objective1. Understanding of important chemical properties and processes of soils and water and their influence on the behavior (e.g., chemical speciation, bioavailability, mobility) of nutrients and pollutants.
2. Quantitative applications of chemical equilibria to processes in natural systems.
ContentChemical equilibria in aqueous solutions, gas equilibria, precipitation and dissolution of mineral phases, silicate weathering, weathering kinetics, formation of secondary minerals (clay minerals, oxides, sulfides), redox processes in natural systems, pH buffering and acidification, salinity and salinization, environmental behavior of selected essential and toxic trace elements.
