Wintersemester 2022/2023

Zeit: Mittwochs von 14.00 - 16:00
Raum: Institut für Geowissenschaften, Burgweg 1, Seminarraum (3. OG) & Online
Dozent: Prof. Susan Trumbore

Teilmodul Biogeochemische Stoffkreisläufe (MUGM009, BBGW6.3.5)

Biogeochemische Prozesse in Erdsystem deren Einfluss auf die Kreisläufe von Energie, Wasser, Kohlenstoff, Sauerstoff, Stickstoff und Phosphor Zusammenhänge zwischen biogeochemischen Kreisläufen und Weltklima in der Erdgeschichte


  • Schriftliche Prufung/ written exam (72%) Übungen (excercises - Modeling cycles with R) (27%)
  • Lectures are held in English -- Prüfung, Discussion etc, in German or English (up to the student)
  • Class is held Wednesday 14:00-16:00 ; CLass will sometimes be taught in Zoom - in this cas a link will be sent to students who are registered for the course.
  • Each week will link to a page with links to lecture materials, notes, reading and questions
