Semester of Instruction
Spring. Regular tasks during the semester in which the class is taught.
Place of Instruction
Objectives and ContentThis course centres on major global biogeochemical element cycles and their controlling processes. The course also covers major events in Earth¿s geobiological evolution, and how aspects of the history of life can be reconstructed by combining geochemical and fossil evidence. The goal is for students to understand the biological drivers and consequences of key transitions in Earth¿s history, for example the rise of oxygen, the «snowball» Earth, and the Cambrian explosion.
Learning OutcomesAfter completement of the course the student should be able to:
- give an overview of the earth´s main reservoirs of carbon, nitrogen, sulfur, iron and oxygen, and the geological and biological processes that control the fluxes between these reservoirs
- give an overview of the main microbial biomineralization processes and the most common biominerals in different environments
- describe the major classes of biosignature (microfossils, organic biomarkers, isotope records) and how these are used to reconstruct the Earth¿s geobiological history
- describe key processes and events in the co-evolution of Earth and life
Required Previous Knowledge
