Course content

The global environment is tightly linked to the global cycles of carbon and other key elements like nitrogen, phosphorus and iron. These elements are also closely related to the hydrological cycle as well as biological production, diversity and ecosystem services, and chemical properties of the environment. The course will focus on couplings between biological, geological and chemical processes, on the interactions between climate and the environment, and human impacts on these processes.

The lectures are common for the courses KJM3070 and KJM4070 while most of the colloquia, workshops and labs are being held separately.

Learning outcome

After completing the course, you will:

  • Have knowledge about the development of the biosphere on Earth and the major biogeochemical interactions in air, land and water. 
  • Have knowledge about the biogeochemical cycles of carbon, nitrogen, phosphorus, sulphur and mercury.
  • Be able to explain the major processes governing these cycles
  • Provide examples on how these cycles are linked
  • Be able to explain why and how the biogeochemical system is changing
  • Explain how climate and biogeochemical processes mutually interacts
  • Have obtained skills in calculation of chemical speciation by use of a speciation programme
  • Be able to perform simple mass balance calculations


Students who are admitted to study programmes at UiO must each semester register which courses and exams they wish to sign up for in Studentweb.

If you are not already enrolled as a student at UiO, please see our information about admission requirements and procedures.

Priority will be given to students in the bachelor program in Biosciences.
