KJM3070 – Biogeochemistry
The Earth's environment is tightly linked to the global cycles of carbon and other key elements like nitrogen, phosphorus and iron. These elements affect the climate system, biological production, diversity and ecosystem services, and the chemical composition of the environment. The course will focus on links between biological, geological and chemical processes, on the interactions between climate and the environment, and on how human activities affect these processes. Many of the UN's sustainability goals are closely linked to changes in ecosystem services, which is the overarching topic of the course. The main focus of the course is on terrestrial systems, including soil, vegetation and fresh water, and interactions with the atmosphere.
After completing the course, you will:
- Have knowledge on the Earth's development and the most important biogeochemical reactions in air and on land.
- Have knowledge about the biogeochemical cycles of carbon, nitrogen, phosphorus and sulfur.
- Be able to explain which biogeochemical processes govern these global cycles.
- Be able to explain how these cycles are interconnected.
- Be able to explain why and how the biogeochemical system is changing, as well as understand the uncertainties associated with such changes.
- Be able to explain how the climate affects and is affected by key biogeochemical processes.
- Have insights into the analysis of air samples, be able to use of air sample data.
- Have basic skills in the use of computer programs for biogeochemical modeling of soil and water systems.
- Be able to perform simple mass balance calculations.
Admission to the course
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.
The courses KJM3070 – Biogeochemistry and KJM4070 have joint admission. Students are ranked by the following criteria:
1. Bachelor ́s program students at the Department of Chemistry and master ́s program students at the MN Faculty who have the course approved in their study plan.
2. Other program students.
3. Single course students and exchange students.
Special admission requirements
In addition to fulfilling the Higher Education Entrance Qualification, applicants have to meet the following special admission requirements:
- Mathematics R1 (or Mathematics S1 and S2) + R2
And in addition one of these:
- Physics (1+2)
- Chemistry (1+2)
- Biology (1+2)
- Information technology (1+2)
- Geosciences (1+2)
- Technology and theories of research (1+2)
The special admission requirements may also be covered by equivalent studies from Norwegian upper secondary school or by other equivalent studies (in Norwegian).
Formal prerequisite knowledge
The following course must be passed before the first field work:
The following courses must be passed before the first laboratory exercise:
Recommended previous knowledge
Basic knowledge in biology and ecology.
- 10 credits overlap with KJM4070 – Biogeochemistry.
- 10 credits overlap with BIOS3070 – Biogeochemistry.
- 10 credits overlap with BIOS4070 – Biogeochemistry.
- 10 credits overlap with GEO3070 – Biogeochemistry.
The course duration is one semester. The teaching consists of:
- Mandatory environmental data workshop
- Mandatory lab / fieldwork / excursion
- Mandatory reports from practical modules
Lectures, computer labs and workshops in the course are held jointly for the courses: GEO3070 – Biogeochemistry, KJM3070 – Biogeochemistry, KJM4070 – Biogeochemistry, BIOS3070 – Biogeochemistry and BIOS4070 – Biogeochemistry.
All mandatory exercises must be approved before you can sit the final exam.
Approved mandatory activities are valid for 3 years.
You must be able to show documentation that you have passed the HSE courses on the first fieldwork/lab exercise.
It is mandatory to attend the first lecture (including students on the waiting list). If you are unable to attend the first lecture, you must notify the Department of Chemistry before the start of the lecture, otherwise your course registration will be cancelled.
Since the teaching involves laboratory and/or field work, you should consider taking out your own travel and personal injury insurance. Read about how you are insured as a student.
If mandatory activities have already been completed and approved, you are not entitled to repeat these activities. If you have been admitted to the course, but have not completed or received approval for the mandatory activities, you are entitled to participate in these activities if there is enough capacity.
- Final written exam counts 100 % towards the final grade.
This course has mandatory exercises that must be approved before you can sit the final exam.
It will also be counted as one of the three attempts to sit the exam for this course, if you sit the exam for one of the following courses: GEO3070 – Biogeochemistry, KJM4070 – Biogeochemistry, BIOS3070 – Biogeochemistry and BIOS4070 – Biogeochemistry
