7. Scope of the course in credits

5 cr

8. Teacher coordinating the course

Ekaterina Ezhova

9. Course learning outcomes

The course covers the physics of the frozen ground, both seasonally freezing ground and permafrost.

Upon completing of the course, the student will

- describe the dynamics of periglacial environment associated with climate change; 

- recognize specific landforms due to freezing-thawing cycles and prerequisites for their formation;

- understand what defines the thickness of permafrost and position of its top and base;

- examine short-term seasonal dynamics of frozen ground as well as long-term processes manifesting on geological times;

- get acknowledged with modern views on practically important phenomena associated with permafrost, such as frost heave and ice segregation;

- apply the knowledge to analyze measured data sets.

The student will be able to understand and critically assess our current knowledge on the evolution of permafrost in a changing climate.


10. Course completion methods


The course consists of lectures and seminars where students prepare presentations based on scientific papers. Each student must do at least one presentation. In the second part of the course, there will be group work on data analysis of temperature measurements in the boreholes.



11. Prerequisites


Basic knowledge of thermodynamics and mechanics


12. Recommended optional studies

Geophysics of snow and ice

Basics of hydrology
