9. Course learning outcomes

The course overall goal is to provide adequate knowledge on sea-ice geophysics which can be related to many important applications, such as winter navigation, weather and climate, so that participants will obtain skills to apply the sea-ice geophysics to solve problems associated with these applications.

After this course, the participants:

  1. Can describe the structure and forms of sea ice, and discuss about physical processes related to their formation.
  2. Explain the role of thermodynamics in the evolution of sea-ice cover, particularly the thermal growth and decay of ice. Related to this, apply analytical solutions to resolve problems related to sea-ice thermodynamics.
  3. Explain the role of dynamics in the evolution of sea-ice cover including motion, rheology and deformation. Related to this, apply analytical solutions to resolve problems related to sea-ice dynamics.
  4. Design and execute simulations with thermodynamic-dynamic sea-ice models and analyze their output.
  5. Discuss about the role of sea ice in the Earth's climate.
