Do you want to learn more about the oceans, how they function today and how they functioned in the past? Then this course is for you. It is at advanced level and focuses initially on circulation patterns in the oceans, marine sedimentation processes and depositional environments, nutrient cycles, marine life habitats and ecosystems. Thereafter we study how the oceans developed over time scales of millions of years and how we can use marine sediments for studies of past climatic and environmental changes. The second half of the course has a regional focus and includes an expedition with a research vessel to the Swedish west coast or the Baltic Sea where we sample sediments that we then analyse in our laboratories. The results from the expedition are presented in a project report and the course is concluded with a written exam.
