Gas Hydrates, Formation, Detection, Relevance

Lecturers: Ewa Burwicz-Galerne, Verena Heuer, Sabine Kasten, Thomas Pape, Miriam Römer, Florence Schubotz, Volkhard Spieß

Content:

Recent interest in gas hydrates emerges from the awareness that hydrate deposits may play significant roles in global and regional processes with societal and economic significance. A global hydrate assessment, although still uncertain, suggests that methane hydrates might represent an important future energy. In addition, other important hydrate questions that have attracted attention include: 1) Is there a feedback between methane hydrate stability and climate? 2) What is the role of methane hydrate in the carbon cycle? and 3) How much does gas hydrate contribute to seafloor stability on continental slopes? What is the future role of methane hydrate as major resource?

Competences:

After the successful completion of this lecture the students will have aquired a broad overview and understanding of gas hydrate systems in marine sediments, its interaction with the environment, and recent findings from ongoing research programs that illustrate key aspects of gas hydrate dynamics.


Assessment:

Written examination

Exam Form:

Klausur
