The course will provide a broad background on the functioning of biogeochemical cycles with a special focus on marine environment. Students will learn about processes exchanging energy and elements among the atmosphere, hydrosphere, biosphere and geosphere. The main biogeochemical cycles that will be studied are: carbon, nitrogen, phosphorus, silicon, sulfur and iron. Special focus will be given to the biogeochemistry of the ocean on a biological timescale. An overview of main anthropogenic perturbations and impacts on biogeochemical cycles will be provided.

The program of the course is largely interdisciplinary combining together physical, chemical and biological oceanography. It will be adapted to be followed by students with a heterogeneous different backgrund.
