Ocean Space: Marine Biogeochemical Processes

This course covers descriptions of the known biogeochemical processes and scientific challenges at the interfaces of seawater, landmasses, sediment and atmosphere. It will cover synthesis and extension of the information provided in marine chemistry, geochemistry, physical oceanography and biology. The course will also deal with the theory of various field techniques including sample collection, and some crucial instrumental methods for seawater analysis. More specifically course will cover the following topics: - Chemical composition of seawater, major and minor components, elemental speciation, ionic interactions in seawater. - Oceans' role in the global biogeochemical cycling of the selected elements. - Biogeochemical cycles of macro and micro nutrients. - Trace elements and their isotopes as tracers for physical, biological and geological processes. - Physical Oceanography, coupling climate and ocean currents and biogeochemistry. - Trace elements toxicity for marine bioata. - Photochemical processes in seawater, interactions between metal and organic matter. - Sediments, sediment-water interface, their role on the oceanic cycle. - Equilibrium and kinetic perspectives of marine processes. - Coastal systems and geochemical processes (Fjords, estuarine and shallow near-shore waters). In addition, selected HOT topics: - Climate changes and feedbacks from the marine biogeochemical cycles. - Ocean acidification and Carbon cycle. - De-oxygenation of ocean, suboxic, anoxic-sulfidic zones. - Limiting and controlling elements for the biological production: interactions between biogeochemical cycles and marine ecosystems.

After finishing the course, the candidates will:

• have knowledge about the known marine biogeochemical processes and scientific challenges at the interfaces of seawater, landmasses, sediment and atmosphere
• integrated and thorough knowledge of the chemical processes in the marine environment provided in marine chemistry, geochemistry, physical oceanography and biology
• have learned the theory of various field techniques including sample and data collection, and some crucial instrumental methods for seawater analysis

The students shall acquire abilities to:

• apply acquired knowledge within marine biogeochemistry to understand and predict how chemical, geochemical and physical processes affect marine organisms and ecosystems or vise versa
• critically present and discuss the content in scientific topics.
• communicate with colleagues in adjacent disciplines.
• work as a group member on a specific scientific topic They will be able to use this knowledge in environmental research, monitoring and management activities.

Lectures and seminars.

Schedule will be given at the start of the semester.

Expected work load in the course is 200-225 hours.
