Course Objective

This course focuses on the ocean's role in global biogeochemical cycling of selected elements. The impact of humans on the transport of elements within these cycles is given special emphasis. It includes a description of the chemical composition of seawater from the dual perspectives of elemental speciation and the impact of solutes on the physical behaviour of water. The role of the sediments in determining the chemical composition of seawater is discussed from both equilibrium and kinetic perspectives. The origin of petroleum and mechanisms of radioactive decay are given in this course.

Learning Outcomes of the Course Unit

1   1) will be able to understand biogeochemical controls in the ocean and be able to quantify their impact on marine systems
2   2) will be able to make predictions regarding the fate of material in the marine environment
3   3) will be able to outline the major fluxes of C, N and P in terrestrial and aquatic ecosystems
4   4) will be able to describe the major biological and biogeochemical processes that drive nutrient cycles

Planned Learning Activities and Teaching Methods

The course is taught in a lecture, class presentation and discussion format. All class members are expected to attend both the lecture and take part in the discussion sessions. Besides the taught lecture, group presentations are to be prepared by the groups assigned for that week and presented to open a discussion session.
