Advanced treatment of marine biogeochemistry and global environmental change. The oceans play a predominant role in global environmental change particularly with respect to their major geochemical cycles of carbon, nitrogen, oxygen, phosphorus, sulfur, etc. The major features of these cycles as they operate on a global basis are presented. Examples of natural and anthropogenic perturbations at present and in the past are a major focus of this course. A significant segment of the material deals directly with the role of oceans in controlling atmospheric carbon dioxide through its biological and solubility pumps.
