Biogeochemistry: An Analysis of Global Change by William H. Schlesinger, 2nd edition, Academic Press, 1997.
Occasional articles from the Web and handouts.
Recommended Reading (especially if ENVS 2 is ancient history for you)
Earth Under Siege: From Air Pollution to Global Change by Richard P. Turco, Oxford University Press, 1997. Everyone should read pages 1-9 and 289-291 after the first class. (on reserve in Kresge).
Description of Course
This course examines human influences on the major global biogeochemical cycles (water, carbon, nitrogen, sulfur, metals). We will emphasize cycling processes in terrestrial, marine, and--to a lesser extent--aquatic systems in an attempt to understand how human activities such as air pollution, deforestation, desertification and soil erosion alter these cycles. You may recall that Envs 2 is a survey course which covers a wide variety of topics at a moderate level of intensity. This course is designed to allow you to explore a few of those topics in greater detail.
There will be one in-class hour exam and a take-home final. The take-home exam might take up to two full days to complete. Two environmental problem set simulations will be assigned to give hands-on experience in understand the dynamics of change in biogeochemical systems. Each class member will prepare a 200-word abstract on a recent development in a topic we have discussed during the term. Two students will present their abstracts at the end of each class throughout the last four weeks of the term.

The Academic Honor Principle applies to all Dartmouth students at all times. I will speak about specific aspects of the Honor Principle as they relate to this class on the first day of the term.
