EARS 34 Earth’s Biogeochemical Cycles

This course is a survey of biogeochemical interactions among Earth’s crust, oceans, and atmosphere, including perturbations due to human activities. Particular attention is given to carbon, nitrogen, phosphorus, and sulfur biogeochemical cycles and the role of these cycles in applied environmental challenges including, for example, greenhouse warming of atmosphere from carbon dioxide and chlorofluorocarbons and the effects of inorganic and organic wastes in the marine and aqueous systems.




CHEM 5 or 10 (may be taken concurrently) and one course from EARS 1-9 exclusive of EARS 7.

Distributive and/or World Culture


The Timetable of Class Meetings contains the most up-to-date information about a course. It includes not only the meeting time and instructor, but also its official distributive and/or world culture designation. This information supersedes any information you may see elsewhere, to include what may appear in this ORC/Catalog or on a department/program website. Note that course attributes may change term to term therefore those in effect are those (only) during the term in which you enroll in the course.
