Global Biogeochemical Cycles explores the physical, chemical, biological, and geological processes that govern the composition of, and changes to, Earth’s surface environment. This course will focus on the global cycles of carbon, nitrogen, phosphorous, and sulfur and their interactions with organisms and earth materials as they move through the atmosphere, hydrosphere, biosphere, and lithosphere. This multidisciplinary course is intended for students curious about life’s influence on the planetary system. It will cover aspects of biology, geology, hydrology, meteorology, oceanography, and soil science. That said, no specific disciplinary background is required other than a fundamental understanding of elemental chemistry.
