GES 3170 - Critical Zone Science (3)


When Offered: Spring
Throughout this course, students will explore the processes, timescales, and biogeochemical cycles that drive the evolution and dynamics within the Critical Zone (CZ). The CZ extends from the groundwater and unweathered bedrock interface to the top of vegetation and evolves on both longer-term geologic and shorter-term human timescales. Skills developed throughout this course will help students understand how physical material and nutrients flow through landscapes. Topics include the interdisciplinary connections between geomorphology, soil science, biogeochemistry, hydrology, and living organisms (including humans); indoor and outdoor laboratories allow students to gain hands-on experience in measuring and interpreting CZ data. 

Lecture two hours, laboratory three hours.
Prerequisite: GES 2750
