The Earth System Science Pathway (ESS) is an interdisciplinary field of study that examines the physical and chemical nature of the environment in various media (as well as atmosphere, rivers, lakes, oceans, soils, and lithosphere), their interaction with each other and with biological systems. ESS emphasizes the examination of human impacts on these complex environmental processes and the long term sustainability of living systems.

School of Interdisciplinary Arts and Sciences (IAS) Requirements & Policies
Interdisciplinary Practice & Reflection (IPR)
Within the above-listed 80 credits, students must complete the IPR requirement.
Areas of Knowledge
25 credits must be completed in each Area of Knowledge. The Areas of Knowledge are: Visual, Literary and Performing Arts (VLPA), Individuals and Societies (I&S), and Natural World (NW).
Multiply-designated courses may not be double-counted as fulfilling two Areas of Knowledge. Courses may apply to both an Area of Knowledge requirement and an ESS major requirement.
Upper Division Credit Policy
Of the credits applying to ESS major requirements, a minimum of 48 must be completed at the Upper Division (300-400) level.
Courses taken to satisfy ESS major requirements must be completed in matriculated status.
Admitted prior to Autumn Quarter, 2016?
Students admitted to the ESS major prior to Autumn 2016 may be eligible to complete an older set of major requirements. For more information, please check Requirement Changes Autumn 2016 page.
In addition to the general admission requirements, students must have completed the prerequisites to be considered for admission to the ESS major.
