Bachelor of Science in Earth, Atmospheric & Planetary Sciences

The requirements for the major are designed to give you the chance to explore the research area that excites you. After building a foundation with the subjects in the Core, you will select Lab/Field subjects and restricted electives that support your interests. Your advisor will help you build a coherent program. Whichever subjects you might choose you will build quantitative and analytical skills that  will be important for your career after earning by degree.

Core Subjects

All majors complete these subjects.

12.001 Introduction to Geology
12.002 Introduction to Geophysics and Planetary Science
12.003 Introduction to Atmosphere, Ocean, and Climate Dynamics
12.009 Theoretical Environmental Analysis
18.03 or 18.034 Differential Equations
12.TIP & 12.ThU Senior Thesis

Lab/Field Subjects

You must take one of the following field or laboratory options. Choose the option that most closely relates to your interests. The course you select will also fulfill the requirement for one CI-M course, usually taken in the junior year.

12.115 & 12.116 Field Geology II and Field Geology Analysis
12.221 & 12.222 Field Geophysics and Field Geophysics Analysis
12.307 Weather and Climate Laboratory
12.335 Experimental Atmospheric Chemistry
12.410J Observational Techniques of Optical Astronomy 

Restricted Electives

You will choose 60 units from the Discipline or Supporting Science electives. The lists of electives are sufficiently broad so that you can customize a program to match your interests. No more than 36 units can be from Supporting Science. Students with appropriate interests may substitute two subjects in urban planning, economics, policy, or management for subjects in the Supporting Science category.



Because of the breadth of the disciplines included in EAPS, there are many options for assembling a coherent set of electives. Take a look at some roadmaps customized for various research areas, and then discuss your plans with your advisor.
