The Undergraduate Earth and Atmospheric Sciences Experience

As an undergraduate student in the Department of Earth and Atmospheric Sciences, you will spend time with faculty and graduate students in and outside of the classroom.

If you’re pursuing a Bachelor of Science degree, you will take fewer humanities core courses, instead focusing on developing sciences and mathematics skills. If you’re pursuing a Bachelor of Arts degree, you will take a variety of liberal arts courses to prepare you for careers related to your major.

  • Bachelor of Arts or Bachelor of Science in Environmental Science
    Saint Louis University's undergraduate major in environmental science will develop your understanding of Earth's natural systems and their interconnections with human society. The program is designed to help you thoroughly understand the geosphere, hydrosphere and biosphere before focusing on sub-disciplines such as human population growth or climate change.
  • Bachelor of Arts in Environmental Studies
    Environmental studies focuses on the relationship between the environment and social, economic, political, legal and human aspects of society. As global population and consumption rises, understanding the interplay between environmental and social systems has become an increasingly important component of decision-making and planning.
  • Bachelor of Arts or Bachelor of Science in Geology
    Students who major in geology at Saint Louis University study Earth’s physical structure and formation. You’ll decipher history from rock record, locate natural resources, identify hazards and understand our planet’s natural processes.
  • Bachelor of Science in Geophysics
    Geophysics uses physics, mathematics and chemistry to understand gravity, earthquakes and magnetism. Learn about the Earth through the exploration of seismic waves, as well as its magnetic and gravitational fields. You'll also examine natural phenomena such as earthquakes, floods and landslides, and learn about plate tectonics.
  • Bachelor of Arts or Bachelor of Science in Meteorology
    Meteorology is more than just the study of weather. Meteorology students at Saint Louis University apply principles of physics and chemistry to discover what makes our atmosphere work. You’ll use math to arrive at predictions and delve into the important issues of ozone depletion and global warming.

The Graduate Earth and Atmospheric Sciences Experience

Whether your interests lie in environmental science, geology, geophysics, geographic information science or meteorology, the Department of Earth and Atmospheric Science’s graduate program has an option for you.

You’ll work alongside professionals in the industry and closely with professors to gain hands-on experience relevant to your major. Research will guide your education, with the opportunity for funding from major external organizations like the National Oceanic and Atmospheric Administration and the National Aeronautics and Space Administration. Access to workstations with specialty software will aid your research and understanding of earth and atmospheric sciences.
