Marine Sciences

College of Science and Mathematics

Marine science is the study of the ocean, including the physics, chemistry, biology and geology, and how those features interact to create the amazing complexity of the sea. Understanding these processes is more important that ever as human impacts increasingly affect the oceans.

The bachelor's degree in marine sciences provides a broad foundation with introductory and upper division course work across a range of disciplines in marine sciences. Because the program is so interdisciplinary, the degree is flexible and allows you to tailor your studies to your specific interests. The program provides ample opportunities for you to engage in research under faculty guidance, including impactful independent capstone projects.

Marine Science Curriculum

In addition to lab work in the biological sciences and in chemistry, marine sciences offers labs specific to the major. Examples include:

  • Aquaculture
  • Fisheries Science and Resource Management
  • Ocean Sampling Techniques
  • Marine Botany
  • Marine Conservation and Policy
  • Marine Ecology
  • Marine Mammals, Birds and Reptiles


About the Program

Cal Poly Pier in Avila Beach from the air.

Situated minutes from the Pacific Ocean on California's Central Coast, Cal Poly has a private research pier, several research vessels, a flow-through seawater system and many other resources on-campus that make us an ideal location for training the next generation of marine scientists.

Through course-based lab work and faculty-led research projects, you will develop real-world knowledge in areas such as physiology of marine organisms, conservation, fisheries, oceanographic sampling, and data management and analysis. There are many opportunities to apply what you learn through faculty-mentored research projects in the lab and on the water.

Learn by Doing

In the midst of a rich and diverse marine ecosystem, our Center for Coastal Marine Sciences is the epicenter for hands-on field research. Our pier laboratory facility in nearby Avila Beach allows you to study a range of topics — from the ecology of kelp forest animals to the physics that drive ocean currents — in a true marine environment. This real-world experience allows you to become part of the process of creating new scientific knowledge.
