About the Program
The B.S. in Marine and Coastal Science (MACS) is a new cohort-based, interdisciplinary, and experiential program designed to provide students with the opportunity to engage in coastal and marine-focused research.
Active learning experiences help students develop into confident, thoughtful, ethical scientists who are ready to address the growing challenges affecting marine and coastal environments.
Each year, a new cohort of students begins the program, engaging in hands-on research and learning experiences in and around the Salish Sea, with opportunities for focused, residential study at Western’s Shannon Point Marine Center (SPMC) in Anacortes, about an hour from the main campus.
Program Features
Study Marine Science Across Disciplines
The new MACS major is a partnership between three existing academic departments (Biology, Geology, Chemistry, and Environmental Sciences) and Shannon Point Marine Center. You will have a unique opportunity to study marine science in an environment of interdisciplinary collaboration.

Learn, Work, And Thrive Together
Study marine science as a cohort, beginning with an early research experience upon program admissions, and continuing through the 3rd year with the core course series, and culminating with a capstone project in your final year.

Gain Research Experience
You will have opportunities to engage in mentored, hands-on research opportunities in your sophomore year through immersive study at the marine center in Anacortes, Washington.
Work At A Marine Lab And On Research Vessels
Spend time in the field, on oceanographic vessels, and in learning laboratories. Engage deeply in marine research and focused study of the Salish Sea.
