Marine Biology

Marine biology is the study of marine organisms, their behaviours and interactions with the environment. The marine biology major provides a wealth of experiential learning opportunities for students with a combination of wet labs, field trips and project-based courses. Get out of the classroom and into the sea at our Bonne Bay Marine Station or conduct your own marine project (under the watchful eyes of our resident harp seals) at the Ocean Sciences Centre.


Marine Biology at Memorial

The joint major in Marine Biology is jointly administered by the Department of Ocean Sciences and the Department of Biology. It consists of core courses in oceanography and biology, and additional courses in various science subjects.

Each year we offer a number of exciting field courses at the Bonne Bay Marine Station, located in Gros Morne National Park on the west coast of the province. This world-class research and teaching facility is dedicated to marine ecology studies and has laboratories, boats, a resource centre, aquarium, multimedia theatre and residence accommodations.

Closer to St. John’s, with a dramatic view over Logy Bay, the Ocean Sciences Centre (OSC) is a state-of-the-art research and education facility located just 10 minutes from the main campus. The OSC has wet and analytical labs that support research on cold-ocean and deep-sea processes, aquaculture, biological oceanography, as well as marine ecology, physiology and biotechnology.

Note: Students interested in an honours or co-op in Marine Biology should contact the Department of Biology for further information.
