SDG 14: Life Below Water

Ocean research at Dalhousie currently spans almost all faculties and disciplines. It all started with the establishment of the Institute of Oceanography in 1959, which launched a broader trajectory linking biological, physical, geological and chemical areas of ocean science, in the 1970s a marine law group was established. Now Dal hosts key ocean research facilities and is involved in many international research projects, which allow Dalhousie researchers to contribute to the most pressing ocean challenges of our time.

Learn how the ocean connects people across the world

Steps away from the Atlantic Ocean, Dalhousie has a global reputation for excellence in ocean education and research. When you study ocean sciences at Dalhousie, you’ll combine knowledge in the biological, chemical, geological and physical processes that make up ocean ecosystems.

The sea's the limit

If you’re passionate about the ocean, Dalhousie is where you want to be. We’re a national leader in marine biology education and research. You’ll learn in the classroom, lab and out in the field. You could find yourself on the water studying the behaviour of sperm whales, running your own underwater experiments, examining the diet of grey seals or assessing the diversity of marine birds.

MMM alumni are currently working in 52 countries

The Marine Affairs Program offers the Master of Marine Management degree to students with a strong academic record who are planning a career path in marine affairs and have an interest in climate change, public and private sector management, conservation science, planning, public service, engineering, community organizing or public policy.

Oceanographers study every aspect of the world’s oceans

The master's and a doctoral programs in oceanography give students the opportunity to collaborate with leading experts, to conduct fieldwork around the globe, to experience research at sea, and to participate in basic and advanced classes in all the sub-disciplines of oceanography.

Atlantic salmon seek solace in cooling zones created by Dal engineers

To alleviate the rigours of the trek back to their birthplace, wild Atlantic salmon often take breaks in chilly nooks known as 'thermal refuges.' These cooling stations, however, are dwindling because of the rising water temperatures and human-induced climate change. That prompted researchers in Civil and Resource Engineering, to see if humans could create thermal refuges for the endangered species.
