Stretching over 30° of latitude, New Zealand’s coastline is more than 15,000km long, and its exclusive economic zone (EEZ) is one of the largest in the world. And yet our understanding of our own big blue backyard, and our impact on it, is extremely limited.

The physical and biological processes that power the Earth system unite in the ocean, determining Earth’s climate, supporting life and sparking our curiosity. Whether it’s finding new species, protecting sensitive habitats or solving our climate change problems, the University of Otago is uniquely placed to study these interlinked processes, and their effects on our lives.

Understanding our ocean planet is essential for meeting the challenges of our collective future.

Why study Marine Science?

The world is waking up to just how important the marine environment is to the survival of our planet. And when your office extends to the seashore and beyond, every day is a new challenge! A qualification in Marine Science from the University of Otago is internationally recognised, and its multidisciplinary nature opens up an ocean of opportunities.

I had the opportunity to study the impacts of climate change on benthic ecosystems, which involved regular scuba diving for fieldwork and close collaboration with internationally recognised researchers. This experience helped me develop essential skills that have set me up for a PhD in community and molecular ecology in France. The supportive environment and hands-on research made all the difference.
