Changes to science masters’ degrees from 2027
From 2027, our science masters' degrees are changing. The Master of Science will be renamed to the Master of Science (Thesis).
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.
Are you just starting uni?
Learn about studying Marine Science as an undergraduate at Otago.
Choose a study option
Whether you are advancing your career with our specialised graduate qualifications or pursuing in-depth research and expertise through our postgraduate programmes, Otago is here to support your aspirations.
Postgraduate qualifications
Honours, masters’, PhDs, and other advanced degrees for graduates. Just one additional year of study will earn you a valuable postgraduate degree. Or perhaps you want the depth of a full year of research-only time during a master’s or to step up to a PhD.
Bachelor of Science with Honours (BSc(Hons))
A four-year degree focusing on advanced study and culminating in a research project in the final year
Postgraduate Diploma in Science (PGDipSci)
A one-year programme which builds on an undergraduate science degree, encompassing coursework and a chosen research topic
Master of Science (Thesis) (MSc(Thesis))
A two-year degree with a wide range of subject options. The MSc(Thesis) may be taken by a combination of coursework and thesis, or by thesis only.

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.
