José Trujillo:
Hello, I’m José Trujillo. I’m a PhD student at the Marine Science Department, looking at behavioural ecology in young sharks.
Studying at Otago gave me the opportunity to do research with sharks in French Polynesia at a level that I couldn’t have imagined before. I think it was the very supportive environment that made me feel that my ideas were important and that my project matters. That, to me, is the number one reason to choose Otago over other universities.
Dr Bridie Allan:
Hi, I’m Bridie Allan. I’m a lecturer here at the University of Otago in the Department of Marine Science.
I hear you’re thinking about taking Marine Science. Marine Science is a multidisciplinary area of research and study. Essentially, that means marine scientists work across a number of different disciplines to understand how the marine environment is working.
Why is Otago such a great place to study Marine Science? There are two key reasons.
The first is that we are incredibly well equipped to study the marine environment. We have the Southern Ocean on our doorstep, a world-class marine lab just 30 minutes from the city, and access to a range of different research vessels. We also have study sites on Stewart Island and in Fiordland.
Undergraduates at Otago can expect to take a range of papers, covering everything from the biology and behaviour of marine invertebrates to large charismatic megafauna such as whales. We have a strong focus on fisheries and aquaculture—two really important topics as human populations continue to grow. We also explore physical and biological oceanography, and we study marine ecosystems as a whole through marine ecology.
And I can guarantee you’ll get your hands wet on multiple occasions as you participate in labs at the Portobello Marine Lab and gain valuable research experience on board our research vessels.
Now, I mentioned two reasons. The second is our people.
Our lecturers are dedicated to giving you the best learning experience possible while also being leaders in their own research fields. We have biologists, ecologists, physical oceanographers, chemists, and geologists. I myself am a behavioural ecologist—I study the behaviour of animals in their environment and, importantly, how that behaviour will change under future environmental conditions.
Because of our diverse research expertise, we work in a range of different locations—from Antarctica, the Auckland Islands, New Zealand of course, the South Pacific, and the Great Barrier Reef, which is where I do my research. We study a vast range of organisms, from sea urchin larvae and kelp forests to tropical and temperate fishes like sharks, and of course, whales.
Now more than ever, we need to focus on the marine environment, which faces increasing threats from global warming, ocean acidification, and marine pollution. We want our students here at Otago to work with us towards a more sustainable marine future.
There’s an ocean of opportunities here at Otago studying Marine Science—join us here at Otago to study the marine environment.
How you will learn
Marine Science is a hands-on, field-intensive subject. Alongside lectures and tutorials, you’ll gain valuable experience through laboratory work and coastal or offshore field trips.
Otago offers exceptional facilities, including:
- A fully equipped teaching and research centre on the Dunedin campus
- The Portobello Marine Laboratory, situated on the Otago Peninsula
- Remote field stations on Stewart Island and in Doubtful Sound
- A dedicated fleet of research vessels, including the RV Polaris II
You’ll develop practical skills in scientific diving, data collection, marine technology, analysis, and science communication – giving you the tools to thrive in the field or in further study.
Recommended high school subjects for undergraduate study
To prepare for a degree in Marine Science, we recommend taking biology, chemistry, physics, and statistics or calculus in Years 12 and 13.

Further study opportunities
Whether you are looking to bridge your undergraduate studies to advanced knowledge or aiming to specialise in a specific field, Otago offers a range of graduate and postgraduate options to suit your aspirations.
One of the reasons I was drawn to Marine Science is the variety it offers. There are so many things you can do in a day, from working in the lab, going out on the boat, or diving. During my postgrad studies I enjoyed getting involved with local community initiatives – helping out with the East Otago Taiāpure pāua/habitat surveys, presenting my PhD work at Taiāpure research evenings, and helping with the Ngāi Tahu Undaria control programme.
