    Are you passionate about the oceans, fascinated by marine life and driven to protect our planet’s most precious resource? Are you ready to immerse yourself in a world of discovery, exploration and innovation? Gain the knowledge and skills to become a leader in Marine Science and be part of a community that is dedicated to safeguarding the future of our oceans.

    Why study Marine Science?

    New Zealand boasts a vast 15,000km coastline and one of the world’s largest exclusive economic zones (EEZ). Despite this, our knowledge of our marine environment remains limited. You have the opportunity to change this.

    Studying Marine Science is a hands-on experience. As well as attending lectures and tutorials, you’ll have practical labs and field trips at sea. Alongside our research and teaching facilities in Dunedin, we have a major research laboratory on the Otago Peninsula and field stations on Stewart Island and in Doubtful Sound. A fleet of research vessels, including the expedition vessel RV Polaris II, provides access to local marine habitats.

    The ocean is the epicentre of Earth’s physical and biological processes, influencing our climate and sustaining life. The University of Otago is in the perfect place to investigate these interconnected processes and their impacts on our world. And when your workspace extends to the seashore and beyond, every day presents fresh challenges.

    Career opportunities

    A Marine Science degree opens doors to diverse and impactful careers. Otago graduates work in research, conservation, government, education, and industry – both in New Zealand and around the world. Employers include NIWA, the Department of Conservation, MPI, local councils, consultancies, and NGOs. Potential careers include:

    • Marine biologist
    • Oceanographer
    • Environmental consultant
    • Fisheries scientist
    • Aquaculture specialist
    • Marine policy adviser
    • Research technician
    • Coastal resource manager

    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.

    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.
