Fundamentals of climate change
Antarctica is the engine room of the World’s climate, and harbours life that has adapted to extreme changes in the environment. Researchers at Otago University are working to understand how the Antarctic climate functions, the special adaptations of Antarctic species to their cold environment, and how the Antarctic ecosystem functions in terms energy flow and trophic complexity. Much of our research helps us to understand how the Antarctic will response to climate change processes.
Otago researchers collaborate at the national and international level with organisation including GNS, NIWA, ANDRILL, British Antarctic Survey, Alfred Wegner Polar Institute, AIMS, Scripps, GEOMAR as well as a number of New Zealand and overseas universities. Otago University also has facilities for returning Antarctic animals to New Zealand for off-ice research.

Researchers in Marine Science are involved in a range of Antarctica New Zealand research projects
Food web structure in Antarctica
Responses on Antarctic larval stages to environmental change (Ozone depletion and ultraviolet radiation, ocean acidification, sea temperature changes)
Response of Antarctic fish and larvae to hydrocarbon pollution.
Antarctic drilling programmes (ANDRILL) exploring past climates and responses of Antarctic Ice sheets climate change.
Physiological adaptations in Antarctic invertebrates.
The thermal biology of Antarctic invertebrates, and their responses to future increases in sea temperatures.
Changes in growth rates in Antarctic invertebrates over the past century.
Here on the doorstep to the Antarctic, you can carry out ground-breaking research into the global changes taking place in the world’s oceans.
Marine Science at Otago has an excellent record of collaborating with national and international organisations to undertake Antarctic research. Collaborators have been integrated into ongoing research programmes supported by Otago University and Antarctica New Zealand.
Students are critical to the success of Antarctic research programmes, participate in Antarctic research every year. As a student working in Antarctica, you will learn what you need to know in order to design your own research – and then carry it out. We have the resources, scholarships, staff and opportunities you need to reach your goals.
