Thesis Title

Ocean Deoxygenation: A palaeo-modelling perspective


Pearse began his PhD at the Institute for Marine and Antarctic Studies (IMAS) in late 2014. His research explores the biogeochemical mechanisms that control oxygen changes across past climate transitions. In doing so, he aims to develop an ocean biogeochemical model that accurately simulates known oxygen fluctuations in the past. This model and the information it provides may then be used to predict how oxygen in the ocean will respond to future warming.

Before joining IMAS, Pearse completed his Bachelors at the University of Tasmania and received first class honours at Murdoch University in Western Australia for his research into the biological oceanography of the Leeuwin Current. In a slight change of direction to follow his passion, he decided to enter the field of climate science and biogeochemistry.

Outside of his studies, Pearse has been involved as a research diver for universities in Australia and Mexico, worked as a research assistant in Antarctica and sailed the Catalonian coast of Spain doing scientific community outreach as part of an international NGO.
