Dr Delphine Chabanne

Researcher, Murdoch University - Harry Butler Institute Centre for Sustainable Aquatic Ecosystems

Murdoch University marine biologist Dr Delphine Chabanne is a research Fellow at the Centre for Sustainable Aquatic Ecosystems at Murdoch’s Harry Butler Institute and has been studying Perth’s dolphins for more than a decade.

Delphine’s research interest broadly covers the field of population ecology, behaviour and genetics of coastal and estuarine cetacean species and has been involved in a number of coastal dolphins’ research programs across Australia, with a primary role in the long-term monitoring project of the dolphin population in Perth, Western Australia and the Dolphin Watch citizen science project.

Delphine completed her PhD thesis in July 2017 where she assessed the demographic, social and genetic structure of Indo-Pacific bottlenose dolphins inhabiting coastal and estuarine waters of Perth, Western Australia, including a special interest in the resident dolphin community in the Swan-Canning Estuary.

Delphine undertakes scientific vessel surveys of the Swan-Canning Estuary for the Department on a seasonal basis to help us monitor the individuals in this small sub-population. Delphine is also an amazing photographer and helps us put together Perth FinBook every two-years – an identification catalogue of dolphins in the Swan Canning Riverpark.
