Coral reef habitats

Long-term monitoring of coral reefs at inshore islands in the Great Barrier Reef Marine Park

We closely monitor coral reefs around Great Barrier Reef islands to understand their condition. We assess the impacts of disturbances such as cyclones, floods, and coral bleaching, and help track the patterns of recovery following these events.

Featured project

Coral reef habitats support thousands of species. The Great Barrier Reef alone makes up about 10 per cent of the world's coral reef ecosystem.

Our scientists undertake multiple monitoring programs to provide governments and industries with essential data on the condition of coral habitats. We also work closely with Traditional Owners, communities, and tourism operators in monitoring and coral reef resilience-building projects.

We surveyed over 250 km of coastline with First Nations partners to assess the impact of flooding caused by Tropical Cyclone Jasper, one year after the flood event.

Severine Choukroun

Research Associate

Severine Choukroun is a physical oceanographer and biophysical modeller with a background in marine science. Severine has developped hydrodynamic models models for understanding and predicting ecological processes – like how marine life moves in ocean currents – and understanding how physical and biological processes influence marine population connectivity and persistence. She has significant experience in conducting observational and modelling research on coastal and shelf dynamics, coupled with biophysical modelling that integrates complex early life behaviour. Severine’s recent activities include work with crown-of-thorns starfish (COTS), including a project with CSIRO to develop information infrastructure to better share modelled data between stakeholders involved in COTS control. This will improve data-sharing reliability and efficiency, while aligning with the broader infrastructures already being created through other programs. Severine is also studying patterns of COTS outbreaks on the Great Barrier Reef by tracking larval spread via ocean currents. Understanding, measuring and predicting how larvae are dispersed is vital to both modelling COTS outbreaks on the GBR and controlling those outbreaks effectively.
