Development and validation of computational fluid dynamics models for the coupled simulation of heat transfer and fluid flow in the coral microenvironments
MetadataShow full item record
This thesis explored the temperature deviations between coral surface temperature and ambient seawater temperature that likely determines the microscale processes involved in coral bleaching. The work presented here applied Computational Fluid Dynamics (CFD) technique coupled with hydrodynamic modelling and ray-tracing to predict coral surface warming due to the effects of stressors. This thesis demonstrates that modelling microscale temperature could yield important insights into thermoregulation in corals, which may lead to a more effective reef management.

Limits to the thermal tolerance of corals adapted to a highly fluctuating, naturally extreme temperature environmentSchoepf, V.; Stat, Michael; Falter, J.; McCulloch, M. (2015)Naturally extreme temperature environments can provide important insights into the processes underlying coral thermal tolerance. We determined the bleaching resistance of Acropora aspera and Dipsastraea sp. from both ...
A change in coral extension rates and stable isotopes after El Niño-induced coral bleaching and regional stress events.Hetzinger, S.; Pfeiffer, M.; Dullo, W.; Zinke, Jens; Garbe-Schönberg, D. (2016)Coral reefs are biologically diverse ecosystems threatened with effective collapse under rapid climate change, in particular by recent increases in ocean temperatures. Coral bleaching has occurred during major El Niño ...
