Ocean Unpacked – Details, episodes & analysis

Episode Summary

In this episode, coral expert Dr Rhiannom Davies takes us into the fascinating world of corals - the ocean animals you probably didn’t even know were animals! From the fascinating way that corals grow and build entire reef ecosystems to the growing threat of climate tipping points, we explore why coral reefs are so important, how they might adapt in a rapidly warming ocean, and why the next few decades could be critical for the future of one of the planet’s most important animals.  

Our Guest

Dr Rhiannon Davies is a coral reef scientist from the University of Exeter studying how corals respond to environmental stress and climate change. Her PhD research focused on assessing the long-term condition and resilience of coral reefs in the Maldives, examining how reefs have responded to repeated mass bleaching events and what this means for coral recovery and restoration in a warming ocean.
