Coral reefs are some of the most diverse ecosystems in the world.  They’re very special places, covering less than one percent of the seafloor but home to nearly a quarter of all ocean species at some point in their life cycle. In this episode of Ocean Matters, physicist and oceanographer Helen Czerski explores the state of reefs in some of the most remote parts of our planet. She learns about the latest research techniques being used by scientists and how archives of old dead corals are helping in the fight to save the corals of our future – and why we need to act so urgently?
