We're all too aware of natural disasters that strike the land - but what about those that happen at sea?

In this episode we learn about how the Black Summer bushfires of 2019-2020 have left a lasting impact on coastal waters. We speak to Thay Barros from the University of New South Wales to find out more. Read about Thay's research here.

Also, a mystery solved. In 2016, more than 40 million mangroves over 1,000 km of coastline on the Gulf of Carpentaria died. Why did it happen, and what does it tell us about the future of mangroves? Neil Saintilan from Macquarie University has the answers. Read about his research.
