The pioneering marine biologist made it her calling to unravel the secrets of bioluminescence in world's deepest oceans. Bioluminescence is light produced by a chemical reaction within a living organism, and it’s more common in those dark depths than you may think.In this episode Edith talks about how she fell in love with the ocean at a young age, her short bout with blindness, which inspired her fascination with light and the moment she spotted a giant squid. This Episode of Talking Australia is hosted by Angela Heathcote (Senior Digital Producer at Australian Geographic) and produced by Ben Kanthak (www.beachshackpodcasts.com).
