The Glow Below

Molly Webster interviews deep-sea explorer and oceanographer Edie Widder about bioluminescence in the deep ocean. Edie recounts her early experiences with bioluminescent creatures, her dives in a specialized suit, and the discovery of the "flashback phenomenon," where marine snow lights up in response to stimuli. They discuss the various uses of bioluminescence by marine animals, such as finding food, attracting mates, camouflage, and defense. Edie shares her insights into the importance of bioluminescence as an indicator of life and communication in the ocean, as well as her personal experiences and sense of awe during her deep-sea explorations. The episode concludes with a discussion of a mysterious bioluminescent event Molly experienced and the potential for commercial deep-sea expeditions.
