Enjoy the Shorewords! podcast with Dr. Edith (Eddie) WIdder, author of Below the Edge of Darkness, marine biologist, and co-founder of Ocean Research & Conservation Association (ORCA, www.teamorca.org).  Eddie has spent years studying bioluminescence, which is light produced by living organism, and since most bioluminescent organisms are in the ocean, she has spent hundreds of hours in submersibles hoping to see flashes of light. Her podcast covers stories of her time under water and provides clear explanations of the current science on the hows and whys so many mid- and deep-ocean creatures blink and glow.
