 My name is James Nestor. I'm the author of Deep Freediving Renegade Science and What the Ocean Tells Us About Ourselves. My talk is about oceanic senses, the six senses that are triggered both in the ocean and in the float tank. I focused specifically on magnetoreception, which is an animal's ability to home in on the Earth's magnetic field and use that for navigation. How a series of animals such as birds, sharks, turtles, even flies are able to use this ability in humans are too. And how this ability is actually very much activated in the float tank.
