"Dangerous Waters" - Undersea Explorers Through The Millennia

Working Over Time

This episode takes us to some of the deepest, darkest and most awe-inspiring settings planet Earth has to offer. We’re doing a deep dive into, deep diving, as it happens. Specifically, the perilous quest to discover and map unexplored caves in our oceans’ harshest, most remote corners. Our guide is the intrepid Jill Heinerth, a renowned underwater explorer and cave mapper whose projects span decades, and whose insistence that discovery is the driving force of human advancement is an inspiration to us all. Jill’s taking us back to the earliest days of her profession - that’s all the way back to 350 BCE - when ancient divers employed astonishingly complex tools and techniques to explore the oceans whose surfaces were inscrutable, but whose depths yielded deep sea resources and the intangible rewards of piercing that watery veil, to behold an entirely different world. We’ll also examine how the modern profession of underwater exploration is transforming our understanding of what really lies beneath the water that covers over 70% of Earth’s surface, and how what’s -down there- relates to what’s happening -up here-, past, present, and future. So, strap on those “rebreathers” and join our plunge into the vast, uncharted seas. With Jill leading the way, it’s sure to be an adventure to remember.
