Part 1: As a species we have always believed ourselves the most dominant on the planet, relentlessly expanding outwards to lay claim to the territories and natural resources we discover. And yet, over two thirds of the world remain beyond our reach, hidden deep beneath seemingly endless stretches of water. What do those depths hold for those in peril?

Part 2: This week, we continue our ongoing examination of nautical incidents which defy conventional explanation. In this second episode, we expand the boundaries of our investigation beyond the phenomenon of ghost ships. Join us, as we delve into yet more unexplained maritime occurrences. Tragic events which would send the crews of the vessels involved down to Davy Jones’ Locker.
