Why Bottomless Holes Exist In The Middle Of The Ocean
If you happen to be floating in shallow Caribbean water, ten feet above a turquoise lagoon floor, you'd feel completely safe. The reef glows around you. Fish glint in the sun. Everything is fine. Then you look down. And six feet from your fins, the seafloor just... opens. A perfect circle of pitch-black water, cut into the sand like a wound — a blue hole. And the deepest one ever found still hasn't reported its bottom to a single instrument. This is the story of how the Ice Age drilled bottomless shafts into the seafloor, the divers who never came back up, the poison layer that preserves everything it kills, and Taam Ja' — the Mexican blue hole that swallowed 420 meters of cable and kept going. #drownedearth #deepsea #oceandocumentary #deepocean CHAPTERS ▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀ 00:00 The hole with no bottom 01:50 What a blue hole actually is 03:35 Dean's Blue Hole 05:10 The Great Blue Hole of Belize 07:00 Dahab — the Diver's Cemetery 08:40 Dragon Hole 09:25 The poison layer inside 10:20 Taam Ja' — 420 meters, no bottom 12:00 Why the ocean floor has holes 13:45 Where to go next
