Dive Mission Into ‘The Great Blue Hole’ Uncovers Dark Secret Hiding In The Murky Depths

1. Quest To The Caribbean

Fabien Cousteau is a world-renowned deep-sea explorer with a passion for ocean conservation. From scoping out underwater Civil War shipwrecks to swimming with and documenting sharks up close and personal on multiple occasions, he’s done it all. One recent mission in particular, however, bore a special personal resonance for him — and defied expectations.

In 2018, he set sail for the west coast of the Caribbean Sea, in the tropical Central American nation of Belize. He was intent on exploring the fabled Blue Hole, the largest oceanic sinkhole in the world — and its dangerous depths. What he would find would leave the scientific world aghast.
