Back in early December 2018, a historical expedition was lead to the bottom of the Great Blue Hole in Belize.  Aquatica Submarines in collaboration with the Roatan Institute of Deep Sea Exploration (RIDE), Fabien Cousteau and Richard Branson took multiple submersibles and dove to the bottom of the 407ft/124m site.

After this initial expedition, 30 plus more dives took place in order to record data and footage for scientific research. 

History was made on Dec 2, 2018 when multiple submersibles dove to the bottom of the deepest sinkhole in the world, the 407ft/124m deep Blue Hole in Belize.  Located in Lighthouse Reef, approx 70 kms off the coast of Belize, the Great Blue Hole is part of the Barrier Reef Reserve System, a UNESCO World Heritage Site.
