Guillermo Söhnlein, co-founder of OceanGate, is spearheading a new underwater expedition to explore Dean’s Blue Hole in the Bahamas, one of the world’s deepest ocean sinkholes. The expedition, led by Söhnlein’s new company, Blue Marble Exploration, aims to send a manned submersible to the 663-foot-deep underwater sinkhole.
Challenges and Objectives


The expedition faces significant challenges, including extreme pressure, near-complete darkness, and potential unforeseen currents. However, the team is determined to explore the virtually uncharted territory, which offers opportunities to discover hidden secrets of cave-dwelling species, geological climate history, and unique ecosystems.
Expedition Team
The team includes scientist Kenny Broad and former NASA astronaut Scott Parazynski, who will gather unprecedented findings about the sinkhole, which formed approximately 15,000 years ago.
Safety Precautions
Söhnlein emphasized that the mission will use certified submersibles and involve only trained professionals, not tourists. This approach differs from the OceanGate trip last June, which ended in tragedy when the Titan submersible imploded during a dive into the Titanic wreck, killing all five aboard.
Commitment to Underwater Exploration
Despite the risks, Söhnlein remains committed to underwater exploration. Following last year’s OceanGate disaster, he stated, “Let’s figure out what went wrong, let’s learn lessons and let’s get down there again. I think it’s important for humanity.”
Expedition Details
The exact date for the Blue Marble expedition has not been announced.
