A deep dive into Belize's Blue Hole reveals stunning discoveries

The Great Blue Hole, located off the coast of Belize, has long fascinated scientists. When divers finally reached its bottom, they discovered something shocking.

The Great Blue Hole is a massive marine sinkhole in the Caribbean, situated off the coast of Belize. Its diameter is 1,043 feet, and its depth reaches 407 feet. This impressive formation attracts both tourists and researchers, making it one of the country's most significant attractions.

For many years, the lack of appropriate equipment prevented the thorough exploration of the Great Blue Hole. It wasn't until an expedition in 2018 that valuable information about this underwater formation and ourselves was obtained. When the Aquatica Submarines crew reached the bottom, they discovered something disturbing.

Initially, the divers observed corals, reef sharks, and sea turtles. However, life began to vanish at 295 feet due to a thick hydrogen sulphide layer blocking oxygen from reaching deeper parts.

Erika Bergman, a participant in the Aquatica Submarines expedition, admitted that they found shells and hermit crabs that had fallen into the hole and suffocated. The most shocking discovery, however, was the presence of human trash at the bottom of the Great Blue Hole.

The research team encountered a cola bottle that had reached a depth of 407 feet, as well as a GoPro camera with vacation photos. Among the debris, they also found the bodies of two divers who were likely lost during previous expeditions.

During the research, they also discovered stalactites—rock formations hanging from the ceiling of the cave. This finding suggests that the Great Blue Hole was once a dry cave that formed around 14,000 years ago. It was later flooded and collapsed after the Ice Age ended when sea levels on Earth rose.
