Oceanographers have recently confirmed that Mexico’s Chetumal Bay is home to the world’s deepest underwater sinkhole, known as the Taam Ja’ Blue Hole. This abyss is at least 420m deep, making it deeper than other famous blue holes such as the Dragon Hole in South China Sea.
Blue holes form when water seeps through cracks in the seafloor, dissolving minerals and creating sinkholes. The discovery of this massive blue hole was initially met with skepticism, but a more intensive study revealed its true depth using new technology and diving techniques. Researchers anchored a vessel near the hole and dropped a line to measure its depth, while also diving with instruments to profile the water’s conductivity, temperature, and depth.
The results were astonishing – the Taam Ja’ Blue Hole is at least 420m deep, but it could be even deeper. The water in the hole has layers of varying temperature and salinity, with one layer at around 400m deep having values similar to those found in nearby Caribbean Sea. This suggests that there may be an underwater seabed connecting these two seas.
Researchers believe that this unique biodiversity within the depths of this blue hole may be waiting to be discovered and linked to physicochemical and geomorphological processes. The mystery surrounding this abyss continues to intrigue scientists around the world as they strive to uncover its secrets.
