Deepest Blue Hole In The World Discovered In Mexico's Chetumal Bay

Researchers have discovered the world's deepest known undersea blue hole. And they have yet to reach the bottom. According to measurements by the team, the Taam Ja' Blue Hole (TJBH), which is located in Chetumal Bay off the southeast coast of the Yucatan Peninsula in Mexico, is at least 1,380 feet (420 metres) below sea level. 'Taam Ja' translates to 'deep water' in Mayan. The measurements are just short of the record set by the world's deepest known blue hole, the Dragon Hole in the South China Sea, which was discovered in 2016 and is estimated to be more than 980 feet (300 metres) deep.
