Taam Ja Blue Hole

• Researchers have found the world’s deepest blue hole in the Latin American country of Mexico.
• They have reached 1,380 feet or 420 meters below sea level, but it is not the end of the hole.
• According to the study published in the journal ‘Frontiers in Marine Science’, the “deepest known blue hole” Taam Ja’ Blue Hole (TJBH), is located in Chetumal Bay off the Yucatan Peninsula.
• Taam Ja’ Blue Hole is 480 feet deeper than what scientists documented in 2021.
• It is also 390 feet or 119 meters deeper than the previous record holder — the 990-foot-deep Sansha Yongle Blue Hole, also known as the Dragon Hole, located in the South China Sea.

ABOUT BLUE HOLE

• Blue holes are water-filled vertical caverns, found in coastal regions where the bedrock is made of soluble material, such as limestone, marble, or gypsum.
• Blue holes typically contain tidally influenced water of fresh, marine, or mixed chemistry.
• They extend below sea level for most of their depth and may provide access to submerged cave passages.
• Examples include
  • the Dragon Hole in the South China Sea.
  • the Great Blue Hole and Dean’s Blue Hole in the Caribbean.
  • the Dahab Blue Hole in Egypt and
  • the Great Blue Hole in Belize.
