Taam Ja Blue Hole Discovered

Taam Ja Blue Hole Discovered:

Scientists have discovered a massive blue hole off the coast of the Yucatan Peninsula in Mexico.

  • It is a type of underwater sinkhole or vertical cave that is typically found in low-lying coastal karst platform regions.
  • These are formed when limestone or other carbonate rock is dissolved by slightly acidic groundwater over a long period.
  • Taam Ja Blue hole is around 900 feet deep and scientists have dubbed it the second-deepest blue hole found on the planet.
  • It has a nearly circular shape at its surface with steep sides that form a large conic structure covered by biofilms, sediments, limestone, and gypsum ledges.
  • It was found in the central portion of Chetumal Bay, where submerged coastal karstic sinkholes locally named ‘pozas’ have been reported.
  • A series of discontinuous terraces were detected at water depths, near the eastern and north-western walls of the blue hole before developing steep and almost vertical slopes.
  • There is variation in salinity and temperature inside the blue hole.
  • Yucatan Peninsula is a Northeastern projection of Central America which is lying between the Gulf of Mexico to the west and north and the Caribbean Seato the east.
  • The peninsula is almost wholly composed of beds of coralline and porous limestone rocks.
