The deepest blue hole on Earth plunges over 400 meters into a narrow bay in the Yucatan Peninsula. And oceanographers haven’t even found the bottom yet. Taam Ja’ Blue Hole took over the title of the world’s deepest blue hole — an underwater sinkhole — on April 29,

Researchers have found a blue hole they say is the deepest in the world—and they’ve yet to find where it bottoms out. The formation is the Taam Ja’ Blue Hole in Mexico’s Chetumal Bay, and it has so far been measured to 1,

Scientists have yet to reach the bottom of the Taam Ja' Blue Hole in Mexico's Chetumal Bay, which new measurements hint could be connected to a labyrinth of submarine caves and tunnels.

Initially thought to be the world's second deepest, researchers now say the Taam ja' blue hole is 480 feet deeper than they first believed.

In a groundbreaking discovery, explorers and scientists have unveiled the world's deepest known blue hole located off the coast of Mexico's Yucatan Peninsula. This extraordinary natural phenomenon, plunging deeper into the Earth's crust than any previously recorded blue hole,

A small team of oceanographers from several institutions in Mexico has found evidence that the Taam Ja' Blue Hole in Mexico's Chetumal Bay, on the eastern side of the Yucatán Peninsula, is the deepest in the world.

Taam Ja’ Blue Hole (TJBH), is located in Chetumal Bay off the Yucatan Peninsula and it is estimated to be at least 1,380 feet (420 metres) below sea level. This makes TJBH the deepest known underwater sinkhole in the world.
