The World's Deepest Blue Hole Is Located In South China Sea
In the course of over a year of exploration, Chinese scientists have determined that the blue hole located at Xisha Island, also known as Parcel Island in the South China Sea, is the deepest sinkhole in the world.
In a report by Xinhua News, Fu Liang, head of the Sansha Ship Course Research Institute for Coral Protection, has confirmed that the blue hole is 987 feet deep and 426 feet wide in diameter at the entrance, surpassing the previous record holder with a depth of 663 feet, the Dean's Blue Hole of Long Island, Bahamas.
The researchers used an underwater robot equipped with a depth sensor to explore and measure the depth of the underwater sinkhole.
The team found out that it is inhabited by various species of marine animals and organisms at shallow level. It is oxygen free below 100 feet from the water surface so life is doubtful to exist in the deepest part of the hole.
