A team of scientists and engineers has found a weird and deadly lake 3,300 feet below the surface of the Gulf of Mexico. The underwater lake dubbed as “Jacuzzi of Despair,” was first observed in 2014 while a team was exploring the seafloor in the gulf of Mexico using Hercules, a remotely-operated underwater robot. A year after its first appearance, the researchers were so curious that they sent a special vehicle sub Alvin into the pool’s depths only to discover that it’s deeper than they expected.
According to their findings published in journal Oceanography, the underwater pool is littered with living mat of bacteria and salt deposits. The massive circular pool is about 100 feet in circumference and about 12 feet deep.
“It was one of the most amazing things in the deep sea,” Erik Cordes, associate professor of biology at Temple University and one of the scientists who discovered the underwater lake, told The Seeker. “You go down into the bottom of the ocean and you are looking at a lake or a river flowing. It feels like you are not on this world.”
In fact the waters inside the pool is four to five times saltier and relatively warmer than its surroundings, that’s why any marine animal accidentally wandered into pool die instantly. The warmer temperature of the pool also contributes to the luring effect of the brine that serves as the place of death of many crustaceans. Carcasses of deep-sea crabs and other crustaceans can be found in the rim. Due to the high toxicity produced by the combination of methane gas and hydrogen sulfide, the lake can only be populated by bacteria and a couple of adaptive marine creatures.
One of very rare animals living within the deadly pool are the giant mussels with symbiotic bacteria living in their gills. This type of bacteria can feed the giant mussels off the hydrogen sulfide and methane gas in the pool. Few more creatures spotted to be living in the toxic underwater lake include adapted tube worms and shrimps.
