(CNN) – The wreck of the Titanic sits in two parts at the bottom of the North Atlantic Ocean, slowly decaying nearly 13,000 feet (4,000 meters) below the surface, but it’s not alone.
A sonar blip detected around 26 years ago has now revealed there’s much more to this underwater area than previously thought.P.H.
Nargeolet, a veteran Nautile submersible pilot and Titanic diver, originally picked up the blip on echo sounding equipment in 1996, but its origins have remained unknown.In an expedition to the Titanic shipwreck earlier this year, Nargeolet and four other researchers went to the blip’s previously recorded location to search for the mysterious object it represented.
Due to the blip’s magnitude, Nargeolet had believed he was looking for another shipwreck — he instead found a rocky reef, made up of various volcanic formations, and thriving with lobsters, deep-sea fish, sponges, and several species of coral that could be thousands of years old.“It is biologically fascinating.
