Over a century later, and there are still plenty of mysteries tied to the tragedy of the Titanic. Researchers have spent years trying to explain what exactly happened, what caused the ship to break into two pieces, what really sealed the ship's fate before going under, why there weren't enough lifeboats, and so much more. However, researchers have been intrigued by solving certain mysteries surrounding the fatal accident, and today we have some more answers.

Around 25 years ago, divers went on a mission to retrieve remains from the Titanic in the North Atlantic Ocean, but what they found completely stumped them. These divers caught onto a mysterious sonar blip during the dive; where they thought the sonar transmission was due to another shipwreck near the remains, but now researchers have found what actually caused the blip. Over years of working towards solving the puzzling information, it is understood the "blip was caused by a rich underwater ecosystem teeming with sponges, corals, squat lobsters and fish," according to Daily Mail.

Paul Henry Nargeolet, the diver who originally recognized the blip in 1996, was a part of the expedition that returned to the underwater area this summer with no understanding of what they would find this time. Nargeolet and his team originally thought the blip was due to "another shipwreck," but instead, they were shocked to see this "fascinating volcanic formation teeming with so much life." The newly found ecosystem was discovered with a variety of "sponges, bamboo corals, other cold-water corals, squat lobsters, and fishes" 2,900 meters deep in the North Atlantic Ocean.

Thanks to the operation led by OceanGate Expedition, the mystery behind the sonar blip has finally been solved all these years later. Additionally, it will give researchers a stronger insight into the "biodiversity of the abyss," according to Dr. Steve W Ross, a chief scientist for the Expedition. "Uncovering this previously unknown ecosystem also provides an opportunity to make a comparison to the marine biology on and around Titanic," Dr. Ross added upon the discovery. So, with this in mind, we do wonder what other Titanic mysteries are left to be discovered...
