21,000-Year-Old Underwater Mystery Solved off Corsica

Mysterious Underwater Rings off Corsica Reveal Ancient Ecosystem and Climate History Off the coast of Corsica, a recent scientific expedition has unveiled an extraordinary discovery: perfectly aligned underwater formations that are far older and more complex than initially thought. These rings, first detected on sonar in 2011, were initially a source of speculation. However, a team of scientists, led by renowned diver Laurent Ballesta, used a state-of-the-art submarine and underwater station to explore the formations at depths exceeding 120 meters. "It was truly incredible," said one of the participating scientists. "The scale and complexity of the structures were unlike anything we've ever seen before." The investigation revealed that the rings are composed of three distinct elements: a central rocky core, a disc of light sand, and a dark crown of colorful pebbles. Detailed analysis using advanced technologies determined that the central cores are approximately 21,000 years old, dating back to the last glacial period. The outer crowns, however, are significantly younger, formed around 8,000 years ago. This discovery provides invaluable insight into the Mediterranean's climate history and the evolution of its marine ecosystems. The unique biodiversity found within and around the structures highlights the resilience of life in even the most extreme environments. The research not only solved the mystery of the Corsican rings but also added a significant piece to the puzzle of understanding past climate change and its impact on marine life.
