In a first-of-its-kind deep-sea exploration, researchers from the Australian National University have made stunning discoveries in the newly formed marine park off the coast of Australia. The team employed a remotely operated vehicle to survey the ocean floor up to depths of 4,000 meters (13,000 feet) and came across an array of marine life that has left scientists astounded.
This groundbreaking research voyage was conducted in Australia’s Cocos Islands’ Marine Park, where the scientists mapped the seafloor in detail for the first time. During this expedition, which spanned from September to November 12, the team discovered “massive flat-topped ancient sea-mountains” formed by avalanches of sand that have slumped down onto the ocean floor. These formations were previously unknown and represent a significant geological find1.
The team also encountered an incredible diversity of marine life. According to Museums Victoria, Australia’s largest public museum organization and research institute, the underwater video footage revealed a previously unknown blind eel, deep-sea batfishes, and Pancake sea urchins. Interestingly, the researchers also found pumice stones, believed to be remnants of the historic 1883 eruption of Krakatoa in Indonesia1.
“We have discovered an amazing number of potentially new species living in this remote marine park,” said the institute’s chief scientist, Dr. Tim O’Hara. He added that they were proud their maps, data, and images would be used by Parks Australia to manage the new marine park in the future1.
Moreover, the team produced three-dimensional images of the mountain underneath the Islands, a region that had never been mapped in detail before. These 3D maps and underwater video images were directly transmitted to the people of Cocos (Keeling) Islands, who expressed great excitement at seeing their seascape in all its grandeur for the first time1.
The discoveries were made possible after the Australian government proclaimed two marine parks across the country’s Indian Ocean territories in March. This investigation has led to many significant discoveries of marine life and deep ocean terrain, making it an important milestone in marine research. “We are very proud of this work,” said Museums Victoria CEO Lynley Crosswell, underscoring the significance of the research voyage1.
As researchers continue to investigate the findings, it is clear that this exploration has opened a new chapter in our understanding of the deep sea and its diverse, often surprising, inhabitants. The insights from this voyage not only expand our knowledge of marine biology but also offer invaluable data for the sustainable management and conservation of these newly formed marine parks.
