A joint expedition by Argentine and U.S. scientists has explored the Mar del Plata submarine canyon in the South Atlantic Ocean at a depth of approximately 4,000 meters (about 13,123 feet). The mission, which was livestreamed, revealed previously unseen deep-sea creatures and captivated a wide audience. This exploration has sparked discussions about the future funding of national science programs in Argentina. The findings contribute to a growing understanding of deep-ocean ecosystems, including genetic studies of species such as brittle stars that suggest species exchange routes in the deep sea. The mission highlights the potential for artificial intelligence to assist in mapping hidden marine ecosystems. The discovery adds to a broader narrative of uncovering unknown marine life and ancient natural wonders preserved underwater.
