Thriving Ecosystem Discovered Beneath Calved Antarctic Iceberg
2025-03-25
Scientists exploring the seafloor exposed by the calving of the massive A-84 iceberg (Chicago-sized) in Antarctica discovered a surprisingly vibrant ecosystem. Using the ROV SuBastian, they found large corals, sponges, icefish, giant sea spiders, and octopuses, suggesting these communities have existed for decades, perhaps centuries. This unexpected discovery challenges existing understanding of how icebergs affect their surroundings and highlights the impact of Antarctic ice sheet melt. Ocean currents are believed to be crucial for life under the ice, while the shrinking ice sheet poses a threat. The research provides crucial data for predicting future climate change impacts.
