Researchers at National Taiwan University and partner institutions have uncovered new evidence that Antarctic Intermediate Water (AAIW)—a distinct layer sitting 500–1,500 meters below the ocean surface—played a pivotal role in a major atmospheric carbon dioxide transition that occurred roughly 450,000 years ago.
