Researchers at the University of Tokyo and their collaborators have revealed that boron isotope ratios in skeletons of long-lived reef-building corals, called Porites, in the western North Pacific Ocean are experiencing a rapid decrease in recent years. The group used coral skeletons collected from Japan's Chichijima and Kikaijima islands, in the Ogasawara and Amami archipelagoes, respectively, to analyze the boron isotope ratios, which reflect the pH (acidity) of the skeletons' calcification fluid. This finding promises to provide important insights for projecting the future response of coral reef ecosystems to climate change caused by humans.
