Precise measurement of boron isotopes in skeleton reve...
(WorldNews Asia)

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...
