Coring Corals

Woods Hole Oceanographic Institution scientist Anne Cohen (left) and Nathan Mollica, a graduate student in the MIT-WHOI Joint Program, extract core samples from a giant Porites coral in Risong Bay, Palau. They and WHOI scientist Weifu Guo were co-authors of a study that identified a detailed mechanism showing how ocean acidification affects the growth of coral skeletons. It gives scientists a way to predict more precisely where corals will be more vulnerable. The study was published Jan. 29, 2018, in the Proceedings of the National Academy of Sciences.
