Orange cup corals

Caption

Orange cup corals, pictured growing on rocks above, are native to the Pacific Ocean. As they grow, the corals incorporate minerals from seawater, leaving a valuable historical record in their skeletons. In this University of Washington-led study, the researchers compare preindustrial corals to modern specimens to show how quickly the ocean is acidifying.
