1. Exploring how corals build their skeletons

Despite its long history of study, the mechanism by which corals form their skeletons remains largely unknown. Recently, advances in microanalytical techniques have made it possible for scientists to investigate the variability of trace elements and stable isotopic compositions within coral skeletons. These studies have revealed systematic compositional variations within skeletons that are much too large to be explained by anything but biological activity. Such data complicate the use of corals as prox
