Separation of kinetic and metabolic isotope effects in carbon-13 records preserved in reef coral skeletons
Abstract
The stable isotopic signatures of Jamaica and Zanzibar coral skeletons, collected over depth and light gradients, are strongly affected by kinetic isotope effects associated with the calcification process. These kinetic effects mask δ13C metabolic signals of light availability/photosynthesis. A simple data transformation, based on oxygen isotopic variation in the skeleton, has been developed to correct for the presence of these disequilibrium …
