Deep-sea corals are a unique archive in paleoceanography. They have large banded skeletons that allow for high resolution records and have a high uranium content allowing for accurate calendar ages independent of radiocarbon age measurements. However, their use as a paleoceanographic archive is complicated by the fact that the bulk isotope and trace-metal compositions of their skeletons are generally out of isotopic equilibrium with co-existing seawater. We explore the mechanisms of this 'vital' effect through 'clumped isotope' analyses of CO_2 evolved by acid digestion of natural deep-sea corals.
