Cold-water coral skeleton fluid inclusion δ18O and δ2H environmental and calcification impacts

This dataset contains fluid inclusion hydrogen (δ2H) and oxygen (δ18O) isotope compositions from cold-water coral skeletons, collected from Holocene and last glacial period deposits in Angola and Iceland. The data were obtained through comparative measurements using cavity ringdown spectroscopy (CRDS) and isotope ratio mass spectrometry (IRMS) techniques. The dataset includes results from coral skeletons processed at various temperatures (with a focus on 120°C), highlighting the influence of kinetic isotope fractionation on the isotopic compositions during coral crushing.
