A new dataset called EIRA (Easter Island Radiocarbon Ages) has been recently presented by V. Rull in Frontiers in Ecology and Evolution (Front. Ecol. Evol., 26 April 2016). The EIRA database contains all the radiocarbon ages from Aroi, Kao, and Raraku sediments published to date (1984–2015) and can be freely accessed at NOAA !

As described by the author in this paper: “The EIRA database provides paleoecologists and paleoclimatologists with a thorough chronological dataset to be analyzed statistically as a whole or by parts (by sites, by age intervals, etc.), aimed at contributing to the development of new age-depth models, reconsider the existing ones, or plan new studies and coring campaigns“. Thank you to the author for this open source database!
