Quaternary Science Reviews 26, 2316-2321. Data comments: 23°W in Table 1 changed to 22°W to get the longitudes correct. Sample thickness back-calculated based on thickness correction in Table 1. 10Be standard assumed to be NIST_30300 based on information in Håkansson et al. (2009). Sampling year assumed to be 2005. One group ID for all samples (all samples from one location). expage.github.io - data from expage-202306
