The pattern of precipitation bears a striking resemblance to the oxygen-isotope record from Greenland ice cores, with increased tropical precipitation associated with warm periods in the high northern latitudes. The largest change, at the onset of interstadial 12, occurred very rapidly, in about 25 years. The chronology of the events found in our record requires a reevaluation of previously published time scales for climate events during this period. STUDY NOTES: High resolution stalagmite oxygen isotope data from Socotra Island in the Indian Ocean, providing a record of changes in monsoon precipitation from 53 - 40 KYrBP, Dansgaard/Oeschger Events 9 to 13. The stable isotope time series published in Burns et al., 2003 was later revised based on a corrected chronology as explained in Burns et al., Science, 2004. The data archived here are on the revised chronology. NCDC-Paleoclimatology https://www.ncdc.noaa.gov/data-access/paleoclimatology-data - Bauer Bruce Investigator : Burns, S.J.
