The stalagmite carbonate record, dated by the U-Th geochronometry technique, includes higher d18O and d13C values within Heinrich stadials 1, 2, and 3 followed by rapid declines at the end of the stadials. To aid in the interpretation of these results, the d18O of fluid inclusions associated with the Heinrich stadials were also analyzed. These measurements, which allowed for the relative influence of temperature and d18O of precipitation to be distinguished, demonstrate minimal changes in the d18O of fluid inclusions, suggesting that changes in the d18O values of the speleothem carbonate associated with Heinrich stadials 1-3 are principally driven by an average ~4C temperature decrease, rather than a change in the d18O of the rainfall (hence rainfall amount). These findings support previous work in the North Atlantic and are consistent with the climate response to a weakening of the Atlantic meridional overturning circulation.","author":{"name":"Monica M.
