integrationTimeBasis: The age of colony CF1B was determined by 230Th/U-dating following established methodology (Edwards et al., 1987; Shen et al., 2002).Three dates were performed at the top, middle, and bottom of the CF1B core. All ages were corrected for the effect of detrital Th contamination assuming a bulk earth 232Th/238U weight ratio of 3.8 for the detritus and 230Th, 234U, and 238U in secular equilibri- um. The reliability of the determined 230Th/U-ages was verified using established criteria such as initial 234U/238U in agreement with 234U/ 238U of modern seawater (i.e., 146 � 3?)

The high-density bands were equivalent to summer and low density to winter. The coral d18O record of Kuhnert et al. was averaged annually (January?December), and then each individual annually resolved coral proxy record was normalized to its variance relative to the 1900?1993 reference period. We used the COFECHA tool to aid in cross-dating the annual time series. We aligned the new annually resolved Sr/Ca and d18O records (normalized relative to the 1900?1993 reference period) with the Kuhnert et al. annual time series, and averaged all records to form a composite chronology that extends from 1795 to 2010."
