We directly used the observed leads of sea surface temperature with respect to air temperature (dated in calendar years), whereas the air temperature calendar ages should have been converted into 14C ages, with reservoir ages computed as the difference between marine and atmospheric 14C ages. Taking this into consideration, apparent surface-water ages are 1,180 ± 630 to 1,880 ± 750 years at the end of the Heinrich 1 surge event (14,500 years bp) and 930 ± 250 to 1,050 ± 230 years at the end of the Younger Dryas cold episode. This does not change the discussion and conclusions.
