Notes: 
1)A 400-yr correction is applied for the reservoir age of sea water, 
although its precise age range is unknown in the South China Sea 
(Stuiver & Braziunas, 1993). 
2)Converted calendar age (Stuiver & Becker, 1993, Stuiver & Pearson, 1993); 
3)age range at minor 14C plateau; 
4)converted calendar age (Pearson et al., 1993); 
5) converted calendar age (Kromer et al., 1993); 
6) age range at major 14C plateau (Bard et al., 1990); 
7)calendar age of the top of the Younger Dryas (Alley et al., 1993); 
8)converted calendar age (Bard et al., 1990, Winn et al., 1991). 
9)averaged cal. ages used in smooth-spline fit (see text for discussion).
