Y69-71P: Chronology based on 18O correlation backed # up by radiocarbon dates. 230Th total data are corrected for standardization error # that occured at the time of measurement(*0.85). Thus, these data are different # by *0.85 from those listed in Loubere 2004. Corg% taken from Lyle et al. 2002. # ME005-27JC: Chronology based on 4 radiocarbon dates. TR163-31P: Chronology based # on benthic d18 (Martin et al. 2002). TR163-19P: Chronology based on plank d18 # (Lea et al. 2000 ) and radiocarbon dates (Spero & Lea, 2002). P7: 8 radiocarbon # dates to make chronology, ex230Th0 and Corg data published by Pedersen et al. # 1988 and Yang et al. 1995. # # Variables: # depth Depth (cm) # yrBP radiocarbon years B.P.
