Comment:
Dating method:
(a) radiocarbon + correlation with nearby MD98-2176
(b) AMS 14C on ME-43JC; ODP1242 is correlated with ME43-JC through comparison of d18O. Mg/Ca and sediment density data; SST of both sequences are together
(c) The chronology was obtained by attributing ages to the key stratigrahic events identified in other cores from the North Atlantic with detailed radiocarbon chronologies.
Calibrations:
Lea et al. (2000): Mg/Ca = 0.3 exp(0.089T) (core top calibration)
Dekens et al. (2002): Mg/Ca = 0.38 exp(0.09T) (core top calibration)
Anand et al. (2003): Mg/Ca = 0.38 exp(0.09T) (sediment trap calibration)
Nürnberg et al. (1996): Mg/Ca = 0.38 exp(0.091T) (culture experiments)
Mashiotta et al. (1999): Mg/Ca = 0.474 exp(0.107T) (culture experiments)
Hastings et al. (2001): Mg/Ca = 0.38 exp(0.089T) (core top calibration)
von Langen et al. (2005): Mg/Ca = 0.51 exp(0.1T) (culture experiments on N. pachyderma (d))
Elderfield and Ganssen (2000): Mg/Ca = 0.52 exp(0.1T) (core tops)
Barker and Elderfield (2002): Mg/Ca = 0.72 exp(0.1T) (core tops)
Thornalley et al. (2009): Mg/Ca = 0.794 exp(0.1T) (core tops)
