a: Correlation with GISP2 oxygen isotope record (Grootes and Stuiver, 1997).
b: The age model of the core AD91-17 is based on AMS 14C, planktonic isotopic record from Capotondi et al. (1999) and the correlation with MD90-917 planktonic isotopic record (Siani et al., 2001).
c: Comparison with ODP 963 data from the same location (Sprovieri et al., in preparation)
d: The age model was obtained by correlation of the planktonic d18O records with those reported from Capotondi et al. (1999).
e: The age model was obtained by correlation of the planktonic d18O records with the standard SPECMAP composite record from Martinson et al. (1987).
f: The age model was obtained by correlation of the benthic d18O record with the composite records of Shackleton (2000).
g: The age model was obtained by correlation of the planktonic d18O records with the standard SPECMAP composite record from Imbrie et al. (1984).
h: The chronology was obtained by attributing ages to the key stratigrahic events identified in other cores from the North Atlantic with detailed radiocarbon chronologies.
i: Correlation between planktonic d18O records of core MD77194 and core 74KL (Sirocko et al., 1993).
j: Correlation of the benthic d18O with the standard LR04 composite record of benthic foraminifera from Lisiecki and Raymo (2005)
k: The age model for the last 8ka was obtained by correlation of Ca XRF and magnetic susceptibility measurements with those reported in the radiocarbon-dated GeoB3313-1 at the same location (Lamy et al., 2001)
l: Correlation between core TN057-21 d18O records of (i) benthic forams and SPECMAP (Ninnemann and Charles., 2002) and (ii) planktonic forams and RC 1183 (Charles et al., 1996)
m: Based on Shackleton, 2000, Science (benthic stratigraphy) and in agreement with 6 radiocarbon ages (G. Bond, unpublished data)
n: The correlation is based on comparison of downcore CaCO3 measurements
