Notes: YD = Younger Dryas, IS = GISP2 interstadial equivalent. LO = last occurrence. Ages of last 110 k.y. are based on the Meese/Sowers timescale (Meese et al., 1994). H1–H6 = Heinrich event analog. Ages of MIS 6–34 are based on Shackleton et al. (1990) and Bassinot et al. (1994); nannofossil ages after to Shipboard Scientific Party (2000).
