The age model for Site-1085 was determined by correlation # of the benthic delta18O data to the LR04 curve. d18O values have been corrected # to a common 'Uvigerina' scale by adding 0.64permil. Some d13C data from Site-1085 # are on the basis of measurements of Uvigerina spp. corrected to C. wuellerstorfi # values by adding 0.9permil. # # GeoB1720-2 C14 Dates # # yrBP radiocarbon years B.P.
