Fig. 4: Geochemical and bulk sediment properties of core HLY1302 JPC-15/27 for the late Bølling–Allerød, the Younger Dryas and early Holocene.

From: Arctic drainage of Laurentide Ice Sheet meltwater throughout the past 14,700 years

Fig. 4

Data are shown against age (ka). a and b Authigenic (red) as well as detrital (dashed blue) 208Pb/204Pb (a) and 206Pb/204Pb (b) signature. c Stable oxygen isotope data (δ18O) in ‰ of planktonic foraminifera N. pachyderma s. and d magnetic susceptibility6. e ARM30mT record of JPC-15/27 complemented with f the ARM30mT/ARM0mT ratio of the same samples. g NGRIP δ18O69. Light yellow areas indicate major Lake Agassiz drainage events through the Mackenzie River.
