δDwax from core GeoB4905-4 in the Gulf of Guinea. a Grey timeseries represents unadjusted δDwax. Error bars are individual analytical uncertainty. Shadings indicate 68 and 95% uncertainty bounds, including a mean analytical uncertainty of 3‰ and age uncertainty. Blue timeseries represents δDwax adjusted for ice volume, shading as above. b δDwax adjusted for ice-volume and vegetation-type changes, representing an estimate of past δDp. Shadings as above. Thick black line is the Ruppert-Sheather-Wand smooth, the optimal smoothing for the data set86. c Rate of change (‰ kyr−1) based on Ruppert-Sheather-Wand smooth. Blue colours representing periods of wettening, red represent periods of aridification. Red diamonds mark calibrated radiocarbon age control points. Vertical bars highlight the African Humid Period (AHP), Younger-Dryas (Y-D) and Heinrich Stadials 1 and 2 (HS1, HS2)
