Fig. 2: Sedimentary record of abrupt terrestrial carbon deposition at the onset of the B-A.
From: Coastal permafrost was massively eroded during the Bølling-Allerød warm period
Main data plotted against calibrated age. a Estimated sea level curve (ESL, blue line), showing 1σ error bars as shaded area102. b Oxygen isotopes (δ18O) from Greenland ice cores119 (black line). c Lignin phenols Mass Accumulation Rate (MAR) from core HH11-09GC (orange line and dots) and (d) from core 31-PC (brown line and dots)22. e Cutin-derived products MAR (green line and dots) from core HH11-09GC. f CPI of n-alkanes from core HH11-09GC (red line and dots) and (g) from core PS2138-133 (green line and dots). h High molecular weight (HMW) n-alkanes MAR from core HH11-09GC (orange line and dots) and (i) from core 31-PC (brown line and dots)22. j Relative content of smectite in the clay fraction of core PS2138-133 (brown bars). The vertical dashed line displays the onset of MWP-1A.
