Comparison of PBIP25 and PDIP25 signals of sediment core JM11-FI-19PC (GICC05-timescale) and sediment core MSM5/5-712-2 (calibrated age scale) from the Svalbard margin published by Müller and Stein17. For H-event 1 (blue bar), characterized by IP25 and brassicasterol (as well as dinosterol) values of close to or zero (that is, ‘zero divided by zero’), per definition maximum PBIP25 and PDIP25 values of 1 were assumed (for background see refs 15, 26). For core locations, see Fig. 1. BA, Bølling and Allerød interstadial; H, H-event; HS, Heinrich stadial; LGM, Last Glacial maximum; YD, Younger Dryas.
