Correlation of IP25 and HBI III across the MPT interval. a Pearson’s r correlation coefficient for IP25 and HBI III between 0.8 and 1.22 Ma, including the 95% confidence interval (shaded blue area), calculated using Pearson T366. The interval has been divided into three subsections based on the correlation of both biomarkers, the absolute concentration and the profile of sea ice increase across glacial periods. b IP25 (violet) and HBI III (blue) concentrations from 0.8 to 1.22 Ma expressed in ng g−1 sed
