Bering Sea biomarker patterns across the three studied Pleistocene intervals. Overview of the three time intervals analysed for biomarkers. a 0.34−0.5 Ma, b 0.8−1.22 Ma and c ~1.36–1.53 Ma. Sedimentary mass accumulation rate of biogenic opal (MARopal) in Site U1343 is in purple36. IP25 (violet) and HBI III (blue) in Site U1343 are expressed in ng g−1 dry sediment (sed). The benthic foraminiferal oxygen isotope record of Site U134342 is in black together with the LR04 stack16 in grey. The light grey vertical bars indicate glacial intervals and the white bars characterise interglacials (numbers at the top correspond to MISs, MIS boundaries from Lisiecki and Raymo16). The yellow asterisk indicates the first glacial interval where a late-glacial/deglacial sea ice maximum is observed (MIS 28)
