Corrigendum to "Highly branched isoprenoids reveal onset of deglaciation followed by dynamic sea-ice conditions in the western Amundsen Sea, Antarctica" [Quat. Sci. Rev. 228 (2020) 106103]

After publication of the article, the authors noticed a mistake in the concentration calculations of the two biomarker lipids IPSO₂₅ and dinosterol. The volume of the internal standards 7-hexylnonadecane and 5α-androstan-3-ol had incorrectly been calculated twice. Hence, the absolute concentrations of IPSO₂₅ are erroneously higher by factor 20 and the concentrations of dinosterol are erroneously higher by factor 60. The calculated P_DIPSO₂₅ index is not affected by these changes.
