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 PDIPSO25 index is not affected by these changes.
