英文摘要	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. In 4.1.2. Unit B: Dynamic ice front The value for IPSO25 was reported as 4–8 μg∗g OC−1, but should now be corrected to 0.2–0.4 μg∗g OC−1. The value for dinosterol was reported as 200–400 μg∗g OC−1, but should now be corrected to ca 2–7 μg∗g OC−1. In 4.1.3. Unit C: Reduced sea-ice cover followed by sea-ice re-expansion In subunit C1, the value for dinosterol was reported as 180 μg∗g OC−1, but should be corrected to 3 μg∗g OC−1. In subunit C2, the value for IPSO25 was reported as 6–16 μg∗g OC−1, but should be corrected to 0.3–0.8 μg∗g OC−1. In subunit C2, the value for dinosterol was reported as 300–600 μg∗g OC−1, but should be corrected to 5–10 μg∗g OC−1. In 4.1.4. Unit D: Seasonal sea-ice cover environment In subunit D1, the value for IPSO25 was reported as ca 1 μg∗g OC−1, but should be corrected to ca 0.05 μg∗g OC−1. In subunit D1, the value for dinosterol was reported as 100–400 μg∗g OC−1, but should be corrected to ca 1–7 μg∗g OC−1. In subunit D2, the value for IPSO25 was reported as 0–12 μg∗g OC−1, but should be corrected to 0–0.2 μg∗g OC−1. In subunit D2, the value for dinosterol was reported as 200–500 μg∗g OC−1, but should be corrected to ca 3–8 μg∗g OC−1. Please note that the values of the IPSO25 and dinosterol axes in Fig. 2. and the corresponding supplementary figure plotted versus age (printed below) are now corrected. Datasets uploaded to PANGAEA Data Publisher for Earth & Environmental Science have also been corrected (https://doi.org/10.1594/PANGAEA.904263). The changes have no impact on the scientific results and reasoning presented in the paper. [Figure presented] Fig. 2. Contents of PDIPSO25 (a), dinosterol (b), IPSO25 (c) and TOC (d) in sediment core PS69/274-1. AMS 14C age constraints in calib. a before present (BP) in dark grey; unreliable age given in italics (Hillenbrand et al., 2010). Interval highlighted by dashed grey line marks the Antarctic Cold Reversal (ACR; Jouzel et al., 1995). Biomarker concentrations and calculated PDIPSO25 value of the surface sample (box core PS69/275-2) indicated by dots with black circle and label in respective color. Triangles in PDIPSO25-curve: thick ice cover, maximum value of 1 assigned to these samples. Core is divided into four units as indicated in the lowermost and topmost bar: Unit A: floating ice canopy (blue shading), Unit B: dynamic ice front, Unit C: reduced sea ice/sea-ice re-expansion (red shading), Unit D: seasonal sea ice.
