The relative abundance of C37:4, C37:3, and C37:2 alkenones and the calculated sea surface temperature based on \( {U}_{37}^{\mathrm{k}} \) and \( {U}_{37}^{\mathrm{k}\prime } \) index at different depths of the core R23. The light gray and light blue bands represent modern average summer SST based on the World Ocean Atlas (WOA09) data set (Locarnini et al. 2010) and highest SST during the Holocene at the same latitude of the Southern Ocean from previous studies (Kim et al. 2012; Etourneau et al. 2013), respectively
