The purpose of this study was to re-evaluate the paleo sea-ice record for marine sediment core SO136-111. We applied a generalized additive model, and compared the estimates from GAM with those estimates derived from weighted averaging partial least squares, the Imbrie and Kipp Transfer function and the Modern Analogue Technique. We provide the first record of paleo winter sea-ice concentration data for core SO136-111, based on a diatom proxy. Core SO136-111 provides a record for winter sea-ice concentrations over the last 220 kyr BP.

Gravity core SO136-111 (56°40'S, 160°14'E, water depth 3912 m) was retrieved from the Emerald Basin, in the East Indian sector of the Southern Ocean south of the modern Antarctic Polar Front. The core was retrieved in 1998 during the TASQWA cruise on board the FS SONNE.
