Sea surface temperature reconstructions of sediment cores from the Atlantic sector of the Southern Ocean, supplement to: Brathauer, Uta; Abelmann, Andrea (1999): Late Quaternary variations in sea surface temperatures and their relationship to orbital forcing recorded in the Southern Ocean (Atlantic sector). Paleoceanography, 14(2), 135-148
Late Quaternary summer sea surface temperatures (SSTs) have been derived from radiolarian assemblages in the East Atlantic sector of the Southern Ocean. In the subantarctic and the polar frontal zone, glacial SSTs (oxygen isotope stages 2, 4, 6, and 8) were 3°-5°C cooler than today, indicating north...
