The response of the tropical ocean to global climate change and the extent of sea ice in the glacial nordic seas belong to the great controversies in paleoclimatology. Our new reconstruction of peak glacial sea surface temperatures (SSTs) in the Atlantic is based on census counts of planktic foraminifera, using the Maximum Similarity Technique Version 28 (SIMMAX-28) modern analog technique with 947 modern analog samples and 119 well-dated sediment cores. Our study compares two slightly different scenarios of the Last Glacial Maximum (LGM), the Environmental Processes of the Ice Age: Land, Oceans, Glaciers (EPILOG), and Glacial Atlantic Ocean Mapping (GLAMAP 2000) time slices. The comparison shows that the maximum LGM cooling in the Southern Hemisphere slightly preceeded that in the north. In both time slices sea ice was restricted to the north western margin of the nordic seas during glacial northern summer, while the central and eastern parts were ice-free. During northern glacial winter, sea ice advanced ... : Supplement to: Pflaumann, Uwe; Sarnthein, Michael; Chapman, Mark R; de Abreu, Lucia; Funnell, Brian M; Hüls, Matthias; Kiefer, Thorsten; Maslin, Mark A; Schulz, Hartmut; Swallow, John; van Kreveld, Shirley A; Vautravers, Maryline J; Vogelsang, Elke; Weinelt, Mara (2003): Glacial North Atlantic: Sea-surface conditions reconstructed by GLAMAP 2000.
