Seasonal changes in sediment core PS1795-2, supplement to: Sprenk, Daniela; Weber, Michael E; Kuhn, Gerhard; Wennrich, Volker; Hartmann, Thomas; Seelos, Klemens (2014): Seasonal changes in glacial polynya activity inferred from Weddell Sea varves. Climate of the Past, 10(3), 1239-1251


The Weddell Sea and the associated Filchner-Rønne Ice Shelf constitute key regions for global bottomwater production today. However, little is known about bottom-water production under different climate and icesheet conditions. Therefore, we studied core PS1795, which consists primarily of fine-grained siliciclastic varves that were deposited on contourite ridges in the southeastern Weddell Sea during the Last Glacial Maximum (LGM). We conducted high-resolution X-ray fluorescence (XRF) analysis and grain-size measurements with the RADIUS tool (Seelos and Sirocko, 2005, doi:10.1111/j.1365-3091.2005.00715.x) using thin sections to characterize the two seasonal components of the varves at sub-mm resolution to distinguish the seasonal components of the varves.
