Abstract
Previous studies of coupled Mg/Caforam and δ18O measurements across the transition from the last glacial period to the Holocene, Termination 1, in tropical settings have shown that the planktonic Mg/Ca signal leads the δ18O signal by several thousand years (e.g. Lea et al., [2000]; Nürnberg et al., [2000]; Visser et al., [2003]). This leads to the conclusion that the tropical ocean warmed before the melting of Northern Hemisphere ice sheets challenging the role of the North Atlantic as the pacemaker of glacial/interglacial transitions and emphasizing the tropical ocean as an important area for triggering global climate change. This thesis tests this hypothesis by applying a multi-proxy approach of coupled δ18O, Mg/Ca ratios and δ44/40Ca measurements on planktonic foraminifera in order to decouple the influence of sea surface temperatures (SST) and sea surface salinity (SSS) during the Termination on the individual proxy.
