Results of isotopic analysis of planktonic foraminifera from sediment core 189 of the Swedish Deep-Sea Expedition (Table I)
For temperature investigations, a core in the Mediterranean Sea (No 189 of the Swedish Deep-Sea Expedition 1947-1948) was sampled at approximately 10 m intervals. Globigerina dubia, G. inflata and Globigerinoides rubra were seperated from each sample and their test were investigated for stable oxyge...
