Five to twenty specimens of Globigerina bulloides between 300 and 500 μm were hand-picked for oxygen isotope analyses. Specimens were washed with ethanol, ultrasonicated for several seconds and dried for 24 hours to eliminate all liquids. Samples were analyzed at Kiel University with a MAT 253 mass spectrometer connected to a Kiel IV carbonate preparation device. The analytical precision of international and laboratory-internal carbonate standards was better than ±0.05 ‰ (δC) and ± 0.08‰ (δO).
