Abstract:

For stable O and C isotopes analysis, 25 planktonic and 10 benthic foraminifera of the species Globigerina bulloides and Cibicides pachyderma were picked primarily in the fraction >250 μm, and occasionally in the interval 150–250 μm, in 113 samples, at the IGME. The analyses were performed in a Finnigan MAT 252 mass spectrometer at Marum (University Bremen, Germany), coupled to an automated Kiel-carbonate preparation system. The long-term precision is ±0.07‰ for δ18O and ±0.05‰ for δ13C based on repeated analyses of internal and external (NBS-19) carbonate standards. The stable O and C ratios are expressed as δ in permil (‰), relative to Vienna Peedee Belemnite (VPDB) standard. Nine duplicated samples in TG2 give a standard deviation between 0.07 and 0.12‰.
