Abstract:
Measurements of stable oxygen isotope analysis were performed on four to fifteen specimens of Globigerina bulloides (250–315 μm). These analyses were performed on an Isoprime 100 (Elementar) dual-inlet Isotope Ratio Mass Spectrometer (Elementar) at the Laboratoire des Sciences du Climat et de l'Environnement (LSCE, France). The results are expressed as δ18O vs V-PDB (in ‰) through calibration to international NBS standards.
