(Figure 5) Oxygen and carbon isotope composition of Neogloboquadrina pachyderma sin. in near-surface sediments

Size fraction >62.5 µm. GC352, GC357, GC368, GC370, GC371, GC372 283 and GC374 were analysed with a Thermo-Finnigan MAT 253 mass spectrometer at the Godwin Laboratory for Palaeoclimate Research (Cambridge University, UK). Those from multiple core PS2543-3 were analysed with a Thermo-Finnigan MAT 251 mass spectrometer at AWI.

粒径大于62.5 µm的组分。针对GC352、GC357、GC368、GC370、GC371、GC372 283及GC374样品，于英国剑桥大学古气候研究戈德温实验室使用Thermo-Finnigan MAT 253型质谱仪完成了分析测试。取自多岩芯PS2543-3的样品，则在AWI使用Thermo-Finnigan MAT 251型质谱仪开展了分析测试。
