Oxygen and carbon isotopes were measured for several planktonic foraminifera species (Globigerina bulloides, Neogloboquadrina pachyderma sinistral (sin.), Globoconella spp.) and the benthic foraminifera genus Cibicidoides spp. in samples from Ocean Drilling Program (ODP) Site 1088B. Typically, 10-15 planktonic specimen and five benthic specimen larger than 150μm were picked per sample. Foraminifera were crushed, rinsed twice with deionized water and once with MeOH and dried overnight at 50°C. Samples were analyzed at ETH Zurich on a GAS BENCH II system coupled to a Delta V Plus irMS (Thermo Scientific) following procedures described by Breitenbach and Bernasconi (2011). Analytical precision after system calibration by two in-house standards and international standards NBS-19 and NBS-18 was 0.07‰ for both stable isotopes. Values are reported relative to the VPDB standard.Different alkenone ratios (U_37^k' and C37.2/C38.2) were directly estimated with a Thermo Scientific Trace 1310 Gas Chromatograph (GC) ...
