Abstract:
This dataset lists the results of stable oxygen isotope measurements (in ‰ VPDB) and trace element analysis (Mg/Ca ratios in mmol mol-1) on benthic and planktic foraminifera as well as the coarse fraction (in %) from International Ocean Discovery Program (IODP) Site U1406 off Newfoundland (~40°N, 51°W; 3814 m water depth, Expedition 342, NW Atlantic Ocean) for a ~30-m-long interval of the splice record. Stable isotopes were analyzed using a ThermoFinnigan MAT253Plus gas source mass spectrometer equipped with a Thermo Fisher Scientific KIEL IV carbonate device. Values are reported relative to the VPDB through the analysis of an in-house standard (Solnhofen limestone) calibrated to IAEA-603. Mg/Ca ratios were analyzed using a Agilent Inductively Coupled Plasma-Optical Emission Spectrometer (ICP-OES) 720. Mg/Ca data was normalised relative to the ECRM752-1 standard.
