High-resolution stable oxygen isotope and Mg/Ca analyses on benthic foraminifera spanning 25.95-25.78 Ma from IODP Site 342-U1406


This dataset lists the results of stable oxygen isotope measurements (in ‰ VPDB) , and trace element analysis (Mg/Ca ratios in mmol mol-1) 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 ~4-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.
