Abstract:
Deglacial stable oxygen and carbon isotope data and Mg/Ca BWT data from benthic epifaunal foraminifera species C. wuellerstorfi and infaunal species Melonis affinis and Melonis barleanum from parallel cores GEOFAR KF16 and MD08-3180, in the central subtropical North Atlantic.
Stable isotope data measured at Leibniz Laboratory for Radiometric Dating and Stable Isotope Research in Kiel using a Finnigan MAT 253 mass spectrometer coupled with a Kiel IV carbonate preparation device and calibrated to the V-PDB scale.
Analytic error for stable isotope measurements: > 0.1 per mil for δ18O and >0.05 per mil for δ13C,
Mg/Ca cleaning was carried out following the protocol of Martin and Lea (2002) including reductive and oxidative cleaning step
Mg/Ca were measured in a simultaneous ICPM-OES instrument with radial plasma observation at the IfG Kiel.
Analytical error for Mg/Ca analyses (monitored with ECRM-752): 0.1% RSD
