Mg/Ca ratio, stable isotopes and sub-surface temperatures derived from benthic foraminifers in core GEOFAR KF16 and MD08-3180

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
