P
PYT0RJBEOLO.c. wuellerstorfi d13c +	1-10 specimens, 315-400 µm size fraction  +
PYT1ZK5FLCQ.u. peregrina d18o +	1-15 specimens, 315-400 µm size fraction  +
PYT263GUKAT.age14c +	For radiocarbon dating the surface-dwelling planktic foraminifera species Globigerinoides ruber in a strict sense and Globigerinoides sacculifer (without the sac-like final chamber) were handpicked under a binocular microscope from the >150 µm fraction. The abundance of these species within the cores was generally low, and occasionally, both species were combined to obtain a sufficient amount of datable material.  +
PYT3BFZK5EK.d18og +	isotope ratio mass spectrometry  +
PYT3L6BW4OB.d18og +	25-30 individual shells were pooled, sonicated for 5s in methanol, roasted at 375 degC for 30 min in vacuo and then reacted individually in 105% H3PO4 at 90degC  +
PYT4GF6APIN.d18ou +	60-100 shells were gently crushed open under glass slides. Samples were purified of organic matter with hydrogen peroxide, ultasonicated in acetone, dried at 50C  +
PYT56FXLTUB.g. bulloides d18o +	30-40 specimens picked from the 250-315μm size fraction. Measurements were conducted with a Thermo Scientific MAT253 IRMS coupled to a Kiel IV sample gas preparation device.  +
PYT5Z4BM1HD.g.inflata d13c +	about 20 specimens, 250-315 µm size fraction  +
PYT6T5QYQCK.gdgt-3 +	High Performance Liquid Chromatography - Mass spectrometry (HPLC-MS)  +
PYT7DGGKKES.sst +	ufuf  +
PYT7JD8Q23P.g. inflata d18o +	about 20 specimens, 250-315 µm size fraction  +
PYT7Z7JMLKT.mg +	asdfas  +
PYT80Q7P5ZU.age14c +	accelerated mass spectrometry  +
PYT8KNOASAM.mg/ca +	Cleaning include a reductive step. Accuracy of the data was checked by analyzing the carbonate reference standard ECRM 752-1  +
PYT8QRXXH0K.age14cuncertainty +	AMS  +
PYT953Q8LQ3.gdgt-5 reg-iso +	High Performance Liquid Chromatography - Mass spectrometry (HPLC-MS)  +
PYT9RQ8O0TX.labcode +	asdfasd  +
PYTBH59XDH0.d18og.rub +	Approximately 30 to 40 individual G. ruber (white variety) were picked from samples that had been washed through a 350um sieve with distilled water. The picked specimens were cleaned using the trace metal cleaning technique of Martin and Lea. Each automated batch of sample analyses includes a number of standard carbonates analyzed throughout the automated run. Sample results were adjusted for any internal drift of an automated run.  +
PYTCCBG1QL1.14c uncertainty +	asdfasd  +
PYTE66BFL9X.gdgt +	High Performance Liquid Chromatography - Mass spectrometry (HPLC-MS)  +
PYTES973TGM.sst.Calibration +	Bayesian  +
PYTFSXYJF6G.mg/ca +	300 micrograms of foraminiferal material. 250-355 micrometer size fraction  +
PYTG2PJGTRZ.calib14c +	Fairbanks 0107  +
PYTHO7UXES4.mg/ca-g.rub +	Approximately 30 to 40 individual G.ruber (white variety) were picked from samples that had been washed through a 250um sieve with distilled water. The picked specimens were then cleansed using the trace metal cleaning technique applied to marine carbonate sample of Martin and Lea. The method for determining the Mg/Ca in foraminifera follows the one described by Schrag, which involves a sequential analysis of a standard-sample-standard. Each sample Mg/Ca value is corrected based on the bracketed standard values.  +
