Planktic foraminifera oxygen isotopes and trace metals, and sortable silt data of sediment core KNR197-10-44GGC

Dataset

DOI

This dataset comprises paleoceanographic reconstructions from KNR197-10-44GGC using multiple proxies, including coarse fraction percentage; ice rafted detritus counts; planktonic foraminifera abundance (shown as % Neogloboquadrina pachyderma); sortable silt grain size data (analysed on both a Beckman Coulter Multisizer 4 using the Enhanced Performance Multisizer 4 beaker and stirrer setting 30 for full sediment suspension and a Malvern Mastersizer 2000 at University College London) and inferred flow speed; foraminiferal d18O (planktonic foraminifera: Neogloboquadrina pachyderma and Globigerina bulloides; benthic foraminifera: Globobulimina affinis and Nonionellina labradorica) measured on a VG Isogas SIRA mass spectrometer with the MultiCarb preparation system (for sample size > 80 µg) and a Thermo MAT253 isotope ratio mass spectrometer with Kiel IV carbonate preparation device (for sample size 5 µg post-cleaning weights were analysed for a suite of trace metal elemental ratios at the ICP-MS Trace Metal Lab at the University of Colorado, Boulder.
