Stable isotope ratios were obtained at the stable isotope laboratory at Department of Earth Sciences and the Bjerknes Centre for Climate Research at the University of Bergen, using Nier type (gas source) mass spectrometers. Analyses of N. pachyderma (sin) were carried out on a Finnegan MAT251 mass spectrometer from 0-15.5 cm in the core. All planktonic samples were run in four replicates. The stable isotope results are expressed as the average of the replicates and reported relative to Vienna Pee Dee Belemnite (VPDB), calibrated using NBS-19 Long-term analytical precision (1 sigma) of the standards over a time interval of several months is <0.08 per mil for for the MAT251 system. ...
