Stable oxygen and carbon isotope ratios measured on groups of four shells of Neogloboquadrina pachyderma from Irminger Sea sediment trap time series

Stable oxygen and carbon isotope ratios measured on groups of four shells of Neogloboquadrina pachyderma from a sediment trap time series from the central Irminger Sea. Measurements were made on groups of four shells in the 150-250 μm fraction using a Finnigan MAT253 coupled to a Kiel IV preparation line. Sample averages have been reported doi:10.1594/PANGAEA.753860 (d18O) and doi:10.1594/PANGAEA.807458 (d13C). Repeat measurements of a carbonate standard indicate an analytical precision of 0.05 and 0.03 permille for d18O and d13C, respectively. Details on the measurements and the sediment trap mooring can be found in doi:10.1029/2009PA001849 and doi:10.1002/palo.20018.
