Description:
dD (permill) measured on TALDICE ice core at 5 cm resolution between 1438 m depth and 1619 m depth associated with ice age defined by the TALDICE 1a chronology.
The dD measurements (permill) are performed between 1438 m depth until 1620 m depth at 5 cm and 10 cm resolution. Discrete samples at 10 cm-resolution between 1438 m and 1486 m depth are measured at the University of Venice using a Thermo Fisher Delta Plus Advantage mass spectrometer coupled with a HDO device. The precision of δD measurements is ± 0.7‰ (1σ). Below 1486 m depth, discrete 5 cm-resolution analyses are carried out the University of Venice and LSCE using the Cavity Ring Down Spectroscopy technique (CRDS). Analysis are performed using a Picarro isotope water analyser (L2130-i version) for both laboratories. The data are calibrated using a linear calibration with three lab-standards periodically calibrated vs V-SMOW.
