Interlaboratory Comparison of Water Isotope Measurements: Continuous Flow Analysis and Discrete Data from an Ice Core Section

Continuous water isotope measurements obtained from a common 4-meter section (12-16 m depth) of an Antarctic firn core, analyzed using Continuous Flow Analysis (CFA) systems coupled with Cavity Ring-Down Spectrometers three different laboratories: Ca’ Foscari University of Venice, the Laboratoire des Sciences du Climat et de l’Environnement (LSCE) in Paris, and the Institut des Géosciences de l’Environnement (IGE) in Grenoble. We additionally provide discrete samples analyzed offline at the Venice laboratory.
