All data are free of krypton interference during the mass spectrometric analysis. dD(CH4) data are measured using the system described in:Bock, M., J. Schmitt, J. Beck, R. Schneider, H. Fischer, "Improving accuracy and precision of ice core dD(CH4) analyses using methane pre-pyrolysis and hydrogen post-pyrolysis trapping and subsequent chromatographic separation", Atmospheric Measurement Techniques, 7, 1999-2012, 2014, doi:10.5194/amt-7-1999-2014 ...
