Specific conductivity measured with the dielectric profiling (DEP) technique on the NGRIP ice core

DOI

The dielectrical stratigraphy of the NGRIP core was recorded in the field with the dielectric profiling (DEP) technique (Wilhelms et al., 1998). Ice core sections of 1.65 m were usually analysed no more than one day after drilling. Due to missing measurements of the cable stray capacitance and conductance, the data has not been corrected for cable stray conductance, and the dataset still contains a periodic variation with amplitude of up to 2% of the baseline conductivity and a wavelength of 1.65 m.The DEP data sets is provided in processed form without correction for the temperature variation in the science trench or in the core-buffer. Therefore, care should be taken when interpreting the absolute levels between sections.
