Abstract:
Dielectric Profiling (DEP) of the North Greenland Eemian (NEEM) core were recorded in the field during the 2008-2011field seasons with the DEP device described by Wilhelms et al. (1998). The permittivity and conductivity of DEP data are calculated by their respective densities and conductivities (Wilhelms, 2005). The resolution of DEP data is 5 mm. The DEP was not processed at a consistent temperature due to the varying temperature in the field seasons. The upper 100 m is measured on NEEM–2008–S1 core, which was the NEEM pilot core. For more information on the calibration procedure see Mojtabavi et al, 2020.
