A 133 m deep Antarctic ice core from Dolleman Island, Antarctic Peninsula, has been profiled by dielectric measurements in the AF‐LF (20 Hz ‐ 100 kHz) frequency range. This has revealed large variations in dielectric relaxation and conductivity down the core. A comparison with the chemical stratigra...
