Acidity measured with the Electrical Conductivity Method (ECM) on the EGRIP ice core (down to 1383.84 m depth), converted to hydrogen ion concentration
ECM data of the East GReenland Ice core Project (EGRIP) core with the technique described by Hammer (1980) was recorded in the field during the 2017, 2018 and 2019 field seasons. The resolution of ECM data is 1 mm. The data is given as H+ ion concentration, but the absolute calibration must be considered tentative.
