Concentration of hydrogen ions measured with the Electrical Conductivity Method (ECM) on the NGRIP ice core ...
The ECM data has been temperature corrected to a standard temperature of -14 °C, according to an Arrhenius relationship using an activation energy of 0.23 eV. Subsequently, the measured current has been converted to ice acidity using the relationship suggested by Hammer (1980). For more information...
