Definition

The acidity of glacier ice is the degree of acidity (content of [H+]) of glacier ice, reflecting the dissolved anionic contents among the grain boundaries of glacier ice.

Acidity of glacier ice

The acidity of glacial ice is determined by the anionic contents of aerosols captured by snow and ice. When no extra ions are in input, then ionic balance in current polar snow/ice can be represented as:
$$\eqalign{\Delta {\text{C}} = \ [{\text{N}}{{\text{a}}^{+} }] + [{\text{NH}}_4{^+} ] + [{{\text{K}}^{+} }] + [{{\text{H}}^{+} }] + [{\text{C}}{{\text{a}}^{2 + }}] \cr + [{\text{M}}{{\text{g}}^{2 + }}] - [{{\text{F}}^{-} }] - [{\text{C}}{{\text{l}}^{-} }] - [{\text{NO}}_3{^-} ] - [{\text{SO}}_4{^2}{^-} ] \cr - [{\text{C}}{{\text{H}}_3}{\text{SO}}_3{^-} ] - [{\text{HCO}}{{\text{O}}^{-} }] - [{\text{C}}{{\text{H}}_3}{\text{CO}}{{\text{O}}^{-} }] }$$
