Electrical conductivity and pH in snow and ice samples from various glacier areas
Electrical conductivity (EC) and pH of melted snow and ice samples from Nepal, Patagonia, Arctic regions and Antarctica are compared. Most samples showed regional differences in means and ranges of EC and pH values. Low concentrations of dissolved substances, however, were accompanied by low ECs and...
