pH of the melted glacial ice within individual glaciers varied between 7.1 and 7.4. The cation concentrations in glacial ice ranged from 5 to 340 mg kg-1 for sodium, from 20 to 310 mg kg- for potassium, and from 70 to 550 mg kg- for magnesium. The highest phosphorus content was determined in Kongsvegen glacier ice sample, 9 mg kg-1; otherwise the content was low, <1-3 mg kg-1. The Kjeldahl nitrogen content ranged from 3.45 to 7.1 mg L-1, whereas ammonium nitrogen content ranged from 0.8 to 1.57 mg L-1. The water activity of melted ice ranged between 0.95 and 0.98, indicating a salt concentration of less than 5% [Gunde-Cimerman et al., 2003; Sonjak et al., 2006; Butinar et al., 2007].
