In the southern Spitsbergen area, thermal and mineral waters are primarily
associated with subpermafrost deep circulation, being mixed with shallow circulation and
glacial waters. Four thermal springs, located in the region of Stormbukta (Sørkappland),
were studied and analyzed. In the thermal waters, the main cation is sodium, while the
main anions are chloride and bicarbonate. The temperatures of the mineral and thermal
waters range from 3.4 to 15.1°C. The pH values are between 7.43 and 8.41. The total
dissolved solids (TDS) content of the geothermal waters is in the range of 346–4031 mg/l
and the Olsok thermal spring has the highest TDS values. Based on the variation in
physicochemical characteristics, two thermal water types were distinguished in the study
area. The first type is associated with thermal waters originating from deep circulation
waters. The second type is associated with the thermal and mineral waters originating
from the mixture of subpermfrost hot brines with glacial waters.
