The existence of groundwater in the Antarctic was suggested by seismic and field electrical studies. Groundwater in the area is thought to be a calcium-chloride type water. And the ground water collected in the drilled hole at L. Vanda, Victoria land in the Antarctic was highly saline and calcium-chloride type water. From the results of caliculation and isotopic studies, the water may be equillibrium with gypsum. As an example, the chemical compositions of groundwater were shown as follows: Na+8.75, K+1.08, Ca2+33.2, Mg2+10.5,Cl-108, SO24-0.25 in g/kg.
