内容記述 |
In Seymour Island free of ice cover were found many ice-wedges and ice-wedge casts. In order to clarify chemical characteristics of ice in ice-wedges, chemical analyses were done on ice samples from an ice-wedge. The concentrations and compositions of chemical species in the ice body vary in an unexpectedly wide range and are greatly different between the upper and lower parts, even from the same ice-wedge ice body. Its lower part shows very high concentrations of Na^+ nas SC_4^<2->, whereas its upper part shows high Ca^<2+> and SO_4^<2-> concentrations. Vertical profiles of the concentrations and compositions of chemical species are also very specific, especially in their tracing zigzag courses. These facts indicate the existence of unexpectcd but very interesting formation processes of the ice-wedge ice body. |
