It is originated in the subpolar maritime climate which is characterized by higher mean annual temperature with cooler summer and abundant precipitation in uniform yearly distribution. It is found that the ice formation is mainly processed through warm infiltration having superimposed ice on some surface: the glacier has higher temperature while colder ice is discovered in a certain area. the ice moves in lower speed while its base is in sliding. So the ice cap is attributed to the subpolar maritime glacier by the authors. In spite of being in stable state during the last 20 years the mass balance of the ice cap behaves positive in recent 10 years due to the increase of precipitation, which offsets the effect of raising air temperature.展开更多
