| Abstract: | Ice crystals were measured from a marginal ice core from East Antarctica. The climatic significance related to ice crystals was discussed. A comparison was made between the Dunde ice core results and other ice core results. Based on the changes of ice crystals along the depth and the ubrupt changes of ice crystals during the Last Ice Age, it was concluded that climate can not only affect the growth rate of ice crystals, but also affect ice crystal size under specific climatic condition (e. g. Last Ice Age). The fact that climatic information can be reserved in marginal ice of ice sheet indicates that the conclusion that ice crystal growth rate can be influenced by ice surface temperature memory also applied to marginal ice of ice sheet. |
