| 内容記述 | The field expeditions in Eastern Siberian Permafrost was conducted in both 1995 and 1996 as to get detail information of the permafrost response to climate change. In the low land area of Kolyma River, there exist the unique deposit of permafrost with large ground ice accumulation, which is locally "Edoma or Ice Complex". The genesis and occurrence of Edmoa reflect the long term climate change at high arctic Siberia. Because of the active response of Permafrost under present climate warming trend, it is important to understand the process of accumulation of Edmoa. Present authors sampled the organic materials from Edoma at various locations in these regions. Edoma tends to thaw in large scale after the Last Glacial Periods. By thawing and melting of ground ice, ground surface subsides and results in formation of Thermo-Karst depression, which is locally names as Alas. ^<14> dating results indicated the thawing of Edoma started at about 8000yBP ago and continued until about 4000yBP. As lowest boundary of Edoma was not detected, the initiation period of Edoma was not estimated yet. However at three locations in low land Kolyma, organic materials including fossil of Mammal were dated as the time of Karginsky Interstadial and Sartan Stadial in Last Glacial. Edoma in this region was categorized into two groups. Edoma along the coast of arctic sea near river mouth of Kolyma, named as Ambarchik started its accumulation in karginsky Interstadial and terminated its accumulation at the late karginsky Interstadial. On the other hand, two sites along Kolyma River, Plaxina Yar and Krasivoe, results of dating suggested accumulation of Edoma might continued in the middle of Sartan Stadial. These dated values newly imply Edoma in this region is the most latest accumulation in Eastern Siberian Permafrost. | |||||
