Outline of Final Research Achievements

In this study, the formation process of varved sediments and the definition of lamina as a varve in Lake Mokoto and Lake Abashiri in Hokkaido were established. We analyzed the detailed characteristics of recent flood events and discussed the issue of sediment runoff. Based on that, it was clarified that some past flood events can be used as a key bed. The varved ages were counted in the late Holocene, and sediment flux and organic carbon flux are estimated. From the results, we could presume the artificial and natural environmental changes in the lake and its basin. By analyzing the detailed varve sediments in the lake Mokoto, cyclic climate events such as 11-year climate change corresponding to the sunspot cycle were revealed.

Academic Significance and Societal Importance of the Research Achievements

年縞堆積物の形成過程は,過去の環境変化を考えるために重要なものであるが,それに伴って現在の問題にも関係している.本研究では,藻琴湖,網走湖の現在の環境と近年の変化を明らかにした.それにより近年の降水量の増加や可動堰の建設から湖沼環境が変化したが,2湖沼で対照的であることが明らかとなった.過去の降水量の復元から,降水量の周期性はまだ認められていないが,近年の降水量の増加はそれとは異なる特性でないかと思われる.しかし,黒点周期に対応する11年周期気候変化などの周期イベントが明らかとなろ,さらに解析すれば新しい周期気象現象を見いだせる可能性が高い.このレベルの解析は年縞堆積物のみ可能である.
