Outline of Final Research Achievements

The Suigetsu varve chronology (i.e. the age model based on the counting of annual and seasonal laminations) was extended to the varve limit at 40.4 m core depth and the exact depth of the varve limit was reliably determined for the first time.A significantly improved varve interpolation programme was developed. In difference to the first attempt to develop such a tool for incompletely varve records (such as Lake Suigetsu) the programme can now be run fully automated and can be applied to a much wider range of archives due to the new approach of probability distribution fitting.
Alongside varve counting also high resolution microfacies data were collected. These were and are used for palaeo-environmental reconstruction, such as the climate evolution at the end of the last glaciation and high resolution flood/typhoon reconstruction for the last glacial.The data are currently used for further palaeo-environmental analysis and prepared for forthcoming publications on geochronology.
