Research project To understand climate variation over long time periods, lake sediment records may be used. We will develop statistical tools that can analyse several thousand years old varved lake sediments with respect to climate change.
Climate and environmental changes are today widely discussed, and in particular the impact of human activity. To understand variations in the climate over longer time periods, historical documents, year rings from trees, ice cores from glaciers as well as lake and sea sediments are being used. In this project, we develop statistical models and tools to analyse varved lake sediments. The tools aim at understanding the natural variation in the climate and the environment, and are developed based on a 6000 years old time series from the lake Kassjön.
