Palaeo Climate

The analysis of past climate and environment variability has a strong focus on a combination of various archives as lake and reservoir sediments, kettle holes, peat bogs, soils and tree-rings in order to (1) provide a wide range of proxy data that cover all compartments and aspects of landscape change and (2) transforming point-scale information into a regional-scale context. Another important aspect is the link of the obtained information from the past with modern instrumental observation data provided by the other CTs within TERENO enabling calibrated palaeoclimate reconstructions at an unprecedented level of detail and temporal accuracy.


In addition to a broad range of proxy data (geochemical, geophysical, sedimentological, and biological) applied the combination of different geo-archives necessitates particular dating efforts. We will utilize a multiple dating approach including all state-of-the-art incremental and radiometric techniques. Backbone of these chronologies will be annual layer counts of tree rings and annual laminations in lake sediments because accurate calendar year time scales are essential. This concept allows proving data of past changes on comparable time scales as modern instrumental data. The link of instrumental and proxy data will be achieved by connecting remote sensing, automated observation systems with regular discrete sampling and sophisticated devices to recover long palaeo-records.
