4. Elemental variability in tree-rings as indicator for climate change : a case study on beech and oak trees at the Laacher See, Germany
Master-uppsats, Stockholms universitet/Institutionen för naturgeografiSammanfattning : The aim of this study was to contribute to the comprehension of the connection of element uptake in trees at the Laacher See in Germany and climatic parameters on different time scales. Understanding the relationship of certain elements in trees and temperature might enable the assignment of extraordinary high peaks in the elemental concentration, which cannot be explained by temperature, to another process as CO2 degassing of the mofettes, which are relics of the volcanic past of the lake.
