Entwicklung 1000-jähriger Dichtechronologien für Ost- und Südeuropa
Zusammenfassung der Projektergebnisse
We sampled several hundred core and disc samples of living and relict larch and pine trees in the Tatra and Pindus Mountains in eastern and southern Europe. The samples were processed for TRW and MXD measurements, age trends were removed using stateof-the art detrending techniques, and chronologies produced to emphasize common variance and trends. Climate signals were assessed through calibration against regional instrumental data, and formal reconstructions produced using scaling and regression techniques. We produced a number of scientific publications including five papers on the work in the Pindus Mountains, one paper on the work in the Tatra, and three larger scale analyses in which the newly developed data were used to address research questions related to dating accuracy and historical recruitment dynamics. The new temperature reconstruction from the Pindus Mountains sets a benchmark for high-resolution paleoclimate records in the Mediterranean. Our reports on the oldest dendrochronologically tree in Europe, a 1075-year old Bosnian pine from northern Greece (“Adonis”), has been picked up by many news outlets (e.g. CNN).
