abstract
Background and Aims: Disentangling tree growth requires more than ring width data only. Densitometry is considered a valuable proxy, yet laborious wood sample preparation and lack of dedicated software limit the widespread use of density profiling for tree-ring analysis. We present an X-ray computed tomography-based toolchain of tree increment cores, resulting in profile datasets suitable for visual exploration as well as density-based pattern matching. Methods: Two temperate (Quercus petraea, Fagus sylvatica) and one tropical species (Terminalia superba) were used for density profiling using an X-ray computed tomography facility with custom-made sample holders and dedicated processing software. Key results: Density-based pattern matching is developed and able to formally detect anomalies in ring series that can be corrected via interactive software. Conclusions: A digital workflow allows to generate structure corrected profiles of large sets of cores in a short time span that provide sufficient intra-annual density information for tree-ring analysis. Furthermore, visual exploration of such datasets is of high value. The dated profiles can be used for high-resolution chronologies and also offer opportunities for fast screening of lesser studied tropical tree species.
