Cross-dating is considered one of the most important principles of dendrochronology. The first known cross-dating attempts, conducted between the years 1737 and 1783 by independent researchers in France, Germany, and Sweden, were related to the identification of growth rings believed to have formed ...

A significant part of our cultural heritage consists of wood. Research on historical wooden structures and artefacts thereby provides knowledge of people's daily lives and the society in which they lived. Dendrochronology is a well-established dating method of wood that can also provide valuable...

Bulk wood density measurements are recognized for their utility in ecology, industry, and biomass estimations. In tree-ring research, microdensitometric techniques are widely used, but their ability to determine the correct central tendency has been questioned. Though rarely used, it may be...

Dendrochronology is a well-established dating method for wooden objects, but due to surface processing of construction timber or natural degradation the dating of historical wood often relies on a prediction of the number of missing rings based on sapwood statistics. Since Scots pine (Pinus...

The Royal flagship Gribshunden carried the Danish King Hans on its way to the city of Kalmar in Sweden when the ship sank in the summer of 1495. The ship caught fire while anchored north of the Stora Ekö Island and sank to the seafloor, where it lies to this day. The wreck was rediscovered in the...

To assess past climate variability in west-central Scandinavia, a new 972-year-long temperature reconstruction, based on adjusted delta blue intensity (ΔBI_adj), was created. Presently, it is the longest blue intensity chronology in Fennoscandia and the third longest in the northern hemisphere....

Increment cores with intact tree rings are crucial in dendrochronological investigations to age trees. However, it is not always possible to obtain complete cores from trees because of rot, so alternative methods need to be explored. We tested the collection of one oblique core and one straight...

It is often argued that the repetitive removal of branches to improve the quantity and the quality of wood, i.e. woodland management, has been practiced in Europe from the Mesolithic and/or Neolithic onwards. The Neolithic pile dwelling of Alvastra in Sweden has been mentioned in textbooks as a...

Despite the spatially homogenous summer temperature pattern in Fennoscandia, there are large spreads among the many existing reconstructions, resulting in an uncertainty in the timing and amplitude of past changes. Also, there has been a general bias towards northernmost Fennoscandia. In an attempt ...

Tree-ring maximum latewood density (MXD) records from Fennoscandia have been widely used to infer regional- and hemispheric-scale mean temperature variability. Here, we explore if MXD records can also be used to infer past variability of summer temperature extremes across Fennoscandia. The first...
