A significant part of our cultural heritage consists wood. Research on historical wooden structures and artefacts thereby provides knowledge people’s daily lives the society in which they lived. Dendrochronology is a well-established dating method wood that can also provide valuable about climate dynamics, environmental changes, silviculture, transformations. However, dendrochronology comes wit...

The Bremen-Cog was dated by dendrochronology in the 1960s when discipline its infancy. felling date of winter 1378/79 Weser Uplands established and confirmed 2007. In 2016 a new comprehensive analysis ship made possible. All analysed samples are from trees likely felled last quarter 14th century direct hinterlands Bremen. Furthermore, an attempt at tree morphology reconstruction detailed invest...

Vessels and tracheids represent the most important xylem cells with respect to long distance water transport in plants. Wood anatomical studies frequently provide several quantitative details of these cells, such as vessel diameter, vessel density, vessel element length, and tracheid length, while important information on the three dimensional structure of the hydraulic network is not considere...

Dendrochronology is the science that uses tree-rings dated to their exact year of formation to analyze temporal and spatial patterns of processes in the physical and cultural sciences. There currently is no published record for tree-ring studies using Eastern Red Cedar in the Upper Mississippi River Valley in Wisconsin. Therefore, this study develops a chronology from treerings using Eastern Re...

This paper illustrates how archaeomagnetic dating can be used for palaeochannel fills within floodplain sequences. The sites investigated are palaeochannels associated with the mediaeval braided/anastomosing channels of an unstable reach of the River Trent at Hemington, north-west Leicestershire. This reach has revealed abundant archaeological remains including fish weirs, anchor stones, a Norm...

In dendrochronology wood samples are dated according to the tree rings they contain. The dating process consists of comparing the sequence of tree ring widths in the sample to a dated master sequence. Assuming that a tree forms exactly one ring per year a simple sliding algorithm solves this matching task. But sometimes a tree produces no ring or even two rings in a year. If a sample sequence c...

The astronomer A.E. Douglass is generally recognized as the founding father of dendrochronology. He studied tree rings in the search for evidence that solar variation (as seen in sunspots) is reflected in climate variation. He was convinced that his quest was successful. Analysis of some of his early data using Fourier decomposition and comparison of tree-ring periodograms with those based on k...

We investigated an old-growth oak-shortleaf pine (Pinus echinata) stand of high ecological integrity in east-central Oklahoma located west of the continuous native distribution of shortleaf pine. With the exception of an abundance of shortleaf pine, the basal area (17.2 m/ha), density (559.6 trees/ha), and species composition of this unmanaged stand is similar to other old hardwood forests in t...
