This method is of particular importance to our study of the human past, when analysing shipwrecks, barrels, painted panels and artistic or eccliastical sculpture, as these particular objects were widely transported and traded.
However, analysing the region of origin of timber from structures on land is also showing us the extent of traded timber through time.
Dendrochronological cross-dating against the master chronology showed that the rings of the panel represent the period 1413–1620.
These two methods produced comparable tree ring series.
The lens- and photography-based records of the measured panel exhibited higher agreement with each other than the conventional, lens-based, record against the different master chronologies.
Some regions in Northern Europe at various times over-exhausted their native timber ressource, and needed to import timber from regions that had surplus.
Using my provenance determination technique the chronology, geography and extent of the trade in building timber in Northern Europe is increasingly emerging.
The outermost ring records the year that the tree was felled.
Dendrochronology, or 'tree ring dating' as it is often known, can provide an invaluable insight into the history of a building by revealing the year in which the timbers used in its construction were felled.
Dendrochronology or tree-ring dating is the method by which timbers are precisely dated through measurement and analysis of the trees’ ring width.
The variation in the tree-ring width, influenced by the annual climate variation during the trees’ growth, is the code used in dendrochronology.
But for the specimen to be useful in extending the tree-ring chronology, the absolute calendar age of its rings must be determined.
The annual growth rings vary in thickness each year depending on environmental factors such as rainfall.
By matching ring-width patterns in a specimen of known age (starting with living specimens) to ring-width patterns in an older specimen, the proper placement of the older specimen is determined.
