Douglass introduced these techniques to North American and European scientists, who then appropriated the procedure to date the occurrence of natural events and the ... Learn About Dendrochronology. Research at the Tree Ring Lab uses the process of dendrochronology, or tree ring dating. This process depends on the fact that certain living trees grow every year in a predictable way. When the tree is cored from the center of the trunk to the outside of its bark, this growth can be seen through annual growth rings. Thus the living tree-ring chronology was extended 253 years into the past (from 1769 CE to 1516 CE), allowing the dating of new historical materials that may arise in the future for this period ...There are plenty of tree-ring-width graphics comparing two or, usually, more anual tree-ring-width series; describing too how sutiable timbers are seeked for and eventually found (or not), the unexpected outcomes in terms of history of Irish oak forests and other surprises arising from dating of archeological timbers, the two-pass correlation ...Early History of Crossdating.
