Tree ring dating worksheet


I present a new software that links a program for image analysis (Sigma Scan), one for spreadsheets (Excel) and one for statistical analysis (R) for applications of tree-ring analysis.The first macro measures ring width marked by the user on scanned images, stores raw and detrended data in Excel and calculates the distance to the pith and inter-series correlations.A second macro measures darkness along a defined path to identify latewood–earlywood transition in conifers, and a third shows the potential for automatic detection of boundaries.Written in Visual Basic for Applications, the code makes use of the advantages of existing programs and is consequently very economic and relatively simple to adjust to the requirements of specific projects or to expand making use of already available code.) of the White Mountains of Eastern California, were dated in 1957 by counting tree rings at 4,723 years old.This would mean they pre-dated the Flood which occurred around 4,350 years ago, taking a straightforward approach to Biblical chronology.However, when the interpretation of scientific data contradicts the true history of the world as revealed in the Bible, then it’s the interpretation of the data that is at fault.

As a tree physiologist I would say that evidence of false rings in surely counts much more strongly against such the notion. Considering that the immediate post-Flood world would have been wetter with less contrasting seasons until the Ice Age waned (see Q&A: Ice Age), many extra growth rings would have been produced in the Bristlecone pines (even though extra rings are not produced today because of the seasonal extremes).Creationists have shown that the biblical kind is usually larger than the ‘species’ and in many cases even larger than the ’genus’—see my article Ligers and wholphins? Taking this into account would bring the age of the oldest living Bristlecone Pine into the post-Flood era.Claimed older tree ring chronologies depend on the cross-matching of tree ring patterns of pieces of dead wood found near living trees.This procedure depends on temporal placement of fragments of wood using carbon-14 (C age and that also extends to a younger age.
