= word = the science of): 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.
The science that uses tree rings to date when timber was felled, transported, processed, or used for construction or wooden artifacts.
The process that removes undesirable long-term variations from a time series of measured tree-ring properties by dividing the actual measurements by those predicted from a statistically derived equation that relates tree growth over time to tree age.
Usually this process tries to remove the growth trends due to normal physiological aging processes and changes in the surrounding forest community.
In fact, the introduction of "divergence" into the dendro-lexicon in the late 1990s epitomized the changing response of trees to climate over time, first scrutinized in detail in the mid-1980s. Perhaps it actually "Paradoxically, in suggesting that this term now be dropped from use, we pay a most fitting tribute to its vital role in the history of geology." -- Stephen Jay Gould, 1965, "Is uniformitarianism necessary"?
This principle states that matching patterns in ring widths or other ring characteristics (such as ring density patterns) among several tree-ring series allows the identification of the exact calendar (or relative) year in which each tree ring was formed.
NOTE TO READERS You may notice that the principles below represent a major change in the way we approach dendrochronology.
This is because, as a scientific discipline evolves, so too must the principles to which it adheres. I kept adding new principles while simultaneously revising or even deleting long familiar principles.
For example, an index of 0.75 (or 75) for a given year indicates growth below normal (indicated by 1.00, or 100).Example: analyzing ring widths of trees to determine how much rainfall fell per year long before weather records were kept.The science that uses tree rings to study factors that affect the earth's ecosystems.I'm sure, over time, we may find that one or more principles below are not really needed or that new principles need to be introduced. This principle was most applied to reconstructions of past climate, assuming that the climate response seen in trees during modern times was the same as the climate response in trees during previous times.Study after study has now shown this not to be the case.
