Dendrochronology cross dating


Dendrochronology, the study of the annual growth in trees, is the only method of paleoenvironmental research that produces proxy data of consistently annual resolution.Initially the cells are thin walled to conduct the abundant spring soil moisture.Carbon-14 is a naturally occurring isotope of the element carbon.In seasonal climates, trees preserve a continuous record of annual events, in particular, climate.It does discuss the relative time-span the proxy covers, but it doesn't discuss other pros/cons. Anth1112 (talk) , 22 February 2017 (UTC) Do you mean "annual rings"? -phma The growth ring is the annular region consisting of the earlywood and the subsequent latewood, moving away from the wood center (pith).One question I had when I finished reading the article was, "How does this proxy compare to others? From AN INTERACTIVE IMAGE ANALYSIS SYSTEM FOR DENDROCHRONOLOGY by Giribalan Gopalan(talk) , Jclerman (talk) , 9 November 2008 (UTC)9 November 2008 (UTC) The Google polling approach is not scholar-wise.



As far as assumptions go, I couldn't really find much about this. Wdanwatts , (UTC)Surely this is all depends on what's being counted and how. Without knowing that, it's not possible to say that years with '0' values are included to aid comparison and correlation.In 1901, he noticed ring-width variations on a cut log and reasoned that these were controlled by the tree's environment (Fritts, 1976).Douglass (1920) illustrated the relationship between climate and ring width by plotting both against time, and introduced the technique of cross dating by correlating ring-width signatures (sequences of wide and narrow rings) among trees distributed over large areas.After reading, I understand better the concept of tree rings and some of the finer details that complicate the issue (such as alternating poor/favorable conditions and "missing rings"), but I don't understand all of the applications to understanding past climates. Please feel free to edit the article to make these points clear.

The sources used in the article are mostly peer-reviewed and seem relevant for the most part. Jclerman (talk) , 9 November 2008 (UTC) How does dendrochronolgy correlate with C14 dating?

Cronin's textbook mentions that calibration is one of the most important aspects of using proxies, and it is only briefly mentioned in the article. To improve this article, I would have broadened its scope.
