Dendrochronology cross dating
Citations were used correctly, and there was nothing in the article that seemed "off" or made me really question its validity. "Temperature Changes On The Tibetan Plateau During The Past 600 Years Inferred From Ice Cores And Tree Rings." Global & Planetary Change 69.1/2 (2009): 71-78. I think the important thing to bear in mind is that dendro, like many other incremental dating techniques, can often lack precision (relatively) but still yield accurate results.In some ways the precision : accuracy relationship here is opposite to that of C14 dating (i.e.- MPF , (UTC)No problem on the second; although wood is of course only produced by a tree while still alive, once dead, the old wood remains available for study until such time as it decays away.In the case of Great Basin Bristlecone Pines studied by Ferguson, this is a very long time; he found trees that had been dead for several thousand years and was still able to study the growing conditions they had been alive in.
MMc Annis, Yuma AZ Unless I didn't understand it, it seems a self evident tautology with little relevance to the paragraph.This article is within the scope of Wiki Project Archaeology, a collaborative effort to improve the coverage of Archaeology on Wikipedia.If you would like to participate, please visit the project page, where you can join the discussion and see a list of open tasks.In terms of discussing dendrochronology as a paleoclimate proxy, this article needs a lot of work. This article in particular is what I would have modeled the Wikipedia article after.While it contains a lot of good information about the theory behind why and how tree rings work as a proxy, it doesn't explain the calibration well. It gives a detailed analysis of dendrochronology's applications to climatology as a proxy.
