Under the direction of Dr. Jeffrey Dean, Mr. Stephen Nash will collect data for his doctoral dissertation. He will examine the archives and unpublished documents of a number of scientists who helped to found and expand the technique of tree ring dating and will analyze sample lists from laboratories which pioneered this approach. He wishes to understand how the development of dendrochronology affected the practice of archaeology in the United States and also how archaeology itself served to guide the direction the technique took. Until the 1920s, archaeologists in the United States had no means to date prehistoric events and chronologies were all relative rather than absolute. Tree ring dating provided the first of the many techniques now employed which can assign absolute dates. It was first developed in the Southwestern United States and is now widely used in this region. Because dendrochronology is based on the analysis of variation in the thickness of annual tree rings which in turn are dependent on local climatic events, chronologies must be developed independently from region to region. What Mr. Nash notes is that early in its history, researchers worked in a number of areas as far afield as Alaska to establish tree ring chronologies. Ultimately however all were abandoned and it is only in the Southwestern U.S. where the technique took hold. Mr. Nash wishes to examine this process and understand why different outcomes emerged. This research is important for several reasons. Archaeology is heavily technique dependent and is driven, in significant measure, by the development of new analytic techniques. The results of Mr. Nash's study will extend well beyond tree ring dating itself. The project will also assist in the training of a promising young scientist.

在Jeffrey Dean博士的指导下，Stephen Nash先生将为他的博士论文收集数据。他将研究档案和一些科学家的未发表的文件，这些科学家帮助发现和扩展了树木年轮测年技术，并将分析开创这种方法的实验室的样本清单。他希望了解树木年代学的发展如何影响美国的考古学实践，以及考古学本身如何指导该技术的发展方向。 直到20世纪20年代，美国的考古学家还没有办法确定史前事件的年代，年表都是相对的，而不是绝对的。树木年轮测年法是目前使用的许多确定绝对年代的技术中的第一种。它首先在美国西南部开发，现在在该地区广泛使用。由于树木年轮学是基于对树木年轮厚度变化的分析，而年轮厚度变化又取决于当地的气候事件，因此年表必须独立于各个地区。纳什先生指出，在历史的早期，研究人员曾在阿拉斯加等一些遥远的地区工作，以建立树木年轮年表。然而，最终所有人都被抛弃了，只有在美国西南部，这项技术才得以扎根。纳什先生希望研究这一过程，并了解为什么会出现不同的结果。 这项研究之所以重要，有几个原因。考古学在很大程度上依赖于技术，并在很大程度上受到新分析技术发展的推动。纳什先生的研究结果将远远超出树木年轮测年本身。该项目还将协助培训一名有前途的青年科学家。
