Niagara Escarpment Tree-Ring Project

这项提议寻求对生长在加拿大尼亚加拉悬崖上的长寿针叶树北方白柏的树种年代学研究的支持。加拿大科学家之前的研究得出了安大略省布鲁斯半岛1783年的环宽年表，我们还有一个尚未公布的跨越近3000年的年表。丰富的亚化石物质的发现清楚地证明了进一步扩展的潜力。支持者已获准使用圭尔夫大学加拿大研究团队在过去十年中收集的2500多个活的和死的树木核心和部分样本，并允许他们使用这些样本。他们建议对这些样本进行编目和分析，开发出最强的样本子集，用于树种气候分析。他们还建议制定两个新的年表，分别来自Escarpment的最西端和最北端，并在东部极端的布鲁斯半岛进一步取样，以便更完整地模拟西方热带气旋/IS的跨空间和跨时间的气候信号。该项目的第二年将致力于树状气候分析，以实现气候重建的目标。

This proposal seeks support for dendrochronological research on the long-lived conifer northern white cedar, found growing on the cliffs of the Niagara Escarpment in Canada. Previous research by Canadian scientists resulted in the development of a published 1,783 year ring-width chronology from the Bruce Peninsula in Ontario, and we have an unpublished extension of this chronology, which spans nearly 3,000 years. The potential for further extension has been clearly demonstrated through the discovery of abundant subfossil material. The proponents have been given access to, and permission to use, the entire collection of more than 2,500 living and dead tree core and section samples collected over the past decade by the Canadian research team at the University of Guelph. They propose to catalog and analyze these samples, developing the strongest subset of samples to use for dendroclimatic analysis. They also propose to develop two new chronologies, from the far western and northern extensions of the Escarpment, and to sample further on the Bruce Peninsula on the eastern extreme, in order to more completely model the climate signal of T. occidenta/is across space and time. The second year of this project will be dedicated to dendroclimatic analyses, toward the goal of climate reconstruction.
