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in the development of a published 1,783 year ring-width chronology from the Bruce Peninsula in Ontario, and we have an unpublished extension of this chronology, which spans nearly 3,000 years.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.

该提案寻求支持对长寿的针叶树北部白雪松的DendroConological研究，发现在加拿大的尼亚加拉悬崖上生长。 加拿大科学家的先前研究导致了从安大略省布鲁斯半岛发表的1,783年的环形宽度年表的开发，我们对这一年表的未发表延伸持续了近3，000年。通过发现丰富的亚物质材料，已经清楚地证明了进一步扩展的潜力。支持者可以访问和使用允许使用的全部收藏，这些收藏是圭尔夫大学加拿大研究小组在过去十年中收集的2500多个生物和枯树核心以及部分样本。他们建议对这些样品进行分类和分析，从而开发出用于树枝状气候分析的样品的最强子集。他们还建议从悬崖的远西方和北部扩展中开发两个新的年代，并在东部极端的布鲁斯半岛上进一步采样，以便更彻底地模拟T. Occidenta的气候信号。该项目的第二年将致力于树突气候的分析，以实现气候重建的目标。
