Establishing the Chronologic and Climatic Correlates of LateHolocene Cultural Development in Northwest and Northern Alaska

本提案的目的是建立一个框架，以模拟阿拉斯加北极全新世考古遗址与全球和区域气候模式的关系。将利用考古遗址的亚化石木材、在西北部的Kobuk河地区收集的活树和浮木，将树木年轮数据扩展到1000-2000 BP。这些树木年代学数据可以用来重建过去的气候模式和确定考古遗址的年代。该项目的研究结果将大大扩展对北极西部文化发展和人类适应的年代学的理解，并有助于对全球气候变化的理解。

The purpose of this proposal is to establish a framework needed to model Holocene archaeological sites in Arctic Alaska in relation to global and regional climate patterns. Subfossil wood from archaeological sites, living trees and driftwood collected in the Kobuk River area in northwestern will be used to extend tree-ring data back to 1000-2000 BP. This dendrochronological data can be used to reconstruct past climate patterns and date archaeological sites. The results of this project will significantly expand the understanding of the chronology of cultural development and human adaptation in the western Arctic, and contribute to an understanding of global climate change.
