报告题目：Climatic value of Thule architectural wood remains from northwestern Alaska (AD 850-1650): a dendroarchaeological approach

摘要：
Northwestern Alaska is a key region for understanding settlement dynamics of the beginning of the second millennium AD in the American Arctic. During the transition from the Medieval Climate Anomaly (MCA) to the Little Ice Age (LIA) (AD 1100-1400), the Thule culture, considered the direct ancestor of today’s Inuit, appears along the coasts of northwestern Alaska (Mason et Gerlach 1995; Mason 2017). During the 13th century, Thule groups start settling along rivers in interior Northwest Alaska and colonizing the eastern Arctic to Greenland. The poor resolution of regional environmental proxies used to characterize the MCA-LIA transition is a limit to detailed temporal and spatial analyses of the complex interactions between climate, resources and people (Mason et Gerlach 1995; Nicolle et al. 2018). 
Archaeological wood remains are well-preserved in Thule coastal sites of Northwestern Alaska. As early as the 1940’s, archaeologist James Louis Giddings understood the potential of architectural wood remains for tree-ring research in Alaska. He built the first millenary chronology (978-1948 AD) in Alaska based on trees and archaeological samples from the Kobuk River Valley (Giddings 1941; 1952). This sequence allowed him to absolute date archaeological sites for the first-time. Along the treeless coast of northwestern Alaska, the main wood resource is driftwood originating from the boreal forests of Interior Alaska. The difficulty of dating driftwood due to its multiple origin and the development in the 1950’s of radiocarbon dating led to the near-abandonment of dendroarchaeological research in Alaska.
Since the 1990’s, researchers have collected architectural wood from coastal Thule sites covering the last 1000 years. These dendroarchae.
