Topic: Sub-annual perspectives in Western US Dendroclimatology
The discipline of dendrochronology (the study of tree-rings), has aided in archaeology, climatology, hydrology and more since the early 1900s. My research primarily focuses on examining past climates utilizing tree-rings. The strength of using tree-rings to date structures or reconstruct climate lies in its finely resolved temporal resolution. Tree-rings are one of only a few proxy records with annual resolution. Recent work has been able to improve the resolution to a sub-annual scale, consisting of a warm (May through September) and a cool (October through April) season. In this talk, I will elaborate on the methodology used to examine sub-annual rings including new novel methods I’ve developed. I will also present my research on utilizing these methods to examine droughts, snowpack, and other regional paleoclimate phenomena.
