IDAHO STATE UNIVERSITY
A major goal of the Arctic System Science (ARCSS) Program is to understand the variability of the Arctic system and the feedbacks that lead to pronounced system changes, such as those that are currently taking place. Rapid changes in the Arctic climate system that occurred in the relatively recent past can be compared with the output of climate models to improve the understanding of the processess responsible for nonlinear system change. In particular, this study focuses on the transition between the Holocene thermal maximum (HTM) and the onset of Neoglaciation, and on the step-like changes that occurred subsequently during the late Holocene. The millennial-scale cooling trend that followed the HTM coincides with the decrease in Northern Hemisphere summer isolation driven by slow changes in Earth's orbit. Despite the nearly linear forcing, the transition from the HTM to the Little Ice Age (1500-1900 AD) was neither gradual nor uniform. To understand how feedbacks and perturbations result in rapid changes, a geographically distributed network of proxy climate records is proposed to study the spatial and temporal patterns of change, and to quantify the magnitude of change during these transitions.

| Quarterly Activities/Project Description |
During this period, graduate and undergraduate students and the PI worked on several components of this project: 1) Laboratory analyses on sediments, including a suite of core analyses focused on lake-level reconstructions. a) Continued analyses on cores from Little Harding, including stable isotopes, AMS radiocarbon chronology and correlation. b) Stable isotope analysis of cores from Harding Lake is complete, and a paper has been drafted interpreting the data. c) Continued to synthesize data from my previous studies in the area into this project, for a synthesis manuscript on interior Alaska Holocene paleoclimate, focused on lake-level change and paleohydrology. 2) Graduate student mentoring. The project included funding for graduate student Shannon Brady, who is completing the second year of her M.S. program. I mentored her during this period towards her research project associated with this grant. |
