Reconstruction of climate and glacial history based on a comparison of varve and tree-ring records from Mirror Lake, Northwest Territories, Canada

This study compared the hydroclimatic signals recorded in annually laminated (varved) sediments and tree rings within a small study area in the Selwyn Mountains of the southwestern Northwest Territories/southeastern Yukon Territory border region of Canada. The records were located immediately adjacent to each other and within 6 km of instrumental meteorological and hydrometric records, which permitted a detailed analysis of climate in the area from AD 1704 to 1996. This study explored the challenges of annually- resolved multi-proxy hydroclimate analyses and examined how best to interpret the climate record given the differences in proxy formation and the respective signals. The high-frequency (annual) variability from both proxies [...]
