Interpretation Of The High Resolution, Multivariate Mt. Logan (Yukon Territory) Ice Core - A Record Of North Pacific Climate And Atmospheric Chemistry, Paul Andrew Mayewski

University of Maine Office of Research Administration: Grant Reports

The recently developed Mt. Logan ice core glaciochemical dataset provides an unprecedented opportunity to understand Holocene climate change and the sources and fluxes of natural and anthropogenic chemicals in the North Pacific atmosphere. The 185 m-long ice core has been sampled at very high resolution using a refined and updated continuous ice core melter system, and analyzed for over 40 chemical species, including major ions, trace elements, rare earth elements, and stable isotopes. Subseasonal samples spanning the top ~500 years allow for annual layer counting, followed by ice flow modeling for the remainder of the timescale spanning the Holocene and …
