University of Maine Office of Research Administration: Grant Reports

This award supports a project to analyze samples from the Law Dome ice core for volcanic tephra. The Law Dome ice core is the best-dated ice core from East Antarctica and contains a detailed record of climate and atmospheric chemistry over at least the last 700 years. Several global volcanic eruptions appear to be recorded in the Law Dome core, including the well known Tambora 1815 and Unknown 1809 events, as well as the Huaynaputina 1600 and Ruiz 1595 events.
