Summary
Abstract: Antarctic ice provides an archive of Earths atmospheric composition over time. It therefore records evidence of human impact on the atmosphere. Lead is a toxic element, whose isotopic fingerprint can also be used as a tracer. This project will investigate a 400 year Pb pollution record in ice from Law Dome.
