Dr. Norton will explore the the chronology and formation of Maine’s lakes, the evolution of the soil chemistry and water chemistry during the last 16,000 years, a bit about the major responses of lake water chemistry to this evolution, the detailed history of anthropogenic air pollution as seen through the lens of sediment chemistry, and conclude with the life-after-death history of a Maine lake.
