Using Paleolimnology to Evaluate Human Impacts on Lakes
I have a long-standing interest in human interactions with the environment and have studied prehistoric human impact on lakes, as well as modern pollution history (acid rain, eutrophication).
Various studies by my lab group have used the stratigraphic record of the last few hundred years to assess the temporal stability of lakes and the magnitude of the human impact from agriculture, urbanization, and atmospheric deposition.
