For my internship, I studied the effect of plankton bloom density on concentrations of mercury in Carnegie Lake, Princeton. Working with a team of students lead by Dr. Eileen Zerba, I collected samples from the lake and brought them back to Professor Francois Morel’s lab in the Department of Geosciences for analysis. In addition to analyzing the levels of mercury and methylmercury in plankton, I also measured mercury in water, sediment, macroinvertebrates, and fish, to get a full profile of mercury cycling in the lake.
