Collection of water and phytoplankton for metals analysis in Lake Mendota, Wisconsin. M3 Research Lab researchers collect in two to five liter containers and then filter and size fractionate the samples at the lab process these samples back at the lab to determine the amount of mercury and metals entering the food web.

Water-quality sonde to be deployed from May through October in Grand Rapids, Michigan, to collect 15-minute measurements of dissolved oxygen, conductance, water temperature, turbidity, fluorescent dissolved organic matter (fDOM), and tryptophan-like fluorescence. This end-on view of the water-quality sonde shows each of the individual sensors.
