USGS dive team members Marc Blouin and Glen Black carrying an ADCP (Acoustic Doppler Current Profiler) into Lake Michigan to measure currents throughout the summer season in order to improve predictive modeling at recreational beaches and better predict E. coli concentrations in the water, therefore improve safety of swimmers.
