Adaptive Sampling RAS Tracks Plume Events

Scientists from the University of Wisconsin deployed a McLane RAS-500 with adaptive sampling to study bacterial loading in the Great Lakes area. The buoy based system collected samples using activity triggered, time-series sampling. Significant patterns of contamination events were linked to heavy rainfall. The UW team wrote an application program interface (API) triggering the automatic start of
