UW-Green Bay will fabricate and deploy three monitoring buoys along with “autonomous underwater vehicles” (AUVs) to continuously measure critical water quality parameters in the bay of Green Bay. This equipment will help researchers identify and map hazardous algal blooms and the dead zone in the bay in greater spatial detail. The AUVs will also enable the collection of unique winter data to better understand under-ice processes which represent a large gap in our current understanding of the Green Bay ecosystem and the Great Lakes as a whole because buoys are removed for the winter. The sensors attached to the buoys collect water quality data including water temperature, dissolved oxygen, chlorophyll-a, and phycocyanin concentration.
