With data and imagery captured via underwater cameras, we invite you to dive beneath Lake Ontario’s surface to learn about water quality monitoring and its recreation connection. This work contributes to ongoing efforts within the Lake Ontario National Marine Sanctuary with support from the National Marine Sanctuary Foundation’s Sanctuary Community Fund. Andrew Brainard, PhD, is the Executive Director of UFI, leading their monitoring, water quality assessment, and applied research programs. He also leads the UFI Scientific Diving program, logging numerous dives to deploy monitoring buoys in Lake Ontario.
