Even before the Toledo Water Crisis, researchers at Stone Lab were concerned with the algae blooming in Lake Erie. With their location on the lake’s Gibraltar Island, it was easy for them to see the tides whipping up green stuff each day in the summer months. So long before the crisis, which took place in August 2014, scientists at the Ohio State University lab began working with engineers at NexSens […]

Just one year after the Toledo water crisis of August 2014, federal, state and local agencies have stepped up to make sure that cities around Lake Erie’s western basin continue to have access to safe drinking water. Much of assuring that requires around-the-clock monitoring of water quality conditions there. Since the western basin is so large, not just one monitoring platform will do. Accordingly, researchers and water quality managers from […]

Key to maintaining its vitality is making sure the waterways that sit at its base remain clean and healthy. To do that, scientists and water managers need steady, reliable data. They often get this information from buoy networks. There are many different Great Lakes buoy networks out there, which are largely supported by government […]
