Stone Lab Buoy Tracks Algae
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 Technology to devise a monitoring solution that would fit their needs. In addition, the platform would need to be versatile enough to meet the lab’s mission of education, research and outreach. Finding the right fit Stone Lab researchers eventually selected a NexSens CB-800 (now the CB-650) data buoy with an integrated cellular data logger, solar panels and rechargeable batteries. The platform was donated by Fondriest Environmental, NexSens’ exclusive distributor, and met their requirements for such a monitoring asset that would provide students and researchers with important algae data while also being highly visible to those boating by or visiting the lab.
Expanding Algal Bloom Monitoring Network
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 different universities, cities and government agencies have launched more than a dozen data buoys, all armed with algae sensors, to do the job. One of the prominent agencies involved in the work is the National Oceanic and Atmospheric Administration. In the summer of 2015, scientists at the agency added four new platforms to the algal bloom monitoring network that has taken shape since the Toledo crisis. Three of these buoys were launched in the summer of 2015 near Maumee Bay and at other points off the shore of Michigan.
Great Lakes Buoy Networks
The Great Lakes region is a dynamic ecosystem that supports millions of people, plants and animals. 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 agencies and universities. Maintaining these networks, including servicing old buoys or launching new ones, is a big and important job. In one example of the ongoing work to support buoy networks, researchers with the University of Wisconsin launched two new monitoring buoys to track a variety of water quality parameters. The new platforms contribute data to the National Data Buoy Center, Great Lakes Observing System (GLOS) and the University of Michigan’s Ocean Engineering Lab.
