Expanding Algal Bloom Monitoring Network

Expanding Algal Bloom Monitoring Network

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.

Lake Lacawac Profiling Platform

The Lacawac Sanctuary and Biological Field Station overseen by Miami University’s Center for Aquatic and Watershed Sciences is home to lots of exciting research projects. Its namesake, Lake Lacawac, is part of the Global Lakes Ecological Observatory Network, an expansive group of scientists worldwide who study how lakes respond to environmental change. Because of that status, it makes sense that data collected at the sanctuary are used in projects near and far.There are plenty of interesting water quality research projects going on there, relying on gear like secchi disks, handheld meters and plankton nets. But in addition to those, there is new and inventive research afoot at Lacawac Sanctuary.One of those involves a custom auto-profiling platform developed by scientists at Miami University with help from NexSens Technology. It supports topside sensors, as well as a profiler that uses a creative winch system to lower and raise water quality sensors through Lake Lacawac’s water column. Taking that approach, Lake Lacawac investigators are looking to make new finds relating to the interactions between Lacawac’s water and the atmosphere, as well as answer key questions on dissolved organic carbon levels.

Monitoring Platform Protects Native Culture

The Penobscot River is at the heart of Penobscot Indian culture. For hundreds of years, the tribe has looked on it as a source for food and medicine, as well as a means of transportation. But in recent years, algal blooms have gotten worse in the river, believed to be caused by phosphorus discharges from a paper processing plant.Not long after the plant was fined and ceased operations, the Penobscot Indian Nation secured funding to launch a water quality monitoring platform on the river. The platform serves as a guardian both to the Penobscot River and to the culture that still thrives around it today.The platform was deployed in Dolby Pond, one of the Penobscot River’s impoundments. It launched in 2007 after an especially bad algal bloom that was connected to the paper mill upstream. After a short boat ride out to it, the floating platform allows workers with the Penobscot Nation’s Water Resources Program to check on monitoring equipment at a comfortable standing position. It was built by the Nation as a hands-on project that helped connect tribe members to the effort by giving them a way to chip in.
