Harmful Algal Blooms (HABs)
Harmful algal blooms (HABs) are scientifically complex, economically damaging, and a threat to ecosystem and human health.
Harmful algal blooms (HABs) are formed by dense populations of cyanobacteria (sometimes called blue green algae) that can produce toxins, threaten public health, and contribute to economic losses that exceed $2 billion annually. The Toledo water crisis in summer 2014 illustrated this threat, when a “do not drink” advisory was issued for unsafe levels of the harmful algal toxin microcystin in treated drinking water drawn from Lake Erie. With more than 400,000 people lacking drinking water for 2 days, the incident was reported worldwide and placed a spotlight on Lake Erie algal blooms as a threat to drinking water quality.
With our partners at NOAA GLERL, CIGLR is at the forefront of monitoring and forecasting HABs in Lake Erie, for the protection of human and ecosystem health. Our HAB research activities include:
1. Monitoring Harmful Algal Blooms
Water quality observations are essential for documenting the growth and spread of HABs. CIGLR and NOAA GLERL conduct regular field sampling in western Lake Erie and Saginaw Bay of Lake Huron during the July-October bloom season (field season is May-October). We sample and analyze temperature, Secchi disk transparency, algal parameters (chlorophyll, phycocyanin, phytoplankton abundance, algal toxins (microcystins and saxitoxins), and nutrients (phosphorus, nitrogen, carbon). We perform laboratory genetic tests to detect toxic populations of cyanobactera and determine how HABs are responding to water temperature and nutrients. Buoys and sensors deployed in western Lake Erie provide continuous water quality data during the bloom season. Data are available to the public for years 2009 to present (weekly monitoring) and 2014 to present (continuous systems).
In 2017, NOAA GLERL and CIGLR began field deployments of the first 2nd Generation Environmental Sample Processor (2G ESP) to be used in fresh water. The ESPniagara is an underwater robotic laboratory, or “lab in a can”, that collects and analyzes water for microcystin and communicates the results to data servers at GLERL in near-real time. Traditional lab techniques to determine algal toxin levels take days to complete. The ESPniagara provides drinking water managers with an earlier warning of algal blooms and their toxicity, enabling them to take action to protect public health sooner. The ESPniagara is deployed 5 miles west of the Toledo drinking water intake structure to get an early warning of elevated toxicity levels encroaching from Maumee Bay. Despite these advances, 2G ESPniagara‘s fixed mooring fails to fully support the information needed to predict HAB toxicity and fulfill the needs of drinking water intake managers. To fill this gap, a project team consisting of CIGLR, NOAA GLERL, NOAA National Centers for Ocean Coastal Science (NCCOS), and Monterey Bay Aquarium Research Institute (MBARI) is testing a new mobile HAB detection technology that will facilitate toxin forecasting and genomic observations at much greater frequency and in more areas of the lake. A new mobile 3G ESP will allow for weeks of flexible and targeted sampling, providing near real-time toxin and genomics measurements for integration into Lake Erie HAB toxicity forecasting products.
2. Predicting Future HABs
CIGLR and NOAA scientists use water quality data along with satellite data, weather forecasts, and water movement forecasts to predict future HABs in western Lake Erie. They have developed a specialized tool called the Lake Erie HAB Forecast (formerly the Experimental Lake Erie HAB Tracker) that gives current bloom conditions and a 5-day forecast of algal bloom movement and size through 3D simulations and graphics. These predictions can provide stakeholders, such as drinking water intake managers, commercial fishing operators, and beach goers, with timely information for public health decision making. Our team is currently using observed data to improve 3D prediction capabilities and developing methods to incorporate toxin concentrations into the model.
We are developing a new model for Lake Erie to examine relationships between HABs and key environmental factors like water temperature, river flows, nutrient loads, water column mixing, and sediment resuspension. Outcomes from the various loading-response scenarios will be used to develop relationships between nutrient loads and HABs in western Lake Erie.
3. Great Lakes 'Omics
Improvement of cyanobacterial Harmful Algal Blooms (cHABs) products is vital for protecting human health and is key for furthering our understanding of the possible connection between toxin potential, bloom toxicity, and environmental conditions. However, through ‘omics techniques we may be able to connect the presence of the microcystin gene with microcystin concentration and environmental conditions.
Scientists from CIGLR and NOAA GLERL are working together to provide further targeted investigations on the effects of environmental conditions on microcystin production in the lake. This project will provide critical information on HAB diversity, biology, and toxicity and will advance our knowledge of bloom ecology. It will improve our understanding of key traits associated with Microcystis’ life history strategies and impacts on the food web and society.
4. Incorporating Human Dimensions
To meet the needs of coastal communities, public health officials, and local water quality managers and decision-makers, the research team includes social scientists that are addressing the human dimensions of HABs in the Great Lakes. With the development and dissemination of our research products, we serve a wide range of users both public and private who shape the health and quality of the Great Lakes. The overall goals of this work are to: 1) identify and assess user needs related to water quality and human-health forecasting; 2) disseminate NOAA/CIGLR research, tools, and technology to end users to educate and build a network that will utilize NOAA products and information for decision making; and 3) guide the development and refinement of research project products.
The human dimensions team is conducting primary research that expands models of HABs and their impacts on water quality, with social dimensions that predict human behavioral responses to HABs or their impact on coastal communities. In addition to primary research, the team is leading outreach and stakeholder engagement efforts that facilitate the co‐design of research between scientists and stakeholder groups. They work with key user groups (e.g. drinking water managers, local officials, beach managers) and the general public to develop research into data products, like HAB forecasts and monitoring updates, that are easy to use and incorporate into user decision-making. They are also forging partnerships and networks with new stakeholder groups, including the recreational and charter fishing communities in the Great Lakes, through the use of human dimensions frameworks.

A new tool to safeguard drinking water is now keeping a watchful eye on Lake Erie. A robotic lake-bottom laboratory tracks levels of dangerous toxins produced by algae that bloom each summer in the lake’s western basin. The goal is to provide advance warning to municipal water managers and thereby prevent a recurrence of the water crisis that left more than 400,000 Toledo-area residents without safe drinking water for about two days in early August 2014 due to high levels of microcystin toxins.
