The NOAA Great Lakes Harmful Algal Blooms (HABs) and Hypoxia program is a collaborative effort between scientists at GLERL and the Cooperative Institute for Great Lakes Research (CIGLR). Our team is focused on understanding ecosystem health effects in the Great Lakes related to human-influenced water quality degradation. We use an integrated approach to understand the environmental drivers of and predict HABs and hypoxia. This approach consists of using satellite images, remote sensing, buoys, a comprehensive monitoring program in Lake Erie, Saginaw Bay, and Lake Huron, and advanced genetic techniques to understand the long and short-term seasonal dynamics of HAB and hypoxic events. The data we collect is used to inform predictive models used by key Great Lakes stakeholder groups, such as drinking water managers. Effective management of coastal ecosystems requires timely and continuing predictions of ecosystem change. Our research will improve forecasts of water quality to reduce risks to ecosystem health associated with recreational exposure, consumption, and treatment of Great Lakes water.
