A team of researchers in Alberta is closely monitoring blue-green algae, and the public now has access to a new website for tracking these algae blooms. The Algal Bloom Tracker provides real-time updates on toxic algal blooms at six lakes using satellite imagery and lake sampling, all conveniently displayed on an interactive map.
According to Rolf Vinebrooke, a professor of aquatic ecology at the University of Alberta and one of the project researchers, the map is regularly updated with satellite images of Alberta lakes. This method offers a comprehensive view of the entire lake, aiding in identifying the nature of the blooms and areas to avoid.
Blue-green algae, scientifically known as cyanobacteria, can rapidly multiply in nutrient-rich Alberta lakes during the summer, posing health hazards due to toxin production. Vinebrooke emphasizes the dynamic nature of these blooms, emphasizing the importance of satellite monitoring for timely tracking.
The Algal Bloom Tracker currently covers six lakes, including Ethel Lake, Lac La Biche, Nakamun Lake, Pigeon Lake, Sylvan Lake, and Wabamun Lake, selected to represent varying bloom frequencies. Plans are underway to expand the tracker to approximately 50 lakes across Alberta within the next three years.
When blue-green algae levels exceed safety thresholds, Alberta Health Services issues health advisories for affected lakes. Presently, over 25 advisories are active across the province, warning against contact with algae blooms to prevent health risks. The Algal Bloom Tracker, although separate from official advisories, serves as a valuable resource for public awareness and informed decision-making.
The project’s website not only aids in monitoring algae blooms but also aims to enhance understanding of these occurrences and their impacts on recreation, tourism, real estate, and Indigenous communities in Alberta.
