Researchers in Alberta are closely monitoring blue-green algae, and the public can now track this phenomenon through a newly launched website. The Algal Bloom Tracker allows users to monitor toxic algal blooms in six lakes using satellite imagery and lake sampling, providing real-time updates on a user-friendly map.
Rolf Vinebrooke, an aquatic ecology professor at the University of Alberta and part of the research team, explained that the map gets updated with satellite images capturing the lakes, offering a comprehensive view of the blooms and identifying areas to avoid.
Blue-green algae, scientifically known as cyanobacteria, can proliferate in Alberta lakes during the summer, posing health risks due to toxin production. Vinebrooke highlighted the dynamic nature of these blooms, emphasizing the importance of satellite tracking for timely monitoring.
The Algal Bloom Tracker is currently operational for six lakes and aims to expand to approximately 50 lakes in Alberta within the next three years. The lakes selected for monitoring represent a range of bloom frequencies, from rare occurrences at Sylvan Lake to frequent blooms at Lac La Biche.
When blue-green algae levels exceed safety thresholds, Alberta Health Services issues health advisories, with more than 25 currently in effect across the province. People are advised to avoid contact with affected water bodies to prevent health complications.
The Algal Bloom Tracker complements official advisories by providing additional information for public awareness. Vinebrooke stressed the importance of using common sense and following health advisories when choosing recreational water bodies to ensure safety.
Moreover, the project aims to enhance understanding of algal blooms and their impacts on various aspects of Alberta’s environment and communities. The website associated with the project underscores the significance of monitoring harmful algal blooms for stakeholders and the general public.
