Summary: This animation visualizes the growth and decline of cyanobacteria abundance and harmful algal blooms (HABs) in the Great Lakes, particularly Lake Michigan and Lake Erie, during the summer of 2024.

This video provides a time-lapse visualization of cyanobacteria abundance, including harmful algal blooms (HABs), across the Great Lakes region from mid-July to early September 2024. The map uses a color scale from blue (low abundance) to red (high abundance) to show the concentration of cyanobacteria. Key observations include the persistent presence of an intense bloom in Lake Michigan and the significant development of a large, high-abundance bloom in the western basin of Lake Erie. The animation tracks the spatial and temporal changes of these blooms, demonstrating their progression and intensity over the summer months.
