This time series of Harmonized Landsat and Sentinel-2 (HLS) imagery from August 28 to November 6, 2024 shows the explosive growth and decline of these blooms, which form when a flood of nutrients meets warm water and abundant sunlight. Under these conditions, toxic cyanobacteria can multiply rapidly, releasing liver-damaging toxins that threaten public health.",
