Psychedelic Swirls Show Algae Bloom from Space

Psychedelic swirls decorate the Baltic Sea in a stunning new satellite image. The Operational Land Imager on the Landsat 8 satellite snapped the image on Aug. 11, according to NASA's Earth Observatory, when land-based observers reported massive blooms of cyanobacteria. The summer Baltic is prime cyanobacteria territory, according to NASA: Sunlight is abundant, and the waters are nutrient rich.
