MERIS satellite image shows blue-green algae blooms

Envisat Medium Resolution Imaging Spectrometer (MERIS) satellite image acquired July 11, 2010 shows blue-green algae blooms in the Baltic Sea. The term "Algae bloom" is used to describe the multiplying of phytoplankton, microscopic marine plants that drift on or near the surface of the sea. While individually microscopic, the chlorophyll that phytoplankton use for photosynthesis collectively tints the surrounding ocean waters, providing a means of detecting these tiny organisms from space with dedicated 'ocean colour' sensors. Germany, Sweden, Estonia, Latvia, Lithuania, Russia and Poland are pictured bordering the sea.
