• Electric blue plankton blooms off Ireland

    Date:16 October 2013 Tags:, , ,

    Resembling the brush strokes of French Impressionist Claude Monet, electric blue-coloured plankton blooms off Ireland, North Atlantic Ocean, in this Envisat image. Plankton, the most abundant type of life found in the ocean, are microscopic marine plants that drift on or near the surface of the sea.

    While individually microscopic, the chlorophyll they use for photosynthesis collectively tints the surrounding ocean waters, providing a means of detecting these tiny organisms from space with dedicated “ocean colour” sensors such as Envisat’s Medium Resolution Imaging Spectrometer (MERIS), which acquired this image at a resolution of 300 metres.
