A Photosynthetically Active Radiation (PAR) sensor is used to measure the spectral range of light that is available in the water column for use by primary producers for photosynthesis (400-700 nanometers), and how that varies over time and depth in the water column. Chlorophyll, the most abundant plant pigment in land plants and in ocean phytoplankton, is most efficient at capturing red and blue light.
