Photosynthetically Active Radiation (PAR) measures irradiance or the amount of sunlight or ambient light that diffuses through water compared to surface light. PAR focuses on the dynamics of the photic zone, typically 1-5 meters below the surface, and leads to an understanding of photosynthesis, toxic algae blooms, and eutrophication (nutrient loading).
