An effective method for evaluating chlorophyll “a” is remote sensing in the optical range by satellite spectroradiometers. To study the concentration of chlorophyll “a” in the bio-productive regions of the ocean, we used data from the MODIS-Aqua scanner of the NASA GIOVANNI system, which provides access to satellite data archives at the same time as tools for their processing and analysis. The variability of the chlorophyll “a” concentration in surface waters may indicate the state of water productivity. The paper considers the temporal and spatial variability of chlorophyll “a” concentration and water surface temperature from satellite data and the influence of water surface temperature on this variability in the Gulf of Alaska and in the area of the Peruvian upwelling. As a result, a direct relationship between changes in the concentration of chlorophyll “a” and the water surface temperature was revealed. It is possible to assess the bio-productivity depending on the variability of the concentration of chlorophyll “a”.
